Description

The invention relates to the forest industry and can be used to open and sort round timber. A device for freezing lengths and dropping assortments containing a cutting table made in the form of separate turning sections with grooves 1 is known. A device for cutting logs on logs containing a mechanism for longitudinal movement of logs, a saw, a frame with a receiving table consisting of two pivotal sections through the drive of the pads, and stops made with the possibility of their rearrangement along the receiving table, as well as remote sorting and distribution mechanisms. The disadvantages of the known devices are the limited sorting range of sawn off assortments and the complexity of the design. The purpose of the invention is to expand the range of sorting sawn assortments and simplify the design of the device. The goal is achieved by the fact that the device is equipped with an auxiliary lever installed between the saw and the first section of the platform and mounted on the shaft of the second section of the platform, with part of the external sorting and distributing mechanisms installed on the side of the second section of the platform for sorting long logs, and sorting and distribution mechanisms are located under the first section of the platform for sorting short logs. FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; in fig. 5 is a view of B in FIG. one; in fig. 6 is a view of FIG. 3; FIG. 7 is a section d-d in fig. 6. A device for cutting round logs contains a mechanism 1 for longitudinal movement of logs, a saw 2 and a frame 3 with a receiving table. The receiving table consists of two sections-platforms 4 and 5, sequentially placed along the frame 3 with the possibility of rotation on the horizontal shafts 6 and 7, respectively. On one horizontal shaft with a section of the platform 5 auxiliary lever 8 is rigidly fixed, placed between the saw 2 and the first section of the platform 4. On the frame 3 of the device a block of stops is mounted in the form of levers 9 arranged along the receiving table, fixed in the bracket 11 and rotated in the vertex (the ticking plane around the axis. Fixing the 1kronschteyn 11 with the lever 9 in the desired position (along the receiving table) is carried out using a screw 12 and a figured bar 13, entering from the bottom into the groove. It also contains sorting and distributing mechanisms, made in the form of inclined trays or remote longitudinal conveyors. Under the first section-platform 4, four sorting trays 14 (according to the number of levers 9 above platform 4) are installed, between which are distributed through hydraulic cylinders hookers 15. These sorting trays are designed to receive and sort short cut sawn timber. Sorting trays 16 with a distributing gate 17 are installed on the side of the frame 3. These trays are intended for receiving and sorting long assortments. In the front part of the frame of the device, there is a hatch for dumping into it the pelts obtained during the process of facing the log, and short logs of length 0.5-0.6 m, sawn along the first stop 18. In the manhole there is a spindle 19, designed to open trays for pitting. or for assortments with a length of 0.5–0.6 m. The gate gate 19 is connected by means of a stop 18 and a pedal 20. The length ordering system includes a series of control knobs 21, each of which has a link with its block of 22 cams, which have move in the horizontal plane to some the magnitude of the one and the other, from the middle position. In the middle position, the cam block 22 and the control knob 21 are held by springs 23. Limit switches 24 are installed on both sides of the knob, which, when influenced by knob 21, control the position of the hooks 15 and 17. On the brackets 11, a spring-loaded latch 25 is fixed, having one end a roller 26 resting in the initial position at the bottom of the depression of the cam block 22. The other end of the latch 25 rests on the protrusion 27 on the hub of the lever 9, keeping the latter in the initial upper position. The device works as follows. Before starting work, the operator sets the levers 9 in position corresponding to the lengths of sawn timber. To do this, you need to unscrew the screws 12 so that the figure bar 13 comes out of the slots on the frame. Then the bracket 11 with the lever 9 is moved to the desired position and secured with the screw 12, while the bar 13 must fit into the groove on the frame. In the initial position, the levers 9 and -18 are in the upper position. Section sections 4 and 5 occupy a horizontal position. The operator turns on mechanism 1 and delivers the beam to the flange. The cut-off piece falls into the hatch. Visually assessing the log, the operator determines the length of the log to be sawn off and, accordingly, lowers the required stop. The length order is made by turning one of the knobs 21 to one side or the other, with the first two knobs on the saw side controlling the first four levers 9 and the section-pad 4; the third knob controls the remaining two levers 9 and the platform section 5. For example, if you need to order the length of the assortment corresponding to the installation of the first lever 9, you need to pull the first knob 21 to the left, then the first cam block 22 will also move to the left. One of the cams of the block will lift the roller 26 of the latch 25, the opposite end of which will come out of engagement with the protrusion 27 of the lever 9. The lever, under the action of its own weight, will fall and take a horizontal position. Moving the cam block to the left will not cause the second lever 9 to roll over, since its latch roller will roll along the bottom of the cavity. At the same time, when turning the knob 21, one of the limit switches 24 is turned on, which gives a command to install the gate 15 to the position opening the first tray from the operator and a preliminary command to turn the section-pad 4 clockwise (viewed from the side of the saw). After ordering the length, the operator using the feeder 1 delivers the log to the lowered lever 9, saws off the assortment and gives the executive command to rotate the section-pad 4. When it rotates, the front end of the sawn assortment tilts down and falls to the plane of the pin 15, which slides into tray. Section-pad 4, turning, raises the lowered lever 9, which engages with the latch 25 with its lug 27. When ordering lengths corresponding to the installation of the third and fourth lever 9, the process proceeds as described, but the section-platform 4 rotates in the opposite direction, and the opening of the trays is carried out by the second gate 15. When ordering the lengths corresponding to the installation of the fifth and sixth arms 9, the sawn off assortment is reset by the section 5, and the distribution in the trays is 16 by the gate 17. The This device has a simplified design and allows you to extend the sorting range of sawed assortments.
