Description

Technical Field

[0001] The present invention relates to the technical field of spinning quality detection, and specifically to a spinning quality detection management method and system. Background Art

[0002] Spinning is a process of forming slivers and drawing and twisting them into yarns by specific processing methods for various fibers (such as cotton, linen, silk, wool and chemical fibers). The spinning process is divided into two main stages: sliver forming and yarn forming. Spinning quality refers to the standards and requirements achieved by the yarns produced during the spinning process in terms of physical and chemical properties. The quality of spinning directly affects the quality and performance of the final textile products. For example, if the hairiness is too long, the yarn is likely to be entangled and broken, which will not only increase the production cost of spinning, but also affect the quality and aesthetics of the spinning products.

[0003] In order to understand the quality of each batch of spun yarns, quality management inspections are carried out on the corresponding yarns. The inspections include tensile tests and hairiness tests. However, the conventional testing methods require manual intervention throughout the process. The operators need to switch the yarns back and forth and transfer the yarns to the corresponding testing equipment. The operation is cumbersome, the degree of automation is low, and the accuracy of the test results needs to be improved. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spinning quality detection management method and system. The type of yarn is switched by a yarn changing mechanism, and the yarn hooking mechanism can automatically transfer the yarn to the yarn winding and unwinding mechanism, solving the trouble of manual threading, realizing automatic winding of the yarn, and being able to online detect the tensile data and hairiness value of the yarn under the mutual cooperation of the yarn pulling mechanism and the hairiness component, automatically collecting various data of the yarn, saving manpower and improving the accuracy of the test results, so as to solve the problems raised in the above-mentioned background art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A spinning quality detection system includes a quality detector. A top platform is provided on the outer wall of the top of the quality detector, and a yarn changing mechanism for switching yarns is installed on the top platform. A yarn hooking mechanism for hooking the yarn, a yarn pulling mechanism for measuring the tensile force of the yarn, a hairiness component for measuring the hairiness value of the yarn, and a yarn winding and unwinding mechanism for winding and pushing down the yarn are installed on the outer wall of one side of the quality detector. Among them, the yarn pulling mechanism, the hairiness component and the yarn winding and unwinding mechanism are sequentially installed on one side of the quality detector from top to bottom;

[0007] The yarn changing mechanism is composed of a first servo motor, a fixed frame, a lead screw, a yarn changing seat and yarn clamping heads. Among them, the fixed frame is fixedly connected to the outer wall of the top table, the first servo motor is installed on the outer wall of one end of the fixed frame, the lead screw is fixedly connected to the output shaft of the first servo motor through a coupling, the yarn changing seat is screwed on the outer wall of the lead screw, and there are multiple yarn clamping heads, which are equidistantly distributed and rotatably connected to the outer wall of one side of the yarn changing seat. Driving the lead screw to rotate by the first servo motor can control the translation of the yarn changing seat, and can switch different yarns closer to the yarn hooking member;

[0008] The yarn hooking mechanism includes a rotary cylinder installed on the outer wall of one side of the quality inspection machine, a fixed sleeve arranged on one side of the rotary cylinder, and the fixed sleeve is fixedly connected to the outer wall of one side of the quality inspection machine, a semi-gear fixedly connected to the output shaft of the rotary cylinder, and the semi-gear is arranged inside the fixed sleeve, a rack meshed with the outer wall of the semi-gear, a disc fixedly connected to the outer wall of one end of the rack, an internally threaded column rotatably connected to the outer wall of one side of the disc, a chuck clamped to the inner wall of the fixed sleeve, and one end of the chuck is slidably connected to the internal thread groove of the internally threaded column, and a yarn hooking member is fixedly connected to the outer wall of one end of the internally threaded column. Among them, the yarn hooking member is composed of a long rod and a thin hook. When the rotary cylinder drives the semi-gear to rotate, it can drive the rack to move back and forth. Under the limiting action of the chuck, it can control the internally threaded column to rotate and move at the same time. On the one hand, it is convenient for the yarn hooking member to hook the yarn when it is at the highest point, and on the other hand, it is convenient for the yarn hooking member to automatically release the yarn when it is at the lowest point.

[0009] As a further solution of the present invention, the yarn pulling mechanism is composed of a first cylinder, a connecting kit, a yarn pulling member, an electric guide rail and a tension sensor. Among them, the first cylinder is fixedly connected to the outer wall of one side of the quality inspection machine, the connecting kit is installed on the piston rod of the first cylinder, and the yarn pulling member is arranged at both ends of the connecting kit. Among them, there are two yarn pulling members, which are symmetrically distributed up and down. The electric guide rail is fixedly connected to the outer wall of one side of the quality inspection machine, and the tension sensor is installed between the slider of the electric guide rail and the yarn pulling member. Using the first cylinder to push the connecting kit can control the yarn pulling member to clamp the yarn, and by pushing one of the yarn pulling members to move down by the electric guide rail, the tension sensor can monitor the tension data in real time, realizing the online detection of the yarn and accurately understanding the tensile strength and elasticity of the yarn;

[0010] The connecting kit is composed of a square tube sleeve and a square rod. Among them, the square tube sleeve is fixedly connected to the piston rod of the first cylinder, and the square rod is slidably connected to the inner wall of the square tube sleeve. The square tube sleeve and the square rod can, on the one hand, push the yarn pulling member to clamp the yarn, and on the other hand, can also change the overall length with the movement of the slider of the electric guide rail, with strong adaptability and the function of conducting force;

[0011] The yarn pulling member is composed of a square plate, a C-shaped mother block, and a T-shaped son block. Among them, there are two square plates. One square plate is fixedly connected to the outer wall of one side of the quality inspection machine, and the other square plate is fixedly connected to the bottom outer wall of the tensile sensor. The C-shaped mother block is welded to the outer wall of one side of the square plate. There are two T-shaped son blocks. One side of the T-shaped son block is fixedly connected to one end of the square tube sleeve and the square rod, and one side of the T-shaped son block is slidably connected to the inner wall of the square plate. By moving the T-shaped son block closer to the C-shaped mother block, the T-shaped son block can be controlled to move into the groove of the C-shaped mother block, thereby clamping the yarn, which has a very high firmness.

[0012] As a further scheme of the present invention, the hairiness member includes a docking plate symmetrically distributed on the outer wall of one side of the quality inspection machine, a yarn guide piece fixedly connected to the outer wall of one side of the docking plate, and a vibration sensor installed on the outer wall of the other side of one of the docking plates. After the yarn passes through the two docking plates, it can contact the yarn guide piece. As the yarn continuously moves, the yarn will generate vibrations on the yarn guide piece. By relying on the vibration sensor to sense the vibration frequency, the hairiness value of the yarn can be detected.

[0013] As a further scheme of the present invention, the yarn winding and unwinding mechanism is composed of a yarn winding member, a passive gear, a driving gear, a rotating column, a servo motor two, and an unwinding member. Among them, the yarn winding member is rotatably connected to the inner wall of one side of the quality inspection machine, the passive gear is fixedly connected to the outer wall of the yarn winding member, the driving gear is meshed with the outer wall of the passive gear, the rotating column is fixedly connected to the inner wall of the driving gear, the servo motor two is fixedly connected to the outer wall of one end of the rotating column through a coupling, one end of the unwinding member is installed inside the quality inspection machine, and the other end of the unwinding member is arranged inside the yarn winding member. By driving the driving gear to rotate by the servo motor two, the yarn winding member on the inner wall of the passive gear can be controlled to rotate, and the yarn can be continuously wound around the outer wall of the yarn winding member, which provides convenience for the tensile test of the yarn and the measurement of the hairiness value. And as the unwinding member works, the yarn can be automatically pushed away, eliminating the need for manual thread removal and saving manpower.

[0014] As a further scheme of the present invention, the yarn winding member includes a barrel sleeve rotatably connected to the inner wall of the quality inspection machine, a horn sleeve arranged at one end of the barrel sleeve, a yarn clamping groove opened on the inner wall of the horn sleeve, and a rear retaining ring fixedly connected to the outer wall of the barrel sleeve. After the yarn is hooked into the yarn clamping groove by a thin hook, the winding operation can be carried out by rotating the barrel sleeve, and the yarn will be continuously wound between the horn sleeve and the rear retaining ring on the barrel sleeve.

[0015] As a further solution of the present invention, the yarn withdrawing member includes a second cylinder fixedly connected to the inner wall of the quality inspection machine, a connecting column fixedly connected to the piston rod of the second cylinder, and a horizontal push plate welded to the outer wall of one end of the connecting column, and the horizontal push plate is slidably connected to the inner wall of the yarn winding member. After the yarn is wound, the connecting column is pushed by the second cylinder to drive the horizontal push plate to move, so that the yarn can be pushed away from the sleeve, completing the yarn withdrawing operation.

[0016] As a further solution of the present invention, the top outer wall of the yarn changing seat is fixedly connected with a combing wheel distributed at an equal distance, and a Z-shaped block is welded on the top of the outer wall of one side of the yarn changing seat, and the top outer wall of the quality inspection machine is rotatably connected with a yarn roller distributed at an equal distance. The yarn on the yarn roller will pass through the combing wheel and the Z-shaped block and be uniformly clamped on the yarn clamping head, thereby ensuring that each yarn is neatly arranged, which is convenient for fine hooking of yarn.

[0017] As a further solution of the present invention, a yarn guide wheel is installed on the top of the outer wall of one side of the quality inspection machine, and the yarn guide wheel is used to limit the moving trajectory of the yarn to ensure the stability of the yarn when moving.

[0018] As a further solution of the present invention, a PLC electronic controller is installed on the outer wall of one side of the quality inspection machine, and the PLC electronic controller is connected to servo motor 1, rotary cylinder, cylinder 1, electric guide rail, tension sensor, vibration sensor and servo motor 2 through signal lines.

[0019] A management method for a spinning quality detection system comprises the following steps:

[0020] Step 1: First place multiple sets of yarn rollers on the top of the quality inspection machine, then draw the yarn from the yarn rollers through the combing wheel and Z-block in turn, and clamp them in the yarn clamping head;

[0021] Step 2: The rotating cylinder drives the half gear to rotate and control the rack to move, and then controls the internal thread column to rotate and move at the same time. At this time, when the yarn hook rotates to the highest point, the servo motor drives the lead screw to rotate and control the translation of the yarn changing seat, and the thin hook can hook the yarn. As the yarn hook rotates in the opposite direction, the thin hook will clamp the yarn into the yarn clamping groove when it is at the lowest point, and the thin hook will also detach from the yarn as the internal thread column moves;

[0022] Step 3: The servo motor 2 drives the driving gear to rotate and control the yarn winding part to rotate, and the yarn clamped in the yarn clamping groove is continuously wound on the sleeve. The yarn head in the yarn clamping head will be separated from the yarn clamping head due to the tension, so that the yarn on the yarn guide is in a single strand. As the yarn continues to move, the yarn will contact the yarn guide and vibrate on the yarn guide. The vibration sensor senses the vibration frequency and can detect the hairiness value of the yarn. After the hairiness value is detected, the cylinder 2 pushes the connecting column to drive the horizontal push plate to move, so that the yarn can be pushed away from the sleeve to complete the yarn withdrawal operation.

[0023] Step 4: After the yarn stops winding, the cylinder is used to push the connecting kit to clamp the yarn between the T-type sub-block and the C-type mother block. At this time, one of the yarn pulling parts is pushed down by the electric guide rail, and the tension sensor can monitor the tension data in real time until the yarn is broken, and the online collection of the yarn tension data can be completed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The spinning quality inspection and management method and system of the present invention switches the type of yarn through the yarn changing mechanism, and the yarn hooking mechanism can automatically transfer the yarn to the yarn winding and withdrawing mechanism, which solves the trouble of manual threading and realizes the automatic winding of the yarn. In addition, with the cooperation of the yarn pulling mechanism and the hairiness component, the tension data and hairiness value of the yarn can be detected online, and various data of the yarn are automatically collected, which saves manpower and improves the accuracy of the inspection results.

[0026] 2. The spinning quality inspection management method and system of the present invention drives the half gear to rotate and control the movement of the rack through a rotating cylinder, and can control the internal threaded column to rotate and move at the same time. On this basis, the servo motor drives the screw rod to rotate and control the translation of the yarn changing seat, which can facilitate the thin hook to hook the yarn into the yarn clamping groove. The thin hook will also detach from the yarn as the internal threaded column moves. The design is reasonable, and automatic hooking of the yarn is realized, which provides convenience for subsequent quality inspection.

[0027] 3. The spinning quality inspection and management method and system of the present invention realizes automatic winding of the yarn by driving the driving gear to rotate and controlling the rotation of the yarn winding member through servo motor 2. The yarn can vibrate on the yarn guide plate, and the vibration sensor senses the vibration frequency to measure the yarn hairiness value. The connecting column is pushed by cylinder 2 to drive the horizontal push plate to move, so that the yarn can be pushed away from the sleeve to realize automatic yarn withdrawal. At the same time, the clamping between the T-type sub-block and the C-type mother block and the pulling down of the electric guide rail can monitor the tension data in real time through the tension sensor, thereby realizing online collection of yarn tension data. The operation is convenient, the degree of automation is high, and no manual intervention is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Step 3: The servo motor 2 75 drives the driving gear 73 to rotate and control the yarn winding member 71 to rotate, and the yarn clamped in the yarn clamping groove 713 is continuously wound on the sleeve 711. The yarn head in the yarn clamping head 35 is pulled away from the yarn clamping head 35, so that the yarn on the yarn guide piece 62 is in a single state. As the yarn continues to move, the yarn will contact the yarn guide piece 62 and vibrate on the yarn guide piece 62. The vibration sensor 63 senses the vibration frequency and can detect the yarn hairiness value. After the hairiness value is detected, the cylinder 2 761 pushes the connecting column 762 to drive the horizontal push plate 763 to move, so that the yarn can be pushed away from the sleeve 711, and the yarn withdrawal operation is completed;

[0059] Step 4: After the yarn stops winding, the cylinder 51 is used to push the connecting kit 52 to clamp the yarn between the T-shaped sub-block 533 and the C-shaped mother block 532. At this time, one of the yarn pulling parts 53 is pushed downward by the electric guide rail 54, and the tension sensor 55 can monitor the tension data in real time until the yarn is broken, thereby completing the online collection of the yarn tension data.
