Paper Sheet Payout Device Sliding Separation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet storage and payout devices face instability in separating paper sheets from the wrapping peripheral region of the tape due to large changes in the angle of the separation member with respect to the tape, leading to uneven separation and potential jams.
Innovation Solution
A paper sheet storage and payout device with a sliding portion that tracks the amount of tape wrapped around the second take-up drum using a guide roller, maintaining a consistent angle and distance for the separation member, ensuring stable and smooth separation of paper sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the separation member is enabled to oscillate to track the change in tape wrapping amount, then the separation member can follow the payout starting position, but the angle change with respect to the wrapping peripheral region becomes large, causing unstable separation
Solution Approach 1:
The invention transitions from a static separation member to a dynamic sliding mechanism. The sliding portion moves along the circumferential direction of the take-up drum, dynamically adjusting the separation member's position to track the payout starting position while maintaining a constant angle relative to the wrapping peripheral region, thus resolving the contradiction between adaptability and stability
Solution Approach 2:
The sliding portion acts as an intermediary between the separation member and the take-up drum. It mediates the relationship by absorbing the angular variation through its own movement, allowing the separation member to maintain a fixed angle while its position is adjusted to follow the payout starting position, thereby ensuring stable separation
2Device complexity
If the separation member is held fixed, then the structure is simple, but the payout starting position changes with tape wrapping amount, causing poor separation performance
Solution Approach 1:
The invention introduces a dynamic sliding portion that can move along the take-up drum's circumference. This dynamic element allows the separation mechanism to adapt to changing tape wrapping amounts without requiring complex adjustment mechanisms, maintaining relatively simple structure while improving separation reliability
Solution Approach 2:
The sliding portion automatically adjusts its position based on the tape wrapping amount through the interaction with the take-up drum. The mechanism self-regulates to maintain optimal separation conditions without requiring external control systems or complex actuation mechanisms

AI summary
A paper sheet storage and payout device, which, by winding and unwinding tape between a first take-up drum on which the tape is wound from one end, and a second take-up drum on which the tape is wound from the other end, with paper sheets placed thereupon, stores and pays out paper sheets. A separation mechanism is provided on the payout side of the tape from the second take-up drum, and during payout separates the paper sheets from the wrapping peripheral region of the tape wrapped around the second take-up drum. This separation mechanism is provided with a separation member which separates paper sheets from the wrapping peripheral region, and a sliding portion which holds the separation member, and which slides so as to track the amount of tape wrapped around the second take-up drum by bring into contact with the wrapping peripheral region a guide roller.
