Want blisters fast Integra 320’s pitch control system, together with Marchesini’s new cartoning section and carton opening and product insertion system, is able to boost production performance up to 320 blisters and more than 260 cartons a minute.
Want blisters with a small footprint? Because of the integration of the blister thermoforming and carton packaging phases in a compact line, the new system has a very small footprint.
Want to know how Marchesini does it?
Marchesini three-axes Robocombi with sucker pick-up head, connects the two stations and minimises size change-over operations. The units are no longer made up of several single parts but of integrated blocks, which are replaced in just one go. The forming station, operated by a servomotor, is installed at the back of the machine. This makes the layout more compact with the product infeed zone separate. The material pull and machine pitch can be adjusted directly from the display. The product infeed unit is easily fitted in place without having to use tools. The parts have quick-lock couplings to make replacement and assembly work fast and accurate. The machine is supplied pre-arranged to fit a number of combined infeed units to ease product changeover. All parts are designed so that the product flows easily and smoothly. Because each step is made with positive motion, obstructions or blind spots are avoided. The dust extraction system with separation of small chips has plenty of suction points distributed in a capillary manner along the machine. The flat and continuous-motion sealing station follows the film so that it can be sealed even at low temperatures. The combined intermittent and tracking movement gives the two materials more time to seal at a constant pressure along the full surface of the blister. If the machine stops the plates open, thus safeguarding the material between them. Once the blister has been cut, it is picked up and placed on the outlet belt without any other transfer movements before it is picked up by the Robocombi. This robot picks up the product, stacks it correctly, and places it directly into the buckets of the carton packager. The perforation and coding station has separate bins for accurate waste management. The carton packaging section features a new pick-up and erection system for cartons with split movement that picks up and erects more than 260 cartons/min with positive motion. The system is completely mechanical and features an oil bath to ensure a longer service life and less maintenance. The carton magazine is installed in a practical position for loading and away from the zone where the product runs. Any dust created in the magazine falls to the ground and not onto the moving components. The carton conveyance system has also been improved. Two pushing and contrasting teeth guarantee maximum conveyance precision. Cartons maintain integrity and stability, even at high speeds. The product insertion unit has pushers and is equipped with counter-pushers and independent drives. All the units are driven by brushless servomotors so that each station is independent, increasing flexibility even though working at high speeds. The line’s balcony design simplifies cleaning and preserves the integrity of the products. Individual processes are clearly visible through its larger transparent guards. The whole setup complies with GMP standards.
