Description

  The present invention relates to a wire rod supplying apparatus and a wire rod supplying method, and more particularly to a wire rod supplying apparatus and a wire rod supplying method for forming a constant length wire rod having a predetermined length and supplying the constant length wire rod to the next process.

  2. Description of the Related Art Conventionally, a wire supply device and a wire supply method for forming a constant length wire having a predetermined length and supplying the constant length wire to the next process are known. Hereinafter, this type of wire supply device and wire supply method will be described by taking as an example the manufacturing process of a carcass ply used for a pneumatic tire for a vehicle.

  Generally, a carcass ply is used for a pneumatic tire for a vehicle, and a plurality of constant length wires are implanted in the carcass ply (see, for example, Patent Document 1). The wire supply device and supply method used for the carcass ply will be briefly described. For example, in the example described in Patent Document 1, a plurality of thread-like elements supplied from a reel are placed in an extrusion molding machine in an aligned state. A strip-like element as a wire is formed by applying a rubber coating to the plurality of thread-like elements.

  Then, the front end of the strip-shaped element is gripped by the first gripping member that cannot rotate around the axis, and the gripping member is slid in this state to pull out the strip-shaped element having a predetermined length from the extrusion molding machine. . Subsequently, the rear end portion of the strip-shaped element drawn out to a predetermined length is gripped by the second gripping member, and the space between the strip-shaped element extrusion molding machine and the second gripping member is cut by the wire cutting member. Thus, a strip-like length is formed as a constant length wire that is a component of the carcass ply.

Japanese Patent Laid-Open No. 11-254906 (FIGS. 1 to 6)

  However, in the example described in Patent Document 1, for example, when a strip-like element is formed by twisting a plurality of thread-like elements, the strip-like element is sent out while rotating around an axis. However, as in the example described in Patent Document 1, in the configuration in which the tip end portion of the strip-shaped element is simply gripped by the first gripping member that cannot rotate around the axis, the strip-shaped element is allowed to rotate around the axis. There is a disadvantage that the tip of the strip-shaped element cannot be positioned in the delivery direction.

  Here, in order to allow positioning of the leading end portion of the strip-shaped element in the delivery direction while allowing rotation of the strip-shaped element around the axis, a first gripping member for gripping the leading end portion of the strip-shaped element is provided. It is conceivable to make the structure rotatable about an axis. However, the first gripping member for gripping the tip end portion of the strip-shaped element is configured to be rotatable around the axis, and thus the tip end portion of the strip-shaped element is allowed to rotate around the axis of the strip-shaped element. When positioning in the sending direction is enabled, there are the following problems.

  That is, when the strip-like element is pulled out from the extruder for a long time to form a relatively long strip-like length, the strip-like element is bent due to its own weight. When the strip-shaped element is bent in this manner, the strip-shaped element is danced (swayed and violated) by being sent out from the extruder while rotating around the axis.

  For this reason, when the strip-shaped element is cut and the strip-shaped length is grasped by the other gripping member, the tension of the strip-shaped length is loosened, and a mistake occurs when the strip-shaped length is subsequently implanted into the annular support. There arises a problem that the strip-like length cannot be reliably supplied to the annular support, which is the next process, such as the occurrence of a problem or the inaccuracy of implantation.

  Further, in the example described in Patent Document 1, a pair of gripping members are reciprocated to arrange strip-like lengths one by one on an annular support. Accordingly, the return path operation of the gripping member after the strip-like length is arranged on the annular support and returned to the original position is wasted. For this reason, it takes a long time to start the supply of the next strip length after the strip length is arranged on the annular support.

  Moreover, in the example described in Patent Document 1, the strip-like length is arranged on the annular support with only a pair of gripping members. For this reason, after the strip-shaped element is cut to form a strip-shaped length, after the strip-shaped length is arranged on the annular support, until the pair of gripping members return to their original positions, The extruder had to wait for delivery of the strip-like element. Therefore, even if the feeding of the strip-shaped element from the extruder is stopped, the time required to start the supply of the next strip-shaped length after the strip-shaped length is arranged on the annular support. become longer.

  The present invention has been made in view of the above circumstances, and its purpose is to prevent loosening of the tension of the constant length wire rod even when the wire rod is fed while being rotated around the axis from the wire rod feeding means. Accordingly, an object of the present invention is to provide a wire rod supply device and a wire rod supply method capable of reliably supplying a constant length wire rod to the next process.

The second clamping hand 66 and the second roller hand 68 are on the constant length wire forming part 26 side. At the same time, the constant length wire conveyance device 14 further moves the first clamping hand 60 and the first roller hand 62 in the direction of separating from each other along the longitudinal direction of the constant length carcass cord 24C, and the second clamping hand 66. The second roller hand 68 is further moved in a direction approaching each other.

  At this time, in the present embodiment, one side of the constant-length carcass cord 24C is clamped by the first clamping hand 60 so as not to move relatively in the longitudinal direction, and the other side of the constant-length carcass cord 24C is clamped by the first roller hand 62. Thus, it is clamped so as to be relatively movable in the longitudinal direction and to provide resistance to relative movement in the longitudinal direction. Accordingly, in this state, tension is applied to the constant-length carcass cord 24C by moving the first clamping hand 60 and the first roller hand 62 by center distribution in a direction away from each other along the longitudinal direction of the constant-length carcass cord 24C. The fixed-length carcass cord 24C is extended.

  In this embodiment, the constant length carcass cords 24 </ b> A to 24 </ b> C are conveyed by the constant length wire conveying device 14 to the constant length wire conveying device 16 in a stretched state. Accordingly, even when the carcass cord 24 is sent out from the wire sending device 12 while rotating around the axis, by preventing the tension of the fixed-length carcass cords 24A to 24C from being loosened, an annular body 72 as the next step is used. Thus, it is possible to reliably supply (plant) the fixed-length carcass cords 24A to 24C.

Therefore, the fixed-length carcass cords 24A and 24C are reliably stretched because they are sandwiched so as to be movable and a resistance is applied to the relative movement in the longitudinal direction. Similarly, when the fixed-length carcass cord 24B is conveyed by the second clamping hand 66 and the second roller hand 68, the fixed-length carcass cord 24B is surely expanded.

  Further, in the present embodiment, the constant length wire material transfer device 16 that receives the constant length carcass cords 24A to 24C conveyed to a predetermined position by the constant length wire material conveyance device 14 and transfers them to the annular body 72 as the next process. Is provided. Therefore, the constant length carcass cords 24A to 24C conveyed to a predetermined position by the constant length wire conveying device 14 can be supplied to the annular body 72 as the next process by the constant length wire conveying device 16.

  In addition, while the constant length carcass cord 24A is being transferred to the annular body 72 by the constant length wire material transfer device 16, the constant length wire material transport device 14 proceeds to preparation for forming the next constant length carcass cord 24B. can do. Thereby, the supply efficiency to the annular body 72 of the fixed length carcass cords 24A to 24C can be improved.

  Further, in the present embodiment, while the first clamping hand 60 and the first roller hand 62 complete the conveyance of the fixed length carcass cord 24A to the fixed length wire material transfer device 16 and return to the original position (further, The second holding hand 66 and the second roller hand 68 are configured to carry the next constant length carcass cord 24B to the constant length wire transfer device 16 (in preparation for the conveyance of the constant length carcass cord 24C).

  Accordingly, the first clamping hand 60 and the first roller hand 62 complete the conveyance of the constant-length carcass cord 24A to the constant-length wire transfer device 16 and return to the original position (the conveyance of the next constant-length carcass cord 24C). The operation of the return path of the constant length wire conveying device 14 is used for the conveyance of the next constant length carcass cord 24B to the constant length wire conveying device 16 by the second clamping hand 66 and the second roller hand 68. Not.

  For this reason, the time required from the delivery of the constant length carcass cord 24A to the constant length wire rod transfer device 16 to the transfer of the next constant length carcass cord 24B can be shortened as compared with the conventional case. Thereby, it becomes possible to improve the wire supply efficiency to the annular body 72 of the fixed length carcass cords 24A to 24C.

  Further, in the present embodiment, the wire feeding device 12 returns to the original position after the first clamping hand 60 and the first roller hand 62 complete the conveyance of the fixed length carcass cord 24A to the fixed length wire material transfer device 16. The carcass cord 24 having a length necessary for forming the next constant-length carcass cord 24C is sent in between (while the next constant-length carcass cord 24C is prepared for conveyance).
