Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tire take-out device for a tire vulcanizer.

(Prior art) A vulcanized tire cured with a tire vulcanizer is taken out from the upper mold of the tire vulcanizer by a tire take-out device and conveyed to a post-cure inflator (hereinafter referred to as PCI). Post-processing is performed, and a tire removing device used in this case is disclosed in Japanese Patent Application Laid-Open No. 61-61812.

This conventional tire take-out device connects a tire vulcanizer with a rotary shaft that can freely rotate around a vertical axis and move up and down in the axial direction.
C. At the same time, the rotating shaft is attached to the main body side of the tire vulcanizer, and the rotating arm 1, which has a chuck claw that can be freely expanded and contracted at the tip, is fixed to the rotating shaft.
By combining the vertical movement of the swivel arm and the swivel movement of the swivel arm around the rotation axis, the vulcanized tire on the lower mold of the tire vulcanizer is directly gripped and taken out by the chuck jaws, and then the lower rim of the PCI is removed. I am trying to transport it to the top.

(Problems to be Solved by the Invention) Conventional tire take-out devices require lifting and lowering operations to move the rotating shaft up and down, in addition to the swinging action of rotating the swinging arm. The structure becomes very complicated, and it is difficult to maintain stopping accuracy at the center position of the tire vulcanizer and PCI.

Furthermore, since the rotating shaft that supports the swing arm is located on the main body side of the tire vulcanizer, it is difficult to accurately adjust and maintain the accuracy of the PCI center position. Moreover, by directly gripping the upper bead of the vulcanized tire on the lower mold of the tire vulcanizer with the chafing claw and lifting it up, the vulcanized tire is peeled off from the lower mold. This can easily cause deformation of the parts. Furthermore, since the chuck jaws grip the upper bead of the vulcanized tire, the amount of elevation of the chuck jaws must be set according to the height position of the upper bead. Therefore, if the tire size changes, You need to adjust accordingly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tire take-out device for a tire vulcanizer that can solve all of the conventional drawbacks.

Each chuck claw 70 is provided with a limit switch 86 that detects gripping of the vulcanized tire 3 via a sensing plate 85. The sensing plate 85 is disposed in an elongated hole 87 formed vertically in the center of the chuck claw 70, and is urged outwardly by a guide mechanism 88 and a spring mechanism 89. There are two switch 86 on each chuck jaw 70, and they are attached to the inside of the chuck jaw 70 via a bracket 90 so as to be linked to the movement of the sensing plate 85. At the center of the chasok board 69, there is a shaft 9 projecting downward.
A stopper 92 is provided via l.

Next, the operation will be explained with reference to process charts showing the order of operation in FIGS. 14 to 22.

During vulcanization by the tire vulcanizer 1, the swing arm 38 is held at a standby position B between the tire vulcanizer 1 and the PCI 2, and the pair of push-up arms 21 of the push-up device 19 are moved outward. Keep it spread out.

When the vulcanization is completed, the upper mold 5 is raised as shown in FIG. 14, and the central mechanism 9 is also raised to peel the vulcanized tire 3 upward from the lower mold 7.

Next, the upper ring 10 of the central mechanism 9 is raised and the lower ring 11 is lowered to remove the bladder 12 from the vulcanized tire 3 inward. Furthermore, when the push-up cylinder 29 of the push-up device 19 is slightly extended, the bottle 31 rises relatively within the spiral groove 27 until the rod end 32 hits the adjustment bolt 33, so that the spiral groove 27 and pin 31 Due to this action, the guide shaft 22 rotates inward about the axis, and the pair of push-up arms 2l swing inward together with the guide shaft 22 to enter the lower side of the vulcanized tire 3. On the other hand, when the swing cylinder 61 or 62 is extended, the Geneva arm 55 or 56 swings, so the cam follower 53 or 54 slides along the elongated hole 49 or 50, and the swing arm 38 moves around the vertical axis 37. Turn counterclockwise. Therefore, in this way, the chucking device 39 at the tip of the swing arm 38 is positioned at the chucking position A approximately above the center of the vulcanized tire 3.

This is the state shown in FIG.

When the chucking device 39 is located at the approximate center position of the vulcanized tire 3, that is, the chucking position A, the push-up arm 21 is further raised as shown in FIG. Push up chuck device 3 from below
The chuck claw 70 of No. 9 is fitted onto the outside.

In this case, if the push-up cylinder 29;
Since the push-up arms 21 are pushed up together, the vulcanized tire 3 can be pushed up while being supported from below by the -U push-up arms 21. When gripping with the chuck device 39, by extending the expansion/contraction cylinder 71, the three chuck claws 70 expand outward in the radial direction, and the vulcanized tire 3
grip the upper bead portion 3a from the inside. Therefore, if a structure is adopted in which the tire is pushed up with one push-up device and then gripped with the chuck device 39, even when the tire size is changed,
It is only necessary to change the push-up height of the push-up device 19, which is very convenient. When the expansion/contraction cylinder 71 is extended when gripping the vulcanized tire 3, the rotation ring 72 rotates counterclockwise around the support ring 73, so that the ring 78
pushes the slider 82 outward through the pin 83. As a result, the sliding body 82 moves outward along the guide bar 75, and the chuck claws 70 expand. Then, the limit switch 86 works, and the vulcanized tire 3 is removed by the chuck device 39.
When the grip is detected, the push-up cylinder 29 is contracted and the push-up arm 21 is lowered.

At this time, if the push-up arm 29 is lowered to the lowest position,
Due to the action of the pin 31 and the spiral groove 27, it swings outward and returns to the open state.

On the other hand, the swing cylinders 61 and 62 are moved backward to swing the swing arm 83 toward the PCI 2 around the vertical axis 37, and align the center of the chuck device 39 with the center of the lower rim 15 of the PCI 2. . Then, as shown in FIG. 17, the lower rim 15 is raised by contracting the lifting cylinder 17, and the lower rim 15 is fitted into the lower bead portion 3b of the vulcanized tire 3 from below.

Next, the contraction cylinder 71 is operated to contract, and the chuck device 3
When the chuck claws 70 of 9 are contracted inward, the vulcanized tire 3 is placed on the lower rim 15, so by extending the lifting cylinder 17, the lower rim 5 is moved while receiving the vulcanized tire 3. Then, as shown in FIG. 18, the vulcanized tire 3 is pulled out from the chuck jaws 70 downward.

Then, by extending the swing cylinder 61 or 62 and swinging the swing arm 38 along the vertical axis 37,
After returning the chasok device 39 from the Pct 2 side to the standby position A, the lifting cylinder 16. After the vulcanized tire 3 is held between the upper rim 14 and the lower rim 15 and completely locked, the vulcanized tire 3 is subjected to post-processing by the PCI 2.

When the processing by the PCT 2 is completed, the lifting cylinder 17 is extended to lower the lower rim i5 to the lowest position, the vulcanized tire 3 is placed on the discharge conveyor 93, and then the tilting cylinder 9
4 and tilts the discharge conveyor 93, the tires 3 on this discharge conveyor 93 are discharged. This is shown in FIGS. 21 and 22.

(Effects of the Invention) In the present invention, a swing arm 38 that can freely swing around a vertical axis 37 is disposed between the tire vulcanizer 4ffll and the post-cure inflator 2, and a chuck claw 70 is provided at the tip of the swing arm 38 to expand and contract. A freely movable chuck device 39 is provided, and the chuck claws 70 of this chuck device 39 grip the vulcanized tire 3 of the tire vulcanizer, and the swing arm 38 is rotated around the vertical axis 37 to perform post-curing. In a tire take-out device of a tire vulcanizer that conveys flakes 2 onto a lower rim 15, a push-up device 19 pushes up a vulcanized tire 3 on the tire vulcanizer 1 side to a chucking position A of a chuck device 39. , and a vertical shaft 37 that supports a rotating arm 37 is provided on the post-cure inflator 2 side. Therefore, according to the present invention having such a configuration, the following remarkable effects are achieved.

i) When the vulcanized tire 3 is taken out and transported, the rotating arm 38
Since it is only necessary to rotate about the vertical axis 37N, the structure of the supporting portion is simple, and it is easy to maintain a predetermined stopping accuracy.

ii) Since the vulcanized tire 3 on the tire vulcanizer L side is pushed up to the chucking position A by the push-up device 19, the central accuracy of the tire vulcanizer 1 side of the chuck device 39 is not required to be very high; , the vertical shaft 37 supporting the pivot arm 38 is connected to the PCI
Since it is provided on the PCI 2 side, sufficient centering accuracy on the PCI 2 side can be ensured, and it is easy to adjust and maintain the accuracy.

iii) Since the chuck device 39 grips the vulcanized tire 3 on the push-up device 19, deformation of the tire bead portion is unlikely to occur.

iv) Even when the tire sizes are different, the chuck device 3
