The present invention relates to a tire manufacturing apparatus and a manufacturing method, and in particular, to improve the uniformity of the product by using an automated apparatus that is continuously processed by a series of facilities and to improve productivity while lowering the manufacturing cost due to the reduction of labor. A device for attaching and supplying steel belt reinforcement material for used tires and a method thereof.

In general, the tire manufacturing process is used to manufacture a tire by using a combination of the device industrial part and the assembly industrial part. Here, the processes other than the molding process have a degree of difference, but it is generally acceptable to view the device industrially. Do.

In this context, in the calendering process of the conventional tire manufacturing apparatus, the steel belt reinforcing material, the nylon full cover and the nylon edge cover, are rolls wound in the form of rolls in each material process. In the former nylon full cover method, as shown in FIG. 15, the operator cuts one cut (precut state) by the fixing pin 202 in the transport rack 201. Unfasten and pull it out by hand to attach it to a known belt drum, or not shown in the drawing.However, by using a motor, the belt drum is supplied by one cut in the loosening method due to friction between the drive roll connected to this motor and the nylon full cover. Manual attachment was used.

In addition, as shown in FIG. 16, the latter nylon edge cover method is wound with the driving rate 104 connected to the motor 203 by using the motor 203 and caught by the fixing pin 205. Due to the friction of the nylon edge cover, when the belt drum rotation switch is turned on / off, the motor 203 is also turned on and off to attach the steel belt reinforcement material to the belt drum. .

However, in the conventional nylon full cover method or the nylon edge cover method, both the operator determines the cover sheets with the naked eye and attaches them to the center or the edge of the steel belt, wherein the cover sheets are wound on the belt drum every one or two turns. There was a problem that the same force (tension, longitudinal stress or tension, etc.) was not applied uniformly by manual force when attached, which adversely affects the quality during the work, especially when working with two full turns of nylon full cover. When the cover is removed from the roll and transported, the cover sticks to each other or is twisted and partially stretched, and the bottom of the cover is exposed to the material, which causes the attachment work to take a long time as well as the uneven force variation. There was this.

In addition, even when the cover is attached to the belt drum, the attachment position is not constant according to the skill of the workers, so the reliability of the product quality is lowered, and the problem of worker's work reliability is increased by performing the manual work every time. there was.
