Unstacking feeder for unstacking sheet materials

摘要

An unstacking feeder has a sheet stack transfer member (3) for transferring a sheet stack (1), which consists of a number of stacked sheet materials (1a), along a circulation transfer passage which passes a predetermined unstacking position. In order to separate individual sheet materials from a sheet stack in order, a floater (6) is selected and supplied automatically in accordance with the shape of the sheet materials by floater supply member (5,7,7d). Each unstacked sheet material is transferred to equipment in the subsequence stage, such as a transfer feeder by sheet material transfer device (11,10). During this time, each sheet material (1) separated by the floater (6) is transferred onto a sheet material transfer unit by a sheet material transfer member (9).
