Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a wire rod winding device, and more particularly to a rolled wire rod winding device for winding a rolled wire rod fed from a steel bar rolling mill into a winding reel. Regarding

(Prior art) There is a winding device that winds rolled steel strips such as wire rods into coil strips as the output side equipment of the strip steel rolling equipment. However, when winding in multiple layers on a wide take-up reel, the wire rods are placed on the reel. It is necessary to perform aligned winding so that the winding is performed evenly. In such a winding device, conventionally, a winding reel is axially reciprocated with respect to a wire material sent thereto to perform aligned winding. FIG. 6 is a plan view of a conventional winding device of this type. A traverse carriage 27 that reciprocates with a screw feeder 26 or the like is provided on a rail 25 laid on the base floor, a take-up reel 28 is pivotally supported on the carriage 27, and is similarly mounted on the carriage 27. The take-up motor 33 causes the take-up reel 28 to rotate in the take-up direction via the gear mechanism 31 to wind the wire rod 30, but at the same time as the take-up reel 28 rotates, the traverse carriage 27 causes the traverse motor 32 to move the rail 25 by the traverse motor 32. The wire reel 30 is reciprocally moved with a stroke of the reel width, whereby the take-up reel 28 traverses in a direction perpendicular to the feed line of the wire rod 30, and the wire rod 30 is wound on the reel 28 in an aligned state.

(Problems to be Solved by the Invention) In the above-described conventional aligning and winding device, since the winding reel side traverses the wire, the inertia during the U-turn of the reciprocating motion is large and the traverse speed can be increased. Therefore, the rotation speed of the take-up reel is limited, and the production efficiency does not increase. There is a problem in that the drive device for the traverse carriage that moves the take-up reel is required, the entire take-up device becomes large, and the overall cost becomes high.

According to the present invention, the wire rod is traversed without moving the main body of the device including the take-up reel, and the traverse device is installed separately from the main body so that the wire is not bent significantly. It enables high-speed winding while maintaining high tension.

(Means for Solving the Problems) A wire rod winding device according to the present invention comprises a pair of long barrel traverse rollers for sandwiching and guiding the wire rod and a long frame traverse roller connected to a roller frame for holding the long barrel traverse rollers. A wire rod traverse device equipped with a traverse drive mechanism for reciprocating a roller in parallel with the axial direction of the take-up reel, and a long cylinder arranged on the wire rod entrance side of the wire rod traverse device and extending parallel to the axial direction of the take-up reel. A tension roller, a swing arm that supports both ends of the long body tension roller, and a tension roller device that includes an arm urging device that urges and rotates the swing arm around an arm support shaft are provided on the inlet side of the wire rod winding machine main body. Is provided separately from the winder body, and the long body tension roller is provided by the biasing force of the swing arm. Is biased laterally to one side in the direction of extension of the wire rod so as to apply tension to the wire rod, and the planes including the cross sections of the long barrel traverse roller and the long barrel tension roller are mutually They are orthogonal.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a rolled wire winding device according to an embodiment of the present invention, and FIG. 2 is a front view of FIG. A winding machine main body A having a take-up reel 9 on the exit side of the bar mill 12 and a wire rod separate from the winding machine main body A and in front of (the entrance side of) the winding machine main body A. A traverse device B, and one side in the lateral direction with respect to the feeding direction of the wire, further in front of (entrance side) the wire rod traverse device B, a laterally long tension which is supported by a swing arm and applies upward tension to the wire rod in this embodiment. A roller (long-body tension roller) and a tension roller device T provided with an arm urging device for swinging the laterally long tension roller upward with respect to the wire are installed.

The winding machine main body A is attached to a winding motor 11, a two-stage switching speed reducer 10 connected to an output shaft of the winding motor, and a detachable mount on the output shaft of the speed reducer 10 by taper fitting. Take-up reel 9
It consists of and.

The wire rod traverse device B includes a pair of vertically long traverse rollers (long cylinder traverse rollers) 2 for sandwiching and guiding the wire rod 13 fed from the rolling mill 12, and the traverse roller 2 in the lateral direction with respect to the wire rod feed line L. And a traverse drive mechanism for performing a traverse operation. As shown in FIG. 3 and FIG. 4, the traverse roller 2 is rotatably mounted on the roller frame 3 via roller chocks 2a at both ends of the roller which are screwed to two screw shafts 2b which are mutually opposite screws. The roller frame 3 is pivotally supported, and further, the roller frame 3 is guided by a pair of guide rods 4 fixed to the traverse device body frame 1, and the traverse roller 2 is moved with a required stroke.
At the same time, the winding reel 9 is moved parallel to the axis of the winding reel 9 in order to cause the winding reel 9 to wind the winding wire 13 in an aligned manner against the tension of the winding rod. Each screw shaft 2b is axially supported by the roller frame 3 so as not to move in the axial direction, and the shaft ends on one side thereof are connected to each other via a sprocket 34 and a chain 35. One screw shaft 2b projects from the traverse device body frame 1 and extends outward, and by rotating this projecting end 2c with a hand tool or the like, the gap between the two traverse rollers 2 is removed by the wire rod 13
It can be adjusted according to the wire diameter. The roller frame 3 is connected to a rotation-reciprocating linear motion converting mechanism 6 (FIG. 1) via a tie rod 5 which is bolted to its back. As the rotation-reciprocation / linear motion converting mechanism 6, for example, a cam device including a cylindrical cam 17 and a cam follower 18 is effectively adopted. In this case, the tie rod 5 is a linear motion rod 16 that holds the cam follower of the rotation-reciprocating linear motion conversion mechanism 6.
Connected to. The conversion mechanism 6 converts the rotational drive of the cylindrical cam 17 by the traverse drive motor 8 and the speed reducer 7 into the reciprocal traverse motion of the cam follower 18 and the tie rod 5, and causes the linear traverse motion of the roller frame 3 and the traverse roller 2. By the traverse movement of the traverse roller 2 parallel to the take-up reel 9, the wire 13 sandwiched by the traverse roller 2 moves in the axial direction of the take-up reel 9 while being wound around the take-up reel 9, whereby the winding is performed in line. It As shown in FIG. 2, a laterally elongated tension roller 14 that applies tension to the wire rod 13 by lifting the wire rod 13 fed from below to the traverse device body frame 1 via swing arms 15 at both ends thereof. It is pivotally attached. The swing arm 15 has an intermediate portion pivotally attached to the main body frame 1 via an arm support shaft, and a lower end of the swing arm 15 constitutes an arm urging device for urging and rotating the swing arm 15 (see FIG. 2). Example) and is connected to the main body frame 1. Accordingly, the tension roller device T according to the present invention is constituted by the swing arm 15, the laterally elongated tension roller 14 and the arm biasing device in this embodiment. The swing arm 15 and the lateral tension roller 14 constantly elastically press the wire rod 13 from below by the action of the tension spring 15a, thereby eliminating the vertical deflection of the wire rod, and always applying an appropriate tension to the wire rod 13. There is. FIG. 5 shows a weight 1 instead of the tension spring 15a as a modification of the structure of the arm urging device.
9 is an example in which the weight 19 is connected to the tip of a pulling arm 23 extending from the arm support shaft 22 via a pulley 20 and a wire 21 which are pivotally supported on the apparatus main body frame 1, whereby the swing arm 15 is connected. The arm support shaft 22 is used as a fulcrum to urge it to rotate upward. Reference numeral 24 is a stopper when the pulling arm 23 pivots to the uppermost position.

Although the above embodiment is an example in which the take-up reel 9 is supported horizontally, the present invention can be similarly applied to the case where the take-up reel 9 is vertically supported on the base floor. In that case, The vertically long traverse roller 2 is a horizontally long traverse roller which is axially supported in a pair of upper and lower positions. Correspondingly, the horizontally long tension roller 14 is a vertically long tension roller which is parallel to the vertically oriented take-up reel. The pushing bias of the roller laterally with respect to the running direction of the wire causes tension in the wire. It is understood that such modifications are easy for those skilled in the art, and the present invention also includes the embodiments in this case.

(Effects of the Invention) As described above, according to the present invention, the wire rod traverse device for linearly moving the wire rod in the axial direction of the take-up reel and the long-body tension roller for applying tension to the wire rod laterally in the traveling direction are provided. Since the tension roller device is provided separately from the winding machine main body and only the rotating operation is performed on the take-up reel side, inertia during traverse U-turn can be reduced,
For example, traverse speed 50 while applying high tension to the wire at all times.
In addition to being able to perform line-up winding at a high speed of mm / sec or more, the tension control is easy and the tension device is simple, and since the wire rod is not bent or deformed significantly, damage to the wire rod is prevented.
