When the nozzle mechanism 57 is applied by spraying, spraying, or the like in a state where it is lifted by driving the lifting / lowering unit 1, the entire outer surface extends from the tread portion of the tire T to the shoulder portion and the sidewall portion. Arbitrary coating materials can be applied to the region. In addition, a coated material contains various substances, such as a mold release agent and an adhesive agent, for example, and forms, such as a liquid body, a powdery body, a granular material, are not ask | required. Moreover, you may apply | coat a coating material from the robot with the nozzle mechanism in which a three-dimensional movement is possible, and the fixed nozzle mechanism without a freedom degree.

Hereinafter, the operation of each mechanism until the applied material is applied to the tire T will be described with reference to FIGS. 1, 6, and 7.
The tire T transported horizontally on the transporting conveyor 6 reads a barcode indicating information of the tire T attached to the tire T by the barcode reader 61 and outputs the barcode to the control device 7 that outputs the information. The control device 7 outputs the application pattern of the tire T to the application robot 51 as the application mechanism 5 based on the output information and makes it wait. After passing through the bar code reader 61, the tire T is aligned by the pair of arm bodies of the aligning device 62 so as to be positioned at the center of the transfer conveyor 6, and is transferred from the transfer conveyor 6 to the coating conveyor 4. .

  When the tire T is transferred to the coating conveyor 4, the position sensor 63 detects the conveyed tire T and outputs a detection signal to the control device 7. The control device 7 that has received the detection signal calculates the drive timing of the rotary elevating mechanism 1 from the conveying speed of the belt conveyors 40 and 40.

  The tire T that has passed through the position sensor 63 is detached from the conveyance path by driving the rotary lifting mechanism 1. Specifically, the control device 7 outputs an ascending signal to the control valves 32 a and 32 b constituting the elevating unit 3 based on the calculation result of the drive timing. Based on the output signal, the control valves 32a and 32b open the flow path from the pressurizing pump 32 to the cylinder 31a, the hydraulic oil is pumped into the cylinder 31a, and the piston 31b starts to rise (see FIG. 6). When the piston 31b is lifted, the rim body 20 as a support body positioned above is fitted to the inner peripheral surface (bead portion) of the tire T from below the tire T placed horizontally so as to be stretched over the belt conveyors 40, 40.

  The height of the piston 31b that has started to rise is measured by the height sensor 36, and the height sensor 36 detects that the piston 31b has reached the rise limit position and outputs a rise stop signal to the control device 7. . The control device 7 outputs a switching signal to the control valve 32a based on the rising stop signal and outputs a drive start signal to the rotary motor 15 provided in the rotating unit 2.

  When the tire T supported by the rim body 20 starts rotating as the rotary motor 15 is driven, the coating robot 51 applies the coating on the outer surface of the tire T based on the tire T information input in advance from the standby position. Apply. As a result, the applied material can be applied uniformly regardless of the size of the tire T. The rotation number of the tire T is detected by a rotation sensor 14 provided in the rotation unit 2, and a rotation number signal is output to the control device 7. Based on the rotation number signal, the control device 7 outputs a rotation stop signal to the rotation motor 15 and outputs an application end signal to the application robot 51 when the predetermined rotation number is reached. Thereafter, the control device 7 outputs a switching signal to the control valve 32b. Based on the switching signal, the control valve 32b opens a flow path from the cylinder 31a to the oil tank 32f.

When the supply of hydraulic pressure to the hydraulic actuator 31 is released, the piston 31 b starts to descend due to the weight of the tire T and the tensile force of the return spring 38.
When the piston 31b starts to descend, the tire T returns from being removed from the rim body 20 when the lower surface reaches the same position as the height of the belt conveyors 40, 40, and over the belt conveyors 40, 40 again. It is conveyed by the application conveyor 4.
