Definitions

  • the invention relates to a device for the continuous winding of webs, preferably webs of thermoplastic material, on winding shafts or cores to winding rollers, with the preferably provided with a drive winding shaft arms, with an engageable with the winding shaft or winding roller pressure roller, with a the web at a roll change severing cutting knife and with a device for winding the formed by the separating cut new web start on the winding shaft or winding tube.
  • a particular problem with devices of this type is to wind the new web beginning formed during the roll change by the separating cut on a new winding shaft or winding tube. It is known to provide the Wickkelhülse or the winding core with a sticky order to Anwickeln the web start of supplied at a constant speed web, where the web start of the accelerated at web speed winding shaft or winding tube adheres.
  • the handling of tacky winding cores or winding shafts is complicated and difficult.
  • the object of the invention is to provide a device of the type described above, which allows independent of the respective diameter of the winding shaft or the winding tube a simple Anwickeln the web changes formed by separating cuts Bruanffite on the winding shafts or cores.
  • the means for Anwickeln from a web start providing the electrostatic charge charging electrode, which is arranged at a predetermined distance from the web and is coupled via transmission means with the movable pressure roller, that their distance from the web independently remains constant from the diameter of the winding shaft or winding tube.
  • the carriage is movable in or parallel to a plane which is spanned by the axes of the winding shaft and the pressure roller.
  • the carriage can be moved in the machine frame by a geared motor whose pinion meshes with a rack of the carriage.
  • the control of the geared motor can be done by a computer.
  • the separating knife is expediently held on the carrier carrying the charging electrode. According to a simple embodiment it is provided that the separating knife is movable transversely to the web by a rodless pneumatic cylinder.
  • a mirror image to the mirrored plane which is spanned by the axes of the winding shaft and the pressure roller, a second trackable charging electrode with separating knife.
  • a rear plate-shaped side part 1 can be seen, which is part of a machine frame.
  • the front side panel is removed to better visualize the devices located between the side panels.
  • a carriage is guided horizontally movable. Of the carriage also only the rear side wall 2 is shown, since the front side wall is again removed for better illustration.
  • the side walls 1 of the carriage are interconnected by crossbeams, not shown.
  • the side walls 2 are guided in dashed lines guides 3 of the side parts 1 slidably.
  • At its upper side edge at least the side wall 2 is provided with a rack 4 which meshes with the pinion 5 of a geared motor 6, which is controlled for moving the carriage with the side walls 2 of the electronic machine control.
  • two-armed levers 8 are pivotally mounted on both sides, their arms 10 pointing in the direction of the winding sleeve 9 carrying the charging electrode 12 extending over the width of the web 11.
  • the inner arms 13 of the two-armed lever 8 are provided with journals 14, on which rollers 15 are mounted, which are guided in existing from elongated guides 16 of the side parts 1 of the frame.
  • the guides 16 exist from an obliquely extending portion 17 and a subsequent thereto parallel to the guide 3 extending portion 18th
  • a separating knife 19 moves across the width of the web 11.
  • rockers 20 On both sides of the shaft 7 rockers 20 are pivotally mounted on the inner sides of the side walls 2 of the carriage, which are pivotable by pneumatic cylinders 23, the piston rods 21 are pivotally mounted on pins 22 of the rockers 20.
  • the cylinders 23 are pivotally mounted on pins 24 of the side walls 2 of the carriage.
  • the rockers 20 carry above the pneumatic cylinder 23 journals 30 on which coupling members 31 are mounted.
  • the coupling members 31 are hingedly connected at their rear ends in the hinge points 33 with arms 32, the upper ends of which are pivotally mounted on journals 34 of the side walls 2.
  • the coupling members 31 project beyond the rockers 20 in the direction of the winding tube 9. Between the free ends of the coupling rods 31, the pressure roller 38 is mounted.
  • the electrode 12 may consist of a series of needles and is laterally bordered by strips, which cover this protective.
  • the arrangement of the knife 19 with cylinder on the support of the electrodes 12 results in the activation of the cutting blade to severing just above the nip between the winding tube 9 and the pressure roller 38, so that a web start with a short flag is formed.
  • the web 11 runs in the direction of the arrow A and is supplied to the pressure roller 38 by a guide roller 39, which may for example be mounted between the side walls 2 of the carriage.
  • the two-armed lever 8 with electrodes 12 and Schneidmessem 19 and the guides 16 for the rollers 15 of the inner arms of the two-armed lever 8 are arranged in mirror image to a central plane 40 which extends through the axes of the winding tube 9 and the pressure roller 38. In this way, a simple conversion of the winding device to left-right winding is possible.
  • FIGS 4 to 7 show the extracted from the figure 1 items and assemblies.
  • winding cores or winding shafts 9, 9 ', 9 ", 9' '' of different diameters can be inserted into the winding device, by moving the carriage 2 and pressing the pressure roller 38 on each winding tube or winding shaft
  • the two-armed lever 8 is pivoted by corresponding movement of the rollers 15 in the inclined oblong holes 16 in such a way that the electrodes 12 are independent of the diameter the winding tubes 9, 9 ', 9 ", 9"' always have the same distance from the running of winding tubes 11 web.
  • the web 11 passes over a guide roller 41 to the winding roll 42, which is almost finished wound between the other arms of the turret winder.
  • Fig. 7 is a plan view of parts of the winding device, partially in section, can be seen.
  • the side wall 1 of the machine frame is provided with a slot forming a guide 16, in which the roller 15 is guided, which is mounted on the inwardly facing lever arm 13 of the two-armed lever 8.
  • the two-armed lever 8 is supported by the journal 7 on the side wall 2 of the carriage, which is guided over guide pieces 44 in the direction of the double arrow C on guides 3 of the frame.
  • the pointing in the direction of the winding tube 9 arm 10 of the two-armed lever 8 carries the electrode 12, which provides the role of the winding tube 9 running web 11 before performing the separation cut with an electrostatic charge during roll change. This charging takes place in a known manner, wherein the winding shaft may have the counter-potential to the charging electrode 12.
