Definitions
- the present invention relates to a sawing device as defined in the preamble of claim 1.
- the slowness of sawing is a particularly bad problem in industries where there is a need for large quantities of relatively short fixed-length timber pieces, for example in furniture industry, prefabricated building industry and parquet industry.
- the object of the invention is to eliminate the drawbacks referred to above.
- a specific object of the invention is to produce a new type of sawing device that enables long timber to be accurately cut into fixed- length pieces in a continuous process as fast as possible.
- the sawing device of the invention comprises a conveyor for conveying the timber to be sawn and blades for cutting the timber at desired points, said blades being rotated by a first power unit and disposed in a transverse position relative to the lengthways direction of the timber to be sawn.
- the sawing device comprises a rotatable frame rotated by a second power unit and supporting the blades, of which there are preferably at least two.
- the sawing device comprises a third power unit and, in the rotatable frame, guide rails along which the blades can be moved back and forth by means of the third power unit in the direction of the axles of the blades, i.e. in the longitudinal direction of the timber to be sawn.
- the rotatable frame preferably comprises blade axles disposed at the same distance from the axle of the rotatable frame and parallel to it.
- the blades are preferably supported by separate blade holders movable along guide bars parallel to the axles of the blades.
- the back-and- forth movement of the blades in the direction of their axles is preferably implemented using a motion chain, which is connected to the blade holders and can be moved back and forth.
- none of the power units is mounted on the rotatable frame, but the first, second and third power units are mounted outsi- de the rotatable frame and coupled via concentric axles to the rotatable frame.
- the third power unit which moves the blades back and forth in the direction of the axles, is preferably arranged to work in synchronism with the conveyor that moves the timber to be sawn, in such manner that the velocity of motion of the sawing blade in the direction of its axle is always the same as the velocity of the timber moving on the conveyor.
- the sawing device of the invention preferably has two sawing blades mounted in the rotatable frame, but the number of blades can also be considerably larger, in which a lower speed of rotation of the rotatable frame will result in the same sawing efficiency.
- the sawing device of the invention has significant advantages as compared with prior art.
- the pro- duction of a large number of fixed-size pieces of wood is not an intermittent but a continuous and smooth process in which the timber to be processed is moving at a constant speed throughout the sawing process .
- the sawing de- vice can cut three fixed-size pieces of 60 cm per second, and even more.
- the sawing device of the invention presented in the drawing comprises a suitable conveyor 1 together with its power units 18 for moving an object to be sawn 19 in its lengthways direction.
- the sawing de- vice comprises a rotatable frame 6, which is supported by its axle 12, which in turn is supported on the frame 20 of the sawing device.
- a second power unit 5 is arranged to rotate the rotatable frame 6 about its axle 12.
- Mounted between the two end pieces of the rotatable frame 6 and parallel to the axle 12 are a first pair of guide bars 8 and a second pair of guide bars 9 as well as a first blade axle 10 and a second blade axle 11.
- Supported on the first guide bars 8 and the first blade axle 10 is a first blade holder 13, which carries a first blade 3.
- a sec- ond blade holder 14 carrying a second blade 4 is supported on the second blade axle 11 and the second guide bars 9.
- the blade axles 10 and 11 are coupled via power transmission belts 21 to an axle 16 concentric with the axle 12 of the rotatable frame 6 and mounted inside it and coupled to a first power unit 2, which is mounted on the frame 20, to rotate the blades 3 and 4.
- the blade holders 13 and 14 supported on the guide bars 8 and 9 are attached to a motion chain 15, which moves back and forth on chain wheels 15.
- the chain wheels are rotated back and forth by means of a third power unit 7, which is coupled to the chain wheels via an axle 17 concentric with the axle of the rotatable frame and mounted inside it .
- the sawing device presented in the drawings works as follows.
- the first power unit 2 rotates the saw blades 3 and 4 while the second power unit 5 rotates the rotatable frame 6 at a suitable speed.
- the third power unit 7 moves the blade holders 13 and 14 and the sawing blades 3 and 4 rotating with these back and forth in the direction of motion of the object to be sawn so that when one of the blade holders is moving forward, the other one is moving backward.
- the sawing blade touches the moving object to be sawn while itself moving at the speed of the object in the same direction and, after cutting the object, moves aside and returns back to the starting position of a new sawing operation.
- the other saw blade performs corresponding sawing and returning actions on the opposite side of the common rotation axis of the saw blades .
- the synchronisation of the motors in the sawing device and of their movements can be implemented using electronic or mechanical means known in themselves.
- the blades 3 and 4 are preferably rotated continuously by means of the first power unit 2, but the rotation of the rotatable frame 6 by the second power unit 5 and the back-and- forth motion of the blades produced by the third power unit 7 may be either continuous or intermittent according to need, depending e.g. on the quality of the object to be sawn, on the blades being used, the length of the pieces to be cut, and so on.
