  When the lead component 410 discharged from the component feeder 88 onto the stage 156 rolls forward and falls from the front end of the stage 156, it is stored in the component storage container 180. When the lead component 410 discharged from the component feeder 88 onto the stage 156 rolls sideways, the lead component 410 is dropped from the stage 156 by the side wall portion 158 of the component support member 150. Is prevented.

  Then, when the component support member 150 is moved forward from the retracted state and reaches the exposed state, the movement of the component support member 150 is stopped. As a result, the lead components 410 are scattered over the entire upper surface of the stage 156. In the component supplier 88, the operation of the conveyor device 106 is stopped so that the lead component 410 is finally discharged from the component supplier 88 in synchronization with the timing at which the movement of the component support member 150 is stopped.

  When the lead component 410 is scattered on the stage 156 of the component support member 150 from the component supplier 88 in accordance with the above-described procedure, the camera 290 of the imaging device 84 is operated by the camera moving device 292 to operate the component support member 150. The lead component 410 is imaged by being moved upward. A plurality of lead components 410 scattered on the upper surface of the component support member 150 can be picked up by the suction nozzle 332 based on the imaging data (hereinafter, referred to as “pickup target component” in some cases). The lead nozzle 332 separates the lead parts that cannot be picked up (hereinafter may be referred to as “non-pickup target parts”). The method of distinguishing between the pickup target component and the non-pickup target component is not related to the present invention, and will be described briefly. However, the lead component 410 and the lead 414 in a state where the surface that is difficult to attract, such as the uneven surface, faces upward. The lead component 410 and the like that are in contact with the upper surface of the component support member 150 and are tilted are classified as non-pickup target components, and the other lead components 410 are classified as pickup target components. Further, information such as the position on the component support member 150 and the posture of the lead component 410 is acquired for the lead component 410 classified as the pickup target component based on the imaging data.

  The component holding head 302 is moved above the pickup target component by the operation of the component holding head moving device 300 based on the acquired position information of the pickup target component, and the pickup target component is sucked by the suction nozzle 332. Retained. Note that when the pickup target component is sucked and held by the suction nozzle 332, the suction nozzle 332 is located at the non-turning position.

  Next, after the lead component 410 is held by the suction nozzle 332, the component holding head 302 is moved above the component carrier 388. At this time, the component carrier 388 moves to the component receiving position by the operation of the component carrier moving device 390. Further, when the component holding head 302 moves above the component carrier 388, the suction nozzle 332 is pivoted to the pivot position. The suction nozzle 332 is rotated by the operation of the nozzle rotating device 335 so that the lead 414 of the lead component 410 held by the suction nozzle 332 in the turning position faces downward in the vertical direction.

  When the component holding head 302 moves above the component carrier 388, the lead component 410 with the lead 414 facing downward in the vertical direction is inserted into the component receiving recess 416 of the component receiving member 392. As a result, as shown in FIG. 10, the lead component 410 is placed on the component receiving member 392 with the lead 414 facing downward in the vertical direction.

  When the lead component 410 is placed on the component receiving member 392, the component carrier 388 moves to the component supply position by the operation of the component carrier moving device 390. Since the component carrier 388 moved to the component supply position is located in the movement range of the work heads 60 and 62, the lead component 410 is supplied at this position in the loose component supply device 32. As described above, in the bulk component supply device 32, the lead component 410 is supplied in a state where the lead 414 faces downward and the upper surface facing the bottom surface to which the lead 414 is connected faces upward. For this reason, the suction nozzle 66 of the work heads 60 and 62 can hold the lead component 410 appropriately.

(B) Accommodating lead components in a component container and scattered on the stage In the bulk component supply device 32, when the pickup target components are scattered on the stage 156 of the component support member 150, the lead components are scattered. Pickup of the picked up target component is repeated, and the picked up picked up target component is placed on the component receiving member 392. Then, the lead component 410 is supplied by moving the component carrier 388 on which the component receiving member 392 is mounted to the component supply position. However, when the pickup target parts are not scattered on the stage 156 of the part support member 150, that is, all the lead parts 410 that can be picked up are picked up, and only the non-pickup target parts remain on the stage 156. In this case, the lead component 410 cannot be picked up from the stage 156.

  For this reason, in such a case, the lead component 410 remaining on the stage 156 is temporarily stored in the component storage container 180 in the bulk component supply device 32. Then, the lead components 410 accommodated in the component container 180 are scattered again on the stage 156, and the posture of the lead components 410 is changed, so that the pickup of the lead components 410 from the stage 156 is resumed. The

  Specifically, the component support member 150 is moved downward of the component feeder 88 by the operation of the component support member moving device 152. That is, the component support member 150 is moved from the exposed state (see FIG. 5) toward the retracted state (see FIG. 6). At this time, the component storage container 180 disposed at the front end of the component support member 150 is in a posture in which the opening is directed upward, that is, in a storage posture. As the component support member 150 moves, the lead component 410 on the stage 156 of the component support member 150 is blocked by the front end of the inclined plate 128 of the component supplier 88. Further, as shown in FIG. 6, when the component support member 150 is moved to the retracted state, the lead component 410 on the stage 156 is scraped off into the component storage container 180.

  Subsequently, the component support member 150 is moved forward from the retracted state by the operation of the component support member moving device 152. Then, at the timing when the component support member 150 moves forward by a predetermined amount from the retracted state, the container swinging device 181 of the component returning device 92 operates, and the component receiving container 180 swings. As a result, the posture of the component storage container 180 changes rapidly from a posture with the opening facing upward (accommodating posture) to a posture with the opening facing the stage 156 (returning posture). At this time, the lead component 410 accommodated in the component accommodating container 180 is released toward the stage 156 vigorously. As a result, the lead components 410 are scattered from the component container 180 onto the stage 156, whereby the posture of the lead components 410 is changed, and the lead components 410 are picked up again from above the stage 156.

<Changing the type of parts supplied by the bulk parts supplier>
As described above, in the bulk component supply device 32, the lead component 410 accommodated in the component supplier 88 is supplied in a state of being placed on the component receiving member 392 of the component carrier 388. In addition, by replacing the type of the lead component 410 accommodated in the component supplier 88, the type of component supplied by the bulk component supply device 32 is changed. That is, the operator takes out the component supplier 88 from the inside of the bulk component supplier 32 and replaces the lead component 410 accommodated in the component supplier 88 with another type of component. And the kind of components supplied by the bulk component supply device 32 can be changed by mounting the component feeder 88 containing different types of components on the bulk component supply device 32.

  However, when the type of the component supplied by the bulk component supply device 32 is changed, the component may remain on the stage 156 of the component support member 150. It is necessary to collect the remaining parts. For this reason, in the conventional method, the operator manually collects the parts remaining on the stage 156 by hand. Alternatively, as described above, by moving the component support member 150 from the exposed state (see FIG. 5) to the stored state (see FIG. 6), the components remaining on the stage 156 can be moved into the component storage container 180. The components were housed and the components housed in the components storage container 180 were manually collected by the operator. However, when many parts remain on the stage 156, it is necessary for the operator to collect the parts from the stage 156 or the component storage container 180 a plurality of times. Also gets longer. Further, at the time of parts collection, an operator puts his hand inside the bulk parts supply device 32 to perform the parts collection work. However, since the inside of the bulk parts supply apparatus 32 is narrow, it is difficult to perform the collection work.

  In view of such a situation, in the bulk component supply device 32, the components remaining on the stage 156 are temporarily stored in the component storage container 180, and the components stored in the component storage container 180 are collected. By referring to FIG. 12), the parts remaining on the stage 156 are collected and collected at a time. Specifically, the plurality of operation switches 458 described above have a collection start switch, and when the collection start switch is operated, an operation signal is input to the individual control device 452. When the individual control device 452 receives the operation signal, the individual control device 452 operates the component support member moving device 152 so as to move the component support member 150 from the exposed state (see FIG. 5) to the retracted state (see FIG. 6). Control. At this time, the component storage container 180 is in the storage posture. As the component support member 150 moves, the lead component 410 on the stage 156 of the component support member 150 is accommodated in the component storage container 180 as described above. Next, when the component support member 150 reaches the retracted state, the individual controller 452 moves the component support member so as to move the component support member 150 from the retracted state (see FIG. 5) to the exposed state (see FIG. 6). The operation of the device 152 is controlled.

  When the component support member 150 reaches the exposed state, the individual control device 452 displays a screen prompting the user to set the collection container 470 on the upper surface of the stage 156 of the component support member 150 on the display device 456. As shown in FIG. 12, the collection container 470 has a generally rectangular parallelepiped box shape. The lower surface 472 of the recovery container 470 has a rectangular shape, the long side is substantially the same as the length in the front-rear direction of the stage 156, that is, the Y direction, and the short side is slightly longer than the width direction of the stage 156, that is, the length in the X direction It has been shortened. The dimension of the stage 156 is the dimension of the stage 156 in the exposed state (see FIG. 5). A pair of side surfaces 474 are erected on a pair of long sides of the lower surface 472 of the collection container 470, and a side surface 476 is erected on one short side of the pair of short sides of the lower surface 472. ing. In addition, a notch portion 478 that is notched in a stepped shape is formed on the upper portion on one end side in the longitudinal direction of each of the pair of side surfaces 474. Further, the upper surface 480 of the recovery container 470 has a rectangular shape with a shorter side than the lower surface 472 and covers the upper end of the recovery container 470 excluding the notch 478. That is, the collection container 470 has a generally rectangular parallelepiped box shape, and the side surface on one end side in the longitudinal direction is open. A generally rectangular through hole 482 is formed at the end of the upper surface 480 of the collection container 470 on the side close to the notch 478.

  Then, when a screen prompting the user to set the collection container 470 on the upper surface of the stage 156 is displayed on the display device 456, the notch 478 of the collection container 470 is displayed on the component storage container 180 as shown in FIG. The collection container 470 is placed on the upper surface of the stage 156 so as to face. That is, the collection container 470 is placed on the upper surface of the stage 156 so that the opening of the collection container 470 faces the component storage container 180. At this time, the end surface on the opposite side of the cutout portion 478 of the recovery container 470 is in contact with the inclined plate 128 of the component feeder 88, and the end portion on the cutout portion 478 side of the recovery container 470 is the component storage container of the stage 156. It substantially coincides with the end portion on the 180 side.

  The plurality of operation switches 458 include a placement completion switch. When the worker completes the placement of the collection container 470 on the stage 156, the operator operates the placement completion switch. When the placement completion switch is operated, an operation signal is input to the individual control device 452. When receiving the operation signal, the individual control device 452 changes the component container 180 from a posture with the opening facing upward (accommodating posture) to a posture with the opening facing the stage 156 (return posture). The operation of the container peristaltic device 181 is controlled. At this time, as shown in FIG. 14, the lead component 410 accommodated in the component accommodating container 180 is discharged toward the opening of the recovery container 470 placed on the stage 156. As a result, the lead component 410 accommodated in the component accommodating container 180 is recovered inside the recovery container 470. Note that when the parts container 180 is swung in a posture in which the opening is directed toward the stage 156 (returning posture), the contact between the collecting container 470 and the parts container 180 is avoided by the notch 478 of the collecting container 470. Is done.

  Subsequently, when the operation of the component container 180 is completed, the individual control device 452 turns on a collection work end lamp (not shown). When the operator confirms that the collection operation end lamp is lit, the operator pierces his / her hand into the bulk component supply device 32, inserts a finger into the through hole 482 of the collection container 470, and holds the collection container 470. Then, by taking out the collection container 470 to the outside of the bulk component supply device 32, all the components remaining on the stage 156 are taken out to the outside of the bulk component supply device 32 and collected. As described above, in the bulk component supply device 32, the operator sets the collection container 470 on the stage 156, performs a switch operation, and then simply removes the collection container 470 and remains on the stage 156. All parts can be collected. As a result, the burden on the operator can be reduced, and the time required for the parts collection operation can be shortened.

  In addition, after the operator sets the collection container 470 on the stage 156, the component support member moving device 152 may be operated by forgetting that the collection container 470 has been set on the stage 156. In such a case, the stage 156 slides slightly, and the collection container 470 set on the stage 156 comes into contact with the component storage container 180, whereby the sliding of the component support member 150 is restricted. Specifically, when the collection container 470 is set on the stage 156, the end surface on the opposite side of the notch 478 of the collection container 470 is in contact with the inclined plate 128 of the component supplier 88, and the notch of the collection container 470 The end portion on the 478 side substantially coincides with the end portion on the component storage container 180 side of the stage 156. Further, as shown in FIG. 13, a protruding surface 490 that protrudes upward is disposed at the end of the component container 180 opposite to the center of peristaltic movement. The projecting surface 490 is provided to vigorously release the components housed inside when the component housing container 180 is swung. When the component support member 150 is slid from the exposed state to the retracted state with the recovery container 470 set on the stage 156, the end surface on the opposite side of the cutout portion 478 of the recovery container 470 is the inclined plate of the component supplier 88. In a state where it is in contact with 128, the end of the collection container 470 on the side of the notch 478 abuts on the protruding surface 490 of the component container 180. Thus, even when the recovery container 470 is forgotten to be set on the stage 156 and the component support member moving device 152 is operated, the sliding of the component support member 150 can be restricted.

  Further, as illustrated in FIG. 11, the individual control device 452 includes a reception unit 500, a storage unit 502, a notification unit 504, an acquisition unit 506, and a collection unit 508. The accepting unit 500 is a functional unit for accepting a switch operation of the collection start switch. The accommodating portion 502 is a functional portion for operating the component supporting member moving device 152 and accommodating the components remaining on the stage 156 in the component accommodating container 180.

The acquisition unit 506 is a functional unit for acquiring that the collection container 470 is set on the stage 156 by the switch operation of the placement completion switch. The collection unit 508 operates the container peristaltic device 181 to change the component storage container 180 from a posture with the opening facing upward (accommodating posture) to a posture with the opening facing the stage 156 (returning posture). It is a functional part.
