Description

Technical Field

[0001] This invention relates to a peeler for separating the liner from the raw material before it is supplied to a tire forming machine. This invention also relates to a peeling station for separating the liner from the raw material and preventing the raw material from being placed on tire components. Background Technology

[0002] A stripping station is used to supply raw material to a tire forming machine. Known stripping stations are configured to receive a replaceable cassette housing a storage reel, a liner reel, and a stripper. Raw material is stored in several loops on the storage reel, ready to be unwound and supplied to the tire forming machine via the stripping station. The loops are separated by one or more layers of liner to prevent subsequent loops from adhering or sticking to each other. 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 up to a stripping edge, along which the liner is finally separated from the raw material. The raw material is then supplied to the tire forming machine. The guide members are supported only from one side, allowing an operator to manually guide a new length of liner through the liner path from the opposite side.

[0003] The raw material known to be supplied in this manner is radio frequency identification (RFID) tags supported at spaced intervals along the liner. Each RFID tag is designed to be embedded in an unfinished or uncured tire for identification purposes.

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

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

[0006] The known drawback of 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 purpose of this invention is to provide a peeler and a peeling station for separating the liner from the raw material, wherein the raw material can be separated from the liner more reliably.

[0008] According to a first aspect, the present invention provides a peeler for separating a liner from a raw material, wherein the raw material comprises portions supplied at spaced-apart locations on the liner, wherein the peeler includes a peeler plate and a plurality of guide rollers defining a liner path for feeding the liner on the peeler plate along a peeling edge of the peeler plate to peel it apart and permanently separate the liner from the raw material, wherein the peeler further includes an output roller for receiving the raw material after it has been permanently separated from the liner, wherein the output roller is driven.

[0009] By driving the output roller, the raw material can be prevented from being pulled along with the pad downstream of the peeling edge. In particular, once the raw material is separated from the pad, the driven output roller can effectively pull the raw material away from the pad. Furthermore, by driving the output roller, the raw material can be completely separated from the pad before being picked up by the pick-and-place unit, especially when the raw material is formed of different parts, and more particularly when it is a RFID tag.

[0010] Preferably, the stripper further includes a drive mechanism between the output roller and one of the plurality of guide rollers, the drive mechanism being used to drive the rotation of the output roller by the rotation of said guide roller. By driving the output roller via the drive mechanism, no separate drive device is required to drive the output roller.

[0011] More preferably, the transmission is configured to drive the rotation of the output roller at a transmission ratio with that of the guide roller, resulting in the output roller and the guide roller having the same or substantially the same circumferential speed on their circumferential surfaces. Therefore, the raw material is pulled away from the liner at the same or substantially the same speed as the liner being pulled toward the liner reel.

[0012] In one embodiment, the actuator includes one or a combination of meshing gears, chains, or belts. These mechanical actuators can establish a directional transmission relationship between the guide roller and the output roller.

[0013] Alternatively, the stripper includes a servo drive for directly driving the output rollers. This servo drive can be indirectly controlled, for example, based on sensor input regarding the liner speed.

[0014] In another embodiment, which can be used either in combination with or independently of the driven output roller, the output roller is provided with circumferential grooves. The circumferential grooves can be used for inspection or testing purposes, as will be explained in more detail later.

[0015] Specifically, the stripper also includes emitters, reflectors, and / or receivers, positioned such that a light beam, particularly a laser beam, is emitted, reflected, and / or received along a line of sight passing through the circumferential groove. Due to its characteristics, raw materials may be difficult to visually inspect. The interruption of the line of sight allows for accurate and reliable determination of whether the raw material has reached the output roller. If it is determined that the raw material has indeed reached the output roller, the driven rotation of the output roller can be stopped, holding the raw material in place on the output roller for subsequent pickup by a pick-up and placement fixture.

[0016] In another embodiment, which can also be used independently of the driven output roller, the padding path extends in the guide plane, wherein the peeler includes a base member for supporting a plurality of guide rollers from a first side of the guide plane, wherein the peeler also includes a fixing member at a second side of the guide plane opposite to the first side, the fixing member being movable between a fixed state and an open state, the fixed state being for fixing at least two of the plurality of guide rollers relative to each other at the second side in one or more fixed directions parallel to the guide plane, the open state being for spacing the at least two guide rollers apart so that the padding path is accessible from the second side.

[0017] Many of the guide rollers in the guide rollers define sharp turns in the liner path, which can cause the liner to exert excessive force on the guide rollers. In the closed state, the fixing member can form a rigid interconnection between at least two guide rollers on the second side, thereby reducing the tendency of the at least two guide rollers to move relative to each other when subjected to excessive force in the liner. At the same time, since the fixing member can move from the fixed state to the open state, it allows for convenient manual insertion or placement of new lengths of liner in the liner path from the second side, for example, when feeding new liner from the storage reel into the stripper. Therefore, when in the open state, the presence of the fixing member in the stripper does not interfere with the initial placement of the liner before the stripping operation.

[0018] Preferably, in the fixed state, the fixing member secures the output roller relative to at least two guide rollers in one or more fixed directions on the second side. This also allows for more precise positioning of the output roller relative to other guide rollers and / or the peeler plate.

[0019] In another embodiment, the stripper includes a pre-stripper plate and a stripper groove extending perpendicular to the guide plane between the pre-stripper plate and the stripper plate. The stripper groove is used to temporarily separate the pad and the raw material from each other before permanently separating them at the stripping edge. At least two guide rollers include return rollers positioned below the stripper groove for receiving the pad from the stripper groove and for returning the pad to the stripper groove. The pad can thus follow a so-called "omega (Ω)" shaped pad path, temporarily separated from the raw material at the pre-stripping position, looping around the return roller, and returning to the pad at a re-engagement position near the initial stripping position, where the raw material has initially separated from the pad. This initial stripping of the pad from the raw material reduces the adhesion or bond between the raw material and the pad, making it easier to permanently separate the pad from the raw material at the final stripper guide. The fixing member can fix the position of the return roller not only relative to the other guide rollers among at least two guide rollers, but also relative to the pre-stripper guide, the stripper guide, and / or the stripper groove. In other words, the so-called "omega" portion of the liner path is defined by the portion of the stripper at the second side that can be rigidly positioned relative to each other.

[0020] Preferably, the fixing member includes a fixing arm that, in the fixed state, connects at least two guide rollers to each other. The fixing arm can effectively reach from one guide roller to another within the guide roller group.

[0021] More preferably, the retaining arm can be hinged between a fixed state and an open state about a hinge axis perpendicular to the guide plane. Therefore, the retaining arm can be rotated into the fixed state or out of the rotating state, thereby allowing the insertion of a new length of pad from the second side.

[0022] More preferably, the hinge axis is spaced apart from the rotation axes of the plurality of guide rollers, wherein the peeler includes a hinge member at the hinge axis, wherein a fixed arm is hingedly connected to the hinge member and rotatable about the hinge axis to engage the at least two guide rollers in a fixed state. Thus, the fixed arm can rotate about a component of the peeler not formed by the guide rollers. This component, in this case the hinge member, can be particularly adapted or modified for purposes facilitating rotation of the fixed arm and / or other functions related to fixing, as will be described in detail below.

[0023] In another embodiment, in the fixed state, the fixed arm is slotted onto at least two guide rollers in a locking direction parallel to the hinge axis, to a locked position, wherein the fixed arm can move from the locked position to an unlocked position spaced apart from the at least two guide rollers in a pulling direction opposite to the locking direction. Therefore, the fixed arm can be removed from the guide rollers to allow free rotation of the fixed arm and / or avoid collision with the guide rollers.

[0024] Preferably, the fixing member further includes a biasing member for biasing the fixing arm toward the locked position. Therefore, the fixing member can return to the locked position simply by releasing it from the unlocked position. Specifically, the fixing arm can be manually moved between the locked and unlocked positions by pulling and releasing. For example, the biasing member can be located at or within the hinge member.

[0025] In another embodiment, the peeler further includes an alignment member supported by a base member from a first side of the guide plane for aligning the fixed member in a fixed state, wherein the fixed member is configured to engage the alignment member when moved into the fixed state. The alignment member makes it easier for an operator to manually position the fixed member into the fixed state.

[0026] Preferably, the alignment member protrudes further from the base member in the axial direction than at least two guide rollers. The alignment member can align the fixing member before the fixing member engages the guide rollers.

[0027] Additionally or alternatively, the alignment member is at least partially conical. The conical portion of the alignment member can align and / or center the fixing member relative to the alignment member, even when the fixing member is slightly misaligned.

[0028] According to a second aspect, the present invention provides a stripping station including a stripper according to any embodiment of the first aspect of the present invention.

[0029] The various aspects and features described and illustrated in this specification may be applied individually in any possible circumstances. These individual aspects may become the subject of a divisional patent application. Attached Figure Description

[0036] Figure 6 It shows the method for using according to Figure 1 A front view of one or more reel sensors and a storage reel in the box; and

[0038] Figure 1 and 2 A stripping station 100 is shown for applying raw material 90 to a tire forming machine (not shown), such as a tire forming drum. The stripping station 100 is configured to receive a replaceable chuck or cassette 1 with a storage reel holder 11 for holding a storage 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, which is arranged to be positioned between the storage reel 81 and the liner reel 82 when the cassette 1 is received in the stripping station 100.

[0039] In this exemplary embodiment, the raw material 90 is formed from different parts, particularly a radio frequency identification (RFID) tag 91, which is stored in several loops on a storage reel 81, ready to be unwound and supplied to the tire forming machine via the stripping station 100. The RFID tag 91 may be embedded in a viscous elastomer material, preferably rubber, so that the RFID tag can be easily attached to the tire components. The loops are separated by one or more layers of pads 92 to prevent the raw material 90 in subsequent loops from adhering or sticking to each other. The pad reel 82 is used to collect the pads 92 when the raw material 90 is unwound. The pads 92 are guided along a pad path L from the storage reel 81 to the pad reel 82.

[0040] Optionally, the stripping station 100 and / or cassette 1 may have a scraper 115 located at scraping position C along the liner path L between the storage reel 81 and the stripper 2 to scrape off any raw material 90 accidentally adhered to the underside of the liner 92. It should be noted that scraping position C is positioned away from any other guiding means of the stripping station 100 and / or cassette 1. Specifically, at scraping position C, there is no guiding means forming an opposing surface directly opposite the scraper 115. Therefore, raw material 90 adhered to the upper side of the liner 92 can pass through scraping position C unimpeded.

[0041] like Figure 5A and 5BAs shown in more detail, the scraper 115 has a resiliently flexible scraping body 116, which is mounted to the stripping station 100 or box 1 at the location where the resiliently flexible scraping body 116 intersects with the pad path L where the pad 92 is absent, as shown by the dashed line. When the pad 92 is present at the pad path L, the resiliently flexible scraping body 116 presses against the pad 92 and / or deflects through the pad 92, as shown by the solid line. The scraping body 116 also has an acute-angled or sharp tip portion 117, i.e., a tip portion 117 with an acute angle or V-shaped profile, for effectively separating any raw material 90 accidentally adhered to the underside of the pad 92. The bending stress in the scraping body 116 ensures that the scraper 115 remains firmly pressed against the pad 92. Specifically, the scraping body 116 is chosen to be flexible enough 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 cuts 118, 119 may be configured to subtly weaken the scraping body 116 or promote bending of the scraping body 116 where it is intended to bend.

[0042] like Figure 3 and 4 As shown in the optimal configuration, 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 the guide plane P. The stripper 2 also includes an output roller 44 for discharging the raw material 90 after it has separated from the liner 92. The guide rollers 41, 42, 43 and the output roller 44 are rotatable about corresponding mutually parallel axes of rotation R1, R2, R3, R4, which extend in an axial direction X perpendicular to or substantially perpendicular to the guide plane P.

[0043] The peeler 2 is provided with a frame or base member 20 for supporting the pre-peeler plate 31, peeler plate 32 and a plurality of guide rollers 41, 42, 43 from the first side A of the guide plane P.

[0044] Pre-peeling plate 31 and peeler plate 32 extend on opposite sides of peeler groove S, which extends perpendicularly to guide plane P, for initially peeling the pad 92 and the raw material 90 apart as the raw material 90 traverses the peeler groove S. In other words, the pad 92 is peeled away from the raw material 90, or the raw material 90 is peeled away from the pad 92. Pre-peeling plate 31 defines a pre-peeling position in which the pad 92 is temporarily peeled away from the raw materials 90 and 91, or vice versa. Peeler plate 32 defines a re-engagement position in which the pad 92 is re-engaged to the raw material 90. The pre-peeling position and the re-engagement position are very close together, such that the raw material 90 loses support for only a very short time as it traverses the peeler groove S.

[0045] Guide rollers 41, 42, and 43 include a return roller 41 positioned below the peeler groove S along the pad path L for receiving the pad 92 from the pre-peel position and for returning the pad 92 to the re-engagement position. The return roller 41, together with the pre-peeler plate 31 and the peeler plate 32, defines a so-called "omega (Ω)" shaped portion of the pad path L.

[0046] The peeler groove 2 is typically located on the second side B of the guide plane P, opposite the first side A, and is used for manually inserting or placing the pad L between peeling operations.

[0047] like Figure 3 As best shown, the peeler 2 further includes a width adjustment member 7, which is positionable in the peeler groove S to adjust the width of the peeler groove S. Specifically, the width adjustment member 7 has an adjustment body 70 that defines a pre-peeling edge V1 on the side of the peeler groove facing the pre-peeler plate 31. The adjustment body 70 is adjustablely fastened to the pre-peeler plate 31, for example, by using elongated adjustment slots 71, 72. The width of the peeler groove S is preferably adjusted to at least 1.5 times or at least 2 times the thickness of the pad P2.

[0048] The peeler plate 32 has a wedge-shaped body that defines a peeling edge V2. The peeling edge V2 is relatively sharp or at an acute angle to effectively peel the liner 92 from the raw material 90.

[0049] The guide rollers 41, 42, and 43 also include one or more rear separating rollers 42 and 43 positioned downstream of the final peeling position along the liner path L, where the bushing 92 is permanently separated from the raw materials 90 and 91. The one or more rear separating rollers 42 and 43 guide the liner 92 toward the liner reel 82.

[0050] The output roller 44 is driven, actively driven, actively rotated, and / or driven to rotate about its axis of rotation R4 to ensure that the raw material 90 is pulled onto the output roller 44 and does not follow the pad 92 downstream of the final stripping position along the pad path L. In this example, the stripper 2 includes a transmission 21 between the output roller 44 and one of the guide rollers 42 of a plurality of guide rollers 41-43, the transmission 21 being used to drive the rotation of the output roller 44 by the rotation of said guide roller 42. In this case, the transmission 21 includes two meshing gears. Thus, the output roller 44 is driven in a direction of rotation opposite to that of the guide roller 42 connected to the output roller 44. Different types of mechanical transmissions, such as chains, belts, or the like, can be used, taking into account that the output roller 44 is connected to one of the guide rollers 41, 42, 43, to ensure the correct direction of rotation of said output roller 44. For example, a belt that drives two rollers 43, 44 in the same direction of rotation can be used to connect the output roller 44 to the final guide roller 43 on the pad path L.

[0051] In another alternative embodiment, the output tube 44 can be driven directly, for example, by a servo driver (not shown).

[0052] The transmission 21 is configured to drive the rotation of the output roller 44 at a certain transmission ratio with the rotation of the guide roller 42, resulting in the output roller 44 and the guide roller 42 having the same or substantially the same circumferential speed on their circumferential surfaces.

[0053] In this example, such as Figure 1 As shown, the output roller 44 is configured to support the raw material 90 on a pickup plane E1, which is parallel to or substantially parallel to a horizontal plane E2. More specifically, the pickup 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, such that the pickup plane E1 can be arranged with 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 pad 92, thus leaving the raw material 90 in the angled pickup plane E1, or it can rotate further until the raw material 90 is repositioned in or parallel to the horizontal plane E2.

[0054] 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.

[0055] like Figure 3 and 4 As further shown, the output roller 44 includes a roller body 48. In such a way... Figure 3 and 4 In the example shown, the roller body 48 is provided with a circumferential groove 45. The stripper 2 also includes a transmitter 22, a reflector 23, and a receiver 24, which are positioned such that a light beam, particularly 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 may alternatively be positioned to reflect the light beam in a direction different from the direction in which it is received, in which case at least one of the incident or outgoing beams extends along the aforementioned line of sight M. The transmitter 22 and the receiver 24 may be integral as shown, or separate components. In another alternative embodiment, only a transmitter and receiver, such as a backlight, may be used on opposite sides of the output roller 44, or the reflector 23 may be replaced by a reflective portion of the raw material 90, making the raw material 90 sufficiently reflective.

[0056] 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 groove 45, the height of the circumferentially extending ribs is significantly less than the depth of the circumferential groove 45, i.e., less than 20% or less than 10% of the depth.

[0057] 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 onto the tire component 109. The pick-and-place fixture 200 may be rotatable about a reorientation axis K to change the orientation of the raw material 90 relative to the tire component 9 before placement. Alternatively, the output roller 44 may be rotatable about a vertical reorientation axis K for the same purpose.

[0058] like Figure 1 As shown in Figure 4, the peeler 2 includes a fixing member 6, which can be positioned as follows: Figure 1 and 3 The open state shown is the same as... Figure 2 and 4The device moves between the shown fixed states. In the open state, the fixing member 6 facilitates convenient, free, or unobstructed access to the pad path L and / or insertion or placement of the length of the pad 92 from the second side B into the pad path L. In the fixed state, the fixing member 6 is arranged, configured, or adapted to fix, secure, connect, interconnect, and / or fix at least two of the plurality of guide rollers 41, 42, 43 relative to each other in one or more fixing directions D parallel to the guide plane of the second side B. The fixing direction D may be different for each pair of guide rollers 41, 42, 43. In particular, the fixing direction D is parallel to the line that connects the fixed pairs of guide rollers 41, 42, 43 to each other.

[0059] In this example, the fixing member 6 fixes one of the return roller 41, the rear separation roller 42, and the output roller 44.

[0060] The fixing component 6 includes a fixing bracket, finger-like members, or a wall 60, which is interconnected with the aforementioned rollers 41, 42, and 44. The fixing arm 60 can be positioned as follows: Figure 1 and 3 The open state shown is the same as... Figure 2 and 4 The fixed states shown are hinged about a hinge axis H perpendicular to the guide plane P. The hinge axis H is spaced apart from the rotation axes R1, R2, R3 of the plurality of guide rollers 41, 42, 43. The peeler 2 includes a shaft or hinge member 40 at the hinge axis H, spaced apart from and / or not from 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 may be connected to one of the guide rollers 41, 42, 43 and the output roller 44.

[0061] The peeler 2 also includes 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 further from the base member 20 in the axial direction X than the guide rollers 41, 42, 43 and the output roller 44. Specifically, the alignment member 46 has a conical portion 47 that protrudes towards or faces the fixing member 6 at a second side B. The fixing member 6 is configured to engage the alignment member 46 when moved to the fixed state.

[0062] Alternatively, the fixing member 6 may be linearly movable, i.e., sliding it into or out of the fixed state, or it may be detachably installed in the fixed state and separated from the peeler 2 in the open state.

[0063] like Figure 3 and 4 As shown, the fixed arm 60 has an arm body with a plurality of grooves, openings, or positioning portions 61-64 for positioning and / or slotting over the guide rollers 41, 42, output roller 44, and / or alignment member 46 from the second side B of the peeler 2 in a locking direction F parallel to the hinge axis H. The positioning portions 61-64 may be at least partially slotted over the distal ends of the respective rollers 41, 42, 44, and / or alignment member 46, more particularly over the bearing portion provided at the respective distal end, or, for the alignment member 46, over its conical portion 47.

[0064] To achieve slotted movement, in addition to rotating about the hinge axis H, the fixed arm 60 is given another degree of freedom of movement. Specifically, the fixed arm 60 can move in the pulling direction G, opposite to the locking direction F. Figure 4 The locked position shown is moved to the position shown. Figure 3 In the unlocked position shown, it is spaced apart from at least two guide rollers 41, 42.

[0065] In this example, the fixing member 6 also includes a biasing member 65 for biasing the fixing arm 60 toward the locked position. More specifically, the biasing member 65 is a spring disposed in or at the hinge member 40. Therefore, the fixing arm 60 can be pulled and released as... Figure 4 The locking position shown is the same as... Figure 3 Manually move between the unlocked positions shown.

[0066] like Figure 1 and 6 As shown, the cassette 1 or stripping station 100 is equipped with a first reel sensor 301 and a second reel sensor 302 for detecting the state of the storage reel 81. Specifically, 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 the presence of the storage reel 81 in the cassette 1 or stripping station 100. For this purpose, the first reel sensor 301 is configured to emit a beam, such as a laser beam, closely along the hub 80 of the storage reel 81 but not intersecting it. The second reel sensor 302 is configured to emit a beam, such as a laser beam, intersecting the hub 80 of the storage reel 81. The cassette 1 or stripping station 100 is also provided with a reflector 303 for returning the beam to the corresponding reel sensors 301, 302.

[0067] Specifically, the first reel sensor 301 receives its beam returned from the reflector 303 only when the storage reel is empty or nearly empty. In other words, the raw materials 90, 91, and the pad 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 storage reel 81 is removed from the cassette 1 or the stripping station 100. In other words, the hub 80 no longer blocks the beam of the second reel sensor 302.

[0068] In practice, the gasket 92 may have irregularities that could at least partially scatter the beam back to the corresponding reel sensors 301, 302. Such irregularities may be formed by circumferential bulges, indentations, or variations in the gasket 92, primarily due to the intermittent presence of the raw materials 90, 91 at different locations along the circumference of the gasket 92 and in different loops of the gasket surrounding the hub 80 of the storage reel 81. This scattering is unpredictable and may result in false positive detection signals at the corresponding reel sensors 301, 302, such as a false positive detection showing the storage reel 81 as empty when it is not, or a false positive detection when the storage reel 81 has been removed.

[0069] To minimize or prevent false positive detection results, it has been found advantageous to position the reel sensors 301 and 302 at tilted beam angles T1, T2, and T3 relative to the vertical planes W1 and W2. Specifically, the reel sensors 301 and 302 can be positioned as follows: Figure 1 The ground shown is oriented at an oblique angle relative to the vertical plane W1 parallel to the axis N of the storage reel, or as... Figure 6 The beam is oriented at an angle relative to a vertical plane W2 perpendicular to the axis N of the storage reel, or at an angle relative to both vertical planes W1 and W2. The tilt 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 tilt angles, the liner 92 is less likely to return a false positive.

[0070] Now refer to Figure 1 -4 clarifies the method for using the aforementioned peeler 2 to peel the pad 92 from the raw material 90, and in particular from the radio frequency identification tag 91.

[0071] Figure 1 and 3 The fixing member 6 is shown, which has been removed from its such Figure 2 and 4After the corresponding fixed state is moved to its corresponding 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 peeler 2 is freely accessible along its entire length, at least within the peeler 2. As a result, a new length of liner 92 can be manually inserted or placed in and / or guided or passed through the liner path L, for example, when preparing a new box 1 or inserting a new box 1 into the peeling station 100 before the peeling operation.

[0072] Figure 2 and 4 This shows how the fixing member 6 has subsequently been removed from it, as shown in the image. Figure 1 and 3 The corresponding open state shown moves back to its corresponding fixed state. The fixing component 6 rigidly connects at least two guide rollers 41, 42 to each other, thereby providing more accurate guidance of the pad 92 despite the force applied to the corresponding part of the peeler 2 through the pad 92.

[0073] As previously mentioned, the output roller 44 is driven. Therefore, when the material 90, specifically the RFID tag 91, separates from the pad 92 at the final peel position, the output roller 44 can pull the material 90 completely onto the output roller 44. As a result, the material 90 is no longer supported by the pad 92 and / or is completely separated from the pad 92.

[0074] The raw material 90 remains stationary on the output roller 44 for subsequent pickup by the pick-up and placement fixture 200.

[0075] It is understood that the above description illustrating the preferred embodiments is intended not to limit the scope of the present invention. Many variations will be apparent to those skilled in the art from the foregoing discussion, and these variations are also included within the scope of the present invention.
