Description

  The present invention provides a normal pressure tool that is driven by compressed air pressure in the normal pressure region, and a high pressure tool that is driven by compressed air pressure in a higher pressure region, depending on the tool used and the work content. It is related with the compressed air supply system by the auxiliary | assistant tank which can supply the compressed air of an appropriate pressure area | region to each air drive tool of this.

At present, there are used air-driven tools for normal pressure used in a normal pressure region where the working air pressure is, for example, 8 kg / cm ² or less, and high pressure used in a high pressure region where the working pressure region is higher than these. A compressed air supply system that supplies compressed air for driving to a tool of this type is configured by an air compressor that generates compressed air in a high pressure region of, for example, 30 kg / cm ² and stores the compressed air in an air tank.

  In an air compressor that can supply compressed air to both high-pressure and normal-pressure tools, at least one compressed air take-out device dedicated to high pressure and one compressed air take-out device dedicated to normal pressure are installed. In addition, each compressed air take-out device is connected to a pressure regulator and a tool side for reducing the high-pressure compressed air generated in the air compressor and stored in the air tank to the high pressure and normal pressure areas. A socket to which a hose plug is attached is provided. For each normal pressure and high pressure dedicated tool, a compressed air supply source is used so that the normal pressure tool is not connected to the high pressure compressed air take-out device and compressed air in the high pressure range is not supplied to the normal pressure tool. The plugs attached to the rear end of the tool connected to each other through the air hose have a dedicated shape in order to prevent erroneous connection.

  In addition, the air compressor for using these pneumatically driven tools has been reduced in size and weight so that it can be easily transported to the work site, moved to the installation location within the site, and the like. The capacity of the air tank provided in is set small. Therefore, tools that consume a relatively large amount of compressed air cannot be used continuously. Therefore, it is necessary to connect an auxiliary tank to the air tank of the air compressor to increase the amount of compressed air stored. Has been done. In the conventional auxiliary tank, the inside of the air tank of the air compressor and the inside of the auxiliary tank are simply connected by a dedicated hose or the like, and each tool is connected to each tool via a pressure regulator installed in the air compressor. Compressed air is supplied through each dedicated air hose.

  The conventional auxiliary tank simply increases the capacity of the air tank by connecting it to the air tank of the air compressor with an air hose. This is done via an air hose connected to the device. For this reason, when moving the work place, the air compressor main body and the auxiliary tank must be moved together, and workability is impaired. In addition, when two tools are used at a distance from each other, an auxiliary tank is connected to the air compressor body, and then compressed air is supplied from the compressed air take-out device of the air compressor body to each tool via an air hose. When adjusting the working pressure of each tool, it was troublesome to reach the air compressor and operate the pressure regulator of the compressed air take-out device of the air compressor. .
