Baling Press Rope Tying Loop Supply Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large baling presses require significant space for loop supply arms and suffer from inefficiencies in bringing rope sections to the knotting area, leading to interference with bale pressing and increased complexity.
Innovation Solution
Suspending the loop supply member on the same side as the knotter and using a rope diverter to urge rope sections between the hook and rope holder towards the bale pressing channel, eliminating the need for additional diverter mechanisms and reducing the loop supply arm's range of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the loop supply arm is positioned at the opposite side of the bale pressing channel to the knotter, then the rope material can be supplied to the knotting area, but the baling press requires significant space and the loop supply arm needs a large range of movement
Solution Approach 1:
The loop supply arm is repositioned from the conventional opposite side to the same side as the knotter. This inversion of the typical arrangement allows the loop supply arm to work in conjunction with the rope diverter mechanism, supplying rope sections to the knotting area without requiring extensive space or large ranges of movement. The rope diverter then guides the rope sections into the knotting area where they are engaged by the knotter.
2Ease of operation
If the loop supply arm is positioned at the opposite side of the bale pressing channel, then rope material can be supplied to the knotting area, but the loop supply arm must be of stiff construction with tight manufacturing tolerances
Solution Approach 1:
The rope diverter acts as an intermediary mechanism between the loop supply arm and the knotting area. Instead of requiring the loop supply arm to directly and precisely deliver rope sections across the bale pressing channel, the rope diverter receives the rope sections from the loop supply arm and guides them into the knotting area. This mediation allows the loop supply arm to have a simpler, more flexible construction with fewer tight tolerance requirements.
3Productivity
If additional rope diverter mechanisms are used to bring rope sections to the knotting area, then the knotting process can be completed, but the device complexity increases
Solution Approach 1:
The rope diverter is designed as a multi-functional component that performs multiple tasks: it receives rope sections from the loop supply arm, guides them into the knotting area, and works in coordination with the knotter to complete the knotting process. By consolidating these functions into a single integrated mechanism rather than using separate diverter mechanisms, the overall device complexity is reduced while maintaining productivity.

AI summary
A baling press has feeding structures for feeding rope materials along opposite first and second sides of the pressing channel (101) and one or more knotters on a first side of the pressing channel (101). The or each knotter (139) includes a knot tier for knotting sections of the rope materials in a knotting area to each other, a cutter and a rope holder for holding rope material cut off from the knotted rope sections. The knotting area is closer to the bale pressing channel than the rope holder. A loop supply member is suspended on the first side of the bale pressing channel and has a hook for catching the rope materials and providing loops thereof at the first side. The rope diverter is arranged for urging sections of the rope materials between the hook and the rope holder towards the bale pressing channel (101) into positions extending through the knotting area.
