[0008] [Summary of the embodiments of the present disclosure] (1) A component mounting system according to an embodiment is a component mounting line in which a plurality of devices for mounting components on a substrate are arranged along a transport path for the substrate, the devices having a communication unit, and at least one of the devices having an operation unit that receives a pre-preparation instruction for shutdown from an operator, and when the device having the operation unit receives the pre-preparation instruction at the operation unit, the device instructs at least one other device to perform pre-preparation for shutdown via the communication unit, and the device that received the pre-preparation instruction from the operator and at least one other device that has been instructed by the device to perform the pre-preparation each perform pre-preparation for shutdown.

[0009] The above "shutdown" refers to cutting off the power supply to the device. The above "instructing the execution of preparations for shutdown via the communication unit" includes cases where a device that has received a preparation instruction from an operator directly communicates with another device to instruct the execution of preparations, and cases where an instruction is given indirectly via a computer outside the component mounting line.

[0010] Conventionally, when multiple devices making up a component mounting line are made to perform shutdown preparations and then shut down, an operator would move to a device, instruct it to perform preparations, wait until preparations were completed, shut down that device, and then move on to the next device. Alternatively, after instructing it to perform preparations, the operator would move to the next device and instruct it to perform preparations, and after instructing all the devices to perform preparations, the operator would move back between the devices and shut down each device. For this reason, in the past, it was necessary to issue instructions to each machine individually to execute preparatory work, which took time. Furthermore, there was a loss of time due to waiting time for each machine (the time spent waiting until preparatory work was completed) and the time lost traveling back and forth between machines. This was one of the factors that reduced the operator's work efficiency. The component mounting line described in Patent Document 1 mentioned above can transmit shutdown instructions from a tablet computer to multiple devices all at once, but does not take into consideration preparations before shutdown.

[0011] According to the component mounting system described in (1) above, an operator can issue a pre-preparation instruction on any of the devices equipped with an operation unit, thereby collectively instructing multiple devices that require pre-preparation to perform the pre-preparation. This reduces the time required to issue an instruction compared to issuing instructions individually for each device. According to the component mounting system described in (1) above, after issuing a pre-preparation instruction, the operator moves to each device and shuts it down individually. However, because each device finishes pre-preparation at roughly the same timing, the operator's waiting time is only the time it takes for pre-preparation to be executed once. This reduces waiting time loss compared to when waiting time occurs for each device. Alternatively, because the operator only needs to move in one direction between devices, travel time loss can be reduced compared to traveling back and forth. It is also possible to configure the system so that all devices are instructed to shut down at once after the preparatory work is completed. In this case, the operator only has to wait for the time it takes for the preparatory work to be performed once, thereby reducing the waiting time loss. Therefore, according to the component mounting system described in (1) above, the operator's work efficiency is improved when performing shutdown preparations on multiple devices that make up a component mounting line and then shutting down those devices. Furthermore, according to the component mounting system described in (1) above, the devices constituting the component mounting line receive preparatory instructions from the operator, so there is no need for an external device such as the tablet computer of Patent Document 1. This makes it possible to improve the operator's work efficiency with a simple configuration.

[0012] (2) In the component mounting system described in (1) above, when the device equipped with the operation unit receives the pre-preparation instruction, it may further receive a specification of an operation to be performed as pre-preparation, and instruct at least one other device to perform the specified operation as pre-preparation, and the device that received the pre-preparation instruction from the operator and at least one other device that has been instructed by the device to perform the pre-preparation may perform the specified operation as pre-preparation.

[0013] Devices may be shut down for a variety of reasons, and the actions taken to prepare for the shutdown may differ depending on the purpose of the shutdown. According to the component mounting system described above in (2), the operator can specify the operations to be performed as preparations, and by specifying the operations according to the purpose of the shutdown, the operations according to the purpose of the shutdown can be performed.

[0014] (3) In the component mounting system described in (2) above, the device equipped with the operation unit may accept a selection of whether to specify the operations to be performed as the preparations collectively for multiple devices or individually for each device, and if specifying collectively is selected, accept the selection of the operations to be performed as the preparations collectively, and if specifying individually is selected, accept the selection of the operations to be performed as the preparations for each device.

[0015] When shutting down multiple devices for the same purpose, the same operations are executed as preparations for each device, which places a burden on the operator if the same operations must be specified for each device. According to the component mounting system described in (3) above, the operator can collectively specify the operations to be executed as preparations for a plurality of devices, thereby reducing the burden on the operator. However, the purpose of shutdown may differ depending on the device. According to the component mounting system described in (3) above, the operator can specify the operation to be executed as preparation for shutdown for each device by selecting "individually." Therefore, when the purpose of shutdown differs depending on the device, the operation according to the purpose of each device can be executed.

[0016] (4) In the component mounting system described in (2) or (3) above, the operation unit has a display device, and when the device equipped with the operation unit accepts a specification of an operation to be performed as the preparation, the device may display a default operation to be performed as the preparation on the display device and accept changes to the displayed operation.

[0017] According to the component mounting system described in (4) above, a default action to be performed as preparation is displayed, so if the default action corresponds to the purpose of the shutdown, the operator does not need to change the displayed action. This improves operator convenience. If the default action does not correspond to the purpose of the shutdown, the operator can change it to an action that corresponds to the purpose, thereby executing an action that corresponds to the purpose.

[0018] (5) In the component mounting system described in (4) above, the device equipped with the operation unit may, when accepting the pre-preparation instruction, accept a designation of the purpose of shutdown from the operator and switch default operation according to the designated purpose.

[0019] If an action for a specific purpose is displayed as the default action, the operator must change the displayed default action to another action if the shutdown purpose is different. For example, if actions are specified individually for multiple devices, and shutdowns are performed for different purposes, the operator must change the action to a different one for each device, which is a burden for the operator. According to the component mounting system described in (5) above, the default operation is switched depending on the specified purpose, so that the operator can specify the purpose of shutdown and have the operation corresponding to the purpose displayed as the default operation, thereby improving convenience for the operator.

[0020] (6) In the component mounting system described in (4) above, the purpose of shutdown of the device includes a normal shutdown in which the device is stopped for less than a predetermined time, and a long-term shutdown in which the device is stopped for more than the predetermined time, and when the device equipped with the operation unit receives the pre-preparation instruction, it may automatically determine whether the purpose of the shutdown is a normal shutdown or a long-term shutdown based on the production plan for the board, and switch default operation depending on the determined purpose.

[0021] According to the component mounting system described in (6) above, the purpose of the shutdown is automatically determined based on the production plan, eliminating the need for the operator to specify the purpose of the shutdown. This improves operator convenience. Since the operator does not need to determine the purpose of the shutdown, it also reduces the chance of operator misjudgment.

[0022] (7) A component mounting system according to any one of (1) to (3) above, wherein the device is equipped with a movable part, and the device equipped with the operation part, when accepting the pre-preparation instruction, accepts from the operator a designation as to whether the purpose of the shutdown is maintenance or not, and if the purpose is maintenance, further accepts a designation of a destination of the movable part, and the operation to be performed as pre-preparation when the purpose of the shutdown is not maintenance may be an operation to move the movable part to an origin position, and the operation to be performed as pre-preparation when the purpose of the shutdown is maintenance may be an operation to move the movable part to the designated destination.

[0023] Typically, maintenance of a device is performed with the device shut down. If the operation performed as preparation for shutdown is to move a moving part to its home position, the moving part will be in the home position when the device is shut down. However, if the moving part is in the home position, it may interfere with maintenance. According to the component mounting system described in (7) above, if the purpose of shutdown is maintenance, the designation of the destination of the moving part is accepted, and the operator can reduce the possibility of the moving part getting in the way when performing maintenance on the device by designating a destination other than the origin position (in other words, a destination that does not get in the way of maintenance). Therefore, if there is a plan to perform maintenance on the device while the device is shut down, the maintenance plan can be accommodated by selecting maintenance.

[0024] (8) A component mounting system according to an embodiment is a component mounting system comprising a component mounting line in which a plurality of devices for mounting components onto a substrate are arranged along a transport path of the substrate, and a management device, wherein the devices and the management device are provided with a communication unit, and the management device is provided with an operation unit that receives a pre-preparation instruction for shutdown from an operator, and when the operation unit receives the pre-preparation instruction, it instructs at least two of the devices to perform pre-preparation for shutdown, and when the at least two devices are instructed by the management device to perform the pre-preparation, they perform the pre-preparation.

[0025] According to the component mounting system described in (8) above, the operator's work efficiency is improved when making multiple devices that make up a component mounting line perform shutdown preparations and then shutting down those devices.

[0026] (9) A management method according to an embodiment is a management method for a component mounting system having a component mounting line in which a plurality of devices for mounting components on a board are arranged along a transport path of the board, and includes the steps of: one of the plurality of devices receiving a pre-preparation instruction for shutdown from an operator via an operation unit; the device that has received the pre-preparation instruction from the operator instructing at least one other device to perform the pre-preparation via a communication unit; and the device that has received the pre-preparation instruction from the operator and at least one other device that has been instructed by the device to perform the pre-preparation each performing pre-preparation for shutdown.

[0027] According to the management method described in (9) above, the operator's work efficiency is improved when a plurality of devices constituting a component mounting line are made to perform pre-shutdown preparations before shutting down those devices.

[0028] (10) A management method according to an embodiment is a management method for a component mounting system including a component mounting line in which a plurality of devices for mounting components on a board are arranged along a transport path of the board, and a management device, and includes the steps of: the management device receiving a pre-shutdown preparation instruction from an operator via an operation unit; the management device receiving the pre-shutdown preparation instruction from the operator instructing at least two of the devices to perform pre-shutdown preparation via a communication unit; and the at least two devices instructed by the management device to perform the pre-shutdown preparation carrying out the pre-shutdown preparation.

[0029] According to the management method described in (10) above, the operator's work efficiency is improved when a plurality of devices constituting a component mounting line are made to perform pre-shutdown preparations before shutting down those devices.

[0051] The arithmetic processing unit 60A includes a CPU, a RAM, etc., and controls each unit of the component mounting apparatus 15 by executing a control program stored in the storage unit 60C. The motor control unit 60B controls the rotation of each motor such as the X-axis servo motor 44 and the Y-axis servo motor 45 under the control of the arithmetic processing unit 60A. The storage unit 60C stores various programs and data executed by the calculation processing unit 60A. The data stored in the storage unit 60C includes component mounting data in which the target mounting position, target mounting angle, mounting order, etc. of each component E are set.

[0052] The image processing unit 60D is configured to take in image signals output from the component imaging camera 36 and the board imaging camera 37. The external input / output unit 60E is a so-called interface, and is configured to take in detection signals output from various sensors 65 provided in the main body of the component mounting device 15. Furthermore, the external input / output unit 60E is configured to perform operation control on various actuators 66 (such as the air supply device, the lifting mechanism 40E of the backup device 40, and the cart clamping mechanism 50) based on control signals output from the arithmetic processing unit 60A.

[0053] The feeder communication unit 60F is connected to the tape feeder 33A and controls the tape feeder 33A in an integrated manner. The communication unit 60G is a communication circuit for connecting the component mounting apparatus 15 to the communication network 5.

[0054] As shown in FIG. 2, the operation unit 61 includes a display device 61A such as a liquid crystal display, a drive circuit for driving the display device 61A, and input devices such as a touch panel and various operation buttons (emergency stop button 61B and breaker switch 61C). The emergency stop button 61B is a switch that turns on / off the power supply to the main circuit of the component mounting device 15. In the following explanation, pressing the emergency stop button 61B to turn off the power supply to the main circuit while power is being supplied to the component mounting device 15 is referred to as shutdown.

[0055] The breaker switch 61C is a main power switch. The breaker switch 61C is configured, for example, with a relay and a switch for manually opening and closing the relay. The breaker switch 61C is provided on a power line that supplies power to the component mounting apparatus 15. When the breaker switch 61C is turned off, power is not supplied to the component mounting apparatus 15 even if the emergency stop button 61B is turned on. In the first embodiment, after the operator shuts down the component mounting apparatus 15, the operator also turns off the breaker switch 61C for safety reasons.

[0056] (4) Preparation for shutdown When shutting down the component mounting apparatus 15, the operator causes the component mounting apparatus 15 to perform preparations for shutdown, and shuts down the apparatus after the preparations are completed. Here, the preparations will be described using as examples the operation of storing the nozzle 41B attached to the mounting head 41 in the nozzle station 38, the movement of the movable parts (the conveyor belt 39, the beam 42, and the push-up shaft 40D of the backup device 40), and the unclamping of the carriage.

[0057] (4-1) Store the nozzle in the nozzle station The control unit 60 opens the shutter of the nozzle station 38 and inserts the nozzle 41B attached to the mounting head 41 into an empty storage hole in the nozzle station 38. Then, the control unit 60 closes the shutter and then raises the mounting head 41. Since the nozzle 41B cannot be removed from the nozzle station 38 while the shutter is closed, the nozzle 41B is removed from the mounting head 41. As a result, the nozzle 41B is stored in the nozzle station 38.

[0058] (4-2) Movement of moving parts Movement of the movable part includes movement to the origin position, which will be explained below, and movement for maintenance. The origin position is the default position where the movable part is located when the component mounting device 15 is shut down. As will be explained in detail later, when issuing a preparation instruction, the operator specifies whether the purpose of the shutdown is maintenance or not. If the purpose of the shutdown is not maintenance, the component mounting device 15 executes movement to the origin position as preparation, and if the purpose is maintenance, it executes movement for maintenance.

[0059] (4-2-1) Origin position movement The origin position of the movable part will be described with reference to FIG. 7. The origin position of the conveyor belt 39 is represented by the conveyor width. The conveyor width is the width between the front conveyor belt 39A and the rear conveyor belt 39B, and the origin position is at its maximum. "Maximum" means that the front conveyor belt 39A is at the frontmost position and the rear conveyor belt 39B is at the rearmost position. The origin position of the beam 42 is the frontmost position for the front beam 42 and the rearmost position for the rear beam 42. The origin position of the push-up shaft 40D of the backup device 40 is at its lowermost position (the position where the push-up shaft 40D is at its lowest position). These origin positions are merely examples. The origin position is not limited to these and can be determined as appropriate.

[0060] (4-2-2) Movement for maintenance Movement for maintenance will be described with reference to Figure 8. Specific maintenance of the component mounting apparatus 15 includes replacing the nozzle 41B stored in the nozzle station 38, adjusting the component imaging camera 36, ​​rearranging the backup pin 40A of the backup device 40, and cleaning the nozzle shaft 41A. Various types of maintenance are performed, but are not limited to these. Because an operator must reach inside the component mounting apparatus 15 during maintenance, the operator shuts down the component mounting apparatus 15 for safety reasons and turns off the breaker switch 61C.

[0061] When performing maintenance on the component mounting device 15, if the moving parts are in the home position, they may get in the way of the maintenance. For example, when performing maintenance on the component imaging camera 36, ​​if the head unit 34 or conveyor belt 39 are in the home position, they may get in the way and make the work difficult. When replacing the nozzle 41B stored in the nozzle station 38, if the head unit 34 or conveyor belt 39 are in the home position, they may get in the way and make the work difficult. When rearranging the backup pin 40A, if the push-up shaft 40D is in the home position (i.e., the lowest position), it may be difficult to reach the backup pin 40A, which may reduce workability. Therefore, if the purpose of the shutdown is maintenance, the component mounting device 15 receives a designation of the destination of these devices and moves these devices to the designated destination.

[0062] (4-3) Unclamping the cart Carriage unclamping will be described with reference to Figures 5A, 5B, and 5C. Carriage unclamping is an operation for raising the lifting section 50B of the carriage clamping mechanism 50 so that the carriage 55A of the tape component supply device 33 can be removed. For example, when the component mounting device 15 is stopped (in other words, shut down), an operator may replace the nozzle 41B stored in the nozzle station 38. In this case, if the tape component supply device 33 remains set, it may get in the way of replacing the nozzle 41B. Removing the carriage 55A makes it easier to replace the nozzle 41B.

[0063] In the first embodiment, if the component mounting apparatus 15 is stopped for a long period of time, the supply of air to the air cylinder of the cart clamping mechanism 50 is stopped. If the system is shut down while the cart 55A is clamped, the lifting unit 50B cannot be raised because the air supply has been stopped, making it impossible to remove the cart 55A. If the component mounting apparatus 15 is stopped for a long period of time, performing cart unclamping as preparation makes it possible to remove the cart 55A while the component mounting apparatus 15 is stopped.

[0064] (5) A user interface for instructing the execution of preparatory work The operator can issue a shutdown preparation instruction by operating the operation unit 61 of any of the component mounting apparatuses 15, thereby collectively instructing all of the component mounting apparatuses 15 constituting the component mounting line 10 to execute shutdown preparation. In the first embodiment, the operator can issue a preparation instruction from any of the component mounting apparatuses 15.

[0065] When the component mounting apparatus 15 according to the first embodiment accepts a preparation instruction, it further accepts designation of an operation to be executed as preparation, and instructs all other component mounting apparatuses 15 to execute the designated operation as preparation. Then, the component mounting apparatus 15 that accepted the preparation instruction from the operator, and all other component mounting apparatuses 15 that have been instructed by the component mounting apparatus 15 to execute preparation, execute the designated operation as preparation.

[0066] 9, an explanation will be given of the operation screen 70 that receives various settings and operation instructions from the operator for the component mounting apparatus 15. The operation screen 70 is a screen that is displayed on the display device 61A. A preparation button 70A for instructing the execution of preparations for shutdown is displayed on the operation screen 70.

[0067] When the operator presses the preparation button 70A, the control unit 60 displays the line operation execution screen 71 shown in Fig. 10. The line operation execution screen 71 is a screen on which the operator can specify the purpose of shutdown, the operations to be performed as preparation, etc. On the line operation execution screen 71, the operator can select (an example of specification) setting values ​​for the following three setting fields:

[0068] · Bulk / individual setting field 71A The collective / individual setting field 71A is a setting field for the operator to select whether to specify the operation to be executed as preparation for shutdown for all component mounting devices 15 collectively, or to specify the operation individually for each component mounting device 15. The display content of the operation setting field 71C, which will be described later, differs depending on whether collective or individual is selected. Fig. 10 shows the display content when collective is selected. The display content when individual is selected will be described later.

[0069] Shutdown purpose setting field 71B There are various purposes for shutting down. In the first embodiment, the following three purposes can be selected as the purpose for shutting down.

[0070] Shutdown Purpose 1: Shutdown (Normal) Shutdown (normal) is a shutdown in which the component mounting apparatus 15 has been stopped for less than a predetermined time (for example, 24 hours). When the component mounting apparatus 15 finishes operation for one day and continues to operate the next day, the component mounting apparatus 15 has been stopped for less than 24 hours. Therefore, in this case, shutdown (normal) is selected as the purpose of shutdown. Shutdown (normal) is an example of a normal shutdown. Shutdown (normal) is displayed as the default in the shutdown purpose setting field 71B.

[0071] Shutdown purpose 2: Shutdown (long-term stop) A shutdown (long-term shutdown) is a shutdown in which the component mounting apparatus 15 is stopped for a predetermined period of time (for example, 24 hours) or longer. When the component mounting apparatus 15 is stopped for a long period of time, such as on a weekend or a long vacation, the component mounting apparatus 15 is stopped for 24 hours or longer. Therefore, in this case, a shutdown (long-term shutdown) is selected as the purpose of the shutdown. A shutdown (long-term shutdown) is an example of a long-term shutdown.

[0072] Shutdown Purpose 3: Maintenance Maintenance is the shutdown for the maintenance mentioned above. The content displayed when Maintenance is selected will be described later.

[0073] Even when "individual" is selected in the collective / individual setting field 71A, the shutdown purpose is uniformly applied to all component mounting devices 15. That is, in the first embodiment, even if "individual" is selected in the collective / individual setting field 71A, the shutdown purpose cannot be individually selected.

[0074] ·Operation setting field 71C When accepting the selection of an operation to be performed as preparation, the component mounting apparatus 15 according to the first embodiment displays a default operation to be performed as preparation in the operation setting field 71C. When displaying the default operation, the component mounting apparatus 15 switches the default operation depending on the shutdown purpose selected in the shutdown purpose setting field 71B. Specifically, if the stop time of the component mounting device 15 is short, the supply of air to the air cylinder is not stopped, and therefore, if necessary, it is possible to supply power to the component mounting device 15 after shutdown and unclamp the cart 55A. Therefore, if the stop time is short, it is not necessary to unclamp the cart 55A. For this reason, as shown in FIG. 10, in the case of shutdown (normal), "Yes" is displayed by default for the origin position movement in the operation setting field 71C, and "No" is displayed by default for cart unclamping. The display of the default operation when shutdown (long-term stop) is selected and the display of the default operation when maintenance is selected will be described later.

[0075] The operator can change the displayed default action to another action. For example, if a shutdown (normal) is selected and the operator also wants to unclamp the carriage as preparation, the operator can change the unclamp carriage to "Yes."

[0076] 11 and 12, the display content when "individual" is selected in the collective / individual setting field 71A will be described. Fig. 11 shows a case where "individual" is selected in the collective / individual setting field 71A and "shutdown (normal)" is selected in the shutdown purpose setting field 71B. When "individual" is selected, the default operation to be performed as preparation is displayed for each device number of the component mounting device 15. For example, in the case of shutdown (normal), "Yes" is displayed by default for moving the origin position and "No" is displayed by default for unclamping the carriage for each device number.

[0077] As mentioned above, the operator can change the operation. For example, if the operator changes the carriage unclamping of the component mounting device 15 with device number 4 to "Yes," the component mounting device 15 with device number 4 will perform both origin position movement and carriage unclamping as preparations.

[0078] 12, the display content when "individual" is selected in the collective / individual setting field 71A and "shutdown (long-term stop)" is selected in the shutdown purpose setting field 71B will be described. As mentioned above, if the component mounting device 15 is stopped for a long time, the supply of air to the air cylinder of the cart clamping mechanism 50 is stopped, and therefore cart 55A cannot be removed unless it is unclamped. For this reason, in the case of shutdown (long-term stop), "Yes" is displayed by default for moving to origin position, and "Yes" is also displayed by default for cart unclamping.

[0079] With reference to Figure 13, the display content when maintenance is selected in the shutdown purpose setting field 71B will be described. The example shown in Figure 13 shows a case where individual is selected in the collective / individual setting field 71A and maintenance is selected in the shutdown purpose setting field 71B. When the shutdown purpose is maintenance, if the operator sets the origin position movement to "no" for any device, the destination of the moving part for that device can be selected. If the origin position movement is set to "yes," the destination cannot be selected.

[0080] For the beam position, the back (rear side in the Y direction), front (front side in the Y direction), or center (center in the Y direction) can be selected as the movement destination of the beam 42 in the Y direction. Back is a state in which the two beams 42 are positioned at the rearmost position within their respective movable ranges. Center is a state in which the two beams 42 are positioned near the center in the front-to-rear direction. Front is a state in which the two beams 42 are positioned at the frontmost position within their respective movable ranges. Back is displayed as the default beam position.

[0081] For the conveyor width, you can select maximum or minimum. At maximum, the front conveyor belt 39A moves to the frontmost position, and the rear conveyor belt 39B moves to the rearmost position. At minimum, the distance between the front conveyor belt 39A and the rear conveyor belt 39B is the narrowest. Maximum is displayed as the default conveyor width.

[0082] For the push-up axis, you can select either down or up. Down is when the push-up axis 40D is at its lowest position, and up is when the push-up axis 40D is at its highest position. Down is displayed as the default for the push-up axis 40D.

[0083] If the moving part is in the home position and would interfere with maintenance, the operator selects a destination other than the home position (a destination that does not interfere with maintenance) for the moving part that is interfering with maintenance. This makes it possible to prevent the moving part from interfering with maintenance.

[0084] After selecting the setting values ​​in the three setting fields described above, the operator selects "Yes" on the line operation execution screen 71. When "Yes" is selected, the component mounting device 15 accepts the pre-preparation instruction. The component mounting device 15 that has accepted the pre-preparation instruction instructs all other component mounting devices 15 to execute the operation selected on the line operation execution screen 71 as pre-preparation.

[0085] The process described below is common to the component mounting apparatus 15 to which the operator has issued a pre-preparation instruction and to another component mounting apparatus 15 to which the operator has issued a pre-preparation instruction from that component mounting apparatus 15. When the component mounting apparatus 15 is instructed to execute pre-preparation, it executes the specified operation as pre-preparation. As shown in Fig. 14, the component mounting apparatus 15 displays a processing screen 72 while the pre-preparation is being executed. The processing screen 72 displays the progress of the pre-preparation.

[0086] 15, when the component mounting apparatus 15 has completed the preparations, it displays a confirmation screen 73 that guides the operator to press the emergency stop button 61B. Since the emergency stop button 61B is a physical button that is manually operated, the operator moves to each component mounting apparatus 15 and presses the emergency stop button 61B individually. In the first embodiment, after pressing the emergency stop button 61B, the operator also turns off the breaker switch 61C.

[0087] (6) Shutdown flow With reference to FIG. 16, an operation in which an operator issues a preparatory instruction in any one of the component mounting apparatuses 15 and a flow of shutdown executed by the control unit 60 of the component mounting apparatus 15 will be described.

[0088] In S101, the operator moves to any one of the component mounting apparatuses 15 and presses the preparation button 70A on the operation screen 70. When the operator presses the preparation button 70A, the line operation execution screen 71 is displayed. In S102, the operator selects a preparatory action for shutdown on the line operation execution screen 71. After selecting the preparatory action, the operator selects "Yes" or "No."

[0089] In S103, if "Yes" is selected on the line operation execution screen 71, the control unit 60 proceeds to S104, and if "No" is selected, the control unit 60 ends the process. In S104, the control unit 60 instructs all other component mounting apparatuses 15 via the communication unit 60G to execute the operation selected on the line operation execution screen 71 as preparation for shutdown.

[0090] In S105, the control unit 60 starts preparations for shutdown. During the preparations, the control unit 60 displays a processing screen 72 shown in FIG. In S106, the control unit 60 determines whether or not the preparation is complete. If it is complete, the process proceeds to S107, and if it is not complete, the control unit 60 executes S106 again after a predetermined time has elapsed.

[0091] In S107, the control unit 60 displays a confirmation screen 73 shown in FIG. 15 to guide the operator to press the emergency stop button 61B. In S108, the operator presses the emergency stop button 61B. In S109, the operator turns off the breaker switch 61C.

[0092] The shutdown flow executed by the control unit 60 of the other component mounting apparatus 15 will be described with reference to Fig. 17. The shutdown flow shown in Fig. 17 is executed on the premise that the other component mounting apparatus 15 is in an operation stop state. When the other component mounting apparatus 15 is instructed to execute preparations for shutdown in S104 described above, it executes S105 to S109 as shown in Fig. 17. The processing of S105 to S109 is substantially the same as the processing of S105 to S109 shown in Fig. 16, and therefore description thereof will be omitted.

[0093] (7) Effects of the embodiment According to the component mounting system 1 according to the first embodiment, an operator can collectively instruct a plurality of component mounting apparatuses 15 to perform preparation by issuing a preparation instruction to any one of the component mounting apparatuses 15. This reduces the time required to issue an instruction compared to issuing an instruction to each component mounting apparatus 15 individually. According to the component mounting system 1, after issuing a pre-preparation instruction, the operator moves to each component mounting device 15 and presses the emergency stop button 61B individually. However, because each component mounting device 15 finishes pre-preparation at roughly the same timing, the operator's waiting time is only the time it takes for pre-preparation to be executed once. This reduces waiting time loss compared to when waiting time occurs for each component mounting device 15. Alternatively, because the operator only needs to move in one direction between component mounting devices 15, the operator can reduce travel time loss compared to traveling back and forth. Therefore, according to the component mounting system 1, the operator's work efficiency is improved when shutting down multiple component mounting devices 15 that make up the component mounting line 10 after having them perform shutdown preparations. Furthermore, according to the component mounting system 1, the component mounting device 15 receives preparation instructions from the operator, so there is no need for an external device such as the tablet computer of Patent Document 1. This makes it possible to improve the operator's work efficiency with a simple configuration.

[0094] According to component mounting system 1, the operator can specify the operations to be performed as preparations (for example, whether or not to move the origin position, whether or not to unclamp the carriage), and by specifying the operations according to the purpose of shutdown, the operations according to the purpose of shutdown can be executed.

[0095] According to the component mounting system 1, the operator can specify the operation to be executed as preparation for multiple component mounting apparatuses 15 at once by selecting "all at once" in the all at once / individual setting field 71A. This reduces the burden on the operator. However, the purpose of shutdown may differ depending on the component mounting apparatus 15. According to the component mounting system 1, the operator can select the operation to be executed as preparation for shutdown for each component mounting apparatus 15 by selecting "individual." Therefore, if the purpose of shutdown differs depending on the component mounting apparatus 15, it is possible to execute an operation according to the purpose for each component mounting apparatus 15.

[0096] According to the component mounting system 1, a default action to be executed as preparation is displayed, so if the default action corresponds to the purpose of the shutdown, the operator does not need to change the displayed action. This improves operator convenience. If the default action does not correspond to the purpose of the shutdown, the operator can change it to an action that corresponds to the purpose, thereby executing an action that corresponds to the purpose.

[0097] According to the component mounting system 1, the line operation execution screen 71 switches and displays default actions according to the specified purpose, so that the operator can specify the purpose of shutdown and have the action according to the purpose displayed as the default action, thereby improving convenience for the operator.

[0098] According to the component mounting system 1, if the purpose of shutdown is maintenance, specification of the destination of the movable part is accepted, and by specifying a destination other than the origin position as the destination (in other words, a destination that does not interfere with maintenance), the operator can reduce the possibility that the movable part will get in the way when performing maintenance on the component mounting device 15. Therefore, if there is a plan to perform maintenance on the component mounting device 15 while the component mounting device 15 is shut down, the maintenance plan can be accommodated by selecting maintenance.

[0099] <Embodiment 2> The component mounting apparatus 15 according to the second embodiment automatically determines whether the purpose of the shutdown is a shutdown (normal) or a shutdown (long-term stop) based on the production plan for the board P, and switches the default operation according to the determined purpose.

[0100] The production plan for board P will be described with reference to Figure 18. In Figure 18, the start date is the date on which board P will be produced, and the start time is the time when production of board P will begin. The production model name is the model name of the board P to be produced. When the preparation button 70A is pressed on the operation screen 70, the control unit 60 obtains the date and time when the next production will start from the production plan and determines whether the stoppage time from when the preparation button 70A was pressed to when the next production will start is equal to or longer than a predetermined time. Then, when displaying the line operation execution screen 71, the control unit 60 automatically selects shutdown (normal) as the shutdown purpose if the predetermined time is less than the predetermined time, and displays the default action for shutdown (normal). If the predetermined time is equal to or longer than the predetermined time, the control unit 60 automatically selects shutdown (long-term shutdown) as the shutdown purpose and displays the default action for shutdown (long-term shutdown).

[0101] For example, suppose production ends at 17:00 on August 11, 2022, and the operator presses the preparatory button 70A. In this case, the next production will start at 8:00 on August 12, 2022, so the downtime from when the preparatory button 70A is pressed to when the next production will start is 15 hours. In this case, if the predetermined time is 24 hours, shutdown (normal) is selected because it is less than the predetermined time.

[0102] In contrast, suppose production ends at 17:00 on August 12, 2022, and the operator presses the preparatory button 70A. In this case, the next production will start at 8:00 on August 17, 2022, so the downtime from when the preparatory button 70A is pressed to when the next production will start is 111 hours. In this case, if the predetermined time is 24 hours, this is longer than the predetermined time, so shutdown (long-term shutdown) is selected.

[0103] According to the component mounting system 1 of the second embodiment, the purpose of the shutdown is automatically determined based on the production plan, so the operator does not have to go through the trouble of selecting the purpose of the shutdown. This improves operator convenience. Since the operator does not have to determine whether the purpose of the shutdown is a shutdown (normal) or a shutdown (long-term stop), it also helps to reduce operator errors in judgment.

[0104] <Embodiment 3> 19, a component mounting system 201 according to the third embodiment includes a component mounting line 10 and a management device 90. The management device 90 is a so-called personal computer. The management device 90 includes a control unit, a storage unit, a display unit (such as a liquid crystal display), an operation unit (such as a keyboard, a mouse, or a touch panel), and a communication unit, and is connected to a communication network 5 via the communication unit. In the third embodiment, each device constituting the component mounting line 10 communicates with the other devices via the management device 90.

[0105] In the third embodiment, the component mounting apparatus 15 that has received the pre-preparation instruction notifies the management apparatus 90 via the communication unit 60G that the pre-preparation instruction has been received. When the management apparatus 90 is notified that the pre-preparation instruction has been received, it instructs all other component mounting apparatuses 15 to perform pre-preparation. In other words, the component mounting apparatus 15 that has received the pre-preparation instruction indirectly instructs the other component mounting apparatuses 15 to perform pre-preparation via the management apparatus 90.

[0106] <Embodiment 4> The configuration of the component mounting system according to the fourth embodiment is substantially the same as that of the third embodiment. In the fourth embodiment, the management device 90 receives a pre-preparation instruction from an operator and instructs each component mounting device 15 to execute pre-preparation for shutdown. Each component mounting device 15 that has been instructed to execute pre-preparation executes its own pre-preparation.

[0107] According to the component mounting system 1 of embodiment 4, the operator's work efficiency is improved when performing shutdown preparations on multiple component mounting devices 15 that make up the component mounting line 10 and then shutting down those component mounting devices 15.

[0108] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and in the drawings, and for example, the following embodiments are also included in the technical scope disclosed in this specification.

[0109] (1) In the above embodiment, the conveyor belt 39, the beam 42, and the push-up shaft 40D of the backup device 40 are exemplified as movable parts, but the movable part is not limited to these. For example, the movable part may be the head unit 34. In this case, the origin position of the head unit 34 may be the rightmost side (upstream side) or the leftmost side (downstream side) of the movable range in the X direction.

[0110] (2) In the above embodiment, the case where the purpose of shutdown cannot be individually selected even if "Individual" is selected in the collective / individual setting field 71A has been exemplified. In contrast, when "Individual" is set, the purpose of shutdown may also be individually set.

[0111] (3) In the above embodiment, the component mounting apparatuses 15 are used as an example of the plurality of apparatuses. However, the plurality of apparatuses is not limited to the component mounting apparatuses 15 as long as they are apparatuses that make up the component mounting line 10.

[0112] (4) In the above embodiment, the component mounting system 1 includes one component mounting line 10, but the component mounting system 1 may include two or more component mounting lines 10. When a device on one of the component mounting lines 10 receives a pre-preparation instruction from an operator, the device may instruct not only other devices constituting the component mounting line 10 but also devices constituting the other component mounting lines 10 to perform pre-preparation.

[0113] (5) In the above embodiment, an example was given in which the operator went to each component mounting apparatus 15 and pressed the emergency stop button 61B after the component mounting apparatus 15 had completed preparations. However, a configuration in which each component mounting apparatus 15 was shut down collectively may also be used. For example, if a power line connected to a commercial power source branches off midway and is connected to each component mounting apparatus 15, an emergency stop button 61B may be provided on the power line before the branch, and pressing the emergency stop button 61B may simultaneously cut off the power supply to each component mounting apparatus 15. In this case, after the operator has completed preparations at each component mounting apparatus 15, the operator presses the emergency stop button 61B to simultaneously cut off the power supply to each component mounting apparatus 15. In this case, the operator's waiting time is only the time required for one preparation run, thereby reducing waiting time loss and improving operator work efficiency compared to when the operator went to each component mounting apparatus 15 and shut down each apparatus individually.

[0114] (6) In the above embodiment, an example was given in which the operator can issue a pre-preparation instruction from any component mounting apparatus 15. However, the component mounting apparatuses 15 to which the operator can issue a pre-preparation instruction may be limited to specific component mounting apparatuses 15.

[0115] (7) In the fourth embodiment, a personal computer is used as the management device 90, but the management device 90 is not limited to a personal computer. For example, the management device 90 may be a tablet computer that is wirelessly connected to the communication network 5. [Explanation of symbols]
