DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an uneven board, and more particularly, to a straight board which reliably removes "unevenness" such as warp or twist of a work material such as wood. It is related to an uneven board from which materials can be obtained.

[0002]

2. Description of the Related Art For example, when a material to be processed such as a long piece of wood is dried, moisture contained in the material evaporates.
As shown in FIG. 1, the material 8 to be processed is warped or twisted called "unevenness". Therefore, in order to use the work material 8 having “unevenness” as a woody material, it is necessary to remove the “unevenness” with a so-called planer and finish the surface smoothly.
The planing machine is provided with a cutting mechanism provided with a rotary cutting body, and a lower surface of a work material placed on the surface plate.
After positioning the cutting mechanism at a position where a required cutting amount is cut from the (surface), the work material is horizontally transferred from the upstream side in the material transfer direction toward the cutting mechanism, so that the lower surface of the work material is reduced. Only the required amount is cut.

FIG. 20 schematically shows an example of an automatic planer for cutting the lower surface of a work material having the above-mentioned “unevenness”. The lower surface 8b is placed with the lower surface 8b facing the surface plate 61, and in the process of cutting the lower surface 8b with
Is transported from above while being pressed against the surface plate 61 by a transport mechanism composed of a plurality of material feeding rollers 63.

[0004]

In the planer board 60 constructed as described above, the material 8 is fed to the material feeding roller 6 in the process of cutting the lower surface 8b of the workpiece 8 by the planer cylinder 62.
Since the workpiece 3 is pressed from above, there is a disadvantage that "unevenness" of the workpiece 8 is temporarily corrected. That is, the material 8 to which the pressing from the material feeding roller 63 is released after the cutting of the lower surface 8b has a problem that the “irregularity” similar to that before the cutting is restored again (the machining on the left side of FIG. 20). See material 8). Therefore, as a means for transferring the material 8 to be processed, an endless belt wound around a pair of rotating bodies separated in the material transferring direction or a roller made of an elastic body such as sponge rubber is allowed to move up and down in a required width. It has been proposed that the transfer means be moved while moving the transfer means up and down in response to a change in the position of the upper surface caused by "unevenness" of the work material 8 placed on the surface plate 61 by using the means for performing the work. . However, in order to apply the feeding force to the material 8 to be processed by any transfer means,
It is necessary to apply a required pressing force to the material 8 from above, and it is inevitable that "unevenness" is corrected, and the fundamental solution has not been reached.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problems suitably, and is intended to transfer the "unevenness" of the material to be processed without correcting it. It is an object of the present invention to provide a new uneven planing board capable of reliably removing "unevenness".

FIG. 1 is an overall perspective view schematically showing a flattening board according to a preferred embodiment of the present invention, and FIG. 2 is a plan view of the flattening board. As shown in FIG. 1 and FIG. 2, an uneven board 1 according to the embodiment.
Numeral 0 denotes an unevenness measuring unit 12 for measuring the maximum bending amount A of the “unevenness” of the material 8 to be processed, and is disposed on a side of the unevenness measuring unit 12 and disposed downstream in the material transfer direction. Front table 14 which moves up and down while maintaining a horizontal posture with respect to the planed cylinder 16 which is a rotated cutting body, and the front table 14, the planed cylinder 16 and the material discharge section 2 arranged downstream thereof.
And a feed slider 18 provided with a plurality of clamp mechanisms 42 that can reciprocate along the slide beam 30 extending between the feed beam 18 and the workpiece 8 from the width direction. Therefore, each component will be described.

And two conveyors 22. Each of the conveyors 21 and 22 is synchronously driven by driving means (not shown). Further, the downstream end of the first conveyor 21 and the second conveyor 2
As shown in FIGS. 4 and 5, between the upstream end of
Two detectors 23, 23 for measuring the maximum bending amount A of the "unevenness" of the material 8 to be processed are arranged at a required interval in a direction orthogonal to the material transfer direction. As the detector 23, an existing means such as a laser sensor is suitably employed.

In the detectors 23, 23 shown in FIGS.
As shown in FIG. 4, when the workpiece 8 is transferred from the first conveyor 21 to the second conveyor 22, the detectors 23, 2
3 and a reference surface 8b
(Transfer surfaces of the conveyors 21 and 22) are continuously measured. That is, by continuously measuring from the front end to the rear end of the lower surface 8b of the material 8 to be processed, it is possible to detect vertical warpage and bending over the longitudinal direction. The measurement data from the detectors 23 and 23 are sent to the processing unit in the control box 24 shown in FIG.
(Not shown) and is subjected to a calculation process to set the maximum bending amount A of the workpiece 8 in the vertical direction.
Since the two detectors 23 and 23 individually measure from the front end to the rear end at both ends in the width direction intersecting the transfer direction of the work material 8, it is possible to detect the twist of the work material 8 and the like. It is possible to more accurately measure the maximum bending amount A.

On one side of the second conveyor 22, two pushers 25, 25 orthogonal to the material transfer direction are disposed in parallel with each other at a distance in the material transfer direction.
The workpieces 8 placed on the second conveyor 22 are transferred in parallel to the front table 14 by extending the rods 25a, 25a of 5, 5 toward the other side. (See FIG. 16).

(Regarding the front table) The unevenness measuring section 12
The front table 14 on which the workpiece 8 is transferred from the conveyor 22 via the pushers 25, 25 is disposed on the side of the second conveyor 22 where the pushers 25, 25 are not disposed. . The front table 14 is disposed above a frame 26 installed in parallel with the unevenness measuring unit 12 and is always kept in a horizontal posture. Further, on the downstream side from the disposition position of the front table 14, a rotary shaft 27 having an axis perpendicular to the material transfer direction is disposed horizontally,
The planer body 16 is mounted on the rotating shaft 27 and is driven to rotate by a motor 28.

The front table 14 is raised and lowered in a horizontal position with respect to the plane 16 by a lifting mechanism (not shown) driven and controlled by a command from a control unit (not shown) in the control box 24. It is configured to move. The front table 14 corresponds to the maximum bending amount A of the work material 8 calculated based on the measurement data of the detectors 23 and 23 with reference to the highest position in the rotation locus of the blade edge of the planer cylinder 16. Cutting amount B set
It descends by the minute (see FIG. 15). That is, the cutting amount B is set to be larger than the maximum bending amount A. If the workpiece 8 placed on the front table 14 is transferred horizontally toward the planer cylinder 16, “unevenness” is obtained.
Can be completely removed. The front table 14
As the elevating mechanism, a structure in which a means consisting of a combination of a screw shaft and a nut or a rack and a pinion is driven by a motor to elevate and lower the front table 14 or directly elevate and lower the front table 14 by a cylinder is appropriately adopted. It is possible.

(About the Feed Slider) In the uneven planer board 10 of the embodiment, the feed slider 18 for horizontally transferring the work material 8 placed on the front table 14 toward the planer cylinder 16 is moved to the front table 14 and the planer. Torso 16
In addition, an upper portion of the material discharge section 20 is provided so as to be reciprocally movable in the material transfer direction. That is, as shown in FIGS. 1 to 3, on the opposite side of the unevenness measurement unit 12 with the front table 14 interposed therebetween, the material transfer direction extends over the side of the front table 14, the planer barrel 16, and the material discharge unit 20. A slide beam 30 is arranged in parallel, and the feed slider 18 is movably arranged on the slide beam 30. As shown in FIG. 7, a pair of guide rails 31, 31 extending parallel and horizontally in a vertical relationship are disposed on a front end surface of the slide beam 30 facing the front table 14. A plurality (five in this embodiment) of moving bodies 40 constituting the feed slider 18 are slidably disposed on the slide 31 via sliders 32, 32. Each moving body 40 is configured to extend horizontally above the front table 14 and move integrally with the connecting rod 41 extending parallel to the guide rail 31 (see FIG. 6). . Each moving body 40 is connected to the connecting rod 41 so as to be adjustable in position, and the moving bodies 4 adjacent to each other according to the length dimension of the material 8 to be processed.
The interval of 0,40 can be adjusted.

As shown in FIG. 3, a pulley 34 connected to a motor 33 disposed at a downstream end of the slide beam 30 and a pulley 35 disposed at a position of the slide beam 30 located upstream of the planer cylinder 16. An endless belt 36 is wrapped therebetween. A moving body 40 located on the most downstream side is joined to the endless belt 36 via a belt joining plate 37. Therefore, by driving the motor 33 to rotate in the forward and reverse directions, the moving body 40 is driven by the endless belt 36. All the moving bodies 40 (feed sliders 18) reciprocate along the slide beam 30 (see FIGS. 17 to 19).

Each of the movable bodies 40 is provided with a clamp mechanism 42 capable of gripping and releasing the workpiece 8 placed on the front table 14 from the width direction. Since the basic configuration of each clamp mechanism 42 is the same, the configuration of the clamp mechanism 42 disposed on the moving body 40 located on the most downstream side will be described. This clamp mechanism 42
As shown in FIG. 7, a first clamp body 43 located close to the slide beam 30 and a second clamp body located near the second conveyor 22 and movable close to and away from the first clamp body 43. 44, and an air cylinder 45 as driving means for moving the second clamp body 44 back and forth.

As shown in FIGS. 7 to 9, a slide rail 46 is provided on the side end surface of the moving body 40 so as to extend horizontally intersecting with the material transfer direction, and is slidably provided on the slide rail 46. The first plate 4 is attached to the first slider 47 provided.
The first clamp body 43 is disposed vertically via the movable member 8 and is configured to be movable in a direction intersecting the material transfer direction. A stopper 49 having a groove 49a of a required width with which the upper part of the first clamp body 43 is engaged is attached to an upper part of a side end face of the moving body 40 where the slide rail 46 is provided. The first clamp body 43 can move only within the range of 49a. The first clamp body 43 is configured so as to be positioned and fixed to the stopper 49 via required means. In the embodiment, the first clamp body 4 in the most upstream clamp mechanism 42 and the most downstream clamp mechanism 42 in the material transfer direction is used.
3, 43 are positioned and fixed to stoppers 49, 49, and both first clamp bodies 43, 43 are set to be reference positions.

In the vicinity of the lower end of the first clamp body 43,
As shown in FIG. 10 in an enlarged manner, a set screw 50 as an engaging portion whose tip is formed at an acute angle is disposed with its tip protruding toward the second clamp body 44. The tip of the screw 50 directly contacts the side surface 8a of the workpiece 8.

The second clamp body 44 is rotatably mounted on a second plate 52 mounted on a second slider 51 slidably mounted on the slide rail 46 via a support shaft 53. In FIG. 7, it can freely rotate in the clockwise direction, but in the counterclockwise direction, the rotation is restricted at a position in contact with the locking piece 54. The second clamp body 44 is set such that the lower end thereof substantially coincides with the lower end of the first clamp body 43 in the inclined state in contact with the locking piece 54. In the vicinity of the lower end of the second clamp body 44, as shown in an enlarged view in FIG. 10, a set screw 50 as an engaging portion having a sharply formed front end protrudes the front end toward the first clamp body 43. It is arranged in the state,
The tip of the set screw 50 directly contacts the side surface 8a of the workpiece 8.

When transferring the workpiece 8 from the second conveyor 22 to the front table 14, the pusher 2
When the work material 8 pushed by 5, 25 contacts the second clamp body 44, the second clamp body 44 rotates clockwise in FIG. 7 to allow the work material 8 to move. Have been. Then, when the workpiece 8 is separated from the second clamp body 44, the second clamp body 44 is rotated downward by its own weight and is locked and held at a position where it contacts the locking piece 54.

The upper part of the first clamp body 43 has a structure shown in FIG.
As shown in the figure, a bottom side of an air cylinder 45 parallel to the slide rail 46 is provided, and a rod 45a of the air cylinder 45 is provided on a second plate 52 on which the second clamp body 44 is provided. It is connected to the connection plate 55. Therefore, the rod 45 of the air cylinder 45
When a is urged in the extending direction, the first clamp body 43 and the second clamp body 44 move away from each other. However, after the movement of the first clamp body 43 is restricted by the stopper 49, the second clamp body 43 moves away from the clamp body 43. When the rod 45a of the air cylinder 45 is urged in the retracting direction, the first clamp body 4
3 and the second clamp body 44 move close to each other, but after the movement of the first clamp body 43 is restricted by the stopper 49, the second clamp body 43
Moves closer. Then, as the two clamp bodies 43 and 44 relatively move close to each other, the work material 8 located between the two clamp bodies 43 and 44 faces the set screws 50 and 50 as shown in FIG. It is gripped from the width direction while being in contact with the side surfaces 8a, 8a.

In the clamp mechanisms 42, 42 located at the most downstream side and the most upstream side, the first
Since the clamp bodies 43, 43 are positioned and fixed to the stoppers 49, 49, when the air cylinder 45 is biased forward and backward,
The second clamp bodies 44, 44 move toward and away from the first clamp bodies 43, 43 on the fixed side. On the other hand, in the other three clamp mechanisms 42 located between the most downstream and the most upstream clamp mechanisms 42, the first clamp body 43 can move within the range of the groove 49 a in the stopper 49. Therefore, when the workpiece 8 is curved in the width direction, the first material is bent in accordance with the curvature.
By moving the clamp body 43 close to the side surface 8a of the material 8, the workpiece 8 can be gripped without being corrected in the width direction (see FIG. 11). In actual use, the clamp mechanisms 4 located at the most downstream side and the most downstream side
It is desirable that the first and second clamp bodies 43, 43 be fixed at substantially the center of the groove 49a. That is, when the first clamp bodies 43, 43 that are positioned and fixed are set as reference positions, the other first movable clamp bodies 43 that are set to be movable.
Can move back and forth with respect to the reference position, and can correspond to the bending of the workpiece 8 in the width direction.

The upper surface level of the material discharge section 20 disposed downstream of the planer cylinder 16 is set at a position slightly lower than the highest position in the rotation locus of the cutting edge of the planer cylinder 16. It is configured not to interfere with the transferred work material 8 after cutting. A roller conveyor (not shown) is provided in the material discharge section 20 so that the material 8 after cutting is discharged laterally from a cutting line by the planer cylinder 16.

[0023]

Next, the actual use of the thus-configured uneven planer according to the present embodiment will be described. The work material 8 from which "unevenness" is to be removed is first loaded and loaded on the first conveyor 21 in the unevenness measuring section 12, but in this step, a manual loading method or an automated material loading device (FIG. (Not shown) is provided on the upstream side and automatically carried in.

In a state where the first conveyor 21 and the second conveyor 22 in the unevenness measuring section 12 are stopped, the workpiece 8 is placed on the first conveyor 21 with the cutting surface 8b facing down (see FIG. 12). . When the placing of the work material 8 on the first conveyor 21 is completed, the work material 8 is moved by the driving means (not shown) to the downstream side so that the work material 8 is detected by the detector 23. ,
23 and transferred to the second conveyor 22.
At this time, as shown in FIG. 13, the detectors 23, 23 continuously measure the distance from the reference plane to the lower surface 8b of the moving workpiece 8, and send the measured data to the processing unit in the control box 24. input. The material to be processed 8 is the second conveyor 22
The conveyors 21 and 22 stop at the point when they are completely transferred to the second conveyor 22, and the workpiece 8 temporarily stops on the second conveyor 22 and waits (see FIG. 14).

In the processing section in the control box 24, the maximum bending amount A in the vertical direction of the workpiece 8 is calculated, and the cutting amount B which is slightly larger than the maximum bending amount A is set. You. An elevating mechanism (not shown) is driven and controlled by a command from a control unit in the control box 24,
As shown in FIG. 15, the front table 14 is moved up and down,
The upper surface level is stopped and positioned at a position lower than the highest position in the rotation locus of the blade edge of the planer cylinder 16 by the cutting amount B.

After confirming that the positioning of the front table 14 has been stopped, as shown in FIG.
Of the rods 25a, 25
“a” extends, and the material 8 placed on the second conveyor 22 is pushed out to the front table 14 side. At this time,
The feed slider 18 stands by above the front table 14, and in each clamp mechanism 42, the second clamp body 44 faces the position farthest from the first clamp body 43. Therefore, the pusher 2
The work material 8 extruded by 5 and 25 moves while being rotated while pressing and rotating the second clamp body 44 held in contact with the locking piece 54 and is transferred to the front table 14.
When the work material 8 is separated from the second clamp body 44, the clamp body 44 is rotated downward by its own weight and is locked and held at a position where it contacts the locking piece 54.

When the transfer of the workpiece 8 to the front table 14 is completed, the air cylinder 4
5 are simultaneously urged in the direction of retracting the rod 45a. In the clamp mechanisms 42, 42 located at the most downstream side and the most upstream side in the material transfer direction, the first clamp bodies 43, 43 are positioned and fixed to the stoppers 49, 49 as described above. First by force
The second clamp bodies 44, 44 are provided for the clamp bodies 43, 43.
The workpiece 8 transferred to the front table 14 is moved to a position where one side surface 8a abuts on the first clamp bodies 44. Then, as shown in FIG. 7, a set screw 5 between the first clamp body 43 and the second clamp body 44 is formed.
The workpiece 50 is gripped from the width direction in a state where the vertical movement is completely restricted by the abutment of 0,50 with the side faces 8a, 8a of the workpiece 8. In addition, the clamp mechanisms 42, 42 located at the most downstream side and the most upstream side are the moving bodies 40,
The position of the workpiece 40 is adjusted with respect to the connecting rod 41 so that the workpiece 8 is positioned so as to grip the vicinity of both ends in the longitudinal direction.

The other three clamp mechanisms 4 located between the most downstream and the most upstream clamp mechanisms 42, 42
In 2, the first clamp body 43 and the second clamp body 44 move close to each other by the bias of the air cylinder 45, and the set screws 50, 50 of the two clamp bodies 43, 44 are moved to the side surfaces of the workpiece 8. The material 8 is gripped from the width direction in a state where the material 8 is in contact with 8a. In the three clamp mechanisms 42, the first clamp body 43 is
a, the first clamp body 43 moves close to the side surface 8a of the material 8 in accordance with the curvature of the workpiece 8 that is curved in the width direction. Thus, the workpiece 8 can be gripped without being corrected in the width direction (see FIG. 11).

As shown in FIG. 17, when the gripping of the workpiece 8 by all the clamp mechanisms 42 is completed, the motor 33 is driven, and the feed slider 18 moves downstream along the slide beam 30. Lower surface 8b of workpiece 8 transferred horizontally by feed slider 18
Is cut by a cutting amount B in the process of passing above the planer trunk 16 as shown in FIG. This cutting amount B
Is set to a value larger than the maximum bending amount A of the material 8 to be processed, so that "unevenness" on the lower surface 8b of the material 8 is completely removed and the material 8 is finished smoothly. When the feed slider 18 grasps the workpiece 8 and moves to the downstream side, the front table 14 is further lowered from the position at which the workpiece was stopped and positioned, so that the front slider 14 is moved downward with respect to the workpiece 8 which is transferred horizontally. Friction and interference can be prevented.

Then, as shown in FIG.
The rear end passes above the planer cylinder 16 and the cutting is completed.
When the feed slider 18 reaches a position above the material unloading section 20 adjacent to the downstream end of the slide beam 30, the air cylinders 45 of all the clamp mechanisms 42 are reversely urged, and the first
The clamp body 43 and the second clamp body 44 are separated from each other to release the grip. As a result, the work material 8 is discharged to the material discharge section 20. The work material 8 discharged to the material discharge section 20 is discharged laterally from a cutting line by the planer cylinder 16 by a roller conveyor.

According to the uneven stripping board 10 according to this embodiment, the work material 8 having "unevenness" such as warpage or bending.
Can be cut by the planer cylinder 16 without correcting the vertical unevenness of the material 8 before cutting, The inconvenience that “irregularity” occurs again after cutting can be suitably prevented. In addition, since the control unit in the control box 24 manages the determination of the cutting amount B with respect to the maximum bending amount A for each workpiece 8, cutting conditions (cutting speed) that vary depending on the material of the workpiece 8, the cutting amount B, and the like. By inputting data such as data and feed speed, it is possible to perform optimal cutting. Further, by collecting data on the maximum bending amount A of each material 8 to be processed, various quality controls can be performed.

The uneven board to which the present invention is applied is not limited to the above-described embodiment, but may be suitably implemented in other forms. For example, the unevenness measuring unit 12, the front table 14, and the material unloading unit 20 constituting the planer board may be arranged in series. In the unevenness measuring section 12, fixed detectors 23, 23
In this embodiment, the bending amount is measured while moving the work material 8, but the work material 8 is fixed and the detector 2 is fixed.
The form which moves 3,23 may be sufficient. The cutting amount of the workpiece 8 is set by moving the front table 14 up and down with respect to the planer barrel 16. However, the front table 14 may be fixed and the planer barrel 16 may be moved up and down. is there. Further, it is also possible to configure the clamp mechanism 42 so as to be able to move up and down with respect to the moving body 40, and to set the cutting amount by moving the clamp mechanism 42 up and down.

The number of the clamping mechanisms 42 in the feed slider 18 is not limited to five as in the embodiment, and the number thereof can be changed according to the length of the target material 8 to be processed. Further, as a driving means of the pair of clamp bodies 43 and 44 in the clamp mechanism 42,
The configuration is not limited to the air cylinder 45, and a configuration in which the screw shaft is moved by rotating the screw shaft with a motor can be suitably implemented.

[0034]

As described above, according to the uneven planing machine of the present invention, the work material having "unevenness" such as warpage or bending is gripped and transferred from the width direction. And the "unevenness" of the material before cutting
Can be cut by the rotary cutting means without correcting the inconvenience, and the inconvenience that “unevenness” occurs again after cutting can be suitably prevented. In addition, since the amount of bending of the material to be processed is accurately measured before cutting, and an appropriate amount of cutting is set in accordance with the amount of bending, accurate and reliable `` unevenness '' can be removed, while insufficient cutting and Since excessive cutting or the like is suitably prevented, it is possible to improve work efficiency and reduce production costs.

Further, by forming the pair of clamp bodies in the clamp mechanism so as to be movable close to and away from each other, the workpiece can be gripped without correcting the curvature of the workpiece in the width direction, which is unnecessary for the material. It is possible to perform cutting without applying excessive force.
