Abstract
An apparatus is provided for the transport of products in the course of a packaging process, where at least two pushers, pivotably mounted along a guide rod, are driven by a traction mechanism alternately back and forth in opposite directions along a product track. The pivotable mountings allow their respective pushers to swing between active and passive positions so that in the active position the pusher moves a product in one direction along the track, while a pusher in the passive position is pivoted away from the track while being driven in the opposite direction to return to a starting point. Upon reaching the starting point, the pusher in the passive position is pivoted back to the active position for moving the next product. The traction mechanism is preferably a toothed belt which is driven by a servomotor with a programmable speed profile, and the pushers are preferably connected to the traction mechanism by overload couplings. The pivoting movement of the pushers is preferably generated by curved tracks which are connected at their ends by shunt switches.
