Method of forming U-shaped insert and inserting about goods in container

摘要

End of arm tool (10) is used to load goods A and B in two layers in a packing container (8), with a packing insert positioned between the layers. The tool (10) also grasps a packing insert in the form of a flat sheet, bends the ends of the packing sheet downwardly to form an inverted U shape, and then inserts the packing insert in a straddling relationship about the lower layer of goods A, to protect the lower layer of goods from the weight applied by the upper layer of goods B.

1. A method of packing an open top container having a bottom wall and side walls with a plurality of goods, comprising
retrieving with vacuum cups of an end of arm tool a first plurality of goods in a pattern that fits the size of the bottom wall of said open top container and placing the goods with the vacuum cups between the side walls and on the bottom wall of the open top container, grasping with the vacuum cups a central portion of a flat sheet and bending end portions of the flat sheet to form the flat sheet into an inverted U-shaped insert that includes a central panel sized to cover the first plurality of goods in the open top container and opposed side panels sized to fit between the first plurality of goods and the side walls of the container, inserting with the vacuum cups the inverted U-shaped insert downwardly into the open top container with the opposed side panels of the inverted U-shaped insert extending between the first plurality of goods and the opposed side walls of the open top container, withdrawing the vacuum cups from the open top container and moving the vacuum cups to pick a second plurality of goods, and as the vacuum cups withdraw from the open top container pushing the central panel of the inverted U-shaped insert away from the vacuum cups, and retrieving with the vacuum cups a second plurality of goods in a pattern that fits the size of the central panel of the U-shaped insert and placing the second plurality of goods with the vacuum cups between the side walls of the container and on the central panel of the of the inverted U-shaped insert.
