As shown in FIG. 2, the trolley cleaning means 101 includes a trolley cleaning tank 119, a trolley cleaning nozzle 120, a trolley rinsing nozzle 121, a trolley cleaning pump 122, a trolley drain blower 123, a trolley drain nozzle 124, and a trolley. It has a transfer motor 125 and a transfer conveyor 126.

The trolley cleaning nozzle 120, the trolley rinsing nozzle 121, and the trolley cleaning pump 122 form a trolley cleaning section, and the trolley draining blower 123 and the trolley draining nozzle 124 form a trolley draining section.

The trolley C conveyed by the trolley tilting conveyor 112 of the trolley transport mechanism 102 on the rear side B is transferred from the trolley tilting conveyor 112 to the transport conveyor 126 in the trolley cleaning tank 119.

The transport conveyor 112 transports the carriage C in the carriage cleaning tank 119 along the transport direction X by driving the carriage transport motor 125. The trolley C is washed with the cleaning liquid from the trolley cleaning nozzle 120 while being conveyed, and then rinsed with the rinsing liquid from the trolley rinsing nozzle 121.

The trolley C that has been rinsed is blown from the trolley draining nozzle 124 with dry air at room temperature for draining from the trolley draining blower 123. As a result, the trolley C is drained. The trolley C after the draining process is pushed out from the transport conveyor 126 to the trolley take-out slope 116 of the trolley transport mechanism 103, so that the trolley C is discharged to the trolley discharge port 115 while being conveyed along the inclined trolley take-out slope 116. It has become so.
