Abstract
Newspapers and other printed matter fed from a printing press or inserting machine are generally folded or delivered in a continuous stream with the papers oriented in an overlapped or imbricated relationship. The stream of papers are received and stacked by the stacking apparatus or stacker which must operate at high speeds. The stacker orients the papers in the stacks and ejects the bundles of papers. The present invention relates to devices intended to reduce the prospects for inadvertent interference with the stacking mechanism or to reduce the potential for injury.
Claims20
A stacking apparatus for assembling a stream of printed products, said stacking apparatus comprising:
- a frame having at least one opening through which a bundle is selectively ejected;
- a table assembly;
- a bundle ejection mechanism that selectively ejects a bundle of printed product from said table assembly;
- and,
- at least one guard assembly operatively associated with the frame opening.
A stacking apparatus for assembling a stream of printed products into bundles comprising:
- a frame having at least one discharge opening dimensioned to allow a bundle to pass therethrough;
- a turntable assembly;
- a drive assembly reciprocating and rotating said turntable assembly, and selectively ejecting a bundle from the turntable assembly;
- and
- a guard assembly operatively associated with the discharge opening.
The stacking apparatus of claim 112, wherein said guard assembly is comprised of a panel hingedly connected to said frame.
An opening guard mechanism incorporated into a stacking apparatus for assembling a stream of printed products, said stacking apparatus comprising:
- a frame;
- a turntable assembly housed in the frame;
- a drive assembly which reciprocally rotates said turntable assembly;
- a bundle ejection mechanism for ejecting a bundle of printed product from said turntable assembly;
- at least one bundle ejection opening in the frame allowing selective ejection of a bundle of printed product from the turntable assembly;
- and,
- an opening guard allowing bundle ejection and preventing or detecting foreign object ingress to the bundle ejection opening.
