<p>PURPOSE:To make it possible to facilitate the build up of a conveyer line, by transmitting two signals, a preprocessed workpiece supply ready signal and a post processed workpiece supply ready signal as workpiece supply condition signals in tandem to one and the same working machine. CONSTITUTION:When a preprocessed workpiece supply enabling signal 35 is detected as an input by a block 1, a control device 31 temporarily makes a preprocessed workpiece wait in a stopper section 9 in association with a signal which is turned on when a demand is generated at any of 2 through (n). If the preprocessed workpiece is required to be fed to a stopper section 11, confirmation is made by sensors 17, 18 to diverge a shutter 10, and if the workpiece is fed to the downward side, the shutter 10 is diverged toward the opposite side. Further, when a signal 34 is turned on, if a post-processed workpiece is there in any one of stopper sections 12, 13, judgment is made in accordance with the preference in the order of arrival so as to turn on either one of the stopper sections 12, 13 so that the post-processed workpieces are fed to the downstream side. Thus, when the number of production lines is increased in a build-up manner, it is possible to line-up the production lines by logically superposing signals from blocks.</p> |
