또한, 최근에는 인터넷의 발달과 함께, 물품 거래가 판매자와 구매자 간의 대면방식에서, 네트워크를 이용하여 원격지의 판매자와 구매자 간의 거래 계약이 체결되고, 물류시스템을 통해 판매자의 상품이 구매자에게 전달되는 방식으로 거래 패턴이 변화되고 있다. 이를 위해, 물품의 포장지에는 판매자와 구매자의 주소 등의 정보를 기입하며, 배송 과정 중에 충격 등에 의해 물품이 손상되는 것을 방지할 필요가 있다. 이를 위하여 상품을 시트를 사용하여 파손을 방지할 수 있다. 이러한 상기와 같은 경우 이외에도 시트는 창문 등에 이를 부착함으로써 단열을 하거나 상하기 쉬운 음식을 보관하기 위하여 사용될 수 있다. In recent years, with the development of the Internet, the merchandise trading is face-to-face between the seller and the buyer, the transaction contract between the seller and the buyer is established through the network, and the seller's goods are delivered to the buyer through the logistics system. Trading patterns are changing. To this end, it is necessary to write information such as addresses of sellers and buyers on the packaging of the goods, and to prevent the goods from being damaged by shocks or the like during the delivery process. For this purpose, the product can be prevented from being damaged by using a sheet. In addition to the above cases, the sheet may be used for storing food which is easily insulated or damaged by attaching it to a window or the like.

상기와 같은 주사부(133)는 다양한 형태로 배열될 수 있다. 예를 들면, 일 실시예로써 주사부(133)는 하나만 구비되어 연결부(132)를 시트(200)의 폭 방향으로 선형 운동하면서 삽입물질(230)을 에어포켓부(220)에 주입할 수 있다. 다른 실시예로써 주사부(133)는 복수개 구비되어 시트(200)이 폭 방향으로 서로 이격되도록 배열될 수 있다. 이때, 주사부(133)는 시트(200)의 폭보다 좁게 형성되어 일정한 영역에만 삽입물질(230)을 주사할 수 있다. 또 다른 실시예로써 주사부(133)는 복수개 구비되며, 시트(200)의 폭 방향의 에어포켓부(220)의 개수와 동일한 숫자로 서로 이격되도록 배열되는 것도 가능하다. 또 다른 실시예로써 주사부(133)는 복수개 구비되어, 시트(200)의 폭 방향 뿐만 아니라 시트(200)의 길이 방향으로 서로 이격되도록 배열되는 것도 가능하다. 상기와 같은 주사부(133)는 상기와 같은 배열에 한정되는 것은 아니며, 일정한 도형, 문자, 이미지 등과 같이 배열되는 것도 가능하다. 다만, 이하에서는 설명의 편의를 위하여 주사부(133)가 시트(200)의 폭 방향으로 배열된 에어포켓부(220)의 개수와 동일한 숫자로 시트(200)의 폭 방향과 길이 방향으로 일정 영역에 배열되는 경우를 중심으로 상세히 설명하기로 한다. The scan unit 133 as described above may be arranged in various forms. For example, as an example, only one injection unit 133 may be provided to inject the insertion material 230 into the air pocket 220 while linearly moving the connection unit 132 in the width direction of the sheet 200. . In another embodiment, a plurality of scanning units 133 may be provided such that the sheets 200 are spaced apart from each other in the width direction. In this case, the scanning unit 133 may be formed to be narrower than the width of the sheet 200 to scan the insertion material 230 only in a predetermined region. As another embodiment, a plurality of scanning units 133 may be provided and arranged to be spaced apart from each other by the same number as the number of the air pockets 220 in the width direction of the sheet 200. In another embodiment, a plurality of scanning units 133 may be provided and arranged to be spaced apart from each other in the longitudinal direction of the sheet 200 as well as the width direction of the sheet 200. The scan unit 133 as described above is not limited to the above arrangement, and may be arranged as a predetermined figure, character, or image. However, hereinafter, for convenience of description, the scan unit 133 may have the same number as the number of the air pockets 220 arranged in the width direction of the sheet 200 in the width direction and the length direction of the sheet 200. The case will be described in detail with respect to the case.

The hardening unit 150 may harden the reinforcing material 240. At this time, the curing unit 150 may cure the reinforcing material 240 in a variety of ways. For example, the hardening unit 150 may harden the reinforcing material 240 by applying a predetermined heat. In addition, the curing unit 150 may cure the reinforcing material 240 by irradiating the reinforcing material 240 with ultraviolet light. The reinforcing material 240 may include a thermosetting material or a material that is cured when ultraviolet rays are irradiated.

In this case, the roller unit 120 may be in a state in which the sheet 200 is wound.
시트(200)를 펼친 후 이송부(180)를 작동시키면, 시트(200)가 이동할 수 있다. 상기와 같이 시트(200)가 이송되는 경우 주입부(130)는 시트(200)의 에어포켓부(220)에 삽입물질(230)을 주입할 수 있다. 이때, 삽입물질(230)은 상기에서 설명한 것과 같이 일정한 패턴, 일정한 문양, 일정한 글자 등을 형성하도록 특정한 에어포켓부(220)에만 주입될 수 있다. 다른 실시예로서 삽입물질(230)은 시트(200)에 형성된 에어포켓부(220) 전체에 주입되는 것도 가능하다. 다만, 이하에서는 설명의 편의를 위하여 시트(200)에 형성된 에어포켓부(220) 전체에 삽입물질(230)이 주입되는 경우를 중심으로 상세히 설명하기로 한다. When the conveyer 180 is operated after unfolding the sheet 200, the sheet 200 may move. When the sheet 200 is transferred as described above, the injection unit 130 may inject the insertion material 230 into the air pocket 220 of the sheet 200. In this case, the insertion material 230 may be injected only to the specific air pocket 220 to form a predetermined pattern, a predetermined pattern, a predetermined letter, and the like as described above. In another embodiment, the insertion material 230 may be injected into the entire air pocket 220 formed in the sheet 200. However, hereinafter, a description will be given in detail focusing on the case where the insertion material 230 is injected into the entire air pocket 220 formed in the sheet 200 for convenience of description.
상기와 같이 에어포켓부(220)에 삽입물질(230)을 주입하는 방법은 우선 주사부(133)를 하강시켜 에어포켓부(220)에 주사부(133)의 일부를 삽입한 후 삽입물질저장부(131)에서 삽입물질(230)을 연결부(132)를 통하여 주사부(133)로 공급할 수 있다. 이때, 주사부(133)에서는 삽입물질(230)의 공급으로 인하여 삽입물질(230)이 에어포켓부(220) 내부로 공급될 수 있다. As described above, the method of injecting the insertion material 230 into the air pocket 220 includes first lowering the injection part 133 to insert a part of the injection part 133 into the air pocket part 220 and then storing the insertion material. In the portion 131, the insertion material 230 may be supplied to the injection portion 133 through the connection portion 132. At this time, in the injection unit 133, the insertion material 230 may be supplied into the air pocket 220 due to the supply of the insertion material 230.
상기와 같이 에어포켓부(220)에 삽입물질(230)의 주입이 완료되면, 이송부(180)가 작동하여 시트(200)를 이송시킬 수 있다. 이때, 보강물질도포부(140)는 보강물질(240)을 시트(200) 상에 도포할 수 있다. 구체적으로 보강물질도포부(140)는 시트(200) 상에 보강물질(240)을 낙하시킬 수 있다. 특히 삽입물질(230)이 주입된 에어포켓부(220)는 주입홀(221) 등이 형성되어 외부와 연통되므로 삽입물질(230)이 에어포켓부(220)로부터 유출될 수 있다. 이때, 상기와 같이 보강물질(240)을 낙하시킴으로써 에어포켓부(220)의 주입홀(221)을 보강물질(240)로 막을 수 있다. As described above, when the injection of the inserting material 230 into the air pocket 220 is completed, the transfer unit 180 may operate to transfer the sheet 200. In this case, the reinforcing material applying unit 140 may apply the reinforcing material 240 on the sheet 200. In detail, the reinforcing material applying unit 140 may drop the reinforcing material 240 on the sheet 200. In particular, the air pocket portion 220 into which the insertion material 230 is injected is formed so that the injection hole 221 and the like communicate with the outside so that the insertion material 230 may flow out of the air pocket portion 220. At this time, by dropping the reinforcing material 240 as described above it can block the injection hole 221 of the air pocket portion 220 with the reinforcing material 240.
상기와 같은 경우 보강물질도포부(140)는 도포부(142)가 가이드부(141)를 따라 선형 운동하면서 삽입물질(230)이 주입된 에어포켓부(220) 상에만 보강물질(240)을 공급할 수 있다. 이때, 삽입물질(230)이 주입된 에어포켓부(220)를 구분하는 방법은 삽입물질(230)의 주입한 형태가 기 설정된 상태일 수 있으며, 별도의 카메라 등과 같은 비젼부(미도시)를 구비하여 상기 비젼부에서 촬영된 영상을 토대로 판별할 수 있다. In this case, the reinforcing material applying unit 140 applies the reinforcing material 240 only on the air pocket 220 into which the inserting material 230 is injected while the applicator 142 linearly moves along the guide part 141. Can supply In this case, the method of distinguishing the air pocket portion 220 into which the insertion material 230 is injected may be a preset state of the injection material 230, and may include a vision unit (not shown) such as a separate camera. It can be determined based on the image taken by the vision unit.
상기와 같이 보강물질(240)을 도포한 후 이송부(180)의 작동에 따라서 보강물질(240)이 도포된 시트(200) 부분이 경화부(150)를 통과할 수 있다. 이때, 경화부(150)는 자외선을 조사하여 보강물질(240)을 경화시킬 수 있다. After applying the reinforcing material 240 as described above, a portion of the sheet 200 to which the reinforcing material 240 is applied may pass through the hardening part 150 according to the operation of the transfer unit 180. At this time, the curing unit 150 may cure the reinforcing material 240 by irradiating ultraviolet light.
또한, 이송부(180)가 계속해서 작동하는 경우 시트(200)는 절단부(160)에 도달하며, 절단부(160)는 시트(200)를 일정한 길이로 절단할 수 있다. In addition, when the transfer unit 180 continues to operate, the sheet 200 reaches the cut unit 160, and the cut unit 160 may cut the sheet 200 to a predetermined length.
