The sheet loading unit includes a supply mechanism that moves a plurality of stacked sheets in a direction toward a feeding position located at an end of the loading unit, a feeding mechanism that individually feeds sheets to the feeding position, and a control unit controlling a plurality of sensors, which detect whether there is a sheet at the feeding position. The supply mechanism operates based on detection information of the sensors. The control unit monitors a relationship between signal information of the optical sensor and that of another sensor, and if a signal relationship that is not normal as compared to that of normal feeding occurs, the unit retracts the signal information of the optical sensor and uses only the signal information of the other sensor.

    Abstract: A method and apparatus for feeding media sheets in an image production device is disclosed. The method may include applying air downward to a top of a trailing edge of a media sheet located at a top of a media stack that is to be fed to an image production section of the image production device, the applied air causing the top media sheet to separate from the media stack, and feeding the separated top media sheet to the image production section.

  • Patent number: 8235378
    Abstract: A sheet take-out apparatus includes a supplying structure configured to move a plurality of sheets supplied in a stacking state in a stacking direction and supply a sheet at a leading edge thereof in a movement direction to a take-out position, a take-out structure configured to make contact with the sheet supplied to the take-out position and rotate, thereby taking out the sheet in a direction almost orthogonal to the stacking direction, and move the sheet to a conveying route, a suction structure configured to generate an air current to suck the sheet at the leading edge in the movement direction to the take-out position on an upstream side of a position where the take-out structure makes contact with the sheet in the sheet take-out direction by the take-out structure, and a controller configured to control an operation of the suction structure so as to decrease suction force by the suction structure when the sheet at the leading edge in the movement direction is not taken out by the take-out structure.

  • Publication number: 20120098184
    Abstract: This invention provides a system and method for aligning, feeding, trimming, slitting, rotating, cross-slitting and stacking sheets, each containing one or more discrete page images thereon that allows for greater automation of the overall process so that reduced or no manual intervention is required to generate completed book stacks or “blocks” from a stream or stack of printed sheets. Sheets are fed to a first, upstream trimming station to remove margin edges and optionally separate the sheets relative to the discrete page images. The sheets are then rotated 90 degrees and fed to a second, downstream trimming station that trims the right-angle edges and optionally separates the sheets into a final group of full-bleed pages, removing margins and gutter strips. The sheets are fed to a stacking assembly to be tacked in page order and any rejected, defective sheets or stacks are removed from the order.

  • Publication number: 20120056367
    Abstract: This paper feeder brings the uppermost paper sheet of a plurality of stacked paper sheets into contact with paper feed rollers and feeds out the paper sheet in a paper feeding direction by the drive thereof. Side fences for guiding both side edges of the paper sheet on a paper feeding table are provided with a pair of blowing units for blowing air to both side edges of the paper sheet, whose air quantity can be controlled independently of each other. When skewing occurs, the blowing units are controlled to blow a larger quantity of air to the paper side edge having larger friction against a lower paper sheet as compared with the quantity of air to the other paper side edge. In paper feeding, problems such as skewing, multi-feeding and idle feeding can be addressed.

  • Patent number: 8056895
    Abstract: The present invention provides a method and apparatus separating a media combination from a stack of interleaved slip-sheets and printing plates and relates to image recording systems such as, for example, computer-to-plate (CTP) systems. Image recording systems include imaging systems that image an image recordable material in response to imaging information. Image recordable materials can include, for example, printing plates. Image recording systems can include integrated systems that additionally process the image forming materials. Additional processing can include, but is not limited to materials punching, materials bending, exposure to non-imaging radiation, chemical development and materials drying. The present invention relates to a materials handling system that separates a media combination from a media stack that includes image recordable materials. A slip-sheet separates each of the image recordable materials from one another in the media stack.
