Reload Mechanism For Stapling Guns

This is an automatic reload mechanism which provides for a continuous supply of staples.

Staples in the form of staple bar 1 ride on slide bar 2 which is urged along by pusher channel 3 into the stapling gun 4. Air pressure in line 5, through solenoid valve 6 and air cylinder 7, maintains channel 3 and bar 1 pressed against gate 8 in gun 4. When driver 9 which is actuated by air cylinder 10 shaves off and drives a staple and returns to home position, channel 3 and bar 1 advance due to constant air pressure on the rod side of air cylinder 7 and a new staple is fed under driver 9.

When the staples in gun 4 are almost used, the extension of channel 3 closes switch 11 energizing relay coil 12. Relay 12 is maintained energized by closure of its contacts 13. Relay 12 also effects closure of contacts 14 to energize solenoid valve 6 causing the air pressure to reverse and move channel 3 away from bar 1 to the end of slide bar 2. Stacked staple bars 15 move down due to gravity causing the bottom bar to ride on slide bar 2. Channel 3 opens switch 17 at the same time deenergizing relay coil 12 and solenoid valve 6. Air pressure on the rod side of air cylinder 7 moves the channel 3 and a new bar 1 forward.

Air line 18 is the exhaust line and 19 indicates the power connections.
