Handling Machine Actuator Speed Control via Dynamic Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handling machines, such as turret-type rotating handlers, face challenges in adjusting their setup to match varying environments and accessories, which affects safety and stability, particularly when operating with heavy or bulky loads and in confined spaces.
Innovation Solution
A method and system for adjusting the setup of handling machines by setting maximum operating speeds for actuators and enforcing control laws to ensure these speeds are not exceeded, using a memory storage system integrated with the control station to recognize accessories and adapt control laws accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the handling machine operates at high speed for improved productivity, then productivity increases, but safety and stability deteriorate when handling heavy or bulky loads
Solution Approach 1:
The patent implements dynamic speed adjustment by allowing the operator to set maximum speeds for each actuator individually. The control system enforces these speed limits adaptively based on the specific operational context, enabling the machine to operate at optimal speeds for different tasks while maintaining safety. This is achieved through the method of setting maximum speeds for actuators (step a), storing these settings (step b), and forcing the machine to follow control laws that respect these limits (step c).
Solution Approach 2:
The patent changes the operational parameters by introducing configurable maximum speed settings for each actuator. Instead of operating at fixed high speeds, the system allows parameter adjustment where each actuator's maximum speed can be independently set and enforced. This enables the handling machine to adapt its speed parameters to match the specific requirements of different loads and operational environments, thereby maintaining both productivity and safety.
2Ease of operation
If the handling machine uses fixed control laws for simplified operation, then ease of operation improves, but adaptability to different environments and accessories deteriorates
Solution Approach 1:
The patent applies preliminary action by allowing the operator to pre-configure maximum speed settings for each actuator before operation. The control system stores these pre-set limits and automatically enforces them during operation. This preliminary configuration enables the machine to adapt to different environments and accessories without requiring complex real-time adjustments, maintaining ease of operation while improving adaptability.
Solution Approach 2:
The control system achieves universality by implementing a flexible framework that can accommodate different maximum speed settings for various actuators and operational scenarios. The same control system enforces speed limits across multiple actuators (turret rotation, boom elevation, telescopic extension, etc.), allowing the machine to adapt to different accessories and environments through parameter configuration rather than requiring different control systems.

AI summary
A method is provided for adjusting a handling machine (1) involves moving a control member (2) for controlling an actuator (7) or a motor (11) to adjust a maximum operating speed of the actuator (7) or motor (11) tool. The method includes memorizing a maximum speed setting in a suitable memory (4), and subjecting the work of the handling machine (1) to a control law, not exceeding the memorized maximum speed of operation. The method is applied of the adjustment method to a handling machine (1) including a plurality of actuators (7, 9, 11, 13, 15) and at least one actuator control member (2, 3).
