The lower end of the mounting head 331 that is not engaged with the nozzle N is pushed into the nozzle N held in the nozzle storage hole 371 of the nozzle stocker 37, so that the mounting head 331 is engaged with the nozzle N. The engagement between the mounting head 331 and the nozzle N is held by an elastic force such as a leaf spring. Further, the mounting head 331 is raised while the shutter of the nozzle stocker 37 is open, so that the nozzle N engaged with the mounting head 331 is removed from the nozzle storage hole 371 of the nozzle stocker 37 (nozzle attachment). On the other hand, with the shutter of the nozzle stocker 37 open, the nozzle N engaged with the lower end of the mounting head 331 descends into the nozzle storage hole 371 of the nozzle stocker 37, whereby the nozzle N is inserted into the nozzle storage hole 371. . Subsequently, after closing the shutter of the nozzle stocker 37 , the mounting head 331 is lifted so that the lower end of the mounting head 331 is separated from the nozzle N held in the nozzle housing hole 371 , and the nozzle N is removed from the mounting head 331 . Removed (nozzle removal). The nozzle N attached to the mounting head 331 can be replaced by performing such nozzle attachment and nozzle removal in combination.

Also, the pallet P delivered from the setup device 2 toward the component mounter 3 is carried into the component mounter 3 . On the other hand, the component mounter 3 includes a pallet operation section 38 that operates the pallet P. As shown in FIG. Subsequently, the palette P and the palette operation unit 38 will be specifically described with reference to FIGS. 4A to 4D.

4A and 4B are partial cross-sectional views schematically showing the configuration of the pallet. The pallet P has a base plate 41 having a rectangular shape in plan view from the Z direction. The base plate 41 has a storage plate portion 41A provided with a plurality of nozzle storage holes 411, and conveyor mounting portions 41B provided on both sides of the storage plate portion 41A in the Y direction. The nozzle housing hole 411 passes through the base plate 41 in the Z direction and holds the nozzle N inserted from above. The storage plate portion 41A has a greater thickness than the conveyor mounting portion 41B and protrudes downward from the conveyor mounting portion 41B. The bottom surface of each conveyor mounting portion 41B is a horizontal mounting surface 41C. Conveyed by

conveyor

241 , 271 , 281 or 311 .

Further, the pallet P has a shutter 43 attached to the upper surface of the base plate 41. The shutter 43 has a plurality of engaging portions 431 corresponding to the plurality of nozzle housing holes 411 respectively. The shutter 43 is movable in the X direction with respect to the base plate 41, and is positioned at an engaging position (the position of the shutter 43 in FIG. ) and a separation position where the engaging portion 431 is separated from the nozzle N accommodated in the nozzle accommodation hole 411 . When the shutter 43 is positioned at the engagement position, the engagement portion 431 prohibits the removal of the nozzle N from the nozzle housing hole 411 (that is, the shutter 43 is closed). On the other hand, when the shutter 43 is positioned at the separated position, removal of the nozzle N from the nozzle housing hole 411 is permitted (that is, the shutter 43 is opened).

　Figs. 4C and 4D are diagrams schematically showing the configuration and operation of the pallet operation section of the component mounter. The pallet operation unit 38 has a stopper 381 , an opening/closing cylinder 382 attached to the stopper 381 , and an elevating cylinder 383 supporting the stopper 381 and the opening/closing cylinder 382 . The elevator cylinder 383 lifts and lowers the stopper 381 and the open/close cylinder 382 integrally, thereby moving them to a position overlapping the passage path of the pallet P (positions shown in FIGS. 4C and 4D) and downward from the passage path of the pallet P. Move to and from the retracted position. The passage route of the pallet P is the route through which the pallet P conveyed in the X direction by the substrate conveyor 31 passes.

With such a configuration, the pallet P can be conveyed in the X direction by the substrate conveyor 31 by retracting the stopper 381 and the opening/closing cylinder 382 from the passage path of the pallet P. On the other hand, by positioning the stopper 381 in the passage path of the pallet P, the pallet P can be stopped by bringing the stopper 381 into contact with the pallet P from the downstream side in the X direction. In addition, the pallet operation section 38 has a single-axis robot 384 that drives an elevating cylinder 383 in the X direction. This single-axis robot 384 can be composed of, for example, a linear motor or a ball screw. When the single-axis robot 384 drives the lifting cylinder 383 in the X direction, the stopper 381 and the opening/closing cylinder 382 supported by the lifting cylinder 383 move in the X direction. Therefore, the single-axis robot 384 can change the position where the pallet P is stopped by the stopper 381 .

When the stopper 381 is in contact with the pallet P, the opening/closing cylinder 382 can operate the shutter 43 . That is, by driving the shutter 43 in the X direction by the opening/closing cylinder 382, the shutter 43 is positioned at either the engaged position (the position of the shutter 43 in FIG. 4C) or the separated position (the position of the shutter 43 in FIG. 4D). can. The opening/closing cylinder 382 can drive the shutter 43 while gripping the shutter 43 by magnetic force, for example. According to the pallet P, the nozzles N can be attached to and detached from the mounting head 331 in the same manner as the nozzle stocker 37 described above.

That is, the nozzle N is engaged with the mounting head 331 by pushing the lower end of the mounting head 331 that is not engaged with the nozzle N into the nozzle N held in the nozzle housing hole 411 of the pallet P. Further, when the mounting head 331 is lifted while the shutter 43 of the pallet P is open (that is, positioned at the separated position), the nozzles N engaged with the mounting head 331 move out of the nozzle storage holes 411 of the pallet P. Taken out (nozzle attachment). On the other hand, when the shutter 43 of the pallet P is open, the nozzle N engaged with the lower end of the mounting head 331 descends into the nozzle storage hole 411 of the pallet P, whereby the nozzle N is inserted into the nozzle storage hole 411 . Subsequently, after the nozzle housing holes 411 of the pallet P are closed (that is, after the mounting head 331 is positioned at the engaging position), the mounting head 331 is lifted from the nozzles N held in the nozzle housing holes 411 to the mounting head 331 . is released, and the nozzle N is removed from the mounting head 331 (nozzle removal). In such a component mounter 3 , the movement of the nozzle N between the nozzle stocker 37 and the pallet P can be executed by cooperation between the mounting head 331 and the pallet operation section 38 .

In such a configuration, as shown in FIG. 1, the delivery conveyor 27 of the setup device 2 and the board conveyor 31 of each component mounter 3 belonging to the same board production line L are arranged in series to transport one board. compose a line. Therefore, the pallets P carried out from the unloading conveyor 27 by the setup device 2 can be carried into the plurality of component mounters 3 in order. Specifically, a transport mode as shown in FIGS. 5A to 5D below can be executed. Each transport mode shown below is a part of all transport modes that can be executed in the board production line L, and the board production line L can transport the pallet P in other transport modes.

　FIGS. 5A to 5D are diagrams schematically showing an example of a pallet transport mode that can be executed on a substrate production line. 5A to 5D, the delivery conveyor 27 and the board conveyor 31 adjacent to each other are simply represented by a pair of belt conveyors, and the two board conveyors 31 adjacent to each other are simply represented by a pair of belt conveyors. Expressed on a conveyor belt.

In the transport mode of FIG. 5A, one pallet P is transported to each of a plurality of component mounters 3. That is, the pallets P are sequentially transported from the downstream side in the X direction among the plurality of component mounters 3 arranged in series in the X direction. Specifically, in steps S<b>21 and S<b>22 , the pallet P is conveyed from the setup device 2 to the most downstream component mounter 3 among the plurality of component mounters 3 . Next, in steps S23 and S24, the pallet P is conveyed from the setup device 2 to the most downstream component mounter 3 in the X direction among the component mounters 3 to which the pallet P has not yet been carried. By repeating the transport of the pallet P in the same manner, the pallet P is transported to each of the plurality of component mounters 3 as shown in step S25.

In the transport mode of FIG. 5B, the number of pallets P is smaller than the number of component mounters 3 to which pallets P are transported, and one pallet P is transported to two component mounters 3 . Specifically, in step S31, the pallet P is conveyed from the setup device 2 to an odd-numbered component mounter 3 counted from the upstream side in the X direction. In the next step S32, each pallet P is conveyed from the odd-numbered component mounters 3 to the even-numbered component mounters 3 by being conveyed downstream in the X direction.

In the transport mode of FIG. 5C, the number of pallets P is smaller than the number of component mounters 3 to which pallets P are transported, and one pallet P is transported to a plurality of component mounters 3 in order. Specifically, the pallet P carried out from the setup device 2 to the downstream side in the X direction is sequentially conveyed from the component mounter 3 on the upstream side in the X direction among the plurality of component mounters 3 (steps S41 to S45).

In the transport mode of FIG. 5D, the number of pallets P is smaller than the number of component mounters 3 to which pallets P are transported, and one pallet P is transported to a plurality of component mounters 3 in order. Specifically, the pallet P is conveyed to the most downstream component mounter 3 in the X direction among the plurality of component mounters 3 (steps S51 and S52). Next, the pallet P is conveyed in order from the component mounter 3 on the downstream side in the X direction (steps S52 to S55).

"In addition, in the above." A case of transporting a pallet P from a setup device 2 to a component mounter 3 is described. However, by transporting the pallet P from each component mounter 3 toward the setup device 2 , the pallet P transported to the component mounter 3 can be recovered to the setup device 2 .

In each board production line L of the component mounting system 1 described above, the setup device 2 places the nozzles N used for component mounting on the board B on the pallet P and delivers them to the component mounter 3 . can be done. Then, the component mounter 3 can receive the nozzle N delivered from the setup device 2 by taking it out from the pallet P with the mounting head 331 (receiving operation). In such a receiving operation, the nozzles N placed on the pallet P can be moved to the nozzle stocker 37 and the nozzles N placed on the pallet P can be attached to the mounting head 331 . Therefore, in this embodiment, the nozzle N used for component mounting is set up by the component mounter 3 by delivering the nozzle N from the setup device 2 to the component mounter 3 . In particular, this setup is managed by sending commands from the server computer 100 to the setup device 2 .

FIG. 6 is a diagram showing a flowchart showing an example of a method of creating a command for a setup device, and FIG. 7 is a flowchart showing a first example of determining the shipping mode executed in the flowchart of FIG. The flowcharts of FIGS. 6 and 7 are individually executed for each of the plurality of board production lines L by the server computer 100. FIG.

　In step S61 of command creation in Fig. 6, the delivery mode determination (Fig. 7) is executed. As will be described later, delivery mode determination can be executed in a plurality of modes. Here, the basic mode of delivering nozzles N that are insufficient for component mounting to the component mounter 3 will be described.

In step S101 of FIG. 7, the computing unit 110 of the server computer 100 allocates the pallet P used for shipping the nozzles N to the plurality of mounters 3. Here, the number of pallets P that can be used for shipping the nozzle N is equal to or greater than the number of component mounters 3 to which the nozzle N is to be shipped, and one pallet P is required for one component mounter 3. An example of allocation will be used for explanation. Therefore, transportation of the pallet P to the component mounter 3 can be executed by the transportation mode of FIG. 5A described above. However, if the number of pallets P is small, one pallet P may be assigned to two or more component mounters 3, and the pallet P may be transported by the transport modes shown in FIGS. 5B to 5C. can be done.

At step S102 in FIG. 7, the calculation unit 110 confirms the nozzles N owned by the component mounter 3 and the nozzles N that the component mounter 3 plans to use for subsequent component mounting. Specifically, the possessed nozzle information shown in FIG. 8A and the intended use nozzle information shown in FIG.

FIG. 8A is a diagram showing an example of possessed nozzle information indicating the possessed nozzles of a component mounter. In the figure, a plurality of component mounters 3 are distinguished by different reference numerals 3(1) to 3(4), and the same notation will be used appropriately below. Here, the owned nozzles refer to the nozzles N stored in the nozzle stocker 37 of the component mounter 3 and the nozzles N attached to the mounting head 331 of the component mounter 3 at present. This possessed nozzle information indicates, for each nozzle N possessed by the component mounter 3, the type Nk of the nozzle N, the nozzle ID of the nozzle N, the adsorption rate of the nozzle N, and the number of shots of the nozzle N. The nozzle ID is an identifier assigned to the nozzle N to identify the nozzle N. FIG. In other words, the calculation unit 110 recognizes the nozzle ID of the nozzle N owned by the component mounter 3 by managing the nozzle ID of the nozzle N delivered to/collected from the component mounter 3 . The pickup rate is the success rate of picking up components using the nozzle N, and the number of shots is the number of times the component is mounted on the board B using the nozzle N. That is, the calculation unit 110 collects the pick-up rate and the number of shots from the mounter 3 via the communication unit 130 . Note that the pick-up rate and the number of shots are measured in the component mounter 3 and reset each time the nozzle N is cleaned, for example.

FIG. 8B is a diagram showing an example of scheduled use nozzle information indicating the scheduled use nozzles of the component mounter. This scheduled use nozzle information indicates the type Nk of each nozzle N possessed by the mounter 3 . Specifically, the storage unit 140 stores a production plan indicating the types and number of component-mounted boards (boards B on which components are mounted) to be produced on the board production line L. In the production (board production) of the component-mounted boards to be used, the nozzles N to be used by each component mounter 3 are obtained from the production plan, thereby obtaining information on nozzles to be used.

In step S103, the calculation unit 110 obtains the difference between the nozzles N indicated by the information on the nozzles to be used and the nozzles N indicated by the information on the owned nozzles. Confirm about 3. In other words, the nozzles N that are indicated in the scheduled use nozzle information but not indicated in the possessed nozzle information are the missing nozzles.

In step S104, the calculation unit 110 determines the insufficient nozzles N confirmed for the component mounter 3 as delivery target nozzles to be delivered to the component mounter 3, and creates delivery target nozzle information (FIG. 8C). ). FIG. 8C is a diagram showing a first example of delivery target nozzle information indicating nozzles to be delivered to the component mounter. The delivery target nozzle information includes the pallet ID of the pallet P to be conveyed to the component mounter 3, the type Nk of the nozzle N placed on the pallet P and delivered to the component mounter 3, and the nozzle ID of each component. Mounting machine 3 is shown. In this way, the delivery mode of the nozzle N is determined.

In step S62 of FIG. 6, a shipping preparation command for causing the setup device 2 to prepare the pallet P on which the nozzle N is placed according to the shipping target nozzle information obtained in step 104 is sent to the computing unit 110. is created by and stored in the storage unit 140 .

FIG. 9 is a flow chart showing an example of a method of creating commands for a setup device and a component mounter, and FIG. 11 is a flow chart showing a first example of recovery mode determination executed in the flow chart of FIG. The flowcharts of FIGS. 9, 10 and 11 are individually executed for each of the plurality of board production lines L by the server computer 100. FIG.

In step S71 of command creation in FIG. 9, the delivery mode determination (FIG. 10) is executed. Determining delivery mode in the selective replacement mode in which nozzles N that are insufficient for component mounting and nozzles N to be replaced for maintenance are delivered to the component mounter 3 will be described here.

Also in FIG. 10, steps S101 to S103 are executed for each mounter 3 in the same manner as in the above example. That is, pallets P are assigned to a plurality of mounters 3 (step S101). Then, based on the result of confirming the owned nozzles and the nozzles to be used in step S102, the missing nozzles N are confirmed.

In the next step S105, the calculation unit 110 determines the time (operation time) that each mounter 3 can use for the receiving operation for the nozzle N delivered from the setup device 2 based on the production plan. Specifically, the operation time to be assigned to the receiving operation is determined within a range in which the next board production can be started at the scheduled time determined in the production plan.

In step S106, the calculation unit 110 determines the number of nozzles N that can be received by the mounter 3 within the operation time determined in step S105 (receivable number). Calculate the number (maintainable number) by subtracting the insufficient number. Then, the calculation unit 110 selects the number of nozzles N that can be maintained from among the nozzles N possessed by the component mounter 3 as maintenance target nozzles based on the priority criteria (suction rate or number of shots). When the adsorption rate is adopted as the priority criterion, nozzles N having a low adsorption rate are preferentially selected as maintenance target nozzles. Alternatively, when the number of shots is adopted as the priority criterion, the nozzles N with the largest number of shots are preferentially selected as maintenance target nozzles.

In step S107, the calculation unit 110 determines the missing nozzles N confirmed for the component mounter 3 and the nozzles N selected as maintenance target nozzles (in other words, the maintenance nozzles to be replaced with the maintenance target nozzles). Nozzle type N) is determined as a delivery target nozzle to be delivered to the component mounter 3, and delivery target nozzle information is created (FIG. 12A). FIG. 12A is a diagram showing a second example of delivery target nozzle information indicating delivery target nozzles for the component mounting machine. In the delivery target nozzle information in FIG. 12A, a status is added compared to that in FIG. 8C. In this status, "Added" indicates nozzles N delivered from the setup device 2 to the component mounter 3 in order to make up for the shortage of nozzles N in the component mounter 3, and "Replaced" indicates nozzles to be maintained. A nozzle N delivered from the setup device 2 to the component mounter 3 for replacement with the nozzle N recovered from the component mounter 3 to the setup device 2 is shown. However, this "status" does not necessarily have to be included in the delivery target nozzle information. In this way, the delivery mode of the nozzle N is determined.

At step S72 in FIG. 9, the recovery mode determination (selective exchange mode) in FIG. 11 is executed. In step S201 of FIG. 11, the calculation unit 110 confirms the nozzle N selected as the maintenance target nozzle in step S106 for each component mounter 3 . Then, in step S202, the calculation unit 110 determines the nozzle N selected as the maintenance target nozzle as a recovery target nozzle to be recovered from the component mounter 3 to the setup device 2, and creates recovery target nozzle information (Fig. 12B). FIG. 12B is a diagram showing an example of recovery target nozzle information indicating recovery target nozzles from the component mounter. The recovery target nozzle information includes the pallet ID of the pallet P used to recover the recovery target nozzles N, and the type Nk and nozzle ID of the nozzles N placed on the pallet P and recovered from the component mounter 3. The component mounter 3 is shown. The pallet P used for recovering the nozzles N is the pallet P that is transported to the component mounter 3 for delivery of the nozzles N to the component mounter 3 having the nozzles N to be recovered. Thus, the recovery mode of the nozzle N is determined.

In step S73 of FIG. 9, a delivery preparation command for causing the setup device 2 to execute delivery preparation for preparing the pallet P on which the nozzle N is placed according to the delivery target nozzle information obtained in step 107 is sent to the computing unit 110. is created by and stored in the storage unit 140 . Further, in step S73, a recovery command for recovering the nozzle N from the component mounter 3 to the setup device 2 is created by the calculation unit 110 according to the recovery target nozzle information obtained in step S202, and stored in the storage unit 140. Saved.

FIG. 13 is a flow chart showing a third example of determination of the delivery mode executed in the flow chart of FIG. 9, and FIG. 14 is a flow chart showing a second example of collection mode determination executed in the flow chart of FIG. The flowcharts of FIGS. 13 and 14 are individually executed for each of the plurality of board production lines L by the server computer 100. FIG.

In step S71 of command creation in FIG. 9, the delivery mode determination (FIG. 13) is executed. In this example, a delivery mode in a complete replacement mode in which nozzles N lacking in the execution of component mounting and nozzles N to be replaced for maintenance of all the nozzles N possessed by the component mounter 3 are delivered to the component mounter 3. Explain the decision.

Also in FIG. 13, steps S101 to S103 are executed for each mounter 3 as in the above example. That is, pallets P are assigned to a plurality of mounters 3 (step S101). Then, based on the result of confirming the owned nozzles and the nozzles to be used in step S102, the missing nozzles N are confirmed.

In the next step S108, the calculation unit 110 selects all the nozzles N owned by the mounter 3 as maintenance target nozzles. Then, in step S109, the calculation unit 110 determines the missing nozzles N confirmed for the mounter 3 and the nozzles N selected as the maintenance nozzles (in other words, the maintenance nozzles to be replaced with the maintenance nozzles). and the same type of nozzle N) as the delivery target nozzles to be delivered to the component mounter 3, and the delivery target nozzle information is created in the same manner as described above.

At step S72 in FIG. 9, the recovery mode determination (full replacement mode) in FIG. 14 is executed. In step S201 of FIG. 14, the calculation unit 110 confirms the nozzle N selected as the maintenance target nozzle in step S108 for each component mounter 3. FIG. Then, in step S202, the calculation unit 110 determines the nozzle N selected as the maintenance target nozzle as the recovery target nozzle to be recovered from the component mounter 3 to the setup device 2, and performs recovery target nozzle information as described above. to create In this way, the recovery mode of the nozzle N is determined.

In step S73 of FIG. 9, a shipping preparation command for causing the setup device 2 to prepare the pallet P on which the nozzle N is placed according to the shipping target nozzle information obtained in step 109 is sent to the computing unit 110. is created by and stored in the storage unit 140 . Further, in step S73, a recovery command for recovering the nozzle N from the component mounter 3 to the setup device 2 is created by the calculation unit 110 according to the recovery target nozzle information obtained in step S202, and stored in the storage unit 140. Saved.

As described above, the delivery mode can be executed in each of the basic mode, selective exchange mode, and all exchange mode. At this time, only one of these modes may be executed, or a mode selected by the operator operating the UI 120 may be executed. The latter can be configured, for example, as follows.

FIG. 15A is a flowchart showing a fourth example of determination of the shipping mode, and FIG. 15B is a flowchart showing an example of collection mode determination executed in response to the determination of the shipping mode of FIG. In the delivery mode determination (mixed mode) of FIG. 15A, it is determined in step S121 whether the mode selected by the operator is the basic mode. If the basic mode has been selected ("YES" in step S121), the basic mode is executed (step S122), and if the basic mode has not been selected ("NO" in step S121) ), the process proceeds to step S123.

At step S123, it is determined whether the mode selected by the operator is the selective replacement mode. If the selective exchange mode is selected ("YES" in step S123), the selective exchange mode is executed (step S124), and if the selective exchange mode is not selected ("NO" in step S123). ), the process proceeds to step S125, and the full replacement mode is executed.

In the recovery mode determination (mixed mode) in FIG. 15B, it is determined in step S221 whether the mode selected by the operator is the basic mode. Then, if the basic mode has been selected ("YES" in step S221), the flow chart of FIG. 15B is terminated, and if the basic mode has not been selected ("NO" in step S221), goes to step S223.

At step S223, it is determined whether the mode selected by the operator is the selective replacement mode. If the selective exchange mode is selected ("YES" in step S223), the selective exchange mode is executed (step S224). If the selective exchange mode is not selected ("YES" in step S223) NO"), the flow advances to step S225 to execute the full replacement mode.

As described above, a delivery preparation command for the setup device 2 and a collection command for the component mounter 3 are created. Next, a flow of transmitting these commands to the setup device 2 or the component mounter 3 and executing an operation according to the commands will be described.

FIG. 16 is a flow chart showing a first example of line setup management for managing setup in each board production line of the component mounting system. The flow chart of FIG. 16 is executed under the control of the computing section 110 of the server computer 100 . In step S301, the computing unit 110 predicts the completion time of the board production being executed for each of the plurality of board production lines L. FIG.

In step S302, the computing unit 110 creates, for each of the plurality of board production lines L, a command (shipment preparation command/recovery command) for board production scheduled to be executed next to the board production currently underway. Creation of this command can be performed in the basic mode, the selective replacement mode, or the full replacement mode described above. Therefore, when creating commands in the basic mode, a delivery preparation command is created, and when creating commands in the selective exchange mode or all exchange mode, a delivery preparation command and a collection command are created. Further, in step S302, the time to send each command is determined based on the expected completion time of board production. For example, the calculation unit 110 calculates the preparation time required for preparation for shipping in the setup device 2 from the content of the preparation for shipping, and transmits a command at a time earlier than the expected completion time of board production by the time obtained by adding the margin time to the preparation time. Set the time.

Then, when the current time reaches the command transmission time (step S303), the calculation unit 110 transmits the command (shipping preparation command/collection command) created in step S302 to the target devices (the setup device 2 and the component mounter 3). (step S304). Steps S303 and S304 are repeated until transmission of all commands created in step S302 is completed ("YES" in step S305).

FIG. 17 is a flow chart showing a first example of command reception processing executed by the setup device. When the controller 200 of the setup device 2 receives the delivery preparation command from the server computer 100 ("YES" in step S401), the nozzle N indicated by the delivery preparation command is placed on the pallet P indicated by the delivery preparation command (step S402). When all the nozzles N indicated by the delivery preparation command are placed on the pallet P and the delivery preparation is completed ("YES" in step S403), the process proceeds to step S404. Incidentally, the operations specifically executed by the setup device 2 to prepare for shipping are as shown in steps S11 to S15 in FIG. 2C.

In step S404, the controller 200 determines whether or not the pallet P on which the nozzles N are placed can be carried out from the setup device 2 to the component mounter 3 of the board production line L to which the setup device 2 belongs in preparation for delivery. It judges based on the operation status received from 3. Specifically, the controller 200 determines whether the component mounter 3 has received the pallet P based on the operation status of the component mounter 3 to which the pallet P is to be transferred (component mounting in progress, component mounting completed, board unloading completed, etc.). Check if you can run If the pallet can be accepted, it is determined that the pallet P can be carried out to the component mounting machine 3 ("YES" in step S404), and the pallet P is carried out from the setup device 2 to the component mounting machine 3. Specifically, as described above, the pallet P on which the nozzles N are placed is transported from the delivery conveyor 27 of the setup device 2 to the board conveyor 31 of the component mounter 3 in preparation for delivery, and then transferred to the component mounter 3. be brought in. Incidentally, the operation specifically executed by the setup device 2 to take out the nozzle N is as shown in steps S16 to S19 in FIG. 2D.

FIG. 18A is a flowchart showing a first example of command reception processing executed by the mounter. When the pallet P is carried into the component mounter 3 ("YES" in step S501), the controller 300 of the component mounter 3 stops the pallet P at a predetermined pallet stop position (step S502). At step S503, the controller 300 determines whether or not a recovery command has been received from the server computer 100. If the collection command has not been received ("NO" in step S503), the controller 300 uses the mounting head 331 to receive the nozzles N placed on the pallet P (receiving operation). On the other hand, if the recovery command has been received (“YES” in step S503), the controller 300 causes the mounting head 331 to select the recovery target nozzles indicated by the recovery command among the nozzles N possessed by the component mounter 3. A moving operation for moving from the nozzle stocker 37 to the pallet P and a receiving operation are executed. Note that the move operation is executed in parallel with the receive operation. Specifically, when the mounting head 331 moves the nozzle N from the pallet P to the nozzle stocker 37 for the receiving operation, the mounting head 331 picks up the collection target nozzle from the nozzle stocker 37 and moves it to the pallet P. In other words, the receiving operation is performed on the outward path from the pallet P to the nozzle stocker 37 , and the moving operation is performed on the return path from the nozzle stocker 37 to the pallet P.

Thus, when the receiving operation in step S504 or the receiving and moving operations in step S505 are completed, the pallet P is carried out from the component mounter 3 (step S506). At this time, for example, when the transport mode of FIG. , the destination of the pallet P from the component mounter 3 is the setup device 2 or another component mounter 3 .

FIG. 18B is a flowchart showing a second example of command reception processing executed by the mounter. Here, differences from the first example in FIG. 18A will be mainly described, and common parts will be denoted by corresponding reference numerals and description thereof will be omitted as appropriate. As a premise of this second example, the server computer 100 transmits in advance the pallet information regarding the pallet P targeted by the delivery preparation command to the mounter 3 at the same time as transmitting the delivery preparation command to the setup device 2 . . This pallet information associates the pallet stop position at which the pallet P, which is the object of the application preparation instruction, is stopped in the mounter 3 and the arrangement (in other words, position) of the nozzle N on the pallet P with the pallet ID. is shown.

When the pallet P is carried into the component mounter 3 ("YES" in step S501), the controller 300 of the component mounter 3 temporarily stops the pallet P (step S507). The palette ID is read based on the captured image of the palette ID. Then, the controller 300 causes the single-axis robot 384 to adjust the position of the stopper 381 according to the pallet stop position indicated by the pallet ID, and then causes the substrate conveyor 31 to start transporting the pallet P. As a result, the pallet P comes into contact with the position-adjusted stopper 381 and stops at the pallet stop position indicated by the pallet ID (step S503). In the receiving operations of steps S504 and S505, the controller 300 receives the nozzles N while recognizing the type of the nozzles N based on the arrangement of the nozzles N on the palette P indicated by the palette ID.

FIG. 19 is a flow chart showing a second example of line setup management for managing setup in each board production line of the component mounting system. The flowchart of FIG. 19 is executed under the control of the computing unit 110 of the server computer 100. FIG. Here, the difference from the first example in FIG. 16 will be mainly described, and the common parts will be denoted by corresponding reference numerals and description thereof will be omitted as appropriate.

In the second example of FIG. 19, after creating a command for each board production line L, the computing unit 110 checks whether an interrupt request from the worker has been input to the UI 120 . This interrupt request requests that a specific nozzle N be delivered from the setup device 2 to the mounter 3 due to an urgent reason such as breakage of the nozzle N, regardless of the delivery preparation command created in step S302. is. If there is an interrupt request while the delivery preparation command created in step S302 has not yet been transmitted ("YES" in step S306), the computing unit 110 instructs the setup device 2 to release the nozzle N indicated by the interrupt request. is transmitted, and the setup device 2 takes out the target nozzle N according to the instruction (step S307).

Then, in step S308, the calculation unit 110 confirms whether the nozzle N that was delivered in response to the interrupt request was the nozzle N scheduled to be delivered in response to the delivery preparation command created in step S302. Specifically, the confirmation in step S308 can be performed based on whether the nozzle ID of the former nozzle N and the nozzle ID of the latter nozzle N match. Then, if the nozzle N that has left the warehouse in response to the interrupt request is the nozzle N that is scheduled to leave the warehouse in response to the shipping preparation command (“YES” in step S308), the computing unit 110 issues the shipping preparation command. It is determined that it is necessary to recreate it, and the process returns to step S302. If not ("NO" in step S308), the process proceeds to step S303.

FIG. 20 is a flow chart showing a second example of command reception processing executed by the setup device. Here, the difference from the first example in FIG. 17 will be mainly described, and the common parts will be denoted by corresponding reference numerals and description thereof will be omitted as appropriate. In the second example of FIG. 20, when the controller 200 receives the delivery preparation command ("YES" in step S401), the controller 200 selects the component mounter 3 as the delivery destination of the nozzle N that is the target of the delivery preparation according to the delivery preparation command. It is checked whether there is a recovery target nozzle to be recovered from (step S406). Specifically, it is possible to confirm whether or not there is a nozzle to be collected based on whether or not there is a nozzle for maintenance among the nozzles N to be prepared for delivery.

If there are no recovery target nozzles ("NO" in step S406), the process proceeds to step S402. On the other hand, if there is a nozzle to be collected ("YES" in step S406), the setup device 2 collects the empty pallet P for collection before starting preparation for leaving the warehouse (steps S402 and S403). It is carried out to the component mounter 3 where the target nozzle exists (step S407). Then, the component mounting machine 3 to which this pallet P for recovery has been carried in, prior to taking out the nozzles N from the setup device 2, mounts the nozzles to be recovered on the pallet P, and then transfers the pallet P to the setup device. 2.

By the way, as described above, when the calculation unit 110 transmits a recovery command to the component mounter 3 , the recovery target nozzle is recovered from the component mounter 3 to the setup device 2 . Therefore, the setup device 2 may be configured to execute the flowchart shown in FIG. Here, FIG. 21 is a flow chart showing an example of maintenance preparation executed by the setup device. In step S<b>601 , the controller 200 of the setup device 2 confirms whether or not the pallet P on which the collection target nozzles are placed has been collected from the component mounter 3 to the setup device 2 . After confirming the collection ("YES" in step S601), the controller 200 displays a screen on the display 297 for instructing the operator to perform maintenance (step S602).

As a result, the operator can input maintenance execution instructions to the UI 120. Further, when an execution instruction is input to the UI 120, the transfer head 251 of the setup device 2 moves the maintenance target nozzle from the pallet P collected from the component mounter 3 to the cleaning unit 292, and performs maintenance on the nozzle. Execute.

FIG. 22 is a flowchart showing a fifth example of determining the delivery mode. Here, the description will focus on the difference from the determination of the delivery mode described above, and the common parts will be given corresponding reference numerals and description will be omitted as appropriate. In FIG. 22 as well, steps S101 to S103 are executed for each mounter 3 as in the above example. That is, pallets P are assigned to a plurality of mounters 3 (step S101). Then, based on the result of confirming the owned nozzles and the nozzles to be used in step S102, the missing nozzles N are confirmed.

In the next step S111, the computing unit 110 selects two component mounters that can divert the same nozzle N from among the plurality of component mounters 3 belonging to the same substrate production line L as the setup device 2 that prepares for delivery. Check if 3 exists. Specifically, "out of the plurality of component mounters 3, a nozzle N (divertible nozzle) that is owned by one component mounter 3 and is not scheduled to be used (nozzle N that is scheduled to be used by another component mounter 3) It is confirmed whether or not there is a nozzle N that satisfies the diversion condition such as "the nozzle N but not the owned nozzle N".

If there is a nozzle N that satisfies the diversion condition ("YES" in step S111), the nozzle N to be used by another component mounter 3 is not taken out from the setup device 2, but It is determined to move from the component mounter 3 to another component mounter 3 (step S112). A pallet P is used to move the nozzle N from one component mounter 3 to another component mounter 3 . As this pallet P, the pallet P used for delivery to one component mounter 3 can be used. Then, in step S112, in determining the delivery target nozzles for the other mounters 3, the nozzles N satisfying the diversion condition are excluded from the shortage of nozzles N confirmed for the other mounters 3. is determined as the nozzle to be delivered.

By the way, in the determination of the delivery mode, the detailed conditions of the delivery mode such as the position of the nozzle N to be placed on the pallet P and the stop position of the pallet P (pallet stop position) in the component mounter 3 to be delivered are set as follows. can be managed as FIG. 23 is a flow chart showing an example of detailed condition management of the delivery mode. The flowchart of FIG. 23 is executed by the computing unit 110 of the server computer 100 for the nozzle N determined as the nozzle to be delivered in the delivery mode determination, and the details of the optimal delivery mode are changed while the detailed conditions of the delivery mode are changed. to decide.

At step S701, the calculation unit 110 confirms the delivery target nozzle. In step S702, the stop position variable Vs, which is a variable indicating the position at which the pallet P used for the delivery of the delivery target nozzle stops in the delivery destination component mounting machine 3, is reset, and in step S703, the stop position variable Vs is incremented by one. do. Here, different stop position variables Vs indicate different pallet P stop positions. Furthermore, the nozzle arrangement variable Va, which is a variable indicating the positional variation of the nozzles to be delivered to the pallet P, is reset, and in step S705, the nozzle arrangement variable Va is incremented by one. Here, different nozzle placement variables Va indicate different placements of nozzles N with respect to pallet P, in other words, different combinations of nozzles N placement modes.

In step S706, when the pallet P on which the nozzles N are mounted in the arrangement indicated by the nozzle arrangement variable Va is stopped at the position indicated by the stop position variable Vs in the component mounter 3 that is the delivery destination, the calculation unit 110 The time (operation time) required for the component mounting machine 3 to receive the nozzle N from the pallet P is predicted. The calculations of steps S705 and S706 are repeated until the nozzle arrangement variable Va reaches a predetermined value Vax. Furthermore, the calculations of steps S703 to S707 are repeated until the stop position variable Vs reaches a predetermined value Vsx.

In this way, the operation time of the receiving operation is predicted for each of a plurality of combinations in which the arrangement of the nozzles N with respect to the pallet P or the stopping position of the pallet P is different. Then, in step S709, the calculation unit 110 identifies the optimum combination of the arrangement of the nozzles N and the stop position of the pallet P that minimizes the operation time from among these combinations, and determines the arrangement indicated by this optimum combination. It is decided to place the nozzle N and to stop the pallet P at the stop position. The contents of this decision are transmitted from the server computer 100 to the setup device 2 and the component mounter 3, and the setup device 2 arranges the nozzles N on the pallet P in the arrangement indicated by the optimum combination to prepare for delivery. stops the pallet P at the position indicated by the optimum combination.

In the setup device 2 of the embodiment described above, the pallet P (conveyance pallet) on which the nozzles N (used members) taken out from the pallet storage 22 (member storage) are placed is transferred to the board conveyor of the component mounter 3. 31 is provided with a pallet transport unit 26.

conveyors

24s and 24c are matched by the elevator 233. With such a configuration, the pallet P can be accurately received from the pallet transport section 26 to the transport conveyor 24c.

The pallet transport section 26 is arranged in series with the transfer conveyor 28 arranged adjacent to the pallet take-out section 23 and the substrate conveyor 31 of the component mounting machine 3 and arranged between the transfer conveyor 28 and the substrate conveyor 31. and an outgoing conveyor 27. This delivery conveyor 27 conveys the pallet P from the delivery conveyor 28 to the substrate conveyor 31 . On the other hand, the transfer conveyor 28 has a rotational position R1 (first position) at which the pallet P is transferred to and from the delivery conveyor 27, and a rotational position R2 (second position) at which the pallet P is transferred to and from the pallet takeout section 23. is displaced between In such a configuration, the delivery conveyor 28 conveys the pallet P on which the nozzle N is placed from the pallet take-out section 23 to the delivery conveyor 27 .

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made to the above without departing from the spirit of the present invention. For example, the configuration of the setup device 2 can be changed as appropriate. Specifically, the setup device may be modified as shown in FIG. 24, for example.

FIG. 24 is a plan view schematically showing a modification of the setup device. The difference between the setup device 2 of FIG. 24 and that of FIG. Therefore, this difference will be mainly described, and the common parts will be denoted by corresponding reference numerals, and the description thereof will be omitted as appropriate. In the example of FIG. 24A, the orientation of the main housing 211 and the components housed therein is different by 90 degrees compared to the example of FIG. 2A. Further, the displacement direction of the delivery conveyor 28 of the pallet transport section 26 is not the rotation direction but the Y direction.

Also, the arrangement of the setup device 2 in the substrate production line L may be changed as appropriate. That is, the setup device 2 does not necessarily have to be positioned at the end of the substrate production line L. That is, since the setup device 2 has the delivery conveyors 27 on both sides of the delivery conveyor 28 in the Y direction, the pallets P can be carried out to both sides in the Y direction. Therefore, the setup device 2 can be arranged between the two component mounters 3 arranged in the Y direction. Conversely, when the setup device 2 is arranged at the end of the board production line L, one of the two delivery conveyors 27 of the setup device 2 is not necessarily required.

As shown in FIG. 25, the mounter 3 has a horizontally supported backup plate 39 on which backup pins BP are arranged. The substrate B on the substrate conveyor 31 is supported from below by backup pins BP.

On the other hand, in the backup pin shipping preparation of FIG. 26, the calculation unit 110 confirms whether or not the backup pins BP are insufficient for each mounter 3 (step S801). Then, if there is a component mounter 3 with insufficient backup pins BP ("YES" in step S802), the calculation unit 110 determines that the component mounter 3 is to be a delivery target for the backup pins BP, A palette P is assigned to this (step S803). Further, the calculation unit 110 determines the number of backup pins BP to be delivered to the component mounter 3 (step S804), places this number of pallets P on the pallet P, and directs them to the target component mounter 3. A pin delivery command is issued to the setup device 2 so that the pin is delivered to the warehouse (step S805).
