This disclosure relates to a media sheet transport apparatus. Specifically, this disclosure relates to a bidirectional print media sheet transport for use in a printing system.
Conventionally, printing systems include media sheet transports which route media sheets such as cut sheet paper from a sheet feeder to one or more marking engines for marking the media sheets with text and/or an image. Subsequent to the image marking engine marking the media sheet, the marked media sheet is routed through a fuser for further fixing of the toner to the media sheet. From the fuser, the marked media sheet may be routed to one or more other marking engines or routed to a finisher module which further processes the marked media sheet and possibly stacks the finished sheets.
To accommodate transportation of media sheets from the sheet feeder to one or more marking engines or other printing apparatuses, a media sheet transportation system is integrated within the printing system. Conventionally this media sheet transportation system includes a series of integrated nip assemblies. The nip assemblies include a top roller and bottom roller, where the media sheet passes between the rollers and one of the rollers is driven by a motor in a single direction. Notably, conventional printing systems include a unidirectional highway configuration to transport media sheets. To accomplish bidirectional media sheet travel within the printing system, multiple media sheet highways are integrated where a first series of nip assemblies provides media sheet travel in a first direction and a second series of nip assemblies provides media sheet travel in a second direction.
This disclosure provides a bidirectional media sheet transport which includes bidirectional nip assemblies to transport a media sheet in two opposite directions.

To facilitate bidirectional travel of a media sheet, nip bottom rollers 44 and 46 are driven by a belt 24 which is driven in a counter clockwise direction or a clockwise direction by the motor 34. In addition to bottom rollers 44 and 46, the nip assemblies include top rollers 20 and 22, where media sheets pass between the top and bottom rollers of the nip assemblies.
To provide proper tensioning of the belt 24 for counter clockwise and clockwise rotation, the transport comprises tensioning arms 26 and 27 which include rollers 28 and 30. The rollers 28 and 30 engage the belt to provide proper tensioning of the belt 24 depending on the direction of rotation. The tensioning arms 26 and 27 are coupled to the motor 34 by a mechanical fastening means at roller 32. Roller 32 engages the belt 24 which drives the nip bottom rollers 44 and 46 to transport a media sheet along the media sheet path/track 18.
In operation, the transport 10 may operate to transport a media sheet from media sheet input/output 12 to media sheet input/output 14 as illustrated in
With reference to
Initially, a media sheet (not shown) is transported from the media sheet input/output 12 to the transport 10 by means of a controllable baffle arrangement. Specifically, the media sheet input/output baffle 40 is in a relatively closed position while the transport media sheet input/output baffle 36 is in a relatively open position. This configuration provides for routing of the media sheet where the bidirectional media sheet transport 10 and media sheet input/output 12 are not mechanically integrated. To control the positions of the input/output baffles 36 and 40, an actuator and spring arrangement may be used.
After the media sheet is fed into the transport 10 along the media sheet path 18, nip rollers 20 and 44 further advance the media sheet wherein bottom roller 44 rotates in a counter clockwise direction by means of the belt 24. As shown in
After the media sheet is driven by nip rollers 20, 44, 22 and 46, the media sheet continues to be driven by the nip assemblies associated with motor 50 until the media sheet is ejected from the transport 10 into the media sheet input/output 14 by means of a baffle interface. Notably, the baffle interface includes a transport media sheet input/output 38 baffle in a relatively closed position and a media sheet input/output baffle 42 in a relatively open position.
With reference to
Initially, a media sheet (not shown) is transported from the media sheet input/output 14 by means of media sheet input/output baffle 42 and transport media sheet input/output baffle 38. Notably, the media sheet input/output baffle 42 is in a relatively closed position and the transport media sheet input/output baffle 38 is in a relatively open position.
From this point the media sheet travels along the media sheet path 18 being driven by the nip rollers associated with motor 50 and 34. Notably, to rotate the bottom drive rollers 46 and 44 in a clockwise direction, the motor 34 rotates clockwise which rotates tension arm 26 to engage roller 30 and the belt 24. The media sheet is driven to the media sheet input/output and ejected from the transport 10 by means of the input/output baffle arrangement which comprises transport media sheet input/output baffle 36 in a relatively closed position and media sheet input/output baffle 40 in a relatively open position.
Notably, the exemplary embodiment illustrated in

The baffle bottom member 62 comprises a baffle bottom member arm 70, a baffle bottom member pivot point 72 and a spring 74 operatively connected to the baffle bottom member arm 70. In operation, one or more actuators (not shown) such as a solenoid, motor, etc., are mechanically attached to springs 68 and 74. The actuator is controlled to exert the necessary forces to open and close baffle top member 60 and baffle bottom member 62.
Regarding the media sheet input/output baffle 40, this baffle assembly comprises hardware which is similar or identical to the transport media sheet input/output baffle 36. The media sheet input/output baffle 40 comprises a baffle top member 80 and a baffle bottom member 82. The baffle top member 80 comprises a baffle top member arm 84, a baffle top member pivot point 86 and a spring 88.
