It is an object of the present invention to provide method for receiving sheets for a sheet supplying apparatus. The method includes converting an up and down motion of a tray to a rotational motion of a rotary member by a movement conversion mechanism, converting the rotational motion of the rotary member around a rotational axis to a linear motion of a cylindrical member parallel to the rotational axis by the rotary member and a cam and slider mechanism, and elastically pressing an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray by a compression spring.

A feeding system for carton blanks is disclosed, comprising a pivotable linkage, a gripper head connected to the pivotable linkage at a first rotational axis. The feeding system comprises a magazine configured to store a plurality of stacked carton blanks in a stacking direction. The carton blanks are confined in a cassette being dimensioned so that the carton blanks are confined to extend between proximal and distal internal surfaces of the cassette along a cassette direction which is perpendicular to the stacking direction and the first rotational axis. The proximal internal surface is arranged to align proximal edges of the carton blanks in a proximal alignment plane being perpendicular to the cassette direction, the proximal alignment plane extending between the gripper head and said first rotational axis. The first rotational joint is positioned in relation to the magazine such that there is a separation distance between the proximal alignment plane and the first rotational axis.

An example system includes a pressure plate actuating portion. The pressure plate actuating portion includes a cam gear coupled to a cam arm and a pressure plate arranged to be driven by the cam arm as the cam arm rotates with the cam gear through a pick-up cycle, the pressure plate being biased in a first direction toward the cam arm with a pressure plate spring. The example system also includes a pressure plate release control portion, the pressure plate release control portion being arranged to transfer potential energy from the pressure plate spring in a gradual manner.

Separation strips in a dam aid in the separation of adjacent sheets of media being fed from a stack of sheets so that only one sheet is fed to a process station and, more particularly, to separating the uppermost or top sheet of a stack of sheets from the next adjacent sheet during feeding of the top sheet from the stack of sheets of media. When a lift plate is present that adjusts the height of the media stack, rotation of the separation strips to maintain a constant separation angle improves media feed reliability. Curvature of the separation strips may also maintain the separation angle as the lift plate raises the position of the top media sheet.

The present invention discloses gripper bar locking apparatus and sheet processing device. In particular, the present invention discloses a gripper bar locking apparatus, which is configured to lock and adjust a position of a gripper bar, comprising: a supporting plate having a distal end and a proximal end; a lever portion, a distal end of which is pivotally mounted on the proximal end of the supporting plate; a cartridge movably mounted on a proximal end of the lever portion and provided with a gripper bar abutment; and an adjusting means provided on the cartridge and configured to adjust a position of the cartridge with respect to the lever portion. Further, the present invention relates to the sheet processing device including the gripper bar. By using the gripper bar locking apparatus, the adjustment of the position of the gripper bar is facilitated.

A device for overlapping sheets includes at least one blower box and a supply table. Multiple sheets are guided into a region of the blower box consecutively, in the same transport direction, and are arranged at a distance from one another on the supply table. A blower nozzle is arranged in the blower box, on the side thereof facing the supply table. A blowing direction of the blower nozzle is oriented and parallel to the supply table and against the transport direction of the sheets. The supply table is arranged below the blower box and multiple blower nozzles are arranged in the blower box, one after the other, in the transport direction of the sheets, on the side thereof facing the supply table. A respective blowing direction of the blower nozzles is oriented in parallel to the supply table, and against the transport direction of the sheets.

A sheet feeding apparatus includes a sheet stacker to stack at least one sheet; a sheet feed roller disposed at one side of the sheet stacker and to feed a sheet fed from the sheet stacker; a multi-feed prevention roller disposed to face the sheet feed roller and to prevent multi-feed of the sheet fed from the sheet stacker; a magnetic torque limiter disposed coaxially with the multi-feed prevention roller; a hall sensor disposed at one side of the magnetic torque limiter and to detect rotation of the magnetic torque limiter; and a controller configured to rotate the sheet feed roller in a state in which the sheet feed roller and the multi-feed prevention roller are in contact with each other without a sheet and to identify a lifetime of the multi-feed prevention roller by using a signal output from the hall sensor.

A sheet stacking device including a position regulating member movable in a first direction toward a sheet edge and in a second direction away from the sheet edge, in order to regulate position of the sheet. The position regulating member includes a lock member movable between an engage position and a release position and a lock releaser that moves the lock member from the engage position to the release position. The lock releaser includes a lever member, an upper portion of the lever member including an operation portion, a pivot support that allows the lever member to tilt in the first direction and the second direction, and release mechanisms that move the lock member to the release position when the operation portion is tilted in either direction. Both the release mechanisms are provided on one side of the pivot support in the first direction or the second direction.

An escrow unit has an escrow wheel and a movable-continuous belt. The escrow wheel rotates about an axis. The movable-continuous belt is wrapped partially around the escrow wheel forming an open gap between the belt and escrow wheel. The open gap allows the belt to transport a document through the open gap and to store the document by holding the document between the belt and the escrow wheel.

A medium conveyance device includes a first loading base that has a first loading surface formed thereon and is movably supported on a main body, a second loading base that has a second loading surface formed thereon and is movably supported on the first loading base so that the second loading surface is positioned next to with the first loading surface and so that the second loading surface overlaps with the first loading surface, a mechanism that converts motion of the first loading base into motion of the second loading base so that the second loading base is arranged in a position corresponding to a position in which the first loading base is arranged, and an elastic member that is elastically deformed when the second loading base is not arranged in a position corresponding to a position in which the first loading base is arranged.
