Document Type and Number:
Japanese Patent JP3635344
Kind Code:
B
Abstract:
PURPOSE: To make a self-propelled vehicle ascend/descend by a simple structure to prevent stopping the self-propelled vehicle further with a small shock.
CONSTITUTION: A self-propelled vehicle running rail 11 is constituted of a lower horizontal track 21, down facing circular arc track 22, tilt track 23, up facing circular arc track 24 and an upper horizontal track 25 successively connected in a lengthwise direction of the rail. In the upward of the self-propelled vehicle running rail 11, an endless chain 43 is arranged so that its lower side moving route is placed in parallel to the self-propelled vehicle running rail 11. A driven pawl 36 is provided in a self-propelled vehicle 12. In the chain 43, a drive pawl 45 is provided so that it can be engaged with the driven pawl 36. The chain 43 is driven at a speed equal to speed of the self-propelled vehicle 12 running on the lower/upper horizontal tracks 21, 25 by a motor 44. The motor 44 is controlled in a manner wherein its driving is started, when the self-propelled vehicle 12 approaches one of the lower/upper horizontal tracks 21, 25, and stopped when passing through the other.
