Problem: When multiple automated lines are used for production, there is no simple way of standardizing and maximizing the production volume of each line. It is also difficult to determine the operating condition of each automated machine. In a production system where the work results and inspection results from the preceding process are used to determine which automated line the product will be sent to for the next process, control by the host computer is difficult, and errors are extremely troublesome to handle.
Mount a Data Carrier (ID Tag) to each pallet, write the work data for the automated machine (automated machine number used, lot number, tool used, work program number, etc.), and use this to send the product and components to an available line. The instructions are read by each automated machine, and the work is done. The work start time and end time are written to the Data Carrier. For inspection processes, the inspection results are written together with the automated line number that should be used next, and the subsequent work is done at that automated line.
The V600-D8KR04 Data Carrier with a communications distance of 10 cm enables communication from below a roller conveyor, through the roller intervals. For this, the Data Carrier is embedded in the bottom of the pallet. The large data capacity of 8 Kbytes allows storage of detailed work instructions and inspection data. The large-capacity, shielded-type V600-D8KR1/R04 Data Carrier can be directly mounted to metallic pallets. High resistance to noise enables stable communications in FA environments.
Because the product can be sent to an available line based on the data in the Data Carrier mounted to the pallet, control is simplified with no burden on the host computer. This makes it possible to optimize and standardize each automated line to dramatically increase productivity. Further, by inputting time control data to the Data Carrier, the operating condition of the lines can be easily obtained. Because the product proceeds to the next process according to instructions that were written to the Data Carrier immediately before, no mistakes occur in tracking control when interrupt items are inserted, and operation is efficient with no burden on the host computer.
