Description

(54) UNIT FOR MACHINE FOR PILOPRODUCTION

one

The invention relates to woodworking machines and can be used in the lumber and woodworking industry.

A sawing machine is known, including a sawing mechanism, a remote conveyor and a feed mechanism 1.

Also known is an aggregate machine for the manufacture of sawn timber, including mechanisms for longitudinal incision and sawing, transverse and external conveyors, clamping, feed mechanism, drives and table 2.

A disadvantage of the known machines is their low productivity due to the large number of auxiliary operations.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that the machine is equipped with a transverse incision mechanism, an acceleration conveyor and a transfer conveyor containing two vertical chain loops with hinged cradles, and the feed mechanism is made in the form of

two track conveyors, the branches of which are located in the same horizontal plane, and the working branch of one of them is equipped with pressure rollers.

5At this, the sawing mechanism is made in the form of a horizontal band saw, and the crosscutting mechanism - in the form of a block of circular saws.

Moreover, the machine table has a platform with

10 with a vertical movement device.

FIG. 1 shows the proposed aggregate machine, a general view; in fig. 2 - the same, top view.

An aggregate machine for making sawing products 15 includes a longitudinal incision mechanism 1, a sawing mechanism 2, a transverse and an external conveyor 3 and 4, a clamp 5, a feed mechanism 6, drives 7 and 8, and a table 9.

The machine is also equipped with a mechanism 10

Claims (3)

20 of the transverse incision, an accelerator conveyor 11 and a transfer conveyor 12. The mechanisms and 10 longitudinal and transverse incisions are made in the form of a block of 13 circular saws separated by detachable rings 4 and bushings 15, thus obtaining products with different sizes in length and width. The sawing mechanism 2 is made in the form of a horizontal band saw 16.. The outboard conveyor 4 products in the form of plates 17 enters along an inclined tray 18. The clamp 5 is equipped with a comb 19 mounted on the rod of the hydraulic cylinder 20. Me. Feed mechanism 6 is made in two track conveyors 21 and 22, the branches of which are located in the same horizontal plane. The working branch of the conveyor 22 is provided with pressure rollers 23 with springs 24. Table 9 includes a receiving platform 25, a support surface 26 and an exhibition platform 27 of the transverse incision mechanism 10. The table is provided with a vertical movement device in the form of a hydraulic cylinder 28, which ensures adjustment to the required size over the thickness of the product. The accelerator conveyor And has stops 29 made in the form of rotary, spring-loaded. The transmitting conveyor 12 contains two vertical chain loops 30 and 31 on which the cradles 32 for transferring the material being cut 33 are hinged. The receiving platform 25 is equipped with a hydraulic cylinder 34 with pushers 35. The machine works as follows. The material to be sawn 33 is fed transversely by the reversible conveyor 3, from where it is removed by the cradle 32 and transferred by it when the conveyor 12 moves to the receiving platform 25. The cradle 32 as it goes down leaves the sawing material 33 at the platform 25, and pushers. 35 moves the material to be cut on the bearing surface 26. The pushers 3. return to their original position. The hydraulic cylinder 20 and the longitudinal incision mechanism 1 are turned on, the circular saws of which, when moving along the material being cut 33, perform longitudinal cuts in it at a depth equal to the thickness of the product being produced. This is achieved due to the fact that the circular saws, the longitudinal incision mechanism are raised above the supporting surface 26 by the thickness of the product. After the longitudinal cuts are made, the longitudinal incision mechanism switches on a switch, which gives a command to unclench the material being cut and turn on the hydraulic cylinder 34. The pushers 35 move the next material to be cut 33. on the supporting surface 26, which pushes the previous material onto the constantly-activated accelerator conveyor 11. The stops 29 supply the material to the feed mechanism 6. When the material is gripped by conveyors 21 to 22, the speed of which is lower than the speed of the accelerator conveyor 11, the stops 29, as a result of interaction with the material, turn and pass under the material, after which they return to their original position. Due to the presence of the accelerator conveyor and the performance of the conveyors 21 and 22 without individual grippers, a high density of their filling with material is ensured, regardless of its thickness. The feed mechanism moves the material to be sawn to the exhibition platform 27 and then to the cross-cutting mechanism 10 and the sawing mechanism 2, which separates the finished sawn-shaped timber 17 from the material. The boards 17 to the inclined chute 18 are fed to the remote conveyor .4. During processing, the material rests on the surface of the table 9 under the action of its own weight, so that the required product sizes are obtained automatically by pre-setting the table 9 to a certain height relative to the horizontal saw 16 and the block of 13 circular saws, the distance between which in the block is chosen in accordance with product sizes in length. After processing, the material is fed by the feed mechanism 6 to the cross conveyor 3, which is stopped to remove material from the cradles 32. The latter transfers the material to the receiving platform 25 again and the cycle repeats. In the process of processing on the wall, several brushes of processed materials are simultaneously registered. As the processing of the material is completed, a corresponding amount of new material is fed to the machine by the cross-chain conveyor 3. The use of the proposed machine allows to increase productivity in the manufacture of sawn timber. Claim 1.
