Below each linear feeder 12, a supply hopper 13 and a weighing hopper 14 are provided correspondingly. The supply hopper 13 receives the articles fed from the linear feeder 12 and opens the discharge gate when the weighing hopper 14 disposed below the empty hopper 14 becomes empty, and supplies the articles to the weighing hopper 14. Each weighing hopper 14 is attached with a weight sensor 15 such as a load cell for measuring the weight of the article in the weighing hopper 14, and a measurement value by each weight sensor 15 is output to the operation control device 20. A collecting chute 16 is disposed below the weighing hopper 14, a funnel 17 is provided at the outlet of the collecting chute 16, and a packaging machine is disposed below the funnel 17. The weighing hopper 14 selected for the discharge combination described later opens its discharge gate to discharge the articles, and the discharged articles slide down the collecting chute 16 and the funnel 17 and are sent to the packaging machine. In a packaging machine (for example, a vertical pillow packaging machine), an object to be weighed discharged from a combination weigher is received into a bag and bagged while manufacturing the bag.

  FIG. 2 is a block diagram illustrating a configuration example of the operation control device 20.

  The operation control device 20 includes a control unit 21, an operation display 22, a printing device 25 capable of performing color printing, an I / F (interface) circuit 26, a voice synthesis LSI 29, and voice data. An audio data memory (ROM) 30, a speaker 31, a clock 32 including, for example, a real-time clock that provides date and time information (year / month / day and time) to the control unit 21, and an external IF circuit 33 are provided.

  The control unit 21 is constituted by, for example, a microcontroller, and includes an arithmetic control unit 27 including a CPU of the microcontroller and a storage unit 28 including a RAM and a ROM of the microcontroller. The arithmetic control unit 27 obtains the overall operation control and discharge combination of the main unit 1A of the combination weigher by the CPU executing an execution program (operation program) stored in the ROM of the storage unit 28 by the CPU. In addition to performing combination processing and the like, the operation display 22, the printing device 25, and the voice synthesis LSI 29 are controlled.

  The measurement value by each weight sensor 15 is input to the control unit 21 via the external IF circuit 33. A control signal for controlling the vibration operation of each of the dispersion feeder 11 and each of the linear feeders 12 and a control signal for controlling the opening / closing operation of each discharge gate of each of the supply hopper 13 and each of the weighing hoppers 14 are supplied from the control unit 21. It is output to each via the external IF circuit 33.

  The control unit 21 inputs a signal from the operation indicator 22 (operation input unit 23) and outputs a signal such as data to be displayed on the operation indicator 22 (display unit 24). The control unit 21 may be configured by a single control device that performs centralized control, or may be configured by a plurality of control devices that perform distributed control in cooperation with each other. The control unit 21 also functions as an operating condition changing unit and a totaling unit.

  In the combination processing, a combination calculation is performed based on the weight of the objects to be weighed in each weighing hopper 14 measured by each weight sensor 15, and the total weight (combined weight) of the objects to be weighed is a target weight range ( All combinations of the weighing hoppers 14 that fall within the allowable range for the target weight are obtained, and one combination is determined as the discharge combination. Here, when there are a plurality of combinations that fall within the target weight range, one of the combinations having the smallest absolute value of the difference between the combination weight and the target weight is selected and determined as the discharge combination.

Output to the speaker 31. As the voice synthesis LSI 29 and the voice data memory (ROM) 30, commercially available voice synthesis LSIs and voice ROMs can be used, but these functions may be realized by software.

  The clock 32 is formed of, for example, a real-time clock, and provides date and time information (year / month / day, time and day of the week) to the control unit 21.

  The control unit 21, the voice synthesis LSI 29, and the voice data memory 30 constitute voice output control means.

  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 the external supply device 10 and placed on the dispersion feeder 11. Then, the objects to be weighed on the dispersion feeder 11 are radially dispersed by vibration and sent to each of the linear feeders 12, and further, the objects to be weighed on the linear feeder 12 are sent to the supply hopper 13 by vibration. 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 control unit 21 performs the above-described combination process, and discharges the object to be weighed from the weighing hopper 14 selected as the discharge combination. 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 funnel 17. The above operation is repeated.

  In the combination weigher, it is necessary to set a number of operation condition (operation condition) setting items in order to perform the operation as described above, and can be set using the operation indicator 22 and all the set values can be set. Operation condition setting information including values of operation condition setting items (operation condition setting values) is stored in a predetermined area (hereinafter referred to as “operation condition storage area”) in the storage unit 28 of the control unit 21. The arithmetic control unit 27 controls the operation of the combination weigher by executing the operation program using the operation condition setting information stored in the operation condition storage area.

  The main setting items of the operating conditions of such a combination weigher include target weight, upper limit value, speed (operating speed), dispersion feeder strength, linear feeder strength, supply hopper opening time, weighing hopper opening time, and the like.

  Each setting item will be briefly described. The target weight is the weight to be measured and the upper limit value is a value for determining the upper limit weight of the target weight range, and the upper limit weight of the target weight range = target weight + upper limit value. Here, the target weight is the lower limit weight of the target weight range. The speed is indicated by the number of times per minute that the combination weigher discharges the object to be measured to the outside. The dispersion feeder strength is a value corresponding to the vibration amplitude of the dispersion feeder 11, and the rectilinear feeder strength is a value corresponding to the vibration amplitude of the rectilinear feeder 12. The supply hopper opening time and the weighing hopper opening time are times when the fully opened state is maintained until the closing operation is started after the discharge gate opening operation of each hopper is performed. These setting items are just examples, and there are many other setting items.

  3 to 8 are diagrams showing examples of screens displayed on the screen 22S of the display unit 24 of the operation indicator 22.

  In the display screen shown in FIG. 3, a message display area 51 for displaying messages related to driving is provided at the top, and the date and time provided from the clock 32 is displayed on the right side. Below these message display areas 51 and the like, an area for displaying the driving situation is provided. In the product type display area 52, the product type number, product type, target weight and speed of the object to be weighed are displayed. Here, although the speed is displayed as 115 wpm, this wpm is the number of measurements per minute. The product type display area 52 also serves as a touch key, and a desired product type can be selected by a touch operation. In the container state display area 53 below the state, the states of the dispersion feeder, the straight feeder, the supply hopper, the weighing hopper, etc. of the combination weigher are displayed (not shown).

  The language switching touch key 54 displays the currently selected language. When the touch key 54 is touched, a language selection window 92 is displayed as shown in FIG. 8, and the selected language can be changed. it can. Since Japanese is selected here, this display screen is written in Japanese.

  In the combination weight display area 55, the combination status such as the combination weight is displayed. In the speed display area 56, a graph showing the actual operation speed and the change with time of the actual operation speed is displayed. In the vibrator display area 57, the strength (value corresponding to the vibration amplitude) of the dispersion feeder 11 and the straight feeder 12 having the vibrator is displayed, and these strengths can be changed. MVF indicates a distributed feeder 11, and LVF indicates a linear feeder 12. By touching the screen shift touch key 58, other hidden display areas can be displayed.

  When the operator touches the operation start touch key 59, the operation of the combination weigher is started, and when the operator touches the operation stop touch key 60, the operation is stopped. Of these, the operation start touch key 59 is displayed larger when the operation is stopped, and the operation stop touch key 60 is displayed larger during the operation.

  The menu display area 61a includes a “zero adjustment” screen call touch key 62, a “check” screen call touch key 63, a “cleaning” screen call touch key 64, a “troubleshooting” screen call touch key 65, and a “system” screen call. Touch keys 66 are displayed, and the corresponding screen can be called by touching these touch keys. Further, when the menu switching touch key 61 is touched, the menu display area 61a is switched to display of a touch key for calling another screen.

  When the menu switching touch key 61 is touched twice, for example, on the screen of FIG. 3, the display of the touch key 61 is switched from the menu 1 to the menu 3 as shown in FIG. 4, and the “circular display” is displayed in the menu display area 61a. A screen call touch key 71, a “history display” screen call touch key 72, a “total” screen call touch key 73, a “camera” screen call touch key 74, and a “setting” screen call touch key 75 are displayed. The

  Here, when the operator touches the “setting” screen call touch key 75, as shown in FIG. 5, an operation condition setting screen 76 on which the value of the operation condition setting item can be input and changed is displayed. A basic item setting screen 82 is selected and displayed on the first setting screen 76 when it is called. On this basic item setting screen 82, setting values of basic items such as target weight and speed (operation speed) can be input and changed. When the “supply” screen calling touch key 78 is touched, instead of the basic item setting screen 82, a screen that allows input and change of setting values of items related to supply such as the distributed feeder 11 and the linear feeder 12 is called. . Similarly, when the “weighing” screen calling touch key 79 is touched, a screen that allows input and change of setting values of items related to weighing, such as the opening / closing time of the discharge gates of the supply hopper 13 and the weighing hopper 14, is called. Touching the “Discharge” screen call touch key 80, a screen on which setting values of items related to discharge such as a delay time for defining the output timing of the discharge completion signal to be output to the packaging machine can be input and changed Is called. Each setting value display area (for example, the “speed” setting value display area 94 of the basic item setting screen 82) on the screen on which these setting values can be input and changed is a touch key (setting value selection means). For example, it is touched when changing the set value.

  When the operator touches the “save” touch key 81, the changed setting value is stored in the storage unit 28. That is, the value of the operating condition setting item to be changed in the operating condition storage area of the storage unit 28 is changed (rewritten) to a value to be changed. When the “return” touch key 85 is touched, the changed setting value returns to the value before the change. Further, the control unit 21 stores a history of setting value changes, and when a “setting value history” touch key 84 is touched, a screen displaying the history of setting value changes can be called. When the “print” touch key 86 is touched, the setting value can be printed by the printing device 25. When the “return” touch key 87 is touched, the screen returns to the original screen (for example, the screen of FIG. 4) that called the setting screen 76. By touching the screen shift touch key 83, the basic item setting screen 82 can be shifted up and down to display hidden setting items.

  In this embodiment, when a set value (operation condition set value) is input and changed, the input number is uttered from the speaker 31 by voice.

  For example, when the area 94 displaying the setting value of the setting item “speed” in the basic item setting screen 82 of FIG. 5 is touched, a small numeric keypad window 88 is displayed as shown in FIG. When the operator inputs a desired numerical value using the numeric keys “0” to “9” and the decimal point symbol (period) key “.” Of the numeric keypad small window 88, the numerical value is displayed in the input display area 88a. . The “CLR” key is for erasing all the input numbers, the “DEL” key is for erasing the number just before the input, and “−” is “−” as displayed. Is to do. The “ENT” key is for confirming the input numerical value. The “ESC” key is for exiting from the small numeric keypad window 88. When touched, the small numeric keypad window 88 is closed. The numeric keys “0” to “9” and the decimal symbol key “.” Of the numeric keypad small window 88 are numerical value input means, and the “ENT” key is a numerical value determination operation means.

  When the operator inputs a desired numerical value using the numeric keys of the numeric keypad small window 88 and touches the “ENT” key, the numeric keypad small window 88 is closed and the “speed” display area 94 (FIG. 5) is displayed. The entered numerical value is displayed. At this time, it is displayed in a different display state (for example, italic letters) from the numerical values in the numerical display areas of the other setting items. When the “save” touch key 81 as the change determination operation means is touched, the control unit 21 changes the value of the setting item to be changed in the operation condition storage area of the storage unit 28 to the above-described input numerical value. Change (rewrite).

  Further, after the value of a certain setting item is changed, when the operator touches the “print” touch key 86 and the information displayed on the basic item setting screen 82 is printed by the printer 25, the basic item setting screen 82 is displayed. As with the display, the value of the changed setting item is printed in a different display state (for example, italic, bold, a color different from the value of the other setting item, or the reverse display state) from the other setting item values. Is done.

  In the present embodiment, when inputting the above-described numerical values, the numeric keys “0”, “1”, “2”, “3”, “4”, “5”, “6”, When “7”, “8”, “9” are touched, “Ray”, “Ichi”, “Nii”,..., “Hachi”, “Cue” are touched each time they are touched. The read numbers are read out individually (sounded from the speaker 31). When the decimal symbol key “.” Is touched, “ten” is read out (sounded from the speaker 31). Then, when a desired numerical value is input and the “ENT” key is touched, one number, a plurality of numbers, or a plurality of numbers and a decimal point symbol input so far are determined as a numerical value, The numerical value is read out (sounded from the speaker 31). For example, as shown in the input display area 88a of FIG. 6, when the numeric keys are touched in the order of “1”, “2”, “0”, “ichi”, “ny”, “ray” and speaker When the “ENT” key is touched, “Hyakuniju” is pronounced from the speaker 31.

  Here, for example, when a numeric key and a decimal symbol key in the numeric keypad small window 88 are touched, a signal corresponding to each key is sent from the operation input unit 23 of the operation display 22 to the control unit 21 each time the key is touched. Is input. Then, the control unit 21 outputs a control signal corresponding to the touched numeric key or decimal point symbol key to the voice synthesis LSI 29, so that the voice synthesis LSI 29 reads voice data corresponding to the control signal from the voice data memory 30. Then, it is converted into an analog signal, amplified and output to the speaker 31. As a result, the number indicated by the key touched from the speaker 31 and how to read the decimal point are output by voice. Furthermore, when the “ENT” key is touched and a corresponding signal is input from the operation input unit 23 of the operation display 22 to the control unit 21, the control unit 21 inputs the number by the numeric key and decimal symbol key so far. The voice synthesis LSI 29 recognizes the voice data corresponding to the control signal from the voice data memory 30 by recognizing the number or the numeral and the decimal point as a numeric value and outputting a control signal corresponding to the numeric value to the voice synthesis LSI 29. It is read out, converted into an analog signal, amplified and output to the speaker 31. Thereby, the reading of the numerical value is output from the speaker 31 by voice.

  FIG. 7 shows an example of a display screen when the totaling screen 89 is called by touching the “totaling” screen calling touch key 73 on the screen of FIG. 4 after driving with the speed set value changed to “120”. Show.

  In this tabulation screen 89, items other than the target weight, the upper limit value, the lower limit value, and the nominal speed are predetermined tabulation items, and the control unit 21 is configured to be able to calculate each value of these tabulation items. Yes. Note that the “nominal speed” in the aggregation screen 89 is the “speed” set on the screens of FIGS. 5 and 6, for example.

  In the control unit 21, when the “total” screen calling touch key 73 is touched, every time the driving condition is changed (setting value is changed), and when the driving ends, the same immediately before that. The value of each tabulation item during the period of driving under the driving conditions (tabulation period) is calculated, and these tabulated data are stored in the storage unit 28.

  In this tabulation screen 89, in the tabulation period for calculating the tabulation data displayed on the current tabulation screen 89 (current tabulation period) and the previous tabulation period (previous tabulation period), nominal The speed (speed) is displayed in a display state (for example, italic letters) different from other set values such as the target weight in order to indicate that the set value has been changed. In addition, the “average weight”, “standard deviation”, “maximum value”, and “minimum value” of the aggregation items are predetermined as aggregation items to be noted in connection with the speed setting value change, and their values are These are displayed in a display state different from other tabulated items, here in a state similar to the “nominal speed” (for example, italic letters). “Average weight”, “standard deviation”, “maximum value”, and “minimum value” are an average value, a standard deviation, a maximum value, and a minimum value, respectively, of the combination weights corresponding to the discharge combinations within the counting period.

  In the operating condition setting screen 76 (see FIG. 5) and the totaling screen 89, the changed setting value is displayed in italic letters so that the changed setting value is displayed differently from the other setting values. Instead, a flushing display may be displayed, or a bold display may be used. Alternatively, it may be displayed in a different color from other set values, or the background color and the numerical value color may be displayed opposite to other set values (inverted display). . Thus, by displaying the changed set value in a display state different from other set values, it is possible to easily confirm which operating condition set value has been changed.

  Further, in the same manner as in the case of the changed set value described above, on the total screen 89, the value of the total item previously determined as the total item to be noticed in relation to the changed set value is changed to other total items. The value and display state are made different. This makes it easier for the operator to check the value of the summary item related to the changed setting value, and thus makes it easier to determine whether the setting value has been changed.

  The “print” touch key 90 is a touch key for printing. When the touch key 90 is touched, information displayed on the total screen 89 is printed by the printing device 25. Also in this case, similarly to the display on the total screen 89, the numerical value of the changed setting item and the display state in which the value of the total item to be noted in connection with the change is different from the values of the other total items (for example, italic characters). , Bold, a color different from other values, or a reverse display state).

  The “Home” touch key 91 is a touch key for returning to the screen on which the counting screen 89 is called. When the touch key 91 is touched, for example, the screen returns to the screen of FIG.

  Next, a language switching method will be described.

  For example, when the operator touches the language switching touch key 54 on the display screen of FIG. 3, a language selection window 92 is displayed as shown in FIG. Here, each language area displayed in the language selection window 92 is a touch key 93 (language selection means). Each time these touch keys 93 are touched, the state of characters indicating the language displayed on the touch key 93 is switched between a reverse display state and a non-reverse display state (normal state), and the reverse display state is selected. Indicates that In FIG. 8, since Japanese is selected, the Japanese touch key 93 is displayed in a reverse display state (indicated by hatching in FIG. 8).

  When the operator touches the language switching touch key 54 after selecting any language by touching the touch key 93, the selected language is set and the language selection window 92 is closed. The language (character) in the screen displayed on the screen 22S and the language of the sound generated from the speaker 31 are determined by the language set here.

  It is also possible to select a plurality of languages by touching the touch key 93. In this case, the language selected first is determined as the language (character) in the screen displayed on the screen 22S. The language of the sound generated from the speaker 31 is determined as a plurality of selected languages, and is output from the speaker 31 in the order selected by the touch key 93, for example. For example, when the selection is made using the touch key 93 in the order of “English” and “Japanese”, the language (characters) in the screen displayed on the screen 22S is written in English. In addition, the speaker 31 emits Japanese after English. For example, when the number key “1” in the small numeric keypad window 88 of FIG. 6 is touched, “one” is uttered in English from the speaker 31 and then “ichi” is uttered in Japanese.

  In the present embodiment, when the operator changes the operating condition of the device, every time one of a number and a decimal point symbol is input, the reading is output from the speaker 31 by voice. As a result, the operator can listen to and confirm the numbers to be entered one by one, thereby preventing erroneous input of the operating condition set value and setting an unintended value as the operating condition set value. Can be prevented. Furthermore, when an operation for confirming the input number or the like as a numerical value is performed, how to read the numerical value is output by voice from the speaker 31, so that the input numerical value can be heard and confirmed by ear, It is possible to further prevent erroneous input of operating condition set values.

  If a plurality of languages are selected, how to read the input numbers and how to read the determined numerical values are output from the speaker 31 in a plurality of selected languages, so that there are a plurality of operators. This is useful when a person from multiple countries becomes an operator.

  Moreover, although the speaker 31 is provided as an audio | voice output means, it is not restricted to this, For example, an earphone etc. may be provided.

  In the above embodiment, a combination weigher has been described as an example of the device. However, the present invention is not limited to this. The present invention can be applied to an operation control device for equipment that is operated by changing the operation condition set value. The effect is particularly great when applied to an operation control device of a weighing instrument such as a combination weigher or a weight type sorter in which the operating condition set value is frequently changed.

  INDUSTRIAL APPLICABILITY The present invention is useful as an operation control device that can prevent an erroneous input of an operation condition set value when an operator changes an operation condition of an apparatus.
