Definitions

  • the invention relates to a device for reel changing and cross cutting for multiple winding machines of webs, with at least two winding stations, the center of which is arranged on a common swivel circle around the center of the winding station holder, and also with a holder having at least one deflecting roller, which is used for deflecting the incoming web the empty winding tube is formed, further with a cross cutter for severing the web at an interface behind the winding tube and in front of the deflection roller, and with a pressure roller for pressing the incoming web against the winding tube.
  • the changeover process should be possible without interrupting production. It has so far been necessary to wind up the web depending on its properties on a particular winding tube diameter and to match all parts of the changing device and cross-cutting device to the corresponding, constant winding tube diameter.
  • the known devices therefore allow a quick reel change only as long as material with the same properties is wound on winding cores of the same diameter.
  • the invention is based on the object of designing a device of the type presumed to be known in such a way that it enables a change of winding cores of different diameters without changeover work and without interrupting the web feed.
  • the center of the sleeves - regardless of the type of receptacle - always remains on the swivel circle, even with different diameters. Depending on the diameter, the center point is only shifted by half the difference in diameter between the smallest sleeve and the sleeve deviating therefrom.
  • the line of intersection between the swivel circle and the peripheral surfaces of the empty cores is always the same.
  • the interface lies directly in the area of the swivel circle in the immediate vicinity of the intersection line between the swivel circle and the peripheral surface of the empty sleeves.
  • the multiple winding device is generally designated 1. It has two winding stations 2 and 3 arranged pivotably on a winding station holder, not shown. The centers of the winding stations 2 and 3 lie on a common swiveling circle 4, the center 1a of which represents the pivot point of the winding station holder.
  • a changing device is denoted by 5 and has two deflecting rollers 6 and 7 as well as a cross cutting knife 8 pivotably arranged about the pivot point of the deflecting roller 7 with a counter-holder 9 assigned to it.
  • the winding stations 2 and 3 are suitable for accommodating winding sleeves 11, 12, 13 and 14 of different diameters, either without an axle or with winding shafts.
  • the web 15 coming from a production machine is first fed to the multiple winding device 1 via the pressure roller 10 and wound up at a winding point 2 or 3.
  • the empty winding tube 11, 12, 13 or 14 pivots to a stop point common to all winding tubes, namely to the straight line 16 between the swivel circle 4 and the outer diameter.
  • the center points 12a, 13a and 14a of the larger winding tubes 12, 13 and 14 are each offset by half the diameter difference with respect to the diameter of the winding tube 11.
  • the locking of the winding point holder in the position corresponding to the respective diameter can be controlled in different ways, for example by means of a limit switch (not shown), a photo cell or a process computer.
  • the counterholder 9 is fed between the pressure roller 10 and the running web 15 to the deflection roller 7.
  • the cross cutting knife 8 strikes the running web 15 at an interface between the empty winding tube 11, 12 13 or 14 and the counter-holder 9 up to the pressure roller 10.
  • the rest of the web continues to be fed to the winding station 3 during the new start of the web as a tip 17 between the pressure roller 10 and the winding tube 11, 12, 13 or 14 is guided and wound up.
  • the cross cutting knife 8 is placed on the web at one Place approximately on the swivel circle 4 or within the swivel circle 4.
  • the web 15 is separated by the cross cutting knife 8 and the beginning of the subsequent web is placed as a tip 17 on the winding tube.
  • a brush or an air jet can serve the web 15 as an investment aid 18.
  • the cutting line of all different sleeves 11, 12, 13 and 14 is selected so that the cross cutting knife is placed on the web 15 with the smallest winding sleeve 11 almost on the swivel circle 4 and with the winding sleeves 11, 12, 13 and 14 within the swivel circle 4 he follows.
  • the outgoing web 15 from all the winding tubes 11, 12, 13 and 14 to the deflection roller 7 forms, with unchanged position and movement of the cross-cutting knife up to their separation point, short lobes 17 which are guided wrinkle-free and without a change between the pressure roller 10.
  • the pivoting direction of the cross cutting knife 8 ' is changed because of another pivot point.
  • the cross cutting knife is placed on the outgoing web in the same way as in the first embodiment either on the swivel circle or within the swivel circle.
  • the transverse separating knife 8 is designed as a sickle or hook knife and is guided on a guide carriage 19 across the winding sleeves 11, 12, 13 and 14.
  • the interface lies on the swivel circle or within the swivel circle 4.
