Definitions
- the invention relates to a stacker with which stack Stack layers, in particular from paper sheets or the like or can be piled up to make it cubic afterwards Remove blocks and pack them if necessary.
- the truck is conveniently located at the exit of a paper processing machine, whose cross cutters are the individual layers of one separates web material coming directly from a store, transferred into a flaky layer stream and so on hands over the stacker.
- EP 0 448 732 A1 describes a device according to the preamble of Claim 1 became known in the case of the bow on a table Formation of a stack can be collected. This happens between Stacking limits to remove the stack in two opposite directions can be folded up. The stack is pushed by sliders in the respective direction of removal, the are attached to chains running under the table and under the Table level can be pivoted. There must be separate ones here Stacking limits and sliders are provided and these must be can be controlled separately and coordinated.
- the invention has for its object a stacker to create the disadvantages of known training or the described type are avoided and especially with simple Structure and low tax expenditure for the movement sequences allows high working speed.
- the slider is immediately affected by such a stack limit formed so that it starts at the beginning of the stacking of the stack the edge surfaces of all stack layers and after finished Stacking the stack is only horizontal Needs to perform shifting movement.
- this limitation is expedient from their working situation can be lowered immediately down to below the stacking surface, so that it does not come into contact with the stack when it is moved.
- the Stack support on which the stack layers immediately and without Using a pallet can be piled up during the Operation, that is, from hanging up the bottom to hanging up the top sheet of a stack to be removed at a constant height lie. To form different heights, all you need is lateral stacking limits compared to the stacking support in height to be adjusted.
- the stacking station between two Abundern lies so that both face each other Stacking limits both provided as sliders, such as can also be optionally lowered in the manner described.
- the arrangement between two conveyors is also for other funding elements, such as those mentioned Conveyor tongs are suitable, as particularly short transfer or Result in sliding paths and to reach a more distant one
- the conveyor does not overflow a closer one with the stack must become.
- the stack support must be during of stacking are not continuously lowered, but the bottom of the stack can be at the height at which it when stacking the stack, remain until the Stack is passed to the conveyor.
- the two conveyors can be outside the stacking stations via S-shaped sections of curvature be closer to each other in the discharge direction, so that their ends then immediately next to each other lie and are so easily accessible or in the same packaging machine can flow.
- the packaging machine the stacks are completely wrapped in paper.
- the feed direction of the stack layers is expediently parallel to the transfer direction of the transfer conveyor, while the Discharge direction perpendicular to it, but also lies horizontally.
- the stacking station does not have to be interrupted Distance above the stack support and the finished stack an auxiliary device, such as a retainer and / or one Auxiliary pad provided, which is parallel to the feed and Transfer direction from outside the stack floor plan this can be driven and temporarily the further supplied stacked layers or which they in Feeder stops.
- the auxiliary member can be withdrawn be, the few, placed on it or on it jammed stacked layers as a flat stack stripped or again are fed and fall onto the stacking support. After that all further stack layers are successively in the Clearance above the stack from the feed conveyor, see above that they fall down onto the stack under weight can.
- the feed conveyor and the auxiliary links are for easy maintenance regardless of their location above the Path of movement of the stack in a maintenance position remote from it transferable, for example pivotable upwards or can be moved away from the side. So that the stack layers are congruent vibrating means are provided, which, for example, the pile support and the pile limits or the respective slider during the entire Layering process in vibration with an amplitude of move about a millimeter.
- the removal agent appropriately means to different friction values between the discharge support and the bottom of the stack generate or around these friction values over the contact width of the stack at different heights.
- the discharge pad is perforated and attached to an air conveyor be connected that adjoining width ranges independently of each other either with suction air or with compressed air be charged.
- a conveyor belt is provided, this is appropriate narrower than the stack and during the discharge movement the underside of the stack with suction air against the discharge support of this conveyor link, while laterally adjacent width areas of the stack lying on sliding surfaces run and their friction by applying the sliding bottom is reduced to a minimum with compressed air becomes.
- the stacker 1 has a stacking station 2, in which with an overlying feed conveyor 3, the stack layers 6 each other supplied and closed overlapping as a flaky layer flow a stack 7 can be piled up. After stacking up is the stack 7 with a transfer conveyor 60 on a Conveyor 4 and 5 transferred, which the stack of the Stacker 1 transported away.
- the stacking station 2 has a stationary, rigid table on the upper surface the bottom stack layer 6 is immediately deposited and on the lowest layer 6 when it is transferred to the conveyor 4 or 5 slides as well as on the top of the discharge support 9. These upper sides or support and sliding surfaces lie in a common, horizontal plane 10 Funding or transfer direction and to level 10 defines the Station 2 a middle level 11 and the conveyor 4 or 5 a central plane 12. At a distance above and parallel to Level 10, the feed conveyor 3 defines a feed level 13, in which the stacking layers 6 always at a distance above the Top of the stack 7 horizontally and perpendicular to the Arrive level 11, then be released by feeder 3 and sink to the top of the stack 7.
- the stacking station 2 forms a separate one for each stack 7 Stacking shaft 14, parallel to levels 10, 11 a plurality of separate shafts 14 side by side are arranged and from a common or separate Feeders 3 can be loaded, however, the stack 7 hand over a common conveyor 4.
- Any vertical Shaft 14 is limited on all four sides, namely with rigid shaft boundaries 15 to 18, of which the boundaries 15, 16 on both sides of the central plane 11 face each other while the other shaft boundaries 17, 18 face each other at right angles to it and are each formed by a thin, plate-shaped wall. Only one wall 18 separates adjacent shafts 14 or Stack 7 from each other.
- the shaft boundaries 15, 16 are by rod-shaped over the top of the pads 8, 9 after protruding arms formed above, which from this top go out or the stack support 8 in the area of passages 19 how to enforce elongated holes.
- Each limit 15 or 16 is formed by two arms lying next to each other at a distance, which are at a greater distance from each other than from the have adjacent wall 17 or 18. There is one for each arm separate, closely adapted passage 19 is provided, which is continuously limited over its entire scope and the Editions 8 and 9, respectively, completely penetrated.
- the lower ends of the limit arms 15, 16 are on one Carriage or carriage 20 arranged, which in the position 1 protruding upwards on both sides of level 11 Forms bearing columns 21, at the upper ends of the boundaries 15, 16 are pivotally mounted.
- the storage columns 21 are with Swing bearings 22 attached to that part of the slide, which on rails 23 perpendicular to plane 11, namely horizontally with a not shown Drive can be moved back and forth in directions 24, 25 is stored.
- the carriage 20 or the rail 23 is with a lifting device 26 perpendicular to the plane 10 adjustable, which increases the height of the level 10 after above parts of the limits 15, 16 continuously can change.
- Each boundary 15 or 16 forms one leg of one only two-armed angle lever, the other arm 27 below the Pads 8, 9 parallel to the direction 24, 25 to the opposite Limitation 16 or 15 is directed and at the still the transfer movement to be described is claimed only by train is. That removed from the associated boundary 15 or 16
- the end of the arm 27 is at the upper end of the associated column 21 pivoted.
- the columns 21 each carry one Shaft 28, which is rotatably mounted on the columns 21 and on which the angle arms 15, 27 and 16, 27 are attached, so that the respective limit 15 or 16 about the axis 29 of the associated shaft 28 over an arc angle of at most 40 ° is pivotable.
- each limitation is 15 or 16 completely pivotable below the support 8 or 9, as in Fig. 1 for the boundary 15 is indicated by dash-dotted lines.
- the axes 29 are further away from the central plane 11 as the shaft boundaries 15, 16, namely in plan view 2 outside the shaft, so that the arms 16, 27th can reach through between the arms 15, 27.
- the pivot axis 29 each on the other side of level 11 than the associated boundary 15 or 16, it could also be on the same side lie.
- the shafts 28, 29 are each not closer to one Actuator shown drive connected, so that they can be rotated independently.
- all boundaries 15 and 16 of all shafts 14 each have one common, continuous shaft 28 is provided, however it is also conceivable for the boundaries 15, 16 of each shaft 14 to provide separate shafts with separate servomotors swing them independently.
- the two axes 29 can be the same height or different.
- a limit 15 or 16 is pivoted down, then immediately lifts them off the corresponding stacking edge in one flat sheet, so that the shaft 14 on the associated Page is now open and the other limit 16 and 15 respectively can act as a slider 30.
- the carriage 20 will then 1 to the right in the direction 25, so that the arms 16 of the slide 30 initially only the stack 7 the edition 8, then on both editions 8, 9 and finally just slide on the pad 9 towards 25 until the stack 7 previously symmetrical to level 11 then lies symmetrically to level 12.
- the arms 16 of the slider run in the narrowly adjusted elongated holes or Passages 19 through which they are well guided, the Passages 19 beyond the area of the shaft 14 to range in the area of edition 9.
- the feed conveyor 3 has two in common on each stack layer 6 attacking conveyor links, namely an upper conveyor belt 31 and a conveyor 32 located immediately below that circulate endlessly via separate deflections 33, 34, 36 and with their mutually facing strands Limit conveyor gap 35 for the flaky layer flow 6.
- the foremost redirection closest to level 11 33 of the upper band 31 is closer to level 11 than the corresponding foremost deflection 34 of the lower belt 32, so that the upper band 31 the associated limit 16 and the Overhangs shaft 14, while the lower belt 32 only up to Shaft limitation 16 is sufficient.
- the stack layers 6 therefore occur in a downward curved trajectory from the conveyor gap 35 immediately above the shaft boundary 16 supported by the upper band 31 against upward movements and arrive in free flight until their leading ones stop Arch edges on the shaft boundary 15, then at the same time their trailing sheet edges from the conveyor gap 35 are free, so that the stacking layer 6 as a whole down can sink.
- the leading sheet edge of the one above it Stack layer 6 is opposite to that of the one below Stack position set back so that the bottom one always comes first Stack layer 6 is completely released from the feed conveyor 3 and as Single sheet can sink onto the stack 7. Meanwhile the edition 8 and the limits 15 to 18 are continuous held in shaking movements and thereby the layers 6 in the stack 7 congruent to each other and spread out.
- the arches 6 are aligned at all limits 15 to 18.
- Each stack layer 6 can also consist of several, e.g. at least four or five, congruently one on top of the other or single sheets cut together on top of one another exist and so form a thin stack package.
- the stack support 8 and the arms 15, 27 and 16, 27 are Non-destructively exchangeable, which means that the Stacker 1 to different formats or sizes of Stacking layers 6 can be converted.
- the arms 27 can be on the shafts 29 continuously adjustable and fixable be arranged.
- the shaft boundaries 17, 18 are also can be exchanged non-destructively and are completely in place free on the top of the pad 8, opposite which it are clamped with screws or the like.
- the feed conveyor 3 is pivotable upwards so that it is in Top view is outside the shaft 14. To this end is the discharge end of the feed conveyor 3 with a bearing 37 pivoted, the axis of one of the deflections 36, namely a return deflection of the lower belt 32 can.
- the swivel direction is indicated by arrow 38 while the feed direction is indicated by arrow 39.
- the upper limit formed by the upper band 31 Conveying column 35 lies in the feed plane 13.
- auxiliary device 40, 40 At the end of the stacking of a stack 7 and before lowering the boundary 15 is an auxiliary device 40, 40 ' preventing further stacking of layers 6 on the stack 7, although the feed conveyor 3 continues to run.
- the auxiliary device 40 is always at a distance above of the stack 7 lying and therefore not in with this Touching auxiliary pad 41, 32 that immediately above the upper ends of the shaft boundaries 15, 16 and below the upper edges of the boundaries 17, 18 with lateral distance between them is such that their support level 46 permanently below or in the conveyor level 13 and the upper edges of the walls 17, 18, but slightly lies above the upper ends of the boundaries 15, 16.
- the Auxiliary pad 41, 32 lies in the direction 24, 25, 39, namely seen at right angles to levels 11, 12, completely between the limiting arms 15, 16 so that they are also below from their upper ends and over the shaft 14 could be moved.
- the auxiliary pad 41 is made with a carriage or sled 42 1 or 4 against direction 39 in the direction of 47 linearly into the working position according to the Figures 5 to 7 can be transferred in which they are above the shaft 14 or the stack 7 is approximately and with its free end extends to the level of the shaft boundary 16.
- a carriage 43 is in and against the carriage 42
- Direction 47 motor-driven on which the auxiliary support 41 with a slide 44 parallel to the Levels 10 to 13, 46, i.e. perpendicular to directions 24, 25, 39, 47 continuously adjustable and fixable is. This allows each auxiliary pad 41 to be independent of all remaining precisely adjusted to the associated shaft 14 in the event of a change to another format the stacking layers 6.
- All auxiliary supports 41 for all shafts 14 can be in the direction 47 adjustable together, e.g. on a common cross member 43 may be arranged, but is also an embodiment conceivable, in which the auxiliary support 41 for each shaft 14 regardless of all others in the working position and back to the rest position with a separate drive is transferable.
- Each auxiliary pad 41 has only two in Spaced fork-shaped fork arms 45 on, which are tapered at their front ends, in particular on the top and on the outer side flank.
- the Auxiliary pad 41 is suitably symmetrical to that Middle plane 48 of the associated shaft 14, which is rectangular to levels 10 to 13, 46 and parallel to Directions 24, 25, 39, 47 and boundaries 17, 18 lies.
- each Limitation 49 can be continuously through one over all stations 2 continuous component, such as a web, which is lower than the upper ends of the angle legs 15, 16 enough and comb-like with a tight for each angle leg adapted passage is provided in the form of an opening.
- layers 6 are also higher than the limits 15, 16, e.g. arrive on or at the auxiliary member 41, 41 ', immediately aligned with the limits 49.
- This support 54 can by a bow catcher 50 formed between two End positions with a shaft 51 can be pivoted about an axis 52 is stored, which is parallel to levels 10 to 13, 46 and perpendicular to directions 24, 25, 39, 47.
- a bow catcher 50 needs one end position to the other much less time and a smaller way than that Auxiliary pad 41 for its movement from the rest position according to Fig. 1 in the working position according to Figures 5 to 7.
- the Bow catcher 50 has an angle arm with a tangential to Shaft 51 hanging on this adjoining and one at right angles leg lying as a support finger 54, which directed against the mouth of the feed conveyor 3 and in side view is tapered.
- the finger 54 protrudes obliquely at an acute angle up against level 13 and away from level 10 while he in the working position according to Figures 3 and 5 to 7 with his Top extends to level 46.
- the finger 54 is much shorter than the fork rods 45 and over less than a fifth of the distance between the boundaries 15, 16 via the associated limit 15.
- the finger 54 fits tightly in the gap 53 between the support arms 45, so that despite its length it is good against lateral movements are slidably supported on the finger 54, but in Rest position must not be in engagement with the finger 54.
- the second or tangential leg forms in the working position the limitation 49 in the area of a closely matched gap penetrating bow catcher 50 a continuous sequel the associated limit 15, 49.
- the shaft 51, the for each station 2 carries a catcher 50, with a suitable, not shown control motor driven. Similar, each separate, control motors are also for the feed conveyor 3, each of the discharge conveyor 4, the carriage 20, the lifting device 26, each of the shafts 28 and the auxiliary support 41 is provided, with each pair of these Drives mechanically and / or electronically generated movements can be synchronized.
- the fingers 41, 54 opposite limit 49 can be tangential to the Connect the front of the deflector 34.
- All auxiliary links 41, 41 '54 are common or independent of each other in parallel infinitely adjustable to levels 10 to 13, 46, e.g. on the carrier 43 or on the shaft 51.
- FIG Has stop or retainer 41 ' is instead of or in addition to the device 40 a device 40 'is provided according to FIG Has stop or retainer 41 '. With him, the Layers 6 in the conveyor 3 before reaching the roller 34 and stopped immediately adjacent by the front stop, although the conveyor 3 continues to run.
- the Stop 41 ' stands over the end of one leg Angle lever 42 'perpendicular to the plane 13 in front. Whose other leg is attached to the adjusting head 44 'and with the Cross shaft 43 'pivotable by motor.
- the stop 41 ' engages downstream of the shaft 43 'between the adjacent conveyor sections of the band 31 through, so that its lower longitudinal edge slides approximately on the top of the shingled stream and its next and all other leaves on the Front edge locks. The leaves below it are further promoted to stack 7.
- the roller 33 can at least or approximately reach to the middle between the surfaces 15, 16 and deeper than the roller 34 lie, so that the belt 31 under pressure the roller 34 or the belt 32 running over it at an obtuse angle is angled downwards.
- the tape 32 has the same Conveyor width more individual belts next to each other than the band 31, between the larger gaps of the Stop 41 'e.g. reaches through as a comb so that the respective Stop fingers either between two bands 32 or lies on a tape 32.
- Upstream of the stop 41 'and immediately behind the forming flat stacks are means 50 'for spreading the Bands 31, 32 provided transversely to level 13 so that a continuously to redirect 34 or one upstream wedge gap that closes at an acute angle 35 'results. In it, the sheets 6 are pushed together collected, the chamber 35 'with the increase the number of sheets can steadily increase.
- the facility 50 ' has two adjacent deflections 54' and in the middle plane between these and further away from the belt 32 a further deflection 51 '.
- Belt 32 runs first over the first, downstream deflection 54 ', then over the Deflection 51 'and again via the second deflection 54'. Both Deflections 54 'close in the spread position according to FIG.
- rollers 54 ', 51' are on one common carrier arranged around one to level 13 parallel transverse axis controlled by motor and electronically is pivotable.
- the gap 35 ' is opened at the same time, when the correspondingly controlled finger 41 'in the stop position decreases.
- the band gap can following the first deflection 54 'upstream in a wedge shape be expanded to include the incoming leaves or to be able to introduce the shingled stream like a funnel.
- the Swivel axis of the roller carrier can be in the axis of each of the two deflections 54 'or between them, depending on whether the first deflection in the spread position against the belt 31 or this should be lifted or not.
- All movable parts of the device are on a base 55, e.g. a device frame, arranged, the side cheeks 56, on which the lifting device 26, the deflections 36, the bearing 37, the rails for the carriage 42, 43 and the shaft 51 are mounted or fastened.
- the rails of the carriage 52 and the bearings for the shaft 51 can movably mounted on the base 55 in a maintenance position in which they are further away from station 2 and release the top of the associated conveyor 4. For example, can this maintenance position according to FIG. 1 against the direction 47 be shifted outwards on the right. In the working position the devices 40, 50 are spaced above of the discharge conveyor 4, while the feed conveyor 3 is approximately the same Distance is above the feed conveyor 5.
- each conveyor 4 or 5 has a revolving conveyor belt 57
- the longitudinal median plane according to Figures 1 and 4 to 7 with the associated level 12 coincide or according to FIG. 2 in contrast, asymmetrically further away from station 2 can lie.
- On both sides to the upper run of the motor driven conveyor belt 57 close sliding tables 58, 59 immediately on, just like the conveyor belt 57 of perforations enforced and independent of each other on suction and Pressure medium, namely on pneumatic supply lines are connected via control means such as valves.
- control means such as valves.
- the stacking device 1 works as follows:
- the shaft 14 is located the limits 15, 16 in the stacking position, the Auxiliary pad 41 withdrawn and the catching pad 54 obliquely are set upwards.
- the feed conveyor 3 leads one stack layer 6 after the other of the edition 8 or Top of the stack 7 so that this never the top End of the limits 15 to 18 reached.
- the catch pad 54 pivots down less than 90 ° or 45 ° while simultaneously the movement of the auxiliary support 41 in the direction 47 begins and continues until it approaches approximately opposite boundary 16, 49 is sufficient.
- the further supplied stack layers 6 are now on the Auxiliary pad 41, 54 filed.
- the conveyor belt 57 is switched to suction, so that the bottom of the stack 7 adheres firmly to it while the two table surfaces 58, 59 continue to use compressed air are controlled to minimize sliding friction.
- the Conveyor belt 57 is then 61 in one of the two directions driven and thereby the stack 7 from the device 1st conveyed away.
- the car 20 begins in the opposite direction to 24 to to move back to the stacking position upon reaching it the limit 15 in turn begins upwards in the shaft position to pan.
- the layers 6 with continuous Speed continuously on the auxiliary support 41, 54 conveyed.
- the auxiliary pad 41 begins to withdraw, so that the stack layers 6 at the limit 16 first and last at the limit 15 under their weight the edition 8 decrease.
- the finger becomes 54 pivoted up again, the associated marginal zones the layer 6 under their curvature deformation over the free end of the finger 54 slide down.
