Two-Track Belt Conveyor for Compact Lateral Portion Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lateral overlapping systems for food product portions are space-consuming, complex, and expensive due to the need for multiple independent belt conveyors and rocker mechanisms, making them unsuitable for versatile and cost-effective use, especially for smaller batches.
Innovation Solution
A belt conveyor system with two tracks that are deflected around a common input axis and two output axes at different heights, allowing for lateral overlap without additional equipment, and can be driven by a single motor, enabling a modular and adjustable design for various overlap patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rocker mechanisms and multiple independent belt conveyors are used for lateral overlapping, then reliable portion stacking is achieved, but device complexity and installation space increase significantly
Solution Approach 1:
The patent merges the functions of multiple independent belt conveyors and rocker mechanisms into a single integrated belt conveyor system with two tracks. The common drive shaft unifies the driving mechanism, eliminating the need for separate drives for each conveyor and rocker assembly, thus reducing device complexity while maintaining reliable portion stacking functionality.
Solution Approach 2:
The single belt conveyor system with two tracks serves multiple functions simultaneously: it transports portions, directs them to different height levels, and enables lateral overlapping all within one integrated structure. This multi-functional design replaces the need for separate specialized components (rocker mechanisms, multiple conveyors), reducing overall system complexity.
2Ease of operation
If multiple independent belt conveyors and rocker mechanisms are deployed, then precise portion direction control is achieved, but manufacturing cost increases
Solution Approach 1:
By combining multiple independent conveyors and rocker mechanisms into a single belt conveyor system with a common drive shaft, the patent reduces the number of components that need to be manufactured, assembled, and maintained. This integration lowers manufacturing costs while preserving the ability to precisely control portion direction through the track configuration.
3Adaptability or versatility
If long conveyor systems (3-4m) are used for lateral overlapping, then sufficient overlapping space is provided, but installation space requirements increase
Solution Approach 1:
The patent utilizes vertical dimension by deflecting the belt conveyor to different height levels (upper and lower tracks at different heights). This allows lateral overlapping to occur in three-dimensional space rather than requiring extended horizontal distance, thereby reducing the installation footprint while providing sufficient overlapping space.
Solution Approach 2:
The belt conveyor incorporates curved deflection paths to transition between different height levels and track configurations. These curved sections allow compact turning and height changes within a limited space, enabling the system to achieve necessary overlapping movements without requiring long straight conveyor sections.
4Productivity
If independent drives are provided for each conveyor level and rocker mechanism, then precise speed control is achieved, but device complexity and cost increase
Solution Approach 1:
The patent employs a single common drive shaft that powers both the upper and lower belt conveyor tracks. This unified driving system reduces the number of motors and control mechanisms required, simplifying the drive system while maintaining the ability to control speeds precisely through the mechanical transmission ratio and conveyor configuration.
