Description

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

In the past, the most common type of barker used for stripping wood was a rotating drum type.

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.

In other words, the pieces of wood thrown into the drum repeatedly collide and rub against each other as they dance around inside the rotating drum, and the skin is peeled off.

Therefore, in such conventional drum-shaped barkers, the wood to be fed must be cut into short pieces in order to facilitate the wild dancing. Not only did it have to be reduced to about 1 to 1.5 degrees, but because the wood repeatedly danced violently inside the drum, the sound and vibrations generated during the work were intense.

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

In addition, as mentioned above, a strong vibration occurs, so in order to install this device, a firm foundation must be constructed, which is not only costly but also makes it easy to move the device. It also had the disadvantage of not being able to do so.

Therefore, in the present invention, a plurality of elongated holes arranged in parallel are bored in the bottom of a long semi-cylindrical bar cover body installed diagonally, and a rotating disk is inserted into the bar cover so that it faces into the bar cover body through the long holes. A comb tooth-like arm is provided outside the barker body, and a comb-like arm is provided inside the barker body to rotate in the transverse direction of the barker body, and a protrusion is provided in the transverse direction of the inner circumferential surface of the barker body. In addition, a chip-shaped blade is provided on each of the rotating disc, the arm, and the protrusion, so that the outer skin of the wood is arranged on the rotating disc, the arm, and the protrusion, instead of a method in which the pieces of wood collide with each other. This was developed with the aim of providing a wood peeling barker that uses a chip-shaped blade to peel the wood, reduces noise and vibration as much as possible, and as a result does not require a special foundation for installation.

Now, an embodiment of the wood peeling barker according to the present invention will be described based on the drawings. 1 is a long semi-cylindrical barker body installed diagonally, and 2 is a barker at the bottom of the barker body 1. These are multiple long holes drilled in parallel.

3 is a pulley of the motor M, and 4 is a pulley disposed on the rotating shaft 5.

These pulleys 34 are connected to each other by a belt 6, and a plurality of rotating discs 7 are arranged on the rotating shaft 5 at regular intervals.

This rotating disk 7 is arranged so as to face the inside of the bar car body 1 from the bottom of the bar car body 1 from below through the elongated hole 2 bored in the bottom of the bar car body 1. Although only one rotating shaft 5 may be provided, as shown in the figure, two or more rotating shafts may be provided.

Reference numeral 8 denotes a rotation shaft disposed inside the bar car body 1 in the longitudinal direction of the bar car body 1, and a plurality of arms 9 are fixed to the rotation shaft 8 in a downward comb shape. It is.

The rotation shaft 8 does not rotate 360 degrees, but reciprocates through a fixed angle, for example, about 120 degrees.The following means is used for this purpose.

That is, in the figure, 10 is a connecting arm fixed to one end of the rotating shaft 8, and 11 is a bar connected to the other end of this connecting arm 10 via a pin 12.

Reference numeral 13 denotes a rotating ring connected to the other end of the bar 11 via a pin 1z.
It meshes with a small gear 15' disposed at 4'.

Further, a pulley 16 is further disposed on the rotating shaft 14', and this pulley 16 is connected to the pulley 16 of the motor M'.
' and are connected by a belt 17.

This motor M' may be the same as the motor M described above, or a separate motor may be used as shown.

However, when the lever motor M' is driven, the belt 1
7 rotates the rotating shaft 14'14, and further rotates the rotating wheel 1.
3 also rotates.

Then, the end of the bar 11 on the rotating wheel 13 side performs a rotational motion, but the end on the rotating shaft 8 side performs a reciprocating motion, so that the rotating shaft 8 ends up reciprocating.

Next, reference numeral 18 in the figure is a protrusion provided in the transverse direction of the inner circumferential surface of the barker main body 1, and reference numeral 19 is a protrusion 18, and a chip-shaped blade provided on the rotary disk 7 and the arm 9, respectively. It is.

Thus, the motors M and M' are driven.

Then, the rotating shaft 5 is rotated by the motor M, and the rotating disk 7 is rotated.

Next, as the motor M' rotates, the rotation shaft 8 rotates as described above, and the arm 9 reciprocates at a constant angle.

Therefore, when a piece of wood with bark is put into this barker body 1, this wood is moved inside the barker body 1 along the inner circumferential surface of the barker body 1 by the rotating arm 9. The movement is repeated in the transverse direction of 1.

In this process, the wood comes into contact with chip-shaped blades 19 provided on each of the arm 9, rotating disc 7, and protrusion 18, and is stripped of its skin.

Furthermore, as this action is repeated, the wood gradually moves downward due to the fact that the barker main body 1 is completely installed at an angle, and at the time it moves downward, the peeling action is complete. It will be terminated in .

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 the installation of the entire device, and therefore the installation is easy. Not only that, but it also has the effect of being able to be easily removed and moved.
