Assembly «or processing machine with a tellexfOrmlgen workpiece carrier that can be continued step by step

Please refer to an assembly · or Processing machine with a rotating shaft that can be rotated around a vertical axis and can be held step-by-step through a holding shaft plate-shaped workpiece carrier and at least one geared to the Sohaltwelle and with her synohron running control shaft, ron the off over carts, work movements from around the Werketttokträgeraohee work units arranged around them are derived. *

In known ßohalttellermaeohinen of this type the star shafts and the holding shaft as well as the gearbox below the Sohaltteller in the Orundgestell the Machine housed on which the work units are arranged around the holding plate «BIe transfer the work movements of the work units happens guided upwards around the base frame around the outside,

According to the invention, the control shaft is bsw./dle control shafts in a horizontal plane above the workpiece carrier inside one on the base frame of the Maeohine against twisting housed held housing and carried out by a through the hollow work piece support spindle upwards The shaft is driven by a gear wheel at its lower end, protruding from the work spindle sur geared connection with the shift shaft carries o This means that the work units are around the outside of the base frame cumbersome transfer lever systems led upwards avoided. The control lanes are in a central area - above the workpiece carrier - the work units brought closer and are more favorable for the transmission of work movements at high speed. The transmission elements The work units arranged around the workpiece carrier on the base frame take effect from central point from above over the workpiece carrier and therefore do not need a very expensive flat in the ground plan the Maeohine. In this arrangement, they can no longer have a more disruptive effect on operation.
