Abstract

A blank separating device includes at least one upper blank separating module, the at least one upper blank separating module having a first relief, the first relief comprising at least three separating elements and/or contact elements, each including an operative surface and/or contact surface. The at least three operative surfaces and/or contact surfaces are individually arrangeable to at least three different distances in a vertical direction with respect to a carrier plate within which the at least three separating elements and/or contact elements are mounted. The blank separating device further includes at least one lower blank separating module that has a second relief comprising a plurality of supporting elements. The second relief matches, at least in complimentary vertical positioning, the first relief of the at least one upper blank separating module.

First claim

The invention claimed is:

1. A blank separating device comprising:
at least one upper blank separating module, the at least one upper blank separating module having a first relief, the first relief comprising at least three separating elements and/or contact elements, each of the at least three separating elements including an operative surface and/or contact surface, and the at least three operative surfaces and/or contact surfaces being individually arrangeable to at least three different distances in a vertical direction with respect to a carrier plate within which the at least three separating elements and/or contact elements are mounted, and
at least one lower blank separating module having a second relief comprising a plurality of supporting elements,
wherein the plurality of supporting elements of the second relief include at least three supporting elements for bracing blanks or scrap pieces, and the at least three supporting elements are arrangeable to three different distances with respect to a guide carrier of the at least one lower blank separating module, the guide carrier of the at least one lower blank separating module being arranged in the vertical direction with respect to the at least three supporting elements,
wherein the at least one lower blank separating module comprises at least one lower separating tool comprising at least two supporting elements of the at least three supporting elements, and the at least two supporting elements of the at least three supporting elements are configured as supporting pins, and
wherein the at least two supporting elements of the at least three supporting elements can be arranged in a position as a function of a rigidity of the contact surfaces of the upper blank separating module.

2. The device according to claim 1 , wherein, in a separating position, a magnitude of a difference of two distances of at least two supporting elements of the at least three supporting elements corresponds to a magnitude of a difference of two distances of at least two operative surfaces and/or contact surfaces.

3. The device according to claim 1 , wherein the at least one upper blank separating module and/or the at least one lower blank separating module can be transferred from an open position into a separating position.

4. The device according to claim 3 , wherein:
the at least three separating elements and/or contact elements of the at least one upper separating module comprise multiple separating elements configured as separating pins, and
the separating pins are arranged in a separating pin matrix.

5. The device according to claim 1 , wherein one of the at least three supporting elements of the at least one lower blank separating module is configured as a conveyor belt.

6. The device according to claim 1 , wherein the at least three separating elements and/or contact elements of the at least one upper blank separating module comprise at least one separating element and at least one first contact element and at least one second contact element.

7. The device according to claim 1 , wherein the first relief is formed by multiple surface areas which can differ and/or differ from one another in the vertical direction.

8. The device according to claim 1 , wherein:
the first relief is formed by the operative surfaces of the upper blank separating module by multiple surface areas being arranged differently in the vertical direction, and
the multiple surface areas are formed by multiple elements situated next to one another and/or the operative surfaces and/or contact surfaces of the multiple elements situated next to one another.

9. A method for separating blanks, the method comprising:
separating, using at least one blank separating device, at least one partial blank pile from a pile and/or a ream of sheets, wherein, during the separating, at least one lower blank separating module and at least one upper blank separating module are brought into engagement, the at least one upper blank separating module forming a first relief including a plurality of upper elements having at least three operative surfaces and/or contact surfaces, the at least three operative surfaces and/or contact surfaces being individually arrangeable to be positioned at least three different distances with respect to a carrier plate within which the plurality of upper elements are mounted, the at least one lower blank separating module including a second relief comprising a plurality of supporting elements,
wherein the plurality of supporting elements comprising the second relief include at least three supporting elements for bracing blanks or scrap pieces, and the at least three supporting elements are arrangeable to three different distances with respect to a guide carrier of the at least one lower blank separating module, the guide carrier of the at least one lower blank separating module being arranged in the vertical direction with respect to the at least three supporting elements,
wherein the at least one lower blank separating module comprises at least one lower separating tool comprising at least two supporting elements of the at least three supporting elements, and the at least two supporting elements of the at least three supporting elements are configured as supporting pins, and
wherein the at least two supporting elements of the at least three supporting elements can be arranged in a position as a function of a rigidity of the contact surfaces of the upper blank separating module.

10. The method according to claim 9 , wherein, when at least two blanks on a sheet are directly connected and/or joined via holding points, at least one of the first relief of the at least one upper blank separating module or the second relief of the at least one lower blank separating module, during the separating, at least temporarily, includes three planes.

11. The method according to claim 9 , wherein, during the separation of crosspieces and/or offcut pieces, at least one of the first relief of the at least one upper blank separating module or the second relief of the at least one lower blank separating module, during the separating process, at least temporarily includes two planes.
