Drawer Module Biasing Guide for Stable Paper Sheet Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper sheet handling apparatuses face challenges in managing gaps between drawable drawer modules and cross conveyance units due to component dimensional variations, leading to potential damage and conveyance issues, especially when transitioning between half-locked and locked states.
Innovation Solution
Incorporating a biasing guide at the end of the cross conveyor to bias the drawer module in the cross direction, along with a retracting mechanism for the comb tooth guide, to manage gaps and prevent damage during module housing and conveyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a gap is provided between the drawer module and cross conveyor to prevent damage, then component safety is improved, but paper sheet conveyance reliability deteriorates due to potential misalignment
Solution Approach 1:
The comb tooth guide is designed to be movable rather than fixed, allowing it to dynamically adjust its position. When the drawer module is pulled out, the comb tooth guide moves to close the gap for reliable conveyance. When the drawer module is housed, the comb tooth guide retracts to prevent contact damage. This dynamic adjustment resolves the contradiction between maintaining gap safety and ensuring conveyance reliability.
Solution Approach 2:
The system performs preliminary actions by moving the comb tooth guide to the appropriate position before the drawer module reaches its operational state. The comb tooth guide advances to close the gap before conveyance begins, and retracts before the drawer module is fully housed, preventing contact damage in advance. This preliminary positioning resolves the contradiction proactively.
2Stability of the object's composition
If the comb tooth guide is fixed to maintain positioning, then positioning stability is improved, but contact damage occurs during drawer module housing
Solution Approach 1:
The comb tooth guide transitions from a fixed structure to a movable one, enabling it to adapt its position based on the drawer module's state. During conveyance, it maintains stable positioning to ensure accuracy. During housing, it moves to prevent contact damage. This dynamic capability resolves the contradiction between stability and damage prevention.
Solution Approach 2:
The position parameter of the comb tooth guide is changed dynamically based on operational requirements. When conveyance is needed, the guide is positioned to maintain stability. When the drawer module is housed, the guide's position parameter changes to retract and avoid contact. This parameter adjustment resolves the contradiction between stable positioning and contact damage prevention.
3Object-affected harmful factors
If the comb tooth guide retracts to prevent contact, then damage prevention is improved, but conveyance positioning accuracy deteriorates
Solution Approach 1:
The comb tooth guide dynamically adjusts its position based on the operational phase. During conveyance, it maintains an extended position to ensure positioning accuracy. During housing, it retracts to prevent contact damage. This dynamic positioning resolves the contradiction between damage prevention and positioning accuracy by applying the appropriate configuration at the appropriate time.
Solution Approach 2:
The comb tooth guide performs preliminary positioning actions before conveyance begins, ensuring accuracy is established in advance. It also performs preliminary retraction before housing occurs to prevent damage. These preliminary actions ensure that when the guide is extended for conveyance, positioning accuracy is maintained, and when retracted for housing, damage is prevented.
