Definitions

  • a lens held (chucked) by lens chucks is rough-processed by a roughing grindstone. Thereafter, the lens is finished to process by a finishing grindstone (refer to, for example, USP6283826 ( JP-A-11-333684 ).).
  • a finishing grindstone (refer to, for example, USP6283826 ( JP-A-11-333684 ).).
  • FIG. 1 shows an overview of an eyeglass lens processing apparatus and a cup attaching apparatus according to the invention.
  • a carriage portion 100 is mounted on a base 170. Further, the processed lens LE is chucked by lens chucks 102L, 102R provided to a carriage 101 constituting the carriage portion 100. A peripheral edge of the lens LE is processed by controlling distances of the chucks 102L, 102R relative to a grindstone group 162 attached to a grindstone spindle 161 and rotated by a motor 160.
  • the grindstone group 162 is constituted by a roughing grindstone for plastic 162a, a bevel-finishing and plane-finishing grindstone 162b and a polishing-finishing grindstone 162c, a roughing grindstone for glass 162d.
  • the support base 140 is fixed with shafts 156, 157 extended in a Y-axis direction (a direction of varying distances between axes of the lens chucks 102R, 102L and the grindstone spindle 161).
  • the carriage 101 is mounted on the support base 140 along the shafts 156, 157 movably in the Y-axis direction.
  • the support base 140 is fixed with a Y-axis moving motor 150. Rotation of the motor 150 is transmitted to a ball screw 155 extended in the Y-axis direction. Further, the carriage 101 is moved in the Y-axis direction by rotating the ball screw 155.
  • cup holder 31a provided at the cup attaching apparatus 1 is formed with an inserting hole and a key similar to the cup holder 130. Shapes thereof are similar to those of the cup holder 130, and therefore, an explanation thereof will be omitted.
  • the upper portion of the screen is displayed with left and right selecting keys 214R, 214L as means for selecting which of left and right lenses the lens LE to be processed is.
  • a display area of the key 214R is displayed by red color.
  • a color at inside of the target lens shape diagram FTR for the right eye is displayed (including a case of approximate color).
  • insides of the key 214L for selecting the left eye and the target lens shape diagram FTL for the left eye are fixed by a color the same as that of a background of the screen.
  • the operator confirms the colors and the colors of the cups 25R, 25L fixed to the lens LE. Thereby, it can visually be confirmed easily which is the lens LE to be held by the lens chuck shafts 102R, 102L. That is, when the right eye is selected, insides of the display area of the selected key 214R and the target lens shape diagram FTR for the right eye are displayed by red color. Therefore, the lens LE attached with the cup 25R of the corresponding red color may be mounted to the cup holder 130 of the lens chuck shaft 102L. When the left eye is selected, insides of the display area of the selected key 214L and the target lens shape diagram FTL are displayed by green color.
  • the lens LE attached with the cup 25L of green color in correspondence with the color may be mounted to the cup holder 130.
  • a failure of mistaking left or right of the lenses LE can significantly be reduced.
  • display colors of insides of the display areas of the selected keys 214R, 214L and the target lens shape diagrams FTR, FTL as the information of identifying left and right lenses displayedbased on selecting left and right lenses are displayed in correspondence with coloring the cups 25R, 25L. Therefore, optical recognizability can considerably be improved and the left and right lenses can easily be identified.
