Background

With the advancement of industrialization, especially in winding systems of chemical fiber production equipment, it is common to continuously wind the produced fiber onto an empty bobbin by a winding device. Wherein, an empty section of thick bamboo can be dismantled with the device of taking up and be connected, when the coiling work began, an empty section of thick bamboo is fixed to be set up on the device of taking up, specifically, make constantly winding cellosilk on the empty section of thick bamboo through the constantly work of taking up the device, and then make the thickness of an empty section of thick bamboo increase gradually, when the thickness of an empty section of thick bamboo reaches the thickness of finished product section of thick bamboo along with constantly winding of cellosilk (this process needs cellosilk to wind 12 hours around an empty section of thick bamboo, 24 hours or 48 hours are unequal), then the reel that will twine the cellosilk and reach finished product section of thick bamboo thickness breaks away from the device of taking up, take off the reel by the workman is manual afterwards. It should be noted that, in the process of manually taking a bobbin, the filament yarn output device in the chemical fiber production equipment still continuously outputs the filament yarn, and therefore, when manually taking a bobbin, the filament yarn at the outlet of the filament yarn output device needs to be cut off from the filament yarn on the winding drum, and then the filament yarn at the outlet of the filament yarn output device is sent to the waste yarn collecting device to be treated as waste yarn. After the bobbin is manually taken out, the empty bobbin is manually installed on the winding device, the silk yarn at the outlet of the fiber yarn output device is wound on the empty bobbin again, and the bobbin is continuously replaced manually after the empty bobbin reaches the finished bobbin, so that the continuous production of the chemical fiber production equipment is realized.

At present, a manual bobbin changing mode needs more human resources, the bobbin changing process time is long, and a great amount of waste silk waste can be generated in the process. And the property of manual tube replacement leads unskilled workers to have more tube replacement errors, and the tube replacement efficiency is low due to high error rate.
