Definitions

  • the invention relates to a device for winding in particular of adhesive-coated webs on a winding core, with a fixed first roller, over which the web runs and on the circumference of which the roll is supported along a first line of contact, further with a second roller, on the The winding is supported circumferentially along a second line of contact and with a third roller resting on the winding along a third line of contact, the position of the second and third rollers being adjustable depending on the winding diameter.
  • a fourth roller is arranged below the first and second roller. As the winding diameter increases, the second roller moves away from the first roller and a continuously increasing passage gap is created between these two rollers. The larger roll is pressed down with the help of the third roller and moves through the passage space until its underside is on the fourth roller arranged pivotably.
  • the movement sequence described for the various rollers is controlled via cam disks.
  • the known device is not suitable for winding problematic webs, in particular for winding webs coated with adhesive.
  • the aim must be that the contact lines of the roll with the three rolls mentioned do not shift as far as possible over the entire roll diameter.
  • the best winding results are achieved if the planes defined by the winding axis and the lines of contact of the winding core with the three rollers enclose constant angles during the entire winding process. In practice, this desired condition can only be met inadequately because the distance between the three different rollers would have to change to the same extent during the entire winding process in order to meet this requirement.
  • Such a theoretically favorable construction requires a very high level of design effort.
  • Winding devices are also known, in which a rotating belt is provided instead of the second roller. With this construction, too, an undesirable migration of the contact lines occurs in the course of the winding process.
  • this known construction it is also disadvantageous that, as the winding diameter increases, the line of contact between the winding and the winding tape constantly moves further into the free area of the winding blanket which is not supported by the deflection roller. This creates winding conditions that are not precisely defined.
  • the invention has for its object to provide a device of the type mentioned in such a way that it allows the greatest possible compliance with the requirement that the lines of contact between the winding and rollers shift with an increasing winding diameter to an innocuous extent with reduced effort.
  • the pressure force transmitted at the contact lines of the first and second rollers should remain approximately the same as far as possible during the entire winding process.
  • This object is achieved according to the invention in that the pressing force of the third roller is reduced in accordance with the increasing winding diameter and the second roller moves along a straight guide path, the planes running through the winding axis and the lines of contact over the entire winding diameter at least approximately equal angles to one another form and the storage of the second roller is arranged on a swivel arm on which it is displaceable by means of a servomotor.
  • a material web 1 runs over a suction belt 4 and over a first roller 3 onto a winding core 2.
  • a cross cutter 5 is arranged, which is switched by a length counter, not shown, and separates the material web after reaching the predetermined winding diameter.
  • the length counter not shown, simultaneously gives a signal to stop the suction belt 4.
  • the suction belt 4 that arises when the suction belt 4 stops Loop of the web 1 is stored, for example, via a pendulum roller, not shown.
  • the rotation of the first roller 3 is not influenced by the A b cutting process.
  • the winding core 2 is supported along three lines of contact on the first roller 3, the second roller 6 and the third roller 7.
  • the third roller 7 is designed as a pressure roller, the position of which can be adjusted via lever 8 by means of a servomotor 9.
  • the servomotor is mostly a pneumatic piston-cylinder unit.
  • the second roller 6 is supported on both sides in a bearing plate 10 which is inclined at an acute angle.
  • the guidance of the bearing plate 10 and thus the path of movement of the bearing plate 10 runs approximately below 30 ° to the horizontal.
  • the bearing plate 10 is adjusted by means of a servomotor 11.
  • the second roller 6 is guided in parallel via toothed racks provided on both sides, which are provided on swivel arms 13 likewise arranged on both sides.
  • the bearing plates 10 on both sides carry gears 12 a which are coupled to one another and run on the associated racks 12.
  • the end shields 10 are additionally guided in ball bushings, not shown.
  • the pivot arms 13 are pivotally mounted about the axis 13a and can be pivoted with the aid of the servomotor 14, which engages on the lever 13a fixedly connected to the pivot arm 13.
  • the position of the end shields 10 and thus the position of the second roller 6 is in the direction of the first roller 3 limited by stop pins 15 of different lengths, which sit on a rotatable stop disk.
  • the differently long tapping bolts 15 are provided for different sleeve diameters.
  • a photocell 17 is guided in a straight guide 22, which is only indicated schematically and is fixed on the swivel arm 13.
  • the photocell 17 is carried by a fork 21 which is pivoted about the bearing 25 on the swivel arm 13.
  • the fork is carried by a shoulder or a guide groove on the axis of the second roller 6.
  • the photocell 17 scans the winding diameter and sends an actuating signal to the servomotor 11 via an amplifier (not shown), which corresponds to the end shield 10 and thus the second roller 6 adjusted the diameter increase of the winding 20.
  • a sleeve magazine 18 with the winding cores 2a ready for a roll change.
  • a storage plate 19 which receives the finished rolls 20.
  • FIG. 2 shows a winding 20, which is completely wound except for the remaining area 19, which was separated from the web 1 by the cross cutter 5. From Figure 2 it can also be seen that the photocell 17 has moved with the pivotable fork 21 in a position corresponding to the winding diameter.
  • a pneumatic, curve-controlled fine pressure regulator 23 is provided, which influences the pressure of the servomotor 9.
  • FIG. 3 shows the released reel in the case of the storage tray, furthermore the swiveled-back swivel arm 13, the swiveled-up third roller 7 and the start of the new start of the web 1.
  • a new reel core 2a is in the ready position. After the winding 20 has been deposited, the new winding core 2a is released from the sleeve magazine 18 and the swivel arm 13 with the control roller 6 and the third roller 7 pivot successively into the starting positions according to FIG. 1 for receiving the empty winding core 2a.
