Summary of the Invention

Problems to be Solved by the Invention

[0006] In mass production of molded products using molds, for example, there are the following problems.

[0007] First, although the molding conditions during mass production are generally set to standard molding conditions, in practice, they are left to the discretion of the on-site workers and are changed according to the situation of trial molding at the start of work. Therefore, there are differences in the skills of the workers, resulting in variations in quality.

[0008] Second, the molding conditions changed on-site are not grasped by the management side. The site is operated in a situation where the standard molding conditions are not observed, and it is impossible to trace the cause of molding defects without change records. Not only the quality but also the molding cycle fluctuates, resulting in variations in manufacturing costs.

[0009] Third, in a situation where the molding conditions are left to the discretion of the on-site workers, it is impossible to provide the on-site workers with the optimal molding conditions.

[0010] Fourth, even for the molding conditions set by the worker, the operation of the molding machine body does not necessarily operate as set. Therefore, for optimal molding condition support, it is necessary to compare the worker's set value with the actual operation data of the molding machine, and it is necessary to adjust the difference in the molding conditions.

[0011] In view of the above circumstances, an object of the present invention is to obtain good production results regardless of individual differences among workers.

Means for Solving the Problems

[0012] A production monitoring device according to one aspect of the present invention collects the set value from a controller that controls a production machine based on the set value determined by a worker with reference to a standard value, collects the actual value from a sensor that detects the actual value of the production machine that operates under the control based on the set value, collects the worker ID from a worker terminal that acquires a worker ID for identifying the worker who determined the set value a collection unit, Based on the date and time for specifying the set value, the date and time for specifying the actual value, and the date and time for specifying the operator ID, a specifying unit that specifies the set value determined by the operator identified by the operator ID and the actual value based on the set value; comprises.

[0013] Thereby, administrators or operators can identify which operator set what set value and how much the actual value differs from the set value when this set value was set.

[0014] The collection unit further collects the production results of the production machine, The specifying unit may further specify the production results of the production machine that operates under control based on the set value determined by the operator identified by the operator ID, based on the date and time for specifying the production results.

[0015] Thereby, administrators or operators can identify which operator set what set value, how much the actual value differs from the set value in this case, and what production results were obtained in this case.

[0016] The production results may include cycle time and / or defect rate.

[0017] Thereby, when problems such as molding defects, molding cycle variations, and variations in manufacturing costs occur, it becomes possible to trace the causes.

[0018] The production monitoring device compares the set values, the actual values, and the production results determined by a plurality of different operators identified by a plurality of different operator IDs, and determines the set value, the actual value, and the operator who determined the set value when the best production results are obtained. A comparative analysis unit may further be provided.

[0019] As a result, administrators or operators can identify which operator obtained the best production results when setting which set values. This makes it possible to identify operators who were unable to obtain good production results and provide guidance and support to those operators.

[0020] The production monitoring device compares the actual value and the standard value when the best production result is obtained, and if it is determined that the difference between the actual value and the standard value is equal to or greater than a threshold value, a reset unit that resets a new standard value so that the difference from the actual value is less than the threshold value may be further provided.

[0021] As a result, in the future, the operator can determine the set value based on the new standard value reset based on the best production result, and can suppress variations in quality regardless of the individual differences (skill differences, proficiency) of the operator and obtain good production results.

[0022] The reset unit may reset a plurality of different new standard values according to time and / or weather conditions.

[0023] As a result, the operator can set the optimal set value without being aware of the time and / or weather conditions, and can suppress variations in quality regardless of the individual differences (skill differences, proficiency) of the operator and obtain good production results.

[0024] The production machine includes a main body and parts that are detachable from the main body. The parts are any of a plurality of individuals that are detachable from the main body. The plurality of individuals are each identified by an individual ID. The collection unit further collects an individual ID that identifies the individual mounted on the main body. Based on the date and time for identifying the individual ID, the date and time for identifying the set value, and the date and time for identifying the actual value, the specific unit identifies the set value when the individual identified by the individual ID is mounted and the actual value based on the set value. The re-setting unit re-sets a plurality of different new standard values for each individual identified by the individual ID. This may be done.

[0025] Parts wear out due to aging, such as wear according to the usage status of each individual, and the condition varies for each individual. Also, the condition such as the wear state of each individual is not usually measured. Therefore, if different standard values are set for each individual part, the operator can set the optimal setting value without being aware of the individual differences of the parts, and can suppress the variation in quality regardless of the individual differences (skill differences, proficiency) of the operator, aiming to obtain good production results.

[0026] Each individual has an individual ID code that is optically readable and associated with the individual ID. The operator terminal optically reads the individual ID code, obtains the individual ID associated with the individual ID code, and supplies the individual ID to the production monitoring device. The collection unit may collect the individual ID code acquired by the operator terminal.

[0027] Thereby, the collection unit of the production monitoring device can acquire the individual ID from the operator terminal, associate the date and time for specifying the individual ID, and store the individual ID in time series.

[0028] The operator has an operator ID code that is optically readable and associated with the operator ID. The operator terminal optically reads the operator ID code, obtains the operator ID associated with the operator ID code, and supplies the operator ID to the production monitoring device. The collection unit may collect the operator ID code acquired by the operator terminal.

[0029] Thereby, the collection unit of the production monitoring device can collect the operator ID from the operator terminal, associate the date and time for specifying the operator ID, and store the operator ID in time series.

[0030] A production monitoring program according to an aspect of the present invention causes a computer of a production monitoring device to collect the set value from a controller that controls a production machine based on the set value determined by an operator with reference to a standard value, collect the actual value from a sensor that detects the actual value of the production machine that operates under control based on the set value, collect the operator ID from an operator terminal that acquires an operator ID for identifying the operator who determined the set value, a collection unit, a specifying unit that specifies the set value determined by the operator identified by the operator ID and the actual value based on the set value, based on the date and time for specifying the set value, the date and time for specifying the actual value, and the date and time for specifying the operator ID to operate.

Embodiments for Carrying Out the Invention

[0036] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0037] 1. Overview of the Production Monitoring System

[0038] Fig. 1 schematically shows a production monitoring system according to an embodiment of the present invention.

[0039] The production monitoring system 1 includes a plurality of sensors 13 provided in the production machine 10, a controller 20, an operator terminal 30, and a production monitoring device 40. The operator terminal 30 is wirelessly communicably connected to the controller 20 and the production monitoring device 40. The controller 20 and the production monitoring device 40 are wirelessly communicably connected. The controller 20 and the production machine 10 are wired or wirelessly communicably connected. The plurality of sensors 13 and the production monitoring device 40 are wired or wirelessly communicably connected.

[0040] The production machine 10 is a machine installed in a factory or the like for continuously producing products, for example, an injection molding machine. Hereinafter, the case where the production machine 10 is an injection molding machine will be mainly described. The production machine 10 includes a main body 11 and a component 12 that is detachable from the main body 11.

[0041] The main body 11 includes facilities such as a molding machine, a temperature controller, and a dryer. The molding machine includes parts such as a hopper, an injection mechanism, and a mold clamping mechanism. The temperature controller includes a heating cylinder, a heater, and the like.

[0042] The component 12 is, for example, a mold. The component 12 is any one of a plurality of individuals that are detachable from the main body 11. In other words, there are a plurality of different individuals of the same type of mold as the component 12, and any one of the individuals is attached to the main body 11 as the component 12. The plurality of individuals as the component 12 are each identified by an individual ID. Specifically, each individual as the component 12 has an optically readable individual ID code 14. Specifically, a physical nameplate is attached to the component 12, and the optically readable individual ID code 14 is described on the nameplate. The individual ID code 14 is, for example, a QR (registered trademark) code or a barcode. The individual ID (serial number, etc.) is associated with the individual ID code 14.

[0043] The production machine 10 is provided with a plurality of sensors 13. The plurality of sensors 13 may be built-in or retrofitted. The plurality of sensors 13 detect the actual values of various management items for various parts and components 12 of the main body 11 of the production machine 10. The various management items are, for example, pre-drying temperature and time, cylinder temperatures of various parts such as the rear part, middle part, and front part, nozzle temperature, injection pressure, injection speed, screw rotation speed, and mold temperature, etc. Each sensor 13 supplies the detected actual value to the production monitoring device 40, either via or without going through the controller 20 and / or a PLC (Programmable Logic Controller) (not shown). Note that the "actual value" means a value actually detected by the sensor 13 when the production machine 10 is controlled and operated based on the "set value", which is different from the "set value" set in the production machine 10 from the controller 20.

[0044] The operator of the production machine 10 wears a physical nameplate 50, an ID card, etc., and the operator ID code 51 that can be optically read is described on the nameplate 50, etc. The operator ID code 51 is, for example, a QR (registered trademark) code or a barcode, etc. The operator ID (serial number, etc.) is associated with the operator ID code 51.

[0045] The operator terminal 30 is used by the operator of the production machine 10. The operator terminal 30 is a device having a display device and an input device (e.g., a touch panel), and an optical reading device (e.g., a camera), and is, for example, a tablet computer or a smartphone, etc. The operator terminal 30 supplies the set value to be set in the production machine 10, which is input by the operator, to the controller 20.

[0046] The controller 20 is a dedicated computer for controlling the production machine 10. The controller 20 acquires the set values for the various management items of the various parts and components 12 of the main body 11 of the production machine 10 from the operator terminal 30 and sets them in the production machine 10. The controller 20 supplies the set value to the production monitoring device 40, either via or without going through a PLC (not shown).

[0047] The production monitoring device 40 is a personal computer or a dedicated computer. The production monitoring device 40 collects set values for various parts of the main body 11 of the production machine 10 and various management items of the parts 12 from the controller 20, collects actual values from a plurality of sensors 13, and performs information processing.

[0048] 2. Functional configuration of the production monitoring system

[0049] Figure 2 shows the functional configuration of the production monitoring system.

[0050] In the computer of the operator terminal 30, the CPU operates as an operator ID acquisition unit 301, an individual ID acquisition unit 302, and a set value input unit 303 by loading the program recorded in the ROM into the RAM and executing it.

[0051] In the computer of the controller 20, the CPU operates as a set value control unit 201 and a production result acquisition unit 202 by loading the program recorded in the ROM into the RAM and executing it.

[0052] In the computer of the production monitoring device 40, the CPU operates as a collection unit 401, a specification unit 402, a comparison and analysis unit 403, and a reset unit 404 by loading the program recorded in the ROM into the RAM and executing it. The production monitoring device 40 has a DB410 set in a large-capacity non-volatile storage device such as an HDD or an SSD.

[0053] 3. Operation flow of the production monitoring device

[0054] Figure 3 shows the operation flow of the production monitoring device.

[0055] At the start of work, the worker causes the optical reader 311 (camera) of the worker terminal 30 to read the worker ID code 51 described on his / her nameplate 50. The worker ID acquisition unit 301 of the worker terminal 30 acquires, via the network, the worker ID that identifies each worker and is associated with the optically read worker ID code 51. The worker terminal 30 supplies the worker ID to the production monitoring device 40.

[0056] The collection unit 401 of the production monitoring device 40 collects the worker ID 411 from the worker terminal 30, and stores the worker ID 411 in the DB 410 (database) in chronological order, associating the date and time for identifying the worker ID 411 (step S101). The date and time for identifying the worker ID 411 may be, for example, the date and time when the worker terminal 30 acquired the worker ID 411 or the date and time when the production monitoring device 40 collected the worker ID 411.

[0057] Furthermore, the worker causes the optical reader 311 (camera) of the worker terminal 30 to read the individual ID code 14 provided on the nameplate of the individual, which is the component 12 mounted on the main body 11 of the production machine 10. The individual ID acquisition unit 302 of the worker terminal 30 acquires, via the network, the individual ID that identifies each individual and is associated with the optically read individual ID code 14. The worker terminal 30 supplies the individual ID to the production monitoring device 40.

[0058] The collection unit 401 of the production monitoring device 40 collects the individual ID 412 from the worker terminal 30, and stores the individual ID 412 in the DB 410 in chronological order, associating the date and time for identifying the individual ID 412 (step S102). The date and time for identifying the individual ID 412 may be, for example, the date and time when the worker terminal 30 acquired the individual ID 412 or the date and time when the production monitoring device 40 collected the individual ID 412.

[0059] Subsequently, the operator operates the production machine 10 on a trial basis and determines set values according to the equipment status of the mold, material, molding machine, temperature controller, dryer, etc. on the day and conditions such as environmental temperature, time, and / or weather conditions, based on predetermined standard values for various parts of the main body 11 of the production machine 10 and various management items of the parts 12. The operator inputs the determined set values into the set value input section 303 of the operator terminal 30. The set value input section 303 of the operator terminal 30 supplies the set values to the controller 20. As described above, the various management items are, for example, pre-drying temperature and time, cylinder temperatures at various parts such as the rear, middle, and front, nozzle temperature, injection pressure, injection speed, screw rotation speed, and mold temperature.

[0060] The set value control section 201 of the controller 20 acquires the set values determined by the operator based on the standard values from the operator terminal 30 and controls the production machine 10 based on the set values. The controller 20 supplies the set values for various management items of various parts of the main body 11 of the production machine 10 and the parts 12 to the production monitoring device 40, either via a PLC (not shown) or without it. The controller 20 supplies the latest set values to the production monitoring device 40 each time the set values are changed.

[0061] The collection section 401 of the production monitoring device 40 collects the set values 413 for various management items of various parts of the main body 11 of the production machine 10 and the parts 12 from the controller 20, associates the date and time identifying the set values 413, and stores the set values 413 in the DB 410 in chronological order (step S103). The date and time identifying the set values 413 may be, for example, the date and time when the controller 20 sets or supplies the set values 413 or the date and time when the production monitoring device 40 collects the set values 413.

[0062] The production machine 10 is controlled to operate based on the set values for various management items of various parts of the main body 11 and the parts 12 set by the controller 20.

[0063] The plurality of sensors 13 periodically detect the actual values of various management items for various parts and components 12 of the main body 11 of the production machine 10. The plurality of sensors 13 supply the actual values of various management items for various parts and components 12 of the main body 11 of the production machine 10 to the production monitoring device 40, either via the controller 20 and / or a PLC (not shown) or without passing through them.

[0064] The collection unit 401 of the production monitoring device 40 periodically collects the actual values 414 of various management items for various parts and components 12 of the main body 11 of the production machine 10 from the plurality of sensors 13, associates the date and time for specifying the actual values 414, and stores the actual values 414 in the DB 410 in chronological order (step S104). The date and time for specifying the actual values 414 may be, for example, the date and time when the plurality of sensors 13 detected or supplied the actual values 414 or the date and time when the production monitoring device 40 collected the actual values 414.

[0065] The collection unit 401 of the production monitoring device 40 further collects the production result 415 of the production machine 10, associates the date and time for specifying the production result 415, and stores the production result 415 in the DB 410 in chronological order (step S105). The production result 415 includes the cycle time and / or the defect rate. The collection unit 401 may obtain the production result 415 of the production machine 10, for example, from the production result acquisition unit 202 of the controller 20, or may obtain it by being input by an administrator or an operator in a position to manage the operator. The date and time for specifying the production result 415 is the date and time when the production machine 10 generated the production result 415. In other words, the date and time for specifying the production result 415 is not, for example, the date and time when the administrator or the operator etc. input the production result 415 to the production monitoring device 40 after the production machine 10 has finished operating, but the date and time during operation when the production machine 10 generated the production result 415.

[0066] The specifying unit 402 of the production monitoring device 40 specifies the set value 413 determined by the operator identified by the operator ID 411 and the actual value 414 based on the set value 413 when the individual identified by the individual ID 412 is worn, based on the date and time for specifying the operator ID 411, the date and time for specifying the individual ID 412, the date and time for specifying the set value 413, and the date and time for specifying the actual value 414. The specifying unit 402 further specifies the production result 415 of the production machine that operates under control based on the set value 413 determined by the operator identified by the operator ID 411, based on the date and time for specifying the production result 415 (step S106). The specifying unit 402 may output the set value 413 determined by the operator, the actual value 414 based on the set value 413, and the production result 415 to a display 421 that can be browsed by, for example, an administrator or an operator. Thereby, the administrator or the operator can identify which operator set what set value 413 when using which individual as the component 12, how much the actual value 414 differs from the set value 413 when this set value 413 was set, and what production result 415 was obtained in this case.

[0067] The comparison and analysis unit 403 compares the set values 413, actual values 414, and production results 415 determined by a plurality of different operators identified by a plurality of different operator IDs 411 for each individual of the component 12, and determines the set value 413, the actual value 414, and the operator who determined the set value 413 when the best production result 415 was obtained (step S107). The comparison and analysis unit 403 may output the set value 413, the actual value 414, and the operator who determined the set value 413 when the best production result 415 was obtained to a display 421 that can be browsed by, for example, an administrator or an operator. Thereby, the administrator or the operator can identify which operator obtained the best production result 415 when setting what set value 413 when using which individual as the component 12, conversely, whether an unfavorable production result 415 was obtained, and furthermore, the individual differences in the production results 415. Thereby, it becomes possible to identify an operator who could not obtain a good production result and to guide and support that operator.

[0068] When the re - setting unit 404 compares the actual value 414 with the standard value when the best production result 415 is obtained when a specific individual is mounted as the component 12, and determines that the difference between the actual value 414 and the standard value is equal to or greater than the threshold value, it re - sets a new standard value so that the difference from the actual value 414 is less than the threshold value (step S108). The "standard value" is a numerical range in which it is assumed that the production machine 10 operates without problems and there are no problems with the quality of the products produced. The re - setting unit 404 supplies the re - set new standard value to the controller 20 and the operator terminal 30. As a result, in the future, the operator can determine the set value based on the new standard value re - set based on the best production result 415, and can suppress the quality variation regardless of the individual differences (skill differences, proficiency) of the operator and obtain good production results.

[0069] For example, the existing standard value is 165°C (±10°C). The operator sets 170°C, which falls within that range, as the set value based on the existing standard value. When the production machine 10 is controlled and operates based on the set value of 170°C, the sensor 13 detects 175°C as the actual value. Assuming that the production result 415 in this case is the best. The re - setting unit 404 determines that the difference between the actual value 175°C and the standard value 165°C is equal to or greater than the threshold value of ±10°C. The re - setting unit 404 re - sets a new standard value so that the difference from the actual value 175°C is less than the threshold value of ±10°C. For example, the re - setting unit 404 may re - set the new standard value to 170°C based on the set value of 170°C when the best production result 415 is obtained.

[0070] Also, the re - setting unit 404 re - sets a plurality of different new standard values for each individual identified by the individual ID 412. The mold, which is the component 12, undergoes aging deterioration such as wear according to the usage status of each individual, and the condition is different for each individual. Also, the condition such as the wear state of each individual is not usually measured. Therefore, if different standard values are set for each individual of the component 12, the operator can set the optimal set value without being aware of the individual differences of the component 12, and can suppress the quality variation regardless of the individual differences (skill differences, proficiency) of the operator and obtain good production results.

[0071] Further, the reset unit 404 may reset a plurality of different new standard values for one part of the main body 11 or one unit of the component 12 according to the time (e.g., seasons such as spring, summer, autumn, and winter) and / or weather conditions (e.g., temperature, humidity, air pressure, etc.). By setting different standard values according to the time and / or weather conditions, the operator can set the optimal set value without being aware of the time and / or weather conditions, and it is possible to suppress the variation in quality regardless of the individual differences (skill differences, proficiency) of the operator and obtain good production results.

[0072] 4. Conclusion

[0073] According to the present embodiment, in a situation where it is necessary for an operator to determine a set value on-site, it is possible to provide the operator with a standard value for determining the optimal set value. Therefore, it is possible to suppress the variation in quality regardless of the individual differences (skill differences, proficiency) of the operator, the individual differences of the component 12, the time, and / or the weather conditions, and obtain good production results.

[0074] Also, the actual value of the production apparatus 10 may not match the set value. By comparing the set value and the actual value, it is possible to reset a new standard value to assist the operator in determining the optimal set value based on the difference.

[0075] In addition, each time the set value 413 is changed, the production monitoring device 40 can store the latest set value 413 in time series in combination with the operator ID 411. Therefore, by recording that the operator has changed the set value on-site during the production operation, the administrator can grasp the act. For example, when a set value deviating from the threshold range of the standard value is set in the controller 20, the controller 20 may output an alert by light emission or voice. Thereby, it is possible to suppress the occurrence of artificial troubles in which the production machine 10 operates with a set value deviating from the threshold range of the standard value. Since there is a change record, it is possible to trace the cause when problems such as molding defects, molding cycle variations, and variations in manufacturing costs occur.

[0076] Although each embodiment and each modification of the present technology have been described above, the present technology is not limited only to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present technology.
