Abstract
An apparatus for encoding RFID tags includes at least one encoding device, for the transmission of signals from and/or to RFID labels carried by a belt slidable in a travel direction; primary drivers, for pulling the belt giving it a continuous forward motion at constant speed; and secondary drivers, suitable for locally varying the speed of the belt when an RFID tag is in the proximity of a transmission area, in such a way that said RFID tag stops for a predetermined time within said transmission area in absence of relative motion with respect to said encoding device.
Claims14
An apparatus for encoding radio-frequency identification (RFID) tags, comprising:
- at least one encoding device configured for receiving or transmitting signals from or to RFID tags carried by a belt slidable in a travel direction, the encoding device being configured to read stored data or send data to be stored on an RFID tag when the RFID tag is within a transmission area suitable for allowing the passage of radio frequency signals directed from the at least one encoding device to or from the RFID tag;
- primary driving means adapted to pull the belt giving the belt a continuous forward motion at constant speed;
- and
- secondary driving means that vary the speed of the belt when the RFID tag is in a proximity of the transmission area, in such a way that the RFID tag stops for a predetermined time within the transmission area in absence of relative motion with respect to the encoding device, in the travel direction of the belt, maintaining unchanged the travel speed of the belt due to the pulling imparted by the primary driving means.
A process for encoding radio-frequency identification (RFID) tags comprising:
- a) providing an encoding apparatus including at least one encoding device configured for receiving or transmitting signals from or to RFID tags carried by a belt slidable in a travel direction, primary driving means adapted to pull the belt in a continuous forward motion at constant speed, and secondary driving means that vary the speed of the belt when the RFID tag is in a proximity of the transmission area;
- b) by means of the primary driving means, continuously feeding the belt at a constant speed along a travel direction, so as to convey the RFID tags to at least one transmission area;
- c) while keeping the drive imparted by the primary driving means to the belt unchanged, varying the travel speed of the belt in a periodic and localized manner so that an RFID tag stops for a predetermined time within the transmission area, in the absence of relative motion with respect to the corresponding encoding device in the travel direction of the belt;
- and
- d) activating the encoding device in such a way as to receive or transmit signals from or to the RFID tag, until the RFID tag has received, transmitted or stored data intended to be exchanged with the encoding device.
