Solution Overview

Problem

Existing equipment for changing tools, headpieces, and accessories in horizontal lathes requires multiple storage units and handlers, increasing complexity and cost due to the need for separate devices for different component sizes and weights, leading to inefficiencies in component exchange.

Innovation Solution

A single static storage unit and automated handling equipment with interchangeable handlers, featuring retention devices for fastening and positioning components between the storage unit and the lathe's machining spindle, reduces the number of necessary handlers and trips, enhancing precision and simplifying maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple storage units and handlers are used for different component types, then component exchange capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvecomponent exchange capabilityVSAvoidnumber of handlers
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal handler capable of handling multiple component types (tools, headpieces, accessories) through interchangeable retention devices. The handler can be configured with different retention devices depending on the component type, eliminating the need for separate specialized handlers for each component category while maintaining full handling capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The storage unit is divided into multiple compartments that can accommodate different component types, while a single handler service all compartments. The retention devices on the handler are segmented into interchangeable modules that can be selected based on the specific component being handled, allowing one handler to perform multiple functions.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If multiple storage units are used for different component sizes and weights, then handling precision is improved, but the number of trips and potential faults increase

Engineering Contradiction:
Improvehandling precisionVSAvoidnumber of trips
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

A single handler with interchangeable retention devices serves all storage compartments regardless of component type. The handler can be quickly reconfigured between different retention devices to match the current component being handled, maintaining precision while eliminating multiple trips between different storage units and handlers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The appropriate retention device is pre-selected and attached to the handler before approaching the storage unit. This preliminary configuration ensures the handler is ready for the specific component type, enabling precise handling in a single trip without needing to switch devices during the operation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If separate handlers are used for tools and headpieces, then component security is improved, but maintenance complexity increases

Engineering Contradiction:
Improvecomponent securityVSAvoidmaintenance complexity
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The retention devices are designed as segmented, interchangeable modules that can be independently selected and replaced. Each retention device type is optimized for specific component types (tools or headpieces), maintaining security and reliability, while the modular design allows individual devices to be maintained or replaced without affecting the entire handler system.

Inventive Principle:
Principle #1Segmentation

AI summary

Piece of equipment for exchanging components in horizontal lathes and a handler, referring to a piece of equipment equipped with one single static storage unit and a piece of automated handling equipment or a robot, which has manipulation means with various retention devices built in, in order to fasten the various components, such as tools, headpieces and accessories, to be moved, exchanged or positioned between two positions, preferably between the storage unit and the main machining spindle or axle of the horizontal lathe, although they may also be moved between the storage unit and a loading point or between the storage unit and an intermediate storage unit.
