Radio-frequency identification arrangement for a chain conveyor for piece goods and chain conveyor having such a radio-frequency identification arrangement

Abstract

A radio-frequency identification arrangement for a chain conveyor for piece goods having a driven linked chain is disclosed, comprising a support rail elementfor guiding and supporting the linked chainin the region of the radio-frequency identification arrangement and a radio-frequency reading device or radio-frequency writing/reading devicefor performing contactless reading or reading/writing of information by means of a radio-frequency signal. According to the invention, the radio-frequency reading device or radio-frequency writing/reading deviceis disposed directly on a bottomof the support rail elementand facing an underside of the linked chain. For this purpose, the latter may be accommodated in a recess or cavity of the support rail element By means of the radio-frequency identification arrangement, an RFID tag, which is mounted on a workpiece or workpiece carrier, can be read or read and written to through the linked chain of the chain conveyor. Furthermore, a relatively short distance between the radio-frequency reading device or radio-frequency writing/reading device and the RFID tag may be accomplished and thus an advantageously low power of the radio-frequency signal used for identification.
