Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating conveyors face challenges in adapting to the properties of objects being conveyed, such as weight, size, and surface friction, due to fixed stroke and speed limitations, making them less versatile and requiring manual handling in space-constrained environments like near eccentric presses, and they often produce high noise levels and reverse conveying directions.
Innovation Solution
An oscillating conveyor with a crank mechanism featuring an adjustable pendulum pin that varies triangle angles, allowing for adjustable displacement speed, combined with a compact AC motor and a curved connecting rod for optimal geometry and reduced collision risks, enabling easy adaptation to different objects and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed stroke crank mechanism is used, then the structure is simple, but the adaptability to different objects is poor
Solution Approach 1:
The patent applies the dynamics principle by making the pendulum pin position adjustable rather than fixed. This allows the crank mechanism to adapt its geometry dynamically to different objects being conveyed, enabling variation in oscillation frequency and stroke length without changing the entire mechanism structure.
Solution Approach 2:
The patent implements parameter changes by allowing adjustment of the pendulum pin position along the crank circle, which changes the triangle angles and thereby modifies the oscillation characteristics (frequency and stroke) of the conveying element to match different object properties.
2Productivity
If the conveying element moves quickly to the second extreme position, then productivity increases, but the risk of object damage increases
Solution Approach 1:
The patent applies periodic action by creating an asymmetric oscillation pattern where the conveying element moves quickly to the second extreme position and then returns slowly to the first extreme position. This periodic motion pattern allows rapid progression in the desired direction while providing a controlled, slower return that prevents object damage.
Solution Approach 2:
The patent implements asymmetry by designing the crank mechanism with asymmetric triangle geometry through adjustable pendulum pin positioning. This creates unequal acceleration and deceleration phases, allowing fast movement in one direction while maintaining slower, safer movement in the return direction.
3Area of stationary object
If a vibrating conveyor is used, then space utilization is improved, but noise levels become very high
Solution Approach 1:
The patent replaces the high-frequency vibration mechanism with a low-frequency oscillation mechanism driven by a crank and connecting rod system. This mechanical substitution maintains the space-saving benefits of compact conveyor design while dramatically reducing noise levels through the use of smoother, lower-frequency motion.
4Adaptability or versatility
If the pendulum pin position is fixed, then the structure is simple, but the adaptability to different objects is limited
Solution Approach 1:
The patent applies dynamics by making the pendulum pin position adjustable rather than fixed. This allows the crank mechanism to adapt its geometry dynamically to different objects being conveyed, enabling variation in oscillation frequency and stroke length without changing the entire mechanism structure.

AI summary
The invention relates to an oscillating conveyor (1), which comprises a support (2), a conveying element (3), that is arranged to carry objects to be moved and is supported by the support (2) in order to be displaced to and fro between a first extreme position and a second extreme position, and a driving means (4), which is arranged on the stand (2) in order to displace the conveying element (3) to and fro. A driving means (4) is arranged to displace the conveying element (3) relatively slowly to the first extreme position and to displace it relatively quickly to the second extreme position in order thereby to achieve a movement of the objects in a direction, which corresponds to a displacement direction of the conveying element from the second extreme position to the first extreme position. The driving means (4) includes a crank mechanism (5), which comprises a pendulum pin (15), which in relation to a rotational axis (7) of the crank mechanism (5) is mounted such that, when the crank (6) rotates, at the pendulum pin ( 15) an angle between the axis of rotation (7) and a first pivot pin (12) varies within an angular range being either obtuse or acute, resulting in the desired displacement of the conveying element (3) at different speeds to and fro, wherein the position of the pendulum pin (15) in relation to the rotational axis (7) is adjustable, thus enabling a variation of the displacement speed of the conveyor element (3).
