Production Line for Solid Wood Components in Furniture Manufacturing



The automatically linked timber processing line consists of a buffer cross chain conveyor (1), an AB920 automatic infeed system (2), a CGL rip saw (3) and a cross chain conveyor (4). Subsequently there are up to three marking stations (5), measuring stations (6), C11 cross-cut stations (7) and a sorting system (8). The cross-cut lines are individually controlled via the operator terminals (9) on the MAXI 6 controls.

The ripped workpieces are further processed by two cross-cut lines type C11_MKL. A third cross-cut line can be retrofitted.

At the end of last year Paul delivered an automatically linked timber processing line consisting of a CGL rip saw with an AB920 automatic infeed system as well as two cross-cut systems type C11_MKL including sorting equipment. The line will be used at the company Zhucheng based near Tomsk (Russia) which is producing solid wood components, mainly from Russian Birch, that are finally ending up as furniture on the shelves.

The mainly dried and waney-edged workpieces with a length of up to 4.2 meters are transferred onto the buffer cross chain conveyor. While the material is singulated, the operator can carry out quality marking by means of crayon marks to increase the added value as well as the yield together with the optimizing software. Numerous triangulation measuring heads are detecting the geometry of the workpieces in order to obtain very good measuring and optimizing results, even with difficult workpieces.

The climb-cutting rip saw type CGL is edging the boards and at the same time variably ripping them into one to four strips, depending on the cutting list and optimizing result. The excellent width tolerance of less than 0.5 mm meets the high demands in furniture manufacturing. After the ripping operation the workpieces are fed to the cross-cut lines.

The timber processing line is completed by two cross-cut lines type C11_MKL with sorting equipment. For an increase in performance the customer can retrofit another cross-cut line. Up to two marking people per cross-cut line are working at the marking tables. A measuring station detects the length as well as the marked knots and features and transfers their positions to the MAXI 6 control. An intelligent software algorithm calculates the optimal cross-cutting result. Depending on the marking of the timer features, the quality, i.e. value optimization determines the maximum added value and timber yield. The preset lengths and finger jointing lengths produced are sorted in a fully automatic manner. The offcuts produced by the rip system are falling onto a conveyor belt at the end of the cross chain conveyor.
