Abstract
An improved case setup station in/for a case erector is provided. The station includes a transfer assembly, an actuatable a case blank clamp, and a case blank expander. The transfer assembly secures a vertically oriented case blank from a supply of vertically oriented case blanks and delivers same to the case blank clamp while maintaining a vertical orientation for the case blank. The clamp is downstream from the supply of vertically oriented case blanks and extends in a process flow direction for holding a delivered case blank, the clamp is characterized by first upstream and second down stream vacuum cup pairs, a first surface of a delivered case blank engaged by the vacuum cup pairs. The expander is adjacent the clamp, and is actuatable so as to travel towards and away from a held case blank of the clamp. The expander is securable to a second surface of the delivered case blank held by the clamp during a first actuation motion, the second surface of the delivered case blank held by the clamp pulled away from the first surface of the delivered case blank held by the clamp during a second actuation motion.
