2-6-3. Dynamic Tests
The following procedures check the actual operation
of the 800rf Case Sealer. The following conditions
must be observed.
•Electrical power and compressed air are available
and turned on.
•The four safety doors are in their closed posi-
tions.
•Cases should have:
−the bottoms folded closed
−a minimum weight to hold the case on the
conveyor bed with the bottom flaps flat
−the front and rear flaps inside the side flaps
1. Apply air pressure and electrical power and press
the RESET and the START buttons on the
Electrical Control Panel.
2. If applicable, run the longest box (19 inches to 24
inches) through the case sealer. Check the
following sequence of events.
a. The box feeds from the infeed conveyor
rollers. The box is centered by the box
centering rails and the box stop gate moves
up.
b. The box is released and moves to the side
belts.
c. The side belts move inward and hold the box,
driving it toward the fork.
d. The box arrives at the fork and the side belts
stop driving the box.
e. The head lowers to the box, stopping at the
top of the box without distorting it.
f. The side belts restart.
g. Just before the sides of the box are folded
down, the rear flap of the box is folded down
into place.
ü Note
The timing of step g will vary depending on the
length of the box.
h. The sides of the box are folded down.
i. The top flap compression rollers touch the
sides of the top of the box without causing
the side flaps to overlap.
j. C-clips of tape are applied to both the top and
bottom center seams of the box.
k. The box exits the case sealer.
l. The head rises to its upper position, the side
belts return to their outer position, the fork
rises to its normal position, and the box stop
gate lowers to allow the next box to be fed
into the machine.
ü Note
If any of the steps outlined above do not occur
correctly, refer to the appropriate adjustment in the
Adjustments section of this manual.
3. If applicable, repeat the procedure outlined in
step 2 using the shortest box (8 inches to 13
inches).
4. If applicable, repeat the procedure outlined in
step 2 using a box between 12 and 19 inches.
5. Now that a representative sample of boxes has
been checked and appropriate adjustments have
been made, flood the infeed line with a random
array of boxes and check for consistent opera-
tion of the case sealer.
