Paper Sheet Wrapping Apparatus with Movable Band Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet processing apparatuses are unable to adjust the band-winding location for paper sheets, limiting their adaptability to different bill types and requiring a fixed apparatus size.
Innovation Solution
A paper sheet processing apparatus with a wrapping device that includes a clamp mechanism to curve the paper sheet bundle and a band winding device capable of winding the band at any position, adjusted by a hand assembly with a motor-driven mechanism to accommodate various bill types without increasing the apparatus size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the band winding position is fixed, then the apparatus structure is simple, but the adaptability to different bill types is poor
Solution Approach 1:
The band winding device is made movable along the stacked bills in the stacking direction, allowing dynamic adjustment of the winding position. The device can be positioned at different locations by moving it along the stack, enabling adaptation to various bill types and winding position requirements without changing the overall apparatus structure.
2Adaptability or versatility
If the band winding device position is fixed, then the apparatus size is compact, but the band-winding location cannot be varied
Solution Approach 1:
The band winding device is designed to move along the stacked bills while maintaining a compact overall apparatus structure. The movement capability allows the device to reach different winding positions on the stack without requiring a larger apparatus footprint, thus achieving location variability within a compact design.
Solution Approach 2:
The band winding device serves multiple functions: it can wind bands at different positions on the stack, accommodate different bill types, and maintain compact apparatus size. This multi-functionality is achieved through the movable design that allows positioning flexibility within the existing apparatus volume.
3Adaptability or versatility
If the apparatus is designed for fixed band winding, then the structure is simple, but it cannot meet different country's bill requirements
Solution Approach 1:
The band winding device can be dynamically positioned at different locations on the stacked bills to comply with various country-specific bill requirements. This dynamic positioning capability allows the apparatus to adapt to different standards without requiring complex adjustment mechanisms, as the movement along the stack provides the necessary flexibility.

AI summary
According to an embodiment, a paper sheet processing apparatus includes a stacking device which stacks paper sheets and a wrapping device which wraps a stacked paper sheet bundle by winding a band thereon. The wrapping device includes a band winding device which winds the band on the stacked paper sheet bundle and tightens it, a hand assembly (96) which grasps the stacked paper sheet bundle by holding an end thereof, a hand assembly drive mechanism (98) which draws the bundle to an arbitrary position by reciprocating the hand assembly in a direction perpendicular to the bundle stacking direction, detectors (118a, 118b, 118c) which detect a plurality of drawn-in positions of the hand assembly, and a control unit which stops the hand assembly at an arbitrary drawn-in position detected by the detectors and adjusts a band winding position on the bundle.
