Title: Drug subdividing apparatus
Inventor: YUYAMA SHOJI
IPC: B65B9/08
Filed: 2000-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent edge wear or damage of a sheet from occurring by performing strain relieving control for tension of the sheet even in the case of a sudden variation of tension according to the decrease of a diameter of rolled paper when the sheet is fed from the rolled paper in a paper feed unit to a subdividing unit. SOLUTION: When a sheet S is fed from rolled paper R in a paper feed unit to a heating roll 6 in a subdividing unit to subdivide drugs, a drug subdividing apparatus performs brake control at a control unit for the feed of the sheet S by means of a first angle sensor constituted by combining a plurality of Hall element sensors 25 provided to a support shaft of the rolled paper R and a plurality of magnets 24 provided to a core tube of the rolled paper R, respectively, and a second angle sensor comprising a proximity switch 26 provided on a support board of the support shaft and a protrusion. The control unit employs one of respective signals from both the first and the second angle sensors as a reference signal and determines deviation of the rolled paper with respect to a hollow shaft from a variation of the other signal.  The control unit performs the strain relieving control of a braking means by producing a control signal in response to the deviation and carries out the adjustment of tension relief, even in the case of a sudden variation of tension, so as to prevent edge wear or scuffing of the sheet from occurring in subdividing work.
