Definitions

  • the invention relates to a device for automatic cross cutting and winding of webs.
  • a frame which extends over a pair of trestles, each of which carries a core on which the fabric is to be wound.
  • the frame is provided with an arm which is optionally movable on the frame so as to be alternately positioned over one or the other trestle, and the arm can also optionally rotate on the frame about a horizontal axis, so that the the protruding end of the arm can be brought into surface contact with the core of one or the other trestle and can gradually pivot upwards, as the material is wound onto the core and its diameter increases.
  • the frame and arm are equipped with a roller system through which the fabric is guided and transported to the core.
  • the fabric is wound on one of the cores; until this carries a predetermined length of fabric, after which the device is automatically stopped by an appropriate switch.
  • An operator then has to perform a number of manual actions to set up the fabric winding device on the other, empty core.
  • the operator must first cut the now stopped fabric with a hand-operated shear and then swing the arm up to fully expose the core, move the arm along the frame until it is positioned over the empty core, and then the arm down pivot until the feed roller at its projecting end is in surface contact with the empty core.
  • the operator must next grasp the cut edge of the fabric and manually wind several turns of the fabric around the empty core, after which the device is restarted.
  • a device for winding and cross cutting of webs is already known, in which a first and a second driven roller is provided.
  • the first driven roller is assigned an engagement device which can be moved into an operating position in order to forcibly engage the running material web.
  • Cutting elements are also arranged between the first and the second driven roller.
  • DE-A-3 318 803 discloses a device for continuously winding a material web onto roll cores, the material web also being fed continuously and cut off in connection with a change in position of the roll cores.
  • the material web is guided in this device during the winding process over several deflecting rollers, which are mounted between a pair of first levers pivotable about a pivot point and from there in the web transport direction via a combined pressure, deflection and connecting roller, which can be pivoted in one to the first lever attached bracket is provided.
  • the roller the diameter of which increases continuously, pivots the first levers by rotating about the pivot point, while the first roller core is in a first position in a roller holder which can be rotated about a pivot point.
  • the first levers must be pivoted out of contact with the roller.
  • the roll holder is then pivoted about its pivot point, so that a second empty roll core, which must have an adhesive coating, takes the position of the first roll core in the first position. Meanwhile, winding onto the first roll continues in a second position, during which phase the web of material is guided on the holder by contact with the deflection rolls located between the first levers and with the combined first roll.
  • the second roll core must then be accelerated to a circumferential speed corresponding to the web speed before the first levers are pivoted in the direction of the second roll and the holder is pivoted such that a knife mounted in it cuts off the material web at substantially the same time that the Combined roller and a brush or a similar elastic element which is provided in the holder in the space between the combined roller and the knife, press the cut material web against the second roller core, which carries the adhesive coating.
  • the front end of the material web is to be immediately wound up into a new roll on the second roll core, while the cut-off rear end of the web is wound onto the first roll.
  • the invention has for its object not only to simplify such a device significantly in terms of its structure, but also to ensure with the device that the new web start arising from the cross cutting of the web is simply forced to the scope of the following take-up roller.
  • the running material web can be arranged on both sides of the between the first and the second driven roller Hold the cutting member inevitably during cutting and guide the web after cutting along the predetermined path of movement so that the cutting edge of the web is securely guided onto the surface of the take-up roller.
  • selectable engagement means include first and second transport means, one of which is engaged with the first drive means to hold the moving material therebetween as it is steered along the predetermined path of travel described above, and the other optionally to one Position movable, which extends along this predetermined movement path and in the direction of the second drive device to guide the material after the cut along the movement path and to guide it in a direction of rotation of the pick-up roller.
  • the transport device which is engaged with the second drive device is selectively movable to a position which is adjacent to a surface region of the second drive device in order to guide the running material onto the take-up roll in the opposite direction of rotation of the roll.
  • the web of material is normally passed over an idler roller held on the movable arms and a driven feed roller is supported on the movable arm at a distance from the idler roller, with the automatic cutter between the idler roller and the driven feed roller and the driven one Feed roller is arranged on the arms to form a nip in engagement with the pickup roller when the arm is moved toward the pickup roller.
  • a driven engagement roller is located near and normally spaced from the idler roller and the idler roller is placed on the arm for optional movement in an operating position where the running material is inevitable between the idle roller and the driven engagement roller just before the running material is cut by the automatic cutter.
  • the predetermined path of movement of the material is oriented substantially vertically to the pick-up roller.
  • the first embodiment of the present invention is shown in FIG. 1. It comprises a frame 10 with a plurality of supports 12 which support horizontal slideways 14, along which a conventional carriage 16 can be moved, which is movable by a chain 18 guided around disks 20, the chain being optionally driven by a motor 22, to move the carriage 16 backwards and forwards between its positions shown in solid and dashed lines.
  • a pair of parallel, movable arms 24, one of which is visible in Fig. 1, are mounted on the carriage 16 by an articulated shaft 26, and a chain 28 is connected at one end to an arm 24 while the other end of the chain 28 is connected to a sprocket 30 which sits on the piston rod 32 of a pneumatic or hydraulic cylinder 34, the sprocket 30 holding the arm 24.
  • the movement of the arms 24 in the horizontal direction is controlled by the movement of the carriage 16 along the slideway 14 and the vertical movement of the arms 24 by the cylinder 34.
  • a wide web of fabric is fed to the frame from a tenter frame or other known source (not shown) and passes over an idle roller 38 to be fed to a conventional compensator 42 which controls the speed of the fabric, such as it is wound on the rotating take-up roll or core 40 to compensate for changes in the peripheral speed of the take-up roll 40 during winding.
  • This compensator 42 is well known in the art and, briefly described, includes a freely movable feeler roller 44 which is arranged for vertical movement in a trough 46, the feeler roller 44 being guided on a chain 48 which extends around a sprocket 50.
  • the position of the feeler roller 44 is controlled to move the chain 48 and one of the sprockets 50 actuates a speed control potentiometer (not shown) to drive the rotational speed of the driven stock rollers on the arms 24 controls; which is described below.
  • the fabric 36 After the fabric 36 has left the feeler roller 44, it is passed around an idle roller 52 on the frame 10 and guided in the direction of the arms 24.
  • the arms 24 have an idle roller 54 disposed between them and a first driven roller 56 and a second driven roller or charging roller 58 disposed between the projecting ends of the arms 24.
  • the fabric 36 therefore runs in a predetermined trajectory from the surface of the second driven roller 58 and around the second driven roller 58 toward the surface of a driven take-up roller 40.
  • An automatic cutter is on the arms 24 in a position between the driven rollers 56 , 58, the cutting device comprising a cutting plate 60 and a rotatable cutting element 62, which is driven by a drive motor (not shown) with clutch and brake, in order to make one revolution during the cutting cycle and thus to cut off the running material 36 along a line, which is transverse to the direction of travel of the fabric between the driven rollers 56, 58.
  • This cutter is described in more detail in US-A-3,721,396.
  • the cutting member 62 rotates during the cutting cycle at a peripheral speed that corresponds to the speed of the running fabric 36 to perform a clean cut without interfering with the normal movement of the fabric 36.
  • a short conveyor belt 64 is on the arms 24 for optional movement under the control of a solenoid 66 between a first position shown in phantom in FIG. 1, at a distance from the surface of the first driven roller 56, and a second position, in which a stretch of the conveyor belt 64 inevitably holds the fabric 36 engaged between itself and the surface of the first driven roller 56.
  • the position and extent of the conveyor belt 64 are such that, in its second position or operating position, the material 36 leaving the conveyor belt 64 is guided along the predetermined path of movement of the material 36.
  • a second conveyor belt 68 is actuated by a solenoid 70 and moves between a first position (shown in dashed lines in FIG.
  • the main purpose of the device described above is to first build a complete bobbin on one of the take-up rolls 40, then move the arm 24 to a position near an empty take-up roll 40, cut the fabric and wind the fabric onto the empty take-up roll 40 begin, all automatically and without interrupting the runway during these operations.
  • the arms 24 are shown in dashed lines in the position that they would take just before a complete bobbin is wound on the right take-up roller 40.
  • the cylinder 34 is actuated, which swivels the arms 24 high enough for the full body to be removed, and the motor 22 actuates, which moves the carriage 16 and the arms 24 to the left, after which the cylinder 34 is actuated again to lower the arms 24 into the position shown in solid lines in FIG. 1, the second driven roller 58 coming into contact with the empty pick-up roller 40.
  • the fabric continues to be wound onto the right take-up roller 40, as shown in part by the partially dotted line 76.
  • control panel 74 actuates solenoids 66, 70 which actuate the first and second transport devices 64, 68 - as shown in solid lines in FIG. 1 - bring into contact with the first and second driven rollers 56, 58 so that the running material inevitably comes into engagement between the driven rollers 56, 58 and the transport devices 64, 68.
  • the control panel 74 then actuates the cutting element 62, which cleanly cuts the running fabric as described above, and the portion of the fabric below the cut is drawn through the right take-up roller 40 to complete this winding body.
  • the cutting edge of the moving fabric continues to be fed through the first driven roller 56 and the first conveyor 64 along the predetermined predetermined path of travel of the fabric until the fabric reaches the nip formed between the second driven roller 58 and the second conveyor 68 where it engages therethrough, wrapped around the surface of the driven roller 58 and guided toward the nip formed between the second driven roller 58 and the empty take-up roller 40 which is driven in a counterclockwise direction of rotation.
  • the pickup roller 40 may have a roughened surface or an adhesive material may be applied thereon to aid in winding the fabric thereon.
  • guide rails 78 can be attached to the arms 24 on either side of the insert 60 to aid in guiding the fabric along its predetermined path of travel after the cut.
  • the transport devices 64, 68 are returned to their original positions shown in dashed lines by the control panel 74, and the fabric continues to be wound onto the take-up roller 40 with the arms 24 upward about their pivot axis 26 pivot until the left bobbin is substantially complete, after which the above procedure is repeated to move the arms 24 and carriage 16 to the right and actuate the right take-up roller, which is empty and ready to take-up.
  • the apparatus of the present invention provides for automatic transfer of speed from a full take-up roller to an empty take-up roller without stopping the stock run and without manual operation of the fabric or device.
  • FIG. 2 shows a modified arm 124 that would replace the arm in the device of FIG. 1.
