Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and in particular relates to a drop tube manipulator for changing yarn frames of a ribbon loom. Background Art

[0002] The creel in a ribbon loom is a crucial component for supporting and supplying the yarn required for ribbon production. The creel's function is to ensure a steady supply of yarn during the loom's operation, thereby ensuring both quality and efficient production. The creel typically consists of multiple yarn reels and a supporting structure. Each reel holds a different color or type of yarn for use during the loom's production process. During the ribbon production process, it is often necessary to switch between different yarns or replace used reels.

[0003] At present, when replacing the yarn bobbins on the creel of a ribbon loom, a robotic arm is mostly used to remove the empty yarn tubes. Only one group can be removed at a time, and the empty tubes need to be discharged into a recycling box. The entire operation process is very cumbersome. The number of empty tubes stored in the creel is in groups, and the number is large, which cannot meet the needs of efficient production. For this reason, we provide a robotic arm for removing empty tubes from the creel of a ribbon loom to solve the above problems. Summary of the Invention

[0038] Example 3

[0039] See also Figure 1-8 On the basis of Example 1, a collecting box 26 is provided on one side of the bracket 21, and the surface of the driving roller 23 is movably connected to the inner wall of the bracket 21 through a bearing.

When the empty yarn bobbin falls on the top of the conveyor belt 24, automatic transportation can be achieved. The collecting box 26 is used to store the empty yarn bobbins to facilitate subsequent processing. The first magnet 28 and the second magnet 29 have opposite magnetic poles. When the first magnet 28 approaches the second magnet 29, the moving column 12 can be driven to move. The spring 30 has the function of compressing energy storage, and the moving column 12 can be reset when the first magnet 28 is separated from the second magnet 29.

[0041] The working principle of the present invention is as follows: the staff starts the hydraulic rod 3 through the external controller, and the hydraulic rod 3 cooperates with the movable plate 4 to drive the clamping plate 5 to move to the surface of the empty yarn tube. When the movable plate 4 moves, it drives the second magnet 29 to insert into the support rod 2. Under the adsorption action of the magnet, it can drive the first magnet 28 to move. The first magnet 28 cooperates with the movable column 12 to drive the inclined rod 13 to move, and the inclined rod 13 drives the limit block 14 to retract into the support rod 2, canceling the limit on the empty yarn tube, and then starts the electric push rod 6.

[0042] After that, the driving motor 9 is started, and the driving motor 9 cooperates with the driving box 8 to drive the supporting plate 7 and the clamping plate 5 to rotate, so that the empty yarn bobbin rotates downward, and the servo motor 17 is started at the same time. The servo motor 17 cooperates with the screw 18 to drive the movable sleeve 19 to move, and the movable sleeve 19 cooperates with the support plate 7 to drive the empty yarn bobbin to fall into the guide shell 10. Then, the electric push rod 6 is controlled to drive the two sets of clamping plates 5 to move in opposite directions, cancel the fixation of the empty yarn bobbin, and make the empty yarn bobbin fall into the guide shell 10. The inclined design of the guide shell 10 can be used to transport the empty yarn bobbin to the top of the conveyor belt 24. When the empty yarn bobbin falls on the top of the conveyor belt 24, the rotating motor 22 can be started, and the rotating motor 22 drives the driving roller 23 to rotate. The driving roller 23 cooperates with the auxiliary roller 25 and the conveyor belt 24 to transport the empty yarn bobbin, and transports the empty yarn bobbin to the collecting box 26 for collection, thereby realizing the function of automatic collection, which can effectively improve the collection efficiency of the empty yarn bobbin.
