Definitions

  • the invention relates to the field of sheet processing. It relates to an apparatus and method for breaking at least one benefit limited by a stripping line from a sheet while the sheet is being conveyed.
  • the apparatus includes a breakout means for breaking at least one benefit from a sheet in a breakaway zone.
  • the apparatus includes a feed device for feeding the sheet in a feed direction to the breaking-out device. The breaking-out device deflects the sheet out of the feed direction, forming the breaking zone.
  • the break-out zone thus corresponds to that area in which the sheet is deflected out of the feed direction while the benefits break out.
  • the breaking away of benefits from a bow is referred to in professional circles alsohereby constitutrennung.
  • the basic principle, according to which these devices are constructed, is to obtain by mechanical means a deflection or bending of the bow.
  • the mechanical means act exclusively on arc areas outside the benefits, which form the later sheet waste.
  • Ausbrechrollen instead of fingers or circumferential Entgittanss-belt also lowerable Ausbrechrollen are known, which are lowered upon arrival of a bow on this.
  • the Ausbrechrollen form in the lowered position with counter-rollers on which rests the sheet, a nip, which is arranged below the conveying plane of the sheet.
  • the stripping rollers introduce the sheet into the clamping gap and deflect it in this way from the Zu arturgi down.
  • the Ausbrechrollen act exclusively on the side and between the benefits in the conveying direction continuously extending arcuate webs of the grating.
  • the above-mentioned devices have the disadvantage that the sheet must have at least one continuous area in the conveying direction, in particular web, outside the benefits on which said mechanical Means for the purpose of deflection of the sheet from its feed direction can act permanently.
  • the sheet should be optimally utilized and the sheet waste be kept as low as possible by a clever arrangement of the benefits.
  • the benefits on the sheet can be placed in a toothed arrangement. This may be the case in particular with asymmetrically designed benefits. As a result, no continuous arc regions or webs are formed in the conveying direction. The arch areas are rather broken in the conveying direction by benefit sections.
  • the device and the associated method have the disadvantage that the clocked control of Ausbrechrollen is quite complex and must be adapted in each case in a new series of sheets with differently designed benefits. Furthermore, the clocking, discontinuous "up” and “down” movement of the stripping rollers limits the processing speed. Furthermore, the maintenance and wear is increased in fast strokes.
  • the publication DE 601 19 288 T2 now describes an "up” and “down” movable removal roller, which is arranged following a pair of rollers.
  • the pair of rollers comprises a top and bottom roller, which form a conveying gap through which the sheet is conveyed in the feed direction in the breaking zone.
  • the removal roller is controlled so that it is moved at the exit of the leading edge of the sheet from the conveying nip of the pair of rollers down.
  • the removal roller hits the front edge of the sheet, which is part of the curved grille, and deflects it downwards.
  • the removal roller hits in the lower end position on the lower roller of the roller pairing and forms with this another, arranged below the conveying plane conveying gap in which the deflected down, front sheet edge is clamped.
  • the benefits are now broken out of the deflected bow and passed above the removal roller. After completion of the Ausbrechvorganges the removal roller is raised back to its upper end position.
  • the device has the disadvantage that a comparatively complicated mechanism for lowering and lifting the removal roller must be provided and operated. Further, since the lifting speed of the removal roller are limited, the processing speed is limited here as well.
  • the device should be simpler to construct and operate. Furthermore, the device should allow high processing speeds. In particular, discontinuous movements of parts of the breakout such. B. strokes are avoided.
