Description

Description: FIELD OF THE INVENTION The present invention relates to a wire straightening device for straightening a wire that has been subjected to various treatments such as a plating and cleaning process, and more particularly, to a wire having a straightened shape after coiling. The present invention relates to a wire straightening device suitable for the case.

[Prior art] A wire rod such as a steel wire for forging is subjected to various processes such as a wire drawing process, a plating process, and a washing process, and then formed into a coil shape in a cylindrical container called a cage. Be concentrated. The wire is temporarily stored in the basket, and then re-wound into a smaller coil to form a product coil. However, wires that have undergone various processing steps and processing steps have various so-called habits, and in order to make the wires stick, the wires are collected when the wires are collected in the basket and when the wires are pulled out of the basket. Tangle is easy to occur. Such entanglement of the wire may occur due to the twist of the wire itself. Further, not only in order to avoid such inconvenience in the wire collecting step, but also depending on the use of the wire, it may be required that the wire as a product has as little twist as possible.

FIG. 3 (a) is a schematic diagram showing a conventional wire straightening device, FIG. 3 (b) is a schematic diagram showing a running locus of the wire in the conventional device, and FIG. 3 (c) shows a peripheral surface of a driving roller. It is a schematic diagram. As shown in FIG. 3 (a), the wire 1 runs sequentially with the drive roller 2 wound one turn. In this case, wire 1
Is formed along the peripheral surface of the drive roller 2 as shown in FIG. 3 (b). The peripheral surface of the drive roller 2 around which the wire 1 is wound is formed, for example, in a V-shaped cross section, as shown in FIG. 3 (c).

[Problems to be Solved by the Invention] However, in the above-described conventional wire straightening apparatus, as shown in FIG. 3 (c), the wire 1 has an incoming line position A and an outgoing line position B on the drive roller 2. Since they are inevitably different from each other, the peripheral surface of the drive roller 2 is slid in the axial direction by a distance l while the drive roller 2 is circling. Then, there is a problem that the wire 1 is twisted due to friction between the wire 1 and the drive roller 2. When the wire 1 is twisted, the wire 1 is likely to be entangled when the wire 1 is concentrated in the container and when the wire 1 is pulled out from the container.

The present invention has been made in view of such a problem, and provides a wire straightening device capable of preventing twisting of a wire and correcting a wire after various treatments so as not to be entangled. The purpose is to:

[Means for Solving the Problems] A wire straightening apparatus according to the present invention comprises a driving roller and a driven roller arranged in the same plane with their axial directions parallel to each other; Rollable to linear position and separated from drive roller 1
A pair of auxiliary rollers, and after the wire is wound around the drive roller at the incoming position, wound around the driven roller, and wound again around the drive roller, the outgoing position Is transmitted from the server.

[Operation] In the present invention, the wire is first wound around the first roller, then wound around the second roller, and then wound again around the first roller, and then outgoing to a predetermined concentrator. And so on. In this case, the first roller may be a driving roller, and the second roller may be a driven roller that follows the first roller by running the wire.

Also in the present invention, although the input position and the output position of the wire in the first roller are different from each other in the axial direction of the first roller, the movement of the wire in the axial direction of the roller is the first roller. From the second roller to the first roller through the second roller. For this reason, the wire does not slide on the peripheral surface of the drive roller and the peripheral surface of the driven roller in the width direction, so that the wire can be prevented from being twisted due to friction. This makes it possible to correct the wires after various treatments so that they do not become entangled, and it is possible to perform a smooth wire drawing operation.

In the present invention, it is preferable that the diameter of the driving roller and the diameter of the driven roller are substantially the same, and the copper is rotated at a peripheral speed of copper. Originally, by increasing the diameters of the driving roller and the driven roller to infinity, it is possible to prevent the occurrence of a habit in the wire rod. However, the size of these rollers is limited in terms of equipment. For this reason, it is necessary to set a finite diameter for the drive roller and the driven roller. If the diameters are different from each other, a different habit occurs in the wire rod according to each roller. However,
If the diameter of the driving roller and the diameter of the driven roller are made substantially the same, the habit generated in the wire can be reduced. Thereby, the cast given to the wire in various processing steps can be made even more uniform.

Example Next, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a side view showing a wire straightening apparatus according to an embodiment of the present invention.

The traveling direction of the wire 1 (indicated by a dashed line in FIG. 1) is adjusted horizontally by a turn reel 12 and wound around the drive roller 2. The drive roller 2 has its central axis horizontal, and is rotatable about this central axis. The driving roller 2 is, for example,
It is driven to rotate around its central axis by a 5.5 kW motor (not shown) or the like.

The wire 1 travels horizontally from the turn reel 12 and enters the drive roller 2. Further, the wire 1 exits from the drive roller 2 vertically downward. The peripheral end surface of the driving roller 2 is formed as a V-shaped groove, and the wire 1 is engaged in the V-shaped groove. Auxiliary devices 4 and 5 for guiding the wire 1 are installed at the wire entry position and the exit position of the drive roller 2, respectively. In the auxiliary devices 4 and 5, an L-shaped link is swingably disposed with its bent central portion as a fulcrum, and a rolling roller is rotatably fixed to one end of this link, and Is connected to the piston of the cylinder. And
When the piston advances, the rolling roller contacts the peripheral surface of the driving roller 2 and rolls. As a result, the wire 1 wound around the drive roller 2 becomes
The wire rod 1 is contained in the groove and is prevented from coming off the drive roller 2 during traveling. The wire 1 output from the drive roller 2 is guided by a guide reel 6 installed on a side surface of the support base 3 below the auxiliary device 5 to be collected.

The driven roller 7 is disposed in the same plane as the driving roller 2, and its diameter is substantially the same as the diameter of the driving roller 2. The driven roller 7 has its central axis parallel to the drive roller 2 and is rotatably mounted on the support base 8 around the central axis. On the support 8, correction roller groups 9, 10, 11 are arranged along the running locus of the wire 1 between the drive roller 2 and the turn reel 12. Straightening roller group
In 9 and 11, a plurality of rollers are arranged in a zigzag in a side view, and in the correction roller group 10, a plurality of rollers are arranged in a zigzag in a plan view.
By the wire 1 traveling between the rollers in 9,10,11,
The so-called habit of the wire 1 is corrected.

Next, the operation of the wire straightening device configured as described above will be described. The traveling direction of the wire rod 1 after various processing steps is adjusted horizontally by the turn reel 12 and enters the straightening roller groups 9 to 11, and passes through the straightening roller groups 9 to 11 to correct the so-called habit. Then, it is wound above the drive roller 2. In this case, the wire rod 1 is wound around the drive roller 2 after the pistons of the auxiliary devices 4 and 5 are retracted to separate the rolling rollers from the drive roller 2. Next, after the wire 1 is wound around the driven roller 7, it is wound again around the drive roller 2. Then, the pistons of the auxiliary devices 4 and 5 are advanced to roll the rolling rollers around the driving roller 2. Thereby, the wire 1 is wound around the drive roller 2 so as not to come off. In this way, after the wire 1 is guided by the auxiliary devices 4 and 5 and travels along the peripheral surfaces of the drive roller 2 and the driven roller 7,
It is guided by the guide reel 6 and sent out to the line concentrator.

In this embodiment, since the wire 1 is wound over both the driving roller 2 and the driven roller 7, the traveling locus is formed as shown in FIG. In this case, wire 1
Are different from each other in the axial position between the incoming line position and the outgoing line position with respect to the drive roller 2. However, the wire 1 moves in the axial direction of the driving roller 2 before returning to the driving roller 2 via the driven roller 7. For this reason, since the wire 1 does not slide on the peripheral surfaces of the driving roller 2 and the driven roller 7 in the width direction thereof, it is possible to prevent the wire 1 from being twisted due to friction. Thereby, the wire 1 after various treatments can be corrected so as not to be entangled, and a smooth wire drawing operation can be performed.

Further, in this embodiment, since the diameter of the driving roller 2 and the diameter of the driven roller 7 are substantially the same, there is an advantage that the cast applied to the wire 1 in various processing steps can be made uniform. .

In the driving roller 2 and the driven roller 7, the cross-sectional shape of the peripheral end surface around which the wire 1 is wound is not particularly limited, and may be various shapes such as a U-shape.

[Effects of the Invention] As described above, according to the present invention, the wire is wound around the first roller, then wound around the second roller, and again the first wire.
, The wire rod can be prevented from sliding on the peripheral surfaces of the first and second rollers in the axial direction. Therefore, the wire can be prevented from being twisted due to friction, and the wire after various treatments can be corrected so as not to be entangled. Therefore, according to the present invention, a smooth line drawing operation can be performed.
