Automated Tray Sealer Module Replacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tray sealers require cumbersome and time-consuming manual processes for replacing cutting and sealing modules, especially when dealing with multiple rows of trays, which complicates maintenance and format changes, and poses safety risks due to the need for manual handling of hot modules.
Innovation Solution
The implementation of mechanical engaging means with vertical movement and a template with thermo-insulating handles allows for quick and safe removal and installation of cutting and sealing modules, utilizing a vertical electric plug system that automatically disconnects during module extraction, enabling automated and efficient replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If manual replacement of cutting and sealing modules is used, then maintenance can be performed, but the process is time-consuming and requires wide free space
Solution Approach 1:
The module replacement system transitions from static manual handling to dynamic automated movement. The lifting mechanism with vertical guides and electric motors automatically raises and positions modules, while the conveyor system transports them between stations. This dynamic automation eliminates manual labor and significantly reduces replacement time.
Solution Approach 2:
The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.
2Ease of repair
If manual handling of hot modules is performed, then module replacement is possible, but safety risks due to burns increase
Solution Approach 1:
The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.
Solution Approach 2:
The patent replaces manual mechanical handling with automated mechanical systems. Electric motors drive the lifting mechanisms and conveyor belts, substituting human operators with automated equipment that can safely handle hot modules without burn risk.
3Ease of operation
If drawer-like sliding solution is used for module mounting, then module access is facilitated, but wide free space on machine sides is required
Solution Approach 1:
The patent moves the module access problem from horizontal sliding (requiring side space) to vertical lifting (using overhead space). The lifting mechanisms with vertical guides raise modules upward, and the conveyor system transports them horizontally at elevated positions, eliminating the need for wide free space on machine sides.
Solution Approach 2:
The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.
4Adaptability or versatility
If modules are mounted on hooking plate, then format changes are facilitated, but manual connection and disconnection of electrical systems is required
Solution Approach 1:
The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.
Solution Approach 2:
The automated lifting and conveyor system performs the module replacement service itself without human intervention. The system automatically raises modules, transports them to transfer stations, and facilitates electrical connection/disconnection, making the system self-sufficient in the replacement process.
