Description

RFID tags, multi-recognized conveyors {RFID tags, multi-recognized conveyor}

RFID (Radio-Frequency Identification) technology is a technology for recognizing information at a short distance through a medium of radio waves, which requires an RFID tag (hereinafter referred to as a tag) and an RFID reader (hereinafter referred to as a reader). The tag consists of an antenna and an integrated circuit, which records information in the integrated circuit and sends the information to the reader via the antenna. This information is used to identify the tagged object. In other words, it functions like a barcode. RFID differs from bar code systems in that it uses radio waves instead of reading them using light. Therefore, it does not work at short distances like a barcode reader, it can read a tag from a long distance, and it can even receive information through an object in between. RFID can be classified as the power used. The RFID that reads and communicates the information on the chip with only the power of the reader is called passive RFID, and the semi-passive RFID tag has a built-in battery. The power is used to read the information, and the power of the reader is used for the communication. The active RFID uses the power of the tag to read the information on the chip and communicate the information. RFID can be classified into the frequency of radio waves used for communication instead of power. RFID, which uses low frequencies, is called Low-Frequency IDentification (LFID), which uses 120-140 kilohertz (khz). High-Frequency IDentification (HFID) uses 13.56 MHz (Mhz), and UHFID (Ultra High-Frequency IDentification), which uses higher frequency, uses radio waves in the 868 to 956 MHz band.

Currently, RFID technology is used in a wide variety of fields. It is widely used to record personal information by attaching a tag to a passport or identification card from the track record of athletes or the trace of production history of a product. RFID is also used in toll road toll collection systems and transportation cards called "high passes." They can also be used to implant tags into animal skins for wildlife conservation or livestock care. In Osaka, Japan, tags are attached to bags and clothes of elementary school students, and RFID is also used to control access to buildings through identification cards. Sometimes tags are implanted in the human body. The Mexican Attorney General implanted tags in the bodies of 18 office workers and used them to control access to confidential archives. In addition, VeriChip, an RFID company, implanted RFID chips in 18 diabetics at the Atlanta Diabetes Expo, and RFID readers were sent to hospitals when the patients were unconsciously or unable to communicate. By scanning the RFID chip inside the body, we can retrieve detailed information about the patient from the database. RFID can be used in the future. In particular, RFID has attracted attention as an alternative to barcodes. Because RFID tags use integrated circuits as memories, they can contain more information than barcodes that record information in simple shades. So instead of just identifying the type of item, like a bar code, you can give each item a serial number. These features help you manage your inventory and prevent theft. In addition, the logistics system takes an effective way to shorten time by recognizing once per box.

In the present invention, in a conveyor system, a box to be recognized is easily trapped and recognized in a partition so that a large number of multiple tags in a box unit is recognized at a time so that the periphery of the box does not interfere with the tag.

In order to solve the above problems, using a rubber belt made of carbon, carbon nanotubes, or metal powder in the conveyor belt in the conveyor system, the rectangular shielding box made of metal can be transported up and down thereon. It is equipped with a recognizer on one side of the shielding box, place the box to be recognized on the conveyor belt, the shielding box is lowered, covering the box, crimped on the conveyor belt and cut off from the outside and recognized at once.

As seen above, the RFID tag multiple recognition conveyor of the present invention can greatly reduce the logistics time by recognizing all the boxes at the same time on the conveyor.
