Fully automatic respooling for precise and flexible spool set-up

Reliable, fast and precise wire laying technology has been a major focus of Swedish wire machinery manufacturer Lämneå Bruk AB in recent years. All of the company’s concepts are individual and designed according to customers’ specific requirements. Lämneå Bruk offers a range of respoolers, fromsemi-automatic for SAWwire toheavy machinery that can handle spools of up to 100kg. One of the company’s flagships is the fully automatic Precision LayerWinder, now in its second generation, which combines speed, precise wire laying to a 100 th of a millimetre, user-friendliness and high safety standards.

The spool changes are fully automatic with servo-drive motor-operated tooling for continuous production at speeds of up to 35m/sec. For a smooth and efficient process, the fastening of the finishing end is also made by servo motors. The servo motor brand is customisable, and customers can choose between Siemens, Lenze and Allen Bradley. To add to the flexibility, the spool supply magazine can handle different types of spools such as wire baskets, plastic and fibre spools without adjustment. In response to customer demand, the fully automatic Precision Layer Winder is now also available for smaller 5kg spools.

Lämneå Bruk has also developed a packaging robot for the fully automatic Precision Layer Winder. The total weight of the finished spools is checked; if there are any discrepancies, the robot puts the spool aside to be checked by staff and continues with the next spool for an uninterrupted process. If everything is in accordance with the quality standards, the automatic packaging robot moves the finished spools onto pallets for labelling and final packaging for shipping.
