SHEET SUPPLYING APPARATUS AND PRINTING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18756279 titled 'SHEET SUPPLYING APPARATUS AND PRINTING APPARATUS

Simplified Explanation:

The patent application describes a sheet supply apparatus that can wind a sheet tightly. It includes a driving unit to rotate a roll holding the sheet in different directions, a sensor to detect the leading end of the sheet, and a contact body to press the roll's outer surface.

• The driving unit can rotate the roll in two directions for feeding the sheet.
• The sensor detects the leading end of the sheet.
• The contact body presses the outer surface of the roll.
• The driving unit rotates the roll in the opposite direction until the sensor detects the leading end of the sheet.

Key Features and Innovation:

• Dual-direction rotation capability for feeding the sheet.
• Sensor for detecting the leading end of the sheet.
• Contact body for pressing the roll's outer surface.

Potential Applications:

This technology can be used in industries that require precise winding of sheets, such as printing, packaging, and manufacturing.

Problems Solved:

This technology addresses the issue of ensuring tight winding of sheets without any slack or misalignment.

Benefits:

• Improved efficiency in sheet winding processes.
• Enhanced quality of wound sheets.
• Reduced material wastage.

Commercial Applications:

Potential commercial applications include sheet processing equipment manufacturers, printing companies, packaging companies, and industrial automation companies.

Prior Art:

Readers can explore prior patents related to sheet winding apparatus and sensors in the field of industrial automation.

Frequently Updated Research:

Stay updated on advancements in sheet winding technology, sensor technology, and industrial automation for potential improvements in this apparatus.

Questions about Sheet Supplying Apparatus:

1. What are the key components of the sheet supplying apparatus? 2. How does the sensor detect the leading end of the sheet?

Original Abstract Submitted

A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.
