The initial operation by the outsourcer, the recovery operation by the outsourcer, and the maintenance operation by the manufacturer are merely examples, and are not particularly limited to the above-described operation contents.

  Next, with reference to FIG.1 and FIG.2, a series of operation | movement regarding the malfunction response system 1 of Example 1 is demonstrated. When a failure occurs in the machine tool 5 used by the user (step S1), the user sends the initial request information S1 for requesting the initial operation from the user side contact device 11 to the manufacturer in order to request the recovery of the machine tool 5. To the communication device 21 (step S2). When the manufacturer receives the initial request information S1 from the user, the manufacturer transmits the initial request information S2 from the manufacturer-side contact device 21 to the consignee-side contact device 31 in order to expedite the initial task handling personnel to the user. When the contractor receives the initial request information S2 from the manufacturer, the contractor promptly dispatches the initial response work personnel who are traveling around the user's location to the user.

  When the commissioned initial work support staff arrives at the user (step S3), the initial work work support staff performs the initial work using the communication terminal 32. First response work personnel who arrive at the user first listen to the state of the malfunction of the machine tool 5 (step S4). More specifically, in step S4, the initial operation work support personnel told the user in which part the trouble of the machine tool 5 occurred, and what was the driving situation until the trouble occurred. Listening to it. Specifically, in step S4, for example, the operation of the predetermined part, the driving sound of the predetermined part, the current value of the motor serving as the power source of the driving unit, the ON / OFF timing of the limit switch, the hydraulic pressure, the oil temperature, For example, the initial response work support staff listens to the differential pressure, or the initial response work support staff acquires an operation history at the time of occurrence of a malfunction recorded in a recorder provided in advance in the machine tool 5.

  Subsequently, the initial operation work corresponding person confirms whether or not the defect of the machine tool 5 that has been heard has a reproducibility of the defect (step S5). At this time, the initial task handling personnel may acquire information on the malfunction of the machine tool 5 by the information acquisition unit 45 by operating the communication terminal 32 together with the confirmation of the reproducibility of the malfunction. When the reproducibility of the defect is confirmed, the person in charge of the initial operation operates the communication terminal 32 that is carried and inputs the defect information of the machine tool 5 to the display unit 42 of the communication terminal 32 as shown in FIG. The input screen D1 shown in FIG.

  As shown in FIG. 3, this input screen D1 is a screen for inputting defect information of the machine tool 5 that has been heard in step S4 and whose reproducibility has been confirmed in step S5. The input screen D1 displays a title for selecting a defect content, an item D1a for inputting a defect location where the defect has occurred, and an item D1b for inputting the defect content occurring at the defect location. And are displayed. These items D1a and D1b are displayed in, for example, a pull-down menu format, and the item D1b for inputting defect contents displays defect contents that are highly related to the defect part input in the item D1a. As described above, the input screen D1 displays the items D1a and D1b as a list, and the initial operation work support personnel touch the items D1a and D1b to display defect information of the machine tool 5.

On the confirmation screen D2, a title for prompting confirmation of the status of the defective part is displayed, and an item D2a for inputting the status of the defective part is displayed. This item D2a is displayed, for example, in a checklist format, and lists and displays the causes of defects estimated based on the defect information input on the input screen D1 shown in FIG.

  Here, as the item D2a for inputting the status of the failure location, for example, when the failure location is an automatic tool changer, the hydraulic oil flow rate decreases, the pressure loss before and after the hydraulic oil filter increases, the hydraulic fluid decreases, the hydraulic fluid viscosity Increase. As a method of confirming the situation of these trouble spots, the indicated value of the hydraulic oil flow meter, the indicated value of the differential pressure gauge before and after the filter, the indicated value of the hydraulic oil level gauge, the set value of the hydraulic oil temperature setting device, and the like are displayed.

  When information related to the status confirmation of the defect location is input on the confirmation screen D2, the communication terminal 32 determines whether or not the restoration work by the outsourcer can be handled based on the failure information regarding the location of the malfunction location and the malfunction location. (Step S8). If it is determined that the restoration work by the outsourcer is available (step S9: Yes), the communication terminal 32 displays the notification screen D3a shown in FIG. 5 and responds by the restoration work by the outsourcer (step S10). . On the other hand, when it is determined that the restoration work by the contractor cannot be handled (step S9: No), the communication terminal 32 displays the request screen D3b shown in FIG. Not performed (step S13).

  In this way, the initial operation support staff performs the initial operation using the communication terminal 32 to determine whether or not the recovery operation by the consignee is possible. In the first embodiment, the initial operation work support personnel performed the initial operation using the communication terminal 32, but may perform the initial operation while keeping in contact with the manufacturer.

  As shown in FIG. 5, the notification screen D3a displays that the restoration work by the outsourcer can be handled. In step S10, if the communication terminal 32 determines that the restoration work is performed by the outsourcer, the communication terminal 32 displays the work support screen D4 shown in FIG. 6, and the initial work work support person performs the restoration work (step S11).

  As shown in FIG. 6, the business support screen D4 is a screen for notifying the initial operation work support personnel of the procedure for the recovery operation in order to recover the identified defective part. On the business support screen D4, a title for prompting the recovery operation for the initial operation work support personnel is displayed, and a recovery operation procedure D4a is displayed.

  The initial task handling personnel recovers the machine tool 5 by performing a recovery operation according to the procedure displayed on the task support screen D4 (step S12). In the first embodiment, the work support personnel perform the maintenance work by displaying the work support screen D4 on the communication terminal 32. However, the present invention is not limited to this configuration. For example, the manufacturer may contact the manufacturer, and the initial operation work support personnel may perform maintenance work according to the manufacturer's instructions.

  On the other hand, if no response is made in the restoration work by the consignee in step S13, a request screen D3b is displayed on the communication terminal 32 as shown in FIG. The request screen D3b is a screen for requesting maintenance work by the manufacturer. The request screen D3b displays options for whether or not to request maintenance work by the manufacturer. When the initial operation staff member selects an option for requesting maintenance work by the manufacturer, the communication terminal 32 transmits maintenance request information for requesting maintenance work by the manufacturer to the manufacturer (step 14). . In step S14, along with the maintenance request information, the failure information of the machine tool 5 acquired by the information acquisition unit 45 or the failure information specified in the initial operation may be transmitted to the manufacturer's server 22 and the work terminal 23. .

  When the manufacturer receives the maintenance request information from the subcontractor, the manufacturer dispatches maintenance personnel to the user.
