Description

Technical Field

[0001] The invention relates to the technical field of jacquard creels, in particular to a warp knitting jacquard intelligent creel and a control system thereof. Background Art

[0002] The traditional jacquard creel design for warp knitting is a fixed structure, which makes yarn changes inconvenient. Each yarn change requires significant operator time and effort, increasing labor costs and reducing production efficiency. More importantly, this design makes yarn changes extremely inconvenient, increasing operational difficulty and placing higher demands on the knitting process. Furthermore, the fixed creel design makes yarn changes extremely tedious, further hindering the smooth progress of knitting operations. Furthermore, the traditional creel utilizes a passive yarn feeding system, which lacks the ability to actively adjust the yarn during the knitting process, placing extremely high demands on the knitting process. This passive yarn feeding system can easily cause yarn elasticity loss or irreversible stretching, severely impacting the quality and performance of the fabric. Therefore, the traditional jacquard creel for warp knitting is insufficient to meet the demands of the modern textile industry for efficient and high-quality production, and is unable to meet the complex and ever-changing production process requirements. Traditional warp knitting jacquard creels are unable to handle highly elastic and special yarns, and are unable to meet the modern textile industry's demand for efficient and high-quality production. Summary of the Invention

A tension control device is installed in each yarn hanging rod. Each tension control device installed in the yarn hanging rod is electrically connected to the yarn rod driving device of the corresponding yarn hanging rod to independently control the rotation speed of each yarn hanging rod.

[0005] In some embodiments, the tension control device includes at least one stress retaining spring disposed through the surface of the yarn hanging rod, and a piston plate, an air pressure sensor, and a control component disposed inside the yarn hanging rod.

[0011] In some embodiments, the moving component includes a drive motor, a wheel frame, a sliding wheel, and a track. The drive motor is installed at the side end of the wheel frame, and the output end of the drive motor is connected to the sliding wheel. The sliding wheel displaces along the track laying direction, and the yarn frame is actively displaced by the moving component.

The sensor measures the measurement data and feeds the measurement data back to the main control module. The main control module analyzes and compares the measurement data with its stored initial data and issues control instructions to the yarn rod control module.

[0013] In some embodiments, when the measured data is less than the initial data, the overall control module sends a command to reduce the rotation speed to the yarn rod control module; When the measured data is greater than the initial data, the overall control module sends an instruction to increase the rotation speed to the yarn rod control module.

[0022] like Figures 1-13 As shown, the present invention provides a warp knitting jacquard intelligent creel, comprising a creel frame 1, a yarn hanging rod 4, a yarn rod driving device 5, and a tension control device 6. A plurality of yarn hanging rods 4 are arranged on the creel frame 1, and each yarn hanging rod 4 is independently controlled to rotate by the yarn rod driving device 5. A tension control device 6 is installed in the yarn hanging rod 4, and each tension control device 6 installed in the yarn hanging rod 4 is electrically connected to the yarn rod driving device 5 of the corresponding yarn hanging rod 4, and independently controls the rotation speed of each yarn hanging rod 4.

[0023] According to some embodiments of the present invention, optionally, the tension control device 6 includes at least one stress retaining spring 61 penetrating the surface of the yarn hanging rod 4 and a piston plate 60, an air pressure sensor 62, and a control component 601 arranged inside the yarn hanging rod 4.

[0024] According to some embodiments of the present invention, optionally, one end of the stress retaining spring 61 is fixedly connected to the surface of the yarn hanging rod 4, and the other end is a movable end 611 connected to the piston plate 60 inside the yarn hanging rod 4; an air pressure sensor 62 is also provided in the internal enclosed space 40 of the yarn hanging rod 4 isolated by the piston plate 60, and the air pressure sensor 62 is electrically connected to the control component 601 connected to the piston plate 60 and the yarn rack drive device.

[0025] Multiple stress retaining springs 61 are provided, for example, two stress retaining springs 61 are provided, distributed on two sides of the same position on the yarn hanging rod 4. The piston plate 60 is connected to the movable ends 611 of the stress retaining springs 61 on the upper and lower sides via a connector 602. The multiple stress retaining springs 61 ensure that the yarn bobbin 10 will not easily come loose after being installed on the yarn hanging rod 4, and also facilitate the replacement of the yarn bobbin 10 on the yarn hanging rod 4. The yarn rod drive device 5 is often an electric motor, and the control component 601 is often a pneumatic rod. A Hall effect sensor 63 can also be provided inside the yarn hanging rod 4 as needed to detect the speed of rotation of the yarn hanging rod 4.

[0026] According to some embodiments of the present invention, optionally, several wire collecting plates 3 are installed on the creel frame 1.

[0027] According to some embodiments of the present invention, optionally, a limit plate 7 is installed at the back end of the yarn hanging rod 4, and an antistatic coating 41 is coated on the surface of the yarn hanging rod 4.

[0028] The function of the limit plate 7 is to support the back side of the yarn tube 10. The thickness of the limit plate 7 is selected according to the needs. The surface of the yarn hanging rod 4 is coated with an anti-static coating 41. The anti-static coating 41 can effectively reduce the static electricity accumulation caused by the friction between the yarn and the yarn hanging rod 4, and avoid the yarn hairiness, entanglement or breakage problems caused by electrostatic adsorption.

[0029] According to some embodiments of the present invention, optionally, a moving assembly 2 is further included which is installed at the bottom end of the creel frame 1 , and the creel frame 1 is actively or passively displaced by the moving assembly 2 .

[0030] According to some embodiments of the present invention, optionally, the moving component 2 includes a sliding wheel 21 and a track 22. The sliding wheel 21 is rotatably installed at the bottom end of the creel frame 1, and the sliding wheel 21 is displaced along the laying direction of the track 22. The creel frame 1 is passively displaced by the moving component 2.

[0031] According to some embodiments of the present invention, optionally, the moving component 2 includes a drive motor 23, a wheel frame 24, a sliding wheel 21, and a track 22. The drive motor 23 is installed at the side end of the wheel frame 24, and the output end of the drive motor 23 is connected to the sliding wheel 21. The sliding wheel 21 is displaced along the laying direction of the track 22, and the yarn rack frame 1 is actively displaced through the moving component 2.

[0032] The warp knitting jacquard intelligent creel structure in the present invention is more streamlined than the traditional creel, so that the moving component 2 moves the creel frame 1 out of the initial position, and there is no complex structure blocking the yarn hanging surface at the side end of the creel frame 1, such as: the tension rod in the traditional creel. Based on the creel structure in the present invention, the yarn hanging operation is more convenient; at the same time, since the creel structure is more streamlined, the maintenance cost is also lower.

[0033] With the development of robot technology, the yarn hanging operation can be replaced by a yarn hanging robot 8 instead of manual labor. Compared with manual yarn hanging, the yarn hanging robot 8 is more accurate and skilled in hanging yarn, avoiding the possible damage of the yarn during the hanging process and ensuring the quality of the yarn. The common yarn hanging robot 8 can control the yarn hanging mechanical arm 81 to operate the yarn hanging after scanning and identifying the yarn hanging rod 4 through the visual recognition device 82. Figure 10 .

[0034] The present invention also provides a warp knitting jacquard intelligent creel control system, comprising a general control module 100, a yarn rod control module 200, and a tension control module 300, wherein the general control module 100 is electrically connected to the yarn rod control module 200 and the tension control module 300, respectively, and the tension control module 300 is electrically connected to the yarn rod control module 200; The tension control module 300 monitors the data changes in the yarn hanging rod 4 through a sensor. The sensor measures the measurement data and feeds the measurement data back to the main control module 100. The main control module 100 analyzes and compares the measurement data with the initial data stored therein. The main control module 100 analyzes and compares the measurement data with the initial data stored therein and issues a control instruction to the yarn rod control module 200. According to some embodiments of the present invention, optionally, when the measured data is less than the initial data, the overall control module 100 issues a command to reduce the rotation speed to the yarn rod control module 200; When the measured data is greater than the initial data, the main control module 100 sends an instruction to increase the rotation speed to the yarn rod control module 200.

[0035] According to some embodiments of the present invention, optionally, the sensor is an air pressure sensor 62 .

[0036] According to some embodiments of the present invention, optionally, a movement control module 400 is further included, and the main control module 100 is electrically connected to the movement control module 400; After receiving an instruction from an external controller or a user interface on the warp knitting jacquard intelligent creel, the main control module 100 starts the movement control module 400, and the movement control module 400 executes the instruction to control the warp knitting intelligent creel to move from the initial position to the yarn changing position.

[0037] Example 1 like Figures 1-8As shown, this embodiment provides a warp knitting jacquard intelligent creel, including a creel frame 1, a yarn hanging rod 4, a yarn rod drive device 5, a tension control device 6, and a yarn collecting plate 3. A plurality of yarn hanging rods 4 are arranged on the creel frame 1, and each yarn hanging rod 4 is independently controlled to rotate by the yarn rod drive device 5. A tension control device 6 is installed in each yarn hanging rod 4. Each tension control device 6 installed in the yarn hanging rod 4 is electrically connected to the yarn rod drive device 5 of the corresponding yarn hanging rod 4. The rotation speed of each yarn hanging rod 4 is independently controlled by the tension control device 6 and the yarn rod drive device 5. The creel frame 1 consists of a transverse frame 11 and a longitudinal frame 12. The transverse frame 11 and the longitudinal frame 12 can be assembled together by welding or screw locking.

[0038] The tension control device 6 includes at least one stress retaining spring 61 which is arranged through the surface of the yarn hanging rod 4, and a piston plate 60, an air pressure sensor 62, and a control component 601 which are arranged inside the yarn hanging rod 4; one end of the stress retaining spring 61 is fixedly connected to the surface of the yarn hanging rod 4, and the other end is a movable end 611 which is connected to the piston plate 60 inside the yarn hanging rod 4; an air pressure sensor 62 is also arranged in the internal enclosed space 40 of the yarn hanging rod 4 isolated by the piston plate 60, and the air pressure sensor 62 is electrically connected to the control component 601 connected to the piston plate 60 and the yarn frame drive device; a limit plate 7 is installed at the back end of the yarn hanging rod 4, and the surface of the yarn hanging rod 4 is coated with an anti-static coating 41.

[0039] When the warp knitting jacquard intelligent yarn frame in this embodiment is used, the yarn bobbin 10 is installed on the yarn hanging rod 4, and the stress retaining spring 61 on the yarn hanging rod 4 is used to clamp and limit the yarn bobbin 10. The yarn on the yarn bobbin 10 is first pulled to the ceramic yarn guide eye 31 on the wire collecting plate 3 for guidance, and then pulled to the loom; the yarn on the yarn bobbin 10 is directly guided by the ceramic yarn guide eye 31 on the wire collecting plate 3, and the path of the yarn being pulled to the loom becomes a straight line, which reduces the offset, makes the yarn delivery more uniform, and avoids the problem of uneven tension caused by bending; when the loom pulls the yarn during weaving, the yarn bobbin 10 will be displaced, and the stress retaining spring 61 arranged on the surface of the yarn hanging rod 4 will be subjected to the pressure exerted by the yarn bobbin 10, so that the data of the air pressure sensor 62 will change, and the speed of the yarn rod drive device 5 will be fed back and changed to adjust the tension of the yarn.

[0040] When the stress retaining spring 61 is clamped to the yarn bobbin 10, it assumes an arched bridge shape. The shape of the stress retaining spring 61 is adjusted by controlling the displacement of the piston plate 60 via the control assembly 601. The piston plate 60 directly or indirectly controls the displacement of the movable end 611 of the corresponding stress retaining spring 61. The closer the movable end 611 of the stress retaining spring 61 is to the fixed end 612, the more pronounced the arching and curvature of the stress retaining spring 61. Because the movable end 611 of the stress retaining spring 61 is displaceable, a sliding opening is typically provided on the surface of the yarn hanging rod 4 to match it. A sealing sheet is also provided on the movable end 611 of the stress retaining spring 61 that extends into the interior of the yarn hanging rod 4. The area of the sealing sheet is larger than the opening of the sliding opening, thereby enhancing the sealing effect of the sliding opening.

[0041] Example 2 like Figure 1 As shown, this embodiment provides a warp knitting jacquard intelligent creel. The difference between this embodiment and embodiment 1 is that the warp knitting jacquard intelligent creel in this embodiment also includes a moving component 2 installed at the bottom end of the creel frame 1. The creel frame 1 is passively displaced by the moving component 2, which can be understood as moving the creel in cooperation with the sliding wheel 21 by manual pulling.

[0042] Specifically, the moving assembly 2 includes a sliding wheel 21 and a track 22 . The sliding wheel 21 is rotatably mounted on the bottom end of the creel frame 1 . The sliding wheel 21 moves along the laying direction of the track 22 , and the creel frame 1 is passively displaced by the moving assembly 2 .

[0043] Example 3 like Figure 9 As shown, this embodiment provides a warp knitting jacquard intelligent creel. The difference between this embodiment and embodiment 2 is that: in this embodiment, the creel frame 1 is actively displaced by the moving component 2, which can be understood as moving the creel by controlling the sliding wheel 21 through a motor.

[0044] Specifically, the moving component 2 includes a drive motor 23, a wheel frame 24, a sliding wheel 21, and a track 22. The drive motor 23 is installed at the side end of the wheel frame 24. The output end of the drive motor 23 is connected to the sliding wheel 21. The sliding wheel 21 moves along the laying direction of the track 22, and the yarn rack frame 1 is actively displaced through the moving component 2.

[0045] The two end portions of the track 22 are the use position and the yarn changing position of the yarn rack, respectively. The moving distance is limited by the track 22. If a driving motor 23 is used to drive the sliding wheel 21, a laser ranging sensor can be used to detect the outer pulling distance of the yarn rack. When the maximum stroke is reached, the driving motor 23 is turned off.

[0046] The bottom end of the warp knitting jacquard intelligent creel in this embodiment is driven by a drive motor 23. When in use, the drive motor 23 drives the sliding wheel 21 to rotate, and the sliding wheel 21 at the bottom end of the creel frame 1 moves along the laying direction of the track 22, and the yarn tube 10 placed on the yarn hanging rod 4 is replaced manually.

[0047] The warp knitting jacquard intelligent creel in Examples 1-3 is not limited to being set up in one layer, but can be set up in multiple layers; when two layers are selected, the creel frame 1 of the upper layer is supported by the frame 9. The yarn hanging operation is not limited to manual yarn hanging, and the yarn hanging robot 8 can also be used to operate the yarn hanging. At least one yarn hanging mechanical arm 81 is set on the yarn hanging robot 8, and the yarn hanging mechanical arm 81 recognizes the hanging yarn through the visual recognition device 82; in order to adapt to the multi-layer yarn hanging operation, the yarn hanging robot 8 can hang the yarn by extending the yarn hanging mechanical arm 81, and only a hollow structure 91 is provided on the frame 9 of the second layer to cooperate, such as Figure 11 shown.

[0048] Example 4 like Figure 12 As shown, this embodiment provides a warp knitting jacquard intelligent creel control system, including a main control module 100, a yarn rod control module 200, and a tension control module 300. The main control module 100 is electrically connected to the yarn rod control module 200 and the tension control module 300, respectively, and the tension control module 300 is electrically connected to the yarn rod control module 200; The tension control module 300 monitors the data changes in the yarn hanging rod 4 through the air pressure sensor 62. The air pressure sensor 62 measures the measurement data and feeds the measurement data back to the main control module 100. The main control module 100 analyzes and compares the measurement data with the initial data stored therein. When the measured data is less than the initial data, the main control module 100 sends a command to reduce the rotation speed to the yarn rod control module 200; When the measured data is greater than the initial data, the main control module 100 sends an instruction to increase the rotation speed to the yarn rod control module 200.

[0049] When the warp knitting jacquard intelligent yarn frame is used in conjunction with a loom for weaving, when the yarn feeding speed of the yarn frame cannot keep up with the weaving speed of the loom, the loom pulls the yarn during weaving, causing the yarn tube 10 to be displaced, and the stress retaining spring 61 arranged on the surface of the yarn hanging rod 4 is subjected to the pressure exerted by the yarn tube 10, causing the data monitored by the air pressure sensor 62 in the yarn hanging rod 4 to change, that is, to differ from the initial data; the main control module 100 analyzes and processes the data, and finally feeds back to the yarn rod control module 200, which executes after receiving the instruction to reduce or increase the speed.

[0050] Example 5 like Figure 13As shown, this embodiment provides a warp knitting jacquard intelligent creel control system. The warp knitting jacquard intelligent creel control system in this embodiment further includes a mobile control module 400. The main control module 100 is electrically connected to the mobile control module 400. After receiving an instruction from an external controller or a user interface on the warp knitting jacquard intelligent creel, the main control module 100 starts the movement control module 400, and the movement control module 400 executes the instruction to control the warp knitting intelligent creel to move from the initial position to the yarn changing position.

[0051] In actual application, the warp knitting jacquard intelligent creel control system in this embodiment is mostly adapted for application to the warp knitting jacquard intelligent creel in Example 3, that is, a moving component 2 is set at the bottom end of the creel frame 1, and the moving component 2 includes a drive motor 23. After the mobile control module 400 is started, the drive motor 23 drives the sliding wheel 21 to move along the laying direction of the track 22, that is, the overall movement of the creel is adjusted.

[0052] Example 6 This embodiment provides a warp knitting jacquard intelligent creel control system. Based on Example 4, in order to improve the use effect of the control system in the application of warp knitting jacquard intelligent creel, the main control module 100 detects whether the yarn rod drive device 5 is turned on. When the yarn rod drive device 5 is turned on, the control component 601 is in a locked state and does not control the displacement of the piston plate 60. At this time, the control component 601 will not change the position of the piston plate 60, will not change the distance between the movable end 611 and the fixed end 612 of the stress retaining spring 61, and will not change the arch of the stress retaining spring 61; when the yarn rod drive device 5 is closed, the control component 601 is unlocked, and the control system changes the position of the piston plate 60 through the control component 601, indirectly changes the distance between the movable end 611 and the fixed end 612 of the stress retaining spring 61, and adjusts the arch of the stress retaining spring 61, so that the yarn tube 10 is moved out of or loaded into the yarn hanging rod 4.

[0053] Once the control system in this embodiment detects that the yarn rod driving device 5 is in the on state, the stress retaining spring 61 cannot be adjusted. That is, when the yarn rod driving device 5 controls the yarn bobbin 10 on the yarn hanging rod 4 to feed the yarn, the installed yarn bobbin 10 cannot be removed by adjusting the stress retaining spring 61.

[0054] Example 7 This embodiment provides a warp knitting jacquard intelligent creel control system. This embodiment is based on Example 5. The main control module 100 detects whether the yarn rod drive device 5 is turned on. When the yarn rod drive device 5 is turned off, the drive motor 23 is unlocked, and the control system links the drive motor 23 to start. The moving component 2 at the bottom end of the target creel is driven by the drive motor 23 to pull the target creel as a whole outward to the preset yarn changing position.

[0055] Once the control system in this embodiment detects that the yarn rod drive device 5 is in the on state, the drive motor 23 cannot be used to control the displacement of the target yarn rack for yarn replacement; on the contrary, the drive motor 23 first controls the target yarn rack to move outward, which facilitates the subsequent replacement of the yarn bobbin 10.

[0056] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
