Abstract

PURPOSE:To manufacture a light vehicle causing no pollution by transmitting a light beam on an optical fiber in a light transmission casing to a light receiving element mounted on a carrier and then subjecting the light beam to photoelectric conversion thereby producing power for a carrier. CONSTITUTION:A plurality of light receiving elements 3 are mounted on the opposite sides of a truck 1 of a carrier traveling, while mounting a cargo 8, on a track or a trackless route (travels on a track 2 on the drawing). A plurality of optical fibers 5 contained in a light transmission casing 4 arranged along the track 2 transmit light to the light receiving elements 3. The optical fibers 5 transmit light, emitted from a light source (not shown), to the light receiving elements 3 while controlling through a controller. The light receiving elements 3 subject thus received light to photoelectric conversion thus producing power for the carrier. According to the invention, a light carrier causing no pollution can be manufactured.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying machine that runs on a track or on a non-track surface using the power of a linear motor, a conventional motor, etc., and particularly relates to its power source.

0002

BACKGROUND OF THE INVENTION Conventionally, storage batteries have been used in this type of transport machine as a power source for automatic steering control and for running.

0003

[Problems to be Solved by the Invention] This conventional storage battery has the disadvantage that it generates gas during discharge, which pollutes the clean environment.

[0004]Furthermore, the storage battery is heavy and accounts for most of the weight of the conveyor, making it difficult to reduce its weight.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transport machine that is lightweight and prevents environmental pollution.

[0006]

[Means for Solving the Problems] According to the present invention, in a carrier machine that runs on a track or on a non-track surface using the power of a linear motor, a normal motor, etc., the power source is a device that converts light energy into electrical energy. It is composed of a rechargeable power source and is provided with light transmitting means for the power source.

[0007] The non-rechargeable power source is preferably constructed from a light receiving element such as a solar cell.

[0008] Furthermore, it is preferable that the light transmitting means is configured to transmit light from a light emitting source such as a laser device through an optical fiber or the like in accordance with the movement of the conveyor.

[0009]

[Operation] In the transport machine configured as described above, the light-receiving element of the traveling transport machine converts the transmitted optical energy into electrical energy and supplies it to the autopilot control circuit and the power circuit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

[0011] In FIGS. 1 and 2, a transport trolley 1 is loaded with objects 8 and travels on a track 2 using, for example, a magnetic levitation system.

[0012] Inside the trolley 1, an automatic steering control circuit and a running coil excitation circuit (not shown) are provided, and these are used to receive light from a solar cell or the like that converts light energy into electrical energy, which is a non-rechargeable power source. It is connected to element 3. A plurality of light receiving elements 3 (in the illustrated example, two each) are provided on both sides of the truck 1. Note that a small auxiliary charger (not shown) may be further connected to the light receiving element.

On the other hand, on the ground on both sides of the track 2, light transmitting cases 4, 4 are erected along the track 2 at positions facing the light receiving element 3, respectively. A plurality of optical fibers 5 are provided inside the light transmitting case 4, and these optical fibers 5 are connected to a light emitting source 7 such as a laser device via a controller 6, and the light from the light emitting source 7 is As shown, the light is transmitted to the light receiving element 3.

In FIG. 3, the ends of the optical fibers 5, 5 on the side of the light emitting source 7 disposed in the light transmitting case 4 are aligned on a straight line L, and the controller 6 moves the light along this straight line. It is designed to be able to reciprocate in opposition to each end of the fibers 5, 5, . . . Therefore, the controller 6 can be moved to transmit light to the light receiving elements 3, 3 as shown by the arrow A in accordance with the movement of the carrier 1.

FIG. 4 shows another embodiment of the light transmitting means,
An optical fiber group 5A in which optical fibers 5, 5 are arranged in parallel perpendicular to the longitudinal direction of the light transmitting case 4 is connected to the light transmitting case 4.
A plurality of groups 5A, 5A, . . . are arranged perpendicular to the longitudinal direction of the This is an example in which the fiber 5C is connected to the light emitting source 7, and the controller 6 switches the repeater 5B to transmit light in the same manner as in FIG.

The light-receiving element 3 of the trolley 1 configured as described above receives the light energy transmitted from the light-emitting source, converts it into electric energy, and supplies the electric energy to the autopilot control circuit and the coil excitation circuit. The trolley 1 is made to float and travel.

[0017]

Effects of the Invention Since the present invention is configured as described above, it is possible to eliminate the conventional storage battery, prevent environmental pollution, reduce the weight of the conveyor, and control the position, speed, etc. It is also extremely effective when only sensors and control circuits are mounted. It also saves regular charging time.

Furthermore, if the present invention is applied to a conveyor that travels inside a vacuum tube, tunnel, etc., it can operate for a long period of time without destroying the vacuum because of contactless power reception.
