Abstract

The present disclosure relates to a winder control device having a multi-functional image processing function, comprising: an image measuring unit for capturing a winder including a spindle to which a bobbin on which a material is wound is coupled, a traverse cam installed adjacent to the spindle and guiding the material to the spindle, and a contact roller installed adjacent to the spindle and applying pressure to the material when winding the material; and a controller for receiving data from the image measuring unit, analyzing the image, and controlling the operation of the winder. The controller can analyze the image data to determine at least one of the position, vibration, and speed of the spindle, the traverse cam, and the contact roller, and then individually control the operation of the spindle, the traverse cam, and the contact roller.

Description

Multifunctional Image Processing Equipped Winder Control Device The present disclosure relates to a winder control device equipped with a multi-functional image processing function capable of measuring the state of a winder using image processing technology and controlling the winder based thereon. Generally, a winder is a machine that winds continuous materials such as fibers, films, and threads, and is equipment where precise control is crucial. Conventional winder systems adopt a method of monitoring and controlling thread tension, winding speed, and position by measuring the traverse cam, contact roller, and spindle that constitute the winder through various sensors. While such sensor-based systems support the stable operation of the winder, they have several limitations. First, the use of multiple sensors increases system complexity, leading to higher installation and maintenance costs. Additionally, the placement and coordination of each sensor are challenging, and there is a possibility of errors occurring due to interactions between sensors. Second, because sensor-based systems rely on physical contact or detection at close range, sensors are susceptible to wear and damage, which can reduce system reliability. In particular, for high-speed winders, rapid sensor responsiveness is required, and this can be determined by the sensor's performance.
