Digital printing and position measurement of RFID labels

Task

1. Separation, feeding, position checking of different plastic cassettes, in-process control
2. Digital online printing of 2 different label formats using DOD printing process
3. Code checking and printing registration checking before application of both labels to the cassettes
4. Automatic application of the labels to the sides of the cassettes on the fly, with across-corner application of one label in feed direction 
5. Feeding, UID reading, inscription, logging of RFID labels and application in a precise position in an indentation on the upper surface of the cassette 
6. Position measurement of the RFID label on the cassette using a camera system
7. NOK rejection with counter checking of rejects

Features

• Cycle output: 95 cassettes/minute
