Description

Technical Field

[0001] The invention relates to the technical field of collective doffing devices, and in particular to a collective doffing device capable of improving efficiency. Background Art

[0002] The collective doffing device automatically removes all full bobbins from the spinning frame, replaces them with empty bobbins and starts the yarn. The existing collective doffing device uses a combination of electrical, mechanical and pneumatic methods to complete all doffing actions, including yarn pulling, tube insertion and tube delivery. Yarn pulling and tube insertion are mainly completed by the yarn holding mechanism installed on the crossbeam that runs through the entire machine. The crossbeam moves up and down and forward and backward as needed to complete the operation.

[0003] The existing collective doffing device has certain defects during use. When the collective doffing device is working, it often completes the unloading of the full-tube yarn first, and then loads the yarn tube. This causes the lifting devices such as the herringbone arm and the linear motion module to reciprocate twice or more to complete the unloading of the full-tube yarn and the loading of the yarn tube, which leads to low work efficiency. In addition, the existing collective doffing device has poor stability, and it is easy to cause the full-tube yarn and the yarn tube to fall off during the loading and unloading process, making it impossible to accurately pull out the yarn or insert the tube, and often requires manual correction or remediation, affecting work efficiency.

[0015] The beneficial effects of the present invention are: 1. When working, first insert multiple yarn tubes on the insertion rod in sequence, and transmit the yarn tubes to the bottom of the clamping mechanism through the transmission belt.

[0016] 2. Drive each clamping component in the clamping mechanism on the rear side of the I-shaped crossbeam through the cross linear module to clamp on the left and right sides of the full-cop yarn one by one, so that the clamping block and protective pad in the clamping assembly on the rear side of the I-shaped crossbeam clamp and fix the full-cop yarn; then drive the clamping mechanism on the rear side of the I-shaped crossbeam to move the full-cop yarn upward through the cross linear module, and remove the full-cop yarn from the spinning equipment; then drive the concave adjustment seat forward through the cross linear module, so that the clamping mechanism on the rear side of the I-shaped crossbeam drives the full-cop yarn forward, so that the full-cop yarn is away from the spinning equipment.

The I-shaped crossbeam drives the two clamping mechanisms thereon to rotate 180 degrees in the opposite direction, so that the positions of the two clamping mechanisms are interchanged, so that the clamping mechanism holding the full-cop yarn rotates to the rear side, and then the concave adjustment seat is driven downward to the lowest point by the herringbone arm lifting mechanism; at this time, the clamping mechanism on the I-shaped crossbeam drives the full-cop yarn to be inserted into the insertion rod of the inner conveyor belt; the clamping blocks and protective pads in the clamping components release the clamping and fixing of the full-cop yarn; then the clamping mechanism is moved to the top of the full-cop yarn without affecting the conveyor belt to drive the full-cop yarn to move, thereby completing the yarn dropping operation; the operation process is highly stable, and the herringbone arm lifting mechanism only needs one lifting operation to complete operations such as yarn pulling and tube insertion, and the yarn tube and full-cop yarn can be accurately clamped, transported and plugged during the working process, which greatly improves the work efficiency.

[0029] See also Figure 2 , Figures 4 to 6 One end of the circular shaft 51 away from the I-shaped crossbeam 5 passes through the side wall of the concave adjustment seat 4 and is fixedly connected to the limiting ring 52. The limiting ring 52 is rotatably connected to the side plate of the concave adjustment seat 4. Two locking grooves 54 are symmetrically provided on the side of the circular block 53.

[0030] The I-shaped crossbeam 5 is rotatably connected to the concave adjustment seat 4 through two circular shafts 51 at its two ends. When the circular shaft 51 rotates, it drives the limit ring 52 to rotate along the outer side of the concave adjustment seat 4, thereby limiting the circular shaft 51, so that the I-shaped crossbeam 5 and the circular shaft 51 can only rotate along the concave adjustment seat 4.

[0031] The locking mechanism includes a second telescopic cylinder 6 and a guide seat 63 fixedly mounted on the side of the concave adjustment seat 4.

[0032] The locking groove 54 formed on the side of the circular block 53 is a V-shaped groove, and the lower end of the locking block 61 is a V-shaped end portion matching the V-shaped groove.

[0033] The locking block 61 is driven to move up and down by the extension and retraction of the piston rod of the second telescopic cylinder 6, and the guide groove 62 on the side of the locking block 61 slides up and down along the guide seat 63, so that the locking block 61 can move up and down stably; When the piston rod of the second telescopic cylinder 6 contracts upward, the end of the locking block 61 is separated from the locking groove 54, and the circular block 53 can rotate along with the circular shaft 51; When the piston rod of the second telescopic cylinder 6 extends downward, the end of the locking block 61 engages with the locking groove 54, thereby locking the circular block 53 and preventing the circular block 53 from rotating, thereby preventing the circular shaft 51 and the I-shaped beam 5 from rotating.

[0034] See also Figure 4 , Figures 6 to 8 The clamping mechanism includes a light rod 55 and a regular polygonal rod 56 installed on one side of the I-shaped crossbeam 5. The two ends of the light rod 55 are respectively fixedly connected to the two inner side walls of the I-shaped crossbeam 5. The regular polygonal rod 56 is rotatably connected to the I-shaped crossbeam 5. The regular polygonal rod 56 is driven by the motor shaft of a servo motor fixedly installed on the side of the I-shaped crossbeam 5. Multiple groups of clamping components are equidistantly installed on the regular polygonal rod 56.

[0035] Each time the I-shaped crossbeam 5 rotates half a circle, it drives the two clamping mechanisms thereon to rotate 180 degrees, thereby exchanging the positions of the two clamping mechanisms.

[0036] The clamping assembly includes a bidirectional transmission stud 7 which is sleeved on a regular polygonal rod 56. A regular polygonal groove 71 is formed on the side of the bidirectional transmission stud 7. The regular polygonal rod 56 is inserted into the regular polygonal groove 71. The bidirectional transmission stud 7 is fixedly connected to the regular polygonal rod 56. Movable plates 72 are symmetrically sleeved on the bidirectional transmission stud 7. A sliding sleeve 73 is fixedly installed on one end of the two movable plates 72. A transmission seat 74 is fixedly connected to the other end of the two movable plates 72. Clamping blocks 8 are installed on the sides of the two transmission seats 74 that are close to each other.

[0037] The distance between the clamping components is the same as the distance between the insertion rods 15 on the conveyor belt 14 . When working, each clamping component corresponds to one insertion rod 15 , that is, the clamping component is located above the insertion rod 15 .

[0038] The movable plate 72 is threadedly connected to the bidirectional transmission stud 7, the sliding sleeve 73 is slidably connected to the polished rod 55 left and right, and the two clamping blocks 8 are symmetrically distributed left and right.

[0039] The motor shaft of the servo motor drives the regular polygonal rod 56 to rotate, and the regular polygonal rod 56 drives the multiple bidirectional transmission studs 7 thereon to rotate synchronously, and the bidirectional transmission studs 7 drive the two movable plates 72 thereon to move closer to each other, and the movable plate 72 drives the sliding sleeve 73 and the transmission seat 74 to move synchronously. At this time, the sliding sleeve 73 slides along the light rod 55, so that the movable plate 72 can stably drive the transmission seat 74 to move, and the clamping block 8 is driven to move through the transmission seat 74, so as to clamp the yarn tube and the full tube yarn; The motor shaft of the servo motor drives the regular polygonal rod 56 to reverse, so that the two-way transmission stud 7 drives the two movable plates 72 thereon to move away from each other, the two movable plates 72 drive the two transmission seats 74 away from each other, and the two transmission seats 74 drive the two clamping blocks 8 away from each other, thereby loosening the clamping of the yarn tube and the full tube yarn.

[0040] A contraction groove 75 is provided on one side of the transmission seat 74, and sliding grooves 76 are provided on the front and rear side walls of the contraction groove 75. The clamping block 8 is slidably connected to the contraction groove 75 left and right. The two clamping blocks 8 are fixedly connected to a protective pad 81 on the side close to each other. The clamping surface of the protective pad 81 is provided with anti-slip grooves. The protective pad 81 is provided to prevent the clamping force from being too large to damage the yarn tube and the full tube yarn. The anti-slip grooves can effectively prevent the yarn tube and the full tube yarn from slipping during movement. An elastic sheet 83 is equidistantly fixedly installed on the side of the clamping block 8 away from the protective pad 81, and the other side of the elastic sheet 83 abuts against the inner side of the contraction groove 75. The front and rear sides of the clamping block 8 are fixedly connected with a slider 82, and the slider 82 is slidably connected to the slide groove 76 left and right.

[0041] When the clamping block 8 clamps and fixes the yarn bobbin and the full-cop yarn, the protective pad 81 on the side of the clamping block 8 first contacts the yarn bobbin and the full-cop yarn, and the anti-slip pattern provided on the side of the protective pad 81 prevents the yarn bobbin and the full-cop yarn from falling off; When the clamping force is too large, the protection pad 81 is deformed first, and at the same time, the clamping block 8 shrinks into the shrinkage groove 75 on the side of the transmission seat 74, and the clamping block 8 squeezes the elastic sheet 83, thereby achieving buffer protection. With the cooperation of the protection pad 81 and the elastic sheet 83, it can effectively prevent the clamping force from being too large to cause damage to the yarn tube or full tube yarn.

[0042] Working principle: When working, first insert multiple yarn tubes on the insertion rod 15 in sequence, and transmit the yarn tubes to the bottom of the clamping mechanism through the transmission belt 14. At this time, the concave adjustment seat 4 is driven forward by the cross linear module 33, so that the multiple clamping components in the clamping mechanism on the front side of the I-shaped cross beam 5 are respectively located directly above the multiple yarn tubes, and then the concave adjustment seat 4 is driven downward by the cross linear module 33, so that the clamping mechanism moves downward, so that the two clamping blocks 8 in the clamping components move to the left and right sides of the yarn tube; The motor shaft of the servo motor at the front end of the side of the I-shaped crossbeam 5 drives the regular polygonal rod 56 to rotate, and the regular polygonal rod 56 drives multiple bidirectional transmission studs 7 thereon to rotate synchronously, and the bidirectional transmission studs 7 drive the two movable plates 72 thereon to move closer to each other, and the movable plate 72 drives the clamping block 8 to move through the transmission seat 74, and the clamping block 8 drives the protective pad 81 to clamp and fix the yarn tube.

[0043] The piston rod of the first telescopic cylinder 25 extends to drive the convex slide 24 to slide along the convex groove 11, and the convex slide 24 drives the auxiliary rotating arm 23 to rotate, and the auxiliary rotating arm 23 drives the main rotating arm 21 to rotate upward, and the main rotating arm 21 drives the concave lifting frame 3 to move upward to the highest point through the upper rotating seat 22, and the concave lifting frame 3 drives the concave adjusting seat 4 to move upward to the highest point through the cross linear module 33, and the I-shaped crossbeam 5 drives the yarn tube to move upward through the clamping mechanism; The I-shaped crossbeam 5 drives the clamping mechanism on the rear side to move to the side of the full-cop yarn, and drives the concave adjustment seat 4 to move backward through the cross linear module 33, so that each clamping component in the clamping mechanism on the rear side of the I-shaped crossbeam 5 is clamped on the left and right sides of the full-cop yarn one by one, and the clamping component does not contact the full-cop yarn at this time; then the motor shaft of the servo motor at the rear end of the side of the I-shaped crossbeam 5 drives the regular polygonal rod 56, so that the two movable plates 72 in the clamping component move closer to each other, so that the clamping block 8 drives the protection pad 81 to approach the full-cop yarn, and the full-cop yarn is clamped and fixed by the cooperation of the two clamping blocks 8 and the two protection pads 81; After the full bobbin is clamped, the concave adjustment seat 4 is driven to move upward by the cross linear module 33, so that the clamping mechanism on the rear side of the I-shaped cross beam 5 drives the full bobbin to move upward, and the full bobbin is removed from the spinning equipment. Then, the concave adjustment seat 4 is driven to move forward by the cross linear module 33, so that the clamping mechanism on the rear side of the I-shaped cross beam 5 drives the full bobbin to move forward, and the full bobbin is away from the spinning equipment. At this time, the piston rod of the second telescopic cylinder 6 is retracted upward, so that the end of the locking block 61 is separated from the locking groove 54, and the circular block 53 can rotate with the circular shaft 51; The output shaft of the stepper motor drives the circular shaft 51 to rotate half a circle, the circular shaft 51 drives the I-shaped crossbeam 5 to rotate half a circle, and the I-shaped crossbeam 5 drives the two clamping mechanisms thereon to rotate 180 degrees, so that the positions of the two clamping mechanisms are interchanged, thereby interchangeing the positions of the yarn tube and the full tube yarn.

[0044] After the position conversion is completed, the piston rod of the second telescopic cylinder 6 is extended downward, so that the end of the locking block 61 is engaged with the locking groove 54, thereby locking the circular block 53, so that the circular shaft 51 and the I-shaped crossbeam 5 cannot rotate, and the I-shaped crossbeam 5 and the clamping mechanism will not shake when moving up and down and forward and backward, ensuring the stable delivery, insertion and yarn pulling.

[0045] The concave adjustment seat 4 is driven to move backward through the cross linear module 33, and the I-shaped cross beam 5 drives the yarn tube to move backward through the clamping mechanism, so that the yarn tube moves to the top of the winding rod of the spinning equipment, and then the concave adjustment seat 4 is driven to move downward through the cross linear module 33, so that the yarn tube is sleeved on the winding rod; at this time, the motor shaft of the servo motor at the rear end of the side of the I-shaped cross beam 5 drives the regular polygonal rod 56 to rotate in the opposite direction, so that the two movable plates 72 in the clamping component move away from each other, so that the clamping block 8 and the protective pad 81 release the clamping fixation on the yarn tube, and then the concave adjustment seat 4 is driven to move forward through the cross linear module 33, thereby completing the tube feeding and insertion operations.

[0046] At this time, the piston rod of the second telescopic cylinder 6 is retracted upward, and the end of the locking block 61 is separated from the locking groove 54. The output shaft of the stepping motor drives the circular shaft 51 to rotate in the opposite direction by half a circle, and the circular shaft 51 drives the I-shaped crossbeam 5 to rotate in the opposite direction by half a circle. The I-shaped crossbeam 5 drives the two clamping mechanisms thereon to rotate 180 degrees in the opposite direction, so that the positions of the two clamping mechanisms are interchanged, so that the clamping mechanism holding the full tube yarn is rotated to the rear side, and then the piston rod of the second telescopic cylinder 6 is extended downward, so that the end of the locking block 61 is engaged with the locking groove 54, thereby locking the circular block 53.

[0047] The piston rod of the first telescopic cylinder 25 contracts, so that the convex slide 24 drives the auxiliary rotating arm 23 to rotate, and the auxiliary rotating arm 23 drives the main rotating arm 21 to rotate downward, and the main rotating arm 21 drives the concave lifting frame 3 to move downward to the lowest point through the upper rotating seat 22, and the concave lifting frame 3 drives the concave adjusting seat 4 to move downward to the lowest point through the cross linear module 33; at this time, the clamping mechanism on the I-shaped crossbeam 5 drives the full bobbin to be inserted into the insertion rod 15 of the inner conveyor belt 14; Then, the motor shaft of the servo motor at the rear end of the side of the I-shaped crossbeam 5 drives the regular polygonal rod 56 to rotate in the opposite direction, so that the two movable plates 72 in the clamping component move away from each other, so that the clamping block 8 and the protection pad 81 release the clamping fixation of the full-cop yarn; then, the concave adjustment seat 4 is driven to move upward through the cross linear module 33, so that the clamping mechanism moves to the top of the full-cop yarn without affecting the movement of the full-cop yarn driven by the conveyor belt 14, thereby completing the yarn dropping operation.

[0048] The operation process is highly stable, and the herringbone arm lifting mechanism only needs one lifting operation to complete operations such as yarn pulling and tube insertion. In addition, the yarn tubes and full tube yarns can be accurately clamped, transported, inserted and pulled out during the working process, which greatly improves the work efficiency.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
