Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping machines lack an efficient and reliable cut, clamp, and seam system for wrapping palletized loads, which complicates the process of cutting the film from the roll, holding the leading end, and attaching the trailing end to the load.
Innovation Solution
A wrapping machine with a cut, clamp, and seam system that includes a movable cut-and-seam assembly, an actuating assembly, and a film-release assembly, allowing for precise control between film-release, intermediate, and seaming configurations, enabling the machine to cut the film, hold the leading end, and attach the trailing end to the load without requiring a power supply on the turntable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cut, clamp, and seam system is added to the wrapping machine, then the film attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The cut, clamp, and seam system is divided into separate functional modules: a cut-and-seam assembly with cutting and seaming elements, a film-release assembly with release fingers, and an actuating assembly with links and actuators. Each module performs a specific function and can be independently controlled through different configurations, thereby improving film attachment reliability while managing system complexity through functional segmentation.
Solution Approach 2:
The system employs multiple movable components including the cut-and-seam assembly that can move between retracted and forward positions, the film-release assembly that transitions between engaged and disengaged states, and the actuating assembly with movable links. These dynamic elements allow the system to adapt its configuration during operation, ensuring reliable film cutting, clamping, and seaming while maintaining operational flexibility.
2Ease of repair
If power supply is removed from the turntable, then the ease of maintenance is improved, but the ability to power the cut, clamp, and seam system is reduced
Solution Approach 1:
An intermediary power transmission mechanism is introduced through the actuating assembly, which uses a series of links (first link, second link, third link, fourth link) to transmit mechanical motion from a stationary power source to the moving cut-and-seam and film-release assemblies. This intermediary linkage system eliminates the need for power supply on the rotating turntable while maintaining the ability to actuate the cutting, clamping, and seaming functions.
Solution Approach 2:
The patent replaces electrical power transmission (which would require power supply on the turntable) with a mechanical linkage system. The actuating assembly uses purely mechanical connections through multiple links and joints to transmit force and motion, substituting electrical systems with mechanical ones to simplify maintenance while preserving functional capability.
3Manufacturing precision
If multiple configurations are implemented for the actuating assembly, then the precision of film handling is improved, but the device complexity increases
Solution Approach 1:
The actuating assembly is designed as a universal mechanism that can achieve multiple configurations (first, second, and third configurations) through its linkage system. The same actuating assembly with its series of links serves multiple functions: positioning the cut-and-seam assembly, engaging the film-release assembly, and coordinating the cutting and seaming operations. This multi-functionality improves film handling precision across different operational phases while avoiding the need for separate mechanisms for each function.
