LABELER TYPE SETUP PROCEDURE
6-11
DUAL ACTION TAMP (DAT) SETUP (cont’d)
DAT GENERAL SETUP PROCEDURES
1) The Label Stop must be properly set for the Applicator to work correctly. Adjust the Label Stop Value
to position the label at or slightly back from the Peel Edge.
2) Tamp height should be adjusted so that the label feeds out in contact with the Label Pad. If the Pad is
too high, the label will not land consistently on the Pad. If the Label Pad is too low, the label will
dispense into the back of the Pad and jam. Most of this adjustment is done with the Peel Edge and is
discussed in the Tamp Applicator Setup Section of the Manual. It is important to adjust the Rotary
Actuator so the Label Pad is level with the Applicator.
The Rotary Actuator’s internal stops control
100% of where the swing arm stops – the shocks act as a “buffer” only! See the Rotary Actuator
Stop Adjustment Guidelines section.
3) Make sure the label is aligned with the Pad so there is no over-hang. To adjust this, move the liner web
in or out by adjusting the Guide Collars and Unwind Disks.
4) Position the Air Assist Tube with the hole(s) centered on the label and pointing approximately ¼”in
from the Label Pad Edge. The air pressure should be set at 20-30 PSI. Press “Jog” to dispense a label.
If the label doesn’t feed out against the Label Pad or the vacuum doesn’t capture it, increase the air
pressure. Continue until the vacuum captures the label.
Warning: There are other factors that can keep the label from staying on Label Pad. You may need more
vacuum, increased or decreased label dive, or the Air Assist Tube may need to be rotated.
5) Air pressure for the Tamp Slide and Rotary Actuator should start at 40 PSI, the Air Blast at 40-60 PSI,
and the Vacuum Pump at 20 PSI.
6) Air Blast Time is set through the Display and should be set long enough to apply a label firmly to the
product. Setting the time too high results in fewer labels/min a value to start at is 0.06 seconds. The Air
Blast Time applies to both the Swing and Tamp Sequences.
NOTE: To avoid injury, make sure the Applicator is offline for this adjustment!
ROTARY ACTUATOR STOP ADJUSTMENT GUIDELINES
1) Determine application – Reels-up, Overhead and Above etc. Keep in mind the gravity factor /
weight of the Pad and Manifold as this will be a factor of the supplied air pressure coming from
the Swing Valve Bank regulator – good starting pressure is 40 PSI.
2)
Adjust Airflow Needle Valves, which are located on the side of the longest “tube” of the Rotary
Actuator, with a flat blade screwdriver. Turning the screw CW – decreases the airflow. Turning
the screw CCW – increases the airflow. Typical flow control setting is ½ turn CCW from full
CW.
Note: proper settings = a smooth and controlled cycle!
3)
Proper set up for the 90-degree Swing Tamp. The Rotary Actuator Internal Stops control
100% of where the Swing Arm Stops – the Shocks act as a “buffer” only! With proper
amount of air pressure going to the Rotary Actuator, loosen the Retract Jam Nut, which is located
on the end of the longest Rotary Actuator Tube. Use a 3/16” Allen wrench and turn the stop set
screw CW. This action will move the Swing Tamp Arm away from the Tamp Home Shock. The
Tamp Home Shock should protrude from the Stop Coupling by 1/8” – 3/16”. If this is not the case
– make the necessary adjustments. Once this is set, turn the retract setscrew CCW until the Swing
Arm has come to rest against the Home Stop Shock Coupling. Tighten the Jam Nut.
4)
Set the Extend Rotary Stop as per above instructions. You will notice the Extend Shock does not
have a Stop Coupling. This Shock should be adjusted to allow for one half of its travel to be
compressed when the Swing Arm is extended.
