11.11Pneumatic Speed Regulators

A)Upper unit ascent-descent speed regulators

B)Centering guides (infeed conveyor) speed regulators

C)Side belts opening-closing speed regulators

Side belts opening-closing speed regulators.

These are not common operations. They have to be made only when it has been necessary to work on the pneumatic cylinder.

To change the speed, do as follows:

1)Unscrew the locking nut 1

2)Turn the knob 2 clockwise to reduce the belts closing speed; counter-clockwise to increase the belts closing speed.

3)unscrew the locking nut 3

4)turn the knob 4 clockwise to reduce the belts opening speed, counter-clockwise to increase the belts opening speed.

Centering guides opening-closing speed regulators

These are not common operations. They have to be made only when it has been necessary to work on the pneumatic cylinder.

To change the speed, do as follows:

1)unscrew the locking nut 1

2)turn the knob 2 clockwise to reduce opening speed; counter-clockwise to increase opening speed.

3)unscrew the locking nut 3

4)turn the knob 4 clockwise to reduce closing speed, counter-clockwise to increase closing speed.
