Description

비닐하우스 보온덮개 개폐기용 클러치장치{CLUTCH INSTALLATION FOR A VINYL PLASTIC HOTHOUSE}CLUTCH INSTALLATION FOR A VINYL PLASTIC HOTHOUSE}

본 고안은 비닐하우스의 내부 천정에 설치되어 보온덮개를 개폐하는 데 사용하는 개폐기의 클러치장치에 관한 것이다.The present invention relates to a clutch device of the switchgear is installed on the inner ceiling of the plastic house and used to open and close the thermal cover.

일반적으로 사용되는 비닐하우스의 보온덮개 개폐장치는 주로 비닐하우스의 내부 천정 일측에 보온덮개 일단은 고정하여, 타단에서 모터가 장착된 이송형 권취봉이 보온덮개와 로프를 감으면서 개방하고, 타측에는 다시 이송형 권취봉의 로프를 감을 수 있는 모터가 장착된 고정형 권취봉을 설치하여 이송형 권취봉에 감겨진 로프를 다시 감으면서 보온덮개를 풀어내어 덮을 수 있게 한 것이 대부분이었다.In general, the insulation cover opening and closing device of a vinyl house is mainly fixed to one end of the insulation cover on the inner ceiling of the vinyl house, and at the other end, the transfer type winding rod equipped with the motor is opened while winding the insulation cover and rope, and the other side again. In most cases, a fixed winding rod equipped with a motor capable of winding a rope of a transfer winding rod was installed to reel the rope wound around the transfer winding rod so that the insulation cover could be uncovered.

따라서, 이송형 권취봉이 구동할 때에는 고정형 권취봉이 공회전되고, 반대로 고정형 권취봉이 구동될 때에는 이송형 권취봉이 공회전되게 하는 클러치장치가 필수적이었다.Therefore, when the transfer winding rod is driven, the fixed winding rod is idle, and conversely, when the fixed winding rod is driven, a clutch device for idling the transfer winding rod was essential.

그러나, 종래에 사용되고 있는 비닐하우스 개폐용 클러치장치는 주로 일측방향으로만 맞물려지는 한 쌍의 톱니기어를 마주보게 위치시킨 맞물림 클러치(일명: 포올 클러치)가 대부분이며, 이는 정회전시 가동 톱니기어가 나사부를 통해 전진하면서 고정 톱니기어와 맞물려져 구동케 하고, 역회전시에는 가동 톱니기어가 다시 나사부를 통해 후진하면서 고정 톱니기어와 벌어져 이간되게 한 방식이다.However, in the conventional vinyl house opening and closing clutch device, most of the engagement clutch (also known as a pole clutch) in which a pair of gear gears, which are mainly engaged in one direction, face each other is used. In this way, the gears are driven by being engaged with the fixed gears while advancing through them, and during the reverse rotation, the movable gears are retracted from the fixed gears while being separated from the fixed gears.

하지만, 이러한 전동방식은 가동 톱니기어의 잦은 전/후진으로 인해 나사부의 마모가 심하고, 구동시에는 가동 톱니기어를 나사부가 항상 밀고 있는 상태에서 동력을 전달하기 때문에 나사부에 하중을 집중시켜 파손이 쉽고 헛도는 일이 생겨 충분한 힘을 전달할 수 없게 될 뿐 아니라, 부품수명이 짧아져서 내구성이 부족하게 되는 문제점이 있었다.However, this transmission method is abrasion of the screw part due to frequent forward / reverse of the movable gear, and during operation, it is easy to be damaged by concentrating the load on the screw part because it transfers power while the movable gear is always pushed. There is a problem that not only can not be delivered enough power, but also the durability of the parts shortened life.

본 고안은 상기와 같은 종래의 문제점을 해소하고자 안출된 것으로써, 특히, 톱니기어와 같은 전동부재에 가압력을 부여한 상태에서만 맞물려져 피전동부재를 구동케 하는 종래의 전동방식을 탈피하여, 모터 구동시에는 키결합과 같이 구동축과 피동축을 핀으로 일체화되어 구동축에서 피동축으로 동력을 전달하되, 피동축이 독단적으로 구동될 때에는 구동축과 피동축을 일체화시킨 핀이 피동축에서 탈거되어 피동축만 자체적으로 공회전 될 수 있게 한 수단을 적용함으로써, 모터의 구동 및 정지에 따라 피동축의 전동 및 공회전이 용이한 클러치장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above-mentioned conventional problems, and in particular, it is only in a state in which a pressing force is applied to a transmission member such as a gear, thereby avoiding the conventional transmission system that drives the driven member. At the same time, the drive shaft and the driven shaft are integrated with the pins like a key combination to transfer power from the drive shaft to the driven shaft.When the driven shaft is driven arbitrarily, the pin integrating the drive shaft and the driven shaft is removed from the driven shaft. It is an object of the present invention to provide a clutch device that can be easily driven and idle by the driving shaft in accordance with driving and stopping of the motor by applying a means capable of idling itself.

이와 같이 된 본 고안의 클러치 방식은 이송형 권취봉이 구동할 때에는 고정형 권취봉이 공회전되고, 반대로 고정형 권취봉이 구동될 때에는 이송형 권취봉이 공회전되게 하는 비닐하우스 보온덮개 개폐기용 클러치로 가장 적합할 뿐 아니라, 구조가 간단하여 제작이 용이하며, 동력전달을 내구적이고 견고하게 전달시킬 수 있는 등의 이점이 있다.As described above, the clutch system of the present invention is most suitable as a clutch for a vinyl house insulation cover switchgear which allows the fixed winding rod to idle when the transportable winding rod is driven, and conversely, when the fixed winding rod is driven. The structure is simple and easy to manufacture, and there is an advantage such that the power transmission can be durable and firmly transmitted.

이하 본 고안을 첨부된 도면에 의거하여 보다 바람직하게 설명하면 다음과 같다.Hereinafter, the present invention will be described more preferably with reference to the accompanying drawings.

첨부도면 도1 내지 도4와 같이, 모터(A)와 연결된 감속기(A1)의 구동축(1) 내관에 피동축(2)을 공회전 될 수 있게 축설하되, 구동축(1)의 외주면에는 띠홈(11)과, 핀삽입공(12), 그리고 이 핀삽입공(12)의 내측 벽면에 홀(13)을 형성하여 핀삽입공(12) 측으로 탄지구(15)를 스프링(14)으로 탄설하고, 피동축(2)의 외관에는 정방향측에 걸림턱(21), 역방향측에 탈거면(22)를 형성한 핀안착홈(20)을 구성하여, 구동축(1)과 피동축(2)을 핀(3)으로 연결하며, As shown in FIGS. 1 to 4, the driven shaft 2 is installed in the inner tube of the drive shaft 1 of the reduction gear A1 connected to the motor A so that the driven shaft 2 can be idled, but the band groove 11 is formed on the outer circumferential surface of the drive shaft 1. ), The pin insertion hole 12, and the hole 13 is formed in the inner wall surface of the pin insertion hole 12, and the coalesced region 15 is springed to the pin insertion hole 12 side with the spring 14, In the outer surface of the driven shaft 2, a pin mounting groove 20 having a locking jaw 21 on the forward side and a stripping surface 22 on the reverse side is formed to pin the drive shaft 1 and the driven shaft 2. (3),

상기 구동축(1)의 외주면에는 일측으로 편심내관(40)을 가진 작동원판(4)을 구동축(1)에서 공회전 될 수 있게 착설하되, 이 편심내관(40)의 확장부(41)와 협소부(42)중간지점에서 편심내관의 중심을 향하도록 각각 볼트축봉(43)(44)을 장착하여 볼트축봉(43)(44)의 내측단이 구동축(1)의 띠홈(11) 내에서 상하측에 위치되게 하고, On the outer circumferential surface of the drive shaft (1) is installed so that the operating disk (4) having an eccentric inner tube (40) to one side can be idle in the drive shaft (1), the expansion portion 41 and the narrow portion of the eccentric inner tube (40) (42) The bolt shaft rods 43 and 44 are mounted so as to face the center of the eccentric inner tube at an intermediate point, so that the inner ends of the bolt shaft rods 43 and 44 are positioned up and down in the belt groove 11 of the drive shaft 1, respectively. Positioned at,

감속기(A1)와 작동원판(4) 사이에 감속기(A1) 측에서 작동원판(4)을 향해 압력을 가하여 작동원판(4)의 회전을 제어할 수 있게 가압수단이 구비된 디스크원판(5)을 개입시킨 개폐기용 클러치장치로 이루어 진다.Disc disc 5 provided with pressurizing means for controlling the rotation of the operation disc 4 by applying pressure from the reduction gear A1 toward the operation disc 4 between the reduction gear A1 and the operation disc 4. It is made of a clutch device for the switchgear through.

상기에서 가압수단은 감속기(A1) 측면에 다수개의 축봉(51)을 착설하고 각 축봉(51)에 스프링(52)을 장치하여 디스크원판(5)을 가압하므로 작동원판(4)의 회전을 제어하거나 In the pressure means is installed a plurality of shaft rods 51 on the side of the reducer (A1) and the spring 52 to each of the shaft rods 51 to press the disk disc 5, thereby controlling the rotation of the operation disk (4) do or

첨부도면 도6과 같이 디스크원판(5)과 작동원판(4) 사이에 전자자석 또는 영구자석 중에서 선택한 자석(53)을 착설하여 자기력으로 작동원판(4)의 회전이 ㅈ어되게 할 수 있다.As shown in FIG. 6, a magnet 53 selected from an electromagnet or a permanent magnet may be installed between the disc disc 5 and the actuating disc 4 so that the rotation of the actuating disc 4 may be controlled by magnetic force.

따라서 본 고안은 첨부도면 도5의 (가)와 같이, 모터(A)에 의해 구동축(1)이 →표 방향으로 정회전 될 때에 구동축(1)이 핀(3)을 편심내관(20)의 협소부(22) 측으로 회전시켜 핀(3)이 피동축(2)의 탈거면(22)을 따라 매몰되면서 핀안착홈(20)에 안착되어 핀(3)이 하측의 볼트축봉(44)에 걸리게 되고, 이때 핀(3)은 협소부에서 빠져나오지 못하게 되어 구동축(1)과 피동축(2) 그리고 작동원판(4)이 동시에 회전됨으로써 정회전 방향으로 동력이 전달케 되고 Therefore, the present invention, as shown in Fig. 5 (a) of the accompanying drawings, when the drive shaft 1 is rotated forward by the motor A in the table direction, the drive shaft 1 moves the pin 3 of the eccentric inner tube 20. As the pin 3 is buried along the stripping surface 22 of the driven shaft 2 by rotating toward the narrow portion 22, the pin 3 is seated in the pin seating groove 20, and the pin 3 is attached to the lower bolt shaft rod 44. At this time, the pin (3) does not escape from the narrow portion is driven by the drive shaft (1), driven shaft (2) and the operating disk (4) at the same time to transmit power in the forward direction

반대로, 첨부도면 도5의 (나)와 같이, 모터(A)에 의해 구동축(1)을 →방향으로 역회전하면, 구동축(1)이 핀(3)을 편심내관(20)의 확장부(21) 측으로 회전시켜 핀(3)이 핀안착홈(20)의 탈거면(22)을 따라 빠지면서 피동축(2)에서 완전히 분리되므로 On the contrary, as shown in (b) of FIG. 5, when the drive shaft 1 is reversely rotated in the → direction by the motor A, the drive shaft 1 causes the pin 3 to extend the eccentric inner tube 20 ( 21) so that the pin (3) is pulled out along the removal surface (22) of the pin seating groove (20) and completely separated from the driven shaft (2).

첨부도면 도5의 (다)와 같이 모터(A)의 구동축(1)은 역방향으로 정기가 제어되고 피동축(2)만 공회전하게 된다.As shown in FIG. 5 (c), the driving shaft 1 of the motor A is regularly controlled in the reverse direction, and only the driven shaft 2 idles.

이때 탄지구(15)는 탄성력을 가지고 핀(3)에 접촉하여 핀(3)의 위치를 유지시켜주며 디스크원판(5)은 핀(3)이 탈거되었을 때 작동원판(4)에 압력을 가해 작동원판(4)의 회전을 제어하는 것이다.At this time, the bullet strip 15 has an elastic force and keeps the position of the pin 3 in contact with the pin 3, and the disk disc 5 exerts pressure on the operating disc 4 when the pin 3 is removed. It is to control the rotation of the working disk (4).

따라서, 이송형 권취봉을 모터가 구동시켜 보온덮개와 로프를 감으면서 개방할 때에는 고정형 권취봉의 모터는 정지된 채 클러치장치에 의해 공회전하게 되고, 반대로 고정형 권취봉의 모터를 구동시켜 로프를 감으면서 보온덮개를 덮을 때에는 이송형 권취봉의 모터는 정지된 채 클러치장치에 의해 공회전하게 됨으로써, 보온덮개의 개폐가 원활하게 이루어지게 되는 구성이다.Therefore, when the transfer type winding rod is driven by a motor to open the insulation cover and the rope while being opened, the motor of the fixed winding rod is stopped and idling by the clutch device. On the contrary, the motor of the fixed winding rod is driven to keep warm while winding the rope. When the cover is covered, the motor of the transfer-type winding rod is idling by the clutch device while being stopped, so that the opening and closing of the insulating cover can be made smoothly.
