Description

  The present invention relates to a wire winding device that winds a conveyed wire.

  In the spring steel production line, each process such as quenching and tempering is applied to the spring steel while the spring steel is unwound from the take-up roll and transported downstream, and the spring steel that is transported after the process is finished is wound on the wire. It is wound up by a take-up device (for example, see Patent Documents 1 and 2).

  By the way, for the winding of a large-diameter and heavy wire such as spring steel by a winding device, aligned multilayer winding is desirable from the viewpoint of bundling safety and the like. This aligned multi-layer winding of the wire is arranged by shifting the winding position of the wire in the winding width direction, and reversing the shift direction of the winding position of the wire when the winding position of the wire is shifted to the end of the winding width. This is done by forming an aligned wire layer on top of the other layer.

  Here, the wire is transported along the wire production line along a certain transport path, and the transport position is shifted by the winding width before the wire winding device.

  However, a wire with high hardness such as spring steel is difficult to bend, and in order to shift the winding position of the wire by the winding width, the distance from the shift start position of the wire to the wire winding device must be increased. The production line becomes long.

In addition, when winding a wire around a winding drum, the wire that was straight before winding is wound around the winding drum while it is bent. Cannot be done and the diameter of the winding drum must be increased. Further, in order to bend the wire to a curvature that can be wound around the winding drum, the wire must be sent to the wire winding device at an inclination, and the installation height of the winding drum needs to be increased. For this reason, there existed a problem that a wire winding apparatus enlarged.

  The wire rod winding device 10 according to the present invention in the spring steel 12 production line will be described.

  As shown in FIGS. 1 to 3, the wire winding device 10 includes two pieces extending in a direction (hereinafter referred to as a traverse direction) orthogonal to a direction in which the spring steel 12 is conveyed (hereinafter referred to as a conveyance direction). A traveling path 16 provided with rails 18 and a traveling body 14 traveling on the traveling path 16 are provided. The traveling path 16 includes a base 20 with two rails 18 attached to the upper surface, a motor 22 fixed to one end of the base 20 in the traverse direction, and the other end side in the traverse direction from the motor 22 (hereinafter referred to as the front side). A ball screw 24 protruding to the side is provided.

  The traveling body 14 includes a base plate 26 that can slide on the rail 18. A moving body 26A that moves in the traverse direction by the rotation of the ball screw 24 is attached to the base plate 26, and the base plate 26 moves forward (in the direction of arrow A in the figure) when the motor 22 rotates in one direction. It travels and moves to the rear side (in the direction of arrow B in the figure) as the motor 22 rotates in the other direction.

  A support column 28 is erected on the upper surface of the base plate 26. A rotating shaft 30 extending to both sides in the traverse direction is rotatably supported on the support column 28, and a cylindrical winding drum 32 is attached to the front side of the rotating shaft 30.

  A sprocket 34 is attached to the rear side of the rotating shaft 30, and a motor 36 is attached to the upper surface of the base plate 26. A sprocket 38 is attached to the rotation shaft of the motor 36 side by side with the sprocket 34, and a chain 40 is wound around the sprockets 34, 38.

  As a result, when the winding drum 32 rotates in the direction in which the spring steel 12 is wound by the rotation of the motor 36 with the spring steel 12 being pressed against the winding drum 32 by the holding means (not shown), the winding is performed. The spring steel 12 is wound around the circumferential surface of the body 32, that is, the winding surface 32A.

  Here, the traveling body 16 can be moved in the traverse direction, that is, the winding drum 32 is traversed by shifting the relative position of the spring steel 12 conveyed along a certain conveying path with respect to the winding drum 32, and spring steel. This is because the multi-layer winding 12 is wound around the winding drum 32 in an aligned manner. Further, the traverse speed and direction of the winding drum 32 are controlled by a driver (not shown) of the motor 22 so that the spring steel 12 can be wound in an aligned multilayer manner.

  As shown in FIG. 4 (A), first, the winding drum 32 waits with the winding width regulating plate 44 aligned with the conveying position of the spring steel 12, and as shown in FIG. By rotating in one direction (arrow D direction in the figure), the winding drum 32 is traversed in the arrow A direction in the figure. The rotational speed of the motor 22 at this time is adjusted so that the winding drum 32 traverses the diameter of the spring steel 12 while the spring steel 12 makes one turn around the winding drum 32. Thereby, the winding position of the spring steel 12 can be shifted one row at a time, and the spring steel 12 can be aligned.

  As shown in FIG. 4C, when the winding width regulating plate 42 is shifted to the winding position of the spring steel 12, the traverse direction of the winding drum 32 is reversed in the direction of arrow E, and the aligned spring steel 12 is placed. Then, the spring steel 12 is aligned and wound on the layer, and when the winding width regulating plate 44 is shifted to the winding position of the spring steel 12, as shown in FIG. The traverse direction is reversed in the direction of arrow D.

  In this way, the winding position of the spring steel 12 is shifted by shifting the winding drum 32 with respect to the spring steel 12 conveyed along a certain conveyance path. For this reason, it is necessary to determine the distance from the most downstream transport roll pair 230 that transports the spring steel 12 to the wire winding device 10 to the wire winding device 10 in consideration of the shift amount of the winding position of the spring steel 12. Absent. Therefore, in the production line of the wire material having high hardness such as the spring steel 12 which is difficult to bend, the distance from the pair of conveyance rolls 230 on the most downstream side for conveying the spring steel 12 to the wire material winding device 10 to the wire material winding device 10 is shortened. And the overall length of the production line can be shortened.

  Further, since the winding steel 32 is reciprocated to wind the spring steel 12 in an aligned multilayer manner, the safety of the binding can be ensured.

  Further, since the base plate 26 on which the support column 28 for rotatably supporting the winding drum 32 is shifted, a complicated mechanism for moving the winding drum 32 to and away from the support column 28 is provided. This is unnecessary, and the structure of the wire rod winding device 10 can be simplified.

  Next, the bending roll 11 which curves the conveyed spring steel 12 to a predetermined curvature and guides it around the winding drum 32 will be described.

  As shown in FIGS. 1 and 3, the bending roll 11 is disposed between the winding drum 32 and the transport roll pair 230 disposed on the most downstream side in the transport direction. The bending roll 11 is constituted by two lower rolls 11A and an upper roll 11B arranged in a staggered manner along the conveying path of the spring steel 12, and the upper roll 11B is supported by a cylinder 13 so as to be movable up and down. Has been.

  The winding drum 32 is arranged above the conveying path of the spring steel 12, and the spring steel 12 is sent to the back side of the winding drum 32 from the bending roll 11 and is sent by a pressing means (not shown). The cylinder 32 is pressed against the winding surface 32A. Then, when the winding drum 32 rotates in the direction of arrow C, the spring steel 12 is bent around the winding drum 32 and wound around the winding drum 32.

  Here, the spring steel 12 is initially bent by the bending roll 11 before being bent by the rotation of the winding drum 32.

  As shown in FIG. 5A, the spring steel 12 is conveyed straight by the conveyance roll pair 230 and enters the bending roll 11. Then, as shown in FIG. 5B, when the sensor (not shown) detects that the tip of the spring steel 12 has passed the bending roll 11, the upper roll 11 </ b> C is lowered by the cylinder 13. As a result, as shown in FIG. 5C, the conveyed spring steel 12 is curved to a predetermined curvature and guided around the winding drum 32.

  Therefore, the curvature that must be applied to the spring steel 12 by the rotation of the winding drum 32 is reduced, and the diameter of the winding drum 32 can be reduced. Moreover, the inclination angle of the spring steel 12 sent to the winding drum 32 can be reduced, and the installation height of the winding drum 32 can be reduced. Therefore, the wire winding device 10 can be downsized.

  Further, since the spring steel 12 is bent by the bending roll 11, the spring steel 12 can be bent without stopping the conveyance of the spring steel 12 and without scratching the spring steel 12.

  In the present embodiment, the bending means has been described taking the bending roll 11 as an example, but other methods such as bending the wire by passing it through the R path are also applicable. In the present embodiment, the present invention has been described by taking the winding of spring steel as an example.
