Abstract

PURPOSE:To automate the painting inspection of the internal surface of an empty can be injecting a conductive liquid into the empty can, immersing an electrode rod in the conductive liquid in the can and pressing a stylus electrode against the external surface of the can, and measuring the current value between both electrodes. CONSTITUTION:The empty can B which is conveyed continuously and already painted is extracted by an extracting mechanism 10. The empty can B is sucked by a suction pad 20 and moved to a weighing position P. Then a prescribed amount of conductive liquid (salt water) is injected into the empty can B. Then the can B is moved to a measurement position Q and the electrode rod is immersed in the conductive liquid in the can B. Further, the stylus electrode is pressed against the external surface of the can B and a DC voltage is applied between the electrode rod and stylus electrode. At this time, if the painting on the internal surface of the can B is defective and its metallic part is exposed, a current larger than a prescribed value flows between both electrodes, so the current value is measured to judge the painting as defective painting. Thus, the current value between the electrode rod and stylus electrode is measured, so the painting inspection of the can internal surface is automated and the reliability is improved.
