Description

The invention relates to a saw-wheel installation for the manufacture of wood fuel in small pieces, in which the cutting line is used for sawing, and for reciprocating a reciprocating moving trench. In the proposed installation, an automatic device was used to periodically feed workpieces under the saw for a certain length, consisting of two spring stops, moved at the required moments by means of a lever system and a toothed rack. The lever system and the rack bar, in turn, are driven by a rod interacting with a latch and focusing on the blade of the final saw. In FIG. 1 is a front view of the installation; FIG. 2 - the same in bo- coking; FIG. 3 - top view; FIG. 4 is a side view of a device for feeding workpieces after sawing for splitting; FIG. 5 - the same rear view; FIG. 6 - the same top view; FIG. 7 is a side view of a splitting tool; FIG. 8 - the same front view; FIG. 9 - the same top view.

The Matniki saw / proposed installation (Fig. 1-3) is mounted on the shoulder 2,

equipped with a load 4 and lifted or lowered above the workpiece by rotating about axis 3 with the help of handle 5. The saw / is driven from the motor via pulley 6 and gears 7, 8, 9 to 10. Under table 1 there is a table 11, which is put aside to be sawed; beside table 11 there is a table 12 on which sawn billets are transferred for splitting.

The block of wood to be sawn is clamped on the table P (Figs 1-6) between the rear stop / 5 and the front stop 13, equipped with a spring 14 and capable of: moving in the vertical direction. An anvil 75 is associated with ratchet spring rails 15 placed in the guide 16 of the table 7 / and under the influence of two pairs of dogs 17 and 26. The dogs 17 are stop and serve to prevent the backtracking of the rails 15 when feeding the workpiece; the dogs 26 serve to move the rails 15 in order to feed the workpiece after it is sawn, for which they are associated with a spring moving frame 24. The frame 24 is placed in the guides 25 and moves in them when the rotary rod 22 is periodically exposed to it

The rod 22 is articulated by a lever system with a rod 19 carrying a hooked end / R, which can engage with a latch 20 on the shoulder 2 of the saw 7, Dogs 17 and 26 are also provided with pins 30 and 31 connected by cross-pieces 29, 29, which, in turn , are connected by rods 29 to the pedal 28.

The cutting of the saw / chock from the table 11 plate 72 using the described tool is carried out as follows. After the end of each cut, the shoulder 2 of the saw 7 under the action of the load 4 rises upwards, and the latch 20 of the shoulder 2 grips the hooked end 19 of the rod 19 and does not fall behind it upwards. During this movement of the rod 19, the associated rod 22 on one side retracts the stop 13 to move the workpiece forward, and on the other hand acts on the frame 24, moving it along with the rack 15. The rail 75, in turn, moves the stop 75 and thereby moves the cut part 22 of the workpiece to the table 12, and the workpiece itself delivers for a new cut. When the shoulder 2 of the saw 7 approaches the extreme upper position, the stop 27 placed on the shoulder pushes the end 7P of the 7P rod from the latch 20 of the shoulder 2, as a result of which the rod 79 is lowered, returning the rod 22 to the non-operating position. In this case, the abutment 13 under the action of the spring 14 rises up to hold the workpiece, and the frame 24 and the rail 75 stop the feed movement; dog 77 at the same time keeps rail 75 from moving it backwards. A new cut is then made and the process described is repeated until the final cutting of the whole block of material is completed.

After the entire billet has been cut and all its parts are transferred from table 77 to table 12, pedal 28 pushes 7 and 26 rise above rails 15 and released rails 75 under the action of spring 27 return with stops 75 to initial position .I

The chock 22 cut off from the workpiece, as mentioned above, moves to the table 72 as it moves the rails 75, and the rod 22 acts upon the chock 22 during its described movements

from the bottom and turns it onto table 72 where the chopping is done. On the table 72, there are slides 5 (FIGS. 7-9) fitted with a turning disk 43 edged from four sides and ratchet spring rails 44 interacting with resistant dog 48 and moving dogs 45. The ends of the dogs 45 and 48 are connected by flexible rods with the end levers 50-50 hinged on the shoulder of the levers 46, connected by their ends with dogs 45 and connected with earrings with a frame 41 pressed to the choking chop. End 50 rylag (articulated by a flexible pull 57 with a spring frame 56 interacting with the stopper 57 on axis 32 of disk 57. Axis 32 in addition to the disk 37, the flywheel 35 is equipped with a crank 34 with a connecting rod 35, which is connected with the striker 36. Axis 32 is driven by the clutch locking 57 of the disk 37 with the flywheel 33, which is in turn rotated by means of a flexible transmission from the main shaft of the installation. Axis 32 also carries a fist 38, which presses a chock against a table 72, for the purpose of its clamping, a frame 41.

When the chock 22 enters from the table 77 on the slide 43 of the table 72, it is appropriately set so that it can be cracked on the disk 43 of the slide 43. Before splitting, the fist 38, mounted on the axis 32, lowers onto the chock 22 a frame 4, which clamps the chock. By the time of clamping, the crank 34 with the connecting rod 35 approaches its highest position and as the axle 32 is further rotated, the striker 35 strikes the chock, breaking off a piece of it. Then the cam 38, when the axle 32 is subsequently rotated, releases the frame 41, which, having been lifted under the action of the spring 42, in turn releases the chock. When the frame 41 is lifted, the lever 46 is turned and the dog 45 moves the slide 43, feeding the chock under the next strike of the striker to break away the next piece, and the slide 43 is locked by the dogs 48 in the proper position. By the end of the delivery, the fist 38 with the frame .7 is again lowered onto the chock, the firing pin 36 cleaves the new part from the chock and the described process repeats until the whole choke is split.

When the entire chock is split, the lever 49, fitted with a adjustable load 49 and placed at the end of the rails 44, turns and hits the end 50 of the lever 50-50. In this case, the end 50 of the lever rises and pulls the dogs 45 and 48 connected to it from the rails 44, as a result of which the rails return together with the sled and chock to their original position. At the same time, the end 50 of the lever 50-50 retracts the spring frame 56, which moves the stopper 57, by disconnecting the flywheel 38 from the disk 37, through the pull out of the disc 37, resulting in the rotation of the axis 32 and the movement of the cam 38, the frame 4J of the striker 36.

When the sled 43 and the rails 44 return to their original position, one of the pins 54 of the rotary disk 43 of the sled 4 on which the chock rests meets a fixed stop 55, as a result of which the disk 43 rotates about an axis 53 through an angle of not more than 90 °. After that, the lever 59 releases the frame 56, the stopper 57 of which includes the rotation of the axis 32, and the slide 43 together with the turned chock is fed again to the striker 36, and the chock splits into smaller pieces. The rotation of the disk 43, together with the chock, is limited to an angle of not more than 90 ° by the spring 58, which interacts with the edged parts of the disk 43.

The subject matter of the invention.
