Description

  The present invention relates to a production management system, for example, a production management system that displays information about an abnormality when an abnormality occurs in a production line or a production facility.

  Conventionally, when a malfunction, abnormality, or stoppage occurs in a production line or production facility, a warning signal sent from the production line or production facility is received and a display device is installed to notify the operation status. There is known an operation management system in which a display device displays a message corresponding to a failure, abnormality or stop with the highest priority when a plurality of defects, abnormalities or stops occur simultaneously in a production facility or the like.

  According to the above-described conventional technology, it is possible to quickly and accurately recover from problems, abnormalities, and stoppages that occur in a production line or a production facility only by dealing with the displayed message (see Patent Document 1 below). reference).

JP 2002-229642 A

  By the way, in the conventional system described in the above-mentioned Patent Document 1, the number of occurrences, occurrence times, malfunctions, abnormalities, stoppages, etc. by receiving alarm signals for each factor transmitted from production lines, production facilities, etc. The recovery time and the time taken from the occurrence to the recovery are measured, but the actual recovery time varies depending on the situation of the place. Therefore, for example, when an operator of a production line or a production facility (an operator other than a recovery operator) waits for recovery of an abnormality, it is simply a warning signal (abnormal type) as described in Patent Document 1 above. By only displaying each past recovery time, the worker cannot accurately grasp when the abnormality is actually recovered, or when the production line or the production facility is restarted. Worker waiting time may be wasted.

  The present invention has been made in view of the above-described problems, eliminates the waste of waiting time for workers of production lines and production facilities, and enables the workers to effectively use the downtime of production lines and production facilities. The purpose is to provide a production management system.

  In order to achieve the above object, the production management system of the present invention is a production management system that displays information relating to an abnormality when an abnormality occurs in a production line or a production facility, and includes a display unit and a restoration worker. A storage unit in which worker information to be identified is stored in association with at least one of a recovery worker level and a workable time of the recovery worker, and when the abnormality occurs, the abnormality is stored in the storage unit. An information processing unit for displaying on the display unit an expected repair time obtained by collating the stored information.

  According to the present invention, the worker information for identifying the restoration worker is stored in the storage unit in association with at least one of the restoration worker level and the workable time of the restoration worker, and the production line or the production facility When an abnormality occurs, the expected repair time obtained by checking the abnormality against the information stored in the storage unit is displayed on the display unit. High-accuracy recovery time according to the situation of the person. For this reason, it is possible to eliminate the waste of waiting time of the workers of the production line and the production equipment, and the worker can effectively use the stop time of the production line and the production equipment.

<Overall configuration of production management system>
FIG. 1 is a block diagram schematically showing the overall configuration of an embodiment of a production management system according to the present invention.

  The production management system 1 of the illustrated embodiment basically includes a management computer 10 and an electric display board 20 as a display unit, and these are the production facilities 5 (the production facilities) installed in the production line. And a portable device 6 owned by a work manager or the like so as to be communicable.

  The management computer 10 receives information (equipment data) relating to the production facility 5 including abnormality data and pre- and post-process buffer data from the production facility 5 installed in the production line, and based on the information, an electric display board A display signal to be transmitted to 20 is generated.

  More specifically, the management computer 10 mainly exchanges information (data) with the production facility 5 and the electric display panel 20, and performs various arithmetic processes, etc., and signals with the external portable device 6. A transmission / reception unit 12 for transmitting / receiving information (data), for example, an interface 13 for a work manager to input data, a database 14 as a storage unit for storing various information such as worker information, The memory 15 is configured to temporarily store various information output from the transmission / reception unit 12, the interface 13, and the database 14 and send the information to the information processing unit 11.

  The information processing unit 11 periodically receives facility data from the production facility 5 and transmits a data request instruction signal to one or both of the transmission / reception unit 12 and the interface 13 as necessary. The transmission / reception unit 12 that has received the data request instruction signal from the information processing unit 11 receives various information such as worker information and repair (recovery, maintenance, etc.) progress information from the portable device 6 for which data has been input by the work manager. Is transmitted to the memory 15 and stored therein. On the other hand, the interface 13 that has received the data request instruction signal from the information processing unit 11 informs the work manager of the input request instruction, and the worker information in which data is input to the interface 13 by the work manager. Various information such as repair progress information is transmitted to the memory 15 and stored therein.

  The information processing unit 11 acquires various information such as various information output from the transmission / reception unit 12 and the interface 13 and worker information output from the database 14 from the memory 15, and performs a predetermined calculation based on the acquired various information. The processing is executed to generate a display signal, and the display signal is transmitted to the electric display panel 20.

  Here, the information (data) stored in the database 14 is associated with, for example, the recovery worker level of each worker (recovery worker) who performs repair (recovery), and the recovery worker level of each recovery worker. Average arrival time (average time from occurrence of abnormality to arrival and start of repair work), average repair time (average time from start of repair work to completion of repair work), average start-up time ( Repair work completion to normal startup confirmation average time), standard recovery worker average arrival time for each abnormality, average repair time, average startup time (for example, average arrival time for each abnormality for each recovery worker, Work time data such as average repair time and time calculated as the average of average startup time), worker information including work available time of each recovery worker, etc. It is included.

  The electric light display board 20 is posted by hanging at a predetermined location such as a production line or a production facility, for example, and the display screen is displayed in accordance with the display signal transmitted from the management computer 10 (information processing unit 11 thereof). The display content is changed, and various information is displayed (notified) to each worker.

  It should be noted that the specific configuration of the management computer 10 is not limited to the illustrated example. For example, the database 14 and the memory 15 may be separate as shown in the figure, or may be integrated. For example, the database 14 may be provided outside the management computer 10.

<Production management method using production management system>
Hereinafter, a production management method by the production management system 1 shown in FIG. 1, particularly a production management method by the management computer 10 of the production management system 1 when an abnormality occurs in the production line or production facility, will be described with reference to FIGS. Will be described in detail with reference to FIG.

  When an abnormality occurs in a production line or a production facility, as shown in FIG. 2, first, the information processing unit 11 of the management computer 10 starts from the production facility 5 with abnormal data (data relating to an abnormality in the production facility 5) and pre- and post-processes. Receives buffer data (data indicating the connection between the process where the production facility 5 is placed and the process before and after the process), and stores the abnormal data and the buffer data before and after the process in each folder set inside. (S11). By referring to (comparing) the abnormal data and the pre- and post-process buffer data, it is possible to determine a limit at which the abnormality occurring in the production facility 5 affects the pre- and post-process.

  Next, the information processing unit 11 acquires data including the above-described worker information and the like from the mobile device 6 and the like that are communicably connected to the database 14, the interface 13, and the transmission / reception unit 12 via the memory 15 ( S12).

  Next, the information processing unit 11 associates and collates the abnormal data received from the production facility 5 in S11 and the data acquired in S12, and from these data, an operator (recovery worker) who deals with the abnormality is identified. In addition to specifying (assigning), the specified recovery operator calculates an expected repair time required for repairing (recovering) the abnormality (S13). Note that the identification (assignment) of the recovery worker here may be performed automatically by the information processing unit 11 or manually by a work manager or the like from data stored in the database 14 or the like. good.

  Next, the information processing section 11 generates a display signal for displaying the estimated repair time calculated in S13 and transmits it to the electric display board 20 (S14).

  Here, the electronic display panel 20 that has received the display signal from the information processing unit 11 displays, for example, the screen shown in FIG.

  Specifically, in the electric display panel 20, as shown in FIG. 3, it is generated at the production facility 5 of the restoration worker specified in S13 on the upper side of the column indicating the own process where the production facility 5 is installed. The expected repair time (average arrival time + average repair time + average start-up time) for the detected abnormality is displayed (for example, each time is displayed in different colors). In addition, in order to display the time actually required (with the subsequent passage of time), the same time as the upper side is displayed on the lower side. However, in order to distinguish between the upper side and the lower side, it is desirable to change the display color (for example, change the shade of the display color between the upper side and the lower side) first. Furthermore, from the abnormality data acquired in S11 and the pre- and post-process buffer data, the limit time that the abnormality occurring in the production facility 5 affects the subsequent process and the limit time that affects the previous process are displayed together.

  At this stage, if the restoration worker corresponding to the abnormality occurring in the production facility 5 cannot be specified, the expected repair time for the abnormality of the standard restoration worker is displayed on the electric display panel 20. Also good.

  Next, as shown in FIG. 2, the information processing section 11 determines whether it is an update timing (for example, whether a predetermined time has elapsed) or whether repair progress information has been input from the mobile device 6 or the like (S15). When it is an update timing or when it is determined that repair progress information has been input, the expected repair time calculated in S13 is updated, and a display signal corresponding to the updated expected repair time is generated. It transmits to the light-emitting display board 20 (S16).

  Here, the electric display panel 20 that has received the updated display signal from the information processing unit 11 displays, for example, the screens shown in FIGS. 4 to 6.

  Specifically, as shown in FIG. 4, the display on the electronic display panel 20 does not change the display on the upper side of the column indicating the own process, and updates the display on the lower side with the passage of time (for example, the location of the average arrival time). When the recovery worker actually arrives at the production facility 5 (in other words, when the repair progress information on the arrival of the recovery worker has been input from the portable device 6 or the like) The estimated repair time after update reflecting the actual arrival time (actual arrival time) (actual arrival time + average repair time + average start-up time) is displayed. In the example shown in FIG. 4, since the arrival (actual arrival time) of the recovery worker at the production facility 5 is delayed from the expected (average arrival time), the average repair time and average startup time on the lower side are increased accordingly. The average repair time and the average start-up time will be deviated (become delayed) and the expected repair time will exceed the limit time that affects the post-process. The expected associated equipment downtime is also displayed.

  Moreover, in the electric light display board 20, about the display of the lower side of the column which shows an own process, when the restoration | repair worker who arrived at the production facility 5 is repairing, as shown in FIG. 5, it updates with progress of time (for example, When the repair worker completes the repair work for the production facility 5 (in other words, the repair progress information of repair completion is input from the mobile device 6 etc.) As shown in FIG. 6, the actual time after update (actual arrival time + actual repair time +) reflecting the actual repair time (actual repair time) and the actual start-up time (actual start-up time), as shown in FIG. (Actual startup time) is displayed (for example, each time is displayed in the same color as the upper side). In the example shown in FIG. 6, the repair work (actual repair time) of the production facility 5 by the restoration worker is as expected (average repair time), so the subsequent process stops for the same time as the predicted related equipment stop time described above. However, the previous process is not affected (that is, the previous process is not stopped).

  When the repair work of the production facility 5 by the restoration worker is completed and normal operation is resumed, the display on the lower side of the column indicating the own process on the electronic display panel 20 is updated sequentially as time passes. Will be.

  At this stage, since the actual arrival time, actual repair time, and actual start-up time for the specified recovery worker with respect to the abnormality are obtained, the information processing unit 11 saves them in the database 14 using those data. The updated worker information (average arrival time, average repair time, average start-up time) can be updated.

  As shown in FIG. 2, the information processing unit 11 periodically determines whether or not the repair has been completed (S17). When it is determined that the repair has been completed, the above-described series of processing ends. To do.

  As described above, in the production management system 1 of the present embodiment, the worker information that identifies the restoration worker is linked to at least one of the restoration worker level and the workable time of the restoration worker, and the database as a storage unit 14, when an abnormality occurs in the production line or the production facility, the expected repair time obtained by checking the abnormality against the information stored in the database 14 is displayed on the electric display panel 20 as a display unit. Therefore, it is possible to present a highly accurate recovery time according to the situation of the worker on the spot to the worker of the production line or the production facility. For this reason, it is possible to eliminate the waste of waiting time of the workers of the production line and the production equipment, and the worker can effectively use the stop time of the production line and the production equipment.

  Further, in the production management system 1 of the present embodiment, even a recovery operator who actually deals with an abnormality in the production line or the production facility can check the arrival time, the repair time, and the like from the display content of the electric display panel 20. There is also an advantage that it leads to proper repair work.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
