With the configuration of the interlock circuit 51,
By establishing the voltage of the auxiliary power supply device 45 of the traveling vehicle 1 one front ahead, the relay MC1 is excited, the b contact 54 is turned off, and the power supply drive circuit 43 is inserted and connected in series to the AC wiring line 52. Powered and traveling vehicle 1 forward

In the child carriage 1B one unit behind, the relay M
When C1 is excited, its b contact is turned off,

Then, the same operation is repeated in the next child vehicle 1B, which is one vehicle behind. Therefore, the power supply drive circuit 43 is inserted into the AC wiring line 52 with a delay from the time when the auxiliary power supply device 45 rises in order from the parent carriage 1A. Therefore, the load when the power supply device 20 is turned on is limited to the number of the parent carts 1A located at the position where the guide line 16 is laid, so that the inrush current (surge) can be reduced. Further, in the child car 1B, the resistance 55 is first turned on to reduce the rush current to the power supply drive circuit 43.

As described above, since the inrush current when the power supply to the induction line 16 is turned on can be reduced, the power supply device

Can be made small, and a plurality of power supply pickup coils 37 can always be long enough to fit in the guide line 16. The length of the line 16 can be determined, so that the standard length of the guide line 16 can be adopted, the facility cost can be reduced, and the power cost can be reduced. further,
Since electromotive force is constantly generated in a plurality of pickup coils 37, even if a failure such as disconnection occurs in one pickup coil 37, the other pickup coil 37 can store electricity in the capacitor 48, and The operation can be continued and the reliability of the equipment can be improved. In addition, since electric power is supplied to the traveling carriage 1 without contact, current collection as in the past is unnecessary, noise can be eliminated, and maintenance costs can be reduced. In addition, whether the traveling vehicle 1 is traveling or stopped,
It goes without saying that power can be supplied.

The individual number and the cargo signal are input from the traveling carriage 1 that has moved to the position via the optical transceiver 41, and when the load 2 is not loaded, the conveyor is conveyed to the traveling carriage 1 via the optical transceivers 41 and 46. The forward rotation command signal of the device 3 is output, the load 2 is carried out to the traveling carriage 1 from the loading port 4A, and the sorting chute 4B that sorts the load 2 from the content of the load 2 is specified and its number is assigned to the traveling carriage 1. Store with number. When the forward rotation command signal is input through the optical transmitter / receiver 46 in the traveling carriage 1, the conveyor device 3 is driven to rotate in the forward direction to load the load 2 onto the belt 3A, and the load detector 39 detects the load 2. Upon detection, the driving of the conveyor device 3 is stopped.

Further, the sorting control device 40 of the equipment inputs the individual number and the presence signal from the traveling carriage 1 which has moved to the position of the sorting chute 4B, and when the load 2 is loaded, the sorting chute from the individual number. 4B number is searched, and when the traveling vehicle 1 is at the sorting chute 4B position, the forward rotation instruction signal or the reverse rotation instruction signal of the conveyor device 3 is output to the traveling vehicle 1 according to the left and right positions of the sorting chute 4B. Then, the number of the sorting chute 4B stored together with the number of the traveling carriage 1 is erased. In the traveling carriage 1, when the forward rotation command signal is input, the conveyor device 3 is driven in the forward rotation to carry the load 2 to the sorting chute 4B, and when the reverse rotation command signal is input, the conveyor device 3 is driven in the reverse rotation. 2 is carried out to the sorting chute 4B, and the presence detector 39 detects that the load 2 is exhausted, so that the driving of the conveyor device 3 is stopped.

By the above operation, all traveling carriages 1 connected to each other are driven by the linear motor 13 to travel on the traveling rail 9 at a constant speed, while each traveling carriage 1 receives a command signal from the sorting control device 40. Conveyor device 3 according to
Is driven to load the load 2 onto the belt 3A from the loading port 4A, and the load 2 is discharged to the designated sorting chute 4B to sort the load 2.

In this embodiment, a circuit for turning on the power supply drive circuit 43 to the AC wiring line 52 after the delay of the time when the auxiliary power supply device 45 rises is provided in order from the parent trolley 1A. This power supply 20 as shown in 10
If there is a margin on the side, it is possible to delete this circuit and leave only the circuit for reducing the rush current to the power supply drive circuit 43. At this time, N traveling carriages 1
Can be launched at once. Further, the resistor 55 is bypassed in order from the child carriage 1B which is closer to the parent carriage 1A.

According to the structure of the first invention, the power supply circuit fed from the power feeding line feeds power to the storage capacitor and the driving means to drive the driving means, and
Since the capacitor is charged and the capacitors are connected in parallel, it is possible to supply power to the driving means even for a traveling vehicle that is traveling on a fixed traveling route in which a power feeding line is not laid. In addition, since the capacitors are shared and charged by all traveling carriages, the capacity of the power supply equipment can be reduced, and it is sufficient to lay the power supply line only on a part of the fixed route, which reduces equipment costs. It is possible to significantly reduce the power cost.

Further, according to the structure of the second invention, an electromotive force is generated by the magnetic flux of the induction line in the power feeding coil provided in the traveling vehicle traveling on the fixed traveling route on which the dielectric line is laid, and the electricity is stored for storage.

It is possible to supply power to the driving means of a traveling carriage that is traveling. In addition, since the capacitors are shared and charged by all traveling carriages, the capacity of the power supply equipment can be reduced, and it is sufficient to lay a guide line only on a part of the fixed route, which reduces equipment costs. It is possible to significantly reduce the power cost. In addition, since power is supplied to the traveling carriage without contact,
The conventional power supply rail and current collector are not required, and the problems of noise and maintenance due to wear can be solved.

Further, according to the structure of the third aspect of the present invention, since the length of a plurality of power feeding coils may always enter the guide line, the length of the guide line may be shorter than the length of the constant traveling route. The length can be determined, so that the standard length of the guide line can be adopted, and the facility cost can be reduced. In addition, since electromotive force is constantly generated in multiple power feeding coils, even if one power feeding coil has a problem such as disconnection, other power feeding coils can store electricity in the capacitor, and The operation can be continued, and thus the reliability of the power supply equipment can be improved.

Further, according to the configuration of the fourth aspect of the invention, by delaying the order in which the power feeding coil is connected to the power supply circuit of each traveling vehicle, it is possible to reduce the inrush current when the power is turned on to the induction line, Therefore, the rated capacity of each device of the power feeding facility can be reduced, and the cost can be reduced.
