Apparatus and Method for the Stacking of Stackable Parts
First Claim
1. An apparatus for the stacking of stackable parts with a conveyor station with at least one conveyor on which the parts may be transported separately, and at least one stacking container in which the parts may be stacked, wherein, to transfer the parts between the conveyor station and the stacking container, there is provided a stacking device which takes parts from the conveyor of the conveyor station and stacks them in the stacking container, and wherein the stacking device has at least one pair of stacking robots containing two stacking robots operating independently of one another, wherein the stacking robots alternately or simultaneously take up parts from the conveyor and are so controlled by a control unit that a first and/or second stacking robot takes up at least one part from the conveyor, while simultaneously the second and/or first stacking robot transfers to or stacks in the stacking container used by both stacking robots a part already picked up, while with simultaneous taking up of parts by the first and second stacking robots, simultaneous stacking in the common stacking container is effected at two different stacking places.

Abstract
An apparatus for the stacking of stackable parts with a conveyor station with at least one conveyor on which the parts may be transported separately, and at least one stacking container in which the parts may be stacked wherein, a stacking device is provided, which takes parts from the conveyor of the conveyor station and stacks them in the stacking container. The stacking device has at least one pair of stacking robots operating independently of one another, wherein the stacking robots alternately or simultaneously take up parts from the conveyor and are so controlled by a control unit that a first and/or second stacking robot takes up at least one part from the conveyor, while simultaneously the second and/or first stacking robot transfers to or stacks in the stacking container used by both stacking robots a part already picked up.

8. A method for the stacking of stackable parts comprising the steps of:
-
movement of parts placed separately on at least one conveyor; taking up of the parts from the conveyor by means of a pair of stacking robots containing two stacking robots operating independently of one another, wherein a first stacking robot takes up a part from the conveyor, while simultaneously a part already taken up is stacked in a stacking container by a second stacking robot operating independently of the first stacking robot, or is transferred to the stacking container, or at least another part is taken up from the conveyor, wherein, in the case of transfer, this is effected by means of a transfer movement which includes swivelling of the second stacking robot; transfer of the part taken up by the first stacking robot to the stacking container, which in the case of stacking or transfer has already been used by the second stacking robot, by means of a transfer movement involving swivelling of the first stacking robot, while at the same time the second stacking robot stacks the other taken-up part in the stacking container, or returns unloaded, or transfers to the stacking container; and stacking in the stacking container of the part taken up by the first stacking robot, while at the same time the second stacking robot takes up another part from the conveyor, returns unloaded, or stacks the other taken-up part in the same stacking container used for stacking by the first stacking robot, but at a different stacking point. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
