Sheet Loading Apparatus Transport Control for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet loading apparatuses face issues with sheet alignment and matching properties during discharge, leading to degraded alignment and potential buckling when subsequent sheets are discharged, requiring improved control mechanisms to ensure satisfactory loading and alignment.
Innovation Solution
The apparatus incorporates a discharge member, a loading member, a tip support member, and a rotation member with a control section that adjusts the transport amount based on the loading amount of sheets, using a detection sensor to determine the optimal transport position and amount to prevent buckling and ensure proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the paper discharge tray has a configuration where discharged sheets return to the upstream side after being discharged, then the sheets can be loaded onto the tray, but the next discharged sheet comes into contact with the returned sheet, causing alignment degradation
Solution Approach 1:
The patent applies preliminary action by having the sheet return to a predetermined position (upstream side) before the next sheet is discharged. The tray configuration and gravity assist the returned sheet to settle at a specific location where it will not interfere with subsequent discharges. This pre-positioning prevents alignment degradation while maintaining easy loading operation.
2Productivity
If the sheet transport amount is not controlled based on loading amount, then the discharge process is simple, but buckling occurs and alignment is degraded when subsequent sheets are discharged
Solution Approach 1:
The patent applies dynamics by making the transport amount adjustable based on the loading amount. The control section dynamically changes the transport amount according to how many sheets are loaded on the tray. When fewer sheets are loaded, a larger transport amount is used to ensure proper positioning. This dynamic adjustment prevents buckling and alignment degradation while maintaining high discharge speed through automated control.
3Manufacturing precision
If the transport amount is increased to prevent buckling, then sheet alignment improves, but the discharge member may not be able to accommodate all sheets properly
Solution Approach 1:
The patent applies parameter changes by adjusting the transport amount parameter based on the loading amount. Instead of using a fixed transport amount or complex mechanical structures, the system changes the transport parameter dynamically. The control section modifies the transport amount to match the number of sheets loaded, which simplifies the discharge member configuration while achieving proper alignment and preventing buckling.

AI summary
A sheet loading apparatus includes a loading member which loads the sheet discharged by the discharge member, a tip support member which abuts against the leading edge of the sheet discharged by the discharge member in the sheet discharge direction, a rotation member which abuts against an upper surface of the sheet discharged to the loading member, and is rotated to transport the sheet to the stopper side, and a control section which controls a transport amount of the sheet through the rotation member based on a loading amount of the sheet loaded on the loading member.
