(Details of moving mechanism)
Next, the moving mechanism 54 will be described in detail with reference to FIGS. 5 to 7. FIG. The moving mechanism 54 includes a forward/backward moving mechanism 60 (an example of a "first moving mechanism") that displaces the component analyzer 56 along the front-rear direction (an example of the "first direction", the X direction in the figure), and a left-right direction. A horizontal movement mechanism 70 (an example of a “second movement mechanism”) that displaces the component analyzer 56 in (an example of a “second direction”, the vehicle width direction, the Y direction in the figure) and a vertical direction (a “third direction”). , a vertical movement mechanism 80 (an example of a “third movement mechanism”) that displaces the component analyzer 56 in the height direction, the Z direction in the figure). For example, the front-rear direction and the left-right direction are directions along (preferably substantially parallel to) the loading surface of the loading platform 14 , and the vertical direction is a direction intersecting (preferably substantially perpendicular to) the loading surface of the loading platform 14 .

As shown in FIGS. 2 and 5, the front-rear movement mechanisms 60 are provided in pairs on both sides of the loading platform 14 in the left-right direction. In the following description, one of the paired back-and-forth moving mechanisms 60 will be described, but the same description applies to the other. The longitudinal movement mechanism 60 comprises a front fixed end 61, a rear fixed end 62, a front and rear rack 63 between the front and rear fixed ends 61 and 62, and a front and rear movable portion 64 on the front and rear rack.

As shown in FIGS. 5 and 6, the front fixed end 61 is supported at the front corner of the loading platform 14 by a vertical movement mechanism 80, which will be described later, and fixed at a predetermined position. The rear fixed end 62 is supported at a rear corner of the loading platform 14 by a vertical movement mechanism 80, which will be described later, and is fixed at a predetermined position. When the front fixed end 61 and the rear fixed end 62 are fixed at a position higher than the upper end of the loading platform 14, physical interference between the scrap S loaded on the loading platform 14 and the back-and-forth movement mechanism 60 is suppressed. preferable.

As shown in FIG. 6 , the front-rear rack 63 has one end fixed to the front fixed end 61 and the other end fixed to the rear fixed end 62 . extend to The front-rear rack 63 has uneven portions 63a that are regularly formed from one end to the other end. When the concave-convex portion 63a is provided on the lower surface of the front-rear rack 63, it is preferable in that it is more protected from rain and scrap S during loading than when provided on the upper surface.

The front-back direction movable portion 64 includes a main body 65 , a motor 66 provided inside the main body 65 , and a pinion gear 67 interlocking with the motor 66 . The main body 65 has a through hole 68 extending in the front-rear direction. The front-rear direction rack 63 extends through the through hole 68 and functions as a rail that guides the movement of the front-rear direction movable portion 64 . The pinion gear 67 is arranged so as to mesh with the uneven portion 63 a of the front-rear rack 63 .

When the motor 66 rotates, the pinion gear 67 connected to the motor 66 rotates together. When the pinion gear 67 rotates, the front-rear direction movable portion 64 moves in the front-rear direction along the front-rear direction rack 63 meshing with the pinion gear 67 . When the motors 66 of the pair of front-rear moving mechanisms 60 operate in conjunction, the pair of front-rear direction movable portions 64 move so as to maintain the same position in the front-rear direction, as shown in FIG. By moving the pair of front-rear direction movable parts 64 in the front-rear direction, the horizontal movement mechanism 70 supported between the front-rear direction movable parts 64 and the component analyzer 56 attached to the horizontal movement mechanism 70 are also interlocked with each other in the front-rear direction. move to

As shown in FIGS. 5 and 7 , the left/right movement mechanism 70 is provided between the pair of front/rear direction movable portions 64 . The left/right movement mechanism 70 includes a left/right direction rack 71 and a left/right direction movable portion 72 . A component analyzer 56 is attached to the laterally movable portion 72 so as to face the scrap S on the loading platform 14 .

As shown in FIG. 7 , the left-right direction rack 71 has one end fixed to one of the front-rear direction movable parts 64 and the other end fixed to the other front-rear direction movable part 64 . It extends in the left-right direction between the movable parts 64 . The left-right rack 71, like the front-rear rack 63, has uneven portions 71a that are regularly formed from one end to the other end. When the concave-convex portion 71a is provided on the lower surface of the left-right direction rack 71, it is preferable in that it is more protected from rain and scrap S during loading than when provided on the upper surface.

The left-right direction movable portion 72 includes a main body 73 , a motor 74 provided inside the main body 73 , and a pinion gear 75 interlocking with the motor 74 , similarly to the front-rear direction movable portion 64 . The main body 73 has a through hole 76 extending in the left-right direction. The horizontal rack 71 extends through the through hole 76 and functions as a rail that guides the movement of the horizontal movable portion 72 . The pinion gear 75 is arranged so as to mesh with the uneven portion 71 a of the left-right direction rack 71 .

As with the longitudinally movable portion 64, when the motor 74 of the laterally movable portion 72 rotates, the pinion gear 75 connected to the motor 74 rotates together. When the pinion gear 75 rotates, the left-right direction movable portion 72 moves in the left-right direction along the left-right direction rack 71 meshing with the pinion gear 75 . As the left-right direction movable part 72 moves in the left-right direction, the component analyzer 56 attached to the left-right direction movable part 72 also moves in the left-right direction.

In this manner, the component analyzer 56 can be two-dimensionally moved (for example, along the loading surface of the loading platform 14) by the front-rear movement mechanism 60 and the left-right movement mechanism 70. FIG. Thereby, the scrap S loaded on the platform 14 can be analyzed at various positions.

Next, the vertical movement mechanism 80 will be described. As shown in FIGS. 6 and 7 , the vertical movement mechanism 80 is provided below each of the four fixed ends 61 , 61 , 62 , 62 positioned at the four corners of the loading platform 14 . In the following description, one vertical movement mechanism 80 will be focused on, but the same description applies to the other three mechanisms. The vertical movement mechanism 80 includes a lower fixed end 81 , a vertical rack 82 and a height adjuster 83 .

As shown in FIG. 6, the lower fixed end 81 is supported at a predetermined height position. The vertical rack 82 has one end fixed to the lower surface of the front fixed end 61 or the rear fixed end 62 and the other end fixed to the upper surface of the lower fixed end 81 so that the front fixed end 61 or the rear fixed end 62 and the lower fixed end are fixed. 81 in the vertical direction. The vertical rack 82 has uneven portions 82a formed regularly from one end to the other end on at least one surface.

The height adjustment part 83 is attached and fixed to the side wall of the loading platform 14 . The height adjuster 83 includes a main body 84 , a motor 85 provided inside the main body 84 , and a pinion gear 86 interlocking with the motor 85 . The main body 84 has a through hole 87 extending vertically. The vertical rack 82 extends through the through hole 87 . The pinion gear 86 is arranged so as to mesh with the uneven portion 82 a of the vertical rack 82 .

When the motor 85 rotates, the pinion gear 86 connected to the motor 85 rotates together. Since the height adjusting portion 83 is fixed to the side wall of the loading platform 14, when the pinion gear 86 rotates, the vertical rack 82 meshing with the pinion gear 86 moves vertically. When the motors 85 of the four height adjustment units 83 operate in conjunction, the four vertical racks 82 move up and down so as to maintain the same height. Similarly, the four front fixed ends 61 and the four rear fixed ends 62 of the upper end of the vertical rack 82 move up and down so as to maintain the same height. As a result, the forward/backward movement mechanism 60, the left/right movement mechanism 70, and the component analyzer 56 attached to the left/right movement mechanism 70 are also moved in the vertical direction.

In this manner, the vertical movement mechanism 80 can vertically move the forward/backward movement mechanism 60 , the left/right movement mechanism 70 , and the component analyzer 56 . Thereby, the height position of the component analyzer 56 can be adjusted. Therefore, for example, when the amount of scrap S is large, physical interference between the component analyzer 56 and the scrap S can be avoided by moving the component analyzer 56 upward. 4 ( By means of the "measuring device UP" button 402 and the "measuring device DOWN" button 404) in a), the movement mechanism 54 can be instructed to move the component analyzer 56 up and down as necessary.

(Creation of analysis sequence)
The analysis device 50 can analyze the scrap S at a plurality of positions on the platform 14 by moving the component analyzer 56 on the platform 14 using the moving mechanism 54 . Specifically, the detection unit 56 a can detect electromagnetic waves from the scrap S at a plurality of positions on the loading platform 14 . The position on the platform 14 where the component analyzer 56 analyzes is not particularly limited. For example, the control unit 52 can generate, as an instruction to the movement mechanism 54, a movement sequence including information on analysis positions where the component analyzer 56 performs analysis. Such a movement sequence includes, for example, information on analysis positions on the platform 14 and information on movement routes passing through each analysis position.

For example, the control unit 52 can generate a movement sequence by the following processing.
(1) The in-vehicle device 40 acquires information about the size of the loading platform 14 by receiving an input from the user.
(2) The in-vehicle device 40 transmits the acquired information about the size of the loading platform 14 to the analysis device 50 .
(3) The storage unit 58 stores information about the size of the loading platform 14 received from the in-vehicle device 40 .
(4) The control unit 52 determines the number of measurement points by the component analyzer 56 based on the input from the user and information on the size of the loading platform 14 stored in the storage unit 58 .
(5) Based on the determined number of measurement points, the control unit 52 determines the analysis position (that is, the position of the measurement point) on the platform 14 and the movement route of the component analyzer 56 .

In (5) above, for example, the control unit 52 substantially divides the measurement area on the loading platform 14 (eg, the entire loading surface of the loading platform 14) so that the analysis positions are arranged on the loading platform 14 at substantially equal intervals. can be set as the analysis position. The control unit 52 can determine the interval between each analysis position based on, for example, the angle of view of the detection unit 56a. The control unit 52 can set the movement route of the component analyzer 56 so that the set analysis position can be followed by the shortest route. However, the method of setting the analysis position and movement route is not limited to the above example, and any method can be used. For example, the control unit 52 may set the analysis position at random, or may set the analysis position based on the image recognition result of the photographed image of the scrap S on the loading platform 14 . Thus, the control unit 52 can generate an instruction to the moving mechanism 54 for moving the component analyzer 56 on the loading platform 14 based on the size of the loading platform 14 stored in the storage unit 58 . .

The control unit 52 may refer to the correspondence table 900 stored in the storage unit 58 to determine the movement sequence. FIG. 9 is a diagram showing a correspondence table 900 between the size of the vehicle 10 and the movement sequence of the analysis device 50. As shown in FIG. The correspondence table 900 stores the vehicle type of the vehicle 10 and the size of the loading platform 14 thereof (that is, the length in the front-rear direction, the width in the left-right direction, and the height in the vertical direction), the number of measurement points, and a specific movement sequence. are associated. Therefore, the control unit 52 refers to the correspondence table 900 to acquire the movement sequence corresponding to the size of the loading platform 14 stored in the storage unit 58, and generates an instruction to the movement mechanism 54 based on the movement sequence. can do.

(Movement to evacuation position)
When the component analyzer 56 is not performing an analysis (specifically, when the detection unit 56a does not detect X-rays from the scrap S), the control unit 52 controls the component analyzer 56 to a predetermined value. The moving mechanism 54 can be controlled to move to the retracted position RP. In FIG. 5, the solid line indicates the measurement position MP where the detection unit 56a of the component analyzer 56 measures, and the broken line indicates the retracted position RP. The retracted position RP is preferably positioned in front of the loading platform 14 . In FIG. 5 , the retracted position RP is positioned at the front right end of the loading platform 14 . When the component analyzer 56 is at the retracted position RP, physical interference between the component analyzer 56 and the scrap S is avoided when the scrap S is loaded onto the loading platform 14 or unloaded from the loading platform 14.例文帳に追加be able to. In particular, if the retracted position RP is located in front of the loading platform 14, it is possible to prevent physical contact between the scrap S falling backward and the component analyzer 56 during dumping as shown in FIG. As shown in FIGS. 2 and 6, the configuration in which the loading platform 14 has the roof 14a above the retracted position RP is a physical separation between the scrap S and the component analyzer 56 when the scrap S is loaded onto the loading platform 14 from above with a crane or the like. It is preferable in that it is possible to prevent direct contact. In this way, by moving the component analyzer 56 to the retracted position RP, damage to the component analyzer 56 during loading and unloading can be suppressed or prevented.

For example, the control unit 52 can instruct the moving mechanism 54 to move the component analyzer 56 to the retracted position RP in response to the completion of the predetermined analysis work by the component analyzer 56 . In addition, the control unit 52 responds to receiving a command from the driver 16 to stop the analysis work of the component analyzer 56 (for example, pressing the “measurement stop” button 408 in FIG. 4). The moving mechanism 54 may be instructed to move the analyzer 56 to the retracted position RP. Note that the component analyzer 56 does not always have to be positioned at the retracted position RP while analysis is not being performed. For example, the moving mechanism 54 may move the component analyzer 56 to the retracted position RP in response to an instruction from the driver 16, for example, at a specific timing such as when loading or unloading cargo.

<Management device 32>
Next, the management device 32 of the destination facility 30 will be described. The management device 32 manages the destination facility 30 as a whole.

The management device 32 can output instructions to the driver 16 and the manager 36 via the transfer destination terminal 34 and the in-vehicle device 40 based on these pieces of information.

<Conveyance destination terminal 34>
Next, referring to FIG. 3, the destination terminal 34 will be described. A destination terminal 34 (an example of a “presentation device”) is a terminal operated by an administrator 36 in the destination facility 30 . For example, the destination terminal 34 is a computer terminal installed in the monitoring room or facility management room at the entrance gate of the destination facility 30 . Specifically, similarly to the in-vehicle device 40, the destination terminal 34 includes, as its functional units, an operation unit 34a, a processing unit 34b, a display unit 34c, and a storage unit 34d. These functions and configurations are the same as or similar to those of the operation unit 42 , the processing unit 44 , the display unit 46 and the storage unit 48 of the in-vehicle device 40 . Specifically, the operation unit 34a receives an input operation from the administrator 36. FIG. The processing unit 34b performs predetermined arithmetic processing on the information acquired by the destination terminal 34 . The display unit 34c presents the information output by the processing unit 34b to the administrator 36 by displaying the information as characters or images. The storage unit 34d stores various programs executed by the processing unit 34b, various data used for processing in the storage unit 34d, and the like.

The transport destination terminal 34 may be connected to the in-vehicle device 40 and the analysis device 50 via the network N. FIG.

The destination terminal 34 can acquire the analysis result (an example of “analysis information”) of the scrap S by the analysis device 50 . The destination terminal 34 may directly acquire the analysis result transmitted from the in-vehicle device 40 or the analysis device 50 , or may acquire the analysis result received by the management device 32 . Further, the destination terminal 34 can acquire unloading information (an example of "analysis information") regarding the unloading sites P1, P2, and P3 where the scrap S is unloaded based on the analysis result. The unloading site for unloading the scrap S can be determined based on the types and amounts of impurities in the scrap S obtained from the component analysis. The unloading site for unloading the scrap S may be determined by the management device 32 or the destination terminal 34 based on a predetermined correspondence table or algorithm. good too. The destination terminal 34 can transmit the acquired unloading information to the in-vehicle device 40 .

<Processing Flow of Analysis System 1>
Next, a processing flow of the analysis system 1 will be described with reference to FIG. 10 . FIG. 10 is a flow chart showing the processing flow of the analysis system 1 according to this embodiment.

First, in step S<b>1001 , the in-vehicle device 40 receives an analysis start instruction from the driver 16 . The driver 16 inputs an analysis start instruction to the in-vehicle device 40 by pressing a "measurement start" button 406 on the input screen 400 shown in FIG. 4(a), for example. Note that the instruction to start the analysis may be input via an input unit such as a button provided on the vehicle 10 or the analysis device 50 instead of being input to the in-vehicle device 40 .

In step S<b>1002 , the in-vehicle device 40 transmits the analysis instruction received from the driver 16 to the analysis device 50 . In step S<b>1003 , the analysis device 50 executes analysis by controlling the moving mechanism 54 and the component analyzer 56 based on the analysis instruction received from the vehicle-mounted device 40 . The controller 52 can generate a predetermined movement sequence and control the movement mechanism 54 and the component analyzer 56 based on the movement sequence. As the moving mechanism 54 scans the component analyzer 56 on the loading platform 14 , the analysis device 50 acquires analysis results at a plurality of positions on the loading platform 14 .

Before or during the measurement, in response to the driver 16 pressing the "measuring device UP" button 402 or the "measuring device DOWN" button 404 in FIG. can be sent to the control unit 52 . Upon receiving the vertical movement instruction, the control unit 52 instructs the vertical movement mechanism 80 to move the component analyzer 56, the forward/backward movement mechanism 60, and the left/right movement mechanism 70 in the vertical direction according to the input from the driver 16. .

Also, the driver 16 can stop the analysis by pressing the "measurement stop" button 408 in FIG. 4(a) during the measurement. In-vehicle device 40 transmits an instruction to stop measurement to analysis device 50 in response to pressing of “stop measurement” button 408 .

In step S<b>1004 , analysis device 50 transmits the analysis result of component analyzer 56 to in-vehicle device 40 . In step S<b>1005 , the in-vehicle device 40 presents the acquired analysis result to the driver 16 . For example, the in-vehicle device 40 displays an analysis result output screen 410 via the display unit 46, as shown in FIG. 4B. The output screen 410 includes a message 412 to the effect that the analysis has ended and an analysis result 414 . Note that the in-vehicle device 40 may output the analysis result to the printer 90 . In this case, the printer 90 can print the received analysis results.

In step S<b>1006 , the analysis device 50 transmits the analysis result of the component analyzer 56 to the transfer destination terminal 34 . Note that step S1006 may be executed in parallel with step S1004, or may be executed after receiving a confirmation input from the driver 16 after step S1005. In step S<b>1007 , the destination terminal 34 presents the acquired analysis result to the administrator 36 .

In step S1008, the destination terminal 34 acquires the unloading information about the unloading place where the scrap S is unloaded. For example, the manager 36 may determine the unloading location based on the presented analysis results and enter the unloading information into the destination terminal 34 . In step S<b>1009 , the destination terminal 34 transmits the acquired unloading information to the in-vehicle device 40 .

In step S<b>1010 , the in-vehicle device 40 presents the acquired unloading information to the driver 16 . The in-vehicle device 40 displays, for example, an unloading information output screen 420 via the display unit 46, as shown in FIG. 4(c). The output screen 420 includes an instruction message 422 regarding the unloading site where the unloading of step S is performed, and a map image 424 indicating the location of the unloading site. For example, the map image 424 may highlight and display the unloading site (here, the second unloading site P2).

Note that the processing flow of the analysis system 1 is not limited to the above example. For example, the management device 32 may intervene in exchanges between the analysis device 50 and the transfer destination terminal 34 . Also, instead of the destination terminal 34, the management device 32 may receive the analysis result and transmit it to the on-vehicle device 40 of the unloading information. Note that the management device 32 and the destination terminal 34 may determine the unloading information from the analysis results using a reference table or an arbitrary algorithm, and in this case step S1005 may be omitted.

Transmission of the analysis result from the analysis device 50 to the in-vehicle device 40 may be omitted. In this case, the destination terminal 34 may transmit the analysis result to the analysis device 50 together with the unloading information. Alternatively, the in-vehicle device 40 or the analysis device 50 may determine the unloading information from the analysis results using a reference table or an arbitrary algorithm without going through the destination facility 30 . Any other processing flow can be used.

According to the analysis system 1 of the above-described embodiment, the cargo can be analyzed while the cargo is being transported by movably installing the analyzer on the loading platform 14 . Therefore, the analysis system 1 does not require a pretreatment process before departure and an analysis process after arrival at the destination facility 30 . In addition, before the vehicle 10 arrives at the destination facility 30, the destination facility 30 can determine in advance unloading information such as the unloading location of the cargo based on the analysis results acquired during the transportation. can. Unloading information can also be obtained by the in-vehicle device 40 before the driver 16 arrives at the destination facility 30 . Therefore, the analysis system 1 does not require the step of determining the unloading place after arriving at the destination facility 30 . In this way, the analysis system 1 can improve the efficiency of cargo analysis work.

Further, in the conventional analysis at the time of unloading, for example, a hand-type fluorescent X-ray spectrometer was used for spot sampling and analysis. For this reason, there have been cases where the detection of trace amounts of impurities mixed in has failed, and the quality has deteriorated. However, according to the analysis system 1 according to the present embodiment, the component analyzer 56 can be moved two-dimensionally on the loading platform 14, so the cargo can be analyzed in the front, rear, left, and right directions (in the X and Y directions in the figure). ) can be performed exhaustively. As a result, it is possible to suppress the contamination of impurities, so that an improvement in quality can be expected.

The analysis system 1 may include a presentation device that acquires analysis information based on analysis by an analyzer provided on the carrier 14 and presents the analysis information to the driver 16 and the manager 36 . The analysis information includes analysis results of cargo, unloading information based on the analysis results, and the like. For example, the destination terminal 34, the in-vehicle device 40, the printer 90, etc. can be used as the presentation device. The presentation device can acquire, as analytical information, the unloading information about the unloading place where the unloading of the cargo is to be carried out based on the analysis result of the cargo, and present the unloading information.

In the analysis system 1 of this embodiment, the detection accuracy of the detection unit 56a may be limited due to vibrations that occur while the vehicle 10 is running. Therefore, the control unit 52 can adjust the measurement conditions of the detection unit 56a so that the accuracy and sensitivity are not unnecessarily high in light of external factors such as vibration.

<Modification>
In the above embodiment, the component analyzer 56 supported by the moving mechanism 54 on the carrier 14 includes the detection unit 56a and the analysis unit 56b. good. The position of the analysis unit 56b is not particularly limited.

For example, the control unit 52 may perform the function of the analysis unit 56b by acquiring the detection result of the detection unit 56a and analyzing the detection result.

In the above embodiment, it was explained that the in-vehicle device 40 and the analysis device 50 each include a control unit and a storage unit, but a common control unit and storage unit may be used. For example, the processing unit 44 of the in-vehicle device 40 can also function as the control unit 52 of the analysis device 50 described above. The storage unit 48 of the in-vehicle device 40 can also function as the storage unit 58 of the analysis device 50 described above.

Although the rack and pinion mechanism was described as the mechanism of the moving mechanism 54 in the above embodiment, the moving mechanism 54 is not limited to this. For example, a timing belt or a ball screw may be used to convert the rotary motion of the drive source into linear motion, or a drive source that provides linear motion may be used, or any other mechanism may be used. may be used.

In the above-described embodiment, the moving mechanism 54 moves the component analyzer 56 in three directions: the front-rear direction, the left-right direction (vehicle width direction), and the vertical direction. May be omitted.
