Servo Press Conveyor Motion Planning for Offset and Power Peaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In servo press installations, the conventional angle-based programming of conveyor systems leads to increased time required for material handling, which can result in slower pressing speeds and reduced productivity due to the need for longer offsets between presses.
Innovation Solution
A method for motion planning that calculates a motion curve for the conveyor system outside the pressing workspaces of the servo presses, allowing for a specific time interval to complete the conveyance without affecting loading and unloading processes, thereby optimizing the offset between presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the offset between presses is increased to allow for conveyor system conveyance time, then the conveyor system can complete material transfer, but the press must provide more time for loading and unloading which results in slower pressing speed
Solution Approach 1:
The conveyor motion is divided into multiple positioning sets instead of a single positioning set. The first positioning set handles the initial conveyance from the first press, while the second positioning set handles the subsequent conveyance to the second press. This segmentation allows the offset between presses to be extended without proportionally increasing the total conveyance time, as each positioning set can be optimized independently. The segmentation enables the press to maintain higher pressing speeds while the conveyor system completes material transfer through coordinated multiple positioning actions.
2Productivity
If the conveyor system executes transfer rapidly to increase productivity, then less time is required for material handling, but the offset between presses must be reduced which limits energy management optimization
Solution Approach 1:
The system employs dynamic motion planning where the conveyor apparatus executes different motion profiles depending on the phase of operation. During the forward motion phase, the conveyor operates at high speed to minimize transfer time and maximize productivity. During the return motion phase, the conveyor can operate at reduced speed or perform energy recovery braking. This dynamic approach allows the offset duration to be extended for energy management optimization while maintaining rapid transfer speeds during the critical material handling phase. The motion controller adjusts velocity and acceleration parameters in real-time to balance productivity requirements with energy management goals.
