Description

[Detailed description of the invention] This invention relates to a drum barker, and more specifically, a rotary peeling tool (rotary force vine) with a cutting blade formed on the circumference is inserted between rotating cans for rotating and transporting wood. This invention relates to a drum barker that forcibly removes the bark from wood.

In this invention, a plurality of rotating can bodies are arranged in series with a slight gap between them, and two cylindrical rotary force vines are provided below the gap to peel the raw wood being transferred inside the can bodies. ,
In a drum bar cover in which these cutters are mounted on a common rotating shaft so as to face each other on one side, and these opposing cutters can be rotated in the same direction or in different directions, the common rotating shaft of the two cylindrical rotary force vines is The object of the present invention is to provide a drum coverr characterized in that the drum coverr is supported at its center and both ends by bearings fixed to mounting members, respectively.

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

Figure 1 shows the overall configuration of the drum cover of this invention.
A to 1C are a plurality of rotating can bodies, each of which is mounted on a roller 4 supported by a bearing 3 on a base 2 via a rolling wheel 5 attached to the outer periphery of the rotating can body. Then, the wood put into the rotary can body 1C from the wood input hopper 6 installed at one end is applied by a drive mechanism (not shown),
By rotating in the direction of the arrow, the wood can be moved inside the rotary can bodies 1b, la and taken out from the wood outlet 7 installed at the other end.

Reference numeral 8 denotes a rotary force vine device, one end of which is pivotally supported by a shaft 91 at the end of a vertical member 90 forming the mounting machine frame 9, and a spring between the other end and a frame member 92 fixed to the vertical member 90. A rotating shaft 80 and its bearings 81 to 83 are attached to a mounting member 94 which is elastically attached via an elastic member 93 such as
With two cylindrical rotary force vines 84. 85 are mounted so that their end faces face each other, the rotary force vine 84 between the bearings 81 and 82 is fixed to the shaft 80, and the bearings 82,
A rotary force vine 85 between the shaft 83 and the rotary force vine 83 is rotatably attached to the shaft 80, and pulleys 86 and 87 are attached to the end of the shaft 80 and the end of the rotary force vine 85, respectively. It is constructed so that it can be rotated independently by motors 88 and 89 attached to the (2) belt or other power transmission means.

The rotary force ivy 84.85 has a diameter approximately equal to the diameter of the rotary can body, as shown in FIG. A cylindrical body 841 whose length is slightly longer than the diameter of the light.
, 851 made of steel, and one or more approximately V-shaped blades (single-edged or double-edged) 842 , 852 are attached to the surface thereof in a spiral shape.
Hollow shaft 84 provided with a keyway through end plates 843 and 845
6, a pulley mounting shaft 856 is attached to the body 851 via bearings 853, 854 and an end plate 855.

The rotary force vine device 8 is shown in FIGS. 1, 2 and 4.
As shown in the figure, most of the total length of the rotary force vine device 8 is connected to the rotary can due to the interval 10 which is wider than the diameter of the end of the rotary force vines 84, 85 provided between the rotating cans 1a to 1C. A fixed circular body 13 is installed in the gap 12 remaining on both sides of the rotary force vines 84 and 85, and the rotary force is inserted into the fixed circular body 13 at an inclination angle of approximately 40° with the mounting frame 9 interposed therebetween. A gap cover 14 that also serves as a force bar is attached.

In addition, 95 in the figure is a mounting member 94 with a roller 96 attached to the end.
The horizontal vibration prevention member is attached to the frame member 92.

Note that the part indicated by number G in FIG. 2 is a fixed guide member.

The drum barker of this invention is constructed as described above, and the case where the bark of wood is peeled off with this drum barker will be explained below.

When the wood W is continuously fed into the rotary can body 1C from the wood input hopper 6 shown in FIG.
At 5, an agitating motion is applied such that the material is lifted along the inner wall of the rotating can and then falls, gradually moving toward the discharge port 7.

During this movement, the blades 842 and 852 of the rotary power vines 84 and 85 are inserted into the inner part of the rotary can through the gap 10 and rotated individually via power transmission means by motors 88 and 89, as shown in FIG. It bites into the side of the wood that is moving while rolling in a direction perpendicular to the wood W, scraping the bark, and the two work together due to the collision of the fixed notch 15 to strip wood with hard bark, such as small-diameter wood, frozen wood, or walnut wood. It can be done efficiently.

The rotary power vines 84,85 are operated by rotating the motor 88 in the forward direction and rotating the motor 89 in the reverse direction in the case of small diameter trees, frozen trees, or hard trees. Effective debarking can be achieved by rotating the motors 85 forward and backward, and in the case of large-diameter trees or wood whose bark easily peels, by rotating both the motors 88 and 89 in the forward direction.

A large amount of wood was clogged on the input port side, causing rotary force ivy 84.8
When an excessive load is applied to the shaft 5, the elastic member 93 is deflected and the mounting member 94 is moved back around the shaft 91, thereby avoiding the excessive load.

As described above, this invention arranges a plurality of rotating cans in series with a slight gap between them, and below the gap are two cylindrical cans into which the raw wood to be peeled is to be peeled. In a drum barker that is provided with rotary power vines, these vines are mounted on a common rotating shaft so as to face each other on one side, and these opposing vines can be rotated in the same direction or in different directions, two cylindrical rotary The common rotation axis of power ivy,
The center and both ends are supported by bearings fixed to mounting members, and the two cylindrical rotary power vines are rotated in the same or different directions to debark raw wood, making it efficient. When peeling is performed, an abnormal load is applied to the common rotating shaft through each cutter, but in this invention, the rotating shaft is supported at the center and both ends by bearings fixed to the mounting member, so that the common rotating shaft is This has the effect of sharing the abnormal load on the shaft, preventing it from breaking, and maintaining smooth operation of the drum coverr for a long time.
