본 발명은 교반기 구동헤드용 승강실린더의 안전장치에 관한 것으로, 더욱 상세하게는 분말 또는 액상으로 된 여러 가지 원료를 진공상태에서 교반하는 대형 교반기에서 교반날개를 갖춘 구동헤드와 함께 뚜껑을 통체로부터 개폐시키는 승강실린더가 상승되어 정지했을 때 그 승강실린더와 일체로 동작하는 지지축을 로커에 의해 구속되게 하여 승강실린더의 동작에 대한 신뢰성과 안전성을 향상시킴에 따라 안전사고의 위험을 방지할 수 있게 한 교반기 구동헤드용 승강실린더의 안전장치에 관한 것이다.The present invention relates to a safety device for a lift cylinder for an agitator drive head, and more particularly, to open and close a lid from a cylinder together with a drive head having a stirring blade in a large agitator for stirring various materials in powder or liquid state in a vacuum state. Stirrer which prevents the risk of safety accident by improving the reliability and safety of the operation of the lifting cylinder by restraining the support shaft which is integrated with the lifting cylinder when the lifting cylinder is raised and stopped. A safety device for a lift cylinder for a drive head.

일반적으로, 제약회사나 화장품회사 등에서는 분말 또는 액상으로 된 원료를 대량으로 혼합하기 위해 대용량의 교반기를 사용하고 있다.In general, pharmaceutical companies and cosmetics companies use large-capacity agitators for mixing a large amount of powder or liquid raw materials.

종래의 교반기의 일 예로서, 분말 또는 액상의 원료가 담기는 버킷(bucket) 형태의 통체를 서로 마주보는 한 쌍의 지지프레임에 스윙동작과 탈착 가능하게 설치하되 상기 통체의 개구부에는 각 지지프레임에 수직으로 동작되게 설치된 승강실린더에 의해 교반날개를 갖춘 구동헤드와 함께 뚜껑이 개폐가능하게 설치한 기술이 개시되어 있다.As an example of a conventional stirrer, a bucket-shaped cylinder in which powder or liquid raw materials are contained is installed in a pair of support frames facing each other so as to be swingable and detachable, but the openings of the cylinders are provided in respective support frames. Disclosed is a technique in which a lid is opened and closed with a driving head having a stirring blade by a lifting cylinder installed vertically.

즉, 통체에 원료를 투입하거나 교반된 원료를 꺼낼 때 승강실린더를 상승 동작시켜 교반날개를 갖춘 구동헤드와 함께 뚜껑을 수직으로 들어올린 상태에서 통체를 기울이거나 통체를 교체하였고, 원료를 교반할 경우에는 승강실린더에 의해 구동헤드를 하강시켜 통체의 개구부를 뚜껑으로 밀폐시킴과 동시에 교반날개를 통체 내에 위치되게 한 상태에서 교반작업을 하였다.That is, when putting the raw material into the cylinder or taking out the stirred raw material, the lifting cylinder is moved upward to tilt the cylinder or replace the cylinder while the lid is vertically lifted together with the drive head equipped with the stirring blade. In the lowering of the driving head by the lifting cylinder, the opening of the cylinder was sealed with a lid, and at the same time, the stirring was carried out while the stirring blade was placed in the cylinder.

그러나 상기 종래의 교반기는 승강실린더를 상승 동작시켜 교반날개를 갖춘 구동헤드와 함께 뚜껑을 수직으로 들어올려 정지시켰을 때 승강실린더에 공급되는 유압 또는 공압의 힘에 의해 구동헤드의 하중을 지탱하게 되었으므로, 승강실린더에 공급되는 압력이 중단되거나 변동이 생길 경우 구동헤드에서 가해지는 하중을 지탱할 수 없게되면서 구동헤드가 추락되는 안전사고의 위험과 승강실린더가 파손되는 문제점이 있었다. However, the conventional stirrer supports the load of the driving head by the hydraulic or pneumatic force supplied to the lifting cylinder when the lid is vertically lifted and stopped together with the driving head having the stirring blade by raising the lifting cylinder. When the pressure supplied to the lift cylinder is interrupted or fluctuates, it cannot support the load applied to the drive head, and there is a problem of a safety accident that the drive head falls and the lift cylinder is damaged.
