Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire material straightening device that can be used for straightening the bends of wire materials such as electric wires and for wrapping a label-shaped mark for displaying a wire attacher.

The ends of the wires are left untreated, and the wires are stripped, crimped, and marked with markings attached.

In order to perform these steps reliably, K requires precision in positioning the supplied electric wire, but since there is a step of cutting the wire to a predetermined length in the previous step, the wire tends to bend slightly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire straightening device that facilitates the straightening of wire wires and contributes to automation of unprocessed wire ends.

The present invention will be explained below with reference to an embodiment shown in the drawings.

In Figure 1, 2 is a base plate, 3 is a block attached to the base 2, 4 is a motor for driving this device, and block 3
attached to.

1 is a mechanical part of the present invention, and a hole 5 into which the linear material to be straightened is inserted.
on the end face.

In FIG. 2, the mechanism part 1 has its shaft part 9
This shaft portion 9 is further connected to the shaft 7 of the motor 4 via a key 8.

Therefore, the rotation of the motor 4 is transmitted to the mechanism section 1.

6a > 6b A bearing of the shaft portion 9, which is provided within the block 3.

3 to 7 show the detailed configuration of the mechanism section 1. FIG.

Reference numeral 12 denotes a rotating body which constitutes the main body of the mechanism section 1, and three shafts 13a, 13b, t13c are screwed to the end face thereof at equiangular angles with respect to the center of rotation.

Also, these shafts 13a, 13b, 13c are dogleg-shaped pieces 16a.
.

It is also the fulcrum axis of 16b and 16c.

As shown in FIG. 5, the doglegged piece 16a has a weight portion 20 on one side.

On the other hand, the roller 14a is inserted into a U-shaped portion 25, and a pin 21a is caulked thereto, so that the roller 14a is rotatably supported between the tips of the U-shaped portion 25.

Of course, the other doglegged pieces 16 b t 16 c have the same structure, and the suffixes b and c are added to the related symbols, and the explanation thereof will be omitted.

In addition, pins 19a, 19b, 19c are inserted into the bent parts of these doglegged pieces 16a, 16b, 16c, respectively.
and their opposite ends, as shown in FIG.
6 a , 16 b t 16 c protrude by a predetermined length from the surface.

17 digit dog-shaped pieces 16 a, 16 b t 16
A ring for interlocking and rotating the rotating body 12
It is inserted into an annular groove 22 formed on the end face with a suitable clearance so as to be able to slide easily, and a pair of protrusions 18a and 1ab are provided on one face thereof at an interval of 180°.

Furthermore, as already shown in FIG. 3, a pair of receivers U 23 a and 23 b are provided in the groove 22 at an interval of 180°, and are integrally formed with the rotating body 12 .

Repulsion springs 15a and 15b are disposed within the groove 22 so that one end thereof is in contact with one side of the corresponding seat 23a and 23b.

Therefore, when the ring 17 is installed in the groove 22, the third
As shown by broken lines in figure a, the protrusions 18a, 1s
b comes into contact with the other ends of the corresponding rebound springs 15a and 1sb.

That is, the protrusion 18a. 18b protrudes to the right in the figure when installed in the groove 22, as shown in FIG. 4, and receives the end of the repulsion spring (not shown).

Therefore, the ring 17 is a repulsion spring 15a. 15b constantly receives an acting force in the clockwise direction in FIG. 3a.

Further, on the surface of the ring 17 opposite to the protrusions 18a and 18b, there are three locking grooves 28 as shown in FIG.
a t 28 b t 28 c are provided at equal intervals.

These locking grooves 28a and 28b. 28c is ring 17
When mounted in the groove 22, the dogleg-shaped piece 16a as shown by the broken line in FIG. 3a.

Pin 19a driven into 16bt16c > 19b
? It engages with the protruding end of 19c as shown in FIG.

Therefore, the doglegged pieces 16a, 16b, 16c are connected to the ring 1.
7 (due to the acting force of the compression springs 15a, 15b), the fulcrum shafts 13a, 13b move in conjunction with each other.
, 13c.

A hole 24 is formed in the center of the rotating body 12, and this is an escape hole for inserting the straightened wire material.

In addition, the lid 11 that covers the end face of the rotating body 12 has a swing shaft 13a.
Screw 10a screwed into the head of t 13b t 13c
, 10b, 10c.

Next, the straightening process of the wire material will be explained with reference to FIGS. 9 to 11.

In FIG. 9, the straightened wire material 26 is inserted in the direction of the arrow.

At this time, the mechanism section 1 is stopped.

After insertion, when the motor 4 is operated to rotate the mechanism part 1,
The doglegged pieces 16a t 16b t 16c are activated by the centrifugal force of the harpoon section 20 to generate the repulsive spring 15a.

15b in the direction shown by arrow A in FIG. 3a.

This rotational force is mutually transmitted through the ring 17 and rotates the ring 17 until the rollers 14 a t 14 b t 14 c grip the filament with sufficient force.

FIG. 8 shows the state at this time.
4b and 14c rotate with the filament 2'6 at the center.

In this state, when the wire material 26 is then pulled in the direction of the rotating shaft as shown in FIG. 10, the wire material 26 continues to rotate as shown in FIG.

Since it passes between 14b and 14c, it is straightened into a straight line and pulled out.

If the motor 4 is equipped with a brake or a brake mechanism is provided, the correction work can be performed more efficiently.

Note that the device of the present invention is capable of not only correcting the filament 26 but also correcting the 12th
It can also be used to wrap a wire display label mark 27 around a wire material, for example, an electric wire 26, as shown in FIGS.

That is, in the state shown in FIG. 12, if the mechanism section 1 is rotated after being inserted into the hole 5 of the mechanism section 1, the roller 1 will be removed as in the case of straightening.
4a.

Since 14b and 14c rotate while pressing around the filament 26, the label-shaped mark 27 can be applied evenly and uniformly by this pressing force.

Therefore, after the mechanism part 1 is stopped after winding is completed, when the wire material 26 is taken out, it will be as shown in FIG. 13.

As explained above, the present invention aims to straighten the bend of the wire by simply rotating the mechanism after inserting the wire into the mechanism, thereby eliminating the need for the conventional troublesome work of straightening the bend. I can do it.

Therefore, it is easy to straighten the bend after cutting the wire when processing the end of the wire, and it is also possible to wrap marks etc.
By automatically operating the wire or the proposed device, it can greatly contribute to the automation of untreated wire ends.
