Allow the filling to start.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas filling machine that fills a container with gas such as propane gas.

[0002]

[Prior Art]

 In a conventional gas filling machine for propane gas or the like, a filling nozzle is provided at the tip of a hose, and the filling nozzle is attached to a gas filling port of a container valve provided at the upper end of the container. Further, a barcode label recording the identification number of the container is attached to the container near the container valve, and a barcode reader for reading the barcode is provided separately from the filling nozzle. Then, the filling by the filling nozzle is started when the data read by the barcode reader is proper.

Therefore, at the time of gas filling work, a bar code is read by a bar code reader after the filling nozzle is attached to the gas filling port, or the filling nozzle is attached after reading the bar code.

[0004]

[Problems to be solved by the device]

 However, in the configuration of the gas filling machine having the above-mentioned configuration, it is necessary to perform two tasks, that is, the task of mounting the filling nozzle and the task of reading the barcode with the barcode reader, and there is a problem that it takes time to perform the tasks separately. Also, if the bar code reader is not properly positioned at the time of reading with the bar code reader, a reading error is likely to occur and it may be necessary to read the bar code many times. On the other hand, in order to mount and read at the same time, it is necessary to have a filling nozzle and a bar code reader in both hands, and to perform separate operations, which poses a problem of complicated work.

In view of the above conventional problems, an object of the present invention is to provide a gas filling machine that can start filling in a short time with a simple operation.

[0006]

[Means for Solving the Problems]

 The present invention uses a filling nozzle that can be attached to the gas filling port of a container valve, and has a bar code at a position where the barcode of the bar code label attached near the container valve can be read when the filling nozzle is attached to the gas filling port. The feature is that the reader is attached integrally.

[0007]

[Action]

 According to the configuration of the present invention, if the filling nozzle is attached to the gas filling port, the barcode can be read by the barcode reader. Therefore, it is possible to perform filling with a simple work that can be done with only one hand, just by attaching the filling nozzle. Become. In addition, the barcode reading and filling start can be performed in a series of operations, which facilitates automation. In addition, by accurately attaching the barcode label, the barcode can be read stably and reliably.

【Example】

 An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, 1 is a container to be filled with LPG, and 2 is a container valve arranged at the upper end thereof. A gas filling port 3 is opened from the container valve 2 in the horizontal direction, and a bar code label 4 indicating a bar code of the identification number of the container 1 is attached below the gas filling port 3. ..

Reference numeral 5 denotes a filling nozzle that is attached to the gas filling port 3 and fills the container 1 with LPG, and the LPG is supplied from the LPG tank 7 through the hose 6. The opening / closing control of the filling nozzle 5 is performed by the control unit 8, and the detection signal from the weighing machine 9 for detecting the filling amount of the LPG on which the container 1 is placed is input to the control unit 8.

A bar code reader 11 is integrally attached to the filling nozzle 5 via a bracket 10 suspended from the filling nozzle 5, and when the filling nozzle 5 is attached to the gas filling port 3, a barcode label is attached. It is arranged so that the 4 bar code can be read. The cord 12 extended from the bar code reader 11 is clamped by the hose 6 at least in the vicinity of the filling nozzle 5 so as to be handled integrally with the hose 6. The tip of the code 12 is connected to the control unit 8, and the detection signal of the barcode reader 11 is input to the control unit 8.

In the above structure, when the container 1 is placed on the weighing machine 9 and the filling nozzle 5 is connected to the gas filling port 3 of the container valve 2, the bar code reader 11 reads the bar code label 4. Opposite position possible. Thus, the identification number of the container 1 is immediately read by the barcode reader 11 and input to the control unit 8. The control unit 8 identifies the container 1 by the read identification number and reads the data such as the weight of the empty container and the maximum filling amount from the database. Next, the filling nozzle 5 is opened to start filling the LPG, and the filling is continued until the weight in the filling completed state obtained from the read data and the weight detected by the weighing machine 9 match. To close the filling work.

As described above, according to this embodiment, the bar code is automatically read and the LPG is filled only by connecting the filling nozzle 5 to the gas filling port 3, so that the work is simple and easy. It can be easily automated.

In the above-described embodiment, the bar code label 4 is attached to the position directly below the gas filling port 3. However, as shown in FIGS. 2 and 3, the bar code label 4 is It may be attached at a position of 90 degrees in a plan view from the gas filling port 3. In that case, as shown in FIGS. 2 and 3, the bracket 13 bent in an L shape in plan view is attached to the filling nozzle 5, and the barcode reader 11 is attached to the tip of the bracket 13 to attach the barcode. It may be arranged so as to face the label 4.

[0014]

According to the gas filling machine of the present invention, if the filling nozzle is attached to the gas filling port as described above, the barcode can be read by the barcode reader and the filling nozzle is attached. It is possible to fill the gas with just a simple operation, and the barcode can be stably and reliably read by making the barcode label attachment position accurate. Thus, the barcode reading and the filling start can be performed in a series of operations, which has the effect of facilitating automation.
