Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for moving a button by vibrating a feeder bowl having a spiral channel and supplying it from an outlet of the feeder bowl.

[0002]

[Prior Art]

 Usually, the button is attached to the front side of the body, but in recent years when the tastes are diversified, there are many demands to attach the button on the back. Conventionally, in order to cope with such a demand, a button discharged from a feeder bowl of a button supply device for selectively supplying only a front button using a selection plate having a plurality of triangular uneven edges is shown in FIG. It was turned inside out by passing it through a coil chute spring 8 that was tilted downstream and twisted 180 °.

[0003]

[Problems to be solved by the device]

 In the above button supply device, when the button Bo passes through the coil chute spring 8 twisted by 180 °, the shape inside the coil chute spring 8 may be deformed, and the deformation may cause the buttons to overlap with each other and become clogged. ..

An object of the present invention is to provide a button supply device that can smoothly supply a back button by simply modifying the conventional button supply device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the button feeder of the present invention is provided with a sorting plate having elongated holes provided in parallel with the side wall of the feeder bowl in the same plane as the channel of the feeder bowl. Two recesses are formed in the edge of the elongated hole on the upstream side of the feeder bowl center, and the plate surface width from that groove edge on the feeder bowl center side to the outer edge is set to be larger than 1/2 of the button diameter, and downstream of that. The distance from the edge of the plate surface on the center side of the feeder bowl to the side wall of the feeder bowl is set to be less than half the button diameter.

[0006]

[Work]

 In the button supply device configured as described above, when the button advances in the recessed position of the elongated hole, the button facing up does not fall on the selection plate having a width larger than 1/2 the diameter of the button. Move directly to. The button facing the back slides into the recess of the elongated hole due to the depression on the front side, and moves in an inclined state. When the button further advances, the distance from the side of the feeder bowl to the outer edge of the selection plate is set to be smaller than 1/2 the button diameter, so that the center of gravity of the button is higher than the edge of the feeder bowl. Located on the center side, it loses its balance and falls. Since the button facing the back is already slanted, the center of gravity of the button is inside the elongated hole rather than the selection plate, and it passes through without being dropped.

[0007]

【Example】

 A button supply device of the present invention will be described with reference to FIGS. 1 to 7.

As shown in FIG. 1, this button supply device 1 is arranged in front of a device 3 for individually forcibly parallel-feeding buttons to a sewing machine 2 with buttons, and as shown in FIG. 2 and FIG. The sorting plate 5 is provided in front of the exit of the feeder bowl 4 having the channel 41.

The sorting plate 5 is provided so that its position can be adjusted in the diameter direction of the side wall 42 of the feeder bowl 4, and is fixed to the feeder bowl 4 by a screw 6. The position is adjusted by turning the knob 7. The channel floor surface 41a of the portion where the sorting plate 5 is provided is slightly lower than other portions so that the button Bo does not descend from the elongated hole 51 described later, but the upper surface of the sorting plate 5 is the same as that of the feeder bowl 4. It has the same height as the surface of the channel 41.

The sorting plate 5 is provided with an elongated hole 51 in parallel with the side wall 42 of the feeder bowl 4, and a triangular notch recess 52 is provided on the upstream side of the elongated hole 51 on the center side of the feeder bowl. Are formed in succession. The plate surface width La from the groove end on the feeder bowl center side to the outer edge of the portion A where the notch recess 52 is formed is 1 / the diameter of the button Bo as shown in FIGS. 4 (b) and 5 (b). The width of the plate surface on the feeder bowl center side of the portion B on the downstream side is slightly narrower than that of No. 2 and is further narrowed as shown in FIGS. The distance Lb from the bowl side wall 42 is set to be slightly smaller than 1/2 of the diameter of the button Bo.

As shown in FIG. 2 and FIGS. 4 to 7B, the button Bo has a hollow center at the front side and a flat back side.

[0012] When such a button Bo goes through the portion A of Fig. 3, in the case of the button Bo facing the front, the bottom is flat, and therefore, as shown in Fig. 4, the diameter of the button Bo is 1 It moves on the sorting plate 5 having a width La slightly larger than / 2 without dropping. In the case of the button Bo facing the back side, due to the depression on the front side, as shown in FIG. 5, the button Bo slides into the notch recess 52 and moves in an inclined state.

When the button Bo is further advanced from the portion A of FIG. 3 to move the portion B, the button Bo faces the front. In the case of the button Bo, the distance Lb from the feeder bowl side wall 42 to the outer edge of the sorting plate 5 is Since it is set to be slightly smaller than 1/2 of the diameter of the button Bo, the center of gravity of the button Bo is located on the center side of the feeder bowl outside the edge of the sorting plate 5 as shown in FIG. To do. In the case of the button Bo facing the back, it has already been slanted into the elongated hole 51 at the portion A, so that the center of gravity of the button Bo is smaller than that of the selection plate 5 as shown in FIG. It is inside 51 and can pass through without dropping. In this way it is possible to supply only the back-facing buttons. By operating the knob 7, the position of the elongated hole 51 with respect to the side wall 42 of the feeder bowl can be changed according to the size of the button.

[0014]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects.

That is, by attaching a simple selection plate, only the button facing the back can be reliably and smoothly supplied. Therefore, in the case of using the coil chute spring, the twist can be eliminated, and the clogging of the button does not occur. The parallel forced feed type has made it possible to supply back buttons, which was previously impossible.
