Description

타이어 반제품의 스플라이스 커팅장치{A Splice Cutter of Half-Finished Tires}Splice Cutter of Half-Finished Tires

본 발명은 타이어 반제품의 스플라이스 커팅장치에 관한 것으로서, 특히 타이어 반제품을 일정 길이만큼 자동으로 절단하는 타이어 반제품의 스플라이스 커팅장치에 관한 것이다.The present invention relates to a splice cutting device for semi-finished products, and more particularly, to a splice cutting device for semi-finished tire products for automatically cutting tire semi-finished products by a predetermined length.

도 1에는, 압출된 타이어 반제품이 절단 및 권취되는 생산 라인의 구성이 도시되어 있다.1 shows the construction of a production line in which an extruded tire semifinished product is cut and wound.

도시된 바와 같이, 압출기(11)에서 압출이 완료된 타이어 반제품(12)은 컨베이어(1)에 의해 이송되며, 쿨링드럼(Cooling Drum, 7)을 통해 냉각된 후, 절단작업이 이루어진다. 일정길이로 절단된 타이어 반제품은 권취기(Winding M/C, 9)에 의해 감겨진다.As shown, the tire semi-finished product 12, the extrusion is completed in the extruder 11 is transported by the conveyor (1), cooled through a cooling drum (7), and then a cutting operation is made. Tire semi-finished products cut to length are wound by a winding machine (9).

이 때, 상기 압출 완료된 타이어 반제품을 일정길이만큼 절단하기 위해서는 통상 다음과 같은 방법들이 이용된다.At this time, the following methods are commonly used to cut the extruded tire semi-finished product by a certain length.

먼저, 회전 칼날이 컨베이어(1)와 동일한 속도로 라인 진행방향으로 이송하면서 타이어 반제품을 절단하는 방법이 있다.First, there is a method of cutting a semi-finished product while the rotary blade is transferred in the line traveling direction at the same speed as the conveyor (1).

다음으로, 타이어 반제품을 컨베이어로 이송한 후, 타이어 반제품을 길게 늘어 뜨려서 절단하는 동시에, 선단 컨베이어 속도의 2배 이상의 속도로 타이어 반제품을 끌어당겨서 이송하는 방법이 있다.Next, after the semi-finished product is transported to the conveyor, the semi-finished tire is stretched and cut at the same time, and at the same time, the semi-finished product is pulled and conveyed at a speed more than twice the speed of the tip conveyor.

또는, 커터 앞에서, 컨베이어의 속도와 동일한 속도로 롤(Roll)을 피스톤으로 들어 올려서 타이어 반제품을 절단한 후, 다시 천천히 내려오도록 하는 방법이 있다.Alternatively, in front of the cutter, there is a method of cutting a semi-finished product by lifting a roll with a piston at the same speed as the speed of the conveyor, and then slowly descending again.

그러나, 이러한 방법들은, 타이어 반제품의 자중에 의해 타이어 반제품이 늘어나는 문제점이 있고, 빠른 속도로 당겨질 때는 인장력을 받아 타이어 반제품이 늘어나게 되므로 자체의 변형이 생기게 되는 문제점이 있다.However, these methods have a problem in that the semi-finished product is increased by the weight of the semi-finished product, and when the tire is pulled at a high speed, the semi-finished product is stretched under tension, thereby causing its own deformation.

본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 발명의 목적은 반제품을 잡아당기지 않고도 자동적으로 일정길이만큼 절단하여 반제품의 불량을 최소화 할 수 있는 타이어 반제품의 스플라이스 커팅장치를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a splice cutting device for semi-finished products that can minimize the defect of the semi-finished product by automatically cutting by a certain length without pulling the semi-finished product.

상기한 목적을 달성하기 위해, 본 발명에 따른 타이어 반제품의 스플라이스 커팅장치는,In order to achieve the above object, a splice cutting device for semi-finished products according to the present invention,

컨베이어의 측면에 설치된 엔코더(Encoder)와;An encoder installed on the side of the conveyor;

상기 엔코더로부터 신호를 받아 구동되는 회전제어구동부와;A rotation control driving unit driven by receiving a signal from the encoder;

상기 회전제어구동부에 결합되어 회전하는 회전롤(Roll)과;A rotation roll coupled to the rotation control driving unit and rotating;

상기 회전롤의 둘레에 설치된 커터;A cutter installed around the rotary roll;

를 포함하여 구성되는 것을 특징으로 한다.Characterized in that comprises a.

여기서, 상기 커터는 상기 회전롤의 둘레방향으로 등간격으로 2개 이상 설치되는 것이 바람직하다.Here, it is preferable that two or more cutters are installed at equal intervals in the circumferential direction of the rotary roll.

더욱이, 상기 커터에는 전열선이 연결되어 있는 것이 바람직하다.Moreover, it is preferable that a heating wire is connected to the cutter.

이하, 첨부도면을 참조하여 본 발명의 바람직한 일 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에 본 발명에 따른 타이어 반제품의 스플라이스 커팅장치의 일 예가 도시되어 있다.2 shows an example of a splice cutting device for semi-finished tire products according to the present invention.

도시된 바와 같이, 본 발명에 따른 타이어 반제품의 스플라이스 커팅장치는, 컨베이어(1)의 측면에 설치된 엔코더(Encoder, 2) 또는 속도 측정센서와, 상기 엔코더(2)로부터 신호를 받아 구동되는 회전제어구동부(3)와, 상기 회전제어구동부(3)에 결합되어 회전하는 회전롤(Roll, 4)과, 상기 회전롤(4)의 둘레에 설치된 커터(6)를 포함하여 구성되어 있다. 이를 보다 구체적으로 살펴보면 다음과 같다.As shown, the splice cutting device for semi-finished tire products according to the present invention, the encoder (Encoder 2) or a speed measuring sensor installed on the side of the conveyor (1), and the rotation driven by receiving a signal from the encoder (2) It comprises a control drive unit 3, a rotating roll (Roll, 4) coupled to the rotation control drive unit 3 and rotates, and a cutter 6 provided around the rotary roll (4). Looking at this in more detail as follows.

상기 엔코더(2)는, 컨베이어(1)의 측면에 설치되어 그 이송속도를 감지한다. 이는, 감지된 이송속도에 대응하는 펄스(Pulse)를 발생시켜서 회전제어구동부(3)에 전달하는 매우 통상적인 구성요소이다.The encoder (2) is installed on the side of the conveyor (1) to detect the transfer speed. This is a very common component that generates a pulse corresponding to the sensed feed rate and delivers it to the rotation control drive section 3.

상기 회전제어구동부(3)는 제어부와 모터부로 나뉘어져서 구성되어 있다. 제어부에서는 상기 전기적 펄스신호를 받아 기계적 신호로 변환시키며, 이 기계적 신호를 받아 모터부가 회전구동된다. 모터부는 일반적인 DC 모터 또는 AC 모터를 사용할 수 있다.The rotation control drive unit 3 is divided into a control unit and a motor unit. The control unit receives the electrical pulse signal and converts it into a mechanical signal, and the motor unit rotates in response to the mechanical signal. The motor unit may use a general DC motor or AC motor.

후술하는 커터(6)가 타이어 반제품을 일정 길이씩 절단하기 위해서는, 컨베이어(1)의 이송속도에 대응하여 회전제어구동부(3)가 회전구동되는 시점(시간)이 결정되어야 한다. 따라서, 컨베이어(1)의 이송속도의 감지시로부터 일정시간이 경과한 후, 상기 회전제어구동부(3)가 회전구동되도록 할 수 있다. In order for the cutter 6 to be described later to cut the tire semi-finished product by a predetermined length, a time point (time) at which the rotation control driver 3 rotates in response to the conveying speed of the conveyor 1 must be determined. Therefore, after a predetermined time has elapsed from the detection of the conveying speed of the conveyor 1, the rotation control driver 3 can be driven to rotate.

한편, 도 2와 도 3에 나타낸 바와 같이, 상기 회전제어구동부(3)에는, 타이밍 벨트(8)와 같은 전동(傳動) 수단을 통해 회전롤(Roll, 4)이 설치되어 있다. 그리고, 상기 회전롤(4)의 둘레에는 커터(6)가 등간격으로 설치되어 있다. 이는, 일체로 형성되어도 되고, 볼트나 나사 등의 일반적인 체결수단에 의해 결합되어도 좋다. 이에 따라, 상기 회전제어구동부(3)가 회전하면 상기 회전롤(4)이 연동되어 회전한다. 이 때, 상기 커터(6)의 주속도(周速度)가 상기 컨베이어(1)의 이송속도와 동일하게 하는 것이 중요하다. 이는, 회전제어구동부(3)와 회전롤(4)의 각속도비, 그리고 커터(6)의 바깥지름을 고려하면, 쉽게 결정될 수 있다.On the other hand, as shown in FIG. 2 and FIG. 3, the rotation roll driving part 3 is provided in the rotation control drive part 3 via the transmission means like the timing belt 8. As shown in FIG. The cutter 6 is provided at equal intervals around the rotary roll 4. It may be formed integrally or may be joined by general fastening means, such as a bolt and a screw. Accordingly, when the rotation control driving unit 3 rotates, the rotation roll 4 interlocks and rotates. At this time, it is important to make the circumferential speed of the cutter 6 equal to the conveyance speed of the conveyor 1. This can be easily determined in consideration of the angular velocity ratio of the rotation control driving unit 3 and the rotary roll 4 and the outer diameter of the cutter 6.

상기 커터(6)의 바깥지름은 상기 컨베이어(1)와 간섭을 일으키지 않도록 적절히 조정될 필요가 있다.The outer diameter of the cutter 6 needs to be properly adjusted so as not to interfere with the conveyor 1.

그리고, 상기 회전롤(4)은, 별도의 프레임(미도시)에 설치되어 있다.And the said rotary roll 4 is provided in another frame (not shown).

한편, 상기 커터(6)는 회전롤(4)의 둘레방향으로 등간격으로 2개 이상 설치되는 것이 바람직하다. 이에 따라, 커터(6)중 하나의 날(刃)이 타이어 반제품을 절단하고 일정 각도로 회전한 후 곧 바로 멈추고, 다음 절단을 위해 대기하면 되기 때문에, 불필요한 여분의 회전을 피할 수 있게 된다.On the other hand, it is preferable that at least two cutters 6 are installed at equal intervals in the circumferential direction of the rotary roll 4. Thereby, since the blade of one of the cutters 6 cuts the tire semifinished product and rotates at an angle, it stops immediately and waits for the next cutting, thereby avoiding unnecessary extra rotation.

또한, 상기 커터(6)에는 전열선(10)이 연결되어 있어, 가열과 동시에 절단작업이 이루어지기 때문에 절단작업이 보다 원활하게 된다. 상기 전열선(10)은 커터(6)의 뿌리 부분에 설치되어도 되고, 표면에 홈을 형성하고 그 홈 내부에 삽입하여 설치하여도 된다.In addition, since the heating wire 10 is connected to the cutter 6, since the cutting operation is performed at the same time as the heating, the cutting operation becomes smoother. The heating wire 10 may be provided at the root portion of the cutter 6, or may be provided by forming a groove on the surface and inserting it into the groove.

상기한 바와 같은 구성의 본 발명에 따르면, 타이어 반제품을 잡아늘려서 절단하지 않으므로, 변형됨이 없이 매끈하게 일정길이만큼 절단할 수 있다는 이점이 있다.According to the present invention having the configuration as described above, since the tire semi-finished product is not stretched and cut, there is an advantage that can be cut smoothly by a certain length without being deformed.

또한, 커터에 전열선이 연결되어 있어, 타이어 반제품이 보다 원활하게 절단될 수 있다.In addition, the heating wire is connected to the cutter, the tire semi-finished product can be cut more smoothly.
