The present invention relates to a button automatic feeding device, and more particularly, to a button automatic feeding device for automatically feeding a button so that the position of the hole of the circular button is exactly matched to the position of the pin of the button feeding device.

In general, a button feeder for precisely positioning a button at a predetermined position in order to attach a button to a cloth in a coating factory, and a needle of a sewing machine to be exactly positioned with a button hole is transferred by matching a pin to a button hole in a circular button.

1 is a schematic diagram of a conventional button automatic feeding device.

Referring to Figure 1, in order to exactly match the button to the pin of the button feeder in the prior art by transporting the vibretta (2) in the box containing the button (1) and then sequentially transfer the buttons, guide both ends of the button with a guide The position was transferred by pinching.

In addition, if the size of the button to be transported is different, the guide must be replaced frequently to match the size of the button. In the process of transporting the same size button, the size of the button is not constant. There were three problems.

The present applicant has filed the Republic of Korea Utility Model Registration No. 20-0143294, the prior patent is a device for automatically supplying a button.

2 is a main view of a conventional button position correction device.

Referring to FIG. 2, a cam groove 12 is formed at a point where the center point is axially divided into three parts of the rotatable circular plate 10, and the cam groove 12 slides on the rail 22 and the rotor 32 in front of the cam groove 12. The protrusions 24 of the sliders installed therein are inserted.

One of the sliders 21a of the sliders is connected to the cam 42 that is rotated by the motor 40 with a damper 48, and a rubber roller 26 is formed below the rotor 32. It allows selective contact with the outer surface of the circular button 70.

In addition, the lower end of the circular plate 10 is provided with a rotary ball 30 that is rotated by the motor 40, the lower portion of the rotary ball 30 is formed with at least one protrusion is formed in the hole of the button 70 and It is formed to have the same distance.

The prior art configured as described above is guided by the vibration of the vibretta from the button box containing the plurality of buttons 70 and moved one by one in a row, and the moved button 70 is placed on the guide plate 81 in the slider. It is conveyed between three rubber rollers 26 provided at the tip of 21a.

In this state, when the motor 40 on one side is driven, the cam 42 connected to the motor shaft rotates.

Therefore, the slider 21a in which the protrusion 24 fitted in the cam groove 12 is fitted is guided to the rail 22 by the cam 42 and advanced.

At this time, as one slider moves forward in a straight line, the protrusions 24 of the slider 21 are fitted into the cam grooves 12 of the upper circular plate 10, and thus the circular plate 10 is centered on the central axis 15. Will rotate.

Accordingly, the three

sliders

21a, 21b, and 21c into which the protrusions 24 are inserted into the cam grooves 12 of the circular plate 10 are all advanced, and the lower rubber rollers 26 are formed of the circular buttons 70. Since the circular button 70 is moved forward in the direction of contact with the outer surface is moved to the set point where the three sliders (21a, 21b, 21c) are gathered, the center is held constant.

9 to 11 are views showing three examples in which the operation of the "button closure member" is varied according to the size of the button in the distribution apparatus of the present invention described in FIG.

As shown in Fig. 8, the button closure member 6 is a means for controlling the position so that the buttons to be conveyed one by one by the guide means 2 and the button conveying means 4 can be put in place.

The button closure member 6 is composed of a first stepped jaw 61 positioned at the front end of the guide means 2, and a second stepped 62 installed at a predetermined distance from the first stepped jaw 61. The first stepped jaw 61 and the second stepped jaw 62 are advanced back and forth by the forward-backward shifting device 63, so as to be mutually operated.

In the above-described alternating operation, when the first step 61 is drawn out, the second step 62 is retracted, and when the first step 61 is retracted, the second step 62 is withdrawn.

The forward and backward device 63 which causes the forward and backward operation of the first and second stepped

portions

61 and 62 is preferably a hydraulic or pneumatic cylinder, and the forward and backward device 63 has a shaft 64 having a predetermined length. It is coupled to the position is simultaneously adjusted according to the diameter size of the circular button (200).

In addition, the distance between the first and

second steps

61 and 62 may be changed according to the diameter of the button.

That is, as shown in FIG. 9, the second step 62 of the button closure member 6 may be moved by a predetermined deviation adjusting means, whereby the distance from the first step 61 is closer or farther away. Can be adjusted to

The distance adjusting amount of the second step 62 is determined according to the diameter of the circular button 200.

The deviation adjusting means is selected from a stamping motor 600 for moving the second step 62 under the control of the controller or a handle 500 for moving the second step 62 by manual rotation operation.

9 to 11, the operation of the button closure member 6 will be described.

The diameter size of the circular button 200 is in the order of Figure 9 <Figure 10 <Figure 11.

Referring to the right side of FIG. 9 and FIG. 15, the first stepped portion 61 is drawn out to block the front of the guide means 2, and when the circular button 200 advances on the guard 24, the circular button is reached. The front end of the 200 is in contact with the first stepped portion 61 and is in the first correct position P1.

Subsequently, when the push rod 42 presses the circular button 200, the first step 61 is retracted, and at the same time, the second step 62 is pulled out.

Therefore, the push rod 42 moves the circular button 200 forward (in the left direction of FIG. 9) while advancing.

Thereafter, the circular button 200 is placed at the position where the pin E2 of the button transfer device E is waiting by the second step 62 (this is referred to as 'second correct position P2'). (See FIG. 18).

Especially important is to preset the position of the second step 62 so that the center of the circular button 200 can be placed in the center of the pin E2 of the button transfer device E.

For example, if the diameter of the circular button 200 is 10 mm, the second step 62 is 5 mm to the left from the center of the pin E2 of the button transfer device E by operating the deviation adjusting means (circular button diameter ( It is set by moving the distance (L) of 1/2 of L).

Therefore, when the circular button 200 is placed at the center of the pin E2 of the button transfer device E, the end thereof may be in close contact with the second stepped portion 62.

Then, the first and second rollers 81 and 81 'of the rear support roller 8 are closely attached to the rear portion of the circular button 200 but are symmetrically adhered to each other.

Likewise, in FIGS. 10 and 11, when the diameter of the circular button 200 is large, the second step 62 is further moved to set by moving 1/2 of the diameter of the circular button 200 (see FIG. 9).

In addition, the first and second rollers 81 and 81 'of the rear support roller 8 are automatically in close contact with the rear portion of the circular button 200.

At this time, as the diameter of the circular button 200 is increased, the distance between the first and second rollers 81 and 81 'becomes greater, but still supports the positions at mutually symmetrical positions.

In addition, the operating distance of the forward and backward device 63 is adjusted according to the diameter size of the circular button 200, because the width between the guard 24 of the guide means 2 is the diameter of the circular button 200, the guard ( The operating distance of the front and rear propulsion unit 63 is also adjusted as much as the length of the width 24 is adjusted.

That is, when the diameter of the circular button 200 increases, the forward and backward apparatus 63 moves forward, and the distance between the tip end of the first step 61 and the guard 24 increases so that the circular button 200 is placed at the first position P1. Since the front end of the 200 is set to contact the first step 61, as a result, the front end of the circular button 200 touches the first step 61, and both ends of the circular button 200 are guard 24 ), So that three points of support are possible.

This is set by a controller (not shown), and thus a detailed description thereof will be omitted since it is a technical concept that can be sufficiently implemented by those skilled in the art.

12 is a perspective view showing in detail the "back prevention paper member" in the distribution apparatus of the present invention described in FIG.

As shown in FIG. The rear support member 8 is intended to contact and fix the rear end of the circular button 200 supported by the second stepped portion 62 at the same time at the two points at the second correct position P2. The second step 62 and the rear support member 8 support and fix three points forming a triangle of the circular button 200.

The rear support member 8 includes first and second rollers 81 and 81 'which are disposed on the upper portion of the button closure member 6 and are advanced back and forth at equal intervals, and at one end of the first and second rollers. The rollers 81 and 81 'are bearing-coupled and the other ends of the first and

second supports

second supports

83 and 84. And a cylinder device 86 having a link bolt 85 hinged to one end and a rod 862 hinged to the other end of the link bolt 85.

The first and

second supports

83 and 84 are coupled to the guide rail 87 installed in the transverse direction with respect to the second correct position P2, and the link bolt 85 is connected to the lower end thereof. The link bolt 85 is hinged to the block 864 coupled to the rod 862 of the cylinder device 86.

The link bolt 85 is diagonally symmetrically installed at both sides, and when the rod 862 is retracted, the front end of the link bolt 85 is retracted, and the rear end is further opened so that the first and second supports 83 , 84).

On the contrary, when the rod 862 is pulled out, the rear end of the link bolt 85 is closed and the interval between the first and

second supports

83 and 84 is narrowed.

Referring to the operating relationship of the present invention configured as described above are as follows.

When the circular button 200 is put into the hopper H and then operated, the circular button 200 is sequentially discharged through the discharge port 100, and as shown in FIG. 13, each of the circular buttons 200 does not overlap while passing through the shooter B. It is conveyed to the guide means (2).

Subsequently, as shown in FIG. 14, when the circular button 200 is positioned at the rear end of the flat plate 22 of the guide means 2, the circular button 200 is moved forward by the high pressure air injected from the nozzle unit 26. (Dotted arrows indicate the direction of air blowing).

Meanwhile, as shown in FIG. 15, since the first step 61 of the button blocking member 6 is drawn out and positioned in front of the guide means 2, the circular button 200 is moved forward and then the first step. The front end is brought into contact with the stepped portion 61 and is positioned at the first correct position P1.

Then, as shown in Figure 16, the push rod 42 of the button transfer means 4 is lowered to press the upper surface of the circular button 200.

Thereafter, as shown in FIG. 17, the first stepped portion 61 is drawn in, and at the same time, the second stepped portion 62 is drawn out and positioned to intersect the front side of the groove 224 of the flat plate 22.

Thereafter, as shown in FIG. 18, the button transfer means 4 moves forward while the push rod 42 drags the pressed circular button 200 forward, and the front end of the circular button 200 moves to the second step. When it contacts 62, it stops and is put in the 2nd correct position P2.

Subsequently, as shown in FIG. 19, the

rollers

81 and 81 ′ of the rear support member 8 simultaneously move inward to contact and support two points on both sides of the rear end of the circular button 200. One point of the front end is supported by the second stepped 62, and the second point of the second end is supported by the rollers 81 and 81 'so as to be stably supported by three support points corresponding to the vertices of a substantially triangular shape.

At this time, the button feeder E was already rotated in the clockwise direction, and the pin E2 at the tip thereof was in the lower position of the groove 224 of the flat plate 22, that is, in the second correct position. , The button feeder (E) is raised to contact the lower surface of the pin (E2) of the circular button (200).

Then, as shown in Figure 21, in the state that the button feed device (E) continues to be raised, the rotary device 48 installed on the upper portion of the holding rod 42 is driven to rotate the circular button 200 and the button hole and The pin E2 is plugged in at the moment when the pin E2 coincides.

Subsequently, as shown in FIG. 22, the

rollers

81 and 81 ′ of the rear support member 8 are simultaneously opened outwards, the pressing rod 42 is raised to return to its original position, and the second step 62 is Retracted, the button feeder (E) is rotated counterclockwise to transfer the circular button 200 inserted in the pin (E2) to the sewing needle side.

At this time, the first step 61 is withdrawn again at the same time as the second step 62 is pulled out, and another circular button 200 is placed in the first correct position P1.

Therefore, after the forceps installed on the sewing needle side pinch the circular button 200, sewing is performed, and after supplying the circular button 200, the button transfer device E is rotated clockwise again to the second correct position. The pin E2 is placed at P2.
