METHOD FOR CONTROLLING A WEB IN A PRINTING APPARATUS
A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step. The ready-to-print mode includes the step of: operating the transport assembly to prevent a deformation of the print area of the web in the transport path, while maintaining the web in the ready-to-print mode. The web is maintained ready to print while preventing a deformation of the print area of the web in the transport path.
SHEET CONVEYANCE DEVICE AND IMAGE FORMING APPARATUS
A transmission gear is movable in an axial direction between a first position separated from an output gear and a second position coupled to the output gear in a state where the transmission gear engages with an input gear. The input gear is configured to: by rotating in a first direction by receiving driving force from a drive source, move the transmission gear from the first position to the second position and transmit driving force in the first direction to the output gear via the transmission gear; and by rotating in a second direction, move the transmission gear from the second position to the first position and cancel transmission of driving force to the output gear. The transmission gear is configured to, when the output gear rotates in a state where the transmission gear is located at the first position, not be coupled to the output gear.
Image Forming Apparatus Provided with Transmission Mechanism for Transmitting Drive Force to Reconveying Roller
An image forming apparatus includes: a reconveying unit including a reconveying roller; and a second transmission mechanism. The second transmission mechanism transmits a drive force to the reconveying roller and includes: an input gear; an output gear; an intermediate gear including first and second gears; and first and second swinging gears. The first toothless part of the first gear and the second toothless part of the second gear are provided at such a position that, when the intermediate gear is rotated by a drive force transmitted from the input gear through the second swinging gear while the second swinging gear meshes with the second toothed part of the second gear and the output gear meshes with the first toothed part of the first gear, the first toothless part reaches a position confronting the output gear and then the second toothless part reaches a position confronting the second swinging gear.
Auto-adjusting paper separation mechanism
An auto-adjusting separation mechanism, comprising: a bracket with at least one side arm, a sensor module arranged on the side arm, a rotary shaft arranged at the front end of the bracket; a separation roller set pivotally arranged on the rotary shaft, a sensor wheel arranged to couple with the sensor module, and a torque limiter arranged at the front end of the bracket; wherein, by monitoring the rotation of the sensor wheel with the sensor module, the separating force of the separation roller set is adjustable via a microcontrollers which is capable to adjust the transmission gear set.
Sheet conveying device, image reading device incorporating the sheet conveying device, image forming apparatus incorporating the sheet conveying device, and image forming system incorporating the sheet conveying device
A sheet conveying device includes conveyance passage forming bodies to define a sheet conveyance passage, a nip forming body to form a conveying nip region in the sheet conveyance passage, and a flexible plate body having a support portion to be attached to another body and having a downstream-side end portion as a free end in a sheet conveying direction. The support portion of the flexible plate body is located on an upstream side in the sheet conveying direction with respect to the conveying nip region. The free end being located on a downstream side in the sheet conveying direction with respect to the conveying nip region.
SHEET STORAGE DEVICE AND IMAGE FORMING SYSTEM THEREWITH
A sheet storage device includes a housing, a sheet stacking tray, a shaft, a suspension mechanism, a driving device, and a drive transmission portion. The suspension mechanism includes a plurality of winding pulleys and a plurality of wires. The drive transmission portion includes a plurality of driving gears and a plurality of driven gears. The plurality of winding pulleys permit the engagement positions of the plurality of driven gears with respect to the plurality of driving gears to be changed in the circumferential direction of the shaft. The drive transmission portion changes the respective engagement positions of the plurality of driven gears and thereby changes the respective relative positions of the fixing portions of the plurality of winding pulleys in the rotation direction. This permits adjustment of the respective unwound lengths of the plurality of wires.
Sheet conveying device, image forming apparatus including the same, and sheet conveying method
A sheet conveyance device, an image forming apparatus, and a sheet conveying method that convey a sheet in a predetermined sheet conveyance direction make a surface moving speed of a driven roller higher than a surface moving speed of a drive roller when a rotational driving force from the drive roller is transmitted to the driven roller, and by a one-way clutch that is provided at any place in a drive transmission path from the drive roller to the driven roller, restrict relative rotation of the driven roller in a first rotation direction, which is the sheet conveyance direction, with respect to the drive roller while allowing relative rotation of the driven roller in a second rotation direction, which is a direction opposite to the first rotation direction, with respect to the drive roller.
No-Feed-Roll Corrugated Board or Paperboard Sheet Feeder Retrofit Apparatus and Method
A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.
