Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a wood stripping machine for stripping the bark of wood.

(b) Prior Art Conventionally, a wood container has an opening at the bottom, which has an input port on one side and a discharge port on the other side, and the upper part of a drum having a large number of skinning teeth on the outer peripheral surface is connected to the opening. A wood peeling machine is already known in which wood is loaded into a wood container from an input port facing the wood, and is peeled while being moved toward a discharge port by rotation of the drum.

(c) Problems to be solved by the invention In the known wood peeling machine, even though the discharge side of the wood container is lowered, the front part (direction of wood movement) shown in FIG. 6(a) has a small diameter. In this state, it moves easily as the drum rotates, but if the front part has a large diameter as shown in (b) or there is a large bump on the front part as shown in (C), it is difficult to move.
There is a drawback that the wood becomes clogged, reducing the peeling performance and damaging some of the wood.If the inclination of the wood container is increased to improve this drawback, the peeling process will be insufficient and residual bark will be produced.

In particular, when dropping wood into a loading slot, the wood is fed horizontally using a conveyor or forklift, but some wood may be placed diagonally or in an upright position, and when doing so, parts that are difficult to move, such as large diameter parts, may be thrown in. When the wood was placed in front, it was placed diagonally toward the inlet and the wood was not moved, and the wood that followed was placed on top of it, making it impossible to layer the wood.

(D) Means for Solving the Problems The present invention provides a wood container with an opening at the bottom, which has an input port on one side and a discharge port on the other side, and has a large number of peeling teeth on the outer peripheral surface. In a wood peeling machine that peels wood input into a wood container from an input port with the top of the drum facing the opening while moving it toward a discharge port by rotation of the drum, a peeling tooth on the starting end side of the rotor. If the thicker side of the wood comes first when the wood is fed in, the diameter of the rotor can be gradually increased so that the working surface of the peeling teeth is tilted toward the discharge port. Even if the wood has a large diameter and a large weight, the successively raised peeling teeth form a tapered or trumpet-shaped trajectory surface and push the wood toward the discharge port. The above-mentioned problem was solved by forcibly moving the end of the rotor and laying it down on the rotor.

(e) When bark-based wood is fed into the wood container in a sideways position from the input port using a conveyor or the like while rotating the action rotor, the barking teeth transfer and circulate the wood while peeling the wood, and the wood is sequentially moved during this time. The debarked wood is then discharged from the outlet.

If the large-diameter side or the part with a large bump falls off first when charging, the working surface of the peeling teeth, whose upper side is successively higher, repeatedly pushes up toward the discharge port side,
As a result, the leading end moves sequentially, so that the wood falls sideways, and thereafter moves toward the discharge side due to the inclination of the rotor and the pushing action of the following small-diameter wood.

(F) Example An example of the present invention will be described with reference to the drawings. L is a wooden container fixed to the machine frame 2 in an inclined manner so that the input port 3 side consisting of a hopper is high and the discharge port 4 side is low, The upper part is open, and the lower part is formed into an opening 5 over almost the entire length.

Reference numeral 6 denotes a rotor whose both ends are rotatably supported on the machine frame 2 by shafts 7, 7, and the outer circumferential surface has a large number of spiral teeth 8 which are gradually higher on the rear side in the direction of rotation and have a plurality of irregularities. The rear side in the direction of movement of the wood (
The peeling teeth 8a... on the upper side) are sequentially higher on the rear side, so their working surface forms a tapered trajectory surface, and the range in which the peeling teeth 8a... are provided is the length of the wood. About 1.5 times to 1/3 of the length, preferably the same length to 1/3
Make it 2.

Next, to explain another embodiment in which the tapered action locus surface is obtained, the rotor 6 itself is formed into a tapered shape, and the peeling teeth 8φ are provided on the circumferential surface of the rotor 6 so that the surface thereof is perpendicular to the axial direction or Weld perpendicular to the surrounding surface.

Then, on the side edge of the opening 5 of the wood container 1, there are notches 10, which have the same depth through which the peeling teeth 8 pass, and which become progressively deeper so that the peeling teeth 8a... pass through. Many notches! ! ...and are drilled there.

Further, some of the skinning teeth 8, 8a are provided near (front, rear or side) the skinning teeth 8, 8a, preferably on the sides as shown in FIG.
Both lower receiving plates 13 are welded together, and a guide plate 15 with an arcuate outer circumferential surface and serving as peeling prevention teeth is attached to the upper surface of the lower receiving plate 13 by a port. The guide plate 15 is removably screwed, and the height of the guide plate 15 in the installed state is higher than the peeling teeth 8, 8a, and is made of soft materials such as wet wood or soft wood, or materials that are easy to peel. When peeling, the guide plates 15... are attached to both receiving plates 13.
When attached to ..., some skinned teeth adjacent to it 8゜8
a does not come into contact with the surrounding surface of the wood, thereby preventing damage to the wood while performing appropriate peeling. When the guide plate 15... is removed, all of the peeling teeth 8, 8a... come into contact with the wood and peel the wood, and if the guide plate 15 is increased or decreased depending on the difficulty of peeling or the hardness or softness of the material, the peeling is done. The arcuate surface of the guide plate 15 has a large radius at the middle and a small radius at both ends. Peeling teeth instead of 8
A peeling prevention plate having grooves covering the top and side surfaces may be fitted onto the peeling teeth 8 and screwed in with horizontal screws.

Fig. 4(a) The outer peripheral surface of the guide plate 15 is corrugated, and although it has a feeding function, it does not damage the wooden part.The attachment and detachment structure is the same as the above example, and the tooth The overlapping portion of the receiving plate 13 and the guide plate 15 has a ridge and a groove as shown in FIG. 5(a).

The lower part of the wall plate 1a on the input port 3 side of the wood container 1 is inclined downward toward the feeding direction, and is located on the discharge port 4 side from the input port 3 and on the side where the skinning teeth 8 scrape up the wood. As shown in FIG. 3, the lower part of the side wall 1b of the rotor 6 is curved toward the upper surface of the rotor 6, and the upper part thereof is inclined inward.

The wood scraped up along the lower arcuate surface by the peeling tooth 8 rapidly falls toward the other side due to the inward slope that follows, allowing the wood to circulate smoothly. The upper part is inclined inward to further promote the circulation.

In the above-mentioned wood peeling machine, when the rotor 6 is rotated and the wood is fed into the inlet 3 using the belt conveyor 16, forklift, horizontal chain conveyor (feeding from above the guide plate 17), or other conveying means, each The wood is guided around the circumference by both side walls of the input port 3, and the uneven rear end is pushed out and placed on the rotor 6 while sliding down the slope at the bottom of the wall plate 1a, and the peeling tooth 8.8a is In Figure 3, the wood is pushed up from the side wall 1c side to the other side, peeled while being rolled, and then pushed up along the side wall 1b in the first stage and guided inward by the inwardly inclined part at the upper part.
It rapidly circulates to the lower part of 1c and is further stripped.

The wood thus peeled is discharged to the outside from the discharge port 4 and conveyed by a discharge conveyor.

When the wood is loaded, the wood with a large diameter is 1. If a person falls into the wood container 1 from the % side or the side with a large bump, the wall plate 1a side will become higher one by one and the peeling tooth 8a.
・It is pushed up by the action trajectory surface which is tapered or straight, and is sequentially moved toward the discharge port 4, so it falls sideways and is forcibly pushed out. Since it is pushed by the wood, it smoothly moves to the discharge port 4 side.

(G) Effects of the Invention Since the present invention is configured as described above, when a large number of pieces of wood with different diameters are put into the wood container 1 from the input port 3, the diameters at both ends are significantly different, and the large diameter part If a person falls first, or if a person falls first on the side with a large bump, etc., the peeling teeth 8a on the upper side of the rotor 6 form a Ku-shaped to N-shaped action locus surface. However, this causes the wood to move toward the discharge port 4, and the wood hangs from one side to the other in a cross-like manner, preventing subsequent wood from clogging, and after being forced down. It is possible to reliably peel off the skin while transferring it smoothly.
