Description

[Detailed Description of the Invention] [Field of Application in Industry-1-] The present invention relates to an improvement of a continuous wood peeling machine used for peeling for construction purposes and for peeling in the pre-process of manufacturing wood chips. be.

[Prior Art] Generally, when wood is used for construction purposes or as chips, it is first necessary to remove the bark. As a conventional continuous wood peeling machine,
For example: ■ A peeler that has many peeling blades protruding from the inner peripheral wall of a rotating drum and peels the wood put into the drum while rotating the drum ■ A large number of circumferential slits in the shape of a comb at the bottom. A peeling rotary body with a number of blade-shaped peeling blades protruding from the shirt i corresponding to the slit spacing is placed on the fixed drum, and the wood thrown into the fixed drum is
There is a peeling machine that peels the skin with a peeling blade that rotates inside the drum through a slit at the bottom of the drum as the peeling rotor rotates.

However, the rotary drum-type peeling machine described in (1) rotates the drum and the wood loaded inside at the same time, which causes large noise and vibrations, leading to pollution problems.2.There was a problem of high equipment and power costs. .

In addition, the peeling machine (■) has a complicated structure of the peeling rotor to which many blade-shaped peeling blades are attached, and the equipment cost is high.Moreover, it is necessary to drill many slits in the bottom of the drum to accommodate the peeling blades. However, there were disadvantages such as the slit processing was troublesome and thick plates had to be used for strength, and it was time-consuming to check the lubrication of the equipment.

In order to solve these problems, the inventor of the present invention created a peeling rotary body in which the bottom of the hopper is continuously opened along its longitudinal direction, and a number of peeling blades are attached to the outer periphery of the pipe shaft so as to close the openings. A continuous wood peeling machine was developed first (Special Publication Sho-61-46282).

This continuous wood debarking machine has a hopper for storing and debarking 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 obliquely along the longitudinal direction, with one high end serving as an input portion and the other low end serving as an extraction portion.

A peeling rotary body is partially inserted into Wfi8 of this hopper so that the upper part of its outer periphery closes the bottom opening of the hopper, and is attached at a slight inclination along the hopper.

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

The continuous wood peeling machine operates by driving a motor to rotate the peeling rotary body and sequentially feeding the wood into the hopper from the input section. As the rotating body rotates, the wood rotates and moves toward the extraction section.

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 block-shaped peeling blades protruding from the circumferential surface. The skin is rotated in the hopper in the opposite direction to the peeling rotary body, and then 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.

Therefore, this continuous wood peeling machine has a simple structure, is easy to manufacture, maintain and inspect, has low equipment costs, and has a fixed hopper, so noise and vibration are extremely low compared to rotating drum type machines. In addition, the wood falls due to its own weight, is scraped up while being peeled by a peeling blade protruding from the peeling rotary body, and is rolled inside the hopper, which greatly improves work efficiency and reduces power costs. There are effects such as

For this reason, most of the continuous wood peeling machines currently manufactured have the above structure, but since they only have one peeling rotor, in order to further improve efficiency and increase the number of processing rods, the peeling rotor A system in which two wires are installed side by side has also been developed.

In this structure, since a peeling blade is provided protruding from the outer periphery of the peeling rotary body, adjacent peeling rotary bodies must be arranged at intervals. For this reason, it is necessary to install a closing plate between adjacent peeling rotors, and the closing plate has comb-tooth grooves formed on both sides along the longitudinal direction through which the peeling blade passes.

As a result, bark (park) falls from the gap between the peeling rotor and the closing plate, gets caught on the support that supports the closing plate, and accumulates, making it difficult to discharge the bark smoothly and reducing the rotational force of the bark peeling rotor. Resulting in. Further, since the closing plate is installed on the support frame along the peeling rotary body, there is a drawback that vertical vibration and lateral vibration occur.

[Problems to be Solved by the Invention] In view of these conventional problems, the present invention has been developed as a result of various researches, and has been developed to provide a simple structure for smoothly removing bark that has fallen from the gap between the peeling rotor and the closing plate. This prevents the rotational force of the peeling rotor from decreasing, and quickly discharges the peeling material on a conveyor.
To provide a continuous wood peeling machine that prevents vertical vibration and lateral vibration of a closing plate.

[Means for Solving the Problems] The present invention provides a method for storing wood between a pair of opposing side plates. A continuous opening is formed along the longitudinal direction at the bottom of the hopper, and a plurality of peeling rotors each having a large number of peeling blades protruding from the outer peripheral surface of the pipe shaft are arranged in parallel. In a continuous wood peeling machine, the upper part of the hopper is arranged to close the bottom opening of the hopper, and a closing plate is provided between adjacent peeling rotors, and the closing plate has combs on both sides along the longitudinal direction. This is characterized in that a tooth groove is formed and the lower part of the closing plate is supported by a support whose spacing becomes wider in the F direction.

1. The continuous wood peeling machine of the present invention scrapes the wood fed into the hopper while being peeled by the peeling blade of the peeling rotor.
The hair falls off due to its own hair, continues to revolve inside the hopper, and is then peeled off by a peeling blade and sequentially moved to the extraction section.

At this time, the bark that falls from the gap between the peeling rotor and the comb tooth grooves slides down the slope of the support, which is formed so that the gap becomes wider downward, and does not accumulate here. are smoothly collected on a conveyor. Therefore, it is possible to prevent the rotational force of the peeling rotor from becoming low due to bark clogging.

Further, since the supports are formed so that the spacing becomes wider toward the bottom and have greater strength, the support strength of the closing plate is improved, and it is possible to reliably prevent vibrations and lateral vibrations.

[Example] The present invention will be described in detail below with reference to the drawings.

FIGS. 1 to 3 show an embodiment of the present invention, and this hopper (wood peeling tank) 1 has one side plate 2 and the other side plate 3 facing each other as shown in FIG. They are combined to form a continuous opening 4 along the long hair direction at the bottom thereof.

A side plate 2 forming a side wall of the hopper 1 has at least an upper portion curved inwardly and is erected in the downward direction, and a side plate 3 has at least a lower portion inclined inwardly and erected in the 1-dor direction.

In addition, the hopper 1 is mounted on the support frame 9 with a slight incline along the longitudinal direction, and as shown in FIG. ]
There is only a take-out part 7 provided at the bottom.

At the bottom of this hopper 1, two wooden barking rotors 8.8 are arranged side by side, and a part of their outer periphery is partially inserted so as to close the bottom opening 4, and is slightly inclined along the hopper 1. installed.

As shown in FIGS. 1 and 2, the stripping rotary body 8 has stripping blades 11 in the shape of stepped blocks arranged on the outer peripheral surface of the pipe shaft 10 at equal intervals of, for example, 30 degrees in the circumferential direction and at axial angles. A large number of spiral protrusions are provided in the direction.

Also, a round bar-shaped shaft 12 is provided at both ends of the peeling rotary body 8.
The shaft 12 is supported by a bearing 3, and a motor 14 is connected to the end thereof on the input section 5 side.

In addition, at the edges of the open portions 4 of one side plate 2 and the other side plate 3 constituting the hopper 1, as shown in FIGS. The comb tooth groove 1 corresponds to the pitch so that the peeling blade 11 does not hit.
5 is formed.

Furthermore, a closing plate 17 for preventing the falling of the wood 16 is provided between two peeling rotary bodies 8.8 arranged in parallel on different levels, and block-shaped peeling blades 11 that rotate on both side edges of this closing plate 17 are provided.
A comb tooth groove 15 is formed corresponding to the pitch so that the comb teeth do not hit each other. The comb tooth grooves 15 are formed at, for example, loo+sm intervals corresponding to the arrangement pitch of the skinning blades 11.

As shown in FIG. 2, the closing plate 17 is provided at an angle between the peeling rotary bodies 8.8 arranged in parallel at different levels, and its lower part is supported by a support body 18. This support body 18 is constructed by aligning the L portions of the two plate-shaped side plates 18a, 18a, and aligning the L portions of the bottom plate 18b such that the gap becomes wider toward the F portion.
It is joined to form a triangular shape.

Furthermore, a triangular rib 19 is provided between the −L portion of the support 18 and the bottom surface of the convex portion 15a of the comb tooth groove 15 of the closing plate 17.
They are joined at a pitch interval of the comb tooth grooves 15.

In the figure, reference numeral 21 indicates a conveyor 122 disposed in front of the shutter 6 for carrying out the peeled wood 16, 23 a conveyor for carrying out the peeled bark 20, and 24 a conveyor for carrying out the peeled wood 16.
is a bark kite.

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

The motor 14 is driven to rotate the peeling rotary body 8.8 in the same direction toward the side plate 2.

In this state, when the wood 16 is sequentially fed into the hopper 1 from the input part 5, the wood 16 is rotated toward the take-out part 7 by the rotation of the peeling rotors 8, 8 inside the hopper 1, which is installed at an angle. while moving.

At this time, as shown in FIG.
The upper parts of the two peeling rotors 8.8 arranged side by side are inserted so as to block the hopper 1, and they rotate in the same direction. The skin is scraped up while being peeled off by the blade 11. Scraping L
The garata wood 16 is stopped by the side plate 2 and turned over.
It rotates inside the hopper 1 in the opposite direction to the peeling rotary body 8.8, is fed by the side plate 3, falls under its own weight, and continues to revolve while rotating inside the hopper 1.

In this way, the wood 16 rolls in the longitudinally inclined hopper 1 and is peeled by the skinning blade 11, and is sequentially removed from the ground section 7.
It moves unevenly. Moreover, since the peeling blade 11 is provided in a spiral manner protruding from the outer periphery of the pipe shaft IO, it is smoothly transferred from the input section 5 of the hopper 1 to the take-out section 7 side by the action of the feed screw.

The bark 20 peeled off by the peeling blade 11 falls from the gap between the peeling rotary body 8.8 and the side plate 2.3 and between the peeling rotary body 8, 8 and the closing plate 17, as shown in the first rj4. , the bark slides on the bark guide 24, is collected on the conveyor 23, and is carried out of the apparatus.

At this time, the peeling rotor 8.8 and the comb tooth groove 15 of the closing plate 17
The bark 20 that fell through the gap between the supports 18 is formed in a triangular shape with the spacing becoming wider as it goes downward.
The particles slide down the slope of the flat plate 18a and are smoothly collected on the conveyor 23 without being collected there. Therefore, it is possible to prevent a decrease in the rotational force of the peeling rotary body 8 due to clogging of the bark 20.

Further, this support body 18 is formed in a triangular shape, and triangular ribs 19 are connected between the upper part of the support body 18 and the bottom surface of the convex portion 15a of the comb tooth groove 15 of the closing plate 17 at the pitch of the comb tooth groove 15. This improves the strength and prevents the bark 20 from being bent even if it gets caught on the convex part 15a.Furthermore, the support strength of the long closing plate 17, which is more than 6 m long, is improved and vertical vibrations are prevented. It is possible to reliably prevent horizontal vibration.

While being transferred in the hopper 1 in this way, the peeled wood 16 is sequentially transferred to the take-out part 7, and the wood 16 that has accumulated in the take-out part 7 is further peeled while continuing to rotate, and this state is transferred to the hopper 1. When the peeling is completed by checking from the upper part of the wood, the shutter 6 is lowered by a drive mechanism (not shown), the take-out part 7 is opened, and the wood 16 is dropped from the chute 21 and sent to the conveyor 22 for carrying out.

In this way, by sequentially feeding the wood 16 from the feeding section 5, peeling is performed continuously.

FIG. 4 shows another embodiment of the present invention, in which the closing plate 17
The support body 18 that supports the is composed of two curved side plates 18c,
The upper parts of 18c are joined to the bottom plate 18b, and the lower parts are joined to the bottom plate 18b so that the distance becomes wider downward.

This is effective when the spacing between the skinning rotors 8.8 is narrow because the side plate 18c is curved along the trajectory of the skinning blade 11.

5 and 6 show another embodiment in which the left and right peeling rotors 8, 8 have the same height, and FIG. 5 shows a part of the side plates 18a, 18a combined in a square shape. This is a support body 18 to which a flat plate 18d perpendicular to is joined. Also, FIG. 6 shows the side plate 18a.

18a is joined to 1- of the bottom plate 18b in a trapezoidal shape.

In addition, in the above embodiment, for the one provided with the rib 19, if
However, it is also possible to use one without the ribs 19.

Furthermore, when the distance between adjacent peeling rotors 8.8 is narrow, the arrangement pitch of the comb tooth grooves 15 formed on both side edges of the closing handle 17 may be shifted.

In addition, in the embodiment described in -1-, a structure in which one stripping rotary body 8 is continuous in the axial direction is shown, but a structure in which a plurality of peeling rotary bodies 8 are connected in a straight line through bearings 13 may also be used. It is better to install the motor 14 on both sides.

In addition, in the embodiment described above, two peeling rotors 8 are arranged side by side, but three or more may be used, and the convenient position of the peeling rotors 8. It is not limited to those that are shifted, but those that are the same height may also be used.

Furthermore, the rotation directions of the peeling rotors 8.8 arranged in parallel are not limited to the same direction, but may be opposite directions, and when a plurality of peeling rotors 8 are arranged in a straight line, the rotation direction is different between the input section side and the take-out section side. may be changed.

In the above embodiment, the second part of the hopper 1 is opened over its entire length, but it may be opened in the middle part excluding the input part 5 and the take-out part 7. In this case, the lid may be in the shape of a top plate or round, and the lid may be removable or integrally formed with the hopper 1. Further, the hopper 1 is not limited to having a U-shaped cross-section over its entire length, but may have a U-shaped cross-section only on the input side, and may have a cylindrical shape or a cylindrical shape with an open top on the take-out side.

The present invention can also be applied to a continuous wood peeling machine in which an auxiliary rotor is attached between one side plate 2 or the other side plate 3, which is the side wall of the hopper 1, to promote rotation of the wood 16.

The shape of the skinning blade jl is not limited to one in which the rising part on one side is stepped. If the peeling rotary body 8 is rotated 7E in the reverse direction depending on the operating condition, the peeling blade 11 may have a stepped shape on both sides.
The most suitable shape can be selected depending on the operating conditions, the material of the wood, etc.

Further, the peeling blade 11 is not limited to being directly fixed to the outer circumferential surface of the pipe shaft 10 by welding, but may be detachably joined with bolts.

[Effects of the Invention] As described in 1-1 above, the continuous wood peeling machine according to the present invention has a simple structure, and the bark that has fallen from the gap between the peeling rotor and the closing plate can be smoothly removed and quickly transported by a conveyor. This prevents the rotational force of the peeling rotor from becoming low, and also prevents the vibration and lateral vibration of the seventh floor of the closing plate.
