Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems face reduced throughput and increased risk of damage due to the need for extensive piston and cylinder device strokes to accommodate varying product widths, leading to inefficiencies and safety hazards.
Innovation Solution
A conveyor system with an adjustable ejector base position, allowing the ejector's end region to project into the transport surface by up to half or more of the conveyor width, reducing the required stroke and minimizing the ejector's length, thereby enhancing throughput and safety by reducing the risk of damage and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the piston and cylinder device extends to its maximum stroke to cover the entire conveyor width, then the pusher plate can reach and divert products across the full width, but the device impedes the product flow and reduces throughput
Solution Approach 1:
The ejector base position is made adjustable in the transverse direction, allowing the system to dynamically adapt its position according to the actual product flow width. This enables the ejector to be optimally positioned for each sorting task, reducing unnecessary travel distance while maintaining full coverage capability when needed.
Solution Approach 2:
The invention changes the parameter of ejector base position from fixed to variable. By adjusting the base position parameter in the transverse direction, the system optimizes the ejector's starting position relative to the product flow, thereby reducing the required stroke length and improving throughput without sacrificing adaptability.
2Adaptability or versatility
If the piston and cylinder device uses a maximum stroke to accommodate varying product widths, then the pusher plate can divert products across the entire width, but the minimum length of the piston rod increases the area required in the transverse direction
Solution Approach 1:
The ejector base position is made adjustable in the transverse direction, allowing the system to dynamically adapt its position according to the actual product flow width. This enables the ejector to be optimally positioned for each sorting task, reducing unnecessary travel distance while maintaining full coverage capability when needed.
Solution Approach 2:
Instead of increasing the piston rod length in the transverse direction to achieve maximum stroke coverage, the invention shifts the solution to another dimension by adjusting the base position of the entire ejector assembly. This dimensional shift allows the same stroke length to cover a larger effective range by changing the starting position rather than extending the component itself.
3Adaptability or versatility
If the piston rod is made long to accommodate the maximum stroke, then the ejector can reach across the entire conveyor width, but the projecting rod presents a risk of accident and can become accidentally damaged
Solution Approach 1:
The ejector base position is made adjustable in the transverse direction, allowing the system to dynamically adapt its position according to the actual product flow width. This enables the ejector to be optimally positioned for each sorting task, reducing unnecessary travel distance while maintaining full coverage capability when needed.
Solution Approach 2:
The base position of the ejector is adjusted in advance according to the expected product flow characteristics. This preliminary positioning ensures that the ejector starts from the optimal position, minimizing the required stroke and piston rod projection, thereby preventing safety hazards before they occur.
4Force
If an air blast nozzle generates high air pressure to divert products maximally far away, then the ejection force is sufficient, but the reaction time up to ejection increases and throughput is reduced
Solution Approach 1:
The ejector base position is made adjustable in the transverse direction, allowing the system to dynamically adapt its position according to the actual product flow width. This enables the ejector to be optimally positioned for each sorting task, reducing the distance to the target position and thereby reducing reaction time while maintaining sufficient ejection force.
Solution Approach 2:
The invention changes the parameter of ejector base position to optimize the starting position for air blast nozzles. By adjusting this parameter, the system reduces the distance over which air pressure must act, decreasing reaction time while maintaining the necessary ejection force for effective product diversion.
5Force
If an air blast nozzle generates high air pressure to divert products maximally far away, then the ejection force is sufficient, but noise generation increases and is perceived as disruptive
Solution Approach 1:
The ejector base position is made adjustable in the transverse direction, allowing the system to dynamically adapt its position according to the actual product flow width. This enables the ejector to be optimally positioned for each sorting task, reducing the distance to the target position and thereby reducing reaction time while maintaining sufficient ejection force.
Solution Approach 2:
The invention changes the parameter of ejector base position to optimize the starting position for air blast nozzles. By adjusting this parameter, the system reduces the distance over which air pressure must act, decreasing both reaction time and the noise generated during ejection, while maintaining sufficient ejection force.

The adjustable ejector design enables faster sorting and reduced noise generation, increasing conveyor system efficiency and safety by minimizing the projection of the piston rod and reducing the need for high air pressure, thus enhancing overall performance and reducing operational risks.
Implementation Method 1
the air pressure generated at the exit orifice (at the nozzle) must have an appropriate force to divert even products that are maximally far away

AI summary
A belt conveyor is configured for conveying products in a conveying direction and defines a width extending in a transverse direction orthogonal to the conveying direction, and a height direction orthogonal to the conveying and transverse directions. An ejector is fixed to the belt conveyor and acts in the transverse direction for sorting out/discharging products. The ejector has an end region which faces the product to be sorted out, and has a base body mounted in a base position on the belt conveyor by means of a holder. The basic position of the base body can be adjusted by means of an adjusting device of the holder in the transverse direction within an adjustment path so that the end area of the non-actuated ejector in the transverse direction can protrude across the belt conveyor width by at least half of that width, or more.
