Special Set-Up Procedure (Continued)
Figure 6-5 – Stop Bumpers
Box Height Range – (Refer to Figure 6-5)
The operating range of the upper drive assembly can be adjusted to minimize its movement to the range of box
heights being sealed. Therefore, the operating speed can be increased. The range is established by limiting the
lowest position of the drive assembly by positioning the stop bumpers at one of eight different levels on the side
columns.
The illustration in Figure 6-5 shows minimum box height with stop bumpers fastened through lower holes (A) at
different levels on the side columns. If bumpers are mounted with bolts through upper holes (B), the minimum
height of box in each position decreases by 20 mm [3/4 inch].
After establishing the minimum box height to be sealed, position the stop bumpers as follows:
1. Latch upper drive assembly in upper position, turn off air and electric.
2. Remove and relocate the stop bumper assembly to the desired position on both side columns. Be sure that
the stop bumpers are reassembled as shown and secure.
3. Turn on the air and electrical power to the case sealer. The upper taping head will now descend only part way
thus increasing operating speed.
In addition to the bumper supports, adjustable split collars are fitted onto the cylinder rods as shown in Figure 6-5.
These can be used to stop the down position of the upper assembly at any position. To adjust these collars,
position the smallest box to be sealed under the drive belts and stop the machine. Slide the collars on both
cylinders down to the cylinder cap and tighten. Upper drive assembly will now stop at this position.
•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
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
