Description

Technical Field

[0001] The utility model relates to a stripper for stripping a liner from a raw material before the raw material is supplied to a tire building machine, and also relates to a stripping station for stripping the liner from the raw material and preventing the raw material from being on tire components. Background Art

[0002] The stripping station is used to supply raw material to the tire building machine. Known stripping stations are configured to receive a replaceable cassette containing a storage reel, a liner reel, and a stripper. The raw material is stored in several coils on the storage reel, ready to be unwound by the stripping station and supplied to the tire building machine. The coils are separated by one or more layers of liner to prevent subsequent coils from adhering to or sticking to one another. The liner reel is used to collect the liner as the raw material is unwound. The stripper includes multiple guide members that define a liner path through the stripper to the stripping edge, along which the liner is finally separated from the raw material. The raw material is then supplied to the tire building machine. The guide members are supported from only one side, allowing an operator to manually guide a new length of liner through the liner path from the opposite side.

[0003] A known raw material supplied in this manner is a set of radio frequency identification (RFID) tags supported at spaced locations along the liner. Each RFID tag is intended to be embedded in a raw or uncured tire for identification purposes.

[0004] WO 2022 / 90889A1 discloses a method for applying a rubberized electronic tag to a tire, in which the tag is gradually peeled off from a continuous belt, which continues along a loop section without the tag, is then reattached with reduced adhesion, and is finally separated from the continuous belt at the peeling edge.

[0005] JP 2009-107668 A and JPS 61127429 A disclose similar devices for gradually peeling a label from a liner in two steps. EP 3 383 155 A1 also discloses a feeder for feeding out a storage strip carrying electronic components, having a strip bending device for similarly reducing adhesion of the components to the upper strip, and having a cover that can be opened to expose the side surface of the roller so that the storage strip can be easily placed on the roller from the exposed side. Utility Model Content

[0006] A disadvantage of the known strippers is that the raw material is pulled along with the liner downstream of the stripping edge and / or the raw material cannot be reliably separated from the liner.

[0007] The object of the present invention is to provide a stripper, a stripping station and a method for stripping a liner and a raw material from each other, wherein the raw material can be separated from the liner more reliably.

[0008] According to a first aspect, the present invention provides a stripper for stripping a liner from a raw material, wherein the raw material includes portions supplied at spaced-apart locations on the liner, wherein the stripper includes a stripper plate and a plurality of guide rollers defining a liner path for feeding the liner on the stripper plate along a stripping edge of the stripper plate to strip and permanently separate the liner from the raw material, wherein the liner path extends in a guide plane, wherein the stripper includes a pre-stripper plate and a stripper slot extending perpendicular to the guide plane between the pre-stripper plate and the stripper plate, the stripper slot being configured to temporarily strip the liner from the raw material before permanently separating the liner from the raw material at the stripping edge, wherein the stripper further includes a width adjustment member positionable in the stripper slot for adjusting the width of the stripper slot, thereby enabling adjustment of the width when using thicker or thinner liners.

[0009] In one embodiment, the width adjustment member has an adjustment body defining a pre-stripping edge at a side of the stripper slot facing the pre-stripper plate.

[0010] Preferably, the adjustment body is adjustably fastened to said pre-stripper plate.

[0011] More preferably, the adjustment body is adjustably fastened to the pre-stripper plate by using an elongated adjustment slot.

[0012] In particular, the width is chosen to be at least 1.5 times the thickness of the pad, and preferably at least 2 times said thickness.

[0013] According to a second aspect, the present invention provides a stripping station comprising a stripper according to any embodiment of the first aspect of the present invention.

[0014] The various aspects and features described and illustrated in this specification may be applied independently wherever possible. These independent aspects may become the subject of divisional patent applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 and 2 Shown is a stripping station 100 for applying raw material 90 to a tire building machine (not shown) such as a tire building drum. The stripping station 100 is configured to receive a replaceable cartridge or cassette 1 having a stock reel holder 11 for holding a stock reel 81 and a liner reel holder 12 for holding a liner reel 82. The stripping station 100 and / or cassette 1 include a stripper 2 that is arranged to be positioned between the stock reel 81 and the liner reel 82 when the cassette 1 is received in the stripping station 100.

[0024] In this exemplary embodiment, raw material 90 is formed from various components, specifically RFID tags 91, which are stored in a plurality of coils on a storage reel 81, ready to be unwound and supplied to the tire building machine via a stripping station 100. The RFID tags 91 may be embedded in a viscous elastomeric material, preferably rubber, to facilitate attachment of the RFID tags to tire components. The coils are separated by one or more layers of liner 92 to prevent subsequent coils of raw material 90 from adhering or sticking to one another. The liner reel 82 is used to collect the liner 92 as the raw material 90 is unwound. The liner 92 is guided along a liner path L from the storage reel 81 to the liner reel 82.

[0025] The stripping station 100 and / or the cassette 1 may optionally be provided with a scraper 115 along the liner path L between the storage reel 81 and the stripper 2 in a scraping position C to scrape off any raw material 90 that is accidentally adhered to the underside of the liner 92. It should be noted that the scraping position C is positioned away from any other guide means of the stripping station 100 and / or the cassette 1. In particular, at the scraping position C, there is no guide means forming an opposing surface directly opposite the scraper 115. Therefore, raw material 90 that is adhered to the upper side of the liner 92 can pass through the scraping position C unhindered.

[0026] like Figure 5A and 5B Shown in more detail, the scraper 115 has a resiliently flexible scraper body 116 that is mounted to the stripping station 100 or cassette 1 in a position where it intersects the liner path L without the liner 92, as shown in dashed lines, and when the liner 92 is present at the liner path L, the resiliently flexible scraper body 116 is pressed against the liner 92 and / or deflected by the liner 92, as shown in solid lines. The scraper body 116 also has an acutely angled or pointed tip portion 117, i.e., a tip portion 117 having an acute angle or V-shaped profile, for effectively separating any raw material 90 that is accidentally adhered to the underside of the liner 92. The bending stress in the scraper body 116 ensures that the scraper 115 remains tightly pressed against the liner 92. In particular, the scraper body 116 is selected to have sufficient flexibility so that the tip portion 117 becomes aligned or fully aligned with the direction of the pad 92 at the pad path L. One or more cutouts 118, 119 can be provided to subtly weaken the scraper body 116 or to facilitate bending of the scraper body 116 where it is intended to bend.

[0027] like Figure 3 and 4 As best shown in FIG, the stripper 2 includes a pre-stripper plate 31, a stripper plate 32, and a plurality of guide rollers 41, 42, 43 defining a liner path L extending through the stripper 2 in a guide plane P. The stripper 2 also includes an output roller 44 for outputting the raw material 90 after it has been separated from the liner 92. The guide rollers 41, 42, 43 and the output roller 44 are rotatable about respective mutually parallel rotation axes R1, R2, R3, R4 extending in an axial direction X perpendicular or substantially perpendicular to the guide plane P.

[0028] The stripper 2 is provided with a frame or base member 20 for supporting, from a first side A of said guide plane P, a pre-stripper plate 31 , a stripper plate 32 and a plurality of guide rollers 41 , 42 , 43 .

[0029] The pre-stripper plate 31 and the stripper plate 32 extend on opposite sides of a stripper slot S, which extends perpendicular to the guide plane P, and are used to initially strip the liner 92 and the stock material 90 from each other as the stock material 90 traverses the stripper slot S. In other words, the liner 92 is stripped from the stock material 90, or the stock material 90 is stripped from the liner 92. The pre-stripper plate 31 defines a pre-stripping position, in which the liner 92 is temporarily stripped from the stock materials 90, 91, or vice versa. The stripper plate 32 defines a re-engaging position, in which the liner 92 is re-engaged with the stock material 90. The pre-stripping and re-engaging positions are located very close together, so that the stock material 90 loses support only for a very brief period of time as it traverses the stripper slot S.

[0030] The guide rollers 41, 42, 43 include a return roller 41 positioned along the liner path L below the stripper slot S for receiving the liner 92 from the pre-stripping position and for returning the liner 92 to the re-engagement position. The return roller 41, the pre-stripper plate 31, and the stripper plate 32 together define a so-called "omega (Ω)"-shaped portion of the liner path L.

[0031] The stripper slot 2 is often located at a second side B of the guide plane P, opposite the first side A, for manual insertion or placement of the liner L between stripping operations.

[0032] like Figure 3 As best shown, the stripper 2 further includes a width adjustment member 7 positionable in the stripper slot S for adjusting the width of the stripper slot S. Specifically, the width adjustment member 7 has an adjustment body 70 that defines a pre-stripping edge V1 at the side of the stripper slot facing the pre-stripper plate 31. The adjustment body 70 is adjustably secured to the pre-stripper plate 31, for example, by using elongated adjustment slots 71, 72. The width of the stripper slot S is preferably adjusted to at least 1.5 times or at least 2 times the thickness of the liner P2.

[0033] The stripper plate 32 has a wedge-shaped body that defines a stripping edge V2. The stripping edge V2 is relatively sharp, or at an acute angle, to effectively strip the liner 92 from the stock material 90.

[0034] The guide rollers 41, 42, 43 also include one or more rear separator rollers 42, 43 positioned downstream of a final peeling location along the liner path L where the liner 92 is permanently separated from the stock material 90, 91. The one or more rear separator rollers 42, 43 guide the liner 92 toward the liner reel 82.

[0035] The output roller 44 is driven, actively driven, actively rotated, and / or driven to rotate about its rotation axis R4 to ensure that the raw material 90 is pulled onto the output roller 44 and does not follow the liner 92 along the liner path L downstream of the final stripping position. In this example, the stripper 2 includes a transmission 21 between the output roller 44 and one of the guide rollers 42 among the plurality of guide rollers 41-43. The transmission 21 is configured to drive the rotation of the output roller 44 by the rotation of the guide roller 42. In this case, the transmission 21 includes two meshing gears. Thus, the output roller 44 is driven in a rotational direction opposite to the guide roller 42 to which it is coupled. Various types of mechanical transmissions, such as chains, belts, or the like, can be used, provided that the correct rotational direction of the output roller 44 is ensured by coupling the output roller 44 to one of the guide rollers 41, 42, 43. For example, a belt driving both rollers 43, 44 in the same rotational direction can be used to couple the output roller 44 to the final guide roller 43 along the liner path L.

[0036] In another alternative embodiment, the output tube 44 may be driven directly, for example, by a servo drive (not shown).

[0037] The transmission 21 is configured to drive the output roller 44 to rotate in a certain transmission ratio with respect to the rotation of the one guide roller 42 , resulting in the output roller 44 and the one guide roller 42 having the same or substantially the same circumferential speed on their circumferential surfaces.

[0038] In this example, if Figure 1 As shown, the output rollers 44 are configured to support the raw material 90 on a pick-up plane E1 that is parallel to, or substantially parallel to, the horizontal plane E2. More particularly, the pick-up plane E1 is collinear, coincident, and / or parallel to the plane defined by the stripper plate 32. Alternatively, as Figure 7 As shown, the output roller 44 can be slightly higher (as shown) or slightly lower (not shown) than the stripper plate 32 so that the pick-up plane E1 can be arranged at a pull angle of less than 45 degrees, preferably less than 30 degrees, and most preferably less than 15 degrees relative to the horizontal plane E2. At such a pull angle E3, the output roller 44 pulls the raw material 90 onto the output roller 44 at the pull angle E3. The output roller 44 can stop when the raw material 90 is completely separated from the liner 92, thereby leaving the raw material 90 in the angled pick-up plane E1, or can be further rotated until the raw material 90 is again positioned in or parallel to the horizontal plane E2.

[0039] It should be noted that there is a height difference H4 between the highest point of the output roller 44 and the upper surface defined by the stripper plate 32. The height difference H4 is preferably equal to or less than the radius of the output roller 44.

[0040] like Figure 3 and 4 As further shown, the output roller 44 includes a roller body 48. Figure 3 and 4 In the example shown, the roller body 48 is provided with a circumferential groove 45. The stripper 2 also includes an emitter 22, a reflector 23 and a receiver 24, which are positioned so that a light beam, in particular a laser beam, is emitted, reflected and received along a line of sight M passing through the circumferential groove 45. It should be noted that the reflector 23 can alternatively be positioned so as to reflect the light beam in another direction different from the direction in which it is received, in which case at least one of the incident beam or the outgoing beam extends along the aforementioned line of sight M. The emitter 22 and the receiver 24 can be integral as shown in the figure, or separate components. In another alternative embodiment, only an emitter such as a backlight and a receiver can be used on opposite sides of the output roller 44, or the reflector 23 can be replaced by a reflective portion of the raw material 90, which is provided with sufficient reflectivity.

[0041] Additionally or alternatively, the roller body 48 may be textured, contoured, or coated to prevent the raw material 90 from adhering to the surface. In particular, the roller body 48 may be provided with a plurality of circumferentially extending ribs (not shown). When combined with the previously mentioned circumferential grooves 45, the height of the circumferentially extending ribs is significantly less than the depth of the circumferential grooves 45, i.e., less than 20% or less than 10% of the depth.

[0042] like Figure 1 and 2 As shown, the stripping station 100 also includes a pick-and-place fixture 200 for picking up the raw material 90 from the output roller 44 and for placing the raw material 90 on the tire component 109. The pick-and-place fixture 200 can be rotatable about a redirection axis K to change the orientation of the raw material 90 relative to the tire component 9 before placement. Alternatively, the output roller 44 can be rotatable about a vertical redirection axis K for the same purpose.

[0043] like Figure 1 As shown in FIG. 4 , the stripper 2 includes a fixing member 6, which can be Figure 1 and 3 The open state shown is the same as Figure 2 and 4The securing member 6 is movable between the illustrated secured positions. In the open position, the securing member 6 facilitates convenient, free, or unimpeded access to the liner path L and / or the insertion or placement of a length of liner 92 into the liner path L from the second side B. In the secured position, the securing member 6 is arranged, configured, or adapted to secure, fasten, couple, interconnect, and / or fix at least two of the plurality of guide rollers 41, 42, 43 relative to one another in one or more securing directions D parallel to the guide plane of the second side B. The securing direction D can be different for each pair of guide rollers 41, 42, 43. In particular, the securing direction D is parallel to a line connecting the paired secured guide rollers 41, 42, 43.

[0044] In this example, the fixing member 6 fixes the return roller 41 , one of the rear separation rollers 42 , and the output roller 44 .

[0045] The fixing member 6 comprises a fixing bracket, finger or wall 60, which is connected to the rollers 41, 42, 44. The fixing arm 60 can be connected to the rollers 41, 42, 44. Figure 1 and 3 The open state shown is the same as Figure 2 and 4 The stripper 2 is hinged about a hinge axis H perpendicular to the guide plane P between the fixed states shown. The hinge axis H is spaced apart from the rotation axes R1, R2, R3 of the plurality of guide rollers 41, 42, 43. The stripper 2 includes a shaft or hinge member 40 at the hinge axis H, which is spaced apart from and / or not one of the guide rollers 41, 42, 43 and the output roller 44. A fixed arm 60 is hingedly connected to the hinge member 40 and is rotatable about the hinge axis H for engaging at least two guide rollers 41, 42 in the fixed state. Alternatively, the fixed arm 60 can be connected to one of the guide rollers 41, 42, 43 and the output roller 44.

[0046] The stripper 2 further comprises an alignment member 46 supported by the base member 20 from a first side A of the guide plane P for positioning, centering, or aligning the fixing member 6 in or relative to the fixed state. The alignment member 46 protrudes from the base member 20 in the axial direction X further than the guide rollers 41, 42, 43 and the output roller 44. In particular, the alignment member 46 is provided with a conical portion 47 that protrudes toward or faces the fixing member 6 at the second side B. The fixing member 6 is configured to engage the alignment member 46 when moved into the fixed state.

[0047] Alternatively, the fixing member 6 may be movable in a linear manner, ie by sliding it into or out of the fixing state, or it may be detachably mounted in the fixing state and separate from the stripper 2 in the open state.

[0048] like Figure 3 and 4 As shown, the fixed arm 60 has an arm body provided with a plurality of grooves, apertures or positioning portions 61-64 for positioning and / or slotting over the guide rollers 41, 42, the output roller 44 and / or the alignment member 46 from the second side B of the stripper 2 in a locking direction F parallel to the hinge axis H. The positioning portions 61-64 can be at least partially slotted over the distal ends of the respective rollers 41, 42, 44 and / or the alignment member 46, more particularly slotted over the bearing portions provided at the respective distal ends or, in the case of the alignment member 46, slotted over the conical portion 47 thereof.

[0049] In order to achieve the slotting movement, the fixing arm 60 is given another degree of freedom of movement in addition to the rotation about the hinge axis H. In particular, the fixing arm 60 can be moved in the pulling direction G opposite to the locking direction F from the following directions: Figure 4 Move the lock position shown to Figure 3 In the unlocked position shown, it is spaced apart from at least two guide rollers 41 , 42 .

[0050] In this example, the fixing member 6 further comprises a biasing member 65 for biasing the fixing arm 60 toward the locked position. More particularly, the biasing member 65 is a spring arranged in or at the hinge member 40. Thus, the fixing arm 60 can be pulled and released in a manner similar to that described above. Figure 4 The locked position shown is the same as Figure 3 Manually move between the unlocked positions shown.

[0051] like Figure 1 and 6 As shown, the box 1 or the stripping station 100 is provided with a first reel sensor 301 and a second reel sensor 302 for detecting the state of the storage reel 81. In particular, the first reel sensor 301 is arranged to detect the empty state of the storage reel 81, while the second reel sensor 302 is arranged to detect whether the storage reel 81 is present in the box 1 or the stripping station 100. To this end, the first reel sensor 301 is configured to emit a beam, such as a laser beam, which closely follows the hub 80 of the storage reel 81 but does not intersect with it. The second reel sensor 302 is configured to emit a beam, such as a laser beam, which intersects the hub 80 of the storage reel 81. The box 1 or the stripping station 100 is also provided with a reflector 303 for returning the beam to the corresponding reel sensor 301, 302.

[0052] In particular, the first reel sensor 301 receives its beam returned from the reflector 303 only when the stock reel is empty or nearly empty. In other words, the raw material 90, 91 and the liner 92 no longer block the beam of the first reel sensor 301. Similarly, the second reel sensor 302 receives its beam returned from the reflector only when the stock reel 81 is removed from the box 1 or the stripping station 100. In other words, the hub 80 no longer blocks the beam of the second reel sensor 302.

[0053] In practice, the liner 92 may have irregularities that may at least partially scatter the beam back to the respective reel sensors 301, 302. Such irregularities may be formed by ridges, indentations, or variations in the circumference of the liner 92, primarily due to the intermittent presence of the raw material 90, 91 on the liner 92 at different locations along the circumference of the liner 92 and in different turns of the liner around the hub 80 of the stock reel 81. This scattering is unpredictable and may result in false positive detection signals at the respective reel sensors 301, 302, such as a false positive detection indicating that the stock reel 81 is empty when it is not, or a false positive detection when the stock reel 81 has been removed.

[0054] In order to prevent or reduce such false positive detection results as much as possible, it has been found to be advantageous to place the reel sensors 301, 302 at tilted beam angles T1, T2, T3 to the vertical planes W1, W2. In particular, the reel sensors 301, 302 may be positioned as shown in FIG. Figure 1 As shown, it is oriented at an oblique angle relative to a vertical plane W1 parallel to the axis N of the stock reel, or as shown Figure 6 As shown, the pad 92 is oriented at an oblique angle relative to a vertical plane W2 perpendicular to the stock reel axis N, or at an oblique angle relative to both the vertical plane W1 and the vertical plane W2. The oblique beam angles T1, T2, and T3 are preferably at least 3 degrees, more preferably at least 5 degrees, even more preferably at least 8 degrees, and most preferably at least 10 degrees. At such oblique angles, the pad 92 is less likely to return a false positive.

[0055] Now refer to Figure 1 -4 illustrates a method for separating the liner 92 from the raw material 90 , particularly the RFID tag 91 , using the aforementioned peeler 2 .

[0056] Figure 1 and 3 The fixing member 6 is shown after it has been removed from its Figure 2 and 4After the respective fixed state shown is moved into its respective open state. The liner path L is accessible from the second side B. In particular, the portion of the liner path L extending through the stripper 2 is freely accessible along the entire length, at least within the stripper 2. As a result, a new length of liner 92 can be manually inserted or placed in the liner path L and / or guided or passed through the liner path L, for example when preparing a new cassette 1 or when inserting a new cassette 1 into the stripping station 100 before a stripping operation.

[0057] Figure 2 and 4 It shows how the fixing member 6 has subsequently been removed from its Figure 1 and 3 The respective open state shown is moved back into its respective fixed state. The fixing member 6 rigidly connects the at least two guide rollers 41 , 42 to each other, thereby providing a more accurate guidance of the pad 92 despite the force exerted by said pad 92 on the respective part of the stripper 2 .

[0058] As previously mentioned, the output roller 44 is driven. Therefore, when the raw material 90, in particular the RFID tag 91, is separated from the liner 92 at the final peeling position, the output roller 44 can pull the raw material 90 completely onto the output roller 44. As a result, the raw material 90 is no longer supported by the liner 92 and / or is completely separated from the liner 92.

[0059] The stock material 90 remains stationary on the output rollers 44 for subsequent picking by the pick and place fixture 200 .

[0060] It is understood that the above description is included to illustrate the operation of the preferred embodiment and is not meant to limit the scope of the present invention. From the above discussion, many variations will be apparent to those skilled in the art, which variations are also included within the scope of the present invention.
