The operation means, for example, that at least a part of the bottom seal portion 100 to the top seal portion 500 is operating for manufacturing a product.

・ "Setting value"
“Set value” is a set value of the operation in the filling and sealing machine 10. In one example, the setting values input to the PLC 10 </ b> A described with reference to FIGS. 5, 6, 9, 11, and 12 are stored in the storage device in the data server 30. The setting value may be transmitted to the data server 30 (via the information collection terminal 12) by the PLC 10A.

・ "Operation time or number of operations of each element in the filling and sealing machine"
The "operating time or number of operations of each element in the filling and sealing machine" represents the operating time (use time) of each element in the filling and sealing machine 10, and in one example, FIG. 5, FIG. 6, FIG. 9, FIG. The operation time or the number of operations of the elements provided in each of the bottom seal portion 100 to the top seal portion 500 described with reference to FIG. In one example, uptime represents the time each element was used to manufacture a product.

  In the filling and sealing machine 10, each element is independently replaceable. Therefore, each element may have a different operating time. For example, when the filling and sealing machine 10 is operated for 10 hours after the ultrasonic oscillator 204 is replaced at the time when the operation time of the entire filling and sealing machine 10 is 50 hours, the operation time of the ultrasonic oscillator 204 is 10 hours. The operation time of the other elements is 60 hours (50 hours + 10 hours).

  The operation time may be transmitted to the data server 30 by the PLC 10A (via the information collection terminal 12), or may be directly input to the data server 30 by an administrator of the filling and sealing machine 10.

・ "Abnormal / alarm information"
“Abnormality / alarm information” indicates an abnormality and an alarm event that have occurred in the filling and sealing machine 10. Each event includes the content and date and time of occurrence of “abnormal” or “alarm”. “Abnormal” means that an abnormal state has occurred in the filling machine. “Alarm” means that an alarm condition has occurred in the filling and sealing machine 10.

  The occurrence of a defect in the completed carton 5 may be detected by an operator who handles the filling and sealing machine 10, or may be detected by a device such as the PLC 10A or the management PC 40 based on detection results of various sensors. , May be detected by an inspection device installed inside or outside the filling machine.

  The abnormal state of the filling and sealing machine 10 may be detected by an operator, or may be detected by the PLC 10A or the management PC 40. In one example, when the operator discovers that an abnormality has occurred in the filling and sealing machine 10, the operator operates the emergency button of the filling and sealing machine 10. When detecting that the emergency button has been operated, the PLC 10A notifies the data server 30 of the occurrence of the abnormal state. Upon receiving the notification, the data server 30 stores information corresponding to the notification in a storage device in the data server 30.

  The management PC 40 may detect the occurrence of an abnormal state, for example, based on a measurement value regarding the filling and sealing machine 10. When detecting the occurrence of an abnormal state, the CPU 41 of the management PC 40 stores information on the abnormal state in the data server 30. Thereby, the information is stored in the storage device in the data server 30.

・ "Measured value"
“Measurement value” indicates a measurement value of an element constituting the filling and sealing machine 10. In one example, the measurement values as described with reference to FIGS. 5, 6, 9, 11, and 12 are input to the PLC 10A and stored in a storage device in the data server 30. . The measurement value further includes “product ID”, “carton cell frame No.”, and “product judgment”. Each measurement value may be transmitted to the data server 30 by the PLC 10A (via the information collecting terminal 12), or may be directly input to the data server 30 by an administrator of the filling and sealing machine 10.

The “product ID” is assigned to each product manufactured in the filling and sealing machine 10.
The “mandrel No.” and “carton cell frame No.” identify the mandrel and the carton cell frame that conveyed each carton 5 in the filling and sealing machine 10. In the filling and sealing machine 10, each mandrel conveys each carton in a path including the bottom seal section 100, and the carton cell frame conveys a path including each section in the top seal section 500.

  Each of "product determination (automatic)" and "product determination (visual)" indicates a determination result as to whether or not a defect has occurred in the product (or the carton 5 before the product is manufactured). If a failure has occurred, the determination result is “NG”, and if no failure has occurred, the determination result is “OK”. “Product determination (automatic)” is a determination result by the PLC 10A, the PC or PLC for edge computing, or the management PC 40 using measured values and the like. “Product determination (visual)” is a result of visual determination by an operator. The determination includes, for example, whether or not the welding position of the plug 4 in the carton 5 is within a given range (OK if within the given range, NG if outside the given range). In addition, the determination may be based on the welding state of the plug 4. The determination may be based on the results of a permeate check (leakage test) or a destruction check by a sampling inspection.

・ "Judgment criteria"
The “criterion” includes a criterion such as a warning in the filling and sealing machine 10.

  More specifically, the “judgment criterion” includes a threshold value for the operation time (use time) of each component in the filling and sealing machine 10 and a reference range for a measurement value representing the state of each element. The threshold value for the operating time is a replacement warning value for issuing a warning about replacement of each element (part), and a value lower than the replacement warning value, and a ratio display threshold value used in displaying the operating time (see FIG. 16 described later). See).

  The reference range for the measured value defines, for example, a range used for “product determination”. In one example, if the measured value of the given carton during processing is within the reference range, the result of “product determination” for the carton is “OK”, and if the measured value is outside the reference range, the carton is Is "NG" as a result of "product determination".

[Data Management Screen]
FIG. 14 is an example of a data management screen displayed on the monitor 48 of the management PC 40.

  The management PC 40 provides information on the filling and sealing machine 10 using various data described with reference to FIG. Screen 1100 (data management screen) in FIG. 14 receives selection of the type of information to be provided. Screen 1100 includes a table 1101. “Data reference name” in the table 1101 indicates the type of information to be provided.

  The table 1101 includes various items in addition to the “data reference name”. For example, “maintenance inspection status” represents information on maintenance inspection for each element (part) in the filling and sealing machine 10. “PN-0001_2017 year_daily total data” represents information on the operation status of each day in 2017 for the filling and sealing machine 10 specified by the model name “PN-0001”. “PN-0001_2016_total data” indicates information on the operating status in 2016 of the filling and sealing machine 10 specified by the model name “PN-0001”.

  The table 1101 further includes items “edit”, “data reference creation”, “update date”, “creator”, and “export”. “Edit” displays an icon operated to edit provided information. "Create data reference" displays an icon operated to refer to the provided information. "Export" displays an icon operated to change the data of the provided information into a given format.

  When an icon for editing or referencing information is operated, the CPU 41 reads out information of a period and a type corresponding to the icon from the data server 30 and displays the information on the monitor 48. In one example, the icons are operated via mouse 42 and / or keyboard 43. In this sense, the mouse 42 and / or the keyboard 43 constitute an input interface for receiving designation of a given period when data of a given period is displayed. When the management PC 40 includes a touch panel, an input interface may be configured by a touch sensor included in the touch panel.

  Each of the "update date" and "creator" indicates the date on which the data on the provided information was updated and the person who updated the data.

  In one example, the CPU 41 may request the user to log in to display the screen 1101. The CPU 41 may adjust the type of information displayed on the table 1101 according to the type of the logged-in user. That is, the management PC 40 may change the type of information permitted to be viewed depending on which user is logged in. In one example, the management PC 40 allows the user A to browse all information in the table 1101. User B is permitted to view total data such as “PN-0001_2017_daily total data”, but is prohibited from viewing “maintenance inspection status”. In this case, display of prohibited information on screen 1101 may be omitted.

[Equipment operation monitor]
FIG. 15 is a diagram illustrating an example of a screen displayed when the “data reference creation” icon is operated for “PN-0001_2017_daily total data” in FIG. 14. The screen 1200 in FIG. 15 is a facility operation monitor displayed on the monitor 48 and displaying the overall operation status of the filling and sealing machine 10. The operation of the icon is an example of designation of a period of data to be displayed.

  The screen 1200 is an example of a display screen of operation data during a period (2017) specified by an icon operation. The screen 1200 includes a region 1201 relating to a period during which power is supplied to the filling and sealing machine 10, a region 1202 relating to a period during which the filling and sealing machine 10 is operated, and a region 1203 relating to an alarm.

  The area 1201 includes a graph and a date (Nov. 16, 2017, November 16, 2017). This graph shows the change over time of the power-on ratio. When a date is selected, the CPU 41 reads out information on the operating status for the selected day from the data server 30, creates a graph based on the information, and displays the graph in the area 1201. The graph represents the ratio of the time during which the power is supplied to the filling and sealing machine 10 for every predetermined length of time (for example, 30 minutes or 1 hour). The selection of the date is another example of specifying the period of the data to be displayed.

  When an event of “abnormality / alarm information” is stored at a time corresponding to the graph, the CPU 41 may display the event on the graph. Icons A11 and A12 and lines L11 and L12 are displayed in the graph of the area 1201. These displays are performed, for example, in a period corresponding to the time from line L11 to line L12, when an event (abnormality) described in icon A11 occurs at a frequency equal to or higher than a given frequency, and corresponds to the time corresponding to line L12. Means that a warning (icon A12) has been output. An abnormality is, for example, a defective carton.

  The area 1202 includes a graph and a date (2017/11/16 (November 16, 2017)). This graph shows the change over time of the operating ratio. When a day is selected, the CPU 41 reads information on the operating status for the selected day from the data server 30, creates a graph based on the information, and displays the graph in the area 1202. The graph calculates the ratio of the time during which the filling and sealing machine 10 is operated for each predetermined length of time (for example, 30 minutes or 1 hour).

  When an event of “abnormality / alarm information” is stored at a time corresponding to the graph, the CPU 41 may display the event on the graph. Icons A21 and A22 and lines L21 and L22 are displayed in the graph of the area 1202. These displays indicate, for example, that the event (abnormality) described in the icon A21 has occurred at a frequency equal to or higher than a predetermined frequency in a period corresponding to the time from the line L21 to the line L22, and Means that a warning (icon A22) was output at the time of the execution. An example of the abnormality is an abnormal state of the filling and sealing machine 10.

  An area 1203 stores a list of events (abnormality / alarm generation status) registered as “abnormality / alarm information” stored in association with the period (2017) specified by the icon operated in FIG. indicate. The list includes four items (status, date and time of occurrence, event name, and content). “Status” identifies “abnormal” or “alarm”. In the example of FIG. 15, “!” Indicates “abnormal” and “!!” indicates “warning”.

  Also, when the occurrence of an abnormal state or an alarm state of the filling and sealing machine 10 is detected by the PLC 10A based on the detection output of the sensor, a code corresponding to the abnormal state is similarly stored in the storage device in the data server 30. It may be stored. Also, when a defect occurring in the completed carton 5 is detected based on the detection output of the sensor or the inspection device, similarly, the code corresponding to the abnormal state is stored in the storage device in the data server 30. Is also good.

  “Event name” is a name given to each event. The data server 30 may store the code of the event name according to the content of “abnormal” or “alarm”. In one example, a button corresponding to an abnormal state of the filling and sealing machine 10 or a button corresponding to the content of a defect that has occurred in the completed carton 5 among a plurality of buttons for an alarm provided in the filling and sealing machine 10. When operated, codes corresponding to each button are stored in a storage device in the data server 30. The hard disk 45 of the management PC 40 stores event names corresponding to each code. The CPU 41 displays an event name corresponding to the code in the area 1203.

  An example of the “abnormal state of the filling seal machine 10” (alarm) is a measurement value (“energy of the ultrasonic oscillator” and / or “amplitude of the ultrasonic oscillator”) related to the oscillation of the ultrasonic wave by the ultrasonic oscillator (the ultrasonic oscillator 204). )) Is abnormal. Another example is that the measurement value of the heating temperature of the top heater (at least one of the top heater (1) 501 and the top heater (2) 502) is abnormal (a value outside a given range).

  An example of “defective occurring in the completed carton 5” (abnormal) is that the plug 4 has not been inserted into the carton 5. Another example is that the molded shape of the top has problems such as misalignment of the sticking of the seal and poor breaking.

  When the screen 1200 of FIG. 15 is displayed, the manager of the filling and sealing machine 10 can generate an alarm in the filling and sealing machine 10 and an occurrence of an abnormality in the completed carton 5 together with the operation status of the filling and sealing machine 10 Can be confirmed. Furthermore, the administrator can confirm the occurrence of the alarm and the occurrence of the abnormality as a time-sequential list even after a lapse of months and days since filling. Such a display is realized by the various types of data shown in FIG. 13 being stored in the data server 30 for a relatively long time in the filling seal system according to the present disclosure, and the management PC 40 acquiring the data. Is done.

[Parts management]
FIG. 16 is a diagram illustrating an example of a screen displayed when the “data reference creation” icon is operated for “maintenance inspection status” in FIG. 14. A screen 1300 in FIG. 16 is a screen (parts management screen) for managing the use time of each of the parts (elements) provided in the filling and sealing machine 10.

  On the screen 1300, “state”, “part name”, “cumulative use time (current value)”, “percentage” of the use time with respect to the threshold, “ "Maintenance inspection information" and "history" of replacement. The use time is, for example, a cumulative value of the operation time of the filling and sealing machine 10 after each component is mounted on the filling and sealing machine 10.

  The “state” indicates a state related to replacement of each part. An example of the displayed state is “notification” (“!” In FIG. 16) indicating that the time for replacement is approaching. Another example is a “warning” (“!!!!” in FIG. 16) indicating that the time for replacement has already come.

  The “maintenance inspection information” includes a management method of each part. "Numerical management" in the "maintenance inspection information" means that the replacement of the part is managed by numerical values such as usage time. In the “maintenance inspection information”, the “notification threshold value” indicates a value (for example, 80%) of a certain ratio with respect to the “replacement warning value”, and the “replacement warning value” indicates that a warning is issued based on the use time of the part. It is used as a reference when outputting. When the use time of a component reaches the “replacement warning value”, the CPU 41 of the management PC 40 outputs a warning that the component needs to be replaced. An example of the warning output is the display in the above-mentioned “state” column.

  In one example, the “replacement warning value” is input to the data server 30 by the administrator, and the “notification threshold” is calculated by the CPU 41 based on the “replacement warning value”. Since the screen 1300 displays not only the “replacement warning value” but also the “notification threshold value” and the ratio based on the “notification threshold value”, the administrator of the filling and sealing machine 10 can take measures before a component failure occurs. Can be considered. Instead of, or in addition to, the ratio of the use time to the notification threshold, the ratio of the use time to the replacement warning value may be displayed.

  The CPU 41 displays the ratio of the maintenance / inspection information to the “threshold” in a graph in the column of “ratio”. Thereby, information for setting a replacement schedule is provided for each component. Also, the use of the graph has a greater visual impact. The graph may be color-coded according to the relationship of the usage time to the threshold. As the relation, for example, there are three types, that is, (1) not reaching a certain ratio with respect to the notification threshold, (2) being below the notification threshold but exceeding a certain ratio with respect to the notification threshold, and , (3) the notification threshold has been reached.

  Screen 1300 displays a list of information on the usage time (time until replacement is required) for a plurality of components. This allows the administrator to simultaneously study the replacement of a plurality of parts, for example, by examining a combination of parts for which replacement is to be arranged at the same time.

  The “history” includes the last replacement date of each component and the cumulative number of replacements of the component in the filling and sealing machine 10.

[Other examples of equipment operation monitor]
Each of FIGS. 17 and 18 is a diagram showing a modification of the display screen of the equipment operation monitor described with reference to FIG.

・ Figure 17
The screen 1400 in FIG. 17 includes a table 1401 indicating the operation status of the filling and sealing machine 10 in May 2017. The table 1401 includes an operation status, a power ON time, an operation time, an operation rate, a TH temperature (top heater temperature), and a BH temperature (bottom heater temperature) for each day. In the table 1401, the data of each day is arranged in the vertical direction, and the date to be displayed is changed by scrolling in the vertical direction. The CPU 41 uses the data stored in the data server 30 to generate information constituting the table 1401, and displays the screen 1400 on the monitor 48.

  In the table 1401, the operation status is represented by a display color of a cell provided every hour. The color of the cell (the type of hatching in FIG. 17) is determined by the operating rate of the filling and sealing machine 10 every hour. The operation rate indicates the ratio of the operation time to the power-on time.

  In the table 1401, the “power-on time (H)” indicates the length of time that the power is supplied to the filling and sealing machine 10 on each day. “Operating time (H)” indicates the length of time that the filling and sealing machine 10 has been operating on each day. The “operating rate (%)” indicates the ratio of the operating time to the power-on time on each day.

  Table 1401 shows two types of values arranged on the left and right for each of the TH temperature and the BH temperature. In each display, the value on the left is the measured value of the heater (1), and the value on the right is the measured value of the heater (2).

FIG. 18
The screen 1500 in FIG. 18 includes areas 1501 and 1502 indicating the operation status of the filling and sealing machine 10 in December 2017. An area 1501 represents the power ON time and the operating time of each day in a bar graph. An area 1502 indicates the operation rate of each day.

  In each of the regions 1502 and 1502, data of each day is arranged in the left and right direction, and the date to be displayed is changed by scrolling in the left and right direction. The CPU 41 uses the data stored in the data server 30 to generate information constituting the areas 1501 and 1502, and displays the screen 1500 on the monitor 48.

[Automatic sorting]
The CPU 41 sequentially acquires the measured values in the filling and sealing machine 10 and determines whether or not a defect has occurred in the carton 5 to be processed in the filling and sealing machine 10 based on the measured values. Is also good.

  In this example, the CPU 41 or the PC or PLC for edge computing refers to at least one type of measurement value (FIG. 13) during the period when the filling and sealing machine 10 is processing each carton 5. The information collecting terminal 12 sequentially transmits the measured values of the filling and sealing machine 10 to the data server 30. The CPU 41 sequentially refers to the measurement values stored in the data server 30. Note that the management PC 40 may sequentially acquire measurement values by directly communicating with the information collection terminal 12 via the network 20 (without passing through the data server 30).

  In this example, when it is determined that the product (carton 5) sent to the discharge section is defective, the filling and sealing machine 10 determines that the carton 5 is not defective. A mechanism (defective product discharge mechanism) for discharging to a place (defective product collection position) different from the placed carton is provided.

  FIG. 19 is a flowchart of the product determination process of the carton 5 using the measured values. The processing in FIG. 19 is realized, for example, by the CPU 41 or a PC or PLC for edge computing executing a given program. The processing in FIG. 19 is executed for each carton processed in the filling and sealing machine 10. The CPU 41 starts the process of FIG. 19 for the carton 5 at the timing of being discharged to the discharge section after the carton 5 is put into the bottom seal portion 100, for example. The details of the product determination process will be described with reference to FIG.

  In step S10, the CPU 41 or the PC or PLC for edge computing determines that all the measured values are in the range of the criterion set for the measured values (see FIG. 13; also referred to as “reference range”). ) Is determined. The CPU 41 may read out information specifying the reference range from the storage device of the data server 30 in advance and store the information in the hard disk 45. If all the measured values are within the reference range (YES in step S10), CPU 41 ends the process in FIG. 19; otherwise (NO in step S10), control proceeds to step S12.

  In step S12, the CPU 41 or the PC or PLC for edge computing transmits an instruction to the PLC 10A to discharge the carton 5 to be processed to the defective product collection position by the defective product discharging mechanism.

  In step S14, the CPU 41 or the PC or PLC for edge computing outputs an alert indicating that a failure has occurred in the completed carton 5. In one example, a message indicating that a failure has occurred is displayed on the monitor 48. Thereafter, the CPU 41 ends the processing in FIG.

  Note that the filling and sealing machine 10 does not need to include the defective product collection mechanism. In this case, the CPU 41 or the PC or PLC for edge computing may instruct to stop the operation of the filling and sealing machine 10 in step S12, or may omit the control in step S12.

  The CPU 41 may include, in the alert output in step S14, information (product ID) for specifying the carton 5 determined to have a defect and / or the type of measurement value serving as a basis for the defect determination.

[Correction of reference range]
In the filling and sealing machine 10, a reference range may be set for any of the measured values. In such an example, information for specifying the reference range may be stored in the PLC 10A. If at least one measured value of a certain product (carton 5) exceeds a reference range, the PLC 10A determines that a defect has occurred in the product.

  FIG. 20 is a diagram illustrating an example of the measurement value. The example in FIG. 20 includes measurement values for nine products (product IDs “0001” to “0009”). The measurement values include the values listed in FIG. Each measurement value has the significance described with reference to FIGS. 5, 6, 9, 11, and 12, for example. In FIG. 20, the value of each measurement value is schematically shown as a character string such as “A0001”. The measurement values further include two types of judgment results (judgment results (automatic) and judgment results (visual)) for each product (carton). The “determination result (automatic)” is generated by, for example, the PLC 10 </ b> A based on detection outputs of various sensors in the filling and sealing machine 10. The “judgment result (visual)” is generated after the production of the carton based on the visual inspection of the worker and the sampling inspection.

  In the example of FIG. 20, for the product IDs “0001” to “0004” and “0009”, both the determination result (automatic) and the determination result (visual) are OK. For the product IDs “0005” to “0008”, the determination result (automatic) is OK, but the determination result (visual) is NG.

  FIG. 21 is a flowchart of the reference correction process. The reference correction process is realized, for example, by the CPU 41 executing a given program. The CPU 41 starts the threshold value correction processing at the timing when the measurement values of the given number of product IDs are accumulated or at the timing when the start is instructed by the administrator, for example. The details of the threshold value correction processing will be described with reference to FIG.

  In step S20, the CPU 41 determines whether or not the determination result (automatic) and the determination result (visual) match for all the product IDs. If the determination result (automatic) and the determination result (visual) match for all product IDs (YES in step S20), CPU 41 ends the process in FIG. On the other hand, if it is determined that the result is different between the determination result (automatic) and the determination result (visual) for at least one product ID (NO in step S20), CPU 41 determines the determination result (automatic) and the determination result (visual). ) Is executed for each product ID having a different result from the above.

  In step S22, the CPU 41 executes statistical processing of the measured values. In one example, the CPU 41 obtains the median value for each type of measurement value using the measurement values of all products whose determination result (visual) is “OK”.

  In step S <b> 24, for a product ID having a different result between the determination result (automatic) and the determination result (visual), the CPU 41 has a type of measurement value having a difference from the median by a given reference or more. It is determined whether or not.

  An example of the predetermined criterion is “2σ” when the standard deviation of the measurement value for each type obtained in step S22 is represented as “σ”. FIG. 22 is a diagram for explaining the determination in step S24. In FIG. 22, the median obtained in step S22 is indicated as “Med”, and the existing reference range is indicated by the values D1 and D2. The measured value of the product ID whose result is different between the judgment result (automatic) and the judgment result (visual observation) is indicated by the measured value R. Since the measurement value R is located between the value D1 and the value D2, the PLC 10A determines that no defect has occurred in the product. On the other hand, in step S24, the CPU 41 determines whether there is a measurement value having a value outside the range specified as “Med ± 2σ”.

  When CPU 41 determines that there is such a measured value (YES in step S24), it advances the control to step S26, otherwise, it advances the control to step S30.

  In step S30, CPU 41 notifies that there is no irregular measurement value, and ends the processing in FIG. 21 for the product to be processed. One example of the notification is the display of a message on the monitor 48. An example of the significance of the notification in step S28 will be described as follows.

  For example, the fact that the judgment result (automatic) is OK and the judgment result (visual) is NG means that, for a certain product, although no abnormality is detected as a measurement value of the filling and sealing machine 10, the worker Means that the product was determined to be NG in a visual inspection or the like. If the result of the determination in step S24 is "NO", it means that all the measured values of the product are not significantly different from the measured values of other products visually determined as OK by the worker. In such a case, there is a high possibility that a new means other than the current measured value is required to automatically determine the occurrence of a defect in the product. An example of the notification in step S28 is notification of the necessity of such a new means.

  In step S26, the CPU 41 determines a correction value of the threshold. An example of the correction value is a set of an upper limit “Med + 2σ” and a lower limit “Med−2σ”. Another example is one of the upper limit value “Med + 2σ” and the lower limit value “Med−2σ”. For example, if it is determined in step S24 that the measured value of the product to be processed exceeds “Med + 2σ”, the CPU 41 may determine only the upper limit “Med + 2σ” as a correction value for the measured value. If it is determined in step S24 that the measured value of the product to be processed is lower than “Med−2σ”, the CPU 41 may determine only the lower limit “Med + 2σ” as a correction value for the measured value. .

  In step S28, the CPU 41 notifies the correction value determined in step S26. Thereafter, the CPU 41 executes the control of steps S22 to S30 for each product for which the determination result (automatic) and the determination result (visual observation) do not match, and then counts the processes in FIG.

An example of the significance of the notification in step S28 will be described as follows.
For example, the judgment result (automatic) is OK and the judgment result (visual) is NG, even if the measured value of the filling and sealing machine 10 is within the existing reference range for the product corresponding to these judgment results. Means that the product is determined to be NG in a visual inspection of a worker after manufacturing or the like. In such a case, if the reference range of any type of measurement value is changed, it is expected that if the determination result (visual) is NG, the possibility of being derived as OK as the determination result (automatic) is reduced. Is done. Therefore, as a correction value of the reference range for the measurement value of the above type, a correction value (for example, an upper limit value “ Med + 2σ ”and / or the lower limit“ Med−2σ ”) are presented to the administrator.

The proposal of the correction value will be described more specifically.
In the product ID “0005” in FIG. 20, the “horn pressing pressure” (schematically shown as “E0005” in FIG. 20) is within the existing reference range, but exceeds “Med + 2σ”. . In this case, in step S28, the CPU 41 outputs a message suggesting that the upper limit of the reference range of the “horn pressing pressure” be changed to “Med + 2σ”.

  In the product ID “0006” in FIG. 20, the “horn cooling air pressure” (“F0006” in FIG. 20) is within the existing reference range, but falls below “Med + 2σ”. In this case, in step S28, the CPU 41 outputs a message suggesting that the lower limit of the reference range of “horn cooling air pressure” be changed to “Med−2σ”.

  In the product ID “0007” in FIG. 20, the “gap between the horn and the anvil” (“G0007” in FIG. 20) is within the existing reference range, but exceeds “Med + 2σ”. In this case, in step S28, the CPU 41 outputs a message suggesting that the upper limit value of the reference range of the “gap between the horn and the anvil” be changed to “Med + 2σ”.

  In the product ID “0008” in FIG. 20, “the horn-anvil parallelism” (“H0008” in FIG. 20) is within the existing reference range, but falls below “Med + 2σ”. In this case, in step S28, the CPU 41 outputs a message suggesting that the lower limit of the reference range of the “horn-anvil parallelism” be changed to “Med−2σ”.

  As described above, according to the reference correction process described with reference to FIG. 21, if there is a product having a different determination result (automatic) and a different determination result (visual), the CPU 41 is used in the determination of the product by the PLC 10A. A correction value for the reference range is provided. Thereby, the administrator of the filling and sealing machine 10 can change the reference range stored in the PLC 10A using the correction value.

  As an example of the provided correction value, a measurement value when the determination result (visual) is OK is used (“Med + 2σ” and / or “Med−2σ”). Thereby, the criterion of the automatic determination by the PLC 10A that the defect has occurred in the product can be corrected using the result of the determination performed afterwards.

  In the filling seal system, the data stored in the data server 30 can be used in other modes. For example, in a measurement value as shown in FIG. And carton cell frame No. Each time, the occurrence rate of NG can be calculated and reported. By receiving the notification, the manager of the filling and sealing machine 10 may consider, for example, replacing a mandrel and / or a carton cell frame having a high incidence of NG. In one example, the administrator may specify a particular mandrel No. In other mandrel Nos. If a situation occurs in which NG occurs more frequently than in the case of, the situation can be recognized, and the mandrel can be checked, replaced, adjusted, and the like.

  In addition, in the filling seal system, not only the measured value but also a set value may be used to propose a correction value such as a reference range, in addition to the measured value. For example, a correction value for a reference range may be proposed by statistically processing a set value when a product having a different determination result (automatic) and a different determination result (visual observation) is manufactured.

  Thus, generation and provision of information using a measured value for a fill seal system has been described. In the present disclosure, mainly the measurement values (weld time, etc.) of the attachment of the plug 4 have been exemplified. In addition, the measurement value used for the filling and sealing machine 10 is not limited to this. The measurement value used may be a measurement value (such as a heater temperature) relating to the formation of the lower part 6 of the carton 5 in the lower stage of the filling and sealing machine 10.

  The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. 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.
