Description

[Detailed Description of the Invention] Conventionally, when wood is put into a cylindrical body and stripped of its bark, the transfer of the wood is poor, so while an unpeeled portion remains on one side, the bark progresses excessively on the other side, causing the wood to deteriorate. This has the disadvantage that the wood is scraped off, resulting in wood loss and producing defective chips.

The purpose of the present invention is to improve the above-mentioned drawbacks and to further improve the peeling efficiency.The present invention aims to improve the peeling efficiency while also improving the peeling efficiency. A rotating shaft is provided on the outer side of the lower part of the cylindrical body, and a rotating body fixed to the rotating shaft and having unevenness on the outer circumferential surface is inserted into the cylindrical body through a cutout window bored in the lower part of the cylindrical body. The present invention is characterized in that the rotating body is configured to be rotationally driven in the wood scraping direction.

To explain the embodiment shown in the drawings below, l is the machine frame 2.
It is a cylindrical body that is supported above and consists of a cylindrical part and a gutter-like part that is open at the top as shown in FIG. A large number of notched windows 3, 4, etc. along the direction are bored in parallel and close to each other, and the opening on the starting end side of the cylindrical body is configured as an input port 5.

Reference numeral 6 denotes a main shaft provided below the cylindrical body l, on which a number of discs 7 are mounted at predetermined intervals, and these discs 7 are combined in an appropriate number.

A large number of striking plates 9, which are rotatably supported on the outer periphery of the discs 7, by means of spindles 8, are formed by notches formed in the lower part of the cylindrical body as the main shaft 6 rotates. Pass through window 3...

Reference numeral 10 denotes a subshaft that is forcibly driven by a suitable transmission device and supported on the outer side of the lower part of the cylindrical body 1, and a part of the outer circumferential portion of the auxiliary shaft 10 extends from the cutout window 4 in the lower part of the outer side of the cylindrical body 1. A large number of discs 11 are fixed and constitute a rotating body by rotating in the direction of raking up logs while facing inward, and the discs 1
The circumferential surface of 1 is engraved with many unevenness.

A pulley 12 is attached to the end of the main shaft 6 and is driven by a motor 17 via intermediate pulleys 13 and 14 and belts 15 and 18.

18 is a shutter provided on the discharge side of the cylindrical body 1,
It has a pair of racks 20.20 fitted between groove frames 19.19 provided on both sides, and a pinion 21.21 attached to a horizontal shaft 21a driven by a motor meshes with the racks 20.20. Therefore, when you operate the switch on the control panel, the motor rotates in the forward and reverse directions, and shutter 1
8 goes up and down.

If the bark is likely to peel off due to the time of felling the logs or differences in tree species, or if the wood is young and soft, the shutter 18 is lowered to speed up the removal of the wood, thereby preventing damage to the wood and bark. If it is difficult to peel off, use shutter 18.
By increasing the temperature and lengthening the residence time of the log, more complete debarking is achieved.

In this example, the shutter 18 is vertical, but if the shutter 18 is installed obliquely as shown in FIG. 5(b), the wood can be sequentially and smoothly discharged.

At this time, since the racks 20' and 20 degrees provided on the upper surface are engaged with the pinions 21 and 21, the shutter 18 can be moved up and down.

Further, a roller 18a may be provided at the upper edge of the shutter 18, which is installed upright or obliquely, and the roller 18a may be forcibly driven by a motor 18b in the direction of free rotation or discharge of logs.

Reference numeral 22 denotes a rocking body having a large number of irregularities on its inner circumferential edge and whose upper part is rotatably pivoted to the cylindrical body l, which is rocked by a crank arm or other reciprocating mechanism, and is struck up by the striking plate 9. This promotes the circulation of the logs and causes the bark to peel off when the logs collide.

Further, as shown in FIG. 6, the striking plate 9 has a substantially oval shape, and has many irregularities on the negative side and a smooth curved surface on the other side. As shown in Fig. 1, rotating the main shaft 6 clockwise will cause the uneven side to strike the bark, making it possible to easily strip the bark of logs that are difficult to peel off depending on the time of felling or tree species. 9 hits the bark with its smooth curved surface, so it can prevent damage to the wood when peeling the bark of easily peeled logs or soft logs.

Further, when the main shaft 6 is to be rotated in the forward or reverse direction, it can be easily done by operating a changeover switch on the operation panel, and there is no need to replace the striking plate 9, which is extremely convenient.

In this case, it is better to install a sub-shaft 10 having a large number of disks 11Φ symmetrically on both sides of the lower part of the cylindrical body l, and to switch the direction of rotation to a direction that circulates the raw wood at the same time as the main shaft 6 is switched between forward and reverse directions. The sub-shaft 10 on the side into which the logs 9 and - enter either rotates in the direction of feeding the log or stops it.

Next, to explain the effect, the log is not cut (approximately 2
．． When a suitable number of logs are inputted through the input port 5 of the 1 m) mill, as the main shaft 6 rotates clockwise, the striking plate 9 rotates clockwise in FIG. 1 and strikes the surface of the logs.

Then, the beaten log is thrown upward to the right and collides with the disk 11..., and the few yen 1i11-. are rotating in the direction of scraping up the log, that is, in the clockwise direction in Fig. 1, Since the log is picked up and raked up while engaging the protrusions, the log is promoted to transfer, circulate, and spring up, and the bark is scratched by the protrusions to promote debarking.

In addition, the log rarely moves in a posture parallel to the length direction of the cylindrical body l, and takes various tilted postures, and one end of the log collides with the rocking plate 22 and the other end collides with the disk 11. When logs in the same opposite orientation collide, the rocking plate 22 pushes the logs to the side of the row, and the lower end of the disk 11 is pushed up or thrown up, causing the logs to become entangled with each other. It circulates smoothly and the logs are evenly debarked all over their circumference.

At this time, the swing plate 22 may be omitted.

As described above, the present invention has a cylindrical body for storing and peeling wood, which is horizontally suspended so as not to rotate, and a rotating shaft is attached to the outside of the lower part of the cylindrical body, and the outer circumferential surface of the cylindrical body is fixed to the rotating shaft. A rotating body having an uneven surface is inserted into the cylindrical body through a cutout window bored in the lower part of the cylindrical body.

Since the rotating body is configured to be rotationally driven in the direction of scraping up wood, the rotating body that rotates while facing the lower side of the cylindrical body scrapes up the wood rolling inside the cylindrical body. This can prevent one side of the wood from being excessively debarked, causing significant damage to the woody part, and preventing the bark from remaining on the other side. .

In addition, the rotary body can bounce up wood in various postures within the cylindrical body to prevent it from getting tangled, and it can scrape off the bark by coming into contact with the circumferential surface of the wood, thereby improving the peeling performance.
