Adjustable Vacuum Suction Device for Dynamic Part Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for separating parts in multiple rows cannot adjust the distance between holding elements, limiting their ability to change the lateral spacing of parts during transfer, which is particularly problematic when parts are initially adjacent and require spacing for further processing.
Innovation Solution
The device employs longitudinal and transverse guide rails that allow the holding elements to change their lateral distance during transport, enabling adjustable spacing without requiring additional machine steps, and includes rotatable transverse guide rails for efficient part movement and vacuum suction cups connected via telescopic lines for reliable part handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the holding elements are fixedly arranged on a rotatable element, then the device structure is simple, but the distance between holding elements cannot be changed
Solution Approach 1:
The holding elements are made dynamically adjustable through guide rails that allow changing their lateral distance from a first distance for pickup to a second distance for deposition, enabling the device to adapt to different part spacing requirements while maintaining operational simplicity
Solution Approach 2:
The device is segmented into multiple guide rails (first and second guide rails) that can independently adjust the position of holding elements, allowing flexible distance modification without requiring complete structural redesign
2Adaptability or versatility
If the distance between holding elements is changed during transport, then part lateral spacing can be adjusted, but the device complexity increases
Solution Approach 1:
The adjustment mechanism operates in the lateral dimension perpendicular to the transport direction, allowing distance changes between holding elements without interfering with the primary transport function, thus adding capability with minimal complexity increase
3Productivity
If multiple transverse guide rails are used for simultaneous part handling, then productivity increases, but the device complexity and control difficulty increase
Solution Approach 1:
Multiple transverse guide rails are merged into a coordinated system where all rails follow the same operational pattern (moving between first and second positions), allowing simultaneous part handling while maintaining uniform control logic that prevents exponential complexity increase

AI summary
The apparatus has a transfer element including two vacuum suction devices (2) arranged adjacent one another for picking up parts from a position and depositing the parts in another position. An adjusting unit adjusts distance between the devices, during transport of the parts. The adjusting unit is formed as a longitudinal guide track (3) with which the devices are operatively associated. The devices are operatively associated with transverse guide tracks that are adjustable along the longitudinal guide track at different speeds.
