Air supply valve and component transportation device

Abstract

The present invention provides an air supply valve provided with an air guide channel for guiding air, a guide opening of the channel faces a valve cylinder inwards, a valve body of a closing part composed of the guide opening is provided in the valve cylinder, an air guide out channel facing the guide out opening in the valve cylinder is provided, and a piezoelectric execution mechanism driving the valve body to execute opening / closing action of the guide opening is provided. the invention is characterized separately arranging air path communicating space between the guide opening and the guide out opening outsides and the guide channel and the air guide out channel when the valve is opened. Thereby realizing miniaturization of the air supply valve and reducing delay of starting and stopping spray air flow.

Description

technical field [0001] The present invention relates to a gas supply valve and a component conveying device, and more particularly, to a structure of a gas supply valve suitable for controlling the state of gas supply in order to selectively perform gas blowing for conveying component sorting. Background technique [0002] Generally, in a parts conveying apparatus (part supplying apparatus) such as a parts feeder, it is required to convey a plurality of parts in a high-speed and controlled posture, but in such a parts conveying apparatus, in order to eliminate structural defects from the parts conveying path Parts, parts that are not in a normal posture, or to convert a part that is not in a normal posture into a normal posture, gas is selectively blown onto the parts on the part conveying passage. [0003] When supplying gas to the parts sorting unit in the above-mentioned parts conveying device, a gas supply valve that needs to operate at a high speed in order to sup...

Problems solved by technology

However, if the operating stroke of the piezoelectric actuator and the cross-sectional area of ​​the internal space of the valve are increased, the valve structure itself will be enlarged. In addition, when the pressure on the supply side is increased, the internal space of the valve (introduction opening when the valve is opened) Negative pressure is generated in the space between the outlet opening and the outlet opening), and the driving load of the piezoelectric actuator increases. Therefore, in any case, the size of the gas supply valve and the increase in power consumption are caused. At the same time, there is a residual pressure in the valve internal space. Makes the start and stop of gas blowing on the part delivery channel prone to hysteresis
