ROTATABLE-MEMBER-SUPPORTING STRUCTURE, TRANSPORT DEVICE, CHARGING DEVICE, AND IMAGE FORMING APPARATUS
A rotatable-member-supporting structure includes a first rotatable member having a shaft portion, a bearing member by which the shaft portion of the first rotatable member is rotatably supported, a pressing member that presses the bearing member in one direction, and a supporting member by which the bearing member is supported in such a manner as to be retractably movable in the direction in which the pressing member presses the bearing member. A pressing force generated by the pressing member is greatest in a portion of the bearing member that is on a downstream side in a direction of rotation of the first rotatable member with respect to an intersection between the bearing member and a first virtual line extending from a center of rotation of the first rotatable member toward the pressing member in the direction in which the supporting member is retractably movable.
TAPE PROCESSING DEVICE AND TAPE PROCESSING METHOD
A tape processing device includes a sending and processing section that performs a tape process while sending processing tape, a cutting section that is disposed on a downstream side of the sending and processing section in a tape sending direction and cuts the tape-processed processing tape, a discharging section that is disposed on the downstream side of the cutting section in the tape sending direction, feeds the processing tape, and holds the cut processing tape, a sending and interlocking section that interlocks driving of the sending and processing section and driving of the discharging section, and a sensing section that determines presence and absence of the processing tape held in the discharging section.
Laminating apparatus
There is described a laminating apparatus for coupling electrodes of non-rectangular shape with a separating film for the manufacture of electric energy accumulating devices, wherein a pair of laminating rollers has a roller driven by an elastic arrangement loaded with a variable force adjusted by an endless screw conveyor controlled by a brushless motor, during the passage of the electrodes, so as to vary the laminating force according to the width of the electrode laminated instant by instant, in order for the laminating pressure to remain almost constant.
Assembly and process for a press feed mechanism for providing rapid, efficient and tuned hold and release displacement of an upper feed roller relative to a lower roller and between which is communicated a sheet material for subsequent feeding into a press operation
A feed assembly for transferring an uncoiled sheet material to a downstream material forming operation. The assembly includes upper and lower feed rolls between which the sheet material passes, the upper roll being actuated between engaging or disengaging positions relative to an upper surface of the sheet material. At least one continuous force applying component is provided for exerting a hold down force against the upper feed roll and, in combination, a programmable counterbalance component is calibrated to counter the hold down force exerted by the force applying component and in order to cycle the upper roller between the engaged and disengaged positions during advance cycling of the uncoiled material to the downstream forming operation.
PRINTING APPARATUS
A printing apparatus capable of fixing a medium appropriately during printing is provided. The printing apparatus includes a feeding roller, a printing portion configured to make a print on the textile supplied from the feeding roller, and a conveyance portion configured to convey the textile to the printing portion. The conveyance portion includes a pressure roller configured to sandwich the textile and rotate along with conveyance of the textile. The printing apparatus further includes a brake roller disposed between the pressure roller and the feeding roller for producing force acting on the textile against conveyance force for the textile by the conveyance portion to apply tension to the textile between the brake roller and the pressure roller. Tension smaller than tension exerted on the textile between the brake roller and the pressure roller is exerted on the textile between the brake roller and the feeding roller.
DRIVE TRANSMISSION APPARATUS AND IMAGE FORMING APPARATUS
The present disclosure provides a drive transmission apparatus capable of reducing vibration of rotating member. The apparatus includes a shaft, a pin, and a rotating member. The rotating member is engaged with the shaft by the pin and rotates with the shaft. A protruded portion is provided on one of an outer circumferential surface of the shaft and an inner circumferential surface of the rotating member. The rotating member is attached to the shaft with the protruded portion in pressure contact with another one of the outer circumferential surface of the shaft and the inner circumferential surface of the rotating member, so that swinging of the rotating member around the pin is restricted.
SHEET CONVEYING APPARATUS AND SHEET POST-PROCESSING APPARATUS
A sheet conveying apparatus (20) includes a first sheet conveyance passage (3), a second sheet conveyance passage (5), a pair of feed rollers (3r1), a first pair of conveyance rollers (50), and a contact-release mechanism (60). The second sheet conveyance passage (5) branches from a branch section (31) on the first sheet conveyance passage (3). The first pair of conveyance rollers (50) has a first roller (51) and a second roller (52) and conveys a sheet along the first sheet conveyance passage (3). When, in the branch section (31), a sheet is conveyed from upstream with respect to the sheet conveyance direction in the first sheet conveyance passage (3) toward the second sheet conveyance passage (5), the sheet conveying apparatus (20) makes the contact-release mechanism (60) move the second roller (52) away from the first roller (51) and makes the pair of feed rollers (3r1) convey the sheet.
SHEET PROCESSING DEVICE, SHEET LAMINATOR, IMAGE FORMING APPARATUS, AND IMAGE FORMING SYSTEM
A sheet processing device includes a rotator, a first nipper, a conveyor, a second nipper, a detector, a memory, and circuitry. The rotator winds a two-ply sheet around the rotator to generate a winding circumferential difference between two sheets of the two-ply sheet to separate the two sheets. The detector detects an abnormal condition, in which a gap greater than a given interval is not formed between the two sheets around the rotator. The memory stores a detection result as the abnormal condition. The circuitry is to increase a nipping force of the second nipper with the rotator, and increase the nipping force in a present sheet processing to be greater than a previous nipping force of the second nipper in a previous sheet processing, when the memory stores the detection of the abnormal condition in the previous sheet processing, to wind the two sheets around the rotator.
Sheet post-processing apparatus and image forming system
A sheet post-processing apparatus (1) includes a processing tray (5), a sheet discharge port (7), a conveyance rollers pair (4), lower and upper discharge rollers (81), (82) and a discharge tray (9). When the sheet having a folded portion is stacked on the processing tray (5) with the folded portion downward, a controller rotates the lower and upper discharge rollers (81), (82) to advance the folded portion to the sheet discharge port (7), stops the lower discharge roller (81) before the folded portion passes the sheet discharge port (7), rotates the conveyance rollers pair (4) and the upper discharge roller (82) so as to convey the rear half portion to the downstream side until the sheet passes the conveyance rollers pair (4) and to form a deflection on the sheet, rotates the lower and upper conveyance rollers (81), (82) and then to stack the sheet on the processing tray (5).
Device for cutting film-like media
Methods and systems are provided for rewinding and cutting a film-like material. In one example, a method may include adjusting a position of a retractable driven shaft located between a first roller from which the film-like material is unwound and a second roller onto which the film-like material is rewound during the rewinding and cutting operations. The method may further include adjusting a tension applied on the film-like material based on speeds of a first shaft holding the first roller and a second shaft holding the second roller, and a brake force applied onto the first shaft.
