A plate feeding method includes a suction-holding step for causing suction pads to suck and hold an upper surface adjacent an end edge, remote from nip rollers, of each plate, a moving step, while swinging the suction pads about a moving unit, for moving the moving unit toward the nip rollers, thereby inverting a portion adjacent the end edge of each plate P, and subsequently moving the end edge of the plate inverted to a position to be pinched by the nip rollers, a pinching step for causing the nip rollers to pinch the end edge of the plate having been inverted, a releasing step for canceling suction-holding of the plate by the suction pads, a pressing step for pressing the plate with a support roller, and a transporting step for rotating the nip rollers to transport the plate P.

Plate feeding apparatus and plate feeding method

A plate feeding apparatus of this invention includes a storage unitfor storing a plurality of plates P with end edges thereof arranged even by a stopper, a first and a second nip rollersand, a suction devicedisposed at a distal end of an armswingable about a moving unitfor sucking and holding an upper surface adjacent an end edge of each plate, a moving mechanism for moving the moving unitalong the surfaces of the plates, and for swinging the armabout the moving unit, thereby to invert a portion adjacent the end edge of each plate sucked and held by the suction device, and subsequently to move the portion to a position to be pinched by the first nip roller or second nip roller, and a storage unit moving mechanismfor moving the storage unitin directions perpendicular to the axes of the first and second nip rollersand

Plate feeding apparatus

A plate feeding apparatus includes a multi-cassette unit for storing, in a stacked state, a plurality of cassettes storing plates, a loader unit for fetching from each cassette plates to be fed to an image recorder, and a plate feed unit disposed above the multi-cassette unit to be tiltable about a horizontal axis in a state of having a portion thereof vertically overlapping the multi-cassette unit.

An interleaf at the top position of a stack of plates and interleaves stored in a cassette is removed by attaching the interleaf to suction pads mounted to a vertically movable support. When the interleaf in the cassette is moved upwardly to a position opposed to a pair of nip rollers, movable suction pads move horizontally in such a direction as to stretch the interleaf to remove wrinkles in the interleaf. Then, a leading edge portion of the interleaf is held between the pair of nip rollers and removed outwardly.

Interleaf removal apparatus, plate feed apparatus and image recording system

A stack of alternating plates and interleaves are stored in a cassette of a plate feed apparatus. An interleaf is removed from the stack by a plurality of vertically moving suction cups. There are cases where a plate is attached to the back surface of the interleaf during the removal. Lifting up the plurality of suction cups being reciprocated horizontally causes the plate attached to the interleaf to drop off.
