In addition, during this lap, replacement work of a semi-finished product that has been mounted up to that time to a new semi-finished product is also performed. In the following description, when items common to the work table W1, the work table W2,..., The work table W9 are described, these are simply referred to as “work table W”. Each of these work tables W corresponds to an example of a “table” according to the present invention.

  On the other hand, the position of the transmission unit TR (relative and three-dimensional position of the transmission unit TR with respect to the display device D) is controlled under the control of the transmission control unit CR. The corresponding work instruction data IT is transmitted. Therefore, the transmission control unit CR controls the position of the transmission unit TR under the control of the management server SV, and sends the work instruction data IT to be output to the display device D via the transmission unit TR from the management server SV. This is received, output to the transmission unit TR, and transmitted to the display device D. Note that the wireless communication between the display device D (more specifically, the receiving unit 10 described later) and the transmitting unit TR is, for example, a short-range wireless communication method (more specifically, for example, so-called NFC (Near Field Communication)). Wireless communication by a system or Transfer Jet (registered trademark) system) is preferable.

  In the above configuration, the management server SV indicates the attachment position of the display device D on the work table W provided with the identification data ID read by the reader / writer RW and the tag T in which the identification data ID is stored.

Accordingly, the management server SV detects the mounting position based on the read identification data ID and the mounting position data, and transmits the transmission unit TR so as to position the transmission unit TR at a position facing the mounting position. Control CR. Then, work corresponding to the content of the work instruction to be displayed on the display device D in the work table W provided with the tag T in which the identification data ID is stored is transmitted from the transmission unit TR located at the directly facing position. In order to transmit the instruction data IT, the work instruction data IT is output to the transmitter TR via the transmission controller CR. Thereby, the display device D in the work table W provided with the tag T in which the identification data ID is stored receives the work instruction data IT via the transmission unit TR and displays the work instruction data IT for presentation to the worker. .

  The series of operations described above are sequentially and individually executed for each work table W that circulates on the production line L and each display device D provided thereto, according to the movement of the work table W.

  Next, the structure and the like of the work table W according to the embodiment will be described more specifically with reference to FIG.

  As illustrated in FIG. 2, each work table W according to the embodiment is equipped with a refrigerator RG manufactured by assembly or the like in the manufacturing line L according to the embodiment, and the manufacturing line is rotated by rotation of the wheels WH provided below the bottom surface. Move around L. A tag T for storing the identification data ID for identifying the work table W from another work table W in a non-volatile manner is provided on the bottom surface (see FIG. 2) of the work table W, for example. At this time, since the tag T is provided at this position, the reader / writer RW that reads the identification data ID from the tag T is also provided at a height from the floor near the position of the tag T.

  On the other hand, the display device D is attached to each work table W. In the work table W according to the embodiment, the display device D can be attached to each work table W at a position convenient for reference during assembly or the like on the work table W. More specifically, the display device D can be attached to any one of the attachment positions P0 to P7 illustrated in FIG. For example, when assembling the lower part or bottom of the refrigerator RG, the display device D is attached to any one of the attachment position P0, the attachment position P1, and the attachment position P2 shown in FIG. For example, when assembling the refrigerator RG above or on the top surface, the display device D is attached to any one of the attachment position P5, the attachment position P6, and the attachment position P7 shown in FIG. The attachment position data indicating the attachment position for each work table W in the display device D is associated with the identification data ID for identifying the work table W and recorded in the management server SV. It is described in advance in the position table TB. In the following description, when the matters common to the attachment position P0 to the attachment position P7 are described, these are collectively referred to simply as “attachment position P”.

  Next, schematic configurations and operations of the management server SV and the display device D according to the embodiment will be described with reference to FIG.

  First, as illustrated in FIG. 3A, the management server SV according to the embodiment includes an interface 1, a CPU 2, a nonvolatile area such as a hard disk or a ROM (Read Only Memory), and a volatile memory such as a RAM (Random Access Memory). And a recording unit 3 for recording the mounting position table TB according to the embodiment in a non-volatile manner, an operation unit 4 including a keyboard and a mouse, and a display 5 including a liquid crystal display. . At this time, the interface 1 corresponds to an example of the “position information output unit” according to the present invention, the CPU 2 corresponds to an example of the “detection unit” according to the present invention, and the recording unit 3 corresponds to the “position information storage unit” according to the present invention. It corresponds to an example of “means”. In the following description, the CPU 2 of the management server SV is simply referred to as “CPU 2”.

  In the above configuration, the interface 1 controls the exchange of the identification data ID and the work instruction data IT between the reader / writer RW and the transmission control unit CR under the control of the CPU 2.

  On the other hand, the attachment position table TB and the work instruction data IT are recorded in the recording unit 3 in a nonvolatile manner for each work table W (in other words, for each display device D). At this time, one work instruction data IT includes content corresponding to one work instruction to be presented to the worker via the display device D of the work table W.

  Here, the mounting position table TB will be described with reference to FIG. As described above, the mounting position table TB according to the embodiment includes the identification data ID read by the reader / writer RW and the display device D on the work table W provided with the tag T in which the identification data ID is stored. It is the attachment position table containing the content which matched the attachment position data which shows the attachment position P of. That is, in the mounting position table TB illustrated in FIG. 3B, for example, the current mounting position of the display device D on the work table W provided with the tag T in which the identification data ID having the value “500000” is stored. P is shown to be the attachment position P2. Further, for example, it is indicated that the current mounting position P of the display device D on the work table W provided with the tag T in which the identification data ID having the value “500002” is stored is the mounting position P4. .

  In addition to these, the attachment position table TB according to the embodiment should be displayed using the display device D attached to the attachment position P indicated by the attachment position data on the work table W identified by the identification data ID. Work instruction data IT corresponding to the work instruction is recorded in association with the identification data ID. That is, in the mounting position table illustrated in FIG. 3B, for example, work instructions to be displayed on the display device D in the work table W provided with the tag T in which the identification data ID having the value “50,0001” is stored. It is indicated that the data IT is “work B data”. Further, for example, the work instruction data IT to be displayed on the display device D in the work table W provided with the tag T in which the identification data ID having the value “500003” is stored is “work D data”. It is shown.

  Then, the CPU 2 performs overall control of the work instruction operation according to the embodiment based on the instruction operation in the operation unit 4. Specifically, the CPU 2 refers to the mounting position table TB recorded in the recording unit 3 based on the identification data ID read by the reader / writer RW, and the work table identified by the read identification data ID. An attachment position P of the display device D at W is detected. Thereafter, the CPU 2 controls the transmission control unit CR so that the transmission unit TR is positioned at a position facing the detected mounting position P. Then, the CPU 2 sends work instruction data corresponding to the content of the work instruction to be displayed on the display device D attached to the work table W identified by the identification data ID from the transmitting unit TR located at the directly facing position. In order to transmit IT, the work instruction data IT is output to the transmission unit TR via the transmission control unit CR. As a result, the display device D in the work table W provided with the tag T in which the identification data ID is stored receives the work instruction data IT via the transmission unit TR, as will be described later. Display for presentation.

  Next, as illustrated in FIG. 3C, each display device D according to the embodiment includes a receiving unit 10, a CPU 11, a memory 13 including a nonvolatile area such as a hard disk or a ROM, and a volatile area such as a RAM. , An operation unit 12 including operation buttons or a touch panel, and a display 14 including an electronic paper display device. At this time, the receiving unit 10 corresponds to an example of a “receiving unit” according to the present invention, and the display 14 corresponds to an example of an “output unit” according to the present invention. In the following description, the CPU 11 of the display device D is simply referred to as “CPU 11”.

  In the above configuration, when the receiving unit 10 receives the work instruction data IT from the transmitting unit TR at a position facing the mounting position P of the receiving unit 10 (in other words, the display device D) under the control of the CPU 11, Is output to the CPU 11.

  Thereby, the memory 13 temporarily stores the received work instruction data IT. The CPU 11 reads the stored work instruction data IT from the memory 13 and displays it on the display 14 at the timing when the display operation is performed on the operation unit 12 or at a preset timing, for example. This display is terminated after the elapse of a predetermined time or by a display end operation or the like in the operation unit 12.

  Next, the movement of the operation unit TR by the operation control unit CR will be specifically described with reference to FIG. As illustrated in FIG. 4, the transmission control unit CR according to the embodiment includes an arm AM1, an arm AM2, a hinge unit HG, a mounting bracket HD, and a horizontal direction (for example, FIG. 4 (a) left and right direction) and a slide rail SL fixedly installed. In this configuration, the hinge portion HG connects the other end of the arm AM1 and one end of the arm AM2. The hinge part HG connects the arm AM1 and the arm AM2 so that the arm AM1 can be bent with respect to the arm AM2 in a vertical plane, for example (see the arc-shaped solid double arrow shown in FIG. 4A). ). On the other hand, the mounting bracket HD attached to the other end of the arm AM2 is on the slide rail SL in a direction parallel to the moving direction of the work table W (see the broken line arrow in FIG. 4A) (see the solid straight double arrow in FIG. 4). It can be moved. Then, the position of the mounting bracket HD facing in the direction parallel to the moving direction of the work table W and the bending of the arm AM1 including the transmission unit TR with respect to the arm AM2 are directly opposite to the position of any mounting position P. The transmission unit TR is moved. For this reason, a drive motor or the like (not shown) of the transmission controller CR controls the movement of the mounting bracket HD and the bending of the arm AM1 with respect to the arm AM2 under the control of the CPU 2 of the management server SV.

  Next, the work instruction operation in the work instruction system S according to the above-described embodiment will be described with reference to FIG.

  In the work instruction operation according to the embodiment using the display device D attached to each work table W, the CPU 2 of the management server SV, for example, when the power switch is turned on, the display device attached to the work table W. Monitoring whether the work table W has arrived at a position on the production line L where display of the work instruction in D is started (or a position on the production line L where the display of the work instruction is rewritten). Start (step S1). As the monitoring operation, for example, the switch is turned on when the wheel WH of the work table W that has moved to the position passes over the physical switch provided at the process position on the production line L. Accordingly, it can be configured to determine that the work table W has moved to the above position. Further, when the reader / writer RW installed at the position can read the identification data ID stored in one of the tags T, it is determined that the work table W has moved to the position. You may comprise as follows. When the arrival of any worktable W cannot be detected in the monitoring in step S1 (step S1; NO), the CPU 2 proceeds to determination in step S9 described later.

  On the other hand, when the arrival of any worktable W is detected in the monitoring in step S1 (step S1; YES), the CPU 2 stores it from the tag T of the worktable W where the arrival is detected. In order to read the existing identification data ID, a tag reading instruction to that effect is transmitted to the tag T (step S2). Thereafter, the CPU 2 waits for the identification data ID corresponding to the transmitted tag reading instruction to be read (step S3).

  On the other hand, in the work instruction operation according to the embodiment, when the power switch is turned on, for example, the reader / writer RW waits for transmission of the tag reading instruction from the management server SV (step S10). When the tag reading instruction is not transmitted in the monitoring in step S10 (step S10; NO), the reader / writer RW proceeds to the determination in step S13 described later. On the other hand, when a tag reading instruction is transmitted in the determination of step S10 (step S10; YES), the reader / writer RW next reads the identification data ID stored in it from the tag T within the detection range. (Step S11), this is transmitted to the management server SV (Step S12). Thereafter, the reader / writer RW determines whether or not the power switch is turned off (step S13). If the power switch is turned off (step S13; YES), the reader / writer RW is used as it is. The work instruction operation related to is terminated. On the other hand, if the power switch is not turned off in the determination in step S13 (step S13; NO), the reader / writer RW returns to the monitoring in step S10 and repeats the above-described operation.

  Next, when the identification data ID is not transmitted from the reader / writer RW in the standby in step S3 (step S3; NO), the CPU 2 proceeds to determination in step S9 described later. On the other hand, when the identification data ID is transmitted from the reader / writer RW in the standby of step S3 (step S3; YES), the CPU 2 next records the data in the recording unit 3 based on the transmitted identification data ID. The attachment position table TB is searched, and the attachment position data and work instruction data IT associated with the identification data ID are extracted. Thereby, CPU2 specifies the attachment position P of the display apparatus D attached to the work table D from which the arrival was detected in the monitoring of said step S1 based on the extracted attachment position data (step S4). Then, the CPU 2 transmits a movement instruction to that effect to the transmission control unit CR in order to move the transmission unit TR to a position directly facing the specified mounting position P (step S5). Thereafter, the CPU 2 waits until a movement end response corresponding to the transmitted movement instruction is transmitted (step S6).

  In contrast, in the work instruction operation according to the embodiment, for example, when the power switch is turned on, the transmission control unit CR waits for transmission of the movement instruction from the management server SV (step S15). When the movement instruction is not transmitted in the monitoring in step S15 (step S15; NO), the transmission control unit CR proceeds to determination in step S18 described later. On the other hand, when a movement instruction is transmitted in the determination of step S15 (step S15; YES), the transmission control unit CR next drives the drive motor (not shown) or the like based on the transmitted movement instruction. Thus, the transmitter TR is moved to the position indicated by the transmitted movement instruction (that is, the position facing the mounting position P of the display device D on the work table W that has arrived at that time) (step S16). ). Thereafter, when the movement is completed, the transmission control unit CR transmits the movement completion response to that effect to the management server SV (step S17). Thereafter, the transmission control unit CR determines whether or not the power switch is turned off (step S18). If the power switch is turned off (step S18; YES), the embodiment as the transmission control unit CR is used as it is. The work instruction operation related to is terminated. On the other hand, if the power switch is not turned off in the determination in step S18 (step S18; NO), the process returns to the monitoring in step S15 and the above-described operation is repeated.

  Next, when the movement completion response is not transmitted from the transmission control unit CR in the standby in step S6 (step S6; NO), the CPU 2 proceeds to determination in step S9 described later. At this time, the CPU 2 may stand by until a movement completion response is transmitted. On the other hand, when the movement completion response is transmitted from the transmission control unit CR in the standby of step S6 (step S6; YES), the CPU 2 then completes the movement by the transmitted movement completion response. A so-called polling operation for confirming the position of the display device D that should be facing the transmitter TR is performed (step S7). In this polling operation, transmission of polling data through the transmission unit TR is performed one or more times until a polling response from the display device D is received. When the position confirmation of the display device D by the polling operation is completed due to the reception of the polling response, the CPU 2 then performs the attachment position table on the display device D whose position has been confirmed by the operation of step S4. Work instruction data IT extracted from TB is transmitted (step S8). The transmission of the work instruction data IT is executed via the transmission control unit CR and the transmission unit TR.

  Thereafter, the CPU 2 determines whether or not the power switch is turned off (step S9). If the power switch is turned off (step S9; YES), the work instruction according to the embodiment as the management server SV is directly performed. End the operation. On the other hand, when the power switch is not turned off in the determination in step S9 (step S9; NO), the CPU 2 returns to the monitoring in step S1 and repeats the operation described above.

  Finally, the CPU 11 of the display device D attached to each work table W in the work instruction operation according to the embodiment, for example, when the power switch is turned on, during the movement on the production line L, in the management server SV. Waiting for position confirmation by the polling operation (step S20). When position confirmation is not performed in the monitoring of step S20 (step S20; NO), the CPU 11 proceeds to determination of step S24 described later. On the other hand, when position confirmation is performed in the determination of step S20 (step S20; YES), the CPU 11 transmits the polling response to the management server SV (step S21). Next, the CPU 11 determines whether or not the work instruction data IT from the management server SV has been received (step S22). When the work instruction data IT is not received during the predetermined standby time set in advance in the determination in step S22 (step S22; NO), the CPU 11 proceeds to determination in step S24 described later. At this time, the CPU 11 may stand by until the work instruction data IT is received. On the other hand, when the work instruction data IT is received in the determination of step S22 (step S22; YES), the CPU 11 temporarily stores the received work instruction data IT in the memory 13, and thereafter the display operation on the operation unit 12 described above is performed. At the set timing or preset timing, a work instruction corresponding to the stored work instruction data IT is displayed on the display 14 (step S23). The display of the work instruction is ended after a predetermined time has elapsed as described above, or by a display end operation or the like in the operation unit 12.

  Thereafter, the CPU 11 determines whether or not the power switch of the display device D is turned off (step S24), and when the power switch is turned off (step S24; YES), the embodiment as the work table W is performed as it is. This work instruction operation is terminated. On the other hand, when the power switch is not turned off in the determination in step S24 (step S24; NO), the CPU 11 returns to the monitoring in step S20 and repeats the operation described above.

  As described above, according to the operation of the work instruction system S according to the embodiment, when the work table W has moved to the position where the work instruction should be displayed, the work instruction system S moves to the position of the display device D indicated by the attachment position data. The transmission unit TR is moved to a corresponding position, the work instruction is transmitted, and is displayed on the display device D. Therefore, even with respect to the display device D having a plurality of types of positions in relation to the work table W that moves together, the relative positional relationship between the transmission unit TR and the reception unit 10 of the display device D is maintained and the reliability is ensured. In addition, the work instruction data IT can be stably transmitted, and the work instruction corresponding to the data can be displayed on the display device D.

  At this time, when an electronic paper display device is used as the display medium in the display 14 of the display device D, the electronic paper display device itself is a display device that does not consume power except when the display content is rewritten. This can contribute to reduction of power consumption in the entire S.

  Further, when the work table W has moved to a position where the work instruction should be displayed, the work table W has moved by detecting the identification data ID from the tag T provided on the work table W via wireless communication. When it is detected that the work table W on which the work instruction is to be displayed can be easily detected, the necessary work instruction can be reliably displayed on the display device D of the necessary work table W. Can do.

  Furthermore, since the work instruction data IT is transmitted and received between the transmission unit TR and the reception unit 10 by the short-range wireless communication method, the work instruction data IT can be transmitted and received at high speed and reliably while maintaining predetermined integrity. It can be carried out.

  Furthermore, since the transmitter TR is moved to a position corresponding to the position of the display device D indicated by the mounting position data corresponding to the work table W that has moved to the position where the work instruction should be displayed, wireless communication is performed. It is possible to transmit / receive work instruction data IT by reliably moving the transmission unit TR to the position to be transmitted.

  The work instruction data corresponding to the work instruction IT is previously recorded in the recording unit 3 of the management server SV, and is acquired from an external distribution server (not shown) every time the display on the work table W is rewritten. You may comprise.

  Further, a program corresponding to the flowchart shown in FIG. 5 is recorded on a recording medium such as an optical disk, or is acquired and recorded from a network such as the Internet, and is read by a general-purpose microcomputer or the like. When executed, the microcomputer or the like may be configured to function as the CPU 2 and the CPU 11 and the transmission control unit CR according to the embodiment.

  As described above, the present invention can be used in the field of work instruction systems, and is particularly applicable to the field of work instruction systems for instructing work contents to workers in each process in a production line by so-called flow work. In particular, a remarkable effect can be obtained.
