To restart machine, rotate emergency stop switch a quarter turn clockwise to releases switch latch. Restart machine by turning the switch to the "O" (Off) position then to "I" (On).

Figure 3-4—Air Regulator, Centering Guides

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.

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.

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.

Assembly

Operation (Continued)

For boxes which are fully packed with products that support the top flaps, the adjustment of this regulator is not critical since the boxes can support the pressure of the upper frame (drive belts) at a wide range of regulator settings. However, if under-filled or fragile boxes are sealed, this regulator can be used to set the upper frame pressure to a reduced level that is still adequate to positively convey the box and to prevent damage of boxes. The regulator setting can be locked by pushing the knob inward.

Note: A precision regulator is used to balance the top drive assembly. Due to the self relieving feature of this regulator a small amount of air will continually vent to the atmosphere. This is normal and amounts to approximately 3 liter/min

[0.1 SCFM ].

Indicates main air regulator pressure setting. Air regulator should be adjusted so gauge reads 5.2 bar gauge pressure [75 PSIG].

Pneumatic Valve, Drive Assembly Raising Switch (Figure 3-6)

The Pneumatic Valve Drive Assembly Raising Switch is used to hold the upper drive assembly to its fully raised position for tape threading and maintenance.

To raise the drive assembly, turn the switch to the right. To lower the drive assembly to its fully lowered position, turn the switch to the left.

WARNING

• To reduce the risk associated with muscle

strain:

− Use proper body mechanics when removing

or installing taping heads that are moderately heavy or may be considered awkward to lift.

Theory of Operation

Figure 3-7—Centering Guide Switch

CAUTION

• To reduce the risk associated with pinches

and entanglement hazards:

− Always feed boxes into the machine by

pushing only from the end of the box.

− Keep hands clear of the upper head support

assembly as boxes are transported through the machine.

• To reduce the risk associated with pinches

and impact hazards:

− Keep away from the pneumatically controlled

upper drive assembly and box centering guides when air and electric supplies are on.

The air supply powers movement of the centering guides and upper drive assembly to automatically adjust the case sealer to the box size being sealed as follows:

1. A box centering switch in the center of the infeed roller conveyor actuates movement of the centering guides. When the operator pushes a box onto the infeed conveyor, as shown in Figure 3-7, the lever is depressed causing the air cylinder powered centering guides to move inward, centering the box.

2. Once the box is centered by the guides, the operator pushes the box against the raising switch on the upper drive assembly, as shown in Figure 3-8, two air cylinders raise the upper drive assembly. The upper taping head will continue to rise above the box height so the operator can insert the box underneath the upper drive belts.

CAUTION

• To reduce the risk associated with pinches

and entanglement hazards:

− Keep hands clear of the upper head support

assembly as boxes are transported through the machine

Figure 3-8—Upper Drive Assembly Actuator Switch

Operation (Continued)

CAUTION

• To reduce the risk associated with pinches

and entanglement hazards:

− Keep hands, hair, loose clothing, and jewelry

away from moving belts and taping heads

3. Once the box is pushed under the upper taping head, the upper drive assembly actuator switch is releases to lower the upper drive assembly to descend onto the box top, as shown in Figure 3-9, allowing the drive belts to convey the box through the upper and lower taping heads for application of the tape seals.

4. As the box is conveyed through the machine, the centering guide switch is released causing the centering guides to return to their full open position, ready for insertion of the next box.

5. Once the box is conveyed from under the upper taping head, the upper drive assembly descends to its rest position, ready for insertion of the next box.

At this point it is recommended that the centering guides and upper drive assembly switches be manually actuated to better understand their functions. Depress the centering guide switch to close the guides. Release the switch to open the guides. Depress the upper drive assembly raising switch to raise the upper drive assembly. Release the upper drive assembly raising switch to lower the drive assembly.

Figure 3-9—Box Conveyed Through Machine

Machine or taping head adjustments are described in "Adjustments" Section I for machine or Section II for taping heads.

Note: Box drive motors are designed to run at

a temperature somewhat above ambient room temperature. A motor may feel hot to the touch during normal operation.

Box Sealing

1. Turn main air valve to (On).

Important: Before turning drive belts on, be sure no tools or other objects are on the conveyor bed.

2. Turn the switch on side of machine frame to start drive belts.

3. Feed boxes to machine. Always allow previous box to exit machine BEFORE feeding next box.

4. Turn air and electrical supplies "Off" when machine is not in use.

5. Reload and thread tape as necessary.

6. Be sure machine is cleaned and lubricated according to recommendations in "Maintenance" section of this manual.

Maintenance

The case sealer has been designed for long, trouble free service. The machine performs best when it receives routine maintenance and cleaning. Machine components that fail or wear excessively should be promptly repaired or replaced to prevent damage to other portions of the machine or to the product.

WARNING

• To reduce the risk associated with

mechanical and electrical hazards:

− Turn electrical and air supply off and

disconnect before performing any adjustments, maintenance, or servicing the machine or taping heads.

• To reduce the risk associated with impact

hazards:

− Always use appropriate supporting means

when working under the upper drive assembly.

Lubrication

The machine bearings, including the drive motor, are permanently lubricated and sealed and do not require additional lubricant.

Cleaning

Note – Never attempt to remove dirt from the machine by blowing it out with compressed air. This can cause the dirt to be blown inside the motor and onto sliding surfaces which may cause premature equipment wear. Never wash or subject equipment to conditions causing moisture condensation on components. Serious equipment damage could result.

Regular slotted containers produce a great deal of dust and paper chips when processed or handled in equipment. If this dust is allowed to buildup on machine components, it can cause component wear and overheating of drive motor. The dust buildup can best be removed from the machine by a shop vacuum. Depending on the number and type of boxes sealed in the case sealer, this cleaning should be done approximately once per month. If the boxes sealed are dirty, or if the environment in which the machine operates is dusty, cleaning on a more frequent basis may be necessary. Excessive dirt buildup that cannot be removed by vacuuming should be wiped off with a damp cloth.
