Operation (Continued)

Pressure Regulator (Figure 3-3)

Regulates main air pressure to the machine to adjust pressure, pull knob up and turn; push down to lock setting.

Filter (Figure 3-3)

Removes dirt and moisture from plant air before it enters the case sealer pneumatic circuits. If water collects in bottom of bowl, unscrew the valve on the bottom of bowl to drain. When empty, retighten valve.

Emergency Stop Switch (Figure 3-2)

The machine electrical supply can be turned off by pressing the latching emergency stop switch. To restart machine, rotate emergency stop switch a quarter turn clockwise to re- leases switch latch. Restart machine by turning the switch to the "O" (Off) position then to "I" (On).

Upper Drive Assembly Actuator Switch (Figure 3-2)

This switch, when touched by the leading edge of a box , pneumatically raises the upper drive assembly to allow insertion of the box under the drive belts. As the box moves under the switch, releasing it, the upper drive assembly descends on the box and the drive belts convey the box through the machine. When switch is turned, the upper drive assembly rises. When the switch is released, the upper drive assembly descends to its rest position.

Centering Guide Switch (Figure 3-7) This pneumatic switch controls the box centering guides. When switch is activated by a box entering the case sealer, the centering guides close (centering the box), and released (after box passes over switch), the guides open.

Air Pressure Regulator, Centering Guide Force Adjustment (Figure 3-4)

This regulator is used to adjust centering guides according to weight of boxes. Pressure should be adequate to center boxes, but low enough to allow easy pushing of boxes under taping head.

To adjust the regulator setting, pull the knob outward, rotate the knob to the desired setting. Push the knob inward to lock it and prevent unintentional adjustment.

Air Pressure Regulator, Top Drive Assembly Force Adjustment (Figure 3-5)

Set nominally to control the "down" movement of top drive assembly and the pressure exerted against the box as shown in Figure 3-5. The regulator setting is changed as necessary for the boxes being sealed to provide adequate drive belt pressure against the box to positively convey the boxes through the machine. If the boxes stop or hesitate while being conveyed, decrease the regulator pressure. This increases the drive belt force on the box for more friction between the box and drive belts. Adjust the pressure setting as necessary to get continuous movement of boxes through the machine.
