Transport installation for a production line having parallel-arranged processing stations
First Claim
1. In a production line for the manufacture of electric structural parts such as rotors and stators, the production line including a conveyor belt and a plurality of processing stations disposed along the conveyor belt, workpiece carriers mounted on and transported by the conveyor belt, each carrier comprising workpiece receiver means, the improvement comprising lifting means at each processing station for lifting at least one carrier from the conveyor belt into a holding position for further handling while leaving said conveyor belt unobstructed so that subsequent carriers are conveyed on said belt below the lifted carrier, gripping means for selectively removing and inserting workpieces into and from said workpiece receiver means of the lifted carrier, said lifting means arranged to lower the lifted carrier back onto said conveyor belt, and movable stop means adjacent said conveyor belt upstream of said lifting means to stop a subsequent carrier as said lifted carrier is being lowered back onto said conveyor belt, said lifting means being arranged to permit a lifted carrier to be moved horizontally, guided by rails, while seated on said lifting means in a lifted position.

Abstract
A production line for the manufacture of electric parts includes a conveyor belt and a plurality of parallel-arranged processing stations disposed along the belt. Workpiece carriers are transported by the belt. Each processing station includes a lifting mechanism which lifts at least one carrier from the belt for further handling, while leaving the belt unobstructed so that subsequent carriers can be conveyed beneath the lifted carrier. A gripper inserts workpieces onto the raised carrier and/or removes workpieces from the raised carrier. Movable stops are positioned upstream of the lifting mechanism to stop a subsequent carrier as the lifted carrier is lowered back onto the belt.
