Patent Description:
Some part-forming fixtures, such as a mandrel used during a process of fabricating a fuselage of an aircraft using composite materials, have multiple fluidic ports and conduits extending along the fixture. Hoses, which are individually connectable to the ports, are used to deliver heated air and/or air under negative pressure (e.g., a vacuum) to the fixture or a portion of the fixture, during a part-forming process.

Typically, the individual connection between each hose and port is tested, prior to the part-forming process, to ensure the connection quality at each connection (e.g., a quality of the vacuum). Individual hoses are manually connected and disconnected to the necessary ports during the testing and part-forming process, which is a time consuming and labor-intensive process. Additionally, the multiple hoses, which can range in quantity from the tens to hundreds, depending on the application, can become disorganized, create tripping hazards, and/or become unintentionally damaged during the testing or part-forming process. Furthermore, if the fixture requires any rotation, the hoses must be disconnected, prior to rotation of the fixture, and reconnected after rotation of the fixture, which can occur multiple times during a part-forming process. <CIT> discloses in its claim <NUM> a mandrel body outer surface having one or more fluid openings defined therein, and further comprising a mandrel body fluid system, said mandrel body fluid system comprising at least one fluid source capable of supplying pressurized fluid or a vacuum and one or more fluid lines coupled between said fluid source and said one or more fluid openings.

The described features, structures, advantages, and/or characteristics of the subject matter of the present disclosure may be combined in any suitable manner in one or more examples, including embodiments and/or implementations. In the following description, numerous specific details are provided to impart a thorough understanding of examples of the subject matter of the present disclosure.

The features and advantages of the subject matter of the present disclosure will become more fully apparent from the following description and appended claims, or may be learned by the practice of the subject matter as set forth hereinafter.

In order that the advantages of the subject matter may be more readily understood, a more particular description of the subject matter briefly described above will be rendered by reference to specific examples that are illustrated in the appended drawings. Understanding that these drawings depict only typical examples of the subject matter, they are not therefore to be considered to be limiting of its scope. The subject matter will be described and explained with additional specificity and detail through the use of the drawings, in which:.

Reference throughout this specification to "one example," "an example," or similar language means that a particular feature, structure, or characteristic described in connection with the example is included in at least one example of the present disclosure. Appearances of the phrases "in one example," "in an example," and similar language throughout this specification may, but do not necessarily, all refer to the same example. Similarly, the use of the term "implementation" means an implementation having a particular feature, structure, or characteristic described in connection with one or more examples of the present disclosure, however, absent an express correlation to indicate otherwise, an implementation may be associated with one or more examples.

In some examples, the present disclosure provides an apparatus for providing flowable material to a part-forming fixture. The part-forming fixture could be any apparatus or device on which a part is formed that requires the delivery of flowable material to the apparatus or device at some point during the part-forming process. For example, the part-forming fixture may be a mandrel that is used during a composite fuselage fabrication process. Generally, the process of attaching hoses, used to deliver flowable material (i.e., air, gas, or a vacuum (e.g., air at a pressure below atmospheric pressure)), to ports along the part-forming fixture is a time-consuming and labor-intensive process, as each individual hose is independently connected and disconnected to the part-forming fixture during any testing of the part-forming fixture or during the part-forming process. The apparatus of the present disclosure can be used to quickly connect and/or disconnect multiple hoses simultaneously rather than individually connecting and/or disconnecting each hose to the part-forming fixture. In some examples, the hoses can be organized into a hose management system to reduce unintentional damage to and the tripping hazards posed by disordered hoses. Additionally, in some examples, the apparatus has a rotatable joint that enables the apparatus to remain connected to the part-forming fixture while the part-forming fixture is being rotated. Referring to <FIG>, one example of a tool manifold <NUM> of an apparatus (see, e.g., <FIG>) is shown. The tool manifold <NUM> includes a tool-manifold base <NUM> that has a tool surface <NUM> and a fixture-interface surface <NUM>, opposite of the tool surface <NUM>. As shown, the tool-manifold base <NUM> has a circular shape, however, the tool-manifold base <NUM> could be any of various shapes and/or sizes. A plurality of tool fittings <NUM> (i.e., hose fittings) extend through the tool-manifold base <NUM>. Each tool fitting <NUM> has a hose end <NUM> that extends from the tool surface <NUM> of the tool-manifold base <NUM> and an interface end <NUM> that extends from the fixture-interface surface <NUM> of the tool-manifold base <NUM>. In one example, the hose end <NUM> of each of the plurality of tool fittings <NUM> have the same size and are configured to be removably connectable to hoses (not shown) having the same size. In other examples, the hose ends <NUM> of the plurality of tool fittings <NUM> have a variety of sizes and are configured to be removably connectable to hoses with different diameters. For example, some hoses may have a half inch diameter while other hoses have a three-fourths inch diameter. In some examples, the plurality of tool fittings <NUM> are capable of receiving multiple types of flowable material, such as, pressurized air, hot air and/or depressurized air (e.g., vacuum). In other examples, the plurality of tool fittings <NUM> are optimized to receive one type of flowable material. The plurality of tool fittings <NUM> may also be capable of receiving an electric current, such as a current that heats or cools air as it passes through the tool manifold <NUM>. For example, it may be desirable to flow cooler air to an exothermic portion of a part-forming fixture or flow warmer air across a cooler portion of the part-forming fixture.

The tool manifold <NUM> can, depending on the needs of the fixture, have any number of tool fittings <NUM> in the plurality of tool fittings <NUM>. In some examples, the number of tool fittings <NUM> is between two and one hundred. In other examples, the number of tool fittings <NUM> is between thirty and eighty.

Referring to <FIG> and <FIG>, an example of a fixture manifold <NUM> of the apparatus <NUM> is shown. The fixture manifold <NUM> includes a fixture-manifold base <NUM> that has a fixture surface <NUM>, as shown in <FIG>, and a tool-interface surface <NUM> that is opposite of the fixture surface <NUM>, as shown in <FIG>. In the illustrated example, the fixture-manifold base <NUM> has a circular shape. However, in other examples, the fixture-manifold base <NUM> could be any of various shapes and/or sizes. Generally, the fixture-manifold base <NUM> has the same approximate shape as the tool-manifold base <NUM>. A plurality of fixture fittings <NUM> (i.e., hose fittings) extend through the fixture-manifold base <NUM>. The fixture fittings <NUM> have a hose end <NUM> that extends from the fixture surface <NUM> of the fixture-manifold base <NUM> and an interface end <NUM> that extends from the tool-interface surface <NUM> of the fixture-manifold base <NUM>. In one example, the hose end <NUM> of the plurality of fixture fittings <NUM> have the same size and are configured to be removably connectable to hoses (not shown) having the same size. In other examples, the hose ends <NUM> of the plurality of fixture fittings <NUM> are sized differently and configured to be removably connectable to hoses with different sized diameters.

Each one of the plurality of tool fittings <NUM> of the tool manifold <NUM> corresponds with one of the plurality of fixture fittings <NUM> of the fixture manifold <NUM>. Accordingly, the number of tool fittings <NUM> of the tool manifold <NUM> is equal to the number of fixture fittings <NUM> of the fixture manifold <NUM>. The interface end <NUM> of each one of the plurality of tool fittings <NUM> is removably attachable to the interface end <NUM> of the corresponding one of the plurality of fixture fittings <NUM>, such that, when attached, a seal is created between the tool fitting <NUM> and the corresponding fixture fitting <NUM>. In one example, the interface end <NUM> of the plurality of tool fittings <NUM> have a male structure while the interface end <NUM> of the plurality of fixture fittings <NUM> have a female structure, such that the female end fits inside the male end. In other examples, the interface end <NUM> of the plurality of tool fittings <NUM> have a female structure and the interface end <NUM> of the plurality of fixture fittings <NUM> have a male structure. The interface end <NUM> of the tool fittings <NUM> and/or the interface end <NUM> of the fixture fittings <NUM> may have O-rings, either externally or internally, such that, when the tool fittings <NUM> are attached to the fixture fittings <NUM>, the O-rings help hold the fittings together and prevents leaking between the fittings by creating a seal. In some examples, the plurality of tool fittings <NUM> and the plurality of fixture fittings <NUM> are configured to slide together, when attaching, without locking the individual tool fittings <NUM> to the corresponding fixture fittings <NUM>. In other examples, the plurality of tool fittings <NUM> and the plurality of fixture fittings <NUM> have individual locking mechanisms, such as a nut or other fastener, that locks the corresponding tool fittings <NUM> and fixture fittings <NUM> together after they are attached.

In <FIG>, the apparatus <NUM> is shown with the tool manifold <NUM> attached to the fixture manifold <NUM>. In other words, the interface end <NUM> of each one of the plurality of tool fittings <NUM> is attached to the interface end <NUM> of the corresponding one of the plurality of fixture fittings <NUM>. By attaching each one of the plurality of tool fittings <NUM> to the corresponding plurality of fixture fittings <NUM> simultaneously, the tool manifold <NUM> and the fixture manifold <NUM> can be quickly connected to each other. Accordingly, any hoses attached to the hose end <NUM> of the plurality of tool fittings <NUM> are simultaneously prepared to deliver flowable materials to any ports on a part-forming fixture connected, via a hose to a fixture fitting <NUM>, once the tool manifold <NUM> and fixture manifold <NUM> are attached. In other words, multiple hoses can be simultaneously prepared to deliver flowable material to a fixture by attaching the tool manifold <NUM> to the fixture manifold <NUM>, thereby significantly reducing the time and labor involved with attaching individual hose to individual ports on a fixture.

To aid in the proper alignment of the tool manifold <NUM> to the fixture manifold <NUM>, alignment guides may be used. In one example, the tool manifold <NUM> has at least one first alignment guide <NUM> and the fixture manifold <NUM> has at least one second alignment guide <NUM>. In some examples, the first alignment guide <NUM> protrudes out from the fixture-interface surface <NUM> of the tool manifold <NUM> and is configured to extend through the second alignment guide <NUM> of the fixture manifold <NUM>, the second alignment guide <NUM> configured as an opening through the fixture manifold <NUM> and sized to fit the first alignment guide <NUM>. Accordingly, as the tool manifold <NUM> and the fixture manifold <NUM> are being connected, the first alignment guide <NUM> is aligned with the corresponding second alignment guide <NUM>, such that the first alignment guides <NUM> protrudes through the second alignment guides <NUM> as they are connected. Aligning the first alignment guide <NUM> with the second alignment guide <NUM> further aligns the plurality of tool fittings <NUM> with the corresponding one of the plurality of fixture fittings <NUM>, allowing the tool manifold <NUM> to be quickly aligned with and connectable to the fixture manifold <NUM>.

In some examples, the tool manifold <NUM> has a rotatable joint which allows the tool manifold <NUM> to co-rotate with a rotating fixture, when the tool manifold <NUM> is attached to the fixture manifold <NUM> on the fixture. As shown in <FIG>, the rotatable joint of the tool manifold <NUM> includes a rotary union <NUM> and a rotatable drum <NUM>. The rotary union <NUM> has a first section <NUM> and a second section <NUM>. The first section <NUM> is coupled to the second section <NUM>, such that the second section <NUM> is rotatable relative to the first section <NUM>. The first section <NUM> includes a plurality of inlet ports <NUM>, which are configured to be removably attachable to corresponding tool hoses (not shown). The second section <NUM> includes a plurality of outlet ports <NUM>, which are connected to the hose end <NUM> of a corresponding one of the plurality of tool fittings <NUM> via a corresponding secondary tool hose <NUM> (e.g., see, <FIG>). The rotatable drum <NUM> is attached, at a first end <NUM>, to the tool surface <NUM> of the tool-manifold base <NUM> and, at a second end <NUM>, to the second section <NUM> of the rotary union <NUM>, such that the second section <NUM> and the rotatable drum <NUM> are co-rotatable. Accordingly, as the rotatable drum <NUM> and the second section <NUM> of the rotary union <NUM> rotate relative the first section <NUM> and the tool hoses attached thereto, the secondary tool hoses <NUM> also rotate with the rotatable drum <NUM>.

In some examples, a support structure <NUM> may be used to support the tool manifold <NUM>. The rotatable drum <NUM> is fixed to the support structure <NUM>, such that the support structure <NUM> and the rotatable drum <NUM> co-rotate relative to the fixed first section <NUM> of the rotary union <NUM>. The support structure <NUM> may further include a tool platform <NUM> that helps support the tool manifold <NUM> and/or fixture manifold <NUM> and keep the rotatable drum <NUM> properly aligned with the first section <NUM> of the rotary union <NUM>.

The tool manifold <NUM> is attachable to the fixture manifold <NUM>, as shown in <FIG>. Similar to the process described above in reference to <FIG>, the interface end <NUM> of each one of the plurality of tool fittings <NUM> is removably attached to the interface end <NUM> of the corresponding one of the plurality of fixture fittings <NUM>. In some examples, the apparatus <NUM> includes a clamping mechanism <NUM> which is configured to selectively secure the tool manifold <NUM> and the fixture manifold <NUM> together after the interface end <NUM> of each one of the plurality of tool fittings <NUM> is attached to the interface end <NUM> of the corresponding one of the plurality of fixture fittings <NUM>.

In one example, the clamping mechanism <NUM> is attached to the support structure <NUM> and is configured to prevent the fixture manifold <NUM> from separating from the tool manifold <NUM> (such as via a clamping force). For example, the clamping mechanism <NUM> includes a contact arm <NUM>, which can be movable in some examples, that is configured to contact the fixture surface <NUM> of the fixture manifold <NUM> to prevent the fixture manifold <NUM> from separating from the tool manifold <NUM>. The contact arm <NUM> of the clamping mechanism <NUM> can be moved toward the fixture surface <NUM>, via a rotatable wheel or other tightening system, until the contact arm <NUM> contacts the fixture surface <NUM> of the fixture manifold <NUM> with enough clamping force to keep the fixture manifold <NUM> from separating from the tool manifold <NUM>. Additionally, the contact arm <NUM> can include a circular cam that rotates along and maintains the clamping force against the fixture manifold <NUM> as the fixture manifold <NUM> rotates. In other examples, the clamping mechanism <NUM> is a separate device that is clamped around the tool manifold <NUM> and fixture manifold <NUM>, such that the clamping mechanism <NUM> is in contact with the tool surface <NUM> of the tool manifold <NUM> and the fixture surface <NUM> of the fixture manifold <NUM>. In yet other examples, the clamping mechanism <NUM> is fixed, at one end, to the tool manifold <NUM> or the fixture manifold <NUM> and is capable of clamping another end around the fixture manifold <NUM> or tool manifold <NUM>, respectively, to selectively secure the tool manifold <NUM> and the fixture manifold <NUM>. The apparatus <NUM> may include more than one clamping mechanism <NUM>.

In <FIG>, a cross sectional view of one example of a tool manifold <NUM> attached to a fixture manifold <NUM> of a system <NUM> is shown. A tool hose <NUM> is attached to each one of the plurality of inlet ports <NUM>. At least one flowable-material source <NUM> is connected to each one of the tool hoses <NUM> to provide at least one type of flowable material through the tool manifold <NUM> and fixture manifold <NUM> to a plurality of fixture hoses <NUM>. The flowable-material source <NUM> may supply any of various flowable materials corresponding to the part being manufactured on the part-forming fixture <NUM>.

In some examples, the system <NUM> further includes a control system <NUM>. As shown in <FIG>, the control system <NUM> is communicatively coupled with the at least one flowable-material source <NUM> to control the flow of flowable material supplied by the at least one flowable-material source <NUM> to the connected tool hoses <NUM> and to the tool manifold <NUM>. The control and monitoring of the flowable-material source <NUM>, through the control system <NUM>, can be accomplished via operation of various devices of the flowable-material source <NUM>, such as solenoids <NUM>, pressure transducers <NUM>, and mass flow rate sensors <NUM>.

In some examples, the system <NUM> includes the solenoids <NUM>, which are attached to corresponding ones of the tool hoses <NUM> or secondary tool hoses <NUM>. The solenoids <NUM> can be operated to selectively turn on or off the flowable material to the connected tool hoses <NUM> or the secondary tool hose <NUM>. The system <NUM> may also include the pressure transducers <NUM> and the mass flow rate sensors <NUM>. Like the solenoids <NUM>, the pressure transducers <NUM> and mass flow rate sensors <NUM> are attached to corresponding ones of the tool hoses <NUM> or secondary tool hoses <NUM>. The pressure transducers <NUM> can be operated to monitor the vacuum level to a connected hose and the mass flow rate sensors <NUM> can be operated to monitor the air flow to a connected hose. In one example, a user can selectively control the solenoids <NUM>, pressure transducers <NUM> and/or mass flow rate sensors <NUM> manually. Alternatively, or additionally, the control system <NUM> can further control the use of any solenoids <NUM>, pressure transducers <NUM> and mass flow rate sensors <NUM> within the system <NUM>. Accordingly, the control system <NUM> can be used to control the flow of flowable material to individual tool hoses within the system <NUM>, without the need to individually connect or disconnect the tool hoses.

In some examples, as shown in <FIG>, the system <NUM> includes a hose management system <NUM>. The hose management system <NUM> includes a hose management tool <NUM> that contains the plurality of tool hoses <NUM>. More specifically, the hose management tool <NUM> organizes and houses the plurality of tool hoses <NUM>. The tool manifold <NUM> is coupled to an upper end <NUM> of the hose management tool <NUM>. The plurality of tool hoses <NUM> are connected to the hose end <NUM> of a corresponding one of the plurality of tool fittings <NUM> at the upper end <NUM> of the hose management tool <NUM>, allowing any connected flowable-material source <NUM> to deliver flowable material through the plurality of tool hoses <NUM> to the tool manifold <NUM>. In one example, the plurality of tool hoses <NUM> remain connected to the corresponding tool fittings <NUM> and the delivery of flowable material is controlled through the control system <NUM>. In other examples, the plurality of tool hoses <NUM> can be individually connected and disconnected to the corresponding tool fittings <NUM> as needed to control which tool fittings <NUM> are connected for delivery of flowable materials.

In <FIG>, according to some examples, a part-forming fixture <NUM> is shown. The part-forming fixture <NUM> can be any of various part-forming fixtures having any of various shapes and sizes. In one example, the part-forming fixture <NUM> is a mandrel that is used during a composite fuselage fabrication process. In some examples, the mandrel is divided into segments, such that only a segment or multiple segments of the mandrel are used during the fuselage fabrication process. In other examples, the part-forming fixture <NUM> could be a stiffener detail block fabrication tool, such as a male hat stringer or a 777x blade tool, a wing skin or empennage skin fabrication tool, or an IML empennage fabrication tool. The part-forming fixture <NUM> has a part-forming surface <NUM> and includes a plurality of ports <NUM>. Each port <NUM> is configured to deliver flowable-material to a portion of the part-forming surface <NUM> of the part-forming fixture <NUM>. The ports <NUM> may be capable of receiving multiple types of flowable-materials, such as hot air, pressurized air or depressurized air (e.g., a vacuum), or may be specialized for a specific type of flowable-material. The ports <NUM> may be located along an input end <NUM> of the part-forming fixture <NUM> and an output end <NUM> of the part-forming fixture <NUM>. Accordingly, in some examples, the flowable-material can enter a port <NUM> at the input end <NUM> of the part-forming fixture <NUM> and exit a port <NUM> at the output end <NUM> of the part-forming fixture <NUM>.

The fixture manifold <NUM> is coupled to the part-forming fixture <NUM>. In one example, the fixture manifold <NUM> is coupled at the part-forming surface <NUM> of the part-forming fixture <NUM> at the input end <NUM> of the part-forming fixture <NUM>. In other examples, the part-forming fixture <NUM> includes a tooling structure <NUM> fixed to the part-forming surface <NUM>, at the input end <NUM> of the part-forming fixture <NUM> and the fixture manifold <NUM> is fixed to the tooling structure <NUM>. For example, the tooling structure <NUM> can include a center panel <NUM> and the fixture manifold <NUM> can be fixed to the center panel <NUM>. The tooling structure can further include a plurality of arms <NUM> that extend from the center panel <NUM> and are fixed to the part-forming surface <NUM>. In some cases, the plurality of arms may be hollow and function to house the plurality of fixture hoses <NUM> that extend from the fixture manifold <NUM> to the corresponding port <NUM> on the part-forming fixture <NUM>.

Referring to <FIG> and <FIG>, the part-forming fixture <NUM> is in a work cell <NUM>, or an area where the part-forming fixture <NUM> is positioned during the part-forming process. The part-forming fixture <NUM> may be placed on a fixture frame <NUM>, which elevates the part-forming fixture <NUM> from the ground without interfering with the part-forming surface <NUM>. Generally, due to the size of the part-forming fixture <NUM>, the part-forming fixture <NUM>, although allowed to rotate, does not change its translational location while in the work cell <NUM>. Therefore, in some examples, the hose management tool <NUM> is configured to be movable away and towards the part-forming fixture <NUM>. In other words, the hose management tool <NUM> can be moved or stored away from the work cell <NUM> until it is needed, when it can be moved adjacent to the part-forming fixture <NUM> and the tool manifold <NUM> can be quickly connected to the fixture manifold <NUM>. In some examples, rotation of the part-forming fixture <NUM> is necessary for a user to access, or to more comfortably access, portions of the part-forming surface <NUM>. Accordingly, the part-forming fixture <NUM> can rotate, and the tool manifold <NUM> and fixture manifold <NUM>, when coupled together, co-rotate while the part-forming fixture <NUM> is rotated.

In one example, the part-forming fixture <NUM> is loaded on the fixture frame <NUM> in the work cell <NUM> in order to perform fixture preparation work, such as leak checks at each of the ports <NUM> on the part-forming fixture <NUM>. The hose management tool <NUM> is connected to the part-forming fixture <NUM> by interconnecting the tool manifold <NUM> to the fixture manifold <NUM>, as shown in <FIG>. Accordingly, the flowable-material source <NUM>, attached to the hose management tool <NUM>, is connected to the ports <NUM> on the part-forming fixture <NUM> via the connected tool hoses <NUM> and fixture hoses <NUM>. Tests for vacuum pressure, leak checks, vacuum decay checks, air flow, etc., can be performed on specific ports <NUM> on the part-forming fixture <NUM> with port-caps installed to ports <NUM> on the part-forming fixture <NUM> that are not being tested at that time. The part-forming fixture <NUM> can be rotated as needed to access the specific ports <NUM> for testing. By interconnecting the tool manifold <NUM> to the fixture manifold <NUM>, it is possible to test each port <NUM> on the part-forming fixture <NUM>, without the need to connect and disconnect hoses manually from the ports <NUM>. Additionally, the control system <NUM> can be operated to measure, monitor, report, and control the flow of flowable-material to individual tool hoses, etc., during any fixture preparation work.

In another example, the part-forming fixture <NUM> is in the work cell <NUM> in order to perform the part forming process. The materials for the part, or a section of the part, are manually applied to the part-forming surface <NUM>. Vacuum pressure is required for forming and compacting the materials, therefore a vacuum bag is applied over the vacuum-requiring part or section of the part, and a vacuum is applied to the ports <NUM> on the fixture that correlate with the part or section of the part. The control system <NUM> can be operated to monitor the vacuum level and duration of the vacuum. In some examples, sections of the part-forming fixture <NUM> can be maintained under vacuum while other work is performed on the part-forming fixture <NUM>. The control system <NUM> can be used to deliver vacuum to all of the fixture <NUM> at once or to sections of the part-forming fixture <NUM> as needed. The control system <NUM> can also be used to perform leak checks during the part-forming process. Additionally, the control system <NUM> can be used to maintain vacuum on seams if the fixture has segmented sections.

As shown in <FIG> and <FIG>, the system <NUM> can be used within an autoclave <NUM>, for example, the system <NUM> can be used in the autoclave <NUM> during a composite-material curing process. Prior to moving the part-forming fixture <NUM> within the autoclave <NUM>, the tool manifold <NUM>, if connected, is disconnected from the fixture manifold <NUM> and the hose management tool <NUM> is positioned away from the part-forming fixture <NUM> to prevent any damage or collision to the part-forming fixture <NUM> or hose management tool <NUM>. In some examples, the part-forming fixture <NUM> can be loaded onto an autoclave cart <NUM>, which does not interfere with the part-forming surface <NUM>, and moved into the autoclave <NUM>. The part-forming fixture <NUM> remains on the autoclave cart <NUM> during the autoclave process. In some examples, multiple fixtures <NUM> can be moved within the autoclave <NUM> during the same autoclave process, with each fixture <NUM> having an attached fixture manifold <NUM> and corresponding tool manifold <NUM>.

The hose management tool <NUM> is moved adjacent to the fixture manifold <NUM> within the autoclave <NUM> and the tool manifold <NUM> is coupled to the fixture manifold <NUM>. The fixture manifold <NUM> is connected to an input end <NUM> of the part-forming fixture <NUM>. In some examples, the hose management tool <NUM> is separate from the autoclave <NUM> and positioned within the autoclave <NUM> for the autoclave process. In other examples, the hose management tool <NUM> is connected within the autoclave <NUM>, such as being connected to an autoclave wall and having the tool manifold <NUM> pivotable towards and away from the fixture manifold <NUM>. In other words, the same hose management tool <NUM> can be used for both the work cell <NUM> and the autoclave <NUM>, or one hose management tool <NUM> can be used in the work cell <NUM> and another hose management tool <NUM> can be used within the autoclave <NUM>.

In some examples, an output tool <NUM> is positioned adjacent to an output end <NUM> of the part-forming fixture <NUM>, the output end <NUM> spaced apart from the input end <NUM> of the part-forming fixture <NUM>. The input end <NUM> and output end <NUM> each have ports <NUM> along the surface on the part-forming fixture <NUM>. The ports <NUM> on the input end <NUM> configured to receive a flowable material and the ports <NUM> on the output end <NUM> configured to allow the flowable material to exit the part-forming fixture <NUM>. A tool manifold <NUM> is coupled to the output tool <NUM> and is removably attachable to a fixture manifold <NUM> coupled to the output end <NUM> of the part-forming fixture <NUM>.

Generally, the part-forming fixture <NUM> does not require rotation while in the autoclave <NUM>. Accordingly, the tool manifold <NUM>, which is non-rotating in some examples as shown in <FIG>, can be coupled with the hose management tool <NUM> and connected to the fixture manifold <NUM> on the part-forming fixture <NUM>. In other examples, the rotating tool manifold <NUM>, as shown in <FIG>, can alternatively be coupled with the hose management tool <NUM> and connected to the fixture manifold <NUM> on the part-forming fixture <NUM>, however, the tool manifold <NUM> will not be rotated during the autoclave process.

Now referring to <FIG>, one example of a method <NUM> is shown. The method <NUM> includes (block <NUM>) positioning a hose management tool <NUM> including a plurality of tool hoses <NUM> and coupled with a tool manifold <NUM> adjacent to a fixture manifold <NUM> coupled to a fixture <NUM>. The tool manifold <NUM> including a plurality of tool fittings <NUM> and at least one of the plurality of tool hoses <NUM> removably attached to a corresponding one of the plurality of tool fittings <NUM>. The fixture manifold <NUM> includes a plurality of fixture fittings <NUM> and each one of a plurality of fixture hoses <NUM> connected to one of the plurality of fixture fittings <NUM> and to a corresponding one of a plurality of ports <NUM> on the part-forming fixture <NUM>. The method <NUM> also includes (block <NUM>) connecting the tool manifold <NUM> to the fixture manifold <NUM> via engagement of each one of the plurality of tool fitting <NUM> with a corresponding one of the plurality of fixture fittings <NUM> such that a seal is created between each tool fitting <NUM> and the corresponding fixture fitting <NUM>. The method <NUM> further includes (block <NUM>) supplying flowable material from at least one flowable-material source <NUM> to the at least one of the plurality of tool hoses <NUM> of the hose management tool <NUM>.

In some examples, the method <NUM> further includes clamping together the tool manifold <NUM> and the fixture manifold <NUM>, after connecting the tool manifold <NUM> and the fixture manifold <NUM>. A clamping mechanism <NUM> clamps together the tool manifold <NUM> with the fixture manifold <NUM>, so they do not separate while flowable material is being supplied to the part-forming fixture <NUM>.

The method <NUM> can be used to test the part-forming fixture <NUM> prior to forming a part on the part-forming fixture <NUM>. A vacuum test can performed on each port <NUM> of the plurality of ports <NUM> along at least a portion of the part-forming fixture <NUM>. In some examples, the vacuum test can be performed on every port <NUM> on the part-forming fixture <NUM>. After performing the vacuum test, materials can be applied to at least the portion of the part-forming fixture <NUM> where the ports <NUM> were tested. In some examples, the vacuum test can be performed on ports <NUM> during the part-forming process to ensure the ports are receiving or capable of receiving the necessary vacuum quality.

In some examples, the method <NUM> is performed on a fixture <NUM> that is in a work cell <NUM>. In other examples, the method <NUM> is performed on a fixture <NUM> that is in an autoclave <NUM>. For example, after applying materials to at least a portion of the part-forming fixture <NUM>, the part-forming fixture <NUM> is moved into an autoclave <NUM>. The hose management tool 156A is positioned adjacent to an input end <NUM> of the fixture and, in some cases, an output tool 156B is positioned adjacent to an output end of the part-forming fixture <NUM>. The tool manifold <NUM> is connected to the fixture manifold <NUM> at the input end <NUM> of the fixture and the output tool 156B is connected to the fixture manifold <NUM> coupled to the output end <NUM> of the part-forming fixture <NUM>. Hot air is supplied from the at least one flowable-material source <NUM> to heat the materials on at least a portion of the part-forming fixture <NUM>, the hot air flowing from the at least one flowable-material source <NUM>, through the part-forming fixture <NUM> and exiting from the output tool 156B.

In some examples, the flowable material supplied from the flowable-material source <NUM> is controlled by a control system <NUM> that is communicatively coupled with the flowable-material source <NUM>, such as in the methods shown in <FIG> and <FIG>.

Referring to <FIG>, one example of a method <NUM> is shown for the process of delivering flowable material to a part-forming fixture <NUM> using a control system <NUM> that is communicatively coupled with at least one flowable-material source <NUM>. The method <NUM> includes (block <NUM>) using the control system <NUM> to select at least one flowable-material source <NUM> to be delivered to a part-forming fixture <NUM>. The method <NUM> also includes (block <NUM>) using the control system <NUM> to select the tool hose(s) to deliver the at least one flowable-material source <NUM>. The method further includes (block <NUM>) determining whether to deliver the at least one flowable material. If a user and/or the control system <NUM> determines not to deliver the at least one flowable material <NUM> the process is ended (block <NUM>). Alternatively, if a user and/or the control system <NUM> determines to deliver the at least one flowable material <NUM>, the control system <NUM> sends a signal to the solenoid(s) <NUM> that corresponds to the selected tool hose(s) <NUM> (block <NUM>). The signal sent to the corresponding solenoid(s) <NUM> selectively turns on the solenoid(s) <NUM>, such that flowable material from the at least one flowable-material source <NUM> can flow to the plurality of tool fittings <NUM>. The method <NUM> also includes (block <NUM>) ending the delivery of the at least one flowable-material source <NUM> using the control system <NUM>. After the delivery is ended, the method <NUM> may further include (block <NUM>) displaying the results of the delivery of the at least one flowable-material source <NUM> to the part-forming fixture <NUM>. The results can be displayed on the control system <NUM> or a connected device, such as a computer communicatively connected to the control system <NUM>. Results may include but are not limited to the state of the solenoid(s) <NUM>, the state of the at least one flowable material <NUM>, and/or the state of the tool hose(s) <NUM>.

Now referring to <FIG>, one example of a method <NUM> is shown for the process of testing the system <NUM> for providing flowable material to a part-forming fixture <NUM>. The method <NUM> includes (block <NUM>) determining the type of test to be performed on the system <NUM>. In one example, the test may be a vacuum decay test of the flowable-material source <NUM>. In other examples, the type may be a test to determine and measure the flow rate of the at least one flowable-material source <NUM>. Other tests could also be performed on the system <NUM>. The method <NUM> also includes (block <NUM>) using the control system <NUM> to select the tool hose(s) <NUM> to be tested.

The method <NUM> further includes (block <NUM>) inputting test parameters using the control system <NUM> or devices communicatively connected to the control system <NUM>. Test parameters may include but are not limited to time duration of the test, minimum starting vacuum level, etc. The method <NUM> also includes (block <NUM>) using the control system <NUM> to select the tool hose(s) to deliver the at least one flowable-material source <NUM>, such as the depressurized air (e.g., vacuum). The method <NUM> further includes (block <NUM>) using the control system <NUM> to send a signal to the solenoid(s) <NUM> that correspond to the selected tool hose(s) <NUM>. The signal sent to the corresponding solenoid(s) <NUM> selectively turns on the solenoid(s) <NUM>, such that the vacuum or other flowable material can flow to or from the plurality of tool fittings <NUM>. The method <NUM> includes (block <NUM>) ending the test performed on the system <NUM> using the control system <NUM>. After the test is ended, the method <NUM> may further include (block <NUM>) displaying the results of the test. Results may include but are not limited to the vacuum decay rate at each selected tool hose <NUM>, the vacuum flow rate at each selected tool hose <NUM>, etc..

In the above description, certain terms may be used such as "up," "down," "upper," "lower," "horizontal," "vertical," "left," "right," "over," "under" and the like. These terms are used, where applicable, to provide some clarity of description when dealing with relative relationships. But, these terms are not intended to imply absolute relationships, positions, and/or orientations. For example, with respect to an object, an "upper" surface can become a "lower" surface simply by turning the object over. Nevertheless, it is still the same object. Further, the terms "including," "comprising," "having," and variations thereof mean "including but not limited to" unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. Further, the term "plurality" can be defined as "at least two.

Additionally, instances in this specification where one element is "coupled" to another element can include direct and indirect coupling. Direct coupling can be defined as one element coupled to and in some contact with another element. Indirect coupling can be defined as coupling between two elements not in direct contact with each other, but having one or more additional elements between the coupled elements. Further, as used herein, securing one element to another element can include direct securing and indirect securing. Additionally, as used herein, "adjacent" does not necessarily denote contact. For example, one element can be adjacent another element without being in contact with that element.

As used herein, the phrase "at least one of", when used with a list of items, means different combinations of one or more of the listed items may be used and only one of the items in the list may be needed. The item may be a particular object, thing, or category. In other words, "at least one of" means any combination of items or number of items may be used from the list, but not all of the items in the list may be required. For example, "at least one of item A, item B, and item C" may mean item A; item A and item B; item B; item A, item B, and item C; or item B and item C. In some cases, "at least one of item A, item B, and item C" may mean, for example, without limitation, two of item A, one of item B, and ten of item C; four of item B and seven of item C; or some other suitable combination.

Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more steps, or portions thereof, of the illustrated method. Additionally, the format and symbols employed are provided to explain the logical steps of the method and are understood not to limit the scope of the method. Although various arrow types and line types may be employed in the flow chart diagrams, they are understood not to limit the scope of the corresponding method.
