[0001] The present invention relates to a method and system for manufacturing a product. [Background technology]

[0002] Conventionally, a system has been known in which a warehouse is installed within a clean room of a building and dust-sensitive items are stored in the warehouse (see, for example, Patent Document 1). Patent Document 1 discloses that, as needed, the items are removed from the warehouse and subjected to a predetermined processing or treatment, and then either transported out of the clean room or temporarily stored back in the warehouse. Patent Document 1 discloses that the clean warehouse is installed below the floor wall of the clean room to eliminate the reduction in floor space that would result from installing a warehouse within the clean room. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-144503 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the warehouse is installed inside a clean room, which requires equipment to maintain the cleanliness of the entire large space including the warehouse, resulting in increased equipment installation costs.On the other hand, if the warehouse is installed outside the clean room, it will be exposed to a general space where the cleanliness of dust-sensitive items cannot be maintained, making it impossible to maintain the cleanliness of the manufactured items.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a manufacturing method and manufacturing system for manufactured products that can assemble manufactured products while maintaining the cleanliness of objects that have been washed in a clean room, while preventing an increase in installation costs due to the installation of a warehouse in the clean room. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following means. A method for manufacturing a product according to one aspect of the present invention includes a first transfer step of transporting a storage container containing objects to be cleaned to a first storage position of an automated warehouse; a second transfer step of transporting the storage container from the first storage position to a first clean room in which a cleaning device is installed; a cleaning step of cleaning the objects to be cleaned removed from the storage container transported by the second transfer step using the cleaning device and storing the sealed container in the storage container; a third transfer step of transporting the storage container containing the sealed container from the first clean room to a second storage position of the automated warehouse; a fourth transfer step of transporting the storage container from the second storage position to a second clean room having an assembly area for assembling the objects to be cleaned; and an assembly step of removing the objects to be cleaned from the sealed container stored in the storage container transported to the second clean room by the fourth transfer step and assembling the objects to be cleaned in the assembly area to manufacture a product.

[0007] According to a manufacturing method of a product according to one aspect of the present invention, a storage container containing objects to be cleaned is transported to a first storage position of an automated warehouse in a first transport step. The objects to be cleaned are removed from the storage container transported from the first storage position to a first clean room in a second transport step, cleaned by a cleaning device in a cleaning step, placed in a sealed container, and stored in the storage container together with the sealed container.

[0008] In the third transfer process, the storage container containing the sealed container is transferred from the first clean room to the second storage position of the automated warehouse. In the third transfer process, the storage container is transferred from the first clean room to the general environment where the automated warehouse is located, but because the cleaned objects to be cleaned are contained in sealed containers, the cleanliness of the objects to be cleaned stored in the automated warehouse can be maintained.

[0009] In the fourth transport step, the storage container containing the sealed container is transported from the second storage position to the second clean room, and in the assembly step, the objects to be cleaned taken out of the sealed container are assembled into a finished product in the assembly area. In this way, the objects to be cleaned that have been cleaned in the first clean room can be stored in an automated warehouse located in an external general environment, and can be transported to the second clean room as needed and assembled into a finished product.

[0010] As described above, according to the method for manufacturing a product according to one aspect of the present invention, it is possible to assemble a product while maintaining the cleanliness of the objects to be cleaned in the clean room, while preventing an increase in installation costs due to the installation of a warehouse in the clean room.

[0011] In one embodiment of the method for manufacturing a product of the present invention, a plurality of the objects to be cleaned may be stored in the storage container, and a fifth transport process may be provided in which the storage container containing the sealed container containing the objects to be cleaned other than the objects to be cleaned used in the assembly process is transported from the second clean room to a third storage position in the automated warehouse.

[0012] According to the manufacturing method for manufactured products configured as described above, only a portion of the multiple cleaning objects stored in the storage container that are to be used in the assembly process can be removed from the sealed container, and the remaining cleaning objects can be properly stored in an automated warehouse while maintaining their cleanliness.

[0013] In one aspect of the present invention, in a method for manufacturing a product, the storage container has a first main body portion that stores the sealed container and has a first opening that opens upward, and a first lid portion that is attached to the top of the first main body portion so as to seal the first opening, and the fourth transport process may be configured to blow air toward the first lid portion when the storage container passes through an airlock chamber that is located between a storage space in which the automated warehouse is located and the second clean room.

[0014] According to the manufacturing method for a product configured as described above, the first opening formed in the first main body of the storage container facing upward is sealed with the first lid, thereby preventing dust from entering the inside of the first main body of the storage container stored in the automated warehouse. Furthermore, in the fourth transfer step, air is blown toward the first lid of the storage container passing through the airlock chamber, so that the storage container can be transferred to the second clean room in a state where dust that has accumulated on the first lid during storage in the automated warehouse has been removed, thereby preventing dust from entering the second clean room.

[0015] In the method for manufacturing a product having the above configuration, the sealed container may have a second main body portion that accommodates the object to be cleaned and has a second opening that opens upward, a second lid portion that is attached to the top of the second main body portion to seal the second opening, and a holding portion that maintains the sealed state in which the second opening is sealed by the second lid portion, and the upper surface of the second main body portion has a protrusion that is formed endlessly to surround the second opening and protrudes upward, and the second lid portion has an elastic member attached to it that contacts the protrusion and elastically deforms when sealing the second opening, and when the sealed state is maintained by the holding portion, the protrusion and the elastic member come into contact to form an endless sealed area that surrounds the second opening.

[0016] According to the method for manufacturing a product of the above aspect, the second opening formed in the second body portion of the sealed container facing upward is sealed with the second lid portion, and this state is maintained by the retaining portion. Furthermore, when the sealed state is maintained by the retaining portion, the protrusion of the second body portion and the elastic member of the second lid portion come into contact with each other to form an endless sealed area surrounding the second opening. Therefore, the cleanliness of the inside of the sealed container can be reliably maintained while it is stored in the automated warehouse.

[0017] In a method for manufacturing a product according to one aspect of the present invention, the first clean room and the second clean room may be located on the same floor of a building, and the automated warehouse may be located on a floor above or below the first clean room and the second clean room.

[0018] According to the manufacturing method for manufactured products configured as described above, by locating the first clean room and the second clean room on the same floor of the building and locating the automated warehouse on a floor above or below them, it is possible to reduce the building area required for storing the items to be cleaned and manufacturing the products.

[0019] A manufacturing system according to one aspect of the present invention comprises a first clean room in which a cleaning device for cleaning objects is installed, a second clean room having an assembly area for assembling the objects cleaned by the cleaning device to manufacture products, an automated warehouse that stores a storage container in which the objects to be cleaned are stored at a predetermined storage position and transports the storage container to a predetermined destination, and a control device that controls the transportation of the storage container in the automated warehouse, wherein the control device controls the transportation of the storage container in which the objects to be cleaned manufactured in the processing chamber are stored to a first storage position in the automated warehouse, and the transportation of the storage container from the first storage position to the first clean room, the transportation of the storage container containing a sealed container that contains the objects to be cleaned cleaned by the cleaning device from the first clean room to a second storage position in the automated warehouse, and the transportation of the storage container from the second storage position to the second clean room.

[0020] According to a manufacturing system of one aspect of the present invention, a storage container containing objects to be cleaned is transported to a first storage position in an automated warehouse. The objects to be cleaned are removed from the storage container transported from the first storage position to a first clean room, cleaned by a cleaning device, and placed in a sealed container, which is then stored together with the sealed container in the storage container.

[0021] The storage container containing the sealed containers is transported from the first clean room to the general environment where the automated warehouse is located, but the cleaned objects are still contained in the sealed containers, so the cleanliness of the objects stored in the automated warehouse can be maintained.

[0022] The container containing the sealed container is transported from the second storage position to the second clean room, and the object to be cleaned removed from the sealed container is assembled into a product in the assembly area. In this way, the object to be cleaned cleaned in the first clean room can be stored in an automated warehouse located in an external general environment, and can be transported to the second clean room as needed and assembled into a product.

[0023] As described above, according to the manufacturing system of one aspect of the present invention, it is possible to assemble products while maintaining the cleanliness of objects cleaned in the clean room, while preventing an increase in installation costs due to the installation of a warehouse in the clean room.

[0024] In a manufacturing system according to one aspect of the present invention, the storage container transported to the first storage position may contain a plurality of the objects to be cleaned, and the control device may be configured to control the storage container storing the sealed container containing the objects to be cleaned other than the objects to be cleaned used in the assembly area to be transported from the second clean room to a third storage position in the automated warehouse.

[0025] According to the manufacturing system configured as described above, only a portion of the multiple cleaning objects stored in the storage container that are to be used in the assembly area can be removed from the sealed container, and the remaining cleaning objects can be properly stored in the automated warehouse while maintaining their cleanliness.

[0026] In a manufacturing system according to one aspect of the present invention, the storage container may have a first main body portion that stores the sealed container and has a first opening that opens upward, and a first lid portion that is attached to the top of the first main body portion so as to seal the first opening, and may also have an airlock space that is located between a storage space in which the automated warehouse is located and the second clean room, and a blowing device that blows air toward the first lid portion as the storage container passes through the airlock space.

[0027] According to the manufacturing system for manufactured products configured as described above, the first opening formed in the first main body of the storage container facing upward is sealed by the first lid, thereby preventing dust from entering the inside of the first main body of the storage container while it is stored in the automated warehouse. Also, because air is blown toward the first lid of the storage container passing through the airlock chamber, the storage container can be transported to the second clean room with dust that accumulates on the first lid while it is stored in the automated warehouse removed, thereby preventing dust from entering the second clean room.

[0028] In the manufacturing system of the above configuration, the sealed container may have a second main body portion that accommodates the object to be cleaned and has a second opening that opens upward, a second lid portion that is attached to the top of the second main body portion to seal the second opening, and a holding portion that maintains the sealed state in which the second opening is sealed by the second lid portion, and the upper surface of the second main body portion has a protrusion that is formed endlessly to surround the second opening and protrudes upward, and the lower surface of the second lid portion has an elastic member attached that contacts the protrusion and elastically deforms when sealing the second opening, and when the sealed state is maintained by the holding portion, the protrusion and the elastic member come into contact to form an endless sealed area that surrounds the second opening.

[0029] According to the manufacturing system of the above aspect, the second opening formed in the second body portion of the sealed container facing upward is sealed by the second lid portion, and this state is maintained by the retaining portion. Furthermore, when the sealed state is maintained by the retaining portion, the protrusion of the second body portion and the elastic member of the second lid portion come into contact with each other to form an endless sealed area surrounding the second opening. Therefore, the cleanliness of the inside of the sealed containers stored in the automated warehouse can be reliably maintained.

[0030] In a manufacturing system according to one aspect of the present invention, the first clean room and the second clean room may be located on the same floor of a building, and the automated warehouse may be located on a floor above or below the first clean room and the second clean room.

[0031] According to the manufacturing system configured as described above, by locating the first clean room and the second clean room on the same floor of the building and locating the automated warehouse on a floor above or below them, the building area required for storing the items to be cleaned and manufacturing the products can be reduced. [Effects of the Invention]

[0032] According to the present invention, it is possible to provide a manufacturing method and manufacturing system for manufactured products that can assemble products while maintaining the cleanliness of objects cleaned in a clean room, while preventing an increase in installation costs due to the installation of a warehouse in a clean room.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0034] A manufacturing system 100 according to one embodiment of the present invention will be described below with reference to the drawings. The manufacturing system 100 of this embodiment is a system that processes raw materials such as resin materials (fluororesin materials, etc.) to manufacture a processed product (object to be cleaned) P, cleans the manufactured processed product P, and then assembles it with other parts to manufacture a finished product G.

[0035] 1, the manufacturing system 100 includes a processing chamber 10, a first clean room 20, a second clean room 30, an automated warehouse 40, a control device 50, a first airlock chamber 60, and a second airlock chamber 70. As shown in FIG. 1, in the manufacturing system 100, the first clean room 20 and the second clean room 30 are located on a second floor 102 on the same floor of a building.

[0036] On the other hand, the processing chamber 10 and the automated warehouse 40 are arranged on the first floor surface 101, which is the floor below the first clean room 20 and the second clean room 30. The processing chamber 10 and the automated warehouse 40 may also be arranged on the floor above the first clean room 20 and the second clean room 30.

[0037] The processing chamber 10 is a room where a processing device 11 is installed that processes raw materials to produce processed products P. The processing device 11 produces processed products P, for example, by cutting or drilling a resin material, which is the raw material. The processing device 11 may be, for example, a device that molds a resin material into a desired shape by injection molding. The multiple processed products P produced by the processing device 11 are stored in a storage container C1 by an operator (not shown).

[0038] The first clean room 20 is a room where a cleaning device 21 for cleaning the processed product P is installed. The first clean room 20 is also equipped with a ventilation device 22 that maintains the internal space 20a at a positive pressure higher than atmospheric pressure and filters particulate matter floating in the internal space 20a. The ventilation device preferably has a performance such that the cleanliness class of the internal space 20a is Class 7 or lower according to ISO14644-1:2015, for example.

[0039] The cleaning device 21 is a device that cleans the workpiece P multiple times with a cleaning liquid (e.g., pure water). An operator places the workpiece P, which has been cleaned and dried by the cleaning device 21, in an airtight container C2 in the first clean room 20 so that it is not in communication with the outside. By storing the workpiece P in the airtight container C2, the interior of the airtight container C2 can be maintained at a cleanliness equivalent to that of the internal space 20a of the first clean room 20, even when the storage container C1 that stores the airtight container C2 is stored in a general environment (cleanliness level of Class 8 or higher in ISO14644-1:2015) in which the automated warehouse 40 is located.

[0040] The second clean room 30 is a room having an assembly area A where workers assemble the processed product P, which has been cleaned by the cleaning device 21 and housed in the sealed container C2, together with other parts. The workers take out the processed product P from the sealed container C2 housed in the storage container C1 transported from the automated warehouse 40 to the second clean room 30, and assemble it with the other parts to produce the finished product G.

[0041] The second clean room 30 is equipped with a ventilation device 31 that maintains the internal space 30a at a positive pressure higher than atmospheric pressure and filters particulate matter suspended in the internal space 30a. The ventilation device preferably has a performance that ensures that the cleanliness of the internal space 30a is Class 7 or lower according to ISO14644-1:2015, for example.

[0042] The automated warehouse 40 is a device that stores a storage container C1 in which processed products are stored at a predetermined storage location and transports the storage container C1 to a predetermined destination. As shown in Fig. 1, the automated warehouse 40 has a plurality of storage locations S for storing the storage containers C1. The plurality of storage locations S are partitioned by a plurality of vertical frames 41 and a plurality of horizontal frames 42.

[0043] The automated warehouse 40 has storage positions S in four rows along the vertical direction VD, eleven rows along the horizontal direction HD, and a predetermined number of rows (not shown) in the depth direction. The automated warehouse 40 has a moving mechanism (not shown) that moves a storage container C1 stored in a predetermined storage position S to another arbitrary storage position S.

[0044] The automated warehouse 40 has a lifting mechanism 43 that moves the storage container C1 taken out from each storage position S to any position along the vertical direction VD, and a conveying mechanism 44 that moves the storage container C1 along the horizontal direction HD along a horizontal frame 42 that is positioned at the highest position in the vertical direction VD.

[0045] The control device 50 is a device that controls the transportation of the storage container C1 in the automated warehouse 40. The control device 50 controls the movement mechanism to move the storage container C1 stored in a predetermined storage position S to another arbitrary storage position S. The control device 50 also controls the lifting mechanism 43 to move the storage container C1 taken out from each storage position S to an arbitrary position in the vertical direction. The control device 50 also controls the transport mechanism 44 to move the storage container C1 along the horizontal direction HD.

[0046] The first airlock chamber 60 is a chamber provided between the internal space 20a, which is maintained at a positive pressure higher than atmospheric pressure, and the general environment, which is at atmospheric pressure and in which the automated warehouse 40 is located, for adjusting the pressure difference between the internal space 20a and the general environment. The first airlock chamber 60 has an opening / closing door 61, an opening / closing door 62, and an air shower (spraying device) 63, each of which is controlled by the control device 50.

[0047] When transporting the containment vessel C1 from the general environment to the internal space 20a, the control device 50 opens the open-close door 61 while keeping the open-close door 62 closed, and transports the containment vessel C1 into the first airlock chamber 60. After transporting the containment vessel C1 into the first airlock chamber 60, the control device 50 closes the open-close door 61 and operates the air shower 63 for a predetermined time. The air shower 63 blows air onto the containment vessel C1 to remove dust adhering to the containment vessel C1.

[0048] Thereafter, the control device 50 opens the opening / closing door 62 while keeping the opening / closing door 61 closed, and carries the storage container C1 into the first clean room 20. After carrying the storage container C1 into the first clean room 20, the control device 50 closes the opening / closing door 62.

[0049] When transporting the containment vessel C1 from the internal space 20a to the general environment, the control device 50 carries the containment vessel C1 into the first airlock chamber 60 with the open door 62 in an open state and the open door 61 in a closed state. After carrying the containment vessel C1 into the first airlock chamber 60, the control device 50 closes the open door 62 and then opens the open door 61. After carrying the containment vessel C1 out of the first airlock chamber 60, the control device 50 closes the open door 61.

[0050] The second airlock chamber 70 is a chamber provided between the internal space 30a, which is maintained at a positive pressure higher than atmospheric pressure, and the general environment, which is at atmospheric pressure and in which the automated warehouse 40 is located, for adjusting the pressure difference between the internal space 30a and the general environment. The second airlock chamber 70 has an opening / closing door 71, an opening / closing door 72, and an air shower (spraying device) 73, each of which is controlled by the control device 50.

[0051] When transporting the containment vessel C1 from the general environment to the internal space 30a, the control device 50 opens the door 71 while keeping the door 72 closed, and transports the containment vessel C1 into the second airlock chamber 70. After transporting the containment vessel C1 into the second airlock chamber 70, the control device 50 closes the door 71 and operates the air shower 73 for a predetermined time. The air shower 73 blows air onto the containment vessel C1 to remove dust adhering to the containment vessel C1.

[0052] Thereafter, the control device 50 opens the opening / closing door 72 while keeping the opening / closing door 71 closed, and carries the storage container C1 into the second clean room 30. After carrying the storage container C1 into the second clean room 30, the control device 50 closes the opening / closing door 72.

[0053] When transporting the containment vessel C1 from the internal space 30a to the general environment, the control device 50 carries the containment vessel C1 into the second airlock chamber 70 with the open door 72 in an open state and the open door 71 in a closed state. After carrying the containment vessel C1 into the second airlock chamber 70, the control device 50 closes the open door 72 and then opens the open door 71. After carrying the containment vessel C1 out of the second airlock chamber 70, the control device 50 closes the open door 71.

[0054] Next, a manufacturing method executed by the manufacturing system 100 of this embodiment will be described with reference to the drawings. Fig. 2 is a flowchart showing a manufacturing method for a product according to one embodiment of the present invention. The control device 50 executes a control program stored in a storage unit (not shown), thereby performing each process shown in Fig. 2.

[0055] In step S101, the control device 50 determines whether an operator of the manufacturing system 100 has issued an instruction to manufacture the processed product P. If YES, the process proceeds to step S102, and if NO, the process proceeds to step S104.

[0056] In step S102 (processing step), the control device 50 controls the processing device 11 installed in the processing chamber 10 to manufacture a processed product P. In step S102, the control device 50 transmits a manufacturing instruction for the processed product P to the processing device 11 installed in the processing chamber 10. An operator in the processing chamber 10 feeds raw materials into the processing device 11 according to the manufacturing instruction displayed on a display unit (not shown) of the processing device 11. The operator stores one or more processed products P manufactured by the processing device 11 in a storage container C1.

[0057] In step S103 (first transport step), the control device 50 controls the automated warehouse 40 to transport the storage container C1 storing the processed product P to a first storage position S1 of the automated warehouse 40. The first storage position S1 can be any position among the multiple storage positions S that the automated warehouse 40 has.

[0058] In step S104, the control device 50 determines whether an operator of the manufacturing system 100 has issued an instruction to clean the processed product P, and if YES, the process proceeds to step S105, and if NO, the process proceeds to step S108.

[0059] In step S105 (second transfer process), the control device 50 controls the automated warehouse 40 to transfer the storage container C1 from the first storage position S1 to the first clean room 20 in which the cleaning device 21 is installed. The control device 50 transfers the storage container C1 from the first storage position S1 to the first airlock chamber 60, and then transfers the storage container C1 from the first airlock chamber 60 to the internal space 20a of the first clean room 20.

[0060] When passing through the first airlock chamber 60, air is blown toward the first lid C1b (see FIGS. 3 to 5) of the containment vessel C1 by the air shower 63. Dust accumulated in the containment vessel C1 is removed by the air blown by the air shower 63.

[0061] In step S106 (cleaning process), the control device 50 controls the cleaning device 21 installed in the first clean room 20 so that the cleaning device 21 cleans the workpiece P removed from the storage container C1. In step S106, the control device 50 transmits an instruction to the cleaning device 21 to clean the workpiece P. An operator in the first clean room 20 places the workpiece P removed from the storage container C1 into the cleaning device 21 in accordance with the cleaning instruction displayed on a display unit (not shown) of the cleaning device 21.

[0062] An operator places one or more processed products P cleaned by the cleaning device 21 into the sealed container C2. The operator also stores the sealed container C2 in the storage container C1. The sealed container C2 is a container for isolating the cleaned processed products P from the outside so as to maintain a cleanliness equivalent to that of the internal space 20a of the first clean room 20. The structure of the sealed container C2 will be described later.

[0063] In step S107 (third transport step), the control device 50 controls the automated warehouse 40 to transport the storage container C1 storing the sealed container C2 to a second storage position S2 of the automated warehouse 40. The second storage position S2 can be any position among the multiple storage positions S that the automated warehouse 40 has.

[0064] In step S108, the control device 50 determines whether an operator of the manufacturing system 100 has issued an instruction to pick the processed product P, and if YES, proceeds to step S109, and if NO, ends the processing of this flowchart.

[0065] In step S109 (fourth transfer process), the control device 50 controls the automated warehouse 40 to transfer the storage container C1 from the second storage position S2 to the second clean room 30 having an assembly area A for assembling the processed product P together with other parts. The control device 50 transfers the storage container C1 from the second storage position S2 to the second airlock chamber 70, and then transfers the storage container C1 from the second airlock chamber 70 into the internal space 30a of the second clean room 30.

[0066] When passing through the second airlock chamber 70, air is blown toward the first lid C1b (see FIGS. 3 to 5) of the containment vessel C1 by the air shower 73. Dust accumulated in the containment vessel C1 is removed by the air blown by the air shower 73.

[0067] In step S110 (assembly process), a worker removes the processed product P from the sealed container C2 stored in the storage container C1 transported to the second clean room 30. The worker then assembles the processed product P with other parts in the assembly area A to manufacture the product G. If the number of processed products P used in assembling the product G is smaller than the number of processed products P stored in the sealed container C2 transported to the second clean room 30, the worker stores the sealed container C2 containing the other processed products P excluding the used processed products P in the storage container C1.

[0068] In step S111 (fifth transfer step), the control device 50 controls the automated warehouse 40 to transfer the storage container C1 storing the sealed container C2 to a third storage position S3 of the automated warehouse 40. The third storage position S3 can be any position among the multiple storage positions S of the automated warehouse 40. After executing step S111, the control device 50 ends the processing of this flowchart.

[0069] Next, the structures of the storage container C1 and the sealed container C2 of this embodiment will be described with reference to the drawings. Fig. 3 is a front view showing the storage container C1 that stores the processed product P, showing a state in which the sealed container C2 is housed inside. Fig. 4 is a cross-sectional view of the storage container C1 and the sealed container C2 shown in Fig. 3. Fig. 5 is a cross-sectional view showing a state in which the first lid C1b is removed from the storage container C1 shown in Fig. 4 and the second lid C2b is removed from the sealed container C2.

[0070] 3 to 5, the storage container C1 has a first main body C1a, a first lid C1b, and a first holding portion C1c, and is made of, for example, a resin material. The first main body C1a is a housing that houses the sealed container C2 and has a first opening C1aA that opens upward in the vertical direction VD.

[0071] The first lid portion C1b is a member attached to the upper part of the first main body portion C1a so as to seal the first opening C1aA. The first holding portion C1c is a member that maintains the first opening C1aA sealed by the first lid portion C1b. The first holding portion C1c is fixed to the first main body portion C1a and fixes the first lid portion C1b to the first main body portion C1a in a state in which the first opening C1aA is sealed by the first lid portion C1b.

[0072] 4 and 5, the upper surface of the first main body portion C1a is provided with a first protrusion C1aB that is formed endlessly and protrudes upward to surround the first opening C1aA.

[0076] According to the method for manufacturing the product G using the manufacturing system 100 of this embodiment described above, the following actions and effects are achieved. According to the manufacturing method of this embodiment, the processed product P manufactured by the processing device 11 is stored in the storage container C1 and transported to the first storage position S1 of the automated warehouse 40. The processed product P is removed from the storage container C1 and transported from the first storage position S1 to the first clean room 20, cleaned by the cleaning device 21, placed in the sealed container C2, and stored together with the sealed container C2 in the storage container C1.

[0077] The storage container C1 containing the sealed container C2 is transported from the first clean room 20 to the general environment where the automated warehouse 40 is located, while the cleaned processed products P are contained in the sealed container C2. Therefore, the cleanliness of the processed products P stored in the automated warehouse 40 can be maintained.

[0078] The storage container C1 containing the sealed container C2 is transported from the second storage position S2 to the second clean room 30, and the processed product P removed from the sealed container C2 is assembled into the finished product G in the assembly area A. In this way, the processed product P cleaned in the first clean room 20 can be stored in the automated warehouse 40 located in the general external environment, and can be transported to the second clean room 30 as needed and assembled into the finished product G.

[0079] As described above, according to the manufacturing method of this embodiment, it is possible to assemble products while maintaining the cleanliness of the processed products P washed in the clean room, while preventing an increase in installation costs due to the installation of a warehouse in the clean room.

[0080] Furthermore, according to the manufacturing method of this embodiment, only a portion of the processed products P to be used in the assembly area A among the multiple processed products P stored in the storage container C1 can be removed from the sealed container C2, and the remaining processed products P can be appropriately stored in the automated warehouse 40 while maintaining the cleanliness of the remaining processed products P.

[0081] Furthermore, according to the manufacturing method of this embodiment, the first opening C1aA formed in the first main body C1a of the storage container C1 facing upward is sealed with the first lid C1b, thereby preventing dust from entering the inside of the first main body C1a of the storage container C1 while it is stored in the automated warehouse 40. Furthermore, air is blown toward the first lid C1b of the storage container C1 passing through the second airlock chamber 70, so that dust that accumulates on the first lid C1b while it is stored in the automated warehouse 40 can be removed before the storage container C1 is transported to the second clean room 30, preventing dust from entering the second clean room 30.

[0082] According to the manufacturing method of this embodiment, the second opening C2aA formed in the second main body C2a of the sealed container C2 facing upward is sealed by the second lid C2b, and this state is maintained by the second retaining portion C2c. Furthermore, when the sealed state is maintained by the second retaining portion C2c, the second protrusion C2aB of the second main body C2a and the second packing C2bA of the second lid C2b come into contact with each other to form an endless second sealed region surrounding the second opening C2aA. This ensures that the cleanliness of the sealed container C2 during storage in the automated warehouse 40 is maintained.

[0083] Furthermore, according to the manufacturing method of this embodiment, by arranging the first clean room 20 and the second clean room 30 on the same floor of the building and arranging the automated warehouse 40 on a floor above or below them, the building construction area required for storing the processed products P and manufacturing the finished products G can be reduced.

[0084] Other Embodiments In the above description, the workpiece P processed in the processing chamber 10 is stored in the storage container C1, and then the workpiece P is transported to the first clean room 20 and cleaned by the cleaning device 21. However, other embodiments are also possible. For example, the object to be cleaned that is transported to the first clean room 20 and cleaned by the cleaning device 21 may be a part other than the workpiece P processed in the processing chamber 10.

[0085] Specifically, the object to be cleaned may be an externally manufactured object, such as an O-ring or other part that is one of the parts assembled into the product G. If the product G is a fluid device that circulates a liquid inside, any part that comes into contact with the liquid when the product G is in use can be the object to be cleaned.

[0086] In the above description, when the storage container C1 is maintained in a sealed state by the first retaining portion C1c, the first protrusion C1aB and the first packing C1bA come into contact with each other to form an endless first sealed area surrounding the first opening C1aA. However, other configurations are also possible. For example, the storage container C1 may not include the first protrusion C1aB, the first packing C1bA, and the first retaining portion C1c. In this case, the storage container C1 has the first lid C1b superimposed on the top surface of the first main body C1a. Furthermore, the storage container C1 may include only the first main body C1a and not the first lid C1b.

[0087] Furthermore, a conductive resin material may be used as the material for forming the containment vessel C1 and the sealed vessel C2 described above. By using a conductive resin material as the material for the vessels, static electricity accumulated in the components housed inside the vessels can be discharged to the outside, preventing damage to the components due to static electricity. For example, a conductive sheet may be placed on the bottom surface of the main body of the vessel, and a conductive portion may be used to electrically connect the conductive sheet to the outside of the vessel.
