Mitaca and MG2 are two standout manufacturers in their own fields of expertise: capsule systems for espresso and hot beverages for Mitaca, automatic dosing and packaging machines for pharmaceutical products for MG2. Two apparently distant operators have met and developed a successful cooperation.

 

The protagonists of the story

MG2 is based in Pianoro, in the province of Bologna, in the heart of the Italian Packaging Valley; the company employs approximately 170 people, and counts on more than 45 years of highly qualified experience in the development of proposals made to measure, in order to meet the requirements of its customers (mainly multinational companies and subcontractors of the pharmaceutical sector). Mitaca is based near Milan, the epicentre of Italy’s most developed industrial district, and has been working for years to offer an excellent coffee and the best products for its preparation to the most exigent consumers in offices, companies and public spaces. In fact, the Lombard firm aims to become a leader in the Office Coffee Service and Automatic Distribution, thanks to the innovation and quality of its products and services. Mitaca espresso machines are the result of careful design, offering innovative solutions to simplify their use and guarantee an espresso that is always excellent. The I-Espresso System and Mitaca Professional System capsules employ an exclusive, patented technology, which guarantees the capsule opening solely by water pressure.

 

Mitaca’s production lines

Mitaca decided to rely on MG2 to cover the increasing requirements of its production line for coffee capsules. Each line starts with coffee beans and ends with the final product, palletized and ready for shipping. A first machine grinds the coffee, doses it into the capsules and closes them, thus making the product which the user will insert into the dispenser to make the relevant drink. Then, depending on the kind of final user, each capsule is individually packed in a flowpack with protective atmosphere to preserve its freshness and aroma, or else packed in multi-capsule bags. Both bags and individual flowpacks are finally packed into cardboard boxes. To carry out this final phase, MG2 offered a very simple solution to pack the bags, by using a horizontal case packer Mod. GSL10. For the final packaging of flowpacks, the Bolognese company designed and carried out a custom made solution which employs two vertical case packers Mod. GTL30.

                                                                                        

MG2’s solution

For this application, the basic machine which handles the case (opening, conveying and closing it by hot glue) was combined with a specially designed infeed system. In fact, it was necessary to solve some specific problems such as the high production speed (reaching up to 500 flowpacks per minute), the impossibility of accumulation (as the flowpacks must not touch themselves during conveyance) and the need to work with a product flow which is characterized by inconstant spacing and orientation. MG2 therefore adopted a series of belts with different speeds to stabilize the flowpacks feed, combined with a counting system with photoelectric sensors and a preload hopper equipped with opening and closing system driven by servomotors.


 

The results

GTL30 was warmly welcomed by Mitaca thanks to its reduced footprint and ease of operation, enabling to set the number of products and case size from the operator panel. Moreover, the machine also proved particularly reliable in both counting and delicate handling of the product during the packaging phase.
