Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bark discharge device in a bark peeling machine that peels the bark of wood and discharges it outside the machine.

(B) Prior Art Conventionally, a rotor is provided at the lower opening of a wood container as shown in FIG. 11(a), and a peeling machine with a number of peeling blades protruding from the outer circumferential surface of the rotor and a drum barker are used for peeling. In order to inherit the park and wood that has been discharged, and to peel the remaining bark and remove the bark, two parallel rotors are installed in the two openings at the bottom of the wood container, as shown in Figure (b). The installed park separator is already known.

(c) Problems to be Solved by the Invention The known peeling machine shown in FIG. 11(a) removes the peeled bark from the notches (
In particular, the debarking teeth were discharged from the notch (where the debarking teeth exit), but the debarking teeth are arranged in a spiral shape with a large lead angle to increase the pressing force against the wood and encourage the movement of the wood. Because the spacing was wide, there was little chance of ejection, and the depth of the notch was slightly larger than the height of the peeling teeth to prevent the wood from digging into the notch, so it was peeled off. The bark is poorly discharged, and the pushing side A (
Bark was deposited on the pipe No. 12, which deteriorated the circulation and debarking performance of the wood, and also caused the bark to be discharged from the discharge port following the wood, making it difficult to remove it.

In addition, in the method where rotors are installed side by side, bark accumulates between the two rotors B, which becomes an obstacle and obstructs the circulation of wood. No evacuation effect was obtained.

(d) Means for solving the problem The present invention provides a method in which a rotor is disposed opposite to the lower opening of a wood container having at least an open lower part, and a large number of peeling teeth are protruded from the outer periphery of the rotor at intervals, A shoulder tooth is fixed between the skinning teeth and closer to the rear of the skinning tooth, and the shoulder tooth is slightly lower than the skinning tooth, so that the shoulder teeth reduce the peeling action of the skinning tooth pushing up the wood. The above-mentioned problems are solved by ensuring that the peeling teeth catch the peeled bark in this state and discharge it from a wide gap at the exit side notch without damaging the wood.

(E) Function When the rotor in the peeler rotates, a large number of peeling teeth protruding from the outer peripheral surface of the rotor enter the opening of the wood container through the notch on one side and peel the wood.

At this time, the shoulder protruding teeth are located at the rear in the direction of rotation between the stripping teeth, and are slightly lower than the stripping teeth, so they do not become an obstacle when the wood comes into pressure contact with the stripping teeth, and good stripping can be performed. The peeled bark moves towards the notch on the other side while being caught in the shoulder tooth, and when the shoulder tooth escapes from the notch,
The notch is at a height that allows the skinned teeth to escape, and the shoulder teeth are lower than the skinned teeth, so the gap between the shoulder teeth and the notch is large, ensuring that even large parks can be ejected reliably. can do.

In addition, when installed as a park separator in conjunction with the discharge part of a drum bar, the wood that is discharged from the drum barker together with the park and transferred to the park separator will be removed by the peeling teeth as the rotor rotates, and the shoulder teeth will peel off the remaining bark. The bark removed and the bark transferred from the drum barker are caught and reliably discharged without impairing the peeling action, similar to the peeling machine.

(F) Embodiment An embodiment of the present invention and its related structure will be explained with reference to the drawings. The wood container 1 has a wide opening at the top and a narrow opening at the bottom, and the lower end is formed into the opening 2, or the upper part of the starting end is opened. The rotor 3 is partially inserted into the lower opening 2, supported by a shaft 3a, and rotated by a motor via a speed reducer. .

Further, on the outer peripheral surface of the rotor 3, a large number of peeling teeth 5 and e whose rear part in the rotational direction is raised in a stepped manner are spirally connected, and on both sides of the lower opening 2 of the wood container 1, the A large number of notches 6 into which the skinning teeth 5 go in and out are bored in a comb-like shape.

During the peeling tki5.5, as shown in FIG. A partially recessed shoulder tooth 7 is fixed at the rear, and this shoulder tooth 7O has one or more protrusions on the front surface in the direction of rotation, and the fixed position is at the same position as the other tooth 5. Since it is on the rotation trajectory, it enters into the wood container 1 through the notch 6 and exits through the notch 6 on the other side.

Further, the shoulder protruding teeth 7 are lower in height than the peeling teeth 5.

The thickness is thin, and the upper surface of the protrusion on the front surface is approximately parallel to the outer peripheral surface of the rotor 3, and the tip thereof is smaller than a right angle.

In the above-mentioned device, the wood container l and the rotor 3 are inclined so that the discharge side at the other end is lower than the input section at one end, as in the conventional one, and while the rotor 3 is rotated, the wood is removed from the input section. When you put in the wood, it peels fI!
15.- and shoulder protrusion m7 enter into the wood container 1 through the notch 611 on one side, and the peeling teeth 5... rotate while pushing up the wood to peel off the bark and move from one side to the other. The wood on the other side is circulated to one side by pushing up the wood on the front side.

When the peeling teeth 5... debark the wood while pushing it, the shoulder protruding teeth 7 are lower and rearward than the paring fA5, so the paring teeth m5 and the skewer are attached to the shoulder protruding teeth 7... The bark is peeled while pushing up the wood reliably without being disturbed, so there is no deterioration in the barking performance, and the protrusion of the shoulder tooth 7II protrudes from the front in the direction of rotation, so the bark can be removed securely. At that time, if the protrusion protrudes in the direction of rotation, it will easily bite into the wood and cause damage, but the peeling teeth 5 catch the peeled bark immediately after pushing up, so it will not stick to the wood. Without biting in, when moving to the notch 6 on the other side in this state and exiting from the notch 6, the gap between the top of the shoulder protruding tooth 7 and the upper end of the notch 6 is in the case of the peeling tooth 5. Since it is larger, the hooked bark can easily escape, and even if the bark is folded in two, it can be discharged easily and efficiently by making the shoulder teeth 7 thin.

Therefore, the bark does not accumulate on the upper side of the notch 6, and the peeled bark does not circulate together with the wood and deteriorate the peeling performance.

When the above-mentioned debarking machine is connected to the outlet of the drum barker 8 to form a park separator 9 as shown in FIG. The remaining bark that has not been discharged flows into the inlet of the eight-fold separator 9.

Then, the inflowing peeled bark is rapidly discharged by the shoulder teeth 7, the remaining bark is efficiently peeled with little bark, and the peeled wood is discharged from the discharge port onto the carry-out conveyor 10. and then transported out.

At this time, the wood contains some bark, but it is extremely small, so it can be fed to the chipper after a slight sorting process.

Reference numeral 11 indicates a parker's opening, and reference numeral 13 indicates a receiving tooth obliquely welded to the lower inner surface of the wood container 1 on the side where the peeling tooth 5φ etc. enters.

Next, the side shell type peeling machine will be explained with reference to Figures 6 and 7.
Reference numeral 3 denotes a rotor in which skinning teeth 5 and shoulder protruding teeth 7 similar to those described above are arranged in combination, and a sub-rotor 12 is pivotally supported in parallel on the upper part of the exit side.
2 may be arranged and welded with the skinning teeth 5 and lower shoulder teeth 7 in the same manner as the rotor 3, but as shown in FIG. 8, only the shoulder teeth 7 may be welded. After the rotor 3 performs the peeling process and the shoulder protrusion process, the sub-rotor 12 takes over, and the peeling teeth 5... and the shoulder protrusion teeth 7... can perform the peeling process and the shoulder protrusion process. The bark is caught on the front protrusions of the shoulder teeth and is efficiently discharged, and the wood is not damaged by these shoulder teeth 7.

Moreover, by implanting only the protruding shoulder teeth 7-. on the sub-rotor 12 and reducing the diameter of the sub-rotor 12, the protruding protrusion can be performed without damaging the wood.

Furthermore, between the rotor 3 and the sub-rotor 12, bark is efficiently discharged by the shoulder teeth 7 of the rotor 3, so there is very little bark deposited, and this small amount of bark follows the movement of the wood. It moves to the sub rotor 12 and is discharged.

Of course, this side shell type peeling machine can also be used as the park separator 9 of the drum barker 8.

In the single-barrel type peeling machine described above, if the peeled bark is very hard, the amount of wood is small, or there is no wood and only the bark remains in the wood container 1, the peeling tooth 5 Also, the protruding shoulder teeth 7 may float up on the exit side from the wood container 1 and may not be ejected.

In such a case, as shown in Figures 8 to 10, the wooden container 1
An upwardly curved partition plate 15 is placed parallel to the rotational direction of the rotor 3 on the protrusion 6a forming the lower notch 6 on the side where the skinned teeth 5 and shoulder teeth 7 exit. A vertical support par 16 is fixed along the top of the notch 6 from the side surface of the partition plate 15. These partition plates 15
A large number of support bars 16 are arranged at appropriate intervals in the portion of the rotor 3 other than the discharge port side, and the partition plate 15a at the end of the rotor 3 is connected to the partition plate 1 as shown in FIG.
5 and approximately above the center of the rotor 3.
It has been a long time since.

If it is difficult to discharge the bark as described above, the wood to be debarked moves in the direction of arrow A in FIG. Since it is guided to the partition plates 15 and further received by the support bar 16, it is not pushed up along the side plates and can be reliably discharged.

Moreover, since the wood and bark are guided to the long and tall partition plate 15a on the discharge port side of the wood container 1, the bark can be discharged while the wood is being discharged well.

Experiments have shown that if the partition plates 15, 15a and support bars 16 are provided, bark can be discharged very efficiently, so there is no need to use a double-barrel type, but depending on the type of tree, the time of felling, moisture content, etc. A double drive system is used when it is difficult to discharge waste, but in such cases rotor 3 and sub rotor 1
The partition plate 15.15a is provided between the two, and if the wood container 1 has a significantly large capacity, it is also provided above the sub-rotor 12.

Further, the partition plate 15.15a and the support bar 16 are applied to the above-mentioned single-barrel type or double-barrel type peeling machine and park separator.

(G) Effects of the Invention As described above, the present invention includes a rotor 3 that is disposed opposite to the lower opening 2 of the wood container 1 which is open at least at the lower part, and a number of debarking techniques 5 are arranged at intervals around the outer periphery of the rotor 3. Protruding apart,
The shoulder teeth 7 are fixed between the skin teeth 5Φ and near the rear of the skin teeth 5, and the shoulder teeth 7 are lower than the skin teeth 5. The protruding tooth 7 is the denuded tooth 5...
The wood does not become an obstacle to the barking process, and the wood can be sufficiently pressed against the barking teeth 5 by its own weight to perform good barking, and the shoulder teeth 7 can move the stripped bark to the adjacent barking teeth. The wood can be hooked near the rear between 5 and 5 without damaging it, and be ejected easily and reliably from the notch 6 on the other side, and the peeled bark can be quickly ejected from the inside of the wood container 1. It is possible to improve the peeling performance and reduce the amount of bark discharged from the discharge port following the wood, thereby significantly reducing the sorting work.
