Definitions

  • the invention relates to a breaking-out device according to the preamble of claim 1 or claim 7 and a use-separating device according to the preamble of claim 2 or claim 8, in particular for a sheet punching and embossing machine, as well as a method of setting up such a device according to claims 10 and 11 ,
  • punching As punching the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds. Also the practices practiced in print finishing, such as punching with punch, corner punching and register punching are counted to this area.
  • the punching takes place against a punching pad or against stamp, in some cases it is also shearing operations.
  • Packaging materials made of paper, cardboard, cardboard or corrugated board are mainly punched in sheet format. When punching but also creasing lines or blind embossing can be introduced into the benefit. This complex process makes it indispensable to punch the sheets individually.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 known.
  • the two tables are equipped with cutting and scoring tools or corresponding counter tools with which punched out of the cyclically guided between the table surface sheets the benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designatedWhentrenn arthritis.
  • a stripping tool usually consists of an upper tool and a lower tool, which are each equipped with Ausbrechrochen.
  • the number of stripping pins required varies from less than 10 to more than 500, depending on the die pattern of the die assembly. With a large number of stripping pins, the time required to set up the tool is very high, which affects the productivity of the sheet punching and embossing machine.
  • the blanking tool must be created individually according to the die and the benefit distribution.

In the holes specially shaped Ausbrechune be plugged, which are held by spring force in the plates. This design allows the universal breakout tool to be modified and adjusted to the punching job with a simple operation without the additional use of tools. However, with a high number of stripping pins in the tool, a great deal of time is required for setting up, which affects the productivity of the sheet punching and embossing machine.

Both measures serve to reduce set-up times and increase productivity. However, with a large number of breakout pins, due to the manual positioning of the breakout pins in the upper tool, a high amount of time is still required.
  • ejector bodies are magnetically or electromagnetically connectable to a plate-shaped support means.
  • the ejector body can be quickly assembled into different contours and adapted to the punching pattern. Due to the dimensions of the ejection body, however, no arbitrary exact adaptation of theacitrenntechnikmaschines to the die and the benefit distribution is possible.
