The lifter 30 is provided with a detector (not shown) for detecting the presence or absence of the bead 2 in the storage portion 12 of the carriage 3.
The reciprocating drive of the lifter 30 by the orthogonal biaxial feed mechanism 31 is controlled by the signal of the detector to selectively position the lifter 30 in the housing portion 12 without the beads 2.

For example, a reflection type sensor is used as the detector, which is attached in the vicinity of the bead feeding port 36 of the lifter 30 to control the rotational drive of the motor of the orthogonal biaxial feeding mechanism 31 (not shown). When the detector detects that the lifter 30 has reached the housing portion 12 in which the bead 2 is not housed, the controller stops the rotational drive of the motor and positions the motor. It is preferable to use an AC servomotor as this motor.

As shown in FIGS. 3 and 6, the lifter 30 is

mm) so that the bead 2 does not wobble while the lifter 30 is moving, and when the bead 2 is fed into the storage part 12, the bead 2 rolls smoothly without hitting the vertical partition plate 14 at the bead feed port 16. To

The operation of the automatic bead loading apparatus constructed as described above will be explained. As shown in FIG. 3 by the solid line and the phantom line, the stocker 1 with the beads 2 suspended is the carriage 3 The stocker 1 swings so that the bead 2 is parallel to the storage portion 12 of the trolley 3 fixed at the predetermined position.

Thereafter, as shown in FIG. 2, the chuck 23 positioned on the bead 2 descends as shown in FIG. 6, grips the bead 2 and ascends, and then advances to the lifter 30 waiting at a predetermined position. Remove bead 2 from stocker 1 and wait for lifter 30 to pick up bead 2. At this time,
The pushing roller 43 of the lifter 30 stands by on the side opposite to the bead delivery port 36.

Next, the lifter 30 moves up to the bead 2 suspended by the chuck 23 and approaches the bead 2, and then the chuck 23
23 releases the bead 2 and drops it into the bead holding portion 42 (in a state where the gap is widened) of the lifter 30. The stocker 1 from which the bead 2 has been removed returns to the state shown by the solid line in FIG. 3 and waits for the next bead 2 to be hooked.

After the bead 2 is received by the lifter 30, the sub-upright guide 38 approaches the main upright guide 37, and the shaft member 47 becomes horizontal to prevent the bead 2 from falling. Next, the lifter 30 on which the bead 2 is placed is stored in the storage portion 12 of the carriage 3.
The process proceeds while checking whether or not the bead 2 is contained in the container by the above-mentioned detector, and stops in the storage section 12 in which the bead 2 is not contained.

After that, the shaft member 47 becomes vertical as shown by the imaginary line, and the pushing roller 43 pushes the bead 2 toward the trolley 3 and rolls it so that it is loaded in the storage section 12. By repeating the above operation, the beads 2 are automatically and sequentially loaded on the carriage 3. The loaded dolly 3 is transported to the next step (for example, a bead apex assembly device).

The present invention is not limited to the above-mentioned embodiments, and the design can be freely changed without departing from the gist of the present invention. For example, hang multiple beads 2 on stocker 1,
The chucks 23 may be taken out one by one, and the chucks 23 may be lifted and lowered using various linear reciprocating drive mechanisms other than the cylinder 27. In addition, the stopper mechanism 40
In this case, it is also possible to reciprocally drive the shaft member 47 only in the horizontal direction to block / open the bead delivery port 36.

Further, as shown in FIG. 7, the bead 2 held by the chuck 23 in a suspending manner and taken out from the stocker 1 is rotated by 180 ° about the vertical axis H about the vertical axis H. The reversing mechanism 48 for reversing may be provided in the first delivery means 4.

In the illustrated example, the chuck 23 is connected to the rotary actuator 49 via the coupling 50 to form a reversing mechanism 48, and the chuck 23 is rotated 180 ° by driving the rotary actuator 49. The rotary actuator 49, the coupling 50, and the chuck 23 are
The cylinder 27 (see FIG. 2) raises and lowers integrally. The reason for providing the reversing mechanism 48 in this way is as follows.

That is, the dolly 3 is set in the bead apex assembling device in the next step, and the dolly 3 is moved to the bead 2
If the bead 2 to be supplied to the bead apex assembly device is a tubeless whose cross section is not symmetrical as shown in the figure, the supply direction will be 1
Since it is opposite by 80 °, the bead 2 is loaded by the reversing mechanism 48 when the bead 2 is loaded on the trolley 3 so as to prevent such a situation.
This is for reversing. In this case, the rotation of the chuck 23 can be freely performed by using various rotary driving machines such as a motor other than the rotary actuator 49.
