  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view for explaining the configuration of an object side surface photographing system 1 according to the present embodiment. FIG. 2 is a perspective view illustrating the configuration of the side surface position control device 2 of the present embodiment incorporated in the side surface photographing system 1.

  First, the overall configuration of the side photographing system 1 will be described with reference to FIG. The side surface photographing system 1 is a device for photographing a side surface of an object such as a building material M.

  The building material M described below is waste such as crushed materials and used parts generated at the construction site. Here, a description will be given using a building material M of an irregular plate-like body. The building material M is supplied from the sorting device 6.

  This sorting device 6 is a device that sorts waste materials by material such as aluminum, concrete, wood scrap, plastic, etc., and a member that has been conveyed by the belt conveyor 61 without being sorted by any of them is used as a building material M for the side surface photographing system 1. To be supplied.

  The side surface photographing system 1 is a device that discriminates a contained substance (for example, asbestos) or a material by photographing a side surface such as a fracture surface or an end surface of the building material M. The side surface photographing system 1 is mainly configured by a side surface position control device 2, a camera 4 as a camera device, and illuminations 5 and 5 as illumination devices.

  As shown in FIG. 2, the camera 4 is a photographing device that is set so as to focus on a region (photographing region 41) that is located when a second guide portion 32 described later is closed. The camera 4 may be a digital camera provided with an image sensor such as a CCD or CMOS, or may be an analog camera.

  For example, a near-infrared camera can be used if it is the camera 4 for determining the content of asbestos. In this case, the illumination 5 can be a light source that emits illumination light including a near infrared region, such as a halogen lamp.

  The camera 4 is disposed at a position facing the side surface position control device 2 with a discharge container 62 for storing the building material M discharged from the side surface position control device 2 interposed therebetween. On the other hand, as shown in FIG. 1, the illuminations 5 and 5 are arranged on both the left and right sides above the camera 4 to illuminate the imaging region 41 of the camera 4. In FIG. 2, the irradiation direction of the illuminations 5 and 5 is indicated by the optical axis 51.

  Then, the side surface position control device 2 includes a conveyor portion 21 in which the transport conveyors 211A and 211B are arranged in parallel, a first guide portion 31 in which a trough portion 311 is formed and can be opened and closed with respect to the conveyor portion 21, and a flat surface portion 321. And a second guide part 32 that can be opened and closed with respect to the conveyor part 21 is mainly provided.

  The conveyors 211A and 211B are belt conveyors that can independently switch the forward and reverse transport directions. Here, a direction from the sorting device 6 side to the camera 4 is a forward conveyance direction, and a direction from the camera 4 side to the sorting device 6 is a reverse conveyance direction.

  Further, when it is described that “the conveyor unit 21 is rotated forward (or reverse)”, it indicates that the transport directions of both the conveyors 211A and 211B are forward (or reverse).

  Further, a boundary 22 is defined between the transport conveyors 211A and 211B arranged in parallel. That is, the boundary 22 becomes a center line in the width direction of the conveyor portion 21 (a direction orthogonal to the transport direction).

  As shown in FIG. 3, the first guide portion 31 has a trough 311 in the forward conveyance direction formed at the position of the boundary 22, and a V shape in plan view formed at the same inclination angle on both sides of the trough 311. Inclined portions 312 and 312, and side wall portions 313 and 313 extending from the end portions of the inclined portions 312 and 312 along the outer edges of the conveyors 211 </ b> A and 211 </ b> B, respectively. For example, the 1st guide part 31 is shape | molded by planar view home base shape.

  As for the angle of the valley part 311 formed by the inclined parts 312 and 312, it becomes easier to fit the corner in the valley part 311 regardless of the shape of the building material M. However, if the angle is too wide, it becomes difficult to bring the building material M to the center by sliding the inner surfaces of inclined portions 312 and 313 described later. As a result of the experiment, when the angle of the valley 311 was set to about 100 degrees, the building material M could be brought close to the center.

  Even if the lower surface of the first guide part 31 is closed, it is separated from the upper surfaces of the transport conveyors 211A and 211B, so that the first guide part 31 does not interfere with the operation of the transport conveyors 211A and 211B. Absent. In short, when the first guide portion 31 is in a closed state, it is only necessary that the building material M cannot pass downstream even if the conveyor portion 21 rotates forward.

  On the other hand, if the conveyor part 21 rotates forward with the first guide part 31 open, the building material M can move downstream. That is, as shown in FIG. 4, the building material M can be passed by raising the inclined portions 312 and 312 with the side wall portions 313 and 313 as arms. In addition, the raising / lowering method of the inclination parts 312 and 312 is not limited to this method.

  In short, “openable and closable first guide portion 31” is a state in which the building material M conveyed by the conveyor portion 21 can pass without contacting the first guide portion 31 at any position in the width direction of the conveyor portion 21. Is a gate device in which “open” and a state in which the first guide portion 31 is not allowed to pass through are “closed”.

  By forming the side wall portions 313 and 313 in the first guide portion 31, it is possible to prevent the building material M being conveyed from falling from the conveyor portion 21. The first guide portion 31 can be made of any material such as steel or synthetic resin, but the friction coefficient on the inner surface side of the inclined portions 312 and 312 with which the building material M is brought into contact is limited.

  The friction coefficient on the inner surface side of the inclined portions 312 and 312 needs to be smaller than the friction coefficient on the upper surfaces of the conveyors 211A and 211B. By setting to such a friction coefficient, the building material M can be brought close to the trough 311 as described later.

  On the other hand, the second guide portion 32 is disposed so as to be closed on the downstream side of the first rotation from the first guide portion 31. As shown in FIG. 5, the second guide portion 32 includes a flat portion 321 that is substantially orthogonal to the forward conveyance direction, and the outer edges of the conveyance conveyors 211 </ b> A and 211 </ b> B from both sides of the flat portion 321. The side wall portions 322 and 322 extend. For example, the 2nd guide part 32 is shape | molded by planar view U shape.

  Since the lower surface of the second guide part 32 is separated from the upper surfaces of the conveyors 211A and 211B even in the closed state, the second guide part 32 will not interfere with the operation of the conveyors 211A and 211B. Absent. In short, when the second guide portion 32 is in a closed state, it is only necessary that the building material M cannot pass downstream even if the conveyor portion 21 rotates forward.

  On the other hand, if the conveyor part 21 rotates forward with the second guide part 32 opened, the building material M can move downstream. That is, as shown in FIG. 6, the building material M can be passed by raising the flat surface portion 321 using the side wall portions 322 and 322 as arms. In addition, the raising / lowering method of the plane part 321 is not limited to this method.

  In short, the “openable and closable second guide part 32” is a state in which the building material M transported by the conveyor part 21 can pass without contacting the second guide part 32 at any position in the width direction of the conveyor part 21. Is a gate device in which “open” is set, and a state where it cannot pass through contact with the second guide portion 32 is “closed”.

  By forming the side wall portions 322 and 322 in the second guide portion 32, it is possible to prevent the building material M being conveyed from falling from the conveyor portion 21. The second guide portion 32 can also be made of any material such as steel or synthetic resin.

  Next, a side photographing method of the building material M by the side photographing system 1 in which the side position control device 2 according to the present embodiment is incorporated will be described with reference to the drawings.

  The building material M transported by the belt conveyor 61 of the sorting device 6 adjacent to the side photographing system 1 is supplied by being dropped from the belt conveyor 61 to the side position control device 2 as shown by the arrow in FIG. Is done. At this stage, the first guide portion 31 and the second guide portion 32 of the side surface position control device 2 are in a closed state.

  The building material M placed on the end portion of the conveyor portion 21 of the side surface position control device 2 is conveyed toward the inclined portions 312 and 312 of the first guide portion 31 by the normal rotation of the conveyor portion 21.

  Here, as shown in FIG. 3A, it is assumed that the building material M is placed on the transport conveyor 211 </ b> B on the right side of the conveyor unit 21. The building material M is conveyed in the posture when it is placed until it contacts the first guide portion 31.

  When a certain part of the building material M comes into contact with the inclined portion 312, the building material M rotates and the first side surface M1 in the side surface comes into contact with the inner surface of the inclined portion 312 as shown in FIG. .

  Furthermore, since the conveyor unit 21 continues to rotate normally, the building material M moves toward the trough 311 by sliding on the inner surface of the inclined portion 312 having a smaller coefficient of friction than the upper surface of the conveyor 211B.

  As shown in FIG. 3C, when the corner of the building material M is within the valley 311, the building material M remains at that position even if the conveyor unit 21 continues to rotate forward. As a result, the building material M is brought to the center in the width direction of the conveyor portion 21 across the two conveyors 211A and 211B.

  Then, as shown in FIG. 4, the 1st guide part 31 is opened. When the first guide part 31 is opened, the building material M is conveyed until it comes into contact with the second guide part 32 by the forward rotation of the conveyor part 21.

  That is, when one corner of the building material M comes into contact with the inner surface of the flat portion 321 of the second guide portion 32 as shown in FIG. 5A, the building material M is rotated by the forward rotation of the transport conveyor 211B as shown in FIG. Rotate. When the rotation is controlled by a timer, for example, the forward rotation is continued for several seconds at a conveyance speed of about 20 cm / s. This rotation may occur from the contact point as a starting point, or may occur while sliding on the flat surface portion 321.

  On the other hand, depending on the shape of the building material M and the state of contact with the conveyors 211A and 211B, the corner that is stored in the valley 311 of the first guide part 31 directly contacts the flat part 321 of the second guide part 32, and the conveyor part 21 Even if it continues to rotate forward, it may balance in the left-right direction around the corner where the building material M contacts, and may not rotate quickly.

  Therefore, after the conveyor unit 21 is stopped when the first guide unit 31 is opened, the conveying direction of the conveying conveyors 211A and 211B arranged in parallel is set so that one conveying conveyor 211B is rotated forward and the other conveying conveyor 211A is reversed. Thus, by rotating in opposite directions, a step of changing the direction of the building material M can be added. The time for rotating the conveyors 211A and 211B in the opposite directions may be short (for example, 1 second or less at a conveying speed of about 20 cm / s), and the first side face M1 of the building material M It is preferable to carry out until it is substantially parallel to the flat portion 321.

  And as shown in FIG.5 (c), if the 1st side surface M1 of the building material M contacts the plane part 321 of the 2nd guide part 32, even if the conveyor part 21 continues normal rotation, the building material M will be in the position. Will stay. As a result, the first side face M1 of the building material M is positioned at the position of the flat surface portion 321.

  The position of the flat surface portion 321 of the second guide portion 32 is a position that matches the focusing range of the camera 4. Therefore, as shown in FIG. 6, the second guide portion 32 is opened and the first side face M <b> 1 of the building material M is photographed by the camera 4. By this photographing, it is possible to record an image of the first side face M1 oriented so as to be substantially orthogonal to the conveying direction of the conveyor unit 21.

  Through the steps so far, a clear image of the first side face M1 of the building material M can be obtained. By analyzing the image of the first side face M1 obtained in this way, it is possible to determine whether asbestos is included, for example.

  With the side surface position control device 2 of the present embodiment, another side surface can be photographed following the first side surface M1. In that case, first, the conveyor part 21 is reversed as shown in FIG.

  This backward movement is performed up to a position beyond the region located when the first guide portion 31 is closed. At this stage, the first guide portion 31 is open. Moreover, the distance which reverses the building material M can be implemented by control which reverses the conveyor part 21 only for the time set using the timer.

  And, as shown in FIG. 8, by rotating the transfer conveyors 211A and 211B in parallel, one transfer conveyor 211B is normal rotation, the other transfer conveyor 211A is reverse rotation and rotated in opposite directions, The direction of the building material M is changed.

  That is, since the building material M is disposed across the two transfer conveyors 211A and 211B by being centered by the first guide portion 31, the building material M is rotated by rotating the transfer conveyors 211A and 211B in parallel in the opposite directions. Can be swiveled.

  Here, the transport conveyors 211A and 211B arranged in parallel can be installed so that the upper surfaces thereof are horizontal, but can be inclined in a direction facing each other across the boundary 22 as shown in FIG.

  As shown in FIG. 9, by inclining the conveyors 211A and 211B at an inclination angle R with respect to the horizontal, the contact area between the bottom surface of the building material M and the upper surface of the conveyors 211A and 211B is reduced, making it easier to turn. Become. Moreover, even when the lower surface of the building material M is not flat, both sides of the building material M can be brought into contact with both the conveyors 211A and 211B. Furthermore, the left-right bias during turning can be reduced.

  The inclination angle R of the conveyors 211A and 211B was confirmed to be 1 to 2 degrees as a result of experiments. In particular, good results were obtained when the inclination angle R was 2 degrees.

  On the other hand, the angle at which the building material M is turned can be controlled by controlling the conveying directions of the conveying conveyors 211A and 211B in opposite directions for a time set using a timer.

  The turning time is set to be longer than the time required for the building material M having the assumed maximum outer dimension to face another side (90 degrees for a substantially rectangular shape) (for example, several seconds at a conveyance speed of about 20 cm / s). For this reason, the building material M having a relatively small external dimension is turned a plurality of times and directed to another side face during the same timer time.

  Then, both the conveyors 211A and 211B are rotated forward in a state where the second side surface M2 different from the first side surface M1 faces the camera 4 side. Here, the center of the building material M may be displaced from the boundary 22 of the conveyor unit 21 due to the turning of the previous process or the like.

  Therefore, in order to prevent this displacement, it is preferable to add a step of closing the first guide portion 31 and bringing the building material M to the center again by the first guide portion 31. After centering the building material M, the first guide part 31 is opened and the conveyor part 21 is stopped. At this stage, the second guide portion 32 is closed.

  Then, as described above, the transport conveyors 211 </ b> A and 211 </ b> B are rotated in opposite directions for a short time so that the second side face M <b> 2 of the building material M is substantially parallel to the flat surface part 321 of the second guide part 32.

  Subsequently, by causing the conveyor unit 21 to rotate forward, the second side surface M2 of the building material M is brought into contact with the flat surface portion 321 of the second guide portion 32 as shown in FIG. When the building material M comes into contact with the flat surface portion 321 of the second guide portion 32, the second side surface M2 of the building material M is positioned at the position of the flat surface portion 321 as described above with reference to FIG. .

  Therefore, the second guide portion 32 is opened in the same manner as shown in FIG. 6, and the second side face M <b> 2 of the building material M is photographed by the camera 4. Such positioning and photographing of different side surfaces of the building material M can be repeated as many times as necessary.

  Then, as a result of photographing a plurality of side surfaces (M1, M2), the building material M for which no problem has been found is dropped by normal rotation of the conveyor unit 21, and is accommodated in the discharge container 62.

  Next, operations of the side surface position control device 2 of the present embodiment, the side surface photographing system 1 in which the side surface position controlling device 2 is incorporated, and the side surface photographing method of the building material M will be described.

  The side surface position control device 2 according to the present embodiment configured as described above closes the first guide portion 31 and causes the conveyor portion 21 to rotate forward so that the building material M is formed into a central valley portion 311 having a V shape in plan view. Can be sent. Moreover, the side surface (M1, M2) of the building material M can be disposed at the position of the flat surface portion 321 of the second guide portion 32 by closing the second guide portion 32 and causing the conveyor portion 21 to rotate forward.

  For this reason, even if the building material M is supplied to the conveyor unit 21 in any direction, the position of the side surface (M1, M2) of the building material M can be positioned at the position of the flat surface part 321 of the second guide unit 32. .

  In particular, even when the shape of the building material M is an irregular shape and there is no linear side surface, a broken surface such as a side can be positioned with respect to the flat portion 321.

  Furthermore, if the conveyors 211A and 211B are belt conveyors, they can be reliably conveyed even if the building material M is small or elongated.

  The side photographing system 1 for the building material M according to the present embodiment includes a side position control device 2 and a camera 4. For this reason, the side surface (M1, M2) of the positioned building material M can be easily photographed by the camera 4. That is, since the distance between the side surface (M1, M2) of the building material M and the camera 4 can be made constant, a camera that does not have an automatic focusing function that is often used in industrial cameras or near infrared cameras. Even if it is 4, a clear image can be easily taken.

  Further, by arranging the illuminations 5 and 5, the performance of the camera 4 is supplemented and a clear image can be taken. For example, when a near-infrared camera is used, it can be stabilized in a state suitable for photographing by irradiating illumination light including a near-infrared region.

  Further, in the side photographing method of the building material M according to the present embodiment, the first guide part 31 is positioned in contact with the flat part 321 of the second guide part 32 and the step of bringing the building material M to the center of the conveyor part 21. A step of photographing the first side face M1 of the building material M. For this reason, the first side face M1 of the building material M can be clearly photographed by the camera 4.

  Furthermore, by changing the direction of the building material M with the conveying directions of the conveying conveyors 211A and 211B arranged in parallel opposite to each other, the second side surface M2 which is another side surface of the building material M different from the first side surface M1 is also the camera 4. You can shoot.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.

  For example, in the above-described embodiment, the case where the conveyors 211A and 211B are installed at an inclination angle R has been described. However, the present invention is not limited to this, and the conveyors 211A and 211B may be installed horizontally. it can.

  Moreover, in the said embodiment, although demonstrated while exemplifying the plate-shaped building material M as an object, it is not limited to this, The present invention is also applied to positioning of a side surface of an article other than a block or a building material. Can be applied.
