A device for reducing rotation of an article during singulation of a stack of articles is disclosed. The device may include a torsion element, a rotatable member configured to rotate about an elongated axis of the torsion element between a first position and a second position, and a revolving member coupled to the rotatable member. An outer surface of the revolving member contacts a drive belt in the first position and an article in the second position. The torsion element exerts torque on the rotatable member when it moves from the first position towards the second position. The torque causes the outer surface of the revolving member to apply a frictional force to the article, thereby minimizing rotation of the article. Systems and methods of singulating articles are also disclosed.

A continuous body folding device includes a conveying part having a moving surface that moves while suctioning and holding a first region of a continuous body, the conveying part conveying the continuous body in the longitudinal direction thereof; a first folding reference part in which a first endless belt, which moves in a first circulatory pathway along a first virtual plane including the moving surface, moves along a first reference segment adjacent to a virtual line of the continuous body in the same direction at the same speed as the moving surface; and first guiding members that are disposed along the first reference segment, contact a second region of the continuous body, and fold the continuous body along the virtual line and move the second region toward the first region so that the angle formed by the first and second regions becomes smaller as the continuous body is conveyed downstream.

A conveying unit 2including conveyor belts 7, a stopper 3positioning a sheet S at a folding position P on a conveying path 2, a knife-type folding unit 4, an anti-bounce roller unit 16having rollers 25a, 25b, and a motor 22 are provided. The rollers can be moved back and forth. A roller rotational speed monitoring unit 31 and a roller position setting unit 32 operatively connected to the motor are further provided. In setting mode, the rollers are moved from an upstream or a downstream of a tail end of the sheet positioned at the folding position P toward the tail end at a constant speed and stopped when the rotational speed of the rollers changes.

A device for reducing rotation of an article during singulation of a stack of articles is disclosed. The device may include a torsion element, a rotatable member configured to rotate about an elongated axis of the torsion element between a first position and a second position, and a revolving member coupled to the rotatable member. An outer surface of the revolving member contacts a drive belt in the first position and an article in the second position. The torsion element exerts torque on the rotatable member when it moves from the first position towards the second position. The torque causes the outer surface of the revolving member to apply a frictional force to the article, thereby minimizing rotation of the article. Systems and methods of singulating articles are also disclosed.

A transfer unit includes first and second rollers, a roller switching mechanism, and upstream-side and downstream-side guides. The second roller is arranged downstream of the first roller in the conveyance direction of the recording medium. The roller switching mechanism selectively arranges the first or second roller at a reference position to form a transfer nip. The upstream-side and downstream-side guides are respectively arranged upstream and downstream of the transfer nip in the conveyance direction of the recording member. When the first roller moves to the reference position by the roller switching mechanism, the second roller moves to a first retracted position behind the downstream-side guide, and when the second roller moves to the reference position by the roller switching mechanism, the first roller moves to a second retracted position behind the upstream-side guide.

A diverter conveyor includes a frame supporting an upper conveyor that has an upstream end and a downstream end and that is configured to carry sheets in a first, downstream, direction. A plurality of nip rollers are mounted on the frame upstream of the upstream end of the upper conveyor and are spaced from the upstream end of the upper conveyor by a gap. The nip rollers feed the sheets along a main path to the upstream end of the upper conveyor. A rejection conveyor is supported by the frame and has a portion beneath the gap and extends away from the upper conveyor at an acute angle. A plurality of paddles are mounted at the first gap, and an actuator is operably connected to the paddles and configured to shift the paddles from a first position out of the main path to a second position in the main path.

A device for transporting notes of value comprises a first idler pulley mounted in the device and at least a second idler pulley mounted in the device, as well as an endless belt running around the idler pulleys, and a freely rotatable guide roller mounted in the device and having at least one connecting area for reception in a receiving opening of the device. The axis of rotation of the guide roller has in a first receiving position of the connecting area in the receiving opening a first orthogonal distance to a plane in which the axes of rotation of the idler pulleys run. The axis of rotation of the guide roller has in a second receiving position of the connecting area in the receiving opening a second orthogonal distance to the plane.

A paper sheet transportation mechanism includes: transportation portions between which a paper sheet is sandwiched so as to transport the paper sheet; and a transportation guide that protrudes in a direction of the paper sheet sandwiched by the transportation portions such that the paper sheet is deformed into a wave shape in a cross section perpendicular to a transportation direction of the paper sheet, and that extends in the transportation direction.

A conveyor configured to transport sheets along a transport path from an input end to a discharge end includes a main frame, an upper conveyor deck supported by the main frame and having a plurality of belts and a lower conveyor deck supported by the main frame and having a plurality of wheels. The transport path is defined by the contact surfaces of the plurality of belts in the first contact region and the contact surfaces of the plurality of wheels in the second contact region, and the conveyor is configured such that the sheets make direct contact with the contact surfaces of the plurality of belts and make direct contact with the contact surfaces of the plurality of wheels when the sheets move along the transport path. The wheels are shiftable in the third direction relative to the belts and relative to the main frame.
