DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rotary table type high-pressure gas filling apparatus according to the present invention will be described below with reference to FIGS.

A plurality of filling machines 2 are arranged on a rotary table 1 shown in FIG. 2 to form a filling station A. The carry-in line B to the filling station A is configured as follows.

[0010] The loading line B is a loading conveyor 3 on which empty cylinders brought into the platform are loaded first.
a, 3b,..., and the receiving conveyors 3a, 3b,.
The main transport conveyor 4 extends from the end of the main transport conveyor A to the filling station A, and an auxiliary transport conveyor 5 provided in the middle of the main transport conveyor 4.

As shown in FIG. 3, the cylinder placed on the main conveyor 4 is a cylinder type reading station Ca.
The cylinder type is read when passing through the gate 13 of
In accordance with the determined cylinder type, the height of the barcode reader 6 of the next identification number reading station Cb is immediately controlled.

The identification number reading station Cb includes:
A cylinder rotating device is provided. The cylinder rotating device is
The bar code reader 6 that has completed moving the loaded cylinder 12 to an appropriate reading height is displayed on the bar code label 7.
Rotate until can be read.

The identification number read from the bar code label 7 is referred to a host computer (not shown) installed at the filling station office, and the cylinder ledger is searched by using the identification number as a search key to find the cylinder type. , Tare weight, expiration date, etc. are read.

A non-contact tag is attached to each cylinder 12 handled by the high-pressure gas filling apparatus.
The non-contact tag 15 is a data carrier capable of reading and writing data in a non-contact manner using light or electromagnetic waves as a medium.

The identification number reading station Cb includes:
In addition to the bar code reader 6, a writing device 16 for writing data to the non-contact type tag 15 is provided.
Indicates the type of container, the tare weight, and the expiration date of each cylinder obtained by inquiring the filling office.
Write to.

At the identification number reading station Cb, the residual gas is calculated from the weight measured by the weighing machine 8 and the tare weight. Identification number reading station C
The cylinders that passed through “b” are stored in the journalizing station D in accordance with the type of cylinders answered from the cylinder ledger.
The kg cylinder is pushed out to the auxiliary transport conveyor 5 by the journalizing device 9. The 50 kg cylinder is transported by the main transport conveyor 4 as it is.

The cap 11 is removed from the 50 kg cylinder passed through the journalizing station D by the cap removing machine 10 at the cap removing station E.
The 50 kg cylinder passed through the cap removal station E and the 20 kg cylinder sent to the auxiliary transport conveyor 5 are sent to the orienteering station F.

The filling nozzle 19 of the filling machine 2 on the rotary table 1 is installed toward the outside of the rotary table 1 as schematically shown in FIG. The cylinder 12 is rotated until the filling port faces upward in the transport direction.

When the position correction of the cylinder at the orienteering station F is completed, the automatic insertion station H
It is carried in. At the automatic insertion station H, the filling has been completed, the cylinder has been sent from the rotary table 1 to the unloading line I, and the filling machine 2 at the filling station A capable of receiving the next cylinder has already been corrected at the orienteering station F. Automatically insert the cylinder.

The cylinder 12 carried into the filling machine 2 on the rotary table 1 has a filling nozzle 19 at a filling port of the container valve.
Is automatically mounted, and the handle 17 of the container valve 14 is
The filling is performed by driving in the opening direction by the opening device 18 shown in FIG.

Each filling machine 2 includes, in addition to a filling nozzle 19 and an opening device 18, a reading device 21 for reading data from a non-contact tag 15 attached to a measuring device 20 and a cylinder 12 at a filling position, and a filling device 21. A control device 22 and the like are provided. Each filling control device 22 includes a cylinder type, a tare weight,
The operation is performed based on the expiration date.

The filling control device 22 does not perform filling for a cylinder whose expiration date read by the reading device 21 from the non-contact type tag 15 has expired. The filling control device 22 fills the cylinder that has not expired by opening the filling valve 23 until the weighing value of the weighing device 20 reaches a fixed amount based on the cylinder type and the tare weight. , The handle 17 of the container valve 14 is driven in the closing direction, and after the closing is completed, the filling nozzle 19 is removed from the filling port.

When the cylinder arrives at the unloading line I, the filled cylinder is pushed out to the unloading line I and taken into the excess / deficiency check station K by the automatic unloading station J.

The excess / deficiency check station K is provided with a weighing machine and a reading device. The reading device compares the weight range determined by the type of cylinder read from the non-contact type tag 15 with the weighed value of the filled cylinder. Then, the filling amount is checked for excess or shortage.

The cylinder of the excess / deficiency check station K is carried into the closure confirmation station L by the conveyor of the carry-out line I, and the gas leak detector detects the closure failure of the handle of the container valve 14.

The cylinder whose filling amount is determined to be appropriate at the excess / deficiency check station K and whose closure is determined to be good at the closure confirmation station L is conveyed to the lower side. In addition,
The stopper check station L is also provided with a reading device, and the reading device reads the non-contact type tag 15 from the expiration date cylinder and the excess / deficiency check station K.
Alternatively, the cylinder determined to be defective at the plug check station L is removed from the unloading line I via the defective line 24.

At the seal cap station M, a seal cap is attached to the safety valve portion of the container valve of the cylinder when the filling amount is determined to be appropriate and the closure is determined to be good. The cylinders that have passed through the cap station N are first, second,... Journal entry stations O ₁ , O ₂ ,.
Journalized by ...

With this configuration, the writing device 1
6 writes data to the non-contact type tag 15, and on the side of the filling station A, the reading device 21 reads out the content of the non-contact type tag 15 attached to each cylinder 12 and the filling control device 22 controls the filling. The filling can be definitely performed without the side of the rotary table 1 communicating with the outside.
