Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wire alignment winding device that can wind a wire material such as a steel material or a cable having a circular cross-section or a deformed circular shape on a winding drum in an aligned state and can smoothly rewind the wire material.
[0002]
[Prior art]
When winding a wire in multiple stages on a winding drum, the wire wound around the drum and reaching the end of the drum is changed from the lower side to the upper side, but at this time, the direction and timing of switching are not accurately performed. Then, a situation occurs where the drum falls into the gap between the drum ridge and the wire or between the wires. In this case, if the wire rod that has fallen into the gap is pulled up only by the rotational force of the drum and is changed to an aligned state, the wire rod will return into the gap and an excessive force will be applied to the wire rod. Sometimes damage or disconnection occurs. Therefore, conventionally, a method has been used in which an operator waits beside the drum and manually aligns the wire when winding of the wire is likely to be disturbed.
[0003]
[Problems to be solved by the invention]
The relationship between the change of the drum and the wire will be described in detail with reference to FIGS. FIG. 9 is a development view of the state in which the wire A is wound around the drum D. The wire A is wound in the direction indicated by the arrow from the position of a, and (1) to (6) are windings of the wire A. Represents the order. L indicates a portion in which the wire A is placed in an oblique state in order to change from the lower winding stage to the upper winding stage (hereinafter abbreviated as the lower stage and the upper stage). FIGS. 10-i to 10-ni show the cross-sectional states of the wire A in Ha, Ha, and Ni.
[0004]
If the wire A is stepped instead the upper from the lower, FIG. 10 at the position of y wire rod A- ▲ 6 ▼ is depressed to wire A- ▲ 5 ▼ and pores B of the left flange D ₁ of the drum D, the wire A - ▲ 6 ▼ wire rod A- ▲ 5 ▼ angle alpha ₁ to overcome the rotational axis other side of the drum D to the wire a to large, i.e., unless an external force in the axial direction center side, of the drum D only rotational force will be wire a would be followed also wound along the left side flange D ₁ of the drum D, as shown by a broken line in Figure 10- (b). Therefore, the optimum position for switching the wire A to the upper side while shifting it obliquely with respect to the lower stage is a position that is about one quarter of the length L of the wire A to be in an oblique state as shown in FIG. Thus, the direction must be switched reliably, as shown by the solid line in FIG. 10-B to FIG. 10-D.
[0005]
Further, in the related art in which the wire A is wound around the drum D, when the drum D moves to the left along the rotation axis OO when the wire A is wound, the wire A has a drum. An inclination angle θ is generated in the switching direction between D and the guide pulley G (see FIG. 11). Then, when the inclination angle θ past the position of the wire A Guy as shown in FIG. 12 reaches a predetermined value, indicated by wires A- ▲ 6 ▼ (Figure 10 B in broken lines along the left side flange D _1. ) Is over the wire A- (5), the direction is switched. That is, when the wire rod A passes the position of (b), the angle α ₂ for the wire rod A- (6) to get over the wire rod A- (5) becomes small at the same time as the inclination angle θ increases, and it becomes easy to get over.
[0006]
If necessary, even if the direction of the wire A is changed only by the rotational force of the drum D at the time of changeover, the wire A falls into the gap B at the position shown in FIG. Winding is not realized. In order to surely switch the direction at the position shown in the figure, it is necessary to generate a sufficient inclination angle θ instantaneously at this position.
[0007]
The present invention has been made in view of the above-mentioned unsolved problems of the prior art, and by applying an external force at an accurate timing, the direction is changed at the time of switching, and the wire is wound in a state aligned with the drum. Accordingly, it is an object of the present invention to provide a wire alignment winding device that prevents the occurrence of catching between wires during rewinding, and that can improve work efficiency and prevent troubles such as disconnection.

The shaft insertion block 19 converts the rotational motion of the screw shaft 16 into linear motion, and the rewinding motion of the winding drum 1 in the direction of the rotational shaft is caused by reciprocating the movable base 4 on the support rollers 3 and 3. It is like that.
[0013]
Reference numeral 20 denotes a winding state detection device provided on the rotary shaft 1A of the winding drum 1, and the winding state detection device 20 has the current number of windings and winding for each winding stage of the wire A wound on the winding drum 1.

[0014]
Reference numeral 21 denotes a wire rod kicker for kicking the wire rod A in the direction opposite to the lower winding side winding direction of the wire rod A wound around the winding drum 1 . 22 and 22 are a pair of bearings constituting the wire rod kicker 21 and arranged on the floor F facing the front of the winding drum 1, and a sliding shaft 23 slides in the axial direction on the bearings 22 and 22. It is horizontal. Reference numeral 24 denotes a V-groove kick roller fitted to the sliding shaft 23, and a pair of return springs 25 in a state of being fitted to the sliding shaft 23 between the kick roller 24 and the bearings 22, 22. The kick roller 24 is returned to the middle of the bearings 22 and 22 together with the sliding shaft 23 by the spring force of each return spring 25. Reference numerals 26 and 27 denote left and right air cylinders installed on the floor F facing the shaft ends 23A and 23B of the sliding shaft 23.
