STIMA automatic loading and unloading device for raw material and processed sheets for 2D laser machines Compat Server (compact tower) Manufacturer description: The Platino Fiber laser cutting machine is a result of the perfect balance of innovation and experience. This product combines state-of-the-art efficient and ecological fiber laser technology with the proven reliability and flexibility of the Platino platform. The Platino Fiber can be used to cut a variety of materials. Fiber lasers are more effective than other laser sources at cutting highly reflective materials (e.g. aluminum alloys, copper, brass). The Platino Fiber cuts various thicknesses, up to 20 mm of mild steel, with efficiency and quality. The productivity increases are particularly noticeable with thin to medium-sized sheets. Compact servers: is a loading and unloading device for handling blanks and processed sheets. Compact Server consists of two storage units - one for blanks and one for processed sheets. All components of the Compact Server are located above the automatic pallet changer and therefore require no additional floor space. The advantages of these solutions are: reliability, compactness and easy management of loading/unloading operations. The newest product from SPR Italy is a highly sophisticated automation system that combines many innovative solutions that are subject to SPR patents. The system is capable of unmanned operation and provides storage, loading and unloading within the smallest footprint possible. The tower is built above the shuttle table and the loading and unloading is done with the elevator that can be installed on either side of the tower. Simple operation and state of the art PLC contribute to a friendly integration and provide real productivity gain. The system is so compact that it became the top selling automation product, with many hundred of them sold world wide in just few years since it was launched. Compact Tower CT 1530 is capable to store a maximum of 54 ton of raw sheets dim. 1500x3000mm stacked in18 locations, with 80mm each stack, and to load raw sheets onto the machine table and unload processed sheets thereafter. For this example we will use a 18 pallet tower such as we already installed in Melbourne this year. The scope of the work includes the software implementation, the tests of the units at SPR factory, shipment, documentation and supervision during installation, start-up and commissioning Concrete foundation to the engineering specifications, civil works, mains electrical supply, permits and the base plates must be supplied by Customer. Major components The Compact Tower is composed with following main units: - tower to store the stack of sheet - elevator to move the pallet on which the stack of sheet is laid - table with fixed pins where the operator load the stack of sheet - gripper with suction cups - light barriers - electric cabinet with control panel - set of safety fences General features: Sheet format max. 3.100×1.570mm Max weight 3.000Kg per stack Max height stack
