Title:
ROLL PAPER FOR PARTIALLY WRAPPING DRUG
Document Type and Number:
Japanese Patent JP3243241
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To detect the winding amount of sheet with an angle sensor in a drug partial wrapping device capable of feeding a sheet smoothly without causing any abrupt variation in sheet tension of a paper roll and thus eliminating a rubbing or rupture from being produced.
SOLUTION: A drug partial wrapping device which feeds a sheet from a sheet feeding part to a partial wrapping part and partially wraps drug comprises a rotary encoder 32 as a length measurement sensor on a sheet feeding route and a hole element sensor 25 as an angle sensor on a pivot shaft so as to detect the winding amount of paper roll based on a variation in a signal from each of these sensors. The drug partial wrapping roll paper used for the drug partial wrapping device is formed of the paper roll R wound on a hollow signal pipe P, and a magnet 24 is disposed in a hollow core pipe P so that the winding amount of paper roll is detected by the angle sensor.
