To do.

As shown in FIG. 2, the storage unit 89 stores the device position information 89a, the production program 89b, the feeder possession information 89c, the work information 89d, and the monitoring area information 89e. The device position information 89a is information that can specify the position of each device (here, the mounting machine 20, the feeder storage 60, and the management device 80) that constitutes the mounting line 11. The device position information 89a is, for example, information in which the identification information of each device and the position information are associated with each other. The position information may be, for example, a number assigned from the upstream side to the downstream side in the X direction, or may be an X coordinate. In the present embodiment, one light emitting unit 40 is arranged in each device constituting the mounting line 11, and the management control unit 88 is the position of each of the plurality of light emitting units 40 based on the device position information 89a. (Here, the position in the X direction) can also be specified. That is, the device position information 89a also serves as information that can specify the positions of the plurality of light emitting units 40. The production program 89b is a program that defines which component is mounted on which board by which mounting machine 20, and how many boards are mounted in this way.

The feeder holding information 89c is information about the feeder 30 set in each of the supply area 20A, the robot transfer area 50A, and the storage area 60A. The feeder possession information 89c includes, for example, area identification information that identifies each of the areas, a slot number that indicates the position of the feeder 30 in the area, and feeder information (ID information, a stored part type, and a component type) of the feeder 30. Information associated with information such as the number of parts). Based on this feeder possession information 89c, the management control unit 88 determines what kind of feeder 30 is installed in which position (slot) in each area, and which slot in each area is empty (state in which the feeder 30 is not installed). It is possible to specify whether or not it is. The feeder holding information 89c is updated to the latest state according to the attachment / detachment of the feeder 30 in each area. For example, when the feeder 30 is mounted on either the connector 24 or the connector 64, the mounted control unit (mounting control unit 28 or management control unit 88) acquires feeder information from the feeder 30 and manages control. Section 88 updates the feeder holding information 89c regarding the supply area 20A and the storage area 60A. Further, since the management control unit 88 knows the area where the mobile robot 50 next carries in / out and the feeder 30, the feeder possession information 89c regarding the robot transfer area 50A is updated based on the information. For example, the management control unit 88 is said to be housed in the mobile robot 50 when the feeder 30 is detached from either the connector 24 or the connector 64 and the feeder 30 is the target to be carried out by the mobile robot 50. The feeder holding information 89c regarding the robot transfer area 50A is updated. The mobile robot 50 has a connector similar to the connector 24, and the management control unit 88 may update the feeder possession information 89c by inputting information regarding attachment / detachment of the feeder 30 and feeder information from the mobile robot 50. The information on the number of parts in the feeder information may be information that can identify whether the number of parts in the feeder 30 is "Full" (unused) or "Empty" (already used in the mounting machine 20). However, it may be a value representing the remaining number of parts. In the latter case, the management control unit 88 acquires the remaining number of parts of each feeder 30 from the mounting control unit 28 at predetermined intervals, and updates the feeder possession information 89c.

The work information 89d is information related to the work performed by the mobile robot 50, such as which of the mounting machine 20 and the feeder storage 60 the mobile robot 50 moves to and in what order the feeder 30 is carried in and out. FIG. 3 is an explanatory diagram showing an example of work information 89d stored in the storage unit 89. As shown in FIG. 3, the work information 89d includes the work order in which the work is performed, the position information (referred to as the target position information) of the work target device to perform the work, the work content information, the scheduled work time, and the work is completed. It is associated with the completion information indicating whether or not it has been done. The target position information may be, for example, the same information as the position information of the device included in the device position information 89a. In the present embodiment, in the target position information of FIG. 3, "00" represents the position of the feeder storage 60, and "01" to "05" are the positions from the left among the plurality of mounting machines 20. Represents. The target position information is the identification information of the device, and the target position information and the position information of the work target device may be associated with each other via the device position information 89a. The work content information includes, for example, a work type indicating whether to supply (carry in) or collect (carry out) the feeder 30, and information on the slot number of the work target. The work target slot number is the slot number of the robot transfer area 50A of the mobile robot 50 and the slot number of the supply area 20A or the storage area 60A of the work target device. When the work type is "supply", the feeder 30 at the slot number position of the mobile robot 50 is supplied to the slot number position of the work target device. When the work type is "collection", the feeder 30 at the slot number position of the work target device is collected at the slot number position of the mobile robot 50. In the present embodiment, one "work" corresponding to one work sequence includes the movement of the mobile robot 50 and the supply or collection of the feeder 30 by the mobile robot 50. For example, the work corresponding to the work order "004" includes moving to the third mounting machine 20 (target position information "03") from the left, that is, transporting the feeder 30, and supplying the feeder 30 to the mounting machine 20. Includes. However, if the work target device does not change from the immediately preceding work (for example, the work in the work order "002" and "003"), the mobile robot 50 may not move as a result. The scheduled work time is the time when the work specified in the corresponding work content information should be completed. This scheduled work time is set, for example, by a production program so that the feeder 30 containing the necessary parts is supplied from the mobile robot 50 to each mounting machine 20 before the mounting line 11 is stopped due to a shortage of parts of the feeder 30. It is determined in advance by the operator based on 89b and the like. The plurality of operations included in the work information 89d are basically executed according to the work order. Therefore, the scheduled work time corresponding to a certain work order is set as a time so that any work corresponding to the subsequent work order can be completed without stopping the mounting line 11. In other words, regardless of whether or not the work corresponding to a certain work sequence is the supply of the feeder 30 to the mounting machine 20, if the work is not completed by the scheduled work time, then one of the mounting machines is used. The feeder 30 is not supplied to the 20 in time, and the mounting line 11 is stopped. In the present embodiment, the scheduled work time is a time based on the operation start time of the mounting line 11, that is, an elapsed time from the operation start time. In FIG. 3, “completion” indicates that the corresponding work has been completed, and “−” indicates that the corresponding work has not been completed. When the supply of the feeder 30 to the mounting machine 20 is delayed due to, for example, the operation of the mobile robot 50 being stopped, the management control unit 88 has a mounting line 11 due to a shortage of parts based on the production program 89b and the feeder possession information 89c. The work information 89d may be changed so as to shorten the stop time of the work information 89d as much as possible.

The monitoring area information 89e is information that can identify the monitoring area S of the surrounding monitoring sensor 55 of the mobile robot 50. The feeder possession information 89c includes, for example, information representing the relative position of the surrounding monitoring sensor 55 with respect to the position of the mobile robot 50. In the present embodiment, the monitoring area information 89e includes information that one left and right device is included in the monitoring area S with reference to the position of the mobile robot 50. The monitoring area information 89e may include information representing the monitoring area S in XY coordinates relative to the mobile robot 50 as the origin.

Next, the operation of the mounting system 10 configured in this way, particularly the control of the mobile robot 50 performed by the management control unit 88, and the notification of a warning to the operator when the feeder 30 is not supplied to the mounting machine 20 by the mobile robot 50. And will be explained. FIG. 4 is a flowchart showing an example of work control processing. For example, when the management control unit 88 inputs an operation start instruction of the mounting line 11 from the operator via the input device 84, the management control unit 88 causes a plurality of mounting machines 20 of the mounting line 11 to start mounting the components on the board, and the operation start instruction is started. Start work control processing. When the work control process is started, the management control unit 88 first determines the next work to be performed by the mobile robot 50 based on the work information 89d (step S100). The management control unit 88 identifies, for example, the work having the earliest work order among the unfinished works stored in the work information 89d, and determines the work to be performed next by the mobile robot 50.

Subsequently, the management control unit 88 derives the estimated work time of the determined work (step S110). The estimated work time is derived based on, for example, the movement time of the mobile robot 50 and the loading / unloading time of the feeder 30 required from the present time to the completion of the work. The management control unit 88 derives the movement time of the mobile robot 50 based on, for example, the current position of the mobile robot 50 and the target position information of the work determined in step S100. The current position of the mobile robot 50 is derived, for example, based on the detection signals of the robot detection sensors 25 and 65 input by the management control unit 88 from the mounting control unit 28 and the robot detection sensor 65. The management control unit 88 may acquire the current position of the mobile robot 50 based on the encoder 53 from the robot control unit 58. Regarding the loading / unloading time of the feeder 30, in the present embodiment, the time required for each work type, such as the time required for supplying one feeder 30 and the time required for collecting one feeder 30, is stored in advance in the storage unit 89. .. Then, the management control unit 88 acquires the loading / unloading time of the feeder 30 based on the work type of the work determined in step S100 and the time for each work type stored in the storage unit 89. The management control unit 88 may derive the loading / unloading time of the feeder 30 in consideration of, for example, the slot number included in the work content information.

When the estimated work time is derived, the management control unit 88 acquires the scheduled work time of the work determined in step S100 from the storage unit 89, and derives the difference between the scheduled work time and the estimated work time as a margin time (step). S120). Then, the management control unit 88 transmits a work command to the mobile robot 50 to start the work determined in step S100 (step S130). The work command includes, for example, target position information and work content information of the work determined in step S100.

The robot control unit 58 of the mobile robot 50 that has received the work command executes the work based on the received work command. At this time, when an obstacle is detected in the monitoring area S based on the detection signal from the surrounding monitoring sensor 55, the robot control unit 58 stops the operation of the mobile robot 50 (here, the movement and the loading / unloading of the feeder 30). Then, the operation stop signal is transmitted to the management control unit 88. After that, when no obstacle is detected in the monitoring area S, the robot control unit 58 releases the operation stop and continues the work, and transmits an operation stop release signal to the management control unit 88. Further, when the work is completed, the robot control unit 58 transmits a work completion signal to the management control unit 88.

When the work command is transmitted in step S130, the management control unit 88 determines whether or not the mobile robot 50 has stopped operating based on whether or not the above-mentioned operation stop signal has been received (step S140). If the mobile robot 50 has not stopped its operation, the management control unit 88 determines whether or not the mobile robot 50 has completed the work based on whether or not the above-mentioned work completion signal has been received (step S150). If the work is not completed, the management control unit 88 executes the processes after step S140. That is, the management control unit 88 waits for either the operation of the mobile robot 50 to stop or the work to be completed. When it is determined in step S150 that the work is completed, the management control unit 88 updates the work completion information determined in step S100 in the work information 89d from the information indicating incompleteness to the information indicating completion (step S160). .. Subsequently, the management control unit 88 determines whether or not all the work included in the work information 89d has been completed (step S170), and if there is any work that has not been completed, executes the processes after step S100. .. On the other hand, when all the work is completed, the management control unit 88 ends this routine.

In this way, when the operation of the mobile robot 50 does not stop, the management control unit 88 repeats steps S100 to S170 to cause the mobile robot 50 to sequentially execute the work included in the work information 89d. As a result, the mobile robot 50 collects the unused feeder 30 stored in the feeder storage 60, transports the unused feeder 30 to the mounting machine 20, and supplies the unused feeder 30 to the mounting machine 20. The work of collecting the feeder 30 from the mounting machine 20 and the work of transporting the used feeder 30 to the feeder storage 60 and supplying it to the feeder storage 60 are performed according to the work order of the work information 89d. .. When the management control unit 88 acquires the information of the feeder 30 newly supplied or collected via the connector 24 or the connector 64, for example, the feeder holding information 89c is updated based on the acquired information.

On the other hand, if it is determined in step S140 that the mobile robot 50 has stopped operating, the management control unit 88 starts timing the stop time of the mobile robot 50 (step S180), and the margin time derived in step S120 and the timed stop time. The difference from the above is derived as the remaining margin time Tr (step S190). The remaining margin time Tr is the remaining time for the work determined in step S100 to be performed at the scheduled work time. For example, when the derived remaining margin time is 15 minutes, if the operation stop of the mobile robot 50 is released within 15 minutes from now, the work determined in step S100 is before the scheduled work time or the work stop time. It can be completed, that is, it will be in time for the scheduled work time. Further, the remaining margin time Tr becomes shorter as the timed stop time of the mobile robot 50 is longer, that is, as the duration of the stop of the mobile robot 50 is longer.

Subsequently, the management control unit 88 performs a determination process for determining the magnitude relationship between the derived remaining margin time Tr and the predetermined first to third threshold values T1 to T3 (step S200). The first threshold value Tr is the minimum value of a value at which the remaining margin time Tr can be regarded as sufficiently long so that it is not necessary to notify the operator of the warning, and is set to 10 minutes in the present embodiment. The second threshold value T2 is the minimum value of a value that can be regarded as having a certain amount of remaining margin time Tr, although it is necessary to notify the operator of the warning, and is set to 5 minutes in the present embodiment. The third threshold value T3 is the minimum value of the remaining margin time Tr for the work determined in step S100 to be in time for the scheduled work time, and is set to a value of 0 in the present embodiment. When the management control unit 88 determines in step S200 that the remaining margin time Tr is equal to or greater than the first threshold value T1, the management control unit 88 does not notify the operator of the warning and directly performs the process of step S240 described later. When the management control unit 88 determines in step S200 that the remaining margin time Tr is less than the first threshold value T1 and greater than or equal to the second threshold value T2, the management control unit 88 notifies the operator of a warning in the first aspect (step S210), and the remaining time is remaining. When it is determined that the margin time Tr is less than the second threshold value T2 and equal to or more than the third threshold value T3, a warning to the operator is notified in the second mode (step S220), and the remaining margin time Tr is less than the third threshold value T3. If it is determined that this is the case, a warning to the operator is notified in the third aspect (step S230). Details will be described later, but in the first to third aspects, the warning modes are set so that the warning to the operator tends to be stronger in this order. Whether or not the management control unit 88 has received the above-mentioned operation stop release signal after determining in step S200 that the remaining margin time Tr is equal to or greater than the first threshold value T1 or after performing any of steps S210 to S230. Based on the above, it is determined whether or not the operation stop of the mobile robot 50 has been released (step S240). Then, when it is determined in step S240 that the operation stop of the mobile robot 50 has not been released, the management control unit 88 performs the processes after step S190. On the other hand, when the operation stop of the mobile robot 50 is released in step S240, the management control unit 88 performs the processes after step S150.

As described above, when the operation stop of the mobile robot 50 occurs, the management control unit 88 repeats steps S190 to S240 until it is determined in step S240 that the operation stop of the mobile robot 50 has been released. That is, the management control unit 88 does not notify the warning according to the process of deriving the remaining margin time Tr based on the timed stop time and the length of the remaining margin time Tr, or the warning in the first to third aspects. And the process of performing the above are repeated alternately. Here, when the remaining margin time Tr is equal to or greater than the first threshold value T1 in step S200, the management control unit 88 does not notify the warning even if the mobile robot 50 is stopped. That is, when the remaining margin time Tr is equal to or greater than the first threshold value T1, the management control unit 88 does not have a state in which the feeder 30 is not supplied to the mounting machine 20 because the remaining margin time Tr is sufficiently long (that is, the mounting line 11 It is determined that no stop occurs), and it is determined that the warning is unnecessary. On the other hand, when the remaining margin time Tr becomes less than the first threshold value T1 in step S200, the management control unit 88 determines that the feeder 30 is not supplied to the mounting machine 20 due to the operation stop of the mobile robot 50. , A warning is given in any of the first to third aspects. Specifically, the management control unit 88 first notifies the warning in the first aspect when the remaining margin time Tr becomes less than the first threshold value T1. Then, as the duration of the operation stop of the mobile robot 50 becomes longer and the remaining margin time Tr becomes shorter, the warning is notified in the second aspect, which is a stronger warning than the first aspect, and the third aspect, which is a stronger warning. Notify a warning in a mode.

In the first embodiment, in the first aspect, the light emitting unit 40 of the device corresponding to the current position of the mobile robot 50 and the monitoring area S emits yellow light, and further, the device corresponding to the current position of the mobile robot 50 and the monitoring area S. The display operation unit 26 displays a warning screen including the remaining margin time Tr. In step S210, the management control unit 88 derives the current position of the mobile robot 50 in the same manner as in the case of executing step S110, and based on the derived current position and the device position information 89a, the management control unit 88 of each device of the mounting line 11 Among them, a device facing the mobile robot 50, that is, located behind the mobile robot 50 is specified. Further, the management control unit 88 faces the monitoring area S of the mobile robot 50 in each device of the mounting line 11 based on the derived current position, the monitoring area information 89e, and the device position information 89a, that is, the monitoring area. Identify the device located behind S. Then, the management control unit 88 controls the light emitting unit 40 and the display operation unit 26 of the specified device to notify the warning in the first aspect. For example, when the mobile robot 50 is stopped in the state of FIG. 1, the management control unit 88 specifies the mounting machine 20 second from the left as a device corresponding to the current position of the mobile robot 50. Further, the management control unit 88 identifies the second mounting machine 20 from the left and the devices for one left and right of the mounting machine 20 as devices corresponding to the monitoring area S. When the specified device is the feeder storage 60 or the management device 80, the management control unit 88 does not have a display unit such as the display operation unit 26, so that the management control unit 88 emits light (light emission). Only the unit 46 or the light emitting unit 48) is controlled. The remaining margin time Tr displayed by the management control unit 88 on the display operation unit 26 is, for example, a value derived in the immediately preceding step S190. On the warning screen displayed by the management control unit 88 on the display operation unit 26, not only the remaining margin time Tr but also the mounting line 11 is displayed unless the obstacle is removed before the displayed remaining margin time Tr reaches the value 0. A sentence to the effect that it will be stopped may also be included.

In the present embodiment, the second aspect is the same as the first aspect except that the light emitting unit 40 emits light in red. Therefore, in step S220, the management control unit 88 controls the light emitting unit 40 and the display operation unit 26 in the same manner as in step S210 except for controlling the emission color of the light emitting unit 40.

In the third embodiment, in the third aspect, the display operation unit 26 displays a warning screen including the delay time from the scheduled work time instead of the remaining margin time Tr, and the display operation unit 76 of the mobile terminal 70 also displays the display operation. It is the same as the second aspect except that the warning screen similar to that of the part 26 is displayed. In step S230, the management control unit 88 controls the light emitting unit 40 in the same manner as in step S210, and controls the display operation unit 26 in the same manner as in step S210 except that the delay time is displayed. Further, the management control unit 88 transmits a control signal to the mobile terminal 70 so as to display a warning screen similar to that of the display operation unit 26. The terminal control unit 78 of the mobile terminal 70 displays a warning screen including a delay time on the display operation unit 76 based on the received control signal. The delay time is another name for the remaining margin time Tr when the value is negative (when the stop time is longer than the margin time). Further, although the delay time displayed on the display operation unit 26 and the display operation unit 76 is an absolute value in the present embodiment, it may remain a negative value. For example, in the state where the absolute value of the delay time is 30 seconds, even if the operation stop of the mobile robot 50 is released now, the work determined in step S100 is completed 30 seconds after the scheduled work time. It is in the state. The absolute value of the delay time becomes longer as the duration of the stop of the mobile robot 50 becomes longer. The management control unit 88 may time the elapsed time from the time when the remaining margin time Tr becomes 0, and use the timed value as the delay time.

The operator who has confirmed the warning of any of the first to third aspects confirms whether or not he / she or another object is an obstacle that hinders the operation of the mobile robot 50, and confirms his / her own movement or other. Take measures to remove obstacles such as removing objects in. Further, in the present embodiment, of the light emitting unit 40 and the display operation unit 26, only the one at the current position of the mobile robot 50 and the position corresponding to the monitoring area S notifies the warning. Therefore, the operator can grasp the area where the presence or absence of an obstacle should be confirmed depending on which of the light emitting unit 40 and the display operation unit 26 notifies the warning. Further, in the present embodiment, in the third aspect, the display operation unit 76 of the mobile terminal 70 also notifies the warning. Therefore, the operator who possesses the mobile terminal 70 is more likely to notice the warning than when the warning is notified only from the light emitting unit 40 and the display operation unit 26.

Here, the correspondence between the components of the present embodiment and the components of the present disclosure will be clarified. The mounting machine 20 of the present embodiment corresponds to the mounting machine of the present disclosure, the mounting line 11 corresponds to the mounting line, the mobile robot 50 corresponds to the supply device, and the light emitting unit 40, the display operation unit 26, and the display operation unit 76. Corresponds to the notification unit. Further, the management control unit 88 that executes steps S110, 120, S180 to S240 of the work control process of FIG. 4 corresponds to the notification control unit, the surrounding monitoring sensor 55 corresponds to the monitoring sensor, and the storage unit 89 serves as the storage unit. Equivalent to.

In the mounting system 10 described in detail above, when the feeder 30 is not supplied to the mounting machine 20 by the mobile robot 50, at least the light emitting unit 40 and the display operation unit 26 notify the warning. As a result, the mounting system 10 can urge the operator to take appropriate measures such as removing the cause of the feeder 30 not being supplied (for example, an obstacle that hinders the operation of the mobile robot 50). Therefore, in this mounting system 10, the state in which the feeder 30 is not supplied to the mounting machine 20 can be easily resolved at an early stage, and a decrease in the operating rate of the mounting line 11 can be suppressed. Further, in the mounting system 10, when the management control unit 88 performs the determination process of step S200 and determines that the feeder 30 is not supplied to the mounting machine 20 by this determination process (here, the remaining margin time Tr is set in step S200). When it is less than the first threshold value T1), the management control unit 88 controls at least the light emitting unit 40 and the display operation unit 26 to notify the warning.

Further, the management control unit 88 acquires the scheduled work time in step 120, and in step S200, the remaining margin time Tr derived based on the scheduled work time is up to the scheduled work time depending on whether or not the value is less than 0. It is determined whether or not the work is performed, and whether or not the feeder 30 is supplied to the mounting machine 20 is determined by this determination. Then, when it is determined in this determination that the feeder 30 is not supplied to the mounting machine 20 (here, when the remaining margin time Tr is less than the third threshold value T3, that is, the value is less than 0), the management control unit 88 is the light emitting unit. 40. The display operation unit 26 and the display operation unit 76 are controlled to notify the warning in the third aspect. Therefore, the management control unit 88 can appropriately determine whether or not the feeder 30 is supplied to the mounting machine 20 based on the scheduled work time.

Further, when the management control unit 88 determines that the work is not performed by the scheduled work time (here, when the remaining margin time Tr is less than 0), the management control unit 88 controls the display operation unit 26 to control the scheduled work time. Notify the delay time from. Therefore, since the mounting system 10 can notify the magnitude of the decrease in the operating rate of the mounting line 11 depending on the length of the delay time, the operator can grasp the state of the mounting line 11 in more detail.

Furthermore, the management control unit 88 acquires the scheduled work time in step 120, and in step S200, the scheduled work time is set based on the remaining margin time Tr derived based on the scheduled work time and the second threshold value T2. It is determined whether or not the work is performed by a predetermined time before (here, 5 minutes before), and whether or not the feeder 30 is supplied to the mounting machine 20 is determined by this determination. Then, when it is determined in this determination that the feeder 30 is not supplied to the mounting machine 20, the management control unit 88 controls the light emitting unit 40 and the display operation unit 26 to notify the warning in the first aspect. Therefore, the mounting system 10 notifies the warning at least by a predetermined time earlier than the timing when the work is not performed by the scheduled work time (the timing when the remaining margin time Tr becomes less than 0). As a result, it is possible to avoid the stoppage of the mounting line 11 if the operator responds within the predetermined time. Therefore, in this mounting system 10, it is possible to further reduce the decrease in the operating rate of the mounting line 11.

Then, when the management control unit 88 determines that the work is not performed before the predetermined time of the scheduled work time, the management control unit 88 displays the remaining margin time Tr which is the remaining time for the work to be performed at the scheduled work time. Notify from 26 (steps S210 and S220). Therefore, the worker can judge the urgency of the response based on the length of the remaining margin time Tr. For example, in a situation where the worker does not stop the mounting line 11 even if the cause of the operation stop of the mobile robot 50 is removed after the completion of his / her current work based on the length of the notified remaining margin time Tr. It can be determined whether there is a situation in which the mounting line 11 is stopped unless the cause of the operation stop of the mobile robot 50 is removed by interrupting the current work of the mobile robot 50. Therefore, the mounting system 10 can urge the operator to take a more appropriate response.

Further, the management control unit 88 continues when the state in which the feeder 30 is determined not to be supplied to the mounting machine 20 (here, the state in which the remaining margin time Tr is less than the first threshold value T1 in step S200) continues. At least one of the light emitting unit 40, the display operation unit 26, and the display operation unit 76 is set so that the longer the duration of the state (here, the shorter the remaining margin time Tr) is, the stronger the warning is given. Control. More specifically, the management control unit 88 sets the emission color of the light emitting unit 40 to yellow before the remaining margin time Tr becomes less than the second threshold value T2, and the remaining margin time Tr is less than the second threshold value T2 and the third threshold value. After T3 or higher, the emission color of the light emitting unit 40 is changed to red, which indicates a stronger warning. Further, after the remaining margin time Tr becomes less than the third threshold value T3, the management control unit 88 causes the display operation unit 76 to notify the warning in addition to the light emitting unit 40 and the display operation unit 26. Therefore, the mounting system 10 can urge the operator to respond faster as the duration of the state in which the feeder 30 is not supplied is longer, so that it is possible to suppress the suspension of the mounting line 11 for a longer period of time. In addition, the operator can determine the degree of urgency of the response depending on which of the first to third aspects of the warning is given.

It goes without saying that the present invention is not limited to the above-described embodiment, and can be implemented in various aspects as long as it belongs to the technical scope of the present invention.

For example, in the above-described embodiment, when an obstacle is detected in the monitoring area S, the mobile robot 50 is stopped until the obstacle is removed, but even if the obstacle is detected, the mobile robot 50 is stopped. Work may be performed. FIG. 5 is a flowchart showing an example of the work control process of the modified example in this case. Of the work control processes of FIG. 5, the same processes as those of the work control process of FIG. 4 are given the same step numbers, and detailed description thereof will be omitted. In this modification, if the mobile robot 50 is loading and unloading the feeder 30, the robot control unit 58 continues loading and unloading as it is even if an obstacle is detected in the monitoring area S, and does not transmit an operation stop signal. That is, the robot control unit 58 only stops moving when an obstacle is detected in the monitoring area S. In the work control process of the modified example of FIG. 5, when the management control unit 88 receives the operation stop signal from the robot control unit 58 in step S140 and determines that the mobile robot 50 has stopped the operation (here, the movement is stopped). Notifies a warning (step S300). The warning may be, for example, any aspect of steps S210 to S230 of FIG. The management control unit 88 may continuously notify the warning until it is determined that the obstacle has been removed in step S360 described later. Further, as in the above-described embodiment, the warning mode may be different depending on the stop time. Subsequently, the management control unit 88 determines whether or not the obstacle detected by the surrounding monitoring sensor 55 is only one of the left side and right side monitoring areas Sa and Sb (step S310). For example, the management control unit 88 acquires the detection states of the left and right monitoring sensors 55a and 55b from the robot control unit 58 and makes this determination. When the obstacle is only one of the left side and right side monitoring areas Sa and Sb, the management control unit 88 executes in the area in the direction without obstacles with reference to the position of the mobile robot 50 in the arrangement direction of the mounting line 11. It is determined whether or not there is another work possible (step S320). In step S320, the management control unit 88 first acquires the current position of the mobile robot 50, and which of the acquired current position and the left and right monitoring sensors 55a and 55b does not detect an obstacle. Based on the information and the device position information 89a, the device in the mounting line 11 in which the mobile robot 50 can move without being obstructed by obstacles is specified. Then, the management control unit 88 includes whether or not the work information 89d includes the unfinished work in which the specified device is designated as the work target device, and the mobile robot 50 is ready to execute the work. The determination in step S320 is performed accordingly. Whether or not the work is ready to be executed is, for example, whether or not the feeder 30 to be supplied is already accommodated in the robot transfer area 50A if the work type of the work is "supply". Further, if the work type of the work is "collection", it is whether or not there is a space for accommodating the feeder 30 in the robot transfer area 50A. The management control unit 88 determines whether or not the mobile robot 50 is ready to perform the work, for example, based on the feeder possession information 89c. The management control unit 88 may change the slot number of the mobile robot 50 included in the work content information of the work information 89d, if necessary. For example, the work from the work order "001" to "004" in FIG. 3 is completed, and the mobile robot 50 moves from the state shown in FIG. 1 to the left side of the mounting machine 20 as the work in the next work order "005". It is assumed that only the left side monitoring sensor 55a detects an obstacle while moving in the direction, and the mobile robot 50 stops moving. In this case, the management control unit 88 is in an area where the mobile robot 50 can move the four mounting machines 20 from the right, which are devices on the right side of the current position of the mobile robot 50 in the mounting line 11. To identify. Then, the management control unit 88 examines the work information 89d and sets any one of the specified devices (here, the mounting machine 20 whose target position information is “02” to “05”) as the work target device, which is incomplete. As the work, the work of the work order "006" and "007" is specified. Then, if the mobile robot 50 is ready to perform at least one of these tasks, the management control unit 88 makes an affirmative determination in step S320. When it is determined that there is another work that can be executed in step S320, the management control unit 88 determines that the other work is to be performed next (step S330), and transmits a work command for that work to the mobile robot 50. (Step S340). When there are a plurality of other operations that can be executed, the management control unit 88 may determine the operation having the earliest operation order among them as the "next operation" in step S330. Then, the management control unit 88 waits until the mobile robot 50 completes the work (step S350). The management control unit 88 determines in step S310 that obstacles exist in both the left and right monitoring areas Sa and Sb, determines that there is no other work that can be performed in step S320, or works in step S350. If it is determined that the process is completed, it is determined whether or not the obstacle has been removed (step S360). For example, when the operator confirms the warning in step S300 and removes the obstacle, he / she inputs that he / she has removed the obstacle by operating at least one of the display operation units 26, 56, 76, or the display 86. The management control unit 88 acquires an obstacle removal signal indicating that fact. In step S360, the management control unit 88 determines in step S360 based on whether or not the obstacle removal signal has been acquired. Then, if it is determined in step S360 that the obstacle has not been removed, the management control unit 88 executes the processes after step S310. That is, until the obstacle is removed, the management control unit 88 causes the mobile robot 50 to execute another work that can be executed without being hindered by the obstacle. In addition, if there is no other work that can be performed without being hindered by the obstacle, or if the obstacle exists in both the left and right monitoring areas Sa and Sb and the mobile robot 50 cannot move, the management control is performed. Part 88 waits for the obstacle to be removed. On the other hand, if it is determined in step S360 that the obstacle has been removed, the management control unit 88 executes the processes after step S100. That is, the management control unit 88 determines the work having the earliest work order among the unfinished works stored in the work information 89d as the work to be performed next, and executes the unfinished work to the mobile robot 50 according to the work order. Let me do it. As described above, in the work control process of the modified example, the management control unit 88 causes the mobile robot 50 to perform the work in the work order of the work information 89d when the operation of the mobile robot 50 is not stopped due to an obstacle. .. On the other hand, when the mobile robot 50 stops operating due to an obstacle, the management control unit 88 does not have to follow the work order if there is another work that can be performed before the operator removes the obstacle. The mobile robot 50 is made to execute the work first. Therefore, in the mounting system 10 of this modified example, it is possible to further suppress a decrease in the operating rate of the mounting line 11 even if the obstacle is not immediately removed. If the mobile robot 50 stops operating due to an obstacle while waiting for the work to be completed in step S350, the management control unit 88 may wait for the obstacle to be removed in step S360.

In the above-described embodiment, when the management control unit 88 inputs a warning stop operation from the operator via the display operation unit 26, the mobile robot 50 does not issue any warnings in steps S210 to S230 thereafter, and the mobile robot 50 is in step S240. You may wait until it is determined that the suspension of operation of is released. In this way, the worker who confirms the warning can arbitrarily stop the warning.

In the above-described embodiment, one work corresponding to one work sequence includes, but is not limited to, the movement of the mobile robot 50 and the supply or collection of the feeder 30 by the mobile robot 50. For example, the transfer of the feeder 30 performed by the mobile robot 50 and the supply of the feeder 30 may be included in the work information 89d as separate operations. In this case, the scheduled work time may be set for each of the operations of the transfer of the feeder 30 and the supply of the feeder 30.

In the above-described embodiment, the scheduled work time is set for all the work included in the work information 89d, but is not limited to this. For example, the scheduled work time may be set for the work including at least one of the transfer of the feeder 30 performed by the mobile robot 50 and the supply of the feeder 30 to the mounting machine 20. At this time, for example, when the scheduled work time is not associated with the work determined in step S100, the management control unit 88 manages the work determined in step S100 among the operations to which the scheduled work time is associated. Steps S110, S120, and S190 may be performed for the specified work by identifying the unfinished work having the closest work order to the above.

In the above-described embodiment, the scheduled work time is set to the time when the work specified by the corresponding work content information should be completed, but the time is not limited to this, and may be, for example, the time when the work should be started, or the position of the work target device. It may be the time when the mobile robot 50 should arrive at. For example, as in the modified example described with reference to FIG. 5, when an obstacle is detected in the monitoring area S, the mobile robot 50 does not stop the loading / unloading of the feeder 30 but only the movement. When the robot 50 arrives at the position of the work target device, the supply or recovery of the feeder 30 is performed without stopping. In such a case, the scheduled work time is set as the time when the mobile robot 50 should arrive at the position of the work target device, and if the mobile robot 50 arrives at the position of the work target device by the scheduled work time, the feeder 30 is supplied or It may be considered that the collection is in time.

In the above-described embodiment, the management control unit 88 uses at least one of the light emitting unit 40, the display operation unit 26, or the display operation unit 76 to notify the warning, but in addition to or instead of this, the display operation unit 56 or The display 86 may be used to notify the warning. Further, the notification unit for notifying the warning is not limited to a device for visually notifying the warning such as the light emitting unit 40 and the display operation unit 26, but may be a device such as a speaker for notifying the warning by sound.

In the above-described embodiment, the management control unit 88 compares the remaining margin time Tr with the first to third threshold values T1 to T3, and switches the first to third aspects stepwise, but is limited to this. Absent. The management control unit 88 notifies at least one of one or more notification units so that the shorter the remaining margin time Tr (the longer the duration of the state in which the feeder 30 is not supplied), the stronger the warning tends to be given. You just have to control it. For example, the management control unit 88 may continuously change the mode of warning according to the length of the remaining margin time Tr. For example, when the warning is notified by sound from the speaker, the management control unit 88 may continuously increase the volume of the warning as the remaining margin time Tr becomes shorter. Further, the management control unit 88 does not have to change the mode of the warning according to the remaining margin time Tr.

In the above-described embodiment, the management control unit 88 gives a stronger warning as the remaining margin time Tr becomes shorter, but the notification is not limited to this. For example, the management control unit 88 may give a notification with a tendency to give a stronger warning as the stop time for starting the time measurement in step S180 becomes longer. In this case, the management control unit 88 does not have to derive the margin time and the remaining margin time Tr, and the work information 89d may not include the information of the scheduled work time.

In the above-described embodiment, the management control unit 88 notifies the warning if the remaining margin time Tr is larger than the value 0 but less than the first threshold value T1, but the present invention is not limited to this, and the remaining margin time Tr is less than the value 0. The warning may be notified only after becoming. Alternatively, when it is determined in step S140 that the mobile robot 50 has stopped operating, the management control unit 88 may determine that the feeder 30 is not supplied by the mobile robot 50 and immediately notify the warning. In this case, the management control unit 88 does not have to derive the margin time and the remaining margin time Tr, and the work information 89d may not include the information of the scheduled work time.

In the above-described embodiment, the management control unit 88 notifies the light emitting unit 40 and the display operation unit 26 of the device corresponding to the current position of the mobile robot 50 and the monitoring area S among the light emitting unit 40 and the display operation unit 26.

A notification control unit for notifying the warning may be provided.

In the mounting system of the present disclosure, the notification control unit acquires the scheduled work time of the work including at least one of the transfer of the member performed by the supply device and the supply of the member to the mounting machine, and the determination process. Then, it may be determined whether or not the member is supplied depending on whether or not the work is performed by the scheduled work time. In this way, the notification control unit can appropriately determine whether or not the member is supplied based on the scheduled work time.

Here, "the work is performed by the scheduled work time" may mean that the work is started by the scheduled work time or that the work is completed by the scheduled work time. Good.

In the implementation system of the present disclosure, when it is determined that the work is not performed by the scheduled work time, the notification control unit controls the notification unit to notify the delay time from the scheduled work time. May be good. In this way, the mounting system can notify the magnitude of the decrease in the operating rate of the mounting line depending on the length of the delay time, so that the operator can grasp the state of the mounting line in more detail.

In the mounting system of the present disclosure, the notification control unit acquires the scheduled work time of the work including at least one of the transfer of the member performed by the supply device and the supply of the member to the mounting machine, and the determination process. Then, it may be determined whether or not the member is supplied depending on whether or not the work is performed by a predetermined time before the scheduled work time. In this way, this mounting system notifies the warning at least a predetermined time earlier than the timing when the work is not performed by the scheduled work time, so if the worker responds within the predetermined time, the mounting line is stopped. It can be avoided. Therefore, this mounting system can further reduce the decrease in the operating rate of the mounting line.

In this case, when the notification control unit determines that the work is not performed by the predetermined time before the scheduled work time, the notification control unit notifies the remaining time for the work to be performed at the scheduled work time. It may be notified from the unit. In this way, the worker can judge the urgency of the response based on the length of the remaining time. Therefore, this implementation system can encourage workers to take more appropriate action.

In the mounting system of the present disclosure, when one or more of the notification units exist and the state of determining that the member is not supplied by the determination process continues, the duration of the state is long. At least one of the notification units may be controlled so that the notification tends to give a moderately stronger warning. In this way, the mounting system can urge the operator to respond more quickly as the duration of the state in which the member is not supplied is longer, so that it is possible to suppress the prolonged stoppage of the mounting line. Here, "the tendency to give a stronger warning as the duration of the state is longer" means that the strength of the warning is continuously changed according to the length of the duration, or stepwise depending on the length of the duration. Including the case of changing the strength of the warning. Further, the notification control unit may have different warning intensities by different notification modes in the same notification unit, or may give different warnings by different notification units among a plurality of notification units. The strength may be different, or the strength of the warning may be different by making the number of the notification units for giving a warning different among the plurality of notification units.

In this case, the notification control unit may control at least one of the notification units so that the notification control unit notifies a stronger warning after the threshold value is exceeded than before the duration exceeds the threshold value. Good.
