LABELER TYPE SETUP PROCEDURE
6-12
DUAL ACTION TAMP (DAT) SETUP (cont’d)
DAT SHOCK ABSORBERS AND FLOW CONTROLS
Both the Linear and Rotary Actuators have Shock Absorbers that need to be adjusted. The Swing Home
Shock has a Stop Collar installed. This Collar should be adjusted to provide 1/8” of shock travel. To
adjust the Shock so the Swing Arm stops in the right position, press the Manual Override on the Rotary
Actuator Valve and watch the movement of the Swing Arm. The Arm should hit the shock and stop
without bouncing. If it bounces too much, slow the Actuator down by adjusting the Flow Controls. The
Flow Controls are integrated into the Actuator and are located on each end of the longer cylinders. Turning
the screw in with a small screwdriver slows the Arm’s rotational speed and turning it out speeds the Arm
up. The Slide Shock Absorbers are larger and have longer strokes to ensure a smooth stop when moving
larger loads. The Shocks should be adjusted to ensure that there is at least 1/8” or more travel available
when the Slide Stop hits the body of the Slide. Do not allow the Shocks to bottom-out. To adjust the
Shocks, loosen the clamping screws on the Shock Mounts and screw the Shock in or out. When in
position, re-tighten the clamp to ensure the Shock stays in place. The Flow Controls for the Slide are
mounted on the Valve Bank. Screwing the knob in slows the speed of the Slide’s action while turning the
knob out speeds it up.
LABEL STATIC TEST
It’s important to know if the Applicator can consistently place labels in the same place on the product.
Without knowing this, you will not know whether label placement problems occurring on the line are due
to the Applicator or the product being labeled.
To test repeatability, configure the Applicator for Tamp Only Action. Position the Applicator with the
Tamp Assembly extended and the label pad approximately 1/8” away from the product. Jog several labels
onto the product. If the label stack is within the desired tolerances, go to the “Product Setup” section of
this insert. If not, go through the following suggestions to help find the problem.
1) Make sure that the labels are consistently stopping in the same place on the Label Pad. If this is OK go
to step 7; if not, go to step 2.
2) Check Label Stop. One label should be completely dispensed off the liner while the next label should
be 1/32” away from the Peel Edge Tip. If this varies more than 1/32” with each cycle, reset the Label
Sensor. If you still have the problem go to the Troubleshooting Section, page 10-1, of the 360a manual
and follow its suggestions. When this is corrected, go back and try the static test again. If this was OK,
go to step 3.
3) Make sure the Label Pad surface is clean. If clean, go to step 4. If not, clean and re-try the static test
again.
4) Make sure the vacuum is set correctly. If the label flutters while feeding across the pad, the vacuum is
too high. If the label falls off or moves after the label has left the liner, the vacuum is too low. If the
label feed looks smooth, go to the next step.
5) Work with the air pressure and the position of the Air Assist Tube until the label feeds more
consistently onto the Pad. Re-try the static test. If the results are still not good enough, go to step 6.
Otherwise go to 7.
6) Make sure you are working with good label stock. Try another roll of labels and see if you get the same
results.
7) Check the distance from the Label Pad to the product. If the distance is too large, the labels may float
too much. Try moving the Applicator so the Label Pad just clears the product (within 1/8”).
8) Is the Label Pad made for the label you’re using? Exposed holes on the Pad will reduce the available
vacuum used to hold the label in place and results will be uncertain.
