Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel component feeder. More specifically, it is an object of the present invention to provide a novel component supply device capable of automatically and continuously supplying a disc-shaped component having a hole at its center to a receiving portion.

[0002]

2. Description of the Related Art A disc-shaped part having a hole in its center,
For example, when binding one element of a disc-shaped surface fastener to a sheet-shaped member with an eyelet, the eyelet is supported on the upper surface of the receiving portion that is the die, and the tubular portion of the eyelet is seated. The surface fastener element is bonded to the sheet-shaped member by inserting it into the hole of the strip-shaped member and the hole of the surface fastener element and crimping the tubular portion of the eyelet protruding from the hole of the surface fastener element.

[0003]

However, in the prior art, there is no device for automatically and continuously supplying the surface fastener element to the receiving portion which is a die, and therefore, the surface fastener element is supplied to the receiving portion by hand each time. And was very inefficient.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a component supply device of the present invention comprises a stock portion for placing a large number of components in a stack and a guide groove having an outer diameter substantially equal to that of the component. And a protrusion having a protrusion plate that protrudes the part located at the lowermost end of the stock portion on the opposite side of the stock portion with the stock portion interposed between the stock portion and the guide groove of the feed portion. The feeding section is composed of a base portion near the stock portion and a movable portion rotatably connected to the base portion, and at least one width of the movable portion is outside the part outside the guide groove in the guide groove of the movable portion. A mechanism for forming an insertion hole smaller than the diameter and for moving the movable part up and down is provided, and when the movable part rotates downward, the upper end of the receiving part is inserted from below into the insertion hole at the tip of the movable part. The parts located at the tip of the movable part are It is obtained so as to be received.

[0005]

Therefore, in the component feeding apparatus of the present invention, the components are sequentially fed to the feeding portion by the ejecting plate, and are positioned at the tip of the feeding portion each time the movable portion is rotated downward.

Then, the fixture 44 is fixed to an appropriate machine frame, the adjusting screw shaft 42 of the mounting base 41 is screwed into the nut member 45, and the screw inserted from below into the long hole 43 at the tip of the mounting base 41. 46 is screwed into the screw hole 40 of the stay 38,
As a result, the stay 38 is supported by a suitable machine frame or the like via the mounting base 41 and the fixture 44. Then, the height is adjusted by adjusting the screwing amount of the adjusting screw shaft 42 into the nut member 45, and the position in the longitudinal direction of the mounting base 41 is changed by changing the position of the long hole 43 into which the screw 46 is inserted. Each is adjusted.

The surface fastener elements 2, 2, ...
Are overlapped and the rod portion 17 of the holding rod 14 is inserted into the holes 5, 5, .... And the rod part 1 in which many surface fastener elements 2, 2, ...
The lower end of 7 is inserted into the supply hole 11 of the supply block 10 from above, and then the screw shaft 16 at the upper end of the rod 17 is inserted into the insertion hole 18 of the support plate 12 and screwed into the screw hole 15a of the head 15. To do. As a result, the hook-and-loop fastener elements 2, 2, ...
.. are stocked in the supply hole 11 and above it. still,
The surface fastener elements 2, 2, ... Are their bases 3, 3,
It is stocked in the direction with .. Then, the surface fastener element 2 located at the lowest end is located in the guide groove 9.

Then, when the motor 20 of the protruding portion 25 is driven, the stock portion 19 is moved by the protruding plate 22.
When the hook-and-loop fastener element 2 located at the lowermost end of the push-out plate goes out and the push-out plate 20 moves backward, the second hook-and-loop fastener element 2 from the bottom moves to the lowest end, and when the push-out plate 20 moves forward next The hook-and-loop fastener element 2 moved to the lowermost end is projected. In this manner, the surface fastener elements 2, 2, ... Which are stacked by the reciprocating movement of the ejection plate 20 are fed one by one.
Is sent to.

The hole 5 of the surface fastener element 2 positioned at the tip of the tilting plate 26 corresponds to the insertion hole 29,
Elastic plates 30 are provided on the upper side of the portions located on both sides of the guide groove 9.
The edge portions 30a, 30a of 30 are positioned.

Reference numeral 47 is a receiving portion which serves as a crimping die,
It is located below the tip of the tilt plate 26, and its upper end is positioned so as to pass through the insertion hole 29 of the tip of the tilt plate 26 from below when the tilt plate rotates downward.

A receiving pin 48 is provided so as to project from the upper end surface of the receiving base 47, an upper half portion 48a of the receiving pin 48 is formed to have a smaller diameter than the lower half portion 48b, and the upper half portion 48 is formed.
The a is slidable in the vertical direction with respect to the lower half portion 48b, and is urged to move upward by elastic means (not shown).

Then, when the tilting plate 26 rotates downward, the receiving pin 48 is relatively inserted through the insertion hole 29 of the tilting plate 26 from below, and at this time, the small diameter portion 48a of the receiving pin 48 tilts. It is inserted into the hole 5 of the hook-and-loop fastener element 2 located at the extreme end of the plate 26.

When the receiving pin 48 is inserted up to the upper end surface of the large diameter portion 48b, the receiving portion 47 moves relatively upward as the tilting plate 26 moves downward. The element 2 receives the force of moving upward together with the receiving portion 47. And the surface fastener element 2
Since it is the edge portions 30a, 30a of the elastic plates 30, 30 that prevent the upward movement of the elastic plates 30, 30, the edge portions 30a, 30a of the elastic plates 30, 30 move upward due to the upward movement force. The surface fastener is turned up, whereby the surface fastener element 2 moves upward together with the receiving portion 47 (see FIG. 5).

In this way, the surface fastener element 2 is supplied onto the receiving portion 47.

Then, the cardboard 1 is supplied and the receiving pins 4 are supplied.
A portion of the small diameter portion 48 a of the reference numeral 8 protruding upward from the hole 5 of the surface fastener element 2 is inserted into the mounting hole 6 of the cardboard 1.

Then, a punch (not shown) descends with the eyelet 7 held with the tubular portion 7a thereof facing downward. Then, the tubular portion 7a of the eyelet 7 is inserted through the mounting hole 6 of the cardboard 1 and the hole 5 of the surface fastener element 2 in this order, and passes through the hole 5 of the surface fastener element 2 of the tubular portion 7b downward. The portion is crimped and the hook-and-loop fastener element 2 is bound to the cardboard 1. At the time of punching, the small diameter portion 48a of the receiving pin 48 retracts into the receiving portion 47 against the elastic force of the elastic means (not shown) so as not to interfere with the punching.

In this way, the hook-and-loop fastener element 2 located at the leading edge of the feeding section 31 is bound to the cardboard 1.
Then, the motor 34 rotates and the cam 36 causes the tilting plate 2 to move.
6 is rotated upwards until it is in a substantially horizontal posture, and the motor 20 is rotated to reciprocate the projecting plate 22, and a new surface fastener element 2 from the stock portion 19 to the feeding portion 31.
The hook-and-loop fastener element 2 which has been positioned second from the most distal end is pushed onto the insertion hole 29. By repeating such an operation, the surface fastener elements 2 are sequentially bound to the cardboard 1.
