Suction system plays a main role in transferring products or parts when manufacturing with its simple and stable grabbing properties. In order to maintain taking objects, the system should generate sucking force continuously, but usual suction mechanism is composed of multi-suction cup with one air compressor. Consequently, only a malfunction of suction cup can cause the damage to products. To prevent this, new suction mechanism was proposed using permanent magnet last year. The proposed mechanism activates each suction cup separately, therefore the grabbing stability was enhanced. But that also had demerits, namely, high load to actuator, bad influences to products caused by magnet, and low efficiency due to the sucking speed. So we propose more simple, stable and efficient method to give actuation to each cup using step motor not with magnets. With experiments, the development of lifting ability and stable suction performance are shown.
