Description

Dancer device using magnetic force}

The present invention relates to a denser device that adjusts tension using magnetic force. More specifically, a denser roll that uses magnetic force as tension rotates around a film supply roll driven by a speed control motor and simultaneously performs a pendulum motion in an orbit. This relates to a denser device using magnetic force that allows the tension of the film to be adjusted while doing so.

In industry, devices that continuously supply and manufacture film or implement functions are often used to improve productivity. It is used in a variety of fields, including the printed electronics industry, secondary battery manufacturing, ITO film coating manufacturing, laminators for stacking films, OLED manufacturing processes, and packaging film manufacturing processes.

In the field of manufacturing products using film, a buffer device for film supply and a device that maintains a constant tension are required due to differences in actual usage speed between the supply unit that supplies the film and the actual work area and the expansion and contraction of the film. A device with this function is called a denser device.

The importance of these densor devices varies depending on the purpose of use. In places where simple buffering functions are performed, a method of adjusting the usage variation and maintaining tension by winding the film on a roller that moves up and down by gravity due to the weight of the roller was used. , problems have been discovered due to mechanical problems caused by tilting and shaking of the film or speeding up, so more precise devices are being developed, and methods using springs, speed control motors, and pneumatic pressure have been developed and used. , As the film industry's manufacturing process becomes increasingly thinner and more precise and faster, problems such as the responsiveness of the sensor, automation possibilities, and fine adjustment of tension remain.

In addition, the conventional denser device requires the expansion of a number of devices such as a torque motor and a tension variable control means that provides a driving signal to the torque motor, and requires the addition of a large number of devices for fine adjustment of the operating speed and tension of the machine. Due to difficulties, significant improvements to existing denser devices are required.
