<p>PURPOSE:To enable control of classification without requiring a pulse generator, by providing a synchronous signal to a classification controller in article classification control section based on a signal fed from a photo-optical switch for detecting moving condition of a classifying truck. CONSTITUTION:A photoelectric detecting section 1 is arranged perpendicularly with advancing direction of a reaction plate in a classifying truck and provides a classifying truck detection pulse. A synchronization detecting control section 4 detects moving condition of the classifying truck based on a detection pulse fed from the photoelectric detecting section 1, and provides an abnormal classifier speed signal Q, a synchronous signal R and a speed indication signal S respectively to a classifier control circuit 16, a classification controller 17 and a linear motor controller 18 corresponding to the moving condition. Consequently, classification control of the classifying truck can be made even when a pulse generator can not be arranged in driving section.</p> |
