  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.

<1. Embodiment>
FIG. 1 is a schematic view showing a combination weighing device 1 according to the present invention. FIG. 2 is a block diagram showing the configuration of the combination weighing device 1. The combination weighing device 1 mainly includes a main body unit 2 and a control unit 3. In addition, although illustration is abbreviate | omitted in FIG. 1, the main-body part 2 of the combination weighing | measuring device 1 is supported by the housing | casing. The control unit 3 is attached to the housing and is connected to the main body unit 2 in a state where data communication is possible.

  The main body 2 includes a dispersion feeder 20, a plurality of troughs 21, a plurality of pool hoppers 22, a plurality of weighing hoppers 23, a plurality of weighing units 24 and a discharge chute 25. In FIG. 1, two troughs 21, a pool hopper 22, a weighing hopper 23, and a weighing unit 24 are all illustrated, but more of these configurations are usually provided.

  Although details are not shown, the dispersion feeder 20 includes a conical vibration part and a drive part that vibrates the vibration part, and has a function of dispersing the articles supplied to the combination weighing device 1 into a plurality of troughs 21. Have. That is, the articles supplied near the top of the vibration part of the dispersion feeder 20 are dispersed while moving toward the periphery so as to slide down the slope of the vibration part, and each trough 21 arranged so as to surround the periphery of the vibration part. It is discharged toward

  As described above, each trough 21 is radially arranged so as to surround the periphery of the dispersion feeder 20, and each of the troughs 21 linearly conveys the articles carried from the dispersion feeder 20 in the horizontal direction by the conveyance vibration. . Articles conveyed by each trough 21 are put into a pool hopper 22 provided corresponding to each trough 21.

  Each pool hopper 22 includes a housing that temporarily stores the articles that have been thrown therein, and a gate that opens and closes in response to a control signal from the control unit 3. Each pool hopper 22 temporarily stores the articles input from the trough 21 and opens the gate in response to an open signal from the control unit 3 to input the stored articles to the corresponding weighing hopper 23. .

  Each weighing hopper 23 includes a housing that temporarily stores an article that has been thrown therein, and a gate that opens and closes in response to a control signal from the control unit 3. Each weighing hopper 23 temporarily stores the articles input from the pool hopper 22 inside, and opens the gate in response to an open signal from the control unit 3 to input the stored articles into the discharge chute 25.

  Each weighing unit 24 is provided for each weighing hopper 23, and obtains a measured value by weighing (measuring) the weight of an article stored in the corresponding weighing hopper 23. In other words, in the combination weighing device 1, articles are weighed for each amount stored in the weighing hopper 23. In addition, each measured value acquired by each measuring unit 24 is transmitted to the control unit 3.

  The discharge chute 25 is combined by assembling articles input from the weighing hopper 23, and then intermittently discharged to the outside every predetermined cycle. The articles discharged from the discharge chute 25 are put into, for example, a packaging machine (not shown) arranged downstream of the combination weighing device 1.

  As shown in FIG. 2, the control unit 3 includes a CPU 30 that calculates various data, a storage unit 31 that stores various data, an operation unit 32 that includes buttons, switches, a pointing device, and the like, and a touch panel 33. It has a function as a general computer.

  The control data 310 is data storing individual operating conditions of the combination weighing device 1. The control data 310 in the present embodiment is data of a table structure in which one record is created for each operation condition, and each record has one condition identifier indicating one operation condition, and the condition The conditions (setting values) set for the operating conditions indicated by the identifier are stored.

  Then, the control data 310 is referred to by the CPU 30 as necessary when each component of the combination weighing device 1 is controlled. For example, when the set value of the operating condition “stable time” is set to “400 msec”, the CPU 30 waits for 400 msec after the article is put into the weighing hopper 23 and then put into the weighing hopper 23. The weighing unit 24 is weighed by the weighing unit 24. When the operation of the combination weighing device 1 is started, initial values for the operation conditions are set and stored in each record of the control data 310. These operating conditions can be set (changed) by an operator (details will be described later).

  In the order data 311, key identifiers for identifying individual setting keys are stored in accordance with the display order. Although details will be described later, the rank of each key identifier in the order data 311 indicates the arrangement position (display position) of the setting key indicated by the key identifier on the touch panel 33.

  The touch panel 33 has a function of displaying various data as images on the screen. In particular, the touch panel 33 in the present embodiment displays a plurality of setting keys for setting individual operation conditions included in the operation conditions of the combination weighing device 1.

  The touch panel 33 has a function of detecting the position on the touched screen and transmitting it to the CPU 30 when an operator (or a touch pen or the like) touches the screen. In other words, it has a function of accepting an operator's operation on a plurality of setting keys displayed on the screen.

  FIG. 3 is a diagram illustrating functional blocks included in the control unit 3 together with a data flow. The display control unit 300 and the change unit 301 illustrated in FIG. 3 are functional blocks that are realized mainly by the CPU 30 operating according to a program.

  4 to 6 are diagrams illustrating an operation screen 330 displayed on the touch panel 33 by the display control unit 300. FIG.

  The operation screen 330 configured as a GUI screen is a screen displayed by the display control unit 300 as described above, and is provided with the display window 4 and the scroll bar 5. The display window 4 is an area for displaying the setting key arrangement image 40. The scroll bar 5 has a function of scrolling the setting key arrangement image 40 displayed on the display window 4.

  The display control unit 300 refers to the order data 311 and reads the key identifiers stored in the order data 311 according to the order stored in the order data 311. Then, on the setting key arrangement image 40, an image associated with the read key identifier (an image representing each setting key 6) is arranged at an arrangement position corresponding to the order read from the order data 311.

  In the present embodiment, the setting key 6 indicated by the read key identifier is arranged at a position adjacent to the order display button 7 corresponding to the read order. In the example shown in FIG. 4, since the setting key 6a is arranged adjacent to the order display button 7 displaying “01”, the setting key 6a is “1st” in the order data 311. I understand that. Similarly, the order displayed on the order display button 7 is ascending order in the setting key arrangement image 40, and the setting key 6 with the earlier order in the order data 311 is displayed first in the setting key arrangement image 40. I understand that

  In the combination weighing device 1 in the present embodiment, the display position of the setting key arrangement image 40 on the touch panel 33 is fixed by the display window 4. Therefore, determining the arrangement position of each setting key 6 in the setting key arrangement image 40 corresponds to determining the arrangement position (display position) of each setting key 6 (6a to 6u) on the touch panel 33.

  Each setting key 6 displays a name of an operating condition that can be set by operating the setting key 6. For example, “product image” is displayed on the setting key 6a shown in FIG. Therefore, by confirming this, the operator can easily recognize that the setting key 6a is the setting key 6 operated to select and set the product image (article image).

  In addition, each setting key 6 in the present embodiment has a different shape and configuration depending on operating conditions that can be set by operating the setting key 6. For example, the setting key 6a shown in FIG. 4 is provided with an area for displaying a product image, and therefore has a relatively large size compared to the other setting keys 6. A pull-down button for displaying a list is provided. A setting key 6j shown in FIG. 5 is a setting key 6 that is operated to alternatively set whether or not the average value control is necessary. , A round button corresponding to the average value control “Yes” is provided, and any one of the round buttons is operated.

  In the storage unit 31, the key identifier of each setting key 6, the condition identifier of the operating condition that can be set by operating the setting key 6, the name of the operating condition, and the setting key 6 Correspondence data (not shown) that associates the images with each other is created and stored. The display control unit 300 appropriately refers to the correspondence data when displaying the operation screen 330.

  For example, the display control unit 300 searches the corresponding data with the key identifier acquired from the sequence data 311 and acquires the name and image of the operating condition associated with the key identifier. Then, after synthesizing the acquired operation condition name with the acquired image, the setting key 6 indicated by the key identifier is set to a predetermined position of the setting key arrangement image (a position determined according to the order acquired from the order data 311). ).

  At this time, the display control unit 300 acquires a condition identifier associated with the key identifier from the corresponding data as necessary. Then, the control data 310 is searched with the acquired condition identifier, the current set value of the operation condition is acquired and displayed on the setting key 6. For example, the setting key 6e (target weight value setting key) shown in FIG. 4 displays characters of the setting value “100g” acquired from the control data 310 in this way. As a result, the operator can easily confirm the current set value, and can easily determine whether or not it is necessary to operate.

  In the combination weighing device 1 according to the present embodiment, it is necessary to set a large number of operating conditions. Therefore, it is necessary to display a large number of setting keys 6 (setting keys 6a to 6u in the present embodiment) on the touch panel 33. Therefore, the size of the setting key arrangement image 40 on the touch panel 33 is considerably larger than the size of the display window 4 on the touch panel 33. For this reason, in the present embodiment, the setting key arrangement image 40 is scrolled by the scroll bar 5 so that the entire area of the setting key arrangement image 40 can be displayed sequentially and continuously.

  The area of the setting key arrangement image 40 displayed when the scroll bar 5 is in the initial state (position shown in FIG. 4) is referred to as “initial display area”. That is, the initial display area is an area that is displayed first when the display control unit 300 switches the screen of the touch panel 33 to the operation screen 330.

  In addition, the display control unit 300 displays the setting key 6 whose rank in the order data 311 is lower than the reference rank (10th rank in the present embodiment) smaller than the setting key 6 that is equal to or higher than the reference rank. Therefore, as shown in FIG. 5, in the operation screen 330, the eleventh and subsequent setting keys 6 are displayed in a reduced size as compared to the tenth setting key 6. Thereby, the operator can easily recognize that the operation frequency of the eleventh and subsequent setting keys 6 is low.

  Further, the plurality of setting keys 6 include a target weight value setting key (setting key 6e: FIG. 4) for setting a target weight value as an operation condition, and the target weight value setting key is set higher in the sequence data 311. In the example shown in FIG. 4, the setting key 6e is set to “fifth place” and is displayed in the initial display area. The target weight value is a weight value of an article (product) to be obtained by combining the weighing values by the combination weighing device 1, and is a target value for combining the articles. In the combination weighing device 1 in the present embodiment, the operator's attention is set by setting the display order of the setting key 6e for setting the target weight value, which is an important operating condition specialized for the combination weighing device 1, to the upper level. Can be particularly aroused.

  Returning to FIG. 3, the changing unit 301 changes the order data 311 stored in the storage unit 31 according to the operation of the operator. The “operator operation” referred to here includes not only an operation on the touch panel 33 but also an operation on the operation unit 32. That is, the change unit 301 in the present embodiment detects an operator operation on the operation unit 32 or the touch panel 33 and changes the display order indicated in the order data 311 according to the operation.

  FIG. 7 is a diagram illustrating an operation screen 331 that is displayed after an operation by the operator is performed on the operation screen 330 illustrated in FIG. 5. FIG. 7 shows a state in which the setting key 6k displayed on the operation screen 330 shown in FIG. 5 is operated and the setting value of the operating condition “priority participation frequency” is changed from “30” to “25”.

  In the example shown here, the display of the setting key 6j and the setting key 6k is displayed because the operator operates the setting key 6k and the changing unit 301 moves up the rank in the order data 311 from “11th” to “10th”. The position has changed. In the present embodiment, as described above, since the reference rank is set to “10th place”, the setting key 6k raised to “10th place” is displayed without being reduced, The setting key 6j lowered to “11th place” is reduced and displayed.

  In this way, by changing the order data 311 so that the order of the setting key 6 in the order data 311 is increased by the operation of the setting key 6 by the operator, the operation screen 330 can be displayed only by the operator performing a normal setting operation. Customized automatically. In particular, by moving up the order of the operated setting key 6, the higher the setting frequency of the setting key 6, the higher the order, and the display position on the touch panel 33 comes first. Therefore, since the setting key 6 with higher use frequency is displayed first, the convenience for the operator is improved.

  In addition, you may change so that the order | rank in the order data 311 of the operated setting key 6 may be lowered | hung. For example, when the setting key 6 is double-clicked, the order of the setting key 6 may be changed. Thereby, for example, when the order is changed by accidentally touching the setting key 6, the original position can be restored.

  In the combination weighing device 1 according to the present embodiment, the operator inputs a new rank (numerical value) in the input field displayed by operating the order display button 7, so that it is adjacent to the operated order display button 7. It is also possible to change the order of the setting keys 6 displayed in this way to a new order. That is, it is possible not only to change the order data 311 indirectly by an operation for setting / changing the operating conditions, but also to change the order data 311 directly.

  Further, the order data 311 may be changed according to the operation order of the setting keys 6 by the operator. That is, when all the processes for changing the operating condition are completed, the setting data 611 operated so far and the order data 311 may be changed according to the operation order. Thereby, since the setting key 6 is displayed on the touch panel 33 according to an operator's favorite operation order from the next time, the convenience for the operator is improved.

  In the present embodiment, the setting key 6j shown in FIG. 5 is changed only by operating one of the round buttons, and the operating condition (presence / absence of average value control) corresponding to the setting key 6j in the control data 310 is changed. The On the other hand, by operating the setting key 6, for example, an input field is displayed, and a character is input to the input field from the operation unit 32, thereby changing the set value of the operation condition of the control data 310. Sometimes it is done. That is, a plurality of setting keys 6 displayed on the touch panel 33 are operated by an operator to set individual operating conditions, but “operated to set operating conditions” means that the setting keys 6 are It is not limited to the setting key 6 that can complete the setting of the corresponding operation condition only by operating.

  As described above, the combination weighing device 1 includes a plurality of setting keys 6 operated by an operator to set individual operation conditions in the present device, a touch panel 33 that displays the plurality of setting keys 6, and a plurality of settings. The storage unit 31 that stores the individual display order of the keys 6 as the order data 311 and the touch panel by determining the arrangement positions of the plurality of setting keys 6 according to the display order shown in the order data 311 stored in the storage unit 31 The display control unit 300 that displays a plurality of setting keys 6 on the display 33 and the change unit 301 that changes the display order indicated by the order data 311 stored in the storage unit 31 according to the operation of the operator are provided. The arrangement of the setting keys 6 on the touch panel 33 is changed according to the operation of the touch panel 33. It can, thereby improving convenience.

<2. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made.

  For example, the functional blocks included in the combination weighing device 1 have been described as being realized by the CPU 30 operating according to the program. However, some or all of the functions of these functional blocks may be realized by a dedicated logic circuit. .

  Further, in the above-described embodiment, the setting key 6 whose rank in the order data 311 is lower than the reference rank is displayed to be reduced to be smaller than the setting key 6 that is higher than the reference rank. However, the display control unit 300 causes the setting keys 6 that are not arranged in the initial display area of the touch panel 33 among the plurality of setting keys 6 to be displayed with a smaller size than the setting keys 6 arranged in the initial display area. You may comprise. Also with this configuration, it is possible to easily notify the operator that the setting key 6 displayed in a reduced size has a low operation frequency.

  Further, the display control unit 300 may display the setting key 6 whose rank in the order data 311 is lower than the reference rank as the setting key 6 that is not arranged in the initial display area of the touch panel 33. Thereby, since the setting key 6 with low operation frequency is excluded from the initial display area, it is possible to easily confirm the target setting key and to suppress erroneous operation of the setting key 6 other than the target.

  Of the plurality of setting keys 6, the setting keys 6 in the order of the setting key 6 designated by the operator may be displayed as setting keys 6 that are not arranged in the initial display area of the touch panel.

  In the above embodiment, the setting key arrangement image 40 is continuously scrolled by the scroll bar 5 in the display window 4. However, the entire area of the setting key arrangement image 40 having a size larger than that of the display window 4 is touched. The method of displaying on 33 is not limited to this. For example, the setting key arrangement image 40 is divided into three page images, and the first page image of the three images is displayed when the operation screen is displayed for the first time. Then, when the operator gives an instruction to turn the page, it may be configured to sequentially switch to the next page image.
