Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a continuous wood peeling machine used for peeling construction wood and before and during the production of wood chips. .

[Prior Art] - Generally, when wood is used for construction purposes or as chips, it is necessary to first remove the bark.

Various types of conventional continuous wood peeling machines have been developed, but the present inventor continuously opened the bottom of the hopper along its longitudinal direction, and installed a pipe shaft to close the bottom of the hopper. We first developed a continuous wood peeling machine (Japanese Patent Publication No. 6l-46282) equipped with a rotary peeling body with a number of peeling blades attached to its outer periphery.

This continuous wood peeling machine has a hopper that stores and peels wood, and a receiving side plate and a feeding side plate are combined to form a continuous opening along the longitudinal direction at the bottom of the hopper. It is installed inclined along the a+ direction, with one high end serving as an input portion and the other low end serving as an extraction portion.

In the f section of this hopper, a peeling rotary body is located at -L on its outer periphery.
is partially inserted so as to close the bottom opening of the hopper, and is slightly inserted along the hopper. installed.

The peeling rotary body has a plurality of step-shaped peeling blades spirally protruding from the outer circumferential surface of the pipe shaft.

This J! The debarking action of the I-connected main type wood debarking machine is achieved by driving the motor to rotate the debarking rotary body and sequentially feeding the wood into the hopper from the input section. As the peeling rotor rotates, the wood rotates and moves toward the foaming part.

At this time, the upper part of the peeling rotor is inserted and rotated so as to close the bottom opening of the hopper, so the wood is scraped up by the plurality of step-shaped peeling blades protruding from the outer periphery. The skin is rotated in the hopper in the opposite direction to the peeling rotary body, and the skin is peeled by the peeling blade, and the skin is sequentially moved to the side of the ground where the skin is continuously peeled.

The peeled bark (park) falls through the gap between the peeling rotor and the comb groove at the lower end of the side plate and is carried outside by a conveyor.

The wood accumulated on the take-out part side is peeled while continuing to rotate, and when the condition is checked from the -L part of the hopper and the peeling is completed, the shutter is lowered by the lifting mechanism to open the take-out part and the wood is removed. is dropped from the chute and sent to the unloading conveyor.

Therefore, this continuous wood peeling machine has a simple structure, is easy to manufacture and maintain, and has low equipment costs.Also, since the hopper is fixed, noise and vibration are extremely low compared to rotating drum type. Moreover, since the wood falls under its own weight, it is scraped up while being peeled off by a peeling blade protruding from the peeling rotary body, and transferred within the potsupper, which greatly improves work efficiency and reduces power costs. There are various effects such as

For this reason, most of the continuous wood peeling machines currently manufactured are of the jade structure developed by the present inventor.

However, the comb groove provided at the lower end of the side plate is formed at a depth that is not hit by the rotating bark stripping blade, so the peeling rotor, through which the peeled bark falls, and the comb south groove at the lower end of the side plate are connected to each other. There was a problem in that the gap between the hoppers was narrow and the bark, which was less than 11 g in length, would not fall through the gap and accumulate in the hopper.

Furthermore, if long bark is not discharged and accumulates in the potspar, this will inhibit the debarking action of the debarking blade on the wood and reduce the debarking efficiency, and furthermore, the long bark will be discharged outside from the dispensing part along with the completely debarked wood. Therefore, the removal work was troublesome.

In order to improve this problem, conventional bark ejection devices (unexamined Japanese patent application +
1/(62-62702) is proposed.

The hopper (wood peeling tank) l of this device is constructed by combining one side plate 2 and the other side plate 3 facing each other into a substantially U-shaped cross section so as to form a continuous opening al14 along the direction of the technician at the bottom. , a peeling rotary body 5 is provided so as to close this area. A large number of peeling blades 6 are provided on the circumferential surface of this peeling rotary body 5.
are provided protrudingly at intervals, and scrap teeth 7 are fixed between these peeling blades 6 and toward the rear of the peeling blades 6.

This scraping tooth 7 is lower in height than the barking blade 6, is thinner, and has an acute-angled protrusion on its front surface.When the scraping tooth 7 rotates, it cuts long bark and extrudes it from the gap with the side plate 2. It is designed to be discharged.

However, since a large number of the scraping teeth 7 are attached separately from the peeling blade 6, manufacturing is troublesome.1-1 Since the scraping teeth 7 are thin, the strength is weak and the durability is poor.

Moreover, since the scraping tooth 7 is separated from the skinning blade 6 and has an acute protrusion formed on the front surface, there is a drawback that when the wood is scraped, it digs into the surface and causes damage.

[Problems to be Solved by the Invention] In view of these conventional problems, the present invention has been developed as a result of various studies and has been developed to solve the problems of 4-1 wood, which is easy to manufacture, has high strength, and has excellent durability. The bark that has been peeled off for a long time is cut into short pieces and allowed to fall through the gaps, improving the efficiency of peeling the wood.
I made it E'! We provide a JA continuous wood peeling machine.

[Means for solving the problem] The present invention 1 forms a continuous open O part along the longitudinal direction at the bottom of a hopper for storing and peeling wood between a pair of opposing side plates, and In a continuous wood peeling machine, a peeling rotor having a number of peeling blades protruding from the outer circumferential surface of a pipe shaft is provided so that its hi closes the bottom opening of the hopper, and the peeling blade is placed on the forward side in the rotation direction of the peeling blade. It is characterized in that a skin cutting blade is formed integrally with this.

[Function] In the continuous wood peeling machine of the present invention, the wood put into the hopper is scraped up while being peeled by the peeling blade of the peeling rotor, and falls under its own weight, and continues to revolve while rotating inside the hopper and is transferred. The skin is peeled off by the skin peeling blade and sequentially moves to the extraction section side.

The bark stripped off by the barking blade falls through the gap between the barking rotor and the toothed grooves on the side plate, slides along the bark guide, is collected on a conveyor, and is carried out of the device.

At this time! If the separated bark is long, it is cut into short pieces by the bark cutting blade that is integrally formed at the rear of the bark blade, and is quickly discharged from the gap. In addition, since the skin cutting blade is formed into a block integrally with the skin stripping blade, it is easy to attach to the pipe shaft and has high strength.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Figure ff11 to Figure jS4 show one embodiment of the present invention, and this hopper (wood peeling tank) l has one side plate 2 and the other side plate 3 facing each other as shown in Figure 1. They are combined into a U-shaped cross-section so as to form a continuous opening 4 along the yam direction at the bottom.

A side plate 2 forming a side wall of the hopper 1 has at least a curved portion curved inwardly and stands upright in the vertical direction, and a side plate 3 has at least a lower portion inclined inward and stands upright in the vertical direction. Further, as shown in FIG. 2, the hopper 1 is attached to the support frame 8 with a slight inclination at an angle α along its longitudinal direction.
Place the higher end side into the input section 9. The other end, which is lower, is a take-out part 7 in which a shutter 1O is provided so as to be able to move up and down.

A peeling rotating body 5 is provided at the bottom of the hopper 1, and the upper part of its outer periphery is partially inserted so as to close the bottom opening 4, and is attached along the hopper 1 at a slight inclination.

As shown in FIG.
2, a large number of blocks 14, in which a peeling blade 6 and a peeling blade 13 are integrally formed, protrude in a spiral shape in the axial direction, for example, four blocks 14 are provided at equal intervals of 30 degrees in the circumferential direction.

As shown in FIG. 3, this block 14 is integrally formed with a rising, depressed peeling blade 6 on the front side in the direction of rotation shown by the arrow, and a skin cutting blade 13 with a U-shaped groove sunken on the rear side. ing. Further, the marginal portions of the skinning blade 6 and the skinning blade 13 are formed at approximately the same height, and are fixed to the surface of the pipe shaft 12 by welding.

Further, as shown in FIG. 2, a round bar-shaped shaft 15 is attached to the inner end of the peeling rotary body 5, and this shaft 15 is supported by a bearing 16. A motor 17 is connected to the end on the 19 side.

Also, one side plate 2 constituting the hopper l and the other side &
At the edge of the opening fi4 of No. 3, a protrusion was provided on the peeling rotary body 5, as shown in FIG. A comb tM groove 18 is formed corresponding to the pitch so that the block 14 in which the peeling blade 6 and the peeling blade 13 are integrated does not hit.

Further, a shutter 10 is provided in the take-out section 11 and is supported by a lift 41 structure 19 so as to be tilted in the direction in which the wood 20 is taken out and can be raised and lowered.

In the figure, 21 is a conveyor for carrying out the peeled wood 20, 22 is a conveyor for carrying out the peeled bark 24,
23 is a bark guide, and 25 is a shooter.

Next, the operation of the continuous wood peeling machine having the following structure will be explained.

The motor 17 is driven to rotate the peeling rotary body 5 toward the side plate 2 in the direction of the arrow.

In this state, when the wood 20 is sequentially fed into the hopper 1 from the official section 9, the wood 20 is rotated toward the take-out section 11 by the rotation of the peeling rotary body 5 inside the hopper L, which is installed at an angle. Move and go.

In this case, as shown in FIG. 1, the peeling rotary body 5 whose upper portion is inserted so as to close the bottom opening 4 of the hopper l is rotating in the direction of the arrow, so that the wood 20 is placed on the surface of the peeling rotary body 5. The skin is scraped up while being peeled off by a protruding step-like peeling blade 6. At this time, since the heights of the tops of the peeling blades 13 formed behind the peeling blades 6 are approximately the same, they do not dig into the surface of the wood 20 and cause damage.

The scraped wood 20 is stopped by the side plate 2 and reversed, rotates inside the hopper 1 in the opposite direction to the peeling rotary body 5, is sent by the side plate 3, falls with its own hair, and returns to the hopper. 1
It continues to revolve while rotating within itself.

In this way, the wood 20 is peeled by the peeling blade 6 while rolling in the hopper 1 inclined in the longitudinal direction, and taken out one by one 71!
The blade 6, which moves toward the side, is spirally protruded from the outer periphery of the pipe shaft 12, so it smoothly moves from the input section 9 of the hopper 1 to the output section 11 side by the action of the feed screw. be transported.

The bark 24 stripped off by the bark stripping blade 6 falls through the gap between the bark stripping rotor 5 and the comb tooth groove 18 of the side plate 2.3 and slides on the bark guide 23, as shown in FIG. It is collected on the lower conveyor 22 and carried out of the device.

Konoto! ! 21 If the separated bark 24 is long, the comb 1t1
1118 and cannot fall through the gap, but as shown in FIG. 4, the long bark 24 enters the U-shaped bark cutting blade 13 formed integrally at the rear of the peeling blade 6, cuts it short, and quickly discharges it from the gap. Ru. Further, the long bark 24 that remains in the U-shaped groove of the peeling blade 13 falls from the U-shaped groove when the peeling rotary body 5 rotates and comes out of the hopper 1 and reaches the lower part. - While rolling in the hopper 1 in this manner, the peeled wood 20 is transferred to the take-out part 11 side, and the wood 20 accumulated in the take-out part 11 is further stripped while continuing to rotate.

At this time, the shutter 10 is in a closed state as shown in FIG. 2, and the wood 20 that has moved toward the take-out portion 11 continues to rotate while being pressed against the shutter IO. Since the peeling rotary body 5 is rotating, the block 1 protruding from it
A piece of wood 20 is often sandwiched between the shutter lO and the shutter lO.

At this time, since the shutter 10 is inclined in the direction in which the wood 20 is taken out and is movable up and down, the end of the wood 20 that is in contact with the shutter 10 slides on the inclined surface and is lifted upward and escapes. .

As a result, no large force is applied to the peeling rotor 5 or the shutter lO, making it possible to prevent damage to the device and overload of the motor 17.

Once the wood 20 accumulated in the take-out section 11 has been stripped, its condition is checked from the top of the hopper 1, and the lifting mechanism 19 is activated to lower the shutter 10 little by little. Overcoming 10 and 1
! I! The height of the shutter 10 is adjusted so that the water is continuously supplied to the shooter 25.

When the shutter lO is slightly lowered in this way, the flow of the wood 20 is slightly obstructed and the wood 20 is peeled in a jam in the take-out section 11, and the wood 20 is lifted up while sliding on the slope of the shutter lO, and the wood 20 that has been completely peeled is smoothly removed. shutter 1
0 and is supplied to the shooter 25. The wood 20 supplied to the chute 25 slides down there and is carried out to the outside by the carry-out conveyor 21.

In this way, the lumber 20 is sequentially introduced from the input FIA 9 to i! I! The skin is peeled off continuously.

:jS5 shows another embodiment of the present invention, in which the block 14 has a rising step-like peeling blade 6 on the front side in the rotational direction and a peeling blade 13.13 with a U-shaped groove on the rear side. is formed. Further, the top portion of the peeling J blade 13.13 is formed to be successively lower than the height of the top portion of the peeling blade 6.

FIG. 6 shows another embodiment of the present invention, in which the block 14 has a step-like peeling blade 6 rising up on the front side in the rotational direction, and a step-like peeling blade 13 . . . integrated on the rear side. is formed.

In this system, the bark stripping rotary body 5 is rotated in the forward direction to strip the wood 20 with the bark stripping blade 6, and when long bark 24 accumulates, it is temporarily rotated in the reverse direction and the bark is cut with the bark cutting blade 13. It is.

FIG. 7 shows a different embodiment of the present invention, in which two peeling rotors 5.5 are stored and placed between one side plate 2 of the hopper 1 to promote the rotation of the wood 20. An auxiliary rotor 26 is attached. This auxiliary rotor 26
A plurality of peeling blades 6 are provided protruding from the surface.

In addition, there is a blocking tree 2 between the two peeling rotary bodies 5.5 installed in parallel.
7 is provided, and this blocking tree 27 has comb grooves 18.7 on both sides.
18 is formed, and the lower part of the blocking tree 27 is supported by supports 28 whose intervals become wider toward the bottom.

In this structure, the rotation of the wood 20 and the peeling action are promoted by the auxiliary rotor 26 on which the peeling blades 6 are protruded, and the spacing between the supports 28 that support the blocking wood 27 becomes wider toward the bottom. Therefore, the supporting strength is improved, and the fallen bark 24 is slippery and can be easily discharged.

Furthermore, the heights of the peeling rotors 5.5 arranged in parallel are not limited to being at different levels, but may be the same height, and the rotation direction is not limited to one direction, but may be opposite, and a plurality of peeling rotors 5 are arranged in a straight line. In this case, the direction of rotation may be changed between the feeding section side and the rock section side.

In the embodiment E, a structure in which one peeling rotor 5 is continuous in the axial direction is shown, but a structure in which a plurality of peeling rotors 5 are connected in a straight line via bearings 16 is also possible. In this case, the motor 17 is connected to both sides. It is best to install it on

Furthermore, in the above embodiment, a case was shown in which 4 parts of the hopper 1 were opened over the entire length, but the input section 9 and the take-out section 1 were opened.
A lid may be attached to the middle part except for 1. In this case, the lid may be flat or round, and A may be detachable from hopper 1 or may be formed into a body. Furthermore, hopper = 1
The cross-section is not limited to a U-shaped cross section over the entire length, but only the input side is formed with a U-shaped cross-section, and the output side is cylindrical or 1:
