본 발명은 일체형 구조의 손수레용 타이어 제조방법에 관한 것으로서 더욱 상세히는 사계절의 변화에 관계없이 타이어의 신축성을 유지함으로써 안정된 화물 이송이 되게 함은 물론, 타이어 외주면의 마모현상을 최소화함으로써 손수레의 유지 보수에 소요되는 비용을 대폭 절감시킬 수 있는 손수레용 타이어의 제조 방법에 관한 것이다. The present invention relates to a tire manufacturing method for a trolley with an integrated structure, and more particularly, to maintain a stretch of the tire regardless of the change of the four seasons to ensure a stable cargo transfer, as well as to minimize the wear phenomenon of the tire outer peripheral surface maintenance of the cart The present invention relates to a method for manufacturing a tire for a wheelbarrow, which can greatly reduce the cost.

차량에서 하차하여 근거리로 하차 된 화물(짐)을 운반하는데 주로 사용되는 손수레는 대부분 고무 재질로 제조된 타이어가 장착되어 사용되는데, 이러한 고무 타이어는 딱딱한 표면을 갖는 외피의 내측으로 신축성과 탄성을 구비한 고무 튜브가 내설 되어져 운반의 편리함과 안정감을 제공해준다.Most of the trolleys used for transporting cargo (load) from a vehicle to a short distance are loaded with tires made of rubber material. These rubber tires have elasticity and elasticity inside the shell having a hard surface. One rubber tube is built-in, providing convenience and stability of transportation.

그러나 상기와 같은 구성으로 제조된 손수레용 타이어는 장시간 사용으로 타이어의 외피가 갈라지거나 혹은 그 내설 된 고무 튜브가 펑크 및 마모가 되는 경우가 다반사로 발생 되고 있으며, 사용 환경에 따라 간혹 사용하는 작업장에서는 장시간의 방치로 인해 튜브의 공기압이 약해져 안정된 운반을 제공하지 못하는 경우도 있다.However, a tire for a wheelbarrow manufactured in the above configuration is often caused by long-term use of cracking of the outer skin of the tire or puncture and abrasion of the insulated rubber tube. Due to prolonged neglect, the air pressure in the tubes may be weakened, which may not provide stable transport.

그리고 작업환경이 난해한 환경 즉, 날카로운 금속 가공품이 바닥에 즐비한 작업장에서는 고무튜브가 날카로운 이물질에 의해 펑크가 나면 타이어 자체의 교환 내지는 펑크 난 부분을 보수해야하는 번거로움과 어려움이 있었다.And in an environment where the working environment is difficult, that is, in the workplace with sharp metal workpieces on the floor, when the rubber tube is punctured by a sharp foreign material, there is a hassle and difficulty of replacing the tire itself or repairing the punctured part.

이에 본 발명에서는 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서 타이어의 신축성과 탄성력을 그대로 유지함과 동시에 타이어의 외피와 내설되는 고무튜브를 일체형으로 형성시키되 1회의 성형으로만 제작되도록 함으로서 운반의 편리함과 안정감을 제공함은 물론 손수레의 유지보수에 소요되는 비용을 최소화할 수 있는 손수레용 타이어를 제공함에 그 목적이 있다.In the present invention, to solve the above problems, while maintaining the elasticity and elasticity of the tire as it is, at the same time to form a rubber tube that is integral with the outer shell of the tire and built-in, so as to be produced only in one molding and the convenience of transportation In addition to providing a sense of stability and the purpose of providing a tire for the cart that can minimize the cost of the maintenance of the cart.

상기한 목적을 달성하기 위하여 본 발명에서는 첨부된 각 도면에 의거하여 상세히 설명하면 하기와 같다.In order to achieve the above object, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 일체형 구조의 손수레 타이어 제조공정도이고, 도 2는 본 발명의 기술이 적용된 타이어의 정면도이며, 도 3은 본 발명의 기술이 적용된 타이어의 측단면도로서 본 발명에서 제공하는 일체형 구조의 손수레용 타이어 제조방법은,1 is a manufacturing process diagram of a wheelbarrow tire of an integrated structure according to the present invention, FIG. 2 is a front view of a tire to which the technique of the present invention is applied, and FIG. 3 is a side cross-sectional view of a tire to which the technique of the present invention is applied. Tire manufacturing method for cart of structure,

PVC(염화비닐수지)와 가소제 DOA(디옥틸아디페이트)를 1 : 0.8의 비율(g)로 혼합한 재료를 예열기에서 배합 및 100~110℃까지 예열한 후 미리 제작된 손수레용 타이어 금형틀이 장착된 사출기의 호퍼에 투입하여 1회의 단발성형으로 타이어의 외피와 고무 튜브 없이 일체형으로 형성된 손수레용 타이어가 사출 성형 되게 하는 것을 특징으로 한다.The pre-made trolley tire mold is prepared after mixing PVC (vinyl chloride resin) and plasticizer DOA (dioctyl adipate) in a ratio of 1: 0.8 in a preheater and preheating to 100 ~ 110 ℃. Into the hopper of the mounted injection machine is characterized in that the tire for the wheelbarrow formed integrally without the outer skin and the rubber tube of the tire in one shot molding to be injection molded.

이때 손수레용 타이어(A)의 측면부(10)는 다양한 무늬를 넣을 수 있는데 이는 사출금형 제작시에 동시 제작을 해줌으로써 타이어의 측면부에 무늬를 형성시킬 수 있는 것이다.At this time, the side portion 10 of the tire (A) for the cart can put a variety of patterns, which is to form a pattern on the side of the tire by making a simultaneous production during the injection mold production.

한편 상기와 같은 방법으로 얻어지는 손수레용 타이어는 딱딱한 성질의 PVC(염화비닐수지)에 내한성 · 내광성 · 내열성 · 무독성이 우수하고 점도가 안정된 가소제 DOA(디옥틸아디페이트)에 의해 신축성이 우수할 뿐만 아니라, 마모가 쉽게 되지 않아 장시간 사용에도 전혀 지장이 없는 손수레용 타이어를 제공할 수 있는 것이다.On the other hand, the tire for trolleys obtained by the above method is not only excellent in elasticity by the plasticizer DOA (dioctyl adipate) which is excellent in cold resistance, light resistance, heat resistance, non-toxicity and stable viscosity to PVC (vinyl chloride resin) of hard property In addition, it is not easy to wear and can provide a tire for a cart that does not interfere at all even long time use.

그리고 이러한 타이어는 고무튜브가 전혀 필요 없음에도 불구 하고 탁월한 신축성과 탄성력을 발휘함으로써 지면이 일정하지 않은 환경에서 물품을 이송할 때 매우 안정된 운반환경이 될 수 있도록 하는 것이다.And even though these tires do not require any rubber tube, it exhibits excellent elasticity and elasticity so that it can be a very stable transport environment when transporting goods in a non-uniform environment.

한편 손수레용 타이어를 사출기에서 단발성형으로 완성되게 함으로서 제작에 소요되는 작업공정 및 제작시간을 대폭 절감할 수 있어 대량생산이 가능함은 물론 손수레의 장시간 사용으로 인해 발생 되는 타이어의 마모, 파손으로 인한 작업지연을 미연에 방지할 수 있는 것이다.On the other hand, it is possible to greatly reduce the work process and production time required for the production of the tires for the trolley by the single molding in the injection molding machine, which enables mass production, as well as the work of tire wear and damage caused by the long-term use of the trolley. The delay can be prevented in advance.

상술한 바와 같은 본 발명의 일체형 구조의 손수레용 타이어 제조방법에 의해 제조된 손수레용 타이어는 신축성과 탄성력이 우수하여 여름 및 겨울 등 계절 변화에 관계없이 편리하고 안정된 물품 운반이 될 수 있도록 함은 물론, 튜브가 내설 되지 않아 장시간의 사용에도 마모 및 파손의 염려가 없으며, 사출금형에서 1회의 단발성형으로 완성되기 때문에 제작에 소요되는 작업공정 및 작업시간을 대폭 축소 시킬 수 있어 제작자는 원가절감의 효과를 얻을 수 있고, 실 사용자는 손수레의 사용에 매우 편리함을 제공할 수 있는 효과가 있다.As described above, the wheelbarrow tire manufactured by the wheelbarrow tire manufacturing method of the present invention has excellent elasticity and elasticity, so that it can be carried conveniently and stably regardless of seasonal changes such as summer and winter. There is no fear of abrasion or damage even if it is used for a long time because the tube is not built in. And since it is completed by one-shot molding in injection mold, the work process and work time required for manufacturing can be greatly reduced. It can be obtained, the actual user has the effect that can provide a very convenience to the use of the cart.
