Definitions

  • the invention relates to a device for applying reinforcement labels provided with a glue application to a web provided with transverse perforations, preferably to a web of bags connected to one another via the transverse perforations, with a device for tearing off the sections or bags connected to one another by the transverse perforations from the web.
  • Plastic film bags are made, for example, starting from a flat-lying tubular web made of thermoplastic material in that the tubular web is provided with transverse weld seams and next to these with transverse perforation lines, so that the individual bags can be torn off the web along the transverse perforation lines. If stacks of bags are to be formed from the bags, the individual bags must be torn off and stacked mechanically. In addition, it is often necessary to stick reinforcement labels to the web or the individual bags, which can form, for example, grip hole reinforcements or hanging tabs.
  • the object of the invention is therefore to provide a simply constructed and therefore economically producible device of the type specified at the outset.
  • the rotating segment therefore has a double function. On the one hand it presses the sticky note onto the sections of the web to be torn off and on the other hand it works Segment as an intermittent tear-off element on the web. Since the web conveyed at the conveyor belt speed is held between the inlet-side deflection rollers and the conveyor roller interacting with it, the segment rotating at a higher peripheral speed and interacting with the counter-pressure roller tears off the individual sections along the transverse perforation lines.
  • the segment for holding the glued papers is expediently provided with suction air openings or at least one suction air duct in its peripheral surface.
  • the suction air can be supplied to the suction air nozzles or suction air slots in the circumferential surface in the usual way by so-called rotary unions.
  • a knife edge is arranged which interacts with a rotating shear bar for separating the notes from a supplied sheet of paper.
  • peripheral surface of the segment interacts with a punch of a punching device rotating at the same speed.
  • the notes are to form tabs serving for stacking, they can be pressed on in the region of the trailing end of each section in such a way that they overlap the edge formed by the tear.
  • a suction belt conveyor conveying with its lower strand connects to the conveyor belt, below which a stacking belt conveyor is arranged, on the intermittently advanced stacking pins a lifting and lowering stamp needles the sections in such a way that the stacking pins Insert the note into the stacked holes punched into these.
  • a winding roll 2 is rotatably mounted in an unwinding device 1. From this winding roll 2, the web 3 is drawn off, namely by a plurality of lower endless belts 5, which are spaced next to one another and guided by rollers 4, and by upper rollers 6 which are spaced apart on an axis.
  • the web 3 itself consists of a chain of diaper bags which are connected to one another via perforation lines, not shown.
  • counter-rollers 7 are provided which interact with a segment 8. The latter has a suction channel 9 on the one hand and a knife edge 10 on the other.
  • This knife edge 10 cooperates with a rotating counter knife 11 in such a way that individual slips 14 are separated from a glued endless web 13 fed via a suction belt 12 and held by the suction channel 9 will.
  • a rotating punching device 15 is also assigned to the segment 8, through which holes are punched into individual pieces of paper 14.
  • the individual pieces of paper 14 are pressed onto a diaper bag 16 in cooperation with the counter-rollers 7.
  • rollers 7 and the segments 8 which are arranged parallel and at a distance from one another, run faster than the web itself at the moment in which the segments 8 come into contact with one another, a diaper bag 16 is torn off from the web through the segments 8 .
  • the segments 8 consequently serve, on the one hand, to tear off individual diaper bags 16 from the diaper bag chain track 3 and, on the other hand, to press reinforcement sheets onto individual diaper bags, for example.
  • the diaper bags 16 stuck with the note 14 are then removed from the tape guide 5 via an upper suction tape 17 and deposited by a depressor 18 onto the pins 19 of a stacking tape 20 in a manner known per se.
