The controller 1a
It comprises a data receiving means 46, a calculating means 34, a storage means 36, a mounting control means 38, and a data sending means 47.

The calculating means 34 obtains, for each type of the tire T, the air injection time of each tire T at which the mounting air pressure for mounting the tire T on the rim can be obtained from the amount corresponding to the volume of the tire T. The storage means 36 stores in advance the calculated air injection time for each type of tire T. The ID data is transferred to the data receiving means 46 after the operation of the tire mounters 5 and 5 is completed. The mounting control means 38
Is based on the data input from the data receiving means 46,
The air injecting means 30 is controlled according to the type of the tire T, and the tire T
The ears are set by injecting high-pressure air into the tire T and setting the inside of the tire T to the mounting air pressure. The data sending means 47, after completion of the air filling work by the pre-injector 1,
The data in the mounting control means 38 is sent to the balance measuring device 3 in the subsequent process.

The disk plate supply device 2 shown in FIG. 1 includes a disk plate storage shelf 8, a take-out mechanism 9, and a controller 2.
a. A plurality of disk plates are stored in a storage box (not shown) for each model. The disk plate storage shelf 8 is set up and down so that a plurality of types of storage boxes can be taken out by a take-out mechanism 9 equipped with a conveyor. It is arranged and stored on the left and right. The take-out mechanism 9 takes out the storage box from the storage shelf 8 and conveys it under the conveyance paths 20, 20 to an extraction port 10 formed inside. The storage shelf 8 and the take-out mechanism 9 form a kind of three-dimensional warehouse. The take-out port 10 is provided with a take-out sensor 11, which detects that the disk plate has been taken out of the storage box. The operator takes out the disk plates one by one from the storage box conveyed to the take-out opening 10. When the removal sensor 11 detects that the disk plate has been removed by the operator, the removal mechanism 9 causes the storage box to exit the outlet 10.

Although not shown, the controller 2a of the disk plate supply device 2 has a pre-injector 1 shown in FIG.
Similarly to the controller 1a of the above, it has a data receiving means, a data sending means, and a storage means, and further has a control means for controlling the air driver and the counter 13. In the storage means, the type of disk plate, the number of disk plates and the number of bolts are stored, and according to the data,
Control means controls the air driver and counter 15 located inside the assembly line L1. The data receiving means is
Receives ID data from the tire mounter 5 in the previous process,
The data transmission means transmits the ID to the balance measuring device 3 in the subsequent process.
Send data.

The data receiving means of the controller 2a includes:
The ID data is sent from the tire mounter 5, and the storage box is taken out from the storage shelf 8 while the wheel body with tire RT is injecting air to the mounting air pressure by the pre-injection machine 1; B, the ID data of the succeeding wheel body RT with a tire following the tire mounter 5
And the corresponding storage box is waiting on the way. If the same type is continuous, it is once withdrawn from the outlet 10 and waits halfway.
Therefore, the time until the next removal is shortened because the storage shelf 8 does not return. In the case where two disk plates are mounted, the storage box is not withdrawn from the outlet 10 until the removal sensor 11 detects that two sheets have been removed. Therefore, the worker only has to perform the work of taking out one sheet at a time.

Inside the assembly line L1 at the brake disk assembly position C, a storage box 12 for screws for mounting a disk plate is provided with an air driver and a counter 1.
5 is provided. The air driver and the counter 15 are controlled by the controller 2a,
The number of screws required for the corresponding disk plate is displayed on the counter according to an input from the controller 2a, and the counter display is reduced every time one air driver is tightened. The operator only needs to perform bolt fastening work until the counter becomes zero. When this step is completed, the worker manually moves the wheeled wheel main body RT to a predetermined position on the free roller.

The balance measuring device 3 measures the balance of the tire wheels. That is, the balance measuring machine 14
Is a state in which the wheel body with a tire RT is gripped by a lift and separated from the transport paths 20, 20.
While rotating T, measure the balance. The workers
Operation panel 1 provided on work space S1 side of transport path 20
The switch 5 is pressed to start the balance measuring device 14. The measured wheel main body with tire RT is sent to the pressure adjusting and balance weight caulking position E by the transport roller 16.

Controller 3a of balance measuring device 3
Although not shown, similar to the controller 1a of the pre-injector 1 shown in FIG. 2, the controller has a data receiving unit, a data transmitting unit, a calculating unit, and a storage unit. Means. The storage means stores the weight of the balance weight to be caulked, and the like, and can also store information from the balance measuring device 14. The calculating means calculates the balance weight corresponding to the tire wheel from the information from the balance measuring device 14 input from the storage means, and inputs the data to the storage means again. According to the data, the control means displays the weight of the balance weight on the controller 3a. The data receiving means receives the ID data from the disk plate unloading device 2 in the preceding process or the pre-injection machine 1 in the further preceding process, and the data sending device is the pressure regulator 4 or a discharge line for discharging the completed tire wheel thereafter. Send data to

The operator looks at the weight of the balance weight displayed on the controller 3a at the pressure adjustment and balance weight caulking position E, and applies the corresponding balance weight from the weight box 17 arranged inside the assembly line 1. It is taken out, caulked with a tool into the connection part of the spoke and the rim, and the air pressure is adjusted (pressure adjustment) by the pressure regulator 4.

The pressure regulator 4 has the same configuration as the pre-filler 1. However, unlike the pre-injector 1, the high-pressure air is mainly extracted and adjusted to the set air pressure. The tire wheel completed after the pressure adjustment and the caulking of the balance weight are completed is carried out by the bogie 19.
