FIELD OF THE INVENTION The present invention relates to a spinning bobbin having an identification marker.

[0002]

2. Description of the Related Art Generally, there are many brands of spun yarns and the like. Therefore, it is necessary to make it possible for each spun bobbin wound with spun yarns of different brands to be identified for each brand. The bobbin is provided with an identification marker according to the brand.

On the other hand, in order to increase the operating efficiency of a single textile machine due to the tendency of high-mix, low-volume production, spun yarns of different brands for a plurality of sections are spun and wound on a spinning bobbin. As a result, it is necessary to automatically supply a spinning bobbin with a plurality of types of identification markers according to the type of spun yarn to each section.

In the automatic supply of the spinning bobbin with the identification marker or the like, in order to identify and classify the spinning bobbin, colored paper is attached to the spinning bobbin as an identification marker according to the brand, for example, the spinning bobbin is attached. A means for discriminating a so-called color sensor that projects a laser beam on a colored paper and receives the reflected light is used.

[0005]

In the spinning bobbin on which colored papers of different colors are pasted as the identification markers, a slight color difference is likely to cause malfunction in the identification by the color sensor, so that the number of colors that can be used is limited. Few. In addition, the number of brands is gradually increasing, and accordingly, it has become necessary to use the similar color for the identification marker of the spinning bobbin, which naturally causes erroneous identification and mixes different brands. .

A spinning bobbin having the above-mentioned identification marker,
For example, in a spun bobbin 5 having a colored paper 4 attached to the top as shown in FIG. 6, when the spun yarn 6 is fed from the spun bobbin 5, the spun yarn 6 on the inner layer side rubs against the edge of the colored paper 4. While spun out, the spun yarn is colored,
There was a problem of product failure. Further, the spinning bobbin is repeatedly used many times, and in the course of its distribution, there is a problem that the colored paper, which is an identification marker, becomes dirty, the color is faded, and the colored paper falls off.

In consideration of the above conventional problems, the present invention enables reliable identification without using colored paper as an identification marker,
Another object of the present invention is to provide a spun bobbin in which no color adheres to the spun yarn and which can be repeatedly used.

[0008]

According to the present invention, in order to solve the above problems, an amorphous magnetic metal thin wire is provided as an identification element by an identification sensor on the upper part of a bobbin main body made of a non-magnetic material such as synthetic resin. A plurality of the amorphous magnetic metal thin wires are used, each having a different magnetization reversal magnetic field value, substantially parallel to the length direction of the bobbin main body, and
A spun bobbin is configured by selecting and arranging the arrangement order according to the type of spun yarn.

FUNCTION The amorphous magnetic metal has a square hysteresis curve in its characteristic, and the S pole and N pole have the property of reversing in a short time by applying a magnetic field from the outside due to this characteristic. Therefore, if a detection coil is provided as a sensor, a pulsed induced voltage can be obtained in the detection coil when the magnetic pole is reversed. Since the pulse of the induced voltage is sharp in the amorphous magnetic metal, it is convenient to extract it as a pulse signal. Utilizing these properties, the spinning bobbin of the present invention is provided with a plurality of amorphous magnetic metal thin wires having different magnetization reversal magnetic field values as identification elements.

The identification is performed by an identification sensor. The identification sensor generates an alternating current with an alternating current oscillator and supplies it to an exciting coil to generate an alternating magnetic field. With this alternating magnetic field, the detection coil detects changes in magnetic flux due to magnetic pole reversal of a plurality of amorphous magnetic metal thin wires in the spinning bobbin as a pulsed induced voltage, and the pulsed induced voltage is converted into a bit string by a measuring instrument.

More specifically, as shown in FIG. 4, the alternating magnetic field is applied so as to gradually increase with time. In response to this, the amorphous magnetic metal thin wire H _{C1 at} the first position first undergoes magnetic pole reversal to obtain a pulsed induced voltage. Then, after a small time delay, the magnetic pole of the amorphous magnetic metal thin wire H _C2 located at the second position and having a slightly larger magnetization reversal magnetic field value is pole-reversed, and the second pulsed induced voltage is obtained.
In this way, the amorphous magnetic metal thin wires H _C6 having the largest magnetization reversal magnetic field value, which are sequentially located at the sixth position, undergo magnetic pole reversal to obtain the sixth pulsed induced voltage. The bit is "1" due to the presence of one amorphous magnetic metal thin wire,
The bit is "0" at the position where the amorphous magnetic metal thin wire is omitted. In this way, bit determination is performed.
In this case, the bit string is 111111.

[0012] The number of the amorphous metal thin wires is determined according to the type of identification and classification. For example, when N amorphous magnetic metal thin wires having different magnetization reversal magnetic field values are used, if one is used as a pulse at the reference position. The pulse train extracted in combination with this, that is, the number of types that can be identified is 2 (N-1). Note that the combination means the arrangement of only one reference amorphous magnetic metal thin wire, one reference amorphous magnetic metal thin wire and one arrangement of each amorphous magnetic metal thin wire, and one reference amorphous magnetic metal thin wire and two. A type of amorphous magnetic metal wiring, a combination of one reference amorphous magnetic metal thin wire and all other amorphous magnetic metal thin wires. In this way, for example, by adding and removing six amorphous magnetic metal fine wires, a bit string of 2 to the fifth power, that is, 32 bit strings shown in FIG. 5 can be obtained, and thus 32 kinds of spinning bobbins can be identified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a bobbin main body made of synthetic resin, and has a recess 2 at the top thereof. The recess 2
An identification marker 3 configured as a chip is embedded in the chip. As shown in FIGS. 2 and 3, the identification marker 3 is a cylindrical chip 3 made of a non-magnetic material such as synthetic resin.
Amorphous magnetic metal thin wires H _C6 are attached to the outer peripheral surface of a so as to be perpendicular to the bottom surface of the chip 3a, and the amorphous magnetic metal thin wires H _{C1 to} H _C5 are parallel to the amorphous magnetic metal thin wires H _{C6 at} equal intervals. It is configured by mounting.

The amorphous magnetic metal thin wires H _{C1 to} H _C6
Has a length of 10 to 25 mm and a diameter of 0.02 to 0.05 mm, and has different magnetic pole reversal values. In this example, the amorphous magnetic metal thin wire is made of iron and cobalt as main composition materials, and silicon and boron added thereto.
Then, the magnetization reversal magnetic field value is different depending on the heating temperature and the tension change during manufacturing.

Since six amorphous magnetic metal thin wires having different magnetization reversal magnetic field values are used in this embodiment, if one amorphous magnetic metal thin wire H _C6 is used as the pulse at the reference position, it can be discriminated. The number is 2 to the 5th power, that is 32
It becomes a kind.

According to the present embodiment, in this way, many brands of spun bobbins can be positively identified by the identification sensor, an identification error does not occur, and a color may be attached to the spun yarn. Absent.

In the above embodiment, the length of the amorphous magnetic metal thin wire is 10 to 25 mm and the diameter is 0.02 to 0.05 mm.
However, if the length is 10 mm or less, it becomes difficult to detect the pulse, and it becomes difficult to apply an external magnetic field that is uniform in the length direction. When the diameter is larger than 0.05 mm, the length cannot be shortened to a certain value or less due to the influence of the demagnetizing field. Therefore, the preferable range of the length and diameter of the amorphous magnetic metal thin wire is naturally determined.

Although the number of the amorphous magnetic metal thin wires is six in the embodiment, the number may be increased or decreased depending on the kind of spun yarn.
The amorphous magnetic metal thin wire may be embedded in the outer periphery of the spinning bobbin itself, instead of being provided on the chip.

According to the present invention, a plurality of amorphous magnetic metal thin wires each having a different magnetization reversal magnetic field value are provided on the upper portion of the bobbin main body, in parallel with the length direction of the bobbin main body, and in accordance with the kind of spun yarn. Since the spinning bobbin is configured by selecting the arrangement order, the pulse train of the pulse-shaped induced voltage generated in the identification sensor when a magnetic field is applied by the identification sensor,
The type of spinning bobbin can be identified with certainty. Since the arrangement of the amorphous magnetic metal thin wires can be changed in various ways, it is possible to create a spinning bobbin having various kinds of identification elements. Further, when the spun yarn is paid out, the spun yarn is not colored, and the spun yarn can sufficiently withstand repeated use. Further, it is useful as a spinning bobbin for automatic distinctive mounting when supplying to a textile machine such as an automatic winder.
