Description

Parts storage system and parts storage method

This specification discloses a technology related to a parts storage system and a parts storage method.

The electronic component mounting system described in Patent Document 1 includes an exposure time management section and a mounting line control section. The exposure time management unit counts the exposure time of the parts subject to humidity control being exposed to the atmosphere in units of reels, and records the accumulated exposure time. The mounting line control unit compares the exposure time with the exposure limit time set for the humidity controlled component, and identifies the electronic component mounter equipped with the reel of the humidity controlled component that has exceeded the exposure limit time, based on the location information. At the same time, the work by the electronic component mounting apparatus is stopped. If the location information registered for the reel of the humidity-controlled part is information about a dry box in which electronic parts are stored in a low-humidity environment, the exposure time management section sets the exposure time for the humidity-controlled part. Stop timing.

The storage unit stores the target part in an automated warehouse based on the remaining time managed by the management unit so as not to run out of the remaining time of the target part.

This specification also discloses a parts storage method comprising a management process and a storage process. The management step manages the remaining time from when the target part, which is the part mounted on the substrate and requires humidity control, is exposed to the atmosphere until it reaches a specified time that can be used in production. . The storage step causes the automated warehouse to store the target part based on the remaining time managed by the managing step so as not to run out of the remaining time of the target part.

　According to the above parts storage system, it has a management section and a storage section. As a result, the parts storage system can store the target parts in the automated warehouse while appropriately managing the remaining time that can be used in the production of the target parts that require humidity control.

The storage member 21 enters the automated warehouse 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 can also be provided at different openings.

The reading device 31 is provided above the work space 34a near the entrance 30a. The reading device 31 reads the identification code (for example, the identification code 23a, the identification code 23b) attached to the stored member 21 when the stored member 21 is stored in the automated warehouse 30, and reads the stored member 21. Acquire identification information that identifies the As the reading device 31, a known reading device (for example, a code reader that reads a one-dimensional code, a two-dimensional code, etc.) can be used. If the identification code is a wireless tag, the automated warehouse 30 can be equipped with a wireless device capable of wirelessly communicating with the identification code.

The control device 32 includes a known arithmetic device and storage device, and constitutes a control circuit. The control device 32 is also communicably connected to the reading device 31, the display device 33, the transfer device 35, the humidity adjustment device 36, and the temperature adjustment device 37, and can control them. For example, controller 32 may control reader 31 . Also, the control device 32 can acquire the identification information acquired by the reading device 31 from the reading device 31 .

Furthermore, the control device 32 is provided so as to be able to communicate with the management device 19 and the parts management device 70 shown in FIG. 1 through a wired or wireless communication unit. For example, the management device 19 notifies the control device 32 of occurrence of a setup change in the board-related work line 10L. The management device 19 can also notify the control device 32 of the shortage of the storage members 21 to be supplied to the board-related work line 10L. The management device 19 can also notify the control device 32 of the possibility that a setup change will occur during a predetermined period. The management device 19 can also notify the control device 32 of the possibility that the storage members 21 will run short during a predetermined period. Based on these notifications, the control device 32 unloads the necessary storage members 21 .

A known display device can be used for the display device 33, and various information is displayed so that the operator can visually recognize it. The display device 33 displays, for example, member information indicating information related to the accommodation member 21 accommodated in the accommodation portion 34 in accordance with the operator's operation. The component information can include, for example, the component type, model, inventory quantity, and the like. Further, the member information can include the type, model, vendor name, remaining number, humidity control level, expiration date, etc. of the parts 91 accommodated in the accommodation member 21 .

The display device 33 of this embodiment is configured by a touch panel, and the display device 33 also functions as an input device that receives various operations by the operator. For example, the operator can specify a desired storage member 21 to be delivered from the automated warehouse 30 using a touch panel (display device 33 functioning as an input device). In this case, the control device 32 unloads the designated storage member 21 .

What has already been described about the containing member 21 can be similarly applied to the containing case containing at least one containing member 21 . However, in this case, when housing the housing member 21 in the housing case, the operator uses a code reader of a portable terminal device or the like to read the identification code attached to the housing case and the identification code attached to the housing member 21. read the identification code. As a result, the identification information for identifying the storage case and the identification information for identifying the storage member 21 are associated and stored in the storage device of the parts management device 70 .

The reading device 31 reads the identification code attached to the storage case when the storage case is stored, and acquires identification information for identifying the stored storage case. The control device 32 acquires the identification information of the storage member 21 stored in the storage case that has entered the automated warehouse 30 from the correspondence relationship of the identification information stored in the storage device of the parts management device 70 . Thereby, the control device 32 can recognize the storage member 21 stored in the storage case that has entered the automated warehouse 30 .

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

A plurality of storage spaces 34b1 and 34b2 can be provided along the vertical direction (Z-axis direction). For example, the size (width, depth and height) of the storage space 34b1 is set so that the storage member 21 can be stored therein. The size (width dimension, depth dimension and height dimension) of the storage space 34b2 is set so that the storage case that stores the storage member 21 can be stored therein.

The transfer device 35 is provided inside the plurality of storage units 34b when viewed in the vertical direction (Z-axis direction), and grips and moves the storage member 21 or the storage case. The transfer device 35 may take various forms as long as it can hold and move the storage member 21 or the storage case. For the transfer device 35, for example, a known robot arm (articulated robot), an elevation slide mechanism, or the like can be used.

The transfer device 35 has a gripping portion that grips the storage member 21 or the storage case carried into the work space 34a from the entrance 30a at the time of warehousing. The transfer device 35 moves the gripping portion to a predetermined storage space, and releases the gripping of the storage member 21 or storage case by the gripping portion. As a result, the storage member 21 or the storage case is stored in the predetermined storage space. In addition, the transfer device 35 has a gripping portion that grips the storage member 21 or the storage case stored in the predetermined storage space at the time of unloading. The transfer device 35 moves the gripping portion to the work space 34a and releases the gripping of the storage member 21 or the storage case by the gripping portion. This allows the storage member 21 or the storage case to be carried out. The loading and unloading of the storage member 21 or the storage case may be performed by an operator, or may be performed by an automatic guided vehicle or the like.

For example, the components 91 housed in the housing member 21 include resin-sealed components 91 . When the component that has been exposed to the atmosphere for more than a specified time and has absorbed the moisture in the atmosphere is heated in the reflow furnace 10d shown in FIG. There is Parts 91 with such high humidity sensitivity are called MSL (Moisture Sensitivity Level) parts, and the time during which they can be exposed to the atmosphere (the time during which they can be used in production) is specified for each type of part.

In this specification, the component 91 that is mounted on the board 90 and that requires humidity control is referred to as a target component 91t. The automated warehouse 30 of this embodiment includes a humidity control device 36 . The humidity adjusting device 36 can keep the storage unit 34 at a predetermined atmospheric humidity (below the predetermined humidity defined by the humidity control level of the target part 91t), and the automated warehouse 30 keeps the target part 91t at the predetermined atmospheric humidity. can be stored in Therefore, by storing the target part 91t in the automated warehouse 30, the countdown of the remaining time during which the target part 91t can be used in production can be stopped.

In addition, the automated warehouse 30 of this embodiment includes a temperature adjustment device 37. The temperature adjustment device 37 can keep the storage unit 34 at a predetermined ambient temperature (predetermined temperature defined by the humidity control level of the target component 91t), and the automated warehouse 30 keeps the target component 91t at a predetermined ambient temperature. can be stored. The ambient temperature in the room of the production equipment is often kept at a predetermined temperature defined by the humidity control level of the target part 91t. In this case, the automatic warehouse 30 can also omit the temperature adjustment device 37 .

1-4. shelf 40, dry box 50 and oven 60
The shelf 40 can place the housing member 21 or the housing case. Unlike the automated warehouse 30, the shelf 40 is not sealed, and stores the storage member 21 or the storage case at the ambient temperature and humidity in the room of the production facility. The shelf 40 can have storage space similar to the storage section 34 of the automated warehouse 30 . Arrangement of the storage space is not limited and can take various forms.

The dry box 50 is equipped with a humidity control unit that maintains a predetermined atmospheric humidity in the chamber, and can store the storage member 21 or the storage case at a predetermined atmospheric humidity. The dry box 50 can store the target component 91t at the ambient humidity specified by the humidity control level of the target component 91t. Therefore, similarly to the automatic warehouse 30, by storing the target part 91t in the dry box 50, the countdown of the remaining time during which the target part 91t can be used in production can be stopped.

When the target part 91t exceeds the remaining time available for production, the remaining time available for production can be recovered by drying the target part 91t for a specified time at a specified ambient temperature. . The predetermined ambient temperature, the predetermined time, and the number of times the drying can be performed are defined for each humidity control level of the target component 91t.

The oven 60 has a drying section that dries and maintains the inside of the chamber to a predetermined atmospheric humidity, and can dry the housing member 21 or the housing case to the predetermined humidity and store it at the predetermined atmospheric humidity. The oven 60 can dry and store the target component 91t under the conditions specified by the humidity control level of the target component 91t. Therefore, by storing the target part 91t in the oven 60, it is possible to recover the remaining time during which the target part 91t can be used in production.

1-5. Parts management device 70
The parts management device 70 manages the location of the parts 91 . Specifically, the parts management device 70 manages the location of the housing member 21 that houses the parts 91 . The production facility shown in FIG. 1 includes a warehouse area ZA1, a picking area ZA2 and an outside setup area ZA3. The warehouse area ZA1 is an area for storing parts 91 (accommodating members 21) for a longer period than the picking area ZA2, and includes at least one automated warehouse 30 (one in the figure).

The picking area ZA2 is an area for temporarily storing the parts 91 (accommodating members 21), and includes at least one shelf 40 (two in the figure). Parts 91 (accommodating members 21) stored in the automated warehouse 30 in the warehouse area ZA1 are conveyed to the picking area ZA2. The parts 91 (accommodating members 21) stored in the automated warehouse 30 in the warehouse area ZA1 can also be transported to the external setup area ZA3.

The outside setup area ZA3 includes at least one (one in the figure) shelf 40, at least one (one in the figure) dry box 50, and at least one (one in the figure) oven 60. and In the outside setup area ZA3, the parts 91 (accommodating members 21) transported from the warehouse area ZA1 can be stored on the shelf 40, the dry box 50, or the oven 60. In the outside setup area ZA3, the parts 91 (accommodating members 21) conveyed from the picking area ZA2 can also be stored on the shelf 40, the dry box 50, or the oven 60.

In addition, in the external setup area ZA3, for example, the reel 21a and the feeder 22a are combined to perform supply preparation work to enable supply to the board-to-board work line 10L. For example, an operator equips the feeder 22a with the reel 21a. At this time, the worker reads the identification code 23a attached to the reel 21a using, for example, a code reader of a mobile terminal. Also, the operator reads the identification code 24a attached to the feeder 22a using a code reader or the like of the mobile terminal.

As a result, the identification information identifying the reel 21 a and the identification information identifying the feeder 22 a are transmitted to the parts management device 70 . When acquiring the identification information, the parts management device 70 associates the identification information of the reel 21a with the identification information of the feeder 22a and stores them in the storage device. Further, the parts management device 70 updates the location information of the reel 21a, for example, when the reel 21a is moved.

For example, when moving the reel 21a, the worker reads the identification code 23a using a code reader of a portable terminal device. When the mobile terminal device has a positioning function, the mobile terminal device transmits the location information of the reel 21a to the parts management device 70 upon reading the identification code 23a. The parts management device 70 updates the location information of the reel 21a stored in the storage device to the received location information. Similarly, the parts management apparatus 70 can update the location information of the feeder 22a, for example, when the feeder 22a is moved.

The worker can also read the location codes provided in the warehouse area ZA1, the picking area ZA2, and the external setup area ZA3 using a code reader or the like of the mobile terminal. As a result, the location information of the area in which the read location code is provided is transmitted to the parts management device 70 . The worker can also read the location codes provided in the storage devices such as the automated warehouse 30, the shelves 40, the dry box 50 and the oven 60 using a code reader of a mobile terminal. As a result, the location information of the storage device provided with the read location code is transmitted to the parts management device 70 . Furthermore, the storage device can also transmit the position information to the parts management device 70 .

Also, in the external setup area ZA3, for example, a release operation for releasing the combination of the reel 21a and the feeder 22a that are no longer used in the production of the board-to-board work line 10L is performed as necessary. A worker, for example, takes out the reel 21a from the feeder 22a. The removed reel 21a is stored in a predetermined storage device, and the feeder 22a is stored in a predetermined storage device. In this case, the correspondence relationship between the identification information of the reel 21a and the identification information of the feeder 22a stored in the storage device is deleted. Moreover, when there is no need to cancel the combination, the reel 21a and the feeder 22a are stored in a predetermined storage device in a combined state. In this case, the correspondence relationship between the identification information of the reel 21a and the identification information of the feeder 22a stored in the storage device is maintained.

1-6. Parts storage system 80
In this way, the containing member 21 containing the component 91 moves from place to place in the production facility shown in FIG. Therefore, for example, every time a target part 91t requiring humidity control enters and leaves the automated warehouse 30, the worker registers the arrival and departure time of the target part 91t, and the remaining time during which the target part 91t can be used in production. If you try to manage , the registration work becomes complicated, and work mistakes such as omission of registration and erroneous registration are likely to occur.

The management unit 81 determines the remaining time from when the target component 91t, which is the component 91 mounted on the board 90 and requires humidity control, is exposed to the atmosphere until it reaches the specified time that can be used in production. to manage. The management unit 81 may take various forms as long as it can manage the remaining time.

As described above, the target part 91t absorbs moisture in the atmosphere by being exposed to the atmosphere, and the remaining time is reduced. Therefore, the management unit 81 preferably starts counting down the remaining time when the package of the target part 91t is opened in the arrival unit 20 and the predetermined work is performed. For example, the worker attaches an identification code (for example, the identification code 23a attached to the reel 21a) to the accommodation member 21 that accommodates the target component 91t.

Then, the worker reads the identification code attached to the housing member 21 using a code reader or the like of the mobile terminal. As a result, the identification information for identifying the containing member 21 containing the target component 91t is transmitted to the parts management device 70 and stored in the storage device of the parts management device 70 . The management unit 81 can start counting down the remaining time of the target part 91t housed in the housing member 21 when the identification information for identifying the housing member 21 housing the target part 91t is acquired.

The operator or the parts management device 70 determines whether or not the part 91 accommodated in the accommodation member 21 is the target part 91t. (for example, a flag), the identification information and the humidity control level are stored in the storage device of the parts management device 70 . For example, the operator or the parts management device 70 refers to a database in which article information (information on the parts 91 accommodated in the accommodation member 21) regarding the accommodation member 21 is registered, and It can be determined whether or not the part 91 is the target part 91t. The operator or the parts management device 70 can refer to the database to acquire the identification information and the humidity management level of the target part 91t.

Also, while the target part 91t is stored in the automated warehouse 30 or the dry box 50, the management unit 81 stops counting down the remaining time during which the target part 91t can be used in production. Furthermore, when the target part 91t is stored in the oven 60 or the baking process is performed in the automated warehouse 30, the management unit 81 resets the remaining time during which the target part 91t can be used for production. specified time), increase the number of times of drying by one, and store it in the storage device.

The storage unit 82 stores the target part 91t in the automated warehouse 30 based on the remaining time managed by the management unit 81 so that the remaining time of the target part 91t does not run out. The storage unit 82 may take various forms as long as it can store the target part 91t in the automated warehouse 30 so that the remaining time of the target part 91t does not run out.

Specifically, the storage unit 82 can store the target part 91t in the automated warehouse 30 under predetermined conditions defined by the humidity control level of the target part 91t. Thereby, the automated warehouse 30 can appropriately store the target part 91t. For example, the storage unit 82 can store the target part 91t in the automated warehouse 30 at a humidity level equal to or lower than a predetermined humidity defined by the humidity control level of the target part 91t.

As described above, the automated warehouse 30 is equipped with the humidity control device 36. The storage unit 82 drives and controls the humidity adjustment device 36 to reduce the atmospheric humidity of the storage unit 34 of the automatic warehouse 30 to a predetermined humidity or less specified by the humidity control level of the target part 91t, and the The part 91t can be stored.

In addition, the storage unit 82 can store the target part 91t in the automated warehouse 30 at a predetermined temperature defined by the humidity control level of the target part 91t. As already mentioned, the automated warehouse 30 is equipped with the temperature control device 37 . The storage unit 82 drives and controls the temperature adjustment device 37 to set the ambient temperature of the storage unit 34 of the automatic warehouse 30 to a predetermined temperature defined by the humidity control level of the target component 91t, and the target component is stored in the automatic warehouse 30. 91t can be stored.

Note that the humidity control level differs depending on the type of the target component 91t, and the remaining time (maximum time) of the target component 91t also differs. In addition, the target part 91t may be exposed to the atmosphere during the period from when it leaves the automated warehouse 30 until it enters the automated warehouse 30 again, and the remaining time of the target part 91t may decrease. be. Therefore, the management unit 81 stores identification information for identifying the target part 91t, the humidity control level of the target part 91t, the entry time when the target part 91t entered the automated warehouse 30, and the delivery time when the target part 91t left the automated warehouse 30. Based on the time, it can be determined whether or not the remaining time of the target component 91t has expired.

As described above, the automated warehouse 30 is equipped with a reading device 31. The reader 31 reads the identification code attached to the storage member 21 and obtains identification information for identifying the stored storage member 21 . The management unit 81 refers to the storage device of the parts management device 70 to check whether information (e.g., a flag) indicating that the parts 91 stored in the received storage member 21 are the target parts 91t is stored. determine whether or not If the storage device stores information indicating that the part is the target part 91 t , the management unit 81 determines that the target part 91 t has entered the automated warehouse 30 . In this case, the management section 81 acquires the identification information and the humidity management level from the storage device. If the storage device does not store information indicating that the part is the target part 91t, the management unit 81 determines that the normal part 91 that is not the target part 91t has been stocked in the automated warehouse 30 .

In addition, the control device 32 of the automated warehouse 30 causes the storage device of the automated warehouse 30 to store the position information, incoming/outgoing information, and storage information of the storage member 21 or storage unit 34 of the storage case. The position information includes information indicating the storage location of the storage member 21 or the storage case. The warehousing/delivery information includes information indicating the warehousing time and the warehousing time of the storage member 21 or the storage case. The storage information includes at least information about the ambient humidity out of the ambient temperature and the ambient humidity of the storage section 34 . The control device 32 causes the storage device to store the position information and the arrival time when the storage member 21 or the storage case is stored. The control device 32 causes the storage device to store storage information while the storage member 21 or the storage case is being stored. The control device 32 stores the delivery time in the storage device when the storage member 21 or the storage case is delivered.

The management unit 81 acquires the time when the target part 91t entered the automated warehouse 30 and the time when the target part 91t left the automated warehouse 30 from the incoming/outgoing information stored in the storage device of the automated warehouse 30. can be obtained. In addition, the management unit 81 calculates the first time from the delivery time when the target part 91t leaves the automated warehouse 30 to the arrival time when the target part 91t enters the automated warehouse 30 again.

The management unit 81 determines that the remaining time of the target part 91t has expired when the first time is longer than the remaining time of the target part 91t at the time of delivery (accumulated time during which the target part 91t is exposed to the atmosphere). can do. Further, the management unit 81 can determine that the remaining time of the target part 91t has not expired when the first time is equal to or less than the remaining time of the target part 91t at the time of delivery (step S11 and step shown in FIG. 5). S12). The management unit 81 can determine whether or not the remaining time has expired for each target component 91t.

Further, when the target part 91t is stored in the dry box 50 after leaving the automated warehouse 30 and before entering again, the management unit 81 subtracts the time stored in the dry box 50 from the first time. do. Furthermore, when the target part 91t is stored in the oven 60 after leaving the automatic warehouse 30 and before entering again, the management unit 81 starts the target part 91t from the delivery time when the target part 91t leaves the oven 60. is stored in the automated warehouse 30 and is calculated as the first time.

1-6-2. Selector 83
The selection unit 83 specifies the warehousing regulation that prevents the target part 91t from entering the automatic warehouse 30 when the target part 91t is stored in the automatic warehouse 30 and the remaining time has expired, or the humidity control level of the target part 91t. Execution of the baking process for storing the target part 91t in the automatic warehouse 30 under the predetermined conditions is selected.

In the above case, the selection unit 83 may take various forms as long as it is possible to select the execution of the warehousing regulation or the baking process for the target part 91t. For example, as shown in FIG. 6, the selection unit 83 can display a selection screen on the display device 33 of the automated warehouse 30 to allow the worker to select warehousing regulation of the target part 91t or execution of the baking process ( If Yes in step S12 shown in FIG. 5 and step S13). FIG. 6 schematically shows a state in which a worker is prompted to select either suspension of warehousing (warehousing regulation) or baking processing, together with a display indicating that the time available for production of the warehousing target part 91t has passed. ing.

It should be noted that the selection unit 83 can also select, for example, in the control settings of the automated warehouse 30, whether to restrict the entry of the target part 91t or to perform the baking process. If the remaining time has not expired when the target part 91t is stored in the automated warehouse 30, the storage unit 82 permits the storage of the target part 91t and stores the target part 91t in the automated warehouse 30 (see FIG. 5). If No in step S12 shown and step S14).

When the execution of the baking process is selected, the storage unit 82 executes the baking process (if Yes in step S15 and step S16 shown in FIG. 5). Specifically, the storage unit 82 causes the automated warehouse 30 to store the target part 91t under predetermined conditions defined by the humidity control level of the target part 91t. For example, the storage unit 82 can store the target part 91t in the automated warehouse 30 for a predetermined time or longer at a predetermined humidity or less defined by the humidity control level of the target part 91t. As already mentioned, the automated warehouse 30 is equipped with the humidity control device 36 . The storage unit 82 drives and controls the humidity adjustment device 36 to reduce the atmospheric humidity in the storage unit 34 of the automatic warehouse 30 to a predetermined humidity or less specified by the humidity control level of the target part 91t, and automatically maintains the humidity for a predetermined time or longer. The warehouse 30 can store the target part 91t.

Further, the storage unit 82 can store the target part 91t in the automated warehouse 30 for a predetermined time or more at a predetermined temperature defined by the humidity control level of the target part 91t. As already mentioned, the automated warehouse 30 is equipped with the temperature control device 37 . The storage unit 82 drives and controls the temperature adjustment device 37 to set the ambient temperature of the storage unit 34 of the automatic warehouse 30 to a predetermined temperature defined by the humidity control level of the target part 91t, and maintains the temperature in the automatic warehouse for a predetermined time or longer. 30 can store the target part 91t.

Note that if the target component 91t is not heat-resistant for baking due to the packing state (stick, tape, tray, etc.) of the target component 91t, the storage unit 82 transfers the target component 91t to a heat-resistant container and executes the baking process. be able to. In addition, when the target component 91t is not heat-resistant in the baking process due to the packaging state of the target component 91t, the storage unit 82 lowers the ambient temperature of the storage unit 34 to room temperature (for example, 25° C. to 35° C.), and stores the target component. 91t can also be stored. In this case, the time required for baking is longer than baking at a high temperature (for example, 100° C. or higher).

Further, as shown in FIG. 3B, the storage unit 34 of the present embodiment is provided in one sealed area, and the target parts 91t stored in the plurality of storage units 34b are baked under the same conditions. . Therefore, the storage unit 82 stores the target part 91t in the automatic warehouse 30 under the conditions (the above-described predetermined humidity or less, for example, 5% or less) in which the target part 91t with the strictest humidity control level can be baked. can be done. Further, when the production facility includes a plurality of automated warehouses 30, the storage unit 82 can also allocate the automated warehouses 30 that store the target parts 91t for each humidity control level of the target parts 91t.

Furthermore, as shown in FIG. 7, the storage section 34 can also be provided in a plurality of (eight in the figure) closed areas partitioned by partition members 34c. A storage unit 34b is provided in each of the plurality (eight) sealed areas. The partition member 34 c has an opening/closing portion 34 d on the side facing the transfer device 35 . In the figure, for convenience of illustration, some of the partition members 34c and some of the opening/closing portions 34d are given reference numerals, and not all members are provided with reference numerals. In addition, in the closed area where the work space 34a is provided, a storage unit 34b is provided above or below the work space 34a.

The opening/closing part 34d is controlled to be in an open state when the storage member 21 or the storage case is put in or taken out, and the storage member 21 or the storage case can be put in or taken out. The opening/closing part 34d is controlled to be in a closed state except when entering/leaving the vehicle. As a result, one automated warehouse 30 can store a plurality of types of target parts 91t with different humidity control levels under different conditions. In addition, one automated warehouse 30 can bake a plurality of types of target parts 91t with different humidity control levels under different conditions.

It should be noted that, when warehousing regulation of the target part 91t is selected, the storage unit 82 carries out warehousing regulation of the target part 91t (if No in step S15 and step S17 shown in FIG. 5). In this case, for example, the worker or the automatic guided vehicle unloads the target part 91t whose entry is restricted and which is placed in the work space 34a. The storage unit 82 can also execute the baking process without selection by the selection unit 83 .

1-6-3. Calculation unit 84
The calculation unit 84 calculates the time required for the baking process when performing the baking process for storing the target part 91t in the automated warehouse 30 under the predetermined conditions defined by the humidity control level of the target part 91t. The humidity control level differs depending on the type of the target component 91t, and the remaining time (maximum time) of the target component 91t also differs. In addition, the longer the remaining time of the target part 91t is exceeded, the longer the time required for the baking process tends to be. Furthermore, the higher the atmospheric humidity of the storage section 34, the longer the time required for the baking process.

Therefore, the calculation unit 84 calculates the identification information for identifying the target part 91t, the humidity control level of the target part 91t, the excess time exceeding the remaining time of the target part 91t, and the storage unit for storing the target part 91t in the automated warehouse 30. Based on the atmospheric humidity of 34, the time required for the baking process is calculated (step S18 shown in FIG. 5). The relationship between the excess time and the required time and the relationship between the atmospheric humidity and the required time can be acquired in advance by simulation, verification using an actual machine, or the like.

The time required for baking calculated by the calculator 84 can be used in various controls by the parts storage system 80 . For example, if the baking process is interrupted in the middle, it becomes difficult to determine the moisture absorption state of the target component 91t. Therefore, the storage unit 82 can restrict the delivery of the target part 91t from the automated warehouse 30 during the time from the start of the baking process to the elapse of the time required for the baking process (the step shown in FIG. 5). S19).

Also, for example, when the target part 91t undergoing the baking process is waiting for delivery, there is a demand to know the remaining time until the required time for the baking process elapses. Therefore, the storage unit 82 can also guide the remaining time until the required time for the baking process elapses (step S20 shown in FIG. 5). The storage unit 82 may take various forms as long as it can guide the remaining time. For example, the storage unit 82 can display the remaining time until the time required for the baking process elapses on the display device 33 of the automated warehouse 30 .

It is assumed that the target part 91t used in other production equipment is used in the production equipment shown in FIG. In this case, the moisture absorption state of the target component 91t is often unknown. Therefore, the storage unit 82 executes the baking process for storing the target part 91t in the automated warehouse 30 for the first time in the automated warehouse 30 under the predetermined conditions defined by the humidity control level of the target part 91t. can be done. As a result, the remaining time during which the target part 91t can be used in production can be reset (set to the prescribed time during which the target part 91t can be used in production).

In addition, the number of times the baking process can be executed (synonymous with the number of times the drying can be performed) is defined for the target part 91t. Therefore, the storage unit 82 can also allow the operator or the like to input the number of baking processes (the number of times of drying) performed before the storage. Furthermore, the baking process for the target component 91t that is to be stored in the automated warehouse 30 for the first time is not limited to the form in which the component storage system 80 includes the calculation unit 84 . The baking process can be performed in the same manner as the baking process already described in any of the forms already described.

1-6-4. Common part 85
As described above, the operator or the parts management device 70 can determine whether or not the part is the target part 91t. Further, acquisition of the humidity management level of the target component 91t can be performed by the operator or the component management device 70. FIG. For example, for a component 91 that has been determined to be the target component 91t by the component management device 70 and for which the humidity control level has been acquired, the operator determines whether it is the target component 91t, acquires the humidity control level, When registered in the automated warehouse 30, redundant work is performed.

In addition, the automated warehouse 30 can acquire the arrival time when the target part 91t entered the automated warehouse 30 and the delivery time when the target part 91t left the automated warehouse 30. In this case, for example, if the worker registers the entry time when the target part 91t entered the automated warehouse 30 and the delivery time when the target part 91t left the automated warehouse 30 in the parts management device 70, the registration work becomes complicated. As a result, work errors such as omission of registration and erroneous registration are likely to occur.

Therefore, the sharing unit 85 shares predetermined information between the parts management device 70 that manages the target part 91t and the automated warehouse 30 (step S21 shown in FIG. 5). The predetermined information includes identification information for identifying the target part 91t, the humidity control level of the target part 91t, the arrival time when the target part 91t entered the automated warehouse 30, and the delivery time when the target part 91t left the automated warehouse 30. At least the identification information and the humidity control level should be included.

Specifically, as shown in FIG. 1, the parts management device 70 and the automated warehouse 30 are provided to communicate with each other via a wired or wireless communication unit. The sharing unit 85 allows the control device 32 of the automated warehouse 30 to access predetermined information owned by the parts management device 70 . Further, the sharing unit 85 permits the parts management device 70 to access predetermined information owned by the automated warehouse 30 . Further, the sharing unit 85 can centrally manage predetermined information using a database or the like. In this case, sharing unit 85 allows parts management device 70 and automated warehouse 30 to access predetermined information stored in the database.

Similarly, information on whether or not the remaining time of the target part 91t has expired is preferably shared between the parts management device 70 and the automated warehouse 30. Information on whether or not the baking process for storing the target part 91t under the predetermined conditions defined by the humidity control level of the target part 91t has been executed is shared between the parts management device 70 and the automated warehouse 30. is preferred. Note that the baking process in this case is not limited to the baking process in the automated warehouse 30 . For example, the baking process described above includes baking in oven 60 .

Further, information as to whether or not the automated warehouse 30 can store the target part 91t under the predetermined conditions defined by the humidity control level of the target part 91t is shared between the parts management device 70 and the automated warehouse 30. preferably Therefore, the sharing unit 85 can share at least one of the above information between the parts management device 70 and the automated warehouse 30 . Also, the sharing unit 85 can guide at least one of the above information. For example, the sharing unit 85 can display at least one of the above information on the display device 33 of the automated warehouse 30 .

2. Parts Storage Method What has already been described for the parts storage system 80 can be applied to the parts storage method as well. Specifically, the parts storage method includes a management process and a storage process. The control performed by the management unit 81 corresponds to a management process. The control performed by the storage section 82 corresponds to the storage process. The parts storage method can also comprise a selection step. The control performed by the selection unit 83 corresponds to the selection step. The parts storage method can also comprise a calculation step. The control performed by the calculator 84 corresponds to the calculation process. The component storage method may also comprise shared steps. The control performed by the sharing unit 85 corresponds to the sharing process.
