The new Alpha V40 is an automatic, all purpose label applicator for quick, depebdable, trouble-free labeling of a broad range of products and packaging.

The new display controller has many new functions as standard. For example, as many as 30 label formats can be stored in the memory. You can change over to other label formats quickly as the memory condains all required information. For example: Length of label, application speed, opacity and placement of label. The system does not have to be calibrated. This saves time, and avoids risk of habdling mistakes. The liquid crystal display is backlit, and incorporates a label counter. The functions of the sensors are always displayed on screen in real-time. The current application speed is indicated as metres per minute; it may ve adjusted while the applicator is still in operation.

Any problems are indicated by a display message. You can select various languages on the display dialogue. Volgate free contacts are proviced for connection to the PLC. In case of a missing label on the web, an automatic compensation is made which prevents double labeling or missing a product.

A number of control profiles for the applicator are resident in the Alpha V40 controller, which can be selected from the display. The advantage of this is the fast and easy changing to other applicator types, without the need to change the control system. The controller backup function (option) enables you to copy all variables (e.g. label parameters) simply and reliably, via the serial interface to a back-up controller.

You are free to configure the sensor inputs, all usual sensor types (e.g. photo sensors with NPN- or PNP-outlets) can be connected using an M12 cable.

By using the "trigger delay function" the exact positioning of the label can be controlled without the need to adjust or move the product detection sensor.

Products of irregular shape may cause unwanted multiple trigger signals, they can be masked out. Options, such as shaft encoder, warning lights, sensors, etc., can be retrofitted simply by Plug & Play.

The Alpha V40 is availlable in the following versions: Wipe-on, Tamp-on, Tamp-blow and Blow-box.

This means that the requirements of most labeling applications can be met, with one modular system. The system is supported by its own cast aluminium casing, rendering it resistant to distortion. The centralised suspension of the dispenser tongue (Wipe-on version) allows automatic adjustment for any change in the height of the products, without causing a mismatch of length in the label field. In the Wipe-on version, the labels are peeled off from the carrier, and applied to the product/packaging by a precise stepping motor. With the Tamp-blow version, the dispensing tamp travels over a linear system to the product by a pneumatic drive. Another version of the tamp-blow system pivots the tamp pad by 90° rotation to the face- or backside of the product. The label is blown onto the moving or stationary product, with no physical contact.

The contact less Tamp-blow method offers important advantages:

• No wear in the region of the tam
• Can be fitted to any direction of conveyor
• Products can be labeled "on the move"
• Applies labels to sensitive and irregular-shaped surfaces
• No start-stop synchronisation with the conveyor is required

The basically provided blow-on function guarantees s sure label application also onto uneven and arced surfaces. The Tamp-on applicator is spingmounted and presses the label onto the surface of the slowly-moving or stopped products. Preferred use: Difficult surfaces, for example sawn timber/wood. With the Blow-box applicator, the label is blown straight on the passing product using a strong air jet (no contact). This allows the applicator to achieve very fast cycle times. The distance from the blow-box to the product must be between 6 and 20 mm to ensure accurate label positioning. No matter what the method may be, the products are labeled precisely and quickly. The accuracy of placement is up to ± 1 mm.

Keeping the applicator and its control system separate makes for a smaller-sized mchine, and greatly facilitates the integration into existing production lines. The applicator may be converted from a right-hand to a left-hend version, thanks to the symmetry of the design. This provides the maximum degree of flexibility.

The compact applicator can be installed in any required position. The applicator has removable guide rollers which allow easier handling and cleaning.

A full roll of labels can be changed in approximately 30 seconds. The robust design of the system guarantees reliable operation in continuous production. The Alpha V40 can be supplied fitted with special-type applicators with tamp-blow, blow-box, and other options for all-round and precision labeling. Complete special labeling systems incorporating techniques for handling the product in special applications are obtainable, on request.
