본 발명은 스폰지로서 신발창을 제조하는 과정에서 스폰지스크랩, 즉 로스의 발생을 최대한 감소시키는 스폰지스크랩로스를 절감하는 신발창의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a shoe sole to reduce the sponge scrap to reduce the occurrence of sponge scrap, that is, the loss in the process of manufacturing the sole as a sponge.

종래에는 신발창을 제조함에 이었어 첨부도면 제2도에 도시하고 있는 바와같이제2(a)도원료 및 약품등을 혼합한 혼합물(a)을 제2(b)도 로울러 (b)에 의해서 일정두께로 압연하고 제2(c)도 금형(c)에 넣어서 프레스로서 가압하여 대형 스폰지시트(d)로 발포시킨후 제2(d)도 이와같이 발포된 스폰지시트(d)를 제2(e)도 가열로 인한 상하면의 불규칙하고 깨끗하지 못한면을 스카이빙(skiving)하고 제2(f)도다시 불규칙한 둘레를 절단하여 신발창을 만들 수 있는 크기로 분할한후 제2(g)도와 같이 재단하여 연마하므로서 신발창을 완성하게 되는바 상술한 공정에서 보는 바와같이 제2(e)도, 제2(f)도, 제2(g)도의 공정에서 상하표면과 사면둘레 및 창을 재단하고 남은 스크랩(E)의 양이 거의 절반에 가까운 많은 양이므로 생산원가가 비싸 소비자가격이 고가일뿐 아니라 생산회사의 경제적 손실이 많은 폐단이 있었다.Conventionally, in the manufacture of shoe soles, as shown in Fig. 2 of the accompanying drawings, the thickness of the mixture (a) in which the raw material and the chemicals are mixed (a) with the roller (b) is also fixed to a certain thickness. Rolled into a mold (c), pressurized as a press, and then foamed into a large sponge sheet (d). Skiving the irregular and unclean surface of the upper and lower surfaces due to heating, and after dividing the irregular circumference into the size that can make the soles by cutting the irregular circumference again, it is cut and polished as shown in the second (g). As a result, the shoe sole is completed. As shown in the above-described process, the scrap remaining after cutting the upper and lower surfaces, the perimeter of the window, and the window in the processes of 2 (e), 2 (f), and 2 (g) is obtained. ) Is almost half, so production costs are high, and the consumer price is not only high. The company economic loss there were many evils.

뿐만 아니라 이와같이 발생된 스크랩은 모두 폐기처분해야 되는데 소각시 산업공해를 유발하므로 처분에 큰 문제점을 주고 있는 또한 일부에서는 이를 재활용하기 위해 스크랩에 원료를 혼합하여 재생스폰지를 만들고 있으나 색상, 탄성등 품질이 좋지 못하여 고가품이나, 수출용으로는 적합하지 못하므로 사용 용도가 극히 제한되어 있는등 스크랩의 처리에 큰 과제가 되고 있었다.In addition, all the scraps generated in this way have to be disposed of, which causes industrial pollution when incinerated. In some cases, recycled sponges are mixed by mixing raw materials with scraps to recycle them. Since it is not good, it is not suitable for expensive goods or for export, which has been a major problem in the treatment of scrap, such as its use is extremely limited.

따라서 본 발명의 일차적 목적은 제조공정에서 스크랩, 즉 로스가 발생하지 않는 새로운 제조공정을 제공하는데 있는 것이다. 또 본 발명의 목적은 생산원가를 절감하므로서 경제적 손실을 감소시키고자 하는데 있다.It is therefore a primary object of the present invention to provide a new manufacturing process in which no scrap, ie, loss, occurs in the manufacturing process. In addition, an object of the present invention is to reduce the economic loss by reducing the production cost.

또 본 발명의 목적은 스폰지 창을 제조하는 작업공정을 감소시켜 생산성의 향상을 꾀하고자하는데 있는 것이다.In addition, an object of the present invention is to reduce the work process for manufacturing a sponge window to improve the productivity.

이한 본 발명을 첨부한 도면에 의거 상세히 설명하면 다음과 같다. 원료 발포제등 각종 약품등을 믹싱롤(1)에서 혼합하여 형성된 생지(2)를 카렌다를(3)에 의해 판상으로 압연하는것에 있어서 압연된 판상의 생지(2)를 발포시 신발창(4)의 크기로 형성될 수 있는 세편(5)(5')으로 절단하여 다수의 형공(6)이 형성된 금형(7)에 넣어 프레스로서 가압발포시킨 후 발포된 성형물(4')을 그라인더(8)에 의해 측면을 연마하고 다시 바핑롤(buffing roll)(9)로서 상하두께를 조절하여 신발창(4)을 완성함을 특징으로 하는 것이다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In rolling the dough (2) formed by mixing various chemicals such as a raw material blowing agent in the mixing roll (1) into a plate by calender (3), when the rolled plate-like dough (2) is foamed, Cut into three pieces (5) (5 ') that can be formed in size, put into a mold (7) formed with a plurality of mold holes (6) and pressurized and foamed as a press and then the foamed molding (4') to the grinder (8) By grinding the side by the backing (buffing roll) (9) is characterized by completing the sole 4 by adjusting the upper and lower thicknesses.

도면중 미설명부호 10은 겉창이다.In the figure, reference numeral 10 is an outsole.

이와같이 된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

첨부도면에 도시하 제1(a)도, 제1(b)도의 공정순서는 종래의 공정과 동일하나 본 발명은 카렌다를(3)에 의해 판상으로 압연된 생지(2)를 종래와 같이 바로 금형(7)에 넣어 발포시키지 아니하고 발포시 신발창(4)의 크기로 될 수 있는 정도의 세편(5)(5')으로 미리 절단하여 다수개의 신발창 성형용 형공(6)을 형성한 금형(7)에서 신발창(4)의 형태로 선발포 시키는데 특징이 있는 것인바 이와같이 금형(7)에서 신발창(4)의 형태로 발포된 성형몰(4')은 거의 신발창(4)의 형상을 가지게되나 상하표면 및 측면둘레가 고르지 못하므로 이 고르지 못한 성형물(4')을 일차 그라인더(8)에 이해서 측면둘레를 연마시키고 이어서 상하 바핑롤(9)로 표리면 및 두께를 조정하면 신발창(4)이 완성되어지므로 종래 공정에서와 같이 스크랩(E)이 전혀 발생하지 않으며 재료의 손실은 그라인더(8) 및 바핑롤(9)에 의해 연마시 극히 소량 발생되는 정도이다.The process sequence of FIG. 1 (a) and FIG. 1 (b) shown in the accompanying drawings is the same as the conventional process, but the present invention immediately transfers the dough 2 rolled into the plate by calender 3 as in the prior art. Mold (7) formed by molding a plurality of sole moldings (6) by cutting in advance into three pieces (5) (5 ') that can be the size of the sole 4 when foaming without foaming in the mold (7) It is characterized in that the pre-foamed in the form of the sole (4) in the bar as described above, the molding mould (4 ') foamed in the form of the sole 4 in the mold (7) has almost the shape of the sole 4, but Since the surface and side circumference are uneven, this uneven molding 4 'is polished to the side of the primary grinder 8 and then the side circumference, and then the top and bottom baping rolls 9 adjust the front and back sides and the sole 4 As it is completed, no scrap (E) occurs as in the conventional process, and the loss of material The binder 8 and the bar is about to be generated is extremely small at the time of polishing by pingrol 9.

본 출원인의 본 발명에 의한 방법으로 실험한바에 의하면 스폰지로스량은 전체의 약 12.361%정도이었는바 이 손실량은 종래의 48.22%인것에 비하면 약 4배정도에 로스발생율이 감소됨을 알수 있었고 그 절감율은 약 35.859%이다.According to the present inventors' experiment according to the method of the present invention, the amount of sponge loss was about 12.361%, and the loss amount was about 4 times compared to the conventional 48.22%. 35.859%.

현재의 일반적인 스폰지 1kg당 원가는 약, 1,064원 정도이므로 예를들어 한회사에서 스폰지의 년간소요량이 약 2, 000, 000Kg을 소요한다고 볼때 종래의 방법에 의한 년간 로스발생 추정금액은 2,000,000×48. 22%×1,064Kg=10억 2원만원 정도이고 본 발명에 의하면 2,000,000×12.361%×1,064Kg=2억 5원만원이므로 년간 로스절감액은 약 7억 5천만원 정도임이 계산상 명확히 산출되는 것이므로 생산원가가 대량 절감되어 생산회사의 경제적 이득은 물론 소비자가격도 대폭 저하될 수 있는 것이다.Currently, the cost per 1kg of sponge is about 1,064 won, so for example, if a company needs about 2, 000, 000kg of sponge, the estimated annual loss is 2,000,000 × 48. Since 22% × 1,064Kg = 1.02 billion won and 2,000,000 × 12.361% × 1,064Kg = 250 million won, the annual loss reduction is about 750 million won, so the production cost is clearly calculated. The large savings in oil prices could lead to a significant drop in the economic benefits of the producers as well as in consumer prices.

이와같은 본 발명은 제조과정에서 로스의 발생률이 종래에 비해 히 극히 소량이므로 원가가 절감되고, 약 2-3가지 저도의 작업공정이 생략되므로 생산성이 향상될뿐 아니라 스크랩의 발생이 감소되어 산업공해의 발생을 저하시키는 등의 효과가 매우 큰 유용한 발명이다.In the present invention, the production rate of the loss in the manufacturing process is very small compared to the conventional cost is reduced, and about 2-3 low-level work process is omitted, not only to improve the productivity but also reduce the occurrence of scrap industrial pollution It is a very useful invention which is very effective in reducing the occurrence of.
