  Hereinafter, with reference to the drawings, a storage / delivery work support system 100 according to an embodiment of the present invention will be described.

  First, with reference to FIG. 1, the storage area 6 in which the loading / unloading work support system 100 is used will be described.

  The storage area 6 is, for example, a warehouse. In the storage area 6, a plurality of racks 7 that store the articles 11 are installed. A mark 8 is set at a predetermined position in the storage area 6.

  The storage area 6 includes a carrier passage 3a in which the cart 4 as a carrier moves and a worker passage 3b in which the worker 1 moves.

  The platform passage 3a is formed to have a width that allows the operator 1 to push the cart 4 to pass therethrough. The cart 4 can be temporarily stopped in the loading passage 3a. Not only the cart 4 but also the worker 1 can pass through the carrier passage 3a.

  The width of the worker passage 3b is smaller than that of the carrier passage 3a. The cart 4 does not enter the worker passage 3b, and only the worker 1 passes through. The worker passage 3b has a plurality of connection passages 3c intersecting with the luggage carrier passage 3a, and a plurality of parallel passages 3d provided in parallel with the luggage carrier passage 3a and connecting the connection passages 3c. The worker passage 3b is formed in a lattice shape in which the connection passage 3c and the parallel passage 3d form an intersection.

  The mark 8 is provided at the intersection of the parallel passage 3d and the connection passage 3c formed between the racks 7. The mark 8 is installed on the ceiling portion of each intersection so that it can be easily seen by the worker 1 and does not interfere with the warehousing / unloading work.

  When storing the article 11, the worker 1 who has stopped the cart 4 at the stop position of the platform passage 3a takes out the article 11 from the cart 4, enters the worker passage 3b from the connection passage 3c, and stores the article 11. After carrying out, the process returns from the connection passage 3c to the cart 4 on the loading passage 3a. On the other hand, when the article 11 is to be unloaded, the worker 1 who has stopped the cart 4 at the stop position of the loading platform passage 3a enters the worker passage 3b from the connection passage 3c, exits the article 11, and then connects. The articles 11 are returned from the passage 3c to the cart 4 on the loading platform passage 3a.

  At this time, the connection passage 3c through which the worker 1 enters the worker passage 3b and the connection passage 3c through which the worker 1 returns to the platform passage 3a may be the same or different. . After returning to the cart 4, the worker 1 pushes and moves the cart 4 to the next stop position.

  Next, with reference to FIG. 1 to FIG. 4, an overall configuration of the warehousing / unloading work support system 100 will be described.

  As shown in FIG. 1, a loading / unloading work support system 100 includes a mobile terminal 2 used by a worker 1 during loading / unloading work, a support device 5 that executes various processes for supporting loading / unloading work, Have.

  The loading / unloading work support system 100 supports loading / unloading work of a plurality of articles 11 by the worker 1 in the storage area 6. Specifically, the loading / unloading work support system 100 is based on the shortest route to reach the loading / unloading target article 11 during the loading / unloading work in which the worker 1 loads / unloads the article 11 into / from the storage area 6. Then, the instruction of the loading / unloading work is displayed on the mobile terminal 2 carried by the worker 1.

  The mobile terminal 2 is a smartphone or a tablet computer. As illustrated in FIG. 2, the mobile terminal 2 includes a ROM (Read Only Memory) 21, a CPU (Central Processing Unit) 22 that controls each unit according to various control programs stored in the ROM 21, and a work area of the CPU 22. A RAM (Random Access Memory) 23 is provided. The ROM 21, the CPU 22, the RAM 23, and the components described later are connected by the internal bus 24.

  Further, the ROM 21, the CPU 22, and the RAM 23 present a map of the entire storage area 6, and a work instruction information such as a mark 8 for guiding the worker 1 to the target article 11 of the warehousing / leaving work and a route to the mark 8. Functions as a processing unit that performs the processing described later.

  The mobile terminal 2 includes a communication unit 25, a display unit 26, an input unit 27, a voice output unit 28, and a storage unit 29.

  The communication unit 25 wirelessly connects the mobile terminal 2 to the network 9.

  The display unit 26 is, for example, a liquid crystal display (LCD), and displays work instruction information transmitted from the support device 5 described later by an LCD driver (not shown) that activates the LCD.

  The input unit 27 is a touch panel configured by combining the display unit 26 and a contact detection sensor (not shown) for the display area of the display unit 26. The input unit 27 receives an operation from the worker 1 such as selection of a work instruction number and input that the target article 11 has been stored or unloaded during the warehousing or unloading work.

  The audio output unit 28 has a circuit for converting digital data into audio and a speaker (not shown). The voice output unit 28 outputs the work instruction information such as the mark 8 for guiding the target article 11 and the route to the mark 8 by voice based on the work instruction information transmitted from the support device 5.

  The storage unit 29 stores the work instruction information transmitted from the support device 5. As the storage unit 29, an HDD (Hard Disk Drive), an SSD (Solid State Drive), or the like can be used.

  The storage unit 29 may store a program for executing a process for displaying the work instruction information transmitted from the support device 5 on the display unit 26.

  With the above configuration, the mobile terminal 2 receives the work instruction information regarding the article 11 that is the target of the warehousing / unloading work from the support device 5 via the communication unit 25, and displays the work instruction information on the display unit 26. Alternatively, the voice output unit 28 outputs the voice.

  As shown in FIG. 3, the support device 5 includes a ROM 51, a CPU 52 that controls each unit according to various control programs stored in the ROM 51, and a RAM 53 as a work area of the CPU 52. The ROM 51, the CPU 52, the RAM 53, and the components described later are connected by an internal bus 54.

  The ROM 51, the CPU 52, and the RAM 53 function as the shortest path calculation unit 55 that executes various processes for supporting the loading / unloading work of the article 11. Details of the processing executed by the support device 5 will be described later.

  The support device 5 includes a communication unit 56, an input unit 57, a display unit 58, and a storage unit 59.

  The communication unit 56 wirelessly connects the support device 5 to the network 9.

  The input unit 57 is a keyboard, a mouse, or the like, and receives various setting operations and registration operations for designating the target article 11 for entering or leaving. Examples of the information input in the input unit 57 include information for designating the article 11 that is the target of the loading / unloading operation.

  When the information for identifying the article 11 is attached to the article 11 by an identification medium such as an RFID tag, a bar code, a two-dimensional code or the like, the input unit 57 includes a reading device for reading these.

  The display unit 58 is, for example, a liquid crystal display (LCD), and is a necessary item for an operation for selecting the article 11 that is the target of the warehousing / unloading operation, various setting operations necessary for performing the warehousing / unloading operation, and the like. Is displayed.

  The storage unit 59 has a map information storage area 59A and a storage location information storage area 59B as virtual areas. As the storage unit 59, an HDD, SSD, or the like can be used. The map information storage area 59A and the storage location information storage area 59B may be prepared separately from the storage section 59 as independent storage sections.

  The map information storage area 59A stores the map information of the entire storage area 6 and the position information of the plurality of marks 8 set in the storage area 6.

  An identification ID for identifying the article 11 is attached to all the articles 11 stored in the storage area 6. In the storage location information storage area 59B, the identification ID for identifying the article 11 and the storage location information indicating the storage location of the article 11 in the storage area 6 are stored in association with each other.

  As shown in FIG. 4, in the map of the entire storage area 6 (referred to as an area map), the passages are provided with row numbers A to D and column numbers 1 to 18. At intersections where the row passages and the column passages intersect, intersection numbers such as A1 and A2, which are combinations of row numbers and column numbers, are defined. In this embodiment, the intersection number is set as the mark 8 (see FIG. 1). Moreover, the intersection number is displayed on the mark 8 installed in the storage area 6 so that the worker 1 can visually recognize it.

  The shortest path calculation unit 55 calculates the shortest path through which the worker 1 who has stopped the cart 4 in the platform passage 3a enters the worker passage 3b from the connection passage 3c and stores or leaves a plurality of articles 11. Specifically, the shortest route calculation unit 55 calculates the shortest route for loading or unloading the plurality of articles 11 targeted by the work instruction information selected by the worker 1. First, it is assumed that the shortest path calculation unit 55 has stopped the cart 4 at the stop position on the loading platform passage 3a facing all the connection passages 3c, and performs work for loading or unloading a plurality of articles 11 from the stop position of the cart 4. Person 1 calculates all the routes that the person 1 travels. The shortest route calculation unit 55 compares the calculated movement distances of the worker 1 on all the calculated routes, and determines the route having the shortest movement distance as the shortest route.

  In the example shown in FIG. 4, a work instruction for storing or leaving 30 articles 11 in the storage area 6 is executed.

  First, the worker 1 stops the cart 4 at the intersection A1. The worker 1 proceeds from the intersection A1 through the connection passage 3c toward the intersection B1. The worker 1 stores or leaves one article 11 on the way, and then returns to the cart 4 stopped at the intersection A1 by returning the connection passage 3c.

  Subsequently, the worker 1 pushes the cart 4 from the intersection A1 to proceed along the platform passage 3a and stop at the intersection A6. The worker 1 proceeds from the intersection A6 through the connection passage 3c toward the intersections B6 and C6. The worker 1 enters or exits 25 articles 11 on the way, exits from the intersection A12 to the loading platform passage 3a, and returns to the cart 4 stopped at the intersection A6.

  Subsequently, the worker 1 pushes the cart 4 from the intersection A6 to advance along the platform passage 3a and stop at the intersection A16. The worker 1 proceeds from the intersection A16 through the connection passage 3c toward the intersection B16. The worker 1 enters or leaves the three articles 11 on the way, and then returns to the cart 4 stopped at the intersection A16 by returning to the connection passage 3c.

  Subsequently, the worker 1 pushes the cart 4 from the intersection A16, advances along the platform passage 3a, and stops at the intersection A17. The worker 1 proceeds from the intersection A17 through the connection passage 3c toward the intersection B17. The worker 1 enters or leaves one article 11 on the way, and then returns to the cart 4 stopped at the intersection A17 by returning the connection passage 3c.

  The worker 1 can enter or exit all the articles 11 by following the above route.

  However, in the example shown in FIG. 4, the worker 1 stops the cart 4 at the intersection A6, enters the worker passage 3b, and then returns to the intersection A6 again. The goods 11 are put in or taken out. Therefore, even if the distance is the shortest, there is a possibility that the worker 1 needs to move with a large number of articles 11, and in order for the worker 1 to perform the work of loading or unloading the articles 11, It is not always efficient. Therefore, in the loading / unloading work support system 100, as will be described below, a work area 10 described below from the time when the worker 1 leaves the cart 4 to the loading / unloading of the article 11 and the return of the article 11 is divided into a plurality of areas. Calculate the shortest path.

  Next, with reference to FIG. 5 to FIG. 7, a loading / unloading work support method using the loading / unloading work support system 100 will be described.

  The support device 5 repeatedly executes the routine shown in FIG. 5 at regular time intervals of, for example, 10 milliseconds. Here, with reference to FIG. 6 and FIG. 7 together, a case where a plurality of articles 11 are stored in or out of the storage area 6 will be described as an example.

  In step S11, the shortest route calculation unit 55 calculates the shortest route. Specifically, the shortest route calculation unit 55 calculates the shortest route for loading or unloading the plurality of articles 11 targeted by the work instruction information selected by the worker 1. First, it is assumed that the shortest path calculation unit 55 has stopped the cart 4 at the stop position on the loading platform passage 3a facing all the connection passages 3c, and performs work for loading or unloading a plurality of articles 11 from the stop position of the cart 4. Person 1 calculates all the routes that the person 1 travels. The shortest route calculation unit 55 compares the calculated movement distances of the worker 1 on all the calculated routes, and determines the route having the shortest movement distance as the shortest route.

  In step S12, the shortest path calculation unit 55 creates a work area 10 for each stop position of the cart 4 with each position where the cart 4 has stopped as a starting point. Specifically, as shown in FIG. 6, the shortest route calculation unit 55 sets a region (region indicated by a broken line) including all routes starting from the cart 4 and returning to the cart 4 as the work region 10. Here, the length in the direction of the parallel passage 3d (horizontal direction) in the work area 10 is W, and the length in the direction of the connection passage 3c (longitudinal length) is D.

  In step S13, the shortest path calculation unit 55 determines whether the aspect ratio (W / D) of the work area 10 is larger than a predetermined value. When it is determined in step S13 that the aspect ratio (W / D) of the work area 10 is larger than the predetermined value, the process proceeds to step S15. In step S13, when it is determined that the aspect ratio (W / D) of the work area 10 is not larger than the predetermined value, that is, the predetermined value or less, the process proceeds to step S14 and exits the process.

  Here, the predetermined value used in step S13 is set to 0.5, for example. This predetermined value is set to an appropriate value based on the shape and size of the storage area 6.

  In the example shown in FIG. 6, the aspect ratio (W / D) of the work area 10 is larger than 0.5. Therefore, as a result of the determination in step S13, the process proceeds to step S15.

  As described above, the shortest path calculating unit 55 sets the aspect ratio (W / D) of the horizontal length in the direction of the parallel passage 3d and the vertical length in the direction of the connection passage 3c to be equal to or less than a preset predetermined ratio. The shortest path is calculated so that

  Here, when the work area 10 based on the shortest route calculated in step S11 is relatively large, there is a possibility that the number of articles 11 that the worker 1 enters or leaves will increase. Therefore, in steps S15 to S17, the work area 10 is divided into smaller parts by utilizing the number of the connecting passages 3c.

  Specifically, in step S15, the shortest route calculation unit 55 determines whether or not the number of connection paths 3c included in the work area 10 is greater than a predetermined number. When it is determined in step S15 that the number of the connecting passages 3c included in the work area 10 is larger than the predetermined number, the process proceeds to step S16. When it is determined in step S15 that the number of the connection passages 3c included in the work area 10 is not more than the predetermined number, that is, the predetermined number or less, the process proceeds to step S14 and exits the process.

  Here, the predetermined number used in step S15 is set to 4, for example. This predetermined number is set in relation to the predetermined value used in step S13. Specifically, when the vertical length D of the work area 10 is the vertical length of the storage area 6 (when it is the maximum), the work area 10 set based on the predetermined value in step S13. The predetermined number is set so that the range is shorter than the horizontal length of the.

  In the example shown in FIG. 6, the number of the connecting passages 3c included in the work area 10 is 9, which is larger than 4 which is set as the predetermined number. Therefore, as a result of the determination in step S15, the process proceeds to step S16.

  In step S16, the shortest route calculation unit 55 creates the work area 10 so that the predetermined number of connection passages 3c used in step S15 are included. Specifically, as shown in FIG. 6, the work area 10 is divided up to the area including the four connection passages 3c (the area indicated by the chain double-dashed line).

  In step S17, the shortest route calculation unit 55 calculates the shortest route for the worker 1 to store or leave the article 11 within the work area 10 set in step S16, as in step S11.

  In this way, the shortest route calculation unit 55 sets the shortest route through which the worker 1 enters and leaves the plurality of articles 11 using the cart 4 through the platform passage 3a and the worker passage 3b within a predetermined number. The calculation is performed within the range of the connection passage 3c.

  As a result, a path that maximizes the area including the predetermined number of connection passages 3c is formed. Therefore, since the work area 10 is divided into smaller parts by utilizing the number of the connecting passages 3c, it is possible to prevent the work area 10 from becoming large and increasing the number of articles 11 that the worker 1 enters or leaves. Therefore, the worker 1 can be assisted so that the plurality of articles 11 can be efficiently put in and out.

  On the other hand, in step S14, since the work area 10 based on the shortest path calculated in step S11 is divided into sufficiently small parts, the shortest path is used as it is.

  As described above, when the aspect ratio (W / D) of the work area 10 is larger than the predetermined ratio, the shortest route calculation unit 55 calculates the shortest route within a predetermined number of passages, and the aspect ratio (W / D). If / D) is less than or equal to the predetermined ratio, the shortest route calculated based on the predetermined ratio is used even if the number of passages exceeds the predetermined number.

  Then, by repeating the routine shown in FIG. 5, the shortest path calculation unit 55 also calculates the shortest path for the articles 11 stored in the remaining storage area 6. As a result, as shown in FIG. 7, a plurality of routes that maximize the area including the four connection passages 3c are created. That is, the shortest path calculation unit 55 allows the worker 1 who has stopped the cart 4 in the loading platform passage 3a facing the connection passage 3c to enter or leave the plurality of articles 11 by entering the worker passage 3b from the connection passage 3c. The shortest route for loading and unloading a plurality of articles 11 is calculated by combining a plurality of routes for returning to the cart 4.

  The number of the connecting passages 3c included in the work area 10 in step S15 is larger than the predetermined number without determining whether the aspect ratio (W / D) of the work area 10 in step S13 is larger than the predetermined value. Only the determination as to whether or not it may be performed. In this case, the shortest route is calculated based on only the number of the connecting passages 3c included in the work area 10.

  Further, the shortest route calculation unit 55 calculates a route in a range in which the vertical length D of the work area 10 does not exceed a predetermined upper limit value of the vertical length in the direction of the worker passage 3b set in advance. Good. In this case, since the vertical length D of the work area 10 may become too long, the storage area 6 is divided so that the vertical length does not exceed a predetermined upper limit value.

  Next, with reference to FIG. 8 to FIG. 9J, a specific example of the support of the storage / delivery work of the article 11 to the worker 1 by the storage / delivery work support system 100 is described.

  The storage area 6 is divided into a plurality of divided areas 6a in which individual color information is set. Here, as an example, a case will be described in which the worker 1 performs the leaving work in the divided area 6a in which the red color information in the storage area 6 is set. The case where the worker 1 leaves the article 11 will be described, but the same applies to the case where the article 11 is put in.

  First, the worker 1 selects the work instruction information for the leaving work. When the worker 1 completes the selection of the work instruction information, the worker 1 enters the divided area 6a from the intersection A1 while pushing the cart 4.

  When the worker 1 operates the mobile terminal 2 to log in to the support device 5, the search screen shown in FIG. 9A is displayed on the display unit 26. A search setting area 31 for inputting search conditions is set on the left side of the search screen, and a work instruction information area 32 for displaying work instruction information matching the search conditions is set on the right side of the screen. . Below the work instruction information area 32, a work start point selection switch 33 is provided.

  In the search setting area 31, the worker 1 selects whether to perform a warehousing work or a warehousing work, an area code for the worker 1 to perform a warehousing or warehousing work, a selection as to whether or not a work has started, and a work instruction. You can enter the number manually.

  The screen shown in FIG. 9A is input by the worker 1 by operating the mobile terminal 2 so as to perform the leaving work in a state where the unstarted state is currently performed in the divided area 6a in which the red color information of the first floor is set. It is in a state. At the bottom of the search setting area 31, as a search result, it is displayed that three pieces of work instruction information match the search conditions.

  In the work instruction information area 32, the work instruction numbers, statuses, and area codes of the three pieces of work instruction information that match the search conditions are displayed. The worker 1 selects any work instruction information. Here, the worker 1 has selected the first work instruction number “00030000109”. On the display unit 26, the selected work instruction information is highlighted.

  The work start point selection switch 33 is for selecting the starting point of the route calculated by the shortest route calculation unit 55 from a plurality of points on the platform passage 3a. The work start point selection switch 33 is provided so that a plurality of work start points (here, three) can be selected.

  When the worker 1 selects the left first point selection switch 33a, the shortest route calculation unit 55 determines that the cart 4 is located at the entrance of the divided area 6a, that is, the shortest route from the state where the cart 4 is located at the intersection A1. Is calculated. When the worker 1 selects the central second point selection switch 33b, the shortest route calculation unit 55 causes the cart 4 to be located at a point where the cart 4 has advanced from the entrance of the divided area 6a by about ⅓ of the whole, that is, the intersection A4. The shortest route is calculated from the state where the cart 4 is located in the vicinity. When the worker 1 selects the third point selection switch 33c on the right side, the shortest route calculation unit 55 causes the shortest route calculation unit 55 to be located at a point where the cart 4 has advanced about 2/3 of the entire area from the entrance of the divided area 6a, that is, the intersection A8. The shortest route is calculated from the state where the cart 4 is located in the vicinity.

  In this way, by making the work start point selectable, the next storage or exit from the position close to the point where the worker 1 performed the previous storage or exit work in the divided area 6a is completed. You can start working. Therefore, the worker 1 does not have to return to the start point (for example, the intersection A1 of the entrance) every time the warehousing or unloading work is completed. Therefore, the moving distance of the worker 1 can be shortened.

  When the operator 1 selects any one of the first point selection switch 33a, the second point selection switch 33b, and the third point selection switch 33c, the shortest path calculation unit 55 executes the routine shown in FIG. 5 described above. . As a result, the worker 1 stops the cart 4 in the loading passage 3a near the point selected by the work start point selection switch 33, enters the worker passage 3b from the connection passage 3c, and stores or stores a plurality of articles 11. The shortest route for entering and leaving a plurality of articles 11 is calculated by combining a plurality of routes for warehousing and returning to the cart 4.

  In the example shown in FIG. 8, the worker 1 selects the first point selection switch 33a, and the shortest route is calculated from the state where the cart 4 is located at the entrance of the divided area 6a. A navigation screen described later is displayed on the display unit 26 on the route shown by the solid line in FIG. 8, and a data display screen described later is displayed on the display unit 26 on the route shown by the broken line.

  The display unit 26 is switched to the navigation screen shown in FIG. 9B. That is, the display unit 26 displays an instruction for the leaving operation based on the shortest route calculated by the shortest route calculation unit 55.

  As shown in FIG. 9B, on the left side of the navigation screen, a loading platform route display area 34 that displays the route information of the cart 4 is set, and on the right side, a worker route display area 35 that displays the route information of the worker 1. Is set. Thus, in the state where the navigation screen is displayed, the display unit 26 displays the route information of the cart 4 and the route information of the worker 1 based on the route information of the cart 4 at the same time with the screen divided. It

  Therefore, the worker 1 always displays the stop position of the cart 4 while moving away from the cart 4 in the worker passage 3b. You can figure out what is good.

  Further, the work instruction number selected by the worker 1 on the search screen is displayed at the upper end of the navigation screen, and the number of articles 11 to be delivered in the work area 10 is displayed at the lower right of the navigation screen. ing.
