DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below in more detail.

In FIG. 1, the main body 1a, 1b of this cedar tree peeling device has two lower surfaces made of square steel, stainless steel, etc., in order to prevent accumulation of debris from the bark. The bridge is supported by two or three bridges.
The support bases 5a and 5b on which the rubber sheet 9 is stuck on the upper surface are introduced.

On the upper portions of the timbers 2 and 3, rotating shafts 6 and 7 which respectively rotate in the same direction for installing the cedar pillars 4 are bridged. A rotary roller 8a having a large diameter and a rotary roller 8b having a small diameter at the right root portion 4b having a large column diameter are adjusted with the split type inclined coupling 10 or the like to adjust the position according to the length of the cedar pillar 4, and the rotating shaft is rotated. 6 and 7 are fixed. Of course, when the installation direction of the cedar pillar 4 is reversed, the fixing of the rotating rollers 8a, 8b to the rotating shafts 6, 7 is also reversed accordingly.

A nozzle carry box 11 having reciprocally movable water injection nozzle ports A, B, etc., installed below is installed so as to be movable along the square bar 3 and comes off the tip 4a and the root 4b of the cedar pillar 4. And it is installed in a reciprocable state.

In the nozzle carry box 11, an H-shaped steel material 12 is stretched between the main bodies 1a and 1b so as to be in contact with the box 11, and a cable bear 28 is mounted on the H-shaped steel material 12, and a water hose 19 is contained therein. It is attached. The H-shaped steel material 12 may use another shape material.

Similarly, the cable carrier 28 of the H-shaped steel material 12
The signal for moving the box 11 left and right, that is, the operation of directly receiving the water pressure directly injected from the water injection nozzles A-1, B-1 and the like from below into the receiving plate 17 and the like,
A cable for transmitting signals from the sensors A-3, B-3 and the like to the main control device is also provided.

FIG. 2 shows the details of the nozzle carry box 11. In FIG. 2, the nozzle carry box 11 is provided with a roller box 16 equipped with slidable rollers 15 and the like, a switching box 13 having a built-in jetting water switching valve, etc. The rotary nozzle A-1 in which the injection port A automatically rotates by the water pressure for injecting the nozzle and the fixed nozzle B-1 in which the injection port B does not rotate are integrally provided via a slide plate 14 which can be adjusted up and down. I have. In addition, the rotating nozzle A-1
Is suitable for the first rough stripping operation, so that it is operated earlier than the fixed nozzle B-1 even when the nozzle carry box 11 is restored, so that A-1, B-1,.
You may install in three injection ports in order of A-1.

FIG. 3 shows a rotary nozzle A-1 and a fixed nozzle B-
1 shows a detailed explanatory view of the arrangement relationship of FIG. The rotating nozzle A-1 is also called a turbo nozzle, and the overlapping of the peeling can be prevented by rotating and changing the position of the injection port A. Generally, the water is strongly spread upward and roughly cut. Accordingly, as the rotary nozzle A-1 rotates, for example, when the surface of the cedar pillar 4 has irregularities, the water pressure effectively operates from different directions, and the finished surface is completely peeled off, which has not been obtained conventionally. Refined smoothness could be obtained. In addition, the fixed nozzle B-1 was effective in peeling the thin film, and by incorporating the advantages of both, skillfully adjusting and operating each individual water pressure, it was possible to obtain an unprecedented highest effect.

The greatest effect of the present invention is the conventional method. As shown in FIG. 5, conventionally, water is sprayed from above to peel off the skin of the cedar pillar 4, or the cedar pillar is placed on the ground and In the present invention, water is sprayed on the lower surface of the cedar pillar 4, that is, the so-called bottom surface, and the skin is peeled off, while using a hydraulic barker carefully and peeling off the skin to clean it. Is the way. Therefore, as shown in FIG. 2, for example, when the former is adopted, since water is sprayed from the upper surface portion, the variation difference β between the tip portion 4 a and the root portion 4 b of the cedar pillar is large,
On the other hand, when the apparatus of the present invention is used, since the variation difference α is very small because it is from the lower surface portion, the variation of the water jet is small and the effect of peeling is remarkable. for that reason,
Although the conventional method had a problem of peeling spots, a beautiful and elegant floor column could be obtained in the present invention. In the present invention, in order to further maximize this effect, the tip 4
Further, the difference α between the “a” and the root portion 4b is raised and lowered by using an electronic control method (not shown). By fine adjustment, the peeling efficiency of the cedar was improved, and the skin was evenly peeled off.

Further, switches A-2 and B- which directly receive and sense the water pressure jetted from the rotary nozzle A-1 and the fixed nozzle B-1 from above on the nozzle carry box 11 are provided.
There is a function for sensing the pressure by raising and lowering the water pressure trays 17a and 17b. If the nozzle carry box 11 passes the end 4a or 4b of the cedar pillar 4, the nozzle A-1 , B-1 receives water pressure from saucer 1
7a, 17b, etc., are transmitted directly from the sensing signals A-3 and B-3 to the control function of the main body 1a through the H-shaped steel material 12, the nozzle carry box 11 is inverted, and the cedar pillar 4 is inverted. Can be automatically continued on the return path again.

The most effective operation method of the present invention is as follows.
The skin on the surface of the cedar pillar 4 is not rotated by the rotating rollers 8a and 8b, and the nozzle carry box 1
1 only sprays the rotary nozzle A-1 to roughly peel off the epidermis from the tip 4a to the root end portion 4b while peeling the banana, stop through the end portion 4b, and stop.
Is rotated intermittently to change the position, and then the returning operation is performed in the same manner as above to perform the skinning operation. This operation is performed until all the skin is peeled off. Next, while rotating the cedar pillar 4, the nozzle carry box 11 is slightly moved, and the cedar pillar 4 is peeled just like an apple, and the surface of the pillar is polished. .

These peeling methods are based on a rotating roller A-
1 and fixed roller B-1 to operate banana peeling, fixed roller B-1 only to use banana method, or rotate the pillar to operate apple peeling Whether or not to combine both methods to make a combination of the banana and apple peeling method, depending on the growth conditions of the skin on the surface of the cedar pillar 4, the operation is performed in various combinations, and when the regular rough peeling work is completed, The stripped state of the work surface
It is determined by a separately installed sensing device, and whether or not to shift to the finishing operation is automatically indicated to the operator, and the operation is continued.

When the finished cedar pillar 4 is used as a floor pillar, it is usually shipped in a separate process by inserting a back split 18 straight along the pillar. In the present invention, this step is also provided with a function of automatically processing.

FIG. 4 shows details of the apparatus. In FIG. 4, at the lower end of the cutter driving main body 20 of the spine split device,
Like the nozzle carry box 11, a roller box 16 equipped with slidable rollers 15 and the like is mounted along the square bar 3, and the drive main body 20 can run stably. Roller 26 along
a, 26b are also provided. These steel materials are not limited to the H type, and various types of steel materials may be used, and it is also optimal to use a stainless steel material, in which a water spout hole is formed in some places to prevent rust. A fixed rack 27 is mounted on the inner and lower surfaces of the H-shaped steel member 12, and the fixed rack 27 is installed so as to be able to reciprocate along the square bar 3 by a pinion 29 rotated by a drive motor 30 which is electronically controlled. .

On the upper surface of the drive main body 20, an arm 25 whose position can be adjusted left and right is mounted.
A vertical bracket in which a motor 23 for rotating a circular tooth cutter 21 for sawing the back split 18 is fixed, and an air cylinder type slide rod 24 that slides up and down without rotating is combined with a handle 32 for adjusting the minimum position of the cutting edge. 33 are integrally incorporated and formed.

In the back splitting work, first, the bottom of the circular tooth cutter 21 and the bottom position of the back split 18 to be cut are aligned with the cedar pillar 4b (root), and the adjusted position is used as the handle 3
Then, the back split 18 is formed while being sent from the cedar pillar 4b to the tip end 4a by the drive motor 30 by the pinion 29 and the fixed rack 27.

The circular tooth cutter 21 is provided with a detecting wire 22 at a position along the tooth surface of the circular tooth cutter 21 in order to automatically keep the cutting depth constant as the cutter advances, so as to constantly detect the cutting depth. Then, the sensing signal of the wire is sent to a computer, the drive motor 30 is controlled, and the feeding operation speed of the circular tooth cutter 21 is changed. Of course, data such as the thickness of the tip 4a, the thickness of the base 4b, and the total length of the cedar pillar 4 are input and the detection wire 2 is input.
The computer calculates the fluctuation value of the detection position 2 and
The height adjustment handle 32 can be adjusted while automatically adjusting the operating depth of the circular tooth cutter 21 by using a small motor (not shown).

Air is injected into the vertical slide rod 24 of the air cylinder type at a high pressure and has the same structure as that generally used as an air cushion buffer function.
In the case where a subtle jumping-up phenomenon of the circular tooth cutter 21 occurs due to the internal obstacle structure of the cedar pillar 4 during the back splitting operation, it plays a role of controlling the cutter operation. Of course, various functions such as a spring, a water pressure and the like can be used for these functions.

In the present invention, the cedar peeling device in which the spine splitting device is integrally mounted in the device is shown. However, the spine splitting device is usually removed, and after the skinning process is completed, the spine splitting device is mounted. Only this can be driven.

[0026]

Since the present invention is configured as described above, it has the following effects.

Since high-pressure water is sprayed from the lower surface of the cedar pillar, there is no difference in the spraying force applied to the cedar pillar even if the diameter of the cedar pillar is different and the height of the nozzle opening is not finely adjusted. Even
A constant stripping process can be performed at all times.

The peeling operation is performed by the sensor and the electronic control.
Since the peeling direction can be selected in accordance with the finished state of the surface and can be performed in various combinations, a uniform peeling operation can always be performed even by a non-skilled person.

The water injection nozzle is installed in a combination of a direct injection method and a rotary (turbo nozzle) method, and a higher variety and higher efficiency work can be performed than the conventional peeling operation using only the direct injection method. The work can be performed by selecting the nature of the work.

The conventional machine can be used only for peeling work, but by linking the back splitting function to the operation, anyone can continuously perform highly efficient work.

The greatest effect of the present invention is that the conventional machine performs work by injecting high pressure water from above into the cedar pillars, so that water or shavings scatter upwards, which bothers the worker. Since the invention sprays water from the lower part of the cedar pillar, it does not splash directly on the worker's face, so that the cedar peeling can be observed during work,
Waste material easily falls under the machine, so that even a layman can work efficiently without having to worry about waste material during work.

In the past, there was a case where the peeled waste skin accumulated under the machine, which made it difficult to work.
In particular, by erection of the lower square members 2, 3 in a diamond shape,
It is easy to run down with water, keeps the equipment normal, and is very suitable for clean factory installation.
