ABSTRACT:
An apparatus for automatically adjusting the distance between two support members for carrying workpieces of different dimensions. The support members are mounted on guides that are fitted to pallets that travel on conveyor transport systems for automatic production/assembly lines. In one embodiment the support members have a locking device that frictionally secure the support members in place on the pallet and can be unlocked for movement along the guide. A positioning unit engages the pallet so that the locking device is unlocked and the support members are engaged and translated to the desired locations under the control of a drive. In a second embodiment the support members are translated along and under the control of a threaded bar. A positioning unit engages the pallet to activate the threaded bar by rotating it to translate the support members to the desired locations. The support members are independently translated using one threaded bar and the drive for each support member. The location of the support members may be determined before adjusting the support members for the dimensions of the workpiece to be supported. Devices for bringing a pallet and the positioning unit together to make the adjustment are provided.
