Description

The present invention relates to a tire inspection device, and particularly to measures against dust, for example, rubber scraps, which may be present in the tire when air is supplied to the tire for inspection.

Conventionally, as a tire inspection device, for example, there is one disclosed in Patent Document 1. According to the technique of Patent Document 1, after the tire is sandwiched between the upper rim and the lower rim, air is supplied into the tire to expand the tire, and then the inspection is performed. The air supply to the tire penetrated the upper rim and the lower rim, and penetrated in the radial direction of the communication pipe to the portion located between the upper rim and the lower rim of the communication pipe to which the air was supplied inside. This was done by providing a plurality of injection ports at predetermined angles and injecting air into the tire from these injection ports. The communication pipe is formed in the shaft inserted into the upper rim, and the shaft is fitted to the upper rim.

Japanese Unexamined Patent Publication No. 2013-83549

By the way, below the lower rim, a chuck mechanism is provided that locks the vertical movement of the upper rim and fixes the vertical distance from the lower rim. The change in the fixed state between the upper rim and the lower rim by the chuck mechanism affects the measurement accuracy by the load cell provided in the tire inspection device.

Therefore, for example, a material having high hardness is used for the shaft so that wear does not occur at the contact portion between the shaft and the chuck mechanism, and surface treatment is performed so that wear does not occur on the shaft. Further, a lubricant is applied to the shaft contact portion so as not to cause wear or seizure.

However, when air is supplied to the tire, the rubber scraps in the tire are rolled up, and if the rubber scraps enter the contact portion with the shaft of the chuck mechanism, for example, the contact portion is worn or the rubber scraps reach the contact portion. The upper rim may be fixed while the rubber is bitten. As a result, the fixed state of the upper rim changes, which may affect the measurement accuracy. As a cause of rubber scraps entering the chuck mechanism, for example, it is conceivable that rubber scraps penetrate into the chuck mechanism through a gap between the lower rim and the shaft.
The above-mentioned Patent Document 1 is an example in which a shaft fitted to the upper rim is inserted into a chuck mechanism below the lower rim, but an example in which a shaft mounted on the lower rim is inserted into a chuck mechanism above the upper rim. There is also, and the same is true in that case.

An object of the present invention is to provide a tire inspection device that prevents rubber scraps from entering the chuck mechanism when supplying air to a tire.

The tire inspection device according to one aspect of the present invention inspects the tire by rotating the tire together with the upper rim and the lower rim while supplying air into the tire sandwiched between the upper rim and the lower rim. is there. When supplying air into the tire, the air swivel supply unit swirls the air in the tire sandwiched between the upper rim and the lower rim. This swirling flow of air gradually forms an air vortex.

In the tire inspection device configured in this way, when air is supplied into the tire, an air vortex is generated in the tire, so that the air vortex becomes a wall and the rubber scraps accumulated in the tire are generated. It is considered that the air is prevented from being rolled up above the vortex and the stagnant state is maintained. On the other hand, even if the rubber scrap is caught in the air vortex, the rubber scrap only rotates along with the swirling flow of air. As a result, it is possible to appropriately prevent the rubber scraps in the tire from entering the chuck mechanism due to the inflator.

In the tire inspection device of the above aspect, the air swivel supply unit has an injection unit that injects air substantially along the tangential direction of a virtual curve virtually drawn in the tire.

In the tire inspection device configured in this way, an air vortex is generated in the tire by injecting air in the tangential direction of the virtual curve in the tire.

Further, the plurality of injection portions can be arranged at intervals along the virtual curve. With this configuration, an air vortex can be generated more reliably.

The injection portion may be provided on the upper rim, may be provided on the lower rim, or may be provided between the upper rim and the lower rim.

Specifically, for example, the air swirl supply unit is formed so as to penetrate at least one of the upper rim and the lower rim and has an air passage, and the virtual curve is substantially virtual around the air passage. It can be the configuration depicted in.

Alternatively, in the air swirl supply unit, a shaft that also serves as an air passage is inserted between the upper rim and the lower rim, and the shaft penetrates between the upper rim and the lower rim. The formed branch air passage is provided, and the virtual curve may be configured to be substantially drawn around the branch air passage.

The tire inspection device 1 of the first embodiment of the present invention is shown in FIGS. 1 to 3. In this tire inspection device 1, air is supplied into the tire 6 in a state where the upper rim 2 and the lower rim 4 shown in FIG. 1 sandwich the tire 6, and the tire 6 is expanded. In this expanded state, the tire 6 is rotated at a predetermined speed to inspect the dynamic balance of the tire 6.

The lower rim 4 is attached to the support rotating device 5, the upper rim 2 is attached to the elevating device shown by the broken line, and the upper rim 2 is lowered by the elevating device with the tire 6 attached to the lower rim 4. Hold the tire 6.

A through hole 8 is formed in the center of the upper rim 2, an upper rim shaft 10 is inserted through the through hole 8, and a flange 12 at the head thereof is a flat concave surface (recess) on the upper part of the upper rim 2. It is in contact with (bottom surface) 14 and is connected to the concave surface 14 by a bolt (not shown). Inside the upper rim shaft 10, an air supply passage 16 is formed along the length direction thereof.

The upper rim shaft 10 passes through a through hole 18 formed in the center of the lower rim 4 and enters the support rotating device 5 attached to the lower part of the lower rim 4. When the upper rim 2 is lowered by the elevating device, the upper rim shaft 10 is coupled to the air supply source (not shown) inside the support rotating device 5, and the upper rim 2, the lower rim 4, and the tire 6 are integrated. The rotation given to the lower rim 4 by the support rotating device 5 is transmitted to the tire 6, the upper rim shaft 10, and the upper rim 2, and the upper rim 2, the lower rim 4, and the tire 6 rotate integrally. It is configured as follows. The tire inspection device 1 is provided with a chuck mechanism for fixing the vertical positional relationship between the upper rim 2 and the lower rim 4.

That is, as a part of the chuck mechanism, a plurality of grooves 500 are formed on the lower outer peripheral surface of the upper rim shaft 10 at intervals along the length direction thereof, and these grooves 500 are formed as other parts of the chuck mechanism. Four claw blocks 502 are located at predetermined positions around the surface at 90 degree intervals.

Each claw block 502 is attached to the housing 504 of the support rotating device 5, and the housing 504 is attached to the lower rim 4. At the end of the claw block 502 on the upper rim shaft 10 side, a claw 506 that can enter the groove 500 is formed. Each claw block 502 is attached to the housing 504 so as to be able to advance and retreat to the upper rim shaft 10. The end of each claw block 502 opposite to the upper rim shaft 10 projects outward from the housing 504.

Guide pins 508 are attached to the protruding portions, and these guide pins 508 are inserted into guide grooves 512 of the guide block 510 arranged outside the housing 504. The guide groove 512 extends linearly from the upper part to the lower part, obliquely and downwardly inclined outward from the middle part, and then extends straightly to the lower part. The guide block 510 is moved up and down by the drive mechanism of the guide block 510 (not shown), so that the guide pin 508 is guided to the guide groove 512, so that the claw block 502 moves forward and backward, and the claw 506 enters the groove 500. Retreat.

FIG. 1 shows a state in which the claw 506 of the claw block 502 shown on the right side has entered the groove 500, and a state in which the claw 506 of the claw block 502 shown on the left side has retracted from the groove 500. With each claw 506 entering one groove 500, the vertical positional relationship between the upper rim 2 and the lower rim 4 is fixed. With the claw 506 retracted from the groove 500, the vertical positional relationship between the upper rim 2 and the lower rim 4 is released from being fixed.

Since the change in the fixed state between the upper rim 2 and the lower rim 4 affects the measurement accuracy, the upper rim shaft 10 has a hardness so that wear does not occur at the contact portion between the upper rim shaft 10 and the housing 504. The upper rim shaft 10 is surface-treated so as not to cause wear. Further, a lubricant is applied to the contact portion between the upper rim shaft 10 and the housing 504 so as not to cause wear or seizure.

There is a minute gap between the lower rim 4 and the upper rim shaft 10 and between the housing 504 and the upper rim shaft 10. If rubber scraps enter this gap, the fixed state of the upper rim 2 changes as described above, which may affect the measurement accuracy.

A flange 22 formed at the lower end of the support shaft 20 is connected to the flange 12 of the upper rim shaft 10 by a bolt (not shown), and the support shaft 20 and the upper rim shaft 10 are arranged concentrically. The support shaft 20 is coupled to the elevating device, and the support shaft 20 is moved up and down, so that the upper rim 2 is moved up and down together with the upper rim shaft 10.

An annular body 24 is arranged around the flange 12 of the upper rim shaft 10 and is fixed to the concave surface 14 of the upper rim 2 by bolts (not shown). The annular body 24 has an annular inner hole 26 in the center. The annular inner hole 26 contacts the outer peripheral surface of the flange 12 of the upper rim shaft 12 to position the annular body 24. The annular body 24 has a substantially flange-like shape, and the concave portion forms the first air passage 28 with the concave surface 14.

An air communication passage 30 is formed in the flange 12 so that the first air passage 28 communicates with the air supply passage 16 of the upper rim shaft 10. The air communication passage 30 is formed along the radial direction of the flange 12. A plurality of air communication passages 30, for example, six as shown in FIG. 2 are provided. The plurality of air communication passages 30 are arranged around the center of the flange 12, for example, at predetermined angles, for example, at intervals of 60 degrees.

An annular groove 32 is formed on the lower surface of the upper rim 2. The groove 32 has a width from a position corresponding to the outer peripheral surface of the annular body 24 to a position somewhat inclined to the upper rim shaft 10 side, and the lower rim 4 side is open. A virtual curve (here, a virtual circle) is drawn by the grooves 32, and a plurality of, specifically, six injection portions 34 are provided in each groove 32 at predetermined angles, for example, every 60 degrees. There is. This virtual circle is located outside the outer peripheral surface of the upper rim shaft 10.

Here, the virtual curve is a curve virtually drawn in the tire 6, and in the present embodiment, the upper rim 2 has a center (for example, the central axis of the upper rim shaft 10) as this kind of curve. A virtual circle drawn on the side, the lower rim 4 side, and between the upper rim 2 and the lower rim 4 is used. As a curve of this kind, not only a circular curve but also a closed curve such as an ellipse or a cross-sectional shape of an almond can be considered. ) May be drawn. Further, a closed curve having no center may be drawn as long as the action and effect of the present invention can be exhibited.

Therefore, although it is common to the second to fourth embodiments described later, the injection units 34 are not evenly arranged at equal intervals on the virtual circle 38, but within the range in which the effects of the present invention can be exhibited. One or more injection portions 34 can be arranged on the above-mentioned open curve or closed curve such as a virtual arc or an ellipse.

Each of these injection portions 34 communicates with the first air passage 28, and the air supplied from the first air passage 28 is ejected into the tire 6 to expand the tire 6. Here, the air pressure and the amount of air of the injection unit 34 are set in advance so as to generate a swirling flow in the tire 6 and gradually form an air vortex. This air vortex is considered to be at least a tornado-shaped vortex in which the air flow winds up from the virtual circle.

As shown enlarged in FIG. 3A, in each injection portion 34, the communication hole (second air passage) 36 is parallel to the upper rim shaft 10 so as to communicate the first air passage 28 and the groove 32. Is formed. The "air passage" referred to in the present invention is formed by the first air passage 28 and the communication hole 36.

Each communication hole 36 is located on a virtual circle 38 drawn with the central axis of the upper rim shaft 10 as the center when viewed in a plan view. A pipe 40, which is a component of the injection unit 34, is inserted into each of the communication holes 36. A close contact state is maintained between the communication hole 36 and the pipe 40 by sealing or the like so that air does not flow between the communication hole 36 and the pipe 40. One end of these pipes 40 is located on the communication hole 36 side, and the other end is located in the annular groove 32. The end of the pipe 40 on the communication hole 36 side is open and the end on the groove 32 side is closed, but the ejection hole 42 is formed on the peripheral wall on the groove 32 side. As shown by the arrows in FIG. 2, these ejection holes 42 are oriented along the tangential direction and in the same direction at different positions of the virtual circle 38. Each pipe 40 is attached to the fan-shaped flange 46 shown in FIG. 3B by various possible methods such as welding, and the flange 46 is attached to the flange 46 by a bolt 49 inserted into an elongated hole 48 formed in the flange 46. It is fixed to the bottom 33 of the groove 32. Air is ejected from these ejection holes 42 at the same speed and the same flow rate. The air communication passage 30, the first air passage 28, the communication hole 36, and the injection unit 34 form an air swirl supply unit.

In the tire inspection device 1, when the tire is sandwiched between the upper rim 2 and the lower rim 4 and air is supplied from the air supply source in the support rotating device 5 to the air supply passage 16, the air is supplied to each air communication passage 30. It is ejected from the ejection hole 42 of the injection portion 34 through the first air passage 28 and the communication hole 36 to expand the tire 6. At this time, since the ejection holes 42 are oriented in the same direction along the tangential direction of the virtual circle 38 shown in FIG. 2, a swirling flow that goes around the upper rim shaft 10 is formed in the tire 6. This swirling flow gradually becomes an air vortex.

It is considered that the air vortex acts as a wall to prevent the rubber scraps accumulated in the tire from being rolled up above the air vortex and maintain the accumulated state. On the other hand, even if the rubber scrap is caught in the air vortex, the rubber scrap only rotates along with the swirling flow of air. As a result, it is possible to appropriately prevent the rubber scraps in the tire from entering the chuck mechanism due to the inflator.

The tire inspection device 1a of the second embodiment of the present invention is shown in FIG. In the first embodiment, the injection portion 34 is provided on the upper rim 4, and the annular body 24 is provided around the flange 12 of the upper rim shaft 10. However, in the tire inspection device 1a of the second embodiment, these are removed. Has been done. A groove 32a similar to the annular groove 32 formed in the upper rim 2 of the tire inspection device 1 of the first embodiment is formed on the upper surface side of the lower rim 4. In the tire inspection device 1a of the second embodiment, the annular groove 32a is open to the upper rim 2 side. An injection unit 34a having the same configuration as the injection unit 34 of the first embodiment is provided in the groove 32a in a state where the injection unit 34 is upside down.

In the tire inspection device 1a of the second embodiment, as in the tire inspection device 1 of the first embodiment, each injection unit 34a is located on the virtual circle, and the respective ejection holes are in the tangential direction of the virtual circle. It is provided in the same direction along the line.

However, in the tire inspection device 1a of the second embodiment, the virtual circle is drawn on the lower rim 4 side, and each injection portion 34a is provided on the virtual circle. Further, in the second embodiment, as an air passage that does not affect the vertical movement of the upper rim 2, for example, the pipe 50 penetrates the lower rim 4 at a position outside the outer peripheral surface of the upper rim shaft 10. However, it is provided linearly toward the injection portion 32a. The pipe 50 goes out of the housing 504 and is connected to an air supply source (not shown).

In this second embodiment, not the upper part of the upper rim shaft 10, but the lower part, for example, generally along the tangential directions at different positions of the virtual circles virtually formed around the pipe 50 for air supply. , Air is injected from each injection unit 34a. Needless to say, also in this second embodiment, each injection unit 34a may be arranged on a virtual arc.

Since other configurations are the same as those of the tire inspection device of the first embodiment, detailed description thereof will be omitted.

Even in the tire inspection device 1a configured in this way, when the tire is sandwiched between the upper rim 2 and the lower rim 4 and air is supplied from the air supply source in the support rotating device to the air supply passage 16, the air becomes a pipe. It is supplied to the injection unit 34a via 50 and ejected to expand the tire 6. At this time, since the ejection holes face the same direction along the tangential direction of the virtual circle, a swirling flow of air is formed in the tire 6. This swirling flow gradually becomes an air vortex.

It is considered that the air vortex acts as a wall to prevent the rubber scraps existing in the tire from rolling up above the air vortex, and the rubber scraps staying in the tire maintain the staying state. .. On the other hand, even if the rubber scrap is caught in the air vortex, the rubber scrap only rotates along with the swirling flow of air. As a result, it is possible to appropriately prevent the rubber scraps in the tire from entering the chuck mechanism due to the inflator.

Further, in the second embodiment, the pipe 50 as the air supply path penetrates the lower rim 4 from the air supply source (not shown) at a position outside the outer peripheral surface of the upper rim shaft 10 and is injected. Since it is provided linearly toward 32a, a pipe that penetrates the upper rim shaft 12 and crosses the inside of the tire 6 and serves as an air flow path that communicates with the air supply passage 18 of the upper rim shaft 10 is provided. However, when adjusting the chuck mechanism to adjust the vertical position of the upper rim 2, the pipe 50 does not get caught in the lower rim 4, and the adjustment of the vertical position of the upper rim 2 is not hindered.

The tire inspection device 1b of the third embodiment is shown in FIG. In the first and second embodiments, the injection portions 34 and 34a are provided on the upper rim 2 or the lower rim 4, but in the tire inspection device 1b of the third embodiment, the upper rim 2 and the lower rim on the upper rim shaft 10 are provided. An injection portion 34b is provided in a portion located between the four and the fourth. In this embodiment, a virtual circle is drawn between the upper rim 2 and the lower rim 4, and the injection unit 34b is located on the virtual circle. In the third embodiment as well, as in the first embodiment, a virtual open curve or a closed curve may be drawn, and one or a plurality of injection portions 34b may be provided on the open curve or the closed curve. Good.

In the third embodiment, a plurality of injection portions 34b are located at different positions on the virtual circle drawn around the central axis of the upper rim shaft 10, and the respective ejection holes 42a are tangent to each of the virtual circles at different positions. It is provided in the same direction along the direction. In each of these injection portions 34b, the tip end portion of the pipe 54 that penetrates the air supply passage 16 in the upper rim shaft 10 and protrudes toward the tire 6 side is bent toward the lower rim 4 side, and the ejection hole 42a is first implemented. It is formed in the same manner as the ejection hole 42 of the form. Since other configurations are the same as those of the tire inspection device 1 of the first embodiment, detailed description thereof will be omitted.

Even in the tire inspection device 1b configured in this way, when the tire is sandwiched between the upper rim 2 and the lower rim 4 and air is supplied from the air supply source in the support rotating device to the air supply passage 16, the air becomes a pipe. It is supplied to each injection unit 34b via 54 and ejected to expand the tire 6. At this time, since the ejection holes 42a face the same direction along the tangential directions at different positions of the virtual circle, a swirling flow of air is formed in the tire 6. The swirling flow is thought to gradually become a tornado-shaped air vortex.

It is considered that the air vortex acts as a wall to prevent the rubber scraps accumulated in the tire from being rolled up above the air vortex and maintain the accumulated state. On the other hand, even if the rubber scrap is caught in the air vortex, the rubber scrap only rotates along with the swirling flow of air. As a result, it is possible to appropriately prevent the rubber scraps in the tire from entering the chuck mechanism due to the inflator.

FIG. 6 shows an injection unit 34c of the tire inspection device of the fourth embodiment. The injection portion 34c has an ejection hole 42b formed on a side wall near the end of a square pipe, and an inclined wall 56 is provided inside the pipe so as to face the ejection hole 42b. Other configurations are similar to any of the first to third embodiments.

By providing the inclined wall 56 in this way, air can be satisfactorily injected in the tangential direction of the virtual circle. Of course, it is also possible to provide an inclined wall inside by using a circular pipe.

In the first to third embodiments, the ejection holes 42, 42a, and 42b are arranged so as to face the tangential direction of the virtual circle, but they can also be arranged so as to deviate from the tangential direction. For example, the ejection holes 42, 42a, and 42b can be arranged so as to be offset from the upper rim shaft 10 side or the tire 6 side with the tangential direction in between. You can also do it.

In the first to third embodiments, the number of the injection portions 34, 34a, 34b is set to 6, but the number is not limited to this, and for example, at least one may be provided. Further, in the first to third embodiments, the injection portions 34, 34a, and 34b are provided along the tangential directions of one virtual circle, but virtual curves (virtual open curves, closed curves, etc.) are concentric. It is also possible to provide a plurality of the above and at least one in the tangential direction of each virtual curve.

In the first embodiment, the air passage is formed in the annular body 24, but this can be removed, and for example, the air communication passage 30 and the pipe 40 of the injection unit 34 can be connected by a pipe. Similarly, in the second embodiment, the air supply source (not shown) and the injection portion 34a are connected by a pipe 50, but as in the first embodiment, the lower rim 4 has the same configuration as the air communication passage 30. The air communication passage and the air passage (the first air passage 28 and the communication hole 36) may be formed, and the air supply passage 16 and the injection portion 34a may be connected by these.

As described above, when the second embodiment has the same air supply path as that of the first embodiment, unlike the case where a pipe is provided as an air flow path that penetrates the shaft and crosses the inside of the tire 6. When adjusting the chuck mechanism to adjust the vertical position of the upper rim, the adjustment of the vertical position is not hindered by the pipe not being caught by the lower rim.

In the first to third embodiments, the virtual circle 38 is drawn around the central axis of the upper rim shaft 10, but if it is within a range that can generate a swirling flow and form an air vortex in the tire. , It may be a virtual circle centered on a position shifted in the horizontal direction from the central axis of the upper rim shaft 10.

The configuration of the air flow path in the present invention is not limited to the examples of the first to third embodiments. Any configuration may be used as long as air can be supplied from the outside of the tire 6 to the injection portions 34a to 34c in the tire 6. For example, in the first to third embodiments, the air flow path is open in the facing region between the upper rim 2 and the lower rim 4, but the present invention is not particularly limited. This depends on the location where the injection portions 34a to 34c are provided, but a special case may be considered in which these injection portions are installed outside the outer peripheral surface of the upper rim 2 or the lower rim 4. In such a case, the air flow path only needs to be finally opened in the direction of the injection portions 34a to 34c, so that it is not particularly necessary to open the air flow path in the facing region.

Further, the structure of the air flow path is not limited to that illustrated in the first to third embodiments, and for example, one or a plurality of air passages having a plurality of branch flow paths from the tip of the main air flow path are tired. The upper rim 2 or the lower rim 4 may be penetrated from the outside of the sixth, and each branch flow path may be opened in the injection portions 34a to 34c. In short, it suffices if the swirling flow can be formed by the injection portions 34a to 34c.

Alternatively, as in the third embodiment (see FIG. 5), the air supply that does not have the function of the upper rim shaft 12 is not formed so as to branch the air passage from the air supply passage 18 of the upper rim shaft 12. A dedicated member may be provided without penetrating the upper rim 2 or the lower rim 4 and may be opened in the injection portions 34a to 34c.

Further, the diameter of the virtual circle 38 is also drawn to be substantially the same as or smaller than the diameter of the upper rim 2 or the lower rim 4 in the first to third embodiments, but it affects the effect of the present invention. It may be larger than the diameter of the upper rim 2 or the lower rim 4 as long as it is within the range.

In the first to third embodiments of the present invention, the air vortex is like a tornado in which the air winds up above the virtual circle, and therefore, in particular, rubber scraps existing below the virtual circle (for example, a tire). The bottom lumps) are blocked by the vortex of air and do not wind up in the tire 6, which is particularly useful as a measure against rubber scraps below the virtual circle.
