A device for unloading tires from a vulcanization press j is known, which comprises vertical spindles mounted on frames, on which hubs with grippers are mounted and connected with the latter: by means of t and moving relative to their carriage, and driving vertical spindles.

.3 of such a device, the movement of the carriages relative to the hub with grippers is carried out by independent drives, in which power rams are used, which considerably complicates the design of the device.

The purpose of the invention is to simplify the design.

For this, in the proposed device, the movable cages are spring-loaded relative to the hubs of the claws and provided with locking fingers, which are permanently pressed against the hinge-mounted latch hinges on the hubs of the grips, which interact with the locking fingers of the movable carriages when the grips are diluted.

To release the grippers, the latches are provided with scraper rollers that interact with fixed stops mounted on the frame.

; Fig, 1 shows the proposed device; in fig. 2 is a view along arrow A in FIG. one; Fig, 3, the proposed device at the time of fixation of the grips when unloading pokryshki from the upper half-form; in fig. 4 - the same, at the time of raskfikadii captures; in fig. 5 is a section along BB in FIG. four.

The device for unloading tires is made in the form of vertical spindles 1 installed in guide sleeves 2 of frame 3. On each spindle there is mounted a hub 4 with grips 5 and a movable relative

Their carriage 6 is associated with the grippers by means of r G 7.

The springs 8 serve to hold the carriages in the off position. The movable carriages 6 are provided with locking1 "And fingers 9, to which the latches 11, which are hinged by means of axles 12 on the hubs 4 of the grips 5, are permanently pressed by the pinskins 10. and are equipped with copy rollers 13, which interact with fixed stops 14. mounted on frame 3. Hubs 4 are fixed to the hubs 4 of the grippers. On the upper end of spindles 1 are spring-loaded stops 16. The end of spindles is designed as a toothed rack. The vertical drive of the spindles consists of a hydraulic cylinder 17, on the rod of which a rack 18 interacting with the gear gear 19, and a drive shaft 20 with gear wheels 21 interacting with the gears arranged on the spindles.

On the frame 3, two shoulders levers 22 and roller tables 23 are hinged.

The device works as follows.

Pressure is supplied to the piston chamber of the hydraulic cylinder 17. At the same time, through the gear rail 18 and the gear gear 19, the drive shaft 20 is rotated with the gear wheels 21. The spindles 1 move upward until the movable carriages 6 touch the gear housings 24 | of the detachable parts mounted in the upper mold half of the vulcanization press. At this moment, the ends of the grippers 5 are inside the snouched pokryshkas 26 (shown in dotted lines in FIG. 3), and the tires are held apart by the vanes 27 of the mechanisms 24, With further movement of the spindles 1 upwards the carriage 6, compressing the springs 8, different, d t The grippers 3, which press the lower sides of the pockets of the ek 26 to the bead rings 15. The stops 16, pressing the levers 28 of the mechanisms 24, rotate them, and the blades 27 are reduced, releasing the upper boards. tires -

Then, pressure is applied to the supra-pneumatic cavity of the hydraulic cylinder 17, the spindles 1 are lowered. In this case, under the action of the springs 8, the carriages 6 move up along the spindle m, and the fingers 9 of the carriages go into the locking grooves of the latches 11, fixing the grippers. 5 in the divorced position. When lowering the spindles 1, the grippers 5. pull out the vulcanized pokryshki 26 from the upper half-form. The pockets are now held by the claws 5 on the bead rings 15.

Upon further lowering of the spindles 1, the cam rollers 13 of the latches 11 overlap the stops 14. Having overcome the resistance of the springs 10, the stops 14 press the latches 11 and release the fingers 9 of the movable carriages 6 from the grooves a. The carriages 6 are returned to their initial position by the springs 8, the arch is the grippers 5 and. freeing the lower sides of the pockets; At this moment, the side rings 15 press on the two shoulders levers 22, turning them, and the levers 22 turn the live rolls 23,

which remove the tires from the side rings 15.

Upon reaching the required angle of inclination of the roller tables of the tire, under the influence of their own weight, the chutes are brought from them to the selection conveyor or to the cooling unit.

The process then repeats. 10 The proposed unloading device can be used in automatic lines for forming and vulcanizing tires.
