Sheet Handling Apparatus with Opposing Transport Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet handling apparatuses often experience jamming issues due to sheets with folded or corrugated leading ends, which prevents efficient transportation along the transport path.
Innovation Solution
The apparatus employs a pair of transport members with opposing rotation directions, ensuring both faces of the sheet are in contact with the rotating surfaces, thereby applying a transport force to prevent jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single roller is used to transport sheets, then the device complexity is reduced, but sheets with folded or corrugated leading ends cannot be transported reliably causing jamming
Solution Approach 1:
The transport function is segmented into two independent rollers instead of using a single roller. Each roller independently contacts one face of the sheet, allowing the system to handle sheets with folded or corrugated leading ends by distributing the transport force across both faces of the sheet.
2Force
If both transport members are driven to rotate, then the transport force is increased to prevent jamming, but the energy consumption increases
Solution Approach 1:
Both transport members are pre-configured in a driven rotation state before sheet insertion. This preliminary action ensures that when a sheet is inserted, both faces immediately receive transport force, preventing jamming of sheets with folded or corrugated leading ends without requiring additional energy bursts during operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reliably transports sheets by applying equal force to both faces, preventing jamming and ensuring smooth movement.
Implementation Method 1
the outer peripheral surface of the first transport member and the outer peripheral surface of the second member being configured to convey the sheet along the transport path in response to the first transport member and the second transport member being driven while a first face of the sheet remains in contact with the outer peripheral surface of the first transport member, and a second face of the sheet remains in contact with the outer peripheral surface of the second member

AI summary
A sheet handling apparatus includes: a transport path along which a sheet is transported; a first transport member disposed on one side of the transport path; and a second transport member disposed opposed to the first transport member with the transport path interposed therebetween. The first transport member and the second transport member are driven to rotate. The sheet is transported by the first transport member rotating with an outer peripheral surface thereof being in contact with a first face of the sheet, and by the second transport member rotating in a direction opposite to a rotation direction of the first transport member, with an outer peripheral surface thereof being in contact with a second face of the sheet different from the first face.
