AST-Series

The Hirata palletizing systems of the AST-series are compact tray changers, which can fed tray stacks, seperate trays, load and unload trays by robots and restack them in a very confined space. The exact positioning and the quick change of the trays as well as the large storage capacity of the palletizers meet the requirements of an automated production line. Typical applications of these tray changing systems are the assembly of small parts and the palletizing of parts on plastic injection molding and tooling machines.

In combination with Hirata SCARA or linear axis robots, the palletizers ensure a fast and economic loading and unloading of trays as well as a fast and precise assembly. The AST-palletizers process tray sizes from 400 mm x 300 mm to 800 mm x 600 mm up to a weight of 100 kg. The number of variants and the combination of several palletizers allow an optimal adaptation to almost every production process. The compact design and the freely selectable tray flow direction of the palletizers offer a space-saving installation with large storage capacity. In connection with ground conveyors they can be extended to fully automatic systems.

The basic unit is equipped with a storage capacity of one filled and one empty stack. If required, additional buffer belt segments can be connected to the basic unit. Depending on the weight of the filled stacks, an integrated docking station for transport trolleys is available for the basic unit, where the stack is automatically transferred to the transport trolley. In addition, direct palletizing onto commercial floor rollers is possible. If the empty stack is too heavy to be loaded manually or if it is to be delivered to the palletizer by ground conveyor, the empty stack can be brought to the level of the loader with another lift module between docking station and base module.

Depending on the requirements, for example it is also possible to link several AST-modules together. This can be done in two different ways. The first possibility is to have the tray changing systems operated by a SCARA robot. The other option is, that the empty pallet stacks are not removed, but transported further together by cross transport. If required, the tray changing systems can also be supported by a system for image processing.
