The world of blisters is changing

07-23, 2015


The new robotized integrated blister line Integra 520V was presented for the first time at Achema 2015. The machine with balcony design is a mere 10 meters long, so very compact, and it combines two machines: a thermoformer (520 blisters/min in Alu+PVC/PVDC/PET/Alu/other materials) and a cartoner (500 cartons with tuck-in or glued flap closure and various other combinations).

Integra 520V is the bigger model of Integra 320 showcased at the last edition of Interpack. This new model features not only the innovative functions of Integra 320, but also new pushers, a drum-type carton opener to deal with high speeds and a new leaflet pick-and-place system. The final result is an ideal machine for single-blister cartons; it is easy to clean and to changeover size thanks to the fact that the product feeding area is separate from the electrical and mechanical area. All the mechanisms are in oil bath so they are more resistant to wear and tear and consequently long-lasting.

Technical features - THERMOFORMING SECTION
Material feeding and blister lidding
The reels of forming material are arranged in a compartment at the back of the machine, but can also be installed at the front of the machine, if requested. There are transparent guards to protect them against dust. Reel unwinding is automatic, servo-driven and stops when the film runs out. A splicing table with automatic web grip vacuum keeps the film in the right position and allows the technician to quickly join the new reel with the old one.

The lidding reel (maximum diameter 300mm) is located at the front of the machine and this too has an automatic splicing table to make reel replacement much easier. 

Pre-heating and forming
The thermoforming station is arranged at the back of the machine so that the overall footprint is more compact and the technician is better protected from the forming material fumes. The forming material loading area and the machine feeding station are therefore completely separate, thus reducing the area with modified atmosphere and minimizing costs.
The material is formed in three different ways: by compressed air for PVC, PVDC and ACLAR, by air and plug assist for difficult-to-shape plastic and by a purely mechanical solution of forming dies for aluminum.
A servo-driven transfer roller positions the forming material correctly for the infeed stroke, which is adjusted automatically without the use of tools. The servo-driven heating plates open automatically if the machine stops so as not to strain the film.
