Description

Description: TECHNICAL FIELD The present invention relates to a continuous feeding method for a belt-shaped winding member and an apparatus therefor, more specifically, a belt-shaped material used as a tire constituent material, for example, a plurality of cells. The present invention relates to a continuous winding method and apparatus for a strip-shaped winding member that automatically and continuously feeds a strip-shaped winding member without taking up a large space and efficiently performing the feeding work.

[Conventional technology]

Conventionally, in the case of using a band-shaped material as a tire constituent material in a tire molding process, a band-shaped material having a constant length is wound around a cell in a coil shape in advance, and a plurality of such band-shaped winding members are fixed. A method has been performed in which the strip-shaped material is sequentially fed out from the strip-shaped winding member located on the tip side of the fixed spindle by being passed through the main spindle, and is continuously fed by being connected to the next strip-shaped material (JP-A-60- 137749 publication).

[Problems to be solved by the invention]

However, in the case of the conventional device as described above, when the strip-shaped material is sequentially unwound from a plurality of strip-shaped winding members inserted through the fixed main shaft, the strip-shaped winding member at the unwinding position and the strip-shaped winding member adjacent thereto are wound. A collar is interposed between the cells to prevent co-rotation with the take-up member, but when setting a plurality of strip-shaped take-up members (for example, 10 or 20) to the fixed spindle first, Since it is necessary to insert such a collar alternately between the strip-shaped winding members, and after the unwinding is completed, the empty cell and the collar must be separated and accommodated, which requires a lot of time and labor. There was a problem saying that it required.

In the case of the conventional device as described above, the strip-shaped material is unwound from the strip-shaped winding member located on the tip side of the fixed main shaft, and when the unwinding is completed, the next strip-shaped winding member is unwound. Since it is a method of starting the unwinding by moving it to the position, an accurate pitch feed mechanism is required for unwinding the band-shaped winding member, the apparatus itself becomes complicated, and the band-shaped material is removed from all band-shaped winding members. Since it is necessary to hold multiple empty cells on the fixed spindle until unwinding,
There is a problem that a wide space is required for horizontally moving the device itself.

The present invention has been devised in view of such conventional problems. It accurately feeds a plurality of strip-shaped winding members to the unwinding position with a simple structure and automatically discharges empty cells. Accordingly, it is an object of the present invention to provide a continuous feeding method of a belt-shaped winding member and an apparatus thereof which can efficiently feed a belt-shaped material in a narrow space.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention has a stopper member for bringing a strip-shaped winding member for unwinding into contact with the tip side of a hollow cylindrical fixed main shaft that supports a plurality of strip-shaped winding members,

It is configured to be rotatable in a direction orthogonal to the direction, and provided inside the distal end of the hollow cylindrical fixed main shaft is a rotation preventing means for preventing rotation of the strip-shaped winding member adjacent to the unwinding position of the strip-shaped winding member, The rotation preventing means is constituted by an expanding means slidably mounted on a fixed main shaft whose tip outer periphery is divided into a plurality of parts, and a band-shaped winding member is sequentially moved onto the fixed main shaft to a supporting shaft at an unwinding position. The gist of the invention is to provide a sending-out means for sending out and to provide a position detecting means for detecting the strip-shaped winding member abutting on the stopper member and controlling the sending-out means.

[Operation of the invention]

The present invention is configured as described above, and a plurality of belt-shaped winding members fitted and inserted in the fixed main shaft are brought into contact with the stopper member provided at the unwinding position on the tip end side of the fixed main shaft, and are projected and retracted from the end surface of the stopper member. Are sequentially fed onto the supporting shaft, and at the time of unwinding of the strip-shaped material, the strip-shaped winding member positioned at the unwinding position is prevented from co-rotating with the strip-shaped winding member adjacent to the unwinding position. Unwinding, and at the stage when the unwinding of the band-shaped material is completed, the supporting shaft is retracted so that the empty cell is automatically dropped and removed from the unwinding position,
The support shaft is again projected to the tip side of the fixed shaft, and the next strip-shaped winding member is sent to the unwinding position on the support shaft, and the rear end of the previously stripped strip-shaped material and the tip of the latter strip-shaped material are separated. By connecting and sequentially feeding the band-shaped material, the band-shaped material used as a tire constituent material is automatically fed from a plurality of cells,

Further, as shown in FIG. 4, at the tip of the fixed main shaft 4, a rotation prevention for preventing the rotation of the next strip-shaped winding member 3 adjacent to the strip-shaped winding member 3 at the unwinding position X is provided. Means 10 are provided. The rotation preventing means 10 has a protrusion 11 formed at the tip of the fixed spindle 4 for expanding and crimping the inner surface side of the cell 2 of the strip-shaped winding member 3 to be wound next, and inside the tip of the fixed spindle 4. , Tapered expansion / contraction hole 12 is formed,
The outer periphery thereof is divided into a plurality of parts so that they can be expanded and contracted.

Inside the tapered expansion / contraction hole 12, there is accommodated a top 13 which is a slidable taper expansion means, and one end of the top 13 is a through hole formed in the fixed main shaft 4. It is connected to a rod 15 inserted through the hole 14, and the rod 15 is
It is connected to a cylinder 16 installed on the frame 1.

Therefore, when the cylinder 16 contracts, the tapered piece 13 is pushed into the tapered expansion / contraction hole 12 via the rod 15, and the projection 11 at the tip of the plurality of divided fixed spindles 4 is expanded. Then, the strip-shaped winding member 3 to be unwound next is brought into close contact with the inner surface side of the cell 2 to prevent the strip-shaped winding member 3 from standing around.

Further, the fixed main shaft 4 is provided with a feeding means 17 having an L-shaped cross section for sequentially feeding the plurality of strip-shaped winding members 3 onto the support shaft 6 at the unwinding position X.
