Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical cable manufacturing, in particular to a cabling grease alarm system and method. BACKGROUND

[0002] In the cabling process of optical cable, a plurality of optical fiber jackets are twisted around a central reinforcing element to form a cable core. In order to ensure that the cable core has longitudinal water-blocking performance, an oil filling method is generally used for longitudinal water-blocking of the optical cable.

[0003] The oil filling device first places the reinforcing element in the oil filling mold, then fills the oil on the surface of the reinforcing element and the jacket, and then twists the jacket around the reinforcing element.

[0004] In the existing patent cabling grease coating device (CN202120983595.2), the cable grease is filled on the surface of the central reinforcing element by a certain pressure, and under the action of gravity, the cable grease is uniformly distributed on the surface of the reinforcing element, ensuring that the filling is sufficient. At the same time, the jacket is twisted around the reinforcing element to form a continuous water-blocking section on the cable core, meeting the water penetration performance of the optical cable.

[0005] However, if the oil filling method of the cable core causes the oil to be blocked, the entire cable core will have no oil, which will eventually cause the optical cable in the sheath to penetrate water, affecting the water-blocking performance of the optical cable, and thus affecting the quality of the optical cable. SUMMARY

[0006] The technical problem solved by the present application is to provide a cabling grease alarm system and method that can monitor the distribution of oil on the surface of the central reinforcing element in real time, determine whether the oil flows out through the digital signal of the photoelectric switch and the PLC controller, and ensure the normal operation of the cabling grease filling. The alarm system can determine when the oil filling stops through the buzzing sound, which facilitates timely inspection of the oil filling status of the cabling process, meets the water penetration performance requirements of the cable core, and reduces the labor intensity of workers.

[0007] To solve the above technical problems, one technical solution adopted by the present application is to provide a cabling grease alarm system, comprising: a cabling assembly and a monitoring alarm assembly.

[0008] The cabling assembly comprises: a cabling twisting table, a reinforcing element, a support and an oil spraying gun,

[0009] The oil spraying gun is installed on the support and sprays oil on the surface of the reinforcing element. The reinforcing element moves through the support to the cabling twisting table and completes oil spraying before entering the cabling twisting table.

[0010] The monitoring alarm assembly comprises: a photoelectric switch, an alarm and a PLC controller,

[0011] The photoelectric switch is installed on a support, and the sensing side of the photoelectric switch faces the surface of the reinforcing member for generating a photoelectric digital signal when the greasing condition of the reinforcing member is detected;

[0012] The PLC controller is connected with the photoelectric switch and the alarm, and the PLC controller judges whether the greasing is normal based on the greasing amount of the surface of the reinforcing member obtained from the feedback digital signal of the photoelectric switch:

[0013] If the greasing amount of the surface of the reinforcing member is normal, the PLC controller sends a signal for continuing the action to control the cabling assembly to continue the cabling action;

[0014] If the greasing amount of the surface of the reinforcing member is not detected continuously, the PLC controller controls the alarm to alarm, and sends a signal for stopping the action to control the cabling assembly to stop the cabling action.

[0015] In a preferred embodiment of the present application, the alarm comprises a buzzer for emitting a buzzing sound when the alarm is started.

[0016] In a preferred embodiment of the present application, the monitoring and alarming assembly further comprises a trigger connected with the PLC controller, and the trigger is used for sending an instruction to control the cabling assembly when the PLC controller sends a signal for stopping the action.

[0017] In a preferred embodiment of the present application, the trigger is a DB105 trigger.

[0018] In a preferred embodiment of the present application, the photoelectric switch is an Omron E3JK-DS30M1 photoelectric sensor.

[0019] In a preferred embodiment of the present application, the PLC controller is an FX3U series controller.

[0020] To solve the above technical problems, another technical solution adopted by the present application is to provide a cabling greasing alarm method, which adopts the cabling greasing alarm system, sets the cabling speed as 20-80 m / min, and comprises the following steps:

[0021] a. Normal working:

[0022] When the cabling speed is 20-80 m / min, the cabling assembly operates normally, the cabling greasing alarm system is started, and the photoelectric switch detects the greasing condition of the surface of the reinforcing member according to the cabling speed;

[0023] b. Alarming working:

[0024] When the photoelectric switch does not detect the greasing of the surface of the reinforcing member, the photoelectric switch judges the detected signal:

[0025] b1, if the grease is detected within 5s, the cabling assembly continues normal operation;

[0026] b2, if the grease is not detected for more than 5s, the monitoring alarm assembly is started, the buzzer sends a beeping sound according to the instruction sent by the photoelectric switch, and the PLC controller sends a signal according to the received instruction to control the whole cabling process to be stopped by the trigger;

[0027] b3, the operator checks in time according to the beeping sound whether the grease coating fails, and if the grease filling fails, the operator needs to adjust the grease coating amount for normal production of the cable core;

[0028] c, not working:

[0029] When the cabling speed is lower than 20 m / min, the oil output is constant, the oil droplets cannot be detected, and the cabling grease alarm system does not work.

[0030] In a preferred embodiment of the present application, the cabling speed of the large-core-count optical cable is 25-35 m / min, and the cabling speed of the small-core-count optical cable is 40-80 m / min.

[0031] In a preferred embodiment of the present application, the detection distance of the photoelectric switch is 0.5-10 cm, and when the photoelectric switch is in a closed state, the cabling grease alarm system is in an armed state.

[0032] In a preferred embodiment of the present application, the buzzer starts to alarm and works all the time, and when the operator cancels the alarm, the buzzer ends the work and enters the next armed state to wait for the next alarm.

[0033] The beneficial effects of the present application are that the cabling grease alarm system and method can monitor the distribution of the grease on the surface of the central reinforcing member in real time, determine whether the grease flows out through the digital signal of the photoelectric switch and the PLC controller, and ensure the normal operation of the cabling grease filling; the buzzer of the alarm system can determine the stop of the grease filling, facilitate the timely inspection of the grease filling status of the cabling process, meet the water permeability performance requirements of the cable core, and reduce the labor intensity of the workers.
