Variable Speed Conveyor Cam Mechanism for Egg Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveying systems for shock-sensitive items like eggs fail to minimize the risk of damage during transfers between conveying devices, particularly from horizontal to vertical orientations, due to sudden movements and shocks.
Innovation Solution
A motion transmission system is implemented to synchronize the movement of conveying devices, using a cam wheel with cam profiles to transform constant speed motion into accelerated and decelerated motion, ensuring smooth transfers by controlling the speed of conveyor belts to minimize shocks, and a discharging device with pivotable plate elements to handle foreign objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eggs are transferred from horizontal conveyor belts to vertical conveying devices at constant speed, then transfer efficiency is maintained, but eggs are subjected to sudden movements and shocks causing damage
Solution Approach 1:
The patent applies dynamics by transforming the constant speed motion of the vertical conveying device into variable speed motion for the horizontal conveyor belt through a cam mechanism. The conveyor belt speed varies periodically, reaching minimum values during egg transfer moments and maximum values between transfers, thereby dynamically adjusting speed to eliminate shocks while maintaining continuous operation and transfer efficiency.
Solution Approach 2:
The patent changes the speed parameter of the horizontal conveyor belt from constant to variable through the cam mechanism. By periodically varying the speed parameter - reducing it to minimum during transfer operations and increasing it to maximum between transfers - the system achieves both egg protection and maintained productivity.
2Reliability
If the speed of the horizontal conveyor belt is reduced to minimum during transfer, then egg damage risk is minimized, but transfer time increases
Solution Approach 1:
The patent implements periodic action through the cam mechanism that rhythmically varies the conveyor belt speed. The belt operates at minimum speed during egg transfer moments and accelerates to maximum speed between transfers. This periodic variation in speed ensures egg safety during critical transfer moments while minimizing time loss by rapidly resuming high-speed operation afterward.

Function Achieved in This Case
The system effectively reduces the risk of egg damage during transfers by ensuring smooth transitions between conveying devices, maintaining egg safety and preventing shocks, and allows for efficient handling of foreign objects.
Implementation Method 1
a cam wheel, comprising one or more cam profiles: thanks to the provision of said cam profiles, the motion at constant speed transmitted by the second conveying device to the cam wheel is transformed into an accelerated and decelerated output motion transmitted from the cam wheel to the first conveying device

AI summary
The present invention relates to a conveying system (1) for shock-sensitive items, in particular eggs, which comprises a plurality of conveying devices (101, 201, 301) and in which said items are transferred from a conveying device to another one. More particularly, the present invention relates to a conveying system (1) in which said items are transferred from a conveying device (101) oriented in a substantially horizontal direction to an adjacent conveying device (201) oriented in a substantially vertical direction, without the risk of being damaged. According to the invention, the advancing movement of the conveying device having a substantially horizontal orientation (101) is not a movement at constant speed but, on the contrary, it is a movement at variable speed, sometimes accelerated and sometimes decelerated, and the transfer of the conveyed item from said conveying device to the conveying device having a substantially vertical orientation (201) takes place when the advancement speed of said conveying device having a substantially horizontal orientation (101) is at its minimum value.
