ABSTRACT:
A box erector for erecting a box from a knock-down configuration into an open rectangular box is disclosed which includeds a frame (10) for an inventory section (20), a transfer section (22), a flap closure section (24), a taping section (26), and an exit section (28). A transfer arm (A) pivots to a pick-up position where a vacuum assembly (B) picks up a top box and pivots the top box to a box-opening position at approximately 79.degree. from the pick-up position. At the box-opening position, the box is rotated 45.degree. from its horizontal pick-up position, and first and second arms (78, 80) of vacuum assembly (B) open the box to a rectangular shape. Thereafter, the transfer arm moves the box to closure section (22). A drive belt (88) and drive pulleys (88a, 88b) rotate vacuum assembly (B) so that the box is vertically oriented when deposited at flap closure section (24). A pressure foot (92) extends into the box at the closure section and holds the box against the end flaps (29a) and side flaps (31a) as they are closed. The closed flaps are then moved across taping section (26) by horizontal movement of pressure foot (92). The flaps are taped closed, and the box is moved to exit section (28) where it is released upon demand from a product feed line.
