Abstract
The disclosure relates to a stacker tyer for stacking newspapers received in a shingled stream from a printing press. A single centrally located stacker mechanism is flanked by a pair of compensators and outside of the compensators is a pair of tyers. Stacks are built in the stacker and moved laterally first to a compensator and then to a tying mechanism. Outside the tying mechanism are located a pair of delivery mechanisms which deliver the tied stack for further processing. The stacker is able to form either short stacks (bundles) or tall stacks (logs). In the case of bundles, the bundles may be either compensated or uncompensated; compensated logs are not built.
Claims23
An apparatus for receiving a continuous stream of sheet-like articles and for forming the stream into either short or tall stacks, said apparatus comprising a frame, a platform for supporting the bottom of a stack, deflector means connected with said frame for causing one of an incoming stream of sheet-like articles to drop onto said platform and for causing each succeeding incoming sheet-like article to pile up to form a stack on top of said one sheet-like article, means for guiding said platform in said frame along an inclined stacking path, means for moving said platform along said stacking path from an uppermost position in which said platform receives said one article downward to a lowermost position as the succeeding articles pile up, a stack support for receiving stacks from said platform, means for connecting said stack support with said frame adjacent the lowermost portion of the stacking path of said platform for receiving tall stacks from said platform, and means for connecting said stack support with said frame at a location between the uppermost and lowermost portions of the stacking path of said platform for receiving short stacks from said platform.
An apparatus for receiving a stream of sheet-like articles, forming the sheet-like articles into stacks and tying the stacks, said apparatus comprising stacking means for receiving an incoming stream of sheet-like articles and for building a series of stacks of said articles from said stream, first and second tying mechanisms for tying said stacks, said first and second tying mechanisms being located on opposite sides of said stacking means, and transfer means for moving each succeeding stack of said series of stacks laterally and alternately toward one or the other of said tying mechanisms and for maintaining the sheet-like articles forming each of said stacks in alignment while being moved toward one or the other of said tying mechanisms.
An apparatus for receiving a stream of sheet like articles, forming the sheet like articles into stacks and tying the stacks, said apparatus comprising stacking means for receiving an incoming stream of sheet like articles and for building a series of stacks of said articles from said stream, said stacking means including a frame, a platform for supporting the bottom of a stack, deflector means connected with said frame for causing one of the incoming stream of sheet like articles to drop onto said platform and for causing succeeding incoming sheet like articles to pile up to form a stack on top of said one sheet like article, means for guiding said platform in said frame along an inclined stacking path, means for moving said platform along said stacking path from an uppermost position in which said platform receives said one article downward o a lowermost position as the succeeding articles pile up, stack support means for receiving stacks from said platform, means for connecting said stack support with said frame adjacent the lowermost portion of the stacking path of said platform for receiving tall stacks from said platform, and means for connecting said stack support with said frame at a location between the uppermost and lowermost portions of the stacking path of said platform for receiving short stacks from said platform, first and second tying mechanisms for tying said stacks, said first and second tying mechanisms being located on opposite sides of said stacking means, and transfer means for moving each succeeding stack of said series of stacks laterally and alternately toward one or the other of said tying mechanisms and for maintaining the sheet like articles forming each of said stacks in alignment while being moved toward one or the other of said tying mechanism.
