본 발명은 직접 가열수단을 갖는 코팅장치용 히팅롤러 장치에 관한 것이다.The present invention relates to a heating roller apparatus for a coating apparatus having a direct heating means.

상세하게 본 발명은, 외부의 전기 전원에 의해 발열된 히터가 롤러를 직접가열할 수 있도록 하여 롤러를 가열시키기 위한 열 전달효율을 최대화하고, 히터의 코일 배치를 개량하여 원지와 접촉되는 작업구간은 균일한 발열량을 얻을 수 있도록 함과 동시에 원지가 접촉되지 않은 구간은 발열량이 없거나 낮도록 하여 우수한 작업결과 및 이송롤러의 파손을 해소할 수 있도록 하며, 작업물의 진행에 의해 롤러의 유동이 발생되어도 전기 전원의 공급이 안정적으로 수행될 수 있도록 하여 장치의 신뢰성을 확보할 수 있도록 한 직접 가열수단을 갖는 코팅장치용 히팅롤러 장치에 관한 것이다.In detail, the present invention maximizes the heat transfer efficiency for heating the rollers by allowing the heaters generated by the external electric power to directly heat the rollers, and improves the coil arrangement of the heaters so that the working section is in contact with the original paper. In order to obtain a uniform heating value and at the same time the section where the paper is not in contact with the paper, the heating value is low or low so that excellent work results and breakage of the transfer roller can be eliminated. The present invention relates to a heating roller device for a coating apparatus having a direct heating means to ensure the supply of power to ensure a stable device.

음식료품이나 공산물 포장지 또는 각종 판플렛, 광고 전단지 등(이하, 원지)에는 대부분 특정의 모양이 인쇄되고, 이와 같은 인쇄상태를 장기간 유지하며 고급 스러운 미감을 제공하기 위해 인쇄면에는 코팅이 수행된다.Most foods or industrial products or various leaflets, advertising leaflets, etc. (hereinafter, original paper) are mostly printed on a specific shape, and the printing is coated on the printed surface to maintain such a printing state for a long time and provide a luxurious aesthetic.

이와 같은 코팅은 원지를 공급하여 코팅하고, 코팅과정이 수행된 면을 건조한 후 완성된 제품의 형태로 배출시키기 위한 전용의 코팅장치에 의해 수행됨은 전술한 것과 같다.Such coating is carried out by a coating apparatus for supplying a base paper and coating the surface, and drying the surface on which the coating process is performed, and then discharging it in the form of a finished product.

이러한 코팅장치의 구성에서 코팅이 수행되는 원지는 히팅롤러에 의해 가열 압착되어 작업이 수행된다. 도 2는 상기 종래의 히팅롤러 구성을 나타낸 단면도이다.In the construction of such a coating apparatus, the base on which the coating is performed is heat-compressed by a heating roller to perform an operation. 2 is a cross-sectional view showing a conventional heating roller configuration.

도면을 참조하면, 종래의 히팅롤러는 금속재의 원통으로 형성된 롤러(1)의 내부에 다수의 히터(2)가 일체화된 발열체(3)가 배치되어 구성된다. 이 때, 상기 히터(2)는 외부의 전기 전원을 입력받아 발열되기 위해 롤러(1)가 회전되어도 회전되지 않으며, 이를 위해 상기 발열체(3)는 롤러(1)의 내주면과 적당한 간격을 유지하며 배치된다.Referring to the drawings, the conventional heating roller is configured by arranging a heating element 3 in which a plurality of heaters 2 are integrated in a roller 1 formed of a metal cylinder. At this time, the heater 2 is not rotated even if the roller 1 is rotated to generate heat by receiving external electrical power, for this purpose, the heating element 3 maintains a proper distance from the inner peripheral surface of the roller (1) Is placed.

이러한 구성에서 상기 발열체(3)의 히터(2)는 전기 전원에 의해 발열되기 위한 코일히터 외에도, 흡사 보일러 시스템과 같이 발열체(3)를 일정온도 이상의 고온증기가 순환되는 순환파이프 등으로 구성하여 롤러(1)를 가열하는 구성도 사용되지만, 고온증기를 생성하고 순환시키는 시스템의 특징상 과도한 기름의 사용에 따른 경제적 손실에 기인하여 사용이 자제되고 있는 실정이다.In this configuration, the heater 2 of the heating element 3 is configured by a circulating pipe through which the high temperature steam of a predetermined temperature or more is circulated, in addition to the coil heater for generating heat by the electric power, similar to a boiler system. The configuration of heating (1) is also used. However, due to the characteristics of the system for generating and circulating high temperature steam, the use is restricted due to the economic loss caused by the use of excessive oil.

또한, 참고적으로 상기 히팅롤러에서 발생되어야 하는 열은 대략 110℃ ~ 120℃ 정도이며, 도면 중 히팅롤러와 인접한 롤러는 외면이 고무 등의 마찰부재로 제작되어 원지(P)의 이송을 수행하는 이송롤러(F)이다.In addition, the heat that should be generated in the heating roller for reference is about 110 ℃ ~ 120 ℃ degree in the drawing, the roller adjacent to the heating roller in the drawing is made of a friction member such as rubber to carry out the transfer of the paper (P) Feed roller (F).

상기와 같은 종래의 히팅롤러는 고정된 발열체의 외부에서 롤러가 회전됨으로 인해 발열체와 롤러는 접촉이 불가능하기 때문에 발열체에서 발생된 열이 발열체와 롤러 사이의 공간을 대류시킨 후 롤러를 가열하게 된다. 이에 따라 상기 발열체에서 발생된 열의 전달효율은 지극히 낮아지게 된다. 특히, 상기 낮은 열 전달효율에 의해 롤러를 목적하는 온도로 가열시키기 위해서는 히터의 개수를 증설해야 함은 필수적인 것으로 히터의 증설에 따른 제작비용의 상승에 따라 경제적인 불이익이 발생된다.In the conventional heating roller as described above, since the heating element and the roller cannot be contacted because the roller is rotated outside the fixed heating element, heat generated in the heating element convections the space between the heating element and the roller to heat the roller. Accordingly, the heat transfer efficiency generated from the heating element is extremely low. In particular, it is essential to increase the number of heaters in order to heat the rollers to the desired temperature by the low heat transfer efficiency, and economic disadvantages arise as the manufacturing cost increases due to the expansion of the heaters.

또한, 상기 히팅롤러는 히터의 전원이 입력되는 측단부가 상당히 높은 온도의 열을 발생시키는 반면, 히터의 길이에 의해 그 반대측단부는 상당히 낮은 온도의 열을 발생시키기 때문에 롤러가 원지와 접촉되는 작업구간은 길이방향에 걸쳐 불균일한 발열량을 갖게 된다. 특히, 상기 롤러의 온도가 낮은 지점을 작업이 가능한 온도로 설정하게 되면 그 타측(전원의 입력측)의 온도는 작업온도를 초과하는 발열량(대략 200℃)을 갖기 때문에 히팅롤러와 인접한 이송롤러의 외면이 초과되는 열에 의해 파손(대체로 열에 의한 균열이 발생)되어 이송롤러를 자주 교체해야 하는 문제점이 노출된다.In addition, in the heating roller, the side end portion to which the heater's power is input generates heat at a considerably high temperature, while the opposite end portion generates heat at a relatively low temperature due to the length of the heater, so that the roller is in contact with the base paper. The section has a nonuniform amount of heat generation in the longitudinal direction. In particular, when the temperature of the roller is set to a temperature at which the work is possible, the temperature of the other side (the input side of the power supply) has a calorific value (approximately 200 ° C.) exceeding the working temperature, so that the outer surface of the transfer roller adjacent to the heating roller is This excess heat breaks (generally causing cracks due to heat) and exposes the problem of frequently replacing the feed roller.

본 발명은 상기 문제점을 해결하기 위해 발명한 것이다.The present invention has been invented to solve the above problems.

이에 본 발명은, 롤러의 내측에서 히터가 롤러와 접촉한 상태로 발열되어 히 터에서 롤러로 전달되는 열 효율을 최대화하며, 롤러의 작업구간에 대해 길이방향에 걸쳐 균일한 열을 발생시킬수 있도록 함과 동시에 작업되지 않는 구간에서는 발열량이 없거나 낮도록 하며, 작업물의 진행에 의해 롤러의 유동이 발생되어도 전기 전원이 안정적으로 히터에 인가될 수 있도록 한 히팅롤러 장치를 제공함에 그 목적이 있다.Accordingly, the present invention, the heater is heated in the state in contact with the roller in the interior of the roller to maximize the thermal efficiency transferred from the heater to the roller, it is possible to generate a uniform heat in the longitudinal direction for the working period of the roller In the non-working section at the same time, the heat generation is low or low, and the object of the present invention is to provide a heating roller apparatus that can be applied to the heater stably even if the flow of the roller generated by the progress of the workpiece.

상기 목적을 달성하기 위해 본 발명은 아래의 구성을 갖는다.In order to achieve the above object, the present invention has the following configuration.

본 발명은, 원지의 코팅면을 가열하며 가압하기 위해 원지의 이송구간에서 회전가능하게 설치된 롤러와; 상기 롤러의 회전축을 중심으로 방사상 다수개가 롤러의 길이방향에 따라 삽입되어 설치되므로써, 롤러에 끼워져 접촉된 상태에서 롤러를 직접 가열하는 히터;를 포함하여 구성된다.The present invention includes a roller rotatably installed in the transfer section of the paper for heating and pressing the coating surface of the paper; The radial plurality of radially around the rotation axis of the roller is inserted and installed along the length direction of the roller, so that the heater to directly heat the roller in the contact state is fitted to the roller; is configured to include.

이 때, 상기 히터는 외부의 전기 전원을 공급받아 코일이 발열되는 전기히터이며, 상기 코일은 이송되는 원지와 접촉되는 롤러의 작업구간과 대응하는 길이방향의 구간이 높은 조밀도로 권선되고, 원지와 접촉되지 않는 롤러의 작업구간과 대응하는 코일의 전원 입력측부는 낮은 조밀도로 권선되어 구성된다.At this time, the heater is an electric heater in which the coil is heated by receiving external electric power, and the coil is wound at a high density in a longitudinal section corresponding to the working section of the roller in contact with the conveyed paper. The power input side of the coil corresponding to the working section of the roller that is not in contact is wound with low density.

특히, 상기 히터는 롤러의 작업구간과 대응하는 코일의 길이방향 구간이 전원의 입력측부에서 그 타측으로 점차 높은 조밀도를 갖도록 권선되어 롤러의 작업구간 길이방향에 걸쳐 균일한 발열량을 갖도록 구성된다.In particular, the heater is configured such that the longitudinal section of the coil corresponding to the working section of the roller is wound so as to have a higher density gradually from the input side of the power source to the other side thereof to have a uniform amount of heat generated over the length of the working section of the roller.

또한, 상기 히터는 외부의 전기 전원을 공급하는 파워서플라이와 전기적으로 연결되며, 롤러의 회전 및 유동에 의해 전원의 공급이 가능하도록 하기 위해 슬립링이 개재되어 구성된다.In addition, the heater is electrically connected to a power supply for supplying external electric power, and the slip ring is interposed to enable the supply of power by the rotation and flow of the roller.

이상에서와 같이 본 발명은, 롤러가 히터에 의해 직접 가열되어 히터에서 롤러로 전달되는 열 효율이 최대화되므로써 보다 적은 개수의 히터로도 발열체를 구성함에 따라 제작비용의 절감 및 에너지 절감의 효과를 얻게 된다.As described above, according to the present invention, the roller is directly heated by the heater to maximize the thermal efficiency transferred from the heater to the roller, thereby constituting the heating element with a smaller number of heaters, thereby reducing the manufacturing cost and saving energy. do.

또한, 본 발명은 히터의 길이방향에 따라 코일의 조밀도를 다르게 설정하여 배치하므로써 롤러가 작업구간의 길이방향에 걸쳐 균일한 발열량을 갖도록 함과 동시에 작업구간 이외의 구간은 발열량이 없거나 현저하게 낮도록 하여 보다 우수한 작업결과를 얻을 수 있게 되며, 작업온도보다 초과되는 열에 의해 이송롤러가 파손되는 우려를 해소할 수 있는 효과가 있다.In addition, according to the present invention, by setting the density of the coil differently according to the length direction of the heater, the rollers have a uniform heat generation amount in the length direction of the work section and at the same time, the sections other than the work section have no or low heat generation. It is possible to obtain a better working result, there is an effect that can eliminate the fear that the transfer roller is damaged by the heat exceeding the working temperature.

동시에 본 발명은, 이송되는 원지에 의해 롤러의 유동이 발생되어도 전기 전원이 슬립링에 의해 안정적으로 공급되므로써 장치와 작업의 신뢰도를 향상시킬 수 있도록 한 효과가 있다.At the same time, the present invention has the effect of improving the reliability of the apparatus and the work by supplying the electric power stably by the slip ring even if the roller is generated by the conveyed paper.

상기와 같은 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 의한 히팅롤러 장치의 사시도, 도 3은 본 발명에 의한 히팅롤러 장치의 단면도, 도 4는 본 발명에 의한 히팅롤러 장치 중 히터의 코일 배치 도, 도 5는 본 발명에 의한 히팅롤러 장치에 전기전원이 공급되는 개략도이다.Figure 2 is a perspective view of the heating roller device according to the present invention, Figure 3 is a cross-sectional view of the heating roller device according to the present invention, Figure 4 is a coil arrangement of the heater of the heating roller device according to the present invention, Figure 5 is according to the present invention It is a schematic diagram in which electric power is supplied to a heating roller apparatus.

도면을 참조하면, 본 발명에 의한 히팅롤러 장치는 롤러(10)와, 히터(20)로 구성된다. 이와 같은 히팅롤러 장치는 도면에서와 같이 롤러(10) 인근에 이송롤러(F)가 배치된다. 이 때, 상기 이송롤러(F)는 외면이 고무 등의 마찰부재로 피복되어 원지(P)의 이송을 원활하게 수행하도록 구성됨은 주지된 것과 같다.Referring to the drawings, the heating roller device according to the present invention is composed of a roller 10, the heater 20. In this heating roller device, a feed roller F is disposed near the roller 10 as shown in the drawing. At this time, the feed roller (F) is the outer surface is coated with a friction member such as rubber is configured to smoothly carry out the transfer of the paper (P) as is known.

상기 롤러(10)는 코팅을 수행하기 위해 원지(P)의 이송구간에 회전가능하게 설치되어 원지(P)의 코팅면을 가열하며 가압하도록 구성된다. 또한, 상기 롤러(10)는 열을 공급받기 위한 히터(20)를 그 내측에 수용하기 위해 회전축(11)을 중심으로 방사상 다수개의 결합홈(12)이 형성된다. 이 때, 상기 결합홈(12)은 롤러(10)의 길이방향에 대응하여 길게 형성되며 이 길이는 히터(20)의 길이와도 대응된다.The roller 10 is rotatably installed in the transfer section of the paper (P) to perform the coating is configured to heat and press the coating surface of the paper (P). In addition, the roller 10 has a plurality of radially engaging grooves 12 are formed around the rotating shaft 11 to accommodate the heater 20 for receiving heat therein. At this time, the coupling groove 12 is formed long corresponding to the longitudinal direction of the roller 10 and this length also corresponds to the length of the heater 20.

상기 히터(20)는 롤러(10)의 회전축(11)을 중심으로 방사상 다수개 형성된 결합홈(12)에 롤러(10)의 삽입되어 설치된다. 이와 같은 히터(20)는 결합홈(12)에 끼워져 히터(20)의 외면이 결합홈(12)의 내주면에 밀착된 상태를 유지하여 롤러(10)가 히터(20)에서 열을 직접 공급받는 형태의 구성이 된다.The heater 20 is installed by inserting the roller 10 in the coupling groove 12 formed in a plurality of radially around the rotating shaft 11 of the roller 10. The heater 20 is inserted into the coupling groove 12 to maintain the outer surface of the heater 20 in close contact with the inner peripheral surface of the coupling groove 12 so that the roller 10 receives heat directly from the heater 20. It becomes the structure of the form.

이와 같은 구성에 의해 상기 히터(20)에서 발생된 열은 롤러(10)에 최대화된 열전도율로 공급될 수 있게 된다. 이 때, 히터(20)는 후술할 전기히터 외에도 고온의 증기로 열을 전달하는 흡사 보일러 시스템 형태의 스팀히터를 적용하여 구성될 수도 있다.By such a configuration, the heat generated by the heater 20 can be supplied to the roller 10 at the maximum thermal conductivity. In this case, the heater 20 may be configured by applying a steam heater in the form of a similar boiler system to transfer heat to a high temperature steam in addition to the electric heater to be described later.

추가하여, 상기 히터(20)는 외부의 전기 전원을 공급받아 코일(21)이 발열되는 전기히터로 적용함이 바람직하다. 이와 같은 구성에서 상기 코일(21)은 롤러(10)의 원지(P)와 접촉되는 작업구간(S1)과 원지(P)가 접촉되지 않는 비작업구간(S2)에 대해 상이한 조밀도로 권선된 배치를 갖는다.In addition, the heater 20 is preferably applied to an electric heater in which the coil 21 generates heat by receiving external electric power. In such a configuration, the coil 21 is disposed to be wound at different densities for the work section S1 in contact with the base paper P of the roller 10 and the non-working section S2 in which the base paper P is not in contact. Has

즉, 상기 코일(21)은 롤러(10)의 작업구간(S1)에 대응하는 길이방향의 구간이 높은 조밀도로 권선되고, 비작업구간(S2)에 대응하는 길이방향의 구간에서는 코일(21)이 없도록 길이설정을 하거나 전원의 입력단부의 구간에서는 코일(21)을 최대한 낮은 조밀도로 권선하도록 구성된다.That is, the coil 21 is wound in the longitudinal direction corresponding to the work section S1 of the roller 10 with high density, and the coil 21 in the lengthwise section corresponding to the non-work section S2. The length is set so that the coil 21 is wound at the lowest density in the section of the input end of the power source.

따라서, 상기 작업구간(S1)에 대응하는 코일(21)의 높은 조밀도 권선구간은 목적하는 온도의 열을 발생시킬 수 있게 되며, 비작업구간(S2)에 대응하는 코일(21)의 권선구간은 열이 발생되지 않거나 낮은 조밀도의 권선에 의해 최소한의 온도로 발열되어 롤러(10)와 인접한 이송롤러(F)의 파손을 방지하게 된다.Therefore, the high-density winding section of the coil 21 corresponding to the work section S1 can generate heat of a desired temperature, and the winding section of the coil 21 corresponding to the non-work section S2. Silver does not generate heat or is heated to a minimum temperature by the winding of low density to prevent breakage of the transfer roller F adjacent to the roller 10.

상기 구성에 관련하여, 상기 히터(20)는 롤러(10)의 작업구간에 대응하는 코일(21)의 높은 조밀도 권선구간에서의 조밀도도 이상적으로 배치할 수 있게 된다. 이는 롤러(10)의 작업구간(S1)에 걸쳐 전구간이 균일한 열을 공급할 수 있도록 한 구성이다.In relation to the above configuration, the heater 20 can also ideally arrange the density in the high density winding section of the coil 21 corresponding to the working section of the roller 10. This configuration is such that the entire section can supply uniform heat over the work section S1 of the roller 10.

이를 위해, 상기 롤러(10)의 작업구간(S1)과 대응하는 코일(21)의 길이방향 구간은 전원이 입력되는 측부를 기준으로 그 타측으로 점차 높은 조밀도로 배치되 도록 권선되어 구성된다.To this end, the longitudinal section of the coil 21 corresponding to the working section (S1) of the roller 10 is configured to be wound so as to be gradually disposed to the other side with respect to the side on which power is input.

따라서, 상기와 같이 구성된 코일(21)의 권선배치에 의해 롤러(10)의 전 작업구간(S1)은 균일하게 발열되어 원지(P) 상의 코팅면도 보다 균일하게 작업되어 고급화된 제품이 완성될 수 있게 된다.Therefore, the entire work section S1 of the roller 10 is uniformly generated by the winding arrangement of the coil 21 configured as described above, so that the coated surface on the base paper P is more uniformly worked, thereby completing an advanced product. Will be.

동시에, 상기 히터(20)는 외부의 전기 전원을 공급하는 파워서플라이(30)와 전기적으로 연결되어 구성된다. 이 때, 상기 전원이 공급되기 위해서는 회전체와 고정체를 전기적으로 연결하기 위한 컨넥팅 구성으로 슬립링(31)이 적용되어 구성된다.At the same time, the heater 20 is configured to be electrically connected to the power supply 30 for supplying external electric power. At this time, in order to supply the power, the slip ring 31 is applied to the connecting structure for electrically connecting the rotor and the fixed body.

상기 슬립링(31)은 히터(20)와 파워서플라이(30)의 전원공급라인에 개재되어 구성되며, 도면에서는 다수개 장착된 히터(20)가 각 극성별로 병렬연결되어 양극, 음극의 두 극성의 전원공급라인이 인출된 구성된 상태를 예시한다.The slip ring 31 is configured to be interposed in the power supply line of the heater 20 and the power supply 30, and in the drawing, a plurality of heaters 20 are connected in parallel for each polarity, so that the two polarities of the positive electrode and the negative electrode are negative. Illustrates the configured state that the power supply line is drawn out.
