Abstract
There is described a unit (1) for forming/advancing at least one pack (3) or at least one portion of a pack 5 (3), comprising: a frame (12a, 12b), at least one carriage (14, 14b), which is movable along a path (13a, 13b) with respect to frame (12a, 12b) and is adapted to form/advance said pack (3) or said at least one portion of a pack (3), an electromagnetic stationary device 10 (50), at least one tag (52a, 52b) carried by carriage (14a, 14b), and wireless communication means (51) configured to establish a bidirectional communication between stationary device (50) and tag (52a, 52b).
Claims9
A unit for forming/advancing at least one portion of a pack, comprising:
- a frame;
- and
- at least one carriage configured to move along an endless path with respect to the frame and configured to advance the at least one pack portion, the carriage comprising at least one sensor configured to generate an output signal associated with at least one of an acceleration or a temperature of the carriage;
- an electromagnetic stationary antenna;
- at least one RFID tag carried by the carriage, the RFID tag configured to receive the output signal from the sensor and to power the sensor;
- and
- a communication unit configured to:
- establish wireless bidirectional communication between the electromagnetic stationary antenna and the RFID tag;
- and
- transfer the output signal from the RFID tag to the electromagnetic stationary antenna,
- wherein the electromagnetic stationary antenna has a shape substantially the same as a shape of the endless path.
A method for advancing at least a pack portion, comprising:
- advancing at least one carriage along an endless path with respect to a stationary frame;
- generating, by a sensor on the carriage, an output signal associated with at least one of an acceleration or a temperature of the carriage, wherein the sensor communicates with an RFID tag carried by the carriage and wherein the sensor is powered by the RFID tag;
- advancing the pack portion by the carriage;
- establishing a wireless bidirectional communication between an electromagnetic stationary antenna and the RFID tag carried by the carriage;
- and
- transmitting the output signal from the RFID tag to the electromagnetic stationary antenna;
- wherein the electromagnetic stationary antenna has a shape substantially the same as a shape of the endless path.
