Tire unloading device for tire building machine

Abstract

The invention provides a tire unloading device for a tire building machine, which is used for forwards or backwards unloading green tires to be built. The tire unloading device comprises a horizontal shifting support frame, an automatic tire unloading mechanism arranged on one side of the support frame and a control assembly, wherein the automatic tire unloading mechanism comprises a depressing part arranged at the upper part of the support frame and a holding part arranged at the lower part of the support frame, and at least one of the depressing part and the holding part can shift up and down to grip or loosen a green tire to be built; the holding part comprises a bearing plate with up and down rotatable front and back ends, at least two holding paws pivoted with the front and back ends of the bearing plate, and a tire unloading driving assembly for driving the bearing plate to rotate; and when the automatic tire unloading mechanism is in a tire unloading state, the tire unloading driving assembly drives the bearing plate to rotate and causes the bearing plate to tilt forwards or backwards, thereby guiding the green tire to be built to be unloaded forwards or backwards.

Description

technical field [0001] The invention belongs to the technical field of rubber tire building machinery, and in particular relates to a tire unloading device for a tire building machine capable of unloading tires forward or backward. Background technique [0002] In the tire manufacturing process, firstly, the semi-finished rubber material and steel ring are assembled to form a green tire by using a tire building machine. Here, the green tire refers to the green tire that has not been vulcanized. [0003] In the existing tire building machine, after the production of raw tires is completed, the embryos need to be manually unloaded and inspected. After passing the test, they are transported to the next process. In this way, the labor intensity of the workers is high, and manual handling can easily cause collisions with the raw tires. It is difficult to guarantee the quality of raw tires, and it is difficult to cooperate with the production line, which is not conducive to the lo...

AI Technical Summary

Problems solved by technology

[0003] In the existing tire building machine, after the production of raw tires is completed, the embryos need to be manually unloaded and inspected, and the embryos are transported to the next process after passing the test. This method requires a lot of work intensity for workers, and manual handling can easily cause collisions with the raw tires. It is difficult to guarantee the quality of raw tires, and it is difficult to cooperate with the production line, which is not conducive to the low degree of automation of tire automation and low production efficiency; another existing tire building machine automatically unloads tires through an automatic tire unloading device, and directly For the next process of transporting to one side, due to the high transmission speed of the automated conveyor line, workers do not have enough time to overhaul the raw tires, and must stop or reduce the speed of the production line for overhaul, which is difficult to achieve without reducing production efficiency. Guarantee the quality of raw tires, reduce the molding time of raw tires, increase production costs, and the work intensity of workers is also strong
