摘要:
In a mailing machine where an envelope feeder is used to feed envelopes one at a time into a mail inserter and an insert feeder is used to move insert material into the envelope in the mail inserter for mail insertion, a suction cup assembly having two suction cups is used to keep the throat of the envelope in the mail inserter open. Each suction cup is movably mounted on an air actuated holder so as to allow the suction cup to move up and down to open the envelope throat. The suction cup assembly is movably mounted on a mounting stand in the mail feeder at a pivot so that the suction assembly can be rotated at the pivot so as to deflect the suction cups further away from the insert feeder if a jam involving the insert material or the envelope occurs.

A rotatable pneumatic feeding head having a vacuum shoe with apertures for picking up an envelope from an envelope stack by negative air pressure. The feeding head has an outer cylinder with holes communicating with the apertures, and an inner cylinder with cutout regions operatively connected to a vacuum pump. The inner cylinder and the outer cylinder are rotated independently of each other such that when they are aligned, a negative pressure is created at the apertures through the cutout regions and the holes. When the inner cylinder and the outer cylinder are out of alignment, the negative pressure is cut off from the apertures. The vacuum shoe is removable so that it can be repaired or replaced when it is damaged or worn.

An envelope hopper having a plurality of bottom rods to form a supporting surface for supporting a stack of envelopes and a paddle to push the envelopes towards an envelope feeder at the downstream end. A scrub wheel is rotatably mounted on a fixed, rotation axis on the paddle and is in contact with one of the bottom rods. The rotation axis of the scrub wheel is oriented at an angle relative to the rotation axis of the contacting rod, so that when the contacting rod rotates, it causes the scrub wheel to rotate, thereby producing a force on the paddle urging the paddle to move towards the downstream end. Preferably, the envelope hopper has a side rod on one side of the envelope stack, and the supporting surface is tilted from the horizontal surface, so that the envelopes are moved towards the side rod by gravity in order to register against the side rod. Preferably, the side rod also rotates in order to reduce the friction between the envelope stack and the side rod.

A method and apparatus are for decelerating a sheet of paper in a paper-cutting system. The sheet of paper is cut using a cutter, and the sheet is then accepted into a take-away nip. The take-away nip is operated at an initial rate in order to move the sheet of paper away from the cutter at an initial speed. The take-away nip is then operated at a rate decreasing to a final rate, in order to decelerate the sheet of paper to a final speed by the time the sheet of paper exits the take-away nip. The take-away nip is subsequently operated at the initial rate again, prior to accepting another sheet of paper at the initial speed.
摘要:
A method for creating mailpieces from a single web of printed material. The web of printed material includes printed matter to be used on envelopes, and other printed matter to be used on mail content to be included in the envelopes. The method starts with cutting consecutive sections of the web into separated sheets. Some of the separated sheets are envelope sheets including envelope printed matter, and some of the sheets are mail content sheets including mail content printed matter. The method includes cutting variable sized sheets depending on whether a sheet is a mail content sheet, or an envelope sheet. The method further includes cutting variable sized envelope sheets depending on the size of the mailpieces.

A system for conveying mailpieces along a conveyance path and singulating a mailpiece from a stack of mailpieces along the conveyance path. The system includes a first conveyance for conveying mailpieces at a variable velocity and a second conveyance, downstream of the first conveyance, for conveying mailpieces at a constant velocity along the conveyance path. A series of optical sensors extends from the first to the second conveyance and is operative to issue a gap signal indicative of the relative spacing between sequential mailpieces along the conveyance path. A processor is responsive to the gap signal and is operative to control the first conveyance to decrease the relative spacing between sequential mailpieces when the gap signal exceeds a threshold value.

A paper cutting system includes a cutting assembly, a transport moving a web through the cutting assembly, a vacuum plenum utilizing a vacuum source to control the web moving through the cutting assembly, an air source providing purge air to the cutting assembly for removal of debris, and a heat exchanger normalizing a temperature of the purge air with respect to a temperature of ambient air prior to the purge air reaching the cutting assembly. The heat exchanger may be operated using the vacuum source.

System and methods of controlling a plurality of motors based on a motor motion attribute, such as rotor position, velocity, or acceleration, which simulate the properties of a mechanical differential, including a pure differential, a limited slip differential, and/or a locking differential. The method may be employed in a number of applications, including, without limitation, a paper handling system, such as an inserter, to control the nips of a pinless cutter of an inserter, and in a vehicle.

A system for detecting wear in a gripper chain of a chain conveyor is provided. The system includes an optical sensing system having a detection path located vertically beneath a portion of the gripper chain at a predetermined location. The detection path is located such that, when the gripper chain becomes elongated and droops a predetermined amount due to wear of the gripper chain, the sensing system senses the presence of the gripper chain in the detection path.
