Description

This specification discloses technology relating to a component management device and a component management method.

In the reel management system described in Patent Document 1, when an operator removes a reel that is in use from a feeder, the operator uses a reading device to read the feeder identification part of the feeder to which the reel is attached, and then uses the reading device to read the reel identification part of the reel. The management device then cancels the association between the feeder identification information of the read feeder identification part and the reel identification information of the read reel identification part. Specifically, the feeder identification information of the feeder is erased from the reel management information.

International Publication No. 2014/038051

When a first component that contains a component to be mounted on a board or a second component that is used together with the first component is stored in a storage device, there is a demand to delete combination information that indicates the combination of the first component and second component that was used before the storage.

In consideration of these circumstances, this specification discloses a component management device and a component management method that are capable of deleting combination information indicating the combination of a first component and a second component that was used before the first component or second component was stored in a storage device.

This specification discloses a member management device including a determination unit and a deletion unit. The determination unit determines whether a first member that contains a component to be mounted on a board or a second member used together with the first member will be stored in a storage device. When the determination unit determines that the first member or the second member will be stored, the deletion unit deletes combination information indicating the combination of the first member and the second member that was used before the storage.

This specification also discloses a member management method including a determination step and a deletion step. The determination step determines whether a first member that contains a component to be mounted on a board or a second member used together with the first member will be stored in a storage device. The deletion step deletes combination information indicating the combination of the first member and the second member that was used before the storage, when the determination step determines that the first member or the second member will be stored.

The above-mentioned component management device includes a judgment unit and a deletion unit. As a result, when a first component or a second component is stored in a storage device, the component management device can delete combination information indicating the combination of the first component and the second component that was used before the storage. What has been described above about the component management device can also be said about the component management method.

1 shows an example of a production facility to which a member management device 80 is applied. The production facility shown in Fig. 1 includes a substrate-related work line 10L, a receiving section 20, and a storage device 70. The storage device 70 includes a storage cabinet 30, a shelf 40, a dry box 50, and an oven 60.

1-1. Substrate work line 10L
In the substrate-related work line 10L, substrate-related work machines 10 perform a predetermined substrate-related work on a substrate 90. There is no limitation on the type and number of substrate-related work machines 10. As shown in Fig. 1, the substrate-related work line 10L of the present embodiment includes a plurality of (five) substrate-related work machines 10, including a printer 10a, a print inspection machine 10b, a component mounting machine 10c, a reflow oven 10d, and a visual inspection machine 10e, and the substrate 90 is transported in the above order by a substrate transport device.

The printer 10a prints solder at the mounting position of the component 91 on the board 90. The print inspection machine 10b inspects the printing condition of the solder printed by the printer 10a. The component mounting machine 10c mounts multiple components 91 on the board 90 on which the solder has been printed. There may be one component mounting machine 10c, or multiple component mounting machines 10c. When multiple component mounting machines 10c are provided, the multiple component mounting machines 10c can share the task of mounting multiple components 91 on the board 90.

The component mounting machine 10c is equipped with a component supplying device that supplies components 91 to be mounted on the board 90. The component supplying device can supply components 91 using, for example, a feeder 22a equipped with a reel 21a shown in FIG. 2A, a tray pallet 22b equipped with a tray 21b shown in FIG. 2B, or the like. The reel 21a has a carrier tape 21t that contains the components 91 wound around its main body 21a1. The feeder 22a holds the reel 21a rotatably. The tip of the carrier tape 21t is pulled out to a component removal section provided in the feeder 22a, and the components 91 are sequentially supplied. The reel 21a can supply relatively small components 91, such as chip components.

Components 91 are arranged on the tray 21b. The tray 21b can supply relatively large components 91, such as QFP (Quad Flat Package) and BGA (Ball Grid Array). The tray 21b supplies the components 91 in a state where they are mounted on a tray pallet 22b. The reflow furnace 10d heats the board 90 on which the components 91 are mounted by the component mounting machine 10c, melting the solder and performing soldering. The appearance inspection machine 10e inspects the mounting state of the components 91 mounted by the component mounting machine 10c.

In this way, the substrate-related work line 10L can use multiple (five) substrate-related work machines 10 to transport substrates 90 in sequence and perform production processes including inspection processes to produce substrate products. The substrate-related work line 10L can also be equipped with substrate-related work machines 10 such as a functional inspection machine, a buffer device, a substrate supply device, a substrate reversing device, a shield mounting device, an adhesive application device, and an ultraviolet ray irradiation device, as necessary.

The multiple (five) substrate-related operation machines 10 and the management device 19 that make up the substrate-related operation line 10L are arranged to be able to communicate with each other via a wired or wireless communication unit. The management device 19 controls the multiple (five) substrate-related operation machines 10 of the substrate-related operation line 10L and monitors the operating status of the substrate-related operation line 10L. The management device 19 stores various control data for controlling the multiple (five) substrate-related operation machines 10. The management device 19 transmits control data to each of the multiple (five) substrate-related operation machines 10. In addition, each of the multiple (five) substrate-related operation machines 10 transmits its operating status and production status to the management device 19.

1-2. Arrival section 20
For example, when the reel 21a arrives at the receiving section 20, the receiving operation described below is performed. Then, the reel 21a is, for example, stored in a storage case, loaded onto a transport vehicle, and transported to the storage facility 30. After being stored in the storage facility 30, the reel 21a is supplied to the substrate-related work line 10L as necessary.

As shown in FIG. 2A, the reel 21a is provided with an identification code 23a that can identify the reel 21a. The identification code 23a may be, for example, a sticker with a one-dimensional code, a two-dimensional code, or a wireless tag printed thereon. Specifically, when the reel 21a arrives at the receiving section 20, the worker issues the identification information using, for example, an item management device. The worker also uses a barcode reader or the like to read a barcode or the like attached to the reel 21a by the supplier (vendor). The worker can also obtain the item information from a database in which item information related to the reel 21a is registered. The worker uses the item management device to issue the identification code 23a that includes at least the identification information and the item information.

The worker attaches a sticker with an identification code 23a, which includes at least identification information, to the surface of the reel 21a, and places the reel 21a in a storage case. The worker loads the storage case containing the reel 21a onto a transport vehicle. For example, the transport vehicle can be towed by the worker. Alternatively, an unmanned transport vehicle capable of automatic travel can be used as the transport vehicle. The transport vehicle can also transport the reel 21a to the storage facility 30 without using a storage case. Alternatively, the worker can transport the reel 21a to the storage facility 30 without using a transport vehicle.

The worker can attach an identification code 23b that can identify the tray 21b to the tray 21b in the same manner as the reel 21a. As shown in FIG. 2B, the tray 21b is contained in a packaging bag, and the identification code 23b is attached to the packaging bag. The identification code 23b can also be attached to the tray 21b. For example, the identification code 23b is a sticker on which a one-dimensional code, a two-dimensional code, or a wireless tag is printed. The transport vehicle or the worker transports the tray 21b to the storage facility 30 in the same manner as the reel 21a.

As shown in FIG. 2A, feeder 22a is provided with identification code 24a that allows feeder 22a to be identified. As shown in FIG. 2B, tray pallet 22b is provided with identification code 24b that allows tray pallet 22b to be identified. Identification codes 23a and 24b can be, for example, stickers printed with one-dimensional codes, two-dimensional codes, or wireless tags. At least a portion of the work performed by the workers described above can be automated using a conveying device (e.g., a belt conveyor), an actuator (e.g., a robot arm), an item management device, or the like.

1-3. Storage 30
The storage 30 can store the first member 21, such as the reel 21a and the tray 21b, which accommodates the components 91 to be mounted on the substrate 90. The storage 30 can also store the second member 22, such as the feeder 22a and the tray pallet 22b, which is used together with the first member 21. The storage 30 can also store both the first member 21 and the second member 22. In this way, the storage 30 can take various forms as long as it can store at least one of the first member 21 and the second member 22. As shown in Figures 3A and 3B, the storage 30 of this embodiment is formed, for example, in an octagonal prism shape.

The storage facility 30 includes an entrance 30a, an exit 30b, a reading device 31, a control device 32, a display device 33, a storage section 34, and an actuator 35. At least one of the first member 21 and the second member 22 enters the storage facility 30 through the entrance 30a and exits through the exit 30b. In this embodiment, the entrance 30a and the exit 30b are provided in a common opening. The entrance 30a and the exit 30b may also be provided in different openings.

The reading device 31 is provided above the work space 34a adjacent to the opening of the entrance 30a. When at least one of the first member 21 and the second member 22 enters the storage facility 30, the reading device 31 reads the identification code attached to the member to be stored and obtains identification information for identifying the member to be stored. The reading device 31 may be a known reading device (e.g., a code reader that reads one-dimensional codes and two-dimensional codes). If the identification code is a wireless tag, the storage facility 30 may be equipped with a wireless device capable of wireless communication with the identification code.

The control device 32 includes a known arithmetic device and a storage device, and constitutes a control circuit. The control device 32 is also communicatively connected to the reading device 31, the display device 33, and the actuator 35, and can control these. For example, the control device 32 can control the reading device 31. The control device 32 can also obtain, from the reading device 31, the identification information obtained by the reading device 31.

Furthermore, the control device 32 is connected to the management device 19 shown in FIG. 1 so as to be able to communicate with it. For example, the management device 19 notifies the control device 32 of the occurrence of a changeover in the substrate-related work line 10L. The management device 19 can also notify the control device 32 of the occurrence of a shortage of at least one of the first member 21 and the second member 22 supplied to the substrate-related work line 10L. The management device 19 can also notify the control device 32 of the possibility of a changeover occurring within a specified period. The management device 19 can also notify the control device 32 of the possibility of a shortage of at least one of the first member 21 and the second member 22 within a specified period. The control device 32 causes the necessary members to be shipped out based on these notifications.

The display device 33 may be a known display device, and displays various information so that the worker can see it. The display device 33 displays, for example, component information showing information about the components stored in the storage section 34 in response to the worker's operation. The component information may include, for example, the type, model, and number of components in stock. In addition, the component information of the first component 21 may include the type, model, vendor name, remaining number, humidity control level, expiration date, and the like of the part 91 stored in the first component 21.

In this embodiment, the display device 33 is configured as a touch panel, and the display device 33 also functions as an input device that accepts various operations by the worker. For example, the worker can use the touch panel (the display device 33 that functions as an input device) to specify the desired item to be removed from the storage facility 30. In this case, the control device 32 causes the specified item to be removed.

The storage section 34 may take various forms as long as it can store at least one of the first member 21 and the second member 22. As shown in FIG. 3B, the storage section 34 of this embodiment includes a plurality of storage units 34b, which are arranged in a circle when viewed in the vertical direction (Z-axis direction). As shown in FIG. 3C, the storage unit 34b includes, for example, two types of storage spaces, storage space 34b1 and storage space 34b2.

The storage space 34b1 and the storage space 34b2 can be provided in a plurality of spaces along the vertical direction (Z-axis direction). The size (width, depth, and height) of the storage space 34b1 is set so that the first member 21 can be stored therein. The size (width, depth, and height) of the storage space 34b2 is set so that the second member 22 or the second member 22 equipped with the first member 21 can be stored therein.

The actuator 35 is disposed inside the storage units 34b when viewed in the vertical direction (Z-axis direction), and grasps and moves at least one of the first member 21 and the second member 22. The actuator 35 may take various forms as long as it can grasp and move the above-mentioned members. For example, the actuator 35 may be a robot arm (multi-joint robot).

When at least one of the first member 21 and the second member 22 is stored, the actuator 35 causes the gripping unit to grip the member carried into the working space 34a from the storage entrance 30a. The actuator 35 moves the gripping unit holding the member to a specified storage space and releases the grip of the member by the gripping unit. This allows the member to be stored in the storage space. Also, when at least one of the first member 21 and the second member 22 is removed from the storage space, the actuator 35 causes the gripping unit to grip the member stored in the storage space. The actuator 35 moves the gripping unit holding the member to the working space 34a and releases the grip of the member by the gripping unit. This allows the member to be removed.

1-4. Shelf 40, dry box 50 and oven 60
The shelf 40 can place at least one of the first member 21 and the second member 22. Unlike the storage 30, the shelf 40 is not sealed and stores at least one of the first member 21 and the second member 22 at the ambient temperature and humidity of the room of the production facility. The shelf 40 can be provided with a storage space similar to the storage section 34 of the storage 30. The arrangement of the storage space is not limited and can take various forms.

Furthermore, for example, the components 91 housed in the first member 21 include resin-sealed components. When such components that have been exposed to the atmosphere for longer than a specified time and have absorbed moisture from the atmosphere are heated in the reflow furnace 10d shown in FIG. 1, the moisture contained in the components may vaporize and expand in volume, resulting in damage. Such moisture-sensitive components 91 are called MSL (Moisture Sensitivity Level) components, and the limit time that they can be exposed to the atmosphere (the maximum time that they can be used in production) is specified for each type of component.

The dry box 50 is equipped with a humidity control unit that maintains a constant humidity state inside the box, and can store at least one of the first member 21 and the second member 22 at a constant humidity. The dry box 50 can store the members at a humidity control level specified for MSL parts. Therefore, if the part 91 contained in the first member 21 is an MSL part, storing the first member 21 in the dry box 50 can stop the decrease in the remaining time (floor life) that the part 91 can be used in production.

If an MSL part exceeds the limit of the time it can be exposed to the atmosphere, it can be dried at a specified temperature for a specified time to recover the limit of the time it can be exposed to the atmosphere (the maximum time it can be used in production). The specified temperature, specified time, and number of times it can be dried are specified for each humidity control level of the MSL part.

The oven 60 is equipped with a drying section that dries the interior of the oven to a predetermined humidity level and maintains the humidity level, and can dry at least one of the first member 21 and the second member 22 to the predetermined humidity level and store the member at the predetermined humidity level. The oven 60 can dry and store the member under conditions specified for MSL parts. Therefore, if the part 91 housed in the first member 21 is an MSL part, storing the first member 21 in the oven 60 can restore the limit time that the first member 21 can be exposed to the atmosphere (the maximum time that can be used in production).

1-5. Member management device 80
The material management device 80 manages the location of the first material 21 and the second material 22. As shown in Fig. 1, the production facility includes a warehouse area ZA1, a picking area ZA2, and an off-site setup area ZA3. The warehouse area ZA1 is an area in which at least one of the first material 21 and the second material 22 is stored for a longer period of time than the picking area ZA2, and includes at least one storage 30 (one in the figure).

The picking area ZA2 is an area for temporarily storing the above-mentioned materials, and is equipped with at least one shelf 40 (two in the figure). The above-mentioned materials stored in the storage 30 in the warehouse area ZA1 are transported to at least one of the picking area ZA2 and the off-site setup area ZA3. The off-site setup area ZA3 is equipped with at least one shelf 40 (one in the figure), at least one dry box 50 (one in the figure), and at least one oven 60 (one in the figure). In the off-site setup area ZA3, at least one of the first material 21 and the second material 22 transported from at least one of the warehouse area ZA1 and the picking area ZA2 can be stored in the shelf 40, the dry box 50, or the oven 60.

In addition, in the off-site setup area ZA3, supply preparation work is performed to combine the first member 21 and the second member 22 so that they can be supplied to the substrate-related work line 10L. For example, if the first member 21 is a reel 21a and the second member 22 is a feeder 22a, the worker mounts the reel 21a on the feeder 22a. At this time, the worker reads the identification code 23a attached to the reel 21a using, for example, a code reader of a portable terminal. The worker also reads the identification code 24a attached to the feeder 22a using, for example, a code reader of a portable terminal.

As a result, identification information identifying the reel 21a (first identification information identifying the first member 21) and identification information identifying the feeder 22a (second identification information identifying the second member 22) are transmitted to the member management device 80. When the member management device 80 acquires the above identification information, it generates combination information indicating the combination of the first member 21 and the second member 22. Specifically, the combination information associates the first identification information identifying the first member 21 with the second identification information identifying the second member 22. The member management device 80 stores the combination information in, for example, a storage device 80m shown in FIG. 4. The storage device 80m may be any storage device capable of storing various information, and may be any known storage device.

Furthermore, the component management device 80 updates the component location information when at least one of the first component 21 and the second component 22 is moved. For example, when a worker moves a component, the worker reads the identification code using a code reader on the mobile terminal. If the mobile terminal has a positioning function, the mobile terminal transmits the component location information to the component management device 80 after reading the identification code. The component management device 80 updates the component location information stored in the memory device 80m to the received location information.

In addition, the worker can also use a code reader on a portable terminal or the like to read the location codes provided in the warehouse area ZA1, the picking area ZA2 and the off-site setup area ZA3. As a result, the location information of the area in which the read location code is provided is transmitted to the material management device 80. The worker can also use a code reader on a portable terminal or the like to read the location codes provided in the storage devices 70 (storage house 30, shelf 40, dry box 50, oven 60, etc.). As a result, the location information of the storage devices 70 in which the read location code is provided is transmitted to the material management device 80. In addition, the storage devices 70 can also transmit location information to the material management device 80.

In the off-site setup area ZA3, a release operation is performed as necessary to release the combination of the first member 21 and the second member 22 that are no longer being used in production on the substrate-related work line 10L. For example, if the first member 21 is a reel 21a and the second member 22 is a feeder 22a, the worker removes the reel 21a from the feeder 22a. The removed reel 21a is stored in a specified storage device 70, and the feeder 22a is stored in a specified storage device 70. Furthermore, if there is no need to release the combination, the reel 21a and the feeder 22a are stored in the specified storage device 70 in a combined state.

In this way, the storage device 70 may receive both the first member 21 and the second member 22, or may receive either the first member 21 or the second member 22. When both the first member 21 and the second member 22 are stored in the storage device 70, the combination information indicating the combination of the first member 21 and the second member 22 needs to be maintained. In contrast, when either the first member 21 or the second member 22 is stored, the above combination information needs to be deleted. For example, when the above combination information is deleted by an operator, there is a possibility that the number of work steps will increase and work errors (forgetting to delete, erroneous deletion, etc.) will occur.

Therefore, when the first member 21 or the second member 22 is stored in the storage device 70, the member management device 80 of this embodiment deletes combination information indicating the combination of the first member 21 and the second member 22 that was used before the storage. Specifically, the member management device 80 of this embodiment includes a judgment unit 81 and a deletion unit 82. The member management device 80 can also include a setting unit 83. The member management device 80 can also include an update unit 84. As shown in FIG. 4, the member management device 80 of this embodiment includes a judgment unit 81, a deletion unit 82, a setting unit 83 and an update unit 84.

The judgment unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 can be provided in various control devices. For example, the judgment unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 can be provided in the management device 19. The judgment unit 81 can also be provided in a control device of the storage device 70 (for example, the control device 32 of the storage 30), the control device of the mobile terminal device described above, etc. The judgment unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 can also be formed on the cloud. As shown in FIG. 4, in this embodiment, the judgment unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 are provided in the management device 19.

The member management device 80 also executes control in accordance with the flowchart shown in FIG. 5. The judgment unit 81 performs the judgment shown in step S12. The deletion unit 82 performs the process shown in step S13. The setting unit 83 performs the process shown in step S11. The update unit 84 performs the process shown in step S14.

1-5-1. Judgment section 81
The determination unit 81 determines whether or not a first member 21 that houses a component 91 to be mounted on a board 90 or a second member 22 that is used together with the first member 21 will be stored in the storage device 70. The determination unit 81 only needs to be able to determine whether or not the first member 21 or the second member 22 will be stored in the storage device 70, and may take various forms.

For example, assume that the first member 21 is a reel 21a, the second member 22 is a feeder 22a, and the reel 21a that is not attached to the feeder 22a is stored in the storage device 70. In this case, the worker can read the identification code 23a attached to the reel 21a using, for example, the code reader of the mobile terminal device described above, and then store the reel 21a in the storage device 70.

For example, the storage facility 30 can also use the reading device 31 to read the identification code 23a attached to the stored reel 21a. The shelf 40, dry box 50 or oven 60 can be equipped with a reading device similar to the reading device 31, and can also read the identification code 23a attached to the stored reel 21a, similar to the storage facility 30. In either case, the judgment unit 81 can judge the storage of a reel 21a that is not equipped to the feeder 22a (the storage of the first member 21) by acquiring the identification information that identifies the reel 21a (first identification information that identifies the first member 21).

Next, assume that the first member 21 is a reel 21a, the second member 22 is a feeder 22a, and the feeder 22a equipped with the reel 21a is stored in the storage device 70. In this case, the worker can read the identification code 24a attached to the feeder 22a using, for example, the code reader of the mobile terminal device described above, and then store the feeder 22a equipped with the reel 21a in the storage device 70.

Also, for example, the storage 30 can use the reading device 31 to read the identification code 24a attached to the stored feeder 22a. The shelf 40, dry box 50 or oven 60 can be equipped with a reading device similar to the reading device 31, and can read the identification code 24a attached to the stored feeder 22a, similar to the storage 30. In either case, the determination unit 81 can determine the storage of the feeder 22a equipped with the reel 21a (the storage of both the first member 21 and the second member 22) by acquiring the identification information identifying the feeder 22a (the second identification information identifying the second member 22).

In this way, the determination unit 81 can determine that the first member 21 or the second member 22 will be stored in the storage device 70 when it acquires one of the first identification information identifying the first member 21 and the second identification information identifying the second member 22. In addition, the determination unit 81 can determine that both the first member 21 and the second member 22 will be stored in the storage device 70 when it acquires the other of the first identification information identifying the first member 21 and the second identification information identifying the second member 22.

The member management device 80 may include a reading device 80r that obtains first identification information by reading the first identification member 21r attached to the first member 21, and obtains second identification information by reading the second identification member 22r attached to the second member 22. This allows the judgment unit 81 to obtain the first identification information or the second identification information using the reading device 80r. In the above example, the identification code 23a attached to the reel 21a corresponds to the first identification member 21r, and the identification code 24a attached to the feeder 22a corresponds to the second identification member 22r. In addition, the code reader and reading device 31 of the portable terminal correspond to the reading device 80r.

As described above, the reel 21a or the feeder 22a may be stored by removing the reel 21a from the feeder 22a that is no longer used in the production of the substrate-related work line 10L. Also, the carrier tape 21t of the reel 21a is rewound before the reel 21a is removed from the feeder 22a. Therefore, the determination unit 81 can also determine that the reel 21a or the feeder 22a will be stored in the storage device 70 when the carrier tape 21t of the reel 21a held by the feeder 22a that is no longer used in production is rewound and one of the first identification information and the second identification information is acquired.

Whether or not the feeder 22a is no longer used in production can be known from the management device 19 that manages the production of the substrate-related work line 10L. Also, whether or not the carrier tape 21t has been rewound can be known through communication between the feeder 22a and a work table equipped with the feeder 22a for rewinding the carrier tape 21t. The determination unit 81 can obtain this information from the management device 19 and the work table.

The storage device 70 may take various forms as long as it can store at least one of the first member 21 and the second member 22. The storage device 70 of this embodiment is a storage cabinet 30 capable of storing at least one of the first member 21 and the second member 22, a shelf 40 on which the member can be placed, a dry box 50 in which the member can be stored at a constant humidity, or an oven 60 in which the member can be dried to a predetermined humidity and stored at the predetermined humidity. Therefore, at least one of the first member 21 and the second member 22 can be stored in the storage cabinet 30, the shelf 40, the dry box 50, or the oven 60.

As in the above example, when the determination unit 81 acquires identification information of a member (in the above example, the reel 21a and the first member 21) that is to be stored alone in the storage device 70, the determination unit 81 can determine that the member (the reel 21a and the first member 21) will be stored in the storage device 70. Also, when the determination unit 81 acquires identification information of a member (in the above example, the feeder 22a and the second member 22) that is not to be stored alone, the determination unit 81 can determine that both the first member 21 and the second member 22 (the reel 21a and the feeder 22a) will be stored in the storage device 70. Furthermore, which of the first member 21 and the second member 22 is to be stored alone can be specified arbitrarily. The worker or the reading device 31 reads the identification code according to the specification.

The judgment unit 81 can also judge the entry of the first member 21, the entry of the second member 22, or the entry of both the first member 21 and the second member 22. In this embodiment, when the first member 21 is entered alone, first identification information that identifies the first member 21 is acquired by the worker or the reading device 31. When the judgment unit 81 acquires the first identification information, it can judge that the first member 21 will be entered into the storage device 70.

In the above embodiment, when the second member 22 is stored alone, second identification information that identifies the second member 22 is acquired by the worker or the reading device 31. The judgment unit 81 can determine that the second member 22 will be stored in the storage device 70 when the second identification information is acquired. In addition, when both the first member 21 and the second member 22 are stored in the above embodiment, both the first identification information and the second identification information are acquired by the worker or the reading device 31. The judgment unit 81 can determine that both the first member 21 and the second member 22 will be stored in the storage device 70 when the first identification information and the second identification information are acquired.

1-5-2. Deletion unit 82
When the judgment unit 81 determines that the first member 21 or the second member 22 is to be stored, the deletion unit 82 deletes the combination information indicating the combination of the first member 21 and the second member 22 that was used before the storage (step S13 shown in Figure 5).

As described above, the combination information associates first identification information that identifies the first member 21 with second identification information that identifies the second member 22. In this embodiment, the combination information is stored in the storage device 80m shown in FIG. 4. Therefore, when the judgment unit 81 judges that the first member 21 or the second member 22 is to be stored, the deletion unit 82 deletes the combination information (association between the first identification information and the second identification information) stored in the storage device 80m.

1-5-3. Setting section 83
Depending on the type of the first member 21 or the second member 22, there may be cases where the worker is required to delete the combination information. Therefore, the member management device 80 of this embodiment is provided with a setting unit 83. The setting unit 83 sets in advance whether or not to delete the combination information when the first member 21 or the second member 22 is stored in the storage device 70 (step S11 shown in FIG. 5). The setting by the setting unit 83 can be stored in, for example, the storage device 80m shown in FIG. 4.

Figure 6 shows an example of settings made by the setting unit 83. Setting item number 1 shows a case where a reel 21a that is not mounted on a feeder 22a is stored in the storage unit 30. The setting example in this case is "delete", which indicates that the deletion unit 82 deletes the combination information. Setting item number 2 shows a case where a tray 21b that is not mounted on a tray pallet 22b is stored in the storage unit 30. The setting example in this case is "delete", which indicates that the combination information is deleted.

The setting items numbered 3 and onwards are set in the same way. Also, the second members 22 that are not equipped with a first member 21 can be set in the same way. In this way, the setting unit 83 can set whether or not to delete combination information for each combination of multiple types of first members 21 and multiple types of storage devices 70. Also, the setting unit 83 can set whether or not to delete combination information for each combination of multiple types of second members 22 and multiple types of storage devices 70.

In a configuration in which the member management device 80 includes a setting unit 83, the judgment unit 81 judges whether a predetermined member (first member 21 or second member 22) previously set by the setting unit 83 is to be stored in a predetermined storage device 70 (step S12 shown in FIG. 5). In addition, the deletion unit 82 deletes the combination information for the first member 21 or second member 22 for which the combination information is set to be deleted by the setting unit 83 (step S13).

For example, assume that a reel 21a that is not mounted on a feeder 22a is stored in the storage 30. In this case, the judgment unit 81 judges that a predetermined component (reel 21a) previously set by the setting unit 83 is stored in a predetermined storage device 70 (storage 30) (if Yes in step S12). According to the setting of number 1, when a reel 21a that is not mounted on a feeder 22a is stored in the storage 30, the combination information is set to be deleted. Therefore, the deletion unit 82 deletes the combination information of the first identification information that identifies the reel 21a and the second identification information that identifies the feeder 22a (step S13).

1-5-4. Update section 84
When the first member 21 or the second member 22 is stored in the storage device 70, the update unit 84 updates the location information indicating the location of the stored first member 21 or second member 22 (step S14 shown in FIG. 5). As described above, the location information is stored in, for example, the storage device 80m shown in FIG. 4.

Figure 7 shows an example of location information. The location information shown in the figure includes identification information, entry date and time, exit date and time, area, storage location and storage information. The identification information is information that identifies the entered first member 21 or second member 22. As described above, the identification information that identifies the first member 21 is the first identification information, and the identification information that identifies the second member 22 is the second identification information. The entry date and time is the date and time that the first member 21 or second member 22 entered the storage device 70. The exit date and time is the date and time that the first member 21 or second member 22 was exited from the storage device 70.

The area is the region in which the storage device 70 is located. As described above, in the production facility of this embodiment, the area is the warehouse area ZA1, the picking area ZA2, or the off-site setup area ZA3. The storage location is the location where the first member 21 or the second member 22 stored in the storage device 70 is stored. The storage location can be identified by the location of the storage device 70 or the storage space of the storage device 70 (for example, storage space 34b1 or storage space 34b2 of the storage warehouse 30). The storage information is information that indicates the storage status of the first member 21 or the second member 22 in the storage device 70. Of the ambient temperature and humidity within the storage device 70, at least the humidity is included in the storage information.

For example, this shows that the component (first component 21 or second component 22) indicated by identification information ID1 numbered 1 was received at date and time DT11 and removed at date and time DT21. It also shows that the component was stored in storage location SL1 in area AR11 in the state indicated by storage information IF1. What has been said above about component numbered 1 also applies to components numbered 2 and onwards.

Thus, in this embodiment, the location information includes at least the storage location and identification information among the entry date and time, area, storage location, and identification information. Therefore, when the first member 21 or the second member 22 is entered into the storage device 70, the update unit 84 can update at least the storage location among the entry date and time, area, and storage location of the entered first member 21 or second member 22.

2. Others In the embodiment, the first member 21 is mainly a reel 21a, and the second member 22 is a feeder 22a. However, the first member 21 and the second member 22 are not limited to these. For example, the first member 21 may be a tray 21b, and the second member 22 may be a tray pallet 22b. The first member 21 may be a wafer component, and the second member 22 may be a holding member that holds the wafer component. The first member 21 may be a stick component, and the second member 22 may be a holding member that holds the stick component. The first member 21 may be a part (a scrap) of the carrier tape 21t, and the second member 22 may be a container that contains a part (a scrap) of the carrier tape 21t.

3. Component management method What has already been described about the component management device 80 also applies to the component management method. Specifically, the component management method comprises a judgment process and a deletion process. The control performed by the judgment unit 81 corresponds to the judgment process. The control performed by the deletion unit 82 corresponds to the deletion process. The component management method can also comprise a setting process. The control performed by the setting unit 83 corresponds to the setting process. The component management method can also comprise an update process. The control performed by the update unit 84 corresponds to the update process.

4. Example of Effects of the Embodiment The member management device 80 includes a determination unit 81 and a deletion unit 82. As a result, when the first member 21 or the second member 22 is stored in the storage device 70, the member management device 80 can delete combination information indicating the combination of the first member 21 and the second member 22 that was used before the first member 21 or the second member 22 is stored in the storage device 70. What has been described above about the member management device 80 also applies to the member management method.
