Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to an intelligent sensing lever device for an automatic drop-coil trolley. Background Technology

[0002] Winding machines are commonly used equipment in the ring spinning industry. A winding machine can wind multiple small tubes of yarn onto a paper tube to form a large bobbin. When the bobbin length is wound into a large bobbin as required, after winding, the bobbin needs to be removed, a new paper tube is installed, and winding continues. In order to reduce the labor intensity of workers, a matching automatic yarn carriage needs to be installed on the winding machine. The automatic yarn carriage completes the process of unloading the bobbin and loading a new paper tube. The process of the automatic yarn carriage unloading the bobbin is as follows: the yarn carriage first lowers to the winding machine handle through a lever mechanism. After contacting and sensing the winding machine handle, it stops. The lever mechanism then opens the winding machine handle and raises it to unload the bobbin.

[0003] Because the diameter of the yarn wound on the winding machine varies each time the winding machine winds, depending on the yarn count requirements of the winding process, the position of the winding machine handle is uncertain. As a result, the position of the lever mechanism to find the winding machine handle is uncertain each time it descends. Therefore, a speedometer device is needed to sense the position of the winding machine handle.

[0004] Existing automatic yarn storage carts for winding machines generally use a configuration of one lever and one code meter. Each lever needs to be independently equipped with a code disk and photoelectric sensor to detect whether it is in contact with the yarn support. When multiple sets of levers are connected in parallel and operate simultaneously, the number of code meters increases exponentially with the number of levers, which not only takes up space and increases costs, but also causes complicated wiring and difficulty in signal aggregation, making it difficult to achieve the integrated detection requirements of compact structure and easy maintenance.

[0005] Therefore, an intelligent sensing lever device for an automatic dropper trolley is proposed to solve the above problems. Summary of the Invention

[0012] In the above technical solution, the adjusting mechanism further includes an electric telescopic cylinder, and a pair of electric telescopic cylinders are provided. A fixed frame is fixedly connected to the front side of the limiting plate. The electric telescopic cylinders are respectively fixedly connected to the upper and lower sides of the fixed frame. The front sides of the upper and lower cylinders extend to the rear side of the fixed frame. An annular groove is opened on the front side of both the upper and lower cylinders.

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0023] In actual use, it was found that the diameter of the winding bobbin varies each time the winding machine winds the yarn, depending on the yarn count requirements of the winding process. This causes the position of the winding machine handle 7 to be uncertain, which in turn makes it uncertain when the lever mechanism descends to find the position of the winding machine handle 7. The existing method of adding a force sensor to the lever mechanism to sense the handle of the winding machine is costly and has a high failure rate after long-term use. To solve the above problems, the following structure is invented.

[0024] like Figures 1-13 The automatic unwinding trolley intelligent sensing lever device shown includes a yarn storage trolley frame 1, a winding machine handle 7, a transmission mechanism, a lever mechanism, and a code disk positioning mechanism; The transmission mechanism includes a drive motor 2, a gearbox 3, a drive sprocket 4, and a driven sprocket 5. The drive motor 2 is fixedly connected to the rear side of the yarn storage cart frame 1, the gearbox 3 is fixedly connected to the front side of the yarn storage cart frame 1, and the driven sprocket 5 is rotatably connected to the front side of the yarn storage cart frame 1. The lever mechanism includes a cylinder 8 and a lever 9. A pair of cylinders 8 and levers 9 are provided. The cylinder 8 is located on the rear side of the yarn storage cart frame 1. The lever 9 is fixedly connected to the output end of the cylinder 8. An upper cylinder 10 is rotatably connected through the yarn storage cart frame 1. A lower cylinder 15 is rotatably connected inside the upper cylinder 10. The code disk positioning mechanism includes a code disk 12, a photoelectric U-shaped through-beam sensor 14, a driven sprocket 5 rotatably connected to a limit disk 11, a code disk 12 fixedly connected to the front side of the limit disk 11, a number of through holes 13 are equidistantly opened on the side wall of the code disk 12, the photoelectric U-shaped through-beam sensor 14 is set on the code disk 12, and the limit disk 11 is provided with an adjustment mechanism for controlling the drive of the lever 9; The drive sprocket 4 is fixedly connected to the output end of the front side of the gearbox 3. The output end of the drive motor 2 passes through the yarn storage cart frame 1 and is fixedly connected to the other output end of the gearbox 3. A chain 6 is connected between the drive sprocket 4 and the driven sprocket 5. A torque return spring 16 is fixedly connected between the rear side of the limit plate 11 and the inner side of the driven sprocket 5. A bracket 17 is fixedly connected to the front side of the yarn warehouse frame 1. A photoelectric U-shaped through-beam sensor 14 is fixedly connected to the rear side of the bracket 17. An arc-shaped groove 18 is provided through the front side of the limiting plate 11, and a push rod 19 is fixedly connected to the inner side of the driven sprocket 5 relative to the inner side of the arc-shaped groove 18. All cylinders 8 have through holes 20 on their side walls. The upper cylinder 10 is fixedly connected to the hole 20 on one of the cylinders 8. A support seat 21 is fixedly connected to the rear side of the yarn storage cart frame 1. An upper rotating seat 22 is fixedly connected to the top of the support seat 21. The lower cylinder 15 is rotatably connected to the inner side of the rotating seat 22, and the rear end of the lower cylinder 15 is fixedly connected to the hole 20 on another cylinder 8. An upper electromagnet 23 is fixedly connected to the rear side of the yarn storage cart frame 1 relative to the position above the upper cylinder 10. A lower electromagnet 24 is fixedly connected to the top of the rotating seat 22. Both the upper cylinder 10 and the lower cylinder 15 are made of iron. When the yarn cart moves to the winder handle 7, the drive motor 2 starts the drive gearbox 3 to rotate, which in turn drives the drive sprocket 4 mounted on the gearbox 3 to rotate. This, in turn, drives the driven sprocket 5 to rotate simultaneously under the transmission of the chain 6. Since a torque return spring 16 is installed between the driven sprocket 5 and the limiting plate 11, and a push rod 19 is installed on the side of the driven sprocket 5, and an arc-shaped groove 18 is opened on the limiting plate 11, the push rod 19 can move along the arc shape within the arc-shaped groove 18 (and at this time, the control adjustment mechanism connects the limiting plate 11 to the upper cylinder 10, so that the rotation of the limiting plate 11 can drive the upper cylinder 10, one of the cylinders 8, and the lever 9 to rotate). Before the lever mechanism contacts the winder handle 7, the driven sprocket 5 is rotated by the torque return spring. Spring 16 drives the limiting disk 11 to perform concentric circular motion (and at this time, the control adjustment mechanism connects the limiting disk 11 to the upper cylinder 10, so that the rotation of the limiting disk 11 can drive the upper cylinder 10, one of the cylinders 8 and the lever 9 to rotate), and drives the code disk 12 to rotate, which in turn drives the lever mechanism to move up and down in an arc. The photoelectric U-shaped through-beam sensor 14 is fixed on the bracket 17. Therefore, when the code disk 12 rotates, the photoelectric U-shaped through-beam sensor 14 outputs a square wave signal. The light emitted by the photoelectric U-shaped through-beam sensor 14 can pass through the through hole 13. During the circular motion, the through holes 13 equidistantly opened on the code disk 12 will block and pass through the light of the photoelectric U-shaped through-beam sensor 14, causing the photoelectric U-shaped through-beam sensor 14 to output a regular square wave signal. When the lever 9 contacts the winding machine handle 7, the cylinder 8, the upper cylinder 10, and the limiting plate 11 stop together (the opening and closing of the winding machine handle 7 is achieved by the cylinder 8 starting the lever 9 to move left and right; the winding machine handle 7 cannot be pushed downwards, so it will stop flipping when it contacts the handle). The driven sprocket 5 will continue to rotate, and the code disk 12, which is mounted on the limiting plate 11, will also stop rotating. The photoelectric U-shaped through-beam sensor 14 will stop outputting square wave signals. At this time, the driven sprocket 5 can still rotate, thereby driving the push rod 19 to slide in the arc groove 18. At this time, the torque return spring 16 applies pressure to the limiting plate 11, thereby making the lever mechanism more closely contact the winding machine handle 7. The torque of the torque return spring 16 makes the contact more reliable. At this time, the drive motor 2 is still moving, but the limit plate 11 stops, causing the encoder 12 to stop running. The photoelectric U-shaped through-beam sensor 14 no longer outputs a square wave signal. When the processing controller outputs the drive signal of the drive motor 2, once it detects that the photoelectric U-shaped through-beam sensor 14 has no square wave signal output, it indicates that the lever mechanism has contacted the winding machine handle 7. The processing controller then stops outputting the drive signal of the drive motor 2, stops driving the driven sprocket 5, and then stops the operation of the lever mechanism. This protects the lever mechanism from continuously driving the winding machine handle 7, which could cause equipment damage. Subsequently, the controller controls the corresponding cylinder 8 to run, and the winding machine handle 7 can be opened for replacement.

[0025] In summary, through the design of the above structure, the signal that the automatic yarn cart lever mechanism has contacted the winding handle 7 can be obtained through simple algorithm processing. Moreover, the lever mechanism has a simple and reliable structure, is highly responsive, and is not easily damaged even after long-term use.

[0026] Based on the above embodiments, it was found during use that the existing automatic yarn storage carts of winding machines generally adopt a configuration of one lever 9 and one code meter. Each lever 9 needs to be independently equipped with a code disk 12 and a photoelectric U-shaped through-beam sensor 14 to detect whether it is in contact with the yarn support. When multiple sets of levers 9 are connected in parallel and operate simultaneously, the number of code meters increases exponentially with the levers 9, which not only takes up space and increases costs, but also causes complicated wiring and difficulty in signal aggregation, making it difficult to achieve the integrated detection requirements of compact structure and easy maintenance. In order to solve the above problems, further improvements have been made to the above structure.

[0027] The adjustment mechanism includes an electric telescopic cylinder 25, and a pair of electric telescopic cylinders 25 are provided. A fixed frame 26 is fixedly connected to the front side of the limiting plate 11. The electric telescopic cylinders 25 are fixedly connected to the upper and lower sides of the fixed frame 26 respectively. The front sides of the upper cylinder 10 and the lower cylinder 15 extend to the rear side of the fixed frame 26. An annular groove 27 is opened on the front side of the upper cylinder 10 and the lower cylinder 15. A fixed plate 28 is fixedly connected to the inner side of the annular groove 27. A touch sensor 44 is fixedly connected to the side wall of the fixed plate 28. The touch sensor 44 is electrically connected to the corresponding cylinder 8 through the controller. A pair of upper rods 29 are slidably connected through both ends of the inner side of the fixed frame 26. A pair of adjusting blocks 31 are slidably connected to the inner side of the fixed frame 26. Slide grooves are opened on the upper and lower sides of the fixed frame 26. L-shaped plates 32 are slidably connected to the inner side of the slide grooves. The L-shaped plates 32 are fixedly connected to the outer wall of the corresponding adjusting blocks 31 respectively. The output end of the electric telescopic cylinder 25 is fixedly connected to the side wall of the L-shaped plate 32. Upper springs 30 are fixedly connected between the outer wall of the upper rod 29 and the inner side of the fixed frame 26. The rear ends of the adjusting block 31 are inclined on both sides, and the side ends of the upper rod 29 are set as smooth arc surfaces. When the drive lever 9 flips down and contacts the winding machine handle 7, the two electric telescopic cylinders 25 are first controlled to start and drive the L-shaped plate 32 to move towards the middle, and at the same time drive the adjusting block 31 to move towards the middle. At this time, the adjusting block 31 will move to one of the upper rods 29. Since the upper rod 29 can only slide laterally on the fixed frame 26, under the action of the inclined surface of the adjusting block 31 pressing the arc surface of the upper rod 29, the upper rod 29 will slide backward and compress the upper spring 30. At this time, the two upper rods 29 will be inserted into the annular groove 27 in the upper cylinder 10. Then, the electric telescopic cylinder 25 can be stopped and the transmission mechanism can be operated. When the driven sprocket 5 drives the limit plate 11 to rotate, it will drive the fixed frame 26 and the extended upper rod 29 to rotate in the annular groove 27. Then the upper rod 29 moves to the side of the fixed plate 28 and touches the corresponding touch sensor 44. At this time, the touch sensor 44 sends a signal to the controller. The controller controls the upper electromagnet 23 to be de-energized. After the lever 9 touches the winding machine handle 7, the controller controls the corresponding cylinder 8 to start, thereby pushing the upper cylinder 10 to rotate through the upper rod 29 (at this time, the lower cylinder 15 is attracted and fixed by the lower electromagnet 24 and cannot rotate, while the upper electromagnet 23 on the upper cylinder 10 is de-energized). This drives the corresponding cylinder 8 and lever 9 to rotate until the lever 9 is released to the winding machine handle 7 to stop rotating. The signal is transmitted through the code disk positioning mechanism, and the controller controls the drive motor 2 to stop running and controls the corresponding cylinder 8 to run, so as to realize the self-positioning opening of the corresponding winding machine handle 7. Finally, control the electric telescopic cylinder 25 to continue moving, so that the adjusting block 31 moves away from the first upper rod 29 and moves to the other upper rod 29. Repeat the above operation to squeeze the other upper rod 29 backward and insert it into the annular groove 27 in the lower cylinder 15. (It should be noted that in order to ensure that the upper rod 29 does not insert into the fixed plate 28 when it is inserted, a sensor can be set for positioning to ensure the normal operation of the equipment.) At this time, the compression of the first upper rod 29 will be released, and then it will be pushed back to its original position under the elastic force of the upper spring 30. At this time, the compression of the torque return spring 16 will be released, so that the limit plate 11 will be driven to reset under the elastic force of the torque return spring 16. Then control the drive motor 2 to continue running and repeat the above operation.

[0028] In summary, the above structural design allows multiple lever mechanisms on the yarn warehouse cart to share a single transmission mechanism and code disk positioning mechanism, thereby reducing wiring, cost, and installation space, making it suitable for densely arranged automatic yarn warehouse carts.

[0029] Based on the above embodiments, it was found during use that although the above structure can realize the function of multiple lever mechanisms sharing one code disk positioning mechanism, in actual use, in order to improve work efficiency, the number of replacement levers 9 of the yarn warehouse will increase. The above structure cannot be directly expanded and installed on the original structure, and cannot meet the diverse needs of users. In order to solve the above problems, further improvements have been made to the above structure.

[0030] The inner side of the fixed frame 26 has two pairs of expansion holes 33. An expansion rod 34 is inserted into the inner side of one pair of expansion holes 33. A lower spring 35 is fixedly connected to the outer wall of the expansion rod 34. The front end of the expansion rod 34 is set as a smooth arc surface. U-shaped frames 36 are fixedly connected to both sides of the inner side of the fixed frame 26 relative to the expansion holes 33. A pair of L-shaped blocks 37 are fixedly connected to the other end of the lower spring 35. An expansion frame 38 is bolted to the rear side of the support base 21. An expansion cylinder 39 is rotatably connected through the expansion frame 38. An electromagnet for attracting and fixing the position of the expansion cylinder 39 is provided on the expansion frame 38. An expansion lever 40 is fixedly connected to the rear end of the expansion cylinder 39. The front side of the expansion cylinder 39 is rotatably connected to the inside of the lower cylinder 15. An expansion ring groove 41 is opened on the front side of the expansion cylinder 39. A pair of expansion plates 42 are fixedly connected to the inside of the expansion ring groove 41. An expansion sensor 43 is fixedly connected to the side wall of the expansion plate 42. When it is necessary to increase the number of levers 9, first insert the expansion lever 34 into the expansion hole 33, insert the L-shaped block 37 on the lower spring 35 into the U-shaped frame 36, and install the expansion frame 38 on the support base 21 with bolts. At the same time, insert the expansion cylinder 39 into the lower cylinder 15 to complete the expansion installation. Then, during subsequent operation, control the electric telescopic cylinder 25 to drive the adjusting block 31 to squeeze the expansion lever 34 into the expansion ring groove 41. The expansion lever 34 pushes the expansion plate 42 to rotate and touch the expansion sensor 43 to realize the operation of the expansion lever 40.

[0031] In summary, the above structural design allows for rapid expansion of the existing code meter device while sharing the original code disk positioning mechanism. This enables flexible expansion based on user needs, further enhancing the device's flexibility.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0033] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
