Automatic tire blank conveying manipulator tire contact device

Abstract

The invention relates to the field of tire production and conveying, in particular to an automatic tire blank conveying manipulator tire contact device. The automatic tire blank conveying manipulatortire contact device comprises a support, a tension spring and a tension spring tire contact rod. The tension spring tire contact rod is an L-shaped rod formed by a long arm and a short arm, and the short arm of the tension spring tire contact rod is fixedly connected with the tension spring and colinear with the short arm. One end of the support is rotatably connected with the tension spring tirecontact rod, and a proximity switch hole is further formed in the support. The tire contact device has the advantages that the tire contact device is installed on the inner side of a mechanical gripper, so that a tire blank cannot be scratched, and the situation that the tire contact device is not concentric with a manipulator, and consequently effective detection cannot be achieved cannot be caused; and the tire contact device is installed on the inner side of the mechanical gripper, the tire blank cannot be damaged, and meanwhile the problem that a mechanism gets stuck and cannot perform detection due to dead corners when being in contact with tires of some specifications is solved; and the problem that a seam allowance and a tire side wall are scratched due to the sticky problem of thetire blank and the too large sliding resistance of the tire contact plate is also solved.

Description

technical field [0001] The invention relates to the field of tire production and transportation, in particular to a tire contactor device for an automatic tire embryo conveying manipulator. Background technique [0002] The tire touch device is a component of traditional Chinese medicine that the manipulator Jia Ce grabs the tire to realize automatic operation. The existing automatic embryo conveying manipulator adopts the structure of rotating upward around the fulcrum or spring return. Sliding up produces a lot of frictional resistance, resulting in scratches on the rim and the sidewall, and in special cases, it will be stuck and squeeze the sidewall and rim. [0003] The patent "Tire Sizing and Vulcanizing Machine Tire Toucher", (publication number CN104015282A), adopts a vertical roller structure, and the tire touch position uses rollers to realize the expansion and contraction of the manipulator without scratching the tire, but the embryonic structure is that the bezel ...

Problems solved by technology

[0002] The tire touch device is a component of traditional Chinese medicine that the manipulator Jia Ce grabs the tire to realize automatic operation. The existing automatic embryo conveying manipulator adopts the structure of rotating upward around the fulcrum or spring return. Sliding up produces a lot of frictional resistance, resulting in scratches on the spigot and the sidewall, and in special cases, it will be stuck and squeeze the sidewall and spigot

[0003] The patent "Tire Sizing and Vulcanizing Machine Tire Toucher", (publication number CN104015282A), adopts a vertical roller structure, and the tire touch position uses rollers to realize the expansion and contraction of the manipulator without scratching the tire, but the embryonic structure is that the bezel is much higher than the sidewall , there will be a slit stuck between the two rollers or beyond the detection range, which will cause the embryo to fail to roll and damage the embryo, and in severe cases, the embryo will be scrapped

[0004] The patent "Tire Sizing and Vulcanizing Machine Manipulator Tire Toucher Device" (publication number CN104385503A) adopts a connecting rod structure. Although it solves the problem of flexibility and stagnation, the tire embryo is a rubber that has not been Liu Hua, which has a certain viscosity and is flat. When the manipulator expands and contracts, the straight contact plate cannot slide due to too much resistance, causing damage to the embryo. There is also the fact that the embryo and the manipulator are not concentric, so that the damaged embryo cannot be effectively detected. At the same time, due to too many parts and welding and On the manipulator, there is a risk of falling into the embryo and it cannot adapt to embryos with many specifications
