Overhead Transport Bag With Segmented Receiving Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhead-conveying transport bags suffer from loaded goods falling laterally during transport and inability to automatically unload without damaging the goods, as they require manual rotation to discharge contents.
Innovation Solution
A transport bag design featuring a basic structure with a receiving device, where the unloading occurs through open front sides, with a retaining device along the transition between structures to prevent lateral falling, and a lifting mechanism to insert a pusher for horizontal unloading, ensuring goods are not damaged during automatic unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the transport bag uses a rigid support wall and open lateral sides for loading, then automatic loading is enabled, but loaded piece goods can drop laterally during transport
Solution Approach 1:
The transport bag is divided into a rigid basic structure and a flexible receiving device. The receiving device with its flexible lateral sides acts as a separate functional element that adapts to contain goods without causing lateral dropping, while the rigid basic structure maintains structural integrity for automatic handling.
Solution Approach 2:
The lateral sides of the receiving device are made from flexible material that can adapt to the goods inside. This flexibility prevents lateral dropping of piece goods while maintaining the open configuration needed for automatic loading, resolving the contradiction between automation and lateral stability.
2Extent of automation
If the transport bag is rotated upside down for unloading, then automatic unloading is achieved, but piece goods can be damaged due to the fall
Solution Approach 1:
Instead of rotating the bag upside down to unload, the invention inverts the approach by keeping the bag in its normal orientation and using a pusher device to horizontally discharge goods through the open front side. This eliminates the harmful rotational movement while maintaining automatic unloading capability.
Solution Approach 2:
A pusher device is introduced as an intermediary mechanism between the goods and the unloading process. The pusher horizontally pushes goods out through the open front side, avoiding direct gravitational falling and associated damage, while enabling automatic unloading operation.
3Extent of automation
If the transport bag has open front sides for unloading, then automatic unloading is enabled, but loaded piece goods can fall out during transport
Solution Approach 1:
The transport bag is segmented into a rigid basic structure with closed sides and a flexible receiving device with open front sides. This segmentation allows the basic structure to maintain containment during transport while the receiving device provides the open front sides necessary for automatic unloading.
Solution Approach 2:
Different parts of the transport bag have different structural qualities: the basic structure has rigid, closed sides for containment during transport, while the receiving device has flexible, open front sides for automatic unloading. This local differentiation resolves the contradiction between containment and unloading accessibility.

AI summary
An overhead-conveying transport bag for automatically unloading a loaded piece good includes a basic structure as well as a separate receiving device, which is arranged adjacent thereto. Unloading of the transport bag is performed through one of the front sides of the basic structure which is open and at least the lateral sides of the receiving device are formed such that the base is liftable into an unloading position of the transport bag, in which the base is lifted into the bottom of the basic structure.
