Bag Transport Holding Unit with Segmented Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag filling devices require complex and space-intensive guide systems for their gripping arms, which are prone to wear and require increased space due to the combination of revolving and longitudinal movements, disrupting continuous operation and increasing space requirements.
Innovation Solution
A simplified holding unit with two separate holders, one mounted on the filling device and the other on a spatially-fixed guide, allowing for independent movement along open trajectories that do not collide with other device parts, enabling continuous operation at constant velocity with reduced space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a gripping arm with combined revolving and longitudinal movement is used to transfer bags, then the filling device can operate continuously, but the guide system becomes complex and space-intensive
Solution Approach 1:
The holding unit is divided into two separate holders (first holder and second holder) that move independently along the same open trajectory. This segmentation simplifies the guide system by eliminating the need for complex combined movement mechanisms, while still enabling continuous bag transfer to the rotating filling device
Solution Approach 2:
The holders move along an open trajectory that includes both radial and circumferential components, effectively using a two-dimensional path instead of a simple linear or circular motion. This dimensional approach allows the holders to synchronize with the rotating filling device without requiring complex guide mechanisms
2Productivity
If a gripping arm with combined revolving and longitudinal movement is used to transfer bags, then the filling device can operate continuously, but the space required at the production location increases
Solution Approach 1:
By separating the holding unit into two independent holders sharing a common trajectory, the overall footprint is reduced compared to a single complex gripping arm mechanism. The shared guide structure eliminates redundant space-consuming components
Solution Approach 2:
Both holders move along the same open trajectory and share a common guide structure, merging the guide systems into a single space-efficient configuration rather than requiring separate guides for each holder
3Productivity
If a gripping arm with combined revolving and longitudinal movement is used to transfer bags, then the filling device can operate continuously, but the guide system becomes susceptible to wear
Solution Approach 1:
The guide system for each holder is simplified to a single-directional open trajectory guide rather than a complex combined movement guide. This reduction in guide complexity directly reduces the number of moving contact points and potential wear locations
Solution Approach 2:
The longitudinal movement function is extracted from the revolving gripping arm mechanism and instead achieved through the independent movement of holders along a fixed open trajectory. This separation eliminates the wear-prone combined movement mechanism

AI summary
A device for transporting and filling bags, preferably open bags, comprising a filling device, which is rotatable about an axis of rotation, having multiple filling openings distributed over the circumference of the filling device, and comprising a feeder, using which an empty bag can be fed to a filling opening, wherein the feeder comprises at least one holding unit for a bag, which is movable normally to the axis of rotation of the filling device, wherein the holding unit has two separate holders, wherein the holders are each movable forward and backward along the same open trajectory, wherein the first holder is mounted so it is movable on the filling device, while the second holder is mounted so it is movable on a spatially-fixed guide.
