Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a batch-type wood peeling machine used for peeling construction wood and for peeling the bark in a pre-process of manufacturing wood chips.

〓Conventional technology〓 Generally speaking, when wood is used for construction purposes or for making chips, it is first necessary to remove the bark.

Many conventional wood peeling machines are continuous type, and most of the wood peeling machines currently in use are of the type developed earlier by the present inventor.

This continuous wood peeling machine has a wood peeling tank formed by a receiving side plate and a feeding side plate, and an opening is formed along the longitudinal direction at the bottom of the tank, and a number of peeling blades are attached to the outer periphery to close the opening. A rotating body is inserted, and one end along the length of the wood peeling tank is used as a wood input section, and the other end is used as a wood removal section (Japanese Patent Publication No. 61-46282).

This continuous wood debarking machine has various effects such as extremely high debarking efficiency, simple structure, and low power cost.

However, this continuous wood peeling machine has a problem in that the apparatus becomes long and large because it feeds the wood while peeling it in the longitudinal direction. For this reason, if the factory space is limited, such as small-scale chip manufacturers, or if the wood is delivered to a paper mill without the bark being made into chips, the pulp is made directly from the logs.
There was a desire to develop a compact batch-type wood peeling machine that would be effective when producing small quantities of GP wood.

〓Problems to be Solved by the Invention〓 The present invention has a small device, requires little installation space, has a simple structure, and is inexpensive.Moreover, it can peel the skin uniformly, has excellent peeling efficiency, and can prevent wood from getting caught. We provide a batch-type wood peeling machine that prevents large forces from being applied to the peeling rotor and side plates, thereby preventing equipment damage and motor overload, improving the durability of the equipment, and expanding processing capacity. It is something to do.

〓Means for Solving the Problems〓 The present invention has the upper part of a wood peeling tank configured with a feeding side plate supported so as to be openable and closable on one side and a receiving side plate on the other side serving as a wood input portion, and the feeding side plate is opened. A peeling rotary body having a portion serving as a wood removal portion, an opening formed along the longitudinal direction at the bottom of the wood peeling tank, and a number of peeling blades protruding from the outer periphery, the upper portion of which is the opening. The first gist is that the left and right side plates at the ends of the wood peeling tank in the longitudinal direction are tilted or curved so that the interior of the wood peeling tank expands upward. That is.

Furthermore, in the batch-type wood peeling machine having the above configuration, the feed side plate is supported by a sliding mechanism so as to be able to be opened and closed vertically, a shutter is provided below the feed side plate, and a comb is provided at the tip of the feed side plate that protrudes into the wood peeling tank. The second point is that a tooth structure is formed.

〓Operation〓 The batch-type wood peeling machine of the present invention opens the opening of the wood peeling tank by sequentially feeding the wood into the input portion of the wood peeling tank while rotating the peeling rotor toward the receiving side plate. The wood is scraped up by a peeling blade protruding from a peeling rotary body whose upper part is inserted so as to close the wood, and the wood is peeled by repeating the rotation while rotating in the wood peeling tank.

In addition, the left and right side plates are sloped or curved so that the inside of the wood peeling tank expands upward.
Even if the wood gets caught between the peeling blade and the left and right side plates, the wood will slide on the surfaces of the left and right side plates and be lifted upwards and escape, preventing damage to the device and overloading the motor.

The wood that has been completely peeled is discharged from a take-out portion formed in the open portion by opening the feed side plate.

In addition, this take-out part is supported so that the feed side plate can be rotated or moved up and down by a sliding mechanism.If the feed side plate is rotatably supported, when the feed side plate is open, the feed side plate itself becomes a shooter, and it can also be moved up and down. The supported items are carried out from a separate shooter.

A peeling rotating body 10 is provided at the bottom of this wood peeling tank 1, and the upper part of its outer periphery is partially inserted so as to close the bottom opening 4.

As shown in FIG. 2, this peeling rotary body 10 has a large number of peeling blades 12 each having a stair block shape on the outer peripheral surface of a pipe shaft 11, arranged in an inverted V-shape, distributed from the center to the left and right, for example. are doing.

Further, round bar-shaped shafts 13, 13 are attached to both ends of this peeling rotary body 10, and this shaft 1
3 is supported by a bearing 14, and one shaft 1
A motor 16 is connected to the motor 3 via a speed reducer 15.

Furthermore, the right side plate 17A and the left side plate 17B, which serve as side walls at both ends along the longitudinal direction of the wood peeling tank 1, are arranged so that the interior of the wood peeling tank 1 expands upward from near the top of the peeling rotary body 10. It is sloping.

Further, as shown in FIG. 3, a block-shaped peeling blade 12 protruding from the peeling rotary body 10 is attached to the edges of the openings 4 of the feed side plate 2 and the receiving side plate 3 that constitute the wood peeling tank 1. The comb tooth grooves 18 are formed corresponding to the pitch so that the comb teeth do not overlap.

Further, the feed side plate 2 has shafts 5, 5 at both ends of the lower part in which the comb tooth grooves 18 are formed, and the shaft center thereof is located at the comb tooth groove 18.
The shafts 5, 5 are supported by bearings 19 provided on the support frame 6, and are designed to rotate about the bearings 19 as rotation fulcrums.

Further, as shown in FIG. 2, a motor 20 and a speed reducer 21 are attached to the upper side of the wood peeling tank 1, and the feed side plate 2 is connected via a gear 22 and a chain 23.
It is connected to the opening/closing mechanism 24 of.

This opening/closing mechanism 24 consists of gears 22, 22 attached to the right side plate 17A and left side plate 17B at the top of the wood peeling tank 1, as shown in FIG. 2, and chains 23, 23, as shown in FIG. has been done.

One end of the chains 23, 23 is connected to both ends of the upper part of the feeding side plate 2, and weights 25, 25 are connected to the other end.
is suspended, and the feed side plate 2 is opened and closed by the movement of the chains 23, 23.

In the figure, 26 is a conveyor for carrying out the peeled bark, and 27 is a bark guide.

Next, the operation of the batch type wood peeling machine having the above structure will be explained.

The motor 16 is driven to rotate the peeling rotary body 10 in the direction of the arrow toward the receiving side plate 3 as shown in FIG.

In this state, when the wood 7 is sequentially fed into the wood stripping tank 1 from the center along the longitudinal direction of the input section 8, the stripping blades 12 are arranged in an inverted V shape from the center to the left and right. By the rotation of the peeling rotary body 10, the wood 7 is distributed to the left and right in the wood peeling tank 1 and spread uniformly in the tank. In addition, the left and right side plates 17A and 17B along the longitudinal direction of the wood peeling tank 1 are inclined as shown in FIG. 2 so that the interior of the wood peeling tank 1 expands upward, making it easy to input the wood 7. In addition, the processing capacity is large and a large amount of wood 7 can be processed.

At this time, as shown in FIG. 1, the peeling rotary body 10 whose upper part is inserted so as to close the bottom opening 4 of the wood peeling tank 1 is rotating in the direction of the arrow, so that the wood 7
is scraped up while being peeled off by a block-shaped peeling blade 12 protruding from the surface of the peeling rotary body 10. The scraped up wood 7 is received by the receiving side plate 3 and turned over, rotates inside the wood peeling tank 1 in the opposite direction to the peeling rotary body 10, is sent by the feed side plate 2, where it falls due to its own weight, and the wood is It continues to revolve and roll while rotating inside the peeling tank 1.

Furthermore, as shown in FIG. 2, the left and right side plates 17A and 17B are sloped so that the inside of the wood peeling tank 1 expands upward, so one side of the wood 7 slides up the slope. By repeating the downward movement, the wood 7 as a whole rolls while reciprocating along the longitudinal direction, and the entire surface is uniformly peeled.

Further, at this time, the wood 7 may be caught between the skinning blade 12 protruding from the skinning rotary body 10 and the left and right side plates 17A, 17B. In this case, as shown in FIG. 2, the ends of the wood 7 that are in contact with the left and right side plates 17A, 17B slide on the inclined surfaces of the left and right side plates 17A, 17B, and are lifted upwards as shown by the arrows and escape. I can do it.

As a result, the peeling rotary body 10, the left and right side plates 17A,
Damage to the device and overload of the motor 16 can be prevented without applying a large force to 17B.

When the barking of the wood 7 is completed, the state is checked from the top of the wood stripping tank 1, and the motor 20 of the opening/closing mechanism 24 is rotated. As a result, when the chain 23 is moved by the gear 22 and the feed side plate 2 is rotated downward as shown by the imaginary line as shown in FIG. The feed side plate 2 itself serves as a shutter 29, and the wood 7 that has been completely stripped of its bark is slid from the shutter 29 and carried out to the outside.

In this case, a weight 25 is attached to the opening/closing mechanism 24 of the feed side plate 2 to balance the weight with the feed side plate 2, so the output of the motor 20 may be small.

In the above embodiment, the left and right side plates are inclined, but a structure in which the inside of the wood peeling tank 1 is curved so as to expand upward may also be used.

FIG. 4 shows another embodiment of the present invention, in which the upper side of the wood peeling tank 1 is integrally constructed in the shape of a rectangular tube, and the feed side plate 2 has a short structure with only an inclined surface. Supported to open and close freely.

In this case, the left and right side plates 17A and 17B along the longitudinal direction of the wood peeling tank 1 are inclined as shown in FIG. Left and right side plates 17A, 17B
When the wood 7 is caught between the two, the wood 7 slides on the surface and escapes.

In the above structure, only the lower feeding side plate 2, which serves as the extraction section 9 for the wood 7, is rotated, so it is smaller and lighter in weight than the large feeding side plate 2 shown in FIG. 1, so the opening/closing mechanism 24 is simplified. Moreover, since the upper side of the wood peeling tank 1 is integrally formed into a rectangular cylindrical shape, the strength is also improved.

FIG. 5 shows another embodiment of the present invention, in which the upper side of the wood peeling tank 1 is integrally constructed in the shape of a rectangular tube, and the feed side plate 2 has a short structure with only an inclined surface. It is supported so that it can be raised and lowered freely.

This feeding side plate 2 is provided with lifting guides 28, 28 at both ends along the longitudinal direction, and is lifted and lowered by being guided by the lifting guides 28, 28 by a chain 23,
When the feed side plate 2 is raised, a take-out portion 9 is formed in this open portion.

Further, a shooter 29 is provided below the feed side plate 2, and a comb tooth groove 18 is formed at the tip protruding into the wood peeling tank 1, and the lower end of the feed side plate 2 is in contact with the upper surface of the front side of the comb tooth groove 18. We are starting to come into contact with each other.

In this case, the left and right side plates 17A and 17B along the longitudinal direction of the wood peeling tank 1 are inclined as shown in FIG. Left and right side plates 17A, 17B
When the wood 7 is caught between the two, the wood 7 slides on the surface and escapes.

The above structure is rotatably supported by a shaft 5.
There is no rotating mechanism like the feed side plate 2 shown in FIGS. 1 and 4, which receives force from the chain 23, and the elevating guide 28 receives the force applied to the feed side plate 2, resulting in excellent durability. Since they are formed separately, the shape can be selected according to the optimal delivery condition of the wood 7.

In the present invention, the comb tooth grooves 18 may be formed at the lower end of the feed side plate 2, contrary to what is shown in FIG. 5, and the lower shutter 29 may be formed of a flat plate without the comb tooth grooves 18.

Furthermore, in the above embodiment, one skinning rotary body 10 is arranged, but two or more skinning rotary bodies 10 may be arranged in parallel, and the mounting positions of the skinning rotary bodies 10 arranged in parallel may be at the same height or above and below. It may be shifted to

Further, in the present invention, an auxiliary rotor may be attached between the feeding side plate 2 and the receiving side plate 3, which are the side walls of the wood peeling tank 1, to further promote the rotation of the wood 7.

Further, the shape of the peeling blade 12 is not limited to one in which the rising part on one side is stepped. If the peeling rotary body 10 is rotated forward or backward depending on the operating condition, the peeling blade 12 may have a step-like shape on both sides. The most suitable shape may be selected depending on the wood material, etc.

Furthermore, the arrangement shape of the peeling blades 12 is similar to that of the pipe shaft 1.
The peeling blades 12 are not limited to those arranged in an inverted V-shape from the center to the left and right on the outer peripheral surface of the blade 1, but may be V-shaped or spiral, and a plurality of peeling blades 12 may be arranged in parallel. Furthermore, the peeling blade 12 is not limited to being fixed to the outer circumferential surface of the pipe shaft 11 by welding, but may be detachably joined with bolts.

Effects of the Invention As explained above, according to the batch-type wood peeling machine according to the present invention, the device is small, requires little installation space, has a simple structure, and is inexpensive.

Furthermore, since the left and right side plates are inclined or curved along the longitudinal direction so that the interior of the peeling tank expands upward, even if wood is caught between the peeling blade and the left and right side plates, the surfaces of the left and right side plates will not be removed. It slides and is lifted upwards and escapes, and no large force is applied to the peeling rotor or left and right side plates, which prevents damage to the equipment and overload of the motor, improving durability, and making it easy to load and process wood. Capacity can also be expanded.
