Label Dispenser Cradling Roll Without Axle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label dispensing methods are cumbersome, often requiring manual peeling or the use of handheld machines, and often involve structures that disrupt adjacent label rolls when removing or inserting rolls.
Innovation Solution
A label dispenser apparatus with a lower roll retaining member and an upper tape guide assembly that cradles label rolls, allowing for easy dispensing and removal without axles or central structures, featuring a peel shaft and support shaft to separate labels from the film, and optional separator blades for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual peeling or handheld machines are used for label dispensing, then labels can be dispensed, but the process is cumbersome and inefficient
Solution Approach 1:
The label roll is designed to be self-servicing through its hoop configuration that naturally guides the label film through the dispensing mechanism without requiring manual intervention or external machines. The hoop structure allows the label to feed itself through the system as it is dispensed.
Solution Approach 2:
The label roll is segmented into individual labels that can be dispensed one at a time through the hoop mechanism. Each label is separated and fed through the dispensing path independently, allowing for controlled, individual label dispensing rather than handling the entire roll at once.
2Reliability
If axles or central structures are used to retain label rolls, then rolls can be held in place, but removal or insertion of rolls disrupts adjacent label rolls
Solution Approach 1:
The central axle or hub structure is completely removed from the label roll design. Instead, the hoop configuration allows the label film to pass through the center of the roll without requiring any central support structure, enabling independent roll handling without affecting adjacent rolls.
Solution Approach 2:
Each label roll is made independent by eliminating the central axle that would connect multiple rolls. The hoop configuration allows each roll to be a separate, self-contained unit that can be inserted or removed without mechanical interference with neighboring rolls.
3Volume of moving object
If a compact design is used for the label dispenser, then space is saved, but integration with product wrapping stations becomes more difficult
Solution Approach 1:
The hoop configuration and label dispensing mechanism are designed to be universally compatible with different product wrapping station configurations. The same basic hoop structure can accommodate various label roll sizes and types, and can be integrated into different wrapping station designs without requiring custom modifications.
Solution Approach 2:
The label dispensing system is designed with dynamic adaptability, allowing the hoop and label path to adjust to different operational requirements. The mechanism can accommodate varying label sizes, roll diameters, and dispensing speeds while maintaining a compact form factor, enabling integration across different application scenarios.

AI summary
A label dispenser apparatus configured for dispensing labels from a plurality of rolls of a carrier film having labels disposed thereon. The label dispenser apparatus includes a lower roll retaining member and a upper tape guide assembly. The lower roll retaining member includes a front edge, a back edge and a concave surface therebetween. The concave surface being configured to cradle a roll of film having labels disposed thereon. The upper tape guide assembly is spaced apart therefrom and includes a peel shaft, a support shaft and a carrier shaft. The film guide path extends behind and around the peel shaft, between the peel shaft and the support shaft, looping around the support shaft and over the carrier shaft, such that a label is released by the movement around the peel shaft, and the label path proceeds directly over the support shaft and the carrier shaft.
