<p>A de-stacking unit shown generally at (1) has a conveyor belt (2) on which are mounted projections (3). Each of the projections (3) comprises a blade member having a leading edge (4) which is substantially normal to the surface of the belt (2), and a trailing support edge (5). The belt (2) is driven by a pulley or wheel (6) and the belt (2) is arranged to extend around a nylon support (7) positioned to the side of the pulley (6). The support, commonly referred to as a follower, is pivotally mounted about the centre of the drive pulley (6). The de-stacker unit (1) is positioned below a substantially vertical stack of biscuits (8) held in a magazine (9). The position of the drive pulley (6) is arranged such that clockwise rotation of the pulley (6) results in a left to right movement of the portion of the belt (2) beneath the magazine (9). The support (7) is mounted relative to the pulley (6) such that the portion of the belt (2) directly below the stack (8) of biscuits is angled downwardly with respect to the stack (8). In addition, the profile of the support (7) is such that the portion of the belt (2) directly below the stack (8) of biscuits is substantially flat.</p> |
