Description

Technical Field

[0001] This invention relates to a stranding and cabling device, and more particularly to a symmetrically arranged multifunctional cabling device. Background Technology

[0002] Cables consist of multiple core wires, typically wound on a reel. The core wires are then released from the reel via a release frame. Depending on the number of core wires inside the cable, a single twisting machine requires a certain number of release frames, ranging from a minimum of 1 to a maximum of n. These release frames, combined with the twisting machine itself, form a complete single-twisting cabling machine. Traditionally, release frames for single-twisting cabling machines are dedicated to a single machine and cannot be reused. To improve the utilization rate of the cabling machine, the number of release frames is generally configured according to the maximum number of core wires required for a single twisting machine, resulting in a large number of machines, significant investment, and a large floor space. However, when producing cables with fewer core wires, some release frames remain idle, leading to wasted production capacity.

[0003] Furthermore, depending on the specifications of the finished stranded wire, actual production typically requires single-strand cabling machines and pay-off frames of varying sizes. Larger machines produce larger cables, while smaller machines produce smaller cables; each machine is dedicated to its specific purpose and cannot be used interchangeably with larger ones. Forcing their use would result in either a large machine producing small wires, leading to wasted electricity and low efficiency, or a small machine producing large wires with insufficient power and a small steering wheel radius, failing to meet product quality requirements and resulting in low efficiency. Therefore, large-size products require large-scale cabling and stranding machines, and small-size products require small-scale cabling and stranding machines; they cannot be mixed. This results in a large number of equipment investments and extremely high costs.

[0004] Furthermore, when the single-strand twisting machine rotates, all the core wires are twisted together at the same pitch or in the same direction of rotation. This makes it impossible to achieve layered twisting from the inner layer to the outer layer. There is no clear boundary between the inner and outer layers, and the outer core wires easily get stuck in the inner layer, while the inner core wires easily get stuck in the outer layer, resulting in strand skipping. To achieve layered twisting from the inner layer to the outer layer, each cable stranding machine must be equipped with a separate synchronous untwisting center pay-off machine, which further increases equipment investment and production space requirements, raising costs. Moreover, after a single twisting machine completes one stranding operation, the cable needs to be transferred to another cable stranding machine for multiple composite stranding operations to achieve layered twisting. This makes cable transfer inconvenient, involves many steps, and results in low production efficiency. Summary of the Invention The purpose of this invention is to provide a symmetrically arranged multifunctional cable-making device that can reduce the number of devices, lower costs, has multiple functions, and high production efficiency.

[0005] To achieve the above objectives, the present invention provides a symmetrically arranged multifunctional cabling device, including a first stranding cabling device, a second stranding cabling device, and multiple wire feeding frames. The wire feeding frames feed wires to the first stranding cabling device and / or the second stranding cabling device. The first stranding cabling device can receive the core wires fed out by the wire feeding frames and strand them into a cable with a certain pitch. The second stranding cabling device can receive the core wires fed out by the wire feeding frames and strand them into a cable with a certain pitch. The first stranding cabling device includes a first wire gathering mold arranged sequentially along the conveying direction of the core wires. The first rotating traction machine and the first stranding machine are included. The first gathering mold gathers all the core wires, the first rotating traction machine provides traction force to move the core wires, and the first stranding machine drives the core wires to strand or untwist. The second stranding machine includes a second gathering mold, a second rotating traction machine, and a second stranding machine arranged sequentially along the conveying direction of the core wires. The second gathering mold gathers all the core wires, the second rotating traction machine provides traction force to move the core wires, and the second stranding machine drives all the core wires to strand into a cable with a certain pitch.

[0006] Compared with the prior art, the present invention arranges the first wire gathering mold, the first rotary traction machine, and the first stranding machine sequentially along the conveying direction of the core wire, and arranges the second wire gathering mold, the second rotary traction machine, and the second stranding machine sequentially along the conveying direction of the core wire, thereby forming a first stranding and a second stranding device. Multiple pay-off frames are then placed between the first and second stranding devices. Therefore, the entire symmetrically arranged multi-functional cabling equipment can produce cables of one specification using the first stranding device and the pay-off frames, and can also produce cables of another specification using the second stranding device and the pay-off frames, thus producing cables of different specifications on a single device, offering diverse functions. Alternatively, some pay-off frames can be used in conjunction with the first stranding device, while other pay-off frames can be used in conjunction with the second stranding device, allowing both to be performed simultaneously, improving equipment utilization, thereby increasing production efficiency and reducing production costs. Furthermore, the first stranding and cabling device and the second stranding and cabling device can share the same pay-off frame, avoiding the need to prepare multiple pay-off frames for different stranding and cabling devices, effectively reducing the number of pay-off frames and further reducing production costs.

[0007] Preferably, in the first production mode, the symmetrically arranged multi-functional cabling equipment receives part or all of the core wires released from the wire release frame and twists them into a cable with a certain pitch, while the second stranding cabling device stops; or, the second stranding cabling device receives part or all of the core wires released from the wire release frame and twists them into a cable with a certain pitch, while the first stranding cabling device stops.

[0008] Preferably, in the second production mode, the symmetrically arranged multi-functional cable forming equipment receives a portion of the core wires released from the wire release frame and twists them into a cable with a certain pitch; at the same time, the second stranding cable forming device receives another portion of the core wires released from the wire release frame and twists them into a cable with a certain pitch.

[0009] Preferably, the first stranding device can untwist the cable and output the cable to the second stranding device; the second stranding device can simultaneously receive the cable from the pay-off frame and the first stranding device and strand it into a composite cable. This allows the first stranding device to be used as an untwist pay-off machine and output core wires to the second stranding device, where they are then stranded together with the core wires from the pay-off frame on the second stranding device to achieve composite stranding, producing a cable of another specification and increasing the equipment's functionality.

[0010] Preferably, all the wire feeding frames are disposed between the first stranding and cabling device and the second stranding and cabling device. This allows the wire feeding frames to both the first and second stranding and cabling devices, enabling them to be shared, improving the utilization rate of the wire feeding frames, reducing the number of devices, and lowering production costs.

[0011] Preferably, both the first and second stranding machines include a stranding mechanism and a take-up and release mechanism. The stranding mechanism strands the core wires into a cable with a certain pitch; the take-up and release mechanism takes up the cable.

[0012] Specifically, the take-up and unwinding mechanism includes a spool, a support, a rotating shaft, and a first servo motor. The rotating shaft is horizontally rotatably mounted on the support, and the spool is connected to the rotating shaft. The first servo motor drives the rotating shaft to rotate, thereby causing the spool to rotate. By using the first servo motor to drive the spool, the take-up and unwinding mechanism can automatically take up or unwind the wire.

[0013] Specifically, the stranding mechanism includes a cantilever, a support, a turntable, a drive shaft, a second servo motor, a first guide wheel, a second guide wheel, and a third guide wheel. The drive shaft is horizontally rotatably mounted on the support and concentrically fixedly connected to the turntable. One end of the drive shaft is fixedly connected to the rotating shaft of the rotating traction machine of the stranding device. One end of the cantilever is connected to the outer periphery of one side of the turntable, and the third guide wheel is pivotally connected to the other end of the cantilever. The second servo motor drives the drive shaft to rotate, so that the other end of the cantilever rotates around the outer periphery of the coil and the rotating shaft of the rotating traction machine of the stranding device rotates. The drive shaft has a central hole passing through both ends. The first guide wheel is pivotally connected to the turntable and offset from the central hole. The outer periphery of the first guide wheel is tangent to the central axis of the central hole. The second guide wheel is pivotally connected to the turntable and located on the outer periphery of the first guide wheel. The core wire passes through the central hole, the first guide wheel, the second guide wheel, and the third guide wheel and is wound around the coil. The cantilever can be driven to rotate by the second servo motor, which allows the cantilever to rotate around the reel, thereby collecting the cable onto or releasing it from the reel. It can also be used to twist or untwist the cable.

[0014] Preferably, the first stranding and cabling device further includes a first wrapping machine, which is disposed after the first cable gathering mold to wrap the cable; the second stranding and cabling device further includes a second wrapping machine, which is disposed after the second cable gathering mold to wrap the cable. By adding wrapping machines to the first and second stranding and cabling devices, both devices acquire wrapping functionality, thereby increasing the device's functional versatility and utilization rate.

[0015] Preferably, the first stranding and cabling device further includes a first splitter plate, which is disposed between the first wire gathering mold and the wire feeding frame to position the core wires; the second stranding and cabling device further includes a second splitter plate, which is disposed between the second wire gathering mold and the wire feeding frame to position the core wires. By setting the splitter plate, the core wires can be automatically aligned before entering the wire gathering mold, ensuring the smoothness and uniformity of the position of each core wire entering the wire gathering mold.

[0027] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please see Figures 1 to 3 The symmetrically arranged multifunctional cabling equipment 100 of the present invention includes a first stranded cable forming device 1, a second stranded cable forming device 2, and multiple cable feeding racks 3. All cable feeding racks 3 are disposed between the first stranded cable forming device 1 and the second stranded cable forming device 2. The cable feeding racks 3 feed cables to the first stranded cable forming device 1 and / or the second stranded cable forming device 2. In this embodiment, the first stranded cable forming device 1 is located on the left side of all cable feeding racks 3, and the second stranded cable forming device 2 is located on the right side of all cable feeding racks 3. The first stranded cable forming device 1 and the second stranded cable forming device 2 are symmetrically arranged. This allows all cable feeding racks 3 to feed cables to either the first stranded cable forming device 1 or the second stranded cable forming device 2, achieving shared use, improving the utilization rate of the cable feeding racks 3, reducing the number of devices, and lowering production costs. Of course, as... Figure 10 As shown, the first stranding and cabling device 1 and the second stranding and cabling device 2 can also be arranged side by side, and the core wires are provided by multiple pay-off frames 3 in front. The pay-off frames 3 can be powered untwisting pay-off frames or static pay-off frames. In addition, in this embodiment, the first stranding and cabling device 1 is of small specification / size and is used to produce small specification cables, while the second stranding and cabling device 2 is of large specification / size and is used to produce large specification cables. The first stranding and cabling device 1 can receive the core wires 200 released from the pay-off frames 3 and strand them into cables 300 with a certain pitch. The second stranding and cabling device 2 can receive the core wires 200 released from the pay-off frames 3 and strand them into cables 300 with a certain pitch. The first stranding and cabling device 1 includes a first gathering mold 11, a first rotary traction machine 12, and a first stranding and cabling machine 13 arranged sequentially along the conveying direction of the core wires 200. After the core wires 200 are released from the pay-off frame 3, they pass sequentially through the first gathering mold 11, the first rotary traction machine 12, and the first stranding and cabling machine 13. The first gathering mold 11 gathers all the core wires 200. The first rotary traction machine 12 provides traction force to move the core wires 200 and keeps the cable wound at a uniform speed. The first stranding and cabling machine 13 drives the core wires 200 to twist or untwist. The second stranding and cabling device 2 includes a second gathering mold 21, a second rotary traction machine 22, and a second stranding and cabling machine 23 arranged sequentially along the conveying direction of the core wires 200. After the core wires 200 are released from the pay-off frame 3, they pass sequentially through the second gathering mold 21, the second rotary traction machine 22, and the second stranding and cabling machine 23. The second gathering mold 21 gathers all the core wires 200, and the second rotary traction machine 22 provides traction force to move the core wires 200 and keeps the cable wound at a uniform speed after cabling. The second stranding machine 23 drives all the core wires 200 to strand into a cable 300 with a certain pitch.

[0029] Please see Figures 3 to 5The first stranding machine 13 and the second stranding machine 23 have the same structure and layout, only differing in specifications / size. The following description focuses on the structure of the first stranding machine 13. The first stranding machine 13 includes a stranding mechanism 131 and a take-up / release mechanism 132. The stranding mechanism 131 strands the core wires 200 into a cable 300 with a certain pitch. The take-up / release mechanism 132 takes up the cable 300. The stranding mechanism 131 is located between the first rotary traction machine 12 and the take-up / release mechanism 132. Specifically, the take-up / release mechanism 132 includes a reel 1321, a support 1322, a rotating shaft 1323, and a first servo motor 1324. The rotating shaft 1323 is horizontally rotatably mounted on the support 1322. The reel 1321 is connected to the rotating shaft 1323. The first servo motor 1324 drives the rotating shaft 1323 to rotate, thereby rotating the reel 1321. The first servo motor 1324 drives the wire reel 1321, enabling the take-up and release mechanism 132 to automatically take up or release the wire. The first stranding machine 13 also includes a translation drive mechanism 133, which drives the take-up and release mechanism 132 to move along the conveying direction of the core wire 200, so as to arrange the cable 300 during take-up or release. The stranding mechanism 131 includes a cantilever 1311, a support 1312, a turntable 1313, a drive shaft 1314, a second servo motor 1315, a first guide wheel 1316, a second guide wheel 1317, and a third guide wheel 1318. The drive shaft 1314 is horizontally rotatably mounted on the support 1312 and is concentrically fixedly connected to the turntable 1313. One end of the drive shaft 1314 is fixedly connected to the rotating shaft 122a of the first rotary traction machine 12 via a coupling 16. One end of the cantilever 1311 is fixedly connected to the outer periphery of one side of the turntable 1313, and the third guide wheel 1318 is pivotally connected to the other end of the cantilever 1311. The second servo motor 1315 drives the drive shaft 1314 to rotate, so that the other end of the cantilever 1311 rotates around the outer periphery of the coil 1321 and the rotation shaft 122a of the first rotary traction machine 12 rotates. The drive shaft 1314 is provided with a central hole 1314a that passes through both ends. The first guide wheel 1316 is pivotally connected to the turntable 1313 and offset from the central hole 1314a. The outer periphery of the first guide wheel 1316 is tangent to the central axis of the central hole 1314a. The second guide wheel 1317 is pivotally connected to the turntable 1313 and located on the outer periphery of the first guide wheel 1316. The core wire 200 passes through the central hole 1314a, the first guide wheel 1316, the second guide wheel 1317 and the third guide wheel 1318 and is wound around the coil 1321.The second servo motor 1315 drives the cantilever 1311 to rotate, which allows the cantilever 1311 to rotate around the reel 1321, thereby collecting the cable 300 onto or releasing it from the reel 1321. On the other hand, it can also twist or untwist the cable 300.

[0030] Please see Figure 3 and Figure 6 The first rotary traction machine 12 and the second rotary traction machine 22 have the same structure and layout, only differing in specifications / size. The following description focuses on the structure of the first rotary traction machine 12. The first rotary traction machine 12 includes a frame 121, a rotating body 122, a traction drive mechanism 123, a traction wheel 124, a tension wheel 125, a spring 126, and a sensor 127. The rotating body 122 is horizontally and rotatably mounted on the frame 121, and its rotation shaft 122a is connected to a coupling 16. The traction wheel 124 is pivotally connected to the rotating body 122, and the tension wheel 125 is pivotally connected to a slider 128. The slider 128 is slidably mounted on the frame 121 along the central axis of the rotating body 122, with a core wire sequentially surrounding the tension wheel 125 and the traction wheel 124. The spring 126 is positioned between the slider 128 and the frame 121. The traction drive mechanism 123 is mounted on the frame 121 and drives the traction wheel 124 to rotate, thereby tractioning the core wire. The sensor 127 is mounted on the frame 121 and is used to detect the movement distance of the tension wheel 125 or the slider, thereby controlling the take-up speed of the first stranding machine 13 through the control system, thus ensuring that the cable maintains a uniform winding speed after stranding. The structure of the first rotary traction machine 12 and the second rotary traction machine 22 in this solution is prior art, and its structure and working principle are well known to those skilled in the art, and will not be described in detail here.

[0031] For example Figures 1 to 3 As shown, the first stranding and cabling device 1 further includes a first wrapping machine 14, which is disposed between the first cable gathering mold 11 and the first rotary traction machine 12 to wrap the cable; the second stranding and cabling device 2 further includes a second wrapping machine 24, which is disposed between the second cable gathering mold 21 and the second rotary traction machine 22 to wrap the cable. The structures of the first wrapping machine 14 and the second wrapping machine 24 are the same and well known to those skilled in the art, and will not be described in detail here. By adding wrapping machines to the first stranding and cabling device 1 and the second stranding and cabling device 2, the first stranding and cabling device 1 and the second stranding and cabling device 2 are equipped with wrapping functions, thereby improving the functional versatility of the equipment and increasing its utilization rate.

[0032] For example Figures 1 to 3 As shown, the first stranding and cabling device 1 further includes a first splitter plate 15, which is disposed between the first wire gathering mold 11 and the wire feeding frame 3 to position the core wires 200; the second stranding and cabling device 2 further includes a second splitter plate 25, which is disposed between the second wire gathering mold 21 and the wire feeding frame 3 to position the core wires 200. By setting the splitter plate, the core wires 200 can be automatically aligned before entering the wire gathering mold, ensuring the smoothness and uniformity of the position of each core wire 200 entering the wire gathering mold.

[0033] In summary, the working principle of the symmetrically arranged multifunctional cabling device 100 of the present invention will be described in detail below: Please see Figure 7 When the symmetrically arranged multi-functional cabling equipment 100 is used in the first production mode, the second stranding cabling device 2 is stopped, and the first stranding cabling device 1 operates to produce small-diameter cables. The first wire gathering mold 11, the first rotary traction machine 12, the center hole 1314a of the stranding mechanism 131 of the first stranding cabling device 1, and the center axis of the coil 1321 of the take-up and release mechanism 132 of the first stranding cabling device 1 are coaxially arranged. A portion of the core wire 200 released from the release frame 3 passes sequentially through the first wire separating plate 15, the center hole 1314a of the first wire gathering mold 11, the first guide wheel 1316, the second guide wheel 1317, and the third guide wheel 1318 and surrounds the coil 1321. During operation, the wire feeding frame 3 starts feeding the wire, the first rotary traction machine 12 starts moving the core wire, the wire take-up and feeding mechanism 132 starts taking the wire, the first stranding machine 13 starts stranding all the core wires 200 after passing through the first wire gathering mold 11, and the cantilever 1311 winds the stranded cable 300 onto the reel 1321. Please refer to [link / reference]. Figure 8 Similarly, the first stranding and cabling device 1 can be stopped, while the second stranding and cabling device 2 can operate to produce large-diameter cables. Simply thread all or part of the core wires 200 released from the wire release frame 3 onto the second stranding and cabling device 2, and the second stranding and cabling device 2 will then perform stranding and take-up. The working principle is the same as that of the first stranding and cabling device 1.

[0034] Please see Figure 9When the symmetrically arranged multi-functional cabling equipment 100 uses the second production mode, the first stranding cabling device 1 receives a portion of the core wires 200 released from the wire release frame 3 and strands them into a cable 300 with a certain pitch; at the same time, the second stranding cabling device 2 receives another portion of the core wires 200 released from the wire release frame 3 and strands them into a cable 300 with a certain pitch. The two work simultaneously without affecting each other.

[0035] Please see Figure 10 When the symmetrically arranged multi-functional cabling equipment 100 uses the third production mode, the first stranding cabling device 1 acts as an untwisting and releasing device to untwist the cable and output the cable 300 to the second stranding cabling device 2. The second stranding cabling device 2 can simultaneously receive the cable 300 released from the release frame 3 and the first stranding cabling device 1 and strand it into a composite cable 400. This allows the first stranding cabling device 1 to be used as an untwisting and releasing device and output core wires 200 to the second stranding cabling device 2, which are then stranded together with the core wires 200 released from the release frame 3 on the second stranding cabling device 2 to achieve composite stranding, producing a cable of another specification and increasing the functionality of the equipment. For example, when producing a two-layer composite cable 400, the inner and outer layers of the composite cable 400 have different pitches. The first production mode of the symmetrically arranged multi-functional cabling equipment 100 can be utilized, in which the first stranding cabling device 1 is operated while the second stranding cabling device 2 is stopped, thereby producing a cable 300 with a certain pitch, which is then held on the reel 1321 of the first stranding cabling device 1. Next, the symmetrically arranged multi-functional cabling equipment 100 is switched to a third production mode, where the reel 1321 of the first stranding cabling device 1 rotates in the opposite direction to release the stranded small-diameter cable 300, which is then conveyed towards the second stranding cabling device 2. Simultaneously, the cable release frame 3 releases multiple core wires 200. The cable 300 passes through the second splitter plate 25 and then through the center of the second cable-gathering mold 21. The core wires 200 are arranged around the cable. These core wires 200 pass evenly through the second splitter plate 25 and then through the second cable-gathering mold 21. Then, the stranding mechanism 131 of the second stranding cabling device 2 strands these core wires 200, so that the core wires 200 are stranded at another pitch to the outer layer of the cable 300, thereby forming a large-size composite cable 400 with an inner and outer layer. Finally, the cantilever 1311 of the second stranding cabling device 2 cooperates with the reel 1321 to take in the composite cable 400. By stranding different pitches or setting the stranding direction of the inner and outer layers to opposite directions, the core wires 200 of the large-size composite cable 400 are less likely to disperse, improving the quality of the cable.

[0036] Compared with the prior art, the present invention forms a first stranding device 1 and a second stranding device 2 by arranging the first wire gathering mold 11, the first rotary traction machine 12, and the first stranding machine 13 sequentially along the conveying direction of the core wire 200, and by arranging the second wire gathering mold 21, the second rotary traction machine 22, and the second stranding machine 23 sequentially along the conveying direction of the core wire 200. Multiple wire feeding frames 3 are then placed between the first stranding device 1 and the second stranding device 2, thus achieving overall symmetry. The multi-functional cabling equipment 100 can produce cables of one specification using the first stranding cabling device 1 and the pay-off frame 3, and can also produce cables of another specification using the second stranding cabling device 2 and the pay-off frame 3, thus producing cables of different specifications on a single machine, offering diverse functions. Alternatively, some pay-off frames 3 can be used in conjunction with the first stranding cabling device 1, while others can be used in conjunction with the second stranding cabling device 2, allowing both to operate simultaneously, improving equipment utilization, increasing production efficiency, and reducing production costs. Furthermore, the first stranding cabling device 1 and the second stranding cabling device 2 can share the pay-off frame 3, avoiding the need for multiple pay-off frames 3 for different stranding cabling devices, effectively reducing the number of pay-off frames 3, and further lowering production costs.

[0037] In this embodiment, the first stranding device 1 and the second stranding device 2 are single stranding machines. Similarly, the first stranding device 1 and the second stranding device 2 can also be double stranding machines (forming two pitches with one rotation), and the working principle is the same as in the above embodiment. The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made within the scope of the present invention are still within the scope of the present invention.
