Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for transferring fish from a longitudinal direction to a transverse conveyor are limited by the maximum achievable conveying speed due to the upper limit of acceleration values, which restricts the reliability and efficiency of fish transfer, especially at higher conveyor speeds.
Innovation Solution
A device with multiple equidistantly spaced delivery devices and a control system that allows for intermittent and simultaneous transfer of fish into receiving elements at predetermined times, using acceleration units and a predefined acceleration profile to optimize the transfer process, decoupling it from the transverse conveyor speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the transverse conveyor speed is increased, then the conveying speed is improved, but the time window for fish transfer is reduced and higher acceleration values are required which cannot be exceeded due to mass inertia
Solution Approach 1:
The acceleration units accelerate the fish in the delivery devices before the transfer moment, so that the fish are already at the required speed when transferred to the receiving elements. This preliminary acceleration action allows the transfer to occur reliably even at high conveyor speeds without requiring excessive acceleration during the transfer itself.
Solution Approach 2:
The control device dynamically adjusts the activation timing of the delivery devices based on the actual conveyor speed and position of receiving elements. This dynamic control allows the system to adapt to varying speeds while maintaining reliable transfer by optimizing the acceleration profile and transfer moment.
2Speed
If the transverse conveyor speed is decreased, then the time window for fish transfer is extended, but the minimum ejection speed required for reliable transfer is not achieved
Solution Approach 1:
The acceleration units are activated in advance to build up the necessary ejection speed of the fish before the transfer moment. This ensures that even at lower conveyor speeds, the fish achieve the minimum required ejection speed for reliable transfer to the receiving elements.
Solution Approach 2:
The control device uses feedback from position sensors to monitor the actual speed and position of receiving elements, and adjusts the acceleration profile and transfer timing accordingly. This feedback mechanism ensures that the minimum ejection speed is always achieved while adapting to the actual conveyor speed.
3Productivity
If the delivery devices are activated more frequently, then the transfer frequency is increased, but the acceleration values required exceed the maximum permissible limits
Solution Approach 1:
The acceleration units perform preliminary acceleration of the fish in the delivery devices before transfer, so that the fish are already accelerated to the required speed. This allows more frequent transfers without exceeding maximum acceleration limits, as the acceleration is completed before the transfer moment rather than occurring during the transfer itself.
Solution Approach 2:
The control device dynamically adjusts the activation timing and acceleration profile of the delivery devices based on the actual conveyor speed and position. This dynamic control allows optimal transfer frequency while keeping acceleration values within permissible limits by adapting to real-time conditions.

Implementation Method 2
the acceleration units are completely mechanically decoupled from the transverse conveyor device, so that the process of accelerating the fish is independent of the conveying speed of the transverse conveyor
