Punching device with gripper unit

摘要

A punching device is provided for processing samples applied to a sample card comprising at least one punching head with a punch and a lower die, the punch being movable between a resting position and a punching position. The punching head has a receiving opening into which a sample card can be introduced by a movable gripping unit, and a punching drive, which drives the movement of the punch between the resting position and the punching position. A piece of sample punched out from the sample card can be discharged at an outlet opening of the lower die into a receiving recess of a receiving container. The gripper unit comprises a sample card gripper and a receiving container gripper which are moveable by a drive unit in three main directions that are orthogonal to one another.
