Abstract

Conveyor systems for storage and movement of goods on pallets and slip sheets. The transfer structures enable slip sheet mounted loads to be transferred to a roller conveyor by providing structures that cooperate with wide platen forks of a lift truck. The structures provide roller contact between a portion of the underside of the slip sheet at all times. In other areas there is alternatively contact between a lift truck platen or additional rollers that cooperate in a manner making it possible to move the slip sheet mounted load from the lift truck to an adjacent conveyor system.

Claims

1. A conveyor transfer structure for use with loads resting on a slipsheet, the transfer structure comprising:

(a) fixed-position rollers for contact with the slip sheet and

(b) movable position rollers movable between first positions supporting portions of the slipsheet and second positions permitting lift truck platen contact with the portions of the slipsheet.

2. The conveyor transfer structure of claim 1, wherein the movable position rollers remain in contact with the slipsheet in the second positions.

3. The conveyor transfer structure of claim 1, wherein the movable position rollers move out of contact with the slipsheet in the second positions.
