[발명의 목적][Purpose of invention]
본 발명은 신발용 밑창표면에 아름다운 다색무늬를 코팅하기 위해 최초로 개발된 다색무늬자동코팅공정을 제공함이 목적이다.An object of the present invention is to provide a multi-color pattern automatic coating process first developed to coat a beautiful multi-color pattern on the sole surface for shoes.
[종래기술의 문제점][Problems with Prior Art]
신발용 밑창 표면에 다색무늬를 형성시키기 위해 행하여 졌던 종래의 기술은 대략 세가지로 구분되어있다. 이에 각 기술별로 실시방법 및 문제점을 설명한다.The prior art, which has been done to form multicolored patterns on sole surfaces of shoes, is roughly divided into three. This will describe the implementation method and problems for each technology.
A. 스티커열전사 방식A. Sticker thermal transfer method
이 방법은 신발용 밑창(101)의 원하는 스티커를 부착시킨 다음 이에 열을 가하여 잉크층을 밑창(101)표면에 코팅되게 한 후 스티커를 데어 내는 것인데 일일이 수작업을 통해야 하므로 작업성이 불량하고 생산속도가 양호치 못하여 작업결과 또한 작업자의 숙련도에 따라 약간씩 차이가 나서 제품의 질이 일정치 못한 문제가 있다.This method is to attach the desired sticker of the shoe sole 101 and apply heat to it so that the ink layer is coated on the surface of the sole 101, and then the sticker is burned out. There is a problem that the quality of the product is not good because the work results are also slightly different depending on the skill of the operator.
B. 스프레이 방식B. Spray Method
이 방식은 밑창(101)의 표면에 구성시키고자 하는 무늬형태대로 밑판을 일일이 제작한 다음 이를 밑창(10)에 부착시킨 후 원하는 색상을 스프레이하는 것인데, 섬세하거나 예민한 무늬는 실시하기가 대단히 어렵고 서로의 색상이 접하는 경계가 깨끗히 못하여 제품의 질이 저하되고 이 역시 생산성, 작업성이 불량한 문제가 있다.This method is to produce the sole plate in accordance with the pattern to be configured on the surface of the sole 101, then attach it to the sole 10 and spray the desired color, delicate or sensitive pattern is very difficult to implement each other The quality of the product is degraded because the boundary of the color is not clean, and this also has a problem of poor productivity and workability.
C. 퍼드방식(스탬핑 방식)C. Pudding (Stamping)
이 방식은 밑창(101)의 외표면의 3차적 곡률과 동일하게 스템핑금형을 제작하여 스템핑금형을 표면에 잉크를 도포한 다음 열을 가하여 밑창 표면에 압착시켜 줌으로서 코팅을 하는 것인데 이 방식 또한 작업성, 생산성, 정교성 등이 불량하여 해결책이 요구되었다.This method is to make the stamping mold in the same way as the third curvature of the outer surface of the sole 101, apply the ink to the surface of the stamping mold and then apply heat to compress the surface of the sole to apply the coating. In addition, workability, productivity, elaboration, etc. are poor, so a solution was required.
[발명의 구성][Configuration of Invention]
이송체인(2)에 의해 계속적인 일방진행을 하고 있는 행거(3)에 다수개의 밑창(101)을 협착시킨 밑창 협착지그(4)를 재치시키면 이는 이송이 되어 푸셔(5)의 전방에 이르게 되고 이와 동시에 푸셔(5)의 푸싱(pushing)운동에 의해, 대기하고 있는 로봇 암(6)에 밑창 협착지그(4)가 전달이 되고 역시 이와 동시에 로봇 암(6)은 정해진 프로그램에 의해 PVA필름(12)과 잉크층(13)이 연화되어 떠있는 수조(10)의 상부로 이동이 되어 밑창(101) 표면에 코팅작업을 하게 되며 이 작업이 끝나면 대기중인 리시버(15)에 밑창 협착지그(4)를 전달하게 되고 이와 동시에 리시버(15)는 180°회전하여 역시 일방진행을 하고 있는 이송체인(2a)의 행거(3a)에 밑창 협착지그(4)를 전달하게 되며 이때부터 밑창 협착지그(4)에 협착되어 있는 코팅된 밑창(101)은 수세실(16)을 거쳐 PVA필름(12)을 깨끗이 세척하고 공기분사관(17)을 거치면서 잔존 수분을 탈취시킨 후 열풍건조기(18)를 통해 수분을 완전히 건조시켜서 코팅재분사장치(19)를 통과하면서 잉크층(13)보호코팅재를 코팅한 후 열풍건조기(21)를 거쳐 완성품보관실(22)로 가서 완성이 된다.If the sole narrowing jig (4) in which a plurality of soles (101) are squeezed is placed on the hanger (3) which is continuously making one-way progress by the conveying chain (2), it is transferred and reaches the front of the pusher (5). At the same time, the sole narrowing jig 4 is transferred to the robot arm 6 that is waiting by the pushing motion of the pusher 5, and at the same time, the robot arm 6 uses the PVA film ( 12) and the ink layer 13 is softened and moved to the upper portion of the floating tank 10 to coat the surface of the sole 101, and when this operation is completed, the sole narrowing jig (4) on the receiver 15 is waiting. At the same time, the receiver 15 rotates 180 ° and transmits the sole narrowing jig 4 to the hanger 3a of the transfer chain 2a, which is still one-way. The coated sole 101, which is squeezed on the bottom surface, cleans the PVA film 12 through the wash chamber 16. After washing and deodorizing the remaining moisture while passing through the air spray pipe (17), the moisture is completely dried by the hot air dryer (18) to pass through the coating material spraying device (19) to coat the ink layer (13) protective coating material and then hot air The dryer 21 goes to the finished product storage room 22 and is completed.
[실시예]EXAMPLE
수조(10)에 물(11)을 거의 가득 채운 뒤 히터(102)를 이용하여 물의 온도를 30-40℃가 되도록 유지시킨 다음, 코팅필름공급기(8)를 이용하여 사각형태의 PVA필름(12)을 데워진 물(11)의 표면에 평평하게 투입시킨 후 30-50초가 경과되니 PVA필름(12)이 녹아서 젤리상태가 되었다.After the water tank 10 is almost filled with water 11, the temperature of the water is maintained at 30-40 ° C. using the heater 102, and then the PVA film 12 having a rectangular shape is formed using the coating film feeder 8. ) Was put flat on the surface of the heated water (11) and 30-50 seconds elapsed, so that the PVA film (12) melted and became jelly.
이때 PVA필름(12)의 연성과 접착력에 의해 PVA필름(12)의 표면에 구성되어 있던 잉크층(13)이 흩어지지 않고 유지됨을 알 수 있었다. (PVA필름(12)의 접착력에 의함)At this time, it was found that the ink layer 13 formed on the surface of the PVA film 12 was maintained without being scattered due to the ductility and adhesion of the PVA film 12. (By adhesion of PVA film 12)
다음, 합성톨루엔을 약간량 분사노즐(9)을 통해 분사시켜서 고체상태로 PVA필름(12)위에 떠 있던 잉크층(13)을 액체화시켜 연화시켰는데 이때도 제2도와 같이 PVA필름(12)위에서 무늬를 잘 유지한 채 보관되어 있었다.Next, the synthetic toluene was sprayed through a small amount of the injection nozzle 9 to soften the liquid layer of the ink layer 13 floating on the PVA film 12 in a solid state. It was kept in good condition.
다음, 푸셔(5)에 의해 전달받은 밑창협착지그(4)를 로봇암(6)이 인수하여 밑창(10)의 잉크층(13)과 PVA필름(12)이 코팅되게 하였는데 제3a도와 같이 입사각을 30˚로 유지한 채 밑창(101)의 뒷굼치부분 부터 입사시켜 b, c, d, e 그리고 f의 상태까지 물(11)의 표면위를 구르듯이 실시하였더니 물(11)위에 떠 있던 잉크층(13)과 PVA필름(12)이 밑창(101)의 표면에 잘 코팅되어 접착되었다. 이때 PVA필름(12)은 물(11)과 잉크층(13)을 잘 분리시켜 주는 역할을 한다는 사실을 발견하였다.Next, the robot arm 6 took over the sole stenosis jig 4 transmitted by the pusher 5 so that the ink layer 13 and the PVA film 12 of the sole 10 were coated. Was kept at 30 ° from the rear ridge of the sole 101 and then rolled on the surface of the water 11 to b, c, d, e and f. Layer 13 and PVA film 12 were well coated and adhered to the surface of sole 101. At this time, the PVA film 12 was found to play a role of separating the water 11 and the ink layer 13 well.
제3a부터 f도까지의 과정을 준수한 결과 밑창(101)의 오목한 부분과 3차곡선이 구성된 부분, 볼록하게 나온 부분등이 매우 양호한 상태로 골고루 잘 코팅이 되었다. 즉, 물(11)의 부드러운 부력으로 인해 PVA필름(12)과 잉크층(13)은 부담없이 밑창(101) 표면에 코팅된 것이다.As a result of adhering to the process from 3a to f degree, the concave portion of the sole 101, the portion composed of the third curve, the convex portion, etc., were coated evenly in a very good state. That is, due to the soft buoyancy of the water 11, the PVA film 12 and the ink layer 13 is casually coated on the sole 101 surface.
이때 무늬의 크기나 모양에 변형이 없었다. 여기서, 입사각유지 및 코팅고정을 준수치 않고 수직으로 또는 수평으로 밑창(101)을 침수시켜 보았는데 밑창(101)의 표면에 잉크층(13)과 PVA필름(12)이 코팅이 되기는 하였으나 물(11)의 표면을 구르듯이 부드럽게 코팅공정을 거친 전술한 방법에 의한 것보다는 코팅상태가 불량하였다.At this time, there was no deformation in the size or shape of the pattern. Here, the sole 101 was immersed vertically or horizontally without adhering to the angle of incidence and the fixing of the coating. However, although the ink layer 13 and the PVA film 12 were coated on the surface of the sole 101, water (11) was applied. The coating state was poorer than that by the above-described method, which was subjected to the coating process smoothly, as if rolling the surface.
즉, PVA필름(12)과 잉크층(13)이 당겨지고 일그러져서 1:1의 코팅이 되지 않아 잉크층(13)의 무늬가 각 부분마다 당겨지고 늘어나는등 불량이 속출되었다. 따라서 제3a부터 e까지의 코팅운동은 대단히 중요하다는 결론을 얻었다.That is, since the PVA film 12 and the ink layer 13 are pulled and distorted, the coating of the ink layer 13 is not drawn because of a 1: 1 coating. Therefore, it was concluded that the coating motion from 3a to e is very important.
이 과정을 거친 밑창(101)은 수세실(16)로 들어가 잉크층(13)만 남긴 채 PVA필름(12)을 깨끗하게 수세하게 되는데 약 3-5분이 경과되었고, 이를 통과한 것을 공기분사관(7)을 통해 10초정도 물방울을 날려 버린 후 열풍건조기(18)를 통과하게 하여 20-30분 동안 완전건조시켰다.The sole 101, which has undergone this process, enters the wash chamber 16 and washes the PVA film 12 cleanly, leaving only the ink layer 13, and it takes about 3-5 minutes to pass through the air injector ( 7) was blown for about 10 seconds and then passed through the hot air dryer (18) and completely dried for 20-30 minutes.
다음, 잉크층(13)의 내구성유지를 위해서 1액형바니솔계통의 투명코팅제를 코팅제분사장치(19)에서 1-2분간 분사코팅하여 열풍건조기(21)을 통해 15-25분간 열풍건조시켜 완성하였다.Next, in order to maintain the durability of the ink layer 13, a one-component varnish-based transparent coating agent is spray-coated for 1-2 minutes in the coating spraying device 19, and then hot-air-dried for 15-25 minutes through the hot air dryer 21 to be completed. It was.
이 실시예를 통해 완성된 잉크층(13) 코팅상태는 내마모성, 연신율, 코팅유지력등이 매우 양호하다.The coating state of the ink layer 13 completed through this embodiment is very good in wear resistance, elongation, coating holding power and the like.
상술한 바와 같은 본 발명은 종래의 비능률적인 수작업에 의한 코팅방법에서 완전히 탈피하여 생산성 향상, 제품상태양호, 불량률제로 등의 큰 효과를 얻을 수 있는 신발용 밑창표면의 다색무늬자동코팅공정으로서 현재 수출부진과 자동화결핍, 새로운 아이디어의 공급부족 현상이 시달리고 있는 신발제조업에 큰 활력을 불어 넣을 수 있는 참신한 발명이다.The present invention as described above is currently exported as a multi-colored pattern automatic coating process of the sole surface for shoes that can be completely escaped from the conventional inefficient manual coating method to obtain a large effect such as improved productivity, good product condition, zero defect rate, etc. It is a novel invention that can give vitality to the shoe manufacturing industry, which is suffering from sluggishness, lack of automation and lack of new ideas.
