Description

  The present invention relates to an information processing apparatus for a weighing instrument used in a weighing instrument that measures the weight of an object to be weighed such as a combination weigher or a weight sorter.

  A weighing device such as a combination weigher or a weight sorter installed on a production line needs to be set with a plurality of operating conditions for operation, and is not always operated with the same setting. Usually, the combination weigher is connected to a packaging machine, and an object to be weighed with the combination weigher is put into the packaging machine and packaged. The content of the weighed object or package is not always constant and is changed. Also, weighing and packaging may be performed by switching the object to be weighed and the packaging material in units of several hours. In the final stage of the production line, the weight type sorter checks whether the weight of the weighed and packed objects to be weighed is within the specified weight range, and weighs various kinds of objects to be weighed. There must be. In such a weighing device, the operating conditions must be set and changed as necessary.

For example, Patent Literature 1 describes a technique in a combination weigher in which operation parameters are classified into external input parameters and internal generation parameters, and the internal generation parameters are automatically set based on the external input parameters. In this case, it is practically impossible to set all operation parameters to optimum values by automatically setting internally generated parameters. The reason is that a high-performance weighing device measures various objects to be weighed, but the characteristics of the objects to be weighed vary, and the optimum value of the operating parameter varies depending on the characteristics. For example, the input amount to the weighing hopper that affects the combination accuracy of the combination weigher is set by the dispersion feeder strength, dispersion feeder operation time, linear feeder strength, and linear feeder operation time. It varies greatly depending on the characteristics of the sample. The characteristics of the objects to be weighed include specific gravity, adhesion (entanglement between objects to be weighed), size, and the like. If the characteristics of the object to be weighed are different, the transport amount is different even if the dispersion feeder strength, dispersion feeder operation time, linear feeder strength and linear feeder operation time are the same, so the optimum value for the object to be weighed is The reality is that it cannot be calculated. Therefore, after obtaining a numerical value that is a certain standard by automatic setting, an optimum value is obtained by actual operation, and the set value is determined.
Japanese Patent Laid-Open No. 2003-4517

  In weighing equipment, when the type of the object to be weighed is changed, or when the weighing conditions of the object to be weighed are changed, the operating condition setting values such as the operating parameters that regulate the operation of the weighing equipment must be changed. . For example, in a combination weigher, when the target weight is changed, the strength of the linear feeder that supplies the object to be weighed to the hopper is adjusted to adjust the amount of the object to be weighed to the weighing hopper in order to improve the combination accuracy. adjust. When an operator operates a combination weigher, for example, by shift work, there are multiple operators, so there may be times when it is difficult to know who is changing the operating condition setting value and when it is operating, and it is the worst case This will result in poor weighing and the production line will stop. If the operating condition set value is backed up or printed, it can be restored to its original state, but it takes time to set it again. In particular, in a high-speed production line, when production stops, the time to return is a significant loss.

It comprises a CPU unit 5 comprising a device, a storage unit 6 having a RAM and a non-volatile memory, and an interface unit 7 with the weighing device main unit 1B. The non-volatile memory in the storage unit 6 stores an execution program of the CPU unit 5 in advance, and also stores data of operation condition (operation condition) change information described later. The clock unit 4 is constituted by, for example, an RTC (real time clock), and provides the date and time data to the CPU unit 5. In the present embodiment, the display unit 2 and the input unit 3 are configured by a touch panel display.

  The information processing apparatus 1A according to the present embodiment includes the operation condition changing means, change information creating means, change history storage means, change history display means, selection means, resetting means, login means, and setting information storage means described above. Function as. Further, it may function as the operator information input means and designation means described above.

  FIG. 2 is a diagram illustrating a combination weigher that is an example of a weighing device according to the present embodiment.

  The weighing instrument main body 1B of the combination weigher is provided with a conical dispersion feeder 11 in the center of the upper part of the apparatus for dispersing the object to be measured radially by vibration. In the dispersion feeder 11, an object to be weighed supplied from a supply device (not shown) to the central portion thereof is sent out toward the peripheral portion by vibration. Around the dispersion feeder 11, a plurality of linear feeders 12 are radially provided for feeding the objects to be weighed sent from the dispersion feeder 11 to the supply hoppers 13 by vibration. Below each linear feeder 12, a supply hopper 13 and a weighing hopper 14 are provided correspondingly. The plurality of supply hoppers 13 and weighing hoppers 14 are each arranged in a circular shape. The supply hopper 13 receives the object to be weighed sent from the linear feeder 12, and when the weighing hopper 14 disposed below it is empty, the gate is opened and the object to be weighed is put into the weighing hopper 14. Each weighing hopper 14 is attached with a weight sensor 15 such as a load cell that measures the weight of the object to be weighed in the weighing hopper 14, and a measurement value by each weight sensor 15 is output to the information processing apparatus 1 </ b> A. A collecting chute 16 is provided below the weighing hoppers 14 arranged in a circle, and a collecting funnel 17 is disposed below the collecting chute 16. Below the collective funnel 17 of this combination weigher, for example, a packaging machine (not shown) is arranged, and the objects to be weighed discharged from the collective funnel 17 are put into the packaging machine and packaged.

  In the information processing apparatus 1A, operation control of the weighing device main body 1B is performed, and combination processing for obtaining a combination of the weighing hoppers 14 to discharge the objects to be weighed is performed. In this combination processing, a combination calculation is performed based on the weighing value of each weighing hopper 14 (the weight value of the object to be weighed in the weighing hopper 14 measured by the weight sensor 15), and the weighing is performed from the plurality of weighing hoppers 14. A combination in which the total of the values is within the allowable range with respect to the target weight and the combination of the weighing hoppers 14 that minimizes the absolute value of the difference from the target weight is selected, and the object to be weighed is discharged. And

  In the information processing apparatus 1 </ b> A, it is also possible to display the combined weighing result and the total of the combined weighing result on the screen of the display unit 2.

  The outline of the operation of the combination weigher configured as described above will be described.

  First, an object to be weighed is conveyed above the combination weigher by a supply device (not shown) and placed on the dispersion feeder 11. Then, the object to be weighed is distributed to the supply hopper 13 through the linear feeder 12 following the dispersion feeder 11 after being dispersed radially by the vibration of the dispersion feeder 11. When the weighing hoppers 14 located below the supply hoppers 13 are empty, the objects to be weighed in the supply hoppers 13 are put into the weighing hoppers 14. The information processing apparatus 1A performs the combination process described above, and causes the weighing hopper 14 corresponding to the combination to be discharged to discharge the objects to be weighed. The objects to be weighed discharged from the weighing hopper 14 slide down on the collecting chute 16 and are discharged to the packaging machine via the collecting funnel 17. The above operation is repeated.

  In the combination weigher, in order to perform the operation as described above, it is necessary to set values of a large number of operating condition setting items, which are performed using the information processing apparatus 1A, and the values of the set operating condition setting items are stored in the storage unit. 6 is stored.

  The main setting items of the operating conditions of such a combination weigher are target weight, upper limit allowable weight, speed, dispersion feeder strength, linear feeder strength, dispersion feeder operation time, linear feeder operation time, supply hopper opening time, weighing hopper Open time, stabilization time, etc.

  Each setting item will be briefly described. The target weight is a target weight to be discharged, and the upper limit allowable weight is a value that determines a maximum weight that allows discharge with respect to the target weight, and discharge allowable maximum weight = target weight + upper limit allowable weight. Here, the target weight is the minimum allowable discharge weight. The speed is the number of bags (packs) in which the objects to be weighed are packaged in a packaging machine per minute. The dispersion feeder strength is a value corresponding to the vibration amplitude of the dispersion feeder 11, and the linear feeder strength is a value corresponding to the vibration amplitude of the linear feeder 12. The distributed feeder operating time and the linear feeder operating time are the operating times of the distributed feeder 11 and the linear feeder 12, respectively. The supply hopper opening time and the weighing hopper opening time are times during which the fully opened state is maintained until the closing operation is started after the gate opening operation of each hopper is performed. The stabilization time is the weighing value for the combination calculation by the information processing device 1A after the predetermined time has elapsed since the gate hopper 13 of the supply hopper 13 is opened to load an object to be weighed into the weighing hopper 14. The above-mentioned predetermined time that is determined to be acquired as, and is set in order to acquire an accurate measurement value of the object to be measured from the weight sensor 15. These setting items are merely examples, and there are actually a large number of setting items such as tens or hundreds.

  FIG. 3 is a diagram illustrating an example of an operation condition setting screen for setting values of operation condition setting items (operation condition setting items).

  The information processing apparatus 1A has a login function. For example, when the information processing apparatus 1A is turned on, first, a general login screen for inputting a user name and password is displayed on the screen of the display unit 2. When the user name and password are input on the login screen, the CPU unit 5 collates the input user name and password with the user name and password stored in advance in the storage unit 6. A menu screen (not shown) is displayed on the screen. On this menu screen, for example, a touch key switch for “operation condition setting”, a touch key switch for “operation condition change history”, a touch key switch for “start operation”, and the like are displayed.

  The operation condition setting screen 30 of FIG. 3 is called from the above-described menu screen, for example. Touching the “Operating condition setting” touch key switch on the menu screen displays, for example, a product type selection screen for selecting the product number assigned to each product type, and selecting the desired product number (for example, For example, the operation condition setting screen 30 of FIG. 3 is displayed. The operation condition setting screen 30 in FIG. 3 is an example of the operation condition setting screen when the product number 1 is selected.

  Touching the “operating condition change history” touch key switch displays a product type selection screen for selecting, for example, the product type number assigned to each product type of the object to be weighed. For example, the operation condition change history screen 40 of FIG. 4 is displayed. The operation condition change history screen 40 in FIG. 4 is an example of the operation condition change history screen when the product number 1 is selected. Further, when the “operation start” touch key switch is touched, the operation (operation) of the combination weigher is started.

  In the operation condition setting screen 30 of FIG. 3, each setting item name is displayed, and on the right side of each setting item name, the value of the setting item (currently set value, determined in advance before the operation is started). A set value display area for displaying (initial set values) is provided. Each set value display area is a touch key switch 31, and when the touch key switch 31 is touched, a ten key dialog box is displayed, and the ten key can be touched to input and change the value of the set item. it can. After inputting and changing the value of the setting item, when touching the “determine” touch key switch 34, the CPU unit 5 uses the value of the setting item displayed in the setting value display area when the touch is performed as an operation condition. In addition to setting, operating condition change information is created, and the created operating condition change information is added to the change information history table in the storage unit 6. That is, a change information history table in which the operation condition change information is sequentially recorded is created in the storage unit 6, and the newly created operation condition change information is added to the change information history table. The individual operating condition change information is, for example, the contents displayed on each touch key switch 41 in FIG. In some cases, an ID number is assigned as shown in FIG. In FIG. 3, when the touch key switches 32 and 33 are touched, the screen can be scrolled up and down. Further, when the “return” touch key switch 35 is touched, the display returns to the display screen that called the operation condition setting screen 30, here, the menu screen.

  In the present embodiment, when the operating condition is changed using the above-described operating condition setting screen 30 of FIG. 3 and when the operating condition is changed using the operating condition change history screens of FIGS. The values of all the operating condition setting items after the change are stored in the storage unit 6 and saved.

  FIG. 4 is a diagram illustrating a first example of the operating condition change history screen. In the operating condition change history screen 40 of FIG. 4, the operating condition change information created from a past point in time to the present point is displayed. Here, the past point in time varies depending on the capacity of the storage unit 6 and the like, but is, for example, the point in time when the combination weigher is installed and used.

  In this operating condition change history screen 40, the date and time when the operating condition was changed, the operator abbreviation (OZM, HYM, etc.) that is information for specifying the operator who changed the operating condition, and the change The operating condition change information consisting of the contents is displayed in a time series in a tabular format, and these are the contents stored in the above-described change information history table. As changed contents, changed setting items and values before and after changing the setting items are displayed. For example, “WB.O 250 → 270” displayed as the change content in FIG. 4 indicates that the weighing hopper opening time (WB.O) has been changed from 250 msec to 270 msec. Further, LF indicates the linear feeder strength, and TW indicates the target weight.

  In addition, when the CPU unit 5 creates individual operating condition change information, the information on the date and time when the operating condition is changed is acquired from the clock unit 4, and the information for specifying the operator is obtained. , Get during the login process. The same applies to the second example (FIGS. 5 and 6) and the third example (FIG. 7) of the operating condition change history screen described later.

  In the case of FIG. 4, each change information display area is a touch key switch 41, and when the touch key switch 41 is touched, the touch key switch 41 blinks or changes color and is displayed on the touch key switch 41. All the operating conditions including the setting item changed at the time (date, time and date) are selected. Next, when the “OK” touch key switch 44 is touched, all the operating conditions selected above are set. That is, not only the value of the setting item changed at the time point displayed on the touch key switch 41, but also the values of all the setting items set at that time point are set (this changes the operating condition). ). By the above operation, the values of all the operating condition setting items at a desired point in the past can be reset easily and in a short time.

  When the touch key switch 41 is touched and then the “list” touch key switch 46 is touched, a screen for displaying all the operating conditions selected when the touch key switch 41 is touched is called. . This screen is a screen on which setting items and their values are displayed, such as the operating condition setting screen 30 of FIG. Further, when the touch key switches 42 and 43 are touched, the screen can be scrolled up and down. When the “return” touch key switch 45 is touched, the display returns to the display screen that called the operating condition change history screen 40, here, the menu screen.

  5 and 6 are diagrams showing a second example of the operating condition change history screen.

  In this case, as described above, when the touch key switch of “operating condition change history” is touched on the menu screen, the type selection screen is displayed, and when the desired type number is selected, the operating condition change history screen 50 of FIG. Is displayed. The operating condition change history screen 50 in FIG. 5 is an example when product type 1 is selected.

  In the case of the second example of the operation condition change history screen, the operation condition change information is created and stored by adding an ID number (identification number) to the contents of the operation condition change information in the case of FIG. In the operating condition change history screen 50 of FIG. 5, the ID number (137, 138 in the figure) is displayed in a column corresponding to the date and time when the operating condition is changed, in a calendar format. In the example of FIG. 5, a calendar for each month is displayed in the calendar display area 51 on the left side of the screen. When the touch key switch 54 at the upper left is touched, the calendar is switched to the previous month, and the touch key switch 55 at the upper right is pressed. Touch to switch to the calendar for the next month. In the operating condition change date and time display area 56, the ID displayed in the month displayed in the calendar display area 51 indicates that the operating condition has been changed at what hour and at what time. . For example, the ID number of “137” is displayed in the 11:00 column in the vertical column of 11/2, so that the 12:00 range on November 2 (from 11:00 to 12:00) It can be seen that there was a change in the operating conditions until just before. Touching the touch key switches 52 and 53 can scroll the display screen in the operating condition change date and time display area 56 up and down, and touching the touch key switches 57 and 58 scrolls the display screen in the operating condition change date and time display area 56 left and right. it can. When the “return” touch key switch 55 is touched, the display returns to the display screen that called the operation condition setting screen 50, here, the menu screen.

  When any one of the touch key switches 59 in the part where the ID number is displayed in the operating condition change date and time display area 56 is touched, as shown in FIG. 6, the ID number and the date when the operating condition is changed And it switches to the driving condition change log | history screen 60 on which the driving condition change information which consists of the operator's abbreviation which is information for specifying the operator who changed time and driving conditions, and the change content was displayed. FIG. 6 is an example of the operation condition change history screen 60 when the touch key switch 59 in the portion where the ID number “137” is displayed. The display contents other than the ID number are the individual operation in FIG. This is the same as the contents of the condition change information. The “OK”, “RETURN”, and “LIST” touch key switches 64, 65, and 66 have the same functions as the “ENTER”, “RETURN”, and “LIST” touch key switches 44, 45, and 46, respectively. Have For example, when the “determine” touch key switch 64 is touched, not only the changed setting item values displayed on the operating condition change history screen 60 but also the values of all the setting items set at that time are displayed. It is set (this changes the operating conditions). By the above operation, the values of all the operating condition setting items at a desired point in the past can be reset easily and in a short time.

  When the “list” touch key switch 66 is touched, a screen for displaying all the operating conditions at the time of change displayed on the operating condition change history screen 60 is called. This screen is a screen on which setting items and their values are displayed, such as the operating condition setting screen 30 of FIG. Further, when the “return” touch key switch 65 is touched, the operation condition change history screen 50 of FIG. 5 is returned.

  FIG. 7 is a diagram illustrating a third example of the operating condition change history screen.

  In this case, as described above, when the touch key switch of “operating condition change history” is touched on the menu screen, the type selection screen is displayed, and when the desired type number is selected, the operating condition change history screen 70 of FIG. Is displayed. The operating condition change history screen 70 in FIG. 7 is an example when product type 1 is selected.

  On this operating condition change history screen 70, operating condition change information created from a past point in time to the present point is displayed. Here, the past point in time varies depending on the capacity of the storage unit 6 and the like, but is, for example, the point in time when the combination weigher is installed and used.

  In this operating condition change history screen 70, the date and time when the operating condition was changed, the operator abbreviation (OZM, HYM, etc.) which is information for specifying the operator who changed the operating condition, and the change The operating condition change information including the contents is displayed in each change display box 71 (71a to 71g) and displayed in time series according to the vertical position in the screen. As changed contents, changed setting items and values before and after changing the setting items are displayed. The content of the operating condition change information is the same as that of the operating condition change history screen 40 of FIG.

  In the operating condition change history screen 40 of FIG. 4, the changed contents of the operating conditions and the like are displayed in order of the changed time (in time series), but in the operating condition change history screen 70 of FIG. A flow chart using the change display box 71 (71a to 71g) so that the change contents of the conditions and the like can be known in a time series and at which point in the past the change has been made based on the value of the setting item. It is displayed like this.

  The contents displayed in each change display box 71a to 71g are the same as the contents displayed in each change information display area which is the touch key switch 41 of FIG.

  In the portion displayed in FIG. 7, the operating conditions are changed in the order of the change display box 71a, the change display box 71b, the change display box 71c,. Here, the change of the operation condition in the change display box whose change point is connected to the previous change display box by a solid line is changed using, for example, the operation condition setting screen 30 of FIG. For example, the change contents of the change display boxes 71a, 71b, 71c, 71e, and 71f are obtained by calling the operation condition setting screen 30 in FIG. 3 and changing the operation conditions.

  In addition, the change of the operating condition in the change display box whose change point is connected to the previous change display box by a broken line is changed using the touch key switch 74 of “determination” described later. The changed operating conditions that have been set are set. For example, the change of the operation condition in the change display box 71d connected to the change display box 71b by a broken line is because all changed operation conditions in which the change contents of the change display box 71b are set are selected and set. . The change of the operation condition in the change display box 71g connected to the change display box 71d by a broken line is because all changed operation conditions in which the change contents of the change display box 71d are set are selected and set. . As described above, the operating condition change history screen 70 of FIG. 7 shows not only the change contents of the operating conditions but also the operating conditions at which point in the past.

  Each change display box 71 (71a to 71g) is a touch key switch (hereinafter referred to as "touch key switch 71"), and when any touch key switch 71 is touched, the touch key switch 71 blinks. Or, the color changes, and all the operating conditions including the setting item changed at the time (year, month, day, and time) displayed on the touch key switch 71 are selected. Next, when the “OK” touch key switch 74 is touched, all the operating conditions selected above are set. That is, not only the value of the setting item changed at the time point displayed on the touch key switch 71 but also the values of all the setting items set at that time point are set (this changes the operating condition). ). By the above operation, the values of all the operating condition setting items at a desired point in the past can be reset easily and in a short time.

  When the touch key switch 71 is touched and then the “list” touch key switch 76 is touched, a screen for displaying all the operating conditions selected when the touch key switch 71 is touched is called. . This screen is a screen on which setting items and their values are displayed, such as the operating condition setting screen 30 of FIG. Further, when the touch key switches 72 and 73 are touched, the screen can be scrolled up and down, and when the touch key switches 77 and 78 are touched, the screen can be scrolled left and right. When the “return” touch key switch 75 is touched, the display returns to the display screen that called the operating condition change history screen 70, here, the menu screen.

  As described above, in the present embodiment, the history of the operating condition change information and the values of the operating condition setting items set in the past are stored, the operating condition change history screen is called up, and the operating condition change information is stored. By selecting and operating the created past desired time point, the values of all the operation condition setting items at the past desired time point can be reset easily and in a short time. Therefore, even if the operation condition setting item is changed by trial and error to hinder the operation of the weighing device, it is possible to easily and quickly return to the operation condition at a desired point in the past.

  In addition, if you look at the operating condition change history screen, you can see when and who changed the value of which operating condition setting item, understand the relationship with the production status, and determine the operator's ability. It becomes possible.

  In the present embodiment, the information for specifying the operator in the driving condition change information is acquired by the login process. However, before the driving condition is changed, for example, “driving” on the above-described menu screen is performed. When the touch key switch of “Condition setting” and the touch key switch of “Operating condition change history” are touched, the password input screen is displayed, and when the password given in advance to each operator is input, the operating condition is set respectively. The screen and the operating condition change history screen may be called (displayed).
