Description

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

(Prior Art) Various kinds of wood barking barkers have been proposed in the past, and one example is the one disclosed in Japanese Patent Publication No. 61-46282. This barker has an opening connected along the longitudinal direction at the bottom of a hopper for storing wood, and one side of the opening is composed of a receiving side plate and the other side is a feeding side plate. The side plate is erected in the vertical direction with the lower part curved inward toward the opening.
The feed side plate is formed such that a lower portion thereof is inclined inward toward the opening. A large number of step-block-shaped stripping blades are protruded from the outer circumferential surface of the pipe shaft at intervals in the circumferential and axial directions, and a stripping rotor whose upper part rotates from the feeding side plate to the receiving side plate is mounted on the upper part of the pipe shaft. is inserted so as to close the opening, and the hopper is arranged obliquely along the longitudinal direction, with the sloping upper end serving as a lumber input part and the lower end serving as a wood takeout part. The structure is such that the wood is conveyed continuously in the longitudinal direction while being transferred inside the hopper to peel the wood.

In addition, as another example of a wood peeling barker, long holes in the vertical direction are bored at desired intervals along the longitudinal direction of the side plate of a wood peeling tank formed in a V-shaped cross section. A rotary blade that protrudes from the outside to the inside of the wood peeling tank via the hole is formed in the shape of a blue dragon blade, and is arranged along the longitudinal direction of the wood peeling tank outside the side plate in which the elongated hole is bored. There is one in which the same number of elongated holes are provided on a long rotating shaft (see Japanese Patent Laid-Open No. 16804/1983).

(Problems to be Solved by the Invention) In the prior art described above, in the former case, the opening at the bottom of the hopper is a continuous large opening spanning the entire length in the horizontal direction, so the weight of the wood is directly applied to the pipe shaft.
A considerable amount of rotational force is required and the power cost is high, and when the ends of the wood collide, the pipe shaft is dented and deformed, contacting the opening and causing noise, and furthermore, the peeling blade protruding from the pipe shaft is distorted. The edge of the opening abuts the opening, and the edge of the opening expands outward, forming a
There are problems such as the toothed portion also being deformed and the pipe shaft not rotating smoothly.

In addition, even in the latter conventional technology, the discharge hole located at the bottom of the wood peeling tank is provided along the entire length of the tank in the longitudinal direction, and there is also a long hole through which the rotary blade enters and exits. When transferred and collides with the side plate, it is easily deformed.
There is a problem that smooth rotation of the rotary blade is hindered.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and the first feature of the invention is that the bottom of the wood peeling tank 1 has a A plurality of openings 6 are provided at predetermined intervals along the direction and across the arc-shaped connecting portion 5 of a predetermined width, and a large number of peeling blades 17 are provided on the outer peripheral surface in the circumferential and axial directions corresponding to the openings 6. Peeling rotary tube shafts 16 protruding at predetermined intervals are attached so that their axes run along the longitudinal direction of the wood peeling tank 1 and their upper portions close the openings 6. The arc-shaped connecting portion 5 has an inner radius of curvature larger than the outer peripheral surface radius of the peeling rotary tube shaft 16, and the peeling rotary tube shaft 1
6 is aligned with the center axis of curvature of the connecting portion 5.

Further, the second invention is characterized in that a plurality of peeling blades 32 are provided protruding from the upper surface of the arc-shaped connecting portion 5 in the wood peeling barker of the first invention.

(Function) According to the above structure of the present invention, since the opening 6 is provided at the bottom of the wood peeling tank 1 with the connecting portion 5 interposed therebetween, the connecting portion 5 prevents the outward expansion of both side plates of the bottom. In addition to preventing and reinforcing the structure, the wood support also serves as a part to support the weight of the wood and prevent each end of the wood from colliding directly with the peeling rotary tube shaft 16. Therefore, there is little deformation of the edge of the opening 6 and there is no concave deformation of the peeling rotary tube shaft 16, so that the peeling rotary tube shaft 16 can continue to rotate smoothly.

Furthermore, the peeling blade 32 provided on the upper surface of the arc-shaped connecting part 5 supports the wood being transferred and simultaneously peels off the outer skin of the wood, thereby performing an auxiliary peeling action and improving the peeling work efficiency.

(Example) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In the drawings, reference numeral 1 denotes a wood peeling tank, which has a rectangular shape when viewed from above and is fixed directly or via a member 4 to a support 3 erected on a base 2. A plurality of openings 6 are provided at the bottom of the wood peeling tank 1 at predetermined intervals along its longitudinal direction, sandwiching an upwardly convex arc-shaped connection portion 5 of a predetermined width, and each opening 6 The bottom plate of one example is inclined (or curved) from the lower end of the side plate IA downward inward to form the wood feeding bottom plate 7, and the bottom plate on the other side of each opening 6 is the side plate IB.
It is curved inwardly and downwardly from the lower end to form a wood transfer/reversal bottom plate 8. These bottom plates 7°8 are connected to diagonal members 9.
, 10, which extend in the longitudinal direction and are supported by support beams 11 and 12 extending in the longitudinal direction, are tilted at a predetermined angle, and one high end serves as the lumber supply section 13, and the other low end serves as the wood supply section 13, and the other low end is the wood supply section 13. A shutter 15 is provided at the end of the wood discharge section 14 so as to be movable up and down.

Reference numeral 16 denotes a rotary peeling tube shaft, on the outer circumferential surface of which a large number of peeling blades 17 having stepped blade portions are protruded at regular intervals at a predetermined angle in the circumferential direction and at predetermined equal intervals in the axial direction. .

The arcuate connecting portion 5 has an inner radius of curvature slightly larger than the radius of the outer peripheral surface of the peeling rotary tube shaft 16, and has a length corresponding to about one-fourth of the outer circumference of the tube shaft 16. , furthermore, the arc center axis is inclined at the same angle as the inclination angle of the base i7.8.

The peeling rotary tube shaft 16 has a support girder 18 suspended over the base 2 so that its center axis coincides with the arcuate center axis of the connecting portion 5 and the upper portion of the tube shaft closes the opening 6. To,
The shaft ends 21.22 are journalled via bearings 19, 20. A Cheno wheel 23 is wedged on one shaft end 21 of the tube shaft 16, and an endless Cheno wheel 26 is wound between it and a drive Cheno wheel 25 wedged on the output shaft of a motor 24.

At the edges of the openings 6 of the bottom plates 7 and 8, there are comb-shaped notches 27 which have the same pitch as the peeling blades 17 and have a width wider than the peeling blades 17, and which the peeling blades 17 do not come into contact with. It is formed.

Note that the width of the connecting portion 5 is made equal to the width between the notches 27. This is because the axial pitch of the peeling blades 17 is set at equal intervals, but if necessary, the pitch of the peeling blades 17 may be adjusted to correspond to the width of the connecting portion 5 only in the portion where the connecting portion 5 is located. It can be increased or decreased by

28 is a hopper provided below the peeling rotary tube shaft 16;
A conveyor 29 is provided below the hopper 28 and carries the bark peeled off from the wood W to the outside of the barker. A chute 131 disposed in front of the shutter 15 of the discharge section 14 is a conveyor for carrying out the wood from which the bark has been peeled off.

A plurality of peeling blades 32 are protruded from the upper surface of the connecting portion 5, and perform an auxiliary peeling action.The number, size, etc. of these blades can be set arbitrarily. It also serves as reinforcement.

In addition, the connecting portion 5 is molded separately from both bottom plates 7 and 8,
Its thickness, shape, etc. should be selected to be sufficiently strong in terms of strength, and care must be taken to prevent it from coming into contact with the peeling rotary tube shaft 16.

According to the above-described embodiment of the present invention, when the motor 24 is started, power is transmitted to the peeling rotary tube shaft 16 via the Cheno wheel 25, the endless Cheno wheel 26, and the Cheno wheel 23, and this tube shaft 16 is connected to the first Rotate in the direction shown by arrow A in the figure. Therefore, when the wood W is sequentially fed into the wood peeling tank 1 from the supply section 13, the wood W is rotated and peeled inside the wood peeling tank 1, which is arranged at an inclination, due to the rotation of the peeling rotary tube shaft 16. is peeled off by the peeling blades 17 and 32 and moved to the discharge section 14. The wood W being peeled and transported is transferred and lowered by its own weight on the lumber supply bottom plate 7 provided at an inclination, and the peeling blade 1 protruding from the conveyance and distribution peeling rotary tube shaft 16

The bark is peeled off while being supported by the wood, and the receiver is stopped by the wood transfer/inversion bottom plate 8 and reversed, and rotates in the direction of the arrow opposite to the direction of rotation of the peeling rotary tube shaft 16.

In this way, the wood W is sequentially moved to the discharge section 14 while being transferred within the peeling tank 1, and the wood W accumulated in the discharge section 14 is further peeled while continuing to rotate. is opened, the wood W is dropped from the chute 30, and is sent onto the carry-out conveyor 31, where it is continuously stripped.

On the other hand, as the peeling rotary tube shaft 16 rotates, the wood bark peeled off by this peeling operation is transferred to a conveyor 29 disposed below.
It falls on top and automatically 11 outside Barker one after another! ! Served.

Most of the wood W during the peeling process is supported by the connection part 5, and the auxiliary action of the peeling blade 32 makes it easy to peel the bark and increases the peeling efficiency. In addition to being prevented from colliding with the rotary tube shaft 16 and being deformed by denting, the deformation of the comb tooth-missing portion 27 is also reduced.

In this embodiment, the bottom plates 7 and 8 include both side plates IA and 1.
It can be an extension of B, and it can also be used as a side plate and a bottom plate, for example, the side plate and the bottom plate can be an integrated inclined plate or a curved plate. Considering the curvature, damage or wear of the skinning blade 32, the skinning blade 32.1 may be replaceable.
? It is also possible to make only one part replaceable. Note that the opening 6
The comb-like notches 27 on the edge of the bottom plate may be divided into a plurality of parts and may be replaced.

(Effects of the Invention) As described above, in the wood peeling barker according to the present invention, the bottom opening 6 of the wood peeling tank 1 is provided with the arc-shaped connecting portion 5 interposed therebetween, so that the opening 6 is reinforced. In addition to preventing deformation of the periphery of the opening 6, since the wood is supported by the arc-shaped connecting portion 5, the weight of the wood is not directly applied to the peeling rotary tube shaft 16, and furthermore, dents and deformation due to collisions of the ends of the wood are prevented. Therefore, not only can the smooth rotation of the peeling rotary tube shaft 16 be maintained, but also the power cost can be reduced by reducing the power required. In addition, since a plurality of peeling blades 32 are provided protrudingly on the upper surface of the arc-shaped connecting portion 5, the peeling work is effectively promoted by an auxiliary peeling action, and the work efficiency is improved by shortening the peeling work time. Cost can be reduced. Furthermore, the existence of the arc-shaped connecting portion 5 suppresses the wood from scattering in the barking tank 1, and the noise and vibration generated during the barking process are extremely low, and damage is also minimal, so the lifespan of the barker can be extended. .
