Apparatus for loading packages into a bay is disclosed. The apparatus comprises at least one first section cup operable, when vacuum is supplied thereto, to support are side of a bag which extends generally vertically downwardly from the first suction cup, a feeding station operable to store bags in a generally horizontal position, a transfer arm, at least one transfer arm suction cup operable, when vacuum is supplied thereto, to support one side of a bag, and means for moving the transfer arm suction cup longitudinally of the transfer arm. The transfer arm is rotatable between a first position in which the transfer arm suction cup is aligned with a portion of a bag in the feeding station and a second position in which the transfer arm suction cup is generally aligned with the first suction cup. The transfer arm is operable to move the transfer arm suction cup into encasement with a bag in the feeding station, to pick up the bag when vacuum is supplied to the transfer arm suction cup, to rotate so that the bag extends generally vertically downwardly from the transfer arm suction cup to a position in which the transfer arm suction cup can be moved longitudinally of the arm between a first position in which the first suction cup and the transfer arm suction cup are in closely adjacent, opposed relationship, and a second position in which a bag supported by the first and transfer arm section cups is in an open position. The apparatus is also operable to load packages into the bag, to rotate the bag, into which packages have been dropped in a given direction so that its top moves away from the transfer arm, to move the rotated bag laterally to a transfer station, and to support the bag in its rotated position while it is moved to the transfer station. Finally, the apparatus is also operable, to rotate the bag after it reaches the transfer station, in a direction opposite to the given direction and to cause the rotated bag to continue rotating toward a horizontal position, and means for sealing the bag.
