Mincing Machine Safety Device Automatic Electrical Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mincing machines pose safety risks during maintenance and cleaning operations due to potential sudden activation of rotating blades, and current methods for insulation from electrical supply are not fully efficient, necessitating complete disconnection for safety compliance.
Innovation Solution
An automated safety device with a linear mechanized movement allows for simple pressure-activated connection and insulation of the electrical supply at the mincing mouth, using a rod and elastic device to ensure safe disconnection during maintenance and automatic reconnection upon completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mincing machine is disconnected from electrical supply during maintenance, then operator safety is improved, but operational efficiency deteriorates due to manual disconnection requirements
Solution Approach 1:
The system automatically disconnects and reconnects electrical supply without operator intervention. The microswitch mechanism self-activates when the mincing mouth is removed, cutting power automatically, and self-reconnects when the mouth is reinstalled, eliminating the need for manual disconnection while ensuring operator safety.
Solution Approach 2:
The electrical disconnection action is performed in advance of the actual maintenance work. As soon as the mincing mouth begins to be removed, the rod triggers the microswitch to cut power before the operator fully disassembles the unit, preventing any risk of accidental activation during the maintenance process.
2Ease of operation
If the mincing mouth is easily removed for cleaning, then ease of operation is improved, but risk of accidental activation increases
Solution Approach 1:
The rod acts as an intermediary element between the mincing mouth and the electrical supply system. When the mouth is removed, the rod moves and triggers the microswitch, mediating the connection between mechanical disassembly and electrical disconnection to prevent accidental activation while maintaining ease of operation.
Solution Approach 2:
The system applies preliminary anti-action by automatically cutting electrical power as soon as the mincing mouth begins to be removed. This counteracts the potential harmful effect of accidental blade activation before it can occur, allowing operators to work safely on exposed components.
3Reliability
If automated safety device is added to mincing machine, then operator safety is improved, but device complexity increases
Solution Approach 1:
The safety mechanism is merged with the existing mincing mouth assembly. The rod is integrated into the mincing mouth structure, and the microswitch is combined with the electrical supply system, creating a unified safety device that leverages existing components rather than adding separate complex systems.
Solution Approach 2:
The safety device uses simple, inexpensive components such as a basic rod and a standard microswitch. These are straightforward mechanical and electrical elements that are easy to manufacture, install, and replace, avoiding the need for complex electronic control systems or expensive safety mechanisms.
