Solution Overview

Problem

Existing conveyor systems face challenges in efficiently coordinating the transfer of sleeve-shaped workpieces between different conveyor devices with varying pitch configurations, leading to inefficiencies in production lines.

Innovation Solution

A transfer device equipped with a linear drive and gear arrangement, featuring pivoting workpiece grippers and an adjusting mechanism, allows for precise alignment and adaptation to different conveyor device pitches, enabling seamless transfer of sleeve-shaped workpieces between parallel-aligned mandrels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed pitch conveyor system is used, then the structure is simple, but it cannot adapt to different workpiece pitches and conveyor configurations

Engineering Contradiction:
Improveadaptation to different pitch configurationsVSAvoidcomplexity of transfer device
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transfer device employs a dynamically adjustable mechanism where the distance between the first and second workpiece grippers can be varied. This is achieved through a positioning device that can change the relative position of the grippers along the conveying direction, allowing the system to adapt to different pitch configurations between workpieces and between first and second conveyors while maintaining functional effectiveness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the spatial parameter (distance) between the workpiece grippers to adapt to different pitch configurations. By adjusting this distance parameter through the positioning device, the transfer device can accommodate various workpiece spacings and conveyor pitch variations without requiring complete redesign of the system architecture.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the distance between workpiece grippers is fixed, then the device is simpler, but it cannot accommodate different pitch configurations of conveyors

Engineering Contradiction:
Improvepitch configuration adaptabilityVSAvoidcomplexity of gear arrangement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gear arrangement incorporates a positioning device that enables dynamic adjustment of the distance between the first and second workpiece grippers. This positioning device may include mechanisms such as adjustable linkages, movable mounting positions, or reconfigurable gear configurations that allow the system to adapt to different pitch requirements while maintaining synchronized operation of the grippers.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If workpieces are transferred without pitch adjustment, then the transfer process is faster, but it cannot handle different conveyor divisions and pitches

Engineering Contradiction:
Improvecompatibility with different conveying devicesVSAvoidtime for pitch adjustment
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The positioning device is designed to adjust the distance between workpiece grippers in advance, before the actual workpiece transfer operation begins. This preliminary adjustment ensures that the grippers are properly positioned for the specific pitch configuration, allowing subsequent transfer operations to proceed efficiently without delays during the transfer itself.

Inventive Principle:
Principle #10Preliminary action
