Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component feeding device for a semicircular cone-shaped component, such as a valve tip or a valve tip-shaped component, in a vibrating component feeder.

In general, a vibrating parts feeder is also called a parts feeder.In a spiral parts feeder, a spiral track is formed inside a bowl-shaped ball, and the parts on the track are transferred by receiving torsional vibrations. It is often required to supply parts to the next process with the parts in a desired orientation. For such cases, various types of conveying devices have been developed depending on the shape of the parts to be supplied. Or, a feeding device for feeding the valve controller 1 in the orientation shown in FIG. 1 in the direction of arrow A or in the opposite direction has not yet been developed. Alternatively, conventionally developed sorting devices cannot provide a reliable effect.

The present invention has been made in view of the above-mentioned points, and is a part of a valve cotter or a valve cotter-like part in a vibrating parts feeder that can reliably maintain the valve cotter or another cotter-like part in the above-mentioned desired posture and supply it to the next process. The purpose is to provide a sorting device. According to the present invention, in a parts sorting device for semicircular frustum-shaped parts in a vibrating parts supply machine, which applies vibration to a transport track to transport the parts on the track, It has a width slightly larger than the thickness of the semicircular cone-shaped part to be transferred to the transport surface of the truck, a length slightly larger than the length of the part, and a taper angle of the part with respect to the transport direction of the part. The conveying surface of the conveying track is inclined downwardly toward the side wall portion, and the opening is formed with a curved outer surface facing upward and a longitudinal direction thereof being in the conveying direction. When one end of a semicircular cone-shaped part in a predetermined direction is brought into contact with the side wall part, the other end of the part fits into the part, and the outer circumferential curved surface is directed upward. The component, which is oriented in the predetermined direction in the length direction, is inverted by fitting the other end into the opening, and is received with the outer peripheral curved surface downward in the transfer path below the transfer surface. This is achieved by a parts sorting device for semicircular frustum-shaped parts in a vibrating parts feeder, characterized in that the parts are transported in the predetermined direction in the length direction of the transport path.
