Abstract:
A sheet medium stacking conveying device and method, wherein the method comprises a medium conveying step, the medium conveying step comprises: moving a stacking mechanism for clamping media from a medium inlet to a medium outlet along a moving path, and discharging the media clamped by the stacking mechanism towards the medium outlet relative to the stacking mechanism in a process of moving the stacking mechanism towards the medium outlet. The stacking mechanism of the conveying device can reciprocally move between a collection position and discharge position of the media under the driving of a driving mechanism, and the media can be discharged under the condition of no additional power source.
Abstract:
For the purpose of delivering a laundry item (10) to an ironer, the laundry item (10) is spread, by opposite corners of a lateral edge (20), by means of spreader clips (18, 19). In this case, deformations, or “ear formation” may occur at the corner regions (12, 13) of the laundry item (10) that are gripped by the spreader clips (18, 19). This “ear formation” is mostly irreversible, and in the long term results in damage to the laundry items (10). The invention creates a method and a device by which the laundry item (10) is delivered to an ironer in a gentle manner. For this purpose, at least one corner region (12, 13) of the laundry item (10) that is gripped by a spreader clip (18, 19) is captured by an imaging means as the laundry item (10) is being spread.
Abstract:
The invention proposes a method and an installation for monitoring and/or controlling at least one handling apparatus for handling a multiplicity of preferably sheet-like products, in particular printed products, each product being assigned a reference (4). The installation comprises a transporting apparatus for transporting the multiplicity of products at a distance apart from one another along a transporting direction to at least one handling apparatus, or past the same, at least one detecting apparatus (1, 1′) at least for picking up references of the products and for communicating messages belonging to the references, and at least one processing unit (3) for processing the messages. In at least one delay device (5), a number of messages relating to references (4) from a plurality of products are combined to form a message group (6) and are communicated to the processing unit (3) via a communications medium (2) once a delay period (9) has elapsed.
Abstract:
A system and method for rotating sheets receiving cut sheets from a source and providing them to a utilization device. The rotator continually engages sheets with at least one drive component throughout the transport and rotation process. The rotator includes a transport mechanism having a plurality of nip roller pairs along the length of a feed table. The nip rollers (nips) can be selectively engaged with, and disengaged from, the driven rollers using discrete actuators. This allows for feed velocity differentials when entering and exiting the rotator feed table, and also for clearance during sheet rotation. A rotator disk assembly is centered on the table between, and comprises a driven rotator disk and an overriding, freely rotating pressure disk. When sheets enter or pass through the rotator section, the pressure disk is raised to provide a clearance for sheets to pass.
Abstract:
This is a media transport apparatus using gripper segments that are connected to conveyor belts. These segments grip the leading edges of paper media and pull the media on a path toward a paper exit. Above the conveyor belts are baffle panels that have at least two panel separations. It is through these separations that the gripper segments move as the endless conveyor belts rotate. The gripper segments are provided with shifting structures that can laterally align the paper sheets. The leading edges of the paper are held between a gripper bar and elastomeric rollers.
Abstract:
An apparatus for recording or reading information on or from a sheet is disclosed. The apparatus includes a holding unit for holding a sheet, a first arm which has one end pivotally fixed to the holding unit, a second arm whose one end or a specific point is pivotally fixed to the first arm, a driving system which can integrally move the other end of the first arm and the other end of the second arm, and can change the interval between the other end of the first arm and the other end of the second arm, a posture regulating mechanism for regulating the posture of the holding unit with respect to the first arm, a sheet supply unit provided with the holding unit, the first arm, the second arm, the driving system, and the posture regulating mechanism, and a recording or reading unit for performing information recording or information reading on a sheet supplied to the sheet supply unit.
Abstract:
This is a paper registration system that allows for a lateral reset while the paper is present in the nip space. By separating the nips, the carriage can move to reset position for the next sheet while the previous sheet is still present in the carriage.In addition, the configuration of the system of the invention is reduced or elimination of reaction forces on the carriage lead screw is provided. The registration embodiments of the present system are especially useful in a high speed marking system.
Abstract:
A device for correcting the lateral position of a printing substrate, preferably a sheet of paper, held by a gripper bar and conveyed in a transporting direction has a linear drive that includes a first primary part and a first secondary part configured as a first carriage and associated with the first primary part, and a second secondary part configured as a second carriage. The first carriage and the second carriage are arranged on the same side of the printing substrate in the lateral direction and—to correct the position of the printing substrate in the lateral direction—are movable relative to each other in the direction of transport. Such a device may be used for transporting printing substrates and for correcting the register position of printing substrates in machines for processing printing substrates, preferably printing presses or machines for the further processing of printed products. The relative movement of the two carriages with respect to each other initiates a lateral movement of the gripper bar without influencing the advancement of the printing substrate.
Abstract:
A method for aligning the leading edge of printing plate (110) to an axially disposed slot (70) in a cylindrical surface (30) of an imaging drum (20) comprising at least one printing plate clamp (90) having a clamp surface (100) disposed parallel to the slot, the method comprising straightening (210) the leading edge against the clamp surface and positioning (220) the leading edge to protrude over the slot by rotating the imaging drum under the plate. The straightening comprises resting (200) the leading edge of the plate on the cylindrical surface of the imaging drum and rotating the imaging drum about its cylindrical axis (60) to contact with the clamp surface a point along the leading edge of the plate and to rotate the plate until its leading edge is in alignment with the clamp surface.
