Abstract

In a nonsynchronous automated assembly line, a buffer station is used for buffer storage of workpieces on the assembly line. The workpieces 2 enter the buffer station (Fig. 1) and are lifted vertically from conveyor belts 4 by side rails 14. When storing workpieces, side rails 14 move upward to lift the workpieces off conveyor 4. When supplying workpieces, side rails 14 move downward to lower workpieces 2 back onto conveyor 4. In Figs. 2 and 3 of the buffer station, there is shown an entrance gate 10 and an exit gate 12. Each of these gates is actuated by a pneumatic piston. Inside the buffer station (Fig. 1), there are five pairs of parallel rails 14. Each pair of rails can accommodate three workpieces that enter the buffer.

Vertical Buffer in an Automated Assembly Line

In a nonsynchronous automated assembly line, a buffer station is used for buffer storage of workpieces on the assembly line. The workpieces 2 enter the buffer station (Fig. 1) and are lifted vertically from conveyor belts 4 by side rails
14. When storing workpieces, side rails 14 move upward to lift the workpieces off conveyor 4. When supplying workpieces, side rails 14 move downward to lower workpieces 2 back onto conveyor 4. In Figs. 2 and 3 of the buffer station, there is shown an entrance gate 10 and an exit gate 12. Each of these gates is actuated by a pneumatic piston. Inside the buffer station (Fig. 1), there are five pairs of parallel rails 14. Each pair of rails can accommodate three workpieces that enter the buffer. When a pair of rails is full, motor 16 is energized to move rails 14 upward, lifting three workpieces 2 up into the buffer. During the lifting operation, gate 10 moves down to block further workpieces from entering the buffer. When the buffer station is to release workpieces, gate 12 is opened and a pair of rails 14 carrying workpieces lowers the workpieces onto conveyor belt 4 at the bottom of the buffer. When all the workpieces from that pair of rails have exited the buffer, motor 16 is energized to lower the next pair of rails containing workpieces down to the conveyor. When buffer storage of workpieces is not necessary, both gates 10 and 12 are up to allow workpieces to pass straight through...
