Description

육수용 PLA부직포 주머니 제조방법 및 이에 의해 제조된 육수용 PLA부직포 주머니{Manufacturing method of PLA non-woven fabric pouch for dashi and PLA non-woven fabric pouch for dashi} PLA non-woven fabric pouch for broth, and PLA non-woven fabric pouch for dashi and PLA non-woven fabric pouch for dashi manufactured by the same

본 발명은 육수용 PLA부직포 주머니 제조방법 및 이에 의해 제조된 육수용 PLA부직포 주머니에 관한 것으로서, 보다 상세하게는 단부를 초음파융착방식으로 융착함으로써 불량률이 낮고 생산성은 높은 새로운 방식의 육수용 PLA부직포 주머니제조방법 및 이에 의해 제조되어 환경친화적이며 내구성도 우수하고 코스트로 저렴하며 새로운 구성의 육수용 PLA부직포 주머니에 관한 것이다.The present invention relates to a method for manufacturing a PLA non-woven fabric bag for broth and a PLA non-woven fabric bag for broth produced thereby, more specifically, a new method of PLA non-woven fabric bag for broth with a low defect rate and high productivity by welding an end by an ultrasonic welding method. It relates to a manufacturing method and an environmentally friendly, durable, cost-effective, and non-woven PLA non-woven fabric pouch produced by the method.

일반적으로 찌개나 국 등을 조리할 때에는 풍미를 좋게 하기 위해 멸치, 다시마, 새우, 야채 등을 사용하여 미리 육수(다시)를 만들어서 사용한다.In general, when cooking stew or soup, anchovy, kelp, shrimp, vegetables, etc. are used to make broth (again) in advance to improve flavor.

그런데 육수를 만들 때에는 육수 재료를 간편하게 건져내기 위해 육수재료를 스텐레스스틸제 타공망으로 만든 거름통에 넣고 끓이는데, 거름통을 사용하는 경우에는 거름통에 담긴 육수재료를 털어내고 거름통을 일일이 세척하여야 하는 번거로움이 있을 뿐만 아니라 거름통의 타공을 통해 육수재료의 부스러기가 빠져나와서 육수가 지저분해지는 단점을 가진다. 따라서 최근에는 부직포로 된 일회용 육수 주머니가 시판되고 있는데, 이러한 일회용 육수 주머니를 사용하는 경우에는 주머니에 육수재료를 담아서 끓인 다음, 주머니를 건져내고 육수재료를 털어내고 주머니를 그냥 버리면 되므로 주머니를 세척하여야 하는 번거로움이 없기는 하나, 부직포가 PE나 PP 등의 합성섬유를 제조되어 썩지 않는 특성을 가지므로 폐기 후에 환경오염을 유발한다.When making broth, however, the broth is placed in a manure container made of stainless steel perforation to boil the broth material easily, and when using the manure, the hassle of removing the broth material contained in the manure and washing the manure is required. In addition, there is a disadvantage in that the broth of the broth comes out through the perforation of the manure, and the broth becomes messy. Therefore, recently, disposable broth bags made of non-woven fabrics are commercially available. In the case of using such disposable broth bags, it is necessary to wash the pouch, since the boiled material is boiled in the pouch, then the pouch is removed, the broth material is shaken off and the bag is discarded. Although there is no hassle, non-woven fabrics are made of synthetic fibers such as PE or PP and have non-corrosive properties, causing environmental pollution after disposal.

한편, 이러한 부직포로 된 일회용 육수 주머니의 제조시 부직포를 주머니 형태로 만들기 위해 부직포를 원하는 형태 및 크기로 절단하고 겹친 다음, 단부를 열융착기를 이용하여 융착시키는데, 융착온도가 높으면 융착과정에서 부직포가 과도하게 용융되어 주머니에 구멍이 뚫려서 불향이 발생되고, 반대로 융착온도가 낮으면 단부가 제대로 융착되지 않아 불량이 발생된다.On the other hand, when manufacturing the disposable broth pouch made of such a non-woven fabric, the non-woven fabric is cut into a desired shape and size and overlapped to make a non-woven fabric into a pouch shape, and then the ends are fused using a heat fusion machine. It melts excessively, and a hole is formed in the bag, causing incense. On the contrary, when the welding temperature is low, the end is not properly fused, resulting in defects.

따라서 사용하는 부직포의 물성에 따라 융착온도를 미세하게 조절할 필요가 있는데, 부직포가 상당히 얇기 때문에 불량이 발생되도록 융착온도를 미세하게 조절하여 주머니를 만들기가 쉽지 않다.Therefore, it is necessary to finely adjust the fusing temperature according to the physical properties of the nonwoven fabric used, and it is not easy to make a pouch by finely adjusting the fusing temperature to cause defects because the nonwoven fabric is quite thin.

본 발명은 상기와 같은 문제점에 착안하여 제안된 것으로서, PLA부직포를 재단하고 단부를 초음파 융착하여 자루형태로 만듦으로써 불량률이 낮고 생산성은 높은 새로운 방식의 육수용 PLA부직포 주머니제조방법 및 이에 의해 제조되어 생분해성을 가져서 환경친화적이며, 내구성도 우수하고 코스트로 저렴한 새로운 구성의 육수용 PLA부직포 주머니를 제공하는 것이다.The present invention has been proposed in view of the above problems, by cutting the PLA non-woven fabric and ultrasonically welding the ends to form a bag, the defect rate is low and the productivity is high.

이상과 같은 구성을 가지는 본 발명은 다음과 같은 효과를 가진다.The present invention having the above configuration has the following effects.

첫째, PLA부직포를 사용하기 때문에, 일회용품에도 불구하고 환경친화적인 육수용 주머니를 만들 수 있다.First, because it uses PLA non-woven fabric, it is possible to make environmentally friendly broth pouch despite disposable products.

둘째, 초음파 융착하여 주머니형태로 접합시키기 때문에, 열융착방식으로 접합시키는 경우에 비해 생산성이 우수하며, 사용하는 PLA부직포의 물성에 따라 진동에너지의 진폭을 미세하게 조절함으로써 융착시 융착부위에 구멍이 발생되는 등의 불량발생원인이 해소되기 때문에, 불량률이 감소된다. 따라서 불량률이 감소되고, 생산성이 향상되므로 제품의 코스트가 저하된다.Second, because it is ultrasonically welded and bonded in the form of a bag, it has better productivity than when it is joined by a heat-sealed method, and by finely adjusting the amplitude of vibration energy according to the physical properties of the PLA non-woven fabric, holes are formed in the fusion area during fusion. Since the cause of defects such as occurrence is eliminated, the defect rate is reduced. Therefore, the defect rate is reduced and productivity is improved, so the cost of the product is lowered.

이하에서, 본 발명의 좀 더 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail as follows.

도 1은 본 발명의 제1실시예에 의해 제조된 육수 주머니의 정면도이다. 본 발명은 상부가 개방된 자루형태이 주머니본체(100)와, 주머니본체(100)의 좌우 양단 상측에 한 쌍의 묶음용 끈(200)이 결합된 구성을 가지는 육수용 주머니를 제조하는 방법에 관한 것으로서, 다음과 같은 공정으로 이루어진다. 1 is a front view of a broth bag prepared by the first embodiment of the present invention. The present invention relates to a method of manufacturing a bag for a broth having a configuration in which a bag form having an open top has a configuration in which the bag body 100 and a pair of bundle strings 200 are coupled to the upper left and right ends of the bag body 100. As it is, it consists of the following steps.

1) PLA부직포를 재단하는 과정1) PLA non-woven fabric cutting process

PLA(Poly lactic acid)부직포는 공지된 것을 사용하는데, PLA부직포를 세로로 긴 직사각형태를 갖도록 재단하여 주머니 원단을 만든다.PLA (Poly lactic acid) non-woven fabrics are known, and the PLA non-woven fabric is cut to have a vertically long rectangular shape to make a pouch fabric.

2) 묶음용 끈을 만드는 과정2) The process of making a string for bundling

상기 주머니 원단을 만든 PLA부직포와 동일한 종류의 PLA부직포를 길이가 긴 끈형태로 재단하여 한 쌍의 묶음용 끈(200)을 만든다. 이 묶음용 끈은 후술하는 바와 같이, 육수 제조시에 육수재료가 육수 주머니 외부로 유출되지 않도록 주머니본체의 상단부를 묶기 위한 것이다. A PLA nonwoven fabric of the same type as the PLA fabric made of the pouch fabric is cut into a long string shape to make a pair of strings 200 for bundling. This bundling strap is for binding the upper end of the bag body so that the broth material does not flow out of the broth bag during the preparation of the broth, as will be described later.

3) 묶음용 끈을 배치하는 과정3) The process of arranging the string for the bundle

상기 묶음용 끈들을 일단부가 상기 주머니 원단의 좌우 양단 상측부위에 각각 겹쳐지도록 묶음용 끈들을 배치한다.The strings for bundling are arranged so that one end of the bundling strings overlaps the upper and lower ends of the pocket fabric, respectively.

4) 주머니 원단을 접는 과정4) The process of folding the pocket fabric

상기 주머니 원단의 하반부를 상향으로 접어서 주머니 원단을 상하로 중첩시킨다. 이와 같이 하면, 상기 묶음용 끈의 일단부는 상하로 중첩된 주머니 원단 사이에 위치되고, 주머니 원단의 상반부와 하반부가 완성된 주머니본체의 전면 및 배면을 이루게 된다. The bottom half of the pocket fabric is folded upward to overlap the pocket fabric up and down. In this way, one end of the string for bundling is positioned between the pocket fabrics overlapped up and down, and the upper and lower parts of the pocket fabric form the front and rear surfaces of the completed pocket body.

5) 주머니 원단의 좌우 양측 단부를 초음파 융착시키는 과정5) The process of ultrasonic welding the left and right ends of the pocket fabric

상기 과정에서 상하로 중첩된 주머니 원단의 좌우 양측단부를 초음파 융착시킨다. 이 과정은 초음파 융착기를 사용하여 행해지는데, 초음파 융착기는 초음파의 진동을 이용하여 피가공물을 융착하는 것으로서, 발진기(generator)를 통하여 20~40kHz(1sec)의 전기적 에너지를 발생시키고, 전기적 에너지를 컨버터(진동자)와 부스터(메인혼)를 통해 기계적인 진동에너지로 변환한 후 공구혼을 통하여 피가공물에 전달시켜서 피가공물을 융착시키는 것으로서, 진동에너지(초음파)가 피가공물에 전달되면 순간적인 강력한 진동에 의한 마찰열이 발생되어 피가공물이 융착된다. 접합면이 용착된다. In the above process, the left and right sides of the pocket fabric overlapped up and down are ultrasonically fused. This process is performed using an ultrasonic fusion machine, which fusions a workpiece using ultrasonic vibration, generates electrical energy of 20 to 40 kHz (1 sec) through a generator, and converts electrical energy into it. (Vibrator) and booster (main horn) are converted to mechanical vibration energy and then transferred to the workpiece through the tool horn to fuse the workpiece, and when vibration energy (ultrasound) is transmitted to the workpiece, instantaneous powerful vibration Heat generated by friction is generated and the workpiece is fused. The joint surface is welded.

이러한 초음파 융착과정에서는 사용되는 PLA부직포의 융점, 두께 등의 물성에 따라 진동에너지의 진폭을 미세하게 조절하여, 융착부위가 과도하게 용융되어 구멍이 생기지 않으면서도 효과적으로 잘 융착되도록 한다. In this ultrasonic welding process, the amplitude of vibration energy is finely adjusted according to the physical properties such as the melting point and thickness of the PLA non-woven fabric used, so that the fusion site is melted excessively and effectively fuses without creating a hole.

본 과정에서 초음파 융착방법을 사용하지 않고 열융착을 통해 PLA부직포, 즉, 주머니 원단의 좌우 양단부를 부착시킬 수도 있을 것이나, 열융착시에는 제품 불량을 없애기 위해 PLA부직포의 물성에 따라 열융착기의 열판의 온도를 미세하게 조절하여야 하는데, 열융착기의 열판 온도 조절에 비해 초음파 융착기의 진동에너지의 진폭을 한층 더 미세하게 조절하기가 용이하므로 초음파 융착방법을 사용하는 것이 열융착방법을 사용하는 것 보다 제품 불량을 줄일 수 있다. In this process, it is possible to attach the PLA nonwoven fabric, that is, the left and right ends of the pocket fabric through heat fusion without using the ultrasonic fusion method, but in order to eliminate product defects during heat fusion, the hot plate of the heat fusion machine according to the properties of the PLA nonwoven fabric It is necessary to fine-adjust the temperature of the product, so it is easier to fine-tune the amplitude of the vibration energy of the ultrasonic fusion machine compared to the temperature control of the heat plate of the heat fusion machine, so it is easier to use the ultrasonic fusion method than the heat fusion method. Reduce defects.

뿐만 아니라, 초음파융착은 강력한 진동에너지에 피가공물에 순간적으로 고온의 마찰열이 발생되어 융착이 이루어지는 것이므로 1초 이하의 상당히 짧은 시간에 융착이 이루어지기 때문에, 열융착에 비해 생산성도 높은 장점을 가진다.In addition, since ultrasonic welding is a strong vibrational energy, the friction is generated by generating high-temperature frictional heat instantaneously in a workpiece, and thus, welding is performed in a very short time of less than 1 second, and thus productivity is higher than thermal welding.

특히, 초음파 융착시에는 초음파 진동에 의해 피가공물의 융착면이 용융되어 젖음상태가 된 상태에서 계속적인 진동이 가해지면 피가공물의 중합체에서 결합하고 남은 가원자들 사이에 분자결합이 이루어지기 때문에 단순히 표면이 용융되어 융착이 이루어지는 열융착에 비해 융착강도가 높은 장점을 가진다. In particular, during ultrasonic welding, if the welding surface is melted by the ultrasonic vibration and the continuous vibration is applied in the wet state, molecular bonding is performed between the remaining atoms and the polymer bound to the workpiece. Compared to thermal fusion, where the surface is melted and fused, the fusion strength is high.

이와 같이 상하로 중첩되게 접은 주머니 원단의 좌우 양단부를 융착시키면, 상부가 개방된 주머니본체(100)가 형성되면서 주머니본체(100)에 묶음용 끈(200)이 결합되어 상부가 개방된 자루형태의 육수 주머니가 형성된다.When the left and right ends of the pocket fabric folded so as to overlap vertically as described above are fused, the strap body 200 is coupled to the pocket body 100 while the upper portion is formed, so that the upper bag is opened and the upper bag is opened. A broth bag is formed.

이와 같은 방법으로 제조되는 육수 주머니는 PLA부직포로 이루어지므로 생분해성을 가지므로 환경친화적인 장점을 가지는 것은 물론이며, 초음파 융착으로 단부를 융착하여 제조되기 때문에 열융착방법으로 융착시키는 것에 비해 생산성이 높고 불량률도 낮으며, 융착된 부분의 융착강도가 우수하여 사용시 융착된 부분이 터질 우려도 없다. The broth pouch produced in this way is made of PLA non-woven fabric, so it has biodegradability, so it has an environmentally friendly advantage, and it is manufactured by welding the ends by ultrasonic fusion, so it has higher productivity than fusion by heat fusion. The defect rate is also low, and the fusion strength of the fused portion is excellent, so there is no fear that the fused portion will burst when used.

따라서 본 발명에 의한 방법을 사용하면 생분해성을 가져서 환경친화적이고 품질이 우수한 육수 주머니를 저렴한 코스트도 제조할 수 있다.Therefore, if the method according to the present invention is used, it is possible to manufacture an environmentally friendly and excellent quality broth pouch at low cost by having biodegradability.

이하에서는 본 발명의 다른 실시예를 설명하되, 전술한 실시예와 동일한 구성 및 효과에 대해서는 설명을 생략한다.Hereinafter, another embodiment of the present invention will be described, but description of the same configuration and effect as the above-described embodiment will be omitted.

도 2와 3은 본 발명의 제3실시예를 보인 도면이다. 본 실시예에서는 도 2에 도시된 바와 같이, 묶음용 끈(200)이 가로로 긴 묶음부(210)와, 묶음부(210)의 일단부에서 세로로 길게 일체로 연장되는 세로겹침부(220)로 이루어지도록, PLA부직포를 재단하여 묶음용 끈(200)을 만든다. 2 and 3 are views showing a third embodiment of the present invention. In this embodiment, as shown in FIG. 2, the string 200 for bundling is a horizontally long bundling part 210 and a vertically overlapping part 220 extending vertically and integrally from one end of the bundling part 210 vertically. ), Cut the PLA non-woven fabric to make a string 200 for bundling.

따라서 본 실시예에 의한 묶음용 끈(200)이 묶음부(210)의 일단부에 세로겹침부(220)가 세로로 길게 일체로 연장되어 전체적으로 ㄱ형상을 가지는데, 세로겹침부(220)는 주머니 원단의 세로길이의 1/2에 대응되는 길이를 갖는다.Therefore, the string 200 for bundling according to this embodiment extends vertically and integrally at one end of the bundling unit 210 vertically and has a shape as a whole. It has a length corresponding to 1/2 of the length of the pocket fabric.

본 실시예에서는 이러한 묶음용 끈(200)의 세로겹침부(220)가 주머니 원단의 좌우 양단부에 겹쳐지도록 배치하고, 이 상태에서 주머니 원단의 하반부를 상향으로 접어 올리는데, 이와 같이 하면 묶음용 끈(200)의 세로겹침부(220)가 주머니 원단의 상반부와 하반부 사이에 위치되어 묶음용 끈(200)의 세로겹침부(220)와 주머니 원단의 상반부와 하반부가 겹쳐진 부위가 3겹을 이루게 된다. 그리고 주머니 원단의 좌우 양단부를 초음파 융착시키면 도 3에 도시된 바와 같이, 묶음용 끈(200)의 세로겹침부(220)가 주머니 원단의 좌우 양단부와 겹쳐진 상태로 융착되어 결합된다. In this embodiment, the vertical overlap portion 220 of the string 200 for bundling is arranged to overlap the left and right ends of the pocket fabric, and the lower half of the pocket fabric is folded upward in this state. The vertical overlapping portion 220 of 200) is located between the upper and lower portions of the pocket fabric, and the overlapping portion of the vertical overlapping portion 220 of the strap 200 and the upper and lower portions of the pocket fabric forms three layers. And if the left and right ends of the pocket fabric are ultrasonically fused, as shown in FIG. 3, the vertical overlap portion 220 of the string 200 for bundling is fused and combined with the left and right ends of the pocket fabric.

본 실시예에서는 묶음용 끈(200)의 세로겹침부(210)가 주머니본체(100)의 좌우 양단부에 결합되기 때문에, 묶음용 끈(200)과 주머니본체(100)가 상대적으로 넓은 면적으로 융착되어 묶음용 끈(100)과 주머니본체(100)의 결합이 한층 견고하게 이루어진다. 또한, 전술한 실시예에서는 묶음용 끈(200)의 일단부가 주머니 원단의 좌우 양단부에 겹쳐지는 부분만 3겹이고 다른 부분은 2겹인데 반해, 본 실시예에서는 세로겹침부(220)가 주머니 원단의 상반부 및 하반부의 길이와 동일한 길이를 가지기 때문에 초음파 융착부위가 전체적으로 3겹의 두께를 가지므로, 초음파 융착부위 전체가 다른 부위에 비해 상대적으로 두꺼운 두께를 가져서 보강된다. 따라서 융착상태가 견고하기 때문에, 육수 주머니에 육수재료를 넣기 위해 주머니본체(100)를 벌리더라도 초음파 융착부위가 쉽게 터지지 않는 장점을 가진다.In this embodiment, since the vertical overlap portion 210 of the string 200 for bundling is coupled to both left and right ends of the pocket body 100, the string 200 for bundling and the pocket body 100 are fused with a relatively large area. The combination of the string 100 for the bundle and the pocket body 100 is made more robust. In addition, in the above-described embodiment, only one portion of the one end portion of the string 200 for the bundle overlaps the left and right ends of the pocket fabric and the other portion is two layers, whereas in the present embodiment, the vertical overlap portion 220 is the pocket fabric. Since it has the same length as the upper half and the lower half of the ultrasonic fusion site has a three-ply thickness as a whole, the entire ultrasonic fusion site has a relatively thick thickness compared to other parts to be reinforced. Therefore, since the fusion state is solid, even if the bag body 100 is opened to put the broth material into the broth bag, the ultrasonic fusion site does not easily break.

도 4와 도 5는 본 발명의 제3실시예를 보인 도면이다. 본 실시예에서는 도 4에 도시된 바와 같이, 묶음용 끈(200)이 묶음부(210)와 세로겹침부(220)를 포함하되, 묶음부(210)와 세로겹침부(220) 사이에는 묶음부(210)와 세로겹침부(220)의 연결부위를 넓게 확장시키기 코너확장부(230)가 형성된다. 본 실시예에서는 이 코너확장부(230)가 삼각형상으로 형성된 것으로 예시되었다.4 and 5 are views showing a third embodiment of the present invention. In this embodiment, as shown in Figure 4, the string for bundling 200 includes a bundling portion 210 and a vertical overlapping portion 220, but is bundled between the bundling portion 210 and the vertically overlapping portion 220 A corner extension portion 230 is formed to widen the connection portion between the portion 210 and the vertical overlap portion 220. In this embodiment, it has been illustrated that the corner extension 230 is formed in a triangular shape.

이와 같이 묶음용 끈(200)의 묶음부(210)와 세로겹침부(220) 사이에 코너확장부(230)가 형성되면, 묶음용 끈(200)으로 주머니본체(100)의 상단부를 묶을 때 사용자가 묶음용 끈(200)을 비교적 큰 힘으로 잡아당기더라도 묶음부(210)와 세로겹침부(220)의 연결부위에 응력이 집중되어 묶음부(210)의 단부가 세로겹침부(220)에서 끊어지는 것이 방지된다. 따라서 한층 더 견고한 육수용 주머니를 만들 수 있다.When the corner extension portion 230 is formed between the bundle portion 210 and the vertical overlap portion 220 of the bundle string 200, when tying the upper end of the pocket body 100 with the bundle string 200 Even if the user pulls the string 200 for the bundle with a relatively large force, stress is concentrated on the connection portion between the bundle 210 and the vertical overlap 220, so that the end of the bundle 210 is vertically overlapped 220 It is prevented from being cut off. Therefore, it is possible to make a more robust broth pouch.
