<p>This invention concentrates on relieving the ergonomic strain on a bindery line operator by always loading at an ergonomically correct height for minimum wrist strain and also performing the 'jogging', which is normally done by the operator prior to placing a stack onto the pocket feeder. The signatures (240) are placed onto a lift at the same height because the signature stack support (45) is being lowered automatically until the pivoted conveyor is full. Then, the entire log is pivoted upwardly and advanced to meet the rear of the previously loaded log. The log is advanced through a series of air blasts to aerate the signatures (240), a vibrating table (125) to align the backbones, and a set of oscillating guides (165) to align the signatures head to foot to eliminate the manual jogging of signatures and thereby repetitive movement of the operator's wrist to do the jogging.</p> |
