Description

[Detailed description of the invention] Industrial application field The present invention transports a filled container from an inlet side to an outlet side,
The present invention relates to a filling management device that manages excess or deficiency in the amount of filling into the filling container on the discharge side in a filling device that fills the liquefied gas during the transfer.

A conventional liquefied gas filling device is constructed as shown in FIG. Filling container 2 brought to the filling factory by truck 1
The remaining gas amount is determined by weighing with the carry-in scale 3, and the necessary charge is made based on the determined remaining gas amount and the capacity of the filling container 2.
% amount is determined, and this required filling amount is set in the filling machine 4 at the carry-in position, and the filling container 2 is moved to the empty filling R4. The filling fi 4 is installed on the turntable 5 and driven to rotate in the direction of the arrow, and is filled with liquefied gas via a filling valve (not shown) before reaching the carry-out scale 6. The filling valve is closed when the filling reaches the required filling amount even before reaching the discharge side. The filled container 2 that has arrived at the carry-out side is transferred to the carry-out side scale 6 with the filling valve removed, and overfilling is checked based on the weighed value and the like. The filled container 2, which has been filled with overfill, is transported out of the filling factory by a truck 7.

Figure 3 shows the configuration of an indicator 8.9 installed near the carry-in side scale 3 and the carry-out side scale 6. The indicator 8.9 determines the filling amount and checks for overfilling as follows. It has been implemented.

The indicator 8.9 is connected via a communication line 10 to a host computer (not shown). When the barcode label 11 affixed to the shoulder of the filling container 2 placed on the carry-in scale 3 as shown in FIG. 4 is scanned and read by the barcode reader 12, the barcode label 11 The unique code N read from is sent to the post computer B via the first interface 13 and the communication line 10.

In the host computer, individual data such as wind S jlk 'r n , capacity jtC1 expiration date, and previous filling 1 are registered in advance for each unique code N of each filling container 2, and the unique code N from the indicator 8 is registered in advance. When the host computer receives the inquiry, the host computer reads and returns individual data such as the tare weight Tn and the capacity C indicating whether the container is filled with M kilograms. The first calculation unit 14 of the indicator 8 calculates the residual gas jlGI Tn remaining in the filling container 2 based on the tare weight Tn of the filling container 2 read out from the host computer and the weight value G1 of the carry-in scale 3. =g@:n is sent to the host computer B via the first interface 13 along with the unique code N.
is sent and used to calculate usage, etc. The second calculation unit 15 calculates the required filling amount c−g=Go from the capacity C of the filling container 2 read from the host computer B and the remaining gas amount g calculated by the first calculation unit 14. , the required filling amount is displayed on the first display section 16.

The filling container 2 for which the required filling JiGo has been determined is transferred from the carry-in side scale 3 to the filling machine 4 on the turntable 5, and the calculated required filling amount Go is set in the filling 814 as the filling port a value.

In the indicator 9, the barcode label 11 is scanned by the barcode reader 17, and the unique code N is sent to the host computer via the second interface 18 to inquire about individual data. The host computer B reads out the tare weight T1 and the capacity C again based on the unique code N and sends them back. The third calculation unit 19 of the indicator 9 calculates the actual filling amount G3 from the weight value G2 of the carry-out scale 6 and the tare amount Tn read from the host computer B. The calculated actual filling amount G3 is calculated in the fourth calculation unit 20 with the capacity C of the individual data read from the host computer B to check whether there is overfilling, and the excess or deficiency amount is displayed on the second display. It is displayed in section 21. Here, overfilling occurs when the display on the second display section 21 becomes "+". Further, when the sign bit of the output of the fourth calculation unit 20 is “-”, the second interface 18 sends the output value of the third calculation unit 19 at that time to the host computer B together with the unique code N. The host computer B records each unique code N as the filling amount at the time of shipment.

For filled containers 2 in which "+" indicating overfilling is displayed on the second display section 21, after the overfilled liquefied gas is discharged and removed, the filled container 2 is recorded in the host computer B and shipped. There is.

Problems to be Solved by the Invention In such a conventional configuration, a unique code N is inputted via the barcode reader 12 on the carry-in side to determine the required filling amount, and overfilling also occurs on the carry-out side. It is necessary to re-enter the code through the barcode reader 17 to check the unique code N, and if a barcode label and barcode reader are used to input the unique code N, A total of two barcode readers 12.17 are required on the export side.

Alternatively, if the unique code N is entered by operating a numeric keypad, key-in operations are required twice on the loading and unloading sides, which is cumbersome, and there is a risk of misreading or key-in operation errors by the operator. remains, reducing reliability.

The present invention does not require re-inputting the unique code on the export side.
It is an object of the present invention to provide a filling management device capable of checking overfilling based on individual data.

Means for Solving the Problems The filling management device of the present invention is a filling device that transports filling containers from the carry-in side to the carry-out side, and fills the filling containers with liquefied gas during this transfer. a reading means for outputting registered individual data based on a unique code of the filling container inputted on the carry-in side; a register means for storing the individual data outputted from the reading means on a first-in, first-out basis; and a filling container on the carrying-out side. The present invention is characterized by further comprising a determining means for displaying whether or not the amount of filling is excessive or insufficient based on the individual data read from the register means.
