<p>PURPOSE:To prevent production efficiency from its decrease due to a trouble, by instructing a robot to perform work by the amount of maximum three processes for the same workpiece in a single station when abnormality is generated in the preceding and following stations. CONSTITUTION:A workpiece, fed in a conveying line 50 to the first - fourth stations 11-14, is discriminated by visual sensors 21-24 and control parts 41-44 for whether or not work is finished in the preceding process, self process and the following process, and work in robots 31-34 is performed in every tack time by a central control part 60. In each of these stations 11-12, work contents of the preceding and following processes in addition to the self process are instructed, and if a trouble is generated in the preceding and following stations, the control parts 41-44 give an instruction by the instruction of the central control part 60 to the robots 31-34 so as to perform the work by the amount of maximum three processes for the same workpiece in the single station. In this way, the production efficiency can be prevented from its decrease preventing the line from stopping till the trouble is recovered.</p> |
