TRANSPORT DEVICE AND PRINTING APPARATUS
A transport device includes a transport belt, an abutting unit, a moving mechanism, and a displacement detection unit. The transport belt has an adhesive layer capable of adhering to a medium, and is capable of transporting the medium adhering to the adhesive layer. The abutting unit is capable of abutting against a surface of the adhesive layer. It is assumed that a direction in which the abutting unit is away from the adhesive layer is a first direction and a direction opposite thereto is a second direction. The moving mechanism is capable of moving a position of the abutting unit with respect to the surface in the first direction and the second direction. The displacement detection unit detects a displacement amount of the transport belt in the first direction when the moving mechanism moves the abutting unit in the first direction while the abutting unit abuts against the surface.
TRANSPORT DEVICE AND RECORDING DEVICE
A transport device includes a transporting belt having an endless shape and configured to transport a medium, a first roller including a first circumferential surface brought into contact with the transporting belt, the first roller being a roller around which the transporting belt is wound, a second roller including a second circumferential surface brought into contact with the transporting belt, the second roller being a roller around which the transporting belt is wound, a pressing section including a bearing unit including a contact portion brought into contact with the first circumferential surface, the pressing section being configured to press the first circumferential surface on an inner side of the transporting belt, and a support portion disposed on an inner side of the transporting belt and configured to support the pressing section.
Sheet stacking device and printing apparatus
A sheet stacking device include a guide unit and a blower. The guide unit receives a downstream end of a sheet in a sheet conveyance direction and guides the sheet downstream in the sheet conveyance direction. The blower blows air toward the sheet guided by the guide unit. A region of the blower from which the air is blown is changeable in response to a size of the sheet.
SHEET FEEDING DEVICE AND IMAGE FORMING SYSTEM
A sheet feeding device includes a feeding roller pair, a first guide, a door including a second guide and rotatable between a first direction and a second direction opposite to the first direction through first to third positions, a damping mechanism, and an engaging portion including an elastic member. A first resisting force is set so that moment acting around a shaft by a self-weight of the door is larger than the first resisting force of the damping mechanism when the door is positioned between the second position and the third position. A resultant force of the first resisting force of the damping mechanism and a second resisting force of the elastic portion is set so that the moment acting around the shaft by the self-weight of the door is larger than the resultant force when the door is positioned between the second position and the third position.
Sheet conveying apparatus
A sheet conveying apparatus for conveying a sheet in a conveying direction includes a pair of conveying rollers receiving and conveying a sheet; an endless conveying belt conveying the sheet; a plurality of balls to be rotatable in any direction while nipping the sheet with the conveying surface; a pair of regulating guides disposed on both sides of the conveying belt; a guide moving unit that moves the pair of regulating guides; and a roller moving unit that moves at least one of the pair of conveying rollers to a nip position and a nip release position. Before a rear end of the sheet passes the pair of conveying rollers, the pair of conveying rollers is moved to the nip release position by the roller moving unit, and then, the guide moving unit makes each of the pair of regulating guides reach the guide position from the retracting position.
Sheet feeding apparatus and printing apparatus
A sheet feeding apparatus includes a supporting unit that rotatably supports a roll sheet formed by winding a continuous sheet into a roll shape, a conveying path forming member that is placed in a position spaced apart from the roll sheet supported by the supporting unit, and forms a conveying path of the sheet, and a displacing unit that includes a guide portion capable of being displaced between a guide position and a retracting position set farther from a start position than the guide position. The guide portion is displaced from the retracting position to the guide position when a leading edge of the sheet separated from the roll sheet supported by the supporting unit is positioned between the guide portion in the retracting position and the start position.
Conveying apparatus with conveyance surface facing downward
A conveying apparatus includes a conveyor and a conveyed object receptor. The conveyor includes a conveyance surface facing downward and configured to convey a conveyed object having a sheet-like shape. The conveyed object receptor is arranged below the conveyor and configured to receive the conveyed object having fallen from the conveyor.
Device for feeding sheets
A device is provided for feeding sheets to a sheet-processing machine having at least one processing mechanism. A feeder head is provided for cyclically separating the sheets from a pile of such sheets and has transporting suckers for transporting the sheets to a belt table. The belt table has at least one revolving transport belt which is guided over at least two feed rollers. A first drive is assigned to at least one feed roller and a sheet flap, which is connected to a pivotally mounted shaft, is provided between the transporting suckers and the at least one transport belt. A second drive is assigned to the shaft, for pivoting that shaft. A sheet arrival sensor, which is arranged between the belt table and the processing mechanism, generates first signals representing the arrival of the sheets for a sequence of sheets. A clock generator generates second signals representing the angular position of the at least one processing mechanism, and has a controller, which controls the first drive as a function of the second signals and which controls the second drive as a function of the first and second signals.
Reel editor for pre-print paper, sheet, and box manufacturing systems
Systems for providing efficient manufacturing of paper, sheet, and/or box products of varying size and structure, often with pre-applied print (“pre-print”), are provided herein. Efficient customer ordering/tracking, job aggregation, print imposition, corrugator planning, and tracking and adjustments throughout the manufacturing process are contemplated. A reel editor is configured to edit the roll based on waste and/or errors that occurred during various manufacturing processes (e.g., during printing). A control plan defining what is on each roll of printed web product may be updated after editing. Depending on the configuration, the reel editor may be integrated with various manufacturing components. The reel editor may be configured to determine if there is enough waste on the roll to even making editing worthwhile, such as based on desired quality of the images, customer requirements, different price points, among other possible factors.
SHEET DISPENSING DEVICE
The present invention includes a lift portion lifting and inverting a sheet group including a plurality of stacked sheets and a conveyor portion that moves, along a conveying direction, each sheet transferred from the lift portion, wherein: the lift portion includes frames, a fork portion, an inversion mechanism turning the fork portion to lift and invert the sheet group, and a fork movement mechanism moving the fork portion; the lift portion is equipped with a width direction movement mechanism moving the sheet group in a width direction; and after the sheet group is mounted on the fork portion and before the sheet group is transferred to the conveyor portion, the width direction movement mechanism is controlled on the basis of detection information from a position sensor to center the sheet group within a reference width direction range.
