Definitions

  • the present invention relates to a device for supporting a roll with web material according to the preamble of claim 1 (DE-C-310 813).
  • the U.S. U.S. Patent No. 4,433,816 discloses a wire roll holder in which a full wire roll is received in a rack and passed over multiple spools for processing.
  • the stability of the frame is a critical point, especially at high unwinding speeds; continuous, trouble-free unwinding is not guaranteed at all unwinding speeds.
  • a swiveling unwinding device for large rolls is known from German utility model no. 89 12 231.3.
  • a stand made of two plates is rotatably mounted on a base plate and receives the shaft of a roller. The base plate cannot be moved.
  • EP-A-0 391 061 relates to a system for loading the paper roll carrier of a rotary printing press with a paper roll.
  • a paper roll mounted on a transfer table can first be brought into a rough setting position and then into a fine setting position.
  • adjustment columns can be moved horizontally along guide rails in order to ensure exact alignment of the paper roll before it is transferred.
  • a printing unit can also be arranged in a printing press above a respective individual unwinding device.
  • a roll included in the unwinder Web material is fed upwards into the printing unit during unwinding.
  • there may not be enough space next to the unwinding device for inserting and removing the roll (DE-C-310 813 or GB-A-1 214 641).
  • the invention has for its object to improve the handling of the web supply on an unwinding device for a printing press.
  • An unwinding device constructed according to the present invention makes it possible to insert the roll from the front / operator side.
  • the roll of web material is loaded onto the carrier outside the frame and moved into the frame with the carrier.
  • the guide rails on the frame support the carrier in a position in which the roller is coaxially aligned with the roller brake attached to the frame.
  • a variety of interchangeable brackets can be used in a printing machine, with the guide rails in each unwinder ensuring that each bracket is supported in a position where the associated roller is coaxial with the associated brake.
  • a printing machine part 10 constructed according to the present invention comprises an unwinder 12 and a printing unit 14.
  • the unwinder 12 comprises a frame 16 and a carrier 18.
  • the carrier 18 is in and out of the frame 16 movable, and the printing unit 14 is arranged over the frame 16.
  • the printing unit 14 comprises a pair of printing rollers 20 for printing on a material web 22 which is moved by the unwinder 12 through the printing unit 14.
  • the frame 16 generally has a rectangular structure.
  • a pair of spaced frame members 24 and 26 define the front / operator side of the frame 16.
  • a single frame member 28 defines the rear / transmission side of the frame 16.
  • a plurality of cross members 30 attach the frame members 24 and 26 to the frame member 28.
  • the frame members 24 and 26 have respective edge surfaces 32 and 34 which are opposite each other over the front / operator side of the frame 16. The edge surfaces 32 and 34 thus define an opening through which the carrier 18 can be moved.
  • a pair of clips 36 are attached to frame members 24 and 26 on the front / operator side of frame 16. These brackets 36 extend within the opening between the edge surfaces 32 and 34.
  • a pair of guide rails 38 are attached with their front end to the brackets 36 and with their rear end to the frame part 28. The guide rails 38 are parallel to one another and are located between the edge surfaces 32 and 34, which determine the opening on the front / operator side of the frame 16.
  • a number of web guide rolls are mounted across the inside of the frame 16, namely an upper guide roll 40, a lower guide roll 42 and a compensating roll 44.
  • a compensating mechanism 46 of known design is associated with the compensating roll 44.
  • the compensating mechanism 46 effects a limited rotational movement of the compensating roller 44 around a hub 48 in a known manner.
  • a brake 50 is attached to the frame part 28 next to a brake opening 52 on the rear / transmission side of the frame 16.
  • the brake 50 is functionally connected to the compensating mechanism 46 in a known manner.
  • the carrier 18 holds a roll 60 of web material 22.
  • the roll 60 has a roll core 62.
  • the carrier 18 includes a pair of spaced-apart support frame members 64 and 66. Each of the support frame members 64 and 66 includes one A pair of roller bearings 68 in which an end part of the roller core 62 is rotatably supported.
  • a roller core lock 70 is rotatably supported in the support frame part 64. The roller core lock 70 can be moved into and out of a contact position with the roller core 62 in order to secure the roller core 62 against axial movement on the carrier 18.
  • a side stop mechanism 72 is also attached to the support frame member 64. The side stop mechanism 72 regulates the axial position of the roller core 62 on the carrier 18.
  • the roller core lock 70 and the side stop mechanism 72 are of a known design and cooperate with one another and with the roller core 62 in a known manner.
  • the carrier frame parts 64 and 66 also carry a guide roller 74 which extends transversely to the carrier 18.
  • Carrier 18 also includes lift openings 80 and bearing surfaces 82 and 84.
  • the bearing surfaces 82 on the left side of carrier 18, as shown in FIG. 1, are from the horizontal lower peripheral surfaces of the Carrier frame parts 64 and 66 determined.
  • the bearing surfaces 84 on the right side of the carrier 18 are determined by the angled lower edge surfaces of the plates 86, which are fastened to the carrier frame parts 64 and 66.
  • the carrier 18 is moved into and out of the working position, as shown in FIG. 1.
  • the roll 60 with web material 22 is first loaded onto the carrier 18 outside the frame 16 by the roll core 62 being clamped onto the roll bearings 68 by means of the roll core lock 70.
  • the front end portion 90 of the web material 22 is then wound around the guide roller 74 and glued to the right side of the roller 60, as shown in FIG. 1. The front end portion 90 of the web material 22 is thus in an accessible position.
  • the carrier 18 is moved by the fork arms 92 of a forklift 96 or the like through the opening in the front of the frame 16 and lowered onto the guide rails 38.
  • the roller 60 is thus moved parallel to its axis and parallel to the axes of the printing rollers 20 in the frame 16 of the printing unit 14. Since the roller core 62 extends coaxially with the brake opening 52 when the carrier 18 rests on the guide rails 38, the side stop mechanism 72 can then be actuated as required to move the roller core 62 through the brake opening 52 into contact with the brake 50.
  • the plates 86 are mounted on the support frame parts 64 and 66 in positions in which the coaxial alignment of the roller core 62 and the brake opening 52 is ensured, when the carrier 18 rests on the guide rails 38.
  • a plurality of supports of the same construction as the support 18 are therefore interchangeable in the frame 16 and other uniform frames.
  • the front end part 90 of the web material 22 can be moved along the distance shown between the printing cylinders 20 in the printing unit 14 or alternatively along a distance that bottom right out of the frame 16 into another Printing unit (not shown) runs, are threaded. While the web material 22 is moved by the printing rollers 20 in the longitudinal direction through the printing unit 14, it is unwound from the roll 60. The tension in the web material 22 between the roll 60 and the printing unit 14 is controlled by the compensating roller 44, which has a direct effect on the web 22, and by the brake 50, which has a direct effect on the roll core 62. When roll 60 of web material 22 is used up, carrier 18 can be removed and another roll 60 inserted, or carrier 18 can be replaced with another carrier containing another roll.
