Description

Component supply system and component mounting system

The present invention relates to a component supply system that supplies components to a component mounting machine, and a component mounting system equipped with the same.

The component mounting system comprises a component mounter having a suction nozzle that mounts components on a substrate such as a printed circuit board, and a component supply system that supplies the components that are picked up by the suction nozzle in the component mounter. The component supply system comprises a component storage device such as a reel to which a component storage member such as a component storage tape that stores a plurality of components is attached, and a feeder to which the component storage device is attached. In the component supply system, the feeder supplies the components stored in the component storage member attached to the component storage device.

In the component supply system, when a feeder becomes used due to a shortage of components in the component storage member of the component storage device attached to the feeder, the feeder is collected from the component mounting machine, and a new feeder is supplied to the component mounting machine in response to the collection. When supplying a new feeder to the component mounting machine, a setup operation is performed in which the component storage device, to which the component storage member that stores the parts to be supplied is attached, is attached to the feeder (see, for example, Patent Document 1).

The specifications of a part storage member, such as width, size of the multiple part storage sections that store parts, and spacing between the multiple part storage sections, are regulated according to the type of parts to be stored. In order for a feeder to accurately supply parts stored in a part storage member, the structure of the part supply area in the feeder that supplies parts must be designed according to the specifications of the part storage member. For this reason, a part supply system uses multiple feeders with different part supply area structures for each part storage member specification. In this case, when attaching a part storage device to which a part storage member that stores parts for supply is attached to a feeder, it is necessary to select a feeder from the multiple feeders that has a part supply area structure that matches the specifications of the part storage member.

Selecting a feeder according to the specifications of the part storage member attached to the part storage device affects the ability of the feeder to supply parts stored in the part storage member. Patent Document 1 does not disclose technology for selecting a feeder that can accurately supply parts stored in the part storage member of the part storage device from among multiple feeders with different structures in the part supply area, and there is room for improvement in this regard.

International Publication No. 2021/144863

Below, a component supply system and a component mounting system according to an embodiment of the present invention will be described with reference to the drawings.

The component mounting system 1 shown in FIG. 1 is a system for producing component-mounted boards in which components such as electronic components are mounted on a substrate such as a printed circuit board. The component mounting system 1 includes a production system 2 for producing the component-mounted boards, and a component supply system 3 for supplying components used in the production of the component-mounted boards.

[About the production system]
The production system 2 includes a plurality of mounting lines 2A including component mounters 2B, an exchange device 2C, and a production management device 2D.

<About the mounting line>
Each of the multiple mounting lines 2A is installed in a predetermined production area AR1 and includes multiple component mounters 2B arranged along the board transport direction. The multiple mounting lines 2A are installed in the production area AR1 so as to be aligned at predetermined intervals from each other in a direction intersecting the board transport direction. Fig. 1 shows an example in which three mounting lines 2A are installed side by side in a direction intersecting the board transport direction. Note that the number of mounting lines 2A and the installation positions of the mounting lines 2A within the production area AR1 are not particularly limited.

The component mounters 2B on the multiple mounting lines 2A will be described with reference to FIG. 2. In the following, directional relationships will be described using XYZ orthogonal coordinate axes. The X-axis and Y-axis directions are mutually orthogonal on a horizontal plane, and the Z-axis direction is a direction that extends vertically and is orthogonal to both the X-axis and Y-axis directions. The transport direction of the board between each component mounter 2B on the mounting line 2A coincides with the Y-axis direction.

The component mounter 2B is a device that mounts components on a board to produce a component-mounted board. Before the component mounter 2B mounts the components, a solder paste pattern is printed on the board. The component mounter 2B comprises a mounter main body 21, a transport conveyor 22, a component supply unit 23, and a head unit 26.

The mounting machine main body 21 is a housing having an internal space in which the various parts that make up the component mounter 2B are arranged. The transport conveyor 22 extends in the Y-axis direction and is arranged in an approximate central region inside the mounting machine main body 21. The transport conveyor 22 transports the board in the Y-axis direction.

The head unit 26 mounts components on the board transported by the transport conveyor 22. The head unit 26 takes out components from the multiple feeders 25 attached to the component supply unit 23, and mounts the taken out components on the board. The head unit 26 has multiple suction nozzles 261. The suction nozzle 261 is a holder capable of suctioning and holding components. The suction nozzle 261 can be connected to either a negative pressure generator, a positive pressure generator, or the atmosphere via an electric switching valve. In other words, the suction nozzle 261 can suction and hold a component by supplying negative pressure to the suction nozzle 261, and then the suction and holding of the component is released by supplying positive pressure. In the head unit 26, the multiple suction nozzles 261 pick up components supplied by the multiple feeders 25, and mount the components on the board.

The component supply unit 23 is disposed in the end region in the X-axis direction of the mounting machine main body 21. The component supply unit 23 has an upper frame 231, a lower frame 232, and a rear frame 233 for forming a plurality of supply support parts 24 that support the feeder 25 that supplies components in an insertable and removable manner. The upper frame 231 is a plate-shaped frame extending in the X-axis direction and the Y-axis direction. The upper frame 231 is disposed at one end of the mounting machine main body 21 in the X-axis direction so that a region portion on one end side in the X-axis direction is exposed to the outside from the mounting machine main body 21 and a region portion on the other end side in the X-axis direction is accommodated inside the mounting machine main body 21. The lower frame 232 is a plate-shaped frame extending in the X-axis direction and the Y-axis direction, and is disposed facing the upper frame 231 on the lower side in the Z-axis direction. The lower frame 232 has a protrusion 2321 protruding upward in the Z-axis direction in the region portion on the other end side in the X-axis direction that is accommodated inside the mounting machine main body 21. The rear frame 233 is a plate-shaped frame that extends in the Y-axis and Z-axis directions, and is positioned inside the mounting machine body 21 closer to the center of the mounting machine body 21 than the other ends of the upper frame 231 and the lower frame 232 in the X-axis direction.

The multiple supply support parts 24 support the feeders 25 in the component supply unit 23 so that they can be inserted and removed. In the component supply unit 23, the multiple supply support parts 24 are arranged so that they are aligned in the Y-axis direction. The feeders 25 are inserted and attached to each of these supply support parts 24, so that the multiple feeders 25 are aligned in the Y-axis direction.

Feeder 25 is a component supplying tool that supplies components. As long as feeder 25 is configured to be able to supply components, there are no particular limitations on the component supplying method. As feeder 25, for example, a tape feeder that supplies components using a tape as a carrier, or a stick feeder that supplies components stored in a cylindrical stick by pushing them out of the stick, etc., can be used.

Below, we will explain the case where a tape feeder is used as the feeder 25. The feeder 25 supplies components by feeding out a component storage tape PT0 as a component storage member capable of storing multiple components. The component storage tape PT0 is composed of a carrier tape PT1 provided with multiple component storage sections for storing components, and a cover tape PT2 joined to the carrier tape PT1 so as to cover the component storage sections. The feeder 25 includes a feeder body 251, an attachment section 252, a tape feeding section 254, and a recovery section 255.

The feeder body 251 is formed with a tape feed path 253. The tape feed path 253 is a path along which the component storage tape PT0 is fed, and has a component supply area 2531 between the upstream end and downstream end of the feed direction of the component storage tape PT0. The attachment section 252 is disposed on the upstream end side of the tape feed path 253 in the feeder body 251. The attachment section 252 is a portion of the feeder body 251 to which the component storage device 25A to which the component storage tape PT0 is attached is detachably attached. The component storage device 25A is, for example, a reel member attached by winding the component storage tape PT0. In the feeder 25, the component supply area 2531 is an area for supplying components stored in the component storage tape PT0 attached to the component storage device 25A attached to the attachment section 252.

The tape feeding section 254 is formed of, for example, a sprocket, and is arranged near the component supply area 2531 in the feeder body 251. The tape feeding section 254 feeds out the component storage tape PT0 from the component storage device 25A attached to the attachment section 252, and feeds out the fed component storage tape PT0 along the tape feeding path 253. The operation of the tape feeding section 254 is controlled by a control circuit mounted on the control board 259. In the component storage tape PT0 fed out along the tape feeding path 253, the cover tape PT2 is peeled off from the carrier tape PT1 upstream of the component supply area 2531. This exposes the components on the carrier tape PT1 in the component supply area 2531. The components exposed on the carrier tape PT1 can be picked up by the suction nozzle 261 of the head unit 26. In other words, the suction nozzle 261 of the head unit 26 picks up the components supplied by the feeder 25 from the component supply area 2531.

The cover tape PT2 peeled off from the carrier tape PT1 upstream of the component supply area 2531 is collected by the collection unit 255. The collection unit 255 is, for example, configured with a pair of rollers that come into contact with each other. In this case, the collection unit 255 collects the cover tape PT2 in accordance with the rotation of the pair of rollers. The cover tape PT2 collected by the collection unit 255 is stored in a collection box 2551.

After the components are picked up by the suction nozzle 261 of the head unit 26, the carrier tape PT1 is sent out from the feeder 25 via the downstream end of the tape sending path 253 by the sending operation of the tape sending section 254. The carrier tape PT1 sent out from the feeder 25 is cut to a predetermined length by the tape cutter 23A arranged near the protrusion 2321 of the lower frame 232 of the component supply unit 23.

2, the feeder 25 has an upper positioning pin 256, a lower positioning pin 257, and a feeder side connector 258. The upper positioning pin 256 and the lower positioning pin 257 are pins provided so as to protrude from one end of the feeder body 251 in the X-axis direction. The upper positioning pin 256 and the lower positioning pin 257 are arranged at an interval from each other in the Z-axis direction at one end of the feeder body 251 in the X-axis direction, and the upper positioning pin 256 is located above the lower positioning pin 257. One end of the feeder body 251 in the X-axis direction has a stepped portion recessed on the other side in the X-axis direction from the portion where the upper positioning pin 256 and the lower positioning pin 257 are provided. A feeder side connector 258 is provided at the stepped portion at one end of the feeder body 251 in the X-axis direction. The feeder side connector 258 is a connector that is electrically connected to the control board 259.

The multiple supply support parts 24 for supporting the feeders 25 so that they can be inserted and removed are formed on the upper frame 231, the lower frame 232, and the rear frame 233 of the component supply unit 23. Each supply support part 24 includes an upper holding rail 241, a lower holding rail 242, an upper pin insertion hole 243, a lower pin insertion hole 244, and a unit side connector 245.

The upper holding rails 241 are formed in a number of rows in the Y-axis direction so as to extend in the X-axis direction on the underside of the upper frame 231. The upper holding rails 241 are rail members that guide the upper end of the feeder 25 when it moves when the feeder 25 is inserted into or removed from the supply support section 24. The lower holding rails 242 are formed in a number of rows in the Y-axis direction so as to extend in the X-axis direction on the upper side of the lower frame 232. The lower holding rails 242 are rail members that guide the lower end of the feeder 25 when it moves when the feeder 25 is inserted into or removed from the supply support section 24.

The upper pin insertion holes 243 are holes formed in a line in the Y-axis direction at the upper end of the rear frame 233. The upper pin insertion holes 243 allow the upper positioning pins 256 of the feeder 25 to pass through when the feeder 25 is inserted into the supply support section 24. On the other hand, when the feeder 25 is removed from the supply support section 24, the upper positioning pins 256 are released from passing through the upper pin insertion holes 243. The lower pin insertion holes 244 are holes formed in a line in the Y-axis direction at the lower end of the rear frame 233. The lower pin insertion holes 244 allow the lower positioning pins 257 of the feeder 25 to pass through when the feeder 25 is inserted into the supply support section 24. On the other hand, when the feeder 25 is removed from the supply support section 24, the lower positioning pins 257 are released from passing through the lower pin insertion holes 244. The feeder 25 is positioned relative to the supply support section 24 by inserting the upper positioning pin 256 into the upper pin insertion hole 243 and the lower positioning pin 257 into the lower pin insertion hole 244.

The unit side connectors 245 are arranged in a line in the Y-axis direction on the protrusion 2321 of the lower frame 232, and are electrically connected to the control unit of the component mounter 2B. The unit side connectors 245 are connected to the feeder side connectors 258 of the feeder 25 when the feeder 25 is inserted into the supply support unit 24.

The feeder 25 supported by the supply support part 24 of the component supply unit 23 in the component mounter 2B and the component storage device 25A attached to the feeder 25 are provided in the component supply system 3 described below. Details will be described later, but the component supply system 3 further includes a storage device 5 installed in the first preparation area AR2 adjacent to the production area AR1, and a component storehouse 4 installed in the second preparation area AR3 adjacent to the first preparation area AR2, as shown in FIG. 1. The component storehouse 4 is a warehouse that stores the component storage device 25A. The storage device 5 is a device having a storage unit 51 that stores the feeder 25, and includes a recovery storage device 5A and a replenishment storage device 5B. The storage unit 51 of the recovery storage device 5A stores the feeder 25 that has been recovered from the component supply unit 23 of the component mounter 2B and has become used due to a shortage of components or the like in the component storage tape PT0 of the component storage device 25A. Meanwhile, the storage unit 51 of the supply storage device 5B stores the feeders 25 to be replenished to the component supply unit 23 in response to the collection of used feeders 25.

<About the exchange device>
1, the exchange device 2C is a robot that can move within the production area AR1 to each position facing the component supply unit 23 of each mounter 2B in the multiple mounting lines 2A and the storage unit 51 of the storage device 5. The exchange device 2C performs the task of exchanging the feeder 25 between the component supply unit 23 of the mounter 2B and the storage unit 51 of the storage device 5.

The replacement device 2C includes a replacement unit 2C1 and an operation unit 2C2. The replacement unit 2C1 is a unit that supports multiple feeders 25 to be collected from the component supply unit 23 of the component mounter 2B and multiple feeders 25 to be replenished to the component supply unit 23. In other words, the replacement unit 2C1 is a unit that supports multiple feeders 25 to be exchanged between the component supply unit 23 and the replacement unit 2C1. The operation unit 2C2 is a unit that performs the operation of moving the feeders 25 relative to the replacement unit 2C1.

In the replacement device 2C, when the replacement unit 2C1 is placed in a position facing the storage unit 51 of the replenishment storage device 5B, the operation unit 2C2 performs the work of extracting the feeder 25 to be replenished to the part supply unit 23 from the storage unit 51 and taking it into the replacement unit 2C1. Also, when the replacement unit 2C1 is placed in a position facing the part supply unit 23, the operation unit 2C2 performs the work of extracting the feeder 25 to be retrieved from the part supply unit 23 and retrieving it to the replacement unit 2C1, and also performs the work of replenishing the feeder 25 to be replenished on the replacement unit 2C1 to the part supply unit 23. Also, when the replacement unit 2C1 is placed in a position facing the storage unit 51 of the recovery storage device 5A, the operation unit 2C2 performs the work of moving the feeder 25 to be retrieved that is retrieved on the replacement unit 2C1 to the storage unit 51. As a result, the feeder 25 to be retrieved that is retrieved from the part supply unit 23 is stored in the storage unit 51 of the recovery storage device 5A.

<Production control device>
The production management device 2D is configured by a microcomputer equipped with a CPU (Central Processing Unit) as a processing unit that performs various calculation processes. The production management device 2D is connected to each of the component mounters 2B in the multiple mounting lines 2A and the exchange device 2C so as to be able to perform data communication. The production management device 2D is a device that manages the production of component mounting boards by the component mounters 2B. When managing the production of component mounting boards by the component mounters 2B, the production management device 2D also manages the collection of feeders 25 to be collected from the component supply unit 23 by the exchange device 2C and the replenishment of feeders 25 to be replenished to the component supply unit 23 by the exchange device 2C.

The production management device 2D outputs production instruction data DB1 to the component mounter 2B, thereby controlling the component supply operation of each feeder 25 supported by each supply support part 24 of the component supply unit 23, and the component suction operation and component mounting operation of each suction nozzle 261 of the head unit 26. In this way, the production management device 2D causes the component mounter 2B to produce component-mounted boards.

The production management device 2D acquires production performance data DPT from each component mounter 2B, which indicates the current production performance of component mounting boards by each component mounter 2B. As shown in FIG. 3, the production performance data DPT is data including, for example, feeder identification information FID, component name information PID1, component storage device identification information RID, supply support part position information SSP, normal pickup rate FFR, and component out-of-stock index value PNV.

The feeder identification information FID is information for identifying each of the multiple feeders 25 attached to the component supply unit 23. Details of this feeder identification information FID will be described later. The component storage device identification information RID is information for identifying the component storage device 25A attached to the feeder 25 indicated by the feeder identification information FID. The component name information PID1 is information indicating the component name for identifying the component stored in the component storage tape PT0 attached to the component storage device 25A indicated by the component storage device identification information RID. The supply support part position information SSP is information indicating the position of each supply support part 24 that supports each feeder 25 in the component supply unit 23 of each component mounter 2B.

The normal pickup rate FFR is information on the normal pickup rate indicating the proportion of parts that are normally picked up by the suction nozzles 261 for each of the feeders 25 supported by each supply support part 24 of the component supply unit 23. Specifically, the normal pickup rate FFR indicates the proportion of the number of times that each of the feeders 25 was used in a situation where the suction nozzles 261 were normally picking up parts, relative to the total number of times that each of the feeders 25 was used in a specified period. When viewed for each of the feeders 25, the higher the normal pickup rate FFR, the more times the suction nozzles 261 were used in a situation where the suction nozzles 261 were normally picking up parts. For this reason, among the feeders 25, a feeder 25 with a low normal pickup rate FFR may be a cause of poor component pickup by the suction nozzles 261. A poor component pickup by the suction nozzles 261 means a poor component pickup by the suction nozzles 261, such as a pickup error or a misaligned pickup position.

The component shortage index value PNV indicates a value that serves as an index for predicting component shortages for each of the multiple feeders 25 supported by each supply support part 24 of the component supply unit 23. The component shortage index value PNV is expressed, for example, as the remaining number of components on the component storage tape PT0 of the component storage device 25A attached to each of the multiple feeders 25. As the component shortage index value PNV increases for the multiple feeders 25, the time until component shortage occurs on the component storage tape PT0 of the component storage device 25A becomes longer.

The production management device 2D predicts a shortage of parts in the part storage tape PT0 of the part storage device 25A for the multiple feeders 25 supported by each supply support part 24 of the part supply unit 23 based on the part shortage index value PNV included in the production performance data DPT. The production management device 2D then identifies the feeder 25 corresponding to the part storage device 25A to which the part storage tape PT0 predicted to be out of parts is attached as the feeder 25 to be collected from the part supply unit 23. When the feeder 25 to be collected is identified, the production management device 2D recognizes the feeder 25 to be replenished to the part supply unit 23 in response to the collection of the feeder 25 to be collected.

When the feeder 25 to be collected is identified and the feeder 25 to be replenished is recognized, the production management device 2D outputs exchange instruction data DC1 to the replacement device 2C. The exchange instruction data DC1 is data indicating an instruction to replace the feeder 25, which supplies the feeder 25 to be replenished to the part supply unit 23 in response to the collection of the feeder 25 to be collected. The replacement device 2C collects the feeder 25 to be collected from the part supply unit 23 to the replacement unit 2C1 based on the exchange instruction data DC1, and supplies the feeder 25 to be replenished from the replacement unit 2C1 to the part supply unit 23 in response to the collection. The replacement device 2C moves the feeder 25 to be collected that has been collected on the replacement unit 2C1 to the storage unit 51 of the collection storage device 5A. As a result, the feeder 25 to be collected that has been collected from the part supply unit 23 is stored in the storage unit 51 of the collection storage device 5A.

[About the parts supply system]
The component supply system 3 is a system for supplying components to be sucked by the suction nozzle 261 of the head unit 26 in the component mounter 2B. The component supply system 3 includes the above-mentioned multiple feeders 25 attached to the component supply unit 23 of the component mounter 2B, and the above-mentioned component storage devices 25A attached to each feeder 25. Furthermore, as shown in FIG. 1 , the component supply system 3 includes a component warehouse 4, storage devices 5 including a recovery storage device 5A and a replenishment storage device 5B, a workbench 6, and a component supply management device 7.

<Feeders and parts storage devices>
When component mounter 2B produces component-mounted boards, multiple types of components are mounted on each board. Furthermore, different types of components are mounted on different types of boards. The component storage tape PT0 attached to component storage device 25A has specifications, such as width, size of the multiple component storage sections that store components, and spacing between the multiple component storage sections, that are defined according to the types of components to be stored. Component storage device 25A to which component storage tape PT0 with specifications defined according to the types of components to be stored is attached is stored in component warehouse 4 located in second preparation area AR3, as described above.

As shown in FIG. 4, a first storage item recording unit 25R1 and a second storage item recording unit 25R2 are attached to the component storage item 25A. The first storage item recording unit 25R1 records component information PID for identifying the type of component stored in the component storage tape PT0. The first storage item recording unit 25R1 is, for example, a barcode in which the component information PID has been coded and recorded. The second storage item recording unit 25R2 records component storage item identification information RID for identifying the component storage item 25A. The second storage item recording unit 25R2 is, for example, a barcode in which the component storage item identification information RID has been coded and recorded.

In order for the feeder 25 equipped with the component storage device 25A to accurately supply the components stored on the component storage tape PT0, the structure of the component supply area 2531, which is the area where the components are supplied, needs to be designed to correspond to the specifications of the component storage tape PT0 according to the type of component. For this reason, the component supply system 3 uses multiple feeders 25 with different structures of the component supply area 2531 for each specification of the component storage tape PT0 in the component storage device 25A attached to the attachment section 252.

As shown in FIG. 4, a feeder recording unit 25R3 is attached to each of the multiple feeders 25. The feeder recording unit 25R3 records feeder identification information FID for identifying each of the multiple feeders 25, which is set according to the structure of the component supply area 2531. The feeder recording unit 25R3 is, for example, a barcode that records the feeder identification information FID in an encoded form.

As shown in FIG. 5, each of the component supply areas 2531 of the multiple feeders 25 has a guide member 253A, a peeling position adjustment member 253B, and a leaf spring member 253C as multiple adjustment members that can adjust the component supply.

The guide member 253A is a member that is detachably attached to the feeder body 251 in the component supply area 2531. In the component supply area 2531, the guide member 253A adjusts the supply of components stored in the component storage tape PT0 by guiding the side end surface in the width direction of the component storage tape PT0 that is sent along the tape sending path 253 by the tape sending section 254. There are multiple guide members 253A according to the tape width that defines the length in the width direction of the component storage tape PT0. In the feeder 25, it is necessary to select an appropriate guide member 253A from the multiple guide members 253A according to the tape width specifications of the component storage tape PT0 in the component storage device 25A that is attached to the attachment section 252.

The peeling position adjustment member 253B is a member that is detachably attached to the guide member 253A in the component supply area 2531. The peeling position adjustment member 253B adjusts the peeling position of the cover tape PT2 from the carrier tape PT1 of the component storage tape PT0 in the component supply area 2531, thereby adjusting the supply of components stored in the component storage tape PT0. In the feeder 25, it is necessary to adjust whether the peeling position adjustment member 253B is attached to the guide member 253A and the peeling position of the cover tape PT2 by the peeling position adjustment member 253B depending on the specifications such as the size of the multiple component storage sections of the component storage tape PT0 in the component storage device 25A attached to the attachment section 252 and the spacing between the multiple component storage sections.

The leaf spring member 253C is a member that is detachably attached to the guide member 253A in the component supply area 2531. In the component supply area 2531, the leaf spring member 253C adjusts the supply of components stored in the component storage tape PT0 by lifting the carrier tape PT1 of the component storage tape PT0 from below and regulating the movement of components within the component storage section by magnetic force or the like. In the feeder 25, it is necessary to adjust whether or not the leaf spring member 253C is attached to the guide member 253A depending on the specifications such as the size of the multiple component storage sections of the component storage tape PT0 in the component storage device 25A that is attached to the mounting section 252.

The component supply area 2531 of the feeder 25 can be reconfigured in structure according to the specifications of the component storage tape PT0 using a number of guide members 253A, peeling position adjustment members 253B, and leaf spring members 253C.

As described above, the feeder 25 to be collected that is collected from the component supply unit 23 of the component mounter 2B is stored in the storage unit 51 of the collection storage device 5A, and the feeder 25 to be replenished to the component supply unit 23 is stored in the storage unit 51 of the replenishment storage device 5B. The feeder 25 to be replenished is prepared by the worker OP or the work robot mounting the supply part storage device 25AS to the feeder 25FB to be mounted on the workbench 6 installed in the first preparation area AR2. The feeder 25FB to be mounted is a feeder 25 identified from among the multiple feeders 25 to be collected that are stored in the storage unit 51 of the collection storage device 5A in the identification process by the processing unit 71 of the component supply management device 7 described below. The supply part storage device 25AS is a part storage device 25A that is taken out from the component warehouse 4 in the preparation instruction process by the processing unit 71 of the component supply management device 7 described below.

As shown in FIG. 6, in the storage device 5 including the recovery storage device 5A and the replenishment storage device 5B, the storage unit 51 has multiple storage support parts 511a-511g. The multiple storage support parts 511a-511g support the feeders 25 so that they can be inserted and removed. The storage unit 51 stores the multiple feeders 25 while being supported by each of the storage support parts 511a-511g. The storage device 5 also has multiple notification parts 512 installed for each of the multiple storage support parts 511a-511g in the storage unit 51. The notification parts 512 include light-emitting elements such as LEDs, and notify the storage position of the feeder 25 in the storage unit 51 by emitting light, etc.

<About the parts supply management device>
The component supply management device 7 is a device that manages the multiple feeders 25 in the component supply system 3. The component supply management device 7 is configured by a microcomputer that includes a processing unit 71 consisting of a CPU that performs various types of calculation processing, and a storage unit 72 that stores various types of information and data. The component supply management device 7 is connected to each of the component mounters 2B in the multiple mounting lines 2A, the portable terminal device PT or the work robot carried by the worker OP performing work in the first preparation area AR2, the storage device 5, and the workbench 6 so as to be able to communicate data with them.

The memory unit 72 stores part-specific supply area data DZ1 shown in FIG. 7, feeder location data DZ2 shown in FIG. 8, and feeder management data DZ3 shown in FIG. 9.

The component-specific supply area data DZ1 is data that indicates, for each type of component, the structure of the component supply area section 2531 that is suitable for supplying components in the feeder 25. The component-specific supply area data DZ1 is data that associates component information PID for identifying the type of part with suitable area information CSD regarding the structure of the component supply area section 2531 that is suitable for supplying the part indicated by the part information PID. The component information PID includes component name information PID1 that indicates the name of the part, component size information PID2 that indicates the size of the part, and component storage tape information PID3 that relates to the component storage tape PT0 that stores the parts. The component storage tape information PID3 includes information on the tape width and tape type of the component storage tape PT0. The suitable area information CSD includes suitable guide member information CSD1 for identifying each of the multiple guide members 253A as information regarding the structure of the component supply area 2531 suitable for supplying the component indicated by the component information PID, suitable peeling position adjustment member information CSD2 indicating whether or not a peeling position adjustment member 253B is attached and the peeling position, and suitable leaf spring member information CSD3 indicating whether or not a leaf spring member 253C is attached.

The feeder location data DZ2 is data indicating the current location of multiple feeders 25 having different structures of the component supply area 2531 for each specification of the component storage tape PT0. The feeder location data DZ2 is data that associates feeder information FD related to the feeder 25 with location information WD related to the location of the feeder 25. The feeder information FD includes feeder type information FTD indicating the type of feeder 25, and feeder identification information FID for identifying the feeder 25 set according to the structure of the component supply area 2531. For each type of feeder 25, there are multiple feeders 25 with different structures of the component supply area 2531. For this reason, in the feeder information FD, multiple feeder identification information FID are associated with one feeder type information FTD. The feeder identification information FID is individual identification information for identifying each feeder 25, which is assigned to each feeder 25 according to the structure of the component supply area 2531.

The type of feeder 25 indicated by the feeder type information FTD is distinguished by the supply method of the component storage tape PT0 for each tape width of the component storage tape PT0 that can be used to supply components. Examples of the supply method of the component storage tape PT0 include a splicing method and an auto-loading method. In a splicing type feeder 25, when the leading component storage tape PT0, which is used to supply components, runs short, a splicing operation is performed to splice a supply component storage tape PT0 to the rear end of the leading component storage tape PT0. On the other hand, in an auto-loading type feeder 25, if the leading end of the component storage tape PT0 is set at a predetermined position, the component storage tape PT0 can be automatically loaded into the component supply area 2531 in response to a button operation. Also, if the leading end of the supply component storage tape PT0 is set at the predetermined position, the supply component storage tape PT0 is automatically loaded into the component supply area 2531 after the leading component storage tape PT0 has been completely fed out. The type of feeder 25 indicated by the feeder type information FTD can be, for example, a splicing type feeder for 8 mm width, an autoloading type feeder for 8 mm width, etc.

Feeder management data DZ3 is data indicating the current structure of the component supply area 2531 in each of the multiple feeders 25. Feeder management data DZ3 is data that associates feeder information FD, which includes feeder type information FTD and feeder identification information FID, with component supply area information PSD regarding the current structure of the component supply area 2531. The component supply area information PSD includes, as information regarding the current structure of the component supply area 2531 in the feeder 25 indicated by the feeder identification information FID, guide member information PSD1 for identifying each of the multiple guide members 253A, peeling position adjustment member information PSD2 indicating whether or not a peeling position adjustment member 253B is attached and the peeling position, and leaf spring member information PSD3 indicating whether or not a leaf spring member 253C is attached.

The processing unit 71 performs various calculation processes to manage a plurality of feeders 25 having different structures of the component supply area portion 2531 for each specification of the component storage tape PT0. The processing unit 71 performs various calculation processes before the replacement device 2C replaces the feeder 25 with the component supply unit 23 of the component mounter 2B. That is, the processing unit 71 performs various calculation processes to manage a plurality of feeders 25 before the production management device 2D outputs replacement instruction data DC1 to the replacement device 2C. By performing various calculation processes, the processing unit 71 identifies a combination of the feeder 25 and the component storage device 25A for the feeder 25 to be supplied to the component supply unit 23. As shown in the flowchart of FIG. 10, the processing unit 71 performs various calculation processes, such as a preparation instruction process S1, a supply component recognition process S2, an extraction process S3, a specification process S4, an installation instruction process S5, and an update process S6.

(Preparation Instruction Processing)
11, in the preparation instruction process S1, the processing unit 71 outputs preparation instruction data DA1 indicating an instruction to prepare a supply part storage device 25AS to a mobile terminal device PT carried by an operator OP in the first preparation area AR2 or the second preparation area AR3, or to a work robot. The supply part storage device 25AS indicates the component storage device 25A to which a component storage tape PT0 storing a supply part requested to be supplied to the component mounter 2B is attached. The preparation instruction data DA1 includes supply part information PSUD regarding the supply part, including part name information PID1 of the supply part, and component warehouse storage position information PWD indicating the position where the supply part storage device 25AS is stored in the component warehouse 4.

Based on the preparation instruction data DA1 input to the mobile terminal device PT, the worker OP removes the supply part storage device 25AS from the parts warehouse 4 and carries the removed supply part storage device 25AS to the workbench 6. This allows the worker OP to prepare the supply part storage device 25AS on the workbench 6. Note that when the preparation instruction data DA1 is input to a work robot, the work robot prepares the supply part storage device 25AS on the workbench 6.

(Supply Parts Recognition Processing)
11, the operator OP or the work robot performs a reading operation to read the first storage item recording unit 25R1 and the second storage item recording unit 25R2 attached to the supply parts storage item 25AS with a reading device 61 such as a barcode reader attached to the workbench 6. As a result, the part information PID recorded in the first storage item recording unit 25R1 and the part storage item identification information RID recorded in the second storage item recording unit 25R2 are read as information related to the supply parts storage item 25AS.

The part information PID and part storage device identification information RID for the spare part storage device 25AS read by the reading device 61 on the workbench 6 are input to the parts supply management device 7. The processing unit 71 performs a spare part recognition process S2 to recognize the spare part storage device 25AS based on the part information PID and part storage device identification information RID input to the parts supply management device 7.

(Extraction process)
In the component supply system 3, a plurality of feeders 25 having different structures of the component supply area 2531 for each specification of the component storage tape PT0 corresponding to the type of component are used as the feeders 25 for supplying components used in the production of component mounting boards in the component mounter 2B. For this reason, when a supply component storage device 25AS to which a component storage tape PT0 storing a supply component is attached is mounted in the mounting section 252 of the feeder 25, it is necessary to select from the plurality of feeders 25 a feeder 25 having a component supply area 2531 having a structure corresponding to the specification of the component storage tape PT0 corresponding to the type of supply component.

Therefore, after the supply part recognition process S2, the processing unit 71 performs the extraction process S3. As shown in FIG. 12, in the extraction process S3, the processing unit 71 extracts from the feeders 25 a number of available feeders 25FA that can be used for the supply part storage device 25AS, based on the feeder identification information FID for identifying each of the feeders 25, which is set according to the structure of the part supply area section 2531. In the example of FIG. 12, the supply part storage device 25AS is a part storage device 25A with part storage device identification information RID of "R01" to which a part storage tape PT0 is attached, which stores a supply part with a part name of "P01" indicated by part name information PID1 included in part information PID. Then, the processing unit 71 extracts the feeders 25 with feeder identification information FID of "F01" and "F02" as a number of available feeders 25FA that can be used for the supply part storage device 25AS.

The feeder identification information FID is set according to the structure of the component supply area 2531 in the feeder 25. That is, the feeder identification information FID is differentiated for each structure of the component supply area 2531. Therefore, the processing unit 71 can extract multiple usable feeders 25FA as feeders 25 having a component supply area 2531 structured to be able to supply the supply parts stored in the component storage tape PT0 of the supply part storage device 25AS, based on the feeder identification information FID differentiated for each structure of the component supply area 2531. The multiple usable feeders 25FA extracted in the extraction process S3 of the processing unit 71 have a component supply area 2531 structured to be able to supply the supply parts. Therefore, it is possible to select a feeder 25 that can accurately supply the supply parts from the multiple usable feeders 25FA.

As shown in FIG. 12, in extraction process S3, the processing unit 71 acquires the part-specific supply area data DZ1 of FIG. 7, the feeder location data DZ2 of FIG. 8, and the feeder management data DZ3 of FIG. 9 from the storage unit 72. Based on the part-specific supply area data DZ1, the processing unit 71 recognizes the suitable area information CSD corresponding to the supply part, which is associated with the part information PID related to the supply part stored in the part storage tape PT0 of the supply part storage device 25AS. Then, based on the suitable area information CSD corresponding to the supply part and the feeder identification information FID of each of the multiple feeders 25 included in the feeder location data DZ2 and the feeder information FD of the feeder management data DZ3, the processing unit 71 extracts multiple usable feeders 25FA that can be used for the supply part storage device 25AS from among the multiple feeders 25.

The suitable area information CSD corresponding to the supply part is information indicating the structure of the parts supply area section 2531 suitable for supplying the supply part. Therefore, the processing unit 71 can extract a plurality of usable feeders 25FA as feeders 25 having a parts supply area section 2531 with a structure capable of supplying the supply part, based on the suitable area information CSD corresponding to the supply part and the feeder identification information FID distinguished for each structure of the parts supply area section 2531.

Specifically, the processing unit 71 extracts, from among the multiple feeder identification information FIDs included in the feeder location data DZ2 and the feeder information FD of the feeder management data DZ3, the feeder identification information FID of interest where the guide member information PSD1 included in the part supply area information PSD of the feeder management data DZ3 matches the compatible guide member information CSD1 included in the compatible area information CSD corresponding to the supply part, and where the location information WD of the feeder location data DZ2 indicates the storage unit 51 of the recovery storage device 5A. In this case, the processing unit 71 recognizes each feeder 25 indicated by the feeder identification information FID of interest as a multiple available feeder 25FA that can be used for the supply part storage device 25AS.

(Specific Processing)
After the extraction process S3, the processing unit 71 performs the identification process S4. As shown in Fig. 12, in the identification process S4, the processing unit 71 identifies a target feeder 25FB to which a supply parts storage device 25AS is to be attached from among a plurality of available feeders 25FA. In the example of Fig. 12, the processing unit 71 identifies one feeder 25 with feeder identification information FID of "F01" from among a plurality of available feeders 25FA with feeder identification information FID of "F01" and "F02", as the target feeder 25FB.

Specifically, the processing unit 71 recognizes the conformity of the structure of the component supply area portion 2531 in the multiple available feeders 25FA to the specifications of the component storage tape PT0 in the supply component storage device 25AS based on the component supply area information PSD corresponding to the available feeders 25FA, which is associated with the feeder identification information FID of the multiple available feeders 25FA in the feeder management data DZ3.

For example, the processing unit 71 recognizes the compatibility of the structure of the component supply area 2531 in a plurality of available feeders 25FA based on the degree of match between the guide member information PSD1, peeling position adjustment member information PSD2, and leaf spring member information PSD3 included in the component supply area information PSD corresponding to the available feeder 25FA and the compatible guide member information CSD1, compatible peeling position adjustment member information CSD2, and compatible leaf spring member information CSD3 included in the compatible area information CSD corresponding to the supply part. In this case, if the information PSD1, PSD2, and PSD3 included in the component supply area information PSD corresponding to the available feeder 25FA completely matches the information CSD1, CSD2, and CSD3 included in the compatible area information CSD corresponding to the supply part, the structure of the component supply area 2531 is in a completely compatible state, being completely compatible with the specifications of the component storage tape PT0 in the supply part storage device 25AS. On the other hand, if the information PSD1, PSD2, and PSD3 contained in the part supply area information PSD corresponding to the available feeder 25FA does not completely match the information CSD1, CSD2, and CSD3 contained in the compatible area information CSD corresponding to the supply part, this means that the structure of the part supply area section 2531 is not completely compatible with the specifications of the part storage tape PT0 in the supply part storage device 25AS.

The processing unit 71 identifies the available feeder 25FA with the highest degree of compatibility as the target feeder 25FB on which the supply part storage device 25AS is to be mounted, based on the compatibility of the structure of the component supply area 2531 among the multiple available feeders 25FA. The target feeder 25FB is a feeder 25 identified based on the compatibility of the structure of the component supply area 2531 with the specifications of the component storage tape PT0 that stores the supply parts, and is therefore a feeder 25 having a component supply area 2531 with a structure that can accurately supply the supply parts.

(Wear instruction process)
After the identification process S4, the processing unit 71 performs an installation instruction process S5. As shown in Fig. 13, in the installation instruction process S5, the processing unit 71 outputs installation instruction data DA2 indicating an instruction to install the supply part storage device 25AS in the installation section 252 of the target feeder 25FB to a mobile terminal device PT carried by a worker OP in the first preparation area AR2 or the second preparation area AR3, or to a work robot. The installation instruction data DA2 includes feeder identification information FID of the target feeder 25FB and storage unit information SUD for identifying the storage unit 51 of the recovery storage device 5A that stores the target feeder 25FB.

The worker OP identifies the storage unit 51 in the recovery storage device 5A that stores the target feeder 25FB according to the storage unit information SUD included in the mounting instruction data DA2 input to the mobile terminal device PT, and removes the target feeder 25FB from the storage unit 51. This allows the worker OP to prepare the target feeder 25FB on the work bench 6 on which the supply part storage device 25AS has been prepared. When the target feeder 25FB is prepared on the work bench 6 in addition to the supply part storage device 25AS, the worker OP can perform the task of mounting the supply part storage device 25AS to the mounting portion 252 of the target feeder 25FB according to the mounting instruction data DA2. Note that when the mounting instruction data DA2 is input to a work robot, the work robot performs the task of mounting the supply part storage device 25AS to the target feeder 25FB.

Also, as shown in FIG. 13, in the attachment instruction process S5, the processing unit 71 outputs notification instruction data DA3 to the recovery storage device 5A, which indicates an instruction to notify the storage position of the attachment target feeder 25FB in the storage unit 51 of the recovery storage device 5A. In accordance with the notification instruction data DA3, the recovery storage device 5A causes the notification unit 512 corresponding to the storage support unit 511 that supports the attachment target feeder 25FB in the storage unit 51 to perform a notification operation such as emitting light. This allows the worker OP or the work robot to grasp the storage position of the attachment target feeder 25FB in the storage unit 51 based on the notification operation in accordance with the notification instruction data DA3 by the notification unit 512 of the recovery storage device 5A.

Here, the mounting instruction process S5 in the case where the processing unit 71 recognizes in the identification process S4 that the structure of the component supply area 2531 in the target feeder 25FB does not fully conform to the specifications of the component storage tape PT0 in the supply component storage device 25AS will be described with reference to FIG. 14. In this case, in the mounting instruction process S5, the processing unit 71 outputs mounting instruction data DA2 to which structure change instruction information DA21 and change confirmation information DA22 have been added.

The structure change instruction information DA21 is information indicating an instruction to change the structure of the component supply area 2531 in the target feeder 25FB by using the guide member 253A, peeling position adjustment member 253B, and leaf spring member 253C as multiple adjustment members. When the mounting instruction data DA2 to which the structure change instruction information DA21 is added is output from the processing unit 71, the worker OP or the work robot can perform the work of changing the structure of the component supply area 2531 in the target feeder 25FB according to the structure change instruction information DA21 so that the structure of the component supply area 2531 in the target feeder 25FB completely matches the specifications of the component storage tape PT0 in the supply component storage device 25AS. The worker OP or the work robot can then perform the work of mounting the supply component storage device 25AS to the target feeder 25FB in which the structure of the component supply area 2531 has been changed.

The change confirmation information DA22 is information indicating an instruction to confirm that the structure of the component supply area 2531 in the target feeder 25FB has been changed in accordance with the structure change instruction information DA21. When the mounting instruction data DA2 to which the structure change instruction information DA21 and the change confirmation information DA22 have been added is output from the processing unit 71, the worker OP or the work robot can confirm, in accordance with the change confirmation information DA22, whether or not the work to change the structure of the component supply area 2531 has been performed in accordance with the structure change instruction information DA21. This allows the worker OP or the work robot to more reliably perform the work of changing the structure of the component supply area 2531 in the target feeder 25FB.

Next, the mounting instruction process S5 in the case where the processing unit 71 recognizes in the identification process S4 that the structure of the component supply area 2531 in the target feeder 25FB is in a completely compatible state with the specifications of the component storage tape PT0 in the supply component storage device 25AS, will be described with reference to FIG. 15. In this case, in the mounting instruction process S5, the processing unit 71 acquires the production performance data DPT in FIG. 3 from the component mounter 2B (step S51). The production performance data DPT includes feeder identification information FID and component storage device identification information RID as information on the performance of the combination pattern of the component storage device 25A and the feeder 25 used to supply components to the suction nozzle 261. Furthermore, the production performance data DPT includes information on the normal suction rate FFR, which indicates the proportion of components normally picked up by the suction nozzle 261 for each of the multiple feeders 25.

When the production performance data DPT is acquired, the processing unit 71 checks the actual combination pattern of the parts storage device 25A and the feeder 25 based on the production performance data DPT (step S52). Then, the processing unit 71 determines whether or not an actual combination pattern of the supply parts storage device 25AS and the target feeder 25FB exists based on the feeder identification information FID and the parts storage device identification information RID in the production performance data DPT (step S53). If a combination of the feeder identification information FID of the target feeder 25FB and the parts storage device identification information RID of the supply parts storage device 25AS exists in the production performance data DPT, the processing unit 71 determines that an actual combination pattern of the supply parts storage device 25AS and the target feeder 25FB exists. On the other hand, if there is no combination of the feeder identification information FID of the target feeder 25FB and the part storage device identification information RID of the supply part storage device 25AS in the production performance data DPT, the processing unit 71 determines that there is no performance record of the combination pattern of the supply part storage device 25AS and the target feeder 25FB.

If there is no record of a combination pattern of the supply part storage device 25AS and the target feeder 25FB in the production history data DPT, it cannot be completely denied that the structure of the part supply area 2531 in the target feeder 25FB is not actually a perfect match. Therefore, if there is no record of a combination pattern of the supply part storage device 25AS and the target feeder 25FB (NO in step S53), the processing unit 71 outputs the mounting instruction data DA2 to which the compatibility confirmation information DA23 has been added (step S55).

The compatibility confirmation information DA23 is information indicating an instruction to confirm that the structure of the component supply area 2531 in the target feeder 25FB is fully compatible with the specifications of the component storage tape PT0 in the supply component storage device 25AS. When the mounting instruction data DA2 with the compatibility confirmation information DA23 added is output from the processing unit 71, the worker OP or the work robot can perform the work of confirming that the structure of the component supply area 2531 in the target feeder 25FB is actually fully compatible in accordance with the compatibility confirmation information DA23. In this case, the worker OP or the work robot can perform the work of mounting the supply component storage device 25AS to the target feeder 25FB for which it has been confirmed that the structure of the component supply area 2531 is fully compatible.

If the production performance data DPT contains a pattern of combinations of the supply part storage device 25AS and the target feeder 25FB (YES in step S53), the processing unit 71 determines whether the normal suction rate FFR corresponding to the combination pattern is equal to or lower than a predetermined threshold (step S54). Even if the production performance data DPT contains a pattern of combinations of the supply part storage device 25AS and the target feeder 25FB, if the normal suction rate FFR for the suction nozzle 261 is equal to or lower than a predetermined threshold, it cannot be completely denied that the structure of the part supply area 2531 in the target feeder 25FB is not in a perfect match state. Therefore, if the normal suction rate FFR for the suction nozzle 261 is equal to or lower than a predetermined threshold (YES in step S54), the processing unit 71 outputs the mounting instruction data DA2 to which the match confirmation information DA23 has been added (step S55). The worker OP or the work robot can perform the task of confirming that the structure of the component supply area 2531 in the target feeder 25FB is actually in a fully compatible state according to the compatibility confirmation information DA23.

If the normal suction rate FFR for the suction nozzle 261 is not equal to or less than the predetermined threshold value (NO in step S54), the processing unit 71 outputs the mounting instruction data DA2 without adding the compatibility confirmation information DA23, and shifts processing from the mounting instruction process S5 to the update process S6.

(Update process)
When the operation of mounting the supply parts storage device 25AS on the target feeder 25FB in accordance with the mounting instruction data DA2 is completed, the worker OP or the work robot performs a reading operation to read the feeder recording unit 25R3 attached to the target feeder 25FB with a reading device 61 such as a barcode reader attached to the workbench 6, as shown in Fig. 16. This allows the feeder identification information FID recorded in the feeder recording unit 25R3 to be read as information relating to the target feeder 25FB on which the supply parts storage device 25AS is mounted.

After reading the feeder recording section 25R3 of the feeder 25FB to which the supply part storage device 25AS is attached, the worker OP or the work robot inserts the feeder 25FB to which the supply part storage device 25AS is attached into the storage unit 51 of the supply storage device 5B. As a result, the feeder 25FB to which the supply part storage device 25AS is attached is stored in the storage unit 51 of the supply storage device 5B as the feeder 25 to be replenished. The feeder 25 to be replenished stored in the storage unit 51 of the supply storage device 5B is replenished to the component supply unit 23 of the component mounter 2B by the exchange device 2C.

The feeder identification information FID of the target feeder 25FB on which the supply part storage device 25AS is attached, which is read by the reading device 61 on the workbench 6, is input to the parts supply management device 7. When the feeder identification information FID is input to the parts supply management device 7 after the mounting instruction process S5, the processing unit 71 performs an update process S6. In the update process S6, the processing unit 71 assumes that the structure of the parts supply area section 2531 in the target feeder 25FB has been changed in accordance with the structure change instruction information DA21 added to the mounting instruction data DA2, and updates the parts supply area information PSD associated with the feeder identification information FID of the target feeder 25FB for the feeder management data DZ3 stored in the memory unit 72. This allows the processing unit 71 to update the component supply area information PSD associated with the feeder identification information FID of the target feeder 25FB for the feeder management data DZ3 used when identifying the target feeder 25FB in the identification process S4 to information regarding the changed structure of the component supply area section 2531.

The component supply system 3 and component mounting system 1 according to an embodiment of the present invention have been described above, but the present invention is not limited to this, and for example, the following modified embodiments can be adopted.

In the above embodiment, the processing unit 71 of the parts supply management device 7 in the parts supply system 3 extracts, in the extraction process S3, from among the multiple feeders 25, multiple usable feeders 25FA that can be used for the supply parts storage device 25AS based on the parts-specific supply area data DZ1, the feeder location data DZ2, and the feeder management data DZ3 stored in the memory unit 72, but the present invention is not limited to this.

The extraction process S3 performed by the processing unit 71 of the parts supply management device 7 in the parts supply system 3 according to the modified embodiment will be described below with reference to FIG. 17.

In extraction process S3, the processing unit 71 acquires part-specific feeder data DZ4 and feeder location data DZ2 from the memory unit 72.

The component-specific feeder data DZ4 is data that associates component information PID for identifying the type of component with supplyable feeder information SFD for feeders 25 having a component supply area 2531 capable of supplying the component identified by the component information PID. The component information PID includes component name information PID1 indicating the name of the component, component size information PID2 indicating the size of the component, and component storage tape information PID3 regarding the component storage tape PT0 that stores the component. The supplyable feeder information SFD includes feeder identification information FID for feeders 25 having a component supply area 2531 capable of supplying the component identified by the component information PID.

The processing unit 71 extracts, based on the component-specific feeder data DZ4, the feeders 25 indicated by the feeder identification information FID included in the supplyable feeder information SFD associated with the component information PID related to the supply parts stored on the component storage tape PT0 of the supply part storage device 25AS, as multiple available feeders 25FA. In the component-specific feeder data DZ4, the feeder identification information FID included in the supplyable feeder information SFD associated with the component information PID related to the supply parts stored on the component storage tape PT0 of the supply part storage device 25AS is information for identifying the feeders 25 having the component supply area section 2531 capable of supplying supply parts. Therefore, the processing unit 71 can extract, as multiple available feeders 25FA, the feeders 25 indicated by the feeder identification information FID included in the supplyable feeder information SFD associated with the component information PID related to the supply parts in the component-specific feeder data DZ4.

Specifically, the processing unit 71 extracts, as the multiple available feeders 25FA, the feeder identification information FID included in the supplyable feeder information SFD associated with the part information PID related to the supply part in the part-specific feeder data DZ4, and the feeder 25 indicated by the feeder identification information FID in the location information WD of the feeder location data DZ2 indicating the storage unit 51 of the recovery storage device 5A.

In the part-specific feeder data DZ4, if the feeder identification information FID does not exist in the supplyable feeder information SFD associated with the part information PID related to the supply part stored in the part storage tape PT0 of the supply part storage device 25AS, the processing unit 71 extracts multiple usable feeders 25FA from the feeders 25 indicated by the feeder identification information FID that is not registered in the part-specific feeder data DZ4.

In addition, if the available feeder information SFD associated with one piece of part information PID in the part-specific feeder data DZ4 does not include multiple feeder identification information FID, the processing unit 71 cannot extract multiple available feeders 25FA. In this case, the processing unit 71 outputs error information ER.

The multiple available feeders 25FA extracted in the extraction process S3 of the processing unit 71 have a parts supply area 2531 that is structured to be able to supply replacement parts. Therefore, it is possible to select a feeder 25 that can accurately supply replacement parts from the multiple available feeders 25FA.

The specific embodiments described above mainly include inventions with the following configurations:

According to this component supply system, a plurality of feeders with different component supply area structures for each component storage member specification corresponding to the type of component are used as feeders for supplying components used in the production of component mounting boards in a component mounting machine. The plurality of feeders are managed by a management device. In a supply component recognition process, a processing unit of the management device recognizes a supply component storage device to which a component storage member that stores a supply component that is requested to be supplied to the component mounting machine is attached.

When mounting a supply part storage device in a feeder mounting section, it is necessary to select from among the multiple feeders a feeder having a parts supply area structured in accordance with the specifications of the parts storage member corresponding to the type of supply part. In the extraction process, the processing section of the management device extracts from among the multiple feeders multiple usable feeders that can be used for the supply part storage device, based on feeder identification information for identifying each of the multiple feeders. The feeder identification information is set in accordance with the structure of the parts supply area in the feeder. In other words, the feeder identification information is differentiated for each structure of the parts supply area. Therefore, the processing section can extract multiple usable feeders as feeders having a parts supply area structured to be able to supply the supply parts stored in the parts storage member of the supply part storage device, based on the feeder identification information differentiated for each structure of the parts supply area. The multiple usable feeders extracted in the extraction process of the processing section have parts supply area structures capable of supplying supply parts. Therefore, it is possible to select a feeder capable of accurately supplying supply parts from among the multiple usable feeders.

In the above-mentioned parts supply system, the parts supply area has a plurality of adjustment members capable of adjusting the supply of parts, and the structure can be changed according to the specifications of the parts storage member by the plurality of adjustment members. The management device has a storage unit that stores feeder management data in which parts supply area information relating to the structure of the parts supply area is associated with the feeder identification information. The processing unit recognizes the conformity status of the structure of the parts supply area in the plurality of available feeders with the specifications of the parts storage member in the supply parts storage device based on the parts supply area information associated with the feeder identification information of the plurality of available feeders, and performs identification processing to identify the target feeder to which the supply parts storage device is to be attached from among the plurality of available feeders according to the conformity status.

In this aspect, the processing unit can recognize the conformity of the structure of the parts supply area in the available feeder with the specifications of the parts storage member in the supply parts storage device, based on the parts supply area information associated with the feeder identification information of the multiple available feeders in the feeder management data. The processing unit then identifies a target feeder to which the supply parts storage device is to be attached from among the multiple available feeders, depending on the recognized conformity. The target feeder is a feeder identified depending on the conformity of the structure of the parts supply area with the specifications of the parts storage member that stores the supply parts, and therefore has a parts supply area that is structured to be able to supply the supply parts accurately.

The above-mentioned parts supply system may further include a storage device having a storage unit for storing the multiple available feeders and the target feeder. The processing unit performs mounting instruction processing for outputting mounting instruction data indicating an instruction to mount the supply part storage device to the mounting unit of the target feeder. The mounting instruction data includes storage unit information for identifying the storage unit that stores the target feeder.

In this embodiment, a worker or a work robot can perform the task of attaching the supply part storage device to the attachment portion of the target feeder according to the attachment instruction data output from the processing unit. When attaching the supply part storage device to the target feeder, the worker or the work robot can identify the storage unit that stores the target feeder according to the storage unit information included in the attachment instruction data.

In the above-mentioned parts supply system, the processing unit outputs notification instruction data to the storage device indicative of an instruction to notify the storage position of the feeder to be installed in the storage unit during the installation instruction process.

In this embodiment, the processing unit outputs notification instruction data to the storage device. The storage device can perform an operation to notify the storage position of the feeder to be attached in the storage unit in accordance with the notification instruction data. A worker or a work robot can ascertain the storage position of the feeder to be attached in the storage unit based on the notification operation by the storage device in accordance with the notification instruction data.

In the above-mentioned parts supply system, the processing unit performs an installation instruction process that outputs installation instruction data indicating an instruction to install the supply part storage device in the installation section of the target feeder. Then, when the processing unit recognizes in the identification process that the structure of the parts supply area section in the target feeder does not fully match the specifications of the parts storage member in the supply part storage device, the processing unit outputs the installation instruction data to which structure change instruction information indicating an instruction to change the structure of the parts supply area section by the multiple adjustment members is added in the installation instruction process.

In this aspect, when the structure of the part supply area in the feeder to be attached is not fully compatible with the specifications of the part storage material in the supply part storage device, the processing unit outputs attachment instruction data to which structure change instruction information has been added. The structure change instruction information is information that indicates an instruction to change the structure of the part supply area by a plurality of adjustment members. When the attachment instruction data to which structure change instruction information has been added is output from the processing unit, a worker or a work robot can perform work to change the structure of the part supply area in accordance with the structure change instruction information so that the structure of the part supply area fully complies with the specifications of the part storage material in the supply part storage device. The worker or the work robot can then perform work to attach the supply part storage device to the feeder to be attached in which the structure of the part supply area has been changed.

In the above-mentioned component supply system, the processing unit outputs the mounting instruction data to which change confirmation information indicating an instruction to confirm that the structure of the component supply area in the feeder to be mounted has been changed in accordance with the structure change instruction information is added during the mounting instruction process.

In this aspect, the processing unit outputs mounting instruction data to which structure change instruction information and change confirmation information have been added. The change confirmation information is information indicating an instruction to confirm that the structure of the component supply area in the feeder to be mounted has been changed in accordance with the structure change instruction information. When mounting instruction data to which structure change instruction information and change confirmation information have been added is output from the processing unit, a worker or a work robot can check, in accordance with the change confirmation information, whether or not work has been performed to change the structure of the component supply area in accordance with the structure change instruction information. This allows a worker or a work robot to more reliably perform work to change the structure of the component supply area.

In the above-mentioned component supply system, after the mounting instruction process, the processing unit performs an update process for updating the component supply area information associated with the feeder identification information of the feeder to be mounted for the feeder management data stored in the storage unit.

In this aspect, the processing unit assumes that the structure of the component supply area in the feeder to be attached has been changed in accordance with the structure change instruction information, and updates the feeder management data stored in the storage unit. This allows the processing unit to update the component supply area information associated with the feeder identification information of the feeder to be attached, for the feeder management data used when identifying the feeder to be attached in the identification process, to information regarding the structure of the component supply area after the change.

In the above-mentioned component supply system, if the processing unit recognizes in the identification process that the structure of the component supply area in the target feeder is in a perfect match state that is completely compatible with the specifications of the component storage member in the supply component storage device, then in the mounting instruction process, the processing unit outputs the mounting instruction data to which compatibility confirmation information has been added, which indicates an instruction to confirm that the perfect match state is achieved, in accordance with production performance data indicating the production performance of the component mounting board in the component mounter.

In this aspect, when the structure of the part supply area in the feeder to be attached is in perfect compatibility with the specifications of the part storage material in the supply part storage device, the processing unit outputs attachment instruction data to which compatibility confirmation information has been added according to the production performance data. The compatibility confirmation information is information indicating an instruction to confirm that the structure of the part supply area is in perfect compatibility with the specifications of the part storage material in the supply part storage device. When the attachment instruction data to which compatibility confirmation information has been added is output from the processing unit, a worker or a work robot can perform work to confirm that the structure of the part supply area is actually in perfect compatibility in accordance with the compatibility confirmation information. In this case, the worker or the work robot can perform work to attach the supply part storage device to the feeder to be attached, where the structure of the part supply area has been confirmed to be in perfect compatibility.

In this case, if there is no performance of the combination pattern of the supply component storage device and the feeder to be mounted in the production performance data, the processing unit outputs the mounting instruction data to which the compatibility confirmation information has been added.

If there is no record of a combination pattern of the supply part storage device and the feeder to be attached in the production performance data, the possibility that the structure of the parts supply area is not actually a perfect match cannot be completely denied. For this reason, if there is no record of a combination pattern of the supply part storage device and the feeder to be attached, the processing unit outputs attachment instruction data to which compatibility confirmation information has been added. A worker or a work robot can perform work to confirm that the structure of the parts supply area is actually a perfect match in accordance with the compatibility confirmation information.

In the above-mentioned component supply system, the production performance data includes information on the normal pickup rate, which indicates the percentage of components that are normally picked up by the suction nozzle. In this case, if the production performance data includes a pattern of combinations of the supply component storage device and the target feeder, and if the normal pickup rate is equal to or lower than a predetermined threshold, the processing unit outputs the mounting instruction data to which the compatibility confirmation information has been added.

Even if there is a record of a combination pattern of a supply part storage device and a feeder to be mounted in the production performance data, if the normal suction rate for the suction nozzle is below a predetermined threshold, the possibility that the structure of the part supply area is not actually a perfect match cannot be completely denied. For this reason, if the normal suction rate for the suction nozzle is below a predetermined threshold, the processing unit outputs mounting instruction data to which compatibility confirmation information has been added. A worker or a work robot can perform work to confirm that the structure of the part supply area is actually a perfect match in accordance with the compatibility confirmation information.

In the above-mentioned parts supply system, the processing unit, in the extraction process, acquires part-specific supply area data that associates part information for identifying the type of part with compatible area information regarding the structure of the part supply area that is compatible with the supply of the part indicated by the part information, and extracts the multiple usable feeders from among the multiple feeders based on the compatible area information associated with the part information regarding the parts stored in the part storage member of the spare part storage device and the feeder identification information of each of the multiple feeders.

Therefore, the processing unit can extract the feeders indicated by the feeder identification information associated in the part-specific feeder data with part information for the supply part as multiple available feeders.

In the above-mentioned parts supply system, if the feeder identification information associated with the part information related to the parts stored in the part storage member of the supply part storage device does not exist in the part-specific feeder data, the processing unit extracts the multiple usable feeders from among the feeders indicated by the feeder identification information not registered in the part-specific feeder data.

In this aspect, if there is no feeder identification information associated with part information related to a supply part in the part-specific feeder data, the processing unit can extract multiple usable feeders from among the feeders indicated by feeder identification information not registered in the part-specific feeder data.
