Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a yarn storage device for yarn packages. Background Technology

[0002] The yarn dyeing process involves unwinding the raw yarn on a winding machine, passing it through a yarn tensioning device to remove impurities and cotton knots from the yarn surface, and winding it into loosely shaped cones with the required density, shape, and size under a certain tension. The cones are then arranged for subsequent dyeing. Multiple arranged cones are strung together and then picked up and placed into the dyeing area by a robotic arm.

[0003] For example, a yarn package quick sorting and storage device with authorization announcement number CN212531743U includes a fixed base, a turntable shafted above the base, and a drive device for rotating the turntable. At least two yarn storage rods are fixedly connected to the turntable and distributed circumferentially along its center. The yarn storage rods are vertically arranged. However, this document still has shortcomings. In use, the yarn packages are arranged sequentially by placing them on the yarn storage rods. The drive device rotates the turntable, rotating the different yarn storage rods below a guide device. Then, a robotic arm removes the yarn packages from the storage rods. A speed reduction device controls the yarn packages falling from the storage rods. The device aims to reduce the impact of falling yarn packages and protect the yarn and equipment. However, the aforementioned document describes a pneumatic indexing plate that drives a turntable to rotate the yarn storage rod. This requires the storage rod to rotate 90 degrees each time and not continue moving due to inertia. In practice, this makes it difficult to accurately rotate the storage rod to the desired position. Furthermore, the storage rod is positioned below the yarn guide device during operation. The document specifies a fixed height for the storage rod, limiting its position to below the guide device at a fixed height. This makes it difficult to adjust the height of the storage rod according to actual usage requirements. Utility Model Content

[0031] Working principle:

[0032] When using a yarn storage device to store and insert yarn during yarn package processing;

[0033] The height adjustment stage of the yarn storage rod:

[0034] When the height of the yarn storage rod 8 needs to be adjusted according to the height of the guide device for the falling yarn, turn the handle 402. The handle 402 drives the rotating rod 401 to rotate, the rotating rod 401 drives the two first bevel gears 403 to rotate, the first bevel gears 403 drive the second bevel gear 404 to rotate, the second bevel gear 404 drives the screw 405 to rotate, the screw 405 drives the threaded block 406 to move, the threaded block 406 drives the first bracket 407 to move, the second bracket 5 slides on the outer wall of the first bracket 407, the second bracket 5 moves together with the frame 2, the height of the frame 2 changes, and thus the height of the yarn storage rod 8 changes.

[0035] Yarn storage stage:

[0036] The moving device positions one of the yarn storage rods 8 below the guide device for the falling yarn packages. The yarn packages fall sequentially and are placed onto the yarn storage rod 8. As the yarn packages fall onto the outer wall of the yarn storage rod 8, they contact the roller 11. The roller 11 drives the third support 10 to move, which in turn drives the sliding rod 13 to move. The sliding rod 13 slides inside the sleeve 12 and compresses the spring 14. The spring 14 buffers the force, slowing down the falling yarn packages and reducing the impact. Once the yarn storage rod 8 is full, the motor 301 is started. The motor 301 drives the first rotating rod 302 to rotate, which in turn drives the first disc 303 to rotate. The first disc 303 drives the protrusion 304 and the pin 305 to rotate. The pin 305 then moves... The pin 305 moves into the groove 306 and drives the groove wheel 308 to rotate. When the pin 305 moves out of the groove 306, the groove wheel 308 rotates exactly 90 degrees. At this time, the outer wall of the protrusion 304 is inside the groove 307, preventing the groove wheel 308 from rotating under inertia. When the groove wheel 308 rotates, it drives the second rotating rod 6 to rotate. The second rotating rod 6 drives the second disc 7 to rotate. The second disc 7 drives the yarn storage rod 8 to rotate, rotating the other yarn storage rod 8 to below the guide device. The motor 301 is turned off. The yarn storage rod 8 rotates 90 degrees each time and will not continue to move under inertia. In use, it is easy to make the yarn storage rod 8 rotate accurately to the required position. Then, the bobbin yarn on the yarn storage rod 8 is taken away by the robot arm.
