Solution Overview
Problem
Existing separating devices for transitioning from transverse to longitudinal transport of elongated goods are subject to high stress, and fail to efficiently manage the time interval between successive deliveries, especially when handling goods of different lengths.
Innovation Solution
A transport system utilizing screw conveyors with a conical base body, where the screw conveyors rotate in the same direction to minimize stress and optimize the distance between goods, allowing for adjustable rotational speeds to control the delivery interval and ensure uniform movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a throwing device is used to transfer piece goods from transverse to longitudinal transporter, then the piece goods can be transferred between transporters, but the piece goods and the system are subject to high stress
Solution Approach 1:
The patent replaces the throwing device (impact-based mechanical system) with a screw conveyor system that uses continuous gentle pushing motion. The screw conveyors transfer piece goods through continuous rotation rather than sudden throwing, substituting high-impact mechanics with low-impact continuous motion, thereby reducing stress on both piece goods and system components.
Solution Approach 2:
The patent changes the motion parameters from sudden high-velocity throwing to controlled continuous rotation. By adjusting the rotational speed of the screw conveyors, the system achieves efficient transfer while maintaining low stress conditions. The continuous rotation allows for parameter optimization that balances transfer speed with stress reduction.
2Ease of operation
If piece goods are stopped at the end of transverse transporter and thrown into longitudinal transporter, then transfer between transporters can occur, but the piece goods and system are subject to high stress
Solution Approach 1:
The screw conveyors act as an intermediary device between the transverse and longitudinal transporters. Instead of direct throwing from one transporter to another, the screw conveyors provide a intermediate transfer mechanism that gently receives piece goods from the transverse transporter and delivers them to the longitudinal transporter, eliminating the need for high-stress stopping and throwing operations.
3Loss of time
If the time interval between delivery of successive piece goods needs to be controlled, then separation can be managed, but with conventional devices the interval cannot be easily changed or optimized
Solution Approach 1:
The patent implements dynamic control of the screw conveyor rotational speeds, allowing the system to adapt the delivery interval to different operational requirements. By varying the rotation speed of the screw conveyors, the system can optimize the time interval between successive piece goods deliveries, providing both time management and operational flexibility.
Solution Approach 2:
The patent enables easy adjustment of the delivery interval by changing the rotational speed parameter of the screw conveyors. This parameter change allows the system to optimize separation timing and adapt to different piece goods lengths and throughput requirements, simultaneously addressing time interval control and system adaptability.
4Adaptability or versatility
If piece goods of different lengths are handled on the longitudinal transporter, then versatility is improved, but optimizing distance between piece goods becomes difficult
Solution Approach 1:
The patent uses dynamic speed adjustment of the screw conveyors to optimize the distance between piece goods of varying lengths. By continuously adapting the rotational speed, the system maintains optimal spacing regardless of piece goods length variations, enabling both versatile handling and precise distance control.
Solution Approach 2:
The patent achieves precise distance optimization by changing the rotational speed parameter of the screw conveyors based on the length of piece goods being handled. This parameter adjustment allows the system to maintain optimal spacing for different lengths while preserving versatility in handling various sizes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces stress on both the goods and the system during transition, enables precise control over the delivery interval, and ensures high throughput by uniformly accelerating goods, even those of varying lengths, while maintaining low operational forces.
Implementation Method 1
The piece goods are moved by continuous rotation of the screw conveyor, with the forces acting on the system being low as a result of the operation of the screw conveyor. The piece goods can be moved essentially uniformly
Implementation Method 2
By rotating the screw conveyors in the same direction, the piece goods can be driven in the longitudinal direction. This drive in the longitudinal direction can be used when transferring to a longitudinal transporter to build up a speed component in the direction of the longitudinal transporter
