PURPOSE:To make it possible to simultaneously carry out ball cleaning and maintenance of recovering apparatuses by installing two recovering apparatuses in parallel to each other, connecting one of these apparatuses to an ordinary cleaning line and another to a commonized recovering apparatus maintenance line after recovering balls and alternately changing the connection. CONSTITUTION:Cleaning of balls is effected in an ordinary cleaning line consisting of a water chamber 1, an arrester 2, a ball circulating pump 4, a recovering apparatus (A) inlet changeover valve 103A, a recovering apparatus 8A, a recovering apparatus (A) outlet changeover valve 105A and the water chamber 1. Next, the inlet changeover valve 103A and the outlet changeover valve 105A are closed, and an inlet changeover valve 102A and an outlet changeover valve 104A are opened. The recovering apparatus 8A is separated from the ordinary cleaning line and is connected to a recovering apparatus maintenance line after recovering balls. Furthermore, another recovering apparatus 8B holds balls after the maintenance. A recovering apparatus (B) inlet changeover valve 102B and a recovering apparatus (B) outlet changeover valve 104B are closed, a recovering apparatus (B) inlet changeover valve 103B and a recovering apparatus (B) outlet changeover valve 105B are opened. Thus, the recovering apparatus 8B is connected to an ordinary maintenance line. |
