Abstract
In order to efficiently detach and collect an IC tag (1) from a paper sheet (2) to which the IC tag (1) is attached, the IC tag (1) is detached from the paper sheet (2) by applying external force to the adhesive surface between the paper sheet (2) and the IC tag (1) (detachment step). Next, the detached IC tag (1) is fractionated from other substances (fractionation step).
Claims7
A system for detaching and collecting an IC tag from a paper sheet to which said IC tag is attached, comprising:
- a unit for swelling said paper sheet by soaking said paper sheet in a swelling liquid in which paper and/or an adhesive is soluble;
- a detacher for detaching said IC tag from said paper sheet by applying an agitating stream of the liquid to an adhesive surface between the swollen paper sheet and said IC tag in the liquid, to agitate and separate said IC tag from said paper sheet, and to decompose the paper sheet into paper components;
- and
- a fractionator for fractionating the detached IC tag from the paper components from said detacher, wherein
- said swelling unit pours the liquid, in which said paper sheet and said IC tag are soaked, into said detacher.
