Bottom sheet dispenser for load forming machinery

摘要

A bottom sheet storage and feeder apparatus (1) for use with one or more load forming or stacking machines for the purpose of providing one or more bottom sheets (2) for protecting the load. The apparatus chooses a bottom sheet (2) stored in one of a plurality of vertically stacked bins (6) and sequentially moves one or more of the individual bottom sheets longitudinally to a destination location (3) in a plurality of lay down patterns (4). The machine is constructed with a frame (5) which supports a plurality of vertically spaced storage bins (6). A lifting assembly (11), transported by a transfer assembly, includes at least one laterally positioned vacuum member (12) which engages and lifts an individual bottom sheet (2) from one of the storage bins (6) and delivers the selected bottom sheet (2) to a destination location (3) in a selected lay down position. Several lay down patterns may be made by subsequent cycles of the lift and transfer assembly from the storage bins (6) to the destination location (3).
