The door 14 is arranged so as to allow access to the component box 13 when removal of the component from the component box 13 is permitted, and access to the component box 13 is permitted when removal of the component from the component box 13 is not permitted. Arranged so that it can not. The terminal 6 is provided with a lamp 62. The lamp 62 is, for example, an LED (Light Emitting Diode) lamp.

The drive control of the door 14 and the lighting control of the lamp 62 are performed by the production support device 2. That is, the production support apparatus 2 instructs the parts box 13 by turning on the lamp 62 with respect to the terminal 6 of the parts box 13 storing the parts related to the assembly work that has arrived in accordance with the work procedure. The door 14 is opened to allow the part to be removed from the parts box 13 and to put the part into a usable state.

For each part box 13, parts to be stored in the part box 13 are determined. The component shelf 12 is divided into a plurality of regions in which a plurality of component boxes 13 are respectively arranged. FIG. 4 is a diagram illustrating an example of each region in the component shelf 12. FIG. 4 illustrates the surface of the component shelf 12 on which the component box 13 is installed, and illustrates _six regions Y ₁ to Y ₆ as regions where the component box 13 can be arranged. In the following, each region or the like is identified from Y ₁ by the symbols of Y _6, Y ₆ from Y ₁ is described as a position information. The position information may be any information as long as it is information indicating the installation position on the parts shelf 12. For example, the position information may be a number indicating the numbered region from the left when the parts shelf 12 is viewed from above. Alternatively, it may be a coordinate value in a coordinate system in which a certain reference in the plane when the parts shelf 12 is viewed from above is the origin. Specifically, for example, when the number indicating the number of the region from the left when the parts shelf 12 is viewed from above is used as the position information, Y ₁ is “1” and Y ₂ is “2”. ". The parts shelf 12 is provided with labels 131 corresponding to the respective areas, and these labels 131 indicate first identifiers that are identifiers corresponding to the respective areas. The first identifier is an identifier including a first component identifier that is identification information indicating a component to be stored in the component box 13 arranged in each area, and is in a format readable by the reader 9 described later.

The reader 9 shown in FIGS. 1 and 2 is used when the parts box 13 in which the parts are stored is arranged in a predetermined area of the parts shelf 12. Each component box 13 is given a second identifier including a second component identifier which is identification information indicating a component to be stored in each component box 13. For example, a label indicating the second identifier is attached to the component box 13, whereby the second identifier is given to the component box 13. Further, a third identifier including a third component identifier that is identification information indicating the component is assigned to the component. For example, a label indicating the third identifier is attached to the component, whereby the third identifier is given to the component. The second identifier and the third identifier can be read by the reader 9. The identification information indicating each component is held by the production support apparatus 2 and is information indicating the type of component. The identification information indicating each component may be determined in advance or may be set by an operator as will be described later. When the component is stored in the correct component box 13 and the component box 13 is arranged in the correct region, the above-described first component identifier, second component identifier, and third component identifier match. Here, the phrase “arranged in the correct area” means that the element is arranged in an area defined by component information described later.

When the worker places the parts box 13 containing the parts used for assembly on the parts shelf 12, the operator assigns the first identifier assigned to the area in the parts shelf 12 by the reader 9 and the parts box 13. The second identifier assigned to the component and the third identifier assigned to the component are read. The reader 9 transmits the first to third component identifiers included in the first to third identifiers to the production support apparatus 2.

When the first to third component identifiers coincide with each other, the production support device 2 turns on the lamp 62 of the terminal 6 provided for the area and opens the door 14 to The box 13 can be placed in the area. If the first to third component identifiers do not match each other, the production support apparatus 2 does not turn on the lamp 62 of the terminal 6 provided for the area and also closes the door 14. As a result, the parts can be correctly arranged at a predetermined location on the parts shelf 12.

The driver 5 is an electric driver for screw tightening. In FIG. 1,

drivers

5 a, 5 b, and 5 c are shown as the plurality of drivers 5. In the arrangement configuration example shown in FIG. 2, the plurality of drivers 5 are respectively suspended using a plurality of spring balancers 39.

FIG. 5 is an enlarged view of the driver 5. The driver 5 includes a lamp 61 as shown in FIG. The lamp 61 is, for example, an LED lamp. The lighting of the lamp 61 is controlled by the production support device 2. That is, the production support apparatus 2 turns on the lamp 61 of the driver 5 that can be used in the order according to the work procedure. The production support apparatus 2 does not turn on the lamp 61 of the driver 5 that is out of order and cannot be used.

The lamp 61 is provided with a mechanical lock on the spring balancer 39 for suspending the driver 5 in addition to the indication of the driver 5 to be used by lighting, and the production support device 2 releases the lock to the driver 5 whose turn has arrived. Thus, the driver 5 can be put into a usable state, and the driver 5 can be put into the unusable state by maintaining the lock for the driver 5 whose order has not arrived. At this time, both the drivers 5 are supplied with power, and by applying a mechanical lock to the drivers 5, the power supply to the plurality of drivers 5 is controlled according to the work procedure. Only the driver 5 according to the procedure can be made available. FIG. 6 is a diagram illustrating an example of a mechanical lock provided on the spring balancer 39. As shown in FIG. 6, the length of the wire 394 is limited to a predetermined value or less by adopting a configuration capable of stopping the rotation of the gear-like rotating portion 391 that feeds the wire 394 of the spring balancer 39. In the configuration shown in FIG. 6, the spring balancer 39 includes a restraining portion 393 that can be rotated by an actuator 392. FIG. 6 shows a locked state, and the suppression unit 393 has a shape extending in a direction toward the center of the rotation unit 391, and the rotation of the rotation unit 391 is suppressed. In the unlocked state, the restraining unit 393 rotates by the actuator 392 and stops at a position where the rotation of the rotating unit 391 is not hindered. The actuator 392 rotates the suppression unit 393 according to an instruction indicating whether to lock or release the lock from the production support apparatus 2. In the locked state, the operator cannot draw the driver 5 connected to the wire 394 close to the hand. That is, the driver 5 enters a state where it cannot be used by the operator, that is, an unusable state. The lock may be provided on the stand 40 of the driver 5 instead of being provided on the spring balancer 39. In this case, for example, a wire or the like that connects the stand 40 and the driver 5 is provided, and the stand 40 is provided with a mechanism that can limit the same length as the spring balancer 39 shown in FIG. Further, without using the spring balancer 39, the driver 5 may be housed in a separate box, and the mechanical lock state and the unlocked state may be switched by opening and closing the box door. In addition, the production support device 2 mechanically controls a switch for turning the driver 5 on or off, and for the driver 5 that has arrived in the order, the driver switch is turned on so that the driver 5 can be used. For the driver 5 that has not arrived, the driver can be turned off by turning off the driver switch.

The driver 5 also has a function of notifying the production support device 2 of the start of rotation and the arrival of the designated torque when the driver 5 starts rotating and when the driver 5 reaches a predetermined torque. Here, the predetermined torque is a torque generated in the driver 5 when the screw tightening is completed. The production support device 2 obtains the rotation time from the start of rotation until reaching a predetermined torque, or the rotation speed from the start of rotation until reaching a predetermined torque. The rotation time is obtained from the time difference from the start of rotation of the driver 5 to when the driver 5 reaches a predetermined torque. The number of rotations is obtained from the rotation time and the rotation speed. The rotation speed is based on the specifications of the driver 5. The production support device 2 determines whether or not the screw tightening is based on whether or not the rotation time is within the set rotation time range, or based on whether or not the rotation number is within the set rotation speed range. Can be determined.

The buzzer 7 sounds under the control of the production support device 2. The production support device 2 determines whether or not the screw tightening is successful, and uses the buzzer 7 to notify the determination result of whether or not the screw tightening is sound. For example, the production support apparatus 2 may be configured to sound the buzzer 7 when the determination result is unacceptable, and not to sound the buzzer 7 when the determination result is acceptable. Alternatively, the production support device 2 causes the buzzer 7 to sound with the sound of the first frequency when the determination result is unacceptable, and the second different from the first frequency when the determination result is acceptable. The buzzer 7 may be sounded at a frequency.

The indicator lamp 8 is turned on under the control of the production support device 2. The production support device 2 determines whether or not the screw tightening is successful, and notifies the result of the screw tightening determination by turning on the indicator lamp 8. The indicator lamp 8 lights up a different color depending on whether or not the screw tightening determination is accepted. For example, when the screw tightening is passed, the indicator lamp 8 is lit in green, and when the screw tightening is not passed, the indicator lamp 8 flashes in red.

The input switch 10 receives an input of a signal indicating the end of work. The worker presses the input switch 10 every time work is completed. A signal indicating the end of work is input to the production support apparatus 2.

The management server 11 is communicably connected to the production support apparatus 2 via a network. The production support apparatus 2 transmits work history information obtained in the assembly work to the management server 11. The work history information includes information on determination results regarding pass / fail during screw tightening, work start time, work end time, and accumulated work time.

Although not shown in FIG. 1, generally, a plurality of production support apparatuses 2 are connected to the management server 11. The management server 11 collects work history information from a plurality of production support apparatuses 2.

Next, details of the configuration of the production support apparatus 2 will be described. The production support apparatus 2 can be realized by a computer that operates according to a sequence program. FIG. 7 is a diagram illustrating a hardware configuration example of the production support apparatus 2. As shown in FIG. 7, the production support apparatus 2 includes a processor 50, a memory 51, an input interface 52, an output interface 53, a communication interface 54, and a bus 55.

The processor 50 is generally a CPU (Central Processing Unit), and the memory 51 is generally a RAM (Random Access Memory) and a ROM (Read Only Memory). The input interface 52 receives input from an input device (not shown) including a keyboard and a pointing device. The output interface 53 receives an output to an output device including the display device 3. The communication interface 54 is a circuit for performing communication via a network. The bus 55 connects the processor 50, the memory 51, the input interface 52, the output interface 53, and the communication interface 54 to each other.

The production support device 2 is realized by executing a sequence program on a computer. The sequence program is stored in the memory 51, and the processor 50 reads the sequence program from the memory 51 and executes it. The sequence program is a production support program.

FIG. 8 is a block diagram illustrating an example of a functional configuration of the production support apparatus 2. As shown in FIG. 8, the production support apparatus 2 includes a work procedure setting unit 15 that sets a work procedure for a product, a control unit 16 that performs various controls, and a work procedure that is a storage unit that stores work procedure information. The information storage part 20 and the pass / fail determination information storage part 24 which is a memory | storage part which memorize | stores the pass / fail determination information for determining pass / fail of screw fastening are provided. Furthermore, the production support apparatus 2 includes a component information setting unit 22 that sets the component information 26 and a component information storage unit 25 that is a storage unit that stores the component information 26. Although details will be described later, the part information 26 is information including a part used in the assembly work of the product and a storage place where the part is stored for each assembly work procedure. The product work procedure is a product assembly work procedure, that is, an assembly work procedure. The control unit 16 includes a component management unit 17 that manages components, a driver management unit 18 that manages the driver 5, and a pass / fail determination unit 19 that determines pass / fail of screw tightening. The parts management unit 17 includes a parts inspection unit 17a that inspects parts.

The work procedure setting unit 15 receives input of work procedure information 21 by the user of the production support apparatus 2. The work procedure information 21 is information relating to the work procedure of the product assembly work. The work procedure information 21 is input to the production support apparatus 2 as a part of the sequence program or data referenced from the sequence program. The work procedure setting unit 15 stores the input work procedure information in the work procedure information storage unit 20.

The parts management unit 17 manages the availability of the parts used in the product assembly work based on the work procedure information 21 stored in the work procedure information storage unit 20. Based on the work procedure information 21 stored in the work procedure information storage unit 20, the parts management unit 17 sets only the parts used in the assembly work that has arrived in the usable state.

As a specific example of the operation for enabling only the parts used in the assembly work whose order has arrived, the parts management unit 17 stores the parts used in the assembly work whose order has arrived based on the work procedure information 21. The lamp 62 is lit to instruct the terminal box 13 to the terminal 6 of the part box 13 that has been made, and the door 14 is driven so that the part can be taken out from the part box 13. As a result, only the parts used in the assembly work whose order has arrived become usable.

The part inspection unit 17a determines whether or not a part used in the assembly work matches a part specified as a part used in the assembly work.

The component inspection unit 17a receives from the reader 9 the first identifier assigned to the area in the component shelf 12, the second identifier assigned to the component box 13, and the third identifier assigned to the component. receive.

The component inspection unit 17a checks the first to third component identifiers included in the first to third identifiers, and is used for assembly only when the first to third component identifiers match each other. The component box 13 in which the components are stored can be arranged on the component shelf 12. Accordingly, the parts in the parts box 13 arranged on the parts shelf 12 are parts that are guaranteed to match the parts defined as parts used in the assembly work.

In this way, the parts management unit 17 manages the availability of parts in assembly work. The parts management unit 17 also determines whether or not the parts in the parts box 13 arranged on the parts shelf 12 meet the specifications.

The driver management unit 18 controls the power supply to each driver 5 based on the work procedure information 21 that defines the order of power supply to the plurality of drivers 5. After detecting the operation of one of the plurality of drivers 5, the driver management unit 18 supplies power to the next driver 5 among the plurality of drivers based on the work procedure information 21.

When the use of the three

drivers

5a, 5b, and 5c is defined in the order of the driver 5a, the driver 5b, and the driver 5c, the driver management unit 18 supplies power to the driver 5a to operate the driver 5a. After the detection, power is supplied to the driver 5b. As a result, the driver 5b can be used. Even if the driver 5a is in use, after the driver 5a operates, power is supplied to the driver 5b so that the driver 5b can be used. Furthermore, the driver management unit 18 supplies power to the driver 5c after detecting the operation of the driver 5b. As a result, the driver 5c can be used. Even if the driver 5b is in use, after the driver 5b operates, power is supplied to the driver 5c, and the driver 5c can be used.

The pass / fail determination unit 19 performs pass / fail determination of screw tightening based on the pass / fail determination information. As described above, the driver 5 notifies the production support device 2 of the start of rotation and the arrival of the designated torque when the driver 5 starts rotating and when the driver 5 reaches a predetermined torque. Instead of notifying the production support device 2 of the start of rotation and the arrival of the specified torque, the driver 5 determines that the rotation start of the driver 5 and the arrival of the specified torque are determined. By operating the device 3, the display device 3 may notify the production support device 2 of the start of rotation and the arrival of the designated torque. Alternatively, the production support device 2 may monitor the power supplied to each driver 5 and determine the start of rotation and the arrival of the specified torque based on the power. The pass / fail determination unit 19 obtains the rotation time from the start of rotation until reaching a predetermined torque, or the number of rotations from the start of rotation until reaching a predetermined torque. The pass / fail determination information is information indicating a rotation time range in which screw tightening is determined to be acceptable or a rotation speed range in which screw tightening is determined to be acceptable.

The pass / fail determination unit 19 determines that the screw tightening is acceptable when the rotation time is included in the rotation time range, and rejects the screw tightening when the rotation time is not included in the rotation time range. Is determined. The pass / fail determination unit 19 determines that the screw tightening is acceptable when the rotational speed is included in the rotational speed range, and fails the screw tightening when the rotational speed is not included in the rotational speed range. It is determined that

The work procedure setting unit 15 and the component information setting unit 22 are realized by the input interface 52. The control unit 16 is realized by the processor 50. The work procedure information storage unit 20, the pass / fail determination information storage unit 24, and the component information storage unit 25 are each realized by the memory 51.

Next, in S1, the production support apparatus 2 sets the work procedure of the product. That is, the production support apparatus 2 accepts input of work procedure information 21. FIG. 11 is a diagram illustrating an example of a display screen that accepts input of work procedure information. A display screen 101 shown in FIG. 11 is a screen displayed on the display 3 by the work procedure setting unit 15 in S1. The display screen 101 shown in FIG. 11 includes a work procedure input reception area 102 and a next button 107. The next button 107 is a button that is touched by the operator to be used when there is a work following the work displayed in the work procedure input reception area 102. In the example shown in FIG. 11, the operations up to the order 3 are displayed. Therefore, when inputting the operations after the order 4, the operator presses the button 107 by touching the next button 107. When the work procedure setting unit 15 is notified from the display device 3 that the next button 107 has been touched, the work procedure setting unit 15 displays a screen for inputting work in order of 4 or later.

In the work procedure input reception area 102, an order that is a number indicating the order of each work is displayed, and

input windows

103, 104, and 105 for receiving input of information indicating used parts and tools for each order, that is, for each work procedure. Have The information indicating the tool is information indicating the type of the driver 5. The information indicating the used parts is, for example, the model name of the used part. Further, as shown in FIG. 11, the production support apparatus 2 may accept an input of the quantity of used parts. Further, the work procedure input reception area 102 has a work content input button 106 for transitioning to a work content input reception screen for each order. When the work content input button 106 is touched, the work procedure setting unit 15 displays a work content input screen on the display 3. FIG. 12 is a diagram illustrating an example of a work content input screen. The work content input screen 110 shown in FIG. 12 includes

input windows

111 and 112 for inputting a lower limit value and an upper limit value of the screw tightening time, respectively. Further, the work content input screen 110 includes an input window for accepting inputs of the assembly message 113 and the attention point 114. The assembly message 113 is a message related to assembly displayed to the worker, and the attention point 114 is a message indicating the attention point at the time of assembly displayed to the worker. Any method can be used as an input reception method in each input window. For example, a method in which a keyboard is displayed on the display unit 3 by touching each input window and an input is received by the keyboard may be used. A method of displaying a list of various items and accepting selection by a pull-down method may be used.

The display 3 transmits the information received on the display screen 101 and the information received on the work content input screen 110 to the production support apparatus 2. The production support apparatus 2 holds the information received from the display 3 as work procedure information 21. FIG. 13 is a diagram illustrating a configuration example of the work procedure information 21. As illustrated in FIG. 13, the work procedure information 21 includes an order, a used part, a storage location, a tool, and work contents. In addition, as shown in FIG. 11, when the input of the quantity of used parts is also received, the work procedure information 21 includes an order, used parts, quantity, storage location, tool, and work contents. As shown in FIG. 12, the storage location stores the position information of each area in the parts shelf 12 described above. The work content is information received on the work content input screen 110, A, B, C, and D indicate the types of information received on the work content input screen 110 by symbols, and A is the screw tightening time. , B is a lower limit value of the screw tightening time, C is an assembly message, and D is an attention point. Among the work contents, the upper and lower limit values of the screw tightening time are also used as pass / fail judgment information. That is, the production support apparatus 2 stores the upper and lower limit values of the screw tightening time among the work contents in the pass / fail determination information storage unit 24 as pass / fail determination information. In FIG. 13, the work content is included in the work procedure information 21, but the work content may be held in the production support apparatus 2 as other information. In this case, the work content is held in the production support apparatus 2 together with the corresponding work order.

Next, in S2, the production support apparatus 2 determines whether or not the part used in the assembly work matches the part specified as the part used in the assembly work. Specifically, the production support apparatus 2 displays a part management screen for confirming the state of each part using the part information 26. FIG. 14 is a diagram illustrating an example of a display screen 30a that is a component management screen. The display screen 30a of FIG. 14 is the same as the display screen 30 shown in FIG. 11, but the determination result whether the “status” column matches the parts specified as the parts used in the assembly work or not. Has been updated accordingly. The operator causes the reader 9 to read the identifiers assigned to the respective areas of the parts shelf 12, the parts box 13, and the reader 9 in order to confirm whether each part is installed at the correct place. The reader 9 reads a label corresponding to each area of the parts shelf 12 and transmits a first identifier as a result of the reading to the production support apparatus 2. The reader 9 reads the label of the parts box 13 and transmits a second identifier as a result of the reading to the production support apparatus 2. The reader 9 reads the third identifier assigned to the component in the component box 13 and transmits the third identifier to the production support apparatus 2. The parts inspection unit 17a of the production support apparatus 2 includes the first part identifier included in the first identifier assigned to the area in the parts shelf 12 and the second identifier included in the second identifier assigned to the part box 13. By comparing the part identifier of the second part and the third part identifier included in the third identifier assigned to the part, it is determined whether or not the part identifier matches the part defined as the part used in the assembly work. Do. If the first part identifier, the second part identifier, and the third part identifier match, the part inspection unit 17a of the production support apparatus 2 determines that the part is the same as the part defined as the part used in the assembly work. To do. This prevents the parts from being stored in the wrong part box 13 or the parts box 13 containing the parts from being placed at the wrong position on the parts shelf 12.

Next, in S3, the production support apparatus 2 identifies the parts used in the assembly work that has arrived, based on the work procedure.

Next, in S4, the production support apparatus 2 makes only the specified parts usable based on the work procedure. Specifically, the production support apparatus 2 turns on the lamp 62 for the terminal 6 of the parts box 13 in which the parts used in the assembly work that has arrived are stored on the basis of the work procedure information 21 to turn on the parts box. 13 is instructed, and the door 14 is opened to allow the parts to be taken out from the parts box 13. As a result, the operator can take out the parts to be used in the assembling work that has arrived from the parts box 13, thereby preventing mistakes in taking out the parts.

As described above, the production support method for preventing the mistake of picking up the components has been described. In addition to the production support method described above, the production support device 2 performs the production support for preventing the driver 5 from taking a mistake as described below. Implement the method. The production support method for preventing the driver 5 from making a mistake is performed in parallel with S3 and S4 after S0, S1 and S2 shown in FIG. 9 are performed. Further, after S0, S1, and S2 shown in FIG. 9 are performed, a production support method for preventing the driver 5 from making a mistake as described below may be performed without performing S3 and S4.

FIG. 15 is a flowchart showing the production support method of the present embodiment for preventing the driver 5 from making a mistake. In the process shown in FIG. 15, first, the production support apparatus 2 in S11, based on the work procedure information 21 that defines the order in which the plurality of drivers 5 are used, that is, the order in which power is supplied to the plurality of drivers 5. Power is supplied to one driver 5 of the plurality of drivers 5. The production support apparatus 2 can grasp the order in which the plurality of drivers 5 are used based on the order and tools in the work procedure information 21 shown in FIG. For example, in the work procedure information 21 shown in FIG. 14, the driver 5 corresponding to the Z ₁ identification information is used _first , the driver 5 corresponding to the Z ₂ identification information is used second, and the third. It shows that the driver 5 corresponding to the identification information of Z ₃ is used. If the driver 5 corresponding to the identification information of Z _i (i = 1, 2, 3,...) Is expressed as driver Z _i , in the example of the work procedure information 21 shown in FIG. The order of use is the order of driver Z ₁ , driver Z ₂ , driver Z ₃ ,.

Next, in S12, the production support apparatus 2 turns on the lamp 61 of one driver 5 to which power is supplied in S11, and visually displays that the one driver 5 is usable. As a result, the operator can use only the one driver 5, and mistakes in the driver 5 can be prevented.

The operator can perform screw tightening using the one driver 5 that can be used. At this time, as shown in S <b> 13, the production support apparatus 2 specifies the parts to be used in the assembly work based on the work procedure information 21 and makes only the specified parts usable. This process is the process of S3 and S4 in FIG. Thereby, the mistake of the screw removal by the operator is prevented.

Next, in S14, the production support apparatus 2 determines whether or not the one driver 5 has been operated. As a result of the determination in S14, when the one driver 5 operates, the production support apparatus 2 proceeds to the process of S15. If the result of determination in S14 is that the one driver 5 is not operating, the production support apparatus 2 returns to the processing in S14.

In S14, the production support apparatus 2 may perform a screw tightening pass / fail determination process based on the work content of the work procedure information 21 as well as whether or not the driver 5 has operated. The screw tightening pass / fail determination process will be described later, but if the screw tightening pass / fail determination process fails, the production support apparatus 2 performs a process of notifying the operator that the screw tightening is defective. , The process returns to S14. If the result of the screw tightening pass / fail determination process is acceptable, the production support apparatus 2 proceeds to the process of S15.

In S <b> 15, since the one driver 5 has operated in the production support apparatus 2, based on the work procedure information 21, the driver 5 whose order of use is the next order of the one driver 5, that is, the next driver 5. To supply power. In the work procedure information 21, the work order and the tool used for the work, that is, information indicating the driver 5 are associated with each other. Therefore, the work procedure information 21 is order information indicating the order in which power is supplied to the driver 5. is there. In S16, the production support device 2 lights the lamp 61 of the next driver 5 and visually displays that the next driver 5 is usable. As a result, the operator can use only the next driver 5 and mistakes in the driver 5 can be prevented.

The worker can execute screw tightening using the next available driver 5. At this time, as shown in S <b> 17, the production support apparatus 2 specifies the parts to be used in the assembly work based on the work procedure information 21 and makes only the specified parts usable. This process is the process of S3 and S4 in FIG.

The production support device 2 repeats the above process until all the drivers 5 are used. That is, after the next driver 5 operates, the production support apparatus 2 further supplies power to the next driver 5 based on the work procedure information 21 to make it usable.

15, the assembly work by the next driver 5 can be started before the assembly work by one driver 5 is completed. Accordingly, when a plurality of workers use the plurality of drivers 5 to perform assembly work, the next assembly work can be started before the previous assembly work is completed, so that the work time is shortened. .

In this embodiment, when the operation of one driver 5 is started, power is supplied to the next driver 5 during the operation of one driver 5.

FIG. 16 is a diagram illustrating an example of a temporal change in driving force supplied to the three

drivers

5a, 5b, and 5c. In FIG. 16, the upper part shows the time change Da of the driving force of the driver 5a, the middle part shows the time change Db of the driving force of the driver 5b, and the lower part shows the time change Dc of the driving force of the driver 5c. Da, Db, and Dc also indicate temporal changes in the power supplied to the

drivers

5a, 5b, and 5c, respectively.

As shown in FIG. 16, the driver 5a operates from time t1 to time t4. That is, the time t1 is the rotation start time of the driver 5a, and the time t4 is the rotation end time of the driver 5a. When the driver management unit 18 detects that the driver 5a starts rotating at time t1 based on the rotation start signal from the driver 5a, the driver management unit 18 supplies power to the driver 5b from time t2. Here, time t2 is a time after time t1 and before time t4. That is, when the operation of the driver 5a is started, the driver management unit 18 supplies power to the next driver 5b during the operation of the driver 5a. The driver 5b operates from time t2 to time t5. Here, time t5 is a time after time t4. Specifically, when the driver management unit 18 detects that the screw tightening by the driver 5a is completed by the torque-up signal from the driver 5a and the driver 5a has finished rotating at time t4, the driver management unit 18 sends the signal to the driver 5b at time t5. Shut off the power.

The driver management unit 18 supplies power to the driver 5c from time t3 when detecting that the driver 5b has started rotation at time t2 from the rotation start signal from the driver 5b. Here, time t3 is a time after time t2 and before time t5. That is, when the operation of the driver 5b is started, the driver management unit 18 supplies power to the next driver 5c during the operation of the driver 5b. The driver 5c operates from time t3 to time t6. Here, time t6 is a time after time t5. Specifically, when the driver management unit 18 detects that the screw tightening by the driver 5b is completed by the torque-up signal from the driver 5b and the driver 5b has finished rotating at time t5, the driver management unit 18 sends the signal to the driver 5c at time t6. Shut off the power.

Next, the screen displayed on the display 3 when the worker is performing the assembly work will be described. That is, the screen displayed on the display device 3 during execution of S3 and S4 in the flowchart described in FIG. 9 and during execution of the flowchart shown in FIG. 15 will be described. FIG. 17 is a diagram illustrating an example of an assembly work instruction screen displayed on the display 3 during the assembly work. The display screen 31 that is an assembly work instruction screen is displayed when, for example, the home button is touched in the menu shown in FIG. Therefore, after S2 in the flowchart described with reference to FIG. 9, when the operator touches the home button on the menu, an assembly work instruction screen is displayed. Specifically, the display screen 31 visualizes the assembly work and is a screen showing an assembly work instruction. The display screen 31 includes an image 44 of a product whose “model name” is “PA2300”. Screw fastening locations 31a to 31d are locations where four screws are fastened. The numbers shown in the screw tightening locations 31a to 31d indicate the order of screw tightening. The order of screw tightening is the order in the work procedure information 21. The numbers indicating the order of screw tightening are not displayed when the corresponding screw tightening is completed. FIG. 17 shows a state where the screw tightening of any of the screw tightening points 31a to 31d is not completed. Thereafter, for example, the number of the screw tightening portion 31a that is the first screw tightening portion is not displayed when the screw tightening of the first screw tightening portion is completed. That is, the assembly work instruction screen, which is a display screen on which work procedures are displayed, is switched according to the progress of the assembly work. The progress of the assembly work indicates whether each work, that is, each assembly work is completed. This switching may be switching as to whether or not numbers are displayed in the screw tightening locations 31a to 31d as described above, or may be switching based on a color difference between the screw tightening locations 31a to 31d. When switching according to the color difference between the screw tightening locations 31a to 31d, the screw tightening locations 31a to 31d are displayed in different colors depending on whether the corresponding operation is completed or not.

In addition, the display screen 31 shows that “production unit” is “100”, “production completion” is “24”, “screw tightening” is “6” in total, and screw tightening is rejected. “NG (defective) number” is displayed as “0”. In addition, a “driver” indicating the type “M5” of the driver 5, a “screw type” indicating the type of screw, a “screw size” indicating the screw size “M5 × 20”, and the number of screws used in the assembly work “Number” indicating “4” is shown.

Furthermore, the display screen 31 shows a lower limit value “1” seconds and an upper limit value “4” seconds of the “screw tightening time” that is the rotation time of the driver 5. In S14 described with reference to FIG. 15, when the screw tightening pass / fail determination process is performed, the pass / fail determination unit 19 determines that the “screw tightening time” is not included in the range of the upper and lower limit values. Is determined to be rejected, that is, defective. The range of the upper and lower limit values is registered in advance as the time required for normal screw tightening in the input of work content using the work content input screen 110 shown in FIG. The range of the upper and lower limit values is the rotation time range described above. When performing screw tightening pass / fail judgment processing based on the number of rotations, the input of work details accepts the input of the upper and lower limits of the number of rotations instead of the upper and lower limits of the “screw tightening time” that is the rotation time. It is done.

“30 seconds”, which is “standard work time”, is an average value of work time. “Measured value” is the actual work time. The work time is a time required for an assembly work including a plurality of screw tightenings. The “standard work time” can be used as a pacemaker for the worker.

In addition, when “actual value” is larger than “standard work time”, when “actual value” is more than half of “standard work time” and less than “standard work time”, and “actual value” is “standard work time” The color of the numerical value of “actually measured value” can be made different from the case of less than half of “”. As a result, the work speed can be easily recognized.

Furthermore, the “use parts”, “assembly message”, and “caution points” are described on the display screen 31, and specific instructions at the time of screw tightening and parts attachment are displayed.

¡Work mistakes are suppressed when the worker works while referring to the assembly work instructions as described above. Therefore, even a new worker can learn the work in a short period of time, and the man-hour required for new employee education can be reduced.

Note that the display screen 31 corresponds to a plurality of modes according to the skill level of the operator. That is, the display screen 31 can be switched between a standard mode screen for a standard worker and a skilled mode screen for an expert. The skill mode screen is devised to shorten the tact time as compared to the standard mode screen. For example, in the standard mode screen, the operator needs to update the screen by touching the screen when moving to the next work after the work is completed, but in the expert mode screen, the operator touches the screen. The screen is automatically updated at regular time intervals without need.

FIG. 18 is a diagram illustrating an example of a display screen of the display 3 when the screw tightening pass / fail determination process fails. As described above, the production support device 2 notifies the operator of the determination result when determining whether or not the screw tightening is successful in S14. On the display screen 32 shown in FIG. 18, a warning message “Screw tightening NG” and a “Confirm” button are displayed, indicating that a failure has occurred in screw tightening. Further, the occurrence of a defect in the screw tightening location 31a is displayed by making the background color of the screw tightening location 31a different from the background color of the screw tightening locations 31b to 31d.

The production support apparatus 2 can notify the operator of the screw tightening determination result by the screen display of the buzzer 7, the indicator lamp 8, and the display 3. This prevents the work from proceeding to the subsequent process in a state where there is a defective portion in screw tightening.

Further, the production support apparatus 2 performs scheduling of the work process using the measured value of the work time required for the screw tightening work in the assembly work, and uses the measured value to set the normal upper and lower limit values in the pass / fail judgment process. The value in the range may be corrected. FIG. 19 is a diagram illustrating an example of a display screen for measuring the work time required for the screw tightening work. The display screen 33 shown in FIG. 19 is displayed, for example, by touching a torque check button in the menu column. On the display screen 33, the “measured value” of the work time required for the screw tightening work is shown. In the example shown in FIG. 19, the “measurement value” is “12345” milliseconds. The “actual measurement value” shown in FIG. 19 is displayed as “12” seconds by rounding off the first decimal place with “12345” milliseconds expressed in seconds. The operator can register “measured value” in the production support apparatus 2 by pressing “register” on the display screen 33.

Measured values can be used to set the rotation time range for determining whether screw tightening is successful or not. That is, the production support apparatus 2 can obtain an average value based on the measured value, and can set a certain range including the average value as the rotation time range. Thereby, the rotation time range along the actual work can be used for the screw tightening determination, and the screw tightening determination can be performed more appropriately. The rotation time range can also be set manually by the operator. Further, the measurement value may be used for scheduling the work process.

FIG. 20 is a graph showing an example of the defect occurrence rate by model and by worker. The horizontal axis indicates models A to G, and the vertical axis indicates the defect occurrence rate. The defect occurrence rate is displayed separately for skilled and unskilled persons. Such a graph shows which model is likely to cause screw tightening defects.

Also, by replacing the model with work items, it is easy to identify which work items are likely to cause screw tightening defects, which work items are time-consuming, and which are likely to cause problems. It becomes possible. Here, the work item is a unit of work procedure.

For example, it can be seen which of the screws that are likely to fail when tightening five screws. From this, it is possible to examine whether it is a design problem that a defective portion is likely to occur or whether it is improved by using a jig.

In this way, by displaying the graph shown in FIG. 20, it is possible to realize a specific approach for reviewing the system design, reexamining and improving work items.

Note that the graph shown in FIG. 20 can be displayed on the display unit 3 or can be displayed on the display unit of the management server 11. The management server 11 can collect and display work history information obtained from the plurality of production support apparatuses 2. Thereby, when adjustment of the number of workers by the increase / decrease of the number of production is required, the information at the time of dividing or combining the processes shared by the workers can be obtained.
