Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, backboards generated when sawing logs are sawn into plates using a bandsaw machine with a table in the first step, and are cut into tally or wood by the bandsaw machine or circular saw in the second step. I was looking at the width of products such as Nuki from the side.

That is, first, the first step is sawing into wide boards, and then the second step is sawing into wide boards.
After the selvage was done in the process, the side sight was reduced and sawing had to be done at least four times in the entire process, which had the disadvantage of significantly increasing costs.

In particular, since the first step involves sawing the back plate, which has irregular irregularities on both sides, into a plate material, there was no choice but to perform it in addition to the other steps.

The present invention aims to improve the above-mentioned drawbacks, and it is an object of the present invention to construct a side pillow saw by attaching a plurality of circular saws to a rotating shaft at intervals corresponding to the thickness of the product. A flat saw whose plate surface is orthogonal to the side pillow saw is disposed in the material movement path of the pillow saw,
This flat saw is composed of a pair of circular saws whose cutting paths are on the same plane, and a part of the outer periphery is lapped when viewed from the front and rear directions.
The split saw described in 11j is characterized in that a delivery roll is provided on the delivery side of the split saw from which a plurality of discs protrude from the outer circumferential surface to enter the respective sawing paths.

To explain the embodiment shown in one drawing below, l is a side pillow saw in which at least three circular saws 2, 3.2 are attached to a rotating shaft 4, and the intervals between them are proportional to the width 3 of the product. can walk out.

Further, on the cutting side of each of the circular saws 2, 3.2, a back splitting guide plate 5 is provided, and the back splitting guide plates 5.5 on both sides are synchronized with the circular saws 2.2 on both sides. You can walk away.

Furthermore, a pair of upper and lower feed rolls 8a, 8b are provided on the feed side of the circular saws 2, 3.2, and a portion corresponding to the back splitting guide plate 5, on the cutting side, has a small diameter. An upper intermediate roll similar to the upper and lower delivery rolls 7a and 7b is also provided at a portion corresponding to the rear part of the split guide plate 5. 8a and a lower intermediate roll 8b are pivotally supported, and the upper feed roll 6a
, the upper delivery roll 7a and the upper intermediate roll 8a are pivotally supported so as to be movable up and down.

Reference numeral 9 is a hand saw consisting of a circular saw whose plate surface is perpendicular to the plate surface of the circular saws 2. In the figure, a split disk 11.11 is supported by longitudinal shafts 12,12.

In the above-mentioned apparatus, when the back plate A is placed on the supply roll 13 from the left side in the drawing and fed, the thickness of the upper feed roll 6a, which is set slightly lower than the thickness of the back plate A (the other upper rolls are also The circular saw 2.3.2 rides on the back plate A and feeds it while clamping it in cooperation with the lower feed roll 6b, and the circular saw 2.3. As shown in the figure, the effective material a.

The waste material (a) is sawn into two pieces and the waste material (or remaining material) b on both sides is sawn into two pieces, and the waste materials (a) and (b) are discharged outward or upwardly, respectively, and the useful materials (a) and (a) are separated from the back splitting guide plate 5. ... guides the ground while restricting the path, which leads to intermediate rolls 8a and 8b.
Then, the left and right hand saws 9, 9 cut into the two pieces of active material a, a approximately evenly from both sides, and as shown in Fig. 3 (b). 11.11 Immediately after sawing and splitting the waste wood with skin and the product as shown in ), the back splitting disc 11.11
enters the sawing path and separates the product and waste material (or residual material), and the board material is sandwiched and sent out by upper and lower discharge rollers 14.14, and the starting end of the waste material faces immediately after the back splitting disk 11.11. It is separated and discharged using a sorting plate made of thin strip-shaped iron plates.

Next, another embodiment of the present invention will be described with reference to FIGS. 4 to 6. In this embodiment, the side pillow saw l, the supply roll 8a,
Bb, the upper and lower delivery rolls 7a, 7b, and the back splitting guide plate 5 are the same as those of the previous embodiment, but the hand saw 9
, 9 and the back splitting disk 11, 11 are installed on the upper side of the side pillow saw l, and one supply roll 13 and upper and lower supply rolls 13', 13'' are arranged further on the upper side lower part, Intermediate rolls 8a and 8b are pivotally supported between the back splitting disc 11 and the side saw saw 1, and when the back board A is fed from the supply roll 13 side, the back board A is first cut into the hand saw. 9.9, f56 figure (a
), the board material and the scrap wood with skin are sawn from the left and right, and then the back splitting disc 11.11 enters the sawing path formed by the hand saws 9, 9, and the delivered board material is passed through the side saw 1. Circular saws 2 and 3
．． 2, the product is split into two products and left and right waste materials as shown in FIG. 6(b), and the split products are carried out while being held by upper and lower delivery rolls 7a and 7b.

Further, the waste wood sawed and split by the hand saws 9, 9 is divided by tJl by a band-shaped sorting plate.

and in the second embodiment, the vertical axis 10.12 of the flat grinder jJ+i9,9 and the back splitting disc 11.11 and the motor 15
．． 15 on a gate-shaped frame that straddles the material transfer route.

The hand saws 9, 9 are of an overhang type, and the upper supply roll 13' is rotated at a fixed position as shown by the chain line in FIG.
” is pivotally supported on an arm that swings up and down, and this arm is supported so that it can be raised and lowered by an air cylinder, etc., and the supply roll 1 in the front is
3 is set low as shown by the stroke line, or it is moved up and down in conjunction with the supply roll 13", and the back plate A is placed on the supply roll 13 with its sawn surface facing "-". When fed, the back plate A is pressed against the feed roll 13' by the feed roll 13'' and then fed to the hand saws 9, 9 and sawed horizontally.The waste material generated from the back plate A during this flat sawing is It falls under its own weight and can be easily carried out by a belt conveyor installed at the bottom, and the ears are discharged to both sides as waste.

Next, 2 products and 2r waste materials are removed using the side pillow saw 1)
However, the lower intermediate roll 8b and delivery roll 7b are used as stationary rolls, and the upper intermediate roll 8a and delivery roll 7 are used as stationary rolls.
Move b up and down.

As described above, the present invention constitutes a side pillow saw by mounting a plurality of circular saws on a rotating shaft at intervals corresponding to the thickness of the product, and the plate surface is located in the material movement path of the side pillow saw. A flat saw is disposed orthogonal to the saw, and the flat saw is composed of a pair of circular saws whose sawing paths are on the same plane, and a part of the outer periphery is overlapped when viewed from the front and rear directions, and the side pillow saw is sent out. On the back side, we installed a delivery roll with multiple disks protruding from the outer circumferential surface to enter each sawing path. There is no need to carry out the second process of shaving one side, then splitting the saw, and then shaving the other side, making it possible to perform these multiple steps simultaneously in one process, significantly reducing manufacturing costs. can be reduced.

Moreover, if the backboard is sawed without selving it in advance, the position of the backboard cannot be controlled with a ruler, so sawing it in the width direction is extremely unstable even if it is clamped by moving rolls from above and below. However, the pair of flat saws cut into the back plate from both sides at the same time and cut with almost equal cutting resistance, so the material can be sawed in a white line shape without changing the direction of movement of the material. can do.
