PURPOSE:To automate cleaning work, when bodies to be cleaned which are circulated in a liquid pipe are cleaned, by counting the number of supplied bodies to be cleaned which are fed to a circulating system, the number of recovered bodies, and the number of normal bodies which are returned to the system, and computing and determing the number of the boides to be supplied based on the counted results. CONSTITUTION:The number of balls, which are washed in the circulating system and returned to a recovery device 13, is counted by a counter 12a. The number of the balls, which are supplied from a recovery device 14 to a circulating water path 2 and the number of the normal balls which are selected by a ball selector 15 and returned to a ball circulating system 11, are counted by a counter 12b. The number of the balls, which are inputted into the recovery devices 14 from a ball inputting device 17, is counted by a counter 12c. The results are inputted into a computation controlling device 100. The controlling device 100 computes the number of balls equired for the cleaning work according to a specified program together with other data, and controls a ball circulating pump 7, the recovery devices 13, 14, and 16, the inputting device 17, the selector 15, a vacuum pump and a pump 18 and 19, and valves 50-63. Thus, the cleaning work can be automated. |
