Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rosette pattern winding device used for winding a wire drawn by a wire drawing machine into a rosette pattern.

Generally, the wire drawn by a wire drawing machine is sent to the next process to prevent it from getting tangled.
It has become common for people to follow a pattern.

Conventionally, there have been various methods for winding in a rosette pattern, but the conventional structure did not allow for sufficient winding volume, and it was technically difficult to wind at high speed. It had various drawbacks, such as poor efficiency and difficulty in applying it to high-speed winding machines such as wire drawing machines.

The present invention was devised in view of the above points, and by using a uniquely shaped presser roll, the pattern density of the rosette pattern is made denser, the bulk of the roll is reduced, and the amount of roll is increased. The purpose of this is to increase the efficiency of winding and to perform high-speed winding.

The configuration of the present invention is that a carrier for regulating the inner diameter of the coil is erected and fixed on the upper part of the turntable, and outer frame rolls that regulate the outer diameter of the coil and can rotate are arranged at multiple locations around the turntable. , a roll shaft is provided through a bracket to an outer cylinder that can be raised and lowered along the outer frame roll, a presser roll is rotatably fitted on the roll shaft, and the presser roll is held horizontally and at the center of the carrier. At the same time, the length of the presser roll is set to be equal to or longer than the distance between the inner and outer diameters of the coil of the pattern roll, and a tapered part for drawing the wire is formed at the tip of the presser roll. On the other hand, a guide rod for guiding the wire to the tip of the presser roll is fixed to the outer cylinder or bracket, and a wire guide fixed to a dead block type wire drawing machine drum is faced above the carrier. The inclination of the turntable is set to such an extent that the wire falls naturally, while the direction of rotation of the turntable is set so that the coil diameter is increased.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 is a schematic side view showing an embodiment of the wire rosette pattern winding device according to the present invention. It is interlocked and connected to the output rotation shaft 3 of the drive source 2 consisting of
The direction of rotation is set so that the coil diameter, which will be described later, rotates in a direction that increases. Further, the rotation speed of the turntable 1 is set to about 2 times/minute.

A coil 4 is mounted on the top of the turntable 1.
(See FIG. 5) A carrier 5 which regulates the inner diameter of the rosette pattern winding, more specifically, the inner diameter of the coil, is fixed in place.

As shown in FIG. 2, this carrier 5 includes an inner ring 5a and an outer ring 5 that are directly fixed on the turntable 1.

Outer frame rolls 6 for regulating the outer diameter of the coil are vertically disposed at four locations around the turntable 1. Each of these outer frame rolls 6... is loosely fitted into a vertical shaft 7... as shown in FIG.
It has a rotatable structure that rotates naturally due to the contact of the coil 4.

As shown in FIGS. 1 and 2, outer cylinders 8, 8 which can be raised and lowered along the outer frame roll 6 are loosely fitted into one of the four outer frame rolls 6. A bracket 9 is fixed to each of the upper and lower outer cylinders 8, 8, and a roll shaft 10 is attached to the bracket 9.

As shown in FIG. 3, a presser roll 13 is fitted onto this roll shaft 10 via bearings 11 and 12 so as to be freely rotatable. As shown in FIG.
The roll axes of the rollers are arranged horizontally as shown in FIG.

Further, as is clear from FIG. 5, the total length of the presser roll 13 is set to be equal to or longer than the distance between the inner and outer diameters of the pattern-wound coil, and the tip of the presser roll 13 is set as shown in FIG. As clearly shown in FIG.

Here, the presser roll 13 is made of iron and weighs approximately 10 kg (when used for winding wire with a diameter of 1.6 to 3 mm), and the dimensions of each part in Fig. 3 are as follows. be.

a=190, b=115, c=75, d=15, e=125〓, f=80〓, g=55〓 (unit: millimeters), θ≒20゜ On the other hand, the bracket 9 is the outer frame roll As shown in FIG. 2, a roller 16 is rotatably mounted on a bracket 9 to prevent free rotation around the roller 6 through a rod 14 and a portal plate 15. It is located in the groove of the support column 17 which has a groove continuous in the vertical direction.

Further, a guide rod 18 is fixed to the outer cylinders 8, 8 as shown in FIG. This guide rod 18 is for guiding the wire falling from the wire drawing machine drum 19 via the wire guide 20 toward the carrier 5 to the tip of the presser roll 13.

Furthermore, the tip of a wire guide 20 fixed to a wire drawing machine drum 19 of a dead block type is exposed above the carrier 5, and the wire guide 20 has a sloped surface 20a that allows the wire to fall naturally. are doing. In this embodiment, the angle of the inclined surface 20a is set to about 25 degrees.

Here, the wire guide 20 is fixed,
On the other hand, since the carrier 5 rotates together with the turntable 1, the connection structure between these two 5 and 20 is as shown in FIG.

That is, the shaft body 21 is attached to the lower surface of the wire guide 20.

and the rotating plate 22 are connected by rods 24...

Next, a specific support structure for the outer frame roll 6 will be described with reference to FIG.

7... are fitted rotatably, and an outer frame roll holder 29 on one side is connected to each of these cylinders 27 through a span 28, and a cylinder 31 is connected to the base column 25 through a collar 30. ... are fitted in a rotatable manner, and the outer frame roll holder 33 on the other side is connected to each of these cylindrical bodies 31 through a span 32.

Then, the above-mentioned vertical shaft 7 was attached between the holding tongues 34, 34 provided at both upper and lower ends of the outer frame roll holders 29, 33, and the outer frame roll 6 was loosely fitted on the outer periphery of the shaft 7. The position of the outer frame roll 6 can be adjusted and fixed in the front and rear directions by an adjusting mechanism (not shown).

The illustrated embodiment is configured as described above,
The action will be explained below.

Now, in order to wind the wire drawn by the wire drawing machine into a rosette pattern, the driving source 2 is used.
is energized and rotates the turntable 1 and carrier 5 via its output rotating shaft 3 (approximately 2 times/min)
let The direction of rotation is such that the coil diameter increases.

The drawn wire fed out from the wire drawing machine drum 19 naturally falls one by one due to the slope of the wire guide 20.

Moreover, the wire is guided to the tip of the presser roll 13 by the guide rod 18.

In this way, the wire that falls onto the turntable 1 with its inner diameter part fitted into the carrier 5 is pulled in by the tapered part 13a of the presser roll 13 and is moved in the outer peripheral direction where the peripheral speed is faster due to the difference in peripheral speed. being pulled to.

As the turntable 1 rotates, the above-mentioned action is repeated, and the coil 4 is pulled by the presser roll 13 in the outer circumferential direction where the circumferential speed is high by the tapered portion 13a as shown in FIG.
Due to the non-tapered flat part of the presser roll 13 (the part shown by b in FIG. 3), the presser roll 1
Since it is leveled by its own weight, a high-density lowset pattern as shown in FIG. 5 can be obtained.

At this time, the presser roll 13 naturally rotates around the roll shaft 10, and the outer diameter of the rosette-shaped coil 4 is shaped by the outer frame roll 6 that rotates in contact with the coil. It is.

By repeating this action, the coils 4 in a low set pattern are stacked one after another.
Since the stacked coils are pressed down by the presser roll 13, the amount of patterned coils can be increased and the bulk of the coils can be reduced.

Further, as the coils 4 in the row set pattern are stacked one after another, the presser roll 13 moves upward one after another, and the outer cylinders 8, 8 are loosely fitted into the outer frame roll 6 which contacts the coils and rotates on its own axis. Therefore, the increase will be smooth.

In addition to the above embodiment, the presser roll 13
A so-called weight may be added to the part of the roll shaft 10, and the coil 4 may be pressurized by the weight of the presser roll 13 and the weight of the weight, and the pressing force can be adjusted by varying the mass of the weight. Of course, it may be configured.

As described in detail above, in the present invention, the carrier 5 that regulates the inner diameter of the coil is erected and fixed on the upper part of the turntable 1, and the outer diameter of the coil is controlled at multiple locations around the turntable 1 and the outer diameter is rotatable. While a frame roll 6 is provided, a roll shaft 10 is provided via a bracket 9 to an outer cylinder 8 that can be raised and lowered along the outer frame roll 6, and a presser roll 13 is rotatably fitted onto the roll shaft 10. The presser roll 13 is arranged horizontally and directed toward the center of the carrier 5, and the length of the presser roll 13 is set to be equal to or longer than the distance between the inner and outer diameters of the coil of the pattern roll, and A tapered part 13a is formed at the tip of the presser roll 13 for drawing the wire into it, while a guide rod 18 for guiding the wire to the tip of the presser roll 13 is fixed to the outer tube 8 or the bracket 9. A wire guide 20 fixed to a dead block type wire drawing machine drum 19 faces above the carrier 5.
The inclination gradient of 0 is set to such an extent that the wire naturally falls, while the rotation direction of the turntable 1 is set so that the coil diameter increases, so the pattern density of the rosette pattern is Therefore, it is possible to reduce the volume of the winding and increase the winding volume, improve the winding efficiency, and increase the speed of winding (700 m /
min).

Incidentally, the conventional method that did not use a presser roll had a roll volume of about 1 ton, but the product of the present invention was able to roll a volume of 2 tons.
