NO-FEED-ROLL CORRUGATED BOARD OR PAPERBOARD SHEET FEEDER RETROFIT APPARATUS AND METHOD

摘要

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus (200) is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface (210) for boards (e.g., 2) having drive wheels (222 W, 224W, 226W) in an initial variable velocity zone (220) which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone (230) which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder (200) also includes a controller (300) configured to receive predetermined velocity signals from the host machine (10) and generate (i) a first initial variable velocity control signal for initial variable velocity zone (220) and (ii) a second velocity control signal for second velocity zone (230) in response.
