Vertical Baler Bale Ejection via Bowden Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical balers have complex and space-consuming bale ejection mechanisms with many movable parts, posing safety and mechanical disadvantages.
Innovation Solution
A vertical baler with a simplified bale ejection system using a grabbing arrangement that is vertically displaceable by the ram arrangement, connected to a bale ejector via a flexible Bowden cable, reducing the number of external movable parts and utilizing the same drive mechanism for compacting and ejecting bales.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex bale ejector arrangement with many movable parts is used, then the bale can be ejected from the compactor, but the device complexity increases and safety decreases
Solution Approach 1:
The patent combines the bale ejection function with the existing door opening function by using the door's movement to trigger the ejection mechanism. The door opening action simultaneously activates the grabbing arrangement and initiates the bale ejection process, merging two functions into one coordinated sequence, thereby reducing the number of separate movable parts while maintaining reliable bale ejection
Solution Approach 2:
The door serves multiple functions: it provides access to the compartment for loading waste, and it acts as the triggering mechanism for bale ejection. By making the door multi-functional, the patent eliminates the need for separate ejection controls and reduces the overall complexity of the ejector mechanism while ensuring reliable operation
2Reliability
If many movable parts are placed at the outside of the baler, then the bale ejection can be achieved, but the safety and mechanical reliability deteriorate
Solution Approach 1:
The patent extracts the movable parts of the ejection mechanism from the external environment and relocates them inside the compartment. The grabbing arrangement and its associated movable components are positioned within the compartment, eliminating external movable parts that pose safety risks, while the mechanism remains fully functional for reliable bale ejection
3Object-affected harmful factors
If a simplified ejection system with fewer openings is used, then the risk of waste blocking openings is reduced, but the mechanism for activating the ejector must be simplified
Solution Approach 1:
The door opening action automatically triggers the ejection sequence without requiring additional controls or complex activation mechanisms. The system uses the natural movement of the door as the triggering event, making the mechanism self-activating and eliminating the need for separate ejection buttons, sensors, or control systems, thereby reducing complexity while preventing waste from blocking openings

AI summary
Disclosed herein is a vertical baler for compacting waste such as e.g. cardboard or plastic. The baler comprises: - a compartment for containing the waste to be compacted, the compartment comprising interior sides; - an opening to the compartment; - a ram arrangement comprising a press plate which is configured for moving vertically inside the compartment for compacting the waste; - a door for providing access to the compartment; - a bale ejector; - an activation member exterior to the compartment; - a grabbing arrangement on one or more of the interior sides of the compartment, and - a triggering arrangement.
