Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for winding a wire or the like such as metal or plastic film around a winding core.
The present invention relates to a winding plate and a winding device.

[0002]

2. Description of the Related Art Conventionally, the following operations are generally performed when winding a wire material such as a metal or a plastic film around a cylindrical core as a core. First, a winding plate used for installing a cylindrical paper tube or an iron tube, which is a winding core of a linear material, in a winding device is installed on a rotary shaft of the winding device. Then, the winding core of the linear material is installed and pressed against the winding plate installed on the rotation shaft of the winding device. (Hereinafter, the winding core and the winding plate in this state will be referred to as a winding plate with a winding core.) Next, the tip of the linear material fed from the previous step is attached to the winding core. And by rotating the rotary shaft,
The winding plate with the winding core is rotated to start winding the linear material onto the winding core.

Further, as an example of winding the linear material, a wide strip material is cut (hereinafter referred to as a slit) in a previous process to form a plurality of parallel strip materials, and the plurality of parallel strip materials are formed. It is also practiced to wind up the filament material by the winding plate with the winding core provided in plural in parallel with the rotation shaft of the winding device.

As the winding of the wire material progresses, the coil diameter of the wire material on the winding core increases. And
The winding is completed when the coil-shaped wire material has a predetermined weight or length. When the winding of the filament material is completed, the winding plate with the core wound on the filament material is removed from the rotating shaft, and the coil material is wound with the winding plate with the core. By removing the, the coiled wire material as a product is manufactured.

The above-described method for manufacturing a coiled linear material has been pointed out as the first and second problems described below, and improvements have been proposed for each of them. First of all,
The work of removing the coil-shaped filament material from the winding plate with the core was performed by hitting the filament material on the core with a hammer or the like. And this work is a heavy labor requiring a large amount of force because the coiled wire material has a large weight.
There is a risk that the coiled wire material may suddenly drop during the work, and the coiled wire material may be damaged during the work. In addition, manufacture products with core specifications. There was a problem that it was impossible.

To solve this problem, for example, Japanese Patent Laid-Open Nos. 7-172707 and 2000-185853.
Discloses a winding plate having a structure in which the winding plate is divided into a large number of segments, and the segments move in a radial direction to expand or contract the entire outer circumference. By using this winding plate, it is possible to easily remove the coil-shaped wire material wound on the winding core together with the winding core, and easily obtain a product with a core. It is suggested that you can.

Secondly, when a plurality of wire rods slit and sent out in parallel in the preceding step are wound by a plurality of cores which are also parallel to each other, the above-mentioned rotary shaft of the winding device is used. It has been practiced to install a plurality of winding plates with winding cores, and to wind the filament materials all at once while rotating all of them at the same rotation speed. However, since the thicknesses of the plurality of parallel linear materials are not strictly uniform, the diameter of the coil wound with the thick linear material is smaller than that of the thin linear material if the winding is continued at the same number of revolutions. It becomes larger than the diameter of the wound coil. As a result, there is a problem that the tension applied to the thick linear material is increased and the thin linear material is tightly wound, while the thin linear material is loosely wound. In order to solve this, for example, Japanese Unexamined Patent Publication No. 4-288927 discloses a device that controls the torque in each winding core by a configuration including a hydraulic passage and a brake cylinder.

In this way, the winding of three parallel strips is started.

As the winding progresses, the difference in the thickness of each of the three strips begins to affect the winding process. That is, in this embodiment, as described with reference to FIG. 6, the strip 72 including the crown 75 is different from the other strips 7.
Since the thickness is larger than that of Nos. 1 and 73, the diameter of the strip wound around the winding core also becomes large. As a result, again in FIG.
If all the winding plates 100 with cores rotate at the same number of rotations, a strong tension is generated in the strip material having a large thickness, which causes defective products and failures.

However, according to the present invention, all the three winding plates 100 with cores are not fixed to the rotary shaft 50, but receive the rotary torque from the adjacent rotary members 64 via the frictional force of the sliding plate 65. As a result, when a strong tension is generated in the thick strip, the tension is transmitted to the winding plate 100 with a core that winds the strip, and when this tension exceeds the frictional force, the winding is performed. Slip via the sliding plate 65 starts between the member 100 and the rotating member 64 that applies a rotational torque to the winding member, and the number of rotations of the winding core-equipped 100 plate decreases. As the number of revolutions decreases, the tension generated in the thick strip also decreases, and thereafter, the winding plate 1 with the core 1
00 continues rotating at a rotational speed in a state where the tension and the frictional force are balanced.

As described above, the winding plate 100 with the winding core, the sliding plate 65, the rotating member 64, and the spacer 61, which are sandwiched in advance between the former-side spacer sandwiching portion 51 and the front-side spacer sandwiching portion 52. , 62, 63 by just setting the pressing force along the axial direction of the rotary shaft 50 to an appropriate value, even if tension that causes an abnormality is generated in the strip material during winding, this is alleviated. can do. Then, it is possible to easily readjust the pressing force of the front side spacer holding portion 52 while observing the winding state of the strip material.

When the winding operation is completed, the front spacer holding portion 52 is removed from the rotating shaft 50, and the three winding core-equipped winding plates 100 wound with a coil-like strip material are attached to the rotating shaft 50.
Remove more. At this time, a large stress due to the weight of the strip is applied to the core of the winding plate with the core around which the strip is wound and the take-up plate 100. However, here, when the sliding bolt 33 provided on the winding plate 100 in the expanded state shown in FIG. 1 is rotated in the reverse direction to lower the slide fitting 31, the acute-angled portions 22A, 22B, 22C, 22D also start to lower and move. Formula arm 20A, 20B, 20C, 20
D contracts. Outer arc line portion 21 of movable arm 20A
A, an outer arc line portion (not shown) of the movable arm 20B, an outer arc line portion 21C of the movable arm 20C, and an outer arc line portion (not shown) of the movable arm 20D.
Forms an arc smaller than the inner diameter of the winding core, and the winding plate 100 is in the contracted state shown in FIG.

The winding plate 100 in this contracted state
Can be easily detached from the core by applying a slight force. As a result, the time required to remove the winding plate 100 from the winding plate with a core around which the strip was wound could be reduced to one-third that of the conventional case. Moreover, it is not necessary to remove the winding plate 100 by striking the strip, the product is not damaged, and the cause of the accident can be deleted.

In the case where it is not necessary to remove the winding plate from the winding plate with the core around which the strip is wound due to a request for a post process or the like, it is possible to expand and contract as described in this embodiment. Instead of using the winding plate 100, it is also possible to wind a strip or the like using a normal winding plate and the winding device 200 described in the present embodiment.
