Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a loader for a tire vulcanizer attached to a tire vulcanizer of a type in which a beam attached with an upper die moves up and down and moves forward and backward.

[0002]

[Prior art]

 This type of tire vulcanizer loader includes four pairs of cam followers 4 vertically and horizontally fixed to a side plate 2 of a loader body 1 via an adjusting plate 3, as shown in FIGS. A beam (not shown) of the vulcanizer is engaged with a side rail 5 fixed to a beam that can be moved up and down and forward and backward, and the loader main body 1 is moved up and down and forward and backward together with the beam and the side rail 5 fixed thereto by the action of driving means (not shown) When the beam is at the retracted end, the center 5 of the grip portion 6 of the loader body 1 is adjusted so as to coincide with the center of the lower mold (not shown).

[0003]

[Problems to be solved by the device]

 It is important for tire quality to install the unvulcanized tire suspended by the loader concentrically on the lower mold, but in the above-mentioned conventional device, the oil sliding state of the beam driving means and the operating state of the brake are used. As the rear end stop position of the beam changes due to changes in the beam, the center of the gripping part 6 attached to the loader body 1 that moves integrally with the beam via the side rail also becomes off-center with the center of the lower mold and is frequently centered. There was a drawback that we had to readjust.

The present invention was developed to address such problems, and an object thereof is to facilitate centering of a loader body.

[0005]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 4 corresponding to an embodiment. The present invention uses the side rail 5 fixed to a beam that can be vertically moved and moved back and forth as a guide. In the tire vulcanizer in which the unvulcanized tire loading loader main body 1 is moved up and down along the side rails 5 via the cam followers 4 pressed against both sides of the rail 5, the cam followers 4 are mounted on one side of the rails 5. The pressed half 4b is attached to a swing lever 9 which is elastically contacted with one side of the rail 5 via a compression spring 10, and a guide plate 12 is provided on the loader main body 1 and the guide plate 12 is fixed to a base upright. It is characterized in that it is slidably engaged with the guide rod 15.

[0006]

[Action]

 According to the invention, the loader main body is held horizontally by the cam follower pressed by one side of the side rail by the compression spring by the above means, and the guide plate whose one end is fixed to the other loader main body is an upright guide rod fixed to the base. When they are engaged, the center of the gripper of the loader coincides with the center of the lower mold and the fixed position is selected.When the guide plate and the guide rod are engaged, the change of the stop position of the beam causes If there is an offset at the center of the lower mold, the upper or lower compression spring is pushed back to change the relative position between the beam, that is, the side rail and the loader body, and the off center is absorbed.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Reference numeral 1 denotes a loader body, and a side plate 2 of the loader body 1 is movably adjusted on one side of a side rail 5. A fixed cam follower 4a and a swingable cam follower 4b pressed against the other surface of the side rail 5 are provided. The swingable cam follower 4b swings on the side plate 2 via the bracket 7 and the pin 8. A shaft 11 having a compression spring 10 inserted therein is attached between the bracket 7 and the lever 9, which is attached to the tip of the lever 9 that is assembled as possible. Normally, the cam follower 4b is moved to the side by the repulsive force of the compression spring 10. The loader body 1 is held horizontally by being pressed against the rail 5.

On the other hand, the loader body 1 is provided with a guide plate 12 having one end fixed, a guide hole 13 is provided at the tip of the guide plate 12, and an upright guide rod 15 provided on a base 14 is inserted into the guide hole 13. The fixing position of the inner rod 15 is selected such that the center of the grip portion 6 of the loader coincides with the center of the lower mold when engaged. Thus, when the guide plate 12 and the guide rod 15 are not engaged with each other, the loader body 1 is maintained horizontal by the action of the compression spring 10 and is guided by the side rails 5 to move up and down. When there is an off center between the gripper 6 of the loader and the center of the lower mold due to the fluctuation of the stop position of the beam when the guide rod 15 and the guide rod 15 are engaged, the upper or lower compression spring 10 is pushed back and the beam, that is, the side rail 5. The relative position with respect to the loader body 1 changes, and the offset center is absorbed.

[0009]

[Effect of device]

 As described above, according to the present invention, half of the cam followers that are pressed against both sides of the side rail are attached to the swing lever that is elastically contacted with one side of the rail via the compression spring, so that half of the cam followers are pushed into the side rail position. On the other hand, the loader body can be displaced to some extent, and a guide plate is provided on the loader body, and the guide plate is slidably engaged with a fixed upright guide rod based on the guide plate. ) It is possible to adjust the movement amount change caused by the stop accuracy of the main motor brake by the centering method of the guide plate provided on the loader main body, and greatly reduce the number of times the main motor brake is opened and adjustment work is performed. It has the effect of being able to.
