SHEET FEEDING DEVICE AND PRINTING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17984648 titled 'SHEET FEEDING DEVICE AND PRINTING APPARATUS

Simplified Explanation

The patent application describes a sheet feeding device that includes a drive unit, a sensor, and a control unit. The drive unit rotates a roll of wound sheet in both clockwise and counterclockwise directions. The sensor detects the distance between a detecting position and the peripheral surface of the roll, and its output changes accordingly. The control unit determines the amplification factor of the sensor based on acquired data.

  • The drive unit rotates the roll of sheet in both clockwise and counterclockwise directions.
  • The sensor measures the distance between the detecting position and the roll's peripheral surface.
  • The output of the sensor changes according to the detected distance.
  • The control unit determines the amplification factor of the sensor based on acquired data.
  • The acquired data is obtained by changing the amplification factor while the roll is rotated once in the counterclockwise direction.
  • The acquired data includes multiple output values obtained at different rotation angles.

Potential Applications:

  • Sheet feeding devices in various industries such as printing, packaging, and manufacturing.
  • Any application requiring precise control of sheet feeding and detection of distance.

Problems Solved:

  • Ensures accurate detection of the distance between the detecting position and the roll's peripheral surface.
  • Provides a method to determine the appropriate amplification factor for the sensor.
  • Improves the overall performance and reliability of sheet feeding devices.

Benefits:

  • Enhanced accuracy in detecting the distance between the detecting position and the roll's peripheral surface.
  • Improved control of sheet feeding, leading to better quality and efficiency in various processes.
  • Increased reliability and consistency in sheet feeding devices.


Original Abstract Submitted

A sheet feeding device includes a drive unit that rotates a roll of a wound sheet in a first direction and in a second direction, a sensor having an output which changes according to a distance between a detecting position facing a peripheral surface of the roll and the peripheral surface of the roll, and a control unit that determines an amplification factor of the sensor on the basis of data. The data is acquired by changing the amplification factor while the roll is rotated once in the second direction and includes a plurality of the output value acquired at different rotation angles.
