The angle formed by the above two tangent planes is set to be slightly larger (for example, 1 degree or more and 5 degrees or less) than the angle formed by the two side surfaces of the processed material 100'. The processed material 100 is supported by the lower left protruding portion 32L and the lower right protruding portion 32R, and either one of the upper left protruding portion 33L or the upper right protruding portion 33R suppresses rotational deviation in the arrangement of the processed material 100. You may do so. On the contrary, an angle slightly smaller than the angle formed by the two side surfaces of the processed material 100 (for example, 1 degree or more and 5 degrees or less) is set as the angle formed by the two tangent planes, and the processed material 100 is mainly placed on the upper left. It may be supported by the side protruding portion 33L and the upper right side protruding portion 33R, and either one of the lower left protruding portion 32L and the lower right protruding portion 32R may suppress the rotational deviation in the arrangement of the processed material 100. ..

Further, the second support portion 30b does not necessarily have the same configuration as the first support portion 30a, and the processed material 100'of the ideal shape is the first support in the axial direction along the longitudinal direction of the processed material 100. As long as the shape can be supported by the portion 30a and the second support portion 30b in a non-rotatably stable state, different shapes may be formed.

The first support portion 30a and the second support portion 30b are planes that are continuous in the longitudinal direction of the processed material 100 on the surface of the processed material 100 when the position of the surface of the processed material 100 is detected as a measurement state. It is configured to support the lower side of two side surfaces 100L and 100R which are shaped and face substantially orthogonal to each other. That is, the angle formed by the tangential plane in contact with the lower left protruding portion 32L and the upper left protruding portion 33L and the tangential plane in contact with the lower right protruding portion 32R and the upper right protruding portion 33R is substantially the same as the cross-sectional shape of the processed material 100. It is designed to be at a right angle.

The cross-sectional shape of the processed material 100 is not limited to a square shape as shown in FIG. 2 (A), and when the processed material has a shape such as a regular octagon in the axial direction, two pieces are separated from each other. The lower left side support portion 31L and the lower right side support portion 31R may be configured so as to be able to support the lower sides of the two side surfaces that face substantially orthogonal directions.

Further, the structure is not limited to the configuration in which the lower sides of the two side surfaces 100L and 100R of the processed material 100 facing substantially orthogonal directions are supported to perform the curvature measurement, and the lower side of the processed material is formed by two other angled surfaces. It may be configured to support and perform the curvature measurement. For example, when the cross-sectional shape of the processed material is a regular hexagon, the tangential plane in contact with the lower left protruding portion 32L and the upper left protruding portion 33L and the tangential plane in contact with the lower right protruding portion 32R and the upper right protruding portion 33R. The angle between the two surfaces may be designed to be approximately 120 °, and the boundary between the two sides may be arranged so as to be located on the lower side in the vertical direction so that the two adjacent surfaces are supported, or the two surfaces may be supported. The angle between the tangent planes is designed to be approximately 60 °, with the downward facing sides facing vertically downwards and supporting two separate sides located on either side of the downward facing sides. It may be configured.

The position detection devices S1, S2a, and S2b have at least two surfaces separated in the circumferential direction with respect to a part of the processed material 100 located between the first support portion 30a and the second support portion 30b. When the processed material 100 is curved (warped), it is possible to output a detection result corresponding to the direction of the curvature and the magnitude of the curvature. Specifically, as shown in FIG. 2A, the position detection devices S1, S2a are combined with two laser displacement meters 41L and 41R arranged at each position where the position detection devices S1, S2a and S2b are provided. , S2b are each configured.

The laser displacement meter 41L and the laser displacement meter 41R are arranged so that the positions of the surfaces can be detected one by one with respect to each of the two side surfaces 100L and 100R of the processed material 100. In detail, the processing of an ideal shape is performed. The material 100'is configured to be capable of measuring the deviation (displacement amount) with respect to the surface position, whereby the positions of two surfaces separated in the circumferential direction can be detected.

The side surface for detecting the position of the surface is not limited to the two side surfaces 100L and 100R supported by the first support portion 30a and the second support portion 30b on the lower side of the processed material 100, and the other two side surfaces. For example, it may be a combination of two side surfaces facing the upper side (upper right side and upper left side) of the processed material 100, and two facing the upper right side and the lower right side of the processed material 100. It may be a combination of sides. In this case, if the side surface for detecting the position of the surface is a combination of two side surfaces facing in completely opposite directions, the deviation (amount of deviation) with respect to the position of the surface will be the measurement result along the same direction. Since there is a possibility that the measurement results will be almost the same, it is preferable to use two sides excluding the combination of the two sides facing completely opposite directions, and the side surface is orthogonal to the side or the direction to be orthogonal to each other. It is preferable to use a combination of two sides facing the side in the near direction.

When the position of the surface of the processed material 100 is detected by the laser displacement meters 41L and 41R constituting the position detection devices S1, S2a and S2b, the processed material 100 has the first support portion 30a and the second support in the longitudinal direction thereof. It is arranged so as to be substantially the same as the direction of separation from the portion 30b. Further, the processed material 100 is arranged so that the center position in the longitudinal direction thereof is substantially the same as the center position in the separation direction between the first support portion 30a and the second support portion 30b, and is close to both ends of the processed material 100. At the position, the processed material 100 is configured to be supportable by the first support portion 30a and the second support portion 30b.

When the contour shape (cross-sectional shape) of the processed material 100 is quadrangular, the position of the surface is detected with respect to two different side surfaces, but when it is a polygon of pentagon or more, two or more are detected. The curvature measurement may be performed by detecting the position of the surface with respect to the side surface of the polygon. Further, when the cross-sectional shape of the processed material 100 includes a curved surface shape such as an elliptical shape, the curvature measurement is executed by detecting the position of the surface which is not a combination of two places facing completely opposite directions at at least two places. In this case, it is preferable to detect the positions of the two surfaces facing the orthogonal direction side or the direction side closer to the orthogonal direction side.

The position detection devices S1, S2a, and S2b are arranged apart along the direction in which the first support portion 30a and the second support portion 30b are separated from each other (longitudinal direction of the processed material 100'). Specifically, three laser displacement meters 41L for measuring the position of the surface of the side surface 100L facing the lower left side and three laser displacement meters 41R for measuring the position of the surface of the side surface 100R facing the lower right side are the first. The position of the surface corresponding to the overlapping position in the axial view is detectable so as to be separated from the support portion 30a and the second support portion 30b along the separation direction.

Therefore, the three laser displacement meters 41L can detect the positions of the surfaces at three points on a straight line along the longitudinal direction with respect to the side surface 100L facing the lower left side of the processed material 100 in the axial direction. Further, the three laser displacement meters 41R can detect the positions of the surfaces at three points on a straight line along the longitudinal direction with respect to the side surface 100R facing the lower right side of the processed material 100 in the axial direction.

The height and orientation of the three laser displacement meters 41L are set so that the detection position is an intermediate position in the width direction orthogonal to the longitudinal direction with respect to the side surface 100L of the processed material 100. Similarly, the heights and orientations of the three laser displacement meters 41R are set so that the detection position is the middle position in the width direction orthogonal to the longitudinal direction with respect to the side surface 100R of the processed material 100. There is. For this reason, when the first support portion 30a and the second support portion 30b have a rotational deviation around the axis of the processed material 100 along the longitudinal direction, that is, the processed material 100 is deformed into a twisted shape in the axial direction. Even if this is the case, the detection error based on the rotation deviation can be suppressed as compared with the case where the detection position is separated from the intermediate position.

The position detection device S1 is provided so as to be located near the center of the first support portion 30a and the second support portion 30b along the separation direction (longitudinal direction of the processed material 100'). As a result, the position of the surface can be detected near the center of the side surfaces 100L and 100R of the processed material 100, and in the vicinity of the center of the processed material 100, which is generated as the largest amount of deviation when curved with a constant curvature. The amount of deviation from the ideally shaped processed material 100'can be measured.

The amount of deviation may be measured by a sensor capable of detecting a difference (deviation) in the position of the surface of the processed material 100, and various sensors capable of measuring the distance from the sensor to the surface of the processed material 100. Can be used. For example, the laser displacement meter 41R as a sensor emits inspection light of the optical path VR toward the processed material 100, measures the light reflected on the surface of the processed material 100, and measures the optical path VR of the processed material 100 with respect to the processed material 100'. The amount of deviation in the direction along the line can be measured. Further, the detection of the position of the surface of the processed material 100 is not limited to the configuration of detecting using a laser, and other non-contact type light rays (infrared rays) may be used, or the surface of the processed material 100 is in contact with the surface. The position of the surface may be detected. Further, the detection of the surface position of the processed material 100 does not necessarily have to be configured to detect the position of the surface at one point, and may be configured to detect the position of the surface of two or more points, linearly or planarly. It may be configured to detect the position of the surface. When the processed material curvature detection device 4 is provided with position detection devices (laser displacement meters) at a plurality of locations, sensors having a common configuration may be used, or a plurality of types of sensors having different methods may be combined.

Further, in detecting the position of the surface of the processed material 100, it is not necessary to detect the position of each surface with one device (sensor), and a plurality of positions of the surface of the processed material 100 are detected by a plurality of sensors (for example, limit switches). It may be possible to detect in the range divided into. For example, a switch that is turned on when the surface is located on the side away from the position detection device S1 by more than 1 mm with respect to the ideal shape, and a direction side closer to the position detection device S1 than 1 mm with respect to the ideal shape. A switch that turns on when the surface is located is provided separately, and if any switch is on in the measurement state, it is detected that it is curved to the turned on side. If neither switch is on, it may be detected that the deviation amount is within the range of ± 1 mm with respect to the ideal shape.

When the position detection device S1 executes the curvature measurement with the first support portion 30a and the second support portion 30b in the measurement state in which both ends in the longitudinal direction of the processed material 100 are supported, the position detection device S1 (laser displacement meter 41L) And, based on the detection result of the laser displacement meter 41R), the bending direction and the bending magnitude of the processed material 100 can be easily detected. In this case, since the magnitude of the curvature with respect to the distance supported by the first support portion 30a and the second support portion 30b (the length of the support section) can be detected, the length of the support section can be detected. From the ratio of the length to the length of the processed material 100, the magnitude of the curvature with respect to the total length of the processed material 100 can be estimated.

The position detection device S2a is provided at a position closer to the first support portion 30a than the position detection device S1. Further, the position detection device S2b is provided at a position closer to the second support portion 30b than the position detection device S1. The detection results of these position detection devices S2a and S2b detect, for example, the position of the surface of the processed material 100 in the vicinity of the first support portion 30a and the second support portion 30b, and the position shifts by more than a predetermined amount. If so, it is determined that the processed material 100 is not correctly supported by the first support portion 30a and the second support portion 30b, and the accurate surface position cannot be measured, and the first support portion 30a and the second support portion 30a and the second support portion 30a are determined. The program of the control device 6 may be configured so that the support portion 30b and the support portion 30b are operated to change the support state of the processed material 100 and the curvature measurement is performed again.

The misalignment of the processed material 100 may be detected based on the detection results of the position detection devices S2a and S2b. For example, the program of the control device 6 is configured so as to detect that the first support portion 30a is separated from the lower left support portion 31L and correct the detection result of the position detection device S1 in consideration of this arrangement deviation. You may. As a result, it is possible to omit re-execution of the curvature measurement for the processed material 100, shorten the time for the curvature measurement, and improve the detection accuracy of the curvature direction and the curvature size of the processed material 100. It will be possible.

Further, when the rotational deviation around the axis along the longitudinal direction of the processed material 100 is a certain amount or more, the detection result of any of the position detection devices S2a and S2b may be larger than a certain value, and these positions Based on the detection results of the detection devices S2a and S2b, it may be detected whether or not the rotational deviation about the axis along the longitudinal direction of the processed material 100 exists in a certain amount or more. The position detection devices S2a and S2b may be configured to detect the rotation deviation with higher accuracy. For example, at the positions where the position detection devices S2a and S2b are arranged in the longitudinal direction, the side surfaces 100L and 100R may be configured. The positions of two or more surfaces separated in the width direction are detected, and the displacements of the surfaces of the four corners on both ends along the longitudinal direction of each side surface 100L and 100R are detected to detect the rotational deviation. May be good. Further, the position of the surface in the width direction is detected linearly or planarly on at least one of both ends along the longitudinal direction of each side surface 100L and 100R, and the rotation deviation is detected using the detection result. May be good.

Further, the position detecting devices S2a and S2b may detect the position of the surface between the position detecting device S1 and the two support portions 30a and 30b. In this case, the curvature of the curvature is not constant, the curvature is partially generated, or the shape deviates greatly from the ideal shape at a position deviated from the middle in the longitudinal direction instead of the intermediate portion of the processed material 100. When is occurring, the situation can be easily detected. In addition, the position detection devices S2a and S2b are further provided between the two support portions 30a and 30b so that it is possible to detect whether or not they are correctly supported by the support portions 30a and 30b. , The deviation of the surface position at a position different from the intermediate portion of the processed material 100 may be detected, or the state of curvature may be detected in more detail.

Further, it is not necessary to detect the position of the surface of the processed material 100 only between the support portions 30a and 30b. For example, as shown in FIG. 2B, the position detection devices S3a and S3b may be provided so as to be located outside the support portions 30a and 30b. In this case, the position of the surface near both ends of the processed material 100 is measured, the detection result of the position detecting device S1 with respect to the central portion of the processed material 100, and the processed material 100 by the position detecting devices S3a and S3b. The magnitude of the curvature and the direction of the curvature of the processed material 100 can be estimated from the detection results for both ends.

Further, as shown in FIG. 2B, another position detecting devices S4a and S4b are provided so as to be located closer to the two support portions 30a and 30b with respect to the position detecting devices S3a and S3b. May be good. In this case, when the curvature of the processed material 100 is not constant, the shape of the curvature can be easily estimated from the detection results of the position detecting devices S4a and S4b. Further, the position detection devices S4a and S4b may be arranged so as to be located at both ends of another processed material whose length is set shorter than that of the processed material 100. In this case, the lengths are set to a plurality of types. With respect to the curvature of the processed material, it is possible to measure the curvature using the detection result of the position of the surface at a position close to both ends, and it is possible to detect the state of curvature more accurately.

As the position detecting device S1 located at the central portion of the two support portions 30a and 30b, the position detecting device S1 includes a laser displacement meter capable of detecting the positions of two or more surfaces close to the central portion displaced in the longitudinal direction. May be configured. Further, the position detection devices S1 located between the support portions 30a and 30b, the position detection devices S2a and S2b located between the support portions 30a and 30b on both ends of the position detection device, and the support portions 30a and 30b. The configuration may include all of the position detection devices S3a, S3b, S4a, and S4b located on the outside, or a part of the position detection devices may be omitted.

Further, at least one of the position detection devices S1, S2a, S2b, S3a, S3b, S4a, and S4b can be moved along the longitudinal direction of the processed material 100, and in this case, the operation mechanism including the motor and the like is controlled by the control device. It may be controlled by 6 and electrically movable, or the operator may manually move it, for example, a position detecting device may be attached to a sliding rail to enable the moving operation. Further, the lasers constituting the position detection devices S1, S2a, S2b, S3a, S3b, S4a, S4b electrically or by the operator's operation in the width direction of the side surfaces 100L and 100R where the position of the surface of the processed material 100 is measured. The displacement meters 41L and 41R may be movable so that the center in the width direction can be measured even for processed materials having different widths, or the position near one end side in the width direction of the processed material 100 can be measured. The positions of a plurality of surfaces in the width direction of the above may be detected by one laser displacement meter.

Further, at least one of the laser displacement meters 41L and 41R constituting each of the position detection devices S1, S2a, S2b, S3a, S3b, S4a and S4b is configured by one laser displacement meter in the axial direction of the processed material 100. It may be configured to be movable in the left-right direction in the visual sense. That is, the position detection device may be movable in the left-right direction in the axial direction on the lower side of the processed material 100, and the drive mechanism including the motor or the like may be controlled by the control device 6 to be electrically movable. The positions of the surfaces of the side surfaces 100L and 100R may be detectable.

Further, based on the detection results of the positions of two or more surfaces of the position detection devices S1, S2a, S2b, S3a, S3b, S4a, and S4b, not only the curvature of the side surfaces 100L and 100R of the processed material 100 but also the curvature of the side surfaces 100L and 100R of the processed material 100. The curved shape of the side surfaces 100L and 100R of the processed material 100 may be estimated.

As shown in FIG. 2, the drive mechanisms 34a and 34b include a mechanism for operating the first support portion 30a and the second support portion 30b, and a drive source such as a motor or a pneumatic cylinder for operating the first support portion 30a and the second support portion 30b. It is a device configured in. The drive mechanisms 34a and 34b are separately provided for each of the two support portions 30a and 30b. The drive mechanisms 34a and 34b may be configured by one drive mechanism common to the two support portions 30a and 30b.

The drive mechanism 34a is a mechanism for operating the first support portion 30a, and is a lower left support portion 31L (lower left protrusion 32L and upper left protrusion 33L) and a lower right support 31R (right) in the first support 30a. At least one of the lower protrusion 32R and the upper right protrusion 33R) can be operated in the vertical direction. The drive mechanism 34a is provided with a drive rotation shaft 35 in which the first support portion 30a is fixed to one end side, and the movement and rotation of the drive rotation shaft 35 are emptied as a drive source by the control device 6. It is controlled by the control of the pressure cylinder and motor. By controlling the drive mechanism 34a by the control device 6, the first support portion 30a is in an initial state in which the upper surface and the lower surface of the processed material 100 are oriented in the vertical direction in the axial view (FIG. 3 (A)). It is possible to change from the measurement state (state of FIG. 3C) rotated by 45 degrees.

The drive mechanism 34b is a mechanism for operating the second support portion 30b so that the operation of the first support portion 30a by the drive mechanism 34a and the second support portion 30b overlap in the axial direction, and is configured in the same manner as the drive mechanism 34a. Has been done. By controlling the drive mechanism 34b by the control device 6, the second support portion 30b changes the orientation of the processed material 100 in the axial view from the initial state (state of FIG. 3A) to the measurement state (of FIG. 3C). It is configured so that it can be changed to a state).

The control device 6 stores a program for controlling the operation of the power source of the drive unit for operating the first support unit 30a and the second support unit 30b, and controls the operation of the position detection devices S1, S2a, S2b. The program is remembered. Further, in the control device 6, the measurement result of the surface position output from the position detection devices S1, S2a, S2b, the direction of the curvature detected based on the measurement result, the magnitude of the curvature, and the like are processed. It is stored as deformation correspondence information corresponding to the deformation state of the material 100. Further, the control device 6 performs an calculation for determining the direction of curvature, an operation for determining the magnitude of the curvature, and the like based on the measurement results output from the position detection devices S1, S2a, and S2b. The program is remembered. The contents of control of the operation of the first support portion 30a and the second support portion 30b by the control device 6 and the control of the measurement results of the position detection devices S1, S2a, S2b will be described later.

Next, specific operation examples of the first support portion 30a and the second support portion 30b operated by the drive mechanisms 34a and 34b will be described mainly with reference to FIG. FIG. 3 is a schematic view for explaining the operation of the support portions 30a and 30b of the processed material curvature detecting device 4, and operates so that the orientation of the processed material 100 can be changed by the first support portion 30a in the axial view. Each state of the process is schematically shown. The second support portion 30b operates so as to overlap with the first support portion 30a, and illustration and description of the configuration relating to the operation of the second support portion 30b will be omitted.

When the curvature of the processed material 100 is measured by the processed material curvature detecting device 4, the processed material 100 to be measured is detected by the moving unit 14 (see FIG. 1) from the supply unit 11 (see FIG. 1). Moved to device 4. As shown in FIG. 3A, the processed material curvature detecting device 4 is provided with a mounting table (not shown) capable of supporting the lower side of the processed material 100 so that the upper surface and the lower surface face in the vertical direction. Then, the processed material 100 is temporarily placed on the mounting surface PS of the mounting table. This mounting table is provided, for example, at a plurality of locations displaced in the longitudinal direction of the processed material 100 with respect to the positions where the first support portion 30a, the second support portion 30b, and the position detection devices S1, S2a, and S2b are arranged. It is configured by providing a support portion that supports the lower side of the processed material 100.

The mounting table of the processed material curvature detection device 4 may be configured to only support the lower side of the processed material 100, or may include a plurality of rollers arranged at intervals in the longitudinal direction of the processed material 100. , A drive mechanism for driving the rollers may be provided, and the processed material 100 may be configured to include a transfer mechanism capable of moving in the longitudinal direction. In this case, the transfer mechanism is used from the supply unit 11. The processed material 100 may be moved to the position in the initial state where the curvature measurement is executed, or the processed material 100 after the curvature measurement may be moved to another position close to the standby portion 12 or the retracting portion 13. May be good.

In the initial state, in the first support portion 30a, the lower right support portion 31R (specifically, the tangent plane between the lower right protruding portion 32R and the upper right protruding portion 33R) is substantially parallel to the mounting surface PS. The lower left support portion 31L (specifically, the tangent plane between the lower left protrusion 32L and the upper left protrusion 33L) takes an initial posture that is substantially perpendicular to the mounting surface PS. After the processed material 100 is arranged in the initial state, as shown by an arrow in FIG. 3A, the center position of the drive rotation shaft 35 corresponds to the center position (initial position) corresponding to the initial state. SP), while moving to the horizontal side where the processed material 100 is arranged, the first support portion 30a is rotated to the direction side to be rotated to one side.

Here, the moving direction of the drive rotation shaft 35 in the horizontal direction (right direction in FIG. 3A) is the center of gravity C of the processed material 100 due to the rotation in the direction in which the first support portion 30a is rotated. Is set in the direction opposite to the direction in which it will move (leftward). Therefore, the position of the center of gravity C of the processed material 100 is less likely to shift in the horizontal direction, and the center of gravity C of the processed material 100 can be easily moved only to the vertical direction side by moving the first support portion 30a. The amount of movement to the horizontal direction is preferably such that the position of the center of gravity C of the processed material 100 hardly moves to the horizontal side. For example, the amount of movement to the horizontal side in the axial view of the processed material 100 in the initial state is The width is often about 1/10 or less, and preferably about 1/20 or less. For example, when the length of one side is 100 mm and the cross-sectional shape is square. It is preferably 10 mm or less.

The direction of rotation of the first support portion 30a is the direction in which one end side (right side of FIG. 3A) of the surface facing the lower side of the processed material 100 rises, thereby causing the first support portion 30a to rotate. The position and the posture change, and as shown in FIG. 3B, the processed material 100 rotates in the axial view. When the processed material 100 is rotated, the lower right support portion 31R (specifically, the lower right protruding portion 32R and the upper right protruding portion 33R) moves upward to include the upward component in the vertical direction. , The direction of the processed material 100 is changed by raising one end side (right side of FIG. 3B) of the lower surface (side surface 100R) of the processed material 100 more than the opposite side (left side of FIG. 3B) in the initial state. Let me.

When the amount of rotation of the drive rotation shaft 35 reaches 45 degrees from the initial state, the processed material 100 is symmetrically supported by the first support portion 30a as shown in FIG. 3C. In this measurement state, the center position of the drive rotation shaft 35 is located vertically below the center (center of gravity C) of the processed material 100, and the operation of the drive rotation shaft 35 is stopped. At this time, in the first support portion 30a, the tangent plane between the lower left protruding portion 32L and the upper left protruding portion 33L and the tangent plane between the lower right protruding portion 32R and the upper right protruding portion 33R are on the mounting surface PS. On the other hand, both are inclined by 45 degrees. Therefore, the center of gravity C of the processed material 100 can be lowered in a well-balanced manner in the axial direction to make it easier to approach a stable state, and the deviation of the supported state of the processed material 100 in the measured state can be minimized. it can.

After the measurement state is reached, the position of the surface of the lower right side surface 100R and the position of the surface of the lower left side surface 100L are detected by the position detection devices S1, S2a, S2b, and the detection result is sent to the control device 6. Entered. By inputting the detection result, the bending direction and the bending magnitude of the processed material 100 are detected by the control device 6, and the bending measurement is executed. The method of using the result of the curvature measurement by the control device 6 will be described later.

After the curvature measurement is performed, the processed material 100 is rotated from a state in which the two side surfaces 100L and 100R facing downward are tilted obliquely, and one of the side surfaces faces vertically downward. The direction of rotation is a direction of returning to the direction of the processed material 100 in the initial state and a direction of further rotating the processed material 100 so as to be a direction rotated by 90 degrees from the direction of the processed material 100 in the initial state. There is. The control device 6 is operated in a direction of returning to the direction of the processed material 100 in the initial state, and in a direction of rotating so as to be rotated 90 degrees from the direction of the processed material 100 in the initial state. Both the operation control and the operation control may be provided, and the rotation direction may be switched and controlled as necessary, or the rotation direction may be controlled to rotate only in one of them.

When control is performed by the control device 6 in the direction of returning to the direction of the processed material 100 in the initial state, the drive rotation shaft 35 is indicated by the solid arrow in FIG. 3C after the curvature measurement is executed. As shown, control is performed so that the drive rotation shaft 35 rotates in the return direction (clockwise in FIG. 3C) while moving in the return direction (left side in FIG. 3C). The device 6 controls the operation of the drive rotation shaft 35. As a result, the position and posture of the first support portion 30a return to the initial state shown in FIG. 3A. After that, the machined material 100 for which the curvature measurement has been executed moves to the standby unit 12 or the retracting unit 13 (see FIG. 1) under the control of the control device 6 for the operation of the moving unit 14.

When the processed material 100 is further rotated so as to be rotated 90 degrees from the direction of the processed material 100 in the initial state, the direction indicated by the arrow of the alternate long and short dash line in FIGS. 3 (C) to 3 (E). The position and orientation of the first support portion 30a are controlled by the control device 6. In this case, the control device 6 controls the operation of the drive rotation shaft 35, and the drive rotation shaft 35 is driven while further moving in the direction of transition from the initial state to the measurement state (right side in FIG. 3C). The rotation shaft 35 is further rotated in the direction of transition from the initial state to the measurement state (counterclockwise in FIG. 3C). Due to the movement and rotation of the drive rotation shaft 35, as shown in FIG. 3D, the drive rotation shaft 35 is in a state of being rotated 90 degrees from the initial state, and the orientation of the processed material 100 is also 90 from the initial state. The orientation is rotated by a right angle.

After the orientation of the work piece 100 is changed, the drive rotation shaft 35 is moved downward to move the first support portion 30a downward, and then, as shown in FIG. 3 (E), the drive rotation shaft While moving 35 to one side (left side of FIG. 3 (E)) so as to approach the position in the initial state, rotate it to one side (clockwise in FIG. 3 (E)). As a result, the first support portion 30a can be moved under the processed material 100 so that the processed material 100 and the first support portion 30a do not come into contact with each other.

When the center position of the drive rotation shaft 35 reaches the lower side in the vertical direction of the initial position SP, the first support portion 30a is moved to the initial state shown in FIG. 3A by moving the drive rotation shaft 35 upward. Return. As a result, the processed material 100 can be oriented 90 degrees with respect to the posture in the initial state. By repeating the operations shown in FIGS. 3A to 3E, the operations of the first support portion 30a and the second support portion 30b are utilized to change the processed material 100 to 270 degrees even at 180 degrees from the initial state. However, it can be rotated, and the processed material 100 can be arranged so that the side surface faces a predetermined direction on any side surface.

Here, the processed material curvature detecting device 4 is configured so that the relative position between the first support portion 30a and the processed material 100 changes in the process of shifting the first support portion 30a from the initial state to the measurement state. There is. Specifically, in the initial state in which the processed material 100 is carried into the processed material curvature detecting device 4, as shown in FIG. 3A, the lower left support portion 31L and the lower right side of the first support portion 30a. The support portion 31R is arranged at a position where it does not come into contact with the processed material 100.

Further, in the process of shifting the first support portion 30a from the initial state to the measurement state, as shown in FIG. 3B, the lower right support portion 31R abuts on the processed material 100, while the lower left support portion 31R abuts. The 31L goes through a non-contact state (one-side contact state), and then the processed material 100 also contacts the lower left support portion 31L to support the processed material 100. As a result, the processed material 100 can be slid and dropped between the lower left support portion 31L and the lower right support portion 31R. In this case, the processed material 100 is in a measured state as compared with the case where the lower left support portion 31L and the lower right support portion 31R come into contact with the processed material 100 in an irregular order or at the same time. It is possible to improve the accuracy of arranging the center of gravity C so as to be located at the lowest position, and it is possible to measure the curvature with high accuracy.

In the process from the initial state to the measurement state, the period during which the lower left support portion 31L does not come into contact with the processed material 100 is preferably set to a certain angle or more, for example, the processed material 100 is at least 5 degrees or more. It is preferable that the lower left support portion 31L does not come into contact with the processed material 100 until it rotates, whereby the processed material 100 is surely provided with the momentum when the processed material 100 is slid down. It is possible to make it easier to bring it into contact with 31L. The angle is preferably about 5% or more (for example, 3 degrees or more) of the angle from the initial state to the measurement state (for example, 45 degrees), and is about 10% or more (for example, 5 degrees or more). Is preferable.

Further, in the process from the initial state to the measurement state, the period during which the lower left support portion 31L does not come into contact with the processed material 100 is preferably set to be at least a certain angle, for example, the processed material 100 is at least. When it is rotated by more than 10 degrees, it is preferable to configure the lower left support portion 31L so as to surely contact the processed material 100, whereby the momentum when the processed material 100 is slid down is excessive and the processing is performed. It is possible to avoid a situation in which the surface of the material 100 is damaged or the processed material 100 is not depressed due to the variation in the roughness of the surface of the processed material 100. The angle is preferably about 40% or less (for example, 15 degrees or less) of the angle from the initial state to the measurement state (for example, 45 degrees), and is about 30% or less (for example, 10 degrees or less). Is preferable.

During the period from the initial state to the measurement state, the lower left support portion 31L does not come into contact with the processed material 100, the contact portion between the lower left support portion 31L and the lower right support portion 31R and the processed material 100. The material and the acceleration of the operation of the first support portion 30a by the drive mechanism 34a can be adjusted and changed. For example, a member made of a material different from that of the main body portion may be attached to the contact portion of the lower left support portion 31L and the lower right support portion 31R with the processed material 100 to change the contact portion from metal to resin. The length of the non-contact period can be changed by performing surface treatment or changing the acceleration of the operation of the first support portion 30a by the drive mechanism 34a.

Further, in the initial state, at least one of the lower left support portion 31L and the lower right support portion 31R may be in contact with the processed material 100. For example, the first support so that the support surface of the processed material 100 by the lower right support portion 31R (the tangent plane between the lower right protruding portion 32R and the upper right protruding portion 33R) is substantially the same as the mounting surface PS. The vertical position of the portion 30a and the amount of protrusion of the lower right protruding portion 32R and the upper right protruding portion 33R may be set.

Further, in the initial state, the processed material 100 does not necessarily have to be placed on the mounting table, and the processed material 100 may be supported by at least one of the first support portion 30a and the second support portion 30b. In this case, the mounting table may be omitted.

Further, a mechanism may be provided to facilitate the downward movement of the processed material 100 in the measurement state supported by the lower left support portion 31L and the lower right support portion 31R. For example, the protruding portions 32L, 32R, 33L may be provided. , 33R may be formed by a roller that rotates so that the processed material 100 can easily move downward in the measured state.

Further, it is preferable to give vibration to the processed material 100 at the stage of the measurement state. For example, the first support portion 30a may be suddenly stopped at the stage of being in the measurement state so that the processed material 100 is vibrated. Specifically, as a mechanism for rotating the first support portion 30a in the processed material curvature detection device 4 and the first support portion 30a such as the drive rotation shaft 35, a cylinder that operates pneumatically is provided, and this cylinder can be used. The drive mechanism 34a may be configured so that the position in contact with the stopper with the maximum stroke is set as the measurement state.

Further, if the first support portion 30a and the second support portion 30b have a configuration in which at least a part of the processed material 100 can be moved upward or downward in the process leading to the measurement state, the first support portion 30a and the second support portion 30b pass through another route. It may be configured to move. For example, the lower left support portion 31L and the lower right support portion 31R are composed of separate members, and the lower left support portion 31L is fixedly arranged at the angle shown in FIG. 3C to support the lower right side. The work material 100 may be supported by the first support portion 30a and the second support portion 30b by shifting from the initial state to the measurement state by rotating only the portion 31R.

Further, the lower right side support portion 31R does not necessarily have to change the direction of the processed material 100 by the rotational operation. For example, the lower right side protruding portion 32R and the upper right side protruding portion 33R are respectively on the vertical direction side. The processed material 100 may be rotated in a direction corresponding to the measurement state from the initial state by moving the upper right side protrusion 33R significantly upward from the lower right side protrusion 32R.

Further, the drive rotation shaft 35 is configured to perform an operation including movement and rotation when shifting from the initial state to the measurement state, but simply by rotating the drive rotation shaft 35 from the initial state to the measurement state. The first support portion 30a and the second support portion 30b may be rotated to be in the measurement state.

Further, when shifting from the initial state to the measurement state, either the lower left support portion 31L or the lower right support portion 31R moves not to the upper side but to the lower side, and the orientation of the processed material 100 is changed. It may be changed. For example, in the initial state of FIG. 3A, the processed material 100 is directly supported by the first support portion 30a, and from the state of being supported by the first support portion 30a, the lower right. The first support portion 30a may be rotated counterclockwise by approximately 45 degrees around the right side portion corresponding to the tip portion of the side support portion 31R to be in the measurement state.

Further, the first support portion 30a and the second support portion 30b may be configured to move without changing the posture as the measurement state, and are lowered toward the processed material 100 supported by the mounting surface PS. From the side, the first support portion 30a and the second support portion 30b may move ascendingly to support the processed material 100 while maintaining the posture in the measured state.

Further, in the measurement state in which the processed material 100 is supported by the first support portion 30a and the second support portion 30b, the first support portion 30a and the second support portion 30b can be moved along the longitudinal direction of the processed material 100. The position of the work material 100 in the measurement state can be changed with respect to the position detection devices S1, S2a, S2b, S3a, S3b, S4a, S4b (see FIG. 2), and a plurality of side surfaces 100R and 100L of the work material 100 can be changed. The position of the surface of the portion may be detected by at least a part of the position detecting devices S1, S2a, S2b, S3a, S3b, S4a, S4b.

Next, the detection of the direction and the magnitude of the curvature in the processed material curvature detection device 4 will be described with reference to FIG. FIG. 4 is a cross-sectional view schematically showing the result of bending measurement of the processed materials 100 having different bending directions, and shows a case where the cross section at the position where the deviation amount is measured by the position detecting device S1 is viewed from the front side. The state in which the second support portion 30b is visible on the back side is shown.

4 (A) and 4 (B) show that the bending direction of the processed material 100 is orthogonal to one side of the contour of the processed material 100 on the cut surface perpendicular to the longitudinal direction of the processed material 100 (on one side surface). It is sectional drawing which shows the measurement state in the case of (vertical direction). 4 (C) and 4 (D) are measurements in the case where the bending direction of the processed material 100 is a direction between the orthogonal direction of one side of the contour and the diagonal direction along the diagonal line of the contour. It is sectional drawing which shows the state. 4 (E) and 4 (F) are cross-sectional views showing a measurement state in the case where the contour is in the diagonal direction. In each of the drawings from FIGS. 4 (A) to 4 (F), the direction of curvature is indicated by the direction of the arrow from the center position (position of the center of gravity C) of the processed material 100.

The two side surfaces 100L and 100R of the processed material 100 supported by the first support portion 30a and the second support portion 30b in the measurement state are from the laser displacement meters 41L and 41R (see FIG. 2) constituting the position detection device S1. The inspection light is irradiated along the optical paths VL and VR substantially perpendicular to the side surfaces 100L and 100R, and the detection result corresponding to the position of the surface of each side surface 100L and 100R is output. As a result, the laser displacement meter 41L can measure the amount of deviation ZL on the lower left side along the optical path VL, and the laser displacement meter 41R can measure the amount of deviation ZR on the lower right side along the optical path VR.

In addition, in FIGS. 4 (A) to 4 (F), the deviation amounts ZL and ZR as the measurement results are given different alphabets corresponding to each figure, and are exemplified as the deviation amounts ZLb to ZLf and ZRa to ZRf. ing. Further, the measurement results by the laser displacement meters 41L and 41R take a positive value when the distance along the optical path VR to the side surfaces 100L and 100R is farther than the distance to the reference cross section CS, and take a negative value when the distance is close. The case where it is set to take is illustrated.

First, when the processed material 100 matches the ideal shape, the surface of the intermediate portion where the position detection device S1 is provided with respect to both ends supported by the first support portion 30a and the second support portion 30b. The position of is coincided with the distance to the reference cross section CS, and the deviation amounts ZL and ZR are both 0. By inputting this measurement result to the control device 6, it can be identified in the control device 6 that the processed material 100 has no curvature, no magnitude of curvature, and no direction of curvature.

As shown in FIG. 4A, when the bending direction of the processed material 100 is the direction perpendicular to the side surface 100R facing the lower right side, the side surface 100R is the lower right side support portion of the second support portion 30b. It is arranged so as to overlap a part of 31R (lower right protruding portion 32R and upper right protruding portion 33R). In this case, the position of the cross section KS of the processed material 100 measured by the position detecting device S1 is along the direction of the curvature with respect to the position of the reference cross section CS corresponding to the cross section of the processed material 100'of the ideal shape. That is, the laser displacement meter 41R shifts to the lower right side along the optical path VR. At this time, the displacement amount ZR measured by the laser displacement meter 41R becomes a negative value (−ZRa), and the displacement amount ZL (ZLb) measured by the laser displacement meter 41L becomes 0. From this measurement result, it can be identified that the bending direction of the processed material 100 is on the lower right side in the axial direction, and that the curvature of the processed material 100 corresponds to the absolute value of the deviation amount ZRa. it can.

Even when the bending direction of the processed material 100 is perpendicular to the other side surface, the magnitude of the bending and the bending direction can be discriminated in the same manner as in the case of being perpendicular to the side surface 100R described above. For example, as shown in FIG. 4B, when the direction is perpendicular to the side surface 100L facing the lower left side, the bending direction of the processed material 100 is that the deviation amount ZR is 0 and the deviation amount ZL. Is a positive value, it can be identified that it is on the upper right side, and it can be identified that the magnitude of the curvature of the processed material 100 corresponds to the absolute value of the deviation amount ZLb.

FIGS. 4 (C) to 4 (F) illustrate the case where the bending direction of the processed material 100 is different from the direction of the side surfaces 100L and 100R. In this case, the bending direction of the processed material 100 can be identified by the ratio of the magnitude of the deviation amount ZR and the deviation amount ZL, and is shown in FIGS. 4 (E) and 4 (F), for example. As described above, when the deviation amount ZR and the deviation amount ZL match, the direction is inclined by approximately 45 degrees from the directions of the side surfaces 100L and 100R (the direction facing the corner portion in the square cross section KS). Can be identified.

Further, as shown in FIGS. 4C and 4D, when the deviation amount ZR and the deviation amount ZL are different, the bending direction of the processed material 100 is the direction in which the side surfaces 100L and 100R face and their directions. This is a case where the direction is between the direction tilted by about 45 degrees from the direction. Even in this case, the bending direction and the bending magnitude of the processed material 100 can be discriminated by the ratio of the magnitudes of the deviation amount ZR and the deviation amount ZL. That is, as the direction of curvature, the angle in the oblique direction (inclination with respect to the side surfaces 100L and 100R) between the corner portion of the square cross section KS and the direction perpendicular to the side surfaces 100L and 100R can be identified, and the amount of deviation can be identified. The specific direction can be identified depending on whether the ZR and the deviation amount ZL have a positive value or a negative value.

As described above, the bending direction of the processed material 100 can be identified by the ratio of the magnitude of the deviation amount ZL and the deviation amount ZR and whether it is a positive value or a negative value. Further, the magnitude of the curvature of the processed material 100 is obtained by adding the length obtained by combining the deviation amount ZL and the deviation amount ZR (specifically, the square of the deviation amount ZL and the square of the deviation amount ZR). It can be estimated by the size calculated by the square root of the added value).

As the deviation amount ZR and the deviation amount ZL, not only the position detection device S1 but also at least one value of the position detection devices S2a, S2b, S3a, S3b, S4a, and S4b is used, and the deviation amount ZR and the deviation amount ZL are used. May be calculated. For example, when calculating the direction of curvature and the magnitude of curvature using the values of the position detection device S1 and the position detection devices S3a and S3b, the measurement results of the position detection device S1 are deviated by the amount of deviation ZL1, ZR1 and the position detection device. Assuming that the measurement results of S3a and S3b are the deviation amounts ZL3a, ZR3a, ZL3b, ZR3b, the deviation amount ZL can be calculated by "ZL1- (ZL3a + ZL3b) / 2", and the deviation amount ZR is "ZR1- (ZR3a + ZR3b)". ) / 2 ”. The calculation for this calculation may be executed by providing a calculation unit in the machined material curvature detecting device 4, or the processing material bending detecting device 4 outputs the measurement result to the control device 6, and the control device 6 performs the calculation. It may be a configuration to be performed.

As described above, according to the processed material curvature detecting device 4, the processed material 100 is in a state of being supported by the first support portion 30a and the second support portion 30b, and then the position detecting device S1 first supports the processed material 100. The positions of two surfaces separated in the circumferential direction in the axial view from the central portion of the processed material 100 located between the support portion 30a and the second support portion 30b are detected. When the processed material 100 matches the ideal shape, the position of the surface of the intermediate portion where the position detection device S1 is provided with respect to both ends supported by the first support portion 30a and the second support portion 30b. Is detected by the position detection device S1, and a detection result corresponding to the result that the processed material 100 has no curvature, no magnitude of curvature, and no direction of curvature is output.

On the other hand, when the processed material 100 has a shape including a certain degree of curvature with respect to the ideal shape, the position detecting device with respect to both ends supported by the first support portion 30a and the second support portion 30b. The position of the surface of the intermediate portion provided with S1 is different from the position of the surface detected by the position detecting device S1 in the ideal shape, and is biased toward the bending direction side. The position detection device S1 outputs a detection result different from the detection result in the ideal shape according to the deviation of the position of the surface. When the output detection result is input to the control device 6, the control device 6 can discriminate between the bending direction and the bending magnitude of the processed material 100.

Further, the first lower left support portion (lower left support portion 31L) and the first lower right support portion (lower right support portion 31R) in the first support portion 30a can be operated in the vertical direction by the drive mechanism 34a. It is possible, and the second lower left side support part (lower left side support part 31L) and the second lower right side support part (lower right side support part 31R) in the second support part 30b are operated in the vertical direction by the drive mechanism 34b. It is possible. When the first support portion 30a and the second support portion 30b are operated in the vertical direction by the drive mechanisms 34a and 34b and the workpiece 100 is rotated in the axial view, the center of gravity of the workpiece 100 moves in the vertical direction. After the movement, the first support portion 30a and the second support portion 30b are stationary, and the processed material 100 is in a measurement state supported by the lower left support portion 31L and the lower right support portion 31R. By supporting the lower side of the processed material 100 while making it easy for the center of gravity of the processed material 100 to move, the center of gravity of the processed material 100 moves downward due to the weight of the processed material 100 in the measurement state to be in a stable state. It is easy to approach, and the center of gravity of the processed material 100 is likely to be located at the maximum lower position.

A large amount manufactured aiming at an ideal shape by detecting the position of the surface of the processed material 100 with the position detecting device S1 after the center of gravity of the processed material 100 is moved downward to the maximum to stabilize the state. The processed material 100 can be easily brought close to a state in which the processed material 100 is supported at an appropriate position in the same manner by the first support portion 30a and the second support portion 30b. When the processed material 100 is supported at an appropriate position, when the processed material 100 to be measured that detects the position of the surface with respect to the ideal shape includes a curvature, the direction of the curvature and the magnitude of the curvature Correspondingly, a specific deviation occurs in the position of the surface of the processed material 100 detected by the position detecting device S1. Therefore, by detecting the position of the surface of the processed material with the position detecting device S1 after the processed material 100 is supported at an appropriate position, the direction of bending with respect to the processed material 100 and the magnitude of the curvature can be determined. Can be easily detected accurately.

As described above, according to the processed material curvature detecting device 4 of the precut processing device 1, the processed material 100 is supported by the first support portion 30a and the second support portion 30b, and the position of the surface is supported by the position detecting device S1. By detecting the above, it is possible to detect the direction of the curvature and the magnitude of the curvature as the bending condition of the processed material 100. Therefore, when the processed material 100 includes a curve, the state of the curve can be easily detected in a short time.

Further, the drive mechanisms 34a and 34b can operate the first support portion 30a and the second support portion 30b to bring the processed material 100 closer to a state of being supported at an appropriate position. Therefore, when the position of the surface of the processed material 100 is detected by the position detecting device S1, the direction of bending and the magnitude of bending can be easily detected. Therefore, in the case of manufacturing the structural member, it is possible to easily detect the bending condition and to easily perform the processing according to the bending condition.

Further, in the processed material curvature detecting device 4, the first support portion 30a and the second supporting portion 30b are the surfaces of the processed material 100 in a measurement state in which the position of the surface of the processed material 100 is detected by the position detecting device S1. Of these, the lower sides of the two side surfaces 100L and 100R, which are planar and face substantially orthogonal directions in the longitudinal direction of the processed material 100, are centered in the horizontal direction where the center (center of gravity C) of the processed material 100 is located. Support in a tilted state so that the side is low. Therefore, the processed material 100 easily slides down to the center side where the center of gravity C is located along the flat side surfaces 100L and 100R, and it is easy to use the own weight of the processed material 100 to make the center of gravity located at the lowest side. can do.

Further, the drive mechanisms 34a and 34b of the processed material curvature detection device 4 are configured so that the processed material 100 supported by the first support portion 30a and the second support portion 30b can be rotated in the axial view. , The processed material curvature detection device 4 can be used as the processed material rotating device 5. Therefore, it is possible to easily add a function capable of detecting the bending state of the processed material 100 to the conventional precut processing apparatus having a wood rotation function at low cost.

Next, with reference to FIGS. 5 to 7, a configuration in which the structural member is manufactured in the precut processing device 1 by using the result of the curvature measurement detected by the processed material curvature detection device 4 will be described.

FIG. 5 is an explanatory diagram showing control for manufacturing a structural member from a processed material whose curvature is measured by a control device 6. FIG. 6 is a plan view schematically showing an example of a skeleton structure made up of various structural members in a building. FIG. 7A is an explanatory diagram showing the classification of the bending direction and size set based on the arrangement information and the bending direction and size detected by the processed material bending detection device 4, and FIG. 7A is an explanatory view showing the classification. B) is an explanatory diagram showing an example of control for matching the directions of bending.

The pre-cut processing device 1 is detected by the bending direction (hereinafter, also abbreviated as "set bending direction") set based on the arrangement information stored in the storage unit of the control device 6 and the processing material bending detection device 4. The wood processing device 2 is controlled according to the processing data stored in the storage unit of the control device 6 so as to match the bending direction (hereinafter, also abbreviated as "detection bending direction"). It is configured to include a control device for processing 100. As a specific example, the direction of bending set by the machined material rotating device 5 based on the arrangement information stored in the storage unit of the control device 6 and the direction of bending detected by the machined material bending detecting device 4 are set. The structure is such that the orientation of the processed material 100 can be changed so as to match.

In the manufacture of each structural member, the precut processing apparatus 1 processes the processed material 100 so that the set bending direction of the structural member and the detected bending direction of the processing material 100 match, so that the magnitude of the curvature is a constant value ( For example, even a processed material exceeding 0.5 mm / 3000 mm, which is a value indicated by the ratio of the magnitude of curvature to the total length of the structural member, can be used as a material for manufacturing the structural member as a long material. To. That is, the precut processing device 1 expands the usable range in consideration of not only the magnitude of the curvature but also the direction of the curvature, and also depends on the type (role) of the structural member in the building. Expand the available range while making it different.

In the storage unit of the control device 6 (see FIG. 1), as a part of the arrangement information, a structural member number different for each structural member for identifying the arrangement position of each structural member constituting the building, and the structural member Information corresponding to the type is stored. Specifically, as shown in FIG. 5, the storage unit of the control device 6 stores arrangement information corresponding to each type of structural member in association with each structural member number, and arranges the horizontal direction as the longitudinal direction. The horizontal members 101 to 106 are arranged as a type of structural member, for example, "1", and the vertical members arranged with the vertical direction as the longitudinal direction, for example, "2". Different arrangement information is stored corresponding to the longitudinal direction (arrangement direction) to be performed.

Further, in the storage unit of the control device 6 (see FIG. 1), as a part of the arrangement information, the arrangement information corresponding to the usage points further classified by type for the vertical pillar material is stored. For the corner pillars 111, 118, 120, 121 arranged in the corners of the outer contour of the building, for example, "1" and the main space (room, entrance, corridor, stairs, etc.) are separated. For the partition columns 114, 117, 119, 122, 124 to be arranged, for example, the arrangement information "2" is stored separately from the information corresponding to the orientation of the arrangement. Similarly, the window door columns 112, 113, 115, 116 for fixing the opening / closing members 131, 132 such as windows and doors, and the exposed columns 123 arranged so that at least one side surface is exposed in the main space. On the other hand, different arrangement information is assigned and stored.

Here, the arrangement information may be input to the pre-cut processing apparatus 1 as a part of the processing data and may be assigned by the CAD based on the skeleton structure drawn by the CAD, or the print contents of the input processing data may be assigned. Based on the information, it may be assigned by the control program of the control device 6 of the pre-cut processing device 1, or the operator may manually input the data to be stored in the storage unit. For example, as a part of the processing data, it is a vertical column material or a horizontal member by using a numbering (coordinate position) indicating the positions of both ends where the structural member is installed so as to indicate the arrangement position of the structural member. It may be determined whether or not it is used as arrangement information, or it may be determined that the groove is a corner column in the vertical column material based on the shape formed by one side and used as arrangement information. , A program for performing this determination may be provided in the control device 6.

In the storage unit of the control device 6, information corresponding to the direction of the wall along the horizontal member 101 or the like to be joined (for example, "1" in the east) is stored in the storage unit of the control device 6 as a part of the arrangement information. , "2" in the north, etc.) are remembered. As a result, the processed material 100 can be processed so that the bending direction of the processed material 100 coincides with the direction side along the direction of the wall. Therefore, the processed material 100 including a large curvature of a certain value or more is used. However, it is possible to prevent the problem that the surface of the wall is deformed due to the contact of the vertical column member with the member constituting the surface of the wall.

Based on the orientation of the wall and the type of vertical column member, the control device 6 sets the allowable bending direction and the amount of bending. Specifically, as shown in FIG. 6, information corresponding to only one direction is stored as the direction of the wall for each corner pillar 111, and information corresponding to only one direction is stored in the vicinity thereof as the direction that allows the protrusion due to the curvature. The arrangement information corresponding to one direction indicated by the illustrated arrow is stored as the information corresponding to the direction of the wall.

For each section pillar 114 and the like, the arrangement information corresponding to the two directions indicated by the arrows shown in the vicinity thereof is stored as information corresponding to the direction of the wall, and for each window door pillar 112 and the like, the arrows shown in the vicinity thereof are stored. The arrangement information corresponding to one direction pointed to by is stored as the information corresponding to the direction of the wall. As for the exposed column 123 as a vertical column material that is not arranged in contact with the wall, the arrangement information corresponding to the orientation of the wall is not stored as shown by the arrow, and for example, the information of "0" is stored. ..

In addition, the storage unit of the control device 6 may store information for designating the orientation of the wall for each type of constituent member in another mode. For example, the direction of the wall with respect to the corner pillar 111 is not only one direction (right side in FIG. 6) facing the other end side of the horizontal member 101, but also the direction of the joint side of the horizontal member 102 joined to the horizontal member 101. (Lower side in FIG. 6) may also be allowed.

Further, the configuration is not limited to a configuration in which the allowable wall orientation is uniquely determined for each type of structural member, and even for the same type of structural member, the allowable wall orientation is different depending on the arrangement location. It may be. For example, the storage unit of the control device 6 does not allow the wall orientation in two directions with respect to two adjacent partition columns when a plurality of partition columns 114 are arranged on the same horizontal member. The orientation of the walls of the two adjacent compartment columns may be set so that, for example, when one allows the right side, the other allows the left side.

Further, in the storage unit of the control device 6, instead of the information corresponding to the orientation of the wall for each type of the constituent member, the information corresponding to the orientation of the horizontal member 101 or the like to be joined (extracted from the arrangement in the assembly drawing). Information that can be stored) may be stored. Further, in the storage unit of the control device 6, instead of the information corresponding to the orientation of the wall, information regarding the processing shape characteristic for each type of structural member, for example, the information regarding the longitudinal direction of the width of the groove in the protruding direction view ( Information that can be extracted from the processing data) and the like may be stored. In this case, it is not necessary to store the dedicated information in the control device 6, and the machining data may be referred to.

In the storage unit of the control device 6, a program for setting the setting bending direction for each structural member or the like is stored for each structural member based on the arrangement information corresponding to each structural member. Specifically, the control unit of the control device 6 sets the set bending direction according to the program, one bending division A, four bending divisions B1 to B4, and four bending divisions Ca as shown in FIG. 7A. It is set by selecting at least one curvature division from ~ Cd. By this setting, one or a plurality of bending divisions (hereinafter, referred to as set bending divisions) selected by the control unit of the control device 6 are stored in the storage unit of the control device 6 as information for designating the set bending direction. .. However, as described below, the control unit of the control device 6 sets different setting curvature classifications for each type of structural member.

The storage unit of the control device 6 may store a program in which a plurality of curvature divisions different from the above nine curvature divisions are set and the set curvature division is determined by the combination of the plurality of curvature divisions. For example, the curvature division A may be omitted, or the curvature division may be configured by a different shape in which the magnitude of the curvature is omitted from the curvature divisions Ca to Cd in the range of 2 mm to 3 mm. Further, the storage unit of the control device 6 stores not only a program that makes the combination of the curved sections different depending on the type of the structural member, but also a program that selects the same combination for some types having different types of the structural member. For example, the same combination of curved sections may be selected for the partition column 114 and the exposed column 123.

The control unit of the control device 6 sets the set curvature division so as to allow each horizontal member 101 or the like to have a large curvature of a certain value or more with the upward direction in the vertical direction as the direction of curvature. Assuming that the side surface of the horizontal member 101 facing the back side of the paper surface as a reference (the side surface facing downward during processing) in FIG. 6, in the axial view along the central axis in the longitudinal direction of the horizontal member 101, FIG. The front side of the paper surface in the above is the upper side in the vertical direction and corresponds to the upper side in FIG. 7 (the positive value side of ZR). For example, in order to allow the horizontal member 101 to be bent upward in the vertical direction, the control unit of the control device 6 has two of the four bending sections B1 to B4 corresponding to the upper side in addition to the bending section A. Adjacent curved sections B1 and curved sections B2 are selected, and one curved section Cb corresponding to the upper side of the four curved sections Ca to Cd is selected.

By controlling this selection, the storage unit of the control device 6 stores (sets) four curvature divisions, which are the curvature division A, the curvature division B1, the curvature division B2, and the curvature division Cb, as the setting curvature divisions for the horizontal member 101. Will be done. Similarly, the control unit of the control device 6 is selected for the other horizontal members 102 and the like based on the arrangement direction of each of the curved sections A and the four curved sections B1 to B4 such as the horizontal members 101 and the like. The two adjacent curved sections and one curved section selected based on the arrangement direction of each horizontal member from the curved sections Ca to the curved section Cd are selected. By controlling this selection, the storage unit of the control device 6 stores four selected curvature divisions as the setting curvature divisions.

In a building, generally, the load is larger toward the center side in the top view, and it is easier to apply a larger load to each horizontal member 101 or the like on the center side in the longitudinal direction than at both ends, and the building is manufactured as described above. If the horizontal member 101 or the like is used, it can be deformed so that the magnitude of the curvature becomes smaller due to the load applied to the center side, and even if the horizontal member 101 or the like manufactured as described above is used, the building can be built. The structural strength of an object can be maintained. On the other hand, when a horizontal member manufactured without matching the vertical upward direction of each horizontal member 101 and the detection bending direction of the processed material 100 is adopted, the load applied to the horizontal member is applied. As a result, it is deformed so that the magnitude of the curvature is further increased, and there is a possibility that various vertical pillar members joined to the horizontal member cannot be stably supported. For this reason, as the set curvature division for each horizontal member 101, not only the curvature division A but also the two adjacent curvature divisions and the curvature divisions Ca to Cd corresponding to the upward direction in the vertical direction among the curvature divisions B1 to B4. By selecting one curve category corresponding to the vertical direction upward curve, the magnitude of the vertical direction upward curve is increased to a predetermined allowable range (for example, the curve category B1) exceeding the above-mentioned constant value (curve category A). , Curved section B2 and curved section Cb) are allowed. Further, even in the direction orthogonal to the vertical direction, a predetermined allowable range exceeding the above-mentioned constant value (for example, curved division B1 and curved division B2) is allowed, but each horizontal member 101 or the like is allowed. In order not to project more than a predetermined amount of protrusion in the vertical direction of the surface of the wall formed along the above, the selection from the curved categories B1 to B4 is limited to the two adjacent curved sections, and from the curved sections Ca to Cd. Is limited to one curvature category, and the curvature category P and the curvature category Q are not selected, so that the value range is smaller than the permissible range in the vertical direction.

Further, the control unit of the control device 6 is in the direction indicated by the arrow shown in the vicinity of each window door pillar 112 or the like in FIG. 6 with respect to each window door pillar 112 or the like, and is the horizontal member 101 or the like to be joined. Of the walls formed along the above, the set curvature division is set so that even those that are curved in the direction of the wall on the side where the opening / closing member 131 or the like is formed are allowed. For example, the control unit of the control device 6 specifies the direction of the wall of the window door pillar 112 in one direction on the right side as shown in FIG. 6, so that the curved division A is as shown in FIG. 7 (A). In addition, of the four curvature divisions B1 to B4, the two curvature divisions B1 and the curvature division B4 corresponding to the right side are selected as a part of the set curvature divisions. Further, one of the four curvature divisions Ca to Cd corresponding to the right side is selected as a part of the set curvature division. By this selection, the storage unit of the control device 6 stores four divisions A, curvature divisions B1 to B4, and curvature division Ca as setting curvature divisions. Similarly, for the other window door pillars 112 and the like, the control unit of the control device 6 has two adjacent curved sections among the four curved sections B1 to B4 according to the direction of the wall, in addition to the curved section A. And one of the curved divisions Ca to Cd according to the direction of the wall is selected. By controlling this selection, the storage unit of the control device 6 stores four selected curvature divisions as the setting curvature divisions.

The left and right ends of the opening / closing member 131, etc. are fixed by two window door pillars 112, 113, etc., and the upper and lower ends thereof are lintel members laid horizontally over the two window door pillars 112, 113, etc. Fixed by (not shown). At this time, even if the window door columns 112, 113 and the like are curved so as to project toward the opening / closing member 131 and the like, both end portions of the lintel material are inserted into the notch grooves 112b and 113b of the window door columns 112 and 113. As a result, the lintel material and the opening / closing member 131 can be stably fixed to the window door columns 112 and 113.

On the other hand, when the window door columns 112, 113 and the like are curved so as to project to the opposite side of the opening / closing member 131, there is a possibility that the lintel material and the opening / closing member 131 cannot be stably fixed. .. Therefore, as the set curvature division for each window door pillar 112 or the like, two adjacent curvature divisions among the curvature divisions B1 to B4 and one curvature division among the curvature divisions Ca to Cd are selected. By controlling this selection, for each window door pillar 112 or the like, of the directions of the two walls formed along the horizontal member 101 or the like to be joined, the wall on the side where the opening / closing member 131 or the like is formed. The magnitude with respect to the bending of the direction is allowed up to a predetermined allowable range (for example, bending section B1, bending section B4, and bending section Ca) exceeding the above-mentioned constant value (curving section A).

In addition, the direction (direction perpendicular to the surface of the wall) perpendicular to the continuous direction (direction of the arrow in FIG. 6) of the walls (outer wall, inner wall) attached to the outside and inside of the window door pillar 112 or the like is also obtained. , The size of the curvature is allowed up to a predetermined allowable range (for example, the curvature division B1 and the curvature division B4) exceeding the above-mentioned constant value, but the window door pillar is on the side perpendicular to the surface of the wall. In order to prevent a part of the 112 and the like from protruding, the selection from the curvature divisions Ca to Cd is limited to one curvature division, and the curvature division P and the curvature division Q are not selected. Selection is controlled. As a result, as the allowable range of the magnitude of the curvature, the allowable range in the direction perpendicular to the surface of the wall is kept within the range of a smaller value than the allowable range in the continuous direction of the wall.

Further, the control unit of the control device 6 is in the direction indicated by the arrow shown in the vicinity of each corner pillar 111 or the like in FIG. 6 with respect to each corner pillar 111 or the like, and is along the horizontal member 101 or the like to be joined. The set curvature division is selected so that it is allowed to be curved in the direction of the wall formed by. For example, as shown in FIG. 6, the control unit of the control device 6 specifies the direction of the wall in one direction to the right with respect to the corner pillar 111, so that as shown in the upper left table of FIG. In addition to the curved section A, the curved section B1 and the curved section B4 corresponding to the right half of the curved sections B1 to B4 are selected. Similarly for the other corner columns 118 and the like, the control unit of the control device 6 is adjacent to the curved categories B1 to B4 according to the direction of the wall in the vicinity of each corner column 118 and the like in addition to the curved category A. Select either two curved sections. By the control of this selection, the storage unit of the control device 6 stores three curvature divisions corresponding to the curvature division A and any two adjacent curvature divisions B1 to B4 as the setting curvature division.

Each corner pillar 111 or the like is provided at the end of the horizontal member 101 or the like to be joined, and the outer wall located outside the corner pillar 111 or the like is in the direction in which the horizontal member 101 is continuous with each corner pillar as the center. , Continuous in the direction in which another horizontal member 102 is arranged. In this case, as the setting curvature division for each corner column 111 or the like, two adjacent curvature divisions along the direction in which the horizontal member 101 to be joined is continuous are selected from the curvature divisions B1 to B4. By controlling this selection, the processed material 100 including a large curvature along the direction of the continuous wall along the horizontal member 101 or the like to be joined is set to the above-mentioned constant value (for each corner column 111 or the like). It becomes possible to use up to a predetermined allowable range (for example, bending section B1 and bending section B4) exceeding the bending section A). Since each corner column 111 greatly contributes to the structural strength of the building as compared with other vertical column materials, not only the curved category P and the curved category Q but also the curved categories Ca to Cd should not be selected. It is preferable to do so.

Further, the control unit of the control device 6 is in the direction indicated by the arrow shown in the vicinity of each section pillar 114 or the like in FIG. 6 with respect to each section pillar 114 or the like, and is the horizontal member 101 to be joined. The curvature division is set so as to allow a large curvature of a certain value or more with one direction from one end toward the other end along the longitudinal direction as the direction of curvature. For example, the control unit of the control device 6 specifies the direction of the wall of the partition pillar 117 in two directions, the upper side and the lower side, as shown by the arrow shown in the vicinity of the division pillar 117 in FIG. , In addition to the curvature division A, two curvature divisions B1 and B2 corresponding to the upper side and two curvature divisions B3 and B4 corresponding to the lower side are selected from the four curvature divisions B1 to B4. .. Further, of the four curvature divisions Ca to Cd, one curvature division Cb corresponding to the upper side and one curvature division Cd corresponding to the lower side are selected. As a result, in the storage unit of the control device 6, four divisions A, curvature divisions B1 to B4, and curvature divisions Cb and Cd are stored as setting curvature divisions. Similarly, for the other section columns 117 and the like, the control unit of the control device 6 has the four curved sections B1 to B4 and the curved sections Ca to Cd in the continuous direction of the wall in addition to the curved section A. The curvature division corresponding to the two directions of curvature along the line, that is, the combination of the curvature division Ca and the curvature division Cc, or the combination of the curvature division Cb and the curvature division Cd is selected. By controlling this selection, seven selected curvature divisions are stored in the storage unit of the control device 6 as the setting curvature divisions.

Further, the control unit of the control device 6 selects only the bending category A for the exposed column 123 as an example of the column in which the allowable range of the bending size is set to be the smallest among the vertical column members. As shown in FIG. 6, unlike other structural members, an arrow is not shown in the vicinity of the exposed column 123, and the column is illustrated as a column in which no wall is provided on the surface side. This type of column may be placed in a position that is directly visible to the user of the building without going through the wall, and the user may be concerned about whether it is a straight column. Therefore, only the curvature category A that is curved only below a certain level is selected. By controlling this selection, only the curvature division A is stored in the storage unit of the control device 6. The control unit of the control device 6 selects only the curved section A in the same manner for the other exposed columns (not shown). By controlling this selection, only the curvature division A is stored in the storage unit of the control device 6 as the setting curvature division.

Next, the classification of the processed material 100 according to the direction and size of the curvature detected by the processed material curvature detecting device 4 will be described.

The storage unit of the control device 6 stores a program for determining the direction and size of the curvature of the processed material 100 based on the deviation amount ZL and the deviation amount ZR detected by the processed material curvature detecting device 4. Specifically, in the storage unit of the control device 6, the processed material 100 is stored in the bending category A, in which the range specified by the bending direction and size differs from each other depending on the combination of the deviation amount ZL and the deviation amount ZR. A program for classifying into four curvature divisions B1 to B4, four curvature divisions Ca to Cd, curvature division P, or curvature division Q is stored. The control unit of the control device 6 assigns each processed material 100 to any one of the curved sections according to the program, as shown in the table on the upper right of FIG. Based on this allocation, the assigned curvature division is stored in the storage unit of the control device 6.

Here, various types of curvature division will be described.

As shown in FIG. 7 (A), the curvature division A is defined by the magnitude of the curvature (corresponding to √ (ZL ² + ZR ² )) regardless of the direction of the curvature, and the magnitude is a constant value ( For example, it is a region of 0.5 mm) or less, and specifically, a region satisfying ZL ² + ZR ² ≤ 0.5 ² . In the control device 6, the processed material 100 belonging to the bending category A is used as a material for manufacturing all kinds of structural members, and cutting can be performed without rotating in a direction corresponding to the bending direction. Will be done.

Each of the curvature divisions B1 to B4 is a region having a larger curvature than the curvature division A. For example, in the case of the curvature division B1, ZL ² + ZR ² > 0.5 ² , 0 <ZL ≦ 1.0, Moreover, it is a region defined by 0 <ZR ≦ 1.0. Whereas the curvature division A divides the inside and outside of the range based on the magnitude of the curvature, the magnitude of the deviation amount in the two orthogonal directions (absolute value of the deviation amount ZL and the absolute value of the deviation amount ZR). ) Are both defined as regions classified according to whether or not they are within the range of the first allowable range (maximum 1.0 mm). In the control device 6, the processed material 100 belonging to any of the bending categories B1 to B4 may be rotated according to the direction of the allowable bending according to the type of the structural member, and then processed. The processed material 100 including a large curvature of a certain value or more can be used for manufacturing various structural members.

Each of the curvature divisions Ca to Cd is a region in which the amount of deviation in one of the two orthogonal directions is large with respect to the curvature divisions B1 to B4. The first region satisfying ZL ² + ZR ² ≤ 2.0 ² , ZL> 1.0 and -1.0 ≤ ZR ≤ 1.0, and 2.0 ² <ZL ² + ZR ² ≤ 3.0 ² , It is a region defined by a region including a second region satisfying −0.5 ≦ ZR ≦ 0.5 and ZL> 1.0. Specifically, the first region of the curvature division Ca is the magnitude of the deviation amount in a specific one direction (right side: the positive value side of the deviation amount ZL) with respect to the region including the curvature divisions B1 to B4. A region in which the deviation amount (absolute value of ZL) is extended to a second allowable range (maximum value 2.0 mm) larger than the first allowable range, so that the direction of curvature is aligned with the specific one direction. It is a region expanded so that the allowable range for the magnitude of curvature increases as it approaches. In the control device 6, the processed material 100 belonging to any of the bending categories Ca to Cd may be rotated in the direction of the allowable bending according to the type of the structural member, and then processed, whereby a large bending may occur. The processed material 100 containing the above can also be used for manufacturing structural members.

Further, the curvature divisions Ca to Cd are set in a third allowable range (maximum value: 3.0 mm) in which the curvature size is large with respect to the first region in which the curvature size is set to the small side in each division. It is defined to include the second area. For example, the curvature division Ca is directed to a specific direction in which the curvature is large (right side of FIG. 7A: positive value side of the deviation amount ZL) among the magnitudes of the deviation amounts perpendicular to the side surfaces 100L and 100R, respectively. Depending on whether the magnitude of the deviation amount (absolute value of the deviation amount ZL) is small or large, it is in another direction orthogonal to the specific one direction (on the vertical side in FIG. 7 (A) and on the side surface). The absolute value of the allowable deviation amount ZR is different in the direction in which the vertical deviation amount is small). That is, when the direction of curvature increases toward a specific direction, the allowable range for the amount of curvature (absolute value of the amount of deviation) on the side where the amount of deviation perpendicular to the side surface is small is set small. There is. As a result, even if the processed material 100 includes a large curvature in a specific one direction (one side surface), the large curvature can reduce inconvenience when used as a structural member, and includes a larger curvature. The processed material 100 can also be used for manufacturing structural members.

The curvature division Cb is a division in which the above specific one direction is on the upper side (positive value side of the deviation amount ZR), and the curvature division Cc is a division in which the above specific one direction is on the left side (negative of the deviation amount ZL). The value side of), and the curvature classification Cd is a classification in which the above-mentioned specific one direction is the lower side (the negative value side of the deviation amount ZR).

The curvature division Q is defined by the magnitude of the curvature, and is a region where the magnitude is larger than the third allowable range (maximum 3.0 mm), specifically, a region satisfying ZL ² + ZR ² > 3.0 ^2. is there. The processed material 100 belonging to the bending category Q is not used as a material for manufacturing a structural member which is a long material in the control device 6, but is used as a material for manufacturing a plurality of structural members (short materials), for example.

The bending category P is a region smaller than the third allowable range (maximum 3.0 mm), but is not included in any of the bending categories A, the bending categories B1 to B4, and the bending categories Ca to Cd. The processed material 100 belonging to the bending category P is not used as a material for manufacturing a structural member which is a long material in the control device 6, but is used as a material for manufacturing a short material, for example.

The numerical values in the relational expression for determining the boundaries of the curvature categories A, B1 to B4, and Ca to Cd are not limited to the above example, and the design can be changed as appropriate. A fixed value may be stored in the control program in advance for the numerical value that determines this boundary, the operator may manually set the numerical value for the control device 6, or the processing data is input. , A numerical value may be input.

Further, the portion forming an arc in the outer contour that defines the permissible range such as the curved division A and the curved division Ca to Cd may be defined by a straight line parallel to the ZL axis or the ZR axis. On the contrary, the outer contour may be defined by a circle or an arc defined by the magnitude of the curvature for the portion forming a straight line in the outer contour such as the curvature divisions B1 to B4.

Further, in each of the curved divisions B1 to B4, the region including all of them is divided vertically and horizontally to be partitioned, but the region may be partitioned by being divided by two diagonal lines. ..

Further, in each of the curvature divisions Ca to Cd, the amount of deviation in the two directions orthogonal to a specific one direction of the second region is limited to be smaller than that of the first region, but even if the configuration is not limited. Good.

Further, in each of the curvature divisions Ca to Cd, the amount of deviation in two directions orthogonal to a specific direction (absolute value of the amount of deviation ZL or the absolute value of the amount of deviation ZR) is set as a polygonal line shape at the boundary of the direction. The configuration is such that the region and the second region are changed stepwise, but the boundary in the direction may be a straight line or a curved shape, and these may be gradually changed.

Further, each of the curved divisions Ca to Cd is not limited to the configuration including the first region and the second region, and the first region and the second region are set as different divisions, and each division is assigned in the control of the allocation of the curved division. It may be configured as.

Further, the processed material 100 belonging to the curvature category Q is configured not to be used as a material for manufacturing a structural member which is a long material, but is used as a material for manufacturing a specific structural member which is a long material. May be good.

Further, in the storage unit of the control device 6, a program for determining a structural member to be manufactured from the processed material 100 is stored. The control unit of the control device 6 executes arithmetic processing according to the program, determines a structural member to be manufactured from each processed material 100 in which the direction and size of the curvature detected by the processed material curvature detecting device 4 are detected, and is determined. Information (processed material number) for associating the structural member with the processed material 100 is stored in the storage unit.

Specifically, in the storage unit of the control device 6, a program for determining the structural member to be manufactured from the processed material 100 is stored based on the detection curved category to which the processed material 100 belongs and the set curved category to which the structural member belongs. Has been done. When the processed material 100 belongs to the curved category A, the control unit of the control device 6 selects one structural member from the structural members including the curved category A in the set curved category, and selects the processed material 100 and the selected structure. Information indicating the correspondence with the member is stored in the storage unit. When the processed material 100 belongs to any of the four bending categories B1 to B4, one structural member is selected from the structural members including any of the bending categories B1 to B4 in the set bending category. When the processed material 100 belongs to any of the four bending categories Ca to Cd, one structural member is selected from the structural members including any of the bending categories B1 to B4 in the set bending category.

However, when the processed material 100 belongs to the curved category P or the curved category Q, the control unit of the control device 6 includes a horizontal member 101 or the like manufactured as a long material, a corner pillar 111 or the like, a window door pillar 112 or the like. Or, it is not assigned to the partition pillar 114 or the like or the exposed pillar 123.

In the storage unit of the control device 6, a program for matching the set bending direction of the processed material 100 with the detected bending direction of the processed material 100 is stored. Specifically, the rotation required to match the detected curvature category with any one of the set curvature categories included in the set curve category based on the detection curve category to which the processed material 100 belongs and the set curve category to which the structural member belongs. A program for determining the number of times (rotation amount) is stored. For example, as shown in FIG. 7B, the control unit of the control device 6 determines that the detected curvature category is the curvature category Cb based on the result of the curvature measurement of the processed material curvature detection device 4. When the set bending division does not include the bending division Cb and is applied to a structural member including the bending division Ca, the processed material 100 is rotated 90 degrees by 3 in order to match the bending division Cb with the bending division Ca according to the program. Decide to do it times. Based on this determination, information corresponding to the determined rotation speed is stored in the storage unit of the control device 6, and the number of times corresponding to the rotation speed is stored before the cutting process is performed by the wood processing device 2. , The control device 6 controls the machined material rotating device 5 to rotate the machined material 100.

The storage unit of the control device 6 is a program for matching the set bending direction of the processed material 100 with the detected bending direction of the processing material 100, such as the detection bending classification of the processing material 100 and the setting bending classification of the structural member. Not limited to the case of storing a program for selecting a structural member by comparison and determining the number of rotations (rotation amount), as shown in FIG. 7B, it is specified by the direction and size of curvature of the processed material 100. The structural member is determined and the number of rotations is determined by whether or not the detection point PK can be moved within the region specified by the set curvature division by a predetermined rotation, for example, one or more rotations in units of 90 degrees. You may remember the program that determines.

Here, the control device 6 controls the moving unit 14 to transport the processed material 100 whose curvature has been measured by the processed material curvature detecting device 4 to the standby unit 12 or the retracting unit 13. When executing this transfer control, the control device 6 determines a structural member to be manufactured from the transferred processed material 100 as shown in the lower left table of FIG. 6 (correspondence between the structural member number and the processed material number). The number of rotations to rotate the processed material 100 is determined prior to processing by the processing unit 21 (see FIG. 1).

In this case, in order to identify the processed material 100 for which the curvature measurement has been performed by the processed material curvature detecting device 4, and to control the rotation by the control device 6 at the rotation speed corresponding to the result of the curvature measurement. , The processed material 100 is configured to store (record) individual information (processed material individual information), and the individual information can be associated with the result of the curvature measurement and stored in the control unit of the control device 6. preferable. As this method, for example, individual IC chips may be attached to the processed material for management, or the processed material 100 may be subjected to before or after the curvature measurement is executed by the processed material curvature detecting device 4. By printing a barcode or QR code (registered trademark) and reading the printed result, the processed material 100 and the result of the curvature measurement are associated and stored in the control device 6, and the processed material corresponding to the result of the curvature measurement is stored. It is preferable to rotate 100 as necessary for processing.

The processed material 100c or the like belonging to the bending category P or the bending category Q is conveyed to the retracting unit 13 (see FIG. 1) based on the direction and size of the bending detected by the processing material curvature detecting device 4. The processing of the short material on the processed material 100c transported to the evacuation unit 13 may be executed after the processing of the long material on the processed material 100b transported to the standby unit 12, or the processing of the long material and the short material. Processing may be mixed. Further, not only when the processed materials 100b belonging to different curved sections are mixed and arranged in a row, a plurality of sections are determined between the transport portion 22 side and the opposite side, and the sections are different according to the curved sections. A configuration may be adopted in which the components are arranged so as to allow them. Further, the processed materials 100 are not limited to the configuration in which they are arranged in a single row, and may be arranged in multiple stages. Further, the evacuation unit 13 may be used as the second standby unit, and the arrangement location may be selected from the standby unit 12 and the second standby unit according to the curvature classification.

As described above, according to the precut processing apparatus 1, the curved direction set based on the arrangement information and the bending direction detected by the processed material curvature detecting apparatus 4 are matched with each other from the processed material 100. Structural members can be manufactured. For this reason, for the processed material 100 containing a large curvature of a certain value or more, the structural member is manufactured by matching the direction of the curvature so that the direction of the large curvature faces the direction of one or more allowable curvatures corresponding to the arrangement information. be able to. Therefore, among a large number of structural members for assembling a building, it is possible to increase the target of the structural members that can use the processed material 100 including a large curvature of a certain value or more. Therefore, even if the processed material 100 contains a large curvature of a certain level or more, it is possible to efficiently manufacture a large number of structural members by reducing the situations where it is judged that the processed material 100 cannot be used as a defective product or it is cut into short pieces and used. can do.

Next, a suitable moving method of the crosspiece 200 used for laminating a large number of processed materials 100 supplied to the supply unit 11 will be described.

In A), the state switching mechanism 53 is shown in a simplified manner.

Is preferable. However, providing a dedicated device for removing the crosspiece 200 increases the cost of the precut processing device 1 as a whole, so that a device exhibiting other functions or one of the devices can be used. It is preferable to add a structure of the part so that the removal of the crosspiece 200 can be automated at low cost.

In the precut processing device 1, the crosspiece 200 is moved by using the motion control of the articulated robot 14a (see FIG. 1) as the moving mechanism of the suction unit 14b and the control device 6 (see FIG. 1) for controlling the operation thereof. It is configured to be possible. Specifically, as shown in FIG. 8A, a crosspiece removing portion 51 capable of moving in the vertical direction is attached to one end side of the suction portion 14b formed in a substantially rectangular parallelepiped shape in the longitudinal direction. There is.

Specifically, two rotating members 52 are rotatably attached to the suction portion 14b on both side surfaces intersecting in the longitudinal direction of the suction portion 14b, and a cross member is attached to one end side of the rotating member 52. The removing portion 51 is integrally attached. As shown in FIG. 8B, due to the rotation of the rotating member 52, the crosspiece removing portion 51 is located on the upper side and the processed material 100 can be moved in the processed material moving state (FIG. 8B). It is possible to switch between the solid line state) and the crosspiece moving state (the state of the alternate long and short dash line in FIG. 8B) where the crosspiece 200 is located on the lower side and can be moved. The switching between the processed material moving state and the crosspiece moving state is controlled by the state switching mechanism 53 attached to the upper side of the suction portion 14b, and the switching of this state is controlled by the control device 6. The state switching mechanism 53 is connected to, for example, an operating body 54 that contacts the end of the rotating member 52 and transmits rotational power to the rotating member 52, and is connected to the operating body 54 to move the operating body 54 up and down. It is composed of a pneumatic cylinder 55.

The crosspiece removing portion 51 is formed in the shape of a horizontally long thin plate having a thickness along the longitudinal direction of the suction portion 14b, and a brush (brush) in which a large number of elongated and deformable fibers are planted at the lower end portion thereof. ) -Shaped crosspiece contact portion 56 is provided. As shown in FIG. 8C, in a state where the processed material 100 in a cross-stacked state is supplied on the supply unit 11 of the processed material input device 3, and the crosspiece 200 is exposed at the uppermost stage, the crosspiece 200 is exposed.

When it moves, the crosspiece removing portion 51 moves along the longitudinal direction of the processed material 100 (the left-right direction in FIG. 8C), and this moving operation pushes the crosspiece 200 by the crosspiece removing portion 51 to process the processed material. Removed from above 100. For the operation control of the crosspiece removing unit 51 including the horizontal movement, the movement control of the suction unit 14b by the control device 6 can be used.

Further, the suction portion 14b is provided with a non-contact type sensor SK capable of detecting the position of the processed material 100 in the cross-stacked state, and the situation where the crosspiece 200 is exposed is determined by using the detection result of the sensor SK. Can be detected. For example, when one step of the processed material 100 is removed, the height and position of the upper surface of the remaining processed material 100 are measured from above by a non-contact sensor SK. It is possible to detect a situation in which the crosspiece 200 is exposed by detecting that the vertical height position fluctuates by the thickness of the crosspiece 200. Further, the state in which the processed material 100 for one stage is transferred to the processed material 100 in the piled state is determined by the sensor SK every time the processed material 100 for one stage is moved, depending on the presence or absence of the crossed material 200. Regardless of this, the crosspiece removing portion 51 may be configured to move along the uppermost stage of the processed material 100 in the crosspiece state so as to remove the crosspiece 200 when the crosspiece 200 is exposed. it can.

Even in this case, the processing material 100 may be moved. It is preferable that the crosspiece removing portion 51 is integrally provided at the contact portion that comes into contact with the material.

Further, it is not always necessary to separately provide the crosspiece removing portion 51 with respect to the suction portion 14b, and the crosspiece 200 may be sucked and removed by utilizing the function of lifting the object by the suction force of the suction portion 14b. Even in this case, since the moving mechanism of the suction unit 14b and the control of the movement of the suction unit 14b and the state switching of the suction non-adsorption state by the control device 6 can be used, the crosspiece 200 can be removed at low cost. Can be done.

Further, when the structure is such that the crosspiece 200 is adsorbed and moved, not only when the crosspiece 200 is adsorbed and removed, but also in the process of putting the processed material 100 into the crosspiece state, the processed material 100 is provided for one stage. After arranging the crosspieces 200, the crosspieces 200 may be moved so as to be adsorbed and lined up to bring the processed material 100 into a cross-stacked state, or the processed material 100 may be processed and manufactured. When the structural members are put into a stacking state, the suction force of the suction portion 14b may be used to place the crosspiece 200 on the structural members in which a plurality of members are arranged side by side.

In the case where the crosspiece 200 is sucked and moved, a plurality of crosspieces 200 are sucked so as to intersect each other in the longitudinal direction of the suction portion 14b with a gap in the longitudinal direction. It is preferable to transport a plurality of crosspieces 200 in one movement from the position of the crosspieces to the place where the crosspieces 200 are removed and put together. Further, even when the crosspiece 200 is moved onto the plurality of processed materials 100 in the process of putting the crosspieces 200 together from the place where the crosspieces 200 are stored together, the plurality of crosspieces 200 are collectively transported.
