Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a laying winding device that sends a rolled wire rod onto a conveyor in a ring shape by a laying head, and particularly to a plurality of laying winding devices having different inclination angles. The present invention relates to a shift type laying winding device which is provided with an ing head so that a laying head having a required inclination angle can be selected and used.

(Prior Art) Conventionally, as a device for winding a wire rod sent from a finish rolling mill in a ring shape and sending it out onto a conveyor, a spiral wire rod passage is provided in a hollow quill shaft having an inverted conical tip. The tip of the passage is exposed at the tip opening of the quill shaft, and while the wire rod enters the wire rod passage from the rolling mill side, the quill shaft is rotated integrally with the passage and is discharged in a ring shape from the tip opening. A winding device called a laying head is known. In the horizontal type, the laying head is normally inclined within a range of 5 ° to 15 ° so that the tip opening side is slightly downward from the horizontal. It is desirable that the ring-shaped wire rods drop on the adjacent lower conveyor in a constant natural shape, but even with a laying head of the same shape and inclination angle, the wire rod material (strength), wire diameter, wire rod temperature, etc. Depending on the wire shape, the ring shape and the tilt angle of the wire rod on the conveyor differ. Therefore, in order to mount an appropriate spiral-shaped wire rod on the conveyor in an appropriate shape, it is necessary to change the inclination angle of the laying head according to the conditions at that time.

Conventionally, the tilt angle of the laying head is changed by installing one laying head on a tiltable base to change the tilt angle of the base, or by using a fixed base and a laying head installed on the fixed base. This has been dealt with by, for example, sandwiching a spacer for changing the tilt angle with the head base.

(Problems to be Solved by the Invention) In the above-described conventional horizontal laying and winding device, the inclination angle must be changed by inclining one support base installed on the path line of the wire rod. A lot of time is required for the work for changing the angle, which causes a decrease in the operating efficiency of the line. Further, since the shape of the laying head itself is the same even if the tilt angle is changed, there is a problem that it cannot be dealt with when the type of wire material such as the wire diameter changes greatly.

The present invention enables a laying head having a required inclination angle to be quickly positioned on a line only by a simple linear movement operation of a slide base, which allows a wide range of wire rods of various wire diameters and materials. It is an object of the present invention to provide a shift type laying winding device applicable to the.

(Means for Solving the Problem) A shift type laying and winding device according to the present invention comprises a plurality of laying heads having different tilt angles, which are installed on a moving base, and the tilting angle required by the moving operation of the moving base. The laying head with is positioned on the pass line.

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

1 is a plan view of a shift type laying and winding device according to an embodiment of the present invention, and FIG. 2 is a schematic view taken along line II-II of FIG. A pinch roll device 6 for feeding a wire rod to a laying head described later is installed on an exit path line of a finish rolling mill (not shown). On the exit side of the pinch roll device 6, a slide base 2 extending at a right angle to the pass line L is provided. The slide base 2 can reciprocate on rails on the base floor 8 directly or via rollers. Reference numeral 4 is a hydraulic cylinder for moving the slide base 2.

A plurality of slide bases 2, two in the illustrated embodiment, are provided on the slide base 2.
The laying heads 1a and 1b are mounted. These laying heads 1a and 1b have different inclination angles with respect to the horizontal plane. 3 and 4 are schematic side views of the laying heads as viewed in the longitudinal direction of the slide base. The laying head 1a shown in FIG. 3 has a tilt angle θ ₁ with respect to the horizontal plane, and the laying head 1b shown in FIG. 4 has a tilt angle θ ₂ and θ ₁ <θ ₂ .

On the base floor 8 supporting the slide base 2, a hydraulic clamp device 3 for clamping and fixing the side portion of the slide base 2 is provided. Further, as shown in FIG. 1, a Stelmore conveyor 5 that conveys a ring-shaped wire rod is installed on the discharge side of the laying head at the pass line L position. The motors 7a,
7b is also provided on the slide base 2.

In this configuration, when the apparatus is in operation, the laying head 1a having an appropriate inclination angle (eg, θ ₁ ) depending on the type of the target wire rod, for example, the material, wire diameter, strength, wire rod temperature, etc., is moved laterally of the slide base 2. Is operated on the pass line L. When changing the tilt angle, the hydraulic clamp device 3 is opened, the slide base 2 is unfixed, and hydraulic pressure is applied to the hydraulic cylinder 4, the slide base 2 moves on the rail due to the extension of the piston rod. When the laying head 1b having different inclination angles θ ₂ comes to the pass line L, the slide base 2 is stopped and hydraulic pressure is applied to the hydraulic clamp device 3 to fix the slide base 2. This completes the work of changing the inclination angle of the laying head.

Although the above-described embodiment is an example in which two laying heads are provided on the slide base, the present invention is not limited to two, of course, and an arbitrary number of laying heads may be provided, and only the tilt angle may be provided. Instead, laying heads having different shapes and sizes may be juxtaposed.

(Effect of the Invention) As described above, in the present invention, a plurality of laying heads having different tilt angles are arranged on one slide base, and the laying head is used in a line by the expansion and contraction operation of the hydraulic cylinder. Since it is possible to select arbitrarily,
Since the change of the inclination angle of the laying head is completed only in the operation time of the hydraulic cylinder and the hydraulic clamp device, there is an effect that the line operation stop time for the inclination angle changing operation can be shortened. The work can be done easily.
