Electronics Module

The electronics module, including the Operator Control Panel (OCP),
controls various data, inputs, outputs, and produces the precise sequence
of events, resulting in the application of a printed label onto a product. For
more information on the electronics module, refer “Setting Up the
Machine” on page 4-5.

Unwind Assembly

The unwind assembly removes labels from the label roll in a controlled
manner to suit the printer's label feed demand. It has a built-in braking
mechanism that progressively releases the label roll during "label feed",
and then reduces the speed of release when the label demand is reduced
or stopped. The unwind assembly is available for roll diameters of two
different sizes:

• 400 mm (16") for an outer wound label roll configuration

• 350 mm (13.75") for an inner wound label roll configuration

2-2 Introduction to the Printer Assembly

Rev AA

P3400 Operator Manual

The unwind assembly has a "twist lock" type of removable flange
assembly that eases the loading or replacing of label rolls.

Air Assist Assembly

The air assist assembly (Figure 2-2) contains a non-stick air assist tube and
an air supply tube. When the label passes from the peeler bar to the
application module, the air assist jet directs air onto the label, causing it to
deform. This process aids the placement of the label on to the application
module.

Rewind Assembly

The rewind assembly is used to rewind or take up the used label liner after
the printing and dispensing of a label. The rewind assembly is fitted with
a slipping clutch to accommodate the increase in diameter of the rewind
waste roll, as well as to accommodate different label printing speeds.

Low Label Sensor

The low label sensor detects a reduction in the diameter of the roll of labels
when it reaches a level of 5% of its total capacity. The sensor then signals
the LPA to send an alarm warning to the system about the low label
condition. The signal is interpreted as a "Low Label" message on the OCP
and/or an amber light glows on the optional lamp stack beacon.

Print Engine

The print engine (Figure 2-3) is mounted on the lower front of the
machine.

Secure the print engine hanger pin (Item 1 in Figure 2-3) into the print
engine, and then hang the print engine from the pin to ease the assembly
of the print engine fixing screws (Item 2).

Note: Not suitable for use within Datamax print engine.

The print engine comprises the following components:

2-4 Introduction to the Printer Assembly

Rev AA

P3400 Operator Manual

• Thermal printhead

• Electronic circuitry

• Ribbon drive and tensioning device

• Peeler bar

Thermal Printhead

The printhead is equipped with a series of very small, densely clustered
heating elements (dots) mounted on a ceramic substrate. When electrical
current is supplied to the dots, they get heated rapidly and melt the ink on
the ribbon. The ink deposits on the label, and quickly dries after the label
leaves the printhead.

Electronic Circuitry

The electronic circuitry comprises the following components:

• Microprocessors that manage the print engine and control printing

• Non-volatile memory that holds the print engine's operating system.
It is used for label creation and print engine configuration

• Volatile memory that holds the label data ready to be printed. Battery­backed memory for label storage is optional

• Internal power supply that converts the AC mains power into the DC
voltage, when required by the print engine

• The I/O interface that connects the print engine to the controlling
computer and the label applicator

Ribbon Drive and Tensioning Device

The ribbon drive consists of two spools on which the ribbon reels are
fitted. The ribbon unwind reel stores unused ribbon, and is free-spooling
under friction control. The ribbon rewind reel is driven by a motor, and is
used to take up the used ribbon, as it emerges from between the printhead
and the platen.

Peeler Bar

The peeler bar consists of a metal plate, and the label is routed over its
edge. As the label web moves over the peeler bar, the label is separated
from the label backing, and is positioned onto the label application
module.

Note: For specific information regarding your printer, refer the printer manual.

Rev AA Introduction to the Printer Assembly 2-5

P3400 Operator Manual

Label Web Path

The label web (Figure 2-4 on page 2-7) is routed into the print engine along
the label web path. The label web path comprises the following
components:

• Unwind reel - The shaft is tightened to ensure correct label web
tension, and to stop any run-out. A twist-lock collar is used to retain
the roll.

• Unwind dancer arm - The dancer arm is spring-loaded to absorb the
change in tension of the label web, during its movement through the
machine. It controls the unwind brake.

• Idler rollers - The idler rollers are free-spinning rollers that support
and guide the label web through the machine. The position of the
rollers is set for optimum feeding of the label web, both in and out of
the print engine, ensuring a high speed of label printing and
application.

• Label web guides - These spring-energized plastic rings are
positioned on the idler rollers to guide the label web into the print
engine. One is set on the inside edge of the label web, and the other on
the outside edge.

• Rewind reel - The spindle stores the label backing after the labels
have been printed and applied. It is motor-driven, and has a slipping
clutch to prevent run-on, and a dancer arm to even out variations in
the label rewind speeds. This keeps the used label web taut and secure
at all times.

Application Modules

The Videojet P3400 LPA is configured to accommodate seven different
types of application modules:

Note: Each tamp-based application module requires a tamp pad.

Tamp Pads

Tamp pads (Figure 2-5 on page 2-9) are used in all the application
modules that "tamp" the label onto the product. When a label is fed from
the printer onto the tamp application module, it passes under the tamp
pad. The tamp pad retains the label in position (with the help of vacuum),
until the time it is to be applied onto the product. Tamp pads are
specifically manufactured to suit the size of the labels being applied, and
the style of the product. Typically, the tamp pad details are specified at the
time of placing an order for the LPA, or the application module. The
details can also be specified at a later date so that the tamp pad can be
used in the same machine for different sizes of the label.

•Tamp module

•Tamp jet module

• Heavy duty long stroke tamp module

• Adjustable swing arm tamp module, and swing arm tamp module

• Two panel tamp module

Tamp pads comprise two major parts, a pad and a grid. In some cases,
they are also fitted with a flexible coupling.

• The pad has a series of holes through its body that allows air to be
drawn in by vacuum, to enable the label to stick to it.

• The grid contains a vacuum chamber to allow uniform distribution of
vacuum over the tamp pad. It also contains a series of fixing holes to
allow it to be fastened to the application module.

• The flexible coupling allows tamp pads to conform to angular
irregularities generated by variable product placement or shape.

Blow application module is an "Air jet" device that consists of an
extraction fan that is used to create vacuum within a vacuum box. The
vacuum created inside the box holds the label to the vacuum grid. The
vacuum level is adjusted by a baffle, located on the side of the vacuum
box. Air tubes blast air from the pneumatic source to apply the label onto
the product. The position of the air blast tubes on the vacuum grid can be
adjusted to apply labels of different shapes or sizes to the product.

During label printing, the label is transferred to the underside of the
vacuum grid, guided by the air assist assembly. The vacuum created
within the vacuum box holds the label in position until the product is
detected by the product detector. When the product moves under the
vacuum box, the air blast tubes release air with force, and apply the label
to the product.

Tamp jet works on the same principle as the tamp module, except that a
blast of air blows the label onto the product, before the tamp pad touches
the product. The tamp jet can be used as a regular tamp because the jet can
be used to enhance the label tack and its release from the pad. The flexible
tamp pad coupler (Figure 2-9 on page 2-13) allows the tamp pad to
conform to product misalignments of up to 20% in a fixed position or a
combination of two adjacent axes. This allows the pad to be in full contact
with the product. The tamp jet module can accommodate tamp pads of
sizes ranging from 100 mm in length by 60 mm in width to 210 mm in
length by 185 mm in width, by simply changing the position of the flexible
coupling on the tamp pad adapter plate.

The HDLS tamp module is the same in operation and function as any
other linear tamp, except that is a heavier duty version, uses a 32 mm
diameter bore air cylinder, and possesses the ability to travel up to 800
mm in distance.

As in the tamp jet module, the HDLS tamp module is fitted with a flexible
tamp pad coupler. The flexible tamp pad coupler allows the tamp pad to
conform to product misalignments of up to 20% in a fixed position or in a
combination of two adjacent axes, which allows the pad to be in complete

The HDLS tamp can accommodate tamp pads of sizes ranging from 100
mm in length by 60 mm in width to 210mm in length by 185 mm in width.
This is done by changing the fixing position of the bearing block, and
adding or subtracting spacer blocks between the mounting plate and the
bearing block, as required.

The swing arm tamp is a fixed swing tamp module and uses the principle
similar to that of the tamp module. As in the tamp module, the tamp pad
is fitted on a fixed length arm that is swung out to the side or the front, on
a fixed pivot point, to apply labels to the product on either the leading or
the trailing face. It is also equipped with a damper that allows controlled
return operation at all speeds.

The swing arm tamp module is not fitted with the flexible tamp pad
coupling. However, it uses the standard range of tamp pads, whose size
must be specified at the time of placing an order.

When a corner wrap operation is initiated, it feeds out a label onto the
dispense pad. Due to the product movement and its associated forces, the
label is tacked to the initial leading face of the product by a roller. The
label is then applied progressively from the lead face onto the adjacent
face of the product, while the dispense pad and the roller are repositioned
around a pivot point and are fixed to the machine.

Shaft Encoder

A shaft encoder (Figure 2-15 on page 2-20) is used when the speed of the
product line is variable. The shaft encoder translates the linear movement
of the product line into generated drive pulses that are fed to the LPA. As
the varying rate of pulses is proportional to the product line speed, the
LPA is able to determine various delays and timing sequences. This
ensures that the machine operates precisely, even when the product line
speed is variable.

To choose the shaft encoder, consider the following criteria:

• Remote OCP

• Print engine data cable

• Smart tamp sensor

• Machine stand assembly

• Remote computer

• 1.00-15.00 PPmm, (2500 or 5000 PPR when fitted with a 400 mm
circumference (5.013" dia) contact wheel

• Single or Dual Quadrature output, which must rotate clockwise,
because the readings can be generated only in that direction

Product Detector/s

The product detector (Figure 2-16) is used to determine the presence of an
approaching product. Two product detectors can be used, to determine
the presence and the speed of the product respectively. Once the product
has passed by in front of the second detector, the product detector
generates a signal to the LPA to initiate a pre-programmed delay to start
the operation cycle.

Smart Tamp Sensor

A smart tamp sensor (Figure 2-22 on page 2-27) is a divergent beam type
that is fitted to a tamp pad and is used to detect the presence of a product
before the tamp pad makes physical contact with the product. When the
sensor detects the product, it generates a signal to adjust the "tamp
overrun" setting, creating an additional time period, before the tamp
cylinder returns home. The adjustment of the "tamp overrun" setting
allows finer control over the gap between the product and the tamp pad.
Once the "tamp overrun" time expires, the tamp jet function actuates at the
same time, as the tamp is directed back to the home position.

Main Controls of the
LPA

LPA Controls

This chapter contains the following topics:

• A description of the LPA controls

• A description of the print engine controls

The LPA controls are used to control the air flow and pressure of the
pneumatic functions of the machine.

Pneumatic Pressure and Flow Control

The pneumatic controls comprise the following:

• System air pressure - controlled via the filter/regulator assembly

• Air assist air flow - controlled via a thumbscrew-adjusted, air flow
fitting on the pneumatic module

• Tamp cylinder speed control airflow - controlled via a thumbscrew­operated, flow control fittings attached to the air cylinder

• Tamp pad vacuum - controlled via a thumbscrew-operated flow
control valve, fitted to the air module that regulates the air flow into a
vacuum generator/venturi

• Tamp jet control

• Vacuum box - vacuum is controlled via an adjustable baffle on the
side of the vacuum box

Note: The above controls will need to be adjusted to suit the application module
fitted.

The pressure control, complete with pressure gauge, controls the overall
pressure in the machine including the pressure in the air blast tubes, in
case of "blow" or "air jet” modules. The setting of the control for "blow" or
"air jet" modules depends upon the size of the label, the speed, and
distance at which the product passes the applicator.

Rev AA LPA Controls 3-1

P3400 Operator Manual

Note: Adjusting the pressure control will also affect the air assist flow rate. In
general, the air pressure is set at 5.5 bar (80 psi).

System Air Pressure

Note: The filter regulator shown is for the purpose of illustration only and may
vary from the one supplied with the pneumatic module.

The system air pressure (refer Figure 3-1 on page 3-3) is increased by
turning the adjuster knob in the indicated direction, until the desired
pressure is reached on the pressure gauge. To decrease the pressure, turn
the adjuster knob in the opposite direction.

The recommended operating pressure is 5.5 bar (80 psi), for most
applications.

Note: Cylinder speed should NOT be adjusted using the main system pressure.
Instead, use the flow restrictors fitted to the air cylinders.

The vacuum box (Figure 3-6) has the following components:

Note: The vacuum box components can be adjusted, depending upon the label
size:

• Adjustable baffle: It is a perforated disk that is used to change the
vacuum level at the vacuum grid. As the baffle is rotated, the holes in
the vacuum box can be opened to decrease the vacuum level in the
vacuum box, or closed to increase it.

Note: Large labels may require a lower vacuum level than small labels.

• Air blast tubes: These are used to route the high pressure air to blast
the labels onto the product. They are placed in different positions/
patterns on the vacuum grid, depending upon the label size and
shape. All the air blast tubes may not be needed. Unused tubes must
be stored in the manifold.

PERSONAL INJURY. Before altering the position of the blast tubes,
ensure that the machine is switched off, and all air pressure is
exhausted.

The following section provides information on generalized settings for the
initial setup of the vacuum box. The air tubes may be required to be
moved to optimize the label positioning. A blanking plate/grid mask can
be fitted to the vacuum grid when small labels are used. This increases the
effective vacuum around the area of the label.

Note: The pattern of the air blast tubes on the vacuum grid does not need to be
symmetrical to produce the most efficient label application. Often a pattern,
configured to bend the label during application, can yield acceptable results. It is
not necessary to use all the air blast tubes if the label is not a large one. Start by
using the tubes suggested in the following figures, and adjust as required to gain
optimum performance.

Air Blast Tubes - Rectangular Label

For rectangular labels, the objective is to place the label down in a single
flat manner. The center-based tubes are used to first place the center of the

Air Blast Tubes - Oval Label on Moving Product

For moving label applications, the purpose of positioning the air blast tube
is to apply the front end first, followed by a wiping action as the product
continues to move away from the labeler. Ensure that the label does not
flip over. Otherwise, it may cause a ripple. The amount of bias towards the
front of the label will depend upon the speed of the production line, and
the distance of the applicator from the product. Adjustment of the air
pressure can also enhance the label delivery (refer Figure 3-13).

Print Engine Controls

The control panel of the print engine contains controls to monitor and
operate the print engine. The position of the controls may vary, depending
upon the type of print engine fitted. It comprises a keypad, LCD display,
and LED indicators. Using these three together, the operator configures,
monitors, and operates the print engine. The print engine may also be
configured and operated remotely from a controlling computer.

The status indicators, located on the print engine's control panel, indicate
the following machine operation/fault conditions, whenever they glow:

• Power On - indicates that the machine is switched on.

• Label/Media - indicates when the label web has run out. If the
indicator glows when the label has not run out, check the label
threading that passes through the sensor. The sensor may not have
detected the label because it was not threaded correctly.

• Ribbon- indicates when the ribbon has run out. If the indicator glows
when the ribbon has not run out, check the ribbon threading that
passes above the sensor, inside the print engine.

• Error - indicates when a print engine error has occurred. This is
combined with an error message displayed at the control panel, for
example, printhead cover open.

Getting Started

This chapter describes the procedures to get started with using the LPA:

• Loading a ribbon into the print engine

• Loading a label roll

• Switching on the machine

• Setting up the machine

•Configuring printer/applicator settings

• Starting production

Loading a Ribbon into the Print Engine

To load a new ribbon into the print engine, proceed as follows:

1 Remove the new ribbon from its packaging.
2 Unwind approximately 300 mm of ribbon from the reel (an initial

length of the ribbon is ink free and is termed 'leader').

3 Fit the new ribbon to the unwind spindle, and ensure the following:

- The reel is pushed fully onto the spindle.

- The dull ink side of the ribbon must face downwards as it travels
through the printhead assembly.

4 Lift the printhead lever and make space to slide the ribbon on the

printhead.

5 Thread the ribbon around the rollers and over the printhead, and

extend the threading to the empty rewind reel by following the
threading diagram attached to the print engine.

6 Secure the ribbon to the reel with an adhesive tape to prevent from

slipping.

7 Wind excess ribbon onto the rewind reel, ensuring that the ribbon is

not torn or wrinkled.

ribbon.

8 Once the ribbon is loaded, lower the printhead lever to the closed

position, and close the print engine cover.

Note: Run a print test to check the print quality each time you load a new
ribbon.

Loading a Label Roll

To load a new label roll, proceed as follows:

1 Fit the label roll (Figure 4-1 on page 4-3) to the unwind reel, and

secure it with the quick release locking collar. Ensure that the
direction of the unwind reel is the same as that seen on the threading
diagram.

Configuring the LPA Settings

To configure each module associated with the LPA, follow the instructions
provided under each application type.

Blow Setup

The only difference between “blow” and “blow and print” is that the next
label feed starts at the beginning of the blow cycle, instead of at the end.
This will reduce the overall cycle time. However, it should be used with
caution and only with short blow periods.

To set up the blow module, proceed as follows:

1 In the Configure menu, select Mode of Operation.
2 Set Basic Mode to Blow.
3 Set Alternate Mode to Normal and set all other sensors to Disabled.
4 Save the configuration, and press Exit when prompted.
5 In the Top Level menu, set the Blow Time to 100ms. This can be

shortened later to optimize performance.

6 Set the Blow Flight Time to 20 ms. This can be adjusted later to

optimize flight time compensation, if activated.

7 Set the Line Speed to the actual conveyor speed, for example, 1000

mm/s.

8 Set the Product Sensor Distance equal to (Blow Flight Time x Line

Speed), that is, 0.020 X 1000 = 20 mm. This is the minimum distance
for the blow module with the conveyor running at 1000 mm/s.

Note: Product Sensor Distance is the distance between the product at the
labeling position, and its position when the product sensor first notices it.

9 Set Air Assist Delay to zero.
10 Set Rewind Overrun to 500 ms.
11 Save the settings in one of the memories (1 through 8).

Note: Once the settings are saved, they can be used for other print jobs also.
You can reconfigure these settings, whenever necessary.

12 Download a number of labels to the print engine. One label should

feed onto the blow grid, provided the air assist and blow box vacuum
have been set correctly.

13 Cycle the machine by triggering the product detector. The label will

blow off the grid and another label will feed onto the blow grid.

4-12 Configuring the LPA Settings

Rev AA

Blow time can be adjusted based on the frequency of the label being blown
onto the product. This will reduce the overall air consumption during
normal operation.

Tamp Setup (STD, FLEX AND HDLS)

To set up the tamp module, proceed as follows:

1 In the Configure menu, select Mode of Operation.
2 Set the Basic Mode to Tamp.
3 Set the Alternate Mode to Normal, and set all other sensors to

Disabled.

4 Save the configuration, and press Exit when prompted.
5 In the Top Level menu, set the Tamp Flight Time (Tamp stroke

6 Set Tamp Return to the same time as that of Tamp Flight Time.
7 Set the Line Speed to the actual conveyor speed, for example, 300

mm/s.

8 Set Product Sensor Distance equal to (Tamp Flight Time x Line Speed)

that is, 0.320 X 300 = 96 mm. This is the minimum distance for a 160
mm tamp with the conveyor running at 300 mm/s.

Note: Product Sensor Distance is the distance between the product at the
labeling position and its position when the product sensor first notices it.

9 Set Air Assist Delay to zero.
10 Set Rewind Overrun to 500ms.
11 Save the settings in one of the memory directories (1 through 8).

Note: Once the settings are saved, it can be used for other print jobs also.
You can reconfigure these settings, whenever necessary.

12 Download a number of labels to the print engine and one label should

feed onto the tamp pad, provided the air assist and vacuum have been
set correctly.

13 Cycle the machine by triggering the product detector and adjust the

air cylinder flow controls, until the cylinder just extends to its full
stroke, and returns to its home position just in time for the next label
to feed onto the pad smoothly.

This procedure will set the cylinder linear speed to 500 mm/s, which is
considered to be the optimal speed for most tamp applications. Faster or

Corner Wrap Setup

The corner wrap module functions from the same signals that the tamp
module uses, and is in the same set up, except for the following:

In the tamp, the label feeds out to the vacuum grid, awaiting a product
detect signal. Once the signal is received, the grid advances out. When the
previous product clears the grid path, the grid stays out waiting for the
next product. As the product passes past the corner wrap module, a roller
stacks the label to the product, and rolls the label down on to the leading
face and then the adjacent face of the product, while displacing the
vacuum grid. Once the roller has rolled over the trailing end of the label,
the unit times out and returns home, ready for the next label feed.

To set up the corner wrap module, proceed as follows:

1 In the Configure menu, select Mode of Operation.

2 Set the Basic Mode to Tamp (this is the same as corner wrap).

3 Set Alternate Mode to Normal, and set all other sensors to Disabled.

P3400 Operator Manual

4 Save the configuration, and press Exit when prompted.

5 In the Top Level menu, initially, set the Tamp Flight Time equal to the

maximum 3.20 seconds (this time can be reduced to ensure that the
grid returns, and the label loads in time for the next product)

6 Set Tamp Return to approximately 0.50 seconds (this time period

should allow the grid to settle ready for the next label. Use the
cylinder flow restrictors to provide smooth and controlled movement)

7 Set the Line Speed to the actual conveyor speed, for example, 300

mm/s.

8 Set the Product Sensor Distance equal to (0.5 seconds x Line Speed)

that is, 0.5 X 300 = 150 mm. This is the minimum distance for a 0.5
second "out time" for the grid to swing out, in time for the grid to be in
position for the approaching product with the conveyor running at
300 mm/s.

Note: Product Sensor Distance is the distance between the product at the

a smooth and controlled manner, not disturbing the label on the grid.
The grid should return to its home position just in time for the next
label to feed onto the pad smoothly.

Note: The tamp flight time needs to be long enough for the grid to swing into
position, to be ready for the approaching product and for the roller to roll the
full length of the label. Once this has been achieved, the grid should return
within the 0.5 second tamp return time.

Adjustable Swing Arm Tamp Application Module

The adjustable swing arm tamp uses a similar principle as tamp.
However, the tamp pad, fitted on an adjustable length arm is swung out to
the side, about a 40 mm bore diameter, equivalent to a rotary cylinder, to
apply labels to the product in a similar manner to the tamp. It can be
equipped with a choice of dampers allowing controlled operation at low
speeds, and as well as at higher speeds.

Air Assist Tube

This tube is located under the peel tip and works along with the label feed
to assist in transferring and positioning the label from the peel edge to the
applicator.

Air Cylinder

This is a pneumatic device with an internal piston. The piston has a
connecting rod to the tamp pad, which is coupled mechanically through a
connecting block. When air is applied to the air cylinder, it applies
pressure to the piston, and extends the tamp mechanism towards the
product to be labeled.

Assist Delay

Adjusts the time from beginning of label dispense to the time the air assist
is activated.

Blow Application Module

Blow application module is an "Air jet" device containing an extraction fan
that is used to create a vacuum within a vacuum box. The vacuum inside
the box holds the label to the vacuum grid. The vacuum level is adjusted
by a baffle, located on the side of the vacuum box. Air tubes blast air from
the pneumatic source to apply the label to the product. The air blast tubes
can be moved on the vacuum grid to apply labels of different shapes or
sizes to the product.

Dancer Arm Spring

This spring provides tension for the dancer arm.

Drive Roller

The roller provides the force for advancing the label liner. It is a part of the
print engine and is electronically controlled by the control card inside the
back cover.

Faceplate

This is the metal place that supports all the machine components required
to unwind the label roll, peel the labels, apply them to the product, and
rewind the label liner.

Rev AA Glossary-1

P3400 Operator Manual

Guide Rods

These rods are coupled mechanically through a connecting block, to the
tamp pad. They ensure true vertical movement of the tamp mechanism.

Heavy Duty Long Stroke Tamp Application Module

The HDLS tamp is the same in operation and function as any other linear
tamp, except that is of a heavier duty, uses a 32 mm diameter bore air
cylinder and has the ability to travel up to 800 mm in distance.

Idler Roller

These are the rollers that guide the label liner along its thread path.

Label Printer/Applicator

Any device designed to print information on a label, and later, apply the
label to an object.

Label Guide Collar

These devices are attached to the idler rollers to facilitate proper tracking
of the label liner.

Label Length

This is the overall length of the label from leading edge to trailing edge.

Label Liner (Web)

This is the silicon coated material to which the pressure sensitive label is
adhered.

Label Peel Plate/Peel Tip

This plate/tip is designed and positioned to separate labels (peel off) from
the label liner when the label liner is pulled around it. Labels can be
applied only after they are peeled. Label peel plate/tip is a part of the
print engine. This part is also known as peeler plate, peel tip, peel edge,
peeler bar, and demand plate.

Label Repeat

This is the distance from the leading edge of one label to the leading edge
of the next label (on the label liner).

Label Rewind

This is the subsystem that rewinds the spent label liner.

Label Rewind Dancer

This device controls the tension applied to the rewind roll. It helps to
absorb the variation in liner waste take-up that occurs as a normal
function of the incremental label advancing system.

Label Sensor

This infra-red, thru-beam detector senses the opacity of the label liner
before the label is removed. In doing so, it also senses the spaces between

Glossary-2

the labels and provides label stop control. The sensitivity of this sensor is
adjustable, and the stopping position of the label, which is relative to the
peel edge, is adjusted electronically.

Label Size

This is the dimension of the label (width x length).

Label Unwind

This is the subsystem that unwinds the label supply roll to facilitate label
application.

Label Unwind Dancer

This device controls the tension applied to the unwind roll. It helps to
absorb the shock that occurs as a normal function of the incremental label
advancing system.

Label Unwind Flange

These disks hold and retain the label supply roll.

Label Unwind Spindle

This shaft holds the label flanges that contain the label roll.

Pressure Sensitive Label

A material, cut to a predetermined size with adhesive (sensitive to contact)
applied on its one side. These are usually supplied in rolls or fan fold.

Power Indicator

When the power indicator is lit, it indicates that power is on and supplied
to all circuits.

Product Detector

The product detector, normally located on the product conveyor, provides
the sequence start signal upon detecting an approaching product on the
conveyor. The detector is positioned relative to the label peel tip for
correct application. This position is determined by the speed of the
conveyor, length of the product to be labeled, and the desired position of
the label on the product. The detector should be carefully positioned to
operate the applicator at maximum speed.

Product Sensor

It receives input from the product detector.

Rewind Lock-Pin

This is the U-shaped pin that is used to retain the spent label web on the
rewind roll (mandrel).

Rewind Roll

This is the mandrel provided to store the spent label web.

Rev AA Glossary-3

P3400 Operator Manual

Shaft Encoder

A shaft encoder kit is available to synchronize the dispense speed of the
label with the line speed of the product.

Tamp Application Module

This is a label applicator that uses an air cylinder that extends to apply the
label on to the object and retracts to its home position. The label is
dispensed onto a tamp pad (through the air assist mechanism) and is held
in place by vacuum created within the tamp (by the pneumatic module).
When the product moves under the tamp, the tamp assembly extends and
applies the label to the product. Immediately the tamp retracts and is
ready for another extension.

Tamp Pad

Tamp pad is a part of the tamp applicator that holds the label during the
application process. There are holes in the pad through which the air is
sucked, creating vacuum inside the tamp. The vacuum helps the tamp to
hold the label till the air cylinder extends the tamp and affixes the label on
to the object. Each tamp pad is manufactured for a specific label size and
should not be used for a label size that does not match.

Tamp Jet Application Module

Tamp jet works on the same principle as a tamp, except that a blast of air
blows the label onto the product prior to the tamp pad (not shown)
touching the product. The tamp jet can also be used as a regular tamp, as
the jet can be used to enhance the label tack and release from the pad.

Swing Arm Tamp Application Module

The Swing arm tamp is a fixed swing tamp module and uses a similar
principle as tamp. However, the tamp pad, fitted on a fixed length arm is
swung out to the side or the front, about a fixed pivot point, to apply
labels to the product, in a similar manner to the tamp. It is equipped with
a damper, allowing controlled return operation at all speeds.
