Description

Component replenishment management device, component mounting system, and method of managing usage history of component storage member

This invention relates to a technique for setting a component storage member on a feeder that supplies components mounted on a substrate from the component storage member.

Conventionally, in order to produce a component mounting substrate by mounting components on a substrate, a feeder that supplies components stored in a component storage member such as a supply reel has been used. In the configuration in which components are supplied from the component storage member by the feeder in this way, as shown in Patent Document 1, for example, the component supply member is appropriately mounted on the feeder according to the timing when the component storage member is used up. There is a need to.

JP 2011-204824 A

By the way, the parts of the parts storage member are not always used up at one time, and may remain. In such a case, it is preferable from the viewpoint of suppressing the waste of components that a used component storage member in which some components are used can be reused for component mounting. However, in the situation where there is a new component storage member, a plurality of different used component storage members, etc., since the use history of each component storage member is different, the component storage member suitable for reuse in component mounting, Other component storage members may be mixed. Therefore, in order to select a component storage member having an appropriate usage history for component mounting, a technique for confirming the usage history of the component storage member has been demanded.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique that makes it possible to check the usage history of a component storage member that stores components mounted on a substrate.

The component replenishment management device according to the present invention includes a storage unit that stores usage history information in which a usage history of a component storage member that stores a component mounted on a board is associated with an identifier that identifies the component storage member, and a usage history A control unit that confirms the usage history of the component storage member indicated by the identifier by referring to the information.

The method for managing the usage history of the component storage member according to the present invention refers to the usage history information in which the usage history of the component storage member storing the component mounted on the board is associated with the identifier for identifying the component storage member. And a step of confirming the usage history of the component storage member indicated by the identifier.

According to the present invention configured as described above (component supply management device, component storage member usage history management method), the component storage member usage history for storing components mounted on the board is identified by the component storage member. Usage history information associated with the identifier to be used is used. That is, by referring to this usage history information, it is possible to confirm the usage history of the component storage member from the identifier of the component storage member.

Incidentally, the present invention can be suitably applied to the execution of a production plan for producing a component mounting board by mounting the component on the board by using a feeder that performs a component supply operation for supplying the component from the mounted component storage member. . That is, at the production site of the component mounting board, all the components of the component storage member are not always used up every time the board is produced, and a used component storage member using some components may be generated. For this reason, there are cases where a plurality of target storage members including new and used ones can be used for the mounting work on the feeder, and there is a need to replenish parts with an appropriate target storage member while checking the usage history of the component storage members. .

Therefore, the control unit uses a feeder that performs a component supply operation to supply a component from the mounted component storage member, and mounts the component on the substrate to produce a component mounting board. After the part is cut, a determination process is performed to determine another component storage member to be used for the mounting operation of mounting another component storage member for storing the component on the feeder. The determination process can be used for the mounting operation. When there are a plurality of target storage members having different component storage numbers as different component storage members, it is determined that one target storage member selected based on the usage history of each of the plurality of target storage members is used for the mounting operation. In this way, a parts supply management device may be configured. In such a configuration, it is possible to select an appropriate target storage member based on the usage history and use it in the production plan, and while using the used component storage member efficiently, an appropriate number of parts for the production plan Can be replenished.

In addition, the usage history includes the number of parts stored in the part storage member identified by the corresponding identifier as the remaining number of parts. In the determination process, the number of parts to be supplied by the feeder according to the production plan and a plurality of targets are determined. The parts supply management device may be configured to select one target storage member based on the remaining number of parts of each storage member. In such a configuration, it is possible to select an appropriate target storage member based on the number of remaining parts and use it in a production plan. Parts can be replenished.

In addition, the control unit sets a first reference time indicating the execution timing of the mounting operation, and selects one target storage member to be used in the mounting operation executed corresponding to the first reference time in the determination process. In addition, a component supply management device may be configured. Thereby, in the mounting work according to the first reference time, it is possible to use one appropriate target storage member selected based on the remaining number of parts.

In addition, in the determination process, one target storage member is selected based on the number of parts that the feeder plans to supply from the first reference time to the end of the production plan according to the production plan and the remaining number of parts of each of the plurality of target storage members. The parts supply management device may be configured to select. In such a configuration, it is possible to select one target storage member that has an appropriate number of remaining parts for component mounting from the first reference time to the end of the production plan and use it for the mounting operation.

In addition, the control unit sets a second reference time indicating the timing of the mounting work after the first reference time, and in the determination process, the feeder is scheduled to supply from the first reference time to the second reference time according to the production plan. The parts supply management device may be configured to select one target storage member based on the number of parts and the remaining number of parts of each of the plurality of target storage members. In such a configuration, it is possible to select one target storage member that has an appropriate number of remaining parts for component mounting from the first reference time to the second reference time and use it for the mounting operation.

In addition, the feeder executes the component supply operation using the plurality of mounted component storage members in order, and in the determination process, the feeder is more than the remaining number of components in use in the component supply operation at the first reference time. If it is determined that the number of remaining parts of another component storage member is small, the component replenishment management device is configured to determine that the mounting operation is performed while switching the component storage member used for the component supply operation to another component storage member. May be. With such a configuration, it is possible to secure a long wearable period that occurs next to the mounting work according to the first reference time, and it is possible to create a time margin that can be used for the mounting work to be executed according to the wearable period. Here, the mountable period is a predetermined number of remaining parts, which is the total number of parts remaining in the plurality of component storage members after the first one of the plurality of component storage members is cut. It is a period to decrease to.

In addition, the component supply member is a component supply reel in which a component supply tape in which a carrier tape that stores a plurality of components is covered with a cover tape is wound around a shaft, and the cover tape is removed from the carrier tape and collected by a recovery mechanism. The component supply reel can be used with two types of feeders, the first type feeder that exposes the parts in the above and the second type feeder that exposes the parts by opening the cover tape. In the determination process, including the type of feeder used, the component replenishment management device is forbidden to mount the component supply member used for the component supply operation by the second type feeder on the first type feeder in the mounting operation. May be configured.

That is, when the component supply tape is attached to the first type feeder, in order to attach the front end of the cover tape to the recovery mechanism, the front end portion of the cover tape needs to be peeled off from the carrier tape. Therefore, a new part supply tape is usually provided with a leader part in which no part is accommodated, and the cover tape of the reater part is attached to the recovery mechanism. On the other hand, a used parts supply tape having a history of use in the type 2 feeder does not have such a leader. Therefore, in order to attach this used parts supply tape to the first type feeder, it is necessary to peel the cover tape from the carrier tape for attachment to the recovery mechanism, and the parts stored in the peeled part are useless. Become. On the other hand, by prohibiting the mounting of the component supply member used for the component supply operation by the second type feeder to the first type feeder in the mounting operation, waste of components can be suppressed.

In addition, when the control unit selects a component storage member in which some of the components are used as one component storage member, the control unit stores one component in a feeder other than the feeder that is the target of the mounting work among a plurality of feeders. The parts replenishment management device may be configured to prohibit the mounting of members. In such a configuration, it is possible to prevent the used component storage member from being erroneously mounted on a feeder different from the mounting work target.

In addition, an identifier acquisition unit that acquires the identifier of the component supply member and a notification unit that notifies the operator are further provided. When the identifier acquisition unit acquires the identifier of one component storage member, the control unit performs one operation in the mounting operation. The component replenishment management device may be configured so that a feeder that is a mounting target of the component storage member is notified by the notification unit. With such a configuration, it is possible to reliably mount one component storage member to be mounted on an appropriate feeder.

The component mounting system according to the present invention is a component that executes a production plan for producing a component mounting board by mounting the component on the board using a feeder that performs a component supply operation for supplying the component from the mounted component storage member. A mounting machine and the above-described component supply management device are provided. Therefore, it is possible to check the usage history of the component storage member that stores components mounted on the board.

According to the present invention, it is possible to check the usage history of a component storage member that stores components mounted on a board.

FIG. 1 is a plan view schematically showing a component mounter which is an example of a management target by a component supply management device according to the present invention. In the figure, XYZ orthogonal coordinates composed of a Z direction parallel to the vertical direction and an X direction and a Y direction parallel to the horizontal direction are shown. The component mounting machine 1 includes a pair of

conveyors

12 and 12 provided on a base 11. Then, the component mounting machine 1 mounts the components on the board B carried into the work position (position of the board B in FIG. 1) from the upstream side in the X direction (board transport direction) by the conveyor 12, and completes the component mounting. The substrate B is carried out from the work position to the downstream side in the X direction by the conveyor 12.

The component mounter 1 is provided with a pair of Y-

axis rails

21, 21 extending in the Y direction, a Y-axis ball screw 22 extending in the Y direction, and a Y-axis motor My that rotationally drives the Y-axis ball screw 22, and a head support member 23 is fixed to the nut of the Y-axis ball screw 22 while being supported by the pair of Y-

axis rails

21 and 21 so as to be movable in the Y direction. An X-axis ball screw 24 extending in the X direction and an X-axis motor Mx that rotationally drives the X-axis ball screw 24 are attached to the head support member 23, and the head unit 3 can move to the head support member 23 in the X direction. The nut is fixed to the nut of the X-axis ball screw 24 while being supported by the nut. Therefore, the Y-axis ball screw 22 is rotated by the Y-axis motor My to move the head unit 3 in the Y direction, or the X-axis ball screw 24 is rotated by the X-axis motor Mx to move the head unit 3 in the X direction. it can.

The two component supply units 25 are arranged in the X direction on each side of the pair of

conveyors

12 and 12 in the Y direction, and the feeder mounting cart 4 is detachably attached to each component supply unit 25. A plurality of tape feeders 5 arranged in the X direction and a plurality of reel holders 6 arranged in the X direction are detachably mounted on the feeder mounting carriage 4, and one tape feeder 5 and one reel holder are mounted. 6 are associated with each other and arranged in the Y direction.

The component supply reel 7 held by each reel holder 6 has a component supply tape TP in which small pieces (chip electronic components) such as an integrated circuit, a transistor, and a capacitor are stored at predetermined intervals. The component supply tape TP includes a carrier tape that stores components in each of a plurality of pockets arranged in a line at an equal pitch, and a cover tape that is attached to the carrier tape and covers the components in the pockets. On one side of the carrier tape TP, a plurality of engagement holes arranged at regular intervals pass through the edge. As will be described later, two carrier tapes TP can be attached to each tape feeder 5, and correspondingly, each reel holder 6 holds two component supply reels 7 arranged in the Y direction. . Then, each tape feeder 5 intermittently feeds the carrier tape TP pulled out from the component supply reel 7 in the reel holder 6 adjacent in the Y direction to the head unit 3 side, so that the components in the carrier tape TP are predetermined. Supply to the component supply position 50 (component supply operation).

The head unit 3 has a plurality (four) of mounting heads 31 arranged in the X direction. Each mounting head 31 has a long shape extending in the Z direction (vertical direction), and can suck and hold components by a nozzle that is detachably attached to the lower end thereof. That is, the mounting head 31 moves above the tape feeder 5 and sucks the components supplied by the tape feeder 5. Subsequently, the mounting head 31 mounts the component on the board B by moving above the board B at the work position and releasing the suction of the component. In this way, the mounting head 31 executes component mounting in which the component supplied to the component supply position 50 by the tape feeder 5 is taken out from the carrier tape TP and mounted on the substrate B.

FIG. 2 is a side view schematically showing an example of the configuration and operation of the tape feeder. In this figure and the following drawings, the feed direction Df (parallel to the Y direction) in which the tape feeder 5 feeds out the carrier tape TP is appropriately shown, and the arrow side of the feed direction Df is set to “front” of the feed direction Df and the feed direction Df. The other side of the arrow is treated as “rear” in the feed direction Df. Further, in order to distinguish between the two carrier tapes TP that can be attached to the tape feeder 5, in the figure and the following figures, different symbols TP1 and TP2 are appropriately used for the carrier tape.

The tape feeder 5 includes a feeder main body 51 that is a mechanical configuration, and motors Mf and Mb that drive the feeder main body 51. The feeder body 51 has a flat case 52 that is thin in the X direction and long in the feed direction Df. At the rear end of the feed direction Df of the case 52, a tape insertion opening 53a (shown by a broken line) extending in the Z direction opens, and the above-described component supply position 50 is provided on the upper surface of the case 52 in the feed direction Df. It has been. In the feeder main body 51, a tape transport path 53b extending from the tape insertion port 53a to the component supply position 50 is provided. The feeder main body 51 supplies the component to the component supply position 50 by sending the carrier tape TP inserted into the tape transport path 53b from the tape insertion port 53a in the feed direction Df under the driving force of the motors Mf and Mb. To do.

Specifically, the feeder main body 51 includes a sprocket 54 disposed adjacent to the tape insertion port 53a above the tape conveyance path 53b and a gear 55 that transmits the driving force of the motor Mb to the sprocket 54. The sprocket 54 rotates upon receiving a driving force generated by the motor Mb. Furthermore, the feeder main body 51 has a tape support member 56 that is detachably attached to the case 52. The tape support member 56 faces the sprocket 54 from below, and the carrier tape TP is engaged with the sprocket 54 by sandwiching the carrier tape TP between the tape support member 56 and the sprocket 54. Thus, the sprocket 54 rotates while engaging with the carrier tape TP, so that the carrier tape TP can be sent out in the feed direction Df. The feeder main body 51 has a sprocket 57 disposed at the front end portion thereof and adjacent to the tape transport path 53b from below and a gear 58 for transmitting the driving force of the motor Mf to the sprocket 57 in the case 52. 57 rotates by receiving the driving force generated by the motor Mf. Therefore, the sprocket 57 can intermittently convey the carrier tape TP in the feed direction Df by rotating intermittently while engaging the carrier tape TP.

Further, the feeder main body 51 has a cutter that contacts the component supply tape TP on the upstream side of the feed direction Df of the component supply position 50. This cutter exposes the component supplied to the component supply position 50 by tearing the cover tape of the component supply tape TP, which is intermittently conveyed in the feed direction Df, at the center and scooping it to both sides. The configuration for exposing the components in this way is the same as that described in, for example, Japanese Patent Application Laid-Open No. 2015-053320.

Step S11 corresponds to a state in which the tape feeder 5 is used for component mounting by the mounting head 31. That is, the carrier tape TP1 is inserted into the feeder main body 51 along the tape transport path 53b, and the sprocket 57 intermittently transports the carrier tape TP1 in the feed direction Df, so that the component mounted on the board B is a component. Supply to supply position 50. In step S 11, the tip of the carrier tape TP 2 used for component mounting next to the carrier tape TP 1 is attached between the sprocket 54 and the tape support member 56. Thus, the carrier tape TP2 to be used next stands by at the rear end portion of the feeder main body 51.

As shown in step S12, when the parts in the carrier tape TP1 are used up and the tape feeder 5 ejects the carrier tape TP1, loading shown in step S13 is executed. Specifically, the sprocket 54 starts rotating and feeds the carrier tape TP2 toward the component supply position 50 in the feed direction Df, and the tip of the carrier tape TP2 is engaged with the sprocket 57. Subsequently, when the operator performs an operation of removing the tape support member 56 from the case 52 in step S14, the carrier tape TP2 is detached from the sprocket 54 and falls to the tape transport path 53b. Thus, the sprocket 57 can intermittently convey the carrier tape TP2 in the feed direction Df and supply the components in the carrier tape TP2 to the component supply position 50. Incidentally, after step S14, the operator attaches the tape support member 56 to the case 52 again, thereby attaching the carrier tape TP used for component mounting next to the carrier tape TP2 between the sprocket 54 and the tape support member 56. Can wait.

In the component mounting machine 1 using such a tape feeder 5, the carrier tape TP being used is inserted into the feeder main body 51 along the tape conveyance path 53b, while the carrier tape TP to be used next is the tape conveyance. Waits above the path 53b. By performing steps S12 to S14 each time the carrier tape TP is used up, the waiting carrier tape TP can be inserted into the feeder main body 51 along the tape transport path 53b and used next.

FIG. 3 is a diagram schematically showing an example of a component supply reel and a reel holder that holds the component supply reel. In FIG. 3, the component supply reel 7 is shown through the reel holder 6. The component supply reel 7 has an axis 71 and two side plates 72 sandwiching the axis 71 from both sides, and supports the component supply tape TP wound around the axis 71 from both sides by the side plate 72. The reel 7 has a reel ID 73 and a component ID 74 each formed of a barcode on the side plate 72. The reel ID 73 is unique and can be used to individually identify the component supply reel 7 to which the reel ID 73 is attached. The component ID 74 indicates information (component type, number, expiration date, etc.) regarding components stored in the component supply tape TP of the component supply reel 7 to which the component ID 74 is attached. Note that the reel ID 73 and the component ID 74 are not necessarily configured by separate barcodes, and may be configured by one barcode.

The reel holder 6 can hold the component supply reel 7 at each of the use position Lu and the standby position Lw behind the use direction Lu in the feed direction Df. The component supply tape TP of the component supply reel 7 held at the use position Lu is loaded on the tape feeder 5 and used for component supply in component mounting, while the component supply reel 7 held at the standby position Lw is used. The component supply tape TP is attached between the sprocket 54 of the tape feeder 5 and the tape support member 56. In this manner, two component supply reels 7 can be mounted on one tape feeder 5. The mounting of the component supply reel 7 on the tape feeder 5 indicates that the tip of the component supply tape TP pulled out from the component supply reel 7 arranged on the reel holder 6 is mounted on the tape feeder 5.

In such a configuration, when the components of the component supply tape TP of the component supply reel 7 disposed at the use position Lu are used up out of the two component supply reels 7 mounted on the tape feeder 5, they are disposed at the standby position Lw. The component supply tape TP of the component supply reel 7 is loaded and used for component mounting. After one of the two component supply reels 7 is used up in this way, the operator puts another component supply reel 7 supplied from the component storage 81 into the tape feeder 5 and waits. I can leave it to you. Specifically, the operator
-Remove the component supply reel 7 from which the component has been cut from the use position Lu-Move the component supply reel 7 used for component mounting from the standby position Lw to the use position Lu-Place another component supply reel 7 at the standby position Lw The other component supply reel 7 is attached to the tape feeder by sequentially executing the procedure of mounting the tip of the component supply tape TP pulled out from the other component supply reel 7 between the sprocket 54 and the tape support member 56. 5 (mounting work).

FIG. 4 is a block diagram showing an example of a component mounting system according to the present invention. The component mounting system 100 includes a component mounting machine 1, a component storage 81 for storing a component supply reel 7 used in the component mounting machine 1, and a production plan management device 82 for managing component mounting in the component mounting machine 1. And a component supply management device 9 that manages the supply of components to the component mounting machine 1.

The parts storage 81 stores a large number of parts supply reels 7 in a predetermined storage location. The component storage 81 has a supply port for supplying the component supply reel 7 and a return port for receiving the component supply reel 7. Then, the parts storage 81 discharges the parts supply reel 7 from the storage location to the supply port according to the request from the parts supply management device 9 or the operator, and the parts supply reel 7 returned to the return port by the operator is stored in the storage location. store.

The production plan management device 82 is a server computer and manages the component mounter 1 based on a production plan Pp for producing a component mounting board by mounting components on the board B. Specifically, the production plan management device 82 creates board data indicating a procedure for mounting components on the board B based on the production plan Pp, and transmits the board data to the component mounting machine 1. Then, the component mounter 1 mounts the component on the board B according to the procedure indicated by the received board data.

The parts supply management device 9 is a server computer and includes a control unit 91, a storage unit 92, an ID reader 93, a user interface 94, and the like. The control unit 91 includes a CPU (Central Processing Unit), a RAM (Random Access).
The processor is composed of a memory (ROM) and a read only memory (ROM), and an acquisition unit 911, a prediction unit 912, a setting unit 913, and a determination unit 914 are built therein by executing a predetermined component supply management program. These operations will be described in detail later.

The storage unit 92 is an HDD (Hard Disk Drive) and stores the production plan Pp acquired from the production plan management device 82. Further, the storage unit 92 stores use history information H (FIG. 5) in which the use history of the component supply reel 7 is associated with the reel ID 73 of the component supply reel 7. Here, FIG. 5 is a diagram schematically illustrating an example of usage history information of the component supply reel. As shown in FIG. 5, in the usage history information H, the remaining number of components stored in the component supply reel 7, the type of tape feeder (used feeder) in which the component supply reel 7 is used, and the location of the component supply reel 7 are shown. , Associated with the reel ID 73.

Specifically, the type of tape feeder is managed based on the difference in the exposure method of parts. In other words, there are two methods for exposing parts: a method of opening the cover tape as described above, and a method of recovering the cover tape to the recovery mechanism while peeling the cover tape from the carrier tape as disclosed in Japanese Patent Application Laid-Open No. 2017-143225. Is at least present. Therefore, the type of the tape feeder in which the component supply reel 7 is used is associated with the reel ID 73 of the component supply reel 7.

Also, there are two places for the parts supply reel 7. That is, when the target component supply reel 7 is mounted on the component supply unit 25, the mounting location of the component supply reel 7 on the feeder mounting carriage 4 is associated with the reel ID 73, and the target component supply reel 7. Is stored in the component storage 81, the storage location of the component supply reel 7 is associated with the reel ID 73.

According to such a configuration, the component supply reel 7 is identified from the usage history (the number of remaining components, the feeder used, the location, etc.) of the component supply reel 7 (component storage member) that stores components mounted on the board B. The use history information H associated with the reel ID 73 (identifier) can be used. That is, by referring to the use history information H, the use history of the reel ID 73 can be confirmed from the reel ID 73 of the component supply reel 7.

Referring back to FIG. The ID reader 93 is a bar code reader and is used to read the reel ID 73 and the component ID 74 attached to the component supply reel 7. The ID reader 93 may be a portable type that communicates with the control unit 91 wirelessly, or may communicate with the control unit 91 by wire. Further, the user interface 94 is configured by, for example, a touch panel display, a speaker, and the like, and accepts an input operation from the operator or notifies the operator. In particular, the user interface 94 functions to display the usage history information H of FIG.

The component mounter 1 includes a control unit 18 in addition to the mechanical configuration shown in FIG. The control unit 18 is a processor composed of a CPU, a RAM, and a ROM, and executes control so that component mounting on the board B is executed according to the procedure shown in the board data received from the production plan management device 82. . In particular, the control unit 18 also functions to manage the remaining number of components in the component supply reel 7 mounted on the tape feeder 5.

FIG. 6 is a flowchart showing an example of remaining component number management executed by the control unit of the component mounter. This flowchart shows the total number of remaining parts (in other words, the total number of parts held on the reel holder 6 corresponding to the tape feeder 5), which is the total number of parts remaining on the two parts supply reels 7 mounted on the tape feeder 5. ) And the remaining number of components of the component supply reel 7 arranged at the use position Lu, and is executed for each tape feeder 5 in parallel with component mounting. In step S 101, it is confirmed whether the tape feeder 5 has supplied a component to the component supply position 50. When the supply of parts is confirmed (“YES” in step 101), the total number of remaining parts is decremented (step S102). In step S102, the remaining number of components on the component supply reel 7 used for component supply by the tape feeder 5 is notified to the component supply management device 9 together with the reel ID 73 of the component supply reel 7, and the component supply management device 9 The remaining part number associated with the reel ID 73 is updated with the usage history information H.

In step S103, it is confirmed whether the component supply reel 7 being used for component supply out of the two component supply reels 7 has been used up. If the part has not been used up and no part has run out (if “NO” in step S103), the process returns to step S101. Whether or not a part has been used up can be determined based on an appropriate standard. For example, when an operation for sucking a component supplied by the tape feeder 5 is executed, if it is not possible to confirm the suction / holding of the component, it is determined that a suction error has occurred. Therefore, when it is confirmed that a plurality of suction errors have occurred successively, it can be determined that the part has been used up. Alternatively, when it is confirmed that the number of remaining parts of the component supply reel 7 arranged at the use position Lu has become zero, it can be determined that the parts have been used up. On the other hand, if a component has run out (“YES” in step S103), the control unit 18 notifies the control unit 91 of the component replenishment management device 9 of the occurrence of component out (step S104). Notifies the operator through the user interface 94 of the execution of the mounting operation. In step S104, the control unit 18 causes the tape feeder 5 to execute the loading in steps S12 to S13 in FIG. 2, and uses the next component supply reel 7 for component supply.

In step S105, by confirming the acquisition of the reel ID 73 and the component ID 74 (hereinafter, appropriately referred to as “reel ID 73 etc.”) of the component supply reel 7 to be newly mounted, the operator performs the component supply reel 7 mounting operation. Grasp That is, the operator reads the reel ID 73 and the like of the component supply reel 7 with the ID reader 93 and then mounts the component supply reel 7 on the tape feeder 5 (mounting operation). At this time, the reel ID 73 and the like are transmitted from the component supply management device 9 to the control unit 18 of the component mounter 1.

When the acquisition of the reel ID 73 or the like cannot be confirmed (when “NO” in step S105), the control unit 18 confirms whether the tape feeder 5 has supplied the component to the component supply position 50 (step S106). If the supply of the component is not confirmed (“NO” in step S106), the process returns to step S105. If the supply of the component is confirmed (“YES” in step S106), the total number of remaining parts is decremented. (Step S107). In step S107, the remaining number of components on the component supply reel 7 used for component supply by the tape feeder 5 is notified to the component supply management device 9 together with the reel ID 73 of the component supply reel 7, and the component supply management device 9 The remaining part number associated with the reel ID 73 is updated with the usage history information H.

In step S108, it is confirmed whether or not the total number of remaining parts is equal to or less than the threshold number (here, the threshold number is an integer of 1 or more). If the total number of remaining parts is not less than the threshold number (if “NO” in step S108), the process returns to step S105. On the other hand, when the total number of remaining parts is equal to or less than the threshold number (in the case of “YES” in step S108), the control unit 18 notifies the control unit 91 of the component supply management device 9 to issue a remaining number warning (step S108). S109), the process returns to step S105. Upon receiving the notification in step S109, the control unit 91 executes a remaining number warning through the user interface 94. This remaining number warning is for the operator to immediately perform the mounting operation because the total number of remaining parts for the target tape feeder 5 has decreased.

If acquisition of the reel ID 73 or the like is confirmed in step 105 (“YES” in step S105), the total number of remaining parts is updated (step S110). Specifically, the remaining number of parts is updated by acquiring the remaining number of parts indicated by the usage history information H for the acquired reel ID 73 from the parts supply management device 9 and adding it. Then, the process returns to step S101. At this time, if the acquisition of the reel ID 73 or the like is confirmed in a situation where the remaining number warning is generated, the remaining number warning is canceled together with the update of the total number of remaining parts. These steps S101 to S110 are executed until the use of the tape feeder 5 in the component mounting is finished.

As described above, when the component supply reel 7 has run out due to the component mounting in the component mounting machine 1, the operator performs a replenishment operation for replenishing the component by the mounting operation of the component supply reel 7. There is a need. Therefore, the component supply management device 9 sets the execution time (mounting time) of the mounting work to be performed in parallel with component mounting on the component mounting machine 1. In particular, the mounting time is set so that the mounting work can be collectively performed on the plurality of tape feeders 5 in one replenishment work.

FIG. 7 is a flowchart showing a first example of setting of the mounting time executed by the parts supply management device. This flowchart is executed by the acquisition unit 911, the prediction unit 912, and the setting unit 913 of the control unit 91. In step S 201, the acquisition unit 911 acquires the production plan Pp from the production plan management device 82 and stores it in the storage unit 92. In step S202, when the component mounter 1 is caused to execute the production plan Pp, a plurality of periods (mountable periods) during which the mounting operation can be performed on the tape feeder 5 (mountable period) Each of (Nt) tape feeders is predicted by the prediction unit 912 (where Nt is an integer of 2 or more).

That is, as described with reference to FIG. 3, after one of the two component supply reels 7 mounted on the tape feeder 5 is used up by the sprocket 57 and is used up, The component supply tape TP from the component supply reel 7 is automatically engaged with and sent to the sprocket 57, so that the component supply is continued. The operator can execute a mounting operation of mounting another component supply reel 7 on the tape feeder 5 while the component supply is continued in this way. Therefore, the time when one of the two component supply reels 7 is used up is calculated as the start time of the mountable period. On the other hand, as described with reference to FIG. 6, after one component supply reel 7 has been used up, a remaining number warning is notified when the total number of remaining parts falls below the threshold number. It is preferable to perform the mounting operation. Therefore, the time when the total number of remaining parts becomes the threshold number (that is, the time when the remaining number warning is notified) is calculated as the end time of the mountable period.

It should be noted that the change in the number of remaining parts of the parts supply reel 7 mounted on the tape feeder 5 can be predicted based on the usage history information H and the production plan Pp. That is, the remaining component count (initial component remaining count) stored when the target component supply reel 7 is attached to the component supply reel 7 is associated with the reel ID 73 of the component supply reel 7 in the usage history information H. It can be acquired by referring to the number of remaining parts. Then, the number of remaining parts of the component supply reel 7 can be calculated by subtracting the number of times the parts of the component supply reel 7 are supplied from the initial number of remaining parts in the production plan Pp. Also in the flowchart shown below, the number of remaining parts of the component supply reel 7 is calculated in the same manner by appropriately referring to the use history information H and the production plan Pp.

FIG. 8 is a diagram showing an example of the calculation result of the wearable period executed according to the flowchart of FIG. In the example of FIG. 8, an example of setting the mounting time for five (Nt = 5) tape feeders 5A to 5E is shown. However, the number Nt of the target tape feeders 5 is naturally not limited to the five in this example. In FIG. 8, the difference in state is shown by the shade of the hatching, and the darkest hatching period corresponds to a period in which no part breakage occurs in both of the two parts supply reels 7, and the next darkest hatching The period corresponds to a period from when a component is cut out in one component supply reel 7 until the remaining number warning is notified, and the lightest hatching period corresponds to a period after the remaining number warning is notified. .

According to the example in FIG. 8, for the

tape feeders

5A, 5B, 5C, and 5D, one component supply reel 7 runs out at time t1a, t1b, t1c, and t1d. Further, a remaining number warning is notified to the

tape feeders

5A and 5B at times t2a and t2b, respectively. As a result, in step S202, it is calculated that the mounting work can be performed on the

tape feeders

5A, 5B, 5C, and 5D in the mounting possible periods Ta, Tb, Tc, and Td, respectively.

In step S203 of FIG. 7, among the plurality (Nt) of tape feeders 5, Nc candidate feeders in which the mounting possible periods Ta, Tb, Tc, and Td overlap are specified by the setting unit 913 (here, Nc is an integer of 2 or more and Nt or less). In particular, among Nt tape feeders 5, candidate feeders are specified such that other tape feeders 5 can be installed in the same period Ta during which the tape feeder 5 A in which the remaining number warning is first notified. . In this example, specifically, in the overlap period To, the mountable periods Ta, Tb, and Td overlap, so three (Nc = 3)

tape feeders

5A, 5B, and 5D are identified as candidate feeders. Is done.

In step S204, the setting unit 913 sets the mounting time ts so as to overlap the mounting possible periods Ta, Tb, Td of the

candidate feeders

5A, 5B, 5D. Specifically, the start time t1b of the overlap period To in which the mountable periods Ta, Tb, and Td overlap, in other words, one part supply reel 7 of the

candidate feeders

5A, 5B, and 5D is finally cut out. The time t1b to be set is set as the mounting time ts. In this way, the mounting time ts is made common to the three

candidate feeders

5A, 5B, and 5D, and it is possible to execute the mounting work on these

candidate feeders

5A, 5B, and 5D in a single replenishment operation. Become. Note that the mounting time ts is not necessarily coincident with the time t1b, and may be set after the time t1b. That is, the wearing time ts can be set to an appropriate time that overlaps the overlapping period To.

Furthermore, the parts supply management device 9 of the present embodiment determines the execution mode of the mounting work for the

candidate feeders

5A, 5B, and 5D thus identified based on the production plan Pp. Here, the execution mode of the mounting work is a concept including whether or not to perform the mounting work and which component supply reel 7 is used in the mounting work.

FIG. 9 is a flowchart showing a first example of mounting mode determination executed by the component supply management device. This flowchart is executed by the determination unit 914 of the control unit 91. In step S301, the variable I for individually identifying the tape feeder 5 specified as the candidate feeder is reset to zero, and in step S302, the variable I is incremented.

In step S303, for the I-th tape feeder 5, the total number of remaining parts at the start time of the mountable period is calculated based on the production plan Pp and the usage history information H. In step S304, the number of parts to be supplied in the target period from the start of the period in which the I-th tape feeder 5 can be mounted to the end of the production plan Pp is calculated based on the production plan Pp. In step S305, if the mounting operation is not executed in the mounting time ts set according to the flowchart of FIG. 7, it is determined whether or not a component is out of the target period, that is, the remaining total number calculated in step S303. It is determined whether or not the number of parts to be supplied calculated in step S304 is larger.

If it is determined that the component is out (if “YES” in step S305), the component will be out unless the mounting operation is executed during the mounting time ts. Therefore, the I-th tape feeder 5 is selected as the target of the mounting work according to the mounting time ts (step S306), and the process proceeds to step S308. On the other hand, if it is determined that no parts are cut out (“NO” in step S306), no parts are cut out even if the mounting operation is not executed during the mounting time ts. Therefore, the I-th tape feeder 5 is removed from the target of the mounting work according to the mounting time ts (step S307), and the process proceeds to step S308.

In step S308, it is determined whether or not the variable I matches the maximum value Ix. Here, the maximum value Ix is the number of tape feeders 5 specified as candidate feeders. Then, steps S302 to S307 are repeated until the variable I coincides with the maximum value Ix, whereby the mounting work execution mode (whether or not the mounting work is executed) is performed for all the tape feeders 5 identified as candidate feeders. Is determined. In addition, the determination unit 914 notifies the operator via the user interface 94 so that the mounting operation for the tape feeder 5 that is the target of the mounting operation is executed at the mounting time ts.

FIG. 10 is a diagram schematically showing the contents of the calculation executed in the flowchart of FIG. 9 in a timing chart. In particular, an example corresponding to the tape feeder removed from the mounting work target is shown in the flowchart of FIG. Yes. In the timing chart of FIG. 10, the total number of remaining parts for the tape feeder 5 is the vertical axis and the time is the horizontal axis, and the remaining parts due to the execution of the production plan Pp for sequentially producing four different types of component mounting boards B1 to B4. The change in the total number is shown.

The rate at which components are used (the number of components supplied per unit time) varies depending on the types of boards B1 to B4. Therefore, every time the boards B1 to B4 to be produced are changed, the component usage rate, that is, the inclination of the timing chart changes. Then, at time t1, when a component breakage occurs in the preceding component supply reel 7 used first out of the two component supply reels 7 mounted on the tape feeder 5, the mountable period T starts. Further, after time t1, the subsequent component supply reel 7 to be used later is used out of the two component supply reels 7.

In step S303 of FIG. 9 described above, the total number of remaining parts Qt at the start time t1 of the mountable period T is predicted based on the production plan Pp and the usage history information H. This remaining part total number Qt corresponds to the number of parts stored in the subsequent part supply reel 7. Here, the subsequent component supply reel 7 is the component supply reel 7 placed at the standby position Lw in FIG. Further, it is assumed that the preceding component supply reel 7 at the use position Lu has not been discharged immediately after the component has run out, and the loading of the subsequent component supply reel 7 by the sprocket 54 has not started.

In step S304, from the start time t1 of the mountable period T to the end time tf of the production plan Pp, the number Qu of parts scheduled to be supplied by the tape feeder 5 is predicted based on the production plan Pp. In step S305, the presence or absence of parts is predicted based on whether the total number of remaining parts Qt is less than the number of parts to be supplied Qu. In the example of FIG. 10, since the total number of remaining parts Qt is equal to or greater than the number of parts to be supplied Qu, it is determined that no parts will run out (“NO” in step S305), and the corresponding tape feeder 5 is removed from the mounting work target. It is removed (step S307).

In addition to determining whether the parts are out of stock at the end of the production plan Pp, the type of parts to be supplied by the tape feeder 5 is changed when the type of the component mounting board B is switched during the continuation of the production plan Pp. The same management can be executed. In other words, if the preceding component supply reel 7 does not run out before switching the type of the component mounting board B, the subsequent component supply reel 7 may be similarly excluded from the mounting work target.

By the way, at the production site of the component mounting board, not all the components of the component supply reel 7 are used up every time the board is produced, and a used component supply reel 7 in which some components are used can be generated. As a result, there are cases where a plurality of component supply reels 7 including new and used ones can be used for the mounting work on the candidate feeder 5, and the components can be removed by an appropriate component supply reel 7 while confirming the usage history of the component supply reel 7. There is a need to replenish. Next, an embodiment that can suitably meet such needs will be described.

FIG. 11 is a flowchart showing a second example of the mounting mode determination executed by the component supply management apparatus, and it is determined which component supply reel 7 is mounted on the tape feeder 5 in the mounting operation according to the mounting time ts. To do. This flowchart is executed by the determination unit 914 for each tape feeder 5 specified as a candidate feeder. However, since the contents executed for each tape feeder 5 are the same, the contents executed for one tape feeder 5 will be described.

In step S401, it is determined whether there is a used component supply reel 7 that can be used in the mounting operation to the tape feeder 5 specified as the candidate feeder. Specifically, it is determined based on the usage history information H whether the used component supply reel 7 storing the same type of component as the component to be supplied by the tape feeder 5 is stored in the component storage 81. If the corresponding used component supply reel 7 does not exist (in the case of “NO” in step S401), a new component supply reel 7 (one target storage member) is attached to the tape feeder 5 at a time ts. It is determined to be mounted by the mounting work according to the (step S402).

On the other hand, when the corresponding used component supply reel 7 (target storage member) exists (in the case of “YES” in step S401), the used component supply reel 7 is set to the number of remaining components indicated in the usage history information H. Based on the ascending order (step S403). Then, the variable J indicating the sort order is reset to zero (step S404), and the variable J is incremented (step S405).

In step S406, the total number of remaining parts when the J-th part supply reel 7 is mounted at the mounting time ts is calculated. In step S407, the number of parts to be supplied is calculated in the target period from the mounting time ts to the end of the production plan Pp. Then, in step S408, if the J-th component supply reel 7 is mounted at the mounting time ts, whether or not the component runs out during the target period, that is, the total number of remaining components calculated in step S406 is determined in step S407. It is determined whether or not the calculated number of parts to be supplied is large.

If it is determined that no component breakage occurs (in the case of “NO” in step S408), the J-th component supply reel 7 (one target storage member) is the target tape in the mounting operation according to the mounting time ts. It is determined to be attached to the feeder 5 (step S409). On the other hand, if it is determined that the part is out (if “YES” in step S408), the process proceeds to step S410, and it is determined whether or not the variable J matches the maximum value Jx. Here, the maximum value Jx is the number of used component supply reels 7 (target storage members) that can be used. Steps S406 to S408 are repeated until the variable J reaches the maximum value Jx.

In other words, if there is a component supply reel 7 (one target storage member) that is judged not to be out of components in step S408 among the Jx used component supply reels 7, this component supply reel 7 is mounted. It is determined to be mounted on the target tape feeder 5 by the mounting operation according to the time ts (step S409). On the other hand, when the corresponding component supply reel 7 does not exist, it is determined that the new component supply reel 7 (one target storage member) is mounted on the target tape feeder 5 by the mounting operation according to the mounting time ts ( Step S402). Further, the determining unit 914 notifies the operator via the user interface 94 so that the component supply reel 7 determined to be used in step S402 or S409 is mounted on the tape feeder 5 by the mounting operation at the mounting time ts.

FIG. 12 is a diagram schematically showing the contents of the calculation executed in the flowchart of FIG. 11 in a timing chart. The notation of FIG. 12 is the same as that of FIG. At time t 1, when a component break occurs in the preceding component supply reel 7 used first out of the two component supply reels 7 mounted on the tape feeder 5, the mountable period T starts. After time t1, the subsequent component supply reel 7 used later is used out of the two component supply reels 7.

Further, in the example of the figure, as the component supply reel 7 that can be mounted on the target tape feeder 5 in the mounting operation according to the mounting time ts, three

component supply reels

7A, 7B, 7C (different component storage numbers) are provided. A plurality of target storage members). Among these, the component supply reel 7A is a new component supply reel 7, and each of the component supply reels 7B and 7C is a used component supply reel 7. In particular, in FIG. 12, the change in the total number of remaining components when the

component supply reels

7A, 7B, and 7C are respectively mounted in the mounting operation at the mounting time ts is shown after the mounting time ts.

Incidentally, at the mounting time ts, the total number of remaining parts increases discontinuously with the execution of the mounting work. However, the component supply reel 7 used for component mounting before and after the mounting time ts is the subsequent component supply reel 7 described above. The use of the component mounting of the

component supply reels

7A, 7B, and 7C to be mounted at the mounting time ts is started after the time t3 when the subsequent component supply reel 7 causes the component to run out.

In step S403 of FIG. 11, these are sorted in the order of the

component supply reels

7C, 7B, 7A. In the flowchart of FIG. 11, in the loop with the variable J being 1, the remaining total number Qtc when the component supply reel 7C is mounted at the mounting time ts is predicted based on the production plan Pp (step S406). In addition, the scheduled supply number Qu from the mounting time ts to the end time tf of the production plan Pp is predicted based on the production plan Pp (step S407). Then, based on whether or not the total number of remaining parts Qtc is less than the number of parts to be supplied Qu, it is determined whether or not a part has run out (step S408). Since the total number of remaining parts Qtc is less than the number of parts to be supplied Qu, it is determined that the parts will run out when the parts supply reel 7C is mounted, and the process returns to step S405.

In the loop where the variable J is 2, steps S406 to S408 are executed for the component supply reel 7B. When the component supply reel 7B is mounted at the mounting time ts, the remaining component total number Qtb is equal to or greater than the scheduled supply component number Qu, and it is determined in step S408 that there is no component cut (NO). As a result, it is determined that the component supply reel 7B (one component storage member) is used for the mounting operation at the mounting time ts (step S409).

In addition to determining whether the parts are out of stock at the end of the production plan Pp, the type of parts to be supplied by the tape feeder 5 is changed when the type of the component mounting board B is switched during the continuation of the production plan Pp. The same management can be executed. That is, even if the used component supply reel 7 is mounted at the mounting time ts before the type of the component mounting board B is switched, the used component supply reel 7 is similarly used for mounting work. Then you may decide.

According to the embodiment described above, the control unit 91 mounts another component supply reel 7 for storing a component on the tape feeder 5 after the component supply reel 7 is cut during the production plan Pp. The mounting mode determination (determination process) for determining another component supply reel 7 to be used for the above is executed. In this mounting mode determination, when there are a plurality of

component supply reels

7A, 7B, and 7C having different component storage numbers as another component supply reel 7 that can be used for the mounting operation, a plurality of

component supply reels

7A, 7B, It is determined that one component supply reel 7B selected based on the remaining component count (use history) of each of 7C is used for the mounting operation. Therefore, it is possible to select an appropriate part supply reel 7B based on the number of remaining parts and use it for the production plan Pp. A number of parts can be replenished.

Particularly, the usage history of the usage history information H referred to in the mounting mode determination includes the number of parts stored in the part supply reel 7 identified by the corresponding reel ID 73 (identifier) as the remaining part number. In the mounting mode determination, one part supply reel 7B is determined based on the number Qu of parts scheduled to be supplied by the tape feeder 5 according to the production plan Pp and the remaining number of parts of each of the plurality of

part supply reels

7A, 7B, 7C. select. In such a configuration, an appropriate part supply reel 7B can be selected and used for the production plan Pp based on the remaining number of parts, and the used part supply reel 7 can be used efficiently while being used for the production plan Pp. An appropriate number of parts can be supplied.

Also, a mounting time ts (first reference time) indicating the execution timing of the mounting work is set, and in the mounting mode determination, one component supply reel 7B used in the mounting work executed corresponding to the mounting time ts is selected. Is done. Thereby, in the mounting work according to the mounting time ts, it is possible to use one appropriate component supply reel 7B selected based on the remaining number of components.

Further, in the mounting mode determination, the number of parts Qu to be supplied by the tape feeder 5 from the mounting time ts to the end time tf of the production plan Pp according to the production plan Pp, and each of the parts supply

reels

7A, 7B, 7C. Based on the remaining number, one component supply reel 7B is selected. In such a configuration, it is possible to select one component supply reel 7B having a remaining number of components suitable for component mounting from the mounting time ts to the end time tf of the production plan Pp and use it for the mounting operation.

By the way, it is necessary to repeatedly perform the mounting operation every time a part runs out. Therefore, for example, two mounting times ts may be set in advance. Furthermore, the execution mode of the mounting operation at the first mounting time ts can be managed according to the number of parts scheduled to be supplied at the first and second mounting times ts (third example of mounting mode determination). . Subsequently, such an embodiment will be described.

FIG. 13 is a flowchart showing a second example of setting the mounting time executed by the parts supply management device. This flowchart is executed by the acquisition unit 911, the prediction unit 912, and the setting unit 913 of the control unit 91. Steps S201 to S204 are executed in the same manner as the first example of the wearing time setting described above with reference to FIG. As a result, the first mounting time ts1 is set similarly to the above-described mounting time ts.

Next, in step S205, the setting unit 913 determines whether the second mounting time ts2 has been set. Here, since it is not set, “NO” is determined in step S205, and the prediction unit 912 receives a new component supply reel 7 for each tape feeder 5 specified as a candidate feeder at the first mounting time ts1. Is assumed to be attached (step S206). Also, assuming this assumption, steps S201 to S204 are executed to set the second mounting time ts2. In step S205, it is determined that the second mounting time ts2 has been set (YES), and the process ends.

Note that the method of setting the second mounting time ts2 is not limited to this example. For example, without assuming the mounting of a new component supply reel 7 as in step S206, the time when a certain period (for example, 60 minutes) has elapsed from the first mounting time ts1 is set as the second mounting time ts2. You may do it.

The third example of the mounting mode determination according to the first and second mounting times ts1 and ts2 set in this way can be executed according to the same flowchart as FIG. However, in step S407, the number of parts to be supplied between the first and second mounting times ts1 and ts2 by the tape feeder 5 to be mounted is calculated. Further, in step S408, based on the calculation result in step S407, it is determined whether a remaining number warning is generated, not a component shortage. This will be described with reference to FIG.

FIG. 14 is a diagram schematically showing, in a timing chart, the contents of the calculation executed in the third example of the mounting mode determination executed by the component supply management device. The notation of FIG. 14 is the same as that of FIG. At time t 1, when a component break occurs in the preceding component supply reel 7 used first out of the two component supply reels 7 mounted on the tape feeder 5, the mountable period T starts. After time t1, the subsequent component supply reel 7 used later is used out of the two component supply reels 7.

Further, in the example of the figure, as the component supply reel 7 that can be mounted on the target tape feeder 5 in the mounting operation corresponding to the first mounting time ts1, three

component supply reels

7A and 7B having different component storage numbers are provided. , 7C (a plurality of target storage members). Among these, the component supply reel 7A is a new component supply reel 7, and each of the component supply reels 7B and 7C is a used component supply reel 7. In particular, in FIG. 12, the change in the total number of remaining components when the

component supply reels

7A, 7B, and 7C are respectively mounted in the mounting operation at the first mounting time ts1 is shown after the first mounting time ts1.

Then, in the flowchart of FIG. 11, in the loop with the variable J being 1, the number of parts to be supplied Qu from the first mounting time ts1 to the second mounting time ts2 is predicted based on the production plan Pp (step S407). Then, it is determined whether or not the remaining number warning is generated based on whether or not the remaining part total number Qtc is equal to or less than the sum (second required number) of the scheduled part number Qu and the threshold number Qh (predetermined number) (step S408). ). The threshold number Qh is the threshold number used as a reference for executing the remaining number warning in step S108 of FIG. Here, since the total number of remaining parts Qtc is equal to or less than the sum of the number of parts to be supplied Qu and the threshold number Qh, it is determined that a remaining number warning is generated when the part supply reel 7C is mounted, and the process returns to step S405.

In the loop where the variable J is 2, steps S406 to S408 are executed for the component supply reel 7B. When the component supply reel 7B is mounted at the first mounting time ts1, the remaining component total number Qtb is larger than the sum of the scheduled component number Qu and the threshold number Qh, so no remaining number warning is generated in step S408 (NO). It is judged. As a result, it is determined that the component supply reel 7B (one component storage member) is used for the mounting operation at the first mounting time ts1 (step S409).

Also in this embodiment, mounting mode determination (determination processing) for determining another component supply reel 7 used for mounting work is executed. In this mounting mode determination, when there are a plurality of

component supply reels

Further, after the first mounting time ts1, a second mounting time ts2 indicating the timing of the mounting work is set. In the mounting mode determination, the number of parts Qu to be supplied by the tape feeder 5 from the first mounting time ts1 to the second mounting time ts2 according to the production plan Pp, and the plurality of

component supply reels

7A, 7B, 7C, respectively. One component supply reel 7B is selected based on the remaining component number. Therefore, it is possible to select one component supply reel 7B having an appropriate number of remaining components for component mounting from the first mounting time ts1 to the second mounting time ts2 and use it for the mounting operation.

As described above, the mounting mode of the component supply reel 7 according to the mounting time ts can be determined in various modes. Then, it is possible to cause the operator to perform the mounting operation of the component supply reel 7 according to the determined mounting mode. At this time, the parts supply management device 9 can execute various operations for assisting the operator's mounting work.

FIG. 15 is a flowchart showing an example of control for assisting the operator's mounting work. This flowchart is executed by the control unit 91 of the component supply management device 9. When the acquisition of the reel ID 73 by the ID reader 93 is confirmed (“YES” in step S501), the location of the tape feeder 5 that is the target of the mounting operation of the component supply reel 7 indicated by the reel ID 73 is notified (step S502). ). Such notification may be performed by displaying the location of the tape feeder 5 on the user interface 94, or a command is transmitted to the control unit 18 of the component mounter 1 to light a lamp or the like provided on the tape feeder 5. You may go by.

Then, the control unit 91 determines whether or not the component supply reel 7 indicated by the reel ID 73 is used based on the usage history information H (step S503). If it is not used (if “NO” in step S503), the process proceeds to step S505. On the other hand, when it is used (in the case of “YES” in step S503), the control unit 91 transmits a command to the control unit 18 of the component mounter 1 in step S504, and is a tape that is the target of the mounting work. After the loading by the tape feeder 5 other than the feeder 5 is prohibited, the process proceeds to step S505.

In step S505, the control unit 91 determines that the remaining number of components on the component supply reel 7 (mounted component supply reel 7) that has been previously mounted on the tape feeder 5 and is being used for component supply is the component to be mounted. Based on the usage history information H, it is determined whether the number of remaining parts of the supply reel 7 (part supply reel 7 to be mounted) is larger. When the remaining number of parts on the mounted component supply reel 7 is equal to or less than the remaining number of parts on the mounted component supply reel 7 (in the case of “NO” in step S505), the flowchart of FIG.

On the other hand, when the number of remaining components on the mounted component supply reel 7 is larger than the remaining number of components on the mounted component supply reel 7 (in the case of “YES” in step S505), the control unit 91 (particularly the determination unit 914). Determines to execute steps S506 to S509. That is, in step S506, the control unit 91 transmits a command to the control unit 18 of the component mounter 1 to execute the non-stop insertion / removal mode. This non-stop insertion / removal mode is a mode in which the supply of parts by the target tape feeder 5 is prohibited for a corresponding period, and the mounting of the parts supplied by the tape feeder 5 is changed after the corresponding period.

Then, the control unit 91 guides the operator to replace the component supply reel 7 via the user interface 94 (step S507). Upon receiving this guidance, the operator removes the component supply tape TP of the component supply reel 7 from the tape feeder 5 while moving the mounted component supply reel 7 from the use position Lu to the standby position Lw. It is sandwiched between the tape support member 56. Further, the operator loads the component supply tape TP of the component supply reel 7 to be mounted on the tape feeder 5. When the operator inputs to the user interface 94 that the replacement of the component supply reel 7 has been completed in this way (“YES” in step S508), the control unit 91 transmits a command to the control unit 18 of the component mounter 1, The stop insertion / removal mode is canceled (step S509).

FIG. 16 is a diagram schematically showing the contents of the calculation executed in the flowchart of FIG. 15 in a timing chart. The notation of FIG. 16 is the same as that of FIG. At time t1, when a component out of the two component supply reels 7 mounted on the tape feeder 5 occurs in the preceding component supply reel 7, use of the subsequent component supply reel 7D is started.

In the example of FIG. 16, replacement of the component supply reel 7 is executed in the mounting operation at the mounting time ts, and the component supply reel 7 used for component supply is supplied from the mounted component supply reel 7D to the component to be mounted. It is switched to the reel 7E. When the component supply reel 7E runs out at time t4, the use of the component supply reel 7D is started, and the remaining number of components on the component supply reel 7D is reduced to the threshold number at time t5.

In other words, the determination unit 914 uses the component supply operation for the component supply reel 7E when the component storage number of another component supply reel 7E is smaller than the component storage number of the component supply reel 7D being used for the component supply operation at the mounting time ts. It is determined that the mounting operation is executed while switching the component supply reel 7 to be switched to another component supply reel 7E. In such a configuration, compared to the case where the component supply reel 7E is mounted without performing such switching, the mounting possible period T (FIG. 16) generated after the mounting work corresponding to the mounting time ts can be secured, and the mounting is performed. A time margin that can be used for the mounting work to be executed according to the possible period T can be created.

Further, when the used component supply reel 7 is selected for use in the mounting operation, the control unit 91 prohibits loading by a tape feeder 5 other than the tape feeder 5 targeted for the mounting operation. In the tape feeder 5 where loading is prohibited, the tip of the component supply reel 7 at the standby position Lw stands still in a standby state between the sprocket 54 and the tape support member 56, so the operator can add a new component supply reel 7. Cannot perform the installation work to install. That is, the mounting of one component supply reel 7 to the tape feeder 5 other than the tape feeder 5 to be mounted is prohibited (loading is prohibited). In this way, it is possible to prevent the used component supply reel 7 from being erroneously mounted on the tape feeder 5 different from the mounting work target.

In addition, when the ID reader 93 acquires the reel ID 73 of the component supply reel 7, the control unit 91 notifies the operator of the tape feeder 5 to be mounted on the component supply reel 7 in the mounting operation. With such a configuration, it is possible to reliably mount the component supply reel 7 to be mounted on the appropriate tape feeder 5.

Thus, in this embodiment, the component mounting system 100 corresponds to an example of the “component mounting system” of the present invention, the component mounting machine 1 corresponds to an example of the “component mounting machine” of the present invention, and the component supply management device 9 corresponds to an example of the “part supply management device” of the present invention, the control unit 91 corresponds to an example of the “control unit” of the present invention, and the storage unit 92 corresponds to an example of the “storage unit” of the present invention. The component supply reel 7 corresponds to an example of the “component storage member” of the present invention, the reel ID 73 corresponds to an example of the “identifier” of the present invention, and the usage history information H is an example of the “use history information” of the present invention. The tape feeder 5 corresponds to an example of the “feeder” of the present invention, the mounting time ts or the mounting time ts1 corresponds to an example of the “first reference time” of the present invention, and the mounting time ts2 corresponds to the present invention. It corresponds to an example of “second reference time” and Over 93 corresponds to an example of the "identifier-acquiring portion" of the present invention, user interface 94 corresponds to an example of the "notification portion" in the present invention.

The present invention is not limited to the above embodiment, and various modifications can be made to the above without departing from the spirit of the present invention. For example, the usage history information H includes the type of the tape feeder 5 in which the component supply reel 7 is used as the usage history. Therefore, the following modifications may be added to the above-described mounting mode determination.

That is, as described above, as the tape feeder 5, the first type feeder that exposes the components by removing the cover tape from the carrier tape and recovering it to the recovery mechanism, and the second type that exposes the components by opening the cover tape. There is a feeder. Therefore, in this modified example of the mounting mode determination, it is prohibited to mount the component supply reel 7 having a history used for the component supply operation by the second type feeder in the first type feeder in the mounting operation.

That is, when the component supply reel 7 is mounted on the first type feeder, the tip of the cover tape needs to be peeled off from the carrier tape in order to attach the tip of the cover tape to the recovery mechanism. Therefore, a new part supply tape TP is usually provided with a leader part in which no parts are stored, and the cover tape of this reater part is attached to the recovery mechanism. On the other hand, the used parts supply tape TP having a history of use in the type 2 feeder does not have such a leader. Therefore, in order to mount this used part supply tape TP to the first type feeder, it is necessary to peel the cover tape from the carrier tape for attachment to the recovery mechanism, and the parts stored in the peeled part are useless. become. In contrast, by prohibiting the component supply reel 7 used for the component supply operation by the second type feeder from being mounted on the first type feeder in the mounting operation, it is possible to suppress waste of components.

Of course, various modifications different from such modifications are possible. For example, in the above embodiment, the timing for executing the mounting mode determination is not particularly described, but the mounting mode determination can be performed at various timings. Specifically, the mounting mode determination may be executed before the production plan Pp is started, or the mounting mode determination may be executed for the next mounting operation every time the mounting operation is executed.

Also, the number of component supply reels 7 that can be mounted on one tape feeder 5 is not limited to two, and may be three or more, for example.

Also, the type of feeder is not limited to a tape feeder, and may be a tray feeder or a stick feeder.

Further, it is not necessary to include all items (remaining parts, used feeders, and places) shown in FIG. 5 in the usage history information H, and these items may be omitted as appropriate.

Further, in the above embodiment, as shown in FIGS. 7 and 8, the case where the mounting work is collectively performed on the plurality of tape feeders 5 by one replenishment work is illustrated. However, even when the mounting operation is performed on one tape feeder 5 in one replenishment operation, the usage history of the component supply reel 7 to be mounted is confirmed based on the usage history information H. Thus, it is possible to select an appropriate component supply reel 7 for the mounting operation.
