BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable winder used to wind power cables, wires and the like.

[0002]

2. Description of the Related Art A conventional cable winder, which is used to wind a cable or wire into a bundle, is a radial winding consisting of a plurality of winding drums provided at both ends of a winding cylinder provided on a rotary shaft of a rotary drive machine. After the cable and wire are wound around the outer circumference of the winding cylinder to bind them, the blade located at the tip of the rotating shaft is folded and the cable and wire are pulled out from the winding cylinder.

[0003]

However, in the above-described conventional winding machine, since the winding cylinder does not have a reduced diameter, the cable or wire must be extracted while the weight thereof is being applied, which makes the extraction work difficult. Since a plurality of blades must be folded individually, there is a problem that the extraction work takes time and effort.

Therefore, an object of the present invention is to provide a cable winder which can easily and efficiently remove a wound cable or wire.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention fixes an end plate member to a central shaft that is connected to a main shaft of a rotary drive mechanism, and attaches the end plate member to one surface side of the end plate member. In order to be able to tilt toward the central axis from the state parallel to the central axis, a plurality of winding blades pivotally fixed at one end to the end plate member are attached in a circular arrangement centered on the central axis, A moving member that moves forward and backward in the axial direction when the handle rotates is provided on the central shaft, and the moving member and each winding blade are connected by an arm so that the winding blade swings when the moving member moves forward and backward. It was done.

[0006]

With the winding vane group parallel to the central axis, a cable or wire is wound around the outer periphery of the winding vane group and tied with a string or the like, and then the handle is rotated to move the moving member to the end plate member side. When it is moved to, the tip of each take-up blade is pulled by the arm, and the take-up blade gathers on the central axis side around the pivot stop point to the end plate member to reduce the diameter and remove the cable or wire as it is. You can

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the rotary drive mechanism 1 is constructed such that a horizontal main shaft 3 is rotatably supported by a bearing 4 on an upper portion of a casing 2, and the main shaft 3 is driven by a motor 5. A cable winder 6 is attached to the tip of the main shaft 3.

The cable winder 6 has a central shaft 9 fixed to the tip of the main shaft 3 with flanges 7 and 8 in a coaxial extension with bolts, and an end plate member 10 fixed to the flange 8 of the central shaft 9. A plurality of take-up blades 11 attached to one surface of the end plate member 10, a moving member 12 attached to the central shaft 9, and an arm 13 for connecting the take-up blades 11, and a moving member 1.
It is composed of an operating mechanism 14 provided on the central shaft 9 for moving the 2 forward and backward.

As shown in FIG. 2, the end plate member 10 has six arm plates 15 fixed to the outer periphery of the flange 8 in a radial arrangement.
And a connecting member 16 that joins the ends of the arm plates 15 to each other to form a hexagon, and the winding blade 11 is attached to the front surface of each arm plate 15.

As shown in FIGS. 1 and 4, the winding blade 11 is formed in a U-shape in plane by using a reinforcing bar, and the folded front end side is bent outward and the rear end portion is fixed to the arm plate 15. It is attached to a hinge 17 provided by a pivot 18, and is swingable around this pivot 18.

As shown in FIG. 2, the winding blades 11 are arranged in a circle around the central axis 9 and oscillate with respect to the central axis 9.

As shown in FIG. 3, the operating mechanism 14 provided on the central shaft 9 has a screw shaft 19 inserted into the hollow central shaft 9 and rotatably attached thereto. Fix the handle 20 for turning operation to the tip protruding from
A nut 21 that is screwed into the screw shaft 19 is housed inside the central shaft 9, and a moving member 12 that is externally fitted and inserted into the central shaft 9, and the nut 21 includes an elongated hole 22 formed in the central shaft 9 in the axial direction. The moving member 12 is moved forward and backward in the axial direction of the central shaft 9 by rotating the screw shaft 19 with the handle 20 by being joined together.

The moving member 12 and the tip end side of each winding blade 11 are pivotally connected by an arm 13, and the winding blade 11 swings around a pivot 18 as the moving member 12 moves back and forth.

When the moving member 12 is located on the tip side of the central shaft 9, each winding blade 11 becomes parallel to the central shaft 9 as shown by the solid line in FIG. 1, and is held in the winding posture of the cable or wire. When the moving member 12 is moved to the end plate member 10 side, the winding blade 11 is pulled and tilted by the arm 13 so that the tip end side approaches the central shaft 9, as shown by the alternate long and short dash line in FIG. The diameter of the arrangement is reduced, and the cables and wires are in a pulling posture.

The cable winder of the present invention is constructed as described above. To wind a cable or wire, the handle 20 is operated to position the moving member 12 on the tip side of the central shaft 9, Each winding blade 11 is made parallel to the central axis 9 by the arm 13.

In this state, the motor 5 of the drive mechanism 1 is started, the cable winder 6 is rotated through the main shaft 3, and the cables and wires are wound around the outer circumference of the winding blade 11 group.
When a predetermined length is wound, the motor 5 is de-energized, the cable winder 6 is stopped, and the cables and wires are bound with a string or the like.

Next, the handle 20 is operated to move the moving member 1.
When 2 is moved to the end plate member 10 side, the arm 13 pulls the leading end side of the winding blade 11 toward the central axis 9 side, and all the winding blade 9 groups tilt at the same time to reduce the diameter of the leading end side. The wire can be pulled out as it is.

[0019]

As described above, according to the present invention, when the handle is rotated after winding the cable or wire, all the winding blades simultaneously tilt and the tip side becomes small in diameter. Extraction after winding is extremely easy and efficient, and even heavy cables and wires can be easily extracted.
