Print Media Stacking Layout for Compact Batch Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses that discharge and stack printed media face challenges in downsizing while effectively sorting media every predetermined number, as known techniques often require moving the stacking portion obliquely, leading to increased apparatus size.
Innovation Solution
The apparatus incorporates a stacking portion that moves orthogonally to the conveyance direction, allowing for sorting by shifting between multiple positions, with a control system that extends and contracts the stacking area as needed, reducing the overall footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stacking portion is moved obliquely to the conveyance direction to sort print media, then sorting function is improved, but the apparatus size increases
Solution Approach 1:
The stacking portion moves in the conveyance direction (longitudinal direction) rather than obliquely, changing the dimension of movement from diagonal to linear. This allows the stacking portion to be positioned at different locations along the conveyance path, enabling sorting functionality while maintaining a compact footprint in the lateral direction.
Solution Approach 2:
The stacking portion is made movable along the conveyance direction and can be positioned dynamically at different locations. The control unit controls the stacking portion to move to a first position for stacking and to a second position for sorting, enabling the apparatus to adapt its configuration based on operational needs without increasing overall apparatus size.
2Quantity of substance
If the stacking portion is extended to secure adequate stacking area, then stacking capacity is improved, but the apparatus footprint increases
Solution Approach 1:
The stacking portion is designed to be extendable along the conveyance direction. The control unit controls the stacking portion to extend to a first position to secure adequate stacking area and to contract to a second position to minimize the apparatus footprint. This dynamic extension allows the system to provide sufficient stacking capacity only when needed.
Solution Approach 2:
The stacking portion is segmented into movable components that can be extended and retracted independently. This segmentation allows the stacking area to be expanded along the conveyance direction without permanently increasing the apparatus footprint, as the segments can be retracted when not in use.

AI summary
There is provided a technique that can suppress upsizing of an apparatus while sorting print media every predetermined number of print media on a stacking portion. To do so, a reciprocating member (433) that reciprocates while being regulated in an X direction orthogonal to a Y direction by a first supporting member (434) is provided, and a second stacking portion (42) extendable in the Y direction relative to the first supporting member (434) is moved in the X direction by action of the reciprocating member (433).
