d can be loaded onto a rack vehicle (not shown).

Next, the operation will be explained. The trolley conveyor 1 rotates in the direction of the arrow in FIG. Therefore, the detected part 16a is now placed at the top.
When the empty hanger 10a with the attached hanger passes, the operating detectors 21a to 21d have different heights, so none of them operate. However, when it reaches the position of the actuation detector 21a, since the heights are the same, the detected part 16a is detected and the actuation detector 21a is activated, so the lifter 48 is actuated and the molding is performed by the forming 41I2a. raw tire 3a
is raised to the height of the hook portion 12 as shown by the imaginary line in FIG. When the hanger 10a passes over the lifter 4a, the green tire 3a is hooked onto the hook portion 12 and conveyed to the unloading device 5 side in a suspended state. Therefore, among the many hangers 10a to 10d, a specific hanger 1 determined by the position of the detected portion 16a is selected.
Only the hanger 10a can be automatically selected and the green tires 3a can be successively hooked onto the hanger 10a. Note that if there is already a green tire 3a in the hanger 10a when the operation detector 21a detects the green tire 3a, the confirmation detector 22a detects the green tire 3a.
The lifter 48 does not operate.

When the hanger 10a hanging the raw tire 3a reaches the front side of the unloading device 5, the detected part 16 of the hanger 10a
Among the identification detectors 27a to 27d, the detector 27a works by detecting a. On the other hand, the confirmation detector 28 detects that the raw tire 3a
As a result, the unloading device 5 is activated, and the green tire 3a is dropped from the hanger 10a onto the feeding conveyor 6, and the green tire 3a is transferred to the molding machine 2.
The control unit 30 stores the type of molding made by any of a to 2d.

When unloading, first clamp the raw tire 3a from the left and right sides with the clamping tool 25, and then connect the parallel link mechanism 24 to the hanger 1.
The raw tire 3a is removed forward from the hook portion 12 of the hanger 10a by swinging it downward at a speed faster than the moving speed of the hanger 0a. Then, after the clamp tool 25 is laid down on the feed conveyor 6, the clamp tool 25 is expanded and transferred onto the feed conveyor 6.

The unloaded green tire 3a is sent by a feeding conveyor 6,
When reaching the lower part of the paint machine 7, the sort is sent to the conveyor 8 after being painted by the paint machine 7. Since the green tire 3a is to be sent to the loading device 9a, when the detector 45a detects the green tire 3a, the cylinder 44 is actuated by a signal from the control unit 30 to raise the conveyor belt 38a. . Then raw tire 3
a floats up from the conveyor roller 37 and conveyor belt 3
8a to the loading conveyor 57 of the loading device 9a, and is stored in the tire holder 56 of the loading truck 48. Therefore, at the time of unloading, the type of green tire 3a on the hanger 10a can be automatically identified, and the information can be used for subsequent sorting. Moreover, since the entire series of tasks can be performed automatically, work efficiency can be improved and labor savings can be greatly promoted.

In addition, although the automatic loading device is illustrated in the Example, it is not limited to this.

Further, in the embodiment, a contact type is used, but a non-contact type reading may be performed using optical or electromagnetic means.

Furthermore, a method may be adopted in which the positions of the green tires 38 to 3d are constantly grasped and sorted by mutual communication between the molding machines 28 to 2d, the trolley conveyor 1, and the paint machine 7.
