Description
본 발명은 타이어를 제조하는 과정에 있어서, 고무 등의 원재료를 리본형상으로 성형하고 로울러에 감아 타이어의 기본적 형상을 구성하는 성형기에 관한 것으로, 가열되어 소성(塑性)상태가 된 원재료를 정밀한 압출속도조절이 가능하도록 이송스크류(120) 및 피스톤(110)을 이용하여 노즐(150)을 통해 압출하고, 권취각도에 따라 노즐(150)을 회동(回動)할 수 있도록 하여, 원재료의 압출과 성형권취로울러(300)에 감는 작업이 동시에 이루어지도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding machine which forms a basic shape of a tire by molding a raw material such as rubber into a ribbon shape and winding the roller in a process of manufacturing a tire, and precisely extrudes a raw material that has been heated and calcined. Extrusion and molding of the raw material by extruding through the nozzle 150 using the feed screw 120 and the piston 110 to be adjustable, and to rotate the nozzle 150 in accordance with the winding angle. Winding roller 300 is to be made at the same time the work is wound.
고무를 주성분으로 하는 타이어의 제조공정은 타이어의 종류에 따라 세부적인 부분에서 다소 차이가 있으나, 기본적인 제조공정은 원재료를 리본형상으로 성형하여 로울러에 감아 타이어의 기본적인 형상을 구성하는 중간성형공정과, 이를 몰드(Mold)(500)에 넣고 열과 압력을 가함으로써 형체를 완성하고 탄성(彈性)을 가지도록 하는 가황(加黃)성형공정(S20)으로 이루어진다.The manufacturing process of rubber-based tires is somewhat different depending on the type of tire, but the basic manufacturing process is the intermediate molding process of forming the basic shape of the tire by forming raw materials into ribbons and winding them on rollers; This is put into a mold (500), by applying heat and pressure to form a vulcanization (加 黄) molding process (S20) to complete the mold and have elasticity.
이러한 타이어의 제조방법에 있어서 종래의 기술에 의한 개략적인 제조공정이 도 5에 도시되어 있으며, 이를 상세히 설명하면 다음과 같다.In the manufacturing method of such a tire, a schematic manufacturing process according to the related art is shown in FIG. 5, which will be described in detail as follows.
우선, 고무와 각종 첨가제가 혼합된 원재료를 가열하여 소성상태로 만들고 이를 리본모양으로 성형하여 예비권취로울러(390)에 감는 예비권취공정(S11)을 가지게 되며, 이때, 예비권취로울러(390)에 고무리본(400)을 감을 때에는 이형제(離型劑)를 도포하거나 분리용 시트(Sheet)를 함께 감아서 다음 단계인 권취성형공정(S12)시 예비권취로울러(390)에 감긴 고무리본(400)이 원활하게 풀릴 수 있도록 한다.First, a raw material mixed with rubber and various additives is heated to form a firing state, which is shaped into a ribbon, and has a preliminary winding process (S11) wound on a preliminary winding roller 390. At this time, the preliminary winding roller 390 When the rubber ribbon 400 is wound, the rubber ribbon 400 wound on the preliminary winding roller 390 during the winding forming process (S12) by applying a release agent or winding a separating sheet together. This should work smoothly.
예비권취공정(S11)이 완료되면, 권취성형공정(S12)을 통하여 예비권취로울러(390)에 감긴 고무리본(400)을 풀어 성형권취로울러(300)에 권취속도 및 각도를 조절하여 권취함으로써 타이어의 기본적 형상을 구성하게 되며, 이때에는 접착제를 도포하여 권취를 용이하게 하고 구성된 타이어의 형상이 유지되도록 한다.When the pre-winding step (S11) is completed, the tire by unwinding the rubber ribbon 400 wound around the pre-rolling roller (390) through the winding forming step (S12) by adjusting the winding speed and angle to the molding winding roller (300) The basic shape is to be configured, in which case an adhesive is applied to facilitate the winding and to maintain the shape of the configured tire.
타이어의 형상은 단순한 원통형이 아니라, 부분별로 두께가 다르므로, 타이어 성형을 위하여 고무리본(400)을 권취함에 있어서 회전속도 및 회전수를 조절하여 부분별 권취두께를 조절하여야 한다.Since the shape of the tire is not a simple cylindrical shape, the thickness is different for each part, the winding thickness for each part should be adjusted by adjusting the rotation speed and the rotation speed in winding the rubber ribbon 400 to form the tire.
또한, 타이어의 측면부 성형을 위해서는 도 4에서와 같이 일부 경사면을 가지는 성형권취로울러(300)에 권취한후, 이를 가황성형공정(S20)에서 몰드(500)를 통하여 가열 및 가압하여 측면부를 비롯한 전체의 형태를 완성하는 과정을 거치게 되며, 이러한 경사부 권취에 있어서는 고무리본(400)을 공급하는 각도를 성형권취로울러(300)의 경사에 따라 조절하여야 리본이 꼬이거나 끊기지 않고 원활하게 감길 수 있게 된다.In addition, to form the side portion of the tire, as shown in Figure 4 wound on the molding winding roller 300 having a part inclined surface, it is heated and pressurized through the mold 500 in the vulcanization molding process (S20), including the entire side including In the winding of the inclined portion, the angle of supplying the rubber ribbon 400 must be adjusted according to the inclination of the molding winding roller 300 so that the ribbon can be smoothly wound without twisting or breaking. .
타이어를 권취성형하기위해서는 고무리본(400)의 권취속도 뿐 아니라 권취각도를 적절히 조절할 수 있어야 하며, 원재료를 고무리본(400)으로 성형함과 동시에 권취할 경우 권취속도 및 각도의 조절이 어려우므로, 일단 예비권취로울러(390)에 정속(定速), 정각(定角)으로 감은 후, 이를 다시 속도와 각도를 조절하며 성형권취로울러(300)에 감아서 타이어의 기본 형태를 구성하게 된다.In order to winding the tire, the winding angle of the rubber ribbon 400 should be properly adjusted as well as the winding angle. When the raw materials are wound into the rubber ribbon 400 and wound simultaneously, it is difficult to control the winding speed and the angle. Once the winding in the pre-rolling roller 390 at constant speed, fixed angle, and then adjusts the speed and angle again and wound around the molding winding roller 300 to form a basic form of the tire.
권취성형공정(S12)이 완료된 타이어 성형체는 몰드(500)에 넣고 열과 압력을 가하는 가황성형공정(S20)을 통하여 형체가 완성되고 탄성(彈性)을 가지게 되어, 비로소 완제품(900)이 된다.After the winding molding step (S12) is completed, the tire molded body is completed through the vulcanization molding step (S20), which is placed in the mold 500 and applied heat and pressure, and finally has elasticity, resulting in the finished product 900.
이렇듯, 종래의 타이어 제조 과정은 고무리본(400)의 성형과 타이어의 권취성형과정이 동시에 이루어지지 않고 분리되어, 공정이 복잡할 뿐 아니라 작업소요시간도 길어지게 되어 생산성저하는 물론 제조원가상승의 요인으로 작용하였다.As such, the conventional tire manufacturing process is separated without forming the rubber ribbon 400 and the winding forming process of the tire at the same time, which not only makes the process complicated but also increases the time required for the work, thereby lowering the productivity and increasing the manufacturing cost. Acted as.
또한, 이형제나 접착제가 완제품(900)에도 잔류하게되어 타이어의 품질을 저하시키는 원인이 되고, 이형제 및 접착제의 도포과정 또는 타이어 성형과정에서 유독물질인 이들 물질이 유출 및 증발되게 되므로 환경오염을 유발하는 심각한 문제가 있었다. In addition, the release agent or adhesive remains in the finished product 900, which causes the quality of the tire to deteriorate, and these substances which are toxic substances are leaked and evaporated during the application process of the release agent and adhesive or the tire forming process, causing environmental pollution. There was a serious problem.
본 발명은 전술한 문제점을 감안하여 창안한 것으로, 가열되어 소성(塑性)상태가된 원재료를 정밀한 압출속도조절이 가능하도록 이송스크류(120) 및 피스톤(110)을 이용하여 노즐(150)을 통해 압출하고, 권취각도에 따라 노즐(150)을 회동(回動)할 수 있도록 하여, 원재료의 압출과 성형권취로울러(300)에 감는 작업이 동시에 이루어지도록 함으로써, 타이어의 제조공정을 단순화하였다. The present invention was devised in view of the above-described problems, and through the nozzle 150 using the feed screw 120 and the piston 110 to precisely control the extrusion speed of the raw material heated and fired. By extruding and allowing the nozzle 150 to be rotated according to the winding angle, the extrusion process of the raw materials and the winding of the molding winding roller 300 are simultaneously performed, thereby simplifying the tire manufacturing process.
본 발명의 상세한 구조를 첨부된 도면을 통하여 설명하면 다음과 같다.The detailed structure of the present invention will be described below with reference to the accompanying drawings.
도 1에서와 같이, 본 발명은 원재료를 가열하여 소성상태로 만드는 사출실린더(200)및 그 부속장치와, 원재료의 가열상태 및 소성상태를 유지하며 이를 압출하여 고무리본(400)을 성형하는 압출실린더(100) 및 그 부속장치로 구성되어 있다.As shown in Figure 1, the present invention is an injection cylinder 200 and its accessories to heat the raw material to a plastic state, and the extrusion and molding the rubber ribbon 400 by maintaining the heating and plastic state of the raw material and extruding it It consists of the cylinder 100 and its accessories.
사출실린더(200)는 사출스크류(210)가 내장되고, 온수관과 같은 가열수단(201) 및 원재료 공급을 위한 호퍼(202)가 구비된 형태로, 고무제품이나 합성수지제품의 성형시 사용되는 일반적인 형태이다.The injection cylinder 200 has a built-in injection screw 210, a heating means 201 such as a hot water pipe and a hopper 202 for supplying raw materials, and is used in molding rubber products or synthetic resin products. Form.
이러한 사출실린더(200)는 연속적인 성형이 가능한 장점이 있지만, 사출스크류(210)의 회전에 의하여 재료가 밀려나가게 되므로, 사출스크류(210)를 따라 나선형으로 형성된 상대적으로 긴 유로(流路)와 재료의 탄성으로 인하여 사출속도 및 사출량의 정확한 조절이 곤란할 뿐 아니라 제어에 의한 반응속도 또한 매우 느린 단점이 있다.The injection cylinder 200 has the advantage of being capable of continuous molding, but the material is pushed out by the rotation of the injection screw 210, the relatively long flow path (流 路) formed in a spiral along the injection screw 210 and Due to the elasticity of the material, it is difficult to precisely control the injection speed and the injection amount, and the reaction speed by the control is also very slow.
따라서 본 발명에서는 사출된 재료를 일정량 수용하였다가, 이를 피스톤(110)을 통하여 정확한 속도로 압출하는 압출실린더(100)를 사출실린더(200)와 연결하였으며, 상기 피스톤(110)을 왕복시키기 위한 수단으로는 이송스크류(120) 및 이송너트(130)를 설치하여, 이송너트(130)를 회전시킴으로써, 이송스크류(120)가 왕복될 수 있도록 하였다.Therefore, in the present invention, a predetermined amount of the injected material is accommodated, and the extrusion cylinder 100 for extruding the same at an accurate speed through the piston 110 is connected to the injection cylinder 200, and means for reciprocating the piston 110. In order to install the transfer screw 120 and the transfer nut 130, by rotating the transfer nut 130, the transfer screw 120 can be reciprocated.
또한, 사출실린더(200)와 압출실린더(100)가 연결되는 부분에는 체크밸브(220)를 설치하여 압출실린더(100)로부터 사출실린더(200)로의 역류를 방지하도록 하였으며, 압출실린더(100)에도 사출실린더(200)와 마찬가지로 온수관 등의 가열수단(101)을 구비하여, 재료의 소성상태를 유지하기 위한 보온 또는 필요에 따라 재가열이 가능하도록 하였다.In addition, a check valve 220 is installed at a portion at which the injection cylinder 200 and the extrusion cylinder 100 are connected to prevent a backflow from the extrusion cylinder 100 to the injection cylinder 200, and also to the extrusion cylinder 100. Similar to the injection cylinder 200, a heating means 101, such as a hot water pipe, is provided, so that it is possible to insulate for maintaining the plastic state of the material or to reheat as needed.
압출실린더(100)에 내장된 피스톤(110)을 왕복시키시 위한 방법은 크랭크축이나 유압장치 등 다양한 방법을 적용할 수 있으나, 이러한 방법은 왕복거리 및 속도를 정확하게 제어하기가 매우 곤란하며, 특히 유압장치의 경우 유압작동유의 온도에 따라 점도 및 압력이 틀려지고 제어에 따른 반응시간이 소요되므로, 본 발명에서와 같이 정밀한 압출속도의 조절이 필요한 경우에는 적합하지 않다.The method for reciprocating the piston 110 embedded in the extrusion cylinder 100 may be applied to various methods such as a crankshaft or a hydraulic device, but such a method is very difficult to accurately control the reciprocating distance and speed, in particular hydraulic pressure In the case of the device, since the viscosity and pressure are different according to the temperature of the hydraulic fluid and the reaction time is required according to the control, it is not suitable when precise control of the extrusion speed is required as in the present invention.
이송너트(130)는 스크류와 너트 사이에 베어링 역할을 하는 볼(Ball)(131)이 설치된 볼너트(Ball-Nut)를 채택하여, 이송스크류(120)의 원활하고 정확한 구동이 가능하도록 하였다.The transfer nut 130 adopts a ball nut (Ball-Nut) in which a ball 131 serving as a bearing is installed between the screw and the nut, thereby enabling smooth and accurate driving of the transfer screw 120.
이송너트(130)는 중공구동축(141)에 의하여 구동모터(140)에 연결되게 되고, 일단이 피스톤(110)에 연결 고정된 이송스크류(120)의 타 단부는 이송너트(130)를 통과하여 중공구동축(141) 내부로 수납되게 된다. The conveying nut 130 is connected to the driving motor 140 by the hollow drive shaft 141, and the other end of the conveying screw 120 fixed to the piston 110 is passed through the conveying nut 130. The hollow drive shaft 141 is to be stored inside.
이러한 중공구동축(141)은 이송너트(130)에 구동모터(140)의 회전력을 전달하는 기능 뿐 아니라, 이송스크류(120)가 외부로 노출되지 않도록 하여, 이물질로 인한 오작동 및 고장을 방지하는 역할을 수행하는 것으로, 구동모터(140)의 설치위치에 따라 이송너트(130)와 구동모터(140)의 연결수단으로서 기어나, 웜과 웜휠등 다양한 형태를 적용할 수 있으며, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 당업자라면 쉽게 변형할 수 있는 단순한 설계변경의 사항이므로, 본 발명의 청구범위에서 이를 구체적으로 한정하지 않는다.The hollow drive shaft 141 not only functions to transfer the rotational force of the driving motor 140 to the transfer nut 130, but also prevents the transfer screw 120 from being exposed to the outside, thereby preventing malfunction and failure due to foreign substances. By carrying out, according to the installation position of the drive motor 140, as a connecting means of the transfer nut 130 and the drive motor 140, various forms such as gears, worms and worm wheels can be applied, which belongs to the present invention Since it is a matter of simple design change that can be easily modified by those skilled in the art, the claims of the present invention are not specifically limited thereto.
이송너트(130)의 회전시 이송스크류(120) 및 이에 연결된 피스톤(110)은 회전하지 않아야 하며, 이를 위하여 도 2에서와 같이, 압출실린더(100) 내부에 회전방지홈(105)를 형성하고, 이에 대응하는 회전방지돌기(115)를 피스톤(110)의 외주면에 형성하였다.When the feed nut 130 rotates, the feed screw 120 and the piston 110 connected thereto should not rotate. For this purpose, as shown in FIG. 2, the anti-rotation groove 105 is formed inside the extrusion cylinder 100. , Corresponding to the anti-rotation protrusion 115 was formed on the outer peripheral surface of the piston (110).
이러한 피스톤(110)의 회전방지수단 또한, 비원형단면(非圓形斷面)피스톤을 적용하는 등, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 당업자라면 쉽게 변형할 수 있는 단순한 설계변경의 사항이므로, 본 발명의 청구범위에서 이를 구체적으로 한정하지 않는다.The anti-rotation means of the piston 110 also applies a non-circular cross-section piston, such as a simple design change that can be easily modified by those skilled in the art having ordinary skill in the art.
