LTP - LTPV Product description

Product description

Product name

LTP/LTPV = Light Touch Pneumatic / Light Touch Pneumatic Vacuum

Light Touch Light Touch means that the applicator reverses shortly after it encounters resistance,

i.e. a product. This has the advantage that it also enables products of different heights

to be labeled without needing to adjust the applicator.

Pneumatic The LTP/LTPV is driven by compressed air.

Vacuum (LTPV only) The label is held to the plastic plate on the underside of the applicator by

suction and the air stream of a support air jet.

In the LTP, the suction onto the suction plate is generated by a blower that is mounted

at the top end of the applicator housing.

Intended Use of System

The LTP/LTPV applicator is a device for automatic attachement of self-adhesive

labels, which are supplied to the applicator by one of the following label dispensers or

print & apply machines.

Dispensers:

•ALS20x

•ALS256

Print & apply machines:

ALX 92x

The LTP/LTPV is firmly attached to the respective machine. In contrast to direct

dispensing from the dispensing edge of the machine onto the product, the LTP/LTPV

can bridge distances of up to 20 cm between dispensing edge and product. The „light

touch“ function enables the LTP/LTPV to attach labels on products with varying

heights.

Installation position Permissible installation positions for the LTP/LTPV are:

•Vertical, if application takes place from top to bottom (the product is located below

the printer/applicator); Application from bottom to top only if a dust protection,

specific to the application, is supplied by the integrator.

•Horizontal (the product is located next to the printer/applicator)

Configurations

The LTP/LTPV is available in both right-handed and left-handed versions. LTP/LTPV

and dispenser must be of the same handedness, that is both must be RH or LH ver-

sions.

Furthermore, the LTP/LTPV is available in two version:

• For mounting to the base plate of an ALX 92x

• For mounting to the dispensing edge holder for L-shape dispensing edges at the

following machines: ALS 20x/256

LTP - LTPV Product description

System requirements

Compressed air Compressed air connection with 4-6 bar must be available. If the pressure is higher, a

pressure reducer must be installed (available as accessory, article no. A9398).

ALX 92x • ALX 92x with standard dispensing edge and firmware version 3.40 or higher.

• Installed applicator interface (optional) with firmware version 1.03 or higher. If the

applicator interface was retrofittet, pay attention that the D-Sub 15 connector for

Avery applicators (top side of the front hood) is available.

ALS 20x • ALS 204, ALS 206 or ALS 256 with fixed L-dispensing edge and firmware version

1.10 or higher.

• Control by standard signal interface or by applicator interface (firmware version

1.18 or higher). The applicator interface is available optionally.

Functionality

The LTP/LTPV applicator is an additional module to be mounted to one of the above

named label dispensers or print & apply machines (see chapter Intended Use of Sys-

tem on page 2). The device takes over self-adhesive labels from the dispensing

edge of the dispenser/print & apply machine, moves each of the labels to the product

in a linear movement and attaches it to the product.

The label is held by a pressure plate that is driven by a pneumatic cylinder between

home position and end position.

In home position, the label is taken over from the dispenser or the print & apply

machine. The arrival of the pressure plate in home position is detected by a sensor at

the pneumatic cylinder of the applicator. The label is peeled off the backing paper by

the dispensing edge and is pushed under the pressure plate, where it is sucked on by

a vacuum. Additionally, the label is blown onto the pressure plate by an air stream from

the support air nozzle. Afterwards, the pressure plate moves to the end position, whe-

re the label is attached to the product.

The arrival in the end position is detected by 4 sensors which are integrated in the

pressure plate. The sensors are activated, as soon as the pressure plate presses

slightly against the product. This „light touch“ function enables the LTP/LTPV to label

products with varying heights and especially sensitive products.

General safety notes

• Operating air pressure: 6 bar.

• The applicator must not be operated outdoors or in EX-areas.

• The applicator may only be installed and started up by authorized technicians.

• Lay cables and compressed air hoses in a way that nobody can stumble over it.

• Fix pneumatic hoses against lashing.

• Immediately replace defective pneumatic hoses.

• Only authorized technicians who are familiar with the associated hazards are per-

mitted to repair the applicator.

• Check the applicator regularly for faulty components. Immediately replace any

defective components with OEM parts! This reduces any safety hazards resulting

from the use of low quality parts.

• The on-off valve of the applicator must be set correctly. After switching on the com-

pressed air supply, the vacuum plate of the applicator must move slowly to the

home position. If the vacuum plate moves abruptly, the on-off valve must be

checked regarding a defect or a misalignment of the valve, see chapter Setting the

on-off valve on page 23.

• Never modify the design of the applicator (e.g., by installing a higher capacity

pneumatic cylinder). If the applicator is altered without authorization or used in an

unintended manner, all liabilities for damage and any other guarantees from the

manufacturer shall be rendered null and void.

WARNING!

Danger of cuts and crush injuries especially at the following points:

• Between moveable vacuum plate and dispensing edge.

• Between the guiding rods of the applicator.

• Between vacuum plate and conveyor belt, if present.

Never operate the applicator without the protective equipment. See chapter Con-

necting an interlocking guard on page 8.

Never remove or bypass the protective equipment.

Never touch the applicator while it is moving.

When adjusting the system, make sure that the applicator is not actuated unin-

tentionally.

LTP - LTPV For your safety

Connecting an interlocking guard

The illustrations in this chapter show exemplary a LTP at an ALS 20x RH labeller

(pictured without cables and hoses). The following instructions apply equally to all

other LTP/LTPV versions.

According to the EC machinery directive, the LTP/LTPV are partly completed

machines. In order that the completed machine matches the health and safety requi-

rements of the machinery directive, LTP/LTPV must be safeguarded against access

by an appropriate safeguarding device 1 (see [5]).

Connect the interlock switch [5[5D] of the safeguarding device to the connector [4]

delivered with the applicator.

Plug the connector to the LTP/LTPV [3].

Operation of the LTP/LTPV without the described safeguarding device shall be

regarded as abnormal use. Avery Dennison assumes no liability for damage due to

abnormal use of the printer.

[3] Connecting the interlock switch (A) of the safeguarding device (or an emergency-stop switch) to a LTP/

LTPV (at an ALS 20x).

[4] Plug that comes with the LTP/LTPV for connecting an interlock switch to the

LTP/LTPV (article number: A102076).

1) Movable interlocking guard according to EN ISO 12100-1, 3.25.4

Warning notes on the device

[6] Warning note on the LTP/LTPV.

CAUTION!

Warning notes on the machine provide important information for the operating per-

sonnel.

Do not remove warning notes.

Replace missing or illegible warning notes.

Warning note Meaning Article no.

The warning note „pinch point“ warns you of

the danger posed by movements of the

machine; they can cause crush injuries.
