The GS family of palletizers automatically stacks cases on a pallet in a variety of patterns. A conveying
system will deliver cases to the machine’s infeed. An escapement or infeed belt will control the flow
of product into the machine and gap the cases to suit the machine’s internal functions.
A cushioned turning device rotates the cases, as needed, to suit the pattern requirements. Case
stops in the row forming area are used to generate voids. A pusher bar transfers the cases one row
at a time, from the row forming area to the apron.
When an entire layer of product is on the apron, the carriage raises to a height above the empty
pallet or the previous layer on the pallet. The apron advances over top of the pallet with its layer
of product. A stripper bar swings down behind the layer and the apron reverses its travel, depositing
the layer on the pallet or the partially built load. The carriage now lowers into position so that
the apron can receive the next layer of product.
The GS140 builds the load on a chain conveyor. When the load is complete, it is automatically
discharged from the load build cavity and an empty pallet is conveyed into position. A safety light
curtain protects the load discharge opening. Empty pallets are loaded by fork truck into and empty
pallet dispenser. The dispenser automatically separates one pallet from the bottom of the stack and
feeds it to the pallet pre-stage position.
