  • 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.
    Type: Grant

  • Patent number: 7950896
    Abstract: A handling apparatus can be used to transfer objects from a first location to a second location along a defined path, without the need for a conveyor along the path. Instead, the handling apparatus can be moved along the path by a controllable transport device, such as a robot arm. The handling apparatus can comprise a plurality of unpowered rollers which are selectively rotated by way of a transfer assist mechanism during loading and/or unloading of the objects to be transferred. The transfer assist mechanism can comprise a separate component that can power the rollers directly or indirectly. The transfer assist mechanism can comprise a belt which imparts rotational force to the support rollers via contact in some embodiments, with the amount of force controlled by varying the relative inclination of the support rollers and the transfer assist mechanism.
