         [0003]    The present disclosure is directed to machines for seating a tire bead on a wheel, and related methods for bead seating. 
         [0004]    2. Brief Discussion of Related Art 
         [0005]    Various methods and machines have been devised for seating the bead of a tire on a wheel. Generally, it may be desirable to ensure that the bead, or inner rim, of the tire aligns with and/or seats within the bead seat on the wheel to permit proper functioning of the wheel/tire assembly. Due to the substantial friction between the tire (which may be made of rubber) and the wheel (which may be made of metal), lubrication may be used to aid in mounting a tire on a wheel. For example, some methods may include soaping the tire and wheel, installing the tire on the wheel, inflating the tire at least partially, and manipulating the tire in some manner to get the tire bead to seat on the wheel completely around the diameter of the wheel. U.S. Pat. No. 6,557,610, which is incorporated by reference into this Background section, may be related to tire bead seating.

     DETAILED DESCRIPTION 
       [0030]    The exemplary embodiments of the present invention are described and illustrated below to encompass machines for seating a tire bead on a wheel, and related methods for bead seating. Of course, it will be apparent to those of ordinary skill in the art that the preferred embodiments discussed below are exemplary in nature and may be reconfigured without departing from the scope and spirit of the present invention. However, for clarity and precision, the exemplary embodiments as discussed below may include optional steps, methods, and features that one of ordinary skill should recognize as not being a requisite to fall within the scope of the present invention. 
         [0031]    Referencing  FIGS. 1 and 2 , an exemplary wheel assembly  100  includes a rubber tire  102  mounted to a vehicle wheel  104 . In exemplary form, the tire  102  is inflated with air or nitrogen to a pressurized state well above atmospheric pressure to provide resistance to collapsing of the tire under a load. The tire  102  includes a tread section  106  that interposes right and left sidewalls  108 ,  110 . An exposed circumferential edge of each sidewall  108 ,  110  includes a bead  112  that is correspondingly received by circumferential bead seats  114  of the vehicle wheel  104 . 
         [0032]    Referring to  FIG. 3 , as is understood by those skilled in the art, a typical tire inflation station  140  conveys the wheel assembly  100  onto a stationary position beneath an overhead tire inflation head  150 . Centering arms (not shown) may thereafter engage the tire  102  and center it with respect to the inflation head  150 . The inflation head is then moved downwardly into engagement with one of the sidewalls  108 , thereby displacing the bead  112  from the bead seat  114 , and high pressure air is injected between the bead and bead seat  114  to inflate the tire  102 . A more detailed explanation of this process and equipment is found in U.S. Pat. No. 4,947,919, the disclosure of which is incorporated herein by reference. 
         [0033]    Referring to  FIGS. 2 ,  4  and  5 , an exemplary tire bead seating machine  200  is utilized to seat the tire  102  bead  112  of each sidewall  108 ,  110  with respect to the bead seat  114  of the vehicle wheel  104  after the tire has been inflated by the tire inflation station. By seating the bead  112 , the machine  200  ensures that an adequate seal is formed between the bead  112  and bead seat  114  that may have otherwise been compromised by soap or other debris interposing the bead and bead seat resulting from the tire inflation process and mounting the tire  102  onto the wheel  104 . 
         [0034]    The machine  200  includes a conveyor  202  utilized to reposition the wheel assembly  100  into and out of a working area  204 . In this exemplary embodiment, the conveyor  202  comprising a pair of spaced apart, parallel tracks  206  that each include a series of raised studs  208 . The tracks  206  ride upon a guide wheels (not shown) and are operative to move forward or rearward. The raised studs  208  operate to engage the wheel assembly  100  and retain the wheel assembly on the conveyor  202  as the wheel assembly is moved into or out of the working area  204 . 
         [0035]    Within the working area  204 , the machine  200  includes a lower wheel bed assembly  220 , which includes a plurality of rollers  222  arranged to horizontally support the wheel assembly  100 . In exemplary form, the rollers  222  comprise cylindrical rollers that are mounted to corresponding supports  224  that angle the rollers approximately five degrees from vertical and orient the rollers within a circular footprint of the wheel assembly  100 . More specifically, the rollers  222  are generally oriented in parallel to respective radius of the wheel assembly  100 . In this manner, the rollers  222  are adapted to contact an end of the lower sidewall  110  proximate the tread section  106 . 
         [0036]    The machine  200  also includes a plurality of drive roller assemblies  230  operative to selectively contact the tread section  102  of the wheel assembly  100  in order to rotate the wheel assembly while within the working area  204 . In this circumstance, there are four drive roller assemblies  230 A,  230 B,  230 C,  230 D, with two on each side of the machine  200 . It should be noted that each drive roller assembly  230  is substantially identical and accordingly only one drive roller assembly will be described in detail, with it being understood that the other assemblies are substantially identical in terms of construction and operation as described. 
         [0037]    An exemplary drive roller assembly  230  includes a cylindrical roller  232  mounted at opposing ends to a repositionable frame  234 . The repositionable frame  234  includes a block C-shaped section  236  with corresponding ends that receive corresponding ends of the cylindrical roller  232 . A spindle (not shown) mounted to and extending through the roller  232  is received within respective ends of the C-shaped section  236 . An end of the spindle is operatively coupled to a motor, such as an electric or hydraulic motor, that is operative to rotate the spindle thus rotate the roller  232 . In particular, the motor drives the spindle, thus rotating the roller  232  that is in contact with the tread portion  106  of the tire  102 . This rotation of the roller  232  causes the tire  102  to rotate about a central axis while being seated upon the drive roller assemblies  230 . 
         [0038]    In order to hold down the tire  102  while it is rotated by the drive roller assemblies  230 , the machine also includes a hold-down assembly  250  that includes a plurality of hold-down rollers  252 . In this exemplary embodiment, the hold-down assembly includes a pair of rollers  252  that are positioned opposite one another. It should be noted, however, that one or more than two rollers  252  may be utilized and oriented in any particular orientation. The hold-down assembly  250  is vertically repositionable to allow the hold-down rollers  252  to selectively engage an opposing sidewall  108  of the tire  102 . In exemplary form, the hold-down rollers  252  comprise frustoconical rollers that are mounted to corresponding supports  254  that angle the rollers approximately fifteen degrees from vertical and orient the rollers within a circular footprint of the wheel assembly  100 . More specifically, the rollers  252  are generally oriented in parallel to respective radius of the wheel assembly  100 . In this manner, the rollers  252  are adapted to contact an end of the upper sidewall  108  proximate the tread section  106  and maintain engagement with the wheel assembly  100  while the wheel assembly is rotated. 
         [0039]    Referring to  FIGS. 4-10 , in order to vertically reposition the hold-down rollers  252  and supports  254 , a repositionable platform  260  is mounted to the supports. In exemplary form, the platform  260  comprises an elongated plate having a cross-member  262  to which the corresponding supports  254  and hold-down rollers  252  are mounted. A predominant dimension of the platform  260  runs perpendicular to the direction of the cross-member, with the cross member being offset from the center of the platform. In order to vertically reposition the platform  260 , a pair of hydraulic or pneumatic cylinders  264  is mounted to a top side  266 . The hydraulic cylinders  264  are operative to reposition the platform  260  between a retracted position (see  FIG. 4 ) and a working (i.e., extended) position (see  FIG. 7 ). In the retracted position, the hold-down rollers  252  are elevated above the working area  204 . In contrast, when in the working position, the hold-down rollers  252  occupy a portion of the working area  204 . 
         [0040]    Referring specifically to  FIGS. 4 ,  9 , and  10 , an upper bead seating assembly  270  is also mounted to the repositionable platform  260 . The upper bead seating assembly  270  is mounted on a bottom side  272 , opposite the top side  266 . In exemplary form, the upper bead seating assembly  270  includes a pair of pneumatic actuators  274 ,  276  operative to reposition an upper bead seating roller  280 . Specifically, the first actuator  274  is mounted to the platform  260  and concurrently mounted to a repositionable carriage  282 . The carriage  282  is laterally repositionable along a track  284  extending parallel to the dominant dimension of the platform  260 . In other words, the mounting position of the first actuator  274  is fixed with respect to the platform and only a piston  286  of the first actuator is repositionable with respect to the platform. The piston is mounted to the repositionable carriage  282  and, thus, as the piston is repositioned (extended or contracted) laterally, so too is the carriage repositioned laterally. 
         [0041]    The carriage  282  includes a block  288  having a through passage occupied partially by an L-shaped bracket  290  and a pin  292  that concurrently extends through the L-shaped bracket and a portion of the block. Specifically, the L-shaped bracket  290  is pivotally mounted to the block  288  and pivots around the pin  292 . In contrast, the block  288  is mounted to the carriage  282  in a fixed orientation. A first end  294  of the L-shaped bracket  290  is mounted to a piston  296  of the second actuator  276 , while a second end  298  of the L-shaped bracket is mounted to a spindle  302 . As will be discussed in more detail hereafter, the spindle  302  is mounted to the second end  298  of the L-shaped bracket  290  in a non-perpendicular orientation. Specifically, the spindle  302  is angled at approximately five degrees with respect to a centerline  306  extending through the L-shaped bracket  290 . It should be noted that the centerline  306  extending through the L-shaped bracket  290  is parallel to radius extending from the center of the tire  102  when the platform  260  is lowered to a working position. The other aspect of the second actuator  276  is fixedly mounted to the carriage  282 , but the piston  296  is repositionable with respect to the carriage. 
         [0042]    In sum, the first actuator  274  is operative to laterally reposition the carriage  282 , while the second actuator  276  is operative to reposition the L-shaped bracket  290 . Repositioning of the L-shaped bracket  290  is operative to reposition the upper bead seating roller  280 , which is mounted to the spindle  302 , between a retracted position (see  FIG. 6 ) and a seating position (see  FIG. 8 ). As will be discussed in more detail hereafter, in operation, the upper bead seating assembly  270  is operative to seat the bead  112  with respect to the bead seat  114  on one side of the wheel assembly  100 . In order to seat the bead  112  with respect to the bead seat  114  on the opposite side of the wheel assembly  100 , the machine  200  includes a lower bead seating assembly  320 . 
         [0043]    Referring specifically to  FIGS. 4 ,  11 , and  12 , the lower bead seating assembly  320  is mounted to a frame of the machine laterally in-between the rollers  222 . In exemplary form, the lower bead seating assembly  320  includes a pair of pneumatic actuators  324 ,  326  operative to reposition a lower bead seating roller  328 . Specifically, the first actuator  324  is mounted to a fixed position platform  330  and concurrently mounted to a repositionable carriage  332 . The carriage  332  is laterally repositionable along a track  334  extending parallel to the dominant dimension of the platform  330 . In other words, the mounting position of the first actuator  324  is fixed with respect to the platform  330  and only a piston  336  of the first actuator is repositionable with respect to the platform. The piston  336  is mounted to the repositionable carriage  332  and, thus, as the piston is repositioned (extended or contracted) laterally, so too is the carriage repositioned laterally. 
         [0044]    The carriage  332  includes a block  338  having a through passage occupied partially by an L-shaped bracket  340  and a pin  342  that concurrently extends through the L-shaped bracket and a portion of the block. Specifically, the L-shaped bracket  340  is pivotally mounted to the block  338  and pivots around the pin  342 . In contrast, the block  338  is mounted to the carriage  332  in a fixed orientation. A first end  344  of the L-shaped bracket  340  is mounted to a piston  346  of the second actuator  326 , while a second end  348  of the L-shaped bracket is mounted to a spindle  352 . As will be discussed in more detail hereafter, the spindle  352  is mounted to the second end  348  of the L-shaped bracket  340  in a non-perpendicular orientation. Specifically, the spindle  352  is angled at approximately five degrees with respect to a centerline  356  extending through the L-shaped bracket  340 . It should be noted that the centerline  356  extending through the L-shaped bracket  340  is parallel to radius extending from the center of the tire  102  when the L-shaped bracket  340  repositioned to a working position. The other aspect of the second actuator  326  is fixedly mounted to the carriage  332 , but the piston  346  is repositionable with respect to the carriage. 
         [0045]    In sum, the first actuator  324  is operative to laterally reposition the carriage  332 , while the second actuator  326  is operative to reposition L-shaped bracket  340 . Repositioning of the L-shaped bracket  340  is operative to reposition the lower bead seating roller  328 , which is mounted to the spindle  352 , between a retracted position (see  FIG. 6 ) and a seating position (see  FIG. 8 ). As will be discussed in more detail hereafter, in operation, the lower bead seating assembly  320  is operative to seat the bead  112  with respect to the bead seat  114  on the opposite side of the wheel assembly  100 . 
         [0046]    Referring generally to  FIGS. 13 and 14 , an example method of seating a bead using the tire bead seating machine  200  of the instant disclosure includes transferring a single wheel assembly  100  into the machine at step  400 . As discussed briefly beforehand, the tire assembly  100  is positioned within the working area  204  of the machine  200  using the conveyor  202 . Specifically, the wheel assembly  100  is positioned on a portion of the conveyor  202  and conveyed toward the working area  204 . 
         [0047]    Referring to  FIGS. 5 and 13 , just before reaching the edge of the forward most rollers  222 , the studs  208  of the conveyor  202  are raised to elevate the wheel assembly  100  above the rollers  222 , while continuing to move the wheel assembly into the working area  204 . In this manner the wheel assembly  100  is elevated above the rollers and generally centered with respect to the rollers. Thereafter, the studs  208  of the conveyor  202  are lowered, resulting in one side of the tire  102  sitting upon the rollers  222 . 
         [0048]    At step  402 , the drive roller assemblies  230 A,  230 B,  230 C,  230 D are repositioned from a non-contact position (see  FIG. 4 ) to a contact position where the rollers  232  contact the tread portion  106  of the tire  102 . In this exemplary embodiment, the drive roller assemblies  230 A,  230 B,  230 C,  230 D are equidistantly positioned about the circumference of the tire  102 . 
         [0049]    Referencing  FIGS. 6 and 13 , at step  404 , while the rollers  230  contact the circumference of the tire  102 , the hold-down assembly  250  is lowered from a retracted position (see  FIG. 4 ) to a working position (see  FIG. 7 ) so that the hold-down rollers  252  contact the top circumferential edge between the sidewall  108  and the tread section  106 . 
         [0050]    At step  406 , the drive roller assemblies  230 A,  230 B,  230 C,  230 D are engaged so that the rollers  232  rotate and correspondingly rotate the tire  102 . 
         [0051]    Referring to  FIGS. 7 ,  8 , and  13 , at step  408  one or both of the bead seating assemblies  270 ,  320  are repositioned so that one or both bead seating rollers  280 ,  328  contacts a corresponding sidewall  1008 ,  110  of the tire  102 . In this exemplary process, the bead seating assemblies  270 ,  320  are concurrently repositioned so that both bead seating rollers  280 ,  328  contact respective sidewalls  108 ,  110  of the tire  102  at the same time. 
         [0052]    Referring to  FIG. 15 , an exemplary diagram shows the bead seating roller  280 ,  328  oriented coaxially with a radius  450  of the tire  102 . 
         [0053]    Referring to  FIG. 16 , the exemplary method includes angling the bead seating roller  280 ,  328  with respect to the radius  450  of the tire  102  between an angle θ of two degrees to an angle of approximately forty-five degrees. In exemplary form, the bead seating roller  280 ,  328  is shown angled at approximately five degrees with respect to the radius  450 . 
         [0054]    Referring back to  FIGS. 7 ,  8 , and  13 , by applying a positive force to a portion of the sidewalls  108 ,  110  in contact with the bead seating rollers  280 ,  328 , a gap is temporarily created between the bead  112  and the bead seat  114 . In this exemplary embodiment, the bead seating rollers  280 ,  328  engage respective sidewalls  108 ,  110  at about ¾″ from the wheel flange and apply a pressure of about 150-265.10 lbf/sq. in. It should be noted, however, that other pressures may be used without departing from the scope of the disclosure. This gap is sufficiently large to allow trapped air in between the bead  112  and bead seat  114  to escape through the gap and displace any debris between the bead and the bead seat as a result of the rotational forces acting on the debris. But the gap is sufficiently small to inhibit significant deflation of the tire  102 . After any debris is displaced, and the bead  112  again contacts the bead seat  114 . This contact occurs after the respective portion of the sidewall is no longer in contact with the bead seating rollers  280 ,  328 . 
         [0055]    In this exemplary process, the wheel assembly  100  is rotated between approximately 200-1000 revolutions per minute for between approximately one to ten seconds. It should be noted, however, that other rates of rotation may be used and other durations of time may be utilized without departing from the scope of the disclosure. 
         [0056]    Referring to  FIGS. 5 and 13 , at step  410 , one or both of the bead seating assemblies  270 ,  320  are repositioned to discontinue contact between the one or both bead seating rollers  280 ,  328  and a corresponding sidewall  108 ,  110  of the tire  102 . In sum, at the end of step  410 , both bead seating assemblies  270 ,  320  no longer contact the tire  102 . 
         [0057]    Referring to  FIGS. 5 and 14 , at step  412 , the drive roller assemblies  230 A,  230 B,  230 C,  230 D are disengaged. This includes first stopping the rotation of the rollers  232 , followed by repositioning of the rollers to no longer contact any portion of the tire  102 . 
         [0058]    At step  414 , the hold-down assembly  250  is raised from the working position (see  FIG. 7 ) to the retracted position (see  FIG. 4 ) to so that the hold-down rollers  252  no longer contact the top circumferential edge between the sidewall  108  and the tread section  106 . 
         [0059]    At step  416 , the studs  208  of the conveyor  202  are raised to elevate the wheel assembly  100  above the rollers  222 . Thereafter, the conveyor  202  removes the wheel assembly  100  from the working area  204  and conveys it along the conveyor. At this time, while the wheel assembly is positioned on the conveyor outside of the working area, a worker may exchange one wheel assembly  100  having completed the process for another wheel assembly needing to undergo the process. Thereafter, the foregoing process is repeated using steps  400 - 416 .
