A carry-out conveyor control means 39 is provided to control the driving of the carry-in conveyor C1 and the carry-out conveyor C2, respectively.

The computer 30 has an XYZ coordinate map storage means 31.
Numeral 31 sets a rectangular space coordinate (XYZ coordinate) based on the X-axis, Y-axis, and Z-axis in the space of the intermediate storage location S, and stores an XYZ coordinate map indicating the arrangement state of the tire T.

In the XYZ coordinate map, the type of the tire T is stored as a set together with the arrangement position of the tire T. A display label for identifying the tire is attached to the outer surface of the bead portion of the manufactured tire T, and the display label attached to the tire T is read by the barcode reader 22 disposed in the middle of the carry-in conveyor C1. The type identification means 36 identifies the type of the tire T.

The reading of information such as the tire size of the tire T may be performed on the carry-in conveyor C1 as described above, or may be performed on the upstream side of the carry-in conveyor C1.

The origin of the XYZ coordinate axes may be set at any position in the intermediate storage location S. For example, as shown in FIGS. 1 and 2, the center of the tire T at the loading position downstream of the loading conveyor C1 is defined as the origin 0. Set to. All of the tires T arranged in the intermediate storage location S are stored in the XYZ coordinate map storage means 31 with their XYZ coordinates and tire types being combined.

Based on the information stored in the XYZ coordinate map storage means 31, the computer 30 determines the placement position of the loaded tire T and the unloading means for confirming the mounting position of the unloaded tire T. The tire position checking means 33 is provided.

The tire information is input from the barcode reader 22 to the computer 30, and information such as the size of the rim currently used in the uniformity inspection machine U is input from the rim information input means 40.

The tire is input to the tire type identification means 36, the type of the tire is identified, and the unloading / storage selection means 37 is a tire which is unloaded as it is based on the tire type identification information and the rim information from the rim information input means 40. Or the tires to be stored temporarily.

If the loaded tire T is of a type corresponding to the rim currently used in the uniformity inspection machine U based on the tire type identification information, the tire is directly inspected and is taken out without being stored. It is determined that there is a tire, and if it is of a type that does not correspond to the rim, it is determined that the tire is to be stored because it is not in an inspectable state.

When the loading position determining means 32 receives a signal instructing storage of the tire T from the unloading / storage selecting means 37, the tire position stored in the XYZ coordinate map storage means 31 from the identification information on the tire T to be loaded is received. The placement position of the tire T is determined based on the arrangement state of T, and the placement position information is output to the loading drive control means 34.

The carry-in drive control means 34 controls the drive of the X-axis motor 11, the Y-axis motor 12, the Z-axis motor 13 and the chuck motor 14 based on the placement position information, and carries in the carry-in conveyor C1. The tire T is gripped, lifted, moved to the determined mounting position, and mounted.

The method of determining the position of the tire T to be placed in the intermediate storage location S by the placement position determining means 32 is based on the type of the loaded tire T. When the tire T is placed at any position of the storage location S, the vicinity of the same position or on the mounted tire T is determined, and the tire T of the same type does not exist in any of the intermediate storage locations S. In the case where the specified number is already placed as one block, an arbitrary position in another empty space is selected. Therefore, tire T
Blocks are configured collectively for each type and placed.

The carry-in conveyor C1 is driven by the carry-in conveyor control means 38 to sequentially carry in each kind of tire T,

When the tires T are placed on the unloading conveyor C2, the unloading conveyor control means 39 drives the unloading conveyor C2 to supply the tires T to the uniformity inspection machine U, where the tires T are fitted to the rim and uniformity measurement is performed. Done.

If the tire T carried into the intermediate storage location S as described above is of a type that is not in a testable state, the tire T is classified and placed at an arbitrary position in the intermediate storage location S and temporarily stored. However, in the case of a type of tire that can be inspected, it is placed at the upstream end position of the unloading conveyor C2, which is the unloading position, and supplied directly to the uniformity inspection machine U.

The above operation is performed completely automatically without any manual operation, and the tire T is efficiently supplied to the uniformity inspection machine U. When the uniformity inspection machine U replaces the rim in order to inspect another type of tire T, new rim information is input from the rim information input means 40 to the computer 30.

Even after the rim has been replaced, the carry-in conveyor C1 is not used.
As described above, when the tire T is loaded, the type is identified by the tire type identification means 36 as described above, and the tire is directly inspectable by the unloading / storage selection means 37 and is temporarily stored without being in the inspectable state. The tires are sorted out and carried out for uniformity inspection or stored in the intermediate storage location S.

When the rim is replaced and a tire of the type corresponding to the new rim is stored in the intermediate storage location S, the unloading tire position confirmation means 33 is provided by the rim information input means.
Input rim information from 40 and store XYZ coordinate map
Based on the arrangement information of the tires T in the XYZ coordinate map stored in 31, the position of the tire T to be carried out in a testable state corresponding to the rim is confirmed, and the position information is output to the carry-out drive control means 35.

The carry-out drive control means 35 is configured to control the X-axis motor 11, Y-axis motor 12, Z-axis motor based on the position information.
The driving of the chuck 13 and the chuck motor 14 is controlled to grip the tire T placed at the position and move to the upstream position of the unloading conveyor C2, which is the unloading position, and place it thereon. Then, the unloading conveyor control means 39 drives and controls the unloading conveyor C2 to supply the tire T to the uniformity inspection machine U.

When there is a tire T that is ready to be inspected in the intermediate storage place at the same time as the loading of the tire T that is ready to be inspected, it is possible to preferentially pick up the tire T closer to the chuck 9. Good.

In the case where the type of the tire T is newly added, it is not necessary to expand the equipment and the installation space, and the existing intermediate storage space S can be used as it is, and can be flexibly dealt with. It does not take.

According to the above-described tire storage method, even when the same type of tire T is stacked on the already mounted tire T, the same XY coordinates of the chuck 9 holding the tire T can be used. It can be stacked straight up with its center axis aligned, and there is no risk of collapse.

All the tires T thus loaded, sorted and placed have their XYZ coordinate positions along with the type of the tires.
It is stored in the XYZ coordinate map storage means 31 as a YZ coordinate map. Here, the Z coordinate corresponds to the height of the tire T and indicates a larger value as the tire T in the upper layer stacked.
