Description

  The present invention relates to a tire ply manufacturing apparatus for manufacturing a tire ply from a long steel cord-containing rubber sheet material.

  In the manufacturing process of a pneumatic tire, a tire ply is manufactured by cutting a long steel cord-containing rubber sheet material in which a topping rubber is coated on an arrayed steel cord.

  Specifically, a long steel cord-containing rubber sheet material that has been conveyed linearly is cut at a predetermined length at an angle of 90 degrees with respect to the steel cord arrangement direction, and then the cut rubber The conveyance direction of the sheet material is changed by 90 degrees, and the side edges of the sheet material are lengthened by jointing to produce a tire ply. The manufactured tire ply is then wound on a roll or the like.

  Thus, in order to change the conveyance direction of the rubber sheet material by 90 degrees during the conveyance, the conventional tire ply manufacturing apparatus, as shown in FIG. From 31 toward the downstream side, the drawing device 32, the cutting device 33, the transfer conveyor 34, the joint device 35, and the winding device 36 are arranged in series in an L-shaped layout (for example, Patent Document 1).

  ADVANTAGE OF THE INVENTION According to this invention, the manufacturing apparatus of the tire ply which can further improve the productivity in the whole installation can be provided.

It is a top view which shows the layout of the manufacturing apparatus of the tire ply which concerns on one embodiment of this invention. It is the figure which expanded a part of manufacturing device of the ply for tires concerning one embodiment of the present invention. It is a top view which shows the layout of the manufacturing apparatus of the tire ply which concerns on other embodiment of this invention. It is a top view which shows the layout of the manufacturing apparatus of the conventional tire ply.

  Hereinafter, the present invention will be described based on the embodiments.

1. First Embodiment FIG. 1 is a plan view showing a layout of a tire ply manufacturing apparatus according to the present embodiment. FIG. 2 is an enlarged view of a part of the tire ply manufacturing apparatus according to the present embodiment. As shown in FIG. 1, the tire ply manufacturing apparatus according to the present embodiment includes an original fabric let-off (raw fabric hook) 1 of rubber sheet material containing steel cords, and a rubber sheet material downstream from the original fabric let-off 1. And a cutting device 3 for cutting the rubber sheet material at an angle of 90 degrees with respect to the steel cord arrangement direction at the cutting position.

  The tire ply manufacturing apparatus is further arranged on the downstream side of the cutting device 3, and conveys the cut rubber sheet material to the left and right by the normal rotation or reverse rotation of the conveyor, and the conveying device. A conveyor 4 for further transporting the rubber sheet material sent from the joint to the joint position, and a joint device 5 for producing a tire ply which is elongated by sequentially jointing the side edges of the rubber sheet material at the joint position. And a winding device 6 for winding the formed tire ply.

  Each of the conveyor 4, joint device 5 and winding device 6 described above is arranged on each of the left and right sides of the conveyor A, and the tire ply manufacturing apparatus as a whole is configured in a T-shaped layout. .

  In this way, by configuring the entire tire ply manufacturing apparatus in a T-shaped layout, two joint devices 5 can be arranged for one cutting device 3. Therefore, as a result of the one-to-two relationship between the cutting device 3 and the joint device 5, the production capacity of the joint device is substantially increased up to twice in the entire tire ply manufacturing apparatus, and the cutting with high production capacity is achieved. It is possible to balance the production capacity of the apparatus, and it is possible to improve the productivity of the entire tire ply manufacturing apparatus.

  In addition, when the tire ply manufacturing apparatus according to the present embodiment is used, it becomes possible to cut rubber sheet materials having different widths, and the cut rubber sheet materials are transferred to the conveyor of the conveyor A. Two types of tire plies can be efficiently produced by appropriately sorting left and right by rolling or reversing.

  Note that the tire ply manufacturing apparatus according to the present embodiment can be suitably used particularly for manufacturing radial tire plies.

2. Second Embodiment In the present embodiment, as shown in FIG. 3, the conveying device A, the conveying conveyor 4, the joint device 5, and the winding device 6 shown in FIG. Another line is added.

  In this case, the rubber sheet material cut by the cutting device 3 can be transferred to the additional transfer device A by a suction device using a vacuum or a magnet. Since four joint devices 5 are arranged and tire plies can be manufactured even in an additional line, productivity can be further improved.

3. Effects of this embodiment As shown in the first embodiment and the second embodiment, the entire tire ply manufacturing device is configured in a T-shaped layout, and the same number of joint devices are provided in both the left and right directions of the transport device. By arranging, the productivity of the tire ply can be improved.

  When the tire ply was produced using the tire ply manufacturing apparatus of the first embodiment described above, it was confirmed that the productivity could be improved by about 30% in the cycle time for producing the tire ply.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to said embodiment. Various modifications can be made to the above-described embodiment within the same and equivalent scope as the present invention.
