Description

  The present invention relates to a component replenishment system and a component replenishment method that can request a component replenishment without placing a burden on an operator when assembling a work target article.

  In order to improve the efficiency of assembly management in assembly work, it is important to procure parts without delay. As one of the efficient parts procurement methods, a so-called “kanban system” procurement method is known. In the assembly line, each procured part is taken out from the parts box and consumed. When the parts in the parts box are consumed, the kanban attached to the empty parts box is removed and placed in the kanban post. Kanbans placed in the Kanban post are collected at regular intervals and collected in one place. The parts ordering system reads the supplier and product number from the barcode attached to the collected kanban, issues an order form, and sends it to the parts supplier with the kanban (for example, see Patent Document 1).

In addition, a method using a Kanban with RFID is disclosed for parts procurement in an assembly factory where parts are shipped from a parts factory (see, for example, Non-Patent Document 1). The Kanban board with RFID input to the assembly line of the assembly factory is read and transmitted to the parts factory via the network. In a parts factory, a Kanban board with RFID is automatically issued. The Kanban with RFID, which is automatically issued, is attached to the parts box (actual product) and shipped to the assembly plant.

  In the method described in Patent Document 1, in order to procure parts without delay, the kanban placed in the kanban post needs to be collected every predetermined time, which is troublesome. is there.

  The method described in Non-Patent Document 1 does not read the information on the Kanban with RFID on the assembly line, and therefore may not promptly reflect the progress in the assembly line. Furthermore, even when the method of reading information on Kanbans with RFID is adopted on the assembly line, Kanbans with RFID will remain on the assembly line site even after they are read, and the person in charge of the arrangement will be able to In addition, there is a problem that it takes time since it is necessary to always collect the Kanban with RFID. In addition, there is a possibility that a further problem may occur in which it is unclear whether or not the Kanban board with RFID left on the assembly line site has already been read and requested for parts procurement. This places a burden on the operator such as determining whether or not a component replenishment request has been made when it is necessary to replenish components.

  The present invention is an invention for solving the above-described problems, and provides a component replenishment system and a component replenishment method capable of requesting component replenishment without burdening an operator when assembling a work target article. The purpose is to do.

In order to achieve the object, the parts replenishment system includes an input means for inputting replenishment request information for parts at the work place, an output means for outputting replenishment request information at the parts storage place, and input by the input means. A parts replenishment system that includes a management server for managing the replenishment request information at an arbitrary place and requests replenishment of parts based on input information corresponding to a predetermined operation of an operator.

The input means includes a first slot having a first slot to which a first sheet attached with a first IC tag in which information for identifying a component is written and a first outlet to discharge the first sheet. A box (for example, box 51) and a first IC tag attached to the first box are read, the read information is transmitted to the management server, and after the transmission, the deletion of the first IC tag is written. An IC tag reading / writing unit (for example, an IC tag reader / writer unit 521), and a first sheet rewriting unit (for example, a sheet rewriting unit 522) that rewrites the first sheet so as to match the information in the first IC tag. ), And the output means supplies a second sheet to which the second IC tag is attached (for example, an actual product slip supply unit 66) and a second supply supplied from the sheet supply unit. No. discharging sheet A second box (e.g., box 61) having a discharge port, and an IC tag writing unit (e.g., writing predetermined information transmitted from the management server to the second IC tag attached to the second box) And an IC tag reader / writer unit 621) and a second sheet rewriting unit (for example, a sheet rewriting unit 622) for rewriting the second sheet so as to match the information in the second IC tag. To do. According to such a configuration, the operator only has to put the first sheet attached with the IC tag into the box when requesting the replenishment of the parts, and the inserted first sheet is the first sheet . 1 is discharged as a first sheet to which the initialized first IC tag is attached.

<< First Embodiment >>
FIG. 1 is a configuration diagram showing a component replenishment system according to an embodiment of the present invention. The parts replenishment system includes a results management server 10 that manages the results of parts replenishment, a parts ordering server 20 that requests and orders parts replenishment to a parts warehouse, a material terminal 30, and a parts replenishment request terminal installed at a work site. 50 and a parts replenishment receiving terminal 60 installed in the parts warehouse. The results management server 10, the parts ordering server 20, the material terminal 30, the parts replenishment request terminal 50, and the parts replenishment receiving terminal 60 are connected by a network 40 such as a LAN (Local Area Network).

  First, an outline of the system will be described. When an operator needs to replenish parts at an assembly shop, the worker inserts a product tag 70 into the parts replenishment request terminal 50. Then, the component replenishment request terminal 50 transmits component replenishment information described later on the actual product slip 70 to the result management server 10. The result management server 10 that has received the parts replenishment information makes an inquiry to an inventory management system (not shown), and if there is a stock, the parts replenishment receiving terminal 60 in the parts warehouse processes parts replenishment. The parts replenishment receiving terminal 60 outputs the actual product form 70. The person in charge of distribution at the parts warehouse attaches the output actual product form 70 to the parts for which the corresponding parts have been replenished, and distributes them to the corresponding assembly shop. As a result of inquiring to an inventory management system (not shown), the results management server 10 performs an ordering request process to the parts ordering server 20 when there is no inventory. The component ordering server 20 performs an ordering process with respect to a supplier (for example, a component manufacturer or a trading company). Here, as an example of component replenishment contents, component replenishment of components for attaching components to an electronic circuit board is taken as an example.

  The actual product form 70 includes a sheet 71 and an IC tag 72. The sheet 71 is a sheet in which information in the IC tag 72 in which information necessary for component replenishment is stored is written in characters so that an operator can visually understand the contents. It is a sheet that can be erased. The IC tag 72 is a non-contact wireless IC tag such as RFID (Radio frequency identification).

  The parts replenishment request terminal 50 is a terminal into which a product tag 70 is inserted when parts replenishment becomes necessary. The parts replenishment request terminal 50 is attached to the side of the box 51 having the insertion port 53 and the discharge port 54, reads the IC tag 72, transmits the read information to the results management server 10, and the sheet. A component replenishment request terminal main body 52 that can rewrite the writing of 71 and a tray 55 that holds the discharged actual product form 70 are provided.

The component replenishment request terminal main body 52 includes an IC tag reader / writer unit 521, a sheet rewriting unit 522, a communication unit 523, and a control unit 524. Have.

  When the IC tag reader / writer unit 521 confirms communication with the IC tag 72 when the product tag 70 is inserted into the box 51, the IC tag reader / writer unit 521 reads the information of the IC tag 72 attached to the product tag 70 and starts communication with the control unit 524. Send information.

  Specifically, the control unit 524 is realized by a CPU that operates according to a program. Upon receiving the communication start information from the IC tag reader / writer unit 521, the control unit 524 sends the communication start information with the IC tag 72 and the component information for identifying the component to the results management server 10 via the communication unit 523. Send. The communication start information includes, for example, the ID of the box 51 and the parts replenishment request date and time. The part information includes, for example, a material order number, product name, product number, manufacturer, number of replenishers, and arrival date / time. When the transmission to the results management server 10 is completed, the control unit 524 instructs the IC tag reader / writer unit 521 to delete the IC tag information.

  Further, the control unit 524 instructs the sheet rewriting unit 522 to erase, and erases the writing on the sheet 71. Since the sheet 71 uses a sheet such as thermal transfer, it can be erased by issuing an erase command.

  When the erasing of the sheet 71 is completed, the control unit 524 issues a discharge instruction for the actual product form 70, the discharge port 54 in the box 51 is opened, and the actual product form 70 is discharged from the box 51 and held on the tray 55. . Note that the writing on the sheet 71 of the actual product form 70 has been erased, and the information in the IC tag 72 has also been erased, so that it can be reused. Returning to the description of FIG.
