Movable Sheet Guide Mechanism for Cost-Effective Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sheet conveying devices face challenges in cost-effectively stacking sheets of different sizes due to the complexity and number of components required for guiding sheets onto a stacking surface.
Innovation Solution
A sheet conveying device with a movable member that includes a first surface inclined at a first angle and a second surface inclined at a smaller angle, both supported to swing parallel to the stacking surface, allowing for efficient guidance and stacking of sheets of varying sizes without increasing the number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate first guide member and second guide member are used to guide sheets of different sizes, then the sheets can be orderly stacked on the stacking surface, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent combines the first guide member and second guide member into a single integrated movable member. This movable member has a first surface corresponding to the first guide member and a second surface corresponding to the second guide member. By merging two separate guide members into one, the patent reduces the number of components while maintaining the ability to guide both large and small sheets accurately for orderly stacking.
Solution Approach 2:
The movable member serves multiple functions: it acts as both the first guide member for large sheets and the second guide member for small sheets. The movable member can swing between a first position where the first surface guides large sheets and a second position where the second surface guides small sheets. This multi-functionality eliminates the need for separate guide members while preserving stacking precision for different sheet sizes.
2Manufacturing precision
If separate first guide member and second guide member are used to guide sheets of different sizes, then the sheets can be orderly stacked on the stacking surface, but the mounting operation becomes troublesome
Solution Approach 1:
The patent combines the first guide member and second guide member into a single integrated movable member. This reduces the number of parts that need to be mounted and assembled, thereby simplifying the mounting operation while maintaining the dual-guidance capability for different sheet sizes.
3Adaptability or versatility
If separate first guide member and second guide member are used, then sheets of different sizes can be guided properly, but the manufacturing cost increases
Solution Approach 1:
The patent merges two separate guide members into one movable member with multiple surfaces. This reduces the total number of components that need to be manufactured, assembled, and inventoried, thereby reducing manufacturing cost while maintaining adaptability to guide both large and small sheets through different surfaces of the same movable member.
Solution Approach 2:
The movable member is designed to perform multiple guiding functions for different sheet sizes. By making one component universal rather than having separate specialized components, the patent reduces manufacturing complexity and cost while preserving the ability to adapt to various sheet dimensions.

AI summary
A sheet conveying device includes: a conveyor; a stacking surface configured to support a sheet to be discharged by a discharge roller, and a movable member, which is provided downstream from the discharge roller in the discharge direction, is supported so as to be swingable on a swinging shaft, wherein the movable member has a first surface and a second surface, wherein the first surface is inclined at a first inclined angle relative to the stacking surface so that the first guide surface is inclined towards the stacking surface, wherein the second surface is inclined at a second inclined angle relative to the stacking surface so that the second surface is inclined towards the stacking surface, and wherein the second inclined angle is smaller than the first inclined angle.
