Abstract

The invention relates to woodworking machinery and can be used in the woodworking industry. The purpose of the invention is to simplify the design of the line and increase its performance. The line includes a band saw machine 1, having a frame 2, drive and tension pulleys with a band saw and a feed mechanism 6 with a table 7. A beam 9 with face clamping cams 10 is mounted on the table 7. The feed mechanism 6 is mounted on the drive rod 11. The line is equipped with a cutting a device containing a fixed matrix 13 with longitudinal and transverse blades, forming cells by the size of the resulting sawn timber, in which spring-loaded pushers are located and a driving punch 17 with a working surface 18 made of elastic material la The line includes an orientation device containing a double-arm lever with a shelf 23 and a spring 24 and a fixed wall 22. The beam 9 with the front cams 10 moved moves the timber 28 towards the stop wall 26, after which the timber 10 is clamped over the edge of the timber. The feed mechanism 6 with the wood 28 is moved down, sawing off the slab, which, falling down, falls on the shelf 23 of the lever 21. With further lowering of the feed mechanism, the spring-loaded lever arm 21 contacts the punch 17, turning the lever 21 counterclockwise. The slab feeds into the receiving conveyor 27. In a similar way, the board is sawed off, only it falls on the raised stopper 19. After lifting the feed mechanism 6, the punch makes a move from right to left, pressing the unedged board to the knives of the matrix 13. The board is cut into finished sawing products. The line has a simple design and allows to increase productivity in the manufacture of sawn timber. 6 Il.

Description

The dbiMH cams 10 moves the timber 28 to the stop wall 26, after which the timber is clamped by the cams 10 by the edge of the timber of the timber. MB. The feed unit 6 with wood 28 is moved down, sawing off the slab, which falls down onto shelf 23 of lever 21. With further lowering of the gear mechanism, the spring-loaded lever arm 21 contacts the punch 17, turning the lever 21 counter-clockwise

ki The slab falls onto the receiving conveyor 27. In a similar way, the board is sawed off, only it hits the raised stop 19. After lifting the feed mechanism 6, the punch makes a move from right to left, pressing the unedged board to the knives of the matrix 13. The board is cut into finished sawing products. The line has a simple design and allows to increase productivity in the manufacture of sawn timber. 6 Il.

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

The purpose of the invention is to simplify the design and increase productivity.

Figure 1 shows a line for the manufacture of short sawn timber, side view; 2 - the same, top view; - FIG. 3 - main mechanisms, side view; in Fig. A, view A in Fig. 1; on fig.Z - section BB in figure 4; figure 6 - section bb In figure 4.

The lines for the manufacture of short saw sawmills include a band-sawing machine 1, having a base 2, a driven 3, and a pulling 4 SCIDERS with a band saw 5, a feed mechanism 6 with CTOJIOM 7. On the table 7 in the guides 8 a beam 9 is mounted with end cams 10 The feed mechanism 6 is mounted on a drive rod 11 mounted in vertical guides 12.

The line is equipped with a cutting device containing a fixed matrix 13 with longitudinal 14 and transverse 15 knives, forming cells according to the size of the sawn products in which spring-loaded ejector I6 and a driving punch 17 with an elastic surface 18 are placed. The cutting device has a limiter 19 with a drive cylinder 20.

The line is equipped with a device orientation, containing two shoulders lever 21, hinged on the table 7 on the outside of the working branch

band saw 5, and a fixed wall 22, placed on the inner side of the working branch. One arm of the lever 21 is provided with a shelf 23 located below the band saw.5, and the other plep is equipped with a spring 24. The line is also equipped with a feed conveyor 25, an anvil wall 26 and a receiving conveyor 27, in addition, the timber 28 is shown.

Lini works as follows.

The conveyor 25 delivers the wood 28 on the table 7 mechanism. The beam 9 with the butt cams 10 moved apart moves the timber 28 to the stop wall 26. When the timber surface reaches the surface of the stop wall 26, the timber is clamped by the jaws-10 beyond the edges of the timber ends. After this, the feed mechanism 6 with the timber 28 is moved down by bar 11, sawing off the croaker, which, falling down, falls on the shelf 23 of the lever 21. Next, lowering down, the croaker slides along the surface of the fixed wall 22. The spring-loaded lever arm

21 contacts punch 1 by turning lever 21 counterclockwise. Shelf 23 moves away from the wall.

22 and the slab falls onto the receiving conveyor 27. At the same time, the stopper 19 is in the tilted position. The feed mechanism 6 is returned to its original position. Beam 9 presses the timber against the wall 26 and the cutting process is repeated. Only now the board sawn off is not handled and falls onto the raised stopper 19. After lifting the feed mechanism 6 to the initial position, turn on the knob. Z
