DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elongate winding device for rotating a winding drum to wind a long body (for example, a coated copper tube) around the winding drum, and a winding device for the same. It relates to the winding method used.

[0002]

2. Description of the Related Art In a conventional winding device, one winding drum is rotatably held by a base, and the winding drum is driven to rotate to wind a long body. Here, the winding drum has a cylindrical shape having a diameter corresponding to the diameter of a long body to be wound.

[0003]

However, in the conventional winding device described above, the long body is wound by the winding drum having one diameter, so that the winding device has a diameter corresponding to the diameter of the winding drum. Only a long body having an outer diameter or the like can be wound. In order to wind a long body having another outer diameter or the like, it is necessary to replace the winding drum with a winding drum having a diameter suitable for the other long body. This is troublesome and causes a reduction in the equipment operation rate.

In the above-mentioned conventional winding device, since the outer peripheral surface of the winding drum is a cylindrical surface having the same distance from the axis, when the long body is wound on the winding drum. When a gap is formed between adjacent elongated bodies, and when the elongated body is further wound around the outer periphery of the elongated body,
The phenomenon that the wound long body falls into the gap and pushes up the long body wound up in the lower layer occurs, and the long body loosens when the wound long body is removed from the winding drum. There is a problem that it easily collapses.

A first object of the present invention is to make it possible to tightly wind adjacent elongated bodies when the elongated body is wound on a winding drum, and to take up the wound elongated body. An object of the present invention is to provide a winding device and a winding method for a long body that can prevent the long body from being loosened and collapsed when removed from a winding drum.

A second object of the present invention is to provide a winding device for a long body which can selectively wind a long body having a plurality of outer diameters or the like by setting up in a very short time. .

[0007]

According to a first aspect of the present invention, there is provided an elongate winding device which rotatably holds a rotatably driven winding drum on a base and drives and rotates the winding drum. In a winding device for a long body that winds a long body around a winding drum, a regulating plate that is opened at one end of the winding drum when the long body is taken out is provided so as to be openable and closable; Is characterized by an inclined surface whose distance from this axis gradually decreases toward the regulating plate along the axis of the winding drum.

According to a second aspect of the present invention, there is provided a long body winding device according to the first aspect, wherein the base is rotatably provided, and the winding drum is mounted on the base. Several,
When the base is rotated, the winding start position of the long body in each of the winding drums is held so as to substantially coincide with each other.

According to a third aspect of the present invention, in the method for winding a long body, a regulating plate provided at one end of the winding drum so as to be openable and closable is closed.
The winding drum having an inclined surface whose distance from the axis gradually decreases as the outer peripheral surface moves toward the regulation plate along the axis is driven to rotate, and the long body is fed out in the axial direction and wound around the winding drum. It is characterized by taking.

[0010]

In the winding device for a long body according to the first aspect, the winding drum is driven to rotate, and the long body is wound on the winding drum. Here, the outer peripheral surface of the winding drum is an inclined surface whose distance from this axis gradually decreases as it goes to the regulating plate along the axis of the winding drum. The long body that has been taken moves toward the regulation plate side of the winding drum along the inclined surface, and the long body that is continuously wound moves outward, and the long body that has been wound up earlier. And the long bodies wound on the outer peripheral surface of this long body are wound closely together. In other words, the long bodies sequentially wound on the winding drum move outward and are tightly wound together with each other, and therefore, when the wound long body is removed from the winding drum, The winding state of the long body does not loosen and collapse.

According to a second aspect of the present invention, in the same manner as described above, the winding drum is driven to rotate so that the elongated body is tightly wound on the winding drum, and the wound length is wound. When the scale is removed from the winding drum, it does not loosen and collapse. Further, a base is provided rotatably, and a plurality of the winding drums are provided on the base so that when the base is rotated, the winding start position of the elongated body in each of the winding drums substantially coincides with each other. Since it is held, when winding a long body having a different outer diameter or the like, the base is rotated to position another winding drum at the supply section of the long body, and as described above,
The long body is wound around the other winding drum. Therefore,
Long bodies having different outer diameters and the like can be selectively wound by setup in an extremely short time.

According to the method for winding a long body according to the third aspect, the winding drum having the inclined surface whose outer peripheral surface is directed toward the regulating plate along the axis and whose distance from the axis gradually decreases is provided. Since the long body was wound up, the long body wound on the winding drum moved to the outside of the winding drum along the inclined surface, and the long body continuously wound was moved outside. To the side of the long body that has been wound up earlier, and is wound up. Therefore, when the wound up long body is removed from the winding drum, the winding state of the long body becomes loose. There is no collapse.

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

As shown in FIGS. 1 and 2, the winding device of this embodiment has a base 2 rotatably mounted on a shaft member 1, and two winding machines 3 and a winding machine 3 mounted on the base 2. The machine 4 is attached.

The structure of the winder 3 is as follows. That is, as shown in FIG. 3, a hollow shaft 6 is attached to the base 2 via a bearing 5, and the hollow shaft 6 is attached to a motor 7 fixed to the base 2.
Through a chain 8.

As shown in FIGS. 3 and 4, two plate-like members 9 arranged in parallel are fixed to the outer end of the hollow shaft 6 so as to rotate integrally with the hollow shaft 6. . One 9a of the plate-like member 9 is formed in a disk shape, and the other 9b is formed with a radially extending arm portion.
A plurality of regulating plates 11 are fixed to the peripheral edge of the plate-shaped member 9 via a connecting member 10 at a constant pitch in the circumferential direction. A cylindrical winding drum 12 is fixed coaxially with the axis of the hollow shaft 6 so as to connect the inner ends of these regulating plates 11. Here, the outer peripheral surface of the winding drum 12 is an inclined surface 12a whose distance from the axis gradually decreases as going outward along the axis.

As shown in FIG. 3, a cylindrical shaft 15 is spline-coupled into the hollow portion of the hollow shaft 6 by spline portions 15a and 15b formed on the outer periphery thereof. A guide block 18 that is reciprocated along a guide rail 17 by a cylinder 16 fixed to the base 2 is attached to the inner end of the shaft 15. A bearing 19 is interposed between the guide block 18 and the inner end of the shaft 15. As shown in FIGS. 3 to 5, levers 20 are fixed radially to the outer end of the shaft 15, and these levers 20 are swingably attached to the winding drum 12 by pins 21. It is connected to a link 22. These links 22
A restricting plate 23 is fixed to the tip of. When the shaft 15 is projected outward, this projected displacement is
The restricting plate 23 is transmitted to the link 22 via a line 0, and stands on the side surface of the winding drum 12, as shown by a two-dot chain line in FIG.

As shown in FIG. 6, since the winder 4 has the same structure as the winder 3, the same reference numerals as those of the winder 3 are used, and the description is omitted. However, in the winding machine 4, the radius of the plate member 9 is smaller than that of the winding machine 3, and accordingly, the radius of the winding drum 12 attached to the plate member 9 is also smaller than that of the winding machine 3. The lever 20 which is smaller and is provided inside the winding drum 12
Are smaller than those of the winder 4. This corresponds to two types of long bodies having different outer diameters and the like. In addition, when the base 2 is rotated around the shaft member 1, the winding start positions of the long bodies in the winding machines 3, 4 are set to be substantially in a positional relationship.

Next, the operation of the winding device of the present embodiment will be described, and a method of winding a long body according to one embodiment of the present invention will be described.

The base 2 is rotated around the shaft member 1 and the winding machine suitable for the outer diameter of the long body A among the winding machines 3 and 4 is located at the supply section of the long body A. Next, the guide block 18 is moved toward the inner end of the hollow shaft 6 by driving the cylinder 16 to contract. Thereby, the outer end of the shaft 15 protrudes outward. Due to this projection, the lever 20 attached to the shaft 15 projects outward,
The link 22 is moved to the left in the figure as shown in FIG. 4, and the regulating plate 23 fixed to the link 22 is raised. The restricting plate 23 stands up and faces the restricting plate 11 and protrudes from the side surface of the winding drum 12.

Next, the leading end of the elongated body A is inserted into a region surrounded by the regulating plates 11 and 23 and the outer peripheral surface of the winding drum 12, and the leading end is locked to the winding drum 12. Next, the motor 7
Is driven to rotate the hollow shaft 6. Then, the winding drum 12 is driven to rotate, and the elongated body A is wound on the outer peripheral surface of the winding drum 12. At this time, since the wound long body A has an inclined surface 12a whose outer peripheral surface is inclined outward, the regulating plate 23 extends along the inclined surface 12a.
And slides to the side to come into contact with the regulating plate 23. Further, when the winding is continued, the wound long body A sequentially moves along the inclined surface 12a, and when it is wound once, the long body A comes into contact with the side surface of the long body A in contact with the regulating plate 23. It is wound up in contact. Further, the elongate body A is wound while being circumscribed on the outer peripheral surface of the winding drum 12, and when the winding of one layer is completed, the elongate body A is wound around the outer periphery of the elongate body A of the first layer. Take it. Here, as described above, 1
Since the long bodies A of the layer are in contact with each other, the long body A wound on the first layer does not fall on the first layer,
It is wound up closely. In this way, the elongated body A is wound tightly without any gap in the direction orthogonal to the axis thereof.

When the elongate body A having a predetermined length is wound on the winding drum 12, the drive of the motor 7 is stopped and the cylinder 16 is driven to extend, and conversely to the above. Then, the shaft 15 is moved backward, the regulating plate 23 is lowered, and the side surface of the winding drum 12 is opened. Thereafter, the long body A wound on the winding drum 12 is taken out from the winding drum 12, bound, transported, and stored. Here, as described above, the long body A wound on the winding drum 12 is
Since it is wound tightly without any gap in the direction perpendicular to the axis, when it is removed from the winding drum 12, loosening is unlikely to occur, and the coil shape can be maintained.

In order to wind up the elongated body A having an outer diameter different from that described above, the supply of the elongated body A is temporarily stopped, and the base 2 is rotated around the shaft member 1. The other winding machine is located at the supply section of the elongated body A, and the elongated body A is wound in the same manner as described above. Thus, it is possible to correspond to the long body A having different outer diameters and the like by a simple operation such as simply rotating the base 2 around the shaft member 1,
The setup time can be greatly reduced, and the equipment operation rate can be greatly improved.
