Description

Technical Field

[0001] This invention relates to the field of textile weaving, and in particular to an automated yarn threading device with an air-assisted pretreatment unit. Background Technology

[0002] In the pre-processing stage of textile weaving, warp threading is an essential step. Existing automated threading equipment on the market can automatically thread warp yarns into heddles using matching modules. However, there are common problems when the heddles are sent out of the threading station after threading. The equipment cannot automatically separate the heddles and move them to the discharge guide. Operators have to manually separate the piled-up heddles or manually adjust the pushing stroke repeatedly to barely maintain operation. This reliance on manual intervention not only disrupts the continuity of the threading process but also increases the labor intensity of operators. To solve the above problems, an automated yarn threading equipment with an air-assisted pretreatment device is proposed. Summary of the Invention

[0003] Technical problems to be solved

[0004] The purpose of this application is to provide an automated yarn threading device with an air-assisted pretreatment unit to solve the problems mentioned in the background art.

[0005] This application provides an automated threading equipment with an air-assisted pretreatment device, which adopts the following technical solution: An automated threading equipment with an air-assisted pretreatment device includes a frame, a feeding module, a pushing module, a threading module, a discharge guide rail module, a feeding assembly, and an air source assembly. The feeding assembly includes a fixed frame fixedly connected to the output end of the threading module. A bracket is fixedly connected to the upper surface of the fixed frame, and a rectangular frame is fixedly connected to the outer surface of the bracket. The rectangular frame is located above the discharge guide rail module. A lead screw is rotatably connected to the inner wall of the rectangular frame. A first servo motor is fixedly connected to the outer surface of the rectangular frame. The output shaft end of the first servo motor is fixedly connected to the rotating shaft end of the lead screw. A sleeve block is threadedly connected to the outer surface of the lead screw. An electric push rod is fixedly connected to the bottom surface of the sleeve block. An air blowing head is fixedly connected to the telescopic end of the electric push rod. A deflecting partition is fixedly connected to the bottom surface of the air blowing head. The inner wall of the deflecting partition has multiple oblique through holes communicating with the air blowing head.

[0006] By adopting the above technical solution, the material feeding component is fixed at the output end of the threading module. At the same time, the lead screw and the first servo motor drive the sleeve block and electric push rod to move along the guide direction, so that the air blowing head and the feeding baffle can accurately reach the material feeding position on the side of the heddle frame. This avoids the accumulation of a large number of heddle frames at the output end of the threading module, and also replaces the manual feeding of the heddle frames accumulated at the output end of the threading module, making it more convenient to use. In addition, multiple oblique through holes are connected to the air blowing head to assist in blowing air during the feeding process, reducing the frictional resistance between the heddle frames and avoiding material jamming. In this way, the material feeding action is no longer a simple mechanical push, but combines air assistance and controllable displacement, reducing the risk of jamming when the heddle frames are moved, thereby improving the continuity of the threading process.

[0007] Preferably, the inner wall of the rectangular frame is fixedly connected to two guide posts, and the two sides of the sleeve block are slidably sleeved on the outer surfaces of the two guide posts respectively;

[0008] By adopting the above technical solution, the guide post forms a limiting guide constraint from both sides of the sleeve block. During the movement of the sleeve block in the screw thread transmission, it always relies on the guide post to limit the movement trajectory, avoiding the situation where the sleeve block will deviate radially, get stuck or run off course due to the load force. This ensures that the power of the screw transmission can be completely converted into the linear displacement of the sleeve block, maintaining the consistency of the movement path of the subsequent air blowing head and the actuating partition, and reducing the probability of abnormal wear of parts.

[0009] Preferably, a positioning frame is fixedly connected to the bottom surface of the sleeve block, and a rotatable industrial camera is installed on the inner wall of the positioning frame;

[0010] By adopting the above technical solution, the positioning frame provides a stable installation benchmark for the industrial camera. The industrial camera can collect on-site images of the heald frame arrangement position and frame tilt status, converting the real-world situation into visual information. This allows the equipment to flexibly adjust the material feeding action according to the actual placement of the heald frame, changing the traditional material feeding mechanism's mode of rigidly pushing the heald frame with a fixed stroke. It can adapt to working conditions where the heald frame placement has slight misalignment, improving the matching degree between the material feeding action and the actual position of the heald frame.

[0011] Preferably, a worm gear is fixedly connected to the rotating shaft end of the industrial camera, a mounting bracket is fixedly connected to the bottom surface of the sleeve block, and a worm gear that meshes with the worm gear is rotatably connected to the inner wall of the mounting bracket.

[0012] By adopting the above technical solution, the worm gear and worm shaft form a meshing transmission pair based on the mounting bracket. The rotation angle of the industrial camera is locked by the transmission self-locking property of the worm gear and worm shaft themselves, preventing the industrial camera from shifting its viewing angle due to vibrations during equipment operation. At the same time, the meshing transmission of the worm gear and worm shaft can smoothly change the pitch observation angle of the industrial camera. Multi-directional adjustment of the observation angle can be achieved without the need for additional locking accessories, adapting to the image acquisition needs of frame with different thicknesses and specifications.

[0013] Preferably, a second servo motor is fixedly connected to the outer surface of the mounting bracket, and the output shaft end of the second servo motor is fixedly connected to the rotating shaft end of the worm gear;

[0014] By adopting the above technical solution, the second servo motor, as the power source of the worm gear transmission pair, can accurately output power to control the start, stop and turn of the worm, thereby switching the observation position of the industrial camera as needed, replacing the manual adjustment method of manually turning the industrial camera, and ensuring that the image acquisition point can be adjusted autonomously according to the production conditions.

[0015] Preferably, a signal processing module is fixedly connected to the upper surface of the sleeve block, and all electrical components inside the feeding assembly are electrically connected to the signal processing module;

[0016] By adopting the above technical solution, the signal processing module centrally collects the signal lines of various electrical components inside the material feeding assembly, and uniformly summarizes the position signals and image acquisition signals during the operation of the assembly. It can perform pre-processing of the acquired signals, simplify the data receiving pressure of subsequent components, and optimize the signal transmission stability of the whole machine.

[0017] Preferably, the air source assembly includes an air pump fixedly connected to the upper surface of the sleeve block, the output end of the air pump is fixedly connected to an output pipe, the output end of the output pipe is equipped with a connector, the inner wall of the connector is fixedly connected to a corrugated air pipe, and the output end of the corrugated air pipe is fixedly connected to the inside of the air blowing head.

[0018] By adopting the above technical solution, the air pump serves as the air source of the air source component. The airflow is delivered to the air blowing head through the output pipe, connector, and corrugated air pipe. The corrugated air pipe can deform and extend synchronously with the displacement of the electric push rod and the sleeve block, and the air supply will not be interrupted due to the lifting and translating of the material feeding mechanism pulling the pipeline. The connector enables the pipeline to be disassembled and connected in sections. When the pipeline is inspected or the parts are replaced, the corresponding pipe sections can be separated separately, simplifying the maintenance of the air source pipeline.

[0019] Preferably, a solenoid valve is installed on the section of the output pipe;

[0020] By adopting the above technical solution, the solenoid valve is installed on the output pipe, which can control the on / off state of the airflow inside the pipe as needed. It can flexibly start and stop the air supply according to the real situation of frame adhesion fed back by the industrial camera. It can cut off the air source output without the need for air blowing pretreatment, reduce the unnecessary loss of air source, and at the same time facilitate the independent shutdown of the corresponding branch when a single air source fails, without affecting the continuous operation of the rest of the equipment.

[0021] Preferably, the feeding module is installed at one end of the frame, the discharge guide rail module is installed at the other end of the frame, the threading module is located between the feeding module and the discharge guide rail module, and the pushing module is located in the inlet area of ​​the threading module.

[0022] By adopting the above technical solution, the frame serves as the main support for the entire machine. The feeding module, pushing module, threading module, and discharge guide rail module are arranged in sections according to the process flow. The material flows unidirectionally along the process flow of feeding, threading, shifting, and discharging. The working areas of each functional module are independent yet interconnected, avoiding the problem of cross-interference between different process working areas, and conforming to the production logic of automated continuous threading.

[0023] Preferably, a main controller is fixedly connected to the outer surface of the frame, and the electrical components inside the pushing module, threading module, material feeding assembly, and air source assembly are all electrically connected to the main controller;

[0024] By adopting the above technical solution, the main controller coordinates all electrical components of the feeding module, threading module, material feeding assembly and air source assembly, centrally issues machine action commands, and coordinates the action sequence of each module to achieve linkage control of air blowing pretreatment, servo shifting, threading operation and air source opening and closing, thereby improving the automated collaborative operation capability of the whole machine.

[0025] Beneficial effects

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] This invention provides an automated threading equipment with an air-assisted pretreatment device. By setting up a material feeding component and an air source component, during operation, a first servo motor drives a lead screw to move the sleeve block laterally. An electric push rod moves the air blowing head and the actuating partition down to the side of the heddle frame. Compressed air generated by the air pump is sent into the air blowing head through the output pipe and corrugated air pipe, and then sprayed out obliquely through the oblique through-holes opened on the actuating partition. The airflow first blows apart the heddle frames that are stuck together. Then the actuating partition pushes the heddle frames towards the discharge guide rail module. Compared with the traditional processing method that relies on manual disassembly and hard pushing of the heddle frames, the air-assisted pretreatment eliminates the problem of heddle frame adhesion, solves the problem of material feeding blockage, eliminates the step of manually pushing the heddle frames on site, ensures the orderly delivery of the heddle frames at the discharge end of the threading module, and allows the entire threading process to run continuously without interruption.

[0028] This invention provides an automated threading device with an air-assisted pretreatment unit. By incorporating a positioning frame, an industrial camera, and an angle adjustment structure consisting of a worm gear, a worm shaft, and a second servo motor at the lower part of the heald frame, the second servo motor drives the worm shaft to rotate the meshing worm gear, simultaneously changing the shooting angle of the industrial camera. The self-locking characteristic of the worm gear fixes the shooting angle. The industrial camera collects data on the actual arrangement of the heald frames and transmits it to the signal processing module. After processing, the data is transmitted to the main controller. The main controller adjusts the travel stroke of the first servo motor and the on / off timing of the solenoid valve in real time based on the heald frame placement deviation. This eliminates the fixed-stroke mechanical pushing design of the original material feeding mechanism, enabling adaptive adjustment of the material feeding and air blowing actions according to the actual working conditions of the heald frames, improving the accuracy of the material feeding position, and adapting to the production needs of various heald frame specifications.

[0029] This invention provides an automated threading equipment with an air-assisted pretreatment device. The equipment consists of a feeding module, a pushing module, a threading module, and a discharge guide rail module arranged sequentially on a frame. A central controller is used to coordinate all electrical components of the machine. In actual production, the raw material heddle frames are fed into the workstation by the feeding module. After the pushing module completes the feeding limit, the heddle frames are handed over to the threading module for threading. The semi-finished heddle frames after threading are transferred to the discharge guide rail module via a material feeding component. The entire process is controlled by the central controller to manage the start and stop sequence of each component. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0039] Example 1: An automated yarn threading device with an air-assisted pretreatment unit, referring to... Figure 1 , Figure 3 , Figure 4 and Figure 5The system includes a frame 1, a feeding module 2, a pushing module 3, a threading module 4, a discharge guide rail module 5, a material feeding assembly 6, and an air source assembly 7. The material feeding assembly 6 includes a fixed frame 601 fixedly connected to the output end of the threading module 4. A bracket 602 is fixedly connected to the upper surface of the fixed frame 601. A rectangular frame 603 is fixedly connected to the outer surface of the bracket 602. The rectangular frame 603 is located above the discharge guide rail module 5. A lead screw 604 is rotatably connected to the inner wall of the rectangular frame 603. A first servo motor 605 is fixedly connected to the outer surface of the rectangular frame 603. The output shaft end of the first servo motor 605 is fixedly connected to the rotating shaft end of the lead screw 604. A sleeve block 607 is threadedly connected to the outer surface of the lead screw 604. An electric push rod 608 is fixedly connected to the bottom surface of the sleeve block 607. An air blowing head 609 is fixedly connected to the telescopic end of the electric push rod 608. A toggle plate 610 is fixedly connected to the bottom surface of the air blowing head 609. The inner wall of the actuating partition 610 is provided with multiple oblique through holes 611 that communicate with the air blowing head 609. The material feeding assembly 6 is fixed at the output end of the threading module 4. At the same time, the lead screw 604 and the first servo motor 605 drive the sleeve block 607 and the electric push rod 608 to move along the guide direction, so that the air blowing head 609 and the actuating partition 610 can accurately reach the material feeding position on the side of the heddle frame, avoiding the accumulation of a large number of heddle frames at the output end of the threading module 4. It also replaces the manual actuation of the heddle frames accumulated at the output end of the threading module 4, making it more convenient to use. In addition, the multiple oblique through holes 611 are connected to the air blowing head 609, which assists in blowing air during the actuation process, reducing the frictional resistance between the heddle frames and avoiding material jamming. In this way, the material feeding action is no longer a simple mechanical push, but combines air assistance and controllable displacement, reducing the risk of jamming when the heddle frames are moved, thereby improving the continuity of the threading process.

[0040] Reference Figure 5 , Figure 6 and Figure 7Two guide posts 606 are fixedly connected to the inner wall of the rectangular frame 603. The two sides of the sleeve 607 are slidably fitted onto the outer surfaces of the two guide posts 606. The guide posts 606 form a limiting and guiding constraint from both sides of the sleeve 607. During the threaded transmission of the screw 604, the sleeve 607 always relies on the guide posts 606 to limit its movement trajectory, avoiding radial offset, jamming, or deviation of the sleeve 607 under load. This ensures that the transmission power of the screw 604 can be completely converted into the linear displacement of the sleeve 607, maintaining the consistency of the subsequent movement paths of the air blowing head 609 and the actuating partition 610, and reducing abnormal component movement. Regarding wear probability, a positioning frame 612 is fixedly connected to the bottom surface of the sleeve block 607. A rotatable industrial camera 613 is installed on the inner wall of the positioning frame 612. The positioning frame 612 provides a stable installation reference for the industrial camera 613. The industrial camera 613 can collect on-site images of the heald frame arrangement position and frame tilt status, converting the real-world situation into visual information. This allows the equipment to flexibly adjust the material feeding action according to the actual placement of the heald frame, changing the traditional material feeding mechanism's mode of rigidly pushing the heald frame with a fixed stroke. It can adapt to working conditions where the heald frame placement has slight misalignment, improving the matching degree between the material feeding action and the actual position of the heald frame.

[0041] Reference Figure 5 , Figure 6 and Figure 7The industrial camera 613 has a worm gear 614 fixedly connected to its rotating shaft end. A mounting bracket 615 is fixedly connected to the bottom surface of the sleeve block 607. A worm 616, meshing with the worm gear 614, is rotatably connected to the inner wall of the mounting bracket 615. The worm gear 614 and worm 616 form a meshing transmission pair based on the mounting bracket 615. The rotation angle of the industrial camera 613 is locked by the self-locking property of the worm gear itself, preventing the viewing angle of the industrial camera 613 from shifting due to vibrations during equipment operation. Simultaneously, the worm gear meshing transmission can smoothly change the pitch angle of the industrial camera 613, achieving multi-directional adjustment of the viewing angle without the need for additional locking accessories, adapting to the image acquisition needs of frame sizes with different thicknesses. A second servo motor 617 is fixedly connected to the outer surface of the mounting bracket 615. The output shaft end of the second servo motor 617... The second servo motor 617, fixedly connected to the shaft end of the worm gear 616, serves as the power source for the worm gear transmission pair. It can precisely output power to control the start, stop, and direction of the worm gear 616, thereby switching the observation position of the industrial camera 613 as needed. This replaces the manual adjustment method of manually turning the industrial camera 613, ensuring that the image acquisition point can be adjusted autonomously according to the production conditions. The upper surface of the sleeve block 607 is fixedly connected to the signal processing module 618. All electrical components inside the material feeding assembly 6 are electrically connected to the signal processing module 618. The signal processing module 618 centrally collects the signal lines of various electrical components inside the material feeding assembly 6, and uniformly summarizes the position signals and image acquisition signals during the operation of the assembly. It can perform pre-processing of the acquired signals, simplify the data receiving pressure of subsequent assemblies, and optimize the signal transmission stability of the whole machine.

[0042] Example 2: An automated yarn threading device with an air-assisted pretreatment unit, referring to... Figure 1 , Figure 6 and Figure 7The air source assembly 7 includes an air pump 701 fixedly connected to the upper surface of the sleeve block 607. The output end of the air pump 701 is fixedly connected to an output pipe 702. A connector 703 is installed at the output end of the output pipe 702. A corrugated air pipe 704 is fixedly connected to the inner wall of the connector 703. The output end of the corrugated air pipe 704 is fixedly connected to the inside of the air blowing head 609. The air pump 701 serves as the air supply source for the air source assembly 7. The airflow is delivered to the air blowing head 609 via the output pipe 702, connector 703, and corrugated air pipe 704. The corrugated air pipe 704 can deform and extend synchronously with the displacement of the electric push rod 608 and the sleeve block 607, and will not be affected by the lifting of the feeding mechanism. The displacement and pulling of the pipeline caused an interruption in the air supply. The connector 703 enables the detachable connection of the pipeline sections. During subsequent pipeline maintenance and parts replacement, the corresponding pipeline sections can be separated individually, simplifying the maintenance of the air source pipeline. A solenoid valve 705 is installed on the pipeline section of the output pipe 702. The solenoid valve 705 is arranged on the output pipe 702 pipeline and can control the on / off state of the airflow inside the pipeline as needed. It can flexibly start and stop the air supply based on the real-time situation of frame adhesion fed back by the industrial camera 613. The air source output can be cut off without the need for air blowing pretreatment, reducing the unnecessary loss of the air source. At the same time, it is convenient to independently shut down the corresponding branch when a single air source fails, without affecting the continuous operation of the rest of the equipment.

[0043] Reference Figure 1 and Figure 2 The feeding module 2 is installed at one end of the frame 1, the discharge guide rail module 5 is installed at the other end of the frame 1, the threading module 4 is located between the feeding module 2 and the discharge guide rail module 5, and the pushing module 3 is located in the inlet area of ​​the threading module 4. The frame 1 serves as the supporting base of the entire machine, and the feeding module 2, pushing module 3, threading module 4, and discharge guide rail module 5 are arranged in sections according to the process flow. The material flows unidirectionally along the process flow of feeding, threading, shifting, and discharging. The working areas of each functional module are independent of each other but connected in process, avoiding the overlap of different process working areas. To address the issue of cross-interference and align with the production logic of automated continuous threading, a central controller 8 is fixedly connected to the outer surface of the frame 1. The electrical components inside the pushing module 3, threading module 4, material feeding assembly 6, and air source assembly 7 are all electrically connected to the central controller 8. The central controller 8 coordinates all electrical components of the pushing module 3, threading module 4, material feeding assembly 6, and air source assembly 7, centrally issues machine operation commands, and coordinates the timing of actions of each module to achieve linkage control of air blowing pretreatment, servo shifting, threading operation, and air source opening and closing, thereby improving the automated collaborative operation capability of the entire machine.

[0044] It should be noted that the feeding module 2, pushing module 3, threading module 4, and discharge guide rail module 5 of this application are all conventional functional modules used in automated threading equipment in the field. The threading module 4 typically includes a threading hook, a yarn separating mechanism, and a crank-slider mechanism that drives the threading hook to reciprocate. Its specific structure and working principle have been widely described in the automatic threading machine technology disclosed in the field. The discharge guide rail module 5 can be composed of a set of parallel slide rails or rollers for the heald frame pushed by the material feeding component 6. The above modules are not the inventive point of this application. The core improvement of this application lies in the material feeding component 6 and its matching air source component 7 and visual positioning structure. These improvements can directly solve the problem that the heald frames at the output end of existing threading equipment are prone to accumulation and require manual intervention. Therefore, this specification will not label or describe the non-essential specific components inside the feeding module 2, pushing module 3, threading module 4, and discharge guide rail module 5 one by one. Those skilled in the art can fully realize the basic functions of the above modules based on the existing technology, which will not lead to insufficient disclosure of the technical solution.

[0045] The implementation principle of this application embodiment is as follows: First, the operator places the heald frames to be processed in batches on the feeding module 2. The feeding module 2 is located at one end of the frame 1. The pushing module 3 is arranged in the inlet area of ​​the threading module 4, responsible for pushing the heald frames sent out by the feeding module 2 one by one into the working position of the threading module 4. The threading module 4 performs the core action of the warp yarn passing through the heald eye. When its output end completes one threading, the heald frame with the warp yarn already threaded needs to be removed in time to make room for the next heald frame. At this time, the material feeding component 6 fixed at the output end of the threading module 4 starts to intervene. The fixing frame 601 and the bracket 602 in the material feeding component 6 support the rectangular frame 603 above the discharge guide rail module 5. The main controller 8 sends signals to the first servo motor 60 according to the preset timing. 5. The electric push rod 608 issues a command. First, the electric push rod 608 moves the air blowing head 609 and the actuating partition 610 upwards. Then, the first servo motor 605 drives the lead screw 604 to rotate. The sleeve 607, which is threaded to the lead screw 604, moves smoothly laterally along the two guide posts 606. The guide posts 606 constrain the movement trajectory of the sleeve 607 from both sides to prevent it from swaying or jamming due to uneven force. When the sleeve 607 moves to the side position of the target heald frame, the electric push rod 608 extends, driving the air blowing head 609 and the actuating partition 610 to descend to the gap between the heald frames. At the same time as the descent, the air pump 701 in the air source assembly 7 starts to work. Compressed air is sent into the air blowing head through the output pipe 702, the connector 703 and the corrugated air pipe 704. The airflow enters the air head 609 and is then ejected from multiple oblique through-holes 611 on the actuating baffle 610. These oblique airflows first act on the contact surfaces of adjacent heddle frames, blowing away any slight adhesion between the two heddle frames that may be due to static electricity or lint. After the airflow pretreatment is completed, the actuating baffle 610 continues to move downwards, separating the heddle frames accumulated at the output end of the threading module 4. Then, the first servo motor 605 is activated to push the actuating baffle 610 forward, smoothly pushing the heddle frames to the outside of the discharge guide rail module 5, allowing them to slide along the rail to the next station. To further improve the accuracy of material feeding, a positioning frame 612 and an industrial camera 613 are also installed at the bottom of the sleeve block 607. The rotating shaft end of the industrial camera 613 is connected to a worm gear 614, and a mounting bracket 615 is also installed. The worm gear 616 meshes with the worm wheel 614 and is driven by the second servo motor 617. When the shooting angle needs to be adjusted, the main controller 8 controls the second servo motor 617 to drive the worm gear 616 to rotate, and the worm wheel 614 rotates slowly accordingly, thereby changing the pitch angle of the industrial camera 613. Because the worm gear pair has a self-locking characteristic, the viewing angle of the industrial camera 613 will be firmly locked after the adjustment is completed, and it will not deviate due to equipment vibration. The industrial camera 613 collects the arrangement and skew of the lower heald frame and transmits the image signal to the signal processing module 618 on the upper surface of the sleeve block 607. After the signal processing module 618 performs preliminary processing of the image data, it reports it to the main controller 8. The main controller 8 determines the position deviation of the heald frame based on the actual observed position.The travel distance of the first servo motor 605 is dynamically corrected, and the opening and closing of the solenoid valve 705 are determined. Throughout the process, the corrugated air hose 704 can freely extend and retract with the raising and lowering of the electric push rod 608, preventing blockage of the air passage due to repeated bending.
