Description

[Detailed description of the invention] The present invention relates to a winding machine for winding up long objects such as steel wires, which makes the winding pattern uniform and can wind up heavy bundles with a simple configuration. The feature is that it is configured as follows.

Conventionally, there are various types of winding machines for long objects such as steel wire, but they can be classified into three types: take-up, trade-in, and take-over methods.

The top-up method involves applying a constant tension to the long body, introducing the long body from the bottom of the winding machine that rotates at a constant speed, winding it up into the rotating tube, and sequentially rolling the long body to the lower part. This method involves pushing it upwards and rolling it up into a bundle. FIG. 1 shows a winding machine that adopts this take-up method. Specifically, the elongated body 01 is equipped with a straightening roller 0 for suppressing vibration and curling of the elongated body 01.
2, it is introduced into the lowest part of the rotary cylinder 03 rotating at the upper part of the machine head 05 via a transmission shaft 06 that transmits the rotation from the motor, where it is rolled up and turned into a long body. 01 is successively pushed upward like 02', forming a bundle. In the figure, reference numeral 04 denotes a holding rod that prevents the rolled-up elongated body 01 from flying out from the rotary cylinder 03.

Next, the trade-in method is a configuration in which the above-mentioned top-up method is reversed, and a carrier for wire storage is arranged further below. In detail, as shown in FIG. It is introduced into the uppermost part of the rotating cylindrical body 03 facing downward via the rollers 02. Cylindrical body 0
3, a transmission shaft 07 receives rotation from a motor and rotates via a bearing attached to a fixed frame 06. Therefore, the elongated body introduced into the cylindrical body 03 is wrapped around the cylindrical body 03 at least several times and then sequentially pushed downward. The pushed down elongated body 01 includes a base 09 that rotates in the same direction and at the same speed in synchronization with the cylindrical body 03 installed directly below the cylindrical body 03, and a carrier 08 that is detachably attached to the base 09. 0 guide rods on top
4 and then rolled up into a bundle around the carrier shaft 05 as shown in 2'.

As mentioned above, in conventional winding machines, in both the top-up and trade-in methods, the long body is pushed upward or dropped by the natural action of the long body that is rolled up once. Therefore, such push-up and fall conditions are not always the same, and several loops may pop out due to rotation. For this reason, the rolled-up elongated body has different curls in some parts, which poses a problem in terms of quality control. Furthermore, since the degree of curling described above becomes more pronounced as the amount of storage increases, there is a drawback that the size (weight) of the bundle cannot be increased too much. Furthermore, in the trade-in system, base 09, carrier 08 and this base 0
9 and carrier 08 are required to synchronize with the cylindrical body 03 and rotate in the same direction in the same direction, a device and control are required, which has the disadvantage that the structure of the winding machine becomes larger and more complicated. In addition, in the case of the horizontal pickup method, the storage of the elongated body is biased towards the tip of the cylindrical body, and the bending stress at the tip of the conduction shaft becomes large, causing the bundle to collapse in this case as well. There is a limit to the size (weight) of the loop, and there is also the disadvantage that the loop may pop out when rotated.

The present invention has been proposed in view of the above-mentioned points, and consists of a rotating cylindrical body rotated by a motor, and a part of the rotating cylindrical body attached to a part of the rotating cylindrical body in a trade-in type winding machine. a reflecting plate, a saucer slidably attached to a slide rod extending downward from the rotating cylinder, a rack rod for lowering the tray, and a slide motor for operating the rack rod. , a phototube that emits a luminous flux toward the reflector, and an electric circuit that senses the reflection state of the luminous flux emitted from the phototube on the reflector and sends a rotation or stop signal to the slide motor based on the sensing signal. With this structure, it is possible to prevent the elongated body from being unevenly curled and to obtain a large-weight rolled bundle, and further,
The feature is that the structure of the winding machine is downsized and simplified.

Below, an embodiment of the present invention will be described based on the attached FIG. 3. 1 is a fixed frame, 2 is a rotating cylindrical body supported by this fixed frame 1, and rotated by a motor (not shown) via a rotating shaft 3. be. Reference numeral 4 designates a plurality of slide rods protruding from the rotating cylindrical body 2, and these slide rods are arranged on a circumferential line having the same center point as the center of the rotating cylindrical body 2. Reference numeral 5 denotes a saucer that is slidably attached to the slide rod 4, and 6 is a rack rod whose lower end is connected to the center of the saucer 5 through the center of the rotating shaft 3 and the rotating cylindrical body 3. The pin-on gear 8 attached to the rotating shaft 7' of the slide motor 7 is engaged with the pin-on gear 8.

9 is the lower surface of the fixed frame 1, and is a phototube attached toward the rotating cylinder 3; 10 is the outer surface of the rotating cylinder 3, and is a reflecting plate attached at a position corresponding to the phototube 9. Note that this reflecting plate 10 may be replaced with a light receiving plate.

Reference numeral 11 indicates that the light beam emitted by the phototube 9 is reflected on the reflector plate 1.
0 and receives the reflected light, or the light receiving plate receives the light beam emitted from the phototube 9, and sends a rotation stop signal to the slide motor 7, and when the light beam is not received, the slide motor 7 This is an electric circuit that sends a rotation signal to the motor 7.

12 is a correction roller, 13 is a guide roller,
a indicates a long body.

The winding machine according to the present invention has the above-mentioned configuration, and the elongated body a passes through the straightening roller 12 to adjust its curl, and then is introduced into the top of the rotating cylindrical body 2, and is passed through the rotating cylindrical body 2 multiple times. It is rolled up and sent out via the guide roller 13 to the lower side of the elongated body upper and lower separating collar 2'.

A long body a sent out to the lower side of the upper and lower separating collar 2'
are stored in a bundle on the tray 5 as shown in a'. At this time, when the light beam emitted from the phototube 9 is reflected by the reflecting plate 10 and the reflected light is received, or when the light receiving plate attached to the rotating cylinder 2 is receiving the light as in the other embodiment,
An electric circuit 11 issues a stop signal to the slide motor 7, and the saucer 5 rotates together with the rotating cylinder 2 on the slide rod 4. but,
When the amount of the elongated body a increases and it wraps around the rotating cylindrical body 2 and completely covers the reflecting plate 10 (light receiving plate), the light beam emitted from the phototube 9 is not received, so the electric circuit 11 is slide motor 7
Sends a rotation signal to. In response to this rotation signal, the slide motor 7 rotates and slides the rack rod 6 downward via the pin-on gear 8. Since the rack bar 6 is connected to the saucer 5 at its lower end, the saucer 5 slides downward along the slide bar 4. When the tray 5 slides downward, the stored elongate body a also moves together. As a result of this movement, the reflector plate 10 is exposed again, so it begins to receive the light beam from the phototube 9 again, and the electric circuit 11 sends a stop signal to the slide motor 7, causing the rack bar 6 and saucer plate 5 to descend. Stop and continue winding.

According to the present invention, the elongated body a is rolled up and stored while automatically lowering the tray 5 through the above-described operation. By the way, when the rotating cylindrical body 2 is long and the slide rod 4 is not used, the elongated body a is in line contact on the rotating cylindrical body 2 for a long time, and furthermore, due to the thermal influence of wire drawing etc., the elongated body a and The rotating cylindrical body 2 thermally expands and clings to the rotating cylindrical body 2, making it difficult to slide downward. However, the rotary cylindrical body 2 is cut to an appropriate length, and the tip is attached to the saucer 5 using the slide rod 4.
By reaching this point, the elongated body a and the slide rod 4 come into point contact and are less susceptible to thermal effects, and as a result, the elongated body a descends while sliding smoothly.

The winding machine according to the present invention has the structure and operation as described above, and its effects are listed below.

Elongated body a introduced into the top of the rotating cylindrical body 2
is always rolled up under the same conditions as the tray 5 descends, so there is no need to worry about uneven curls forming on the elongated body a.

Separate the saucer 5 and the rotating cylindrical body 2, and remove the saucer 5.
Since the storage is automatically lowered by the action of the phototube 9 and the reflecting plate 10 (or light receiving plate) attached to the rotating cylinder 2, the storage amount is stable and can be increased by lengthening the slide rod 4. It is possible to roll up heavy (large bundles).

Separate the rotating cylindrical body 2 and the saucer 5, and remove the saucer 5.
When the slide rod 4 descends, the slide rod 4 bridges this gap, so that the rolled-up elongated body a comes into point contact with the slide rod 4 at the intermediate portion and smoothly slides onto the tray 5.

While adopting the trade-in system, the winding machine can be downsized and simplified because it does not require a base, a carrier, a rotation synchronization mechanism, etc. as in the conventional case.
