Description

[Technical Field]

[0001] The present invention relates to a work support system, a work support device, and a work support program. [Background technology]

[0002] Work at repair shops such as automobile repair factories and dealerships involves inspecting various items according to, for example, the type of vehicle and the inspection period. One such inspection task involves tightening fasteners such as bolts installed at various locations on the vehicle to be repaired with a predetermined tightening torque (Patent Document 1).

[0003] In this tightening work, the mechanic first opens the thick work manual to the page for the relevant inspection location, checks the specified tightening torque for the bolt written on that page, sets that specified tightening torque as the target torque on the torque wrench, and begins work using that torque wrench.

[0004] However, with this type of work method, the specified tightening torque must be confirmed and the target torque must be set manually, which is prone to human error and also places limitations on how much work efficiency can be improved.

[0005] This problem is not limited to tightening work using a torque wrench, but can occur in a variety of inspection work using tools, such as measuring tire tread depth or remaining brake fluid and comparing it with inspection standards. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 5806184 Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, the present invention has been made to solve the above-mentioned problems, and its main objective is to prevent errors in setting target values ​​when working in a maintenance shop, while also improving work efficiency. [Means for solving the problem]

[0008] In other words, the work support system of the present invention is a work support system that supports work at a maintenance yard, and is characterized by comprising a support information storage unit that stores identification information that identifies the maintenance object, inspection location information that indicates the inspection location of the maintenance object, and support information that is linked to a target value that is predetermined in accordance with the work at the inspection location, an identification information receiving unit that receives the identification information, an inspection location receiving unit that receives the inspection location information, and a target value setting unit that acquires and sets the target value linked to the identification information and the inspection location information.

[0009] With a work support system configured in this manner, by inputting the identification information of the maintenance object and the inspection location information, the target values ​​linked to this information are automatically set, eliminating the need for workers to manually check or manually set the target values. This prevents mistakes in setting target values ​​when working in the maintenance yard, and also improves work efficiency.

[0010] If the set target value can be changed by the operator, there is a possibility that an inappropriate target value may be set due to, for example, an operator's erroneous operation. Therefore, it is preferable that the target value set by the target value setting unit cannot be changed by an operator. With this configuration, it is possible to prohibit the operator from changing the target value, thereby improving manageability and traceability.

[0011] It is preferable that when the identification information receiving unit receives the identification information and the inspection location receiving unit receives the inspection location information, but the target value is not set by the target value setting unit, the worker can input the target value. With this configuration, it is possible to flexibly respond even when communication with the support information storage unit is not established, for example.

[0012] In order to make it possible to easily input the identification information, it is preferable to further comprise an input means for inputting the identification information, or an imaging means for imaging the identification code for reading the identification information.

[0013] As a more specific embodiment, the object to be serviced may be a vehicle, and the identification information may be a character string indicating the vehicle identification number of the vehicle.

[0014] Furthermore, the work support device of the present invention is a work support device that supports work in a maintenance yard, and constitutes a work support system together with a support information storage unit that stores identification information that identifies a maintenance object, inspection location information that indicates an inspection location for the maintenance object, and support information linked to a predetermined target value according to the work at the inspection location, and is characterized by comprising an identification information receiving unit that receives the identification information, an inspection location receiving unit that receives the inspection location information, and a target value setting unit that acquires and sets the identification information and the target value linked to the inspection location information.

[0015] Furthermore, the work support program of the present invention is a work support program that supports work at a maintenance facility, and is characterized in that it causes a computer to perform the functions of a support information storage unit that stores identification information that identifies the maintenance object, inspection location information that indicates the inspection location of the maintenance object, and support information that is linked to a predetermined target value depending on the work at the inspection location, an identification information receiving unit that receives the identification information, an inspection location receiving unit that receives the inspection location information, and a target value setting unit that acquires and sets the identification information and the target value linked to the inspection location information.

[0016] Such a work assistance device and work assistance program can achieve the same effects as the work assistance system described above. [Effects of the Invention]

[0017] According to the present invention configured in this manner, it is possible to prevent mistakes in setting target values ​​during work at a maintenance shop, and further to improve work efficiency. [Brief explanation of the drawings]

[0019] Hereinafter, an embodiment of a work support system according to the present invention will be described with reference to the drawings.

[0020] The work support system 100 according to this embodiment is used in a repair shop such as an automobile repair shop or an automobile dealership, and supports work performed by a worker such as a mechanic. Note that the repair object Z in this embodiment is a vehicle such as a two-wheeled vehicle or a four-wheeled vehicle.

[0021] Specifically, as shown in FIG. 1, this work support system 100 includes a support information storage unit 10 that stores support information including various data related to the maintenance object Z, and a work support device 20 that is operated by a worker to acquire support information from the support information storage unit 10.

[0022] <Support information storage section 10> First, the support information storage unit 10 will be described. The support information storage unit 10 is set in a predetermined area of ​​a memory external to the work support device 20.

[0023] This support information storage unit 10 stores various data related to the maintenance object Z, specifically, for example, data showing past inspection results and data showing the warranty details at the time of vehicle purchase.

[0024] The support information storage unit 10 stores the support information received by the work support device 20 during the inspection work, and the worker can proceed with the inspection work based on this support information.

[0025] As shown in Figure 2, the support information is a combination of identification information that identifies the maintenance object Z, inspection location information that indicates the inspection locations of the maintenance object Z, and target values ​​that are predetermined according to the work to be done at the inspection locations.

[0026] The identification information is unique information that is assigned in advance to each maintenance object Z. In this embodiment, the maintenance object Z is a vehicle such as a two-wheeled vehicle or a four-wheeled vehicle, and a character string indicating an individual vehicle identification number assigned to each vehicle is used as the identification information. Examples of the vehicle identification number include, but are not limited to, the automobile registration number or vehicle number, which are numbers written on license plates, or the chassis number.

[0027] The inspection location information indicates the locations to be inspected during various inspection work on the maintenance object Z, such as the locations to be inspected during regular inspections, the locations to be inspected during oil changes, the locations to be inspected during filter changes, or the locations to be inspected during specific maintenance on the maintenance object Z.

[0028] In this embodiment, the names of the components of the maintenance object Z are used as the inspection location information. More specifically, as shown in FIG. 3, the names indicate fastening points such as the front axle nut, front axle clamp bolt, torque rod, and rear caliper pad pin.

[0029] The target value is a physical quantity that serves as a target when measuring an inspection point using tool X. In this embodiment, as described above, the inspection points are a plurality of fastening points, and the tightening torque when tightening each fastening point using a torque wrench is set as the target value. More specifically, if the specified torque set for the fastening point is 100 Nm, the target value here is set as a value with a range, for example, from 95 Nm to 105 Nm. However, the target value does not need to have a range.

[0030] If the inspection point is a tire, the target value may be set to the tire groove depth measured using a depth gauge, and if the inspection point is a brake pad, the target value may be set to the remaining amount of brake pads measured using a measuring tool such as a caliper. Examples of such target values ​​include threshold values ​​that serve as a guide for replacing tires or brake pads.

[0031] In this way, the support information in this embodiment is a combination of identification information, inspection location information, and target values, such as a character string indicating the vehicle's chassis number, the names of multiple tightening points provided on the vehicle, and the designated tightening torques that are pre-set for each tightening point.

[0032] <Work support equipment 20> Next, the work support device 20 will be described. The work support device 20 is a portable or stationary terminal device such as a tablet, smartphone, or laptop computer equipped with a display D, a CPU, and memory, and performs at least the functions of an identification information receiving unit 21, an inspection location receiving unit 22, and a target value setting unit 23 based on a program stored in the memory, as shown in FIG. 4.

[0033] The identification information receiving unit 21 receives input identification information. Examples of an embodiment for inputting identification information include an embodiment in which the work support device 20 is provided with an input means such as a touch panel or a keyboard, or an embodiment in which an identification code for reading the identification information is provided and an imaging means such as a camera for capturing an image of the identification code is provided.

[0034] In this embodiment, for example, an identification code printed on the vehicle inspection certificate of the vehicle to be serviced Z, or the license plate of the vehicle that is the vehicle to be serviced Z, is captured by a camera, and the vehicle's chassis number is output as identification information to and accepted by the identification information acceptance unit 21. Note that the identification information acceptance unit 21 may accept the vehicle registration number or vehicle number itself written on the license plate as identification information, or may accept the chassis number linked to the vehicle registration number or vehicle number as identification information.

[0035] The inspection location receiving unit 22 receives input inspection location information. As an embodiment for inputting inspection location information, as shown in Fig. 3, the work support device 20 may be provided with an input means such as a touch panel or a mouse for selecting one of a plurality of inspection locations.

[0036] In this embodiment, the names of multiple fastening locations are displayed on the display D of the work support equipment 20, and when the worker selects one of them, for example via a touch panel, the name of the fastening location is output to the inspection location reception unit 22 as inspection location information and accepted.

[0037] The target value setting unit 23 acquires and sets a target value linked to the identification information and the inspection location information.

[0038] More specifically, the target value setting unit 23 first obtains the target value linked to the identification information received by the identification information receiving unit 21 and the inspection location information received by the inspection location receiving unit 22 from the support information storage unit 10.

[0039] Then, the target value setting unit 23 sets the acquired target value in the work support device 20 as a target for the measurement value to be measured using the tool X in the next inspection work, and displays it on the display D of the work support device 20 as shown in FIG. 5.

[0040] The target value set by the target value setting unit 23, in other words, the target value displayed on the display D by the target value setting unit 23, cannot be changed by the worker. In other words, the work support device 20 of this embodiment does not include an input means for changing the target value set by the target value setting unit 23.

[0041] The target value setting unit 23 of this embodiment sets a designated tightening torque that has been set in advance for each fastener as a target value, and as shown in Figure 5, the tightening torque that is the target value is displayed on the measurement screen on the display D during the tightening work.

[0042] However, if the target value setting unit 23 is configured to acquire the target value from the external support information storage unit 10 as described above, when communication between the work support device 20 and the support information storage unit 10 is not established, the target value setting unit 23 cannot acquire the target value, and the target value is not set.

[0043] Therefore, as shown in FIG. 6, the work support device 20 of this embodiment is configured to enable the worker to input a target value when the target value setting unit 23 does not set a target value even though the identification information receiving unit 21 receives identification information and the inspection point receiving unit 22 receives inspection point information (hereinafter also referred to as when setting is not possible).

[0044] More specifically, when the setting is not possible as described above, the operator can input the target value via input means 20a such as a touch panel or keyboard, and this input target value is set by target value setting unit 23. In other words, this input means 20a functions only when the setting is not possible.

[0045] Here, as shown in Fig. 6, a list of multiple target values ​​is displayed, and one target value can be selected from among them, and when it is not possible to set a target value, the target value selected by the operator is set. Note that it is also possible to allow the operator to input and set any value as the target value.

[0046] Once the target value is set by the target value setting unit 23 or the worker in this manner, the worker is ready to start inspection work using the tool X.

[0047] When a worker tightens a fastener using a torque wrench, the actual tightening torque in the tightening operation is measured by the torque wrench or a torque measuring device attached to the wrench.

[0048] The measured value of this tightening torque is transmitted from the torque wrench or torque measuring device to the work support device 20 and displayed on the measurement screen on the display D of the work support device 20, for example, in real time.

[0049] More specifically, the work support device 20 of this embodiment further includes a function as a measurement value receiving unit 24 that receives measurement values ​​of the tightening torque, as shown in Fig. 4, and the measurement values ​​received by this measurement value receiving unit 24 are displayed one after another on the same screen (specifically, the measurement screen) as the target values ​​described above. This allows the worker to proceed with the work while comparing the target values ​​with the measured values.

[0050] According to the work support system 100 configured in this manner, when a worker inputs the identification information and inspection location information of the maintenance object Z, the target value linked to this information is automatically set, thereby eliminating the need for the worker to manually check or set the target value. This prevents mistakes in setting target values ​​when working in the maintenance yard, and also improves work efficiency.

[0051] Furthermore, since the target value set by the target value setting unit 23 cannot be changed by the worker, it is possible to prohibit the worker from changing the target value, thereby improving manageability and traceability.

[0052] Furthermore, even when setting is not possible, the worker can input a target value, so that even when communication between the work support device 20 and the support information storage unit 10 is not established, a flexible response can be made.

[0053] Furthermore, since the work support device 20 is provided with an input means for inputting identification information or an imaging means for imaging an identification code for reading the identification information, the worker can easily input the identification information.

[0054] The present invention is not limited to the above-described embodiment.

[0055] For example, in the above embodiment, the work support system 100 has been described as being used for tightening work using a torque wrench, but it may also be used for measuring tire groove depth using a depth gauge, or for measuring the remaining amount of brake pads using a measuring tool such as a vernier caliper.

[0056] In the above embodiment, the target value setting unit 23 sets the target value within the work support device 20, but if the tool X is a digital tool that can communicate with the work support device 20, the target value may be transmitted to the digital tool and set for the digital tool.

[0057] In the above embodiment, the identification information is input using an input means such as a touch panel or a keyboard or an imaging means, but it may also be input by voice using a microphone or the like.

[0058] The maintenance object Z is not limited to a vehicle, but may also be a moving object such as a bicycle, a train, an airplane, a ship, or an agricultural machine, or various industrial machines.

[0059] Furthermore, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
