ABSTRACT:
A delivery apparatus for a sheet-fed printing press includes a holding member, a delivery chain, at least two sheet stacking units, an engaging member, and a switching unit. The switching unit selectively switches a sheet release position where the engaging member abuts against the holding member and a retreat position where the engaging member does not abut against the holding member. The switching unit includes an air cylinder having a movable actuating rod, a first lever, having two ends pivotally mounted on the actuating rod and the engaging member, respectively, for coupling the actuating member and the engaging member, and a second lever having one end swingably supported and the other end swingably and pivotally mounted on a coupling portion between the actuating rod and the first lever. The first and second levers are located substantially on a straight line when the engaging member is at the sheet release position.
