Description

Embodiments of the present invention relate to a transport setting method, a shelf setting program, and a transport system.

In recent years, conveyance systems have been realized in distribution centers, warehouses, etc. that use automatic guided vehicles to sort articles to be conveyed. The transport system transports a transport shelf (POD) that stores articles to a station by an automatic transport vehicle. At the station, an operator or a robot picks articles from a transport shelf transported by an automatic transport vehicle and sorts the articles onto trays placed on a sorting shelf (DAS).

In conventional transport systems, the size of the opening (the area where the goods are placed) on the transport shelf cannot be changed from the initially registered state, so products are not placed in openings of rarely used sizes, and There is a problem that the occupancy rate of the frontage decreases. In addition, in conventional transportation systems, the trays of the sorting shelves (the area where items are placed) used for retrieval cannot be changed from the initial registered state. There is a problem that the value decreases.

Embodiments will be described below with reference to the drawings.
FIG. 1 is a diagram schematically showing an example of the overall configuration of a transport system 1 according to an embodiment.
In the configuration example shown in FIG. 1, the transport system 1 includes a station (work area) P, a client device 2, a sorting shelf (DAS) 3, a plurality of AGVs 7, a plurality of transport shelves (POD, AGV shelves) 8, etc. Be prepared.

The transport system 1 according to the embodiment is a system for controlling and managing the work of sorting articles to be picked from shelves in a distribution center, warehouse, or the like. The transport system 1 transports a transport shelf (POD, AGV shelf) 8 to a station P using an automated guided vehicle (AGV) 7. The conveyance system 1 controls (manages) the work of sorting articles picked from the conveyance shelves 8 to the sorting shelves (DAS) 3 at the station P.

A client device 2 is installed at the station P. At station P, an operator uses the client device 2 to perform work. Moreover, a robot may be installed at the station P. The transport system 1 controls the AGV 7. Under the control of the transport system 1, the AGV 7 transports the transport shelf 8 on which the articles are placed to the station P. At each station P, an operator or a robot picks articles on a transport shelf 8 carried by the AGV 7 and stores the picked articles on a sorting shelf (DAS) 3.

The transport system 1 causes the client device 2 installed at a station P, which is a work area, to display an article processing schedule and the like. The operator visually checks the article processing schedule etc. displayed on the client device 2 installed at the station P and performs work such as storing or picking articles. Furthermore, the transport system 1 can also stop the operation of the robot placed at the station P and allow the operator to carry out work such as storing or picking articles.

In addition, various instructions from an operator are input to the client device 2 . For example, the client device 2 receives an operation instruction indicating that the operator has completed picking an article. Further, the client device 2 receives an instruction by the operator to change the settings of the transport shelf 8 and an instruction to change the settings of the sorting shelf 3. The client device 2 supplies instructions input by the operator to the WCS 11 (see FIG. 2), which is a host device. Note that the client device 2 may be a computer installed at the station P, or may be a wireless communication terminal assigned to an operator.

Furthermore, the transport system 1 may include a plurality of cameras installed in a distribution center or warehouse where the system operates. Furthermore, one or more of the plurality of cameras may be fixed cameras, and the remaining cameras may be mobile cameras. The fixed cameras are fixed to, for example, the ceiling, walls, and the upper and side surfaces of the station P, and output photographic data of the entire warehouse where articles are processed and a predetermined area within the warehouse in real time. The photographing data includes photographing date and time data (including photographing time) and photographed image data. The photographed image data is still image data and moving image data. Further, the fixed camera may rotate up and down and left and right. By rotating the fixed camera vertically and horizontally, the warehouse can be monitored over a wide area.

DAS3 is installed at station P. The DAS 3 arranges a tray 4 that serves as an article placement area on which articles are placed (or stored). Sorted articles are placed on each tray 4 arranged in the DAS 3. In the DAS 3, the layout of the tray as an article placement area can be changed. The DAS 3 may include a terminal that reads codes and the like from articles.

The DAS 3 also includes a display D (see FIG. 11, etc.) and a button B (see FIG. 11, etc.). The display device D displays the number of articles placed on the tray 4 at the corresponding position. Button B scans the barcode of the product with a scanner or the like, and when the barcode is scanned a predetermined number of times, the button lights up or flashes. Furthermore, when the lit or blinking button B is pressed, the system is notified that the delivery has been completed. The display device D and the button B are each provided at a position corresponding to a predetermined initial position of each tray 4 arranged in the DAS 3, for example. When the layout of the tray 4 in the DAS 3 is changed, the display device D and the button B are enabled (active) or disabled (inactive) depending on the layout of the tray 4.

The AGV (automatic transport device) 7 operates based on a control signal from the WCS 11, which will be described later. For example, the AGV 7 travels toward a designated loading position and lifts up the transport shelf 8 at the designated loading position. The AGV 7 travels to the designated loading/unloading location and moves to the designated station. When the work at the station is completed, the AGV 7 transports the transport shelf 8 to the loading/unloading position, and unloads the transport shelf 8 at the unloading position. Note that the AGV 7 does not necessarily have to return the transport shelf after the work has been completed to its original position, but may return it anywhere within the shelf storage area.

The transport shelf 8 is a shelf on which articles are placed. The transport shelf 8 stands upright on four pillars, for example. The height of the bottom of the transport shelf 8 (height from the floor to the bottom of the shelf) is higher than the height of the AGV 7. Thereby, the AGV 7 can sneak under the transport shelf 8. The AGV 7 that has crawled under the shelf uses a pusher to lift the transport shelf 8 to such an extent that the tips of the columns are separated from the floor by several centimeters, and travels with the transport shelf 8 lifted. In this way, the AGV 7 transports the transport shelf 8.

The transport shelf 8 has a plurality of shelves (BIN). Each shelf tier is formed by shelf boards attached to four pillars forming the transport shelf 8. In this embodiment, some or all of the shelf boards in the transport shelf 8 may be removable. A frontage 5 is formed in each shelf in the transport shelf 8 as an article placement area for placing articles. The frontage 5 in each shelf is formed by a partition member 6, for example. The partition member 6 on the transport shelf 8 is configured to be movable in its installation position. In the transport shelf 8, the layout (size and position) of the frontage 5 in the shelf can be changed using the movable partition member 6.

For example, the partition member 6 is configured to be able to be installed or removed at a predetermined position or any position on the shelf. Further, the transport shelf 8 may be provided with a mechanism that allows the partition member 6 to move along the surface on which the articles are placed on the shelf (shelf board). Furthermore, the transport shelf 8 may be provided with a mechanism that allows the partition members 6 on the shelves (shelf boards) to move under control from the WCS 11 or the client device 2. Furthermore, the transport shelf 8 may be provided with a partition position detection section that detects the position of the partition member 6.

Further, the transport shelf 8 displays identification information (referred to as frontage identification information) for identifying the frontage at a position corresponding to each frontage 5. The frontage identification information is indicated by, for example, a code such as a bar code or a two-dimensional code displayed (written) on a recording medium such as a card. The code indicating frontage identification information (hereinafter also referred to as frontage code) is information that can be read by a code reader 28 (see FIG. 3), which is configured with a fixed camera or a mobile camera.

The transport shelf 8 has a configuration that allows the display position of the frontage code to be moved according to the position of each frontage 5 when the layout of the frontage 5 is changed. For example, the frontage code may be displayed on a medium (for example, a card) that can be set (for example, pasted) at an arbitrary position such as a shelf board or partition member 6 in the transport shelf 8. Further, the transport shelf 8 may be configured such that the display position of the frontage code moves according to the movement of the partition member 6 forming each frontage 5 (for example, following the movement of the partition member 6).

Next, the transport shelf 8 in the transport system 1 according to the embodiment will be explained.
As shown in FIG. 1, on the transport shelf 8, articles are placed in the opening 5 formed by the partition member 6. In this embodiment, in the transport shelf 8, the position of the partition member 6 is movable. The transport system 1 accepts changes in the layout of the frontage 5 in the shelves of the transport rack 8 even during operation.

The transport shelf 8 may have a structure in which the partition members 6 can be installed or removed at predetermined positions on each shelf, or may be provided with a mechanism so that the partition members 6 can be moved to arbitrary positions. When changing the position of the partition member 6 in the transport shelf 8, the display position of the frontage code is changed or the frontage code is changed in accordance with the change in the layout of the frontage 5. In addition, the WCS 11 receives changes in the layout of the frontage 5 and the frontage code of the transport shelf 8, and updates the setting information of the transport shelf 8 stored in the database 14 according to the specified layout change and change in the frontage code. .

FIG. 5 is a diagram showing an example of the layout of the frontage 5 in the shelf tier of the transport shelf 8. As shown in FIG.
FIG. 5 shows three layouts L1, L2, and L3 as examples of the layout of the frontage 5 in the shelf. Here, it is assumed that the operator changes the layout of the frontage by moving the partition member 6 on the shelf of the transport shelf 8.

The first layout L1 forms three frontages 511, 512, 513 using four partition members 6a, 6b, 6c, 6d, and a frontage code indicating frontage identification information of each frontage 511, 512, 513, respectively. Place it in the position corresponding to . In the second layout L2, two frontages 521 and 522 are formed using three partition members 6a, 6b (or 6c), and 6d, and frontage codes indicating frontage identification information of each frontage 521 and 522 are respectively associated with each other. Place it in the desired position. In the third layout L3, one frontage 531 is formed using two partition members 6a and 6d, and a frontage code indicating frontage identification information of the frontage 531 is arranged at a position corresponding to the frontage 531. In the example shown in FIG. 5, the frontage code indicating the frontage identification information is displayed (printed) on a medium such as a card, and the medium on which the frontage code is displayed is placed on a shelf or the like. .

When changing from the first layout L1 to the second layout L2, the operator removes the partition members 6b and 6c and attaches the partition member 6b (or 6c) to the position shown in FIG. As a result, the shelf changes to a second layout L2 consisting of a frontage 521 formed by the partition member 6a and the partition member 6b (or 6c), and a frontage 522 formed by the partition member 6a and the partition member 6d. be done.

When changing from the first layout L1 to the second layout L2, the operator further places the frontage code of each frontage 521, 522 at a position corresponding to each frontage. That is, the operator performs the work of arranging the frontage codes of the frontages 521 and 522 at positions corresponding to the frontages 521 and 522 of the second layout L2.
Each frontage code corresponding to the frontages 521 and 522 may be newly issued. When newly issuing each frontage code corresponding to the frontage 521 and 522, the operator places a medium displaying the newly issued frontage code at a position corresponding to each frontage 521 and 522.

Moreover, each frontage code corresponding to the frontages 521 and 522 may be an existing frontage code (the frontage code in the first layout L1). For example, the settings may be changed so that the frontage code of the frontage 511 is used as the frontage code of the frontage 521, and the frontage code of the frontage 513 (or 512) is used as the frontage code of the frontage 522. In this case, the display position of the frontage code of the frontage 521 may be the display position of the frontage code of the frontage 511 in the first layout L1, or may be moved to near the center of the frontage 512. Similarly, the display position of the frontage code of the frontage 522 may be the display position of the frontage code of the frontage 512 in the first layout L1, or may be moved to near the center of the frontage 512.

When changing from the first layout L1 (or second layout L2) to the third layout L3, the operator removes the partition members 6b and 6c. As a result, the shelf is changed to the third layout L3, which includes a frontage 531 formed by the partition member 6a and the partition member 6d. Note that the operator may change to the third layout L3 consisting of the frontage 531 by arranging the partition members 6b and 6c so as to overlap the partition member 6a or 6d.

When changing from the first layout L1 to the third layout L3, the operator further places the frontage code of the frontage 531 at a position corresponding to the frontage 531. That is, the operator performs the work of arranging the frontage code of the frontage 531 at a position corresponding to the frontage 531 of the third layout L3.
The frontage code for the frontage 531 may be newly issued. When issuing a new frontage code for the frontage 531, the operator places a medium displaying the newly issued frontage code at a position corresponding to each frontage 531.

As the frontage code of the frontage 531, an existing frontage code (the frontage code in the first layout L1) may be used. For example, the setting may be changed so that the frontage code of the frontage 531 is used as the frontage code of the frontage 512 in the first layout L1. In this case, the display position of the frontage code of the frontage 531 may be the display position of the frontage code of the frontage 512 in the first layout L1, and the frontage codes of the frontage 511 and 513 in the first layout L1 may be deleted. .

When changing the layout of the shelves of the transport rack 8, the operator not only moves or changes the partition member 6 and the frontage code as described above, but also updates the changed layout and the frontage identification information indicated by the frontage code of each frontage. Input instructions to register (update) (update instructions). For example, the operator inputs information indicating the updated layout (layout information) using the operation unit 26 of the client device 2, and inputs frontage identification information indicated by the updated frontage code of each frontage using the code reader 28.

The processor 21 of the client device 2 transmits to the WCS 11 layout information indicating the changed layout input by the operator's operation and the updated frontage identification information of each frontage. The processor 31 of the WCS 11 acquires the changed layout information input by the operator at the client device 2 and the updated frontage identification information of each frontage. The processor 31 of the WCS 11 updates the setting information regarding the transport shelf 8 stored in the database 14 according to the changed layout information acquired from the client device 2 and the updated frontage identification information of each frontage.

Further, the client device 2 may cause the operator to select one layout from a plurality of layouts prepared in advance as a layout update instruction. For example, the processor 21 of the client device 2 displays an image (illustration, etc.) showing selectable layout candidates on the display unit 27, and selects a changed layout from the layout candidates displayed on the display unit 27 using the operation unit 26. selected.

As a specific example, the client device 2 may allow the operator to select a layout to be changed from the three layouts L1, L2, and L3 shown in FIG. In this case, the processor 21 displays images (illustrations, etc.) showing the three layouts L1, L2, and L3 on the display section 27, and selects one from the three layouts L1, L2, and L3 displayed on the display section 27 using the operation section 26. One layout may be selected. This allows the operator to simply select a desired layout from a plurality of layouts displayed as images, and thus can easily instruct the operator to change the layout.

Furthermore, if the partition members 6 can be moved to arbitrary positions, the client device 2 may have the operator instruct the position of each partition member 6 after the change, as an instruction to update the layout.
FIG. 6 is a diagram showing an example of a shelf in which partition members 6b and 6c can be moved to arbitrary positions on the transport shelf 8.
When the partition members 6b and 6c are movable to arbitrary positions as shown in FIG. 6, the processor 21 displays, for example, an image (illustration, etc.) of shelves as shown in FIG. 6 on the display unit 27, The positions of the partition members 6b and 6c in the image of the shelves displayed on the display section 27 may be instructed by the operation section 26. Thereby, the operator can instruct a change to a layout with a high degree of freedom, which is formed by moving the partition member 6 to an arbitrary position.

Note that the transport shelf 8 is provided with a partition position detection unit that detects the position of the movable partition member 6, and the client device 2 is configured to acquire information indicating the position of the partition member 6 detected by the partition position detection unit. You can also do it. In this case, the processor 21 of the client device 2 displays an image showing the position of the partition member detected by the detection unit on the display unit 27, and prompts the operator, using the operation unit 26, to change the layout displayed on the display unit 27. You may be asked to confirm (instruct). Thereby, the operator can easily instruct a change to a layout with a high degree of freedom, which is formed by moving the partition member 6 to an arbitrary position.
Further, the above-mentioned partition position detection section may be realized with a configuration that detects the position of the partition member 6 using an optical sensor (optical sensor) such as an infrared sensor. For example, as a partition position detection unit using an optical sensor, a plurality of optical sensors that detect the partition member 6 are installed side by side on a shelf board in the back, and the partition member 6 is detected based on the position of the optical sensor that detects the partition member 6. It may be configured to detect the position of. Further, as a configuration of the partition position detection section using an optical sensor, a material that reflects light (for example, infrared rays) from a light emitting section provided on the side of the shelf is provided on the partition member 6, and the reflection from the partition member 6 is A configuration may be adopted in which the position of the partition member 6 is detected by reading light.
Further, the partition position detection section described above may detect the position of the partition member 6 using a sensor (strain sensor) that detects the strain caused by the partition member 6. For example, as a partition position detection unit using a strain sensor, the strain sensor may be installed on the bottom of the shelf, and the position of the partition member 6 may be specified by detecting the weight of the partition member 6 with the strain sensor. .

Furthermore, in the transport system 1, the WCS 11 accepts changes in the layout of the transport shelves 8. When the WCS 11 receives an instruction to change the shelf layout, it requests the client device 2 for frontage identification information of each frontage 5 in the changed layout. When changing the layout of the transport shelf 8, the processor 21 of the client device 2 uses the code reader 28 to read the frontage code installed corresponding to each frontage in the changed layout.

For example, the processor 21 of the client device 2 displays on the display unit 27 a guide screen that guides reading of the frontage code installed for each frontage after the layout change. The operator causes the code reader 28 to read the frontage code installed at each frontage in accordance with the guidance displayed on the display unit 27. The processor 21 supplies the frontage identification information indicated by the frontage code read by the code reader 28 to the WCS 11.

Thereby, when the WCS 11 receives an instruction to change the shelf layout, it acquires the frontage identification information of each frontage 5 in the changed layout. When the WCS 11 acquires the layout after the change and the frontage identification information of each frontage in the layout after the change, the WCS 11 stores the setting information of the transport shelf 8 indicating the layout after the change and the frontage identification information of each frontage after the change into the database 14. Register (update).

Next, another display example of the frontage code on the shelf of the transport shelf 8 will be explained.
Although FIG. 5 or FIG. 6 shows an example in which the frontage code indicating the frontage identification information is displayed on the shelf board portion of the transport shelf 8, the frontage code indicating the frontage identification information may also be displayed on the partition member 6. good.

FIG. 7 is a diagram showing an example of displaying the frontage code of each frontage on the partition member 6 in the shelves of the transport shelf 8.
In the example shown in FIG. 7, the code c1 is attached to the partition member 6a and indicates the frontage identification information of the frontage formed by the partition member 6a. The code c2 is attached to the partition member 6b and indicates the frontage identification information of the frontage formed by the partition member 6b. The code c3 is attached to the partition member 6c and indicates the frontage identification information of the frontage formed by the partition member 6c. Here, it is assumed that the partition members 6b and 6c are movable in the lateral direction (in the direction of the partition member 6a or 6d along the article placement surface).

Here, it is assumed that the layout shown in FIG. 7 is the first layout L1 shown in FIG. 5. By overlapping the partition member 6c shown in FIG. 7 with the partition member 6d and moving the partition member 6b to the center, a second layout L2 shown in FIG. 5 can be set. In this case, the code c3 provided on the partition member 6c becomes unreadable, and the code c2 provided on the partition member 6b and the code c1 provided on the partition member 6a become readable. If the code c1 provided on the partition member 6a is used as the frontage code for the frontage 521, and the code c2 is used as the frontage code for the frontage 522, changes can be made without having to move (replace, etc.) the medium on which the frontage code is displayed. You can set the frontage code for each frontage in the later layout.

Note that the second layout L2 shown in FIG. 5 may be set by overlapping the partition member 6b with the partition member 6a and moving the partition member 6c to the center. In this case, if the code c2 provided on the partition member 6b is used as the frontage code for the frontage 521, and the code c3 is used as the frontage code for the frontage 522, there is no need to move (replace, etc.) the medium on which the frontage code is displayed. You can also set the frontage code for each frontage in the changed layout.

Further, by overlapping the partition members 6b and 6c shown in FIG. 7 on the partition member 6d, a third layout L3 shown in FIG. 5 can be set. In this case, the codes c2 and c3 provided on the partition members 6b and 6c become unreadable, and the code c1 provided on the partition member 6a becomes readable. If the code c1 provided on the partition member 6a is used as the frontage code for the frontage 531, the frontage code for the frontage 531 in the changed layout can be set without having to move (replace, etc.) the medium on which the frontage code is displayed. Can be set.

Alternatively, the third layout L3 shown in FIG. 5 may be set by overlapping the partition members 6b and 6c shown in FIG. 7 on the partition member 6a. In this case, if the code c3 provided on the partition member 6c is used as the frontage code for the frontage 531, the code c3 provided on the partition member 6c can be used as the frontage code for the frontage 531 in the changed layout without having to move (replace, etc.) the medium on which the frontage code is displayed. You can set the frontage code.

Next, an example will be described in which the layout is changed to a layout in which the upper and lower shelves in the transport shelf 8 are combined into one shelf.
FIG. 8 is a diagram showing an example in which the layout has been changed to one in which upper and lower shelves in the transport shelf 8 are combined into one shelf.
In the example shown in FIG. 8, the upper layout L11 has a frontage 611 formed by the partition member 6a1 and the partition member 6b1, and a frontage 612 formed by the partition member 6b1 and the partition member 6d1. The lower layout L12 has an opening 621 formed by the partition member 6a2 and the partition member 6b2, and an opening 622 formed by the partition member 6b2 and the partition member 6d2.

In layout L21, the combined area of frontage 611 and frontage 621 is changed to frontage 631, and frontage 631 is formed by partition member 6A3 and partition member 6B3, and frontage 632 is formed by partition member 6B3 and partition member 6D3. and has. In the layout L21, the frontage 631 is the area where the frontage 611 and the frontage 621 are combined, and the frontage 632 is the area where the frontage 612 and the frontage 622 are combined. In other words, in the layout L21, the frontage 631 and the frontage 632 have the height of two upper and lower levels.

The transport shelf 8 has a structure in which some of the shelves are removable, so that the layout of the upper and lower shelves can be changed. In the example shown in FIG. 8, by removing the upper shelf board on which the layout L11 is formed, it is possible to change the layout L21 to a layout L21 in which the two upper and lower stages are made into one stage. In addition, when changing the layout L21 to two upper and lower shelves, the partition members 6a1, 6b1, 6d1, 6a2, 6b2, and 6d2 may be replaced with partition members 6A3, 6B3, and 6D3 that are higher in height. good. Further, in the layout L21, the partition members 6a2, 6b2, and 6d2, which are the lower partition members, may be used as partition members 6A3, 6B3, and 6D to form the frontages 631 and 632.

Furthermore, in the layout L21, the frontage 631 is located at a position corresponding to the frontage 621, so the frontage code of the frontage 631 is the same as the frontage code of the frontage 621. Moreover, since the frontage 632 is located at a position corresponding to the frontage 622, the frontage code of the frontage 632 is the same as the frontage code of the frontage 622.

Next, an example of the operation of the client device 2 when changing the layout on the transport shelf 8 will be described.
FIG. 9 is a flowchart for explaining an example of the operation of the client device 2 when changing the layout on the transport shelf 8.
The processor 21 of the client device 2 receives an instruction input to the operation unit 26 by an operator. When changing the layout of the transport shelf 8, the operator uses the operation unit 26 to specify the transport shelf (POD) 8 to be changed in layout (ST10).

When the transport shelf 8 to be changed in layout is designated, the processor 21 requests the WCS 11 to change the layout of the target transport shelf 8 (ST11). For example, the processor 21 transmits the identification information (shelf identification information) of the transport shelf specified by the operator to the WCS 11 through the communication unit 25 along with a request for changing the layout.

When the WCS 11 permits a change in the layout of the designated transport shelf 8, the processor 21 accepts the designation of the shelf (BIN) whose layout is to be changed (ST12). The operator uses the operation unit 26 to specify the shelf whose layout is to be changed. The processor 21 transmits information indicating the shelf designated by the operation unit 26 (shelf information) to the WCS 11. On the other hand, the processor 21 may acquire, from the WCS 11, the current layout information on the shelves specified based on the transport shelf setting information.

When a shelf is specified, the processor 21 receives a layout designation for the specified shelf (ST13). The processor 21 can receive layout change instructions in various forms. For example, the processor 21 may accept an instruction to change the layout by having the user select a layout to be changed from a plurality of predetermined layouts, or may accept an instruction to change the layout by specifying the position of a partition member. Also good. Further, when the processor 21 acquires the current layout information of the specified shelf from the WCS 11, the processor 21 accepts a layout change instruction while displaying on the display unit 27 an image showing the current layout based on the current layout information. You can also do it.

The operator inputs a layout change instruction using the operation unit 26 and moves the position of the partition member 6 of the transport shelf 8 in accordance with the layout to be changed. When the operator completes the work of moving the partition member 6 of the transport shelf 8, the operator inputs an instruction to complete the movement of the partition position using the operation unit 26. The processor 21 receives an instruction to complete movement of the partition position from the operation unit 26 (ST14). When the designation of the layout and the movement of the partition positions are completed, the processor 21 transmits layout information indicating the changed layout to the WCS 11 (ST15).

Note that the transport shelf 8 may include a partition moving mechanism that moves the position of the partition member 6 in response to instructions from the client device 2 or the WCS 11. In this case, the client device 2 or WCS 11 supplies a control signal to the partition moving mechanism of the transport shelf 8 to move the partition member 6 according to the layout specified by the operator using the operation unit 26, and the partition moving mechanism The partition member 6 is moved to a position according to the specified layout. Thereby, when the movement of the partition member 6 according to the layout is completed, the processor 21 may determine that the movement of the partition position is completed.

When the designation of the layout and the movement of the partition positions are completed, the processor 21 uses the code reader 28 to read the frontage code for each frontage in the changed layout (ST16). The processor 21 transmits to the WCS 11 the frontage identification information for each frontage obtained by the code reader 28 reading the frontage code for each frontage.

After transmitting the layout information after the change and the frontage identification information for each frontage after the change, the processor 21 completes the layout change when it receives a notification from the WCS 11 that the layout change is completed (the settings after the change are completed). It shall be assumed that

Next, an example of the operation of the WCS 11 when changing the layout of the transport shelf 8 in the transport system 1 according to the embodiment will be described.
FIG. 10 is a flowchart for explaining an example of the operation of the WCS 11 when changing the layout on the transport shelf 8.
The processor 31 of the WCS 11 secures a communication state with the client device 2 through the client device interface 36 while the transport system 1 is in operation. When the operator changes the layout of the transport shelf 8, the processor 31 of the WCS 11 obtains a layout change request from the client device 2, as well as shelf identification information (shelf identification information) indicating the transport shelf 8 targeted for layout change. (ST20).

When the processor 31 acquires the identification information of the transport shelf to be changed in layout, it confirms that the transport shelf 8 specified by the identification information of the transport shelf is in a state where the layout can be changed. When the processor 31 confirms that the specified transport shelf 8 is in a state where the layout can be changed, the processor 31 allows the client device 2 to change the layout, and accepts the layout change for the transport shelf 8 (ST21).

After allowing the layout change, the processor 31 acquires information (shelf information) indicating the shelf (BIN) whose layout is to be changed in the transport shelf 8 from the client device 2 (ST22). Here, the processor 31 may acquire current layout information for the specified shelf from the database 14 and supply the current layout information to the client device 2.

After the shelf whose layout is to be changed is specified, the processor 31 acquires layout information indicating the changed layout for the specified shelf from the client device 2 (ST23). After acquiring the layout information indicating the changed layout, the processor 31 acquires frontage identification information for each frontage in the changed layout from the client device 2 (ST24).

For example, the processor 31 requests the client device 2 for frontage identification information of each frontage in the changed layout based on the layout information acquired from the client device 2, and in response to the request, the code reader 28 of the client device 2 reads the frontage identification information. Identification information may also be acquired. As a specific example, when there are two frontages in the changed layout, the processor 31 may acquire the identification information of one frontage and then the identification information of the other frontage.

Upon acquiring the changed layout information and the frontage identification information for each changed frontage from the client device 2, the processor 31 specifies setting information indicating the changed layout information and the changed frontage identification information for each frontage. It is registered (updated) in the database 14 as setting information of the transport shelf that has been set (ST25). When the processor 31 completes the registration of the layout information after the change, the frontage identification information of each frontage after the change, and the setting information included, the processor 31 notifies the client device 2 that the layout change has been completed, and ends the series of processes. .

As described above, in the conveyance system according to the embodiment, when changing the layout of the conveyance shelf, the target conveyance shelf and shelf tier are specified in the client device, and the layout information after the change and each frontage after the change are specified. identification information is input. The client device sends the input changed layout information and changed identification information of each frontage to the WCS. The WCS receives an instruction to change the shelf layout, and registers the changed layout information and setting information including the identification information of each frontage in the database.

Thereby, according to the conveyance system according to the embodiment, the layout on the conveyance shelf can be changed even during operation, and the conveyance shelf can be appropriately set according to the actual operation. As a result, the utilization rate of each opening on the transport shelf can be increased, and the transport system as a whole can efficiently process articles.

Next, the sorting shelf (DAS) 3 in the transport system 1 according to the embodiment will be explained.
As shown in FIG. 1, on the sorting shelf 3, a tray 4 is set as an article placement area on which articles sorted on each shelf stage are placed. In this embodiment, the layout of the trays 4 serving as article placement areas of the sorting shelf 3 can be changed. The conveyance system 1 accepts changes in the layout of the trays 4 on the shelves of the sorting rack 3 even during operation.

Each shelf of the sorting shelf 3 is provided with a display D and a button B at a predetermined position. The display device D and the button B provided on each shelf of the sorting shelf 3 are set to be enabled or disabled depending on the change in the layout of the trays 4 on each shelf. Validity or invalidity of the display device D and button B on the sorting shelf 3 may be set according to an instruction from the WCS 11, or may be set by an operator's work.

The WCS 11 receives a change in the layout of the trays 4 on the sorting shelf 3, and updates the setting information of the sorting shelf 3 stored in the database 14 according to the specified changed layout. Further, the WCS 11 may instruct the setting of the display D and the button B on the sorting shelf 3 to be enabled or disabled in response to a change in the layout of the trays 4 on the sorting shelf 3.

FIG. 11 is a diagram showing an example of the layout of the trays 4 on the shelves of the sorting shelf 3.
FIG. 11 shows three layouts T1, T2, and T3 as examples of the layout of the trays 4 on the shelves of the sorting shelf 3. Here, it is assumed that the operator changes the layout of the tray 4, which is the article placement area on the shelves of the sorting shelf 3.
In the first layout T1, trays 411, 412, and 413 are arranged on one shelf. In the first layout T1, the indicators D1, D2, and D3 and the buttons B1, B2, and B3 located at positions corresponding to the trays 411, 412, and 413 are enabled.

In the second layout T2, two trays 421 and 422 are arranged on one shelf. In the second layout T2, the tray 421 is arranged in the combined area of the trays 411 and 412 in the first layout T1, and the tray 422 is arranged in the area of the tray 413 in the first layout T1. In addition, the second layout T2 disables the display D2 and button B2, and enables the display D1 and button B1 at the position corresponding to the tray 421 and the display D3 and button B3 at the position corresponding to the tray 422. do.

In the third layout T3, one tray 431 is arranged on one shelf. In the third layout T3, the tray 431 is arranged in the combined area of the trays 411, 412, and 413 in the first layout T1. Further, in the third layout T3, the displays D2 and D3 and the buttons B2 and B3 are disabled, and the display D1 and the button B1 at the position corresponding to the tray 431 are enabled.

When changing the layout of the shelves of the sorting shelf 3, the operator inputs an instruction to update the layout of the sorting shelf 3. For example, the operator uses the operation unit 26 of the client device 2 to specify a shelf of the sorting rack 3 to be updated, and specifies a layout to be applied to the specified shelf.

Here, the client device 2 may cause the operator to select one layout from a plurality of layouts prepared in advance as the layout update instruction. For example, the processor 21 of the client device 2 displays an image (illustration, etc.) showing selectable layout candidates on the display unit 27, and selects a changed layout from the layout candidates displayed on the display unit 27 using the operation unit 26. selected.

As a specific example, the client device 2 may allow the operator to select a layout to be changed from three layouts T1, T2, and T3 as shown in FIG. 11. In this case, the processor 21 displays images (illustrations, etc.) showing the three layouts T1, T2, and T3 on the display unit 27, and uses the operation unit 26 to apply images from the three layouts T1, T2, and T3 displayed on the display unit 27. Alternatively, one layout may be selected. This allows the operator to simply select a desired layout from a plurality of layouts displayed as images, and thus can easily instruct the operator to change the layout.

When the layout update instruction is input, the processor 21 of the client device 2 transmits layout information indicating the changed layout input by the operator's operation to the WCS 11. The processor 31 of the WCS 11 receives the changed layout information input by the operator on the client device 2, and enables or disables each display D and each button B on the sorting shelf 3 according to the received changed layout information. Set. When the processor 31 of the WCS 11 sets the display device D and button B according to the changed layout, it updates the setting information regarding the sorting shelf 3 stored in the database 14 according to the changed layout information.

Next, as another example of the configuration of the sorting shelf 3, a configuration example in which a tray is arranged in a drawer provided at the bottom of the sorting shelf 3 will be described.

FIGS. 12A and 12B are diagrams showing an example of a configuration in which a tray for placing articles is arranged in a drawer provided at the bottom of the sorting shelf 3.
In the configuration example shown in FIGS. 12(a) and 12(b), the sorting shelf 3 is configured with three stages. In the example shown in FIG. 12(a), a plurality of drawers 71, 72, 73, and 74 are installed side by side at the bottom of the sorting shelf 3.

Trays 4 (471, 472, 473, 474) are arranged in each drawer 71, 72, 73, 74, respectively. Each drawer 71, 72, 73, 74 has a vertical mechanism 81 that raises and lowers the tray 4 placed in the drawer. The up and down mechanism 81 moves the tray 4 up and down according to the movements of the drawers 71, 72, 73, and 74. The vertical mechanism 81 moves the tray 4 upward when the drawers 71, 72, 73, and 74 are pulled out from the sorting shelf 3, as shown in FIG. 12(b). Further, the vertical mechanism 81 moves the tray 4 downward when the drawers 71, 72, 73, and 74 are pushed into the shelf from the state shown in FIG. 12(b). The up-and-down mechanism 81 may be any mechanism that can move the tray up and down so that the products placed on the tray can be stored in the shelf or pulled out from the shelf.

In the sorting shelf 3 shown in FIG. 12, by pulling out the bottom drawers 71, 72, 73, and 74, the tray 4 for placing articles moves upward. Therefore, the amount of vertical movement (movement) required by the operator to place the sorted items on the lowest tray 4 is reduced. As a result, the operator does not have to bend down or squat even when placing an article on the lowest stage, and the physical load is reduced. Furthermore, since the operator's workload is reduced, it is possible to prevent a decrease in the operator's work efficiency.

Furthermore, in the sorting shelf 3 shown in FIG. 12, the bottom drawers 71, 72, 73, and 74 have a configuration in which they are connected to adjacent drawers. That is, even at the bottom of the sorting shelf 3 shown in FIG. 12, it is possible to change the layout of the tray 4 as an article placement area where articles are placed.

FIG. 13 is a diagram showing an example in which the drawers 71 and 72 shown in FIG. 12 are connected as an example of a configuration for connecting adjacent drawers in the sorting shelf 3. Further, FIG. 14 is a diagram showing an example in which a tray 471 in the drawer 71 and a tray 472 in the drawer 72 are connected when the drawer 71 and the drawer 72 are connected.

When changing the layout of the sorting shelf 3 to have an article placement area of the combined size of the trays 471 and 472 at the lowest level, the drawers 71 and 72 are connected. In the example shown in FIG. 13, the drawer 71 and the drawer 72 are connected by a connector 91. The connector 91 fixes the connected drawers 71 and 72 so that they operate simultaneously. That is, the drawer 71 and the drawer 72 connected by the connector 91 are pulled out or pushed in at the same time. Note that the connector 91 is not limited to the shape shown in FIG. 13, but may be any connector that connects (fixes) adjacent drawers so that they operate simultaneously.

When connecting the drawer 71 and the drawer 72, one of the display D71 and button B71 provided on the drawer 71 and the display D72 and button B72 provided on the drawer 72 is set to be valid, and the other is set to be disabled. Set. In the example shown in FIG. 13, the display D71 and button B71 are set to be valid, and the display D72 and button B72 are set to be invalid. In this case, information regarding the article placement area (information such as the number of articles) of the combined tray 471 of the drawer 71 and the tray 472 of the drawer 72 that are connected together is displayed on the display D71. The button B71 lights up or blinks when the barcode of the article in the article placement area is scanned a predetermined number of times, and when the lit or blinking button B is pressed, it is notified that the delivery has been completed. .

Further, when the drawer 71 and the drawer 72 are connected to change the layout, the tray 471 and the tray 472 may be connected to form a tray 4 having the combined size of the tray 471 and the tray 472, or and tray 472 may be replaced with another tray of the combined size.

FIG. 14 is a diagram showing an example in which the tray 471 and the tray 472 are connected by a connecting tool 92 (92a, 92b, 92c). Connectors 92 (92a, 92b, 92c) connect trays 471 and 472. Trays 471 and 472 connected by connectors 92 (92a, 92b, 92c) are set in a drawer consisting of connected drawers 71 and 72, so that trays 471 and 472 are combined. It functions as a tray 4 of the same size.

Next, the operation of the client device 2 when changing the layout of the partition shelf 3 will be described.
FIG. 15 is a flowchart for explaining an example of the operation of the client device 2 when changing the layout of the partition shelf 3.
The processor 21 of the client device 2 receives an instruction input from an operator to the operation unit 26 while the transport system 1 is in operation. When changing the layout of the partition shelves 3, the operator uses the operation unit 26 to specify the partition shelves (DAS) 3 whose layout is to be changed (ST30).

When the sorting shelf 3 targeted for layout change is designated, the processor 21 requests the WCS 11 to change the layout of the targeted sorting shelf 3 (ST31). For example, the processor 21 transmits identification information (shelf identification information) of the sorting shelf specified by the operator to the WCS 11 through the communication unit 25 along with a request for changing the layout.

When the WCS 11 permits a change in the layout of the specified sorting shelf 3, the processor 21 accepts the designation of the shelf whose layout is to be changed (ST32). The operator uses the operation unit 26 to specify the shelf whose layout is to be changed. When the shelf whose layout is to be changed is specified, the processor 21 transmits information indicating the specified shelf (shelf information) to the WCS 11. Here, the processor 21 may display information indicating the current layout of the designated shelf on the display unit 27.

When a shelf is specified, the processor 21 receives a layout designation for the specified shelf (ST33). The processor 21 can receive the layout change instruction in various forms. For example, the processor 21 may accept a layout change instruction by having the user select a layout to be changed from a plurality of predetermined layouts, or may select a tray to be combined or separated as an area for placing articles. It may also be possible to receive instructions for changing the layout.

Furthermore, when changing the layout of the bottom row where drawers 71, 72, 73, and 74 are provided as shown in FIG. Perform the work of connecting or uncoupling the drawers. For example, when connecting the drawers 71 and 72, the operator inputs a layout change instruction using the operation unit 26, and also performs the operation of connecting the drawers 71 and 72 using the connector 91. Further, the operator may perform a task of connecting the tray 471 of the drawer 71 and the tray 472 of the drawer 72.

When the operator completes the layout designation and layout change work, the processor 21 transmits layout information indicating the changed layout to the WCS 11 (ST34). When the processor 21 receives a notification from the WCS 11 that the layout change has been completed (the settings after the change have been completed) after transmitting the changed layout information, it is assumed that the layout change has been completed.

Next, the operation of the WCS 11 when changing the layout of the sorting shelves 3 in the transport system 1 according to the embodiment will be described.
FIG. 16 is a flowchart for explaining an example of the operation of the WCS 11 when changing the layout of the sorting shelf 3.
The processor 31 of the WCS 11 secures a communication state with the client device 2 through the client device interface 36 while the transport system 1 is in operation. When the operator changes the layout of the sorting shelf 3, the processor 31 of the WCS 11 obtains a layout change request from the client device 2, as well as sorting shelf identification information (shelf identification information) indicating the sorting shelf 3 targeted for layout change. (ST40).

When the processor 31 acquires the identification information of the sorting shelf that is the target of the layout change, it confirms that the sorting shelf 3 specified by the identification information of the sorting shelf is in a state where the layout can be changed. When the processor 31 confirms that the specified sorting shelf 3 is in a state where the layout can be changed, the processor 31 allows the client device 2 to change the layout, and receives information regarding the layout change for the sorting shelf 3 (ST41).

After allowing the layout change, the processor 31 acquires information (shelf information) indicating the shelf whose layout is to be changed in the sorting shelf 3 from the client device 2 (ST42). Here, the processor 31 may obtain layout information indicating the current layout of the designated shelf from the database 14 and supply the current layout information to the client device 2.

After the shelf whose layout is to be changed is specified, the processor 31 acquires layout information indicating the changed layout of the shelf of the designated sorting shelf 3 from the client device 2 (ST43).

For example, it is assumed that the WCS 11 controls (sets) whether the display D and button B on the sorting shelf 3 are enabled or disabled. In this case, the processor 31 of the WCS 11 determines whether each display D and each button B on the sorting shelf 3 is valid or invalid based on the acquired layout information after the change, and based on the determination result, the processor 31 determines whether each display D and each button B on the sorting shelf 3 is Enable or disable each display D and each button B.

Note that the display device D and button B on the sorting shelf 3 may be set to be valid or invalid by the client device 2. In this case, the WCS 11 transmits information indicating whether the indicator D and button B on the sorting shelf 3 are enabled or disabled to the client device 2, and the processor 21 of the client device 2 controls the sorting shelf 3 based on the information acquired from the WCS 11. Set display D and button B in . In addition, the processor 21 of the client device 2 determines whether the display device D and button B on the sorting shelf 3 are valid or invalid according to the changed layout, and sets the display device D and button B on the sorting shelf 3 according to the determination. You may also do this.

Further, upon acquiring the changed layout information from the client device 2, the processor 31 registers (updates) the setting information indicating the changed layout information in the database 14 as the setting information of the specified sorting shelf 3 (ST45). . When the registration of the sorting shelf setting information including the changed layout information is completed, the processor 31 notifies the client device 2 that the layout change has been completed, and ends the process.

As described above, in the conveyance system according to the embodiment, when changing the layout of the sorting shelves, layout information indicating the changed layout specified and input by the client device is sent to the WCS. The WCS receives an instruction to change the layout of the shelves of the designated sorting shelf, and registers sorting shelf setting information including layout information indicating the changed layout in the database.

Thereby, according to the conveyance system according to the embodiment, the layout of the sorting shelves can be changed even during operation, and the sorting shelves can be appropriately set according to the actual operation. As a result, the utilization rate of each tray on the sorting shelf can be increased, and the entire conveyance system can efficiently process articles.
