BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire removing device in a tire forming machine for removing a completed tire from a tire forming machine.

As a manufacturing method of a radial tire, the method of manufacturing a cylindrical tire with a 1st stage apparatus, making it annular with a 2nd stage manufacturing apparatus, and combining a breaker and a face sphere on the outer side is known. As the second stage manufacturing apparatus, various kinds are known.

Normally, the removal of the finished green tire from the second stage manufacturing apparatus is performed by the worker's hand work, but when the tire is used for a truck or a bus, the tire is large in size and heavy. .

For that reason, the same thing as published in Japanese Unexamined Patent Application Publication No. 55-35255 has been proposed for the purpose of improving worker's efforts.

This allows the breaker and the spherical body conveying mechanism to be gripped from the outside by grasping the completed grease tire from the outside, and the conveying mechanism for removing the tire from the drum is the breaker and the spherical sphere. Since it is necessary to transfer and position it precisely with respect to the annular tire frame on the drum, a simple structure with as little freedom as possible to rotate, swing or swing is desirable. There was a problem that special care must be taken.

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and an object of the present invention is to provide a tire molding machine which can automatically pull out the finished grease tire to the outside of the tire molding machine without degrading the accuracy of the breaker and the spherical concrete conveying mechanism. It is to provide a tire removing device.

A breaker / vertical spherical transfer mechanism, characterized in that it is mounted to a movable mechanism that is movable between two positions with a discharge position, and has a support mechanism for supporting the ear portion of the grip tire gripped from the outside to the transfer mechanism from the inside. The completed grease tire, which has been gripped from the outside, is supported by the support mechanism from the inside at the predetermined position on the moving line of the transfer mechanism, and is moved to the completed grease discharge position of the moving mechanism equipped with the support mechanism. According to the movement, it can be automatically taken out of the molding machine.

Therefore, the operator can be freed from the tire unloading work, and in the meantime, he can concentrate on the preparation of the more accurate breaker and the spherical body and improve the operation rate of the machine. It is possible to make a simple structure without the need to transfer the breaker / surface spherical sphere with high precision.

Next, the embodiment shown in FIG. 5 will be described.

This tire extractor is applicable as a tire extractor g 'for the second stage manufacturing apparatus shown in FIG. 2, wherein (1) to (9) are the same as those shown in FIG. 3 and FIG. Similarly, the disk 3 is provided with a projection 30 at its place, and a boss 31 is mounted on the projection 30, and a shaft 33 fixed to the boss 31 is provided on the floor. (34) and (35) are mounted on a bearing (32) mounted on a rotating material so as to be rotated by a suitable driving device.

The operation is explained next.

First, the case where the tire extracting apparatus shown in FIG. 3 is combined with the 2nd stage manufacturing apparatus shown in FIG. 1 and FIG. 2 is demonstrated.

When assembly of the green tire T is completed on the drum device (a) or (a '), the transport port (e) or (e') moves to the drum device (a) or (a ') position, and the tire (T) G) from the outside. The drum device (a) or (a ') is then retracted so that the tire (T) is led to the conveying port (e) or (e'), during which the tire discharging device rotates around the vertical axis (13) and the axis (5) It stops at the position which becomes on the center axis line of drum apparatus (a) or (a '). At this time, the segments 1 and 2 are shrunk so as to be sufficiently smaller than the inner diameter of the ear of the tire T.

Further, the segments (1) and (2) do not collide with the tire take-off device by moving the carriage (e) or (e ') that holds the tire (T) from the outside and moving on the track (f) or (f'). When stopped at a predetermined tire disengage position, which is convenient for gripping the ear portions on the left and right sides of the tire T, the cylinder 9 is operated to place the sleeves 6, links 7 and 8, and the segment 1 And (2) is extended radially outward, and the ear part of the tire T is gripped from the inside. When the tire is gripped by the segment, the outer gripping of the tire by the carriage e or e 'is released, and the tire T is led to the take-out device.

After the conveying port e or e 'having guided the tire T is moved toward the drum device a or aa (inversely, the dispensing device may be moved in the axial direction), the tire dismounting device is moved on the vertical axis 13 Rotate around, stop above the predetermined tire discharge position away from the manufacturing apparatus, and then rotate the shaft 11 and the disc 3 to the top of the tire to make the tire T horizontal. Next, the tire T is dropped and discharged by shrinking the segments 1 and 2 by the cylinder 9.

At this time, if the tire conveying apparatus which can be lifted and lowered in the horizontal state is prepared, the fall of the tire's own weight can be alleviated, and the shaft 11 can be moved up and down instead. While the tire take-off device is discharging and discharging the tire as described above, the conveying port (e) or (e ') is placed in the drum device (c) or (c') position for conveying the breaker and the tread body for the next tire. You can go to

In addition, it goes without saying that the rotational motion around the shaft 11 is unnecessary in the above-described operation when the tire is conveyed in an upright state when the tire is transferred from the discharge position to the next step.

In addition, the tire extracting apparatus shown in FIG. 4 is similar to that shown in FIG. 3 except that the movement between the tire receiving position and the tire discharging position from the conveying port is performed by rotating around the horizontal axis 23. The tire can be removed by the function of.

In addition, the tire removing apparatus shown in FIG. 5 is applicable to the second stage manufacturing apparatus of the structure shown in FIG. 2, and the conveyance port e 'removes the tire tire T from the drum apparatus a'. The tire disengagement device rotates around the horizontal axis 33 and stops at the position where the shaft 5 becomes on the center axis line of the drum device a 'while performing the operation. After receiving the tire tire T by (e ') and receiving the tire, the tire is rotated around the horizontal axis 33 and stopped at the predetermined tire discharge position. In this case, the dispensing apparatus is stopped at the position where the tire is in a horizontal state, and the segments 1 and 2 are contracted as they are so that the tire T can be released.

In this case, it will be easily understood by those skilled in the art that the movement of the tire take-off device to the tire discharge position is preferably performed for the purpose of increasing the production rate by waiting for the next cylindrical green tire to be supplied to the drum device.

As is evident from the above description, according to each of the above-described embodiments, an operator who works with the drum apparatuses (a) (a ') and (c) (c') needs to carry out the completed tire tire out of the apparatus. This operation can be performed automatically, thereby reducing the operator's effort, and at the same time, the operator can concentrate on the preparation of the more accurate breaker / surface spherical body, and further improve the operation rate of the manufacturing apparatus. have.

Moreover, since the conveyance port e or e 'does not need to rotate or oscillate, it becomes a simple structure only by moving in the axial direction of a drum, and can convey a highly accurate breaker / surface spherical body.

In addition, although the said embodiment demonstrated the case where all were performed to the 2nd stage manufacturing apparatus, also in the manufacturing apparatus which performs a whole manufacturing process by one apparatus, the drum apparatus (C) (C ') and the conveyance port (e) ( e '), it is possible to implement the same, and it will be understood that when the present embodiment is employed in the above two kinds of production apparatuses, the above embodiment is selected and employed according to the transfer means from the discharge position to the next step.
