  • Patent number: 9611102
    Abstract: A system creates streams of articles on a laning conveyor having differentiated lanes from groups of articles on a feed, the groups each including articles arranged in a grid including at least two rows. The system includes an end effector on a robot arm. The robot arm is configured to simultaneously lift all of the articles in all of the rows of one of the groups from the feed. The end effector has individually actuatable row portions corresponding to the locations of the articles in the groups. The end effector is configured to sequentially place the lifted articles of each of the rows on the laning conveyor in a given lane of the laning conveyor. Related end effectors and methods are disclosed.

  • Patent number: 7559737
    Abstract: A new type of pallet stacking assembly line. Two pick-and-place robots are used. The first robot has a relatively low position. The second robot is in an elevated position. A pallet dispenser dispenses a first pallet onto a pallet conveyor. The pallet conveyor then moves the first pallet to a first build position in front of the first robot. The first robot then begins picking products from a first pick position and stacking them on the first pallet. Once the products on the first pallet reach approximately half the finished height, the pallet conveyor carries the first pallet over to a second build position in front of the second robot. At the same time, the pallet dispenser dispenses a second pallet which is carried to the first build position. The second robot picks products from a second pick position and places them on the upper portion of the first pallet in order to complete the stack. Meanwhile, the first robot is picking and placing products on the lower portion of the second pallet.
