Abstract

The objective of the curricular integration research Project was to repower the vaporizer machine for shoe tip assembly at Creaciones Jimmy's company. To achieve this goal, a technical assessment of the machine's condition was conducted, identifying the need for maintenance on the structure; the pneumatic, hydraulic, and heating systems were identified, while the control and command, electrical and sensor systems required replacement. Based on these analyses, the requirements were defined, in addition to carrying out the design of the project conception. The systems were maintained and replaced, for which a programmable logic module and an HMI screen were incorporated to improve the machine control. Additionally, the flexibility of material selection and workstation was added. For the validation of the temperature sensors, accuracy tests were conducted, showing a maximum absolute error of ±1.1°C and a relative error of 5.17%. These results indicated that the sensors' accuracy is within acceptable limits. From the vaporization time test, a maximum relative error of 0.12% was obtained, demonstrating excellent precision in the timing. In the stability tests in the heating time of the plates, a coefficient of variation of 7.38% was obtained, confirming its acceptability. In conclusion, the repowered vaporizer machine meets the requirements for the vaporization process, achieving a significant cost saving of 33.32% compared to commercially available equipment with similar features. It is recommended to conduct a technical assessment of other machines within the company, precisely the shoe cooling machine, to optimize resources.
