Blanked Refuse Winding Apparatus for Label Paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blanked refuse winding apparatuses for continuous label paper face issues with securing sufficient strength for blanked refuse, leading to breakage due to varying tension and contraction, especially when the shape is non-rectangular, and struggle with maintaining a stable winding speed and preventing vibration and twisting.
Innovation Solution
A blanked refuse winding apparatus with a releasing roller, a refuse winding shaft, a moving mechanism, detectors, and a calculator to adjust the roll diameter and apply constant tension, along with a refuse pressing roller and guide belts to stabilize the winding process, ensuring smooth release and raising of blanked refuse without breaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the blanked refuse is released from backing paper and wound around the refuse winding shaft, then the winding process can be completed, but the blanked refuse may break due to insufficient strength and varying tension
Solution Approach 1:
The refuse winding shaft is made movable in the width direction of the blanked refuse, allowing dynamic adjustment of the winding position. This enables the system to adapt to tension variations and contraction changes during winding, preventing breakage while maintaining high winding speed
Solution Approach 2:
A guide belt is introduced as an intermediary element to carry the blanked refuse from the releasing roller to the refuse winding shaft. The guide belt provides stable support and controlled transport, reducing direct tension on the blanked refuse and preventing breakage during the winding process
2Ease of operation
If the refuse winding shaft rotates at constant torque, then the winding can proceed smoothly, but the tension on the blanked refuse varies due to roll diameter changes
Solution Approach 1:
The system uses detectors to monitor the roll diameter of the wound blanked refuse and provides feedback control. The refuse winding shaft position is automatically adjusted based on detected roll diameter changes, maintaining constant tension despite variations in winding conditions
Solution Approach 2:
The system changes the position parameter of the refuse winding shaft in the width direction based on detected roll diameter. This parameter adjustment compensates for tension variations caused by changing roll diameter, maintaining stable winding conditions
3Shape
If the blanked refuse is carried in a prescribed shape, then the label structure is maintained, but contraction in the width direction causes ruffling and load concentration
Solution Approach 1:
The guide belt acts as an intermediary that supports the blanked refuse during transport, distributing loads evenly and preventing ruffling. The guide belt maintains the prescribed shape while preventing contraction-induced instability through continuous support
4Stability of the object's composition
If the carrying path from releasing roller to refuse winding shaft is made longer, then the blanked refuse has more space to settle, but the refuse path becomes too long causing more contraction and breakage risk
Solution Approach 1:
The guide belt provides a controlled intermediary path that is sufficiently long for the blanked refuse to settle and stabilize, yet maintains proper tension and support to prevent excessive contraction and breakage. The guide belt mediates between the need for settling space and the risk of breakage
