[0020] like Figures 1 to 3 As shown, a yarn changing manipulator for a roving machine includes a yarn taking component 1, a rotating component 2, a lifting component 3, a telescopic component 4 and a bracket 5; the lifting component 3 is connected below the rotating component 2, and the rotating component 2 realizes the rotation of the lifting component 3; the telescopic component 4 is connected below the lifting component 3, and the lifting component 3 realizes the up and down movement of the telescopic component 4, and the yarn taking component 1 is slidably connected to the telescopic component 4, and the telescopic component 4 realizes the left and right movement of the yarn taking component 1; the yarn taking component 1 is used to take off the yarn tube. The yarn taking component 1 first extends to the left and right sides under the drive of the telescopic component 4, and then moves upward under the drive of the lifting component 3, so that both the empty yarn tube and the full yarn tube fall on the yarn taking component 1. After taking off the empty yarn tube and the full yarn tube, the lifting component 3 drives the yarn taking component 1 to move downward, and the telescopic component 4 drives the yarn taking component 1 to move inward, so as to reduce the space occupied by the empty yarn tube and the full yarn tube when rotating and exchanging, increase the rotation speed of the rotating component 2, and improve the production efficiency.

[0021] There are two groups of yarn taking components 1, and the yarn taking components 1 are respectively located on both sides of the telescopic component 4; each group of yarn taking components 1 includes a yarn receiving seat 11 and a connecting plate 12, the yarn receiving seat 11 is fixed on the connecting plate 12, and the connecting plate 12 is connected to the telescopic component 4 through a first sliding component. There are two sets of the first sliding components, and each set of the first sliding components is respectively connected to a group of yarn taking components 1; each set of the first sliding components includes a first slider 13 and a first slide rail 14, the first slide rail 14 is connected to the telescopic component 4 through a fixed frame 15, the connecting plate 12 is connected to the first slider 13, and the first slider 13 is adapted to the first slide rail 14. The telescopic component 4 includes two telescopic cylinders 16, which are fixed to the bottom of the fixed frame 15 through a fixed seat 17, and the telescopic directions of the two telescopic cylinders 16 are opposite to each other; each telescopic cylinder 16 is connected to the first slider 13 through a connector 18. When the telescopic cylinder 16 is extended, the telescopic cylinder 16 drives the first slider 13 to move outward through the connecting piece 18, and the first slider 13 slides on the first slide rail 14, which improves the smoothness of the movement. The connecting plate 12 connected to the first slider 13 moves outward following the first slider 13, and the connecting plate 12 drives the yarn receiving seat 11 to move outward until the distance between the two yarn receiving seats 11 is roughly equal to the distance between the empty yarn tube and the full yarn tube. When the telescopic cylinder 16 is retracted, the telescopic cylinder 16 moves the first slider 13 inward, and finally moves the yarn receiving seat 11 that has taken the empty yarn tube and the full yarn tube inward, reducing the occupied space and maintaining the stability of the work.

[0022] The lifting assembly 3 includes a lifting cylinder 21, an upper fixed plate 22 and a lower fixed plate 23. The upper fixed plate 22 and the lower fixed plate 23 are respectively connected to the rotating assembly 2. The lifting cylinder 21 is fixed to the upper fixed plate 22. The telescopic end of the lifting cylinder 21 is connected to the fixed frame 15. The upper fixed plate 22 is connected to the lower fixed plate 23 through a second sliding assembly. The fixed frame 15 is connected to the second sliding assembly. The second sliding assembly includes a second slider 24 and a second guide rail 25. The second guide rail 25 is connected between the upper fixed plate 22 and the lower fixed plate 23. The fixed frame 15 is connected to the second slider 24. The second slider 24 is adapted to the second guide rail 25. When the lifting cylinder 21 contracts, the lifting cylinder 21 will move the yarn receiving seat 11 upward through the fixed frame 15. The yarn receiving seat 11 abuts against the bottom of the empty yarn tube and the full yarn tube, and the empty yarn tube and the full yarn tube are removed. When the lifting cylinder 21 extends, the lifting cylinder 21 moves the yarn receiving seat 11 downward through the fixing frame 15, and the fixing frame 15 slides on the second guide rail 25 through the second slider 24, so that the movement of the fixing frame 15 is more stable and smooth. After the yarn receiving seat 11 receives the empty yarn tube and the full yarn tube, the yarn receiving seat 11 moves downward under the action of the fixing frame 15, so that the empty yarn tube and the full yarn tube completely fall on the yarn receiving seat 11.

[0023] The rotating assembly 2 includes a rotating cylinder 31, an upper rotating shaft 32 and a lower rotating shaft 33. The upper rotating shaft 32 is connected to the rotating end of the rotating cylinder 31 through an upper rotating member.

After the empty bobbin and the full bobbin fall on the yarn receiving seat 11, the rotating cylinder 31 is started, so that the upper rotating shaft 32 and the lower rotating shaft 33 rotate synchronously in the bearings respectively, and finally the yarn receiving seats 11 on both sides are rotated 180° to exchange positions.

[0024] The upper rotating member is fixed to the upper part of the bracket 5 by the first fixing member 41, and the lower rotating member is fixed to the lower part of the bracket 5 by the second fixing member 42. The bracket 5 can determine the installation position of the yarn changing robot.

[0025] Workflow:

[0026] First, the telescopic cylinder 16 extends outward, and the telescopic cylinder 16 drives the first slider 13 to move outward through the connecting piece 18. The first slider 13 slides on the first slide rail 14, which improves the smoothness of the movement. The connecting plate 12 connected to the first slider 13 moves outward following the first slider 13, and the connecting plate 12 drives the yarn receiving seat 11 to move outward until the distance between the two yarn receiving seats 11 is roughly equal to the distance between the empty yarn tube and the full yarn tube. When the lifting cylinder 21 contracts, the lifting cylinder 21 will move the yarn receiving seat 11 upward through the fixed frame 15, and the yarn receiving seat 11 abuts against the bottom of the empty yarn tube and the full yarn tube. After the yarn receiving seat 11 receives the empty yarn tube and the full yarn tube, the lifting cylinder 21 extends, and the lifting cylinder 21 moves the yarn receiving seat 11 downward through the fixed frame 15 until the empty yarn tube and the full yarn tube are completely placed on the yarn receiving seat 11, and then stops descending. The telescopic cylinder 16 contracts, and the telescopic cylinder 16 moves the first slider 13 inward, and finally moves the yarn receiving seat 11 that has taken the empty bobbin and the full bobbin inward. After the telescopic cylinder 16 stops moving, the rotary cylinder 31 starts, and the upper rotary shaft 32 and the lower rotary shaft 33 rotate synchronously in the bearings, and finally the yarn receiving tubes on both sides rotate 180 degrees to exchange positions, thus completing an exchange of empty and full bobbin.
