Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood peeling barker that reduces noise and vibration as much as possible, is easy to install, and is easy to manufacture, maintain and inspect.

Traditionally, the barker-rotating drum type used for barking wood has been the most common.

That is, a piece of wood with the skin attached is placed into a rotating cylindrical drum, and as the drum rotates, the wood is lifted upward along the inner circumferential surface of the drum, and when it falls, the wood collides with other pieces of wood. In addition, the peeling action is performed by rubbing together.

The pieces of wood thrown in are thrown into the rotating drum, colliding with each other, grinding against each other, and peeling off the bark.

Therefore, in such a conventional drum-shaped barker, the wood to be fed must be cut into short lengths in order to facilitate the wild dancing. Not only did the length have to be about 1.5 m, but the wood repeatedly danced violently inside the drum, resulting in heavy noise and vibration during the work.

As noise regulations have become stricter, the places where they can be used have become extremely limited.

In addition, as strong vibrations are generated as mentioned above, a solid foundation must be built in order to install this equipment, which not only increases the cost of building the foundation but also makes it difficult to easily move the equipment. It also had some disadvantages, such as being unable to do so.

There is still a method of debarking using a debarking hammer without rotating a cylindrical drum, as disclosed in Japanese Unexamined Patent Publication No. 55-51509.

However, this type requires a hole in the cylindrical drum for the debarking hammer to enter, which is cumbersome to manufacture.Also, since the cylindrical drum does not rotate, the wood is blocked by the debarking hammer and the hole in the inlet path and cannot be inserted into the rotating drum. The drawback is that it may get caught, and in that case, the work of removing the wood is troublesome.

In other words, in the case of a wood peeling barker that does not rotate a cylindrical drum, the wood peeling tank does not need to be of a cylindrical type; it may be of a type that is easy to manufacture, and it is easy to remove stuck wood. It is preferable that the upper part of the wood peeling tank is open.

In view of this, the present invention has been proposed by providing long holes in the vertical direction at desired intervals along the longitudinal direction of the side plate of a wood peeling tank formed in a V-shaped cross section, and passing through the long holes to the wood peeling tank. A rotary blade that protrudes and retracts from the outside to the inside is arranged, and the rotary blade is formed into a blue dragon blade shape, and this is installed along the longitudinal direction of the wood peeling tank on the outside of the side plate in which the elongated hole is bored. The rotary blade is rotated by arranging the same number of long holes as the number of elongated holes on a long rotary shaft arranged at This enables the peeling action to be performed while moving the wood, and a long high-speed rotating blade shaft is disposed in the upper longitudinal direction of the wood peeling tank, so that the high-speed rotating blade shaft facilitates the peeling action. It was developed with the aim of providing a highly durable wood peeling barker that is easy to manufacture, reduces noise and vibration as much as possible, and, as a result, does not require a special base for installation. be.

Next, an embodiment of the wood peeling barker according to the present invention will be described based on the drawings. 1 indicates a rectangular side plate 2. This is a wood peeling tank with a V-shaped cross section, with z facing each other.

Since the side plates 2, 2' can be flat plates, they are easier to manufacture than those using cylindrical drums.

A discharge hole 3 for discharging the bark is formed at the bottom of the wood peeling tank 1, and a conveyor 4 for transporting the bark is provided below the discharge hole 3.
It is arranged.

Reference numeral 5 indicates elongated holes vertically bored in the side plate 2 at desired intervals along the longitudinal direction of the wood peeling tank 1, and 6 indicates longitudinal holes of the wood peeling tank 1 on the outside of the side plate 2. It is a long rotating shaft arranged along the direction.

Since the side plate 2 is a flat plate, the work of drilling the long holes 5 can be done easily.

The rotating shaft 6 has a pulley 7 and a belt 8 disposed at its end.
The rotary shaft 6 is connected to the drive motor 9 via the rotary shaft 6.

Reference numeral 10 denotes a rotary blade which is fixed to the rotary shaft 6 and extends from the outside to the inside of the wood peeling tank 1 via the long hole 5, and this rotary blade 10 is used to peel the wood. As mentioned above, any blade that comes into contact with the wood in the wood peeling tank 1 is sufficient, but in order to reduce the resistance when it comes into contact with the wood, it is formed into the shape of a blue dragon blade as shown in the figure, and the blade is not used for peeling the wood. The saw blade is used to ensure that the

Moreover, since this rotary blade 10 itself also promotes the movement of wood, the angle at which it is arranged with respect to the rotary shaft 6 is sequentially shifted out of phase.

However, if the rotary blade 6 is formed into a spiral shape (screw blade shape), it is more effective to promote movement.

Reference numeral 11 denotes a high-speed rotating knife shaft which has a peeling blade 12 on its surface and is disposed in the upper longitudinal direction of the wood peeling tank 1. A pulley 13 is disposed at one end of this knife shaft 11, and and is connected to the motor 15.

The motors 9 and 15 are then driven to rotate the rotary blade 10 and the rotary blade shaft 11.

When the wood is put into the wood peeling tank 1, the wood is scooped upward by the rotation of the rotary blade 10, and by repeating this process, it is subjected to the peeling action.

This causes a temporary peeling effect, but if this is not enough, the wood that is scooped upward will
Eventually, the remaining material will come into contact with the rotary cutter shaft 11 rotating above and be peeled off.

In addition, if the rotary blade 10 is arranged at a different angle from the rotation axis 6, the state of the wood scooped up by the rotary blade 10 will be reversed up and down at the front and back, like a seesaw. Therefore, the wood will be moved sequentially.

Rotating blade 10 over the entire length of the wood by moving
and the rotary knife shaft 11 will act.

The peeled skin then falls downward along the side plates 2, 2', is transferred from the discharge hole 3 onto the conveyor 4, and is conveyed to the destination.

All you have to do is take out the wood once the barking is complete.

If wood is still caught in the long hole 5 or rotary blade 10 of the wood peeling tank 1, the upper part of the wood peeling tank 1 is open, so the caught wood can be easily removed. .

As mentioned above, the wood debarking barker of the present invention does not debark by colliding wood with another wood like the conventional drum-type barker, but also does not debark by the method in which the wood is peeled while dancing up and down. Therefore, the noise and vibration generated during the debarking process are much smaller than those of the conventional methods mentioned above, and since the vibrations are small, there is no need to construct a special foundation for installing the entire device. Not only can it be installed, but it can also be easily removed and moved, and since the wood peeling tank is V-shaped, it has the advantage of being easier to manufacture than a cylindrical drum type. It is.
