Field of the Invention The present invention relates to nut feeders, and more particularly, to a head assembly for a nut feeder configured with a head jig for transferring a directional nut to a destination in an accurate direction.

일반적으로, 자동차, 선박, 비행기 등 각종 패널(panel)에 의장부품을 장착하기 위하여는 먼저 상기 패널에 티너트(T nut), 용접너트(projection nut) 등 여러 너트들 중 적합한 너트를 선택하여서 부착하여야 한다.In general, in order to mount design parts on various panels, such as automobiles, ships, airplanes, first, a suitable nut is selected from various nuts such as a T nut and a projection nut. shall.

좀 더 상세히는, 너트정렬기와 헤드어셈블리로 구성된 너트피더(nut feeder)를 통하여 너트용접기의 피용접물(패널)로 너트를 자동 공급 및 이송한 후 상기 너트와 피용접물을 너트용접기로서 접합한다. 그리고, 적소에 너트가 부착된 패널을 자동화 생산라인으로 공급되게 하여 다음 단계에서 볼트 등으로써 각종 부품들을 용이하게 장착하는 것이다.In more detail, the nut and the welded object are joined as a nut welder after automatically feeding and conveying the nut to the welded object (panel) of the nut welder through a nut feeder composed of a nut aligner and a head assembly. Then, the panel with the nut in place is supplied to the automated production line to easily mount various parts such as bolts in the next step.

하지만 이때, 티너트나 용접너트와 같이 방향성이 있는 너트는 상하가 뒤집히거나 좌우가 회전되거나 또 일측으로 편심된 채 피용접물에 놓여지면 상기 너트와 피용접물이 제대로 접합되지 않게 된다. 그리고, 제대로 접합되지 않는 방향성의 너트에 부품이 장착되면 내구성이 저하되게 된다. 따라서, 이러한 방향성 너트의 접합불량률을 검출하지 못하고 그대로 제품화되어 나갈 경우 소비자들의 안전에 심각한 악영향을 미칠 수도 있는 것이다.However, in this case, the nut having a directionality such as a tin nut or a weld nut is placed upside down, left and right rotated or eccentrically to one side to be welded and the nut and the welded body are not properly joined. And when a component is attached to the directional nut which is not joined correctly, durability will fall. Therefore, if the product is not produced without detecting the defective defect rate of the directional nut, it may seriously affect the safety of consumers.

본 발명의 목적은, 방향성이 있는 너트를 목적지에 항상 정방향 공급할 수 있도록 한 헤드지그가 구성된 너트피더용 헤드어셈블리를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a head assembly for a nut feeder in which a head jig is configured so that a directional nut can always be forwarded to a destination in a forward direction.

지금부터, 본 발명의 실시 예들로서 헤드지그(40)가 방향성이 있는 너트(N)들을 정방향으로 꽉 집은 상태로 목적지까지 이송하는 과정을 설명한다.Now, as an embodiment of the present invention will be described the process of the head jig 40 is transferred to the destination in the state in which the directional nuts (N) tightly packed in the forward direction.

먼저, 너트정렬기(4)로 용접너트(N1) 또는 티너트(N2)를 투입하여서 엉킴이 풀리고 상하 및 좌우가 정방향으로 자동정렬된 후 일정 시간 간격으로 하나하나씩 피딩호스(4a)를 통해 너트피더용 헤드어셈블리(6)의 헤드부(50)로 공급되게 한다(도 7).First, the welding nut (N1) or the nut (N2) is put into the nut aligner 4, the entanglement is released, and the top, bottom, left and right are automatically aligned in the forward direction, and then the nut is fed one by one at a predetermined time interval. It is supplied to the head part 50 of the feeder head assembly 6 (FIG. 7).

헤드부(50)의 입구로 공급된 용접너트(N1) 또는 티너트(N2)는, 도 3a 및 도 3b에서와 같이, 중력에 의해 너트공급안내로(52)를 하강하여서 캐치홀(54)에 대기 위치하는 헤드지그(40)의 그립홈(44)에 도달하여서 최종 이송 대기 상태에 놓여지게 된다. The welding nut N1 or the tin nut N2 supplied to the inlet of the head part 50 descends the nut supply guide 52 by gravity as shown in FIGS. 3A and 3B to catch the hole 54. The grip groove 44 of the head jig 40, which is in the standby position, is reached and placed in the final transfer standby state.

이때, 공급 시 상하 방향이 주요한 용접너트(N1)는, 도 3a에서처럼 저부 용접 부분이 개폐문(56)을 향하게 된다. 또, 상하 및 좌우방향이 모두 주요한 티너트(N2)는, 도 3b에서처럼 저부 머리 부분이 개폐문(56)을 향하면서 머리 부분의 호형 양 측부는 상하를 향하고 선형 양측부는 헤드지그(40)를 향하게 되는 바, 이러한 공급이 가능하도록 너트공급안내로(52)를 형성한다. 또, 캐치홀(54) 바닥면에는 자석(도면에 미도시)을 구성함으로써 자성(magnetism)에 의하여 너트(N)들이 더욱 신속하게 하강하도록 구성할 수도 있다.At this time, the welding nut (N1) in the vertical direction at the time of supply, the bottom welded portion is directed toward the opening and closing door 56, as shown in Figure 3a. In addition, the upper and lower and left and right directions of the main nut (N2), as shown in Fig. 3b, the head of the head toward the opening and closing door 56, the arc-shaped both sides of the head portion up and down and the linear both sides toward the head jig 40 The nut supply guide 52 is formed to enable such a supply. In addition, by forming a magnet (not shown) on the bottom surface of the catch hole 54, the nuts N may be lowered more quickly by magnetism.

다음으로, 도 6에 도시한 바와 같이, 헤드부(50)의 캐치홀(54) 내 헤드지그(40)의 그립홈(44)에 여유있게 안착된 용접너트(N1)는, 본체작동부(20)에 의하여서 일단 헤드지그(40)의 양쪽 집게바(42a)(42b)에 꽉 집힌 채 헤드부(50)의 개폐문(56)을 통과하여 목적지까지 이송 후 정방향으로 놓아두고 헤드지그(40)만 본체작동부(20)로 복귀하는 것이다.Next, as shown in FIG. 6, the welding nut N1 that is comfortably seated in the grip groove 44 of the head jig 40 in the catch hole 54 of the head part 50 is the main body operation part ( 20, once tightly clamped to both tongs 42a and 42b of the head jig 40, passing through the opening and closing door 56 of the head 50 to the destination and left in the forward direction, the head jig 40 ) Is only to return to the main body operating unit (20).

더욱 상세히는, 도 6의 (b)와 같이, 본체작동부(20)의 소형실린더(26)의 작동에 의해 벌림편(28)이 베어링(34)들 사이로 전진하여 헤드지그(40) 집게바(42a)(42b)의 후단을 벌려주면 탄성 지지부(36)가 이완되어 집게바(42a)(42b)의 선단이 죄어들면서 그립홈(44) 내의 용접너트(N1)를 꽉 집는다. 연속하여, 상기 상태에서 도 6의 (c)와 같이, 실리더(10)의 작동으로 피스톤로드(12)가 전진함으로써 상기 헤드블럭(40)이 LM가이드(30)의 LM블럭(32)과 함께 전진하여 목적지로 용접너트(N1)를 이송한다. 그 다음에 본체작동부(20)의 소형실린더(26)의 작동으로 이완되었던 탄성 지지부(36)가 복원되면서 집게바(42a)(42b)가 초기 평행상태로 회복되고 그립홈(44)이 이완되면서 용접너트(N2)가 목적지에 놓여지게 된다. 그리고, 실린더(10)는 헤드지그(40)가 본체작동부(20)로 복귀하도록 한다.More specifically, as shown in (b) of FIG. 6, the opening piece 28 is advanced between the bearings 34 by the operation of the small cylinder 26 of the main body operation part 20 so that the head jig 40 tongs bar When the rear ends of the 42a and 42b are opened, the elastic support 36 is relaxed, and the tip of the tongs 42a and 42b is tightened to tightly weld the weld nut N1 in the grip groove 44. 6, in the above state, as the piston rod 12 moves forward by the operation of the cylinder 10, the head block 40 and the LM block 32 of the LM guide 30 Advance together and transfer the weld nut (N1) to the destination. Then, as the elastic support part 36, which was relaxed by the operation of the small cylinder 26 of the main body operation part 20, is restored, the tong bars 42a and 42b are restored to the initial parallel state and the grip groove 44 is relaxed. As the welding nut (N2) is placed at the destination. In addition, the cylinder 10 allows the head jig 40 to return to the main body operation part 20.

한편, 헤드부(50)의 개폐문(50)은, 도 5의 (a), (b)에 도시한 바와 같이, 소형실린더(58)의 작동으로 복원 스프링(60)이 압축되면서 개폐문(50)이 열림과 동시에 용접너트(N2)를 꽉 집은 헤드지그(40)가 목적지로 진출한다. 또, 목적지에 용접너트(N2)를 놓고 헤드지그(40)가 본체작동부(20) 내로 복귀하자마자 다시 상기 소 형실린더(58)가 작동하면서 압축되었던 복원 스프링(60)도 이완되면서 순식간에 개폐문(50)이 닫힌다.On the other hand, the opening and closing door 50 of the head 50, as shown in Figs. 5 (a), 5 (b), while the restoration spring 60 is compressed by the operation of the small cylinder 58, the opening and closing door 50 Simultaneously with this opening, the head jig 40 which pinches the welding nut N2 advances to the destination. In addition, as soon as the head nut 40 is returned to the main body operation part 20 with the welding nut N2 at the destination, the restoring spring 60, which has been compressed while the small cylinder 58 is operated, also relaxes and opens and closes in an instant. 50 is closed.

이상이 1회의 정방향 너트(N) 이송 과정이다.That is the one forward nut N feeding process.
