Sheet conveying device and recording apparatus

Номер: US20120050438A1
Автор: Itaru Wada
Принадлежит: Canon Inc

A sheet conveying device having a rolled-sheet supporting unit, a conveying unit, a driving unit, a tension applying unit, and a control unit. The rolled-sheet supporting unit supports a continuous sheet rolled up into a roll. The conveying unit conveys the continuous sheet from the rolled-sheet supporting unit as driven by the driving unit. The tension applying unit applies tension to the continuous sheet downstream of the conveying unit in a conveying direction. The control unit controls a driving amount of the driving unit per unit conveyance distance as the conveying unit conveys the continuous sheet. The driving amount is larger in a case where a first tension is applied by the tension applying unit compared to a case in which a second tension, that is larger than the first tension, is applied.

An apparatus is disclosed for reducing feed rate variations when unwinding a web material. The apparatus includes a rotational position and speed determining device for determining the rotational position and speed of the parent roll, a drive system for imparting rotational movement to the parent roll, a device for measuring the radius of the parent roll, and a logic device. The logic device generates an ideal speed reference signal and utilizes calculated and measured data to establish a corrected speed reference signal to make adjustments in the driving speed based upon the corrected speed reference signal to maintain a relatively constant feed rate. By dividing the parent roll into 1, 2, . . . n sectors, the data can be refined to a relatively high degree taking into account high speed data processing capabilities as well as operating system response times to make appropriate driving speed adjustments.

A resilient unit is fed as a continuous web 18 through first and second tensioning rollers to a winding roller The winding roller is driven at a first speed, and one or both of the tensioning rollers is also driven, but at a second speed which is less than the first speed—i.e. slower than that of the winding roller. The difference is speeds causes tension to be applied to the material of the resilient unit which stretches the resilient unit and in turn compresses the resilient elements in their pockets. The result is that the resilient unit becomes compressed in its through thickness direction—the axial direction of the springs—before it is wound into the winding roller. The resilient unit extends in length in a longitudinal direction in which tension is applied. The extension in length is substantially proportional to a reduction in a thickness of the resilient unit. 1.
