  Next, an embodiment of the present invention will be described with reference to the drawings. First, referring to FIG. 1 and FIG. 2, a component mounting device 2 in which a stick feeder 3 as a component supply device according to the present embodiment is arranged. The configuration will be described. The component mounting apparatus 2 and the stick feeder 3 constitute the component mounting system 1 shown in FIG. In FIG. 1, a substrate transport mechanism 5 is disposed in the center of a base 4 in the X direction (substrate transport direction). The substrate transport mechanism 5 transports the substrate 6 carried in from the upstream side, and positions and holds it on a mounting stage set for executing a component mounting operation.

  On both sides of the substrate transport mechanism 5, component supply units 7 are arranged. A plurality of tape feeders 8 are mounted in parallel on one component supply unit 7. The tape feeder 8 feeds components to a pickup position by the mounting head 12 of the component mounting mechanism 13 described below by pitch-feeding the carrier tape containing the components in the tape feeding direction.

  A stick feeder 3 is disposed along with a plurality of tape feeders 8 in the other component supply unit 7. Similarly, the stick feeder 3 has a function as a component supply device. As shown in FIG. 2, a stick case 23 having an opening in the length direction and containing a plurality of components therein is provided in the stacking unit 20. Store in a stacked state. The stick feeder 3 includes a stacking unit 20 and a component conveying unit 29. The component transport unit 29 is coupled to the mounting base unit 3b (see also FIG. 3) on the upper surface of the carriage 3a disposed in the component supply unit 7.

  The components ejected from the stick case 23 are conveyed by the component conveying section 29 to the pickup position 29a (FIG. 2) by the mounting head 12. Then, the conveyed component P is picked up by the mounting head 12 (arrow a), transferred to above the substrate 6, and mounted on the substrate 6 (arrow b). That is, the component mounting system 1 shown in the present embodiment is configured to include a stick feeder 3 and a component mounting device 2 as component supply devices.

  A Y-axis moving table 10 having a linear drive mechanism is disposed at one end in the X direction on the upper surface of the base 4. Similarly, two X-axis movement tables 11 each having a linear drive mechanism are coupled to the Y-axis movement table 10 so as to be movable in the Y direction. A mounting head 12 is mounted on each of the two X-axis moving tables 11 so as to be movable in the X direction.

  By driving the Y-axis movement table 10 and the X-axis movement table 11, the mounting head 12 moves in the X direction and the Y direction. As a result, the two mounting heads 12 take out components from the component supply positions by the tape feeder 8 and the stick feeder 3 arranged in the corresponding component supply units 7 and transfer them to the substrate 6 positioned by the substrate transport mechanism 5. Install. The Y-axis movement table 10, the X-axis movement table 11, and the mounting head 12 constitute a component mounting mechanism 13 that picks up and holds components from the component supply unit 7 and transfers them to the substrate 6 for mounting.

  A component recognition camera 14 is disposed between the component supply unit 7 and the substrate transport mechanism 5. When the mounting head 12 that has picked up the component P from the component supply unit 7 moves above the component recognition camera 14, the component recognition camera 14 captures and recognizes the component P held by the mounting head 12 (see FIG. 2). Mounted on the mounting head 12 are substrate recognition cameras 15 that are positioned on the lower surface side of the X-axis moving table 11 and move integrally with the mounting head 12.

  As the mounting head 12 moves, the substrate recognition camera 15 moves above the substrate 6 positioned by the substrate transport mechanism 5 and images and recognizes the substrate 6. In the component mounting operation on the board 6 by the mounting head 12, the mounting position correction is performed in consideration of the component recognition result by the component recognition camera 14 and the board recognition result by the board recognition camera 15. These recognition processing and position correction processing are executed by the component mounting apparatus control unit 16 arranged in the base 4.

  A signal device 17 that emits light in a predetermined light emission pattern instructed by the component mounting device control unit 16 is provided on the top of the component mounting device 2. The component mounting device control unit 16 operates the signal device 17 in accordance with a preset notification item such as an abnormal event, thereby notifying an operator of an abnormality occurring in the component mounting system 1.

  Next, the configuration and functions of the stick feeder 3 will be described with reference to FIG. The stick feeder 3 includes a stacking unit 20 that stores a plurality of stick cases 23 in a stacked state and a component conveying unit 29. The component transport unit 29 has a function of transporting a component discharged from the stored stick case 23 to a pickup position 29a by the mounting head 12 (FIG. 2) of the component mounting mechanism 13.

  The stacking unit 20 is disposed in a posture inclined in the component supply direction, and includes a first guide unit 21 and a second guide unit 22 disposed to face each other. The first guide part 21 and the second guide part 22 are configured to hold the stick case 23 between two plate-like members arranged in the paper surface direction. A stacking space for stacking a plurality of stick cases 23 is formed between the first guide portion 21 and the second guide portion 22.

  The stick case 23 is a hollow elongated container having both ends open, and a plurality of components are accommodated in series inside the stick case 23. That is, the stacking unit 20 has a function of stacking and holding a plurality of stick cases 23 storing a plurality of components in an inclined posture. A bar code label (not shown) indicating part information such as a part name and lot information of a part stored in the stick case 23 is attached to one side end surface of the stick case 23. Is set on the stacking unit 20, the operator reads the barcode label with the barcode reader, the component information is read, and the component verification process is performed.

  In the state where the stick case 23 is set in the stacking space between the first guide portion 21 and the second guide portion 22, both end portions in the longitudinal direction of the stick case 23 are the first guide portion 21 and the second guide portion 22. The position is maintained by being guided by. At this time, the stick case 23 is tilted in the component supply direction, and a component conveying force in the tilt direction due to gravity acts on the components stored in the stick case 23.

  Among the plurality of stick cases 23 stacked on the stacking portion 20, a sliding transport portion 27 is located at the opening of the stick case 23a located at the lowest level. The sliding conveyance unit 27 slides the components discharged and transferred from the opening of the stick case 23a by the above-described component conveyance force obliquely downward. An end portion of the sliding transport unit 27 is connected to a final transport unit 28 that is disposed horizontally. The final transport unit 28 includes a vibration unit 28a that moves the transferred parts by vibration.

  When a component that has slid through the sliding conveyance unit 27 is transferred to the final conveyance unit 28, the component moves on the final conveyance unit 28 toward the pickup position 29a. In other words, the final transport unit 28 transports the component that has slid through the sliding transport unit 27 to the pickup position 29a where the mounting head 12 of the component mounting apparatus 2 picks up the component.

  The sliding transport unit 27 and the final transport unit 28 are positioned at the opening of the stick case 23a positioned at the bottom of the plurality of stick cases 23 stacked on the stacking unit 20, and obliquely discharge the components discharged from the opening. A component transport unit 29 is configured to slide downward and transport the slid component to a pickup position 29a where the mounting head 12 of the component mounting apparatus 2 picks up the component. And in this Embodiment, the components conveyance part 29 is hold | maintained by the mounting base part 3b provided in the upper surface of the trolley | bogie 3a (refer FIG. 2). A control box 3c provided on the lower surface of the mounting base 3b incorporates a feeder controller 30 (see FIG. 4) for controlling each part of the stick feeder 3.

  The lowest position in the stacking unit 20 is a supply position where the stick case 23 to be supplied with the parts is positioned. The parts that have reached the pickup position 29a are sucked and held by the mounting head 12 and taken out. In the configuration described above, the stacking unit 20 is disposed so as to be inclined in the component supply direction, and the stick case 23 accommodated in the stacking unit 20 is transferred to the sliding transport unit 27 by gravity. You may arrange | position 20 horizontally, without making it incline. In this case, there is provided a component pushing mechanism that pushes out the components in the component mounting device control unit 16 by a rod-like pushing member and transfers them to the final transport unit 28.

  The second guide portion 22 opposite to the component supply direction is provided with a stick discharge mechanism 24 and a status display portion 25. The stick discharge mechanism 24 controls the advancing and retreating operations of the two locking members 24a and 24b into the stacking unit 20, thereby allowing the lowermost stick among the plurality of stick cases 23 housed in the stacking space. Only the case 23 a is dropped and discharged to the case collection unit 26. The state display unit 25 displays predetermined items such as the stacked state of the stick cases 23 in the stacking unit 20.

  The stick case 23 emptied by sending out all the parts P by the parts supply is discharged and dropped by the stick discharge mechanism 24 and is recovered by the case recovery unit 26. As a result, the next stick case 23b positioned immediately above the lowermost stick case 23a is positioned at the component supply position. In other words, the stick discharge mechanism 24 is a stick discard unit that discards the stick case 23a positioned at the lowest level from the stacking unit 20 and moves the stick case 23b that is one level higher to the lowest level. The drive timing of the stick discharge mechanism 24 as a stick discarding unit is controlled by a feeder control unit 30 (see FIG. 4) as a stick control unit.

  The stacking unit 20 is provided with a first component detection sensor SP1 including a pair of first component detection sensors SP1a (light emitting units) and a first component detection sensor SP1b (light receiving units) arranged to face each other. The first component detection sensor SP1 has a first component having an optical axis along a straight line connecting the pickup position 29a from the transfer position where the component P discharged from the stick case 23a is transferred from the sliding conveyance unit 27 to the final conveyance unit 28. It is a detection unit, and has a function of detecting the presence or absence of a component P on the component conveyance path from the transfer position to the pickup position 29a. When the first component detection unit detects that there is no component, component breakage is detected.

  In addition, a second component detection sensor SP2 composed of a pair of second component detection sensor SP2a (light emitting portion) and second component detection sensor SP2b (light receiving portion) is arranged on the upstream side of the transfer position in the sliding transport unit 27. Are arranged across the moving direction. The second component detection sensor SP2 is a second component detection unit having a function of detecting passage of a component that is ejected from the stick case 23 and moves to the pickup position 29a. Here, for convenience of illustration, the illustration of the second component detection sensor SP2b (light receiving unit) located on the back surface in the paper direction is omitted.

  Here, an example is shown in which the second component detection sensor SP2 is arranged in the sliding conveyance unit 27, but the second component detection sensor SP2 may be arranged in the final conveyance unit 28. That is, the second component detection unit in the present embodiment is arranged in the sliding conveyance unit 27 or the final conveyance unit 28. The first component detection unit and the second component detection unit described above constitute a component detection unit that detects components present in the component transport unit 29. As described above, in the present embodiment, the components present in the component transport unit 29 are detected by the two sensors, the first component detection unit and the second component detection unit. As a result, it is possible to detect component breakage or component clogging with a small number of sensors.

  The plate-shaped member constituting the first guide portion 21 of the stacking portion 20 includes a first sensor guide portion G1, a second sensor guide portion G2, and a third sensor guide portion G3 which are three elongated sensor mounting slits. The stick cases 23 in the stacking unit 20 are formed in parallel in the stacking direction. The first sensor guide part G1, the second sensor guide part G2, and the third sensor guide part G3 include a first stick detection sensor SS1a (light emitting part) and a second stick detection sensor SS2a (light emitting part) for detecting the stick case 23, respectively. ), The third stick detection sensor SS3a (light emitting unit) is slidably mounted in the stacking direction of the stick cases 23.

  Three sensor mounting slits similar to the first sensor guide part G1, the second sensor guide part G2, and the third sensor guide part G3 are also formed on the plate-like member on the back side of the paper surface constituting the first guide part 21. ing. In these sensor mounting slits, a light receiving section paired with the first stick detection sensor SS1a (light emitting section), the second stick detection sensor SS2a (light emitting section), and the third stick detection sensor SS3a (light emitting section) is mounted. Has been. In addition, illustration of these light-receiving parts located in the back surface in the paper direction is omitted here.

  The first stick detection sensor SS1a (light emitting unit), the second stick detection sensor SS2a (light emitting unit), the third stick detection sensor SS3a (light emitting unit) and the light receiving unit paired therewith are the first stick detection sensor SS1, A two-stick detection sensor SS2 and a third stick detection sensor SS3 are configured. The first stick detection sensor SS1 detects the stick case 23b that is one step above the stick case 23a that is positioned at the bottom of the stacking unit 20. The second stick detection sensor SS2 and the third stick detection sensor SS3 respectively detect the two upper stick cases 23c and the three upper stick cases 23d of the stick case 23a located at the lowermost stage.

  The first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3 are respectively a first sensor guide part G1, a second sensor guide part G2, and a fastener that can be fastened and unfastened, such as a bolt. The third sensor guide part G3 is mounted in a variable position. That is, the stacking unit 20 includes a sensor guide unit that guides the movement of the first stick detection sensor SS1 and the second stick detection sensor SS2 in the stacking direction, and more specifically guides the first stick detection sensor SS1. The first sensor guide part G1 and the second sensor guide part G2 for guiding the second stick detection sensor SS2 are provided.

  In other words, the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3 are attached to the first guide portion 21 in a state where the attachment positions in the stacking direction of the stick cases can be adjusted. . As a result, even when stick cases 23 having different thickness dimensions are stacked on the stacking unit 20, it is possible to accurately detect the presence or absence of the stick case 23 existing at each stacking position, and the versatility is excellent. A stick feeder 3 is realized.

  Next, the configuration of the control system will be described with reference to FIG. 4, the feeder control unit 30 includes a stick discharge mechanism 24, a first part detection sensor SP1, a second part detection sensor SP2, a first stick detection sensor SS1, a second stick detection sensor SS2, and a third part shown in FIG. The stick detection sensor SS3, the vibration unit 28a, and the state display unit 25 are connected. The feeder control unit 30 includes, as internal processing functions, a stick empty determination unit 31, a component outage determination unit 32, a component clogging determination unit 33, and a stacking unit state determination unit 34, and further includes a storage unit 35. .

  The feeder control unit 30 is connected to the component mounting device control unit 16 of the component mounting device 2 via the communication unit 36, and can exchange information with the component mounting device 2. The component mounting apparatus 2 includes a signal device 17 (see FIG. 2) that emits light in a predetermined light emission pattern instructed by the component mounting apparatus control unit 16. The signal device 17 is turned on by a command from the component mounting device control unit 16 for a predetermined item set in advance, and notifies the operator of that fact.

  Further, the component mounting device control unit 16 is connected to a monitoring system 37 and a production information collecting system 38. The monitoring system 37 has a function of monitoring the operating status of each device in the component mounting system 1, and can notify a worker of predetermined items via a portable terminal or the like as a monitoring device carried by the worker. It can be done. The production information collection system 38 creates production history information indicating the execution history of the component mounting work executed in the component mounting system 1. That is, the component name and lot information of the mounted component are collected for each board that is a work target.

  The storage unit 35 stores component information that is information about components stored in the plurality of stick cases 23 stacked on the stacking unit 20. That is, in the storage unit 35, a storage area MR1, a storage area MR2, a storage area MR3, a storage area MR4,... In the storage area MR1, storage area MR2, storage area MR3,..., Parts information including at least the part name and lot information of the parts stored in the stick case 23a, stick case 23b, stick case 23c,. Is memorized. Therefore, the storage unit 35 is a component information storage unit that stores component information.

  If the second component detection sensor SP2 which is the second component detector does not detect any component, the stick empty determination unit 31 determines that all components have been discharged from the stick case 23a located at the lowest level. The second part detection sensor SP2 having an optical axis that traverses the stick empty determination part 31 and the sliding transport part 27 includes a stick empty detection part that detects that all parts have been discharged from the stick case 23a located at the lowest level. It is composed.

  When the first component detection sensor SP1, which is the first component detection unit, no longer detects a component, the component run-out determination unit 32 determines that the component on the component transport unit 29 has been exhausted. The first component detection unit and the component outage determination unit 32 constitute a component outage detection unit that detects that there is no component on the component transport unit 29.

  When the first component detection unit or the second component detection unit described above no longer detects a component, the feeder control unit 30 drives the stick discharge mechanism 24 to discharge the stick case 23a located at the lowest level. At this time, the feeder control unit 30 refers to the component information stored in the storage unit 35. In other words, the feeder control unit 30 drives the stick discharge mechanism 24, which is a stick discard unit, based on the detection result of the stick empty detection unit or the component cut detection unit and the component information.

  Then, the feeder control unit 30 drives the stick discharge mechanism 24 to discharge the stick case 23, and if the first component detection unit or the second component detection unit detects no component within a predetermined time, the component is It is determined that an abnormality such as “part clogging” that is not normally conveyed or “stick clogging” in which the stick case 23 does not move normally has occurred, and the fact is notified to the part mounting device 2 via the communication unit 36.

  When the component mounting apparatus 2 receives the notification of the abnormality, the component mounting apparatus 2 notifies the operator that the abnormality has occurred by the notification unit. Here, the component mounting device control unit 16 that controls the component mounting device 2 and the signal device 17 that emits light in a predetermined light emission pattern instructed by the component mounting device control unit 16 function as a notification unit. In addition, you may use the portable terminal connected to the monitoring system 37 which monitors the state of the components mounting apparatus 2 as an alerting | reporting part.

  If the first part detection sensor SP1 or the second part detection sensor SP2 does not detect the part even after a predetermined time has elapsed after discarding the stick case 23, the part clogging determination unit 33 determines whether the part is in any part. Judgment is made that there is an abnormality in the remaining part clogging and the part clogging is determined. The stacking unit state determination unit 34 performs a process for determining the stacking state of the stick case 23 in the stacking unit 20. The determination result by the loading unit state determination unit 34 is displayed on the state display unit 25.

  The feeder control unit 30 drives the stick discharge mechanism 24 as a stick discard unit based on the detection results of the stick empty determination unit 31 and the component outage determination unit 32 and the component information stored in the storage unit 35. That is, the feeder control unit 30 has a function as a stick control unit that controls the drive timing of the stick discharge mechanism 24. The stick control unit determines the stacking state of the stick case 23 using the processing function of the stacking unit state determination unit 34. That is, the stacking state of the stick case 23 in the stacking unit 20 is determined from the detection results of the component detection unit and the first stick detection sensor SS1 and the second stick detection sensor SS2.

  Here, with reference to FIG. 5, the determination of the stacking state by the stacking unit state determination unit 34 will be described. In FIG. 5, “stick detection sensor” 40, “component detection sensor” 41, and “part name collation result immediately before stick ejection” 42 described in the column direction are used to determine the stacking state of the stick case 23 in the stacking unit 20. This is a determination condition item that is a condition for performing.

  “Stick detection sensor” 40 indicates a stick detection result by the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3. “Part detection sensor” 41 indicates the first part detection sensor. The component detection result by SP1 and 2nd component detection sensor SP2 is shown. In the “stick detection sensor” 40 and the “component detection sensor” 41, a circle indicates that a stick or a component has been detected, and a cross indicates that a stick or component has not been detected.

  The “part name collation result immediately before stick ejection” 42 is a part name collation result just before stick ejection, that is, a part stored in the lowermost stick case 23a and a part stored in the upper stick case 23b. The result of collating names is shown. This part name collation is performed based on the part information stored in the storage unit 35. The “loading state” 43 indicates the determination result of the loading state corresponding to these determination condition items.

  The determination patterns 44 a to 44 j described in the row direction in FIG. 5 are determination patterns indicating the correspondence between the determination condition item and the “loading state” 43. In the determination patterns 44a to 44c, the stick case 23 is detected in order from the lower stage in the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3. As a result, in the “stacked state” 43, a determination of “stacked” indicating that the stick case 23 is normally stacked on the stacking unit 20 is made.

  In the determination pattern 44d, the stick case 23 is not detected in any of the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3, and the component is detected in the second component detection sensor SP2. . In the “part name collation result immediately before stick ejection” 42, the part name collation result is “same”. In this case, in the “loading state” 43, it is determined that “there is only the lowermost stage” indicating that the stick case 23 a exists only in the lowermost stage of the stacking unit 20.

  In the determination pattern 44e, the stick case 23 is not detected in any of the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3, and no component is detected in the second component detection sensor SP2. . In the “part name collation result immediately before stick ejection” 42, the part name collation result is “same”. In this case, in the “loading state” 43, “empty” is determined to indicate that the stick case 23 does not exist in the stacking unit 20 including the lowermost stage of the stacking unit 20.

  In the determination pattern 44f, the stick case 23 is not detected in any of the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3, and the component is detected in the first component detection sensor SP1. . In the “part name collation result immediately before stick ejection” 42, the part name collation result is “not identical”. In this case, in the “loading state” 43, a determination is made that “there is only the lowermost stage” indicating that the stick case 23 exists only in the lowermost stage of the stacking unit 20.

  In the determination pattern 44g, the stick case 23 is not detected in any of the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3, and no component is detected in the first component detection sensor SP1. . In the “part name collation result immediately before stick ejection” 42, the part name collation result is “not identical”. In this case, in the “loading state” 43, “empty” is determined to indicate that the stick case 23 does not exist including the lowermost stage of the stacking unit 20.

  In the determination patterns 44h to 44j, the stick case 23 is detected although the stick case 23 is detected in at least one of the first stick detection sensor SS1, the second stick detection sensor SS2, and the third stick detection sensor SS3. There is a gap where the stick case 23 does not exist at the lower stage. In such a case, a determination is made of “stick clogging” in which the stick case 23 does not move downward normally.

  The relationship between the determination condition item and the determination pattern is stored as determination pattern data in the storage unit 35 of the feeder control unit 30. In the switching process of the stick case 23 described below, the feeder control unit 30 as a stick control unit controls the stick feeder 3 with reference to the determination pattern data, and discards the stick case 23, “parts clogged”, and the like. Notification of “stick clogging”.

  Next, the switching process of the stick case 23 in the stick feeder 3 arranged in the component mounting apparatus 2 constituting the component mounting system 1 will be described with reference to FIG. In FIG. 6, it is first determined whether or not the stacking unit 20 is empty (ST1). If it is determined that the parts are not empty, it is next determined whether or not the parts are the same (ST2). That is, the feeder control unit 30 compares the component information of the stick case 23a located at the lowest level of the stacking unit 20 with the component information of the upper stick case 23b. In the comparison of the component information, the feeder control unit 30 determines whether the components are the same by the component name, the lot information, or both the component name and the lot information.

  If it is determined that they are the same, it is determined whether or not the current stick is empty (ST3). That is, it is determined by the function of the stick empty detection unit whether or not all parts have been discharged from the stick case 23a located at the lowermost stage. If it is determined in (ST1) that the stacking unit 20 is empty, or if it is determined in (ST2) that the parts are not the same, it is determined whether or not a part has run out (ST4). That is, it is determined whether or not there is no component on the component transport unit 29 by the function of the component cut detection unit. If it is determined that there is a part in (ST3) and (ST4), the process returns to (ST1) and repeats the same processing.

  If it is determined in (ST3) that the current stick is empty, or if it is determined in (ST4) that a component has run out, the stick discharge mechanism 24 is driven to execute a stick discarding operation (ST5). . That is, the stick case 23a located at the lowest level is discarded from the stacking unit 20, and the stick case 23b one level above is moved to the lowest level.

  In executing the stick discarding operation, if the feeder control unit 30 determines that the components are the same as a result of the comparison of the component information, the stick case positioned at the bottom of the stacking unit 20 by the stick empty detection unit. When it is detected that 23a is empty, the stick discard unit is driven. If it is determined that the parts are not the same, the stick discarding unit is driven when it is detected by the component cut detection unit that there are no components on the component transport unit 29.

  Then, the stick case 23 is switched by this stick discarding operation, and the discharge of the parts is started from the new stick case 23a in which the upper stick case 23b has moved to the lowermost stage. Here, the part clogging determination unit 33 determines whether there is a part clogging (ST6). That is, after the stick case 23 is discarded, if the first component detection sensor SP1 or the second component detection sensor SP2 does not detect a component even after a predetermined time has elapsed, it is determined that a component clogging abnormality has occurred, The component mounting device 2 is notified of “component clogging” (ST7).

  If there is no part clogging in (ST6), the presence / absence of stick clogging is determined (ST8). That is, the feeder control unit 30 refers to the determination pattern data shown in FIG. 5 to determine whether stick clogging has occurred (ST8). If stick clogging has occurred, “stick clogging” is notified to the component mounting apparatus 2 (ST9). If there is no stick clogging in (ST9), the part name and lot information are transmitted together with the update of the part information written in the storage unit 35 (ST10).

  That is, the component information written in the storage area MR1 corresponding to the lowermost stick case 23a is updated with the component information written in the storage area MR2 corresponding to the upper stick case 23b. The component name and lot information of the rewritten component information are transmitted to the component mounting apparatus 2.

  As described above, when the feeder control unit 30 determines that the parts are not the same as a result of the comparison of the part information, the feeder control unit 30 is included in the part information of the stick case 23b immediately above the discarded stick case 23a. Either or both of the part name and the lot information are transmitted to the part mounting apparatus 2. The component mounting apparatus control unit 16 that has received the component information transmits the component information to the production information collection system 38. Then, the production information collection system 38 creates and stores production history information that associates the board information to be produced with these parts information.

  In this component mounting operation, the following operations and processes are executed. That is, the component is detected by the first component detection sensor SP1 (first component detection unit) having an optical axis along a straight line extending from the position where the component moves from the sliding conveyance unit 27 to the final conveyance unit 28 to the pickup position 29a. . At the same time, the component is detected by the second component detection sensor SP2 (second component detection unit) that is disposed in the sliding conveyance unit 27 or the final conveyance unit 28 and has an optical axis that crosses the moving direction of the component.

  At this time, if the first component detection unit or the second component detection unit no longer detects a component, the stick case 23a positioned at the lowest stage of the stacking unit 20 is discarded from the stacking unit 20 by the stick discharge mechanism 24, and one of the cases. The upper stick case 23b is moved to the lowest level. Next, the parts discharged from the stick case 23a newly moved to the lowest stage are transported from the sliding transport section 27 to the pickup position 29a via the final transport section 28. Then, after the new stick case 23a is moved to the lowest stage, if the first component detection unit or the second component detection unit does not detect the component within a predetermined time, the component mounting apparatus 2 is notified of the abnormality.

  Next, a second method included in the component mounting method described above will be described. In the second method, first, a part discharged from the opening of the stick case 23a positioned at the lowest stage among the plurality of stick cases 23 stacked and held on the stacking unit 20 is slid, and the slid part is used as a part. The mounting head 12 of the mounting apparatus 2 conveys the component to a pickup position 29a where the component is picked up. Next, the component conveyed to the pickup position 29 a is picked up by the mounting head 12 of the component mounting apparatus 2 and mounted on the substrate 6.

  Then, the component information of the stick case 23a located at the lowest level is compared with the component information of the upper stick case 23b. If it is determined in the component information comparison that the components are the same, if it is detected that the lowermost stick case 23a is empty, the lowermost stick case 23a is loaded into the stacking unit 20. The stick case 23b is moved to the lowermost stage.

  If it is determined that the parts are not the same, when it is detected that all parts are removed from the parts transport unit 29, the stick case 23 a located at the lowest level is discarded from the stacking unit 20. The stick case 23b is moved to the lowermost stage. Next, the parts ejected from the stick case 23 newly moved to the lowermost stage are transported to the pickup position 29 a, picked up by the mounting head 12, and mounted on the substrate 6.

  Note that, in the comparison of the component information described above, the feeder control unit 30 determines whether the components are the same by the component name, the lot information, or both the component name and the lot information. If it is determined that the parts are not the same, either or both of the part name and the lot information included in the part information of the stick case 23b immediately above the discarded stick case 23a are transmitted to the part mounting apparatus 2.
