Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport device including a transport vehicle guided by rails and driven by a secondary battery. One of the important issues related to transport vehicles equipped with secondary batteries is battery charging. That is, charging is required relatively frequently, the time required for charging is long, the work of monitoring whether charging is necessary and charging is cumbersome, and the operating rate tends to decrease.

Generally speaking, it is difficult to remove the battery from the aircraft and charge it, and then install the charged battery and drive the aircraft, but this does not avoid the hassle of replacing the battery. To deal with this, a charging evacuation route is set up separately from the normal transportation route so that the batteries can be charged while they are still mounted on the aircraft, and the transport equipment is designed to charge the batteries of the evacuated aircraft. is publicly known (Utility Model Application Publication No. 53-116986). However, such equipment cannot be used for transportation while it is being charged, which inevitably reduces its operating rate.

The present invention was developed in view of the above circumstances, and it is possible to charge the battery while it is installed, and also to charge the battery using a short idle time, and furthermore, it is possible to carry out cargo handling even during the charging period. The purpose of the present invention is to provide a conveyance device that can be used for such purposes.

The present invention will be described in detail below based on drawings showing embodiments thereof.

FIG. 1 is an external view of a conveying device according to the present invention, in which a rail 1 made of round pipes is supported by a ceiling, a beam, or other aerial structure via a number of substantially C-shaped support fittings 2. Rail IK
The suspended transport vehicle 3 has front and rear wheel parts 31.32 suspended on the rail 1, and is rotatably supported by the lower ends of these wheel parts 31.32 to connect the two, and has a suspended load capacity. A load rod (not shown) to support the load rod, a secondary battery 10 placed on the load rod (see Figure 4), and a cover 9 that covers the secondary battery 10 and the control circuit 6 (see Figure 4). The hoist 8 and the like are suspended so that the load is applied to the load rod, and the motor 33 provided on the front wheel section 31 and the motor 81 of the hoist 8, as well as their control circuits, are subjected to the load of the battery 10. There is.

The cargo (
It is necessary to stop the transport vehicle 3 at a position where cargo handling such as hoisting and lowering (not shown) is performed, but at such a stopping position, a permanent magnet 7 is attached to the lower surface of the rail l, and a cover 9 is attached. l on the upper surface of the
d An IJ-do switch 60 (not shown) is provided,
When the transport vehicle 3 moves, the reed switch is set to the permanent magnet 7.
The control circuit is configured so that the reed switch is activated when the motor 33 faces the motor 33, and the drive of the motor 33 is thereby stopped.
(See Figure 4). Note that such stopping positions, or stations, are not limited to transfer points where cargo is handled, but also include waiting points such as branching sections. A power feeder 4 as shown in FIG. 2.3 is attached to the station, and collectors 5, 5 are attached to the upper door of the cover 9 of the transport vehicle 3 in sliding contact therewith.

First, the feeder 4 is rounded at the end in the moving direction (front-back direction) of the carrier 3, and has a turret-like shape when viewed from the side as shown in FIG. ) also has an arc-shaped roundness. Approximately 1/2 of the transport vehicle 3
The substrate 41 is made of an insulating material such as a synthetic resin board, and has magnets 42 and 42 fixed to both longitudinal ends of the top surface, which allows the bottom surface of the rail 1 to be fixed at the position where the station is to be set. It is magnetically fixed. A groove 43.43 of an appropriate depth and appropriate width is formed in the center of the width direction at a position near the longitudinal end of the lower surface of the substrate 41, and a groove 43. A brass power supply type TILII 44.44 is fixed to the bottom. A hole reaching the electrode 44.44 is formed on the upper surface of the substrate 41, and a lead wire 45.degree. 45 is connected to the electrode 44.44 using this hole.

On the other hand, on the upper surface of the collector 5 and the cover 9, directly below the rail 1, power supply electrodes 44 and 44 are fixed at a distance approximately equal to the center-to-center distance between them. A metal plate fitting 5275 is in contact with the inner surface of the cover 9, and a brass clamp fitting 51 is in contact with the upper surface of the cover 9.
1. Hippo9. A bolt 53 is inserted through a hole formed in the fixture 52 and screwed into the cover 9 with a nut.

The clamp fitting 51 consists of a thick rectangular parallelepiped base metal fitting 51a and a flatter holding metal fitting 51b, and the contact 54 is clamped and fixed between the two. The contactor 54Fi is made of a plate spring material made of phosphor bronze, shaped into a flat ellipse (however, the longer diameter side end is bent downward), and the lower part is fixed under pressure. A contact member 55° 55 is fixed to the topmost portion of the outer surface of the contactor 54. As shown in FIG. 2 up and down
One end of a lead wire 56, 56 is inserted between the separated clamp fittings 51.

FIG. 4 shows the main part of the electric circuit of the device of the present invention. 61
is a commercial power source, which is stepped down to the required voltage by a transformer 62,
The step-down secondary voltage is applied to a rectifier 63, and the output of the rectifier 63 is applied to the feeders 4, 4 from lead wires 45, 45 via a floating charge control circuit 64.

On the other hand, the positive and negative fiji#'j of the battery 10 are connected to the motors 33 and 81 via the control circuit 6, while the lead wire 56
It is connected to the current collectors 5, 5 via 56.

The apparatus of the present invention constructed as described above operates as follows. That is, when the motor 33 is turned on by turning on a switch (not shown) and the transport vehicle 3 starts traveling, the drive of the motor 33 is stopped when the magnet 7 is detected by the reed switch, and the transport vehicle 3 stops at the station.

Then, the contactors 54 and 54 are connected to the power supply electrodes 44 and 44 respectively.
As a result, charging of the battery O from the power supply 61 or floating charge control circuit 64 side begins. In this case, the traveling distance of the transport vehicle from the reed switch activation to the stop will differ from the inertia K determined by the weight of the suspended load, but if the length of the power supply electrodes 44, 44 is selected appropriately. , the connection between the feeder 4 and the collectors 5, 5 is ensured. Further, since the lower surface of the feeder 4 is rounded by the substrate 41 and the electrode 44, the connection between the two can be ensured even if the body is slightly tilted. Moreover, it can be attached to and detached from the feeder armrest, making it easy to change the mounting position. Even while such charging is being performed, the control circuit 6 performs controls such as stopping the traveling motor 33 by applying electricity from the battery 10, and also performs controls to allow the motor 81 of the hoist 8 to be driven. I do. When a switch 82 provided on the hoist 8 is operated, the motor 81 is rotated to perform two hoisting operations and two hoisting operations. Furthermore, when the switch 64 is operated after cargo handling in this way, the motor 33 is rotated while being charged for a while, and the Yakate collector 5.5 is detached from the feeder 4 and transferred to the next station. I'm heading there.

5 and 6 show other structures of the feeder and current collector, and in the above-mentioned embodiment, the positive and negative charges of the feeder 4 are %44.
44 were arranged in the front-rear direction, but in this embodiment they are arranged side by side on the left and right, and the current collectors are also structured accordingly. That is, the clamp fittings 51', 51' are arranged side by side on the left and right with equal distance from the power supply electrodes 44', 44', and are installed so that the longitudinal direction of the contact 54' is in the moving direction of the carrier 3. ing.

Other parts similar to those shown in FIG. 2.3 are given the same reference numerals with a ``' and their explanation will be omitted.

In the device of the present invention as described above, floating charging is performed at the station, so a short time can be used for charging, there is no wasted time, and the operating rate can be improved. Furthermore, since power can be supplied to the load even during charging, there is no problem with control, cargo handling, etc., and it is highly convenient. During this charging, the combined load of the battery capacity and the charging circuit capacity can be removed, so cargo handling operations can be carried out safely even when the battery is in progress of discharging.

In particular, when using a charging device that allows rapid charging, charging to full capacity can be achieved using a chunk of time such as a lunch break, and the operating rate can be significantly improved.

In addition, when using the feeder 4 as shown in Fig. 2.3, the positive and negative electrodes 44, 44 are arranged at the front and rear in the moving direction, so the dimensional restrictions in the width direction are relaxed, and as in the embodiment, one The structure in which the electrodes are guided by the rails has the advantage that a sufficient electrode width can be ensured, and reliable charging can be performed even when there is horizontal shaking.

The wood-based lfl can also be applied to ground vehicles.
