An exemplary friction feeder includes a hopper configured to accommodate a stack of items, a drive assembly configured to engage and move an item from the stack in a feed direction, and a gate assembly. The gate assembly includes a curved elongate separating member extending in the feed direction and configured to separate the item from other items in the stack as the item passes in the feed direction. The separating member has an item engaging surface biased to a reference point.

The present disclosure is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for separating at least a sheet from a stack in a tray. A paper feed mechanism feeds paper that is separated from the stack by a stack separation mechanism to the cutter elements. The feed and separation mechanisms can be activated by rotation of the cutter elements. In one embodiment, the stack separation mechanism moves in an alternating manner between retracted and extended positions to disengage and engage and insert the stack to separate (with its edge) paper therefrom to feed to the feed mechanism for shredding. The paper stack separation mechanism can move in an non-undulating manner relative to the stack. A device for stripping stapled pages, a pivotable support plate, and pressure plate can also be used, as well as a number of sensors.

A sheet feeder, which is incorporated in an image forming apparatus, includes a sheet container, a sheet conveying member disposed facing a sheet stack that includes multiple sheet members loaded on the sheet container to separate an uppermost sheet member placed on the sheet stack from the other sheet members and to convey the uppermost sheet member, and a pressing member switchable between a pressing position to press the sheet stack from above and a retracted position to separate from the sheet stack.

A single sheet handling device (14a to 14d, 30, 200, 252, 270, 350) for the input and the output of rectangular single sheets (38) respectively into and out of a container (12a to 12d). These rectangular single sheets can in particular be banknotes (38). The single sheet handling device (14a to 14d, 30, 200, 252, 270, 350) has a feeding device with feeding elements for the sheet-by-sheet feeding of single sheets (38) and for storing these single sheets (38) in a stack (36) of single sheets in the container (12a to 12d). Further, the single sheet handling device has a separating device with separating elements for the sheet-by-sheet removal of single sheets (38) of the stack (36) from the container (12a to 12d). The feeding elements and the separating elements are arranged separately from the container (12a to 12d).

A sheet feeder includes: an attraction separation unit including an attraction belt stretched between rollers and facing the upper surface of a sheet bundle to attract an uppermost sheet thereof, rotatably supported by a support member at a position upstream of the attraction belt in a sheet feeding direction, and supporting the rollers to be released from the support upon contact of the rollers with the uppermost sheet via the attraction belt; and a swing device for swinging the attraction separation unit around the support member as a pivot to move the attraction belt between an attraction position and a feed position more distant from the sheet bundle than the attraction position, and swinging, after the uppermost sheet has been attracted to the attraction belt at the attraction position, the attraction belt to the feed position to be rotated to feed the uppermost sheet.

A sheet feeder attracts an uppermost sheet of a sheet stack of a plurality of stacked sheets, and feeds the sheet in a sheet feeding direction. The sheet feeder includes an endless belt, a charging device, and a control device. The endless belt is made of a dielectric material, passes over upstream and downstream rollers, and is disposed above the sheet stack to face the sheet stack. The charging device applies an alternating voltage to an outer circumferential surface of the endless belt to form thereon alternating charge patterns. The control device separately controls the respective rotation states of the upstream and downstream rollers to make a sheet contact surface of the endless belt go slack in sheet attraction and make the sheet contact surface of the endless belt taut with tension into a substantially flat surface in sheet conveyance.

Described herein is a system and device for singulating mail pieces during mail processing and sorting. A double inhibit mechanism, mounted opposite a feed belt assembly and having at least two degrees of freedom at its downstream end, can maintain contact with mail in the mail path while separating overlapping mail pieces and allowing only single pieces to pass thereby.

An ingestion assembly is provided for a singulating apparatus having a conveyor system for moving a stack of sheet material along a feed path. The ingestion assembly is spatially positioned above the conveyor belt and includes at least one singulating roller driven in a direction opposing the motion of the conveyor belt. The ingestion assembly comprises an assembly support rotationally mounting the singulating roller at a downstream end portion and pivotally mounting to the singulating apparatus at an upstream end portion. A movable guide mounts to the assembly support and is positionable relative thereto as a function of a force vector imposed on the guide by the sheet material. Additionally, the moveable guide includes a surface operative to guide the sheet material into a singulating interface which is formed between the singulating roller and the conveyor system. In operation, sheet material enters the throat of the ingestion assembly and contact is made with the moveable guide. When the force vector, imposed by the sheet material, is less than a threshold level, the guide assumes a first position operative to shingle sheet material in preparation for singulation by the singulating roller. When the force vector, is greater than the threshold level, movable guide assumes a second position operative to pivot the assembly support and increase the singulating interface. Consequently, sheet material having a larger thickness dimension may pass for separation by the singulation apparatus.

In a mailpiece feed device comprising a mailpiece-receiving deck through which motor-driven conveyor members pass and on which a stack of mailpieces stands, and a monitoring and control circuit for actuating said motor-driven members at a determined drive speed in order to enable said mailpieces to be extracted one-by-one downstream, there is provided a method of controlling said motor-driven conveyor members wherein the drive speed of said motor-driven conveyor members varies as a function of the weight of said stack of mailpieces standing on said mailpiece-receiving deck.
