A singling apparatus and a system for singling sheet material comprises a sheet store for receiving a sheet stack of sheets to be singled. The sheet store includes a singling gap, which is formed and arranged to deliver a sheet out of the sheet store to a transport mechanism. The singling apparatus comprises further a singling device comprising a rotating separation roller wherein the separation roller comprises partially on its rotational surface a contact area to periodically contact and transport the sheet from the sheet store to the transport mechanism. A position control device of the singling apparatus is coupled to the separation roller and comprises an alignment indication being in correlation with an angle position of the contact area of the separation roller and indicates the alignment of the contact area to the singling gap and/or the sheet.

The pick-up device disposed between the input tray and the feeding path and includes a Paper feeding unit for feeding the paper from the input tray; a separation roller disposed opposite to the Paper feeding unit and contacting each other; a blocking arm disposed between the input tray and the Paper feeding unit, and configured to be switchable disposed between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path; and a guiding arm, the guiding arm is disposed in the feeding path through a pivot shaft, and includes a guiding portion, the pivot shaft is located upstream of the separation roller, and the guiding portion is swingable disposed in a seam space formed by the Paper feeding unit and the separation roller; and wherein a distance from the axle of the separation roller to the guiding portion is greater than the wheel diameter of the separation roller, and the vertical distance between the paper to be fed and the guiding portion is greater than the vertical distance between the paper to be fed and the separation roller.

A medium transport apparatus includes: a feed unit feeds a medium to a transport direction; a first detection unit disposed upstream of the feed unit, and detects movement of the fed medium; a second detection unit disposed downstream of the first detection unit and detects an inclination of the medium; and a control unit detects the inclination of the medium based on a signal of the second detection unit and stop transfer of the medium when the inclination exceeds a threshold value, and the plurality of the threshold values have a relationship such that when a medium length in the transport direction is a second length being shorter than a first length, a relatively higher value is produced than in a case in which the medium length is the first length, and the control unit selects a threshold value based on a detection value of the first detection unit.

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

A paper sheet separation device includes a separation roller coming into contact with paper sheets, a feed roller rotating with respect to the separation roller to convey the paper sheets separately one by one, and a pair of guide members having guide faces coming into sliding contact with a front end of the paper sheets and being provided on both sides in an axial direction of the separation roller. A friction coefficient of the guide face is smaller than a friction coefficient of a peripheral face of the separation roller. The guide face is provided protruding outward of the separation roller from the peripheral face of the separation roller in a radial direction of the separation roller. The guide face is supported to be able to move inward in the radial direction of the separation roller at a contact point between the separation roller and the feed roller.

Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

A toy device for dispensing stackable or rollable materials and related methods are described. The device has a housing arranged to contain a stack or roll of material and having a dispensing aperture. A manually actuated drive mechanism is provided by which a user can rotate a drive wheel of the drive mechanism. The drive wheel contacts and when rotated engages a portion of the material and to drive it through the dispensing aperture. A release mechanism is provided that can be moved to allow the material to be driven through the aperture. The drive mechanism can be actuated independently from the release mechanism.

An example of the claim method includes, in response to detecting a rejected media unit, directing a media feed path towards a reject area. The method includes depositing the rejected media unit into the reject area. The reject area is defined by a cassette surface on a body of the ribbon cassette. The ribbon cassette is unable to be removed from the media processing device until the rejected media unit is removed from the cassette surface.

A pickup mechanism includes a paper feeding channel, a pickup roller assembly disposed in the paper feeding channel and projecting beyond a top of the paper feeding channel, a paper tray disposed to an upstream of the pickup roller assembly, and a guiding swing arm assembly. The guiding swing arm assembly includes two guiding swing arms mounted adjacent to and spaced from two opposite sides of the pickup roller assembly. Each guiding swing arm includes a pivoting shaft, a stopping block, and an extending arm connected between the pivoting shaft and the stopping block. The two stopping blocks of the two guiding swing arms are disposed between the pickup roller assembly and the paper tray for blocking paper. An axial direction of the pivoting shaft of each guiding swing arm is deviated from a center axis direction of the pickup roller assembly.
