The present disclosure relates to a cartridge for aerosol delivery devices such as smoking articles, and more particularly to methods for assembling a cartridge for smoking articles including an atomizer. The atomizer may be configured to heat an aerosol precursor, which may be made or derived from tobacco or otherwise incorporate tobacco, to form an inhalable substance for human consumption.
Cigarettes, cigars and pipes are popular smoking articles that employ tobacco in various forms. For example, a traditional type of cigarette has a substantially cylindrical rod-shaped structure and includes a charge, roll or column of smokable material, such as shredded tobacco (e.g., in cut filler form), surrounded by a paper wrapper, thereby forming a so-called “smokable rod”, “tobacco rod” or “cigarette rod.” Normally, such a cigarette has a cylindrical filter element aligned in an end-to-end relationship with the tobacco rod. Preferably, a filter element comprises plasticized cellulose acetate tow circumscribed by a paper material known as “plug wrap.” Preferably, the filter element is attached to one end of the tobacco rod using a circumscribing wrapping material known as “tipping paper.” It also has become desirable to perforate the tipping material and plug wrap, in order to provide dilution of drawn mainstream smoke with ambient air. Descriptions of cigarettes and the various components thereof are set forth in Tobacco Production, Chemistry and Technology, Davis et al. (Eds.) (1999); which is incorporated herein by reference in its entirety. A traditional type of cigarette is employed by a smoker by lighting one end of the tobacco rod. The smoker then receives mainstream smoke into his/her mouth by drawing on the opposite end (e.g., the filter end or mouth end) of the burning cigarette.
Through the years, efforts have been made to improve upon the components, construction and performance of smoking articles that require combustion of tobacco for smoke generation. Many of the improvements that have been proposed purportedly attempt 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 burning tobacco. See, for example, the various references described, discussed, or referenced in U.S. Pat. No. 7,753,056 to Borschke et al.; which is incorporated herein by reference in its entirety.
Certain types of cigarettes that employ carbonaceous fuel elements have been commercially marketed under the brand names “Premier” and “Eclipse” by R. J. Reynolds Tobacco Company. See, for example, those types of cigarettes described in Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R. J. Reynolds Tobacco Company Monograph (1988) and Inhalation Toxicology, 12:5, p. 1-58 (2000). Additionally, a similar type of cigarette recently has been marketed in Japan by Japan Tobacco Inc. under the brand name “Steam Hot One.” Furthermore, various types of smoking products incorporating carbonaceous fuel elements for heat generation and aerosol formation recently have been set forth in the patent literature. See, for example, the types of smoking products proposed in U.S. Pat. No. 7,836,897 to Borschke et al.; U.S. Pat. No. 8,469,035 to Banerjee et al. and U.S. Pat. No. 8,464,726 to Sebastian et al.; US Pat. Pub. Nos. 2012/0042885 to Stone et al.; 2013/0019888 to Tsuruizumi et al; 2013/0133675 to Shinozaki et al. and 2013/0146075 to Poget et al.; PCT WO Nos. 2012/0164077 to Gladden et al.; 2013/098380 to Raether et al.; 2013/098405 to Zuber et al.; 2013/098410 to Zuber et al. and 2013/104914 to Woodcock; EP 1808087 to Baba et al. and EP 2550879 to Tsuruizumi et al.; which are incorporated herein by reference in their entirety.
In recent years, there have been proposed numerous smoking products, flavor generators and medicinal inhalers that utilize electrical energy to heat and vaporize volatile materials, or otherwise attempt to provide many of the sensations of smoking, without burning tobacco to any significant degree. See, for example, the various types of aerosol generation devices described, discussed, or referenced in U.S. Pat. No. 7,726,320 to Robinson et al., U.S. patent application Ser. No. 13/826,929, filed Mar. 14, 2013, to Ampolini et al., Ser. No. 14/011,992, filed Aug. 28, 2013, to Davis et al., and Ser. No. 14/170,838, filed Feb. 3, 2014, to Bless 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. The invention includes any combination of two, three, four, or more of the above-noted embodiments as well as combinations of any two, three, four, or more features or elements set forth in this disclosure, regardless of whether such features or elements are expressly combined in a specific embodiment description herein. This disclosure is intended to be read holistically such that any separable features or elements of the disclosed invention, in any of its various aspects and embodiments, should be viewed as intended to be combinable unless the context clearly dictates otherwise.
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.
As described hereinafter, embodiments of the present disclosure relate to aerosol delivery devices and methods and equipment for assembly thereof. Aerosol delivery devices according to the present disclosure 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 may yield 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. In highly preferred embodiments, aerosol delivery devices may incorporate tobacco and/or components derived from tobacco.
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.
Aerosol delivery devices of the present disclosure generally include a number of components provided within an outer body or shell. The overall design of the outer body or shell can vary, and the format or configuration of the outer body that can define the overall size and shape of the aerosol delivery device 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, an aerosol delivery device 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. In one embodiment, all of the components of the aerosol delivery device are contained within one outer body or shell. Alternatively, an aerosol delivery device can comprise two or more shells that are joined and are separable. For example, an aerosol delivery device can possess at one end a control body comprising an outer body or 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 an outer body or 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 aerosol delivery device designs and component arrangements can be appreciated upon consideration of the commercially available electronic aerosol delivery devices, such as those representative products listed above in the present disclosure. For example, an embodiment of an aerosol delivery device comprising multiple outer bodies and a coupler is described in U.S. patent application Ser. No. 14/170,838, filed Feb. 3, 2014, to Bless et al., which is incorporated herein by reference in its entirety, as noted above.
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 ceasing power for heat generation, such as by controlling electrical current flow from the power source to other components of the article), a heater or heat generation component (e.g., an electrical resistance heating element or component commonly referred to as 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 can vary. In specific embodiments, the aerosol precursor composition can be located near an end of the article (e.g., within a cartridge, which in certain circumstances can be replaceable and disposable), 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. Additionally, the selection of various aerosol delivery device components can be appreciated upon consideration of the commercially available electronic aerosol delivery devices, such as those representative products listed above in the present disclosure.
An aerosol delivery device incorporates a battery or other electrical power source to provide current flow sufficient to provide various functionalities to the article, 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 article through use for the 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; and additionally, a preferred power source is of a sufficiently light weight to not detract from a desirable smoking experience.
One example embodiment of an aerosol delivery device 100 is illustrated in
In specific embodiments, one or both of the cartridge 200 and the control body 300 may be referred to as being disposable or as being reusable. For example, the control body 300 may have a replaceable battery or a rechargeable battery 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 200 may comprise a single-use cartridge, as disclosed in U.S. patent application Ser. No. 13/603,612, filed Sep. 5, 2012, which is incorporated herein by reference in its entirety.
With respect to the flow sensor 310, 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. 4,735,217 to Gerth et al., U.S. Pat. Nos. 4,922,901, 4,947,874, and 4,947,875, all to Brooks et al., U.S. Pat. No. 5,372,148 to McCafferty et al., 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. application Ser. No. 13/837,542 to Ampolini et al., filed Mar. 15, 2013, which is incorporated herein by reference in its entirety.
In one embodiment the indicator 318 may comprise one or more light emitting diodes. The indicator 318 can be in communication with the control component 312 through the connector circuit 320 and illuminate, for example, during a user drawing on a cartridge coupled to the coupler 302, as detected by the flow sensor 310. The end cap 322 may be adapted to make visible the illumination provided thereunder by the indicator 318. Accordingly, the indicator 318 may illuminate during use of the aerosol delivery device 100 to simulate the lit end of a smoking article. However, in other embodiments the indicator 318 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).

The aerosol precursor composition, also referred to as a vapor precursor composition, may comprise a variety of components including, by way of example, a polyhydric alcohol (e.g., glycerin, propylene glycol, or a mixture thereof), nicotine, tobacco, tobacco extract, and/or flavorants. Various components that may be included in the aerosol precursor composition are described in U.S. Pat. No. 7,726,320 to Robinson et al., which is incorporated herein by reference in its entirety. Additional representative types of aerosol precursor compositions are set forth in U.S. Pat. No. 4,793,365 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,101,839 to Jakob et al.; PCT WO 98/57556 to Biggs et al.; and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R. J. Reynolds Tobacco Company Monograph (1988); the disclosures of which are incorporated herein by reference in their entireties. Other aerosol precursors which may be employed in the aerosol delivery device of the present disclosure include the aerosol precursors included 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. Additional exemplary formulations for aerosol precursor materials that may be used according to the present disclosure are described in U.S. Pat. Pub. No. 2013/0008457 to Zheng et al., the disclosure of which is incorporated herein by reference in its entirety.
The reservoir substrate 214 may comprise a plurality of layers of nonwoven fibers formed into the shape of a tube encircling the interior of the outer body 216 of the cartridge 200. Thus, liquid components, for example, can be sorptively retained by the reservoir substrate 214. The reservoir substrate 214 is in fluid connection with the liquid transport element 238. Thus, the liquid transport element 238 may be configured to transport liquid from the reservoir substrate 214 to the heating element 240 via capillary action.
As illustrated, the liquid transport element 238 may be in direct contact with the heating element 240. As further illustrated in
However, various other embodiments of methods may be employed to form the heating element 240, and various other embodiments of heating elements may be employed in the atomizer 212. For example, a stamped heating element may be employed in the atomizer, as described in U.S. patent application Ser. No. 13/842,125, filed Mar. 15, 2013, 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. patent application Ser. No. 13/602,871, filed Sep. 4, 2012, 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. Embodiments of microheaters that may be utilized are further described herein. Further microheaters and atomizers incorporating microheaters suitable for use in the presently disclosed devices are described in U.S. patent application Ser. No. 13/602,871, filed Sep. 4, 2012, which is incorporated herein by reference in its entirety.
The first heating terminal 234a and the second heating terminal 234b (e.g., positive and negative terminals) at the opposing ends of the heating element 240 are configured to form an electrical connection with the control body 300 when the cartridge 200 is connected thereto. Further, when the control body 300 is coupled to the cartridge 200, the electronic control component 208 may form an electrical connection with the control body through the control component terminal 206. The control body 300 may thus employ the electronic control component 208 to determine whether the cartridge 200 is genuine and/or perform other functions. Further, various examples of electronic control components and functions performed thereby are described in U.S. patent application Ser. No. 13/647,000, filed Oct. 8, 2012, which is incorporated herein by reference in its entirety.
During use, a user may draw on the mouthpiece 220 of the cartridge 200 of the aerosol delivery device 100. This may pull air through an opening in the control body 300 or in the cartridge. For example, in one embodiment an opening may be defined between the coupler 302 and the outer body 304 of the control body 300, as described in U.S. patent application Ser. No. 13/841,233; Filed Mar. 15, 2013, which is incorporated herein by reference in its entirety. However, the flow of air may be received through other parts of the aerosol delivery device 100 in other embodiments. As noted above, in some embodiments the cartridge 200 may include the flow tube 210. The flow tube 210 may be configured to direct the flow of air received from the control body 300 to the heating element 240 of the atomizer 212.
A sensor in the aerosol delivery device 100 (e.g., a puff or flow sensor in the control body 300) may sense the puff. When the puff is sensed, the control body 300 may direct current to the heating element 240 through a circuit including the first heating terminal 234a and the second heating terminal 234b. Accordingly, the heating element 240 may vaporize the aerosol precursor composition directed to an aerosolization zone from the reservoir substrate 214 by the liquid transport element 238. Thus, the mouthpiece 220 may allow passage of air and entrained vapor (i.e., the components of the aerosol precursor composition in an inhalable form) from the cartridge 200 to a consumer drawing thereon.
Various other details with respect to the components that may be included in the cartridge 200, are provided, for example, in U.S. patent application Ser. No. 13/840,264, filed Mar. 15, 2013, 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.
Note further that portions of the cartridge 200 illustrated in
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 may comprise carbonized fabric, and graphite may be employed to form an electrical connection with the battery and controller. 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. 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. Accordingly, 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 200. 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 are 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. Thus, for example, although an example embodiment of a cartridge filling subsystem is described hereinafter as being employed to fill cartridges filled by embodiments of cartridge assembly subsystems disclosed herein, the cartridge filling subsystem may be employed to fill cartridges formed by other subsystems and/or the cartridges assembled by the cartridge assembly subsystems may be filled by other cartridge filling subsystems. 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 204, the heating terminals 234a, 234b, etc.). A cartridge filling subsystem 408 may fill the unfilled cartridges 404 to produce filled cartridges 410. A cartridge capping subsystem 412 may cap the filled cartridges 410 to produce capped cartridges 414. A cartridge labeling subsystem 416 may apply labels to the capped cartridges 414 to complete the completed cartridges 200.
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 200. 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 200 and components thereof may be inspected before, during, and after completion thereof.
The system my further 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 may be configured to receive data from one or more of the sensors described herein and output instructions based thereon, in addition to otherwise directing the operations described herein.
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, Calif., FANUC of Rochester Hills, Mich., Mitsubishi Electric Automation of Vernon Hills, Ill., and Siemens Automation Technology of Munich, Germany.
An example embodiment of the cartridge assembly subsystem 402 is illustrated in
By way of example, the cartridge assembly subsystem 402 may include a base load substation 502, a terminal coupling substation 504, a terminal sealing substation 506, a control component coupling substation 508, a flow tube coupling substation 510, a heating element coupling substation 512, a liquid transport element bending substation 514, a reservoir coupling substation 516, and an outer body coupling substation 518. As illustrated, the controller 417 may be configured to control one or more of the substations 502-518 of the cartridge assembly subsystem 402. Briefly, the base load substation 502 may be configured to receive a base (e.g., the base 204) and orient the base for assembly with the various other components of the cartridge. The terminal coupling substation 504 may be configured to couple one or more terminals (e.g., the first and second heating terminals 234a,b and the control component terminal 206) to the base. The terminal sealing substation 506 may be configured to seal one or more of the terminals with respect to the base to prevent fluid ingress or egress between the base and the terminal(s). The control component coupling substation 508 may be configured to couple a control component (e.g., the electronic control component 208) to the control component terminal. The flow tube coupling substation 510 may be configured to couple a flow tube (e.g., the flow tube 210) to the control component, the first and second heating terminals, and/or other components. The heating element coupling substation 512 may be configured to couple a heating element (e.g., the heating element 240) to the heating terminals. The liquid transport element bending station 514 may be configured to bend a liquid transport element (e.g., the liquid transport element 238) about the heating terminals. The reservoir coupling substation 516 may be configured to couple a reservoir substrate (e.g., the reservoir substrate 214) to the liquid transport element. Further, the outer body coupling substation 518 may be configured to couple an outer body (e.g., the outer body 216) to the base.
The cartridge assembly subsystem 402 may assemble the cartridge (e.g., the cartridge 200) in a variety of manners. For example, in one embodiment the cartridge may be assembled generally upwardly from a base. In other words, components may be inserted into or otherwise coupled to the base to build up the cartridge therefrom.
In this regard, as illustrated in
Various embodiments of biasing mechanisms may be employed, such as magnets, hydraulic or pneumatic cylinders, etc. However, in the illustrated embodiment a rod 610 may be received in a mount 612. The mount 612, which may also function to align the piston 604 with respect to the groove 608, may include a spring therein that biases the rod 610 toward the head 606 of the piston. Accordingly, the head 606 of the piston 604 may be biased toward the groove 608 to retain the base 204 therein. Further, the piston 604 may include a handle 614 at an end thereof opposite from the head 606. The handle 614 may be configured to allow for grasping thereof, via automated or manual methods, to oppose the force provided by the biasing mechanism to thereby release the base 204.
The transport system may further comprise a rail 616 or other mechanism configured to provide for movement of the carriages between a plurality of substations. The carriages 600 may be mounted to the rail 616 using wheels 618 (see, e.g.,
It may be desirable to stop or slow down movement of the carriages 600 at one or more of the substations while one or more operations are conducted in order to simplify coupling parts of the cartridge to the base. Further, in some embodiments it may be desirable to lock the carriages 600 in a predefined position to substantially prevent movement of the carriages at one or more of the substations. In this regard, magnetic locking of a position of the carriage may be insufficient to properly lock a carriage in place because magnetic locking may still allow for some movement of the carriage. Accordingly, a locking apparatus may be employed to temporarily restrain movement of each carriage 600 along the rail 616.
The locking apparatus may include a locator mechanism 624 coupled to each carriage 600. In the illustrated embodiment, the locator mechanism 624 comprises first and second pegs 626. Further, the locking apparatus may comprise an engagement mechanism 628, which may be positioned at each location at which locking the carriage 600 in place is desired. Thus, the engagement mechanism 628 may be located at a fixed position relative to the longitudinal length of the rail 616. However, the engagement mechanism 628 may be configured to move into contact with the locator mechanism 624 (e.g., via a pneumatic piston, hydraulic piston, or linear motor) to lock the carriage 600 in place.
In the illustrated embodiment, the engagement mechanism 628 comprises a cylinder 630. Accordingly, as the engagement mechanism 628 is directed upwardly, the cylinder 630 may contact one or both of the pegs 626 of the locator mechanism 624. Thereby, the pegs 626 may deflect from the cylinder 630 such that the locator mechanism 624 becomes centered with respect to the engagement mechanism 628. Further, in one embodiment the cylinder 630 may comprise a roller or wheel configured to rotate to facilitate centering between the pegs 626 by allowing the cylinder to rotate when brought into contact with one of the pegs, rather than scraping thereagainst. Regardless of whether or not the cylinder 630 rotates, any imprecision in the initial stopping point of the carriage 600 may be accounted for by the centering effect created by the interaction between the pegs 626 of the locator mechanism 624 and the cylinder of the engagement mechanism 628. Accordingly, movement of the carriage 600 along the rail 616 may be restrained by interaction between the fixed engagement mechanism 628 and the locator mechanism 624 coupled to the carriage.
Note that locking apparatus may comprise various other mechanisms configured to center the carriage with respect to the engagement mechanism. For example, the locator mechanism may comprise a vertically oriented groove. Alternatively or additionally, the engagement mechanism may comprise an angled member such as a triangle.
Accordingly, the carriages 600 may be employed to transport the base 204 to various substations at which various components are assembled thereto. Thereby, the base 204 may be loaded into the carriage 600 as illustrated in
In this regard, as described above, the control component terminal 206 and the first and second heating terminals 234a,b may be inserted into the base 204 at the terminal coupling substation 504. In some embodiments the first heating terminal 234a, the second heating terminal 234b, and/or the control component terminal 206 may be provided from substantially continuous inputs. More particularly, the first heating terminal 234a may be supplied from a substantially continuous first heating terminal input, the second heating terminal 234b may be supplied from a substantially continuous second heating terminal input, and/or the control component terminal 206 may be supplied from a substantially continuous control component terminal input. Note that the term substantially continuous, as used herein in relation to certain specified inputs, refers to a configuration in which the referenced input defines a strip, chain, or other grouping of interconnected underlying components such that individual components may be singulated therefrom.
By way of example,
The couplers 704 may be cut to release an individual first heating terminal 234a from the substantially continuous first heating terminal input 700. Further, the carrier 702 may comprise apertures 706, grooves, cutouts, or other mechanisms configured to facilitate movement of the substantially continuous first heating terminal input 700 such that individual first heating terminals 234a may be removed therefrom. In this regard, as illustrated in
After insertion into the base 204, the terminal sealing substation 506 may seal one or more of the terminals 206, 234a,b with respect to the base, in some embodiments, in order to prevent liquid ingress or egress past the terminals. However, in some embodiments only the heating terminals 234a,b may be sealed. For example, in the illustrated embodiment the control component terminal 206 may extend through, or be positioned adjacent to, an opening through the base 204 through which a user draws air through the cartridge 200 during use thereof. Accordingly, the control component terminal 206 may not be sealed with respect to the base 204 in order to prevent blocking the opening extending through the base. Further, the control component terminal 206 may not be in contact with the liquid-filled reservoir substrate 214, such that liquid egress past the control component terminal 206 may not be of concern.
As illustrated in
In some embodiments the sealant may comprise a hot melt adhesive comprising polyolefins including atactic polyalphaolefins, polyurethane, ethylene-vinyl acetate (EVA), metallocene polyalphaolefins, block copolymers, and/or polyamides. Thus, the terminal sealing substation 506 may further comprise a heater 814 (see,
After the droplets of the liquid sealant contact the heating terminals 234a,b and/or the base 204, the droplets may dry in place relatively quickly. Further, the droplets may not contact one another. Thus, a complete seal around the full interface of the heating terminals 234a,b with the base 204 may not be formed by the initial application of the droplets of the sealant. Accordingly, the terminal sealing substation 506 may further comprise a re-melting device such as a hot air gun 816 configured to direct a flow of heated air at the sealant after application thereof to the heating terminals 234a,b and/or the base 204. Accordingly, the hot air from the hot air gun 816 may re-melt the sealant and blow the melted sealant around the heating terminals 234a,b such that the interface between the heating terminals and the base 204 is fully sealed around the perimeter of each of the heating terminals. In this regard, the hot air gun 816 may move relative to the base 204 and the heating terminals 234a,b. In some embodiments the hot air gun 816 may be configured to move. However, as illustrated, in another embodiment the hot air gun 816 may be stationary. Accordingly, the robotic arm 804 may move the base 204 relative to the hot air gun 816 such that hot air re-melts the sealant and directs the sealant around the interface between the heating terminals 234a,b and the base. Thus, the sealant may re-solidify and seal any gaps between the heating terminals 234a,b and the base 204.
Note that the terminal sealing substation 506 may additionally or alternatively seal the control component terminal 206 and/or any other component of the cartridge 200 with respect to the base 204. Additionally, although the re-melting device is described above as being the hot air gun 816, in other embodiments the sealant may be re-melted by other methods and other re-melting devices, such as by applying ultrasonic vibrations with an ultrasonic vibration device and/or applying radiant heat with a radiant heater. Further, although the sealant is described above as being a hot melt adhesive, various other embodiments of sealants may be employed. For example, the sealant may comprise an epoxy or an electrical potting material. After the heating terminals 234a,b are sealed, the base 204 may be returned to the carriage 600 by the robotic arm 608.
Thereafter, the control component coupling substation 508 may couple the electronic control component 208 to the control component terminal 206 (e.g., by vertically inserting the control component into a slot defined by the control component terminal). Then the flow tube coupling substation 510 may couple the flow tube 210 to the partially assembled cartridge. For example, the flow tube 210 may be inserted horizontally, such that the heating terminals 234a,b are slightly spread apart and then snap into place in longitudinal grooves defined in the flow tube, with a horizontal slot in the flow tube engaging the top of the electronic control component 208.
Next, the partially assembled cartridge may be transported to the heating element coupling substation 512 at which the heating element 240 may be coupled to the heating terminals 234a,b. In this regard,
As illustrated in
As illustrated, the substantially continuous heating element input 906 may be supplied from a spool 908 in some embodiments. The spool 908 may passively rotate as the substantially continuous heating element input 906 is pulled therefrom. Alternatively, the spool 908 may be actively rotated (e.g., by a motor) such that the spool rotates as the substantially continuous heating element input 906 is pulled therefrom. By either actively rotating the spool 908 or passively allowing the spool to substantially freely rotate as the substantially continuous heating element input 906 is pulled therefrom, tension in the substantially continuous heating element input may be controlled. In this regard, applying too much tension to the substantially continuous heating element input 906 may damage the heating elements 240 or the liquid transport element 238. For example, spacing of the coils of the heating elements 240 may be altered, which may make it difficult to attach the heating elements to the heating terminals. Further, too much tension in the liquid transport element 238 may cause breakage thereof, or stretching of the liquid transport element may reduce the diameter thereof and affect the ability of the liquid transport element to draw the aerosol precursor composition to the heating element 240. Accordingly, the substantially continuous heating element input 906 may be supplied to the preparing portion 902 without damaging the heating elements 240 or the liquid transport element 238 by controlling the tension therein.
However, as described above, in the illustrated embodiment the substantially continuous heating element input 906 may include a coil of wire wrapped about a substantially continuous liquid transport element. Thereby, the substantially continuous heating element input 906 may be cut to remove an individual heating element 240 and liquid transport element 238 therefrom. In this regard, as illustrated, the preparing portion 902 of the heating element coupling substation 512 may include a dispenser 910, a cutter 912, and an imaging device 914 (e.g., a camera).
In this regard, the imaging device 914 may be positioned and configured to capture images of the substantially continuous heating element input 906 as it is dispensed. The controller 417 (see, e.g.,
In this regard, the dispenser 910 may be configured to start dispensing the substantially continuous heating element input 906 and the controller 417 may analyze the images thereof and direct the dispenser to stop dispensing the substantially continuous heating element input when a desired length thereof has been dispensed. For example, the controller 417 may be configured to analyze the image captured by the imaging device 914 to detect coils or other features of the heating element 240. By way of further example, in one embodiment the controller 417 may be configured to detect a first contact portion 926 and a second contact portion 928 of the heating element 240, which are configured to engage the heating terminals. In one embodiment, the controller 417 may determine the position of inner edges 926a, 928a of the contact portions 926, 928 of the heating element 240. Thereby, the controller 417 may calculate a midpoint between the contact portions 926, 928 of the heating element 240 and allow the dispenser 910 to continue dispensing the substantially continuous heating element input 906 until the midpoint between the first contact portion 926 and the second contact portion 928 is aligned with the midpoint of the imaging device 914.
At this time, the controller 417 may direct the dispenser 910 to stop dispensing the substantially continuous heating element input 906. Additionally, the controller 417 may direct a transport apparatus 905 to grasp the substantially continuous heating element input 906. For example, the transport apparatus 905 may comprise a clamp 930 including first and second arms 932a, 932b configured to grasp the substantially continuous heating element input 906 outside of the contact portions 926, 928 of the heating element 240, which may allow the clamp to continue to hold the heating element during welding, as discussed below.
Further, the controller 417 may direct the cutter 912, which may comprise first and second blades 934a, 934b, to cut the substantially continuous heating element input 906 to singulate a heating element 240 and liquid transport element 238 having a desired length. In this regard, the imaging device 914 may be positioned such that when the midpoint between the first contact portion 926 and the second contact portion 928 of the heating element 240 is aligned with the midpoint of the imaging device, a distance between an end of the substantially continuous heating element input 906, as held by the clamp 920, and the blades 934a, 934b of the cutter 912 is equal to a desired length of a single heating element 240 and liquid transport element 238.
Note that the preparing portion 902 of the heating element coupling substation 512 may further comprise a tube 936. The substantially continuous heating element input 906 may be supplied through the tube 936 to the cutter 912. Accordingly, after the substantially continuous heating element input 906 is cut, the tube 936 may support the substantially continuous heating element input proximate a new end thereof. Thereby, the clamping mechanism 910 of the transport apparatus 905 may release from the singulated heating element 240 and liquid transport element 238 and grasp the new end of the substantially continuous heating element input 906, such that the above-described operations may be repeated by the preparing portion 902 of the heating element coupling substation 512, as illustrated in
As further illustrated in
Note that although the heating element is described herein as being attached to the heating terminals 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 element may be attached 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.
As described above, carriages 600 may travel along a rail 616 to various substations. In this regard, as further illustrated in
However, in order to facilitate welding the heating terminals to the heating element, it may be desirable to align the heating terminals in a desired configuration. In this regard, as illustrated in
Note that in the embodiment illustrated in
While the heating terminals 234a, 234b are clamped in plane at a desired spacing using the terminal fixation mechanism 944, the transport apparatus 905 may hold the singulated heating element 240 and liquid transport element 238 with the clamp 930 such that the heating element is in view of the imaging device 942 (see,
Similarly, the location of the heating terminals 234a, 234b may be determined. In this regard, as illustrated in
Thus, the transport apparatus 905 may move the heating element 240 and the liquid transport element in position for welding the heating element to the heating terminals 234a, 234b. In this regard, the controller 417 may direct the transport apparatus 905 to align the midpoint between the first heating terminal tab 952a and the second heating terminal tab 952b with the midpoint between the first contact portion 926 and the second contact portion 928. Further, the controller 417 may direct the transport apparatus 905 to bring the heating element 240 into engagement with the heating terminal tabs 952a, 952b. In particular, the transport apparatus 905 may engage the first contact portion 926 of the heating element 240 with the first heating terminal tab 952a and engage the second contact portion 928 with the second heating terminal tab 952b. In some embodiments the controller 417 may direct the transport apparatus 905 to press the heating element 240 against the heating terminal tabs 952a, 952b such that the heating terminals 234a, 234b are displaced slightly (e.g., a distance from about 0.002 inches to about 0.006 inches, and preferably about 0.004 inches). In this regard, by pressing the heating element 240 against the heating terminal tabs 952a, 952b (e.g., in a direction perpendicular to a substantially planar front face thereof, contact between the heating element and the heating terminals 234a, 234b may be assured.
Accordingly, as illustrated in
Note that the heating element 240 illustrated in
A center portion 929 of the heating element 240, defined between the contact portions 926, 928, may function to produce heat when current is supplied therethrough via the heating terminals 234a, 234b. The spacing of the coils at the center portion 929 of the heating element 240 may be greater than the spacing of the coils at the contact portions 926, 928 since the center portion is not employed for affixation to the heating terminals 234a, 234b. However, the spacing of the coils at the center portion 929 of the heating element 240 may be less than a spacing of optional coils at outer portions 931a, 931b of the wire positioned outside of the contact portions 926, 928 of the heating element. In this regard, the outer portions 931a, 931b may not produce heat or facilitate affixation to the heating terminals 234a, 234b, and hence the spacing of the coils may be relatively large in order to decrease material usage of the wire in the formation of the heating element 240. Rather, the outer portions 931a, 931b may be provided for ease of manufacturing the substantially continuous heating element input 906 (see, e.g.,
Note further that the above-described coil spacing, which may be applicable to any of the atomizers described herein, may not be uniform throughout each portion of the wire. In this regard, some variation may exist in the coil spacing in one or more of the portions of the wire. For example, the spacing of the coils may vary across the center portion of the heating element. Accordingly, by way of further example, the differences in coil spacing described above may refer to the average coil spacing for each of the portions of the wire.
Following welding, the carriage 600 with the partially assembled cartridge 200 may be directed to the liquid transport element bending substation 514. The liquid transport element bending substation 514 may be configured to bend the liquid transport element 238 such that the ends thereof extend down the heating element terminals 234a, 234b. However, the liquid transport element 238 and/or the wire wound thereon may be somewhat resilient and tend to bend back to an initial straight configuration following bending thereof.
In this regard, as illustrated in
Following bending of the liquid transport element 238 and retention of the liquid transport element in the bent configuration with the pivotable arms 632a, 632b, the carriage 600 may be directed to the reservoir coupling substation 516. As illustrated in
Further, when the moveable clamp 1008 reaches the lower limit, the stationary clamp 1009 grips the substantially continuous reservoir substrate input 1004. Accordingly, the substantially continuous reservoir substrate input 1004 is prevented from moving during cutting thereof into an individual reservoir having a desired length. Further, the stationary clamp 1009 may prevent undesirable upward movement of the substantially continuous reservoir substrate input 1004 by continuing to hold the substantially continuous reservoir substrate input as the moveable clamp 1008 returns to the upper limit. Once the moveable clamp 1008 reaches the upper limit and grips the substantially continuous reservoir input 1004, the stationary clamp 1009 may release the substantially continuous reservoir substrate input to allow the moveable clamp to pull the predefined quantity of the substantially continuous reservoir substrate input downwardly into the cutter 1010, as described above.
Following singulation, a transfer mechanism 1012 may receive the reservoir substrate. As illustrated in
As illustrated in
After receiving the reservoir substrate from the transfer mechanism 1012, the wrapping mechanism 1016 may spin around (e.g., about 180 degrees) such that the head portion 1022 thereof is positioned proximate the rail 616, as illustrated in
The interaction of the wrapping mechanism 1016 and the fingers 1024a, 1024b of the reservoir coupling substation 516 with the reservoir substrate 214 is schematically illustrated in
The flow tube 210 may be asymmetrical. In this regard, the flow tube 210 may define a shortened side 210a and an elongated side 210b (see, e.g.,
Note further that the heating terminals 234a, 234b may be oriented relative to the wrapping mechanism 1016 such that when the reservoir substrate 214 is wrapped about the partially assembled cartridge, the liquid transport element 238 is forced into further engagement with the heating terminals. In this regard, as illustrated by arrows 1036a, 1036b, the liquid transport element 238 may be pressed by the reservoir substrate 214 into inner corners defined by the heating elements 234a, 234b. More particularly, as illustrated, the heating elements 234a, 234b may include substantially perpendicularly extending walls defines an “L-shape,” and the liquid transport element 238 may be forced into an inner corner between the two walls. Accordingly, wrapping the reservoir substrate 214 about the partially assembled cartridge may assist in positioning the liquid transport element 238 in a desired position (e.g., a position wherein the liquid transport element extends substantially parallel to a longitudinal length of the heating terminals 234a, 234b).
The fingers 1024a, 1024b may be configured to engage the reservoir substrate 214 and further wrap the reservoir substrate about the flow tube 210 and/or the remainder of the partially assembled cartridge. For example, as illustrated in
After the reservoir substrate 214 is wrapped about the flow tube 210 and the atomizer 212 and/or other components of the cartridge, the outer body coupling substation 518 may couple the outer body to the base. In this regard, as illustrated in
Further, the outer body coupling substation 518 may include an outer body supply mechanism 1104, as illustrated in
The outer body coupling tool 1102 may comprise multiple sections (e.g. two or more sections) which cooperate to receive the outer body 216 by radially separating from one another. In this regard,
Accordingly, as illustrated in
As illustrated, in some embodiments one or both of the fingers 1024a, 1024b may engage the reservoir substrate 214 such that the reservoir substrate remains at least partially wrapped about the atomizer when beginning to insert the reservoir substrate through the outer body coupling tool 1002 into the outer body 216. In this regard, the finger(s) 1024a, 1024b may prevent the reservoir substrate 214 from unwrapping as the outer body 216 is inserted over the reservoir substrate. However, the fingers 1024a, 1024b may release from the reservoir substrate 214 after the outer body 216 has received the reservoir substrate a predefined distance therein (e.g., when the reservoir substrate is halfway into the outer body), at which time risk of the reservoir substrate unwrapping is substantially reduced.
Note that in some embodiments multiple sets of fingers 1024a, 1024b, 1024a′, 1024b′, 1024a″, 1024b″ may be employed to hold the reservoir substrate 214 in the wrapped configuration, as illustrated in
Further, in some embodiments the outer body coupling tool 1102 may twist during insertion of the reservoir substrate 214 through the outer body coupling tool into the outer body 216, as illustrated in
Following insertion of the reservoir substrate 214 and the other components of the cartridge into the outer body 216, the outer body may be coupled to the base 204. In this regard, the outer body coupling substation 518 may further comprise a crimper 1118, as illustrated in
Accordingly,
As illustrated, the cartridge assembly subsystem 402′ may include a base load substation 1202, a terminal coupling substation 1204, a terminal sealing substation 1206, a control component coupling substation 1208, a flow tube coupling substation 1210, a heating element coupling substation 1212, a liquid transport element bending substation 1214, a reservoir coupling substation 1216, and an outer body coupling substation 1218. Further, the controller 417 may be configured to control one or more of the substations 1202-1218 of the cartridge assembly subsystem 402′. Accordingly, the cartridge assembly subsystem 402′ may be similar to the cartridge assembly subsystem 402 described above and illustrated in
In this regard, the cartridge assembly subsystem 402 described above generally assembled cartridges upwardly from a carriage 600 transported between various subsystems. More particularly, the carriage 600 would generally pause at each substation, such that the base 204 was in a stationary position with the components moved into contact therewith from above.
However, the cartridge assembly subsystem 402′ described hereinafter differs in that the base 204 is generally directed into contact with stationary components to form a cartridge. In particular, the base 204 may be inverted and directed generally downwardly to engage the components therewith to form the cartridge in some embodiments.
For example, as illustrated in
As illustrated in
As noted above, in some embodiments portions of the cartridge assembly subsystem 402′ may be configured to grasp the base 204 such that the base is inverted during assembly of the cartridge. Additionally or alternatively, portions of the cartridge assembly subsystem 402′ may be configured to grasp an internal surface 204a′ of an attachment end 204a of the base 204 (see,
In this regard,
The terminal coupling substation 1204 may comprise the control component terminal robot 1302. As illustrated in
In this regard, as illustrated in
Following singulation, the first control component terminal 206a may be held in a stationary position to facilitate coupling with the base 204. More particularly, the first control component terminal 206a may be pinched between backing member 1608 and an opposing pressure pad 1610. In this regard, one or both of the opposing pressure pad 1610 and the backing member 1608 may move toward the first control component terminal 206a such that the first control component terminal is pinched therebetween. As illustrated, the opposing pressure pad 1610 and the backing member 1608 may define a contour that matches each of the control component terminals 206, such that the control component terminal may be securely held in place without affecting the shape of the control component terminal. Thereby, the base 204 may be directed into contact with the singulated control component terminal 206. For example, the control component terminal robot 1302 may direct the base 204 downwardly into contact with the stationary control component terminal 206, such that the control component terminal engages the base.
The terminal coupling substation 1204 may further comprise the heating terminal robot 1304. In this regard, after the control component terminal robot 1302 couples the control component terminal 206 to the base 204, the control component terminal robot may transfer the base to the heating terminal robot 1304. In some embodiments a transfer member may facilitate transfer of the base 204 from the control component robot 1302 to the heating terminal robot 1304.
As illustrated in
In this regard, by depositing the base 204 in the fixture 1704, the base may be positioned such that the heating terminal robot 1304 may grasp the base in substantially the same manner as that employed by the control component terminal robot 1302 to grasp the base. For example, the heating terminal robot 1304 may include a base gripper, such as the above-described base gripper 1500. Thereby, the base 204 may be directed by the heating terminal robot 1304 into contact with the first and second heating terminals 234a, 234b (see, e.g.,
The base 204 may then be engaged by the robotic arm 1306. The robotic arm 1306 may deposit the base 204 on a third transfer member 1700C, which may be substantially similar to the previously-described transfer members 1700A, 1700B. Further, in some embodiments the robotic arm 1306 may comprise part of the terminal sealing substation 1206, in embodiments in which sealing of the heating terminals 234a, 234b with respect to the base 204 is employed. In this regard, the terminal sealing substation 1206 may function in substantially the same manner as the terminal sealing substation 506 described above, wherein the robotic arm 1306 functions in substantially the same manner as the robotic arm 808 (see, e.g.,
Regardless of whether or not the terminal sealing substation 1206 is employed, the robotic arm 1306 may deposit the base 204 on the third transfer member 1700C. Thereafter, the base 204 may be directed to the control component coupling substation 1208 and the flow tube coupling substation 1210. In the illustrated embodiment, both the control component coupling substation 1208 and the flow tube coupling substation 1210 include and employ the control component and flow tube robot 1308.
In this regard, as illustrated in
Further, the control coupling substation 1208 may include a control component supply 1802 (see,
As further illustrated in
Accordingly, as illustrated in
Thereby, as further illustrated in
After coupling of the electronic control component 208 to the control component terminal 206, the base 204 may be directed by the control component and flow tube robot 1308 to the flow tube coupling substation 1210. As illustrated in
The flow tube coupling substation 1210 may further comprise a base 1904, as illustrated in
Thereafter, the heating element robot 1310 may engage the partially assembled cartridge. In this regard, as illustrated in
In this regard, as illustrated in
Accordingly, as illustrated in
Further, by grasping the heating terminals 234a, 234b in the above-described manner, the heating terminal tabs 952a, 952b may be configured in a desired position for attachment of the heating element thereto. In this regard, as described above, the flow tube gripper 1906 may press the heating terminals 234a, 234b against the flow tube 210. Thereby, when the terminal gripper 2002 grasps the heating terminals 234a, 234b, the heating terminal tabs 952a, 952b may define a desired separation therebetween, as defined by the width of the flow tube 210. Further, when the terminal gripper 2002 presses against opposing sides of each of the heating terminal tabs 952a, 952b with the prongs 2006A, 2006B, the heating terminal tabs may be aligned.
The heating element coupling substation 1212 may include the above-described heating element robot 1310. Additionally, as illustrated in
As illustrated, the substantially continuous heating element input 2012 may be supplied from a spool 2014 in some embodiments. The spool 2014 may passively rotate as the substantially continuous heating element input 2014 is pulled therefrom. Alternatively, the spool 2014 may be actively driven (e.g., by a motor) such that the spool rotates as the substantially continuous heating element input 2012 is pulled therefrom. By either actively rotating the spool 2014 or passively allowing the spool to substantially freely rotate as the substantially continuous heating element input 2012 is pulled therefrom, tension in the substantially continuous heating element input may be controlled to avoid damage thereto.
In one embodiment the position of the substantially continuous heating element input 2012 may be monitored such that the spool 2014 may actively supply the substantially continuous heating element input to maintain a desired amount of slack therein. For example, as illustrated in
As noted above, the preparing portion 2008 of the heating element coupling substation 1212 may be substantially similar to the preparing portion 902 described above. In this regard, the preparing portion 2008 may be configured to prepare an individual heating element 240 coupled to the liquid transport element 238 for welding. Accordingly, the preparing portion 2008 will not be described in detail.
Briefly, however, as illustrated in
The cutter 2020 may cut the substantially continuous heating element input 2012 to singulate an individual heating element 240 and liquid transport element 238. A new end of the substantially continuous heating element input 2012 may be supported by a tube 2028, as illustrated in
As illustrated in
Accordingly as illustrated in
Further, the chamber 2032 defined by the housing 2030 may be substantially sealed before welding the heating element 240 to the first heating terminal 234a and the second heating terminal 234b. In this regard, as illustrated in
Following welding, the partially assembled cartridge may be transported to the liquid transport element bending substation 1214. In this regard, the heating element robot 1310 may transport the partially assembled cartridge thereto in some embodiments.
The heating element robot 1310 may be configured to direct the partially assembled cartridge between the upright members 2102a, 2102b of the liquid transport element bending substation 1214. More particularly, the heating element robot 1310 may orient the partially assembled cartridge such that the liquid transport element 238 enters the upper channels 2104a, 2104b. As the partially assembled cartridge is inserted down between the upright members 2102a, 2102b, the liquid transport element 238 may begin to bend and enter the side channels 2106a, 2106b defined at inner surfaces of the upright members. Further, as illustrated in
Once the liquid transport element 238 is bent, the reservoir substrate robot 1312 may grasp the partially assembled cartridge. As illustrated in
In this regard,
The reservoir substrate robot 1312 may thus transport the partially assembled cartridge, with the liquid transport element 238 in the bent configuration, to the reservoir coupling substation 1216, where the reservoir substrate 214 is coupled thereto. Accordingly, the reservoir substrate 214 may be prepared for attachment to the partially assembled cartridge. In this regard, as illustrated in
In one embodiment the position of the substantially continuous reservoir substrate input 2302 may be monitored such that the spool 2304 may actively supply the substantially continuous reservoir substrate input to maintain a desired amount of slack therein. For example, as illustrated in
The substantially continuous reservoir substrate input 2302 may be supplied from the spool 2304 to a singulation unit 2310. As illustrated in
In this regard, as illustrated in
After transfer of a reservoir substrate 214 to the head portion 2324 of the moveable slide 2320, the moveable slide may begin moving back to an initial starting position. The reservoir substrate robot 1312 may bring the partially assembled cartridge into contact with the reservoir substrate 214 held by the head portion 2324 of the moveable slide 2320. Then the reservoir substrate robot 1312 and the moveable slide 2320 may move in a synchronized manner in the same direction until the moveable portion reaches the position illustrated in
Following wrapping of the reservoir substrate 214, the partially assembled cartridge may be directed to the outer body coupling substation 1218 by the outer body robot 1314. As illustrated in
The outer body supply 2402 may supply the outer bodies 216 to a transfer member 2404. The transfer member 2404 may be configured to grasp an individual outer body 216 and position the outer body for coupling to the partially assembled cartridge. In this regard, as illustrated in
In order to deposit the outer body 216 in the chamber 2410, as illustrated in
In this regard, the outer body coupling tool 2406 may comprise a plurality of sections. For example, in the illustrated embodiment the outer body coupling tool 2406 comprises first and second sections 2416a, 2416b. The sections 2416a, 2416b of the outer body coupling tool 2406 may be moveable between an expanded configuration (see, e.g.,
The outer body robot 1314 may include a gripper configured to facilitate the above-described insertion of the partially assembled cartridge through the outer body coupling tool 2406 into the outer body 216. In this regard,
Further, the reservoir substrate gripper 2420 may include a finger 2424 configured to retain the reservoir substrate 214 in the wrapped configuration. Note that the reservoir substrate is not illustrated in
The finger 2424 may be configured to retain the reservoir substrate 214 in the wrapped configuration. In this regard, the tip 2434 of the finger 2424 may be configured to press against the wrapped reservoir substrate 214 while the outer body robot 1314 transports the partially assembled cartridge to the outer body coupling substation 1218. In this regard, as illustrated in
Thereby, while the arms 2328a, 2328b hold the reservoir substrate in the wrapped configuration, the outer body robot 1314 may engage the partially assembled cartridge with the reservoir substrate gripper 2420. More particularly, the first and second body portions 2422a, 2422b may engage the base 204 of the partially assembled cartridge. Further, the tip 2434 of the finger 2424 may extend between or below the protrusions 2334a, 2334b to engage the reservoir substrate proximate a location at which the ends thereof overlap or meet at a joint. Accordingly, when the arms 2328a, 2328b of the wrapping mechanism 2318 retract, the reservoir substrate gripper 2420 may retain the reservoir substrate 214 in the wrapped configuration by pressing against the reservoir substrate.
Accordingly, the partially assembled cartridge may include the reservoir substrate 214 wrapped thereabout when insertion through the outer body coupling tool 2406 into the outer body 216 begins. However, the finger 2424 may be configured to release from the reservoir substrate 214 during insertion of the partially assembled cartridge into the outer body 216. In this regard, as the outer body robot 1314 inserts the partially assembled cartridge through the outer body coupling tool 2406, the finger 2424 of the reservoir substrate gripper 2420 may contact the outer body coupling tool. Accordingly, the first body portion 2422a may continue moving toward the outer body coupling tool 2406 while the finger 2424 remains in contact with the outer body coupling tool. Accordingly, the finger 2424 may move along a path relative to the first body portion 2422a defined by the interaction between the channel 2426 and the pin 2428 and between the elongated aperture 2430 and the pin 2432. Accordingly, the upper portion of the finger 2424 may remain substantially stationary as a result of the channel 2426 being substantially straight. However, a lower portion of the finger 2424 may be directed outward, away from the reservoir substrate 214 and the remainder of the partially assembled cartridge as a result of the elongated aperture 2430 defining a path that extends upward and away from the tip 2434 of the finger. Accordingly, the tip 2434 of the finger 2424 may deflect away from and release the reservoir substrate 214 as the outer body robot 1314 inserts the partially assembled cartridge through the outer body coupling tool 2406.
Note that the particular embodiment of the reservoir substrate gripper 2420 may vary while still operating in a manner similar to that described above. For example,
Once the partially assembled cartridge is inserted into the outer body 216, the crimper 2408 may crimp the outer body to the base 204. In this regard, as illustrated in
Note that the above-described cartridge assembly sub-systems 402, 402′ may be combined and modified in a number of manners without varying from the scope of the present disclosure. In this regard, the heating element has been generally described above as being provided as a substantially continuous coil of wire wound about a substantially continuous liquid transport element. Thus, preparation of individual heating elements 240 and liquid transport elements 238 involved cutting a substantially continuous input into sections. However, in other embodiments the heating elements may be formed by the cartridge assembly subsystem.
For example, as illustrated in
Accordingly, the above-described process may produce a heating element 240′ coupled to a liquid transport element 238, which may form a completed atomizer when heating terminals (e.g., heating terminals 234a, 234b) are coupled thereto (e.g., in via the processes disclosed herein). In this regard, as described above, the wire 242 may extend at least partially through the liquid transport element 238 at one or both of first and second ends 240A, 240B of the wire. Thus, the ends of the wire 242 may extend through the liquid transport element 238 substantially transversely to a longitudinal length of the liquid transport element. The liquid transport element 238 may extend between first and second opposing ends 238A, 238B. However, the wire 242 may not extend to the opposing ends of the liquid transport element (note that a section of the transport element is shown in
Following attachment of the outer body 216 to the base, the partially assembled cartridge may be directed to the cartridge filling substation 408. The cartridge filling substation 408 may include one or more fill stations. As illustrated in
In one embodiment the environment modification apparatus 2506 may comprise a dehumidifier configured to affect the ambient environment within the environment control housing 2504. By way of additional example, the environment modification apparatus 2506 may be configured to control the ambient environment within the environment control housing 2504 such that the ambient environment defines a relative humidity of less than about 60%, preferably less than about 50% and most preferably less than about 40%. By controlling the humidity in this manner, issues with respect to the aerosol precursor composition absorbing ambient moisture, which may undesirably dilute the aerosol precursor composition and/or overfill the cartridge, may be avoided.
In one embodiment, the outlet 2508 of the filling device 2510 may be sequentially moved from each of the first through fourth angular portions 2512a-d at filling station one 2502a. Thereafter, filling stations two through five 2502b-e may position the outlet 2508 of the filling device 2510 at one of the angular portions. For example, filling station two 2502b may position the outlet 2508 of the filling device 2510 at the first angular portion 2512a, filling station three 2502c may position the outlet 2508 of the filling device 2510 at the second angular portion 2512b, filling station four 2502d may position the outlet 2508 of the filling device 2510 at the third angular portion 2512c, and filling station five 2502e may position the outlet 2508 of the filling device 2510 at the fourth angular portion 2512d. Accordingly, the cartridge may be transported between the filling stations 2502a-e and the flow of the aerosol precursor composition may be directed to at least one of the angular portions 2512a-d of the reservoir substrate 214 at each of the filling stations.
Further, as illustrated in
After filling, the cartridge may be directed to the cartridge capping subsystem 412, at which the mouthpiece 220 is coupled to the outer body 216. The outer body 216 may be crimped to the mouthpiece 220 using a crimper substantially similar to the above-described crimpers in order to prevent leakage between the outer body and the mouthpiece. Further, the cartridge labeling subsystem 416 may apply a label 218 to the cartridge in some embodiments.
Various quality control measures may be employed to ensure that the completed cartridges 200 are suitably constructed. In this regard, as noted above and illustrated in
In this regard, imaging devices (e.g., cameras) may be employed at a variety of locations to ensure that the above-described processes are being performed as desired, within specifications. Thus, cameras and/or other inspection equipment may be employed at a plurality of locations within the system 400. However, inspection at certain locations may be of particular importance.
In this regard, it may be important to inspect the position of the terminals 206, 234a, 234b after insertion into the base 204. For example, one or more cameras may be configured to inspect a radial position of each of the terminals 206, 234a, 234b (e.g., with respect to a center of the base 204). The radial position of the terminals 206, 234a, 234b may be determined at an attachment end 204a of the base 204. In this regard, proper radial position of the terminals 206, 234a, 234b may facilitate attachment of the cartridge 200 to the control component 300. Further, one or more cameras may be employed to inspect the distance to which the terminals 206, 234a, 234b extend from the base 204. The distance to which the terminals 206, 234a, 234b extend from the base 204 may be determined at an inner end 204b (see,
In the cartridge assembly subsystem 402, the terminals 206, 234a, 234b are downwardly inserted into the base 204. Accordingly, inspection of the distance to which the terminals 206, 234a, 234b extend from the inner end 204b of the base 204 may be conducted while the base is held in the carriage 600 traveling on the rail 616. In this regard, as illustrated in
However, as a result of the attachment end 204a of base 204 being downwardly oriented toward the carriage 600, the base may be removed from the carriage to inspect the radial position of the terminals 206, 234a, 234b. In this regard, as illustrated in
In the second embodiment of the cartridge assembly subsystem 402′, the cartridge is generally assembled with the base 204 oriented in an opposing manner such that components coupled thereto extend downwardly therefrom. In this regard, as illustrated in
Further, as illustrated in
The inspection subsystem 418 may additionally include one or more cameras configured to inspect the partially assembled cartridge following crimping of the outer body 216 to the base 204. For example, as illustrated in
Further, the cartridge assembly subsystem 402 may include a side view camera 2804 configured to capture images of a side of the partially assembled cartridge. In this regard, the side view camera 2804 may be positioned beside the rail 616 such that the side view camera may capture images of the partially assembled cartridge held by the carriage 600. In this regard, a controller may be configured to analyze the images captured by the side view camera 2804 to determine whether a crimp in the outer body 216 produced by the crimper 1118 is proper (e.g., when the crimp is proper the outer body may be substantially flush with the base 204) and further the controller may determine whether the reservoir substrate 214 sticks out of the outer body (e.g., at the interface between the outer body and the base), which is an undesired condition, or contained within the outer body, which is a desired condition.
As illustrated in
The inspection subsystem 418 may additionally include a blow-through station. The blow-through station may be configured to direct a flow of air through the cartridge to purge the flow path defined therethrough. In this regard, although not expected, the blow-through station may remove any dust or debris from the flow path through the cartridge. By way of example,
The connectors 3002, 3004 may be at differing pressures. Accordingly, a pressure differential applied across the cartridge through the connectors 3002, 3004 may cause a flow of air to be directed therethrough. In some embodiments the first connector 3002 may be at a higher pressure than the second connector 3004 such that air flows through the cartridge in the same direction as would occur during normal use of the cartridge. For example, vacuum may be applied to the second connector 3004, whereas the first connector 3002 may be ambient pressure. Accordingly, any debris in the cartridge may be removed.
Further, the inspection subsystem 418 may additionally include a pressure drop station. The pressure drop station 418 may be configured to detect a pressure drop associated with directing airflow through the partially assembled cartridge. Accordingly, a pressure drop associated with the cartridge may be determined and compared to a desired pressure drop to ensure that there are not any obstructions or leaks in the cartridge.
In some embodiments the pressure drop station may be substantially similar to the flow-through station. In this regard,
One of the connectors 3202, 3204 may supply air to the cartridge at a known flow rate and/or pressure. Further, the flow rate and/or the pressure of the air traveling through the other of the connectors 3202, 3204 may be tested to determine the pressure drop associated with the cartridge. Thereby, the pressure drop may be compared to a desired pressure drop.
Further, the inspection subsystem 418 may additionally include an electrical test station. In this regard,
As illustrated, the test fixture 3402 may comprise a plurality of electrical contacts coupled to the receptacle 3408 and configured to engage terminals of the cartridge. For example, a first electrical contact 3410 may be configured to engage the first heating terminal 234a, a second electrical contact 3412 may be configured to engage the second heating terminal 234b, and a third electrical contact 3414 may be configured to engage a control component terminal 206. The first electrical contact 3410 may be defined by a first body portion 3416, the second electrical contact 3412 may be defined by a second body portion 3418, and the third electrical contact 3414 may be defined by a third body portion 3420. The body portions 3416, 3418, 3420 may be formed from conductive and relatively hard material, such as hardened steel, in order to withstand repeated use and allow for electrical communication therethrough in the manner described below.
Each of the body portions 3416, 3418, 3420 may be coupled to a nonconductive member 3422, which may be formed from any of a variety of nonconductive materials such as plastic. Further, the body portions 3416, 3418, 3420 may be electrically insulated from another by avoiding direct contact therebetween. In this regard, the body portions 3416, 3418, 3420 may be positioned such that air gaps are defined therebetween. For example, the body portions 3416, 3418, 3420 may be coupled to the nonconductive member 3422 such that the body portions are spaced apart from one another when coupled to the nonconductive member. Alternatively or additionally, nonconductive spacers may be placed between the body portions 3416, 3418, 3420.
The test fixture 3402 may be in communication with a controller such as the above-described controller 417 (see, e.g.,
The test fixture 3402 may further comprise an aperture 3426 configured to provide for a flow of air through the base 204 of the cartridge. Accordingly, in some embodiments the test fixture 3402 may be employed to perform the above-described flow-through and/or pressure drop operations. Thus, for example, the aperture 3426 in the test fixture may be in communication with a first connector and the outer body gripper 3406 may include a second connector, such that an air flow may be provided through a cartridge held by the test fixture 3402 and the outer body gripper.
Further, the controller 417 may be configured to transmit program code instructions to the electronic control component 208 of the cartridge through the third electrical contact 3414 and the control component terminal 206. Accordingly, for example, a heating profile defining when and how much current to apply to the atomizer upon detection of a puff may be written to the electronic control component 208. Additionally, the program code instructions may include an authentication code, which may be employed to verify that the cartridge is authentic. The controller 417 may be further configured to read program code instructions stored on the electronic control component 208 and determine whether the program code instructions stored on the electronic control component correspond to desired program code instructions. For example, reading the stored program code instructions may be employed to ensure that the proper heating profile and authentication code are stored. A unique identifier associated with the electronic control component 208 may also be read therefrom, which may be employed to record information regarding the cartridge (e.g., manufacture date, heater profile, authentication code, etc.) in a database. The controller 417 may also initialize the electronic control component 208 such that the electronic control component directs current to the atomizer upon detection of a first puff, rather than a second puff, which may occur when the electronic control component is not initialized.
In some embodiments the inspection subsystem 418 may additionally include a quality assurance station. The quality assurance station may be positioned at any point in the assembly process. For example, the quality assurance station may be positioned downstream of the crimper 1118, 2408 that crimps the outer body 216 to the base 204. However, the quality assurance station may be configured to receive partially assembled cartridges in various states of completion. In this regard, the various substations of the cartridge assembly subsystems 402, 402′ may be configured to direct the cartridges to quality assurance station in any of the various states of completion occurring during the assembly thereof. Thus, for example, a base 204 with the terminals 206, 234a, 234b coupled thereto may be directed to the quality assurance station without the electronic control component, flow tube, reservoir substrate, and outer body coupled thereto. By way of further example, the carriages 600 of the first embodiment of the cartridge assembly subsystem 402 may skip various stations, and/or some of the robots of the second embodiment of the cartridge assembly subsystem 402′ may transfer the partially assembled cartridge to the quality assurance station without performing operations thereon. The partially assembled cartridges directed to the quality assurance station may be inspected manually, or via automated processes, to ensure that the cartridges are being properly assembled. In some embodiments the partially assembled cartridges, defining various states of completion, may be directed to the quality assurance substation at predefined intervals, such that partially assembled cartridges in each of various states of completion, may be regularly inspected.
The inspection subsystem 418 may be configured to dispose of defective cartridges that fail to meet certain predefined standards, as described above. For example, after a partially assembled cartridge is identified as defective in the first embodiment of the cartridge assembly subsystems 402, the carriage 600 holding the defective cartridge may skip the remaining assembly stations and direct the cartridge to a reject station at which the defective cartridge is removed thereform (e.g., via a vacuum hose) for disposal. By way of further example, after a partially assembled cartridge is identified as defective in the second embodiment of the cartridge assembly subsystems 402′, a robot proximate the location at which the cartridge is determined to be defective may drop the defective cartridge in a waste receptacle. For example,
The inspection subsystem 418 may additionally inspect the cartridges following filling at the cartridge filling subsystem 408, capping at the cartridge capping subsystem 410, and/or labeling at the cartridge labeling subsystem 412. For example, the inspection subsystem 418 may be configured to detect leaks in the cartridge after filling. By way of further example, the inspection subsystem 418 may include a camera over which the filled cartridges are lifted and the captured images may be compared to stored images of known acceptable cartridges that do not have leaks. Additional cameras may ensure that the mouthpiece 220 is properly crimped to the outer body 216. For example, the crimp associated with attachment of the mouthpiece 220 to the outer body 216 may be inspected in substantially the same manner as the crimp employed to attach the base 204 to the outer body. Further, following application of the label 218 to the outer body 216, a camera may inspect the placement of the label to ensure that it is properly positioned.
