Description

  The present invention relates to a weighing support device that performs weighing while instructing an operator of weighing contents, and a weighing system using the device.

2. Description of the Related Art Conventionally, a weighing support device has been put into practical use in which the content of weighing work is set in advance as weighing instruction information, and an operator can weigh the weight of an article according to the weighing instruction information (for example, patents) Reference 1). The procedure for measuring using such a weighing support device is generally as follows.
First, a work instruction file in which the article name of the article to be weighed and the weight value (indicating measurement value) of the article to be weighed is created in advance. As shown in FIG. 4, for example, the work instruction file is an item name A, B, C,...

When weighing an article, an operator inputs an article name of the article or selects an article from a list of article names displayed on the display screen to specify the article to be weighed. Alternatively, the instruction number of the work instruction file (the leftmost column in FIG. 4) is designated by the administrator or the management computer.
Then, the weighing support apparatus reads the work instruction file from the storage unit, and the article name and the instruction weighing value of the article specified by the operator recorded in the file are displayed on the display screen. The operator can know how much weight should be weighed by looking at the displayed indication weighing value. Further, in the case of specifying the weighing work by the instruction number, it is possible to know which article should be weighed and how much.
Japanese Patent Laid-Open No. 10-48033

By the way, the indicated measurement value described in the work instruction file is not always smaller than the value of the balance of the balance to be used for measurement (the maximum weight value that can be measured by the balance). That is, there is a case where the work instruction file is described so as to weigh articles having a weight exceeding the weight of the scale to be used.
In such a case, the operator performs multiple weighings by dividing the above weighing designated as a single weighing into several weighings at a weight value that can be weighed by the balance used. It will be. For example, if the scale used is 3 kg and the indicated weighing value is 8.5 kg, the original indication is divided into 3 weighings, 3 kg weighing twice and 2.5 kg weighing once. A measured value of 8.5 kg is weighed.

However, when dividing a single weighing into multiple times as described above, the operator must first grasp the weight of the balance to be used. You have to calculate and decide what to do. In addition, when the number of divisions is large, the operator records the number of divisions or records it on paper, and proceeds with each measurement while considering the number of divisions completed and the number of remaining measurements. It is necessary to go.
As described above, in the conventional weighing support device, when weighing a weight that is equal to or greater than the weighing value of the balance to be used, complicated incidental operations such as calculation for dividing the weighing by the operator himself and storage of the division result are performed. Therefore, there was a problem that the entire weighing operation could not be performed smoothly.

  The present invention has been made in view of this point, and an object of the present invention is to provide a weighing support device capable of smoothly performing a weighing operation even when weighing a weight that is equal to or greater than a weighing value of a balance to be used, and the device. It is to provide a weighing system using the.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a weighing support device 1 according to an embodiment of the present invention and a weighing device (balance) 2 connected to the device. As shown in the figure, a weighing system is constructed by a weighing support device 1 and a scale 2 connected to each other. A management PC (personal computer) 4 is a computer for work management and various data management.
1, the CPU 11 is a central processing unit that controls the operation of the apparatus 1 by executing a program on the ROM 12. The ROM 12 is a read-only memory that stores the program of the apparatus 1. Is a read / write memory for temporary storage of data.

The display drive circuit 16 is a circuit that converts an input signal from the CPU 11 into a signal for displaying on the display unit 17.
The display unit 17 is a character / number / image data such as a menu for operating the apparatus 1, an instruction weight value read from the work instruction file, an article name, a message to the operator, and a weight value of the article being weighed. Is a liquid crystal display that functions as notification means. Data to be displayed is input from the CPU 11 via the display drive circuit 16.

  The key input unit 18 is a touch panel for operating the apparatus 1 and is configured integrally with the liquid crystal display of the display unit 17. This touch panel is provided with numeric keys 0 to 9, a decimal point key, up / down / left / right cross keys, a determination (return) key, a menu selection key, and the like according to the operation contents at the time of operation. .

The communication I / F (interface) 19 is an interface module that is connected to the external management PC 4 to transmit and receive various data. In the present embodiment, a work instruction file is downloaded from the management PC 4 via the communication I / F 19, or a work history file in which the result of the weighing work is recorded for performing work management on the PC is uploaded. To do.
The scale connection unit 20 is an interface for connecting to an external scale.

The non-volatile memory 22 is a flash memory that stores a setting file of the apparatus 1 as well as a weighing file described later and a work instruction file downloaded from the management PC.

1 is a scale composed of a weighing pan 25, a load cell 26, an A / D conversion circuit 27, and a connection port 28.
The load cell 26 is a load sensor including a metal strain generating body and a strain gauge attached to the strain generating body. When a strain is applied to the strain generating body due to a load, the strain gauge is deformed, and the strain gauge according to the deformation amount. This is a module that takes out the amount of load as a voltage value because the resistance value changes. The weighing pan 25 is a tray on which a material to be weighed is placed. The weighing pan 25 is installed on the top of the load cell 26 so that the load from the material placed on the pan is transmitted to the load cell 26.

The A / D conversion circuit 27 is an analog-digital conversion circuit that converts the voltage value of the analog signal input from the load cell 26 into a digital signal. The converted digital data is sent to the CPU 11 via the connection port 28 and is recognized as the weight of the article placed on the weighing pan 25.
The connection port 28 is an interface for connecting to the weighing support device 1.

2 to 4 show examples of the weighing file, the division ratio file, and the work instruction file stored in the nonvolatile memory 22, respectively.
The weighing file is a weighing storage means in which several weighing values are described, and the weighing of the weighing scale to be actually used is selected from these and designated by the weighing number (the left column in FIG. 2).
The split ratio file describes split ratio options. Here, the division ratio is a parameter that determines how much of the ratio of the new indicated measurement value after dividing the measurement to the value of the weighing. For example, if the division ratio is 0.5 with respect to a weighing of 30 kg, the new indicated weighing value is 15 kg.

  The work instruction file shown in FIG. 4 is a weighing instruction information storage unit that describes weighing content instruction information including an article name of an article to be weighed and a weight value to be weighed (indicated weighing value). These article name and instruction weighing data are displayed on the display unit 17 during weighing so that the operator can clearly grasp the weighing contents.

Next, the operation of the weighing system described above will be described with reference to the flowchart shown in FIG.
First, the weighing support device 1 displays a weighing setting screen on the display unit 17 and prompts the operator to set the weighing of the balance to be used. At this time, the data of the weighing file read from the non-volatile memory 22 (“Weighing number” and “Weighing”) and “Select the weighing of the balance to be used and then press the number determination key on the weighing setting screen.” Is displayed.
Here, as described above, the display unit 17 is configured integrally with the touch panel (key input unit 18), and the numerical portion of the “weighing number” on the screen can be touched. Further, an up / down arrow key for scrolling display contents, a number determination key, and a setting completion key are also displayed on the same screen, and these keys can also be touched.

  When the operator inputs a weighing number corresponding to the scale used for weighing according to the message, the selected weighing data is written in the RAM 13 (step S1). Here, a weighing of 3 kg is selected.

  Next, the weighing setting screen is switched to set the division ratio, and the data of the division ratio file read from the non-volatile memory 22 and the message “Select the division ratio and then press the number determination key” are displayed. Is displayed. When the operator inputs the division ratio, the selected division ratio data is written in the RAM 13 (step S2). Here, it is assumed that the division ratio “1.0” is selected. It should be noted that the division ratio input here can be arbitrarily selected so that the worker suits his / her preference and convenience.

  When the above input is completed and the operator presses the setting completion key, the product of the weight value written in the RAM 13 and the division ratio (hereinafter referred to as division unit weight) is calculated, and the value is written in the RAM 13 ( Step S3). According to the above input, the division unit weight is 3 kg from the weighing amount of 3 kg and the division ratio “1.0”.

Next, a measurement setting screen is displayed on the display unit 17, and the measurement content is set by the operator. On this weighing setting screen, data of “instruction number”, “article name”, and “instruction weighing value” in the work instruction file are displayed. A message “Please select an instruction number” is also displayed.
In the following description, it is assumed that the weighing of instruction number “1” is performed. When the operator inputs the instruction number “1”, the data of the article name “A” and the instruction weighing value “8.5 kg” corresponding to the instruction number “1” is obtained from the work instruction file in the nonvolatile memory 22. It is read and written to the RAM 13 (step S4).

  Subsequently, a “temporary work instruction file” is created in the RAM 13, and the instruction measurement value (8.5 kg in the above case) is written in the first line of this file (step S5). Here, the temporary work instruction file is a work file for storing the instruction metric value relating to the measurement selected in step S4. When the measurement is divided, a new instruction after the division is performed according to the steps described later. If the measurement value is described in a plurality of lines and the measurement is not divided, only the original instruction measurement value written in step S5 remains described in the first line. As described above, the temporary work instruction file functions as a storage unit that stores the divided instruction metric values.

  Next, the CPU 11 compares the magnitude relationship between the weighing value written in the nonvolatile memory 22 in steps S1 and S4 and the indicated weighing value (step S6). If the indicated measured value is larger, the weighing cannot be performed as it is due to overweight, so step S7 is performed to divide the weighing into a plurality of times, and if the measured value is larger, the step is performed immediately. Proceed to S8 respectively. Here, since the instruction weighing value “8.5 kg” is larger than the weighing value “3 kg”, the process proceeds to step S7.

When the indicated measurement value is larger in the above-described size comparison, the CPU 11 divides the indicated measurement value into a plurality of pieces by updating the temporary work instruction file according to the following procedure (step S7).
First, the divided unit weight is subtracted from the indicated measured value. Then, the division unit weight is overwritten in the first line of the temporary work instruction file (indicated weighing value 8.5 kg is written in step S5), and the subtraction result is written in the second line. In the above numerical example, 3 kg is described in the first line and 5.5 kg in the second line.

Next, the difference between the subtraction result written in the second line and the division unit weight is compared. If the subtraction result in the second line is larger, the division unit weight is subtracted again therefrom. Then, the division unit weight is overwritten on the second line (the first subtraction result is written) of the temporary work instruction file, and the subtraction result here is written on the third line. This operation is performed until the subtraction result of the last line becomes smaller than the division unit weight.
In the temporary work instruction file finally obtained in this way, the numerical value described in each line becomes each instruction metric value after division. Here, as is apparent from the above calculation method, each indicated measured value after division is equal to or less than the value of the weighing, and the total value is equal to the original indicated measured value. In the above numerical example, the final temporary work instruction file consists of three lines and the number of divisions is three. However, the numerical values described in the first to third lines, 3 kg, 3 kg, and 2.5 kg are divided. It is the indicator weighing value for each subsequent time. These numerical values are equal to or less than the weighing value, and the total value is equal to the original indicated weighing value of 8.5 kg.

Next, weighing is performed according to the following procedure in accordance with the temporary work instruction file in the RAM 13 (step S8).
First, the article name written in the RAM 13 is called in step S4. Also, the instruction metric value described in the first line of the temporary work instruction file is called. Then, the weighing execution screen shown in FIG. 6A is displayed on the display unit 17. Here, a message “Please weigh 3 kg of article A” is displayed from the called data.
Next, the load cell 26 starts detecting the amount of load, and the measured weight value data is sent to the weighing support device 1 and digitally displayed on the weighing execution screen in real time.

The weighing execution screen further includes a key “Next” if the indicated weighing value is described in the next line of the temporary work instruction file, and a key “End” if there is no description in the next line. Is displayed. Here, as described above, since there is a description up to the third line in the temporary work instruction file, the “next” key is displayed.
When the operator completes the weighing in progress and presses the “Next” key, the command weighing value described in the second line of the temporary work command file is called, and the weighing screen is switched to FIG. 6B. Instead, a message prompting the second measurement divided is displayed.

Thereafter, the same processing is repeated, and when the process proceeds to the last line of the temporary work instruction file, the screen becomes as shown in FIG. 6C, and the “END” key is displayed. When the operator completes the last divided measurement and presses the “end” key, one measurement selected in step S4 is completed.
In the upper right of the weighing execution screen, the total number of weighings after division and the number of weighings currently being executed are displayed as “1/3”, and the operator is divided. The entire weighing can be grasped at any time.

  When one measurement read from the work instruction file (before division) is completed, a message for selecting whether or not to continue the measurement is displayed (step S9). Is repeated.

  Thus, according to the above embodiment, when the weighing of the indicated weighing value larger than the weighing value is executed, the weighing is divided into a plurality of weighings with the indicated weighing value smaller than the weighing value. The new instruction weighing value later is notified to the operator, and the plurality of weighings can be executed one by one. Therefore, the operator only has to perform the weighing operation according to the notified instruction, so that the work load is reduced and the flow of the weighing work can be made smooth.

Moreover, according to said embodiment, an operator can advance a measurement operation | work so that it may be easy for oneself by selecting a division | segmentation ratio freely in step S2 according to the measurement of the balance to be used. In the above description, since the weighing is as small as 3 kg, the division ratio is selected as “1”. However, when the weighing is large, it is particularly effective to use a division ratio other than “1”.
For example, when the weighing is 30 kg and the indicated measured value is 45 kg, if the division ratio is “1”, the indicated measured value is divided into 30 kg and 15 kg. Then, it is necessary to weigh 30 kg of material at a time and remove it from the scale, but it may be difficult for some workers to lift the weight of 30 kg. In such a case, for example, if the division ratio is selected as “0.5”, the indicated measured value is divided into three weighings of 15 kg each time, and if the operator raises or lowers the weight by 15 kg at the maximum, There is an advantage that measurement can be executed using the measurement support device 1 regardless of the arm strength of the operator.

As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. It is possible to change the design.
For example, in the above-described embodiment, the weighing support device 1 has the scale connection unit 20 and measures articles using a scale provided outside, but the weighing support device 1 itself has a built-in weighing unit. Then, the measurement may be performed by the measurement unit. Conversely, the weighing support device 1 and the weighing device 2 may not be connected, and the weighing support device 1 may be a device having a function of only instructing an operator only the article name and the indicated weighing value. However, in this case, it is a premise that the measuring instrument 2 has a display unit and can display the weight value being measured.

Also, the weighing file, the division ratio file, and the work instruction file shown in FIGS. 2 to 4 may be downloaded from the external management PC 4 and input to the apparatus 1 or directly using the key input unit 18. The device 1 may be input or edited. The data described in the work instruction file may include, for example, a delivery destination number in addition to the data shown in FIG.
Further, a weighing tolerance is set in the work instruction file, and when the actually weighed weight value exceeds the weighing tolerance, an alarm is generated from the alarm sound generator 21 to alert the operator. You may do it.
Further, in the work instruction file shown in FIG. 4, one weighing instruction (for example, instruction number 1) consists only of weighing one article. However, a plurality of articles are weighed in response to one weighing instruction. You may make it mix | blend these multiple articles | goods.

  In step S8 of the above embodiment, the new instruction metric value after division, that is, the data written in the temporary work instruction file is read for each line, and the measurement execution screens are displayed as shown in FIGS. ), The weighing operation is proceeded by sequentially switching the data in the temporary work instruction file, for example, “first weighing: 3 kg, second weighing: 3 kg, third weighing: 2.5 kg”. It may be a form that is sometimes displayed on one screen.

Further, the display unit 17 may be a display device other than a liquid crystal display, and may be, for example, one using an LED (light emitting diode). The key input unit 18 may not be a touch panel integrated with the display unit 17 but may be an independent button type input device.
Further, the measurement result may be stored in the nonvolatile memory 22 or may be transmitted to the management PC 4 to manage the measurement history on the PC.
Further, the apparatus 1 may be provided with a printing function so that the measurement result can be printed as a receipt or a label.
In addition, when the product of the weighing value and the division ratio is calculated in step S3, if the product does not become an integer value, the division unit weight is determined by rounding off to a predetermined number of digits after the decimal point. Good.

  The present invention is suitable for use in a weighing support apparatus that performs weighing while instructing an operator of the contents of weighing and a weighing system using the apparatus.
