7-INSTALLATION AND Setup (continued)

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

7.16 Tape Loading/Threading

See Manual 2.

Note – If lower tape drum is mounted in alternate lower outboard position, remove taping head from machine bed by pulling straight up, insert threading needle in taping head and replace taping head. Install tape roll on drum (adhesive on tape leg up), thread tape under knurled roller on outboard mount, then attach tape to threading needle and pull tape through taping head with threading needle.

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

7.17 Theory of Operation

Box Centering Switch

Figure 7-19 – Box Centering Switch

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 7-20, causing the upper taping head to be raised by two air cylinders. 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 pinch 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 pinch 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 7-19,the lever is depressed causing the air cylinder powered centering guides to move inward, thereby centering the box.

CAUTION

•To reduce the risk associated with pinch and entanglement hazards:

−Keep hands, hair, loose clothing, and jewelry away from moving belts and taping heads
