LA-TO / LA-TO XL Product description

Product description

Product name

LA -TO is the abbreviation for "Label Applicator Touch-On". The abbreviation ‘TO’

(touch on) distinguishes this applicator from other application techniques such as

‘blow on’ or ‘swing on’.

The LA -TO XL is a LA -TO with more stroke length.

For reasons of clarity in this manual, the LA -TO XL is only mentioned separately, if its

specifications or its use differ from the „standard“ LA -TO.

Intended Use of System

The LA-TO 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:

•ALS 20x

•ALS 256

•ALS 30x

Print & apply machines:

•ALX 73x

•ALX 92x

The LA -TO is firmly attached to the respective machine. In contrast to direct dispens-

ing from the dispensing edge of the machine onto the product, the LA-TO can bridge

distances of up to 18 cm (LA -TO XL: 38 cm) between dispensing edge and product.

Configurations

The LA -TO is available in both right-handed and left-handed versions. LA -TO and dis-

penser must be of the same handedness, that is both must be RH or LH versions.

Furthermore, the LA -TO is available in two versions:

•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: ALX 73x, ALS 20x/256, ALS 30x

System requirements

Compressed air •Compressed air connection must be available

•Mounting surface for pressure controller: See Installing the pressure regulator 

on page 16

ALX 92x •ALX 92x with standard dispensing edge and firmware version 5.33 or higher.

•Installed applicator interface (optional) with firmware version 1.23 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.

Functionality

The LA -TO 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 ma-

chine. 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,

where the label is attached to the product.

The arrival in the end position is either detected by a sensor (sensor controlled), or by

reaching the end of a the time interval set in the parameter menu (time controlled, see

chapter Settings on page 19).

All products have to be of the same height.

General safety notes

•Operating air pressure: 4-6 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 de-

fective 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 Setting the on-off

valve on page 26.

•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 9.

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.

Connecting an interlocking guard

The illustrations in this chapter show exemplary a LA -TO at an ALS 20x RH labeller

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

other LA -TO versions.

According to the EC machinery directive, the LA -TO is a partly completed machine.

In order that the completed machine matches the health and safety requirements of

the machinery directive, LA -TO must be safeguarded against access by an appropri-

ate safeguarding device 1 (see ]).

Connect the interlock switch D] of the safeguarding device to the connector A] de-

livered with the applicator (see E]).

Plug the connector to the switch box B].

Operation of the LA -TO without the described safeguarding device shall be re-

garded as abnormal use. Avery Dennison assumes no liability for damage due to ab-

normal use of the printer.

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

LA -TO (at an ALS 20x).

[4] Plug that comes with the LA -TO for connecting an interlock switch to the

LA -TO (article number: A102076).

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