본 고안은 여러가지 용도로 구축되는 산업용 냉동, 냉장실의 여닫이식 대형문 개폐장치에 관한 것으로, 특히 래크기어를 형성한 공압실린더의 피스톤에 피니언을 치합시켜 피스톤의 좌,우 이동작동시 피니언이 회전되도록 하고, 상기 피니언의 회동에 따라 문이 개폐되도록한 단순구조의 여닫이식 대형문 자동개폐장치에 관한 것이다.The present invention relates to an opening / closing large door opening / closing device for an industrial refrigeration and refrigerating chamber, which is constructed for various purposes. In particular, the pinion is rotated when the piston moves left and right by engaging the pinion with a piston of a pneumatic cylinder having a rack gear. It relates to a sliding large door automatic opening and closing device of a simple structure to open and close the door according to the rotation of the pinion.

현재 각종 식품공장 또는 기계산업공장에서는 대형의 냉동, 냉장실을 구축하여 냉동이나 냉장이 필요한 각종 수산품등의 물품 보관용으로 사용하고 있으며, 이러한 냉동, 냉장실의 출입구는 물품의 운반작업을 용이하게 할 수 있도록 높고 넓은 폭으로 형성하고 있음에 따라 출입구의 개폐수단으로 설치되는 개폐문 역시 대형화 될수밖에 없었고, 이러한 대형 개폐문은 일정치 이상의 자체강도를 부여하기 위해 고중량의 금속판재나 시멘트재로 제작하고 있음에 따라 인력에 의한 개폐작동이 사실상 불가능했던 관계로 구동 모우터와 체인을 이용하는 체인전동식 개폐장치를 부설하여 문을 강제 개폐시키고 있는 실정이었다.Currently, various food factories or machinery industry factories have built large-scale freezers and refrigerators to store items such as fishery products that need to be frozen or refrigerated. As it is formed in high and wide width, the door to be installed as the opening and closing means of the entrance also has to be enlarged, and the large door is made of heavy metal plate or cement material to give its strength higher than a certain level. Since the opening and closing operation by manpower was virtually impossible, a chain-driven switchgear using a driving motor and a chain was installed to force the door to open and close.

이와같이 대형문 개폐수단으로서 설치되고 있는 종래의 체인 전동식 개폐장치는 고중량의 문 개폐작동이 반복시행되면서 전동수단인 체인이 쉽게 마모되거나 늘어나게 됨은 물론 실내에서 발산되는 습기에 의해 단기간내에 녹이슬게 되면서 잦은 유지보수가 요구되고 있었던등 그 사용수명이 매우 짧았고, 장치자체가 크고 조잡하여 그 설치작업에 어려움이 따르고 있었음은 물론 미관상으로도 좋지 않았으며, 또한 개폐작동시 심한 소음이 발생되는점 및 문 폐쇄상태에서의 실내기밀유지가 어려웠던등의 여러가지 문제점이 노출되고 있었다. 본 고안은 이와같은 종래의 제반 문제점을 감안하여 이를 효과적으로 해소하고자 안출된것으로, 힌지축을 중심으로 회동 개폐되도록된 그쪽의 문 상반에 적정길이 피스톤을 갖는 공압실린더를 각각 고정설치하고 상기 피스톤의 외면일측에는 래크기어를 형성함과 동시에 피니언을 래크기어에 치합시켜 회동가능하고, 상기 피니언 축은 문 상단일측에 연결고정해줌으로서, 공압유입방향에 따라 피스톤이 좌,우로 이동작동될때의 이송치가 피니언을 통해 전달되면서 2쪽의 문이 회동개폐되도록 하는 단순구조의 대형문 자동개폐장치를 제공하여, 그 제작이나 설치작업이 용이토록함은 물론 설치가동시 우수한 실내기밀 유지효과가 수반되도록하고, 문의 원활한 개폐작동으로 소음이나 고장이 거의 없도록하면서 그 사용수명의 반영구화 효과를 얻도록 하는 한편, 이미 설치사용되고 있는 기존 문에도 적용할 수 있도록하는데 주 목적이 있는 것으로 그 구성 및 효과를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.As such, the conventional chain electric opening and closing device installed as a large door opening and closing device is easily worn or stretched as a means of opening and closing a heavy door, and the chain is easily rusted or rusted in a short period of time by moisture emitted from the room. Its service life was very short, such as maintenance was required, and the installation itself was large and coarse, which made the installation work difficult, as well as unsightly. Various problems have been exposed, such as the difficulty of maintaining indoor confidentiality. The present invention has been devised to effectively solve this problem in view of the above-mentioned conventional problems, and fixedly install the pneumatic cylinders having the appropriate length pistons on the upper half of the door that is pivotally opened and closed about the hinge axis and the outer side of the piston The pinion is rotated by engaging the pinion with the rack gear at the same time as forming the rack gear, and the pinion shaft is fixed to one side of the upper end of the door, so that the feed value when the piston moves to the left and right according to the pneumatic inflow direction It provides a large door automatic opening and closing device with a simple structure that allows the two doors to be opened and closed while being transmitted through, so that the production or installation work can be easily performed, and the excellent interior confidentiality effect is accompanied when installing. Smooth opening and closing operation makes it possible to achieve the semi-permanent effect of the service life while making almost no noise or trouble. On the other hand, the main purpose is to be applied to the existing doors that are already installed and used, the configuration and effects will be described in detail based on the accompanying drawings as follows.

In forming the automatic opening and closing device, the piston 3 having a predetermined length is fixed to the upper side of the two doors 2a and 2b so that the pneumatic cylinder 4 is operated to move left and right along the pneumatic inflow direction. The outer surface of the piston (3) is formed by forming a rack gear (3a), each of the pneumatic cylinder (4) on the outer diameter of one side of the cutout portion (4a) to provide a pinion (5) having a predetermined pitch The rack gear 3a is fitted to the rack gear 3a, and the pinion 5 and the cutout 4a are covered with a closed box 13 while the shaft 5a of the pinion 5 is provided at each door. (2a, 2b) Connected to the fixed shaft 7 fixed to the bracket 6 on one side of the upper side as a coupling 8, the left side along the pneumatic inflow direction , The movement value of the piston (3) which is moved to the right is transmitted through the rack gear (3a) and pinion (5) and the fixed shaft (7) is configured to open and close the two doors (2a, 2b).

미설명부호로서 9는 출입구(1)에 설치되는 문틀을, 10은 문틀(9)에 고정설치되는 힌지구를, 11,12는 기밀 유지용 패킹을 각각 나타낸 것이다.Reference numeral 9 denotes a door frame installed at the doorway 1, 10 a hinged door fixed to the door frame 9, and 11 and 12 represent a packing for keeping airtight.

이와같은 구성으로 이루어지는 본고안은 개폐작동대상의 문(2a,2b)이 갖는 폭 및 개폐위치를 감안하면서 공압실린더(4)의 설치위치와 피스톤(3)의 좌,우행정 거리를 임의 설정하여 설치하게 되고, 상기 피스톤(3)의 왕복이동수단인 소정압의 공압은 통상의 콤프레셔(도시되지 않음)를 통해 얻도록함과 동시에 각각의 문(2a,2b)개폐작동을 위한 공압유입방향 조절은 공압실린더(4)의 양측부에 설치되는 솔레노이드밸브를 하나의 전기적 스위치(도시되지 않음)로서 선택적으로 조절작동토록 하거나, 각각의 공압실린더(4)에 별도의 스위치를 각각 설치하여 2쪽의 문(2a,2b)을 개별작동토록 하는 등의 통상적 방법을 이용토록 한다.The present proposal having such a configuration arbitrarily sets the installation position of the pneumatic cylinder 4 and the left and right stroke distances of the piston 3 while considering the width and the opening / closing position of the doors 2a and 2b. Pneumatic pressure of a predetermined pressure, which is a reciprocating means of the piston (3) is to be obtained through a conventional compressor (not shown) and at the same time to adjust the pneumatic inflow direction for opening and closing the respective doors (2a, 2b) The solenoid valves installed at both sides of the pneumatic cylinder (4) can be selectively adjusted as one electrical switch (not shown), or a separate switch can be installed in each pneumatic cylinder (4). Conventional methods, such as allowing doors 2a and 2b to be operated individually, should be used.

이러한 상태로서 설치되는 본 고안의 개폐장치는 조작자의 의도에 따라 스위치를 조작해주는 간단한 과정으로 2쪽의 문(2a,2b)을 자동 개폐시킬 수 있게되는바, 문틀(9)에 고정설치되는 힌지구(10)와 힌지축(2')을 통해 회동개폐가 가능한 상태로 출입구(1)에 설치되는 2쪽의 문(2a,2b)을 개방시키고자 스위치를 조작하게되면 콤프레셔를 통해 유입되는 적정압력의 공아에 의해 실린더(4)내의 피스톤(3)이 도면상 좌측방으로 이송되기 시작하면서 절개부(4a)를 통해 레크기어(3a)에 치합된 상태인 피니언(5)의 회동작동이 동시에 시작되게 되며 이때의 피니언(5) 회동치가 커플링(8)을 통해 문(2a,2b) 상단일측의 고정축(7)에 그대로 전달되면서 각각의 문(2a,2b)이 개방상태로 열리게 된다. 이때 피니언(5)의 축(5a)과 브라켓트(6)에 고착된 고정축(7)은 커플링(8)을 통해 어느정도의 유동이 허여되는 상태로 연결되어 있음에 따라 문(2a,2b)의 회동작동시 자체하중에 의해 비틀림하중이 발생된다하더라도 별다른 무리없이 원활하게 회동작동 되게되며, 이와같은 출입구(1) 개방상태에서 스위치를 조작하여 전술의 역방향으로 공압이 유입되도록하게 되면 각가의 문(2a,2b)은 원위치로 복귀되면서 출입구(1)를 폐쇄하고 있게되는 한편, 출입구(1)를 폐쇄하고 있는 상태의 문(2a,2b)은 콤프레셔에서 발생되는 소정압력의 공압에 의해 피스톤(3)이 항시 가압되고 있는 상태로서 일정위치에 머무르고 있게 됨에 따라 문틀(9)과 문(2a,2b)에 부착된 패킹(11,12)이 상호 긴밀하게 가압접촉되는 상태를 유지하고 있게 되면서 우수한 실내기밀유지효과를 얻게된다.The opening and closing device of the present invention, which is installed as such, is capable of automatically opening and closing the two doors 2a and 2b in a simple process of operating a switch according to the intention of the operator, which is fixed to the door frame 9 When the switch is operated to open the two doors (2a, 2b) installed at the entrance (1) in a state capable of rotating opening and closing through the earth (10) and the hinge shaft (2 '), the proper flow flowing through the compressor The piston 3 in the cylinder 4 is started to be transferred to the left side in the drawing by the ball of pressure, and the rotational operation of the pinion 5 engaged with the gear 3a through the cutout 4a is simultaneously performed. At this time, the pinion 5 is rotated as it is transmitted to the fixed shaft 7 on one side of the upper ends of the doors 2a and 2b through the coupling 8, and each door 2a and 2b is opened in an open state. . At this time, the shaft (5a) of the pinion (5) and the fixed shaft (7) fixed to the bracket (6) is connected to a state in which a certain flow is allowed through the coupling (8), the door (2a, 2b) Even if a torsional load is generated due to its own load during the rotational operation of the motor, it can be operated smoothly without any problems.If the pneumatic flows in the reverse direction of the above by operating the switch in such an opening (1) open state, each door (2a, 2b) is closing the doorway (1) while returning to the original position, while the door (2a, 2b) in the state of closing the doorway (1a) is a piston (pneumatic pressure of a predetermined pressure generated by the compressor) 3) is always in a pressurized state and stays in a predetermined position, so that the door frames 9 and the packings 11 and 12 attached to the doors 2a and 2b are kept in intimate pressure contact with each other. Indoor confidentiality effect is obtained.

한편, 본 고안의 개폐장치를 기설치된 여닫이식문에 추가적용하고자 함에 있어서는 피니언이 래크기어에 치합된 상태의 본 고안 공압실린더를 설치대상문의 상방에 고정설치해주고, 기존문의 상단일측에 고정축을 설치해줌과 동시에 상기 피니언축과 고정축을 커플링으로서 연결설치 해주는 간단한 과정으로 적용할 수 있게 되는 것이다.On the other hand, in order to apply the opening and closing device of the present invention to the already installed swing door, the present invention pneumatic cylinder with the pinion engaged with the rack gear is fixed to the upper side of the door to be installed, and a fixed shaft is installed on one side of the existing door. Simultaneously, the pinion shaft and the fixed shaft can be applied as a simple process of connecting and installing the coupling.

이상에서 살펴본 바와같은 본고안은 각종산업용 냉동 냉장실에 설치되는 여닫이식 대형문의 자동개폐장치로서 매우 유용하게 적용하도록 된것인바, 공압실린더와 피니언을 이용하는 단순원리의 개폐장치로서 문을 자동개폐토록하면서 실래밀폐효과 및 소음제거효과를 공히 얻도록하였고, 장치의 자체구조단순화로 그 제작 및 설치가 용이토록 하였음은 물론, 고장의 요소를 제거하여 사용수명 연장효과를 얻도록 하는 한편, 이미 설치되어있는 기존 문에도 쉽게 적용할 수 있도록 하면서 우수한 호환성을 겸비토록 하는등 여러가지 잇점을 갖는 유익한 고안인 것이다.As discussed above, this paper is intended to be very useful as an automatic opening / closing device for a large-sized door that is installed in various industrial refrigeration refrigerators. The simple principle of using a pneumatic cylinder and pinion is to open and close the door automatically. The sealing effect and noise reduction effect are both obtained, and the self-structure simplification of the device makes it easy to manufacture and install, as well as the effect of extending the service life by eliminating the factor of failure, It is an advantageous design that has various advantages, such as being easy to apply to doors and having excellent compatibility.
