Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for taking out a vulcanized tube tire, and more particularly to a method for taking out a vulcanized tube tire, in which the vulcanized tube tire is taken out from a vulcanization press and conveyed to a post-cure flake.

Generally, a vulcanized tire is taken out of a press mold of a vulcanization press machine and then transported to a post-cure flake.

Conventionally, various methods have been used to take out the vulcanized tire from the vulcanization press and convey it to the post-cure flake.

One of these methods, as described in Japanese Patent Publication No. 53-6680, is to push the tire take-out arm below the vulcanized tube tire in the press mold of a vulcanization press machine, and then insert the vulcanized tube tire into the tire. The tire is placed on the belt conveyor of the take-out arm, and then the Caro-cured tire is taken out from the press mold of the vulcanization press by the tire take-out arm and the belt conveyor, and transported to the post-cure flake.

Another method is as described in Japanese Patent Publication No. 46-11971, in which the caro-sulfurized tires are gripped and lifted by bead rings, and then placed on a gravity conveyor tilted at a predetermined angle by the movement of a cart. The vulcanized tube tire is then rolled on a powered conveyor and fed to the post-cured flakes.

The former method has the disadvantage that the weak vulcanized tire is deformed because a tire take-out arm having a belt conveyor is forced below the vulcanized tire.

In addition, when the vulcanized tire is pulled and placed on the belt conveyor of the tire take-out arm, there is a risk that the vulcanized tire may get caught in the vulcanization bladder, center post, etc. of the vulcanization press machine. In order to prevent this, a device for retracting the vulcanization bladder, center post, etc. into the press mold is required, which results in a drawback that the overall structure becomes complicated and large.

In the latter method, the vulcanized tire rolls on a gravity conveyor due to its gravity, so it is difficult to align the axis of the vulcanized tire with the axis of the post-cured flake, which often results in defects such as rim jamming. There was a drawback that tires were generated.

Moreover, the supply of the vulcanized tube tires to the post-cure inflator is unstable, and there is also a drawback that the work efficiency of supplying the vulcanized tube tires to the post-cured inflate is reduced.

The present invention has been made in view of the above drawbacks, and includes a first step of gripping a vulcanized tube tire in a vulcanization press machine with a gripping member, and a step of lifting the gripping member while gripping the vulcanized tube tire. A second step of separating the vulcanized tube tire from the press mold of the vulcanization press machine, and a second step of separating the vulcanized tire from the press mold of the vulcanization press machine, and moving the gripping member while holding the egg-cured tire so that the axis of the vulcanized tire is parallel to the axis of the post-cured flake. a third step of tilting until the
A fourth step of moving the gripping member in the tilting direction until the axis of the vulcanized tire becomes coaxial with the axis of the post-cured flake while keeping the gripping member tilted. It's a method.

An approach/separation mechanism 56 is configured to synchronously approach and separate 7°48.47' and 48' from the center of curvature of the vulcanized tire T.

By operating this approach/separation mechanism 56, the gripping members 47, 47'
, 48, 4 are brought close to the center of curvature of the Calo-sulfurized tire T, thereby gripping members 47, 47', 4
8 and 48' can grip the vulcanized tire T while centering it.

Next, the effect will be explained.

First, in the preparation process, the press mold 2 of the vulcanization press machine 1 is opened, and the vulcanized tire T is placed in the press mold 2.

At this time, the guide rails 14 and 14' are connected to the press die 2.
The movable frames 22 and 22' are located at a predetermined distance behind the press die 2 between the guide rails 14 and 14'.

Also, at this time, the piston rod 53 of the cylinder 52 protrudes, and the guide shafts 16 and 16' and the shafts 19 and 1
9' are located at the lower ends of the guide grooves 6, 6' and the vertical grooves 7, 7', respectively.

Next, in the first step, a drive sprocket (not shown) is driven to rotate.

As a result, the moving frames 22, 22' are connected to the chain 3L.
31' and moves to just above the Karo sulfurized tire T.

Next, actuate the cylinder 52 so that its piston rod 53
stand out.

As a result, the rope 54 is pulled by the tensile force of the spring 55, and the rotating shafts 36, 36' rotate synchronously via the boots IJ-39, 51, 50, 39, 49.

At the same time, the gears 38, 40. 38', 40' are meshing with each other, so the rotating shafts 37, 37'
also rotate in sync.

As a result, the swinging arms 4L42, 41', 42' swing around the rotation axes 36°37. The centering pins 43, 44, 43', 44' are oscillated to approach the center in synchronization, and the centering pins 43, 44, 43', 44' come into contact with the outer peripheral surface of the vulcanized wheel T.

At this time, the grip plates 45, 46, 45', and 46' are inserted between the lower end surface of the vulcanized tire T and the press mold 2.

As a result, the vulcanized tire T has a centering pin of 43°4.
4, 43', 44', and is gripped by the cooperative action of gripping plates 45, 46, 45', 46' and centering pins 43, 44, 43', 44'.

Next, in the second step, a drive mechanism (not shown) is operated to move the crank discs 11 and 11' onto the eccentric shaft 1.
2 and 12' are respectively rotated by a predetermined angle in synchronization with each other as rotation centers.

As a result, the guide shafts 16, 16' and shafts 19, 19' are guided upward by the vertical portions 8, 8' of the guide grooves 6, 6' and the vertical grooves 7, 7, respectively, via the links 17, 17'. Move to.

At this time, the support plates 13, 13', the guide rail 14
, 14', moving frame 22°22', approach/separation mechanism 5
6 and the gripping members 47, 48, 47', 48' are lifted upward as one.

That is, the vulcanized tire T is held by the gripping members 47, 48, 47.
It rises while being held by ', 4B' and moves away from the press mold 2 of the vulcanizing press machine 1.

Next, in the third step, the drive mechanism is operated to further rotate the crank disks 11, 11'.

As a result, the guide shafts 16, 16' move guided by the horizontal parts 10, 10' and the inclined parts 9, 9' of the guide grooves 6, 6', and the shafts 19, 19' move in the vertical grooves 7, 1. You will be guided and move downwards.

As a result, the support plates 13, 13', the guide rail 14
, 14', moving frame 22, 22', approach/separation mechanism 5
6 and the gripping members 47, 48, 47', 4B' are integrally inclined to be perpendicular to the axis of the post-cure flake 4.

That is, the vulcanized tire T is held by the gripping members 47, 48, 47.
While being held by ', 48', the vulcanized tire T is tilted so that its axis becomes parallel to the axis of the post-cured flake 4.

Next, in the fourth step, a drive sprocket (not shown) is driven.

As a result, the moving mechanism 3 is pulled by the chain 3L31'.
3 moves in a direction away from the press mold 2.

That is, the vulcanized tire T is held by the gripping members 47, 48, 47.
', 48' and moves in the direction of inclination until the axis of the vulcanized tire T becomes coaxial with the axis of the post-cured flake 4 while being inclined.

Next, the post-cure flakes 4 are activated.

As a result, the vulcanized tire T is supplied to the post-cure flakes 4.

In the manner described above, the vulcanized tire T is taken out from the press die 2 of the vulcanization press machine 1 and conveyed and supplied to the post-cure in router 4.

This operation is repeated thereafter.

Since the method of the present invention is carried out as described above, it is easy to align the axis of the vulcanized tire with the axis of the post-cure inbreak, and the occurrence of defective tires such as rim chewing is reduced.

Further, since the vulcanized tire can be stably supplied to the post-cured flakes, the work efficiency is improved.

Furthermore, since the tire removal arm is not pushed under the vulcanized tire, the vulcanized tire will not be deformed.

Furthermore, there is no need to retract the vulcanization bladder or the like, and the device can be made smaller.
