Description

  • The invention relates to a device for introducing a winding tube into a winding machine with at least one support roller and at least two winding brackets, with opposing mandrels receiving the winding tube and at least one winding tube gripper that can be pivoted transversely to the support roller axis between a winding tube receiving position and a winding tube delivery position.
  • Such a device is described in DE-A 32 43 994. In this known device, two oppositely movable ejection bars are arranged above a central support roller, on which slides with core tube insertion devices and clamping claws are arranged. Such core tube insertion devices move with the ejection bar and require additional, extendable guide rails for the core tube on holding devices in order to guide the core tube into the region of the clamping heads after the clamping claws have been released. However, there is no precise guidance and mounting of the core tube in front of the clamping heads, since the core tubes should roll freely into the area of the clamping heads. In addition, such devices are only suitable for winding machines with ejection bars. There is therefore no winding machine without such ejection bars Possibility to use such a device. Furthermore, with devices that require the additional extendable guide rails, it is not possible to use driven clamping heads. Such clamping heads are used in addition to the drive via the support rollers in order to achieve a greater winding hardness in the region of the winding tube when the weight of a roll is not yet sufficient. It is not possible to axially move driven clamping heads to insert a new sleeve into the winding blocks. The winding trestles must therefore be moved apart and brought together again. However, since the additionally extendable guide rails are now arranged on the winding trestles in the known device, they are moved with the winding trestles, so that functional insertion is not possible.
  • From GB-A-2 136 403 it is known to lift new winding tubes from below into vertically linearly movable tube holders into a delivery position which is essentially axially aligned with the holding mandrels. Due to the tube feed from below, it is not possible to feed the new winding tubes centrally for both sides of the backup roller. A separate device for feeding new winding cores is required for each side of the support roller, the winding cores having to be individually positioned in a costly manner in the direction parallel to the axis of the support roller.
  • The invention has for its object to enable a precise, independent of the other movements and functions of the winding machine positioning the empty winding tubes, so that the insertion is simplified and accelerated and can run largely automatically.
  • Based on this task, it is proposed in a device of the type mentioned at the outset to mount the bobbin gripper telescopically according to the invention on a slide which can be moved in guides of a guide cross-member arranged above the support roller and to make it movable in a bobbin tube dispensing position which is essentially axially aligned with the spikes. In this way, the movement of the winding tube gripper from the Decoupled movement of the jacks. A fully wound roll is also ejected completely independently of the movement of the winding tube grippers. Since the winding tube receiving position is outside the backup roller, the winding tubes can either be inserted into the winding tube gripper safely by hand or automatically picked up by the winding tube gripper.
  • Since the winding sleeve gripper is mounted on a slide that can be displaced in guides on the guide crossmember, adaptation to different web formats and additionally moving out of the winding sleeve gripper in the direction of the axis of the support roller is possible. During operation, the carriage can then be locked in place by means of a locking mechanism acting between the carriage and the guide crossmember.
  • If the pivot axis for the winding tube gripper is arranged in the area below the guide crossmember, a sleeve pliers can be arranged below this pivot axis in the vicinity of the support roller, so that the winding tube receiving position above the backup roller results approximately in the longitudinal center plane and the winding tube dispensing position is pivoted sideways out of the longitudinal center plane.
  • In view of the fact that the winding rollers are arranged on a gap on both sides of the central longitudinal plane of the support roller, with end faces aligned in pairs in each case, two winding tube grippers which can be pivoted in opposite directions can be arranged on each slide.
  • In order to be able to insert the winding tubes into the winding tube grippers during winding, the guides for the slides are extended beyond the length of the support roller. The slides with the winding tube grippers can thus be pulled out of the winding machine, equipped with winding tubes and pushed back into the winding machine. The winding sleeves butt with their end faces and the first into the Winding machine pushed-in winding sleeve hits a stop, which determines the position of all winding sleeves with respect to the winding stations.
  • If the length tolerance of the winding cores is not precisely matched to the distance between the winding stations and there is enough space in the axial extension of the back-up roller, the slides can be coupled with each other by means of a spacer corresponding to the length of the winding cores to be inserted, so that the carriages with the winding core grippers as a whole Let it slide out of the winding machine in the axial direction. The prerequisite is that the guides for the slides are extended over the length of the back-up roller approximately in accordance with the total length of the winding tubes to be inserted.
  • In its simplest form, the winding tube gripper consists of a carrier, a slide which is displaceably mounted on the carrier and a sleeve clamp holder which is pivotably mounted on the slide. The sliding of the slide relative to the carrier and the pivoting of the sleeve clamp holder relative to the slide are preferably carried out with the help of a hydraulic or pneumatic piston-cylinder unit or by an electric motor drive. In this version, the pivot axis for the sleeve pliers holder is located approximately in the middle between the sleeve pliers and the attachment to the guide crossmember.
  • The winding tube gripper can also consist of a carrier, a slide guide pivotally mounted on the carrier and a sleeve pliers holder designed as a slide. In this case, the swivel axis is located near the attachment to the guide crossmember. In this case, too, the slide can be moved and the winding sleeve gripper swiveled by a hydraulic or pneumatic piston-cylinder unit or by an electric motor drive.
  • The telescoping and pivoting of the winding tube gripper can advantageously be carried out by means of a single one Carry out the actuating device when the slide guide for the sleeve pliers holder designed as a slide is part of another slide guided in the pivotably mounted slide guide and coupled to the carrier via a link. In this case, however, it is necessary to control the swiveling out and the telescoping in such a way that no incorrect movements occur.
  • It is particularly advantageous for the control of the movement sequence if the slide is formed in two parts and an upper slide part is coupled to a handlebar, while a lower slide part carries the slide guide for the sleeve tongs holder. In this case, a hydraulic or pneumatic piston-cylinder unit is arranged between the pivotable slide guide and the lower slide part and a further hydraulic or pneumatic piston-cylinder unit between the lower slide part and the sleeve clamp holder. In addition, the path of the upper slide part is limited by two stops arranged on the pivotable slide guide, the path of the lower slide part by a stop arranged on the upper slide part and a stop arranged on the slide guide, and the path of the sleeve pliers holder by a stop cooperating with the lower slide part.
  • Springs arranged between the two slide parts and between the lower slide part and the sleeve tongs holder, one of which is designed as a tension spring and one as a compression spring, ensure that the winding tube gripper is pivoted out before telescoping and the tube tongs are closed before the tube tongs holder is retracted.
  • For this purpose, the piston-cylinder unit coupled to the lower slide part and the sleeve tong holder does not act directly on the sleeve tong holder, but indirectly via a locking lever connected to the sleeve tong.
  • In order to achieve a synchronism of the two jaws of the sleeve pliers, these can be coupled to one another via a toothing.
  • Another means of controlling the winding tube receptacle and the winding tube output in accordance with the position of the winding tube gripper consists of a bolt which interacts with the tube tongs holder and the carrier and is movably mounted on the pivotable slide guide against spring force. In the swiveled-in position of the winding tube gripper, this bolt is unlocked, while in the swung-out position it holds the tube tongs holder in the retracted position, so that opening the tube tongs in the winding tube dispensing position is possible without moving the tube tongs holder.
  • If the winding tube grippers cannot be moved axially, the winding tubes must be picked up by the winding tube grippers in the area of the winding stations, so that the winding tubes must be brought into the winding tube receiving position from the outside.
  • This can be achieved by means of a sleeve trough arranged above the support roller in the region of the winding tube receiving position of the winding tube gripper and preferably extending over the length of the support roller.
  • The winding tubes can be pushed onto this tube trough from one end of the support roller, with their end faces abutting, until there is a winding tube in the area of each winding station. However, the tube trough can also be slidably supported by means of guide rails on supports arranged on the winding frames, so that it can be pulled out of the winding machine in the axial direction of the support roller and can be covered with winding tubes. The carriers are preferably provided with rollers. In order to avoid displacement of the sleeve pliers holder, the sleeve channel can also be designed to be height-adjustable.
  • The invention is explained in more detail below with reference to several exemplary embodiments shown in the drawing. The drawing shows:
    • 1 is a schematic side view of a winding machine with a winding tube gripper,
    • 2 is an enlarged view of the winding tube gripper from FIG. 1 in side view,
    • 3 shows a schematic top view of a winding machine,
    • 4 is a partial enlargement of a winding machine in plan view,
    • Fig. 5 is a partial view of a winding machine with a winding tube gripper and a tube trough.
  • Only the parts of the winding machine with the different designs of the winding tube gripper are shown that are important for understanding the invention. A material web 1, for example a paper web, is fed via a guide roller 2 and a deflection roller 3 to several longitudinal cutters, each consisting of an upper knife 4 and a lower knife 5, and divided into a number of narrower paper webs which are wound into rolls in the winding machine. Via a guide roller 13, the paper webs arrive at a support roller 6 which is designed as a suction roller and which supports the winding rollers and sets them in rotation when they are rolled up.
  • In the example shown (FIG. 3), five winding stations 7 to 11 are arranged above the support roller 6, but laterally from the vertical longitudinal center plane of the support roller 6. The winding core of the rolls consists of winding sleeves 12. The winding sleeves 12 are guided by means of mandrels 17 in pairs alternately on one and on the other side of the longitudinal center plane of the support roller 6 arranged winding stands 14.
  • In order to be able to adapt to the increasing diameter of the winding rollers 7 to 11, winding carriages 15 are arranged on the winding stands 14, which are operated by means of hydraulic or pneumatic piston-cylinder units 18 can be moved along a guide on the winding frames 14. The mandrels 17 can be axially displaced by means of a traversing motor 16 arranged on each roll-up carriage 15 in order to release or take up the winding tubes 12.
  • The winding brackets 14 are slidably mounted in guides 19 on a guide cross-piece 21 running in the axial direction of the support roller 6 and can be adjusted to the required winding width by means of a traversing motor 20. The guide cross member 21 is fastened to cross members 22 carried by stands 23.
  • In the winding machine shown, an additional pressure is exerted on the initially flexible winding sleeve 12 during the first windings. This is achieved by means of pressure roller rockers 27 with pressure rollers 30 arranged on a pressure roller crossmember 24 which can be moved vertically by means of a lifting drive 25. The pressure roller rockers 27 are pivoted by means of a piston-cylinder unit 28 and are mounted on a slide 26 which can be moved in guides 29 on the pressure roller crossbar 24.
  • A winding tube gripper 33 is arranged above the support roller 6 in the free space between the winding stations 7 to 11. For this purpose, a guide carrier 32 (FIG. 2) runs below the guide cross member 21, which extends over the length of the support roller 6 and beyond by such a part that the winding tubes 12 can be inserted into the winding tube gripper 33 outside the winding machine. The winding tube gripper 33 therefore consists of a carrier 31 which can be moved on the guide carrier 32, on which a carriage 34 which can be displaced in the vertical direction is guided. A sleeve clamp holder 35 is articulated on the slide 34 in a pivot axis 36. The carriage 34 is displaced by means of a first piston-cylinder unit 37, while the sleeve pliers holder 35 is pivoted by means of a second piston-cylinder unit 38. Outdoors, the support roller 6 facing end of the sleeve tong holder 35 is a two-jaw sleeve 39 is arranged. The winding tube 12 is held in the tube pliers 39 by means of pincer rollers 40.
  • During winding, the winding tube grippers 33 are moved on the guide carrier 32 until they lie outside the region of the support roller 6. Then a winding tube 12 is inserted by hand into two adjacent winding tube grippers 33 and pushed along the guide carrier 32 over the support roller 6. Although the winding rolls lie on a gap, but with the end faces aligned in pairs, the winding sleeves 12 with the abutting end faces can be pushed into the winding machine until the first winding sleeve 12 abuts a stop on the last winding bracket 14 corresponding to the winding station 8 (FIG. 3). With sufficient length accuracy, the other winding tubes 12 are located exactly in the area of the winding stations 7, 9, 10, 11.
  • After the rolls have been completely wound, they are removed from the winding machine and empty winding tubes 12 have to be inserted into the winding stations 7 to 11.
  • For this purpose, the piston-cylinder units 38 are first actuated to pivot the sleeve tong holder 35, and then the slide 34 is lowered using the piston-cylinder unit 37. As a result, the winding cores 12 reach the area of the mandrels 17 on the roll-up slide 15. The mandrels 17 are moved into the winding cores 12 by means of the traversing motors 16 and the winding core grippers 33 are returned to their original position, the winding cores 12 being released by the sleeve pliers 39 will. Now the sleeves 12 held by the mandrels 17 on the roll-up carriage 15 are moved against the support roller 6, the pressure roller rockers 27 with the pressure rollers 30 are lowered onto the winding sleeves 12, and the winding can begin.
  • While the guide carrier 32 is designed as a T-carrier in FIG. 2, parallel guide rods 41 are shown in FIGS. 3, 4 and 5, on which carriages 42 are arranged displaceably. These carriages 42 can each be locked on the guide cross member 21 when they have assumed the correct position in relation to the winding stations 7 to 11.
  • On each carriage 42 (FIGS. 3 and 4), two winding tube grippers 33 which are pivotable in the opposite direction are articulated, and spacers 44 are fastened between the individual carriages 42, so that length tolerances in the winding tubes 12 have no influence on their position with respect to the winding stations 7 have to 11. In this case, the carriages 42 connected by means of the spacers 44 must be pushed out as a whole on the guides 41 from the region of the support roller 6 when the winding tubes 12 are inserted into the winding tube grippers 33 by hand, as described above.
  • Axial displacement of the winding tube gripper 33 is not necessary if, as shown in FIG. 5, a tube trough 62 is arranged in the longitudinal median plane above the support roller 6. This sleeve channel 62 can rest with guide rails 63 stationary on rollers 64 of the winding blocks 14, so that the winding blocks 14 remain movable to change the format without the sleeve channel 62 moving.
  • The winding tubes 12 are pushed into the winding machine on the tube channel 62 and, after the foremost one has hit a stop, are in the winding tube receiving position in the region of the individual winding stations 7 to 11.
  • Furthermore, it is also possible to arrange the sleeve channel 62 on the rollers 64 so that they can move out of the area above the support roller 6 and can be covered with winding tubes 12 outside the support roller 6. Then the sleeve trough 62 is pushed back into the winding machine until the winding sleeves 12 have reached their receiving positions.
  • If the winding tubes 12 are brought into the winding tube receiving position by means of the tube channel 62, it is not necessary to move the winding tube grippers 33 independently of the winding blocks 14, so that these winding blocks 14 can be used as carriers for the winding tube grippers 33. Such a winding tube gripper 33 is shown in FIG. 5. It consists of a carriage 42, which is displaceable parallel to the support roller axis on the guide 41 mounted on the guide cross member 21. The longitudinal displacement of the winding tube gripper 33 with respect to the winding frame 14 is controlled by a piston-cylinder unit 83 which connects the winding frame 14 and the carriage 42 to one another.
  • In a pivot axis 136 on the carriage 42, a pivot holder 145 is arranged with a carriage guide 45, on which a two-part carriage consisting of an upper carriage part 50 and a lower carriage part 51 is guided. A link 49 is arranged between the upper slide part 50 and a lateral extension 85 of the slide 42, while a further slide guide 52 for a sleeve pliers holder 46 designed as a slide is arranged on an extension 86 on the lower slide part 51. A piston-cylinder unit 47 is articulated on the swivel holder 145 and on the lower slide part 51 and a further piston-cylinder unit 48 on the lower slide part 51 and a locking lever 80 for the sleeve pliers 39. A tension spring 58 is arranged between the upper slide part 50 and the lower slide part 51 and a compression spring 59 is arranged between the extension 86 on the lower slide part 51 and the sleeve clamp holder 46.
  • The free path of the upper slide part 50 is limited by adjustable stops 53, 54 attached to the swivel holder 145, the free path of the second slide part 51 by an adjustable stop 55 arranged on the upper slide part 50 and an adjustable further stop 56 arranged on the slide guide 45. The path of the sleeve pliers holder 46, on the other hand, is determined by an adjustable stop 57 which interacts with the further slide guide 52.
  • A bolt 61 is articulated on the further slide guide 52 and has at its one free end a locking lug 66 which cooperates with a projection 67 on the sleeve pliers holder 46. The other free end of the bolt 61 interacts with a plunger 84 arranged on the lateral extension 85 of the carriage 42 against the action of a spring 65 in such a way that unlocking takes place in the illustrated vertical position of the swivel holder 145.
  • In the position shown in FIG. 5, the winding tube gripper 33 is in the winding tube receiving position. The piston-cylinder unit 47 is fully retracted so that the upper slide part 50 bears against the stop 53 and the lower slide part 51 bears against the stop 55. The handlebar 49 thereby holds the slide guide 45 in the vertical position shown. The piston-cylinder unit 48 has already moved back a certain distance from its fully extended position, so that the sleeve pliers 39 are closed over the winding sleeve 12.
  • In order to achieve a uniform movement of the two legs of the sleeve pliers 39, these are coupled to one another via a toothing 60. The piston rod of the piston-cylinder unit 48 engages the sleeve pliers 39 via the locking lever 80. By means of the compression spring 59, the sleeve tong holder 46 is pushed into the end position shown, since the bolt 61 is in the open position. Now retracts the piston-cylinder unit 48, the sleeve tongs holder 46 is raised with the sleeve tongs 39 and the winding tube 12, so that the winding tube gripper 33 can be pivoted from the winding tube receiving position into the winding tube dispensing position. This is done by extending the piston-cylinder unit 47. The lower slide part 51 moves downward and takes the upper slide part 50 with it via the tension spring 58, as a result of which the link 49 presses the swivel holder 145 with the slide guide 45 into the deflected position (shown in broken lines). The locking lug 66 lies behind the projection 67. As soon as the upper slide part 50 hits the stop 54, it stops and only the lower one Carriage part 51 continues to move, so that the winding tube gripper 33 extends into its winding tube delivery position.
  • In order to open the sleeve pliers 39, the piston-cylinder unit 48 is extended again. Since the latch 61 with its locking lug 66 is now behind the projection 67, the sleeve pliers holder 46 does not move, but the sleeve pliers 39 open immediately. After the winding tube 12 has been taken over by the mandrels 17 on two adjacent winding frames 14, the piston-cylinder units 47, 48 are actuated again in such a way that the winding tube gripper 33 returns to the winding receiving position.
