Description
본 고안은 본원 출원인이 선출한 특허출원 제2005-0007541호에서 용접용 너트(이하 "용접너트"라 함)의 정 방향 공급구조를 개량한 것으로서, 이를 좀더 구체적으로 설명하자면 소재공급통의 용접너트 이송로에 용접너트의 용접돌기를 확고하게 파지시킬 수 있도록 하여 용접너트의 정 방향 공급을 보다 안정적이면서 정확하게 할 수 있도록 하고, 또 일측면에 와셔를 가진 너트(이하 "와셔너트"라 함)도 정 방향 공급할 수 있는 구조를 제공할 있도록 한 것이다.The present invention is an improvement of the forward supply structure of the welding nut (hereinafter referred to as "welding nut") in the patent application No. 2005-0007541 elected by the applicant of the present application, more specifically, the welding nut of the material supply container It is possible to securely hold the welding projection of the welding nut in the conveying path so that the forward feeding of the welding nut can be more stable and accurate. Also, a nut having a washer on one side (hereinafter referred to as a washer nut) is also provided. It is to provide a structure that can be supplied in the forward direction.
본원 출원인이 선 출원한 특허출원 제2005-0007541호의 용접너트의 정 방향 공급구조(이하 "종래구조"라 함)는 소재공급통의 이송로에 안내레일를 돌출 형성하여 그 안내레일 상에 너트가 안착되도록 하면서 양측의 용접돌기가 안내레일 측면에 걸리도록 함으로써 용접너트를 스폿용접기에 정 방향(용접돌기가 하측에 위치되는 상태) 공급되도록 한 것이다.The forward feed structure (hereinafter referred to as "conventional structure") of the welding nut of the patent application No. 2005-0007541 filed by the applicant of the present application protrudes the guide rail in the feed path of the material supply cylinder, and the nut is seated on the guide rail. By making the welding projections on both sides of the guide rail side, the welding nut is supplied to the spot welder in the forward direction (with the welding projection located on the lower side).
이러한 종래구조는 첨부도면 도6에서와 같이 용접너트의 일측 용접돌기 만이 안내레일 측면에 걸려지기 때문에 그 걸림력이 약하여 즉,안내레일 측면과 용접돌기 간의 걸림력 전체(일측의 전후 용접돌기가 한꺼번에 걸려진 상태)가 진동정렬기 의해 진동하는 소재공급통의 진동으로 인하여 쉽게 해제(용접돌기의 이탈)될 수 있게 되어 이송 도중 안내레일에서 용접너트가 이탈하는 경우가 빈번하게 발생 되었고, 이는 용접너트의 안정적인 공급을 저해하였을 뿐만 아니라 정 방향으로 정렬된 용접너트가 배출구로 배출되기 전에 손실되게 하는 문제점을 낳았으며, 또 그 진동은 용접돌기와 안내레일 간의 걸림력 일부를 해제한 경우(일측의 전후 용접돌기 중 전방 또는 후방의 용접돌기 만이 걸려진 상태)도 발생시킬 수 있고, 상기에서 안내레일과 용접돌기 간의 걸림력 일부가 해제된다는 것은 곧 용접너트가 안내레일 상에서 완전히 이탈되지 않은 상태 그대로(정 방향에서 비뚤어진 방향) 배출되는 것을 말하는 것인데, 이와 같은 용접너트의 왜곡방향 공급은 실제로 종래구조에서 종종 발생 되고, 그로 인하여 용접너트의 연속적인 정 방향 공급에 상당한 차질이 초래되는 문제점도 있었다.In the conventional structure, as shown in FIG. 6, only one side of the welding protrusion of the welding nut is caught on the side of the guide rail, so that the grip force is weak, that is, the entire grip force between the side of the guide rail and the welding protrusion (the front and rear welding protrusions at the same time). The jammed state can be easily released (deviation of the welding protrusion) due to the vibration of the material supply cylinder vibrated by the vibration sorter, so that the welding nut is frequently released from the guide rail during transportation. Not only hindered the stable supply of oil, but also caused a problem that the weld nut aligned in the forward direction was lost before being discharged to the outlet, and the vibration was released when part of the clamping force between the welding protrusion and the guide rail was released Only the front or rear weld projections are caught), and the guide rail and the welding The release of a part of the holding force of the period means that the welding nut is discharged as it is not completely separated from the guide rail (a direction that is crooked from the forward direction). Such a distorted direction supply of the welding nut actually occurs in conventional structures. As a result, there is a problem that a significant disruption is caused in the continuous forward supply of the weld nut.
또한 종래구조는 안내레일의 돌출로 인하여 와셔너트를 정 방향으로 공급할 수 없었다. 이를 다시 설명하면 와셔너트는 주지한 바와 같이 너트 일측면에 원형판 형태의 와셔가 부착되어 있어 뒤집어 지더라도 와셔가 용접너트의 용접돌기와 같이 안내레일 측면에 걸려질 수 없는 것이어서 이를 종래구조에 적용하면 와셔너트가 정 방향(와셔가 하측에 위치된 상태) 혹은 뒤집혀짐에 관계없이 항상 안내레일 상에 안착 된 상태가 되므로 이송 도중 무조건 걸림바에 걸려 소재공급통으로 낙하하게 되어 종래구조는 용접너트와 와셔너트(전체 높이가 용접너트에서 용접돌기의 높이를 제외한 높이를 벗어날 수 없는 너트) 겸용으로 사용할 수 없었다.In addition, the conventional structure could not supply the washer nut in the forward direction due to the protrusion of the guide rail. In other words, the washer nut has a circular plate-type washer attached to one side of the nut, and even if it is turned over, the washer cannot be caught on the side of the guide rail like the welding protrusion of the weld nut. Regardless of whether the nut is in the forward direction (with the washer at the bottom) or upside down, the nut is always seated on the guide rail. The overall height could not be used as a nut that cannot escape the height of the weld nut except the height of the weld projection.
본 고안은 상기와 같이 종래구조에서 나타나는 문제점들을 한꺼번에 해결하기 위함에 그 기술적인 과제를 안출한 고안으로서, 특히 용접너트의 용접돌기 전부또는 일부가 소재공급통의 진동에도 불구하고 이탈될 수 없음과 동시에 와셔너트에도 적용가능한 구조를 얻을 수 있도록 한 것이다.The present invention devised the technical problem to solve the problems appearing in the conventional structure at once, in particular, all or part of the welding projection of the welding nut can not be separated despite the vibration of the material supply cylinder and At the same time, it is possible to obtain a structure applicable to the washer nut.
진동정렬기 상부에 장치되면서 나선형 이송로(11)를 가진 소재공급통(1)의 최 상부 정렬이송로(12) 외주벽 일정위치에 곡률형 걸림바(3)를 비스듬히 설치하고, 상기 정렬이송로(12) 상면은 소재공급통(1) 중심부 방향으로 경사지게 형성하되, 그 끝부에 배출구(13)를 연장 형성하는 것에 있어서, 소재공급통(1)의 정렬이송로(12) 상면 양측에 용접너트(4) 양단의 용접돌기(41)가 각기 수용될 수 있는 이송안내홈(2)(2')을 형성하고, 걸림바(3) 내측 하단에는 용접너트(4)가 정 방향일 때 그 내측 상단이 접촉되지 않은 크기의 걸림돌기(31)를 형성하여서 된 것이며, 상기에서 이송안내홈(2)(2')은 가공의 편리성 및 원가 등에 따라 정렬이송로(12)에 관통될 수도 있다. The curvature-type locking bar 3 is installed at an angle on the outer circumferential wall of the uppermost alignment transfer path 12 of the material supply container 1 having the spiral transfer path 11 while being installed on the vibration sorter, and the alignment transfer is performed at an angle. The upper surface of the furnace 12 is formed to be inclined in the direction of the center of the material supply cylinder 1, and the discharge port 13 extends at the end thereof, and is welded to both sides of the upper surface of the alignment feed path 12 of the material supply cylinder 1. The welding projections 41 at both ends of the nut 4 form a feed guide groove 2 and 2 ′ which can be accommodated, respectively, and when the welding nut 4 is in the forward direction at the inner lower end of the catching bar 3. It is to form a locking projection 31 of the inner top is not in contact with the size, wherein the transfer guide groove (2) (2 ') may be penetrated through the alignment transfer path 12 in accordance with the convenience and cost of processing. have.
이와 같이 구성 본 고안은 소재공급통(1)의 정렬이송로(12) 상면 양측에 형성되는 이송안내홈(2)(2')에 용접너트(4) 양단의 용접돌기(41)를 각기 끼워질 수 있으므로 진동 이송 도중 용접돌기(41)의 이탈을 막을 수 있음은 물론 혹시 일단 전후의 용접돌기가 이송안내홈(2)(2')에서 이탈되더라도 종래구조와 같이 용접너트(4)의 방향이 바뀌는 것이 방지되며,As such, the present invention fits the welding protrusions 41 at both ends of the welding nut 4 to the transfer guide grooves 2 and 2 'formed at both sides of the upper surface of the alignment transfer path 12 of the material supply container 1, respectively. As a result, the welding protrusion 41 may be prevented from being removed during the vibration transfer, and even if the welding protrusions before and after the first and second welding protrusions are separated from the transfer guide grooves 2 and 2 ', the direction of the welding nut 4 may be reduced. Is prevented from changing
또 상기의 이송안내홈(2)(2')은 정렬이송로(12) 상면을 평평하게 하여 와셔너트(5)의 정 방향 공급도 가능케 한다. 즉 첨부도면 도5의 (가)에서와 같이 와셔너트(5)가 정 방향일 때(와셔부분이 하측에 위치할 때)에는 와셔너트(5)는 정렬이송로(12)를 이송 안내면으로 하여 아무런 장애 없이 걸림바(3) 밑을 통과하면서 배출구(13) 쪽으로 정 방향 이송되나, 와셔너트(5)가 역 방향일때(와셔부분이 상측에 위치할 때)에는 첨부도면 도5의 (나)에서와 같이 와셔부분(51)이 걸림바(3) 내측 하단의 걸림돌기(31)에 걸리게 되어 이송되지 못하고 소재공급통(1)으로 낙하하게 된다.In addition, the transfer guide groove (2) (2 ') is to make the upper surface of the alignment transfer path (12) to enable the forward feed of the washer nut (5). That is, when the washer nut 5 is in the forward direction (when the washer part is located at the lower side) as shown in (a) of FIG. 5, the washer nut 5 is used as the transfer guide surface. It is conveyed forward toward the outlet 13 while passing under the catching bar 3 without any obstacle, but when the washer nut 5 is in the reverse direction (when the washer part is located on the upper side), As in the washer portion 51 is caught by the engaging projection 31 of the inner bottom of the locking bar (3) can not be transported to fall to the material supply container (1).
따라서 본 고안은 상기한 바와 같이 용접너트(4)가 정 방향 이송될 때 소재공급통(1)의 진동 등에 의한 이탈 및 방향 변경을 방지할 수 있으므로 용접너트(4)를 보다 안정적이면서 정확하게 정 방향 공급할 수 있는 이점이 있고, 나아가 연속적인 정 방향 공급의 효과도 발휘할 수 있으며, 또 용접너트와 와셔너트 모두를 정 방향 공급할 수 있는(겸용으로 사용할 수 있는) 구조를 얻을 수 있게 된다.Therefore, the present invention can prevent the separation and the change of direction due to the vibration of the material supply container 1 when the welding nut 4 is conveyed in the forward direction as described above. There is an advantage that can be supplied, and furthermore, the effect of continuous forward feeding can be exhibited, and a structure capable of forward feeding (used in combination) both of the weld nut and the washer nut can be obtained.
