PURPOSE:To automatically detect and correct misalignment of a vessel and a cleaning nozzle by constituting the washer so that the position of the cleaning nozzle or a carrier means is controlled when a sensor detects that the position of the vessel is misaligned at a point of time wherein the cleaning nozzle starts follow-up. CONSTITUTION:A command is sent to the sensors 36, 38 when a vessel 10 held to the holder of a carrier mechanism 2 is advanced to the direction shown in an arrow A and a cleaning nozzle 12 returned to the retreating position (left shown in a figure) starts flow-up for this vessel 10. For example, when a bridge and a holder are moved to the position of a broken line and the front side leg part of the bridge approaches the sensor 36 of the right side, this sensor 36 detects that the chain conveyor 4 of the carrier mechanism 2 is shrunk. A ball screw jack 32 is actuated to move a movable frame 14 to the right. The position of the cleaning nozzle 12 is allowed to coincide with the mouth of the vessel 10 held on a holder. |
