Vibratory Conveyor Exciter Bridging for Reliable Force Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor devices in material processing plants face challenges in efficiently transferring high forces from vibration exciters to support devices while maintaining a structurally simple and cost-effective design.
Innovation Solution
The motor stators of the exciter units are interconnected via a connecting element forming a bridging section, which reduces the stress on the fastening points and allows for a lighter, more efficient design by preventing relative motion between the motor stators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a massive support plate is used to transfer forces from vibration exciters, then force transfer reliability is improved, but device weight and structural complexity increase
Solution Approach 1:
The patent combines the support functions of multiple support points into a unified support structure that distributes forces across several locations. Instead of relying on a single massive support plate, the vibration exciter is supported at multiple points (at least two support points) that work together to transfer forces to the conveyor arrangement, reducing the need for excessive mass at any single location while maintaining overall reliability.
Solution Approach 2:
The support structure is segmented into multiple discrete support points rather than a single continuous massive plate. Each support point is independently dimensioned and positioned to handle specific portions of the forces generated by the vibration exciter, allowing for a lighter overall structure while maintaining adequate force transfer capability through distributed support.
2Reliability
If a massive support plate is used to transfer forces from vibration exciters, then force transfer reliability is improved, but structural simplicity and cost-effectiveness deteriorate
Solution Approach 1:
The patent merges the functions of multiple support elements into a coordinated support system where several simpler support points work together to achieve the same reliability as a single complex massive structure. This approach reduces structural complexity and cost while maintaining force transfer reliability through the combined action of distributed support points.
Solution Approach 2:
The support structure is divided into multiple simpler segmented elements rather than one large complex component. Each segment can be independently designed, manufactured, and positioned, reducing overall structural complexity and making the system more cost-effective while achieving adequate force transfer through the collective action of all segments.
3Strength
If fastening sections are heavily dimensioned to handle high forces, then force transfer strength is improved, but device weight and manufacturing cost increase
Solution Approach 1:
The fastening system is segmented into multiple separate fastening sections distributed at different support points rather than one or two heavily dimensioned fastenings. Each fastening section can be lightly dimensioned since the total force transfer requirement is distributed across multiple locations, reducing manufacturing cost and complexity while maintaining adequate overall strength.
Solution Approach 2:
The fastening sections are designed with local quality appropriate to the specific forces at each support location rather than uniformly heavy construction throughout. Each fastening section is dimensioned according to the local force requirements at its specific position, optimizing material usage and reducing overall manufacturing cost while maintaining necessary strength where needed.

AI summary
A conveyor device for a material processing plant includes a material conveyor section. A support device is coupled to the conveyor section, wherein the support device bears a vibration exciter having two exciter units, wherein the exciter units, each have an exciter motor which drives at least one imbalance mass using a motor rotor, wherein a fastening section is used to fasten the exciter units to the support device for vibration transmission. To make for a structurally simple design and improved force transfer from the vibration exciter into the support device the motor stators of the two exciter motors may be interconnected by means of at least one connecting element, wherein the connecting element forms a bridging area, which bridges the distance between the motor stators.
