New FMS Double Loader for Higher Payload Non-APC Machine Tools

Tampere, Finland – Fastems Group introduced its new load handler DMC-APC (Double Mast Crane-Automatic Pallet Changer) that can load machine tools directly as well as act as an automatic pallet changer. The load handler is the device on the FMS stacker crane that moves pallets between storage, machines, and the loading/material stations in a Fastems FMS. With the new multi-pallet loader, manufacturers do not need to purchase and integrate expensive APCs to their machine tools to configure an FMS (Flexible Manufacturing System) in their facilities.

The new DMC-APC can accommodate two pallets, which is controlled by the company's cell management software. It selects the next workpiece-loaded pallet from the storage system, transfers it to an open machine tool, then picks up the previously machined workpiece/pallet from that same machine tool, rotate 180-degrees, and places the new workpiece/pallet into the same machine tool, taking about 30-40 seconds. The non DMC-APC or classic stacker crane accommodates one pallet. The loader first removes the finished part/pallet from the machine tool, supplies it to the storage stacker, moves to pick up the next workpiece/pallet to be machined, and delivers it to the machine tool ready for machining, taking about 100-120 seconds.

The DMC-APC combines several remarkable advantages in one solution namely surrounding speed, machine tool utilization, and cost reduction as now that non-APC machine tools with higher payloads can be used in an FMS. Furthermore, it can accommodate higher weights up to 1,000kg as well as save floor space because machines without APCs have a smaller footprint generally.
