Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood processing apparatus, and a field of sanding various wooden materials such as plywood, particle board and solid wood (for example, wood processing industry).
Of technology. In particular, the device is suitable for polishing and finishing the plywood that has been chamfered.

[0002]

2. Description of the Related Art Wood materials used for furniture, building materials, etc. are cut in advance for cutting, chamfering,
After rough processing such as router processing, many are sanded. In particular, for a plywood which has been chamfered (curved surface) using a chamfering cutter on the end face side, sanding is often performed on the end face side for polishing finishing. In this sanding process,
A veil sander device 7 as shown in FIG. 12 and a spindle sander device 8 as shown in FIG. 13 have been conventionally used.

In the former device 7, as shown in FIG. 12A, a drive pulley 71a, a guide pulley 71b and a tension pulley 71c are arranged in a polygonal shape (triangular shape, etc.).
A sanding belt 72 is stretched around this in a rotatable state. In addition, the sanding belt 7 is located between the guide pulley 71b and the tension pulley 71c.
The pressure pad 73 is arranged at a position inside the position 2. Then, while rotating the belt 72, the pad 73 is pressed to push the belt 72 to a portion (hereinafter, referred to as a “processed portion”) 751 of the wooden material 75 to be sanded. As a result, the outer peripheral surface of the belt 72 (the functional surface to which the abrasive grains are fixed) slides on the surface of the processed portion 751 to be sanded. The latter device 8 is provided with a spindle portion having a substantially cylindrical outer shape and a sand paper portion 82 wound around the peripheral surface portion (see Japanese Patent Publication No. 55-4544). Then, while the sand paper portion 82 is rotated integrally with the spindle portion, the outer peripheral surface (functional surface) of the sand paper portion 82 is pressed against the portion to be processed, and sanding processing is performed.

[0004]

However, the conventional devices 7 and 8 have the following drawbacks. That is, the former device 7 tends to be large in size because it is necessary to arrange the plurality of pulleys 71a to 71c in a polygonal shape or the like. Further, since the plurality of pulleys 71a to 71c and the pressure pad 73 are provided, the structure tends to be complicated. Further, in order to perform appropriate processing with this device 7, it is necessary to slide the surface of the processed portion 751 with the outer peripheral surface of the sanding belt 72 being even, and with a substantially average pressing force applied. Is. For this reason, as shown in FIG. 12B, it is necessary to make the shape of the pressing surface of the pressure pad 73 a shape in which the unevenness is reversed with respect to the surface shape of the processed portion 751. On the other hand, since the surface shape, outer shape, etc. of the processed part 751 differ depending on the outer shape, specifications, etc. of the final product, the user of the device 7 can make various changes corresponding to the type, size, shape, etc. of the product he or she handles. It is necessary to prepare the pressure pad 73. Therefore, the running cost of the device 7 tends to increase. In addition to this, the pressure pad 7
There is also the troublesomeness in the work such that it is necessary to replace the item No. 3.

There is also proposed a device in which several kinds of pressure pads 73 are arranged and a suitable one can be immediately selected from the several kinds of pads 73 (Japanese Patent Laid-Open No. 58-109).
263). However, in today's increasingly diversified outer shapes and shapes of final products, the diversified processed parts 751
Processing is required. Therefore, it is not possible to deal with this diversified processed portion 751 with only several types of pressure pads provided in such a device. Therefore, also in this device, it is often necessary to replace the pressure pad 73.

Further, no matter how the shape of the pressing surface of the pressure pad 73 fits the surface shape of the processed portion 751, if the plate thickness of the wooden material 75 becomes large to some extent (for example, if it exceeds 35 mm). ), It is often difficult to make the outer peripheral surface of the sanding belt 72 evenly contact the surface side of the processed portion 751. Further, in the field of wood processing, generally, strict processing accuracy such as metal processing is not required, and the dimension of each material after rough processing often has some "unevenness". Therefore, it is often difficult to accurately bring the outer peripheral surface of the sanding belt 72 into contact with the surface side of the processed portion 751. In consideration of such a situation, the processed part 751 is often divided into a plurality of regions along the plate thickness direction, and the sanding process is performed separately for each region. At that time, the wooden material 75 is passed several times along the material feeding path of the apparatus 7 (the path for carrying the wooden material 75), and the sanding process is performed for each area for each passing, and the workpiece is processed. In many cases, the processing of the entire part 751 is completed. Therefore, this type of device 7 often requires a great deal of work.

On the other hand, in the latter device 8, the structure can be simplified and the device can be easily downsized as compared with the former device 7. However, in this device 8, even if the plate thickness of the wooden material is not so large (for example, even about 15 mm), the labor for work is often large. Unlike the pressure pad 73, the device 8 does not include any member, mechanism, or the like for fitting the outer peripheral surface of the sandpaper portion 82 to the surface shape of the processed portion 751. In addition, many spindles are made of a rigid body such as metal (see Japanese Patent Publication No. 55-4544). For this reason, the wooden material 75 is often passed over the table 88 of the apparatus 8 several times, and a sanding process is performed little by little each time the wooden material 75 is passed to complete the sanding process. As described above, the conventional wood processing device represented by the devices 7 and 8 has various drawbacks in terms of the structure of the device, work efficiency, and the like.

The present invention has been made in view of the above viewpoints, has a simple structure, can be easily miniaturized, and efficiently performs sanding regardless of the thickness of the wooden material. It is an object of the present invention to provide a wood processing device that can be used.

[0009]

[Means for Solving the Problems] The present inventors have earnestly conducted research in order to achieve the above object. And FIG.
The device 9 shown in FIG. In this device 9, the abutment part 9
Plural (as long as it is two or more, it does not matter in particular) belt sanders 93a to 93c and 95a to 95c are arranged on both sides of the material feeding path 911 formed in No. 1 respectively. Further, the drive pulley P ₁ , the guide pulley P _2, and the tension pulley P _{3 included in the} belt sanders 93a, 95a, etc.
In both cases, the direction of the rotation axis can be adjusted.
By adjusting the direction of each rotation axis, the inclination of each sanding belt B ₁ , B ₂ can be adjusted appropriately. Hereinafter, an example of use of the device 9 will be described by taking a case where sanding is performed on both end surfaces of a predetermined wooden material as an example.

First, each processed portion existing on both end surfaces of the wooden material will be considered as divided into three regions along the plate thickness direction. Further, the inclinations of the sanding belts B ₁ continuously arranged on one side of the material feeding path 911 are different from each other, and any _one of the sanding belts B ₁ is in any one of the regions to be processed. So that it follows the slope of. Then, if the wooden material is passed along the material feeding path 911, each sanding belt B ₁ is a division of labor, and the sanding process of one of the processed parts is completed.

Similarly, the sanding process for each of the sanding belts B _{2 on} the other side of the material feeding path 911 is completed. However, when processing one of the end faces of the wooden material, only the belt sander on one side (for example, 93a to 93c) is moved, and the belt sander on the other side (for example, 95a to 95c) is stopped. Just go. As a result, even if the plate thickness of the wooden material is increased to some extent or the accuracy of rough processing varies, the wooden material is processed along the material feeding path 911 only once to be processed. Can be completed. Therefore, it is considered that the present device 9 can perform processing more efficiently than the above device 7.

However, in the device 9, the number of the belt sanders 93a and 95a is increased, and thus the device 7 is not used.
Instead, it is necessary to prepare a large number and a large number of types of pressure pads 97 and 98 and to use them properly. In addition, since a large number of belt sanders 93a, 95a and the like are arranged on both sides of the material feeding path 911, the belt sanders are likely to be larger than the device 7 described above. Therefore, it is difficult for the device 9 to accurately meet the demands for simplification of the structure of the device, downsizing, and the like. The inventors of the present invention have completed the present invention as a result of further earnest studies.

In the wood processing apparatus of the first aspect of the present invention, an abutment part in which a material feeding path extending in the front-rear direction is formed and a predetermined material to be sanded (hereinafter referred to as "material to be processed") are fed. A moving means for moving along the path, and a sanding means for carrying out sanding on at least one of both end surface sides along the moving direction of the workpiece moving along the material feeding path,
The sanding means has a substantially columnar outer shape, is appropriately wound depending on an external force applied to the peripheral surface portion, and is wound around the spindle portion and the peripheral surface portion in a state of orbiting around the rotation axis of the spindle portion. And a sand paper part for sanding the work material while rotating integrally with the spindle part, and a predetermined interval is provided on at least one of both sides along the front-rear direction of the material feeding path. And two or more spindle sanders arranged, and each spindle sander is appropriately rotated about a predetermined rotation axis that is substantially parallel to the front-rear direction, and the orientation of each rotation axis of each spindle section is adjusted. A translation adjuster for appropriately rotating the rotation adjusting means and the spindle sanders forward and backward along the left-right direction to adjust the intervals of the spindle parts and the feeding path along the left-right direction. If, appropriately respective spindle sander vertically, to move up and down, characterized in that it comprises a lifting adjusting means for performing adjustment of the respective spindle portion and vertically along the distance of the feed material passage.

The above "workpiece" indicates a wooden material before sanding. The type of the material is not particularly limited, and examples thereof include plywood, particle board, and solid board.
However, when this material is plywood, the significance of using this device is particularly great. In addition, the outer shape, surface shape, etc. of the portion to be processed of this "workpiece" can be variously selected. For example, a curved surface can be exemplified by a predetermined chamfering cutter. The “abutment part” may have an outer shape such as a table shape or a fixed frame shape, and the whole may be fixedly arranged at the installation location. Further, as shown in the second aspect of the present invention, the abutment portion is divided into a fixed portion that occupies one of the left side and the right side and a movable portion that occupies the other side, and the movable portion is appropriately arranged in the left-right direction. Alternatively, the width of the material feeding path along the left-right direction may be adjusted by moving the material feeding path. That is, the second invention shows an apparatus capable of easily adjusting the width of the material feeding path along the left-right direction in accordance with the width of the workpiece in the left-right direction.

The above-mentioned "moving means" is for moving the material to be processed along the material feeding path, and its form and structure are not particularly limited. For example, the third invention can be exemplified as the moving means. According to the present invention, the moving means is provided between two or more pairs of sprockets arranged in a pair in the front-rear direction of the material feeding path on the lower side of the material feeding path, and between each pair of sprockets. It is provided with each endless material feeding chain that is hung in a substantially track shape and rotates, and the upper side of each track-shaped material feeding chain is arranged substantially on the same plane as the material feeding path. A lower material feeding portion, two or more pairs of pulleys arranged in a pair in the front-rear direction of the material feeding path on the upper side of the material feeding path, and a substantially track shape between each pair of pulleys. An upper material feeding portion provided with endless material feeding belts that are hung around and rotate, and a distance between the lower side of each material feeding belt having the track shape and the material feeding path are adjusted. With the interval adjusting means, That.

As described above, since the "spindle portion" can change its outer shape according to the external force applied to the peripheral surface portion,
The sand paper part wound around this also changes its shape in response to the spindle part. Therefore, it is possible to fit perfectly to various and various external shapes of the processed portion (or the region forming a part of the processed portion) with which the spindle portion and the sand paper portion come into contact with each other. Further, the sandpaper portion is pressed toward the processed portion by the elastic force of the spindle portion. Therefore, in this device, the above-mentioned “devices 7 and 9” are used.
It is not necessary to provide a pressing member or the like such as the pressure pads 73, 97, 98 "of No. In addition, this spindle part
The whole may be elastically deformable, or only the portion around the peripheral surface portion may be elastically deformable.

Examples of the above-mentioned "sand paper portion" include a sound paper having abrasive grains adhered to the outer peripheral surface thereof and having a cylindrical shape substantially corresponding to the outer shape of the spindle portion. Further, the sand paper part includes not only a paper base material to which abrasive grains are fixed, but also a cloth base material to which abrasive grains are fixed. The number of “each spindle sander” is not particularly limited as long as two or more can be arranged on at least one of both sides along the front-rear direction of the material feeding path.
The arrangement interval can be appropriately selected.

The "rotation adjusting means" changes the inclination of the outer peripheral surface of each sandpaper portion by adjusting the direction of each rotating shaft of each spindle portion. Therefore, when the portion to be processed is divided into several regions along the plate thickness direction and the sanding process is performed, the inclination of the plurality of sand paper parts continuously arranged on one side of the material feeding path is set to each region. Can be accurately followed. Then, the sanding process is performed by the division of labor of the plurality of sand paper parts having various inclinations. The above-mentioned "translation adjusting means" adjusts the intervals of the respective spindle parts and the feeding path along the left-right direction. On the other hand, the "elevation adjusting means" adjusts the intervals of the spindle portions and the material feeding path in the vertical direction. Therefore, by the action of both the adjusting means, the outer peripheral surface of each sandpaper portion and each desired portion of the workpiece can be brought into contact with each other accurately and accurately. Various specific structures of the "rotation adjusting means", "translation adjusting means", and "elevation adjusting means" can be selected.

According to the fourth aspect of the present invention, the auxiliary abutment portion having the passage extending in the front-rear direction is arranged in front of the abutment portion in a state where the passage is arranged substantially on the same straight line as the material feeding passage. The auxiliary abutment part is arranged side by side, and the auxiliary abutment portion passes a predetermined rough material to be processed along the passage, and a predetermined position on both sides of the passage in the front-rear direction. Cut off the cutting allowances provided on both end sides along the passage direction of the roughened material, and cut the width of the roughened material in the left-right direction to the width of the sanded material in the left-right direction. Each of the circular saws to be aligned is provided. That is, on the front side of the device of the first to third invention for the purpose of performing sanding,
A "tenoner processing machine equipped with a circular saw section for cutting off the cutting allowance of the material to be roughened" is arranged. Therefore,
More efficient wood processing.

According to a fifth aspect of the present invention, in the device of the fourth aspect, the auxiliary abutment portion is at least one of both sides of the passage, and the auxiliary saw portion is more than the portion where the circular saw portions are arranged. A chamfering cutter portion for chamfering at least one of both end surfaces along the passage direction of the rough material cut off for the cutting margin is provided near the abutment portion. In this device, on the upstream side of the device of the first to third inventions,
The "tenoner processing machine having the circular saw section and the chamfering cutter section" is arranged. Therefore, wood processing can be performed even more efficiently. In addition, the "roughened material" in the fourth and fifth inventions indicates a state before roughing (cutting-off of a cutting allowance, chamfering, etc.) of the "worked material" shown in the first to third inventions. ing.

Therefore, when the grip portion 343 is operated, the spindle portion 311, and thus the sandpaper portion 312 is moved toward and away from the material feeding path 11 (workpiece) along the vertical direction.

When the first operating handle 334 is rotated in either the normal or the reverse direction, the movable plate 332 translates toward the left side or the right side. As a result, the spindle sander 31 has the worm 322,
It moves in translation along with the movable support base 35 and the like. Therefore, if the first operation handle 334 is operated, the spindle portion 311 and the sand paper portion 312 are moved in the left-right direction,
In addition, they are moved toward or away from the material feeding path 11 (material to be processed). Further, when the worm handle 324 is rotated in either the positive or negative direction, the transmission shaft 323 and the worm 322 are rotated (rotated) in the positive or negative direction as shown in FIG. In response to this, the worm wheel 321
, But rotates about the movable plate 332. At the same time, the movable support base 35 integrated with the wheel 321 and the spindle sander 31 rotate. Therefore, by operating the worm handle 324, the orientation of the drive shaft 313 of the spindle portion 311 can be adjusted. Then, the outer peripheral surface 312 of the sand paper portion 312, which is the main part of the sanding process,
The inclination of a will be adjusted.

Example of Use of Device Next, an example of use of this device will be described. In this usage example, a workpiece W as shown in FIG. 8 is sanded. The workpiece W is used as a top plate of a desk, and is a main plate portion 61 having a substantially rectangular planar shape, a back surface 61a of the main plate portion 61, and the main plate portion 61. It is composed of a front droop portion 62 attached to a portion near the edge on the left side along the longitudinal direction. In addition, FIG.
As shown in (a) and (b), both the main plate portion 61 and the front portion 62 are made of plywood in which a plurality of predetermined Lauan thin plates are laminated. Then, a part where the wood opening 61b on the left side along the longitudinal direction of the main plate portion 61 and the exposed surface (side surface) 62b of the front slant portion 62 are combined, that is, the workpiece W
Only the end face side on the left side along the longitudinal direction of is the processed portion W ₁ which is chamfered into a curved surface. However, such a chamfering process may be performed on the right end face side of the workpiece W, and the end face side may also be the processed portion W ₁ .

When the material W to be processed is made of plywood and the preprocessing is performed by the chamfering cutter, it is important to perform sanding. In this type of workpiece W, as shown in FIGS. 9 (a) and 9 (b), the thickness of the thin plate with the grain oriented in the vertical direction and the thickness of the thin plate with the grain oriented in the horizontal direction They are stuck together alternately along the direction. Accordingly, as shown in FIG. (B), the work site W ₁
Observing from the front, the long grain portions T _{1 in} which the grain is in the vertical direction and the grain portions Y _{1 in} which the grain is in the horizontal direction are alternately arranged. When the chamfering cutter is used to perform cutting on such a processed portion W ₁ , the appearance of the final product may be deteriorated, especially in the side grain portion Y ₁ , and coating as a post-process (melamine coating) This is because "burrs" that can deteriorate the finished state of () are likely to occur.

Then, the movable portion 1b is moved to the left or right to adjust the width of the material feeding path 11 to the width of the material W to be processed. Further, the interval adjusting means 23 is appropriately driven so that the interval between the "lower side of each material feeding belt 222" and the "upper side of the material feeding chain 212" corresponds to the plate thickness of the workpiece W. Let Next, the rotation adjusting means 32, the translation adjusting means 33, and the elevating adjusting means 34 of the respective sanding means 3 continuously arranged on the left side of the material feeding path 11 are appropriately operated. Then, for each spindle portion 311 and each sand paper portion 312 that constitute these sanding means 3,
While approaching or separating toward the material feeding path 11,
The inclination of each spindle unit 311 and each sand paper unit 312 is adjusted.

Specifically, as shown in FIG. 8, each sandpaper portion 312 has a portion W ₁ to be processed which passes through the material feeding path 11.
Adjust so that it touches the areas centered on different areas. Then, the seven sandpaper parts 312 shown in FIG.
Thus, the entire surface of the processed portion W ₁ is covered. In this example of use, since only the left end face side of the workpiece W is the processed portion W ₁ , the material feeding path 11
Each of the spindle sanders 31 on the right side of is moved away from the material feeding path 11 and is in a resting state. Further, each spindle unit 311 and each sand paper unit 312 used
The tilted state and the order of tilting are not limited to those illustrated in FIG. For example, the order is upward and downward from the front, but the order may be downward, upward, or upward, upward, downward, downward, and so on.

The inclination angles of the spindle portions 311 and the sand paper portions 312 are not limited to those illustrated in FIG. Further, it is not necessary to use all of the spindle sanders 31 continuously arranged on each side, and it is possible to selectively use, for example, three spindle sanders 31 and the remaining four spindle sanders 31 in a rest state. Is. After the width of the material feeding path 11 and the sanding means 3 are adjusted in this manner, the sanding means 3 on the left side and the moving means 2 are put into operation. Next, the workpiece W is inserted into the material feeding path 11 from the front side of the apparatus, and the material feeding path 1
If it is moved to the rear side along 1, the sanding process of the entire processed portion W ₁ is completed.

In the present apparatus, each spindle portion 311 changes its outer shape in accordance with the contact portion (area) of the processed portion W ₁ , and each sand paper portion 312 also changes its shape accordingly. Moreover, since the deformation of each spindle portion 311 is elastic, the elastic force of each spindle portion 311 causes
Each sandpaper portion 312 is pressed toward the contact point (area). Further, since the processing of the entire processed portion W ₁ is performed by the division of labor of each sandpaper portion 312 that is continuously arranged beside the material feeding path 11, the processed portion W _{1 is} processed.
Even if the plate thickness of the
The processing range for each 12 does not increase. Therefore, a good finished state can be obtained even if the workpiece W has a large plate thickness and the rough machining accuracy of the workpiece W ₁ varies among products.

Further, since the seven sand paper parts 312 work together, the work W can be completed by passing the work W along the material feeding path 11 only once. Therefore, the processing efficiency of sanding can be improved. Furthermore,
Since the pressing member (pusher pad) 73 and the like provided in the conventional belt sander device 7 and the like are not required, the running cost of the device can be reduced and the labor for use can be reduced.

Further, unlike the device 7 and the like, it is not necessary to arrange a plurality of pulleys 71a and the like on both sides of the material feeding path 11, so that the device can be downsized and the structure can be simplified. You can Further, the load of the operator can be reduced also in that the work W can be automatically fed by using the moving means 2. Further, the adjustment of each sanding means 3 is performed by the rotation adjusting means 32, the translation adjusting means 33, and the elevation adjusting means 3.
4 can be carried out easily, and the device can be easily handled. In addition to this, since the width of the material feeding path 11 can be changed instantaneously, it is possible to immediately respond to a setup change.

In this example of use, as shown in FIGS. 8 and 10, not only the curved surface of the workpiece W but also the curved upper and lower surfaces of the workpiece W. The area surrounding the area (the area indicated by the symbols F ₁ and F ₂ in FIG. 10) is also the processing range. Therefore, in this example of use, "burrs", which are so-called "corners", which are likely to occur in this portion can be reliably removed. In addition, in this use example,
As shown in FIG. 10, a plurality of sound paper parts 312 having similar inclination angles overlap each other in their processing ranges. Therefore, a good finished state can be obtained more reliably. In particular, the portions existing above and below the processed portion W ₁ having a large curvature and easily causing “burrs” are respectively 3
It has a great significance in that the two sound paper parts 312 are processed redundantly.

Each of b is movable in the left-right direction while being biased toward the passage 511 by predetermined springs K ₁ and K ₂ . Further, the shifting member 518 is arranged substantially parallel to the right frame portion 516b, and the receiving portion 518b having a substantially L-shaped cross section is directed toward the passage 511 side. Then, when the width-adjusting handle 518c provided on the side away from the passage 511 is rotated in either the normal direction or the reverse direction, the receiving portion 518b approaches or separates from the passage 511. Therefore, if the width-adjusting handle 518c is operated according to the width of the material to be roughened in the left-right direction, the receiving portion 5
The distance between 18b and each alignment roller 517a, 517b can be adjusted.

In this processing machine, this roller 517 is used.
The width of the passage 511 is fixed because it includes a and 517b and the approaching member 518. However, like the material feeding path 11 of the sanding machine, the width of the passing path 511 can be appropriately adjusted. On the contrary, the width of the material feeding path 11 of the sanding machine is fixed, and this machine also has the same rollers 517a, 517b as described above.
The pulling member 518 may be arranged. Passing means 5
2 is configured similarly to the moving means 2 of the sanding machine.

The cut-off means 53a and 53b are arranged near the middle of the passage 511 and on both sides. These are all, two sets of circular saw which rotates at a predetermined drive motor M ₅ ~M ₈ (531a and 5
32a, 531b and 532b) are arranged with their axes of rotation displaced vertically. That is, the rotating shafts of the circular saws 531a and 531b arranged on the upper side are the passages 511.
Circular saws 532a, 5 located above and below
The rotation axis of 32b is located below the passage 511.
And upper and lower circular saws (531a and 532a, 531b)
And 532b) are intersecting with each other at a height substantially the same as that of the passage 511, while maintaining a predetermined distance in the front and rear.

The cut-off means 53a and 53b are also provided.
At least one of them can be appropriately translated in the left-right direction (a specific mechanism is not shown). This is for adjusting the interval between the cut-off means 53a, 53b according to the width of the material to be roughened in the left-right direction. The chamfering means 55 is composed of two chamfering cutters 551 and 552 arranged on the left side on the rear side of the passage 511. These cutters 551 and 552 rotate around the same drive shaft and perform a desired chamfering process on the material to be roughened that has passed through the cut-off means 53a and 53b.

The number of chamfering cutters 551, 552 constituting the chamfering means 55 is not particularly limited, and the tooth profile of each chamfering cutter 551, 552 depends on the specifications of the final product,
Various selections will be made according to the shape and the like. Further, the chamfering cutters 551 and 552 may be arranged on both sides of the passage 511. Furthermore, the tenoner processing machine does not include the chamfering means 55, and the cutting-off means 53 is provided.
It may be configured with only a and 53b. Further, in addition to the chamfering means 55 or instead of the chamfering means 55, other roughing means such as a router processing means and a groove forming machine may be provided.

In this apparatus, from the front side of the tenoner machine, the rough-worked material having a predetermined cutting margin is inserted at both end sides. Then, while passing the rough-worked material along the passage 511, the cutting of the cutting allowance and the chamfering are performed. As a result, the material to be roughened is the same as in the first embodiment.
The "workpiece W" indicated by. Next, the material W to be processed is fed into the material feeding path 11 and subjected to the sanding processing shown in the first embodiment. Therefore, according to the present apparatus, the roughing process and the sanding process can be performed continuously, so that the wood processing efficiency can be increased. Further, as described above, since the sanding machine can be downsized, even if the sanding machine and the tenor machine are provided side by side as shown in the present embodiment, a large space is not required. It has great significance in terms.

The present invention is not limited to those shown in the above-mentioned embodiment, and various modifications, etc., within the scope of the present invention are given according to the purpose and application. You can That is, a predetermined scale plate or the like can be arranged on each of the adjusting means 32 to 34 included in the sanding means 3. In this case, the adjustment of the device for each setup change can be performed more efficiently and quickly. Moreover, in each of the above-described embodiments, it is preferable that the chamfering direction and the sanding direction are opposite to each other with respect to the traveling direction of the workpiece W. For example, when the chamfering cutter cuts into the workpiece W in the downcut direction, the spindle sander preferably slides in the uppercut direction with respect to the workpiece portion W ₁ . Furthermore,
When the plate thickness of the workpiece W does not increase, the sanding process may be performed using only the single spindle sander 31.
