Lifting and lowering conveyor for moving roller conveyor from lower position to upper position in conveyor belt for moving carriers for car body panel, comprises hoisting platforms engaged with roller bolts in groove roller in driven manner

摘要

The lifting and lowering conveyor comprises hoisting platforms (6) engaged with roller bolts (7,8) in a groove roller (3,4) in a driven manner. The groove rollers are driven synchronously by a motor (5) by Cardon shafts. The conveyor has a speed sensor, which measures the rotating position of one or multiple rollers. An intermediate shifting controller (16) is provided, which evaluates data of the speed sensor and disconnects the motor in the lifting position through a command by a superordinated controller (17) with additional information from upper and lower initiator designed as sensor.
