Description

Technical Field

[0001] This invention relates to the field of spinning frame technology, and in particular to a single-spindle roving feeding automatic stop device and method. Background Technology

[0002] The production unit of a ring spinning machine is the spindle. The production level of a ring spinning machine is usually measured by the output per thousand spindle hours. The yarn spun on each spindle may break due to various reasons. The breakage rate is usually expressed as the number of breakages per thousand spindle hours. The breakage rate affects labor productivity, equipment productivity, yarn quality, and dust content in the workshop. During the production process of a ring spinning machine, production must be stopped when a package (bore) is spun. Spinning can only continue after the bobbin is dropped and replaced with an empty bobbin. Therefore, the size of the package affects labor productivity, equipment productivity, and energy consumption.

[0003] A search revealed that the invention disclosed in CN110106588B is a ring spinning machine with easy spindle replacement. It features a novel structure and convenient operation, allowing for quick spindle replacement. However, this machine also has the following drawbacks: replacement is achieved by swapping the spindle to be replaced with the replacement spindle; however, the spindle to be replaced still requires manual placement, undoubtedly increasing the workload of workers and resulting in low efficiency and inconvenience. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as the need for manual placement of the spindles to be replaced, which undoubtedly increases the workload of workers, and is inefficient and inconvenient to use. Therefore, this invention proposes a single-spindle roving feeding automatic stop device and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A single-spindle roving feeding self-stop device includes a spinning frame, wherein a changing frame is provided on one side of the spinning frame, and the changing frame is provided with two sets of spindle seats for alternating use;

[0007] The replacement frame includes a first support and a second support fixed on the ground. A rotating rod is provided between the first support and the second support. Both sets of spindle seats are fixed on the rotating rod. A first motor is fixed on one side of the first support. The output end of the first motor is connected to the rotating rod to provide rotational power to the rotating rod and change the position of the two sets of spindle seats.

[0008] A collection box, located on one side of the changing frame, is used to collect the bobbins falling from the spindle seat;

[0009] The feeding box is located on one side of the spinning machine and is used to hold empty tubes. The bottom of the feeding box has a rectangular opening, and a conveyor for conveying empty tubes is provided in the rectangular opening. The conveyor is located below the changing frame so that the conveyed empty tubes correspond to the spindle seats. During the process of replacing the spindle seats, the empty tubes are fitted onto the corresponding spindle seats.

[0010] The feeding mechanism is located inside the feeding box and works in conjunction with the conveyor to feed empty pipes, so that the empty pipes fall onto the conveyor in sequence.

[0011] In one possible design, a transmission rod is rotatably connected between the first bracket and the second bracket. An incomplete gear is fixedly sleeved on the outer wall of the transmission rod. A second rack that meshes with the incomplete gear is slidably provided on the inner side of both the first bracket and the second bracket. Two sliding blocks are rotatably sleeved on the outer wall of the rotating rod. The sliding blocks are fixedly connected to the corresponding second racks. A waist-shaped hole is opened on one side of both the first bracket and the second bracket. Both ends of the rotating rod are located in the corresponding waist-shaped hole.

[0012] In one possible design, the outer wall of the rotating rod is fitted with a first gear through a one-way bearing, and the outer sides of the first and second supports are both fixedly fitted with a first rack that meshes with the first gear. The outer wall of the rotating rod is fixedly fitted with an electromagnet corresponding to the sliding block.

[0013] In one possible design, two arc-shaped plates are fixedly installed inside the feeding box. A first guide plate and a second guide plate for guiding empty tubes are respectively fixed between the two arc-shaped plates and the inner walls on both sides of the feeding box. The first guide plate and the second guide plate form a first receiving cavity for holding empty tubes between the feeding box and the two ends of the arc-shaped plates. A feed inlet and a discharge outlet are formed between the two ends of the two arc-shaped plates. A rotating shaft located between the two arc-shaped plates is rotatably installed through one side of the feeding box. The rotating shaft is used in conjunction with a conveyor. A plurality of evenly distributed partitions are fixedly installed on the outer wall of the rotating shaft. A second receiving cavity is formed between two adjacent partitions.

[0014] In one possible design, the conveyor includes two side strips fixed to the ground, two drive rollers rotatably connected between the two side strips, the outer walls of the two drive rollers being connected to the same conveyor belt, a plurality of positioning blocks cooperating with the rotating shaft being fixedly provided on the outer walls of the drive rollers, the top of the positioning blocks being provided with positioning grooves for corresponding empty tubes, a second motor being fixedly provided on one side of one of the side strips, the output end of the second motor being fixedly connected to the corresponding drive roller.

[0015] In one possible design, a fixing block is fixedly provided on one side of the feeding box, a sliding rod is slidably provided through the top of the fixing block, a lifting block that cooperates with the positioning block is fixedly provided at the bottom of the sliding rod, a connecting block is fixedly provided at the top of the sliding rod, a tension spring is sleeved on the outer wall of the sliding rod, and the two ends of the tension spring are respectively fixedly connected to the adjacent sides of the connecting block and the fixing block, and a rotating ring is sleeved on the outer wall of the rotating shaft. The rotating ring is connected to the connecting block through a connecting piece and is used to drive the rotating shaft to rotate.

[0016] In one possible design, the connector includes a connecting rod fixedly disposed on the outer wall of the rotating ring, a clearance hole is provided on one side of the connecting rod, a connecting post is provided in the clearance hole, the connecting post is fixedly connected to the connecting block, and the rotating ring is sleeved on the rotating shaft through a one-way bearing.

[0017] In one possible design, an elastic strip is fixedly provided on one inner wall of the positioning groove, and a baffle for positioning the empty tube is fixedly provided on the top of the elastic strip.

[0018] In one possible design, the top of the positioning block is fixed with an arc-shaped block that works in conjunction with the lifting block, and the outer side of the arc-shaped block is arc-shaped.

[0019] A method for using a single-spindle roving feeding automatic stop device includes the following steps:

[0020] S1. First, place the empty tube in the feeding box, then start the second motor to drive the positioning block to move and convey the empty tube until the empty tube stops under the rotating rod in sequence.

[0021] S2. Then start the first motor to drive the rotating rod to move upward. During the upward movement of the rotating rod, it will drive the rotating rod to rotate through the first rack. During the rotation, it can drive the spindle seat to insert into the corresponding empty tube and drive the empty tube to rotate to one side of the spinning machine. After the rotation is completed, it will automatically fall down.

[0022] S3. Then start the spinning machine to process the yarn, so that the yarn is wound on the empty tube, and at the same time continue to start the second motor to deliver the empty tube;

[0023] S4. When the bobbin is fully spun, the first motor is started again to drive the rotating rod to move upward and rotate. During the rotation, the spindle seat on one side is inserted into the empty tube and drives the empty tube to move to the side of the spinning machine. At the same time, the bobbin will automatically fall into the collection box under the action of gravity.

[0024] In this application, firstly, the empty tube is placed in the feeding box. The empty tube then moves through the first guide plate, the second guide plate, and the feed inlet to the second receiving cavity. Next, the second motor is started, driving the transmission roller to rotate. The rotation of the transmission roller drives the conveyor belt to move, which in turn moves the positioning block. During this movement, the arc-shaped block drives the lifting block to move upwards. The upward movement of the lifting block drives the sliding rod to move upwards, which in turn drives the connecting block to move upwards. As the connecting block moves upwards, it drives the rotating ring to rotate via the connecting column and connecting rod. The rotation of the rotating ring then drives the rotating shaft to rotate. The rotation of the rotating shaft can drive the empty tube to move through the partition. When the second receiving cavity corresponds to the feeding port, the empty tube will fall and land in the positioning groove on the positioning block. It continues to move. When the arc-shaped block moves away from the lifting block, the tension spring can drive the connecting block to move downward and drive the lifting block to move downward through the sliding rod. At the same time, the rotating ring is driven to rotate in the opposite direction through the connecting column and the connecting rod. Since the rotating ring and the rotating shaft are connected by a one-way bearing, the rotating ring will not drive the rotating shaft to rotate during the reverse rotation. The empty tubes are conveyed in sequence until they stop below the rotating rod and correspond to the corresponding spindle seat.

[0025] Then, the first motor is started, which drives the transmission rod to rotate. The rotation of the transmission rod drives the incomplete gear to rotate, which in turn drives the second rack to move upward. The upward movement of the second rack drives the rotating rod to move upward through the sliding block. During the upward movement of the rotating rod, it drives the rotating rod to rotate through the first rack and the first gear. During the rotation, it drives the spindle seat on one side to insert into the corresponding empty tube and drives the empty tube to rotate to one side of the spinning machine. At the same time, the electromagnetic block on the outer wall of the rotating rod is activated, so that it is attracted to the sliding block and fixed to the rotating rod. When the notch of the incomplete gear corresponds to the second rack, the second rack will automatically fall under the force of the sliding block and the transmission roller, while the first gear will not drive the rotating rod to rotate under the force of the one-way bearing.

[0026] Then start the spinning machine to process the yarn, so that the yarn is wound on the empty tube, while the second motor continues to be started to deliver the empty tube.

[0027] Once the bobbin is fully spun, the first motor is started again to drive the rotating rod to move upward and rotate. During the rotation, the spindle seat on one side is inserted into the empty tube and moves the empty tube to the side of the spinning machine. At the same time, the bobbin will automatically fall into the collection box under the action of gravity.

[0028] Beneficial effects:

[0029] In this invention, the single-spindle roving feeding self-stop device can sequentially convey empty tubes by setting multiple baffles on the rotating shaft, and can drive the rotating shaft to rotate during the movement of the arc block, thereby saving power source and ensuring that the empty tube falls into the positioning groove on the positioning block, thus improving the accuracy of automatic placement of empty tubes.

[0030] In this invention, the single-spindle roving feeding self-stop device, by setting a baffle in the positioning groove, can position the empty tube, ensuring that the empty tube will not be pushed out of the positioning groove during the movement of the spindle seat, thereby improving the accuracy of the insertion of the spindle seat and the empty tube.

[0031] In this invention, the single-spindle roving feeding self-stop device can not only drive the rotating rod to move upward by starting the first motor, but also drive the rotating rod to rotate, so that the two sets of spindle seats can be swapped, and the bobbin yarn can be fed and the empty bobbin can be fed, making it easy to operate and reducing the labor of workers.

[0032] In this invention, the combined use of the feeding box, conveyor, and changing frame can move the empty tube to below the spindle seat and rotate one side of the spindle seat to insert into the empty tube. At the same time, it can straighten the position of the empty tube so that it does not need to be placed manually. Furthermore, as one side of the spindle seat rotates, the yarn tube on the other side of the spindle seat will automatically fall into the collection box, eliminating the need for manual unloading and making it more convenient to use.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1

[0044] Reference Figures 1-8 A single-spindle roving feeding automatic stop device, which is used in the field of spinning frame, includes: spinning frame 1, spinning frame 1 adopts Rieter ring spinning frame G37, a changing frame 3 is provided on one side of spinning frame 1, and two sets of spindle seats 2 are provided on the changing frame 3 for alternating use.

[0045] The replacement frame 3 includes a first support 7 and a second support 8 fixed on the ground. A rotating rod 9 is provided between the first support 7 and the second support 8. Both sets of spindle seats 2 are fixed on the rotating rod 9. A first motor 10 is fixed on one side of the first support 7. The output end of the first motor 10 is connected to the rotating rod 9 to provide rotation power to the rotating rod 9 and change the position of the two sets of spindle seats 2.

[0046] Collection box 4 is located on one side of the changing frame 3 and is used to collect the bobbin yarn falling from the spindle seat 2.

[0047] The feeding box 5 is located on one side of the spinning machine 1 and is used to hold empty tubes. The bottom of the feeding box 5 has a rectangular opening 33. The rectangular opening 33 is equipped with a conveyor 6 for conveying empty tubes. The conveyor 6 is located below the changing frame 3, so that the conveyed empty tubes correspond to the spindle seats 2. During the replacement of the spindle seats 2, the empty tubes are fitted onto the corresponding spindle seats 2.

[0048] The feeding mechanism, located in the feeding box 5 and used in conjunction with the conveyor 6, is used to feed empty tubes, allowing them to fall sequentially onto the conveyor 6. Starting the conveyor 6 drives the feeding mechanism to feed the empty tubes, ensuring they align with their corresponding spindle seats 2. When the yarn on another set of spindle seats 2 needs feeding, starting the first motor 10 drives the rotating rod 9 to rotate, causing the two sets of spindle seats 2 to switch positions. During this adjustment, the yarn falls into the collection box 4, while the empty tubes are inserted into the spindle seats 2 for further processing. This improves processing efficiency and makes the machine more convenient to use. To control the yarn breakage rate and achieve unattended spinning, a detection probe is installed on each spindle position of the spinning machine. The probe detects the wire running speed, and the data is continuously transmitted to the MS lower-level machine, which assigns an address to each spindle. When a spindle breaks, the traveler stops moving. Upon receiving the signal, the MS (Microcontroller Unit) controls the corresponding cutting device to cut the roving at the broken spindle location. Furthermore, if the spindle exhibits abnormal speed, such as slippage, the indicator will display different colors, warning the user to address the issue and prevent defective yarn. Upgrading this system will also allow all data to be transmitted to a server via the internet and stored for future development.

[0049] Two arc-shaped plates 29 are fixedly installed inside the feeding box 5. A first guide plate 27 and a second guide plate 28 for guiding empty tubes are respectively fixed between the two arc-shaped plates 29 and the inner walls on both sides of the feeding box 5. The first guide plate 27 and the second guide plate 28 form a first receiving cavity 30 for holding empty tubes between the feeding box 5. A feed inlet 31 and a discharge outlet 32 ​​are formed between the two ends of the two arc-shaped plates 29. A rotating shaft 35 located between the two arc-shaped plates 29 is rotatably installed through one side of the feeding box 5. The rotating shaft 35 is connected to the conveyor 6. When used together, the outer wall of the rotating shaft 35 is fixedly provided with a plurality of evenly distributed partitions 36, and a second receiving cavity 37 is formed between two adjacent partitions 36. When the conveyor 6 is started, it can drive the rotating shaft 35 to rotate. When the rotating shaft 35 can drive the partitions 36 to move and move the position of the second receiving cavity 37, when the second receiving cavity 37 corresponds to the feed port 31, the empty tube falls into the second receiving cavity 37. When the second receiving cavity 37 corresponds to the discharge port 32, the empty tube will fall onto the conveyor 6, and the empty tube can be conveyed in sequence.

[0050] The conveyor 6 includes two side strips 18 fixed to the ground, and two drive rollers 19 rotatably connected between the two side strips 18. The outer walls of the two drive rollers 19 are connected to the same conveyor belt 20. Multiple positioning blocks 21 that cooperate with the rotating shaft 35 are fixed on the outer walls of the drive rollers 19. The top of the positioning block 21 is provided with a positioning groove 23 for corresponding empty pipes. A second motor 22 is fixed on one side of one of the side strips 18. The output end of the second motor 22 is fixedly connected to the corresponding drive roller 19. By starting the second motor 22, the drive roller 19 can be driven to rotate. The rotation of the drive roller 19 can drive the conveyor belt 20 to move and drive the positioning block 21 to move. At the same time, the positioning block 21 can drive the rotating shaft 35 to rotate during the movement, causing the empty pipe to fall. The positioning groove 23 can catch the empty pipe and prevent the empty pipe from rolling on the conveyor 6.

[0051] A fixing block 38 is fixedly provided on one side of the feeding box 5. A sliding rod 39 is slidably provided through the top of the fixing block 38. A lifting block 34 that cooperates with the positioning block 21 is fixedly provided at the bottom of the sliding rod 39. A connecting block 40 is fixedly provided at the top of the sliding rod 39. A tension spring 41 is sleeved on the outer wall of the sliding rod 39. The two ends of the tension spring 41 are fixedly connected to the adjacent sides of the connecting block 40 and the fixing block 38, respectively. A rotating ring 42 is sleeved on the outer wall of the rotating shaft 35. The rotating ring 42 is connected to the connecting block 40 through a connector and is used to drive the rotating shaft 35 to rotate. During the movement of the positioning block 21, it will abut against the lifting block 34 and drive the lifting block 34 to move upward. The upward movement of the lifting block 34 can drive the connecting block 40 to move upward through the sliding rod 39. When the connecting block 40 moves upward, it can drive the rotating ring 42 and the rotating shaft 35 to rotate through the connector, which can feed empty tubes. When the positioning block 21 moves away from the lifting block 34, the sliding rod 39 can move downward to reset under the force of the tension spring 41 without the need for an additional power source.

[0052] Example 2

[0053] refer to Figures 1-8An improvement based on Embodiment 1: A transmission rod 11 is rotatably mounted between the first support 7 and the second support 8. An incomplete gear 16 is fixedly mounted on the outer wall of the transmission rod 11. A second rack 17 that meshes with the incomplete gear 16 is slidably mounted on the inner side of both the first support 7 and the second support 8. Two sliding blocks 12 are rotatably mounted on the outer wall of the rotating rod 9. The sliding blocks 12 are fixedly connected to the corresponding second rack 17. A waist-shaped hole 13 is opened on one side of both the first support 7 and the second support 8. Both ends of the rotating rod 9 are located in the corresponding waist-shaped hole 13. By starting the first motor 10, the transmission rod 11 can be driven to rotate. When the transmission rod 11 rotates, it can drive the second rack 17 to move upward. The sliding blocks 12 push the rotating rod 9 to move upward, so that the spindle seat 2 corresponds to the corresponding empty tube. When the notch of the incomplete gear 16 corresponds to the second rack 17, the sliding block 12 can move downward under the action of gravity, automatically adjusting the height of the empty tube.

[0054] The outer wall of the rotating rod 9 is fitted with a first gear 14 through a one-way bearing. The outer sides of the first bracket 7 and the second bracket 8 are both fixed with a first rack 15 that meshes with the first gear 14. The outer wall of the rotating rod 9 is fixed with an electromagnet corresponding to the sliding block 12. When the sliding block 12 drives the rotating rod 9 to move upward, it can drive the rotating rod 9 to rotate through the first rack 15 and the first gear 14. The rotation of the rotating rod 9 can drive the two sets of spindle seats 2 to rotate and change positions. At the same time as the rotating rod 9 moves downward, the electromagnet is activated so that the electromagnet is attracted to the sliding block 12. At this time, when the rotating rod 9 moves downward, the first gear 14 rotates in the opposite direction under the force of the first rack 15. Due to the action of the one-way bearing, the rotating rod 9 will not be driven to rotate, making it more stable when moving downward.

[0055] An elastic strip 24 is fixedly provided on one side of the inner wall of the positioning groove 23. A baffle 25 for positioning the empty tube is fixedly provided on the top of the elastic strip 24. By setting the baffle 25 in the positioning groove 23, the empty tube can be positioned. During the process of inserting the spindle seat 2 and the empty tube, the empty tube can abut against the baffle 25 to deform the elastic strip 24, so that the empty tube can be stably inserted into the spindle seat 2.

[0056] The top of the positioning block 21 is fixed with an arc-shaped block 26 that works with the lifting block 34. The outer side of the arc-shaped block 26 is arc-shaped. By setting the arc-shaped block 26 on the positioning block 21, and the arc-shaped block 26 is arc-shaped, it will not jam with the lifting block 34 during the process of working with it, and the movement is smoother.

[0057] The connecting component includes a connecting rod 43 fixedly mounted on the outer wall of the rotating ring 42. A clearance hole 44 is provided on one side of the connecting rod 43, and a connecting post 45 is provided in the clearance hole 44. The connecting post 45 is fixedly connected to the connecting block 40. The rotating ring 42 is sleeved on the rotating shaft 35 through a one-way bearing. When the lifting block 34 drives the connecting block 40 to move upward, it can drive the rotating ring 42 and the rotating shaft 35 to rotate through the connecting post 45 and the connecting rod 43. When the connecting block 40 moves downward to reset, it can drive the rotating ring 42 to rotate in the opposite direction through the connecting post 45 and the connecting rod 43. Due to the setting of the one-way bearing, the reset rotation of the rotating ring 42 will not drive the rotating shaft 35 to rotate.

[0058] A method for using a single-spindle roving feeding automatic stop device includes the following steps:

[0059] S1. First, place the empty tube in the feeding box 5, then start the second motor 22 to drive the positioning block 21 to move and convey the empty tube until the empty tube stops below the rotating rod 9 in sequence.

[0060] S2. Then start the first motor 10 to drive the rotating rod 9 to move upward. During the upward movement of the rotating rod 9, it will drive the rotating rod 9 to rotate through the first rack 15. During the rotation, it can drive the spindle seat 2 to insert into the corresponding empty tube and drive the empty tube to rotate to one side of the spinning machine 1. After the rotation is completed, it will automatically fall down.

[0061] S3. Then start the spinning machine 1 to process the yarn so that it is wound on the empty tube, while continuing to start the second motor 22 to deliver the empty tube.

[0062] S4. When the bobbin is fully spun, the first motor 10 is started again to drive the rotating rod 9 to move upward and rotate. During the rotation, the spindle seat 2 on one side is inserted into the empty tube and drives the empty tube to move to the side of the spinning machine 1. At the same time, the bobbin will automatically fall into the collection box 4 under the action of gravity.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the spinning machine 1, the first motor 10 and the second motor 22 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
