Feeding and buffering workpieces in the tightest spaces
The SPU 2040 is an accumulating pallet recirculation system with automatic pallet return for cost-effective interlinking, feeding, buffering, positioning and separation of workpieces in the tightest of spaces. The system’s sturdiness and wide range of variants makes it suitable for virtually all automation and material flow applications.
The SPU 2040 allows for acyclic operation with automatic return of the pallets. The workpieces on the pallets are fed to the upper transport level by means of a flat top chain. After the workpieces are removed, the empty pallets are safely carried over the tail and then conveyed back suspended below the transport level. This means they are available again at the start of the production line to be loaded with new workpieces. Additional conveyor levels or lifting/lowering devices with complex control elements are not required. It also eliminates the need to load the pallets on the circulation system, whether manually or automatically.
The focus industries of this system include the automotive industry, machinery and plant engineering, consumer goods and electrical engineering.

The protective device guard at the tails minimises the risk of injury for the operator. A pendulum flap is triggered when touched and stops the entire system. A cover between the flat top chain and the frame is available on request. A protective device guard without a pendulum flap in profile design or as a sheet metal hood is also optionally available.
