FIG. 1 is an explanatory drawing of the component mounter 10, FIG. 2 is an explanatory drawing of the component mounter 10 with the feeder setting table 40 removed, FIG. 3 is an explanatory drawing of the feeder 30 and the feeder setting table 40, FIGS. 4 and 5 are side view and perspective view when looking at the periphery of the left moving mechanism 50 from the right side, FIG. 6 is a perspective view of the moving mechanism 50, FIGS. 7 and 8 are partial plan views of the component mounter 10 before and after setting the feeder setting table 40, FIG. 9 is an operation explanatory drawing of the lock mechanism 60, FIG. 10 is an explanatory drawing of the door part 80, and FIG. 11 is a block diagram showing the electrical connection relationship of the component mounter 10. Note that the left - right direction (X - axis direction), front - rear direction (Y - axis direction), and up - down direction (Z - axis direction) are as shown in FIGS. 1 to 10 (in FIGS. 4, 9, 10, 12, the left - right direction is perpendicular to the paper surface, and in FIGS. 7, 8, 13, the up - down direction is perpendicular to the paper surface).

[0011] As shown in FIGS. 1 and 2, the component mounter 10 has a mounter main body 10a provided on a base 10b, and the entire mounter main body 10a is covered by a housing 24. The mounter main body 10a includes a substrate transfer device 11 for transferring a substrate S, a head 12 having a suction nozzle 13 for sucking components, a head moving device 14 for moving the head 12 in the X - axis direction and the Y - axis direction, a feeder 30, a moving mechanism 50, a lock mechanism 60, a monitoring mechanism 70, and a door part 80. In addition to these, the mounter main body 10a also includes a parts camera 15 for imaging the suction posture of the components sucked by the suction nozzle 13, etc.

[0012] The substrate transfer device 11 includes a pair of conveyor rails arranged at intervals in the Y-axis direction, and by driving the pair of conveyor rails, the substrate S is transferred from left to right (transfer direction) in FIGS. 1 and 2.

[0013] The head 12 includes a Z-axis actuator 23 (see FIG. 11) that moves the suction nozzle 13 in the Z-axis (vertical) direction, a θ-axis actuator 25 (see FIG. 11) that rotates the suction nozzle 13 around the Z-axis, and a mark camera 29 for imaging the substrate S. The head 12 can adsorb components by applying negative pressure to the suction port by communicating a negative pressure source with the suction port of the suction nozzle 13. Also, the head 12 can release the adsorption of components by applying positive pressure to the suction port by communicating a positive pressure source with the suction port of the suction nozzle 13.

[0014] The head moving device 14 includes a pair of X-axis guide rails 17, an X-axis slider 18, an X-axis actuator 19 (see FIG. 11), a pair of Y-axis guide rails 20, a Y-axis slider 21, and a Y-axis actuator 22 (see FIG. 11). The pair of Y-axis guide rails 20 are installed on the upper stage of the housing 24 so as to extend parallel to each other in the Y-axis direction. The Y-axis slider 21 is bridged over the pair of Y-axis guide rails 20 and moves in the Y-axis direction along the Y-axis guide rails 20 by the drive of the Y-axis actuator 22. The pair of X-axis guide rails 17 are installed on the front surface of the Y-axis slider 21 so as to extend parallel to each other in the X-axis direction. The X-axis slider 18 is bridged over the pair of X-axis guide rails 17 and moves in the X-axis direction along the X-axis guide rails 17 by the drive of the X-axis actuator 19. The head 12 is attached to the X-axis slider 18, and the head moving device 14 moves the head 12 in the X-axis direction and the Y-axis direction by moving the X-axis slider 18 and the Y-axis slider 21.

[0015] As shown in FIG. 3, the feeder 30 includes, for example, a tape reel 34 around which a carrier tape 35 containing components at predetermined intervals is wound, and a tape feeding mechanism 36 that pulls out the carrier tape 35 from the tape reel 34 by driving a drive motor and feeds it to a component supply position. The feeder 30 is detachably held in a plurality of slots 42 provided in the feeder setting base 40. The slot 42 is a reverse T-shaped groove extending in the front-rear direction, and the T-shaped rail 31 of the feeder 30 is inserted therein. A clamp groove 43 is provided in the middle of the slot 42. The feeder setting base 40 has a vertical wall at the rear end. A connector 45 is provided at a position corresponding to each slot 42 on this vertical wall, and positioning holes 44, 44 are provided above and below the connector 45. When the rail 31 of the feeder 30 is inserted into the slot 42 from the front to the rear, a clamp member (not shown) provided on the lower surface of the feeder 30 fits into the clamp groove 43. As a result, the feeder 30 is supported in a vertical position in the slot 42, and the front-rear position is determined by the clamp member and the clamp groove 43. In addition, the positioning pins 32, 32 of the feeder 30 fit into the positioning holes 44, 44 of the feeder setting base 40, and the connector 33 of the feeder 30 is electrically connected to the connector 45 of the feeder setting base 40.

[0016] As shown in FIGS. 4 to 8, the moving mechanism 50 includes a guide rail 51 and a slider 52. As shown in FIGS. 7 and 8, the moving mechanism 50 is provided one on each of the left side and the right side of the feeder arrangement space 26 with the feeder arrangement space 26 interposed therebetween.

[0017] The guide rails 51 on both the left and right sides are attached to a frame member 53 extending in the front-rear direction (Y-axis direction) so as to be parallel to each other with the feeder placement space 26 therebetween. The frame member 53 is fixed to the base 10b (see FIG. 1). The slider 52 is attached so as to be movable in the front-rear direction (Y-axis direction) along the guide rail 51. The front portions of the sliders 52 on both the left and right sides are connected by a front-side connecting member 54, and the rear portions are connected by a rear-side connecting member 55. As shown in FIGS. 4 to 6, a notch (engaged portion) 52a that can engage with a hook (engaging portion) 61a of a mechanical lock 61 described later is formed in the front lower portion of each slider 52.

[0018] As shown in FIGS. 4 to 8, the locking mechanism 60 is provided in front of the left slider 52 and in front of the right slider 52. As shown in FIG. 5, the locking mechanism 60 includes a mechanical lock 61 and a lever 63.

[0019] The mechanical lock 61 is a rod swingably attached about a shaft 62, has a hook 61a as an engaging portion at the rear end, and has a handle portion 61b of the mechanical lock 61 at the front end. The shaft 62 is attached to a support member 10c fixed to the base 10b (see FIG. 1). As shown in FIGS. 9A and 9B, the hook 61a is provided so as to be movable between a regulation release position P1 and a regulation position P2 having an up-down relationship. The mechanical lock 61 is configured such that the hook 61a does not go above the regulation position P2 by a stopper (not shown). When positioned at the regulation position P2, as shown in FIG. 9B, the hook 61a engages with the notch 52a of the slider 52 to lock the slider 52 at a predetermined position T and regulate the movement of the slider 52. On the other hand, when positioned at the regulation release position P1, as shown in FIG. 9A, the hook 61a disengages from the notch 52a of the slider 52 to allow the slider 52 to move rearward. The hook 61a of the mechanical lock 61 is biased upward by the elastic force of a spring 64. Therefore, the hook 61a is normally positioned at the regulation position P2.

[0020] As shown in FIG. 5, the lever 63 is a plate-shaped member extending in the vertical direction and is provided in front of the mechanical lock 61. The lever 63 is a member for operating the handle portion 61b of the mechanical lock 61. The lever 63 has an elongated hole 63b, a mechanical lock insertion space 63c, a gripping portion 63d, and a protrusion 63e. The elongated hole 63b is a hole elongated in the vertical direction and penetrates the lever 63 in the left-right direction. The mechanical lock insertion space 63c is an internal space when the lower part of the lever 63 is bent into a U-shape. The handle portion 61b of the mechanical lock 61 is inserted into the mechanical lock insertion space 63c. The gripping portion 63d is a member gripped by the operator and extends horizontally forward at the upper part of the lever 63. The protrusion 63e is disposed at the uppermost end of the lever 63. The lever 63 is attached to be vertically movable by a mounting cover 65. The mounting cover 65 is fixed to the support member 10c by a pair of upper and lower shafts 65a, 65b. The shafts 65a, 65b penetrate the elongated hole 63b in the left-right direction and are attached to the support member 10c. Also, the vertical interval between the shafts 65a, 65b is set smaller than the vertical length of the elongated hole 63b. Therefore, the lever 63 can move vertically between a position where the lever 63 is lifted so that the lower end of the elongated hole 63b contacts the shaft 65b (referred to as the upper position Q1, see FIG. 9A) and a position where the lever 63 is pushed down so that the upper end of the elongated hole 63b contacts the shaft 65a (referred to as the lower position Q2, see FIG. 9B). The lever 63 is normally positioned at the lower position Q2 by its own weight and the elastic force of the spring 64. At this time, the hook 61a of the mechanical lock 61 is lifted upward by the elastic force of the spring 64 and positioned at the restricted position P2. On the other hand, when the operator grips the gripping portion 63d and moves the lever 63 from the lower position Q2 toward the upper position Q1, the handle portion 61b of the mechanical lock 61 is lifted by the lever 63. Therefore, the hook 61a is pushed downward against the elastic force of the spring 64 and positioned at the regulation release position P1.

[0021] As shown in FIG. 6, the monitoring mechanism 70 has a flap member 74, a detected portion 71, and a detection portion 72.

[0022] As shown in FIG. 2, the flap member 74 is a plate-like bridging member (corresponding to the specific member of the present invention) extending in the X-axis direction and spanning the feeder arrangement space 26. The flap member 74 is rotatably attached to the rear end of the rear-side connecting member 55 via a hinge 73. Thus, since the flap member 74 is attached to the slider 52 via the rear-side connecting member 55, it can move as the slider 52 moves. When the slider 52 is positioned at the predetermined position T, the flap member 74 is arranged at a position that obstructs the maintenance of the feeder arrangement space 26. When the feeder setting table 40 on which the feeder 30 is set is arranged in the feeder arrangement space 26, the flap member 74 is arranged slightly above the feeder 30. Further, as shown in FIG. 6, the flap member 74 is positioned by a stopper so as to be in a predetermined posture (horizontal posture) with respect to the rear-side connecting member 55, but when pushed up from below, it rotates upward about the hinge 73, and when the upward push is released, it returns to the predetermined posture.

[0023] The detected parts 71 are dogs integrated with the left and right ends of the lower surface of the flap member 74. The detected parts 71 move in the front-rear direction as the slider 52 moves, and can rotate in the vertical direction about the hinge 73 as the flap member 74 rotates.

[0024] The detection unit 72 is an optical sensor in which a light-emitting element and a light-receiving element are arranged to face each other with a gap in the left-right direction therebetween. As shown in FIG. 6, the detection unit 72 is attached to a detection unit attachment member 75 provided on the base 10b (see FIG. 1) independently of the slider 52. When the slider 52 is positioned at the predetermined position T and the flap member 74 is not pushed up from below and is in a predetermined posture, the detected portion 71 is disposed non-contactingly in the gap between the light-emitting element and the light-receiving element of the detection unit 72. Therefore, the light emitted from the light-emitting element is blocked by the detected portion 71 and does not reach the light-receiving element (light-shielded state). At this time, the signal of the detection unit 72 is off. On the other hand, when the flap member 74 is pushed up from below in this state, the detected portion 71 rotates upward and exits from between the light-emitting element and the light-receiving element of the detection unit 72. Therefore, the light emitted from the light-emitting element reaches the light-receiving element without being blocked by the detected portion 71 (light-emitting state). The signal of the detection unit 72 at this time is on. Further, when the slider 52 moves backward from the predetermined position T, the detected portion 71 exits from the gap between the light-emitting element and the light-receiving element of the detection unit 72, so the signal of the detection unit 72 becomes on. The detection unit 72 outputs a signal to the control device 90 (see FIG. 11).

[0025] As shown in FIG. 1, the door portion 80 is provided on the front surface of the housing 24. As shown in FIG. 10, the door portion 80 is provided so as to be movable between an open position R1 and a closed position R2 about a shaft 81 that extends horizontally in the left - right direction. The door portion 80 can open and close the feeder placement space 26. When the door portion 80 is closed, the operation of the lever 63 (that is, the operation of moving the lever 63 from the lower position Q2 to the upper position Q1, see FIG. 9) that releases the lock of the slider 52 by the mechanical lock 61 is physically restricted. Specifically, even if an attempt is made to move the lever 63 from the lower position Q2 to the upper position Q1, the lower end of the door portion 80 hits the upper end of the protrusion 63e of the lever 63, so the upward movement of the lever 63 is blocked. On the other hand, when the door portion 80 is open, the operation of the lever 63 that releases the lock of the slider 52 by the mechanical lock 61 is permitted. Specifically, since the lower end of the door portion 80 positioned at the open position R1 is at a position separated from the upper end of the protrusion 63e of the lever 63, the upward movement of the lever 63 is permitted.

[0026] As shown in FIG. 11, the control device 90 is configured as a microprocessor centered on the CPU 91. In addition to the CPU 91, it includes a ROM 92, a storage 93 (for example, an HDD or an SSD), and a RAM 94. The control device 90 outputs a control signal to the feeder 30, outputs a control signal to the substrate transfer device 11, outputs a control signal to the head 12, and outputs a control signal to the parts camera 15. Also, the control device 90 inputs various signals from the head movement device 14, inputs an image signal from the mark camera 29, inputs an image signal from the parts camera 15, and inputs a signal from the detection unit 72 of the monitoring mechanism 70.

[0027] The component mounting operation by the component mounter 10 configured in this way will be described. The routine of the component mounting operation is stored in the storage 93 and is executed by the CPU 91. In this embodiment, it is assumed that the feeder set stand 40 with the necessary feeders 30 set is arranged in advance in the feeder placement space 26 of the component mounter 10.

[0028] Before executing the component mounting operation, the operator checks that the door portion 80 is positioned at the closed position R2 and that no error message is being reported from the component mounter 10, and then commands the component mounter 10 to start the component mounting operation. The error message is displayed on a display device (not shown) of the component mounter 10 when the slider 52 is moving backward from the predetermined state T or when the flap member 74 is being pushed up. Specifically, if an OFF signal is input from the detection unit 72, the CPU 91 does not report an error message because the slider 52 is positioned at the predetermined position T and the flap member 74 is not being pushed up. On the other hand, if an ON signal is input from the detection unit 72, the CPU 91 displays an error message on the display device because the slider 52 is moving backward from the predetermined position T or the flap member 74 is being pushed up.

[0029] When a command for the component mounting operation is input, the CPU 91 causes the suction nozzle 13 of the head 12 to suck a component supplied from the feeder 30. Specifically, the CPU 91 controls the X-axis actuator 19 and the Y-axis actuator 22 to move the suction nozzle 13 directly above the component suction position of the desired component. Next, the CPU 91 controls the Z-axis actuator 23 and a negative pressure source (not shown) to lower the suction nozzle 13 and supply negative pressure to the suction nozzle 13. As a result, the desired component is sucked to the tip of the suction nozzle 13. Thereafter, the CPU 91 raises the suction nozzle 13 and controls the X-axis actuator 19 and the Y-axis actuator 22 to move the suction nozzle 13 with the component sucked to its tip above the target mounting position on the substrate S. Then, at the predetermined position, the CPU 91 lowers the suction nozzle 13 and controls a positive pressure source (not shown) to supply atmospheric pressure to the suction nozzle 13. As a result, the component adsorbed to the suction nozzle 13 is separated and mounted at a predetermined position on the substrate S. For other components to be mounted on the substrate S, they are similarly mounted on the substrate S. When the mounting of all components is completed, the CPU 91 controls the substrate transfer device 11 to send out the substrate S to the downstream side. When the component mounter 10 is performing the mounting operation, an interlock (not shown) provided on the door portion 80 operates to restrict the opening and closing of the door portion 80. Therefore, when the component mounter 10 is performing the mounting operation, the door portion 80 is positioned at the closed position R2. Accordingly, when the component mounter 10 is performing the mounting operation, it becomes physically impossible to operate the lever 63 such that the lock of the slider 52 is released by the mechanical lock 61, and the movement of the slider 52 can be prevented.

[0030] Next, during the operation of the component mounter 10, the operator inserts a feeder 30 (referred to as the feeder 30 to be inserted) into a slot 42 where the feeder 30 is not set (referred to as the empty slot 42). First, the operator prepares the feeder 30 to be inserted. Then, with the door portion 80 positioned at the closed position R2 and the slider 52 positioned at the predetermined position T by the mechanical lock 61, the operator inserts the feeder 30 to be inserted into the empty slot 42. Then, the operator moves the feeder 30 to be inserted backward to connect the connector 33 and the connector 45.

[0031] When the operator moves the feeder 30 to be inserted backward while the rail 31 of the feeder 30 to be inserted does not fit well into the empty slot 42 during the insertion operation, the feeder 30 to be inserted rises with respect to the feeder setting base 40. Then, the monitoring mechanism 70 detects the rising of the feeder 30 to be inserted. That is, when the feeder 30 is rising, the feeder 30 to be inserted contacts the lower surface of the flap member 74 and pushes up the flap member 74 from below as shown in FIG. 12A. As a result, the flap member 74 rotates upward. As the flap member 74 rotates upward, the detected portion 71 also rotates upward and passes through the gap between the light projecting element and the light receiving element of the detecting portion 72. At this time, the detecting portion 72 enters a light projecting state and outputs an on signal to the control device 90. The CPU 91 that has received the on signal from the detecting portion 72 displays an error message on a display device (not shown). The operator who sees the error message notices that the feeder 30 is not inserted correctly, pulls out the feeder 30 being inserted, and then performs the insertion operation of the feeder 30 again. On the other hand, when the feeder 30 to be inserted is not rising, the feeder 30 to be inserted does not contact the lower surface of the flap member 74 and does not push up the flap member 74 as shown in FIG. 12B. Therefore, the flap member 74 maintains a predetermined posture with respect to the rear side connecting member 55. Accordingly, the detected portion 71 maintains a state of being disposed between the light projecting element and the light receiving element of the detecting portion 72. At this time, the detecting portion 72 maintains a light shielding state and outputs an off signal to the control device 90, and the CPU 91 does not display an error message on the display device.

[0032] Next, the maintenance of the feeder placement space 26 of the component mounter 10 will be described. Maintenance refers to operations such as adjusting or replacing various members provided on the upper surface of the base 10b that forms the feeder placement space 26. Maintenance is executed by an operator after the component mounting operation is completed. In maintenance, the operator first removes the feeder set stand 40 from the component mounter 10. Next, the operator moves the door portion 80 to the open position R1, grips the gripping portion 63d of the lever 63, and moves the lever 63 to the upper position Q1. As a result, the hook 61a of the mechanical lock 61 moves to the regulation release position P1, and the lock of the slider 52 is released. Next, as shown in FIG. 13, the operator moves the front-side connecting member 54, the rear-side connecting member 55, and the flap member 74 integrated with the slider 52 to positions where they do not interfere with maintenance. Then, the operator performs maintenance on the feeder placement space 26. After the maintenance is completed, the operator moves the slider 52 to the predetermined position T. Then, the hook 61a of the mechanical lock 61 is positioned at the regulation position P2, and the slider 52 is locked at the predetermined position T. Then, the operator moves the door portion 80 to the closed position R2.

[0033] In the component mounter 10 described in detail above, the flap member 74 provided in the monitoring mechanism 70 capable of monitoring the lifting of the feeder 30 moves in accordance with the movement of the slider 52. The flap member 74 is normally disposed at a position that obstructs the maintenance of the feeder placement space 26 (see FIG. 7). Therefore, for example, when performing maintenance on the feeder placement space 26, etc., by pre-moving the flap member 74 together with the slider 52 to a position where it does not interfere with maintenance (see FIG. 13), it is possible to facilitate maintenance.

[0034] Further, the monitoring mechanism 70 includes a flap member 74, a detected portion 71 integrated with the flap member 74, and a detection portion 72 provided independently of the slider 52 and capable of detecting the detected portion 71. The flap member 74 is arranged such that when the slider 52 is positioned at the predetermined position T, if the feeder 30 arranged in the feeder arrangement space 26 rises, the flap member 74 is pushed up by the rising feeder 30. The detection portion 72 is capable of detecting that the detected portion 71 has moved along with the flap member 74 pushed up by the feeder 30. Therefore, the rising of the feeder 30 can be monitored using the flap member 74. The detection portion 72 is further capable of detecting that the detected portion 71 has moved as the slider 52 moves from the predetermined position T. That is, in addition to being able to detect that the detected portion 71 has moved along with the flap member 74 pushed up by the feeder 30, the detection portion 72 is also capable of detecting that the detected portion 71 has moved as the slider 52 moves from the predetermined position T. Therefore, the rising of the feeder 30 and the movement of the slider 52 can be monitored by one detection portion 72.

[0035] Furthermore, the component mounter 10 includes a mechanical lock 61 capable of locking the slider 52 at a predetermined position T, a lever 63 operable to operate the mechanical lock 61, and a door portion 80 provided to be openable and closable. When closed, the door portion 80 physically restricts the operation of the lever 63 such that the locking of the slider 52 by the mechanical lock 61 is released. When open, the door portion 80 allows the operation of the lever 63 such that the locking of the slider 52 by the mechanical lock 61 is released. For example, when the component mounter 10 is operated with the slider 52 locked by the mechanical lock 61 and the door portion 80 closed, the mechanical lock 61 locks the slider 52 to restrict movement, and the door portion 80 restricts the operation of the lever 63 that releases the locking of the slider 52. Therefore, there is no risk that the slider 52 will move due to some cause and adversely affect the component mounting operation or the like. Also, for example, when the slider 52 cannot be locked at the predetermined position T by the mechanical lock 61 and the slider 52 moves, the monitoring mechanism 70 monitors whether the slider 52 has moved from the predetermined position T based on whether the detection unit 72 has detected the detected unit 71. That is, when the slider 52 moves backward from the predetermined position T, the detected unit 71 moves backward as the slider 52 moves. At this time, the detected unit 71 escapes from the gap between the light emitting element and the light receiving element of the detection unit 72. Therefore, the detection unit 72 enters a light emitting state and outputs an on signal to the control device 90.

[0036] Furthermore, a pair of guide rails 51 are provided in parallel with each other with the feeder arrangement space 26 therebetween. One slider 52 is provided for each of the guide rails 51, and one mechanical lock 61 is provided for each of the sliders 52. Therefore, the flap member 74 and the like can be moved smoothly. Also, one lever 63 is provided for each of the mechanical locks 61. Therefore, the operator can easily release each mechanical lock 61 using the lever 63.

[0037] It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that the present invention can be implemented in various forms as long as it belongs to the technical scope of the present invention.

[0038] For example, in the above-described embodiment, the door portion 80 is provided to be openable and closable between the open position R1 and the closed position R2 around the shaft 81, but it is not limited thereto. For example, in the above-described embodiment, the door portion 80 may be provided to be vertically movable.

[0039] In the above-described embodiment, an optical sensor is adopted as the detection unit 72, but it is not limited thereto.
