Definitions

  • the invention relates to a device according to the preamble of Claim 1
  • a device is known from EP 462 157 B1.
  • This device there is a cutting knife on the Splicing device, which is designed as a slim hollow cylinder and a Has suction zone.
  • the cutting knife is arranged in a groove that in the splice element is formed.
  • the cutting knife has its own Actuator that is set in motion during the cutting process. It this naturally results in a relatively complicated structure of the Splice elements with a relatively strong weakening of the same in in terms of stress, because the groove the cylindrical shell interrupts.
  • DE 34 40 107 C2 describes a device for connecting the end of one running material web with the beginning of a second material web.
  • a knife arranged separately from the splice element is provided, which is moved against a stretched track section.
  • DE 39 01 854 A1 describes a similar device in which the web against the Cutting edge of a cutting device is moved; the cutting device and the splice element are arranged separately from one another.
  • EP-A-0 299 180 discloses an apparatus for connecting the web end an outgoing winding roll with the outer layer of a subsequent one Idle reel with a perforated splicer tube. According to this The splicer tube can be rotated around its own axis. Of however, there is no question of an independent drive. That splicer tube is thus not arbitrarily angularly positionable.
  • the invention has for its object a device according to the Preamble of claim 1 to be designed such that the web during the Splicing is held tight, so that the splicing to a successful result.
  • the drum is shown with two circles 1 and 1 'in dash-dot lines, whereby the drum 1 'has the largest possible extent.
  • the old one, now calm provided, web winding 9 expired web is denoted by T.
  • she will by the splice element 2 from the position shown in the extended position dash-dotted position when swiveling the same taken away.
  • This swiveling movement is carried out by swivel arms 3 allows, which are attached to the stand 12, which is also the first Deflection roller 5 carries for the web. Further deflecting rollers 21 and 22 guide the Train on.
  • the separating device is indicated by 10, with one cutting edge 11 and an actuator 15 e.g. in the form of a hydraulic Hoist is provided.
  • the separator is in the Working position drawn in which the cut of the web at stationary cutting edge or knife device through the tensioned web itself he follows.
  • This is also the one working position of the splice element 2, which as tubular cylinder is indicated and a suction zone 4 in the form of a perforated jacket.
  • the inside of the Pipe under negative pressure.
  • the associated vacuum connection is here not shown.
  • Another working position is given, in which the splice element - dotted - on the web wrap 1 smaller diameter is present.
  • the top position of the Splice elements is the waiting position in which this is in remains in its original position.
  • the splice element 2 When swiveling the splice element 2 into the other Working position in which the splicing process takes place, can preferably the splice element about its own axis be rotated by an appropriate drive so that the web remains taut during this process.
  • the splice element is pulled out into the upper one shown end or waiting position swung back, then the new drum through a familiar one, but not here shown transport device in the place of the old Web winding 9 placed in the usual holder and then the splicing process by applying the splice element 2 to the Scope of the new drum performed.
  • the last turn of the new drum an adhesive application to this splice, e.g. in form of double-sided adhesive tape.
  • the path T ' runs then essentially in the horizontal direction to the first Deflection roller 5 out.
  • the device is relatively simple and that also the maximum specified here Swivel range of the swivel arms 3 by a corresponding one Lifting device 14 - e.g. hydraulic type - without further ado is feasible.
  • a similar arrangement results from reverse course of the reel and the old reel in In the case of an opposite winding direction of the same.
  • the arrangement according to the invention shown in Figure 2 corresponds in principle to that of Figure 1. Im only the knife device has been significantly changed.
  • Stand 24 is provided next to the drum, which moves away from the unwind stand 41 with the bearing 36 of the respective Drums are located.
  • the knife device consists of the Knife 11, an elongated, rod or bar-shaped Beam 31 and side beams 25, which are elongated Hold carrier 31.
  • the carrier 31 extends along the Drums as well as the knife 11 '.
  • the side straps 25 are here in the guideways 27 by means of rollers 29 and 30 the stand 24 out.
  • the drive takes place via a chain 34 and one of the sprockets 32 and 33 via one here Drive motor, not shown, e.g. an electric motor.
  • Figure 3 is a similar drive device for the Knife device shown, here also a chain, a rope or a toothed belt 40 can be used.
  • the drive is via a hydraulic one or pneumatic actuating cylinder 39 and a lever 38, the each on the side supports 25 of the knife device is attached.
  • Figure 4 is a similar device with respect to Knife device shown as in Figure 2.
  • the guideway of the slide shoe 53 is indicated with 54.
  • the whole thing is from a console 56 worn with attachment 57. This rests on a stand 12 ', which is also the first pulley 5' for the web records.
  • Knife actuation device has the advantage that Obstacles can be avoided by the knife, being in In these cases the obstacle is practically the old web winding 9 is.
  • Through the guideways can be quite cheap Cutting position and in this way comes very close to the upper circumferential region of the web winding 9 when it is in has reached its cutting position.
