<p>PURPOSE:To obtain the article conveyance system which is not affected even when a travel path is blocked by grasping the current position of an article conveying means from the standstill position confirmation signal of the article conveying means. CONSTITUTION:The article conveyance system stored the travel path of the article conveying means 1, so a timing signal for rotating travel wheels 6 is sent to the movement signal reception part 3 of the article conveying means 1 for a travel from 19-4 to 19-5. The moment the electric motor of a travel driving means 5 stops, a signal is outputted to the oscillation circuit of a standstill signal transmission part 2 and a light emitting element emits light, which is converted photoelectrically by a standstill signal reception part 8 into an electric signal. This signal is sent to a central control part 13, which judges and stores the place of a confirmation reception signal from which the signal is received and outputs a signal for displaying the current position of the article conveying means 1 on the console panel of a movement command part 12.</p> |
