Definitions

  • the invention relates to a method and a device for changing Pallets for sheet stacks with continuous delivery of sheets to the stacking point. Furthermore, the invention relates to a release jaw for a such device.
  • a known method for making such a pallet change in Continuous promotion of bow to the stacking point is known from DE 36 16 470 C2 known.
  • the method disclosed there also shows the closest State of the art.
  • a separating finger of the in the conveying direction of the arc back side of the sheet stack between the first sheet pile and the subsequently fed bow inserted.
  • This separation finger is now lowered more slowly than the first sheet stack, so that a gap between the nachge elaborateten, lying on the release finger Forming the bow and the first sheet pile.
  • This gap is now a first Jaw inserted.
  • the separating finger from the gap taken out again, to the top of the pile of nachge redesignten bow up and there again from the back side between the next subsequent sheet and the stack of sheets pushed on the first jaw.
  • the release finger is lowered again slower than the first jaw with the stack on it, so that there is another, second gap between the first jaw and the one located on the separating finger Bow forms. In this second gap, a second jaw is inserted. Now it will be between the first and the second jaw Sheet pile sandwiched between the jaws by the jaws be moved towards each other.
  • the pallet is carried away with the first sheet pile.
  • a new pallet is placed under the auxiliary table.
  • the Auxiliary table again from the gap below the held by the jaws Bow pile pulled out, so that of the jaws held stack of sheets on the arranged below the auxiliary table pallet can be lowered.
  • the clamping of the solved by the jaws clamped sheet pile by the distance the jaws is enlarged again to each other.
  • This object is achieved by a method according to claim 1 or by a device according to claim 11 or a separating jaw according Anpruch 12th solved.
  • the advantages of the invention are, in particular, that due to the invention an entrapment of a stack of bows no longer necessary is. Rather, due to the invention, the sheet is sucked to the separating jaw, so that no force on the sheet pile or on the single sheet is necessary in the stacking direction. Beyond that thanks to the invention, the jaws superfluous, which is a considerable simplification of the method and also according to such a method represents working device.
  • the invention takes advantage of a special property of a sheet pile, the due to the precision of today's cutting devices on its side surfaces practically forms a closed, almost smooth surface. These The fact makes it possible to suck in such a stack of sheets from the side.
  • a preferred embodiment of the method according to the invention is characterized in that in the method according to claim 1 the Generating the gap between the first sheet stack and the following Arc is obtained by the separating finger slower against the Stacking direction of the first
  • Sheet pile is lowered as the first sheet pile itself. This way creates the gap in a simple way.
  • a further preferred embodiment of the method according to the invention has the step, the same time with or after the introduction of the release jaw in the is taken from the gap generated by the separating finger gap of the separating finger from the gap.
  • This embodiment allows, for example, that the separating finger is not in a recess in the separating jaw must be performed. Alternatively, it is possible to guide the separating finger in a recess of the separating jaw, so that the Separating jaw can be pushed into the gap, while also the separating finger still in the gap.
  • a particularly preferred embodiment of the invention is characterized that provided in the separating jaw the subsequent arc facing openings are through which the subsequent bows are sucked by this Openings gas, preferably air, is sucked.
  • the Separating jaw for example, be designed as a hollow body, in which hollow body a vacuum is generated. The hollow body is then next to the openings in his Wall also provided with openings through which the hollow body to the Suction side of a fan or other vacuum source is connected.
  • the separating jaw sucks the bottom arch at its bottom.
  • this floor is additionally fixed.
  • the invention is characterized in that in one already in the effective range of Trennbacke from subsequent sheets formed beginning of a new stack of Back of this new stack is sucked by the release jaw. Furthermore The suction of the back of the new stack can also cumulatively to that Suction of the bottom provided in the area of the back of the new stack become.
  • the latter embodiment promises additional and maximum fixation of the new stack on the separating jaw thus working.
  • the release jaw is included preferably formed as an angle.
  • the separating jaw preferably has two at right angles disposed surfaces, each having openings through which a negative pressure in the region of these surfaces is generated. The one surface is arranged parallel to the plane of the arc, while the other surface is arranged parallel to the back of the new stack.
  • Another preferred embodiment of the method according to the invention is characterized in that during the introduction of the auxiliary table at least one band arranged on its surface is activated in such a way that the relative velocity between the band and the lowest bow of the subsequent arc is substantially equal to zero. This way too when introducing the auxiliary table in the through the inventive release jaw formed gap markings at the bottom of the new stack or at the Underside of the bottom arc of the post-conveyed bow avoided.
  • a particularly advantageous and particularly preferred embodiment of Invention is characterized in that during the introduction of the auxiliary table Gas, preferably air, is blown against the underside of the belt. To this Way, the friction between the auxiliary table and the belt is reduced. It is particularly preferred if that on the surface of the auxiliary table arranged band to avoid a relative speed of auxiliary table surface and bottom following bow is formed as a cloth.
