제1도는 본 발명을 설명하기 위한 개략도.1 is a schematic view for explaining the present invention.

제2도는 본 발명을 설명하기 위한 공정별 순서도.2 is a flow chart for each process for explaining the present invention.

제3도는 본 발명에 있어서 손잡이끈이 보강지에 융착된 상태의 확대 단면도.Figure 3 is an enlarged cross-sectional view of the handle strap is fused to the reinforcing paper in the present invention.

제4도는 본 발명이 완성된 쇼핑백의 일부 사시도.4 is a partial perspective view of a shopping bag in which the present invention is completed.

본 발명은 폴리에칠렌 필름을 코팅한 보강지와 보강지 사이에 폴리프로필렌으로된 손잡이끈을 넣어 이송시키면서 공기열로 융착시키는 것으로 특징으로 하는 것으로, 특히 보강지와 보강지사이에 손잡이끈을 넣고 에어 히팅 브로우(air Heating blow) 방식으로 열융착 시키므로 제조공정이 간단하고, 손잡이끈의 접착력을 증대시킴과 동시, 보강지의 재료 절감을 꾀할 수 있도록 하는 쇼핑백에 있어서, 손잡이끈 접착 제조방법에 관한 것이다.The present invention is characterized in that the polypropylene film is coated between the reinforcing paper and the reinforcing paper coated with a polypropylene hand strap while fusion by air heat, particularly between the reinforcing paper and the reinforcing paper put the hand strap between the air heating brow ( The present invention relates to a method for manufacturing hand strap adhesives, in which a manufacturing process is simple due to heat fusion by an air heating blow) method, which increases the adhesive strength of the hand strap and at the same time reduces the material of the reinforcing paper.

일반적으로 종이제의 쇼핑백을 제조함에 있어서는 크라프트지로된 보강지를 이송시키는 도중 접착액을 도포하고, 이에 종이끈을 넣은 다음 대향되는 보강지를 합착시키는 방법으로 손잡이끈 접착을 행하여 왔으나, 이 경우 접착액을 보강지에 도포하여 손잡이끈을 접착시키기 때문에 제조 공정이 복잡하고, 손잡이끈이 보강지와 보강지 사이에 완전하게 밀착되어 접착되지 않으므로 손잡이끈의 보강 강도가 약해지는 결함이 있었고, 이를 해결하기 위해서는 손잡이끈을 고정시켜주는 보강지의 폭을 넓게 하여야만 어느정도 손잡이끈을 보강시켜 줄 수 있기 때문에 보강지의 재료가 많이 드는 문제점이 지적되어 오고 있으며, 특히나 겨울과 같이 실내 온도가 저하될 경우에는 접착액의 접착력이 약화되어 접착 능력이 저하되는 결점이 있어왔다.In general, in the manufacture of shopping bags made of paper, the adhesive has been applied by applying an adhesive liquid during transfer of the reinforcement paper made of kraft paper, putting a paper string into it, and then bonding the opposite reinforcement paper. The manufacturing process is complicated because the hand strap is applied to the reinforcement paper, and the manufacturing process is complicated.Therefore, there was a defect that the hand strap's reinforcement strength was weakened because the hand strap was not completely adhered between the reinforcement paper and the reinforcement paper. It has been pointed out that the material of the reinforcement paper is increased because the handle strap can be reinforced to some extent only when the width of the reinforcing paper fixing the strap is widened. In particular, when the room temperature decreases, such as winter, the adhesive strength of the adhesive liquid There has been a drawback of weakening and deteriorating the adhesive ability.

이와같은 것을 시정하기 위해서는 다음과 같은 방식을 고려하여 볼 수 있다.To correct this, the following methods can be considered.

즉, 폴리에칠렌 필름을 코팅한 보강지와 보강지 사이에 손잡이 끈을 위치시켜 보강지와 손잡이 끈을 동시에 이송시키되, 임의의 위치에 전기 코일에 의한 열판을 위치시켜 보강지를 누르면서 가열케 하므로서, 보강지와 보강지가 융착될 수 있도록 하는것인데 위와같은 방법은 우선, 보강지를 열판으로서 눌러 가열케하므로 가열되는 열판에 의해 보강지가 태워져 로스가 많이 발생되고 뿐만 아니라 심하면 화재 발생도 일어날 수 있는 문제점이 있고, 또한 전력 낭비가 심하며, 보강지의 이송동작을 정지시킴과 동시 열판의 전기 동작을 정지시켰을때 열판에 잔존해 있는 여열에 의해 정지되어 있는 보강지가 망손되는 결함이 지적될 수 있다.That is, by placing the hand strap between the reinforcement paper coated with the polyethylene film and the reinforcement paper to transfer the reinforcement paper and the hand strap at the same time, by placing the hot plate by the electric coil in an arbitrary position to heat while pressing the reinforcement paper, And the reinforcement paper is to be fused to the above method, first, the reinforcement paper is heated by pressing the heating plate as a hot plate, so that the reinforcement paper is burned by the heated hot plate, a lot of loss is generated, as well as a severe fire may occur. In addition, it may be pointed out that defects in which the waste paper is stopped and the reinforcing paper which is stopped by the residual heat remaining on the hot plate when stopping the conveying operation of the reinforcing paper and the electrical operation of the hot plate at the same time may be pointed out.

따라서 본 발명은 상기와 같은 결함 등을 해소하기 위한 방법으로서, 보강지와 보강지 사이의 손잡이끈의 접착을 뜨거운 공기를 불어넣어주는 방식을 채택하여 해결한 것으로 첨부도면에 따라 구체적으로 설명하면 다음과 같다.Therefore, the present invention is solved by adopting a method of blowing the hot air to the adhesion of the handle strap between the reinforcement paper and the reinforcement paper as a method for eliminating the defects as described above in detail according to the accompanying drawings Same as

즉, 제1도에 도시한 바와같이 폴리에칠렌 필름(1)(2')이 이면에 각각 코팅된 보강지(1)(2)와 폴리프로필렌으로된 손잡이끈(3)을 동시에 이송시키는 것에 있어서 가압로울러(4)(5)전방 일측에 열풍기(6)를 설치하여 가압로울러(4)와 (5)사이로 보강지(1)(2)및 손잡이끈(3)을 인입시킴과 동시(제1도 및 제2도 가) 참조) 열풍기(6)로 부터의 열풍으로서 보강지(1)와 보강지(2)이면에 코팅된 폴리에칠렌 필림을 폴리프로필렌으로된 손잡이끈(3)에 열 융착시키는 것이다. (제1도 및 제2도 나) 참조) 이와같이 손잡이끈(3)이 보강지(1)와 보강지(2)사이에 열융착되면서 가압로울러(4)(5)에 의해 압착 되어지므로서, 손잡이끈(3)의 전주면에 밀착되는 부분의 보강지(1)와 보강지(2)가 미세한 공간 없이 완전 밀착되어 손잡이끈(3)을 보강접착시켜 주게된다.(제3도 참조)That is, as shown in FIG. 1, the polyethylene film (1) (2 ') is pressurized at the same time to convey the reinforcement paper (1) (2) and the handle strap (3) made of polypropylene respectively coated on the back side. Installing a hot air fan 6 on one side of the rollers 4 and 5 to draw the reinforcement paper 1 and 2 and the strap 3 between the pressure rollers 4 and 5. And FIG. 2 a)) The hot air from the hot air blower 6 is thermally fused to the polypropylene handrail 3 made of polypropylene film coated on the back surface of the reinforcement paper 1 and the reinforcement paper 2. As shown in FIGS. 1 and 2, the handle strap 3 is compressed by the pressure rollers 4 and 5 while heat-sealed between the reinforcement paper 1 and the reinforcement paper 2. The reinforcement paper 1 and the reinforcement paper 2 of the portion closely contacted with the front circumference of the handle strap 3 are completely in contact with each other without a small space, thereby reinforcing and bonding the handle strap 3 (see FIG. 3).

이후 공지한 바와같이 가압로울러(4)(5)를 통과한 접착된 보강부(7)를 절단칼(8)로서 제1도 및 제2도에 도시한 바와같이 보강부(7)의 중앙부를 절단시키면서 이송시키고(제1도 및 제2도 다) 참조) 이후 임의 길이만큼 보강부(7)를 절단칼(9)로서 절단시켜 이송밸트(10)로 이송시킴과 동시, (제1도 및 제2도 라) 참조) 쇼핑백 본체종이(11)를 이송시키되, 본체종이(11)에 절단된 보강부(7) 2개를 재치하면서 접착하여 이송시킨다. (제1도 및 제2도 마) 참조) 이후본체종이(11)를 재단하여 쇼팽백(12)을 완성시키게 되는데, 이의 동작은 통상적인 방법이므로 생략한다. 도면중 , ㄱ, ㄷ, ㅁ은 보강지(1) 이송 로울러, ㄴ, ㄹ, ㅂ은 보강지(2) 이송 로울러, ㅅ, ㅇ은 손잡이끈(3) 이송로울러, ㅈ, ㅊ, ㅋ은 본체종이(11) 이송로울러, ㅌ은 보강지(1)(2) 송출드럼, ㅍ은 손잡이끈 송출드럼, ㅎ은 본체종이 송출드럼이다.Then, as is known, the bonded reinforcement portion 7 that has passed through the pressure rollers 4 and 5 is used as a cutting knife 8, as shown in FIGS. 1 and 2, as shown in FIGS. While cutting (see FIGS. 1 and 2) and then cutting the reinforcement part 7 with the cutting knife 9 by an arbitrary length and conveying it to the conveying belt 10. See FIG. 2D)) The shopping bag body paper 11 is transported, and the two reinforcing parts 7 cut on the body paper 11 are bonded and transported. (See Figs. 1 and 2) E) After cutting the body paper 11, the chopin bag 12 is completed, and the operation thereof is omitted since it is a conventional method. In the drawing, a, c, k are reinforcement paper (1) feed rollers, b, d, thin reinforcement paper (2) feed rollers, m, k handlebars (3) feed rollers, k, k, k Paper (11) conveying roller, thin reinforcing paper (1) (2) delivery drum, p-handle drum delivery drum, the main body paper delivery drum.

이상과 같이 보강지(1)(2)이면의 폴리에칠렌 필림과 손잡이끈(3)의 폴리프로필렌을 열풍으로서 열융착 시키므로서, 접착시키는 제조공정이 간단하고, 생산성이 높을뿐 아니라 접착부위의 강도가 강하므로 보강지(1)(2) 각각의 폭을 줄여도 손잡이끈(3)의 인장강도에는 영향을 미칠바 없어 보강지(1)(2)의 재료 절감을 꾀할 수 있게 되는 것이다.As described above, the heat-sealing of the polyethylene film on the back surface of the reinforcement paper (1) and the polypropylene of the handle strap (3) as hot air makes the manufacturing process of bonding simple, high productivity, and high strength of the bonding site. Since it is strong, even if the width of each of the reinforcing paper (1) (2) is reduced does not affect the tensile strength of the handle strap (3) will be able to reduce the material of the reinforcing paper (1) (2).

그런데 상기 제조 공정에 있어서, 열풍기(6)는 실린더(6')에 의하여 제1도에서 보면 좌, 우 이동 자재토록되어 있으며, 공기는 송풍기(13)로서 열풍기(6)측으로 송풍시키고 있는데, 후술하는 예열열풍기(14)(15)도 송풍기(13)에 연결시키도록 되어 있다.In the manufacturing process, the hot air blower 6 is moved left and right by the cylinder 6 'as shown in FIG. 1, and the air is blown to the hot air blower 6 as the blower 13, which will be described later. The preheater fans 14 and 15 are also connected to the blower 13.

한편, 보강지(1)와 (2)및 손잡이끈(3)이 가압 로울러(4)(5)사이로 인입되기 직전에 상기 열풍기(6)를 실린더(6')에 의하여 제1도에 도시한 상태에서 우측으로 즉, 가압로울러(4)(5) 일측 전방에 열풍기(6)를 위치시키되, 가압로울러(4)(5)와 열풍기(6)의 일측 끝단(열풍이 나오는 부분)과의 거리는 약 6-7mm로 하는 것이 바람직하다.On the other hand, just before the reinforcing paper 1 and 2 and the hand strap 3 are drawn between the pressure rollers 4 and 5, the hot air fan 6 is shown in FIG. 1 by the cylinder 6 '. In the state to the right, that is, the hot air blower 6 is positioned in front of one side of the pressure roller 4, 5, and the distance between the pressure roller 4, 5 and one end of the hot air blower 6 is the distance from which the hot air comes out. It is preferable to set it as about 6-7 mm.

왜냐하면, 보강지(1)과 (2)이면에 코팅된 폴리에칠렌 필림에 강한 열풍이 닿게되면 전술한 열융착에 나쁜영향이 미치게 되므로 약 6-7mm의 간격을 둔 상태에서 보강지(1)와 (2)의 이면에 열풍을 가하는 것이 바람직하다. 그리고, 모든 동작이 정지될 때에는 열풍기(6)는 실린더(6')에 의하여 제1도 도시한 상태에서 좌측으로 이동시켜 여열에 의해 보강지(1)(2)가 망손되는 것을 방지한다.Because, when the strong hot air is applied to the polyethylene film coated on the backing of the reinforcing paper (1) and (2) will adversely affect the above-mentioned heat welding, the reinforcing paper (1) and ( It is preferable to apply hot air to the back side of 2). Then, when all the operations are stopped, the hot air blower 6 moves to the left in the state shown in FIG. 1 by the cylinder 6 'to prevent the reinforcement paper 1 and 2 from being damaged by the heat.

만약 실내 온도가 낮아 열풍기(6)로서 열융착 능력이 저하될 경우에는 가압로울러(4)(5) 일측 상, 하의 보강지(1)(2)전방에 설치하는 예열 열풍기(14)(15)로서, 보강지(1)(2)이면에 코팅된 폴리에칠렌 필림을 예열시키면서 가압로울러(4)(5)측으로 보강지(1)(2)를 이송시킨다.If the heat fusion capacity of the hot air blower 6 is lowered due to a low indoor temperature, the preheating hot air blower 14 and 15 installed in front of the reinforcement paper 1 and 2 on one side of the pressure roller 4 and 5 may be lowered. As a result, the reinforcement papers 1 and 2 are transferred to the pressure rollers 4 and 5 while preheating the polyethylene film coated on the back surface of the reinforcement papers 1 and 2.

따라서 폴리에칠렌 필림이 예열되어진 상태에서 열풍기(6)에 의해 보강지(1)와 (2)및 손잡이끈(3)을 열융착시키게 되므로서 실내온도가 낮은 겨울에도 열융착 능력을 저하시키지 않게 되는 것이다.Therefore, the heat-sealing of the reinforcement paper (1) and (2) and the handle strap (3) by the heat blower (6) in the pre-heated state of the polyethylene film will not lower the heat-sealing ability even in the low winter temperature .

상기의 예열 열풍기(14)(15)도 열풍기(6)과 마찬가지로 실린더(14')(15')에 의해 이동 자재토록 되어 있다.The preheating hot air fans 14 and 15 are also moved by the cylinders 14 'and 15' similarly to the hot air fans 6.

이상과 같이 본 발명은 폴리에칠렌 필림이 코팅된 보강지와 보강지 및 폴리프로필렌으로된 손잡이끈을 열풍기로 열융착시키므로서, 접착 부위의 밀착도가 높고, 따라서 접착 강도가 강하여 손잡이끈을 보강하는 보강지의 재료 절감을 꾀할 수 있으며, 겨울과 같이 실내온도가 낮은 경우에는 별도의 예열 열풍기로서 보강지를 예열시켜 열융착케하는 등 그 제조공정이 간단하고, 생산 능률이 높은 특징이 있다.As described above, the present invention is to heat-bond the reinforcement paper coated with polyethylene film and the reinforcement paper and the polypropylene grip with a hot air blower, so that the adhesion of the adhesive site is high, and thus the adhesive strength is strong, thereby reinforcing the handle strap. Material savings can be achieved, and if the room temperature is low, such as winter, the manufacturing process is simple and the production efficiency is high, such as preheating the reinforcement paper with a separate preheating hot air fan to heat fusion.
