Bag Filling Holding Elements with Shaping Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for filling bags with products often result in large or heavy bags slipping off holding elements, leading to potential damage and inefficiency, as they rely on clamping which can harm the bag material.
Innovation Solution
The use of holding elements with shaping elements that plastically deform the bag material to secure it, allowing for a form-fit retention without clamping, thereby preventing slipping and material damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping is used to hold the bag on holding elements, then the bag can be retained securely, but the bag material is damaged
Solution Approach 1:
The holding elements are designed with specific geometric parameters (curved surfaces, rounded edges, optimized contact areas) that change the interaction parameters between the holding element and bag material. This allows the bag material to be deformed plastically to conform to the holding element shape without requiring high clamping forces, thus securing the bag while minimizing damage
Solution Approach 2:
The holding elements feature curved and rounded surfaces instead of sharp edges or flat clamping surfaces. This curvature allows the bag material to wrap around and conform to the holding element shape, creating a form-fit retention that secures the bag without concentrating stress at sharp points that would cause damage
2Ease of operation
If holding elements are introduced into the bag, then the bag can be held open, but large or heavy bags slip off the holding elements
Solution Approach 1:
The holding elements are designed with optimized geometric parameters including surface area, curvature radius, and contact length that enable them to accommodate and securely hold large or heavy bags. The parameters are tuned to distribute the load and create sufficient friction and form-fit retention
Solution Approach 2:
The curved surfaces of the holding elements allow the bag walls to conform and wrap around them, creating a secure form-fit retention. This curvature prevents heavy bags from slipping off by distributing the holding force along the curved contact surface rather than at a single point

Function Achieved in This Case
This solution ensures secure retention of the bag on the holding elements, preventing slipping and damage, while allowing the bag to be opened and filled efficiently without clamping, thus enhancing the handling and filling process.
Implementation Method 1
at least some holding elements each have at least one shaping element against which a wall of the bag bears in each case such that the material of the wall is preferably plastically deformed in order to hold the wall on the respective holding element via the respective shaping element

AI summary
A device and a method for filling bags with products, wherein the bags have an opening via which the bags are each filled with at least one product, wherein walls of the bag are spaced apart from one another in the region of the opening in order to introduce the at least one product into the bag via the opening, and wherein, after the walls are spaced apart and before the at least one product is supplied, holding elements are introduced into the bag through the opening in order to hold the open bag in the region of the opening. At least some holding elements have at least one shaping element against which a wall of the bag bears in each case such that the material of the wall is preferably plastically deformed in order to hold the wall on the respective holding element via the respective shaping element.
