DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 is a schematic plan view of a belt-shaped member manufacturing apparatus for carrying out the method for manufacturing a belt-shaped member, FIG. 2 is a side view taken along the line AA in FIG. 1, and FIG. 3 is a front view taken along the line BB in FIG. As shown in the figure, the belt-shaped member manufacturing apparatus 1 is provided with a cutting device 3 such as a cutter that cuts the belt-shaped member W into a specified width H in a transport device 2 such as a transport conveyor that transports the belt-shaped member W. On the carry-out end side, a free roller conveyor 5 having guide rollers 4 for positioning at both ends is installed in a direction orthogonal to the conveying direction X of the strip member Wa.
[0010]
On the free roller conveyor 5, it is mounted so as to be movable in a direction (Y direction) orthogonal to the conveying direction (X direction) of the strip member Wa, and moved parallel to the cutting blade 3a of the cutting device 3 A tray 6 made of a possible aluminum plate is installed.
[0011]
In the vicinity of the cutting device 3 of the transport device 2, an adsorption transfer means 7 having an adsorbing tool such as a vacuum pad for transferring the strip member Wa cut by the cutting device 3 onto the tray 6 is installed. The suction transfer means 7 is configured to be movable up and down, left and right, and back and forth while holding the strip member Wa by a moving mechanism (not shown).
[0012]
Further, a laminating device 8 for forming the strip-shaped member Wx for one tire by sequentially laminating the strip members Wa transferred on the tray 6 on the moving path of the tray 6, that is, on the free roller conveyor 5. The laminating device 8 is composed of a pressing member 8b that moves up and down via an elevating device 8a such as a cylinder and a receiving member 8c, and bonds the integer number of strip members Wa to one tire. A belt-like member Wx having a length L (a circumferential length of the forming drum: πd) is formed.
[0013]
Further, the tray 6 placed on the free roller conveyor 5 is connected to an intermittent feeding means 9 such as a cylinder for intermittently feeding the strip member Wa to the laminating position P of the laminating device 8 at every pitch. The surface of the tray 6 is subjected to surface treatment (not shown) by shot blasting or the like so that the strip member Wa is in an optimal contact state with the surface of the tray 6.
[0014]
As the belt-like member W, in addition to the carcass belt-like member used as a tire constituting material as in the embodiment of the present invention, the belt-like member W can be applied to a belt-like member of polyethylene material, aromatic polyamide fiber sheet, steel material, and organic fiber in general.
[0015]
Moreover, although the free roller conveyor 5 is arrange | positioned in the direction (90 degrees) orthogonal to the conveyance conveyor 2, it is not limited to this, It is also possible to arrange | position so that it may become 45 degrees-90 degrees, Further, the angle of the cutting blade 3a of the cutting device 3 can be adjusted within a range of 45 ° to 90 °. Thereby, it becomes possible to apply also to manufacture of a half radial tire.
[0016]
Next, the manufacturing method of the strip | belt-shaped member Wx is demonstrated by the above apparatuses.
First, the strip-shaped material W conveyed by the conveying device 2 is cut by the cutting device 3 to a specification width H of a tire molding machine drum (not shown), and the cut strip member Wa is conveyed to the front end side of the conveying device 2. .
[0017]
Then, the strip member Wa is sucked and held by the vacuum pad of the suction transfer means 7 and lifted, and the suction transfer means 7 is transferred onto the tray 6 and placed in a predetermined position.
[0018]
At this time, the rear end side of the strip member Wa already transferred on the tray 6 and the front end of the strip member Wa transferred by the suction transfer means 7 are abutted and positioned as shown in FIG. It has become a state. In this state, the tray 6 is fed one pitch to the bonding position P side of the bonding apparatus 8 by the intermittent feeding means 9 and is bonded by the bonding apparatus 8 here.
In addition, as for the bonding surface of the strip member Wa, it is desirable to heat at 60-80 degreeC by the warm air means which is not shown in figure.
[0019]
Then, as shown in FIG. 4 and FIG. 5, the above-described operation is repeated several times to form a belt-like member Wx for one tire by pasting so that the drum circumference (πd) is obtained, The belt-like member Wx placed on the tray 6 is transferred to the lower center of the molding machine drum together with the tray 6 and supplied to the molding machine drum.
[0020]
The belt-shaped member Wx for one tire formed on the tray 6 is not necessarily supplied to the molding machine drum, but is stocked together with the tray 6 or is transported to another molding process or the next process. It is also possible.
[0021]
As described above, in this embodiment, the strip member Wx of the strip-shaped material W cut into strips is transferred onto the tray 6 that can be moved by the suction transfer means 7 and bonded. In addition to the efficient transfer and transfer of Wa, the bonding accuracy and workability of the strip member Wa are improved, and the drum winding time per tire is shortened to improve productivity. It is possible to plan.
[0022]
【The invention's effect】
In this invention, since the strip member of the strip-shaped material cut into the strip shape as described above is transferred and pasted onto the movable tray by the suction transfer means, in the small-scale production method, the transport of the strip member and The transfer work can be performed efficiently, and the laminating accuracy and workability of the strip members are improved, and the drum winding time per tire can be shortened to improve the productivity. effective.
