Robo.Mec.® robotic bridge

This application has been specifically designed for large, high speed production systems.

It Its key priority is to feed packaging machines with suitable products only and to eliminate any manual intervention. In fact, operates with a 3D Vision System that selects and rejects imperfect products automatically. The system feeds high speed packaging machines and high capacity robotic units with suitable and fully packaged products only, so that any production stops or jams are avoided. The Robo.Mec.® bridges straddle the oven mesh and pick up the entire product group as it is fed in. A particularly high level of efficiency is achieved if the system is fitted with an automatic backup machine with no buffering systems that take up space and always require manual intervention.

This system guarantees the highest level of production efficiency without requiring any manual intervention in the most critical area of the production line.

The system is particularly suited to delicate products and special formats.

The Robo.Mec.® robotic bridge is a new patented development for transferring dry baked products like biscuits of all kinds, crackers and rusks in stacked packets, directly from the oven mesh to the packaging machine chain.

Compared to traditional collection and feeding lines, this system offers the benefit of eliminating all product handling (like channel infeed, transport, on-side stacking, portion forming etc.), which drastically reduces rejects and offers total hygiene.

A laser vision station located before the series of bridges (one for each packaging machine) serves as a quality control point and generates the pick-up and transfer signal. This machine stands out for its precise and sturdy mechanics that are common to all our machines, and features a control system specifically designed to offer a simple and user-friendly interface. The system can be used in any situation (so most of them) where the incoming product can be laid out in a clear geometrical pattern.

Operating principles

The Robo.Mec.® bridge structure straddles the oven mesh and is equipped with a twin-axis handling head that can access the entire surface covered by a group of incoming products and therefore the width of the mesh. The product is picked up by a series of suction cups mounted in pairs on the same arm and powered independently by pneumatic cylinders.

The head moves these units between the pick-up area on the mesh and the stack forming zone over the chain. Following a signal emitted by the vision station, the head moves towards the incoming group and the arms with their suction cups pick up a pair of adjacent products.

The head then lifts the product pairs and moves them over the chain, while also moving them into step. Having reached the chain, the head lowers and sets down the first product on a support table formed by two retractable plates over the chain.


Following this operation, the head moves sideways and sets down the second rusk on the first. The product is fed into the chain in the same position it was on the oven mesh. It then has to be rotated by 90°, which is why the suction cups are mounted on a rotating arm.

The chain is part of the bridge and the interface with the packaging machine chain consists of an overhead transfer mechanism that can also group the stacks to form multiple packs. The system can operate at 15 cycles per minute and for 44 rows, which is typical of a rusk line. So, a bridge can handle 660 pickups per minute, i.e. 330 packs of two per minute.

The system described is suitable for forming stacks of two in different grouping formats. Bridges for higher stacks can be set up using more than one pick-up arm. The Robo.Mec.® bridge consists of two axis control servomotors for raising and lowering the head, two for moving it forwards and backwards, two for recovering the step between the rows and one for the chain.
