Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a component feeding device having an annular flange portion around the end of a cylindrical main portion. The above-mentioned parts are suitable for cases where button parts such as snap buttons, crimping buttons, or rivets are mainly handled.

(Prior Art) In this type of conventional component feeding device, the main part of the component fits into grooves formed at equal intervals on the inner edge of a truncated conical rotating drum, and by rotating the rotating drum, The parts were supplied to a chute (Japanese Unexamined Patent Publication No. 56-85407, hereinafter referred to as Conventional Example 1). In addition, as a part supply device for cylindrical or spherical parts, for example, the Utility Model Publication Publication No. 56-6828 (hereinafter referred to as Conventional Example 2)
) includes a parts storage section for storing parts, an inclined chute for dropping the parts in an inclined direction, and a part that can be slid up and down along the inclined chute, and that lifts the parts from the parts storage section and transfers them to the inclined chute. It is equipped with a blade that transfers and supplies parts in a line, and the upper end surface of the blade has an inclined surface where the inclined chute side is lower in the transverse direction, and the blade side is inclined so that the blade side is lower in the longitudinal direction. Presenting the device. Furthermore, Utility Model Publication No. 57-28832 (hereinafter referred to as Conventional Example 3) describes a hopper and a liftable line feeder for a cylindrical part having a curved circumferential surface, which is provided at an angle facing the hopper. In a line feeder comprising a reciprocating guide and a discharge chute provided in communication with the reciprocating guide, the reciprocating guide is installed with its operating direction inclined with respect to a vertical direction, and
The upper line stage is formed to be inclined toward the delivery chute side, and the line stage has a running surface having an inclination angle downward from the front surface of the reciprocating guide toward the inside of the plate thickness, and A receiving surface that intersects with the surface and has an inclination angle with respect to the plate surface direction of the reciprocating guide, and a mounting body that is installed above the receiving surface and on which the reciprocating guide slides. A line feeder consisting of a relief surface having an inclined angle is presented.

(Problem to be solved by the invention) In Conventional Example 1, when a part gets clogged in the groove with dust or work scraps, the part is not supplied to the chute and continues to rotate as the rotating drum rotates. , the chute will not be supplied for any length of time,
Furthermore, the jammed parts collide with the hopper frame on the hopper side, resulting in trouble in the rotation of the rotary drum and the inconvenience that parts cannot be smoothly supplied to the chute. In such a case,
The work efficiency was reduced and the work was extremely troublesome, as the rotating drum had to be shocked each time to shake out parts stuck in the grooves, or the machine had to temporarily stop operating to remove the parts. It was hot.

Furthermore, since this type of equipment uses a rotating drum, the equipment itself inevitably becomes large, and it is difficult to align the rotating drum and chute when transferring parts from the rotating drum to the chute. After setting the positions of the rotating drum and the chute, if the positions are not convenient, there is a problem in that in order to change the positions, the chute must be removed and the chute must be repositioned. Next, in Conventional Example 2, the horizontal upper end surface of the vertically moving blade is formed with an inclined surface that becomes lower toward the inclined chute side, so apart from cylindrical and spherical parts, the parts that are the object of the present invention In the case of a part that has an annular flange around the end of a cylindrical main part, a simple inclined surface is not enough to efficiently and reliably capture the part in a predetermined posture and hold the flange while moving it to the chute position. In addition, in the case of Conventional Example 3, the line stage formed at the upper end of the reciprocating guide that captures the part has a cross section perpendicular to the longitudinal direction of the inclined upper end. The lower running surface has a slight inclination α in the horizontal direction, and the receiving surface for the flat bottom of the cylindrical member has an inclination β relative to the plate surface direction of the reciprocating guide. Although the upper end surface is inclined toward the mounting body, it is different from the conventional example 1 in that the above-mentioned special inclined upper end surface cannot capture the parts or members that are the object of the present invention. There are many problems, such as the fact that the operating guide is reciprocated in an inclined state, and the mounting body itself, which is the sliding surface thereof, is also installed in an inclined manner. The purpose of the present invention is to efficiently and reliably align and connect parts having an annular flange portion around the end of a cylindrical main part such as a button from a hopper into which the parts are fed. By combining two units of this configuration, a single air cylinder is used to drive the supply of parts consisting of a combination of upper and lower parts, such as a caulking button, and the two supply units are connected to the button mounting device. By incorporating it, it will contribute to the creation of compact processing machines for fabrics, etc.
