Abstract

도료의 색 교환 또는 세정시 컬러체인지밸브와 도장 건 사이의 남아 있는 여분의 도료를 피도물(被塗物)로 스프레이시켜 폐도료의 회수로 인한 오염의 원인을 제거하고 세정시간 등을 절약할 수 있도록 하는 도장로봇의 폐도료절감을 위한 방법과 그 장치를 제공하는 것이다.In order to reduce the cause of contamination and save cleaning time by spraying the excess paint remaining between the color change valve and the coating gun with the coating material during color change or cleaning of the paint It is to provide a method and apparatus for reducing waste paint of the painting robot.

종래에는 도장로봇에서 도료의 색 교환이나 도료세정시 도료라인에 남아 있는 도료를 버려야 함으로서 폐도료로 인한 오염의 원인이 되어 문제가 된다. 이를 방지하기 위해 종래에는 폐도료의 회수장치를 통해 폐도료를 회수하였다.In the related art, the paint robot must discard the paint remaining in the paint line when the color is changed or the paint is washed, thereby causing contamination by waste paint. In order to prevent this, in the prior art, waste paint was recovered through a waste paint collection device.

본 발명은 컬러체인지밸브에 시스템 컨트롤러와 연결되어 에어 및 도료 토출을 절환하기 위한 복수의 솔레노이드 밸브를 설치하고, 컬러 체인지밸브와 도장 건까지의 도료의 양을 측정하고 측정된 도료의 양에 대한 분사시간(폐도료분사시간)을 계산하여 그 계산된 값과 피도물의 스프레이 시간을 PLC(programmable logic controller) 프로그램상에 입력하여 상기 폐도료분사시간을 뺀 시간에 상기 솔레노이드밸브의 동작에 의해 컬러체인지밸브의 도료라인을 차단시키고, 상기 솔레노이드밸브를 통해 도장 건에 에어를 공급하여 상기 컬러체인지밸브와 도장 건까지의 도료라인에 남아 있는 여분의 도료를 피도물에 스프레이가 이루어지도록 한 것이다.The present invention installs a plurality of solenoid valves connected to the system controller in the color change valve to switch air and paint discharge, measures the amount of paint to the color change valve and the paint gun, and sprays the measured amount of paint. Calculate the time (waste paint injection time), input the calculated value and the spray time of the coating onto the programmable logic controller (PLC) program, and operate the solenoid valve at the time of subtracting the waste paint injection time. The paint line is blocked and air is supplied to the paint gun through the solenoid valve so that the excess paint remaining in the paint line to the color change valve and the paint gun is sprayed onto the coating material.
