Definitions

  • the invention relates to a punch from the contour punching of a precut benefit stack by means of a punching iron, with a feed plate for supporting the stack of benefits, a feeding device for feeding the stack of benefits to the punching iron, a stamping the benefit stack against the punching iron punch and a means for conveying the finished punched pile of sheets.
  • the punch mentioned is used in particular for punching a stack of useful items formed from a large number of printed labels lying one above the other.
  • This benefit stack of foliated material consists in particular of printed paper.
  • the individual labels are made of plastic, in particular plastic film. This is a very flexible material that also charges so that individual sheets of the benefit stack adhere to each other.
  • the precut benefit stacks are cuboidal.
  • the punch serves to give benefit stacks their finished contour. This is how labels become Usually printed on large sheets that are up to several hundred stacked over a thousand on top of each other. Such printing sheet stack are pre-cut longitudinally and transversely, with a variety of benefit stacks be formed, which are isolated.
  • a punched iron with a closed contour is used for producing the finished labels. After the respective benefit stack by means of the feeder under the Stanzeisen is supplied, the benefit stack by means of a punch against pressed the punching iron and punching performed. Subsequently the finished-punched benefit stack is carried away.
  • the punching iron passes through a counter-pressure plate, which in Active connection with the benefit stack on its side facing away from the stamp Page can be brought.
  • a counter-pressure plate By means of this counter-pressure plate can the finished punched Use stack pressed out of the punching iron and by means of separate means be carried away.
  • a punch of the type mentioned is known from DE-91 15 347 U.
  • the feeder consists of lateral, essentially vertical guide jaws, which, based on the feed direction of the Feeding device in the region of its rear end einschwenkbare Have transport jaws, which laterally or end the pre-cut Benefit stacks are associated with cross-tabs.
  • This transporting jaws is the only task, one after the cut due to the Wedge shape of the cutting knife parallelogram shifted in itself to take precut benefit stack in the area of the lowest sheet layers and to advance in the direction of the punch, being against the leading oblique surface of the precut benefit stack an alignment stop is moved to align the benefit stack in its cuboid shape.
  • the Aligned benefit stack is further by means of the transport jaws to the Advanced punch.
  • a device for punching a stack of Blattgut Good is also off WO 01187556 A known.
  • Object of the present invention is a punch of the above to provide a type of automatic loading of the punch, i. automatic transfer of the benefit stack into the area of the stamp, with simple structural effort and process-safe is possible.
  • the feeder a lifting and has lowerable support for the benefit stack, to reach under the Benefit stack in the area of its benefit stack in the feed direction leading lower edge, means for lifting the support with their Recording surface for the benefit stack on the level of the receiving surface of the Stack are provided.
  • This design of the feeder for solving the problem of automatic loading of the punch is therefore of great advantage because as a result of lifting the leading lower edge of the benefit stack the lower sheet layer of the stack is not on a ridge of the stamp in the area the punching line can get stuck. It is thus always ensured that the precut benefit stack properly supplied to the stamp can; This is crucial for the continuous operation of the punch.
