Solution Overview
Problem
Existing devices for separating rotationally symmetrical parts, such as closures and preforms, are prone to malfunctions and lack flexibility in controlling the separation process, leading to potential damage and inefficiencies in handling disruptions and defects detection.
Innovation Solution
A device with a rocker-type blocking assembly actuated by an actuator, allowing controlled pivoting movements to actively separate and position parts, enabling adjustable spacing and reliable detection of defects through optical and electrical inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If passive rocker-type blocking elements are used for separation, then the device structure is simple, but the separation process lacks control and reliability is poor
Solution Approach 1:
The patent replaces the passive mechanical rocker-type blocking system with an active electromagnetic actuation system. Electromagnets are positioned to interact with magnetizable blocking elements, allowing controlled movement between blocking and release positions. This substitution provides reliable, controllable separation while maintaining structural simplicity through the use of standard electromagnetic components.
2Productivity
If conventional separation devices are used, then parts are separated, but friction and contact damage occur during handling
Solution Approach 1:
The patent minimizes harmful mechanical contact by using electromagnetic fields to actuate the blocking elements. The electromagnets attract or release the magnetizable blocking elements without direct contact with the conveyed parts, significantly reducing friction and contact damage while maintaining effective separation capability.
3Ease of operation
If no active control is implemented, then the device is simple to operate, but disruption handling and defect detection are inefficient
Solution Approach 1:
The patent incorporates sensors that detect the presence and position of parts, providing feedback to the control system. This enables automatic adjustment of the blocking elements to handle disruptions and identify defects efficiently, while the centralized control maintains operational simplicity through automated decision-making based on sensor inputs.
4Device complexity
If adjustable spacing is not implemented, then the separation device is simpler, but flexibility for different processing requirements is reduced
Solution Approach 1:
The patent implements dynamic control of the blocking elements through electromagnetic actuation. The position and timing of the blocking elements can be adjusted in real-time to create variable spacing between parts, providing flexibility for different processing requirements while maintaining relatively simple device structure through programmable control.
