By the operation of the unit 82 and the parts transfer device 86, the parts are supplied while being placed on the parts receiving member 392 of the parts carrier 388. FIG. Specifically, the worker puts the lead component 410 through the inlet 97 on the upper surface of the component feeder 88 . At this time, the component support member 150 has been moved below the component feeder 88 by the operation of the component support member moving device 152, and is in the retracted state (see FIG. 6). Note that when the component support member 150 is in the retracted state, the component collection container 180 disposed at the front end of the component support member 150 is positioned in front of the component supply device 88 so that the components can be collected. The opening of the recovery container 180 is in a posture (recovery posture) directed upward.

The lead component 410 input from the input port 97 of the component feeder 88 drops onto the inclined plate 104 of the component feeder 88 and rolls down to the front lower end of the inclined plate 104 . At this time, the lead components 410 that have rolled down to the front lower end of the inclined plate 104 are piled up between the front lower end of the inclined plate 104 and the rear lower end of the conveyor device 106 .

Since the method of classifying the components to be picked up and the components not to be picked up is not related to the present invention, it will be briefly described. The lead components 410 that are in contact with the upper surface of the component support member 150 and are inclined are classified as non-pickup target components, and the other lead components 410 are classified as pickup target components. Information such as the position on the component support member 150 and the attitude of the lead component 410 is acquired based on the imaging data for the lead component 410 classified as the pickup target component.

Then, based on the acquired position information of the pickup target component, the component holding head 302 is moved above the pickup target component by the operation of the component holding head moving device 300, and the pickup target component is sucked by the suction nozzle 332. retained. When the pick-up target component is sucked and held by the suction nozzle 332, the suction nozzle 332 is positioned at the non-turning position.

Next, after lead component 410 is held by suction nozzle 332 , component holding head 302 is moved above component carrier 388 . At this time, the component carrier 388 is moved to the component receiving position by the operation of the component carrier moving device 390 . Also, when the component holding head 302 moves above the component carrier 388, the suction nozzle 332 is swiveled to the swivel position. The suction nozzle 332 is rotated by the operation of the nozzle rotation 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.

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

When the lead component 410 is placed on the component receiving member 392, the component carrier 388 is moved to the component supply position by the operation of the component carrier moving device 390. FIG. Since the component carrier 388 that has moved to the component supply position is positioned within the movement range of the working heads 60 and 62, the bulk component supply device 32 supplies lead components 410 at this position. In this manner, the bulk component supply device 32 supplies the lead component 410 with the lead 414 facing downward and the top facing the bottom surface to which the lead 414 is connected facing upward. Therefore, the suction nozzles 66 of the working heads 60 and 62 can appropriately hold the lead component 410 .

(b) Collecting and Replenishing Lead Components In the bulk component supply device 32, when components to be picked up are scattered on the stage 156 of the component support member 150, the scattered components to be picked up are repeatedly picked up. The 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 to which the component receiving member 392 is mounted to the component supply position. However, when the pick-up target components are not scattered on the stage 156 of the component support member 150, that is, all the lead components 410 that can be picked up are picked up, and only the non-pick-up target components remain on the stage 156. In this case, lead component 410 cannot be picked up from stage 156 .

Therefore, in such a case, the bulk component supply device 32 collects the lead components 410 remaining on the stage 156 into the component collection container 180 . Then, the lead components 410 collected in the component collection container 180 are scattered again on the stage 156, and the orientation of the lead components 410 is changed, thereby restarting the pickup of the lead components 410 from the stage 156. be.

Specifically, the component support member 150 is moved downward from 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 collection container 180 disposed at the front end of the component support member 150 is in a posture with the opening facing upward, that is, in a recovery 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 feeder 88 . Furthermore, when the component support member 150 is moved to the stored state as shown in FIG.

Subsequently, the component support member 150 is moved forward from the stored state by the operation of the component support member moving device 152 . At the timing when the component support member 150 moves forward by a predetermined amount from the stored state, the container swinging device 181 of the component returning device 92 is actuated to swing the component collection container 180 . As a result, the posture of the component collection container 180 changes vigorously from the posture in which the opening faces upward (recovery posture) to the posture in which the opening faces the stage 156 (return posture). At this time, the lead components 410 collected in the component collection container 180 are vigorously ejected toward the stage 156 . As a result, the lead components 410 are scattered from the component collection container 180 onto the stage 156 , the attitude of the lead components 410 is changed, and the lead components 410 are picked up again from the stage 156 .

<Change in the type of parts supplied by the bulk parts supply device>
As described above, in the bulk component supply device 32 , the lead component 410 contained in the component supplier 88 is supplied while being placed on the component receiving member 392 of the component carrier 388 . Also, by exchanging the type of lead component 410 accommodated in the component supply device 88, the type of component supplied by the bulk component supply device 32 is changed. That is, the operator opens the safety door 136, takes out the component feeder 88 from the interior of the bulk component feeder 32, and replaces the lead component 410 housed inside the component feeder 88 with another type of component. replace. By attaching a component supply device 88 containing different types of components to the bulk component supply device 32, the type of components supplied by the bulk component supply device 32 can be changed.

However, in the bulk component supply device 32, the lead component 410 accommodated in the component supplier 88 is supplied while being placed on the component receiving member 392 of the component carrier 388. When the type of component to be supplied is changed, the type of lead component 410 accommodated in the component feeder 88 is changed, and the component receiving member 392 mounted on the component carrier 388 is also changed.

Specifically, as described above, the component receiving recess 416 having a shape corresponding to the component to be placed is formed in the component receiving member 392, and the supply component is placed in the component receiving recess 416. . Therefore, as shown in FIGS. 12 to 14, a plurality of types of component receiving members 392a to 392c are prepared according to the types of components supplied by the bulk component supply device 32. FIG.

Each of the component receiving members 392a to 392c is composed of a thick plate portion 470 and a thin plate portion 472, and the thick plate portion 470 and the thin plate portion 472 are integrally formed. A component receiving recess 416 having a shape corresponding to the component to be placed is formed in the substantially central portion of the upper surface of the plate thickness portion 470 . The component receiving member 392a is for placing the A component, and the component receiving recess 416 of the component receiving member 392a has a shape corresponding to the A component. The component receiving member 392b is for placing the B component, and the component receiving recess 416 of the component receiving member 392b has a shape corresponding to the B component. The component receiving member 392c is for placing the C component, and the component receiving concave portion 416 of the component receiving member 392c has a shape corresponding to the C component.

Further, an identification plate 478 is attached to a corner portion of the upper surface of the plate thickness portion 470 . A 2D code (not shown) is written on the identification plate 478 , and the 2D code corresponds to the type of component placed in the component receiving recess 416 . Therefore, the identification plate 478 of the component receiving member 392a is marked with a 2D code corresponding to the A component, and the identification plate 478 of the component receiving member 392b is marked with a 2D code corresponding to the B component. A 2D code corresponding to the C component is written on the identification plate 478 of the component receiving member 392c.

A pair of through holes 480 and 482 are formed through the thin plate portion 472 of each of the component receiving members 392a to 392c in the vertical direction. The pair of through holes 480, 482 are formed at the same positions in each of the component receiving members 392a to 392c, and a pair of pins (not shown) that can be inserted into the pair of through holes 480, 482. are arranged on the component carrier 388 . Therefore, by inserting the pins of the component carrier 388 into the through holes 480 and 482 of the component receiving members 392a to 392c, the component carrier 388 is moved while the component receiving members 392a to 392c are positioned at predetermined positions. is attached to the

With such a structure, when the type of parts supplied by the bulk parts supply device 32 is changed, the operator can lift up the parts receiving members 392a to 392c mounted on the parts carrier 388. , the pins are removed from the through holes 480, 482, and the component receiving members 392a-c mounted on the component carrier 388 are removed. Further, among the plurality of component receiving members 392a to 392c, the component receiving members 392a to 392c corresponding to the components to be supplied by the bulk component supply device 32, that is, the component receiving members 392a to 392c corresponding to the components accommodated in the component supply device 88 Members 392a-c are selected. By lowering the selected component receiving members 392a to 392c above the component carrier 388, the operator inserts the pins of the component carrier 388 into the through holes 480 and 482 of the component receiving members 392a to 392c. do. As a result, the selected component receiving members 392a-c are mounted on the component carrier 388 while being positioned at predetermined positions.

In this way, the parts accommodated in the parts feeder 88 are replaced with the parts to be supplied, and the part receiving members 392a to 392c attached to the parts carrier 388 are replaced with those corresponding to the parts to be supplied. , the type of parts supplied by the bulk parts supply device 32 can be changed. However, the operator may forget to replace the component receiving members 392a to 392c even after replacing the component contained in the component feeder 88. FIG. In addition, although the operator has to replace the component receiving members 392a to 392c attached to the component carrier 388 with those corresponding to the components to be supplied, the operator mistakenly replaces the components different from the components to be supplied. It may be exchanged for a suitable one. In this manner, when the component receiving members 392a to 392c corresponding to the components to be supplied are not mounted on the component carrier 388 due to human error, the components can be properly placed on the component receiving members 392a to 392c. not be able to supply adequate parts.

Specifically, for example, the operator may mistakenly mount the component receiving member 392c on the component carrier 388 even though the component to be supplied is the A component. Since the component receiving recess 416 of the component receiving member 392a corresponding to the A component is relatively large as shown in FIG. 12, it can be understood that the A component is a relatively large component. On the other hand, the component receiving recess 416 of the component receiving member 392c is relatively small as shown in FIG. Therefore, when the component receiving member 392c is attached to the component carrier 388 even though the component to be supplied is the A component, the A component cannot be placed in the component receiving recess 416 of the component receiving member 392c. cannot supply the A parts.

In view of this, in the bulk component supply device 32, the identification plates 478 of the component receiving members 392a to 392c mounted on the component carrier 388 are imaged by the camera 290 of the imaging device 84, and based on the imaged data. , whether or not the component receiving members 392a-c mounted on the component carrier 388 correspond to the components to be supplied. Specifically, camera 290 is moved above component carrier 388 by actuation of camera mover 292 . Then, the identification plate 478 of the component receiving members 392a to 392c attached to the component carrier 388 is imaged by the camera 290, and the imaging data of the identification plate 478 obtained by the imaging is transmitted to the individual control device 452. . The individual control device 452 analyzes the transmitted imaging data and identifies the 2D code written on the identification plate 478 .

The storage device 456 also stores, for each of the plurality of component receiving members 392a to 392c, a 2D code written on the identification plate 478 of each of the component receiving members 392a to 392c, and a component receiving concave portion of each of the component receiving members 392a to 392c. 416 stores the types of parts that can be placed in association with each other. For this reason, the individual control device 452 refers to the information stored in the storage device 456 and determines the type of component associated with the 2D code specified based on the imaging data (hereinafter referred to as "2D code compatible component type"). (sometimes described as

The storage device 456 also stores a program for executing parts supply work by the bulk parts supply device 32 . In this program, the types of parts to be supplied, the number of parts to be supplied, supply timing, etc. are programmed. For this reason, the individual control device 452 determines the type of parts scheduled to be supplied by the bulk parts supply device 32 (hereinafter sometimes referred to as "parts scheduled to be supplied") based on the program stored in the storage device 456. identify. Then, the individual control device 452 determines whether or not the 2D code compatible component type and the supply scheduled component type are the same. At this time, if the 2D code compatible component type and the scheduled supply component type are the same, the bulk component supply device 32 performs the component supply operation. On the other hand, when the 2D code compatible component type and the scheduled supply component type are different, the loose component supply device 32 does not perform the component supply operation, and the display device (not shown) displays the 2D code compatible component type and the scheduled supply component type. A screen indicating that the part type is different is displayed. As a result, the operator recognizes that the component receiving members 392a to 392c corresponding to the components different from the components to be supplied are mounted on the component carrier 388, and the component receiving members 392a to 392c mounted on the component carrier 388 c is replaced with one corresponding to the part to be supplied.

The confirmation work of the component receiving members 392a to 392c based on the imaging data of the identification plate 478 is performed each time the safety door 136 of the bulk component supply device 32 is opened and closed. This is because when the safety door 136 is opened and closed, there is a possibility that the parts contained in the parts feeder 88 and the parts receiving members 392a to 392c mounted on the parts carrier 388 are being replaced. This is because the

In this way, the individual control device 452 automatically determines whether the 2D code compatible component type and the scheduled supply component type are the same, and if the 2D code compatible component type and the scheduled supply component type are different, By displaying a screen indicating this, it is possible to prevent the occurrence of human errors such as incorrect mounting of the component receiving members 392a to 392c. As a result, the component receiving members 392a to 392c corresponding to the components to be supplied can be reliably attached to the component carrier 388, and appropriate component supply by the bulk component supply device 32 can be ensured.

11, the individual control device 452 has an identification unit 500, an acquisition unit 502, and a determination unit 504. As shown in FIG. The specifying unit 500 is a functional unit for specifying a 2D code compatible component type. The acquisition unit 502 is a functional unit for acquiring the supply-scheduled part type.
