Description

미끄럼 방지판을 지닌 쟁반의 제조방법 {Method for manufacturing a tray having anti-slippery plate}Method for manufacturing a tray with anti-slip plate {Method for manufacturing a tray having anti-slippery plate}

본 발명은 쟁반의 제조방법에 관한 것으로서, 좀더 상세하게는 바닥면과 저면에서 이중으로 미끄럼을 방지하는 쟁반을 성형함에 있어 전용의 시스템으로 안정된 품질과 생산성을 유지할 수 있는 미끄럼 방지판을 지닌 쟁반의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a tray, and more particularly, in forming a tray that prevents slipping on the bottom and bottom in a double way, a tray having a non-slip plate capable of maintaining stable quality and productivity with a dedicated system. It relates to a manufacturing method.

쟁반은 음식물이나 용기를 이동하는 용도로 사용되는 주방기기로서 대체로 장방형이나 원형의 판형태를 지니고 목재, 금속, 합성수지 등의 다양한 소재가 사용된다. 그중 합성수지 소재의 쟁반은 저렴하기 때문에 가장 흔하게 사용되지만 용기가 미끄러지기 쉬우므로 바닥에 천, 레이스, 고무판, 연질합성수지판, 발포 합성수지시트 등으로 된 미끄럼 방지판을 까는 경우가 많다.Trays are kitchen appliances used to move food or containers, and generally have a rectangular or circular plate shape, and various materials such as wood, metal, and synthetic resin are used. Among them, synthetic resin trays are the most commonly used because they are inexpensive, but since containers are slippery, slippers made of cloth, lace, rubber plates, soft synthetic resin plates, foamed synthetic resin sheets, etc. are often placed on the floor.

그러나 쟁반을 사용하는 중에 미끄럼 방지판이 이탈되거나 분실되기 쉬우므로 접착제로 붙여야 하는 번거로움이 있고 반복적으로 고열을 받으면서 접착력이 약한 부분에서 변형되어 미관상 나쁘다. 이를 방지하기 위해 미끄럼 방지판을 인서트 성형한 쟁반이 제안되기도 하는데, 접착제를 도포한 것에 비하여 전체적으로 접착력이 고르게 유지되어 내구성이 좋다.However, since the non-slip plate is easy to break out or lost while using the tray, it is cumbersome to attach it with adhesive, and it is deteriorated aesthetically because it is deformed at a weak adhesive strength under repeated high heat. In order to prevent this, a tray in which an anti-slip plate is insert-molded is proposed, but the adhesive force is maintained evenly as a whole compared to the application of the adhesive, so that durability is good.

도 1은 종래의 쟁반 제조공정을 순차적으로 나타내는 도식도가 도시된다.1 is a schematic view showing a conventional tray manufacturing process sequentially.

우선 압출기(12)에서 고무 소재를 압출하여 부호 11'와 같은 시트형태의 고무판을 연속적으로 생성하고, 다음으로 치수에 맞도록 재단하여 고무판(11)을 완성하고, 다음으로 사출기(14)의 금형에 고무판(11)을 장입한 상태로 용융된 경질 합성수지를 투입하고, 마지막으로 고무판(11)이 인서트된 쟁반(10)을 이젝트하여 후처리하는 과정을 거친다.First, the rubber material is extruded from the extruder 12 to continuously produce a sheet-shaped rubber sheet as indicated by reference numeral 11 ', and then cut to fit the dimension to complete the rubber sheet 11, and then the mold of the injection machine 14. The molten hard synthetic resin is poured into the rubber plate 11 in the state of charging the rubber plate 11, and finally, the rubber plate 11 is ejected from the tray 10 into which the rubber plate 11 is inserted.

이와 같은 시스템에 의하면 상하로 작동하는 수직식 사출기를 사용해야 하므로 설치공간이 커지고 상대적으로 융점이 낮은 고무판의 성형성을 고려하여 고형화하게 되고 이에 따라 마찰계수가 감소되어 사용시 미끄럼이 발생할 우려가 있다. 그리고 쟁반(10)의 한 면(바닥면)에만 고무판(11)이 형성되어 식탁 등에 올려놓을때 저면에서 미끄럼이 발생된다. 쟁반(10)의 저면에 돌기(10a)를 형성하여도 경질 합성수지로 접촉하는 한 미끄럼 현상을 피할 수 없게 된다.According to such a system, a vertical injection molding machine operating up and down should be used to increase the installation space and to solidify in consideration of the moldability of the rubber sheet having a relatively low melting point, thereby reducing the friction coefficient, which may cause slippage in use. And the rubber plate 11 is formed only on one side (bottom surface) of the tray 10, the sliding occurs on the bottom when placed on the table. Even if the protrusions 10a are formed on the bottom of the tray 10, the sliding phenomenon cannot be avoided as long as they are in contact with the hard synthetic resin.

또한, 종래의 시스템으로 쟁반(10)의 저면에 다른 소재가 부가되도록 성형하기 곤란하고, 설사 고무판(11)의 일부를 연장하여 고무판(11)의 저면으로 노출시키려 해도 원하는 품질이 유지되지 않고 생산성도 저하된다.In addition, it is difficult to mold other materials to be added to the bottom of the tray 10 by a conventional system, and even if a part of the rubber plate 11 is extended to be exposed to the bottom of the rubber plate 11, the desired quality is not maintained and productivity is maintained. Also deteriorates.

이에 따라 본 발명은 상기한 문제점을 해결하기 위한 것으로서, 바닥면과 저면에서 이중으로 미끄럼을 방지하는 쟁반을 성형함에 있어 전용의 시스템으로 안정된 품질과 생산성을 유지할 수 있는 미끄럼 방지판을 지닌 쟁반의 제조방법을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention is to solve the above problems, the production of a tray having a non-slip plate that can maintain a stable quality and productivity in a dedicated system in forming a non-slip tray at the bottom and bottom Its purpose is to provide a method.

이러한 목적을 달성하기 위해 본 발명은 바닥면과 저면에서 이중으로 미끄럼을 방지하는 쟁반을 성형하는 방법에 있어서: 수평식 사출기로 이루어진 한 쌍의 성형기(15)(25)에 각각 적용하기 위한 금형을 제작하는 제1단계; 상기 일차성형기(15)에 수지원료를 투입하여 다수의 통공(20a)을 지닌 쟁반(20)을 성형하는 제2단계; 및 상기 이차성형기(25)에 상기 쟁반(20)을 인서트하고 고무원료를 투입하여 고무판(21)이 도포된 쟁반(20)을 완성하는 제3단계를 포함하여 이루어지는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a method for forming a non-slip tray at the bottom and the bottom: a mold for each application to a pair of molding machines (15, 25) consisting of a horizontal injection molding machine. A first step of manufacturing; A second step of forming a tray 20 having a plurality of through holes 20a by injecting a water support fee into the primary molding machine 15; And inserting the tray 20 into the secondary molding machine 25 and injecting a rubber material to complete the tray 20 to which the rubber plate 21 is applied.

이때, 상기 제1단계의 금형은 고무원료가 쟁반(20)의 바닥면을 통하여 저면에 4∼5개로 분산되는 지점에 도달되도록 구성된다.At this time, the mold of the first step is configured to reach the point where the rubber raw material is dispersed in four to five on the bottom through the bottom surface of the tray (20).

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 쟁반 제조공정을 순차적으로 나타내는 도식도, 도 3은 본 발명에 따른 쟁반이 성형되는 금형을 나타내는 단면도이다.Figure 2 is a schematic diagram showing a tray manufacturing process according to the present invention, Figure 3 is a cross-sectional view showing a mold in which the tray according to the present invention.

본 발명은 바닥면과 저면에서 이중으로 미끄럼을 방지하는 쟁반을 성형하는 방법에 관련된다. 쟁반의 소재로 사용되는 멜라민수지, ABS수지, PP수지 등의 경질 합성수지는 각종 물성 측면에서 차이가 있기는 하지만 모두 마찰계수가 작아 바닥면과 저면에서 미끄럼이 방지되지 않는다. 여기서 바닥면은 음식물이나 용기를 올려놓는 부분(상면)을 말하며 저면은 테이블에 접촉하는 면을 의미한다.The present invention relates to a method of forming a non-slip tray at double and bottom surfaces. Hard synthetic resins such as melamine resin, ABS resin, and PP resin, which are used as tray materials, are different in terms of their physical properties, but they all have low coefficients of friction and are not prevented from slipping at the bottom and bottom. Here, the bottom surface refers to a portion (top) where food or a container is placed, and the bottom surface refers to a surface in contact with a table.

본 발명의 제1단계에서 수평식 사출기로 이루어진 한 쌍의 성형기(15)(25)에 각각 적용하기 위한 금형을 제작한다. 종래에는 수직식 사출기와 1벌의 금형으로 다목적인 생산이 가능하지만 비교적 대형의 제품에 적절하고 설치공간도 많이 차지한다. 따라서 본 발명에서 소형화가 가능한 수평식 사출기가 제안된다. 통상적인 철/비철금속의 금형에는 탄소강, 내열강, 공구강이 사용되지만 수지류의 성형에는 성형압에 따라 고압에서 경화한 강이 사용되고 저압에서 구리합금이 사용된다. 정밀한 모양으로 성형하려면 베릴륨 구리의 금형을 이용할 수도 있다. 본 발명에서 한 쌍의 성형기(15)(25)에 적용되는 금형은 소재를 달리할 수 있으며 어느 경우에나 크롬도금을 하면 내마모성이 향상된다.In the first step of the present invention to produce a mold for applying to each of a pair of molding machines (15, 25) consisting of a horizontal injection molding machine. Conventionally, multi-purpose production is possible with a vertical injection molding machine and a single mold, but it is suitable for a relatively large product and takes up a lot of installation space. Therefore, in the present invention, a horizontal injection molding machine capable of miniaturization is proposed. Carbon steel, heat-resistant steel, and tool steel are used for conventional iron / nonferrous metal molds, but hardened steel at high pressure is used for molding resins, and copper alloy is used at low pressure. Molds of beryllium copper can also be used to form precise shapes. In the present invention, the mold applied to the pair of molding machines 15 and 25 may have different materials, and in any case, the chromium plating improves the wear resistance.

이때, 상기 제1단계의 금형은 고무원료가 쟁반(20)의 바닥면을 통하여 저면에 4∼5개로 분산되는 지점에 도달되도록 구성된다. 종래와 마찬가지로 쟁반(20)의바닥면에 고무판(21)이 개재되어 미끄럼을 방지하는 구성에 있어 고무판(21)은 쟁반(20)에 함몰되어 동일한 높이를 유지한다. 반면 고무판(21)이 쟁반(20)을 통과하여 저면에서 노출되어 또 다른 미끄럼 방지의 기능을 수행한다. 저면에 노출되는 부분은 쟁반이 테이블에서 미끄러지지 않도록 4∼5개소이면 충분하다.At this time, the mold of the first step is configured to reach the point where the rubber raw material is dispersed in four to five on the bottom through the bottom surface of the tray (20). As in the prior art, the rubber plate 21 is interposed in the bottom surface of the tray 20 to prevent slippage. The rubber plate 21 is recessed in the tray 20 to maintain the same height. On the other hand, the rubber plate 21 passes through the tray 20 and is exposed at the bottom to perform another non-slip function. Four to five places should be enough to prevent the tray from slipping on the table.

본 발명의 제2단계에서 상기 일차성형기(15)에 수지원료를 투입하여 다수의 통공(20a)을 지닌 쟁반(20)을 성형한다. 이때의 금형은 이차성형기(25)의 금형에 비해 고무판(21) 만큼 캐비티의 용적이 줄어든 구조이고, 통공(20a)을 형성하기 위한 복수의 핀이 캐비티에 돌출된다. 일차성형기(15)의 호퍼로 수지원료를 투입하면 용융과 동시에 노즐을 통해 캐비티에 충진되고 금형을 개방하여 이젝트하면 다수의 통공(20a)을 지닌 쟁반(20)이 형성된다. 물론 다수의 통공(20a)이 있기 때문에 이대로는 쟁반으로 사용하기 곤란하다.In the second step of the present invention, a water support fee is added to the primary molding machine 15 to form a tray 20 having a plurality of through holes 20a. At this time, the mold has a structure in which the volume of the cavity is reduced by the rubber plate 21 as compared with the mold of the secondary molding machine 25, and a plurality of pins for forming the through hole 20a protrude into the cavity. When the water support material is introduced into the hopper of the primary molding machine 15, the tray 20 having a plurality of through holes 20a is formed by filling the cavity through the nozzle and ejecting the mold by ejecting the mold. Of course, because there are a plurality of through holes (20a) it is difficult to use as a tray.

본 발명의 제3단계에서 상기 이차성형기(25)에 상기 쟁반(20)을 인서트하고 고무원료를 투입하여 고무판(21)이 도포된 쟁반(20)을 완성한다. 고무원료는 적당한 유연성과 마찰계수를 갖는 합성고무, 천연고무라텍스, 실리콘 등이 사용되나 연질PVC를 사용할 수도 있다. 특히 실리콘 고무는 내열성이 좋고 고강도이며 수축율이 작고 성형과정에서 이형성도 양호하여 바람직하다. 쟁반(20)을 금형에 장입한 상태로 용융된 고무원료를 투입하면 노즐을 통하여 캐비티가 충진되고 냉각이 진행되는 동안 가소성에 의해 경화된다.In the third step of the present invention, the tray 20 is inserted into the secondary molding machine 25 and a rubber material is added to complete the tray 20 to which the rubber plate 21 is applied. The rubber raw material is synthetic rubber, natural rubber latex, silicone, etc., which have moderate flexibility and coefficient of friction. However, soft PVC may be used. In particular, silicone rubber is preferred because it has good heat resistance, high strength, small shrinkage ratio, and good releasability during molding. When the molten rubber raw material is introduced while the tray 20 is loaded into a mold, the cavity is filled through the nozzle and cured by plasticity while cooling is performed.

도 3에서, 노즐로 투입되는 고무원료는 중앙의 런너(25a)를 통하여 쟁반(20)의 바닥면에서 상하로 진행되는 동시에 통공(20a)을 통하여 저면에 이른다. 저면에도달되는 고무원료는 리벳의 머리 모양으로 고화되어 돌기(21a)를 형성한다. 이에 따라 쟁반(20)의 바닥면과 저면에서 동시에 미끄럼이 방지될 뿐 아니라 고무판(21)의 결합력이 증대되어 이탈되지 않는다.In FIG. 3, the rubber raw material introduced into the nozzle proceeds up and down at the bottom of the tray 20 through the central runner 25a and reaches the bottom through the through hole 20a. The rubber raw material reaching the bottom surface is solidified in the shape of the head of the rivet to form the projection 21a. Accordingly, not only slip is prevented at the bottom and bottom of the tray 20 at the same time, but also the bonding force of the rubber plate 21 is increased and is not separated.

이때, 고무를 투입하여 성형하는 과정에서 다량의 가스가 발생되므로 금형에 가스배출구를 구비한다. 그리고 성형후 이젝트시 고무판(21)의 분리가 용이하도록 이형제를 사용할 수도 있다.At this time, since a large amount of gas is generated in the process of molding the rubber is provided with a gas outlet in the mold. And release agent may be used to facilitate the separation of the rubber plate 21 during ejection after molding.

이와 같이 본 발명의 시스템은 2벌의 성형기(15)(25)와 금형을 기반으로 하는 전용의 공정을 사용하므로 다른 용도의 제품을 생산하는 유연성은 부족하지만 본 발명의 목적에 부합하는 쟁반의 생산에는 최적이다.As such, the system of the present invention uses a dedicated process based on two molding machines (15) and (25) molds, but lacks the flexibility of producing products for other uses, but produces trays consistent with the object of the present invention. Is optimal.

이상의 구성 및 작용에 따르면 본 발명은 바닥면과 저면에서 이중으로 미끄럼을 방지하는 쟁반을 성형함에 있어 전용의 시스템으로 안정된 품질과 생산성을 유지할 수 있는 효과가 있다.According to the above configuration and operation, the present invention has the effect of maintaining stable quality and productivity in a dedicated system in forming a tray to prevent slipping in the bottom and bottom double.

본 발명은 기재된 실시예에 한정되는 것은 아니고, 본 발명의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형할 수 있음은 이 기술의 분야에서 통상의 지식을 가진 자에게 자명하다. 따라서 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
