Assembly line for VELUX

Delivery period: August 2013

The client: SIG Sonneborn – VELUX
The “SIG Sonneborn Bauzubehör Industriegesellschaft mbH” manufactures the high-quality VELUX roof windows on a total area of approx. 170,000 sqm with a very modern machine park. As the German production company of the VELUX Group we have made an excellent name for ourselves. We secure long-term success with exemplary production technology, high productivity and constant quality improvement.

Customer requirement – Ergonomically designed production line for the most automated possible assembly of window frames of various dimensions

The customer’s task included challenges both with regard to the construction of the conveyor line itself and the commissioning. Working on the assembly line should not only meet ergonomic requirements, but also offer largely automated processes for standard dimensions of max. 2,000 x 1,600 mm (LxW) as well as all the necessary manual procedures for the assembly of individual and special frames. In addition, the workpieces should be tilted, turned and positioned exactly as required.

The latter also referred to the transfer point to the continuing production line. The new assembly line was to be integrated into the existing conveyor system. After an extremely short delivery time of eight weeks, all installation and docking measures had to be carried out outside of operating hours in order not to impair the client’s production flow.

Our solution

Two feeding stations and precise merging before transfer to another production line. The window frames in (different) standard dimensions are transported to the next work step via a buffer roller conveyor.

There the work surface is automatically adjusted to the correct height by means of servo motors. A drilling device attached to the rear of the unit drills the pre-set holes and milled out areas.

Afterwards the processed frames are carefully tilted into the horizontal position with the help of a pneumatic cylinder and transported on a driven roller conveyor in this position. A belt conveyor moves the frames to the removal point.

A second feeding station is used for manual processing of single frames and those with special dimensions.

After assembly, a pneumatically driven tilting station ensures gentle preparation for further horizontal transport via a roller conveyor with chain diverter. Below the belt conveyor in front of the unloading station is a driven turning station which can realign the manually mounted frames by up to 270° in the horizontal direction in order to prepare them in the correct position at the unloading station for removal.

The drives are controlled by PLC systems and frequency converters. Of course, our installation also includes all relevant safety devices, such as emergency stop switches and safety fences. As usual, our experienced specialists succeeded in putting the new assembly line into trouble-free operation within the agreed period and had it accepted by the customer.
