Description

Technical Field

[0001] The present invention relates to a pasting device, a pasting system, a pasting method and a tire for pasting an annular member to the inner peripheral surface of a tire. Background Art

[0002] To absorb and mitigate resonant acoustic energy (vibration energy) generated within the tire's inner cavity, suppress cavity resonance, and reduce road noise, a porous sponge material is sometimes attached to the tire's inner circumference. Patent Document 1 below discloses a tire manufacturing device that attaches a sponge material (sound-absorbing material) to the tire's inner circumference.

[0003] The manufacturing device includes multiple inscribed shafts arranged at equal intervals on a circumference having the same diameter as the inner circumference of the tire. A long strip of sponge material is wound around the outer sides of these inscribed shafts to form the sponge material into a ring shape. The manufacturing device moves each inscribed shaft radially inward to shrink the outer diameter of the ring-shaped sponge material (hereinafter referred to as the "annular member"). After inserting the annular member into the tire, the inscribed shafts are moved radially outward to partially adhere the annular member to the inner circumference of the tire. Furthermore, the manufacturing device adheres the entire annular member to the inner circumference of the tire by moving (rotating) the multiple inscribed shafts along the inner circumference of the tire.

[0004] Patent Document 1: Japanese Patent Application Laid-Open No. 2008-254338 Summary of the Invention

[0005] In the manufacturing device described in Patent Document 1, when the annular component is inserted into the tire and multiple inscribed shafts are moved radially outward, the annular component is partially bonded to the tire's inner circumferential surface at multiple locations spaced circumferentially by each inscribed shaft. Adjacent bonded locations are left floating from the tire's inner circumferential surface. If the multiple inscribed shafts are moved along the tire's inner circumferential surface in this state, the annular component that is floating from the inner circumferential surface is circumferentially pressed by the inscribed shafts, easily causing wrinkles in the annular component. Consequently, it is difficult to evenly bond the entire annular component to the tire's inner circumferential surface.

[0006] An object of the present invention is to uniformly adhere an annular member to the inner peripheral surface of a tire.

[0007] (1) The present invention is a sticking device for sticking an annular member to the inner circumferential surface of a tire, wherein the sticking device comprises: a plurality of retainers arranged at intervals in a circumferential direction around a predetermined axis, for retaining the inner circumferential surface of the annular member;

[0008] a moving mechanism that moves the plurality of retaining members in a radial direction centered on the axis;

[0009] a rotating mechanism that moves the plurality of retaining members in the circumferential direction; and

[0010] control device,

[0011] The control device controls the operations of the holder, the moving mechanism, and the rotating mechanism to perform the following operations (a) to (f).

[0012] (a) holding the inner circumferential surface of the annular member by the retaining member;

[0013] (b) moving the holder holding the annular member outward in the radial direction toward a predetermined attachment position to attach a portion of the annular member to the inner circumferential surface of the tire;

[0014] (c) releasing the retaining member from retaining the annular member;

[0015] (d) moving the retainer to a retracted position radially inward of the attachment position to separate the retainer from the annular member;

[0016] (e) moving the retaining member in the circumferential direction; and

[0017] (f) The retainer is moved to the attachment position, and the other portion of the annular member is attached to the inner peripheral surface of the tire.

[0018] According to the above structure, the attachment device attaches a portion of the annular component to the inner circumferential surface of the tire using a plurality of retainers, temporarily separates the retainers from the annular component, and then shifts the circumferential position of the retainers to attach another portion of the annular component to the inner circumferential surface of the tire. Thus, the substantially entire annular component can be evenly attached to the inner circumferential surface of the tire without causing wrinkles on the annular component.

[0019] (2) Preferably, the control device controls the operation of the rotating mechanism after the operation (f) so that the retainer moves in the circumferential direction while the retainer presses the annular member against the inner circumferential surface of the tire.

[0020] With such a structure, the annular member can be attached without being lifted from the inner peripheral surface of the tire over the entire circumference.

[0021] (3) Preferably, the holder includes a holding member that holds the annular member and a roller that can roll on the inner peripheral surface of the annular member.

[0022] According to this configuration, when the holder is moved in the circumferential direction while the holder is pressing the annular member against the inner circumferential surface of the tire, the roller can roll on the inner circumferential surface of the annular member, thereby reducing the movement resistance of the holder.

[0023] (4) Preferably, the retreat position includes a first retreat position in which the annular component held by the retaining member is contracted to a position smaller than the inner diameter of the tire, and a second retreat position radially located between the first retreat position and the pasting position in which the retaining member is separated from the annular component pasted to the inner circumferential surface of the tire.

[0024] This structure can shorten the cycle time from the operation (b) of attaching a portion of the annular member to the inner circumferential surface of the tire to the operation (f) of moving the holder circumferentially to attach another portion of the annular member to the inner circumferential surface of the tire.

[0025] (5) Preferably, the moving mechanism has a pair of connecting rod mechanisms, each of which has a cylinder body arranged on the axis and extending and retracting in the axial direction along the axis, and a connecting rod part connected to the cylinder body at one end and to the retaining member at the other end, and the pair of connecting rod mechanisms are arranged on both sides of the axial direction of the retaining member.

[0026] According to this structure, the retainer can be moved radially without changing its axial position by extending and contracting the cylinders in the pair of link mechanisms. Therefore, when the retainer is moved from the retracted position to the attachment position, the retainer can be smoothly moved toward the inner circumference of the tire.

[0027] (6) The present invention is a system for attaching an annular member to the inner circumferential surface of a tire, the system comprising:

[0028] A pasting device that shapes the long strip-shaped member into an annular member and adheres the annular member to the inner circumferential surface of the tire;

[0029] a first feeding device that feeds the long strip-shaped member to the attaching device; and

[0030] A second supply device supplies the tire to the attaching device.

[0031] With such a configuration, the operations from molding the annular member to attaching the annular member to the tire can be performed consistently.

[0032] (7) Preferably, the attaching device and the second supply device are arranged adjacent to each other in a first direction along the axial direction of the annular member formed by the attaching device.

[0033] The attaching device and the first supply device are arranged adjacent to each other along a second direction orthogonal to the first direction.

[0034] With such a configuration, the operator can smoothly move between the first supply device and the applying device, and between the applying device and the second supply device.

[0035] (8) The present invention is a method for attaching an annular member to the inner circumferential surface of a tire, comprising the following steps (a) to (f).

[0036] (a) holding the inner circumferential surface of the annular member by a plurality of retainers arranged at intervals in a circumferential direction around a predetermined axis;

[0037] (b) moving the holder holding the annular member outward in the radial direction with the axis as the center toward a predetermined attachment position to attach a portion of the annular member to the inner circumferential surface of the tire;

[0038] (c) releasing the retaining member from retaining the annular member;

[0039] (d) moving the retainer to a retracted position radially inward of the attachment position to separate the retainer from the annular member;

[0040] (e) moving the retaining member in the circumferential direction; and

[0041] (f) The retainer is moved to the attachment position, and the other portion of the annular member is attached to the inner peripheral surface of the tire.

[0042] According to the above-described attachment method, a portion of the annular component is attached to the inner circumferential surface of the tire using multiple retainers. After the retainers are temporarily separated from the annular component, the circumferential positions of the retainers are shifted and another portion of the annular component is attached to the inner circumferential surface of the tire again. Thus, the substantially entire annular component can be evenly attached to the inner circumferential surface of the tire without causing wrinkles on the annular component.

[0043] (9) Preferably, the pasting method further includes, after the step (f), the step of moving the retainer in the circumferential direction while the annular member is pressed against the inner circumferential surface of the tire by the retainer.

[0044] With such a structure, the entire annular member can be attached without being lifted from the inner peripheral surface of the tire.

[0045] (10) Preferably, the pasting method further comprises the following step before the step (b): applying a sealing material for bonding the annular component to the inner circumferential surface of the tire.

[0046] With this structure, the annular member can be attached to the inner peripheral surface of the tire using a sealant for preventing tire rupture as an adhesive.

[0047] (11) The tire of the present invention includes a sealing material provided on the inner peripheral surface and an annular member provided radially inside the sealing material.

[0048] With such a configuration, the annular member can be adhered to the inner peripheral surface of the tire using a sealant for preventing tire rupture as an adhesive.

[0049] According to the present invention, the annular member can be evenly bonded to the inner peripheral surface of the tire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0069] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0070] Tire structure

[0071] Figure 1 It is a cross-sectional view showing an example of a tire.

[0072] exist Figure 1 In the figure, tire 1 comprises a tread 2, a pair of sidewalls 3, a pair of beads 4, a carcass 5, a belt 6, an inner liner 7, and the like. The tread 2 is made of cross-linked rubber, and its outer surface contacts the road surface. The pair of sidewalls 3 are also made of cross-linked rubber and extend radially inward from both ends of the tread 2. The beads 4 are radially inward of the sidewalls 3 and have a core 4a and an apex rubber 4b.

[0073] The carcass 5 is located on the inner side of the tread 2 and the sidewall 3 and is spanned between the bead 4 on one side and the bead 4 on the other side. The belt layer 6 is located between the tread 2 and the carcass 5. The inner liner 7 is located on the inner side of the carcass 5. The inner liner 7 is made of a cross-linked rubber with excellent air barrier properties and constitutes the inner surface of the tire 1. In addition, in this specification, the "inner circumferential surface 1a of the tire 1" refers to the inner circumferential surface of the inner liner 7 on the radial inner side of the tread 2. The "inner diameter of the tire 1" refers to the inner diameter of the bead 4 (the inner diameter of the bead).

[0074] An annular component 10 is attached to the inner circumferential surface 1a of the tire 1. The annular component 10 is formed into an annular shape by joining the two ends of a long strip of sponge material. The sponge material is formed from a porous material having continuous or independent bubbles formed by foaming rubber or synthetic resin. The sponge material has vibration-proof or sound-absorbing properties, and by absorbing and mitigating the resonant sound energy (vibration energy) generated inside the tire 1, it suppresses cavity resonance and reduces road noise. Hereinafter, the long strip of sponge material formed into an annular shape will also be referred to as a "long strip-shaped component."

[0075]

Structure of the pasting system

[0076] Figure 2 This is a schematic plan view of a system 20 for attaching a long strip-shaped member 11 according to one embodiment of the present invention.

[0077] The pasting system 20 of this embodiment includes a pasting device 23, a first supply device 21, a second supply device 22, and a control device 24. The pasting device 23 has the function of forming the long strip-shaped component 11 into a ring shape (forming function of the ring-shaped component 10) and the function of pasting the ring-shaped ring-shaped component 10 to the inner circumferential surface 1a of the tire 1 (pasting function). Therefore, in the following description, the pasting device 23 is sometimes referred to as the "forming device 23." The first supply device 21 supplies the long strip-shaped component 11 to the pasting device 23. The second supply device 22 supplies the tire 1 to the pasting device 23.

[0078] The control device 24 controls the operation of the applying device 23, the first supply device 21, and the second supply device 22. The control device 24 includes, for example, a computing unit such as a CPU and a storage unit such as RAM and ROM. The computing unit executes programs stored in the storage unit to perform its functions. The control device 24 receives input signals from various sensors and switches, and based on these input signals, controls the operation of motors and actuators provided in the applying device 23, the first supply device 21, the second supply device 22, and the like.

[0079] The attaching device 23 and the second supply device 22 are arranged adjacent to each other along a horizontal first direction X. The attaching device 23 is arranged so that the axis (center) of the annular component 10 formed by the attaching device 23 is along the first direction X. The second supply device 22 is arranged so that the axis of the tire 1 supported by the second supply device 22 is along the first direction X. The axis of the annular component 10 formed by the attaching device 23 coincides with the axis of the tire 1 supported by the second supply device 22. Hereinafter, these axes are denoted by the symbol C1.

[0080] The attaching device 23 and the first supply device 21 are arranged adjacent to each other along a horizontal second direction Y. The second direction Y is perpendicular to the first direction X. The first supply device 21 supports the long strip-shaped member 11 so that its longitudinal direction is along the second direction Y, and supplies the long strip-shaped member 11 along the second direction Y toward the attaching device 23.

[0081] [First supply device 21]

[0082] Figure 3 It is a side view showing the first supply device 21 and the sticking device 23 in the sticking system 20.

[0083] like Figure 2 and Figure 3 As shown, the first supply device 21 is composed of a roller conveyor arranged horizontally along the second direction Y. The roller 21a of the first supply device 21 is composed of a free roller, which pulls the long strip-shaped component 11 through the retaining member 31 of the pasting device 23 described later, and supplies the long strip-shaped component 11 on the first supply device 21 to the pasting device 23. The first supply device 21 is arranged at a height corresponding to the uppermost retaining member 31 described later. The roller 21a of the first supply device 21 can also be composed of a driving roller, or a combination of a free roller and a driving roller. In this case, the first supply device 21 itself can move the long strip-shaped component 11 toward the pasting device 23. The first supply device 21 can also be composed of a belt conveyor. The first supply device 21 can also be composed of a reel around which the long strip-shaped component 11 is wound.

[0084]

Pasting device 23

[0085] Figure 4 and Figure 5 (a) is a top view of the pasting device 23, Figure 4 and Figure 5 (b) is a side view of the pasting device 23.

[0086] like Figures 3 to 5As shown, the attaching device 23 includes a plurality of holders 31 , a moving mechanism 32 , a rotating mechanism 33 , and a pressing mechanism 34 . The plurality of holders 31 are arranged at equal intervals around an axis C1 along the first direction X. The attaching device 23 of this embodiment includes eight holders 31 .

[0087] (Holding member 31)

[0088] Figure 6 It is a perspective view of the holder 31 . Figure 7 It is a schematic front view of the holder 31.

[0089] Each holder 31 includes a holding member 36 , rollers 37 a and 37 b , and a support frame 38 .

[0090] The holding member 36 holds one surface (the lower surface) of the elongated strip-shaped member 11 or the inner circumferential surface of the annular member 10. The holding member 36 in this embodiment comprises a housing 36a and a plurality of needles 36b disposed within the housing 36a so as to be freely movable. The housing 36a is formed into a rectangular box shape and is supported by a support frame 38. An actuator (not shown) such as a cylinder is incorporated within the housing 36a to move the needles 36b forward and backward.

[0091] Each needle 36b protrudes from the upper surface (holding surface) 36a1 of the shell 36a and can retreat to the bottom of the upper surface 36a1. The multiple needles 36b are arranged in two rows along the first direction X. The multiple needles 36b in each row are set in a posture inclined in the same direction relative to the holding surface 36a1 of the shell 36a. The needles 36b in one row and the needles 36b in the other row are inclined in opposite directions to each other, intersecting with the protrusions retreated in the shell 36a, and moving away from each other when protruding from the shell 36a. The holding component 36 holds the long strip-shaped component 11 by inserting the needles 36b at an angle relative to the long strip-shaped component 11. Since the holding component 36 holds the long strip-shaped component 11 by inserting the needles 36b, it can be held even for sponge materials that cannot use vacuum-type holders. As the holding member 36 , a known device such as a needle holder (SNG-M) manufactured by Schmults can be applied.

[0092] The rollers 37a and 37b include a first roller 37a and a second roller 37b. The first rollers 37a are arranged adjacent to both sides of the housing 36a in the first direction X. Two first rollers 37a are provided on each side of the holding member 36 in the first direction X. The first rollers 37a are rotatably mounted on the support frame 38 about an axis extending along the first direction X.

[0093] The second rollers 37b are arranged on both sides of the housing 36a in a direction perpendicular to the first direction X. The second rollers 37b are rotatably mounted on the support frame 38 about an axis extending along the first direction X. The second rollers 37b are formed to be longer than the first rollers 37a in the first direction X. Specifically, the second rollers 37b have a length in the first direction X that spans the holding member 36 and the first rollers 37a. As described above, the holding member 36 is surrounded by the first rollers 37a and the second rollers 37b.

[0094] As will be described later, the first roller 37a and the second roller 37b roll on the inner circumferential surface of the annular member 10 attached to the inner circumferential surface 1a of the tire 1. The first roller 37a and the second roller 37b protrude beyond the holding surface 36a1 of the holding member 36. Therefore, the first roller 37a and the second roller 37b can roll on the inner circumferential surface of the annular member 10 without the holding surface 36a1 contacting the inner circumferential surface of the annular member 10.

[0095] (Moving mechanism 32)

[0096] like Figures 3 to 5 As shown, the moving mechanism 32 includes a pair of link mechanisms 40 and a support frame 41 that supports the pair of link mechanisms 40. The pair of link mechanisms 40 are arranged on both sides of the holder 31 in the first direction X. Each link mechanism 40 includes a cylinder 42 and a link member 43. The cylinder 42 may be formed of an electric cylinder, a fluid pressure cylinder, or the like. The cylinder 42 is arranged along the first direction X and extends and retracts in the same direction X. The main body of the cylinder 42 is fixed to the support frame 41. The rod portion of the cylinder 42 is movable in the first direction X. The distal end 42a of the rod portion is guided by a guide 41a provided on the support frame 41.

[0097] The link member 43 includes a first link member 43a, one end of which is rotatably connected to the terminal end 42a of the cylinder 42. The other end of the first link member 43a is rotatably connected to one end of a second link member 43b. The other end of the second link member 43b is fixed to the holder 31.

[0098] In the first direction X, the link mechanism 40 disposed on one side of the holder 31 and the link mechanism 40 disposed on the other side are symmetrically disposed with respect to the center line O of the holder 31 in the first direction X. The cylinders 42 of the pair of link mechanisms 40 extend and retract synchronously. When the two cylinders 42 extend, as shown in FIG. Figure 4 As shown, each retaining member 31 moves radially outward. When the two cylinder bodies 42 contract, as shown in FIG. Figure 5 As shown in FIG. 1 , each retainer 31 moves radially inward. At this time, the retainer 31 moves radially without changing its position in the first direction X.

[0099] Below, we will Figure 4The position of the retaining member 31 shown is also referred to as the "molding position" or "sticking position". Figure 5 The position of the holder 31 shown is also referred to as a “first retracted position.” As will be described later, the moving mechanism 32 of this embodiment can position the holder 31 at a “second retracted position” between the molding position and the first retracted position.

[0100] In addition, the cylinder 42 in the connecting rod mechanism 40 may also adopt a structure in which the main part of the cylinder 42 is arranged in the support frame 41, and the rod part protrudes axially outward from the main part. However, in this case, space is required in the support frame 41 to accommodate the main part of the cylinder 42, and the outer diameter of the support frame 41 becomes larger accordingly. Therefore, as described later, it becomes difficult to insert the annular component 10 into the interior of the tire 1, and in particular, it may not be applicable to tires 1 with small diameters. Therefore, as in the present embodiment, it is preferable to adopt a structure in which the main part of the cylinder 42 is arranged axially outside the support frame 41, and the rod part protrudes axially inward (toward the retaining member 31) from the main part, in order to miniaturize the support frame 41.

[0101] (Rotation mechanism 33)

[0102] like Figures 3 to 5 As shown, the rotating mechanism 33 rotates the holder 31 and the moving mechanism 32 about the axis C1. The rotating mechanism 33 includes a housing 33a that rotatably supports the support frame 41 of the moving mechanism 32. A drive unit such as a motor or a power transmission mechanism for rotating the support frame 41 is provided within the housing 33a.

[0103] (Pressing mechanism 34)

[0104] like Figure 3 As shown, the pressing mechanism 34 is arranged above the retaining member 31 arranged at the uppermost position. The pressing mechanism 34 includes a pressing component 34a and an actuator 34b. The pressing component 34a is composed of, for example, a roller that rotates around an axis along the first direction X. The actuator 34b is composed of a cylinder that can be extended and retracted in the up and down directions. As the cylinder, a fluid pressure cylinder or an electric cylinder can be used. The pressing component 34a is provided at the lower end of the actuator 34b and moves up and down by the extension and retraction of the actuator 34b. When moving downward, the pressing component 34a presses the long strip-shaped component 11 arranged on the retaining member 31 arranged at the uppermost position from above.

[0105] [Molding sequence of the annular member 10]

[0106] Figure 8 It is an explanatory diagram showing the procedure of molding the annular member 10 .

[0107] Hereinafter, the procedure for molding the annular member 10 using the first supply device 21 and the attaching device 23 will be described. The operation of the attaching device 23 described below is performed under the control of the control device 24.

[0108] To form the annular member 10, first, Figure 8 As shown in (a), the operator pulls the long strip-shaped member 11 on the first supply device 21 toward the pasting device 23, and positions the end portion 11a of the long strip-shaped member 11 on the uppermost holder 31 at the molding position. Then, the pressing member 34a of the pressing mechanism 34 presses the end portion 11a of the long strip-shaped member 11 on the holder 31, so that the needle 36b of the holder 36 (see FIG. 3 ) is pressed against the holder 31. Figure 7 ) protrudes and pierces the long strip-shaped member 11. As a result, the terminal end 11a of the long strip-shaped member 11 is held by the uppermost holding member 31.

[0109] Then, if Figure 8 As shown in (b), the rotating mechanism 33 of the attaching device 23 rotates the multiple retainers 31 in the direction of arrow a, with the uppermost retainer 31 sequentially retaining the long strip-like member 11. Furthermore, each time a retainer 31 reaches its uppermost position, the rotating mechanism 33 temporarily stops. While the rotating mechanism 33 is stopped, the retainer 31 protrudes the needle 36b of the retaining member 36, piercing the needle 36b into the long strip-like member 11. Thus, the retainer 31 can stably retain the long strip-like member 11.

[0110] The pressing mechanism 34 raises and retracts the pressing member 34a except when the terminal portion 11a of the long strip-like member 11 is held by the retaining member 31. This is because, by wrapping the long strip-like member 11 around the outer peripheries of the plurality of retaining members 31, the long strip-like member 11 is naturally pressed against the uppermost retaining member 31. However, the pressing member 34a may be lowered to press the long strip-like member 11 each time each retaining member 31 is in the uppermost position.

[0111] like Figure 8 As shown in (c), when the holder 31 that was initially in the uppermost position is again in the uppermost position, the terminal end 11b of the long strip-shaped member 11 is placed on the holder 31. The operator joins the terminal end 11a and the terminal end 11b of the long strip-shaped member 11 with an adhesive, thereby forming the long strip-shaped member 11 into the ring-shaped member 10.

[0112] After the annular member 10 is formed, the moving mechanism 32 moves the plurality of retainers 31 to the first retracted position in the radial direction inward (see Figure 5 ). As a result, the annular member 10 shrinks, and its outer diameter shrinks to be smaller than the inner diameter of the tire 1, and becomes a shape that can be inserted into the tire 1.

[0113] Figure 9 It is an explanatory diagram showing a joining portion of the annular member 10 .

[0114] The end portion 11a and the terminal portion 11b of the long strip-shaped member 11 can be formed as Figure 9 The shape shown. Figure 9 In the example shown in (a), a plurality of recesses 11c are formed on one side of the distal end 11a and the terminal end 11b of the long strip-shaped member 11, and a plurality of protrusions 11d are formed on the other side. The plurality of recesses 11c are of the same shape, and the plurality of protrusions 11d are of the same shape. The recesses 11c and protrusions 11d formed on the distal end 11a and the terminal end 11b of the long strip-shaped member 11 fit together.

[0115] By fitting the recessed portion 11c and the convex portion 11d together, the axial (first direction X) positional offset of the terminal portion 11a and the terminal end portion 11b of the long strip-shaped component 11 can be suppressed. In addition, the side surfaces on both axial sides of each recessed portion 11c and the side surfaces on both axial sides of each convex portion 11d are inclined relative to the circumferential direction. When fitting the recessed portion 11c and the convex portion 11d together, by bringing their axial side surfaces into contact with each other, the terminal portion 11a and the terminal end portion 11b of the long strip-shaped component 11 can be suppressed from separating in the circumferential direction. The recessed portion 11c and the convex portion 11d are curved as a whole and do not have any angular parts. Therefore, stress concentration is difficult to occur, and damage to the recessed portion 11c and the convex portion 11d can be suppressed. Furthermore, by forming the concave portion 11c and the convex portion 11d at the end portion 11a and the terminal portion 11b of the long strip-shaped member 11, the bonding area between the end portion 11a and the terminal portion 11b can be increased, and the end portion 11a and the terminal portion 11b can be bonded more firmly.

[0116] exist Figure 9 In the example shown in (b), a recess 11c is formed on one side of the end portion 11a and the terminal portion 11b of the long strip-shaped part 11, and a protrusion 11d is formed on the other side. The axial side surfaces of the recess 11c and the axial side surfaces of the protrusion 11d are inclined relative to the circumferential direction. When the recess 11c and the protrusion 11d are fitted together, the axial positional deviation and circumferential separation of the end portion 11a and the terminal portion 11b are suppressed by making their axial side surfaces contact each other. The structure of the recess 11c and the protrusion 11d in this example is relatively Figure 9 The structure shown in (a) is simple, but the bonding area is slightly small. In addition, the outer shape of the concave portion 11c and the convex portion 11d is formed by a combination of straight lines, and the shape changes sharply, so it is easy to cause damage caused by stress concentration. Therefore, in these aspects, Figure 9 The example shown in (a) is more advantageous.

[0117] exist Figure 9In the example shown in (c), a recess 11c is formed on one side of the terminal portion 11a and the terminal end portion 11b of the long strip-shaped component 11, and a protrusion 11d is formed on the other side. The axial side surfaces of the recess 11c and the axial side surfaces of the protrusion 11d are arranged along the circumferential direction. When the recess 11c and the protrusion 11d are fitted together, the axial positional deviation is suppressed by making their axial side surfaces contact each other. However, it is impossible to suppress the terminal portion 11a and the terminal end portion 11b from separating in the circumferential direction. In addition, the recess 11c and the protrusion 11d of this example are Figure 9 The concave and convex parts shown in (b) are similar in structure, but the bonding area is slightly smaller and the shape changes rapidly, so it is easy to cause damage caused by stress concentration. Therefore, in these aspects, Figure 9 The example shown in (a) is more advantageous.

[0118] Second supply device 22

[0119] Figure 10 This is a schematic cross-sectional view of the second supply device 22 as viewed from the front side.

[0120] like Figure 2 and Figure 10 As shown, the second supply device 22 includes a base member 51, a movable frame 52, and a gripping mechanism 53. The base member 51 is provided with a first guide rail 51a extending in the first direction X. The movable frame 52 moves along the first guide rail 51a of the base member 51. The movable frame 52 is driven by a drive unit (not shown). The movable frame 52 is provided with a second guide rail 52a extending in the first direction X.

[0121] The holding mechanism 53 includes a pair of movable platforms 54, a coupling 55 connecting the pair of movable platforms 54, and a driving unit 56. The pair of movable platforms 54 move along the second guide rail 52a. The coupling 55 includes a threaded shaft 55a extending along the first direction X. The threaded shaft 55a is driven by the driving unit 56 (see FIG. 1 ) which is composed of a motor or a belt transmission mechanism. Figure 2 ) is driven to rotate. Threads that become reverse threads are formed on both sides of the screw shaft 55a in the axial direction, and each thread is screwed into a pair of moving tables 54 respectively.

[0122] When the threaded shaft 55 a rotates in one direction, the pair of movable stages 54 move toward each other, and when the threaded shaft 55 a rotates in the other direction, the pair of movable stages 54 move away from each other.

[0123] The gripping mechanism 53 includes gripping frames 57, each mounted on a pair of movable stages 54. An opening 57a is formed in the center of the gripping frame 57. A plurality of gripping members 58 are arranged on the gripping frame 57 at intervals around an axis C1 extending along the first direction X. Each gripping member 58 is mounted on the gripping frame 57 so as to be movable radially about the axis C1. Each gripping member 58 is moved radially by a drive unit 59, such as a fluid pressure cylinder, to move closer to or farther from each other. Each gripping member 58 includes a claw 58a protruding in the first direction X, which grips the tire 1.

[0124] A mounting platform 60 for mounting the tire 1 is provided on the movable frame 52 of the second supply device 22. The pair of movable platforms 54 of the gripping mechanism 53 move toward or away from the tire 1 mounted on the mounting platform 60. The gripping members 58 of the gripping mechanism 53 are inserted into the tire 1 mounted on the mounting platform 60 to grip the tire 1.

[0125] [Attachment order of the ring-shaped component 10]

[0126] (Basic order)

[0127] Next, a basic procedure of attaching the annular member 10 to the tire 1 will be described in detail. In the following description, the operations of the second supply device 22 and the attaching device 23 are controlled by the control device 24.

[0128] Figure 11 This is an explanatory diagram showing the procedure of setting the tire 1 on the second supply device 22 as seen from the top side. Figure 12 and Figure 13 It is an explanatory diagram showing the procedure of attaching the annular member 10 to the tire 1 as seen from the top side.

[0129] First, before the annular member 10 is attached to the tire 1, the tire 1 is placed on the second supply device 22. Specifically, Figure 2 As shown, the pasting system 20 has a preparation table 25 near the second supply device 22. The tire 1 with the adhesive applied to the inner peripheral surface 1a is prepared on the preparation table 25. The operator moves the tire 1 from the preparation table 25 to the mounting table 60 of the second supply device 22 at a position A3 between the preparation table 25 and the second supply device 22, and places the tire 1 on the mounting table 60 (see FIG. Figure 11 (a)).

[0130] Then, if Figure 11 As shown in FIG. 2( b ), the pair of movable stages 54 of the second supply device 22 move toward each other, and the plurality of gripping members 58 are inserted into the tire 1 . Then, the gripping members 58 move radially outward to grip the tire 1 .

[0131] Then, if Figure 12 As shown in (a), the movable frame 52 of the second supply device 22 moves toward the pasting device 23. At this time, the moving mechanism 32 and the retaining member 31 of the pasting device 23 are inserted into the opening 57a formed in the holding frame 57 of the holding mechanism 53 (see Figure 10 ), the annular component 10 held by the retainer 31 is inserted into the interior of the tire 1.

[0132] Then, if Figure 12 As shown in FIG. 1 ( b ), the holder 31 is moved to a radially outer bonding position by the moving mechanism 32 , and the annular member 10 is bonded to the inner peripheral surface 1 a of the tire 1 .

[0133] When the annular member 10 is attached to the inner peripheral surface 1a of the tire 1, Figure 13 As shown in (a), the retaining member 31 is moved to the first retreat position again by the moving mechanism 32. Figure 13 As shown in (b) , the movable frame 52 moves in a direction away from the pasting device 23 .

[0134] Then, the gripping mechanism 53 releases the gripping of the tire 1 to which the annular member 10 is bonded, and the operator carries the tire 1 from the mounting platform 60 to the next step.

[0135] (Specific order)

[0136] Next, we will explain in more detail Figure 12 (a)~ Figure 13 The order shown in (a).

[0137] Figure 14 and Figure 15 It is an explanatory diagram showing the procedure of attaching the annular member 10 to the tire 1 as seen from the side.

[0138] like Figure 14 As shown in (a), after the pasting device 23 forms the annular component 10, the multiple retainers 31 move to the "first retreat position", thereby shrinking the annular component 10 to be smaller than the inner diameter of the tire 1, so that the annular component 10 can be inserted into the interior of the tire 1.

[0139] like Figure 14 As shown in (b), the attaching device 23 attaches the annular component 10 to the inner circumferential surface 1a of the tire 1 by moving the plurality of retaining members 31 to the radially outer "attachment position." At this time, only the portion of the annular component 10 retained by the retaining members 36 is adhered to the inner circumferential surface 1a of the tire 1, while the remaining portion is either lifted from the inner circumferential surface 1a of the tire 1 or slightly adhered.

[0140] Next, the sticking device 23 releases the holding member 31 from holding the annular member 10, as shown in FIG. Figure 14As shown in (c), the retainer 31 is moved to the second retracted position. The second retracted position is radially outward of the first retracted position when the annular member 10 is inserted into the tire 1, and is radially inwardly spaced from the annular member 10 adhered to the inner circumferential surface 1a of the tire 1. Therefore, compared to the case where the retainer 31 is moved to the first retracted position, the retainer 31 can be moved a shorter distance, thereby shortening the cycle time of the adhesion operation.

[0141] Then, if Figure 15 As shown in (a), the attaching device 23 rotates the retainer 31 in the direction of arrow b via the rotating mechanism 33, positioning the retainer 31 radially inward of the portion of the annular member 10 not attached to the inner circumferential surface 1a of the tire 1. In this embodiment, since eight retainers 31 are provided, the circumferential spacing of the retainers 31 is 22.5° around the axis C1. Therefore, the attaching device 23 rotates each retainer 31 22.5° around the axis C1.

[0142] Then, if Figure 15 As shown in FIG. 2( b ), the sticking device 23 moves the holders 31 radially outward by the moving mechanism 32 , and presses the annular member 10 from the radial inside by each holder 31 to stick it to the inner circumferential surface 1 a of the tire 1 .

[0143] Then, if Figure 15 As shown in (c), the attaching device 23 rotates each retainer 31 about the axis C1 in the direction of arrow b via the rotating mechanism 33. As a result, the first roller 37a and second roller 37b of the retainer 31 travel along the inner circumference of the annular member 10, pressing the annular member 10 against the inner circumference 1a of the tire 1. This completes the attachment of the annular member 10 to the inner circumference 1a of the tire 1.

[0144] [Modification Example of Tire 1]

[0145] Figure 16 It is a cross-sectional view showing a modified example of the tire 1 .

[0146] The tire 1 of this modified example has a sealant 61 applied to its inner circumferential surface 1a. By applying the sealant 61 to the inner circumferential surface 1a of the tire 1, holes created by nails or the like penetrating the tread 2 are blocked, thereby preventing rupture. The sealant 61 is made of a conventionally known material, such as a rubber component, a liquid polymer, and a cross-linking agent, and exhibits adhesive properties.

[0147] The annular member 10 is provided radially inside the sealing material 61. The annular member 10 is directly adhered to the sealing material 61 by the adhesiveness of the sealing material 61. Therefore, the sealing material 61 functions as an adhesive for adhering the annular member 10 to the inner circumferential surface 1a of the tire 1.

[0148] [Modification of the holder 31]

[0149] Figure 17 It is a schematic front view showing a modified example of the holder 31 .

[0150] exist Figure 17 In the modified example shown, the first roller 37a is positioned so as to protrude further from the holding surface 36a1 of the holding member 36 than the second roller 37b. Figure 17 In the example shown in (a), the position of the axis of the first roller 37a is closer to the holding surface 36a1 than the position of the axis of the second roller 37b. Figure 17 In the example shown in (b), the axis of the first roller 37a and the axis of the second roller 37b are aligned, but the second roller 37b is formed to have a smaller diameter than the first roller 37a.

[0151] As described above, by making the first roller 37a protrude more from the holding surface 36a1 than the second roller 37b, the first roller 37a and the second roller 37b can be more easily moved along the arcuately curved annular member 10 and the inner circumferential surface 1a of the tire 1.

[0152] [Effects of implementation methods]

[0153] (1) The attaching device 23 of the embodiment described above includes: a plurality of retainers 31 arranged at intervals in the circumferential direction centered on a predetermined axis C1, and retaining the inner circumferential surface of the annular member 10; a moving mechanism 32 for moving the plurality of retainers 31 in the radial direction centered on the axis C1; a rotating mechanism 33 for moving the plurality of retainers 31 in the circumferential direction; and a control device 24. The control device 24 controls the movement of the retainers 31, the moving mechanism 32, and the rotating mechanism 33 to perform the following operations (a) to (f).

[0154] (a) The inner circumferential surface of the annular member 10 is held by the retaining member 31;

[0155] (b) moving the holder 31 holding the annular member 10 toward the radially outer side toward a predetermined pasting position to adhere a portion of the annular member 10 to the inner circumferential surface 1a of the tire 1;

[0156] (c) releasing the retaining member 31 from retaining the annular member 10;

[0157] (d) moving the retainer 31 to a retracted position radially inward of the pasting position so that the retainer 31 is separated from the annular member 10;

[0158] (e) moving the retaining member 31 in the circumferential direction; and

[0159] (f) The holder 31 is moved to the attachment position, and the other portion of the annular member 10 is attached to the inner peripheral surface 1 a of the tire 1 .

[0160] Therefore, the attaching device 23 attaches a portion of the annular component 10 to the inner circumferential surface 1a of the tire 1 using the plurality of retainers 31, temporarily separates the retainers 31 from the annular component 10, and then shifts the circumferential position of the retainers 31 to attach another portion of the annular component 10 to the inner circumferential surface 1a of the tire 1. Thus, the substantially entire annular component 10 can be evenly attached to the inner circumferential surface 1a of the tire 1 without causing wrinkles on the annular component 10.

[0161] (2) The control device 24 of the above embodiment controls the operation of the rotating mechanism 33 after the operation (f) so that the retainer 31 is moved in the circumferential direction while the annular component 10 is pressed against the inner circumferential surface 1a of the tire 1 by the retainer 31. Therefore, the annular component 10 can be attached without being lifted from the inner circumferential surface 1a of the tire 1 over the entire circumference.

[0162] (3) The retainer 31 includes a retaining member 36 that retains the annular member 10, and a first roller 37a and a second roller 37b that can roll on the inner circumferential surface of the annular member 10. Therefore, when the retainer 31 is moved circumferentially while the annular member 10 is pressed against the inner circumferential surface 1a of the tire 1 by the retainer 31, the first roller 37a and the second roller 37b roll on the inner circumferential surface of the annular member 10, thereby reducing the movement resistance of the retainer 31. Alternatively, the retainer 31 may include only one of the first roller 37a and the second roller 37b.

[0163] (4) The retracted position of the retainer 31 includes a first retracted position in which the annular component 10 retained by the retainer 31 is contracted to a position smaller than the inner diameter of the tire 1, and a second retracted position located radially between the first retracted position and the attachment position and in which the retainer 31 is separated from the annular component 10 attached to the inner circumferential surface 1a of the tire 1. Therefore, the cycle time from the action (b) of attaching a portion of the annular component 10 to the inner circumferential surface 1a of the tire 1 to the action (f) of moving the retainer 31 in the circumferential direction and attaching another portion of the annular component 10 to the inner circumferential surface 1a of the tire 1 can be shortened.

[0164] (5) The moving mechanism 32 includes a pair of link mechanisms 40, each including a cylinder 42 that is arranged on the axis C1 and extends and contracts in the axial direction along the axis C1, and a link member 43 that is connected to the cylinder 42 at one end and to the holder 31 at the other end. The pair of link mechanisms 40 are provided on both sides of the holder 31 in the axial direction. Therefore, the holder 31 can be moved in the radial direction without changing its axial position by the extension and contraction of the cylinder 42. When the holder 31 is moved from the first retracted position to the attachment position, the holder 31 can be smoothly moved toward the inner circumferential surface 1a of the tire 1.

[0165] (6) The pasting system 20 of the embodiment includes: a pasting device 23 that forms the long strip-shaped member 11 into the annular member 10 and adheres the annular member 10 to the inner circumferential surface 1a of the tire 1; a first supply device 21 that supplies the long strip-shaped member 11 to the pasting device 23; and a second supply device 22 that supplies the tire 1 to the pasting device 23. Therefore, the operation from forming the annular member 10 to adhering the annular member 10 to the tire 1 can be performed consistently.

[0166] (7) The pasting device 23 and the second supply device 22 are adjacently arranged in a first direction X along the axial direction of the annular member 10 formed by the pasting device 23, and the pasting device 23 and the first supply device 21 are adjacently arranged in a second direction Y orthogonal to the first direction X. Figure 2 In the process, the operator can perform the molding and pasting operations of the annular component 10 while moving between position A1 near the first supply device 21, position A2 near the pasting device 23, and position A3 near the second supply device 22, and the operator can move smoothly between the first supply device 21 and the pasting device 23, and between the pasting device 23 and the second supply device 22.

[0167] (8) The pasting method of the above embodiment includes the following steps (a) to (f).

[0168] (a) The inner peripheral surface of the annular member 10 is maintained by a plurality of retainers 31 arranged at intervals in the circumferential direction around a predetermined axis C1;

[0169] (b) moving the retainer 31 holding the annular member 10 toward a predetermined pasting position along the radial direction centered on the axis C1 to adhere a portion of the annular member 10 to the inner circumferential surface of the tire 1;

[0170] (c) releasing the retaining member 31 from retaining the annular member 10;

[0171] (d) moving the retainer 31 to a retracted position radially inward of the pasting position so that the retainer 31 is separated from the annular member 10;

[0172] (e) moving the retaining member 31 in the circumferential direction; and

[0173] (f) The holder 31 is moved to the attachment position, and the other portion of the annular member 10 is attached to the inner peripheral surface 1 a of the tire 1 .

[0174] Therefore, a portion of the annular component 10 can be adhered to the inner circumferential surface 1a of the tire 1 using multiple retaining members 31. After temporarily separating the retaining members 31 from the annular component 10, the circumferential position of the retaining members 31 is offset and another portion of the annular component 10 is adhered to the inner circumferential surface 1a of the tire 1 again. This allows the substantially entire annular component 10 to be evenly adhered to the inner circumferential surface 1a of the tire 1.

[0175] (9) The affixing method of the above embodiment further includes, after step (f), the step of moving the retainer 31 in the circumferential direction while the annular component 10 is pressed against the inner circumferential surface 1a of the tire 1 by the retainer 31. Therefore, the annular component 10 can be affixed in its entirety without being lifted from the inner circumferential surface 1a of the tire 1.

[0176] (10) The bonding method of the above embodiment further includes, before step (b), the step of applying a sealing material 61 for bonding the annular member 10 to the inner circumferential surface 1a of the tire 1. Thus, the annular member 10 can be bonded to the inner circumferential surface 1a of the tire 1 using the sealing material 61 for preventing the tire 1 from rupturing as an adhesive.

[0177] (11) The tire 1 of the above-described embodiment (modification) includes the sealing material 61 provided on the inner circumferential surface 1a and the annular component 10 provided radially inward of the sealing material 61. Therefore, the annular component 10 can be adhered to the inner circumferential surface 1a of the tire 1 using the sealing material 61 for preventing the tire 1 from rupturing as an adhesive.

[0178] (12) The molding device (attaching device) 23 for the annular member 10 of the above-described embodiment includes: a plurality of holders 31 arranged at intervals in a circumferential direction centered on a predetermined axis C1 to hold the long strip-shaped member 11; a rotating mechanism 33 for moving the plurality of holders 31 in the circumferential direction; and a control device 24 for controlling the movement of the holders 31 and the rotating mechanism 33. The control device 24 controls the movement of the holders 31 and the rotating mechanism 33 to perform the following operations (a) to (c).

[0179] (a) using a retaining member 31 to hold one end portion 11a of the long strip-shaped member 11 in the longitudinal direction;

[0180] (b) moving the holder 31 along the circumferential direction to sequentially position the long strip-shaped member 11 on the other plurality of holders 31;

[0181] (c) The long strip-shaped member 11 positioned on the other holder 31 is held by the holder 31 .

[0182] Therefore, the long belt-shaped member 11 can be automatically formed into an annular shape by the plurality of holders 31 , and the burden on the operator can be reduced.

[0183] (13) In the above embodiment, in the operation (b), the holder 31 is temporarily stopped each time the long strip-shaped member 11 is positioned on the holder 31. Therefore, the ring-shaped member 10 can be held by the holder 31 in a stable state.

[0184] (14) The molding device (attaching device) 23 of the above embodiment further includes a pressing mechanism 34 that presses the long strip-shaped member 11 positioned on the holder 31 against the holder 31. Therefore, the long strip-shaped member 11 does not float from the holder 31, and the holder 31 can reliably hold the long strip-shaped member 11.

[0185] (15) Figure 9 As shown, the long strip-shaped member 11 of the above embodiment has a protrusion 11d formed on one of its longitudinal end and the other end, and a recess 11c formed on the other end to engage with the protrusion 11d. Therefore, the bonding strength between the one end and the other end of the long strip-shaped member 11 can be increased, and the annular member 10 can be reliably formed.

[0186] (16) The molding method of the annular member 10 of the above embodiment includes the following steps:

[0187] (a) holding one end portion 11a of the long strip-shaped member 11 in the longitudinal direction by a holder 31 disposed at an uppermost position among a plurality of holders 31 disposed at intervals in the circumferential direction around a predetermined axis C1;

[0188] (b) moving the plurality of holders 31 in the circumferential direction to sequentially position the long strip-shaped member 11 on the plurality of holders 31; and

[0189] (c) The long strip-shaped member 11 positioned on each holder 31 is held by the holder 31 .

[0190] Therefore, the long belt-shaped member 11 can be automatically formed into an annular shape by the plurality of holders 31 , and the burden on the operator can be reduced.

[0191] (17) In the pasting method of the above embodiment, in step (b), the holder 31 is temporarily stopped each time the long strip-shaped member 11 is positioned on the holder 31. Therefore, the long strip-shaped member 11 can be held by the holder 31 in a stable state.

[0192] As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said specific embodiment, It can be implemented by various changes.

[0193] The present invention is not limited to sponge materials for vibration isolation or sound absorption, but is applicable to all annular members 10 that exhibit predetermined functions by being attached to the inner peripheral surface 1 a of the tire 1 .
