The demand for high flexibility with small lot sizes rises constantly in industrial manufacturing of furniture.There are new demands, especially for cutting-to-size. In the future, it will be essential that cut-to-size plants guarantee speedy cycle times and optimized material utilisation when processing small lot sizes. 3rd phase cuts are an essential component to guarantee this.
Up to now it was not possible to produce fully automated 3rd phase cuts on a cut-to-size plant. Schelling has achieved just this with the NEW revolutionary development of the 3rd phase cut router that allows 3rd phase cuts with a perfect cut quality and highest size tolerances.
Functional description
The 3rd phase cut-router is used in connection with a conventional cut-to-size angular plant. Single boards are cut into strips on the rip-cut saw and then moved to the cross-cut area. Before the 3rd phase cut application, the strips are clamped and moved towards the cross-cut saw by the programmed feeder carriage. Now the trim cut on the cross-cut saw is made and the part aligned against the cross-cut-fence. The programmed feeder carriage then pushes the strips through the stationary router for 3rd phase cuts. During the milling the specially designed strip aligner with press-roller constantly pushes against the material and guarantees absolute accurate sizing.The required 3rd phase cut width is achievable with the moveable frequency controlled drive router. The router is raised to the working area by a servo motor.A separate extraction system for the router provides a perfect, dust free surface. The extraction hood is lowered on to the material during the milling progress. The integrated rollers in the extraction hood hold the material down against the roller table underneath.
Once the required 3rd phase cut depth has been milled, the router lowers and the feeder positions the strip for the cut-to-size process. For a board thickness of up to 25 mm the router tool has a diameter of 10 mm.The saw blade of the cross-cut saw is 5.4 mm and therefore we can guarantee that with only one cut cycle, the parts are produced with a perfectly cut edge.
The trim waste is removed via an adjustable waste flap into a waste bin. This waste bin tilts and turns 90° so that trim waste is disposed into the waste conveyor of the cross-cut saw.
With this system, Schelling offers a complete system that is logisticaly supported by Schelling's Optimisation Software HPO. Maximum output, perfect tecnical solution in highest quality, all out of one hand. This is what this new innovation from Schelling stands for.
