Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weight recording system for truck scales.

Truck scales are generally used to measure the net weight of gravel, various materials, or various parts loaded on a truck. Fig. 1 schematically shows an example of a truck scale.A truck that has climbed either the left or right slope 1 or 2 stops on a weighing platform 3, and a load cell 4 fixed at the bottom of the platform 3 stops. , 5, the weight is measured.
That is, the weighing platform 3 and the pair of load cells 4 and 5 fixed thereto are disposed inside the bit 6, and the load cells 4 and 5 detect the weight of the truck due to the drag force on the bottom surface. In this case, the tare of the truck will be measured, and if the truck is loaded with cargo, the total weight including the cargo will be measured. Although not shown, this measurement result or weighing result is calculated by a digital measuring device that receives detection signals from the load cells 5 and 6, and the weight is displayed as a digital value on the display section of this measuring device. The measurement results at this time are printed on the shipping slip as shown in Figure 2. To print this, when a truck driver or truck scale staff inserts such a shipping slip into the print slot of the measuring device, the measurement results are automatically printed in a predetermined position. Check whether the meter is empty or loaded, and set the switch button on the meter to the tare position or the gross weight position. In other words, when set to the tare position,
The weighing result at that time is printed in the "Tare" column of the slip, and when set to the total weight position,
It is printed in the "Total weight" column.

When the gross weight and tare are measured, the net weight of the cargo can be calculated by operating the measuring device as appropriate, or the weighing results can be printed in the "Total Weight" column, or the "Tare" column can be calculated. The switching button on the measuring instrument must be set each time to determine what is to be printed. Such operations are troublesome, and if performed incorrectly, the image will be printed in the wrong position.

The present invention has been made in view of the above points, and an object of the present invention is to provide a weight recording system for a truck scale with excellent operability. This purpose, according to the present invention, is to automatically measure the tare weight of the truck and the total weight of the loaded truck using a truck scale, and to record these weighing results at respective predetermined positions on the weighing record sheet. The truck that was
In the weighing and recording method of the scale, first the tare of the truck is weighed, and then the total weight of the loaded truck is weighed, and the tare weight of the truck is weighed, and the total weight of the loaded truck is weighed. When it is detected that the total weight has not been recorded yet, the weighing result is automatically recorded at a predetermined position for the total weight on the weight recording paper based on this detection, and when it is detected that the weight has not been recorded yet, This is achieved by a weighing recording method for a truck scale, characterized in that based on this detection, the weighing result is automatically recorded at a predetermined position for the tare on the weighing recording paper. .

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

This embodiment is applied, for example, to a place where gravel is transported, and an empty truck that has climbed up a slope 1 in FIG. 1 is tared on a platform 3. This weighing result is supplied to a measuring device (not shown), and as shown in Figure 3, it is written as ``5210'' in the ``tare'' column of the shipping slip.
is printed. At this time, corresponding data may also be printed in other columns of the slip such as "time,""date," and "car number." Next, this truck is loaded with gravel, climbs the slope 2, and the total weight is weighed on the platform 3. This weighing result is supplied to the measuring device and automatically printed in the "Total Weight" column of the slip. At this time, the measuring device detects that "5210" is printed in the "tare" column of the slip, and based on this detection signal, the weighing result at this time is automatically added to the "total weight" of the slip. is controlled so that it is printed in the field. Also, as mentioned above, when an empty truck comes onto platform 3,
Since no number has yet been printed in the "Tare" column of the slip, the measuring instrument detects this and prints the weighing result "5210" in the "Tare" column based on this detection signal. controlled so that

Note that various known methods such as optical methods and electromagnetic methods may be applied to detect whether or not numbers are printed in the "tare" column.

In addition, it detects that a number is printed in the "tare" field, and also detects that a field that is printed at the same time, such as "car number", is printed at the same time as this printing, thereby indirectly indicating the "tare" field. It may also be possible to detect that it is printed in a column.

In other words, according to this embodiment, there is no need for the truck driver or attendant to check whether the weight is tare or gross weight each time and set the changeover switch accordingly, unlike in the past, and the weight recording operation is simplified. Not only is this simple, but it also prevents operational errors.

The embodiments of the present invention have been described above, but of course the present invention is not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, the place where gravel is taken out has been described, but it can also be applied to a place where gravel is brought in. In any case, it is best to first tare the truck using a truck scale.

As described above, the weight recording method of the truck scale of the present invention eliminates the need to operate the changeover switch each time as in the conventional method, and ensures that the weight results are recorded in the designated column of the recording sheet. This is guaranteed.
