SUMMARY OF THE INVENTION As described above, the hose 3
A length mark 20 is printed on the surface of one hose body 2. For this reason, the mark 20 may be hidden by the stain on the surface of the hose 31, or the mark 20 may be erased by friction when the hose is sent out from the reel 17. Thus, when the mark 20 disappears or disappears, the optical sensor 21 cannot detect the mark 20. Also, since the hose 31 has a circular cross section, it is easily twisted,
The position of the mark 20 may be shifted from the optical sensor 21. If the mark 20 is shifted, the optical sensor 21 cannot detect it. Furthermore, the optical sensor is susceptible to light entering from outside the sensor, ribs, stripes, and colors on the surface of the hose, and these may be mistaken for the mark 20. For this reason, the conventional device has a problem that the reliability of detecting the length information of the hose is low. An object of the present invention is to increase the reliability of detecting length information attached to a hose.

[0005]

A hose with length information according to the present invention is characterized in that magnetic hoses are provided with magnetic marks made of magnetic metal at predetermined intervals in the longitudinal direction of the hose body. Since a metal mark made of a magnetic metal can be detected by a metal sensor without using an optical sensor that is often misidentified, the reliability of length information detection is improved. The second invention is characterized in that a metal mark is embedded inside the hose body. Since the metal mark does not appear on the hose surface, there is no fear of the metal mark falling off. A third invention is characterized in that the metal mark is made of ink containing magnetic metal fine powder. In the hose with length information according to the fourth invention, the hose body is composed of a plurality of layers, a reinforcing thread is interposed between any of the layers, and a metal mark made of a metal wire or a metal foil is wound around the reinforcing thread in a coil shape. It is characterized by the following. Since the reinforcing wire is wound in a coil shape, the metal wire or metal foil does not impair the flexibility and elongation of the hose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment shown in FIGS.
It is an example in which the hose 1 with length information is measured by the hose measuring device of FIG. FIG. 1 shows a hose measuring device similar to the hose measuring device of FIG. 9 used in the conventional example. However, reel 1
7, the hose 1 of the present invention is wound. Hose 1
Has a metal mark 3 made of a magnetic metal on the hose body 2 for each unit length L. Then, a metal sensor 11 is installed instead of the optical sensor 21 of the conventional example, and the metal sensor 11 detects the metal mark 3. The same components as those in FIG. 9 are denoted by the same reference numerals. As shown in FIG. 2, the metal sensor 11 includes a ring-shaped detection unit 11a through which the hose 1 passes. This detector 11
A magnetic field is formed in a, and a change in the magnetic field caused by the metal mark 3 passing through the magnetic field is detected as the passage of the metal mark 3. Since the entire circumference of the hose 1 is surrounded as shown in FIG.
No matter where the metal mark 3 passes through 1a, the magnetic field is disturbed and the passage of the metal mark 3 can be detected.

Therefore, the metal mark 3 can be detected no matter where the metal mark 3 is attached in the circumferential direction of the hose body 2. Further, even if the hose is twisted and the position of the metal mark 3 is displaced, it is possible to detect the presence or absence thereof. As shown in FIG. 3, the hose 1 is a multi-layer hose, and the hose body 2 includes an inner layer 4 and an outer layer 5 made of resin and a reinforcing layer 6 therebetween. The reinforcing layer 6 is formed by assembling a polyester reinforcing thread 7. A metal mark 3 is formed by winding a metal wire 8 in a coil shape at a unit length L interval around one warp thread 7a extending in the length direction of the hose body 2 of the reinforcing thread 7. Actually, the reinforcing layer 6 is formed by preparing warp yarns 7a in which metal wires 8 are wound at predetermined intervals in advance.

The reel 17 around which the hose 1 provided with the metal mark 3 is wound on the hose body 2 is set as shown in FIG.
The operation of the hose measuring device will be described. First, when a desired length is input to the data processing unit 15 and the device is turned on, the motor m of the hose feeding unit 13 is operated, and the hose 1 is automatically fed. When the hose 1 is sent out, the metal sensor 11 operates at the same time. Metal sensor 11
When detecting the metal mark 3 on the hose 1, the data signal is transmitted to the data processing unit 15. Data processing unit 15
Then, the number of metal marks 3 is counted, the length of the hose that has been sent out is calculated, and the calculated value is compared with the initially input desired length. As a result, when it is determined that the hose 1 has been fed by the desired length, a command is sent to the controller 14 to stop the motor m and cut the hose 1 at that position.

At this time, the display section 16 displays the hose length at that time. If the total length and unit price of the hose 1 wound on the reel 17 are first stored in the data processing unit 15, the data processing unit 15 can calculate and display the remaining amount of the hose 1 and the sales amount. it can. Instead of the metal wire 8, a tape-shaped metal foil may be wound around the warp 7a to form the metal mark 3. Since such a metal mark 3 is formed by winding a metal wire 8 or a metal foil around a warp 7a in a coil shape, elasticity is maintained. Therefore,
The metal mark 3 does not hinder the hose 1 from bending or pulling. In addition, since the coil-shaped metal wire 8 and the metal foil easily follow the bending of the hose 1, even if the hose 1 is bent, it does not break. In addition, metal mark 3
Is covered with the outer layer 5, so that the metal wire 8 is cut,
It does not rust and is not removed from the hose body 2.

The second embodiment shown in FIG. 5 differs from the first embodiment in that a metal piece 9 is buried in the inside of the hose body 2 to form a metal mark. The metal pieces 9 are embedded at predetermined intervals L in the length direction of the hose body 2. In the metal sensor 11 of the apparatus shown in FIG. 1, no matter where the metal mark 3 passes through the detection section 11 a, the magnetic field is disturbed, so that the metal mark 3 is attached to any part of the hose body 2. , Can be detected by passing through the detection unit 11a. Therefore, the position where the metal piece 9 is embedded is the position of the hose body 2.
Regarding the circumferential direction, any position may be used.

In the third embodiment shown in FIG. 6, a metal mark is formed by arranging a metal foil 10 in a ring shape between layers of a hose body 2 comprising an inner layer 4 and an outer layer 5. This metal foil 10
Also, a foil piece may be used instead of a ring shape. If the outer layer 5 is made transparent so that the metal foil 10 can be seen from the outside of the hose 1, the length of the cut hose can be used as a standard. In this case, if the metal foil 10 forming the metal mark 3 is ring-shaped, the metal mark 3 becomes easier to see than a small foil piece.

The fourth embodiment shown in FIGS.
Is formed with the metal ink 18. Hose body 2
Is composed of an inner layer 4 and an outer layer 5, and the metal ink 18 is an ink containing fine powder of a magnetic metal. Printing is performed on the surface of the inner layer 4 using the metal ink 18 to form the metal marks 3 at intervals L. Of course, the metal mark 3 may be printed on the surface of the outer layer 5, but the metal mark 3 may be printed on the surface of the inner layer 4 as in the fourth embodiment.
There is no worry about disappearing. The operation is the same as that of the other embodiments, but if the metal ink 18 is used, various shapes can be easily formed by printing. Not only as the metal mark 3 detected by the metal sensor 11 but also at the same time, a product type, a product name, and the like can be displayed. However, when printing is performed on the inner layer 4 as in this embodiment, the outer layer 5 must be transparent so that the print can be seen from the outside.

Further, the metal mark 3 can be set only by applying the metal ink 18 to the hose body 2.
The installation of the metal mark 3 is simple. The hose 1 as in the above embodiment has the metal mark 3 on the hose body 2. For this reason, the metal mark 3 can be detected by using the highly reliable metal sensor 11 instead of the optical sensor which is easily affected by external factors and is often misidentified. The metal sensor 11 can detect the metal mark 3 even if the metal mark 3 is not visible from the outside or the hose 1 is twisted, as long as the metal mark 3 passes through the inside of the detection unit 11a. Therefore, accurate length information can be obtained.

[0014]

Since the hose with the length information of the present invention has the metal mark, the metal sensor can detect the metal mark and obtain the length information. The metal sensor is less susceptible to external factors and can perform accurate mark detection as compared with a conventionally used optical sensor, so that the reliability of hose length information detection is improved. In the second invention, since the metal mark is embedded inside the hose main body, there is no fear that the metal mark will fall off due to friction or rust. In the third invention, since the metal mark is made of ink containing magnetic metal fine powder, it is easy to install the metal mark on the hose body. When this ink is used, characters and figures can be printed, so that metal marks of various shapes can be easily formed. Therefore, not only the length information but also other information such as a product type and a product name can be simultaneously displayed. According to the fourth aspect of the present invention, since the metal mark made of the metal wire or the metal foil is wound around the reinforcing thread in a coil shape, the metal wire or the metal foil does not impair the flexibility and elongation of the hose. Further, since the hose body is composed of a plurality of layers and the metal mark is provided between any of the layers, there is no fear that the metal mark will fall off due to friction or rust as in the second invention.
