Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button delivery device for supplying buttons with a large chamfer on top to a button sewing machine or the like.

Conventionally, in order to sort out the front and back sides of buttons and supply buttons with the front side up, we have used a chute that has a spiral rail and a continuous opening on the upper terminal plane of the rail, and a chute that has a spiral rail and a continuous opening in the plane at the upper end of the rail. The button is equipped with a sorting means for dropping the reversed button downward from the tooth provided on the upper surface of the rail by utilizing the fact that the concave part on the surface of the button faces the sawtooth tip and the button is tilted toward the center of the bowl. A feed-out bowl has been proposed, but in this type of bowl, as shown in Figure 6, if the button has no recesses on either the front or back, it will pass through without tilting even if it rests on the serrated teeth on either side. Therefore, buttons other than buttons with a recess in the center of one side could not be sorted, but this invention utilizes the difference in the size of the upper and lower chamfers on the outer circumference of the button to separate the front and back of buttons that do not have a recess on the surface. The purpose is to make it possible to select.

Below, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a bowl capable of accommodating a large number of buttons A at its bottom, and is subjected to vibration by an appropriate vibration source.

Reference numeral 2 denotes a conical spiral rail formed on the bowl 1, and the button inside the center moves along the rail 2 due to the vibration of the bowl 1.
ascends sequentially along the

3 is a flexible chute, one end of which is connected to the rail 2.
It has an opening (not shown) continuous with the exit plane of the button, and the other end is connected to a transfer mechanism (not shown) for transferring the button to the button sewing machine.

Reference numeral 4 denotes a guide plate for guiding the button A to the opening of the chute 3, and its base is fixed to the inner surface of the outer wall 5 of the bowl 1 with screws 6 through elongated holes in the circumferential direction.

Reference numeral 7 denotes a first regulating plate for preventing the buttons from stacking up at the opening of the chute 1, and its base is fixed to the outer wall of the bowl 1 with screws 8 through elongated holes in the vertical direction.

Reference numeral 9 denotes a first sorting plate, which has one end that is flush with the upper surface of the rail of the bowl 1 and a serrated sorting part 9a, and the other end that extends outward from the notch 10 in the outer wall 5 of the bowl 1. The bowl 1 is fixed to a support portion 11 provided in the bowl 1 by screws 13 through long holes 12 in the radial direction of the bowl 1.

Reference numeral 14 denotes an auxiliary outer wall whose both ends are fixed to the outer periphery of the outer wall 5 of the bowl 1 with screws 15, and whose center portion is fixed to the outer periphery of the outer wall 5 of the bowl 1.
It has an arcuate shape so as to form an outer wall of the notch 10 portion, coinciding with the inner circumferential surface of the notch.

A second sorting plate 16 is vertically supported on the inner circumferential surface of the auxiliary outer wall 14, and has a slope 16a facing the first sorting body 9 and tilting downward at the lower end, and a slope 16a facing the first sorting body 9 in the vertical direction at the upper end. A pair of elongated holes are provided in and fixed to the auxiliary outer wall 14 with screws 17 so as to be movable and lockable up and down.

A second regulating plate 18 prevents the button A from stacking on the rail, and its base is fixed to the inner circumferential surface of the outer wall 5 of the bowl 1 with a screw 19 through an elongated hole in the vertical direction.
In order to supply one button A to the sorting part 9a of the first sorting body 9, a gap slightly wider than the thickness of one button A is formed between it and the upper surface of the rail 2.

Further, reference numeral 20 denotes an inclined surface provided on the bowl 1 below the sorting section 9a and allowing the flip button to fall downward.

This invention has the above structure, and when a large number of buttons are placed inside the bowl 1 and the bowl 1 is vibrated, the buttons A ride on the spiral rail 2 and gradually spiral outward. It rises.

Therefore, when the buttons A stacked high in the center of the bowl 1 reach the second regulating plate 18, the buttons A above the bottom surface hit the second regulating plate 18 and fall onto the lower rail 2. Only the button A at the bottom passes directly under the second regulating plate 18 and is delivered onto the first sorting plate 9.

As shown in the figure, button A has different sizes of chamfers on the upper and lower edges of the outer circumference of the button. The tip of the slope 16a of the sorting plate 16 pushes it toward the center of the bowl 1, and the center of gravity moves outside the sorting part 9a of the first sorting plate 9, so that the vibration of the bowl 1 causes the center of gravity to move outside the sorting part 9a of the first sorting plate 9. However, if the large chamfered part is facing upward as shown by the solid line in FIG. Since it enters deeply into the gap between the first sorting plate 9 and the first sorting plate 9, the center of gravity does not come off the first sorting plate 9, and it passes over the upper surface of the first sorting plate 9 as it is and is delivered to the opening of the chute 3.

If the thickness of the button or the size of the upper chamfer changes, the second sorting plate 16 may be moved up and down accordingly and fixed to the auxiliary outer wall 14 with screws 17 at a desired position.

Also, if there is a large chamfer on the back of the button, only the button with the back facing up will be sent to the opening of chute 3, but if chute 3 is twisted 180 degrees and installed, the button that has passed through chute 3 will be exposed. becomes upward.

As described above, in this invention, when the button is placed on the rail, the button is placed on the rail so that the large chamfer formed on the upper and lower surfaces of the outer periphery of the button is on the top. A sorter is provided with an edge that pushes the buttons toward the center of the bowl so that they fall off the track when placed on the machine, so it is possible to sort the front and back of buttons that have no recesses on either the upper or lower surfaces, and can be combined with a button sewing machine. This increases the number of types of buttons that can be mechanically fed, increasing the added value of the button sewing machine.In particular, buttons with large chamfers on the outside can be sent out as they are, which improves the efficiency of button sewing. It has an improving effect.

In the above-mentioned embodiment of the present invention, the slope of the second sorting plate is formed so as to face the whole length of the sorting part of the first sorting plate, The same effect as described above can also be obtained by providing one or more second sorting plates having opposing slopes.

Further, in the embodiment of the present invention, the single second sorting plate is movable and lockable in the vertical direction of the bowl, but the third sorting plate
As shown in the figure, a plurality of (two in the embodiment) sorting plates 21
．． The same effect as described above can be obtained even if each of the second sorting plates 22 is movably and lockably supported by screws 17 on the auxiliary outer wall 14, or if one end surface corresponding to the slope of the second sorting plate is formed horizontally.

Further, in the embodiment of the present invention, the second sorting plate 16 is supported by the bowl auxiliary outer wall 14 so as to be movable and lockable in the vertical direction by screws 17, but as shown in FIG. The sorting plate 16 is placed on the upper surface of the first sorting plate 9 and is supported so as to be movable and lockable in the left and right directions with respect to the bowl 1 through the long holes in the left and right direction with screws 13, and the slope 16a of the sorting plate 16 is tilted downward. The same effect can be obtained even if it is tilted to .

In this case, as another embodiment, as shown in FIG. 5, even if a plurality of sorting plates 23 and 24 are movably supported on the bowl 1 by screws 13, the end surface corresponding to the slope 16a may be vertically disposed. It may be of any shape.
