There are disclosed method and apparatus for stacking the output ("documents" or "printed products") of a high speed printing press or bindery line. The documents are shingled on a linear infeed conveyor where they are also aligned, positioned, and counted, all at high speed. When the amount of documents desired for a stack have been counted or weighed or determined by stack size or height, further document flow is temporarily interrupted. The documents are speeded up in an accelerator to reduce the amount of shingling. They are ejected from the accelerator to glide through the air onto a stack starter surface which slowly descends as the stack is formed. The partially completed stack is transferred to a de-elevator and the stack starter returns to begin building a new stack. The de-elevator lowers the completed stack onto a receiving surface and rises to receive the next partially completed stack from the stack starter surface. A pusher then removes the stack from the receiving surface.
The method of forming a plurality of stacks each containing a predetermined amount of printed products from a plurality of printed products being advised in aligned and shingled relationship on a substantially horizontal linear conveyor, said method comprising the steps of:
Apparatus for forming a plurality of document stacks capable of operating at a rate of at least 18,000 documents per hour from a plurality of documents advancing in aligned and shingled relationship on a substantially horizontal linear conveyor comprising:
A stacking method for forming a stack of printed products from a multiplicity of printed products moving forward at speed in a downstream direction in shingle overlap relationship being fed along a conveyor, said stacking method comprising the steps of:
Apparatus for building a stack of printed products from a multiplicity of printed products being conveyed forward by an infeed conveyor at speed in overlapping shingled relationship comprising:
The method of forming a neatly aligned vertical stack of printed products moving at a relatively high constant speed in shingled relationship with each printed product having a forwardly facing edge comprising the steps of:
The method of forming a neatly aligned vertical stack of printed products moving at a relatively high constant speed in shingled relationship with each printed product having a forwardly facing edge comprising the steps of:
