The distance between the two guide rollers 55R facing each other in the X-axis direction (the distance in the X-axis direction) is slightly larger than the width in the X-axis direction of the pedestal back portion 41B of the nozzle replacement table 31. In addition, the distance between the upper surface of the base plate 51 and the lower surface of each pressing member 55P (the distance in the Z-axis direction) is slightly larger than the dimension in the thickness direction of the pedestal back portion 41B of the nozzle replacement table 31. .

  12, the shutter operation cylinder 56 is provided at a position closer to the center of the base 11 than the elevating cylinder 54 with the shutter operation rod 56R, which is a piston rod, directed in the X-axis direction. The shutter operating section 57 extends in the Z-axis direction, and the lower end thereof is connected to the distal end of the shutter operating rod 56R. When the shutter operation cylinder 56 operates the shutter operation rod 56R, the shutter operation section 57 moves in the X-axis direction while maintaining the posture extended in the Z-axis direction.

  In the case where the feeder cart 14 is connected to the base 11 and held by the exchange stand holder 32 (that is, the nozzle exchange base 31 is installed on the base 11), first, the carrier holding member 14A of the feeder cart 14 is used. The nozzle replacement table 31 is mounted on the mounting table 36 attached to the nozzle. When mounting the nozzle replacement table 31 on the mounting table 36, the pedestal 41 of the nozzle replacement table 31 is mounted on the upper surface of the mounting table 36 (FIG. 9 → FIG. 14). At this time, the positioning protrusion 41K on the lower surface of the pedestal 41 is fitted into the fitting hole 36K of the mounting table 36 from above, and the mounting table 36 is positioned between the two guide protrusions 41T. As a result, the nozzle replacement table 31 is positioned at a specified position with respect to the mounting table 36 (FIG. 14).

  After placing the nozzle replacement table 31 on the mounting table 36, the operator OP moves the feeder truck 14 on the floor surface and transports it to the base 11, and connects the truck-side connector 14C of the feeder truck 14 to the base-side connector 11C. To fit. When the mating is detected by the cart detection sensor 11M, the cart lock unit 11R controlled by the control device 20 locks the feeder cart 14 to the base 11, and connects the feeder cart 14 to the base 11. When the feeder trolley 14 is connected to the base 11, the nozzle replacement table 31 mounted on the mounting table 36 is replaced in the area between the parts feeder 15 attached to the feeder trolley 14 and the replacement table holder 32. It is delivered to the table holder 32.

  When the feeder trolley 14 is pushed into the base 11, the pedestal deep portion 41 </ b> B of the nozzle exchange table 31 mounted on the mounting table 36 is located in the space between the lifting plate 55 of the exchange table holder 32 and the pressing member 55 </ b> P. It enters (FIG. 15 → FIG. 16 → FIG. 17). As a result, the exchange table holder 32 receives the nozzle exchange table 31 from the mounting table 36. When the pedestal back part 41B of the nozzle replacement pedestal 31 enters between the lifting plate 55 of the replacement pedestal holding part 32 and the pressing member, the two guided surfaces 41G at both ends of the pedestal back part 41B of the nozzle replacement pedestal 31 are replaced. It is guided from the side (X-axis direction) by four (two right and left) guide rollers 55 </ b> R provided in the table holder 32.

  The pedestal inner part 41B of the nozzle exchange table 31 that has entered between the lifting plate 55 and the pressing member 55P as described above rises a little while pressing the pressing member 55P upward. Therefore, the nozzle exchange table 31 moves obliquely upward toward the center of the base 11 with respect to the exchange table holder 32 while raising the elevating plate 55 (FIG. 16 → FIG. 17).

  When the nozzle exchanging table 31 moves obliquely upward toward the center of the base 11 with respect to the exchanging table holding unit 32, the left and right upper and lower rollers 43 become two roller guides provided on the exchanging table holding unit 32. It enters the guide groove 63 of 53 (FIG. 16 → FIG. 17, see arrows M1 and M2 shown in FIG. 16). In detail, the upper roller 43 of the upper and lower rollers 43 enters the guide groove 63 through the groove 61M provided in the front wall 61 (arrow M1), and the lower roller 43 is the lower front wall. It enters the guide groove 63 from below 61 (arrow M2).

  The right and left upper and lower rollers 43 complete the entry of the left and right roller guides 53 into the guide grooves 63 when the feeder cart 14 is connected to the base 11. When the feeder cart 14 is locked to the base 11 by the cart lock unit 11R and is connected to the base 11, the lifting cylinder 54 raises the lifting plate 55. As a result, the nozzle exchange table 31 is lifted by the elevating cylinder 54 via the elevating plate 55 (FIG. 17 → FIG. 18), and the pedestal 41 of the nozzle exchange table 31 is separated from the elevating plate 55 of the exchange table holder 32 (accordingly. , Mechanically separated from the feeder cart 14) and moves upward. Then, when the nozzle replacement table 31 reaches a position at a predetermined height corresponding to the above-described holding position, the lifting cylinder 54 stops lifting the lifting plate 55.

  When the nozzle exchange table 31 is lifted by the elevating cylinder 54, the four rollers 43 of the nozzle exchange table 31 (the left and right upper and lower rollers 43) are guided by the guide grooves 63 of the left and right roller guides 53, and are in the guide grooves 63. Moves straight (up) vertically upward. Then, when the nozzle replacement table 31 is located at the holding position, the left and right upper and lower rollers 43 are sandwiched by the front wall 61 and the rear wall 62, respectively. Therefore, the nozzle exchange table 31 is firmly held at a predetermined holding position by the exchange table holding unit 32 (FIGS. 18 and 19).

  As described above, the component mounting apparatus 1 according to the present embodiment is provided on the base 11 and the nozzle replacement table 31 that holds the replacement nozzle 21 that is attached to and detached from the mounting head 17. A holding table 32 for holding the nozzle changing table 31 at a predetermined holding position, a mounting table 36 provided on the feeder cart 14 and for mounting the nozzle changing table 31 before being held by the changing table holding section 32; It is provided with. Then, when the feeder cart 14 is connected to the base 11, the exchange table holder 32 receives the nozzle exchange table 31 from the mounting table 36, raises the same, and holds the nozzle exchange table 31 in a state where the nozzle exchange table 31 is separated from the mounting table 36. It is designed to be held in position.

  The exchange table holding section 32 serves as an exchange table moving means for elevating and lowering the nozzle exchange table 31 received from the mounting table 36 such that the elevation cylinder 54 and the nozzle exchange table 31 which is moved up and down by the elevation cylinder 54 rise toward the holding position. The nozzle exchange table 31 is guided by the left and right roller guides 53 when the nozzle exchange table 31 is moved upward by the elevating cylinder 54. By doing so, it rises straight up vertically and is held at the holding position.

  In addition, as described above, the nozzle exchange table 31 is moved obliquely upward toward the center of the base 11 with respect to the exchange table holding unit 32 (see FIG. 16 → FIG. 17). The operated piece 48 is located on the side of the shutter operating section 57 provided in the exchange table holding section 32 (FIGS. 16 → 17 and 20 (a) → FIG. 20 (b)). After that, the nozzle exchange table 31 is moved upward by the lifting cylinder 54. At this time, since the nozzle exchange table 31 moves straight upward, the operated piece 48 is located on the side of the shutter operation section 57. The state is maintained (FIG. 17 → FIG. 18).

  As described above, when the nozzle exchanging table 31 is held at the predetermined holding position by the exchanging table holding unit 32, the operated piece 48 is located on the side of the shutter operating unit 57. By moving the operation unit 57 in the X-axis direction, the shutter 46 can be switched from the closed position to the open position (FIG. 21A → FIG. 21B). When the shutter operation section 57 is returned to the original position by the shutter operation cylinder 56 after switching the shutter 46 to the open position, the shutter 46 returns to the closed position by the urging force of the urging member 49 (FIG. 21B). ) → FIG. 21 (a)).

  As described above, in the present embodiment, the shutter operation unit 57 as the movable unit operation unit that operates the shutter 46 that is the movable unit of the nozzle exchange table 31 and the shutter operation cylinder 56 as the actuator that drives the shutter operation unit 57 are formed. It is provided in the exchange stand holder 32. Then, in a state where the nozzle exchange table 31 is held at the holding position by the exchange table holding unit 32, the shutter operation unit 57 is located at a position where the shutter 46 of the nozzle exchange table 31 can be operated.

  In FIG. 9, a mounting state detection sensor 71 is provided on the mounting table 36. The placement state detection sensor 71 detects a state where the nozzle replacement table 31 is placed on the placement table 36, and outputs a detection signal to the control device 20. The control device 20 detects a state in which the nozzle replacement table 31 is mounted on the mounting table 36 based on an output of the mounting state detection sensor 71.

  In FIG. 12, a holding state detection sensor 72 is provided in the exchange table holding unit 32. The holding state detection sensor 72 detects a state in which the nozzle replacement table 31 is held at the holding position based on the amount of downward projection of the piston rod (elevation rod 54R) of the elevating cylinder 54 and the magnitude of the load. The detection signal is output to the control device 20. The control device 20 detects a state in which the nozzle replacement table 31 is held at the holding position based on the output of the holding state detection sensor 72.

  As described above, when the feeder trolley 14 is pushed into the base 11, the component disposal box 33 attached to the feeder trolley 14 enters the equipment installation area of the base 11, and moves below the discharge port 35 </ b> Q of the shooter 35. (FIG. 22 (a) → FIG. 22 (b)). Therefore, the worker OP can install the parts disposal box 33 within the movable range of the mounting head 17 by connecting the feeder truck 14 to the base 11 without opening the door portion 12C of the base cover 12. it can.

  The replacement work of the nozzle 21 is performed in a state where the nozzle replacement table 31 is held at the holding position by the replacement table holding unit 32. The replacement work of the nozzle 21 is performed by holding the nozzle 21 attached to the nozzle shaft 17S on the nozzle replacement base 31 and removing it from the nozzle shaft 17S, and then replacing the replacement nozzle 21 held on the nozzle replacement base 31 with the nozzle. This is performed by attaching to the shaft 17S. At this time, when there are a plurality of nozzles 21 to be exchanged, the exchange operation for the plurality of nozzles 21 is collectively executed.

  When removing the nozzle 21 from the nozzle shaft 17S in the nozzle replacement work, first, the shutter operation cylinder 56 is operated to move the shutter 46 from the closed position to the open position (FIG. 21A → FIG. 21B). )). Then, the mounting head 17 moves, and the vertical center axis of the nozzle 21 is aligned with the vertical center axis of the nozzle insertion hole 45H of the nozzle replacement table 31. When the vertical center axis of the nozzle 21 coincides with the vertical center axis of the nozzle insertion hole 45H, the mounting head 17 lowers the nozzle shaft 17S, and moves the nozzle 21 attached to the nozzle shaft 17S to the vacant nozzle insertion hole 45H. Insert.

  When the nozzle 21 is inserted into the nozzle insertion hole 45H, the shutter operation cylinder 56 operates to move the shutter 46 from the open position to the closed position (FIG. 21 (b) → FIG. 21 (a)). When the mounting head 17 pulls the nozzle shaft 17S upward with the shutter 46 at the closed position, the flange portion 24 of the nozzle 21 interferes with the shutter 46 and is prevented from moving upward. The nozzle 21 is removed from the nozzle 17S and remains on the nozzle changing table 31. As a result, the nozzle 21 is removed from the nozzle shaft 17S.

  When the replacement nozzle 21 is attached to the nozzle shaft 17S from which the nozzle 21 has been removed in this way, first, the mounting head 17 moves and the replacement nozzle 21 held on the nozzle replacement table 31 is moved. The nozzle shaft 17S to which the nozzle 21 is attached is located above. Then, the vertical center axis of the nozzle shaft 17S is made to coincide with the vertical center axis of the nozzle 21, and the nozzle shaft 17S is lowered. As a result, the base 22 of the replacement nozzle 21 is connected (fitted) to the lower end of the nozzle shaft 17S.

  When the base 22 of the nozzle 21 is connected to the lower end of the nozzle shaft 17S, the shutter operation cylinder 56 operates to move the shutter 46 from the closed position to the open position (FIG. 21 (a) → FIG. 21 (b)). When the shutter 46 is located at the open position, the mounting head 17 pulls the nozzle shaft 17S upward. As a result, the nozzle 21 is pulled up in a state where the nozzle 21 is connected to the lower end of the nozzle shaft 17S, and the nozzle 21 for replacement is attached to the nozzle shaft 17S. Thus, the replacement work of the nozzle 21 is completed.

  When the nozzle exchange table 31 held at the holding position by the exchange table holding unit 32 is detached by the operation of separating the feeder cart 14 from the base 11, before the feeder cart 14 is separated from the base 11, the lifting cylinder 54 lowers the lifting plate 55. As a result, the nozzle exchange table 31 lifted by the lifting plate 55 moves on a path reverse to that when it is held at the holding position, and is mounted on the mounting table 36 provided on the feeder cart 14. . At this time, the four rollers 43 of the nozzle exchange table 31 move straight down vertically through the guide grooves 63 of the two roller guides 53 included in the exchange table holder 32 (FIG. 18 → FIG. 17).

  After the nozzle exchange table 31 is mounted on the mounting table 36 as described above, when the feeder carriage 14 is separated from the base 11, the nozzle exchange table 31 remains mounted on the mounting table 36. It moves obliquely downward toward the direction away from the center of the table 11 and separates from the elevating plate 55 (FIG. 17 → FIG. 16). After that, it moves together with the feeder truck 14 while being placed on the placing table 36, and separates from the base 11 (FIG. 16 → FIG. 15). As described above, the exchange table holding unit 32 lowers the nozzle exchange table 31 from the holding position and mounts the nozzle exchange table 31 on the mounting table 36.

  As described above, when the feeder trolley 14 is separated from the base 11, the component disposal box 33 attached to the feeder trolley 14 is retracted outside the equipment installation area of the base 11 (FIG. 22 (b) → FIG. 22 (a)). For this reason, in this embodiment, by separating the feeder cart 14 from the base 11, the component disposal box 33 can be separated from the movable range of the mounting head 17.

  As the production of boards by the component mounting apparatus 1 progresses, it is necessary to supply the nozzles 21 of a type not held by the nozzle replacement table 31 to the component mounting apparatus. In this case, the operator OP performs the replacement work of the nozzle replacement table 31. In addition, as the production of the board proceeds, it is necessary to replace the component disposal box 33 in order to collect the waste components stored in the component disposal box 33 up to that time.

  Such a replacement operation of the nozzle replacement table 31 and the component disposal box 33 is performed in a state where the component mounting operation on the side where the nozzle replacement table 31 and the component disposal box 33 to be replaced is installed is stopped. With the door 12C opened, the operator OP can insert the hand into the work space 11S to perform the operation. However, in this case, since the safety device operates by opening the door portion 12C, while performing the replacement work of the nozzle replacement table 31 or the replacement work of the parts disposal box 33, the parts on the opposite side to the work side are performed. The mounting operation is also forcibly stopped.

  In the present embodiment, as described above, by connecting the feeder cart 14 to the base 11, the nozzle replacement table 31 and the parts disposal box 33 are moved within the installation area of the base 11 (that is, the movable range of the mounting head 17). And the feeder cart 14 is separated from the base 11, so that the nozzle replacement table 31 and the parts disposal box 33 can be separated from the equipment installation area of the base 11. The nozzle replacement table 31 can be replaced with the component disposal box 33 without opening the 12C. In this case, the operator OP does not need to open the door portion 12C of the base cover 12, so that the safety device does not operate, and the nozzle replacement table 31 and the parts disposal box 33 are replaced on one of the front side and the rear side. Is performed, the component mounting operation is continued on the other side, so that the operation of the component mounting apparatus 1 as a whole is maintained.

  Therefore, in the component mounting apparatus 1 according to the present embodiment, the replacement of the nozzle replacement table 31 and the replacement of the component disposal box 33 (that is, the recovery of the waste component) can be easily performed without opening the door portion 12C of the base cover 12. Can be done. Further, since the door portion 12C cannot be opened, the safety device does not work and the component mounting operation is not forcibly stopped, and the replacement work of the nozzle replacement table 31 and the replacement work of the component disposal box 33 can be performed efficiently. . Next, the flow of operation of each part of the component mounting apparatus 1 in the replacement work of the nozzle replacement table 31 by the feeder cart 14 will be described.

  FIG. 23 shows an operation flow of the component mounting apparatus 1 in a case where the feeder truck 14 connected to the base 11 is separated from the base 11 in the replacement work of the nozzle replacement table 31. When separating the feeder truck 14 connected to the base 11 from the base 11, the operator OP first performs an input operation for requesting permission (separation permission) to separate the feeder truck 14 from the touch panel TP. (Step ST1 in the flowchart of FIG. 23). The operation for requesting the separation permission is performed from the touch panel TP on the side where the worker OP is going to separate the feeder cart 14. More specifically, when the feeder truck 14 on the front side of the base 11 is to be separated from the base 11, an operation of requesting permission of separation is performed from the touch panel TP on the front side, and the feeder truck on the rear side of the base 11 is operated. When the user wants to separate the base 14 from the base 11, a request for separation permission is performed from the rear touch panel TP.

  When the control device 20 detects that the operation for requesting the separation has been performed from the touch panel TP, the control unit 20 separates the feeder carriage 14 from the base 11 when the nozzle replacement platform held by the replacement platform holding unit 32. 31 is also notified to the operator OP to confirm whether to remove it together (step ST2). This notification is performed by displaying a message inquiring on the screen of the touch panel TP as to whether or not the nozzle exchange table 31 is to be removed. Then, when the operator OP inputs a response to the notification on the touch panel TP (step ST3), the control device 20 checks the contents of the response input by the operator OP in step ST3 (step ST4). Then, when the input answer removes the nozzle exchange table 31, the control device 20 operates the elevating cylinder 54 of the exchange table holding unit 32 to lower the nozzle exchange table 31 and place it on the mounting table 36. Thereby, the nozzle exchange table 31 is detached from the exchange table holder 32 (step ST5).

  After removing the nozzle exchange table 31 from the exchange table holding unit 32, the control device 20 determines whether or not the nozzle exchange table 31 has been normally removed based on the output from the placement state detection sensor 71 ( Step ST6). Specifically, when it is detected that the nozzle exchange table 31 is mounted on the mounting table 36 within a predetermined time after the operation of the elevating cylinder 54 is started, the nozzle exchange table 31 is normally removed. Judge that it was done. On the other hand, if it is not detected that the nozzle replacement table 31 has been mounted on the mounting table 36 even after the predetermined time has elapsed, it is determined that the nozzle replacement table 31 has not been properly removed. .

  If the control device 20 determines that the removal of the nozzle replacement table 31 has been performed normally, the control apparatus 20 causes the bogie lock unit 11R to perform an operation of unlocking the feeder bogie 14 (step ST7). On the other hand, if it is determined that the removal of the nozzle replacement table 31 has not been performed normally, the control device 20 operates through the touch panel TP without causing the carriage lock unit 11R to perform the operation of unlocking the feeder carriage 14. The user OP is notified of an error (step ST8). If the controller 20 confirms in step ST4 that the answer input by the operator OP does not remove the nozzle exchange table 31, the control apparatus 20 removes the nozzle exchange table 31 from the exchange table holding unit 32. Instead, the truck lock unit 11R releases the lock of the feeder truck 14 (step ST7).

  When the unlocking of the feeder trolley 14 by the trolley lock unit 11R is completed, the control device 20 notifies the worker OP via the touch panel TP that the unlocking of the feeder trolley 14 is completed (step ST9). Upon receiving the notification that the lock of the feeder cart 14 has been released via the touch panel TP, the operator OP operates the feeder cart 14 to separate it from the base 11 (step ST10). Thus, the operation of separating the feeder cart 14 from the base 11 is completed.

  As described above, in the component mounting apparatus 1 according to the present embodiment, when an input requesting permission to separate the feeder truck 14 from the base 11 is input from the touch panel TP as an input unit, the control device 20 controls the exchange platform. An inquiry is made to the operator OP as to whether or not the nozzle exchange table 31 held by the holding section 32 is to be removed from the exchange table holding section 32, and if the answer from the operator OP is to remove the nozzle exchange table 31. For example, the nozzle exchange table 31 is removed from the exchange table holding section 32 and is placed on the mounting table 36, and then the carriage lock section 11R unlocks the feeder cart 14, and the answer is that the nozzle exchange table 31 is held by the exchange table. If the contents are not to be removed from the unit 32, the lock of the feeder truck 14 can be locked to the truck lock unit 11R without causing the replacement table holding unit 32 to remove the nozzle replacement table 31. And it is adapted to release the.

  In the above example, when the feeder cart 14 is separated from the base 11, the nozzle exchange table 31 held by the exchange table holding section 32 can be removed together, so that the door section 12C of the base cover 12 is not opened. Also, the replacement work of the nozzle replacement table 31 can be easily performed. As described above, when the component mounting operation of the component mounting apparatus 1 is not performed at all, as described above, the operator OP opens the door portion 12C, inserts the hand into the work space 11S, and manually replaces the door. It is also possible to perform the replacement work of the nozzle replacement table 31 with respect to the table holding unit 32. In this case, when manually removing the nozzle exchange table 31 held by the exchange table holding unit 32, the nozzle exchange table 31 located at the holding position may be pulled upward as it is, and when attaching the nozzle exchange table 31, What is necessary is just to follow the procedure reverse to removal.

  FIG. 24 shows an operation flow of the component mounting apparatus 1 in a case where the nozzle replacement table 31 is installed on the base 11 by connecting the feeder truck 14 to the base 11 in the replacement work of the nozzle replacement table 31. ing. When installing the nozzle replacement table 31 on the base 11 by connecting the feeder cart 14 to the base 11, the operator OP first places the nozzle replacement table 31 on the mounting table 36 (FIG. Step ST11 of the flowchart of FIG. 24). Then, an input operation for requesting permission (connection permission) to connect the feeder cart 14 to the base 11 is performed from the touch panel TP (step ST12). This connection permission request operation is performed from the touch panel TP on the side where the operator OP tries to connect the feeder truck 14. Specifically, when the feeder truck 14 is to be connected to the front side of the base 11, a request for connection permission is performed from the front touch panel TP, and the feeder truck 14 is connected to the rear side of the base 11. In such a case, a connection permission request operation is performed from the rear touch panel TP.

  When the control device 20 detects that a connection permission request operation has been performed from the front or rear touch panel TP, the exchange platform on the side where the feeder cart 14 is to be connected to the worker OP through the touch panel TP. A request is made to confirm whether the holding unit 32 is empty (step ST13). This request is made by displaying a message that calls attention to the operator OP on the screen of the touch panel TP. As a result, the operator OP performs an erroneous operation of connecting the feeder cart 14 with the nozzle exchange table 31 in a state where the nozzle exchange table 31 that has not been removed is mounted on the exchange table holding unit 32. There is no. Then, after the operator OP confirms the state in which the nozzle exchange table 31 is not mounted on the exchange table holding unit 32 by visual observation or the like, and gives a reply to that effect from the touch panel TP (step ST14), the control device 20 Then, the operator OP is urged to connect the feeder truck 14 to the base 11 through the touch panel TP (step ST15).

  When prompted to connect the feeder trolley 14 to the base 11, the operator OP pushes the feeder trolley 14 into the base 11 (step ST16). After prompting the worker OP to connect the feeder trolley 14 to the base 11 in step ST15, the control device 20 determines the position where the feeder trolley 14 can be connected to the base 11 based on the output of the trolley detection sensor 11M. Is reached (step ST17). When detecting that the feeder truck 14 has reached a position where the feeder truck 14 can be connected, the control device 20 locks the feeder truck 14 with the truck lock unit 11R and connects the feeder truck 14 to the base 11 (step ST18). The elevating cylinder 54 of the exchange table holder 32 is operated to hold the nozzle exchange table 31 by the exchange table holder 32 (step ST19). Thus, the installation of the nozzle replacement table 31 on the base 11 is completed.

  In the operation shown in the flowchart of FIG. 23, the worker OP determines whether to remove the nozzle replacement table 31 together with the feeder cart 14, but the determination may be made by the component mounting apparatus 1. FIG. 25 is a flowchart showing the modification.

  First, the operator OP performs an input operation requesting permission (separation permission) of separating the feeder cart 14 from the touch panel TP (step ST21). The operation for requesting the separation permission is performed from the touch panel TP on the side where the worker OP is going to separate the feeder cart 14. When the control device 20 detects that the operation of requesting the separation is performed from the touch panel TP, the control device 20 refers to the setup change information stored in the storage unit of the control device 20 or a server device that can communicate with the control device 20. (Step ST22).

  This setup change information is created in advance based on the production plan. Then, if it is confirmed from the setup change information that the nozzle exchange table 31 is to be removed together with the feeder cart 14 for which separation permission has been requested (step ST23), the control device 20 operates the elevating cylinder 54 of the exchange table holder 32. Then, the nozzle replacement table 31 is lowered and mounted on the mounting table 36, thereby removing the nozzle replacement table 31 from the replacement table holder 32 (step ST24). Then, when it is confirmed that the removal of the nozzle replacement table 31 has been performed normally (step ST25), the carriage lock unit 11R releases the lock (step ST26). When the control device 20 confirms that the nozzle replacement table 31 is not removed (step ST23), the control unit 20 skips steps ST24 and ST25 and causes the bogie lock unit 11R to release the lock (step ST26). If it is determined that the nozzle replacement table 31 has not been properly removed, the control device 20 controls the worker OP through the touch panel TP without causing the carriage lock unit 11R to perform the operation of unlocking the feeder carriage 14. (Step ST27).

  When the unlocking of the feeder trolley 14 by the trolley lock unit 11R is completed, the control device 20 notifies the worker OP via the touch panel TP that the unlocking of the feeder trolley 14 is completed (step ST28). Upon receiving the notification that the lock of the feeder cart 14 has been released through the touch panel TP, the operator OP operates the feeder cart 14 to separate it from the base 11 (step ST29). As described above, in the modified example, the component mounting apparatus 1 determines whether to remove the nozzle replacement table 31 based on the information (setup change information) based on the production plan. it can.

In the present embodiment, the separation work standby position is below the feeder cart 14. Then, when the automatic transport vehicle 81 arrives at the separation work standby position (step ST31 in FIG. 27), the first notification unit 821 instructs the control device 20 of the component mounting device 1 to send the automatic transport vehicle 81 the component mounting device 1 Is notified to the mounting system (step ST32). This arrival notification is sent via the information management unit 205 to the control device 20 of the component mounting apparatus 1 on which the feeder cart 14 to be removed is mounted.

  Upon receiving the arrival notification, the determination unit 204 determines whether to remove the nozzle replacement table 31 with reference to the setup change information (step ST33). When the determination unit 204 determines that the nozzle replacement table 31 is to be removed, the second processing unit 203 causes the replacement table holding unit 32 to remove the nozzle replacement table 31 (step ST34). Then, based on the output from the placement state detection sensor 71, it is determined whether or not the removal of the nozzle replacement table 31 by the replacement table holding unit 32 has been performed normally (step ST35). When the determination unit 204 determines that the removal of the nozzle replacement table 31 has been performed normally, the second processing unit 203 starts the separation operation, and causes the carriage lock unit 11R to unlock the feeder carriage 14 (step ST36). .

  On the other hand, if the second processing unit 203 determines in step ST35 that the removal of the nozzle replacement table 31 has not been performed normally, the second processing unit 203 does not allow the bogie lock unit 11R to unlock the feeder bogie 14 without touching the touch panel. An error notification is sent to the worker OP through the TP (step ST37). When the determination unit 204 determines in step ST23 that the nozzle replacement table 31 is not to be removed, the second processing unit 203 starts the separation operation without causing the replacement table holding unit 32 to remove the nozzle replacement table 31. Then, the trolley lock unit 11R releases the lock of the feeder trolley 14 (step ST36).

  When the lock of the trolley lock unit 11R is released in step ST36, the second notification unit 202 notifies the automatic transport system of the completion of the lock release through the information management unit 205 (hereinafter, referred to as lock release notification). (Step ST38). Then, upon receiving the lock release notification, the first notification unit 821 of the management device 82 instructs the automatic transport vehicle 81 to separate the feeder truck 14 (dolly separation) (step ST39). The automatic transport vehicle 81 that has received the instruction to separate the carts catches the feeder carts 14 by lifting them off the floor or the like, and moves away from the component mounting apparatus 1 in a state where the feeder carts 14 are lifted off the floor. The vehicle travels (step ST40). Thereby, the separating operation for separating the feeder cart 14 from the base 11 is completed.

  As described above, in the work system 83 including the mounting system and the automatic transport system, the management device 82 controls the control device before the automatic transport vehicle 81 transports the feeder vehicle 14 and separates the feeder vehicle 14 from the base 11. 200 determines whether or not the nozzle exchange table 31 held by the exchange table holder 32 is to be removed from the exchange table holder 32. If the nozzle exchange table 31 is to be removed, the nozzle exchange table 32 is attached to the exchange table holder 32. If the feeder truck 14 is unlocked by the bogie lock unit 11R after removing the base 31 and placed on the mounting base 36, and the nozzle exchanging base 31 is not removed, the nozzle exchanging base 31 is attached to the exchanging base holding unit 32. The lock of the feeder cart 14 is released by the cart lock section 11R without removing the feeder cart.

  FIG. 28 shows an operation flow when the feeder cart 14 is connected to the base 11 by the automatic carrier 81 and the nozzle exchange table 31 is set on the base 11.

The arrival at the work standby position is detected (step ST46). When the second processing unit 203 detects that the feeder trolley 14 has reached the connection work standby position, the second locker 11R locks the feeder trolley 14 to connect to the base 11 (step ST50). Thereby, the connection operation of the feeder cart 14 is completed. After that, the second processing unit 203 operates the elevating cylinder 54 of the exchange table holding unit 32 to cause the exchange table holding unit 32 to hold the nozzle exchange table 31 (step ST51). Thus, the installation of the nozzle replacement table 31 on the base 11 is completed. If the feeder cart 14 to which the replacement nozzle exchange table 31 is not set is connected, step ST51 is skipped.

  When the exchange table holding unit 32 holds the nozzle exchange table 31, the second notification unit 202 notifies the automatic transport system of the completion of connection indicating that the connection work of the feeder cart 14 is completed (step ST52). The first processing unit 822 that has received the notification of the completion of the connection instructs the automatic transport vehicle 81 to leave (step ST53).
