Description

롤러를 구성하기 위한 샤프트와 파이프부재의 결합장치{Shaft and pipe materials combination apparatus for constitute roller}[0001] The present invention relates to a shaft and a pipe member,

본 발명은 롤러를 구성하기 위한 샤프트와 파이프부재의 결합장치에 관한 것이다. 상세하게 본 발명은, 필름형태 원단의 피딩(feeding)이나 기타 제품의 이송을 위해 마련되는 롤러의 구성에서 회전축이 되는 샤프트와, 롤러의 외주면을 형성하는 파이프부재가 보다 견고하게 결합될 수 있도록 하고, 롤러 구성의 조립이 보다 손쉽게 실시될 수 있도록 한 샤프트와 파이프부재의 결합장치에 관한 것이다.
The present invention relates to a coupling device of a shaft and a pipe member for constituting a roller. More particularly, the present invention relates to a roller assembly for feeding a film-form fabric or for conveying other products, a shaft serving as a rotary shaft, and a pipe member forming an outer circumferential surface of the roller, The present invention relates to a coupling device of a shaft and a pipe member so that assembly of a roller configuration can be performed more easily.

여러 산업분야에서 사용되어지고 있는 롤러는 주로 필름형태로 된 원단의 진행각도를 전환시켜 피딩되도록 하거나, 제품을 이송하기 위한 컨베이어 등에 주로 사용되어지고 있다.The rollers used in various industrial fields are mainly used for conveying the products by feeding the products by changing the progress angle of the raw material in the form of film.

이와 같은 롤러는 길이방향을 갖는 원통형태로 상당한 크기로 제작될 경우 구성의 경량화 및 소재의 절감을 위해 내부에 중공이 형성된 파이프 형태의 부재(이하, 파이프부재)로 제작되며, 상기 파이프부재의 회전축으로 샤프트가 결합되어 구성된다.Such a roller is made of a pipe-shaped member (hereinafter, referred to as a pipe member) having a hollow inside to reduce the weight and material of the pipe when the pipe is manufactured in a considerable size in a cylindrical shape having a longitudinal direction, As shown in Fig.

특히, 상기 롤러는 컨베이어 등과 같이 제품의 단순한 이동시에는 샤프트와 파이프부재의 결합상태가 정밀하지 않아도 작업을 진행할 때 크게 문제가 발생되지 않지만, 필름형태로 된 원단의 진행, 보다 구체적으로 정밀회로의 인쇄회로기판으로 사용되는 FPCB(연성회로기판)의 표면처리를 실시하기 위해 진행각도를 전환시키며 피딩하기 위한 롤러는 샤프트와 파이프부재 간의 상당한 결합정밀도를 요구하고 있다.
Particularly, when the product is simply moved, such as a conveyor, the roller does not cause a serious problem when the operation is performed even though the state of engagement between the shaft and the pipe member is not precise, but the progress of the fabric in the form of a film, The rollers for feeding and feeding advancing angles to perform the surface treatment of the FPCB (flexible circuit board) used as the circuit board require a considerable coupling accuracy between the shaft and the pipe member.

대한민국 특허출원 제2006-29273호(기판이송용 샤프트의 롤러 결합장치, 이하, 기출원발명1)과, 대한민국 실용신안등록출원 제2006-9271호(컨베이어용 롤러, 이하 기출원발명2)에는 전술된 샤프트에 파이프부재를 결합시키기 위한 구성이 제시되고 있다.Korean Patent Application No. 2006-29273 (a roller coupling device for a substrate transferring shaft, hereafter referred to as original invention 1) and Korean Utility Model Registration Application No. 2006-9271 (conveyor roller, hereinafter referred to as original invention 2) There is proposed a configuration for coupling the pipe member to the shaft.

상기 기출원발명1은 결합수단으로 부시형태의 단일부재를 샤프트와 파이프부재의 사이에 결합되도록 한 구성이기 때문에 샤프트가 회전될 때 슬립발생 및 상기 결합수단이 손쉽게 마모되는 문제점이 노출된다.In the present invention, since the bush-shaped single member is coupled between the shaft and the pipe member as the coupling means, the problem of slip occurrence and the abrasion of the coupling means is exposed when the shaft is rotated.

또한, 상기 기출원발명2는 기출원발명1에 비해 결합수단이 견고한 구성으로 제안되기는 하지만, 결합수단과 파이프부재 간의 결합이 용접에 의해 실시되고, 베이링 등을 수용해야 하는 구성에 의해 결합수단이 상당히 복잡한 형상으로 가공되어야 하기 때문에 제작이 번거로운 문제점이 발생된다.
In addition, although the inventive invention 2 is proposed in comparison with the original invention 1, the coupling means is provided with a rigid structure, but the coupling between the coupling means and the pipe member is performed by welding, It is required to be processed into a considerably complicated shape, which results in troublesome fabrication.

A receiving groove 21 is formed in the inner circumferential surface of the pipe member 2 so as to receive the presser ring 20 coupled with the inner circumferential surface of the pipe member 2 at a position corresponding to the outer circumferential diameter of the presser ring 20, A housing 30 formed to have a diameter corresponding to that of the pipe member 2 and fitted to the inner circumferential surface of the pipe member 2;
The pressing ring 20 coupled to the receiving groove 21 of the housing 30 is detachably engaged with the housing 30 by closing the receiving groove 21 of the housing 30, A housing cover (40) for providing a pressing force for pressing the contact ring (10) coupled with the shaft (20) to the shaft (1);
Lt; / RTI >
The pressing ring 20 is formed with a cutting slit S on one side thereof so as to have an elastic force when the contact ring 10 is pressed by the housing cover 40,
A protrusion 41 having an outer diameter corresponding to the inner diameter of the receiving groove 21 of the housing 30 is protruded toward the pressing ring 20 and is firmly attached to the housing 30 when the pressing ring 20 is engaged with the housing 30. [ And is pressurized,
If the pressurizing ring 20 is brought into close contact with the housing cover 40 when the housing cover 40 is engaged with the housing 30 in a state where a combination of the contact ring 10 and the presser ring 20 is inserted into the housing 30, The inclined surface T of the outer periphery of the contact ring 10 is pressed by the inner circumferential inclined surface T of the contact ring 10 to keep the inner circumferential surface of the contact ring 10 firmly in contact with the outer circumferential surface of the shaft 1 Wherein the shaft and the pipe member constitute a roller. 삭제delete 삭제delete
