Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wood debarking machine used for debarking in a pre-process of manufacturing wood chips, debarking of construction wood, and the like.

(Prior Art) As a conventional wood peeling machine of this kind, there is one disclosed in Japanese Patent Publication No. 5764/1983, for example.

This wood debarking machine has an opening formed at the bottom of a debarking tank that accommodates wood, a rotary body disposed below the debarking tank so as to close the opening, and a large number of debarking blades on the outer circumferential surface of the rotary body. The wood put into the peeling tank is peeled by the peeling blade of the rotary body that is rotated, and the wood is discharged from the outlet at the end of the peeling tank, and the bark is placed from the opening below the rotary body. The bark is arranged to fall onto the conveyor.

(Problems to be Solved by the Invention) In the above-mentioned prior art, the peeling blade provided on the rotating body hits the wood in the peeling tank in stages, so
The wood is peeled while rolling. Incidentally, the wood is input from the input port and then rotated toward the discharge port, but it stays at the input location and is difficult to move smoothly toward the discharge port. On the other hand, as the wood rotates, the skin is sequentially peeled off while forming circumferential grooves on the outer surface of the skin using a peeling blade. The movement to the wood is not carried out smoothly, and the subsequent peeling blade hits and bites into the same spot, damaging the woody part of the wood. Therefore, there are problems such as material loss and quality deterioration of the wood parts, non-uniform peeling, and reduced peeling efficiency.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to prevent material loss and deterioration of quality of the woody part of wood, and to enable uniform peeling and improve the peeling efficiency. We offer wood stripping machines.

(Means for Solving the Problems) In order to achieve the above object, the present invention has taken the following technical means.

That is, the invention according to claim 1 is characterized in that a peeling tank for storing wood is formed by a pair of left and right side plates, a wood input port is formed at one longitudinal end of the peeling tank, and a wood input port is formed at the other end of the peeling tank. A wood discharge port is formed at the bottom of the peeling tank, an opening is formed between a pair of left and right side plates at the bottom of the peeling tank, and a rotating body is disposed below the peeling tank so as to close the opening. In the wood peeling machine, a plurality of first peeling blades are provided on the outer peripheral surface of the rotating body, and the first peeling blades of the rotating body peel off the bark of the wood in the peeling tank. A small-diameter rotor is disposed on an axis substantially perpendicular to the axis of the rotating body and is forcibly driven to feed the wood toward the wood discharge port. This is due to the fact that it has a two-layered blade.

The invention set forth in claim 2 is characterized in that, in addition to the configuration set forth in claim 1, the rotor further comprises:
It penetrates the peeling tank and is pivoted at an angle with respect to the horizontal plane.

The invention set forth in claim 3 is characterized in that, in addition to the configuration set forth in claim 1, the rotor further comprises:
It is located at a position slightly shifted from the wood input port to the wood discharge port side of the peeling tank.

The invention set forth in claim 4 is characterized in that, in addition to the structure set forth in claim 1, the lower end portions of the pair of left and right side plates are connected to each other by connecting plates arranged at a predetermined interval in the longitudinal direction. A third skinning blade is provided on the upper surface of the connecting plate, and the rotor is disposed between the connecting plates.

(Function) According to the invention described in claim 1, wood is charged into the peeling tank from the wood input port of the peeling tank. As the rotary body rotates, the loaded wood is sequentially hit by a large number of first peeling blades, so that the wood peeling process progresses while rotating in a constant direction, and the wood is sequentially transferred toward the wood discharge port.

At this time, by rotationally driving a rotor disposed on an axis substantially orthogonal to the axis of the rotating body, the wood is forcibly sent to the wood discharge port side by the second peeling blade.

Therefore, accumulation of wood near the input port is prevented.

Moreover, by rotating the first skinning blade and the second skinning blade in mutually orthogonal directions, a peeling force is applied in the axial direction and the circumferential direction of the wood, making the peeling more efficient.

According to the invention according to claim 2, the rotor comprises:
Since it penetrates the peeling tank and is pivoted in an inclined manner with respect to the horizontal plane, it promotes rolling of the wood toward one side plate and allows the first peeling blade to be applied to the entire outer periphery of the wood. can.

According to the invention according to claim 3, the rotor comprises:
Since it is provided at a position slightly shifted toward the discharge port from the wood input port of the peeling tank, the wood remaining near the wood input port can be smoothly moved toward the wood discharge port.

According to the invention set forth in claim 4, the lower ends of the pair of left and right side plates are connected to each other by connecting plates arranged at a predetermined interval in the longitudinal direction, so that widening of the opening is prevented and Since the third peeling blade is provided on the upper surface of the connecting plate, the third peeling blade also performs peeling, which is effective. The resistance in the feed direction generated by the third peeling blade is reduced by the rotation of the rotor disposed between the connecting plates, and prevents the wood from moving toward the discharge port.
