ST-700 model of the SIGMA Transfer System – handles curves like a racecar
on an alpine pass road...

The extraordinary flexibility of SIGMA transfer technology comes to the fore in an ST-700 transfer unit delivered to a major German customer (supplier to the auto industry).

The workpiece carriers (WPCs) are transported on sliding shoes on a plastic chain running along the center. The chain can be diverted to 45º/90º/180º in the horizontal plane with minimal effort. As a result, you can create the most compact manufacturing cells, adapted ideally to existing structures or locations with limited space. This example shows how little space is needed to accommodate a manufacturing cell with a total of six manual work stations (MWSs). This transfer system requires only one drive module, yielding economic advantages in terms of energy consumption as well as control and maintenance work. A pneumatic chain tensioner ensures optimum interlocking and tensile force for the transport chain. Made of POM white (Ertalyte), the transport chain can be used in ambient temperatures ranging from – 20° C to + 80° C. The SIGMA transfer unit is especially suited to jobs involving the use of oil and water emulsions. For instance, it is becoming increasingly significant in its capacity as a buffer system and in the logistical linkage of compact manufacturing cells in mechanical manufacturing. The workpiece carriers have a useable surface area of 150 by 150 mm and a maximum loading capacity of 8 kg. They are adapted to whatever the possible layouts happen to be. With their hexagonal shape which is well-suited for curves, even the diversions can be fully used as buffer space.
