Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag filling systems experience unwanted mechanical loads and oscillation due to mass inertia during transport, leading to inefficient filling processes and increased complexity and cost in preventing swinging of bag sections at filling stations.
Innovation Solution
A positioning device with transverse positioning elements attached to the filling station frame, which extend below the filling hopper to stabilize the bottom section of the bag, preventing further oscillation and ensuring precise positioning for the filling process.

Engineering Contradiction Analysis
1Speed
If a gripping device transports bag sections in cycles with acceleration and braking, then the bag sections can be moved between stations, but the bottom end of the bag section swings due to mass inertia causing unwanted mechanical loads and positioning errors
Solution Approach 1:
The positioning device applies a counteracting force in advance to prevent the harmful swinging motion caused by mass inertia during braking. The positioning elements are arranged to actively counterbalance the inertial forces before they can cause significant deviation, thereby maintaining stable positioning despite the cyclic acceleration and braking of the gripping device.
Solution Approach 2:
The positioning device acts as an intermediary between the gripping device and the bag section. It absorbs and compensates for the harmful effects of acceleration and braking, providing a stable reference frame for the bag section during transport. The positioning elements serve as mediators that decouple the motion disturbances from the bag section.
2Stability of the object's composition
If cleats are arranged on the conveyor belt to prevent bag section swinging, then positioning stability can be improved, but the system becomes very complex and cost-intensive with larger installation space requirements
Solution Approach 1:
The positioning device is divided into separate positioning elements that are independently attachable to the station frame. Each positioning element can be independently adjusted and positioned, allowing for modular installation and maintenance. This segmentation reduces overall system complexity compared to an integrated cleat system on the conveyor belt.
Solution Approach 2:
Instead of adding complexity in the horizontal transport dimension (cleats on conveyor belt), the solution moves the positioning function to the vertical dimension by attaching positioning elements below the filling hopper. These elements extend downward to engage with the bottom end of the bag section, providing stabilization without interfering with the horizontal conveyor operation.
3Productivity
If the bag section is positioned obliquely under the filling hopper due to swinging, then filling can proceed, but undesired mechanical loads are applied to individual areas of the bag section
Solution Approach 1:
The positioning device performs preliminary positioning of the bag section before the filling process begins. By ensuring the bag section is correctly positioned and stabilized in advance, the device prevents oblique positioning that would lead to concentrated mechanical loads during filling. The positioning elements engage with the bottom end of the bag section to establish proper alignment before material is introduced.
