Description

래디얼타이어의 벨트보강재 공급장치Belt reinforcement supply device of radial tire

본 발명은 래디얼타이어의 구성재료인 스틸벨트에 부착되는 보강재를 공급하는 장치에 관한 것으로, 특히 스틸벨트 재단기의 운행중단없이 연속적인 생산이 가능하도록 하여 생산성 및 작업성을 향상시킨 래디얼타이어의 벨트보강재 공급장치에 관한 것이다.The present invention relates to a device for supplying a reinforcing material attached to a steel belt, which is a constituent material of a radial tire, and in particular, a belt reinforcing material of a radial tire that improves productivity and workability by allowing continuous production without stopping the steel belt cutting machine. It relates to a supply device.

일반적으로, 래디얼타이어의 구성재료 중의 하나인 스틸벨트는 타이어의 형상을 유지하고 내구적 기능을 갖는데, 이 스틸벨트는 다른 재료보다 타이어 전체중량에 있어서 큰 비중을 차지하여 타이어의 경량화를 위해 점차 스틸벨트의 두께를 줄이도록 노력하고 있는 바, 통상 타이어를 경량화시킴과 동시에 그 내구성을 종전대로 유지하도록 일정한 보강재를 사용하는데, 이 보강재는 스틸벨트 양측면에 고무스트립 형태로 부착된다.In general, the steel belt, which is one of the constituent materials of the radial tire, maintains the shape of the tire and has a durable function. The steel belt occupies a larger proportion in the total weight of the tire than other materials, and gradually increases the weight of the tire to reduce the weight of the tire. Efforts have been made to reduce the thickness of the belt. In order to reduce the weight of the tire and maintain its durability as usual, a constant reinforcement is used, which is attached to both sides of the steel belt in the form of a rubber strip.

상기 보강재의 부착방법을 좀 더 자세히 살펴보면, 도 10 내지 도 11 에서 보는 바와 같이, 재단기(101)의 중앙부에 설치되는 프레임(102)의 상단에 회전되는 축(103)이 구비되고, 이 축(103)에 별도의 설비에서 폭 25mm 스트립 형태로 권취되어 롤(roll)형태로 된 2개의 보강재(104)가 장착되고, 상기 재단기(101)의 운반롤러를 타고 이송되는 스틸벨트(105)의 양단에 상기 보강재(104)가 안내롤러(106)을 거치면서 부착된다.Looking at the attachment method of the reinforcing material in more detail, as shown in Figure 10 to 11, the shaft 103 is provided on the top of the frame 102 is installed in the center of the cutting machine 101 is provided, this shaft ( Both ends of the steel belt 105, which is rolled in a strip shape of 25 mm width in a separate facility in the separate equipment 103, is mounted in a roll form, and is transported by a conveying roller of the cutting machine 101. The reinforcing material 104 is attached to the guide roller 106 while passing through.

그러나, 종래의 보강재 공급장치는 권취된 보강재가 다 풀리게 되면 새로운 롤 형태의 보강재를 축에 교체해야 하기 때문에 재단기의 작동을 중지한 후 교체작업을 마치고 다시 재단기를 작동하여 스틸벨트에 보강재를 부착해야 하므로 설비가동률, 작업성 등이 저하되는 문제점이 있었다.However, in the conventional reinforcement supply device, when the wound reinforcement is loosened, a new roll-shaped reinforcement must be replaced on the shaft. Therefore, after the operation of the cutting machine is stopped, the replacement work is completed, and the cutting machine is operated to attach the reinforcement to the steel belt. Therefore, there was a problem that the facility operation rate, workability, etc. are lowered.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 종래의 스트립 폭에 비해 2배의 폭으로 절단되어 축에 권취된 보강재가 일정한 형태의 저장공간을 경유하여 컷터에 의해 2분할되어 스틸벨트에 부착되는 한편, 권취된 보강재의 교체시에는 저장공간의 롤러가 이동되어 저장공간의 폭이 축소됨에 따라 보강재의 교체시간 동안에 필요한 공급량을 충당하도록 되어, 재단기의 운행중단없이 스틸벨트와 보강재의 부착작업이 연속적으로 이루어지도록 된 래디얼타이어의 벨트보강재 공급장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the reinforcing material is cut into two times the width of the conventional strip width wound in the shaft is divided into two by a cutter through a storage space of a certain form of steel When it is attached to the belt, when the wound reinforcement is replaced, the roller of the storage space is moved so that the width of the storage space is reduced so as to cover the necessary supply during the replacement time of the reinforcement. It is an object of the present invention to provide a belt reinforcing material supply device of a radial tire, which is to be continuously attached.

이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.

본 발명은 상기 렛오프유니트(1)의 축(1d)에 50mm 폭의 제1보강재(6)가 양측에 각각 설치되고, 상기 페스투너(2)의 에어실린더(2c)를 작동시키면 상부측에 설치된 롤러(2b)가 하강되어 작업자가 제1보강재(6)를 롤러에 걸기 용이한 높이로 조절된다.In the present invention, the first reinforcing material 6 having a width of 50 mm is installed on both sides of the shaft 1d of the let-off unit 1, and when the air cylinder 2c of the fastener 2 is operated, The roller 2b installed in the lowering is adjusted so that the worker can easily fasten the first reinforcing material 6 to the roller.

이후, 상기 제1보강재(6)가 구동모터(2g)의 회전에 따라 페스투너(2)쪽으로 풀려지면서 다수개의 롤러를 번갈아 경유하여 상/하부컷터(3a,3b)의 블레이드(3c)에 의해 2분할된 후, 안내부(4)의 상/하부롤러(4e,4f)와 회전롤러(4b)를 통해 재단기(5)쪽으로 공급되며, 이후 안내롤러(5a)에 의해 스틸벨트의 양단에 부착된다.Thereafter, the first reinforcing material 6 is released toward the fastener 2 as the driving motor 2g rotates, and alternately passes through a plurality of rollers to the blades 3c of the upper and lower cutters 3a and 3b. After being divided by two, it is supplied to the cutting machine 5 through the upper and lower rollers (4e, 4f) and the rotating roller (4b) of the guide portion 4, and then to both ends of the steel belt by the guide roller (5a) Attached.

여기서, 상기 제1보강재(6)가 모두 풀려져서 그 끝단이 렛오프유니트(1)의 상단에 설치된 제1,2센서(1e,1f)를 통과하게 되면, 이 제1,2센서(1e,1f)에서 제1보강재(6)의 교체시기를 파악하게 되고, 이 제1,2센서(1e,1f)의 신호에 의해 상기 그립퍼(2a)가 제1보강재(6)의 끝단을 잡아주게 된다.Here, when all of the first reinforcing material 6 is released and the end passes through the first and second sensors 1e and 1f installed at the upper end of the let-off unit 1, the first and second sensors 1e, In 1f), the timing of replacing the first reinforcement 6 is determined, and the gripper 2a grasps the end of the first reinforcement 6 by the signals of the first and second sensors 1e and 1f. .

이에 따라, 제1보강재(6)의 공급은 중지되나 상기 렛오프유니트(1)를 제외한 나머지 부분은 지속적으로 작동되므로 제1보강재(6)의 공급길이가 단축되고, 결과적으로 제1보강재(6)가 페스투너(2)의 하부측 롤러(2b)를 끌어올리는 장력이 발생되어 이 롤러(2b)가 가이드(2d)를 매개로 상부로 미끄럼 이동되는 한편, 상기 렛오프유니트(1)의 에어실린더(1c)가 작동하여 여유분의 제2보강재(6a)가 장착된 축이 렛오프유니트(1)의 롤러(1a)쪽으로 이동되고, 수작업에 의해 새로 공급되는 제2보강재(6a)의 시작부 끝단과 상기 그립퍼(2a)에 물려진 제1보강재(6)의 끝단을 연결하여 주게 된다.As a result, the supply of the first reinforcing material 6 is stopped, but the remaining portion of the first reinforcing material 6 is shortened because the remaining portions except the let-off unit 1 are continuously operated, and as a result, the first reinforcing material 6 Tension is generated to raise the lower roller 2b of the fastener 2 so that the roller 2b slides upward through the guide 2d, The air cylinder 1c is operated to move the shaft on which the spare second reinforcement 6a is mounted to the roller 1a of the let-off unit 1, and to start the second reinforcement 6a newly supplied by hand. The end portion of the first reinforcing material (6) bite to the gripper (2a) is connected.

여기서, 상기 페스투너(2)의 롤러(2b)의 높이가 2미터이므로 롤러(2b)사이에 저장된 제1보강재(6)의 길이는 32미터에 해당되고, 상기 재단기(5) 스틸벨트의 평균 이송속도인 32엠피엠(mpm ; meter per minute)으로 스틸벨트가 이송되면 약 1분간의 여유시간이 생기며 이 시간에 새로운 제1보강재를 다시 걸 수 있게되고, 공급이 재개되면 초기 제2보강재(6a)의 공급속도가 빨라지면서 제2보강재(6a)의 장력이 낮아지므로 상기 페스투너(2)의 하부측 롤러(2b)가 원위치로 하강되어 제2보강재(6a)의 저장공간을 다시 확보할 수 있게 된다.Since the height of the roller 2b of the fastener 2 is 2 meters, the length of the first reinforcing material 6 stored between the rollers 2b corresponds to 32 meters, and the length of the steel belt of the cutter 5 When the steel belt is transported at an average feed rate of 32 MPM (mpm per minute), there will be a spare time of about 1 minute, at which time the new first stiffener can be re-hung, and when the supply resumes, the initial second stiffener Since the tension of the second reinforcing material 6a is lowered as the feeding speed of 6a becomes faster, the lower roller 2b of the fastener 2 is lowered to its original position, thereby reserving the storage space of the second reinforcing material 6a. It can be secured.

그리고, 안내부(4)에 설치된 댄서부(4a)는 수직으로 고정된 로드(4g)을 따라 상하이동하여 일정한 여유공간을 형성할 수 있도록 하여 2분할된 제1보강재(6)가 이송중에 장력차이로 인해 발생될 수 있는 제1보강재(6)의 이송 불균일성을 해소하게 된다.Then, the dancer portion 4a installed in the guide portion 4 moves along the vertically fixed rod 4g so as to form a certain free space, so that the first divided reinforcement 6 divided into two is tensioned during transportation. This eliminates the transfer nonuniformity of the first reinforcement (6) that may occur due to the difference.

이상 설명한 바와 같이 본 발명에 따르면, 렛오프유니트와 페스투너, 컷팅부 및 안내부로 이루어진 제1보강재 공급장치가 재단기의 일측에 설치되어, 이 재단기에 의해 이송되는 스틸벨트의 양측에 상기 공급장치를 통해 재단기의 운행중단 없이 연속적인 부착이 가능하도록 되어, 설비가동률 및 작업성을 향상시키는 효과가 있다.As described above, according to the present invention, a first reinforcing material supply device comprising a let-off unit, a fastener, a cutting part, and a guide part is installed on one side of the cutting machine, and the supply device is provided on both sides of the steel belt conveyed by the cutting machine. Through it is possible to continuously attach without interrupting the cutting machine, there is an effect to improve the equipment operation rate and workability.
