[Detailed description of the invention] [Field of industrial application] The present invention is a button attaching machine for snap buttons, etc., which attaches the male body to each part of the male body consisting of a male part or a female part through clothing fabric. In particular, the present invention relates to a button component conveying device that guides each of the components from a component supply section to a conveyance section of a component mounting section.

[Conventional technology]

A conventional button parts conveying device includes a first chute that is connected to a component supply section exclusively for male components and has a groove for conveying male components, and a first chute that is connected to a component supply section exclusively for female components and has a groove for conveying female components. and a third chute connected to the first and second chute and having a groove for conveying a male component or a female component and extending to a conveyance path of the component mounting section. A switching means for guiding either the male part or the female part fed from the chute and the second chute to the third chute is arranged at the confluence part of the first chute, the second chute, and the third chute ( (Japanese Patent Publication No. 54-36850), or a male part is formed of a seat plate, a protruding ring protruding from the upper surface of the seat plate, and a circular protrusion protruding from the lower surface of the seat plate,
On the other hand, it is formed of a female component, a female cylinder, and a circular protrusion protruding from the lower surface of the female cylinder, and the circular protrusion of the male component and the female component loosely fit together, and the seat plate of the male component and the protrusion ring and It is known that the chute is provided with a groove into which the female cylinder of the female part loosely fits (Japanese Patent Publication No. 13443/1983).

[Problem that the invention attempts to solve]

However, in the case of the former button parts conveying device, since the first chute is dedicated to male parts and the second chute is dedicated to female parts, a switching means for guiding the male parts and female parts to the third chute is used. , which requires a large number of components, is complicated, and is expensive.

In addition, in the case of the latter button parts conveying device, although a groove is formed in the chute into which both the male and female parts loosely fit, the part where the male and female parts match in shape is a circular protrusion. Moreover, since the circular protrusion is formed to have a smaller diameter than the seat plate of the male component and the female cylinder of the female component and slides on the bottom of the groove, the stability of the male or female component during transportation is affected. There was a problem in that the chipped parts got stuck in the groove, making it impossible to transport the parts thereafter.

The present invention was devised in view of the above-mentioned problems with conventional button parts conveying devices. It is an object of the present invention to provide a button component conveying device with a simple structure that can feed the button components to a conveyance path.

[Means for solving problems]

According to the present invention, the above object is to provide a male part that integrally has a body part and a head part that protrudes from the body part and is smaller in diameter than the body part, and a body part that has the same diameter and the same height as the body part of the male part. In a button attaching machine equipped with a parts supply section that feeds female parts having a diameter to a chute, the chute is provided with a distance slightly larger than the distance between the outer surfaces of the bodies of the male and female parts, and a distance between the outer surfaces of the bodies of the male and female parts. A button characterized by having a first space slightly larger than the distance between the upper and lower surfaces, and a second space consisting of a groove from which the head of the male component projects or a recess for accommodating the head. This problem can be solved by using a parts transport device.

are the parts 11 and 2 fed through the chute 3.
1 to a component mounting section (not shown).

Note that the parts feeder 4 of the parts supply section 1 is equipped with a mechanism for feeding the male parts 11 and the female parts 21 to the chute 3 with the bodies 13 and 23 facing downward, but this mechanism is not adapted to the present invention. Since it is outside the scope of the above, its explanation will be omitted.

As shown in FIG. 2, the male component 11 includes an annular body 13 having a bulging portion 12 at its lower part, and an annular head 14 projecting upward from the center of this body 13.
It is equipped with both. Here, in the radial direction of the male component 11, the distance between the outer surfaces of the body 13 is D1.
and the distance between the outer surfaces of the head 14 is D2, and in the height direction of the male component 11, the body 13
The distance from the lower surface of the bulging portion 12 to the upper surface of the trunk 13 is defined as H1, and the distance from the upper surface of the trunk 13 to the upper surface of the head 14 is defined as H2.

As shown in FIG. 3, the female part 21 includes an annular body 23 having a bulge 22 below. Here, in the radial direction of the female part 21, the distance between the outer surfaces of the body part 23 is D3, and in the height direction of the female part 21, from the lower surface of the bulging part 22 of the body part 23 to the upper surface of the body part 23. Let the distance be H3. In addition, the respective distances D3 and H of the body part 23 of the female part 21
3 is approximately equal to the distances D1 and H1 corresponding to the body portions 13 of the male component 11, respectively.

As shown in FIGS. 2 and 3, the chute 3 includes a chute main body 32 in which a groove 31 is formed along the longitudinal direction, and a part of the opening of the groove 31 on both sides of the chute main body 32 in the width direction. It consists of a pair of lid members 33, 33 arranged so as to close the chute body 32 and fixedly fixed to the chute body 32 by bolts or the like at positions not shown.
A first space 34 is formed in the interior partitioned by both lid members 33, 33, and both lid members 3
A second space 34' is formed between 3 and 33.

The first space 34 is formed in a size such that the bodies 13 and 23 of the male component 11 and the female component 21 fit loosely, and the distance L between both inner surfaces of the chute body 32 is
2 is the distance D1, D between the outer surfaces of the trunk parts 13, 23.
