Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automated guided vehicle.

(Purpose of the Invention) This invention is an unmanned guided vehicle that can be easily manufactured at low cost and in a short time according to the size and shape of an article to be conveyed, the size of a factory where the article is used, and a traveling path. It is intended to provide.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

The automated guided vehicle 1 has a front vehicle body 2, a rear vehicle body 3, and a loading platform 4 fixed to them by means such as welding and bolt connection.

The rear vehicle body 3 is the same as the front vehicle body 2,
It is the one that changed the direction by 80 degrees. Therefore, only the configuration of the front vehicle body 2 will be described below. A pair of left and right driven wheels 8 are provided at the bottom rear portion of the vehicle body 7 of the front vehicle body 2 so as to freely rotate. Further, a wheel receiver 10 is provided at the center of the front portion of the vehicle body 7 in the left-right direction so as to be vertically swingable by a pivot 11. A shock absorber 12 including is interposed.
Steering / driving wheels 15 are provided on the wheel receiver 10 as described below. That is, a steering shaft 16 is rotatably provided horizontally on the wheel receiver 10, a bracket 17 is provided at the lower end of the steering shaft 16, and a horizontal rotary shaft 18 is rotatably fitted to the bracket 17.
Wheels 19 are fixed to the rotating shaft 18 so as to be stopped. The wheel 19 is rotated by rotating a rotary shaft 18 directly or via a speed reducer by a motor 20 provided in the bracket 17 and having a built-in brake or the like. A chain wheel 22 is attached to the steering shaft 16.
The endless chain 26 is stretched over the chain wheel 22 and the chain wheel 25 of the output shaft 24 of the steering motor 23 having a built-in brake or the like. The motor 23 is provided on the wheel receiver 10. The steering / drive wheels 15 of the front vehicle body 2 and the steering / drive wheels 15 of the rear vehicle body 3 are operated in synchronization with each other.

The loading platform 4 is provided with a pair of forks 28 that are article transfer devices that can move back and forth in the left-right direction and can move up and down. The length of the bed 4 and the article transfer device can be freely changed according to the size and shape of the article to be conveyed, the size of the factory where the article is used, the traveling path, and the like.

A large number of air ejection nozzles 29 are provided downward at required portions such as the front part of the automatic guided vehicle 1, and the automatic guided vehicle 1 is provided with these nozzles.
The discharge port of the blower 30 mounted in is connected. With such a configuration, it is possible to prevent dust and dirt from adhering to the steering / drive wheels 15 and the driven wheels 8 by running while cleaning the traveling floor surface by blowing away dust and dirt from the traveling floor surface. Can be done.

(Effect of the Invention) The present invention has the following effects due to the above-described configuration.

Since the front body and the rear body are the same, and the cargo bed is handed over to them, that is, by mass-producing the same vehicle body and connecting them to the cargo bed, Since it is possible to easily make an unmanned guided vehicle according to the size and shape of the conveyed goods, the size of the factory where it is used, the traveling path, etc. Can be manufactured.

The front vehicle body and the rear vehicle body have one steering / driving wheel at the center in the left-right direction, and a pair of left and right driven wheels that freely rotate, that is, the front and rear vehicle bodies are independent. Since it can stand on the floor and can run independently, it is easy to connect them to the cargo bed.
