Description

[Detailed Description of the Invention] The present invention provides LP gas at filling stations that sell and handle LP gas.
Related to gas cylinder filling and metering processing system.

For filling stations that sell and handle LL' gas, the amount of data handled each day is extremely large due to the large number and variety of returnable containers. Moreover, since there are a wide variety of forms to be created, data transcription is very complicated and errors are likely to occur, which requires a great deal of effort to discover. In addition, because the products handled are dangerous, an application must be submitted to the Livestock Administration. In addition, reading various types of cylinder information such as the container type, container number, and pressure expiry date from symbols stamped on the shoulder of the cylinder surface is a very troublesome task. In order to solve these problems, an LP gas filling management system as disclosed in Japanese Unexamined Patent Publication No. 74663/1988 has been proposed. This LP gas filling management system attaches a barcode label with various cylinder information to each cylinder, and scans this barcode label with a light pen reader at the time of filling to read the cylinder information and input it into a computer. The documents are created using an electronic computer. However, in such an LP gas filling management system, it is necessary to create a barcode label with various cylinder information written on it, which increases the cost. Also, it took a lot of effort to paste the code labels onto the corresponding cylinders.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a cylinder filling and weighing system that does not require the trouble of reading various types of cylinder information and can easily create IIk forms.

According to the present invention, the purpose of this invention is to provide a cylinder filling and weighing processing system that is designed to collectively process the collection of data for creating forms and the creation of forms associated with cylinder filling work in the cylinder filling team. A label with a cylinder serial number written on it is affixed to each cylinder, and a file storing various cylinder information of the cylinder corresponding to the cylinder serial number is installed in a storage device connected to the central processing unit. The cylinder serial number is entered into the central processing unit using a light pen, and the central processing unit reads out the corresponding cylinder information in the file according to the input cylinder serial number, and stores the cylinder that has been read out. This is achieved by creating a form based on the information and the cylinder weight meter data or flowmeter cumulative data sent from the filling station.

Below, the present invention will be explained based on the embodiment shown in the figures. Figure 1 shows a schematic diagram of a filling and metering processing system according to the present invention. In the figure, li and lb are for LP gas cylinders, 2a and 2b are labels with cylinder serial numbers pre-71, 3m and 3b are furrow gauges for measuring residual gas,

A scale converter is used to input the weighing signal from the machine to the central processing unit 7, and 13 is a printer for creating slips and the like.

The above are installed in the office (or station, etc.).

Note that a flow rate needle may be used instead of the weight scales 3m and 3b.

In such a configuration, the storage device 8 is preliminarily stored with a file that stores various cylinder information (pressure resistance period, tare weight, user name, etc.) for cylinders labeled with cylinder serial numbers and cough cylinder serial numbers. It is provided.

The operation of the filling and metering processing system constructed as described above will be explained based on the flowchart shown in FIG. 82 and FIG. In FIG. 1, two sets of each device are installed at the filling station and the filling process is performed in two lines, but since the processes are the same, the following explanation will only describe the filling and measuring process of one line.

1. At the filling station, the worker reads the test code written on the menu card 6m with the light pen 4m (step 1), inputs it into the central processing unit 7 by activating the label reading converter 9m. If the test code is read incorrectly, a signal sent from the central processing unit 7 via the notification display converter 11m will not turn on the three lamps of the alarm display section 5a, and the alarm will not turn on. Sounds for seconds. On the other hand, if the reading is incorrect, three lamps will turn on (11) indicating a hard error, and a buzzer will sound.

In addition, in the 21st N, the buzzer display in the case of normality indicates the sound of 1cy+Ijl, and in the case of a hard error, the buzzer display indicates the sound of 3cy+Ijl.
The two lamp displays are on, and the buzzer is beeping continuously. If the test code is read normally, the cylinder 1a is placed on the weight d3a. Next, the label 2a affixed to the cylinder 1a is scanned with the light pen 4a, the cylinder serial number is removed (step 3), and the label is entered into the central processing unit 7 via the label reading converter 9. When the central processing unit 7 receives the cylinder serial number, it receives the weight needle data of the weighing scale 3 via the scale converter 121. When the central processing unit 7 receives the weight needle data, it calculates the tare weight from among the various cylinder information stored in the file in the storage device 8 based on the previously read cylinder serial number, and calculates the tare weight,
The remaining amount of gas is calculated by subtracting the tare weight from the weight needle data. Based on various information about the old cylinder, the following judgment is made.

-) Serial number, etc. not registered... Determine whether the cylinder serial number on the label affixed to the cylinder is registered in the file.

(/'1 Pressure resistance expiry date... Determine whether the pressure resistance period specified on the cylinder has passed (Read the pressure resistance period from the file and compare it with today's date. Also, if the expiration date is one month before, mark it on the sales slip. ).

) Hard error: Determining whether a failure has occurred in the configured nodes.

These determination results are distinguished and displayed by flashing blue, yellow, and red lamps on the alarm display section 5a, or by sounding a buzzer. Each alarm display form is as shown in the figure. If these discrimination results are normal, a visual appearance inspection is performed. In this visual appearance inspection, the worker visually inspects the cylinder for scratches, dents, etc. that may interfere with the use of the cylinder, and if it is determined that the cylinder has a poor appearance, the menu card 6a
The defective code written in is read with the light pen 4a (step 4) and inputted to the central processing unit 7 via the optical cable 10 and the label reading converter 9a.

When the defective code is correctly read by the central processing unit 7,
A signal from the central processing unit 7 causes the buzzer of the alarm display section 5a to sound for one second.

As a result of the visual appearance inspection, if it is determined to be a good product, the cylinder 1m is sent to a filling station (not shown) (step 5), and the cylinder 1a is filled. Next, it is determined whether the processing from step 2 to step 5 has been completed after 1 user - minutes, and if it has not been completed, repeat step 2.
perform the following operations.

When the processing for one user is completed, the end code written on the menu card 6 is read with the light pen 4a (step 6), and the optical cable is 10 m away.

The data is input to the central processing unit 7 via the label reading converter 91. When the end code is correctly read by the central processing unit 7, the alarm display section 5 is activated by a signal from the central processing unit 7.
The buzzer a will sound for 1 second.

When the central processing unit 7 receives the end code, it sends the printer 13
Output the slip. These slips include sales slips and sales slips (receipts). In addition, a daily balance sheet and a filling diary are printed out from the printer 13 as necessary.

After outputting the slip, it is determined whether or not there is a next user, and if there is a next user, the process from step 2 is repeated for the next user's cylinder. Terminates if there is no next user.

If the customer code, etc. is mixed in, the serial number is not registered, the voltage resistance period has expired, or the appearance is defective, the process shown in the flowchart in FIG. #I3 is performed, and the process returns to step 2 in FIG. That is, if the cylinder serial number is not registered, the cylinder is removed from the line and the central processing unit 7 registers the cylinder serial number with the user. If the customer code is mixed in, the cylinder is removed from the line and placed in the registered user's location. If the withstand voltage has expired, the cylinder is removed from the line and conventional pressure expiration processing is performed. In the case of an appearance defect, the cylinder is removed from the line and the conventional appearance defect treatment is performed.In the case of a hard error, a system engineer is called to deal with it, and then step 1 is performed to determine whether it is normal. Check.

In the explanation of the above embodiment, a weight needle is used, but a flowmeter may be used instead of the weight needle, and in the case of a flowmeter, the central processing unit 7 receives the flowmeter integrated data after step 6 is completed. Do it like this.

As described above, according to the present invention, a label with only the cylinder serial number written on it is attached to the cylinder, and the cylinder serial number on the label is read using an optical reading method using a light pen, so that the following effects can be obtained. I can do it. First, since it uses an optical reading method, there is no need for explosion-proof measures. Furthermore, even if there is a change in specifications (increase in the number of cylinder containers, increase in the number of stores, etc.), the change can be easily made. - There are no errors because the table is created using the central processing unit and printer. Furthermore, the empty state can be checked at a glance by using the weight needle to measure the remaining amount.
