DETAILED DESCRIPTION 009] The present subject matter relates to a center-aligning sysem o center align a ire building component on a carcass building drum.
0010] Tire building components comprise an inner liner, sidewalls, fillers, first ply, second ply, bead rings, and tread all of which are used to make a green tire by assembling them on a surface of a cylindrcally shaped, rotatable carcass building drum. The carcas building drum may be radially collapsed and expanded without damage or distortion to the tire building components formed on the carcass building drum which permits widthwise adjustment of the carcass building drum without interrupting the smooth continuity of the tire building surface. The carcass building drum expands in order to increase the diameter of the drum surface, to provide shoulders at both ends of the carcass building drum and collapses so as to reduce the carcas building drum diameter to enable the finished tire to be removed from the carcas building drum or ubsequent vulcanizing operations hereafter
[0011] Conventionally, in a tire building machine, configured is a top roll assembly, compriing a pressing roller. As the tire building components are placed on the rotating carcass building drum, the pressing roller is employed to simultaneously pres the superposed layers of the tire building components on the rotating carcass building drum, so that the tire building components stick together to form a uniform carcass. 0012] During application of a tire building component on the carcass building drum, he tre building component may deviate from the center of the carcass building drum, shifting the tire building component from he desired ateral positon relative to the center of the carcass building drum, causing the off-center application of the tire building component on the carcass building drum. Deviation of the tire building component from the central posiion of the carcass building drum may happen due to numerous reasons such as friction, speed variation of an applicator or the carcass building drum during application, and material shrinkage. Also, the effect of deviation cannot be determined manually, as it may not be possible for an operator to detect the displacement of the te building components durng asembling them on the carcas building drum.
[0013] Since the application of the tire building components on the carcass building drum, each ime, depends on the operator having to manually align the tre building components on the carcass building drum, he operations may be prone to such of-center application as described above, resulting in production of defective tires. [0014] The present subject matter provides a center-aligning system to center-align tire building components on a carcass building drum The center-aligning sysem comprises a top roll assembly and wherein, the top roll assembly comprises a presng roller When a tire building component is applied on the carcass building drum, the pressing roller of the top roll assembly, is employed to press the tire building component on the surface of the carcass building drum through a linear vertical movement of the top roll assembly. A main plate is attached to the top roll assembly to otatably suppor he presng roller agains he rotatable carcas building drum The
main plate has a fit side plate at a first end of he main plate and a second side plate at a second end of the main plate, respectively. At the fir end of the main plate, the pressing roller s rotatably fixed to the first side plate. At the second end of the main plate, he pressng roller is coupled to the second side plate and i movable in a vertcal direction with respect to the carcas building drum.
0015] The center-aligning system further comprises a linear module, which is coupled to the top roll asembly, at the second end of the main plate. The linear module adjusts an alignment of the pressng roller with respect to the carcass building drum through the vertical movement of the pressng roller at the second end of the main plate. The center-aligning system also comprises a self-align bearing provided at the first end of the main plate to allow angular deflection of the pressng roller at the first end with respect o the vertcal movement of he presng roller at he second end of he main plate.
[0016] The present invention provides techniques to apply tire building components onto the center of the carcass building drum. Alignment of the tire building components onto the center of the carcass building drum provides for overcoming the above-mentioned defects and results in manufacturing of non-defective tires with enhanced lifetime. Furthermore, the center-aligning system described herein requires substantially low attention of the operator and can be operated with minimum manual intervention. Other objects and advantages of the invention will be apparent from he following description, the accompanying drawings, and the appended claims. [0017] The above and other features, aspects and advantages of the subject matter will be better explained with regard to the following description and accompanying figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter along with examples described herein and, should not be construed as a limitation to the present subject matter. It i thus understood that various arrangements may be devised that, although not explicitly described or shown herein, embody the prnciples of the present disclosure. Moreover, all satements herein
reciting prnciples aspects and examples thereof, are intended to encompass equivalents thereof. Further, for the sake of implicity, and without limitation, the same numbers are used throughout the drawings to reference like features and components. [0018] Fig. 1 illustrates a block diagram of a center-aligning system 100 for a tire building component, in accordance wih an implementation of the present subject matter. The center-aligning system 100 is implemented in a tire building machine (not illustrated). The center-aligning system 100 comprises a carcass building drum 102, wherein the carcass building drum 102 is rotatable and is operable for shaping a green tire to desired dimensions, namely, the developed width of the green tire, as well as the diameter and width of the finished tire. The carcass building drum 102 may be a conventional tire building drum, or other similar drums which are all well known in the art, for providing a desired shape to the green tire. In an example implementation of the present subject matter, the carcass building drum 102 may comprise a circumferential ring of drum segments defining a cylindrcal surface on which a tire building component may be laid up, wherein each of said segments may move radially and be guided durng such radial movement o as o expand or contract the cylindrical
urface.
0019] For the sake of brevity, the present invention has been explained with respect to the single tire building component, however, the teaching of the invention may also apply to more than one tire building components that may be laid up on the carcass building drum 102 for making of the green tire. Further, the carcass building drum 102 may also comprise an expansible ring at each end of the drum and means for expanding the rings to lock the components against surrounding beads. The drum segments of the carcass building drum 102 may have means to expand, in order to radially increase a diameter of the cylindrical surface of the carcass building drum 102, to provide shoulders at both ends of he carcass building drum 102, and to collapse so as to reduce a diameter of he carcas building drum 102 to enable the nished green tire to be
emoved from he carcass building drum 102 or ubsequent vulcanizing operations
hereafter.
0020] In another mplementation of the present subject matter, the center-aligning
sysem 100 comprises a top roll assembly 104, wherein the top roll assembly 104 further comprses a pressing roller 106. The top roll assembly 104 s operable for pressing the tre building component on the surface of the carcass building drum 102
through pressing roller 106 which is configured to the top oll asembly 104. In an implementation of the present subject matter, the pressing roller is to enable lateral alignment of the tre building component that is being applied to carcass building drum 102 with respect to the center of the carcass building drum 102. The configuration and operation of the top roll asembly 104 has been elaborated wih espect o Fig. 2 n
subsequent paragraphs.
[0021] The center-aligning sysem 100, in an implementation, to enable the movement of the pressing roller 106 with respect to carcass building drum 102, to center-align the tire building component on the carcass building drum 102, may comprise a programmable logic control (PLC) 108. In an example, the PLC 108 may be provided with a sofware component such as a PLC application which may have a configuration file to define the objects and logic of movement of the pressing roller 106 with respect
to the carcass building drum 102, by asigning input/outputs (IO), and logic based on the system as define via a configuration tool. In an example implementation, the components of the PLC 108 may include, IO controllers, power supply, input module, output module, processor (CPU), rack or mounting assembly, a programming unit (software), for example, for unning the PLC 108 without interrupting tire building operation. The IO controllers of the PLC 108 may be jointly operative for managing
the signals and logic required to vertically move the pressing roller 106. [0022] In an embodiment, the center-aligning system 100 may comprise a human machine interface (HMI) 110, which is coupled with the PLC 108, as shown in Fig. 1. The HM 110 i o allow a user o feed inputs o the PLC 108 to control he movement
of the pressing roller 106. The inputs, n an example, may be position values, each indicative of a position of he pressing roller 106 with respect o the carcass building drum 102. The movement of the pressing roller 106 is controlled in tandem with the positon values set n the HMI 110 and in turn provided to the PLC 108 through an
interface of the HMI 110 electrically through a cable or other similar means.
0023] In an example implementation, the HMI 110 may comprise a display (not illustrated), a multdimensional input device (not illustrated), a computer communicating (not lustrated) wih a network. The HMI 110, in response to an input provided to the multidimensional input device, may allow an operator viewing the display and operating the multidimensional input device to feed the position values in the HMI 110 with the help of multidimensional input device. The computer may further execute interface programs on the PLC 108 in response to the position values set by
the operator in the HMI 110. The PLC 108, in accordance to the position values fed through the HMI 110, may align the pressing roller 106 vertically, according to the position values, to stop the offcenter application of he te building component on the carcass building drum 102.
[0024] In one of the example embodiment of the present subject matter, the display may be a cathode ray tube (CRT), LED, LCD or any other type of display. Such display types are well known in the art. The multidimensional input device may be a conventional keyboard and mouse, or a space ball, or other similar devices which all are well known in the art for providing multi-dimensional input for the operator. [0025] In an implementation, a lnear module 112 which is mounted on the top roll assembly 104 is configured with the PLC 108, o control the vertical movement of the presng oller 106. The linear module 112 to align the vertical movement of the pressing roller 106 wih respect to the carcass building drum 102 to eliminate the off-centre application of the tire building component onto the carcass drum 102, in the green tire building machine during application of the tire building component on the
surace of he carcas building drum 102. The lnear module 112 comprses a sepper
motor 114 and a linear actuator 116, wherein the linear actuator 116 may be coupled to the stepper motor 114. In another mplementation, the stepper motor 114 rotates in a stepwise rotatory motion and the linear actuator 116, coupled to the stepper motor 114, translates the stepwise rotatory motion of the stepper motor 114 into a linear motion. The configuration and operation of the linear module 112 has been elaborated with respect to Fig. 4 in subsequent paragraphs.
[0026] In operation, when the tire building component is applied on the carcass building drum 102, the operator may observe the position of the tire building component with respect to the center of he carcass building drum 102. In an example, the reference of the central position on the carcass building drum 102 may constantly be observed through a laser beam spot focusing on the carcas building drum 102. By using the reference to the central position, the operator may input he posiion values data in the HMI 110 which indicative of a desired central position on the carcass building drum 102. The pressing roller 106, may provide inward and outward push by
the vertical movement of the pressing roller 106 for correcting the lateral alignment of the tire building component according the position values set in the HM 110 by the operator. The structural elements that cause the aligning movement of he presng
roller 106 is presented in subsequent paragraphs.
[0027] In an example implementation of he present subject matter, the center-aligning system 100 may have a sensor (not illustrated) communicatively coupled to the PLC 108, wherein the sensor is to measure the position of the tire building component, just prior to application of the tire building component on the carcass building drum 102. In another example implementation, based on the position of the tire building component, determined by the sensor, the PLC 108 may give command to the linear module 114 to actuate the pressing roller 106 position vertically or pivotally, in accordance with the posion values set in the HMI 110, to correctly align the incoming tire building components hat being applied onto the carcas building drum 102.
[0028] As will be understood, each of the tire building component such as the first
ply, second ply, bead rings, and tread may be in the form of strps or layers and are
applied sequentially one on top of the other on the carcass building drum 102. The
sensor may be configured to sense the position of each of the tire building component
individually, so that each component may be applied on the carcass building drum 102
in a center-aligned manner, i.e., the center of the strips or layers may be aligned with
the center of the carcass building drum 102 by the linear module 112 which is
controlled by the PLC 108, in such a way that the tre building component is aligned
and pressed by the pressing roller 106, to the positions on the carcass building drum
102, where the poson value i et n the HM110 by the operator and fed to the PLC
108.
0029] It s to be understood that the sensor may comprise means to receive power for
its operation, for example, the sensor may comprie a positive pin and a negative pin
for receiving power supply; and a ground pin. For the sake of brevity, such pins of the
sensor and other similar components that will be readily understood by one skilled in
the art have not been discused herein. In an mplementation, the sensor may be a
proximity sensor, which has been suitably calibrated to sense a position of the tire
building component with respect to the carcas building drum 102. n other examples,
the sensor may be an optical sensor as well.
[0030] The center-aligning system 100, may also comprise additional components, actuation of which facilitates rolling of the carcass building drum 102. Accordingly, in an example implementation, the rollers of the carcass building drum 102, may be asociated with a rotating mechanism and associated components. Such concepts that will be readily undersood by one skiled in the art have not been explained herein for the sake of brevity.
0031] Fig. 2 depicts the top roll assembly 104 in greater detail, according to an implementation of the present subject matter. As discussed above, the top roll assembly 104 compres he presng roller 106, wherein the presng roller 106 is to pres he
tire building component on the surface of the carcass building drum 102 through the vertical movement of the top roll assembly 104. The pressing roller 106 is placed in a housng (not illusrated), wherein, during any movement of the pressing roller 106 the housing remains n a fixed positon and only pressing roller 106 may have a rotary motion. The housing may comprise, a main plate 202 to rotatably support he pressing
roller 106, wherein, the main plate 202 has a first side plate 208 at a first end 204 of the main plate 202, and a second side plate 210 at a second end 206 of the main plate 202, respectively. The pressng roller 106 may comprise a central rod 220 surrounded by the presing roller 106 substantially coaxially, wherein the pressng roller 106 is capable of rotating relative to the central rod 220 while being axially secured to the central rod 220. In an example implementation, a rotatable surface of the pressng roller 106 may be of a rubber-like material or any other material that is uitable for rotatably gripping the surface of the rotatable carcass building drum 102 firmly, while presng and aligning the tire building component on the carcass building drum 102.
[0032] In an implementation, at the firs end 204 of the main plate 202, the pressing roller 106 may be rotatably fixed to the first ide plate 208, and wherein, at the second end 206, the pressing roller 106 may be vertically movable with respect to the carcass building drum 102. The vertical movement of the pressing roller 106 may be understood based on the depiction presented in Fig. 2 that uses a dotted line to depict tilting of the pressing roller 106. In an example, the pressing roller 106 tilts so that only one end of the central rod 220, at the second end 206, experiences up or down movement and at the frst end 204 where the central rod 220 is coupled to the first side plate 208, experiences no linear vertical movement. Tilting the pressing roller 106 may introduce a gradient of tension between the top and bottom edges of the tire building component which may be used to actively steer or adjust the tire building component at a predetermined central position of the carcass building drum 102. In one embodiment, the pressing roller 106 is tiltable and is biased at the second end 206 on a pivot axi elative to the carcas building drum 102, by the lnear module 112.
[0033] In the top roll assembly 104, in an implementation, a bracket assembly 300-1 may be provided at the second end 206 of the main plate 202, and wherein the bracket asembly 300-1 may be coupled to the second side plate 210. The pressing roller 106 is xed in the bracket assembly 300-1, wherein the actuation of the pressing roller 106 at the second end 206 is provided by the bracket assembly 300-1 through the linear module 112. The bracket assembly 300-1 comprises a hinge 212 that is attached to the
linear module 112 at lower font end of the linear module 112. The hinge 212 is to suppor the actuation of pressing roller 106 that is attached to the bracket assembly 300-1. The bracket assembly 300-1 furher comprises a bush-rail arrangement 214, wherein the bush-rail arrangement 214 is to guide the vertical movement of the pressing roller 106 with respect to the pressing roller 106. The bush-rail arrangement 214 comprises a guide rail 216 and a bush 218, wherein the bush 218, which may be inserted
into a supporing body for a tensioning guide rail 216. The bush-rail arrangement 214
is to support he thrust of the pressing roller 106 in the vertical direction with respect
to the carcass building drum 102 at the second end 206 of the main plate 202. [0034] In the top roll assembly 104, in another implementation, a self-align bearing 300-2 may be provided at the first end 204 of he main plate 202, and wherein the self-align bearing 300-2 may be coupled to the first sde plate 208. The pressing roller 106 may be attached to the self-align bearing 300-2 through the central rod 220. The self-align bearing 300-2 provided at the first end 204 of the main plate 202 may allow tilting of the pressing roller 106 at the second end 206 by providing an angular flexibility,
through the angular deflection of the pressing roller 106 at the first end 204.
0035] In an embodiment, position of the pressing roller 106 may also be set separately, for each of he tire building components by changing the position values in the HMI 110. Using the HMI 110, position values may also be set o adjust he inclination of the pressing roller 106 for different tire building components, such as inner liner, first ply,
second ply etc. In an example, the poson value ettng provided by he operator
hrough the HMI 110 may obtain an accuracy of 1 millimeter in tiltng the presng roller 106 at the second end 206 and for each tire building component. [0036] In yet another implementation of the present subject matter, the pressing roller 106 may be adapted to be rotated by a rotating means (not iustrated) and may press the tire building component against the cylindrical wall of the outer surface of the carcass building drum 102, with progressive change of pressure. The plurality of tire building component is applied on the carcass building drum 102 wherein the applying step of diferent tire building components may be different. For example, application of strips is initiated just before the termination of the wrapping of he cord or wire-reinforced ply about the carcass building drum 102.
[0037] Fig. 3a depicts an exploded view of he bracket assembly 300-1. At the second end 206 of the main plate 202, one end of the central rod 220 may engage with the bracket assembly 300-1 through a groove 302 provided on the bracket assembly 300-
1. The bracket assembly 300-1, affixed to the underside of he lnear module 112 may
act as a vertical arm for the presng roller 106, which carries the pressing roller 106
during the vertical movement of the pressing roller with the support of the bush-rail
arrangement 214. The bush-rail arrangement 214 provided in the bracket asembly
300-1, actuate to provide vertical movement o the pressing roller 106.
[0038] Fig. 3b depicts an exploded view of the self-align bearing 300-2. At the first end 204 of the main plate 202, another end of the central rod 220 may engage with the self-align bearing 300-2 through a groove 304 provided on the self-align bearing 300-
2. The pressing roller 106 remains in a fxed state at he frst end 204 of the main plate
202, and the self-align bearing 300-2 is only to allow the angular deflection of he
pressing roller 106 at the frst end 204 of the main plate 202 with respect to the tilting
of the pressing roller 106 through vertical movement of the pressing roller 106 at the
econd end 206 of the main plate 202. The self-align bearing 300-2 may be any known self-align bearing which may comprise, for example, a relatively fixed foundation, a bearing element, and at eas a pair of uts exibly connecting said bearing element
with said oundation, said connecting sturts being arranged so as to form a four-bar inkage with said foundation and said bearing element. The self-align bearing 300-2 of he present invention may align itself wih a minimum of binding force exerted on the first side plate 208 by the movement of the presing roller 106, which may withsand high thrust load of the pressing roller 106, exerted by the carcass building drum 102 durng the pressing and alignment of the tie building component on the carcass building drum 102.
[0039] Fig. 4 depicts the linear module 112 in greater detail The linear module 112 of the center-aligning sysem may comprise a stepper motor 114, wherein the stepper motor 114 rotates in a stepwise rotatory motion. A linear actuator 116, coupled to the stepper motor 114, transate the stepwise rotatory motion of the sepper motor 114 into a linear motion in order to actuate the presing roller 106 at the second end 206 of the main plate 202 in the vertical movement with respect to the carcass building drum 102. [0040] As explained with respect to the Fig. 1 and Fig.2, in an implementation, the linear module 112 operates according to the posiion values set in the HMI 110. The operator ets the position values in the HMI 110 through an interface of the HMI 110. The HMI 110 further communicates to PLC 108, wherein the PLC 108 may give a signal to the linear module 112 to perform the vertcal movement of the pressing roller 106 due to which the presing roller 106, which i attached to linear module 112, tilts at the second end 206 of the main plate 202. Tiltng of the pressing roller 106 with respect to the carcass building drum 102 helps in steering tire building component so as to bring the tire building component on the center of the carcass building drum 102, and ensuring on-center application of he te building component on urface of he carcass building drum 102.
0041] In an example implementation of the present subject matter, the signal from the sensor may also cause the PLC 108 to send command to the linear module 112 for the vertical movement of the pressing roller 106 in order to correct an error, in centering of the tie building component on the carcas building drum 102, so that the tie
building component may be applied on the center of the carcass building drum 102. In another example implementation of the present subject matter, the stepper motor 114 coupled to the linear module 112 to adjust he position of the pressing roller 106 may be controlled by the commands emanating from PLC 108. The PLC 108, n accordance with the position values settings of the HMI 110, to center-align the pressing roller 106, may cause the sepper motor 114 to provide force to the linear actuator 116 to actuate the pressing roller 106 vertically with respect to the carcass building drum 106. In an example embodiment of the present subject matter, the stepper motor 114 may be any conventional epper motor having displaceable excitng windings which is well known
in the art.
[0042] The PLC 108 controls the linear module 112 and the stepper motor 114 to achieve synchronization in their movement with respect o the position values set in the HMI 110, to ensure that the tire building component i applied accurately on the center of he carcass building drum 102. Centre-aligning of the tire building component enhances the quality of the manufactured tire. Furthermore, the center-aligning system 100 described herein is automated, thereby having minimal human intervention,
educing the cost and susceptibility to error asociated with human labor. [0043] Therefore, the present subject matter, align the pressing roller 106 over the carcass building drum 102 in order to stop the deviation of the tire building component while applying it on the carcass building drum 106. Furher, by using the PLC controlled stepper motor 114, it may be ensured that, the tire building component is applied only at the predefined postion on the carcass building drum 106, even if the operator is not there, by alignment of he presng roller 106 according the set postion values in the HMI 110.
0044] Accordingly, the implementations of the present subject matter ensure the
[0045] Although the subject matter has been described in consderable detail with reference to certain examples and implementations thereof, other implementations are possible. As such, the present disclosure should not be considered limited to the description of he preferred examples and implementations contained therein.
