Description
The optimization saw KP 900 Easy Cut is designed for woodworking companies that process massive wood and put the maximum emphasis on the quality and yield of its production. The optimization saw KP 900 Easy Cut is used to cut out defects and optimize fixed lengths of slats in the production of glued prisms, joints, solid furniture parts, parquets, floor boards, decking, packaging, etc. The solid and robust construction of the optimization saw ensures accurate and fast cutting of wood. The feed device moves the cut material to the cut with great speed and positioning accuracy in the range of ± 0.3 mm (± 0.1 mm – options). The saw operator performs a visual evaluation of the piece and marks the places with errors with chalk. The material is placed on the loading table of the machine, where the length and marked defects are automatically read. This information is processed by the powerful NC control of the machine, which establishes the cutting plan of the inserted material. This is followed by an automatic start and moving of the material into the cut. The cut parts at the output of the optimization saw correspond to the requirements according to the marked defects and the specified fixed lengths of the material.

Basic device functions
Length optimization At the beginning, the lengths and number of pieces of the required assortment are entered into the parts list. We can then activate this data in the optimization program. It consists in the combination of individual selected lengths of the cut assortment in order to minimize waste. At the same time, the parts list monitors the amount of material being cut and stops work when the task is completed in the specified range. The saw automatically measures the length of the inserted material, so that several inserted lengths can be combined without the need for prior sorting. In the program, it is possible to set the desired length of cutting faces. On the rear belt conveyor there are positions for sorting lumber according to lengths. The individual punches are started when a part of the specified length is cut off. Sorting is done by slides into prepared boxes or on a side slide. The number of optimized lengths is unlimited.
Qualitative optimization
Optimization of lumber according to quality makes it possible to use the work cycle of the previous functions together with the possibility to mark lumber defects with chalk. The operator performs a visual evaluation of the piece and marks with fluorescent chalk the places with defects that must be cut out. The chalk contains a substance that is recorded by the saw’s control system. By crossing the stop above the cut material during the reverse movement, the current positions of the required cuts are read. The resulting parts in different lengths between the cut defects are automatically remeasured and cut to fixed lengths using the computer according to the optimized cutting scheme. The parts list determines the number of cut pieces of a given length. If the cut part does not meet the length of the smallest selected assortment, it goes to waste. On the rear belt conveyor there are positions for sorting lumber according to lengths. The individual punches are started when a part of the specified length is cut off. Sorting is done by slides into prepared boxes.
Statistics
A part of NC machine control is statistics, which register the number of regular meters cut, the number of quality parts and the quantity waste. Maybe so, for example Easily compare the quality of input wood from different suppliers, calculate the total volume of manufactured assortments (for identical widths), etc. The machine also records the actual working time, which can e.g. Use the head of the production department to check work performance. At the same time, it is possible to output to a printer and remotely manage the cutting via a PC from the office.
Production capacity optimization line
Production capacity is determined by the dimensions of the processed material, its quality and the manufactured assortments. For the calculation, the average loading speed data is 90 m/min. and the speed of one cycle of cutting approximately 0.5 seconds.
The performance of the saw is determined by the choice of two offered variants of the KP 900 Easy Cut saw:</ span>
(The values indicate performance from the practical use of saws by users of our machines, not theoretical machine time, which is often presented by foreign suppliers – intended for material 5m long, spruce, 30 x 90mm, 4 cuts per 1m)
S – standard – version with standard capacity – 500 – 600 m / 1 hour
Q – quick – version for maximum capacities – 800 – 900 m / 1 hour
Another possible expansion of the KP 900 Easy Cut saw
Rear sorting conveyor with the possibility of longitudinal sorting into several storage boxes. The system works on the principle of electronic measurement of lengths andsorting into boxes using punches. Possibility of cutting and subsequent sorting in up to 3 quality classes. Connection with an office PC – the possibility of checking the progress of the work, entering and editing values in the form of remote access. Smooth regulation of the speed of the saw motor in case of a variable change in the diameter of the saw blade and according to the requirement for the quality of the cut. Regulation is carried out by continuously adjusting the value via the control panel. Double-sided lateral pressure at the point of the cut (so-called finger pressure), which will increase the accuracy of the perpendicularity of the cut. Automatic supply of material to the saw. The possibility of connecting to a serial production line through the transverse feeding conveyor on the input table. Synchronization of feed and automatic start of the cutting cycle. The possibility of adding a number of feeding and handling elements in the form of driven and non-driven conveyors.
