Description

포장장치에서의 시일장치{SEALING DEVICE FOR PACKAGING APPARATUS}SEALING DEVICE FOR PACKAGING APPARATUS}

이 종류의 포장장치에서의 시일장치는 예를 들어 소정 간격을 두고 피포장물이 수납된 통형상 필름을 간헐 반송하고 상기 필름의 상하에 협착체를 마주 설치하며, 필름 반송을 일단 정지한 상태에서 필름의 피포장물 사이의 위치를 필름 바깥쪽에서 상기 협착체로 협착하며, 상기 협착체의 선단표면의 히터열에 의해 필름을 용착하여 필름의 피포장물 사이의 위치를 차례로 구획 시일하고 예를 들어 또한 상기 히트시일 위치의 중간부를 절단하여, 간헐반송함으로써 피포장물을 넣는 포장 봉지가 차례로 반송되도록 구성하고 있다.The sealing device in this type of packaging device intermittently conveys, for example, a cylindrical film containing a packaged object at predetermined intervals, faces a constriction body on the upper and lower sides of the film, and stops the film conveyance once the film is stopped. The position between the packaged objects of the film is confined from the outside of the film to the constrictor, and the film is welded by the heater heat of the front end surface of the constrictor to partition and seal the position between the packaged material of the film in turn, for example, the heat seal position. The intermediate | middle part of this is cut | disconnected, and it is comprised so that the packaging bag which puts a to-be packaged object may be conveyed one by one by intermittent conveyance.

그러나, 설령 피포장물 간격이 항상 일정해지도록 하여, 항상 필름의 피포장물과 피포장물 중간 위치를 확실하게 협착하여 히트시일하도록 제어할 수 있어도, 상기 히트시일 위치에 피포장물의 부스러기 등이 있으면, 히트시일 불량을 초래할 우려가 있다.However, even if the interval between the packages to be kept constant is always controlled so as to reliably squeeze the package and the package intermediate positions of the film at all times, if there is debris or the like at the heat seal position, There is a fear of causing a seal failure.

즉, 예를 들어 피포장물이 버섯과 같은 부스러기가 나오기 쉬운 것이면, 필름 내에 버섯의 가는 조각이나 버섯의 밑뿌리 부분의 부스러기나 토양 등이 나오는 경우가 있고, 협착체에 의해 설령 버섯 자체를 협착하지 않아도 이와 같은 부스러기를 필름과 함께 맞물어 협착하여 히트시일을 실시하면 필름 끼리의 열용착이 불충분해지고, 제봉후 용착한 곳이 갈라지거나 부분적으로 전혀 용착하지 않는 곳이 발생하는 등의 시일 불량을 초래할 우려가 있다.That is, for example, if the packaged material tends to come out of debris such as mushrooms, fine pieces of mushrooms or debris or soil of the root part of the mushrooms may appear in the film. Even if such a debris is held together with the film to be squeezed and subjected to heat sealing, the heat welding between the films becomes insufficient, resulting in a seal failure such as cracking of the welded areas after sealing or partial unwelding. There is concern.

또한, 상기 히트시일 부분은 절단위치가 되기도 하며, 이 부분에 부스러기가 끼면 절단불량이나 절단칼의 파손이나 마모를 가속시키게 되기도 한다.In addition, the heat seal portion may be in a cutting position, and if debris is caught in this portion, it may accelerate cutting defects or breakage or wear of the cutting knife.

본 발명은, 이와 같은 종래의 시일장치를 개량하고 상술한 바와 같은 맞물려 들어가는 문제를 해결할 수 있는 매우 획기적인 포장장치에서의 시일장치를 제공하는 것을 목적으로 하고 있다.An object of the present invention is to provide a sealing device in a very innovative packaging device that can improve such a conventional sealing device and solve the above-mentioned engagement problem.

본 발명은 소정 간격을 두고 피포장물이 수납된 필름의 피포장물 사이의 위치를 필름 바깥쪽으로부터 협착하여(nipping) 필름을 히트시일하는 포장장치에서의 시일장치에 관한 것이다.The present invention relates to a sealing apparatus in a packaging apparatus that heat seals a film by nipping the position between the packages of the film in which the packages are stored at a predetermined interval from the outside of the film.

다음에 본 발명의 요지가 되는 종시일 장치(6)의 구성에 대해서 도 8∼도 12를 주체로 하여 설명한다.Next, the structure of the longitudinal seal apparatus 6 which becomes the summary of this invention is demonstrated mainly with FIGS. 8-12.

본 실시예에서는 소정 간격을 두고 피포장물(3)이 수납된 통 형상의 필름(1)의 상하에 아래쪽 협착체(21)와 위쪽 협착체(22)를 설치하고 상기 협착체(21,22)를 상하방향으로 서로 접근 이동시키며, 소정 위치에 반송정지시킨 필름(1)의 피포장물(3)과 피포장물(3)의 중간위치를 바깥쪽에서부터 협착하고, 상기 협착체(21,22)의 선단표면의 히터열에 의해 필름 끼리를 용착하여 필름(1)의 피포장물(3) 간을 구획시일하고 또한 절단장치(7)에 의해 상기 히트시일위치(P)의 중간부를 절단하여 반송측의 피포장물(3)을 넣은 포장봉지(12)를 잘라 내어 반출하는 포장장치에서의 시일장치에 본 발명을 적용한 것이다.In the present embodiment, the lower constrictor 21 and the upper constrictor 22 are provided above and below the cylindrical film 1 in which the package 3 is accommodated at predetermined intervals. Are moved closer to each other in the up and down direction, and the intermediate position of the packaged object 3 and the packaged object 3 of the film 1 conveyed and stopped at a predetermined position is narrowed from the outside, and the The films are welded to each other by the heat of the heater on the front end surface, and the seals are partitioned between the packings 3 of the film 1, and the cutting device 7 cuts the intermediate portion of the heat seal position P, thereby removing the film on the conveying side. This invention is applied to the sealing apparatus in the packaging apparatus which cuts out the packaging bag 12 which put the package 3, and carries out.

이 경우, 본 실시예에서의 상기 아래쪽 협착체(21)에는 필름(1)의 폭방향을 따르고, 또 필름(1)의 전송방향에 대해 전후방향(길이방향)으로 분단하는 공간부로 이루어진 슬릿부(23)가 설치되고, 이 슬릿부(23)에 의해 상기 아래쪽 협착체(21)가 슬릿부(23)를 통해 2분할로 분단되어 형성되고, 이 분단에 의해 슬릿부(23)를 경계로 하여 그 전후위치에 필름(1)의 폭방향을 따라 2열의 히트시일이 실시되도록 구성되어 있다.In this case, in the lower constriction body 21 according to the present embodiment, a slit portion formed of a space portion along the width direction of the film 1 and divided in the front-rear direction (length direction) with respect to the transfer direction of the film 1. (23) is provided, and the lower constriction body 21 is divided into two parts through the slit part 23 by this slit part 23, and this division makes the slit part 23 boundary. And two rows of heat seals are provided at the front and rear positions along the width direction of the film 1.

상기 슬릿부(23)에 의한 아래쪽 협착체(23)의 공간부분에는 판 형상체로 구성한 필름 밀어 올림체(20)를 상하 진퇴 자유롭게 설치하고 있다.In the space part of the lower constriction body 23 by the said slit part 23, the film pushing up body 20 comprised from the plate-shaped body is provided freely up and down.

또한, 상기 필름 밀어 올림체(20)를 밀어 올림 구동하는 상하 진퇴구동기구(24)의 구체적인 구조에 대해서는 후술하지만, 본 실시예에서는 상하의 협착체(21·22)가 협착하기 전, 즉 아래쪽 협착체(21)가 상승하여 히트시일을 위한 협착 이동을 실시하기 전에, 우선 필름 밀어 올림체(20)가 상하 진퇴구동기구(24)에 의해 상승하고, 상기 필름 밀어 올림체(20)의 선단 가장자리가 통형상의 필름(1)을 아래쪽으로부터 밀어 올리도록 구성하고 있다.In addition, although the specific structure of the up-and-down forward / reduction drive mechanism 24 which pushes up the said film pushing up body 20 is mentioned later, in this embodiment, before the upper and lower limiting bodies 21 and 22 are narrowed, ie, the lowering narrowing, Before the sieve 21 is raised to perform the squeezing movement for the heat seal, the film pushing body 20 is first lifted by the up-and-down moving mechanism 24, and the leading edge of the film pushing body 20 is first lifted. Is configured to push up the cylindrical film 1 from below.

따라서, 통형상의 필름(1)은 간헐 반송되고, 필름(1) 내의 피포장물(3)과 피포장물(3)의 중간위치가 상하의 협착체(21,22)간에 위치하는 곳에서 히트시일을 위해 반송 정지하고 나서, 단지 필름 밀어 올림체(20)를 밀어 올리면, 그 선단판 가장자리가 통형상 필름(1)의 히트시일 위치(P)를 항상 확실하게 밀어 올리게 된다.Accordingly, the cylindrical film 1 is intermittently conveyed, and the heat seal is applied where the intermediate position between the packaged object 3 and the packaged object 3 in the film 1 is located between the upper and lower constrictors 21 and 22. If the film pushing up body 20 is only pushed up after conveyance stop, the edge of the front-end | plate plate will always push up the heat-sealing position P of the cylindrical film 1 reliably.

또한, 본 실시예에서는 상기 판 형상의 필름 밀어 올림체(20)의 폭 크기를 통 형상의 필름(1)의 히트시일 위치(P)의 폭크기에 거의 합치할 정도로 설정하고 있고, 또한 필름 밀어 올림체(20)에 의한 필름(1)의 밀어 올림양은 충분히 선단판 가장자리가 필름(1)을 밀어 넣을 수 있도록 설정하고 있다. 그 때문에, 상기 필름 밀어 올림체(20)의 선단판 가장자리는 필름(1)을 아래쪽에서 밀어 넣고, 필름(1)의 하측부분은 히트시일 위치(P)가 솟아오른 가장자리, 즉 통형상의 필름(1)의 폭방향을 따라서 능선이 되도록 산 형상으로 안쪽으로 들어올려지게 된다.In addition, in the present Example, the width | variety size of the said plate-shaped film pushing up body 20 is set so that it may substantially correspond to the width size of the heat-sealing position P of the cylindrical film 1, and also it pushes a film The amount of pushing up of the film 1 by the raising body 20 is set so that the front-end | tip edge can push the film 1 enough. Therefore, the edge of the tip plate of the film pushing-up body 20 pushes the film 1 from the bottom, and the lower part of the film 1 has the edge where the heat seal position P rises, that is, a cylindrical film. It is lifted inward in a mountain shape so as to become a ridge along the width direction of (1).

따라서, 히트시일위치(P)에 설령 피포장물(3)의 부스러기(3A)가 있어도, 상기 밀어 올림 동작에 의해 히트시일위치(P)가 솟아오른 가장자리(능선)가 됨으로써 부스러기(3A)는 나누어져 경사활주 제거된다.Therefore, even if the debris 3A of the packaged object 3 is present at the heat seal position P, the debris 3A is divided by being the edge (ridgeline) where the heat seal position P is raised by the pushing operation. The slope slide is removed.

따라서, 아래쪽 협착체(21)와 위쪽 협착체(22)로 이루어진 종시일장치(6)에 의해 히트시일을 실시하기 전에 미리 상기 필름 밀어 올림체(20)에 의한 밀어 올림 동작을 실시함으로써 시일 불량 원인물(3A)은 히트시일 위치(P)로부터 제거되고 맞물림에 의한 시일 불량을 항상 방지할 수 있게 된다.Therefore, before performing heat sealing with the longitudinal sealing apparatus 6 which consists of the lower constriction body 21 and the upper constriction body 22, the sealing operation | work is performed by performing the pushing up operation by the said film pushing body 20 beforehand. The causative material 3A is removed from the heat seal position P, and it becomes possible to always prevent the sealing defect by the engagement.

또한, 본 실시예에서는 전술한 아래쪽 협착체(21)와 거의 마찬가지로 위쪽 협착체(22)에는 필름(1)의 폭방향을 따르고, 또 필름(1)의 전송방향에 대해 전후방향으로 분단하는 공간부로 이루어진 슬릿부(25)가 설치되고, 이 슬릿부(25)에 의해 상기 위쪽 협착체(21)가 슬릿부를 통하여 2분할로 분단되어 형성되고, 이 분단에 의해 슬릿부(25)를 경계로 하여 그 전후위치에 필름(1)의 폭방향을 따라 2열 히트시일이 실시되도록 구성하고 있다.In the present embodiment, the upper constrictor 22 is spaced along the width direction of the film 1 and divided in the front-rear direction with respect to the transfer direction of the film 1 in almost the same way as the lower constriction 21 described above. The slit part 25 which consists of parts is provided, and the said upper constriction body 21 is divided into 2 parts through the slit part, and it is formed by this slit part 25, and this division makes the slit part 25 boundary. And two rows of heat seals are carried out along the width direction of the film 1 at the front and rear positions thereof.

또한, 상기 슬릿부(25)에 의한 위쪽 협착체(21)의 공간부분에는 상기 2열로 히트시일되는 히트위일 위치(P) 사이를 절단하는 칼날판(7A)을 상하 진퇴 자유롭게 설치하여 절단장치(7)를 구성하고 있다.In addition, in the space portion of the upper constriction body 21 by the slit part 25, a blade plate 7A which cuts between the heat weaving positions P which are heat-sealed in the two rows is installed freely up and down, and the cutting device ( 7)

다음에, 본 실시예의 더욱 구체적인 구성·작동에 대해서 설명한다.Next, a more specific configuration and operation of this embodiment will be described.
