1. A device for separating blanks from a pile and/or a ream of sheets, the device 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 element pins, each including an operative surface, the multiple separating element pins being arranged in a separating element matrix, the multiple separating element pins being arrangeable in an activated position or a deactivated position, at least one separating element pin of the multiple separating element pins in the activated position having a first distance with respect to a carrier plate, and at least one separating element pin of the multiple separating element pins 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 a blank shape and/or a number of blanks on a sheet,
that, for removing crosspieces, the at least one upper blank separating tool has at least one operative element, adapted to boundary lines of the blanks to be processed, when offcut pieces configured as crosspieces are present on a sheet, and
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 one blank separating tool carrier, and at least one second contact surface at a second distance with respect to the at least one blank separating tool carrier, and that the at least one first contact surface and/or the at least one second contact surface can be arranged at least relative to one another in at least one further position.
