に発揮されない。<Problems to be Solved by the Invention> However, in the conventional automatic rim changing device for the tire uniformity machine described above, a plurality of rim assemblies for replacement are mounted on the rim changing cart 57 disposed below the uniformity machine, that is, inside the machine. Since the used rim assemblies that have been stocked and measured are exchanged for rim assemblies of different sizes in stock, it is easy to exchange the stored rim assemblies. In measurement work formats that use rim assemblies of many sizes that far exceed the carrying capacity of the cart, and in which the rim assemblies currently being stored are frequently replaced with other rim assemblies, unnecessary rim assemblies are replaced with other rim assemblies. The measurement operation must be stopped each time the rim assembly is manually replaced, and there is a problem in that the overall efficiency of the measurement operation is very low. Therefore, the inherent advantage of this tire uniformity machine, in which the locking means allows automatic exchange of the upper and lower rims to be performed accurately, quickly, and easily, is not fully demonstrated.

An object of the present invention is to provide an automatic rim changing device for a tire uniformity machine that fully exhibits the advantages of the above and further improves the efficiency of measurement work.

移動するリム搬送装置を備えたことを特徴とする。Means for Solving the Problems In order to achieve the above object, the automatic rim changing method and device for a tire uniformity machine of the present invention allows the rim assembly during measurement to be changed only outside the uniformity machine. This is a method in which all rim assemblies other than the rim assembly are stored, and any rim assembly stored outside is replaced with any other rim assembly other than the one being stored, as necessary, regardless of whether the measurement is being carried out or stopped. Further, the upper rim is removably fitted to the lower spindle which is removably connected to the elevating member of the elevating means provided below the upper spindle. A rim storage device that assembles and holds rims, includes means for holding the upper rim released from the upper spindle by the lower spindle or the lower rim, and holds a plurality of rim assemblies each including the lower spindle, the lower rim, and the upper rim. An automatic rim changing device for a tire uniformity machine, wherein the storage device is installed only outside the tire uniformity man, and the rim assembly is moved between the rim storage device and the measurement position of the tire uniformity man. It is characterized by being equipped with a rim conveying device that holds and moves the rim.

There is. When a size A tire is measured and replaced with an E size rim, the locking means of the upper spindle is first removed, and the rim assembly consisting of the A size upper rim, lower rim, and lower spindle is lowered by the lifting member. The upper end of the elevating member and the lower spindle are disengaged by further lowering, and the rim assembly is held in the rim transporter. Next, the rim conveyance device holding the A size rim assembly is
The A size rim assembly is moved from the measurement position to the relay position, and then moved to the empty storage portion of the rim storage device, and is fitted and stored in the empty storage portion of the rim storage device. Next, the rim conveyance device holds the E size rim assembly in the rim storage device, moves to the tire uniformity measurement position via the relay position in the opposite manner as described above, and lifts and lowers the E size rim assembly. Position it above the member and stop. Next, the elevating member rises, connects to and pushes up the E size rim assembly held by the holding part, and the upper rim fits into the lower end of the upper spindle and is locked by the locking means and installed. Complete.

て移動する。During the uniformity measurement, the tire T is moved by the rod 54a of the lifting cylinder 54 at the measurement position 0, as shown in FIG. 2.3.
It is attached to the upper and lower rims 48.59 between the upper and lower spindles 44.58 that are fitted together above the roller conveyor 3 by the protrusion of the roller conveyor 3, is filled with air, and is pressed by the load applying device 62 while being rotated to perform the Uniformidi measurement. . At this time, the rim conveyance table 5 is waiting on the rail 6.6 with the center of the rim storage hole 2I aligned with the central axis of the lifting cylinder 54, as shown in FIG. 2.3. When a tire of a certain size has been measured and is to be replaced with a rim of a different size, first the collet chuck 52 (the first
0. f1) is opened, the upper rim 48 is released from the upper spindle and integrated into the waiting assembly of the lower rim 59 and the lower spindle 58, and the assembly 20 is moved upward by the lowering of the rod 54a of the lifting cylinder 54. The rod 54a is fitted into the rim storage hole 21, and as the rod 54a is further lowered, the rod head 61 and the fitting recess 60 (to,
tt figure) is disengaged, and the assembly 20 is held on the rim conveyor 5. Next, the rim conveyance table 5 moves on the rail 6.6 to the relay position P by retraction of the rod 7a of the cylinder 7.

参照）。The rim lifter 9, which was waiting below this position, protrudes the lifting cylinder 240 and the rod 24a, and the rod head 25
is fitted into the fitting recess 60 of the assembly 20, and the assembly is pushed up (see Fig. 5), and the cylinder 11 is held in this state.
By the protrusion of the rod lla, the rim is moved on the rail IO, 10 to the take-out position Q above the empty rim storage hole 14 of the turntable 13 (see Fig. 6.7). Subsequently, the rim lifter 9 retracts the rod 24a of the lifting cylinder 24 to the bottom of the turntable, thereby lifting the assembly 20.
is fitted and stored in the rim storage hole 14 (see Figure 8.9).

着が完了する。Thereafter, the motor 32 of the rim storage device 12 is driven to rotate the turntable 13 so that the desired rim assembly to be taken out comes to the take-out position Q, and then the rod 24a of the rim lifter 9 is protruded to remove the desired rim assembly. The solid body is pushed up and held by the rim lifter 9. Contrary to the above, the rim lifter 9 moves on the rails to and 10 to the relay image HP by retracting the rod lla of the cylinder, and then moves the assembly being held onto the conveyance table 5 by retracting the rod 24a. Further, contrary to the above, the conveyance table 5 is moved on the rail 6.6 by the protrusion of the rod 7a of the cylinder above the elevating cylinder 54 of the unit 7-way machine body t, that is, to the measurement position O. Finally, the rod 54a rises with its head holding the new assembly so that the conical protrusion 49 at the upper end of this assembly fits into the lower end of the upper spindle 44, as shown in FIG. 10.2. While fitting into the mating recess 50, the locking metal fitting 5 at the tip of the conical convex portion 49
1 is locked by the collet 52 by the opening/closing operation of the collet 52 as the rod 47 protrudes and retracts, and the installation of the upper rim is completed.

でもよい。In the above embodiment, the rim conveyance device is comprised of a conveyance table 5 that reciprocates on the rail 6.6 and a rim lifter 9 that reciprocates on the rail 10.10 below the rail 6.6 and perpendicular thereto and moves up and down. However, it goes without saying that the rim conveying device is not limited to this. Further, the rod means of the upper rim is not limited to the above embodiment, and for example,
A hook type as shown in FIG. 4 of Japanese Patent No.-185619 may be used.
