Note: The case sealer can accommodate most boxes within the size range listed above.

However, if the box length (in direction of seal) to box height ratio is 0.6 or less, test-run

several boxes to ensure proper machine performance.

DETERMINE THE BOX LIMITATIONS BY COMPLETING THIS FORMULA:

BOX LENGTH IN DIRECTION OF SEAL = SHOULD BE GREATER THAN 0.6 BOX HEIGHT

Any box ratio approaching this limitation should be test run to ensure performance. Test-run any box ratio approaching this limitation to ensure performance.

Using a 10mm combination wrench, remove the fasteners that secure the case sealer legs to pallet at each leg (as shown in Figure 6-4).

Fasteners

Figure 6-4

Remove the leg height adjustment cap screws and replace with the cap screws from the tool kit. Loosen both cap screws. Remove and replace them one at a time to keep the inner threaded plate in position.

Using a 3mm hex wrench, remove the Height Adjustment Handle and reinstall it with the handle pointing upward as shown in Figure 6-5.

Figure 6-2

After cutting out or removing the staples, lift the shipping box in order to clear the machine (two persons required).

Figure 6-3

Transport the machine with a fork-lift truck to the operating position. Lift the pallet at the point indicated in Figure 6-3 (weight of machine + pallet = see Section 4).

(see Section 4).

7.2 Space Requirements for Machine Operation and Maintenance Work

Minimum distance from wall (Figure 7-1):

A = 1.0m. (39.4 inches) B = 0.7m. (27.6 inches) Minimum height = 2.7m. (106.3 inches)

WARNING

• To reduce the risk associated with

muscle strain:

− Use the appropriate rigging and material

handling equipment when lifting or repositioning this equipment.

− Use proper body mechanics when

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

WARNING

• To reduce the risk associated with

mechanical and electrical hazards:

− Read, understand, and follow all safety and

operating instructions before operating or servicing the case sealer.

7.3 Tool Kit Supplied with the Machine

A tool kit containing some tools are supplied with the machine. These tools should be adequate to set-up the machine, however, other tools supplied by the customer will be required for machine maintenance.

1 - Lift the machine with belts or ropes paying attention to place the belts in the points (Figure 7-2).

To set the machine bed height, do the following:

2 - Adjust machine bed height. The case sealer is equipped with four adjustable legs that are located at the corners of the machine frame.

The legs can be adjusted to obtain different machine bed heights (Figure 7-3). Also refer to the "Speciﬁ cations" section.

3 - Lock the screws.

4 - Repeat the operation for all legs. (It is not necessary to ﬁ x or anchor the machine to the ﬂ oor).

8-THEORY OF OPERATION

8.1 Description of the Working Cycle

After having closed the top ﬂ aps of the carton, the operator pushes it under the top infeed end in order to avoid the opening of the top ﬂ aps. Further pushing causes the two top and bottom belts to drive the box through the taping heads which automatically seal the top and bottom seams. The carton is then expelled on the exit conveyor.

8.2 Definition of Running Mode

The case sealer a20 has only one (automatic) operating mode with:

- The EMERGENCY STOP BUTTON unlocked (Figure 8-1)

- The main rotary switch start switch “ON” (Figure 8-2)

Figure 8-1

8.3.1 Normal Stop Procedure

When the main switch is turned OFF, the machine stops immediately at any point of the working cycle. The same thing happens in case of electrical failure or when the machine is disconnected from the mains.

8.3.2 Emergency Stop

The LATCHING EMERGENCY STOP BUTTON is located on the top center of the machine (This part is not produced by the machine manufacturer Figure 8-1).
