Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a holding and feeding device for green tires used for loading.

An unvulcanized tire (hereinafter referred to as a green tire) is sealed in a mold. The conventional method for transporting green tires into the press for curing tires is: This is the so-called lower bead center first method in which the lower bead of the green tire is seated on the lower bead ring of the lower mold part first. According to this method. As shown in Figure 1, a green tire supported by a bladder inflated at extremely low pressure is unstable, and even the slightest non-uniformity of the bladder can cause it to tilt with respect to its central axis. There is. When attempting to seat the upper bead of a green tire by approaching the lower bead link, a seating error may occur.

In order to solve this problem, as shown in Fig. 2, the upper bead of the raw tire is seated on the double bead ring of the stopper mold part, and. It is desirable to perform shaving by inflating a bladder in a raw tire in which the F bead portion is supported by the lower bead link of the lower mold portion. However, with the conventional green tire carrying device, the green tire is held suspended by the upper bead part, the lower bead of the green tire is seated on the lower bead ring, and the suspended grip in the carry-in cage is released. After the tire is removed, the upper bead ring is moved closer to seat the upper bead of the raw tire, and an attempt is made to perform the 7-step ping operation as shown in Figure 2, but it does not work.

That is, as soon as the suspension grip by the carry-in device is released, the green tire will buckle and tumble as shown in FIG.

- In order to eliminate the two drawbacks, the applicant recently set the green tire gripping claws of the green tire carrying device upward (the conventional one faces downward), and grasps the lower bead of the green tire (the conventional one grips the green tire gripping claw upward). At the same time, each of the gripping claws is equipped with a movable support claw that supports the tread part of the green tire from below, and grips the lower bead part of the green tire at a position outside the press. At the same time, the tread part is supported from below, and in this state, the raw tire is carried into the press, and the upper bead part of the raw tire is seated on the upper pead ring of the upper mold. part of the upper mold part
After suspending and gripping the green tire with a bead gripping device and lowering the green tire, the lower bead of the green tire is seated on the lower bead ring of the lower mold part, and then the Prada is inflated inside the green tire as shown in Fig. 2. I would like to suggest something like this.

According to this method, since the green tire is suspended above the center of gravity, it is convenient when the lower bead ring is inserted into the lower pead of the green tire.

1/L7, when picking up a green tire from a green tire carrying device or at a position outside the press, a worker must pick up a heavy tire and place it on the soil-facing gripping claw of the green tire carrying device. When a green tire weighs nearly 1,000 kg, such as a radial tire for a truck or pass, it becomes difficult for an operator to install the green tire by hand. However, the raw tires on the automatic tire delivery vehicle are placed on the two-faced claws by an automatic installation device equipped on the automatic delivery vehicle.
If you place them directly, the number of green tires that can be prepared in advance for the 9th vulcanization while the vulcanizing press is vulcanizing is 2 (when using a 2-chamber type vulcanizing press), and l When there is only enough room for cycles and multiple presses are installed, the automatic green tire delivery and automatic installation equipment has to move around busily, and the number of presses that can be handled by one automatic equipment is limited. One thing is true.

For this reason, the present applicant has filed a separate application in which the upper bead of a green tire placed on 16 green tires is gripped by a green tire carrying device and then held to an appropriate height. Two raw tires” 1 down] IY! Flip it so that
By carrying it into the press, you can get 4 raw tires in front of the press for 7 yen! Suggest things that you can do (be prepared),
ing.

However, the green tire loading device □□ requires vertical movement, rocking rotation for loading, and reversal movement.
