Description

  The present invention relates to a production simulation apparatus and method for creating simulation model data based on operation data obtained from an operation management system from a production automation line and estimating an operation rate and the like of the production automation line.

  In the “production simulation device” of Patent Document 1, the operator aggregates the production result data acquired from the production line management system, and the operator provides the reference data such as the process procedure, the number of devices, the device operation rate, and the working time. The simulation model data is automatically created from the reference data, and the simulation is performed by the simulation execution means.

  In addition, in the “production method evaluation apparatus, production method evaluation method, and storage medium recording the program” in Patent Document 2, when the improvement evaluation of the trouble stop in the production line is evaluated, the improvement items are set as the production efficiency and specific numerical values. The calculation was performed manually and then input to the input / output terminal for simulation.

  However, in the former example of the above prior art, when the operator actually performs simulation, it is necessary for the operator to input simulation parameters such as work time data and operation rate data every time. there were.

  That is, as a means for improving the operation rate of the production line at the production site, for example, there is an improvement in stopping trouble of the apparatus. When evaluating improvement of trouble stop in the production line, to determine which trouble stop of which equipment in the production line is improved, how much the operation rate of the production line is improved, the simulation parameter is set as described above. Since the operator needs to input each time, a lot of work is required. As a result, on-site workers are currently reliant on their own experience and intuition without using a simulation device to improve trouble-stopping.

  Also, in the latter example of the above prior art, when evaluating the improvement of trouble stop in the production line, it is assumed that any trouble stop has been improved, and after manually calculating the working time and production efficiency of the device, Since the calculation result must be input to the simulation device every time and the simulation must be performed, there are the following drawbacks.

  That is, for example, assuming that two trouble stops can be improved, it is almost impossible to determine which trouble stop of which device improves the operation rate of the entire production line most. It was necessary to calculate the work stoppage and the production efficiency of the equipment and perform simulation after manually calculating the trouble stop improvement combination.

  The present invention automatically classifies failure stop phenomena such as trouble stop and automatically performs simulation when each phenomenon is improved, and as a result, the operation rate of the production line when each phenomenon is improved It is an object of the present invention to provide a production simulation apparatus that can quickly identify problems and realize an improvement in productivity of a production line at an early stage.

  In order to achieve the above object, a production line simulation apparatus according to the present invention is a production simulation apparatus that performs an operation simulation of a production line, and an operation data collection unit that collects operation data from an operation management system of the production line; , Model creation means for creating simulation model data of the production line from the operation summary data obtained by the collection means, simulation condition input means for inputting and editing trouble stop improvement conditions as simulation model parameters, and execution of simulation Simulation execution period input means for inputting and editing a period, simulation execution means for performing simulation by inputting simulation model data and simulation condition data, and the simulation execution And wherein the simulation apparatus characterized by having a simulation result display means for displaying the simulation result data obtained by the step to the input-output terminal.

  In the above configuration, the model creating means operates to automatically create model data for performing simulation based on production result data collected from the production line. Therefore, if the operator sets the simulation conditions, the operation simulation result can be referred to by the input / output terminal.

  In the above configuration, the operation data collecting means further classifies trouble phenomena from trouble codes of the operation total data device and stores them in a DB (database) device.

  Therefore, it is possible to classify trouble phenomena from the operation summary data collected from the production line on which the simulation model data is based.

  Further, in the above configuration, the model creation means generates simulation model data for all combinations of failure stop improvement specified by the operator from the failure stop phenomenon of the apparatus obtained by the operation data collection means. It is characterized by creating.

  Therefore, it is possible to create simulation model data of all combinations that can improve the trouble stop phenomenon that is easily improved for the operator.

  In the present invention, an example of trouble stop is mainly described, but there is no problem even if it is intended to improve any failure stop phenomenon.

  In the above configuration, the simulation result display means displays, as a simulation result obtained by the simulation execution means, a list of all patterns set by the model creation means on the input / output terminal in ascending or descending order of availability. It is characterized by.

  Therefore, the simulation results obtained by the simulation execution means can be displayed in a list on the input / output terminals in ascending or descending order of the operation rate, and the production line improvement rate should be improved by the person who improved the production line. It is possible to quickly determine whether or not can be improved most efficiently.

  Furthermore, the simulation condition input means is characterized in that the operator sets the trouble stop phenomenon to be improved and the number of improvement targets to be selected from the input / output terminal.

  Therefore, since the improvement practitioner can specify the failure stop phenomenon to be improved and set the number of improvement targets to be selected from among them, all the combinations of improvements can be simulated. It is possible to perform simulation with a target narrowed down based on the number of improvement targets to be selected.

  According to the present invention, trouble stop phenomena are automatically classified, simulations are automatically performed when each phenomenon is improved, and the operation rate of the production line when each phenomenon is improved can be known in advance. Therefore, problems and countermeasures can be quickly clarified, and productivity of the production line can be improved at an early stage.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing an embodiment of a production line simulation apparatus of the present invention.

  As shown in FIG. 1, the production line simulation apparatus 1 according to the present embodiment includes an operation data collection unit 101, a model creation unit 102, a simulation condition input unit 103, a simulation execution condition period input unit 104, and a simulation execution unit. 105, a simulation result display means 106, an input / output terminal 107, and a DB device 108.

  The operation data collection unit 101 is a unit that collects operation data of the production line 3 collected by the general operation management system 2. The model creation unit 102 obtains simulation model data based on the operation data collected by the operation data collection unit 101 (process order, number of devices, number of inputs, working time, etc.) and the simulation model parameters set by the simulation condition input unit 103. It is a means to create. The simulation condition input means 103 is a means for the operator to set the trouble stop phenomenon to be improved and the number of improvement targets to be selected from the input / output terminal.

  The simulation execution condition period input means 104 is a means for inputting a period during which the simulation is actually executed. The simulation execution means 105 is means for executing the created simulation model. The simulation result display means 106 is means for displaying a list of all the improvement patterns to be improved set by the simulation condition input means on the input / output terminal in ascending or descending order of availability as simulation results obtained by the simulation executing means. is there.

  The production line simulation apparatus according to the present embodiment includes a general information processing apparatus (a storage device such as a CPU, a RAM, or a hard disk drive that executes each process based on a program read from a ROM). That is, the embodiment of the present invention is executed under the control of the CPU based on the software program recorded in the storage medium.

  FIG. 2 is a flowchart for explaining a processing procedure of the production line simulation apparatus according to the present embodiment, and FIG. 3 is a reference screen for displaying a simulation result of the production line simulation apparatus according to the present embodiment. The processing procedure of the production line simulation apparatus according to the present embodiment will be described with reference to FIGS. 1 and 3 as appropriate.

  First, operation data is collected by classifying trouble phenomena from trouble codes of the apparatus (S201). Here, the operation data collection means 301 shown in FIG. 1 collects data necessary for creating a production line simulation model from the operation management system 2 shown in FIG.

  Next, the trouble stop of the improvement target and the number of extractions of the improvement target are collected (S202). The operator inputs the trouble stop phenomenon to be improved and the number of improvement targets to be selected from the phenomenon to be improved from the input / output terminal 107 shown in FIG. The data is collected by the simulation condition input means 103 shown in FIG.

  Here, the trouble stop to be improved refers to a trouble stop that can be improved. Further, the number of extraction targets to be improved is a parameter for determining how many trouble stopping phenomena the content of the improvement pattern of the improvement result 304 shown in FIG. That is, if the trouble stop phenomenon to be improved is not specified, the improvement pattern 304 of the improvement result 304 shown in FIG. 3 includes the trouble stop phenomenon that cannot be improved, which is unnecessary as a simulation result. Things will be displayed.

  Needless to say, the number of trouble stopping phenomena to be improved must be larger than the number of extractions to be improved. Furthermore, if the trouble stop phenomenon to be improved and the number of improvement target extractions are not set, the simulation is performed assuming all combinations that improve the trouble stop phenomenon. In the example shown in FIG. 3, the trouble stop phenomenon to be improved is not specified, and the number of improvements to be extracted is set to 2. The improvement result 304 shown in FIG. 3 displays the result of simulation under the simulation conditions.

  Next, simulation conditions are collected (S203). The operator inputs simulation parameters from the input / output terminal 107 shown in FIG. The data is collected by the simulation execution condition period input means 104 shown in FIG. Here, the simulation execution condition period is an indispensable parameter for performing the simulation, for example, a simulation execution condition period. If the operator does not input simulation parameters, the simulation is performed with default settings.

  Next, simulation is performed with all improvement patterns within the trouble stop phenomenon to be improved and the number of improvement targets extracted (S202). If all the improvement patterns have not been completed, the process proceeds to the next step (S205). If all the improvement patterns have been completed, the process proceeds to the next step (S207).

  Next, simulation model data is created with a new improvement pattern (S205).

  Next, a simulation is executed in accordance with the simulation conditions set in step (S203), and the result is stored in the DB device 108 shown in FIG.

  Finally, after the simulation of all improvement patterns is completed, the contents of each improvement pattern are listed through the screen shown in FIG. 3 at the input / output terminal 7 shown in FIG. indicate. All processing ends here (S207).

  The improvement result 304 shown in FIG. 3 will be described.

  The first column from the left is a column displaying the contents of each improvement pattern, and the second column is a column displaying the operation rate of the production line when the improvement pattern of the first column is executed. The improvement patterns are displayed in ascending order of the operation rate of the production line of each improvement pattern. In the improvement result 304 shown in FIG. 3, the improvement pattern in the first row can achieve the highest operating rate. That is, if the screw tightening error and the container cleaning loss of the production line are improved, the operation rate of the production line is improved to 85%.

  As a result of the above, since the operation rate of the production line when each phenomenon of stoppage and failure is improved is known, the problem can be quickly clarified, and the productivity of the production line can be improved at an early stage.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. For example, the phenomenon to be improved is limited to the trouble stop phenomenon, but any stop and failure phenomenon may be used as long as it can be classified from the trouble code of the apparatus. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
