Abstract

PURPOSE:To make a height of a tire grasping mechanism adjustable by the rotation of a screw, by supporting the lower end of a vertical shaft supporting a boom in a rotatable manner on a base stand through the screw. CONSTITUTION:An end 5a of a boom 5 is formed into a hollow cylindrical shape and two ball bearings 6 are provided in the boom 5 so that the outer surfaces thereof are aligned with the inner surface of the boom and the inner surfaces thereof are aligned with the outer surface of a shaft 7. A screw 7d is provided to the under side of the lower end part 7c of the shaft 7 to be engaged with the female screw provided to a base stand 4 and a tire grasping mechanism is provided to the lower end of the boom 5. Therefore, when a spanner is adapted to an end square pillar part 7e at the end of the shaft 7 and revolved, the boom 5 can be raised and lowered by the action of the screw 7d. In a loader having such a type that the left and right sides of a tire vulcanizing machine are simultaneously raised and lowered, the left and right heights thereof can be altered and a raw tire different in left-hand and right-hand heights can be grasped.

Description

[Detailed description of the invention] & Detailed description of the invention Industrial applications The present invention relates to a loader for a tire vulcanizer.

Conventional technology A tire gripping mechanism equipped with a shoe that can be expanded and contracted in the radial direction is suspended and supported on the underside of a boom that rotates around a vertical axis.
By rotating the zoom, the green tire gripped by the tire gripping mechanism is transported from the supply device to the tire vulcanizer.

Problems to be Solved by the Invention In the prior art as described above, the height of the boom is constant;
This cannot be done when the heights of the raw tires to be supplied are different, such as when two lines of supply devices are installed.

Means for solving the problem The lower end of the vertical shaft that rotatably supports the boom is supported on a pedestal via a screw, and by turning the screw, the height of the boom can be adjusted, and therefore the tire gripping mechanism attached to the boom can be adjusted. Adjust the height.

By turning the screw on the working boom support shaft, the boom height can be adjusted and green tires with different heights can be gripped.

Embodiment In FIGS. 1 to 4, 1 is a frame, 2 is a rail, 3 is a slider, 4 is a pedestal, and 5-piece boom.

5a is the bearing case at the base of the poom 5, 5b is the disc 5
The cylinder to which c is attached, 5 (1 is the groove in the disc 5c.

6 is a ball bearing, 7 is a shaft, 7a is a 7 flange of the shaft 7, 7t+ is the upper end of the shaft 7, and 7c is the lower end of the shaft 7.

7d is the screw s below the lower end 7c; 7e is the lower end prismatic part;
8 is a nut, 9 is a spacer, and 10 is a fluid pressure cylinder.

11 is a shoe, 12 is a disk, 13 is a link, 14 is a retaining ring, 15 is a lever, 16 is a pin, and 17 is a fluid pressure cylinder.

17a is the clevis, 18 is the retaining ring, 19 is the bolt, 20
21 is a nut, 22 is a pin, 23 is a hydraulic cylinder, 23a is a clevis, and 24 is a pin.

4 that can slide on two rails 2 fixed to the frame l
The sliders 3 are assembled together, and the sliders 3 are fixed to a frame 4 using bolts. One end 5a of the pool 5 has a hollow cylindrical shape and has two ball bearings 6 inside it.
Align the outer surfaces of the

The inner surface of the ball earring 6 is in static fit with the outer surface of the shaft 7. The shaft 7 has a flange 7a and a nut 8 attached to the screw provided at the upper end.
The shaft 9 and the ball bearing 6''Ik are fixed using a screwdriver.The upper end 7°C and the lower end i%7c of the shaft 7 are respectively engaged with holes provided in the pedestal 4. Below the lower end 7C. The side is provided with a screw 7d which engages with a female screw provided on the pedestal 4°.The lower side of the screw 7d is a prismatic portion 7e.The hydraulic cylinder 10 is attached to the pedestal 4 with its intermediate trunnion 10a. The tip 1013 of the lot 1 is cylindrical and is fitted loosely with the hole provided in the pool 5. A plurality of cylinders 5b forming a body with the pool 5 are provided at one end of the pool 5. The plate 5C is one body, and the 0 disk plate 5C has a plurality of grooves 5.
d is provided, and matching sheets 5--11 are fitted together in the shape shown in FIG. The hole at one end of the link 13 is loosely engaged with the disc 12 and the one-piece pin 12a, and the shoe 11 and the one-piece pin ll& are loosely engaged with the hole at the other end, and set with a retaining ring 14. The center part of the disc 12 is cylindrical and fits in a hole provided in the disc 5C, and its upper end is fixed to the lever 15 with a pin 16. The fluid pressure cylinder 17 is loosely engaged with a pin 5d that is integral with the pool 5 using a retaining ring 18. The rod end clevis 17L of the fluid pressure cylinder 17 is attached to a groove provided in the lever 15 using a bolt 19 with a spacer and a nut 21. The outer surface of the spacer 20 and the inner surface of the clevis 17a play and rotate relative to each other. A hydraulic cylinder 2 is connected to the lug 4a, which is integrated with the pedestal 4, by means of a pin η.
The rod end clevis 23a of No. 3 is pivotally connected. The upper side of the fluid pressure cylinder 23 is connected to the lug 1 of the frame 1 using a pin 24.
It fits loosely in the hole provided in a.

Therefore, if the lower end of the shaft 7 is rotated using a snare or the like, the pool 5 can be raised or lowered by the action of the screw 7d.

Loosen the nut 21 and insert the bolt 19 into the groove 15 provided in the lever 15. When the nut 21 is tightened at the predetermined position of the disc 12. The opening limit position of the shoe 11 is determined by the action of the link 13. Thereafter, when the fluid pressure cylinder 17 is shortened using a pressure medium, the shoe 11 is operated in the closing direction, and the eye is closed at the end of the stroke of the fluid pressure cylinder 17.

Effects of the Invention In a loader that simultaneously lifts and lowers the left and right sides of a tire vulcanizer, it is possible to change the height of the left and right sides, and it is possible to grip green tires with different heights on the left and right sides.
