  • Patent number: 10384890
    Abstract: A paper feeding device of an embodiment includes a paper feed tray, a blower, and a flow regulating member. A paper bundle in which a plurality of sheets of paper are stacked can be placed on the paper feed tray. The blower is positioned next to the paper bundle placed on the paper feed tray. The blower can generate airflow. The flow regulating member is positioned above the paper bundle placed on the paper feed tray. The airflow from the blower causes the flow regulating member to generate a negative pressure between the flow regulating member and the uppermost sheet of paper of the paper bundle.

A floating preventing member which regulates an upward movement of an uppermost sheet floated by air is provided so as to be lifted and lowered between a tail end regulating plate regulating the position of the sheet above a tray and an adsorbing and conveying portion which conveys the uppermost sheet floated by the air blowing from a downstream air blowing portion. The adsorbing and conveying portion is moved to a predetermined regulating position higher than the height position of the uppermost sheet and lower than the feeding surface of the adsorbing and conveying portion before the sheet is floated, which suppresses the movement of the sheet toward the tail end side caused by the curling of the sheet due to the air.

  • Publication number: 20130026696
    Abstract: A sheet feeding apparatus and an image forming apparatus are provided which can reduce the variability of overlapped portions when feeding sheets in an overlapping manner. When sheets are adsorbed to an adsorption conveyance belt, a suction shutter is switched from a block position to block a negative pressure to an adsorption position to adsorb the sheets by the negative pressure. When the sheets conveyed in an overlapping manner reaches a predetermined number and the next sheet is adsorbed, the timing to switch the suction shutter to the adsorption position is delayed compared to the timing at which a preceding sheet adsorbed in advance and a subsequent sheet overlap.

    Abstract: A sheet-supplying device has a sheet-accommodating tray, a raising/lowering unit, a first position sensor, a second position sensor, a controlling unit. The raising/lowering unit raises and lowers the sheet-accommodating tray substantially. The first position sensor detects a first position indicating a position in the stacked direction of one end portion of a topmost sheet stacked in the sheet-accommodating tray. The second position sensor detects a second position indicating a position in the stacked direction of another end portion of the topmost sheet. The controlling unit controls the raising/lowering unit to raise or lower the sheet-accommodating tray based on both the first position detected by the first position sensor and the second position detected by the second position sensor so that one end of the topmost sheet in the stacked status is positioned at a prescribed position in the stacked direction.

    Abstract: According to one embodiment, a separation and extraction apparatus includes an extraction unit, separation unit, air supply mechanism, detector, and controller. The extraction unit extracts and conveys one or more paper sheets from a stack of paper sheets. The separation unit separates one paper sheet from the other paper sheet(s) of the one or more paper sheets. The air supply mechanism supplies air toward a side surface of the stack. The detector detects a bundle state of the stack, which is related to a contact state between the paper sheets. The controller sets an extraction condition depending on the bundle state, which includes drive conditions for the extraction unit, separation unit, and air supply mechanism.

    Abstract: A sheet handling apparatus is provided that includes a take-out member to take out a sheet from a take-out position by rotating the sheet in a state in which negative pressure is applied to the sheet and the sheet is adsorbed to the take-out member. A conveyor portion receives and conveys the taken out sheet by the take-out member and a control portion controls the take-out member such that, when the sheet at the take-out position is being adsorbed to the take-out member, the take-out member is rotated at a circumferential speed that is slower than a conveying speed of the sheet at the conveyor portion. In addition, when the sheet adsorbed to the take-out member is being transferred to the conveyor portion, the take-out member is rotated at a circumferential speed that is the same as a conveying speed of the conveyor portion at that time.

  • Patent number: 8152160
    Abstract: A tier sheet dispensing apparatus for a conveyor system stores a stack of tier sheets and sequentially dispenses the tier sheets, one at a time, onto the top of a two-dimensionally arrayed layer of objects that is being conveyed on a conveyor system. The tier sheet dispensing apparatus has a curved surface that supports the stack of tier sheets. The curved surface bends the stack of tier sheets in a convex curve that facilitates the removal of a single sheet from the top of the stack. The apparatus also has a lift mechanism that moves vertically over the stack of tier sheets to selectively attach to the top tier sheet in the stack and raise the top tier sheet from the stack. The lift mechanism also moves transversely relative to the stack of tier sheets to position the attached tier sheet over the conveyor for placement of the tier sheet on the layer of objects conveyed by the conveyor.

    Abstract: A sheet feeding apparatus may include a sheet storage unit, an air blowing unit, a suction conveyance unit, and a conveyance guide. A sheet in the sheet storage unit blown by the air blowing unit may be conveyed to the conveyance guide by the suction conveyance unit. The conveyance guide has a guide surface and inclined portions arranged upstream in the sheet conveyance direction, formed therein from a sheet conveyance center to ends in a sheet width direction perpendicular to the sheet conveyance direction. The inclined portions are inclined from the upstream side towards the downstream in the sheet conveyance direction. As a distance in which an inclined portion resides away from the suction conveyance unit increases, the inclined portion becomes positioned more upstream in the sheet conveyance direction.

  • Patent number: 8100397
    Abstract: A timed feeder for feeding corrugated boards to nip rolls of a box finishing machine. An indexing drive mechanism, driven by a computer-controlled servo motor, activates a feed member and has a feed phase when it drives the board to the nip rolls, and a dwell phase when the feed member is away from the feed path and the output shaft of the indexing mechanism is at zero velocity. During the feed phase, the output shaft of the indexing mechanism accelerates the feed member and the board beyond the nip roll velocity and then decelerates them to the nip roll velocity at the point where the board enters the nip rolls. During the dwell phase the input shaft is either accelerated or decelerated to change the duration of the cycle.
