VACUUM CUP ADJUSTING INSTRUCTIONS:
A.
Although there is really no specific formula for setting the vacuum cup pattern on
your case, these few simple rules should be followed. The carton will open better
and stand less chance of collapsing, if the cups are positioned approximately ½”
from the case edge and ½” up and down from the top and bottom score lines.
B.
Unless the case is less than 8” wide, then you will have to raise the lower
two vacuum cups to approximately 1 ¼” above the bottom score line to avoid
interference with the case pusher assembly.
C.
Positioning the vacuum cups on the carton score line, is not best practice, but
in some cases it may be necessary.
CASE WIDTH ADJUSTMENT
Put a fully formed carton into the drive section at the discharge end. Loosen locking
lever and turn hand wheel until you have approximately 1/8” clearance on each side
of carton. Use the scale for approximate measurement.
BLANK HOPPER ASSEMBLY
A.
When loading different length knocked-down cartons into the magazine,
remember the long side guide rail will have to be adjusted. The short rail side
never moves, this is your fixed point.
B.
Adjustment to the case retainer bar and the brush will probably not be needed.
But if adjustment is desired, the round retainer rod right and brushes left, via the
adjustment slots. The rod and brushes slightly hold the cartons in an upright
position, as the vacuum cup assembly pulls the cartons from the magazine.
C.
The case bottom opening finger will need to be adjusted for every different case
size handled by the machine. This finger must be positioned in a manner as to slip
through the slots of the knocked-down case at the manufacturers joint and slightly
hold the inside rear panel as the vacuum cups pull the cases from the magazine.
This finger aids in forming the knocked-down case by breaking case at the scoring.
D.
Set finger so that it is approximately 3/8” from the front face of the case and ¼”
deep into the slot.
E.
At the front of the case magazine, is located an elevation adjustment. This hand
wheel, when turned clockwise, raises the bottom score line of the knocked-down
case, and counterclockwise, lowers the score line.
F.
The breaking point of the bottom leading and trailing case flaps, as the bottom
folder plates fold inner flaps upward, must remain the same on all cases as they
enter the forming section of the machine from the case magazine.
