Each part may be provided with a space in which the material 12, the part 13, or the residual material 15 can be placed. For example, the residual material 15 may be discharged onto the floor surface and collected later, or the component may be provided. The plate-shaped part manufacturing apparatus 1 may be configured by supporting 13a or the like with a thin plate-shaped pallet, or by arranging the material 12 on a movable carriage.

Next, the configuration of the component support portion 40 will be described in more detail.

The component support portion 40 has a configuration in which a region in which processed parts cut out from one material 12 can be arranged at least without overlapping vertically is secured as a component support region 40A.

The component support portion 40 is a component support area 40A, which is a region in which processed parts cut out from one material 12 and sequentially conveyed can be arranged at least, and at least one material 12 to be subsequently processed. The configuration may be such that an area in which the processed parts cut out from the above can be arranged can be secured. In the case of this configuration, in the component support portion 40, even if each component 13 based on the succeeding material 12 is conveyed before each component 13 based on the preceding material 12 is moved by the loading portion 70. They can be accepted, and it becomes possible to suppress the need to temporarily stop the operation of the processing unit 30 that processes the succeeding material 12 due to the progress of loading each part 13 based on the preceding material 12. .. Further, on the component support portion 40, the component 13 cut out from the continuously processed material 12 can be easily arranged in one layer.

Further, the component support unit 40 maintains a state in which various information (including direction identification information) added by the identification information addition unit 20 faces at least one side (upper side in FIG. 3) in the vertical direction, and is a processing unit. Even if the position or orientation of the machine 30 is displaced from the predetermined reference position or the predetermined reference direction during the machining, the transfer from the machining section 30 to the component support section 40, or the movement by the component support section 40. , The right side in a predetermined direction (right side in FIGS. 3A and 3B) without inverting the front and back of each component 13 so that various information can be read from the upper side of the component support portion 40. Move to (lower side of (C)).

Further, the control unit 90 (control means) identifies the direction of the machined part based on the direction identification information attached to the machined part supported by the part support part (machined part support means), and the control unit 90 (arrangement storage). It is possible to control the operation of the loading unit (loading means) so that the orientation of the parts is determined by the means) so that a predetermined number of plate-shaped parts are stacked in a plurality of layers. ing.

Specifically, the loading unit 70 can freely move the holding device 71 (contact part) and the imaging device 72 provided at the tip of the operating device 73 (operating unit) within the range shown by the broken line circle in FIG. It is configured to be movable, and has an axis in the vertical direction (direction perpendicular to the surface of the component 13 or the crosspiece member 14: vertical direction) passing through the holding center by the holding device 71 (for example, the suction center by the suction pad). It is configured to be rotatable as a central axis.

The case where the holding device 71 and the imaging device 72 move and rotate integrally (without changing their relative positions and orientations) will be described, but the holding device 71 and the imaging device 72 are configured to move and rotate individually. There may be. Further, in the following, for convenience of explanation, the control unit 90 is described as if it directly controls the movement and rotation of the holding device 71 and the imaging device 72, but the holding device 71 and the imaging device 72 are described below. The movement and rotation of the moving device 73 are indirectly performed by the operating device 73, and the control unit 90 controls the operation of the operating device 73.

As shown by the solid line in FIG. 3A, the control unit 90 is located in the vicinity of the position where the center of gravity of the component 13a to be moved is estimated to be located, and the upper surface of the component 13a (the control unit 90). Move it to a position separated by a predetermined distance from the surface to which the common symbol or barcode is added). After that, the control unit 90 searches for the common symbol 22 as the direction identification information based on the image captured by the imaging device 72.

If the control unit 90 can detect the common symbol 22 in the recognition range (hereinafter, also referred to as the wide area recognition range 72H) in which the presence or absence of the common symbol 22 can be identified by searching from that position, the broken line is shown in FIG. 3 (A). As shown by, the imaging device 72 is moved so as to approach the common symbol 22.

Specifically, the control unit 90 moves the imaging device 72 in a horizontal plane (a plane whose vertical direction is a perpendicular line) so that the common symbol 22 is located near the center of the wide area recognition range 72H (FIG. 3 (FIG. 3). C)), the common symbol 22 is photographed again, and the orientation of the common symbol 22 is recognized based on the photographed image. In this way, by taking a picture of the common symbol 22 after adjusting the position by moving again within the wide area recognition range 72H, the orientation of the common symbol 22, that is, the state of being supported by the component support area 40A. The orientation of the component 13 can be detected with high accuracy. The control unit 90 detects the difference between the recognized orientation of the component 13a and the orientation to be arranged in the laminated support portion 50, and as shown in FIG. 3B, axes the vertical direction by the angle of the difference. Rotate as.

The position adjustment control by moving the imaging device 72 so as to approach the common symbol 22 is not limited to the movement in the horizontal plane, and in addition, the common symbol 22 is identified from the wide area recognition range 72H. The narrow area recognition range 72L may be obtained by narrowing the possible recognition range. Specifically, after moving the component 13a in the height direction so that the distance from the surface of the component 13a is shorter and lower than the high position shown by the solid line, the common symbol 22 is photographed and the direction of the common symbol 22 is changed. You may try to recognize it. Further, the control for moving the imaging device 72 so as to approach the common symbol 22 is performed when the common symbol 22 is located within a certain range such as near the center in the first shooting in the wide area recognition range 72H. You may omit the shooting again.

Further, the control unit 90 reads out the information included in the barcode 21 which is the individual identification information from the image of the image pickup apparatus 72, and determines whether or not the component 13a is the movement target. For reading the information of the barcode 21, it is preferable to use an image taken by bringing the imaging device 72 close to the barcode 21 in order to display the barcode 21 in a small size or to include a large amount of information. , The shooting may be performed separately from the shooting of the common symbol 22, or the imaging device 72 may be brought closer to the barcode 21 before shooting.

If the detected barcode 21 is the barcode 21 of the component 13a to be moved, the control unit 90 moves the holding device 71 downward until it comes into contact with the component 13a. The recognition of the barcode 21 and the recognition of the common symbol 22 may be performed based on the image taken by one shooting.

After that, the control unit 90 operates the holding device 71 so as to hold the component 13a in a liftable state. In this case, even if the detected barcode 21 is that of the component 13 to be moved, the control unit 90 cannot support the component 13 to be moved in a predetermined holding mode, for example, FIG. Like the component 13b shown in (C), its center of gravity (tip of the arrow) is located in a predetermined area 40B near both ends of the support belt 43, and the center of gravity should be held so as to be the center of the holding device 71. Then, if the holding device 71 is supported at a position where it interferes with the fall prevention wall 45 that prevents the component 13 from falling from the support belt 43, it is initially set as a standard (reference or optimum). Judge whether it can be held by rotating it around the vertical axis passing through the center of gravity from the direction to be held, and if it can be held, hold it in a direction different from the standard, and if it still cannot be held, hold the standard Hold in a position away from the position to be in a predetermined direction. In this case, the control unit 90 stores information that identifies a change from the standard holding mode, for example, the rotation angle of the difference from the standard holding angle and the distance of the difference from the standard holding position. The movement and rotation of the holding device 71 are controlled by subtracting the holding deviation.

The control unit 90 has a configuration in which a plurality of holding positions and holding angles that are candidates when the component 13 cannot be held at a predetermined holding position and holding angle are set and stored in advance, and the component 13 is selected from the candidates. You may.

The control unit 90 raises the holding device 71 holding the component 13a to a predetermined height, and as shown in FIG. 3C, sets the direction of the common symbol 22 (component 13a) in the reference direction (in FIG. 3C). Rotate to match (downward). After that, the control unit 90 moves the holding device 71 back and forth and left and right to move the component 13a from above the component support area 40A to above the planned loading position scheduled to be arranged in the laminated support area 50A. After moving the component 13a above the planned loading position, the control unit 90 lowers the holding device 71 to bring it into contact with the component 13d, the short rail member 14S, and the long rail member 14L arranged in the lower layer. The control unit 90 releases the holding state of the component 13a by the holding device 71. As a result, the stacking in the predetermined position and orientation with respect to the component 13a is completed. The control unit 90 repeats the same control for the other parts 13b and 13c, and stacks them in sequence.

The control unit 90 describes a configuration for controlling the movement of the imaging device 72 so as to search for the common symbol of the component 13 to be moved by a route corresponding to the position of the common symbol 22 of the component 13 to be moved. However, the movement of the imaging device 72 may be controlled by a route according to the position of the component 13 to be moved, and even in this case, the common component 13 added to the component 13 to be moved as a result. The imaging device 72 can be brought closer to the common symbol 22 by a route corresponding to the position of the symbol 22.

Further, the control unit 90 may have a function of moving the imaging device 72 along one predetermined path that does not correspond to the position of the common symbol 22 to search for the common symbol 22. For example, a predetermined route that does not depend on the component 13 to be moved is set, and for example, the left end is moved from the rear side to the front side, then the center is moved from the rear side to the front side, and then the right end is moved. A zigzag path for moving from the rear side to the front side may be set, and the control unit 90 may control the movement of the imaging device 72 by a fixed route regardless of the component 13 to be moved. .. In a special situation where the control unit 90 cannot detect the common symbol 22 from the image of the wide area recognition range 72H, there is a component 13 that the component support unit 40 is searching for within a range in which the common symbol 22 can be recognized from above. You can check if it is or not anywhere.

Further, the control unit 90 moves the imaging device 72 along a certain path without setting the component 13 to be moved in advance, and the component 13 having the recognized common symbol is moved to the laminated support section 50 in the recognized order. You can also move it.

Further, when a special situation occurs in which the common symbol 22 cannot be detected from the image of the wide area recognition range 72H, for example, the position of the component 13 to be moved may be greatly deviated in the component support portion 40 (component support area 40A). When a situation occurs in which the component 13 gets under the other component 13, the control unit 90 may perform another predetermined process. For example, the occurrence of an error may be notified to the operator by the sound or display of the control unit 90 so that the operator can confirm the component 13 to be moved, and the direction (predetermined direction) with respect to the wide area recognition range 72H ( For example, the imaging device 72 may be moved by a predetermined distance along the moving direction in which the component 13 and the crosspiece member 14 can be moved in the component support portion 40, and the common symbol 22 may be searched again. Good. At this time, the control unit 90 preferably moves the imaging device 72 so that a part of the recognition range in which the common symbol 22 can be recognized overlaps before and after the movement, and the common symbol 22 can be detected by this movement as well. If not, the control unit 90 may further repeat the movement of the imaging device 72 in the same direction and the search for the common symbol 22. If the common symbol 22 cannot be detected by moving in the same direction, the common symbol 22 is moved along the direction intersecting the moving direction by a predetermined distance, and then along the moving direction in the same manner as described above. The search for the common symbol 22 may be performed while changing the position.

Further, for example, when the barcode 21 detected from the image of the wide area recognition range 72H is not a part to be moved (for example, part 13a) but another part (for example, parts 13b and 13c), the relevant part is concerned. Even if another part is moved, if all parts can be loaded on the layer for which the planned loading position is set, another part corresponding to the detected barcode 21 will be moved to the planned loading position. The control unit 90 may control the movement, that is, the control of changing the movement target according to the detection result of the identification information. Further, for another part (for example, parts 13b and 13c), another support base (temporary placing part) that can be temporarily placed is set in advance separately from the laminated support part 50, and the other part is used. It may be temporarily placed.

In this way, according to the plate-shaped component manufacturing apparatus 1, the operation of the loading unit 70 is controlled so that a predetermined number of plate-shaped component 13 including at least the component 13a and the like are stacked in a plurality of layers. The orientation of the component 13 is identified based on the common symbol 22 attached to the component 13a or the like supported by the component support unit 40, and the orientation of the component 13 is set to the orientation determined by the stacking mode determination program of the control unit 90. Matching control is performed. As a result, the orientation of the parts 13 when being machined from the material 12 is different from the orientation when the parts 13 are arranged in a stacked state, or the orientation of the parts 13 during machining or before being stacked by the loading portion 70. Even if there is a deviation, the orientation can be adjusted based on the common symbol 22 (direction identification information), and the component 13 can be arranged at a desired position in a desired orientation with high accuracy. it can. Therefore, the parts 13 can be suitably stacked, and the occurrence of load collapse due to the deviation of the orientation of the stacked parts 13 can be suppressed. Further, it is possible to prevent the parts 13 from protruding from the laminated support area 50A in which a predetermined number of parts 13 are stacked, and it is possible to prevent the protruding portion from being easily damaged during transportation to the construction site or at the construction site. ..

Further, in the case of the plate-shaped part manufacturing apparatus 1, the orientation of each part 13 having various shapes by being processed by the processing unit 30 can be specified by recognizing the direction identification information. Compared to the case where the outer shape of each component 13 having a different shape is individually recognized and its orientation is specified, the orientation of the component 13 can be specified at high speed based on a simple plate-shaped component movement program, and each component 13 can be located at a desired position. It can be arranged easily and at high speed in a desired orientation.

Further, according to the plate-shaped component manufacturing apparatus 1, different routes according to an estimated position where the component 13 to be moved or the common symbol 22 attached to the component 13 to be moved is likely to be located in the component support area 40A. The operation of the loading unit 70 is controlled so that the holding device 71 and the imaging device 72 come closer to the component support area 40A. As a result, the common symbol 22 of the component 13 to be moved can be searched from the vicinity of the position where the common symbol 22 is likely to be located, and the common symbol 22 of the component 13 to be moved can be efficiently recognized. can do. Therefore, each component 13 can be efficiently arranged at a desired position in a desired direction.

As a device for identifying the orientation of the component 13 based on the common symbol 22 attached to the component 13a or the like under the control of the control unit 90 and stacking the plate-shaped component 13 in a plurality of layers, the processing is performed. The same effect can be obtained not only by the plate-shaped part manufacturing apparatus 1 including the apparatus but also by configuring it as a plate-shaped component moving apparatus not including the processing apparatus. In this case, the material 12 in the control unit 90 The control part related to the processing of the above may be omitted.

Next, the configuration of the plate-shaped part manufacturing apparatus 1 relating to processing and use when the remaining portion of the material 12 is used as the processing rail member 14R will be described in detail.

The control unit 90 assigns the parts 13a and the like (processed parts) and the processing bar member 14R (crosspiece member) to the plate-shaped material 12 processed by the processing unit 30 (processing device), and assigns the processing section 30 (processing device). ) Is capable of performing machining control for machining the part 13a and the like and the machining bar member 14R. Specifically, the control unit 90 determines the position and orientation of the crosspiece member 14 required for each layer based on the execution of the above-mentioned stacking mode determination program. At this time, after the control unit 90 determines the allocation area for all of one or more parts 13a and the like cut out from each material 12, the control unit 90 processes the area in which none of the parts 13a and the like is allocated in each material 12. Allocate the crosspiece member 14R. Further, when the control unit 90 assigns the processing bar member 14R smaller than a predetermined size to the material 12, the outer shape thereof is changed to a specific shape, for example, the short crosspiece member 14S so that it is not necessary to identify the individual. Determine the same shape. The shape of the small processed rail member 14R is the same as that of the short rail member 14S so that they can be used in combination or in combination, but they do not have to be the same shape.

Based on the control of the control unit 90, the identification information addition unit 20 is the part 13 or the like or the machined rail member 14R on at least one surface of the machined rail member 14R facing the thickness direction, as in the case of the part 13a or the like. The identification information that can identify the person is attached. Specifically, the identification information addition unit 20 identifies the direction of the processed crosspiece member 14R, which is larger than a predetermined size, with a bar code corresponding to the bar code 21 similar to the bar code 21 as individual identification information. The same common symbol 22 as the part 13a or the like as information is printed, and only the same common symbol 22 as the part 13a or the like as the direction identification information is printed on the processing bar member 14R smaller than a predetermined size. The direction identification information attached to the machined crosspiece member 14R does not have to be the same common symbol as the part 13a or the like, and may be in another form as described above that can be adopted for the part 13a or the like, and further, the part 13a or the like. It may be a dedicated form that is not adopted for the above.

The component support portion 40 also supports the machined crosspiece member 14R with the common symbol 22 (direction identification information) facing at least one side in the vertical direction, as in the case of the component 13a and the like. Further, the component support portion 40 is supported by the processed rail member 14R separated from each component 13 or the like and other processed rail members 14R, as in the case of the component 13 or the like.

The control unit 90 could recognize the existence of the common symbol 22 in the search by the imaging device 72 of the component 13a or the like to be moved and the common symbol 22 attached to the component 13a or the like, but the bar code was placed at a predetermined position with respect to the common symbol 22. When the existence of 21 cannot be recognized, it is determined that the small machined bar member 14R is machined into a specific shape. Further, the control unit 90 is a case where the recognized bar code 21 is not a part 13a to be moved but a large machined bar member 14R, or a small machined bar member 14R where the bar code 21 is not recognized. Even if there is, even if the part 13a to be moved is moved before the movement is completed, it is recognized if any of the other parts 13 or the crosspiece member 14 cannot be arranged normally. The processed bar member 14R is moved.

As described above, according to the plate-shaped component manufacturing apparatus 1, the control unit 90 allocates the component 13a and the like and the machining bar member 14R to the material 12, and assigns the component 13a and the like and the machining bar member 14R to the machining section 30. At least one surface of the bar code and the common symbol 22 as identification information capable of distinguishing the part 13a and the like and the machined rail member 14R by the identification information addition unit 20 after being machined, facing the thickness direction of the part 13a and the machined rail member 14R. To be added to. As a result, it is possible to adjust the orientation of the processed part 13a or the like from the material 12 and the processed crosspiece member 14R based on the identification information and load the parts.

Further, since the common symbol 22 as the direction identification information is added to the processing crosspiece member 14R, it is possible to arrange the machined crosspiece member 14R in a position and direction determined by the control unit 90 (stacking mode determination program) with high accuracy. It becomes. Therefore, the parts 13a and the like and the processing rail member 14R can be suitably stacked, and the occurrence of load collapse due to the deviation of the orientation of the stacked parts 13a and the like and the processing rail member 14R can be suppressed.

Further, in the case of the plate-shaped part manufacturing apparatus 1, the processing bar member 14R used to assist the stable support of the part 13a and the like is processed from the remaining portion of the material 12 after the part 13a and the like are processed. Therefore, it is possible to improve the yield related to the processing of the parts 13a and the like and the processing rail member 14R.

Further, in the case of the plate-shaped component manufacturing apparatus 1, the orientation of the component 13a and the like and the processing rail member 14R can be adjusted based on the common symbol 22 as described above, so that the component 13a can be combined with one material 12. And when a plurality of machining targets including the machining bar member 14R are assigned, the orientation of the plurality of machining targets in the material 12 does not have to be aligned with the orientation determined by the control unit 90 (lamination mode determination program), and one material. The degree of freedom in combining a plurality of processing targets that can be assigned to 12 is increased. As a result, the yield related to the machining of the parts 13a and the like and the machining bar member 14R can be improved as compared with the case where the orientations of the plurality of machining targets in the material 12 are adjusted to the orientations determined by the control unit 90.

Further, as the plate-shaped component manufacturing apparatus 1, after the control unit 90 (stacking mode determination program) determines which of the plurality of layers the component 13a and the like and the processing rail member 14R are to be arranged, the plate-shaped component manufacturing apparatus 1 is used. It is possible to adopt a configuration in which the parts 13a and the like and the processing rail member 14R are assigned according to the determined position of the layer and the processing thereof is performed. When this configuration is adopted, the parts 13a and the like arranged in each layer in the plurality of layers and the processing rail member 14R are processed from the same material 12, and the material 12 is processed from the parts 13a and the like and the processing rail member 14R. It is possible to simplify the control of allocating and reduce the processing load. Further, the parts 13a and the like and the processing rail member 14R in each material 12 may be assigned so that the arrangement thereof is the same as the arrangement of the parts 13a and the like constituting each layer and the processing rail member 14R.

Next, the crosspiece member support portion 60 will be described in detail. FIG. 4A is a schematic top view showing an example of the configuration of the crosspiece support portion 60, FIG. 4B is a schematic front view thereof, and FIG. 4C is a single crosspiece member. It is a schematic side view which shows an example of the operation mode which supplies 14 (long rail member 14L), (D) shows an example of the operation mode which supplies a plurality of cross member 14 (long rail member 14L) at the same time. It is a side view.

As shown in FIGS. 1, 4 (A) and 4 (B), the crosspiece support portion 60 is an end portion of a long crosspiece member 14L (strip-shaped crosspiece member) in the longitudinal direction in a top view. It is configured to support by shifting the position of the above and arranging them side by side in the lateral direction intersecting in the longitudinal direction.

Specifically, as shown in FIGS. 4A and 4B, the crosspiece member support portion 60 serves as a wall projecting upward from an intermediate wall 61 having openings 61a to 61c on the front side. Longitudinal regulation walls 62a, 63a that regulate the positions of both ends of the long rail member 14L supported by (the lower side in FIG. 4A and the front side in the direction perpendicular to the paper surface in FIG. 4B). And the short side regulating wall 64a that regulates the positions of both ends of the long rail member 14L in the short side direction. Similarly, the longitudinal regulation walls 62b and 63b that regulate the positions of both ends of the long rail member 14L supported on the back side in the longitudinal direction, and the short side regulation that regulates the positions of both ends of the long rail member 14L in the lateral direction. The wall 64b is provided, and the longitudinal regulation walls 62b and 63b are provided so as to be offset from the longitudinal regulation walls 62a and 63a along the longitudinal direction of the long rail member 14L. The crosspiece member support portion 60 is supported in a state in which long crosspiece members 14L are stacked in a direction along various regulation walls.

Further, as shown in FIGS. 4 (A) and 4 (B), the crosspiece member support portion 60 is formed above the bottom wall 65 to support the intermediate wall 61 and has an opening 61a (openings 61b, 61c). On the lower surface of the support frame 66 having the openings 66a (openings 66b, 66c) that communicate with each other, and the long rail member 14L on the front side (back side) that is fixed to the bottom wall 65 and is located at the bottom layer in a stacked state. Drives a regulation plate 67a (regulation plate 67b) and a regulation plate 67a (regulation plate 67b) that are in contact with each other and can integrally move the long rail member 14L on the front side (back side) that is stacked in the vertical direction. It is provided with a cylinder 68a (cylinder 68b).

The control unit 90 brings two or more crosspiece members 14 into contact with the holding device 71 (contact portion) and lifts them, and two or more crosspieces on at least a part of the plurality of layers (layers constituting the laminated body 11). It is a configuration capable of controlling the movement of the members 14 together. For example, it may be configured to control the movement of two or more long rail members 14L together, or it may be configured to control the movement of two or more short rail members 14S together, and further, one or more. The long rail member 14L and one or more short rail members 14S may be controlled to be moved together.

Further, the control unit 90 holds the holding device 71 (contact portion) with respect to two or more long rail members 14L (strip-shaped crosspiece members) supported side by side by the crosspiece member supporting portion 60 (crosspiece member supporting means). ) Is located on the upper side, and the operation of the loading unit 70 (loading means) is controlled, and after the two or more long rail members 14L come into contact with the contact portion, the two or more long rail members 14L are lifted. , It is a configuration that controls the movement of a plurality of crosspiece members that collectively move a plurality of layers to at least a part of the layers. Further, only one long rail member 14L (strip-shaped crosspiece member) is brought into contact with the holding device 71 (contact portion) and lifted, and one long rail member 14L is attached to at least a part of the plurality of layers. It is also configured to control the movement of a single crosspiece member to be moved.

Specifically, the control unit 90 keeps the positions of the regulation plates 67a and 67b and the position of the upper surface of the uppermost long rail member 14L at a constant height H1 by controlling the operation of the cylinders 68a and 68b. When the uppermost long rail member 14L is taken out, the remaining stacked long rail members 14L are integrally controlled to be raised by the thickness of the long rail member 14L. Further, when the control unit 90 holds the uppermost layer long rail member 14L by the holding device 71, the holding device 71 is a portion where the front side and the back side long rail members 14L overlap along the longitudinal direction thereof. Moved to a position (hereinafter referred to as a holding standby position) in the center where the upper surface of the uppermost long rail member 14L and the lower end of the holding device 71 are at a predetermined distance H2 (for example, the thickness of the long rail member 14L). Let me. After that, the control unit 90 raises the regulation plates 67a and 67b by controlling the cylinders 68a and 68b until the upper surface of the uppermost long rail member 14L and the lower end of the holding device 71 come into contact with each other. The control unit 90 has a configuration in which the cylinder 68a and the cylinder 68b can be individually controlled, and as shown in FIG. 4C, the cylinder 68a or the cylinder 68b is operated (in the figure, the cylinder 68b is operated). Case), the long rail member 14L on the front side or the back side is raised, or as shown in FIG. 4D, the cylinder 68a and the cylinder 68b are operated at the same time to raise the long rail member 14L on the front side and the back side. It can be raised all at once. As a result, the control unit 90 can have the holding device 71 hold only a single long rail member 14L, or the holding device 71 can hold a plurality of (two in the figure) long rail members 14L. Further, although not shown, with respect to the short rail member 14S, as in the case of the long rail member 14L, the control unit 90 may cause the holding device 71 to hold only a single short rail member 14S (as in the case of the long rail member 14L). In the figure, two or four short rail members 14S) can be held by the holding device 71.

Here, the crosspiece member support portion 60 is provided so that the long crosspiece members 14L are lined up in the lateral direction intersecting the longitudinal direction in the top view. For this reason, the right end of the long rail member 14L on the front side in the longitudinal direction (the end on the side not facing the long rail member 14L on the back side: hereinafter abbreviated as the right end) is regulated on the longitudinal side. The other long rail member 14L on the back side is supported so as to be aligned with the wall 62a, and the left end portion in the longitudinal direction (the end portion on the side not facing the long rail member 14L on the back side: hereinafter abbreviated as the left end portion). It is a configuration that can be supported so as to be aligned by the longitudinal regulation wall 62b. As a result, even if the length of the long rail member 14L on the front side or the back side is not uniform in the longitudinal direction, the right end portion of the long rail member 14L on the front side and the left end portion of the long rail member 14L on the back side It is possible to keep the length separated by (hereinafter referred to as the total length of the staggered arrangement) constant. Further, in the crosspiece member support portion 60, the total length of the staggered arrangement is set to a length corresponding to the long side of the laminated support region 50A (see FIGS. 1 and 2), and the control section 90 is the crosspiece member support portion. If the two long rail members 14L are moved while maintaining the relative positions supported by 60, they can be arranged in just proportion over the long sides of the laminated support region 50A.

The crosspiece member support portion 60 has a configuration in which the long rail member 14L on the front side and the back side is supported so that the longitudinal direction thereof is substantially parallel to the long side of the laminated support region 50A, and the long rail member 14L is laminated. When arranged along the long side of the support area 50A, the long rail member 14L can be moved without rotation, which is easier to release than the linear movement in the holding state by the holding device 71. As a result, the long rail member 14L can be moved at a higher speed than when it is moved with rotation.

The crosspiece member support portion 60 is not limited to a configuration in which the long crosspiece members 14L on the front side and the back side are supported in a state of being close to each other in the short side direction, and the long rail members 14L are separated from each other in the short side direction at predetermined intervals. It may be configured to support in a state of being in a state of being.

Further, when the two long rail members 14L are moved, the control unit 90 does not necessarily have to be held at the same time, and may be held separately. That is, after holding one long rail member 14L on the front side and the back side by the holding device 71, the long rail member 14L is moved by the operating device 73 so as to be close to the other long rail member 14L. The other long rail member 14L may be held by the holding device 71.

Further, the crosspiece member support portion 60 is not limited to the case where a plurality of laminates in which the long crosspiece members 14L are stacked are provided side by side, such as on the front side and the back side, and may be configured to provide only one laminate. When this configuration is adopted, the control unit 90 holds one long rail member 14L by the holding device 71, moves the long rail member 14L by the operating device 73, and then moves the other long rail member 14L, and then another long rail member. The 14L is held by the holding device 71 at a portion different from the portion holding the long rail member 14L previously held. When the long rail member 14L is moved by the operating device 73, the total length of the staggered arrangement with respect to the two long rail members 14L held by the holding device 71 is adjusted by the amount of movement of the long rail member 14L along the longitudinal direction. The distance between the long rail members 14L is adjusted according to the amount of movement of the long rail members 14L along the lateral direction. Further, the crosspiece member support portion 60 is configured to align and support one end portion of the long rail member 14L in the longitudinal direction, and the control unit 90 holds the long rail member 14L to be held first, and then the long rail member After rotating 180 degrees with the front and back directions of 14L as the central axis, one end of the held long rail member 14L that is aligned in the supported state does not face the next held long rail member 14L. It is preferable to have a configuration in which the long rail member 14L is held. If this configuration is adopted, even if the length of the long rail member 14L in the longitudinal direction is uneven, the two long rail members 14L to be held are held. The total length of the staggered arrangement can be kept constant.

Further, the control unit 90 is not limited to the configuration in which the single crosspiece member movement control and the plurality of crosspiece member movement control are performed, and may be configured not to perform the single crosspiece member movement control. When this configuration is adopted, the crosspiece member support portion 60 has a structure in which the front side and back side long rail members 14L cannot be moved individually, for example, the cylinder 68a and the cylinder 68b operate only in conjunction with each other. It may be configured such that the long rail members 14L on the front side and the back side are supported by one regulating plate. When the control unit 90 moves one long rail member 14L by the single rail member movement control, the long rail member 14L on the front side and the long rail member 14L on the back side are used equally. , It is preferable to have a configuration in which they are alternately selected and moved. Further, when moving one long rail member 14L, the control unit 90 sets a position different from that when holding a plurality of long rail members 14L, for example, a position at the center (center of gravity) of each long rail member 14L. It is preferable that the position to be held by the holding device 71 is changed so as to be held by the holding device 71.

Further, the control unit 90 is not limited to a configuration in which when one or more items are held by the holding device 71, they are held closer to the center side (holding center) of the holdable area in the holding device 71. It may be configured to be held close to one end side. In this case, the control unit 90 moves what is held by the holding device 71 by the operating device 73 to a range farther from the base 74 (see FIG. 1) than when the holding device 71 is held closer to the center side. be able to.

As described above, in the plate-shaped component manufacturing apparatus 1, the operation of the loading means (loading unit 70) is at least controlled, and the component 13 and the long rail member 14L and the short rail member 14S are stacked in a plurality of layers. In the case of the state, two or more long rail members 14L and short rail members 14S are brought into contact with the contact portion (holding device 71) and lifted, and two or more long rail members are applied to at least a part of the plurality of layers. It is possible to control the movement of the 14L and the short rail member 14S together. As a result, two or more crosspiece members 14L can be lifted and moved to a desired position at one time, and the time efficiency of arranging the crosspiece members in each layer can be improved. As a result, plate-shaped or rod-shaped parts can be efficiently put into a stacked state including a plurality of crosspiece members.

Further, in the case of the plate-shaped component manufacturing apparatus 1, two or more crosspiece members 14L can be lifted at the same time, and the time efficiency for lifting the crosspiece members 14L and 14S can be improved. Further, by shifting the plurality of crosspiece members 14L in advance so as to have the same relative position as the relative position at the moving place, at least one of the crosspiece members 14L may be further moved after being moved on the layer. It is also possible to arrange two or more crosspiece members 14L at a desired position at the same time.

Further, in the plate-shaped part manufacturing apparatus 1, since it is possible to select whether to move a single crosspiece member or a plurality of crosspiece members, even for a layer that requires only one crosspiece member, A predetermined number of crosspiece members can be easily moved to a layer that requires a plurality of crosspiece members.

In addition, under the control of the control unit 90, two or more crosspiece members 14 are brought into contact with the contact portion (holding device 71) and lifted, and the two or more crosspiece members 14 are put together in at least a part of the plurality of layers. The device for controlling the movement is not limited to the plate-shaped part manufacturing device 1 including the processing device, and the same effect can be obtained even if the device is configured as a plate-shaped part moving device not including the processing device. .. Further, as the plate-shaped component moving device, at least one of the identification information addition unit 20 and the processing unit 30 may be omitted, or the control portion related to the processing of the material 12 in the control unit 90 may be omitted. ..

Further, the device that controls the movement of the two or more crosspiece members 14 together by the control of the control unit 90 is not limited to the case where the part to be moved by the loading unit 70 is the plate-shaped part 13, and is rod-shaped. The parts may be configured as a parts moving device to be moved, and for example, a crosspiece member used as a structural material such as a pillar material or a horizontal material forming a skeleton of a building or an auxiliary member such as a feather handle material. It may be used as 14. In this case, using the above-mentioned long rail member 14L, the long rail member 14L is arranged in a part of a state in which a plurality of rod-shaped parts are arranged and stacked in a plurality of stages, and two long rails are arranged according to the width of the truck bed. The overlap margin in the longitudinal direction may be adjusted by varying the amount of deviation of the end position of the member 14L, whereby the long rail member 14L is used as the crosspiece member 14 that can be adjusted to the width of the loading platform of various trucks. be able to.

Further, the control unit 90 is not limited to the configuration of performing the single crosspiece member movement control and the plurality of crosspiece member movement control, and may be configured to perform only the single crosspiece member movement control without performing the plurality of crosspiece member movement control.

Next, the configuration relating to the direction identification information added to the component 13 and the crosspiece member 14 by the identification information addition unit 20 will be further described with reference to FIG. FIG. 5 is a diagram illustrating a case where characters and symbols are used for the common symbol 22 used as direction identification information. Specifically, a barcode 21 and a common symbol 22 as identification information are added by the identification information addition unit 20 to a plurality of processed parts (part 13 and crosspiece member 14) manufactured by using one material 12. The formed form is schematically shown.

As shown in FIG. 5, the common symbol 22 that can be used as the direction identification information may be added by using characters or figures. As the common symbol 22, it is preferable to use characters, symbols, and figures that can be used by a personal computer as a control unit 90. Examples of characters include hiragana, katakana, alphabets, numbers, and kanji, and examples of symbols include "\" and "&". As the direction identification information used for the common symbol 22, only kanji or only symbols belonging to one type of classification may be used, or information belonging to two or more classifications may be used. ..

Further, among the character and symbol information, any information may be used as the common symbol 22 as the direction identification information, but it is used to identify the component 13 such as the number of the component 13 and the arrangement position of the component 13. It is preferable to use information (hereinafter, also referred to as “non-use information”) different from the existing information (hereinafter, also referred to as “usage information”). As a result, it is possible to avoid a situation in which the usage information is mistakenly recognized as the direction identification information.

Further, it is preferable to use kanji as the non-use information that can be used as the direction identification information. There are many types of kanji, and unused information can be easily selected from them, and there are many targets for later changes or additions, so changes and additions can be made easily. ..

Here, the common symbol 22 is printed by controlling the identification information addition unit 20 by the control unit 90. Therefore, the control unit 90 stores (sets) one or a plurality of types of non-use information that can be used as the common symbol 22 in advance, and the control unit 90 controls the identification information addition unit 20 for the non-use information. By inputting (adding) unset non-use information to the control unit 90, new non-use information that can be used as the common symbol 22 can be added. May be good.

As the kanji used as the direction identification information, a kanji having a shape capable of identifying a specific direction can be used. For example, kanji such as "soil", "yen", "mountain", and "de" can be used. If the kanji used as the direction identification information in this kanji setting is too simple, erroneous recognition may occur due to the grain or dirt of the part 13 when the wooden material is processed to manufacture the part 13. On the other hand, if it is too complicated, a high-resolution camera may be required to accurately identify the identification information, or if the distance is long, accurate identification may be difficult, and the positions where information can be input may be limited. There is. Therefore, as the kanji used as the direction identification information, for example, it is preferable that the number of strokes is three or more and not too simple, and it is preferable to use a kanji that is not too complicated such as five or less.

Further, as the kanji used as the direction identification information, it is preferable to use a kanji having linear parts facing in a plurality of directions. For example, rather than using a kanji such as the Chinese numeral "three", "ko" or "soil". Kanji such as "is preferable. As a result, it is possible to easily avoid a situation in which a large number of wood grains, which tend to be lined up in a certain direction, are mistakenly recognized as direction identification information.

Also, the direction can be limited to one direction even if the length of the straight line part changes slightly, compared to the kanji (for example, "Kou") that can be recognized as a character in another direction if the length of the straight line part changes slightly. It is preferable to use a Chinese character with a unique shape (for example, "earth"). As a result, it is possible to easily avoid a situation in which misrecognition is caused, such as the direction being reversed due to overlapping of wood grain or dirt on a part of the linear portion.

Further, it is possible to use a Chinese character (for example, "mountain") in which two or more linear parts facing at least one of a plurality of directions (for example, the vertical direction) are provided in parallel as direction identification information. It is preferable because it makes it easy to avoid erroneous recognition. Further, it is preferable to use a Chinese character (for example, "circle") in which two or more linear portions are parallel to each other in two directions as direction identification information.

Further, as the direction identification information, it is preferable that a plurality of types of common symbols 22 added by the identification information addition unit 20 are set. For example, a plurality of types of kanji as direction identification information are set in advance, and different characters are assigned to a plurality of parts 13 that are divided when a plate-shaped material is cut to add identification information. It is preferable to add by the part 20. As a result, when the common symbol 22 is detected by the control unit 90, it is possible to easily identify one component to be moved, only the common symbol 22 is detected, and the movement destination of the component 13 is controlled by the control unit. The 90 can be easily identified, and the loading unit 70 can be controlled to move the component 13.

When a plurality of types of identification information are used as the direction identification information, the characters or symbols added by the identification information addition unit 20 are printed in different sizes, and the direction identification information differs depending on the size of the characters or the like. This may be identified and controlled by the control unit 90. For example, the same kanji is added in different sizes to a part 13 that is divided into a plurality of parts 13 when a plate-shaped material is cut, and the part 13 is specified according to the type and size of the kanji. You may do so. FIG. 5 illustrates a case where the direction identification information of “¥” and “mountain” has different sizes and is used as the common symbol 22.

Further, as the number of types for setting the direction identification information, it is preferable to set the number of minutes that are separated from one material and need to be moved. For example, when a maximum of six parts 13 can be manufactured from one material 12, it is preferable to preset six or more different direction identification information. FIG. 5 illustrates a case where different direction identification information is added as the common symbol 22 to the three types of parts 13a to 13c.

Further, when a plurality of the same parts 13 (parts 13 having the same shape and size) are manufactured from one material 12 as the direction identification information, the same direction identification is performed for the same part 13. Information may be added. FIG. 5 illustrates a case where “mountain”, which is the same direction identification information, is added as a common symbol 22 to a crosspiece member 14 which is a processed part having the same shape and size.

Further, as the direction identification information, the same direction identification information may be added to a plurality of parts 13 manufactured by cutting one material 12. In this case, it is preferable to add the same direction identification information only when the same direction identification information printed on the plurality of parts 13 is separated by a predetermined distance or more. .. For example, control may be performed to add the same direction identification information to positions separated by a distance or more in which the same direction identification information is not arranged in the above-mentioned wide area recognition range 72H.

Further, as the direction identification information, the direction identification information having different colors is added to the plurality of parts 13, and the type of the direction identification information including the color of the added identification information is identified by the control unit 90, whereby the direction identification information May be determined.

Further, as the common symbol 22 added to one component 13, one character or symbol may be added as direction identification information, or a plurality of different identification information (for example, the type and size of the character or symbol) may be added. Identification information in which either or both are different) may be added. FIG. 5 illustrates a case where two types of direction identification information are added to each of the three types of parts 13a to 13c.

When a plurality of types of different identification information are added to one component 13 as a common symbol 22, the same character or symbol (for example, a Chinese character) may be added to a plurality of places with different sizes, or different characters or Symbols (for example, two types of kanji) may be added. In this case, for a plurality of types of identification information added to one component 13, the control unit 90 stores the relative positional relationship between the position of the center of gravity of the component 13 and the printing position, and any one of them is stored. If the identification information of the above can be detected, it is preferable to control the loading unit 70 so that the component 13 can be moved. FIG. 5 illustrates a case where direction identification information having different sizes is added to one component 13 as a common symbol 22.

Here, a control example in which a plurality of characters or symbols are added as direction identification information to one component 13 will be described. First, when an image of the component 13 to which a plurality of direction identification information is added is input to the control unit 90 via an information input device (imaging device 72), and one direction identification information can be detected in the image. The movement of the component 13 is controlled based on the direction identification information. When a plurality of direction identification information can be detected, the identification information having a higher ratio (score) of the correct part is used for movement control as compared with the data of the ideal direction identification information stored in advance. Control is executed as the direction identification information to be used. In this case, a plurality of types of direction identification information may be input to the control unit 90 by a plurality of shootings, but the information may be input to a position close enough to be input by a single shooting by the imaging device 72. It is preferable to add a plurality of types of direction identification information. As a result, a plurality of types of direction identification information can be input to the control unit 90 by a few information inputs (photographing), so that it is possible to easily speed up the control of the movement of the component 13.

As described above, the identification information addition unit 20 as the identification information addition means is set as the identification information for the part 13 and the crosspiece member 14 as the processed parts processed by the control of the processing unit 30 as the processing apparatus. A part (one or more) of a plurality of types of kanji or symbols is attached to a processed part as a common symbol 22. Therefore, the control unit 90 identifies the type and size of the kanji or symbol attached to the processed part, and the direction identification information composed of the combination of the type and size of the kanji or symbol attached to the processed part. The control unit 90 can be made to control the movement of the machined parts according to the type.

That is, when a plurality of processed parts are manufactured from one material 12, different direction identification information can be attached to the plurality of processed parts. In this case, the individual identification information such as the barcode 21 is input to the information input device. The machined part can be moved by specifying which of the plurality of machined parts is specified by the common symbol 22 without inputting to the control unit 90 by the (imaging device 72). Therefore, the low-resolution imaging device 72 can be used as an information input device for simplifying the input of identification information by the information input device and shortening the time required to complete the movement of the machined parts, or for inputting the direction identification information. Therefore, movement control using identification information (direction identification information) capable of identifying the orientation of the machined part can be preferably performed, such as reducing the cost of the plate-shaped part manufacturing apparatus 1.

Further, as the direction identification information set in the control unit 90, information on Chinese characters that can be generally used in a personal computer or the like is included. This makes it possible to easily set (select) appropriate identification information by diversifying the targets that can be set as identification information, and by using existing characters, it is possible to set the identification information for the control unit 90. , It is possible to easily set the identification control of the identification information based on the information input of the information input device (imaging device 72).

Further, as the direction identification information set in the control unit 90, different types of direction identification information are included because the size of the characters is different. Therefore, it is possible to perform control using various kinds of identification information by using limited characters and figures.

Next, the material (ink) used for adding the identification information by the identification information addition unit 20 will be described. The identification information is generally added by the identification information addition unit 20 using a colored ink such as black or dark blue by a printing device as the identification information addition unit 20, but the ink used for this printing is used. As a result, a fluorescent agent that receives ultraviolet rays and emits light may be used.

As a specific example, in the identification information addition unit 20 as a printing device, ink containing a fluorescent agent that emits light by receiving ultraviolet rays (hereinafter, also referred to as light emitting ink) is injected into an ink tank that stores the ink, and the light emitting ink is discharged. The bar code 21 and the common symbol 22 as identification information can be printed by using the bar code 21 and the common symbol 22. Further, a black light (ultraviolet light, UV light) is attached to the holding device 71 provided at the tip of the operating device 73 (operating unit) of the loading unit 70 in addition to the imaging device 72, and is controlled by the control unit 90. An image in which the black light is turned on and the identification information is emitted can be input to the control unit 90. The control unit 90 detects the common symbol 22 from the image including the light-emitting identification information, and controls the loading unit 70 according to the direction of the detected common symbol 22 to move the machined part.

By printing the identification information using the light emitting ink in this way, the printed information can be confirmed by using the black light. Therefore, the common symbol 22 as the identification information can be easily detected regardless of whether the color of the material (wood) to be precut is dark or close to white. it can. That is, regardless of the color of the material (wood) to be precut, and even if the grain or knot overlaps with the identification information, the identification information can be printed by the control unit 90 by printing with the light emitting ink. Can be easily detected accurately. As a result, it becomes difficult to identify the identification information, and it is possible to avoid a situation in which the process of moving the processed part based on the direction identification information is delayed, the progress of the work is delayed, or the operation is erroneously performed. Further, since it is not necessary to prepare a plurality of inks of different colors and use them properly according to the type of wood having different colors, it is possible to suppress an increase in cost by making the identification information addition unit 20 compatible with a plurality of colors. , It is possible to suppress the cost increase due to the control of the color change in the control unit 90.

Here, when the identification information addition unit 20 prints the identification information using the light emitting ink, the printing having the same or substantially the same outer shape as the printing using the light emitting ink is visually printed without receiving ultraviolet rays. As described above, the control unit 90 and the identification information addition unit 20 may be configured. For example, when not irradiating black light, identification information is printed using colorless (transparent) or substantially colorless (approximately transparent) light emitting ink (hereinafter, also referred to as “colorless light emitting ink”), and the colorless light emission is performed. Identification information is printed with black ink (colored dye ink or colored pigment ink that is visible when not irradiating black light, hereinafter also referred to as "colored ink") at the same position as printing with ink. You may do it. As a result, the identification information can be printed using only the light emitting ink only in the necessary part. In this case, as the control of the control unit 90, the identification information printed using only the light emitting ink, the identification information printed using only the colored ink, or both of the identification information, the light emitting ink, and the light emitting ink A control for printing may be provided by mixing the identification information printed using the colored ink.

Further, the identification information may be printed by the identification information addition unit 20 using ink that is a mixture of colorless light emitting ink and colored ink (hereinafter, also referred to as “colored light emitting ink”). In this case, by printing the identification information once, it is possible to print the identification information that can be visually recognized regardless of the presence or absence of ultraviolet rays in a short time.

In this way, by printing the identification information so as to be visible regardless of the presence or absence of ultraviolet rays, the control unit 90 identifies even when the black light is irradiated or even when the black light is not irradiated. The plate-shaped component manufacturing apparatus 1 can be made capable of identifying information and can be handled in various ways by the control unit 90. For example, the identification information can be detected by inputting the image irradiated with the black light to the control unit 90 only for the material having a color to which it is difficult to identify the identification information.

Here, information that is unnecessary at the construction site, such as direction identification information, may be printed with colorless light emitting ink so that it becomes almost colorless (transparent) if it is not irradiated with ultraviolet light. As a result, unnecessary printing on parts can be made inconspicuous at the construction site, which can spoil the appearance of the product or be understood by workers at the construction site as incorrect information. It is possible to reduce the possibility that it will end up.

Further, the printing of the identification information by the identification information addition unit 20 using the light emitting ink may be either one of the individual identification information and the direction identification information, or may include another information. For example, when a metal part (hardware) for joining with other members is attached to the end of a pillar or horizontal member, characters and figures are printed according to the attachment position and type of the hardware (hardware). (Printing) may be performed, or if it is necessary to manually perform post-processing on the processed part in addition to the pre-cut processing, characters or figures corresponding to the work content of the subsequent processing may be printed (printed). ..

The present invention is not limited to the above embodiment, and it can be easily inferred that various improvements and changes can be made without departing from the spirit of the present invention. It may be modified and carried out as follows.

In the above embodiment, in the plate-shaped part manufacturing apparatus 1, even if the processing is unnecessary by the processing unit 30 and the material 12 itself is used as the part 13, the identification information addition unit 20 and the processing unit 30 are used. Although the configuration of moving to the laminated support portion 50 through the component support portion 40 has been described, the material 12 which is a processing-free component may be directly moved from the material support portion 10 to the laminated support portion 50. ..

Further, in the above embodiment, the plate-shaped component manufacturing apparatus 1 has a configuration in which the component 13 and the crosspiece member 14 are moved by the loading portion 70, but the material 12 is also moved by the operating device 73, for example, the material support portion. The configuration may be such that the material 12 is moved from the identification information addition unit 20 to the identification information addition unit 20 or the material 12 is moved from the identification information addition unit 20 to the processing unit 30. Further, the plate-shaped component manufacturing apparatus 1 has a configuration in which the material 12 that does not need to be processed by the processing unit 30 is moved from the material support unit 10 and the identification information addition unit 20 to the laminated support unit 50 by the loading unit 70. May be good.

Further, in the above embodiment, the loading unit 70 of the plate-shaped part manufacturing apparatus 1 is controlled by the control unit 90, and the parts 13 and the crosspiece members 14 as processed parts are controlled based on the direction identification information (common symbol 22). Although it was configured to be stacked on a plurality of layers, it is not always necessary to use the direction identification information when the state is stacked on a plurality of layers, and instead of or in addition to this, it is not necessary to use the information. The machined parts may be moved using the direction identification information. For example, the direction identification information may be used in the control of the control unit 90 when the machined parts are moved to a support base that can be temporarily placed. ..

As described above, the present invention is suitable for printing devices and inks that can be used in printing devices.
