Definitions

  • the invention relates to a device for the continuous reeling or rewinding of a paper web on a winding core, with a base frame, with rotary bearing receptacles located at the winding point, which are equipped with a drive and are intended for the opposite free ends of the winding core, a position-changeable pressure roller for the application to the peripheral surface of the winding core or the wound paper roll, a cutting device for cutting the paper web, a device for moving the wound winding core away from the rotary bearing receptacles, a device for applying the cut paper web to an empty winding core, and with a device for Enter an empty winding core in the rotary bearing holder.
  • Such a device is known from DE-OS 36 30 744.
  • a pressure arm is used, on the free end of which a deflection roller is attached.
  • This pressure arm can be moved between an upper and lower position, so that the path curve of the pressure arm runs between the pressure roller and the winding core winding the paper web.
  • the paper web is guided around the pressure arm such that in the lower position of the arm and in the open position of the pressure roller unit, the paper web is held by the arm below a gap for the paper web.
  • a knife bar located on the pressure roller unit produces a longitudinal cut that is approximately 150 mm from the edge of the paper web.
  • a stream of compressed air generated in the base draws the strip onto the empty winding core.
  • the knife bar then moves across the entire paper web, so that the web is completely drawn onto the winding core.
  • the invention has for its object to provide a device of the type mentioned, in which an optimal transition of the winding process from the full paper roll to a new, empty winding core is made possible in the sense of a continuous winding or rewinding process.
  • the winding process of the paper web on the empty winding core can be carried out in the known manner without additional aids, i.e. the removal movement of the winding core provided with the paper roll is used to shift the incoming paper web, in this way in Relation to the rotary bearing receptacles that when the empty winding core is inserted, its circumferential surface largely comes into free contact with the paper web approaching the paper roll.
  • the winding core is not supported by support and auxiliary contact rollers or locking rollers, but is freely immersed in the paper web, which has a positive effect on the winding process.
  • an empty winding core inserted into the rotary bearing receptacles even deflects the paper web wound onto the paper roll, so that the empty winding core already touches the paper web before it is finally inserted into the rotary bearing receptacles, with the result that the paper web is increasingly used until it is finally inserted into the rotary bearing receptacles, wraps around the empty winding core and, due to the resulting friction, the Takes the winding core along the circumference and can set it in rotation. This further promotes the start-up process.
  • the device for moving the wound winding core is expediently designed as a swivel arm.
  • This swivel arm is provided with two holding forks for the opposite free ends of the winding core.
  • This pivoting movement makes it possible in a particularly simple manner to carry out the desired displacement of the paper roll while maintaining the wall tension while the paper web continues to run.
  • this device for moving the wound winding core is provided with a drive motor (auxiliary motor).
  • an edge strip is cut lengthwise by the cutting device and then separated from the paper web by a blowing device and placed around the rotating empty winding core, after which a transverse cutting of the entire paper web takes place by a transverse movement of the cutting device. It is advantageous to arrange this cutting device in the middle with two parallel cutting edges and thus to cut out the corresponding strip from the middle of the web, since this ensures a safer winding with the subsequent transverse cutting.
  • Rotary bearing receptacles 12 for receiving freely protruding bearing ends 14 of winding cores 16 (drum).
  • a swivel arm 18 downstream of the paper path, which swivel arm can be swiveled about a lower swivel axis 20 from a dash-dotted position shown in the drawing into the extended position by means of a hydraulic or pneumatic cylinder 22.
  • This pivot lever 18 is of course located on both sides of the winding core and is provided with a receiving fork 24, the left fork part 26 is pivotally arranged by means of a hydraulic or pneumatic cylinder 28, which is indicated by solid and dash-dotted lines.
  • the free bearing ends 14 of the winding core 18 are placed on a tray 30, on which the wound winding cores can be rolled with a paper roll 32 for dispensing them, namely from the position indicated by B into the position indicated by D marked place.
  • a winding core feed device Upstream of the winding station A there is a winding core feed device with a first lever 36, which is articulated at 38 and can be moved from the extended position into the dash-dotted position by a hydraulic or pneumatic cylinder 40.
  • the winding core feed device 35 has a second lever 44 articulated on the first lever 36 at 42, at the free end of which there is a fork 46 with a pivotable part 48.
  • This lever arrangement of the winding core feed device 35 is of course located on both sides of the winding core in order to be able to grasp the respective ends 14 of the winding core.
  • the second lever 44 can be pivoted about the axis 42 by means of the hydraulic or pneumatic cylinder 41, as is shown in two positions by dash-dotted lines.
  • a further pivot lever 50 which can be pivoted about a pivot axis 54 from a dash-dotted position into an extended position by means of a hydraulic or pneumatic cylinder 52.
  • a pressure roller 56 which first presses the paper web against the winding core 16 and rests on the surface of the resulting winding (paper roll 32) during winding in order to be able to ensure a perfect winding process.
  • a tip cutter 58 on the lever 50 for longitudinal and transverse cutting of the paper web.
  • a blowing device 60 is located downstream of the winding core 16 in the winding station A.
  • the winding core feed device 35 now brings an empty winding core 16 into the rotary bearing receptacles 12.
  • the winding core 16 plunges into the course of the paper web P "'and deflects the paper course into the course P" ".
  • the running paper web can already rub against the winding core set in rotation, which is particularly feasible with reduced web speed.
  • the pressure roller 56 is placed on the circumference of the empty winding core 16, and the tip cutter 58 cuts either in the middle or at the edge an approximately 10 cm wide strip by slitting, which strip is separated by the blowing device 60 and placed around the winding core 16 , which is possible by immersing the winding core in the paper web directly without additional measures.
  • the tip cutter After the strip of the paper web has been transferred onto the winding core 16, the tip cutter immediately cuts the strip "wide", whereby the paper web is completely wound onto the empty winding core. The web speed can then be increased again, and the full roll of paper can be delivered from location B to location D and from there.
  • This process is repeated every time a full roll of paper has been made.
  • Such a process is both in terms of general reeling as well possible with regard to a roll over.
  • a device connects to a calender or supercalender.
