How to Vibratory Feed Sticky Materials - Corks


An assembler wanted to automatically feed and orient synthetic corks at a feed rate of 200 parts per minute. These corks are very difficult to feed due to the sticky film that remains on the surface after the manufacturing process. Other challenges included noise levels and part orientation.

A conventional feed system would not meet the assembler’s performance requirements.



SPIROL Engineering recommended an 18” Series 2000 drive unit with a dual axis controller and a 24” fabricated stainless steel, dual discharge bowl. External bowl tooling in combination with an automatic shuttle mechanism was designed to orient the parts into a gravity track. As the corks reach the end wall of the shuttle, an air cylinder pushes them sideways into a gravity track effectively converting their orientation 90 degrees. A high level sensor ensures constant feed flow.

SPIROL’s Series 2000 high performance feed system achieved a feed rate of 220 parts per minute, exceeding the assembler’s feed rate requirement by 10%.
