Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for recording weights on a truck scale.

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 arranged in the pit 6, and the load cells 4 and 5 detect the weight of the truck due to the drag force on the bottom surface, but when the truck is empty, 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 receipt/shipment 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 machine is empty or loaded, and set the changeover switch on the measuring device to the tare position or the gross weight position. That is, 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.

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 toggle switch on the meter must be set accordingly to determine what to print. 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-mentioned points, and an object of the present invention is to provide a weight recording method 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 scale weight recording method, it is automatically detected whether the weighing result is larger or smaller than a predetermined weight, and if it is larger than the predetermined weight, the weighing result is recorded as the total weight on the weighing recording paper. Weighing record of a truck scale, characterized in that when the weight is smaller than the predetermined weight, the weighing result is recorded in the predetermined tare position of the weighing recording paper. 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 brought in and taken out, and in FIG. 1, a truck that has climbed a slope 1 stops on a platform 3 and its weight is measured. This weight result is supplied to a digital measuring device (not shown) and compared with a predetermined weight set in this measuring device. This predetermined weight is set to, for example, 9000Kg, and if this truck is now empty and its own weight, that is, the tare weight is 8200Kg, it will be detected that this weighing result is smaller than the set weight, and this detection signal will indicate the weight at this time. The result is automatically printed as "8200" in the "Tare" column of the receipt/shipment slip, as shown in Figure 3. At this time, other "time" of the slip
Data corresponding to columns such as "date" and "car number" may also be printed at the same time.

Also, when this truck is loaded with gravel and climbs up slope 2 and stops on platform 3, its total weight is measured.
If it is 9200Kg, the total weight is 8200Kg + 9200Kg =
The weight is 17,400Kg, and this weight result is automatically recorded in the "Total weight" column of the receipt/shipment slip. That is,
In this case, the above specified weight in the measuring device is 9000Kg.
It is detected that the weighing result is larger, and the control is performed so that it is automatically printed in the "total weight" column based on this detection signal.

In general, a truck's dead weight, or tare, has a value that is determined in stages, and the allowable load capacity is standardized accordingly. For example, a truck with a tare weight of approximately 8,000 kg has an allowable load capacity of 10 tons, and a truck with a tare weight of approximately 5,000 kg has an allowable load capacity of 6 tons; in both cases, if the truck is fully loaded with gravel, the total weight is Over 9000Kg. In other words, in this embodiment, the predetermined weight is set at 9000 kg, so the method according to this embodiment is applied to all trucks that exceed this weight when loaded with gravel and are below this predetermined weight when empty. may be applied.
In other words, when loaded with gravel, the total weight is
Applicable to all trucks that weigh more than 9000Kg but less than 9000Kg when empty. Therefore, the scope of application is extremely wide. Generally, a truck can be loaded with a load that weighs more than its own weight, so the method according to the present embodiment is applicable to, for example, a 5-10 ton truck.

As described above, according to this embodiment, it is no longer necessary for the truck driver or attendant to check whether the truck weighs tare or gross weight each time and sets the changeover switch accordingly, unlike in the past. Not only is the recording operation simple, but also operational errors can be prevented.

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, the predetermined weight in the digital measuring instrument is set to 9000 kg, but the predetermined weight is not limited to this, and may be set to a value depending on the receiving/shipping condition. Alternatively, the predetermined weight may be set in stages and switched depending on the situation.

The weight recording form is not limited to the format of the receipt/shipment slip shown, and any weight recording form that records tare weight and total weight is applicable.

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.
