BACKGROUND OF THE INVENTION 1. Field of the Invention The invention of the present application relates to a slanted conveyor type part feeder in which various long parts forming machine elements such as pins, shafts, bolts and the like are aligned and sequentially supplied to the next step. .

[0002]

2. Description of the Related Art Conventionally, a vibrating parts feeder has been used as a parts feeder for feeding various long parts such as pins, shafts, bolts and the like, which are machine elements, in an aligned state and sequentially supplied to the next process. . However, since this type of parts feeder aligns the parts while applying vibration, the noise generated by the airframe and the contact between the airframe and the parts is large, and the energy consumption is large.
The spiral chute is heavily worn, maintenance is expensive, and restoration is difficult.

As an alternative to such a vibrating parts feeder, a slender bottom part having a width approximately corresponding to the diameter of the parts is provided at the lower ends of the inclined side walls of the parts storage container (hopper). An inclined transfer type part feeder has been proposed in which a conveyor running along an ascending slope conveys parts by friction while aligning the parts in the bottom part (see Japanese Patent Laid-Open No. 7-010254). This is also equipped with a rotating disk type excluding means for excluding non-aligned parts by a magnet.

However, in this type of parts feeder, since the bottoms for aligning the parts are fixedly provided at the lower ends of the inclined side walls of the hopper, different parts can be aligned and conveyed. Since a rotating disk with multiple magnets on the outer circumference is used to eliminate difficult, misaligned parts, the scraper separates misaligned parts adhering to the magnets, which still consumes a large amount of energy, and uses a hopper. Since it is dropped inside, there is a problem that noise is easily generated.
