A device for stepwise and positionally displacing of objects.

摘要

Device for the stepwise and positionedly displacement of objects (3) - which are in friction contact with a continuously moving conveyor - along a processing or treatment station. The positioning means are formed by at least one worm (7) that is rotatably mounted about an axis (8) parallel to the travelling direction and projects with its helical rib (10) into the conveying path of the objects (3) and fits between two successive windings of the rib (10), the upstream flank (10a) of the rib (10) being provided - at angularly (pitch angle alpha ) spaced locations along the helix - with flattenings (11) that lie in planes that are perpendicular to the axis (8), said worm (7) being mounted to be intermittently driven - in angular steps alpha - in a direction opposite to the winding direction of the rib (10), in such a way, that the projecting part of the object will come to a standstill against a flank flattening (11) at the end of each angular step of the worm (7). <IMAGE>
