기계식 성형 턴업 드럼{Mechanical Turn-up for Drum} Mechanical Turn-up Drums

본 발명은 타이어의 반제품인 그린케이스를 성형하는 장치에 있어서 그린케이스 기계식 성형 턴업 드럼에 관한 것이다.The present invention relates to a green case mechanical forming turn-up drum in an apparatus for forming a green case which is a semi-finished product of a tire.

종래의 경우 도 1 및 도 2 의 (a)내지 (c)에 도시된 바와 같이 승용차용 공기입 타이어의 제조공정인 성형공정에서 각 반제품을 조립하는 과정 중 바디플라이(Body Ply, 3) 턴업(turn up)작업시 좌, 우측 브레다(Bladder, 4)에 일정한 압력과 시간을 적용시켜 작업하므로 써 그린케이스 형상을 갖출 수 있도록 하여 준다.In the conventional case, as shown in FIGS. 1 and 2 (a) to (c), the body ply (3) turn-up during the process of assembling each semi-finished product in a molding process, which is a manufacturing process of a pneumatic tire for a passenger car. During turn up work, it applies a certain pressure and time to the left and right Bradders (4) so that the green case shape can be provided.

즉 도 2의 (a)내지 (c)에 도시된 바와 같이 좌, 우측 브레다(4)에 적용하는 압력 또는 브레다의 사용 상태에 따라 좌, 우 팽창 불균일성을 초래하여 조립하는 과정 중 품질에 막대한 영향을 끼친다. (도 2의 미설명부호 1은 턴업드럼, 2는 비드 어셈블리이다.)In other words, as shown in (a) to (c) of FIG. 2, the pressure applied to the left and right Breda 4 or the use state of the Breda causes the left and right expansion nonuniformity, which greatly affects the quality during the assembly process. Exerted. (Description 1 in Fig. 2 is a turn-up drum, 2 is a bead assembly.)

상술한 바와 같은 종래의 기술은 반제품 조립과정 중 바디플라이(3) 턴업 작업시 좌, 우측 브레다(4)에 일정한 압력을 넣어 줌으로 써 팽창되도록 하여 부착시켜 주는 기능을 가지고 있으며 좌, 우측 브레다(4)의 팽창 정도에 따라 브레다의 팽창 불균일을 초래하여 품질저하의 요인으로 작용하고 있어 브레다는 일정기간 사용하면 수명이 다하여 교체를 하게 된다. 이 때 교체에 의한 비용증가와 교체시간 발생에 따른 손실(Loss Time)이 생기게 되어 생산성 저하라는 막대한 손실로 이어지는 것이다.The prior art as described above has a function of attaching a predetermined pressure to the left and right breda (4) during expansion of the body fly (3) turn-up during the semi-finished assembly process to expand and attach to the left and right breda ( Depending on the degree of expansion of 4), Breda's expansion is uneven, which causes deterioration of quality. In this case, the cost of replacement and loss time due to replacement time are generated, leading to a huge loss of productivity.

본 발명은 상술한 바와 같이 타이어를 제조하는 과정 중에 성형공정에서 그린케이스를 만들기 위한 반제품 조립시 바디 플라이를 부착한 후 턴업 시키는 방법을 기존의 브레다를 이용하던 것을 기계적인 방법으로 변경적용시킴으로 써, 좌 우 조립 품질 불균일성 발생요인을 완전히 제거하고자 한다.According to the present invention, a method of turning a body ply after attaching a body ply during assembly of a semi-finished product for making a green case during a manufacturing process of a tire as described above is applied by changing a mechanical method using a conventional Breda, We want to completely eliminate the causes of left and right assembly quality non-uniformity.

즉 본 발명은 공기입 자동차 타어의 제조장치에 있어서 각 반제품을 성형하는 공정에서 1차 성형 드럼 턴업 방식을 기존의 브레다를 팽창시키던 방식에서 기계적인 방식으로 핑거를 사용하여 바디 플라이가 턴업되도록 하여 브레다 사용에 따른 비용 및 싸이클 타임 증가 요인을 개선시켜 보다 더 진보된 제조 방식을 적용시켜 생산성 및 품질 향상을 도모함에 그 특징이 있다 That is, in the manufacturing apparatus of pneumatic vehicle tires, the primary molding drum turn-up method in the process of molding each semi-finished product in the process of inflating the existing Breda by using a finger in a mechanical manner so that the body fly is turned up Breda It is characterized by improving productivity and quality by applying more advanced manufacturing method by improving cost and cycle time increase factor.

이하 본 발명에 따른 기계식 성형 턴업 드럼에 대하여 첨부도면과 함께 상세하게 설명하기로 한다.Hereinafter, a mechanically shaped turn-up drum according to the present invention will be described in detail with the accompanying drawings.

도 3은 본 발명에 따른 기계식 성형 턴업 드럼이 구현된 설비의 실사진(實寫眞)이고, 도 4는 본 발명에 따른 기계식 성형턴업드럼의 바디플라이어셈블리의 턴업공정 순서도이다.Figure 3 is an illustration of the installation of the mechanically formed turn-up drum according to the present invention, Figure 4 is a flow chart of the turn-up process of the body pliers assembly of the mechanically formed turn-up drum according to the present invention.

본 발명에 따른 기계식 성형드럼은 턴업드럼(1)의 외주면에 원주를 따라 다수개의 턴업핑거(5)가 형성된다.In the mechanical molding drum according to the present invention, a plurality of turn-up fingers 5 are formed along the circumference of the outer peripheral surface of the turn-up drum 1.

상기 턴업핑거(5)는 도 4에서 구체적 도시함을 생략하고 있으나 봉상체로 되어 드럼축에 평행하게 일측단부가 턴업드럼(1)의 외주면에 축방향으로 슬라이딩이 가능하며 타단부가 들려지도록 회동가능하게 설치되며, 턴업핑거(5)의 상기 타단부는 구형의 핑거팁이 형성된다. 이같은 구성으로 된 상기 턴업핑거(5)는 도 4의 (a) 내지 (c)에 도시된 바와 같이 핑거팁이 턴업드럼(1)에 권취된 바디플라이어셈블리(3)의 안쪽면을 비집고 들어가고 턴업핑거(5)가 턴업드럼(1)의 외주면에서 축방향으로 슬라이딩하여 바디플라이어셈블리(3)를 턴업시켜 비드어셈블리(2)를 감싸면서 조립하도록 하는 것이다.Although the turn-up finger 5 is not shown in detail in FIG. 4, the rod-up finger 5 is a rod-shaped body, and one end of the turn-up finger is slidable in the axial direction on the outer circumferential surface of the turn-up drum 1 and rotated so that the other end is lifted. It is possible to install, the other end of the turn-up finger 5 is a spherical fingertip is formed. The turn-up finger (5) having such a configuration is turned into the turn of the finger tip of the body pliers (3) wound around the turn-up drum (1) as shown in (a) to (c) of FIG. The finger 5 is slid in the axial direction from the outer circumferential surface of the turn-up drum 1 to turn up the body pliers 3 to be assembled while wrapping the bead assembly 2.

본 발명에 따른 기계식 성형 턴업드럼은 종래의 턴업 브레다를 제거하고 그와 동일한 기능을 하는 기계장치인 턴업 핑거(Turn-Up Finger, 5)를 기존의 턴업 브레다가 형성된 부위에 설치하여 비드플라이어셈블리(3)를 턴업하도록 하고 있다.Mechanically-formed turn-up drum according to the present invention removes the conventional turn-up bred and installs a turn-up finger (Turn-Up Finger, 5) which is a mechanical device having the same function to the existing turn-up bred portion formed bead pliers assembly ( 3) to turn up.

이와같은 구성 및 작용을 하는 본 발명에 따른 기계식 성형 턴업드럼은 종래의 턴업브레다의 팽창시간에 소요되는 시간만큼 빨라지므로 그만큼 싸이클 타임 감소 및 팽창량의 불균일이 있을 수 없고, 턴업핑거에 의하여 기계적으로 턴업시키므로 써 타이어의 그린케이스의 좌우 조립 품질의 균일화로 인하여 품질의 균일성 향상과 함께 턴업브레다의 수선 및 교체에 따른 비용이 절감되는 효과를 갖는다.Mechanical forming turn-up drum according to the present invention having such a configuration and action is faster by the time required for the expansion time of the conventional turn-up Breda, so there can be no cycle time reduction and non-uniformity of the expansion amount, mechanically by the turn-up finger By turning up, the uniformity of the right and left assembly quality of the green case of the tire is improved, thereby improving the uniformity of the quality and reducing the cost of the repair and replacement of the turn-up brake.
