Stop Pins/Lift Tables/Clamp Bars
A. Stop Pins
1. Stop pins are pneumatic devices used to stop parts at each station.
2. The stop pins should raise and lower smoothly and quickly.
B. Lift Tables/Clamp Bars
1. The lift tables or clamp bars rise to hold the part in place when it is being
dispensed upon.
2. For optimum operation, the lift tables and/or clamp bars should raise and
lower at the same time and at the same rate.
C. Airflow Adjustment
1. Pneumatic controls regulate the amount of air pressure supplied to the lift
tables or clamp bars to control the speed of its up and down movement.
2. For optimum operation, the lift tables or clamp bars should raise and lower at
the same time and at the same rate.
3. The location of the pneumatic controls depends upon the device:
The controls for lift tables are located on the pneumatic hoses inside of
the dispensing area, to the rear of the lift tables.
The controls for clamp bars are located on the clamp bar pneumatic
cylinders at each conveyor station. One clamp bar is on the front
conveyor rail and one is on the rear rail.
4. Air pressure to stop pins is constant and does not need to be adjusted.
