Here, the balance main body 1 has an upper surface serving as a placing portion 1A on which an object to be measured is placed, and a lower surface side provided with four leg portions 1B, 1B, ... The scale main body 1 is configured as a platform scale, and when the weighing object is placed on the placing section 1A, an electric signal corresponding to the weight is output to a control unit 8 described later.

Reference numeral 3 denotes a control panel, which is attached above the balance body 1 by a support 2 with a predetermined inclination angle, and on the front surface of the control panel 3, a weighing value display 4, which will be described later, and a target. A value display 5, a keyboard 6, and an analog display 7 are provided.

Numerals 4 and 5 denote a weight value display and a target value display, respectively, which are arranged in front of the control panel 3, and the weight value display 4 and the target value display 5 are, for example, liquid crystal or LED. It is composed of a digital display, which displays the present weighing value W and the weighing target value W0 as described later.

Reference numeral 6 denotes a keyboard as an input means. The keyboard 6 is composed of ten keys for inputting numerical values and various keys for resetting, and an operator operates the keyboard 6 to operate the control unit 8 In addition, for example, the measurement target value W0 or the like is input.

Reference numeral 7 denotes an analog display as an analog display means. The analog display 7 is composed of a liquid crystal, an LED or the like like the measurement value display 4, the target value display 5, etc. It is connected to the. The analog display 7 is adapted to display the ratio of the present weighing value W to the weighing target value W0 in percentage by the scale section 7A.

Reference numeral 8 denotes a control unit that is provided inside the control panel 3 and includes a microcomputer, etc. The control unit 8 has an input side connected to the balance body 1 and the keyboard 6 and the like, and an output side connected to the weighing value display 4. , Connected to target value display 5 and analog display. The control unit 8 stores the program and the like shown in FIG. 4 in its storage circuit, and performs a calculation process of the ratio of the present weighing value W to the weighing target value W0.

In the storage circuit of the control unit 8, the weighing target value W0 of the weighing object (not shown) input by the keyboard 6 is stored in the storage area 8A in a renewable manner. There is.

The balance according to the present embodiment has the above-described configuration, and its operation will be described next focusing on the operation of the control unit 8.

First, by turning on a power switch (not shown), the weighing main body 1 is brought into a state of being capable of weighing, and the processing operation is started. In step 1, the operator inputs the target weight of the weighing object from the keyboard 6. Then, the weighing target value W0 is set, and the process goes to step 2 to display the target value W0 on the target value display 5 of the control panel 3.

Then, when the object to be weighed is filled in a container (not shown) arranged on the placing portion 1A of the balance body 1, the balance body 1 causes the control unit 8 to check the present measured value W. Since the corresponding signal is output, in step 3, the present weighing value W output from the balance main body 1 is read, and in step 4, the weighing value display 4 displays this weighing value W.

Next, in step 5, the current measured value W is replaced as the variable W1, and the process moves to step 6 where the ratio F of the variable W1 to the target value W0 is

[0022]

[Formula 1] F = (W1 / W0) × 100 The percentage is calculated by the calculation, and in step 7, the ratio F obtained from the calculation of the above formula 1 is displayed on the scale 7A of the analog display 7 provided on the control panel 3. Display as the amount of analog.

Then, in step 8, it is judged by the keyboard 6 whether or not the target value W 0 has been updated. When the judgment is “NO”, the process returns to step 3 and the current measured value W from the balance body 1 is again measured. Is read, and the subsequent processing is sequentially repeated.

Here, since the operator can immediately recognize from the display of the scale portion 7A of the analog display 7 that the current measured value W becomes almost a percentage of the target value W0, the maker has a scale. While confirming the movement of the portion 7A, it is possible to continuously replenish powder or the like as the object to be weighed into the container, and it is possible to continue the weighing operation all at once up to the target value W0. When the display on the graduation portion 7A approaches 100%, if the objects to be weighed are gradually replenished, the entire weighing operation can be performed quickly and accurately.

Further, if “YES” in the step 8, it means that the target value W0 is changed, and therefore the process returns in the step 9 and the processes of the step 1 and subsequent steps are performed again.

Thus, in the present embodiment, when the object to be weighed is being filled into the container placed on the placing portion 1A, the present weighing value W and the weighing target value W0 are displayed on the weighing value display 4 And the target value display 5 and the analog display 7 can display the percentage of the current weighing value W with respect to the target value W0 by means of the scale portion 7A. It is possible to surely inform the weighing operator of how much the container is filled, and for example, it is possible to easily perform work such as replenishment of an object to be weighed, and also to perform accurate weighing work.

In particular, in the present embodiment, since the ratio of the current measurement value W of the object to be measured to the target value W0 can be displayed as an analog amount during the measurement operation, the operator can The object to be weighed can be continuously replenished by using the display of the analog display 7 as a guide, and the weighing work can be quickly performed to the end.

Further, even when the object to be weighed is a liquid and the liquid level in the container is wavy, or when weighing is performed in a place where there is vibration, the display amount displayed on the scale 7A of the analog display 7 is There will be no large fluctuations, and the worker can always keep track of the amount of the measuring object to be replenished thereafter.

In the embodiment, step 6 in the program shown in FIG. 4 shows a specific example of the ratio calculating means which is a constituent feature of the present invention.
