Abstract

PURPOSE:To eliminate an exclusive charging station by providing a charger in a station. CONSTITUTION:When a conveying vehicle 7 arrives at the vicinity of a station 15, the charging electrodes 21, 22 of the station 15 are energized by the current collecting electrodes 13, 14 of the vehicle 7 via a driving unit 23. Thereafter, the power source of a charger 16 is turned ON, to start charging a storage battery 8 placed on the vehicle 7. The vehicle 7 which arrives at the vicinity of the station 15 drives a transfer unit 24 in parallel with the above operation to transfer an article 25 to be transferred from the vehicle 7 to the station 15 or from the station 15 to the vehicle 7. When the transfer is completed, the power source of the charger 16 is turned OFF to disconnect the electrodes 21, 22 from the electrodes 13, 14.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a transport device that moves between a plurality of station devices and transports objects.

2. Description of the Related Art Conventionally, this type of conveying device is known, for example, from JST Newsvo.
As shown in L, 3 cubic meters, 5 p. 44, a dedicated charging station was provided.

The above conventional example will be explained below with reference to FIG. In FIG. 4, reference numerals 1 and 2 are conveyance devices such as conveyance vehicles that convey the object 25 to be conveyed. 3゜4.5 is conveyor device 1
, 2 and the conveyed object 26.

Reference numeral 6 denotes a charging device for charging the driving storage batteries mounted on the transport devices 1 and 2.

The operation of the transport device configured as described above will be described below.

First, the transport device 1 equipped with a storage battery transports an object between the station devices 3 and 4.5. When the storage battery capacity of the transport device 1 decreases, the transport device 1 stops near the charging station 6, and the charging device starts charging the storage battery mounted on the transport device 1. At the same time, the fully charged transport device 2 leaves the charging station 6 and starts transporting the object between the station devices 3 and 4.5. When the capacity of the storage battery 2 decreases, the transport device 1 or 2 enters the charging station and the fully charged transport device 1 or 2 starts transporting.

Problems to be Solved by the Invention However, with the above configuration, it is necessary to provide a dedicated charging station, which is disadvantageous in terms of effective use of space and cost, and also requires a transportation device that cannot perform transportation for charging. This always exists, and the problem has been that effective use of the device cannot be realized.

Means for Solving the Problems In order to solve the above problems, the transport device of the present invention includes a plurality of station devices and a transport device that moves between the station devices and transports the object to be transported. and the transport device is equipped with a storage battery for driving, and the station device is equipped with a charging device, and when the transport device stops near the station device, the storage battery is charged by the charging device. It is characterized by being equipped with a charging electrode.

Effect With the above configuration, each station device can be provided with a charging function, eliminating the need to install a dedicated charging station, and also allowing the transport device to stop at each station device.
It is an object of the present invention to provide a conveying device that not only charges a storage battery of the conveying device in parallel when transferring an object to be conveyed, but also achieves effective use of the conveying device.

Embodiment Hereinafter, a conveyance system device according to an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a station device and a conveying device in an embodiment of the present invention.

7 is a transport vehicle, and 8 is a storage battery mounted on the transport vehicle 7.

Storage battery so1m child e r 1o1d,, lead 1a1-11
12 to current collecting electrodes 13.14.

On the other hand, 16 is a station device, which has a built-in charging device 16. Terminals 17, 18 of the charging device 16 are connected to the conductor 19
, 20 are connected to charging electrodes 21, 22.

Furthermore, the charging electrodes 21 , 22 are slidable by the drive 23 in such a way that they can be applied to the current collecting electrodes 13 , 14 of the transport vehicle 7 .

The operation of the transport device configured as described above will be explained below using FIG. M1 and FIG. The current collecting electrodes 13 and 14 of the transport vehicle 7 are energized by the device 23 . After that, the power of the charging device 16 is turned on, and the storage battery 8 mounted on the transport vehicle 7 is turned on.
Start charging. On the other hand, the transport vehicle 7 that has arrived near the station device 16 drives the transfer device 24 in parallel with the above operation, and transfers the transported object 25 from the transport vehicle 7 to the station device 16 or from the station device 16 to the transport vehicle. 7 will be transferred.

When the transfer is completed, if the carrier 7 is to be moved to another station device, turn off the power to the charging device 16 and connect the charging electrode 21.22 to the current collecting electrode 13, 13 of the carrier 7.
The contact is released using the drive device 23. After that,
The carrier vehicle 7 starts traveling toward the next station device to be moved.

On the other hand, if there is no need for the transport vehicle 7 to move to another station device when the transfer is completed, charging continues until the need arises.

As described above, according to the present embodiment, a storage battery for driving is mounted on the transport device, a charging device is provided in the station device, and when the transport device stops near the station device, the charging device is activated. By charging the storage battery, there is no need to install a dedicated charging station device, and it can be charged in parallel with the transfer operation of the transport device, which improves the effective use of space, costs, and the efficiency of the transport device. It is extremely advantageous in terms of usage.

A second embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a configuration diagram of a conveyance system device showing a second embodiment of the present invention. In the figure, 7 is a transport vehicle, 8 is a storage battery mounted on the transport vehicle 7, and 013.14 is a current collecting electrode connected to the storage battery 8. On the other hand, 16 is a station device, and 16 is a charging device. Charging electrodes 21 and 22 are connected to the charging device 16. Furthermore, charging electrode 2
1.degree. 22 is slidable on the drive device 23 so that the same electrode can be biased against the current collecting electrodes 13, 14 of the transport vehicle 7.

What is different from the configuration shown in FIG. 1 is that the charging device 16 is not built into all station devices, but only some of the station devices, and the other station devices have only one conductor.
Charging electrode 21.2 of each station device according to 9 and 20
2 and the charging device 16 are connected.

As described above, by incorporating the charging device 16 into some of the station devices, the number of charging devices can be reduced, which is extremely effective in terms of cost and usage efficiency of the charging device.

Note that the charging electrodes 21 and 22 and their driving device 23 are as follows:
Although it is provided on the station device, it may be installed on the floor or other place outside the station equipment, and it does not need to be provided on all station devices or at all stopping points.

Effects of the Invention As described above, the present invention provides a conveying device including a plurality of station devices and a conveying device that moves between the stations and conveys the object to be conveyed, wherein the conveying device is equipped with a storage battery for driving, and The station device is equipped with a charging device, and when the transport device stops near the station device/device, the storage battery is charged by the charging device, thereby eliminating the need to provide a dedicated charging station, and Since the transfer device can be charged in parallel even during the transfer operation at the station device, it is extremely effective in terms of effective use of space, cost, and effective use of the transfer device.
