Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a wood peeling machine for treating wood for construction, pulp, etc. with 211 bark.

(B) Prior Art Conventionally, a wood container having upper and lower openings is mounted on a machine frame, and the upper part of a rotary body having a number of skinning blades on the outer periphery is inserted into the lower opening of the wood container. machine is already known.

(c) Problems to be solved by the invention: The above-mentioned known bark: The TQ machine sequentially transfers the wood input from the end of the wood container toward the end while peeling the wood using a peeling blade that rotates with a rotating body. Since the peeled wood was discharged from the end, it is suitable for peeling wood that is difficult to peel off, such as wood felled in winter + 1 JI, broadwood with hard bark, or frozen wood. If multiple rotating bodies are arranged in series or parallel to create a large-sized structure,
Wood felled in the spring, soft coniferous trees, etc., were excessively stripped and their woody parts were damaged.

Furthermore, if the wood debarking machine is configured to be small enough to be suitable for wood whose bark is easily peeled off or soft materials, the wood whose bark is easily peeled off will leave residual bark.

(d) Means to solve the problem In order to solve the above-mentioned problem, we have developed a large-sized wood peeling machine so that it can adequately debark wood that is difficult to debark. An attempt was made to reduce the amount of barking by supplying wood that is difficult to peel to the beginning of the wood container and feeding wood that is easy to peel to the middle of the container. Since the wood is only sloped downward by about 2 to 3 degrees towards the end of the wood, the wood that was put in will fall down and move from the place where it was thrown to the starting end of the wood container, and this wood will be moved by the wood that was put in after that. As a result, the woody part was severely damaged.

The present invention provides a peeling machine in which a wood container having upper and lower openings is mounted on a machine frame, and a part of a rotating body having a peeling blade on the outer periphery is inserted into the lower opening of the wood container. When processing wood that is difficult to debark by installing a partition in the middle of a wood container so that it can be in a working position and a non-working position, the partition plate is set in a non-working position and the wood is placed on the starting end side of the wood container. When processing wood or soft materials that are easy to peel, the problems mentioned above can be avoided by dividing the wood container in the middle with a partition plate to create a working position and reducing the peeling process. solved.

(e) Function When debarking wood that is difficult to debark, such as wood felled in winter, hardwood, or frozen wood, put the partition plate in the non-working position and insert the wood from the beginning of the wood container.The wood will rotate. 21 + complete skin treated with a skinning blade for the entire body 11
1 can be done.

Also, when treating sword-leafed trees or wood felled in the spring with 111 bark, if you put the partition plate in the working position and throw the wood into the lower side of the partition plate, the wood will tend to collapse toward the starting end. Since the wood is caught by the partition plate, the wood that is put in later will only be placed on top of the wood that was put in earlier and will not move to the starting end, and the wood at the bottom will be sent to the discharge section at the end one by one due to the rotation of the rotating body. transfer and will not be excessively exfoliated.

(f) Examples, 4. : To explain one embodiment of the invention with reference to the drawings, the wooden container l is open at the top and bottom, and is gently sloped so that the discharge port is 1 cm lower, and below that, there are many peeling teeth on the outer peripheral surface. Two cylindrical rotating bodies 3,3 with 2ψ fixed to a spiral run are arranged in series and supported, and the upper part of these rotating bodies 3.3 is inserted into the lower opening 4 of the wood container 1. The lower part of the side plate 1a on the side where the peeling teeth 2 of the rotary body 3 of the wood container 1 scrape up the wood is curved toward the upper part of the rotary body 3, and the side plate tb on the other side is partially fitted.
The lower part of is inclined downward and approaches the circumferential surface of the rotating body 3,
The lower edges of those side plates 1a and lb have the skinning teeth 2...
A comb-shaped notch 5 is provided through which the material passes. Also,
Double 8! A notch similar to the notch 5 or a shallow notch 5dψ as shown in FIG. A band 6 or a plurality of protrusions of appropriate length are carefully attached to prevent a piece of wood from being caught between the lower edge of the side plate between the notches 5, 5 and the rotating body 3, and the band 6 Alternatively, the row of protrusions may be provided on the same circumference as the skinning teeth 2, and in this case, the partition plate 12, which will be described later, is lowered to the lower side of the skinning teeth 2.

Furthermore, the upper part of the bearing at the connection between the front and rear rotating bodies 3 is provided with an arc-shaped guide plate 7 that coincides with the outer circumference of the rotary body 3, and the outer circumference of this guide plate 7 has a larger diameter on the discharge port lc side. Tipper”
The second receiver fixes the ring 7a or the protrusion.

The upper portions of the side plates 1a and 1b of the wood storage body 1 are curved inward, and the receiver of the 1st curve r;
The corresponding parts are cut out and formed into guide grooves 8, 8.
A gate-shaped support frame 9 is erected at a portion corresponding to the guides l+X78, 8, and a guide groove 10 provided inside the column of the support frame 9, the guide groove 8.8 and the side plate 1a,
The partition plate 12 fitted into the guide bodies II and +1 provided on the inner surface of the lb is suspended by the wire 15 of the hoist 13 on the support frame 9, so that the hoist 13 cannot be rotated in the forward or reverse direction. When the partition plate 12 is driven, the partition plate 12 moves up and down, and when it is lowered, the lower end of the guide plate 7 is stopped by the ring 7a or the edge of the band 6 near the U protrusion lc. 3
Slides on the circumferential surface of the

The lower end of the partition plate 12 may be configured in a shape that matches the curved portion of the side plate 1a or the inclined portion of the side plate 1b and the circumferential surface of the rotating body 3, or the side on which the wood circulating due to the peeling process moves downward is a second side. This is to prevent the wood thrown into the discharge port 1c side of the partition plate 12 from collapsing to the upper side of the partition plate 12 in the lowered state as shown by the dotted line in the figure.

In addition, a guide body 11 sunk into the inner surface of the side plates 1a and lb
゜11 is a pair of guide protrusions 18. +6 or by fixing the guide protrusion 16 only on the feeding side, and the guide protrusion 16 on the side of the lumber moving force has a cross section in the direction of the water flow so that it does not become an obstacle to the movement of the lumber. It is formed into a right triangular shape with the lower side gradually becoming higher so that both sides of the partition plate 12 are received by the vertical plane.

Furthermore, the position where the partition plate 12 is provided is not limited to the portion where the receiver corresponds to the ring 7a or the band 6;
If the guide body 11 is installed at a location other than that, a pair of guide protrusions 1B and 16 are provided to guide and receive the partition plate 12, and in this case, the guide body 11 is provided with a pair of guide protrusions 1B and 16 to guide and receive the partition plate 12. Of course, a groove 8.8 is provided.

Note that if the upper portions of the side plates 1a, lb are formed straight, the guide groove 8 can be omitted.

In addition, a vertical groove (vertical length A) is bored in one side plate 1a or 1b, and a guide rail 18.18 is connected to the upper part of this groove A on the outside of the lower part to horizontally extend the partition plate 12. The lower end of the partition plate 12 inserted into the wood container 1 is received by the band 6 or the ring 7a as in the previous embodiment, and the front end is held by the side plate 1b or the other side plate 1b. 1
It may be received by a guide body 11 provided on the inner surface of a.

Reference numeral 19 is a cam plate whose bottom part is approximately equal to the outer peripheral surface of the rotating body 3 and whose high part is raised in an arc shape at one or more places up to approximately the same height as the skinning teeth 2, and is fixed to the end of the rotating body 3. A rotary cam plate 19a, which intermittently pushes up the moving wood to promote its movement, is also attached to the shaft 20, and has a raised portion on its outer periphery. 21 is an input section, 22 is an input conveyor, 23 is a waste conveyor, 24 is a material conveyor, and 25 is a shooter.

In the above-mentioned wood peeling machine, when peeling wood that is difficult to peel, the partition plate 12 is raised by the winding machine 13, and the rotating body 3 is driven to peel a large number of pieces of wood to the starting end side of the wood container l. When the wood is put into the wood, the peeling teeth 2 roll the wood from right to left as shown in Figure 1, peeling it and scraping it up. The recycled wood passes over the lowered shutter 17 and is carried out from the discharge port IC.

Also, when peeling wood that is easy to peel, use rc+ to that extent.
