The present invention is related to the technical field of Mechanical and Electrical, since it provides a machine and a system to make cuts, preferably cuts in protective films that cover laminar pieces.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
El remover las películas que envuelven a piezas laminares, ha sido complicado, lento, y se sigue requiriendo la misma cantidad de mano de obra. Para tratar de solucionar este problema, se han desarrollado tecnologías para las cortar películas plásticas que envuelven a las piezas laminares, pero dichas tecnologías aún siguen siendo deficientes, debido a que hacen solo la función de cortar las películas, pero para ello se debe colocar y sujetar las piezas laminares en la posición adecuada para que el corte sea adecuado, lo cual se sigue haciendo manualmente. Removing the films that surround laminar pieces has been complicated, slow, and continues to require the same amount of labor. To try to solve this problem, technologies have been developed to cut plastic films that wrap the laminar pieces, but these technologies are still deficient, because they only serve the function of cutting the films, but for this they must be placed and hold the laminar pieces in the proper position for proper cutting, which is still done manually.
Además, las máquinas, aparatos o dispositivos que actualmente se utilizan para hacer el corte de las películas protectoras son estándares ya que sólo pueden cortar las películas protectoras de piezas laminares de un solo tamaño y forma; por lo que cuando las piezas son diferentes, se tiene que usar o fabricar otra máquinas, aparatos o dispositivos. Furthermore, the machines, apparatus or devices currently used to cut protective films are standard since they can only cut protective films from laminar pieces of a single size and shape; so when the parts are different, other machines, devices or devices have to be used or manufactured.
