Title:
METHOD AND DEVICE FOR SEPARATING SHEET
Document Type and Number:
Japanese Patent JPS6270129
Kind Code:
A
Abstract:
A carriage 22 having registration arms 160 resiliently coupled thereto is rotated toward a lowermost sheet of a stack stored in a hopper 200. The carriage 22 bears both a positive pressure-communicating port 54 and two bellows-type sucker cups 56A, 56B. Positive pressure fluid is applied through port 54 in a manner whereby at least a portion of sheet 220 is attracted to a surface 52 in which port 54 lies. While positive pressure fluid is being applied, the carriage 22 is rotated away from the storage position of the sheet 220, thereby deflecting at least a portion of the sheet about a first axis 208 of the sheet 220. Negative pressure fluid is then applied through sucker cups 56A, 56B to attract the deflected sheet 220 onto the sucker cups (56A, 56B, thereby deflecting the sheet about the surface 52 and thus about a second axis 230 of the sheet. The carriage 22 is rotated further away from the storage position of the sheet 220, thereby further deflecting the sheet 220 about its first axis 208.
