Description

  The present invention relates to a sticking device for sticking a sticking type wheel balance weight to an inner peripheral surface of a rim of a wheel.

  In the wheel assembly state in which tires such as automobiles are incorporated in the rim, if the imbalance in the circumferential direction around the rotation axis of the wheel assembly and the rotation axis direction becomes large, problems such as generation of vibration, noise, etc. may occur during traveling. Become. This vibration and noise are caused by the unbalance of the wheel assembly, and a balance weight is attached to the wheel to counteract this unbalance.

  As the wheel balance weight attached to the wheel, for example, there is a wheel balance weight in which a substantially plate-like weight having a predetermined weight is bonded to the inner peripheral surface of the rim by means such as an adhesive tape.

  The wheel balance weight is formed in a flat plate shape at the time of manufacture, and the weight is curved along the inner peripheral surface of the rim of the wheel when mounted on the wheel. That is, the curvature of the inner peripheral surface of the rim to which the wheel balance weight is attached varies depending on the wheel to be attached.

  Moreover, the conventional wheel balance weight was formed of lead, which is a soft material. The weight formed of lead is easy to process and can be easily molded by human power. However, it is known that lead places a great burden on the environment. For this reason, iron-based alloys that have a low environmental load are being used as weight materials. For this reason, wheel balance weights having iron weights have been used.

  However, if the wheel balance weight with an iron weight is crimped to the inner peripheral surface of the wheel by hand as in the past, iron is harder than lead and difficult to form (deform) manually. Therefore, there was a problem in workability. For this reason, sticking of the wheel balance weight to the wheel is performed using a sticking device. As this sticking apparatus, it is disclosed by patent documents 1-3, for example.

  For example, in Patent Document 1, a steel balance wheel balance weight is placed on a balance weight receiving plate, and the position is maintained by adsorbing it to a rubber plate magnet, the jig is lowered into the wheel, and the wheel balance weight position is set to the wheel. An affixing device is disclosed that is capable of accurately affixing a steel affixing wheel balance weight to a designated position on the inner surface of the wheel by positioning, operating the cylinder, and moving the balance weight receiving plate forward to the wheel side. Yes.

  Patent Document 2 discloses a sticking device that does not require a compressed air source and can stick a wheel balance weight manually.

  Patent Document 3 discloses a sticking device that does not require a compressed air source and can manually attach a wheel balance weight and adjust the radius of curvature of the cushion mounting plate according to the nominal diameter of the wheel. Yes.

However, in the pasting device described in each of the above patent documents, it is necessary to adjust (or replace) the balance weight receiving plate for holding the wheel balance weight for each wheel in order to attach the balance weight to the wheels having different nominal diameters. was there. That is, workability when attaching the wheel balance weight to various wheels having different nominal diameters was low.

  The present invention has been made in view of the above circumstances, and provides a device for attaching a wheel balance weight that is excellent in workability when attaching a wheel balance weight and can attach the wheel balance weight with a strong adhesive force. The task is to do.

  In order to solve the above-mentioned problems, the present inventors have made a study as a result of studying a wheel balance weight sticking device.

In other words, the wheel balance weight attaching device of the present invention reciprocates the pressing member that presses the attaching type wheel balance weight located on the inner peripheral surface of the wheel rim, and the pressing member in the radial direction of the wheel. A wheel balance weight sticking device having a drive means, and driving the drive means to shift the pressure member outward in the radial direction of the wheel and pressing the wheel balance weight against the inner peripheral surface. , the pressing surface has to face the inner peripheral surface of the rim of the wheel, and substantially a belt-shaped pressing plate bendable, is connected to the substantially central portion of the substantially strip-shaped length direction of the one end pressing plate and the other end driving means And a urging means for urging the presser plate against the rim.

  In the wheel balance weight sticking device of the present invention, the pressing plate is pressed against the wheel rim by the connecting member and the biasing member. That is, not only the force generated by driving the driving means but also the force based on the urging member presses the wheel balance weight. And since the force by an urging means acts on the position different from the force by a drive means, the whole wheel balance weight can be pressed. As a result, the wheel balance weight sticking device of the present invention can stick the wheel balance weight to the wheel in a state having high adhesion, and the adhesion between the wheel balance weight and the wheel is improved. The adhesion to the wheel is improved and the wheel balance weight cannot be easily detached from the wheel.

  The wheel balance weight pasting device according to the present invention includes a pressing member that presses an affixing-type wheel balance weight located on an inner peripheral surface of a wheel rim, and a driving unit that reciprocates the pressing member in the radial direction of the wheel. And a wheel balance weight sticking device for driving the driving means to shift the pressing member radially outward of the wheel and pressing the wheel balance weight against the inner peripheral surface.

The applier of the present invention, the pressing member, the pressing surfaces have to face the inner peripheral surface of the rim of the wheel, and substantially a belt-shaped pressing plate bendable, quasi-strip length direction of the end pressing plate And a connecting member connected to the driving means at the other end, and further, biasing means for biasing the pressing plate to the rim.

  Since the pressing member has a pressing plate and a connection member, the wheel balance weight can be pressed against the inner peripheral surface of the rim of the wheel by driving the driving means by driving the driving means.

  And the sticking apparatus of this invention has a biasing means which biases the pressing plate. By having the urging means, the force that presses the entire wheel balance weight does not vary, and the wheel balance weight can be attached more firmly. Specifically, when the wheel balance weight is attached, stress from the driving means is applied to the substantially central portion of the presser plate in the circumferential direction of the wheel. Then, the wheel balance weight is pressed against the rim of the wheel by the stress based on the rigidity of the presser plate itself at the other part of the presser plate. And by having an urging | biasing means, further stress is provided to the other part of this pressing board, and a wheel balance weight is crimped | bonded. Thereby, a wheel balance weight can be stuck firmly.

  The urging means is not particularly limited as long as it can urge the pressing plate to the rim. For example, a cylinder and a spring can be raised. Further, the number of urging means is not particularly limited.

  It is preferable that the pressing member presses the wheel balance weight temporarily fixed to the inner peripheral surface of the wheel. That is, the wheel balance weight can be pasted by temporarily fixing the wheel balance weight in a predetermined position of the wheel in advance and pressing the temporarily fixed wheel balance weight with the pressing member. The temporary fixing of the wheel balance weight indicates a state in which the wheel balance weight is arranged so as not to shift to a predetermined position of the wheel. The temporarily fixed wheel balance weight is preferably a wheel balance weight in a state in which an affixed wheel balance weight is affixed to the wheel by hand.

  The pressing member is preferably formed on the pressing surface so as to be able to support the wheel balance weight, and it is preferable that the pressing member is changed and the wheel balance weight is attached while the wheel balance weight is supported. That is, by forming the pressing member so as to support the wheel balance weight, it is not necessary to temporarily fix the wheel balance weight when the wheel balance weight is attached.

In the affixing device of the present invention, the pressing plate of the pressing member can be curved so that the pressing surface facing the wheel balance weight (or the inner peripheral surface of the wheel rim) follows the curved shape of the inner peripheral surface of the wheel rim. Is formed. Since the pressing surface of the presser plate is formed to be able to bend, the presser plate itself curves to match the inner peripheral surface of the wheel when the wheel balance weight is pressed against the wheel, and the wheel balance weight is crimped to the wheel. can do. This eliminates the need to adjust the pressing member for each wheel size, improving the workability of attaching the wheel balance weight. Furthermore, the sticking device of the present invention can press the entire wheel balance weight by curving the pressing surface of the pressing plate. For this reason, the whole wheel balance weight adheres to a wheel, and is affixed with high adhesive force.

  In the sticking device of the present invention, the biasing means is preferably at least one of a coil spring, a leaf spring, and a cylinder. When the biasing means is a coil spring or a leaf spring, the pressing plate can be biased with a simple structure. Further, when the urging means is a cylinder, the amount of displacement of the cylinder can be controlled, whereby the stress for urging the pressing plate can be adjusted.

  It is preferable that the urging means includes at least one coil spring, and the coil spring is held so that one end thereof is in contact with the pressing plate and the other end is not changed. Since the other end portion of the coil spring is held so as not to change, the pressing plate can be pressed by the one end portion. The other end of the coil spring may be held as long as the other end is not displaced when the coil spring urges the holding plate, and the counterpart member to be held is not limited. For example, a member for holding may be provided, or it may be held by a device such as a driving means arranged to face the pressing plate. In addition, the method of holding the coil spring is not particularly limited, and a method of forming a groove or a hole into which the other end is inserted into the mating member in the mating member and inserting and holding the hole or groove, It can hold | maintain by methods, such as the method of latching a coil spring to an other party member. Moreover, the coil spring should just be hold | maintained so that it may not remove | deviate at least when the urging | biasing force is provided to the holding | suppressing board, and the other end part may be fixed even if it is not fixed. At least when the biasing force is not applied to the pressing plate, the coil spring may be held so as not to come off.

  Here, when the biasing means is formed of a coil spring with the other end fixed, it is preferable that one end is not fixed to the pressing plate. When one end of the coil spring is fixed to the holding plate, stress in a strange direction due to the deformation of the coil spring is applied to the holding plate as the holding plate is bent, and the degree of freedom of the coil spring is reduced, so Is likely to occur.

  Preferably, the urging means is composed of at least one coil spring, and a substantially rod-shaped guide member is disposed on the axial center portion of the coil spring. By having the guide member, the coil spring can be prevented from coming off, and the direction in which the coil spring urges the holding plate can be held constant.

  Preferably, the urging means is composed of at least two coil springs, and the spring constant of the coil spring close to the connection member of the two coil springs is smaller than the spring constant of the coil spring separated from the connection member. By becoming such a form, a big urging | biasing force can be provided to the edge part side of a pressing board, and a wheel balance weight can be affixed more firmly.

  In the attaching device of the present invention, the material of the presser plate is not particularly limited as long as the presser plate is formed so as to be able to bend along the curved shape of the inner peripheral surface when pressed against the inner peripheral surface of the rim. Absent. For example, an integral member having a predetermined rigidity and elasticity and a member formed by laminating thin plates so as to have a predetermined rigidity and elasticity can be cited.

  In the attaching device of the present invention, it is preferable that the pressing plate has at least one metal plate. This metal plate exhibits the rigidity of the pressing plate, and the pressing surface is curved along the inner peripheral surface of the wheel rim. Further, by having the metal plate, the pressing plate exhibits elasticity, and the entire wheel balance weight can be pressed against the inner peripheral surface of the rim. In this embodiment, at least one metal plate may be used, and even if the pressing plate is formed of only one metal plate, it is laminated with at least one thin plate made of rubber or resin. It may be formed in a state.

  When the pressing plate has at least one metal plate, the material of the metal plate is not particularly limited, and is preferably made of an iron-based metal such as stainless steel, steel, or spring steel.

  When the pressing plate has at least one metal plate, the pressing surface of the pressing plate is preferably formed of a metal plate. The pressing surface of the pressing plate is a surface pressed against the wheel in order to attach the wheel balance weight, and wear of the pressing plate can be suppressed by forming this surface with metal. As a result, even if the wheel balance weight is repeatedly applied, it is not necessary to replace the holding plate due to wear of the holding plate, and as a result, the cost required for applying can be reduced.

  It is preferable that the pressing plate has at least two metal plates in a stacked state, and the lengths of the metal plates are different. By having the metal plate in which the pressing plate is laminated, each metal plate exhibits elasticity. And since the length of each metal plate differs, the force (force which presses a press surface against the internal peripheral surface of a rim) which the whole press plate produces can be adjusted. This form is a form that should have at least two metal plates, and even if the pressing plate is formed only from two metal plates laminated, at least one thin plate made of rubber, resin, etc. It may be formed in a laminated state.

  It is preferable that the length of the metal plate located on the outer side in the circumferential direction of the wheel is longer than that of the metal plate located on the inner side in the outer circumferential direction. Such a configuration is a so-called leaf spring and can adjust the force generated by the entire pressing plate (the force pressing the pressing surface against the inner peripheral surface of the rim).

  It is preferable that both ends of the pressing surface of the pressing member with respect to the circumferential direction of the wheel have a smaller radius of curvature than the curved shape of the inner peripheral surface of the rim of the wheel. Both end portions of the pressing member are portions that first contact the rim when the pressing member is pressed against the inner peripheral surface of the rim, and the pressing member contacts the rim because the portion is formed to be curved. Sometimes the end of the pressing member slides against the rim. Thereby, it can prevent that a press member damages the internal peripheral surface of a wheel.

  The pressing surface of the pressing member preferably has a larger radius of curvature than the curved shape of the inner peripheral surface of the wheel. Since the pressing surface of the pressing member has a larger radius of curvature than the inner peripheral surface of the rim of the wheel, when the pressing member is pressed against the inner peripheral surface of the rim, the pressing surface of the pressing member is curved and the entire wheel balance weight Can be pressed against the rim. More preferably, the pressing surface of the pressing member has a larger radius of curvature than the curved shape of the inner peripheral surface of the largest wheel in which the attaching device of the present invention is used.

  The wheel balance weight that is affixed to the wheel by the affixing device of the present invention is a so-called affixing-type wheel balance weight in which a weight adjusted to a predetermined weight is affixed to the wheel by an adhesive means such as a double-sided tape. As shown in FIG. 9, the affixing type wheel balance weight is composed of a weight 80 made of a substantially band-shaped metal plate and a double-sided tape 81 having one adhesive surface affixed to the back surface of the weight 80. There is a form. As another form, as shown in FIG. 10, there is a form in which a plurality of weight pieces 82 and a plurality of weight pieces 82 are attached to one adhesive surface of the double-sided tape 81 in a state where they are arranged in the longitudinal direction. .

  Further, the material of the weight constituting the wheel balance weight is not limited. For example, lead metal, iron metal, and zinc metal can be used. Of these weights made of metal, the attaching device of the present invention can press the entire weight against the wheel with a strong force, so that the wheel balance using a weight made of a hard metal such as an iron-based metal or a zinc-based metal is used. Effective for sticking weights.

  Hereinafter, the present invention will be described using examples.

  As an example of the present invention, a device for attaching a wheel balance weight was manufactured.

Example 1
As shown in FIG. 1, a sticking device 1 for an iron sticking type wheel balance weight according to this embodiment includes a driving means 2, a pressing member 3, a receiving side member 4, a biasing member 5, and a driving means. 2 has a base material (not shown) for fixing.

  The driving means 2 includes an air cylinder 20 that drives the pressing member 3 so as to be able to reciprocate. The driving means 2 has a receiving cylinder (not shown) in a direction opposite to the direction in which the pressing member 3 reciprocates, and reciprocates the receiving member 4.

  The pressing member 3 includes a connection member 30 and a pressing plate 31.

  The connection member 30 is a substantially rod-shaped member having one end connected and fixed to the cylinder of the air cylinder 20 and the other end to which the holding plate 31 is fixed.

  The pressing plate 31 is made of a substantially band-shaped metal plate having a pressing surface 31a facing the wheel balance weight. The pressing plate 31 is connected and fixed to the connecting member 30 at a substantially central portion of a substantially band-shaped metal plate. The pressing plate 31 is fixed in a state in which the pressing surface 31a extends in the circumferential direction of the wheel. In the present embodiment, the pressing plate 31 made of a metal plate and the connecting member 30 are fixed by welding. Since the pressing plate 31 is made of a metal plate and joined to the connecting member 30 by welding, the pressing surface 31a of the pressing plate 31 is a smooth surface without unevenness.

  The pressing plate 31 is formed in a substantially flat plate shape, and is formed by bending both end portions in a substantially band-like length direction (a circumferential direction of the corresponding wheel).

  The receiving side member 4 is a member that is pressed to a position symmetrical to the axis of the wheel when the driving unit 2 drives the pressing member 3 to press the pressing plate 31 against the inner peripheral surface of the wheel rim. By having the receiving side member 4, the pressing member 3 is pressed against the rim with a desired pressing force. Although the form in particular is not limited, the receiving side member 4 used the conventionally well-known member in the present Example.

  The urging member 5 is a member that urges the end of the pressing plate 31 to the wheel. In the present embodiment, the urging member 5 includes a single spring (coil spring) 50 having one end fixed to the driving means 2 by welding. Two urging members 5 are provided so as to urge each of the end portions of the pressing plate 31 in the length direction.

(Attaching wheel balance weight)
The wheel balance weight shown in FIG. 9 was stuck on the inner peripheral surface of the rim of the wheel using the sticking device 1 of this example. The wheel balance weight 8 includes a weight 80 made of a substantially band-shaped iron plate and a double-sided tape 81 having one adhesive surface attached to the back surface of the weight 80.

  Prior to the application of the wheel balance weight to the wheel, a balance test is performed on the wheel on which the tire is mounted. Based on the test result, the required total weight of the wheel balance weight and the position where the wheel balance weight is applied to the wheel (the position of the center of gravity) ) Is determined. Affixing-type wheel balance weight having a weight corresponding to the determined necessary total weight is prepared, and the center position in the longitudinal direction (the same direction as the wheel circumferential direction) is marked on the wheel balance weight.

  Next, the bonding surface of the pasting type wheel balance weight 8 is exposed, and pasting is performed in a state where the center position of the wheel balance weight coincides with the pasting center position (center of gravity position) marked in advance on the wheel. This pasting was done by manually pressing the weight 80 against the inner peripheral surface of the wheel rim.

  After the wheel balance weight is affixed to the wheel by human power, the affixing device 1 (base material) is inserted into the wheel.

  After the insertion of the base material into the wheel is completed, the air cylinder 20 of the driving means 2 is driven. When the air cylinder 20 is driven, the pressing plate 31 and the receiving side member 4 change. When the shift of the pressing plate 31 and the receiving member 4 proceeds, the receiving member 4 first comes into contact with the inner peripheral surface of the wheel rim, and then both ends of the pressing plate 31 contact the inner peripheral surface of the wheel rim. Touch. And when it changes further, a curved deformation | transformation will be produced in the shape from which the center part of the pressing board 31 becomes convex. Further, both end portions of the pressing plate 31 slide on the inner peripheral surface of the rim of the wheel, and the contact position changes. When the shift of the pressing plate 31 proceeds, the central portion of the pressing plate 31 (the portion where the connecting member 30 is joined) abuts the rim. At this time, the pressing plate 31 comes into contact with the inner peripheral surface of the rim due to the elasticity of the pressing plate 31 itself.

  Further, when the driving means 2 is driven so as to advance the displacement of the pressing plate 31, the pressing plate 31 presses the inner peripheral surface of the rim. Due to this pressing force, the wheel balance weight 8 that is affixed by hand to the inner peripheral surface of the rim is pressed and brought into close contact with the wheel. Thereby, the wheel balance weight was affixed on the inner peripheral surface of the rim. Here, since the whole wheel balance weight is pressed by the pressing plate 31, it has a stronger adhesive force.

  Next, the air cylinder 20 of the drive means 2 is driven in the reverse direction to retract the pressing plate 31. While the wheel balance weight is adhered to the inner peripheral surface of the rim of the wheel, only the pressing plate 31 moves backward.

  As described above, the wheel balance weight could be pasted by the pasting apparatus of this example.

  As described above, when the air cylinder 20 is driven and the wheel balance weight is pressed against the wheel by the pressing plate 31, the central portion is pressed through the connecting member 30, and both ends are pressed by the elasticity of the pressing plate 31 itself. Applying pressure. And by having the urging means 5 as in this embodiment, both end portions are pressed by the urging means 5 and the adhesion of the wheel balance weight is improved.

  In particular, the weight made of an iron plate does not bend to a shape that matches the inner peripheral surface of the wheel rim only by human power due to its own rigidity, but the wheel balance weight with a stronger pressing force in the pasting device of this embodiment. Since the weight 80 is pressed against the wheel, the weight 80 is curved along the curved shape of the wheel, and exhibits a stronger adhesive force.

  Moreover, since the pressing plate 31 curves along the inner peripheral surface of the rim to which the wheel balance weight is attached, it is not necessary to replace the pressing member 3 for each wheel. That is, the wheel balance weight can be attached to various wheels without replacing the pressing member 3 with a single device, and the workability of attaching the wheel balance weight is improved.

(Example 2)
The present embodiment is a sticking device having the same configuration as that of the first embodiment except that the urging means 5 includes two springs 51 and 52. Here, the two springs 51 and 52 are arranged such that the spring constants of the springs 52 located on the end side of the holding plate 31 are larger than the spring constants of the springs 51 located on the inside. Yes. The configuration of the sticking device of this example is shown in FIG.

  The present embodiment exhibits the same effect as the first embodiment except that the number of springs is different. Since the spring constants of the two springs 51 and 52 are different, the end side of the pressing plate can be pressed against the rim with a stronger urging force. As a result, the wheel balance weight can be more firmly attached. it can.

The configuration in the vicinity of the fixing portion of the spring 50 of the sticking device of this example is shown in a sectional view in FIG. FIG. 5 is a diagram showing one place where the spring 50 is fixed by the metal fitting 53. In this embodiment, such a fixing method is performed at a plurality of locations.

  In this embodiment, as shown in FIG. 5, one end of the spring 50 is fixed to the driving means 2 with a metal fitting 53. More specifically, this is an example in which a wire that forms a coil spring constituting the spring 50 and is positioned on one end side of the spring 50 is fixed to the driving means 2 by a metal fitting 53.

  This embodiment exhibits the same effect as that of the first embodiment except that the urging means 5 is different.

The locking hole 21 is formed in such a size that its inner diameter substantially coincides with the outer diameter of the coil spring constituting the spring 50. The spring 50 may be lightly pressed into the locking hole 21.

  This embodiment exhibits the same effect as that of the first embodiment except that the urging means 5 is different.

(Example 7)
The present embodiment is a sticking device having the same configuration as that of the first embodiment except that the method for fixing the spring 50 to the driving means 2 is different.

The locking groove 22 is formed so as to form an annular groove into which one end of a coil spring constituting the spring 50 can be inserted. The spring 50 may be lightly press-fitted into the locking groove 22.

  This embodiment exhibits the same effect as that of the first embodiment except that the urging means 5 is different.

(Example 8)
The present embodiment is a sticking device having the same configuration as that of the first embodiment except that the guide rod 25 is formed in the axial center portion of the spring 50. The structure of the sticking apparatus of a present Example was shown in FIG.

  In the present embodiment, as shown in FIG. 8, a guide bar 25 is formed that protrudes from the surface of the driving means 2 that faces the pressing plate 31. The guide rod 25 is inserted into the axial center portion of the spring 50 from one end. The guide rod 25 has an outer diameter smaller than the inner diameter of the spring 50. The length of the guide bar 25 is such that the spring 50 does not come into contact with the presser plate 31 in a state where the urging force is applied to the presser plate 31, and the distance between the tip of the guide bar 25 and the presser plate 31 is as follows. The spring plate 50 is set to be narrower than the free length in a state where no urging force is applied to the pressing plate 31.

  In this embodiment, by having the guide bar 25 penetrating the inside of the spring 50, the direction of the urging force by which the spring 50 urges the holding plate 31 is limited to the direction in which the guide bar 25 extends. Thereby, the direction of the urging force for urging the pressing plate 31 becomes constant, and the pressing plate 31 can press the entire wheel balance weight.

  Further, the spring 50 is prevented from falling off by having the guide rod 25. Due to this restriction, even if the joint between the spring 50 and the drive means 2 is removed, the spring 50 is caught by the guide rod 25 and remains, and the spring 50 does not fall off. Further, even if the joint between the spring 50 and the driving means 2 is removed, the spring 50 can apply a biasing force to the holding plate 31.

  This embodiment exhibits the same effect as that of the first embodiment except that the urging means 5 is different.

Example 9
The present embodiment is a sticking device having the same configuration as that of the first embodiment except that the pressing means 3 is formed so as to be able to support an iron balance weight.

  In the pressing member 3, a magnet is assembled on the back surface of the pressing plate 31, and an iron balance weight is supported on the pressing surface 31a by this magnetic force.

(Attaching wheel balance weight)
Using the sticking device 1 of this example, the wheel balance weight shown in FIG. 9 was stuck on the inner peripheral surface of the rim of the wheel in the same manner as in Example 1.

  As in the case of the first embodiment, the required total weight of the wheel balance weight and the position where the wheel balance weight is applied to the wheel (the position of the center of gravity) are determined.

  Next, the sticking type wheel balance weight 8 is supported by the pressing plate 31. At this time, the wheel balance weight is supported in a state where the adhesion surface faces the outer peripheral direction. Further, the wheel balance weight is supported so that the position of the center of gravity is located on the extension line of the connection member 30. Then, the release paper is removed to expose the adhesive surface, and the substrate is inserted into the wheel.

  Positioning of the wheel balance weight with respect to the wheel is determined by visually observing the center position of the wheel balance weight that is pre-marked on the wheel and the center position of the wheel balance weight that is pre-marked on the wheel balance weight.

  After the positioning of the pasting type wheel balance weight with respect to the wheel is completed, the air cylinder 20 of the driving means 2 is driven. When the air cylinder 20 is driven, the pressing plate 31 and the receiving side member 4 change. When the shift of the pressing plate 31 and the receiving member 4 proceeds, the receiving member 4 first comes into contact with the inner peripheral surface of the wheel rim, and then both ends of the pressing plate 31 contact the inner peripheral surface of the wheel rim. Touch. And when it changes further, a curved deformation | transformation will be produced in the shape from which the center part of the pressing board 31 becomes convex. Further, both end portions of the pressing plate 31 slide on the inner peripheral surface of the rim of the wheel, and the contact position changes. When the shift of the pressing plate 31 proceeds, the central portion of the pressing plate 31 (the portion where the connecting member 30 is joined) abuts the rim. At this time, the pressing plate 31 comes into contact with the inner peripheral surface of the rim due to the elasticity of the pressing plate 31 itself.

  Further, when the driving means 2 is driven so that the pressing plate 31 is moved further, the pressing plate 31 presses the inner peripheral surface of the rim. By this pressing force, the wheel balance weight supported by the pressing surface 31a of the pressing plate 31 is pressed against the inner peripheral surface of the rim. Thereby, the wheel balance weight was affixed on the inner peripheral surface of the rim. Here, since the whole wheel balance weight is pressed by the pressing plate 31, it has a stronger adhesive force.

  Next, the air cylinder 20 of the drive means 2 is driven in the reverse direction to retract the pressing plate 31. While the wheel balance weight is adhered to the inner peripheral surface of the rim of the wheel, only the pressing plate 31 moves backward.

  As described above, the wheel balance weight could be pasted by the pasting apparatus of this example.

  As described above, in the sticking device of this embodiment, the pressing plate 31 can press the entire wheel balance weight against the wheel. As a result, the wheel balance weight is curved along the curved shape of the inner peripheral surface of the wheel, and is bonded with a strong adhesive force.

  Moreover, since the sticking apparatus of a present Example does not require temporary fixation of a wheel balance weight at the time of sticking of a wheel balance weight, it can suppress the raise of the cost required for sticking.

  Moreover, since the pressing plate 31 bends along the inner peripheral surface of the rim to which the wheel balance weight is attached, the attaching device of the present embodiment does not need to replace the pressing member 3 for each wheel. That is, the wheel balance weight can be attached to various wheels without replacing the pressing member 3 with a single device, and the workability of attaching the wheel balance weight is improved.
