Abstract
Description
Technical Field
[0001] The present invention belongs to the technical fields of optical cable manufacturing and intelligent manufacturing, and particularly relates to an optical fiber pay-off device, a pay-off method, and an optical fiber coloring machine including the same. Background Art
[0002] With the development of optical cable manufacturing technology, the requirements for optical cable manufacturing are getting higher and higher. Among them, as an important link in the optical cable manufacturing process, the optical fiber coloring machine is required to control the optical fiber to be pulled out from the pay-off spool according to the winding and unwinding method for coloring, and then received on the optical fiber spool after coloring.
[0003] The existing process is that after the optical fiber is payed off, it passes through mechanical structures such as a traction wheel, a dancer wheel, and a fixed wheel, then enters the coloring die for coloring, and then passes through a curing furnace for curing, traction, and the take-up dancer wheel and finally is received on the spool. From the current process and statistical data, the optical fiber breakage rate is mainly caused by two aspects. On the one hand, when the optical fiber is payed off, it will pass through various mechanical structures, and the mechanical structures will generate a certain radial force on the optical fiber. If the optical fiber on the optical fiber spool is not neatly arranged or the wiring quality of the optical fiber deteriorates after transportation, it will lead to changes in the tension and pay-off path during the optical fiber pay-off process, and further lead to an increase in the radial force of the mechanical structure on the optical fiber, resulting in fiber breakage. On the other hand, when applying coating ink in the die, since the optical fiber passing through the die will increase the resistance, and at the same time, the ink temperature, pressure, and flow rate will affect the resistance size and are unstable, which will also lead to fiber breakage.
[0004] At present, in order to control the problem of uneven pay-off tension of the optical fiber, the existing optical fiber coloring machine generally adopts a dancer wheel at the pay-off end to buffer the pay-off tension, and it is necessary to adjust the center distance between the dancer wheel and the fixed wheel to be consistent. The mechanical maintenance engineer needs to adjust the cooperation degree of the corresponding multiple gear train bearings, the electrical maintenance engineer also needs to adjust the pay-off PID parameters, and the operator needs to adjust parameters such as the pay-off pitch. While ensuring high-speed speed synchronization, wire laying is carried out. However, due to the defects of the pay-off wire laying quality itself and the cooperation method of the multi-wheel system, there will be lag overshoot in the algorithm adjustment. After the coloring machine continuously speeds up, the original structure and algorithm can no longer reduce the fiber breakage rate, and it is necessary to frequently maintain the structural stability and program parameters. Summary of the Invention
[0005] In view of one or more of the above-mentioned defects or improvement requirements in the prior art, the present invention provides an optical fiber pay-off device, a pay-off method, and an optical fiber coloring machine including the same, which can automatically control the pay-off speed and pay-off tension of the optical fiber, reduce the maintenance cost and fiber breakage rate, and provide a guarantee for improving the product production speed.
[0006] To achieve the above object, in one aspect of the present invention, an optical fiber pay-off device is provided, which includes a pay-off mechanism, a displacement detection mechanism, a first fixed wheel, a tension detection mechanism, a traction mechanism, and a control system;
[0007] The wire pay-off mechanism is provided with a support assembly, a wire pay-off rotating assembly and a wire arranging and moving assembly; the support assembly is slidably arranged on the wire arranging and moving assembly and is used for installing an optical fiber reel, and the wire pay-off rotating assembly is arranged on the support assembly;
[0008] The first fixed pulley is arranged on one side of the wire pay-off mechanism; the tension detection mechanism is arranged on the fixed pulley to detect the tension of the optical fiber when passing through the fixed pulley;
[0009] The displacement detection mechanism is arranged between the wire pay-off mechanism and the fixed pulley and is used for detecting the wire pay-off position of the optical fiber;
[0010] The traction mechanism is arranged downstream of the fixed pulley to provide a certain traction speed for the optical fiber;

[0012] As a further improvement of the present invention, the displacement detection mechanism is an opposed sensor; the opposed sensor includes a light source emitter and a light source receiver which are arranged opposite to each other and at intervals, the light source emitter can emit a surface light source, the optical fiber can pass through the surface light source, the light source receiver receives the surface light source, and obtains the position when the optical fiber passes through according to the light intensity of the surface light source.
[0013] As a further improvement of the present invention, the surface light source is perpendicular to the optical fiber when passing through the surface light source.
[0014] As a further improvement of the present invention, the axis of the fixed pulley is parallel to the axis of the reel, and the wire pay-off direction of the optical fiber between the fixed pulley and the reel is perpendicular to the axis direction of the reel.
[0015] As a further improvement of the present invention, the control system calculates the real-time wire pay-off speed of the optical fiber according to the real-time tension value fed back by the tension detection mechanism and through the following formula:
[0016]
[0017] Wherein, V2 is the real-time wire pay-off speed of the optical fiber, V1 is the traction wire speed of the traction mechanism; F2 is the optical fiber tension, S is the cross-sectional area of the optical fiber, E is the Young's modulus of the optical fiber, and T is the wire pay-off time.
[0018] As a further improvement of the present invention, the support assembly includes a first support base and a second support base which are arranged at intervals. The first support base and the second support base are respectively slidably connected to the wire arrangement moving assembly, and can slide relative to each other and lock the relative sliding to adjust the support distance according to the width of the coil.
[0019] Another aspect of the present invention provides an optical fiber unwinding method, including the following steps:

The control system calculates the position offset of the optical fiber unwinding and the actual unwinding speed, and correspondingly adjusts the unwinding speed of the unwinding rotating assembly and the wire arrangement speed of the wire arrangement moving assembly.
[0023] As a further improvement of the present invention, when the unwinding position of the optical fiber is offset, if the offset direction is the same as the real-time moving direction of the coil, the wire arrangement speed of the wire arrangement moving assembly is correspondingly reduced according to the offset amount; if the offset direction is opposite to the real-time moving direction of the coil, the wire arrangement speed of the wire arrangement moving assembly is correspondingly increased according to the offset amount.
[0024] As a further improvement of the present invention, a deviation range of the optical fiber unwinding position and the unwinding tension is set in the control system, and when the deviation range is exceeded, the unwinding speed of the unwinding rotating assembly and the wire arrangement speed of the wire arrangement moving assembly are adjusted.

[0041] Embodiment:
[0042] Please refer to Figure 1 , the optical fiber coloring machine in the preferred embodiment of the present invention includes a wire feeding device, a coloring device 6, a curing device 7 and a wire winding device 8 arranged in sequence; wherein, after the bare optical fiber 9 is released by the wire feeding device, the optical fiber 9 is colored by the coloring device 6, and the colored optical fiber 9 is cured by the curing device 7, and then the colored optical fiber 9 is wound and stored by the wire winding device 8.
[0043] Specifically, the wire feeding device in the preferred embodiment includes a wire feeding mechanism 1, a displacement detection mechanism, a tension detection mechanism, a first fixed pulley 3 and a traction pulley 5.
[0044] Among them, the wire feeding mechanism 1 includes a base 101, a support assembly 102, a wire feeding rotation assembly and a wire arranging movement assembly; wherein, the base 101 provides space for the installation of each component in the wire feeding mechanism 1; the support assembly 102 includes a first support seat and a second support seat which are relatively spaced apart, and support shafts are respectively arranged on the opposite sides of the first support seat and the second support seat to support and install the optical fiber spool 10 by inserting the two support shafts into the hollow shaft of the optical fiber spool 10 respectively.
[0045] Furthermore, the wire feeding rotation assembly is fixedly arranged on the support assembly 102 and includes a wire feeding servo motor, so as to drive the optical fiber spool 10 installed on the support assembly 102 to rotate along its own axis by the wire feeding servo motor, and the optical fiber 9 wound on the spool 10 rotates and unwinds along with the spool 10, thereby realizing the wire feeding of the optical fiber 9.
[0046] Furthermore, as Figure 2As shown in the figure, the cable laying movement assembly includes a guide rail 103, a slider 104 and a cable laying servo motor. The guide rail 103 is arranged on the base 101 and is set in pairs at intervals of two. The extending direction of the guide rail 103 is consistent with the axial direction after the fiber optic spool 10 is installed on the support assembly 102. The slider 104 is arranged in matching with the two guide rails 103 and is arranged at the bottom of the support assembly 102. At the same time, the cable laying servo motor is connected to the slider 104, so that the slider 104 drives the support assembly 102 to move back and forth along the extending direction of the guide rail 103 under the drive of the cable laying servo motor, and further drives the spool 10 installed on the support assembly 102 to move back and forth along its own axis, ensuring that the laying path of the optical fiber 9 when leaving the spool 10 is perpendicular to the axis of the spool 10, so as to avoid the optical fiber 9 breaking due to a large radial force when leaving the spool 10.
[0047] Preferably, the first support seat and the second support seat are respectively slidably connected to the cable laying movement assembly and can slide relative to each other to adjust the support distance between the two support seats according to the width of the spool 10, and after adjustment, the relative sliding between the first support seat and the second support seat is locked by a locking member to ensure the reliability of the support for the spool 10.
[0048] It can be understood that the control system sets the rotation speed of the wire pay-off rotating assembly and the moving speed of the cable laying movement assembly according to the fiber diameter, the fiber coiling diameter, and the coiling pitch of the optical fiber 9 on the spool 10, etc., to keep the wire pay-off position, the wire pay-off tension, etc. of the optical fiber 9 unchanged during the wire pay-off process.
[0049] However, during actual operation, due to the irregular coiling of some of the optical fibers 9 on the spool 10 and the change of the coiling pitch, the actual wire pay-off speed of the optical fiber 9 does not match the system-set speed, resulting in the jitter of the optical fiber 9 during the wire pay-off process, the change of the wire pay-off tension, the wire pay-off position, etc., so that the optical fiber 9 cannot be perpendicular to the axis of the spool 10 when leaving the spool 10, causing the change of the wire pay-off tension, the wire pay-off position, etc. of the optical fiber 9, and further resulting in an increase in the radial force on the optical fiber 9 during the wire pay-off process and an increase in the fiber breakage rate.
[0050] Therefore, the present invention provides a displacement detection mechanism near one side of the wire pay-off mechanism 1 and arranges it on the wire pay-off path of the optical fiber 9 to detect the real-time wire pay-off position of the optical fiber 9, and connects the displacement detection mechanism to the control system to feed back the real-time wire pay-off position of the optical fiber 9 to the control system. The control system adjusts the moving speed of the cable laying movement assembly in real time according to the received information to timely adjust the wire pay-off position of the optical fiber 9, reduce the radial force on the optical fiber 9 caused by jitter and the change of the wire pay-off position, so that the optical fiber 9 is always at the center of the wheel surface of the first fixed pulley 3, and further reduce the fiber breakage rate of the optical fiber 9.
[0051] The displacement detection mechanism in the preferred embodiment is a through-beam sensor 2, which includes a light source transmitter and a light source receiver, wherein the light source transmitter can emit a surface light source to the light source receiver, and the light source receiver receives the surface light source. When the optical fiber 9 passes through the surface light source emitted by the light source transmitter, the light source receiver can determine the position of the optical fiber 9 by receiving the light source signal, light source intensity, etc., and the control system adjusts the moving speed of the cable moving component in real time according to the position change of the optical fiber 9.
[0052] Preferably, the surface light source emitted by the light source transmitter is arranged perpendicular to the optical fiber 9 when passing through the surface light source, so as to improve the sensitivity of the light source receiver.
[0053] It can be known that the optical fiber 9 is transparent before coloring. When the optical fiber 9 passes through the surface light source, the light source will be diffusely reflected on the surface of the optical fiber, thereby affecting the light intensity received at the corresponding position of the light source receiver. The specific position of the optical fiber 9 can be obtained by the light intensity obtained at the corresponding position.
[0054] Furthermore, in the preferred embodiment, the first fixed wheel 3 is arranged on the pay-off path of the optical fiber 9 and is arranged on the side of the displacement detection mechanism away from the pay-off mechanism 1, such as Figure 1 As shown in ; at the same time, a tension detection mechanism is provided on the first fixed wheel 3 to detect the tension of the optical fiber 9 when passing through the first fixed wheel 3, and the tension detection mechanism is connected to the control system to feed back the detected pay-off tension to the control system in real time. The control system controls the pay-off speed of the rotating assembly according to the real-time tension value to change the pay-off tension, thereby ensuring the stability of the tension of the optical fiber 9 during the pay-off process, reducing the radial force on the optical fiber 9, and reducing the fiber breakage rate.
[0055] Preferably, the axis of the first fixed wheel 3 and the axis of the reel 10 are set to be parallel to each other, and the pay-out direction of the optical fiber 9 between the first fixed wheel 3 and the reel 10 is set to be perpendicular to the axis direction of the reel 10 to avoid radial bending of the optical fiber 9 after leaving the reel 10, which would cause radial force.
[0056] It is known that the existing method for controlling the pay-off tension of the optical fiber 9 generally involves setting a dancer wheel in the pay-off device to balance the tension change through the swing of the dancer wheel. When the swing angle of the dancer wheel reaches a certain degree, the control system corrects the pay-off speed of the pay-off rotating component through the PID algorithm, thereby controlling the tension within a certain precision requirement range. However, the control precision and feedback sensitivity of this tension control method have relatively large limitations, and there are problems of hysteresis overshoot in algorithm adjustment, and the fiber breakage rate of the optical fiber 9 cannot be further reduced. Moreover, the pay-off system with a dancer wheel is generally a multi-wheel pay-off system. It is known that the more mechanical structures the optical fiber 9 passes through during the pay-off process, the more radial forces the optical fiber 9 is subjected to, and the faster the pay-off speed is adjusted, the greater the change in the radial force on the optical fiber 9, and the easier it is for the optical fiber to break.
[0057] In order to improve the detection accuracy of the tension detection mechanism and the control accuracy of the control system in the present invention, the tension detection mechanism is set as a tension sensor, and a traction mechanism is correspondingly set for the tension sensor, such as Figure 1 The traction mechanism shown includes a pay-off traction wheel 5, so as to traction the optical fiber 9 at a certain linear speed through the traction mechanism, and perform real-time conversion control between the change of the pay-off tension and the adjustment of the pay-off speed by means of the feedback and calculation of the high-speed servo motor encoder, and optimize the adjustment range of the algorithm.
[0058] Among them, there is the following relationship between the Young's modulus E of the optical fiber and the stress F1 and the strain ε:
[0059]
[0060] There is the following relationship between the stress F1 generated by the optical fiber and the tensile force F2 applied to the optical fiber and the cross-sectional area S of the optical fiber:
[0061]
[0062] There is the following relationship between the strain ε generated by the optical fiber and the traction linear speed V1 and the pay-off linear speed V2:
[0063] ε=(V1 - V2)T (3)
[0064] Among them, T is the pay-off time.
[0065] Assuming that the traction linear speed of the traction wheel 5 remains unchanged and the tensile force F2 applied to the optical fiber is the tension, then the pay-off linear speed V2 of the pay-off rotating component is:
[0066]
[0067] In actual use, it is only necessary to set the wire release speed of the wire release rotating component and the traction speed of the wire release traction wheel 5 in the control system. The control system can, according to the above formula, obtain the actual wire release speed of the optical fiber 9 based on the real-time tension detected by the tension sensor, and compare it with the set wire release speed of the wire release rotating component. If they are different or exceed a certain range, it will be adjusted in real time until the actual wire release speed of the optical fiber 9 is consistent with the set speed, and this range can be adjusted according to actual production requirements.
[0068] Meanwhile, the present invention also provides a second fixed wheel 4 between the first fixed wheel 3 and the traction wheel 5 to steer the traction direction of the optical fiber according to the machine layout requirements. That is, when the present invention releases the optical fiber 9, it only needs to pass through the first fixed wheel 3, the second fixed wheel 4 and the traction wheel 5, effectively reducing the number of mechanical structures that the optical fiber 9 passes through on the premise of being able to control and adjust the tension in real time, reducing the radial force on the optical fiber 9 and reducing the fiber breakage rate.
[0069] Furthermore, the present invention provides a wire release method corresponding to the above wire release device, which specifically includes the following steps:
[0070] (1) Preset the wire release speed of the wire release rotating component, the wire arrangement speed of the wire arrangement moving component, and the traction speed of the traction mechanism through the control system;
[0071] (2) Start the machine to release the optical fiber 9, and detect the wire release position and real-time tension value during the wire release process of the optical fiber 9 through the displacement detection mechanism and the tension detection mechanism;
[0072] (3) Feed back the detected wire release position fluctuation and tension fluctuation to the control system. The control system calculates the wire release position offset and the actual wire release speed of the optical fiber 9, and compares them with the preset values, and correspondingly adjusts the wire release speed of the wire release rotating component and the wire arrangement speed of the wire arrangement moving component.
[0073] As Figure 3 shown in the control flow of the control system. It can be known that when the wire release position of the optical fiber 9 deviates, if the deviation direction is the same as the real-time moving direction of the coil 10, the wire arrangement speed of the wire arrangement moving component is correspondingly reduced according to the offset; if the deviation direction is opposite to the real-time moving direction of the coil 10, the wire arrangement speed of the wire arrangement moving component is correspondingly increased according to the offset.
[0074] When the tension of the optical fiber 9 changes, the control system calculates the actual wire release speed of the optical fiber 9 according to formula (4), and compares it with the set wire release speed. If the actual wire release speed is faster, the wire release speed of the wire release rotating component is reduced until the actual wire release speed is consistent with the set value; if the actual wire release speed is slower, the wire release speed of the wire release rotating component is increased until the actual wire release speed is consistent with the set value.
[0075] It can be known that during actual setting, an acceptable deviation range between the detected value and the preset value can be set in the control system according to the wire laying requirements. If the deviation is large and exceeds the acceptable deviation range, the wire laying speed of the wire laying rotating component and the wire arranging speed of the wire arranging moving component are adjusted in real time according to the deviation ratio to be within the acceptable deviation range; if the deviation does not exceed the acceptable range, no adjustment is required and the operation continues at the set speed. The setting of the deviation range is adjusted according to actual production requirements.
[0076] Furthermore, the above wire laying device and wire laying method are used to lay the uncolored optical fiber, ensuring stable tension of the optical fiber during the wire laying process and reducing the fiber breakage rate. After the wire laying, the optical fiber is sent to the coloring device 6 for coloring the bare optical fiber, and after being cured by the curing device 7, the colored optical fiber is wound by the wire winding device 8.
[0077] The optical fiber wire laying device, wire laying method and optical fiber coloring machine including the same of the present invention have a simple structure and reasonable design. By optimizing the adjustment amplitude of the algorithm, the control effects of reducing the radial force of wire laying and wire arranging and stabilizing the tension are achieved, reducing the operation difficulty and the mechanical risk during long-term operation, providing an effective guarantee for improving the product production speed, and having the advantages of replacing manual labor, reliability, cost reduction and efficiency increase, and safety.
[0078] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
