Title:
CONTINUOUS SHEET TAKE-UP DEVICE
Document Type and Number:
Japanese Patent JP2017214173
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent tension applied to a continuous sheet from being too large by delaying the rotational speed of a take-up shaft when a take-up diameter of the continuous sheet to the take-up shaft becomes large and the take-up linear velocity becomes fast, and improve take-up quality by applying the proper tension to the continuous sheet regardless of the take-up diameter.SOLUTION: A continuous sheet take-up device 2 includes: a tension bar 36 which is provided on the upstream side of a take-up shaft 34 for taking up a continuous sheet CP issued from a printer 4 and applies tension with the self-weight to the continuous sheet CP; a position detection sensor which detects the tension bar 36 at a plurality of detection positions within a movement range of the tension bar 36; a rotational speed setting unit which delays the rotational speed of the take-up shaft 34 when the position detection sensor detects the tension bar 36 within the prescribed setting time while the take-up shaft 34 is being rotated; and a motor drive unit which rotates the take-up shaft 34 at the rotational speed set by the rotational speed setting unit.SELECTED DRAWING: Figure 1
