Device for handling workpieces, in particular processing products of a cutting metal sheet processing operation, and mechanical arrangements having such a device

A device for handling workpieces, comprising:

• a carrier structure;
• a pair of two-armed pivot levers, each comprising a first lever arm and a second lever arm arranged at an angle relative to the first lever arm, wherein each first lever arm forms a retention member;
• two retention member bearings, each of which is formed by a pivot bearing and each of which movably supports one of the first lever arms on the carrier structure such that the first lever arm can be pivoted from a non-operative pivot position into an operative pivot position and vice versa;
• a retention member drive including a drive motor;
• and
• two retention member transverse guide devices, each of which is arranged to guide a respective one of the first lever arms;
• wherein
• the drive motor is configured to move the retention member transverse guide devices relative to the first lever arms and the pivot bearings with a lifting movement along a lifting axis, wherein the retention member transverse guide devices are moved into an operative lifting position or into a non-operative lifting position;
• the retention member transverse guide devices are configured to guide the first lever arms movably supported by the pivot bearings, to carry out, due to the lifting movement of the retention member transverse guide devices into the operative lifting position or into the non-operative lifting position, a transverse movement in a direction transverse to the lifting axis, the first lever arms thus being pivoted into the operative pivot position associated with the operative lifting position of the retention member transverse guide devices or into the non-operative pivot position associated with the non-operative lifting position of the retention member transverse guide devices, wherein the first lever arms in the operative pivot position can engage behind an edge of a workpiece whereas the first lever arms in the non-operative pivot position cannot engage behind an edge of a workpiece,
• each of the retention member transverse guide devices includes a guide roller to guide the associated first lever arm during the transverse movement thereof and the retention member transverse guide devices further have a common guide roller, the guide rollers of the retention member transverse guide devices and the common guide roller being rotatably supported on a common guide sliding member of the transverse guide devices, wherein the guide rollers of the retention member transverse guide devices are configured to act upon the second lever arms when the retention member transverse guide devices perform the lifting movement into the operative lifting position and, thus, to pivot the first lever arms out of the non-operative pivot position into the operative pivot position and wherein the common guide roller is configured to act upon the second lever arms when the retention member transverse guide devices perform the lifting movement into the non-operative lifting position and, thus, to pivot the first lever arms out of the operative pivot position into the non-operative pivot position, and
• the drive motor is further configured to move the pivot bearings together with the first lever arms, which are pivoted into the operative pivot position, and the retention member transverse guide devices, which are moved into the operative lifting position, with a lifting movement along the lifting axis.
