Abstract:
An inserter input system including a web feeder providing a web of printed material to be split by a web slitting knife along the web's direction of travel. The split web is then cut transverse to the direction of travel by a rotary cutter operating at a first velocity, resulting in side-by-side individual sheets. Downstream of the rotary cutter, a right angle turn mechanism receives each of the side-by-side sheets and reorients them by ninety degrees. Further the right angle turn reorients the sheets into a serial shingled arrangement. A high speed separation nip pulls individual shingled sheets out from the shingled arrangement. The speed of the separation nip is such that a predetermined gap between the previously shingled sheets is formed. In a further preferred embodiment of the present invention, the speed of the rotary cutter and right angle turn mechanism are controlled to adjust a quantity of sheets that would be generated from displacement traveled due to inertia during a deceleration of the system to a stop.
Abstract:
A method and system are disclosed for delivering and feeding a stack of paper to a high-speed sheet feeder. A sheet handling cart is removably connectable to a docking station attached to the high-speed sheet feeder. The sheet handling cart comprises a paper trough which is liftable from the rest of the cart. The paper trough has a trough bottom which longitudinally forms an elongated opening narrower than the bottom of the paper trough, the elongated opening being dimensioned to accommodate a conveyor belt that will protrude upward through the rectangular opening, after the paper trough is lifted from the rest of the cart, in order to advance the stack of paper toward the high-speed sheet feeder.
Abstract:
A buckle chute having a deflector disposed in front thereof to allow a sheet of document to enter the buckle chute channel or to deflect the sheet away from the channel. The deflector is pivotally linked to two actuator arms on the left and right sides of the buckle chute. Each actuator arm is pivotally linked to a bell crank, which is also pivotally linked to a linking member. The linking members are further connected to a lever such that they can be moved in opposite directions from left to right or from right to left so as to cause the bell cranks to rotate in opposite directions. As such, the actuator arms are simultaneously moved toward or away from the front side to control the deflector position.
Abstract:
The present invention concerns a document processing and collating machine having a feeding path leading to at least one document conveying devices having one or more document accumulating bins for receiving a series of documents that are fed downstream in spaced apart collations with documents in shingled relationship. The document accumulator bins have an intermediate conveying and diverting apparatus which is momentarily engaged to cause a leading end of a shingled collation of documents to be diverted into a document accumulating bin where the documents are registered at their common leading end at a nip of a set of downstream conveying rollers that are stopped during the registration process.
Abstract:
A method and system for sheet accumulating wherein a web of material is cut into groups of cut sheets and a right-angle transport device is used to collate the cut sheets into packets. Because the cut sheets in each packet are moved into and out of the right-angle transport device in separate paths with different pathlengths, the cut sheets overlap with each other by an overlapped amount as they exit the right-angle transport device. A path deflector having a curved path is used in at least one of the paths in order to reduce the pathlength difference, thereby increasing the overlapped amount.
Abstract:
A turnbar for use in a sheet accumulator having an accumulating assembly which causes sheets serially and separately entering an entry point to overlap each other to form a stack at an exit point. The turnbar is used to change the direction of the sheets at the entry point and the stack at the exit point. The turnbar can be disengaged from the accumulating assembly for jam clearance and maintenance purposes. Preferably, the turnbar has a securing mechanism for removably mounting the turnbar on the sheet accumulator.
Abstract:
A method and system for transporting envelopes from an envelope feeder to an envelope staging area in an envelope insertion machine. The envelope transport system includes two envelope bins and two envelope supply paths linking the envelope bins to an envelope feeder. Each of the bins is used to temporarily store an envelope before that envelope is moved to the staging area. The envelope supply paths are controlled by a flipper gate which alternately opens one path and closes another so as to allow an envelope to enter one envelope bin while another envelope in the other envelope bin is moved to the staging area. With the dual envelope bins connected to the dual supply paths to receive envelopes released by the envelope feeder, the envelope feeder does not have to slow down substantially in order to wait for the released envelope to clear the feeding path.
