Cl. 24256 16 Claims ABSTRACT OF THE DISCLOSURE A device or apparatus having means for controllably winding a web material being processed and having means for cutting and automatically starting a new roll to wind the web material without the necessity of interrupting the feeding of the web material from its source.

BACKGROUND OF THE INVENTION Apparatus or devices are known which will provide means for cutting a web material as it is receive-d from a source but such devices do not provide for the automatic delivery and positioning of an element for winding the web material after it is cut without the necessity of stopping the feed thereof so as to permit the removal of the wound web material from the apparatus while starting a new roll.

The devices presently used, principally in the textile industry are expensive to manufacture, difiicult to employ and generally require considerable personnel to operate. Further, the interruption of the feed of the textile material as it is being processed through a high temperature treating zone causes damage to the material within the zone due to extended exposure to high temperature, Due to the time required to cut the material, complete and remove the wound roll and to start a new roll, these procedures are inefficient in operation and increase the cost for treating the textile material.

The apparatus of this invention overcomes the many disadvantages of the devices presently used in the textile industry and other industries employing continuous feed of web material.

The present device allows for the continuous feed of the web material from its source without the interruption of any of the machinery for treating or processing the material while being wound on a core rod or tube. The device is relatively inexpensive to manufacture, employs a novel means for feeding a new core bar onto the traveling web material and a novel means for cutting the material so that the cut end will automatically start to wind on a new core bar thereby allowing for the removal or dofling of the wound material from the device without interruption of the web material from its feed source. Thus, damage to the treated web material is obviated and maximum efficiency is achieved.

SUMMARY OF THE INVENTION My invention generally contemplates a new method and apparatus for continuously winding and dofiing web material while providing means for cutting the material and starting a new roll without interrupting the feed of the web material from its source.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 illustrates the assembly of the apparatus in which the web material, for example textile material, is received from a'feed source, not shown, onto the apparatus with the material being transported across the winding rolls prior to its completion.

For clarity the following description of the figures will describe the various sub-assemblies which comprise my improved apparatus for continuously winding, cutting and removing web material from the apparatus without the interruption of the feeding of the web material from its feed source.

The apparatus comprises the following sub-assemblies:

(a) The winding assembly 12 illustrated most clearly in FIG. 2;

(b) The shifting assembly 14 for moving the material being wound from one position to another on the winding assembly 12 shown most clearly in FIG. 3;

(c) The knife cutting assembly 16 shown most clearly in FIGS. 1, 2, 5 and 6; and

(d) The core bar feeding assembly 18 shown most clearly in FIGS. 1 and 4.

The winding assembly 12 comprises a plurality of rolls suitably mounted for rotation on a frame, not shown. The winding rolls preferably comprise four rolls 20, 21, 22 and 23, each roll being similar in construction and having center shaft assemblies 24, 25, 26 and 27 mounted at each end of a roll, as seen at roll 20. The outer shell 28 of each roll is rigidly mounted to the center shaft assembly by end plates 29 so that the shell of each roll rotates with its respective shaft. The shell of the roll may be made of a different material than the shaft, such as a light weight material, for example, synthetic rubber, synthetic elastomeric materials, such as polyamide, or the like. As illustrated in FIG. 2, shell 28 is mounted on respective shafts 24, 25, 26 and 27 by closed end members 29 so that a hollow annular space is provided between the inner portion of shell 28 and the respective shaft assemblies. It is obvious that the construction of the rolls may vary Wide- 1y, for example, where the rolls are not excessive in length they may be made of the same material as the shaft and may be solid. Where the rolls are excessively long for handling extreme widths of web material the rolls may be made of a material considerably lighter than the material forming the shaft so that the rolls when mounted on the apparatus will not bend or otherwise sag due to the excessive weight of the roll. The respective shafts are mounted for rotation on the apparatus frame employing bearing mounts, not shown, so that the shafts are journaled in the bearing mounts for rotation therein. The rolls are spaced from each other a sufficient disance substantially equal to or less than the diameter of the core bar 2 which is employed for winding the material therearound and which will be discussed more fully hereinafter. The chain and sprocket assembly coupled to roll 23, as seen in FIG. 2, provides drive means for roll 23. Rolls 20, 21, 22 and 23 are coupled by suitable chain and sprocket assemblies as shown in dotted lines in FIG. 2 such that all of the rolls will rotate at substantially the same speed and in the same direction.

Shifting assembly 14 is mounted on the apparatus so as to be movable a spaced distance along the upper surface of winding assembly 12 for moving the core bar 2 from its initial winding position to its final position on winding assembly 12 after the completion of the winding operation. The shifting assembly comprises a pair of racks 40 mounted on each side of the frame for the apparatus, not shown, and movable parallel to Winding assembly 12 in rack housing 42. Racks 40 are driven by a suitable gear or gears, not shown, mounted on shaft 44 in housing 42. Shaft 44 has one end extending from housing 42 and has mounted thereon chain sprocket 46. Shaft 50 is disposed beneath the winding assembly and extends across the width of the frame so that its end portions extend beyond shells 28 of the winding assembly and is mounted for rotation on the apparatus frame by a plurality of bearing assemblies, not shown. Chain sprockets 52 are mounted at each end of shaft 50. Endless chain 48 is mounted around chain sprockets 46 and 52 so that when shaft 50 is rotated sprockets 46 and 52 will rotate and thereby cause the transverse movement of racks 40 either in a forward or backward direction depending upon the rotation of shaft 50. Drive means 54 comprises a reversible electric motor 56 having a driving shaft extending therefrom, not shown, with the end of the shaft mounted to gear box assembly 58. Electrically operated over-riding clutch assembly 64 is mounted on drive shaft 60 between the ends thereof. Drive shaft 60 is mounted for rotation with one end mounted to gear box assembly 58 and its other end mounted to bearing assembly 59. Mounted on shaft 60 is drive sprocket 62. Shaft 66, which is mounted for rotation in bearing housings 68, has mounted thereon a second drive sprocket 70 with chain 72 mounted around sprockets 62 and 70 for rotating shaft 66. A pair of drive sprockets 72 and 76 are mounted respectively on shafts 66 and 50 with chain 78 mounted therearound for rotating shaft 50. An' electrically operated brake assembly 80 is mounted on shaft 50 for controlling the movement of shifting assembly 14. Electric motor 56 is of the reversible type so that upon the proper signal the rotation of the drive assembly may reverse the direction of movement of racks 40 either in a forward or backward direction as required. Over-riding clutch 64 is employed to prevent excessive strains and stresses on the gears in gear box assembly 58 and motor 56 when the electrically operated brake 80 is in a braking position. Racks 40 are provided with leading and trailing ends 41 and 43. Adjacent the leading end 41 of rack 40 is mounted core bar retaining housing 45 for positioning a core bar, not shown, therebetween so that when rack 40 is driven in a forward direction the core bar will be traversed along the winding assembly. The core bar assembly will be described in further detail hereinafter.

Knife assembly 16 is pneumatically driven and is actuated by electrically operated valves. Knife assembly 16 comprises an endless cutting blade or knife 90 which is mounted for rotation on driven pulleys 92 by shaft or spindle 94. Shaft 94 is mounted for rotation on a supporti g m 6 and ex ends th reth sus t en si ea t e pulley 92 and the other end mounting pulley 98. Electric motor having shaft 102 extending therefrom has mounted at its end pulley 104 so that belt 106 may be mounted around pulleys 104 and 98 for rotating knife 90 around pulleys 92. Shaft 108 is mounted for rotation in a pair of bearing housings 109 and has mounted thereon motor mounting plate 110 for pivotally mounting motor 100. Supporting arm 96 is pivotally mounted on shaft 108 so that motor 100 and cutting knife 90 will rotate in an arcuate direction between rolls 21 and 22 when supporting arm 96 is moved in an upward direction. Shaft 112 is mounted for rotation on the apparatus frame, not shown, and extends beneath the winding assembly transversely of the apparatus. At each end of shaft 112 mechanical linkage for raising and lowering the cutting knife 90 is provided. A first linkage or rod 114 is mounted on shaft 112 at one end 115 so as to rotate therewith. Pivotally connected between supporting arm 96 and the other end 116 of rod 114 is a second linkage 117 which is pivotally mounted at its ends 118 and 119 by pins 120 and 121. Mounted on each side of apparatus frame are pneumatic cylinder assemblies 122. Piston cylinders 126 are pivotally mounted on block 128 at one end thereof by pin 130. Piston rods 132 which extend from the other end of cylinders 126 are pivotally mounted by pins 134 on the under side of supporting arm 96. Thus as fluid enters cylinders 126 piston rods 132 are extended in an outward. direction so that supporting arm 96 is moved upwardly in the direction of the knife shown in phantom in FIG. 5 with mechanical linkage members 114 and 117 pivoting so as to form a substantially straight line.

Knife guide 136 is made of a plastic material and has a slot or opening formed along the longitudinal axis of the guide having a depth substantially equal to the width of the cutting blade 90 so that only the cutting edge 91 of knife 90 extends above the knife guide. Knife guide 136 is mounted on supporting arm 96 at each end'thereof by mounting bracket 138. A second knife guide 136 is mounted on the other side of knife'90 in a similar manner and having a similar configuration. Knife guide 136 prevents knife 90 from vibrating in a sinuous manner between pulleys 92 on which the knife is mounted for rotation. The cutting edge 91 of knife 90 is scalloped and is best illustrated in FIG. 9 which shows the points 93 of cutting edge 91 extending through web material 1. Thus as the cutting assembly moves arcuately upwardly, as illustrated in FIG. 5 in phantom, points 93 of cutting edge 91 pass through web 1 in the direction of the arrow as shown in FIG. 9. Since knife 90 is rotating in the direction of the arrow as seen in FIG. 9, the web material is out throughout its width since substantially all of the points of the cutting edge pass through the web material substantially simultaneously. The cutting action therefore is one of penetration and cutting in a vertical direction and cutting in a transverse direction for a distance of approximately one-half inch. Since knife 90 extends across the entire widthof the web material the knife or effective cutting edge is a plurality of knives which are continuous and are defined between points 93 of the cutting edge 91. Knife 90 is an endless cutting band and therefore the width of the material is not a limiting factor in cutting the web material 1 since the effective cutting stroke of knife 90 is approximately one-half inch. Knife 90 is rotated at a relatively high speed so that the time required to cut the one-half inch of material is substantially instantaneous thereby effecting the cutting of the web material in a substantially straight line.

Core bar feeding assembly is generally illustrated in FIG. 1 with detailed views in FIGS. 3 and 4 showing various components and operation of the assembly. Side panels 140 are mounted on each side of apparatus 10 'ad-. jacent the ends of the center shafts of the winding rolls, A core ba chut 142 which defi e a s b t nt a y te path illustrated in dotted lines in FIG. 1 is mounted on the inner surface of panel 140 so that the discharge end is positioned over the center line between winding rolls 20 and 21. A pneumatic-ally operated valve 144 is mounted to a piston cylinder 146 having fluid inlet and outlet openings 147 and 148. Piston rod 149 is pivotally connected at its outer end to plate 150. Plate 150 is mounted to a rotating shaft 152 and mounted thereon is cam 154 shown in dotted lines with a core bar being held by the ridge of the cam extending into the'chute 140 as seen in dotted lines in FIG. 1. Pneumatic valve 144 is connected to cylinder 146 by flexible hoses 155 and 156. When pneumatic valve 144 is electrically actuated pneumatic fluid is caused to enter cylinder 146 thereby extending piston rod 149 in an outward direction. This causes plate 150 to move arcuately outwardly and thereby rotate cam 154 so as to release core bar 2 being held by cam 50 to move or roll down chute 142. Mounted on core bar housing 45 is a vertically extending rod or bar 157 which extends to a point which intercepts chute 142 at its upper end. Thus when core bar 2 is released by cam 154 core bar 2 will roll down the chute until it is stopped by vertical bar 157. As shifting assembly 14 is moved to the start position as shown in FIG. 1 so that core bar housing 45 is positioned below the exit point of chute 142 core bar 2 is controlled during its descent along chute 142 at a relatively slow rate. When core bar housing 45 is at the rest position vertical rod 157 releases core bar 2 so that it contacts the pneumatic core bar positioning device 158 as seen in FIG 4. This device comprises a substantially horizontally extending bar 159 which is rigidly mounted on a rotatable shaft 160. Also mounted on shaft 160 is a second member 162 which is pivotally mounted to an air cylinder assembly 163. The weight of core bar 2 causes horizontal rod 159 to move in a downward direction as shown by the arrow in FIG. 5 and into core bar retaining housing 45 mounted on shifting assembly 14. Due to the weight of core bar 2 air or other pneumatic fluid is expelled from the air cylinder assembly 163. Rod 159 continues in a downward direction until core bar 2 is dropped onto core bar release pin 164 which is pneumatically operated and electrically actuated. When core bare 2 contacts core bar release pin 164, core bar 2 is in position for starting a newroll of web material after the web material is cut by the knife assembly.

Shifting assembly 14 is in the form of a channel similar in design to chute 142. A shifter door 166 forms one wall of the channel at the forward end of core bar hous ing 45 and is pivot-ally mounted .at its upper end. Mounted on its outer face and extending upwardly is bar 168 having wheel 170 mounted at its outer end. When the core bar housing is positioned over the center line between rolls 20 and 21 shifter door 166 is closed and held in that position by a fixed track 172 as seen in FIG. 1. When shifting assembly 14 is moved across the winding assembly 12 shifter door 166 is held closed by fixed track 172. As core bar housing 45 moves past roll 21 to approximately the center line between rolls 22 and 23 of winding assembly 12, track 174 which is pivotally mounted on rotatable shaft 176 pivots upwardly as shown in phantom in FIG. 1 so that fixed track 172 is separated from movable member 178. Shifter door 166 remains closed since whee-l 170 remains in contact with movable member 178. When shifting assembly 14 begins its backward movement to the rest or start position, as seen in FIG. 1, wheel 170 disengages from moveable member 178 and does not contact any other surface so as to permit shifter door 166 to pivot outwardly so as to release core bar 2 to cause the same to fall over the material web between rollers 20 and 21 The weight of the core bar will cause the material web to sag between rollers 21 and 22 and after the web material is severed by knife 90, the rotation of rollers 21 and 22 will cause the new leading edge of the web material to wind about the new core bar. The web material will continue to be wound between driven winding rolls 22 and 23. As core bar housing 45 passes onto track 172, wheel of shifter door 166 will contact the surface of fixed track 172 so as to close shifter door 166. Thus, by employing pivotally mounted track 174 means are provided for opening shifter door 166 which is pivotally mounted at one end and is moved to an open position by a spring-loaded hinge. Further, by employing pivotal track 174 means are provided for expanding the width of the roll of web material to a greater diameter than the distance between fixed track 172 and the upper surface of the winding rolls. Pivotal track 174 is mounted on rotatable shaft 176 at one end thereof. Also, pivotal arm 180 is mounted on rotatable shaft 176 at its inner end and is pivotally mounted to piston rod 181 at its outer end with piston rod 181 being disposed in piston cylinder 182. Pivotal track 174 is pneumatically controlled by piston assembly through pneumatic valve 184 which is electrically actuated. When shifting assembly 14 is at the rest or start position, i.e., in which core bar housing 45 is disposed over the center line between rolls 20 and 21, the apparatus is set or has completed its cycle for receiving the next core bar which has been positioned on ,core bar releasing pin 164.

FIG. 7 illustrates the pneumatic system for actuating the knife and core bar assemblies, in which air or other gasses may be used, air being less expensive is preferred. Air is supplied to the device through air supply line from a source not shown. Air supply line 190 is connected to an electrically operated four-way valve assembly 191 by any suitable coupling means. Flexible tube 192 connects air supply line 190 to the knife cutting assembly 16. Air passing through valve assembly 191 is conducted through pneumatic tube 193, through flexible air inlet tubes 194 to the inlet opening 195 of cylinders 126 of the knife cutting assembly. Thus, when electrical solenoids 196 are energized valve assembly 191 is opened to permit air to pass into cylinder 126. When piston rod 132 has been extended to full stroke, knife 90 will pass through web 1 and will immediately start in a downward movement by expelling air through cylinder 126 through flexible conduit 198, then through tube 199 and finally through exhaust opening 200. Air is supplied to the core feeding assembly which is controlled by the various pneumatic valves through flexible tube 202 which is connected to tube 204. Thus there is a constant air pressure maintained in line or tube 204 during operation of the apparatus. The various pneumatic valves and electrical solenoids which operate the various movements of the core bar and shifting assemblies operate independently through their own valves.

In FIG. 1 penumatic valve 206 supplies the necessary air pressure for operating the shifter release pin 164 when electrically actuated. Pneumatic valve 208 operates the core bar lowering assembly when electrically; pneumatic valve 184 actuates the shifter door locking assembly and pneumatic valve 144 operates the core bar release mechanism.

FIG. '8 illustrates the electrical schematic diagram for the device when the web is about to be cut.

When the roll of web material has reached the desired size or diameter and the shifting assembly 14 is in the start or rest position as seen in FIG. 1, limit switches LS7 and LS-2 are closed and LS8 is open. In this connection, limit switch LS7 is only closed when shifting assembly 14 is in the start or rest position. If shifting assembly 14 is not in the rest position, the knife cutting assembly cannot operate. Knife cutting assembly 16 is energized by pushing button PB1. Prior to energizing the knife cutting assembly relays shifter forward (SF), shifter backward (SB) and (KD) are deenergized. Theknife motor 100 starts, relays knife up (KU) and time delay relay (TDR) are energized but knife assembly 16 cannot move up to cut the web material until relay (TDR) times out and solenoid 196 on pneumatic valve assembly 191 is energized. After relay (TDR) times out, the cutting assembly swings arcuately upwardly between winding rolls 21 and 22 toward web 1. However, prior to cutting web 1 limit switch LS27 is closed energizing the solenoids to withdraw the core bar release pins 164 to drop core bar 2 onto web 1 producing tension on the web as illustrated in FIG. 5 so that knife blade 90- will penetrate and sever or cut web 1 as illustrated in FIG. 9. In this connection, it has been found that the timed sequence for dropping core bar 2 onto web 1 occurs to prior to knife 90 contracting Web 1 but is substantially instantaneous; that is, the time lapse between the dropping of core bar 2 and the cutting of web 1 occurs within the fraction of a second. After web 1 has been cut, limit switch LS-24 remains closed and holds relay (9SMR) energized so that core bar release pins 164 are held in the withdrawn position until shifting assembly 14 has moved in the direction of the dotted lines shown in 'FIG. 1. That is, core bar retaining housing 45 must pass at least to the center line of roll 21 before relay (SMR) is deenergized so that core bar release pins 164 are returned to their extended position. As soon as knife cutting assembly 16 has passed through web 1 at the end of its upward stroke, limit switch LS-8 is closed energizing the knife down relay (KD) so that the knife cutting assembly will return to its rest position as shown in FIG. 1. When relay (KD) is energized limit switch LS-3 is opened deenergizing relays (KU) and (BC) to stop motor 100 and return the knife cutting assembly to the down" position.

At the time web 1 is cut or severed, core bar 2 drops between winding rolls 20 and 21 and immediately a new roll of web material is winding around core bar 2 and the finished roll of web material is resting on revolving rolls 22 and 23 and the finished roll is ready to be dotted and removed to its place of storage or its next sequence of operation for treating the material.

With the cutting assembly in the rest position, that is, with the knife in the down position, limit switch LS-16 is closed and limit switch LS2 is opened. With the shifting assembly at its raised or start position limit switches LS29, LS7, LS- and LS13 are closed and limit switch LS17 is opened. In order to transfer or move the roll of web material being formed between rolls 20 and 21 button (PB-2) is pressed to energize relay (SB) and instantly relay (SB-j) contacts are opened releasing the magnetic brake (MB). Relay (SB-k) is closed to magnetize overriding clutch 64. Also relay (SBZ) is closed and the magnetic brake (MB) contactor energizes the motor to revolve in the proper rotation. As shifting assembly 14 moves away from its rest position limit switch LS31 is closed and energizes the solenoid to bring the core lowering arm assemby 158 to the UP position as seen in FIG. 5. Also pivotally mounted track 174 is brought to the horizontal position and is held by the time delay relay (TDRb). When shifting assembly 14 reaches the position shown in dotted lines in FIG. 1 limit switch LS13 is opened and deenergizes relay (SB). With shifting assembly 14 at the position shown in dotted lines in FIG. 1 limit switch LS-24 is opened to deenergize the solenoid to extend core bar releasing pin 164 so as to hold core bar 2 thereon. At the same time limit switch LS-19 is closed. This energizes the relay SP for moving shifting assembly 14 forward and also time delay relay (TDR-b) times out. However, relay (SF-r) closes and starts the motor for drive means 54 of shifting assembly 14 in the proper rotation. When time delay (TDRh) times out shifting assembly 14 returns to the rest position.

Limit switch LS17 is a safety limit switch to limit the size of the roll of web material being wound on core bar 2. If the operator fails to push button (PB-2), safety limit switch LS17 will actuate the shifting assembly 14 so that it will return to its raised position so that the web material can be out. When shifting assembly 14 is at its raised position the following occurs: limit switch LS18 is opened thus stopping the movement of the shifting assembly by dllrgizing relay (SF)this releases clutch 64 and 8 applies brake 80. When limit switch LS-31 is opened the lowering core arm slowly lowers core bar 2 to release core bar release pin and the solenoid is energized to put the shifter door locking bar 174 in a vertical position. With limit switch LS7 closed and limit switch LS17 opened the apparatus is ready to repeat the sequence of cutting the web material.

It is apparent that many variations in design and changes may be made in the illustrated and described embodiments of my invention without departing from the spirit and scope thereof.
