Description

[0001] This application is a divisional application of the utility model patent application with application number 202321177567.7, application date May 16, 2023, and utility model name "Guiding device and winding station for guiding lining relative to tire components". Technical Field

[0002] The utility model relates to a winding station for winding a tire component around a raw material reel. Background Art

[0003] The known winding station comprises a stock reel for winding the tire components and a liner reel for adding or attaching the liner to the tire components before winding the tire components onto the stock reel. The liner prevents the tire components from sticking to each other in subsequent turns around the stock reel. The liner is supplied from the liner reel to the stock reel along a liner path. The known winding station is usually provided with a set of fixed guide rollers for guiding the liner along the liner path. Utility Model Content

[0004] A disadvantage of the known winding stations is that the liner may not be perfectly centering relative to the tire component when it is attached to it. When the liner is applied in an off-center position, the liner may protrude beyond the longitudinal sides of the tire component more on one side than on the other. The liner may turn suddenly in the axial direction of the stock reel and may deform and / or accumulate against the side flanges of said stock reel, causing wrinkles or creases in the liner or even in the tire component.

[0005] The object of the utility model is to provide a winding station for winding a tire component around a stock reel, wherein the positioning of the liner relative to the tire component can be improved.

[0006] The utility model provides a winding station for winding a tire component around a stock reel, wherein the winding station comprises: a stock reel portion, the stock reel portion is used to receive the stock reel; a liner reel portion, the liner reel portion is used to receive the liner reel; and a group of connecting rollers, the group of connecting rollers defines a connecting position in a liner path between the liner reel portion and the stock reel portion, the liner is connected to the tire component at the connecting position, wherein the winding station also comprises an anti-wrinkle device, the anti-wrinkle device is located in a pressing position between the connecting position and the stock reel portion, and is used to press on the tire component, wherein the liner reel portion is located in the pressing position opposite to the anti-wrinkle device. When the tire component is wound onto the stock reel, the pressing can reduce, smooth, flatten or iron out wrinkles in the tire component. By providing a liner reel portion opposite the anti-wrinkle device in the pinching position, the tire component and / or the liner can be supported on the liner reel or on the windings of the liner on the liner reel relative to the anti-wrinkle device in the pinching position.

[0007] Preferably, the anti-wrinkling device comprises one or more anti-wrinkling rollers for pressing on the tire component. The one or more anti-wrinkling rollers can roll over the tire component while applying pressure to the tire component.

[0008] More preferably, the anti-wrinkle device further comprises a lever pivotable about a pivot axis, wherein the one or more anti-wrinkle rollers are supported by the lever at a first side of the pivot axis at the squeezing position spaced from the pivot axis. The spacing of the one or more anti-wrinkle rollers from the pivot axis may generate a moment allowing the one or more anti-wrinkle rollers to press onto the tire component by their own weight, mass or gravity.

[0009] Most preferably, the anti-wrinkle device further comprises a weight holder for adding one or more weights on the lever at the first side of the pivot axis. The one or more weights can increase the moment, thereby generating a higher pressure applied by the one or more anti-wrinkle rollers to the tire component than the pressure applied by the weight of the one or more anti-wrinkle rollers alone.

[0010] In another embodiment, the anti-wrinkle device further comprises a weight holder for adding one or more weights to the lever at a second side of the pivot axis opposite to the first side. The one or more weights can at least partially offset the weight of the one or more anti-wrinkle rollers and / or balance the lever.

[0011] In another embodiment, the anti-wrinkle roller is two anti-wrinkle rollers for pressing on the tire component. By providing two anti-wrinkle rollers, the tire component can be pressed twice, thereby further smoothing, flattening or ironing the wrinkles in the tire component.

[0012] In another embodiment, the anti-wrinkle device comprises a frame for holding two anti-wrinkle rollers in a pinching position relative to a lever, wherein the frame is rotatable relative to the lever about a rotation axis, wherein the two anti-wrinkle rollers are arranged in a mutually parallel orientation on opposite sides of the rotation axis. Thus, the orientation of the frame as a whole including the two anti-wrinkle rollers can be adjusted to (automatically) match the orientation of the tire component in the pinching position.

[0013] In another embodiment, the anti-wrinkle device is configured to press the one or more anti-wrinkle rollers against the tire component only under the influence of gravity. Therefore, no separate drive device or controller is required to compress the tire component.

[0014] Whenever possible, the various aspects and features described and shown in the specification can be applied separately. These separate aspects can be the subject of divisional utility model applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 3 Shows Figure 1 An isometric view of an anti-wrinkle device; and

[0019] Figure 4 A side view of an alternative winding station according to a second exemplary embodiment of the present invention is shown. DETAILED DESCRIPTION

[0020] Figure 1 A winding station 100 according to a first exemplary embodiment of the present invention is shown for winding a tire component T together with a liner L around a stock reel 101. The same winding station 100 can alternatively be used to unwind a tire component T from a stock reel 101. The tire component T, in particular the breaker layer, is manufactured in a tire component production line (not shown) upstream of the winding station. The tire component T is stored in the form of several coils on the stock reel 101 so as to be used later as raw material in a tire building process.

[0021] The winding station 100 includes a stock reel portion 110 for receiving a stock reel 101 and a liner reel portion 120 for receiving a liner reel 102. The stock reel 101 and the liner reel 102 can be inserted into the winding station 100 together as part of a cassette. The liner L is supplied from the liner reel 102 to or toward the stock reel 101 along a liner path P. The winding station 100 includes a set of connecting rollers 131-133 that define a connecting position J of the liner L to the tire component T in the liner path P between the liner reel portion 120 and the stock reel portion 110. In this example, the set of connecting rollers 131-133 are arranged in a so-called "peeling" configuration to form an "Ω"-shaped ring in the liner L. This configuration is used when the winding station 100 or the cassette is operated in an unwinding mode to separate the liner L from the tire component T.

[0022] like Figure 1 As further seen in FIG. 1 , the winding station 100 comprises a guide device 1 for guiding the liner L relative to the tire component T before winding it on the stock reel 101. In this example, the guide device 1 is located between the liner reel portion 120 and the joining location J.

[0023] like Figure 2A , Figure 2B and Figure 2C In more detail, the guide device 1 comprises a centering roller, alignment roller or steering roller 2 for centering, aligning or guiding the liner L along the liner path P. The guide device 1 also comprises a holder 3 for holding the steering roller 2 and a base 4 for supporting the holder 3 relative to the liner path P. The steering roller 2 is rotatable about a roller axis A1. Figure 2A The neutrally oriented roller axis A1 is shown extending perpendicular to the lining path P.

[0024] When compared Figure 2A , Figure 2B and Figure 2C , it is clear that the steering roller 2 can also be rotated, pivoted, turned or tilted about a steering axis A2 which is transverse or perpendicular to the roller axis A1. In particular, the holder 3 and the steering roller 2 can be tilted together about the steering axis A2 relative to the base 4. In addition, in this example, the steering axis A2 is also transverse or perpendicular to the lining path P. Moreover, in this example, the steering axis A2 is spaced apart from the roller axis A1, in particular in a direction parallel to the lining path P. Preferably, the steering axis A2 is located downstream of the roller axis A1 in the supply direction of the liner L from the liner reel portion 120 towards the coupling position J.

[0025] In this exemplary embodiment, the steering axis A2 is located outside the steering roller 2. In addition, the steering axis A2 is located outside the retainer 3 and / or the base 4. In fact, the steering axis A2 is located outside the physical boundaries of the guide device 1 as a whole. The steering axis A2 can therefore be considered as a "virtual" axis. In particular, the inclination around the "virtual" steering axis A2 is obtained by providing one of the base 4 and the retainer 3 (in this example, the retainer 3) with an arc-shaped tilting element 31, 32, in particular a slot, which extends to the steering axis A2 along an arc C concentric with the steering axis A2 with a radius R. The other of the base 4 and the retainer 3 (in this example, the base 4) includes a coupling element 41, 42, in particular a pin, which can be moved along the arc-shaped tilting elements 31, 32. In particular, each pin engages with a corresponding one of the slots and / or protrudes through a corresponding one of the slots.

[0026] Alternatively, the holder 3 and the base 4 may physically extend up to the turning axis A2 to be coupled to each other at said turning axis A2, for example via a hinge or a bearing.

[0027] By tilting the steering roller 2 about the steering axis A2, any misalignment or deviation of the liner L in a lateral direction Y transverse or perpendicular to the liner path P can be corrected, offset or reversed.

[0028] like Figure 2A , Figure 2B and Figure 2C As shown, the guide device 1 further comprises a tilt actuator or tilt drive 5 which is coupled, connected or connectable to the holder 3 for rotating said holder 3 about the steering axis A2.

[0029] In this example, the tilt drive 5 is configured for pushing or pulling the holder 3 in the push / pull direction D at least with a vector component V tangential to the arc C. In particular, the tilt drive 5 is a linear drive, for example a cylinder 51 , which can be extended linearly in the push / pull direction D. The distal end of the tilt drive 5 is coupled to the holder 3 via an articulated connection or hinge 52.

[0030] Alternatively, the tilting drive 5 can be a rotary drive, for example a servomotor, which is directly engaged to the holder 3 at the steering axis A2 .

[0031] like Figure 2A , Figure 2B and Figure 2CAs further shown, the guide device 1 comprises side edge sensors 61, 62 for detecting side edges E1, E2 of the liner L in the lateral direction Y. The guide device 1 further comprises a control unit 7, which is operatively, electronically and / or functionally connected to the tilt drive 5 and the side edge sensors 61, 62. The control unit 7 is arranged, adjusted, programmed and / or configured to control the tilt drive 5 in response to signals received from the side edge sensors 61, 62 so as to rotate the steering roller 2 around the steering axis A2. For example, when the first side edge sensor 61 sends a signal indicating that the first side edge E1 of the liner L has been detected, the control unit 7 controls the tilt drive 5 to rotate the retainer 3 to the position as shown in FIG. Figure 2B Similarly, when the second side edge sensor 62 sends a signal indicating that the second side edge E2 of the liner L has been detected, the control unit 7 controls the tilt drive 5 to rotate the retainer 3 to the orientation shown. Figure 2C Orientation shown.

[0032] Alternatively, the side edge sensors 61 , 62 may be disposed at or near the tire component T for detecting the side edge of the tire component T in the lateral direction Y and correcting, aligning and / or steering the liner L in response to the detected side edge of the tire component T.

[0033] like Figure 1 As shown, the winding station 100 further includes a positioning drive 104 for moving the steering roller 2 from an inoperative position X1 shown in dashed lines, separated from the liner path P, to a steering position X2 shown in solid lines, located at or intersecting the liner path P. The steering roller 2 can, for example, be moved away from the liner path P so that it does not interfere with the initial (manual) feeding of the liner L along the liner path P. Moreover, the position of the steering roller 2 relative to the liner path P can be actively controlled to control the amount of pressure applied by the steering roller 2 to the liner L.

[0034] exist Figure 1 in Figure 1 Considered in the drawing plane of FIG. , the turning roller 2 is shown in a position approaching the liner L from the right-hand side of the liner path P. However, it should be understood that this situation can be very well reversed or mirrored with respect to the liner path P, i.e. Figure 1 Considered in the drawing plane of , the deflection roller 2 approaches the lining L from the left-hand side of the lining path P.

[0035] The winding station 100 may also include one or more guide rollers 151, 152 for guiding the liner L along the liner path P. Preferably, the one or more guide rollers 151, 152 are positioned so that the liner L extends along a considerable circumferential length of the turning roller 2, thereby providing sufficient friction between the turning roller 2 and the liner L to obtain the aforementioned turning, alignment or centering effect.

[0036] like Figure 1 As further shown, the winding station 100 comprises an anti-wrinkle device 201, which is located or positioned between the connection position J and the stock reel portion 110, for pressing on the tire component T at the pressing position W. The anti-wrinkle device 201 comprises a set or a pair of anti-wrinkle rollers 211, 212 for pressing on the tire component T. The anti-wrinkle rollers 211, 212 extend parallel to each other and / or can rotate around mutually parallel rotation axes. Alternatively, only a single anti-wrinkle roller 211 can be provided.

[0037] This pressing may reduce, smooth, flatten or iron out wrinkles in the tire component T as it is wound onto the stock reel 101 .

[0038] like Figure 3 As best seen in FIG. 1 , the anti-wrinkle device 201 comprises an arm or lever 202 that can rotate, turn or pivot about a pivot axis A3. In this example, the lever 202 comprises a first lever portion 221 and a second lever portion 222 that extend parallel to each other. The anti-wrinkle rollers 211, 212 are supported by the lever 202 at a position spaced from the pivot axis A3 in a pressing position W. In particular, the pressing position W is located at a first side S1 of the pivot axis A3.

[0039] The anti-wrinkle rollers 211, 212 press on the tire component T only under the influence of gravity G. The anti-wrinkle device 201 also includes a weight holder 203 for adding one or more weights 230 on the lever 202 at the first side S1 of the pivot axis A3. Therefore, the amount of pressure applied by the anti-wrinkle rollers 211, 212 on the tire component T can be changed or adjusted.

[0040] In this example, the anti-wrinkle driver 201 is additionally provided with a weight holder 204 for adding one or more weights 240 to the lever 202 at a second side S2 of the pivot axis A3 opposite to the first side S1. Thus, the lever 202 can be balanced and / or at least a portion of the weight of the lever 202, the anti-wrinkle rollers 211, 212 and / or the counterweight 230 can be offset.

[0041] In this exemplary embodiment, the balancing mass 230 and the counterweight 240 are shaped as annular bodies, which can be concentrically mounted on the balancing mass holder 203 and the counterweight holder 204, respectively.

[0042] The anti-wrinkle device 201 includes a frame 205 for holding two anti-wrinkle rollers 211, 212 in a compression position W relative to the lever 202. The frame 205 can rotate, pivot or turn relative to the lever 202 about a rotation axis A4. The rotation axis A4 is parallel or substantially parallel to the pivot axis A3. The two anti-wrinkle rollers 211, 212 are arranged on opposite sides of the rotation axis A4 in a mutually parallel orientation. Therefore, the orientation of the frame 205 as a whole including the two anti-wrinkle rollers 211, 212 can be adjusted to match the orientation of the tire component T at the compression position W.

[0043] Figure 4 An alternative winding station 300 according to a second exemplary embodiment of the present invention is shown, which is different from the aforementioned winding station 300 only in that it has a liner reel portion 320 in an alternative position, which is close to or near the anti-wrinkle device 201 in the squeezing position W, is at the anti-wrinkle device or is directly opposite to it, so that the tire component T and / or the liner L can be supported on the liner reel 102 relative to the anti-wrinkle device 201 in the squeezing position W or on the winding of the liner 102 on the liner reel 102.

[0044] Alternatively, a support roller, a support conveyor, or another suitable support element may be provided at the pressing position W to support the tire component T and / or the liner L relative to the anti-wrinkle device 201 .

[0045] Now refer to Figures 1 to 3 A method for guiding the liner L relative to the tire component T before winding the tire component T on the stock reel 101 using the above-described winding station 100, 300 is briefly described.

[0046] like Figure 1 As shown, the liner L is guided along the liner path P using the steering roller 2. The steering roller 2 is moved to the working position X2 to press against the liner L. Initially, the orientation of the steering roller 2 will be neutral, as shown in FIG. Figure 2A The steering roller 2 can then be tilted around the steering axis A2, as shown. Figure 2B and Figure 2C As shown, the liner L is corrected for any misalignment relative to the tire component T. In particular, the purpose of the correction is to align or center the liner L relative to the tire component T.

[0047] As previously mentioned, the tilting of the steering roller 2 about the steering axis A2 may be responsive to the detection of one or both lateral edges E1 , E2 of the liner L (or tire component T) in the lateral direction Y perpendicular to the path P of the liner.

[0048] like Figure 1As shown, the method may further include the step of using the above-mentioned anti-wrinkle device 201 to press on the tire component T at the pressing position W between the connecting position J and the stock reel 101. In this example, the anti-wrinkle rollers 211, 212 press on the tire component T only under the influence of gravity G.

[0049] Optionally, a balancing mass 230 and / or a counterweight 240 may be added to balance or adjust the pressure applied to the tire component T by the anti-wrinkling rollers 211 , 212 .

[0050] It should be understood that the above description is included to illustrate the operation of the preferred embodiment and is not intended to limit the scope of the utility model. From the above discussion, many variations still included in the scope of the utility model will be apparent to those skilled in the art.
