Description

[Detailed description of the invention] (Field of industrial application) This invention is a post-inflator machine that performs inflation treatment on vulcanized tires, so that uniform cooling can be automatically achieved over the entire surface of the vulcanized tire. Regarding improvements made to.

(Prior art) A vulcanized tire that has been vulcanized and molded in a tire vulcanizer (tire press) is inflated in a post-inflator machine adjacent to the vulcanizer, that is, the inside of the tire is heated to prevent deformation. It is known that cooling is performed in a state where the air is filled with inflation air.

Such inflator machines are known, for example, as described in Japanese Patent Publication No. 47-36505 and Japanese Patent Application Laid-open No. 58-7338.

The inflator machine is rotatably provided with a tire holding means that holds the bead portion of the tire from above and below, and by rotating the tire, the tire is uniformly and uniformly cooled.

(Problems to be solved by the invention) In the conventional inflator machine, the rotation of the tire holding means was configured to rotate from the entire central mechanism, so the mass of the rotating part became large and a large driving force was required. I needed it.

In addition, since the entire tire holding means rotates,
A rotating joint had to be installed in the passage for sending cooling air inside the tire, making the air system complicated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tire support device for a post-inflator machine in which the mass of rotating parts is reduced and air piping is simplified.

(Means for Solving the Problems) In order to achieve the above object, the present invention takes the following measures. That is, the feature of the present invention is that the adjustment shaft part 2 is fixed in a vertical axis attitude to the lift beam 1 fixed to the machine frame, and the lower bearing cylinder 1 is attached to the adjustment shaft part 2.
A lower rim support 6 is rotatably fitted to the lower bearing tube 14 via a bearing 5, and a lower rim 7 is removably fixed to the lower rim support 6. and a mounting plate 3 above the lift beam 1.
7 is fixedly arranged, a locking shaft 16 is attached to the mounting plate 37 concentrically with the adjustment shaft section 2, and an upper bearing tube 9 is fitted onto the locking shaft 16 so as to be movable up and down. An upper rim support 11 is rotatably fitted to the outside via a bearing 10, an upper rim 12 is detachably fixed to the upper rim support 11, and a rotating member 13 is attached to at least one of the lower rim support 6 or the upper rim support 11. It is at the point where it is established.

(Function) According to the present invention, the lower bead of the tire is fitted to the lower rim, the upper bearing cylinder is lowered, and the upper bead of the tire is fitted to the upper rim to hold the tire. The tire is rotated by rotating the rim support using the rotating member. At this time, the central mechanisms such as the adjusting shaft, the lower bushing, and the upper bushing of the locking shaft do not rotate.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

An adjustment shaft section 2 is erected and fixed in a vertical axis attitude at the end of a lift beam 1 fixed to a machine frame. A locking hole 18 having a locking pawl 17 at its entrance is provided at the axial center of the top of the adjustment shaft portion 2 .

A lower bearing sleeve 4 is screwed onto the outer periphery of the adjustment shaft portion 2 via a screw fitting portion 3 so as to be freely movable in the axial direction.

A lower rim support 6 is rotatably fitted around the outer periphery of the lower bearing cylinder 4 via a bearing 5 .
The lower rim 7 is placed on the upper surface of this lower rim support 6.
is attached with a clamp 35 and a bolt 36 so as to be detachable and replaceable.

A center frame 8 is fixedly arranged above the lift beam 1, and a mounting plate 37 is fixed to the lower surface of the center frame 8. An L-shaped stopper plate 2 is attached to the bottom surface of this mounting plate 37.
0 is fixed with a bolt 38.

The adjustment shaft portion 2 is attached to the stopper plate 20.
A locking shaft 16 concentric with is rotatably held.

The locking claw 1 is attached to the lower end of the locking shaft 16.

is provided. This locking head 15 can be inserted into and removed from the locking hole 18 . That is, a locking groove is provided on the entrance side of the locking hole 18, which is out of phase with the locking pawl 17 and allows the locking pawl 14 of the locking head 15 to freely pass through. is rotated to lock the locking pawl 14 to the locking pawl 17 as shown, and is rotated in the opposite direction to release the locking pawl 17.

An upper bearing sleeve 9 is fitted onto the locking shaft 16 so as to be vertically movable.

A cylinder 19 is installed on the mounting plate 37, and a piston rod 19a of the cylinder 19 is connected to one side of the upper bearing sleeve 9. As the cylinder 19 expands and contracts, the upper bearing tube 9 moves up and down.
Its upper limit is the position where it contacts the stopper plate 20.

An upper rim support 11 is rotatably fitted around the outer periphery of the upper bearing tube 9 via a bearing 10 . An upper rim 12 is detachably attached to this upper rim support 11.

A rotating member 13 formed by a spur gear is fixed to the upper end of the outer periphery of the upper rim support 11 with bolts 39 . This rotating member 13 can be freely selected from other than a spur gear, such as a pulley transmitted by a belt, a sprocket transmitted by a chain, etc. In the case of a spur gear, it can be freely driven by a motor with a pinion gear meshed with it. Also, this rotating structure can be provided on the lower rim support 6 side, but only one of them is sufficient.

According to the embodiment, as shown in FIG. 1, a bearing 5 is attached to a bearing sleeve 4 which is adjustable via a screw fitting part 3 to an adjustment shaft part 2 which is provided upright at the end of a lift beam. A lower rim support 6 is rotatably attached to the lower rim support 6, and a lower rim 7 is fixed to the support 6, and an upper rim support 6 is attached via a bearing 10 to a bearing tube 9 which is movably held in the center frame 8 via a cylinder 19. A rim support 11 is rotatably attached, an upper rim 12 is fixed to the support 11, and in the illustrated example, a rotating member 13 such as a spur gear is attached to the support 11 to enable active rotation. A locking shaft 16 having a locking head 15 at the lower end with a locking pawl 14 at the center thereof is rotatably inserted through the stopper plate 20, and a locking pawl 17 is provided at the upper end of the adjustment shaft 2. A locking hole 18 with a
By providing this, the vulcanized tire can be held and rotated in the following manner.
That is, when holding a vulcanized tire, the tire is held between the upper and lower rims 12 and 7, and the locking shaft 16
This can be done by rotating the locking head 15, locking the locking pawls 14 and 17, filling the inflation air, and then rotating the rotating member 13 by an appropriate drive means. The upper rim support 11 integrated with the upper rim support 11 rotates. Therefore, the upper rim 12 also rotates, and since inflation air exists as internal pressure in the tire held integrally between the upper and lower rims 12 and 7, the tire, lower rim 7, and lower rim support 6 also rotate. Since the tire is constantly rotated and cooled during the inflation process, uniform and homogeneous cooling can be obtained without uneven cooling. When cooling for the required time is completed, the rotating member 13 is stopped.

(Effects of the invention) According to the invention, the upper and lower rim supports and the upper and lower rims rotate, and their rotating mass is smaller than that of the conventional one, so the rotational drive power can be reduced.

Furthermore, since the center mechanisms of the adjusting shaft and the locking shaft do not rotate, the vertical alignment can be highly accurate. Furthermore, since the air passage can be provided in the non-rotating portion, a conventional rotary joint is not required.
