Problem
:
Case releases, all flaps drop, during folding or packing cycle.
•
Check that width adjustment is correct. If it is too wide, the wheeled “body switch” that
contacts the side of the case will reset and cause the machine to return to the start position.
•
Shaking the box to level the contents can cause the body switch to reset.
•
Check that the body switch is correctly adjusted and secured in the frame for proper box
contact and that the contact wheel is firmly attached.
Problem
:
Minor flaps fail to fold fully and return to home position, then may try to fold again.
•
Check that the actuator arms attached to the floor switches (mounted on floor plates) are not
out of position or loose. Both of them should be in a position to be pushed down fully by the
bottom flaps of the open box.
Problem:
Major flaps have difficulty folding and cause inner edges of minor flaps to be folded
over.
•
Check that the air pressure is adequate and that the air pressure does not drop during the
cycle.
•
Check that the flow controls on the small major flap opening cylinders are set so that they
will momentarily open the major flaps wider and allow the minor flaps to clear the inside of
the major flaps before releasing.
Problem:
Back or front case collapses inward during minor flap folding.
•
Be sure that the case width setting does not hold the box too tightly.
•
Check the air pressure and volume.
•
Check that the scoring on the box is adequate and promotes folding.
•
Check that the flow controls on the minor flap folding cylinders are set for a fast enough
speed of the minor flap folders. Excessive speed, however, can cause damage of the folder
arms.
Problem
:
Packed case fails to transfer smoothly from packing station into case sealer.
•
Check the height of the rollers at the outfeed end of the packing station and that the box
clears the machine frame.
•
Check that the machines are aligned accurately, i.e. that the belt surfaces line up with the
insides of the packing station when in the vertical position. Use a long straight-edge to check
the alignment.
