DEVICE FOR SEPARATION OF THIN SHEET ARTICLES LAID IN STACKS AND THEIR PIECEMEAL DISCHARGE Russian patent published in 1997 - IPC

FIELD: devices for manipulation of thin sheet articles laid in stacks, applicable for separation and piecemeal feed of articles, for example, for attachment of labels to the surface of packages. SUBSTANCE: the device has a magazine with a stack of sheet articles, the magazine is made extensible, loaded from the top, movable around the separator roller axis. The pressure roll is installed on a spring-loaded pendulum. The sucking roller- separator is made in the form of a hollow sleeve with a gear ring with a supporting flange at the end, with a perforated flat on the cylindrical part, fitted onto a fixed axle with a through duct communicating with the perforation on the flat at gripping of the sheet article, and installed under the magazine edge in a position providing for parallelism of the flat in the initial position with the lower sheet article. The device is furnished with a conveying member made in the form of a perforated drum with a gear quadrant at the end, fitted onto a hollow axle, whose through duct provides for communication with the drum perforation, and kinematically linked with the roller-separator through a gearing. The pressure roll is installed for passive rotation on its axle and movement in parallel with the axle of the roller-separator in the mechanical trajectory of the pendulum. The device is also furnished with air distribution system. EFFECT: improved design. 2 dwg
