Abstract: A bending machine has an automated profile bending process for providing controlled management, regulation of the controlled management, correction of the automated profile bending process, and application of 3D cameras to the bending machine. The bending machine includes a first camera fixed to a first holder and a second camera fixed to a second holder. The bending machine further includes rollers for applying the holders to the bending machine to provide a three-dimensional view of a portion of the bending process. The bending machine even further includes a computer for controlling the bending process, and the bending process includes a profile defined dimensionally and in space relative to the bending machine.

Abstract: The application of the 3D cameras during the profile bending process on the bending machine with three and four rollers provides controlled management, regulation of control as well as correction of the bending process, where the application of the 3D cameras (1) and (2) provides a three-dimensional view of the bending process and each point of interest on the machine (3) and on the profile (4) is defined dimensionally and in space. Utilizing the 3D cameras (1) and (2) during the bending process the profile (4) is detected, thus implementing a feedback loop between the computer (7) controlling the bending process and the profile (4) bent on the machine (3).

Abstract: PVC profile bending using laser and PLC controlling system is a part of the arched PVC joinery, where the bending of the PVC profiles is completely automatized thus removing any possible human error caused by operating the machine manually. PLC controlling system includes encoder with a wheel X (4) and encoder Y (6), which send the information about the rotating speed of the motor X (4.1) and Y (6.1) to the PLC unit, where the rotating speed of the motor X is controlled using regulator of frequency (41) which is, same as the terminal (7), connected to the PLC unit using bidirectional connection, Laser system set in the plastic box (3) includes laser emitter (3.1) which releases beam reflected by the mirror foil (14) set on the profile (10) back to the photodiodes (3.
