As a result, the positioning pins 320 and 322 are detached from the positioning holes 360 and 362, the recesses 268 are detached from the rotating disk 340, and the leading path is maintained with the entire bulk component driving device 338 held by the mounting head 25. The accessory case 252 is removed from the mounting head 25. The bulk component rolling device 392 constituted by the guide groove 266 and the scraping-off portion 283 is in the part passage-provided case 252 and is removed from the mounting head 25 together with the part passage-provided case 252.

  After removing the part case 252 with the front passage, the mounting head 25 is moved to a case delivery position set in advance with respect to a case holding part for holding the part case 252 with the rear passage, here the case holding part 452. After the movement, as shown in FIG. 14 (c), the elevating member 460 is raised to the raised end position, and the case holding portion 452 holding the part case 252 with the rear passage is raised to the case delivery position. As a result, the turntable 340 is fitted into the recess 268 of the component case 252 with the rear passage, the positioning pins 320 and 322 are fitted into the positioning holes 360 and 362, and the periphery of the positioning pins 320 and 322 of the passage forming body 310. The portion is brought into contact with the lower surface of the head main body 180. After the case holding portion 452 is lifted, the clamp claw 376 is rotated to the clamp position, and the component case 252 with the rear passage is held by the mounting head 25 in a state where it is positioned in the horizontal direction and the vertical direction, and the bulk component is driven. By the device 338, a moving force in a direction toward the component passage 258 can be applied to the component 294 in the storage chamber 272.

  After the part case 252 with the rear passage is held by the mounting head 25 and becomes the part case 252 with the front passage, the case holding portion 452 holding the part case 252 with the passage is lowered to the retracted position, The case holding portion 452 is obtained. Then, the mounting head 25 resumes mounting of the circuit board 40 of the component 294 supplied from the new component case 252 with a leading path.

  On the other hand, in the replacement unit 400, the slide 404 is moved to the retracted end position and is positioned in the bulk parts supply area. The display screen 534 displays that the part case 252 with the front passage is emptied and the type of the part 294 supplied by the part case 252 with the front passage. The part 294 is put into the storage chamber 272 of the part case 252 with the front passage and becomes a part case 252 with the rear passage. Since the bulk parts supply area is outside the head movement area and outside the module main body 18, the operator can work in parallel with the parts mounting work by the mounting head 25 in a wide place. Next, when the part case 252 with the front passage and the part case 252 with the rear passage are exchanged, the empty case holder 452 receives the part case 252 with the front passage, and the case holder 450 receives the part case 252 with the rear passage. To the mounting head 25. The case holding portions 450 and 452 alternately become a component case holding portion with a front passage and a component case holding portion with a rear passage.

  The worker can also replace the part case 252 with passage held in one of the case holding portions 450 and 452 with a spare part case 252 with passage. The spare part case with a passage 252 is a part case with a passage 252 that is different from the two part cases with a passage 252 that are actually used for supplying the parts. For example, in the place different from the mounting module 10, It may be a part case 252 with a passage in which the same kind of part as the part currently supplied is accommodated, or a part case with a passage in which a part of a type different from the two part cases 252 with a passage is accommodated. It may be. By replacement, for example, in the former case, replacement of the part case 252 with the previous passage, which has become impossible to supply parts due to parts replenishment or abnormality, is performed with the part case 252 with the normal passage. In the latter case, the supply parts Changes are made. The bulk parts supply area is also a part case work area.

When the part case 252 with the front passage and the part case 252 with the rear passage are replaced, information is exchanged among the module control computer 122, the mounting head control computer 232, and the replacement unit control computer 520, and the case holding portions 450 and 452 Control is performed so that the rise or the like is performed at a predetermined timing. This exchange of information can be performed in various ways, an example of which is as follows.
First, in the module control computer 122, on the basis of a program corresponding to the type of electronic circuit to be assembled, the types of electronic circuit components to be supplied from the component supply devices 23 and 24, and tapes for supplying these electronic circuit components The mounted portion 54 on the component supply base 52 of the feeder 50 and the replacement unit 400 is determined and displayed on the display screen 534.

  According to the display, the worker attaches the tape feeder 50 to each of the plurality of attachment portions 54 of the component supply base 52 and attaches the replacement unit 400. The tape feeder 50 and the exchange unit 400 are respectively provided with a tape feeder control computer 120 and an exchange unit control computer 520, and a connector 118 and a connector 422. When the tape feeder 50 and the exchange unit 400 are attached to the component supply base 52, the connectors 118 and 422 supply the components. The position of the connector 64 is specified by the module control computer 122 and the information is sent to the module control computer 122 via the connector 64. From the tape feeder control computer 120, the type of the tape feeder information and the taped component 78 that can identify the tape feeder 50 individually, and from the replacement unit control computer 520, the unit information and the case that can identify the replacement unit 400 individually. The types of components 294 supplied by the component case with passage 252 held by the holding portions 450 and 452 are respectively sent. Before the tape feeder 50 is attached to the component supply base 52, the taped component 78 is set. At this time, the electronic circuit component of the taped component 78 from the information recording unit attached to the component holding tape 76 is set. Are read by the information reading device and stored in the memory of the tape feeder control computer 120. This information is sent together with the tape feeder information.

  Regarding the exchange unit 400, an RFID reader / writer 560 (see FIG. 15) is provided in the exchange device main body 402, and a separate antenna 562 is provided on the slide 404 corresponding to each of the case holding portions 450 and 452. (See FIG. 12). The antenna 562 is connected to the main body of the RFID reader / writer 560 by a cord, and the RFID reader / writer 560 is connected to the exchange unit control computer 520. As a result, the component type information stored in the storage unit of the RF tag 330 in a state where the component case with a passage 252 is held by the case holding units 450 and 452 is transmitted by the RFID reader / writer 560 via the antenna 562. It is read and stored in the memory of the exchange unit control computer 520. This information is sent along with the unit information.

  Based on the information sent in this way and the information on the position of the attached portion 54 to which the tape feeder 50 and the replacement unit 400 are attached, the tape feeder 50 and the replacement unit 400 are respectively scheduled from the intended attached portion 54. It is determined whether or not a scheduled type of electronic circuit component is supplied. If the result of the determination is that either the position of the mounted portion 54 or the type of the electronic circuit component is not as planned, a display is displayed. A message to that effect is displayed on the screen 534. At the same time, when the tape feeder 50 is not as scheduled, the mounting module 10 is in a component mounting operation prohibited state. When the replacement unit 400 is not as scheduled, the mounting head 25 and the replacement unit 400 are in the component case 252 with a passage. The replacement operation is disabled. When the type of parts supplied by the part case 252 with passage held by the replacement unit 400 is different from the planned type, this is known before the part case 252 with path is attached to the mounting head 25, and the mounting head 25 and the exchange unit 400 are prevented from performing the delivery operation of the part case 252 with a passage whose part type is different from the planned type. In response to the display, the position of the mounted portion 54 or the part case 252 with a passage or the tape feeder 50 is changed, and if the error is corrected, the component mounting operation prohibition state or the replacement operation prohibition state is canceled.

  Further, as described above, when the component case 252 with passage is attached to the mounting head 25 by the replacement unit 400, the component case 252 with passage is stored in the storage unit of the RF tag 330 of the component case 252 with passage. The stored component type information is read by the RFID reader / writer 388 via the antenna 390, and based on the read information, it is determined whether or not the scheduled type of component 294 is supplied. It is reconfirmed whether the type of the parts 294 supplied by the part case 252 with a passage attached to is as planned. As a result of the determination, if the type of the component 294 is not as planned, a message to that effect is displayed on the display screen 534 and the mounting module 10 is in a component mounting operation prohibited state. If the passage case 252 is changed according to the display and the error is corrected, the operation prohibition state is released.

  The confirmation of the type of the component 294 in the component case 252 with a passage attached to the mounting head 25 is particularly effective when the component case is attached to and detached from the mounting head manually.

  Further, the connection of the connectors 118 and 422 to the connector 64 and the feeding of feeder information, taped component type information, unit information, and accommodated component type information in the module control computer 122 cause the tape feeder 50 and the component supply base 52 of the replacement unit 400 to be sent. The tape feeder 50 and the replacement unit 400 are attached to any one of the plurality of attached portions 54 of the component supply base 52 by specifying the mounting position in the printer and acquiring the type of component to be supplied. The mounting head 25 can be moved to the tape feeder 50 based on the specification of the position and the supply component type, and the electronic circuit component can be taken out, or can be moved to the replacement unit 400 to replace the part case with a passage. .

  A plurality of replacement units 400 may be attached to the component supply base 52. In that case, the types of components supplied by the component case 252 with a passage to be replaced in each of the plurality of replacement units 400 may be the same or different.

The tape feeder information and unit information that can individually identify the tape feeder 50 and the replacement unit 400 are used to specify the tape feeder 50 and the replacement unit 400 in the module control computer 122 and perform control related thereto. Used. For example, it is used for managing the remaining parts of the taped parts 78 and the parts case 252 with passage and the information management of their malfunctions.
In the present embodiment, when the part 294 is put into the part case 252 with a passage, information about the part 294 such as the type, specification, number of chip parts provided in the package of the part 294 is held. The two-dimensional code 334 provided in the component case 252 with the passage is read together with the two-dimensional code being stored, and stored in the storage unit of the RF tag 330.
However, this is not essential. When the part 294 accommodated in the part case 252 with a passage is determined as one type, information on the one type of chip part may be stored in the storage unit of the RF tag 330 in advance.

  In addition, the tip part case holding part and the rear part case holding part of the movable member may be provided side by side in a direction intersecting the moving direction of the movable member.

  A plurality of different types of component cases may be set in one replacement unit. For example, a plurality of sets of movable members, movable member driving devices, and bulk component case replacement devices are supported on one replacement device body, and the types of components supplied by the component cases to be replaced in each set are made different.

Or you may hold | maintain two component cases from which the kind of bulk component to supply differs in the two case holding parts of the movable member of an exchange unit. For example, when two types of bulk components are mounted on a single circuit board, two component cases that accommodate each of the two types of bulk components are held by two case holding portions and mounted on the circuit board. Every time the type of the bulk part changes, the part case is exchanged between the mounting head and the exchange unit. Alternatively, when the type of the circuit board changes and the type of the bulk component to be mounted changes, it is a component case that is held by one of the two case holders, and is a bulk that is mounted on the circuit board before the type change The operator replaces the component case that supplies the component with a component case that contains different types of bulk components to be mounted on the circuit board after the type change, and the component case that is actually held by the mounting head is If the part case is replaced with a part case to be used and held in the case holding part, the part case is also replaced with a part case to be used next. In this case, in the process of changing the two component cases accompanying the change in the type of the circuit board, two component cases having different types of bulk components to be supplied are held in the mounting head and the replacement unit.
Note that the number of case holding portions of the movable member is not limited to two, and may be three or more, and the types of bulk parts supplied by the component cases held by the plurality of case holding portions may be the same or different. Also good.

In the above embodiment, the replacement of the front part case and the rear part case is automatically performed by the bulk part case replacement unit, but this is not indispensable. For example, a collection unit that collects the front part case is provided inside the head movement area, the mounting head is moved to the collection unit, the front part case is discharged, and the rear part case is held by the mounting head by the operator. Alternatively, a rear bulk part case holding device may be provided inside the head moving area so that the rear part case is delivered to the mounting head. The tip part case may be removed from the mounting head by the operator.
The rear part case may be moved from the outside to the inside of the head moving area by a bulk part case moving device. If the rear bulk part case holding device is provided in the head moving area, the rear part case is carried to the holding apparatus, and if it is provided outside the head moving area, the rear bulk part case holding apparatus is The rear part case will be carried into the head moving area, and if the rear bulk part case holding device is not provided, the rear part case will be carried to a position held by the mounting head in the head moving area. .
When the discharge of the front part case by the mounting head and the holding of the rear part case are performed separately, the rear part case can be automatically mounted on the mounting head by the bulk part case mounting apparatus. The bulk component case mounting device is preferably a bulk component case replacement device that replaces the leading component case and the trailing component case, but is not essential. For example, when the front part case is discharged to the collecting unit as described above, it is not necessary to be a replacement device, and the front part case mounting device for mounting the front part case and the rear part case for removing the rear part case The removal device may be provided separately.
