After that, the core fibers 10a and 10b of the plurality of strands pass through the first guide 29a, and the core fibers 10a and 10b of the plurality of strands are gathered into the core fiber 10 of one strand, and at the same time, excessively The impregnated first resin 25 is removed from the core fiber 10. As the first resin 20, epoxy resin or phenol resin or urethane resin or unsaturated polyester or polyester resin or polyamide or vinyl ester resin is used.
코어섬유(10)는 다음 설비인 브레이딩 장치(30)로 진입한다. 브레이딩 장치(30)는 코어섬유(10)가 관통하는 원형 프레임과, 그 프레임에 설치되며 각각 정해진 이동로를 따라 이동하며 피복섬유(13a, 13b)가 감겨진 다수 개의 타래(34)를 포함하며, 피복섬유(13a, 13b)는 각각의 타래(34)로부터 인출되어 코어섬유(10)의 둘레로 전진하여 위치하게 된다. 피복섬유(13a, 13b) 또한 코어섬유(10)와 같이 탄소섬유 또는 유리섬유 또는 아라미드섬유 또는 폴리에틸렌 또는 나일론 등이 이용되며 이런 피복섬유(13a, 13b)의 다수 가닥이 토우 또는 로우빙 또는 밧줄 형태로 꼬거나 꼬지 않은 섬유형태로 공급된다. 그러면, 코어섬유(10)에 함침된 제 1 수지(25)는 피복섬유(13) 쪽으로 함침되면서 코어섬유(10)와 피복섬유(13)를 함께 함침하고 있는 상태가 된다.The core fiber 10 enters the next facility, the braiding device 30. The braiding device 30 includes a circular frame through which the core fiber 10 passes, and a plurality of skeins 34 which are installed on the frame and each move along a predetermined movement path and are wound with the covering fibers 13a and 13b. And, the coated fibers (13a, 13b) are withdrawn from each of the skein 34 and is positioned to advance around the core fiber (10). The coated fibers 13a, 13b are also carbon fiber, glass fiber, aramid fiber, polyethylene or nylon, like the core fiber 10, and a plurality of strands of such coated fibers 13a, 13b are in the form of tow or lobbing or rope. It is supplied in the form of twisted or untwisted fibers. Then, the first resin 25 impregnated in the core fiber 10 is impregnated toward the coated fiber 13 and the core fiber 10 and the coated fiber 13 are impregnated together.
이렇게 형성된 코어섬유(10)와 피복섬유(13)는 제품의 종류 및 수지의 필요한 양에 따라 제 2 수지조(21)를 통과하여 코어섬유(10)와 피복섬유(13)에 제 2 수지(26)를 함침시킨다. 코어섬유(10)와 피복섬유(13)는 제 2 수지(26)를 함침한 후에 제 2 가이드(29b)를 통과하여 일정량 이상의 제 2 수지(26)를 제거하고, 가열장 치(40)로 진입하여 열을 받게된다. 이 때, 가열장치(40)는 선단가열부(40a)와 후단가열부 (40b)의 2단 가열형태를 가지며, 선단가열부(40a)와 후단가열부(40b)의 사이에 압축롤러(60)가 위치한다. 선단가열부(40a)를 통과한 섬유는 불완전하게 경화된 상태로 압축롤러(60)를 통과하게 된다.The core fiber 10 and the coated fiber 13 formed in this way pass through the second resin tank 21 according to the type of product and the required amount of resin, and are then added to the core fiber 10 and the coated fiber 13. 26) is impregnated. After the core fiber 10 and the coated fiber 13 are impregnated with the second resin 26, they pass through the second guide 29b to remove the second resin 26 or more, and then use the heating device 40. It enters and is heated. At this time, the heating device 40 has a two-stage heating type of the front heating portion 40a and the rear heating portion 40b, and a compression roller 60 between the front heating portion 40a and the rear heating portion 40b. ) Is located. The fibers passing through the tip heating portion 40a pass through the compression roller 60 in an incompletely cured state.
도 4는 종래 기술에 따른 섬유 보강근 제조 장치가 구비하는 압축 롤러를 도시한 도면이다. 압축롤러(60)는 진행하는 섬유의 상하에 설치되며, 홈(63)이 상하부 압축롤러(61, 62)의 원주를 따라 일정한 간격으로 형성된다.4 is a view showing a compression roller provided in the apparatus for manufacturing fiber reinforcement bars according to the prior art. The compression roller 60 is installed above and below the advancing fiber, and grooves 63 are formed at regular intervals along the circumference of the upper and lower compression rollers 61 and 62.
이런 홈(63)이 형성된 상하부 압축롤러(61, 62)의 사이에 코어섬유(10)와 피복섬유(13)가 압착되면서, 불완전하게 경화된 피복섬유(13)의 외부에는 압착롤러(61, 62)의 홈(63)에 대응하는 돌출부가 형성된다. 돌출부가 형성된 섬유는 가열장치(40)의 후단가열장치(40b)를 통과하면서 완전히 경화되어 섬유 보강근(17)이 형성되며, 이렇게 형성된 섬유 보강근(17)은 냉각장치(50)를 통과하면서 상온으로 된다.While the core fiber 10 and the coated fiber 13 are compressed between the upper and lower compression rollers 61 and 62 in which the groove 63 is formed, the outside of the incompletely cured coated fiber 13 is a pressing roller 61, A protrusion corresponding to the groove 63 of 62) is formed. The fiber with the protrusion is completely hardened while passing through the rear heating device 40b of the heating device 40 to form the fiber reinforcement bar 17, and the fiber reinforcement bar 17 thus formed passes through the cooling device 50 to room temperature. do.
그러나, 종래 기술에서는, 섬유보강근은 가열 장치(40)가 외부에서 열을 가하여 경화시킴으로써, 내부에 위치한 섬유에 함침된 수지까지 완벽히 경화하는 데 시간이 오래 걸린다는 단점이 있었다.However, in the prior art, the fiber reinforcement reinforcement has a disadvantage in that it takes a long time to completely cure the resin impregnated into the fibers located inside by curing the heating device 40 by applying heat from the outside.
유리 섬유를 이용하여 유리 섬유 리바 등을 제조할 때, 원사를 다수 꼬아서 제조한다. 이때, 원사의 길이에는 한계가 있어, 원사를 서로 겹쳐 본딩함으로써 원사를 길게 이을 수 있다.When manufacturing a glass fiber riva or the like using glass fiber, it is manufactured by twisting a number of yarns. At this time, there is a limit to the length of the yarns, and the yarns can be lengthened by overlapping and bonding the yarns to each other.
종래에는 유리 섬유 원사의 접합 시에 도 5와 같이, 제1 원사(1)의 단부와 제2 원사(2)의 단부를 서로 겹치게 한 다음, 수작업으로 본딩 작업을 하였다.In the related art, as shown in FIG. 5, when the glass fiber yarn is bonded, the end of the first yarn 1 and the end of the second yarn 2 are overlapped with each other, and then the bonding operation is performed manually.
도 6에는 종래 기술에 따른 유리섬유 리바 제조 장치의 개략적인 구성도를 도시한 도면이다. 섬유 권취릴(11), 수지 공급부(12), 성형노즐(13), 회전 권취기(14), 블레이딩 장치(15), 가열기(16) 및 인발기(17)를 포함하고 있되, 추가적으로 심재가 통과할 때 피치부(22)의 주변에서 피복섬유(23)를 심재(21)의 표면과 피치부(22) 방향으로 가압해주는 가압장치(30)를 블레이딩 장치(15)와 가열기(16) 사이에 구비하고 있다.6 is a view showing a schematic configuration of a glass fiber rebar manufacturing apparatus according to the prior art. It includes a fiber winding reel 11, a resin supply unit 12, a molding nozzle 13, a rotary winder 14, a blading device 15, a heater 16 and a drawer 17, but additionally a core material When passing through, a pressurizing device 30 that presses the coated fiber 23 in the direction of the pitch part 22 and the surface of the core material 21 around the pitch part 22 is applied to the blading device 15 and the heater 16 ) Between.
도 7은 종래 기술에 따른 유리 섬유 리바를 인발하는 인발기를 도시한 도면이다. 이때, 인발기(17)는 우레탄 A90 재질로 주로 제조되며, 유리 섬유 리바(1)를 상하에서 가압한 상태에서 인발하게 되는데, 인발기(17)의 표면이 매끈하고 마찰계수가 낮아 유리 섬유 리바(1)가 인발기(17)에 대해 미끄러지면서 마모되는 단점이 있었다.7 is a view showing a drawing machine for drawing a glass fiber rebar according to the prior art. At this time, the drawer 17 is mainly made of urethane A90 material, and is pulled out while the glass fiber rebar 1 is pressed up and down, and the surface of the drawer 17 is smooth and the friction coefficient is low. (1) There was a drawback of being worn while sliding against the drawer (17).
도 8은 종래 기술에 따른 유리 섬유 리바 제조 장치가 구비하는 회전 권취기를 대략적으로 도시한 도면이다. 회전 권취기 장치의 중앙으로는 심재(21)가 이동하며, 회전 권취 릴(24)에 미리 감아둔 유리 섬유(20)를 회전시키며 심재(21) 주위에 감아 피치부(22)를 형성한다. 8 is a view schematically showing a rotary winder provided in the apparatus for manufacturing a glass fiber rebar according to the prior art. The core material 21 is moved to the center of the rotary take-up device, and the glass fiber 20 previously wound on the rotary take-up reel 24 is rotated and wound around the core material 21 to form a pitch portion 22.
이때, 피치부(22)를 이루는 유리 섬유들은 강성을 위해서, 피치부(22)가 심재(21) 주위를 감고 있는 형태이면서, 피치부(22) 자체도 트위스트되어 있어야 한다. At this time, the glass fibers constituting the pitch portion 22 are in a form in which the pitch portion 22 is wound around the core material 21 for rigidity, and the pitch portion 22 itself must also be twisted.
그러나 종래 기술에 따른 리바의 제조 장치는, 피치부(22)를 단순히 심재(21) 주위에 감는 역할만을 하고 있어 피치부(22)를 형성하기 위한 피치 섬유를 미리 코일링한 다음에 회전 권취릴(24)에 감아놓아야 했다. However, the manufacturing apparatus of the rebar according to the prior art only plays a role of winding the pitch portion 22 around the core material 21, so that the pitch fibers for forming the pitch portion 22 are pre-coiled and then a rotary winding reel It had to be wrapped in (24).
도 9는 종래 기술에 따른 보강근의 커팅 장치를 도시한 도면이다. 9 is a view showing a cutting device for reinforcing bars according to the prior art.
종래 기술에 따른 커팅 장치(15)는 보강근(20)을 고정하기 위한 클램프(42)와 컷팅 블레이드(44)를 구비한다. 이때, 보강근(20)은 인발기(17)에서 계속해서 인발되어 나오면서 컷팅이 진행된다. 컷팅 블레이드(44)는 상, 하 방향으로 이동하며 컷팅을 진행할 때, 보강근(20)이 계속하여 전방으로 진행함으로써, 컷팅면이 비스듬하게 형성된다. 또한, 컷팅 블레이드(44)가 인발되어 나온 보강근(20)을 가압할 때, 보강근(20)의 상, 하 위치를 고정하기 위한 클램프(42)를 구비한다 하더라도, 일측만이 고정되어 있어 블레이드(44)가 가압할 경우 자유단이 상, 하로 흔들리며 컷팅면이 고르지 않게 절단된다는 단점이 있었다. The cutting device 15 according to the prior art includes a clamp 42 and a cutting blade 44 for fixing the reinforcing bar 20. At this time, the reinforcing bar 20 is continuously drawn out from the drawer 17 and cutting is performed. The cutting blade 44 moves upward and downward, and when cutting proceeds, the reinforcing bar 20 continues to advance forward, so that the cutting surface is formed obliquely. In addition, when the cutting blade 44 is pulled out and presses the reinforcing bar 20, even if a clamp 42 for fixing the upper and lower positions of the reinforcing bar 20 is provided, only one side is fixed and the blade ( 44) has the disadvantage that the free end is shaken up and down and the cutting surface is cut unevenly.

The compression molding and heating device of the apparatus for manufacturing a glass fiber reinforcement bar according to an embodiment of the present invention includes a pair of rails 100 extending in the same direction as the moving direction of the glass fiber reinforcement bar 1000. A pair of clamps 200 are installed so as to be movable forward and backward along the rail 100. A pair of clamps 200 are provided with molds 300a and 300b for compression-molding the glass fiber reinforcing bars 1000, respectively. In the clamp 200, the distance between the molds 300a and 300b is adjusted, such as the cylinder 210, so that the molds 300a and 300b clamp and unclamp the glass fiber reinforcing bar 1000.
금형(300a, 300b)은 가열된 상태를 유지하며, 수지가 함침된 유리섬유 보강근(1000)을 압착하여 성형하는 동시에 가열하여 건조시킬 수 있다. 이때, 금형(300a, 300b)은 유리섬유 보강근(1000)을 클램핑하여 성형과 동시에 가열하면서, 레일(100)을 따라 유리섬유 보강근(1000)이 인발되는 방향으로 이동하면서 성형 및 가열 건조를 동시에 수행할 수 있다. 압착 성형 시에 유리섬유 보강근(1000) 내에 과다하게 함침된 수지가 빠져나오며 금형에 의해 가열 건조된다. 이때, 금형금형(300a, 300b)의 가열 온도는 약 80℃ 내외를 유지하여, 유리섬유 보강근(1000)에 돌출된 피치(1100; 도 10 참조)를 성형한다.

성형을 끝내고, 인발기를 통해 인발되는 유리 섬유 리바는 본 발명의 유리 섬유 리바용 컷팅 장치에서 원하는 길이로 컷팅된다. After the molding is finished, the glass fiber rebar drawn through the drawing machine is cut to a desired length in the cutting apparatus for glass fiber rebar of the present invention.
본 발명에 따른 유리 섬유 리바용 컷팅 장치는, 고정 프레임(500, 510, 520)을 따라 이동가능하게 설치된 무빙 프레임(100)에 클램핑 어셈블리와 블레이드 어셈블리가 설치된다. In the cutting device for glass fiber rebar according to the present invention, a clamping assembly and a blade assembly are installed in a moving frame 100 installed to be movable along a fixed frame 500, 510, 520.
블레이드 어셈블리는, 회전력을 제공하는 모터(210)와, 모터(210)를 승하강시키기 위한 실린더(200), 실린더(200)에 의해 승하강할 때 모터(210)를 지지하는 슬라이딩 가이더(202)를 구비한다. 모터(210)에 바로 블레이드(240)가 설치되어 유리 섬유 리바(20)를 컷팅할 수도 있으나, 본 발명은, 벨트(220)를 이용해 종동부(230)와 연결하고, 종동부(230)에 블레이드(240)를 설치하였다. 상대적으로 크기가 큰 모터(210)를 상부에 배치하고, 크기가 작은 종동부(230)를 유리 섬유 리바(20) 근처에 배치함으로써, 클램핑 어셈블리와 블레이드(240) 사이의 거리를 좁힐 수 있어서, 유리 섬유 리바(20)를 더 단단히 고정할 수 있다. The blade assembly includes a motor 210 that provides rotational force, a cylinder 200 for raising and lowering the motor 210, and a sliding guide 202 that supports the motor 210 when it is raised and lowered by the cylinder 200. Equipped. The blade 240 is installed directly on the motor 210 to cut the glass fiber rebar 20, but in the present invention, the belt 220 is used to connect the follower 230 and the follower 230 The blade 240 was installed. By arranging the relatively large motor 210 at the top and placing the small sized follower 230 near the glass fiber rebar 20, the distance between the clamping assembly and the blade 240 can be shortened, The glass fiber rebar 20 can be fixed more firmly.
무빙 프레임(100)에는 유리 섬유 리바(20)를 클램핑 하는 클램핑 어셈블리가 한 쌍 설치된다. 각 클램핑 어셈블리는 무빙 프레임(100)에 고정되는 클램핑 프레임(300, 400), 각 클램핑 프레임(300, 400)에 설치되는 각 한 쌍의 실린더(310, 320, 410, 420), 각 실린더(310, 320, 410, 420)에 각각 연결되어 유리 섬유 리바(20)를 클램핑 하는 클램프 부(320, 420)를 구비한다. 블레이드(240)의 전방과 후방에 모두 클램핑 어셈블리가 배치되기 때문에, 리바(20)가 커팅 과정에서 상, 하로 진동하는 것을 더욱 확실히 방지할 수 있다는 장점이 있다. A pair of clamping assemblies clamping the glass fiber rebar 20 is installed on the moving frame 100. Each clamping assembly includes clamping frames 300 and 400 fixed to the moving frame 100, a pair of cylinders 310, 320, 410 and 420 installed on each clamping frame 300 and 400, and each cylinder 310 , 320, 410, and 420 are connected to each of the clamp portions 320 and 420 for clamping the glass fiber rebar 20. Since the clamping assembly is disposed at both the front and the rear of the blade 240, there is an advantage that it is possible to more reliably prevent the rebar 20 from vibrating up and down during the cutting process.
본 발명에 따른 유리 섬유 리바용 컷팅 장치의 컷팅 방법은 다음과 같다. 먼저 유리 섬유 리바(20)가 원하는 길이만큼 인발되면, 클램핑 어셈블리가 유리 섬유 리바(20)를 클램핑한다. 이후 블레이드 어셈블리의 실린더(200)가 작동하며, 모터(210), 벨트(220), 종동부(230) 및 블레이드(240)가 모두 함께 하강하게 된다. 이후, 블레이드(240)가 유리 섬유 리바(20)에 닿아 컷팅을 시작하면 무빙 프레임(100)이 리바(20)의 인발 속도와 동일한 속도로 이동한다. 따라서, 블레이드(240)는 리바(20)에 대해 상하방향으로만 상대 이동을 하며, 전, 후 방향으로는 상대 속도가 0이 되어 절단면이 수직하게 형성된다. 무빙 프레임(100)의 이동은 꼭 블레이드(240)가 리바(20)에 닿은 뒤에 이루어질 필요는 없으며, 블레이드 어셈블리의 실린더(200)가 작동을 시작할 때, 혹은 클램핑 어셈블리의 실린더(310, 320, 410, 420)가 작동을 시작할 때부터 무빙 프레임(100)이 이동을 시작할 수 있다. 블레이드(240)가 리바(20)를 컷팅하는 동안 무빙 프레임(100)이 리바(20)와 같은 속도로 이동중이기만 하면, 무빙 프레임(100)의 무빙 시점은 언제가 되어도 무방하다. 또한, 컷팅이 완료되고 나면, 무빙 프레임(100)은 다시 원위치로 복귀한다. The cutting method of the cutting device for glass fiber rebar according to the present invention is as follows. First, when the glass fiber rebar 20 is drawn to a desired length, the clamping assembly clamps the glass fiber rebar 20. After that, the cylinder 200 of the blade assembly operates, and the motor 210, the belt 220, the follower 230 and the blade 240 all descend together. Thereafter, when the blade 240 touches the glass fiber rebar 20 and starts cutting, the moving frame 100 moves at the same speed as the pulling speed of the rebar 20. Accordingly, the blade 240 moves relative to the rebar 20 only in the vertical direction, and the relative speed becomes 0 in the front and rear directions, so that the cut surface is formed vertically. Movement of the moving frame 100 does not necessarily need to be made after the blade 240 contacts the rebar 20, and when the cylinder 200 of the blade assembly starts to operate, or the cylinders 310, 320, 410 of the clamping assembly The moving frame 100 may start moving from when 420 starts to operate. As long as the moving frame 100 is moving at the same speed as the rebar 20 while the blade 240 is cutting the rebar 20, the moving time of the moving frame 100 may be any time. In addition, after the cutting is completed, the moving frame 100 returns to its original position again.
