본 발명은 패드의 무늬성형장치에 관한 것으로서, 더욱 상세하게는 양각 또는 음각으로 성형된 성형부를 갖는 성형벨트에 의해 패드의 일면 또는 양면에 무늬 나 돌기 등이 성형될 수 있도록 하여 생산성 향상은 물론, 생산단가의 절감효과를 가져올 수 있는 패드의 무늬성형장치에 관한 것이다.The present invention relates to a pattern forming apparatus of a pad, and more particularly, by using a molding belt having a molded part embossed or engraved, a pattern or a protrusion may be molded on one or both sides of the pad, thereby improving productivity. The present invention relates to a pad molding apparatus that can reduce the production cost.

일반적으로, 고무재질로 이루어진 패드는, 자동차의 실내깔판이나 욕실의 슬립방지판 또는 각종 슬립방지패드로 사용되고 있는 바, 이러한 패드의 일면 또는 양면에는 슬립을 방지함과 동시에 패드의 외관을 미려하게 연출하기 위한 다양한 무늬, 문양 등이 성형되어 있다.In general, a pad made of rubber material is used as an interior pallet of a car, a slip prevention plate of a bathroom, or various slip prevention pads, and one or both sides of the pad prevent slip and at the same time produce a beautiful appearance of the pad. Various patterns, patterns and the like are molded.

종래, 패드의 일면 또는 양면에 무늬를 성형하는 방법은, 도 1에 도시된 바와 같이 외주면에 음각 또는 양각으로 성형된 성형부(1a)를 갖는 성형가압롤러(1)와, 상기 성형가압롤러(1)의 일측에 구비되는 지지롤러(2)에 의해 패드(3)의 일면 또는 양면에 다양한 무늬(3a)를 성형하고 있다.Conventionally, a method of molding a pattern on one or both sides of the pad, as shown in Figure 1, the molding pressing roller (1) having a molded portion (1a) formed in an intaglio or embossed on the outer peripheral surface, and the pressing roller ( Various patterns 3a are molded on one side or both sides of the pad 3 by the support rollers 2 provided on one side of 1).

즉, 상기 성형가압롤러(1)와 지지롤러(2) 사이로 패드(3)를 성형하기 위한 성형물(3b)이 지나도록 하고 상기 성형물(3b)이 지나는 과정에서 상기 성형가압롤러(1)의 외주면에 성형된 성형부(1a)가 성형물(3b)의 일면 또는 양면을 가압함으로써 성형부(1a)의 형상과 동일한 형상의 무늬가 성형되도록 하고 있다.That is, the molding 3b for molding the pad 3 passes between the molding pressing roller 1 and the supporting roller 2 and the outer peripheral surface of the molding pressing roller 1 in the course of passing the molding 3b. The molded part 1a molded into the mold presses one surface or both sides of the molded product 3b so that a pattern having the same shape as that of the molded part 1a is molded.

그러나, 이와 같이 성형가압롤러에 의해 패드의 일면 또는 양면에 무늬를 성형하는 방법은, 생산성 저하와 함께 생산단가의 증대를 가져오고 또한, 패드의 일면 또는 양면에 성형되는 무늬의 반복됨이 좁게 이루어짐으로써, 패드의 외관을 미려하게 연출하지 못하고 줄무늬나 물결무늬 등과 같은 단순한 무늬만을 성형할 수 밖에 없는 문제점이 있다.However, the method of molding the pattern on one side or both sides of the pad by the molding press roller in this way, the productivity is reduced and the production cost increases, and the repeated pattern of the pattern formed on one side or both sides of the pad is narrowed. There is a problem in that only a simple pattern such as stripes or wave patterns can be molded without a beautiful appearance of the pad.

다시 말해, 상기 성형가압롤러에 형성된 성형부에 의해 성형되는 패드의 무 늬는, 롤러의 특성상 성형가압롤러가 360ㅀ 회전되었을 때 하나의 무늬패턴이 형성되기 때문에, 동일한 무늬가 반복적으로 패드의 일면 또는 양면에 성형될 수 밖에는 없는 바, 이 때, 성형가압롤러의 외주면 원주율에 따라 무늬의 패턴이 반복적으로 성형되기 때문에 패드의 일면 또는 양면에 단순한 형태의 무늬가 성형되는 문제점이 있다.In other words, since the pattern of the pad formed by the forming portion formed on the pressurizing roller is one pattern pattern when the pressurizing roller is rotated 360 ° due to the characteristics of the roller, the same pattern is repeatedly formed on one surface of the pad. Or it can not only be molded on both sides, at this time, since the pattern of the pattern is repeatedly formed according to the circumference of the outer circumferential surface of the molding press roller, there is a problem that a simple pattern is formed on one side or both sides of the pad.

따라서, 연속적인 무늬 형상을 위해 상기 성형가압롤러에 의해 성형되는 무늬는 대개 줄무늬나 물결무늬와 같은 단순한 무늬가 주를 이루고 있는 실정이다.Therefore, the pattern formed by the molding press roller for the continuous pattern shape is usually a situation that is mainly composed of simple patterns such as stripes or wave pattern.

뿐만 아니라, 상기와 같이 성형가압롤러의 경우, 롤러의 외주면에 무늬부를 형성하기 위한 조각작업이 어렵고 이에 따른 비용이 매우 고가임으로써 생산단가의 증대를 가져오는 문제점이 있다.In addition, in the case of the molding press roller as described above, there is a problem that the engraving work for forming the pattern portion on the outer peripheral surface of the roller is difficult and the cost is very expensive, thereby increasing the production cost.

더욱이, 다른 무늬를 성형하고자 할 경우에는 성형가압롤러 전체를 교체하여야 함으로써, 작업효율성이 크게 저하되는 문제점이 있다.In addition, when the other pattern is to be molded, there is a problem in that the work efficiency is greatly reduced by replacing the entire molding press roller.

본 발명은 전술한 종래 패드의 일면 또는 양면에 무늬나 문양 및 슬립방지부를 롤러에 의해 성형함에 있어서 야기되는 문제점들을 해결하기 위해 안출된 것으로, 일면에 무늬를 성형하기 위한 성형부가 형성된 무늬성형벨트와, 이 무늬성형벨트와 접하는 지지벨트를 구비하되, 상기 지지벨트가 접하는 무늬성형벨트의 일측에 열가압드럼을 구비하여, 고무재질의 가공물이 상기 무늬성형벨트와 지지벨트를 지나는 과정에서 열가압드럼에 의해 무늬가 열가압성형되도록 할 뿐만 아니라, 장폭의 무늬성형벨트의 일면에 형성된 무늬부에 의해 다양한 형상의 무늬를 가압성형할 수 있고, 회전되는 벨트에 의해 무늬가 성형됨으로써 벨트의 교체작업이 용이하여 다양한 무늬를 성형할 수 있는 패드의 무늬성형장치를 제공함에 그 목적이 있다.The present invention has been made to solve the problems caused by forming the pattern or pattern and the slip-resistant portion by the roller on one or both sides of the conventional pad described above, and a patterned belt formed with a molded part for forming a pattern on one surface; A support belt is in contact with the pattern-forming belt, and the support belt is provided with a pressure-pressing drum on one side of the pattern-forming belt, so that a rubber-like workpiece passes through the pattern-forming belt and the support belt.

도 2는 본 발명인 패드의 무늬성형장치의 구성에 의해 패드의 일면에 무늬가 성형되는 것을 나타낸 구성도이고, 도 3은 본 발명인 패드의 무늬성형장치의 다른 실시예에 의해 패드의 양면에 무늬가 성형되는 것을 나타낸 구성도이다.Figure 2 is a block diagram showing a pattern formed on one side of the pad by the configuration of the pattern forming apparatus of the present invention, Figure 3 is a pattern on both sides of the pad according to another embodiment of the pattern forming apparatus of the present invention It is a block diagram which shows what is shape | molded.

도시된 바와 같이 본 발명인 패드의 무늬성형장치는, 열매체에 의해 가열되는 열가압드럼(11)과, 상기 열가압드럼(11)의 타측에 위치되는 연동롤러(12)와, 상기 열가압드럼(11)과 연동롤러(12)의 외주면에 내측 양단이 각각 권회되고 일면에 무늬부(10a)가 길이방향으로 형성된 무늬성형벨트(10)와, 상기 열가압드럼(11)의 양측에 구비되는 2개의 지지롤러(21)(22)와, 상기 2개의 지지롤러(21)(22)의 타측 중앙에 위치되는 텐션롤러(23)와, 상기 2개의 지지롤러(21)(22)와 텐션롤러(23)의 외주면에 내측이 각각 권회되고 상기 열가압드럼(11)에 권회된 무늬성형벨트(10)와 일측이 밀접되는 지지벨트(20)로 구성된다.As shown, the pad forming apparatus of the present invention includes a thermopressing drum 11 heated by a heat medium, an interlocking roller 12 located on the other side of the thermopressing drum 11, and the thermopressing drum ( 11) and both of the inner side ends are wound on the outer circumferential surface of the interlocking roller 12 and the pattern forming belt 10 having a pattern portion 10a formed on one surface thereof in the longitudinal direction, and two provided on both sides of the heat pressurizing drum 11. Two support rollers 21 and 22, a tension roller 23 located at the center of the other side of the two support rollers 21 and 22, and the two support rollers 21 and 22 and a tension roller ( The inner circumference of the outer circumferential surface of the 23) is composed of a support belt 20 in which one side is in close contact with the patterned belt 10 wound on the heat pressurizing drum 11.

상기 무늬성형벨트(10)는 열에 강한 합성수지인 테프론(teflon)벨트로 이루어질 수 있다.The patterned belt 10 may be made of a teflon belt which is a synthetic resin resistant to heat.

또한, 상기 2개의 지지롤러(21)(22)와 텐션롤러(23)에 각각 권회되는 상기 지지벨트(20)는 금속재질로 이루어질 수 있다.In addition, the support belts 20 respectively wound on the two support rollers 21 and 22 and the tension roller 23 may be made of a metal material.

상기 텐션롤러(23)는 상기 2개의 지지롤러(21)(22)에 대해 일측 또는 타측으로 그 위치가 가변될 수 있도록 구성될 수 있는 것으로, 이에 따라, 상기 2개의 지지롤러(21)(22)와 텐션롤러(23)에 권회된 상기 지지벨트(20)는 그 장력이 조절된다.The tension roller 23 may be configured such that its position may be changed to one side or the other side with respect to the two support rollers 21 and 22, and thus, the two support rollers 21 and 22. ) And the support belt 20 wound around the tension roller 23 is adjusted in tension.

따라서, 상기 열가압드럼(11)에 밀접되는 지지벨트(20)의 장력에 의해 열가압드럼(11)의 외측에 권회된 상기 무늬성형벨트(10)가 상기 지지벨트(20)와 밀착될 수 있다.Therefore, the patterned belt 10 wound on the outside of the thermo-pressure drum 11 may be in close contact with the support belt 20 by the tension of the support belt 20 in close contact with the thermo-pressure drum 11. have.

이는, 상기 무늬성형벨트(10)와 지지벨트(20)가 서로 밀착되지 않아 가압력이 저하될 경우에, 이들 사이를 통과하는 가공물인 고무패드의 일면에 발포현상이 발생되어 무늬가 제대로 성형되지 않기 때문에 상기 무늬성형벨트(10)와 지지벨트(20)는 항상 긴장된 상태로 서로 밀착되는 것이 바람직하다.This means that when the pattern forming belt 10 and the support belt 20 are not in close contact with each other and the pressing force is reduced, foaming occurs on one surface of the rubber pad, which is a workpiece passing therebetween, so that the pattern is not formed properly. Therefore, the pattern forming belt 10 and the support belt 20 is preferably in close contact with each other in a tense state.

상기 열가압드럼(11)에 열을 전달하는 열매체는, 수증기나 히터 등 다양한 종류의 열전달수단을 이용할 수 있다.As the heat medium for transferring heat to the heat pressurizing drum 11, various kinds of heat transfer means such as steam or a heater may be used.

상기와 같이 구성된 본 발명인 패드의 무늬성형장치는, 상기 일측의 지지롤러(21)로부터 공급되는 가공물(40)이 상기 열가압드럼(11)에 위치될 경우, 상기 열가압드럼(11)에 권회된 무늬성형벨트(10)와 상기 열가압드럼(11)의 일측에 위치되어 상기 무늬성형벨트(10)에 밀착되는 지지벨트(20)에 의해 가압되고, 이에 따라, 상기 열가압드럼(11)으로부터 발생되는 가압열에 의해 상기 무늬성형벨트(10)의 무늬부(10a)가 상기 가공물(40)의 일면을 가압함으로써 상기 무늬성형벨트(10)의 무 늬부(10a)와 동일한 형상의 무늬(41)가 음각 또는 양각으로 성형된다.The pattern forming apparatus of the present invention configured as described above, when the workpiece 40 supplied from the support roller 21 of the one side is located in the thermopressing drum 11, it is wound on the thermopressing drum 11. The pressing belt is positioned on one side of the pattern forming belt 10 and the heat pressurizing drum 11 and is pressed by the support belt 20 in close contact with the pattern forming belt 10, and thus, the heat pressurizing drum 11 The pattern portion 10a of the pattern forming belt 10 presses one surface of the workpiece 40 by the heat generated from the pattern 41 to have the same shape as the groove portion 10a of the pattern forming belt 10. ) Is indented or embossed.

이와 같은 방법에 의해 계속적으로 공급되는 가공물(40)의 표면에 상기 무늬성형벨트(10)의 무늬부(10a)와 동일한 형상의 무늬(41)가 성형되는 바, 상기 무늬성형벨트(10)가 열가압드럼(11)과 연동롤러(12)에 의해 계속적으로 일방향 회전함으로써 무늬성형벨트(10)의 길이방향으로 형성된 무늬부(10a)에 의해 상기 가공물(40)의 표면에 연속적인 무늬가 성형된다.The pattern 41 having the same shape as the pattern portion 10a of the pattern forming belt 10 is formed on the surface of the workpiece 40 which is continuously supplied by the method, and the pattern forming belt 10 is The continuous pattern is formed on the surface of the workpiece 40 by the pattern portion 10a formed in the longitudinal direction of the pattern forming belt 10 by continuously rotating in one direction by the heat pressurizing drum 11 and the interlocking roller 12. do.

따라서, 연속적인 무늬가 자연스럽게 성형될 수 있기 때문에, 종래 줄무늬나 물결무늬는 물론 다양한 종류의 무늬를 형성할 수 있다.Therefore, since the continuous pattern can be naturally formed, it is possible to form various types of patterns as well as conventional stripes and wave patterns.

또한, 패드의 일면을 성형하는 무늬를 벨트의 일면에 성형가공하기 때문에, 무늬를 성형가공하는 작업이 수월하여 종래 성형가압롤러의 표면 즉 외주면에 무늬를 성형가공하는 작업에 비해 단가가 절감될 수 있어 생산단가의 절감을 유도한다.In addition, since the pattern for forming one side of the pad is molded on one side of the belt, the process of forming the pattern is easy, and thus the unit cost can be reduced as compared to the process of forming a pattern on the surface of the conventional pressing roller, that is, the outer circumferential surface. This leads to a reduction in production cost.

뿐만 아니라, 패드의 일면에 새로운 무늬를 성형하고자 할 경우에는, 상기 무늬성형벨트(10)를 풀고 다른 무늬가 형성된 새로운 무늬성형벨트를 상기 열가압드럼(11)과 연동롤러(12)에 권회시켜 작업할 수 있음으로써, 작업성이 향상된다.In addition, when a new pattern is to be molded on one surface of the pad, the pattern forming belt 10 is unwound and a new pattern forming belt in which another pattern is formed is wound on the thermal pressure drum 11 and the interlocking roller 12. By being able to work, workability improves.

도 3은 본 발명인 패드의 무늬성형장치의 다른 실시예를 나타낸 구성도로서, 상기 텐션롤러(23)의 일측에는 보조텐션롤러(31)가 더 구비되고, 상기 보조텐션롤러(31)와 상기 2개의 지지롤러(21)(22)에 각각 권회된 보조성형벨트(30)가 상기 지지벨트(20)의 외측부에 더 구비된다.Figure 3 is a block diagram showing another embodiment of the pattern forming apparatus of the present invention, one side of the tension roller 23 is further provided with an auxiliary tension roller 31, the auxiliary tension roller 31 and the second The auxiliary molding belt 30 wound around the two support rollers 21 and 22 is further provided on the outer side of the support belt 20.
