Description

[Detailed description of the invention] This invention relates to drum bar force, and more specifically, a rotary cutter is provided outside the drum, and the cutter is forced into the line through the gap of the drum and rotated forcibly to remove the bark from the tree. The present invention relates to an improvement in drum bar force that can be effectively carried out.

In the production of chips, the drum bar force used to remove the bark of pine and other chip logs is such that, as described in Japanese Patent Publication No. 4528528, for example, the drum bar force is applied to the center of the edge body at equal pitches on one side of the edge body into which the logs are placed. A cut portion is provided up to the vicinity, the edge body is placed horizontally with the cut portion positioned below, and a mounting portion is attached to a rotating shaft placed horizontally below the edge body at the same pitch as the pitch of the cut portion. A beating body is rotatably attached to the wire ball by a pivot, and the chipping body placed in the wire ball is rotated from the cut portion with the rotation of the rotating shaft, and the chipping member enters into the wire ball and removes the raw wood. A drum bar force has been proposed that causes the bark to be stripped by hitting it.

However, with such a configuration, when the tapping member hits the raw wood, it rotates around the pivot due to the reaction and violently hits the cushioning rubber provided on the mounting part, which may cause the hitting member to break or bend. In addition, there are drawbacks such as large noise and poor peeling efficiency due to its structure.

This invention aims to eliminate the above-mentioned drawbacks of the conventional technology, and its feature is that a plurality of edges are connected to the machine frame on a support body through at least two supporting/rotating mechanisms. Arranged in series with a certain gap between adjacent contracted bodies,
A support with an uneven surface is installed inside these wire spheres, and a connecting rod with an uneven surface that connects multiple linear bodies is installed on this support. Alternatively, a disc upper blade vine pivotally attached to an arm provided so as to be swingable from side to side is arranged so as to be forcibly rotated, and the cutter is plunged into the wire sphere through the gap between the wire bodies to rotate the edge body. The present invention provides a drum bar force with high peeling efficiency, which is configured to peel the bark by hitting the log moving with the movement of the log.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 is an external view of the drum bar force of this invention. This drum bar force is rotatably supported by a plurality of guide roller mechanisms 3 disposed on a machine frame 2 attached to a support 1, and is a power transmission mechanism. 4, and a rotary cutter section 6 disposed on the support body 1 at a gap position previously provided between the wire spheres. There is.

The guide roller mechanism 3 described above is one of a plurality of linear bodies 51a to 51e that are attached to a machine frame 2 attached to a support 1 and constitute a detached body 5, as shown in FIGS. 1 and 2. , a guide roller 31 in contact with the plate-shaped rail bodies 52 a to 52 d attached to the outer periphery of the linear bodies 51 a, 51 b, and 51 e, and a bearing 32 that pivotally supports the roller.
It is made up of.

As shown in FIG. 2, the power transmission mechanism 4 includes a motor 41 mounted on the machine frame 2, a reduction mechanism 42, a pulley 43 of the motor, and a pulley 44 of the reduction mechanism. A bell hung between pulleys 53 a and 53 b attached to the whole can 51 a and 51 b) 45
．． It consists of 46.

As shown in FIG. 1, FIG. 2, and FIG. 4, the separation body 5 has linear bodies 51b to 51e each having an abutment 53 formed with unevenness on the inner periphery of the line in order to increase the peeling effect outward. It is divided into a plurality of equal parts, and a plurality of them are attached regardless of the length of the can, and in this embodiment, four linear bodies 51 b to 51 e are placed on this support as one body with a constant gap a between adjacent mold release bodies. The connection rod 54, which is connected to the connecting rod 54 and has a concavo-convex shape on its periphery, is substantially composed of two linear bodies together with a linear body 51a having a notch 9 on its inner circumferential surface (not shown).

As shown in FIGS. 1 to 3, the rotary cutter section 6 has one end pivotably supported by a motor 61 mounted on the machine frame 2 and a bearing stand 62 similarly mounted on the machine frame. A pair of arms 64a each having a disc-shaped cutter 63 with a protrusion on its circumferential surface attached rotatably around a pivot at its end.
, 64 b, a belt 65 that is hung between the pulley attached to the shaft on which the cutter is attached and the boot of the motor, and a pair of springs that are attached to the machine frame 2 together with the bearing holder before and after the bearing holder. It is comprised of an elastic member 68 attached between the attachment plates 66a, 66b and an attachment rod 67 attached to the center of the arms and drawn to the sides of the two attachment plates of the arms 64a, 64b.

This rotary cutter section 6 has linear bodies 51a and 51
between 51 b and 51 C, between 51C and 51
As shown in FIG. 2, the arms 64a, 64
The cutter is attached so that a part of the cutter protrudes into the inside of the wire body through the gap a between adjacent wire spheres when b is at rest.

Although not shown, the cutter 63 of this rotary cutter section 6
Alternatively, one end of the arms 64a, 64b or the spring mounting plates 66a, 66b may be installed so that the other ends of the arms 64a, 64b do not collide with the outer surfaces of the linear bodies 51a to 51e or the connecting rod 54 even when the arms swing at their maximum. A stopper is provided which abuts the arm with a cushioning material.

Further, the elastic member 68 allows the arm to stand on its own due to its elasticity, and when an excessive impact is applied to the cutter 63 by the raw wood, the repulsion can be absorbed by the elasticity of the member.

In the figure, 7 is a hopper attached to the machine frame 2 in contact with the end of the linear body 51e, and 8 is a hopper into which logs are fed, and 8 is the linear body 51a.
This is a chute for taking out logs from which the bark has been peeled, which is attached to the machine frame 2 in contact with the end of the log.

The drum bar force of this invention has the above-mentioned structure, and the procedure for peeling the bark of a chip log using this drum bar force will be explained below.

First, the linear bodies 511 to 51 are integrated by a connecting mechanism consisting of the linear body 51a, the abutment 53, and the connecting rod 54.
At the same time, the motor 61 of the rotary cutter section 6 is energized, and the motor rotates the cutter 63 in the opposite direction to the rotating direction of the detached body. Rotate it in the direction of.

The chip raw wood W put into the linear body 51e from the hopper 7 is lifted in the rotating direction of the linear body by the support 53 and the connecting rod 54 as shown in FIG. The bark is peeled off by these unevenness and protrusions when it comes into contact with the cutter 63 of the rotary cutter part 6 that protrudes into the mold release body from a, or is pressed against the abutment or the connecting rod.

In particular, in the rotary cutter section 6, the arms 64a and 64b swing due to the collision between the raw wood W and the cutter 63, and together with the scratching of the bark due to the rotation of the cutter, the bark is struck, thereby amplifying the peeling action.

The log W is subjected to such action multiple times while moving from the linear body 51e to the direction 51a, and when the log W is discharged from the chute 8, the bark is almost completely peeled off.

Further, the bark peeled off by this peeling operation is discharged outward through the gap provided between the mold release bodies.

As described above, this invention arranges a plurality of line images in series with a fixed gap between adjacent line spheres via at least two support/rotation mechanisms with respect to the machine frame on the support. A support base with an uneven surface is installed inside these wire spheres, and a connecting rod with an uneven surface that connects a plurality of linear bodies is installed on this support base, and a connecting rod with an uneven surface that connects a plurality of linear bodies is attached to the outside of the adjacent linear bodies. A disc-shaped cutter pivotably mounted on an arm that is swingable up and down or left and right by a spring is arranged so as to be forced to rotate, and the cutter is plunged into the line sphere through the gap between the line bodies to form a line image. Since the structure is such that the bark is stripped by hitting the log that moves as it rotates, the bark is removed efficiently and with less noise. It has the same effect as the notch for peeling and scraping raw wood, and is integrated so that there is no problem when the rotary cutter enters the mold release body, making the power transmission mechanism for rotating the line ball simple. It has the effect of becoming
