Pivoting Dispensing Edge for Label Detachment and Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling machines are expensive and inefficient when applying labels to bottles, particularly bottlenecks, due to the need for individual label handling and specialized equipment, which complicates the application process and ergonomics.
Innovation Solution
A dispensing device with a pivoting dispensing arm and head, allowing 2- or 3-dimensional adjustment of the dispensing edge to accommodate various bottle shapes, including bottlenecks, using a carrier strip with a dispensing edge that deflects labels from the tape, and incorporating deflection rollers to prevent label detachment during twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual label handling is used, then labeling precision is improved, but device complexity and cost increase
Solution Approach 1:
The carrier strip is segmented into individual label units that can be independently handled and applied to different bottle locations, enabling precise labeling while maintaining a simpler overall system structure
Solution Approach 2:
The carrier strip acts as an intermediary element that holds multiple labels and facilitates their transfer to bottles, eliminating the need for complex individual label handling mechanisms
2Adaptability or versatility
If specialized tripod equipment is used, then adaptability to different bottle shapes is improved, but ease of operation deteriorates
Solution Approach 1:
The dispensing arm is designed with movable and adjustable components that can dynamically adapt to different bottle shapes and sizes, eliminating the need for complex specialized tripods while maintaining versatility
Solution Approach 2:
The dispensing arm is designed as a universal component that can handle various bottle types (cylindrical, conical, irregular shapes) through its adjustable mechanism, replacing multiple specialized equipment with a single versatile device
3Productivity
If carrier tape is strongly deflected at dispensing edge, then label detachment from carrier tape is improved, but label orientation control deteriorates
Solution Approach 1:
The dispensing edge is designed to deflect the carrier tape in a controlled manner that separates the label detachment function from the orientation control function, allowing both to be optimized independently through multi-dimensional movement control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a flexible, cost-effective, and ergonomic labeling system that can handle diverse bottle shapes, enabling easy application of labels to both belly and neck areas without the need for expensive special tripods, allowing for automatic bonding and improved usability.
Implementation Method 1
The dispensing edge is provided for deflecting the carrier tape in such a way that a respective label currently located on this dispensing edge detaches itself from the carrier tape as a result of this deflection
Implementation Method 2
The dispensing head (12) has a pressure roller (22) for pressing the label onto the bottle
Implementation Method 3
incorporating deflection rollers to prevent label detachment during twisting
