Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tire manufacturing industry especially a kind of automatic ring collecting mechanism of triangular rubber bonding machine. BACKGROUND

[0002] The bead of a tire is the portion of the tire that fits over the wheel rim. The bead can withstand the stretching force caused by the internal pressure of the tire, and can also overcome the lateral force action on the tire during cornering, so that the cover does not come off the rim, and therefore the bead must have a very high pressure-bearing capacity, and its structure should be tight and strong, not easy to deform.

[0003] The bead usually includes a steel wire ring and a triangular rubber bonded to the steel wire ring. Currently, the triangular rubber bonding of the bead is usually completed on a semi-automatic or fully automatic production line. A Chinese invention patent (patent number CN201610078629.7, authorized publication number CN105619858B) discloses a full-automatic horizontal triangular rubber bonding machine. A cold feeding extruder 1 extrudes the triangular rubber, which is then delivered to a triangular rubber traction cooling device 3 through a receiving conveyor and a stretching and contracting device 2, cooled, and then collected on a constant-tension storage device 4. Finally, the bonding of the triangular rubber and the steel wire ring is completed on an automatic bonding device 5. On both sides of the automatic bonding device 6, there are a steel wire ring automatic ring feeding device 5 and an automatic ring collecting and arranging device 7. The steel wire ring automatic ring feeding device 5 automatically delivers the steel wire ring to the automatic bonding device 6 to complete the bonding of the steel wire ring and the triangular rubber. Finally, the automatic ring collecting and arranging device 7 realizes automatic ring collecting and arranging. The automatic ring collecting and arranging device 7 includes a triangular rubber collecting mechanism 7.1 and an automatic ring collecting mechanism 7.2. The ring collecting arm 7.2.2 of the automatic ring collecting mechanism 7.2 drives the bonded triangular rubber to the up-and-down movable ring collecting platform 7.2.4 of the automatic ring collecting device 7.2. During the descending process of the ring collecting platform 7.2.4, the triangular rubber is hooked by the transmission arm 7.1.4 of the triangular rubber collecting mechanism 7.1 and vertically hung on the transmission arm 7.1.4, so as to realize the automatic collection and arrangement of the triangular rubber on the automatic bonding device 6 to the triangular rubber collecting mechanism 7.1 by the automatic ring collecting mechanism 7.2. However, the automatic ring collecting mechanism 7.2 has the following problems: since the triangular rubber is vertically hung on the transmission arm 7.1.4, it will cause the triangular rubber to be uneven, and still needs to be manually taken off from the transmission arm 7.1.4, which cannot realize complete automation. SUMMARY

[0004] The applicant provides the automatic bead collecting mechanism with reasonable structure, which cancels the bead collecting mechanism, sets the horizontal conveyor on one side of the first platform, collects the beads through the AGV trolley after keeping the horizontal output of the beads, does not need manual collection, and realizes complete automation.

[0005] The technical scheme adopted by the utility model and the technical effects realized are as follows:

[0006] The automatic bead collecting mechanism of the triangular rubber attaching machine has the upper layer of the rack, the material moving device vertically lifted and horizontally slidably arranged above the second platform, and the bead collecting arm horizontally slidably arranged on one side of the second platform.

[0007] The bead collecting arm places one bead of the automatic attaching device on the first platform, the material moving device transports one piece of the spacer from the second platform to the first platform, the gravity of the horizontally stacked beads and the spacer can flatten the beads and the spacer, the first platform is lowered to the bottom of the stroke, the beads and the spacer are horizontally transported by the belt of the conveyor, and the AGV trolley is used to collect the beads without manual collection, so that complete automation is realized.

[0008] As a further improvement of the above technical scheme:

[0009] The first platform has the belt, and the belt of the first platform and the conveyor is driven to move in the same direction by the motor. The first platform and the conveyor horizontally transport the beads and the spacer, and ensure the stable transportation of the beads and the spacer.

[0010] The rack is provided with the pulley and the synchronous belt, the screw is vertically arranged between the upper layer and the lower layer of the rack, one end of the screw is connected with the pulley, the first platform is slidably arranged on the screw, the motor drives the pulley to rotate, the pulley and the synchronous belt jointly drive the screw to rotate, and the screw drives the first platform to vertically lift.

[0011] When the first platform is at the highest point, the upper surface of the first platform is lower than the second platform, and when the first platform is at the lowest point, the upper surface of the first platform is flush with the conveyor.

[0012] The first platform is raised to its highest point of travel. The retracting arm and the material transfer device work together to make the triangular rubber and spacers stacked horizontally and at intervals on the first platform. Each time a triangular rubber or spacer is placed, the pulley, timing belt and lead screw control the first platform to descend a certain height. When the predetermined number is placed on the first platform, the first platform descends to the bottom of its travel, and the belt of the first platform can be started.

[0013] A counterweight is installed on the side of the lead screw away from the first platform. The counterweight helps the first platform maintain overall balance when lifting under load, and reduces the load on the motor when it stops, thus extending the motor's lifespan.
