Synchronous control method of conveyed goods and conveyer to which goods are transferred

Abstract

Abstract PURPOSE:To improve the synchronism and transfer goods smoothly by detecting the conveyed goods just before they are transferred on a conveyer to find out if they are within a synchronous transferring lot and constructing to control the speed of conveyed goods to be within a synchronous range. CONSTITUTION:Advancing goods held between a vertical belt A are detected by a photoelectric switch PH1. At this stage, a time range M-N for the conveyer 2 to transfer goods synchronously is previously set to judge whether they are within a synchronous range. That is, when the goods pass within the range M-N, they can be conveyed as they are, but when they are out of the range M-N and pass Q, for instance, the speed is controlled from Q to R as a solid line (B) shows. The synchronism of the goods transferred to the conveyer 2 is checked and ensured by a photoelectric switch PH2. This construction permits to improve the synchronism and transfer goods smoothly.
