Paper Sheet Handling Alignment with Dual-Sided Tapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet handling apparatuses align paper sheets by tapping from one side, resulting in a large operation stroke and prolonged alignment time.
Innovation Solution
A paper sheet handling apparatus with a conveyance unit, accumulation and storage unit, and control unit that aligns paper sheets from both sides using movable alignment units to reduce alignment time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If paper sheets are aligned by tapping from one side using a single alignment unit, then the structure is simple, but the operation stroke becomes large and alignment time increases
Solution Approach 1:
The alignment mechanism is segmented into multiple independent alignment units (first alignment unit and second alignment unit) positioned at different locations. Each unit independently taps the paper sheets from its respective side, allowing parallel alignment operations that reduce total alignment time while maintaining structural simplicity through modular design
Solution Approach 2:
The alignment action is extended from one dimension (single-sided tapping) to two dimensions (dual-sided tapping). By positioning alignment units at both ends of the paper sheet in the width direction, the system achieves simultaneous multi-point alignment, effectively reducing the operation stroke required for each individual alignment unit while completing alignment more quickly
2Device complexity
If paper sheets are aligned by tapping from one side, then the device complexity is low, but the operation stroke becomes large
Solution Approach 1:
The alignment function is segmented into multiple units operating simultaneously from different sides. Each alignment unit only needs to move a short distance to tap the paper sheet at its respective location, rather than requiring a long operation stroke to cover the entire width from a single position
Solution Approach 2:
The alignment approach transitions from a single-dimensional linear sweep across the paper width to a multi-dimensional configuration where alignment units are distributed at both ends. This allows each unit to operate with a reduced stroke length while collectively achieving full-width alignment through parallel action

AI summary
A paper sheet handling apparatus includes an accumulation and storage unit that accumulates and stores paper sheets conveyed by the conveyance unit while aligning the paper sheets, the accumulation and storage unit having an accumulation unit that accumulates the paper sheets so that a first direction which is one of a vertical width direction and a horizontal width direction and a second direction which is the other of the vertical width direction and the horizontal width direction are oriented in predetermined directions, a first alignment unit that is movable between a first retracted position spaced apart from the paper sheets and a first alignment position in contact with one end edge of the paper sheets positioned in the first direction; and a second alignment unit that is movable between a second retracted position spaced apart from the paper sheets and a second alignment position in contact with other end edge of the paper sheets positioned in the first direction, with a control unit that causes the paper sheets to be aligned in the first direction by causing the first alignment unit and the second alignment unit to move from the first retracted position and the second retracted position to the first alignment position and the second alignment position and tap the paper sheets accumulated in the accumulation unit from both sides of the first direction.
