Sepro: 23 robots on display


After many years in Hall 10 at the Dusseldorf fairgrounds, Sepro is moving to Hall 12 in order to gain more floor space. The 255 m2 of booth space will be filled with 23 robots for a wide range of applications and operating parameters. For instance:

Two 6-axis articulated-arm units will be shown operating together with three 5-axis Cartesian robots in an entertaining automation ballet. Developed by Sepro Robotique in partnership with Stäubli Robotics, these two robot families are aimed at injection-moulding applications requiring complex part manipulation.

The vertical injection unit on a bi-material injection-moulding machine might interfere with movement of a standard beam robot, but the Sepro Multi-Inject 20 robot, which is being shown for the first time at K 2013, is different. This specially designed unit will be operating on a 210t Sumitomo Demag machine with a two-position rotating mould for making ice scrapers with soft-touch gripping surfaces. In operation, the robot picks a decorative label from a feeder and places it on the moulded scraper body before the gripping material is over-moulded. Then it removes the finished product to a conveyor as the cycle repeats.

A 60t Arburg injection-moulding machine will be operating with an S5-15 robot, the smallest model in Sepro’s line of three-axis servo-driven units for applications requiring multi-axis, multi-function parts manipulation. The robot will be presented in an axial configuration so that the horizontal beam runs parallel to the injection unit. This cell will produce a toy car with wheels that move on metal axles. A cycle begins as the robot picks metal axles form a feeder and places them in the tool. The wheels are moulded on the axles as the body of the car is moulded in another cavity. After moulding, the robot removes all components from the mould and places inserts for the next cycle before moving the finished parts outside the moulding area. Wheels and axles are placed in a fixture at the end of the moulding machine and the body of the car is press-fit onto them. Finally the finished car is placed on a conveyor and the cycle repeats.
