Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveying devices and presses face issues with clogging and unproductive downtimes due to fluctuations in the amount of pressing material, leading to operational disturbances and safety hazards, especially when processing bulky materials like cardboard packaging.
Innovation Solution
A conveying device with a movable conveying arm and a conveying head that limits the amount of material transported, allowing excess material to fall back into the feeding space, preventing overloading and clogging, and utilizing a rotor roller system for further compaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flat conveying shield is used to feed pressing material, then the material can be conveyed from the feeding space, but clogging occurs when the downstream conveying device or press cannot process the material quickly enough
Solution Approach 1:
The conveying shield is made pivotable around a horizontal axis instead of being fixed, allowing it to dynamically adjust its position. When clogging is detected or material accumulates excessively, the shield can pivot to reverse the working direction, enabling manual removal of jammed material and preventing operational interruptions.
Solution Approach 2:
The conveying shield operates with periodic reversal of its working direction. During normal operation, it conveys material forward; when material accumulation becomes excessive or clogging occurs, the direction reverses to allow material removal, creating a cyclic operation that maintains system reliability.
2Adaptability or versatility
If manual feeding is used to introduce pressing material, then flexibility is maintained, but large fluctuations in material amount occur leading to overloading and safety hazards
Solution Approach 1:
The system incorporates feedback through the pivotable conveying shield that responds to material accumulation levels. When material builds up to excessive amounts in the feeding space, the increased weight and resistance trigger or facilitate pivoting of the shield, which reverses the conveying direction and removes excess material, preventing overloading and safety hazards.
Solution Approach 2:
The conveying shield automatically responds to material accumulation through its pivotable design. The system self-regulates by pivoting when material reaches critical levels, eliminating the need for external monitoring or intervention to prevent overloading, thus maintaining safety while preserving manual feeding flexibility.
3Quantity of substance
If excess pressing material accumulates in the feeding space, then manual removal is required, but this increases labor demand and creates unproductive downtimes
Solution Approach 1:
The pivotable conveying shield enables dynamic response to material accumulation. When excess material builds up, the shield can pivot to reverse the conveying direction, automatically initiating material removal without requiring manual intervention or causing production downtime, thus maintaining continuous operation.
Solution Approach 2:
The system employs periodic reversal of the conveying shield's working direction. During normal operation, material is conveyed forward; when accumulation reaches a threshold, the direction reverses to remove excess material, creating a rhythmic operation that prevents downtime and maintains productivity.
4Reliability
If the conveying shield reverses working direction to remove excess material, then material can be cleared, but this requires skilled observation and intervention
Solution Approach 1:
The pivotable conveying shield is designed to automatically respond to material accumulation through its mechanical feedback mechanism. The system self-regulates by pivoting when material reaches critical levels, eliminating the need for skilled operators to continuously monitor and manually trigger reversals, thus simplifying operation while maintaining reliable material clearance.
Solution Approach 2:
The system incorporates inherent feedback through the pivotable shield mechanism that responds to material weight and accumulation. This automatic feedback loop triggers direction reversal when needed, removing the requirement for skilled human observation and intervention, thereby simplifying operation while ensuring reliable material clearance.

AI summary
A conveying device and/or press having a feed device connected upstream and having a feeding space for material to be pressed. A feeding space bottom is cylindrically bent and rises in a transfer region upstream of the conveying device. A conveying apparatus which can be pivoted to and fro by means of a drive is provided in the feeding space, a pivot axis of the conveying device coinciding with a virtual center axis of the cylindrical shape. At least one rotatably driven rotor roller is arranged adjacent to the transfer region to further convey or press the material. The conveying apparatus is a conveyor arm with a conveyor head, and in order to convey the limited quantities of the material to be pressed from a position in a lower region of the bottom upwards to the transfer region, the conveyor head can be moved to and fro over the bottom.
