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 is fixed to the lower part of the weighing platform 3, with a load cell 4, 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. For this print, the truck driver or truck driver
When the scale staff inserts such a shipping slip into the print slot of the measuring device, the measurement results are automatically printed in the specified location, but it is necessary to check whether the truck is empty or loaded with cargo beforehand. Check and set the changeover button on the meter to either 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" field of the slip, and when set to the total weight position, the "total weight" is printed.
is printed in the field.

Once the gross weight and tare are measured, the net weight of the cargo is calculated by operating the measuring device as appropriate.The weighing results are either printed in the ``Total weight'' column, or are displayed in the ``Tare'' column. 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 weight recording method of the scale, the weighing order of tare and total weight is determined in advance, and it is detected whether a recording operation has already been performed on the weight recording paper,
A weighing truck scale characterized in that, based on this detection, the weighing result is automatically recorded on the weighing recording paper at the predetermined position for the total weight or the predetermined position for the tare weight. This is achieved by a recording method.

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. That is,
At this location, it is stipulated that the weight must first be tared. This weighing result is supplied to a measuring device (not shown), and as shown in FIG. 3, "5210" is printed in the "tare" column of the shipping slip, for example. 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 weight 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 or that a number is printed in any of the other columns, and based on this detection signal, The weighing results are automatically printed in the "total weight" column of the slip. Also, as mentioned above, when an empty truck arrives on platform 3, there are no numbers or letters printed in the "Tare" field or any other fields on the slip, so the measuring device detects this and Based on this detection signal, control is performed so that the weighing result "5210" is printed in the "Tare" column.

Note that various known methods such as optical methods and electromagnetic methods may be applied to detect whether numbers or letters are printed in the "Tare" column or other columns.

The above description has been made of the case where the gravel is carried out, that is, the tare is weighed first, but the same applies to the place where the gravel is carried in, that is, the case where the total weight is first weighed. In this case, the incoming delivery slip is used as the weight recording sheet, and when the weight results are obtained, if it is detected that there is no printing on this recording sheet, the "Total weight" column will be changed. This weighing result will be printed. When the empty truck is then weighed, the "total weight" of the paper is
Or, it is detected that letters or numbers are printed in any other column, and based on this detection, the weighing result at this time is automatically controlled to be printed in the "Tare" column of the paper. Ru.

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 embodiment, it is detected whether or not there is any printing on the shipping slip or receiving slip as a recording paper, and the "tare" or "total weight" is detected.
I tried to print the weighing results in the column, but
When printing on recording paper, this recording paper may be encoded and stored, and based on this recording, it may be detected whether a printing operation has been performed. To memorize this, the numbers printed in the "Code Number" column shown in Figure 2 or Figure 3 may be memorized, or the code number may be recorded magnetically somewhere on the paper in advance. , this number may be stored when printing on this paper for the first time. In addition, various methods can be considered for detecting whether or not a printing operation has been performed on paper.

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.
