Feeder and part feeding device

Abstract

An objective of the invention is to improve supply speed of parts. A feeder has a component holding device (61) and a rotary vibration machine that makes the periphery of the axis of the component holding device rotate and vibrate. The component holding device (61) has an inner bottom (62) and an inner peripheral portion (63). The inner bottom (62) has a cone frustum shaped inner surface (62a), and has component guide grooves (62b, 62c, 62d, 62e, 62f, 62g) formed on the inner surface and extending toward an outer peripheral side. The inner peripheral portion (63) has an inverted truncated coneinner surface (63a) and a component conveying path (63b) which is formed on the inner surface and gradually rises from a landing port (63s) located at a boundary position of the inner bottom portion.The component guide grooves guides the components in a manner that the components are limited in a standard posture.

Description

technical field [0001] The present invention relates to a feeder and a parts supply device, and more particularly to a parts guide structure of a parts container constituting the feeder. Background technique [0002] Normally, as shown in FIG. 6( a ) and FIG. 6( b ), the feeder 4 has a structure in which a bowl-shaped parts container 41 is mounted on a rotary vibrator 40 . The parts holder 41 has an inner bottom 42 and an inner peripheral part 43, wherein the inner bottom 42 has a truncated conical inner surface 42a capable of storing a large number of parts and moving the parts to the outer peripheral side, and the inner peripheral part 43 has a An inverted conical inner surface 43 a of the outer periphery of the bottom 42 . The inner peripheral portion 43 is provided with a parts conveyance path 43b formed in a spiral shape around the axis. When the above-mentioned parts container 41 receives the vibration along the rotation direction around the axis and obliquely upward...

Problems solved by technology

In such a setting, although the parts are initially conveyed with a high conveying density, a large number of parts are conveyed in a disorderly overlapping posture, so many parts are excluded in the subsequent sorting process, so that the final part P is When conveyed in a line in a standard posture, it becomes a conveying form in which there are many gaps in the conveying direction between the parts P, and the conveying density of the parts is often greatly reduced.
