도1(a) 및 도1(b)은 본 발명에 따른 폴리우레탄 장갑을 제조하기 위한 폴리우레탄 시트의 제조과정을 설명하기 위한 도면으로, 이를 참고하면 도1(a)에 도시된 바와 같이 공급롤(111)에서 공급된 종이시트지(110)는 한쌍의 이송롤러(112)에 의해 이송되며, 이송되는 과정에서 나이프(113)에 의해 대략 0.04mm 두께로 폴리우레탄 코팅액이 종이시트지 상에 도포된다. 이 후 건조기(114)에서 대략 130도 온도로 3분 내지 5분 정도 건조된 후 권취롤(115)에 권취된 후 40도 내지 70도 온도에서 대략 12시간 내지 14시간 숙성되어 종이시트지 위에 폴리우레탄 시트가 형성되게 된다. 이 후, 도1(b)에 도시된 바와 같이 종이시트지(110)상에서 폴리우레탄 시트(10)를 분리한 후 대략 40cm 내지 60cm의 폭으로 절단한 후 이를 두겹이 되도록 접은 다음 공급롤(11)에 권취하여 본 발명에 따른 폴리우레탄 장갑의 제조장치에 투입되게 된다.Figure 1 (a) and Figure 1 (b) is a view for explaining the manufacturing process of the polyurethane sheet for producing a polyurethane glove according to the present invention, with reference to this supply as shown in Figure 1 (a) The paper sheet paper 110 supplied from the roll 111 is conveyed by a pair of feed rollers 112, and a polyurethane coating liquid is applied onto the paper sheet paper by a knife 113 at a thickness of about 0.04 mm by the knife 113 during the conveying process. . Thereafter, the dryer 114 was dried at a temperature of about 130 degrees for about 3 minutes to about 5 minutes, and then wound up on the take-up roll 115 and aged at about 40 hours to about 70 degrees for about 12 hours to 14 hours. The sheet is to be formed. Thereafter, as shown in FIG. 1 (b), the polyurethane sheet 10 is separated from the paper sheet 110 and then cut into a width of about 40 cm to 60 cm, and then folded to double the feed roll 11. To be wound into the polyurethane glove according to the present invention is put into the apparatus.

도2에는 본 발명에 따른 폴리우레탄 장갑의 제조장치가 개략적으로 도시되어 있는 데, 이를 참고하면 본 발명에 따른 폴리우레탄 장갑의 제조장치는 폴리우레탄 시트 공급롤(11), 한쌍의 이송롤러(12), 가이드롤러(13), 초음파진동기(14), 성형롤러(15) 및 커팅기(16)를 포함한다.Figure 2 schematically shows a manufacturing apparatus of a polyurethane glove according to the present invention, referring to the manufacturing apparatus of the polyurethane glove according to the present invention is a polyurethane sheet supply roll 11, a pair of feed roller 12 ), A guide roller 13, an ultrasonic vibrator 14, a forming roller 15 and a cutting machine (16).

상기 폴리우레탄 시트 공급롤(11)은 전술한 바와 같이 두겹으로 졉혀진 폴리우레탄 시트가 권취된 롤로서 폴리우레탄 시트(10)를 본 발명에 따른 폴리우레탄 장갑의 제조장치에 투입하게 된다.As described above, the polyurethane sheet supply roll 11 is a roll of a polyurethane sheet rolled up in two layers, and the polyurethane sheet 10 is introduced into the apparatus for producing a polyurethane glove according to the present invention.

상기 한쌍의 이송롤러(12)는 폴리우테탄 시트 공급롤(11)에 의해 공급된 폴리우레탄 시트(10)를 전진 이송시키는 역할을 수행하며, 서로 역방향으로 회전하도록 구성되어 있으며, 도시된 바와 같이 초음파진동기(14)와 커팅기(16) 사이에 배치되어 있다.The pair of feed rollers 12 serves to forward feed the polyurethane sheet 10 supplied by the polyurethane sheet feed roll 11, and is configured to rotate in opposite directions to each other, as shown. It is arranged between the ultrasonic vibrator 14 and the cutting machine 16.

상기 가이드롤러(13)는 이송롤러(12)에 의해 이송되는 폴리우레탄 시트의 이송을 안내하는 롤러로서 도시된 것에 한정하지 않고 다양한 위치에 그 수를 증감하여 배치할 수 있음은 당연하다. 또한, 선택적으로 가이드롤러의 일부를 승하강 가능하게 구성하여 이송되는 폴리우테탄 시트에 대해 텐션력을 부여할 수 있음 역시 당연하다.The guide roller 13 is not limited to that shown as a roller for guiding the conveyance of the polyurethane sheet conveyed by the feed roller 12, it is natural that the number can be increased or decreased in various positions. In addition, it is also natural that a part of the guide roller can be selectively lifted to give a tension force to the conveyed polyurethane sheet.

상기 초음파진동기(14)는 초음파로 인해 미세하게 진동하는 공지된 장치를 이용하며, 특히 본 발명에서는 후술할 성형롤러(15)의 가압날(15-1)이 가압하면 가압부분에서 마찰이 발생하여 마찰열을 발생하게 된다. 즉, 초음파진동기의 상면 전체가 항상 열을 발생하는 것이 아니라 성형롤러의 가압날(15-1)과 접촉하는 부분에서만 가압에 의해 마찰열을 발생하는 것이다.The ultrasonic vibrator 14 uses a known device that vibrates finely due to ultrasonic waves, and in particular, in the present invention, when the pressing blade 15-1 of the forming roller 15 to be described below is pressed, friction occurs in the pressing portion. It generates frictional heat. That is, the entire upper surface of the ultrasonic vibrator does not always generate heat, but generates frictional heat by pressurization only at the portion in contact with the pressing blade 15-1 of the forming roller.

상기 성형롤러(15)는 구체적으로 도3에 도시된 바와 같이 외주연에 장갑형상의 가압날(15-1)이 돌출형성되어 있다. 상기 가압날(15-1)은 끝단이 라운드지게 형성되는 것이 바람직하다. 상기 가압날(15-1)은 성형롤러(15)의 외주연에 거쳐 하나의 장갑형상으로 돌출되어 있다. 따라서, 성형롤러의 1회전마다 그 하단으로 이송되는 폴리우레탄 시트상에는 상기 가압날에 대응되는 장갑형상이 하나씩 찍히게 될 것이며, 필요에 따라서는 성형롤러의 직경을 증가시키면 다수의 장갑형상의 가압날을 연속적으로 형성할 수 있을 것이다. 또한, 상기 성형롤러의 가압날(15-1)은 초음파진동기 상면에 연접되게 회동하여 소정의 압력으로 초음파진동기의 상면을 가압하게 된다. 여기서, 상기 성형롤러의 회전은 독립적으로 수행될 수 있지만, 바람직하게는 도시된 바와 같이 상부 이송롤러와 벨트나 체인으로 연결되어 이송롤러의 구동에 연동하여 회전되는 것이 바람직하다.Specifically, as shown in FIG. 3, the forming roller 15 has a glove-shaped pressure blade 15-1 protruding from the outer circumference. The pressing blade 15-1 is preferably formed so that the end is rounded. The pressing blade 15-1 protrudes into a glove shape through the outer circumference of the forming roller 15. Therefore, the glove shape corresponding to the pressing blade will be stamped one by one on the polyurethane sheet conveyed to the lower end of each rotation of the forming roller. It may be formed continuously. In addition, the press blade 15-1 of the forming roller is rotated in contact with the upper surface of the ultrasonic vibrator to press the upper surface of the ultrasonic vibrator at a predetermined pressure. Here, the forming roller may be rotated independently, but it is preferable to be connected to the upper feed roller and the belt or chain as shown in the figure to rotate in conjunction with the driving of the feed roller.

상기 커팅기(16)는 이송롤러(12)의 후방에 마련되어 이송되는 폴리우레탄 시트(10)를 소정간격으로 절단하게 된다. 예시적이지만, 구체적으로 상기 커팅기는 하부커팅기(16-1)와, 상기 하부커팅기에 대해 교차되게 승하가능하는 상부커팅기(16-2)로 구성되어 폴리우테탄 시트를 장갑형성단위별로 절단하게 된다.The cutter 16 cuts the polyurethane sheet 10 provided at the rear of the feed roller 12 at a predetermined interval. Exemplarily, but specifically, the cutting machine is composed of a lower cutter 16-1 and an upper cutter 16-2 that can be lifted to cross the lower cutter, thereby cutting the polyurethane sheet by armor forming unit. .

이와 같이 구성된 본 발명에 따른 폴리우레탄 장갑의 제조장치를 이용하여 폴리우레탄 장갑을 제조하는 방법을 설명한다.It will be described a method for producing a polyurethane glove using the apparatus for producing a polyurethane glove according to the present invention configured as described above.

먼저, 두겹으로 접혀진 폴리우레탄 시트(10)를 폴리우레탄 시트 공급롤(11)을 통해 공급한다. 공급된 폴리우레탄 시트(11)는 다수의 가이드롤러(13) 및 서로 역방향으로 회전하는 한쌍의 이송롤러(12)에 의해 이송안내되다가 초음파진동기(14)와 성형롤러(15) 사이를 통과하게 된다. 이 때, 이송롤러(12)와 연동하여 회전하는 성형롤러의 가압날(15-1)이 초음파진동기(14) 상면에 연접 회동하면 가압날(15-1)은 폴리우레탄 시트(10)를 초음파진동기(14) 상면으로 가압하게 되는 데, 여기서 가압날(15-1)과 초음파진동기(14) 상면의 마찰열로 인해 폴리우레탄 시트는 장갑형상으로 절단됨과 동시에 두겹으로 접혀져 있는 상측 시트과 하측시트의 절단단부가 서로 열융착되어, 도4에 도시된 바와 같이 이송되는 폴리우레탄 시트(10)에는 장갑형상으로 절취 및 열융착된 장갑이 형성되게 된다.First, the polyurethane sheet 10 folded in two layers is supplied through the polyurethane sheet supply roll 11. The supplied polyurethane sheet 11 is guided by a plurality of guide rollers 13 and a pair of feed rollers 12 rotating in opposite directions, and then passes between the ultrasonic vibrator 14 and the forming roller 15. . At this time, when the pressing blade 15-1 of the forming roller rotating in conjunction with the feed roller 12 is rotated in contact with the upper surface of the ultrasonic vibrator 14, the pressing blade 15-1 ultrasonics the polyurethane sheet 10. The upper surface of the vibrator 14 is pressurized, whereby the frictional heat on the upper surface of the presser blade 15-1 and the ultrasonic vibrator 14 cuts the polyurethane sheet into a glove shape and simultaneously cuts the upper sheet and the lower sheet folded in two layers. Ends are thermally fused to each other, the gloves are cut and heat-sealed gloves are formed in the polyurethane sheet 10 is conveyed as shown in FIG.

이후에는 폴리우레탄 시트(10)가 커팅기(16)를 통과할 때 상부커팅기(16-2)가 하강하여 도5에 도시된 바와 같이 폴리우레탄 시트(10)를 장갑형성단위별로 소정간격 절단하면 도6에 도시된 바와 같이 폴리우레탄 시트에서 폴리우레탄 장갑(G) 을 분리하여 수거하면 본 발명이 얻고자 하는 폴리우레탄 장갑(G)을 제공하게 된다.Thereafter, when the polyurethane sheet 10 passes through the cutting machine 16, the upper cutting machine 16-2 is lowered to cut the polyurethane sheet 10 by a predetermined interval as shown in FIG. As shown in 6, separating and collecting the polyurethane glove G from the polyurethane sheet provides the polyurethane glove G desired by the present invention.

이상에서 설명한 바와 같이, 본 발명에 따른 제조장치 및 제조방법에 따르면 폴리우레탄 시트로부터 폴리우레탄 장갑을 제조하기 때문에 제조공정이 간단하며, 그 두께가 극히 얇아 통기성과 신축성이 양호할 뿐만 아니라 우수한 민감성과 접지성을 확보할 수 있는 폴리우레탄 장갑을 제공할 수 있다. 또한, 본 발명에 따르면 연속 회전하는 성형롤러에 의해 폴리우레탄 장갑이 제공되므로, 스텝이송되는 시트상에 프레스가 간헐적으로 프레스하여 성형하여 기존 비닐장갑의 제조방법과는 달리, 제조시간이 단축되므로 대량생산이 가능하여 제조단가를 절감할 수 있다는 잇점이 있다.As described above, according to the manufacturing apparatus and the manufacturing method according to the present invention, because the polyurethane gloves are manufactured from the polyurethane sheet, the manufacturing process is simple, the thickness thereof is extremely thin, the breathability and elasticity is not only good, but also excellent sensitivity and It is possible to provide a polyurethane glove that can secure grounding properties. In addition, according to the present invention, since polyurethane gloves are provided by a continuously rotating molding roller, the press is intermittently press-molded on the step-feeding sheet so that the manufacturing time is shortened, unlike the manufacturing method of conventional vinyl gloves. The advantage is that the production cost can be reduced as production is possible.

한편, 도7에는 본 발명의 보다 바람직한 폴리우레탄 장갑의 제조장치가 개략적으로 도시되어 있는 데, 이를 참고하면 본 실시예는 이송되는 폴리우레탄 시트의 하단으로 종이시트지(20)가 동시에 이송되도록 종이시트지 공급롤(21)을 더 포함하는 데, 이는 폴리우레탄 시트(10)만이 이송되는 경우에는 가이드롤러(13)의 텐션력에 의해 신축성이 좋은 폴리우레탄 시트(10)가 신장되거나 성형롤러(15)의 회전장력에 의해 폴리우레탄 시트(10)가 신장될 수 있는 데, 신장된 상태에서 폴리우레탄 장갑이 분리 및 열융착된 후 다시 수축되면 폴리우레탄 장갑의 사이즈에 변화가 생기는 문제점이 발생할 수 있기 때문에 본 실시예는 신축되지 않는 종이시트지(20) 가 폴리우레탄시트(10)의 하단에 동시에 이송되게 함으로써 폴리우레탄 시트가 신장되는 것을 방지할 수 있기 때문이다.On the other hand, Figure 7 schematically shows a manufacturing apparatus of a more preferred polyurethane gloves of the present invention, with reference to this embodiment is a paper sheet so that the paper sheet 20 is simultaneously transported to the bottom of the polyurethane sheet to be transported It further comprises a feed roll 21, which is a stretchable polyurethane sheet 10 by the tension force of the guide roller 13, when only the polyurethane sheet 10 is conveyed or stretched roller 15 Polyurethane sheet 10 may be stretched by the rotational tension of the polyurethane sheet 10, but when the polyurethane gloves are separated and heat-sealed and then contracted again in the stretched state, a problem may occur in the size of the polyurethane gloves. The present embodiment can prevent the polyurethane sheet from being stretched by allowing the unstretched paper sheet 20 to be simultaneously transported to the lower end of the polyurethane sheet 10. Because.

이상에서 설명한 바와 같이, 본 발명에 따르면 폴리우레탄 시트으로터 폴리우레탄 장갑을 제조하기 때문에 제조공정이 간단하며 특히 양호한 통기성과 신축성, 우수한 민감성과 접지성을 확보할 수 있는 폴리우레탄 장갑을 제공할 수 있다는 잇점이 있다. 또한, 프레스 방식이 아닌 연속 회전하는 성형롤러에 의해 폴리우레탄 장갑이 제공되므로 제조시간이 단축되어 제조단가를 절감할 수 있다는 효과가 있다. 나아가, 폴리우레탄 시트지 하단에 비신축성 종이시트지가 동시에 이송되므로 폴리우레탄 시트가 신장되어 발생되는 제반 문제점을 해결할 수 있다는 효과가 있다.As described above, according to the present invention, since the polyurethane sheet is manufactured from polyurethane gloves, the manufacturing process is simple, and in particular, it is possible to provide a polyurethane glove that can ensure good breathability and elasticity, excellent sensitivity and grounding properties. There is an advantage. In addition, since the polyurethane gloves are provided by the continuous rotating molding roller rather than the press method, the manufacturing time is shortened, thereby reducing the manufacturing cost. Furthermore, since the non-elastic paper sheet paper is simultaneously transferred to the bottom of the polyurethane sheet paper, there is an effect that it is possible to solve various problems caused by stretching the polyurethane sheet.
