Method for identification of rolls and a device for its accomplishment.

摘要

In this publication an identification method is described, by means of which speed of an identification station at identifying and measuring of the diameter of paper rolls and similar objects can be indreased substantially. The invention is based on that, that device (15) for reading the identifier and sensor (7, 8, 23, 24) for measuring the diameter are mounted to unit (19) moving on vertical lead (18), and its position is tracked by position sensor (14). The diameter of the roll is detected by mechanical detector (7), that turns up when it contacts the surface of the roll enabling thus an uninterrupted movement of the unit past the measurement site. After the measurement of the diameter the identification unit moves to the center of the roll, inferred from the diameter, where device (15) for reading the identifier reads the identification code of the roll. During the return movement of the identification unit markings can be made on the end of the roll by an ink-jet printer.
