Description

本発明はガス充填装置に係り、特に充填量を個別に表示する表示器を複数有するガス充填装置に関する。   The present invention relates to a gas filling device, and more particularly, to a gas filling device having a plurality of indicators for individually displaying the filling amount.

例えば、天然ガスを圧縮した圧縮天然ガス（ＣＮＧ）を燃料にして走行する自動車（ＣＮＧ車）の開発と共に圧縮天然ガスを自動車の燃料タンクに供給するガス供給装置の実用化が進められている。この種のガス供給装置では、圧縮されたガスをガス蓄圧器に貯蔵しておき、ガス充填ホースの接続カプラをＣＮＧ車の接続カプラに接続し、ガス充填ホースの先端部に連通された三方弁を切り替え操作することによりガス蓄圧器に貯蔵されたガスをＣＮＧ車の燃料タンクに充填するように構成されている。   For example, along with the development of automobiles (CNG cars) that run using compressed natural gas (CNG) compressed with natural gas as fuel, a gas supply device that supplies compressed natural gas to a fuel tank of the automobile is being put to practical use. In this type of gas supply device, a compressed gas is stored in a gas pressure accumulator, a gas filling hose connection coupler is connected to a CNG vehicle connection coupler, and a three-way valve communicated with the tip of the gas filling hose The gas stored in the gas pressure accumulator is filled in the fuel tank of the CNG vehicle by switching operation.

そして、従来のガス充填装置では、筐体の前面側と後面側の夫々で同時にガス充填が行えるように２つのガス充填系路を有しており、且つ各ガス充填系路には、電磁弁、流量計、圧力計、温度センサ、遮断弁、調整弁、安全弁などの機器が配設されているので、筐体内部の空間のうち電気系統の複数の基板を収納するスペースが制限されていた。そのため、従来は、一つの防爆容器に表示基板、計測基板、電源基板、インターフェイス基板などの複数の基板を集中的に配置していた（例えば、特許文献１参照）。   The conventional gas filling apparatus has two gas filling paths so that gas can be filled simultaneously on the front side and the rear side of the casing, and each gas filling path has an electromagnetic valve. Since devices such as flow meters, pressure gauges, temperature sensors, shut-off valves, regulating valves, and safety valves are installed, the space for housing multiple boards in the electrical system within the space inside the housing was limited. . Therefore, conventionally, a plurality of substrates such as a display substrate, a measurement substrate, a power supply substrate, and an interface substrate are intensively arranged in one explosion-proof container (see, for example, Patent Document 1).

また、上記圧縮天然ガス（ＣＮＧ）以外にも燃料電池の開発に伴って高圧に圧縮された水素を燃料として発電を行う燃料電池システムの被充填タンクに水素を充填するガス充填装置の開発も進められている。この水素充填を行うガス充填装置においても上記圧縮天然ガス（ＣＮＧ）の充填を行う装置と同様な構成なっている。
特開２００２−３７２１９１号公報 In addition to the above-mentioned compressed natural gas (CNG), the development of a gas filling device for filling hydrogen into a tank to be filled in a fuel cell system that generates electricity using hydrogen compressed to a high pressure as a fuel along with the development of the fuel cell is advanced. It has been. The gas filling device for performing hydrogen filling has the same configuration as the device for filling the compressed natural gas (CNG).
JP 2002-372191 A

しかしながら、上記のように構成されたガス充填装置においては、一つの防爆容器に表示基板、計測基板、電源基板、インターフェイス基板などの複数の基板を集中的に配置しているため、防爆容器の容積が大型化してしまい、しかも防爆強度を持たせるためにより肉厚にまた接合面をより長くする必要があった。よって、防爆容器自体が大型化してしまい、且つ、鋳物で形成されているので、かなりの重量があり、例えば、工場での組み立て作業を行う際に作業員が２人で持ち上げながら筐体のフレームに取り付けることになり、作業効率を上げることが難しかった。   However, in the gas filling apparatus configured as described above, since a plurality of substrates such as a display substrate, a measurement substrate, a power supply substrate, and an interface substrate are concentrated in one explosion-proof container, the volume of the explosion-proof container However, in order to provide explosion-proof strength, it has been necessary to increase the thickness and lengthen the joint surface. Therefore, the explosion-proof container itself is increased in size and is formed of a casting, so there is a considerable weight. For example, when performing assembly work in a factory, two workers lift up the frame of the housing. It was difficult to improve work efficiency.

さらには、定期点検や修理等で各基板を防爆容器から取り出してメンテナンスを行う際にも、大きくて重い防爆容器を取り出して点検作業または修理作業を行うことになるので、作業員のメンテナンス作業に余計な労力が必要になるという問題があった。   Furthermore, when carrying out maintenance by taking out each board from the explosion-proof container for periodic inspections and repairs, etc., the large and heavy explosion-proof container must be taken out for inspection or repair work. There was a problem that extra labor was required.

そこで、本発明は上記課題を解決したガス充填装置を提供することを目的とする。   Then, an object of this invention is to provide the gas filling apparatus which solved the said subject.

本発明は、筐体に設けられた複数の表示部と、該表示部を駆動する表示基板を内部に有する複数の防爆容器と、被充填タンクに圧縮ガスを充填するための充填系統と、該充填系統に設けられ、前記被充填タンクに供給された圧縮ガスの充填量を計測する計測手段と、前記充填系統に設けられた弁と、前記計測手段により計測された圧縮ガスの充填量に基づき弁開度を制御するための制御基板と、各機器へ電力を供給するための電源供給用基板と、前記制御基板と前記電源供給用基板とのうち少なくとも何れか一つの基板を前記複数の防爆容器の何れかに収納し、他の基板を他の防爆容器に収納したことを特徴とする。   The present invention includes a plurality of display units provided in a housing, a plurality of explosion-proof containers having a display substrate for driving the display unit, a filling system for filling a tank to be filled with compressed gas, Based on the measurement means provided in the filling system for measuring the filling amount of the compressed gas supplied to the tank to be filled, the valve provided in the filling system, and the filling amount of the compressed gas measured by the measuring means. At least one of the control board for controlling the valve opening degree, the power supply board for supplying power to each device, and the control board and the power supply board is the plurality of explosion-proof boards. It is housed in one of the containers, and another substrate is housed in another explosion-proof container.

本発明によれば、制御基板と電源供給用基板とのうち少なくとも何れか一つの基板を複数の防爆容器の何れかに収納し、他の基板を他の防爆容器に収納したため、複数の基板を複数の防爆容器に分散配置することで、防爆容器を小型化及び軽量化することができ、これにより、防爆性能維持の容易化、組み立て作業及び点検・修理作業の際の作業効率を高めることが可能になる。   According to the present invention, at least one of the control board and the power supply board is stored in one of the plurality of explosion-proof containers, and the other board is stored in another explosion-proof container. Distributing and disposing multiple explosion-proof containers makes it possible to reduce the size and weight of the explosion-proof containers, thereby facilitating maintenance of explosion-proof performance and improving work efficiency during assembly work, inspection work, and repair work. It becomes possible.

また、制御基板と電源供給用基板とを別々に防爆容器に収納したことで、制御基板が電源供給用基板から発生する電磁ノイズの影響を受けて誤動作することを防止できると共に、電源供給用基板が発生する熱の影響を制御基板が受けなくなるので、制御基板の寿命を延ばすことができる。   In addition, since the control board and the power supply board are separately housed in the explosion-proof container, the control board can be prevented from malfunctioning due to the influence of electromagnetic noise generated from the power supply board, and the power supply board can be prevented. Since the control board is not affected by the heat generated, the life of the control board can be extended.

以下、図面と共に本発明の一実施例について説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

図１は本発明になるガス充填装置の一実施例を示す正面からみた縦断面図である。図２は図１に示すガス充填装置の一部を断面で示す側面図である。
図１及び図２に示されるように、ガス充填装置１０は、例えば自動車の燃料タンク（被充填タンク）に都市ガスを所定圧力に圧縮した圧縮天然ガス（ＣＮＧ）あるいは燃料電池の燃料となる水素を供給するガス供給ステーションなどに設置されている。 FIG. 1 is a longitudinal sectional view as seen from the front showing one embodiment of a gas filling apparatus according to the present invention. FIG. 2 is a side view showing a part of the gas filling apparatus shown in FIG.
As shown in FIGS. 1 and 2, the gas filling device 10 includes, for example, compressed natural gas (CNG) obtained by compressing city gas to a predetermined pressure in a fuel tank (filled tank) of an automobile or hydrogen serving as fuel for a fuel cell. It is installed in a gas supply station that supplies electricity.

ガス充填装置１０は、図１の充填ホース２４,２６の２系統にガスを供給するためのガス充填系統１３を有する。また、筐体１２の前面１２ａ及び後面１２ｂには、充填量、充填圧力などの燃料充填に関する数値を表示する第１、第２の表示器１４，１６が設けられている。この第１、第２の表示器１４，１６は、筐体１２のフレーム２２に搭載された第１、第２の防爆容器１８，２０の表面に設けられている。また、筐体１２のフレーム１９には、異常発生時のアラームを発するブザー２１と、充填開始釦や充填停止釦などが配された操作部２２が取り付けられている。   The gas filling device 10 has a gas filling system 13 for supplying gas to the two systems of the filling hoses 24 and 26 of FIG. Further, the front surface 12a and the rear surface 12b of the housing 12 are provided with first and second indicators 14 and 16 for displaying numerical values relating to fuel filling such as filling amount and filling pressure. The first and second indicators 14 and 16 are provided on the surfaces of the first and second explosion-proof containers 18 and 20 mounted on the frame 22 of the housing 12. The frame 19 of the housing 12 is attached with a buzzer 21 for generating an alarm when an abnormality occurs and an operation unit 22 provided with a filling start button, a filling stop button, and the like.

第１、第２の防爆容器１８，２０は、夫々防爆強度を有する金属製の強固なケースであり、内部には、後述するように各種電気系統が配設された基板が収納されている。また、第１、第２の防爆容器１８，２０は、互いに筐体１２の中央付近に配置されており、裏面同士が対向するように背中合わせに取り付けられている。そして、防爆容器１８と２０との間は、電源及び各種信号を供給するためのケーブル２３ａ，２３ｂを介して電気的に接続されている。   Each of the first and second explosion-proof containers 18 and 20 is a strong metal case having explosion-proof strength, and a substrate on which various electric systems are disposed is housed inside. The first and second explosion-proof containers 18 and 20 are disposed near the center of the housing 12 and are attached back to back so that the back surfaces face each other. The explosion-proof containers 18 and 20 are electrically connected via cables 23a and 23b for supplying power and various signals.

ガス充填装置１０は、筐体１２の両側上部に充填ホース２４，２６が接続された継手３８，４０が設けられている。そして、充填ホース２４，２６の先端には、図示していない充填カプラが設けられている。   The gas filling device 10 is provided with joints 38 and 40 to which the filling hoses 24 and 26 are connected at upper portions on both sides of the housing 12. A filling coupler (not shown) is provided at the tip of the filling hoses 24 and 26.

また、図１に示されるように、筐体１２の下部には、ガス充填系統１３に配置された各機器に電気的に接続される複数の端子が設けられたターミナル装置３４と、防爆用安全保持装置３６とが筐体１２のフレーム３８に取り付けられている。このターミナル装置３４及び防爆用安全保持装置３６も防爆構造とされた容器に収納されている。   Further, as shown in FIG. 1, a terminal device 34 provided with a plurality of terminals electrically connected to each device arranged in the gas filling system 13 at the lower part of the housing 12, and an explosion-proof safety A holding device 36 is attached to the frame 38 of the housing 12. The terminal device 34 and the explosion-proof safety holding device 36 are also accommodated in a container having an explosion-proof structure.

さらに、筐体１２のフレーム４１には、後述する圧力計４２、調整弁４４、遮断弁４６、質量流量計４８が搭載されている。また、筐体１２の下部には、ライン用遮断弁５４Ａ，５４Ｂ、温度センサ５０などが配設されている。   Further, a pressure gauge 42, an adjustment valve 44, a shut-off valve 46, and a mass flow meter 48 described later are mounted on the frame 41 of the housing 12. In addition, line shut-off valves 54A and 54B, a temperature sensor 50, and the like are disposed at the lower portion of the housing 12.

ここで、防爆容器１８，２０の内部に収納された各基板について図３に示すブロック図を参照して説明する。   Here, each board | substrate accommodated in the inside of the explosion-proof containers 18 and 20 is demonstrated with reference to the block diagram shown in FIG.

図３に示されるように、第１の防爆容器１８には、表示器１４を駆動する表示基板２５と、各機器や各基板に電力を供給するインターフェイス基板２７と交流電力を直流電力に変換してインターフェイス基板２７に直流電力を供給する電源基板２８とからなる電力供給用基板２９が収納されている。また、第２の防爆容器２０には、表示器１６を駆動する表示基板３０と、表示基板２５，３０を制御すると共に、ガス充填系統に配置された各機器を制御する制御回路が設けられた制御基板３２とが収納されている。
そして、第２の防爆容器２０に収納された制御基板３２は、第１の防爆容器１８に収納された表示基板２５及びインターフェイス基板２７と、ケーブル２３ａ，２３ｂを介して電気的に接続されている。 As shown in FIG. 3, the first explosion-proof container 18 includes a display board 25 that drives the display 14, an interface board 27 that supplies power to each device and each board, and alternating current power to direct current power. A power supply board 29 including a power supply board 28 for supplying DC power to the interface board 27 is housed. Further, the second explosion-proof container 20 is provided with a display substrate 30 for driving the display device 16 and a control circuit for controlling the display substrates 25 and 30 and each device arranged in the gas filling system. The control board 32 is accommodated.
The control board 32 housed in the second explosion-proof container 20 is electrically connected to the display board 25 and the interface board 27 housed in the first explosion-proof container 18 via cables 23a and 23b. .

このように、本実施例では、防爆容器１８，２０が２つの容器に分割されているので、１個当たりの重量が従来の約半分になっており、大幅な軽量化が図られている。また、メンテナンス時には、防爆容器１８，２０を前面側と後面側から１個ずつ開いて点検、修理を行えるので、作業性が良くなり、メンテナンス作業を効率良く行えるといった利点も有している。例えば、メンテナンス時にインターフェイス基板２６または電源基板２８を点検する場合は、前面側から第１の防爆容器１８を開いて点検作業を行い、あるいは制御基板３２を点検する場合は、後面側から第２の防爆容器２０を開いて点検作業を行うことができる。   In this way, in this embodiment, the explosion-proof containers 18 and 20 are divided into two containers, so the weight per one is about half that of the conventional one, and a significant weight reduction is achieved. Further, at the time of maintenance, the explosion-proof containers 18 and 20 are opened one by one from the front side and the rear side, and can be inspected and repaired. Therefore, there is an advantage that workability is improved and maintenance work can be performed efficiently. For example, when inspecting the interface board 26 or the power supply board 28 at the time of maintenance, the first explosion-proof container 18 is opened from the front side and the inspection work is performed, or when inspecting the control board 32, the second side from the rear side. The explosion-proof container 20 can be opened for inspection work.

また、電源供給用基板２９と制御基板３２とを別々に防爆容器１８,２０に収納したことで、制御基板３２が電源供給用基板２９から発生する電磁ノイズの影響を受けて誤動作することを防止できると共に、電源供給用基板２９が発生する熱の影響を制御基板３２が受けなくなるので、制御基板３２の寿命を延ばすことができる。   Further, since the power supply board 29 and the control board 32 are separately housed in the explosion-proof containers 18 and 20, the control board 32 is prevented from malfunctioning due to the influence of electromagnetic noise generated from the power supply board 29. In addition, since the control board 32 is not affected by the heat generated by the power supply board 29, the life of the control board 32 can be extended.

さらには、防爆容器１８，２０が２つの容器に分割されて１個当たりの重量が軽減されているので、工場での組立工程での取付作業が容易に行えるため、組立作業効率をより高めることが可能になる。   Furthermore, since the explosion-proof containers 18 and 20 are divided into two containers and the weight per one is reduced, the mounting work can be easily performed in the assembly process at the factory, so that the assembly work efficiency is further increased. Is possible.

ここで、ガス充填系統を構成する各機器の配置例について図１及び図４を併せ参照して説明する。   Here, the example of arrangement | positioning of each apparatus which comprises a gas filling system is demonstrated with reference also to FIG.1 and FIG.4.

Further, the branch systems 13A and 13B branched into two systems are respectively pressure sensors 52A and 52B, line shutoff valves 54A and 54B, pressure gauges 56A and 56B, safety valves 58A and 58B, discharge valves 60A and 60B, and the above-described filling. The hoses 24 and 26 and the filling couplers 62A and 62B are provided.

これらの各機器のうち質量流量計４８、温度センサ５０、圧力センサ５２Ａ，５２Ｂによって計測された各計測値のデータは、前述したインターフェイス基板２６を介して制御基板３２に供給される。制御基板３２に搭載された制御回路(図示せず)は、これらの計測データに基づいて充填されるガスの圧力及び流量を調整するように調整弁４４の弁開度を制御する。   Among these devices, data of each measurement value measured by the mass flow meter 48, the temperature sensor 50, and the pressure sensors 52A and 52B is supplied to the control board 32 via the interface board 26 described above. A control circuit (not shown) mounted on the control board 32 controls the valve opening degree of the adjustment valve 44 so as to adjust the pressure and flow rate of the gas to be filled based on these measurement data.

尚、上記実施例では、都市ガスを圧縮した圧縮天然ガス（ＣＮＧ）を供給する場合を一例として挙げたが、これに限らず、例えばブタン、プロパン等のガス、あるいは燃料電池車で消費される水素ガスを供給するのにも適用できるのは勿論である。   In the above embodiment, the case where the compressed natural gas (CNG) obtained by compressing the city gas is given as an example. However, the present invention is not limited to this. Of course, the present invention can also be applied to supply hydrogen gas.

また、上記実施例では、自動車の燃料タンク１４に圧縮されたガスを充填する場合を一例として挙げたが、これに限らず、他の容器等に圧縮されたガスを供給する装置にも適用でき、あるいは単に圧縮されたガスを他の場所に給送するための管路途中に設置する構成の装置にも適用できるのは勿論である。   Further, in the above embodiment, the case where the compressed gas is filled in the fuel tank 14 of the automobile is given as an example. However, the present invention is not limited to this, and can be applied to an apparatus that supplies the compressed gas to other containers. Of course, the present invention can also be applied to an apparatus that is installed in the middle of a pipeline for supplying compressed gas to another place.
