Detailed Description of the Invention (Industrial Application Field) The present invention relates to a transportation device using a transportation train driven by an onboard battery (rechargeable secondary battery), and particularly a battery charging means for the transportation device. It is related to.

(Prior art and its problems) In a transport device using a train equipped with a battery,
The on-board battery must be charged in a timely manner. Therefore, as described in Japanese Patent Publication No. 55-11537, for example, a transport train equipped with a battery is provided with a charging collector for the battery, and during the movement route of the train, suitable places that come into contact with the collector are installed. It was envisaged to provide a battery charging work zone with a long charging feeder line.

In such equipment, after disconnecting the onboard battery of the train that has entered the battery charging work zone and stopped from loads such as the power supply circuit of the running drive motor, the charging collector is connected to the charging power supply line. Charging voltage must be applied to the on-board battery via.

Conventionally, there has been no concrete or practical development of means for separating the battery from the load before the on-board battery starts charging, and there are no plans to put this type of battery-equipped transport device into practical use using a train. It was becoming.

(Means for Solving the Problems) The present invention proposes a conveyance device capable of solving the conventional problems as described above, and its characteristics are as follows. A relay for separating the battery from the load and a collector for supplying power to the relay are provided, and in the battery charging work zone,
The present invention is characterized in that a control power supply line that slides into contact with the power supply collector for supplying power to the relay, and a charging control device that supplies power to the charging power supply line after power is supplied to the control power supply line are provided.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

12b is pivotally supported, and furthermore, a motor 13 with a brake, which is interlocked with the drive wheel 10, is directly connected. This motor 13 is driven by electric power supplied from the battery 6 via the control device 7.

The driven trolley 5 includes the guide rail 1
An idling wheel 14 that fits into the lower guide groove 1b, vertical shaft rollers 15a and 15b for steady rest that fit into the guide groove 1b before and after this idling wheel 14, and right above the idling wheel 14. A vertical shaft roller 15c for steady rest fitting into the upper guide groove 1a of the guide rail 1 is pivotally supported, and two sets of charging collectors 16 are also supported.
a, 16b and two sets of control collectors 17a, 17b
is attached. Both trolleys 4,
5 are connected to the central position in the width direction of the truck main body 3a at a position directly below the guide rail 1 so as to be relatively rotatable around vertical pins 18, respectively.

In FIG. 3, reference numeral 19 indicates branching and merging route switching means 21 and 2 for branching and merging route switching to the main movement route 20 of the transport train 3.
As shown in FIGS. 1, 2, and 4, the guide rail 1 in this zone 19 has the charging collectors 16a, Charging power supply lines 23a, 23b and the control collector 17 which are in sliding contact with each other
Control feeder lines 24a, 24 that a, 17b slide into contact with
b is stretched. As shown in FIG. 4, a charger 25 is connected to the charging power supply lines 23a, 23b, and a charging control device 26 is connected to the control power supply lines 24a, 24b.

On the other hand, on the train 3 side, as shown in FIG. 4, the charging collectors 16a and 16b are connected to the battery 6, and the control collector 17
Normally closed contact 2 of relay 27 connected to a, 17b
7a and 27b are interposed between the motor control device 7 and the battery 6.

The conveyance device configured as described above operates the motor 13 using electric power supplied from the battery 6 to rotate the drive wheels 10, thereby achieving the following functions:
The transport train 3 suspended from the guide rail 1 can be moved forward or backward along the guide rail 1 to transport the object 8 supported by the hanger 9. Train 3 in this case
Running control such as starting, changing gears, and stopping at a predetermined position is automatically performed based on control signals given to the motor control device 7 of the electric train 3 from the ground side using light beams, magnetic force, radio waves, etc.

The electric train 3 whose voltage of the battery 6 has decreased to a certain level or less due to discharge is caused to enter the battery charging work zone 19 from the main movement route 20 by the branching route switching means 21 and is stopped. Of course, the battery charging timing can be automatically detected by the voltage detector attached to the battery 6, and based on the detection result, the train 3 can be automatically controlled to stop entering the battery charging work zone 19. .

Train 3 in battery charging work zone 19
When the train 3 stops, the charging control device 26 on the ground side operates based on the occupancy signal transmitted from the train 3 or the occupancy signal transmitted from the train detector on the ground side, and the control power supply lines 24a, 24b are activated. A control voltage is applied to. Therefore, a control current flows to the relay 27 via the control collectors 17a, 17b on the stopped train 3 side, the relay 27 is energized, the normally closed contacts 27a, 27b are switched to the open state, and the motor is controlled. The device 7 and the battery 6 are separated. The charging control device 26 on the ground side is connected to the control power supply line 2
After applying the control voltage to 4a, 24b, a charging signal is given to the charger 25 after a certain period of time has elapsed. A charging current is supplied to the battery 6 on the train 3 side through the battery 6 to charge the battery 6.

When charging is completed, the supply of charging current from the charger 25 is cut off, and after a certain period of time, the power supply to the control power supply lines 24a, 24b is cut off to demagnetize the relay 27, thereby opening the normally closed contacts 27a, 27b. The circuit is then returned to a closed circuit, and the battery 6 is connected to the motor control device 7. As a result, the train 3 is automatically started from the battery charging work zone 19, or the train 3 is started automatically from the battery charging work zone 19, or based on a start command from the ground side.
The electric train 3 can be started and returned to the main movement route 20 via the merging route switching means 22.

In addition, battery charging work zone 1 shown in Figure 3
9 can be installed in parallel at multiple locations on the main travel route 20, but a plurality of battery charging work zones 19 are installed in parallel at one location on the main travel route 20,
It is also possible to configure the train 3 to branch into an arbitrary empty zone by selecting it. Further, as shown in FIG. 5, a plurality of battery charging work zones 19 can be set in series in one branch route 28. In this case, charging/control power supply lines 23a to 24b shown in FIG. 4 for each zone 19,
A charger 25 and a charging control device 26 are provided, and in particular, when the zone 19 adjacent to the front becomes vacant, the train 3 in the following zone 19 is stopped from charging the battery and is transferred to the vacant zone 19 in front. It is desirable to control the battery so that the battery is moved to the next position, and battery charging is continued again at this point.

In the embodiment described above, the hanger 9 for supporting the object 8 to be transported is connected to the electric train 3 equipped with a battery, but the electric train 3 may be configured to pull a towed trolley for supporting the object 8 to be transported. Further, the electric train 3 can also be composed of a towing truck equipped with drive wheels 10 and a drive motor 13, and a towed truck on which the battery 6 is mounted. Further, in the above embodiment, a suspended monorail type train 3 is used, but the support and guide type of the train is not limited to this. Of course, the support type of the transported object is not limited to the hanging type.

(Operations and Effects of the Invention) As described above, according to the transport device using a battery-equipped train of the present invention, a train whose installed battery has reached its charging time can be brought into a battery charging work zone and stopped within the zone. If so, the charging control device applies a control voltage to the control power supply line to excite the relay on the train, and after disconnecting the battery from the load, applies a charging voltage to the charging power supply line. By loading the battery, charging current can be supplied to the battery from the charging power supply line through the charging collector on the train side, and the battery can be charged while it is mounted on the train.

Moreover, according to the configuration of the present invention, the necessary operation prior to charging the on-board battery as described above, that is, the operation of disconnecting the battery from the load (power supply circuit of the driving motor, etc.), can be performed in the charging work zone. This can be done remotely and automatically by simply supplying power to the control power supply line, and has a simpler structure and more reliable operation than mechanical means that operate the battery load disconnection switch on the train side. The battery load can be reliably automatically disconnected regardless of the stopping position of the train as long as it is within the installation range of the control power supply line.
Moreover, it can be implemented relatively inexpensively.
