본 발명은 도 2에 도시된 바와 같이 포장기계(100)에 장착되어 전원부로부터 전원이 인가되면 열을 발생시켜 포장지를 열봉합하는 포장기계용 히터의 구조에 관한 것으로써, 도 2 내지 도 6에 도시된 바와 같이, 히터(110)와 히터지지부재(120)와 난연테이프(130) 등을 포함하여 이루어진다.The present invention relates to a structure of a heater for a packaging machine which is mounted on the packaging machine 100 and generates heat when power is applied from the power supply unit as shown in FIG. As shown in the drawing, the heater 110, the heater support member 120, and the flame retardant tape 130 are formed.
본 제1실시예에서 상기 히터(110)는 포장기계(100)의 상부커버(101)에 장착되어있다.In the first embodiment, the heater 110 is mounted on the upper cover 101 of the packaging machine 100.
상기 히터(110)는 도 2 및 도 3에서는 상기 난연테이프(130)에 가려져 도시되지 않았지만, 도 4 및 도 5에 도시된 바와 같이 가열부(111)와 연결부(112)로 이루어진다.Although the heater 110 is not shown as being covered by the flame retardant tape 130 in FIGS. 2 and 3, the heater 110 includes a heating part 111 and a connection part 112 as shown in FIGS. 4 and 5.
상기 가열부(111)는 넓은 면을 갖는 상하면의 폭이 두께보다 큰 형상으로 이루어져 있고, 전원이 인가되면 열을 발생시킨다.The heating part 111 has a shape in which a width of upper and lower surfaces having a wider surface is larger than a thickness and generates heat when power is applied.
상기 가열부(111)는 전원이 인가되면 열을 발생시켜 비닐 재질의 포장지를 식품용기에 중공폐곡선 형상으로 열융착시키는 부분이고, 상기 연결부(112)는 후술하는 바와 같이 상기 가열부(111)를 전원부에 연결하는 부분이다.The heating unit 111 generates heat when power is applied to heat seal the plastic wrapper in a hollow closed curve shape to the food container, and the connection unit 112 is used to heat the heating unit 111 as described below. This part is connected to the power supply.
이러한 상기 가열부(111)는 띠 형상으로 이루어지고, 넓은 면을 갖는 상하면이 두께방향을 중심으로 하여 수평 방향으로 휘어져 중공 폐곡선 형상을 형성한다.The heating part 111 is formed in a band shape, the upper and lower surfaces having a wide surface is bent in a horizontal direction around the thickness direction to form a hollow closed curve shape.
즉, 상기 가열부(111)는 넓은 면을 갖는 상면과 하면이 각각 수평방향으로 동일한 높이를 가지면서 절곡되어 있다.That is, the heating part 111 is bent while the upper and lower surfaces having a wide surface, each having the same height in the horizontal direction.
이때, 상기 가열부(111)는 완전한 중공 폐곡선이 아닌 약간 이격된 형상으로 형성되어 있다고 하더라도, 상기 가열부(111)에서 발생된 복사열 등에 의해 상기 포장지를 식품용기의 테두리에 중공폐곡선 형상으로 열융착시킬 수 있다.At this time, even if the heating part 111 is formed in a slightly spaced shape rather than a complete hollow closed curve, the wrapping paper is heat-sealed in a hollow closed curve shape to the edge of the food container by radiant heat generated from the heating part 111. You can.
따라서, 본 발명에서 히터(110)가 중공폐곡선 형상으로 형성되어 있다는 것은, 완전한 중공폐곡선 뿐만 아니라 약간 이격되어 있지만 포장지를 식품용기의 테두리에 중공폐곡선 형상으로 열융착시키는 구조를 포함하는 의미이다.Therefore, in the present invention, the heater 110 is formed in a hollow closed curve shape, as well as a complete hollow closed curve, but slightly spaced apart, it is meant to include a structure that heat-sealed in a hollow closed curve shape to the edge of the food container.
상기 가열부(111)는 넓은 면을 갖는 상면 또는 하면 중 어느 하나가 외부로 노출되게 장착되어 비닐 재질로 이루어진 포장지 등에 상기 난연테이프(130)를 사이에 두고 접촉함으로써, 상기 전원부로부터 전원이 인가되면 가열되어 상기 포장지를 식품용기 등에 열봉합하게 된다.The heating unit 111 is mounted so that any one of the upper surface or the lower surface having a wide surface is exposed to the outside to contact the wrapping paper made of vinyl material with the flame retardant tape 130 interposed therebetween, so that power is applied from the power supply unit. It is heated to heat seal the wrapping paper or the like.
위와 같은 상기 가열부(111)는 1개 이상의 띠 형상으로 이루어져 도 3 및 도 4에 도시된 바와 같이 끝단을 이루는 일단과 타단이 상호 접하여 중공 폐곡선 형상을 형성하도록 한다.As described above, the heating part 111 is formed of one or more strips so that one end and the other end constituting the end are in contact with each other to form a hollow closed curve shape.
도 3 및 도 4에서는 1개의 상기 가열부(111)를 절곡시켜 중공 폐곡선 형상을 형성하도록 하였지만, 필요에 따라 도 8에 도시된 바와 같이 상기 가열부(111)는 2개 이상인 다수개의 띠 형상으로 분리되어 이루어져 상호 결합됨으로써 중공 폐곡선 형상으로 형성할 수도 있다.In FIG. 3 and FIG. 4, one heating part 111 is bent to form a hollow closed curve shape. However, as shown in FIG. 8, the heating part 111 has a plurality of band shapes of two or more as needed. It may be formed to be separated by mutual coupling to form a hollow closed curve shape.
이때, 도 5에 도시된 바와 같이 상호 접촉하는 상기 가열부(111)의 일단과 타단의 접촉부위에서 상기 포장지에 접하는 면의 높낮이는 동일하여 단차가 없도록 하고, 상호 끊김없이 연결되도록 함이 바람직하다.At this time, as shown in Figure 5, the height of the surface contacting the wrapping paper at the contact portion of the one end and the other end of the heating portion 111 in contact with each other is the same so that there is no step, it is preferable to be connected to each other seamlessly.
그리고, 상기 가열부(111)는 별도의 온도조절장치없이 자체 저항값에 의해 가열되는 재질 예를 들어 저렴한 니크롬선으로 이루어짐이 바람직하다.In addition, the heating unit 111 is preferably made of a material, for example, a cheap nichrome wire that is heated by its own resistance value without a separate temperature control device.
상기 연결부(112)는 상기 가열부(111)를 상기 전원부에 연결하는 역할을 한다.The connection part 112 serves to connect the heating part 111 to the power supply part.
이러한 상기 연결부(112)는 상기 가열부(111)와 같이 저렴한 니크롬선으로 이루어짐이 바람직하고, 상기 가열부(111)와 같이 상하면이 넒은 면을 갖으며 두께가 얇은 띠 형상으로 이루어지도록 한다.The connection portion 112 is preferably made of inexpensive nichrome wire, such as the heating portion 111, and has a thin surface with a thin upper and lower surface, such as the heating portion 111 to have a thin strip shape.
상기 연결부(112)는 상기 가열부(111)의 상부 또는 하부에 배치되어 상기 가열부(111)에 결합된다.The connection part 112 is disposed above or below the heating part 111 and is coupled to the heating part 111.
위와 같은 상기 연결부(112)는, 결합부(113)와 절곡부(114)로 이루어진다.The connection part 112 as described above, the coupling portion 113 and the bent portion (114).
상기 결합부(113)는 상기 접촉부위의 상부 또는 하부에서 상기 가열부(111)의 일단과 타단에 면접촉하면서 결합된다.The coupling part 113 is coupled while being in surface contact with one end and the other end of the heating part 111 in the upper or lower portion of the contact portion.
이때, 상기 결합부(113)는 상기 가열부(111)에 스폿용접 등 다양한 방법을 통해 고정 결합되도록 한다.At this time, the coupling portion 113 is fixed to the heating portion 111 by various methods such as spot welding.
상기 절곡부(114)는 상기 결합부(113)에서 상기 가열부(111)의 반대방향으로 절곡되어 상기 전원부에 연결된다.The bent portion 114 is bent in the opposite direction of the heating portion 111 in the coupling portion 113 is connected to the power supply.
이로 인해, 상기 가열부(111)의 일단과 타단은 상기 결합부(113)에 고정결합되면서 폐곡선 형상으로 상호 접촉되게 된다.As a result, one end and the other end of the heating part 111 are fixedly coupled to the coupling part 113 to be in contact with each other in a closed curve shape.
이러한 상기 연결부(112)는 필요에 따라 상기 가열부(111)의 일단과 타단을 접촉부위가 아닌 다른 부위에서 상기 결합부(113)에 결합될 수도 있다.The connection portion 112 may be coupled to the coupling portion 113 at one end and the other end of the heating portion 111 other than the contact portion as necessary.
위와 같은 상기 연결부(112)는 2개로 이루어져 양전극단자와 음전극단자를 이루도록 한다.The connection part 112 as described above is composed of two to form a positive electrode terminal and a negative electrode terminal.
위 제1실시예와 달리, 도 6에 도시된 바와 같이, 상기 연결부(112)의 일단은 상기 가열부(111)의 일단에서 일체로 연결되어 연장 형성될 수도 있다.Unlike the first embodiment, as shown in FIG. 6, one end of the connection part 112 may be integrally connected and extended from one end of the heating part 111.
즉, 상기 가열부(111)와 연결부(112)가 긴 띠 형상으로 일체로 연결되어 있고, 상기 연결부(112)가 일체로 연결된 상기 가열부(111)의 일단에서 절곡되어 상기 가열부(111)의 상부 또는 하부에 배치되게 할 수도 있다.That is, the heating part 111 and the connection part 112 are integrally connected in a long band shape, and the heating part 111 is bent at one end of the heating part 111 to which the connection part 112 is integrally connected. It may also be arranged above or below.
물론, 도 6에 도시된 바와 같이 상기 가열부(111)와 연결부(112)가 일체로 연결된 경우에도, 상기 가열부(111)는 다수개로 분리되어 상호 결합되어 폐곡선 형상을 형성할 수도 있다.Of course, even when the heating part 111 and the connecting part 112 are integrally connected as shown in FIG. 6, the heating parts 111 may be separated into a plurality of pieces and may be coupled to each other to form a closed curve shape.
그리고, 도 7에 도시된 바와 같이 상기 가열부(111)는 일체로 이루어져 중공 폐곡선 형상을 형성할 수도 있다.As shown in FIG. 7, the heating part 111 may be integrally formed to form a hollow closed curve shape.
이때 상기 가열부(111)는 금속판을 프레스 등을 이용하여 절단하여 제작할 수 있다.In this case, the heating part 111 may be manufactured by cutting a metal plate using a press or the like.
도 7에 도시된 바와 같은 히터(110)의 경우에도 상기 포장지와 접하는 면의 높낮이가 동일하도록 한다.Also in the case of the heater 110 as shown in Figure 7 so that the height of the surface in contact with the wrapping paper is the same.
그리고, 상기 연결부(112)는 상기 가열부(111)와 일체로 형성되어 절곡되도록 한다.In addition, the connection part 112 is integrally formed with the heating part 111 to be bent.
물론, 필요에 따라 상기 연결부(112)를 상기 가열부(111)와 별개로 제작하여 용접 등을 통해 결합시킬 수도 있으나, 바람직하게는 도 7에 도시된 바와 같이 프레스 등을 통해 한번에 상기 가열부(111)와 연결부(112)를 제작한 후 상기 연결부(112)를 절곡시키도록 한다.Of course, if necessary, the connection part 112 may be manufactured separately from the heating part 111 and combined by welding. However, as shown in FIG. After the 111 and the connection part 112 are manufactured, the connection part 112 is bent.
상기 히터지지부재(120)는 일면에 넓은 면을 갖는 상기 가열부(111)의 상면 또는 하면이 외부로 노출되게 결합되는 곳으로써, 난연재질로 이루어진다.The heater support member 120 is a place where the upper surface or the lower surface of the heating unit 111 having a wide surface on one surface is coupled to the outside, made of a flame retardant material.
이때, 상기 연결부(112)는 상기 히터지지부재(120)를 관통하여 상기 전원부에 연결된다.In this case, the connection part 112 is connected to the power supply part through the heater support member 120.
상기 연결부(112)가 도 3 내지 도 6에 도시된 바와 같이 결합부(113)와 절곡부(114)로 이루어진 경우에는 상기 절곡부(114)는 상기 히터지지부재(120)를 관통하여 상기 전원부에 연결된다.3 to 6, when the coupling part 112 is formed of the coupling part 113 and the bent part 114, the bent part 114 penetrates through the heater support member 120 and the power supply part. Is connected to.
그리고, 이때 상기 히터지지부재(120)의 일면에는 상기 결합부(113)가 삽입 배치되는 안착홈(121)이 형성된다.In this case, a seating groove 121 in which the coupling part 113 is inserted is formed on one surface of the heater support member 120.
이와 같이 상기 히터지지부재(120)의 일면에 상기 결합부(113)가 삽입 배치되는 안착홈(121)을 형성함으로써, 상기 연결부(112)가 결합된 부위에서 상기 결합부(113)의 두께에 의해 상기 가열부(111)가 상기 히터지지부재(120)에서 돌출되는 것을 방지할 수 있다.As such, by forming a seating groove 121 in which the coupling part 113 is inserted and disposed on one surface of the heater support member 120, the thickness of the coupling part 113 at a portion where the connection part 112 is coupled. As a result, the heating part 111 may be prevented from protruding from the heater support member 120.
또한, 상기 히터지지부재(120)에는 상기 가열부(111)가 안착되는 배치홈(122)이 형성될 수도 있으며, 이때 상기 안착홈(121)은 상기 배치홈(122)보다 더 깊게 형성된다.In addition, the heater support member 120 may be formed with a placement groove 122 in which the heating part 111 is seated, wherein the seating groove 121 is formed deeper than the placement groove 122.
한편, 상기 연결부(112)가 도 7에 도시된 바와 같이 상기 가열부(111)에 일체로 연결된 경우에는 상기 연결부(112)에 의해 히터(110)의 두께가 두꺼워지는 것이 아닌바 상기 안착홈(121)과 같은 구성이 불필요하게 된다.On the other hand, when the connection part 112 is integrally connected to the heating part 111 as shown in FIG. 7, the thickness of the heater 110 is not increased by the connection part 112. 121, such a configuration is unnecessary.
그리고, 상기 연결부(112)가 상기 가열부(111)와 동일한 재질로 이루어져 전원이 인가되면 외부로 열을 발생시키는 경우에, 본 발명은 상기 히티지지부재(120)의 타면에 결합되어 상기 히터지지부재(120)를 상부커버(101) 등을 포함하는 포장기계에 연결하여 고정결합시키는 고정지지부재(102)를 더 포함하여 이루어질 수도 있다.In addition, when the connection part 112 is made of the same material as the heating part 111 and generates heat to the outside when power is applied, the present invention is coupled to the other surface of the hit support member 120 to support the heater. It may further comprise a fixed support member 102 for fixing and coupling the member 120 to the packaging machine including the upper cover 101 and the like.
상기 고정지지부재(102)는 ABS 등과 같은 플라스틱 재질로 이루어지고, 상기 히터지지부재(120)를 상기 상부커버(101) 등에 결합시키는 역할을 한다.The fixed support member 102 is made of a plastic material such as ABS, and serves to couple the heater support member 120 to the upper cover 101 or the like.
이때, 상기 히터지지부재(120)의 타면에는 상기 가열부(111)가 배치된 방향의 반대방향인 상기 고정지지부재(102) 방향으로 가열방지돌기(125)가 돌출 형성되어 있다.At this time, the other surface of the heater support member 120 is formed with a heating preventing projection 125 protruding in the direction of the fixed support member 102 in the opposite direction to the direction in which the heating portion 111 is disposed.
상기 가열방지돌기(125)는 상기 고정지지부재(102)를 관통하도록 되어 있고, 상기 연결부(112)는 상기 가열방지돌기(125)를 관통한다.The heat preventing protrusion 125 penetrates the fixed support member 102, and the connection part 112 penetrates the heat preventing protrusion 125.
즉, 열을 발생시키는 상기 연결부(112)는 상기 가열방지돌기(125)에 의해 상기 고정지지부재(102)에 직접적으로 접하지 못하게 된다.That is, the connection part 112 that generates heat is not directly in contact with the fixed support member 102 by the heating preventing protrusion 125.
이로 인해, 상기 연결부(112)에서 발생된 열이 난연재질로 이루어진 상기 가열방지돌기(125)에 의해 차단되어, 상기 고정지지부재(102)를 플라스틱으로 제작할 경우에도 상기 고정지지부재(102) 등이 상기 연결부(112)에서 발생된 열에 의해 변형되는 것을 방지할 수 있다.Thus, the heat generated from the connection portion 112 is blocked by the heating preventing protrusion 125 made of a flame retardant material, even when the fixed support member 102 is made of plastic, the fixed support member 102, etc. It can be prevented from being deformed by the heat generated in the connecting portion 112.
상기 난연테이프(130)는 외부로 노출된 상기 가열부(111)를 덮으면서 상기 히터지지부재(120)에 접착된다.The flame retardant tape 130 is bonded to the heater support member 120 while covering the heating part 111 exposed to the outside.
이때, 상기 난연테이프(130)는 끊김없이 상기 가열부(111)를 덮으면서 상기 히터지지부재(120)에 접착되도록 함이 바람직하다.At this time, the flame retardant tape 130 is preferably bonded to the heater support member 120 while covering the heating portion 111 without interruption.
한편, 상기 가열부(111)는 도 8에 도시된 바와 같이 제1가열부(111a)로 제2가열부(111b)로 이루어지고, 상기 연결부(112)는 제1연결부(112a)와 제2연결부(112b)로 이루어질 수도 있다.Meanwhile, as shown in FIG. 8, the heating part 111 includes the first heating part 111a and the second heating part 111b, and the connection part 112 includes the first connection part 112a and the second connection part. It may be made of a connecting portion (112b).
상기 제1가열부(111a)는 포장지(160)의 일부를 식품용기(165)에 열융착시킨다.The first heating part 111a heat seals a part of the wrapping paper 160 to the food container 165.
상기 제2가열부(111b)는 상기 제1가열부(111a)와 동일한 수평면상에 배치되어, 상기 포장지(160)의 나머지를 식품용기(165)에 열융착시킨다.The second heating part 111b is disposed on the same horizontal plane as the first heating part 111a, and thermally seals the rest of the wrapping paper 160 to the food container 165.
상기 제1연결부(112a)는 상기 제1가열부(111a)에 일체로 연결되고, 상기 제2연결부(112b)는 상기 제2가열부(111b)에 일체로 연결된다.The first connector 112a is integrally connected to the first heating unit 111a, and the second connector 112b is integrally connected to the second heating unit 111b.
이때, 상기 제1가열부(111a)와 제2가열부(111a)는 각각 일체로 연결된 상기 제1연결부(112a) 및 제2연결부(112b)가 절곡되면서 라운드진 절곡부위에 의해 상호 미세하게 이격되게 된다.At this time, the first heating portion 111a and the second heating portion 111a are finely spaced apart from each other by rounded bending portions while the first connecting portion 112a and the second connecting portion 112b are integrally connected to each other. Will be.
따라서, 상기 제1가열부(111a)와 제2가열부(111b)는 라운드진 부분 즉 상기 가열부(111)와 연결부(112)의 절곡부분에서 약간 상호 이격되어, 동일평면상에서 상기 제1가열부(111a) 및 제2가열부(111b) 자체만으로는 중공폐곡선형상을 이루지 못하게 된다.Therefore, the first heating part 111a and the second heating part 111b are slightly spaced apart from each other in a rounded part, that is, the bent part of the heating part 111 and the connection part 112, and the first heating part is on the same plane. Only the portion 111a and the second heating portion 111b itself do not form a hollow closed curve shape.
이러한 구조에서는, 상기 제1가열부(111a)와 제2가열부(111b)가 이격된 위치의 하부에 위치하는 상기 포장지(160)는, 상기 제1가열부(111a)와 제2가열부(111b)의 라운드진 절곡부분 즉 상기 가열부(111)와 연결부(112)의 절곡부위에서 발생된 복사열에 의해 가열되어 상기 식품용기(165)에 열융착되게 된다.In this structure, the wrapping paper 160 positioned below the first heating portion 111a and the second heating portion 111b is separated from the first heating portion 111a and the second heating portion ( The rounded bent portion of 111b, that is, the heat is radiated by the radiant heat generated at the bent portion of the heating portion 111 and the connection portion 112 is heat-sealed to the food container 165.
따라서, 상기 제1가열부(111a)와 제2가열부(111b)가 약간 상호 이격되어 있어도, 상기 히터에 의해 상기 포장지(160)는 식품용기(165)에 중공폐곡선 형상으로 열융착되게 된다.Therefore, even if the first heating portion 111a and the second heating portion 111b are slightly spaced apart from each other, the wrapping paper 160 is thermally fused to the food container 165 in a hollow closed curve shape by the heater.
이하, 상술한 구성으로 이루어진 본 발명의 조립과정에 대하여 살펴본다.Hereinafter, a look at the assembly process of the present invention made of the above-described configuration.
먼저, 띠 형상으로 이루어진 상기 가열부(111)를 절곡기계 등을 이용하여 두께방향을 중심으로 하여 수평방향으로 절곡시킨다.First, the heating part 111 having a strip shape is bent in the horizontal direction by using a bending machine or the like about the thickness direction.
이때, 상기 가열부(111)의 끝단을 이루는 일단과 타단이 상호 접할 수 있게 절곡한다.At this time, one end and the other end forming the end of the heating unit 111 is bent to be in contact with each other.
상기 가열부(111)가 다수개의 띠 형태로 이루어진 경우에는 각각의 가열부(111)가 연결되어 폐곡선 형상으로 이루어지도록 한다.When the heating unit 111 is formed of a plurality of strips, each heating unit 111 is connected to form a closed curve.
그리고, 띠 형상을 이루는 2개의 상기 연결부(112)를 절곡시켜 결합부(113)와 절곡부(114)를 형성한다.Then, the two connecting portions 112 having a band shape are bent to form a coupling portion 113 and a bent portion 114.
그 후 상기 결합부(113)를 상기 가열부(111)의 상면 또는 하면에 스폿용접 등을 통해 결합시킨다.Thereafter, the coupling part 113 is coupled to the upper or lower surface of the heating part 111 by spot welding or the like.
이때, 1개의 상기 연결부(112)는 상기 가열부(111)의 일단과 타단이 상호 접하도록 한 상태에서 상기 결합부(113)를 상기 가열부(111)의 일단과 타단에 모두 결합하여, 상기 가열부(111)의 일단과 타단이 연결된 중공 폐곡선 형상을 이루도록 한다.In this case, one connection portion 112 is coupled to both the one end and the other end of the heating portion 111 in the state in which one end and the other end of the heating portion 111 in contact with each other, One end and the other end of the heating unit 111 to form a hollow closed curve shape.
그리고, 나머지 1개의 상기 연결부(112)는 반대편에서 상기 가열부(111)에 결합되도록 한다.And, the other one connecting portion 112 is coupled to the heating portion 111 on the opposite side.
이로 인해 2개의 상기 연결부(112)는 상기 전원부에 연결되는 양전극단자와 음전극단자를 이루게 된다.As a result, the two connecting portions 112 form a positive electrode terminal and a negative electrode terminal connected to the power supply unit.
위와 같이 상기 히터(110)의 제작이 완성되면, 상기 히터(110)를 상기 히터지지부재(120)에 장착한다.When the production of the heater 110 is completed as described above, the heater 110 is mounted on the heater support member 120.
이때, 상기 연결부(112)는 상기 히터지지부재(120)를 관통하여 장착되고, 상기 결합부(113)는 상기 히터지지부재(120)의 일면에 형성된 안착홈(121)에 삽입 배치된다.In this case, the connection part 112 is mounted through the heater support member 120, and the coupling part 113 is inserted into the seating groove 121 formed on one surface of the heater support member 120.
이로 인해, 상기 가열부(111)와 상기 히터지지부재(120) 사이에 상기 결합부(113)가 배치되어 있어도, 상기 결합부(113)가 상기 안착홈(121)에 삽입 배치되어 있는바, 상기 가열부(111)가 상기 결합부(113)의 두께만큼 돌출되는 것을 방지할 수 있다.Therefore, even when the coupling part 113 is disposed between the heating part 111 and the heater support member 120, the coupling part 113 is inserted into the seating groove 121. It is possible to prevent the heating part 111 from protruding by the thickness of the coupling part 113.
따라서, 상기 가열부(111)는 전체적으로 그 높낮이가 동일하게 되어 포장지의 둘레를 따라 빈틈없이 전체적으로 열봉합할 수 있다.Therefore, the height of the heating part 111 is the same as the whole can be heat-sealed as a whole along the circumference of the wrapping.
상기 히터(110)를 상기 히터지지부재(120)에 장착한 후에는 상기 난연테이프(130)를 통해 상기 히터(110)를 덮도록 한다.After the heater 110 is mounted on the heater support member 120, the heater 110 is covered by the flame retardant tape 130.
한편, 도 7에 도시된 바와 같이 프레스 등을 이용하여 자체 저항값을 갖는 금속판을 절단함으로써 상기 가열부(111) 및 연결부(112)가 끊김없이 일체로 제작할 경우에는 프레스공정을 통해 폐곡선 형상의 상기 가열부(111)와 연결부(112)를 일체로 절단하여 상기 히터(110)를 제작되도록 한다.On the other hand, by cutting the metal plate having its own resistance value using a press or the like as shown in Figure 7, when the heating portion 111 and the connecting portion 112 is produced integrally without interruption of the closed curve shape through the pressing process The heater 110 is manufactured by integrally cutting the heating part 111 and the connection part 112.
본 발명의 상기 히터(110)는 포장기계의 상부커버(101) 전체면에 장착된 것이 아니라 열봉합하고자 하는 둘레 부위에만 장착되어 있는바, 열의 발생량이 적어 히터(110)가 장착되는 상기 상부커버(101)를 합성수지재로도 제작할 수도 있다.The heater 110 of the present invention is not mounted on the entire surface of the upper cover 101 of the packaging machine, but is mounted only on the circumferential portion to be heat-sealed, and the upper cover is mounted on the heater 110 because the amount of heat generated is small. It is also possible to produce 101 as a synthetic resin material.
또한, 위에서는 상기 히터(110)가 두께가 얇은 띠 형상으로 형성된 것을 설명하였지만, 상기 히터는 단면이 원형 또는 다각형으로 이루어져 위와 같은 구조로 장착될 수도 있다.In addition, although the heater 110 has been described as being formed in a thin strip shape, the heater may be mounted in the same structure as the cross section is made of a circular or polygonal.

도 9는 본 발명의 제2실시예에 따른 포장기계용 히터의 사시도이고, 도 10은 본 발명의 제2실시예에 따른 포장기계용 히터의 분해사시도이며, 도 11은 도 9의 B-B'선을 취하여 본 단면도이다.9 is a perspective view of a heater for a packaging machine according to a second embodiment of the present invention, Figure 10 is an exploded perspective view of a heater for a packaging machine according to a second embodiment of the present invention, Figure 11 is B-B of Figure 9 'This is a cross-sectional view taken on line.
도 9 내지 도 11에 도시된 바와 같이 본 발명의 히터(150)는 제1히터부(150a)와 제2히터부(150b)로 분할되어 이루어진다.As shown in FIGS. 9 to 11, the heater 150 of the present invention is divided into a first heater part 150a and a second heater part 150b.
상기 제1히터부(150a)는 제1가열부(151a)와 제1연결부(152a)로 이루어지고, 상기 제2히터부(150b)는 제2가열부(151b)와 제2연결부(152b)로 이루어진다.The first heater unit 150a includes a first heating unit 151a and a first connection unit 152a, and the second heater unit 150b includes a second heating unit 151b and a second connection unit 152b. Is made of.
상기 제1가열부(151a)와 제2가열부(151b)는 상기 가열부가 분할되어 이루어진 것으로써 띠 형상으로 이루어져 있고, 상기 제1연결부(152a) 및 제2연결부(152b)는 상기 연결부가 분할되어 이루어진 것이다.The first heating part 151a and the second heating part 151b are formed by splitting the heating part and have a band shape, and the first connecting part 152a and the second connecting part 152b are divided by the connecting part. It is done.
띠 형상의 상기 제1가열부(151a)와 제2가열부(151b)는 결합되어 중공폐곡선 형상을 이루어진다.The band-shaped first heating part 151a and the second heating part 151b are combined to form a hollow closed curve shape.
상기 제1연결부(152a)는 상기 제1가열부(151a)에 일체로 연결되고, 상기 제2연결부(152b)는 상기 제2가열부(151b)에 일체로 연결되어 있다.The first connector 152a is integrally connected to the first heating unit 151a, and the second connector 152b is integrally connected to the second heating unit 151b.
본 실시예에서 상기 제1가열부(151a)와 제2가열부(151b)는 각각 '⊂','⊃'형상으로 최대한 공간없이 붙어 형성되고, 상기 제1연결부(152a)와 제2연결부(152b)는 각각 2개로 이루어져, 상기 제1가열부(151a) 및 제2가열부(151b)의 일단 및 타단에 각각 연결되어 있다.In the present embodiment, the first heating part 151a and the second heating part 151b are formed to be spaced apart as much as possible in a '⊂' and '⊃' shape, respectively, and the first connection part 152a and the second connection part ( Two pieces 152b are connected to one end and the other end of the first heating part 151a and the second heating part 151b, respectively.
이러한 상기 제1히터부(150a)와 제2히터부(150b)는 그 길이 및 형상이 동일하여, 상기 제1연결부(152a) 및 제2연결부(152b)를 통해 전원이 인가되었을 때, 상기 제1히터부(150a)와 제2히터부(150b)에서 발생되는 발열량이 동일하도록 하여 포장기가 식품용기에 균일하게 열융착되도록 할 수 있다.The first heater part 150a and the second heater part 150b have the same length and shape, and when the power is applied through the first connection part 152a and the second connection part 152b, The amount of heat generated by the first heater unit 150a and the second heater unit 150b may be the same so that the packaging machine may be uniformly heat-sealed in the food container.
만일, 상기 제1히터부(150a)와 제2히터부(150b)의 길이 또는 형상이 다르게 되면, 상기 제1히터부(150a)와 제2히터부(150b)에서 발생되는 발열량에 차이가 발생하게 되고, 이로 인해 포장지를 전체적으로 균일하게 열융착할 수 없게 되는 문제가 발생할 수 있다.If the lengths or shapes of the first heater part 150a and the second heater part 150b are different from each other, a difference occurs in the amount of heat generated by the first heater part 150a and the second heater part 150b. And, this may cause a problem that can not be heat-sealed uniformly as a whole wrapper.
이는 상기 히터(150)가 자체 저항값에 의해 가열되는 재질로 이루어져 있기 때문에, 그 길이 및 형상에 따라 발열량에 차이가 발생할 수 있기 때문이다.This is because the heater 150 is made of a material that is heated by its own resistance value, it is because there may be a difference in the amount of heat generated according to the length and shape.
그리고, 본 발명의 히터(150)는, 상기 제1연결부(152a)와 제2연결부(152b) 사이에 배치되는 절연부재(155)를 더 포함하여 이루어질 수도 있다.In addition, the heater 150 of the present invention may further include an insulating member 155 disposed between the first connecting portion 152a and the second connecting portion 152b.
상기 절연부재(155)는 상기 제1연결부(152a)와 제2연결부(152b) 사이에 배치되어 상기 제1연결부(152a)와 제2연결부(152b)가 상호 접하는 곳이 다른 곳보다 과열되는 것을 방지한다.The insulating member 155 is disposed between the first connecting portion 152a and the second connecting portion 152b so that the place where the first connecting portion 152a and the second connecting portion 152b contact each other is overheated. prevent.
보다 자세하게 설명하면, 상기 제1연결부(152a)와 제2연결부(152b)는 각각 자체 저항값에 의해 가열되는 재질로 이루어져 있는바, 상기 제1연결부(152a)와 제2연결부(152b)가 상호 접하는 곳에서는 서로 합쳐져 다른 곳보다 더 높은 발열량이 발생하게 된다.In more detail, the first connecting portion 152a and the second connecting portion 152b are each made of a material heated by its own resistance value, and the first connecting portion 152a and the second connecting portion 152b mutually Where they come into contact, they merge with each other, resulting in higher calorific values than other places.
이를 그대로 사용하게 되면, 상기 제1연결부(152a)와 제2연결부(152b)가 상호 접하는 부위는 온도가 높아 포장지를 식품용기에 균일한 온도로 열융착시킬 수 없게 된다.If it is used as it is, the portion where the first connection portion 152a and the second connection portion 152b are in contact with each other is not high temperature can not be heat-sealed wrapping paper at a uniform temperature in the food container.
그러나, 본 발명과 같이 상기 제1연결부(152a)와 제2연결부(152b) 사이에 상기 절연부재(155)를 배치함으로써, 상기 제1연결부(152a)와 제2연결부(152b)가 상호 접하여 발열량이 증가되는 것을 방지할 수 있다.However, by disposing the insulating member 155 between the first connector 152a and the second connector 152b as in the present invention, the first connector 152a and the second connector 152b are in contact with each other to generate heat. This can be prevented from increasing.
이때, 상기 절연부재(155)가 배치된 부위의 하부에서는 상기 제1가열부(151a)와 제2가열부(151b)가 상기 포장지에 직접적으로 접촉되어 가열하지 않지만, 상기 절연부재(155)가 얇고 상기 제1가열부(151a)와 제1연결부(152a)의 절곡부위와 상기 제2가열부(152b) 및 제2연결부(152b)의 열이 전달됨으로써, 상기 포장지가 가열되어 식품용기의 테두리에 중공폐곡선 형상으로 열융착되게 된다.At this time, the first heating part 151a and the second heating part 151b are not directly heated in contact with the wrapping paper at the lower portion of the portion where the insulating member 155 is disposed, but the insulating member 155 is A thin, bent portion of the first heating unit 151a and the first connection unit 152a and the heat of the second heating unit 152b and the second connection unit 152b are transferred, thereby heating the wrapping paper to the edge of the food container. Heat-sealed in the shape of a hollow closed curve.
즉, 상기 제1가열부(151a)와 제2가열부(151b)가 완전한 중공폐곡선을 이루지 않더라도, 복사열 등에 의해 상기 본 발명의 히터(150)는 포장지를 식품용기의 테두리에 중공폐곡선 형상으로 열융착시킬 수 있게 된다.That is, even if the first heating unit 151a and the second heating unit 151b do not form a complete hollow closed curve, the heater 150 of the present invention heats the wrapping paper in a hollow closed curve shape at the edge of the food container by radiant heat or the like. It can be fused.
물론, 상기 제1연결부(152a)와 제2연결부(152b)는 상기 제1가열부(151a) 및 제2가열부(151b)로부터 멀리 떨어진 곳에서는 상호 접하여 있을 수도 있다.Of course, the first connecting portion 152a and the second connecting portion 152b may be in contact with each other at a distance away from the first heating portion 151a and the second heating portion 151b.
또한, 본 실시예에서도 상기 히터(150)는 띠 형상 즉 단면이 직사각형으로 이루어질 수도 있고, 원형 또는 다각형상으로 이루어질 수도 있다.In addition, in the present embodiment, the heater 150 may be formed in a strip shape, that is, a rectangular cross section, or may be formed in a circular or polygonal shape.
위와 같이 상기 히터(150)가 상기 절연부재(155)를 포함하여 이루어진 경우에는, 상기 제1가열부(151a), 절연부재(155) 및 제2가열부(151b)가 결합되어 중공폐곡선 형상을 이루게 된다.When the heater 150 includes the insulating member 155 as described above, the first heating part 151a, the insulating member 155, and the second heating part 151b are combined to form a hollow closed curve shape. Is achieved.
