The present application relates to rolled good feeding device and method. Material feeding devices and methods are provided for conveying material from material rolls. The material roll may be adjusted in the longitudinal direction during the feeding process by a rectifying frame to aid in maintaining alignment during the unrolling. Tension of the unrolled material may be monitored and unrolling speeds of the feeding device can be adjusted to maintain tension of the material within a range for that material. Aspects also contemplate elements to feed multiple rolled materials simultaneously for subsequent processing in combination as layered materials.

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension-sensor and the edge-sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

A part detecting device of a carrier tape includes a transporting passage, a part detector, and a biasing mechanism that presses the part detector against the carrier tape inside the transporting passage. The carrier tape is transported to the transporting passage. The part detector detects parts stored in storages which are formed on the carrier tape passing through the transporting passage at regular intervals.

A sheet storage apparatus and a printing apparatus include simplified mechanisms for supporting a sheet and for guiding the sheet. A sheet storage device that can store a sheet discharged from a discharge port of a printing apparatus includes multiple flappers provided below the discharge port and arranged in a width direction of the sheet, each flapper being rotatable between a first posture in which the sheet discharged from the discharge port is guided downward in a gravitational direction by using a first surface, and a second posture in which the sheet is supported by using a second surface being different from the first surface; and a connecting unit which connects the plurality of flappers to one another.

A film winding system (1) for a film stretching unit (110) comprises a film entry area (3) through which a film web (2) to be wound can be fed to the film winding system (1). A first winding station (4) is configured in a winding position to wind the film web (2) into a film bale (5). A contact roller (6) and a measuring roller (8) are provided, the contact roller (6) being arranged adjacent to the first winding station (4) in the winding position and being configured to guide the film web (2) to the first winding station (4). The measuring roller (8) is arranged before the contact roller (6) in the movement direction of the film web (2) and is configured to guide the film web (2) to the contact roller (6). A first adjustment device (10) is provided and configured to move the measuring roller (8) relative to the contact roller (6) along a travel path in such a way that a degree of wrapping over which the film web (2) covers the contact roller (6) can be varied.

The present invention relates to a method for processing a covering roll sheet (20) of a package, wherein the covering roll sheet (20) covers a package body (51) in the manner of a lid, comprising the steps of: drawing the covering roll sheet (20) off an endless roll (22), tensioning the covering roll sheet (20), determining an offset between a first marking on the covering roll sheet (20) and a second marking (34) on the package body (51), and stretching the covering roll sheet (20) in a manner dependent on the determined offset between the first marking (33) and the second marking (34).

The present disclosure relates to winding device that includes a controller for determining a winding speed corresponding to a tension profile of a substrate to be wound and for outputting a motor control signal corresponding to the winding speed. The winding device includes an electric motor for rotating a winding core to wind the substrate according to the motor control signal; and a tension sensor that is installed on a conveying roller that transports the substrate wound around the winding core to precisely sense a tension value of the substrate in real time and provide the tension value to the controller. The controller dynamically controls the winding speed of the electric motor by using the tension value.

A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.

A medium placement device configured to have a medium discharged from a discharge unit of a processing device placed therein, and includes: a placement unit including a plurality of placement surfaces, with different angles with respect to a horizontal direction, that are disposed along a discharge direction of the medium, the placement unit being configured to have the medium discharged from the discharge unit placed thereon; and a plurality of restricting members disposed facing the placement unit along the discharge direction, the plurality of restricting members being configured to come into contact with the medium from above. In an initial state in which the medium is not placed, a distance in a gravitational direction between a first end of each of the plurality of restricting members on a placement unit side and one of the plurality of placement surfaces that faces the first end in the gravitational direction is constant.

A tape feeder feeds a component supply tape including a cover tape adhered on a carrier tape accommodating multiple components to a predetermined supply position, and separates the cover tape from the carrier tape in front of the supply position to expose a component on the carrier tape. The tape feeder includes a pair of rotating members configured to separate the cover tape from the carrier tape by pinching and drawing the cover tape; a drum member configured to rotate and wind the cover tape drawn by the pair of rotating members; a driving motor; and a distribution mechanism configured to distribute a rotational driving force from the driving motor to one rotating member of the pair of rotating members and the drum member.
