Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a centralized warping yarn breakage automatic stop device. Background Technology

[0002] Warping is a crucial step in the pre-weaving process, its purpose being to wind hundreds to thousands of yarn bobbins onto a warp beam with uniform tension and in a parallel manner, providing high-quality warp yarn for subsequent weaving processes. During warping, yarn breaks can occur due to insufficient yarn strength, poor knots, or friction from equipment parts. If a yarn breakage occurs, the machine must be stopped immediately, and the operator must reconnect the yarn. If breakages are not detected and addressed immediately, it can lead to serious quality problems such as missing warp threads and warp strands on the warp beam, resulting in material waste and reduced production efficiency.

[0003] Currently, the commonly used menopause detection devices in the industry mainly fall into the following two categories: Single yarn detection automatic stop device: Each yarn bobbin is equipped with an individual detection sensor on the bobbin creel. When a yarn breaks, its corresponding sensor immediately sends a signal, controlling the warping machine to stop. The advantages of this solution are rapid detection, accurate positioning, and the ability to directly count the number of yarns in operation (i.e., "head count") by counting the sensor signals. However, its fatal drawback is its high cost. For warping machines with thousands of yarn bobbins, the cost of sensors, wiring, and supporting electrical control systems is very high. At the same time, the large number of electronic components also leads to many points of failure and heavy maintenance work.

[0004] Centralized yarn stop device: A common detection unit is installed in front of each layer of the yarn bobbin reticle, typically consisting of a row of movable light-blocking plates, each corresponding to a single yarn. One end of the device is a light source, and the other end is a light receiver. When the yarn is normal, the tension pulls up the light-blocking plates, allowing the light path to be unobstructed; when the yarn breaks, the light-blocking plates fall down and block the light path, preventing the receiver from detecting the light signal and triggering a stop. This method is simple in structure and significantly cheaper than single-yarn detection. However, its biggest limitation is its single function; it can only determine if a yarn has broken in the current layer, but cannot identify which specific yarn broke, nor can it count the number of yarn heads currently in operation. This no longer meets the requirements of modern textile factories for data-driven production and refined management. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a centralized warping yarn breakage automatic stop device.

[0006] To achieve the above objectives, the technical solution of this utility model is to design a centralized warp breakage self-stop device, including a first crossbar, a left electrical box, and a right electrical box. The first crossbar has a first mounting groove, in which multiple sets of tension ceramic tooth assemblies are installed. The two ends of the first crossbar are respectively installed at the rear ends of the left and right electrical boxes. A second crossbar is installed at the front ends of the left and right electrical boxes, and a second mounting groove is provided on the second crossbar. Multiple sets of yarn guide ceramic parts are installed in the second mounting groove. A third [device / device] for mounting a circuit board is provided on the rear side of each tension ceramic tooth assembly. The mounting slot has multiple magnetic induction elements on the circuit board. The number of tension ceramic tooth assembly, magnetic induction elements, and yarn guide ceramic parts is the same. The circuit board is electrically connected to the alarm unit on the left and / or right electrical boxes. Both the circuit board and the alarm unit are electrically connected to the controller. The tension ceramic tooth assembly includes a housing and a cover plate that mates with the housing. A rotating shaft is provided inside the housing. A tension sensing plate is mounted on the rotating shaft. One end of the tension sensing plate is provided with a yarn guide ceramic tooth, and the other end is provided with a magnet. The end with the magnet is located inside the housing, and the magnet corresponds to the position of the magnetic induction element.

[0007] Optionally, the warning unit is an audible and visual alarm. The audible and visual alarm is used to alert the operator that the equipment has experienced a break in the warp.

[0008] Optionally, the warning unit is a display. The display can be a digital tube display or an electronic display screen, used to display the coordinates of the yarn breakage location or the number of yarn heads.

[0009] Furthermore, a damping buffer block made of elastic material is provided inside the housing to provide cushioning when the tension sensing element rotates. The damping buffer block is located near the trajectory of the magnet's movement within the housing; it is made of elastic material and serves to cushion and limit the magnet or the end of the tension sensing element after it falls. This prevents the tension sensing element from violently impacting the housing due to gravity or elastic force when the yarn suddenly breaks, avoiding magnet detachment, breakage, or impact damage to the magnetic sensing element below, thus improving the device's service life and reliability. Additionally, the buffering prevents the sensing element from rebounding, ensuring the magnet remains stable at the drop position, preventing unstable oscillation signals, and making the state signal detected by the magnetic sensing element more stable and accurate.

[0010] Furthermore, a magnetic shielding spacer is provided between two adjacent magnetic sensing elements on the circuit board. In high-density installations, the magnetic shielding spacer effectively isolates interference from adjacent magnetic fields, ensuring that each magnetic sensing element only detects the state of the magnet directly above it, greatly improving the accuracy of head count and yarn breakage location. The magnetic shielding spacer can be a separate spacer placed inside the housing and cover plate, or the material of the housing or cover plate can be changed to a material with magnetic shielding properties.

[0011] Furthermore, the left and / or right electrical boxes also integrate communication modules. The controller connects to a host computer or cloud platform through these modules to remotely transmit head-bundle data, yarn breakage alarm information, and location information to a monitoring center or mobile terminal. By connecting a single device to the factory's IoT system, managers can monitor the operating status, production efficiency (head-bundle count), and faults (yarn breakage) of multiple warping machines in real time from their offices or via mobile phones or other terminal devices. The accumulated production data (such as the frequency of yarn breakage at each location) can be used to analyze yarn quality and equipment health status, providing a data foundation for predictive maintenance and production process optimization, and greatly improving the level of intelligent equipment management.

[0012] The advantages and beneficial effects of this utility model are as follows: 1. This utility model embeds a non-contact magnetoelectric detection module into a centralized mechanical structure. It replaces thousands of individual yarn sensors with a single low-cost magnetic induction circuit board, achieving yarn count and precise positioning while maintaining significantly lower hardware costs than a single yarn detection system.

[0013] 2. Compared to traditional photoelectric centralized detection, magnetic induction is unaffected by lint and dust accumulation in textile workshops, avoiding false alarms caused by obstructed light paths. The housing design protects the internal magnets and sensing mechanism, further enhancing long-term reliability in harsh industrial environments.

[0014] 3. This utility model is not only a yarn breakage detection tool, but also a data acquisition terminal. It can provide accurate yarn breakage counts in real time, providing crucial data for production management and quality traceability. It can also accurately locate yarn breaks, greatly reducing the processing time for machine operators and improving production efficiency.

[0015] 4. The entire device adopts a modular design, allowing for centralized installation and wiring of circuit boards, tension ceramic tooth components, etc., simplifying on-site installation. The magnetic induction element is integrated onto a single circuit board, making maintenance and replacement very convenient in case of malfunction. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figures 1 to 4 As shown, the centralized warp breakage self-stop device of this utility model consists of a left electrical box 1, a right electrical box 2, a first crossbar 3, and a second crossbar 5. The first crossbar 3 is fixed to the rear end of the left and right electrical boxes 1 and 2 by bolts or screws or other fasteners. The first crossbar 3 has a long strip-shaped first mounting groove 31 for inserting and fixing multiple sets of tension ceramic tooth assemblies 32. The tension ceramic tooth assembly 32 is provided with mounting blocks that match the first mounting groove 31. The second crossbar 5 is installed at the front end of the left and right electrical boxes 1 and 2 by bolts. It has a second mounting groove 51 for installing yarn guide ceramic parts 52. Similarly, the yarn guide ceramic parts 52 are provided with mounting blocks that match the second mounting groove 51.

[0020] The tension ceramic crown assembly 32 comprises a housing 321 and a cover plate 322, which together form a cavity. A rotating shaft 323 is installed within the cavity, and a tension sensing plate 324 is fixed to this shaft and can rotate flexibly around it. One end of the tension sensing plate 324 passes through an opening in the housing 321, where a fabric-covered ceramic crown 325 is mounted; the other end is located within the cavity, with a small magnet 326 embedded at its tip. On the inner wall of the housing 321, directly opposite the endpoint of the magnet 326's drop trajectory or the rotational displacement position of the tension sensing plate 324, a damping buffer block (not shown in the figure) made of silicone is provided to absorb the impact of the drop, protect the magnet 326, and prevent rebound. In order to prevent the magnetic fields of adjacent magnets 326 from interfering with each other under high-density installation, a magnetic shielding spacer (not shown in the figure) is provided between two adjacent magnets 326. The magnetic shielding spacer can be a separate spacer placed inside the housing 321 and the cover plate 322, or the material of the housing 321 or the cover plate 322 can be changed to a material with magnetic shielding effect.

[0021] On the rear side of the tension ceramic crown assembly 32, there is an inwardly recessed third mounting groove 42. One or more circuit boards 4 are laid and fixed in this groove. Multiple magnetic induction elements 41 are soldered onto the circuit boards 4 at the same spacing as the tension ceramic crown assembly 32.

[0022] The left electrical box 1 houses a controller (such as an STM32 series microcontroller) and a communication module (such as a 4G or Wi-Fi module). The controller can also be placed in a separate location. The right electrical box 2 has an alarm unit 6 integrated with a buzzer, LED lights, and a digital display screen mounted on its panel. Both the circuit board 4 and the alarm unit 6 are connected to the controller via cables.

[0023] Work process: Yarn loading and initialization: The operator guides the yarn through the guide ceramic piece 52 and the yarn-passing ceramic tooth 325 in sequence. The tension of all the yarns pulls each tension sensor 324 to the working position (the magnet 326 corresponds to the position of the magnetic sensing element 41). When the equipment starts, the controller performs head count, scans all magnetic sensing elements 41, counts the number of heads in the working position, which is the total head count, and displays it on the screen of the alarm unit 6.

[0024] Operation monitoring: The warping machine is operating normally. The controller continuously monitors the status of all magnetic induction elements 41.

[0025] Broken yarn handling: Assuming yarn number 15 breaks, the corresponding tension sensing plate 324 loses tension and rotates around the rotation axis 323 under its own gravity, causing it to either fall (the end of tension sensing plate 324 with the passing porcelain tooth 325 is heavier) or rise (the end of tension sensing plate 324 with the magnet 326 is heavier). At this time, the magnet 326 moves away from the magnetic sensing element 41, and the output signal of the element changes. After receiving this signal, the controller immediately performs the following actions: (a) sends a stop command to the warping machine main control; (b) triggers the audible and visual alarm to sound and flash; (c) highlights "Broken yarn location: Layer X, Column 15" on the display screen.

[0026] Data Upload: Simultaneously, the controller transmits yarn breakage events, time and location information, as well as real-time head count data, to the host computer server or cloud platform via the communication module through the factory LAN or mobile network for the production management system to record and analyze.

[0027] The bolts, nuts, screws, welding, etc. used to connect two or more parts in the above-mentioned fixing and installation are all known to those skilled in the art and will not be repeated here. The housing, cover plate, cross shaft and other components described in this article are adjusted according to the mutual relationship between the components, with the main purpose of preventing interference between different components.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
