Encollage supérieur et inférieur de boîtes plieuses par application de buses sans contact

L'augmentation de la vitesse de la production ainsi que les exigences accroissantes de qualité, flexibilité et productivité, montrent les limites d'une application de colle traditionnelle par disques.

 

Le système Baumer hhs Vario-glue permet un encollage au millimètre, même sans contact avec la coupe à chaque vitesse. Le système fermé diminue le temps de nettoyage et de montage; il permet un encollage sans rebut, d'un arrêt de machine jusqu'à une vitesse plus de 700 m/min et rend même possible la fabrication du produit le plus compliqué. Pour cela, on emploie un système modulaire consistant d'un approvisionnement de colle à haute pression, de têtes d'application électro-magnétiques à actionnement rapide et résistantes à l'usure ainsi que d'un programmateur facile à manier, qui permet un changement de commande en appuyant sur un bouton.

 

Chaque système peut être élargi à l'aide de modules supplémentaires. Des systèmes d'application inférieurs avec jusqu'à deux buses ainsi que des têtes d'application multiples à programmer individuellement sont disponsibles. On peut même réaliser une application combinée de colle froide et chaude.

 

En option, nous vous offrons en supplément un système intégré pour la détection de traits de colle, vous garantissant une production parfaite. When needed with code reading, glue verification or cameras.

Gluing of folding cartons

Folder gluers process carton blanks from die cut sheets, folding and gluing them into a finished product. In the case of cartons for branded goods or pharmaceutical products, the folding cartons are subsequently erected and filled in automatic packing machines. Many cartons require folding at several points, in and transversely to the machine direction, before the glue is applied. The carton is prepared for trouble-free erection in this way.


Use of hot melt

Hot melt is characterised by its particularly fast curing and its ability to even glue impermeable materials, such as foils. In special designs, it is also used together with dispersion glue. In this way, the point of adhesion is rapidly fixed, so that the two glued surfaces do not shift, or even come apart, before the cold glue has cured.

 

Use of cold glue

Cold or dispersion glue is used because it is inexpensive, simple to process and offers long-term stability of the point of adhesion. The robust glue application heads from Baumer hhs guarantee the greatest possible production reliability with minimum maintenance. The application quantity is adapted to suit the product and the machine speed at all times. The most minute quantities of glue are applied in dot mode.

 

Securing product quality

Optional monitoring systems from Baumer hhs examine each passing product for predefined criteria. Code readers identify the packaging in order to avoid mix-ups, and glue sensors check the correct application of the glue before closure. Defective products are ejected without stopping the machine.

Every system can be expanded to include additional modules. Bottom gluing units with one or two nozzles are available, as are individually programmable multi-application heads. Combined application of cold glue and hot melt is also possible.

An optional, integrated system for code reading, side seam detection or data logging ensures defect-free production. With cameras on request.

 

 

Sample counter
The sample counter counts the loaded folding cartons with the help of a light barrier.
Samples are randomly determined by the system throughout the production process and removed manually after reaching the tracking point. The number of samples to be taken is specified in the system.
For use with all folder gluers.
