Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste stored in a waste container while holding and moving one of a plurality of types of waste containers having standardized shapes. The present invention relates to a weighing device for measuring the weight of the.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a weighing device for measuring the weight of the waste stored in the waste container when the waste container is collected (for example, Japanese Patent Laid-Open No. 5-7202).
(See Japanese Patent Publication No. 3).

This weighing device measures the rising weight (waste + container) and the falling weight (container tare) when the waste container rises, and calculates the net weight of the waste from the difference. ing.

However, in order to actually perform the weight measurement, the analog voltage output from the strain gauge or the like is converted into a digital value by an A / D converter or the like, and the converted value is appropriately corrected to obtain the weight value. It is common to ask for.

For example, the weight value is y and the output value of the strain gauge is x.
Then, the correction equation when the relation is expressed by a linear equation is

[0006]

## EQU1 ## y = ax + b (1) and the relationship is as shown in FIG. However,
The measurement data shown in FIG. 13 includes three types of containers A, B,
Of C. In the equation (1), a is a linear coefficient and b is a constant term.

The values of a and b are obtained by determining the approximate straight line y by the least square method or the like from the measured data obtained by actually loading the strain gauge and shown in FIG. .

Further, in order to more accurately measure the weight of the waste, which is the content of the waste container, it is necessary to measure the weighted component in the vertical direction by the weight sensing means.

In order to measure this weighted component, (1) three or more strain gauges are arranged at equal intervals in the horizontal direction toward the container support on the vertical plane of the weighing base, and the output of these strain gauges is measured. Only the vertical component of the weight is extracted by adding.

(2) By disposing two parallel rings on both sides of the weighing base and the container support so that only the vertical component is added to the weight sensing means, the error due to the front and rear inclination is reduced. Regarding the inclination of the left and right, the weight sensing means is arranged on the left and right and the outputs thereof are added to reduce the error. It was necessary to devise such.

On the other hand, in such a weighing device, since the mechanism of the lifting device restricts the shape of the waste container to some extent,
Waste containers need to be standardized to some extent to avoid this constraint.

[0012]

When a plurality of types of standardized waste containers are used, the conventional weighing device has a problem that the weighing accuracy is poor for the following three reasons. .

(1) The balance in how the weight is applied changes greatly in the front, back, left and right.

That is, when the left and right balances are greatly deviated, the bias is canceled by adding the outputs from the weight sensing means. However, if the correction approximation formula is simplified, the error may be enlarged. . Further, the front and rear balance deviation is absorbed by a parallel link or the like, but may not be completely absorbed depending on the mounting accuracy of the parallel link or the inclination of the weighing base. In this case, if one correction approximation formula is used for all, the error may increase depending on the shape of the waste container. In other words, the correction approximation formula is 1
As a result, depending on the shape of the waste container, there may be a large deviation from the gravity center position of the weight.

(2) The weighted dynamic range is wide.

That is, there is a high possibility that a small waste container will contain light waste and a large waste container will contain heavy waste. However, when the correction approximation formula is used, the error increases as the dynamic range is expanded. Is likely to be.

(3) If the waste container is weighed while moving up and down, the error is large.

That is, since the acceleration is applied during the operation of lifting or lowering the waste container, even if the waste container has the same weight, its shape (size)
The forces exerted by the weight sensing means are not the same, and this appears as a weight error.

The present invention was devised to solve such a problem, and an object thereof is to hold one container of a plurality of types of containers whose shapes are standardized and to move the container while moving. It is an object of the present invention to provide a weighing device that uses container-specific correction data that can accurately measure the weight of the contents of a container.
