Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a remote operation system 1 in one embodiment of the present invention. The remote operation system 1 includes a plurality of work devices 2, a management device 3, and a plurality of remote monitoring devices 4. Each work device 2 and the management device 3 and each remote monitoring device 4 and the management device 3 are connected by wire or wirelessly so that they can communicate with each other. Each remote monitoring device 4 is operated by an operator OP placed corresponding to each remote monitoring device 4.

In this embodiment, each work device 2 is composed of a component mounting device that performs work (component mounting work) to mount the component BH onto the board KB. As shown in FIG. 3, the working device 2 includes a base 11, a conveyor 12, a tape feeder 13, a head moving mechanism 14, a mounting head 15, and a substrate camera 16.

In FIG. 3, the conveyor 12 extends horizontally on the base 11, and conveys the substrate KB horizontally from one end to the other end. The tape feeder 13 uses a built-in sprocket 13S (see also FIG. 4) to pull out and convey the carrier tape CT wound around the reel RL.

A large number of parts BH are enclosed in a line in a line in the carrier tape CT. The tape feeder 13 feeds the component BH to the component supply position 13K by feeding the carrier tape CT toward the transport conveyor 12 (FIGS. 3 and 4).

The head moving mechanism 14 includes, for example, an XY table mechanism, and moves the mounting head 15 within a horizontal plane. The mounting head 15 includes a plurality of nozzles 15N extending downward (FIGS. 3 and 4).

In FIGS. 3 and 4, the board camera 16 is attached to the mounting head 15 with its imaging optical axis facing downward. The board camera 16 is moved in the horizontal plane together with the mounting head 15 by the head moving mechanism 14 .

The operations of each part of each work device 2, that is, the conveyor 12, tape feeder 13, head moving mechanism 14, mounting head 15, and board camera 16, are controlled by the work device control section 17 (FIG. 3), which is the control section thereof. (Figure 5). Thereby, the transport conveyor 12 transports and positions the board KB, and each tape feeder 13 supplies the component BH to the component supply position 13K. The head moving mechanism 14 moves the mounting head 15, and the mounting head 15 sucks the component BH with the nozzle 15N (FIG. 4). The board camera 16 performs an imaging operation based on a command from the work equipment control section 17. Image data obtained by the imaging operation of the board camera 16 is sent to the work equipment control section 17 and processed.

When the work device 2 performs the component mounting work, first, the conveyor 12 is operated to carry in the board KB and position it at the work position. When the board KB is positioned at the working position, the head moving mechanism 14 is activated to move the mounting head 15 above the board KB, and the board camera 16 is caused to take an image of the board KB. When the board camera 16 images the board KB, the board KB is recognized based on the image.

After recognizing the board KB, the work device 2 causes the tape feeder 13 to supply the component BH, and causes the mounting head 15 to perform a component pickup operation and a component mounting operation. In the component pickup operation, the mounting head 15 adsorbs (picks up) the component BH supplied by the tape feeder 13 with the nozzle 15N, and in the component mounting operation, mounts the picked-up component BH at a predetermined position on the board KB.

After the work device 2 has mounted all the parts BH to be mounted on the board KB by repeatedly performing a component pickup operation and a component mounting operation on the mounting head 15, the work device 2 operates the conveyor 12 to carry out the board KB from the working position. . This completes the component mounting work for each board KB.

Although the work device 2 executes the component mounting work according to the above-described procedure, some kind of error may occur during the process. In the remote operation system 1 according to the present embodiment, when an error occurs in the working device 2, the error can be resolved by remote operation from the remote monitoring device 4. I do.

In FIG. 5, the work equipment control section 17 includes an error detection section 21, an error information acquisition section 22, an error information transmission section 23, and a resolution operation information reception section 24. The error detection unit 21 detects any error that occurs in the working device 2 and interrupts the operation of all or part of the working device 2. The error information acquisition unit 22 identifies the location where the error detected by the error detection unit 21 has occurred (error occurrence location), and acquires information on the error (type and its content) that has occurred as “error information”.

If the error occurrence location can be imaged by the board camera 16, the error information acquisition unit 22 operates the head moving mechanism 14 to move the board camera 16 above the error occurrence location, and moves the error occurrence location to the board. The camera 16 is made to take an image. For example, if the mounting head 15 fails to pick up a component BH from a certain tape feeder 13 a certain number of times in a row, the component supply position 13K of that tape feeder 13 is identified as the error occurrence location, and the component The substrate camera 16 is caused to take a still image or a moving image of the supply position 13K.

The error information transmitter 23 transmits the error information acquired by the error information acquirer 22 to the management device 3 (FIG. 2). When the error occurrence location is imaged by the board camera 16, image data (still image or video data) of the error occurrence location is transmitted to the management device 3 as part of the error information.

In FIG. 5, the management device 3 includes a skill database 31, a storage section 32, a destination selection section 33, and a response instruction transmission section 34. An administrator input device 35 is connected to the management device 3 .

The skill database 31 records skill data of each of a plurality of operators OP who operate a plurality of remote monitoring devices 4. The skill data of each operator OP includes data on the work performance of that operator OP (for example, the number of successful error resolutions and their success rate, the time required to process one error, the types of errors that can be handled, etc.). There is. When the operator OP performs processing for an error, the performance including the success or failure of the error processing is recorded in the skill database as part of the operator's work performance.

The storage unit 32 stores priority information of the remote monitoring device 4 to which an instruction to deal with an error occurring in the work device 2 can be sent. Here, the term "response instruction" refers to an instruction for responding to an error that has occurred. Moreover, "priority information" refers to information indicating in what order the response instructions for errors occurring in the work device 2 are to be transmitted.

When an error occurs in the work equipment 2, the destination selection unit 33 issues response instructions based on the priority information stored in the storage unit 32 or the skill data of each operator OP recorded in the skill database 31. Select the remote monitoring device 4 to be the destination. The response instruction transmitting unit 34 transmits the response instruction to the remote monitoring device 4 selected by the destination selection unit 33.

In this embodiment, the combination of each remote monitoring device 4 and the operator OP who operates it is not fixed. Therefore, each operator OP can operate from any remote monitoring device 4, but before operating the remote monitoring device 4, the operator OP must check his own identifier and the identifier of the remote monitoring device 4 that he operates. The combination is reported to the management device 3. Therefore, the management device 3 always knows which remote monitoring device 4 is being operated by which operator OP, and sending the destination of response instructions to the remote monitoring device 4 means that the remote monitoring device 4 is operated by the remote monitoring device 4. means to send it to the operator OP who

In FIG. 5, the administrator input device 35 includes an input operation section 36 and a display 37. The input operation unit 36 functions as a priority input unit that inputs the priority of the remote monitoring device 4 to be set and stores the input data (priority information) in the storage unit 32.

The administrator of the management device 3 can display, for example, a mode selection screen as shown in FIG. 6 on the display 37 by performing a predetermined operation from the input operation section 36 of the administrator input device 35. As shown in FIG. 6, this mode selection screen is provided with a mode selection area R1. “Mode selection area R1” is a mode (“first mode”) in which the destination selection unit 33 selects the remote monitoring device 4 to which the response instruction is transmitted based on the priority information stored in the storage unit 32. ) and a mode in which the destination selection unit 33 selects the destination of the response instruction based on the skill data of the operator OP recorded in the skill database 31 (referred to as the "second mode"). It is an area for When the administrator selects either the first mode or the second mode from the mode selection area R1 and operates the confirm button BT1, information on the selected mode (whether the selected mode is the first mode or the second mode is selected) is displayed. 2 mode) is sent to the management device 3 and stored in the storage unit 32.

As described above, in the present embodiment, the input operation unit 36 allows the destination selection unit 33 to select the remote monitoring device 4 to which the response instruction is to be transmitted based on the priority information stored in the storage unit 32. 1 mode and a second mode in which the destination selection unit 33 selects the destination of the response instruction based on the skill data of the operator OP recorded in the skill database 31. .

FIG. 7 shows an example of a priority setting screen displayed on the display 37 of the administrator input device 35. In the example shown here, in what order should the three operators OP (OPA, OPB, OPC) who operate the three remote monitoring devices 4 perform processing for an error that has occurred in the work device 2? It is now possible to allocate it to each error type (type "1", type "2", . . . ). The priority order setting screen shown in FIG. 7 can be displayed by performing a predetermined operation from the input operation section 36 after selecting the first mode on the mode selection screen shown in FIG.

In the example shown in FIG. 7, the error type can be selected from a plurality of tabs TAB (type "1", type "2", . . . ). The priority order is specified by entering the numbers "1", "2", etc. in the priority entry field corresponding to each operator OP (OPA, OPB, OPC) in the order entry box BX1 shown in the figure. can do. Also, for the timing at which the priority changes from high to low, that is, the waiting time until moving to the next operator OP, enter the time (for example, seconds as shown in the figure) in numbers in the time input box BX2 shown in the figure. It can be specified by

In addition, in the example shown in FIG. 7, when the operator OP with the lowest priority, that is, the last operator OP, does not respond as a result of calling that operator OP, the operator OP with the highest priority (first priority) is called. ) to return to the operator OP and send a response signal again, or to notify the administrator of the management device 3 and end the error handling without returning (second round processing procedure) in the procedure selection area R2. You can choose from. When the administrator finally operates the setting button BT2, the contents entered on the priority setting screen are finalized, and the contents are sent to the management device 3 and stored in the storage section 32.

As described above, in this embodiment, the administrator input device 35 serves as a priority input means for inputting a priority and storing it in the storage unit 32.

When an error occurs in the work device 2 and error information is sent from the work device 2, the management device 3 controls the remote monitoring device 4 (to which the response instructions are sent) when the first mode is selected. An operator OP) is selected based on the priority information stored in the storage unit 32, and a response instruction is transmitted to the selected remote monitoring device 4 (operator OP). On the other hand, when the second mode is selected, the remote monitoring device 4 (operator OP) to which the response instruction is sent is selected based on the skill data of each operator OP recorded in the skill database 31, and the selected A response instruction is sent to the remote monitoring device 4 (operator OP).

In FIG. 1, each of the plurality of remote monitoring devices 4 is composed of, for example, a personal computer. As shown in FIG. 5, each remote monitoring device 4 includes a remote monitoring control section 41, a monitor 42, and an input device 43.

In FIG. 5, the remote monitoring control unit 41 includes a response instruction receiving unit 51, an error information display control unit 52, and a resolution operation information transmitting unit 53. The response instruction receiving unit 51 receives the response instruction sent from the management device 3, and the error information display control unit 52 displays error information, which is the specific content of the response instruction received by the response instruction receiving unit 51, on the monitor 42. Display.

FIG. 8A shows an image GZ of an error occurrence location as an example of error information displayed on the monitor 42 by the error information display control unit 52. The image GZ shown in FIG. 8(a) shows the area including the component supply position 13K of the tape feeder 13 when the above-described suction error of the component BH occurs, and the center position of the image GZ where the error occurs coincides with the position of the lower end of the nozzle 15N (nozzle lower end position KC). When the image GZ of the error occurrence location is displayed on the monitor 42, the operator OP performs an operation to eliminate the error from the input device 43 while viewing the image GZ.

The nozzle lower end position KC should originally match the component supply position 13K, but in the image GZ of FIG. 8(a) in which an error has occurred, the nozzle lower end position KC and the component supply position 13K do not match. Not yet. In this case, the operator OP performs an operation to move the position of the mounting head 15 during component suction so that the nozzle lower end position KC matches the component supply position 13K of the tape feeder 13. Specifically, the mounting head 15 is adjusted during component suction so that the difference between the nozzle lower end position KC and the component supply position 13K in the image GZ of FIG. 8(a) is canceled and the state shown in FIG. 8(b) is obtained. An offset amount (moving direction and moving amount) for moving the position is input from the input device 43.

The resolution operation information transmitting unit 53 transmits information on the error resolution operation (resolution operation information) input from the input device 43 to the management device 3 . When the management device 3 receives the cancellation operation information, it transmits (transfers) the received cancellation operation information to the work device 2 that is the source of the error information (FIG. 2).

The work device 2 to which the cancellation operation information has been transmitted (transferred) from the management device 3 (the work device 2 that has transmitted the error information to the management device 3) receives the cancellation operation information by the cancellation operation information receiving unit 24. The work device control unit 17 of the work device 2 that has received the resolving operation information eliminates the error by operating a portion related to the location where the error has occurred based on the received resolving operation information.

In this embodiment, when the operator OP performs an error resolution operation from the remote monitoring device 4 that has received a response instruction from the management device 3, the work device 2 is remotely controlled through the management device 3. The error that occurred in 2 has been resolved. When the error is resolved, the work device control unit 17 cancels the suspended state of the component mounting work and restarts the component mounting work.

In this way, in the remote operation system 1 according to the present embodiment, when an error occurs in the work device 2, the management device 3 causes the remote monitoring device 4 selected from a plurality of remote monitoring devices 4 to respond to the error. When the operator OP performs an operation to resolve the error from the remote monitoring device 4 that has received the response instruction, the work device 2 is remotely controlled through the management device 3 and the error occurs in the work device 2. The error is now resolved. The storage unit 32 of the management device 3 stores priority information of the remote monitoring device 4 that can be the destination of a response instruction for an error that occurs in the work device 2, and the destination selection unit 33 In this case, the remote monitoring device 4 to which the response instruction is to be sent is selected based on the priority information stored in the storage unit 32, or based on the skill data of each operator OP recorded in the skill database. Then, the remote monitoring device 4 to which the response instruction will be sent is selected. Therefore, according to the remote operation system 1 according to the present embodiment, it is possible to efficiently resolve an error occurring in the work device 2 without necessarily relying on the skill data of the operator OP.

Note that in the second mode, the administrator can preset how the destination selection unit 33 selects the remote monitoring device 4 based on the skill data of each operator OP. Therefore, for example, it is possible to preferentially select the remote monitoring device 4 operated by the operator OP who has a small amount of work (or work time) within a certain period of time as the destination of the response instruction.

FIG. 9 is a flowchart showing the flow of processing in which the destination selection unit 33 transmits a response instruction to the remote monitoring device 4 when the first mode is set in the remote operation system 1 according to the present embodiment. .

When the first mode is set, when error information is sent from the work device 2 to the management device 3, the destination selection unit 33 first recognizes the type of error (step ST1). Then, after setting the priority N to the highest level "1" (N=1) (step ST2), the remote monitoring device 4 with the priority N is set as the destination of the response instruction; The operator OP of the remote monitoring device 4 is called (step ST3).

After reading the operator OP of the remote monitoring device 4 with priority N, it is determined whether there is a response from the operator OP (step ST4). Then, if there is a response from the operator OP, a response instruction (specifically, error information) is sent to the remote monitoring device 4 operated by the operator OP (step ST5), and if there is no response, the set It is checked whether the waiting time has elapsed (step ST6). If the waiting time has not elapsed, the process returns to step ST3 to continue calling the operator OP, and if the waiting time has elapsed, a response instruction is sent to the remote monitoring device 4 with the next highest priority N. In order to do so, "1" is added to the value of the priority order N (N=N+1) to update the value of the priority order N (step ST7).

After updating the value of priority N, check whether the updated value of priority N corresponds to the lowest priority N (=Max) (here, there are three operator OPs, so Max = 3). is checked (step ST8). If the value of the updated priority N is not a value corresponding to the lowest priority N, the process returns to step ST3, calls the operator OP of the remote monitoring device 4 corresponding to the updated priority N, and If the updated value of priority N is a value corresponding to the lowest priority N, the priority N returns to the remote monitoring device 4 whose priority is the highest (N=1) and sends a response instruction. It is determined whether or not (step ST9). As a result, if it is determined to return to the remote monitoring device 4 with the highest priority N, the process returns to step ST2, and if it is determined not to return, the administrator is notified (step ST10) and the process ends. do.

As explained above, the remote operation system 1 in this embodiment instructs the remote monitoring device 4 selected from the plurality of remote monitoring devices 4 to respond to the error when an error occurs in the working device 2. The management device 3 is equipped with a management device 3 that transmits a response instruction, and the management device 3 stores priority information of a remote monitoring device 4 to which a response instruction for an error occurring in the work device 2 can be transmitted. , When an error occurs in the work device 2, the remote monitoring device 4 to which the response instruction is to be sent is selected based on the stored priority information, and the response instruction is sent to the selected remote monitoring device 4. (if the first mode is set). Therefore, in the remote operation system 1 according to the present embodiment, the administrator who manages the management device 3 sets priorities based on his own policy and stores them in the management device 3 (specifically, in the storage unit 32). By doing so, it is possible to efficiently resolve an error occurring in the work device 2 without relying on the skill data of the operator OP.

Further, the remote operation system 1 in this embodiment includes a skill database 31 in which skill data of each of a plurality of operator OPs who operate a plurality of remote monitoring devices 4 is recorded, and is based on stored priority order information. one of the first mode in which the remote monitoring device 4 to which the response instruction will be sent is selected based on the skill data of the operator OP recorded in the skill database 31; and the second mode in which the destination to which the response instruction is sent is selected based on the skill data of the operator OP recorded in the skill database 31. You can now choose. Therefore, the destination of the response instruction can be selected based on the skill of the operator OP (if the second mode is set). Error resolution processing work can be performed extremely efficiently compared to the above.

Although the embodiments of the present invention have been described so far, the present invention is not limited to the above-described embodiments, and various modifications and the like are possible. For example, in the above-described embodiment, a component mounting device is shown as an example of the working device 2, but the working device 2 may be a working device other than the component mounting device.

To provide a remote operation system that can efficiently perform processing work to resolve errors occurring in a working device.
