Description

Technical Field

[0001] The invention relates to the technical field of yarn tube conveying, and more particularly to an automatic yarn tube feeding device for a warping system. Background Art

[0002] Warping is one of the key processes before textile weaving. Warping is the process of winding a certain number of warp yarns in parallel on a warp beam-type weaving beam according to specified length and width. Warping requires that the tension of each warp yarn is equal and evenly distributed on the warp beam or weaving beam. Warping is completed by a warping machine, which has a creel on which the yarn tube can be fixed.

[0003] Since a piece of cloth requires a lot of warp threads, the size of the creel must be large enough to have enough space to set up enough brackets for placing the yarn bobbins. When installing the yarn bobbins on the existing creel, the operator needs to move the yarn bobbins from one end of the creel to the other end, and then install the yarn bobbins on the support of the creel. This requires continuous back and forth operation, which is cumbersome and inconvenient to operate, has high labor intensity, and reduces production efficiency. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic yarn bobbin feeding device for a warping system. During the transmission process, the belt drives the yarn bobbin perpendicular to the belt to transmit synchronously. When the ball head moves to the oblique side of the tongue plate, it drives the rotating part and the yarn bobbin to rotate synchronously during the continuous movement until the yarn bobbin is arranged parallel to the belt. At this time, the servo motor is controlled to stop, and the thread ends on the yarn bobbin are passed through the corresponding wire grooves and connected to the external warping machine, thereby completing the preparation work before warping.

[0042] A yarn bobbin automatic feeding device for a warping system, specifically, comprises a frame 1 and a plurality of pay-off frames 2 slidably arranged on the frame 1; the pay-off frame 2 comprises a fixed plate 3; a belt roller 4 is symmetrically and rotatably arranged on the side surface of the fixed plate 3; a belt 5 is transmitted between the two belt rollers 4; a plurality of U-shaped seats 6 are evenly fixed on the surface of the belt 5; a rotating part 7 is rotatably arranged inside the U-shaped seat 6; the rotating part 7 comprises a connecting rod 8; a baffle 9 is fixed on the top of the connecting rod 8; a positioning rod 10 is fixed on the surface of the baffle 9; a yarn bobbin 11 is rotatably arranged on the outer peripheral side surface of the positioning rod 10; an extension rod 12 and an arc rod 13 are fixed to the peripheral side surface of the connecting rod 8 in sequence from top to bottom; a ball head 14 is fixed to the end of the extension rod 12; a tongue plate 15 adapted to the ball head 14 is fixed to the side surface of the fixed plate 3 near one end of the belt 5; a plurality of arc sleeves 16 slidably matched with the corresponding arc rods 13 are evenly fixed on the surface of the belt 5; an arc spring is fixed between the arc rod 13 and the arc sleeve 16.

[0043] Working principle of the first embodiment:

[0044] During the transmission process, the belt 5 drives the yarn tube 11 which is perpendicular to the belt 5 to transmit synchronously. When the ball head 14 moves to the oblique side of the tongue plate 15, it drives the rotating part 7 and the yarn tube 11 to rotate synchronously during the continuous movement until the yarn tube 11 is arranged parallel to the belt 5. At this time, the belt roller 4 is controlled to stop, and the thread ends on the yarn tube 11 are passed through the corresponding wire groove 58 and connected to the external warping machine to complete the preparation work before warping. The operation is simple, the work intensity is reduced, and the production efficiency is improved.

[0045] For example 2, please refer to Figure 1-12 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, the inner wall of the U-shaped seat 6 is symmetrically provided with shaft holes 17; the bottom end of the connecting rod 8 is fixed with a rotating shaft 18 that rotates with the two shaft holes 17; the tongue plate 15 is V-shaped, and is coaxially arranged with the corresponding shaft holes 17 on each U-shaped seat 6 at the top of the belt 5.

[0046] An upper ear plate 19 is fixed on the top of the fixed plate 3; a mounting plate 20 is fixed on the side of the upper ear plate 19; a ring 21 that slides with the yarn tube 11 is fixed on the side of the mounting plate 20; a semi-extension tube 22 is fixed on the side of the ring 21; a slide groove 23 is provided on the inner side of the semi-extension tube 22; a pressure plate 24 that interacts with the slide groove 23 is slidably provided on the inner side of the semi-extension tube 22; an extrusion spring 25 is fixed between the pressure plate 24 and the semi-extension tube 22.

[0047] A rotating rod 26 is rotatably provided on the side of the upper ear plate 19, and an arc plate 70 coaxial with the rotating rod 26 is fixed on its side; a feeding part 27 is rotatably provided on the rotating rod 26; a discharge port 71 is provided on the inner side of the arc plate 70; the feeding part 27 includes a rotating sleeve 28 rotatably matched with the rotating rod 26; a fixing ring 29 coaxial with the arc plate 70 is provided on the outside of the rotating sleeve 28; an avoidance groove 30 is provided on the outer side of the fixing ring 29; a semi-storage tube 31 coaxial with the sleeve 21 is fixed to the inner bottom surface of the avoidance groove 30; the yarn tube 11 is slidably arranged inside the semi-storage tube 31.

[0048] Working principle of the second embodiment:

[0049] The arc rod 13 on the rotating part 7 that is not in contact with the tongue plate 15 is tightened and stored in the corresponding arc sleeve 16 under the elastic tension of the corresponding arc spring. At this time, the corresponding positioning rod 10 is arranged perpendicular to the surface of the belt 5, and the corresponding yarn tube 11 wrapped with yarn is arranged perpendicular to the surface of the belt 5.

[0050] During the transmission process, the belt 5 drives each group of rotating parts 7 to transmit synchronously with the belt 5. When the ball head 14 on the rotating part 7 moves to fit with the oblique side surface of the tongue plate 15, the rotating part 7 continues to transmit with the belt 5, so that the ball head 14 slides along the oblique side surface of the tongue plate 15, thereby driving the rotating part 7 and the corresponding yarn tube 11 wound with yarn to rotate synchronously until the yarn tube 11 wound with yarn is parallel to the surface of the belt 5, and the belt roller 4 is controlled to stop. At this time, the corresponding groups of yarn tubes 11 wound with yarn are respectively arranged parallel to the corresponding wire grooves 58 on the yarn guide plate 57, completing the preparation work before warping.

[0051] Each group of yarn tubes 11 wound with yarn are placed into the semi-extension tube 22 one by one in turn, and the pressing plate 24 is driven to press each group of yarn tubes 11 under the elastic force of the extrusion spring 25. At this time, the semi-storage tube 31 is coaxially arranged with the ring 21. At the same time, one end of the yarn tube 11 in the semi-storage tube 31 is pressed against the inner peripheral side surface of the arc plate 70, and the yarn tube 11 adjacent to the yarn tube 11 in the semi-storage tube 31 is just tangent to the outer peripheral side surface of the fixing ring 29.

[0052] When the fixed ring 29 rotates, the yarn tube 11 therein is driven to rotate, and under the action of gravity, it falls through the discharge port 71 onto the positioning rod 10 directly below, completing the automatic loading of the yarn tube 11. During this process, the outer peripheral side of the fixed ring 29 serves to block and limit the yarn tube 11 that is just tangent to it. When the fixed ring 29 rotates in the opposite direction and resets, under the elastic action of the extrusion spring 25, the corresponding yarn tube 11 is sent into the semi-storage tube 31, thereby realizing the automatic loading of the yarn tube 11 and improving the loading efficiency of the yarn tube 11.

[0053] For example 3, please refer to Figure 1-12, the third embodiment makes the following improvements on the basis of the first embodiment. Specifically, a U-shaped rubber seat 32 is fixed to the inner bottom surface of the U-shaped seat 6; a number of elastic reset balloons 33 are evenly fixed on the surface of the belt 5; a pressure block 34 is fixed to the side surface of the connecting rod 8; a mounting cavity 35 is opened at the top of the positioning rod 10; a guide groove 36 is opened on the inner side surface of the mounting cavity 35; a piston cylinder 37 is fixed to the inner bottom surface of the mounting cavity 35; a piston rod 38 is slidably arranged inside the piston cylinder 37; a reset spring 39 is fixed between one end of the piston rod 38 and the piston cylinder 37, and a slide plate 40 slidably matched with the guide groove 36 is fixed to the other end of the piston rod 38; an air pipe 41 connected to the piston cylinder 37 is passed through the interior of the positioning rod 10; a hose is arranged between the air pipe 41 and the elastic reset balloon 33.

[0054] Working principle of the third embodiment:

[0055] During the synchronous rotation of the rotating part 7 together with the corresponding yarn tube 11 wound with yarn, the pressing block 34 gradually approaches the elastic reset balloon 33. When the yarn tube 11 and the belt 5 are arranged parallel to each other, the pressing block 34 presses the elastic reset balloon 33, and sends the air in the elastic reset balloon 33 into the piston cylinder 37 through the air supply pipe 41, thereby pushing the piston rod 38 to slide, driving the slide plate 40 to slide out of the guide groove 36, and limiting the yarn tube 11 to prevent it from detaching from the positioning rod 10 during the warping process. During this process, the reset spring 39 is stretched.

[0056] When the yarn on the bobbin 11 is unwound, the belt 5 is controlled to move so that the corresponding rotating part 7 gradually separates from the tongue plate 15. Under the elastic reset force of the arc spring, the corresponding rotating part 7 is driven to rotate and reset in the opposite direction together with the empty bobbin 11 until it is arranged perpendicular to the surface of the belt 5. The adjacent rotating part 7 together with the bobbin 11 wound with the yarn is rotated until it is arranged parallel to the surface of the belt 5. The above operation is repeated to realize automatic loading of each group of bobbins 11.

[0057] Example 4, please refer to Figure 1-12 The fourth embodiment of the present invention is improved as follows on the basis of the first embodiment. Specifically, a lower ear plate 42 is fixed to the bottom surface of the fixed plate 3; a plug plate 43 is fixed to the top of the upper ear plate 19; a slot for plugging and matching with the adjacent plug plate 43 is provided on the bottom surface of the lower ear plate 42; the frame 1 includes a support seat 44; a slide bar 45 is symmetrically fixed to the surface of the support seat 44; ear seats 46 for slidingly matching with the slide bar 45 are symmetrically fixed to the two opposite sides of the fixed plate 3; a vertical plate 47 for plugging and matching with the adjacent slot is fixed to the surface of the support seat 44; and mounting holes 48 are provided on the sides of the vertical plate 47, the plug plate 43 and the lower ear plate 42.

[0058] A driven sprocket 49 is fixed to the side surface of a belt roller 4; a servo motor 50 is installed on the surface of a support seat 44; an output end of the servo motor 50 is connected to a driving sprocket 51 through a reducer; a first chain is arranged for meshing transmission between the driving sprocket 51 and each driven sprocket 49; a support plate 53 is fixed to the surface of the support seat 44; a controller 54 is fixed to the side surface of the support plate 53; an output end of the controller 54 is electrically connected to the servo motor 50; a number of storage boxes 55 are evenly fixed on the side surface of the support plate 53 from top to bottom; a material guide channel 56 is arranged on the side of the storage box 55; a yarn guide plate 57 is evenly fixed on the side surface of the support plate 53 from top to bottom; and a wire groove 58 is evenly arranged on the side surface of the yarn guide plate 57.

[0059] A stopper 59 is fixed to the side of the fixed plate 3; a guide rod 60 is slidably provided on the side of the stopper 59; a guide ball 61 is fixed to one end of the guide rod 60; a cam 62 is fixed to the end of the belt roller 4; an L-shaped toothed plate 63 is fixed to the peripheral side of the guide rod 60; a slide rail 64 that slidably cooperates with the stopper 59 is fixed to the bottom surface of the L-shaped toothed plate 63; a limit plate 65 is fixed to the other end of the guide rod 60; a connecting spring 66 that is sleeved on the guide rod 60 is fixed between the limit plate 65 and the stopper 59; a first sprocket 67 is fixed to the end of the rotating rod 26; a fixed rod 68 is rotatably provided on the side of the fixed plate 3; a gear 69 that meshes with the L-shaped toothed plate 63 is fixed to the end of the fixed rod 68, and a second sprocket 52 is fixed to the peripheral side thereof; a second chain is provided for transmission between the first sprocket 67 and the second sprocket 52.

[0060] Working principle of the fourth embodiment:

[0061] By sliding each group of pay-off frames 2 into the slide rod 45 in turn, the slot at the bottom of the lowest pay-off frame 2 is inserted into the vertical plate 47, the plug plate 43 on the pay-off frame 2 is plugged into the slot on the adjacent pay-off frame 2, the lowest pay-off frame 2 is fixed together with the vertical plate 47 by fastening bolts, and the adjacent two pay-off frames 2 are fixedly connected by fastening bolts, thereby completing the assembly and fixation between each group of pay-off frames 2.

[0062] The servo motor 50 is controlled to start and drive the driving sprocket 51 to rotate, thereby driving the belt 5 to transmit. The distance of each cycle of the belt 5 transmission is the distance between two adjacent U-shaped seats 6. The first chain drives each group of driven sprockets 49 to rotate synchronously, thereby driving each group of belts 5 to transmit synchronously. During the rotation of the belt roller 4, the cam 62 is driven to rotate at the same time. The cam 62 rotates one circle, and under the elastic force of the connecting spring 66, the L-shaped toothed plate 63 is driven to slide back and forth along the surface of the block 59. In each cycle, the L-shaped toothed plate 63 moves back and forth to drive the gear 69 to rotate forward and reverse, thereby driving the loading part 27 to rotate 90° clockwise to unload and rotate 90° counterclockwise to reset. In summary, the servo motor 50 is controlled to start and control by the controller 54. The distance of each cycle of the belt 5 transmission is the distance between two adjacent U-shaped seats 6. During this process, the loading part 27 rotates 90° clockwise to unload and rotates 90° counterclockwise to reset.

[0063] After the yarn on the yarn tube 11 is unwound, the belt 5 is controlled to move so that the corresponding rotating part 7 gradually separates from the tongue plate 15. Under the elastic restoring force of the arc spring, the corresponding rotating part 7 is driven to rotate in the opposite direction and reset together with the empty yarn tube 11. During the transmission process of the belt 5, the yarn tube with the yarn unwound is driven through the transmission. When the transmission reaches one end of the belt 5, the empty yarn tube 11 remains parallel to the ground, and the belt 5 continues to transmit. The yarn tube 11 is tilted downward and slides into the storage box 55 through the material guide channel 56 under the action of gravity to be collected, thereby realizing automatic unloading and collection of the yarn tube 11, further improving production efficiency.
