Thus, the time required for the tire to be carried out and carried out can be omitted. Effectively check for uniformity. However, such tire inspection devices also have problems that cannot improve the efficiency of tire inspection. Specifically, the distance between the two main shafts is determined according to the maximum outer diameter of the tire, and since the conventional tire inspection device is extremely large in the distance that the drum must move, it takes a long time for the drum to reach from the one spindle to the other spindle. time. This will keep the drum continuously. -5- 201016488 The load is given and the movement is such that the spindle waits for the drum to arrive. Therefore, there is still a result that the tire inspection efficiency cannot be further improved regardless of whether or not the spindle of one drum is provided.

Therefore, when one of the three lift shafts 41 is rotationally driven, the telescopic portion 39 fixed to the nut member 39a of the lift shaft 41 is lifted and lowered. Thereby, the interval between the sensors 29 in the vertical direction is adjusted. The advancing and retracting means 31 is means for elevating and lowering the measuring unit 30 obliquely between the upper position on the upstream side and the lower position on the downstream side with respect to the mounting base 28. The access means 31 according to the present embodiment is constituted by a linear actuator, the lower end of which is fixed to the mounting base 28, and the upper end is fixed to the holding body 38. By the expansion and contraction of the linear actuator (that is, the operation of the inlet and outlet means 31), the measuring unit 30 can measure the shape of the outer shape of the tire T (as shown in Fig. 4(b), the upper side of the upstream side) and the tire. The retracted position at the time of loading or unloading of T (as shown in Fig. 4(a) shows the lower side of the downstream side -16-201016488). The shape measurement position is set to be substantially the same height as the tire inspection position from the tire inspection position to the downstream side separation distance. Further, the retracted position is set such that the measurement unit 30 does not cause the tire T to be carried in or out, and in other words, the upper end of the setting measuring unit 30 does not come into contact with the height of the conveyance of the tire T by the roller conveyor 6. In the present embodiment, the retracted position is a position at which the measuring unit 30 is placed on the mounting table 28, and the upper end of the measuring unit 30 located at the retracted position does not interfere with the unloading means 9 or the tire T carried out therefrom. .

The increase in the movement stroke of the advancing and retracting means 31 can be suppressed. Next, an example of the tire inspection method of the present invention will be described below with reference to Fig. 6. In the initial stage, as shown in a and b of Fig. 6, the first main shaft 3A mounted tire T on the right side is integrally rotated with the main shaft 3A, and the tire T contacts the rotating drum 4. Further, the moving means 33 moves the shape measuring device -17 - 201016488 1 so that the sensor 29 of the measuring unit 30 of the shape measuring device 1 is located on the downstream side of the first main spindle 3Α. At this position, the advancing and retracting means 31 approaches the tire rim at a position where the mounting table 28 moves the holding body 38 to the upper side on the upstream side of the mounting table 28. The three sensors 29 are positioned in the radial direction of the tire casing by the respective expansion and contraction portions 39 held by the holding body 38, and the interval between the sensors 29 in the vertical direction is adjusted by the lifting portion 40. Thereby, the shape measuring device 1 进 completes the movement (movement) of the shape measurement position. In the initial state, as indicated by c in Fig. 6, the first main shaft _3 is driven to rotate in the forward rotation direction by a predetermined number of revolutions (for example, 60 rpm specified by JASOC 60 7) by the rotation drive motor 15, and the driven rotary contact is driven. The drum 4 of the tire T attached to the first main shaft 3A. The load measuring unit 5 for uniformity of the drum 4 measures the force component applied to the drum support 20 from the drum portion 19, and evaluates the forward rotation of the tire T attached to the first main shaft 3A based on the measurement enthalpy. Sentence. * Further, the shape measuring device 1 测量 measures the outer shape of the rotating tire T by the three sensors 29 at the same time as the uniformity measurement. Since the measurement of the shape and the measurement of the uniformity of the tire T can be completed in a short period of time, the shape measuring apparatus 1 〇 starts moving from the shape measurement position toward the retracted position during the progress of the normal rotation uniformity measurement. The retraction of the shape measuring device 10 is such that the sensor corresponding to each of the expansion and contraction portions retreats to the side of the holder 38, and the entry and exit means 31 is retracted to the retracted position by the holder 38, as indicated by d in Fig. 6, When the measurement of the forward rotation uniformity of the first main shaft 3A is completed, the rotation drive motor 15 is rotated in the reverse direction to drive -18- 201016488

In the same manner as the measurement of the forward rotation uniformity, the force component for the uniformity of the reverse rotation of the tire T attached to the first main spindle 3A by the load measuring unit 5 for uniformity is measured. On the other hand, the second main shaft 3B on the left side is fixed with the other tire T carried by the loading means 7, and the tire T is integrally rotated with the second main shaft 3B via the flange 11, thereby completing the uniformity of the tire T. Preparation for the determination. ❿ Once the measurement of the uniformity of the reversal of the tire T attached to the first main shaft 3A is completed, the retraction of the shape measuring device 10 toward the retracted position is also completed. Further, the drum 4 and the shape measuring device 1 start the movement from the first main shaft 3A on the right side toward the second main shaft 3B on the left side. However, compared with the shape measuring apparatus 1 〇, it is difficult to move the drum 4 having the weight from the first main shaft 3A to the second main shaft 3B in a short time, so that the tire T attached to the second main shaft 3 B can be formed to measure the uniformity thereof. There must be a certain amount of time. In addition, the drum 4 must return to the first spindle 3 A again. Therefore, as shown in e and f of Fig. 6, the present embodiment continuously measures the dynamic balance of the first main shaft 3 A on the right side of the drum 4 and replaces the tire T with a new tire. Thereby, the time wasted to wait for the arrival of the drum 4 to be eliminated as much as possible, and efficient inspection efficiency for effectively utilizing the return time of the rotary drum 4 is realized. On the other hand, the comparison of the time between the relatively lightweight shape measuring apparatus 10 and the rotating drum 4 can be moved from the first main shaft 3A to the second main shaft 3B in a short time. Therefore, the reciprocating movement of the shape measuring device 10 between the main shafts 3A and 3B of about 19 to 201016488 can be performed separately from the rotating drum 4 by another driving means, and the shape measuring device can be moved in and out from the retracted position to the shape in the reverse order. The measurement position is prepared, thereby preparing the measurement. In other words, the measurement preparation of the shape measuring device 1 can be performed effectively by the remaining time until the drum 4 reaches the second main shaft 2B, and the uniformity measurement and the outer shape measurement can be performed immediately in accordance with the arrival of the rotating drum 4. As shown in e of Fig. 6, the measurement of the dynamic balance of the tire T attached to the first main shaft 3A is performed as follows. The rotation drive motor 15 rotationally drives the first main shaft 3A at a number of revolutions higher than the uniformity measurement, and the dynamic balance load measuring unit 24 provided between the headstock 1 2 and the support table 17 rotates the tire therein. The chattering (vibration) generated by T is measured as a force component. Based on this measurement, the dynamic balance of the tire T attached to the first main shaft 3A was evaluated. On the other hand, the second main shaft 3B has started to mount the new tire T, and the new tire T is mounted in a short time from the start of the dynamic balance measurement of the tire T attached to the first main shaft 3A. Therefore, as indicated by f in Fig. 6, when the drum 4 reaches the second main shaft 3B, the uniformity measurement and the shape measurement of the tire T attached to the first main shaft 3A are already completed, and there is no need to wait for installation. The measurement of the uniformity of the tire T of the main shaft 3B and the measurement of the outer shape can be started. As described above, in the tire inspection method according to the embodiment, the uniformity of the tire T attached to one of the main spindles is measured while the drum 4 is in contact with the tire T attached to one of the two spindles (for example, the first main shaft 3A).

Therefore, it is not necessary to have a plurality of shapes. Therefore, even if the shape measuring device uses, for example, several types of inspection devices, the device does not cause the entire invention. In the range of the above-described embodiments, the shape and configuration of each member can be appropriately changed. The above-described embodiment is an example of the uniformity measurement of the uniformity measurement balance measuring unit and the shape measuring device 10, and the uniformity of the tire T on the side of the main shaft 3A. During the measurement of the shape of the dome for measurement, the second spindle 3 B < the measurement of the force component for balance measurement and the tire inspection device and the tire inspection method imbalance measuring unit and the shape measuring device of the tire T are performed. For example, the upper 1 may have only the shape measuring device 1 without the dynamic balance measuring unit. At this time, the drum 4 is measured, for example, during the period of the tire T of the shaft 3A, and the uniformity and the outer shape of the tire T are measured, and the drum 4 is opened from the top to the return, and the spindle can be used without reducing the spindle. Check the project of the main shaft separation of one of the parties. It is necessary for the external measuring device of the tire T of the two main shafts 3A, 3B. In addition to changing the nature of the invention, the price of the two parts is not changed, and the dynamic drum 4 is used to measure the first force component and the dynamic setting of the outer tire T. The present invention is limited to the tire-inspecting device having the dynamic description, and the first spindle 3A attached to the first main first spindle 3A is attached to the first main 21 - 201016488. The shape measuring device 1 having the same uniformity of the tire T of the shaft 3A measures the outer shape of the tire rim attached to the other main shaft 3Β. In this case, the shape measuring device 10 can also be used for measuring the outer shape of the tire cymbals attached to the two spindles 3Α and 3Β, and the overall price of the device can be eliminated, and the shape of the outer shape can be effectively measured by one device. Inspection item for the measurement of the uniformity of the two tires. Alternatively, the tire inspection device 1 may include only the uniformity measuring unit and the dynamic balance measuring unit without the shape measuring device 1 . In the above-described embodiment, the measuring unit 30 of the shape measuring device 1 is obliquely moved in and out from the retracted position to the front and the shape measuring position on the upper side by the access means 31, but the tire transporting means 2, 2, 2 from the floor surface When the height is set to be large, as shown in Fig. 7, the holding body 38 can also be raised and lowered in the vertical direction with respect to the upper portion of the mounting table 38. In addition, in the above-described embodiment, the shape measuring device 10 is installed on the floor surface below the tire transporting means 2A and 2B on the downstream side of the main shaft, and the tire inspection position is set above the tire transporting means 2A and 2B, and the shape is measured. The device 10 may be disposed above the tire transporting means 2A, 2B. For example, a support frame fixed to the first frame of the tire inspection device 1 is provided above the tire transporting means 2A, 2', and the outer frame shape of the tire rims provided on the two main shafts 3' and 3'' can be supported by the support frame. A shape measuring device. Further, the present invention can constitute a control device for the tire inspecting device 1, and the tire 4 is moved toward the other main shaft side after the measurement of the uniformity of the tire dam on the one main spindle side, and the tire on the other main spindle side In the period from the completion of the measurement of the homogenization to the one side of the main shaft, the dynamic balance is measured on the side of the main shaft on which the drum 4 is separated. Further, the present invention can constitute a control device for the tire inspecting device 1, and after the drum 4 ends the measurement of the uniformity and the outer shape of the tire T on one side of the main shaft, it moves toward the other main shaft side, and on the other main shaft side. After the measurement of the uniformity and the outer shape of the tire T is completed, the state is returned to the one main spindle side, and the dynamic balance is measured on the side of the main shaft φ in which the drum 4 is separated. Further, the control device for the tire inspection device 1 that further controls the loading means 7 and the unloading means 9 may be configured to replace the tire T on the side of the main shaft on which the drum 4 is separated. In addition, the control device of the tire inspection device 1 may be configured to move the drum 4 and the shape measuring device 10 to the other main shaft side after the measurement of the uniformity and the outer shape of the tire T on one side of the main shaft is performed. The uniformity and shape of the tire T on the other side of the main shaft were measured. In addition, the control device of the tire inspection device 1 may be configured such that the drum 4 is separated from the one main spindle side toward the other main spindle side and returned to one of the main spindle sides, and the drum 4 is separated. The spindle can also be replaced with a tire T. As described above, according to the present invention, it is possible to provide a tire inspection device and a tire inspection method which can effectively perform tire inspection for a plurality of items while rationalizing the device. The tire inspection device according to the present invention includes: a first tire transporting means and a second tire transporting means for transporting the tire to be inspected; and a transport path -23 provided in each of the first tire transport means and the second tire transport means. 201016488 diameter, and freely rotates and supports the first main shaft and the second main shaft of the tire; and reciprocates between the first main shaft and the second main shaft, thereby contacting the drums of each tire mounted on the two main shafts; measuring installation In the tires of the first main shaft and the second main shaft, the uniformity measuring unit for the uniformity of the tire in contact with the drum; and the dynamic balance measuring unit for measuring the dynamic balance of the tire that the drum is not in contact with. In this apparatus, first, the drum is contacted with, for example, the tire attached to the first main shaft, and the uniformity of the tire attached to the first main shaft can be measured. Further, when the drum is separated from the first main shaft, the dynamic balance of the tire attached to the first main shaft can be measured and the tire can be replaced while the drum is returned to the same main shaft. In this way, the time during which the drum moves back and forth between the two main shafts can be effectively utilized, and one tire inspection device can effectively perform inspection for a plurality of items. Moreover, since the measurement of the uniformity and the measurement of the dynamic balance can be performed for each of the two main shafts of one drum, the overall apparatus can be suppressed to be low compared with the apparatus each having a uniform special machine or a dynamic balance special machine. price. In order to obtain a rationalization of the apparatus, the tire inspection apparatus includes: a mounting table that can move the shape measuring device in a direction parallel to a moving direction of the drum; a measuring unit that measures an outer shape of the tire; and The measuring unit is coupled to the mounting table so that the measuring unit can preferably freely enter and exit the mounting position between the shape measuring position at which the outer shape of the tire can be measured and the retracted position for loading or unloading the tire. In the conventional uniformity-specific machine, the shape measuring device for measuring the outer shape is generally provided on each of the main shafts, or is disposed at a different place from the uniform machine of the uniform-24-201016488, Patent Documents 1 and 2 The tire inspection device having two spindles is not provided with an external shape measuring device. Further, in recent years, a two-dimensional inspection type geometric device or the like has been gradually used. This geometry and yaw device are much more expensive, and the construction of devices that require geometry at each spindle can lead to price hikes. In contrast, as described above, when one shape measuring device is reciprocated between two spindles and the shape of the ® tire that is attached to the two spindles by one shape measuring device is measured, it is not necessary to have a plurality of shape measuring devices. Even if a high-priced shape measuring device such as a geometric device is used, there is no possibility that the device price will rise. Further, the shape measuring device is preferably configured to measure the outer shape of the tire by measuring the uniformity of the tire attached to each of the main shafts, thereby achieving an efficient outer shape measurement. Further, the shape measuring device includes: a mounting table movable in a direction parallel to a moving direction of the drum; a measuring unit that measures the shape of the tire shape®; and the measuring unit is coupled to the mounting table It is preferable that the measuring unit can move in and out between the shape measuring position at which the outer shape of the tire can be measured and the retracted position of the loading/unloading position of the tire with respect to the mounting table. The feeding means can retract the measuring unit of the shape measuring device from the shape measuring position to the retracted position, thereby achieving smooth movement of the shape measuring device from one main spindle side to the other main spindle side, and smooth loading and unloading of the tire. . Further, the shape measuring device is preferably provided on the downstream side of the main shaft on the conveyance path of the tire transport means, and the shape measurement - 25 - 201016488 position and the retracted position are provided on the tire transport means The same side of the direction is preferred. The above-described feeding means may cause the measuring unit to move up and down obliquely between the shape measuring position and the retracted position. When the shape measurement position of the shape measuring device is located on the downstream side of the main shaft, the rim flange lubricant provided at the tire chuck position of the loading means can be brought closer to the main shaft side on the upstream side of the main shaft, and as a result, it can be prevented. The long stroke of the moving means. Further, when the retracted position is on the upper side or the lower side of the shape measuring position of the shape measuring device, and the conveying means is provided on the same side with respect to the shape @ position and the vertical direction, the tire can be shortened from the shape measuring position or the uniformity measuring position to the setting. The distance from the tire handling height of the loading/unloading means can shorten the time during which the tire is carried into the main shaft or suppress the movement of the feeding means and the long stroke. The measuring unit preferably measures the outer shape of at least two side bead portions of the outer shape of the tire by a slit-like laser. With the use of the non-contact type shape measuring device using the slit-like laser, the two-dimensional measurement of the outer shape of the tire can be accurately performed in a short time. Further, the tire inspection method according to the present invention includes the steps of preparing a first tire transporting means and a second tire transporting means for transporting the tire, and providing the tires to be rotatably supported by the transport path of each of the tire transporting means. a main shaft, and a step of moving back and forth between the main shafts to contact the drums of the tires mounted on the respective main shafts; the drums are in contact with the tires of one of the main shafts during contact with the tires mounted on one of the main shafts The step of uniformity; the step of measuring the dynamic balance of the tire attached to one of the main shafts and the step of replacing the tire with a new tire during the period from the one spindle to the return of the drum. More preferably, the measurement of the outer shape of the tire in contact with the tire mounted on the main shaft may be performed. Further, the tire inspection method according to the present invention may further include: a step of preparing a first tire transporting means and a second tire transporting means for transporting the tire; and providing a transporting path for allowing the tires to be rotatably supported by the respective tire transporting means The upper spindle is provided with a step of reciprocatingly moving between the spindles of the spindles to contact the drum of the tires mounted on the respective spindles; the drum is measured for contact with one of the spindles of one of the spindles a step of uniformity and shape of the tire; a step of measuring the outer shape of the tire attached to the other main shaft by using a shape measuring device that measures the outer shape while the drum is being separated from one of the main shafts to return; and The step of replacing the tire attached to the one main shaft with a new tire while the drum is separated from the main shaft to the return. The method shown above can perform high-efficiency tire inspection for the rationalization of inspection equipment and for multiple items.
