In the brewery business returned bottles need to be separated according to colour before being washed and ready for production. When moving their sorting station for returned 33 cl glass bottles to a new building, Spendrups had the opportunity of designing their own tailor made solution. Spendrups wanted to achieve a sorting station that was taking up less floor space than the one they were replacing, as glass bottles are in less demand. For working out the specific robotic solution in detail, Spendrups enlisted Kopparbergs Robotteknik who has successfully designed other robot cells for Spendrups.
From incoming pallets filled with returned glass bottles, still in their red plastic crates, the large MPL500 robot picks up one layer at a time. The robot deposits these crates on a conveyor and makes use of the ingenious dual function of the Air Grip gripper to immediately pick up the bottles from the crates and place them on another conveyor. Thus separating bottles from crates.
A sorting machine then separates the browns and greens from the translucent bottles. These bottles will at the twin robot station, on different conveyors, where the two MPL300 robots also use the Air Grip tool to place bottles into crates, and filled crates on pallets to be transported for washing.
The robotic de-palletising and colour separating cell is able to handle 30.000 bottles per hour.
It generally operates on a day shift, but is capable of running on a two shift when the demand is high. Equally important is the fact that the working environment has been improved with a reduced noise level, more user friendly equipment and an increased safety.
