  • Patent number: 6776572
    Abstract: For stacking flat articles (2), a stacking shaft (10) including a pusher (11) for removing stacks from the shaft is used and for supplying the articles (2) into the stacking shaft (10) a supply support (12) is used. The supply support (12) is oriented towards the opening of the stacking shaft (10) at an inclination from above and the completed stacks (1) are pushed out in a direction opposite the supply direction. With this arrangement, it is possible to resume the supply operation after an interruption necessary for the pushing-out, before the stack (1) is pushed out of the stacking shaft (10) completely, and thereby results in very short cycle times. The stacking method is suitable in particular for stacking folded printed products being supplied in the supply stream parallel to their folded edges.

  • Patent number: 6655903
    Abstract: The invention considerably reduces the danger of deformation for containers made from a thermoplastic material during the transfer to a stacking magazine or into a locally fixed catch plate. This deformation danger results from the fact that the formed stack must be displaced within a short time by the stack distance, either through the transferred containers themselves or by components of a catch plate that is moved forward with each cycle. This is achieved through displacing the stacks in the stacking magazines or the locally fixed catch plate with a displacement device. The displacement device can be combined with the stack removal device or can be a separate displacement device. According to a modification of the invention, the method is intended to improve the cooling of the stacked containers.

  • Patent number: 6499731
    Abstract: A high speed sheet feeder machine includes at least one pusher that follows a loop-shaped path of travel as the machine operates. The pusher pushes an insert into an envelope during a forward and downward part of its path of travel and then retreats rearwardly and upwardly along the loop-shaped path of travel before repeating an insertion. In this way, the pusher makes no abrupt changes in its path of travel. Very high rates of insertion are made possible by providing multiple pushers at longitudinally spaced apart intervals along the loop-shaped path of travel. A stop plate is integrally formed with each pusher assembly and a fixed position barrier is mounted on the machine adjacent the rearward end of the loop-shaped path of travel to prevent over-rotation of each pusher member at very high speeds.

    Abstract: A method and apparatus for stacking articles in a side-by-side stack and feeding the stacks to a discharge conveyor. Articles such as video cassette containers or CD containers, are conveyed in an upright singulated fashion by a guide arrangement. Each individual article enters a transfer location where it is supported by a transfer platform. A pusher device extends to push the article from the transfer location onto a support platform. The support platform supports the individual articles as they are assembled into a stack. After the pusher device has been retracted, a hold-back member is extended to support the outermost article of the assembled stack. Once a stack of articles has been assembled, a stack pusher assembly pushes the stack off of the support platform and onto an outfeed conveyor assembly. A back-up slide assembly supports the outermost article of the stack as the stack is assembled by the stacker mechanism.

    Abstract: A method for forming vertical stacks of documents and then conveying the stacks serially along a conveyor to further processing stations. The stacks are rapidly ejected onto a conveyor which is driven at a relatively slow delivery speed, and to avoid longitudinal shingling of the stacks caused by their rapid ejection onto the conveyor, and to correct any lateral misalignment of each stack, there is provided a pair of rotatably mounted resilient guide rolls along respective opposite sides of the conveyor for rotation about vertical axes. The rolls are spaced apart a distance such that the rolls resiliently engage the opposite sides of the stacks as they pass therebetween. Also, the guide rolls are rotated at an initial peripheral speed which closely approximates the speed of the advancing stacks when the stacks engage the two guide rolls, which serves to square the stacks.

    Abstract: A retractable arm serves as a combined pushing mechanism and dead plate for holding and moving articles that have been stacked onto an accumulation tray for a stacking station in an article sortation conveying system. The stacking station stacks articles sequentially onto the accumulation tray standing upright on edge and in series side-by-side. While the articles are being stacked, the retractable arm is positioned in the down position and positioned so that a first side of the arm holds the articles on edge without tipping, much like a bookend. A linear motion actuator, preferably a pneumatic cylinder, moves the retractable arm along the length of the elongated accumulation tray. During the stacking procedure, the pneumatic cylinder is deactivated (i.e. a dead cylinder), and the stacked articles push the retractable arm incrementally along the accumulation tray towards an unloading area.

  • Patent number: 6231299
    Abstract: An apparatus for forming vertical stacks of documents and then conveying the stacks serially along a conveyor to further processing stations. The stacks are rapidly ejected onto a conveyor which is driven at a relatively slow delivery speed, and to avoid longitudinal shingling of the stacks caused by their rapid ejection onto the conveyor, and to correct any lateral misalignment of each stack, there is provided a pair of rotatably mounted resilient guide rolls along respective opposite sides of the conveyor for rotation about vertical axes. The rolls are spaced apart a distance such that the rolls resiliently engage the opposite sides of the stacks as they pass therebetween. Also, the guide rolls are rotated at an initial peripheral speed which closely approximates the speed of the advancing stacks when the stacks engage the two guide rolls, which serves to square the stacks.

  • Patent number: 6209865
    Abstract: In a device that ejects one or more sheets of media to a moveable, remote output storage location, a method and apparatus for improving output stack quality is described. An invented stack holder holds previously-ejected sheets in place, so that the ejection of a newly-accumulated job does not cause misalignment of the stack by pushing the paper that it contacts during its movement. The preferred stack holder(s) each have an arm that extends down from a part of an accumulator and have a friction pad or area near its end. The system logic causes the stack tray to move up until the top of the output stack is sensed to be at a location that means it is abutting against the stack holder(s). In this position, the stack holder(s) place enough downward pressure on the top sheets of the output stack to hold the top sheets in place while an accumulated job is rejected onto the output stack.
