Abstract
An automatic reading device for tracking a reel of thread having a tube provided with an RFID tag is provided. The automatic reading device has a reader suitable for exchanging information with the RFID tag by an antenna and an electronic system having a central processing unit. The automatic reading device has a reel handling support having a tip on which a plurality of reels of thread having the tube provided with the RFID tag are insertable in sequence. The tip is the antenna.

1-13. (canceled)
An automatic reading device for tracking a reel of thread comprising a tube provided with a radio frequency identification (RFID) tag, the automatic reading device comprising:
- an antenna;
- a reader connected to the antenna by a connection cable, adapted to exchange information with the RFID tag by the antenna;
- an electronic system connected to the reader, comprising a central processing unit;
- and
- a reel handling support provided with a tip on which a plurality of reels of thread comprising the tube provided with the RFID tag is insertable in sequence, wherein the tip is the antenna, and
- wherein the antenna comprises a head provided with an internal seat in which an antenna body is accommodated, the internal seat being closed at the rear by a screen.
A method for automatic tracking of a reel of thread comprising a tube provided with a radio frequency identification (RFID) tag, the method comprising at least the following steps:
- providing at least one automatic reading device comprising:
- an antenna;
- a reader connected to the antenna by a connection cable, adapted to exchange information with the RFID tag by the antenna;
- an electronic system connected to the reader, comprising a central processing unit;
- and
- a reel handling support provided with a tip on which a plurality of reels of thread comprising the tube provided with the RFID tag is insertable in sequence, wherein the tip is the antenna, and
- wherein the antenna comprises a head provided with an internal seat in which an antenna body is accommodated, the internal seat being closed at the rear by a screen;
- tracking each reel of thread inserted onto the reel handling support by a tracking algorithm;
- wherein said tracking algorithm is run by a computer and includes at least the following steps:
- a) at the start of loading of the reels of thread on the reel handling support, starting a counter that samples pulses of a clock;
- b) while loading the reels of thread on the reel handling support, sampling readings of each RFID tag by the antenna;
- and
- c) at the end of loading of the reels of thread on the reel handling support, switching off the counter and dividing counted clocks in step b) by the number of expected reels of thread, and defining clock ranges corresponding to each loaded reel of thread.
