GREEN AUTOMATION
Machines, assembly lines and also standard modules

Small and medium sized parts with high-speed assembly. This is Cosberg philosophy. Cosberg manufactures in-line machines and fully integrated assembly systems for the high-speed automatic assembly of small and medium sized

parts (up to 300 x 300 mm and up to 10 kg in weight), mainly for electro-mechanic, automotive, household appliances and furniture fittings industries.

The proposals range from rotary table machines to in-lines with free pallets system, robotised plants, leak test and seal control systems.

Cosberg also supplies independent automation modules: electromagnetic and resonant (piezo) vibrating feeders, both circular and linear; hoppers and conveyor belts; standard units for supplying nuts and rivets; pick and place arms;

manual screw-driving units with their own screw supply; slides and screw-driving units with one or more spindles for screws, nuts and studs; slides and insertion units with one or more spindles for rivets or pins.

Modules development has never stopped and new modules are still being created in order to be always superior in comparison with the competitors (Cosberg has deposited a score of

patents).

Cosberg is based in Terno d‘Isola in the province of Bergamo and has facilities in Flero (Brescia), where test and inspection systems are manufactured, and in Pontassieve (Florence), where bowl feeders are tooled and customized.

Cosberg exports to Germany, Austria, Finland, Spain, France, Slovenia, Greece, Morocco, Turkey, South Africa, Brazil and South America. It has reinforced its position on the French market with a branch at Bourgoin Jallieu – Cosberg-France –on the South American market with its branch in Saõ Paulo – Cosberg Sul America- and Slovenia, that is our “door” towards East market.

Cosberg mainly supplies three industries: automotive (specialising in brakes assembly and

tightening studs), electro-mechanic (especially plugs, switches, sockets) and accessories for

furniture (hinges, drawer guides) but it is also involved in other fields (e. g. it supplies screwing units and special machines to spectacle manufacturers). Cosberg has specialized in the pneumatic high-speed in-line machines with loose pallets with hourly output of 4,000–5,000 parts for furniture hinges. Pneumatically operated rotary table machines have also been built for this industry with an hourly output of 13,000 to 14,000 parts. The use of mechatronic modules increased our assembly  machines performances. Cosberg designs and engineers most of the main units in order to have full control of all the elements that contribute to operating reliability.

The modules are standardized and this enables functional parts and sub-units to be sold, such as the screw-driving unit and the manipulators.

 

 

Energy saving with electroresonance (piezo) feeders- Moxmec

The Cosberg green discovery is a worldwide patent system applied to its feeders: electroresonant bases (ADER and ADERAF).

They are designed for vibration feeding of light pieces of small dimensions and are very stable and accurate and are not subject to interference from the external environment. They save considerable energy (consume up to thirty times less energy than electromagnetic systems). The optimum operating frequency can easily be set by the adjuster. The vibrating base can easily be set, even whilst the cup is being processed and customised. Operations can be resumed in just a few minutes, so these feeders are ideal for quick production changeovers. The circular electroresonant feeders comprise a vibrating base with a 100 mm to 500 mm diameter that can be equipped with different types of conical, cylindrical and spiral cups with diameters ranging  from 110 mm to 800 mm. The parts enter the cups in bulk and ascend the tracks, where they are sorted until they reach the outfeeds.

The feeders are considered “the heart” of the assembling machine. With the application of

the electroresonance vibrators, Cosberg could realize an increase of efficiency by 10–15 %to the whole assembly plant.

This applies especially to linear electroresonant feeders. The most important factors are reliability and energy saving. Although the feeders are more expensive than electromagnetic

ones, careful costing shows that the difference is amply justified.
