Description

[Detailed description of the invention] This invention relates to drum bar force, and more specifically, to improving the drum bar force used to peel off the bark of wood as a pre-process to produce wood chips, which are raw materials for paper manufacturing. It is.

Various forms of drum bar force have been put into practical use to peel off the bark of wood.

The most orthodox type is to rotate a veranda with a notch on the inner circumferential surface, and as the veranda rotates, the wood placed inside is lifted upward along the inner surface of the veranda until it reaches an appropriate height. The wood is repeatedly dropped to the bottom of the can by its own weight, and during this lifting and falling, the notches on the inner peripheral surface of the veranda apply damage, friction, and collision to the bark, and the bark is damaged while being transferred from one end of the veranda to the other. It is designed to peel off.

Therefore, in order to sufficiently agitate the wood within the veranda in order to increase the peeling effect, and to increase the chances of friction and collision, a spiral spiral is applied to the circumferential surface from one end of the veranda, as described in Japanese Patent Publication No. 51-31740. There has been a proposal for a drum bar force that inserts and rotates a peeling tool equipped with a shaped peeling blade, but the only chance the wood would come into contact with this tool was when it was thrown into the veranda, so it was not very efficient. .

The purpose of this invention is to eliminate the above-mentioned drawbacks, and its features include a rotary shaft that extends through the edge in the radial direction and is supported, and a rotary shaft provided at the outer end of the edge of the shaft that supports the rotary shaft. It is equipped with a motor that rotates, a current-carrying member that supplies current to the motor, and a rotating notch that is attached to the inner end of the circumference of the rotating shaft and rotates with the rotation of the rotating shaft, and cooperates with a fixed notch inside the edge. To provide a drum bar force with high peeling efficiency, which is configured to peel off the bark of wood.

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

Figure 1 shows the overall structure of the drum bar force of this invention, in which a rolling wheel 5 on the edge side 4 is mounted on a roller 3 which is supported by a bearing 2 on a base 1, and A plurality (for example, three) of annular conductors 6 with an inner diameter that allows the edge to be inserted through the edge are arranged at predetermined intervals in the length direction of the edge, and the positions of the conductors are determined. A rotating shaft of a motor 13, in which a conductive brush body 11 is provided on the base 1 via an insulating material 12 in opposition to the motor 13, and an umbrella-shaped rotating notch 10 is attached to one end of the rotating shaft in a through hole 8 provided on the outer periphery of the edge side. As shown in FIGS. 2 and 3, 9 is attached so that it penetrates the edge net in the radial direction and the rotating notch is located inside the edge, and a rotating blade with a reamed blade is installed in parallel with the rotation of the edge net. The notch 10 is rotatable, and a tooth-shaped fixed notch 14 is mounted inside the edge as shown in FIG.

As shown in FIG. 1, the aforementioned motors 13 are arranged in plural numbers at predetermined intervals on the wood input side of the edge net and at constant intervals around the edge net.

In the figure, 15 is a wood input port fixed on the base 1 at one end of the edge net 4, 16 is a peeled wood outlet fixed on the base 1 at the other end of the edge net 4, and 17 is a A rim of bark or other debris protruding around the rotary notch 10 concentrically with the through hole 8;
Reference numeral 18 denotes a drive wheel that comes into contact with a drive roller (not shown).

The drum bar force of this invention has the above-mentioned structure, and the debarking operation of peeling off the bark of wood by this drum bar force will be explained below.

First, the output of the prime mover is applied to the driving wheels 18 via the rollers to rotate the edge net 4, and then when the wood a with bark is fed into the edge side 4 from the wood input port 15, the edge net 4 is turned as shown in FIG. The wood a at the bottom of the net 4 rotates along the inner wall surface on the line side as shown by the arrow as the edge net rotates, and the fixing notches 10, 14
When the wood reaches an appropriate height, it falls to the bottom of the edge net (although there is no fixed bottom) due to its own weight, rotates, collides with the fixing notches 10 and 14, and the wood pieces collide with each other. If the motor is rotated in parallel with the friction and rotation of the edge net, the rotary notch 10 will rotate relatively quickly, creating a friction and scraping action, and the bark of the wood that is continuously fed will be removed from the wood outlet. By the time the tree reaches 16, the above-mentioned collision, friction, and scraping effects work together on the bark, and the bark is completely and quickly peeled off.

As described above, this invention includes a rotary shaft that is supported by penetrating the edge net in the radial direction, a motor that is provided at the outer end of this shaft on the line side and rotates the rotary shaft, and a current that is supplied to the motor. The present invention is equipped with a current-carrying member and a rotary notch which is attached to the inner end of the rotary shaft on the line side and rotates with the rotation of the rotary shaft, and is configured to work together with the fixed notch in the edge to peel off the bark of the wood. Both the fixed and 9-rotation notches work together to quickly and completely peel off the bark of the wood.The structure is simple, so it can be easily carried out, and it has advantages such as good maintenance and operability.
