Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a button attachment device, and more particularly to a jaw member included in the button holder.

[Description of Prior Art]

Conventionally, various buttons are attached to the cloth by using a hopper type button attaching apparatus shown by 1 in FIG. The device generally has a button holder 1 for receiving each button member supplied from a hopper 3, 5 through a guide groove 7, 9 respectively and holding it above and below a mounting position.
It has 1 and 13. In particular, the lower button holder 13 is opened in a direction orthogonal to the guide groove 9 to receive the button member, and after that, a pair of jaw members (for holding the button member on the center of its mounting position until the button is mounted). (Not shown) is included. FIG. 8 illustrates one jaw member 15 of the pair of jaw members. The jaw member 15 typically has a semi-circular arc portion 17 for holding a button member,
A tapered portion 19 and a straight portion 21 which are inlet portions for receiving the button member are formed. The jaw member having such a shape is a modified button member as shown in FIGS. 15 and 16.
For handling 23, generally, the circular arc portion 17 is made larger, that is, longer. However, this inevitably narrows the width w (see FIG. 14) of the straight portion 21, so that when the deformed button member is introduced between the pair of jaw members, the maximum diameter portion 25 of the deformed button member is changed to the straight portion 21. If the jaw member comes into contact with the jaw member, the opening of the jaw member to the left and right becomes excessive, and the front portion of the button member that has entered the jaw comes off from the circular arc portion 17 of the jaw member. Occurs.

[Purpose of device]

Therefore, an object of the present invention is to provide a jaw member capable of holding a deformed button member at the central position of its mounting position.

[Constitution and effect of device]

According to the present invention, there is provided a pair of jaw members included in a button holder for holding a button member above or below a mounting position in a button mounting device, the jaw member having a maximum diameter when receiving the button member. The movable member is configured to come into contact with the portion and thereby open to receive the button member, and the circular arc portion for holding the received button member, and the movable member is opened to release the button member when the button is attached. There is provided the jaw member, characterized in that it has a two-member construction consisting of a holding member adapted to open together with the member.

The portion of the movable member that abuts the maximum diameter portion of the button member is a tapered surface that inclines toward the center of the button member mounting position, and the rear end of the movable member is a spring member that causes the jaw member to close. It is configured to be biased in the same direction.

The jaw member of the present invention has the above-described structure, and when the button member is received between the pair of jaw members, not only the entire jaw member but only the movable member is always opened, and the groove for receiving the outer peripheral portion of the button member is formed. Since the arc portion that constitutes it does not open, even when receiving a deformed button having a shape far from the circular shape, the maximum diameter portion also always opens only the movable member, so the front portion thereof may come off from the groove. Disappears.

With the two-member configuration, when the movable member is opened, a guide groove for guiding the button member to the circular arc portion is created in a portion up to the circular arc portion, whereby a button including the deformed button member is created. The holding of the member in the proper position is further facilitated.

[Explanation of Example]

The present invention will be described in detail with reference to FIGS. FIG. 1 illustrates a jaw member 10 according to the present invention. Unlike the conventional jaw member, the jaw member 10 has a holding member 16 having an arc portion 12 and a straight portion 14 (see FIG. 4) for holding the received button member.
And a taper portion 18 which serves as an entrance portion for receiving the button member.
And a movable part 20 in which the above is formed.

The movable member 20 is positioned on the front side with respect to the direction in which the button member is introduced into the jaw member indicated by the arrow a, and
It is movable in each direction for opening and closing the button member to be introduced, as shown by an arrow b, in a partially slidable state with respect to the holding member 16. A spring means is provided behind the movable member 20.
A notched portion 24 for receiving one end of 22 (see FIG. 6) is formed, and the movable member 20 is normally biased in the direction of arrow c by the spring means 22.

FIG. 3 illustrates a side view of the movable member 20 in an open state. As shown, the portion 26 including the tapered portion 18 of the movable member 20 is formed thinner than the other portions, and is formed in a wedge shape as shown in FIG. A first flat surface 28 and a second flat surface are provided above and below the root portion.
30 are formed respectively. On the other hand, in the portion of the holding member 16 corresponding to the wedge-shaped portion 26, a groove 32 is formed for receiving the wedge-shaped portion 26 and allowing the portion 26 to pass therethrough as the movable member 20 opens and closes. Then, the first flat surface 28 of the thin plate portions 34 and 36 (see FIG. 1) constituting each side of the groove 32 is formed.
A third flat surface 38 and a fourth flat surface 40 are formed at positions corresponding to the second flat surface 30 and the second flat surface 30, respectively. Therefore, the movable member 20 is prevented from further moving in the direction of the arrow b by contacting these surfaces with each other.

Further, the groove 32 of the holding member 16 acts as a guide groove when the button member is introduced into the circular arc portion when the movable member 20 is opened, and this groove is horizontal to the circular arc portion 12 of the holding member 16. The introduction of the button member in the state is promoted.

The jaw member of the present invention operates as follows in a series of mounting operations for any button member, including a modified button member as shown in FIGS.

First, a button member (not shown) is introduced from the direction indicated by arrow a in FIGS. 1 and 4. The maximum diameter portion of the button member comes into contact with the tapered portion 18 of the movable member 20 and is further pushed in the direction of arrow a, whereby the movable member opens in the direction of arrow d. The button member is then a wedge-shaped part with the largest diameter.
The arc portion 12 is entered by crossing the tip portion 42 of 26 and the straight portion 14 of the retaining member 16. At this time, the holding member 16
Remains stationary while the movable member 20 returns to the closed condition shown in FIG.

As described above, according to the jaw member of the present invention, when the button member is received and held, only the movable member 20 is opened, and when the button member is attached, the entire jaw member including the movable member 20 is opened. It solves the drawbacks of technology and achieves the effects mentioned above.

Although the present invention has been described with reference to specific examples, it should be understood that many modifications may be made within the present invention.
