For example, various ultraviolet curable resins have been developed to improve the bending loss of optical fibers. The optimum coating heating temperature varies depending on the type of these resins. In the optical fiber connection workshop, it is necessary to change the set temperature according to various types of coating materials, old and new.

  The communication unit 11 in the coating removal apparatus 2 illustrated in FIG. 1 is connected to the power cord 4 and the control unit 12. The communication unit 11 receives and acquires information from the communication unit 34 of the fusion splicing device 3 via the power cord 4 and outputs the information to the control unit 12. Further, the communication unit 11 transmits various information output from the control unit 12 to the communication unit 34 of the fusion splicing device 3 via the power cord 4. The information from the communication unit 34 of the fusion splicing device 3 includes, for example, optical fiber type information for specifying an optical fiber type selected by the user from a plurality of optical fiber types described later. The communication unit 11 receives the covering heating condition information as information based on the optical fiber type information from the fusion splicing device 3.

  The control unit 12 performs control based on various arithmetic processes and the like based on various information output from the communication unit 11 and the maintenance information acquisition unit 15 and various information stored in the storage unit 13. For example, the heating temperature and / or heating time of the heater 14 is controlled based on the set covering heating condition stored in the storage unit 13, or the communication unit 11 is based on the optical fiber type information from the fusion splicing device 3. Is acquired, the coating heating condition included in the information is stored in the storage unit 13. Further, when the set covering heating condition is already stored in the storage unit 13, the communication unit 11 further acquires information from the fusion splicing device 3 and newly sets the set covering heating condition. The unit 12 rewrites the set covering heating condition already stored in the storage unit 13 and changes the set covering heating condition.

The storage unit 13 stores various information obtained by the control unit 12. The control unit 12 writes and stores various information in the storage unit 13 as necessary, and reads out various information stored in the storage unit 13.

  For example, the heater 14 performs coating heating of the optical fiber using the set coating heating conditions stored in the storage unit 13 and read out by the control unit 12. In addition, the heater 14 can perform coating heating under a plurality of conditions according to information based on optical fiber type information that identifies an optical fiber type selected by a user (operator) from a plurality of optical fiber types. . Furthermore, since the heater 14 uses information based on the optical fiber type information, it is possible to perform coating heating under a plurality of conditions according to the optical fiber type information. The control unit 12 can set a plurality of coating heating conditions as set coating heating conditions in accordance with information based on the optical fiber type information from the fusion splicing device 3.

  The maintenance information acquisition unit 15 acquires maintenance information such as the remaining amount of the built-in battery, the number of times of charging / discharging of the built-in battery, the number of uses of the coating removal blade 24, and the occurrence of an abnormality. The maintenance information acquisition unit 15 outputs the acquired maintenance information to the control unit 12. The maintenance information acquisition unit 15 only needs to acquire at least one maintenance information among the remaining amount of the internal battery, the number of times of charging / discharging of the internal battery, the number of times of use of the coating removal blade 24, and the occurrence of abnormality. The control unit 12 outputs information based on the output maintenance information to the communication unit 11, and the communication unit 11 transmits information based on the maintenance information acquired by the maintenance information acquisition unit 15 to the fusion splicing device 3. Further, the storage unit 13 stores an ID number that is identification information of the coating removal apparatus 2. When outputting the maintenance information to the communication unit 11, the control unit 12 reads the identification information stored in the storage unit 13 and outputs the identification information together with the maintenance information to the communication unit 11. The communication unit 11 transmits information based on the identification information to the fusion splicing device 3 together with information based on the maintenance information.

  The communication unit 11 receives information from the fusion splicing device 3 based on a buzzer sound volume setting instruction for the sheath removal device 2.

The input unit 31 in the fusion splicing device 3 inputs various information according to the operation of the input key 43. The input unit 31 outputs various input information to the control unit 32.
The control unit 32 transmits various information input from the input unit 31 and various information transmitted from the communication unit 11 of the coating removal apparatus 2 via the power cord 4 and output from the communication unit 34 of the fusion splicing apparatus 3. Based on this, various setting processes are performed. The control unit 32 outputs various types of information to the storage unit 33, the communication unit 34, the output unit 35, and the like based on the results of these setting processes and the like.

  The storage unit 33 stores various information necessary for the fusion splicing of the optical fiber in the fusion splicing device 3 such as a connection program described later, and various information necessary for the sheath removal of the coating removing device 2. In addition, the control unit 32 writes various information in the storage unit 33 and stores the various information as necessary, or reads out various information stored in the storage unit 33.

  The fusion splicing device 3 stores a plurality of connection programs corresponding to the types of optical fibers in the storage unit 33. These plurality of connection programs include, for example, optical fiber type information, and the optical fiber type information includes coating heating condition information. The control unit 32 specifies a connection program selected by the operator (a connection program being selected) from among a plurality of connection programs stored in the storage unit 33 using an input to the input unit 31 and is illustrated. The fusion splicing section is controlled and the fusion splicing is performed using the selected connection program.

  The communication unit 34 is connected to the power cord 4 and the control unit 32. The communication unit 34 outputs various information transmitted from the communication unit 11 of the coating removal apparatus 2 via the power cord 4 to the control unit 32. Further, the communication unit 34 transmits various information output from the control unit 32 to the communication unit 11 of the coating removal apparatus 2 via the power cord 4. The output unit 35 displays and outputs various types of information such as connection programs and maintenance information based on the information output from the control unit 32. For example, the fusion splicing device 3 receives information based on the maintenance information from the communication unit 11 of the coating removal device 2 and outputs the maintenance information from the output unit 35. The output unit 35 is, for example, a display monitor 42 described later, and the maintenance information is output to the display monitor 42. The fusion splicing device 3 uses the information based on the received maintenance information and outputs the maintenance information from the display monitor 42. Also, the fusion splicing device 3 uses the information based on the received identification information, and outputs the identification information of the coating removal device 2 from the display monitor 42.

  Further, the fusion splicing device 3 operates by receiving power from a commercial AC power supply. The sheath removing device 2 operates by receiving power supply from the fusion splicing device 3 via the power cord 4. The fusion splicing device 3 can also be switched from a commercial AC power source to a built-in battery and operated using the built-in battery as a power source. The coating removal apparatus 2 can also operate by using the built-in battery as a power source by switching the power supply from the fusion splicing apparatus 3 to the built-in battery.

  When the power source is switched from a commercial AC power source to a built-in battery, the fusion splicing device 3 performs a power saving operation in order to reduce power consumption of the built-in battery. Specifically, the display monitor 42 is turned off when there is no operation for a certain time, for example, 30 seconds.

  When the power source is switched from the commercial AC power source to the built-in battery in the fusion splicing device 3, the power removal operation is also performed in the coating removal device 2. When the power source is switched from the commercial AC power source to the built-in battery and the power saving mode is turned on, the fusion splicing device 3 transmits the power saving information to the sheath removal device 2 as information based on the power saving operation setting instruction. . The communication unit 11 of the sheath removal apparatus 2 receives the power saving information from the fusion splicing apparatus 3. The communication unit 11 outputs the received power saving information to the control unit 12. The control unit 12 issues a power saving operation setting instruction using the output power saving information. In a normal state where the setting instruction for the power saving operation is not performed, the control unit 12 preheats the heater 14 so that the heater 14 reaches the heating temperature in a short time when the coating of the optical fiber is removed. ing. In the power saving state in which the setting instruction for the power saving operation is performed, the control unit 12 performs the setting for stopping the preheating of the heater 14 when the coating removal apparatus 2 is not operated for a certain time, for example, 10 minutes. The coating removal apparatus 2 suppresses power consumption by stopping the preheating of the heater 14. The heater 14 controls the preheating of the heater 14 using the power saving information received by the communication unit 11.

  Here, the procedure of the coating removal of the optical fiber by the coating removal apparatus 2 will be described. When removing the coating of the optical fiber by the coating removal device 2, first, the operator brings the clamp portion 26 close to the base 21 and opens the lid member 23 provided on the base 21. The operator places the fiber holder 27 on the clamp portion 26 so that the end portion of the optical fiber is placed on the heater 14, and clamps the fiber holder 27 on the clamp portion 26.

  Then, the operator closes the lid member 23 and sandwiches the optical fiber between the heater 14 and the lid member 23. When the lid member 23 is closed, the coating removal blade 24 enters the coating of the optical fiber. When a sensor (not shown) detects that the lid member 23 is closed, the heater 14 starts heating the coating of the terminal portion removed by the optical fiber. Thereafter, the coating at the end portion of the optical fiber is heated at the heating temperature (set coating heating temperature) set by the control unit 12 for the heating time (set coating heating time) set by the control unit 12. After the set covering heating time has elapsed, for example, a buzzer sound is output from the buzzer sound output unit 16 to notify the operator that the preparation for extracting the covering has been completed. Then, when the operator moves the clamp part 26 in the direction away from the base 21, the coating on the end part of the heated and softened optical fiber is pulled out. In this way, the coating of the optical fiber is removed.

  Before the coating of the optical fiber is removed by the coating removal blade 24, the coating is heated at a coating heating temperature and / or a coating heating time at which the coating pulling force becomes small. For example, the optimum coating heating temperature at which the coating pulling force is minimized. It is necessary to heat the coating at (set coating heating temperature) and / or optimal coating heating time (set coating heating time). The optimum coating heating temperature is shown in FIG. 4 of JP-A-1-900003. The force with which the optical fiber is pulled out of the coating during coating removal varies with the coating heating temperature. When the coating pulling force is high, a large tension is applied to the optical fiber at the time of coating removal, and even if the optical fiber is broken or not broken during coating removal, the strength of the optical fiber is lowered and long-term reliability is lowered. Therefore, it is necessary to heat the coating at a coating heating temperature at which the coating pull-out force is reduced, more preferably at an optimum coating heating temperature at which the coating pull-out force is minimized.

  Even if the coating is heated at the optimum coating heating temperature, it takes several seconds to transfer the temperature to the inside of the coating. If the coating is removed without heat being transferred to the inside of the coating, the coating pulling force will increase, and the optical fiber will be broken during the coating removal or even if it does not break, the strength of the optical fiber will decrease and the long-term reliability will deteriorate. Occurs.

  Even if the coating is heated at the optimum coating heating temperature, if the heating time is longer than necessary, a problem may occur depending on the coating material. The coating material is pulverized by heating for a long time, and powder remains on the surface of the optical fiber after the coating is removed. The powder on the surface of the optical fiber glass that is not removed by cleaning burns during the fusion splicing and causes deterioration of the strength of the optical fiber.

  Next, coating heating conditions when removing the coating of the optical fiber will be described. When removing the coating of the optical fiber, a coating heating condition setting process for setting a coating heating condition for heating the coating of the optical fiber is performed. Hereinafter, the procedure of the covering heating condition setting process will be described with reference to FIG.

  As shown in FIG. 3, in the covering heating condition setting process, the control unit 32 determines whether or not the selection of the connection program has been confirmed (step S1). As a result, when the selection of the connection program is not finalized (step S1; NO), the coating heating condition setting process is terminated as it is.

  The storage unit 33 of the fusion splicing device 3 stores a plurality of connection programs for splicing optical fibers. Each of the plurality of connection programs is assigned a connection program number. When the operator selects a connection program, for example, as shown in FIG. 4, a plurality of connection program numbers (connection program numbers) and names (connections) are displayed on the display screen of the display monitor 42 in the fusion splicer 3. Program name) is displayed. The connection program name includes information for specifying the optical fiber to be spliced.

In the example shown in FIG. 4, five connection program numbers and connection program names are displayed.
The connection program name of the connection program number 1 is “NZ12 TYPE-P ITUTG655”.
The connection program name of the connection program number 2 is “SM4 TYPE-C ITUTG652”.
The connection program name of the connection program number 3 is “NZ12 TYPE-P ITUTG655”.
The connection program name of the connection program number 4 is “SM1 TYPE-A ITUTG652”.
The connection program name of the connection program number 5 is “MM4 TYPE-S ITUTG651”.

  In each connection program, the first character string represents the optical fiber classification and the number of cores, the second character string represents the type of optical fiber, and the third character string represents the standard number of the international standard ITU-T. . For example, in the connection program “NZ12 TYPE-P ITUTG655”, “NZ12” represents a 12-core optical fiber (tape-type optical fiber) classified as a non-zero dispersion shifted fiber, and “TYPE-P” “ITUTG655” represents the standard number G.655 of the international standard ITU-T for the optical fiber.

  For example, the operator can select and confirm the connection program by operating the input key 43 shown in FIG. In the example shown in FIG. 4, the connection program “NZ12 TYPE-P ITUTG655” where the cursor is located is selected. When the up key 43B or the down key 43D is operated from this state, the cursor moves up and down, and the selected connection program number is changed.

  When the cursor is positioned at a desired connection program number, the operator operates the enter key 43E. By operating the enter key 43E, the selection of the connection program where the cursor is located is confirmed. The input unit 31 inputs a series of input information to the input key 43 so far as optical fiber type information selected by a user (operator) from a plurality of optical fiber types, and outputs the information to the control unit 32. The optical fiber type information is information for specifying the optical fiber type. In this embodiment, this optical fiber type information includes coating heating condition information. The control unit 32 identifies the optical fiber type based on the optical fiber type information. For example, when the enter key 43E is operated in the state shown in FIG. 4, the control unit 32 specifies the type of optical fiber included in the connection program “NZ12 TYPE-P ITUTG655”. The fusion splicing device 3 selects a connection program including this optical fiber type and identifies it as a determined connection program.

  In step S1, when the selection of the connection program is confirmed (step S1; YES), the control unit 32 reads out the covering heating condition information included in the selected connection program from the storage unit 33 (step S2). The connection program stored in the storage unit 33 includes a plurality of items for fusing and connecting optical fibers.

  Specifically, as shown in FIG. 5, in addition to the connection program number and connection program name, each item includes a discharge heating current, a discharge heating time, and an optical fiber pushing amount when the optical fibers are fusion-bonded. It is. Among the connection programs, the values of each item of “Discharge heating current”, “Discharge heating time”, and “Optical fiber push-in amount” included in the connection program are values appropriate for the type of optical fiber corresponding to the connection program. It has become. Using the values of these items, the fusion splicing device 3 performs fusion splicing of optical fibers by a fusion splicing unit (not shown). Information such as “discharge heating current”, “discharge heating time”, and “optical fiber push-in amount” included in the connection program is optical fiber type information for specifying the type of optical fiber.

  Furthermore, the item of the connection program includes a coating heating condition when the coating removal device 2 heats and removes the coating of the optical fiber to be connected. The coating heating conditions include the heating temperature and heating time of the heater 14 in the coating removal apparatus 2. The control unit 32 reads out the coating heating condition included in the selected connection program from the storage unit 33. For example, the coating heating condition included in the selected connection program “NZ12 TYPE-P ITUTG655” is read from the storage unit 33 as information based on the optical fiber type information.

  Then, the control part 32 transmits the coating heating condition information according to the read coating heating condition via the communication part 34 (step S3). In the coating removal apparatus 2, when the coating heating condition setting process is started, a process of waiting for transmission of the coating heating condition information from the fusion splicing apparatus 3 is performed. When the covering heating condition information is transmitted, the communication unit 11 in the covering removing apparatus 2 receives the covering heating condition information from the fusion splicing apparatus 3 and outputs it to the control unit 12. The control unit 12 stores the coating heating condition information output from the communication unit 11 in the storage unit 13 as the set coating heating condition (step S4). At this time, when the set covering heating condition is already stored in the storage unit 13, the set covering heating condition is overwritten with the new set covering heating condition and the setting covering heating condition is changed. Thus, the covering heating condition setting process is completed.

  After the coating heating condition setting process is completed, when the coating removal of the optical fiber in the coating removal apparatus 2 is performed, the cover member 23 is closed and the heating of the optical fiber coating by the heater 14 is started. Heat treatment is performed. Hereinafter, the procedure of the covering heat treatment will be described with reference to FIG.

  As shown in FIG. 6, when the coating heating process of the coating removal apparatus 2 is started, the control unit 12 reads out the set coating heating conditions stored in the storage unit 13, and the heater 14 under the read set coating heating conditions. The coating is heated (step S11). In this manner, the heater 14 performs coating heating of the optical fiber using the set coating heating condition information. As shown in FIG. 7, the set coating heating condition information includes the coating heating temperature and the coating heating time (the set coating heating temperature and the set coating heating time). The control unit 12 performs the covering heating for t3 seconds at the read set covering heating condition, here, T3 ° C. Thus, the coating heating process is completed.

  Here, a temperature change of the heater 14 when the covering heating process is performed will be described. FIG. 8A shows the temperature change of the heater when the covering heating process is performed when the power saving operation is performed and the preheating of the heater 14 is stopped. As shown in FIG. 8A, when the power saving operation is performed, the heater 14 is kept at room temperature until the covering heating process is started. When the operator closes the lid member 23 at time t11 seconds, the control unit 12 controls the heater 14 to start the coating heating process.

  The heater 14 is heated by heating. Then, when time elapses and the temperature of the heater 14 reaches the set coating heating temperature at time t12 seconds, the control unit 12 starts constant temperature control of the heater 14 and maintains the temperature of the heater 14 at the set coating heating temperature. The controller 12 starts measuring the set coating heating time from time t12 seconds when the temperature of the heater 14 reaches the set coating heating temperature.

  Then, when the set coating heating time has elapsed and time t13 seconds have elapsed, the control unit 12 causes the buzzer sound output unit 16 to output a buzzer sound to notify the elapse of the set coating heating time. This time t13 seconds is the optimum timing for coating removal. At this timing, for example, the LED lamp may be controlled to light or blink. The worker who notices these notices moves the clamp portion 26 in a direction away from the base 21, and thereby the coating on the end portion of the heated and softened optical fiber is pulled out. In this way, the coating of the optical fiber is removed. It is assumed that the operator opens the lid member 23 in order to take out the optical fiber with the coating removed at time t14 seconds. When the opening of the lid member 23 is detected by, for example, a sensor (not shown), the control unit 12 ends the heating of the heater 14. When the control unit 12 finishes heating the heater 14, the covering heating process is finished. Thereafter, the temperature of the heater 14 gradually decreases to room temperature.

  Thus, the coating heating process under the set coating heating conditions is performed. In this embodiment, it is defined that the measurement of the coating heating time is started when the heater 14 reaches the set coating heating temperature (coating heating time = t13 seconds−t12 seconds). It may be defined as starting from the time when heating is started (coating heating time = t13 seconds−t11 seconds). The starting point of the set covering heating time may be the arrival time of the set covering heating temperature of the heater 14 or the heating start time of the heater 14.

  Next, a first modification of the covering heating condition setting process will be described. The coating heating condition setting process of the first modification mainly includes information stored in the storage unit 13 of the coating removal apparatus 2 and the storage unit 33 of the fusion splicing apparatus 3, respectively, and the control unit 12 and the fusion unit of the coating removal apparatus 2. The control of the control unit 32 of the destination connection device 3 is different from the above embodiment. Hereinafter, the first modification will be described focusing on differences from the above-described embodiment.

  In the first modification, the connection program number is transmitted from the fusion splicing device 3 to the coating removing device 2 as information based on the optical fiber type information. The connection program number is selected by selecting an operator's connection program in the fusion splicing device 3. The control unit 12 of the coating removal apparatus 2 specifies the coating heating condition using the transmitted connection program number. The storage unit 13 stores information on the specified coating heating condition as set coating heating condition information. The heater 14 reads the coating heating condition specified using the connection program number, and coats and heats the optical fiber under the read coating heating condition. Thus, the heater 14 performs coating heating of the optical fiber using the received connection program number. Hereinafter, the covering heating condition setting process in the first modification will be described.

  In the covering heating condition setting process in the first modified example, as shown in FIG. 9, the control unit 32 determines whether or not the selection of the connection program has been confirmed (step S21). This determination is performed in the same manner as in step S1 (see FIG. 3) of the above embodiment. As a result, when the selection of the connection program is not finalized (step S21; NO), the coating heating condition setting process is terminated as it is.

  When the selection of the connection program is confirmed (step S21; YES), the control unit 32 transmits the selected connection program number to the coating removal apparatus 2 via the communication unit 34 (step S21). S22). In the coating removal apparatus 2, when the coating heating condition setting process is started, a process of waiting for transmission of the connection program number from the fusion splicing apparatus 3 is performed. When the connection program number is transmitted, the control unit 12 in the coating removal apparatus 2 stores the connection program number transmitted from the fusion splicing apparatus 3 via the communication unit 11 in the storage unit 13. Then, the coating heating condition included in the coating heating program corresponding to the connection program number is stored as the set coating heating condition (step S23).

  The storage heating program shown in FIG. 10 is stored in the storage unit 13 of the coating removal apparatus 2 in the first modification. The coating heating program includes a coating heating temperature and a coating heating time corresponding to the connection program of the fusion splicing device 3. More specifically, the coating heating program includes the coating heating temperature and the coating heating time included in the connection program having the connection program number common to the coating heating program number. In addition, the connection program memorize | stored in the memory | storage part 33 of the fusion splicing apparatus 3 in a 1st modification may be the connection program shown in FIG. It may be a connection program excluding the coating heating time.

  The control unit 12 can read the coating heating condition from the transmitted connection program number. Specifically, when the connection program number 3 is transmitted, the connection program number 3 is referred to the coating heating program, and the coating heating temperature which is the coating heating condition included in the coating heating program 3 corresponding to the connection program number 3 Read T3 and coating heating time t3. The read coating heating temperature T3 and coating heating time t3 are stored in the storage unit 13 as set coating heating conditions. Thus, the covering heating condition setting process is completed.

  In the coating heating condition setting process in the first modified example, the connection program number is transmitted from the fusion splicing device 3 to the coating removing device 2. However, for example, the coating heating program number may be transmitted. . In this case, in the item of the connection program (see FIG. 5) in the above embodiment, instead of the items of “coating heating condition” and “coating heating time”, an item of connection program number is provided, and the connection program selected and confirmed The included heating program number may be transmitted to the coating removal apparatus 2.

  Subsequently, a second modification of the covering heating condition setting process will be described. The coating heating condition setting process of the second modified example is similar to the first modified example, and the information stored in the storage unit 13 of the coating removal device 2 and the storage unit 33 of the fusion splicing device 3 and the control of the coating removal device 2 respectively. Control of the control part 32 of the part 12 and the fusion splicing apparatus 3 is different from the above embodiment. Hereinafter, the second modification will be described focusing on the differences from the above embodiment.

  In the second modification, coating information is transmitted from the fusion splicing device 3 to the coating removing device 2 as information based on the optical fiber type information. The covering information is selected by selecting an operator's connection program in the fusion splicing device 3. The control unit 12 of the coating removal apparatus 2 specifies the coating heating condition using the transmitted coating information. The storage unit 13 stores information on the specified coating heating condition as set coating heating condition information. The heater 14 reads the coating heating condition specified using the connection program number, and coats and heats the optical fiber under the read coating heating condition. Thus, the heater 14 performs coating heating of the optical fiber using the received coating information. Hereinafter, the covering heating condition setting process in the second modification will be described.

  In the covering heating condition setting process in the second modification, as shown in FIG. 11, the control unit 32 determines whether or not the selection of the connection program has been confirmed (step S31). This determination is made in the same manner as in the above embodiment. As a result, when the selection of the connection program is not finalized (step S31; NO), the control unit 32 ends the coating heating condition setting process as it is.

  Further, when the selection of the connection program is confirmed (step S31; YES), the control unit 32 reads the cover information included in the selected connection program (step S32). In the second modification, the plurality of connection programs stored in the storage unit 33 include the same connection program number, connection program name, and discharge when connecting optical fibers as shown in FIG. In addition to items such as heating current, discharge heating time, and optical fiber indentation amount, each item includes coating information such as the number of optical fiber cores, coating diameter, and coating material. The control unit 32 reads from the storage unit 33 the number of optical fiber cores, the coating diameter, and the coating material, which are the coating information corresponding to the determined connection program.

  Subsequently, the control unit 32 transmits the read coating information to the coating removal apparatus 2 via the communication unit 34 (step S33). In the coating removal apparatus 2, when the coating heating condition setting process is started, a process of waiting for transmission of coating information from the fusion splicing apparatus 3 is performed. When the coating information is transmitted, the control unit 12 in the coating removal apparatus 2 refers to the coating heating program stored in the storage unit 13 with respect to the coating information transmitted from the fusion splicing device 3 via the communication unit 11. Then, the coating heating condition included in the coating heating program including the transmitted coating information is stored as the set coating heating condition (step S34).

  The coating heating program shown in FIG. 13 is stored in the storage unit 13 of the coating removal apparatus 2 in the second modification. The covering heating program includes covering information included in a connection program having a connection program number in common with the covering heating program number among the connection programs stored in the storage unit 33 of the fusion splicing device 3. Specifically, the connection program with the connection program number 1 shown in FIG. 12 includes the core number Na, the coating diameter Ra, and the coating material OO as the coating information. Further, the coating heating program of the coating heating program number 1 shown in FIG. 13 includes the core number Na, the coating diameter Ra, and the coating material OO as the coating information.

  The control unit 12 can identify the coating heating program from the transmitted coating information, and can read the coating heating conditions included in the identified coating heating program. Specifically, when the coating information stored in the connection program of the connection program number 3 is transmitted, the control unit 12 identifies the coating heating program number 3 with reference to the transmitted coating information in the coating heating program. Then, the coating heating temperature T3 and the coating heating time t3 which are coating heating conditions included in the coating heating program of the coating heating program number 3 are read out. Then, the control unit 12 stores the read coating heating temperature T3 and coating heating time t3 in the storage unit 13 as set coating heating conditions. Thus, the covering heating condition setting process is completed.

  In addition to the coating heating condition setting process, the optical fiber coating removal system 1 performs various processes such as a power saving process, a maintenance information acquisition / display process, a buzzer volume setting process, and a buzzer sound output process. Hereinafter, each of these processes will be described.

  The power saving process is performed according to the flowchart shown in FIG. When the fusion splicing device 3 starts the power saving process, the control unit 32 determines whether or not the power saving operation is performed (step S41). Whether or not the power saving operation is performed is determined by whether or not the power source is switched from the commercial AC power source to the built-in battery. As a result, when the power saving operation is not performed (step S41; NO), since it is a normal state, the control unit 32 ends the power saving start process as it is.

  When the power saving operation is performed (step S41; YES), the control unit 32 transmits the power saving information to the coating removal apparatus 2 via the communication unit 34 (step S42). In the coating removal apparatus 2, when the power saving process is started, a process of waiting for transmission of the power saving information from the fusion splicing apparatus 3 is performed. When the power saving information is transmitted, the control unit 12 in the coating removal device 2 receives the power saving information transmitted from the fusion splicing device 3 via the communication unit 11 (step S43), Stop of preheating of the heater 14 is set (step S44). Thus, the heater 14 controls the preheating of the heater 14 using the power saving information. Thus, the power saving process is completed.

  The setting of the power saving information in the power operation can be performed by displaying the power saving setting screen shown in FIG. 15 displayed on the display monitor 42 of the fusion splicing device 3. The power saving setting screen shown in FIG. 15 can be displayed when the operator operates the input key 43 in the fusion splicing device 3. Further, by operating the input key 43 in the fusion splicing device 3, the power saving setting screen shown in FIG. 15 can be displayed. As shown in FIG. 15, the power saving setting screen includes an ID number (Ribbon Stripper ID) of the coating removal apparatus 2 as identification information, a power saving mode (Power Saving Mode) as power saving information, and a preheating temperature (Preheat). Temp) and shutdown time information is displayed.

  Among these, the power saving mode is a power saving state (Power Saving) in which a power saving operation is performed when ON, and a normal state (Preheat) in which the heater 14 is preheated when OFF. It is. The preheating temperature is a temperature at which the heater 14 is preheated during a normal state where the power saving operation is not performed. The shutdown time is the time from when the power saving operation is started until the preheating is stopped when no operation is continued.

  In the example shown in FIG. 15, the power saving mode is a normal state in which the power saving operation is not performed, the preheating temperature is set to 80 ° C., and the shutdown time of the fusion splicing device 3 is set to 10 minutes. . When the power saving setting screen is displayed, by operating the input key 43, a power saving operation setting instruction is given to the coating removal apparatus 2 for setting the power saving mode, the preheating temperature, and the shutdown time as the power saving information. be able to. Note that the ID number of the coating removal apparatus 2 as identification information is the information transmitted from the coating removal apparatus 2 to the fusion splicing apparatus 3 in the maintenance information acquisition and display process described later.

  When the fusion splicing device 3 finishes the power saving operation and enters a normal state, the control unit 32 of the fusion splicing device 3 transmits normal information to the control unit 12 of the coating removal device 2. The control unit 12 of the coating removal apparatus 2 that has received the normal information ends the power saving operation, shifts to a normal state, and starts preheating the heater 14 when the preheating of the heater 14 is stopped.

  A temperature change of the heater 14 in the normal state will be described. FIG. 8B shows the temperature change of the heater when the covering heating process is performed when the heater 14 is preheated in the normal state. As shown in FIG. 8B, in the normal state, the control unit 12 performs constant temperature control for maintaining the heater 14 at the preheating temperature. When the operator closes the lid member 23 at time t21 seconds, the control unit 12 controls the heater 14 to start the coating heating process.

  The heater 14 is heated by heating. Then, when time elapses and the temperature of the heater 14 reaches the set coating heating temperature at time t22 seconds, the control unit 12 starts constant temperature control of the heater 14 and maintains the temperature of the heater 14 at the set coating heating temperature. In the normal state where the power saving operation is not performed, since the heater 14 is preheated, the time for the heater 14 to reach the set coating heating temperature is shorter than when the power saving operation is performed. . The controller 12 starts measuring the set coating heating time from time t22 seconds when the temperature of the heater 14 reaches the set coating heating temperature.

  Then, when the set coating heating time elapses and the time t23 seconds, the optimal timing for coating removal is reached. At this time, the control unit 12 may control the LED lamp to light or blink. The worker who notices these notices moves the clamp portion 26 in a direction away from the base 21, and thereby the coating on the end portion of the heated and softened optical fiber is pulled out. In this way, the coating of the optical fiber is removed. When the operator opens the cover member 23 to take out the optical fiber with the coating removed at time t24 seconds, the control unit 12 ends the heating of the heater 14. When the control unit 12 finishes heating the heater 14, the covering heating process is finished. Thereafter, the temperature of the heater 14 gradually decreases to the preheating temperature. When the temperature reaches the preheating temperature at time t25 seconds, the control unit 12 starts constant temperature control and maintains the heater 14 at the preheating temperature. Thus, the coating heating process is performed at the coating heating temperature and the coating heating time under the set coating heating conditions. Note that the heating time may be defined as a heating time that is a certain time after the heating of the heater 14 is started as in the power saving mode (heating time = t23−t21).

  The maintenance information acquisition / display process is performed according to the flowchart shown in FIG. As the maintenance information acquisition display process, the coating removal apparatus 2 performs a maintenance information acquisition process, and the fusion splicing apparatus 3 performs a maintenance information display process. As illustrated in FIG. 16, when the coating removal apparatus 2 starts the maintenance information acquisition process, the control unit 12 of the coating removal apparatus 2 acquires maintenance information of the coating removal apparatus 2 in the maintenance information acquisition unit 15 (step S51). ). The maintenance information includes the number of times the sheath removing blade 24 is used, the remaining amount of the built-in battery built in the sheath removing device 2 and the number of charge / discharge cycles, and the occurrence of an abnormality in the sheath removing device 2.

  The maintenance information acquisition unit 15 includes a battery charge amount sensor, a battery charge / discharge number counter, a cover removal number counter, an abnormality detection sensor, and the like. The battery charge amount sensor detects and acquires the remaining charge of the built-in battery in the coating removal device 2. The battery charge / discharge number counter counts the number of charge / discharge times of the built-in battery in the coating removal apparatus 2. The charging / discharging frequency of the built-in battery in the coating removal apparatus 2 is counted separately for the charging frequency and the discharging frequency. However, the number of times of charging / discharging may be counted together. Here, the number of times the internal battery is charged is counted. The coating removal number counter counts the number of times the coating removal blade 24 is put into the coating of the optical fiber, in other words, the number of times the coating removal blade 24 is used. The abnormality detection sensor detects an abnormality that has occurred in the coating removal device 2, such as overheating of the built-in battery or the heater 14, contamination of foreign matter (remaining coating waste after extraction), poor closure of the lid member 23, etc. These abnormalities are detected. The maintenance information acquisition unit 15 is configured to control the detected remaining charge amount and abnormality of the built-in battery, and the counted number of charge / discharge of the built-in battery and the number of times of use of the coating removal blade 24 as information based on the acquired maintenance information. 12 is output.

  The control unit 12 transmits information based on the maintenance information acquired by the maintenance information acquisition unit 15 to the fusion splicing device 3 via the communication unit 11 (step S52). At this time, the control part 12 transmits together the information based on the identification information of the coating removal apparatus 2 (step S52). The control unit 12 repeatedly performs the maintenance information acquisition start process every predetermined time, for example, every 5 minutes, from when the coating removing apparatus 2 and the fusion splicing apparatus 3 are connected. Further, the information based on the identification information of the coating removal device 2 may be transmitted to the fusion splicing device 3 only once when the coating removal device 2 and the fusion splicing device 3 are connected.

  In the fusion splicing device 3, when the maintenance information display processing is started, processing for waiting for transmission of information based on the maintenance information from the coating removal device 2 and information based on the identification information is performed. When the information based on the maintenance information and the information based on the identification information are transmitted, the control unit 32 in the fusion splicing device 3 uses the information and the identification information based on the maintenance information transmitted from the coating removal device 2 via the communication unit 34. (Step S53), and using the information based on the received maintenance information and the information based on the identification information, the maintenance information and the identification information are displayed on the display monitor 42 (step S54). As described above, the control unit 32 outputs the maintenance information and the identification information to the display monitor 42 using the information based on the received maintenance information and the information based on the identification information. Thus, the maintenance information acquisition / display process ends.

  Note that a battery charge / discharge number counter or a cover removal counter may be provided in the control unit 12, and a battery charge / discharge sensor or a cover removal sensor may be provided in the maintenance information acquisition unit 15. In this case, the maintenance information acquisition unit 15 detects charging / discharging of the built-in battery by the battery charging sensor, detects coating removal of the optical fiber by the coating removal sensor, and charging / discharging information and coating removal information based on these detection results. May be output to the control unit 12, and the charge / discharge number of the built-in battery and the usage number of the coating removal blade 24 may be counted by the battery charge / discharge number counter or the coating removal counter of the control unit 12. Alternatively, a battery charge / discharge number counter and a cover removal counter are provided in the control unit 32 of the fusion splicing device 3, and the number of times the built-in battery is charged and discharged and the number of times the cover removal blade 24 is used are counted by the battery charge / discharge number counter and the cover removal counter. You may make it do. In this case, the maintenance information acquisition unit 15 determines the number of times of charging / discharging of the built-in battery detected by the battery charge / discharge sensor and the coating removal sensor and the number of times of use of the coating removal blade 24 of the fusion splicing device 3 via the control unit 12 or the like. What is necessary is just to transmit to the control part 32.

  The operator can view the maintenance information by displaying the maintenance information display screen shown in FIG. 17 on the display monitor 42 of the fusion splicing device 3. The maintenance information display screen shown in FIG. 17 is displayed, for example, when the operator operates the input key 43 in the fusion splicer 3. Various information included in the identification information and the maintenance information is displayed on the maintenance information display screen. Among these, the ID number (Ribbon Stripper ID) of the sheath removing device 2 is displayed as the identification information, and the remaining charge (Battery Capacity) and the number of times of charging (Battery Recharged) of the built-in battery in the sheath removing device 2 are the maintenance information. In addition, the number of times of use of the coating removal blade 24 (Blade Stripped) is displayed. In the maintenance information display screen shown in FIG. 17, the remaining charge of the built-in battery in the sheath removing device 2 is displayed as 50%, the number of times of charging is 110 times, and the number of times of use of the sheath removing blade 24 is 11052 times.

  The buzzer volume setting process is performed according to the flowchart shown in FIG. As shown in FIG. 18, in the buzzer sound volume setting process, the control unit 32 of the fusion splicing device 3 determines whether or not the buzzer sound volume has been determined (step S61). As a result, if the buzzer volume has not been determined (step S61; NO), the buzzer volume setting process is terminated as it is.

  The operator can display the buzzer information setting screen shown in FIG. 19 on the display monitor 42 of the fusion splicing device 3 and set the buzzer volume of the coating removal device 2. The buzzer information setting screen shown in FIG. 19 is displayed, for example, when the operator operates the input key 43 in the fusion splicing device 3. On the buzzer information setting screen, the ID number (Ribbon Stripper ID), buzzer volume, and buzzer sound generation condition candidate of the coating removal device 2 are displayed as identification information. Buzzer sound generation condition candidates include “Heat Completed”, “Power On (Power On)”, “Power Off (Power Off)”, “Shut Down”, “Rechage Start”, “Charge End” (Rechage End) ”is specified. When the operator operates the input key 43 of the fusion splicing device 3, the buzzer sound volume can be set as a buzzer sound volume setting instruction, and the buzzer sound generation condition can be selected from the buzzer sound generation condition candidates. In the buzzer information setting screen shown in FIG. 19, the buzzer volume is displayed as “4”, and “heating completed”, “power on”, and “end of charging” are selected and displayed as buzzer sound generation conditions. In this embodiment, the buzzer volume is set to five levels “1” to “5”, and the volume increases as the number increases. However, the buzzer volume may be more or less than five steps. Further, the buzzer volume may be an analog type instead of a digital type in which stages are divided by integers.

  When the buzzer volume is fixed (step S61; YES), the control unit 32 transmits the buzzer volume information to the coating removal device 2 via the communication unit 34 (step S62). The control unit 12 in the sheath removal apparatus 2 receives the buzzer volume information transmitted from the fusion splicing apparatus 3 via the communication unit 11, and stores it in the storage unit 13 as the set buzzer volume information (step S63). Thus, the buzzer volume setting process is terminated.
