Method for controlling movement of travelling carriers
First Claim
1. A method for controlling movement of travelling carriers in conveying equipment where self-propelled travelling carriers move on their own at a fixed low operating speed while maintaining continuous motion in a moving direction in a work area within a moving path for the travelling carriers, the method comprising:
- providing each of the travelling carriers with a data communication means for performing data communication between front and rear adjacent travelling carriers within the work area and providing each travelling carrier with an on-board communication device operable to perform data communication with a ground-based communication device;
the ground-based communication device being disposed at a first end of the work area, and the ground-based communication device sending a movement permission signal to the on-board communication device of a passing travelling carrier;
transmitting, in first direction, the movement permission signal received by the passing travelling carrier from the ground-based communication device to all other travelling carriers moving within the work area via the data communication means provided to each of the travelling carriers; and
each of the travelling carriers within the work area moving on its own at the operating speed based on the received movement permission signal.

Abstract
A method for controlling movement of travelling carriers includes performing data communication between front and rear adjacent travelling carriers, an on-board communication device provided to the travelling carrier and performing data communication with a ground-based communication device, and the ground-based communication device sending a movement permission signal at one end of a work area to the on-board communication device of a passing travelling carrier; and transmitting the movement permission signal to all of the travelling carriers within the work area from the ground-based communication device via the on-board communication device and the data communication means.
