Description

[Technical field]

[0001] The present invention relates to a parts storehouse. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known a component storage cabinet that includes a plurality of storage sections for storing component housing members that house components to be mounted on a board. Such a component storage cabinet is disclosed in, for example, JP 2012-182246 A.

[0003] The above-mentioned Japanese Patent Application Laid-Open No. 2012-182246 discloses a reel warehouse equipped with a reel shelf on which a plurality of reels in which components are enclosed at a predetermined pitch are arranged. In the reel warehouse, when the remaining number of components in a component mounting device falls below a preset number, a necessary reel is identified from among the reels on the reel shelf, and the identified reel is then stored in a transport case. Then, in the reel warehouse, an instruction to transport the transport case to the component mounting device is transmitted to an operator. In this manner, the reel is removed from the reel warehouse. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2012-182246 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the reel warehouse of JP 2012-182246 A, if a reel is not identified as a necessary reel, the reel remains in the reel warehouse. In this case, if the remaining reel remains in the reel warehouse and the expiration date passes, the components in the reel cannot be used as components to be mounted on a board, and the remaining reel is considered not to be shipped out from the reel warehouse. In this case, in the reel warehouse of JP 2012-182246 A, the number of reel shelves on which usable reels are placed is reduced due to unusable reels being placed on the reel shelves. It is therefore desirable to suppress the reduction in the number of reel shelves (storage units) on which usable reels are placed.

[0006] The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to provide a parts storage facility that can suppress a reduction in the number of storage sections in which usable parts are placed. [Means for solving the problem]

[0007] A component storage facility according to a first aspect of the present invention comprises a plurality of storage sections for storing component storage members containing components to be mounted on a board, a component removal mobile robot for removing the component storage members stored in each of the plurality of storage sections and transporting them to an outgoing position, and an unused component storage section in which unused component storage members which contain unused parts among the component storage members stored in each of the plurality of storage sections and which have not been selected as parts to be outgoing from the outgoing position are transported by the component removal mobile robot and in which a plurality of unused component storage members are stored in a stacked state.

[0008] As described above, the component storage according to the first aspect of the present invention includes an unused component storage section in which a plurality of unused component storage members are stored in a stacked state. By evacuating the unused component storage members to the unused component storage section, a space for storing the component storage members can be secured for the number of unused component storage members stacked on top of each other, compared to a case in which the unused component storage members remain in each of the plurality of storage sections. As a result, a reduction in the number of storage sections in which usable components are arranged can be suppressed.

[0009] In the component storage according to the first aspect, the unused component storage section preferably has a volume larger than the volume of each of the storage sections. With this configuration, a sufficient number of unused component storage members can be stacked and stored in the unused component storage section, making it easy to ensure a sufficient number of storage sections capable of storing usable component storage members.

[0010] The parts storage according to the first aspect preferably further comprises an information management unit that manages unused parts information associated with the unused parts, and is configured to transport the unused parts storage members to the unused parts storage members by the parts pick-up mobile robot based on the unused parts information of the information management unit. With this configuration, the unused parts storage members to be transported by the parts pick-up mobile robot can be easily selected based on the unused parts information managed by the information management unit, and therefore the unused parts storage members can be easily transported by the parts pick-up mobile robot.

[0011] In this case, the information management unit is preferably configured to manage non-use conditions for determining whether the component housing members stored in each of the plurality of storage units are unused component housing members, and is configured to transport the unused component housing members to the unused component housing units by the component pick-up mobile robot based on unused component information associated with unused components based on the non-use conditions. With this configuration, the information management unit can select unused component housing members based on the non-use conditions, and the component pick-up mobile robot can transport unused component housing members that meet the non-use conditions to the unused component housing units. As a result, the selection of unused component housing members can also be performed automatically, which further reduces the workload of the worker.

[0012] In a component storage facility equipped with an information management unit for managing the non-use conditions, the non-use conditions preferably include at least one of a first deadline set based on the time elapsed since the date of opening the component housing member, a second deadline set based on the time elapsed since the date of registration of information on the component housing member in the information management unit, and an undecided use condition set when the component housing member is undecided for use in the production of boards for a predetermined period of time or more. With this configuration, the component housing members can be prevented from remaining in the multiple storage units for an unnecessarily long period of time, thereby suppressing a decrease in the operating rate of the storage units. As a result, the multiple storage units can be used effectively.

[0013] In the component storage having the above-mentioned first deadline, second deadline, and undecided condition, the information management unit is preferably configured to be able to add conditions different from the first deadline, second deadline, and undecided condition. With this configuration, the information management unit can manage the non-use conditions according to the actual situation such as the production plan for producing the board, and therefore the information management unit can select a more appropriate unused component housing member.

[0014] In the parts storehouse equipped with the information management unit for managing the non-use conditions, preferably, a display unit for displaying the non-use conditions in a selectable manner is further provided. With this configuration, when the non-use conditions are set by an operator, the operator can select the non-use conditions while visually checking the non-use conditions displayed on the display unit, so that the operator can easily select the non-use conditions intended by the operator.

[0015] In the parts storage facility equipped with the information management unit, the information management unit is preferably configured to acquire the storage status of the unused part storage members in the unused part storage section based on the number of times the unused part storage members have been carried to the unused part storage section by the part removal mobile robot. With this configuration, it is possible to determine whether the unused part storage section is full or not based on the storage status acquired by the information management unit, so that the part removal robot can be prevented from carrying unused storage members to an unused part storage section that is full.

[0016] The component storage according to the first aspect preferably further comprises a storage body having the plurality of storage sections, the unused component storage section, and the component removal mobile robot disposed therein, the storage body including a confirmation window for visually checking the unused component storage section from outside the storage body. With this configuration, an operator can check the storage state of the unused component storage members in the unused component storage section through the confirmation window, and the operator can easily determine whether or not the unused component storage members need to be collected.

[0017] The parts storage according to the first aspect preferably further comprises a storage structure having both the plurality of storage sections and the unused parts storage section. With this configuration, the plurality of storage sections and the unused parts storage section can be integrated into a single structure, thereby simplifying the structure of the parts storage.

[0018] In the component storage facility that acquires the storage status of the unused component storage member based on the number of times the unused component storage member is carried to the unused component storage section, the component storage facility preferably further includes a light detection unit that detects whether the unused component storage member is at a predetermined height position in the unused component storage section by light. With this configuration, the worker can confirm the storage status of the unused component storage member not only based on the number of times the unused component storage member is carried to the unused component storage section by the component picking mobile robot, but also based on the height position of the unused component storage member in the unused component storage section detected by the light detection unit. As a result, the worker can accurately know the storage status of the unused component storage member in the unused component storage section.

[0019] In the part storage facility that acquires the storage status of the unused part storage members based on the number of times the unused part storage members are transported to the unused part storage section, the part storage facility preferably further comprises a weight measuring device that measures the total weight of the unused part storage members transported to the unused part storage section. With this configuration, the worker can check the storage status of the unused part storage members not only by the number of times the unused part storage members are transported to the unused part storage section by the part picking mobile robot, but also by the total weight of the unused part storage members measured by the weight measuring device. As a result, the worker can accurately know the storage status of the unused part storage members in the unused part storage section.

[0020] In the parts storage including the photodetector or weight measuring device, preferably, a light detection unit that detects whether the unused part storage member is at a predetermined height position in the unused part storage unit by light; When the light detector detects that the unused part housing member is at a predetermined height, A notification unit that notifies the operator, or a weight measuring device for measuring a total weight of the unused part storage members transferred to the unused part storage section; A notification section that notifies the worker when the measurement result of the weight measuring device exceeds a threshold value. and, With this configuration, the worker can be sure to know the storage state of the unused part storage section, so that the worker can reliably collect the unused part storage members from the unused part storage section.

[0021] In the part storage facility having the non-use condition, preferably, a plurality of unused part storage sections are provided, and the part removal mobile robot is configured to, based on the unused part information based on the non-use condition acquired from the information management section, separate the unused part storage members and transport them to the plurality of unused part storage sections according to the non-use condition. With this configuration, when an operator retrieves the unused part storage members from the unused part storage sections, the operator can save the trouble of separating the unused part storage members collected in the unused part storage sections, thereby suppressing an increase in the operator's workload.

[0022] In the parts storage including the information management unit, preferably, a robot control unit is provided separately from the information management unit and configured to control the part pick-up mobile robot to transport the unused part storage member to the unused part storage section based on the unused part position information included in the unused part information, the unused part storage section position information, and the part pick-up mobile robot position information. With this configuration, the control of the part pick-up mobile robot can be shared by the robot control unit, thereby reducing the processing load of the information management unit.

[0023] A parts storage facility according to a second aspect of the present invention includes a plurality of storage sections for storing storage members containing items used for mounting boards or board mounting work, a removal mobile robot for removing the storage members stored in each of the plurality of storage sections and transporting them to an outgoing position, and an unused item storage section in which unused item storage members for containing unused items among the storage members stored in each of the plurality of storage sections that have not been selected as items to be outgoing from the outgoing position are transported by the removal mobile robot and in which multiple unused item storage members are stored in a stacked state.

[0024] As described above, the parts storage facility according to the second aspect of the present invention includes an unused item storage section in which a plurality of unused item storage members are stored in a stacked state. This allows the unused item storage members to be evacuated to the unused item storage section, and thus ensures that the number of storage sections capable of storing the storage members is equal to the number of stacked storage sections, compared to a case in which unused item storage members remain in each of the plurality of storage sections. As a result, it is possible to prevent a decrease in the number of storage sections in which usable parts are arranged. Effect of the Invention

[0025] According to the present invention, as described above, it is possible to suppress a decrease in the number of storage units in which usable parts are placed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0028] [First embodiment] The configuration of a parts storage facility 2 according to a first embodiment of the present invention will be described with reference to FIGS.

[0029] As shown in FIG. 1, the component mounting system 100 includes a component mounting line 1 and a component storage facility 2.

[0030] (Component mounting line configuration) A plurality of component mounting lines 1 are provided. Each component mounting line 1 includes a loader 11, a printer 12, a print inspection machine 13, a dispenser device 14, a plurality (three) of component mounting devices 15, an appearance inspection device 16, a reflow device 17, an appearance inspection device 18, and an unloader 19. The component mounting line 1 is configured such that the board is transported from the upstream side (left side) to the downstream side (right side) along the manufacturing line. Although three component mounting devices 15 are provided, one or two, or four or more may be provided.

[0031] The loader 11 has the role of holding the board (wiring board) S before components E are mounted, and of carrying the board into the component mounting line 10. The components E include small piece-like electronic components such as LSIs, ICs, transistors, capacitors, and resistors. The components E are an example of an "article" in the claims.

[0032] The printer 12 is a screen printer and has a function of applying cream solder onto the mounting surface of the board. The print inspection machine 13 has a function of inspecting the condition of the cream solder printed by the printer 12. The dispenser device 14 has a function of applying cream solder, adhesive, etc. onto the board.

[0033] The component mounting device 15 has a function of mounting (mounting) components E at predetermined mounting positions on a board on which cream solder has been printed. The components E to be mounted by the component mounting device 15 are replenished by replacing the reel 3 attached to the component mounting device 15 with a reel 3 stored in the component storage 2. Here, the reel 3 stores a plurality of components E. The reel 3 is an example of a "component storage member" and a "storage member" in the claims.

[0034] The component mounting device 15 and the component storage 2 are connected to be able to communicate with each other. As a result, the component storage 2 selects the necessary reel 3 based on a request for the necessary reel 3 from the component mounting device 15, and then takes out the selected reel 3.

[0035] The appearance inspection device 16 is provided downstream of the multiple component mounting devices 15. The appearance inspection device 16 has a function of inspecting the appearance of the board on which the components E are mounted by the component mounting device 15. The reflow device 17 has a function of melting the solder by performing a heat treatment to bond the components E to the electrode portions of the board. The reflow device 17 is configured to perform a heat treatment while transporting the board on the lane. The appearance inspection device 18 is provided downstream of the reflow device 17. The appearance inspection device 18 has a function of inspecting the appearance of the board after the heat treatment is performed by the reflow device 17. The unloader 19 has a role of discharging the board from the component mounting line 1 after the components E are mounted thereon.

[0036] (Parts storage configuration) 2 and 3, the component storage 2 is configured to store components E in a state in which the temperature, humidity, and the like within the storage are appropriately adjusted. The components E stored in the component storage 2 are components that are frequently used by the component mounting device 15. As described above, the component storage 2 automatically selects the necessary reel 3 based on a request for the necessary reel 3 from the component mounting device 15, and then removes the selected reel 3, thereby reducing the burden on the worker in removing the reel 3 from the storage.

[0037] Here, the part E is stored in the reel 3. The part E may also be stored in the part storage warehouse 2 in a state where it is stored (placed) on a tray covered with a lid. The part storage warehouse 2 is also configured to be able to store jigs (backup pins, etc.). In this case, the jigs are stored in a storage box in the part storage warehouse 2. The tray and storage box are examples of a "part storage member" and a "storage member" in the claims. The jig is an example of an "article" in the claims.

[0038] In the following description, as an example, the parts storage 2 in which the reel 3 is stored will be described.

[0039] The parts storage facility 2 includes a storage main body 21, an exit door 22, a display unit 23, an operation unit 24, a parts removal mobile robot 25, a robot control unit 26, a storage structure 27, and an information management unit 28.

[0040] Here, the up-down direction is the Z direction, the up direction is the Z1 direction, and the down direction is the Z2 direction. The horizontal direction toward the display unit 23 is the Y1 direction, and the horizontal direction opposite the display unit 23 is the Y2 direction. The direction perpendicular to the Z direction and the Y direction is the X direction, and one side of the X direction is the X1 direction, and the other side of the X direction is the X2 direction.

[0041] The storage unit main body 21 is a housing in which the storage structure 27 and the part-picking mobile robot 25 are disposed. Here, the side surface of the storage unit main body 21 facing the Y1 direction is referred to as one side surface 21a. On one side surface 21a, an output door 22, a display unit 23, an operation unit 24, and an information management unit 28 are disposed. The output door 22 is a door provided at an output position 22a through which the part E stored in the part storage 2 is output. The storage unit main body 21 also includes an inspection window 21b for visually checking an unused part storage unit 27b (described later) from outside the storage unit main body 21. The inspection window 21b is formed by fitting a transparent member into an opening of the storage unit main body 21.

[0042] The display unit 23 is a liquid crystal display having an information management unit 28 built therein. The operation unit 24 is a set of tools such as a keyboard and a mouse that allow an operator to operate the information management unit 28.

[0043] As shown in FIGS. 3 and 4, the part-picking mobile robot 25 is configured to pick up the reels 3 stored in each of a plurality of storage units 27a (to be described later) and carry them to the delivery position 22a.

[0044] Specifically, the part-picking moving robot 25 has an X-axis moving mechanism 25a, a Y-axis moving mechanism 25b, a Z-axis moving mechanism 25c, a support portion 25d, and a pair of handlers 25e.

[0045] The X-axis moving mechanism 25a is configured to move the support portion 25d in the X direction. The X-axis moving mechanism 25a has a motor (not shown) and a ball screw (not shown). The Y-axis moving mechanism 25b is configured to move the support portion 25d in the Y direction. The Y-axis moving mechanism 25b has a motor (not shown) and a ball screw (not shown). The Z-axis moving mechanism 25c is configured to move the support portion 25d in the Z direction. The Z-axis moving mechanism 25c has a motor (not shown) and a ball screw (not shown).

[0046] The support section 25d supports a pair of handlers 25e. A moving mechanism for moving the pair of handlers 25e in a direction approaching or separating is disposed inside the support section 25d. The pair of handlers 25e are configured to grip the reel 3 by moving in a direction approaching. The pair of handlers 25e are configured to release the grip of the reel 3 by moving in a direction separating.

[0047] The robot control unit 26 is a control panel for controlling the part-taking mobile robot 25. The robot control unit 26 has a CPU (Central Processing Unit) and a storage unit such as a memory. The robot control unit 26 is configured to control the part-taking mobile robot 25 based on the position information of the part-taking mobile robot 25 acquired from the information management unit 28 and the position information of the reels 3 and the like accommodated in the accommodation structure 27. The robot control unit 26 is provided separately from the information management unit 28.

[0048] The storage structure 27 is configured to store reels 3, trays, and the like. Specifically, the storage structure 27 has a plurality of storage sections 27a and an unused part storage section 27b. In this manner, the storage structure 27 is provided with both the plurality of storage sections 27a and the unused part storage section 27b. The unused part storage section 27b is an example of the "unused item storage section" in the claims.

[0049] The storage units 27a are configured to store reels 3 housing components E to be mounted on a board. The storage units 27a are storage shelves for storing the reels 3. The storage units 27a store the reels 3 in a placed state. As shown in FIG. 5, each of the storage units 27a has a space S into which one of the pair of handlers 25e can be inserted. In each of the storage units 27a, the space S is a space on the Z1 direction side of the reel 3 in a placed state.

[0050] <Unused parts storage area> As shown in Fig. 6, the unused part storage section 27b of the first embodiment stores a plurality of stacked unused reels 4 that store unused parts N that have not been selected as parts E to be delivered from the delivery position 22a among the reels 3 stored in each of the multiple storage sections 27a. The unused reels 4 are transported by the part removal mobile robot 25. As a result, the unused reels 4 stored in the unused part storage section 27b are unable to be delivered from the delivery position 22a, which will be described later. The unused reels 4 are an example of the "unused part storage member" and "unused item storage member" in the claims.

[0051] The volume V1 of the unused part storage section 27b is larger than the volume V2 of each of the storage sections 27a. In the Z direction, the length L1 of the unused part storage section 27b is larger than the length L2 of each of the storage sections 27a. The unused part storage section 27b is disposed near the confirmation window 21b. An insertion port 127 is provided on the Z1 direction side of the unused part storage section 27b. The unused reel 4 held by the pair of handlers 25e of the part removal mobile robot 25 is inserted from the insertion port 127. The unused reel 4 inserted from the insertion port 127 is removed by a worker who has entered the part storage 2.

[0052] 7 and 8, an unused part N refers to a part that is not selected as a part E to be delivered from the delivery location 22a. In other words, an unused part N is a part that satisfies a non-use condition C. The non-use condition C refers to conditions such as a first deadline, a second deadline, and an undecided use condition.

[0053] The first deadline is a deadline that is set based on the time that has elapsed since the opening date D2 of the reel 3. Specifically, the first deadline has a moisture deadline C1 and an oxidation deadline C2.

[0054] The moisture expiration date C1 is set for each part identification number Pi (shown as part ID (Identification) in Figs. 7 and 8) as a period (e.g., 30 days) from the opening date D2. The moisture expiration date C1 is the time during which the part E is exposed to a non-dry environment. Therefore, the moisture expiration date C1 does not progress while the reel 3 is stored in the part storage 2. Note that if the part E is stored in a tray, it is possible to restore the moisture expiration date C1 by baking (dehumidifying) the part E.

[0055] The oxidation deadline C2 is set for each part identification number as a deadline (for example, 45 days) from the opening date D2. The oxidation deadline C2 is the expiration date of the part E after opening. Therefore, the oxidation deadline C2 progresses even if the reel 3 is stored in the part storage 2.

[0056] The second term is set based on the amount of time that has passed since the registration date D1 when the information about the reel 3 was registered in the information management unit 28. The second term has a warranty period C3. The warranty period C3 is set based on the amount of time that has passed since the registration date D1 (for example, 365 days) for each part identification number Pi.

[0057] The undecided use condition is set when the use in the production of boards has not been decided for a predetermined period or longer. The undecided use condition has a first undecided condition and a second undecided condition. The first undecided condition is a condition for selecting a part E when the production type of the boards to be produced has changed or the part E has not been used for a long time (a predetermined period or longer) since its last use. The second undecided condition is a condition for selecting a part E that is not scheduled for production for a predetermined period or longer in the monthly board production plan.

[0058] <Robot control unit and information management unit> 7, the information management unit 28 is configured to manage unused part information Na associated with unused part N, and to manage part information Ea associated with part E. The information management unit 28 is configured to manage the unused part information Na and part information Ea as a table.

[0059] Each of the unused part information Na and part information Ea includes information such as a storage address Ad, a part identification number (shown as part ID in FIG. 7) Pi, a part name Pn, a reel identification number (shown as reel ID in FIG. 7) Ri, an attribute At, a registration date D1, an opening date D2, a warehouse date D3, a moisture expiration date C1, an oxidation expiration date C2, a warranty expiration date C3, and a related product type Pc.

[0060] The storage address Ad indicates location information within the component storage warehouse 2 corresponding to each of the multiple storage sections 27a. One reel 3 or unused reel 4 is associated with each of the multiple storage sections 27a. The storage address Ad indicates location information within the component storage warehouse 2 corresponding to the unused component storage section 27b. One or two or more (multiple) unused reels 4 are associated with the unused component storage section 27b. In FIG. 7, three unused reels 4 are associated with the storage address Ad of the unused component storage section 27b.

[0061] The part identification number Pi is a number for identifying the type of unused part N or part E. The part name Pn is an arbitrarily set name for the unused part N or part E. The reel identification number Ri is a number for identifying the unused reel 4 or reel 3. The attribute At indicates the electrical characteristics (e.g., resistance to static electricity) of the unused part N or part E. The registration date D1 is the date and time when the information of the unused reel 4 or reel 3 is registered in the information management unit 28. The opening date D2 is the date and time when the unused reel 4 or reel 3 is opened. The storage date D3 is the date and time when the unused reel 4 or reel 3 is stored in the part storage warehouse 2.

[0062] The moisture expiration date C1, the oxidation expiration date C2, and the warranty expiration date C3 have been explained above, so their explanation will be omitted. The related product type Pc indicates the type of part related to the unused part N contained in the unused reel 4 or the part E contained in the reel 3.

[0063] The information management unit 28 is configured to manage the position information of the part-picking mobile robot 25 as well as the position information of the plurality of storage units 27a and the position information of the unused part storage unit 27b.

[0064] Thus, the robot control unit 26 is configured to control the component removal mobile robot 25 to transport the unused reel 4 to the unused component storage unit 27b based on the unused component information Na. That is, the robot control unit 26 is configured to control the component removal mobile robot 25 to transport the unused reel 4 to the unused component storage unit 27b based on the position information of the unused reel 4 included in the unused component information Na, the position information of the unused component storage unit 27b acquired from the information management unit 28, and the position information of the component removal mobile robot 25.

[0065] The robot control unit 26 is configured to control the part removal mobile robot 25 to transport the reel 3 from the storage position (not shown) to one of the multiple storage units 27a based on the part information Ea. That is, the robot control unit 26 is configured to control the part removal mobile robot 25 to transport the reel 3 to the selected storage unit 27a based on the position information of the storage position acquired from the information management unit 28, the position information of the selected storage unit 27a, and the position information of the part removal mobile robot 25. When the part removal mobile robot 25 transports the reel 3 from the storage position to the selected storage unit 27a, the information of the barcode or QR (Quick Response) code (registered trademark) attached to the reel 3 is automatically read. As a result, the information management unit 28 is configured to acquire the information registered in the barcode or QR code.

[0066] As shown in Fig. 8, information management unit 28 is configured to manage non-use conditions C for determining whether or not a reel 3 stored in each of the plurality of storage units 27a is an unused reel 4. Non-use conditions C are displayed in a selectable state on display unit 23. Information management unit 28 can periodically, manually or automatically, determine whether or not a reel 3 stored in each of the plurality of storage units 27a is an unused reel 4.

[0067] A case where the determination as to whether or not a reel 4 is unused is performed manually will be described below.

[0068] The information management unit 28 is configured to perform a sorting process of the unused part information Na and the part information Ea based on the operation of the worker. In Fig. 8, parts with smaller part identification numbers Pi are sorted to higher numbers, and parts with larger part identification numbers Pi are sorted to lower numbers. The sorting process may be performed by the information management unit 28 based on at least one of the items other than the "part identification number Pi", namely, "storage address Ad", "part name Pn", "reel identification number Ri", "attribute At", "registration date D1", "opening date D2", "warehousing date D3", "moisture expiration date C1", "oxidation expiration date C2", "warranty expiration date C3", and "related product type P".

[0069] The information management unit 28 is configured to perform a filtering process to remove unnecessary unused part information Na and part information Ea from the unused part information Na and part information Ea based on an operation by a worker. In Fig. 8, unused part information Na and part information Ea having a part identification number Pi other than "P1" are removed. The filtering process may be performed by the information management unit 28 based on at least any of the items of "storage address Ad", "part name Pn", "reel identification number Ri", "attribute At", "registration date D1", "opening date D2", "warehousing date D3", "moisture expiration date C1", "oxidation expiration date C2", "warranty expiration date C3" and "related product type P" other than the "part identification number Pi".

[0070] The information management unit 28 is configured to acquire, based on the operation of the worker, from the remaining unused part information Na and part information Ea, the unused part information Na to be transported by the part-picking mobile robot 25. In Fig. 8, since the oxidation period C2 is "expired", the unused reel 4 with the reel identification number Ri of "0001" has been selected by the worker.

[0071] The information management unit 28 is configured to transmit the acquired unused part information Na and the position information of the part-taking mobile robot 25 to the robot control unit 26 based on the operation of the worker. That is, the information management unit 28 is configured to transmit the selected unused part information Na and the position information of the part-taking mobile robot 25 to the robot control unit 26 by the worker pressing the "Archive (Collect)" button shown in Fig. 8. As a result, the robot control unit 26 is configured to transport the unused reel 4 to the unused part storage unit 27b by the part-taking mobile robot 25 based on the unused part information Na associated with the unused part N that satisfies the unused condition C.

[0072] Next, as shown in FIG. 8 and FIG. 9, a case where a determination as to whether or not a reel 4 is unused is automatically and periodically performed will be described.

[0073] The information management unit 28 is configured to acquire the operator's selection result of whether to enable or disable the process of periodically determining whether or not the reel 4 is unused, based on the operator's operation. That is, if the operator wants to enable the process of periodically determining whether or not the reel 4 is unused, the operator performs an operation of checking the "enable / disable" checkbox. Also, if the operator wants to disable the process of periodically determining whether or not the reel 4 is unused, the operator performs an operation of unchecking the "enable / disable" checkbox.

[0074] The information management unit 28 is configured to acquire, based on the operation of the operator, an execution condition for automatically determining whether or not the reel 4 is unused. Here, an example of the operation for setting the execution condition will be described below.

[0075] As shown in FIG. 8, for example, the worker selects a desired non-use condition C from among the non-use conditions C associated with the "combo box" next to "Execution condition 1." The worker selects a desired filtering condition F from among the filtering conditions F associated with the "combo box" next to the "combo box" associated with the non-use condition C. The worker sets the details of the periodic execution condition by operating the "Set" button in the "Periodic execution condition" column.

[0076] As shown in FIG. 9, the operator sets the start time and end time for determining whether or not the reel 4 is unused on the periodic execution condition setting screen. The operator sets the pattern (daily, weekly, monthly or yearly) for determining whether or not the reel 4 is unused on the periodic execution condition setting screen. The operator sets the period (start date, end date, number of repetitions or undetermined end date) for determining whether or not the reel 4 is unused on the periodic execution condition setting screen. The periodic execution condition is set by the operator operating the "OK" button. The periodic execution condition can be canceled by operating the "Cancel periodic settings" button.

[0077] Then, as shown in Fig. 8, the operator operates the "Add" button to add a desired execution condition, and the operator operates the "Delete" button to delete a selected execution condition from among the execution conditions added in the past.

[0078] In the above explanation, the operation of only "Execution condition 1" was described, but the execution condition of "Execution condition 2" can also be set by the same operation. In this case, it is possible to set an execution condition that satisfies "Execution condition 1" and "Execution condition 2". It is also possible to set an execution condition that satisfies "Execution condition 1" or "Execution condition 2".

[0079] In this manner, the information management unit 28 is configured to select (screen) unused reels 4 from among the reels 3 stored in the multiple storage units 27a.

[0080] The information management unit 28 is also configured to be able to add conditions other than the moisture expiration date C1, the oxidation expiration date C2, and the warranty expiration date C3. For example, the information management unit 28 is configured to be able to add conditions such as the above-mentioned undecided use condition based on the operation of the worker. The information management unit 28 is also configured to manage, as the non-use condition C, "storage address Ad," "part identification number Pi," "part name Pn," "reel identification number Ri," "attributes At," "registration date D1," "opening date D2," "warehouse date D3," and "related product type P" in addition to "moisture expiration date C1," "oxidation expiration date C2," and "warranty expiration date C3."

[0081] The information management unit 28 is also configured to acquire the storage state of the unused reels 4 in the unused part storage unit 27b based on the number of times the unused reels 4 have been carried to the unused part storage unit 27b by the part removal mobile robot 25. The information management unit 28 is configured to display the acquired storage state of the unused reels 4 on the display unit 23.

[0082] Thereby, the unused reel 4 stored in the unused part storage section 27b is appropriately taken out from the unused part storage section 27b by the worker who has confirmed the storage state. When the worker takes out the unused reel 4 from the unused part storage section 27b, the worker performs an operation to delete the unused part information Na registered in the information management section 28. Then, the taken out unused reel 4 is stored again in the part storage 2, stored in a storage shelf (not shown) arranged outside the part storage 2, or discarded, at the discretion of the worker. Here, when the unused reel 4 is to be stored again, the worker performs an operation to re-register the unused reel 4 to be stored again as a reel 3 in the information management section 28. The operation to delete the registered unused part information Na may be performed automatically.

[0083] (Effects of the first embodiment) In the first embodiment, the following effects can be obtained.

[0084] In the first embodiment, as described above, the component storage 2 includes an unused component storage section 27b in which a plurality of unused reels 4 are stored in a stacked state. As a result, by evacuating the unused reels 4 to the unused component storage section 27b, it is possible to ensure the number of storage sections 27a capable of storing reels 3 corresponding to the number of stacked unused reels 4, compared to a case in which an unused reel 4 remains in each of the plurality of storage sections 27a. As a result, it is possible to prevent a decrease in the number of storage sections 27a in which usable components are arranged.

[0085] In the first embodiment, as described above, the volume V1 of the unused part storage section 27b is larger than the volume V2 of each of the storage sections 27a. This allows a sufficient number of unused reels 4 to be stacked and stored in the unused part storage section 27b, making it easier to ensure the number of storage sections 27a capable of storing usable reels 3.

[0086] Furthermore, in the first embodiment, as described above, the parts storage 2 includes an information management unit 28 that manages unused part information Na associated with unused parts N. The robot control unit 26 is configured to transport the unused reel 4 to the unused part storage unit 27b by the parts removal mobile robot 25 based on the unused part information Na of the information management unit 28. This makes it easy to select the unused reel 4 to be transported by the parts removal mobile robot 25 based on the unused part information Na managed by the information management unit 28, and therefore makes it easy to transport the unused reel 4 by the parts removal mobile robot 25.

[0087] In the first embodiment, as described above, the information management unit 28 is configured to manage the non-use condition C for determining whether the reel 3 stored in each of the multiple storage units 27a is an unused reel 4. The robot control unit 26 is configured to transport the unused reel 4 to the unused part storage unit 27b by the part removal mobile robot 25 based on the unused part information Na associated with the unused part N based on the non-use condition C. This allows the information management unit 28 to select the unused reel 4 based on the non-use condition C, and allows the part removal mobile robot 25 to transport the unused reel 4 that meets the non-use condition C to the unused part storage unit 27b. As a result, the selection of the unused reel 4 can also be performed automatically, so that an increase in the workload of the worker can be further suppressed.

[0088] In the first embodiment, as described above, the non-use condition C includes a moisture expiration date C1 and an oxidation expiration date C2 (first expiration date) that are set based on the time that has elapsed since the unsealing date D2 when the reel 3 was unsealed. The non-use condition C also includes a warranty expiration date C3 (second expiration date) that is set based on the time that has elapsed since the registration date D1 when the information about the reel 3 was registered in the information management unit 28. The non-use condition C includes an undecided use condition that is set when the use in the production of substrates for a predetermined period of time or more is undecided. This makes it possible to prevent the reels 3 from remaining in the multiple storage units 27a for an unnecessarily long period of time, thereby suppressing a decrease in the operating rate of the storage units 27a. As a result, the multiple storage units 27a can be effectively utilized.

[0089] In the first embodiment, as described above, the information management unit 28 is configured to be able to add conditions other than the moisture expiration date C1, the oxidation expiration date C2, the warranty expiration date C3, and the undecided condition. This allows the information management unit 28 to manage the non-use condition C that is in accordance with the actual situation, such as a production plan for producing boards, and therefore allows the information management unit 28 to select a more appropriate unused reel 4.

[0090] Furthermore, in the first embodiment, as described above, the parts storage 2 includes the display unit 23 that selectably displays the non-use condition C. With this, when the worker sets the non-use condition C, the worker can select the non-use condition C while visually checking the non-use condition C displayed on the display unit 23, so that the worker can easily select the non-use condition C that he or she intends.

[0091] Furthermore, in the first embodiment, as described above, the information management unit 28 is configured to acquire the storage state of the unused reel 4 in the unused part storage unit 27b based on the number of times the unused reel 4 has been carried to the unused part storage unit 27b by the part removal mobile robot 25. This allows the information management unit 28 to determine whether the unused part storage unit 27b is full or not based on the storage state acquired, so that the part removal mobile robot 25 can be prevented from carrying the unused reel 4 to the unused part storage unit 27b that is full.

[0092] In the first embodiment, as described above, the component storage 2 includes a storage body 21 in which a plurality of storage sections 27a, an unused component storage section 27b, and a component removal mobile robot 25 are disposed. The storage body 21 includes a confirmation window 21b for visually checking the unused component storage section 27b from outside the storage body 21. This allows an operator to check the storage state of the unused reels 4 in the unused component storage section 27b through the confirmation window 21b, and therefore the operator can easily determine whether or not it is necessary to collect the unused reels 4.

[0093] In the first embodiment, as described above, the parts storage 2 includes a storage structure 27 that includes both the storage units 27a and the unused parts storage unit 27b. This allows the storage units 27a and the unused parts storage unit 27b to be integrated into a single structure, simplifying the structure of the parts storage 2.

[0094] In the first embodiment, as described above, the parts storage 2 includes a robot control unit 26 that is provided separately from the information management unit 28. The robot control unit 26 is configured to control the part removal mobile robot 25 to transport the unused reel 4 to the unused part storage unit 27b based on the position information of the unused part N included in the unused part information Na, the position information of the unused part storage unit 27b, and the position information of the part removal mobile robot 25. This allows the robot control unit 26 to share the control of the part removal mobile robot 25, thereby reducing the processing load of the information management unit 28.

[0095] [Second embodiment] The configuration of the component storage 202 according to the second embodiment will be described with reference to Fig. 10. In the second embodiment, unlike the first embodiment, the storage structure 227 has multiple (two) unused component storage sections 27b. Note that in the second embodiment, detailed description of the same configuration as in the first embodiment will be omitted.

[0096] The configuration of a parts storage 202 according to the second embodiment of the present invention will be described with reference to FIG.

[0097] As shown in FIG. 10, a component mounting system 200 includes a component mounting line 1 and a component storage warehouse 202.

[0098] (Parts storage configuration) The parts storage 202 is configured to store the parts E in a state where the temperature, humidity, and the like inside the storage are appropriately adjusted. In the following description, as an example, the parts storage 202 in which the reel 3 is stored will be described.

[0099] The parts storage facility 202 includes a storage main body 21, an exit door 22, a display unit 23 (see FIG. 2), an operation unit 24 (see FIG. 2), a parts removal mobile robot 25, a robot control unit 26, a storage structure 227, and an information management unit 28.

[0100] Here, the up-down direction is the Z direction, the up direction is the Z1 direction, and the down direction is the Z2 direction. The horizontal direction toward the display unit 23 is the Y1 direction, and the horizontal direction opposite the display unit 23 is the Y2 direction. The direction perpendicular to the Z direction and the Y direction is the X direction, and one side of the X direction is the X1 direction, and the other side of the X direction is the X2 direction.

[0101] The storage structure 227 is configured to store reels 3, trays, and the like. Specifically, the storage structure 227 has a plurality of storage sections 27a and a plurality (two) of unused component storage sections 227b. Note that three or more unused component storage sections 227b may be provided. Also, the plurality of unused component storage sections 227b are an example of the "unused item storage section" in the claims.

[0102] <Parts-picking mobile robot> The part-picking mobile robot 25 is configured to, based on the unused part information Na based on the non-use condition C acquired from the information management unit 28, sort and transport the unused reels 4 to a plurality of unused part storage units 227b in accordance with the non-use condition C. The unused reels 4 are an example of the "unused part storage member" in the claims.

[0103] An example of sorting by the part-picking mobile robot 25 will be described below.

[0104] For example, the information management unit 28 may be configured to manage the unused part information Na by dividing the unused part information Na into storage addresses Ad of the unused part storage units 227b based on the part identification numbers Pi. As a result, the part-picking mobile robot 25 carries the unused reels 4 to each of the unused part storage units 27b by sorting them by storage address Ad.

[0105] The information management unit 28 may be configured to manage unused part information Na by dividing the unused part information Na into storage addresses Ad of the plurality of unused part storage units 227b based on whether the unused part information Na is a part E stored on a reel 3 or a part stored on a tray. As a result, the component removal mobile robot 25 carries the unused reel 4 to each of the plurality of unused part storage units 27b by separating the unused part information Na into parts E stored on a reel 3 and parts stored on a tray. The other configurations of the second embodiment are the same as those of the first embodiment.

[0106] (Effects of the second embodiment) In the second embodiment, similarly to the first embodiment, the component storage 202 includes an unused component storage section 27b in which a plurality of unused reels 4 are stored in a stacked state. This makes it possible to prevent a reduction in the number of storage sections 27a in which usable components are arranged.

[0107] In the second embodiment, as described above, a plurality of unused part storage sections 27b are provided. The part-picking mobile robot 25 is configured to, based on acquiring unused part information Na based on the unused condition C from the information management section 28, separate the unused reels 4 into a plurality of unused part storage sections 27b according to the unused condition C and transport the separated unused reels 4. This eliminates the need for the worker to separate the unused reels 4 collected in the unused part storage sections 27b when collecting the unused reels 4 from the unused part storage sections 27b, thereby suppressing an increase in the workload of the worker. Other effects of the second embodiment are similar to those of the first embodiment.

[0108] [Third embodiment] The configuration of a parts storage 302 according to the third embodiment will be described with reference to Fig. 11. In the third embodiment, unlike the first embodiment, the parts storage 302 has an unused parts storage section 27b separate from the multiple storage sections 327a. Note that in the third embodiment, detailed descriptions of the same configuration as in the first embodiment will be omitted.

[0109] The configuration of a parts storage 302 according to the third embodiment will be described with reference to FIG.

[0110] As shown in FIG. 11, a component mounting system 300 includes a component mounting line 1 and a component storage warehouse 302.

[0111] (Parts storage configuration) The parts storage 302 is configured to store the parts E in a state where the temperature, humidity, and the like inside the storage are appropriately adjusted. In the following description, as an example, the parts storage 302 in which the reel 3 is stored will be described.

[0112] The parts storage 302 includes a storage main body 21, an exit door 22, a display unit 23 (see FIG. 2), an operation unit 24 (see FIG. 2), a parts removal mobile robot 25, a robot control unit 26, a plurality of storage units 327a, an unused parts storage unit 327b, and an information management unit 28. The unused parts storage unit 327b is an example of the "unused item storage unit" in the claims.

[0113] Here, the up-down direction is the Z direction, the up direction is the Z1 direction, and the down direction is the Z2 direction. The horizontal direction toward the display unit 23 is the Y1 direction, and the horizontal direction opposite the display unit 23 is the Y2 direction. The direction perpendicular to the Z direction and the Y direction is the X direction, and one side of the X direction is the X1 direction, and the other side of the X direction is the X2 direction.

[0114] The unused part storage section 327b is provided separately from the plurality of storage sections 327a. The unused part storage section 327b is disposed closer to the confirmation window 21b than the plurality of storage sections 327a. The other configurations of the third embodiment are the same as those of the first embodiment.

[0115] (Effects of the third embodiment) In the third embodiment, as in the first embodiment, the component storage 302 includes an unused component storage section 327b in which a plurality of unused reels 4 are stored in a stacked state. This makes it possible to prevent a decrease in the number of storage sections 27a in which usable components are arranged. Other advantages of the third embodiment are the same as those of the first embodiment.

[0116] [Fourth embodiment] The configuration of a component storage 402 according to the fourth embodiment will be described with reference to Fig. 12. Unlike the first embodiment, the fourth embodiment includes a component storage 402 having a light detection unit 429. Note that in the fourth embodiment, detailed description of the same configuration as in the first embodiment will be omitted.

[0117] The configuration of a parts storehouse 402 according to the fourth embodiment will be described with reference to FIG.

[0118] As shown in FIG. 12, a component mounting system 400 includes a component mounting line 1 and a component storage warehouse 402.

[0119] (Parts storage configuration) The parts storage 402 is configured to store parts E in a state where the temperature, humidity, and the like inside the storage are appropriately adjusted. In the following description, as an example, the parts storage 402 in which the reel 3 is stored will be described.

[0120] The parts storage 402 includes a storage main body 21, an exit door 22, a display unit 23 (see FIG. 2), an operation unit 24 (see FIG. 2), a parts removal mobile robot 25, a robot control unit 26, a storage structure 27, an information management unit 28, a light detection unit 429, and a notification unit 430. The unused parts storage unit 327b is an example of the "unused item storage unit" in the claims.

[0121] Here, the up-down direction is the Z direction, the up direction is the Z1 direction, and the down direction is the Z2 direction. The horizontal direction toward the display unit 23 is the Y1 direction, and the horizontal direction opposite the display unit 23 is the Y2 direction. The direction perpendicular to the Z direction and the Y direction is the X direction, and one side of the X direction is the X1 direction, and the other side of the X direction is the X2 direction.

[0122] The light detection unit 429 is configured to detect, by light, whether or not the unused reel 4 is at a predetermined height position in the unused part storage unit 27b. The light detection unit 429 has a light emitting element and a light receiving element.

[0123] The notification unit 430 is configured to notify the operator when the light detection unit 429 detects that the unused reel 4 is at a predetermined height position. The notification unit 430 is configured to notify the operator by at least one of light and sound.

[0124] In this way, the operator can check whether the unused reels 4 are full in the unused component storage section 27b not only from the storage state of the unused reels 4 displayed on the display section 23 but also from the notification section 430. The other configurations of the fourth embodiment are the same as those of the first embodiment.

[0125] (Effects of the fourth embodiment) In the fourth embodiment, similarly to the first embodiment, the component storage 402 includes an unused component storage section 27b in which a plurality of unused reels 4 are stored in a stacked state. This makes it possible to prevent a reduction in the number of storage sections 27a in which usable components are arranged.

[0126] In the fourth embodiment, as described above, the component storage 402 includes a light detector 429 that detects whether the unused reel 4 is at a predetermined height in the unused component storage section 27b by light. This allows the worker to check the storage state of the unused reel 4 not only by the number of times the unused reel 4 has been carried to the unused component storage section 27b by the component removal mobile robot 25, but also by the height position of the unused reel 4 in the unused component storage section 27b detected by the light detector 429. As a result, the worker can accurately know the storage state of the unused reel 4 in the unused component storage section 27b.

[0127] In the fourth embodiment, as described above, the component storage 402 includes a notification unit 430 that notifies an operator when the light detection unit 429 detects that the unused reel 4 is at a predetermined height. This allows the operator to be sure of the storage state of the unused component storage unit 27b, thereby ensuring that the operator can collect the unused reel 4 from the unused component storage unit 27b. Other effects of the fourth embodiment are similar to those of the first embodiment.

[0128] [Variations] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is indicated by the claims, not by the description of the embodiments above, and further includes all modifications (variations) within the meaning and scope of the claims.

[0129] For example, in the above first to fourth embodiments, the part storage warehouse 2 (202, 302, 402) is an example of a warehouse that stores part E, but the present invention is not limited to this. In the present invention, as in a first modified example shown in Fig. 13, the part storage warehouse 502 may be an automated warehouse including an autonomous vehicle 525. The autonomous vehicle 525 has a vehicle body 525a and a Z-axis movement mechanism 525b that moves the vehicle body 525a in the Z direction.

[0130] In the fourth embodiment, the component storage 402 is provided with the light detector 429, but the present invention is not limited to this. In the present invention, as in the second modified example shown in FIG. 14, the component storage 602 is provided with a weight measuring device 629 that measures the total weight of unused reels 4 carried to the unused component storage section 27b. This allows the worker to check the storage state of the unused reels 4 not only by the number of times the component removal mobile robot 25 has carried the unused reels 4 to the unused component storage section 27b, but also by the total weight of the unused reels 4 measured by the weight measuring device 629. As a result, the worker can accurately know the storage state of the unused reels 4 in the unused component storage section 27b.

[0131] The parts storage 602 also includes a notification unit 630 that notifies an operator when the measurement result of the weight measuring device 629 exceeds a threshold value. This allows the operator to know the storage state of the unused parts storage unit 27b before the unused parts storage unit 27b becomes full of unused parts N, thereby preventing the unused parts storage unit 27b from becoming full of unused parts N.

[0132] In the above first to fourth embodiments, the moisture limit C1 and oxidation limit C2 (first limit) and the warranty limit C3 (second limit) are set for each part identification number Pi, but the present invention is not limited to this. In the present invention, the first limit and the second limit may be set for each reel identification number, etc.

[0133] In the above first to fourth embodiments, the part E that satisfies the non-use condition C is the unused part N, but the present invention is not limited to this. In the present invention, the unused part may be a part that does not need to be stored in the part storage, or a part that is not used frequently in the part mounting device, and is therefore not suitable for the purpose of the part storage.

[0134] In the above first to fourth embodiments, the information management unit 28 is configured to manage information about one part stocker 2 (202, 302, 402) by way of example, but the present invention is not limited to this. In the present invention, the information management unit may be configured to manage information about a plurality of part stockers.

[0135] In the above first to fourth embodiments, the robot control unit 26 controls the movement of the part-picking mobile robot 25, but the present invention is not limited to this. In the present invention, the information management unit may control the movement of the part-picking mobile robot.

[0136] In the above first to fourth embodiments, the information management unit 28 is configured to automatically select unused reels 4 periodically, but the present invention is not limited to this. In the present invention, the parts storage may notify the worker of the time to select unused reels by a notification unit (for example, a patrol lamp, etc.). In this case, the worker manually selects unused parts in the information management unit.

[0137] In the above first to fourth embodiments, the information management unit 28 acquires the part information Ea based on the information of the barcode or QR code attached to the reel 3, but the present invention is not limited to this. In the present invention, the information management unit may acquire the part information based on information managed in software stored in another control device.

[0138] In the above first to fourth embodiments, the component storage 2 (202, 302, 402) stores the component E, but the present invention is not limited to this. In the present invention, the component storage may store not only components but also items including jigs such as backup pins. That is, the component storage includes a plurality of storage sections for storing storage members in which items used for mounting a board or for board mounting work are stored. The component storage includes a take-out mobile robot for taking out the storage members stored in each of the plurality of storage sections and carrying them to a delivery position. The component storage includes an unused item storage section in which unused item storage members that store unused items that are not selected as items to be delivered from the delivery position among the storage members stored in each of the plurality of storage sections are carried by the take-out mobile robot and in which a plurality of unused item storage members are stored in a stacked state. In this way, by evacuating the unused item storage members to the unused item storage sections, it is possible to ensure the number of storage sections capable of storing storage members by the number of stacked unused item storage members, compared to a case in which unused item storage members remain in each of the multiple storage sections. As a result, it is possible to prevent a reduction in the number of multiple storage sections.

[0139] In the above first to fourth embodiments, the non-use condition C includes the moisture limit C1 and the oxidation limit C2 (first limit), the warranty limit C3 (second limit), and the undetermined use condition, but the present invention is not limited to this. In the present invention, the non-use condition may include at least one of the first limit, the second limit, and the undetermined use condition.
