BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a remote control system 1 according to one embodiment of the invention. A remote operation system 1 includes a work line 2 , a server 3 and a plurality of remote monitoring units 4 . In this embodiment, the work line 2 is formed by arranging in series a plurality of component mounters 2A, which are work devices for mounting components on the board KB.

First, the component mounting apparatus 2A will be described. The component mounting apparatus 2A includes a base 11, a conveyor 12, a tape feeder 13, a head moving mechanism 14, a mounting head 15, a board camera 16 and a component camera 17, as shown in FIG. The transport conveyor 12 extends horizontally on the base 11 and transports the substrate KB horizontally from one end to the other end.

The tape feeder 13 draws out and conveys the carrier tape CT wound around the reel RL by a built-in sprocket 13S (see also FIG. 3). A large number of components are enclosed in a row on the carrier tape CT. The tape feeder 13 intermittently feeds the carrier tape CT toward the end of the conveyor 12, thereby continuously supplying the components BH to the predetermined component supply position 13K.

The head moving mechanism 14 is composed of, for example, an XY table mechanism, and moves the mounting head 15 within a horizontal plane. The mounting head 15 has a plurality of nozzles 15N extending downward in the vertical direction. The mounting head 15 can adsorb the component BH supplied by the tape feeder 13 to the lower end of each nozzle 15N (see also FIG. 3).

2 and 3, the substrate camera 16 is attached to the mounting head 15 with the imaging optical axis directed downward. The board camera 16 moves in the horizontal plane together with the mounting head 15 .

In FIG. 2, the component camera 17 is attached to the base 11 with the imaging optical axis directed upward. The component camera 17 images the component BH from below when the mounting head 15 picking up the component BH moves above the board KB.

A mounting apparatus control section 18 (FIG. 2), which is a control section of the component mounting apparatus 2A, controls the operation of each section of the component mounting apparatus 2A (FIG. 4). Specifically, the mounting device control unit 18 controls the transport operation of the board KB by the transport conveyor 12 and controls the supply operation of the component BH to the component supply position 13K by each tape feeder 13 . Further, the mounting apparatus control section 18 controls the movement of the mounting head 15 by the head moving mechanism 14, and controls the movement of the mounting head 15 to pick up the component BH by the nozzle 15N. The mounting device control unit 18 also controls the imaging operation of the board camera 16 and controls the imaging operation of the component camera 17 . The image data obtained by imaging by the board camera 16 and the image data obtained by imaging by the component camera 17 are sent to the mounting apparatus control section 18, respectively.

When the component mounting apparatus 2A performs the work of mounting the component BH on the board KB (component mounting work), first, the board KB is carried in by the transport conveyor 12 and positioned at the work position. When the board KB is positioned at the working position, the mounting head 15 is moved above the board KB, and the board camera 16 takes an image of the board KB. The mounting apparatus control unit 18 recognizes the board KB based on image data obtained by imaging the board KB with the board camera 16 .

When the component mounting apparatus 2A recognizes the board KB, the tape feeder 13 continuously supplies the components BH to the component supply position 13K, and the mounting head 15 moves between the tape feeder 13 and the board KB. Executes wearing turns repeatedly. The mounting turn of the mounting head 15 consists of the operation of sucking the component BH supplied by the tape feeder 13 with the nozzle 15N, and the route in which the sucked component BH passes through the upper area of the component camera 17 (image field of view of the component camera 17). It consists of an operation of moving above the KB and an operation of mounting the component BH on the board KB from above the board KB.

The component camera 17 captures an image of the component BH from below when the component BH passes through the imaging field of view. to recognize The recognition result of the component BH and the recognition result of the board KB are used for position correction of the nozzle 15N when the mounting head 15 mounts the component BH on the board KB.

When the mounting head 15 repeats the mounting turn and all necessary parts BH are mounted on the board KB, the transport conveyor 12 carries out the board KB from the work position. Then, the transport conveyor 12 newly carries in the next board KB.

The component mounting apparatus 2A performs the component mounting work according to the above-described procedure, but some kind of error may occur in the process. If any error occurs, the component mounting apparatus 2A suspends all or part of the component mounting work and enters an error resolution mode. Then, the location where the error occurs (error occurrence location) is specified, the board camera 16 is moved above the specified error occurrence location, and the board camera 16 is made to image the error occurrence location. For example, when the mounting head 15 continuously fails to pick up the component BH from a certain tape feeder 13, the component supply position 13K of the tape feeder 13 is identified as the error occurrence location, and the error occurrence location is determined. is imaged by the board camera 16 . At this time, the substrate camera 16 captures a still image of the error occurrence location, or captures a moving image in real time.

The mounting device control unit 18 of the component mounting device 2A in which the error has occurred takes an image of the error occurrence location with the board camera 16, and transmits the obtained image data to the server 3 as error information (FIG. 4). The error information (image data) transmitted from the mounting device control unit 18 to the server 3 at this time is still image data or moving image data of the error occurrence location.

In FIG. 4, the server 3 is connected to each of a plurality of component mounting apparatuses 2A constituting the work line 2 by wire or wirelessly. The server 3 receives the error information (image data of the error occurrence location) transmitted from the component mounting apparatus 2A in which the error has occurred.

In FIG. 4 , the server 3 has a storage section 31 , a selection section 32 and a transfer section 33 . In the storage unit 31 of the server 3, various data are stored in advance, and various information such as error information transmitted from the component mounting apparatus 2A is stored at any time.

The selection unit 32 of the server 3 selects one remote monitoring unit 4 as a transfer destination of the error information transmitted from the component mounting apparatus 2A in which the error has occurred. The transfer unit 33 of the server 3 transfers the error information to one remote monitoring unit 4 selected by the selection unit 32 (FIG. 4).

1 and 4, the remote monitoring unit 4 is composed of, for example, a personal computer, and is connected to the server 3 by wire or wirelessly. Each remote monitoring section 4 comprises a remote monitoring control section 41, a display device 42 and an input device 43, and the remote monitoring control section 41 comprises a receiving section 41a and a transmitting section 41b. One operator is permanently stationed in each of the plurality of remote monitoring units 4 .

When the receiving unit 41a receives the error information transferred from the server 3, the remote monitoring unit 4 causes the error information image (still image or moving image) to be displayed on the error resolution operation screen 51 (FIG. 4). This error resolution operation screen 51 can be displayed on the display device 42 by the operator operating the input device 43 .

When the image of the error occurrence location is displayed on the error resolution operation screen 51 of the display device 42 (if it is a moving image, the display starts), the operator looks at the image displayed on the display device 42 and inputs the error from the input device 43. Perform an input operation to resolve the error (error resolution operation). When the operator performs an error elimination operation from the input device 43, the error elimination operation signal (elimination operation signal) is transmitted to the server 3 through the transmission section 41b (FIG. 4).

FIG. 5A shows an example of an error resolution operation screen 51 displayed on the display device 42, which is an image (still image or moving image) obtained by imaging the error occurrence location with the board camera 16. FIG. Here, an example of an image of an area including the component supply position 13K of the tape feeder 13 when the above-described component BH pick-up error occurs is shown. KC).

Originally, the nozzle bottom end position KC should coincide with the component supply position 13K (FIG. 5(b)), but when an error occurs, as shown in FIG. It is considered that the part BH was picked up incorrectly because it did not match the part supply position 13K. In this case, the error elimination operation performed by the operator from the remote monitoring unit 4 is an operation of moving the position of the mounting head 15 during component pickup so that the nozzle lower end position KC coincides with the component supply position 13K of the tape feeder 13. . Specifically, an offset amount (movement direction and amount of movement).

When the server 3 receives a clearing operation signal from the remote monitoring unit 4 (FIG. 4), the server 3 relays the clearing operation signal to the component mounting apparatus 2A in which the error has occurred (FIG. 4). The mounting apparatus control section 18 of the component mounting apparatus 2A that has thus received the clearing operation signal relayed by the server 3 operates according to the received error clearing operation. When the error is resolved as a result, the mounting device control unit 18 assumes that the error has been recovered and restarts the component mounting work. FIG. 5(b) shows an image of an error occurrence location in a state where the error in the image of FIG. 5(a) has been eliminated by the error elimination operation performed by the remote monitoring unit 4. .

As described above, the remote operation system 1 according to the present embodiment includes the work line 2, the server 3, and a plurality of remote monitoring units 4, and can information is transferred to one of the plurality of remote monitoring units 4 via the server 3, and the operator of the remote monitoring unit 4 who receives the transfer of the error information performs an operation via the server 3 to eliminate the error. , an error occurring in the work line 2 (component mounting apparatus 2A) can be resolved by remote operation from the remote monitoring unit 4. FIG.

By the way, in the remote operation system 1 according to the present embodiment, since the error information is sent to the remote monitoring unit 4 when the operator is away from his post (that is, is away from the remote monitoring unit 4 in charge), the operator It is designed to prevent a situation in which the error processing work does not proceed until the worker returns to his/her station. In addition, it is possible to prevent a situation in which an operator is requested to perform error processing of a type with low processing skill and takes a lot of time to eliminate the error. A configuration for exhibiting such functions of the remote operation system 1 will be described below.

In the remote operation system 1 according to this embodiment, when the operator performs a predetermined operation from the input device 43 of the remote monitoring section 4, an operator self-setting screen 52 as shown in FIG. The upper part of this operator self-setting screen 52 is a presence status setting part 53, and the lower part of the operator self-setting screen 52 is a availability setting part 54 (see also FIG. 4).

In FIG. 6 , the presence status setting section 53 has a presence button 61 and an absence button 62 . The presence status setting section 53 is a section for the operator to set whether the remote monitoring section 4 in charge of the operator is in the presence state or in the absence state as the presence status.

The operator can operate the presence button 61 and the leave button 62 on the operator self-setting screen 52 at any time while he/she is at his/her own post, that is, while he/she is at the remote monitoring section 4 in charge. The presence button 61 and the leaving button 62 can be operated alternatively, and the one operated most recently by the operator lights up and the other goes out.

When the operator is at his/her own post, the presence button 61 is turned on (the leave button 62 is turned off). The seat button 61 is turned off). Then, after leaving the post by operating the leaving button 62, when returning to the post, the presence button 61 is operated so that the presence button 61 lights up. FIG. 6 shows a state in which the operator has operated the presence button 61 most recently, so the presence button 61 is lit and the leaving button 62 is unlit. It should be noted that the operation of the leave button 62 is performed while the operator is at the remote monitoring unit 4 in charge. Of course, it is not the state.

When the operator operates the presence button 61 , “presence information” is transmitted to the server 3 through the transmission section 41 b of the remote monitoring section 4 . On the other hand, when the operator operates the leave button 62, "seat leave information" is transmitted to the server 3 through the transmission unit 41b. If the server 3 determines that the most recently transmitted information among the presence information and the absence information transmitted from each remote monitoring unit 4 is the presence information, the operator is assigned to his/her assigned position (the remote monitoring unit 4 in charge is present). If the most recently transmitted information is out-of-seat information, it is determined that the operator is away from his/her post (leaving the remote monitoring section 4 in charge).

In FIG. 6, the response availability setting unit 54 includes a response availability button 63 and a response failure button 64 for each error type (here, "A", "B", and "C"). This response propriety setting section 54 is a portion in which the operator in charge of the remote monitoring section 4 sets the propriety of handling for each type of error by himself/herself. Here, as the types of errors, for example, as described above, in addition to failure in picking up the component BH by the mounting head 15, failure in recognizing the substrate KB through the substrate camera 16, failure in recognizing the component BH through the component camera 17, etc. etc.

While the operator is in his/her own post, i.e., while he/she is present at the remote monitoring unit 4 in charge, the operator can operate the response enable button 63 and the response disable button 64 for each error type on the operator self-setting screen 52 at any time. Yes (but usually only once when the operator arrives at his station). The corresponding button 63 and the non-corresponding button 64 can be selectively operated for one error type, and the one operated most recently by the operator lights up and the other goes out.

The operator turns on the responsive button 63 (turns off the unresponsive button 64) for the types of errors that the operator determines to be capable of handling, and responds to the types of errors that the operator determines to be unresponsive. The disable button 64 is turned on (the correspondence enable button 63 is turned off). When the operator determines that the type of error cannot be dealt with, it means that the error cannot be processed at all, or that the error can be processed but obviously takes a lot of time. FIG. 6 shows a state in which the operator has operated the available button 63 for types "A" and "C" and has operated the unavailable button 64 for type "B".

When the operator operates the response available button 63 for a certain error type, the "response available information" is transmitted to the server 3 through the transmission section 41b of the remote monitoring section 4. FIG. On the other hand, when the operator operates the non-handling button 64 for a certain error type, "non-handling information" is transmitted to the server 3 through the transmission unit 41b. The server 3 can handle the type of error if the most recently transmitted one of the available information and the unavailable information for each type of error sent from each remote monitoring unit 4 is the available information. If the most recently transmitted information is unsupportable information, the operator determines that the type of error cannot be supported.

The server 3 establishes a correspondence relationship between each of the plurality of remote monitoring units 4 and the presence status set by the operator in charge of each of the plurality of remote monitoring units 4 (more specifically, the presence status transmitted from each remote monitoring unit 4). Presence status information that is a correspondence relationship in which the most recently transmitted one of information and absence information is associated with the remote monitoring part 4 is created, and the created presence status information is stored in a storage part 31. - 特許庁. In addition, the server 3 establishes a correspondence relationship between each of the plurality of remote monitoring units 4 and the type of error that the operator in charge of each of the plurality of remote monitoring units 4 cannot handle. The correspondence availability information (correspondence relationship in which the most recently transmitted one of the handling availability information and the handling non-handling information for each type of error received is associated with the remote monitoring unit 4) is created, and the created "handling availability information ” is stored in the storage unit 31 .

When an error occurs in the work line (error information is transmitted from one of the plurality of component mounting apparatuses 2A), the selection unit 32 of the server 3 selects One remote monitor 4 is selected. In this case, first, based on the presence status information stored in the storage unit 31, when an error occurs in the work line 2 (error information is transmitted from the component mounting apparatus 2A in which the error has occurred), the operator specifies the remote monitoring unit 4 whose seat presence status is set to the away state (that is, the operator is away from his post). Further, the selection unit 32 identifies the remote monitoring unit 4 for which the operator cannot handle the type of error that has occurred, based on the availability information stored in the storage unit 31 .

That is, in this embodiment, when an error occurs in the work line 2, the selection unit 32 of the server 3 specifies the remote monitoring unit 4 for which the operator has set the presence status to the absent state at that time. At the same time, the operator identifies the remote monitoring unit 4 for which the operator cannot handle the type of error.

As described above, the selection unit 32 of the server 3 identifies the remote monitoring unit 4 for which the operator has set the presence status to the away state, and also specifies the type of error that has occurred for the remote monitoring unit 4 for which the operator cannot handle. Once the monitoring units 4 are identified, one remote monitoring unit is selected from among the remote monitoring units 4 other than the identified remote monitoring units 4 as a target for sending error information about the error that has occurred. Here, when the selection unit 32 selects one remote monitoring unit 4 from the "remaining remote monitoring units", for example, the operator is free when the error information is sent ( The operator selects the remote monitoring unit 4 which is in charge of the remote monitoring unit 4 in which the operator has not performed the error resolving operation and whose time has elapsed the longest since the operator last performed the error resolving operation.

When the selection unit 32 selects one remote monitoring unit 4 as described above, the transfer unit 33 of the server 3 transfers the error information to the selected remote monitoring unit 4 . Therefore, since the error information is surely sent to the remote monitoring unit 4 where the operator is at his/her post, it is possible that the error occurred because the operator was away from his/her post. It is possible to prevent a situation in which time passes unnecessarily without being processed. In addition, since the error information is sent to the remote monitoring unit 4 in charge of the operator who does not consider the type of error that has occurred to be unsupportable, it is possible to prevent the situation in which the processing of the error takes too much time.

Next, the flow of control performed by the control section (mounting device control section 18) of the component mounting apparatus 2A constituting the work line 2, the control section (remote monitoring control section 41) of the server 3 and the remote monitoring section 4 will be described. 7 is a flow chart showing the flow of processing performed by the mounting device control unit 18, FIG. 8 is a flow chart showing the flow of processing performed by the server 3, and FIG. 9 is a flow chart showing the flow of processing performed by the remote monitoring control unit 41.

In FIG. 7, the mounting apparatus control section 18 of the component mounting apparatus 2A checks whether an error has occurred in the component mounting apparatus 2A to which it belongs at regular time intervals (several seconds) (step ST1). When it is detected that the error has occurred, the location where the error occurred (error occurrence location) is specified (step ST2). Then, all or part of the component mounting work is interrupted and the error elimination mode is entered (step ST3).

After entering the error resolution mode, the mounting apparatus control unit 18 moves the board camera 16 above the error occurrence location, causes the board camera 16 to image the error occurrence location, and acquires the image data as error information ( step ST4). Then, the acquired error information is transmitted to the server 3 (step ST5).

In FIG. 8, the server 3 checks whether error information has been sent from the work line 2 (from one of the plurality of component mounting apparatuses 2A) at regular time intervals (several seconds) (step ST11). When it is detected that information has been sent, the component mounting apparatus 2A that has sent the error information is specified. At the same time, the type of the transmitted error is grasped (step ST12).

When the server 3 identifies the component mounting apparatus 2A that has transmitted the error information and grasps the type of the transmitted error, the server 3 receives the presence status information transmitted from the remote monitoring unit 4 and stored in the storage unit 31. , the operator identifies the remote monitoring section 4 that is away from his/her post (that is, is away from the remote monitoring section 4 in charge) (step ST13). Also, after (or before) this specification, based on the compatibility information that is similarly received from the remote monitoring unit 4 and stored in the storage unit 31, it is transmitted (to the component mounting apparatus 2A). The operator identifies the remote monitoring unit 4 for which the type of the error that occurred cannot be handled (step ST14).

In step ST13, the server 3 identifies the remote monitoring unit 4 for which the operator is away from his post, and in step ST14 identifies the remote monitoring unit 4 for which the operator has determined that the type of error sent from the component mounting apparatus 2A is unsupportable. , from among the remaining remote monitoring units 4 excluding these remote monitoring units 4, one remote monitoring unit 4 to be the transfer destination of the error information is selected (step ST15). When the server 3 selects one remote monitoring unit 4 to which the error information is to be transferred in step ST15, the server 3 transfers the error information to the selected one remote monitoring unit 4 (step ST16).

In FIG. 9, the remote monitoring control unit 41 checks whether or not error information has been transferred from the server 3 at regular time intervals (several seconds) (step ST21). is detected, the error information (image of the error occurrence location) transferred from the server 3 is displayed on the display device 42 as the error elimination operation screen 51 (step ST22). As a result, the operator, while viewing the error information (the image of the error occurrence location) displayed on the display device 42, performs an operation to eliminate the error that has occurred in the component mounting apparatus 2A. When the operator performs an operation to eliminate the error, the remote monitoring control unit 41 transmits the operation signal (elimination operation signal) to the server 3 (step ST23).

After transferring the error information to the remote monitoring unit 4 in step ST16, the server 3 checks whether or not the remote monitoring unit 4 to which the error information was transferred has sent a clearing operation signal (step ST17 in FIG. 8). ). Then, when it is detected that a clearing operation signal has been transmitted from the remote monitoring unit 4 to which the error information has been transferred, the clearing operation signal is relayed to the component mounting apparatus 2A (the component mounting apparatus 2A in which the error has occurred). (step ST18).

After transmitting the error information to the server 3 in step ST5, the component mounting apparatus 2A checks whether the server 3 has transmitted a clearing operation signal (step ST6 in FIG. 7). Then, when it is detected that the canceling operation signal has been transmitted from the server 3, the action according to the transmitted canceling operation signal is executed (step ST7). Then, when the error is resolved (step ST8), the error resolution mode is exited, the interrupted state of the component mounting work is canceled (step ST9), and the process returns to step ST1. If the error is not resolved in step ST8, some kind of notification operation is performed (step ST10), and a new treatment waiting state is entered.

As described above, in the remote operation system 1 according to the present embodiment, each of the plurality of remote monitoring units 4 is configured such that the operator of the remote monitoring unit 4 is present at or away from the remote monitoring unit 4 in charge of the operator. The presence status setting unit 53 (the presence button 61 and the absence button 62) for setting whether or not the seat is in the seat status as the presence status, and the operator in charge of the remote monitoring unit 4 correspond to each type of error. A support availability setting unit 54 (a support availability button 63 and a support failure button 64 for each type of error) for setting availability, information on the presence status set by the presence status setting unit 53, and the operator's availability setting unit 54 is provided with a transmission unit 41b for transmitting to the server 3 information on whether or not to handle each type of error set in . Then, when an error occurs in the work line 2, the server 3 identifies the remote monitoring unit 4 whose seat presence status is set to the away state by the operator at that time, and a selection unit 32 that identifies the remote monitoring units 4 for which the operator cannot handle the type of , and selects one remote monitoring unit 4 from the remaining remote monitoring units 4 excluding the identified remote monitoring units 4; A transfer unit 33 is provided for transferring error information to one remote monitoring unit 4 selected by the selection unit 32 .

In the remote operation system 1 according to the present embodiment, error information is not transferred to the remote monitoring unit 4 where the operator is away from his/her post (leaving his seat). Even if the remote monitoring unit 4) in charge is left, the error resolution work in the entire work line 2 does not stop. Further, in the remote operation system 1 according to the present embodiment, since error information is not transferred to the remote monitoring unit 4 in charge of the operator who is in charge of the type of error that has occurred, the skill of the error resolution processing depends on the operator's individual skill. Even if there is a difference, the error resolution processing in the entire work line 2 does not stagnate.

As described above, in the remote operation system 1 according to the present embodiment, error information is not transferred to the remote monitoring unit 4 in charge of the operator who is incapable of handling the type of error that has occurred. Even if there are individual differences between operators, the error elimination work in the entire work line 2 does not stagnate and the productivity of the work line 2 is not affected.

Although the embodiments of the present invention have been described so far, the present invention is not limited to those described above, and various modifications and the like are possible. For example, the format of the operator self-setting screen 52 shown in FIG. 6 is merely an example. good. Also, the presence status setting unit 53 only needs to allow the operator to set the presence status by himself/herself, and the response availability setting unit 54 allows the operator to set the availability of response for each type of error by the operator. However, it is not necessarily required to be displayed on the screen of the display device 42 . Moreover, in the above-described embodiment, the work line 2 is composed of a plurality of component mounting apparatuses 2A, but the work line may be composed of apparatuses other than the component mounting apparatuses 2A.
