In order to operate the electric motor 25, a storage battery 26 that supplies electric power is provided on the carrier 20 and a controller 27 that controls and supplies the electric power from the battery 26 to the electric motor 25 when required is provided on the carrier 20. It is provided. A roller may be used instead of the endless belt 24 of the transport unit 10.

In order to charge the storage battery 26 that supplies electric power to the electric motor 25 mounted on each of the transport units 10 at midnight, a power feeding station 14 having chargers 15 is provided at a plurality of locations along the guide rail 12. These power supply stations 14 are provided not in the entire loop of the guide rail 12 but in a part thereof as shown in FIG. 1, and an appropriate number is provided depending on the number and capacity of the storage batteries 26. Further, with respect to these power supply stations 14, all the carrier units 10 are divided into a plurality of groups, and the storage battery 26 of the carrier unit 10 is electrically connected to each group as appropriate.

A control device 27 is provided on the transportation platform 20 so that the endless belt 24 can be sorted when the transportation unit 10 arrives at the required sorting position, and the motor forward / reverse and reverse rotation signals are provided on both sides of the transportation platform 20. Reception sensors 45, 46 are provided. Therefore, when the transport unit 10 arrives at the desired sorting position, the transport unit 10 receives signals from the motor forward / reverse signal transmitters 47 and 48 at the sorting position, and the controller 27 determines a predetermined value. Electric power is supplied from the storage battery 26 to the electric motor 25 to rotate the electric motor 25 in the normal direction or the reverse direction to drive the endless belt 24 in a predetermined direction so that the load on the endless belt 24 is sorted to the predetermined sorting chute 16. Has become.

In addition, appropriate connecting members 51 are provided on the front and rear portions of the transfer frame 20 of each transfer unit 10 so as to endlessly connect with the adjacent transfer units 10. Furthermore,
Each transport unit 10 has a dog block 53 at the bottom of the transport platform 20.
Is provided and is driven via a dog block 53 by a drive device (not shown) driven by an appropriate electric motor.

In the high-speed automatic sorting apparatus of the present invention constructed as described above, the transport unit 10 connected by the usual appropriate driving device (not shown) is driven along the guide rail 12 formed in the required loop shape. The traveling wheels 31 of each transport unit 10 travel on the guide surface of the guide rail 12, and the guide rollers 32 along the side surface of the guide rail 12 limit the lateral movement. In the high-speed automatic sorting apparatus of the present invention which is driven and driven in this way, any cargo is supplied from the induction conveyor 18 for delivering the cargo to each of the transport units 10 regardless of the size of the regular shape, the irregular shape, and the size. It is loaded on top of 10 and transported to the sorting area.
The sorting of the transported goods is performed by an appropriate electronic control device such as a computer according to various codes displayed on the goods, and a signal transmitter 47 for the electric motor forward / reverse rotation at a predetermined sorting position,
The required command signal is sent to 48.

In this way, when each of the transport units 10 that carries the cargo transferred from the induction conveyor 18 and travels along the guide rails 12 and reaches a predetermined sorting position, an electronic control device (illustrated The motor forward / reverse signal transmitter 47 or 48 provided in the sorting chute 16 portion at a predetermined sorting position transmits a signal in response to a command signal from the
Receives this signal. Therefore, upon receipt of this signal by the electric motor forward / reverse signal receiving sensor 45 or 46 of the transport unit 10, electric power is supplied from the storage battery 26 to the electric motor 25 via the control device 27, and the electric motor 25 is operated in the forward or reverse direction. . Since the pulley 35 is rotated by the operation of the electric motor 25 via the pulley 36 and the timing belt 37, the pulley 35
The belt pulley 22 coaxial with is rotated to drive the endless belt 24 in a predetermined direction, so that the load loaded on the endless belt 24 is sorted into a predetermined sorting chute 16. After the package is sorted, a timer incorporated in the circuit of the control device 27 turns off the circuit of the control device 27 after a certain period of time, shuts off the power supply to the electric motor 25 and stops the endless belt 24. It

Each transport unit of the high-speed automatic sorting device of this invention
When charging the storage battery 26 of 10, the transport unit 10 is positioned so that each power feeding station 14 is positioned correspondingly for each group of transport units 10 divided into a plurality of groups, and the transport of each group is performed. One of the units 10 is electrically connected to the corresponding power supply station 14 and uses cheap midnight power from the power supply through the charger 15 to supply power to the power supply station 14.
The storage battery 26 can be charged by supplying power from the storage unit to the storage battery 26 of the transport unit 10. In this case,
If each storage battery 26 is electrically connected in parallel as in the illustrated embodiment, if one storage battery 26 of each group is connected to the power supply station 14, all storage batteries 26 of the group are charged, and if each storage battery 26 If they are not connected in parallel but are electrically independent, it is possible to connect several storage batteries 26 to each power supply station 14 and charge the storage batteries 26 sequentially if necessary. Therefore, whether the storage batteries 26 are connected in parallel or independent when electrically connected is appropriately determined according to the number and capacity of the storage batteries, and how many groups the transport unit 10 is divided into may be appropriately determined according to need.

As described above, according to the high-speed automatic sorting apparatus of the present invention, the endless belt is operated by operating the electric motor by the electric power from the storage battery mounted on the transport unit based on the sorting command from an appropriate electronic control device such as a computer. Can be operated in a predetermined direction to sort the load placed on the endless belt into predetermined sorting positions, and can transport and sort any type regardless of size, fixed shape, irregular shape, and size. In addition, since the electric power for performing the sorting operation is supplied from the storage battery of the transport unit to the electric motor through the control device, no special trolley duct power supply device or current collector is required, so that the equipment cost is not required. Maintenance costs can be greatly reduced, there is no problem of noise due to sliding of current collectors, and the power supply trolley duct is not required, and the facility space of the entire automatic sorting device can be reduced and saved. It is possible to achieve the effects such as. Further, the storage battery power required to perform the sorting operation is more suitable for the sorting device by using the midnight sorting time when the sorting device is not used in order to charge the storage battery at night by using the cheaper midnight power. It is possible to effectively utilize the above, and it suffices to provide a simple power supply facility, which is also useful for saving the facility cost.
