이후, 본 발명에 따른 복대제조방법은 본 출원인의 특허출원 제2004-43547호 설명된 복대제조방법에 소개된 공정과 유사하다.Thereafter, the bag manufacturing method according to the present invention is similar to the process introduced in the bag manufacturing method described in the applicant's patent application 2004-43547.

즉, 도 2에 도시된 바와같이, 상부금형(20)이 장착된 고주파웰딩장치(30)에 하부외피(101), 하부내피(103), 탄성밴드(110), 상부내피(105), 상부외피(107)가 순서대로 적층된 하부금형(10)을 배치하고, 상부금형(20)을 하강시켜 하부외피(101), 하부내피(103), 상부내피(105), 상부외피(107)를 접합시킨다(S102).
이때, 도 7에 도시된 바와같이, 고주파웰딩장치에 하부외피, 하부내피, 상부내피, 상부외피가 접합된 복대 반제품(100a)은 탄성밴드(110)의 양측부에 근접하게접합부(125)가 형성되므로서, 상기 접합부(125) 사이에 탄성밴드(110)가 위치한 비접합 부위가 공기통로(127)가 된다. 이것에 의해 접합부(125)와 공기통로(127)가 복대 반제품(100a)에 교대로 형성된다. 또한, 상기 접합부(125)는 비접합부(129)를 포함하여 복대의 어느 한 쪽으로 에어를 주입하면, 접합부(125) 사이의 공기통로(127) 전체로 공기가 공급되게 된다.That is, as shown in Figure 2, the lower mold 101, the lower endothelial 103, the elastic band 110, the upper endothelial 105, the upper portion of the high frequency welding device 30 is equipped with an upper mold 20 The lower mold 10 in which the outer shell 107 is stacked in this order is disposed, and the upper mold 20 is lowered to lower the lower outer shell 101, the lower inner shell 103, the upper inner shell 105, and the upper outer shell 107. Bonding (S102).
At this time, as shown in Figure 7, the banded semi-finished product (100a) is bonded to the lower outer shell, lower inner shell, upper inner shell, the upper outer shell to the high-frequency welding device, the junction portion 125 is close to both sides of the elastic band 110 As it is formed, the non-bonded portion in which the elastic band 110 is located between the junction portion 125 becomes the air passage 127. Thereby, the junction part 125 and the air passage 127 are alternately formed in the bag semifinished product 100a. In addition, when the air is injected into one of the bags including the non-junction 129 and the junction 125, the air is supplied to the entire air passage 127 between the junctions 125.

상기 상부금형(20)은 본 출원인의 특허출원 제2004-43547호에 자세하게 설명되어 있어 여기서 자세한 설명은 생략하기로 한다.The upper mold 20 is described in detail in the applicant's patent application No. 2004-43547, the detailed description thereof will be omitted.

이후, 도 3에 도시된 바와같이, 신장되었던 탄성밴드(110)가 수축되면서 상기 복대 반제품(100a)에 길이방향으로 주름(111)이 형성되도록, 상기 하부금형을 고주파웰딩장치에서 꺼낸 후, 하부외피, 하부내피, 상부내피, 상부외피가 접합된 복대 반제품(100a)을 목형(50)과 분리함으로서, 탄성밴드(110)를 목형(50)에서 분리한다(S103). 이와같이, 탄성밴드(110)를 목형(50)에서 분리하면, 자동으로 복대 반제품(100a)이 목형(50)에 탈락된다. 이것은 복대 반제품(100a)과 목형(50)이 탄성밴드(110)에 의해 연결되어 있기 때문이다. 이때, 환 형태의 탄성밴드(110)가 복대 반제품(100a)의 접합부(125) 상단 및 하단에 걸린 상태에서 수축되기 때문에 복대 반제품(100a)에 길이방향으로 주름(111)이 형성된다.
또한, 도 1c에 도시된 탄성밴드(110')의 경우, 상기 탄성밴드(110')의 양단에 매듭을 만든 후, 상기 탄성밴드(110')를 목형(50)에서 분리하면, 탄성밴드(100')가 수축되면서, 상기 탄성밴드가 복대 반제품의 접합부 상단 및 하단에 걸리게 되므로서, 복대 반제품에 길이 방향으로 주름이 형성된다.Thereafter, as shown in FIG. 3, the lower mold is removed from the high frequency welding apparatus so that the wrinkles 111 are formed in the longitudinal direction on the bag semi-finished product 100a while the elastic band 110 that is stretched is contracted. By separating the banded semi-finished product (100a) is bonded to the outer shell, lower endothelial, upper endothelial, upper outer shell and the 50, the elastic band 110 is separated from the mold 50 (S103). As such, when the elastic band 110 is separated from the die 50, the bag semi-finished product 100 a is automatically dropped onto the die 50. This is because the bag semifinished product 100a and the die 50 are connected by the elastic band 110. At this time, since the elastic band 110 of the annular shape is contracted in the state caught in the upper and lower ends of the junction portion 125 of the bag semi-finished product (100a), wrinkles 111 are formed in the longitudinal direction of the bag semi-finished product (100a).
In addition, in the elastic band 110 ′ shown in FIG. 1C, after knots are formed at both ends of the elastic band 110 ′, the elastic band 110 ′ is separated from the die 50. 100 ') is contracted, the elastic band is caught on the top and bottom of the junction of the semi-finished product, the wrinkles formed in the longitudinal direction of the semi-finished product.

이후, 도 3에 도시된 바와같이, 복대 반제품(100a)이 충분이 냉각된 상태에서 탄성밴드(110)를 복대 반제품에서 제거한다(S104). 상기 탄성밴드(110)는 어느 한 부분을 절단하여 잡아당기면 복대 반제품(100a)에서 쉽게 빠지게 된다.Thereafter, as shown in FIG. 3, the elastic band 110 is removed from the bag semifinished product while the bag semifinished product 100a is sufficiently cooled (S104). The elastic band 110 is easily pulled out of the bandage semi-finished product (100a) by cutting any part.

이후, 도 4에 도시된 바와같이, 탄성밴드에 의해 복대 반제품(100a)의 상부 테두리부(121)와 하부 테두리부(123)에 형성된 개구부가 밀폐되도록, 복대 반제품(100a)의 상부 테두리부(121)와 하부 테두리부(123)를 소형 고주파 웰딩장치(도시하지 않음)로 접합한다(S105). 이것에 의해, 도 6에 도시된 바와같이, 복대(100)에 에어를 주입하면, 통기로(115)로 공급된 에어가 외부로 누설되지 않는다.Thereafter, as shown in FIG. 4, the upper edge portion of the bag semifinished product 100a is sealed so that an opening formed in the upper edge portion 121 and the lower edge portion 123 of the bag semifinished product 100a is sealed by an elastic band ( 121 and the lower edge portion 123 are bonded with a small high frequency welding device (not shown) (S105). Thereby, as shown in FIG. 6, when air is inject | poured into the bag 100, the air supplied to the ventilation path 115 does not leak outside.

이후, 도 5에 도시된 바와같이, 복대 반제품을 복대(100)의 형상으로 재단하고, 에어주입구(130)를 장착하는 등의 마무리 작업을 수행하여 복대 완제품(100)을 완성한다(S106).Thereafter, as shown in FIG. 5, the bandage semi-finished product is cut into the shape of the bag 100, and a finishing operation such as mounting an air inlet 130 is performed to complete the finished bag 100 (S106).

위에서 설명한 바와같이, 본 발명에 따른 복대제조방법은 목형의 핀고리에 탄성밴드를 인장시켜 거는 작업을 일련의 복대제조공정과 별도로 진행함으로서, 탄성밴드를 핀고리에 거는 작업시간을 일련의 복대제조공정시간에 포함시키지 않아도 되기 때문에 전체 제조작업시간을 단축할 수 있고, 목형에 의해 하부외피와 하부내피가 구김없이 언제나 평평하게 하부금형에 배치될 수 있는 효과가 있다.As described above, the method of manufacturing a bag according to the present invention is performed by stretching the elastic band to the pin pin of the wooden mold separately from a series of bags manufacturing process, a series of bags manufacturing work time to hang the elastic band to the pin ring Since it does not need to be included in the process time, the entire manufacturing operation time can be shortened, and the lower shell and the lower endothelial can be arranged in the lower mold at any time without wrinkles by the wooden die.
