Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

A device for detecting the presence of abnormalities in a reel includes an image capturing module for capturing images of the reel including at least one camera, a displacer for displacing the reel in a field of view of the at least one camera, an analyzer for analyzing the images captured by the at least one camera and detecting the presence of abnormalities. The image capturing module including an upper capturer and lower capturer, the upper capturer fixed on a movable support arranged for being movable with respect to lower capturer, the upper capturer and/or the lower capturer including at least one three dimension camera arranged for providing a three dimension image of the reel.

A medium-feeding apparatus includes a movement detector configured to output information on movement of a medium in a first direction parallel to a feeding direction and in a second direction intersecting the feeding direction. A control unit is configured to perform abnormal feeding processing depending on the movement of the medium in the second direction. In the abnormal feeding processing, the control unit stops feeding of the medium when a first value indicating the movement of the medium in the first direction is within an allowable range and when a second value indicating the movement of the medium in the second direction exceeds a threshold, and continues feeding of the medium when the first value is outside the allowable range.

A mail processing system utilizes a conveyor to shingle or de-shingle mailpieces as they move through the processing system and utilizes belts to move the mailpieces. A first shingling conveyor moves a first mailpiece to overlap with a second mailpiece to create shingled mailpieces. A second shingling conveyor moves a first mailpiece away from a second mailpiece to de-shingle them to create singulated mailpieces. A camera takes images of the mailpieces in the conveyor and image analysis software is used to determine dimensional aspects of the mailpieces that are used to control the belt speeds to move mailpieces with respect to each other. A mail processing system may include a mail processing station that scans addresses, applies postage and/or weighs the mailpieces. Mail may be de-shingled prior to being weighed and then re-shingled for subsequent processing, or mail may be shingled prior to passing through a scale if weighing is not necessary.

A printing system for printing on sheets of media having a non-uniform thickness profile. A user interface is controlled to instruct the operator to load a media tray with a stack of media having a specified pattern of media orientations. A media transport system picks sequential sheets of media from the media tray. A front end supplies sequential image data having orientations in accordance with the specified pattern of media orientations. A printing module sequentially prints the supplied image data on the sheets of media in accordance with the specified pattern of media orientations.

A sheet conveyance apparatus includes a conveyance roller, an abutment member including an abutment surface against which a side edge, in a width direction, of the sheet abuts, and configured to correct a skew of the sheet, an obliquely conveying roller configured to convey the sheet such as the side edge of the sheet is conveyed toward the abutment surface, a sheet side edge detection portion configured to detect a position of the side edge of the sheet, and a control unit configured to control that a conveyance force, in the width direction, by the obliquely conveying roller in response to a detection result of the sheet side edge detection portion becomes smaller than that in an abutment movement.

The present disclosure relates to a method performed by an alignment system for aligning tethers of a drop stitch fabric prior to feeding the drop stitch fabric to a drop stitch fabric processing machine. The alignment system feeds a drop stitch fabric having a first layer and a second layer tethered by drop stitch tethers, wherein the first layer is moving with a first velocity and the second layer is moving with a second velocity. The disclosure also relates to an alignment system in accordance with to the foregoing.

A conveying apparatus includes a conveyor and a conveyed object receptor. The conveyor includes a conveyance surface facing downward and configured to convey a conveyed object having a sheet-like shape. The conveyed object receptor is arranged below the conveyor and configured to receive the conveyed object having fallen from the conveyor.

A printing system includes a printing unit, a determination unit, and a switching unit. The printing unit prints an image on a recording medium. The determination unit compares a prestored reference image and a read image corresponding to a reading result of a printed document in which the image is printed on the recording medium and determines whether a result of the comparison satisfies a predetermined condition. The switching unit switches a discharge destination of the recording medium based on a result of the determination. The switching unit switches a conveyance path of the recording medium based on whether the determination is performed.

A feeding device includes: a supply unit that supplies air into space between plural media loaded to float the media; a feeder that adsorbs the media floated by the supply unit and feeds the media; a separator that supplies air to a second medium disposed immediately below a first medium adsorbed by the feeder to separate the second medium from the first medium; a detector that detects a position of at least one of the first medium and the second medium after air is supplied by the separator; and a modifier that modifies a condition related to a feeding operation of the feeder based a position detected by the detector.
