Lid Feed Guide Layout for Stable Sealer Format Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feeding devices for can sealers often experience issues with lid alignment and stability, leading to potential malfunctions and inefficiencies, particularly during format changes when different lid sizes are used.
Innovation Solution
A feeding device with a lid guide that ensures the lid is moved exclusively parallel to a guide plane, eliminating the need for ramps and reducing the likelihood of lid misalignment or jumping out of the guides. This design includes a hold-down device to restrict upward movement and a de-stacking device with a replaceable supporting element for efficient format changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a ramp is used to guide the lid from a different level to the guide plane, then the lid can be transported between different elevations, but the lid may jump out of the guides due to misalignment
Solution Approach 1:
The guide system is segmented into multiple guide elements (guide pins, guide surfaces) that work together to constrain the lid at different locations along its path, preventing jumping out while maintaining reliable alignment throughout the transport process
Solution Approach 2:
A hold-down device acts as an intermediary element that applies controlled pressure to the lid during transport, ensuring the lid remains firmly engaged with the guide plane and preventing it from jumping out of the guides
2Reliability
If the feeding device is designed for a specific lid format, then it provides precise alignment and stable operation, but it requires time-consuming format changes when switching to different lid sizes
Solution Approach 1:
The guide elements and hold-down device are designed to be adjustable rather than fixed, allowing their positions and configurations to be dynamically changed to accommodate different lid formats while maintaining precise alignment and stable operation during each format's use
Solution Approach 2:
The feeding device allows for quick adjustment of key parameters such as guide element positions, hold-down force, and component spacing to match different lid dimensions, enabling fast format changes without compromising operational reliability
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
The solution provides a reliable and efficient lid transport system, ensuring consistent lid alignment and reducing the risk of malfunctions, while also simplifying format changes and reducing downtime.
Implementation Method 1
The lid guide is shaped and arranged at the lid feed in such a way that the lid can be moved in the lid guide exclusively parallel to the guide plane
Implementation Method 2
a hold-down device which is arranged at (in particular above) the lid guide in such a way that a movability of the lid in a spatial direction (in particular upwards) can be restricted
Implementation Method 3
The de-stacking screw 10′ segregates and separates the lids 101′ from the stack 111′ with the aid of a spiral-shaped groove 11′
Implementation Method 4
The lids 101′ are conveyed downwards by gravity in the direction of the de-stacking screw 10′

AI summary
A feeding device for feeding a lid to a sealer includes a lid guide for guiding the lid along a guide plane to the sealer, a lid feed for introducing a lid into the lid guide and a movement device arranged at the lid guide. The movement device movably arranged in such a way that the lid can be moved along the guide plane by the movement device.
