Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a holding device for a Spulgut suction gun. Furthermore, the invention relates to a holding device with such a holding device and a winding machine with a holding device for a Spulgut suction gun. The invention also relates to a method for transferring a Spulguts at the end of a winding process of a first coil on a winding station of a winder to a second spool, which is co-wound on the same winding station of the winder, wherein a Spulgut suction gun and a holding device for this are used.

STATE OF THE ART

Spool material suction guns are known, which are used for handling a Spulguts in the production of the Spulguts and the winding of the Spulguts by a winder insert. By means of the Spulgut suction gun, a sucking air flow is brought about by which forces can be exerted on the Spulgut, the Spulgut can be caught in the region of a suction opening of the Spulgut-suction gun and / or the Spulgut with the air flow in an opening, a channel or a Receptacle of Spulgut suction gun "sucked" can be. In the following, these functions fulfilling suction devices are referred to as "Spulgut suction gun" regardless of whether they are designed as a kind of "gun" or in other structural design. Spool material suction guns can be used, for example, if a disturbance results in a winding machine, so that a continuous material produced in a continuous production process can not be removed continuously by the winding machine. In this case, the Spulgut can be sucked off continuously via the Spulgut suction gun. If a material to be spooled is located in the intake area of a spool material suction gun, the product to be spooled can also be supplied to a desired location via the spool material suction gun. In particular, the Spulgut the spooling machine can be supplied via the Spulgut-suction gun and, for example, a suitable catching a rotating spindle of the winder or a catcher of a driven by a spindle sleeve are supplied. Such Spulgut suction gun is for example off DE-OS 19 36 916 known, wherein the present invention can be used in connection with any type of Spulgut suction guns use.

WO 2005/019081 A1 describes a winding machine, in which successively wound at a winding station coils. The winding material wound here is threads or tapes, for example a stretched single-layer or multi-layer plastic tape. On the output side of the production process for the winding material, the material to be spooled passes over a deflecting roller rotating about a stationary axis, a spring-supported dancer roller and a further deflection roller with fixed rotational axis to form a Spulgutleitwerk. In the Spulgutleitwerk the Spulgut over a supported on the Spulgutleitwerk deflection, here a straight or curved trained overflow bar, to a traversing, which can be moved depending on the desired laying pattern for the Spulgut on the coil to be created any parallel to a rotation axis of the coil. From the traversing spool guide, the material to be wiped passes to a pressure roller, by means of which the wadding is applied with a contact pressure to a spindle or a sleeve carried by the spindle or already created windings. In order to allow an adjustment of the rotational axis of the pressure roller and a pressing with increasing diameter of the winding, the Spulgutleitwerk with pressure roller, Changierspulgutführer and deflection is pivotable about an axis which is oriented parallel to the axis of rotation of the coil.

While the actual winding process can be easily controlled in full automation, problems arise in the manually induced change at the end of the winding process of a first bobbin to a subsequent winding process for a second bobbin. For this purpose, it is necessary to manually cut at the end of the winding process, the continuously tapered winding material, which usually takes place between the traversing yarn guide and this upstream yarn guide, in particular a deflection bar or a guide roller. After severing the Spulguts the running on the bobbin end of the Spulguts is wound on this, while sucked by a Spulgut-suction gun, the further tapered Spulgut and is absorbed. Following this, the Spulgutleitwerk is moved away with the pressure roller of the full first coil. The spool is decelerated and any locking of the spool on the spindle is eliminated, thereby allowing the spool to be removed from the spindle. It can then be applied to the spindle a new empty sleeve, which is then optionally locked with the spindle and is rotated by them. By means of the Spulgut suction gun can then be done such a handling of the Spulguts the Spulgut the empty shell or a suitable catching device of the sleeve or the spindle is supplied. Then the Spulgut between spindle or sleeve or second coil and Spulgut suction gun is severed, so that the winding process for the second coil can begin. The problem here is that during the previously described change process, the operator of the winding machine must hold the suction in his hand, which this only one hand is available to remove the first coil of the spindle and apply the empty sleeve on the spindle and to operate the winder. Under certain circumstances, this requires the implementation of the bobbin change with two people. It is also possible that the operator deposits the Spulgut-suction and resumed later, which is cumbersome. In any case, the position of the Spulgut-suction gun, and thus a reference point of the continuous Spulguts, placed in the discretion of the user. The spatial movement of the Spulgut suction gun, which must first catch the Spulgut between traversing and Changierspulgutführer, then holds the Spulgut during the first cutting, then at a remote location the Spulgut a catching device of the spindle or sleeve of the second coil supplies and then the second cutting is also made at the discretion of the user. This has the result in practice again and again that during the changing process, the Spulgut undesirably leaves a deflection, a pulley or a dancer roll. In the best case, the operator must lead in such a case by means of Spulgut suction gun the Spulgut about diverting pulley, dancer roll and / or deflection, which requires his full attention and requires additional time, in which continuous material is produced, which is not one Coil can be wound. In the worst case, it comes in the face of improperly managed Spulguts to a machine failure.

Another solution of the invention underlying object is given by A further embodiment of such a method results in accordance with the dependent claims 17 and 18.

DESCRIPTION OF THE INVENTION

According to the invention it is proposed for the first time that a holding device for a winding material suction gun is used. This fixture specifies a defined location at which the operator can arrange the Spulgut-suction gun, can remove the hands of the Spulgut-suction gun and, for example, after a few steps, then again record the Spulgut-suction.

In the holding device according to the invention, the Spulgut suction gun can be kept in an absorbent state, in which this so receives continuously supplied Spulgut.

The holding device according to the invention has an arbitrarily shaped receptacle for the Spulgut suction gun. The recording here is an introduction for the Spulgut suction gun.

Furthermore, the holding device according to the invention has a fastening element by means of which the holding device can be fastened to a winding machine at a defined position and in a predetermined orientation. In this case, the holding device can be attached via the fastening element, for example, to a Spulgutleitwerk or to a housing of the winder. To name just a few examples here, the attachment element of the holding device may be a mounting flange, a mounting carrier, bores, elongated holes, threads or the like.

In addition, the holding device has a guide member. This guide member defines an entrance area of the Spulguts in the holding device. The guide member thus holds the Spulgut in the desired entry area of the holding device when the Spulgut suction gun is removed from the holding device and is moved freely outside the same, for example in the direction of the spindle to perform the change. Here, the position of the entry region is selected in the holding device such that it is ensured that upstream of the entry region, the Spulgut not any deflection means, pulleys u. Ä. Leave, whereby the problems explained above are eliminated.

Finally, the holding device according to the invention has a Spulgut output slot. This is formed open against the insertion of the Spulgut suction gun into the receptacle of the holding device. Preferably, the Spulgut output slot opens into the opening of the holding device, through which the Spulgut-suction gun is inserted into the receptacle. If the Spulgut-suction gun is introduced into the receptacle of the holding device and then sucked the Spulgut in the Spulgut suction gun, the Spulgut suction gun could not be removed from the holding device without the Spulgut exit slot according to the invention and moved in the direction of the spindle of the winder, without that the material to be spooled would be deflected several times in the holding device, which could lead to impairments of the Spulguts up to a rupture of the Spulguts. By contrast, the Spulgut output slot allows the Spulgut suction gun is taken with this sucked Spulgut from the fixture and with the movement of the Spulgut suction gun in the direction of the spindle Spulgut at least without contact of the Spulguts with the holding device on the spindle side facing the holding device can pass. In other words, the Spulgut output slot allows the Spulgut suction gun can be removed with this incoming Spulgut from the holding device and can be moved outside the same without an excessive number of contact points with the holding device or deflection exists.

For a first embodiment of the invention, the Spulgut output slot is formed continuously and open on both sides. It is also possible that the holding device is open on both sides, so that the Spulgut suction gun can be inserted through an opening in the holding device and can protrude in extreme cases on the opposite side of the holding device. The Spulgut exit slot can then connect the two openings mentioned together. With removal of the Spulgut suction gun, the suction opening with her incoming Spulgut withdrawn through the recording, in which case for the free movement of the Spulgut suction gun outside of the holding device, the Spulgut depending on the position of the Spulgut suction gun along the Spulgut exit slot "wander" can.

For a second embodiment of the invention, the receptacle and the extent of the holding device are dimensioned such that in the receptacle inserted state of the Spulgut suction gun, the suction opening of the Spulgut suction gun is arranged in a Spulgutdurchtrittsraum the holding device. The Spulgut-passage space has transverse to the direction of insertion of the Spulgut suction gun openings. During normal operation of the winder, ideally, the wad may pass through the apertures and the wadding passage space without any contact with the retainer. For this embodiment, the holding device may be formed closed in the insertion behind the Spulgut. Preferably, said openings are formed with the Spulgut output slot and the guide member or these open into one another.

In a further embodiment of this embodiment of the invention, the fastening element and the receptacle are dimensioned and oriented such that the insertion direction of the receptacle for the Spulgut suction gun corresponds to the traversing direction of a traversing Spulgutführers. This embodiment is based on the knowledge that it may be uncertain where the traversing spool guide is located at the end of the winding process for the first spool. If the insertion direction of the holding device for the winding material suction gun is oriented parallel to the traversing direction, a different position of the traversing yarn guide towards the end of the winding process merely causes an interaction between the winding material suction gun and the winding material to be produced for different insertion depths of the winding suction gun into the receptacle is, but in any case, the suction opening of the Spulgut suction gun the Spulgut "hits". As a result, the process reliability can be increased.

Preferably, the openings of the Spulgut-guide space in a traverse plane extensions which are greater than the maximum movement of the Spulguts in the region of the holding device due to the movement of the traversing Spulgutführers. This configuration has the consequence that unwanted contacts between Spulgut and holding device are excluded during the winding process and the traversing movement of the traversing Spulgutführers that can lead to an increase in friction, a change in the thread tension and deterioration of Spulguts.

In a further embodiment of the invention, the holding device has an insertion region for the receptacle, for example with an insertion element, an insertion bevel or an insertion funnel. The insertion area can simplify the insertion of the winding material suction gun for the operator and make it more reliable.

While it is quite possible that a cutting of the Spulguts outside of the holding device is carried out by measures known per se, the holding device is equipped with a cutting device for cutting the Spulguts according to a further proposal of the invention. This may be any desired cutting device, for example a knife, a heated separating element, a laser or the like. Thus, according to the invention, the holding device can be designed to be multifunctional, in that it is responsible for the severing of the product to be spooled in addition to the previously described holding and changing function as well as the guiding function for the product to be spooled. In a particularly advantageous embodiment, the cutting device comes movement controlled by the movement of the Spulgut suction gun in the recording to effect. To name just a few examples, a cutting blade can be actuated by means of the winding material suction gun, which is moved transversely to the winding material and cuts it. It is also possible that the Spulgut-suction gun "takes" the Spulgut and this presses against the cutting device with thereby brought about cutting the Spulguts.

While basically any open, skeletal, carrier-like, partially closed or closed configurations of the holding device are possible, the invention proposes in a further embodiment, that the holding device is formed with a hollow housing open on one side. An interior of the hollow housing in this case forms the receptacle, in which case the Spulgut suction gun can be introduced through the open side of the housing in the recording.

In principle, any holding device can be used within the scope of the invention, which makes it possible to insert the product for the first time, allows the product to be taken through, predetermines the entry region of the product by means of the guide element and avoids unnecessary deflections of the product to be taken during the change with the product exit slit. For a particular proposal of the invention, a housing of the holding device in the region of its lateral surface is equipped with an opening into the receptacle H-shaped opening. Here are the two vertical leg and the horizontal leg of the H respectively Slits formed. The slot which forms the horizontal leg is oriented in the circumferential direction of the receptacle. Extending this slot approximately in the direction of Spulguts in the region of the holding device, the Spulgut can be introduced from above into the holding device via this slot. On the other hand, the slots forming the vertical limbs of the H are parallel to the insertion direction, that is to say preferably oriented in the traversing direction. The slot forming the horizontal limb of the H ends ends in the slots forming the vertical limbs of the H, so that after the introduction of the product to be winder through the first-mentioned slot, the wadding can enter the two slots forming the vertical limbs of the H. If the material to be winder passes through these two slots in the holding device, the slots allow the product to be moved during the traversing process without contact of the product with the boundaries of the slots. Here, one of the slots which form the vertical leg of the H, namely the slot which faces the spindle, the Spulgut exit slot, while the other one vertical leg of the H forming slot, namely the side facing away from the spindle slot, the guide member forms. By means of the H-shaped opening measures according to the invention can be realized in a particularly simple manner, wherein by designing the H-shaped aperture and the Querabmessungsverläufe the slots and the orientation and curvature of the longitudinal axes of the slots on the leadership behavior for the Spulgut in the holding device constructive can be acted upon.

While the holding device (and the receptacle) can basically have any desired cross-section, in a further embodiment the holding device has an annular cross-section, which is preferably advantageous if at least part of the winding material suction gun extending into the receptacle has a tubular cross-section has. In this case, the holding device may also be equipped with an insertion, which may then be funnel-shaped.

In principle, the cutting device for severing the Spulguts can be arranged in the change at any point inside and outside of the holding device. For a particular proposal of the invention, the cutting device is arranged in an end region of the Spulgut output slot. If, for example, with the Spulgut suction gun, the Spulgut brought into the end of the Spulgut output slots, this comes movement controlled to the plant to the cutter with the severing of the Spulguts. Since the Spulgut exit slot arranged on the spindle side facing the holding device is, the spindle facing the end of the Spulguts can be wound without further interaction with the holding device on the spool, while the "upstream" end of the Spulguts can be caught and sucked in the holding device by the Spulgut suction gun. While catching the Spulguts a Spulgutlänge between cutting device and entry of the Spulguts in the holding device form a suitable attack surface for the sucking air flow of the Spulgut suction gun.

In a further embodiment of the invention, the holding device may have a sensor. The sensor can detect a position, a movement, a pressing force and / or a presence of a winding material suction gun in the recording. It is possible here that the sensor is designed as a digital switch or forms a continuous signal. The sensor signal of this sensor can then be supplied to a controller for controlling further operations of the winder. To mention just a few examples here, triggered by the sensor, the operation of a cutting device, influencing the Zuführverhaltens for the Spulgut output side of the manufacturing process, influencing the drive of traversing device, the Spulgutleitwerks, the contact pressure of the pressure roller and / or the drive a Spindle or a pressure roller to drive the coil done. In particular, with sufficient insertion of the Spulgut-suction gun into the recording, with which the automated severing of Spulguts is triggered automatically the change of the coil can be initiated by directly or delayed deceleration of the spindle or spool takes place and, for example, time-delayed or falls below a predetermined speed of the coil unlocking between coil and spindle. If the bobbin comes to a standstill, the operator can remove the first bobbin from the spindle without additional measures and attach a new sleeve to the spindle. If the sensor then detects that the operator is removing the package suction gun from the receptacle, the control unit can automatically perform the locking of the sleeve and spindle and set the spindle in rotation in such a way that catching of the package can take place. Automated can then also be recognized that the Spulgut is created and captured: the force with which the Spulgut is sucked from the Spulgut-suction gun is smaller than the force generated in the Spulgut when the Spulgut is caught and wound , A suitable detection device for the tension of the Spulguts, in particular a detection device for a deflection of a spring-mounted dancer or a force sensor on a roller, thus can automatically detect the catch and the beginning of the winding process from an increase in the tension of the Spulguts, with which the winder in can change the usual control process for the winding of the coil, u. U. also with the onset of traversing movement. The user can then bring the Spulgut suction gun back into the receptacle and store there until the next change is pending. The aforementioned automation is merely an example of control and automation measures that can be brought about on the basis of a sensor signal.

While it is quite conceivable that the holding device is designed for itself and is arranged on a Spulgutleitwerk or another component of the winding machine at a suitable point downstream of a deflection or a guide roller, the holding device may also be part of a holding device, which also forms or carries the deflection , This simplifies assembly, since the unit provided with the holding device with integrated roller already predetermines the correct alignment of holding device, guide member and roller.

Another solution to the problem underlying the invention is given by a winder, which has at least one winding station on which successive coils are wound with a Spulgut, so not the Spulgut is mutually wound on different spindles at different winding stations, as in particular for winding machines with several, arranged on a revolver winding stations is the case. The winding machine according to the invention has a traversing belt guide and a deflection, which is arranged upstream of the traversing yarn guide, that is "upstream" of this is arranged. A holding device of the type described above for a Spulgut suction gun is disposed between the traversing yarn guide and the deflection means, in particular a deflection roller. The Spulgut is passed (during the winding process) by the holding device. Here, the Spulgut output slot of the holding device is arranged on the side facing the Changierspulgutführer, so that when removing the Spulgut suction gun and movement thereof in the direction of the spindle Spulgut a certain movement in the Spulgut exit slot can make without the Spulgut imperative The limits of the Spulgut-output slot comes to rest. By contrast, the guide member of the holding device is arranged on the side facing the deflection, so that this holds on the right side of the holding device the Spulgut in an entry region, that ensures that the Spulgut the deflection independent of any movement of the Spulgut suction gun not leaves.

Another object of the invention is based on a method with which a transfer of a product takes place at the end of a winding process of a first bobbin on a winding station of a winder to a second bobbin on the same winding station of the winder. For such a method u. U. initially at the end of the winding process of the first coil insertion of a Spulgut suction gun into a receptacle of a holding device for the Spulgut suction gun. However, it is also possible that in the holding device the Spulgut suction gun is already stored during the winding process. Before, with or after this insertion, the Spulgut suction gun is activated. There is the first cutting through the Spulguts, whereby one end is released to complete the winding process for the first coil. At the same time the tapered end is caught by the Spulgut-suction gun, which is activated / before, with or after the cutting of the Spulguts. Before, during or after the braking of the first coil and the removal of the first coil from the winding station then takes the removal of the Spulgut suction gun from the holding device. While then with the Spulgut suction gun outside of the holding device one end of the incoming Spulguts can be freely guided, the Spulgut is additionally guided by a guide member of the holding device. The guide is made such that the product to be spooled runs independently of the movement of the Spulguts with the Spulgut suction gun on the holding device upstream deflection, so this can not leave unintentionally. Subsequently, the application of the Spulguts done with the Spulgut suction gun for the beginning of the winding of the second coil, wherein the application can be made directly to the spindle, provided that it forms the spool without additional sleeve, or takes place on a sleeve. This is followed by a second severing of the Spulguts, which then takes place the winding process for the second coil. It is understood that the order of said method steps may also be different than previously described.

In a further embodiment of the method according to the invention for the first cutting of the Spulguts the Spulgut suction gun is moved in the receptacle and relative to a cutting device, so that the severing is motion-controlled by the Spulgut suction gun.

For a further proposal is detected in the inventive method via a sensor, whether the Spulgut suction gun is in the recording, the Spulgut suction gun is inserted into the receptacle or is a thread tension increases or decreases, the Spulgut-suction gun from the recording is moved and / or the first cutting of the Spulguts takes place. The sensor signal of the sensor then takes place via a suitable control device an automatic control or regulation. Here, a regulation of the feed rate of Spulguts done, a locking and / or unlocking the spindle with a sleeve or coil and / or a drive of the spindle done, as has been partially already explained above.

DESCRIPTION OF THE FIGURES

Fig. 1 shows a winder 1. The winder 1 is a Spulgut 2 fed. The Spulgut 2 is preferably prepared by a continuous production process and supplied continuously. The Spulgut 2 may be of any type, such as a thread or ribbon, twisted yarn, monofilament, a plastic tape u. in. In Fig. 1 not shown components of the winder 1 can be done a treatment of the Spulguts 2, for example, an influence on the cross section thereof, in particular with a fanning, a deflection, a deflection with length compensation by a dancer role, a detection of the bias of the Spulguts u via a suitable measuring device. ä.

According to Fig. 1 a deflection of the Spulguts 2 via a deflection 3, here a deflection roller 4. From this the Spulgut 2 reaches a Changierspulgutführer 5, which performs a traversing movement in a traversing direction 21, which is vertical to the plane according to Fig. 1 is oriented. Subsequently, a deflection of the Spulguts 2 by a pressure roller 6, by means of which then the Spulgut 2 is applied to the lateral surface of the coil 7 with a contact force. For the in Fig. 1 illustrated embodiment, the coil 7 is wound on a sleeve 8, which is offset by a spindle 9 in rotation. The longitudinal, movement or rotation axes of the guide roller 4, the pressure roller 6, the Coil 7, the sleeve 8 and the spindle 9 and the traversing direction 21 of the traversing yarn guide 5 are oriented parallel to each other. Notwithstanding the described embodiment, a drive of the coil 7 can not be done via a spindle, but via a driven drive roller. It is also possible that the coil 7 is wound directly on the spindle 9 without the interposition of the sleeve 8.

For the illustrated embodiment, the guide roller 4, the Changierspulgutführer 5 and the pressure roller 6 are held by a Spulgutleitwerk 10 while allowing a rotational movement of the guide roller 4 and pressure roller 6 and the traversing movement of the traversing. In order to allow the contact pressure of the pressure roller 6 to the coil 7 with a defined constant or variable contact pressure even with increasing diameter of the coil 7, the Spulgutleitwerk 10 is movably mounted in the radial direction to the spindle. For the illustrated embodiment, the Spulgutleitwerk 10 is pivoted about a pivot axis, which is vertical to the plane according to Fig. 1 is oriented. The specification of the contact pressure can be effected by the weight of the Spulgutleitwerks 10 or via a suitable actuator.

Fig. 2 shows in a highly schematic representation of the path of the Spulguts 2 between the deflection means 3 and the guide roller 4 and the traversing coil guide 5 for an embodiment of the invention. Here passes through between the guide roller 4 and the traversing 5, the Spulgut 2 a holding device 11. The holding device 11 is held stationary for the illustrated embodiment of the Spulgutleitwerk 10. The Spulgut 2 is passed during the actual winding process as possible without contact with this by the holding device 11. For this purpose, the winding material 2 enters the holding device 11 in the region of a guide member 12. The guide member 12 is formed as an open-edged slot 13 with an edge opening 14, which is arranged on the deflection roller 4 facing side of the holding device 11. From the slot 13 passes through the Spulgut 2 formed in the interior of the holding device 11 Spulgut-passage space 15. From the Spulgut-passage space 15, the Spulgut occurs on the the Changierspulgutführer 5 and the spindle 9 side facing by a Spulgut exit slot 16. For the in Fig. 2 The first embodiment shown is the Spulgut exit slot 16 open on both sides with edge openings 17, 18. The holding device 11 forms a receptacle 19 for a Spulgut suction gun, which in an insertion 20 in the receptacle 19 can be introduced. For the embodiment according to Fig. 2 is the holding device 11 with a profile with constant Cross-section formed, wherein the cross section may be referred to in a first approximation as C-shaped. Between the two end portions of the C-shaped cross section of the Spulgut output slot 16 is formed. The inner contours of the C-shaped cross-section bound the receptacle 19. The insertion direction 20 and the slot 13 and the Spulgut exit slot 16 are oriented parallel to the traversing direction 21 of the traversing yarn guide 5. The guide member 12 and the slot 13 and the Spulgut exit slot 16 each form an opening 22, 23 of the Spulgut-passage space 15. The holding device 11 has an opening 25 through which the Spulgut suction gun into the receptacle 19 of the holding device 11 in the insertion direction 20 can be introduced and an opposite opening 24. In the insertion 20 behind the holding device 11, but in alignment with the receptacle 19, a cutting device 26 is arranged, which is shown here in training with a cutting edge.

Fig. 3 and 4 show a spatial representation of a second embodiment of a holding device 11. According to their function and / or structural design corresponding o. Ä. Constructive details are marked with the same reference numerals. Here, the holding device 11 is formed with an example cast housing 27, which deviates from the embodiment according to Fig. 2 The housing 27 has a first approximation tube-like geometry with an extension in the form of a funnel 28 in the direction of the opening 25. In rough simplification, therefore, the receptacle 19 of the holding device 11 according to Fig. 3 and 4 Both the guide member 12 forming slot 13 and the Spulgut exit slot 16 are not open edge designed for this embodiment in the bottom portion 29, but rather edge-closed. While the slot 13 in the opening 25 facing the end region is also closed edge, the Spulgut exit slot 16 is open-edged with the edge opening 18 is formed. The holding device 11 according to Fig. 3 and 4 has a further slot 30, which is oriented transversely to the insertion direction 20, here in the circumferential direction of the housing 28. The slot 30 opens into an end region in the Spulgut exit slot 16 and in the other end in the slot 13. In a settlement of the housing 27 form the slots 13, 30 and the Spulgut exit slot 16 in rough simplification an H-shaped opening, wherein the Spulgut exit slot 16 and the slot 13 form vertical leg of the H and the slot 30 forms the horizontal leg of the H.

In the bottom region 29 facing the end portion of the receptacle 19, a sensor 31 is arranged, which passes through the housing 27 into the receptacle 19 for the illustrated embodiment. In this case, any type of sensor can be used, for example a mechanical switch actuated with the introduction of the winding material suction gun or a contactless sensor such as a Hall sensor, a reed contact or the like.

Furthermore, the cutting device 26 is integrated into the holding device 11 for the second embodiment of the holding device 11. Here, the cutting device 26 limits the Spulgut output slot 16 so that the Spulgut interacts with the cutting device 26 when this is forced along the Spulgut exit slot 16 in the direction of the bottom portion 29. For the illustrated embodiment, the cutting device 26 is a plate-like cutting element, which is screwed by a fastening screw from the outside in a position to the holding device 11, in which the periphery forming a cutting edge slightly covers the Spulgut exit slot 16 from the outside.

On the side facing away from the Changierspulgutführer 5 side of the holding device 11, the deflection means 3, here the guide roller 4 upstream, which is supported with a fixed predetermined axis of rotation 32 in the figures, not shown fasteners, support o. Ä. In the end region facing away from the opening 25 or in the bottom region 29, the housing 27 has suitable bores 33, via which the holding device can be coupled directly to the winding machine, in particular the Spulgutleitwerk 10 or coupled with the winding machine 1 with the interposition of other support elements. The coupling is made such that the axis of rotation 32 of the roller 4 is oriented so that from the lateral surface of the roller 4, the winding material through the slot 13, the Spulgut-passage space 15 and the Spulgut exit slot 16 without contact with the housing 28 to the traversing 5 can get. With the holes 33, a fastening element 41 of the holding device 11 is formed.

Fig. 5 schematically shows how the Spulgut 2 enters in a winder according to the invention without contact with the housing 27 in the region of the guide member 12, here the slot 13 in the Spulgut-passage chamber 15 and the holding device 11 leaves through the Spulgut exit slot 16 and rectilinear longitudinal axis as a result of the bias to the traversing 5 Wickierspulgutführer passes.

Fig. 6 shows the laying of the thread in the laying triangle 34 as a result of the traversing movement 21 of the Changierspulgutführers 5. For all positions of the Changierspulgutführers 5 the Spulgut 2 is passed without contact with the housing 27 through the slot 13 and the Spulgut exit slot 16, including the length of slot 13 and the Spulgut exit slot 16 is sized accordingly. In the middle position of the Spulguts this is the Spulgut in the slot 13 and the Spulgut exit slot 16 approximately at the place where opens into this slot 30. By contrast, for a deflection of the Changierspulgutführers 5 from this middle position, the winding material through the upper boundary of the slot 13 and the Spulgut exit slot 16 out. It can be seen in Fig. 6 likewise, that for the maximum deflection of the traversing yarn guide 5, the product 2 still has a distance 35 from the cutting edge of the cutting device 26.

Fig. 7 shows in a front view in viewing direction in the insertion direction 20, the holding device 11 with guide roller 4 and housing 27, wherein due to the edge opening 18, the Spulgut 2 can be seen in the Spulgut exit slot 16, while the entry of the Spulguts in the slot 13 in this view can be seen, since this slot 13 is closed at the edge.

• Für die Inbetriebnahme der Spulmaschine wird zunächst das Spulgut 2 durch die Haltevorrichtung 11 hindurchgeführt, nämlich durch den Schlitz 13, den Spulgut-Durchtrittsraum 15 sowie den Spulgut-Ausgangsschlitz 16. Hierzu wird das Spulgut 2 zunächst zur Anlage an das Umlenkmittel 3 bzw. die Umlenkrolle 4 gebracht und dann das Spulgut entweder für das Ausführungsbeispiel gemäß Fig. 2 von links durch die Randöffnungen 14, 17 in die Schlitze 13, 16 eingeführt oder für das Ausführungsbeispiel gemäß Fig. 3 und 4 von oben durch den Schlitz 30 in die Schlitze 13, 16 eingebracht. Dies kann bereits mit einer Spulgut-Saugpistole erfolgen. Dann wird das Spulgut 2 in an sich bekannter Weise dem Changierspulgutführer 5 und nachgeordneten Bauelementen zugeführt und einer Fangeinrichtung der Spindel 9 oder der Hülse 8 zugeführt oder manuell auf die Hülse aufgewickelt. Während des Wickelvorgangs der Spule 7 bewegt sich das Spulgut 2 in Längsrichtung der Schlitze 13, 16, ohne dass ein Kontakt oder eine Umlenkung durch das Gehäuse 27 der Haltevorrichtung 11 erfolgt. Ist die erste Spule 7a fertig gewickelt, wird ein Saugrohr 36 einer Spulgut-Saugpistole 44 in Einführrichtung 20 durch die Öffnung 25 in die Aufnahme 19 eingeführt, vgl. Fig. 8 . Das Saugrohr 36 trägt stirnseitig einen Saugstutzen 37, welcher eine Saugöffnung 38 ausbildet. Mit hinreichendem Eintritt des Saugstutzens 37 in die Aufnahme 19 kommt die Stirnseite 39 des Saugstutzens 37 zur Anlage an das Spulgut 2. Die weitere Bewegung der Spulgut-Saugpistole 44 in Einführrichtung 20 führt zu einer Umlenkung des Spulguts 2 und Mitnahme des Spulguts 2 in Richtung der Schneideinrichtung 26. Die Stirnseite 39 ist hier geeignet geformt und unter Umständen beschichtet, um eine gleitende weitere Bewegung des Spulguts 2 gegenüber der Stirnseite 39 zu ermöglichen. Schließlich wird das Spulgut 2 durch die Stirnseite 39 gegen die Schneidkante der Schneideinrichtung 26 gedrückt, womit ein Durchtrennen des Spulguts 2 erfolgt. Mit dem Durchtrennen kann das freiwerdende eine Ende des Spulguts 2 auf der weiterhin rotierenden Spule 7 aufgewickelt werden. Das andere Ende des Spulguts 2 überdeckt die Saugöffnung 38 des Saugstutzens 37, so dass mit dessen Freiwerden das zulaufende Spulgut 2 in den Saugstutzen 37 und das Saugrohr 36 eingesaugt wird. Die fertig gewickelte Spule 7a kann dann abgebremst werden und von der Spindel 9 entfernt werden und eine neue Hülse 8 wird auf die Spindel 9 aufgesteckt. Nun muss das Spulgut 2 über den Changierspulgutführer 5 der Fangeinrichtung der neuen Hülse 8 oder der Spindel 9 zugeführt werden, um einen Wickelvorgang für die nächste (zweite) Spule 7b zu ermöglichen. Hierzu wird die Spulgut-Saugpistole 44 aus der Aufnahme 19 entgegen der Einführrichtung 20 herausgezogen, was zur Folge hat, dass das Spulgut 2 ebenfalls durch die Öffnung 25 die Haltevorrichtung 11 verlässt. Das Spulgut 2 tritt dabei weiterhin von der Umlenkrolle 4 weiterhin durch den Schlitz 13 in die Haltevorrichtung ein, ohne dass eine Umlenkung des Spulguts 2 durch das Gehäuse 27 erfolgt (oder mit einer geringfügigen Umlenkung in dem der Öffnung 25 zugewandten Randbereich des Schlitzes 13). Ist die Spulgut-Saugpistole 44 aus der Haltevorrichtung 11 herausgezogen, kann diese frei bewegt werden. Da das Spulgut 2 in dem Schlitz 13 angeordnet ist, kann sich das Spulgut 2 nicht von der Umlenkrolle 4 lösen, so dass der Schlitz 13 ein eingangsseitiges Führungsorgan 12 für das Spulgut 2 bildet. Hierbei bildet die eine randseitige Begrenzung des Schlitzes 13 für die Ausführungsform gemäß Fig. 2 und bilden die beiden randseitigen Begrenzungen des Schlitzes 13 für die Ausführungsformen gemäß Fig. 3 und 4 seitliche Begrenzungen für eine eingangsseitige Bewegung des Spulguts 2, während die obere Begrenzung sowie die untere Begrenzung des Schlitzes 13 eingangsseitige Bewegungen des Spulguts 2 nach oben bzw. unten begrenzen. Die vorgenannte Führungswirkung ist für die Ausführungsform gemäß Fig. 3 und 4 unter Umständen eingeschränkt durch den Schlitz 30. Um hier einen unerwünschten Austritt des Spulguts 2 durch den Schlitz 30 zu vermeiden, kann der Schlitz 30, auch abweichend zu der Ausführungsform gemäß Fig. 3 und 4, an anderer Stelle angeordnet sein, beispielsweise in Richtung des Bodenbereichs 29 verlagert sein. Wird nun das Spulgut 2 in Richtung des Changierspulgutführers 5 und zu weiteren Bauelementen sowie letztendlich zu der Spindel 9 bzw. Hülse 8 geführt, kann das Spulgut 2 ausgangsseitig der Haltevorrichtung 11 in den Spulgut-Ausgangsschlitz 16 eintreten, so dass das Spulgut 2 je nach Ort der Saugöffnung 38 der Spulgut-Saugpistole 44 an unterschiedlichen Orten entlang des Spulgut-Ausgangsschlitzes 16 angeordnet ist. Wird die Saugöffnung 38 hierbei zu hoch oder zu niedrig gehalten, kann das Spulgut 2 zur Anlage an eine obere oder untere Begrenzung des Spulgut-Ausgangsschlitzes 16 kommen, wozu diese Begrenzungen geeignet abgerundet und ggf. mit einer entsprechenden Gleitbeschichtung ausgestattet sein können. Während der Zuführung des Spulguts 2 zu der neuen Hülse 8 gewährleistet somit die Führung des Spulguts 2 mittels des Führungsorgans 12 bzw. des Schlitzes 13 sowie des Spulgut-Ausgangsschlitzes 16, dass das Spulgut 2 weiterhin über das Umlenkmittel 3 oder die Umlenkrolle 4 läuft und sich nicht hiervon lösen kann. Auch stromaufwärts der Umlenkrolle 4 kann das Spulgut 2 durch die erfindungsgemäßen Maßnahmen weiterhin so verlaufen, wie dies während des eigentlichen Spulvorgangs der Fall ist. Ist das Spulgut 2 einer Fangeinrichtung von Spindel 9 oder Hülse 8 zugeführt, wird das Spulgut 2 manuell, beispielsweise mittels eines Messers oder einer Schere, zwischen Fangeinrichtung und Saugöffnung 38 durchtrennt, womit der eigentliche Spulvorgang für die zweite Spule 7b beginnen kann. Möglich ist aber auch, dass keine Fangeinrichtung vorgesehen ist. In diesem Fall wird das Spulgut manuell, unter Umständen unter Nutzung der Spulgut-Absaugpistole, mehrmals um die Hülse 8 gewickelt, womit hinreichende Reibung erzeugt wird, um den Wickelvorgang zu beginnen. Das derart aufgewickelte Ende des Spulguts wird dann durch das zulaufende Spulgut überwickelt und fixiert.

The operation of the winding machine 1 according to the invention with holding device 11 takes place as follows:

• For the commissioning of the winder, first the wadding material 2 is passed through the holding device 11, namely through the slot 13, the Spulgut-passage space 15 and the Spulgut output slot 16. For this purpose, the Spulgut 2 is initially for contact with the deflection 3 and der Umlenkrolle 4 brought and then the Spulgut either for the embodiment according to Fig. 2 from the left through the edge openings 14, 17 inserted into the slots 13, 16 or for the embodiment according to Fig. 3 and 4 introduced from above through the slot 30 in the slots 13, 16. This can already be done with a Spulgut suction gun. Then the Spulgut 2 is fed in a conventional manner the Changierspulgutführer 5 and downstream components and fed to a catching device of the spindle 9 or the sleeve 8 or manually wound onto the sleeve. During the winding process of the spool 7, the Spulgut 2 moves in the longitudinal direction of the slots 13, 16 without a contact or a deflection by the housing 27 of the holding device 11 takes place. If the first bobbin 7a is finished wound, a suction tube 36 of a bobbin suction gun 44 is inserted in the insertion direction 20 through the opening 25 into the receptacle 19, cf. Fig. 8 , The suction tube 36 carries the front side of a suction nozzle 37, which forms a suction opening 38. With sufficient entry of the Saugstutzens 37 in the receptacle 19 is the end face 39 of the suction nozzle 37 to rest on the Spulgut 2. The further movement of the Spulgut suction gun 44 in the insertion 20 leads to a deflection of the Spulguts 2 and entrainment of the Spulguts 2 in the direction of the cutting device 26. Die End face 39 is suitably shaped here and possibly coated in order to allow a sliding further movement of the Spulguts 2 with respect to the end face 39. Finally, the Spulgut 2 is pressed by the end face 39 against the cutting edge of the cutter 26, whereby a severing of the Spulguts 2 takes place. With the severing the released one end of the Spulguts 2 can be wound on the further rotating coil 7. The other end of the Spulguts 2 covers the suction opening 38 of the suction nozzle 37, so that with its release the incoming Spulgut 2 is sucked into the suction port 37 and the suction pipe 36. The finished wound coil 7a can then be braked and removed from the spindle 9 and a new sleeve 8 is attached to the spindle 9. Now the Spulgut 2 must be supplied via the traversing 5 Changierspulgutführer the catcher of the new sleeve 8 or the spindle 9 to allow a winding operation for the next (second) coil 7b. For this purpose, the Spulgut suction gun 44 is pulled out of the receptacle 19 opposite to the insertion direction 20, which has the consequence that the Spulgut 2 also leaves the holding device 11 through the opening 25. The Spulgut 2 continues to occur from the guide roller 4 continues through the slot 13 in the fixture, without that a deflection of the Spulguts 2 by the housing 27 takes place (or with a slight deflection in the opening 25 facing edge region of the slot 13). If the Spulgut suction gun 44 pulled out of the holder 11, this can be moved freely. Since the Spulgut 2 is arranged in the slot 13, the Spulgut 2 can not be detached from the deflection roller 4, so that the slot 13 forms an input-side guide member 12 for the Spulgut 2. Here, the one edge boundary of the slot 13 for the embodiment according to forms Fig. 2 and form the two edge boundaries of the slot 13 for the embodiments according to Fig. 3 and 4 lateral boundaries for an input-side movement of the Spulguts 2, while the upper limit and the lower limit of the slot 13 limit input-side movements of the Spulguts 2 up or down. The aforementioned guiding action is according to the embodiment Fig. 3 and 4 limited by the slot 30. In order to avoid an undesirable exit of the Spulguts 2 through the slot 30, the slot 30, also deviating from the embodiment according to Fig. 3 and 4 , be arranged elsewhere, for example, be displaced in the direction of the bottom portion 29. Now is the Spulgut 2 in the direction of the traversing yarn guide 5 and other components and ultimately too led the spindle 9 and sleeve 8, the Spulgut 2 on the output side of the holding device 11 in the Spulgut exit slot 16 occur, so that the Spulgut 2 depending on the location of the suction opening 38 of the Spulgut suction gun 44 at different locations along the Spulgut exit slot 16 is arranged. If the suction opening 38 in this case kept too high or too low, the Spulgut 2 can come to rest against an upper or lower boundary of the Spulgut exit slot 16, to which these limitations may be suitably rounded and optionally equipped with a corresponding slip coating. During the feeding of the Spulguts 2 to the new sleeve 8 thus ensures the leadership of the Spulguts 2 by means of the guide member 12 and the slot 13 and the Spulgut exit slot 16 that the Spulgut 2 continues to run over the deflection 3 or the guide roller 4 and can not solve this. Also upstream of the deflection roller 4, the Spulgut 2 by the inventive measures continue to run as it is the case during the actual winding process. Is the Spulgut 2 a catching device of spindle 9 or sleeve 8 fed, the Spulgut 2 is manually, for example by means of a knife or a pair of scissors, severed between catcher and suction port 38, whereby the actual winding process for the second coil 7b can begin. It is also possible that no catcher is provided. In this case, the Spulgut is manually, possibly using the Spulgut-suction, wound several times around the sleeve 8, whereby sufficient friction is generated to begin the winding process. The thus wound end of the Spulguts is then wrapped and fixed by the incoming Spulgut.

In a particular embodiment of the invention, the end face 39 of the suction nozzle 37 with adjacent thereto Spulgut 2 according to Fig. 8 pressed against a stopper member 40 to initiate the cutting operation by the cutter 26. This has the consequence that the friction acting on the Spulgut 2 between stop member 40 and end face 39 increases, which in turn has the consequence that increases the tension of the Spulguts 2 between the end face 39 and stop member 40 and the traversing 5. This increased tension has the consequence that the winding material 2 is pulled with a greater force against the cutting edge of the cutting device 26, whereby the severing is then caused.

The funnel-shaped extension of the housing 27 forms an insertion region 42 for the winding material suction gun.

In Fig. 1 a winder 1 is shown with only one winding station 43, where quite in a winder 1 and several winding stations can be operated in parallel.

It is possible that the holding device 11 according to the invention is used as an initial equipment for the winder 1 with their delivery to the customer. However, it is also possible that the holding device 11 according to the invention is marketed as a retrofit product for already previously distributed winding machines 1 and is used.

In the figures, the last deflection means 3, here the deflection roller 4, attached to the Spulgutleitwerk 10, which has the consequence that, regardless of the pivoting of the Spulgutleitwerks 10 during the winding process of the coil 7, the plane within which the Spulgut 2 in the fixture 11 performs an iridescent motion, does not change. But it is also possible that the holding device 11 upstream last deflection means 3, in particular a guide roller 4, not attached to the Spulgutleitwerk 10, but for example on a housing of the winder 1. This has the consequence that with the movement or pivoting of the Spulgut -Leitwerks 10, the plane within which the Spulgut 2 during the installation of the same changes, relative to the holding device 11 changes. This relative movement must possibly be taken into account by suitable design of the guide member 12 or the slot 13 and the Spulgut output slot 16, in particular by forming the slots 13, 16 with increased slot width.

It is possible to automate the method for operating the winder 1 during the bringing about the change. It is possible that the tension of the Spulguts 2 is detected. This first changes with the pressing of the end face 39 of the suction nozzle 37 to the Spulgut 2 due to the increased friction. A further increase in the friction can take place when the winding material 2 is pressed between the stop element 40 and the end face 39. On the other hand, the voltage drops in the Spulgut 2 from the same with the severing. These changes in the tension of the Spulguts 2 can be detected on the one hand by an upstream of the holding device 11 arranged measuring device, for example based on a dancer role. Alternatively or cumulatively possible is the detection of the voltage of the Spulguts 2 on the required drive power for the coil 7. With the monitoring of the voltage can be detected automatically by a control device that a severing of the Spulguts 2 is carried out, which with a time delay or a deceleration of Spool 7 and / or unlocking the sleeve 8 can be triggered by the spindle 9. additional can be evaluated, an output signal of the sensor 31, by means of which it is detected how far the suction nozzle 37 of the winding material suction gun 44 is inserted into the receptacle 19. It is also possible that with the detection by the sensor 31 that the Spulgut suction gun 44 is removed again after severing the Spulguts 2 from the receptacle 19, automated after the previous change of the sleeve 8 on the spindle 9, the sleeve 8 with the spindle 9 is locked and then rotated. In this case, initially a rotational speed for spindle 9 and sleeve 8 can be selected, which allows or simplifies the capture of the Spulguts 2, while subsequently a different drive speed is selected for the actual winding process.

• eine Beschleunigung des Wechsels,
• eine Vereinfachung des Wechselvorgangs und letztendlich eine Kostenreduzierung durch Reduzierung von Bedienfehlern und Störungen und/oder
• eine Zeit- und Materialersparnis infolge der Verkürzung der Absaugzeiten mit verlorenem Spulgut

erzielt werden.According to the invention, the severing of the Spulguts 2 can be done without a separately operated cutting instrument. The Spulgut suction gun 44 is placed during the change of the coil 7 against an empty sleeve 8 at a defined location in the holding device 11. According to the invention, the renewed placement of the Spulguts to the last, the holding device 11 upstream deflection means 3 omitted after a change. According to the invention

• an acceleration of the change,
• a simplification of the change process and ultimately a cost reduction by reducing operator errors and malfunctions and / or
• a time and material savings due to the shortening of the suction with lost Spulgut

A holding device 45 can provide both the holding device 11 and the last of these upstream deflection means 3 as a compact structural unit.

It is understood that in the context of the present invention with "slot" and "exit slot" any embodiment with rectilinear or curved longitudinal axis and the same or varying slot width is included.

It is also possible that in the receptacle 19 of the holding device 11, the Spulgut suction gun 44 rests locked or secured by friction.
