FIELD OF THE INVENTION The present invention relates to a weighing device for weighing articles.

[0002]

2. Description of the Related Art Among weighing devices, a weighing device for weighing a plurality of types of articles requires work for setting operating conditions corresponding to the articles.

For example, in the case of a conveyor type weighing device which weighs an article while it is being conveyed by a conveyor and judges the quality of the article based on the weight, the item is weighed after it has been carried into the weighing conveyor. Since the measurement is performed, it is necessary to set the article length and the transportation speed as the weighing conditions. In addition, the value that is the basis of the weight determination is also necessary as the weighing condition. further,
Processing parameters for performing statistical processing based on weighing results, determination results, and the like, conditions for determining the display mode of the weighing results and determination results during operation, and the like may be set depending on the article.

In the conventional weighing device which requires a setting operation for many setting items in order to determine the operating conditions, these setting items are displayed in a predetermined order on the display unit of the weighing device. Then, the setting value and the like are input from the operation unit, and the operation is started after all the setting operations are completed.

[0005]

However, there are various types of usage of this kind of weighing device, and for example, in a factory that weighs only varieties of the same shape, the set value is changed when the varieties are switched. Although there are few changes, on the display screen, screens that do not need to be changed are sequentially displayed, which is annoying.

For this reason, if a weighing device having only a limited setting function is manufactured as a dedicated machine for each user, the burden on the weighing device maker side will be very heavy. It is an object of the present invention to solve this problem and provide a weighing device that allows each user to match his or her own usage pattern.

[0007]

In order to solve the above-mentioned problems, a weighing device of the present invention has a weighing unit for weighing articles, an operating unit, and a weighing result by the weighing unit. In order to preset the operating conditions including the display unit and the weighing conditions necessary for the weighing operation of the weighing unit and the display format of the display unit during the weighing operation, the setting screen is displayed on the display unit, and In a weighing device having an operating condition setting means for setting operating conditions on the weighing unit and the display unit in response to a setting operation by an operation unit, item names of a plurality of setting items that determine the operating conditions and setting screen information thereof are displayed. When the setting item storage unit stored in advance and the operation unit receive a specific operation, each setting item name of the setting item storage unit is displayed on the display unit, and the setting item of each displayed setting item is set. Before or after A setting item designating unit for designating by operating the operating unit and an operation definition parameter storage unit for storing information corresponding to the presence or absence of each setting item designated by the setting item designating unit as an operation definition parameter are provided, and the operation is performed. The condition setting means refers to the operation definition parameter stored in the operation definition parameter storage means, displays a setting screen for the setting item designated as having a setting operation on the display unit, and displays the displayed setting. The operating conditions input by the operation unit on the screen are set in the measuring unit.

[0008]

With this configuration, in the weighing device of the present invention, the information corresponding to the presence / absence of the setting item designated by the setting item designating means by the user is stored as the operation definition parameter, and when the operating condition is set, this operation definition is set. The operation screen for the setting item corresponding to the parameter is displayed.
The operating conditions can be set in the metering unit and the display unit only by inputting a set value or the like for the setting item displayed on the screen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of a weighing device 10 according to an embodiment. The weighing device 10 receives the article W carried in from the carry-in conveyor 1 into the run-up conveyor 11 and carries the article W from the run-up conveyor 11 to the weighing conveyor 12.

The weighing conveyor 12 is supported by a weighing device 13, and a weighing signal corresponding to the weight of the article carried into the weighing conveyor 12 is output from the weighing device 13 to the measuring section 14.

The measuring section 14 receives the weighing signal from the weighing machine 13, detects the weight of the loaded article after the article is carried into the weighing conveyor 12, and outputs the detected weight value to the determining section 15.

The determination unit 15 determines whether the weight value from the measurement unit 14 is within a preset allowable range and outputs a determination signal according to the determination result.

In this way, the articles that have undergone the weighing determination are carried out from the weighing conveyor 12 to the sorting line 2 and sorted according to the determination signal from the determination unit 15.

The determination signal from the determination unit 15 is input to the display control unit 16 together with the weight value. The display control unit 16 uses the preset operation display format to display the display 17
Display the judgment result and weight value on.

The transport controller 18 drives the run-up conveyor 11 and the weighing conveyor 12 at a preset conveyor speed.

The measuring unit 14, the determining unit 15, and the transport control unit 18 described above constitute the weighing unit of this embodiment, and the display control unit 16 and the display unit 17 are the display units of this embodiment. Make up.

The operation unit 19 is provided on the operation surface (not shown) of the weighing device together with the display 17, and turns on / off the power of the weighing device 10 and starts / stops the weighing operation.
It has a plurality of keys (not shown) for inputting set values and changing modes. The mode switching means 20 switches the mode of the weighing device to an operation mode, a setting mode for setting operating conditions, and an operation definition mode for defining the operation of the setting mode, by operating a key on the operation unit 19.

The setting item storage means 21 stores in advance information about setting items to be set on the screen by the weighing device according to the articles.

In the operation definition mode, the setting item designating means 22 causes the display device 17 to display the setting item names stored in the setting item storing means 21, and to designate the presence or absence of them, for example, designated as present. Data of 1 is assigned to the item and data of 0 is assigned to the item designated, and the series of data consisting of 0 and 1 is stored in the operation definition parameter storage means 23 as the operation definition parameter.

In the setting mode, the operating condition setting means 24 refers to the definition parameters stored in the operation definition parameter storage means 23, and displays the screen information on the setting item designated as "present" in the operation definition mode. When the settings are confirmed by accepting the input of each set value from the operation unit 19, the set values input for each set item are displayed on the measuring unit 14, the determination unit 15, and the display unit 17. The control unit 16 or the like is set.

FIG. 2 shows a processing procedure of the weighing device 10. The operation of the weighing device 10 will be described below based on this flowchart. When the weighing device 10 is powered on, the display 17 displays the reference value (100.0), the upper and lower limit values (± 10.0), and the like of the previous operation, as shown in FIG. 3, for example. An instruction to operate the "drive key" to start the operation as it is and to operate the "set key" to change the set value is displayed as an initial screen (S
1).

When a specific key operation (for example, input operation of a password registered in advance) is performed in this initial state, the weighing device 10 shifts to the operation definition mode, and the setting item information is partially stored from the setting item storage means 21. For example, as shown in FIG. 4A, the name of each setting item and the display of the presence / absence of the setting operation are read and displayed on the display screen of the display unit 17 (S).
2, 3). Since "reference value setting" in FIG. 4A is designated as "present", a screen for performing the reference value setting operation is displayed in the setting mode.
Further, since "none" is designated as the "item name display", the item name of the item being weighed is not displayed on the display 17 in the operation mode.

Here, regarding an article that may be weighed by the user, for example, assuming that it is not necessary to set the upper limit value, the operation of the operation unit 19 causes the "upper limit value setting" as shown in FIG. When the operation of changing the designation of “present” of “to” is set to “absent”, the operation definition parameter corresponding to this setting item is changed to 0 (S4, 5).

In this way, when the screen is switched by the operation of the operation unit 19 after the operation of designating the setting items for one screen is completed, a plurality of other setting items are displayed.
Similarly, a setting item stored in the setting item storage means 21 is called and its designation is changed on the display screen. (S6, 7).

In this way, when the selection and designation of the setting item suitable for the usage pattern of the user is performed, the display screen returns to the initial state.

Next, when the weighing device 10 is switched to the setting mode by operating the operation unit 19, each setting screen for the setting items corresponding to the parameters stored in the operation definition parameter storage means 23 is sequentially displayed. 17 is displayed, and the operation of inputting a numerical value or selecting a preset value for each setting item is accepted (S8 to 13).

FIG. 5 shows an example of the reference value setting screen. The operation method is displayed in the upper part of the screen and the lower part is displayed in the lower part.
The previously stored reference value (100.0) and lower limit value (-10.0) are displayed, and the reference value is designated by the cursor. Then, after inputting a new reference value according to the displayed operation method, the next setting item "Lower limit value setting"
Switch to the setting screen of, and similarly set the necessary setting values on the operation unit 1.
Input from 9. If it is not necessary to change the set value, the operation to move to the next screen is performed.

Here, since the "upper limit value setting" is designated as "absent" in the above-mentioned operation definition mode, the setting screen for "upper limit value setting" is omitted after "lower limit value setting", and another screen is displayed. Perform the setting operation for the setting items of.

When the setting operation for each setting item is performed in this manner, these setting values are set as the operating conditions of the weighing device 10 by the measuring unit 14, the determining unit 15, the display control unit 16, the transport control. It is set in each of the parts 18 and the like, and then returns to the initial state. The initial screen displayed at this time displays the set value changed in the setting mode.

Although not shown in this flowchart, if the operating conditions (measurement conditions and display format) for each product type are stored in advance in the operating condition setting means, the operating conditions for the required product type are read out. Then, the settings may be collectively set in the weighing unit, the display unit, or the like.

Here, when the weighing device 10 is switched to the operation mode by the operation of the operation unit 19, the operation of the weighing device 10 is started under the operating condition set by the setting mode, and the operation is continued until the stop operation is performed. Continue (S
14-16).

That is, the run-up conveyor 11 and the measuring conveyor 1
2 is driven at a set conveyor speed, and the articles carried in from the carry-in conveyor 1 are carried in to the weighing conveyor 12 via the run-up conveyor 11, and from the carry-in, the predetermined article length, conveyor speed, etc. are determined. When the time passes and the article is completely carried into the weighing conveyor, the weighing unit 13 measures the weight of the article by the weighing signal from the weighing machine 13.
Detected in. This weight is input to the determination unit 15 and the display control unit 16, and it is determined whether or not the weight is within the allowable range determined by the set reference value and the lower limit value.
The determination result is sent to the display control unit 16 and the sorting line 2.

The display device 17 displays the operation display mode set in the setting mode by switching to the operation mode, for example, as shown in FIG. 6, the reference value (102.5) and the lower limit value (-10. 0) display area is provided, and a bar graph display area for the weight with the reference value and the lower limit value as a scale is provided on the display area.
And a display area for displaying the weight (101.1) of the article are provided, and the weight value detected by the measurement unit 14 and the determination result of the determination unit 15 are displayed according to this display format.

Items that have undergone the weighing determination in this way are
Along with the determination signal, it is sent to the sorting line 2 and undergoes sorting according to the determination result.

As described above, in the weighing device 10, since it is only necessary for the user to perform the setting operation for the setting item designated in advance, the display of the setting screen unnecessary for the user is eliminated, and the switching operation of the screen is eliminated. Since it is not necessary, the operation of setting operating conditions becomes very easy.
