When the operator inserts the feeder carriage 21 into one of the four carriage insertion spaces 11S of the base 11, the position of the carriage insertion space 11S on the base 11 is set using the operation section 18b of the touch panel 18. Specify (input).

Before the operator performs the above operation, that is, before the feeder truck 21 is inserted into the truck insertion space 11S, the entry detector 65 of the truck insertion space 11S is off, and the shutter 17 is positioned at the closed position. there is Further, the lock arm 61a of the carriage lock portion 61 is positioned at the unlocked position, and the connection arm 64a of the carriage connection portion 64 is positioned at the non-connected position (FIG. 19).

When the control unit 40 detects that the operator designates the position of the carriage insertion space 11S through the touch panel 18 (step ST1 in FIG. 18), the designated carriage insertion space 11S is not connected to the carriage. It is determined whether or not it is in a state (a state in which the feeder carriage 21 is not connected). When the control unit 40 determines that the specified carriage insertion space 11S is in the carriage unconnected state, the control unit 40 instructs the operator through the display unit 18a of the touch panel 18 to insert the feeder into the specified carriage insertion space 11S. The insertion of the cart 21 is instructed (step ST2).

When the operator receives an instruction to insert the feeder carriage 21 from the control unit 40 through the touch panel 18, the operator operates the left and right handles 53 provided on the feeder carriage 21 (arrow P1 shown in FIG. 19), and the carriage side connector 56 is connected to the base. The feeder truck 21 is caused to travel in a direction approaching the platform-side connector 67, and the feeder truck 21 is inserted into the truck insertion space 11S. Then, the feeder carriage 21 is operated until the left and right cam followers 55 on the feeder carriage 21 side come into contact with the ends (inclined surfaces) of the left and right retraction guides 62 on the base 11 side, and the feeder carriage 21 is advanced to the reference position. (FIG. 19→FIG. 20).

The operator releases the handle 53 after the feeder carriage 21 is advanced to the reference position. When the feeder truck 21 has entered the reference position, the operating piece 65a of the entry detector 65 is operated by the side surface 52S of the upper truck portion 52 and is turned on from off (FIG. 17(a)→FIG. 17(b). )).

After instructing the operator to insert the feeder trolley 21 into the trolley insertion space 11S in step ST2, the control unit 40 monitors the timing at which the entry detector 65 turns on from off in the trolley entry monitoring unit 40c (step ST3). ). Then, when it is detected that the entry detector 65 has turned on from off, the control unit 40 operates the lock arm drive cylinder 61b to swing the lock arm 61a from the unlocked position to the locked position (Fig. 20 → Figure 21).

When the lock arm 61a swings from the unlocked position to the locked position, the left and right lock arms 61a change from the horizontal posture to the vertical posture, and are positioned outside the left and right protrusions 54 in the Y-axis direction (FIG. 21). As a result, the left and right protrusions 54 are locked by the left and right lock arms 61a (that is, the feeder truck 21 is locked by the truck lock portion 61) (step ST4). When the feeder carriage 21 is locked by the carriage locking portion 61 in this manner, the operator cannot pull out the feeder carriage 21 from the carriage insertion space 11S.

When the feeder carriage 21 is locked to the base 11 by the carriage lock section 61, the control section 40 operates the connector moving cylinder 66b to move the carriage detection connector 66a as the carriage detector to the projecting position (step ST5). 21→22). Here, when the feeder truck 21 has been inserted into the truck insertion space 11S and the entry detector 65 has been switched from off to on (that is, when the feeder truck 21 has entered the reference position), the truck The detection connector 66 a is horizontally connected (fitted) to the carriage-side connector 56 provided on the feeder carriage 21 .

After projecting the truck detection connector 66a, the control unit 40 determines whether the feeder truck 21 can be detected within a predetermined time determined in consideration of the time required for the truck detection connector 66a to connect to the truck side connector 56. (step ST6). Specifically, a signal is transmitted to the feeder truck 21 side for a predetermined time, and if the signal exchange with the feeder truck 21 side succeeds within the predetermined time, the feeder truck 21 can be detected. On the other hand, if the signal exchange with the feeder truck 21 side is not successful within the predetermined time, it is assumed that the feeder truck 21 could not be detected.

If the controller 40 fails to detect the feeder truck 21 within the predetermined time in step ST6, it operates the connector moving cylinder 66b to separate the truck detection connector 66a from the truck side connector 56 and position it at the storage position. After that, the notification section 18c of the touch panel 18 displays that fact to the operator (error display) (step ST7). Then, returning to step ST2, the operator is again instructed to insert the feeder carriage 21 into the carriage insertion space 11S via the display section 18a of the touch panel 18. FIG. As an example of the case where the feeder truck 21 cannot be detected in step ST6 even though the entry detector 65 is turned on in step ST3, an operator enters the truck insertion space 11S where the feeder truck 21 is not inserted. comes in and turns the entry detector 65 into a detection state (on).

On the other hand, when the feeder truck 21 is detected in step ST6, the control unit 40 operates the connector moving cylinder 66b to separate the truck detection connector 66a as a truck detector from the truck side connector 56 and move it to the storage position. Position (step ST8, FIG. 22→FIG. 23). When the carriage-side connector 56 is positioned at the retracted position, the control section 40 operates the shutter driving section 33 from the shutter control section 40b to position the shutter 17, which is positioned at the closed position, at the open position (step ST9. FIG. 22→Fig. 23).

After moving the shutter 17 from the closed position to the open position, the control unit 40 operates the carriage connecting part 64, operates the left and right connecting arm drive cylinders 64b, and disconnects the left and right connecting arms 64a. It is swung from the position to the connecting position (Fig. 23->Fig. 24->Fig. 25). In the process in which the left and right connecting arms 64a swing from the non-connecting position to the connecting position, the left and right cam followers 55 on the feeder carriage 21 side are lifted and drawn toward the base 11 side. As a result, the left and right cam followers 55 ride on the horizontal upper surface from the inclined surfaces of the left and right retraction guides 62 . After riding on the horizontal upper surfaces of the left and right retraction guides 62, the left and right cam followers 55 move (roll) horizontally toward the base 11 (FIGS. 23→24→25). While the shutter 17 is positioned at the open position, the controller 40 operates the carriage connecting portion 64, operates the left and right connecting arm drive cylinders 64b, and moves the left and right connecting arms 64a from the non-connecting position to the connecting position. 23→FIG. 24→FIG. 25), and in the process of swinging the left and right connecting arms 64a from the non-connecting position to the connecting position, the left and right cam followers 55 on the feeder carriage 21 side are lifted and moved to the base 11 side. You may make it draw to.

By the movement of the left and right cam followers 55 as described above (movement along the shape of the inclined surface and the upper surface of the left and right retraction guides 62), the carriage upper part 52 is lifted upward by the left and right connecting arms 64a, and moves toward the base 11 side. After approaching , it moves horizontally to approach the base 11 . Since the left and right connecting arms 64a in the vertical posture at the connecting position hold the left and right cam followers 55 in a state of being drawn toward the base 11, the left and right cam followers 55 are locked by the left and right connecting arms 64a. The feeder truck 21 is connected to the base 11 by the truck connecting portion 64 (step ST10).

Here, when the left and right cam followers 55 move (roll) on the horizontal upper surface through the inclined surfaces of the left and right retraction guides 62, the biasing spring 63 is compressed by the feeder carriage 21 through the cam followers 55 (FIG. 26). (a)→FIG. 26(b)→FIG. 26(c)). Therefore, while the left and right connecting arms 64a are locking the left and right cam followers 55, the left and right cam followers 55 are not pushed outward (in the direction of being pushed out of the carriage insertion space 11S) by the elastic force of the left and right urging springs 63. A biasing force acts.

As described above, in the process in which the carriage upper portion 52 moves horizontally to approach the base 11, the carriage-side connector 56 is horizontally fitted and connected to the base-side connector 67 (FIG. 26(a)→FIG. 26(b)→FIG. 26(c)). As a result, the carriage-side connector 56 and the base-side connector 67 are connected (FIGS. 24 to 25), and the connection of the feeder carriage 21 to the base 11 is completed. When the feeder carriage 21 is connected to the base 11, the end of the component supply feeder 22 attached to the feeder carriage 21 on the side of the base 11 is in an open state because the shutter 17 is positioned at the open position. It advances into the area of the opening SP of the work space 11R (FIG. 25).

When the connection of the feeder carriage 21 to the base 11 is completed by the operation of the carriage connecting portion 64, the control section 40 transmits a signal to the feeder carriage 21 side for a predetermined period of time. Try to see if you can interact with If the signal exchange with the feeder carriage 21 is successful within the predetermined time, it is determined that the communication state with the feeder carriage 21 is normal, and the communication with the feeder carriage 21 is established within the predetermined time. If the signal exchange is not successful, it is determined that the communication state with the feeder carriage 21 is not normal (step ST11).

If the control unit 40 determines in step ST11 that the communication state with the feeder carriage 21 is normal, it ends the carriage connection processing. On the other hand, when it is determined that the communication state with the feeder truck 21 is not normal, an error is displayed to the operator via the display section 18a of the touch panel 18 (step ST12), and the truck connection processing is terminated. do. This completes the carriage connection work.

Next, the flow of processing (truck extraction processing) performed by the control unit 40 when the truck extraction work is performed will be described with reference to the flowchart of FIG. 27 . When the operator pulls out the feeder carriage 21 from one of the four carriage insertion spaces 11S of the base 11, the operator specifies the position of the carriage insertion space 11S on the base 11 from the operation section 18b of the touch panel 18. (input.

Before the operator performs the above operation, that is, before the feeder truck 21 is pulled out of the truck insertion space 11S, the entry detector 65 of the truck insertion space 11S is on and the shutter 17 is at the open position. Further, the lock arm 61a of the truck lock portion 61 is positioned at the lock position, and the connection arm 64a of the truck connection portion 64 is positioned at the connection position (FIG. 25).

When the controller 40 detects that the operator has designated the position of the carriage insertion space 11S through the touch panel 18 (step ST21 in FIG. 27), the designated carriage insertion space 11S is in the carriage connected state. It is determined whether or not (the feeder truck 21 is connected). Then, when the controller 40 determines that the designated truck insertion space 11S is in the truck-connected state, the controller 40 operates the connecting arm drive cylinder 64b to swing the connecting arm 64a from the connecting position to the non-connecting position. (Fig. 25→Fig. 28→Fig. 29).

The left and right cam followers 55 are unlocked when the left and right connecting arms 64a swing from the connecting position to the non-connecting position and take a horizontal posture. As a result, the left and right cam followers 55 are pushed outward (in the drawing direction of the feeder carriage 21) by the left and right urging springs 63, and the left and right cam followers 55 move (roll) outward on the upper surfaces of the left and right retraction guides 62. (FIG. 26(c)→FIG. 26(b)). During this time, the carriage upper portion 52 moves away from the base 11 in the horizontal direction, and the carriage-side connector 56 is disconnected from the base-side connector 67 to be disconnected (FIGS. 25 to 28).

The left and right cam followers 55 move outward on the upper surfaces of the left and right retraction guides 62, and are then separated from the ends (inclined surfaces) of the left and right retraction guides 62 (FIG. 26(b)→FIG. 26(a)). As a result, the carriage upper portion 52 descends by its own weight and is supported by the carriage lower portion 51 (FIGS. 28 to 29), and the feeder carriage 21 is disconnected from the base 11 (step ST22).

After the feeder carriage 21 is disconnected from the base 11 as described above, the control unit 40 operates the shutter driving unit 33 to move the shutter 17 from the open position to the closed position (step ST23). 29→30). Then, the lock arm drive cylinder 61b is operated to swing the lock arm 61a from the lock position to the unlock position (Fig. 30→Fig. 31).

When the left and right lock arms 61a are swung to the unlocked position and take the horizontal posture, the left and right protrusions 54 are unlocked, and the lock of the feeder carriage 21 by the carriage lock portion 61 is released (step ST24). When the lock of the feeder carriage 21 by the carriage lock section 61 is released, the control section 40 displays a message for allowing the removal of the feeder carriage 21 to the operator through the display section 18a of the touch panel 18 (step ST25), and starts the carriage removal process. finish.

When the operator receives a pull-out permission message from the control unit 40 through the touch panel 18, the operator operates the left and right handles 53 provided on the feeder truck 21 to pull out the feeder truck 21 from the truck insertion space 11S (FIGS. 31 to 32). Arrow P2 shown in FIG. 32). This completes the carriage extraction work.

Thus, in the component mounting apparatus 1 according to Embodiment 1, the state in which the feeder carriage 21 inserted into the carriage insertion space 11S of the base 11 has entered the reference position set with respect to the base 11 is detected by the entry detector. When detected by 65, a truck detection connector 66a, which is a truck detector, is protruded from the retracted position to the projecting position by a connector moving cylinder 66b, which is a truck detector moving means. When the feeder trolley 21 positioned at the reference position is detected by electrically detecting that the trolley detection connector 66a positioned at the projecting position is connected to the trolley side connector 56, the trolley A connecting portion 64 connects the feeder carriage 21 to the base 11 .

For this reason, for example, the entry detector 65 is erroneously operated while the feeder truck 21 is not inserted into the truck insertion space 11S. Even if detection information (on signal in this case) is outputted, the carriage connection part 64 does not operate in a state where the feeder carriage 21 is not actually inserted into the carriage insertion space 11S. Therefore, according to the component mounting apparatus 1 of Embodiment 1, it is possible to prevent the situation in which the carriage connecting portion 64 is operated even though the feeder carriage 21 is not inserted into the carriage insertion space 11S, thereby ensuring the safety of the operator. can be ensured.

Further, the shutter 17 for opening and closing the opening SP leading to the work space 11R formed by the base 11 and the cover member 11C provided on the base 11 is controlled by the control unit 40 to detect the carriage as a carriage detector. When the connector 66a detects the feeder truck 21, the closed opening SP is opened, and when the truck detector does not detect the feeder truck 21, the closed state of the opening SP is maintained. . For this reason, when the feeder carriage 21 is pulled out from the carriage insertion space 11S, the opening SP is closed by the shutter 17, and the operator cannot insert his or her hand into the work space 11R. can enhance sexuality.

In addition, since the inspection light 16L of the optical sensor 16 is not blocked by the shutter 17 regardless of the opening/closing state of the shutter 17 (FIGS. 9A and 9B), the feeder carriage 21 can be pulled out from one carriage insertion space 11S. , even if the shutter 17 corresponding to the carriage insertion space 11S is closed, the detection function of the optical sensor 16 (the function of detecting a state in which a part of the component supply feeder 22 is lifted from the normal position) is maintained. be. For this reason, when the feeder carriage 21 is pulled out from the carriage insertion space 11S, the opening SP is closed by the shutter 17, so that the feeder can be fed from one carriage insertion space 11S while the component mounting apparatus 1 is in operation. Even when the carriage 21 is pulled out, the component mounting apparatus 1 can continue to operate, and the productivity of the component mounting apparatus 1 can be improved.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. The component mounting apparatus 1 according to the second embodiment differs from the component mounting apparatus 1 according to the first embodiment in the configuration of the carriage detection section 66 and the system for detecting the feeder carriage 21 .

As shown in FIG. 33, the carriage detection unit 66 in the second embodiment is provided inside the base 11 as in the case of the first embodiment. As shown in FIGS. 34(a) and 34(b), the carriage detection unit 66 includes a switch unit 101 as a carriage detector and a switch unit moving cylinder 102 as carriage detector moving means. there is The switch portion moving cylinder 102 has its cylinder tube fixed to the base 11, and the end portion of the switch portion operating rod 102R, which is an operating rod, extends outward (outside in the Y-axis direction when viewed from the center of the base 11). placed in a facing position.

35(a) and 35(b), the switch portion 101 includes a switch base 111 attached to the end of the switch portion operating rod 102R, an operating piece support portion 112 provided on the upper portion of the switch base 111, an operation piece support An operation rod 113 supported in a posture extending in the Y-axis direction by a portion 112 , and a switch piece 114 having upper and lower ends connected to the operation rod 113 and the switch base 111 . A roller member 115 is provided at the outer end of the operating rod 113 .

When the switch portion moving cylinder 102 is actuated to operate the switch portion operating rod 102R, the switch portion 101 is guided by the movement guide 116 provided on the base 11 and moves in the Y-axis direction (FIG. 34(a)). → Fig. 34(b) or Fig. 34(b) → Fig. 34(a)). By moving the switch portion 101 in the Y-axis direction, the switch base 111 is moved by the roller member 115 provided at the tip end of the operation rod 113 (left side in FIGS. 35(a) and 35(b)). The roller member 115 moves between a retracted position (FIG. 34(a)) in which it is stored in the base 11 and an extended position (FIG. 34(b)) in which the roller member 115 extends outward from the base 11. As shown in FIG.

35(a) and 35(b), the operating rod 113 has a guide hole 117 which is an elongated hole extending in the Y-axis direction. The operation piece support portion 112 is provided with two support pins 118 aligned in the Y-axis direction, and these two support pins 118 are positioned inside the guide hole 117 . Therefore, the operating rod 113 can move freely in the Y-axis direction while maintaining a horizontal posture. 35(a) and 35(b) of the guide hole 117, and the left support pin 118 of the two support pins 118 contacts the "initial position" (Fig. 35). 35(a)) and the "maximum pushing position" (position shown in FIG. 35(b)) where the right support pin 118 of the two support pins 118 contacts the right end of the guide hole 117. It is movable between

35(a) and 35(b), the switch piece 114 extends vertically and has an elongated hole 119 at its upper portion. The lower end of the switch piece 114 is pivotally supported on the switch base 111 by a pivot pin 120 , and a pin 121 provided at the inner end of the operating rod 113 is positioned in the long hole 119 . Therefore, when the operating rod 113 moves in the Y-axis direction, the switch piece 114 swings around the pivot pin 120 so that the upper end side moves back and forth (FIG. 35(a)→FIG. 35(b) or FIG. 35(b)→FIG. 35(a)).

The switch piece 114 is biased by a biasing member 122 such as a coil spring provided in the switch base 111 in a direction to position the operating rod 113 at the initial position. Therefore, when nothing is in contact with the roller member 115, the operating rod 113 is positioned at the initial position. When the operating rod 113 is at the initial position, the switch piece 114 is in a vertically extending position, and the contact of the truck detection switch 123 provided inside the switch base 111 is turned "OFF" (FIG. 35). (a)). On the other hand, when the roller member 115 is pressed rightward in FIGS. 35(a) and 35(b). Then, when the inclination reaches a certain amount or more, the contact of the truck detection switch 123 is turned "on".

A carriage detection switch 123 in the switch base 111 is connected to the control section 40 , and an ON/OFF signal of the carriage detection switch 123 is input to the control section 40 . Therefore, the control unit 40 always grasps the ON/OFF state of the truck detection switch 123 .

34(a) and 34(b), the base 11 is provided with an operating rod return portion 11T. When the switch portion 101 is in the retracted position, the proximal end (the right side in FIGS. 35(a) and (b)) of the operating rod 113 is in contact with the operating rod return portion 11T. As a result, the operating rod 113 is always positioned at the initial position when the switch portion 101 is positioned at the retracted position. Therefore, when the switch section 101 is in the retracted position, the output of the switch section 101 (the truck detection switch 123) is always off.

When the feeder carriage 21 is inserted into the carriage insertion space 11S of the base 11 and the entry detector 65 is switched from OFF to ON with the switch section 101 positioned at the retracted position, the control section 40 causes the switch section moving cylinder 102 to move. 36(a)→FIG. 36(b). Here, when the feeder truck 21 has been inserted into the truck insertion space 11S and the entry detector 65 has been switched from off to on (that is, when the feeder truck 21 has entered the reference position), the operation The front end portion (roller member 115) of the rod 113 contacts the front surface 21F of the carriage upper portion 52 of the feeder carriage 21 (FIG. 36(b)), and the switch piece 114 is tilted (FIG. 36(b)→FIG. 36(c). ), the output of the switch unit 101 is switched from off to on.

In the second embodiment, the carriage detection determination section 40e provided in the control section 40 operates the switch section moving cylinder 102 to move the switch section 101 from the retracted position to the extended position. Then, it is determined whether the feeder truck 21 is positioned at the reference position based on whether the output from the switch section 101 (the truck detection switch 123) is switched from off to on. Specifically, when the output from the switch section 101 is switched between off and on within a predetermined time after the switch section 101 is positioned at the extended position, it is determined that the feeder carriage 21 is positioned at the reference position. If the output from the switch 101 remains off even after a predetermined time has elapsed after the switch 101 is positioned at the extended position, it is determined that the feeder carriage 21 is not positioned at the reference position.

After judging whether or not the feeder carriage 21 is positioned at the reference position by extending the switch portion 101 to the extended position, the control portion 40 operates the switch portion moving cylinder 102 to move the switch portion 101 to the retracted position. (FIG. 37(a)→FIG. 37(b)→FIG. 37(c)). When the feeder carriage 21 is positioned at the reference position and the roller member 115 is in contact with the front surface 21F of the feeder carriage 21, the operating rod 113 is biased until the switch section 101 is retracted to the retracted position. As the urging force of the member 122 returns the operating rod 113 to its vertically extended posture, it returns to its initial position. As a result, the output of the switch section 101 is switched from on to off. Then, when the truck detection determination unit 40e determines that the feeder truck 21 is positioned at the reference position, the truck connection control unit 40f of the control unit 40 prevents the output from the switch unit 101 from being switched from on to off. After waiting, the switch portion moving cylinder 102 is operated, and the feeder carriage 21 is connected to the base 11 by the carriage connecting portion 64 .

Here, as described above, when the switch portion 101 is stored in the retracted position, the proximal end portion of the operating rod 113 contacts the operating rod return portion 11T, and the operating rod 113 is always returned to the initial state. be For this reason, if the contact of the carriage detection switch 123 is welded in the ON state, the ON state of the switch unit 101 cannot be canceled by the biasing force of the biasing member 122 (the operating rod 113 does not return to the initial state). state), the operating rod 113 is returned to the initial state and the ON state of the switch portion 101 is canceled if the switch portion 101 is retracted to the retracted position.

Thus, in the component mounting apparatus 1 according to the second embodiment, the state in which the feeder carriage 21 inserted into the carriage insertion space 11S of the base 11 has entered the reference position set with respect to the base 11 is detected by the entry detector. When detected by 65, the switch section 101, which is the truck detector, is projected from the retracted position to the extended position by the switch section moving cylinder 102, which is the truck detector moving means. Then, when the operating rod 113 (roller member 115) of the switch portion 101 positioned at the extended position comes into contact with the front surface 21F of the feeder carriage 21 (by detecting the front surface 21F of the feeder carriage 21), it is positioned at the reference position. When the feeder trolley 21 is detected in a state where the feeder trolley 21 is in a state where the feeder trolley 21 is connected to the base 11 , the trolley connecting portion 64 connects the feeder trolley 21 to the base 11 .

In the component mounting apparatus 1 according to the second embodiment, the switch unit 101 as a truck detector mechanically detects the state in which the feeder truck 21 is positioned at the reference position by contact with the feeder truck 21. there is Therefore, as in the case of the first embodiment, the entry detector 65 is erroneously operated while the feeder truck 21 is not inserted into the truck insertion space 11S, and the entry detector 65 detects that the feeder truck 21 is the reference. Even if the detection information (in this case, an ON signal) detected when the vehicle is positioned at the position is output, the vehicle connecting portion 64 is not actually inserted into the vehicle insertion space 11S. will not work. Therefore, according to the component mounting apparatus 1 of the second embodiment, as in the case of the component mounting apparatus 1 of the first embodiment, even though the feeder carriage 21 is not inserted into the carriage insertion space 11S, the carriage connecting portion 64 is operation can be prevented, and the safety of the operator can be ensured.

Also in the second embodiment, the shutter 17 is controlled by the control unit 40 to open the closed opening SP when the switch unit 101, which is a truck detector, detects the feeder truck 21. When the switch unit 101 does not detect the feeder carriage 21, the closed state of the opening SP is maintained. Therefore, as in the case of the first embodiment, the opening SP is closed by the shutter 17 when the feeder carriage 21 is pulled out from the carriage insertion space 11S, and the operator inserts his/her hand into the work space 11R. work safety can be improved.

Although Embodiments 1 and 2 of the present invention have been described so far, the present invention is not limited to those described above, and various modifications and the like are possible. For example, in the above-described first embodiment, a connector for mutual communication (carry side connector 56 ) has been used, it is also possible to provide a dedicated connector on the feeder truck 21 only for connecting with the truck detection connector 66a and connect the truck detection connector 66a to this connector.

Further, in the first embodiment described above, when the control unit 40 detects that the truck detection connector 66a is connected to the truck side connector 56, the control unit 40 operates the connector moving cylinder 66b to connect the truck detection connector 66a to the truck side connector. 56 and moved to the storage position. This is because when the feeder carriage 21 is connected to the base 11, the feeder carriage 21 is lifted by the connection arm 64a. Therefore, when connecting the feeder carriage 21 to the base 11, if the connection arm 64a does not lift the feeder carriage 21 (the feeder carriage 21 is drawn horizontally), the carriage connected to the carriage side connector 56 is detected. Without separating the connector 66a from the carriage-side connector 56, the connector operating rod 66R of the connector moving cylinder 66b is accommodated in the cylinder tube as the feeder carriage 21 is drawn toward the base 11 by the connecting arm 64a. may In this case, the base-side connector 67 for mutual communication with the feeder truck 21 also functions as the truck detection connector 66a (the base-side connector 67 and the truck detection connector 66a are the same connector). ).

Further, the configuration of the switch unit 101 as the truck detector in the above-described second embodiment is merely an example. 21 can be detected. Note that the carriage detection unit 66 in Embodiment 2 is not limited to being provided on the front wall 11F of the base 11. For example, the carriage detection unit 66 is provided on the inner wall 11W of the base 11, It is also possible to detect the feeder carriage 21 positioned at the reference position by detecting the side surface of the feeder carriage 21 facing the wall 11W.
