Description

Background Art

[0001] The present invention relates to a tire manufacturing plant and a method for manufacturing a cord-reinforced tire component, such as a body ply or a breaker ply, for a green or unvulcanized tire.

[0002] FIG. 1 shows a known tire manufacturing plant including a tire manufacturing apparatus and two creels that alternately supply cords in a cord supply direction to the tire manufacturing apparatus. The creels are movable in a lateral direction perpendicular to the cord supply direction between an operating position in line with the tire manufacturing apparatus and a standby position on the side of the creel in the operating position. In FIG. 1, also refer to the dashed square representing the standby position of the currently operating creel.

Summary of the Invention

[0003] In response to the increasing market demand for tire components in which a large number of cords are embedded, the number of creel bobbins held by each creel has been increasing. A drawback of conventional tire manufacturing plants is that the creels significantly affect the installation area of the entire facility. In particular, in a conventional configuration in which the creels are arranged in-line, when the size of the creels increases, the overall length of the facility increases significantly. In other words, conventional tire manufacturing plants occupy a large floor area.

[0004] An object of the present invention is to provide a tire manufacturing plant and a method for manufacturing a cord-reinforced tire component that can be designed more compactly.

[0005] According to a first aspect, the present invention provides a tire manufacturing plant comprising a tire manufacturing apparatus for manufacturing cord-reinforced tire components and a first creel for supplying cords to the tire manufacturing apparatus. The tire manufacturing plant further comprises a first deflection device for deflecting a first group of cords, the first deflection device comprising a deflection member for receiving the first group of cords in the receiving direction and deflecting the first group of cords from the receiving direction in a deflection direction about a deflection axis, the first deflection device further comprising an input cord collector for guiding the first group of cords toward the deflection member in the receiving direction, and an output cord collector for guiding the first group of cords toward a deflection direction away from the deflection member, the input cord collector for each cord of the first group of cords at different input guidance positions among a plurality of input guidance positions To pass the code through the code collector, a plurality of input induction positions are defined that are spaced apart from each other by at least a vector component in the separation direction parallel to the deflection axis, and the output code collector is an induction position spaced apart from each other by at least a vector component in the separation direction for passing each code of the first code group through output code collectors located at different output induction positions among the plurality of output induction positions, and the tire manufacturing apparatus includes a code alignment device for receiving the first code group from the first deflection device, and the code alignment device is configured to arrange the code in an alignment plane that is orthogonal or perpendicular to the deflection axis.

[0006] In other words, the deflection axis can be positioned perpendicular or perpendicular to the alignment plane. The cords of the first cord group downstream of the first deflection device are inclined from an output focusing plane parallel to the deflection axis toward the alignment plane as they exit the first deflection device. The output cord collector of the first deflection device can ensure that the cords of the first cord group between the deflection member and the output cord collector are guided in the deflection direction around the deflection axis, despite the inclination of the first cord group downstream of the first deflection device.

[0007] Furthermore, by placing a first deflection device between the tire manufacturing equipment and the creels in a tire manufacturing plant, the tire manufacturing plant does not necessarily need to arrange the creels in a straight line with the tire manufacturing equipment. In fact, by providing the first deflection device, the creels can be positioned at any angle, including acute and right angles, relative to the tire manufacturing equipment, enabling entirely new layout options. In this way, the layout design becomes more flexible and can be adapted to best suit the available space in the factory. In particular, the overall length of the tire manufacturing plant can be shortened, more creels can be arranged parallel to each other without increasing the width of the tire manufacturing plant, or the entire tire manufacturing plant can be designed to be more compact.

[0008] In one embodiment, the first deflection device further includes an input code collector that guides a first group of codes toward a deflection member in the receiving direction, the input code collector defines a plurality of input guidance positions spaced apart from each other and having at least a vector component in the separation direction, and each code of the first group of codes is passed through the input code collector at a different input guidance position among the plurality of input guidance positions. Regardless of the relative orientation of the codes as they approach the input code collector or as they exit the output code collector, the codes can be deflected from the receiving direction to the deflection direction around the deflection axis while maintaining an orderly arrangement of the codes. In particular, the codes can be reliably deflected between the input code collector and the output code collector while preventing the codes from becoming entangled or twisted during deflection.

[0009] Preferably, each input induction position of the plurality of input induction positions is at a unique level along the separation direction relative to the other input induction positions of the plurality of input induction positions.

[0010] Furthermore, or alternatively, each output induction position of the multiple output induction positions is at a unique level along the separation direction relative to the other output induction positions of the multiple output induction positions.

[0011] In a second, unclaimed aspect, the present invention provides a first deflection device for deflecting a first group of codes. The first deflection device comprises a deflection member for receiving the first group of codes in an incoming direction and deflecting the first group of codes from the incoming direction in a deflection direction about a deflection axis, the first deflection device further comprises an input code collector for guiding the first group of codes to the deflection member in an input focusing plane parallel to the deflection axis in the incoming direction, and an output code collector for guiding the first group of codes away from the deflection member in a deflection direction in an output focusing plane parallel to the deflection axis.

[0012] A first deflection device according to a second aspect of the present invention has the same technical advantages as a first deflection device in an embodiment of a tire manufacturing plant according to a first aspect of the present invention, which includes an input code collector.

[0013] The following embodiments can be applied to the first or second embodiment of the present invention.

[0014] In one embodiment, multiple input induction positions are spaced apart by a first separation distance in the separation direction, and multiple output induction positions are spaced apart by a second separation distance, the same as the first separation distance, in the separation direction. In other words, the cords are kept parallel or substantially parallel while the first group of cords is deflected around the deflection axis. This prevents the cords from becoming entangled or twisted during deflection.

[0015] In another embodiment, each input guide position of a plurality of input guide positions is positioned at the same level as each output guide position of a plurality of output guide positions in the separation direction. This causes each code to be deflected in a deflection plane perpendicular to the deflection axis. This prevents the code from twisting about its own longitudinal axis.

[0016] In another embodiment, the input code collector and the output code collector are configured to guide the codes of the first code group toward the deflection member in directions parallel to each other, or toward the deflection member outward. In other words, the distance between the codes can be kept constant while the first code group is deflected around the deflection axis. Thus, it is possible to prevent the codes from becoming entangled or twisted during deflection.

[0017] In a further embodiment, the input code collector comprises an input collector body and a plurality of input focusing channels extending through the input collector body in the receiving direction, where each code of the first code group is passed in the receiving direction to a different first focusing channel among the plurality of input focusing channels. On the other hand, the output code collector comprises an output collector body and a plurality of output focusing channels extending through the output collector body in the deflection direction, where each code of the first code group is passed in the deflection direction to a different second focusing channel among the plurality of output focusing channels. Since each code can be passed individually to the respective focusing channel of each code collector, entanglement or twisting of the codes is prevented in each code collector.

[0018] In another embodiment, the first deflection device is configured to deflect the first group of cords by a deflection angle of at least 20 degrees, preferably at least 40 degrees, and most preferably at least 80 degrees, between the receiving direction and the deflection direction. As mentioned above, such angles enable entirely new layout options in tire manufacturing plants.

[0019] In another embodiment, which can be applied independently of a tire manufacturing plant, the first deflection device comprises a holder for holding a deflection member, the deflection member being movable relative to the holder in a tension direction perpendicular to the deflection axis. Thus, the deflection member can be moved back and forth manually or automatically so as to be in contact with or not in contact with the cords. By keeping the deflection member away from the cords, it is possible to make it easier to pass the cords through their respective cord collectors when preparing or initially inserting the cords. In particular, the cords may pass loosely through the area later occupied by the deflection member. Once all the cords are inserted, the deflection member can be returned to its original position to apply tension to the cords. Since each cord is passed through its respective cord collector in its own unique position, the movement, contact, and / or tension between the deflection member and the cords can automatically untangle or cross the cords.

[0020] Preferably, the input code collector is configured to receive a first group of codes on an input focusing plane parallel to the receiving direction and the deflection axis, and the output code collector is configured to receive a second group of codes on an output focusing plane parallel to the deflection direction and the deflection axis, and the deflection member is movable in the tension direction between an operating position in contact with the input focusing plane / or output focusing plane and a retracted position where the deflection member is spaced away from the input focusing plane or output focusing plane. Thus, in the operating position, the deflection member can be positioned to be in contact with the codes on each focusing plane, thereby ensuring smooth, reliable, or controlled deflection of the codes around the deflection member.

[0021] In another embodiment, the deflection member is a deflection roller that is rotatable about a deflection axis. This deflection roller can guide or feed the cord along the circumference with less friction than a fixed deflection member.

[0022] In another embodiment, the first creel comprises a frame for holding a creel bobbin, the frame of the first creel extending into a first creel plane that extends at a creel offset angle of at least 20 degrees, preferably at least 40 degrees, and most preferably at least 80 degrees with respect to the deflection direction. As described above, the first deflection device enables a whole new range of layouts for tire manufacturing plants, including layouts featuring the creel offset angles described above.

[0023] In another embodiment, the first creel is configured to supply the first group of cords in multiple creel output directions and converge toward the first deflection device. Thus, the cords of the first group of cords upstream of the first deflection device approach and / or enter the first deflection device in various directions. The input cord collector of the first deflection device can ensure that, regardless of the various directions of the cords upstream of the first deflection device, the cords of the first group of cords between the input cord collector and the deflection member are guided in the deflection direction at the input cord collector.

[0024] In another embodiment, the tire manufacturing plant comprises one or more further creels similar to the first creel and one or more additional deflection devices similar to the first deflection device, each additional deflection device configured to receive and deflect further code sets from each of the further creels. The one or more further creels can be positioned in the same orientation as the first creel relative to the tire manufacturing plant, thereby enabling entirely new layouts for the tire manufacturing plant. These new layouts can be the subject of one or more divisional applications, without being limited by the deflection devices.

[0025] Preferably, the first creel comprises a frame for holding a creel bobbin, the frame of the first creel extending in the first creel plane, and one or more further creels comprises a second creel comprising a frame for holding a creel bobbin, the frame of the second creel extending in a second creel plane parallel or substantially parallel to the first creel plane. In other words, the first and second creels can be arranged at a creel angle with respect to the deflection direction, but they can also be arranged parallel to each other.

[0026] More preferably, the first and second creel surfaces are spaced less than 100 centimeters, preferably less than 80 centimeters, and most preferably less than 60 centimeters, in the lateral direction perpendicular to the first creel surface. In conventional layouts of known tire manufacturing plants according to the prior art, space is required around each creel to access and service or replenish each creel. However, the tire manufacturing plant according to the present invention can feature an entirely new range of layouts, in some of these layouts, the spacing between creels may be narrow or nonexistent. Within the range defined above, the space between creels may be insufficient for workers to enter. By narrowing the spacing between creels, a more compact tire manufacturing plant can be realized.

[0027] In a further embodiment, this can also be applied independently to a group of creels, where at least one of the first and second creels is movable relative to the other of the first and second creels in an exchange direction parallel to the first creel surface. Thus, instead of moving the creels laterally as in known tire manufacturing plants of the prior art, the creels of the present invention can be moved in an exchange direction parallel to the first creel surface, thereby allowing one creel to be retracted relative to the other, facilitating access, maintenance, and / or replenishment of the retracted creel. In such a retractable configuration, lateral spacing between creels is not required, or is minimal.

[0028] In a further embodiment, this can also be applied independently to the creel group, but one or more additional creels include a third creel having a frame for holding creel bobbins, and the frame of the third creel extends in a third creel plane parallel or substantially parallel to the first creel plane and the second creel plane. The second creel is disposed between the first creel and the third creel in the lateral direction, and in an exchange direction parallel to the first creel plane, the second creel is movable between a supply position flush with the first creel and the third creel in the exchange direction and an exchange position where the second creel is at least partially retracted with respect to the first creel and the third creel. Similar to the above-described embodiment, in this embodiment, it is possible to retract the second creel in the exchange direction from between the first creel and the third creel, thereby eliminating the need for the lateral spacing between each creel.

[0029] Alternatively, at least one of the first creel and the second creel is movable relative to the other of the first creel and the second creel in an exchange direction orthogonal or perpendicular to the first creel plane. Since a deflector device is provided between the creel and the tire manufacturing apparatus, a plurality of creels can be arranged side by side in a direction orthogonal or perpendicular to the tire manufacturing apparatus. Further, the creels are movable relative to each other in the exchange direction, so that, as long as an access space for maintenance, servicing, and / or replenishment is ensured, no lateral spacing or almost no lateral spacing is provided, and they can be arranged directly or almost directly adjacent to each other in the exchange direction, for example. <00,00091>

[0030] <000009,In a further embodiment, the first creel comprises a frame for holding creel bobbins, the frame of the first creel extends within the first creel plane, and one or more additional creels comprise a fourth creel having a frame for holding creel bobbins, the frame of the fourth creel extending within a fourth creel plane that is orthogonal or perpendicular to the first creel plane. Thus, not all creels necessarily extend in the same direction. Layouts are envisioned where the creels or groups of creels extend in different directions, thereby allowing the cords from different creels to be alternately connected to the tire manufacturing apparatus during servicing or replenishment of other creels.

[0031] In yet another embodiment, one or more additional creels are composed of a first group of creels and a second group of creels located on opposite sides of a central plane. Thus, the cords of one group of creels can be easily connected to the tire manufacturing apparatus from one side of the central plane during servicing and / or replenishment of the other group of creels.

[0032] Preferably, the tire manufacturing apparatus comprises a cord alignment device that receives a group of cords from the first deflection device and one or more further deflection devices, the cord alignment device being configured to align the group of cords in a direction parallel to each other in the cord supply direction, and the central plane being parallel or substantially parallel to the cord supply direction in the cord alignment device. By aligning the central plane in the cord supply direction, the cords can be supplied to the tire manufacturing apparatus from the first group of creels or the second group of creels in the same or substantially the same manner.

[0033] In another embodiment, the tire manufacturing plant further includes an automated replacement tool for automatically replacing the creels. By automatically removing creels from a group of creels in the tire manufacturing plant, the preparation, maintenance, and replenishment of creels can be performed remotely. This reduces the space required for the tire manufacturing plant itself, allowing for a more compact design. This is particularly useful when the creels are relatively small, for example, when multiple relatively small or short creels are arranged in a line with respect to the direction of deflection at a creel angle. These small creels are easily handled and moved, for example, using automated guided vehicles (AGVs) or autonomous mobile robots (AMRs).

[0034] According to a third aspect, the present invention provides a method for manufacturing a cord-reinforced tire component using a tire manufacturing plant according to any one of the embodiments of the first aspect of the present invention, the method comprising the following steps: The first set of codes is received from the first creel by the first deflection device. The first set of codes is deflected by the first deflection device.

[0035] This method relates to the practical implementation of a tire manufacturing plant according to a first aspect of the present invention and therefore has similar technical advantages, but this will not be repeated below.

[0036] In a preferred embodiment of this method, the codes of the first group are deflected between the acceptance direction and the deflection direction over a deflection angle of at least 20 degrees, preferably at least 40 degrees, and most preferably at least 80 degrees.

[0037] In another embodiment, this method further includes the following steps: Each code in the first code group is passed through the input code collector of the first deflection device in the receiving direction. Each code in the first code group is guided from the input code collector to the output code collector of the first deflection device. Each code in the first code group is passed through the output code collector of the first deflection device and directed in the direction of deflection.

[0038] Preferably, the input code collector is configured to receive a first group of codes on an input focusing plane parallel to the receiving direction and the deflection axis, the output code collector is configured to receive a second group of codes on an output focusing plane parallel to the deflection direction and the deflection axis, the deflection member of the first deflection device is movable in the tension direction between an operating position in contact with the input and output focusing planes and a retracted position where the deflection member is separated from the input and output focusing planes, and the method further includes the following steps: Move the deflection member from the operating position to the retracted position. Move the deflection member from the retracted position to the operating position.

[0039] In another embodiment, the tire manufacturing plant comprises one or more further creels similar to the first creel and one or more additional deflection devices similar to the first deflection device, and the method further includes the following steps: Accepting additional code sets in each of the additional deflection devices of one or more additional deflection devices; and Each deflection device deflects an additional set of codes.

[0040] Preferably, the first creel comprises a frame for holding a creel bobbin, the frame of the first creel extending within the first creel plane, and one or more further creels comprise a second creel including a frame for holding a creel bobbin, the frame of the second creel extending within the second creel plane, and the method comprises the following steps: The first creel and the second creel are positioned such that the planes of the first creel and the planes of the second creel are parallel or substantially parallel.

[0041] More preferably, this method further includes the following steps: At least one of the first and second creels is moved in an exchange direction parallel to the first creel plane relative to the other of the first and second creels.

[0042] In another embodiment, one or more further creels include a third creel which includes a frame for holding a creel bobbin, the frame of the third creel extending in a third creel plane parallel to the first and second creel planes, the second creel being located between the first and third creels in a transverse direction perpendicular to the first creel plane, and this method includes the following steps: The second creel is moved in an exchange direction parallel to the first creel plane, between a supply position in which the second creel is flush with the first and third creels in the exchange direction, and an exchange position in which the second creel is at least partially retracted from the first and third creels in the exchange direction.

[0043] Alternatively, this method includes the following steps: At least one of the first and second creels is moved in an exchange direction perpendicular or perpendicular to the plane of the first creel relative to the other of the first and second creels.

[0044] In another embodiment, the first creel comprises a frame for holding a creel bobbin, the frame of the first creel extending in the first creel plane, and one or more further creels comprises a fourth creel including a frame for holding a creel bobbin, the frame of the fourth creel extending in the fourth creel plane, and this method comprises the following steps: The first and fourth creels are positioned such that the plane of the fourth creel extends perpendicularly or perpendicularly to the plane of the first creel.

[0046] Preferably, this method further includes the following steps: The codes from the first group of creels and the codes from the second group of creels are alternately connected to the tire manufacturing device.

[0047] In another embodiment, the tire manufacturing plant further includes an automated replacement tool for automatically replacing the creel.

[0048] The various aspects and features described and presented herein can be applied individually as far as possible. These individual aspects, in particular those described in the attached dependent claims, may be the subject of a divisional patent application. [Brief explanation of the drawing]

[Figure 10] Figure 10 shows an isometric and top view of yet another tire manufacturing plant according to a sixth exemplary embodiment of the present invention. [Modes for carrying out the invention]

[0050] Figure 2 shows a tire manufacturing line or tire manufacturing plant 1 according to a first embodiment of the present invention. The tire manufacturing plant 1 comprises a tire manufacturing apparatus 4 for manufacturing cord-reinforced tire components (not shown) and a number of creels 21-25 for supplying wire or cord K to the tire manufacturing apparatus 4. In this example, the cord K is a metal cord, particularly a steel cord. The cord-reinforced tire component may be, for example, a body ply or a breaker ply. Such cord-reinforced tire components are used together with other tire components to form a green tire or an unvulcanized tire.

[0051] As shown in Figure 2, the tire manufacturing apparatus 4 includes a cord alignment device 41 that sorts the cords K received from a plurality of creels 21-25 and guides the sorted cords K further into the tire manufacturing apparatus 4 along the cord supply direction F. The tire manufacturing apparatus 4 further includes an extruder 42 that receives the cords K from the cord alignment device 41 along the cord supply direction F and embeds the cords K into an extruder of elastomer material, which in this example is rubber, to form a cord-reinforced tire component.

[0052] As further shown in Figure 2, the multiple creels 21-25 consist of a first creel 21, a second creel 22, a third creel 23, a fourth creel 24, and a fifth creel 25. The fifth creel 25 represents any creel, including a sixth creel that is not assigned a reference number. Within the scope of the concept of the present invention, it will be understood that any number of creels can be combined in different layouts of a tire manufacturing plant. In this example, the multiple creels 21-25 are divided into a first group N1 consisting of creels 21-23 and a second group N2 consisting of creels 24 and 25.

[0053] Of the multiple creels 21-25, only the first creel 21 will be referred to and described in more detail. The first creel 21 is representative of any of the other creels 22-25.

[0054] The first creel 21 comprises a frame 31 for holding multiple creel reels or creel bobbins 32. Each creel bobbin 32 holds or transports a cord K wound multiple times around the creel bobbin 32. The frame 31 of the first creel 21 extends within or defines the first creel surface C1. For the other creels 22-25, corresponding creel surfaces C2-C5 are defined.

[0055] In this example, the frame 31 of the first creel 21 supports or holds the creel bobbins 31 on both sides of the first creel surface C1. Alternatively, the creel may hold the creel bobbins on only one side of each creel surface. In yet another embodiment, multiple creel bobbins may be supported concentrically or coaxially on the same side of each creel surface.

[0056] The code K from multiple creel bobbins 32 is sent to the first creel 21 using guides such as guide tubes (not shown) and discharged from the front end of the first creel 21 as the first code group G1. The code K2 of the first code group G1 is transferred from the first creel 21 to the tire manufacturing apparatus 4 in a manner that will be described in more detail below.

[0057] Similarly, the code K of the second code group G2 comes out of the second creel 22, and the code K of the third code group G3 comes out of the third creel 23. The code K of the first code group G1, the code K of the second code group G2, and the code K of the third code group G3 are assembled and sorted by the code alignment device 41 of the tire manufacturing apparatus 4. The codes in creels 24, 25 of the second creel group N2 are not yet prepared, have not been supplied to the tire manufacturing apparatus 4, and / or been induced.

[0058] As shown in Figure 2, the tire manufacturing plant 1 further includes a plurality of deflection devices 51 to 55 between the creels 21 to 25 and the tire manufacturing apparatus 4, which deflect groups G1 to G3 of code K from the creels 21 to 25 toward the tire manufacturing apparatus 4. In particular, the plurality of deflection devices 51 to 55 include a first deflection device 51 between the first creel 21 and the tire manufacturing apparatus 4, a second deflection device 52 between the second creel 22 and the tire manufacturing apparatus 4, a third deflection device 53 between the third creel 23 and the tire manufacturing apparatus 4, a fourth deflection device 54 between the fourth creel 24 and the tire manufacturing apparatus 4, and a fifth deflection device 55 between the fifth creel 25 and the tire manufacturing apparatus 4. The fifth deflection device 55 represents one of the other deflection devices, such as a sixth deflection device, that have not been assigned a reference number.

[0059] The operating principles of the multiple deflection devices 51-55 will be explained in more detail by referring only to the first deflection device 51. However, it goes without saying that the same principles apply to the other deflection devices 52-55.

[0060] As shown in Figure 6, the first deflection device 51 includes a deflection member 61 that receives the first code group G1 in the receiving direction A and deflects the first code group G1 from the receiving direction A to the deflection direction B around the deflection axis X. The code K is deflected at a deflection angle H1 of at least 20 degrees, preferably at least 40 degrees, and most preferably at least 80 degrees between the receiving direction A and the deflection direction B. In this example, the deflection angle H1 is approximately 90 degrees.

[0061] In this example, the deflection axis X extends vertically or nearly vertically.

[0062] The deflection member 61 has a cylindrical shape and / or a circumferential surface 62. The circumferential surface 62 is concentric with the deflection axis X. The circumferential surface 62 guides the code K of the first code group G1 along an arc or circular cross-section.

[0063] In the embodiment shown in Figure 6, the deflection member 61 is a deflection roller rotatable about a deflection axis X. The deflection member 61 may optionally include one or more circumferential grooves (not shown) for receiving the codes K of the first code group G1. More specifically, the deflection roller may include a plurality of individually or independently rotatable disk sections, each having a circumferential groove for receiving the codes K of the first code group G1.

[0064] As best shown in Figure 6, the first deflection device 51 further comprises a holder 63 for holding a deflection member 61. As shown in Figures 8B and 8C, the deflection member 61 is movable relative to the holder 63 in a tension direction T perpendicular to the deflection axis X. In this example, the holder 63 is formed as a platform or plate-like member. In this example, as shown in Figure 6, the first deflection device 51 comprises a tension drive device 64 for driving the deflection member 61 relative to the holder 63 in the tension direction T.

[0065] As shown in Figure 6, the first deflection device 51 is further provided with a first code collector 71 (input code collector) that guides the codes K of the first code group G1 from the receiving direction A to the deflection member 61, and a second code collector 72 (output code collector) that guides the codes K of the first code group G1 in the deflection direction B away from the deflection member 61. Specifically, the input code collector 71 focuses the codes K from the first creel 21 and arranges or aligns the codes K on a first focusing surface P1 (input focusing surface P1) parallel to the deflection axis X and the receiving direction A. Similarly, the output code collector 72 focuses the codes K from the deflection member 61 and arranges or aligns the codes K on a second focusing surface P2 (output focusing surface P2) parallel to the deflection axis X and the deflection direction B. The input focusing plane P1 and the output focusing plane P2 extend from each other with a deflection angle H1.

[0066] The input code collector 71 and output code collector 72 are detachably mounted on the holder 63, allowing for remote preparation of the code K, particularly at each creel 21. In other words, the code collectors 71 and 72 can be optionally moved in conjunction with the code alignment device 41 to approach each creel 21-25, and the code K can be concentrated at each creel 21-25. Preferably, the code collectors 71 and 72 and the code alignment device 41 are assembled in a block aligned in a line in the code insertion direction, so that each code K can be conveniently inserted into both the code collectors 71 and 72 and the code alignment device 41 in a single operation. The code K can then be clamped, held, and / or secured to the code collectors 71 and 72 and transported in an orderly manner toward the first deflection device 51 together with the code collectors 71 and 72.

[0067] The movement of the deflection member 61 in the tension direction T may occur between an operating position in which the deflection member 61 is in contact with the input focusing plane P1 and the output focusing plane P2, as shown in Figures 6 and 7C, and a retracted position in which the deflection member 61 is separated from the input focusing plane P1 and the output focusing plane P2, as shown in Figures 8A and 8B.

[0068] As shown in Figure 6, the input code collector 71 and the output code collector 72 are adapted, positioned, or configured to guide the codes K of the first code group G1 to or from the deflection member 61, respectively. The input code collector 71 defines a plurality of first guidance positions or input guidance positions 77 distributed throughout the input code collector 71. In this example, the input guidance positions 77 are arranged in a line. The input guidance positions 77 are separated or spaced apart from each other by at least a vector component in a separation direction S parallel to the deflection axis X in order to guide each code K of the first code group G1 to the input code collector 71 at different input guidance positions 77 among the plurality of input guidance positions 77. In particular, each input guidance position 77 of the plurality of input guidance positions 77 is at a unique height along the separation direction S with respect to the other input guidance positions 77 of the plurality of input guidance positions 77. In other words, all input induction positions 77 are distributed on the input code collector 71 such that, in the separation direction S, all input induction positions 77 are at their own specific level, i.e., height.

[0069] Similarly, the output code collector 72 defines a plurality of output induction positions 78. The output induction positions 78 are spaced apart from each other in the separation direction S, with at least a vector component, in order to pass each code K of the first code group G1 through different output induction positions 78 of the plurality of output induction positions 78 to the output code collector 72. In addition, each output induction position 78 of the plurality of output induction positions 78 is at a unique level along the separation direction S with respect to the other output induction positions 78 of the plurality of output induction positions 78.

[0070] Therefore, the cords K are reliably separated from each other in the cord collectors 71 and 72, preventing them from becoming entangled, twisted, or crossing as they pass through the deflection member 6.

[0071] In this example, the input code collector 71 comprises a first collector body or input collector body 73 and a plurality of input focusing channels 75 extending through the input collector body 73 in the receiving direction A. The input focusing channels 75 extend at and / or define each input induction position 77. During the preparation of the first creel 21 for connection to the tire manufacturing apparatus 4 in Figure 2, each code K of the first code group G1 is typically passed through a different first focusing channel 75 of the plurality of first focusing channels or input focusing channels 75 in the receiving direction A. The input focusing channels 75 extend through the input collector body 73 in the receiving direction A and / or extend parallel to the input focusing surface P1.

[0072] Similarly, the output code collector 72 comprises a second collector body or output collector body 74 and a plurality of second focusing channels or output focusing channels 76 extending through the output collector body 74 in the deflection direction B, and each code K of the first code group G1 is passed through a different second focusing channel 76 from the plurality of output focusing channels 76 in the deflection direction B. The output focusing channels 76 extend at and / or define each output induction position 78. The output focusing channels 76 extend through the output collector body 74 in the deflection direction B and / or parallel to the output focusing plane P2.

[0073] As shown in Figure 6, the multiple input focusing channels 75 are spaced apart by a first separation distance D1 in a separation direction S parallel to the input focusing plane P1 and perpendicular to the acceptance direction A. The multiple output focusing channels 76 are spaced apart by a second separation distance D2 in the separation direction S, which is equal to or substantially equal to the first separation distance D1. In this example, the separation distances D1 and D2 for each pair of spaced-apart focusing channels 75 and 76 are equal. Therefore, the focusing channels 75 and 76 are evenly distributed on their respective code collectors 71 and 72 in the separation direction S.

[0074] In this particular example, the first focusing channel 75 of each of the multiple input focusing channels 75 is at the same height or level as the second focusing channel 76 of the multiple output focusing channels 76 in the separation direction S. As a result, the codes K can pass through the respective code collectors 71, 72 while remaining parallel to each other, i.e., without twisting, crossing, and / or entanglement.

[0075] As shown in Figure 7, the alternate input code collector 171 is provided with multiple input focusing channels 175 and / or multiple input guide positions 177, arranged in multiple rows and / or columns, forming an array, matrix, or grid of input focusing channels 175, thereby allowing more codes K of the first code group G1 to pass through the alternate input code collector 171. Note that only the first row or first column of the input focusing channels 175 extends to the input focusing surface P1. Other input focusing channels 175 may extend parallel to the input focusing channels 175 on the input focusing surface P1, or they may be slightly inclined with respect to the input focusing surface P1. The input focusing channels 175 are distributed across the alternate input code collectors 171, in which case all input focusing channels 175 and / or all input induction positions 177 are separated from each other in the separation direction S and / or spaced apart and / or each first focusing channel 175 and / or each input induction position 177 extends to its own level along the separation direction S.

[0076] It is clear that the first alternative code collector 171 shown in Figure 7 can also be used in place of the output code collector 72 in Figure 6.

[0077] As further shown in Figure 6, the first code alignment device 51 receives codes K from the first creel 21 in Figure 2, in multiple creel output directions Y that converge toward the first deflection device 51. Using the input code collector 71, the codes K can be neatly aligned toward the input focusing plane P1 regardless of the multiple creel output directions Y.

[0078] Furthermore, because of the input code collector 71, the first deflection device 51 can be positioned relatively close to each creel 21, even if, as a result, a relatively wide range of creel output directions Y converge toward the first deflection device 51. The distance between the first deflection device 51 and the first creel 21 is shown in Figure 2 as the creel output distance V between the front end of the first creel 21 and the input code collector of the first deflection device 51. Preferably, the creel output distance V is less than 150 centimeters, and more preferably less than 100 centimeters.

[0079] Similarly, after the code K exits the first deflection device 51 at the output code collector 72, it transitions from the output focusing surface P2 to the alignment surface P3, or to the alignment surface P3. In this example, the alignment surface P3 extends perpendicular to the output focusing surface P2. Note that the twisting of the first code group G1 in the region between the output code collector 72 and the code alignment device 41 does not affect the alignment surface and / or orientation of the same code K in the first deflection device 51 between the input code collector 71 and the output code collector 72.

[0080] Figure 8B shows how the codes K constituting the first code group G1 are input to and output to the first deflection device 51 at oblique angles with respect to the input focusing surface P1 and the output focusing surface P2, respectively. This oblique angle is exaggerated in the drawing for clarity. However, it should be understood that this oblique angle is relatively small, for example, only a few degrees, or may not exist at all.

[0081] Since the cords K are guided around the deflection member 51 in directions parallel to each other, the first group G1 of cords K can theoretically be deflected at any deflection angle H1 up to 360 degrees without the risk of the cords K twisting, crossing, or becoming entangled. Thus, the first deflection unit 51 and the other deflection devices 52-55 enable an entirely new range of layouts for the tire manufacturing plant 1 according to the present invention, including, but not limited to, the layouts shown in Figures 2-5.

[0082] In Figure 2, the multiple creels 21-25 are divided into a first group N1 of creels 21-23 and a second group of creels 23, 24 which can be connected alternately or alternately to the tire manufacturing apparatus 4. Groups N1 and N2 of creels 21-25 are located, positioned, and / or arranged on the opposite side of the central plane M. The central plane M is in a straight line and / or parallel to the cord supply direction F of the tire manufacturing apparatus 4.

[0083] The creel planes C1 to C5 of creels 21 to 55 extend at a creel offset angle H2 oblique to the cord supply direction F and / or the center plane M.

[0084] The creel surfaces C1, C2, and C3 of creels 21-23 belonging to the first creel group N1 are parallel to each other. Similarly, the creel surfaces C4 and C5 of creels 24 and 25 belonging to the second creel group N2 are also parallel to each other. However, the creel surfaces C1, C2, and C3 of creels 21-23 belonging to the first creel group N1 extend perpendicularly or perpendicularly to the creel surfaces C4 and C5 of creels 24 and 25 belonging to the second creel group N2.

[0085] Figure 3 shows an alternative tire manufacturing plant 101 according to a second exemplary embodiment of the present invention, which differs from the aforementioned tire manufacturing plant 1 in that the creels 21-25 extend at a creel offset angle H2 of 90 degrees with respect to the creel supply direction F and / or center plane M.

[0086] Figure 4 shows yet another alternative tire manufacturing plant 201 according to a third exemplary embodiment of the present invention. This plant differs from the alternative tire manufacturing plant 101 of Figure 3 in that the creels 221-225 are arranged in closer proximity. In particular, the first creel surface C1 and the second creel surface C2 are spaced apart by a distance W of less than 100 centimeters, preferably less than 80 centimeters, and most preferably less than 60 centimeters, in the lateral direction L perpendicular to the first creel surface C1. A similar distance W can be applied to other pairs of adjacent creels 221-225.

[0087] Each creel 221-225 is movable relative to adjacent creels 221-225 in a replacement direction E parallel to the creel surfaces C1-C5. For example, a second creel 222 is movable relative to the first creel 221 and the third creel 223 in the replacement direction E. The second creel 222 is movable between a supply position flush with the first creel 221 and the third creel 223 in the replacement direction E, and a replacement position, as shown in Figure 4, where the second creel 222 is at least partially retracted relative to the first creel 221 and the third creel 223 in the replacement direction E. In this way, at least a portion of the second creel 222 is accessible for maintenance and / or replenishment. Alternatively, the second creel 222 can be replaced and / or swapped entirely with a replacement creel (not shown).

[0088] It should be noted that the creels 221-225 in Figure 4 have considerably shorter lengths in the direction parallel to their respective creel surfaces C1-C5 compared to the creels 21-25 of the previously described embodiment. In particular, creels 221-225 can only accommodate 30 or fewer creel bobbins. Preferably, they can accommodate 20 or fewer creel bobbins. Alternatively, the creels 221-225 may have lengths of less than 4 meters, preferably less than 3 meters, in the direction parallel to their respective creel surfaces C1-C5. Therefore, the capacity of creels 221-225 will be smaller. However, this can be compensated for by providing, for example, at least 3, at least 5, or at least 8 creels in each group N1, N2. Each creel 221-225 can be retracted in the manner described above, and each creel 221-225 can be replaced, maintained, and / or replenished.

[0089] In particular, the layout in Figure 4 allows for the automatic removal and replacement of one or more creels 221-225 using automated replacement tools 208, such as robots and automated vehicles, especially automated guided vehicles (AGVs) and autonomous mobile robots (AMRs). This allows creels 221-225 to be removed from their respective groups N1, N2 for service, replenishment, and / or preparation at a location away from the operational creels 221-225.

[0090] Figure 4 shows only one automatic exchange tool 208 as an example. However, it goes without saying that each creel 221-225 may have its own dedicated automatic exchange tool 208. Alternatively, one or more automatic exchange tools 208 can be docked to each creel 221-225, or detached from each creel 221-225 to pick up other creels 221-225.

[0091] Preferably, the creels 221-225 are replaced together with their respective deflection devices 51-55. This ensures that when each creel 221-225 is removed from its respective group N1, N2, the code K is threaded through the code collectors 71, 72 of the respective deflection devices 51-55. This completes the preparation of the creels 221-225 for connection to the tire manufacturing apparatus 4.

[0092] Figure 5 shows yet another alternative tire manufacturing plant 3301 according to a third exemplary embodiment of the present invention. Unlike yet another alternative tire manufacturing plant 201 in Figure 4, this facility has creels 321-325 that are movable in an alternative replacement direction E' parallel to the lateral direction L, and space is provided for accessing the individual creels 321-325. In Figure 5, all creels 323 to the right of the second creel 322 are moved away from the second creel 322 along the alternative replacement direction E', creating a passage to the second creel 322.

[0093] Figures 9 and 10 show yet another alternative tire manufacturing plant 401, which differs from the aforementioned tire manufacturing plants 1, 101, 201, and 301 in that the creels are replaced by stock reels 421, 422, and 423. Each stock reel 421, 422, and 423 holds a set of cords that are unwound from their respective stock reels 421, 422, and 423 toward their respective deflection devices 451, 452, and 453. The cord sets may be wound onto the stock reels 421, 422, and 423 independently and / or elsewhere during the creel preparation stage, long before it is necessary to embed the cord sets into the tire parts during extrusion molding. In particular, multiple stock reels may be stored, for example, in a warehouse until they are needed in the further alternative tire manufacturing plant 401.

[0094] Depending on the orientation of the stock reels 421, 422, and 423, the first code collector or input code collector may be unnecessary or optional. In particular, each stock reel 421, 422, and 423 has stock reel axes R1, R2, and R3. When each of the stock reel axes R1, R2, and R3 of the stock reels 421, 422, and 423 is oriented parallel or substantially parallel to the input focusing plane P1, and in this example perpendicular or substantially perpendicular, the code is supplied directly from each stock reel 421, 422, and 423 to the deflection member 61. When the stock reel axes R1, R2, and R3 are oriented orthogonal or perpendicular to the input focusing plane P1, or when the stock reel axes R1, R2, and R3 are oriented in the aforementioned directions, it will be understood that the first code collector or input code collector is still usable, thereby providing the same technical advantages described above in relation to the above embodiments.

[0095] Considering the above, both the aforementioned creels 21-25, 221-225, 321-325 and the stock reels 421, 422, 423 described hereby have the function of supplying groups G1-G3 of code K to their respective deflection devices 51-55, 451, 452, 453, and therefore can be referred to as “supply stations” throughout the entire application and claims.

[0096] A method for manufacturing cord-reinforced tire components using one of the aforementioned tire manufacturing plants 1, 101, 201, 301, and 401 will be briefly described with reference to Figures 8A, 8B, and 8C.

[0097] Figure 8A shows the deflection member 61 in the retracted position after moving in the tension direction T. As a result, the first cord group G1 is received from the first creel 21 into the first deflection device 51.

[0098] The kth group G1 of code K can be passed through the input code collector 71 located in the holder 63 of the first deflection device 51, or, if the input code collector 71 is removable from the holder 63, it can be passed through the input code collector 71 at a location away from the holder 63. Similarly, the first group G1 of code K can be passed through the output code collector 72 located in the holder 63 of the first deflection device 51, or, if the output code collector 72 is removable from the holder 63, it can be passed through the output code collector 72 at a location away from the holder 63. Code K may also be already located in the first code deflection device 51 or at a location away from it that is directed toward and / or through the code alignment device 41.

[0099] Once all the cords K are correctly positioned in the cord collectors 71, 72 and the cord alignment device 41, the cords K are loosely guided along the deflection member 61 of the first deflection device 51. Next, the deflection member 61 of the first deflection device 51 is returned in the tension direction T toward and / or to the operating position in Figure 8C and / or to contact the cords K. The cords K of the first cord group G1 are now deflected around the deflection member 61 of the first deflection device 51. The tension applied to the cords K by the deflection member 61 automatically untangles any tangled or crossed cords K. If necessary, and if the untangling is unsuccessful on the first attempt, the deflection member 61 can be repeatedly moved back and forth in the tension direction T.

[0100] The same process can be repeated in each of the additional deflection devices 52-55 among the multiple deflection devices 51-55 in each of the tire manufacturing plants 1, 101, and 201 shown in Figures 2-5.

[0101] The same process may be performed in a similar manner and repeated for each stock reel 421, 422, 423 and for each deflection device 451, 452, 453 of the further alternative tire manufacturing plant 401 in Figures 9 and 10, and optionally, if the input code collector is not included in the further alternative tire manufacturing plant 401, the step of passing code K through the input code collector may be skipped.

[0102] The extruder 42 of the tire manufacturing apparatus 4 in Figure 2 is then started and begins to embed the cord K into the extruded material, forming a cord-reinforced tire component.

[0103] As mentioned above, the creels 21-25 and 221-225 can be arranged in groups N1 and N2 of the creels 21-25 and 221-225. Similarly, the stock reels 421, 422, and 423 in Figures 9 and 10 can be arranged in the same manner as the creels 21-25 and 221-225. Next, code K is alternately connected to the tire manufacturing apparatus 4 from the first group N1 of the creels 21-23, 221-223 or stock reels 421-423, and from the second group N2 of the creels 24, 25, 224, 225 or stock reels 421-423. Meanwhile, the non-operating groups N1 and N2 of the creels 21-25, 221-225 or stock reels 421-423 can be serviced, maintained, replenished, or, in the case of the tire manufacturing plants 202 and 302 in Figure 4 or Figure 5, completely replaced.

[0104] It should be understood that the above description is intended to illustrate the operation of a preferred embodiment and does not limit the scope of the invention. From the above discussion, it will be apparent to those skilled in the art that many variations fall within the scope of the invention. [Explanation of Symbols]
