Requirements and design specifications
Achieve 5 different tests on each yarn with a single instrument.
Simultaneously handle 24 types of different yarns.
Perform all the various tests automatically.
Machinery concept: analysis of the technical solutions available on the market and of the patented solutions.
Development of a proposal which allows to combine in a compact device the following types of tests:
– Yarn breaking test (dynamometer testing)
– Yarn hairiness test
– Yarn regularity test
– Measurement of the yarn count
– Roving regularity test
Machine development and realisation, from mechanical design and electrical and pneumatic installations to the assembly and start of the device.
Following the first series of prototypes, a review of the project and optimisation was performed, which included:
– New design of the mechanical part and software of the machine
– Reconfiguration of the old prototypes and realisation and assembly of 5 new devices
– Start and testing of the machine.
Development of control software for the device management.
Development of machine logic, HMI and internal machine database
Customer support service.
The innovation of this machinery, compared to what is present on the market, is related to the possibility of handling different input threads performing parallel tests on different yarns.
The various measuring instruments are placed at different points of the machine to ensure the automatic positioning of each yarn to the relevant instrument.
Designing an ad hoc manipulator for the application, whose purpose is to withdraw the yarn from a machine input area and lead it to the various test zones (none of the robots on the market had the required features to be integrated in the machine).
Ability to remotely access the device trials database.
This way it is possible to access trials with no time/space limitations and perform a series of statistic analyses on the results, filtering them according to type of material, type of processing, type of machine that has produced them, etc.
Development of data management, their graphical representation, and trials report generation.
The innovative aspects of this device have permitted the customer to deposit patents at European level.
