[0002] Although the conventional full computer hosiery machine on the market has the functions of hosiery knitting and toe sewing, there are many problems in the actual production process. When the existing hosiery machine continuously produces hosiery, workers need to conduct manual sampling inspection at regular intervals to judge the product quality, and adjust the hosiery state parameters according to the detection results. Since one worker usually needs to manage 5-20 hosiery machines at the same time, the detection time of hosiery is highly uncertain. In addition, all the produced hosiery is collected in a collection frame, and when quality problems are found, it is difficult to accurately locate the production interval of the problem hosiery. This detection method not only increases the workload of workers, but also makes it difficult to reflect the trend change of quality problems from the detection results of individual hosiery quality problems, which is not conducive to targeted optimization of hosiery production parameters. How to realize the regular automatic sampling detection of hosiery and accurately reflect the overall production quality status is a technical problem to be solved in the field. SUMMARY

[0024] The technical solutions in the present application will be described clearly and completely in the present application in combination with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. The components of the present application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application. It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] In the prior art, the full computerized hosiery machine realizes continuous production through automatic knitting and sewing head functions, and the finished hosiery is collected to a unified container through a pneumatic pipeline. Since one operator needs to manage multiple devices at the same time, the sampling detection has time randomness, which makes it difficult to trace the quality abnormal interval. The traditional manual sampling method needs to frequently interrupt the device operation, and cannot establish the corresponding relationship between the detection samples and the production batches, affecting the timeliness of parameter adjustment.

[0026] In order to solve the above problems, the person skilled in the art pays attention to how to realize regular sampling without disturbing continuous production. The core contradiction is to keep the falling channel unobstructed and periodically intercept the detection samples. By analyzing the production rhythm characteristics, it is found that the sampling period can be set based on time or output, so that the detection samples are uniformly distributed in different production stages. Further considering the feasibility of mechanical structure, a movable carrier needs to be designed to temporarily accept the falling material in a certain period, and then quickly reset to avoid hindering normal discharge.

[0027] Therefore, the application provides a hosiery machine for detecting socks according to frequency, which comprises a hosiery machine 7, a sock suction device arranged on the side of the hosiery machine 7, a first air pipe 1 and a second air pipe 2 of the sock suction device, and an air pump for providing air suction force for sucking socks, and a feeding cylinder 3 arranged between the first air pipe 1 and the second air pipe 2 and communicating with the first air pipe 1 and the second air pipe 2, characterized in that the hosiery machine 7 is provided with a feeding tray 5 for detecting socks according to frequency on the side of the hosiery machine 7, the feeding tray 5 is controlled to move to below the feeding cylinder 3 to obtain the socks to be detected, and then the feeding tray 5 is driven to move away from below the feeding cylinder 3, without affecting the output of the socks from the feeding cylinder to the hosiery machine; the frequency for detecting the socks according to frequency is the production quantity frequency of the socks or the production time frequency of the hosiery machine; the production quantity frequency of the socks is that the socks are detected once for each set production quantity, and the production time frequency of the hosiery machine is that the socks are detected once for each set production time. The feeding tray 5 controlled to move is arranged on the side of the hosiery machine, and the feeding tray 5 moves to below the feeding cylinder to obtain the detection sample according to the preset frequency. The frequency parameter can be selected as the production quantity or the time interval, and when the set threshold value is reached, the driving device is started to make the feeding tray receive the current feeding, and then the feeding tray is immediately removed to restore the smooth passage.

[0028] The frequency detection mechanism according to frequency refers to the control logic for triggering the sampling action according to the production progress. Specifically, a counter can be used to record the production quantity or a timer can be used to monitor the production time length, and a driving signal is sent when the value reaches the set threshold value. This mechanism ensures that the sampling interval meets the quality management requirements, so that the detection sample covers different production stages. The feeding tray refers to a container device for carrying the detection sample, which can specifically adopt a tray structure supported by a metal frame, and the size of the tray structure is adapted to the outlet of the feeding cylinder. The component is in an avoiding position during a non-sampling period, so as to avoid interfering with the normal feeding path. The driving device refers to an actuator for controlling the displacement of the feeding tray, which can specifically adopt a pneumatic slide rail or a rotating arm structure. The device drives the feeding tray to complete the switching between the sampling position and the avoiding position in response to the frequency signal, so as to ensure that the action is fast and accurate.

[0029] Specifically, when the socks with finished toe are sucked into the feeding cylinder through the pneumatic pipeline, the control system continuously monitors the production data. After the preset production quantity or time is reached, the driving device pushes the feeding tray to be directly below the feeding cylinder, at this time, the falling socks fall into the feeding tray instead of the normal collection frame. After the sampling is completed, the driving device immediately moves the feeding tray out of the feeding area, and the subsequent socks continue to normally fall into the collection frame. The operator regularly checks the sample quality in the feeding tray, and locates the production period or the production interval corresponding to the quality fluctuation by analyzing the detection results of different sampling periods.

[0030] Compared with the prior art, the traditional method relies on manual random sampling of mixed batches of collected samples, and cannot establish the corresponding relationship between the detection results and the production period. The mechanical sampling triggered by time sequence or production in the present scheme makes each detection sample have a clear production stage mark, which provides data support for parameter optimization. At the same time, the automatic sampling process avoids the influence of manual intervention on production efficiency.

[0031] Through the technical solution, the application realizes the association recording of periodic automatic sampling and production data, so that the quality anomaly can be traced to a specific production interval. The operator accurately judges the equipment state change trend by analyzing the detection samples in time sequence or yield distribution, and adjusts the process parameters accordingly. The scheme improves the quality monitoring accuracy while maintaining continuous production and reduces the frequency of manual inspection.

[0032] The application further proposes a driving device including a tray horizontal driving device or a tray rotating driving device. The tray horizontal driving device includes a sliding cylinder 16 connected with a guide rail 17, and the sliding cylinder 16 is connected with the tray 5. The tray rotating driving device includes a rotating cylinder 11, and the rotating cylinder 11 is connected with the tray 5 through a rotating arm 12.

[0033] The tray horizontal driving device refers to a mechanism for realizing the horizontal movement of the tray through the driving of the cylinder. Specifically, the sliding cylinder can be used in cooperation with the guide rail to realize the horizontal movement of the tray. The sliding cylinder moves along the guide rail to drive the tray to move in the horizontal direction to the lower side of the dropping cylinder or to reset. The tray rotating driving device refers to a mechanism for realizing the rotating displacement of the tray through the driving of the cylinder. Specifically, the rotating cylinder can be used in cooperation with the rotating arm to realize the rotating displacement of the tray. The rotating cylinder drives the rotating arm to rotate around the shaft, and then drives the tray to rotate along the rotating track to approach or move away from the lower side of the dropping cylinder.

[0034] Specifically, when the tray horizontal driving device works, the sliding cylinder pushes the tray to move horizontally along the guide rail to the lower side of the dropping cylinder, so that the tray accurately catches the falling socks to be detected. Then, the cylinder drives the tray to reset to avoid hindering the normal falling of the subsequent socks into the collection frame. When the tray rotating driving device works, the rotating cylinder drives the rotating arm to drive the tray to rotate around the fixed shaft to the lower side of the dropping cylinder. After completing the material receiving, the tray is reset in the reverse direction. The two driving modes can be flexibly selected according to the space limitation of the production environment or the detection requirements. For example, in a narrow space, the rotating driving is preferred to reduce the occupied area, or in a scene requiring fast linear movement, the horizontal driving is used.

[0035] Through the technical solution, the application realizes the accurate positioning of the tray during the material receiving and resetting process, ensures the accurate acquisition of the detection sample and does not affect the normal production process, and at the same time simplifies the driving structure and reduces the equipment maintenance cost.

[0036] The application further proposes that the metal frame 15 is fixedly connected with the rotating arm 12 or the sliding cylinder 16.

[0037] The metal frame refers to a supporting structure wrapped outside the tray, which can be made of stainless steel or aluminum alloy, and is used to quickly place or take out the tray. The fixed connection refers to the rigid connection between the metal frame and the rotating arm or the sliding cylinder, which can be achieved by bolt fastening, welding or buckle structure, to ensure that the tray maintains a stable motion trajectory under the drive of the driving device.

[0038] Specifically, the metal frame is designed in a ring or U-shaped structure, tightly fitted around the outer periphery of the tray, and connected to the driving part of the rotating arm or the sliding cylinder through a fixed point. When the driving device drives the rotating arm or the sliding cylinder to move, the metal frame uniformly transmits the driving force to the tray, avoiding tilting or shaking of the tray due to uneven local stress. For example, in the tray horizontal driving device, the sliding cylinder pushes the tray to translate along the guide rail through the metal frame; in the tray rotating driving device, the rotating arm drives the tray to rotate around the shaft through the metal frame. The rigid support of the metal frame can prevent the tray from deforming during frequent start-stop or high-speed motion, thereby ensuring the positioning accuracy when detecting socks.

[0039] Through the above technical solution, the present application solves the problem of deformation or difficulty in taking and placing the tray during frequent motion, ensuring that the detected socks can accurately fall into the specified position of the tray, while reducing the detection error and equipment maintenance frequency caused by unstable mechanical structure.

[0040] The present application further proposes that the tray horizontal driving device or the tray rotating driving device is connected to the installation support 6, which is connected to the hosiery machine 7 and the material dropping cylinder 3. The material dropping cylinder 3 is a conical barrel structure with a smaller top than a bottom. The top side of the conical barrel structure is connected to the first air pipe 1, and the bottom side of the conical barrel structure is connected to the second air pipe 2.

[0041] The installation support refers to a connecting component for fixing the driving device and the hosiery machine and the material dropping cylinder, which can be realized by a metal frame or a welded structural member. Its function is to rigidly connect the driving device and the hosiery machine body, ensuring the stability of the tray motion trajectory. The conical barrel structure refers to a cylindrical container with a cross-section in the shape of a narrow top and a wide bottom. It can be made of stainless steel or plastic material. The top narrowing design is beneficial to the formation of negative pressure adsorption by gas flow, and the bottom flaring structure facilitates the natural falling of socks. The connection positions of the first air pipe and the second air pipe are located at the top and the bottom side of the conical barrel, respectively. They can be connected by flange interface or buckle type pipe, forming a continuous air flow channel through the layout of double air pipes, maintaining the dynamic balance of gas pressure during the sock suction process.

[0042] Specifically, the mounting bracket is fixed to the side of the hosiery machine and physically connected with the blanking cylinder, so that the movement path of the driving device is in spatial correspondence with the vertical axis of the blanking cylinder. When the material disc is controlled by the driving device to move directly below the blanking cylinder, the top of the conical barrel continuously inhales the socks through the first air pipe, and the bottom maintains air circulation through the second air pipe, avoiding pipe blockage caused by single-point suction. The gradually expanding inner cavity of the conical structure makes the socks slide down the cylinder wall under the action of gravity, reducing the frictional jamming with the pipe wall. The rigid connection characteristics of the mounting bracket can eliminate the vibration deviation generated when the driving device moves, ensuring that the material disc can accurately reach the predetermined station every time.

[0043] Compared with the prior art, the sock suction pipeline of the traditional hosiery machine adopts a straight cylinder structure and is not provided with a mounting bracket, which causes air flow turbulence or pipeline blockage during sock suction, and the driving device and the main body of the hosiery machine lack rigid connection, affecting the positioning accuracy of the material disc. The scheme optimizes the air flow distribution through the conical barrel structure and the double-air-pipe layout, and realizes the continuous and stable operation of the sock suction process by combining the rigid support of the mounting bracket.

[0044] Through the above technical scheme, the present application effectively solves the sock accumulation problem caused by unstable air flow of the existing hosiery machine, improves the air circulation efficiency through the conical structure and double-air-pipe design, and ensures the cooperative movement accuracy of the driving device and the hosiery machine by using the mounting bracket, thereby avoiding sampling deviation caused by mechanical vibration during detection, and improving the accuracy of quality detection.

[0045] The present application further proposes that the bottom surface of the conical barrel structure is connected with a spring 14 to control the opening and closing of a flip cover 13. The flip cover 13 and the bottom surface of the conical barrel structure are in a normally closed state under the control of the spring 14. When the socks are sucked into the flip cover 13 from the first air pipe 1, the gravity of the socks overcomes the spring force of the spring 14 and falls into the collection frame 4 on the side of the hosiery machine 7.

[0046] The spring-controlled flip cover refers to a structure that maintains the closed state of the flip cover through the elastic force of the spring. Specifically, a compression spring or a torsion spring can be used to achieve this. The spring force needs to be adapted to the weight of the socks to ensure that the flip cover only opens when the socks fall. The bottom surface of the conical barrel structure refers to a conical structure that gradually expands at the bottom of the blanking cylinder. Specifically, it can be processed from metal or plastic materials and is used to guide the socks to the direction of the flip cover. The collection frame refers to a container for storing socks. Specifically, it can be an open or box structure with a movable door and is arranged below the blanking cylinder to receive the falling socks.

[0047] Specifically, when the socks are sucked into the dropping cylinder through the first air pipe, they will fall to the flip surface due to gravity. The flip is kept closed by the spring to avoid the undetected socks directly entering the collection frame. When the socks accumulate to a certain weight, the gravity exceeds the spring force, the flip is pressed down to open, and the socks fall into the collection frame. After the falling action is completed, the spring pushes the flip to reset to the closed state, ensuring that the subsequent socks need to accumulate enough weight to trigger the opening. This process automatically controls the batch falling of socks through mechanical structure, avoiding manual intervention.

[0048] Compared with the prior art, the existing hosiery machine usually adopts an open dropping channel or a fixed valve structure, resulting in disordered falling of socks and inability to distinguish between detection samples and regular products. The present scheme realizes batch automatic separation of socks through the linkage design of spring and flip, ensuring the independence and traceability of detection samples, and reducing manual sorting operation.

[0049] Through the above technical scheme, the present application solves the problem of mixed detection samples of socks in the prior art, which leads to difficulty in quality analysis. The precise interception of detection samples is realized through a mechanical weight triggering mechanism, thereby improving the accuracy of quality judgment and reducing the labor intensity of workers.

[0050] The present application further proposes a detection method for socks according to frequency, comprising the following steps

[0051] Step one: after the socks are knitted by the hosiery machine 7 through the hosiery machine control system, the sock transfer arm 8 transfers and cooperates with the toe sewing device 10 to complete the toe sewing of the socks, and then the socks are sucked into the dropping cylinder 3 through the first air pipe 1, and then fall into the collection frame 4;

[0052] Step two: after the hosiery machine 7 produces a set number of socks, the material disc horizontal driving device or the material disc rotating driving device drives the material disc to catch the socks falling from the dropping cylinder 3 as the detected socks, and then the material disc is reset away from the dropping cylinder 3;

[0053] Step three: after step two is completed, step one is repeatedly operated, and the worker judges the quality distribution of the socks in the entire collection frame 4 according to the quality of the detected socks in the material disc, and then adjusts the production parameters of the hosiery machine.

[0054] The setting number of socks refers to the number of socks continuously produced by the hosiery machine, and the detection action is triggered when the preset threshold is reached. Specifically, a photoelectric sensor can be used in combination with a PLC controller to achieve the periodic quality sampling mechanism. The horizontal driving device of the tray refers to an actuator that realizes horizontal linear displacement through the combination of a guide rail and a cylinder. Specifically, a sliding cylinder can be used in combination with a guide rail to achieve precise movement of the tray to the bottom of the feeding cylinder to pick up samples. The rotary driving device of the tray refers to an actuator that realizes arc trajectory motion by rotating the cylinder to drive the swing arm. Specifically, a rotary cylinder with an angle sensor can be used in combination with a stainless steel swing arm to achieve rotation to avoid the feeding channel. The quality distribution refers to establishing a time-defect correlation database by counting the defect types and occurrence time of the detected samples. Specifically, manual recording or image recognition system can be used to trace the production batch of quality problems.

[0055] Specifically, when the hosiery machine continuously produces a preset number of socks, the control system automatically starts the driving device to move the tray directly below the feeding cylinder to pick up the currently produced socks as detection samples. The tray is immediately reset after the sample is obtained, so that the subsequently produced socks can normally fall into the collection frame. The worker only needs to check the samples accumulated in the tray periodically, and by analyzing the concentrated occurrence period of sample defects, the production parameter adjustment node causing quality abnormalities can be located. For example, when three consecutive samples are detected to have the same thread defect, the tension parameter of the thread joining device can be traced back to the corresponding period.

[0056] Compared with the prior art, the prior art relies on manual random sampling and cannot be associated with a specific production period, making it difficult to trace problems. The present method establishes an automatic sampling mechanism triggered by the number, so that the detection samples and production batches form a strict correspondence, and at the same time avoids the sampling omission caused by manual intervention. The rotating or horizontally driven tray mechanism can complete sample separation without interfering with the normal production process, ensuring that the detection data and production timing are synchronized.

[0057] Through the above technical solutions, the present application realizes automatic collection of quality detection samples and precise association with production batches, so that the worker can quickly locate the quality fluctuation period through limited samples. Compared with full number inspection, the detection workload is reduced by more than 90% while ensuring the effectiveness of quality control, and the time distribution characteristics of sample defects can be used to optimize the equipment parameter settings in reverse, forming a closed-loop quality control system.

[0058] The present application further proposes a detection method for detecting socks according to frequency, comprising the following steps:

[0059] Step one, after the hosiery machine knits the socks, the hosiery machine control system completes the sock knitting, and the sock transfer arm transfers the socks to the seam head device to complete the sock seam head, and then the socks are sucked into the material dropping cylinder by the first air pipe, and then fall into the collection frame;

[0060] Step two, after the hosiery machine produces the socks set time, the material disc horizontal driving device or the material disc rotating driving device drives the material disc to catch the socks dropped from the material dropping cylinder as the detected socks, and then the material disc is reset away from the material dropping cylinder;

[0061] Step three, after step two is completed, step one is repeated reciprocally, and the worker judges the quality distribution of the socks in the entire collection frame according to the quality of the detected socks in the material disc, and then adjusts the hosiery machine production parameters.

[0062] Among them, the socks set time refers to performing sampling detection according to a preset time interval, which can be realized by controlling the start period of the driving device by a timer module. The time interval can be set to, for example, 30 minutes or 1 hour according to production needs. The material disc horizontal driving device refers to an actuator that moves the material disc along a straight trajectory, which can be realized by a structure of a cylinder cooperating with a guide rail, so that the material disc can be horizontally moved to the position directly below the material dropping cylinder. The material disc rotating driving device refers to an actuator that transfers the material disc by rotating motion, which can be realized by a structure of a rotating cylinder cooperating with a rotating arm, so that the material disc can enter and exit the material dropping area along an arc trajectory.

[0063] Specifically, when the hosiery machine continuously produces for a preset time, the control system automatically triggers the driving device to move the material disc to the position below the material dropping cylinder. At this time, the negative pressure generated by the air pump sucks the socks with completed seam head into the material dropping cylinder through the first air pipe, and when the selected detection sample falls, the material disc accurately receives the socks. After receiving, the driving device immediately moves the material disc out of the material dropping path, so that the socks produced subsequently can normally fall into the collection frame. The worker can regularly check the samples in the material disc, analyze the quality characteristics of the samples in a specific time period, accurately associate the time node of the quality problem, and then adjust the process parameters of the corresponding period.

[0064] Compared with the prior art, the existing detection method relies on manual random sampling, and cannot establish the corresponding relationship between quality data and production time. The present method establishes the accurate correspondence between the detection sample and the production time period by automatic sampling at regular intervals. In the traditional method, the worker needs to frequently interrupt the production for sampling, while the present scheme realizes non-contact sampling through mechanical automation, ensuring the continuity of production. In addition, the existing technology is difficult to trace the time interval of the quality problem, while the present method can quickly locate the time period of the abnormal process parameters through the time marked sample detection.

[0065] Through the technical scheme, the application realizes the quality monitoring system based on the time dimension, so that the staff can accurately determine the process stability of a specific production period through the detection samples collected at regular time. Since the sampling process is fully automated, the frequency of manual inspection is significantly reduced, and through the sample data related in time, the time node of the process parameter drift can be quickly identified, providing a clear time reference basis for parameter optimization.

[0066] The above merely illustrates the embodiments of the application and is not used to limit the protection scope of the application. For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
