Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bar force for removing the bark of wood, and in particular, the present invention relates to a bar force that removes the bark of wood, and in particular, uses a simple mechanism to efficiently remove the bark of wood regardless of its diameter, length, joints, etc. It is designed so that it can be removed.

Various types of bar force have been used in the past.

However, these devices have complicated feeding and rotation mechanisms for the wood or cutlery, and are inevitably expensive.

In addition, it is generally difficult to adapt to the length and diameter of wood, and furthermore, it is difficult to process wood that has convexities such as bends and knots.

The present invention attempts to solve the above-mentioned problems all at once by fundamentally changing the structure of the conventional bar force.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments.

Reference numerals 1 and 1' denote a pair of frames arranged so that the mutual spacing can be adjusted.

Each frame 1, 11 has a pair of lower wheels 2,
2, 2/, 2/, and upper wheels 3, 3, and 3' are rotatably arranged.These lower and upper wheels are made of elastic material such as rubber or synthetic resin. Configure.

Each pair of lower wheels 2, 2 and z, 2' are arranged at a slight angle in the horizontal force direction with respect to the center line of the wood 30 to be treated.

In the embodiment shown in FIG. 1, each lower ring 2, 2° 2', 2' is deviated by deviating the entire frame 1, 1' with respect to the center line of the timber 30. , each frame 1, 1' is arranged at right angles to the center line of the timber 30, on which each lower wheel 2, 2.2', 2' (and its axis 4.4, 4', 4') ) may be declination only.

Further, each pair of lower wheels 2, 2 and z, 2' are rotated in the same direction and reversibly by motors 5, 5', respectively.

In the illustrated embodiment, the lower part 1182.2 and 2/, 2/ of each pair is connected to the motor 5, 5 via a chain 6.6' and a sprocket 7-11, 7'-11', respectively.
' However, in place of these chains and sprockets, gears, belts, and other transmission means may be used.

On the other hand, the upper shafts 3, 3 and 3', 3' of the @reporter pair are horizontal, opposite to the upper shafts 2, 2, 2', 2' with respect to the center line of the wood 30, respectively, as shown in FIG. Although it is desirable to make the lumber 30 slightly deviated in the direction in order to ensure more reliable feeding of the lumber 30, it may also be arranged perpendicular to the center line of the lumber 30, as shown in FIG.

Each pair of upper shafts 3, 3 and 3' corresponds to each pair of lower shafts 2, 2 and 2' as shown in -C1 in FIG.

Although it may be arranged outside of 2', it may also be arranged almost directly above or inside the lower shaft.

Note that the upper shafts 3, 3 and 3', 3' may be simply rotatable, but they must be driven to rotate in the same direction as the lower shafts 2, 2, 2/, 2/ by a motor (not shown). In this case, the wood 30 can be fed more reliably.

Further, each pair of upper shafts 3, 3 and 3/, 3/ are respectively movable up and down.

That is, as shown in FIG. 2 as an example, each frame 1,
One end of arm 12°12' is pivotally connected to arm 1'.
2 and 12' are vertically rotated by cylinders 13 and 13', and upper shafts 3.3' and 3' are attached to the other ends of the arms 12 and 12'.

Moreover, each pair of upper axes 3, 3, 3', 3' are as follows:
In order to make it evenly contact the surface of the wood 30,
As shown in FIGS. 2 and 4, the swinging member 14
(14'...not shown) the arm 12,
12', and each pair of upper shafts 3, 3
, 3', and 3' are swingable in the front-rear force direction (left-right force direction in FIG. 2).

Note that 15 is the axis of the upper shaft 3, and 16 is a pivot.

Further, on the outside of the valley frames 1, 1', there are blades 17, 17 for contacting the surface of the wood 30 and removing the bark thereof.
' are arranged so that they can be raised and lowered.

That is, as an example, as shown in FIG. 2, one end of the arms 18, 18' is pivotally attached to each frame 1°1', and the arms 18, 18' are rotated in the vertical direction by cylinders 19, 19'. In this way, the blades 17, 17' are attached to the other ends of the arms 18, 18'.

In addition, the cutter 17 can be used to prevent bending of the wood 30 and unevenness of the surface.
, 17', the cutter 17°1γ is always pressed against the surface of the wood 30 by a spring.

For this purpose, the arms 18, 18' themselves may be constructed of spring plates or other elastic members, but as shown in FIGS. , 1' may be provided with springs 20, 20'.

Various blades can be used as the blades 17 and 17', but as shown in Figs. It is desirable that the cutter be rotatably mounted on the other ends of the arms 18 and 18' so that the peripheral edge of the cutter is brought into contact with the lower surface of the wood 30.

When using the bar force of the present invention configured as described above,
First, depending on the length of the wood 30 to be processed, move the frame 1 or 1' of -1 to adjust the distance between the two frames, and then move the wood 30 to the lower axis 2 of each frame 1°1'. 2 and between 2' and 2'.

Subsequently, each pair of upper shafts 3, 3 and 3'. 3' is lowered to abut against the upper surface of the wood 30, and the blades 17, 1
7' is raised and brought into contact with the lower surface of the wood 30.

In this state, connect the lower shafts 2, 2.2', 2' to the motor 5°5'.
This causes them to rotate in the same direction.

For example, in FIG. 2, the lower axes 2, 2, 2',
2' clockwise, the wood 30 rotates counterclockwise, so the upper shafts 3, 3 that come into contact with the wood 30 rotate.
The blades 17 and 17', which contact the wood 30 in a diagonally downwardly inclined state at degrees 3' and 3', rotate clockwise, respectively.

At this time, the lower shafts 2, 2.2', 2' (and the upper shafts 3,
3, 3', 3') are horizontally deviated from the center line of the timber 30, so the timber 30 is sent to the right in FIG.

In addition, lower shafts 2 , 2 , 2' , 2' as necessary
When rotated in the opposite direction to the above, the wood 30, the upper shafts 3, 3.3', 3' and the blades 17, 17' rotate in the opposite direction, and the wood 30 becomes as shown in FIG. Move to the left.

Therefore, the wood 30 has the lower axis 2 , 2 , 2' , 2'
The bark is rotated and moved in a desired direction while being held between the upper shaft 3, 3.3', 3' and the upper shaft 3, 3.3', 3'.
17'.

After removing the bark of the wood 30 in this way, the upper shafts 3, 3, 3', 3' are raised and the cutter 17.1γ
is lowered and the wood 30 is removed.

The next piece of wood is then treated in the same manner as above.

As explained above, in the present invention, the lower shaft and upper shaft attached to each frame perform all the functions of holding, rotating and feeding the wood, which simplifies the overall structure of the device and reduces the number of parts. It's done.

In addition, since the wood was fed by rotating the lower shaft (and upper shaft) at a horizontal angle with respect to the center line of the wood, the motor that rotationally drives the lower shaft (and upper shaft) may be small.

Therefore, the bar force of the present invention is significantly lighter and cheaper than conventional ones.

Furthermore, the lower shaft and the upper shaft are each attached to a pair of frames, and the distance between the two frames can be adjusted according to the length of the wood, and the upper shaft and the cutter can be moved up and down. Bar forces can advantageously handle wood of any length or diameter.

Furthermore, since the lower and upper shafts are each made of elastic material, they absorb any convexities such as knots or slight bends in the wood, allowing the wood to rotate and feed smoothly. becomes possible.

Furthermore, since the blade is always pressed against the surface of the wood by the spring, the blade can sufficiently follow the curves and surface irregularities of the rotating wood.

Therefore, according to the present invention, even curved or uneven wood can be processed smoothly.

As described above, a disk-shaped cutter was arranged so as to be rotatable in a diagonally downward direction with respect to the center line of the wood, so that the peripheral edge of the cutter was in contact with the lower surface of the wood. In this case, the cutter is rotated smoothly by the rotating wood, so that even if there are protrusions such as knots on the surface of the wood, they can be easily removed.

Furthermore, since the corners of the peripheral edge of the disk come into contact with the wood, the bark removal efficiency is also improved.
