Description

정량 토출 장치의 자동 세정 제어 방법{Cleansing Control Method for fixed quantity discharger}Automatic cleaning control method for metered discharge device {Cleansing Control Method for fixed quantity discharger}

본 발명은 정량 토출 장치의 세정 제어 방법에 관한 것으로, 더 상세하게는 종래의 정량 토출 장치 실린더를 세정하기 위해 장치를 분해하는 세정 방법대신에 실시간적으로 실린더 내부에 용제를 흡입시켜 정량 토출 장치를 자동 세정하는 방법에 관한 것이다.The present invention relates to a cleaning control method for a metered volume ejection apparatus, and more particularly, in order to clean the metered volume ejection apparatus cylinder, the solvent is sucked into the cylinder in real time instead of a cleaning method for disassembling the apparatus. It relates to a method of automatic cleaning.

일반적으로 자동차 생산시 의장작업라인에서 자동차 도장표면의 손상을 방지하기 위하여 표면에 일정량의 아크릴 수지류를 코팅재로 하여 실린더 내의 피스톤과 연결되어 서보모터로 정량 토출하여 도포를 하게 된다. 이때 실린더와 연결된 로봇고장이라든가 어떤 이유에서든 정량 토출 장치를 일정시간 이상 멈추어야 할 경우가 있다. 이때 정량토출장치의 실린더 내를 세정하지 않을 시에는 용액이 용제와 용질로 부분적으로 분리되거나, 용액이 공기와 접촉해 건조되면 실린더 내벽에 고착되어 굳어져 실린더 내의 실(seal)이나 피스톤의 패킹(packing)의 수명을 급속하게 저하시키거나 토출측 배관 경로에서 유체흐름을 방해하거나 균일도포를 방해하여 품질 불량의 원인이 된다.In general, in the production of automobiles, in order to prevent the damage of the painted surface of the car in the design work line, a certain amount of acrylic resin is used as a coating material, which is connected to the piston in the cylinder, and is quantitatively discharged to the servomotor to apply the coating. At this time, it may be necessary to stop the fixed quantity ejection device for a certain time for some reason, such as a robot failure connected to the cylinder. At this time, when the cylinder of the metered-discharge device is not cleaned, the solution is partially separated into a solvent and a solute, or when the solution comes into contact with air and is dried, it is fixed on the inner wall of the cylinder and solidified to seal the seal or piston in the cylinder ( It can cause the quality defect by rapidly deteriorating the life of the packing), obstructing the flow of fluid in the discharge-side pipe path, or impeding uniform coating.

The purpose is to provide a method.

본 발명은 정량토출 자동세정 제어 장치에 있어서 실린더에 용액을 공급하는 용액실과 병렬되게 제2밸브를 구비한 용제실을 설치하여 노즐,용액실,용제실과 연결된 밸브상태에 따라 실린더 내의 피스톤을 전진, 후진 시켜 실린더 내의 용액을 세정하므로써 달성된다.The present invention is to install a solvent chamber having a second valve in parallel with the solution chamber for supplying the solution to the cylinder in the metered discharge automatic cleaning control device to advance the piston in the cylinder according to the valve state connected to the nozzle, the solution chamber, the solvent chamber, This is accomplished by backing up to clean the solution in the cylinder.
