Abstract

PURPOSE:To enable the supply of button to a button-fixing position in a proper posture, by transferring a button to the button-fixing position through a guide groove having a shape to force the button to take the proper posture. CONSTITUTION:A button is supplied from a hopper through a grooved track 4 to a guide 2 attached perpendicular to the grooved track 4, pushed with a pusher 6 sliding in the guide groove in the guide 2 and transferred to a receiving member 8 of a button-putting apparatus. The shape of the guide groove in the guide 2 is made to force the button to take a posture suitable for putting the button by the receiving member 8 in the course of pushing the button with the pusher 6 and transferring the button from the outlet of the track 4 to the receiving member 8.

Description

[Detailed description of the invention] Ru.

FIG. 1 shows a part of a button device mounting device having a guide groove 2 according to the present invention. Although not shown in FIG. 1, this device has a copper member such as a snap button in the storage space defined between the rotating hopper and the vertical surface of the machine frame, similar to the conventional button installation device. A track 4 that is housed and regulates the vertical direction of the button member through direction regulating grooves formed at equal intervals on the outer peripheral surface facing the machine frame side of the rotating hopper, and is then connected to the delivery port of the hopper. The button member is supplied to the guide groove 2 through the guide groove 2. The guide groove 2 in the device of the present invention is provided at right angles to the track 4 as in the conventional device, and the pusher member 6 slides inside the guide groove 2, but its cross-sectional shape is similar to the track 4. The left end when viewed in FIG. 2 from the position where 4 is joined, that is, the button mounting position is positioned to support the mold 8 and to hold the button member on the upper surface of the mold 8. Receiver member 12 (
(see FIG. 1) as three groove portions with different cross-sectional shapes: first, second, and conventional. The guide groove 2 of the present invention is intended for a mode in which a button member is fed from the track 4 into the conventional horizontal guide groove in a direction opposite to the original vertical direction. Therefore, here, as shown in FIG. 3, the button member 14 shown by the imaginary line is flown inside the racks 1 to 4 in an upside-down state, that is, in a state in which the button member 14 is in the original upward direction on the bottom 16 side of the track 4.

The three groove portions of the guide groove 2 configured according to the invention are shown in FIGS. 3 to 5. The first groove portion is formed so that its width in the transverse direction °C is slightly larger than the height of the button member 14, and its depth d is equal to the maximum diameter of the button member I4. The dimensions shall be sufficient to accommodate the portion. Therefore, the button member supplied to the first groove portion is in an upright state, that is, with its maximum diameter circumferential portion facing the groove bottom surface 16.
The groove is supplied with the upper and lower surfaces in contact with the side walls of the groove.

The second groove portion is formed in front of the first groove portion, that is, on the button mounting position side, and has a cross-sectional shape as shown in detail in FIG. 4. In this groove part, the button member 14
Each side wall 18 of the guide groove 2 on the side facing the upper surface and the side wall 20 on the side facing the lower surface are each formed by gradually widening toward the front from the end end having the width β of the first groove portion. As shown in FIG. 4, at approximately the intermediate position, β2,
Finally, at the end, as shown in FIG. 5, 12.
2. The dimension C2 is sufficient to accommodate the maximum diameter of the button member. FIG. 5 shows a conventional horizontal groove section connected to the second groove section.

Further, a dimension portion d of the side wall 18 above the depth d2 occupied by the pusher member 6 within the total depth dimension d of the guide groove 2;
, a contact means, that is, an overhanging portion 22 is shown on the inner side of the guide groove 2 in the transverse direction, for applying a rotational force that contacts the upper part of the button member 14 being pushed and thereby causes the button member to fall. It is formed to protrude like this. On the other hand, the formation of the widened portion is started from above the approximately middle height position of the side wall 20, as shown in FIG. The upper portion of the side wall thus defines a rotational guide surface 26 for the rotation of the button member from the beginning to the end of the widening, as also shown in FIG.

The conventional horizontal groove portion is formed in front of the second cross-sectional shape. The horizontal groove portion may have a conventional guide groove cross-sectional shape, and its transverse width dimension may also be the same as the final widening dimension of the second groove portion, ie, f22.

With this configuration, the button member 14 fed from the track 4 is first fed into the first groove portion in an upright state, as best shown in FIG. The button attachment is pushed into position, but upon passing through the second groove section, its upper section abuts against the overhanging section 22, thereby imparting a rotational force, and then the rotational guide surface 24 applies its rotational force. With the original lower surface abutting the bottom surface 26 of the guide groove 2 and thereby achieving the normal up-down direction, the button attachment can be pushed into position.

An alternative embodiment of the second groove portion is shown in FIG.

Here, of the total depth d of the guide groove 2, a dimension 64 portion below the lower end of the pusher member 6 is located downward in the original upper surface direction of the button member so that it can perform the same function as the overhanging portion 22. It is formed in a depressed state with an incline to the top.

As a result, the lower portion of the button member slides and rotates in a direction opposite to that of the overhanging portion 22, but with its original lower surface facing the groove bottom surface. Although the invention has been described with reference to specific examples, it should be remembered that many modifications may be made thereto.
