Abstract
A tote accumulator includes stack retaining latches that are configured to be acted on by a cam and follower mechanism and additionally by a holding mechanism. The cam and follower mechanism is configured to act on the stack retaining latches when the stack of totes is moved vertically by a lifting member, to move the stack retaining latches into an active dwell wherein the stack retaining latches are engaged with the stack of totes. The holding mechanism is configured to be activated to extend the active dwell after the cam and follower mechanism ceases to act on the stack retaining latches. The active dwell is extended even further by a mechanical interlocking feature between the latches and the totes. In various implementations, the design of the cam and follower arrangement and the activation timing of the holding mechanism may be adapted to execute a stacking or an unstacking operation.
