Description

  The present invention relates to a picking assistance device, a picking assistance method, a picking system, and a program.

  In the chemical distribution warehouse, every time an order is placed, an operation is performed in which the ordered chemicals are taken out from the chemical shelves and accumulated in one container. This operation is called picking (see, for example, Patent Document 1). When picking is completed, the container is shipped.

  In general, since there are many kinds of medicines, the number of medicine shelves in one distribution warehouse is very large. For this reason, if the picking is performed with the container placed at one place, the movement distance of the worker becomes long, and it takes a long time to complete the picking.

  Therefore, some distribution warehouses are provided with a plurality of stations, a chemical shelf is installed at each station, and a container is allowed to flow between the stations using a belt conveyor. In such a distribution warehouse, when there is an order, the order information is first sent to each station. Each station is provided with a basket, and an operator accumulates medicines in the basket based on the order information without waiting for the container to arrive. When the container arrives, the medicine is taken out from the basket and transferred to the container. By doing so, the time required to complete the picking is shortened.

  This mechanism will be described in more detail. Each station is provided with a temporary table for temporarily storing the basket. The temporary table is divided into a plurality of spaces, and one basket can be placed in each space. Each space is provided with a plurality of colors of lamps.

Each station receives order information one by one. When the order information is received, the lamp of the space where the basket corresponding to the order information is to be lit in green. The worker who confirms this green lighting starts picking with a basket. When picking is completed, another worker inspects and places a basket containing chemicals in the space. When the container arrives, the lamp in the space where the cage corresponding to the container is placed blinks in a light bulb color. When the worker confirms this blinking, the worker starts transshipment to the container.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a system configuration diagram of a picking system 1 used for performing a picking operation in a distribution warehouse having a plurality of stations. As shown in the figure, the picking system 1 includes a plurality of stations 2 (in the figure, five from station 2-1 to station 2-5), a main line 3 of a belt conveyor, and a server device 10. , Including the container C. In each station 2, a belt conveyor pull-in line 4, a station terminal device 20, a plurality of baskets K, a temporary table, and a plurality of medicine shelves are installed. Here, it is assumed that each station is provided for each type of medicine.

  When the server device 10 accepts the medicine order, the server device 10 determines one or a plurality of stations 2 that need to perform the picking work. Then, order information indicating the order is transmitted to the station terminal device 20 of the station 2 (hereinafter referred to as the picking work execution station 2) that has determined that the picking work needs to be performed. Further, the container C is placed on the main line 3 from one end X1 of the main line 3.

  The container C moves on the main line 3 and finally reaches the other end X2 of the main line and is used for shipping processing. When the container C reaches the picking work execution station 2 while the main line 3 is moving, the server device 10 moves the container C toward the drawing line 4 of the station 2 using a branching unit (not shown).

  At the picking work execution station 2, the worker confirms the order information received by the station terminal device 20, and performs the preceding picking using the basket K. At this time, the worker attaches a wireless tag device (not shown in FIG. 1) to the basket K. When the preceding picking is completed, another worker performs inspection, and the basket K that has been subjected to the preceding picking and inspection is temporarily stored in the temporary table.

  Since the above operations are sequentially performed for a plurality of orders, a large number of baskets K waiting to reach the container C are arranged in the station 2. In the present embodiment, when the container C arrives, the LED indicator provided in the RFID tag device corresponding to the container C is turned on. As a result, the worker identifies the basket K corresponding to the container C that has arrived, and reloads the chemicals contained in the basket K into the container C. Hereinafter, a specific configuration for realizing this will be described with reference to functional blocks of each device.

  FIG. 2 is a schematic block diagram showing functional blocks of the server device 10, the station terminal device 20, and the wireless tag device 30.

  As shown in FIG. 2, the server device 10 includes an order input receiving unit 11, an order table storage unit 12, a container sending processing unit 13, an order information transmitting unit 14, a tag ID input receiving unit 15, an arrival detecting unit 16, and a tag ID. A reading unit 17, an instruction information transmission unit 18, and a transshipment completion detection unit 19 are included. A plurality of bar code readers 41 are connected to the server device 10, and each bar code reader 41 is installed on the side of the main line 3 end X 1 side of the pull-in line 4 of each station 2 (side the pull-in line 4 entrance). Has been. In the present embodiment, the server device 10 functions as a picking auxiliary device for assisting picking work performed in a distribution warehouse having a plurality of stations.

  As shown in FIG. 2, the station terminal device 20 includes an order information receiving unit 21, an order information notifying unit 22, a barcode information processing unit 23, and a transshipment completion input receiving unit 24. A bar code reader 40 is connected to the station terminal device 20.

  Further, the wireless tag device 30 includes a receiving unit 31 and a notification unit 32 as shown in FIG. A plurality of the wireless tag devices 30 are placed at each station.

  A bar code 50 that is different for each wireless tag device 30 is attached to each wireless tag device 30. The server device 10 stores a tag ID table (not shown) that associates the barcode 50 with a tag ID that is different for each wireless tag device 30. Similarly, a different barcode 51 is affixed to each container C. The server apparatus 10 stores a container ID table (not shown) that associates the barcode 51 with a container ID that is different for each container C.

  The server device 10 and the station terminal device 20 are interconnected by a network such as a LAN (Local Area Network). The server device 10 transmits a wireless signal to the wireless tag device 30, and the wireless tag device 30 receives this wireless signal. For this radio signal transmission / reception, for example, an active RFID (Radio Frequency Identification) system is preferably used.

  Hereinafter, the function of each functional block will be specifically described.

  First, the order input receiving unit 11 receives an input of a medicine order by an operator. And order ID which is the identification information of a different order for every order is provided. The order input receiving unit 11 acquires order information including the assigned order ID and the order contents, and stores them in the order table stored in the order table storage unit 12.

  FIG. 3 is a diagram showing the contents stored in the order table. As shown in the figure, the order table stores the order information and stores the container ID, the station ID (identification information of the station 2 that is different for each station 2), and the combination of the tag ID in association with the order information. To do.

  When new order information is stored in the order table, the order information transmission unit 14 selects one or a plurality of picking work execution stations 2 based on the order contents included in the order information. Then, order information is transmitted to each selected picking work execution station 2.

  The order information receiving unit 21 receives the order information transmitted by the server device 10. When the order information receiving unit 21 receives the order information, the order information notifying unit 22 notifies the worker of a picking instruction related to the order information. Specifically, information indicating the picking instruction is displayed on a display (not shown).

  When the operator confirms the notification performed by the order information notification unit 22, the worker selects one wireless tag device 30. The wireless tag device 30 is configured to be easily attached to and detached from the picking basket K. Specifically, a configuration that can be hooked on the edge of the cage K, or a configuration that uses Velcro (registered trademark), a seal, or the like can be used.

  Next, the operator holds the surface of the selected wireless tag device 30 on which the barcode 50 is attached over the barcode reader 40 and causes the barcode reader 40 to read the barcode 50. When this process is completed, the worker attaches the selected RFID tag device 30 to the basket K, and then appropriately starts the preceding picking. When the preceding picking started in this way is completed, the basket K containing the medicine is inspected by another worker and temporarily stored in the temporary table.

  The barcode information processing unit 23 combines the barcode 50 read by the barcode reader 40 and the order information received by the order information receiving unit 21, and transmits the combined information to the server device 10.

  The tag ID input receiving unit 15 receives the combination of the order information and the barcode 50 from the barcode information processing unit 23 of each picking work execution station 2. The received barcode 50 is replaced with a tag ID using the tag ID table. Accordingly, the tag ID input receiving unit 15 receives an input of a tag ID indicating the wireless tag device 30 corresponding to each order for each picking work execution station 2. Then, the tag ID input receiving unit 15 associates the station ID indicating the picking work execution station 2 that transmitted the combination and the tag ID included in the combination with the order information included in the combination, Remember me.

  When new order information is stored in the order table, the container sending processing unit 13 performs processing for sending the container C to the main line 3 in accordance with the order indicated by the order information. This process may be a process including a mechanical process for sending the container C to the main line 3, or a process for prompting the worker to send the container C (for example, using a display or the like). Notification processing). The container sending processing unit 13 acquires a container ID indicating the container C when sending the container C, and stores it in the order table in association with the order information.

  When the barcode 51 enters the predetermined range from the barcode reader 41, the barcode reader 41 reads the barcode 51 and transmits it to the server device 10. The arrival detection unit 16 receives the bar code 51 thus transmitted. Then, the received barcode 51 is replaced with a container ID using the container ID table. The arrival detection unit 16 acquires the container ID in this way, and detects that the container C sent in accordance with the processing of the container sending processing unit 13 has reached one of the plurality of stations 2. Then, the acquired container ID and the station ID indicating the station 2 that transmitted the barcode 51 are combined and output to the tag ID reading unit 17.

  When the arrival detection unit 16 detects the arrival of the container C, the tag ID reading unit 17 stores the station ID indicating the station 2 that the container C has reached and the container ID of the container C in association with each other. The ID is read from the order table. Specifically, the tag ID stored in the order table for the combination of the container ID and the station ID input from the arrival detection unit 16 is read.

  The instruction information transmitting unit 18 transmits instruction information (notification execution instruction information) for instructing the wireless tag device 30 indicated by the tag ID read by the tag ID reading unit 17 to perform a predetermined notification process. To do.

  Specifically, the server device 10 includes a bit string transmission unit (not shown) that periodically transmits a bit string having bits corresponding to each of the plurality of wireless tag devices 30. FIG. 4 shows an example of this bit string. For example, when 1024 RFID tag devices 30 can be used, the bit string transmission means transmits a 1024-bit bit string every 0.5 seconds. In this case, each of the 1024 RFID tag devices 30 corresponds to any of the 0th to 1023th bits of the 1024 bits constituting the bit string without duplication.

  The instruction information transmitting unit 18 notifies the wireless tag device 30 indicated by the tag ID read by the tag ID reading unit 17 of the predetermined value of the bit value corresponding to the wireless tag device 30 in the bit string. The notification execution instruction information is transmitted by setting a predetermined value indicating that the process is instructed.

  Here, each bit constituting the bit string indicates an instruction to perform the notification process when the value thereof is “1”. That is, the predetermined value indicating that the notification processing is instructed is “1”.

  On the other hand, each bit constituting the bit string indicates an instruction not to perform the notification process when the value is “0”. The instruction information transmitting unit 18 sets the value of the bits constituting the bit string to a predetermined value “0” indicating that the predetermined notification processing is not performed, thereby allowing the wireless tag device 30 corresponding to the bit to be transmitted. In response to this, instruction information (notification non-execution instruction information) for instructing not to perform the predetermined notification process (to interrupt the execution of the predetermined notification process) is transmitted.

  The receiving unit 31 receives instruction information transmitted by the server device 10. Specifically, the receiving unit 31 receives the bit string, and reads the value of the bit corresponding to the wireless tag device 30 from the received bit string. When the value is a predetermined value “1” indicating that the notification processing is instructed, the notification execution instruction information is received. On the other hand, when the value is a predetermined value “0” indicating that the notification processing is not performed, the notification non-execution instruction information is received.

  The notification unit 32 performs the predetermined notification process according to the instruction information received by the reception unit 31. That is, when the receiving unit 31 is receiving notification execution instruction information, the notification unit 32 performs the predetermined notification process. When the receiving unit 31 receives the notification non-execution instruction information, the notification unit 32 does not perform the predetermined notification process.

  In a specific example, the notification unit 32 includes an LED display, and the predetermined notification process is a process of turning on the LED display. In this case, the notification execution instruction information indicates a turn-on instruction for the LED display, and the notification non-execution instruction information indicates a turn-off instruction for the LED display.

  In this way, the notification performed by the notification unit 32 allows the worker to identify the basket K corresponding to the container that has arrived. The worker who has identified the basket K takes out the medicine from the basket K and reloads it into the container C. When the transshipment operation is completed, the container C is poured into the main line 3 and information indicating that the transshipment is completed is input in the station terminal device 20.

  The transshipment completion input reception unit 24 receives input by the operator of information indicating that transshipment is completed. Then, transshipment completion information indicating that transshipment is completed is generated and transmitted to the server device 10.

  The transshipment completion detection unit 19 receives the transshipment completion information transmitted from the station terminal device 20, so that the instruction information transmission unit 18 transmits the notification execution instruction information to the container C from the basket K. Detect that the transshipment of is complete.

  When the transshipment completion detection unit 19 detects the completion of transshipment, the instruction information transmission unit 18 starts to transmit notification non-execution instruction information to the wireless tag device 30 that is transmitting the notification execution instruction information. In other words, the transmission of the notification execution instruction information to the wireless tag device 30 is stopped.

  In a specific example, the instruction information transmission unit 18 transmits notification execution instruction information to only one wireless tag device 30 at a time for each station 2. When the notification execution instruction information is transmitted to two or more wireless tag devices 30 at the same time, the worker does not know which basket K can be transferred to the container C that has arrived first. Because it will end up. Then, the instruction information transmission unit 18 holds the tag ID of the wireless tag device 30 currently transmitting for each station 2. When the instruction information transmitting unit 18 detects that the transshipment completion detecting unit 19 has completed transshipment for the station 2, the instruction information transmitting unit 18 does not notify the wireless tag device 30 indicated by the tag ID held for the station 2. Transmission of execution instruction information is started. Further, the instruction information transmission unit 18 deletes the tag ID of the wireless tag device 30 and the station ID stored in combination with the tag ID from the order table.

  The processing described above will be described in more detail again with reference to the processing sequence diagram of the picking system 1.

  FIG. 5 is a diagram illustrating a processing sequence of the picking system 1. As shown in the figure, the server device 10 first receives an input of an order (S1). Then, an order ID (here, “A”) is assigned and stored in the order table (S2). Next, order information indicating the accepted order is transmitted to the station terminal device 20 (S3).

  When the server apparatus 10 transmits the order information in the process of S3, the server apparatus 10 performs a process for sending the container C (S4), and associates the container ID of the sent container C with the order ID “A” in the order table. (S5).

  The station terminal device 20 receives the order information (S6), and notifies the operator of the order content indicated by the received order information (S7). The worker who has received this notification selects one RFID tag device 30 and causes the barcode reader 40 to read the barcode 50 attached to the selected RFID tag device 30 (S8). The station terminal device 20 receives an input of the barcode 50 from the barcode reader 40 and transmits it to the server device 10 (S9). When the process of S8 is completed, the worker appropriately starts the preceding picking work (S10). At this time, the worker attaches the selected wireless tag device 30 to the basket K used for the preceding picking. When picking is completed, inspection is performed (S11).

  The server device 10 receives the barcode 50 from the station terminal device 20, and includes a tag ID indicated by the barcode 50 and a station ID indicating the station 2 to which the station terminal device 20 that transmitted the barcode 50 belongs. The combination is stored in the order table in association with the order ID “A” (S12).

  Next, the server device 10 detects the arrival of the container C at any one of the stations 2 (here, “B”) (S13). Then, the tag ID combined with the station 2 “B” is read from the order table regarding the container ID of the container C that has detected arrival (S14). The server device 10 starts transmitting notification execution instruction information to the wireless tag device 30 indicated by the tag ID thus read (S15).

  The wireless tag device 30 receives the notification execution instruction information transmitted to the wireless tag device 30 and starts executing the notification process (S16). The worker who has confirmed this notification processing carries out the transshipment operation of the medicine in the basket K to the container C, and upon completion, inputs information indicating that the transshipment has been completed in the station terminal device 20 (S17). . Note that the inspection work in S11 may not be performed when the worker confirms the notification process. In this case, the worker performs the transshipment work after performing the inspection work in S11. .

  When the station terminal device 20 receives an input by the operator of information indicating that the transshipment is completed, the station terminal device 20 generates transshipment completion information indicating that the transshipment is completed, and outputs it to the server device 10 (S18). Upon receiving the transshipment completion information, the server device 10 detects that the transshipment from the basket K to the container C is completed with respect to the radio tag device 30 that is transmitting the notification execution instruction information. Then, transmission of notification non-execution instruction information is started (S19).

  As described above, according to the picking system 1, when the RFID tag device 30 is attached to the basket K, when the container C arrives, the RFID tag device 30 attached to the cage K corresponding to the container C notifies Since the process is performed, the operator can freely determine the place where the basket K is placed, and can identify the basket K corresponding to the container C that has reached.

  Further, the notification process by the wireless tag device 30 can be performed only when necessary (when the transshipment work to the container C is to be performed).

  Further, since the bit string is periodically transmitted, the wireless tag device 30 can receive the instruction information at the next opportunity even if it fails to receive the instruction information due to deterioration of the radio wave condition or the like.

  The present invention is not limited to the above embodiment. For example, in the above embodiment, only one RFID tag device 30 is selected by the worker, but a plurality of RFID tag devices 30 may be selectable. In this case, it is desirable to use a plurality of tag IDs combined with the station ID in the order table.

  In the above embodiment, the barcode is used to identify the wireless tag device 30 and the container C. However, RFID may be used instead of the barcode.

  In addition, the bit string transmission unit may transmit the bit string with a predetermined preamble. In this way, the wireless tag device 30 can determine the start portion of the bit string that is sequentially transmitted from the preamble.

  In addition, by recording a program for realizing the functions of the server device 10 and the station terminal device 20 on a computer-readable recording medium, causing the computer system to read and execute the program recorded on the recording medium, You may perform said each process.
