Abstract
A carriage conveying system having a conveyance control device, which outputs communication signals for supplying a carriage with electric power by a feeder cable arranged along a guide rail to move the carriage along the guide rail and for controlling operation of the carriage. A control device transmits the communication signals to the carriage by the feeder cables. The carriage has a driving device for driving the carriage in accordance with the electric power. A controller controls the driving device in accordance with the communication signals. A communicating device receives the communication signals from the feeder cable for conveyance to the controller. The communicating device is located in the vicinity of the feeder cable.
Claims25
