Description

스트립 변형방지를 위한 페스투너의 구조{A Structure of Festooner for Preventing Strip Transformation}Structure of Festooner for Preventing Strip Transformation

본 발명은 타이어 제조시 사용되는 스트립의 변형을 방지하기 위한 페스투너에 관한 것으로, 특히 롤러를 회전시키는 체인이 구비됨과 동시에 롤러상에 꼬임벨트가 설치되어, 상기 체인의 회전에 의해 구동되는 롤러를 통해 스트립의 변형을 방지하고, 상기 스트립이 꼬임벨트상에서 이송되도록 하여 스트립 표면의 변형도 방지할 수 있도록 된 스트립 변형방지를 위한 페스투너의 구조에 관한 것이다.The present invention relates to a fastener for preventing the deformation of the strip used in the manufacture of tires, and in particular, a chain for rotating the roller and at the same time a twist belt is installed on the roller, driven by the rotation of the chain The present invention relates to a structure of a fastener for preventing deformation of a strip through which the deformation of the strip is prevented and the strip is transported on the twist belt to prevent deformation of the strip surface.

일반적으로 타이어 제조공정 중에는 재료의 두께가 얇은 형태인 스트립(Strip)을 생산 혹은 어셈블리(Assembly)하거나, 권취된 상태로 다음 공정으로 보내서 후속작업을 연계하도록 된 작업형태를 흔히 찾아 볼 수 있다.In general, during the tire manufacturing process, it is common to find a form of work in which a strip of thin material is produced or assembled, or wound and sent to the next process to link subsequent work.

여기서 상기 어셈블리되는 재료들의 작업공정을 살펴보면, 서로 다른 재료가 하나의 컨베이어(Conveyor)상으로 이송되면서 작업이 이루어지므로 서로 다른 재료간의 속도조절 및 재료교체 등을 감안하여 각각의 재료들을 일정량만큼 미리 저장해 두었다가 사용하도록 하여 공정에 차질이 발생하는 것을 방지하고 있는데, 이렇듯 공급되는 재료들의 속도조절 및 재료교체 등을 위한 저장장치를 페스투너(Festooner)라고 한다.Looking at the working process of the materials to be assembled here, since the work is carried out while the different materials are transported on a conveyor (Conveyor), in consideration of the speed control and material replacement between different materials to store a predetermined amount of each material in advance By putting it in and using it to prevent the process from occurring, the storage device for speed control and material replacement of the supplied materials is called a festooner.

상기 페스투너의 일반적인 형태를 살펴보면, 공급되는 재료의 자중을 이용한 방식과 웨이트밸런싱(Weight Balancing) 방식으로 나눠볼 수 있는데, 이중 재료자체의 중량을 이용한 방식의 경우에는 도 3 내지 도 4에서 보는 바와 같이, 다수개의 롤러(101)들이 상/하로 배치되고, 이 롤러(101)들이 수직방향으로 일정거리만큼 이동될 수 있도록 구성되어, 재료 공급속도가 평상시일 경우에는 상기 롤러(101)들 사이에 저장된 재료(102)가 평상속도로 공급되다가, 재료 공급속도가 빨라지면 롤러(101)들 사이의 재료(102)가 빨리 끌려나가면서 인접한 롤러(101)들을 끌어당기는 힘이 발생되고, 이 힘에 의해 상/하부의 롤러(101)들이 수직방향(↕으로 도시됨)으로 이동되면서 재료(102)에 가해지는 인장력을 상쇄하게 된다.Looking at the general form of the fastener, it can be divided into the method using the weight of the material supplied and the weight balancing (Weight Balancing) method, in the case of the method using the weight of the double material itself as shown in Figures 3 to 4 Likewise, a plurality of rollers 101 are arranged up and down, and the rollers 101 are configured to be moved by a predetermined distance in the vertical direction, so that the material is supplied between the rollers 101 in the usual case. The stored material 102 is supplied at a normal speed, and when the material supply speed is increased, the material 102 between the rollers 101 is quickly pulled to generate a force that pulls adjacent rollers 101, and by this force The upper and lower rollers 101 are moved in the vertical direction (shown in Fig.) To offset the tension applied to the material 102.

이에 따라 상기 페스투너는 공급되는 재료의 임시적인 저장장치로서의 역할과 속도조절의 기능을 수행할 수 있게 된다.Accordingly, the fastener can serve as a temporary storage device for the material to be supplied and perform a function of speed control.

한편, 상기 웨이트밸런싱 방식 페스투너의 경우에는, 하부 롤러의 자중으로 인한 공급재료의 물리적 변형을 방지하기 위해 카운터밸런스웨이트(Count Banlance Weight)를 추가 장착하여 하부롤러의 중량을 감소시켜 공급되는 재료의 늘어남과 같은 물리적 변형을 방지하도록 구성되어 있다.Meanwhile, in the case of the weight balancing type fastener, a counter balance weight is additionally installed to prevent physical deformation of the feed material due to the weight of the lower roller, thereby reducing the weight of the lower roller. It is configured to prevent physical deformation such as stretching.

그러나 투입되는 재료인 스트립의 폭 및 두께의 유지가 중요한 공정의 경우나 스트립의 두께가 0.5mm ~ 1.0mm인 스트립 고무의 경우에는 작은 요인변화에도 민감하여 재료의 변형을 초래하기 때문에 종래와 같은 페스투너를 사용할 경우에는 스트립의 변형을 극복하기 어려운 문제점이 있었다.However, in the case of a process where the maintenance of the width and thickness of the input material strip is important, or in the case of strip rubber having a strip thickness of 0.5 mm to 1.0 mm, it is sensitive to small factor changes and causes deformation of the material. In the case of using the stretcher, there was a problem in that it was difficult to overcome deformation of the strip.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 지지프레임의 상부와 하부에 다수개의 롤러가 구비되고, 이 롤러의 회전축상에 스프로킷이 장착되며, 이 스프로킷에 체인이 설치되는 한편, 상기 롤러들 사이에 한번 꼬아진 형태의 벨트가 설치되어, 이 벨트상으로 스트립이 공급되고, 상기 체인이 구동모터에 의해 작동되면서 롤러를 회전시켜 상기 벨트상에 얹혀진 스트립을 이송하도록 하여, 롤러의 자중과 재료 공급속도의 차이로 인해 스트립에 가해지는 변형을 방지함은 물론, 스트립이 롤러와 직접 접촉되는 것을 방지하여 부가적인 변형도 방지할 수 있도록 된 스트립 변형방지를 위한 페스투너의 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, a plurality of rollers are provided on the upper and lower portions of the support frame, the sprocket is mounted on the rotation axis of the roller, the chain is installed on the sprocket, A belt of a twisted form is installed between the rollers, and the strip is supplied onto the belt, and the chain is operated by the driving motor to rotate the roller to transfer the strip mounted on the belt. It provides a structure of a fastener to prevent deformation of the strip, which prevents the deformation of the strip due to the difference in self-weight and the material feeding speed, and also prevents the strip from coming into direct contact with the roller. Its purpose is to.

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명에 따른 페스투너의 측면도이고, 도 2 는 본 발명의 요지인 체인과 롤러 및 꼬임벨트의 구성을 나타내는 사시도로서, 본 발명은 지지프레임(1)의 상/하부에 다수개의 롤러(2)가 설치되고, 이 롤러(2)들 사이로 스트립(5)이 공급되도록 된 페스투너의 구조에 있어서, 상기 롤러(2)의 회전축(2a)상에 스프로킷(6)이 장착되고, 이 스프로킷(6)에 체인(7)이 연결되는 한편, 상기 롤러(2)의 외주면을 감싸도록 한번 꼬여진 형태의 꼬임벨트(8)가 설치되어 이루어진다.Figure 1 is a side view of the fastener according to the invention, Figure 2 is a perspective view showing the configuration of the chain and roller and the twist belt which is the subject of the present invention, the present invention is a plurality of rollers on the upper / lower portion of the support frame (1) In the structure of the fastener in which (2) is provided and the strip 5 is supplied between the rollers 2, the sprocket 6 is mounted on the rotation shaft 2a of the roller 2, and While the chain 7 is connected to the sprocket 6, a twist belt 8 having a twisted shape is formed to surround the outer circumferential surface of the roller 2.

여기서, 상기 체인(7)은 구동모터(3,4)와 연결되어 동력을 전달받으며, 상기 꼬임벨트(8)의 재질은 공급되는 스트립(5)과 접촉력이 우수한 재질이 사용된다.Here, the chain 7 is connected to the drive motors 3 and 4 to receive power, and the material of the twist belt 8 is made of a material having excellent contact force with the supplied strip 5.

이에 따라, 상기 구동모터(3,4)에 의해 체인(7)이 회전됨과 동시에 롤러(2)가 연동되어 회전되고, 이에 따라 이 롤러(2)에 설치된 꼬임벨트(8) 상으로 공급되는 스트립(5)이 작업공정으로 투입된다.Accordingly, the chain 7 is rotated by the drive motors 3 and 4, and the roller 2 is interlocked and rotated, and thus the strip is supplied onto the twist belt 8 installed in the roller 2. (5) It is put into work process.

여기서, 상기 꼬임벨트(8)는 한번 꼬여진 형태로 롤러(2)들 사이에 설치되므로 공급되는 재료인 스트립(5)의 외면만 접촉될 뿐 내면은 접촉되지 않게 되어, 스트립(5)의 내면이 접촉되면서 발생할 수 있는 변형을 방지할 수 있다.Here, since the twist belt 8 is installed between the rollers 2 in a twisted form, only the outer surface of the strip 5, which is a supplied material, is contacted, and the inner surface is not in contact with the inner surface of the strip 5. It is possible to prevent the deformation that may occur during contact.

아울러, 상기 체인(7)의 구동력에 의해 롤러(2)가 작동되므로 재료에 가해지는 인장력을 배제시킬 수 있어, 스트립(5)이 외력에 의해 변형되는 것을 방지할 수 있게 된다.In addition, since the roller 2 is operated by the driving force of the chain 7, it is possible to exclude the tensile force applied to the material, it is possible to prevent the strip 5 from being deformed by the external force.

이상 설명한 바와 같이 본 발명에 따르면, 롤러의 회전축상에 스프로킷이 장착되고, 이 스프로킷에 체인이 설치되는 한편, 상기 롤러들 사이에 한번 꼬아진 형태의 꼬임벨트가 설치되어, 공급되는 스트립이 체인의 구동력에 의해 공급되므로 스트립 변형을 방지하고 한번 꼬여진 형태로 공급되므로 스트립의 내면에 가해질 수 있는 부가적인 변형도 방지할 수 있는 효과가 있다.As described above, according to the present invention, a sprocket is mounted on the rotating shaft of the roller, and a chain is installed on the sprocket, and a twist belt of a twisted form is installed between the rollers, so that the supplied strip is Since it is supplied by the driving force, it prevents the deformation of the strip and is supplied in the twisted form, thereby preventing the additional deformation that may be applied to the inner surface of the strip.
