Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a multi-barrel type peeling machine for peeling wood for chips or wood for construction.

(B) Prior art Conventionally, a wood container equipped with two peeling machines in which the upper part of a peeling rotary body was inserted into the lower opening of the wood container was published in Japanese Patent Application Laid-Open No. 61-284.
It is already known from Japanese Patent No. 403, and the upper part of the peeling rotary body is inserted into the lower opening of the wood container, and a number of slits are bored in the side wall of the wood container on the side where the wood descends as it circulates. , A peeling machine in which only the outer periphery of the peeling disk, which was pivoted on the outside of these slits, was exposed to the interior of the wood container was developed in the 6th century
2-5299, in which a number of slits are bored in the side wall of the wood container on the side from which the wood is pushed up, and a peeling disk is inserted into the wood container through these slits. The machine is already known from Japanese Patent Application Laid-Open No. 60-244501.

(C) Problems to be Solved by the Invention Among the known devices mentioned above, the first debarking machine has the advantage of being able to share the side walls of adjacent wood containers, but its debarking performance is only that of two machines. figure.

In addition, since the second peeler scrapes down the wood as it descends under its own weight during the circulation process, it hardly contributes to the circulation, and only the peeling blade of the peeling disk penetrates into the wood container in a point contact manner. Therefore, there is only a very slight peeling effect, and the third peeler has a large peeling disk that penetrates into the wood container, so it peels the wood while moving it from one side of the wood container to the other. When doing so, the end of the wood collided with the surface of the peeling disk, which hindered the movement. Furthermore, although a plurality of rotating bodies are employed, the width of each unit is narrow, making it impossible to increase the capacity.

Furthermore, all of the above-mentioned known methods circulate well when the wood is small in diameter, but the debarking efficiency is low.

(d) Means for solving the problem The present invention provides a plurality of openings in parallel along the longitudinal direction at the bottom of a wood container fixed to a machine frame, and has a large number of peeling blades on the outer periphery. The upper parts of the plurality of peeling rotary bodies rotating in the rotational direction are respectively fitted into the openings and are at approximately the same height, and the connecting bottom plate between the adjacent openings is at a midway point when viewed from the longitudinal direction. It is configured so that it forms a raised mountain shape.

The rear side of the connecting bottom plate in the direction of wood stripping movement is configured as a resistance guide section that slopes upward, and the front side is configured as a falling return section that allows the wood that has been pushed up once to be sufficiently lowered before being further stripped. Solved the above problems.

(E) Function When wood with bark is put into one end of the wood container, the barking blade of the barking rotor fitted into the lower opening will scrape up the wood towards the upper barking rotor and remove the bark. However, the wood that reaches the mountain-shaped raised bottom plate is caught by the resistance guide and braked, and in this state, the peeling blade forcibly peels the wood, so it can be efficiently peeled, and the peeling rotary body sequentially removes the skin. The wood that is being sent pushes up the wood that is in contact with the resistance guide part and moves to the falling return part. At this time, the wood descends significantly and is stripped by the next peeling rotor as it moves further to the side, and at this time,
When there are two peeling rotors, the side wall serves as the resistance guide part to provide sufficient braking action to the wood and improve the peeling performance,
After all, even small-diameter trees can be stripped with high efficiency without excessive circulation.

(f) Example An embodiment of the present invention will be described with reference to the drawings.

1 is composed of a side plate 2.3 having an open upper part and a sloped or curved lower part, an end plate 4 on the high side serving as an input section, and an ejection section 6 on the lower side having a shutter 5 that can be opened and closed. In this wooden container, the interval between both side plates 2.3 is wide, and a belt-shaped joint bottom plate 7 parallel to the length direction of the wood container l is provided between them, and the joint bottom @7 is provided in the middle thereof. 2 parallel to the length direction of the wood container l between both sides and the lower end of the side plate 2゜3.
A peeling blade 10 consisting of a large number of step-shaped plates is formed in one opening 8.9 and is projected on the outer peripheral surface of the cylindrical peeling rotor 11.12 at appropriate intervals in the circumferential direction and the length direction. The peeling rotary bodies 11 and 12 are fitted into the openings 8 and 9 so that their upper surfaces are approximately equal in height, and then the bearings are mounted on the machine frame 13! Rotatably supported by 5.

Further, comb-shaped slits 16 through which the skinning blades 10 pass are provided on the lower edge of the side plate 2.3 and on both side edges of the transfer bottom plate 7, respectively, and the skinning rotary body 11. 1
The rotation locus of the peeling blade 10 protruding from the peeling rotor 11.
When viewed from the length direction of 12, they are spaced apart in the horizontal direction.

The connecting bottom plate 7 has a chevron-shaped cross section, and the resistance guide portion 7 is curved upwardly on the opening 8 side.
a, and the opening 9 side is a falling return part 7 with a downward slope.
The wood pushed up as b slides down toward the side of the peeling rotary body 12, and the frame 17 that supports the connecting bottom plate 7 by welding has both ends attached to the front and rear end plates. Have you fixed it? It is constructed by welding one or more vertical plates 18 and a number of horizontal plates 20 at appropriate intervals, and the peeled bark is placed at the bottom of the peeling rotary body 11, 12. A gutter 21 is provided for collecting and dropping the skin to the center, and a carry-out conveyor (not shown) is provided at the bottom of the gutter 21. Rotate to move from left to right.

In the embodiment described above, the opening 8.9 and the skinning rotary bodies 11,1
Although one pair of 2 is shown, more than 2 may be combined, and in that case, a connecting bottom plate 7 is interposed between each peeling rotary body.

In the above-mentioned debarking machine, when a large number of pieces of wood with bark are fed from the input hopper at one end of the wood container l while rotating the debarking rotary bodies 11, 12, these pieces of wood are transferred to each debarking rotary body 11, 12. The skin is removed while being scraped from the left side to the right side in FIG. 1 by the skinning blade 10.

The wood scraped by the peeling blades 10 of the first peeling rotary body 11 is scooped up by the resistance guide portion 7a of the connecting bottom plate 7 and receives a resistance force, and in this state, the wood scraped by the peeling blades 10... As the wood is peeled, the lateral movement speed temporarily decreases at this part, but the peeling efficiency is significantly improved, and the wood that is pushed up to the falling back part 7b by the subsequent movement of the wood has an upper surface that is approximately the first peeling rotary body 11. The second skinning rotary body [2] which is at the same height is guided by the falling return part 7b and slides down, and from this lowered part the skinning blade 10 of the skinning rotary body 12 returns to the side plate 3 side. The skin is peeled off while being gently scraped up to approximately the same height as the scraping height by the first peeling rotary body 11.

At that time, the curved part at the lower part of the side plate 3 becomes a resistance guide part 7a and guides it upward while increasing the peeling efficiency, and the wood pushed up by the succeeding wood moves to one side plate 2 by its own weight.
The wood is circulated by falling to the side, and then undergoes the same peeling treatment as described above repeatedly. During this time, the wood container l and the peeling rotary body 1112 are tilted downward toward the discharge section, so the wood is It sequentially moves toward the discharge section and is discharged from the discharge section to the outside.

Therefore, in the above-mentioned peeling process, the wood is
Since it slides down after climbing over the 6th part, the circulation effect is suppressed and the peeling efficiency can be improved when a small diameter tree is peeled.

In addition, the fact that the upper surfaces of both the peeling rotors 11 and 12 are approximately horizontal and that the rotational loci of the peeling blades are spaced apart in the horizontal direction as described above together make it possible to increase the height of the wood container l. Capacity can be expanded while keeping storage capacity low.

Further, the diameters of the peeling rotors 11 and 12 may be the same or different diameters, and if the upper surface of the second peeling rotor 12 is somewhat lower than the upper surface of the first peeling rotor 11, the cross section By combining with the joint bottom plate 7 which forms a chevron, it is possible to further improve the peeling efficiency for small-diameter trees.

(G) Effects of the Invention Since the present invention is constructed as described above, the wood that is laterally fed by the peeling rotary body 12 at the rear in the peeling direction is received and guided by the resistance guide portion 7a of the transfer bottom plate 7. As a result, the wood that follows also receives resistance sequentially when the peeling blade 10
... allows for more efficient peeling.

Further, the wood that has exceeded the top of the conveying bottom plate 7 rapidly slides down and reaches the next peeling rotary body 12, and from this fallen state, it is lifted up by the peeling blades 10 of the peeling rotary body 12 while being peeled. As a result, even small-diameter trees that are susceptible to circulation can be accurately stripped while suppressing circulation.
