The present disclosure relates to a cartridge for aerosol delivery devices such as electronic cigarettes, and more particularly to methods for assembling a cartridge for aerosol delivery devices including an atomizer, and associated systems and apparatuses. The atomizer may be configured to heat an aerosol precursor composition, which may be made or derived from tobacco or otherwise incorporate tobacco, to form an inhalable substance for human consumption.
Many smoking devices have been proposed through the years as improvements upon, or alternatives to, smoking products that require combusting tobacco for use. Many of those devices purportedly have been designed to provide the sensations associated with cigarette, cigar, or pipe smoking, but without delivering considerable quantities of incomplete combustion and pyrolysis products that result from the burning of tobacco. To this end, there have been proposed numerous smoking products, flavor generators, and medicinal inhalers that utilize electrical energy to vaporize or heat a volatile material, or attempt to provide the sensations of cigarette, cigar, or pipe smoking without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices and heat generating sources set forth in the background art described in U.S. Pat. No. 8,881,737 to Collett et al., U.S. Pat. App. Pub. No. 2013/0255702 to Griffith Jr. et al., U.S. Pat. App. Pub. No. 2014/0000638 to Sebastian et al., U.S. Pat. App. Pub. No. 2014/0096781 to Sears et al., U.S. Pat. App. Pub. No. 2014/0096782 to Ampolini et al., and U.S. Pat. App. Pub. No. 2015/0059780 to Davis et al., which are incorporated herein by reference in their entireties.

These and other features, aspects, and advantages of the disclosure will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below.
Having thus described the disclosure in the foregoing general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure will now be described more fully hereinafter with reference to exemplary embodiments thereof. These exemplary embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a”, “an”, “the”, include plural variations unless the context clearly dictates otherwise.
The present disclosure provides descriptions of systems for assembling aerosol delivery devices. The aerosol delivery devices may use electrical energy to heat a material (preferably without combusting the material to any significant degree) to form an inhalable substance; such articles most preferably being sufficiently compact to be considered “hand-held” devices. An aerosol delivery device may provide some or all of the sensations (e.g., inhalation and exhalation rituals, types of tastes or flavors, organoleptic effects, physical feel, use rituals, visual cues such as those provided by visible aerosol, and the like) of smoking a cigarette, cigar, or pipe, without any substantial degree of combustion of any component of that article or device. The aerosol delivery device may not produce smoke in the sense of the aerosol resulting from by-products of combustion or pyrolysis of tobacco, but rather, that the article or device most preferably yields vapors (including vapors within aerosols that can be considered to be visible aerosols that might be considered to be described as smoke-like) resulting from volatilization or vaporization of certain components of the article or device, although in other embodiments the aerosol may not be visible. In highly preferred embodiments, aerosol delivery devices may incorporate tobacco and/or components derived from tobacco. As such, the aerosol delivery device can be characterized as an electronic smoking article such as an electronic cigarette or “e-cigarette.”
While the systems are generally described herein in terms of embodiments associated with aerosol delivery devices such as so-called “e-cigarettes,” it should be understood that the mechanisms, components, features, and methods may be embodied in many different forms and associated with a variety of articles. For example, the description provided herein may be employed in conjunction with embodiments of traditional smoking articles (e.g., cigarettes, cigars, pipes, etc.), heat-not-burn cigarettes, and related packaging for any of the products disclosed herein. Accordingly, it should be understood that the description of the mechanisms, components, features, and methods disclosed herein are discussed in terms of embodiments relating to aerosol delivery mechanisms by way of example only, and may be embodied and used in various other products and methods.
Aerosol delivery devices of the present disclosure also can be characterized as being vapor-producing articles or medicament delivery articles. Thus, such articles or devices can be adapted so as to provide one or more substances (e.g., flavors and/or pharmaceutical active ingredients) in an inhalable form or state. For example, inhalable substances can be substantially in the form of a vapor (i.e., a substance that is in the gas phase at a temperature lower than its critical point). Alternatively, inhalable substances can be in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). For purposes of simplicity, the term “aerosol” as used herein is meant to include vapors, gases and aerosols of a form or type suitable for human inhalation, whether or not visible, and whether or not of a form that might be considered to be smoke-like.
In use, aerosol delivery devices of the present disclosure may be subjected to many of the physical actions employed by an individual in using a traditional type of smoking article (e.g., a cigarette, cigar or pipe that is employed by lighting and inhaling tobacco). For example, the user of an aerosol delivery device of the present disclosure can hold that article much like a traditional type of smoking article, draw on one end of that article for inhalation of aerosol produced by that article, take puffs at selected intervals of time, etc.
Smoking articles of the present disclosure generally include a number of components provided within an outer shell or body. The overall design of the outer shell or body can vary, and the format or configuration of the outer body that can define the overall size and shape of the smoking article can vary. Typically, an elongated body resembling the shape of a cigarette or cigar can be a formed from a single, unitary shell; or the elongated body can be formed of two or more separable pieces. For example, a smoking article can comprise an elongated shell or body that can be substantially tubular in shape and, as such, resemble the shape of a conventional cigarette or cigar. However, various other shapes and configurations may be employed in other embodiments (e.g., rectangular or fob-shaped).
In one embodiment, all of the components of the smoking article are contained within one outer body or shell. Alternatively, a smoking article can comprise two or more shells that are joined and are separable. For example, a smoking article can possess at one end a control body comprising a shell containing one or more reusable components (e.g., a rechargeable battery and various electronics for controlling the operation of that article), and at the other end and removably attached thereto a shell containing a disposable portion (e.g., a disposable flavor-containing cartridge). More specific formats, configurations and arrangements of components within the single shell type of unit or within a multi-piece separable shell type of unit will be evident in light of the further disclosure provided herein. Additionally, various smoking article designs and component arrangements can be appreciated upon consideration of the commercially available electronic smoking articles.
Aerosol delivery devices of the present disclosure most preferably comprise some combination of a power source (i.e., an electrical power source), at least one control component (e.g., means for actuating, controlling, regulating and/or ceasing power for heat generation, such as by controlling electrical current flow from the power source to other components of the aerosol delivery device), a heater or heat generation component (e.g., an electrical resistance heating element or component commonly referred to as part of an “atomizer”), and an aerosol precursor composition (e.g., commonly a liquid capable of yielding an aerosol upon application of sufficient heat, such as ingredients commonly referred to as “smoke juice,” “e-liquid” and “e-juice”), and a mouthend region or tip for allowing draw upon the aerosol delivery device for aerosol inhalation (e.g., a defined air flow path through the article such that aerosol generated can be withdrawn therefrom upon draw).
Alignment of the components within the aerosol delivery device of the present disclosure can vary. In specific embodiments, the aerosol precursor composition can be located near an end of the aerosol delivery device which may be configured to be positioned proximal to the mouth of a user so as to maximize aerosol delivery to the user. Other configurations, however, are not excluded. Generally, the heating element can be positioned sufficiently near the aerosol precursor composition so that heat from the heating element can volatilize the aerosol precursor (as well as one or more flavorants, medicaments, or the like that may likewise be provided for delivery to a user) and form an aerosol for delivery to the user. When the heating element heats the aerosol precursor composition, an aerosol is formed, released, or generated in a physical form suitable for inhalation by a consumer. It should be noted that the foregoing terms are meant to be interchangeable such that reference to release, releasing, releases, or released includes form or generate, forming or generating, forms or generates, and formed or generated. Specifically, an inhalable substance is released in the form of a vapor or aerosol or mixture thereof, wherein such terms are also interchangeably used herein except where otherwise specified.
As noted above, the aerosol delivery device may incorporate a battery or other electrical power source (e.g., a capacitor) to provide current flow sufficient to provide various functionalities to the aerosol delivery device, such as powering of a heater, powering of control systems, powering of indicators, and the like. The power source can take on various embodiments. Preferably, the power source is able to deliver sufficient power to rapidly heat the heating element to provide for aerosol formation and power the aerosol delivery device through use for a desired duration of time. The power source preferably is sized to fit conveniently within the aerosol delivery device so that the aerosol delivery device can be easily handled. Additionally, a preferred power source is of a sufficiently light weight to not detract from a desirable smoking experience.
More specific formats, configurations and arrangements of components within the aerosol delivery device of the present disclosure will be evident in light of the further disclosure provided hereinafter. Additionally, the selection of various aerosol delivery device components can be appreciated upon consideration of the commercially available electronic aerosol delivery devices. Further, the arrangement of the components within the aerosol delivery device can also be appreciated upon consideration of the commercially available electronic aerosol delivery devices.
One example embodiment of an aerosol delivery device 100 is illustrated in
In specific embodiments, one or both of the cartridge 300 and the control body 200 may be referred to as being disposable or as being reusable. For example, the control body 200 may have a replaceable battery or a rechargeable battery and/or capacitor and thus may be combined with any type of recharging technology, including connection to a typical alternating current electrical outlet, connection to a car charger (i.e., cigarette lighter receptacle), and connection to a computer, such as through a universal serial bus (USB) cable. Further, in some embodiments the cartridge 300 may comprise a single-use cartridge, as disclosed in U.S. Pat. No. 8,910,639 to Chang et al., which is incorporated herein by reference in its entirety.
With respect to the flow sensor 210, representative current regulating components and other current controlling components including various microcontrollers, sensors, and switches for aerosol delivery devices are described in U.S. Pat.

No. 6,040,560 to Fleischhauer et al., U.S. Pat. No. 7,040,314 to Nguyen et al., and U.S. Pat. No. 8,205,622 to Pan, all of which are incorporated herein by reference in their entireties. Reference also is made to the control schemes described in U.S. App. Pub. No. 2014/0270727 to Ampolini et al., which is incorporated herein by reference in its entirety.
In one embodiment the indicator 218 may comprise one or more light emitting diodes. The indicator 218 can be in communication with the control component 212 through the connector circuit 220 and be illuminated, for example, during a user drawing on a cartridge coupled to the coupler 202, as detected by the flow sensor 210. The end cap 222 may be adapted to make visible the illumination provided thereunder by the indicator 218. Accordingly, the indicator 218 may be illuminated during use of the aerosol delivery device 100 to simulate the lit end of a smoking article. However, in other embodiments the indicator 218 can be provided in varying numbers and can take on different shapes and can even be an opening in the outer body (such as for release of sound when such indicators are present).

A variety of the materials disclosed by the foregoing documents may be incorporated into the present devices in various embodiments, and all of the foregoing disclosures are incorporated herein by reference in their entireties.
In some embodiments the first and second heating terminals 320a, 320b may be embedded in, or otherwise coupled to, the flow director 308. For example, the first and second heating terminals 320a, 320b may be insert molded in the flow director 308. Accordingly, the flow director 308 and the first and second heating terminals are collectively referred to herein as a flow director assembly 322. Additional description with respect to the first and second heating terminals 320a, 320b and the flow director 308 is provided in U.S. Pat. Pub. No. 2015/0335071 to Brinkley et al., which is incorporated herein by reference in its entirety.
The atomizer 310 may comprise a liquid transport element 324 and a heating element 326. The cartridge may additionally include a base shipping plug engaged with the base and/or a mouthpiece shipping plug engaged with the mouthpiece in order to protect the base and the mouthpiece and prevent entry of contaminants therein prior to use as disclosed, for example, in U.S. Pat. No. 9,220,302 to Depiano et al., which is incorporated herein by reference in its entirety.
The base 302 may be coupled to a first end of the outer body 314 and the mouthpiece 316 may be coupled to an opposing second end of the outer body to substantially or fully enclose other components of the cartridge 300 therein. For example, the control component terminal 304, the electronic control component 306, the flow director 308, the atomizer 310, and the reservoir substrate 312 may be substantially or entirely retained within the outer body 314. The label 318 may at least partially surround the outer body 314, and optionally the base 302, and include information such as a product identifier thereon. The base 302 may be configured to engage the coupler 202 of the control body 200 (see, e.g.,
The reservoir substrate 312 may be configured to hold an aerosol precursor composition. Representative types of aerosol precursor components and formulations are also set forth and characterized in U.S. Pat. No. 7,726,320 to Robinson et al. and 8,881,737 to Collett et al., and U.S. Pat. Pub. Nos. 2013/0008457 to Zheng et al.; 2013/0213417 to Chong et al.; 2015/0020823 to Lipowicz et al.; and 2015/0020830 to Koller, as well as WO 2014/182736 to Bowen et al, the disclosures of which are incorporated herein by reference. Other aerosol precursors that may be employed include the aerosol precursors that have been incorporated in the VUSE® product by R. J. Reynolds Vapor Company, the BLU product by Lorillard Technologies, the MISTIC MENTHOL product by Mistic Ecigs, and the VYPE product by CN Creative Ltd. Also desirable are the so-called “smoke juices” for electronic cigarettes that have been available from Johnson Creek Enterprises LLC. Embodiments of effervescent materials can be used with the aerosol precursor, and are described, by way of example, in U.S. Pat. App. Pub. No. 2012/0055494 to Hunt et al., which is incorporated herein by reference. Further, the use of effervescent materials is described, for example, in U.S. Pat. No. 4,639,368 to Niazi et al.; U.S. Pat. No. 5,178,878 to Wehling et al.; U.S. Pat. No. 5,223,264 to Wehling et al.; U.S. Pat. No. 6,974,590 to Pather et al.; U.S. Pat. No. 7,381,667 to Bergquist et al.; U.S. Pat. No. 8,424,541 to Crawford et al; and U.S. Pat. No. 8,627,828 to Strickland et al.; as well as US Pat. Pub. Nos. 2010/0018539 to Brinkley et al. and 2010/0170522 to Sun et al.; and PCT WO 97/06786 to Johnson et al., all of which are incorporated by reference herein.
The reservoir substrate 312 may comprise a plurality of layers of nonwoven fibers formed into the shape of a tube encircling the interior of the outer body 314 of the cartridge 300. Thus, liquid components, for example, can be sorptively retained by the reservoir substrate 312. The reservoir substrate 312 is in fluid connection with the liquid transport element 324. Thus, the liquid transport element 324 may be configured to transport liquid from the reservoir substrate 312 to the heating element 326 via capillary action or other liquid transport mechanisms.
As illustrated, the liquid transport element 324 may be in direct contact with the heating element 326. As further illustrated in
However, various other embodiments of methods may be employed to form the heating element 326, and various other embodiments of heating elements may be employed in the atomizer 310. For example, a stamped heating element may be employed in the atomizer, as described in U.S. Pat. App. Pub. No. 2014/0270729 to DePiano et al., which is incorporated herein by reference in its entirety. Further to the above, additional representative heating elements and materials for use therein are described in U.S. Pat. No. 5,060,671 to Counts et al.; U.S. Pat. No. 5,093,894 to Deevi et al.; U.S. Pat. No. 5,224,498 to Deevi et al.; U.S. Pat. No. 5,228,460 to Sprinkel Jr., et al.; U.S. Pat. No. 5,322,075 to Deevi et al.; U.S. Pat. No. 5,353,813 to Deevi et al.; U.S. Pat. No. 5,468,936 to Deevi et al.; U.S. Pat. No. 5,498,850 to Das; U.S. Pat. No. 5,659,656 to Das; U.S. Pat. No. 5,498,855 to Deevi et al.; U.S. Pat. No. 5,530,225 to Hajaligol; U.S. Pat. No. 5,665,262 to Hajaligol; U.S. Pat. No. 5,573,692 to Das et al.; and U.S. Pat. No. 5,591,368 to Fleischhauer et al., the disclosures of which are incorporated herein by reference in their entireties. Further, chemical heating may be employed in other embodiments. Various additional examples of heaters and materials employed to form heaters are described in U.S. Pat. No. 8,881,737 to Collett et al., which is incorporated herein by reference, as noted above.
A variety of heater components may be used in the present aerosol delivery device. In various embodiments, one or more microheaters or like solid state heaters may be used. Microheaters and atomizers incorporating microheaters suitable for use in the presently disclosed devices are described in U.S. Pat. No. 8,881,737 to Collett et al., which is incorporated herein by reference in its entirety.
The first heating terminal 320a and the second heating terminal 320b (e.g., negative and positive heating terminals) are configured to engage opposing ends of the heating element 326 and to form an electrical connection with the control body 200 (see, e.g.,
During use, a user may draw on the mouthpiece 316 of the cartridge 300 of the aerosol delivery device 100 (see,
A sensor in the aerosol delivery device 100 (e.g., the flow sensor 210 in the control body 200) may sense the puff. When the puff is sensed, the control body 200 may direct current to the heating element 326 through a circuit including the first heating terminal 320a and the second heating terminal 320b. Accordingly, the heating element 326 may vaporize the aerosol precursor composition directed to an aerosolization zone from the reservoir substrate 312 by the liquid transport element 324. Thus, the mouthpiece 326 may allow passage of air and entrained vapor (i.e., the components of the aerosol precursor composition in an inhalable form) from the cartridge 300 to a consumer drawing thereon.
Various other details with respect to the components that may be included in the cartridge 300 are provided, for example, in U.S. Pat. App. Pub. No. 2014/0261495 to DePiano et al., which is incorporated herein by reference in its entirety. In this regard,
Various components of an aerosol delivery device according to the present disclosure can be chosen from components described in the art and commercially available. Reference is made for example to the reservoir and heater system for controllable delivery of multiple aerosolizable materials in an electronic smoking article disclosed in U.S. Pat. App. Pub. No. 2014/0000638 to Sebastian et al., which is incorporated herein by reference in its entirety.
In another embodiment substantially the entirety of the cartridge may be formed from one or more carbon materials, which may provide advantages in terms of biodegradability and absence of wires. In this regard, the heating element may comprise carbon foam, the reservoir substrate may comprise carbonized fabric, and graphite may be employed to form an electrical connection with the power source and control component. An example embodiment of a carbon-based cartridge is provided in U.S. Pat. App. Pub. No. 2013/0255702 to Griffith et al., which is incorporated herein by reference in its entirety.
As described above, cartridges of aerosol delivery devices may include a number of components. Some of the components may be relatively small and/or relatively delicate. Accordingly, precise manufacturing techniques may be required to form the aerosol delivery devices. In this regard, aerosol delivery devices have traditionally been formed via manual assembly by humans.
However, use of manual labor to assemble aerosol delivery devices suffers from certain detriments. In this regard, the quality of aerosol delivery devices produced via manual labor is only as good as the workers performing the labor. Further, even skilled workers may make errors from time-to-time. Additionally, manual labor may be relatively costly. Thus, as result of these issues and other issues associated with the production of aerosol delivery devices via manual labor, it may be desirable to produce aerosol delivery devices in an automated manner. Accordingly, automated production of cartridges for aerosol delivery devices is discussed hereinafter, which may provide enhanced repeatability, lower costs, and/or avoid other issues noted above.
In this regard,
As illustrated, the system 400 may include various subsystems that perform particular functions in the formation of the completed cartridges 300. Note that although the subsystems are illustrated as being separate from one another, the subsystems may overlap. For example, in some embodiments common equipment may perform two or more functions (e.g., assembly and filling or capping and labeling, etc.), rather than the particular functions being performed by separate equipment.
Further, the various subsystems and portions thereof may be separately usable. In this regard, although the subsystems and portions thereof are generally described herein as being usable together, this is by way of example. Accordingly, any of the subsystems or portions thereof described herein may be usable by themselves or in any combination with some or all of the other subsystems and portions thereof described herein, or used in combination with other systems. Example embodiments of other automated systems for assembling cartridges for aerosol delivery devices which may be employed in conjunction with the systems disclosed herein are disclosed in U.S. Pat. Pub. No. 2015/0223522 to Ampolini et al. and U.S. patent application Ser. No. 14/716,112 to Guenther et al., filed May 19, 2015, which are incorporated herein by reference in their entireties. Further, although particular embodiments of portions of the subsystems are disclosed hereinafter, these embodiments are provided for example purposes only. Accordingly, in some embodiments the subsystems may include fewer or additional portions. Thus, each portion of each subsystem, and each portion of the overall system is not required in all embodiments.
As illustrated, the subsystems may include a cartridge assembly subsystem 402 configured to form unfilled cartridges 404 from components 406 (e.g., the base 302, the first and second heating terminals 320a, 320b (see, e.g.,
The system 400 may additionally include an inspection subsystem 418. The inspection subsystem 418 may inspect the components 406, the unfilled cartridges 404, the filled cartridges 410, the capped cartridges 414, and/or the completed cartridges 300. Further, in some embodiments the cartridges may be inspected at intermediate states of completion at one or more of the cartridge assembly subsystem 402, the cartridge filling subsystem 408, the cartridge capping subsystem 412, and the cartridge labeling subsystem 416. Accordingly, the cartridges 300 and components thereof may be inspected before, during, and after completion thereof.
The system 400 may further include at least one controller 417. The controller 417 may be configured to control the cartridge assembly subsystem 402, the cartridge filling subsystem 408, the cartridge capping subsystem 412, and/or the cartridge labeling subsystem 416. In this regard, the controller 417 may be configured to receive data from one or more the sensors and output instructions based thereon, in addition to otherwise directing the operations described herein. Note that although a single controller is illustrated, in other embodiments the controller may include a plurality of controllers that control fewer than all of the functions and subsystems of the system, and which may or may not communicate with one another.
Note that some or all of the system 400 may be automated. In this regard, as described hereinafter, robotic apparatuses may be employed in some embodiments of the system 400. The robotic apparatuses may be provided from various robotic manufacturers including, by way of example, DENSO Robotics of Long Beach, CA, FANUC of Rochester Hills, MI, Mitsubishi Electric Automation of Vernon Hills, IL, EPSON Robots of Carson, CA, Siemens Automation Technology of Munich, Germany, Mikron Corporation of Denver, CO, and ATC Automation of Cookeville, TN.
A more detailed illustration of an example embodiment of the system 400 of
As illustrated in
Preferably, the system 400 may be configured to rapidly produce the cartridges 300 with minimal human interaction being required. In this regard, the assembly cells 502a-i may be collectively configured to assemble a plurality of cartridge components together and/or perform additional functions with respect to the cartridges 300. The system 400 may include certain features configured to improve the interaction between the assembly cells 502.
For example, the system 400 may include one or more assembly tracks 504a-e (collectively, “assembly tracks 504”). In the illustrated embodiment, a first assembly cell 502a includes an assembly track 504a, second and third assembly cells 502b, 502c share an assembly track 504b, fourth and fifth assembly cells 502d, 502e share an assembly track 504c, a sixth assembly cell 502f includes an assembly track 504d, and a seventh assembly cell 502h includes an assembly track 504e.
The assembly tracks 504 may be configured to circulate assembly carriages 506a-e (collectively, “assembly carriages 506”) thereon. The circulating assembly carriages 506 may be configured to engage a plurality of assemblies comprising one or more cartridge components 300-326. The assemblies are also referred to as partially-assembled cartridges 300. Thereby, the cartridges 300 may be assembled by combining the cartridge components 300-326 generally in an additive manner.
As noted above, the assembly tracks 504 may circulate the assembly carriages 506. Thereby, the assembly carriages 506 may be reused in the formation of a plurality of the cartridges 300 by returning to an initial starting point on the assembly tracks 504 following the removal of one or more partially or fully assembled cartridges 300 therefrom. Accordingly, cartridge assembly operations may be iteratively repeated for additional cartridge components directed thereto after the offloading of the one or more partially or fully assembled cartridges 300 assembled thereon.
In some embodiments each of the assembly carriages 506 may be configured to receive cartridge components for a single cartridge 300. Thereby, each of the assembly carriages 506 may be employed to assemble components for an individual cartridge 300 during each cycle. However, in other embodiments the assembly carriages 506 may be configured to receive cartridge components for a plurality of cartridges 300. Thereby, each of the assembly carriages 506 may be employed to assemble a plurality of cartridges 300. In this regard, by engaging, transporting, and assembling a plurality of the partially-assembled cartridges 300 on one of the assembly carriages 506, the rate at which the cartridges are assembled may be increased.
In order to perform each of the assembly operations associated with producing the cartridges 300, the partially-assembled cartridges may be transported to each of the assembly cells 502. Accordingly, one option is to assemble each cartridge on a single assembly carriage, which may be transported amongst each of the assembly cells. However, the assembly operations performed by each of the assembly cells 502 and the cartridge components employed in the assembly operations may vary considerably. Accordingly, Applicants have determined that assembly of the cartridges 300 may beneficially occur with usage of a plurality of differing assembly carriages in the system 400. Accordingly, each track 504 may include one or more assembly carriages 506 associated therewith, and the assembly carriages associated with one track may differ from the assembly carriages associated with one or more of the other assembly tracks.
Accordingly, the system 400 may further comprise one or more transfer apparatuses 508a-d (collectively, “transfer apparatuses 508”). The transfer apparatuses 508 may be configured to transfer the partially-assembled cartridges 300 between a pair of the assembly cells 502. Thereby, the partially-assembled cartridges 300 may be transferred from the assembly carriage 506 at a first one of the cells 502 to a second one of the cells.
In order to transfer the partially-assembled cartridges 300, the transfer assemblies 508 may each include a transfer track 510a-d (collectively, “transfer tracks 510”). In some embodiments the partially-assembled cartridges 300 may be transported directly on the transfer track 510. In another embodiment the transfer assemblies 508 may respectively include one or more transfer carriages 512a-d (collectively, “transfer carriages 512”) configured to engage partially-assembled cartridges 300, and the transfer carriages may transport the partially-assembled cartridges via movement of the transfer track 510. The transfer carriages 512 may circulate on the respective transfer tracks 508. Thereby, the transfer carriages 512 may be reused to transfer the partially-assembled cartridges 300 between the assembly cells 502.
Each transfer apparatus 508 may further comprise a first transfer member 514a-d (collectively, “first transfer members 514”) configured to disengage the partially-assembled cartridges 300 from the assembly carriages 512 on an assembly track 504 of a first one of the pair of the assembly cells 502 and engage the partially-assembled cartridges with a respective one of the transfer carriages 512 on the transfer track 510. Further, each transfer apparatus 508 may comprise a second transfer member 516a-d (collectively, “second transfer members 516”) configured to disengage the partially-assembled cartridges 300 from the transfer carriages 512 and engage the partially-assembled cartridges with one of the assembly carriages 506 of a second one of the pair of the assembly cells 502. The first and second transfer members 514, 516 may each comprise a robotic arm in some embodiments.
In one embodiment the transfer carriages 512 may be configured to engage and simultaneously transfer each of the partially-assembled cartridges 300 held by one of the assembly carriages 506. However, in another embodiment the transfer carriages 512 may be configured to engage a single one of the partially-assembled cartridges 300 at a time. Thereby, the transfer apparatuses 508 may individually and sequentially transfer the partially-assembled cartridges 300 between the pair of the assembly cells 504.
By sequentially transporting the partially-assembled cartridges 300, certain benefits may be provided. In this regard, the partially-assembled cartridges 300 may be inspected by the inspection subsystem 418 (see,
Thus, if the transfer carriages 512 were to be configured to hold the same number of partially-assembled carriages 300 as the assembly carriage 506 upstream thereof, the transfer carriages would in some instances include fewer partially-assembled cartridges than a capacity thereof. Accordingly, the transfer carriages 512 may be configured to hold fewer partially-assembled cartridges 300 than the assembly carriages 506 from which the partially-assembled cartridges are received. For example, as noted above, in one embodiment the transfer carriages 512 may be configured to engage a single one of the partially-assembled cartridges 300 at a time. Thereby, the second transfer member 516 may transfer the partially-assembled cartridges 300 to assembly carriages 506 at the downstream assembly cell 502. As a result of the partially-assembled cartridges 300 being transferred individually, the second transfer member 516 may continue engaging the partially-assembled carriages directed thereto until the assembly carriage 506 at the downstream assembly cell 502 is full, such that each assembly carriage is full.
By employing the transfer assemblies 508 to singulate the partially-assembled cartridges 300 in this manner, issues with respect to assembly carriages 506 transporting fewer partially-assembled cartridges than a capacity thereof may be avoided. In this regard, as noted above, the second transfer members 516 may engage partially-assembled cartridges with the assembly carriages 506 at the downstream assembly cell 502 until the capacity thereof is reached. In contrast, if the partially-assembled cartridges 300 were to be transported to each of the assembly cells on the same carriage throughout the assembly process, the removal of partially-assembled cartridges for inspection or quality control purposes would result in the carriages transporting fewer partially-assembled cartridges than the capacity thereof. Accordingly, usage of separate assembly tracks 504 and transfer tracks 510 may be desirable for this additional reason.
In some embodiments each assembly cell 502 may include a respective assembly track 504. In another embodiment some of the assembly cells 502 may share an assembly track. For example, in the embodiment illustrated in
Operation of the system 400 is described hereinafter. As may be understood, the operations described herein may be performed in various other orders and in various other manners. Further, it should be understood that the assembly operations performed will vary depending on the particular embodiment of the cartridge undergoing production. Although the system 400 is described herein as producing the cartridges 300 of
At the first assembly cell 502a, the assembly carriage 506a on the assembly track 504a may receive a plurality of the bases 302. A vision system rotates the bases 302 to a desired orientation that may be maintained through some or all of the cartridge assembly process. The control component terminals 304 are engaged with the bases 302. The electronic control components 306 are engaged with the control component terminals 304. The electronic control components 306 may be programed through the control component terminals 304. The flow director assemblies 322 are engaged with the bases 302. The flow director assemblies 322 are welded or otherwise affixed to the bases 302 (e.g., via ultrasonic welding).
Defective partially-assembled cartridges 300 may be identified (e.g., by the inspection subsystem 418; see,
After welding, an electrical resistance between the first and second heating terminals 320a, 320b (see,
At the fourth assembly cell 502d, the assembly carriage 506c on the assembly track 504c may receive the partially-assembled cartridges 300 from the transfer assembly 508b. The partially-assembled cartridges 300 received from the third assembly cell 502c may comprise the base 302, the control component terminal 304, the electronic control component 306, the flow director assembly 322, and the atomizer 310. The liquid transport element 324 of the atomizer 310 may be folded against the first and second heating terminals 320a, 320b of the flow director assembly 322 (see,
At the fifth assembly cell 502e, the reservoir substrates 312 may be cut from a substantially-continuous input and engaged with an assembly carriage 506c. The assembly track 504c may deliver the assembly carriage 506c to the fourth assembly cell 502d, at which the partially-assembled cartridges 300, with the liquid transport elements 324 folded against the flow director assemblies 322, may be engaged with the reservoir substrates 312 such that the reservoir substrates are at least partially wrapped around the flow director assemblies. Outer bodies 314 may then be engaged with the partially-assembled cartridges 300 by extending over the reservoir substrates 312 and into engagement with the flow director assemblies 322. The presence and position of the control component terminals 304 and the first and second heating terminals 320a, 320b (see,
At the fifth assembly cell 502e, the inspection subsystem 418 (see,
Samples of the partially-assembled cartridges 300 may also be removed for further quality control inspections. The remaining partially-assembled cartridges 300 may be unloaded from the assembly carriage 506c and transported by the transfer assembly 508c to the sixth assembly cell 502f. The assembly carriage 506c at the third assembly track 504c may be returned to an initial starting point for production of additional cartridges 300.
At the sixth assembly cell 502f, the assembly carriage 506f on the assembly track 504d may receive the partially-assembled cartridges 300 from the transfer assembly 508c. The partially-assembled cartridges 300 received from the fifth assembly cell 502e may comprise the base 302, the control component terminal 304, the electronic control component 306, the flow director assembly 322, the atomizer 310, the reservoir substrate 312, and the outer body 314. The sixth assembly cell 502f may fill the partially-assembled cartridges with an aerosol precursor composition 328. The partially-assembled cartridges 300 may be weighed before and after filling by the inspection subsystem 418 (see,
At the seventh assembly cell 502g, the assembly carriage 506e on the assembly track 504e may receive the partially-assembled cartridges 300 from the transfer assembly 508d. The partially-assembled cartridges 300 received from the third assembly cell 502c may comprise the base 302, the control component terminal 304, the electronic control component 306, the flow director assembly 322, the atomizer 310, the reservoir substrate 312, the outer body 314, and the aerosol precursor composition 328. The mouthpieces 316 may be engaged with the outer bodies 314 and affixed (e.g., ultrasonically welded) thereto at the seventh assembly cell 502g. In some embodiments the outer bodies 314 may be marked (e.g., laser marked) with a date code or other identifier at the seventh assembly cell 502g. Further, the identifiers may be inspected by the inspection subsystem 418 (see,
At the eight assembly cell 502h, the partially-assembled cartridges 300 received from the seventh assembly cell 502g may comprise the base 302, the control component terminal 304, the electronic control component 306, the flow director assembly 322, the atomizer 310, the reservoir substrate 312, the outer body 314, the aerosol precursor composition 328, and the mouthpiece 316. The label 318 may be applied to the outer bodies 314 to complete the cartridges at the eighth assembly cell 502h. Further, the completed cartridges 300 may be directed to the ninth assembly cell 502i, at which packaging 330 may be applied to the cartridges 300, such that the cartridges are ready for retail sale.
As noted above, the assembly cells 502 may include assembly carriages 506 that are particularly configured for the components received therein and assembly operations performed therewith. For example,
Further,
In this regard, the first nest 606 may comprise a receptacle 610 configured to receive the base 302 (see, e.g.,
The first nest 606 may be configured to receive the partially-assembled cartridge 300 and retain the partially-assembled cartridge in the recess 610. In this regard, the first nest 610 may include a locking member 614, which may clamp the partially-assembled cartridge 300 in the recess 610 such that the partially-assembled cartridge does not fall over or out of the first nest. For example, the locking member 614 may be configured to apply force to the base 302 (see, e.g.,
Further, the second nest 608 may comprise one or more clamps 616 configured to receive and hold the atomizer 310 (see, e.g.,
Accordingly, once the atomizer 310 (see, e.g.,

Further, as illustrated in
In this regard, the first nest 624 may comprise a recess 628 configured to receive the partially-assembled cartridge 300. The recess 628 of the first nest 624 may be configured to hold the partially-assembled cartridge 300 in a substantially horizontal configuration. Conversely, the second nest 626 may comprise a receptacle 630 configured to receive a base 302 (see, e.g.,
As further illustrated in
As illustrated in
Accordingly, the partially-assembled cartridge 300 may be prepared for insertion into the first nest 624 of the assembly carriage 506c. In this regard, the liquid transport element 324 of the atomizer 310 may be folded against the first and second heating terminals 320a, 320b of the flow director assembly 322 (see,
In particular, as illustrated in
Thereby, the flow director gripper 636 may direct the partially-assembled cartridge 300 generally from right to left in terms of the illustrated orientation such that the base 302 (see, e.g.,
Once the atomizer 310 is received between the folding pins 640, the base gripper 644 may grip the base 302 of the partially-assembled cartridge 300. The flow director gripper 636 may then release the flow director 308 and return to a starting position. The folding pins 640 may then move inwardly toward the partially-assembled cartridge 300 such that the atomizer 310 folds into contact with the flow director 308.
A transport gripper 646 may then grasp the partially-assembled cartridge 300 by pinching the atomizer 310 against the flow director 308 such that the atomizer retains the folded configuration formed at the folding apparatus 638. The folding pins 640 and the base gripper 644 may release the partially-assembled cartridge 300. The transport gripper 646 may then transport the partially-assembled cartridge 300 to, and deposit the partially-assembled cartridge in, the assembly carriage 506c.
Thereby, as illustrated in
As illustrated in
In order to clamp the reservoir substrate 312 against the partially-assembled cartridge 300 in this manner, the first nest 624 may further define first and second openings 650a, 650b positioned at the first and second opposing sides 624a, 624b of the first nest 624. Accordingly, the first and second prongs 648a, 648b of the end effector 648 may extend through the first and second openings 650a, 650b in the nest 624 to clamp the reservoir substrate 312 against the partially-assembled cartridge 300. After the outer body 314 (see, e.g.,
In some embodiments of the method, individually and sequentially transporting the partially-assembled cartridges on the transfer track at operation 704 may include respectively engaging each of the partially-assembled cartridges with one of one or more transfer carriages. Individually and sequentially transporting the partially-assembled cartridges on the transfer track at operation 704 may further comprise disengaging the partially-assembled cartridges from the assembly carriages of a first one of the pair of the assembly cells and engaging the partially-assembled cartridges with a respective one of the transfer carriages. Additionally, individually and sequentially transporting the partially-assembled cartridges on the transfer track at operation 704 may include disengaging the partially-assembled cartridges from the transfer carriages and engaging the partially-assembled cartridges with one of the assembly carriages of a second one of the pair of the assembly cells.
In some embodiments receiving the partially-assembled cartridge in the first orientation in the first nest of the assembly carriage at operation 802 may include receiving a base of the partially-assembled cartridge such that the partially-assembled cartridge defines a substantially vertical configuration. Further, the method may include receiving and holding an atomizer in a substantially horizontal configuration at the second nest. Receiving the partially-assembled configured cartridge in the second orientation in the second nest of the assembly carriage at operation 804 may include receiving the partially-assembled cartridge in a recess configured to hold the partially-assembled cartridge in a substantially horizontal configuration. Receiving the partially-assembled cartridge in the recess may include holding the partially-assembled cartridge such that a first heating terminal and a second heating terminal thereof are in contact with a heating element of the atomizer. Receiving and holding the atomizer in the substantially horizontal configuration at the second nest may include clamping the atomizer on first and second opposing sides of the partially-assembled cartridge.
In another embodiment the method may further include engaging a reservoir substrate with a clamp at the first nest. Receiving the partially-assembled cartridge in the first orientation in the first nest at operation 802 may include inserting the partially-assembled cartridge into a recess, the recess being aligned and recessed with respect to the clamp such that the reservoir substrate wraps at least partially around the partially-assembled cartridge during insertion of the partially-assembled cartridge into the recess. Engaging the reservoir substrate with the clamp may include engaging the reservoir substrate with a plurality of prongs that extend on first and second opposing sides of the nest. Further, the method may include directing an end effector into first and second openings positioned at the first and second opposing sides of the nest and clamping the reservoir substrate against the partially-assembled cartridge with the end effector. Engaging the prongs with the reservoir substrate may include pressing the reservoir substrate against the first and second opposing sides of the nest, the first and second opposing sides of the nest being elevated with respect to the recess.
As may be understood, the particular subsystems included in the system 400 (see,
The subsystems 402′, 408′, 412′, 416′, 420′ may respectively include one or more assembly cells 502a-g′ (collectively, “assembly cells 502′”). In the embodiment illustrated in
Preferably, the system 400′ may be configured to rapidly produce the cartridges 300 with minimal human interaction being required. In this regard, the assembly cells 502′ may be collectively configured to assemble a plurality of cartridge components together and/or perform additional functions with respect to the cartridges 300. In this regard, each assembly cell 502′ may include an intra-cell transporter configured to transport the partially-assembled cartridges therethrough as various operations are performed thereon. Thereby, the partially or fully assembled cartridges 300 may be transported by the intra-cell transporter at each of the assembly cells 502′ as the components of the cartridges are assembled together or other operations are performed thereon.
By way of example, the first assembly cell 502a′ may include a rotary table 504a′, which may receive the base 302. In one embodiment the rotary table 504a′ may comprise a NR1100 rotary indexing ring available from Weiss GMBH of Buchen, Germany. Further, in some embodiments the bases 302 may be transported to rotary table 504a′ via a linear feed system available from Vibratory Tooling & Repair, Inc. of Ontario, Canada.
The rotary table 504a′ may transport the base 302 to various positions within the first assembly cell 502a′ at which additional components may be engaged therewith. In particular, the control component terminal 304 may be engaged with the base 302, the electronic control component 306 may be engaged with the control component terminal, and the flow director assembly 322 may be engaged with the base. Further, the flow director assembly 322 may be affixed to the base (e.g., ultrasonically welded thereto) at the first assembly cell 502a′.
However, issues with respect to component movement may occur during the welding process. In this regard, as illustrated in
Thereby, contact between the welding receptacle 500 and the base 302 and between the welding receptacle and the terminals 320a, 320b, 304 may stabilize each of the components of the partially-assembled cartridge 300 as well as the electronic control component 306, which is engaged with the control component terminal. In order to contact the base 302 and the terminals 320a, 320b, 304, in some embodiments a portion of the body 501 of the welding fixture 500 may define a size and shape substantially corresponding to that of the coupler 202 of the control body 200 (see,
Accordingly, the rotary table 504a′ may position the base 302 for the engagement of other components therewith and performance of operations thereon at the first assembly cell 502a′. However, various other embodiments of intra-cell transporters may be employed at the assembly cells 502′. For example, as schematically illustrated in
As noted above, the electronic control component 306 may be engaged with the control component terminal 304 at the first assembly cell 502a′. However, issues with respect to static electricity buildup on the electronic control components 306 may affect the assembly of the cartridge 300 and/or programming thereof. In this regard, static buildup on the electronic control components 306 may cause the electronic control components to attract and bind with one another, which may make it more difficult to singulate the electronic control components prior to engagement with a respective control component terminal 304. Additionally or alternatively, static electricity built up on the electronic control components 306 may discharge during or after assembly, which may clear the memory thereon or present other issues with respect to storing information on the electronic control components.
Accordingly, as illustrated in
As illustrated in
By way of example,
In some embodiments the inter-cell transporter 512a′ may be configured to transport the partially-assembled cartridges 300 in side profile. In other words, the inter-cell transporter may transport the partially-assembled cartridges 300 such that the partially-assembled cartridges 300 are moved in a direction perpendicular to a longitudinal axis thereof. Thus, the transport lines 516a′ may define a cross-sectional profile corresponding to a side profile of the partially-assembled cartridge 300 leaving the first assembly cell 502a′. However, in other embodiments the partially-assembled cartridges 300 may be transported through the transport lines 516a′ in a direction parallel to the longitudinal axis thereof.
Regardless of the particular embodiment of the inter-cell transporter 512a′ employed, the partially-assembled cartridges 300 may be transported to the second assembly cell 502b′. As illustrated in
An example embodiment of the second assembly cell 502b′ is illustrated in
In this regard, as illustrated in
The dispensing clamp 528′ may be configured to grasp the substantially-continuous input 518′ at a starting position. Once grasped, the dispensing clamp 528′ may pull on the substantially-continuous input 518′, by moving generally from left to right in terms of the illustrated orientation to an extended position. Thereby, the end clamp 530′ may grasp the substantially-continuous input 518′ proximate an end thereof. The dispensing clamp 528′ may then release the substantially-continuous input 528′, move back to the starting position (e.g., by moving generally right to left in terms of the illustrated orientation), and grasp the substantially-continuous input, as illustrated in
As illustrated, the substantially-continuous input 518′ may comprise a plurality of heating elements 326 engaged with the substantially-continuous liquid transport element 324. In this regard, the dispensing clamp 528′ and the end clamp 530′ may be configured to clamp the substantially-continuous input 518′ such that the segment 520a′ includes one of the heating elements 326. Accordingly, the segment 520a′ of the substantially-continuous input 518′ may be positioned for engagement with one of the partially-assembled cartridge assemblies 300.
In this regard, the assembly feeder 522′ may be configured to engage the first heating terminal 320a and the second heating terminal 320b of one of the partially-assembled cartridges 300 with one of the heating elements 326 at the segment 520a′ of the substantially-continuous input 518′. For example, as described above, the partially-assembled cartridge 300 may further comprise a base 302 and a flow director 308, wherein the first heating terminal 320a and the second heating terminal 320b extend through the flow director. Thereby, the assembly feeder 522′ may grasp the partially-assembled cartridges 300 such that the first heating terminal 320a and the second heating terminal 320b are exposed for engagement with the heating element 326 at the segment 520a′ of the substantially-continuous input 518′. As illustrated, the assembly feeder 522′ may include at least one end effector 532′ configured to engage the base 302 of the partially-assembled cartridge 300. In some embodiments the end effector 532′ may be configured to apply a negative pressure to the base 302 of the partially-assembled cartridge 300 to retain the partially-assembled cartridge in engagement therewith during movement of the assembly feeder 522′.
Further, as illustrated in
Once the first heating terminal 320a and the second heating terminal 320b of the partially-assembled cartridge 300 engage the heating element 326 at the segment 520a′ of the substantially-continuous input 518′, the welder 524′ (see,
As further illustrated in
In this regard, the laser welder 536′ may include an adjustable optical lens 542′ configured to focus the laser beam 538′ within the space 540′. Thereby, the welder 524′ may focus the laser beam 538′ at the first heating terminal 320a and the second heating terminal 320a of the partially-assembled cartridge 300 or corresponding portions of the heating element 326 (see, e.g.,
Accordingly, the first heating terminal 320a and the second heating terminal 320b may be welded to the heating element 326 in the configuration illustrated in
Note that cutting the substantially-continuous input 518′ after welding the heating element 326 to the first and second heating terminals 320a, 320b may provide benefits as compared to singulating the atomizer 310 (see, e.g.,
Further, by cutting the substantially-continuous input 518′ after welding the atomizer 310 to the first and second heating terminals 320a, 320b, the input feeder 504b′ may firmly grasp the substantially-continuous input 518′ during welding. In this regard, in embodiments in which the atomizer 310 is singulated before welding, the length of the liquid transport element 324 defines the boundaries at which the atomizer may be grasped. In contrast, when the segment 520a′ is still intact with the substantially-continuous input 518′, the substantially-continuous input may be grasped at any point therealong.
For example, as illustrated in
Accordingly, the partially-assembled cartridge 300 may include an atomizer 310 (see,
As illustrated in
Thus, the second input feeder 504b″ may be substantially the same as, and include the same components as, the input feeder 504b′. Additionally, the second input feeder 504b″ may be substantially the same as, and include the same components as, the input feeder 504b′. Accordingly, the input feeders 504b′, 504b″ and the assembly feeders 522′, 522″ may position the partially-assembled cartridges 300 in contact with the substantially-continuous inputs 518′, 518″. Thereby, the first and second heating terminals 320a, 320b of the partially-assembled cartridges 300 may be welded to the heating elements 326 at both of the substantially-continuous inputs 518′, 518″.
As noted above in relation to
Accordingly, in some embodiments a single welding apparatus (e.g., the welder 524′) may be employed to weld two assembly lines of the partially-assembled cartridges 300 directed through the second assembly cell 502b′. Similarly, in some embodiments a single cutter (e.g., the cutter 526′) may be employed to cut both of the substantially-continuous inputs 518′, 518″. In this regard, in some embodiments the first assembly feeder 522′ and the first input feeder 504b′ may be out of synch with the second assembly feeder 522″ and the second input feeder 504b″ such that the welder 524′ and/or the cutter 526′ may alternatingly perform operations on the first substantially-continuous input 518′ and the second substantially-continuous input 518″. Usage of a single welder and/or a single cutter may reduce costs and complexity of the second assembly cell 502b′. However, as may be understood, in other embodiments, multiple welders and/or cutters may be employed at the second assembly cell.
Note that although the heating element 326 is described herein as being attached to the heating terminals 320a, 320b via laser welding, various other types of welding may be employed, such as arc welding, metal inert gas welding (MIG), tungsten inert gas welding (TIG), plasma welding, etc. More broadly, the heating elements may be affixed to the heating terminals via other methods, such as soldering and mechanical connections. Accordingly, it should be understood that various other embodiments of coupling methods and related equipment may be employed without departing from the scope of the present disclosure.
Accordingly, as illustrated in
As noted above with respect to
As illustrated in
Thus, in one example embodiment, each assembly gripper 546′ may include a plurality of clamps 548A-C′ (generically and collectively, “clamp(s) 548′”). Each clamp 548′ may include a first finger 550′ and a second finger 552′. As illustrated in
Each assembly gripper 546′ may further include a body 554′ to which the clamps 548′ are hingedly coupled. The body 554′ may be integral or comprise multiple pieces, which may be positioned between the clamps 548′. The body 554′ may define at least one access port 556′. The access port 556′ may be configured to receive an actuator pin 558′ (see, e.g.,
In this regard,
Each assembly gripper 546′ may include multiple clamps 548′. For example, in the embodiment illustrated in
As illustrated in
Once the actuator pin 558′ is fully inserted, the clamps 548′ may be spread apart in the open configuration, as illustrated in
Thus, as illustrated in
As illustrated in
As illustrated in
Thus, as illustrated in
In this regard, when the actuator pin 558′ is retracted out through the access port 556′ in the body 554′ (see, e.g.,
Thus, the liquid transport element 324 may be securely clamped against the sides of the flow director, 308. The springs 572′, 574′ may be in compression in both the open configuration illustrated in
Positioning the liquid transport element 324 in a folded configuration along the sides of the flow director 308 may allow the reservoir substrate 312 (see, e.g.,
Accordingly, the assembly gripper 546′ may be prepared for receipt of the reservoir substrate 312 (see, e.g.,
After the clamps 548′ are opened, the partially-assembled cartridge assembly 300 may be stabilized. In this regard, as illustrated in
Accordingly, as illustrated in
In order to engage the reservoir substrate 312, the substrate gripper 580′ may include one or more protrusions 582′. For example, the protrusions 582′ may include an inner protrusion 584′ and outer protrusion 586′. At least one of the protrusions 582′ may be configured to apply a negative pressure to the reservoir substrate 312. In this regard, at least one of the protrusions 582′ may include a pressure port 588′ configured to apply the negative pressure to the reservoir substrate 312 to retain the reservoir substrate in engagement therewith. By way of example, the inner protrusion 584′ includes the pressure port 588′ in the illustrated embodiment. In this regard, as described below, the inner protrusion 584′ may remain substantially stationary with respect to the reservoir substrate 312 by remaining in engagement therewith during wrapping of the reservoir substrate about the partially-assembled cartridge 300, whereas the outer protrusions 586′ may move with respect to the reservoir substrate during wrapping of the substrate about the partially-assembled cartridge 300.
Accordingly, as illustrated in
As illustrated in
Accordingly, as illustrated in
After the reservoir substrate 312 is added to the partially-assembled cartridge 300, the outer body 314 may be engaged therewith. In this regard,
As illustrated in
This method of operation may still allow the clamps 548′ to clamp the reservoir substrate 312 during the outer body 314 engagement process. In this regard, when the upper clamp 548A′ is fully open and the outer body 314 is directed at least partially over the partially-assembled cartridge 300, the middle clamp 548B′ and the lower clamp 548C′ may be at least partially closed and in engagement with the reservoir substrate 312 to assist in retaining the reservoir substrate in a desired position. Accordingly, the sequential opening of the clamps 548 while the outer body 314 is directed over the partially-assembled cartridge 300 may assist in coupling the outer body to the partially-assembled cartridge without moving the reservoir substrate 312 from a desired position. In this regard, if the reservoir substrate 312 were to shift out of position, it may extend between the outer body 314 and the base 302, which may provide an undesirable appearance and/or potentially cause fluid leakage from the assembled cartridge.
After the outer body 314 is added to the partially-assembled cartridge 300, the outer body may be welded thereto. For example, the outer body 314 may be attached to the flow director 308 and/or the base 302. By way of further example, the outer body 314 may be ultrasonically welded to the flow director 308 and/or the base 302. However, as may be understood, the outer body 314 may be affixed to the remainder of the partially-assembled cartridge 300 in various other manners in other embodiments.
In this regard, as illustrated in
In particular as illustrated in
As noted above, the first fingers 550′ and the second fingers 552′ of the assembly gripper 546′ may release from the partially-assembled cartridge 300 during the welding operation so as to not interfere therewith. In this regard, it may be desirable to provide the outer body 314 with a degree of freedom to move with respect to the base 302 to allow the ultrasonic vibrations to produce a sufficient degree of heat to melt one or both of the outer body 314 and the base 302 at the interface therebetween and form a weld. However, too much freedom of movement of the outer body 314 with respect to the base 302 may allow misalignment therebetween.
Whereas the base 302 may be firmly grasped between the base protrusions 660a′, 660b′, the intermeshing protrusions 658a′, 658b′ and the outer body protrusions 662a′, 662b′ may loosely grasp the outer body 314. In this regard, a distance between the outer body protrusion 662a′ of the first cartridge gripper 656a′ and the outer body protrusion 662b′ of the second cartridge gripper 656b′ may be greater than a distance between the base protrusion 660a′ of the first cartridge gripper and the base protrusion 660b′ of the second cartridge gripper. Further, a distance between the outer body protrusion 662a′ of the first cartridge gripper 656a′ and the outer body protrusion 662b′ of the second cartridge gripper 656b′ is greater than a dimension of the outer body 314 of the cartridge 300 therebetween (e.g. the diameter thereof) when the base protrusion 660a′ of the first cartridge gripper and the base protrusion 660b′ of the second cartridge gripper engage the base 302 of the cartridge. Accordingly, the outer body 314 may be gripped more loosely than the base 302. For example, the outer body protrusions 662a′, 662b′ may be positioned adjacent to, but out of contact with, the outer body 314. Further, whereas each of the base protrusions 660a′, 660b′ and the intermeshing protrusions 658a′ and the outer body protrusion 662a′ of the first cartridge gripper 656a′ may respectively define a groove 660a1′, 660b1′, 658a1′, 662a1′ configured to receive the cartridge therein, intermeshing protrusions 658b′ and the outer body protrusion 662b′ of the second cartridge gripper 656b′ may respectively define a substantially flat face 658b1′, 662b1′.
Thereby, by providing a greater separation between the outer body protrusions 662a′, 662b′ than the base protrusions 660a′, 660b′ and/or providing some of the protrusions with the flat face 658b1′, 662b1′, the outer body 314 may move slightly between the first and second cartridge grippers 656a′, 656b′ to allow for constrained relative movement of the outer body 314 with respect to the base 302 when an ultrasonic horn 664 is lowered into engagement with the top of the outer body. By allowing for movement, a weld may be produced at the interface between the outer body 314 and the base 302. In this regard, gripping the outer body 314 too tightly may otherwise result in the top of the outer body 314 mushrooming outwardly due to movement with respect to the ultrasonic horn 664′. This mushrooming effect may be avoided by allowing the outer body 314 to move relative to the base 302. However, the first and second cartridge grippers 656a′, 656b′ may constrain the movement such that the outer body 314 and the base 302 maintain proper alignment during the welding process.
Note that although the description provided above generally describes tightly clamping the base and allowing constrained movement of the outer body during ultrasonic welding, in other embodiments the opposite configuration may be employed. In other words, the outer body may be tightly clamped, whereas the base may be allowed to move within a constrained space dictated by the welding clamp. In this embodiment the ultrasonic horn may engage the base at an end thereof opposite from the outer body. Accordingly, as may be understood, the welding clamp may be configured in various manners to tightly clamp one of two components being ultrasonically welded together, and allow for constrained movement of the second component which is contacted by the ultrasonic horn to weld the two components together in a desired alignment. This configuration may be used in any ultrasonic welding method and is thus applicable to welding components other than a base and an outer body.
After the outer body 314 is welded to the partially-assembled cartridge 300, the partially-assembled cartridge may be offloaded from the rotary track 504c′ and transported via the third inter-cell transporter 512c′ to the fourth assembly cell 502d′ at which the partially-assembled cartridge 300 may be filled with the aerosol precursor composition 328, as illustrated in
The partially-assembled cartridge 300 may include the flow director 308 which is surrounded by the reservoir substrate 312 (see, e.g.,
Accordingly, the partially-assembled cartridge 300 may be filled at a relatively slower rate or the aerosol precursor composition 328 (see,
In this regard, as illustrated in
The manifold 678′ may be positioned at a location at the cartridge filling subsystem 408′ at which the partially-assembled cartridges 300 (see, e.g.,
Note that the system 400 of
However, in some embodiments the cartridge filling subsystem 408 may be configured to fill the partially-assembled cartridges 300 (see, e.g.,
Returning to the system 400′ of
The partially-assembled cartridge 300 may then be directed via the fifth inter-cell transporter 512e′ to the sixth assembly cell 502f at which the labels 318 may be attached to complete the cartridge. In some embodiments the label 318 may be heat shrunk onto the partially-assembled cartridge 300 in order to provide a smooth and integral appearance. Following attachment of the label 318, the completed cartridges 300 may be directed via the sixth-inter-cell transporter 512f to the seventh assembly cell 502g′ at which the cartridge 300 may be packaged.
As noted above, the inspection subsystem 418 may be configured to inspect the cartridges 300 in various states of completion in each of the systems 400, 400′. As illustrated in
As illustrated in
A first electrical contact 428A may be configured to engage the first heating terminal 320a (see, e.g.,
However, engagement of the cartridge 300 (see, e.g.,
The compliant member 432 may provide compliance in any number of manners. For example, the compliant member may include springs that allow for movement thereof. In another embodiment the compliant member 432 may comprise a resilient material (e.g., rubber) that allows for movement of the receptacle 426 when the cartridge 300 (see, e.g.,
As may be understood, various other configurations of test fixtures may be employed to test or otherwise perform operations on cartridges. For example,
The test fixture 422′ may further comprise components configured to provide the receptacle 426′ with compliance in order to improve connectivity with the cartridge 300 (see, e.g.,
For example, as illustrated in
Further, each of the electrical contacts 428A′-C′ may be configured to move along a second horizontal axis 438′, which may be perpendicular to the first horizontal axis 436′, to allow for movement in any direction within a horizontal plane perpendicular to an axis 434′ of insertion of the cartridge 300 into the receptacle 426′. For example, the test fixture 422′ may include a rail 440′ upon which a slide bearing 442′ is configured to slide. The receptacle 426′ may be engaged with the slide bearing 442′ to allow for movement thereof along the second horizontal axis 438′ as noted above. Further, springs or other devices may be configured to return the receptacle 426 to a central position aligned with the axis 434′ of insertion to facilitate engagement with each cartridge 300. Accordingly, the test fixtures of the present disclosure may be configured in various manners to provide a degree of compliance that may improve connectivity with the partially or fully assembled cartridges such that testing and other functions may occur even when the cartridges are not inserted perfectly into the center of the test fixture.
In an additional embodiment an aerosol delivery device assembly method is provided. As illustrated in
In some embodiments welding the first heating terminal and the second heating terminal to the one of the heating elements at operation 908 may comprise laser welding the first heating terminal and the second heating terminal to the one of the heating elements with a laser welder by focusing a laser at the first heating terminal and the second heating terminal. The laser welder, the first heating terminal, and the second heating terminal may remain stationary during and between welding the first heating terminal and the second heating terminal to the one of the heating elements. In this regard, as described above with respect to
In some embodiments providing the first heating terminal and the second heating terminal at operation 904 may comprise providing an assembly comprising a base and a flow director, wherein the first heating terminal and the second heating terminal extend through the flow director. Further, engaging the first heating terminal and the second heating terminal with the one of the heating elements at operation 906 may comprise rotating a rotary transporter.
In some embodiments positioning the reservoir substrate in contact with the assembly at operation 1006 may include engaging the substrate with a substrate gripper comprising one or more protrusions configured to apply a negative pressure thereto. Further, closing the clamps at operation 1008 may include receiving the one or more protrusions in one or more gaps positioned between the clamps. The method may additionally include retracting the substrate gripper after closing the clamps by retracting the one or more protrusions through the one or more gaps.
The method may further comprise engaging a cap with the assembly while positioning the reservoir substrate in contact with the assembly at operation 1006.
