The storage area 6 includes a platform passage 3a through which a cart 4 serving as a loading platform moves, and a worker passage 3b through which the worker 1 moves.

The loading platform passage 3a is formed to have a width that allows the worker 1 to push the cart 4 through. It is possible to temporarily stop the cart 4 in the platform passage 3a. Not only the cart 4 but also the worker 1 can pass through the loading platform passage 3a.

The worker passage 3b is narrower than the loading platform passage 3a. The cart 4 does not enter the worker passageway 3b, and only the worker 1 passes therethrough. The worker passage 3b includes a plurality of connecting passages 3c that intersect with the loading platform passage 3a, and a plurality of parallel passages 3d that are provided in parallel with the loading platform passage 3a and connecting the connecting passages 3c. The worker passage 3b is formed in a grid shape in which the connection passage 3c and the parallel passage 3d form intersections.

The mark 8 is provided at the intersection of the connecting passage 3c and the parallel passage 3d formed between the racks 7. The mark 8 is installed on the ceiling of each intersection so that it is easily visible to the worker 1 and does not interfere with the loading and unloading work.

When storing the article 11, the worker 1 stops the cart 4 at the stop position of the loading platform passage 3a, takes the article 11 from the cart 4, enters the worker passage 3b from the connecting passage 3c, and stores the article 11. After doing so, it returns to the cart 4 on the loading platform passage 3a from the connecting passage 3c. On the other hand, when taking out the goods 11, the worker 1 stops the cart 4 at the stop position of the loading platform passage 3a, enters the worker passage 3b from the connecting passage 3c, takes out the goods 11, and then connects the The cart 4 is returned from the passage 3c to the cart 4 on the platform passage 3a, and the articles 11 are loaded thereon.

At this time, the connection passage 3c that the worker 1 passes through when entering the worker passage 3b and the connection passage 3c that the worker 1 passes through when returning to the loading platform passage 3a may be the same or different. . After returning to the cart 4, the worker 1 pushes the cart 4 to the next stop position.

Next, with reference to FIGS. 1 to 4, the overall configuration of the warehouse loading/unloading work support system 100 will be described.

Specifically, the warehousing/retrieval work support system 100 performs warehousing/retrieval work based on the shortest route to reach the article 11 to be warehousing/retrieval when the worker 1 is warehousing/retrieving the article 11 into or out of the storage area 6. Then, instructions for loading and unloading work are displayed on the mobile terminal 2 carried by the worker 1.

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

In addition, the ROM 21, CPU 22, and RAM 23 present a map of the entire storage area 6, a mark 8 for guiding the worker 1 to the target article 11 for warehousing and unloading work, and work instruction information such as a route to the mark 8. It functions as a processing unit that performs the processing described below.

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

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

The display unit 26 is, for example, a liquid crystal display (LCD), and displays work instruction information transmitted from the support device 5, which will be described later, by an LCD driver (not shown) that starts 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 a display area of the display unit 26. The input unit 27 receives operations from the worker 1, such as selecting a work instruction number and inputting that the target article 11 has been stored or taken out, during warehousing or unloading work.

The audio output unit 28 includes a circuit that converts digital data into audio and a speaker (not shown). Based on the work instruction information transmitted from the support device 5, the audio output unit 28 outputs work instruction information such as the landmark 8 for guiding to the target article 11 and the route to the landmark 8 in the form of voice.

The storage unit 29 stores 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 processing for displaying work instruction information transmitted from the support device 5 on the display unit 26.

With the above configuration, the mobile terminal 2 receives work instruction information regarding the article 11 to be warehoused and unloaded from the support device 5 via the communication unit 25, and displays the work instruction information on the display unit 26. Or, the audio output unit 28 outputs the audio.

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

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

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

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

The input unit 57 is a keyboard, a mouse, etc., and accepts various setting operations and registration operations for specifying the target article 11 to be warehoused or discharged. The information inputted in the input unit 57 includes information for specifying the article 11 to be subjected to loading/unloading work.

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

The display unit 58 is, for example, a liquid crystal display (LCD), and displays necessary information such as operations for selecting the article 11 to be loaded and unloaded, and various setting operations necessary for carrying out the loading and unloading operation. Display.

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 unit 59 as independent storage units.

Map information of the entire storage area 6 and position information of a plurality of landmarks 8 set in the storage area 6 are stored in the map information storage area 59A.

All the articles 11 stored in the storage area 6 are given identification IDs for identifying the articles 11. In the storage location information storage area 59B, an identification ID for identifying the article 11 and 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 a map of the entire storage area 6 (referred to as an area map), the aisles are assigned row numbers A to D and column numbers 1 to 18. Intersection numbers such as A1 and A2, which are combinations of row numbers and column numbers, are defined at intersections where row passages and column passages intersect. In this embodiment, the intersection number is set as the landmark 8 (see FIG. 1). Furthermore, an intersection number is displayed on a marker 8 installed in the storage area 6 so that the worker 1 can see it.

The shortest route calculation unit 55 calculates the shortest route for the worker 1 who has stopped the cart 4 on the platform passage 3a to enter the worker passage 3b from the connection passage 3c and to store or take out the plurality of articles 11. Specifically, the shortest route calculation unit 55 calculates the shortest route for storing or unloading the plurality of articles 11 that are targets of the work instruction information selected by the worker 1. First, assuming that the cart 4 is stopped at a stop position on the loading platform passage 3a facing all the connection passages 3c, the shortest path calculation unit 55 performs an operation for loading or unloading a plurality of articles 11 from the stop position of the cart 4. All routes taken by person 1 are calculated. The shortest route calculation unit 55 compares the travel distance of the worker 1 on all the calculated routes, and determines the route with the shortest travel distance as the shortest route.

The example shown in FIG. 4 is for executing a work instruction to store or take out 30 items 11 in the storage area 6.

First, the worker 1 stops the cart 4 at the intersection A1. The worker 1 proceeds from the intersection A1 toward the intersection B1 along the connecting passage 3c. After the worker 1 stores or takes out one article 11 along the way, the worker 1 returns along the connecting path 3c and returns to the cart 4 stopped at the intersection A1.

Subsequently, the worker 1 pushes the cart 4 from the intersection A1, proceeds along the platform passage 3a, and stops at the intersection A6. The worker 1 proceeds from the intersection A6 toward the intersections B6 and C6 along the connecting path 3c. After loading or unloading the 25 articles 11 along the way, the worker 1 exits from the intersection A12 to the 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, proceeds along the platform passage 3a, and stops at the intersection A16. The worker 1 proceeds from the intersection A16 toward the intersection B16 along the connecting path 3c. After storing or unloading the three articles 11 on the way, the worker 1 returns along the connecting path 3c and returns to the cart 4 stopped at the intersection A16.

Subsequently, the worker 1 pushes the cart 4 from the intersection A16, proceeds along the platform passage 3a, and stops at the intersection A17. The worker 1 proceeds from the intersection A17 toward the intersection B17 along the connecting path 3c. After the worker 1 stores or takes out one article 11 along the way, the worker 1 returns along the connecting path 3c and returns to the cart 4 stopped at the intersection A17.

By following the above route, the worker 1 can store or take out all the articles 11.

However, in the example shown in FIG. 4, the worker 1 stops the cart 4 at the intersection A6, enters the worker path 3b, and returns to the intersection A6 again. The article 11 is put in or taken out. Therefore, even if the distance is the shortest, there is a risk that the worker 1 will have to move with many articles 11, and in order for the worker 1 to carry out the work of storing or unloading the articles 11, It cannot necessarily be said that it is efficient. Therefore, in the warehousing and retrieval work support system 100, as will be described next, the work area 10, which will be described later, is divided into a plurality of sections from when the worker 1 leaves the cart 4 to when the worker 1 enters or unloads the article 11 and returns. Calculate the shortest path.

Next, a method for supporting loading and unloading operations using the loading and unloading operation support system 100 will be described with reference to FIGS. 5 to 7.

The support device 5 repeatedly executes the routine shown in FIG. 5 at regular intervals of, for example, every 10 milliseconds. Here, with reference to FIGS. 6 and 7, a case where a plurality of articles 11 are stored in or taken 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 storing or unloading the plurality of articles 11 that are targets of the work instruction information selected by the worker 1. First, assuming that the cart 4 is stopped at a stop position on the loading platform passage 3a facing all the connection passages 3c, the shortest path calculation unit 55 performs an operation for loading or unloading a plurality of articles 11 from the stop position of the cart 4. All routes taken by person 1 are calculated. The shortest route calculation unit 55 compares the travel distance of the worker 1 on all the calculated routes, and determines the route with the shortest travel 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, starting from each position where the cart 4 has stopped. Specifically, as shown in FIG. 6, the shortest route calculating unit 55 sets the area (the area indicated by the broken line) including all the routes from the cart 4 to the cart 4 again as the work area 10. Here, the length (horizontal length) of the parallel passage 3d in the working area 10 is W, and the length (vertical length) of the connection passage 3c 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. If 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 moves to step S15. If it is determined in step S13 that the aspect ratio (W/D) of the work area 10 is not greater than the predetermined value, that is, it is less than or equal to the predetermined value, the process proceeds to step S14 and exits from 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 greater than 0.5. Therefore, as a result of the determination in step S13, the process moves to step S15.

In this way, the shortest path calculation unit 55 determines that the aspect ratio (W/D) of the horizontal length in the parallel path 3d direction and the vertical length in the connecting path 3c direction is equal to or less than a predetermined ratio. Calculate the shortest path so that

Here, if 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 stores or takes out from the warehouse increases. Therefore, in steps S15 to S17, the work area 10 is divided into smaller pieces using the number of connection passages 3c.

Specifically, in step S15, the shortest path calculation unit 55 determines whether the number of connection passages 3c included in the work area 10 is greater than a predetermined number. If it is determined in step S15 that the number of connection passages 3c included in the work area 10 is greater than the predetermined number, the process moves to step S16. If it is determined in step S15 that the number of connection passages 3c included in the work area 10 is not more than the predetermined number, that is, it is less than or equal to the predetermined number, the process moves 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 length D in the vertical direction of the work area 10 is the length in the vertical direction of the storage area 6 (maximum), the work area 10 is 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.

In the example shown in FIG. 6, the number of connection passages 3c included in the work area 10 is nine, which is greater than the predetermined number of four. Therefore, as a result of the determination in step S15, the process moves to step S16.

In step S16, the shortest path calculation unit 55 creates the work area 10 so as to include the predetermined number of connection passages 3c used in step S15. Specifically, as shown in FIG. 6, the work area 10 is divided into areas including the four connection passages 3c (areas indicated by two-dot chain lines).

In step S17, the shortest path calculation unit 55 calculates the shortest path for the worker 1 to store or take out the article 11 within the work area 10 set in step S16, similarly to step S11.

In this way, the shortest path calculation unit 55 calculates the shortest path for the worker 1 to take in and out the plurality of articles 11 using the cart 4 through the loading platform path 3a and the worker path 3b within a predetermined number of items set in advance. The calculation is performed within the range of the connection passage 3c.

As a result, a route is formed whose maximum area includes a predetermined number of connection passages 3c. Therefore, since the work area 10 is divided into small pieces using the number of connecting passages 3c, it is possible to prevent the work area 10 from becoming large and the number of articles 11 that the worker 1 enters or takes out from the warehouse from increasing. Therefore, it is possible to support the worker 1 in efficiently loading and unloading a plurality of articles 11.

On the other hand, in step S14, since the work area 10 based on the shortest route calculated in step S11 has been divided into sufficiently small pieces, the shortest route is used as is.

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

Then, by repeating the routine shown in FIG. 5, the shortest route calculation unit 55 calculates the shortest route for the remaining articles 11 stored in the storage area 6. As a result, as shown in FIG. 7, a plurality of routes are created whose maximum area includes four connection passages 3c. That is, the shortest path calculation unit 55 determines that the worker 1 who has stopped the cart 4 on the platform passage 3a facing the connection passage 3c enters the worker passage 3b from the connection passage 3c to store or take out the plurality of articles 11. 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.

Note that without determining whether the aspect ratio (W/D) of the working area 10 is greater than a predetermined value in step S13, the number of connection passages 3c included in the working area 10 in step S15 is greater than the predetermined number. It is also possible to only determine whether or not. In this case, the shortest route is calculated based only on the number of connection passages 3c included in the work area 10.

Further, the shortest route calculation unit 55 calculates a route within a range in which the length D of the work area 10 in the vertical direction does not exceed a predetermined upper limit value of the length in the vertical direction in the direction of the worker path 3b. Good too. In this case, there is a risk that the length D in the vertical direction of the work area 10 will become too long, so the storage area 6 is divided to prevent the length in the vertical direction from exceeding a predetermined upper limit.

Next, with reference to FIGS. 8 to 9J, a specific example of how the warehousing/unloading work support system 100 supports the worker 1 in warehousing or unloading the articles 11 will be described.

The storage area 6 is divided into a plurality of divided areas 6a, each of which has separate color information set therein. Here, as an example, a case will be described in which the worker 1 performs the shipping work in the divided area 6a in which the red color information is set in the storage area 6. Although the case where the worker 1 takes out the article 11 will be described, the same applies to the case where the article 11 is put in the warehouse.

First, the worker 1 selects work instruction information for shipping work. After completing the selection of 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 is set on the right side of the screen for displaying work instruction information that matches the search conditions. . A work start point selection switch 33 is provided below the work instruction information area 32.

In the search setting area 31, worker 1 can select whether to carry out warehousing work or warehousing work, select the area code in which worker 1 will carry out warehousing or warehousing work, select whether or not it is an unstarted project, and work instructions. You can enter the number manually.

The screen shown in FIG. 9A is displayed when the worker 1 operates the mobile terminal 2 and inputs an instruction to perform the unloading work that is currently unstarted in the divided area 6a on the first floor where the red color information is set. 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.

The work instruction information area 32 displays the work instruction number, status, and area code of three items of work instruction information that match the search conditions. The worker 1 selects one of the work instruction information. Here, worker 1 has selected the first work instruction number "0003000109." On the display section 26, the selected work instruction information is highlighted.

The work start point selection switch 33 is used to select the starting point of the route calculated by the shortest route calculating section 55 from a plurality of points on the loading platform passage 3a. The work start point selection switch 33 is provided so that a plurality of (three in this case) work start points can be selected.

When the worker 1 selects the first point selection switch 33a on the left side, the shortest route calculation unit 55 calculates the shortest route from the state where the cart 4 is located at the entrance of the divided area 6a, that is, the state where the cart 4 is located at the intersection A1. Calculate. When the worker 1 selects the second point selection switch 33b in the center, the shortest route calculation unit 55 determines that the cart 4 is located at a point about 1/3 of the way from the entrance of the divided area 6a, that is, at the intersection A4. The shortest route is calculated from the state where the cart 4 is located nearby. When the worker 1 selects the third point selection switch 33c on the right side, the shortest route calculation unit 55 determines that the cart 4 is located at a point approximately 2/3 of the way from the entrance of the divided area 6a, that is, at intersection A8. The shortest route is calculated from the state where the cart 4 is located nearby.

In this way, by making it possible to select the work start point, in the divided area 6a, the next warehousing or warehousing starts from a position close to the point where the worker 1 was when the previous warehousing or warehousing work was completed. You can start working. Therefore, the worker 1 does not have to return to the starting point (for example, the entrance intersection A1) every time he completes the warehouse entry or exit work. Therefore, the moving distance of the worker 1 can be shortened.

When the worker 1 selects one of the first point selection switch 33a, the second point selection switch 33b, and the third point selection switch 33c, the shortest route calculation unit 55 executes the routine shown in FIG. 5 described above. . As a result, the worker 1 stops the cart 4 on the platform 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 the plurality of articles 11. By combining a plurality of routes for unloading and returning to the cart 4, the shortest route for loading and unloading a plurality of articles 11 is calculated.

The example shown in FIG. 8 shows a state in which the worker 1 selects the first point selection switch 33a and the shortest route is calculated from a state in which the cart 4 is located at the entrance of the divided area 6a. Note that for the route shown by the solid line in FIG. 8, a navigation screen to be described later is displayed on the display section 26, and for the route shown by the broken line, a data display screen to be described later is displayed on the display section 26.

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

As shown in FIG. 9B, a loading platform route display area 34 that displays route information for the cart 4 is set on the left side of the navigation screen, and a worker route display area 35 that displays route information for the worker 1 is set on the right side. is set. In this manner, when the navigation screen is displayed, the route information of the cart 4 and the route information of the worker 1 based on the route information of the cart 4 are displayed simultaneously on the display unit 26 by dividing the screen. Ru.

Therefore, even while the worker 1 is moving away from the cart 4 and moving along the worker path 3b, the stopping position of the cart 4 is always displayed, so that the worker 1 does not know which point he should return to after taking out the goods 11. You can figure out what's good.

In addition, the work order number selected by the worker 1 on the search screen is displayed at the top of the navigation screen, and the number of articles 11 to be delivered within the work area 10 is displayed at the bottom right of the navigation screen. ing.

The route information of the cart 4 displayed in the platform route display area 34 is the stop position information on the platform path 3a where the cart 4 is stopped. In the example shown in FIG. 9B, work instruction information for pushing the cart 4 along the platform passage 3a and stopping at the intersection A3 is displayed.

The route information of the worker 1 displayed in the worker route display area 35 is navigation information that sequentially displays the route of the worker 1 from the stop position where the cart 4 is stopped based on the stop position information of the cart 4. .
