An innovative robotic island
Among the machines produced in the DMC plant in Grugliasco stands out a robotized island equipped with SMC components, characterized by a control transmission system realized through wi-fi, a decidedly avant-garde innovation for the sector. Intended for a Turkish customer, it is a jewel in terms of innovation. "It is an automatic machine for the assembly and testing of a car's rear backrest locking system. It features manual loading stations with presence controls via cameras while all the assembly stations are automatic. There is also a robot for the 'transfer' from a first table to the testing table. Parts are marked and values stored on a PC for traceability. On this machine we decided to use the wireless fieldbus system that allows us to have the I/Os on board the table without the use of the classic air-electric joint, which is subject to wear and tear, is not easy to maintain and requires a dedicated electrical cabinet that involves additional costs," explains Carmelo Todaro, Technical Office Manager. The heart of the machine consists of a series of electrical connections that are in contact via wi-fi with the central detector, which is able to manage them without contact. From phase to phase the table rotates and consequently all the groups rotate while the central pin remains fixed: every single element is therefore managed in wi-fi through SMC's innovative EX600-W.
Effective solutions
"Many of our machines, including this robotic island, are made with rotary tables with different positions that transfer groups, subgroups or components from one workstation to another.
One of the problems is the need to maintain control during movement: when moving, the table should carry electrical wires and controls. The jump on wi-fi that SMC proposed to us was really enlightening and allowed us to solve this problem effectively," Carmelo Todaro points out.
The technological collaboration with SMC is full of new and innovative solutions. "The SMC flow switch is useful for troubleshooting and monitoring the air consumption in the plant and thus evaluating energy savings. In another application, we used the SMC CKZT series, which allowed us to clamp the entire diameter of the tube so to work evenly.
We have as well installed SMC´s electric actuators, especially the LEY series, which allows us flexibility in positioning and setting up the machine both to us during the pointing phase and to the customer in the various phases of process and part modification" concludes Todaro.
Integration 4.0
A final note: all DMC machines are already designed to meet the requirements of Industry 4.0, an important plus for companies that are already oriented to a production management with sophisticated systems. "For us it is fundamental to rethink and develop new production, organizational and management processes”.
DMC Automation has long been working actively with SMC, the world leader in pneumatic automation. In the picture, the SMC flow switch mounted in a DMC machine.
