Hopper loader

摘要

A hopper loader interfaced with a variety of hoppers/feeders having a horizontal infeed conveyor with a hand-feed belt section near the input end movable between an operative position for hand-feed operation and a lowered position to facilitate automatic feeding. A positioning actuator is coupled between the hopper loader and the hopper to provide for automatic fine-tuning adjustment of the jogger position as well as for machine make-ready to accommodate changing product size. A single controller is provided for simultaneously positioning a plurality of loaders. The controller has adjustable stops for accommodating frequently used product formats. Automatic air delay shut-off saves energy by shutting off the air blast system a predetermiend delay after the loader is halted. further automatic means saves energy and prevents "over jogging" and damage to the product by turning off the jogger a predetermined delay interval after the loader stops. One or a plurality of side guides adjustable by a single operating handle facilitate accurate and horizontal product alignment over the entire length of the loader. A feed rack having two swingable sections coupled through a center pivot enables removal of one section for attachment to a loader. The loader control panel is swingable mounted to a boom facilitating movement of the control panel to either side of a loader. A beaver-tail joggr has an easy-to-use manually operated fine-tuning adjustment assembly for facilitating rapid and precise adjustment thereof.
