Device and method for separating blanks

A device for ream-wise and/or pile-wise separating blanks from a pile and/or a ream of sheets, comprising at least one lower blank separating module and at least one upper blank separating module, the at least one upper blank separating module comprising an upper separating tool, the upper separating tool comprising multiple separating elements configured as separating pins, each including an operative surface, the separating elements being arranged in a separating element matrix, the multiple separating elements being arrangeable in an activated position or a deactivated position, a separating element in the activated position having a first distance with respect to a carrier plate, and a separating element in the deactivated position having a second distance with respect to the carrier plate, characterized in that the at least one upper blank separating module additionally comprises at least one upper blank separating tool, that the at least one upper blank separating tool is adapted as a function of the blank shape and/or the number of blanks on a sheet,

• that, for removing the crosspieces, the at least one upper blank separating tool has at least one operative element, adapted to the boundary lines of the blanks to be processed, when offcut pieces configured as crosspieces are present on a sheet, and/or
• that, for separating blanks arranged directly next to one another on a sheet, the at least one upper blank separating tool includes at least one first contact surface at a first distance with respect to at least the blank separating tool carrier, and at least one second contact surface at a second distance with respect to at least one blank separating tool carrier, and that that the at least one contact surface and/or the at least one second contact surface can be arranged in at least one further position.

A method for separating blanks comprising at least one blank separating device, during a separation process at least one lower blank separating module and at least one upper blank separating module being brought in contact, the at least one upper blank separating module comprising an upper separating tool comprising multiple separating elements configured as separating pins, each including an operative surface, the separating elements being arranged in a separating element matrix, the multiple separating elements being positioned in an activated position or a deactivated position, and at least one partial blank pile being separated from a pile and/or a ream of sheets by means of the at least one blank separating device, characterized in that the offcut pieces and/or the blanks are additionally separated by means of at least one upper blank separating tool, that the at least one upper blank separating tool is adapted as a function of the blank shape and/or the number of blanks on a sheet,

• that, for removing the crosspieces, the at least one upper blank separating tool has at least one operative element, adapted to the boundary lines of the blanks to be processed, when offcut pieces configured as crosspieces are present on a sheet, and/or
• that the blank separating device can separate and/or separates blanks situated directly next to one another on a sheet by means of at least one first contact surface and at least one second contact surface of the at least one upper blank separating tool, and that the at least one first contact surface and/or the at least one second contact surface are movable for this purpose in the vertical direction and/or in the direction of a surface normal to one of the contact surfaces.
