The speed detection unit 17 that captures the information of the sensor 14 to grasp the position of the traveling carriage, the information of the address sensor 13 and the speed sensor 14 are captured, the position of the traveling carriage K is grasped by the speed detection section 17, and this speed detection is performed. The signals from the unit 17 and the sorting schedule data setting unit 16 are transmitted to the ground station A through the sorting result processing unit 15.

  Therefore, on the ground side, the position of the traveling carriage K is grasped by the address sensor 13 and the speed sensor 14, and the sorting timing is the sort chute set in the sorting schedule data setting unit 16 to sort the articles. Along with the information on whether or not the sorting result processing unit 15 transmits the control information from the ground station of the non-contact power feeding device to the traveling cart side as control information on how many seconds after the control information transmission starts the tilting operation. The

  On the traveling carriage side, the electric power obtained from the onboard station of the non-contact power feeding device is stored in the capacitor 21, and the control information is sent to the control device 22. In the control device 22, the tray 2 is tilted and paid out when a set time has elapsed since reception. When the tray 2 is tilted, information such as the speed and position of the traveling carriage is used. It is possible to synchronize and deliver the conveyed article to a precisely specified sorting chute. This controls the tilt timing by registering the timing (time) information to be sorted for each article handled by the control device on the ground side, and performing the reverse calculation from this time and transmitting the tilt timing as a control signal. can do.

Further, as shown in FIG. 2, the delivery articles are dispensed to each sorting chute C1a, C1b,..., C1n or C2a, C2b,.
