Abstract

Two work stations for a continuous nonsynchronous automated line are shown. In Fig. 1, the frame to be registered and worked upon is held in a vertical orientation. In Fig. 2, the frame is held in a horizontal orientation. In each case, the frame is stopped at the work station, lifted off a continuously driving conveyor belt, and clamped in a registered position. Robotics for working on the frame after it is clamped in position are not shown. In Fig. 1, frame 10, shown in dashed lines, is fed into the station on conveyor belt 12. The front of the frame strikes stop 14 which is extended into the path of the frame by pneumatic cylinder 16. When the frame breaks the light beam at sensor 18, the clamping mechanism is actuated. The clamping mechanism begins by cylinders 20 raising lift 22.

Continuous Nonsynchronous Automated Assembly Line

Two work stations for a continuous nonsynchronous automated line are shown. In Fig. 1, the frame to be registered and worked upon is held in a vertical orientation. In Fig. 2, the frame is held in a horizontal orientation. In each case, the frame is stopped at the work station, lifted off a continuously driving conveyor belt, and clamped in a registered position. Robotics for working on the frame after it is clamped in position are not shown. In Fig. 1, frame 10, shown in dashed lines, is fed into the station on conveyor belt 12. The front of the frame strikes stop 14 which is extended into the path of the frame by pneumatic cylinder 16. When the frame breaks the light beam at sensor 18, the clamping mechanism is actuated. The clamping mechanism begins by cylinders 20 raising lift 22. Lift 22 carries three reference pins 23 that contact reference surfaces on frame 10 when lift 22 rises. Frame 10 lifts about 60 mm above conveyor belt 12 and contacts three reference pins 24 at the top of the work station. After frame 10 has been lifted by lift 22, clamping fingers 28 and 29 pull frame 10 horizontally until it is clamped against reference pins 26. Lower clamping finger 28 is moved by pneumatic cylinder 30, while upper clamping finger 29 is moved by pneumatic cylinder 32. With frame 10 lifted off the belt and clamped in position, a robot can install components in the frame as belt 12 continues to move. After work on frame 10 is completed, clamping fingers 28...
