DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0010]
Figure 1 is a schematic plan view of a manufacturing apparatus of the carcass member for carrying out the production method of the carcass member, FIG. 2 is a front view of FIG. 1, FIG. 3 shows the enlarged sectional view of part A of FIG. The manufacturing apparatus 1 is provided with a conveying conveyor 3 for carrying in and conveying the belt-like material W, and a forming machine drum 4 orthogonal to the conveying conveyor 3 and having a diameter d on the leading end side at the unloading end side of the conveying conveyor 3. The laminating conveyor 5 is movable up and down around a supporting point O. The conveying conveyor 3 is provided with a measuring means 13 at the carry-in end, and a cutting device 2 for cutting the belt-like material W into a specified width H in the conveying direction at the intermediate portion.
[0011]
The strip member Wa of the strip-like material W cut by the cutting device 2 is sucked and held at the crossing portion X between the transport conveyor 3 and the laminating conveyor 5 and transferred onto the laminating conveyor 5 in the orthogonal direction. A positioning and laminating device 8 is provided on the laminating conveyor 5 for forming a carcass member Wx having a length L (πd) for one tire by laminating an integral number of strip members Wa. It is provided.
[0012]
The transfer device 7 includes a holding member 9 such as a suction pad that sucks and holds the strip member Wa, and a transfer means 10 such as a cylinder that transfers the strip member Wa to a predetermined position, and the positioning and bonding device 8 is transferred. It comprises a stopper 11 for positioning the strip member Wa that has come and a laminating means 12 such as a splicer for sequentially laminating an integer number of strip members Wa.
[0013]
Next, a method for manufacturing the carcass member Wx using the above apparatus will be described.
[0014]
First, the width h of the belt-shaped material W carried in by the conveyor 3 is measured by the measuring means 13 at the carry-in end, and then the belt-shaped material W having a specification width H corresponding to the axial direction of the molding machine drum 4 is measured by the cutting device 2 . Cut into lengths to form strip members Wa. Then the cut strip member Wa is conveyed to an end side of the rear of the conveyor 3, where it was sucked and held by the holding member 9 of the transfer device 7 onto the laminating conveyor 5 disposed in a direction perpendicular to the conveyor 3 In the state, it transfers by the transfer means 10, such as a cylinder.
[0015]
Then, the strip member Wa is brought into contact with the stopper 11 of the positioning and laminating device 8 and bonded by the bonding means 12 such as a splicer. Next, the stopper 11 and the bonding means 12 are separated from the strip member Wa and bonded. The mating conveyor 5 advances one pitch in the arrow direction V in FIG. 2 (the upper surface dimension J of the strip member Wa shown in FIG. 3), and thereafter repeats these operations to form a carcass member Wx having a circumferential length for one tire. To do.
[0016]
The carcass member Wx formed in this way is transferred to the lower center of the molding machine drum 4, and in this state, the tip end side of the laminating conveyor 5 is lifted by lifting means such as a lifting cylinder (not shown), and the tip portion of the carcass member Wx. Is pressed against the lower surface of the molding machine drum 4. In this state, the feed speed V of the lamination conveyor 5 and the rotational speed v of the molding machine drum 4, winding a carcass member Wx.
[0017]
In this embodiment, the front end side of the laminating conveyor 5 is raised to the lower surface of the molding machine drum 4 and the front end portion of the carcass member Wx is crimped. 4 can be lowered to crimp the tip of the carcass member Wx.
[0019]
In the present invention, the measuring means 13 is provided at the carry-in end of the conveyor 3, and the width h of the belt-like material W that is carried in is measured by the measuring means 13. As this measuring means, for example, an optical measuring means 13 can be provided. By measuring the width h of the strip-shaped material W by such a measuring means 13, and by laminating a plurality of strip members Wa on the laminating conveyor 5, the laminating is performed with high accuracy, and this laminating sheet shape By transferring the member Wx to the molding machine drum 4 and crimping it, the carcass member Wx can be wound around the molding machine drum 4 with high accuracy.
[0020]
As described above, in the present invention, to check the width h of the strip-shaped material W conveyed in advance, by setting the calculated a width h and the number of the strip members Wa to the circumferential length of the forming machine drum 4, the length of the fine adjustment and during splice on lamination conveyor 5, laminating a feeding speed V of the conveyor 5 is synchronized with the rotational speed v of the molding machine drum 4 it can be wound in a sheet-like member Wx Thus, the length L for one tire can be made to have high dimensional accuracy , and workability and productivity can be improved.
[0021]
【Effect of the invention】
Since the present invention is configured as described above, the following excellent effects can be obtained.
(a). In the band-shaped material laminating conveyor strip member laminated so that the drum circumference, by winding supplies the carcass member to the molding machine drum, laminating accuracy and workability of the carcass member Will improve.
(b) It is possible to improve the productivity by shortening the drum winding time per tire .
