Strip Feeding Apparatus Reel Replacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing strip feeding apparatus for stirrer dispensers in beverage vending machines faces issues with high operation costs and time due to frequent machine stoppages and sheet material waste during reel replacement, as the manual unwinding process often results in reel uncoupling and deformation, leading to hygiene issues and increased intervention times.
Innovation Solution
A strip feeding apparatus with a support frame and a casing that houses the reel, featuring a positioning and handling device with a tilting mechanism to stabilize the reel during replacement, allowing for easy reel swapping and minimizing waste by guiding the strip to the forming and cross-cutting apparatus without manual unwinding, thus preventing reel uncoupling and enabling efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual unwinding and insertion of the strip is performed during reel replacement, then the reel can be replaced, but the reel may uncouple from the hub and fall to the ground causing deformation and hygiene issues
Solution Approach 1:
The patent applies preliminary action by pre-positioning the strip end in the shaping apparatus before the reel is fully mounted on the hub. The strip is fed through the dragging rollers and into the shaping apparatus in advance, so that when the reel is coupled to the hub, the strip is already in place and can be immediately processed without manual intervention during the coupling operation.
Solution Approach 2:
The patent uses an intermediary mechanism in the form of a positioning device that guides and holds the strip end in the correct position during reel replacement. This positioning device acts as a mediator between the reel mounting operation and the strip feeding system, ensuring the strip is properly positioned without requiring manual handling that could cause reel uncoupling.
2Productivity
If the reel is manually unwound and the strip is inserted during replacement, then the reel can be mounted, but machine stoppages increase and intervention time is required
Solution Approach 1:
The positioning device pre-positions the strip end and prepares the feeding path before the reel replacement is complete. This allows the strip to be automatically fed into the shaping apparatus immediately after mounting, eliminating the need for manual unwinding and insertion operations that cause machine stoppages.
Solution Approach 2:
The system enables self-service by automatically feeding the strip from the newly mounted reel through the dragging rollers and into the shaping apparatus without requiring operator intervention. The positioning device and automatic feeding mechanism work together to complete the reel replacement process without manual unwinding or insertion steps.
3Ease of operation
If manual unwinding is performed during reel replacement, then the strip can be inserted, but sheet material waste occurs due to reel uncoupling and deformation
Solution Approach 1:
The positioning device performs preliminary action by pre-positioning the strip end and preparing the feeding path before the reel is fully mounted. This ensures that when the reel is coupled to the hub, the strip is already correctly positioned and can be automatically fed without manual handling that could cause reel uncoupling, deformation, and subsequent material waste.
Solution Approach 2:
The automatic feeding mechanism with positioning device enables self-service by automatically guiding and feeding the strip from the mounted reel through the dragging rollers and into the shaping apparatus. This eliminates manual unwinding and insertion operations that frequently result in reel uncoupling and sheet material waste due to deformation or hygiene issues.

AI summary
In a strip feeding apparatus (11), particularly for a stirrer dispenser (2) in a beverage vending machine (1), a reel (8) coupled to a support (18) to rotate about an unwinding axis (22) is moved from a retracted strip feeding position to an extracted reel loading or changing position via a handling device configured to arrange the unwinding axis (22) horizontally when the reel (8) is arranged in the retracted strip feeding position and tilting downwards and towards a flat reel abutment wall (20) when the support (18) is arranged in the reel loading or changing position.
