Description

연동기를 이용한 나선파형관의 제조방법{manufacture method of spiral pipe using interlocking machine} Manufacturing method of spiral wave tube using interlocking machine {manufacture method of spiral pipe using interlocking machine}

본 발명은 산업용으로 사용하는 나선파형관의 제조방법에 관한 것으로, 더욱 상세하게는 합성수지 내에 철판이 매입되고 외면으로는 나선형 구조를 이루게 하여 강도를 향상시킨 나선파형관 성형기의 속도에 연동하여 절곡성형기의 속도를 제어할 수 있게 한 연동기를 이용한 나선파형관의 제조방법에 관한 것이다. The present invention relates to a method for manufacturing a spiral wave tube for use in industry, and more particularly, to the speed of the bending machine in conjunction with the speed of the spiral wave tube forming machine to improve the strength by embedding the steel plate in the synthetic resin and forming a spiral structure on the outer surface It relates to a method for manufacturing a spiral wave tube using a linker that can control the.

일반적으로 나선파형관을 합성수지만으로 제조하는 경우 나선파형관의 인장강도, 충격강도 및 압축강도(땅속에 매설시 미치는 토압 등)에 취약하다고 하는 문제점이 있고, 또 내식성도 약한 문제점이 있다. In general, when the spiral wave tube is manufactured using only synthetic resin, there is a problem that the spiral wave tube is vulnerable to tensile strength, impact strength, and compressive strength (earth pressure when buried in the ground), and also has a weak corrosion resistance.

이러한 문제점을 해결하고자 국내 특허 공개번호 제2009-0023898호(2009년03월06일자 공개)의 "나선파형관의 제조방법 및 그 제조장치"와 국내 특허 등록번호 제10-0906003호(2009년06월26일자 등록)의 "철판 매입 파형 수지관 제조장치 및 그 제조방법"이 제시되어 있다. In order to solve this problem, "Spiral wave tube manufacturing method and apparatus thereof" of Korean Patent Publication No. 2009-0023898 (published on March 06, 2009) and Korean Patent Registration No. 10-0906003 (June 2009) 26 of the registration), "an iron plate embedded corrugated resin tube manufacturing apparatus and its manufacturing method" is presented.

이와 같은 선행기술들은 나선파형관의 내부에 철판이 매입되게 함으로서 나선파형관의 강도를 개선하여 수명을 길게 하는 내구성을 갖게 한 것으로, 그 구성은 철판띠를 U자형 단면으로 절곡하여 코일 형태로 감아주는 절곡성형기와, 상기 절곡성형기의 일측에 설치되어 그 절곡성형기에 의해 형성된 철판을 권회시키면서 철판의 양면에 합성수지를 접착하여 나선파형관을 제조하는 관성형기로 이루어진다. Such prior arts have the durability to lengthen the service life by improving the strength of the spiral wave tube by embedding the iron plate inside the spiral wave tube, the configuration of the bending bent in the coil form by bending the iron plate strip in a U-shaped cross section The molding machine is formed on one side of the bending molding machine and is made of a tubular molding machine for manufacturing a spiral wave tube by bonding a synthetic resin to both sides of the iron plate while winding the iron plate formed by the bending molding machine.

그러나 이러한 선행기술들은 상기 관성형기에서 철판이 매입되게 나선파형관을 제조할 때, 상기 절곡성형기로부터 형성되어 상기 관성형기로 공급되는 철판이 관성형기의 구동 속도와는 상관없이 공급되었기 때문에 나선파형관의 내부에 철판을 균일한 간격을 유지하도록 매입할 수 없었다. 즉, 관성형기의 구동 속도와 절곡성형기의 구동 속도가 서로 다르기 때문에 불량이 발생할 수밖에 없으며, 종래에는 이를 해결할 수 없었다. However, these prior arts, when manufacturing the spiral wave tube so that the iron plate is embedded in the tubular molding machine, since the iron plate formed from the bending molding machine supplied to the tubular molding machine was supplied irrespective of the driving speed of the tubular molding machine, The iron plate could not be purchased so as to maintain a uniform interval. That is, since the driving speed of the inertial molding machine and the driving speed of the bending molding machine are different from each other, a defect may inevitably occur, and this cannot be solved conventionally.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 더욱 상세하게 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도시된 바와 같이, 본 발명에 따른 연동기를 이용한 나선파형관의 제조방법은 철판띠(8)를 U자형의 단면으로 절곡하여 코일 형태로 감아주는 단계를 구비하고 있으며, 이러한 단계는 제2모터(2)로 구동되는 절곡성형기(1)에 의해 이루어진다. As shown, the spiral wave tube manufacturing method using a linkage according to the present invention has a step of winding the iron plate strip 8 to the U-shaped cross section in the form of a coil, the step is a second motor (2) It is made by the bending molding machine (1) is driven by.

도시된 바와 같이, 본 발명에 따른 연동기를 이용한 나선파형관의 제조방법은 코일 형태로 감긴 철판띠(8)의 양면에 합성수지를 접착하여 철판띠가 매입된 나선파형관(9)을 제조하는 단계를 구비하고 있으며, 이러한 단계는 제1모터(4)에 의해 구동되는 관성형기(3)에 의해 이루어진다. As shown, the manufacturing method of the spiral wave tube using the interlocker according to the present invention comprises the step of manufacturing a spiral wave tube (9) in which the iron plate strip is embedded by bonding a synthetic resin on both sides of the coiled iron strip (8). This step is performed by an inertial molding machine 3 driven by the first motor 4.

이때, 상기 관성형기(3)는 절곡성형기(1)의 일측에 설치하여 상기 절곡성형기(1)에서 형성된 철판띠(8)를 상기 관성형기(3)에서 권회시키면서 철판띠(8)의 양면에 합성수지를 접착하여 철판띠가 매입된 나선파형관(9)을 제조하는 것으로, 이러한 관성형기(3)는 선행기술들에 자세하게 도시되어 있다. At this time, the inertial molding machine (3) is installed on one side of the bending molding machine (1) while winding the iron plate (8) formed in the bending molding machine (1) on the both sides of the iron plate belt (8) A spiral wave tube 9 in which an iron plate is embedded by bonding a synthetic resin is manufactured, and such an inertial molding machine 3 is shown in detail in the prior arts.

도시된 바와 같이, 본 발명에 따른 연동기를 이용한 나선파형관의 제조방법은 상기 제2모터(2)의 구동 속도가 상기 제1모터(4)와 동일한 속도로 연동하여 구동될 수 있게 제어하는 속도 연동 제어단계를 구비하고 있으며, 이러한 단계는 본 발명의 가장 큰 특징을 이루는 부분이다. As shown, the method of manufacturing a spiral wave tube using a linkage according to the present invention is a speed interlocking control so that the driving speed of the second motor 2 can be driven in conjunction with the same speed as the first motor (4) A control step is provided, and this step is a part of the biggest feature of the present invention.

이러한 속도 연동 제어단계는 상기 절곡성형기(1)로부터 관성형기(3)로 공급되는 코일 형태로 감긴 철판띠(8)를 자중에 의해 눌러주도록 감지판(5)을 설치하여 상기 철판띠(8)의 높낮이 변화에 따라 상기 감지판(5)이 유동되게 한다. In this speed-linked control step, the sensing plate 5 is installed to press the iron plate 8 wound in the form of a coil supplied from the bending machine 1 to the inertial machine 3 by its own weight, thereby providing the iron plate 8. The sensing plate 5 is allowed to flow in accordance with the change in height.

이때, 상기 철판띠(8)의 높낮이 변화에 대하여 설명하면, 상기 절곡성형기(1)로부터 상기 관성형기(3)로 이동되는 코일 형태로 감긴 철판띠(8)는 상기 관성형기(3)의 제1모터(4)가 상기 절곡성형기(1)의 제2모터(2)보다 빠르게 회전하게 되면 상기 코일 형태로 감긴 철판띠(8)는 관성형기(3)로 당겨지게 되므로 코일 형태의 직경이 작아져 낮아지게 되고, 이와는 반대로 상기 관성형기(3)의 제1모터(4)가 상기 절곡성형기(1)의 제2모터(2)보다 느리게 회전하게 되면 상기 코일 형태로 감긴 철판띠(8)는 관성형기(3)에서 밀리게 되므로 코일 형태의 직경이 커지게 되어 높아지게 된다. In this case, when the height change of the iron plate 8 is described, the iron plate 8 wound in the form of a coil moving from the bending machine 1 to the inertial machine 3 is made of the first of the inertia machine 3. When the motor 4 rotates faster than the second motor 2 of the bending machine 1, the coil strip 8 wound in the coil shape is pulled by the injector 3 so that the diameter of the coil shape is small. On the contrary, when the first motor 4 of the inertial molding machine 3 rotates slower than the second motor 2 of the bending molding machine 1, the iron plate 8 wound in the coil shape is Since it is pushed out of the injector (3), the diameter of the coil form becomes larger and becomes higher.

이와 같은 원리로 상기 철판띠(8)가 높낮이 변화될 때 상기 감지판(5)이 그 변화에 따라 유동되며, 상기 감지판(5)의 유동을 감지할 수 있게 차동트랜스(6)를 설치하여 상기 차동트랜스(6)에서 감지되는 제어값으로 상기 제1모터(4)가 상기 제2모터(2)보다 빨리 회전하는가 늦게 회전되는가를 판단하여 상기 제2모터(2)를 제어하는 전기트랜스(7)를 작동시키는 제어신호로 작용되게 함으로서, 상기 제2모터(2)의 구동 속도를 상기 제1모터(4)와 동일한 속도로 구동되게 연동하여 제어할 수 있다. In the same principle, when the iron plate 8 changes in height, the sensing plate 5 flows according to the change, and the differential transformer 6 is installed to detect the flow of the sensing plate 5. An electric transformer controlling the second motor 2 by determining whether the first motor 4 rotates faster or later than the second motor 2 based on the control value detected by the differential transformer 6. By acting as a control signal for operating 7), the drive speed of the second motor (2) can be driven in conjunction with the first motor (4) to drive in conjunction with the control.

예컨대, 상기 제1모터(4)의 회전 속도가 상기 제2모터(2)의 회전 속도 보다 빠를 경우 코일 형태로 감긴 철판띠(8)는 관성형기(3)로 빨리 이동되기 때문에 코일 형태의 직경이 작아져 상기 감지판(5)은 아래로 내려가고, 이를 차동트랜스(6)의 침(6a)으로 감지하여 제2모터(2)의 회전속도를 빠르게 제어하여 제1모터(4)의 회전속도와 동일하게 제어한다. For example, when the rotational speed of the first motor 4 is faster than the rotational speed of the second motor 2, the coil strip 8 wound in the form of a coil is moved to the inertia 3 so that the diameter of the coil form is increased. Since the sensing plate 5 is lowered, the sensing plate 5 is lowered, and the sensing plate 5 is sensed by the needle 6a of the differential transformer 6 to quickly control the rotation speed of the second motor 2 to rotate the first motor 4. Control same as speed.

또한, 상기 제1모터(4)의 회전 속도가 상기 제2모터(2)의 회전 속도 보다 느릴 경우 코일 형태로 감긴 철판띠(8)는 관성형기(3)로부터 밀리게 되므로 코일 형태의 직경이 커져 상기 감지판(5)은 위로 올라가고, 이를 차동트랜스(6)의 침(6a)으로 감지하여 제2모터(2)의 회전속도를 느리게 제어하여 제1모터(4)의 회전속도와 동일하게 제어한다. In addition, when the rotational speed of the first motor 4 is slower than the rotational speed of the second motor 2, the coil strip 8 wound in the form of a coil is pushed out of the inertial molding machine 3 so that the diameter of the coil form is increased. As the sensor plate 5 is raised, the sensing plate 5 is upwardly sensed by the needle 6a of the differential transformer 6, and the rotation speed of the second motor 2 is controlled to be the same as the rotation speed of the first motor 4. To control.

따라서 이러한 속도 연동 제어단계가 없으면 관성형기(3)와 절곡성형기(1)의 구동 속도가 달라지게 되기 때문에 상기 관성형기(3)에서 나선파형관(9)을 제조할 수 없다. Therefore, without such a speed interlocking control step, since the driving speed of the inertial molding machine 3 and the bending molding machine 1 is different, the spiral wave tube 9 cannot be manufactured in the inertial molding machine 3.

이와 같은 본 발명의 연동기를 이용한 나선파형관의 제조방법은, 먼저 제2모터(2)로 구동되는 절곡성형기(1)에 의해 철판띠(8)를 U자형의 단면으로 절곡하여 코일 형태로 감아주고, 이후 코일 형태로 감긴 철판띠(8)를 제1모터(4)로 구동되는 관성형기(3)에서 권회시키면서 철판띠(8)의 양면에 합성수지를 접착하여 철판띠가 매입된 나선파형관(9)을 제조한다. In the spiral wave tube manufacturing method using the linkage of the present invention, the iron plate 8 is bent into a U-shaped cross section by a bending molding machine 1 driven by the second motor 2 and wound in a coil shape. Then, the spiral wave tube (9) in which the iron strip is embedded by bonding a synthetic resin to both sides of the iron strip (8) while winding the coiled strip (8) wound in a coil shape in the inertial molding machine (3) driven by the first motor (9). ).

이때, 상기 절곡성형기(1)의 제2모터(2)가 상기 관성형기(3)의 제1모터(4)와 동일한 속도로 회전하기 않으면 나선파형관(9)을 제조할 수 없기 때문에 본 발명의 속도 연동 제어단계에 의해 상기 제2모터(2)가 제1모터(4)와 동일한 속도로 구동될 수 있게 한다. 즉, 상기 관성형기(3)와 절곡성형기(1)의 사이에 감지판(5)과 차동트랜스(6)를 설치하여 상기 제2모터(2)의 구동속도를 상기 제1모터(4)와 동일한 속도로 연동하여 구동되게 제어할 수 있다. In this case, the spiral wave tube 9 cannot be manufactured unless the second motor 2 of the bending molding machine 1 rotates at the same speed as the first motor 4 of the inertial molding machine 3. The second motor 2 may be driven at the same speed as the first motor 4 by the speed interlocking control step. That is, the sensing plate 5 and the differential transformer 6 are installed between the inertial molding machine 3 and the bending molding machine 1 to drive the driving speed of the second motor 2 to the first motor 4. It can be controlled to be driven in conjunction with the same speed.

이러한 속도 연동 제어단계는, 상기 절곡성형기(1)로부터 관성형기(3)로 공급되는 코일 형태로 감긴 철판띠(8)를 자중에 의해 눌러주도록 감지판(5)을 설치하여 상기 감지판(5)이 철판띠의 높낮이 변화에 따라 유동되게 하고, 상기 감지판(5)의 유동을 감지할 수 있게 차동트랜스(6)를 설치하여 상기 차동트랜스(6)에서 감지되는 제어값으로 상기 제1모터(4)가 상기 제2모터(2)보다 빨리 회전하는가 늦게 회전되는가를 판단하여 상기 제2모터(2)를 제어하는 전기트랜스(7)를 작동시키는 제어신호로 작용되게 함으로서, 상기 제2모터(2)의 구동 속도를 상기 제1모터(4)와 동일한 속도로 연동하여 구동되게 제어한다.
