The actual product slip issuing process is a process for issuing the actual product slip by the actual product slip issuing device 300. FIG. 5 is a diagram showing an example of the data structure of the work management table 500 at the end of step S3. FIG. 6 is a diagram showing an example of the data structure of the work management table 500 at the end of step S8.

  Hereinafter, with reference to FIG. 4 to FIG.

(Step S1)
First, the control part 110 of the server apparatus 100 determines a work target as shown in FIG. Specifically, the administrator of the work management system 10 operates the input unit 130 to input information on the work target (for example, a production number, a product name, etc.). The control unit 110 temporarily stores the input information related to the work object in the memory 112.

(Step S2)
Next, the control part 110 determines the work content implemented with respect to the work target determined by step S1. Specifically, the administrator of the work management system 10 inputs the work content by operating the input unit 130. Here, the work content includes the name of the work process (hereinafter referred to as “process name”). In addition, when the work scheduled to be performed by the worker includes a plurality of work processes, a process name is input for each work process. Furthermore, as the work content, work content information is displayed in which the work content is displayed in an easy-to-understand manner so that the worker does not mistake the work content. For example, the work content information is HTML data. Further, the process name and the work content information do not need to be input in step S2. The process name and work content information may be stored in the server device 100 in advance, and in step S2, only the process name and work content information necessary for the work to be performed by the worker may be selected. In either case, the control unit 110 temporarily stores the input (or selected) process name and work content information in the memory 112.

(Step S3)
Subsequently, the control unit 110 generates a work management table 500. Specifically, the control unit 110 associates the manufacturing number 510 input in step S1, the process name 520 and the work content information 530 input (or selected) in step S2, respectively, with reference to FIG. A work management table 500 as shown is generated. At this time, the work management table 500 is stored in the memory 112 or the storage 113.

(Step S4)
In parallel with this, the administrator of the work management system 10 inserts (sets) the actual product slip into the actual product slip issuing device 300.

  The actual product slips may be inserted (set) into the actual product slip issuing apparatus 300 one by one, or a plurality of sheets may be set in advance in the paper feed tray (hopper) of the actual product slip issuing apparatus 300.

(Step S5)
After the actual product slip is inserted into the actual product slip issuing device 300, the control unit 110 instructs the actual product slip issuing device 300 to issue the actual product slip. Specifically, the server device 100 transmits the serial number input in step S <b> 1 to the actual product slip issuing device 300 together with a signal for instructing the issuance of the actual product slip via the external interface 150. At this time, the actual product slip issuing device 300 receives a signal for instructing the issuance of the actual product slip and the manufacturing number.

(Step S6)
The actual product slip issuing device 300 assigns (prints, etc.) the serial number received in step S5 to the leuco-type rewrite sheet 51 of the inserted actual product slip. Information other than the production number, for example, the product name, model number, quantity, etc. may be given together.

(Step S7)
Subsequently, the actual product slip issuing apparatus 300 acquires the actual product slip identification information (hereinafter referred to as “actual product ID”) assigned to each actual product slip from the NFC module 52 of the actual product slip, and sends it to the server device 100. Send. At this time, the server apparatus 100 receives the actual product ID via the external interface 150.

(Step S8)
The control unit 110 of the server apparatus 100 stores the actual product slip ID received in step S <b> 7 in the work management table 500. Specifically, the control unit 110 reads the work management table 500 stored in the memory 112 or the storage 113, and as shown in FIG. 6, manufactures the work object whose received product item ID 540 is determined in step S1. It is stored in association with the number 510 or the like.

(Step S9)
In addition, after the process of step S7 is completed, the actual product slip issuing apparatus 300 outputs (ejects) the actual product slip to which the manufacturing number of the work target to be worked by the worker is assigned.

  Through the above-described physical item issuance processing, it is possible to issue a physical item that is conveyed together with the work target. Further, by generating the work management table 500, the server apparatus 100 can manage the work (work process) and work content information scheduled to be performed by the worker.

  In the above example, information on the work object is input one by one and the actual product slip is output. However, all actual product slips manufactured on that day, or all manufactured products on a certain time zone on that day. A product slip may be output.

(2) Work Management Process FIG. 7 is a timing chart of the work management process executed in each work process. The work management process is a process for managing the work by the server device 100 when the worker is actually performing the work. FIG. 8 shows an example of the data structure of the work management table at the end of step S15. FIG. 9 is a diagram showing an example of the data structure of the work management table at the end of step S20. FIG. 10 is a diagram showing an example of the data structure of the work management table at the end of all work processes.

  Hereinafter, the work management process will be described with reference to FIGS. The work management process is executed for each work process. In the present embodiment, each work process is performed by different workers, and each worker carries a different display device 400. In addition, both the work object and the actual product slip issued by the above-described actual product slip issuing process are transported from the work site of each work process to the work site, and each work process is performed in order. As described above, the work start NFC tag 20a and the work end NFC tag 20b are installed in the work place of each work process (FIG. 1).

(Step S11)
When an operator starts each work process, when the operator holds the display device 400 over the work start NFC tag (process providing device) 20a, the short-range wireless communication unit 450 of the display device 400 moves to the work start NFC tag 20a. The stored process specifying information is acquired according to the near field communication standard. The process specifying information acquired in step S11 is information for specifying the work process started by the worker, and may be information corresponding to the process name 520 of the work management table 500, for example.

(Step S12)
Then, the communication unit 440 of the display device 400 exchanges a predetermined signal with the communication device 200 by wireless communication, and establishes a connection between the server device 100 and the display device 400. Thereafter, the control unit 410 transmits the process specifying information acquired in step S11 to the server device 100 via the communication unit 440. At this time, the server device 100 receives the process specifying information transmitted from the display device 400.

(Step S13)
Subsequently, when the worker holds the display device 400 over the NFC module 52 portion of the actual product form assigned to the work object, the near field communication unit 450 of the display device 400 causes the actual product stored in the NFC module 52 to be displayed. The vote ID is acquired according to the near field communication standard.

(Step S14)
The control unit 410 transmits the actual product slip ID acquired in step S13 to the server device 100 via the communication unit 440, and requests work content information regarding the work (work process) that the worker is about to start. At this time, the control unit 410 also transmits display device identification information (hereinafter referred to as “display device ID”) for identifying the display device 400 to the server device 100. Then, the server device 100 receives the actual product slip ID and the display device ID transmitted from the display device 400. The display device ID may be an IP address assigned to the display device 400.

(Step S15)
The control unit 110 of the server device 100 stores the display device ID received in step S14 in the work management table 500. Specifically, the control unit 110 reads the work management table 500 stored in the memory 112 or the storage 113. Then, as shown in FIG. 8, the control unit 110 stores the received display device ID 550 in association with the process specification information (process name 520) received in step S12 and the actual product ID ID 540 received in step S14. . Furthermore, the control unit 110 stores information indicating that the work (work process) is started (for example, information indicating “completed”) as the start 560 and stores the information.

(Step S16)
Subsequently, the control unit 110 provides necessary work content information to the display device 400 specified by the display device ID received in step S14. Specifically, the control unit 110 extracts, from the work management table 500, work content information 530 associated with the process identification information (process name 520) received in step S12 and the actual product slip ID 540 received in step S14. . Thereafter, the control unit 110 transmits the extracted work content information 530 via the communication interface 140. At this time, the display device 400 receives the work content information 530 transmitted from the server device 100 by wireless communication.

(Step S17)
The control unit 110 of the display device 400 displays the work content information (for example, HTML data) received in step S16 on the display unit 420. Thus, the worker can perform the work while referring to the work content information displayed on the display unit 420.

(Step S18)
After the work on the work object (work process) is completed, when the worker holds the display device 400 over the work end NFC tag (process providing apparatus) 20b, the short-range wireless communication unit 450 moves to the work end NFC tag 20b. The stored process specifying information is acquired according to the near field communication standard. Note that the process identification information acquired in step S18 is information for identifying the work process completed by the worker, and may be information corresponding to the process name 520 of the work management table 500, for example.

(Step S19)
Then, the control unit 410 of the display device 400 transmits the process specifying information acquired in step S18 to the server device 100 via the communication unit 440. At this time, the server device 100 receives the process specifying information transmitted from the display device 400.

(Step S20)
The control unit 110 of the server apparatus 100 stores information indicating that the work (work process) is completed (for example, information indicating “done”) in the work management table 500 as an end 570. Specifically, the control unit 110 reads the work management table 500 stored in the memory 112 or the storage 113, and stores an end 570 in association with the start 560 stored in step S15, as shown in FIG. .

  Thereafter, the work management process described above is executed for each work process, and various information obtained in each work process is added to the work management table 500 as shown in FIG.

  Through the above work management processing, the work management table 500 is created in the server device 100. With reference to the work management table 500, the administrator of the work management system 10 can easily grasp the progress of work to be performed on the work object of interest.

  In addition, the work content information of each work process is managed (stored) by the server device 100, and the server device 100 performs appropriate work content in response to a request from the display device 400 used in the work place of each work process. Information is provided to the display device 400. Therefore, even when the work content is changed or when the work content of a product with a new production number is registered, the work management table 500 need only be rewritten. Therefore, the application of the display device 400 does not need to be updated and can be easily maintained.

  In addition, since the display device 400 in which the short-range wireless communication unit 450 is mounted does not require a special application except for a standard installed application, the introduction cost of the system can be suppressed. . As long as there is a display device 400 equipped with the short-range wireless communication unit 450 and a communication infrastructure, it can be operated immediately anywhere in the world.

  Each processing unit of each timing chart described above is divided according to main processing contents in order to facilitate understanding of the work management system 10. The invention of the present application is not limited by the method of classification of the processing steps and the names thereof. The processing performed in the work management system 10 can be divided into more processing steps. One processing step may execute more processes.

<Modification>
Moreover, said embodiment intends to illustrate the summary of this invention, and does not limit this invention. Many alternatives, modifications, and variations will be apparent to those skilled in the art.

  For example, in the above embodiment, each work process has been described as being performed by different workers, but may be performed by the same worker. Further, the same display device 400 may be used (shared) throughout the entire work process (from the first process to the final process). In this case, even if the display device 400 does not transmit the actual item ID to the server device 100 each time in each work process, the display device ID 550 of the work management table 500 has the same IP address in all work processes. With reference to the display device ID 550, the work object can be specified. Therefore, the display device 400 omits the transmission of the actual item ID to the server device 100 when requesting work content information from the server device 100 in a step other than the first step (first step). It's okay. Of course, even if the same display device 400 is used for all work processes, if a different display apparatus ID (IP address) is assigned to each work process, the actual product ID is transmitted. Do not omit.

  In the above embodiment, the work start NFC tag 20a and the work end NFC tag 20b are installed in the work place of each work process. However, the present invention is not limited to this, and only one NFC tag may be installed. In this case, even at the end of the work (work process), the display device 400 does not have to notify the server apparatus 100 that the work has been finished (transmit the process specifying information). Further, the same NFC tag may be used at the start and end of work (work process), and the start and end of work may be notified to the server apparatus 100 as in the above embodiment.

  Moreover, in said embodiment, the display apparatus 400 is demonstrated as a small terminal which a worker can carry. However, the present invention is not limited to this, and the display device 400 is a device having a large display screen (including a liquid crystal television, a plasma television, a large tablet terminal, etc., hereinafter referred to as a “large display device”). There may be.

FIG. 11 is a schematic configuration diagram when the display device 400 is a large display device.
In the example shown in FIG. 11, one large display device is arranged in each work process workplace. In this case, unlike the above-described embodiment, it is not necessary to arrange the work start NFC tag 20a and the work end NFC tag 20b. Instead, the large display device stores the process specification information stored in the work start NFC tag 20a and the work end NFC tag 20b, and specifies the process together with the product tag ID when the product tag 50 is held over. Information needs to be transmitted to the server apparatus 100.

  With such a modification, work guidance can be displayed on a larger screen than a portable small terminal. Moreover, the troublesomeness for the operator to carry the display device 400 is also eliminated.

  Further, the actual product slip issuing device 300 of the above-described embodiment has a function of erasing information (printed) on the surface of the actual product slip. Can also be used.
