Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote transport systems face difficulties in efficiently switching and loading batches of banknotes with mismatched orientations into a cashbox without unpiling or misalignment, particularly when transporting multiple banknotes in an upright state.
Innovation Solution
A direction switching and transferring device equipped with a stacker unit that clamps banknotes, rotates them, and transfers them onto a takeout member, allowing for lateral switching of banknotes' attitude by a predetermined angle, enabling simultaneous loading into a cashbox while maintaining the batch intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If banknotes are transported in a stacked manner with mismatched orientation, then the transport capacity is improved, but the difficulty of loading into cashbox increases
Solution Approach 1:
The patent applies dynamics by making the stacker unit rotatable to change its orientation dynamically. The stacker unit can rotate between a first orientation (parallel to transport direction) and a second orientation (orthogonal to transport direction), allowing the system to adapt the orientation of banknotes during transfer to match the cashbox loading requirements while maintaining high transport capacity
Solution Approach 2:
The patent introduces a rotational dimension to the otherwise linear transport system. By adding the ability to rotate the stacker unit around the transport direction axis, the system can switch between different orientations (parallel and orthogonal) without changing the linear transport path, thus solving the orientation mismatch problem while maintaining efficient stacked transport
2Manufacturing precision
If banknotes are switched direction one by one, then the orientation matching is improved, but the time required for loading increases
Solution Approach 1:
The patent merges the orientation switching function with the batch transfer function. Instead of switching orientation for each banknote separately, the stacker unit rotates once to change the orientation of the entire batch of banknotes simultaneously, achieving both precise orientation matching and rapid batch loading
Solution Approach 2:
The system performs preliminary orientation adjustment by rotating the stacker unit to the appropriate orientation before transferring the banknotes to the cashbox. This preliminary action ensures that all banknotes are correctly oriented before loading begins, eliminating the need for time-consuming individual orientation adjustments during the loading process
3Manufacturing precision
If a twisted transport route is used to switch attitude, then the orientation switching is improved, but the installation space and transport speed are worsened
Solution Approach 1:
The patent segments the orientation switching function from the transport path. Instead of twisting the entire transport route, only the stacker unit is made rotatable while the transport path remains straight. This segmentation allows orientation switching without requiring additional installation space or compromising transport speed

AI summary
The present invention includes a stacker unit SU that includes a transport body 500 moving along a transport route 400 while retaining paper sheets in an upright state and stopped at a paper sheet extraction position PP, and clamping means 812 and 803 clamping the paper sheets on the transport body, and that switches the direction of the paper sheets in a process of reciprocatively rotationally moving between an upper limit position and a lower limit position, and an operating mechanism 730 that rotationally moves the stacker unit forward and reversely. The clamping means performs an opening/closing operation to clamp paper sheets when the stacker unit is at the upper limit position, and performs an opening operation to cancel clamping of paper sheets after a time when the stacker unit reaches the lower limit position.
