In the circuit component supply system according to the present invention, by using a feeder identification code unique to the feeder, it is possible to specify which of the plurality of feeders is held by the feeder holding member of the feeder holding member. It was made as an issue.
Since the circuit component supply system according to this section includes the first communication network, information exchange is performed between the feeder-side controller provided in each feeder and the holding-member-side controller provided in the feeder holding member. Can do. If a feeder is held by the feeder holding member, the feeder controller of the feeder is connected in parallel to the holding member controller by the first communication network. That is, the signal on the first communication network can be simultaneously received by the holding member side controller and all the feeder side controllers connected thereto. Specifically, for example, the first communication network can have a simple configuration mainly composed of a pair of twisted pair wires terminated at both ends by resistors, a single coaxial cable, and the like. The configuration of the apparatus can be simplified. When a controller connected to such a communication network receives a signal, the signal on the communication network is disturbed due to the function of identifying the controller to which the signal is transmitted or the simultaneous transmission from a plurality of controllers. A communication system that realizes a function to prevent this is already known. Of these, CSMA / CD, token passing, polling, etc. are often used. In communication using such a communication network and communication system, each controller generally has unique address information. The feeder identification code can be used as the address information. However, the position of the feeder holding unit holding the target feeder cannot be specified only by communication using the first communication network. Therefore, the circuit component supply system is further configured to include the second communication network. The second communication network independently connects the feeder-side controllers of the feeders held in the feeder holding unit to the holding member-side controllers. That is, the holding member side controller can perform transmission / reception of a signal via the second communication network while always specifying the position of the feeder holding unit holding the feeder including each feeder side controller.
By performing communication using these first communication network and second communication network or exchanging signals, the specifying control means specifies the feeder holding unit holding the feeder holding the target feeder identification code. Can do. The procedure for that is not restricted to one, For example, the procedure shown below is employable.
Step 1:
(i) Each feeder transmits a feeder identification code on the first communication network. The holding member side controller receives this. (ii) The holding-member-side controller sends a command to the first communication network to send a signal on the second communication network with the received feeder identification code. All feeders receive this command from the first communication network. (iii) The feeder controller of each feeder compares the feeder identification code attached to the received command with its own feeder identification code, and if they match, sends a signal on the second communication network. (iv) The holding member side controller specifies the position of the feeder holding unit from which a signal is transmitted on the second communication network.
Step 2:
(i) Each feeder transmits a feeder identification code on the first communication network. The holding member side controller receives this. (ii) The holding member side controller transmits the following command on the first communication network. This command is sent to all the feeder-side controllers, and when the signal is received from the second communication network, the content is confirmed by adding its own feeder identification code to the information confirming reception. Send to one communication network. (iii) After that, the holding member side controller sequentially transmits a signal on the second communication network corresponding to each feeder holding unit, receives a signal on the first communication network in response thereto, the contents thereof, and each feeder holding Based on the position of the part, the position of the feeder holding part in which the feeder that first transmitted the feeder identification code is held on the first communication network is specified.
Step 3:
(i) The holding member side controller sequentially transmits feeder identification codes of feeders that may be held by the feeder holding member on the first communication network. All feeder-side controllers receive the feeder identification code. (ii) A feeder-side controller whose received feeder identification code matches its own feeder identification code transmits a signal on the second communication network. (iii) When the holding member-side controller receives a signal from the second communication network, the feeder holding the feeder identification code transmitted to the first communication network immediately before is based on the received signal from the second communication network. It is specified that it is held in the specified feeder holding unit.
Step 4:
(i) The holding member side controller sequentially transmits signals onto the second communication network corresponding to all the feeder holding units. (ii) When the feeder side controller of the feeder held in each feeder holding unit receives a signal from the second communication network, it transmits its own feeder identification code on the first communication network. (iii) When the feeder identification code is transmitted on the first communication network, the holding member-side controller sends a signal to the feeder holding unit corresponding to the second communication network immediately before the feeder holding the feeder identification code To be held. In addition, the procedure in which a specific control means specifies a feeder holding | maintenance part using a 1st communication network and a 2nd communication network is not necessarily restricted to the above four, There exist others. In the circuit component supply system of the present invention, any one of such procedures may be used.
As is apparent from the above description, the invention according to this section is based on the assumption that the first communication network for performing general information exchange is a normal communication network in which a plurality of feeder-side controllers are connected in parallel to the holding member-side controller. It is possible to identify where a plurality of feeders are held in a plurality of feeder holding portions of a feeder holding member by using a second communication network that performs simple communication and a feeder identification code. It is a thing.
Moreover, in the circuit component supply system of this invention, even if each feeder is hold | maintained at which feeder holding | maintenance part, the feeder holding | maintenance part which these feeders are hold | maintained can be specified. For this reason, if there is an error in the feeder mounting position by the worker, the error content can be displayed on the display device to notify the worker, thereby making it easy to correct the mounting error. Furthermore, if the circuit component supply program is created based on the feeder identification code, not based on the position of the feeder holding unit, even if there is an error in the feeder mounting position by the operator, it remains as it is. Parts supply work can be performed without any problem, and correction of the mounting position itself is not essential.
(26) a component / feeder storage means for storing a feeder identification code unique to each of the plurality of feeders and a component identification code unique to each type of circuit component housed in each of the feeders;
Based on the information stored in the component / feeder storage unit and the feeder identification code of the feeder held in the feeder holding unit specified by the specifying control unit, the circuit component corresponding to each feeder holding unit The circuit component supply system according to item (25), comprising circuit component determination means for determining a type.
In the circuit component supply system according to item (25), each of the plurality of types of circuit components is held in any of the plurality of component holding portions of the component holding member by using the feeder identification code. It has been made as an object to be able to specify whether the feed is supplied from a feeder.
In the circuit component supply system according to the present invention, the circuit component determination unit specifies a feeder holding unit that holds a feeder that stores a target circuit component based on the following two correspondences. The first correspondence is a correspondence between the position of the feeder holding unit and the feeder identification code of the feeder held in the feeder holding unit specified by the specifying control unit. The second correspondence relationship is a correspondence relationship between the component identification code and the feeder identification code stored in the component / feeder storage unit, and is stored in advance in the component / feeder storage unit. For example, as will be described in detail later in the section of the embodiment, when a circuit component is accommodated in a feeder, a barcode representing a component identification code of the circuit component is read by a barcode reader and the circuit component is accommodated. The feeder identification code of the feeder to be read is read by the writing / reading means and stored in the component / feeder storage means. The circuit component determining means specifies the type of the circuit component corresponding to the feeder holding unit through the feeder identification code. The association between the component identification code and the feeder identification code can be performed in advance with the feeder removed from the feeder holding member. A barcode representing the identification code of the feeder holding unit is attached to each feeder holding unit of the feeder holding member, and when the feeder is held by the feeder holding member, the barcode of the feeder holding unit is read by the barcode reader, and the feeder is held. It is also possible to associate the part identification code with the feeder identification code, but in that case, it is indispensable for the worker to perform the associating work when the feeder is mounted on the feeder holding member, and the preparation work is free. It cannot be avoided that the degree becomes low. According to the invention of this section, this inconvenience can be eliminated.
(27) A plurality of feeders each including at least one type of circuit component, each of which is sequentially supplied one by one, and provided with feeder-side connection portions;
A feeder-side controller provided in each of the plurality of feeders and connected to the feeder-side connecting portion;
A feeder holding member that holds the plurality of feeders in each of a plurality of feeder holding portions;
Provided corresponding to each feeder holding portion of the feeder holding member, and provided with a plurality of holding member side connection portions connected in parallel to each other, and each of the holding member side connection portions has a feeder side of each of the plurality of feeders A communication network that can send and receive signals to and from the connection part, but does not have a means for specifying the holding member side connection part
A feeder holding unit specifying means for specifying a feeder holding unit in which each of the plurality of feeders is held;
A circuit component supply system comprising: a holding member side controller provided on the feeder holding member side and connected to the communication network.
In the invention according to this section, the first communication network for exchanging general information can adopt a normal communication network as connecting a plurality of feeder-side controllers to the holding member-side controller in parallel, and a plurality of feeders. However, an object of the present invention is to obtain a circuit component supply system capable of specifying where a plurality of feeder holding portions of a feeder holding member are held.
In the circuit component supply system of this section, each of the plurality of feeders includes a feeder-side controller and a feeder-side connection unit. In addition, a holding member side controller is provided on the feeder holding member side, and holding member side connection portions are provided corresponding to the respective feeder holding portions, and these are connected to the holding member side controller in parallel. A communication network provided with a plurality of holding member side connection portions in parallel does not have a means for specifying the holding member side connection portion, and therefore it is not possible to specify which of the plurality of feeder holding portions each feeder is held by. However, communication (information exchange) between each feeder-side controller and the holding member-side controller can be managed via the feeder-side connecting portion and the holding member-side connecting portion. And since the feeder holding | maintenance part which each feeder is hold | maintained is specified by the feeder holding | maintenance part specific | specification means, the holding | maintenance member side controller is the feeder holding | maintenance part which the feeder side controller which is communicating via a communication network. It is possible to know whether it is included in the feeder held in the. Therefore, the communication network in the present invention can be realized with a simple configuration like the first communication network in the second invention, and the configuration of the circuit component supply system is simplified.
(28) The feeder holding unit specifying means is
A second feeder-side connecting portion different from the feeder-side connecting portion as the first feeder-side connecting portion provided in each of the plurality of feeders and connected to the feeder-side controller;
Separately from the holding member side connecting portion as the first holding member side connecting portion, each of the feeder holding portions is provided corresponding to each of the second feeder side connecting portions, and is independently provided on the holding portion side. A second holding member side connecting portion connected to the controller;

The invention according to this section is to obtain a suitable feeder holding unit specifying means in the circuit component supply system of the above (27).
In the circuit component supply system according to the present invention, the specific control means includes a second feeder side connection portion of each feeder, and a second holding member side connection provided in each feeder holding portion corresponding to the second feeder side connection portion. A feeder holding unit holding a target feeder is specified based on a signal exchanged with the unit.
When a signal is emitted from the second feeder side connecting portion, the signal is received by a second holding member side connecting portion provided corresponding to the second feeder side connecting portion that has issued the signal. Since each 2nd holding member side connection part is each independently connected to the holding member side controller, the holding member side controller can specify the feeder holding part by which the feeder which emitted the signal is hold | maintained. The identification control means can identify the feeder holding unit in which all the feeders are held by performing this procedure for all the second feeder side connection units.
Further, when a signal is emitted from the second holding member side connecting portion, a signal is emitted from any one of the second holding member side connecting portions. The signal is received by the second feeder side connection portion corresponding to the second holding member side connection portion that issued the signal. The feeder-side controller of the feeder provided with the second feeder-side connecting portion that has received the signal transmits data to the holding member-side controller via the communication network. In this case, each feeder-side controller transmits data on the communication network in response to reception of a signal from the second feeder-side connection unit.

A device composed of the Zθ moving device 22 and the XY moving device 24 is collectively referred to as an XYZθ moving device 26.

  The circuit component mounting apparatus 10 includes an M / C controller 516 shown in FIGS. 8 and 9 as a mounting apparatus side controller. The M / C controller 516 causes the circuit component to be mounted on the printed circuit board 16 by controlling the air pressure supplied to the suction nozzle 20, the operation of the substrate transport device 14, and the operation of the XYZθ moving device 26. In addition, the M / C controller 516 moves the suction nozzle 20 to a fixed position above the camera 32 in a state where the circuit component is sucked by the suction nozzle 20, and takes an image of the circuit component from the camera 32. It has an image measurement function for measuring the position and orientation (θ direction position) of the circuit component with respect to the suction nozzle 20. The M / C controller 516 can mount the circuit component at the correct position on the printed circuit board 16 in consideration of the position and orientation of the circuit component measured by the image measurement function.

Formed by. That is, the camera 32 images the silhouette of the circuit component.

  The circuit component supply system 50 includes a circuit component supply carriage 52 (hereinafter, abbreviated as a carriage 52) as a main body of the circuit component supply apparatus 8, and a plurality of circuit component supply apparatuses 8 that are held by the carriage 52 and constitute the circuit component supply apparatus 8 together therewith. Feeder 54 and a management terminal provided with a part / feeder storage means for storing the correspondence between circuit parts and each feeder 54. In the present embodiment, the management terminal is configured by a laptop personal computer (described later).

  FIG. 2 is a front view of the circuit component supply device 8. In this drawing, the feeder 54 is indicated by an imaginary line (two-dot chain line). The same applies to FIGS. 3 and 4 described later. The carriage 52 includes a base 60, a handle 61, a frame 62 supported by the base 60, a frame plate 63 attached to the frame 62, a feeder holding device 64 provided on the frame 62, and a frame 62. The two engaging portions 66 provided are the main components. 3 is a left side view of the circuit component supply device 8, and FIG. 4 is a right side view thereof. As shown in FIG. 3, the engaging portions 66 are provided at two locations. In FIG. 4, the handle 61 is not shown.

As shown in FIG. 1, the two engaging portions 66 are engaged with the two engaging devices 68 provided on the base frame 12 of the circuit component mounting device 10, so that the circuit component mounting device 10 and the carriage 52 are engaged. And mechanically unite. Each engagement device 68 can move in parallel in the direction in which the circuit component mounting device 10 and the carriage 52 are arranged (left and right in FIG. 1), and can be rotated about the axis parallel to the movement direction as a rotation axis. A petal-type engagement protrusion 70 is provided. The parallel movement is performed by a double-action air cylinder built in the engagement device 68. In the process of this parallel movement, the engagement protrusion 70 is rotated by a fixed angle (for example, 90 degrees) around an axis parallel to the movement direction by a cam mechanism (not shown). In a state where the circuit component mounting device 10 and the carriage 52 are not combined, the engaging protrusion 70 is in a protruding state and is in a rotational phase that can be fitted to the engaging portion 66 in the axial direction. The engaging portion 66 includes an opening having a round hole portion 71 and a pair of notches 72 extending in opposite directions from the round hole portion 71 (they face each other in the horizontal direction). When the carriage 52 and the carriage 52 are brought close together for merging, the engaging protrusion 70 passes through the notch 72 of the engaging portion 66. In this state, when air is supplied to one pressure chamber of the air cylinder and the outflow of air from the other pressure chamber is permitted, the engagement protrusion 70 is initially retracted while being rotated in the forward direction. The mating protrusion 70 engages with the engaging portion 66 so as not to be detached in the axial direction. The engagement protrusion 70 is retracted for a certain distance even after the rotation is stopped, whereby the carriage 52 is strongly attracted to the circuit component mounting apparatus 10. When the air supply state is reversed, the engagement protrusion 70 is initially protruded without rotating, allowing the carriage 52 to be separated from the circuit component mounting apparatus 10, and then the engagement protrusion 70 is protruded. It is rotated while being moved, and can be detached from the engaging portion 66 in the axial direction.

  A guide taper sleeve 74 is provided on the base frame 12 of the circuit component mounting apparatus 10. The guide taper sleeve 74 is fitted into the engagement portion 66 at a position that does not hinder the engagement between the engagement protrusion 70 and the engagement portion 66. Specifically, the engagement projection 70 is fitted to the round hole portion 71, but the engagement projection 70 is positioned on the cart 52 side in FIG. Engagement with the portion 66 is not hindered. By fitting the two sets of guide taper sleeves 74 and the round hole 71, positioning of the carriage 52 in the direction parallel to the vertical plane with respect to the circuit component mounting apparatus 10 is accurately performed.

  As shown in FIG. 2, the circuit component mounting device 10 and the carriage 52 are provided with a guide mechanism 80. The guide mechanism 80 includes two guide members 82 attached to the base frame 12 of the circuit component mounting apparatus 10 and two rollers 84 attached to the base 60 of the carriage 52. The relative position between the guide member 82 and the carriage 52 shown in FIG. 2 indicates the position after the circuit component mounting device 10 and the carriage 52 are combined. In this state, two fixed wheels 86 and two rotatable wheels 88 provided on the base 60 are separated from the floor. Further, the roller 84 is also slightly separated from the guide member 82. In a state where the circuit component mounting device 10 and the carriage 52 are not combined, the two fixed wheels 86 and the rotatable wheels 88 are both supported on the floor, and the carriage 52 can be easily moved. it can.

  When the carriage 52 is brought close to the circuit component mounting apparatus 10 for merging, the roller 84 rolls up on the slope 90 formed on the guide member 82, and the fixed wheel 86 is separated from the floor in the process. When the circuit component mounting apparatus 10 and the carriage 52 are brought closer to each other, the roller 84 rolls on the guide rail 92 formed on the guide member 82. The guide rail 92 is engaged with the roller 84 to adjust the relative position of the circuit component mounting device 10 and the carriage 52 in the horizontal direction (direction orthogonal to the paper surface of FIG. 2) to a position where the uniting can be easily performed. Fulfills the function of Thus, the fitting between the round hole 71 and the guide taper sleeve 74 can be easily started. The circuit component mounting apparatus 10 is provided with a detection device (not shown). The detection device (not shown) in the state where the round hole portion 71 and the guide taper sleeve 74 are fitted and the contact portion 94 is in contact with a projection (not shown) formed on the base frame 12 of the circuit component mounting device 10. Thus, the unity detection protrusion 95 (see FIG. 3) provided on the carriage 52 is detected. When the uniting detection projection 95 is detected by the detection device, the air cylinder of the engagement device 68 is operated, and the engagement projection 70 cannot be detached from the engagement portion 66 in the axial direction as described above. The cart 52 is engaged and pulled toward the circuit component mounting apparatus 10 to be fixed.

As shown in FIG. 1, the carriage 52 is attracted to the circuit component mounting device 10 at the engagement portion 66, and the contact surface 96 of the engagement portion 66 contacts the contact surface 97 on the engagement device 68 side. The contact portion 94 is brought into contact with a projection (not shown) formed on the base frame 12 of the circuit component mounting apparatus 10, whereby the carriage 52 is accurately positioned in the uniting direction. A plane defined by the contact surface 97 and the contact surface of the projection (not shown) (a vertical surface in the illustrated example) is a merged surface, and a direction perpendicular to the merged surface is a merged direction. The pulling force when the engaging device 68 pulls the engaging protrusion 70 toward the circuit component mounting device 10 is necessary to separate the rotatable wheel 88 from the floor and the roller 84 from the guide rail 92. It is made larger than the force, and the union of the carriage 52 and the circuit component mounting device 10 is made strong (for example, each engaging device 68 has a size of about 250 kgf≈2450 N).

One feeder 54 is held by each of the plurality of feeder holding units 100 provided in the feeder holding device 64. In the carriage 52, a feeder holding member is configured by a main body member (a base plate 106 described later) of the feeder holding device 64, and a feeder holding unit is configured by the feeder holding unit 100. As shown in FIG. 4 (right side view), the feeder holding device 64 includes four feeder holding unit groups 102 including six adjacent feeder holding units 100. Therefore, the feeder holding device 64 can hold a maximum of 24 feeders 54. In the following description, each of the four feeder holding unit groups 102 is numbered and referred to as a first to fourth feeder holding unit group 102.

Each feeder 54 includes an engaging protrusion 122 that can engage with the engaging groove 120 and the engaging member 108. When each feeder 54 is held by the feeder holding unit 100, it is translated from right to left in FIG. 2 and finally held at the position shown in FIG. The feeder 54 held by the feeder holding unit 100 is prohibited from relative movement in the direction perpendicular to the paper surface of FIG. 2 due to the engagement between the engagement protrusion 122 of the feeder 54 and the engagement groove 120 of the base plate 106. Further, the guide plate 110 attached to the base plate 106 by the plurality of support columns 124 limits the vertical movement in a plane parallel to the paper surface of FIG. As a result, engagement / disengagement between the engagement protrusion 122 and the engagement member 108 during attachment / detachment to / from the feeder holding unit 100 can be performed smoothly. In the state shown in FIG. 2, due to the engagement between the engagement member 108 and the engagement protrusion 122, the feeder 54 is prohibited from moving in the vertical direction with respect to the base plate 106.

  The feeder 54 is provided with a U-shaped engaging member 126 that urges the feeder 54 in a direction toward the frame 62 (leftward in FIG. 2) by engaging with an engaging groove 125 provided in the base plate 106.

If the operation of the lever 128 is released, the feeder 54 is moved. The feeder holding unit 100 is firmly held. In order to remove the feeder 54 from the feeder holding unit 100, the lever 128 is operated, the engaging member 126 is accommodated inside the feeder 54, and then the feeder 54 is translated in the right direction in FIG.

The carriage 52 includes an SFU controller 530 (described later, see FIG. 8) as a supply device side controller or a holding member side controller. The SFU controller 530 can exchange information with the aforementioned M / C controller 516 via the S / M communication unit 130 shown in FIG. “S” means the carriage 52 as in the case of the S / F communication unit 116 described above, and “M” means the circuit component mounting apparatus 10. The S / M communication unit 130 is provided corresponding to an M / S communication unit 552 (see FIG. 8) described later provided in the circuit component mounting apparatus 10. The M / S communication unit 552 is connected to the M / C controller 516. The SFU controller 530 is connected to the S / F communication unit 116 of all feeder holding units 100. The mutual relationship between the M / C controller 516 and each SFU controller 530 will be described later.
Further, the carriage 52 is provided with an electric power supply part 132 for receiving supply of various electric power from the circuit component mounting apparatus 10 and an air supply part 134 for receiving supply of compressed air.

  As shown in FIG. 2, the feeder 54 can mount up to two component storage reels 150 that store a plurality of circuit components of the same type. The component storage reel 150 includes a tape-shaped storage container 152 that stores circuit components, and a cover film 154 that is bonded to the tape-shaped storage container 152 so that the circuit components in the tape-shaped storage container 152 do not fall off. A storage tape 156 is wound around. The cover film 154 adhered to the tape-like container 152 is slightly closer to the component-receiving reel 150 side (position where the suction nozzle 20 is shown in FIG. 1) than the position where the circuit component is sucked by the suction nozzle 20 (the position where the suction nozzle 20 is shown in FIG. 1). It is peeled off from the tape-like container 152 on the right side in FIG. The tape-like container 152 that has finished supplying the circuit components is sent to the circuit component mounting apparatus 10 side (left side in FIG. 2). The pitch of the feeding is made to coincide with the component housing pitch of the circuit components in the longitudinal direction of the tape-shaped container 152. The tape-like container 152 that has finished supplying the circuit components is guided by a tape guide 160 to a cutting machine 162 that is a cutting means for cutting the tape. The tape guide 160 and the cutting machine 162 are attached to the frame 62. The cutting machine 162 cuts the tape-shaped container 152, and the cut pieces of the tape-shaped container 152 are attached to the lower part of the frame 62 and stored in the cut-piece container 164. In addition, the process of the cover film 154 peeled from the tape-shaped storage container 152 is mentioned later.

That is, the rotation of the motor 202 is transmitted to the sprocket 214, the pinch roller 220, and the pinch roller 222.

  The drive belt 210 has a passage route defined by a plurality of guide rollers 224. Further, since the motor 202 is a pulse motor, the rotation angle of the sprocket 214 can be controlled by the number of pulses applied to the motor 202. This pulse is supplied by an F / D controller 540 (described later, see FIG. 8) which is a feeder-side controller. Note that the rotation angle between the motor 202 and the sprocket 214 differs by the same ratio as the product of the gear ratio between the drive gear 204 and the driven gear 206 and the radius ratio between the drive pulley 208 and the driven pulley 212. The tape-like container 152 is formed with engagement holes that are continuous at regular intervals in the longitudinal direction, and is engaged with protrusions formed at equal intervals on the outer periphery of the sprocket 214. In order to ensure the engagement, the cover 225 prevents the tape-like container 152 from being lifted from the sprocket 214.

  When the sprocket 214 rotates, tension is generated in the component storage tape 156 due to frictional resistance when the component storage reel 150 is rotated, rotational friction of the guide roller 224, and the like. In this feeder 54, by changing the number of pulses applied to the motor 202, the component accommodating tape 156 can be easily fed at an arbitrary feed amount regardless of the magnitude of such disturbance factors. Therefore, even if the pitch in which the circuit components are stored in the component storage tape 156 changes, it can be easily handled. The pinch rollers 220 and 222 are in contact with each other at a preset contact pressure, and a cover film 154 peeled off from the component housing tape 156 is sandwiched between them as shown in FIG. The pinch rollers 220 and 222 are adhered to the component receiving tape 156 by sending the already peeled portion of the cover film 154 to the component receiving reel 150 when the component receiving tape 156 is sent by the sprocket 214. The cover film 154 is removed in order. The feed amount of the cover film 154 is made larger than the feed amount of the component housing tape 156 by the sprocket 214. And since the peeling position of the cover film 154 from the component accommodation tape 156 is prescribed | regulated by the drawing slit of the cover film 154 formed in the cover 225, since the excess of the feed amount of the cover film 154 is the pinch roller 220, The cover film 154 between the cover 225 and the pinch rollers 220 and 222 is always kept in tension by being absorbed by the slip of the cover 222 against the cover film 154.

Similarly, the other driving device 201 includes a motor 226, a driving gear 228, a driven gear 230, a driving pulley 232, driving belts 234 and 236, a driven pulley 238, pinch rollers 240 and 242, a guide roller 244, and the like. Yes. The driving device 201 is also provided with the same components as the sprocket 214 and the driven pulley 212 described above in a position overlapping with each other in FIG. As shown in FIG. 5, the cover films 154 sent by the pinch rollers 220 and 222 and the pinch rollers 240 and 242, respectively, pass through the pipe 246 attached in a state where the axial direction is the vertical direction in FIG. Then dropped down. Therefore, in a state where the feeder 54 is held by the feeder holding unit 100, the cover film 154 to be discarded is stored on the base 60 of the carriage 52. An air nozzle 248 is provided to smooth the passage of the cover film 154 in the pipe 246. When at least one of the motor 202 and the motor 226 is rotated, compressed air enters the pipe 246. It is made to blow in from the upper part toward the lower part. The compressed air is supplied to the air nozzle 248 by opening the solenoid valve 250. The solenoid valve 250 is controlled by the F / D controller 540.

  The feeder 54 is provided with some operation switches (not shown) connected to the F / D controller 540. These operation switches include one for rotating the motor 202 and the motor 226 independently in both forward and reverse directions, one for determining the rotational speed of each motor when supplying circuit components, and one circuit component. For determining the rotation angle of each motor for each supply, and for determining whether or not each of the driving devices 200 and 201 is to be operated. Based on the state of these operation switches, the F / D controller 540 can control each part of the feeder 54.

  As shown in FIG. 6, the lever 128 of the feeder 54 is urged by a spring 252 as an urging member so as to rotate counterclockwise in FIG. 6 about the fulcrum 254. This urging force is transmitted to the engaging member 126 by the link mechanism 256, and the engaging member 126 is projected outside the feeder 54 when the lever 128 is not operated. In order to house the engaging member 126 in the feeder 54, the lever 128 is rotated clockwise in FIG.

  FIG. 7 is an enlarged front view of a main part of the feeder holding unit 100 in a state where the feeder 54 is held. The feeder 54 is optically connected to the S / F communication unit 116 of the feeder holding unit 100 in the F / S communication unit 270, and communication between the SFU controller 530 and the F / D controller 540 is performed via this connection unit. Done. Further, the feeder 54 includes an air supply part 272 that fits with the air supply part 112 of the feeder holding unit 100 and supplies compressed air to the solenoid valve 250 described above. Furthermore, a power supplied unit 274 is provided that is electrically connected to the power supply unit 114 and supplies power to the F / D controller 540, the motor 202, and the like. The feeder 54 has power used for the F / D controller 540 (for example, power whose voltage is DC 5 volts) and power used for operating the motors 202 and 226 and the solenoid valve 250 (for example, , Power having a voltage of DC 24 volts). These electric powers are supplied from the circuit component mounting apparatus 10 to the carriage 52. In addition, when the carriage 52 and the circuit component mounting apparatus 10 are not combined, the carriage 52 is provided with a second power supply unit (not shown) for receiving power supply. In the preparatory work performed prior to the circuit component mounting work, when the circuit component mounting apparatus 10 and the carriage 52 are not combined, the power supplied from the second power supplied portion is used.

The F / S communication unit 270 includes light emitting elements 280, 282, 284 and a light receiving element 286. The S / F communication unit 116 includes light receiving elements 290, 292, and 294 that respectively receive light emitted from the light emitting elements 280, 282, and 284 of the F / S communication unit 270, and a light receiving element of the F / S communication unit 270. And a light emitting element 296 that emits light to 286. A set of the light emitting element 282 of the F / S communication unit 270 and the light receiving element 292 of the S / F communication unit 116 is used when transmitting a signal from the F / D controller 540 to the SFU controller 530. The pair with the light receiving element 294 is used as an auxiliary when transmitting the information. Specifically, the light received by the light receiving element 292 is recognized as a communication signal only when the light receiving element 294 of the S / F communication unit 116 receives light. This is a measure for preventing disturbance light from being erroneously recognized as a communication signal when the feeder 54 is not held. This measure is simply referred to as an erroneous communication prevention measure. The pair of the light receiving element 286 of the F / S communication unit 270 and the light emitting element 296 of the S / F communication unit 116 is used when a signal is transmitted from the SFU controller 530 to the F / D controller 540.
In the present embodiment, the first holding member side connection portion is configured by the light receiving elements 292 and 294 and the light emitting element 296 of the S / F communication unit 116, and the second holding member side connection portion is the light receiving element 290. It is comprised by. Further, the first feeder side connecting portion is configured by the light emitting elements 282 and 284 and the light receiving element 286 of the F / S communication unit 270, and the second feeder side connecting portion is configured by the light emitting element 280.

Next, the mutual relationship between the aforementioned M / C controller 516, SFU controller 530 and F / D controller 540 will be described.
FIG. 8 is a system diagram showing the configuration of the electrical control unit of the circuit component mounting system 500. The circuit component mounting system 500 includes a circuit component mounting device 10, two carriages 52 combined with the circuit component mounting device 10, a plurality of feeders 54 held by each of the carts 52, and the above-described management terminal. A laptop computer 502 (hereinafter abbreviated as “LT computer 502”) and a host computer 504 are provided.
The host computer 504 manages the circuit component mounting apparatus 10 and stores a circuit component database including circuit component information that is information related to the circuit components. The content of the circuit component database is obtained by associating circuit component information with the content of the component identification code attached to the component supply tape 156 in which the circuit component is accommodated. The component identification code is converted into a barcode, and a component barcode seal 506 on which the barcode is printed is attached to the component receiving reel 150 (see FIG. 5). Further, in the circuit component information, a component storage position, a component storage pitch, a remaining number of components, etc., indicating the storage position of the circuit component in the component storage tape 156 (for example, the relative position of the reference point of the circuit component with respect to the tape-shaped storage container 152). Information is included. Other information may include information such as part type, part model, part manufacturing date, part manufacturer, part inventory, part usage schedule, part usage schedule, and the like. It is assumed that the circuit components are stock-managed in a state where they are housed in the component housing reel 150.

Two carriages 52 can be combined with the circuit component mounting apparatus 10 of the circuit component mounting system 500. In other words, the circuit component mounting device 10 includes two sets of devices (collectively referred to as united devices) including the engaging device 68, the M / S communication unit 552, and the like. And each cart 52 can be united in either of two uniting devices. Similarly, the feeder 54 can be held in any of the plurality of feeder holding units 100 of the two carriages 52. Therefore, the position where each carriage 52 is united with the circuit component mounting apparatus 10 and the position where each feeder 54 is held by the carriage 52 can be changed.
On the other hand, the M / C controller 516 of the circuit component mounting apparatus 10 needs to know the position where the target circuit component is supplied when the circuit component to be mounted is held in the suction nozzle 20 and mounted on the printed circuit board 16. There is. This is because the XYZθ moving device 26 cannot be controlled unless this position is known. Therefore, if the position where each carriage 52 is combined with the circuit component mounting apparatus 10 and the position where each feeder 54 is held by the carriage 52 are changed to positions different from the original correct positions, It will be mounted at a position where it should not be mounted. The circuit component mounting system 500 is a system that can prevent such erroneous mounting in advance as will be described below.

As shown in FIG. 8, the host computer 504 and the circuit component mounting apparatus 10 are connected by a host network 510. The host network 510 is realized, for example, by a LAN (Local Area Network) having a network structure such as a bus type or a loop type. In many cases, these are networks that transmit serial data using a single communication line, but may be a bus used as an internal bus of a computer, such as a VME bus or a PCI bus. In the description, it is assumed that the host network 510 is configured as a VME bus. In any case, the host computer 504 and the circuit component mounting apparatus 10 have a function of exchanging all kinds of information including circuit component information.

The circuit component mounting apparatus 10 communicates with the host computer 504, control of the substrate transport device 14, control of the XYZθ moving device 26, suction control of circuit components by the suction nozzle 20, communication with the SFU controller 530, F / D controller 540. And the like are performed by the M / C controller 516. The circuit component mounting apparatus 10 includes an M / C network 520 and an SPID network 522 connected to the M / C controller 516. These connection forms will be described later.
Each of the two carriages 52 includes the SFU controller 530 as described above, and performs communication with the M / C controller 516, communication with the F / D controller 540, and the like. The SFU controller 530 is connected to an SFU network 534 as a first communication network and an FPID network 536 as a second communication network. These connection forms will be described later.
Further, the F / D controller 540 of the feeder 54 performs communication with the M / C controller 516, communication with the SFU controller 530, control of the motors 202 and 226, and the like.

  By using the M / C network 520 and the SFU network 534, the M / C controller 516, each SFU controller 530, and each F / D controller 540 can exchange information with each other. However, the M / C network 520 and the SFU network 534 have no means for acquiring the mutual connection position relationship. As described above, each feeder 54 can be held by any feeder holding unit 100 of each carriage 52, and each carriage 52 has two sets of uniting devices (engaging devices 68, M / S) of the circuit component mounting device 10. Each SFU controller 530 and each F / D controller 540 can be connected to each other at a plurality of positions, but the M / C network 520 and the SFU network 534 are connected to each other. As is apparent from the configuration shown later, there is no means for acquiring the connection positional relationship between the controllers. That is, when the M / C controller 516 and one of the SFU controllers 530 communicate with each other, the M / C controller 516 has the SFU controller 530 that is performing communication merged with either of the two coalescing devices. It cannot be specified whether the vehicle is provided on the carriage 52. Similarly, it is not possible to specify which of the 24 feeder holding units 100 is capable of holding up to 24 feeders 54 in each carriage 52. Therefore, the SPID network 522 is provided for specifying the former position, and the FPID network 536 is provided for specifying the latter position.

  FIG. 9 is a system diagram more specifically showing a configuration related to communication between the circuit component mounting apparatus 10 and the carriage 52. 9, the M / C network 520 includes a twisted pair line 546, a terminating resistor 548, a bus driver 550, an optical link driver 551, a part of an M / S communication unit 552, and the like. The M / S communication unit 552 has the same configuration as the S / F communication unit 116 shown in FIG. That is, the M / S communication unit 552 includes the light receiving elements 290, 292, 294 and the light emitting element 296. Among them, the M / C network 520 includes light receiving elements 292 and 294 and a light emitting element 296. As the bus driver 550, for example, one that conforms to RS-485 can be used, and is used to connect the M / C controller 516 to the twisted pair line 546. The optical link driver 551 has a function of connecting the M / S communication unit 552 to the twisted pair wire 546 and performing a receiving-side measure (processing) among the above-described erroneous communication preventing measures. In the M / C network 520, the bus driver 550 and the optical link driver 551 can be disposed at any position of the twisted pair line 546. Further, as long as the number is determined by the drive capability of the bus driver 550 and the optical link driver 551, they can be arranged at any number and at any position.

  The SFU network 534 includes a twisted pair line 560, a terminating resistor 562, a bus driver 564, an optical link driver 566, 568, a part of the S / M communication unit 130, a part of the S / F communication unit 116, and the like. The S / M communication unit 130 has the same configuration as the F / S communication unit 270 shown in FIG. That is, the S / M communication unit 130 includes light emitting elements 280, 282, 284 and a light receiving element 286. The SFU network 534 includes light emitting elements 282 and 284 and a light receiving element 286 among these elements. The bus driver 564 is the same as the bus driver 550 constituting the M / C network 520, and the optical link driver 568 is the same as the optical link driver 551. The optical link driver 566 is paired with the optical link driver 551, and has a function of performing a transmission side measure (process) among the above-described erroneous communication prevention measures. The SFU network 534 includes light receiving elements 292 and 294 of the S / F communication unit 116 and a light emitting element 296, which are respectively light emitting elements 282 of the F / S communication unit 270 provided in the feeder 54. , 284 and the light receiving element 286. The light emitting elements 282 and 284 and the light receiving element 286 of the F / S communication unit 270 are connected to the F / D controller 540 via the optical link 570. Similar to the optical link driver 566, the optical link 570 has a function of performing the transmission side measures (processing) among the above-described erroneous communication prevention measures, but performs transmission / reception of signals to / from the twisted pair line. It does not have a bus driver function that is a function of

Various communication methods for data communication using a network such as the M / C network 520 and the SFU network 534 have been proposed. In the circuit component supply system 50, a CSMA / CD that is generally used is generally used. (Carrier
Sense Multiple Access with Collision Detection) is employed. Since the CSMA / CD method is well known, a detailed description of the contents is omitted, but only useful attributes will be described in the following description.

In order to share one communication line among a plurality of nodes, in the CSMA / CD system, each node performs self-regulation so that the plurality of nodes do not transmit data at the same time. In other words, data collision is avoided by time sharing. Here, the “node” is a concept that generally indicates an entrance to a communication network, and corresponds to the M / C controller 516, the SFU controller 530, and the F / D controller 540. The “self-regulation” described above mainly includes the following two contents.
(i) Transmission restriction based on carrier detection Each node detects whether or not there is a signal in communication (referred to as a carrier) on the network, and when there is no carrier, the node that has detected it can transmit. Note that only with this transmission restriction, there may be a plurality of nodes that have detected that no carrier exists at the same time, so a plurality of transmission data may collide on the network.
(ii) Transmission / reception regulation based on collision detection When data transmitted from one node collides with data transmitted from another node, and the collision is actually detected, the transmitted data is invalid After informing this to other nodes, the data is transmitted again. When the node receiving the data is notified that the received data is invalid, the node discards the received data.
The data to be transmitted is basically received by all nodes including the node that transmitted the data, but the transmission data includes address data that specifies the receiving node that should receive the data. . The address data is unique to each node, and each node knows in advance the address data of all nodes including itself. The receiving node detects this address and determines whether or not it is data to be received.

10 and 11 are flowcharts showing an example of a method for specifically realizing the above two self-regulations. FIG. 10 shows the contents of processing performed by the transmitting node, and FIG. 11 shows the contents of processing performed by the receiving node. ing. Note that the difference between the “transmission side” and the “reception side” is only a difference in whether or not there is data to be transmitted, and the individual nodes are not essentially different.
First, the processing on the transmission side will be briefly described with reference to FIG. First, in step 10 (hereinafter abbreviated as S10. The same applies to other steps), it is detected whether or not there is a carrier on the communication line. This is done by acquiring the voltage change state on the signal line. If the change state of the voltage on the signal line indicates that no carrier exists, it is determined that transmission is possible, and data is transmitted on the communication line in S12. The node on the transmission side always monitors the data indicated by the carrier on the communication line during the period of data transmission. When the data transmission is completed, it is determined in S14 whether or not the data transmitted by itself matches the data indicated by the carrier monitored during the transmission. If they match, the data transmission is considered to have been completed normally and the transmission is completed. If they do not match, a process of invalidating the transmitted data is performed in S16. This is done by retransmitting data indicating that the transmitted data is invalid (referred to as invalidation data). This invalidation data is received by all reception side nodes, and each reception side node discards the data received immediately before in response to the reception of invalidation data.

Next, processing on the receiving side will be briefly described with reference to FIG. Basically, each node receives all the carriers on the communication line, but the receiving side node is a node that knows that the carrier on the signal line is not transmitted by itself. First, when correct data is received in S20 (when invalidation data is not received), in S22, whether or not the data is addressed to itself is determined based on the address data included in the received data. . If the result is YES, in S24, the received data is stored in the reception data buffer, and the reception process is terminated. Data in the reception data buffer is read and used by another process. If the received data is not the data that should be received, the determination result in S22 is NO, and the data is not stored in the received data buffer but ignored.
Note that the processes shown in FIGS. 10 and 11 are illustrated by extracting only basic portions, and various other processes are performed in the actual CSMA / CD system. An example is the determination of the retransmission wait time when transmission data collides. However, since there is little relation to the invention of the present application, a detailed description thereof will be omitted. As described above, the M / C controller 516, the SFU controller 530, and the F / D controller 540 are connected by the M / C network 520 and the SFU network 534 mainly composed of one communication line to transmit information. The configuration of the circuit component mounting apparatus 10 can be simplified while avoiding a decrease in capability.

As described above, each controller as a node needs to have unique address data. These address data are collectively referred to as node IDs. Each of the M / C controller 516, the SFU controller 530, and the F / D controller 540 has a unique MID, SID, and FID as node IDs (see FIG. 8). Each node ID is stored in a storage device (not shown) (for example, PROM, EPROM, E ² PROM, etc.) built in each controller. Therefore, the M / C controller 516, the SFU controller 530, and the F / D controller 540 can communicate with each other in any combination. At that time, the set of the M / S communication unit 552 and the S / M communication unit 130 functions as a bridge that connects the M / C network 520 and the SFU network 534. The set of the S / F communication unit 116 and the F / S communication unit 270 functions to connect the F / D controller 540 of each feeder 54 to the SFU network 534. When communication is performed between the SFU controller 530 or the F / D controller 540 and the host computer 504, the M / C controller 516 functions as a so-called gateway.
Each feeder 54 includes a unique feeder identification code, but the above-mentioned FID is also used as the feeder identification code. Therefore, a storage device (not shown) incorporated in the F / D controller 540 constitutes a feeder identification code holding unit or an identification code storage unit. A feeder bar code seal 572 printed with a barcode indicating the content of the FID, that is, the feeder identification code is attached to the side plate 198 of the feeder 54 (see FIG. 5).

  As shown in FIG. 9, the SPID network 522 includes a light receiving element 290 of each M / S communication unit 552 and an electric wire 574 that connects the light receiving elements 290 to the M / C controller 516 independently. The fact that the light receiving elements 290 are independently connected to the M / C controller 516 means that the M / C controller 516 has a light emitting element 280 of the S / M communication unit 130 provided corresponding to each of the light receiving elements 290. This means that it is possible to know the light emission state of each independently. The FPID network 536 also has the same configuration as the SPID network 522, and includes a light receiving element 290 of each S / F communication unit 116, and an electric wire 576 that independently connects the light receiving elements 290 to the SFU controller 530. Is included. Thereby, the SFU controller 530 can know the light emission state of the light emitting element 280 of the F / S communication unit 270 independently of each other. The SPID network 522 includes two electric wires 574, whereas the FPID network 536 includes 24 electric wires 576 corresponding to the number of feeder holding units 100 of one carriage 52.

  FIG. 12 is a configuration diagram showing an embodiment for reducing the number of electric wires 576 of the FPID network 536. The FPID network 536 includes an encoder 578. The input of the encoder 578 is connected to the light receiving elements 290 of the 24 S / F communication units 116 provided corresponding to the 24 feeders 54, and the output is connected to the SFU controller 530 by the five electric wires 576. . When the light receiving element 290 connected to any one of the 24 inputs detects light, the encoder 578 generates a 5-bit binary number corresponding to the position of the input. The SFU controller 530 specifies the light receiving element 290 that has detected the light based on the binary number. If a 5-bit binary number is converted to a decimal number, 32 values (greater than 24) from 0 to 31 can be expressed, so only five wires 576 are required. However, as will be described later, the plurality of light receiving elements 290 are configured not to detect light at the same time. Since this connection requires only the use of the five electric wires 576, if the encoder 578 is provided close to the feeder holding unit 100, the length of the wiring in the carriage 52 can be reduced as a whole. Such a configuration becomes more useful as the number of feeder holding units 100 included in one carriage 52 increases. In the present embodiment, the rate of reduction of the number of electric wires 576 is 5/24, but if the number of feeder holding units 100 is 100, it becomes 7/100 (the output of the encoder 578 is only 7 bits). ). In general, if the number of the electric wires 576 is increased by n, the feeder holding unit 100 that is 2 to the power of n can be handled.

Next, the operation of the circuit component mounting system 500 using the configuration described above will be described. First, the following procedure (1) is executed.
Procedure (1): Pre-processing The host computer 504 stores the circuit component information of all the circuit components to be mounted and the component identification codes (contents of the component bar code seal 506) of the circuit components in association with each other. Create a parts database. This circuit component database needs to be created in advance by an operator. The circuit component information includes information such as the above-described component storage position, component storage pitch, and remaining component number. Therefore, the circuit component database is specifically created as table data as an example shown in FIG. Procedure (1) must be completed before the processing of each procedure described later is performed.

  A control program executed by the M / C controller 516 for controlling the air pressure supplied to the XYZθ moving device 26 and the suction nozzle 20 is created in advance by a programmer and stored in a storage device of the host computer 504. It shall be. This control program is created individually for each of various printed circuit boards. In the control program, the circuit component name of each circuit component is associated with the mounting position (X, Y) of the circuit component on the printed circuit board. Any name can be used as the circuit component name. For example, the model of each circuit component, an abbreviated symbol in a circuit diagram, and the like can be used. In the latter, for example, capacitors are represented by C1, C2, etc., resistors are represented by R1, R2, etc., and integrated circuit components are represented by IC1, IC2, etc. In this way, the fact that the control program is created based on the names of circuit components that can be easily understood by circuit designers and programmers means that the control program itself can be created and maintenance (control program modification) that can be performed thereafter. make it easier.

  A control program (a circuit component name and a mounting position on a printed circuit board associated with each other) created by a programmer does not include information on a position where each circuit component is supplied as it is. This positional information is indispensable for controlling the mounting of circuit components by the M / C controller 516. Therefore, in this state, the control program is not completed. A supply position optimization program is executed by the host computer 504 in order to add information on the position at which circuit components are supplied to the control program. The supply position optimization program uses each circuit component mounting position on the printed circuit board (this position has already been determined for each type of printed circuit board) and the contents of the above-described circuit component database. The position where the component is supplied is associated with the component identification code of the component receiving reel 150 that stores each circuit component. At the time of the association, the position where each circuit component is supplied is optimized so that the time required for mounting all the circuit components on one printed circuit board is as short as possible.

By the above optimization, one type of circuit component may be determined to be supplied separately by the plurality of feeders 54. Such a determination is often made when a plurality of one type of circuit components are mounted on one printed circuit board and the positions of the same kind of circuit components on the printed circuit board are separated from each other. That is, in order to shorten the time for mounting all circuit components on one printed circuit board, generally, the distance that the suction nozzle 20 is moved by the XY moving device 24 while all circuit components are mounted can be shortened. That's fine. As a result of such a shortening of the distance, generally, (i) each circuit component is mounted sequentially from the mounting position on the printed circuit board, and (ii) the position where each circuit component is mounted, and each of those positions. The positions where the circuit components are supplied are close to each other. That is, the position where each circuit component is supplied is determined depending on the mounting position of each circuit component on the printed circuit board. Therefore, for example, when a plurality of the same circuit components are mounted at relatively spaced positions on the printed circuit board, the circuit components may be supplied by a plurality of feeders 54 close to each of the plurality of mounting positions. (In other words, if the number of feeders 54 to be held is smaller than the number of feeder holding units 100, the feeders 54 are not necessarily held by the feeder holding units 100 adjacent to each other. Can also be held in). If such a supply is performed, it may be possible to reduce the mounting time of the circuit components as a whole, compared to a case where the supply is performed by only one feeder 54. This is effective even when a so-called XY type mounting machine (the mounting machine 18 is an example thereof) is used, but a so-called index type mounting machine (for example, Japanese Patent Laid-Open No. 7-15179 described later). When the described apparatus is used, it is more effective (described later).

Since the feeder 54 can be mounted with up to two component storage reels 150, the supply position optimization program determines that each of the two component storage reels 150 mounted on the feeder 54 is
It is also determined which of the two mounting positions of the feeder 54 should be mounted (as a result, two component storage reels 150 can be mounted on each feeder 54 or one component storage reel 150 can be mounted. Only may be worn). As described above, the position where each circuit component is supplied includes the combined position of the circuit component mounting apparatus 10 and each carriage 52, the holding position of the feeder 54 in each carriage 52, and the mounting of the component receiving reel 150 in each feeder 54. Can be specified by position. The supply position of each circuit component designated in this way is simply referred to as a circuit component supply position. As a result of optimization by the supply position optimization program, the control program knows the correspondence between each circuit component supply position and each component identification code. Based on the correspondence between each circuit component supply position determined as described above and each component identification code (simply referred to as the supply position / component identification code correspondence), the operator (2) In step (4), each component receiving reel 150 is mounted on the feeder 54, each feeder 54 is held at a corresponding holding position of the carriage 52, and each carriage 52 is combined at a position corresponding to the circuit component mounting apparatus 10. Let This operation is simply referred to as mounting and holding uniting operation. As will be described later, the circuit component mounting system 500 can cause the worker to correct the mounting / holding uniting operation by detecting the error in the mounting / holding uniting operation and notifying the operator. System.

The control program including the supply position / part identification code correspondence information is transferred to the M / C controller 516 via the host network 510. The M / C controller 516 performs mounting work according to this control program.
The control program created by the programmer directly associates the circuit component supply position (position where each circuit component is supplied) and the mounting position on the printed circuit board instead of the circuit component name. May be. That is, the circuit component supply position is directly input by the programmer (such a program corresponds to a program created in a conventional circuit component mounting system). The circuit component supply position is also determined by the above-described supply position optimization program, but in this way, the programmer may determine it directly. Even in this case, when an operator mistakenly performs the mounting and holding work, it can be detected and reported as in the case where the circuit component name and the mounting position on the printed circuit board are associated with each other. .

Procedure (2): Setting of component receiving reels One or two component receiving reels 150 for storing circuit components to be mounted on the printed circuit board are set in each feeder 54. When each component receiving reel 150 is set, the contents of the component barcode seal 506 attached to the component receiving reel 150 are sequentially read, and the feeder barcode seal attached to the feeder 54 on which the component containing reel 150 is set. The contents of 572 are also read. These two bar code stickers are read by a bar code reader (not shown) connected to the LT computer 502. The LT computer 502 sequentially creates table data as shown in FIG. 14 as an example in order to associate the contents of the three bar code stickers read in succession with each other. This table is referred to as a circuit component / feeder correspondence table.

The interface 600 shown in FIG. 8 is connected to the LT computer 502, and the interface 600 and the interface 602 connected to the SFU network 534 of each carriage 52 are connected, so that the LT computer 502 is connected to each carriage. 52 SFU networks 522 are independently connected to each other. The interface 600 and the two interfaces 602 are connected via a router (not shown). However, in some cases, the interface 600 and the interface 602 of the cart 52 are directly connected to the cart 52 that is not combined with the circuit component mounting apparatus 10 without using the router. With these configurations, the circuit component / feeder correspondence table (FIG. 14).
The content of the reference) can be transmitted to each SFU controller 530. Each SFU controller 530 stores the contents of the received circuit component / feeder correspondence table in a built-in storage device (for example, RAM). Therefore, even when the carriage 52 is not combined with the circuit component mounting apparatus 10, each SFU controller 530 has a feeder 54 held by the carriage 52 including itself and a component receiving reel mounted on the feeder 54. The relationship with the 150 component identification codes can be known in advance, and the preparatory work can be efficiently performed as a whole. In the present embodiment, the part / feeder storage means is configured by the part storing the circuit part / feeder correspondence table of the LT computer 502 or the storage device built in the SFU controller 530.

  The circuit component / feeder correspondence table shown in FIG. 14 includes two component identification codes corresponding to each FID, corresponding to the fact that the feeder 54 can mount up to two component receiving reels 150. These two component identification codes are referred to as a component identification code 1 and a component identification code 2. The component identification code 1 is made to correspond to the circuit component supplied by the driving device 200 of the feeder 54, and the component identification code 2 is 201 corresponds to the circuit component supplied by 201. Whether the content of the component barcode seal 506 of the two component receiving reels 150 is the component identification code 1 or the component identification code 2 is determined according to the reading order of the two component barcode seals 506 in this embodiment. Although it is determined, other forms may be adopted. In this embodiment, if there is an error in the order of reading by the bar code reader, it is read again by the bar code reader, and the contents of the circuit component / feeder correspondence table are directly changed by directly operating the LT computer 502. As a result, the contents of the circuit component / feeder correspondence table stored in the LT computer 502 can be corrected.

Procedure (3): Feeder setting The feeder 54 that has undergone the processing of procedure (2) is held in a predetermined feeder holding unit 100. The arrangement when each feeder 54 is held in the feeder holding device 64 is related to the supply order of circuit components, that is, the mounting order, and has a great influence on the time required for mounting work on one printed circuit board. Therefore, as described above, the feeder holding unit 100 in which each feeder 54 is to be held is determined in advance based on the mounting order, and each feeder holding unit 100 holds the feeder 54 as planned. Note that whether or not each feeder 54 is held in the feeder holding unit 100 as planned can be detected by the SFU controller 530 as described later. As will be described later, this detection result (including the contents of correction) can be displayed on a display (not shown) provided in the LT computer 502 or the carriage 52, and the operator makes an error according to the contents of the display screen. Correction is performed so that the feeder held at the position is held at the correct position.
Conventionally, in a device corresponding to the circuit component mounting device 10, circuit component mounting work has always been performed based on this predetermined layout. Therefore, if an error occurs in the placement of each feeder 54, Installation was not performed correctly. Although it is desirable in the circuit component supply system 50 that each feeder 54 is held by the feeder holding unit 100 as planned, it is not essential. Even if the holding positions of some of the feeders 54 are not as planned, the mounting operation can be performed correctly for the reasons described later. Therefore, if the mounting time is not greatly affected, there is an error in the arrangement of the feeders 54. Even so, it is not essential to correct it.

Procedure (4): Integration of the circuit component supply device and the circuit component mounting device The circuit component supply device 8 (directly the carriage 52) and the circuit component mounting device 10 are combined. Whether the two carriages 52 are combined with the circuit component mounting apparatus 10 at the correct position is detected by the M / C controller 516 as will be described later. The detection result is displayed on a display (not shown) provided in the circuit component mounting apparatus 10. In the case of being combined at an incorrect position, the operator can correct the cart 52 and the circuit component mounting apparatus 10 to be combined at the correct position according to the display content of the display. Furthermore, it is possible to eliminate the need for such correction for reasons described later.
Note that either of the processing of the procedure (3) and the procedure (4) may be performed first. Further, the other process may be performed in the middle of one process of the procedure (3) and the procedure (4).

Procedure (5): Creation of cart / merging device correspondence table The M / C controller 516 creates a cart / merging device correspondence table, an example of which is shown in FIG. This is a table indicating which one or two carriages 52 are combined with the circuit component mounting apparatus 10 by any of the above-described two combining apparatuses. This table is created using the SPID network 522 as follows, for example. (i) The SFU controller 530 provided in each carriage 52 first transmits a signal indicating that it has been activated to the M / C controller 516 when the supply of electric power is started by combining. (ii) The M / C controller 516 issues a command (with the SID of the SFU controller 530) to the SFU controller 530 that has transmitted the activation signal. The command is “light up the light emitting element 280 of the S / M communication unit 130”. (iii) Upon receiving the command, the SFU controller 530 causes the light emitting element 280 of the S / M communication unit 130 to emit light. (iv) The M / C controller 516 detects the states of the light receiving elements 290 of the two M / S communication units 552 belonging to the two coalescing devices. Then, the carriage 52 merged with the circuit component mounting apparatus 10 by the merge apparatus to which the M / S communication unit 552 including the light receiving element 290 that detects the light belongs transmits a signal indicating that it has been activated in (ii). The SFU controller 530 is specified. This is possible because each light receiving element 290 is independently connected to the M / C controller 516 by the SPID network 522. Based on this identification result, the M / C controller 516 creates the cart / union device correspondence table shown in FIG.

Further, the table may be created as follows. (i) The M / C controller 516 periodically issues a command on the M / C network 520. The command is sequentially transmitted with the SID of the SFU controller 530 included in the carriage 52 that may be combined with the circuit component mounting apparatus 10. The contents of the command are the same as those in the above-described procedure, which is “Let the light emitting element 280 of the S / M communication unit 130 emit light”. (ii) When this command is received by the SFU controller 530 belonging to the united cart 52, the SFU controller 530 checks whether the SID attached to the command matches its own SID, If they match, the light emitting element 280 of the S / M communication unit 130 is caused to emit light. However, nothing happens if the carriage 52 including such an SFU controller 530 is not united. (iii) The M / C controller 516 detects the state of the light receiving element 290 of the M / S communication unit 552 provided corresponding to the two coalescing devices. When light is detected by the light receiving element 290 of any M / S communication unit 552, a command is emitted immediately before by the coalescing device corresponding to the M / S communication unit 552 including the light receiving element 290 that has detected the light. It is specified that the carriage 52 provided with the previous SFU controller 530 is combined.

Procedure (6): Feeder / holding unit correspondence table creation Each SFU controller 530 creates a feeder / holding unit correspondence table, an example of which is shown in FIG. This is a table indicating which of the 24 feeder holding units 100 described above, that is, the holding positions of the plurality of feeders 54, each of the feeders 54. The FPID network 536 is used to create this table. This table can be created, for example, using a procedure similar to one of the two procedures for creating the cart / union device correspondence table described in step (5). It should be noted that the number of included data is different between the cart / union device correspondence table and the feeder / holding unit table. This difference is the difference between the number of carriages 52 and the number of feeders 54 that can be held by each carriage 52. As described above, although the number of objects to be found is different, by using the SPID network 522 and the FPID network 536, the position of each of the plurality of objects can be specified.

Procedure (7): Creation of circuit component / holding unit correspondence table The LT computer 502 is connected to the SFU network 534 of each of the two carts 52 using the interfaces 600 and 602 (and a router (not shown)), and the procedure (2). The contents of each circuit component / feeder correspondence table created in step S1 are transmitted to each SFU controller 530. The LT computer 502 functions as one node while being connected to each SFU network 534, and has address data for this purpose. Each SFU controller 530 receives the contents of the received circuit component / feeder correspondence table (see FIG. 14) and the contents of the feeder / holding unit correspondence table unique to each carriage 52 created in the process of step (6) (FIG. 16). And a circuit component / holding unit correspondence table, an example of which is shown in FIG. 17, based on the storage contents of the storage means. The contents of the circuit component / feeder correspondence table and the feeder / holding unit correspondence table both include FID data. Of these two correspondence tables, the circuit component having the same FID and the feeder holding unit 100 are included. And a circuit component / holding unit correspondence table is created. This circuit component / holding unit correspondence table is a table showing which circuit component is supplied from which position of the feeder holding unit 100.

Procedure (8): Creation of Circuit Component / Part Remaining Number Correspondence Table Each SFU controller 530 transmits the contents of the circuit component / holding unit correspondence table created in procedure (7) to the M / C controller 516, respectively. The M / C controller 516 uses the contents of the received two circuit component / holding unit correspondence tables (see FIG. 17) and the contents shown in FIG. 13 stored in the circuit component database of the host computer 504. FIG. 18 shows an example of the circuit component / remaining component number correspondence table created for each carriage 52. The content of the circuit component database (see FIG. 13) is acquired via the host network 510. At this time, not all the contents of the circuit component database are acquired, but only the data of the circuit component corresponding to the component identification code included in the two circuit component / holding unit correspondence tables received from each SFU controller 530 is acquired. Thus, the time required for communication is shortened, and the circuit component / part remaining number correspondence table is efficiently created. Note that if the storage capacity of the M / C controller 516 is sufficient, the M / C controller 516 may acquire all the contents of the circuit component database in advance.

  Here, the M / C controller 516 displays all the circuit components to be mounted and the position of the feeder holding unit 100 where the feeder 54 that supplies each circuit component is held, in this circuit component / remaining component number correspondence table. And the contents of the cart / union device correspondence table shown in FIG. 15 can be obtained. It is also possible to know the values of the component storage position and the remaining number of components. Based on these contents, the mounting machine 18 is controlled. The suction position of the circuit component by the suction nozzle 20 can be controlled by considering the component storage position indicating the position of each circuit component in the component storage tape 156. Furthermore, the M / C controller 516 transmits the two circuit component / component remaining number correspondence tables created for each carriage 52 to the corresponding SFU controller 530. In the SFU controller 530, the value of the component remaining number in the circuit component / remaining component number correspondence table is changed during the mounting operation as will be described later.

Step (9): Teaching of component accommodation pitch / remaining number of components Each feeder 54 is provided with several operation switches as described above, and each time one circuit component is supplied by operating some of the switches. The rotation angle (corresponding to the component accommodation pitch) of the motors 202 and 226 can be input, and the F / D controller 540 can control the motors 202 and 226 based on the input information. In other words, the F / D controller 540 can independently control the feeder 54, but in addition, information such as the component accommodation pitch can be taught from the SFU controller 530, and any user can Can be used arbitrarily. When the latter is used, each SFU controller 530 is provided based on the contents of the circuit component / remaining component number correspondence table transmitted from the M / C controller 516 in step (8). Each of the feeders 54 held by the carriage 52 is taught with a corresponding component accommodation pitch and the number of remaining components. The F / D controller 540 of each feeder 54 stores the contents as a pitch / remaining number table shown in FIG. Therefore, the F / D controller 540 performs processing such as determination of the feed amount (rotation angle of the motors 202 and 226) of the component storage tape 156 based on the component storage pitch and self-monitoring of the remaining number of components. This can be done based on information transmitted from. In the present embodiment, when the contents of the circuit component / remaining component number correspondence table transmitted from the M / C controller 516 are stored in the F / D controller 540, the information in the table is input by operating the operation switch. It takes precedence over the information that has been made.

The component remaining number in the component remaining number table is decreased by one by the F / D controller 540 every time one circuit component is supplied. The number of remaining parts is, for example, two sets of 7-segment LED displays, LCD displays, etc. provided in each feeder 54, and the remaining number of parts stored in each part storage tape 156 in the F / D controller 540. Each feeder 54 is provided with a mechanical counter display that can be displayed or controlled by the F / D controller 540, an LCD display with low power consumption, a storage battery, and the like so that power is not supplied to the feeder 54. It is possible to display and use the remaining number of components of the component storage tape 156 attached to the device. Further, if the storage means for storing the circuit component / remaining component number correspondence table of the F / D controller 540 is a non-volatile memory such as E ² PROM, the feeder 54 from the cart 52 or the cart 52 from the component mounting device 10 is used. It is also possible to use by removing the remaining number of circuit components accommodated in each feeder 54 with the LT computer 502 or the like and displaying it on a display device in a state where it is removed from the feeder.

  When all the processes of the above procedure are completed, the preparation process is completed. The procedures (6) to (9) are preferably created after all the feeders 54 are held by the carriage 52 and the two carriages 52 are combined with the circuit component mounting apparatus 10. This is because each table shown in FIGS. 14 to 19 can be created only once. However, this is not an indispensable matter, and when the update of these tables is required, the processing from the above procedure (6) to procedure (9) may be repeated.

  As described above, in the circuit component mounting system 500 of the present embodiment, the above-described carriage / merging device correspondence table and feeder / holding unit correspondence table are created after the mounting / holding / merging operation. By comparing with the position / part identification code correspondence relationship, it is possible to grasp whether or not there is an error in the mounting and holding uniting operation. If there is an error, the fact that there was an error and the content of the error are displayed on a display (not shown) provided in the circuit component mounting apparatus 10 and reported to the operator. This display can be performed on a display provided in the host computer 504 or the carriage 52. In this way, it is possible to prompt correction of an error in the mounting / holding uniting operation. Note that, based on the content of the error, the control program itself can be corrected as if the mounting / holding / merging operation by the operator was performed correctly. That is, the supply position / part identification code correspondence relationship is corrected based on the contents of the cart / union device correspondence table and feeder / holding unit correspondence table, and includes information on the corrected supply position / part identification code correspondence relationship. Thus, the control program is rewritten. This rewriting can be performed completely automatically, or only when the operator operates the rewriting command operation member in response to an error in the mounting / holding uniting operation being displayed on the display. It is also possible to do so. In any case, even if no error correction work is performed by the operator, there is no problem in the mounting work. In addition to this case, it is only necessary that the circuit components to be mounted on the printed circuit board can be supplied. Is optional.

  This means that the circuit component mounting apparatus receives the circuit components from the circuit component supply apparatus 8 one by one as the suction nozzle 20 is moved by the XY moving device 24 as in the circuit component mounting apparatus 8 in the present embodiment. This is particularly true when the printed circuit board 16 is mounted. The circuit component mounting device is of a type in which a plurality of component holders are swung around a common swivel axis, and each suction nozzle receives a circuit component from a component supply device at a fixed component receiving position set on the swivel trajectory. (The apparatus described in Japanese Patent Laid-Open No. 7-15179 is an example thereof). This is also true to some extent in the case of other types of circuit component mounting apparatuses. Usually, the feeder mounting position is determined so as to minimize the moving distance of the feeder holding member required for supplying the circuit components. Therefore, if the feeder is not mounted at a predetermined position, the component supply is performed. It takes a long time to complete. Therefore, when the extension of this time is too large, it is desirable to change the mounting position of the feeder 54.

Next, information exchange associated with the mounting operation will be described. The M / C controller 516 stores the aforementioned control program. The control program includes an instruction for causing the M / C controller 516 to perform a circuit component mounting operation based on the supply position / component identification code correspondence relationship.
First, (i) the M / C controller 516 controls the mounting machine 18 to suck the circuit component to be mounted on the suction nozzle 20, and issues a supply command to the feeder 54 that supplies the suctioned circuit component. To emit. This command includes a component identification code of the component storage reel 150 that stores the sucked circuit component. This is because two component receiving reels can be mounted on one feeder 54, and therefore it is necessary to specify which of them is supplied with circuit components. (ii) The F / D controller 540 that has received the command sends the component storage tape 156 by either one of the driving device 200 and the driving device 201 based on the received component identification code, and sucks the next circuit component. Prepare for. (iii) The F / D controller 540
The SFU controller 530 is notified that a circuit component has been supplied with a component identification code of a component storage reel that stores the circuit component. (iv) Based on the report from each F / D controller 540, the SFU controller 530 updates the value of the component remaining number in the circuit component / component remaining number correspondence table stored by itself.

  In this way, during the mounting operation, each SFU controller 530 can always grasp the remaining number of circuit components in the feeder 54 held in the carriage 52 including itself. The contents of the circuit component / remaining component number table stored in the SFU controller 530 of each of the two carriages 52 are transmitted to the LT computer 502 by the SFU controller 530 via the interfaces 600 and 602 (and a router (not shown)). Can be sent at any time. Based on the received content, the LT computer 502 can display the status regarding the circuit components during the mounting operation on a display (not shown) to notify the operator.

On the other hand, each SFU controller 530 can transmit the contents of the circuit component / remaining component number table to the M / C controller 516 at any time via the M / C network 520. Further, the M / C controller 516 can transmit the contents to the host computer 504 via the host network 510. Based on the received content, the host computer 504 can reflect the remaining number of components on the component receiving reel 150 during the mounting operation in the circuit component database as needed. Furthermore, if a plurality of circuit component mounting apparatuses 10 are connected to the host network 510, the host computer 504 can grasp the remaining number of circuit components mounted by the plurality of circuit component mounting apparatuses 10 at any time. The contents of the circuit component database can be updated based on the remaining component number. The carriage 52, the circuit component mounting apparatus 10, and the host computer 504 can display each information obtained based on the communication described above on a display (not shown) provided on them.

  As apparent from the above description, in this embodiment, the LT computer 502, the host computer 504, the host network 510, the M / C controller 516, the M / C network 520, the SPID network 522, the SFU controller 530, and the SFU network 534 are used. , FPID network 536, F / D controller 540, etc. constitute a supply management device. The SFU controller 530, the SFU network 534, the FPID network 536, the F / D controller 540, and the like constitute feeder holding unit specifying means, and among these, the specific control is performed by the SFU controller 530, the F / D controller 540, and the like. Means are configured. Further, the SFU controller 530 constitutes a circuit component determination unit.

  In this circuit component mounting system 200, each feeder 54 has a FID that is a unique feeder identification code. Therefore, the FID and a component identification code unique to the component housing reel 150 that houses each circuit component are preliminarily stored. It is easy to associate. In other words, the circuit component / feeder correspondence table shown in FIG. 14 is simply obtained by using a barcode reader to successively connect the feeder barcode seal 572 and the component barcode seal 506 attached to each feeder 54 and the component receiving reel 150. It can be created with a simple procedure that only requires reading. Based on the contents of the circuit component / feeder correspondence table, the supply management of the circuit components is performed as described above.

If each feeder 54 has a unique FID as a feeder identification code, it is possible to perform management including not only feeders used for mounting work but also feeders not used for mounting work. . For example, it becomes easy to create a production plan. (i) Correspondence between feeder identification code of feeder used for mounting work and part identification code of mounted component storage reel, (ii) Feeder waiting with component storage reel mounted (Iii) Feeder identification code group of feeders waiting in a state in which the component receiving reel is not attached, (iv) The feeder identification code attached to the feeder A component identification code group of a component storage reel that is not installed, (v) a feeder identification code of a feeder that is waiting without a component storage reel mounted, and a component identification code of a component storage reel that can be mounted on each feeder Correspondence, (vi) (i) to (iv)
If a production plan is created based on various information regarding the state of each feeder or component storage reel, such as the position of each feeder or component storage reel in the factory, the creation becomes easy. For example, if there is a feeder that already has a component storage reel that contains the circuit components required for the next printed circuit board mounting operation, it is necessary to store the feeder or to install the next printed circuit board. There is no feeder that has a component storage reel that stores various circuit components, but it is possible to use information such as the presence or absence of a feeder that can be equipped with such a component storage reel and its storage location. is there. On the other hand, when each feeder does not have a feeder identification code, it is not possible to specify a feeder that is on standby without mounting a component accommodating reel. Therefore, the correspondence between such feeders and their positions in the factory cannot be managed. According to the production plan using the feeder identification code, it is generally relatively expensive, and a large number is required for one carriage 52. However, the number of feeders 54 is smaller than the number of circuit parts that may be mounted. Can be efficiently used as a whole. In addition, when a circuit component is sequentially mounted on a plurality of different types of printed circuit boards, the setup is changed, and the number of times that the component storage reel is attached to and removed from each feeder during the setup change is minimized. It is also possible to make a production plan.

  Note that the number of SFU controllers 530 in the configuration shown in FIG. 8 can be increased from one to a plurality. Accordingly, the number of the M / C network 520, the M / S communication unit 552, the S / M communication unit 130, the SFU network 534, the FPID network 536, and the like are also increased. The increased SFU network 534, FPID network 536 and the like are connected to different feeder holding units 100, respectively. For example, two SFU controllers 530 are provided, and one SFU controller 530 is connected to a feeder 54 held by the first and second feeder holding unit groups 102, and the other SFU controller 530 is connected to a third and third SFU controller 530. The feeder 54 held by the four feeder holding unit group 102 is connected, or four SFU controllers 530 are provided, and each of the first to fourth feeder holding unit groups 102 is connected to each SFU controller 530. The feeders 54 to be held (6 each) may be connected. Since each SFU controller 530 can reduce the number of feeders 54 that are in charge of management, communication traffic on the corresponding SFU network 534 can be afforded, communication speed can be increased, and circuit components can be supplied. Leads to higher speed. This is more effective as the frequency of suction of circuit components by the suction nozzle 20 increases.

  In this embodiment, since the position of the combination of the two carriages 52 and the circuit component mounting apparatus 10 is indefinite, the combination position is identified using the SPID network 522. For example, each carriage In the case where the union possible position is uniquely determined or when the union position data is input by an operator or the like, the SPID network 522 and the union position specifying means using the SPID network 522 may be omitted. it can.

  FIG. 20 is a system diagram showing a circuit component mounting system including a circuit component supply system according to another embodiment. The circuit component mounting system 500 of the present embodiment includes the circuit component mounting device 10 and the carriage 52 as in the above-described embodiment. However, the circuit component mounting apparatus 10 of the present embodiment does not include a device corresponding to the SPID network 522, and the carriage 52 does not include a device corresponding to the FPID network 536. Although FIG. 20 does not show the LT computer 502 included in the above-described embodiment, and the interfaces 600 and 602 for connecting the LT computer 502 and the SFU network 534 are not shown. These may also be used in the form. The circuit component mounting apparatus 10 of the present embodiment includes three M / C controllers 516. FIG. 20 shows two of them. One of the three M / C controllers 516 is connected to the host network 510 and the M / C network 520 independently, and the other two are connected to the M / C network 520. The former one M / C controller 516 is referred to as a first M / C controller 516. Each of the latter two M / C controllers 516 is referred to as a second M / C controller 516.

  The first M / C controller 516 performs processing such as control of the substrate transfer device 14 and the mounting machine 18 as in the case of the M / C controller 516 of the above-described embodiment, but the two second M / C controllers The controller 516 is used exclusively for exchanging information with the two carriages 52. The two second M / C controllers 516 are connected to the two M / S communication units 552 on a one-to-one basis. However, the M / S communication unit 552 in the present embodiment may not include the light receiving element 290. Each carriage 52 includes 24 SFU controllers 530, which are connected to the SFU network 534. Each of the 24 SFU controllers 530 is connected to the 24 S / F communication units 116 on a one-to-one basis. Note that the S / F communication unit 116 in this embodiment may not include the light receiving element 290. Further, although the SFU network 534 includes the S / M communication unit 130, the S / M communication unit 130 may not include the light emitting element 280 in the present embodiment. Each of the feeders 54 includes an F / D controller 540 connected to the F / S communication unit 270. However, the F / S communication unit 270 of the present embodiment does not include the light emitting element 280. Good.

  The three M / C controllers 516, 24 SFU controllers 530 and each F / D controller 540 each include unique address data (MID, SID and FID), as in the above-described embodiment. Furthermore, in the present embodiment, the positions of the three M / C controllers 516 in the circuit component mounting apparatus 10 are determined. Further, the positions of the 24 SFU controllers 530 in the carriage 52 are determined. By storing these positional relationships (information indicating where each SFU controller 530 having each SID as a node ID is provided) in the first M / C controller 516 in advance, The position where the feeder 54 to which the target circuit component is supplied is held can be specified by the first M / C controller 516 that controls the mounting. That is, instead of omitting the location specifying means by the SPID network 522 and the FPID network 536 in the above-described embodiment, the number of the M / C controllers 516 and the SFU controllers 530 is increased, and the location based on the node IDs is increased. It has a specific means. Therefore, although the circuit component mounting apparatus 10 and the carriage 52 are likely to be complicated in configuration, the procedure for specifying the position of the feeder 54 to which the target circuit component is supplied can be simplified. There is.

The circuit component mounting system 500 of the embodiment shown in FIG. 8 uses the SPID network 522 and the FPID network 536, and the circuit component mounting system 500 of the embodiment shown in FIG. Instead of using the FPID network 536, by increasing the number of M / C controllers 516 and SFU controllers 530, the combined position of the circuit component mounting apparatus 10 and each carriage 52 and the holding position of the feeder 54 in the carriage 52 can be changed. It was specified. This can also be implemented in yet another form whose system diagram is shown in FIG.
In FIG. 21, reference numeral 610 denotes a sign indicating a Carla code as a mark unique to the two uniting apparatuses of the circuit component mounting apparatus 10. The Carla code 610 is read by a Carla code reader 612 as a sign identifying means provided on the carriage 52 in a state where the circuit component mounting apparatus 10 and the carriage 52 are combined. The carla code reader 612 is connected to the SFU controller 530. Eventually, each SFU controller 530 can know which of the two coalescing devices the carriage 52 including itself is united based on the contents of the Carla code 610.
Further, the Carla code 610 is also provided in each of the plurality of feeder holding units 100 of each circuit component supply apparatus 10. These color codes 610 are read by a color code reader 612 provided in the feeder 54. Thereby, each F / D controller 540 can specify the position of the feeder holding unit 100 where the feeder 54 including itself is held.

  According to the above configuration, each SFU controller 530 and each F / D controller 540 can grasp its own position. Each controller notifies the M / C controller 516 of the position of the controller, so that the M / C controller 516 can specify the position of the target feeder 54. In this embodiment, the Carla code 610 is used as a sign, but other signs such as a bar code and an ID chip may be used.

In each of the embodiments described above, there is one circuit component mounting apparatus 10 and two carts 52 included in the circuit component mounting system 500, but these numbers are arbitrary. Also,
The number of feeders 54 held by each carriage 52 is also arbitrary.
Although several embodiments of the present invention have been described above, the present invention has various modifications and improvements based on the knowledge of those skilled in the art without departing from the scope of the claims. Can be implemented.
