Various types of piping are used in air conditioners and refrigerators. Various joining techniques are used for joints of these pipes (see Patent Documents 1 and 2, for example).

Japanese Patent No. 5328724 Japanese Patent No. 3194054

Conventionally, condensers, evaporators, and compressors used in air conditioners and refrigeration systems were mainly connected by copper pipes, which are excellent in workability. However, in recent years, attention has been focused on aluminum, which is cheaper and lighter than copper, as a material to replace copper. However, since aluminum is more fragile than copper, it is not easy to connect pipes by flaring, which is easy for pipes made of copper. Therefore, brazing the pipes together is conceivable as a method for connecting aluminum pipes. In the case of brazing, it is possible to connect pipes by melting aluminum with additives into the gaps between pipes as brazing material, so it is possible to connect pipes more reliably than connecting pipes by flaring. can.

However, since the connection of pipes used for air conditioners and refrigeration equipment is performed at the construction site, it is necessary to arrange a worker skilled in brazing at the construction site. However, in recent years, the decrease in the working population has become a social problem, and it is difficult to secure skilled workers. Therefore, it is required to appropriately perform the brazing work, which requires adjustment depending on the atmospheric temperature at the joint of the pipes, the diameter of the pipes, and various other factors, regardless of the skill level of the operator.

Therefore, an object of the present application is to provide a technique that enables even an unskilled operator to appropriately braze piping.

In order to solve the above problems, in the present invention, the brazing work is voice-guided to the worker, and the timing of the voice guidance is adjusted according to the temperature of the work site where the brazing is performed.

More specifically, the present invention is a voice guidance device, which includes a reproduction processing unit that reproduces voice data of a brazing method that provides voice guidance to a worker, and an environment that acquires thermal information of a work site where brazing is performed. and an information acquisition unit, wherein the reproduction processing unit adjusts the reproduction timing of the audio data to be reproduced based on the thermal information acquired by the environment information acquisition unit.

With the above-mentioned voice guidance device, since the voice data of the brazing method is reproduced, even if the worker is not skilled in the brazing work, the worker can perform the work according to the voice guidance reproduced by the above-mentioned voice guidance device. If done, the brazing work can be done.

In the voice guidance device described above, since the timing of voice guidance is adjusted according to thermal information such as the temperature of the work site where brazing is performed, voice guidance is not provided at inappropriate timing. Therefore, if the worker follows the voice guidance reproduced by the above-mentioned voice guidance device, the worker can perform the brazing at the temperature suitable for the work site. Therefore, by using the voice guidance device, even an unskilled worker can properly braze the pipes.

In addition, the reproduction processing unit controls the sound reproduced by the reproduction processing unit based on the information in the table that defines the relationship between the temperature of the work site and the timing of reproducing the audio data, and the thermal information acquired by the environment information acquisition unit. It may be one that adjusts the timing of data reproduction.

With such a table, the relationship between the temperature of the work site and the timing of reproducing the audio data can be freely defined, compared to the case where the amount of timing adjustment is calculated by arithmetic processing each time the audio data is reproduced. Also, it is possible to reduce the load of reproduction processing when performing voice guidance.

Further, the apparatus further includes a pipe information acquisition unit that acquires information on the pipe to be brazed, and the regeneration processing unit combines the thermal information acquired by the environment information acquisition unit with the information on the pipe acquired by the pipe information acquisition unit. Based on this, the reproduction timing of the audio data reproduced by the reproduction processing unit may be adjusted. Here, the information about the piping includes, for example, the diameter of the piping, the thickness of the piping, the material of the piping, the length of the piping, and the like.

If the reproduction timing of the audio data reproduced by the reproduction processing unit is adjusted in this way, it is possible to provide not only thermal information such as the temperature of the work site, but also the audio guidance of the brazing work procedure at a timing suitable for the piping. becomes possible.

In this case, the reproduction processing unit may reproduce audio data of information on the length of the brazing material consumed in brazing based on the information on the pipe acquired by the pipe information acquisition unit. The brazing material information acquisition unit acquires information on the brazing material used for brazing, and the reproduction processing unit reproduces the audio data to be reproduced based on the information on the brazing material acquired by the brazing material information acquisition unit. You may make it adjust a timing. With such a voice guidance device, the brazing material can be easily handled during brazing.

Also, the reproduction processing unit may output the reproduced audio signal to a bone conduction speaker worn by the worker.

If the bone conduction speaker is used, even if there is noise at the work site of brazing, the worker can easily hear the voice guidance of the voice guidance device. Therefore, it is possible to minimize defects in the brazing work caused by the worker failing to hear the voice guidance reproduced at appropriate timing. In addition, by adopting a type that does not directly block the ears like earphones, it does not prevent the worker from grasping the surrounding situation by the sound, so safety can be ensured.

Moreover, the present invention can also be viewed from the aspect of a method or program. The present invention is, for example, a voice guidance method, and includes a reproduction processing step of reproducing voice data of a brazing method for giving voice guidance to a worker, and an environment information acquisition step of acquiring thermal information of a work site where brazing is performed. and , wherein in the reproduction processing step, timing of reproduction of the audio data to be reproduced may be adjusted based on the thermal information acquired in the environment information acquisition step.

By the way, the above problems can also be solved by the following inventions.

That is, the present invention is a guidance device, comprising: an information output unit that outputs information on a brazing method to be guided to a worker; an environment information acquisition unit that acquires thermal information on a work site where brazing is performed; and the information output unit may adjust the timing of outputting the brazing method information based on the thermal information acquired by the environment information acquisition unit. Further, the present invention may be a method or program aspect of the invention of the guide device.

In addition, the present invention is a guide device, comprising an information output unit that outputs information on a brazing method to be guided to a worker, and a pipe information acquisition unit that acquires information on a pipe to be brazed, The information output unit may adjust the timing of outputting the brazing method information based on the pipe information acquired by the pipe information acquisition unit. Further, the present invention may be a method or program aspect of the invention of the guide device.

In this case, the information output unit may further output information on the length of the brazing material consumed in brazing based on the information on the pipe acquired by the pipe information acquisition unit. The brazing material information acquisition unit acquires information on the brazing material used for brazing, and the information output unit outputs brazing method information based on the information on the brazing material acquired by the brazing information acquisition unit. You may adjust the timing which carries out.

With the voice guidance device, guidance device, method, and program described above, even workers unskilled in brazing can appropriately braze pipes.

Embodiments of the present invention will be described below. The embodiments shown below illustrate embodiments of the present invention, and do not limit the technical scope of the present invention to the following forms.

FIG. 1 is a diagram showing the hardware configuration of a voice guidance device according to an embodiment. The voice guidance device 1 is a computer terminal equipped with a CPU (Central Processing Unit), a memory, an input/output interface, and the like. Various inputs and outputs are realized through the input/output interface. The voice guidance device 1 executes, for example, a voice guidance program stored in a memory by means of a CPU, so that various functional units such as a temperature information acquisition unit 2, a pipe information acquisition unit 3, a reproduction processing unit 4, and an audio output unit 5 is realized in the voice guidance device 1.

The temperature information acquisition unit 2 is a functional unit that acquires thermal information on a work site where brazing is performed. Work site thermal information is a type of physical quantity information related to elements that can change the timing of executing various procedures in brazing work. ambient humidity, the temperature of the pipe to be brazed, the temperature of the brazing material, and the like.

The temperature information acquisition unit 2 may acquire thermal information on the work site from a temperature sensor 6 externally connected to the voice guidance device 1, or operate a touch panel or the like provided in the voice guidance device 1. It may be obtained from the operator through an input interface. If the temperature sensor 6 is installed in the space of the work site where the brazing is performed, the temperature information acquisition unit 2 can acquire the ambient temperature of the work site where the brazing is performed. In addition, when the worker inputs the measured value of the thermometer installed in the space of the work site where the brazing is performed through the input interface, the temperature information acquisition unit 2 obtains the ambient temperature of the work site where the brazing is performed. can be obtained.

The pipe information acquisition unit 3 is a functional unit that acquires information about pipes that are objects to be brazed. Information about piping is a type of physical quantity information about elements that can change the timing of executing each procedure in brazing work, like thermal information.

The pipe information acquisition unit 3 acquires information about the diameter, thickness, material, and length of a pipe to be brazed from an operator who operates a touch panel or the like provided in the voice guidance device 1 through an input interface. Alternatively, it may be acquired by analyzing an image of the pipe taken by a camera, which is an imaging means provided in the voice guidance device 1 .

The reproduction processing unit 4 is a functional unit that reproduces audio data of a brazing method for providing audio guidance to the worker. The reproduction processing unit 4 reads out the brazing method audio data developed in the memory of the audio guidance device 1 at an appropriate timing, and the audio output unit 5 reproduces the audio data so as to be in a data format that allows audio output. Further, the reproduction processing unit 4 adjusts the reproduction timing of the reproduced audio data based on the information obtained by the temperature information obtaining unit 2 and the pipe information obtaining unit 3 when reproducing the audio data. Details of the adjustment will be described later.

The audio output unit 5 is a functional unit that outputs the audio data reproduced by the reproduction processing unit 4 in a form that can be audibly sensed by the operator. As shown in FIG. 1, for example, when the operator wears wireless bone conduction headphones 7, the audio output unit 5 outputs the audio data reproduced by the reproduction processing unit 4 to the audio guidance device 1. The information is wirelessly transmitted to the bone conduction headphones 7 through the short-range wireless communication device. When the operator wears wired headphones, the audio output unit 5 transmits the audio data reproduced by the reproduction processing unit 4 to the headphones through an audio amplifier provided in the audio guidance device 1 by wire. .

In the voice guidance device 1, the CPU executes the computer programs stored in the memory, thereby realizing various functional units as described above. Then, in the voice guidance device 1, the following processing flow is realized.

FIG. 2 is a diagram showing an example of a processing flow realized by the voice guidance device 1. As shown in FIG. In the voice guidance device 1, the processing flow shown in FIG. 2 is realized by the cooperation of the various functional units as described above. That is, when the CPU of the voice guidance device 1 executes the computer program and implements various functional units, in the voice guidance device 1, the pipe information acquisition unit 3 causes the worker to input information about the pipe to be brazed. (S101). Then, when the information on the piping to be brazed is input, the temperature information acquiring section 2 of the voice guidance device 1 acquires the thermal information of the work site (S102). Then, when the operator performs an operation to start voice guidance, in the voice guidance device 1, the reproduction processing unit 4 starts voice guidance of various procedures performed in the brazing work (S103).

FIG. 3 is a diagram exemplifying a pipe diameter input screen displayed on the voice guidance device 1. As shown in FIG. In step S101, for example, through an input screen as illustrated in FIG. 3, input of the pipe diameter of the pipe to be brazed is requested. For example, as shown in FIG. 3A, if an input screen is provided with an input field for inputting a numerical value of the pipe diameter, the operator using the voice guidance device 1 can input the numerical value of the pipe diameter. Enter in the input field. Further, for example, as shown in FIG. 3B, if the input screen has buttons for selecting the pipe diameter, the operator using the voice guidance device 1 selects the button for the corresponding pipe diameter. do. Further, for example, as shown in FIG. 3C, if the input screen includes the image of the camera, the user who uses the voice guidance device 1 can move the camera so that the piping is reflected in the image of the camera. Adjust position. When a pipe appears in the image of the camera on the screen of FIG. The diameter of the pipe is calculated based on the distance. Note that if the pipe diameter input in step S101 is a pipe diameter that is not planned to be used at the site of the brazing work, the pipe diameter information acquisition unit 3 may warn to that effect. Such warnings can prevent the use of incorrect piping. Although the pipe diameter input screen has been exemplified here, the information requested to be input in step S101 may be not only the pipe diameter of the pipe, but also the thickness of the pipe, the material of the pipe, and the length of the pipe.

FIG. 4 is a diagram showing an example of a table used for determining the timing of reproducing audio data. In the table that the reproduction processing unit 4 refers to when determining the timing of reproducing the audio data, for example, as shown in FIG. stipulated in

The timing for reproducing audio data is defined according to the following conditions. For example, the heating time required from the start of heating by a burner until reaching a predetermined temperature generally increases as the ambient temperature of the work site where the brazing operation is performed decreases. In addition, the heating time required from the start of heating by the burner until reaching a predetermined temperature increases as the pipe diameter of the pipe to be heated increases. Therefore, in the table that the reproduction processing unit 4 refers to when determining the timing of reproducing the audio data, the time from when the voice guidance for the start of heating until when the voice guidance for stopping the heating is given indicates that the brazing work is performed. The timing for reproducing audio data is defined so that it becomes longer as the ambient temperature of the site decreases. In addition, in the table, the timing of reproducing the voice data is defined such that the time from when the voice guidance for starting heating is given until when the voice guidance for stopping heating is given increases as the pipe diameter of the pipe to be heated increases. ing. In addition, in the table, not only the time from the voice guidance for the start of heating to the voice guidance for the stop of heating, but also the timing of the voice guidance for changes in the color of the flame of the burner and the color of the brazing filler metal, for example, The timing of the voice guidance for various procedures, such as the timing of the voice guidance of the wetness and spreading, and the timing of how to move the burner, depends on the ambient temperature of the work site where the brazing work is performed and the pipe diameter of the pipe to be heated. The timing of the reproduction of the audio data is defined so as to be performed at an appropriate timing. The same applies to the thickness, material, and length of piping. The heating time required from the start of heating by the burner to reaching a predetermined temperature varies depending on, for example, the thickness of the pipe, the material of the pipe, and the length of the pipe.

FIG. 5 is a diagram showing an example of the correspondence relationship between various procedures performed in the brazing work and the content of voice guidance provided by the voice guidance device 1. As shown in FIG. In the brazing operation, the brazing material is melted into the gaps between the members to be brazed while the members to be brazed are aligned with each other. The brazing material is selected to have a melting point close to that of the member to be brazed so that it can be easily integrated with the member to be brazed. Then, in the brazing operation, the brazing material is heated by a burner to its melting point so that the brazing material melts into the gap between the members to be brazed. In addition, the member to be brazed is also heated by a burner to near the melting point so that the heated and melted brazing material melts with the member to be brazed to facilitate integration. Therefore, if the heating time is too short, the brazing material will not melt, and if the heating time is too long, the member itself to be brazed will melt and become unusable.

Therefore, in the voice guide device 1 for guiding the work procedure to the worker who performs the brazing work, appropriate required tasks such as heating the brazing material with a burner are performed on the table so that each procedure is performed at appropriate timing. The time is defined for each of the temperature of the space in the work site where the brazing work is performed, the pipe diameter, thickness, material, and length of the pipe. Therefore, for example, if the pipe diameter input in step S101 is 6.35φ and the temperature of the work site space acquired in step S102 is 25° C., the regeneration processing unit 4 By referring to the table of 4, information on the appropriate time required for heating the brazing material (for example, 20 seconds when melting the brazing material) is acquired, and the voice is adjusted to the timing according to the required time. The data will be played. Further, if the ambient temperature of the work site space rises due to the brazing work, the required time corresponding to the raised temperature is referred to in the table. Note that gap guidance, such as counting the remaining seconds, may be performed between voice guidances. Specifically, you can count down to 20, 19, 18, etc. between "heat the pipe until the flame turns orange" and "melt the brazing material". The length of the gap guide is varied according to conditions such as pipe diameter and temperature. This gap guidance is preferable because it indicates how much work should be done.

FIG. 6 is a diagram showing a comparison of timings of reproduction of audio data. As can be seen by comparing "at normal temperature" and "at low temperature" shown in FIG. , and until the end of heating is announced. Also, as can be seen by comparing "At normal temperature" and "At high temperature" shown in FIG. The time from guidance to completion of heating is shortened.

In brazing, the melting point of the material to be brazed and the melting point of the brazing material are relatively close. requested. However, in the voice guidance device 1 of the above-described embodiment, the voice guidance of each procedure in the brazing work is performed at a timing according to the ambient temperature of the work site where the brazing is performed. A worker in use can perform work equivalent to that of a relatively highly skilled worker by performing work in accordance with the timing of the voice guidance.

For example, when it is desired to connect condensers, evaporators, compressors, and the like used in air conditioners and refrigeration systems, workers connect the pipes at the site where these devices are installed. Therefore, when the piping used in these devices is made of aluminum, which is cheaper and lighter than copper, and you want to connect the aluminum piping by brazing, the operator who performs the piping connection work should: The brazing work, which is more difficult than fastening with screws at the ends of flared pipes and welding work, is performed at construction sites where workability is inferior to factories. Therefore, it is extremely difficult for a worker who is not sufficiently skilled in brazing work to braze aluminum pipes at such a construction site. In recent years, it has become difficult to secure skilled workers due to a decrease in the working population. Therefore, it is difficult to allocate two workers, a skilled worker and an apprentice worker, to such a construction site. However, by using the voice guidance device 1 of the above-described embodiment, the worker can perform work equivalent to that of a skilled worker.

In the above-described embodiment, the series of processes from step S101 to step S103 are implemented by the voice guidance device 1 used at the construction site. Any one or more steps of the processing of may be implemented, for example, in one or more computers connected to a communication network. For example, the input of information on piping in step S101 may be performed to a computer on a communication network. Further, for example, the reproduction of the voice data in step S103 may be executed by a computer on the communication network, and the data of the voice signal may be sent to the voice guidance device 1. FIG. In such a form, for example, information on the evaluation result of the brazing state of the part where the brazing work was performed is provided from a plurality of voice guidance devices 1 connected on the communication network, and the information is received. Based on this, it is also possible to update the table used to determine the timing of reproducing the audio data.

When updating the table, for example, after the process of step S103 is completed, the operator is requested to input whether the brazing state is good or bad through the screen of the voice guidance device 1. FIG. Then, for example, if the input content is insufficient for wetting and spreading of the brazing filler metal, a predetermined amount is added to the numerical value of the heating time specified in the table. Also, for example, if the input content is damage due to dissolution of a pipe, a predetermined amount is subtracted from the numerical value of the heating time specified in the table. If the time for each procedure defined in the table is updated so as to increase or decrease according to the input of the quality of the brazing state, the voice guidance device 1 provides voice guidance at an appropriate timing according to the worker's characteristics. It is possible to do

Such updating of the table may be realized by the voice guidance device 1 alone, or may be performed by a server or the like on the communication network. When the voice guidance shown in the above embodiment is realized not only by the device installed at the work site but also by cooperation with a server on the communication network, for example, the following processing can be realized. FIG. 7 is a diagram showing an example of a voice guidance system implemented using a communication network. In the voice guidance system shown in FIG. 7, voice guidance device 1 is connected to server 9 via communication network 8 . The server 9 has a database that stores information for each work site, such as the computer that provides weather data, the temperature at the work site sent from the computer of the company that manages the materials at the work site, and the piping used at the work site. 10 are provided. In such a voice guidance system, for example, in step S101, instead of the temperature, information about the work site (for example, the name of the area of the work site, the name of the building, etc.) is input to the voice guidance device 1, and the voice guidance device 1 Based on the notified input information, the server 9 can specify the temperature and pipes to be used at the work site. When the temperature and pipes to be used at the work site are specified by the server 9, the voice guidance device 1 notifies the worker of the types of pipes that can be used at the work site based on the information provided by the server 9. , it is possible to provide voice guidance for brazing at a timing corresponding to the temperature of the work site. 4 is stored in the database 10 in place of the voice guidance device 1, for example, the authority to use the voice guidance device 1 can be assigned to the server 9. It is also possible to prevent unauthorized use of the voice guidance device 1 by a worker who is not permitted to use by the manager of the voice guidance system by checking on the side.

Also, the adjustment of the timing of reproducing the audio data may be performed by a method other than the above-described method using the table. In other words, the adjustment of the timing of the reproduction of the audio data is performed, for example, by correcting the specified standard time according to the ambient temperature of the work site where the brazing work is performed and the size of the pipe diameter. The timing may be adjusted according to the time set. For example, when the prescribed standard brazing material heating time is specified under the condition that the ambient temperature of the work site space is 20° C., the actual work site space measured by the temperature sensor 6 If the ambient temperature is 15° C., the heating time corresponding to the heat quantity lacking due to the temperature difference of −5° C. is calculated by an appropriate calculation formula, and the reproduction timing when the audio data is reproduced in step S103 is determined by the calculation formula. is adjusted to the heating time of the correction value calculated in .

Even if the timing of reproducing the voice data is thus realized by a method other than the table, the worker using the voice guidance device 1 performs each procedure of the brazing work according to the voice guidance given at appropriate timing. Therefore, it is possible to appropriately perform the brazing work of the piping.

By the way, the above embodiment can also be modified as follows.

FIG. 8 is a diagram showing a modification of the brazing material. In this modified example, the following brazing material 11 shown in FIG. 8 is used. The brazing filler metal 11 includes a rod 11a (an example of the "linear portion" referred to in the present application) which is a rod-shaped body of an alloy in which several kinds of metals are mixed with aluminum as a base material constituting the brazing filler metal, and a surface of the rod 11a. and a scale 11b provided along the longitudinal direction. The scale 11b is a scale that serves as a guideline for the amount of consumption of the rod 11a, and is arranged at regular intervals of 10 mm along the longitudinal direction. When the remaining amount of the brazing filler metal 11 becomes short, it is generally used up by being welded to other brazing filler metals 11 without waste. It is

The rod 11a is not limited to a linear rod-like body, and may be a slightly curved rod-like body. Moreover, the rod 11a is not limited to a round rod, and may be, for example, a square rod having a polygonal cross section. Moreover, the rod 11a may be cut from a long wire wound around a drum instead of being produced in the shape of a straight rod. Further, the rod 11a is not limited to one whose core portion is made of an alloy that constitutes a brazing material, and may be, for example, one in which flux is contained in a hollow portion of an alloy.

Moreover, the scale 11b is not limited to the form in which the scale 11b is uniformly provided over the entire length from one end to the other end in the longitudinal direction of the bar 11a. good too. Moreover, the scale 11b is preferably formed of a material that does not adversely affect the brazed portion. As the scale 11b formed of a substance that does not adversely affect the brazing portion, for example, flux, ink vaporized by heat during brazing, grooves engraved on the alloy forming the rod 11a, and the rod 11a are formed. Protrusions mounted on the alloy, and various others.

The brazing filler metal 11 is, for example, packaged by an appropriate number (for example, 100). The brazing material 11 is hermetically packaged in, for example, a bag or a resin case. Non-resealable packaging materials such as shrink films can be used for hermetic packaging. is preferred. The brazing material 11 is packaged in a bag or case containing a desiccant in order to prevent deterioration due to moisture. The desiccant is preferably fixed in the bag or the case by fixing means such as an adhesive material or a stopper.

Such a brazing material 11 is preferably used in a device obtained by modifying the voice guidance device 1 of the above embodiment as follows. Modifications of the voice guidance device 1 of the above embodiment will be described below.

The hardware configuration of the voice guidance device 1 according to this modified example is basically the same as that of the above-described embodiment except that the warning light is provided at a position where the operator can easily see it, so the description is omitted. In the voice guidance device 1 of this modified example, the table used for reproducing voice data is configured as follows. FIG. 9 is a diagram showing an example of a table used for reproducing voice data in the voice guidance device 1 according to this modification. In a table that the reproduction processing unit 4 refers to when reproducing audio data, for example, as shown in FIG. There is a specified time to put it in.

FIG. 10 is a diagram showing an example of correspondence relationships between various procedures performed in the brazing work and the content (detailed version) of voice guidance provided by the voice guidance device 1 according to the modification. Also, FIG. 11 is a diagram showing an example of the correspondence relationship between various procedures performed in the brazing work and the content (simplified version) of voice guidance provided by the voice guidance device 1 according to the modification. In the voice guidance device 1 according to this modification, the length of the brazing material to be consumed is determined by the reproduction processing unit 4 referring to the table of FIG. (for example, if the pipe diameter is 6.35φ, the length of the brazing material to be consumed is 2 cm) is obtained, and the audio data of the information is reproduced. In addition, the reproduction processing unit 4 provides voice guidance of the timing of inserting the brazing material in the process of step S103. Further, the reproduction processing unit 4 provides voice guidance on the upper limit of the heating time in the brazing work. As the content of the voice guidance, for example, detailed content as shown in FIG. 10 and simple content as shown in FIG. 11 are prepared. In the voice guidance device 1 of this modified example, voice guidance can be switched between a detailed version and a simplified version in order to make the content of the voice guidance suitable for the skill of the operator. In the voice guidance device 1 of this modified example, in order to prevent the operator from failing to hear the voice guidance, a light emitting means such as an indicator lamp or a rotating light is illuminated at the same time as the voice guidance. Only the light may be emitted, or only the light emitted by the light emitting means may be used. It is preferable that any one of "audio only", "audio and light emission", and "light emission only" can be switched by, for example, a changeover switch.

The length of the brazing material that is voice-guided varies according to the pipe diameter input in step S101. For example, if the pipe diameter is input as 9.52φ in step S101, the length of the brazing material to be consumed is guided as 3 cm in step S103, and if the pipe diameter is input as 12.7φ in step S101, At step S103, it is informed that the length of the brazing material to be consumed is 4 cm. The same applies when other pipe diameters are input in step S101.

FIG. 12 is a diagram showing a comparison of timings of reproducing audio data in this modified example. As can be seen by comparing "At normal temperature" and "At low temperature" shown in FIG. 12, when the ambient temperature of the space in the work site where the brazing work is performed becomes lower than that at normal temperature, the start of heating is announced by voice. The time until the introduction of the brazing filler metal is guided becomes longer. In addition, as can be seen by comparing "At normal temperature" and "At high temperature" shown in FIG. The time from guidance to introduction of brazing material is shortened.

In the voice guidance device 1 according to the present modification, since the length of the brazing material to be consumed is announced before starting the brazing work, an appropriate amount of brazing material can be prepared in advance. When the length of the brazing filler metal is guided by the voice guidance device 1 according to the present modification, the worker can, for example, bend the brazing filler metal 11 at the length of the guided brazing filler metal during the brazing work. It is possible to easily grasp the remaining length of the brazing material 11 to be brazed. By using the voice guidance device 1 according to the present modified example, the operator can easily braze an appropriate amount of brazing material, so that an appropriate amount of brazing material can be attached to the connecting portion of the pipe.

When the appropriate amount of brazing material is applied to the pipe connection, a fillet is properly formed in the pipe connection. Therefore, it is possible to minimize the possibility of defective brazing at the connecting portion of the pipe.

In addition, in the voice guidance device 1, in the voice guidance in step S103, after guiding the end of heating, voice guidance prompts cooling of the brazed portion with a wet cloth, and sealing of the brazing material to prevent deterioration of the brazing material due to moisture absorption. Voice guidance may be provided to prompt management. In addition, the voice guidance device 1 may guide the required remaining amount of the brazing material during the brazing work.

Further, the voice guidance device 1 may guide the part to be roasted with the burner. In this case, for example, when brazing a pipe extending in the lateral direction, after guiding the lower part of the pipe that is not easy to burn with a burner to burn, the pipe that is easy to burn with a burner. It is preferable to guide the upper part of the toasting. The guidance to change the part to be seared by the burner from the lower part of the pipe to the upper part is, for example, detected by detecting the operation of the start button that is pressed when the lower part of the pipe is started to be seared, and then starting timing. , and a method of performing timing when a predetermined time has elapsed after the start of clocking.

In addition, when the contents of guidance correspond to the form of piping in this way, whether the piping to be brazed is vertical or horizontal, for example, the content of input requested to the worker, or the photographing It is preferable to make the determination based on automatic determination such as image analysis of the pipe that has been installed.

By the way, although the above-described embodiments and modifications are voice guidance devices, the above-described voice guidance device 1 may provide guidance equivalent to the above-described voice guidance by visual notification means such as indicator lamps and screen displays instead of voice. can be When the voice guidance function is omitted, the voice guidance device 1 of the above-described embodiment and modifications can be regarded as a guidance device rather than a voice guidance device.

In a form in which guidance equivalent to the above-described voice guidance is provided by visual notification means such as an indicator light or a screen display instead of voice, since the bone conduction headphones 7 are not worn by the worker, the visual notification means is visible to the worker. It should be fixed in a comfortable position. For example, when the visual notification means is a display provided on the housing of the guidance device, or when the visual notification means is a display lamp, the visual notification means is fixed at a position where the operator can easily see it. Clips, magnets, bendable flexible rods, and other fixing means are used as means for fixing the guide device to the worker's clothing, a nearby frame, or the like. Further, for example, when the visual notification means is a head-mounted display, a strap or the like is used for fixing the head-mounted display to the operator's head. When the visual notification means is a display or indicator light provided on the housing of the guide device, the display or indicator light is hinged to the housing of the guide device so that the orientation of the display or indicator light can be freely changed. It is preferable that it is attached via such as. In addition, when the visual notification means is a display or an indicator lamp, it prevents the notification from being obscured by the light of the burner flame during the brazing work, and prevents the notification light from affecting the color of the burner flame. Therefore, it is preferable that the display and the indicator lamp are provided with a canopy.

In addition, when guidance equivalent to the above-described voice guidance is provided by visual notification means, as shown in FIG. 10 and FIG. It is preferable to provide functions for changing the speed, displaying the remaining time count, changing the display color, and showing other changes over time. When the specific timing is expressed by changing the flashing speed, the flashing speed is gradually slowed down, and at the moment when the specific timing is reached, the flashing is switched to lighting. Examples include a form in which blinking is switched to extinguish at the moment when is coming, and other forms. In addition, when a specific timing is expressed by changing the display color, the color is gradually changed from dark to bright, and at the moment when the specific timing is reached, the bright color is switched to the dark color. Examples include a form in which a dark color is gradually changed to a dark color, and the dark color is switched to a bright color at the moment when the specific timing is reached, and other forms. When a specific timing is represented by an indicator light, in addition to changing the lighting state of the indicator light itself, physical structures such as a reflector that circles around the light source in a rotating light or a cover that covers the light source from the operator side can be used. mechanism may be used. When the specific timing is represented by a revolving light, for example, it can be changed in the rotational speed of a reflecting mirror that revolves around the light source or stops rotating. Further, when the specific timing is represented by the opening and closing of the cover, for example, by gradually closing the gap of the cover that covers the light source from the operator side, the light leaking from the gap is gradually weakened.

In addition, when guidance equivalent to the above voice guidance is performed by visual notification means, the guidance of the part to be roasted with the burner is, for example, detected by detecting the operation of the start button pressed when the lower part of the pipe is started to be roasted. After that, when a predetermined time elapses after starting the time measurement, the first light emission signal is output, and after that, a predetermined time (for example, the timing at which the color of the burner changes to orange) is reached. A second light emission signal may be output when the time elapses. In this case, it is preferable that the first light emission signal and the second light emission means have mutually different colors or mutually different light emission patterns. If the guidance to the worker is realized by simple input/output such as operation of the start button and light emission of the signal, the hardware configuration of the guidance device can be simplified.

By the way, in the above embodiments and modifications, guidance is provided according to the thermal information of the work site. The brazing material length corresponding to the input pipe diameter may be guided.
