Description

【0001】
【発明の属する技術分野】
本発明は圧縮機を用いて圧縮した空気を分離した2つのエアタンクに蓄積し、打込機などの空気式工具へそれぞれ供給するエア圧縮装置に関するものである。
【0002】
【従来の技術】
従来のエア圧縮装置は、圧縮機を用いて圧縮した空気を1つ又は2つ以上連結したエアタンクに蓄積し、エアタンクから打込機等の空気式工具に空気を供給していた。圧縮機から空気工具に接続する継手までの間において、エア漏れや故障などが生じた場合、エア圧縮装置を修理完了するまでの間、使用できなくなるため、その間にエア圧縮装置を使用したい使用者には不便であった。
【0003】
【発明が解決しようとする課題】
従来のエア圧縮装置は上記の如く、エアタンクが1つ又は2つ以上連結されたものであった場合、エアタンク又はエアタンクより継手側に接続された減圧弁、安全弁、圧力計、継手等の空気流路においてエア漏れや故障等が生じた時にエア圧縮装置を修理する必要があるため、修理完了までの間、エア圧縮装置を使用することが出来なくなる。
【0004】
本発明は、圧縮機から流れる圧縮空気を2つに分離、一方のエアタンク側が故障した場合、もう一方のエアタンクのみで打込機などの空気式工具への供給を可能とすることを目的とする。
【0005】
【課題を解決するための手段】
上記目的は、打込機などの空気式工具の空気供給源であって、圧縮機を用いて圧縮した空気を2つに分離した空気流路ごとに夫々エアタンを設け、前記圧縮機と前記エアタンク間にそれぞれ減圧弁を設けることによって達成される。
【0006】
【発明の実施の形態】
以下、本発明の一実施形態を示す図1により説明する。
【0007】
図1において、エア圧縮装置1は、電動機3を動力源として、圧縮機4により外部からの空気を吸入エアフィルター2から吸い込み、該空気を圧縮加圧する。加圧された圧縮空気は、2つの空気流路に分離して第1エアタンク7と第2エアタンク13に流れる。
【0008】
なお、圧縮機4と第1エアタンク7の間には第1エアタンク7への圧縮空気の流れを遮断可能な減圧弁6と、圧縮機4と第2エアタンク13の間には第2エアタンク13への圧縮空気の流れを遮断可能な減圧弁12を設ける。更にエアタンク内の圧縮空気の圧力が所定の圧力まで低くなると電動機3が起動し、所定の高圧になると電動機3が停止する働きをさせる圧力スイッチ5を圧縮機4と2つの減圧弁6、減圧弁12との間に設ける。
【0009】
2つに分離した空気流路の内、第1エアタンク7側に流れる空気流路は、第1エアタンク7内の圧縮空気の圧力が所定圧力以上になると圧縮空気を外部に噴出する安全弁8と、第1エアタンク7から流れる圧縮空気の圧力を調整する減圧弁9と、減圧弁9と継手11との間の空気圧を読み取る圧力計10と、図示しない打込機等の空気式工具に接続する継手11から構成され、打込機等の空気式工具に空気を供給する。
【0010】
もう1つの空気流路である第2エアタンク13側の空気流路は、第2エアタンク13内の圧縮空気の圧力が所定圧力以上になると圧縮空気を外部に噴出する安全弁14と、第2エアタンク13から流れる圧縮空気の圧力を調整する減圧弁15と、減圧弁15と継手17との間の空気圧を読み取る圧力計16と、図示しない打込機等の空気式工具に接続する継手17から構成され、打込機等の空気式工具に空気を供給する。
【0011】
上記の構成において、通常エア圧縮装置1を使用する時には、減圧弁6と減圧弁12はエアタンク内の圧縮空気の所定圧力以上に設定する。しかし、一方の空気流路すなわちエアタンクからの継手の間においてエア漏れ、故障等が生じた場合、エア圧縮装置の使用を止め、該エアタンクに圧縮空気を流さないよう、エア漏れ、故障等が生じた側の空気流路に設けてある減圧弁(減圧弁6又は減圧弁12)を使用者が閉じる。その後も、エア漏れ、故障等が生じていない方の空気流路により、打込機等の空気式工具に空気を供給することができる。
【0012】
【発明の効果】
以上説明したように本発明によれば、一方のエアタンクから継手の間におけるエア漏れ、故障等が生じた場合、もう一方のエアタンクのみですぐに打込機等の空気工具に空気を供給することができる。よって、エア漏れ、故障等が生じた後もすぐに引き続き打込機等の空気工具の作業を行うことができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air compression device that accumulates air compressed using a compressor in two separated air tanks and supplies the air to a pneumatic tool such as a driving machine.
[0002]
[Prior art]
A conventional air compression device accumulates air compressed using a compressor in one or more connected air tanks, and supplies air from the air tank to a pneumatic tool such as a driving machine. If air leaks or malfunctions occur between the compressor and the joint connected to the pneumatic tool, the air compressor cannot be used until repair is completed, so users who want to use the air compressor during that time Was inconvenient.
[0003]
[Problems to be solved by the invention]
As described above, when one or two or more air tanks are connected to the conventional air compression device, the air flow from the air tank or a pressure reducing valve, a safety valve, a pressure gauge, a joint, or the like connected to the joint side from the air tank is reduced. Since it is necessary to repair the air compression device when an air leak or a failure occurs on the road, the air compression device cannot be used until the repair is completed.
[0004]
SUMMARY OF THE INVENTION It is an object of the present invention to separate compressed air flowing from a compressor into two parts, and to supply air to a pneumatic tool such as a driving machine using only the other air tank when one air tank side fails. .
[0005]
[Means for Solving the Problems]
The above object is to provide an air supply source for a pneumatic tool such as a driving machine, wherein an air tank is provided for each of two air passages in which air compressed using a compressor is separated into two, and the compressor and the air tank are provided. This is achieved by providing a pressure reducing valve between them.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIG.
[0007]
In FIG. 1, an air compressor 1 uses a motor 3 as a power source to draw air from the outside from a suction air filter 2 by a compressor 4 and compresses and pressurizes the air. The pressurized compressed air is separated into two air flow paths and flows to the first air tank 7 and the second air tank 13.
[0008]
In addition, between the compressor 4 and the first air tank 7, a pressure reducing valve 6 that can shut off the flow of compressed air to the first air tank 7, and between the compressor 4 and the second air tank 13 to the second air tank 13. A pressure reducing valve 12 capable of blocking the flow of compressed air is provided. Further, when the pressure of the compressed air in the air tank decreases to a predetermined pressure, the electric motor 3 starts, and when the pressure of the compressed air reaches a predetermined high pressure, the motor 3 is stopped. 12 is provided.
[0009]
Among the two separated air flow paths, an air flow path flowing to the first air tank 7 side includes a safety valve 8 that jets out compressed air to the outside when the pressure of the compressed air in the first air tank 7 becomes equal to or higher than a predetermined pressure; A pressure reducing valve 9 for adjusting the pressure of the compressed air flowing from the first air tank 7, a pressure gauge 10 for reading the air pressure between the pressure reducing valve 9 and the joint 11, and a joint connected to a pneumatic tool such as a driving machine (not shown). 11 to supply air to a pneumatic tool such as a driving machine.
[0010]
An air flow path on the side of the second air tank 13, which is another air flow path, includes a safety valve 14 for injecting compressed air to the outside when the pressure of the compressed air in the second air tank 13 exceeds a predetermined pressure; A pressure gauge 16 for reading the air pressure between the pressure reducing valve 15 and the joint 17, and a joint 17 connected to a pneumatic tool such as a driving machine (not shown). Supply air to pneumatic tools such as driving tools.
[0011]
In the above configuration, when the normal air compressor 1 is used, the pressure reducing valve 6 and the pressure reducing valve 12 are set to be equal to or higher than a predetermined pressure of the compressed air in the air tank. However, if air leaks or failures occur in one of the air flow paths, that is, between the joints from the air tank, the use of the air compressor is stopped, and air leaks or failures occur so that compressed air does not flow into the air tank. The user closes the pressure reducing valve (the pressure reducing valve 6 or the pressure reducing valve 12) provided in the air flow path on the other side. After that, air can be supplied to a pneumatic tool such as a driving machine through the air flow path in which no air leakage, failure, or the like has occurred.
[0012]
【The invention's effect】
As described above, according to the present invention, when air leakage from one of the air tanks to the joint, a failure, or the like occurs, air is immediately supplied to a pneumatic tool such as a driving machine using only the other air tank. Can be. Therefore, immediately after an air leak, a failure, or the like occurs, the operation of the pneumatic tool such as the driving machine can be continuously performed.
