If the optional auto-retract sensor is installed (OTS screens,
page 26
),
this screen will be visible for adjustments. The auto-retract sensor will
detect the product surface before contact. This allows the lightest
touch of the label to the product, which can accomplish nearly the
same effect as a tamp/blow on many products and have the benefit of
positive contact to ensure label transfer onto the product surface. Since
the speed of the cylinder can vary, based on the pressure and flow
control settings, the auto-retract employs an adjustable delay. This
delay is started when the sensor first “sees” the product, and allows
additional time to contact the product. If the delay is set too short, the
tamp pad may never hit the product. If set too long, it will hit the
product too hard. If it is set to zero, the auto-retract will be disabled,
and the system will solely use the tamp duration timer to cause retract.
If the optional Label Present sensor is installed (OTS screens,
page 26
), this screen will be visible. The Repeat screen allows a safe
guard to be set to prevent multiple labels to be fed for a single tamp,
and/or prevent multiple application attempts of the same label. The
repeat print function can set a limit to the number of labels fed to the
tamp pad for a single application cycle. Likewise, the repeat tamp
function can prevent applying the wrong label to the next product. In
applications where each label contains unique information for the
product this setting can stop the system from continuing if the label
returns with the tamp pad after an application cycle.
In this screen, the trigger for printing the next label is selected. For
batch applications requiring the fastest throughput, the choice of Tamp
Return works best. This will generate a label each time the tamp pad
returns home. A choice of Product Sensor 1 allows print to follow the
trigger of the product sensor. This requires the product detector to be
placed far enough away from the system to allow for the label printing
to finish in time for application. This works well for applications where
each label is unique. A final choice of Product Sensor 2 allows printing
to start on a separate trigger than the application delay sensor. Again,
this is good for unique label format or varying information, with the
added benefit of better control of timing, and label placement.
To make recognition of the current job easier, an 8 character name can
be assigned to the job. This is accomplished via the Job Name screen.
The name can be a combination of numbers, letters, and some special
characters.
