Long screws, such as those used for roofing applications, tend to form large balls when placed in bulk bins. Several of our customers used to tip these bins on a table and then operators would untangle the screws using rakes or by hand, wearing special gloves. This process is extremely inefficient and results in poor working conditions.
Analysis
We analysed the size range of the roofing screws and how they form tight balls.
Line stations
We looked for a way to untangle the balls by machine, without human intervention. A rotating drum proved to be the best solution.
Special feature
We built a large, slowly rotating perforated drum to untangle the screws and feed them to the downstream line. The screws are aligned by a magnetic field for easy packing.

The untangling unit has proven to work very efficiently and reliably. We have used it in a number of projects, feeding either manual or automatic packing stations. This solution improves the efficiency of our operations and eliminates unpleasant and dangerous manual work.
