Multiple Strapping Device With Corkscrew Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bulk-material baling machines are limited in varying the types of tying media applied to different portions of a bale, leading to inefficiencies in the bale ejection process and reduced throughput due to the need for incremental ejection and preset strap placement.
Innovation Solution
A multi-strapping machine with a combination wire and plastic strapping system that allows for an uninterrupted bale ejection cycle, where the number and placement of straps can be strategically adjusted based on material type, using a motor-driven corkscrew system that pre-makes straps and adjusts speed for efficient bale compaction and expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single tying system with preset strap placement is used, then the machine structure remains simple, but the bale ejection speed decreases and throughput is reduced
Solution Approach 1:
The strapping system is divided into multiple independent strapping units (first strapping unit, second strapping unit, etc.), each capable of applying straps at different locations on the bale. This segmentation allows simultaneous or sequential application of multiple straps without requiring incremental ejection pauses, thereby increasing bale ejection speed while maintaining manageable system complexity through modular architecture
Solution Approach 2:
Straps are pre-formed and positioned on the bale during the compaction process before ejection occurs. The corkscrews pre-make and place straps in valleys during bale formation, allowing the ejection process to proceed uninterrupted without stopping to apply straps, thus eliminating the 10-second pause per strap and significantly increasing throughput
2Reliability
If multiple straps are applied per bale with incremental ejection, then bale security is improved, but the time required for full ejection increases
Solution Approach 1:
The ejection process continues without interruption while straps are being applied. Multiple strapping units can operate simultaneously or in quick succession during the continuous ejection motion, eliminating the need to stop the ejection cycle between strap applications. This maintains bale security through multiple straps while removing the 10-second pause per strap, reducing total ejection time from potentially over a minute to a continuous rapid process
Solution Approach 2:
The strapping system transitions from static preset placement to dynamic adaptive placement. The number, position, and timing of strap applications can be adjusted based on bale characteristics, material type, and security requirements. This dynamic capability allows optimizing both bale security and ejection speed by adapting the strapping pattern rather than using fixed incremental ejection pauses
3Adaptability or versatility
If a single tying medium is used throughout the bale, then the tying system remains simple, but the adaptability to different material types and bale portions is reduced
Solution Approach 1:
The strapping system incorporates multiple strapping units that can apply different types of tying media (wire, plastic, or combination) to different portions of the same bale. Each strapping unit can be independently configured for specific material types, allowing the system to adapt to various recyclable materials and bale characteristics without requiring entirely different machines, thus achieving universality across material types while maintaining reasonable system complexity through standardized modular units
Solution Approach 2:
Different portions of the bale can receive different types of tying media based on local requirements. For example, wire straps can be applied to portions requiring high tensile strength while plastic straps are applied to portions where flexibility or corrosion resistance is needed. This local differentiation of tying medium properties enhances adaptability to various material types and bale portions while the modular strapping unit design keeps overall system complexity manageable

AI summary
A multiple strapping device that provides an uninterrupted ejection cycle for a bale while at the same time strategically placing the straps, or wire ties, onto the bale, through use of a series of corkscrews which hold the straps or wire ties and advance the strap, or wire ties, as the corkscrew is rotated therein releasing the strap, or wire ties, onto the bale.
