Abstract

A sponge roll apparatus of a molding drum for pressing a semi-product during a wind-up is provided to reduce the labor strength of a worker and improve the preciseness of an attachment position by automating a process of supplying and attaching a rim flange and a side to the molding drum. A sponge roll apparatus of a molding drum for pressing a semi-product during a wind-up attaches a rim flange to the molding drum and presses the rim flange when the semi-product is wound up by rotating the molding drum. The sponge roll apparatus includes a sponge roll(110), a roll bracket(120), and an up-down cylinder(130). The position of the sponge roll can be changed to the right or left side along a rotary shaft. The roll bracket axially supports the sponge roll in parallel to the molding drum. The up-down cylinder moves the roll bracket up and down.

본 발명은 성형드럼에 림플렌지와 사이드 반제품을 공급하여 부착하고 와인드업시 압착하는 장치에 관한 것으로 상하 이동이 가능한 스폰지롤을 구비한 성형드럼의 반제품 와인드업 압착용 스폰지롤장치에 관한 것이다.The present invention relates to a device for supplying and attaching a lim flange and a side semifinished product to a forming drum, and for crimping during winding up. The present invention relates to a sponge roll device for semi-finished windup pressing of a forming drum having a sponge roll capable of vertical movement.

공기입 타이어 특히 트럭, 버스용 공기입 타이어의 제조공정인 성형공정에 있어서, 1차 성형드럼에 타이어 반제품인 림프렌지(Rim flange)반제품과 사이드(Side)반제품을 조립하는 작업을 인력(人力)에 의존하여 반제품의 공급과 부착(Wind-up)이 이루어진다.In the molding process, which is a manufacturing process of pneumatic tires, especially pneumatic tires for trucks and buses, the work of assembling a limm flange semifinished product and side semifinished product, which is a semifinished tire, on a primary forming drum Depending on the supply and wind-up of the semifinished product is achieved.

각 타이어 반제품을 제조사양에 명시되어 있는 위치에 조립순서에 의해 공급 및 부착작업을 수작업(手作業)에 의존하여 실시 함에 따라 부착위치가 일정하지 않고 드럼에 부착(Wind-up)시 바디-플라이(Body-ply)와 림플랜지/사이드(Rim flange/side) 사이가 들뜨게 되어 최종적으로 스티칭 작업시 밀림에 의한 겹침으로 인하여 완제품 품질에 불량이 발생한다. 기본적으로 인력에 의한 수작업은 노동 강도에 따라 완제품의 품질에 영향을 미친다.As each tire semi-finished product is supplied and attached to the position specified in the manufacturer's quantity by manual assembly, the attachment position is not constant and the body-ply is attached to the drum. The gap between the body-ply and the rim flange / side is lifted up, resulting in poor quality of the finished product due to overlapping due to the rolling during stitching. Basically, manual labor by manpower affects the quality of the finished product according to the labor intensity.

아울러 성형 드럼에 각 반제품을 조립한 후 스티칭 작업을 실시하게 되는데 이때 성형드럼에 반제품이 일정한 위치에 부착되지 못하면 밀림현상이 발생한다.In addition, after assembling each semi-finished product to the forming drum, stitching is performed. If the semi-finished product is not attached to the forming drum at a predetermined position, a rolling phenomenon occurs.

본 발명의 목적은 성형드럼에 림프렌지와 사이드를 공급하여 부착하는 공정을 자동화시켜 작업자의 노동강도를 줄이고 부착위치에 대한 정밀도를 향상시키어 품질향상을 도모하고자 함에 그 특징이 있다.An object of the present invention is to automate the process of supplying and attaching the lymph range and the side to the forming drum to reduce the labor intensity of the operator and to improve the accuracy of the attachment position to improve the quality.

본 발명에 따른 성형드럼의 반제품 와인드업 압착용 스폰지롤장치는 성형드럼 상단에 위치한 림프렌지 공급용 서비서 전단에 분리형 스폰지롤을 형성시키고, 림프렌지 반제품과 사이드 반제품을 상기 림프렌지 공급용 서비서가 성형드럼에 공급하면 스폰지롤이 하강하여 회전되는 성형드럼위에 와인드-업되는 상기 반제품을 일정한 압력으로 압착하여 성형드럼에 부착하도록 구성됨을 특징으로 한다.Sponge roll device for pressing the semi-finished product wind-up of the forming drum according to the present invention forms a separate sponge roll on the front end of the lymphangular supply service provider located on the top of the forming drum, and the lymphangular semifinished product and the side semifinished product are molded by the lymphangular supply service provider. When supplied to the drum is characterized in that it is configured to adhere to the forming drum by pressing the semi-finished product which is wind-up on the forming drum is rotated by rotating the sponge roll at a constant pressure.

상기한 바와 같은 구성으로 이루어진 본 발명에 따른 성형드럼의 반제품 와인드업 압착용 스폰지롤장치에 대하여 이하 첨부도면과 함께 상세하게 설명하기로 한다.The sponge roll device for semi-finished wind-up pressing of the forming drum according to the present invention having the configuration as described above will be described in detail with the accompanying drawings.

단, 본 명세서 및 청구범위에 사용된 용어나 단어는 발명자가 본 발명을 설명하기 위한 최선의 방법으로 선택한 개념으로 간주하고 본 발명의 기술적 내용을 파악함에 있어서 본 발명의 기술적 사상에 부합한 의미와 개념으로 적절히 해석되어야 할 것이다.However, the terms or words used in the present specification and claims are regarded as concepts selected by the inventors as the best way to explain the present invention and the meanings consistent with the technical spirit of the present invention in grasping the technical contents of the present invention. It should be properly interpreted as a concept.
