A printing system includes: a first printing unit that performs printing on a medium on the basis of first printing data; a first inventing unit that is located downstream from the first printing unit in a transportation direction specific to the medium and performs an inverting operation that is an operation of inverting front and back sides of the medium; a second printing unit that is located downstream from the first inverting unit in the transportation direction and performs printing on the medium on the basis of second printing data; and a control unit that determines whether the first inverting unit needs to perform the inverting operation, on the basis of whether the second printing data indicates a printing page for the front or back side of the medium.

A medium reversing and discharging device includes a discharger that discharges a medium in a paper discharge direction from a discharge outlet, a holder that holds and reverses the medium, and a driver that moves the holder such that when a first plane along a portion of the medium in contact with the discharge outlet does not intersect with a second plane along a portion of the medium held by the holder on a downstream side in the paper discharge direction of the discharge outlet a moving speed at which the holder moves is lower than a discharge speed at which the medium is discharged from the discharge outlet.

Sheet collating device for accumulating sheets from at least one hopper, comprising: a lower transport path and an upper transport path; a switchable guide for directing the sheets from the at least one hopper to the lower or the upper transport path; left and right upper drive shafts connected to a right and a left upper drive pulleys supporting a pair of upper belts, a drive direction of the pair of upper belts being changed dependent on what transport path of the upper and lower transport paths is selected; first and second lower drive shafts connected to a right and a left lower drive pulleys supporting first and second pairs of lower belts; and a first series of right paddles mounted on the first pair of lower belts and a first series of left paddles mounted on the second pair of lower belts for registering a collated set of sheets.

A method and apparatus for depositing discrete elements on a support element. The discrete elements may be separated from each other or joined to form a continuous web. The discrete elements are fed into a pick-up station defined at a rotor which includes circumferentially adjacent pick-up members. Each discrete element is associated with a respective pick-up member having a first orientation with respect to a respective second axis of rotation. Each pick-up member is moved along the rotation direction towards a release position downstream with an at least partially accelerated or decelerated motion. Each pick-up member is rotated about the respective second axis of rotation until it takes, at the release position, a second orientation. Each discrete element is released on a support element at the release position. Each pick-up member is subsequently moved towards the pick-up station with an at least partially decelerated or accelerated motion.

A first transport path is put into a first state capable of transporting a paper sheet when a first portion and a second portion engage with each other, and put into a second state in which the second portion is swingable with respect to the first portion about a first swing axis extending in a direction orthogonal to a first direction and horizontal when engagement between the first portion and the second portion is released. A contact portion comes into contact with the second portion, thereby engaging the second portion with the first portion when a second unit in which the first transport path is in the second state is moved in a second direction opposite to the first direction.

A turning station for metal sheets or metal sheet stacks, having a first support which forms a first support plane for a first side of the metal sheets, and having a second support which forms a second support plane for a second side of the metal sheets. The supports are rotatable about a horizontal rotation axis and provided with a plurality of detents which project beyond longitudinal edges of the metal sheets. The supports are part of a rotary installation with a frame having two end-side rotary bearings on a common rotation axis and a basket which is mounted in the two rotary bearings for motorized rotation about the rotation axis, the basket having end-side linear guides for the two supports. The supports by way of support planes which extend in parallel and are oriented toward one another are held in the basket such that the rotation axis is situated between the two support planes and the two supports in the end-side linear guides are in each case movable in a motorized manner in a movement direction toward and away from the rotation axis. Methods for unpackaging, storing, and turning metal sheet stacks are also provided.

A stacker module includes a lift table, a stacker configured to place sheets that are successively supplied thereto onto the top of a stack forming on the lift table, a controller configured to lower the lift table as the stack grows, a height-adjustable eject table, and an eject mechanism configured to transfer a completed stack from the lift table onto the eject table. The eject mechanism is height-adjustable for transferring stacks onto the eject table in different height positions of the lift table.

The repositioning station (200) allows a continuous shingled stream (120) of overlapping semirigid planar articles (100) to be transported on an incoming conveyor (122) along a transport circuit (204) onto an outgoing conveyor (302) so as to form a stack that can be carried away upon the outgoing conveyor (302). The repositioning station (200) includes a lateral deviation assembly (210) and may also include a final positioning assembly (212). The transport circuit (204) within the lateral deviation assembly (210) follows a generally ellipsoidal deviation path to veer the shingled stream (120) and also to pivot the articles (100) therein about a curvilinear axis (206) from a facedown position to an upright position. The outgoing conveyor (302) can carry the cartons (100) in a direction that is parallel to that of the incoming conveyor (122).

A sheet post-processing apparatus includes a sheet introducing unit, a first sheet discharge unit, a second sheet discharge unit, a sheet processing unit, a sheet conveyance unit, and a control unit. The first and the second sheet discharge unit are configured to be able to discharge a sheet to an outside. The sheet conveyance unit includes a sheet conveyance path arranged between the first sheet discharge unit and the second sheet discharge unit. The control unit controls the sheet conveyance unit to convey the sheet along the sheet conveyance path toward the first sheet discharge unit to a predetermined position at which the sheet is not discharged from the first sheet discharge unit to the outside, then convey the sheet along the sheet conveyance path in an opposite direction toward the second sheet discharge unit, and discharge the sheet from the second sheet discharge unit.

An objective of the present disclosure is to prevent paper sheets from being folded or damaged when the paper sheets are stacked. A paper sheet stacking mechanism (banknote stacking mechanism 50) includes stacking wheels 52, rotary rollers 54, a transport mechanism 70 configured to insert a paper sheet between vanes 52b of the stacking wheels, and a guide (center guide 55) having a guide surface 551 configured to guide the paper sheet. The guide surface has a curved shape having a diameter about a rotary shaft, and the diameter gradually increases from an upstream side toward a downstream side in a rotation direction of the stacking wheels.
