본 발명은 회전드럼에 권취되는 권취물에 압착압력을 가하도록 된 압착롤에 관한 것으로, 특히 다수개의 예비조립(Pre-Assembly)재의 특성에 알맞도록 압착압력을 조절할 수 있도록 된 압착롤을 통해 예비조립재의 권취 및 연결부 공정의 자동화를 이룰 수 있도록 된 압착압력이 차등적으로 작용하는 압착롤의 구조에 관한 것이다.The present invention relates to a pressing roll adapted to apply a pressing pressure to a winding wound on a rotating drum, and in particular, a preliminary pressing through a pressing roll to adjust the pressing pressure to suit the characteristics of a plurality of pre-assembled materials. The present invention relates to a structure of a pressing roll in which a pressing pressure that enables the winding of the assembly material and the automation of the connecting part process is differentially performed.
일반적으로, 타이어는 여러 가지의 반제품이 결합되어 하나의 완성품 타이어를 이루게 되는데, 이러한 반제품중에 인너라이너와 사이드월의 예비조립재를 회전드럼에 권취할 때, 재료의 압착 및 재료들 사이의 공기를 제거하기 위하여 스폰지롤을 사용하여 재료를 회전드럼에 압착권취하게 되는데, 이 과정을 좀 더 자세히 살펴보면, 도 5 내지 도 6 에서 보는 바와 같이, 별개의 재료인 인너라이너와 사이드월이 겹쳐져 하나의 권취물이 되는 예비조립재(1)가 회전드럼(2)상에 권취되되, 이 회전드럼(2)에 권취되는 예비조립재의 외부에 실린더(102)에 의해 상하운동되는 스폰지롤(101)이 설치되어, 이 스폰지롤(101)이 상기 실린더(102)에 의해 상하운동되면서 상기 예비조립재(1)의 외피에 밀착되어 연동회전하게 되면, 상기 회전드럼(2)상에 권취되는 예비조립재(1)는 스폰지롤(102)에 의해 일정한 압착압력하에 회전드럼(2)에 권취되게 된다.In general, a tire is a combination of several semi-finished products to form a finished tire. Among these semi-finished products, when the preliminary assembly of the inner liner and sidewall is wound on a rotating drum, the compression of the material and the air between the materials are performed. Sponge rolls are used to remove the material onto the rotating drum. Looking at this process in more detail, as shown in FIGS. 5 to 6, the inner liner and the sidewall, which are separate materials, overlap one of the coils. A pre-assembled material 1, which is water, is wound on a rotating drum 2, and a sponge roll 101 which is vertically moved by a cylinder 102 is installed on the outside of the pre-assembled material wound on the rotating drum 2. When the sponge roll 101 moves up and down by the cylinder 102 to be in close contact with the outer shell of the preliminary assembly 1 and interlocks with each other, the preliminary assembly is wound on the rotary drum 2. The ash 1 is wound on the rotating drum 2 under a constant pressing pressure by the sponge roll 102.
그러나, 회전드럼에 예비조립재를 권취할 때, 종래의 스폰지롤은 롤의 형상에 의해 스폰지롤 전체에서 동일한 압착압력이 예비조립재의 프로파일(Profile) 각각의 부위에 가해지게 된다.However, when winding the pre-assembly to the rotating drum, the conventional sponge roll is applied to each part of the profile of the pre-assembly of the pre-assembly by the shape of the roll, the same pressing pressure throughout the sponge roll.
하지만, 예비조립재인 인너라이너와 사이드월과의 게이지(Gauge)차이 및 사이드월 자체의 프로파일상에 게이지차이가 있기 때문에 게이지가 두꺼운 부분은 더 큰 압력이 가해지게 되어, 권취시 인너라이너부위와 사이드월부위의 늘어나는 양이 상이하게 되므로 예비조립재의 연결부의 인너라이너 및 사이드월 각각의 겹침량을 동일하게 제어할 수 없을 뿐만 아니라, 연결부의 공정자동화도 불가능한 문제점이 있었다.However, there is a gauge difference between the inner liner and the sidewall, which is a preliminary assembly, and the gauge difference in the profile of the sidewall itself causes a greater pressure to be applied to the thicker portion of the gauge. Since the amount of increase in the wall portion is different, not only the amount of overlap between the innerliner and the sidewall of the connection part of the prefabricated material can be equally controlled, but also the process automation of the connection part is impossible.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 권취시 예비조립재의 부위별로 각각 상이한 압착압력을 가할 수 있는 압착롤이 구비되어, 상기 예비조립재의 권취시 각각의 재료에 알맞은 압착압력을 가할 수 있도록 된 압착압력이 차등적으로 작용하는 압착롤의 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, provided with a pressing roll that can apply a different pressing pressure for each part of the pre-assembly during the winding, the pressing pressure suitable for each material during the winding of the pre-assembly It is an object of the present invention to provide a structure of a pressing roll in which the pressing pressure to apply the differential action.

본 발명은 각형상의 양단에 다수개의 연결구(3h)가 형성되고 그 내부에 공급홈(3i)이 형성되는 한편, 이 공급홈(3i)과 연통된 유입구(3c)가 형성되며 이 유입구(3c)하부에는 공기압에 의해 작동되는 피스톤(3d)이 설치된 고정축(3b), 이 고정축(3b)에 삽입되도록 중앙에 개구부가 형성되며 내부(3g)와 원형의 띠인 연동부(3f)사이에 다수개의 베어링(3e)이 설치된 다수개의 디스크(3a)로 이루어진 압착롤(3)이 구비되되, 이 압착롤(3)의 연결구(3h)는 호스를 통해 통상의 공기펌프(도시않됨)와 연결되며, 이 공기펌프의 공기흐름을 제어하기위해 피엘씨(PLC;Programmable Logic Controller)와 다수개의 솔레노이드밸브(도시않됨)가 연결된다.According to the present invention, a plurality of connectors 3h are formed at both ends of a square shape, and a supply groove 3i is formed therein, while an inlet 3c communicating with the supply groove 3i is formed, and the inlet 3c is formed. In the lower part, a fixed shaft 3b provided with a piston 3d operated by air pressure is formed, and an opening is formed in the center so as to be inserted into the fixed shaft 3b. There is provided a pressing roll (3) consisting of a plurality of disks (3a) with three bearings (3e), the connector (3h) of the pressing roll (3) is connected to a conventional air pump (not shown) through a hose In order to control the air flow of this air pump, a PLC (Programmable Logic Controller) and a plurality of solenoid valves (not shown) are connected.
이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.
본 발명은 상기 공기펌프로 부터 압축공기가 상기 솔레노이드밸브 및 호스를 통해 상기 압착롤(3)의 연결구(3h)로 유입되며, 이 유입된 공기는 고정축(3b)의 공급홈을 통해 유입구(3c)로 유입되고, 이 유입된 압축공기에 의해 상기 피스톤(3d)이 압력을 받아 하강되어 상기 디스크(3a)의 내부(3g)를 밀게 되며, 이 디스크(3a)는 고정축(3b)과의 여유공간인 유격(d)만큼 하강될 수 있게된다.In the present invention, the compressed air from the air pump is introduced into the connector (3h) of the pressing roll (3) through the solenoid valve and hose, the inlet air through the supply groove of the fixed shaft (3b) 3c), the piston 3d is pushed down by the introduced compressed air to push down the inside (3g) of the disk (3a), the disk (3a) and the fixed shaft (3b) It can be lowered by the clearance d, which is a free space of.
한편, 상기 압착롤(3)을 임의로 몇개의 구역으로 나누고 이 구역별로 동일압력의 압축공기를 공급하게 되면, 몇개의 디스크(3a)에 동일한 압축공기를 전달할 수 있게 되므로, 권취재료의 특성에 알맞도록 압착롤(3)의 압착압력을 구역별로 조절가능한데, 이때 각각의 디스크(3a)별로 차등적인 압착압력을 조절하기 위해 피엘씨에 데이터를 설정하고 이 데이터의 출력신호에 따라 솔레노이드밸브를 제어하여 차등적인 압력의 공기를 공급할 수 있게 된다.On the other hand, if the pressing roll 3 is arbitrarily divided into several zones and the compressed air of the same pressure is supplied for each zone, the same compressed air can be delivered to several discs 3a, which is suitable for the characteristics of the winding material. The compression pressure of the pressing roll 3 can be adjusted for each zone so that the data is set in PLC to control the differential pressing pressure for each disc 3a and the solenoid valve is controlled according to the output signal of the data. It is possible to supply differential pressure air.
따라서, 예비조립재(1)가 회전드럼(2)상에 권취되는 과정에서 상기 디스크(3a)의 연동부(3f)가 예비조립재(1)에 맞닿으면서 베어링(3e)에 의해 상기 연동부(3f)만 회전하게 되는 한편, 전술한 바와 같이 차등적인 압착압력으로 예비조립재(1)에 압착압력을 가하게 된다.Therefore, the interlocking portion 3f of the disk 3a is in contact with the preassembled material 1 while the preassembled material 1 is wound on the rotating drum 2. While only the portion 3f is rotated, the pressing pressure is applied to the preliminary assembly 1 with the differential pressing pressure as described above.
이에 따라, 예비조립재(1)인 인너라이너 및 사이드월은 각각의 특성에 알맞은 압착압력으로 회전드럼(2)상에 권취되어 연결부의 겹침량이 균일하게 된다.As a result, the inner liner and the sidewall of the preliminary assembly 1 are wound on the rotary drum 2 at a compression pressure suitable for each characteristic, so that the overlapping amount of the connecting portions is uniform.
이상 설명한 바와 같이 본 발명에 따르면, 회전롤의 디스크가 각각 차등적인 압착압력으로 예비조립재를 압착하게 되어, 이 예비조립재가 회전드럼에 권취될 때 재료 각각의 겹침량을 균일하게 할 수 있음은 물론, 이 예비조립재의 연결부 공정을 자동화할 수 있는 효과가 있다.As described above, according to the present invention, the disks of the rotating rolls are pressed to the pre-assembly by the differential pressing pressure, respectively, so that the amount of overlap of each material can be made uniform when the pre-assembly is wound on the rotating drum. Of course, there is an effect that can automate the process of connecting the pre-assembly.
