Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of screen cylinder detection, and particularly relates to a spinning ring screen cylinder automatic detection system. BACKGROUND

[0002] In the spinning production process, the spinning ring screen cylinder is a key component, and its quality directly affects the spinning quality and the production stability. The traditional detection method mainly relies on manual detection, however, manual detection has many disadvantages.

[0003] On the one hand, manual detection is low in efficiency. Spinning production is usually continuous mass production, and a large number of screen cylinders need to be detected. Manual detection of the appearance, air pressure and other aspects of the screen cylinder one by one not only consumes a lot of time, but also is difficult to meet the high rhythm demand of production, which may cause delay of the production process and reduce the overall production efficiency. On the other hand, manual detection is prone to errors. Due to visual fatigue, subjective judgment difference and other factors, the detection results of the same screen cylinder by different detection personnel may be different. Even the same detection personnel may make inconsistent judgments at different times. Such errors may cause some screen cylinders with quality problems to be misjudged as qualified products and put into use, thereby affecting the spinning quality and increasing the product defect rate. Some qualified products may also be misjudged as unqualified products, causing unnecessary waste and increasing production costs.

[0004] In addition, manual detection is labor-intensive, and long-time and high-intensity detection work is easy to cause fatigue of the detection personnel, which not only affects the detection efficiency, but also may cause harm to the health of the detection personnel.

DETAILED DESCRIPTION

[0032] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0033] Embodiment: As shown in the figure, the embodiment of the present application provides a spinning ring blowing screen cylinder automatic detection system, which comprises a screen cylinder conveying belt, a screen cylinder appearance detection module, a screen cylinder wind pressure detection module and an industrial computer. Figure 1

[0034] Among them, the screen cylinder conveying belt is used to convey the screen cylinder after cleaning and drying, and the screen cylinder after cleaning and drying is placed on the screen cylinder conveying belt. The screen cylinder conveying belt sends the screen cylinder into the detection area at a stable speed. The detection area includes a screen cylinder appearance detection module detection area and a screen cylinder wind pressure detection module detection area. An appearance unqualified outlet is arranged on the screen cylinder conveying belt at the screen cylinder appearance detection module. A wind pressure unqualified outlet is arranged on the screen cylinder conveying belt at the screen cylinder wind pressure detection module. ​

[0035] The wire mesh tube appearance inspection module is located near the feed end of the wire mesh tube conveyor belt. The wire mesh tube appearance inspection module is used to inspect the appearance of the wire mesh tube.

[0036] The wire mesh cylinder air pressure detection module is located near the discharge end of the wire mesh cylinder conveyor belt. The wire mesh cylinder air pressure detection module is used to detect the air flow rate passing through the wire mesh cylinder within a certain period of time, and to determine whether the wire mesh cylinder is qualified based on the set measurement value standard.

[0037] The wire mesh conveyor belt, the wire mesh appearance inspection module, and the wire mesh air pressure detection module are electrically connected to an industrial computer. The industrial computer controls the start and stop of the wire mesh conveyor belt and displays the inspection results from the wire mesh appearance inspection module and the wire mesh air pressure detection module. The industrial computer has a human-machine interface, which is an important platform for communication and interaction between the operator and the industrial computer's automatic inspection system. It has the following functions:

[0038] The system displays inspection information and real-time inspection status of the wire mesh cylinders, including appearance inspection results, wind pressure inspection results, reasons for non-compliance, etc. Operators can intuitively understand the inspection status of each wire mesh cylinder through the interface.

[0039] The parameter settings allow operators to set and adjust the parameters of the detection system according to actual production needs, such as wire mesh cylinder detection specifications, air pressure setpoints, and measurement standard values.

[0040] Fault alarm: When the detection system malfunctions or encounters abnormal conditions, the human-machine interface will promptly issue an alarm signal and display fault information, facilitating timely troubleshooting and repair by operators and ensuring the normal operation of the detection system.

[0041] The industrial computer plays a crucial role in the core control and data processing of the entire automatic inspection system for spinning ring blown wire mesh cylinders. It is electrically connected to the wire mesh cylinder conveyor belt, the wire mesh cylinder appearance inspection module, and the wire mesh cylinder air pressure inspection module, enabling information exchange and control command transmission. In terms of control, the industrial computer can precisely control the start and stop of the wire mesh cylinder conveyor belt according to preset programs and inspection procedures, ensuring that the wire mesh cylinders arrive at each inspection module in the prescribed order and time. Simultaneously, it can perform real-time monitoring and parameter adjustment of the wire mesh cylinder appearance inspection module and the wire mesh cylinder air pressure inspection module, ensuring the stability and accuracy of the inspection process. In terms of data processing, the industrial computer receives a large amount of inspection data from the two inspection modules and uses advanced algorithms and preset specifications to perform in-depth analysis and processing of this data, quickly and accurately determining whether the appearance and air pressure of each wire mesh cylinder are qualified. Furthermore, the industrial computer has powerful data display capabilities, displaying the inspection results in intuitive charts and data on the screen, allowing operators to understand the inspection status in real time, promptly identify anomalies, and take corresponding measures. Through the intelligent management of the industrial computer, the entire inspection system can achieve efficient and automated operation, greatly improving inspection efficiency and accuracy.

[0042] In this embodiment, the screen tube appearance inspection module includes a multi-view industrial camera and an illumination system. The multi-view industrial camera is used to cover the circumference of the screen tube for multi-directional shooting. The ring backlight of the illumination system is used to highlight the outline of the screen tube, and the side lighting of the illumination system is used to detect impurities and deformations on the surface of the screen tube. Through the collaborative work of multiple cameras, all-round image information of the screen tube can be obtained, avoiding blind spots in detection. For example, multiple cameras are arranged in a ring around the screen tube, with each camera responsible for shooting a part of the screen tube. These images are then stitched and processed to obtain a complete image of the screen tube's appearance. The illumination system provides good shooting conditions for the industrial camera. It includes two parts: ring backlight and side lighting. The ring backlight can highlight the outline of the screen tube, making the screen tube contrast sharply with the background, which makes it easier for the camera to clearly capture its edge information. The side lighting is mainly used to detect impurities and deformations on the surface of the screen tube. With the illumination of the side light, surface impurities will produce different reflective effects, and deformed parts will also show changes in light and shadow, which can be accurately identified by the industrial camera.

[0043] In this embodiment, the appearance inspection of the wire mesh cylinder inspection module includes wire mesh damage detection, wire mesh deformation detection, mesh uniformity detection, and surface cleanliness detection, wherein:

[0044] Mesh clogging detection: Mesh clogging can seriously affect the uniformity of airflow during spinning, thus affecting the spinning quality. By using specific image processing algorithms to analyze the captured images of the wire mesh cylinder, the presence of mesh clogging can be identified.

[0045] Screen breakage detection, a broken screen cylinder cannot function properly in filtering and airflow regulation, which may cause quality problems such as broken filaments during spinning. Image comparison technology is used to compare the detected image with the standard image to detect whether the screen is broken.

[0046] Screen deformation detection, screen deformation will change its original structural parameters and affect the spinning ring blowing effect. The profile shape of the screen in the image is analyzed to determine whether deformation has occurred.

[0047] Mesh uniformity detection, mesh uniformity is crucial to the uniformity of spinning. Image analysis method is used to measure the size and distribution of mesh to evaluate the uniformity of mesh.

[0048] Surface cleanliness detection, impurities on the surface of the screen cylinder may contaminate the spinning raw materials and affect product quality. Side light assisted detection is used to identify impurities and stains on the surface of the screen cylinder.

[0049] In this embodiment, the appearance detection data of the screen cylinder appearance detection module is analyzed by the industrial computer and the screen cylinder appearance detection specification parameters set therein. The standard value is compared to determine whether the screen cylinder appearance is qualified. The screen cylinder appearance detection module also includes a cylinder pusher. If the screen cylinder appearance is qualified, it will continue to be conveyed through the screen cylinder conveying belt. If the screen cylinder appearance is unqualified, the industrial computer records the defect information and pushes it to the appearance unqualified outlet through the cylinder pusher. At the same time, the unqualified reason is displayed on the human-computer interaction interface. The appearance detection data obtained by the screen cylinder appearance detection module will be transmitted to the industrial computer for processing. The screen cylinder appearance detection specification parameters are pre-set in the industrial computer. The actual detection data is compared with these set parameters for detailed analysis, for example, for screen breakage detection, the maximum allowed broken area is set. If the actual detected broken area exceeds the set value, it is determined as unqualified. For mesh uniformity detection, the tolerance range of mesh size is set. If the mesh size exceeds this range, it is considered unqualified. The industrial computer accurately determines whether the screen cylinder appearance is qualified according to the comparison result. If the appearance is qualified, the screen cylinder will continue to be conveyed through the conveying belt to the next detection link. If the appearance is unqualified, the industrial computer will not only record detailed defect information including defect type, position, etc., but also control the cylinder pusher to push the unqualified screen cylinder to the appearance unqualified outlet for subsequent processing.

[0050] As Figures 2-7As shown, in the present embodiment, the screen cylinder wind pressure detection module includes an automatic wind pressure inspection arm and a wind pressure detection device, the wind pressure detection device includes a wind pressure detector 3, a detector cover 4, a wind pressure detector cylinder 5 for opening and closing the detector cover 4, an air inlet pipe 9 for supplying air to the wind pressure detector 3, an electromagnetic valve 10 arranged on the air inlet pipe 9, and an air pressure sensor 11 for controlling the air inlet amount of the electromagnetic valve 10. The automatic wind pressure inspection arm is used to hold the screen cylinder 6 and place it into the wind pressure detection device. The screen cylinder 6 that passes the appearance detection is conveyed to the detection area of the screen cylinder wind pressure detection module by the screen cylinder conveying belt. The automatic wind pressure inspection arm holds the screen cylinder 6 and places it into the wind pressure detector 3 of the wind pressure detection device. When the arm holds the screen cylinder 6, a command is sent to the wind pressure detector cylinder 5 to control the opening of the detector cover 4. After the detector cover 4 is opened, the automatic wind pressure inspection arm holds the screen cylinder 6 and places it into the wind pressure detector 3. The wind pressure detector cylinder 5 closes the detector cover 4, and the electromagnetic valve 10 on the air inlet pipe 9 receives the air inlet command to supply air to the wind pressure detector through the air inlet pipe 9. The air inlet amount of the electromagnetic valve 10 is controlled by the air pressure sensor 11 in the wind pressure detector 3 to keep the wind pressure in the wind pressure detector 3 at a set value of 30 Pa. The set value is used to detect whether the screen cylinder 6 is qualified. Within a certain time, the wind pressure performance of the screen cylinder 6 is evaluated by measuring the air flow through the screen cylinder 6. The size of the air flow reflects the degree of obstruction of the screen cylinder 6 to the air flow, thereby determining whether it meets the production requirements.

[0051] In the present embodiment, the wind pressure detection data obtained by the screen cylinder wind pressure detection module is also transmitted to the industrial computer for analysis and processing. The wind pressure detection data of the screen cylinder wind pressure detection module is analyzed by comparing with the set value of the wind pressure detection specification parameters of the screen cylinder 6 set in the industrial computer, to determine whether the wind pressure of the screen cylinder 6 is qualified. The wind pressure detection set value of the industrial computer is 60.5 m 3 / h±1 m 3 / h. If the actual detected air flow is within the set value range, it is determined that the wind pressure detection of the screen cylinder 6 is qualified. The detector cover 4 is opened by the wind pressure detector cylinder 5, and the automatic wind pressure inspection arm holds the screen cylinder 6 that passes the wind pressure detection in the wind pressure detector 3 and places it on the screen cylinder conveying belt for continuous conveying to the screen cylinder 6 installation area. If the actual detected air flow is not within the set value range, it is determined that the wind pressure detection of the screen cylinder 6 is unqualified. The automatic wind pressure inspection arm holds the screen cylinder 6 that fails the wind pressure detection in the wind pressure detector 3 and places it in the wind pressure unqualified outlet for conveying to the cleaning area for re-cleaning, so as to be detected again to ensure that all screen cylinders 6 in use meet the wind pressure performance requirements.
