Will reciprocate in the radial direction as shown by the arrow.

Then, in the elevating means 7, the piston rod 29a is connected to the substrate 22.
As shown in FIG. 2, the cylinder 29b of the cylinder mechanism 29 is connected to the upper frame 31 of the substantially gate-shaped holding frame body 30 standing upright on the mounting table 4. It is fixed.

Therefore, when the piston rod 29a reciprocates, the substrate 22 moves up and down, and the locking claws 5 ... And the upper opening / closing mechanism 6 move up and down. In addition, guide rods 32, 32 are erected on the substrate 22,

To do. A tensioner 69 is mounted on the mounting frame 70 of the mounting table 3 near the rotary shaft 38.

Thus, the mounting table 4 is provided with a first position A on which the deformed raw tire 1 is mounted and a second position B for correcting the raw tire 1 into a predetermined regular shape. Then, at the second position B, the lower bead portion locking claw 9 is arranged.

Also, the lower bead portion locking claw 9 is used as the upper bead portion locking claw 5.
And the upper bead portion locking claws 5 are arranged upside down.

Therefore, the lower opening / closing mechanism 10 for opening / closing the locking claw 9 also has the same mechanism as the upper opening / closing mechanism 6. That is, the substrate 45

A projection unit 61 for projecting light is provided on the upper surface of the rear frame 12b.
A light receiving portion 62 for receiving light from the projection portion 61 is provided on the upper surface, and a lower bead portion detecting means 67 is formed.

In addition, on the substrate 22, a projection unit on which light is projected toward the reflection plate 64 via the through hole 65 of the vertical wall 5b of one locking claw 5 and a light reception unit for receiving the reflected light from the reflection plate 64. An upper bead portion detection unit 63 including the above is provided. The reflector 64 is
It is attached to the back surface of the vertical frame 35 of the holding frame body 30.

Next, a method of using this device will be described.

First, as shown in FIG. 4A, the deformed raw tire 1 is attached to the first position A of the mounting table 4 manually or by mechanical means.
Place on rails 58, 58 of. In this case, the holding frame body 30 of the transport mechanism 8 is located at the second position B as shown in FIG. Next, the holding frame 30 in the second position B
Is driven to the first position A by driving the motor 37. In this case, as shown in FIG. 2, the mounting table 4 is provided with a limit switch 66 and the like to control the movement thereof. That is, the holding frame body 30 is moved from the second position B to the second position A, and the vertical frame 35 is moved to the limit switch.
When it contacts 66, the drive of the motor 37 stops and the holding frame 30
Movement stops. At this time, the axial center of the mounted raw tire 1 and the axial center of the upper opening / closing mechanism 6 substantially coincide with each other, and
The vertical movement of the locking claws 5 by the elevating means 7 is performed along the axis thereof.

Then, the piston rod 29a is extended to insert the closed locking claws 5 into the green tire 1 as shown in FIG. 4B, and as shown in FIG. Light is projected toward the reflector 64. Here, the upper bead portion detection unit 63, when not receiving the reflected light from the reflector 64,
The lowering is stopped and the upper opening / closing mechanism 6 is operated to open the locking claws 5 ... Therefore, when the reflected light is not received, the upper bead portion 2 is in a position corresponding to the locking claws 5, ... At this time, if the locking claws 5 are opened, the locking claws 5 ... The upper bead portion 2 is locked as shown by the phantom line in FIG. 4C.

Next, the raising and lowering means 7 raises the locking claws 5 ... And projects light from the projection unit 61 toward the light receiving unit 62.

Here, the lower bead portion detecting means 67 provided with the projecting portion 61 and the light receiving portion 62 is for stopping the raising of the elevating means 7 when the light receiving portion 62 receives the light from the projecting portion 61. Therefore, when the light receiving portion 62 does not receive light, the lower bead portion 3
Still exists between the projection unit 61 and the light receiving unit 62,
When 62 receives light, the lower bead portion 3 does not exist between the projection portion 61 and the light receiving portion 62. That is, the fourth
As shown in FIG. 6C, the light receiving unit 62 receives the light from the projecting unit 61 at a position where the lower bead unit 3 is elevated by a certain height above the upper surface of the mounting table 4, and therefore stops at that position. The rails 58, 58
Are provided with passage holes 73, 73 (see FIG. 5) through which light passes.

Next, in this state, the transport mechanism 8 is driven to transport the raw tire 1 at the first position A to the second position B. Further, in this case, in the second position B, as shown in FIG. 1, the axial center of the raw tire 1 coincides with the axial center of the piston rod 50a of the cylinder mechanism 50, and at the same time as the axial center of the lower opening / closing mechanism 10. Match. The movement of the holding frame body 30 is controlled by a limit switch or the like.

Then, as shown in FIG. 4C, the piston rod 50a in the retracted state is extended, the locking pawls 9 ... In the closed state are inserted into the raw tire 1, and as shown in FIG. The pawls 5 ... Are opened and locked to the lower bead portion 3. In this case, when the piston rod 50a is fully extended,
The locking claw 9 comes to a position corresponding to the lower bead portion 3, and in this state, the locking claw 9 ... Is opened and locked to the lower bead portion 3.

Next, with the upper bead portion 2 being locked by the locking claws 5 ... And the lower bead portion 3 being locked by the locking claws 9 ..., the piston rod 29a is retracted to set the locking claws 5 ... The distance L is increased and the dimension L between the upper and lower bead portions 2 and 3 is enlarged to maintain the state for a predetermined time (predetermined time), and the raw tire 1 is corrected to a predetermined regular shape. In this case, the pulling force is kept constant by a pressure reducing valve attached to the cylinder mechanism 29. Also,
Separate pressures are used for rising and falling. It should be noted that the predetermined distance differs depending on the size of the raw tire 1, and the distance L between the upper and lower bead portions 2 and 3 is normal, and the predetermined time is the raw tire modified to a predetermined regular shape. It means the time when 1 does not return to the original deformed state even if it becomes free.

Then, during the correction, the raw tire 1 is heated by the heating means 52 as necessary, and the rigidity of the sidewall portion or the like is lowered, so that the correction can be performed more easily. That is, hot air is blown out from the outlet 57 that is inclined and opened upward, and the inside of the green tire 1 is warmed, and the rigidity of the sidewall portion and the like is reduced. Then, if this state is maintained for a certain period of time, the raw tire 1 returns to a predetermined regular shape.

Next, the locking claws 5 ... Are closed and raised, and at the same time, the locking claws 9 ... are closed and lowered, and subsequently, the holding frame body 30 is moved to the first position A, and The corrected raw tire 1 is chucked by the chuck portion of the vertical loader, and the raw tire 1 is put into the mold of the vulcanizer. In addition, in order to close and raise the locking claws 5 ..., the vertical loader puts the raw tire 1 into the mold, and the empty loader rises again and goes out of the machine. This is done by a signal, and when it is used as a repair machine of this device, it is done by a push button signal of an operator.

If another raw tire 1 is placed at the first position A while the raw tire 1 is being corrected, the raw tire 1 can be sequentially corrected by repeating the above cycle. If the light receiving unit 62 receives the light from the projection unit 61 when the holding frame body 30 returns to the first position A, it means that the raw tire 1 is not placed at the first position A. The holding frame body 30 returns to the second position B again and moves to the first position A after a lapse of a certain time. It should be noted that when moving to the first position A, it is safe to sound the buzzer to let the operator.

It should be noted that the present invention is not limited to the above-described embodiment, and design changes can be freely made without departing from the scope of the present invention. In the embodiment, the heating means 52 is provided, but of course, the heating means 52 is provided. The heating means 52 may be an infrared heater or the like to heat the inside of the raw tire 1. Further, although the number of the locking claws 5 and 9 is six in the embodiment,
The number can be increased or decreased freely, and a cylinder mechanism is used as the drive mechanism for the opening / closing mechanisms 6 and 10 and the elevating means 7 and 11, but of course other drive means such as a combination mechanism of a motor and a screw can be used. You are free to use it.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

The raw tire 1 deformed from the predetermined regular shape is corrected to the predetermined regular shape, received, and then put into the vulcanizer in this state. It does not cause excessive deformation, and there is no concern about defective air remaining. Furthermore, the uniformity of the finished tire is improved without giving excessive deformation to the bead portions 2 and 3.

Further, if the raw tire 1 is heated during the correction, the correction can be assisted, the working time can be shortened, and the working efficiency can be improved.

Further, since the raw tire 1 is lifted and conveyed by the elevating means 7, the height dimension of the mounting table 4 can be made relatively small, which reduces the mounting height of the raw tire 1. , The placement work will be easier by hand.

Then, since the upper bead portion elevating means 7 is moved in the horizontal direction by the transport mechanism 8 to move the locking claws 5, ..., It can be used as a moving device of the raw tire 1, and
When checking the modified raw tire 1 with a vertical loader, these locking claws 5 and the like can escape and do not interfere.

If the locking claws 5 do not move in the horizontal direction, the placement position of the raw tire 1, the correction position of the raw tire 1, and the picked-up position of the raw tire 1 after correction may be the same. In this case, since it is extremely difficult to perform these operations and the locking claws 5, etc., it is necessary to set the above-mentioned placement position, correction position, and pick-up position separately. Therefore, the mounting table 4
Has a disadvantage that it requires a large space because the length of the device becomes large and the entire device becomes large. On the other hand, in the raw tire receiving device according to the present invention, the mounting table 4 may be provided with the two positions of the first position A and the second position B, so that the length of the mounting table 4 is not large. Moreover, the locking claws 5 ... Are not an obstacle during the placing and picking up of the raw tire 1.
