Description
본 발명은 온도나 습도를 일정하게 유지해야 하는 작업실 내부로 물품을 이송하거나 반출시키기 위해 형성한 물품 출입구의 개폐장치에 관한 것이다.The present invention relates to an opening and closing device of the article entrance formed to transport or take out the article into the interior of the work room to maintain a constant temperature or humidity.
공업적으로 생산되는 대부분의 물품은 일련의 연속된 공정에 의해 제조가 이루어지고, 일부 공정은 온도와 습도를 일정하게 유지한 상태에서 이루어지게 된다.Most industrially produced articles are manufactured by a series of continuous processes, and some processes are carried out with constant temperature and humidity.
예를 들어, 대형표지판을 제작하는 공장의 경우에는 표지판의 골조를 이루는 프레임 제작공정과 코팅이나 도색공정으로 크게 분류될 수 있고, 프레임제작공정은 용접이나 밴딩 또는 절곡공정등 기계적 가공공정이 포함됨으로 지붕을 구비한 개방된 구조의 공장에서 효율적인 작업수행이 가능하고, 코팅이나 도색공정등은 균일한 품질을 얻기 위하여 온도나 습도가 일정하게 유지되는 폐쇄된 작업공간에서 이루어진다.For example, in the case of a factory that manufactures a large signboard, it can be broadly classified into a frame fabrication process and a coating or painting process that constitute a frame of a sign, and the frame fabrication process includes a mechanical processing process such as a welding, bending or bending process. Efficient work is possible in an open factory with a roof, and coating and painting processes are performed in a closed work space where the temperature and humidity are kept constant to obtain a uniform quality.
이러한 공장에서 연속적이고 효율적인 공정수행을 위해서는 기계적 가공공정을 수행하는 외부작업실과 코팅이나 도색작업을 수행하는 내부작업실을 단일 생산라인에서 벽체로 각각 분리하고 벽체상에 개폐구조로 이루어지는 물품출입구를 설치하는 구조로 설계가 이루어진다.In order to carry out continuous and efficient process in these factories, the external workroom which performs the mechanical processing process and the inner workroom which performs the coating or painting work are separated into the wall in a single production line, and the opening and closing of goods having an opening structure on the wall are installed. The design is done by structure.
본 발명에 의한 출입구의 개폐장치는 이와 같은 생산시설에 적용되는 것으로 내부작업실의 온도와 습도유지를 위해 물품출입구를 신속하고 효율적으로 개폐시킬 수 있도록 하는 장치에 관한 것이다.The opening and closing device of the door according to the present invention is applied to such a production facility and relates to a device for quickly and efficiently opening and closing the article entrance for maintaining the temperature and humidity of the interior work room.
통상의 경우 물품출입구의 개폐장치는 벽체에 출입구를 형성하고 상기 출입구를 개폐시키기 위한 개폐문이 설치되는 구조로 이루어진다.In the usual case, the opening and closing device of the article entrance has a structure in which an opening and closing door is formed on the wall to open and close the entrance and exit.
일반적인 구조의 개폐문은 상부에 레일을 형성하여 인력에 의해 여닫는 구조로 이루어지거나 에어 또는 유압에 의해 개폐되는 구조로 이루어진다.Opening and closing door of the general structure is formed by the rail to the upper and lower by the manpower or made of a structure that is opened or closed by air or hydraulic pressure.
개폐문은 자체중량이 크고, 물건의 반출을 원활하게 하기 위해 충분히 크게 만들어지기 때문에 인력에 의해 여닫는 구조는 효율적이지 않으며, 에어 또는 유압식의 경우에는 에어유닛 또는 유압유닛등의 부대설비를 수반하기 때문에 설비 비용이 많이 소요되는 단점이 있었다.Opening and closing doors are large in weight and made large enough to smoothly carry things out.The opening / closing structure is not efficient due to manpower.In the case of air or hydraulic type, the doors are accompanied by additional equipment such as air unit or hydraulic unit. There was a costly disadvantage.
또한, 여닫는 과정에서 뒤틀림이 발생하여 부분적인 마모가 발생하거나 과도한 부하가 걸리어 쉽게 고장나는 원인이 되고, 벽체와의 틈새에 의해 내부작업실의 온도나 습도를 일정하게 유지하기 곤란한 문제점이 있었다.In addition, there is a problem that it is difficult to maintain a constant temperature or humidity of the interior work room due to the gap with the wall caused by the occurrence of distortion during opening and closing, partial wear or excessive load is easily broken.
또한, 종래의 개폐문은 측면으로 여닫는 구조로 이루어져 출입구전체를 개방한 상태에서만 물품을 입출시킬 수 있어 비효율적이며, 온도와 습도의 유지관리에 많은 비용이 소요되는 문제점이 있었다.In addition, the conventional opening and closing door has a structure that opens and closes to the side, it is inefficient to be able to enter and exit the article only when the entire entrance is open, there is a problem that the cost of maintaining the temperature and humidity is expensive.
본 발명은 개폐문의 상하 양단에 고정한 와이어로프를 벽체 상부에 설치한 단일 윈치구조에 메달아 승하강함으로서 물품출입구가 개폐되도록 하여 뒤틀림 없이 균일하게 개폐동작이 이루어지도록 하고, 경제적인 비용으로 개폐장치를 구성하며, 개폐문이 상하로 승강되도록 함으로서 물품의 반송량에 따라 최소의 크기로 개폐시킬 수 있도록 하여 내부작업실의 온도와 습도를 효율적으로 관리할 수 있도록 할 목적으로 안출된 것이다.The present invention is to open and close the article entrance by opening and lowering the medal entrance to a single winch structure installed on the upper wall of the wire rope fixed to the upper and lower ends of the door to enable the opening and closing operation without distortion, and to open and close the device at an economic cost It is designed to open and close the door to move up and down to a minimum size in accordance with the amount of conveyance of the article to efficiently manage the temperature and humidity of the interior work room.
이를 위하여 본 발명은 물품출입구의 양측에 가이드를 형성하고, 상기 가이드 내측에 개폐문을 삽입설치하고, 감속모터와 2개의 권취홈을 갖는 로프휠로 이루어지는 윈치구조를 물품출입구의 양측 중앙 상부 벽체에 부착하고, 개폐문의 양단 연장선상의 벽체상에 각기 대칭되는 구조로 아이들롤러를 부착하여 각각의 권취홈에는 와이어로프를 체결하고, 각각의 와이어로프는 아이들롤러에 걸어 개폐문의 양단 상부에 고정시키는 구조로 하여 감속모터의 정회전시 와이어로프가 감기면서 개폐문이 상승하여 열리고, 감속모터의 역회전시 와이어로프가 풀리면서 개폐문이 하강하여 물품출입구를 닫는 동작을 수행하는 물품운송용 출입구의 개폐장치를 제시한다.To this end, the present invention forms guides on both sides of the article inlet, inserts the opening and closing door inside the guide, and attaches a winch structure consisting of a reduction wheel and a rope wheel having two winding grooves to the central upper wall on both sides of the article inlet. The wire rollers are fastened to the respective winding grooves, and the wire ropes are fastened to the upper ends of the doors.
