Document Type and Number:
Japanese Patent JPS5447214
Kind Code:
A
Abstract:

PURPOSE: To detect the abnormal state of division line even when a freight car stops halfway because of sudden disturbance, by detecting the line fullness in terms of the speed of conveyors and a signal of a section freight car detector.

CONSTITUTION: The conveyors 1, 2 are fixed to a wire rope 11 and driven by a motor 3. When the difference between the speed of an incoming freight car 7 and that of the conveyor 1 is small, the probability of contact of the conveyor 1 is with the freight car 7 is low. Even if the conveyor 1 comes into contact with the freight car 7, the variation in the speed of the conveyor 1 is small and the conveyor 1 1 conveys the car to the next section. When the freight car comes into contact with another freight car 9 stopped by an endless stop 12 and then stops, the car 8 does not move and the speed of the conveyor 2 falls down to the vicinity of zero even if the conveyor 2 comes into contact with the freight car 8. Then, when the conveyor 2 is disabled from operating by an instruction applied from a controller 10 on the basis of the signal of a section freight car detector 6 and speed of a speed detector 4, the other conveyor normally operates again and it can be detector 4, the freight cars are located in the section at the disabled conveyor
