Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a button transfer device capable of transferring buttons to a sewing machine sewing section.

Conventionally, there has been known a vibrating button feeder that selects the front and back sides and thickness of buttons and transports them from a shooter to a sewing section of a sewing machine.

However, if the button is made of natural materials such as shells, the maximum thickness of the button can be controlled by polishing, but due to variations in the material itself, the overall thickness of one button cannot be kept constant. As shown in FIG. 1, a button 1 with a wedge-shaped cross section is formed, with one side having a maximum thickness H and the other side having a minimum thickness h (H>h). There is.

As shown in FIGS. 2 and 3, the discharge port 3 of the shooter 2 is formed at a height L that is slightly larger than the maximum thickness H of the button 1. When the height h is less than half of the height L of the discharge port 3, when two sheets are sent to the discharge port 3 in piles, these buttons 1 are pressed against the discharge port 3 as shown in the figure.
There was a drawback that the button 1 could not be fed to the sewing machine sewing part because of the pinching.

This invention was devised by focusing on these drawbacks, and its purpose was to place buttons that would get stuck in the outlet, i.e., buttons whose minimum thickness was less than half of the outlet, into the transfer path in advance. An object of the present invention is to provide a button transfer device that can be eliminated more easily.

An embodiment of this invention will be described below with reference to FIGS. 4 to 7.

In FIG. 4, reference numeral 4 denotes a bowl-shaped bowl of a button transfer device that vibrates in conjunction with a known vibration device (not shown).

Reference numeral 5 denotes a transfer path formed inside the bowl body 4 in the form of an inverted cone, and a discharge port 6 of a chute 6 disposed at the top.
It extends to A.

The discharge port 6A of the chute 6 is formed with a height L slightly thicker than the maximum thickness H of the button 1 so that the buttons 1 do not overlap within the chute 6 and the button 1 slides smoothly inside the chute 6. It is formed with a height that allows only one button of thickness H to pass through.

7 is a transfer path 5 and a side wall 5A standing upright on its outer periphery.
As shown in FIG. 5, a part of the side wall 5A of the transfer path 5 is cut out, and the road surface 5a of the transfer path 5 and the restriction plate 7 are cut out in this part. It is supported by screws 8 or the like so that the height of the discharge port 6A from the lower end surface 7a is approximately half the height L of the discharge port 6A.

The regulation plate 7 is arranged in front of the chute 6 of the transfer path 5, and the height from the upper surface of the transfer path 5 below the regulation plate 7 serving as the side wall 5A is set to the height L of the discharge port 6A. A side hole X is formed which opens to the side and has a height C that is half of the height C. Y is transfer path 5
The pilot hole is opened at the outer circumferential side of the transfer path 5 and communicates with the side hole There is.

The upper surface of the side hole X (lower end surface 7a of the regulating plate 7)
The distance A between the inner surface 5b of the pilot hole Y and the inner surface 5b of the lower hole Y is longer than the maximum thickness H of the button 1 and shorter than twice the maximum thickness H of the button 1.

The side hole X and the lower hole Y form a sorting port Z that excludes buttons 1 having a thickness smaller than half the height of the discharge port 6A from the transfer path 5 to the outside of the bowl body 4. .

In addition, in FIG. 5, the regulating plate 7 may be formed integrally with the side wall 5A.

Next, the operation of this invention will be explained.

First, when the button 1 is inserted into the bowl 4 and the vibration device (not shown) is started, a spiral torsional vibration is applied to the bowl 4, and the button 1 is moved upward along the transfer path 5. and reaches the regulation plate 7.

Now, as shown in FIG. 6, the maximum thickness is H, and the minimum thickness h is the height C between the transfer path 5 and the regulating plate 7 (C≒
Suppose that the button 1 having a smaller shape than L/2), that is, the button 1 that is likely to get clogged in the outlet 6A of the chute 6, approaches the regulation plate 7. Then, such a button 1 can enter the side hole X in the lower surface of the regulating plate 7 from the portion of the minimum thickness h. If the button 1 enters further and extends beyond the outer circumferential edge 5b of the transfer path 5 by more than the radius of the button 1, the balance of the button 1 will be lost, and the button 1 will be inserted into the side hole X between the regulating plate 7 and the road surface 5a of the transfer path 5. and is removed to the outside of the transfer path 5 through a sorting port Z formed by a pilot hole Y. At this time, since the distance A between the inner lower edge 7b of the regulating plate 7 and the outer circumferential edge 5b of the transfer path 5 is larger than the maximum thickness H of the button 1, the button 1 may be caught between the regulating plate 7 and the road surface 5a. It is reliably removed to the outside of the transfer path 5.

Next, as shown in FIG. 7, the button has a shape in which the maximum thickness is H and the minimum thickness h is larger than the height C between the transfer path 5 and the regulating plate 7, that is, the outlet 6A of the chute 6. Suppose that the button 1, which is not easily clogged, approaches the regulation plate 7. Then, since the minimum thickness h of such a button 1 is larger than the height C between the regulating plate 7 and the road surface 5a, the button 1 cannot enter the side hole X on the lower surface of the regulating plate 7 at all. For this reason, like the button 1 described above, the material outside the transfer path 5 is guided to the discharge port 6A and sent from there to the sewing machine sewing section. The minimum thickness h of such a button 1 is more than half the height L of the outlet 6A, so even if two sheets are stacked and sent to the outlet 6A, the height of the heavy button will be more than L, so the button 1 will not be able to reach the outlet 6A. There is no risk of getting stuck.

As mentioned above, according to this invention, it is possible to eliminate buttons whose minimum thickness is less than half the height of the ejection port. Clogging can be reliably prevented and the button can be smoothly fed to the sewing machine sewing part.
