CONSTITUTION: A part of the auxiliary barking blades 11, 11' made of the wire brushes are faced to a wood barking vessel 1 from the slots 5, 5'. A rotor 2 is rotated by driving a motor M, the large pulleys P', P are rotated by the motors M', M" to rotate the driving shafts 13, 13', the driven sprockets 12, 12' are rotated by the rotation of the driving sprockets 14, 14', and the auxiliary barking blades 11, 11' are rotated. When the wood is charged into the wood barking vessel 1 in this stage, the wood is barked by the barking blade 3 of the rotor 2 while oscillated and tumbled from a lower part to an upper part by the rotor 2, and the last pellicle of the wood can be completely removed by the wire brushes when the almost barked wood is brought into contact with the auxiliary barking blades 11, 11'. Accordingly the last pellicle of the wood can be also completely removed.

Description

[Detailed Description of the Invention] <Industrial Application Field> This invention dramatically improves peeling ability, and
This is a wood peeling barker that reduces noise and photography as much as possible, and simplifies installation.In particular, it can cleanly peel down to the last thin layer of bark that is difficult to peel, and it removes unnecessary W from wood. This is to prevent it from getting attached.

<Prior art> Conventionally, an open part is provided at the bottom of a wood peeling tank, and a rotating body with a peeling blade is disposed in the longitudinal direction so as to face this open part, so that the wood is removed from the bottom to the top in the wood peeling tank. In the wood peeling barker, which performs the peeling by being swung to the
The wood input from the input section is oscillated by the rotating body and comes into contact with the peeling blade, thereby being peeled.

However, since the wood is only swung from below, the barking ability is inferior to that of conventional drum-type barkers, and to compensate for this, a method of installing an auxiliary rotating blade on the side plate has been considered. .

For example, Japanese Utility Model Publication No. 125103/1983
It is as shown in Japanese Patent No. 244501.

<Problems to be Solved by the Invention> However, even with this method, there is a drawback that the thin bark remaining at the end of the wood cannot be peeled off as neatly as compared to the drum-type barker. This is because the wood rubs against each other less than in a drum-type barker, and the thin bark does not peel off naturally.

Also, does the installation of a rotating blade improve the peeling ability?
There was a problem in that unnecessary cuts were made in the wood, resulting in fiber breakage.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the wood peeling barker according to the present invention has an opening formed at least at the bottom of the wood peeling tank, and the wood peeling barker is designed to face the opening. A rotary body equipped with a peeling blade is disposed below the wood peeling tank, and a part of the auxiliary peeling blade elastically supported inside the wood peeling tank faces through a long hole drilled in the side plate of the wood peeling tank. The structure is such that a rotary body swings and dances the wood from the bottom to the top while a peeling blade peels the wood, and the remaining thin skin is further removed from the roughly peeled wood using an auxiliary peeling blade, and this The rotating shaft is biased so that the finished body can be moved to prevent excessive force from acting on the wood.

Embodiment Next, an embodiment of the wood peeling barker according to the present invention will be described based on the drawings. 1 is a wood peeling tank that is open at the top and bottom, and 2 is a wood peeling tank that is opened at the bottom of the wood peeling tank 1. It is a long rotating body arranged in the longitudinal direction. Reference numeral 3 denotes a peeling blade disposed on the rotating body 2, and the peeling blade 3 has a desired shape such as a saw blade or a chip blade. The rotating body 2 is configured to be rotated in the direction of arrow a by a motor M that is decelerated in two stages via a chain C and a V-belt v. Reference numeral 4 designates a fixed side plate in which elongated holes 5, 5' are vertically bored at intervals in the longitudinal direction, and 6 is an openable/closable side plate disposed rotatably in the direction indicated by the arrow by a pivot shaft 7. In this way, the openable side plate 6
The reason for the rotatable structure is as follows: In the conventional wood peeling barker, as shown in Figure 2, in order to discharge the peeled wood, it is necessary to install the fixed type on both sides. A wood peeling tank with a plate a was installed with a slight inclination in the longitudinal direction, and discharged from the end in the long plane direction.
Even though there is a slight inclination, unlike a drum-type barker, the wood is only swung from the bottom to the top, so it does not move smoothly toward the wood ejecting section, and the wood may not be able to move smoothly on the way. Each time it got stuck, I had to stop the operation and remove the stuck wood, which was troublesome and inefficient. In addition, it is necessary to install a belt conveyor or the like to move the wood that is continuously discharged at the wood discharge section, which makes snowmaking a long process and requires a large snow-throwing area.
This was done in consideration of making it easy to discharge the wood from the wood peeling tank and reducing the area required for installing the equipment as much as possible. 8.8.degree. is a rotation shaft rotatably disposed on the support rods 9 and 9', respectively, outside the wood peeling tank. This support rod 9.degree. 9.degree. is arranged so as to be biased toward the stationary side plate 4 by a spring 10. As a result, the rotating shaft 8.8' is also biased toward the stationary side plate 4. 11.11' is this rotating shaft 8,8
' is an auxiliary skinning blade disposed at 11,
11° is made up of, for example, a wire brush or a tipped blade. In the illustrated example, a wire brush is used. As shown in the figure, a portion of this auxiliary peeling blade 11, 11' faces into the wood peeling tank 1 through the elongated hole 5.5°. On the other hand, a driven sprocket 12°12° is disposed at one end of each of the rotating shafts 8°8". Drive shafts 13.13
' is inserted through the driven sprocket 12.12°
Drive sprockets 14 and 14' are respectively disposed at positions corresponding to . And driven sprocket 12.1
2' and drive sprockets 14 and 14' are respectively connected by chains 15 and 15'. Drive shaft 13.
Large pulleys P and P' are arranged at one end of 13'.
■Connected to motors M' and M'' by belts v' and v''. That is, as the drive shaft 13 rotates, the drive sprocket 14 rotates, and the rotation shaft 8 is rotated by the driven sprocket 12 via the chain 15. Similarly, when the drive shaft 13 degrees rotates, the drive sprocket 14' rotates, and the driven sprocket 12' rotates the rotating shaft 8' through the chain 15 degrees. A skin collection gutter 1.6 is arranged in a curved manner below the rotating body 2, and this skin collection gutter 1.6 is arranged so that there is a slight gap between it and the peeling blade 3. .17 is rotating body 2
This is a pressurized discharge conveyor disposed at the lower side of the open/close side plate 6 side. That is, the pressure discharge conveyor 17 is arranged parallel to the pressure discharge side of the skin collection gutter 16 so that the skins collected in the skin collection gutter 16 fall. The reason why the skin collection gutter 16 is disposed in this way and the ash discharge ash bearer 17 is disposed as shown in the figure is as follows. In other words, as shown in FIG. 2, the conventional wood peeling barker has a collection plate d disposed below a rotating body C to collect the bark.
It was designed to be collected and moved by a pressure discharge conveyor e disposed below the rotating body C. However, in such a collection method, the angle of the collection plate d must be made steep to some extent in order to ensure that the skin that has fallen onto the collection plate d falls smoothly onto the pressurized discharge conveyor e. Since the pressure discharge conveyor e will be installed below, a considerable height will be required below the rotating body C, and as a result, the installation height of the wood peeling barker will be high, making installation cumbersome. At the same time, the wood feeding part f also becomes high, which has the disadvantage of making feeding work cumbersome. Conventionally, as a device to prevent the installation height of the wood peeling barker from becoming too high, it was installed on the ground. A concave groove is constructed, and the pressure discharge conveyor e is placed inside this groove.
This was to solve the problem of the inconvenience of having to carry out the construction, which of course increases the construction cost.

However, the motor M is driven to rotate the V-belt V and the chain ci to rotate the rotating body 2, and the motors M' and M'' rotate the belts v' and v''. The large pulleys P', P rotate, thereby rotating the drive shaft 13.13' and each drive sprocket 14.14.
15.degree. rotates, each driven sprocket 12, 12.degree. is rotated via the chain 15.15.degree., and the respective auxiliary peeling blades 11,11' are rotated. At this stage, the wood is put into the wood peeling tank 1. Then, the wood is swung and danced from below to above by the rotating body 2, and is subjected to a peeling action by the peeling blade 3 of the rotating body 2.

Then, the roughly debarked wood is auxiliary debarking blade 11,11°
When in contact with the wood, the wire brush removes the last thin skin of the wood so that it is polished clean. In addition, if the wood collides strongly with the auxiliary peeling blade 11.11°, the rotating shaft 8.8' can be rotated by the spring 10, so the auxiliary peeling blade 11.11' has a long hole. 5, 5' to move out of the fixed side plate 4 to avoid unnecessary damage to the wood.

Further, each rotating shaft 8,8' is connected to an independent support rod 9'.
Since the auxiliary peeling blades 1] and 11' are attached to the auxiliary peeling blades 9' and biased by the spring 1o, they can also be moved individually, and those that collide strongly can release the force of the collision.

Further, the skin peeled by the peeling blade 3° of the rotary body 2 falls into the skin collection gutter 6 from the gap between the rotary body 2 and the wood peeling tank 1. Then, the skin on the skin collection gutter 16 is scraped out by the peeling blade 3 by the rotation of the rotating body 2, falls onto the pressure discharge conveyor 17, and is moved and discharged to the outside of the wood peeling barker. When the peeling is completed, all operations are stopped, the retractable side plate 6 is rotated to a horizontal position, and the wood is taken out using a forklift or the like.

<Effects of the Invention> As described above, according to the wood peeling barker according to the present invention, an opening is formed at least at the bottom of the wood peeling tank,
A rotary body equipped with a peeling blade is arranged below facing this opening, and an auxiliary peeling blade is elastically supported inside the wood peeling tank through a long hole drilled in the side plate of the wood peeling tank. Since it is configured so that a part of the wood is exposed, it is possible to cleanly remove even the last thin layer of wood, and if excessive force is applied to the auxiliary peeling blade, the rotation axis can be moved to reduce the force. This has the effect of creating a relief hole and eliminating the need to form unnecessary cuts on the wood.
