Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic packaging machines require complex and time-consuming setup processes for movable operating members, which are often performed by technical experts and result in poor repeatability and inefficiency, leading to variations in machine performance and difficulties in troubleshooting and after-sales support.
Innovation Solution
A method for setting up movable operating members of automatic machines that involves modifying the motion profile of electric actuators using an interface device, allowing operators to adjust the motion profiles directly, thereby correcting imperfections and improving precision without the need for mechanical adjustments or external expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If technical experts perform manual setup operations (calibration, filing, shimming) on movable operating members, then processing precision can be achieved, but the setup process becomes time-consuming and shows poor repeatability
Solution Approach 1:
The patent replaces manual mechanical setup operations (filing, shimming, calibration) with an automated control system that adjusts movable operating members through electronic actuators. The control unit receives target position data and automatically positions components, eliminating the need for technical experts to perform time-consuming manual adjustments while maintaining high precision and improving repeatability across different machines.
2Manufacturing precision
If manual setup operations are performed ad hoc for each machine, then individual machine precision can be optimized, but variability between machines increases
Solution Approach 1:
The patent implements a universal setup system where the control unit can load and execute the same motion profile data across multiple identical machine instances. This allows precise setup parameters developed for one machine to be replicated universally across all machines of the same model, ensuring consistent performance and eliminating ad hoc variations while maintaining individual precision through the standardized control approach.
3Manufacturing precision
If mechanical parts are modified through filing and milling during setup, then motion profile precision is improved, but the complexity of maintenance and troubleshooting increases
Solution Approach 1:
The patent replaces static mechanical modifications (permanent changes through filing and milling) with dynamic, software-based adjustments. The control unit can modify motion profiles and actuator parameters without any physical alteration to mechanical parts. This maintains precision while significantly reducing maintenance complexity, as software parameters can be adjusted remotely and do not require disassembly or specialized mechanical skills for troubleshooting.
4Productivity
If setup operations are performed without logging, then setup speed may be maintained, but troubleshooting and after-sales support become inefficient
Solution Approach 1:
The control unit automatically logs all setup operations, parameter adjustments, and motion profile configurations to a database or storage medium. This creates a feedback loop where setup information is captured and made available for future reference, troubleshooting, and after-sales support. The logging occurs without interfering with setup speed, as it is performed automatically by the control system rather than requiring manual documentation.

AI summary
A method to set up at least one moveable operating member of an automatic machine for manufacturing consumer articles and comprising the steps of defining a first motion profile of the movable operating member and defining a corresponding second motion profile of an electric actuator system, which moves the moveable operating member with the first motion profile. The method calls for the further steps of: determining possible imperfections in the processing of the articles caused by the movable operating member; correcting, by means of an interface device and on the basis of the possible imperfections, the first motion profile, thus obtaining a first changed profile of the moveable operating member; and calculating, through a control unit, a reverse kinematics of the first changed profile so as to obtain a corresponding second changed profile to be commanded to the electric actuator system.
