Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a supply device for supplying tire constituent materials to a forming drum.

This kind of conventional supply device separates the liner from the tire constituent materials by installing a separate roll in close proximity to the unwinding roll that wraps the tire constituent materials and the liner.
The tire constituent materials are placed on rolls or the like and pulled out to the forming drum.

Since the distance from the separating roll to the forming drum is long in such an apparatus, there is a drawback that the tire constituent materials after the liner has been separated may be stretched or wrinkled, or the materials may stick together. By providing a separate roll close to the forming drum, the present invention allows the liner to replace the conveyor belt, making it easier to unwind the material, and preventing the material from spreading and wrinkling. The purpose is to provide a feeding device.

Embodiments of the present invention will be described in detail below with reference to the drawings. Reference numeral 1 designates a frame of the supply device A, and its base plate 2 is placed on wheels 4 that roll on rails.

A desired number (four in the illustrated example) of unwinding rolls 5 are installed in the frame 1 in a stepped manner. A liner take-up roll 6 is provided in front of the unwinding roll 5. A separate frame 7 is provided at the front of the base plate 2, and separate rolls 8 are provided on this. This separate roll 8 is close to a forming drum 9 installed at the front of the apparatus A. The liner take-up roll 6 is driven by a drive motor 10 via a chain 11, a sprocket 12, and a clutch 13. The base plate 2 has a driving device 14 installed on the floor.
is connected to. This drive device 14 may be any means, such as a combination of a motor and a screw shaft, or a cylinder. In each of the unwinding rolls 5, different types of tire constituent materials 15 are inserted into a liner 1 made of J cotton or chemical fiber woven fabric to prevent adhesion.
6 and is rolled into a roll. Next, to explain the operation, when unwinding for the first time, pull out the excess liner end from the unwind roll 5 and separate it from the separate roll 8.
Then, the drive motor 10 is activated and the clutch 13 is engaged to rotate the take-up roll 6, and when the tire constituent material 15 is pulled out to the position of the separate roll 8. Disengage clutch 13.

When winding the tire constituent material 15 around the forming drum 9, by engaging a predetermined clutch 13, the tire constituent material is pulled by the liner 16, and the separate roll 8
It is supplied onto the forming drum 9 while being separated.
In this case, since the liner 16 is integrated with the tire constituent material 15 between the unwinding roll 5 and the separate roll 8, the tire constituent material is conveyed together with the liner. In other words, the liner 16 functions as a conveyor belt. As described above, in the apparatus of the present invention, since the separate roll 8 is provided close to the forming drum 9, the unwinding roll 5
The tire constituent materials are conveyed together with the liner during the period from 1 to 8 to the separate rolls 8.

Therefore, since almost no tension is applied to the tire constituent materials, the materials are prevented from stretching, wrinkles are also prevented, and there is no fear that different types of materials will stick together. The fact that there is no risk of sticking means that there is no need to take up too much space for each stage of the unwinding roll 5, the liner winding 2 take-up roll 6, the separating roll 8, etc., and as a result, the entire device becomes more compact. It also has the advantage of having a large number of stages. In addition, since the material is always supported by the liner, when the apparatus is stopped during rest period 2, the material is prevented from stretching due to its own weight. Furthermore, in the device of the present invention, the entire device is moved on wheels 4, so that the device can be moved in the width direction of the forming drum 9 by the drive device 14 to supply tire constituent materials to any position on the drum. .

Therefore, there is no need to twist the material and wind it around the drum, the setting position of the unwinding roll 5 does not have to be exact, and there is no need to adjust the unwinding roll each time it is set. After the material 15 is wound around the forming drum, it is cut into a predetermined size, and the material remaining at the rear is transferred to the unwinding roll 5.
is reversed and rewound close to the separate roll 8.

Therefore, although not shown, it is preferable that each unwinding roll 5 is also provided with a drive source for rewinding. As described above, according to the present invention, by providing the separate roll close to the forming drum, the liner serves as a conveyor belt for conveying the tire constituent materials, and prevents the spread and wrinkles of the materials, as well as the bonding between the materials. This has the advantage of preventing sticking.
