Industry 4.0 has expanded the alternatives to design more sustainable processes. Among the technologies of this industrial phase, IoT (Internet of Things) technology allows the linkage of devices that generate data at high volumes (big data), supporting the creation of Artificial Intelligence (AI) models to perform optimal operating standards to minimize waste in the production. By means of vision sensor and AI deployment, this study aimed to reduce the polybutylene plastic waste in an extrusion line of colored tubes, in which most of the waste is generated during the color transition. For that, a vision sensor that transfers the tube color in real-time was installed, which made it possible to set acceptance ranges for the standard colors of the tubes based on the elicitation of the operators' knowledge. These ranges allowed the setup of an expert system that warns the operator, by a light signal, the right time to start the production. The suggested technology demonstrated to be 11.47% more efficient in waste reduction in color transitions. It also allowed the identification of the requirements for the deployment of this technology in plastic extrusion, so it can promote overall waste reduction, which requires improvements in operation, standardization, and employee training.

resumo ...
Viscoelastic supports (VES) are bearing-foundation systems containing viscoelastic materials with high capacity of vibration energy dissipation. The application of VES on rotating machinery allows for a safe operation around critical speeds while suppressing peaks of vibration amplification. This paper presents an experimental validation of a multi-degree-of-freedom (multi-DOF) VES independently designed with regards to viscoelastic stiffness in translational and rotational DOF. An optimal design of the multi-DOF VES is obtained using a methodology developed in previous works and a prototype is constructed and integrated into the rotating system to be experimentally validated. Run-down measurements were carried out and compared with the frequency unbalance response numerical predictions. The run-down measurements exhibit excellent agreement with numerical predictions, particularly in terms of frequency accuracy. These results highlight the effectiveness of the optimally designed multi-DOF VES in controlling the unbalance frequency response over the entire spin speed range of a dual-disc rotating system. This leads to a significant reduction in response amplitude at critical speed when compared to the rotating system supported on rigid bearings. The experimental validation of the multi-DOF VES demonstrates its capability to enhance the performance and safety of rotating machinery operating around critical speeds. The optimized design effectively mitigates response amplitudes at critical speeds, validating the methodology presented in previous works. The findings underscore the practical applicability of the proposed approach, positioning the multi-DOF VES as a valuable tool for controlling the unbalance frequency response in rotating systems.
