Description

Technical Field

[0001] This application relates to the field of yarn conveying technology, and in particular to a fiber bundle conveying end-breakage automatic stop device. Background Technology

[0002] In industrial production, glass fiber bundles are widely used in various product manufacturing fields. With the continuous development of related industries, the requirements for automation and efficiency in glass fiber bundle processing are also increasing. Stable transport of glass fiber bundles is crucial for ensuring the processing quality and production efficiency of products such as short fiber mats. The stability of the transport process directly affects the performance of the final product and production benefits. Therefore, precise control of the fiber bundle transport process has become a key focus in the industry.

[0003] The related technology discloses a loom warp breakage stopping device, including warp yarns, warp stop strips, warp stop plates, and photoelectric sensors. Multiple warp yarns pass through their corresponding warp stop plates and are lifted up. There are multiple warp stop strips, each passing through a corresponding warp stop plate. There are multiple photoelectric sensors located at the lower end of each warp stop strip. Under normal circumstances, the photoelectric sensors can receive light signals. When a warp yarn breaks, the warp stop plate falls under the action of gravity and abuts against the upper end of the warp stop strip, while the lower end blocks the light signal, so that the photoelectric sensors cannot receive the signal, thereby determining which warp yarn on which warp stop strip has a problem.

[0004] Although optical sensors have high sensitivity, they are also sensitive to factors such as ambient light and dust. They are less reliable in complex production environments and cannot accurately and reliably detect the breakage of fiber bundles. Consequently, they cannot effectively control the stopping of fiber bundle delivery and cannot meet the needs of modern production. Utility Model Content

[0005] This application provides a fiber bundle delivery end-stop device to solve the problem of poor reliability of current optical sensors in monitoring fiber bundle end-stop conditions in complex environments.

[0006] A fiber bundle conveying end-break self-stop device includes: The support body includes a bracket and a support assembly. Two brackets are vertically arranged and spaced apart along the length direction. Two support assemblies are provided and located on the same side of the corresponding bracket along the width direction. Glass fiber bundles are transmitted on the support body for processing. The self-stopping component includes a partition, a controller, and a conductor. The partition extends along its length and is located at both ends of the support component. The partition includes a positive electrode layer, a negative electrode layer, and an insulating layer. The positive electrode layer and the negative electrode layer are electrically connected to the controller and are isolated by the insulating layer. Multiple conductors are provided along the length and are all fitted with the partitions. Multiple glass fiber bundles pass through their corresponding conductors, causing the conductors to rise. When the glass fiber bundles break, the corresponding conductors fall and abut against the partitions, thereby connecting the positive electrode layer and the negative electrode layer, and thus the controller stops the transmission.

[0007] By adopting the above technical solution, the positive and negative electrode layers of the isolation component are separated by an insulating layer and are not conductive under normal circumstances. The conductive component is sleeved on the isolation component and, when supported by the fiber bundle, does not contact the positive and negative electrode layers. When the fiber bundle breaks, the conductive component falls and comes into contact with the isolation component, connecting the positive and negative electrode layers to form a closed circuit loop. The controller immediately stops transmission upon receiving the signal. This mechanism achieves automated control with "stop upon breakage," offering high precision and avoiding the need for frequent manual checks due to accidental triggering of optical sensors caused by environmental factors.

[0008] In one embodiment, the positive electrode layer and the insulating layer have U-shaped cross-sections with their openings facing upwards. The insulating layer covers the negative electrode layer, and the positive electrode layer covers the insulating layer. The conductive element includes a perforated ring and a stop-wave plate. A glass fiber bundle passes through the perforated ring. The stop-wave plate is located at the lower end of the perforated ring and has a through hole. The partition element has multiple through holes. The upper end of the partition element is adapted to the shape of the upper end of the through hole. The stop-wave plate has a conductive portion at the upper end of the through hole, and the conductive portion can conduct electricity between the positive electrode layer and the negative electrode layer.

[0009] By adopting the above technical solution, the positive electrode layer and the insulating layer have U-shaped openings facing upwards. The insulating layer is fitted over the negative electrode layer, and the positive electrode layer is fitted over the insulating layer, forming a layered isolation structure. This design ensures electrical isolation between the positive and negative electrode layers under normal conditions, while providing a precise contact interface for conduction when the conductive component falls. The upper end of the partition is shaped to match the upper end of the through hole, allowing the conductive part to perfectly conduct between the positive and negative electrode layers when it falls, improving the stability of the self-stop mechanism.

[0010] In one embodiment, the perforated ring is made of ceramic or fiberglass.

[0011] By adopting the above technical solutions, ceramic materials can reduce frictional losses during fiber bundle transmission, prevent fiber bundle fuzzing, and extend the service life of perforated rings; fiberglass materials are lightweight and high-strength, which can ensure structural stability and avoid electrostatic interference or accidental conductivity that may be caused by metal materials.

[0012] In one embodiment, the support assembly includes a first support plate and a second support plate, the first support plate and the second support plate being disposed on the same side of the corresponding bracket along the width direction, the first support plate being disposed on the upper side of the second support plate, the support body also including guide rods, the guide rods being provided in two, the two ends of the guide rods being fixed to the two first support plates along the length direction, the two guide rods being spaced apart along the width direction, the two ends of the partition being fixed to the two second support plates and located between the two guide rods, the glass fiber bundle abutting the upper end of the guide rod and passing through the perforated ring to lift the conductive member.

[0013] By adopting the above technical solution, the glass fiber bundle abuts against the upper ends of the two guide rods and is taut for transmission, which enables the conductor to be lifted between the two guide rods, making it easy for the conductor to fall and automatically stop after the glass fiber bundle breaks.

[0014] In one embodiment, the support body further includes an abutment plate, which is disposed at one end of the support assembly away from the bracket. The abutment plate extends along the length direction and is disposed at both ends between the first support plate and the second support plate. The abutment plate is provided with a plurality of limiting holes along the length direction, and a plurality of glass fiber bundles pass through the corresponding limiting holes and then abut against the guide rod.

[0015] By adopting the above technical solution, the fiber bundles first pass through the limiting holes on the abutment plate and then abut against the guide rod. The limiting holes can position multiple fiber bundles one by one, so that each fiber bundle maintains a fixed distance when passing through the guide rod and the perforated ring, avoiding mutual entanglement or misalignment, and further improving the stability of the transmission process and the accuracy of monitoring.

[0016] In one embodiment, the positive electrode layer, the insulating layer, and the negative electrode layer are arranged sequentially along the width direction.

[0017] By adopting the above technical solution, another embodiment of the isolation component is provided. The positive electrode layer, the insulating layer and the negative electrode layer are arranged sequentially along the width direction to form a layered structure, which makes the circuit path clear and reduces electromagnetic interference between layers. At the same time, the layered layout makes it easy for the conductive component (stop plate) to contact the positive and negative electrode layers simultaneously when it falls, ensuring the reliability of circuit conduction and avoiding poor contact caused by misalignment between layers.

[0018] In one embodiment, the partition member is provided with a plurality of abutting members, the abutting members are provided at the upper end of the partition member and extend along the width direction, the plurality of abutting members are spaced apart along the length direction, and each of the conductive members is provided with abutting members on both sides along the length direction.

[0019] By adopting the above technical solution, the abutment members (extending along the width direction) at the upper end of the partition are set on both sides of the conductive member, ensuring that the stop plate falls vertically and accurately contacts the positive and negative electrode layers. Simultaneously, the abutment members are spaced apart along the length direction, allowing for zoned positioning of multiple conductive members, preventing mutual interference when adjacent conductive members fall, and improving the independence of multi-channel monitoring. The fixed connection between the abutment members and the partition enhances the overall rigidity of the partition, preventing deformation caused by long-term stress, ensuring the relative position stability of the positive and negative electrode layers, and maintaining the reliability of circuit conduction.

[0020] In one embodiment, the abutting member is an abutting block, the abutting block is provided with a first locking portion, the insulating layer is provided with a second locking portion, and the first locking portion and the second locking portion are locked and fixed.

[0021] By adopting the above technical solution, the first locking part of the abutment block and the second locking part of the insulating layer are locked together, and the abutment can be installed and disassembled without additional tools, which is convenient for equipment maintenance and repair; the locking structure can ensure that the abutment will not loosen during use and maintain the limiting function of the conductive part.

[0022] In one embodiment, the stop-warp piece is I-shaped and the upper end is made of conductive material. The insulating layer has a plurality of fixing holes along the height direction, and the plurality of fixing holes are spaced apart along the length direction. The stop-warp piece is passed through the corresponding fixing holes.

[0023] By adopting the above technical solution, the fixing holes of the insulation layer cooperate with the stop-warp piece to limit the shaking of the stop-warp piece under normal conditions, ensuring that it can fall vertically when the fiber bundle breaks, thereby further improving the sensitivity and accuracy of monitoring.

[0024] In one embodiment, the positive electrode layer is provided in multiple ways along the length direction and corresponds one-to-one with the stop-wave plate. Each positive electrode layer is fixed to the insulating layer and can be connected to the negative electrode layer. The controller is electrically connected to the multiple positive electrode layers respectively.

[0025] By adopting the above technical solution, the controller sequentially energizes multiple positive electrode layers and determines which channel is energized while the negative electrode layer is conducting, thus pinpointing the location of the corresponding stop-loss sheet and achieving "precise positioning of single fiber bundle breakage." This design eliminates the need for manual inspection, improving fault diagnosis efficiency, facilitating rapid repair, and reducing downtime.

[0026] In summary, this application includes at least one beneficial effect: 1. The positive and negative electrode layers of the isolation component are separated by an insulating layer and are not conductive under normal circumstances. The conductive component is sleeved on the isolation component and, when supported by the fiber bundle, does not contact the positive and negative electrode layers. When the fiber bundle breaks, the conductive component falls and comes into contact with the isolation component, connecting the positive and negative electrode layers and forming a closed circuit loop. The controller immediately stops transmission upon receiving the signal. This mechanism achieves automated control with "stop upon breakage," offering high precision and avoiding frequent detection by personnel due to frequent triggering of optical sensors caused by environmental factors.

[0027] 2. Another embodiment of the isolation component is provided, in which the positive electrode layer, the insulating layer and the negative electrode layer are arranged sequentially along the width direction to form a layered structure, making the circuit path clear and reducing electromagnetic interference between layers; at the same time, the layered layout makes it easy for the conductive component (stop plate) to contact the positive and negative electrode layers simultaneously when it falls, ensuring the reliability of circuit conduction and avoiding poor contact caused by misalignment between layers.

[0028] 3. The abutment members (extending along the width direction) at the upper end of the partition are located on both sides of the conductive element, ensuring that the stop plate falls vertically and accurately contacts the positive and negative electrode layers. Simultaneously, the abutment members are spaced apart along the length direction, allowing for zoned limiting of multiple conductive elements, preventing mutual interference when adjacent conductive elements fall, and improving the independence of multi-channel monitoring. The fixed connection between the abutment members and the partition enhances the overall rigidity of the partition, preventing deformation due to long-term stress, ensuring the relative stability of the positive and negative electrode layers, and maintaining the reliability of circuit conduction.

[0031] The following is in conjunction with the appendix Figure 1-7 The fiber bundle conveying end-break automatic stop device provided in this application will be described in further detail.

[0032] Example 1 Please see Figure 1-7 The fiber bundle conveying end-stop device provided in this application embodiment includes a support body 1 and an end-stop component 2.

[0033] The support body 1 is used to support the glass fiber bundle for transmission to facilitate subsequent processing, and the self-stop component 2 is used to detect fiber bundle breakage and control the conveying to stop, avoiding production losses, and achieving the effect of accurately detecting fiber bundle breakage and timely controlling the conveying to stop.

[0034] like Figure 1 As shown, the support body 1 includes a bracket 11 and a support assembly 12. Two brackets 11 are vertically arranged and spaced apart along the length direction. The brackets 11 can be made of metal, such as stainless steel or aluminum alloy, to ensure sufficient strength and stability; alternatively, high-strength plastics or other materials can be used. The brackets 11 provide overall support, offering a stable foundation for the entire device. Two support assemblies 12 are located on the same side of their corresponding brackets 11 along the width direction. Glass fiber bundles are transmitted on the support body 1 for subsequent processing.

[0035] Specifically, the support assembly 12 includes a first support plate 121 and a second support plate 122. The first support plate 121 and the second support plate 122 are located on the same side of the corresponding bracket 11 along the width direction, with the first support plate 121 positioned above the second support plate 122. The first support plate 121 and the second support plate 122 can be rectangular plate structures. The first support plate 121 and the second support plate 122 can be fixed to the bracket 11 by welding, bolting, or other methods, and they are used to install other components. The support body 1 also includes guide rods 13. Two guide rods 13 are provided, and their ends along the length direction are fixed to the two first support plates 121. The two guide rods 13 are spaced apart along the width direction. The guide rods 13 are generally smooth, round metal rods, such as chrome-plated iron rods, or ceramic rods can also be used. This reduces the friction between the guide rods and the glass fiber bundles, preventing damage to the fiber bundles. The glass fiber bundles abut against the upper end of the guide rods 13, guiding the direction of fiber bundle transmission. In addition, the support body 1 also includes an abutment plate 14, which is located on the side of the support assembly 12 away from the bracket 11. The abutment plate 14 extends along the length direction and its two ends are located between the first support plate 121 and the second support plate 122 along the height direction. The abutment plate 14 has multiple limiting holes 141 along its length direction. Multiple glass fiber bundles pass through their corresponding limiting holes 141 and then abut against the upper end of the guide rod 13. The limiting holes 141 can be circular or square, etc., and are made of ceramic material. Their function is to position and guide the glass fiber bundles, while preventing frictional static electricity from being generated with the fiber bundles, thus ensuring the stability of fiber bundle transmission. The combination of the bracket 11, the support assembly 12, the guide rod 13, and the abutment plate 14 forms a stable fiber bundle transmission support structure, which can effectively guide the glass fiber bundles for transmission.

[0036] like Figure 2 As shown, the self-stopping component 2 includes a partition 21, a controller, and a conductor 22. The partition 21 extends along the length direction and is respectively located at both ends on the support component 12. The partition 21 includes a positive electrode layer 211, a negative electrode layer 212, and an insulating layer 213. Both the positive electrode layer 211 and the negative electrode layer 212 are electrically connected to the controller and are isolated by the insulating layer 213. Multiple conductors 22 are provided along the length direction and are all fitted with partitions 21. Multiple glass fiber bundles pass through their corresponding conductors 22, causing the conductors 22 to rise. When the glass fiber bundles break, the conductors 22 fall and abut against the partitions 21, thereby connecting the positive electrode layer 211 and the negative electrode layer 212, thus making the circuit conductive. The controller then controls the subsequent processing device to stop, and the glass fiber bundles stop being transported.

[0037] Specifically, the two ends of the partition 21 are fixed to the two second support plates 122 and are located between the two guide rods 13 along the width direction. The conductive member 22 includes a perforated ring 221 and a stop-warp piece 222. The glass fiber bundle abuts against the upper end of the first guide rod 13 along the width direction, then passes through the perforated ring 221, and then abuts against the upper end of the second guide rod 13 before being conveyed to the processing device for processing. The perforated ring 221 is made of ceramic or fiberglass, which can reduce friction and thus prevent the fiber bundle from becoming fuzzy due to static electricity. The stop-warp piece 222 is located at the lower end of the perforated ring 221 and has a through hole 2221. The partition 21 has multiple through holes 2221 of the stop-warp pieces 222. The upper end of the partition 21 is shaped to match the upper end of the through hole 2221. The stop-warp piece 222 is provided with a conductive part 2222 at the upper end of the through hole 2221. The conductive part 2222 can conduct the positive electrode layer 211 and the negative electrode layer 212. The conductive part 2222 is made of conductive material, while the other parts of the stop-wave piece 222 are made of insulating material.

[0038] When the glass fiber bundle is in normal transmission mode, it is taut due to the contact between the two guide rods 13. The perforated ring 221 lifts the conductive element 22, at which point the positive electrode layer 211 and the negative electrode layer 212 are disconnected. When the glass fiber bundle breaks, the conductive element 22 loses its support and descends. The conductive part 2222 at the upper end of the stop plate 222 contacts the upper end of the partition 21, connecting the positive electrode layer 211 and the negative electrode layer 212, thus making the circuit conductive. After receiving the signal, the controller stops the transmission.

[0039] In this embodiment, the upper end of the partition 21 is flush, the through hole 2221 is square and also flush at the upper end, the positive electrode layer 211 and the insulating layer 213 have U-shaped cross-sections with their openings facing upwards, the negative electrode layer 212 has a square cross-section, the insulating layer 213 covers the negative electrode layer 212, and the positive electrode layer 211 covers the insulating layer 213. This structural design effectively isolates the positive electrode layer 211 and the negative electrode layer 212, preventing the circuit from conducting under normal conditions. The controller supplies a +12V weak current to the positive electrode layer 211 while simultaneously connecting the negative electrode layer 212. In other embodiments, the positions of the positive electrode layer 211 and the negative electrode layer 212 can be changed. The positive electrode layer 211 and the negative electrode layer 212 can be made of metal materials with good conductivity, such as copper or aluminum, while the insulating layer 213 is made of materials with excellent insulation properties, such as rubber or plastic.

[0040] The implementation principle of this embodiment is as follows: The fiber bundle conveying breakage self-stop device provides stable transmission support for the glass fiber bundle through the support body 1, ensuring the smooth transmission of the fiber bundle. The self-stop component 2 uses the changes in the fiber bundle state to control the circuit on and off. When the fiber bundle breaks, it can accurately detect and control the conveying to stop in time. Compared with traditional detection and processing methods, it overcomes the problems of labor-intensive manual inspection, poor real-time performance, unstable accuracy of traditional mechanical sensors, and poor reliability of optical sensors. It greatly improves production efficiency and product quality, and has made significant improvements and contributions to existing technologies.

[0041] Example 2 like Figures 3 to 5 As shown, the difference between this embodiment and the above embodiment is that: the partition member 21 is provided with a plurality of abutment members 23, the abutment members 23 are provided at the upper end of the partition member 21 and extend along the width direction, the plurality of abutment members 23 are spaced apart along the length direction, and each conductor member 22 is provided with abutment members 23 on both sides along the length direction. Specifically, the abutment members 23 can be fixed to the upper end of the partition member 21 by means of bonding, welding or snapping, etc. The abutment members 23 are made of insulating material and can be abutment blocks. The abutment blocks are provided with a first locking part and can be fixed to the partition member 21.

[0042] In addition, the structure of the partition 21 can also be changed. The positive electrode layer 211, the insulating layer 213, and the negative electrode layer 212 are arranged sequentially along the width direction, and the cross-section of each is square. The partition 21 passes through the through hole 2221 of the conductor 22, allowing the conductive part 2222 to fall down, thereby making the positive electrode layer 211 and the negative electrode layer 212 on both sides conductive. The conductor 22 is provided with abutting members 23 on both sides. In this embodiment, the insulating layer 213 of the partition 21 can be provided with a second locking part 2131. The first locking part 231 and the second locking part 2131 are locked together and fixed. The first locking part 231 can be a locking block, and the second locking part 2131 can be a locking groove. The abutting member 23 abuts against the conductor 22 to prevent the conductor 22 from tilting when it falls down, which could easily affect the fiber bundles on both sides and the conductor 22.

[0043] The implementation principle of this embodiment is as follows: By setting the abutment member 23, this embodiment further improves the stability and reliability of the device and prevents the adverse effects caused by the tilting of the conductor 22.

[0044] Example 3 like Figure 6As shown, the difference between this embodiment and the above embodiment is that when the positive electrode layer 211, the negative electrode layer 212 and the insulating layer 213 are arranged sequentially along the width direction, the stop-warp piece 222 can also be in the shape of an I-beam and the upper end is made of conductive material. At this time, the upper and lower ends of the stop-warp piece 222 can be detachably connected. The insulating layer 213 is provided with multiple fixing holes along the height direction. The multiple fixing holes are spaced apart along the length direction. The stop-warp piece 222 is provided with corresponding fixing holes. This not only prevents the stop-warp piece 222 from affecting the conductive parts 22 and fiber bundles on both sides in the length direction when it falls, but also allows the positive electrode layer 211 and the negative electrode layer 212 to be connected in the shape of an I-beam.

[0045] The implementation principle of this embodiment is as follows: This embodiment optimizes the structure of the stop warp piece 222. The cooperation between the I-shaped stop warp piece 222 and the fixing hole can not only ensure normal conduction function, but also avoid interference with surrounding components. On the basis of accurately detecting fiber bundle breakage and timely controlling the stop of conveying, the applicability and durability of the device in actual production are enhanced, and the stability and reliability of the device are further improved.

[0046] Example 4 like Figure 7 As shown, the difference between this embodiment and the above embodiment is that: multiple positive electrode layers 211 are provided along the length direction and correspond one-to-one with the stop-the-warp pieces 222. The spacing between the multiple positive electrode layers 211 ensures that they do not interfere with each other. Each positive electrode layer 211 is fixed to the insulating layer 213 and can conduct with the negative electrode layer 212. The controller is electrically connected to the multiple positive electrode layers 211 respectively. Specifically, the cross-section of the positive electrode layer 211 can be square or U-shaped. The controller sequentially energizes each positive electrode layer 211 within a certain period of time, and then determines which positive electrode layer 211 is energized and the negative electrode layer 212 conducts, thus forming a closed circuit. This allows the controller to determine which stop-the-warp piece 222 corresponding to that positive electrode layer 211 has fallen. In another scenario, multiple negative electrode layers 212 can be provided, each corresponding to a stop-loss piece 222. All multiple negative electrode layers 212 are electrically connected to the controller. Through multiple stop-loss pieces 222, each negative electrode layer 212 can be connected to the positive electrode layer 211, thereby determining which stop-loss piece 222 corresponding to which negative electrode layer 212 has fallen.

[0047] The implementation principle of this embodiment is as follows: the connection method between multiple positive electrode layers 211 and the controller enables the device to accurately determine which part of the glass fiber bundle is broken, which improves the efficiency of fault diagnosis and further ensures the stability and safety of fiber bundle delivery, which is a significant improvement compared with the prior art.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
