Description
Technical Field
The present invention relates to the field of manufacturing equipment for high-end silent tires, and in particular to a method, apparatus and production line for manufacturing sound inhibitor units having an adhesive layer.
Background
With popularization and popularization of new energy vehicles such as electric vehicles in China, the functional requirements of the new energy vehicles on low-noise tires cannot be met due to the fact that the tire noise of the traditional tires is large.
In the prior art, a belt-shaped sound absorbing material is adhered to a region corresponding to a tread portion of the inner surface of a tire, but the sound absorbing material and an adhesive layer thereof generate heat in association with running of the pneumatic tire. Accordingly, there is proposed a tire in which a sound absorbing material is bonded to an inner wall of the tire in a band-like manner by sections, and an air stirring portion is formed to reduce the temperature, which is a problem that the sound absorbing material is easily peeled off from an inner surface of the tire due to softening or deterioration of an adhesive layer for fixing the sound absorbing material, and for this purpose, patent application 201480062532.6 is filed.
In addition, the double endurance tire stock company presents a method and apparatus for manufacturing tires having segmented noise reduction elements, see 201580057269.6 for details. The technology is to provide a continuous film having a layer of adhesive material supported on a first conveyor belt (10), transfer and adhere the adhesive material to a noise reduction element (100) by a pressing member (60), then transfer to a second conveyor belt (20) and take the noise reduction element out of the second conveyor belt (20) by a first gripping member (83) and a first suction device (85) on a first robot arm (80) and attach it to the inner wall of a tire. Since the adhesive material is transferred to the surface of the noise-reducing element on the side of the conveyor belt, the first gripping member presses the noise-reducing element and then gradually grips the noise-reducing element from its head end portion 100' when the flow is transferred onto the second conveyor belt (see fig. 5 of the patent specification and the related specification), the method and apparatus disclosed in the patent have the following disadvantages due to the certain adhesion between the pressed noise-reducing element and the second conveyor belt: 1. the noise reducing element is difficult to grasp from the second conveyor belt quickly, and the noise reducing element can be torn off from the second conveyor belt from one side only gradually; 2. the first suction device (85) needs to continuously output suction force, and the electric energy waste is large.
