The Gillette Company currently uses index-dwell conveyors to produce razor blades for final assembly. The objective of this project was to develop a continuous motion mechanism to offload and stack finished blades into a stationary magazine at 1500 parts per minute. To complete this objective, a detailed CAD model was developed to allow complete mechanism design, analysis, and proof of concept of all functional elements critical to the blade offload process. The final offlaod mechanism consists of a multi-cam driven inline linear reciprocating tool with both horizontal and vertical travel. The complete stacking operation consists of linear travel of the blade along a contoured track followed in conjunction with a magazine upstack operation, performed by a barrel cam and two radial cams, respectively.
