Ticket Dispensing Apparatus Tension Detection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing apparatuses for receipts or tickets from a continuous strip face issues in coordinating the intermittent advancement of the strip with tensioning, leading to irregular cuts, entanglement, incorrect printing, and failure to dispense subsequent tickets due to simultaneous strip tensioning and advancement.
Innovation Solution
A dispensing apparatus with driven supply means, sensor means to detect strip tensioning, and electronic control means to interrupt strip advancement when tensioning is detected, ensuring the strip is only cut when tensioned by the user, preventing simultaneous advancement during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driven supply means continues to advance the strip during user tensioning, then the strip can be fed continuously, but the cut becomes irregular and the strip may become entangled
Solution Approach 1:
The control means preemptively stops the driven supply means upon detecting user tensioning (via sensor means), preventing the harmful simultaneous advancement that would cause irregular cuts and entanglement. This preliminary anti-action eliminates the conflict between continuous feeding and precise cutting.
Solution Approach 2:
The system dynamically adjusts the operation of the driven supply means based on real-time detection of strip tensioning. The supply means transitions from an active continuous advancement state to a stopped state when cutting is detected, allowing precise stationary blade cutting, then resumes afterward. This dynamic control resolves the contradiction between continuous feeding and cut precision.

AI summary
An apparatus and a method for distributing printed slips or tickets are disclosed that are obtained from a continuous strip of material, in which the strip is cut by a stationary blade when the user tensions the strip by pulling an end thereof; a driven dragging roller that makes the strip advance in an intermittent manner, is interrupted if a sensor detects that the strip is tensioned to be cut.
