DETAILED DESCRIPTION

[0033] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0034] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.

[0035] Example 1

[0036] Aiming at the problem that yarn bobbin loading and unloading currently relies on manual loading and unloading, which is costly and inefficient, an automatic yarn loading and unloading equipment for yarn dyeing mill is designed. Figure 1 The equipment is mainly composed of a feeding device 1, a transfer device 4, a transfer device 2, a loading and unloading device 5, and a transplanting device 3 arranged according to the yarn tube loading and unloading process. Figure 2The feeding device 1 includes a feeding platform 11, a plurality of rows of feeding troughs 12 arranged on the feeding platform 11, and a pushing mechanism 13 arranged on the feeding platform 11. The feeding trough 12 is provided with a plurality of yarn tubes. The pushing mechanism 13 can move horizontally on the feeding platform 11 and can push the yarn tubes to move in the feeding trough 12. The pushing mechanism 13 includes a pushing frame 131 which can move horizontally on the feeding platform 11, a first driving member 132 arranged on the pushing frame 131, and a pushing plate 133 arranged at the output end of the first driving member 132. The first driving member 132 can drive the pushing plate 133 to move longitudinally into the feeding trough 12. Each feeding trough 12 can be filled with yarn tubes manually or by equipment. The length of the feeding trough is equal to the length of the feeding platform 11. The pushing frame 131 can be connected to the feeding platform 11 through but not limited to the gear 84 and rack 85 mechanism. The gear 84 is driven by a motor to rotate and then cooperates with the rack 85 to drive the pushing frame 131 to move. The driving member 132 can adopt other similar driving members such as a cylinder or an oil cylinder. In this embodiment, a cylinder is preferably used. The cylinder drives the pushing plate 133 to move downward to each feeding trough 12, and drives the pushing plate 133 to push the yarn tube to the position to be clamped by the movement of the pushing frame 131. A detection column 14 with a narrow top and a wide bottom is provided at the position where the yarn tube is to be clamped on the feeding platform 11. At the same time, a sensor 15 is provided at the position of the detection column 14 on the feeding platform 11. The position of the sensor 15 is higher than the position of the detection column 14. Since the aperture sizes in the middle of the front and back sides of the yarn tube are different, the aperture of the front side is larger than the aperture of the back side, the yarn tube to be clamped can be placed on the detection column 14. If the yarn tube is placed on the back side, the yarn tube cannot be completely placed on the detection column 14, and at least a part of it is located at a position higher than the detection column 14. At the same time, this part falls into the detection range of the sensor 15. When the sensor 15 detects the yarn tube, an alarm is issued to remind the staff that the front and back sides of the yarn tube are placed incorrectly.

[0037] Reference Figure 3The transfer device 4 can preferably adopt a mechanical arm, and a plurality of three-claw air claws are arranged at the output end of the mechanical arm. The transfer device 2 includes a transfer frame 21, a transfer table 22 rotatably arranged on the transfer frame 21, and a plurality of yarn threading rods 23 arranged on the transfer table 22. The transfer device 4 can grab the yarn tubes in the feeding trough 12 to the yarn threading rods 23 for stacking; a supporting mechanism 24 is arranged on the transfer frame 21, and the supporting mechanism 24 includes a mounting plate 241 slidably connected to the transfer frame 21, and a second driving mechanism 24 arranged on the mounting plate 241. The second driving member 243 is preferably a cylinder. The mounting plate 241 can slide longitudinally on the intermediate transfer frame 21. The second driving member 243 can drive the supporting plate 242 to move back and forth horizontally. The supporting plate 242 can carry the yarn tube on the yarn threading rod 23. The three-claw air claw is driven by the mechanical arm to clamp the yarn tube on the detection column 14. The mounting plate 241 is arranged in the middle of the intermediate transfer frame 21, and is slidably connected to the intermediate transfer frame 21 through a guide rail, and is driven by the motor to drive the gear rack. The longitudinal sliding of the mounting plate 241 is realized under the action of the mechanism transmission, and the support plate 242 is inserted between the yarn threading rods 23. The yarn tube clamped by the three-claw air claw can be inserted on each yarn threading rod 23 and dragged by the drag plate 242. Each time the three-claw air claw clamps, the drag plate 242 drives the yarn tube to slowly drop the height of a yarn tube until the entire yarn threading rod 23 is inserted with the yarn tube. At this time, the drag plate 242 moves to the bottom end of the yarn threading rod 23, and then the second driving member 243 drives the drag plate 242 to move inward, so that the drag plate 242 is separated from the yarn threading rod 23 The yarn bobbin is slowly transported by the drag plate 242, thereby improving the stability of the yarn bobbin when it moves on the yarn bobbin, and preventing the yarn bobbin from sliding linearly on the yarn bobbin 23 and causing damage to the yarn bobbin.

[0038] Reference Figure 4, and then the yarn tube pile on the yarn threading rod 23 of the transfer table 22 is transferred to the yarn threading rod 23 of the yarn frame 32 through the loading and unloading device 5. The specific loading and unloading device 5 includes a driving frame 51 and a discharge mechanism 52 arranged at the driving end of the driving frame 51. The driving frame 51 can drive the discharge mechanism 52 to move freely. The discharge mechanism 52 includes a discharge frame, a centering rod 522 arranged on the discharge frame, a discharge plate 523 slidably arranged on the discharge frame, and a clamping assembly 524 arranged on the discharge plate 523. The centering rod 522 is used to insert and place the yarn tube pile, and the discharge plate 523 can drive the clamping assembly 524 to slide longitudinally on the discharge frame. When the clamping assembly 524 slides to the bottom end, it can clamp the bottom of the yarn tube pile on the yarn threading rod 23, and when it moves upward, it can drive the yarn tube pile to be inserted onto the centering rod 522; refer to Figure 6The clamping assembly 524 includes a slide seat 5241 slidably arranged on the unloading plate 523, a third driving member 5242 arranged on the unloading plate 523 and connected to the slide seat 5241 at the output end, and a sleeve group 5243 arranged on the slide seat 5241. The sleeve group 5243 includes a sleeve 52431 connected to the slide seat 5241, an outer shaft tube 52432 rotatably arranged in the sleeve 52431, an inner shaft tube 52433 sleeved in the outer shaft tube 52432, and a driving group 6 arranged on the top of the sleeve 52431. Specifically, the inner shaft tube 52433, the outer shaft tube 52432 and the sleeve 52431 can be connected by a bearing. The driving group 6 is connected with the outer shaft tube 52432 and the inner shaft tube 52433, and can drive the outer shaft tube 52432 and the inner shaft tube 52433 to rotate. The bottom ends of the outer shaft tube 52432 and the inner shaft tube 52433 are both provided with clamping arms 5244, and the two clamping arms 5244 can clamp the yarn tube; the driving frame 51 mainly adopts a large mechanical arm, which drives the unloading mechanism 52 to move freely, and drives the unloading frame to move to the top of the yarn threading rod 23 through the large mechanical arm, and then drives the unloading plate 523 to move downward through the gear 84 rack 85 mechanism, and at the same time, the clamping assembly 524 moves downward, so that the two clamping arms 5244 move to the bottom end of the yarn threading rod 23, and then through the first The three driving members 5242 drive the slide 5241 to drive the sleeve group 5243 to move toward one side of the yarn tube, and then clamp the yarn tube at the bottom through the two clamping arms 5244, and finally drive the two clamping arms 5244 to move upward through the gear 84 rack 85 structure, and then drive the yarn tube pile to move upward, so that the yarn tube pile moves to the centering rod 522, and the loading and unloading of the yarn tube pile is completed. The two clamping arms 5244 are driven to rotate and clamp through the driving group 6. The driving group 6 specifically includes a driving seat 61 slidably connected to the sleeve 52431 (specifically, a connecting portion is provided on one side of the sleeve 52431, and the driving seat 61 is slidably connected to the connecting portion), and a first connecting rod 62 connected to the top end of the outer shaft tube 52432 , a second connecting rod 63 connected to the top end of the inner shaft tube 52433, and a fourth driving member 64 connected to the driving seat 61. Two sliding grooves 65 are obliquely arranged at both ends of the driving seat 61. One end of the first connecting rod 62 and the second connecting rod 63 is located in the corresponding sliding groove 65. The output end of the fourth driving member 64 is connected to the driving seat 61. The fourth driving member 64 can drive the driving seat 61 to move, and the ends of the first connecting rod 62 and the second connecting rod 63 slide in the sliding groove 65. Since the sliding groove 65 is obliquely arranged, the first connecting rod 62 and the second connecting rod 63 drive the outer shaft tube 52432 and the inner shaft tube 52433 to rotate clockwise or counterclockwise, thereby completing the rotation, clamping or loosening of the two clamping arms.

[0039] Reference Figure 4 , Figure 5Since the yarn threading rod 23 is long and thin and is vertically fixed on the yarn frame 32, it is easy to be skewed and cause position deviation. If the deviation is large, the loading and unloading mechanism will directly insert the yarn and a malfunction will occur. Since it is impossible to determine whether the centering rod 522 corresponds to the center position of the yarn tube pile, it is necessary to perform a telescopic detection on the centering rod 522. The centering rod 522 can be designed as a telescopic rod. At the same time, a fifth driving member is provided on the unloading frame. The fifth driving member can drive the telescopic rod to be telescopic. At the same time, a floating rod 7 is provided at the bottom of the telescopic rod. At the same time, a detection sensor device is provided in the floating rod 7. When the fifth driving member drives the telescopic rod to move downward, if the floating rod 7 is resisted by the yarn threading rod 23 and moves upward, the detection sensor device is triggered, and the clamping assembly 524 continues to work, otherwise the work stops.

[0040] Reference Figure 7 A straightening device 8 is provided at the bottom of the discharge frame for straightening the threading rod 23 after it is offset. The straightening device 8 includes a straightening frame 81 provided on the driving frame 521, and a straightening seat 82 slidably provided on the straightening frame 81. The straightening seat 82 can be driven to slide longitudinally by an electric push rod. A mounting groove 83 is provided on the straightening seat 82. At the same time, two gears 84 distributed front and back are provided in the mounting groove 83, and racks 85 adapted to the gears 84 are provided on the two side walls of the mounting groove 83. The two gears 84 are respectively connected to two straightening arms 86. When the two gears 84 rotate, they can respectively drive their corresponding The straightening arm 86 rotates. Specifically, two gears are connected by a rotating shaft, one gear 84 is fixedly connected to the rotating shaft, and the other gear 84 is rotatably connected to the rotating shaft, wherein the straightening arm 86 is fixedly set on the rotating shaft, and the other straightening arm 86 is rotatably set on the rotating shaft and fixedly connected to the gear 84 rotatably connected to the rotating shaft; the two racks 85 and the two gears 84 are staggered in position, and when the straightening seat 82 moves longitudinally, the two straightening arms 86 are driven to rotate through the cooperation between the racks 85 and the gears 84, and the two straightening arms 86 rotate while clamping the yarn tube to correct the deviation of the yarn threading rod and straighten the yarn threading rod.

[0041] The yarn tube pile is transferred to the yarn threading rod 23 of the yarn rack 32 through the loading and unloading device 5, and the yarn rack 32 slides on the base frame 31 to drive the yarn tube pile to move to the specified position for dyeing, and the dyed yarn is finally transferred to the finished product box through the loading and unloading device 5 to complete the yarn dyeing.

[0042] Example 2

[0043] Reference Figure 8 , Fig. 9, since the width of the feeding trough 12 and the thickness of the yarn threading rod 23 are fixed, they cannot be applied to yarn tubes of different sizes. At the same time, when the yarn tubes are stacked on the yarn threading rod 23, the contact between the yarn tubes and the yarn threading rod 23 is not tight, resulting in the deviation of the yarn tubes. Then, when the center of gravity of the yarn tube stack is offset, the yarn threading rod 23 is also prone to deviation. Therefore, the difference between this embodiment and embodiment 1 is that adjustment devices are provided on the feeding and yarn threading rods 23. Specifically, both side walls of the feeding trough 12 are provided with clamping plates 9 whose length is compatible with the length of the feeding trough 12. The two pressure plates are connected to the side walls of the feeding trough 12 by a number of elastic members. At the same time, a number of rollers are provided on the clamping plates 9, which can be used to adjust the yarn tubes. To reduce the friction between the yarn tube and the clamping plate 9, the yarn tube is clamped by the two clamping plates 9 under the action of the elastic member, so that the loading trough 12 can adapt to yarn tubes of different sizes, and at the same time, a floating plate 10 is longitudinally arranged on the side wall of the yarn threading rod 23, and the floating plate 10 is also connected to the inside of the yarn threading rod 23 through the elastic member. At the same time, a plurality of rollers are longitudinally arranged on the outer side of the floating plate 10, and the friction between the floating plate 10 and the yarn tube is reduced by the rollers. The floating plate 10 is used to make the yarn tube in close contact with the floating rod 7 on the yarn threading rod 23 under the action of the elastic member, so that yarn tubes of different sizes will not be offset on the yarn threading rod 23, and both ends of the clamping plate 9 and the floating plate 10 are chamfered structures.

[0044] In summary, a number of yarn tubes are placed in the feeding trough 12, and under the action of the pushing plate 133, the yarn tubes in the feeding trough 12 are pushed to the position to be clamped, and then the yarn tubes are clamped to the yarn threading rod 23 on the turntable 22 for stacking through the transfer device 4, and then the turntable 22 is rotated to rotate the yarn tube stack to the position to be clamped, and then the driving frame 51 drives the clamping group to move the yarn tube stack from the yarn threading rod 23 on the turntable 22 to the yarn threading rod 23 of the yarn rack 32, and the yarn rack 32 is transported to the designated position for yarn dyeing. The entire yarn transportation and loading and unloading is automatically completed by the equipment, which has low cost and high efficiency compared to manual loading and unloading; when the yarn tube on the feeding table 11 is transferred to the yarn threading rod 23 on the turntable 22, it must first be passed through the transfer device 4 on the detection column 14, and the detection column 14 can be used to determine the positive and negative position of the yarn tube (the empty diameters in the middle of the two ends of the yarn tube are different).

[0045] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
