Description

  The present invention relates to a technique for guiding a work procedure to an operator at a production site.

  A system that supports inspection work in a production line is known (for example, Patent Document 1). The support system of Patent Document 1 displays a guidance screen indicating an in-process (or product) inspection procedure, and accepts input of inspection results performed by an operator according to the guidance screen. Then, the support system determines whether or not the received inspection result is within the allowable range of quality, and notifies the operator of the quality abnormality when determining that the inspection result does not fall within the allowable range.

  Thus, according to Patent Document 1, since the support system automatically determines the quality of work-in-progress (or product), even an operator with a low work proficiency can perform an accurate inspection.

JP-A-11-156680

  By the way, if the work in progress (or product) is judged to be abnormal as a result of inspection at the production site, discarding the work in progress (or product) is from the viewpoint of environmental protection and effective use of resources. It is not preferable.

  There are various work contents to be repaired depending on the inspection part and the inspection result of the work in progress. For example, when the inspection result is greatly deviated from a predetermined allowable range, it may be necessary to return to the process before the inspection process and start over from the work of the process. Some inspections can be handled by fine adjustment of a portion to be inspected. For this reason, in order to increase productivity at the production site, an operator who performs reworking needs to thoroughly examine the inspection portion and the inspection result and take appropriate measures.

  However, although the said patent document 1 can notify an operator of abnormality of an inspection result, it does not consider especially the rework work of the work-in-process item (or product) judged to be abnormal by inspection. In Patent Document 1, it is necessary for an operator to determine by himself where the rework work is to be performed. Therefore, in Patent Document 1, the operator may not be able to accurately determine the rework work to be performed. For example, when an operator mistakenly determines the identification of a rework, a quality defect may occur as a result. In addition, for example, an operator may spend too much time to specify a rework work and increase the lead time. Thus, in the said patent document 1, productivity of a product may be reduced.

  Accordingly, an object of the present invention is to increase the productivity of products in a production site such as a factory.

  In order to solve the above-described problems, one embodiment of the present invention is applied to a guidance terminal that includes a display unit and displays a guidance screen that indicates a work procedure of work for producing a product on the display unit.

  The work guidance terminal stores first storage means for storing data for displaying the guidance screen and data indicating work to be performed in advance in association with the inspection result of the work in progress of the product. Second storage means, means for receiving the input of the inspection result, means for specifying work to be performed next using the received inspection result and the data stored in the second storage means; Reading data for displaying a guidance screen indicating the work procedure of the identified work from the first storage means, and displaying the guidance screen on the display unit using the read data.

  As described above, according to this aspect, the guidance terminal uses the received inspection result and the data stored in advance indicating the work to be performed in advance in association with the inspection result. To identify. Therefore, according to this aspect, it is not necessary for the operator to determine by himself where the rework work is to be performed. Therefore, according to this one aspect | mode, it can prevent that an operator corrects it accidentally. Further, with this configuration, it is possible to cause the worker to rework efficiently.

  The data indicating the work to be performed in advance in association with the inspection result may be data indicating the work to be performed next in the production of the product and data indicating the work already performed. Further, the means for specifying the work to be performed next may specify the work of the next process of the inspection when satisfying a predetermined reference value.

  By configuring in this way, it is possible to display a guidance screen indicating the procedure of the work already performed according to the inspection result. Therefore, for example, even if the worker who performed the inspection is not in charge, the worker who performed the inspection can correct it. In this case, since it is not necessary to return the work in progress of the product to the previous person in charge, it is possible to reduce the work and time required to carry the work in progress.

  The data indicating the work procedure to be performed in advance in association with the inspection result includes data indicating the work to be performed next in the production of the product, data indicating the work already performed, and data indicating the work to redo the inspection. It is good also as being.

  With this configuration, it is possible to display a guidance screen indicating the procedure of the inspection rework work according to the inspection result. Therefore, when the received inspection result is an input error or an inspection error, it is possible to prevent erroneous guidance due to the error.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, a first embodiment of the present invention will be described.

  FIG. 1 is a diagram for explaining the outline of a work guidance system according to the first embodiment of the present invention. In the following description, a case where the work guidance system of the first embodiment is used for a production line provided in a factory is taken as an example.

  First, a brief description of the production line will be given. As illustrated, the factory 1000 is provided with production lines L1 to Ln. In the production lines L1 to Ln, products (for example, printers) that are completed through a plurality of work processes are produced. In the present embodiment, the “work process” refers to a collection of at least one work element. The “work process” in the present embodiment mainly refers to an assembly process, and the “work process” includes an “inspection process”. In the “inspection process” of the present embodiment, a process for inspecting the quality of a work in progress (or product) such as confirmation of the position of the attached part (for example, a process for inspecting whether the position of the attached part is normal) ) And a process for measuring the characteristics of a work-in-progress product and a predetermined location (for example, measuring a predetermined location of the work-in-progress product and determining the next process based on the measurement value) Shall be included.

  The production lines L1 to Ln are divided into a plurality of work positions P1 to P5 for performing work. The plurality of work processes are divided and assigned to positions. For example, when a product is completed through 50 work steps, one or more work steps are assigned to each work position P1 to P5 so that there are 50 steps as a whole.

  In addition, in this embodiment, although the case where the production lines L1-Ln are divided | segmented into five positions P1-P5 is made into an example, this is only an illustration. In FIG. 1, all of the production lines L1 to Ln are divided into five positions P1 to P5, but this is merely an example. The number of positions may vary from production line to production line.

  Each work position P1 to P5 is provided with a parts place 200 in which parts used for work performed at each work position P1 to P5 are arranged. As the parts to be arranged, there are various elements constituting the product to be produced. For example, a mechanical component, an actuator, a sensor, a circuit, a board, a wiring material, a circuit component, a housing, a connecting component, and the like can be given.

  In addition, each work position P1 to P5 is provided with a tool table 300 for storing a tool (such as a torque driver) used in each work position. Further, a moving work table 700 is placed at each work position P1 to P5, and work-in-progress products according to work procedures are placed on the moving work table.

  The worker performs the work divided for each position at each work position P1 to P5, and when the work is completed, the work piece placed on the moving work table is moved to the downstream work position. Then, each work is sequentially performed toward the work positions P1 to P5, and one product is completed when the work process assigned to P5 is completed. At this stage, it may be an intermediate product. In that case, the intermediate product is a finished product in this line.

  Then, the work guidance system of this embodiment provided in the production lines L1-Ln is demonstrated. As shown in the figure, the work guidance system of this embodiment includes a work guidance terminal 100 (simply referred to as “guidance terminal 100”) installed at each work position P1 to P5 of the production lines L1 to Ln, and a management server 500. And have. Further, the guidance terminal 100 and the management server 500 are connected via the network 600.

  The guidance terminal 100 displays a guidance screen for instructing a work procedure for each work process of products produced on the production lines L1 to Ln. The guidance terminal 100 has an input device (see FIG. 2), and receives input of data indicating the end of the work process input by the user via the input device. When the guidance terminal 100 receives the input from the worker, the guidance terminal 100 changes the displayed guidance screen to a guidance screen for a work process to be performed next.

  In addition, the guidance terminal 100 displays a guidance screen showing the procedure of the work-in-process inspection process. The worker performs work according to the guidance screen for the inspection process. The work guidance terminal 100 receives an input of the inspection result of the inspection via the input device (see FIG. 2). The work guidance terminal 100 changes the guidance screen to be displayed according to the received inspection result.

  The management server 500 manages the work progress status of work-in-progress produced on the production lines L1 to Ln. Specifically, the management server 500 includes a “product identifier” that is a unique identifier that identifies work-in-progress produced on the production lines L1 to Ln from each guidance terminal 100, and “data indicating a completed process”. Is received and stored ("data indicating completed process" will be described later). In addition, the management server 500 receives an inquiry regarding work progress of a work in progress with a predetermined “product identifier” from the guidance terminal 100 (accepts via the network 600). The management server 500 checks the work progress of the accepted work in progress and transmits data indicating the checked work progress to the guidance terminal 100.

  Next, the hardware configuration of the work guidance system according to the first embodiment will be described with reference to FIG.

  FIG. 2 is a diagram illustrating a hardware configuration of the work guidance system according to the present embodiment.

  First, the hardware configuration of the guidance terminal 100 will be described. The guidance terminal 100 includes a computer 110, a display device 150, and an input device 160.

  The computer 110 includes a CPU (Central Processing Unit) 120 that executes a program, a main storage device 130 that temporarily stores programs and data executed by the CPU 120, and a hard disk that stores programs executed by the CPU 120 in advance. And an auxiliary storage device 111 such as an I / O interface (I / F) 140 that controls transmission / reception of data to / from an external device.

  In the auxiliary storage device 111, various programs (not shown) for controlling the computer 100, programs for realizing various functions of the work guidance terminal 100 (guidance program 112, inspection determination program 113, and communication control program 114). ) And data used for various processes (for example, “reference value” used for an inspection determination process described later). The auxiliary storage device 111 may store data indicating the in-process inspection result. Various functions of the work guidance terminal 100 will be described later.

  The display device 150 is a unit that displays image data output from the computer 110, and includes a CRT, a liquid crystal display, or the like.

  The input device 160 is a unit that accepts instructions from the user such as selecting various functions of the guidance terminal 100 and accepting work process completion. One or more devices such as a hard switch such as a scroll key and a foot button, a joystick, and a touch panel pasted on the display device 150 are applied to the input device 160 as necessary. Further, as the input device 160, a barcode reader may be used alone or in combination with other devices.

  The guidance terminal 100 may be connected to an electronic measuring device having a function of outputting measured values as electronic data to an external device. By comprising in this way, the input mistake of an operator's test result can be prevented.

  The network 600 is a network that connects the guidance terminal 100 and the management server 500. For example, a factory LAN (Local Area Network) can be used for the network 600. In the illustrated example, the network 600 is illustrated as a wired network, but the network may be wireless.

  The management server 500 stores in advance a CPU (Central Processing Unit) 530 that executes programs, a main storage 540 that temporarily stores programs and data executed by the CPU 530, programs that are executed by the CPU 530, and the like. A computer system having an auxiliary storage device 510 such as a hard disk and an I / O interface (I / F) 520 that controls transmission / reception of data to / from an external device can be used. The management server 500 may be connected to an input device (not shown) such as a keyboard and a mouse and a display device (not shown) such as a liquid crystal display.

  The auxiliary storage device 510 includes various programs (not shown) for controlling the management server 500, programs for realizing various functions of the work guidance terminal 100 (work management program 511, communication control program 513), work management. An operation result file 512 used by the program and an inspection result file (not shown) for managing the inspection result of work-in-progress are stored.

  The auxiliary storage device 510 may store data used for various processes performed by the guidance terminal 100 (for example, “reference value” used for examination determination described later). Then, data used for the various processes is transmitted from the management server 500 to each guidance terminal 100. In this way, it is possible to reduce time and labor when changing data used for various processes performed by the guidance terminal 100.

  Next, the functional configuration of the work guidance system according to the first embodiment will be described with reference to FIG. 3 and FIGS.

  FIG. 3 is a functional block diagram of the guidance system according to the first embodiment. 5 to 6 are diagrams illustrating examples of guidance screens displayed by the guidance terminal 100 according to the present embodiment.

  First, the functional configuration of the gain dance terminal 100 will be described. As illustrated in FIG. 3, the computer 110 includes an examination determination unit 180, a communication control unit 181, and a guidance display unit 182.

  The communication control unit 181 manages data transmission / reception with the management server 500. The communication control unit 181 receives data transmitted from the management server 500 and transmits the data to the guidance display unit 182. Further, the communication control unit 181 receives data output from the guidance display unit 182 and outputs the data to the management server 500.

  The guidance display unit 182 displays on the display device 150 a guidance screen that shows the procedure of the work process of products produced on the production lines L1 to Ln. Specifically, the guidance display unit 182 is configured to be able to display guidance screens for all “work processes” necessary for completing products produced on the production lines L1 to Ln. That is, the work guidance terminal 100 displays the “work process” assigned to its own position and the work process guidance screen assigned to positions other than its own, regardless of the position (P1 to P5). Can be displayed.

  Here, an example of the above guidance screen will be described with reference to FIGS.

  FIG. 5 shows a guidance screen 50 for “height adjustment work process”, and FIG. 6 shows a guidance screen 60 for “inspection process”. As illustrated, the screen 50 (or 60) includes an area 51 (61) for displaying “process name”, an area 52 (62) for displaying “overall view”, and an area 53 (for displaying “work procedure”). 63), an area 54 (64) for displaying “attached parts and jigs / tools to be used”, an area 55 (65) for displaying “assembly image”, and an area 56 (66) for displaying “confirmation items”. doing.

  Then, the operator recognizes that the work process to be performed from the display of the area 51 is the “work process for adjusting the height of the carriage mechanism”. The operator can confirm the “work procedure” to be performed in the displayed process from the display in the area 53. The region 53 is provided with a completion confirmation button 53a for receiving confirmation of completion of the work process shown on the screen 50. Further, the operator can grasp the work image from the “overall view” in the area 52 and the “assembly image” in the area 55, and can confirm the parts, jigs, and tools to be used from the display in the area 54. .

  As described above, the guidance display unit 182 displays the procedure of the work process for each work process, so that the worker can be guided to the work according to the correct work procedure.

  Returning to FIG. 3, the description of the guidance display unit 182 is continued. After being activated, the guidance display unit 182 acquires the “product identifier” of the work in progress via the input device 160. Note that the “product identifier” in the present embodiment may be used for a production number or the like. Further, the “product identifier” acquisition unit performed by the input device 160 is not particularly limited. For example, a “product identifier” sticker displayed in advance as a bar code is attached to the work in progress. Then, a barcode reader may be connected to the computer 110 so that the “product identifier” is acquired by the barcode reader.

  After acquiring the “product identifier”, the guidance display unit 182 requests the management server 500 to confirm the work progress of the work in progress of the acquired “product identifier” (via the communication control unit 181). The guidance display unit 182 receives data indicating the work progress status transmitted from the management server 500 in response to the work progress confirmation request. The guidance display unit 182 identifies a guidance screen to be displayed according to the received data indicating the work progress status, and displays the identified guidance screen on the display device 150.

  Further, the guidance display unit 182 receives data indicating the end of the work process input by the worker via the input device 160. The guidance display unit 182 changes the guidance screen displayed when the input from the worker is received to the guidance screen for the next work process.

  Furthermore, when the guidance display unit 182 receives data indicating the completion of the above-described work process, the guidance display unit 182 transmits “update request for process already completed” to the management server 500. Specifically, the guidance display unit 512 transmits “worked process update request data” including the “product identifier” of the work process and work-in-process for which the termination has been received (processing of the management server 500 is performed). Will be described later).

  In addition, for example, when a guidance screen for “inspection process” as illustrated in FIG. 6 is displayed, the guidance display unit 182 receives an inspection result input by the operator via the input device 160. When the guidance display unit 182 receives the inspection result, it outputs “data indicating the work process displayed on the guidance screen” and “accepted inspection result” to the inspection determination unit 180. Furthermore, when the guidance display unit 182 receives the inspection result, the inspection result including the “product identifier” of the work in progress, “data indicating the work process displayed on the guidance screen”, and “accepted inspection result”. Data is transmitted to the management server 500. The guidance display unit 182 may store the received inspection result in a predetermined area of the auxiliary storage device 111 in association with the “product identifier” of the work in progress.

  The inspection determination unit 180 receives the “data indicating the work process” and the “inspection result” output from the guidance display unit 182 and changes the guidance screen to be displayed on the guidance display unit 182 according to the received data. Let

  Specifically, the inspection determination unit 180 holds a “reference value” for determining whether the inspection result performed in the inspection process is acceptable in terms of quality. The inspection determination unit 180 determines that the inspection portion is normal when the inspection result satisfies the “reference value”. On the other hand, the inspection determination unit 180 determines that there is an abnormality in the inspection portion when the inspection result does not satisfy the “reference value”.

  The “reference value” is predetermined for each inspection process, and the inspection determination unit 180 holds a plurality of types of “reference values” in association with each inspection process. Further, the inspection determination unit 180 holds determination information (not shown) in which data for specifying the work process to be reviewed when the inspection result does not satisfy the “reference value” is stored. Note that the data for specifying the work process is stored so as to indicate a table structure, for example. Further, the determination information stores data for specifying the review work process for each inspection process.

  The inspection determination unit 180 receives the work process data and the inspection result output from the guidance display unit 182 and specifies a “reference value” used for determination from the received work process. The inspection determination unit 180 compares the specified “reference value” with the acquired inspection result, and determines whether or not the inspection result satisfies the “reference value”.

  When the inspection determination unit 180 determines that the “reference value” is satisfied, the inspection determination unit 180 instructs the guidance display unit 182 to display a guidance screen for a work process to be performed next to the inspection process. On the other hand, when it is determined that the “reference value” is not satisfied, the inspection determination unit 180 specifies the review process according to the determination information (not illustrated), and the specified review is performed on the guidance display unit 182. Instructs the display of the guidance screen for the work process.

  Next, the functional configuration of the management server 500 will be described. The management server 500 includes a communication control unit 580 and a work management unit 581.

  The communication control unit 580 manages data transmission / reception performed with the guidance terminal 100. Communication control unit 500 accepts data transmitted from guidance terminal 100 and transmits the data to work management unit 581. In addition, the communication control unit 580 receives data output from the work management unit 581 and outputs the data to the guidance terminal 100.

  The work management unit 581 manages the work progress status of the work in progress produced in the production lines L1 to Ln using the data of the work record file stored in the management server 500.

Here, the data structure of the work record file 512 will be described. The work performance file 512 includes an entry 513 for storing the “product identifier” of the work-in-progress product, and an entry 514 for storing “process status” indicating the most recently completed process of the “product identifier” stored in the entry 513. Have.

  In the illustrated example, “AB0001” and “AB0002” are stored in the entry 513, and “P4-8” and “P3-3” are stored in the entry 514 associated with the entry 513. This indicates that the work-in-process having the “product identifier” of “AB0001” has been completed up to “work process 8” assigned to position 4. Further, it is shown that the work in progress having the “product identifier” of “AB0002” has been completed up to the work of “work process 3” assigned to the position 3.

  When the work management unit 581 receives the “work progress confirmation request” of the work in progress having the “product identifier” transmitted from the work guidance terminal 100, the work management unit 581 uses the data of the work result file 512 to display the “product identifier”. The “process status” of work in process having The work management unit 581 transmits data indicating the specified “process status” to the work guidance terminal 100. In the illustrated example, when the work management unit 581 receives a “work progress confirmation request” for a work in progress having a “product identifier” of “AB0001”, “P4” of “process status” is received from the work performance file 512. -8 "is specified, and data indicating" P4-8 "is transmitted to the guidance terminal 100.

  Further, the work management unit 581 receives “work completed process update request data (data including“ product identifier ”of work in progress and work process in which the work in progress has been completed)” transmitted from the guidance terminal 100. Then, the work management unit 581 updates the data of the work record file 512 based on the received “work completed process update request data”. For example, in the illustrated case, it is assumed that the work management unit 581 receives “work completed process update request data” whose “product identifier” is “AB0002” and whose completed process is “P3-4”. . In this case, the work management unit 581 updates the data “P3-3” of the entry 514 corresponding to “AB0002” stored in the entry 513 of the work record file 512 to “P3-4”.

  Furthermore, the work management unit 581 manages inspection results for each work in process. Specifically, the work management unit 581 receives the inspection result data (data including “product identifier”, “data indicating work process”, and “accepted inspection result” of the work in progress) transmitted from the guidance terminal 100). Receive. Using the received inspection result data, the work management unit 581 stores “inspection process” and “inspection result” in the inspection result file in association with the work in progress (“product identifier” of the work in progress).

  Subsequently, a display process of a guidance screen for a work process performed by the guidance terminal 100 according to the present embodiment will be described with reference to FIGS. In the following description, at the position P5 of the production lines L1 to Ln, the worker starts from the operation of “adjustment step A (P5-3 (third step of position P5))” assigned to the position 5. The case will be described as an example, but this is merely an example.

  FIG. 4 is a flowchart of the guidance screen display process of the work guidance terminal 100. 7 to 9 are diagrams illustrating the guidance screens displayed by the work guidance terminal 100 according to the present embodiment, as in FIGS. 5 and 6 described above.

  After being activated, the guidance display unit 182 of the guidance terminal 100 acquires the “product identifier” of the work in progress via the input device 160, displays a guidance screen for the work process in which the work in progress starts, and in S2. The process proceeds (S1).

  Specifically, the guidance terminal 100 requests the management server 500 to confirm the work progress of the work in progress of the acquired “product identifier”. The guidance display unit 182 receives data indicating the work progress status returned from the management server 500 in response to the work progress confirmation request. Then, the guidance display unit 182 specifies a guidance screen to be displayed in accordance with the received data indicating the work progress status.

  For example, it is assumed that the guidance display unit 182 receives “P5-2 (second process at position P5)” as data indicating the work progress status (“process status” indicating the latest work completed process). In that case, the guidance display unit 182 specifies “P5-3”, which is the next process after “P5-2”, as the work process to start work. And the guidance display part 182 displays the guidance screen (screen 50 of FIG. 5) which shows the procedure of identified "P5-3".

  In S <b> 2, the guidance display unit 182 displays a guidance screen for the process of “Adjustment Process A (P5-3)” until accepting an input of work completion from the worker. When the guidance display unit 182 receives an input for completion of work, the guidance display unit 182 changes the displayed guidance screen to a screen (not shown) that displays a procedure of “assembly process A (P5-4)” to be performed next. In addition, the guidance display unit 182 performs a process of transmitting “work completed process update request data” to the server 500 when performing the process of changing the guidance screen. Then, the server 500 updates the work result file 514 using the “product identifier” and the “work process (P5-4)” included in the “worked process update request data”.

  In S3, the guidance display unit 182 performs the same process as in S2. Specifically, the guidance display unit 182 receives an input of work completion and changes the displayed guidance screen to data indicating the procedure of the work process to be performed next. Further, when performing the above-described guidance screen changing process, the guidance display unit 182 transmits “work completed process update request data” to the server 500 and causes the server 500 to update the work record file 514. The guidance screen to be changed here is a guidance screen (screen 60 in FIG. 6) of “inspection step A (carriage mechanism height adjustment)”.

  On the screen 60, the work procedure of the inspection process A is displayed in a region 63 indicating “work procedure”, and a schematic diagram 69 showing the measurement position is displayed. For this reason, the guidance terminal 100 can cause the operator to inspect the correct procedure.

  In S4, the guidance display unit 182 receives an input of “confirmation of work contents (confirmation button 68 on the screen 60)” and displays a guidance screen (for example, the screen 70 in FIG. 7) that accepts the input of the inspection result performed in the inspection process. indicate. When the guidance display unit 182 receives an input of the inspection result, the guidance display unit 182 proceeds to the process of S5.

  On the screen 70, an area 71 for displaying “process name”, an area 72 for displaying “overall view”, and an area 76 for accepting input of inspection results are displayed. An area 76 displays a schematic diagram 75 in which three measurement positions are numbered and an inspection result input area 74. Further, the numbers shown in the schematic diagram are shown in the inspection result input fields 74a, b, and c in the input area 74. In the illustrated example, the measurement value (inspection result) at the measurement position indicated by “No. 1 (2, 3)” in FIG. 75 is input to the input column 74 a (b, “No. 1 (2, 3)” in the input area 74. It guides you to input in c). By displaying in this way, it is possible to prevent an operator from entering errors in the inspection result.

  Note that the screen 70 shows an example of a screen in the case where the input of the inspection result data is received via the input device 160 such as a keyboard, but this is merely an example. For example, an electronic measurement device (a device that can output a measurement value as electronic data to an external device) is connected to the computer 110 of the guidance terminal 100. The guidance display unit 182 displays a guidance screen that accepts input from the electronic measurement device. And the guidance display part 182 may receive the data of the measured value which an electronic measuring device outputs as a test result.

  In S5, the guidance terminal 100 determines whether or not the inspection result received in S4 is within an acceptable range in quality. Specifically, the guidance display unit 182 outputs the inspection result received in S4 to the inspection determination unit 180 together with data indicating the work process displayed on the guidance screen.

  The inspection determination unit 180 receives the work process data and the inspection result output from the guidance display unit 182 and specifies a “reference value” used for determination from the received work process. The inspection determination unit 180 compares the specified “reference value” with the acquired inspection result, and determines whether or not the inspection result satisfies the “reference value”.

  If it is determined that the predetermined “reference value” is satisfied, the inspection determination unit 180 instructs the guidance display unit 182 to display a guidance screen for a work process to be performed next to the inspection process, and the process proceeds to S7. In addition, when performing the instructed process, the inspection determination unit 180 outputs data indicating that the inspection process of S3 is completed to the guidance display unit 182.

  On the other hand, when it is determined that the predetermined “reference value” is not satisfied, the inspection determination unit 180 specifies a review work process according to the determination information (not illustrated) described above. In addition, although the process of the review work to be specified varies depending on the inspection process, here, a case where the process returns to S1 when the predetermined “reference value” is not satisfied is taken as an example. Specifically, the inspection determination unit 180 outputs data for instructing the guidance display unit 182 to display the guidance screen for the specified review work process (“P5-3”), and proceeds to the process of S6.

  In S <b> 6, the guidance display unit 182 receives the above instruction from the examination determination unit 180. The guidance display unit 182 displays a guidance screen indicating that the inspection target part of the inspection performed in S3 is defective, and the process returns to S1. In S6, the guidance display unit 182 also transmits “work completed process update request data” to the server 500 and performs a process of updating the work record file 514 of the server 500 (“process status” of the work record file 514). Is updated to the accepted work process “P5-3”).

  Subsequently, the process of S7 that is performed when it is determined in S5 that the predetermined “reference value” is satisfied will be described.

  In S7, the guidance display unit 182 receives an instruction to display a guidance screen output from the inspection determination unit 180 and data indicating completion of the inspection process in S3. The guidance display unit 182 displays a guidance screen according to the received instruction. In S <b> 7, the guidance display unit 182 transmits “work completed process update request data” to the server 500 and performs a process of updating the work record file 514 of the server 500.

  The guidance screen displayed in S7 is a screen showing a procedure of “inspection process B (cutter height adjustment)” for inspecting a part different from the inspection process in S3 (screen 80 in FIG. 8). Further, the screen 80 is provided with an area 83 indicating the procedure of the inspection process and an input area 81 for receiving an input of the inspection result. In S <b> 7, the guidance display unit 182 displays the screen 80 until accepting the input of the inspection result. When the guidance display unit 182 receives an input of the inspection result, the guidance display unit 182 proceeds to the process of S8.

In S8, the guidance terminal 100 determines whether or not the processing is the same as that in S5, that is, whether or not the inspection result received in S7 is within an acceptable range in terms of quality. When it is determined that the predetermined “reference value” is satisfied, the inspection determination unit 180 instructs the guidance display unit 182 to display a guidance screen for a work process to be performed next to the inspection process, and the process proceeds to S10. . In addition, when performing the above-described processing, the inspection determination unit 180 outputs data indicating that the inspection process displayed on the guidance screen in S7 is completed to the guidance display unit 182.

  On the other hand, when it is determined that the predetermined “reference value” is not satisfied, the inspection determination unit 180 specifies a review work process according to the determination information (not illustrated) described above. Here, the case where the work process which adjusts an inspection location is specified as an example of the review work process is taken as an example. The inspection determination unit 180 outputs data instructing the guidance display unit 182 to display the guidance screen of the specified review work process (work process for adjusting the inspection location), and proceeds to the process of S9.

  In S <b> 9, the guidance display unit 182 receives the above instruction from the examination determination unit 180. The guidance display unit 182 displays the guidance screen indicating that the inspection location adjustment work performed in S7 is necessary (screen 89 in FIG. 8). Then, when the guidance display unit 182 receives an input of the confirmation button 84 on the screen 89 from the operator, the guidance display unit 182 displays a guidance screen (for example, the screen 90 in FIG. 9) indicating the procedure of the work process for adjusting the inspection location. .

  When the guidance display unit 182 receives an input of completion of the review work shown on the screen 90, the guidance display unit 182 returns to the display process of S7 and displays the guidance screen 80.

  On the other hand, the process of S10 that is performed when it is determined in S8 that the predetermined “reference value” is satisfied will be described.

  In S10, the guidance display unit 182 receives an instruction to display a guidance screen output from the inspection determination unit 180 and data indicating that the inspection process in S7 is completed. The guidance display unit 182 changes the guidance screen according to the received instruction. Further, in S <b> 7, the guidance display unit 182 transmits “work completed process update request data” to the server 500 and performs a process of updating the work record file 514 of the server 500.

  Thus, according to the first embodiment, as shown in the above S5 and S8, the work guidance screen corresponding to the inspection result accepted for each inspection process is displayed. Therefore, according to the first embodiment, it is possible to cause the worker to perform a process corresponding to the inspection result.

  In the first embodiment, when the result of the inspection is abnormal, a corresponding rework work guidance screen is displayed. Therefore, according to the first embodiment, when reworking is necessary, appropriate reworking work can be guided to the operator, and as a result, productivity can be improved.

  In the first embodiment, the work guidance terminal 100 is assigned to the “work process” assigned to its own position and to a position other than itself, regardless of the position (P1 to P5). It is configured to be able to display a guidance screen of a working process.

Therefore, for example, even when the necessary rework process is different from the work process in charge of the worker who performed the inspection, the guidance display indicating the work procedure of the process can be performed. With this configuration, even if the reworking is a different work, the worker who performed the inspection can make the reworking. Therefore, according to the first embodiment, it is not necessary to return the work in process to the previous person in charge (position), and the work in progress of the work in progress and its time can be reduced. Thus, according to the present embodiment, product productivity can be improved at a production site such as a factory.

  Subsequently, a second embodiment of the present invention will be described.

  In the second embodiment, a function for preventing an inspection error and an input error of an inspection result is further added to the work guidance apparatus 100 of the first embodiment.

  The schematic configuration and hardware configuration of the second embodiment of the present invention are the same as those of the first embodiment shown in FIGS. The functional configuration of the second embodiment is the same as that of the first embodiment shown in FIG. 3 except that the work guidance screen display process performed by the guidance terminal 100 is different. Therefore, in the following, a display process of a work guidance screen, which is different from the first embodiment, will be described with reference to FIG.

  In S24, the guidance terminal 100 determines whether or not the inspection result received in S23 is within an acceptable range in quality.

  In the second embodiment, the inspection determination unit 180 preliminarily inputs a “first reference value” for determining whether or not the inspection result is in an acceptable range in quality, and an inspection error or an inspection result is erroneously input. It holds “second reference value” for determining whether or not there is.

  Then, the inspection determination unit 180 determines that the quality of the inspection target part is normal when the inspection result satisfies the “first reference value”. On the other hand, when the inspection result does not satisfy the “first reference value”, the inspection determination unit 180 determines that there is an abnormality in the inspection target portion. Further, the inspection determination unit 180 determines that the inspection result does not correspond to either an inspection error or an erroneous input of the inspection result when the inspection result satisfies the “second reference value”. On the other hand, when the inspection result does not satisfy the “second reference value”, the inspection determination unit 180 determines that it is an inspection error or an erroneous input of the inspection result. In the present embodiment, the specific numbers of the “first reference value” and the “second reference value” are not particularly limited.

Then, when the inspection result does not satisfy the first reference value (or the second reference value), the inspection determination unit 180 uses the first determination information (or the second determination information) to correct the work process. Is identified.

  Specifically, in S24, the inspection determination unit 180 receives the work process data and the inspection result output from the guidance display unit 182 and uses two reference values (first and second) used for determination from the received work process. The reference value). The inspection determination unit 180 compares the specified “first reference value” with the acquired inspection result, and determines whether or not the inspection result satisfies the “first reference value”.

  If the “first reference value” is satisfied, the inspection determination unit 180 outputs that the inspection target portion is normal to the guidance display unit 182 and proceeds to S26. And in S26, the guidance display part 182 performs the process similar to S7 shown in FIG. 4 mentioned above. In addition, after S26, since the process similar to S8-S10 of FIG. 4 is performed, description here is abbreviate | omitted.

  On the other hand, in S24, when the inspection determination unit 180 determines that the “first reference value” is not satisfied, the process proceeds to S25.

  In S25, the inspection determination unit 180 determines whether the acquired inspection result satisfies the “second reference value”. When it is determined that the “second reference value” is satisfied, the inspection determination unit 180 uses the “first determination information” to specify the process of the rework operation (if it does not correspond to an inspection error or an erroneous input of the inspection result) Because it was judged). The inspection determination unit 180 outputs data instructing the guidance display unit 182 to display the guidance screen of the identified review work process, and the process proceeds to S28. Here, the review work process is “adjustment process A” displayed in S20.

  In S <b> 28, the guidance display unit 182 receives data instructing display of the guidance screen output from the examination determination unit 180. The guidance display unit 182 displays a screen indicating that the inspection target part performed in S22 is defective, and returns to S20 indicating the procedure of the instructed review operation.

  On the other hand, in S25, when the inspection determination unit 180 determines that the inspection result does not satisfy the “second reference value”, the inspection determination unit 180 uses the “second determination information” to specify the rework process. The inspection determination unit 180 outputs data instructing the guidance display unit 182 to display a guidance screen for the specified review work process, and the process proceeds to S27. Here, the review process is the “inspection process A” displayed in S22 (because it is determined that an inspection error has been made in inspection A or an erroneous input of the inspection result).

  In S <b> 27, the guidance display unit 182 receives data instructing display of the guidance screen output from the examination determination unit 180. The guidance display unit 182 displays a guidance screen that instructs reexamination of the examination displayed in S22, and returns to the process of S22.

  As described above, in the second embodiment, a “second reference value” for determining whether an inspection error or an inspection result is an erroneous input is provided, and an inspection error and an erroneous input of the inspection result are determined. ing. Therefore, according to the second embodiment, it is possible to prevent an erroneous work guidance screen from being displayed due to an inspection error and an erroneous input of an inspection result, and as a result, it is possible to improve product productivity. .

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the gist of the present invention. For example, in the above description, the present embodiment has been described by taking an example in which the present embodiment is applied to a production line in a factory. 500 may be provided.

  In the present embodiment, the case where the inspection determination unit 180 and the guidance display unit 182 are provided in the guidance terminal 100 has been described. However, the present invention is not particularly limited thereto. For example, the examination determination unit 180 and the guidance display unit 182 may be provided on the management server 500 side so that a guidance screen is supplied from the management server 500 to the work guidance terminal 100. Alternatively, a dedicated server having the inspection determination unit 180 and the guidance display unit 182 may be connected on the network 600 so that the guidance screen is supplied from the dedicated server to the work guidance terminal 100.

  In the present embodiment, the case where the management server 500 is connected to the work factory terminal 100 in the same factory 1000 via the LAN has been described as an example, but this is only an example. For example, the management server 500 may be connected to the outside of the factory 1000 and connected to the work guidance terminal 100 via an external network (a dedicated line or the Internet).

  Further, the contents and order of the steps of the guidance screen display processing flow of the guidance terminal 100 described with reference to FIGS. 4 and 10 are merely examples. For example, in FIG. 10, the guidance terminal 100 may perform the process of S25 before the process of S24. In this case, when the measured value that is the inspection result does not satisfy the “second reference value” (when the inspection result is an extremely abnormal value or the like), the guidance terminal 100 proceeds to the process of S27. On the other hand, the guidance terminal 100 performs the process of S24 when the measurement value as the inspection result satisfies the “second reference value”. Thereafter, the guidance terminal 100 performs the process of S24, proceeds to the process of S28 when the “first standard” is not satisfied, and proceeds to the process of S26 when the “first standard” is satisfied.
