Description
Technical Field
The present invention relates to the field of manufacturing equipment for high-end silent tires, and more particularly to a method, apparatus and manufacturing line for manufacturing a sound suppressing member unit having an adhesive layer.
Background
Along with the popularization and the promotion 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.
Conventionally, a band-shaped sound absorbing material is bonded to a region corresponding to a tread portion of an inner surface of a tire, but the sound absorbing material and its bonding layer generate heat as a pneumatic tire travels. Therefore, there is a problem that an adhesive layer for fixing the sound absorbing material is softened or deteriorated and the sound absorbing material is easily peeled off from the inner surface of the tire, and for this reason, a tire in which a band-shaped sound absorbing material is adhered to the inner wall of the tire in a stepwise manner and the temperature is lowered by forming an air stirring portion is proposed by shozuku corporation, and the detailed content of which is disclosed in patent application No. 201480062532.6.
Additionally, the double endurance tire company has proposed a method and apparatus for manufacturing tires having segmented noise reducing elements, the details of which are disclosed in the 201580057269.6 patent application. The technique of this patent is to provide a continuous film with a supporting layer of adhesive material on a first conveyor belt (10) and transfer and adhere the adhesive material to the noise reducing element (100) by means of a pressing member (60) and then to a second conveyor belt (20) and to take the noise reducing element from the second conveyor belt (20) and apply it to the inner wall of the tyre by means of a first gripping member (83) on a first robot arm (80) and a first suction device (85). Since the viscous material is transferred to the surface of the noise reducing element on the side close to the conveyor belt, when the viscous material is transferred to the second conveyor belt, the first gripping member presses the noise reducing element first and then gradually picks up the noise reducing element from the head end portion 100' (see fig. 5 and related description of the patent specification), and since the pressed noise reducing element has a certain viscosity with the second conveyor belt, the method and apparatus disclosed in the patent have the following disadvantages: 1. the noise reducing element is difficult to grasp quickly from the second conveyor belt and can only be torn off the second conveyor belt gradually from one side first; 2. the first suction device (85) needs to continuously output suction force, and the waste of electric energy is large.
