As shown in FIG. 1, two wood processing machines 41 are arranged one by one on both sides in the Y direction intersecting the transport path L along the X direction with respect to the case body 42 in a top view. In the present embodiment, the two wood processing machines 41 have the same configuration, and the specific configuration of the wood processing machine 41 will be described below. The two wood processing machines 41 do not necessarily have the same shape, and may be configured to include different shape portions.

The wood processing machine 41 generates rotational power of the blade 44 attached to the mounting portion 51 as a processing head, and also moves the blade 44 in the directions of three orthogonal axes or rotates it in a plurality of directions. It is a device that cuts the processed wood K. As shown in FIG. 2, the wood processing machine 41 includes a mounting portion 51, a rotating mechanism 52, a first moving member 53, a second moving member 54, and a support member 55. The mounting portion 51 can mount a blade 44 capable of processing the processed wood K, and one blade 44 suitable for processing a part manufactured from among the blades 44 having a plurality of types of blades having different shapes is provided. It is selectively attached to the attachment portion 51 and the processed wood K is processed.

The mounting portion 51 is arranged with respect to the ground on which the wood processing machine 41 is installed via two moving members 53, 54 and a rotating mechanism 52, and the movement of the moving members 53, 54 causes three directions (X, Y). , Z direction) is performed, and the rotation mechanism 52 is configured to enable rotation operation in three directions (directions of R1, R2, R3). After the processed wood K is conveyed by the transfer device 30 (upstream transfer device 30a) to a processing position where cutting can be performed by the wood processing-related device 40, the mounting portion 51 performs a moving operation and a rotating operation. The processed wood K is processed by the blade 44 attached to the attachment portion 51.

The mounting portion 51 is provided with a mounting hole into which the blade 44 can be mounted, and the lock mechanism (not shown) is activated after a part of the blade 44 is accommodated in the mounting hole to mount the blade 44. The portion 51 is integrated. Further, an electric motor (not shown) is built in the mounting portion 51, and the output shaft of the electric motor is connected to the blade 44 to transmit rotational power, so that the blade portion of the blade 44 rotates. Various mechanisms can be used as the lock mechanism of the mounting portion 51 and the power transmission mechanism by the electric motor. For example, as the lock mechanism, a configuration by the operation of a lock body that can be moved by hydraulic pressure or pneumatic pressure is used. Alternatively, a mechanism for mounting the blade 44 by using an electromagnetic force may be included.

The rotation mechanism 52 is configured by combining a plurality of parts capable of rotation operation by a motor (not shown), and the rotation mechanism 52 is controlled by the control device S on one end side of the rotation mechanism 52. The direction (posture) of the mounting portion 51 connected to is changed. Specifically, the rotation mechanism 52 is configured to be able to rotate the attachment portion 51 with respect to the first moving member 53 in the directions of R1, R2, and R3 as three orthogonal rotation directions. As the structure of the rotation mechanism 52, various mechanisms such as a support structure using bearings can be used, and the power source of the rotation mechanism 52 is not limited to the motor, but hydraulic pressure or pneumatic pressure. It may be configured by, or two or more kinds of power sources may be combined.

The first moving member 53 is provided with a rotation mechanism 52 on one end side. Further, as shown in FIG. 1, the first moving member 53 is composed of a rod-shaped member that is long and continuous toward the crossing direction side (Y direction side) intersecting the transport path L in the top view, and is directed to the Y direction side. It is provided so that it can move.

Specifically, as shown in FIG. 2, the first moving member 53 is supported by the second moving member 54 via a connecting member 56. Guide rails 61 are provided on both side surfaces of the first moving member 53 on the transport direction side (X direction side) along the transport path L, and are connected to the guide rail 61 via bearings (not shown). 56 is attached. As a result, the first moving member 53 is movably supported in the Y direction with respect to the second moving member 54 by the length of the guide rail 61.

As shown in FIG. 1, the second moving member 54 is composed of a plate-shaped member that is long and continuous in the transport direction side (X direction side) along the transport path L in a top view, and moves in the vertical direction side. It is provided so that it can operate. The support member 55 is provided with a guide rail 62 that is continuous in the vertical direction, and both ends of the second moving member 54 are provided on both ends of the guide rail 62 in the transport direction (X direction) along the transport path L. The parts are connected. As a result, the support member 55 movably supports the second moving member 54 in the vertical direction.

Further, on the upper surface of the second moving member 54, a guide rail 63 that is long and continuous in the transport direction side (X direction side) along the transport path L is provided, and the guide rail 63 is connected to the guide rail 63 via a bearing. 56 is attached. As a result, the first moving member 53 is movably supported in the X direction with respect to the second moving member 54 by the length of the guide rail 63.

The support member 55 is a member that supports the second moving member 54 so as to be movable in the vertical direction. Through the second moving member 54, the support member 55 functions as a member that supports the first moving member 53, the connecting member 56, the rotating mechanism 52, the mounting portion 51, and the cutting tool 44. Here, in the support member 55, the second moving member 54 bends or deforms even when the distance between the second moving member 54 supported by the support member 55 and the cutting tool 44 is large. It is configured to support both sides of the second moving member 54 along the transport path L so as to reduce the number of problems.

Further, the support member 55 includes a pedestal 64 installed on the floor surface, two support pillars 65 provided on the upper side of the pedestal 64, and a connecting piece 66 connecting the upper sides of the two support pillars 65. The connecting piece 66 is a metal part that enhances the rigidity of the two support columns 65, and the two support columns 65 are high because the upper and lower parts of the support column 65 are connected and fixed by the connecting piece 66 and the pedestal 64. It makes it easy to secure rigidity. It is not always necessary to integrate the two support columns 65 constituting the support member 55, the support columns 65 may be provided separately, and only the upper side or the lower side of the support column 65 is connected. It may be configured to do so.

The support pillar 65 is provided with a servomotor 67 for generating a driving force for moving the second moving member 54 in the vertical direction and controlling the vertical position of the second moving member 54, and a ball screw 68. Has been done. The servomotor 67 operates under the control of the control device S, and the power of the servomotor 67 is transmitted to the second moving member 54 through the ball screw 68, so that the second moving member 54 moves up and down. Further, the operation mechanism of the first moving member 53 supported by the second moving member 54 in the X direction and the Y direction is also configured by combining the servomotor and the ball screw.

As the mechanism for moving the two moving members 53 and 54, various mechanisms such as a mechanism using a belt and a mechanism using a ball screw using a servomotor can be used. Further, as the power for moving the two moving members 53, 54, hydraulic pressure or pneumatic pressure may be used, or two or more types of power may be combined.

Here, as shown in FIG. 1, the support pillar 65 has a substantially rectangular cross section that is longer on the Y direction (intersection direction) side in which the first moving member 53 can move than on the X direction side in the top view. It is composed of vertically long metal members formed in a shape. As shown in FIG. 2, the support pillars 65 are provided with guide rails 62 that are continuous in the vertical direction at both ends on the + Y direction side and the −Y direction side along the Y direction side. Further, the second moving member 54 is also formed in a substantially rectangular cross-sectional shape that is longer in the Y direction (intersection direction) side in which the first moving member 53 can move than in the vertical direction (Z direction) side. It is attached to the support member 55 (guide rail 62) at both ends on the + Y direction side and the −Y direction side along the direction side. As a result, even if the first moving member 53 moves significantly toward the + Y direction and the mounting portion 51 and the blade 44 are arranged at positions away from the second moving member 54, the second moving member 54 is rotated in the rotational direction due to the weight. It is easy to secure high rigidity that can avoid the situation of bending, and the sizes of the support member 55 and the second moving member 54 can be made relatively compact.

The control device S is a device that controls the wood precut processing device 10, and is configured by, for example, a personal computer. The control device S includes an input unit for inputting processing data of parts required for a building structure (for example, a drive device capable of reading data from a CD-ROM as a storage medium), an operation unit operated by an operator, and the like. A display device or the like for displaying information on processing (for example, the size of the processed wood K and the processing status) is provided.

Further, the control device S includes driving devices such as a plurality of motors and air cylinders that generate driving force of a large number of moving parts including moving parts such as a feeding device 20, a transporting device 30, and a wood processing machine 41. A large number of sensors for detecting the position are connected (not shown), and the machined wood K is machined by controlling the position and angle of the moving portion by detecting the position of the sensor.

Next, the processing of the processed wood K by the two wood processing machines 41 will be described mainly with reference to FIGS. 3 and 4. FIG. 3 is a view of the wood processing machine 41 viewed from one side surface side (−Y direction side) in the horizontal direction intersecting the transport path L, and FIG. 3A shows the entire wood processing machine 41. 3 (B) and 3 (C) show the peripheral portion of the tool stocker 43 in FIG. 3 (A). Further, FIG. 3A shows a state in which the blade 44 (chainsaw 44a) is arranged in the standby position, and FIG. 3B shows a state in which the chainsaw 44a has advanced into the inside of the case body 42. (C) shows a state in which the chainsaw 44a is attached to the attachment portion 51 and moved to the inside of the processing space. Further, FIG. 4 is a view of the wood processing machine 41 as viewed from the direction side along the transport path L. In addition, in FIGS. 3 and 4, for easy understanding, the arrangement position of the tool stocker 43 for storing the blade 44 is shown by a long-dotted chain line, the blade 44 is shown by a thick solid line, and the holding mechanism 45 is shown by a thin solid line. Illustrated, the processed wood K is illustrated by a chain double-dashed line.

As shown in FIGS. 3 and 4, the two wood processing machines 41 are configured to be capable of simultaneously processing both the upper surface and the lower surface of the processed wood K with respect to the processed wood K. The blade 44 attached to the mounting portion 51 of the wood processing machine 41 is provided so as to be movable in the X, Y, and Z directions with respect to the processed wood K, and the amount of movement of the second moving member 54 in the Z direction and the first movement. The length of the guide rails 61 to 63 (see FIG. 2) so that the amount of movement of the moving member 53 in the Y direction is sufficient for the cross-sectional shape of the maximum processed wood K set as the processing target. The length of each part including the sword is set.

Here, the amount of movement of the first moving member 53 by the second moving member 54 in the X direction is set to a length that allows the processed wood K to be processed in a state where the two blades 44 are lined up in the X direction without contacting each other. Is preferable. As a result, it is possible to facilitate simultaneous processing of the upper surface and the lower surface of the processed wood K by the two wood processing machines 41, or to facilitate processing of either the upper surface or the lower surface of the processed wood K at the same time. The content of processing and the order of processing, such as simultaneous processing of the upper surface and lower surface of the processed wood K and simultaneous processing of two places on either the upper surface or the lower surface of the processed wood K, are the same as those of the processed wood K. It can be set in advance in the control program of the control device S according to the processing content.

As shown in FIG. 4, the processed wood K is provided between the two wood processing machines 41 by the transport device 30 in a state of being laid sideways with the thickness direction facing up and down with respect to the two wood processing machines 41. It is transported to the processing position. When the processed wood K is transported to the processing position, the two wood processing machines 41 perform necessary processing on the processed wood K while the processed wood K remains lying down.

As described above, according to the wood precut processing apparatus 10, since the second moving member 54 is supported by the support member 55 on both ends along the transport path L, the rigidity in which the second moving member 54 is supported is increased. It is easy to make it easy to move the second moving member 54 in the vertical direction while keeping the state of the second moving member 54 close to horizontal and reducing the deflection.

Further, since the first moving member 53 can be arranged at a position close to the vertical direction with respect to the second moving member 54, the mounting portion 51 provided on one end side of the first moving member 53 via the rotation mechanism 52. Even when the (cutting tool 44) is largely separated from the second moving member 54 toward the transport path side, the first moving member 53 is attached to the second moving member 54 due to the weight of the mounting portion 51 and the rotating mechanism 52, the weight of the cutting tool 44, and the like. It is possible to easily reduce the amount of deflection of the arm portion up to the portion where the support is supported. Therefore, it is possible to easily set a large amount of movable amount of the mounting portion 51 from the second moving member 54 to the transport path L side, and it is easy to process even a large cross-sectional shape processed wood K with high accuracy. be able to.

Further, since it is easy to set a large amount of movement of the mounting portion 51 to the transport path L side, the processed wood K having a cross-sectional shape having a large width in the thickness direction is also in a state of being laid sideways with the thickness direction facing up and down. Therefore, it is possible to efficiently perform processing using two wood processing machines 41. For this reason, the entire process can be simplified by eliminating the need for the process of erecting the processed wood K or placing it horizontally, and there is a possibility that the processed wood K may tip over during transportation. It can be reduced and the processed wood K can be easily transported safely.

Here, the wood precut processing apparatus 10 can photograph the processing status of the processed wood K inside the case body 42 (processing space), the delivery status of the cutting tool 44 between the wood processing machine 41 and the tool stocker 43, and the like. It is preferable to provide one or a plurality of camera devices and a display device (for example, a liquid crystal display) for displaying an image (moving image) taken by the camera device. This makes it possible to check the situation in the machining space from another place such as the installation place of the control device S. Therefore, even if two wood processing machines 41 are provided on both sides of the transport path L or the equipment is enlarged so as to be able to process a large processed wood K, a camera device is likely to have a blind spot. It is possible to safely process the processed wood K by using the photographed image of the above, and it is possible to easily detect the occurrence of a problem. It is preferable that one or more camera devices are installed in a portion between the two wood processing machines 41, and the camera devices are oriented toward the side of the two wood processing machines 41 at a position higher than the transport path L (opposite direction side). It is preferable to install it in two or more places (so that it faces). Further, one or more camera devices may be provided with an operation mechanism capable of moving the shooting position in the vertical direction or rotating so as to make the shooting direction different. Further, the configuration of the camera device and the display device is not limited to the above, and for example, the camera device does not need to be provided only inside the case body 42, and instead of or in addition to this, the transport device 30 or the like. Another place such as the tool stocker 43 may be installed so that the photographed image can be taken, or display devices for displaying the photographed image may be installed at a plurality of places.

Next, the transfer device 30 will be described mainly with reference to FIGS. 1 and 5. 5 is a diagram for explaining the upper transport portion 32 of the transport device 30, and FIG. 5 (A) is a perspective view showing a part of the upper transport portion 32, FIGS. 5 (B) and 5 (FIG. 5). C) is a diagram showing a state in which processed wood K having a different cross-sectional shape is sandwiched between two clamps 73. In FIG. 5A, the center position of the transport path L is shown by a thin alternate long and short dash line. Further, in FIGS. 5 (B) and 5 (C), the outer shapes of the clamp operating portion 74, the slide moving portion 75, and the lower transport portion 31 are shown by a alternate long and short dash line.

The wood precut processing device 10 has a function (measurement function) for measuring the external dimensions of the processed wood K and a clamp function capable of positioning, fixing, and transporting the processed wood K having a different cross-sectional shape by sandwiching the processed wood K with different forces. And have. This measurement function and the clamp function are realized by controlling the transfer device 30 with the control device S.

As shown in FIG. 1, the transport device 30 is configured by combining a lower transport unit 31 and an upper transport unit 32. The lower transport unit 31 is a portion that supports the lower side of the processed wood K so that the processed wood K can be moved along the transport path L. Specifically, a large number of rollers 72 sandwiched between the two rails 71 are provided in the lower transport unit 31 at a height position away from the floor surface, and the rollers 72 are controlled by the control device S. The processed wood K moves along the transport path L by being rotated by a power source (for example, a motor).

As shown in FIG. 5, the upper transport unit 32 has two clamps 73 for sandwiching the processed wood K from both sides in the horizontal direction (Y direction) and two clamps 73 on the crossing direction side intersecting the transport path L. It is configured by combining a clamp operating portion 74 to be operated, a clamp operating portion 74 movable in the direction along the transport path L, and a slide moving portion 75.

As shown in FIG. 5B, the two clamps 73 are provided so as to be located on both sides in the horizontal direction with respect to the processed wood K whose lower side is supported by the lower transport portion 31 (roller 72). Has been done. The two clamps 73 are provided so as to be located on both sides (see the two-dot chain line in FIG. 5B) along the horizontal direction intersecting the transport path L with respect to the transport path L.

As shown in FIG. 5A, the clamp motor 76 provided in the clamp operating portion 74 is connected to the two clamps 73 via an operating mechanism (thick alternate long and short dash line in FIG. 5A). The two clamps 73 are arranged so as to be separated from each other on both sides in the horizontal direction by an equal distance with respect to the center of the transport path L, and by the operation of the clamp motor 76, the side in the direction approaching the center of the transport path L. And, it is configured to be movable in the direction away from it. The operating mechanism for connecting the two clamps 73 and the clamp motor 76 includes, for example, a gear mechanism 77 having a built-in gear for transmitting the power of the output shaft of the clamp motor 76, and a ball screw 78 connected to the gear mechanism 77. Consists of.

FIG. 5A shows a force transmission path from the output shaft of the clamp motor 76 via the ball screw 78 by a thick alternate long and short dash line. By controlling the clamp motor 76 by the control device S, the two clamps 73 move linearly. The moving direction of the clamp 73 does not necessarily have to be a linear moving direction, and may be another moving direction such as a curved moving direction.

As shown in FIG. 5A, the two clamps 73 are formed in a plate shape having the moving direction (Y direction) of the clamp 73 as the thickness direction. Further, the two clamps 73 have a portion (main body portion) in which the ball screw 78 is connected to the upper end portion and is formed long in the vertical direction, and one side (FIG. 5 (A)) which is shorter in the vertical direction than the main body portion. It has a shape having a protruding portion (protruding portion) in the + X direction side of the above. The projecting portion is provided so as to project from the main body portion to the side where the wood processing machine 41 and the case body 42 (processing space) are located on one side along the transport path L. As shown in FIG. 1, the upper transport unit 32 is arranged on the upstream side (-X direction side) and the downstream side (+ X direction side) with respect to the case body 42 (wood processing machine 41) forming the processing space. As for the upper transport portion 32 on the upstream side, as shown in FIG. 5A, a protruding portion is located on the downstream side (+ X direction side) of the transport path L with respect to the main body portion, and vice versa. The upper transport portion 32 on the downstream side is configured such that the protruding portion is located on the upstream side (-X direction side) of the transport path L with respect to the main body portion (not shown). By providing this protrusion, the operating mechanism of the clamp 73 can be arranged away from the case body 42, and the processed wood K can be sandwiched by the clamp 73 near the case body 42. The short length of processed wood K can also be processed by the wood precut processing apparatus 10.

As shown in FIG. 5B, the two clamps 73 have side surfaces on both ends along the horizontal direction intersecting the transport path L with respect to the processed wood K whose lower side is supported by the lower transport portion 31. It moves between a separated position away from (the position of the alternate long and short dash line in FIG. 5B) and a contact position in contact with the processed wood K. At the contact position where the two clamps 73 are in contact with a part of the processed wood K, the driving force is increased until the driving force for the two clamps 73 to move in the approaching direction reaches a predetermined target value. It is controlled by the control device S. As a result, a part of the processed wood K is sandwiched between the two clamps 73 (clamped state), and the movement of the processed wood K is restricted. Due to the restriction of the movement of the processed wood K by the two clamps 73, the positioning and fixing when the processed wood K is cut are performed, and the two clamps 73 are moved in the longitudinal direction of the processed wood K by the slide moving portion 75. By moving, the processed wood K is transported (moved).

When the processed wood K is loaded from the loading device 20 to the transporting device 30, there are two on the traveling direction side (+ X direction side in FIG. 1) of the transport path L from the position where the processed wood K is loaded into the loading device 20. The control device S controls each portion so that the clamp operating portion 74 provided with the clamp 73 is located. After the processed wood K is put into the transport path L, when the processed wood K is advanced by the lower transport portion 31 to the portion where the clamp operating portion 74 is located, the processed wood K moves between the two clamps 73. The movement of the processed wood K can be restricted by the two clamps 73.

Here, when the processed wood K is charged from the charging device 20 to the transporting device 30, the processed wood K is loaded so that the longitudinal direction of the processed wood K coincides with the direction along the transport path L of the processed wood K. Further, when the cross-sectional shape of the processed wood K (the cross section of the processed wood K intersecting in the longitudinal direction) is rectangular, the direction in which the length of one side is short (thickness direction) becomes the vertical direction after loading, and the length of one side. The processed wood K is basically put in a state in which the long direction (width direction) becomes the horizontal direction (sideways) after being put in. As a result, the processed wood K can be safely put into the transport device 30 in a stable state due to the weight of the processed wood K, and the processed wood K can be overturned even during the transport by the transport device 30. Can be prevented.

Further, even a large-sized processed wood K can be processed in a state of being laid on its side with the thickness direction facing up and down, so that the wood precut processing apparatus 10 can process the large-sized processed wood K. , The length in the vertical direction required for processing can be shortened. For this reason, it is possible to eliminate the need for a factory having a high ceiling or drilling holes in the floor surface, and it is possible to easily avoid a situation in which problems occur in the size of the factory or the arrangement of the wood processing machine 41.

Even if the cross-sectional shape of the processed wood K is not a rectangle but an elliptical shape or a polygon different from a quadrangle, it is preferable to transport the processed wood K in the most stable state by its own weight, and the thickness direction is the vertical direction. It is preferable to lay it sideways with the width direction, which is longer than the thickness direction, as the horizontal direction. Further, it is not always necessary to put all the processed wood K into the transport device 30 so that the vertical direction is the thickness direction, and the width is wide even when the cross-sectional shape is substantially square, rectangular or polygonal. If it can be determined that the processed wood K is unlikely to tip over during transportation or cutting, such as when the length ratio of the thickness is close to 1 (for example, when it is 0.8 or more), the thickness direction is horizontal. There may be exceptional cases of transport in the direction. However, in the following description, a basic case will be described in which the processed wood K is transported and cut in a state of being laid down with the thickness direction of the cross section in the vertical direction.

The clamp motor 76 constitutes a driving means for generating an operating force in which the two clamps 73 move from the separated position to the one side and the opposite side approaching the contact position, and is composed of a servomotor capable of feedback control. ing. The operating force of the clamp motor 76 is controlled by the control device S.

The clamp motor 76 is configured by combining an electric motor that generates power, a detector (sensor) that detects the state of the electric motor, and a servo amplifier. The servo amplifier is a control unit that controls the electric motor in response to a command (target value) from the control device S, and the electric motor is matched with a command from the control device S in response to information input from the detector. Performs feedback control to control the power supply of.

The detector of the clamp motor 76 detects the position information corresponding to the arrangement positions of the two clamps 73, and the position information is output to the control device S. The control device S detects the arrangement position of the two clamps 73 based on the position information output from the detector, thereby measuring the dimension of the processed wood K in the width direction.

The control device S controls the clamp motor 76 by issuing a command to the servo amplifier of the clamp motor 76 to move the two clamps 73 in a certain direction until the value as the target value is reached. In the clamp motor 76, the operation of the electric motor is controlled through the servo amplifier by the control (command) of the control device S, and the electric power is controlled so that the electric motor rotates until the position or contact force corresponding to the target value is reached. To. As a result, the arrangement position of the clamp 73 connected to the clamp motor 76 can be moved to the position set as the target value, or the two clamps 73 come into contact with the processed wood K and the contact force (hereinafter referred to as “the processed wood K” is pinched). , Also called clamping force) can be increased until the clamp force set as the target value is reached.

Here, the movement control of the clamp 73 and the control of the clamp force are executed by combining the servo amplifier and the control device S. This makes it possible to move the two clamps 73 at high speed while simplifying the control of the control device S. Further, in the present embodiment, a general-purpose servo motor is used as the clamp motor 76. As a result, it is possible to measure even the width dimension of the processed wood K having a large cross-sectional shape in a short time with a cheaper configuration than preparing a dedicated motor. As the power source of the clamp motor 76, the moving mechanism 46 of the clamp 73 may be configured by using a hydraulic or pneumatic power source instead of the motor. Further, the clamp motor 76 may be configured by separately combining a motor and a detector such as an encoder, not limited to the servo motor.

In the control device S, two or more kinds of different sizes of clamping forces are set as the clamping forces. Specifically, the size (weight), shape, material, etc. of the processed wood K are controlled so that the processed wood K is clamped by two or more different clamping forces according to the type and application of the processed wood K. The device S controls the clamp motor 76.

For example, control is performed so that the clamping force differs depending on the size (weight) of the processed wood K. A high value clamping force is set as a target value for a heavy processed wood K, and a lower clamping force is set for a light one. As a result, it is possible to easily avoid a situation in which a high contact force acts on the surface of the processed wood K and the surface portion of the clamp 73 and the processed wood K in contact with the clamp 73 is deformed or damaged.

Further, the clamping force is controlled to be different depending on the cross-sectional shape of the processed wood K. Compared to the case where the area on both ends in the width direction is large (when the vertical length on both ends is long) as shown in FIG. 5 (B), the tip portions on both ends as shown in FIG. 5 (C) are In the case of a sharp shape, control is performed so that the clamping force is set to a low value. This makes it possible to prevent the tip portion having a sharp shape from being deformed.

The control of the clamping force may be changed so as to have a high value until the middle of processing of one processed wood K and then to a low value. For example, when processing is performed so that the shape changes from the cross-sectional shape as shown in FIG. 5 (B) to the cross-sectional shape as shown in FIG. 5 (C), it is large before the cross-sectional shape changes. Processing wood K is clamped with a clamping force to enable high-speed cutting, and after the cross-sectional shape changes, the clamping force is reduced so that the clamping force required for cutting can be reduced. In addition, the control of the control device S may be executed.

Further, the clamping force may be changed so as to have a lower value during transportation of the processed wood K as compared with before cutting or during cutting. The clamping force required for transportation may be lower than the clamping force required for cutting, and the processed wood K is divided or cut by the cutting process, so that the processed wood K is processed. Will be lightweight. Therefore, after the shape has changed to the cross-sectional shape as shown in FIG. 5C, the portion where the shape has changed can be clamped and conveyed with a low clamping force. That is, by changing the clamping force so that it becomes a low value during transportation, the processed wood K (or the processed part) is conveyed without deformation or breakage while increasing the degree of freedom of the part to be clamped. be able to.

Further, when the processed wood K is clamped by the clamp 73, the clamping force may be changed depending on the length of the section where the clamp 73 and the processed wood K are in contact with each other in the X direction along the transport path L. For example, when processing a short processed wood K, it is necessary to clamp the processed wood K only by a protruding portion having a short vertical length of the clamp 73. In this case, compared with the case of clamping including the main body portion. Therefore, it is preferable to control the clamping force to be low. When the processed wood K is clamped only by the protruding portion, the part where the clamping force acts on the clamp 73 by the ball screw 78 and the position where the clamp 73 contacts the processed wood K are greatly separated from each other, so that the clamp 73 is easily deformed. The contact of the small protrusions may cause a dent on a part of the surface of the processed wood K. Therefore, when the processed wood K is clamped only by the protruding portion of the clamp 73, it is preferable to change the clamping force so as to have a lower value than when the main body portion is used.

In addition to the above, when the clamping force is set low, the processing of the processed wood K having a soft surface and the surface of the processed wood K can be visually recognized as a part of the appearance after the construction of the building structure. The case is exemplified.

The control of the clamping force is performed by the control device S instructing a target value to the servomotors constituting the clamp motor 76. Therefore, the feedback control is applied to the servomotor as compared with the case where the control device S executes all the controls so that the contact force between the processed wood K and the clamp 73 and the arrangement position of the clamp 73 reach the target value. It can be done, and the control of the control device S can be simplified.

The position information corresponding to the contact position of the processed wood K when the movement of the clamp 73 is stopped is detected by the detector of the clamp motor 76 and used for the control of the control device S. For example, the control device S instructs the operator to stop the processing of the processed wood K and input another processed wood K when the width dimension is out of the allowable dimension range. Control to do. In addition, if the width dimension is short, such as the shortest length within the allowable dimension range, the depth of the hole for attaching the hardware used for joining with other members may be insufficient. Therefore, the control to set the depth of the hole is executed because the width dimension is short.

Here, when the processed wood K is charged from the charging device 20 to the transport device 30, as shown in FIG. 1, the center of the processed wood K in the width direction is located at the center of the transport path L in the top view. It is preferable to put the processed wood K into the transport device 30. For example, when the processed wood K is charged from the charging device 20 to the transport device 30, a stopper member (not shown) is applied to the processed wood K at the timing when the center of the processed wood K in the width direction is located at the center of the transport path L. A stopper member may be provided so that the wood K comes into contact with the wood K. May be provided with a mechanism for moving at high speed. As a result, when measuring the external dimensions of the processed wood K in the width direction by moving the clamp 73 of the transport device 30, the two clamps 73 can easily come into contact with the processed wood K at the same time, and the width of the processed wood K can be easily contacted. It is possible to easily detect the external dimensions in the direction in a short time.

As a measurement function in the wood precut processing apparatus 10, it is possible to measure external dimensions other than the width direction of the processed wood K. For example, the length dimension of the processed wood K is executed by moving the two clamps 73 by the slide moving portion 75 of the upper transport portion 32 after the processed wood K is loaded from the feeding device 20 to the transporting device 30. can do. For example, as shown in FIG. 5A, the two clamps 73 are provided with a clamp sensor 79 that can detect the presence or absence of the processed wood K in the portion between the two clamps 73.

The clamp sensor 79 is composed of, for example, a multi-axis photoelectric sensor (area sensor) configured by arranging a plurality of non-contact photoelectric sensors in the vertical direction, and the clamp sensor 79 is connected to the control device S. The control device S controls the slide moving portion 75 of the upper transport portion 32 to move the two clamps 73 in a section exceeding the total length of the processed wood K, and the processed wood by the clamp sensor 79 along the longitudinal direction of the processed wood K. By detecting the presence / absence of K, the length dimension of the processed wood K is detected. The slide moving unit 75 may operate the clamp operating unit 74 along the transport path L, and may, for example, form an operating mechanism by combining a servomotor, a rack, and a pinion.

As described above, according to the wood precut processing device 10, the size (external dimensions) of the processed wood K is measured by the detector or the like of the clamp motor 76, and the control device S determines the measurement result of the external dimensions of the processed wood K. Based on this, it is determined whether or not the necessary parts can be manufactured, and if the necessary parts can be manufactured, processing is performed, and if the necessary parts cannot be manufactured, control is executed to prompt the operator to change the processed wood K. As a result, it is possible to avoid a situation in which processing is started using the processed wood K, which cannot manufacture necessary parts due to dimensional defects or deformation of the processed wood K.

Further, the control device S determines the size of the processed wood K by a detector or the like of the clamp motor 76, and when the processed wood K is different from the standard design dimension (median value), the processing size (amount). Performs control to change. This makes it possible to reliably attach other parts to be attached to the processed wood K, and it is easy to secure the required strength, and at the same time, it is easy to set a large allowable range for the processed wood K that can process the structural material. can do. Therefore, the processed wood K can be easily obtained at a low price, the number of defective processed wood K can be reduced, and it is possible to avoid a situation in which the manufacturing period of parts is prolonged due to the mixing of defective products. can.

Further, by the control of the control device S, it is possible to set two or more different sizes of clamp forces as the clamp force of the clamp 73, and the size (weight), shape, material, etc. of the processed wood K can be set. The processed wood K is clamped with two or more different clamping forces depending on the type and application of the wood. Therefore, the clamping force required for transportation and positioning can be changed according to the type of the processed wood K, and it is easy to avoid the situation where the surface portion of the processed wood K is deformed or damaged. Can be done.

Further, when processing a plurality of types of processed wood K, it is used for transporting the processed wood K in confirming the correctness of the processed wood K as a material, determining the processing content, and controlling the force required for transport and positioning. The configuration of the clamp 73 of the upper transport portion 32 is used. Therefore, it is necessary to reduce the cost required to support a plurality of types of processed wood K, reduce the material cost required for the processed wood K, and facilitate the manufacture of parts in a good-looking state. Can be done.

The measurement function of the wood precut processing apparatus 10 is not limited to the width direction and the length direction of the processed wood K, and other external dimensions may be measured. For example, a clamp or a detector capable of contacting the upper surface of the processed wood K from above with respect to the processed wood K whose lower side is supported by the lower transport portion 31 is operated by a servomotor, or with respect to the processed wood K. Two clamps may be operated by a servomotor from two vertical directions so that the external dimensions of the processed wood K in the vertical direction can be measured.

Further, when a clamp is provided that contacts the upper surface of the processed wood K from above and generates a force required for positioning the processed wood K in the vertical direction (thickness direction), feedback control is used as a power source for the clamp. A possible servomotor may be used, but it is preferable to use a geared motor that does not have feedback control, or a cylinder that operates by hydraulic pressure or pneumatic pressure. As a result, while limiting the equipment that uses the servo motor and suppressing the cost increase, measurement and positioning of the processed wood K when it is possible to process a large processed wood K in a sideways state can be executed at high speed and with high accuracy. It can be possible. Further, as a suitable example in which a servomotor and a non-servomotor are combined as the power source of the clamp, the cross-sectional size in which the processed wood K is allowed to be processed is up to 120 cm in the width direction and 60 cm in the thickness direction. The case of up to is exemplified. As described above, when the allowable cross-sectional size is shorter in the thickness direction than in the width direction, and particularly when the thickness direction is significantly different such as about half or less in the width direction, the power source of the clamp in the thickness direction is used. It is preferable to use a power source other than the servo motor.

Next, as a configuration relating to the tool stocker 43, a holding mechanism 45 for holding the cutting tool 44 removed from the mounting portion 51 of the wood processing machine 41 will be described mainly with reference to FIG. FIG. 6A is a diagram showing a state in which the blade 44 is held by the holding mechanism 45, and FIG. 6B is a diagram showing a state in which the blade 44 is removed from the holding mechanism 45. In addition, in FIGS. 6A and 6B, the front view of the holding mechanism 45 seen from the side of the gap forming portion 94 and the view seen from the lower side are shown side by side.

As shown in FIG. 3 and the like, the wood precut processing apparatus 10 has a plurality of holding mechanisms 45 as blade holding means for holding a plurality of blades 44 capable of cutting the processed wood K in a predetermined standby position. It is provided. As shown in FIG. 6A, each blade 44 is for holding the blade portion 81 for cutting (the rod shaft-shaped drill is exemplified in FIG. 6) and the blade 44 in the holding mechanism 45. A held portion 82 formed in the above and a spindle portion 83 for transmitting the rotational force of the cutting motor to the blade portion 81 by engaging with the mounting portion 51 of the wood processing machine 41 are provided.

Each blade 44 is held by the holding mechanism 45 by the moving operation of the mounting portion 51 by the wood processing machine 41. Further, after the blade 44 required for cutting is attached to the attachment portion 51 of the wood processing machine 41, as shown in FIG. 6B, the attachment portion 51 is moved (in FIG. 6B). The blade 44 is removed from the holding mechanism 45 by (movement in the + S direction).

As shown in FIG. 6, the holding mechanism 45 includes two blade holding members 84, a limiting member 85, a coil spring 86, and a base body 87. The base body 87 has two first rotating shafts 88 that rotatably support the two blade holding members 84, a second rotating shaft 89 that rotatably supports the limiting member 85, and a blade holding member 84. It has a stopper portion 91 that limits the rotation range of the above, and is composed of a metal part in which these are integrated.

The two blade holding members 84 have a symmetrical shape centered on the blade 44, and are configured to be uniformly movable on both sides with respect to the blade 44 with the first rotation shaft 88 as the center (central axis). The blade holding member 84 is rotated to hold the blade 44 in a holding posture (first posture) as shown in FIG. 6 (A), and to attach and attach the blade 44 as shown in FIG. 6 (B). It is provided so as to be displaceable between the removable posture (second posture). It is not necessary to enable both of the two blade holding members 84, and one blade holding member 84 may be inoperable and only the other blade holding member 84 may be operable.

As shown in FIG. 6A, the blade holding member 84 has a first direction side (+ S direction side in FIG. 6) which is one side with respect to the first rotation shaft 88 which is the center of the rotation operation. A blade holding portion 92 formed in an arcuate shape that comes into contact with the outer peripheral portion (held portion 82) of the blade 44 and enables the blade 44 to be held in the standby position is provided. The blade holding portion 92 is provided in an arc shape on each of the two blade holding members 84, and the outer peripheral portion of the blade 44 comes into contact with the portion between the two blade holding portions 92 so that the blade 44 can be held in the standby position. It is composed.

The shape of the blade holding portion 92 may be any shape as long as it can be in contact with the outer peripheral portion of the blade 44 to hold the blade 44 in a stable state, and may be not limited to an arc shape but may be another shape such as a polygonal shape. good. Further, the blade holding portions 92 of the two blade holding members 84 do not necessarily have to have a symmetrical shape, and may have a shape different from the symmetrical shape such that the length of the arcuate portion on one side is formed short.

The blade holding portion 92 has a shape having a ridge portion 93 so that the central portion in the vertical direction has a slightly smaller inner diameter, and the ridge portion 93 is formed on the outer peripheral portion of the blade 44 (held portion 82). It is configured to be able to enter the groove-shaped support portion 82a to be formed. By inserting the ridge portion 93 into the support portion 82a, the vertical movement of the blade 44 is restricted when the blade 44 is sandwiched between the blade holding portions 92.

On the side far away from the blade holding portion 92 with respect to the first rotating shaft 88 on the first direction side (+ S direction side in FIG. 6), the blade holding portion 92 to the blade 44 when arranged in the release posture. A gap forming portion 94 is provided in which a gap having a size capable of allowing the gap to escape from is formed. When the gap forming portion 94 is arranged in the holding posture, the gap width of the gap forming portion 94 is smaller than that in the case where the gap forming portion 94 is arranged in the releasing posture, so that the outer peripheral portion of the cutting tool 44 is sandwiched between the cutting edge holding portions 92. The blade 44 is held by the blade holding member 84.

The coil spring 86 is attached to the two blade holding members 84 so as to generate a rotational force to one side that is in a holding posture with respect to the two blade holding members 84. Specifically, the coil spring 86 is on the side opposite to the first direction side where the blade holding portion 92 is provided (second direction side, −S direction side in FIG. 6) with respect to the first rotation shaft 88. It is arranged in a compressed state so that the two blade holding portions 92 generate an urging force on the approaching direction side. As a result, the blade holding member 84 is configured so that the urging force of the coil spring 86 always acts on the side in the direction of narrowing the gap width of the gap forming portion 94, and the blade 44 can be maintained in a state of being held by the blade holding portion 92. Will be done. It is not always necessary to change the posture of the blade holding member 84 by the coil spring 86, and the posture of the blade holding member 84 may be changed by using a driving force such as a motor, hydraulic pressure, or pneumatic pressure. When the driving force is used for the posture change, the driving force may be controlled by the control device S.

When the blade 44 supported by the blade holding portion 92 is moved to the side of the gap forming portion 94 (when the blade 44 is moved to the + S direction side in FIG. 6), the outer peripheral portion of the blade 44 is the gap forming portion. The blade holding member 84 is rotated to the direction side (R direction side in FIG. 6A) to widen the gap of 94. In a situation where the rotation operation is not restricted by the limiting member 85, the gap of the gap forming portion 94 expands while the coil spring 86 is gradually compressed. When the blade holding member 84 rotates to the release posture shown in FIG. 6B, the blade 44 is in a state where it can be pulled out from the blade holding portion 92. The spindle portion 83 of the blade 44 functions as a connecting portion to which the mounting portion 51 of the wood processing machine 41 is connected, and the mounting portion 51 of the wood processing machine 41 is connected to the spindle portion 83 of the blade 44, and the wood processing machine 41 is connected. The power is transmitted to the blade 44 by the power of the blade 44, and the blade 44 is removed from the blade holding portion 92. The direction in which the blade 44 is removed does not necessarily have to be the direction side (the + S direction side in FIG. 6A) where the gap forming portion 94 is provided with respect to the blade holding portion 92, and the blade 44 moves to another direction side. You may try to do it. For example, the blade 44 may be moved to the direction in which the mounting portion 51 is located with respect to the blade 44, and the blade 44 may be removed from the blade holding portion 92.

When the blade 44 is held by the blade holding member 84, first, the blade 44 is moved so that the height positions of the ridge portion 93 of the blade holding portion 92 and the support portion 82a of the outer peripheral portion of the blade 44 are matched. do. After that, the blade 44 is brought closer to the gap forming portion 94 from the side away from the first rotation shaft 88 from the gap forming portion 94 (the blade 44 is moved toward the −S direction side in FIG. 6).

After that, when the outer peripheral portion of the blade 44 comes into contact with the gap forming portion 94 and the blade 44 is further moved (advanced), the coil spring 86 is gradually compressed and the gap of the gap forming portion 94 gradually expands, and the blade 44 becomes the blade. It gradually enters the holding portion 92. Further, when the blade 44 is moved, the blade 44 is completely inserted between the blade holding portions 92, and the outer peripheral portion of the blade 44 is sandwiched by the blade holding portion 92 by the urging force of the coil spring 86, so that the blade 44 is moved. It is in a state of being held (supported) by the blade holding portion 92.

The gap forming portion 94 is formed so that the side farther away from the blade holding portion 92 has a larger gap width in the bottom view, and the blade 44 is easily inserted into the space between the gap forming portions 94. Further, a stopper portion 91 is provided between the two blade holding members 84, and when the blade holding member 84 comes into contact with the stopper portion 91, the blade holding member 84 moves toward the side in which the blade holding portion 92 is narrowed. The rotation range is limited. By providing the stopper portion 91, the blade holding member 84 is maintained in the holding posture even when the cutting tool 44 is not held by the holding mechanism 45.

The limiting member 85 is a member that can limit the operation of the blade holding member 84 by a rotating motion. The limiting member 85 rotates around the second rotating shaft 89 (central axis) to limit the rotating operation of the blade holding member 84 to the holding posture, and from the holding posture to the releasing posture. The release state in which the blade holding member 84 can be rotated is configured to be switchable. The limiting member 85 is rotatably provided by a second rotating shaft 89, and the second rotating shaft 89 is connected to a driving means (for example, an air cylinder or a motor). The drive means is driven and controlled by the control device S, and the posture of the limiting member 85 is switched between the restricted state and the released state.

The limiting member 85 extends from the rotation center of the limiting member 85 corresponding to the center position of the second rotating shaft 89 to the outer peripheral portion in contact with the blade holding member 84 in the axial direction (bottom view) of the second rotating shaft 89. The distances are formed in different shapes. Specifically, in the axial view of the second rotation shaft 89, the limiting member 85 is a constant distance from the rotation center of the second rotation shaft 89 by a plane parallel to the outer shape having a substantially circular cross section. The contact portion 95, which has a shape as if the separated end portions are cut off and has an arcuate outer shape separated from the center position of the second rotation shaft 89 by a certain distance, and the second contact portion 95 than the contact portion 95. The shape has a release portion 96 close to the center position of the rotation shaft 89.

Further, the limiting member 85 rotates about 90 degrees around the second rotating shaft 89, so that a portion facing the two blade holding members 84 (hereinafter, also referred to as a lock portion 97) is a contact portion. The restricted posture of 95 and the released posture in which the portion in contact with the two blade holding members 84 becomes the release portion 96 are switched.

In the state where the limiting member 85 is in the limiting posture, the contact portion 95 is arranged at a position facing the R direction side which operates when the gap width of the gap forming portion 94 is widened with respect to the blade holding member 84. Further, even if the blade holding member 84 tries to rotate so as to take the releasing posture from the holding posture, the length from the center of the second rotating shaft 89 to the contact portion 95 is a lock portion to the extent that the releasing posture can be taken. It is set so that there is no gap with 97. As a result, the cutting tool holding member 84 can be brought into a locked state in which the cutting tool holding member 84 is maintained in the holding posture by the limiting member 85 in the limiting posture.

In this way, the limiting member 85 rotates to change the distance between a part of the blade holding member 84 (lock portion 97) and the contact portion 95, and the rotating operation of the blade holding member 84 is maintained. The limiting state limited to the posture and the releasing state in which the blade holding member 84 can rotate to the releasing posture are configured to be switchable by the limiting member 85. Therefore, the blade 44 can be switched between the locked state in which the blade 44 cannot be removed by the blade holding member 84 and the unlocked state in which the locked state is released only by a constant rotational operation of the limiting member 85. The 44 can be reliably held by the holding mechanism 45.

Further, with respect to the first rotation shaft 88 that makes the blade holding member 84 rotatable, a blade holding portion 92 and a gap forming portion 94 are provided on one side (+ S direction side), and the opposite side (-S direction). A limiting member 85 is provided on the side). Therefore, the limiting member 85 is arranged at a position away from the blade holding portion 92 and the gap forming portion 94, and when the cutting tool 44 is attached to or removed from the attaching portion 51 of the wood processing machine 41. It is possible to easily avoid a situation in which the limiting member 85 or the mechanism for driving the limiting member 85 becomes an obstacle. Further, the limiting member 85 may be arranged on the same direction side as the side where the cutting tool 44 is located (that is, the portion between the two cutting tool holding members 84) with respect to the two cutting tool holding members 84, and the limiting member may be arranged. Even if 85 is added, the size of the holding mechanism 45 including the blade holding member 84 can be made small and easy to configure.

Further, the limiting member 85 is arranged so that the coil spring 86 is located between the first rotating shaft 88 that makes the blade holding member 84 rotatable. Therefore, the position where the limiting member 85 and the blade holding member 84 come into contact with each other and the distance between the first rotating shaft 88 are set wide to facilitate damage to the locking mechanism by the limiting member 85, and between them. A coil spring 86 can be arranged in the space of the portion to reduce the size of the holding mechanism 45.

Here, the limiting member 85 does not necessarily have to be provided in all the holding mechanisms 45. If the cutting tool 44 can be reliably held in the standby position in the holding posture by the coil spring 86, the limiting member 85 and the drive mechanism portion for operating the limiting member 85 may be omitted. As a preferable example by providing the limiting member 85, for example, there is a case where the cutting tool 44 held in the standby position is configured to be attached to the attachment portion 51 of the wood processing machine 41 after being moved. .. A blade 44 such as a chainsaw 44a or a disk-shaped saw that is cut using a chain tends to be larger and heavier than a blade 44 such as a rod-shaped drill or a router bit. For this reason, for some of the blades 44, a holding mechanism 45 that can move the blades 44 and is provided with a limiting member 85 is adopted, whereby the blades 44 are moved by the momentum of the movement of the blades holding member 84. It is possible to easily avoid a situation in which the blade holding member 84 is detached from the blade holding member 84.

Further, if the mounting portion 51 of the wood processing machine 41 can be moved to the standby position of the large blade 44, the range in which the wood processing machine 41 can perform cutting may be narrowed. Therefore, in the present embodiment, the chainsaw 44a, the cutter 44b which is formed into a columnar shape thicker than the drill and can efficiently form a planar shape, and the large saw (not shown) have the blade 44 from the standby position. A moving mechanism 46 that enables movement is provided (see FIG. 3).

The limiting member 85 may be movable so as to continue to rotate in a certain direction, or operates within a rotation operating range of approximately 90 degrees, and shifts to a restricted state and a released state. The direction of rotation may be reversed from time to time. Further, the outer shape of the limiting member 85 is not limited to the above, as long as the restricted state and the released state can be switched by the movement of the contact portion 95 due to the rotational operation of the limiting member 85, and the shape is different from the above-mentioned shape. It may be configured by.

Hereinafter, the moving mechanism 46 that enables the holding mechanism 45 to move can be described with reference to FIG. 3 mainly. Since the moving mechanism 46 is provided for the chainsaw 44a and the cutter 44b and has the same configuration, the moving mechanism 46 of the chainsaw 44a will be described as an example.

The moving mechanism 46 is a mechanism that enables the blade holding member 84 and the limiting member 85 to move between the standby position and the advance position advanced into the machining space with respect to the standby position in an integrated state. Is. The moving mechanism 46 includes an operating shaft 101 capable of linear operation and a drive motor 102 for operating the operating shaft 101. The drive motor 102 is fixed to the case body 42 of the wood processing-related device 40 (not shown), and the operating shaft 101 is connected to the base body 87 constituting the main body portion of the holding mechanism 45.

The operating range of the operating shaft 101 includes an advancing position corresponding to the advancing state in which the blade holding member 84 (chainsaw 44a) has advanced into the processing space inside the case body 42 due to a straight-ahead operation, and the outside of the case body 42. Therefore, the blade holding member 84 (chainsaw 44a) is set so as to be movable from the standby position corresponding to the standby state in which the blade holding member 84 (chainsaw 44a) is retracted to the outside of the machining space. As a result, the moving mechanism 46 allows the blade holding member 84 and the limiting member 85 to move between the standby position and the advance position advanced into the machining space with respect to the standby position in an integrated state. Can be.

The control device S stores a control program for controlling the moving operation of the blade holding member 84 by the moving mechanism 46, the rotating operation of the limiting member 85, and the position and orientation of the mounting portion 51 of the wood processing machine 41.

The operation control of the moving mechanism 46, the limiting member 85, and the wood processing machine 41 by the control program is performed as follows. First, under the control of the control device S, the limiting member 85 and the cutting tool holding member 84 are moved from the standby position (see FIG. 3A) to the advancing position (see FIG. 3B) when the limiting member 85 is in the restricted state. ).

After moving to the advanced position, the operation of the wood processing machine 41 is controlled so that the chainsaw 44a held by the blade holding member 84 is attached to the attachment portion 51 of the wood processing machine 41. By the operation of the wood processing machine 41, the mounting portion 51 engages with the spindle portion 83 of the chainsaw 44a, and the chainsaw 44a is mounted on the mounting portion 51 and integrated by the operation of the lock mechanism.

After the chainsaw 44a is attached to the attachment portion 51 of the wood processing machine 41, the limiting member 85 is rotated so as to switch the limiting member 85 to the released state (see FIG. 6B). After the limiting member 85 is released, the wood processing machine is such that the mounting portion 51 of the wood processing machine 41 moves to the inside of the case body 42 (on the −X direction side in FIG. 3) with respect to the blade holding member 84. The operation of 41 is controlled (see FIG. 3C).

As the mounting portion 51 moves, the chainsaw 44a moves so as to come out from the blade holding portion 92, and the chainsaw 44a is removed from the blade holding member 84. As a result, the cutting process using the chainsaw 44a becomes possible as the cutting process in the wood processing machine 41.

Here, in the moving direction (+ X direction and −X direction) of the blade holding member 84 by the moving mechanism 46, the blade holding portion 92 and the gap forming portion 94 are located with respect to the first rotation shaft 88 in the holding mechanism 45. It is configured to match the direction (+ S direction and −S direction). Further, the gap forming portion 94 is configured to be located on the tip side in the traveling direction to advance to the advance position. Therefore, the movement of the blade holding member 84 by the moving mechanism 46 makes it easy for the chainsaw 44a to greatly advance inside the processing space formed inside the case body 42, and the chainsaw 44a held by the holding mechanism 45 is attached. After being attached to the portion 51, the chainsaw 44a can be advanced toward the processed wood K located inside the processing space.

During the cutting process with the chainsaw 44a, the blade holding member 84 is moved to the standby position by the moving mechanism 46. After the cutting process is completed, the blade holding member 84 is moved to the advanced position again, and the chainsaw 44a is held by the blade holding member 84 (holding mechanism 45) by the movement of the mounting portion 51. Then, after the chainsaw 44a is held by the blade holding member 84, the limiting member 85 is switched to the limiting state. After that, the mounting portion 51 is removed from the chainsaw 44a, and the chainsaw 44a moves to the standby position by the moving mechanism 46.

Here, a detector capable of detecting that the limiting member 85 is in the restricted state (for example, a detector of the operating position of the air cylinder that operates the limiting member 85) is connected to the control device S, and the limiting member 85 limits the limiting member 85. The holding mechanism 45 in which the blade 44 is held may be moved by the moving mechanism 46, provided that the detector detects that the state has been reached. Further, a detector capable of detecting that the blade 44 is held by the blade holding member 84 (for example, a non-contact detection sensor facing the blade holding portion 92) is provided and connected to the control device S to hold the blade. After the detector detects that the cutting tool 44 is held by the member 84, the limiting member 85 may be rotated so as to be in the restricted state.

As described above, during the moving operation of the holding mechanism 45 (cutting tool holding member 84) by the moving mechanism 46, the limiting member 85 is set to the limiting state, so that the cutting tool 44 is in a non-removable locked state. Therefore, even with a heavy blade 44 such as a chainsaw 44a, it is possible to avoid a situation in which the blade 44 comes off from the blade holding member 84 due to the momentum of the moving operation of the blade holding member 84.

Further, the wood processing machine 41 is arranged on the side where the advance position is located (-X direction side) with respect to the standby position, and after moving the chainsaw 44a to the side close to the position where cutting is performed, the blade holding member 84 The chainsaw 44a is removed from the chain saw 44a. Therefore, the chainsaw 44a can be moved in advance to the side close to the position where the cutting process is performed, whereby the time until the start of the processing can be shortened.

Next, as the configuration of the wood processing-related device 40, the arrangement of the standby position of the blade 44 when various types of blades 44 are arranged in the standby position and the configuration related to the moving mechanism 46 will be described.

As shown in FIG. 1, in the wood processing-related device 40, tool stockers 43 are arranged at three locations along the transport path L when viewed from the upper surface side. Specifically, as shown in FIG. 3A, with respect to the first tool stocker 43a and the first tool stocker 43a arranged on the upper part of the case body 42 located in the intermediate portion between the two wood processing machines 41. The second tool stocker 43b arranged on the downstream side (+ X direction side) along the transport path L of the processed wood K and the upstream side (upstream side (+ X direction side) along the transport path L of the processed wood K with respect to the first tool stocker 43a. A third tool stocker 43c arranged on the −X direction side) is provided.

The blade portion 81 of the blade 44 is located on one side of the three tool stockers 43 in the vertical direction, and the main shaft portion 83 is located on the other side. With this arrangement, the cutting tool 44 can be supported in a stable state by the holding mechanism 45 (cutting tool holding member 84). It is not always necessary to arrange the blade portion 81 of the blade 44 on one side in the vertical direction so that the main shaft portion 83 of the blade 44 is located on the other side. As at least a part of the blades 44 provided in the wood processing related device 40, the blades 44 are held so as to include the blades 44 arranged in the standby position so that the blades 81 and the spindle 83 of the blades 44 are aligned diagonally or horizontally. A mechanism 45 may be provided.

Of the three tool stockers 43, the first tool stocker 43a is provided on the upper side of the machining space, the blade portion 81 of the blade 44 is located on the upper side in the vertical direction, and the held portion 82 is below the blade portion 81. And the spindle portion 83 are arranged so as to be located. The shape and size of the blade portion 81 of the blade portion 44 differ depending on the type of processing, and there is a possibility that the blade portion 44 having a larger blade portion 81 is further used after the wood processing-related device 40 is installed. On the other hand, by arranging the blade portion 81 of the blade 44 on the upper side of the machining space and arranging the blade 44 at the standby position so that the blade portion 81 projects upward, the blade portion 81 of the blade 44 is placed in the machining space. It is possible to easily avoid the situation of getting inside. Further, by arranging the blade 44 so that the blade 81 is located on the upper side of the processing space, it is possible to easily approach the blade 44 by utilizing the space on the upper side of the wood processing related device 40. , It is possible to facilitate the maintenance and management of the blade 44.

The second tool stocker 43b is provided at a position overlapping the processed wood K passing through the transport path L on the lower side, and the third tool stocker 43c overlaps the processed wood K passing through the transport path L on the upper side. It is provided at the position. Further, the second tool stocker 43b is arranged on the upstream side of the transport path L with respect to the machining space, and the third tool stocker 43c is on the opposite side of the machining space from the second tool stocker 43b (conveyance path L). It is provided on the downstream side). This makes it easy to place the tool stocker 43 and the cutting tool 44 near the processed wood K where processing is performed by effectively utilizing the space near the processing space, and the second tool stocker 43b and the third tool stocker 43c. It is possible to increase the distance between the two wood processing machines 41 and the blades 44 of the two wood processing machines 41 at the same time.

Of the three tool stockers 43, the first tool stocker 43a is provided with a moving mechanism (not shown) capable of moving the blade 44 in the vertical direction, and is provided in the machining space from above so as to approach the transport path L. The cutting tool 44 advances, and the cutting tool 44 of the wood processing machine 41 is configured to be replaceable. The moving mechanism of the blade 44 of the first tool stocker 43a may include a moving mechanism capable of moving one blade 44 in the vertical direction, or two or more (for example, six) blades 44 may be moved up and down at the same time. It may include a moving mechanism that can be moved. For example, a moving mechanism may be provided so that a total of 48 blades 44 can move up and down in units of six. Further, it is not always necessary to provide a moving mechanism for all the blades 44 stored in the first tool stocker 43a, and the moving mechanism for some of the blades 44 or all the blades 44 may be omitted.

The second tool stocker 43b and the third tool stocker 43c are provided with a moving mechanism 46 so that the blade 44 can advance horizontally toward the inside of the machining space. The second tool stocker 43b and the third tool stocker 43c may store only one blade 44 or two or more blades 44, and store two or more blades 44. In the case of the configuration, the moving mechanism 46 may include a moving mechanism 46 that allows one blade 44 to move, or may include a moving mechanism that allows two or more blades 44 to move at the same time.

Further, as shown in FIG. 3A, the second tool stocker 43b and the third tool stocker 43c are within the height range of the processing space (internal space of the case body 42) of the wood processing machine 41 in the height direction. It is arranged so as to be located in. Therefore, the blade 44 arranged in the second tool stocker 43b and the third tool stocker 43c is such that the blade 44 moves horizontally toward the inside of the processing space, and the blade 44 is attached to the mounting portion 51. It can be attached and detached. Therefore, as compared with the case where a large blade 44 such as a chainsaw 44a is moved in the vertical direction by the moving mechanism 46, the holding mechanism 45 facilitates the holding of the blade 44 and prevents the blade 44 from falling due to the moving mechanism 46. Alternatively, the holding mechanism 45 can be easily manufactured at low cost with a simple configuration.

Further, the large blade 44 such as the chainsaw 44a can be arranged at a position away from the processing space when not in use, so that the processing space of the wood processing machine 41 can be easily set widely, and maintenance work can be performed. The blade 44 (for example, a chainsaw 44a) having a high frequency of use can be arranged at a low position easily accessible from the operator, facilitating maintenance and management, and facilitating the improvement of work efficiency. The movement mechanism 46 does not necessarily have to be provided in the wood processing-related device 40, and may be omitted. Further, the direction in which the holding mechanism 45 can be moved is not limited to the horizontal direction and the vertical direction described above, but may be another direction such as an oblique direction, or the holding mechanism 45 may be in a direction along a predetermined path such as a polygonal line. May be configured to be movable.

Next, the configuration of the chainsaw 44a will be described mainly with reference to FIGS. 7 and 8. FIG. 7 (A) is a perspective view showing a chainsaw 44a and a part (mounting portion 51) of the wood processing machine 41, and FIG. 7 (B) shows mounting the chainsaw 44a with respect to FIG. 7 (A). It is a perspective view which showed the connection part in the state which was connected with the part 51. FIG. 8 is a diagram schematically showing the oil supply device 114 of the chainsaw 44a, in which the outer shapes of the chainsaw 44a and the mounting portion 51 are shown by thin solid lines, the air supply path is shown by a alternate long and short dash line, and the oil supply path is shown. It is shown by a solid line, and the path of a fluid (mist-like oil) in which oil and air are mixed is shown by a dotted line.

The chainsaw 44a is one of the blades 44 that can be used by being attached to the attachment portion 51 of the wood processing machine 41. The chainsaw 44a includes a saw chain 112 as a blade portion 81 in which a plurality of blades 111 for cutting wood (only a part thereof is shown in FIG. 6A) are arranged at regular intervals, and a guide member 113. And is provided, and the saw chain 112 is attached so as to be able to orbit around the guide member 113. The chainsaw 44a is provided with a spindle portion 83 that transmits the rotational power of the saw chain 112 from the wood processing machine 41, and the rotational power of an operating motor (not shown) provided inside the mounting portion 51 causes the spindle portion 83 to be rotated. It is transmitted to the saw chain 112 via. By controlling the operation of the mounting portion 51 of the wood processing machine 41 by the control device S, the position, posture and operation of the chainsaw 44a are controlled, and the wood is cut.

The chainsaw 44a includes a lubrication device 114 that supplies oil (lubricating oil) to the saw chain 112 using compressed air. As the compressed air used in the refueling device 114, the compressed air supplied through the mounting portion 51 of the wood processing machine 41 is used. That is, only when the chainsaw 44a is attached to the attachment portion 51 of the wood processing machine 41, the oil supply device 114 operates to supply oil to the saw chain 112.

It is not always necessary to supply compressed air to the refueling device 114 through the mounting portion 51 of the wood processing machine 41, for example, at a standby position where a holding mechanism 45 (see FIG. 3A or the like) is provided. It may be configured to supply compressed air to the refueling device 114. Further, it is not always necessary to integrally provide the refueling device 114 on the chainsaw 44a. For example, the refueling device 114 can be fixedly or movablely operated separately from the chainsaw 44a in a part of the processing space of the wood processing related device 40. The chainsaw 44a may be arranged and refueled by moving the chainsaw 44a to a position where the refueling device 114 is arranged at a timing when refueling is required.

The wood processing-related device 40 is provided with a compressor as a compressed air supply means (not shown), and the compressed air of the compressor is used to exert various functions in the wood processing-related device 40. For example, compressed air is used when the lock mechanism for connecting and fixing the mounting portion 51 of the wood processing machine 41 and the blade 44 is operated, or when the wood chips around the blade 44 are removed by high-speed air. The compressor is installed on the floor surface outside the case body 42, and goes through a piping route including a route along two moving members 53, 54 (see FIG. 2) from the compressor to the mounting portion 51 of the wood processing machine 41. By doing so, compressed air is transmitted from the compressor to the chainsaw 44a through the mounting portion 51 (specifically, the air path formed inside the mounting portion 51).

The chainsaw 44a includes an oil storage unit 121, a fluid passage unit 124 including a refueling air passage path 124a, and a supply mechanism 123 as a refueling device 114. Further, the fluid passage portion 124 is composed of a piping portion through which any of air, oil, and a mixed gas of air and oil passes as a fluid, and the fluid passage portion 124 is a bendable metal tube. Metal pipes formed inflexibly, internal passages formed inside members, joints connecting a plurality of pipes, and the like are used. As the fluid passage portion 124, other parts such as a resin tube may be used, or any combination may be used according to the type and path of the fluid required for the refueling device 114. Further, in FIG. 7A, the fluid passing portion 124 exposed to the outside of the chainsaw 44a is schematically shown by a dotted line.

The oil storage unit 121 is composed of a storage tank that stores oil (lubricating oil) inside. As shown in FIG. 8, the oil storage unit 121 stores oil from the storage unit 121a forming an internal space, the movable wall 121b forming a part of the outer wall portion of the storage unit 121a, and the movable wall 121b. A protrusion 121c that protrudes to the outside of the tank is provided, and the remaining amount of oil can be detected (confirmed) by the amount of protrusion of the protrusion 121c.

The supply mechanism 123 is a mechanism for supplying a part of the oil stored in the oil storage unit 121 to the refueling air passage path 124a, and is composed of, for example, an air cylinder whose operating state is switched by turning on and off the compressed air. As shown in FIG. 8, a compressor is connected to the supply mechanism 123 via a supply mechanism passage 124c which is a part of the fluid passage portion 124, and the supply mechanism 123 is supplied once by the control of the control valve by the control device S. When the above operation is performed, a certain amount (for example, about 5 ml) of oil is output from the oil storage unit 121 toward the refueling air passage path 124a.

The refueling air passage path 124a is a part of the fluid passage portion 124, and is connected to the compressor via a control valve whose control device S controls the on / off of the output of the compressed air. Compressed air (high-speed air) supplied under the control of the control device S can pass through the refueling air passage path 124a, and the saw chain 112 is configured to be located at the outlet portion of the refueling air passage path 124a.

As shown in FIG. 8, an oil supply path 124b is provided between the oil storage unit 121 and the refueling air passage path 124a, and the oil supply path 124b and the refueling air passage path 124a are connected by a joint 125. .. A check valve 126 is provided in the middle of the oil supply path 124b to prevent oil from flowing back from the refueling air passage path 124a side to the oil storage section 121. When the air cylinder of the oil storage unit 121 is operated once (for example, the movement of the piston for one time), a certain amount of oil is supplied to the refueling air passage path 124a through the oil supply path 124b. It is not always necessary to configure the oil to be supplied to the refueling air passage passage 124a through the oil supply passage 124b, and the fluid so that the oil stored in the oil storage unit 121 is directly supplied to the refueling air passage passage 124a. The passage portion 124 may be configured.

A certain amount of oil that has entered the refueling air passage path 124a is supplied toward the outlet 127 of the refueling air passage path 124a. In this case, the oil is supplied in a state where the air is passing through the refueling air passage path 124a at high speed, so that the oil is atomized little by little toward the outlet 127 of the refueling air passage path 124a. To proceed. A portion between the saw chain 112 and the guide member 113 is located at the outlet 127 of the refueling air passage path 124a, and mist-like oil is sprayed on the portion between the saw chain 112 and the guide member 113. It is not always necessary to spray oil toward the portion between the saw chain 112 and the guide member 113, and oil may be supplied toward the saw chain 112.

The timing of injecting oil into the oil storage unit 121 can be determined by the operator visually confirming the amount of protrusion of the protrusion 121c provided in the oil storage unit 121. It should be noted that a sensor for detecting the amount of protrusion of the protrusion 121c is provided and detected, and the time when the remaining amount of oil is low is detected through the state of the sensor by the control of the control device S, and the information corresponding to the state where the display device is low in oil. (For example, a display such as "low oil level") may be output as necessary to notify the oil replenishment time.

The injection of oil into the oil storage unit 121 is carried out by removing the joint connecting the oil storage unit 121 and the oil supply path 124b. In addition to the oil supply path 124b, an inlet portion for injecting oil into the oil storage unit 121 may be provided so that the oil can be injected into the oil storage unit 121.

Next, an example of refueling the chainsaw 44a using the refueling device 114 will be described. The refueling to the chainsaw 44a using the refueling device 114 is executed by controlling the supply of compressed air by the control program of the control device S. Further, refueling of the chainsaw 44a is executed between the time when the chainsaw 44a is attached to the attachment portion 51 until the cutting process is performed, and during the cutting process in the state where the chainsaw 44a is attached to the attachment portion 51. To.

First, the operations of the mounting portion 51 and the moving mechanism 46 are controlled so that the chainsaw 44a is mounted on the mounting portion 51, and the chainsaw 44a is mounted on the mounting portion 51 (state of FIG. 7B). After that, the output of the compressor is controlled so that the air passes through the refueling air passage path 124a toward the outlet 127. Further, the rotation of the spindle portion 83 is controlled so that the saw chain 112 rotates.

When air passes through the refueling air passage path 124a and the saw chain 112 is in a rotated state, the supply mechanism 123 is operated once while maintaining that state, and the oil stored in the oil storage unit 121 is discharged. , A certain amount is supplied from the oil supply path 124b to the refueling air passage path 124a. As a result, a certain amount of oil is atomized and sprayed onto the saw chain 112 by the air supplied by the compressor. The timing for controlling the air to pass through the refueling air passage path 124a does not necessarily have to be before the oil is supplied to the refueling air passage path 124a, and the passage of the air is started after the oil is supplied. It may be controlled so that the passage of air is started at the same time as the supply of oil or during the supply of oil.

After a certain period of time (for example, 2 seconds) has elapsed from the previous operation of the supply mechanism 123, the supply mechanism 123 is operated once again, and a certain amount of oil is atomized and sprayed onto the saw chain 112 again. Be done. By repeating this operation a plurality of times (for example, three times), a certain amount of oil supplied by the supply mechanism 123 is atomized and supplied to the saw chain 112 repeatedly.

The refueling of the saw chain 112 may be performed with the chainsaw 44a stopped at a fixed position, or may be performed using the period during which the chainsaw 44a is moved. For example, the saw chain 112 may be refueled by utilizing the movement period during which the chainsaw 44a is moved from the standby position to the position where the processed wood K is first processed, whereby the processing time of the processed wood K may be used. Can be easily shortened.

Further, when refueling the saw chain 112 while the chainsaw 44a is moving, whether or not a moving time of at least a predetermined time (for example, 10 seconds) required for refueling can be secured before the start of the next cutting process. In addition, the control device S determines whether or not refueling is possible by operating the supply mechanism 123 more than a predetermined number of times (for example, 3 times), and refueling is performed during a certain movement period during that time. You may.

Further, when the cutting process is started, the wood chips are scattered, and if oil is supplied during the cutting process, mist-like oil adheres to the wood chips, and the processed wood K is contaminated by the wood chips to which the oil adheres. there is a possibility. Therefore, it may be controlled so that refueling is not performed during cutting. For example, the control device S can detect the current value of the motor that rotates the saw chain 112 and determine whether or not cutting is in progress. However, if the current value is a value corresponding to the cutting of wood, refueling may be limited, and if the current value is a value during idling, refueling may be performed. In this case, if the machining is started during the refueling, the refueling may be controlled to be finished at the timing when the refueling by the operation of the supply mechanism 123 for one time is finished, or the machining may be started. If it is detected, it may be controlled to end (stop) refueling even during the refueling operation.

In this way, the oil supplied to the refueling air passage path 124a by the operation of the supply mechanism 123 is supplied to the saw chain 112 in small amounts in the form of mist using the air of the compressor. Therefore, it is possible to prevent the contact portion between the saw chain 112 and the guide member 113 from becoming too hot, and it is easy to avoid a situation in which the oil supplied to the saw chain 112 adheres to the processed wood K during cutting. can do.

Further, by the operation of the supply mechanism 123 a plurality of times, the oil supplied from the oil storage unit 121 is divided into a plurality of times little by little and atomized and supplied to the saw chain 112. Therefore, the concentration of oil in the atomized fluid in which air and oil are mixed can be lowered to supply oil to the saw chain 112, and it is possible to easily supply oil to the entire saw chain 112.

Further, as a power source of the air cylinder constituting the supply mechanism 123, a compressor used when spraying oil is used. Therefore, a part of the air piping provided in the wood processing machine 41 can be shared between the air cylinder and the oil spraying, and the air piping can be easily simplified. Further, by using air as a power source, the supply mechanism 123 can be made lighter than using a motor or the like, and the weight increase of the chainsaw 44a using the saw chain 112 can be suppressed to move the blade 44 at high speed. It can be easily realized.

Further, when the chainsaw 44a is attached to the attachment portion 51 of the wood processing machine 41, the air supplied by the compressor is supplied to the refueling air passage path 124a, and a part of the oil is sprayed on the saw chain 112. Therefore, the rotation of the saw chain 112 at the time of refueling can use the power of cutting by the wood processing machine 41, and the power required for refueling the refueling device 114 is the connection of the blade 44 to the mounting portion 51. Can be secured through. Therefore, in order to add the refueling function to the chainsaw 44a, it is possible to eliminate the need for a dedicated power source, pipe connection control, etc., and the refueling function can be added to the chainsaw 44a at low cost by using a simple structure and control. Can be made easier.

Next, the configuration of the connecting portion between the chainsaw 44a and the mounting portion 51 will be described mainly with reference to FIGS. 7 and 8. In the chainsaw 44a, the spindle portion 83 is inserted into the mounting hole 131 and the two guide pins 132 are inserted into the two guide holes 133 to be connected to the mounting portion 51 of the wood processing machine 41. The two guide pins 132 are arranged at positions apart from the rotation center axis C of the spindle portion 83 with respect to the spindle portion 83. The two guide pins 132 are arranged at positions separated by an angle of approximately 90 degrees with respect to the rotation center axis C of the spindle portion 83. The two guide pins 132 and the spindle portion 83 are configured to support the rotation of the chainsaw 44a around the spindle portion 83.

Here, although only one guide pin 132 may be provided, it is preferable that the guide pin 132 is provided at two or more locations around the rotation center axis C of the spindle portion 83. As a result, the tip of the saw chain 112 is likely to generate a resistance force against a large rotational moment acting on the chainsaw 44a located far away from the spindle portion 83, and the connecting portion between the chainsaw 44a and the mounting portion 51 is easily generated. Can be easily formed into a small size and the degree of freedom in cutting can be increased.

Further, as shown in FIG. 7, both of the guide pins 132 are formed in a rod shaft shape having a substantially circular cross-sectional shape, and the guide holes 133 have a substantially circular cross-sectional shape that is substantially the same as the guide pin 132. It has a hole shape. The guide pin 132 and the guide hole 133 are not limited to a substantially circular cross-sectional shape, and may be capable of resisting rotation of the chain saw 44a about the spindle portion 83. For example, the guide hole 133 has an oval cross-sectional shape. Or, it may be formed in a groove shape that is continuous in the direction away from the rotation center axis C of the spindle, or may be formed in another shape.

Further, inside the guide pin 132, a part of the fluid passage portion 124 through which the air of the compressor passes is provided in the central shaft portion of the guide pin 132. Specifically, one guide pin 132 is formed with a part of the refueling air passage path 124a, and the other guide pin 132 is formed with a part of the supply mechanism passage 124c. As a result, it is possible to connect the compressed air passage by the connecting operation between the chainsaw 44a and the mounting portion 51.

Here, a tubular rubber member 134 that can be deformed by contacting the deep bottom portion of the guide hole 133 is provided at the tip portion (lower end portion of FIG. 7A) of the guide pin 132 in the protruding direction. When the guide pin 132 is inserted into the guide hole 133, the rubber member 134 is compressed and slightly deformed, and the deformed rubber member 134 constitutes a part of the air pipe. This makes it possible to suppress air leakage between the guide pin 132 and the mounting portion 51.

Next, the treatment of wood chips generated by cutting by the wood processing machine 41 will be described. As a wood waste processing device by the wood processing related device 40, a first belt conveyor is provided under the processed wood K arranged at the processing position, and processing is performed from the lower side of the processing space along the direction of the transport path L. It is preferable to configure the wood chips to be discharged to the outside (for example, the side of the downstream transfer device 30b) that is out of the bottom of the space. If the processed wood K having a large cross-sectional shape is configured to be machineable, the horizontal width of the transport path L will also be wide, so the wood chips will be sent to the outside using the space below the transport path L. It is preferable to allow the wood to be discharged because it is possible to suppress the increase in size of the wood precut processing apparatus 10. Further, two belt conveyors for transferring wood chips from the side close to the two wood processing machines 41 toward the lower side of the transport path L are provided for the first belt conveyor, and the wood chips are transferred to the first belt conveyor. May be transportable. The wood chips can be transferred by the first belt conveyor, including the wood chips that have fallen to a position close to the wood processing machine 41 on the lower side of the processing space.

Further, as a wood waste processing device, a second belt conveyor is provided on the downstream side of the first belt conveyor in a direction continuous with the transport path L, and the wood chips discharged from the second belt conveyor are provided. It may be in a state of being put together. Here, it is preferable that the wood chips are sorted according to their size. For example, small wood chips are collected by using a dust collector that sucks the wood chips from the top of the second belt conveyor by negative pressure from the lateral or upward direction. It may be collected in the middle of transportation on the second belt conveyor, and a collection box capable of accommodating a certain amount of large wood chips (wood ends) may be provided at the discharge destination of the second belt conveyor to collect the large wood chips.

Further, the second belt conveyor has a structure having a continuous section diagonally upward so as to raise the wood chips to a certain height position, and the wood chips raised to a certain height are dropped onto a filter such as a wire mesh. Large wood chips that do not pass through the filter can be collected manually by remaining on the filter, and small wood chips that have fallen under the wire mesh can be collected from the side with respect to the space under the wire mesh. It may be collected by using a dust collector that sucks in.

The present invention is not limited to the above embodiment, and it can be easily inferred that various improvements and changes can be made without departing from the spirit of the present invention. For example, the present invention will be described below. In this case, each configuration described below may be applied to the above embodiment, or a plurality of configurations described below may be combined with respect to the above embodiment. May be applied.

For example, the wood precut processing apparatus 10 does not necessarily have to have the above-mentioned configuration, and some configurations may be different. For example, it is not always necessary to have two wood processing machines 41 having the same shape, and the two wood processing machines 41 may be configured with different sizes and shapes.

Further, in addition to the two wood processing machines 41, another wood processing machine may be provided. For example, as the wood processing machine 41, another wood processing machine may be installed between the transfer device 30 and the loading device 20 so that both end portions of the processed wood K in the longitudinal direction are processed in advance. In this case, it is preferable that the length of the processed wood K in the longitudinal direction is measured by the transport device 30 after the processing of both end portions of the processed wood K in the longitudinal direction is performed.

Further, in the above embodiment, a case has been described in which a power source is provided in the lower transport portion 31 so that the processed wood K can be transported by rotating the roller 72, but the roller 72 is not necessarily a power source for a motor or the like. It is not necessary to configure it so that it can be rotated by. The roller 72 of the lower transport unit 31 is composed of a freely rotatable free roller, and the processed wood K cannot be moved only by the lower transport unit 31, but the processed wood K is moved by the upper transport unit 32. You may.

Further, in the above embodiment, a holding mechanism including a wood processing machine 41 having two moving members 53 and 54, a clamp 73 (clamp operating unit 74) whose position can be detected by a detector, and a limiting member 85. The wood precut processing device 10 including the 45 and the chainsaw 44a provided with the refueling device 114 has been described. May have a different configuration, and even in that case, it is possible to provide the wood precut processing device 10 which has an effect corresponding to the remaining one or more devices. Therefore, for example, the wood processing machine 41 may be configured to use an articulated robot that controls the movement of the position of the mounting portion 51 by rotating the arm portion, or the clamp 73 in the upper transport portion 32 as the transport device 30. It may be configured not to have a detector capable of detecting the position of.

Further, in the above embodiment, the configuration in which one check valve 126 is used as the refueling device 114 of the chainsaw 44a has been described, but the chainsaw 201 provided with the refueling device 202 provided with another check valves 211 and 212 is used as a blade. It may be configured to be usable as 44. In the following, a configuration example of the refueling device 202 according to another embodiment will be described with reference to FIGS. 9 and 10.

FIG. 9 is a perspective view showing the chainsaw 201 according to another embodiment, and FIG. 10 is a diagram showing a refueling device 202 of the chainsaw 201 according to another embodiment. In the following description, only the components different from the refueling device 114 of the chainsaw 44a according to the above-described embodiment will be described, and the description of the same configuration will be omitted.

The refueling device 202 of the chainsaw 201 is provided with three check valves 126, 211, and 122. The first check valve 126 is provided between the oil storage unit 121 and the refueling air passage path 124a, as in the above embodiment. When the pressure exceeds a certain pressure (for example, 0.05 MPa), the first check valve 126 opens the oil supply path 124b so that the oil can proceed to the side of the joint 125, and when the pressure becomes less than a certain pressure, the oil becomes oil. Block the supply path 124b. As a result, it is possible to easily avoid a situation in which oil advances to the side of the joint 125 and flows into the refueling air passage path 124a after the operation of the supply mechanism 123.

The second check valve 211 is provided in the middle of the refueling air passage path 124a, and specifically, the side closer to the compressor (upstream side) than the joint 125 where the oil supply path 124b and the refueling air passage path 124a meet. ). The second check valve 211 is preferably provided near the joint 125 and near the portion where the oil supply passage 124b joins the refueling air passage passage 124a (hereinafter, also referred to as a “merging portion”). For example, it is preferable that the second check valve 211 is directly screwed and fixed to the upstream side where the compressor is located with respect to the metal part of the joint 125. By providing the second check valve 211, it is possible to limit the space of the refueling air passage path 124a on the upstream side of the confluence to a small size and prevent the oil from advancing to the upstream side of the joint 125. ..

The third check valve 212 is provided as part of the supply mechanism 123. Specifically, the third check valve 212 is provided in the passage portion connecting the internal space 121d in which the fluid (air) pressing the movable wall 121b is stored and the supply mechanism passage 124c, and is provided in the internal space 121d. Allows the fluid to travel from the feed mechanism passage 124c to the supply mechanism passage 124c and blocks the fluid from traveling in the opposite direction. A throttle valve 213 is provided at a location where the third check valve 212 is provided as a part of the supply mechanism 123, and the fluid is allowed to flow into the internal space 121d through the throttle valve 213. For example, as the third check valve 212, a speed controller in which a check valve is added to the throttle valve can be used.

By controlling the pressure of the compressor by the control device S, a required amount of fluid enters the internal space 121d from the supply mechanism passage 124c through the throttle valve 213. As a result, the space of the oil storage unit 121 (storage unit 121a) can be reduced by a required amount, and oil can be supplied to the refueling air passage path 124a. Further, after the pressure stop control of the compressor is performed, the pressure in the internal space 121d is immediately reduced through the third check valve 212. Therefore, it is possible to reduce the possibility that the oil will continue to be supplied through the first check valve 126 because the pressure in the internal space 121d does not decrease after the pressure stop control of the compressor is performed.

The refueling device 202 may be provided with a check valve different from the check valve described above. For example, the check valve is constant between the joint 125 and the outlet 127 toward the outlet 127 side (downstream side). A check valve may be provided so as to allow the passage of the fluid when the pressure exceeds the above pressure and prevent the passage of the fluid toward the side (upstream side) of the joint 125. This also makes it easy to avoid a situation in which oil leaks from the outlet 127 after refueling by the operation of the compressor.

Further, the plurality of check valves related to the refueling device 202 described above may be provided as necessary according to the range of movable (rotational) operation of the chainsaw 201, the operating speed, the type of oil, and the like. It is not always necessary to provide all of them, and some of them may be omitted. Even in this case, it is possible to provide the wood precut processing device 10 that can use the chainsaw 201 provided with the refueling device 202 that has an effect corresponding to the provision of a part of the check valve.

Further, in the above embodiment, as the control of refueling to the saw chain 112 by the control of the control device S, the timing of advancing the oil to the side of the joint 125 through the first check valve 126 is the refueling air passage path 124a. This is not limited to the case where the air is passing at high speed, but the case is not limited to this, and in the situation where the oil is advancing to the side of the joint 125 through the first check valve 126, the refueling air passage path is used. The pressure may be controlled so that the air does not pass through the 124a at high speed. For example, the pressure may be controlled so that the air passes at a lower speed than the state where the atomized oil is output, or the pressure is low so that the air does not move. May be. Then, after the first check valve 126 is closed so that the oil does not proceed, the atomized oil advances toward the outlet 127 by controlling the pressure so that the air passes through the refueling air passage path 124a at high speed. You may do so.

For example, the control of advancing the oil to the side of the joint 125 through the first check valve 126 is executed for about 0.1 seconds to supply the oil, and then the air passes through the refueling air passage path 124a at high speed to fog. It may be controlled so that the oil in the form is output. Further, the output of the atomized oil after the supply of the oil may continuously execute the output of air at high speed for a certain period of time (for example, 10 seconds), but the output of air at high speed may be intermittently performed. It is preferable to carry out. For example, the output of air at a high speed for a predetermined output time (for example, 2 seconds) and the stop of the output of air for a predetermined stop time (for example, 2 seconds) are repeated a fixed number of times (for example, 5 times). It may be controlled to. Due to the intermittent air output, the oil output to the side of the joint 125 is intermittently sprayed onto the saw chain 112 multiple times, so that the oil is applied to the entire saw chain 112 in a nearly uniform manner. It can be easily supplied.

Further, after the output of the mist-like oil is executed, after a certain interval time, the oil is supplied to the side of the joint 125 again, and then the control to output the mist-like oil is executed in order. You may do so. For example, the control of executing the high-speed air output once for one oil supply may be repeated a plurality of times, or the high-speed air output may be intermittent for one oil supply. The control to be executed a fixed number of times (for example, three times) may be repeated a plurality of times.

Further, it is preferable that the saw chain 112 in the above embodiment is reliably refueled before the start of machining by the chainsaw 201. For example, refueling is performed in synchronization with the timing at which the saw chain 112 starts to rotate. May be configured to perform control of. Specifically, oil to the side of the joint 125 synchronizes with the start of rotation of the saw chain 112 so that the atomized oil is sprayed after the saw chain 112 starts to rotate and reaches a certain rotation speed. Supply control may be performed so that refueling may be executed. As a result, when machining with the chainsaw 201 is executed, the saw chain 112 can always be refueled, and when a certain amount of machining with the chainsaw 201 is performed, the rotation of the saw chain 112 is temporarily stopped. It is possible to refuel the saw chain 112 simply by setting the control.

Further, a throttle valve (speed controller) may be provided near the outlet 127 and the outlet 127 of the refueling air passage path 124a in the above embodiment. As a result, it is possible to spray the oil toward the saw chain 112 at a higher speed while keeping the flow velocity low in the portion where the oil and the air become a mixed gas.

As described above, the present invention is suitable for a wood processing device capable of processing wood.
