Definitions

  • the present invention relates to a method and system for measuring the thickness of a long sheet material such as a paper web (winding paper) or a plastic film manufactured by a paper machine or the like.
  • the width direction refers to the width direction of the long sheet material.
  • the width direction roll diameter refers to the roll diameter for each point in the width direction of the long sheet material.
  • the width direction profile (thickness unevenness or flatness along the width direction) of the long sheet material is reflected.
  • the linear laser beam irradiated on the winding roll is defocused or the distance from the light source changes as the roll diameter increases.
  • the linear laser beam is imaged twice within a certain time in the same field of view of the camera. In this case, the thickness and length of the first image and the second image change in addition to the position in the visual field. As shown in FIG.
  • the thickness measurement system for the long sheet material of the invention is such that the position of the reel drum is fixed, and the reel spool is movable in the flow direction as the roll diameter increases. i)
  • the roll diameter measuring device measures the amount of movement in the flow direction of the end surface of the reel spool based on the flow direction camera that images the rotating end surface of the reel spool and the image captured by the flow direction camera.
  • FIG. 3 shows a state of the winding device 10 immediately after the frame change.
  • a paper web W is wound around the next reel spool 22, and the separated take-up roll R is released from the secondary arm 26 and retracted downstream (flow direction) and then descends onto the rail 14. This takes several seconds, and the reel spool 22 has not yet entered the field of view of the flow direction sensor 104 of the flow direction moving amount measuring apparatus 100 described later.
  • the measurement result of the increase amount is measured as y instead of h.
  • the measured value to be obtained is the amount of change in the height in the width direction (roll diameter) during the movement, which is the amount of change in the height in the width direction at the reference position and the position after the movement.
  • a corrected measurement value is obtained by the following equation based on the radius r0 of the reference position, the measurement result y, and the flow direction movement amount x.
