If the hanger 10a already has the raw tire 3a at the time of detection by the actuation detector 21a, the checking detector 22a confirms that the raw tire 3a is present, so the lifter 4a does not act.

When the hanger 10a on which the raw tire 3a is hung reaches the front of the unloading device 5, the detected portion 16a of the hanger 10a is detected by the detector 27a among the identification detectors 27a to 27d. On the other hand, since the confirmation detector 28 confirms that the raw tire 3a is present, the unloading device 5 is activated by this and the hanger 10a is activated.
While dropping the raw tire 3a on the feed conveyor 6,
The type of the molding machine 2a to 2d used to mold the raw tire 3a is stored in the control unit 30.

At the time of unloading, first, the raw tire 3a is clamped from the left and right by the clamp tool 25, and then the parallel link mechanism 24 is swung to the lower side at a speed faster than the moving speed of the hanger 10a, so that the raw tire 3a is moved to the hanger 10a. Remove from the front of the hook part 12. Then, after the clamp tool 25 is laid down on the feed conveyor 6,
The clamp tool 25 is expanded and transferred on the feed conveyor 6.

The unloaded green tire 3a is sent by the feed conveyor 6, and when it reaches below the paint machine 7, it is painted by the paint machine 7 and then sent to the sorting conveyor 8. And
Since the raw tire 3a is to be sent to the loading device 9a,
When the detector 45a detects the raw tire 3a, the cylinder 44 is operated by a signal from the control unit 30 to convey the conveyor belt.
Raise 38a. Then, the raw tire 3a becomes the conveyor roller 3
It is sent from 7 to the loading conveyor 57 of the loading device 9a by the floating conveyor belt 38a and is stored in the tire receiving stand 56 of the loading cart 48. Therefore, when unloading, the hanger 10a
The type of the raw tire 3a can be automatically identified and can be used as information for subsequent sorting. Moreover, since a series of work can be automatically performed, work efficiency is improved and labor saving can be greatly promoted.

In addition, although an automatic loading device is illustrated in the embodiment, the invention is not limited to this.
