Sheet Conveying Apparatus Separation Piece Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sheet conveying apparatus requires precise alignment and engagement of components during maintenance, particularly the spring and holder, to ensure proper urging force for sheet separation, which can be error-prone and lead to decreased separation efficiency.
Innovation Solution
The apparatus includes a unit assembly with a fit-in member, separating piece, holder, and compression coil springs, allowing for easy replacement and alignment of components, eliminating the need for precise spring engagement with the holder, and ensuring consistent urging force for sheet separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spring and holder are precisely aligned and engaged during maintenance, then the urging force is properly applied for sheet separation, but the maintenance work becomes complex and error-prone
Solution Approach 1:
The holder is divided into a holder body and a separate engagement portion that can be independently positioned. The engagement portion includes positioning protrusions that fit into corresponding recesses on the conveying frame, allowing the holder to be segmented into functional parts that can be assembled with simpler alignment requirements.
Solution Approach 2:
A positioning mechanism acts as an intermediary between the spring and holder, providing fixed reference points through positioning protrusions and recesses. This intermediary structure ensures proper relative positioning without requiring precise manual alignment between the spring and holder during maintenance.
2Stability of the object's composition
If the spring is kept held by the conveying frame during separation piece replacement, then the spring remains in position, but the engagement with the holder becomes difficult and imprecise
Solution Approach 1:
The positioning protrusions and recesses are pre-configured on the conveying frame and holder engagement portions before assembly. This preliminary positioning structure ensures that when the holder is installed, it automatically aligns with the correct position relative to the spring, eliminating the need for precise manual engagement during maintenance.
3Force
If the holder and spring are positioned inappropriately relative to each other, then the urging force is insufficient, but achieving proper positioning requires high accuracy in maintenance work
Solution Approach 1:
The holder's engagement portion with positioning protrusions automatically self-aligns with the conveying frame's positioning recesses during installation. This self-positioning mechanism ensures that the holder and spring are correctly positioned relative to each other without requiring high measurement precision or specialized tools during maintenance work.

Function Achieved in This Case
This configuration simplifies maintenance, reduces the risk of errors, and maintains stable sheet separation accuracy by guiding the sheet effectively through the nip position, even with multiple sheets, enhancing the reliability of the sheet conveying process.
Implementation Method 1
a first urging member provided between the attachment member and the holder for urging the separating piece toward the separating roller

AI summary
A sheet conveying apparatus, including: a base body having a conveyor surface; a separating roller configured to rotate about a first rotation axis parallel to a width direction of the conveyor surface and to convey a sheet downstream in a conveyance direction orthogonal to the width direction; a separating piece opposed to the separating roller and configured to cooperate with the separating roller to separate sheets being conveyed one by one; an attachment member removably attached to the base body at a position at which the attachment member is opposed to the separating roller, so as to form a part of the conveyor surface; a holder holding the separating piece and supported by the attachment member so as to be movable toward and away from the separating roller; and a first urging member provided between the attachment member and the holder for urging the separating piece toward the separating roller.
