The present invention has been proposed in view of the above-mentioned problems of the prior art, and is suitable for a fuel oil delivery system capable of reliably reading information even when different types of detectors are inserted into the same insertion slot. It is an object of the present invention to provide an oil mixture prevention device.

In order to achieve such a problem, the oil mixing prevention device of the present invention is provided with a tag reader on each hatch of the loading arm or tank lorry of the oil tank, and a tag is provided on each hatch or loading arm of the tank lorry to read the tag. A tag is inserted into the machine to prevent erroneous loading, a tag reader is provided on the unloading hose of the tank truck, and a tag is provided on the lubrication port of the oil storage tank of the refueling station, and the tag is attached to the tag reader. In an oil mixing prevention device that is inserted to prevent erroneous unloading, the tag is equipped with one of an information storage means, a magnetic piece, or an IC tag on a substrate having the same shape, and there are a plurality of tag readers. information storage means for pre-Symbol tag together when the base species of tags includes one of the insertion slot can be inserted, constituted by providing magnetic strips, or a plurality of types of reading means suitable for reading the IC tag to a substrate Has been done.

According to the present invention, even tags equipped with different types of sensors can be reliably read by simply loading them into a common insertion slot of the same tag reader, simplifying work and preventing mistakes. Can be planned.

The figure which shows the outline of one Example of the tag reader of this invention and two kinds of tags which can read by this. FIG. (A) is a cross-sectional view of the tag reader shown with the outer shell case removed, and FIG. (B) is a cross-sectional view of the tag. Sectional view showing the tag loaded in the readable position of the tag reader. The figure which shows an embodiment of a guide member. The figure which shows the tag insertion process.

Therefore, the details of the present invention will be described below with reference to the illustrated examples.
FIG. 1 shows a tag reader provided in each hatch of a loading arm or a tank lorry of an oil tank, and a tag provided in each hatch or a loading arm of a tank lorry. The tag is inserted into the tag reader and erroneously loaded. A tag reader is installed on the unloading hose of the tank truck, and a tag is installed on the lubrication port of the oil storage tank of the gas station to prevent erroneous unloading by inserting the tag into the tag reader. An embodiment of the oil mixture prevention device of the present invention used for the device is shown.

The tag reader 1 is provided with a cable 2 connected to a control means (not shown) at one end and a common insertion port 3 at the other end, and is provided on a tag substrate 8 having the same outer shape. Sensors, that is, reading means 4 and 5 for reading IC tags and magnetic pieces are built-in.

FIG. 2 shows the cross-sectional structure of the tag reader and the tag to be detected by removing the outer shell case 1a, and the tag 6 is one surface of the substrate 8, that is, the reading means in the tag reader. A chevron-shaped convex portion 9 is provided on a surface different from the surface facing the surface on which the 4 and 5 are arranged, and a concave portion 10 is provided on the rear end side beyond the convex portion 9. Reference numeral 1b in FIG. 1 indicates a reinforcing rib.

As shown in FIG. 3, the roller member 11 is in contact with the back surface of the substrate 8 of the tag 6 (7), that is, the surface on which the convex portion 9 and the concave portion 10 are formed, and the tag 6 (7) is placed at a regular reading position. When loaded, it fits into the recess 10 of the tag and is always urged on the reading means 4 and 5 sides.

Further, in the tag reader 1, a substrate 12 is housed therein, which includes an information storage means of the tag 6 (7), two types of reading means 4 and 5 for reading a magnetic piece or an IC tag, and this implementation. In the example, a magnetic sensor and an IC tag sensor (wireless ID chip reader) are provided on the front and back sides in this embodiment.

If the two types of reading means 4 and 5 can be arranged on the same surface due to the space of the substrate 12, the two types of reading means 4 and 5 are arranged together on one surface of the substrate 12. Needless to say, it's good.
According to this embodiment, the maintenance work can be performed only on one surface of the substrate 12, so that the work efficiency is improved.

Since a plurality of types of reading means are provided on the same substrate 12 in this way, it is possible to reduce the size and reduce the number of parts by sharing the substrate.

Further, as shown in FIG. 4, the insertion port 3 is preferably made of a non-magnetic and electromagnetic wave shielding material, aluminum or its alloy, or brass, and the back surface and both side surfaces of the tags 6 and 7 are regulated and predetermined. A guide member 13 having a "U" -shaped cross section is inserted so that the guide member 13 can be guided to the position.

The guide member 13 functions as a shielding member for limiting a detection area in which communication by electromagnetic waves is possible only when the tags 6 and 7 are located in the normal reading area and communication is not possible in other positions. Then, the window 14 of the guide member 13 fulfills the function. The window 14 of the guide member 13 can prevent an error due to reading at an improper position and can read the information of the IC tag of the substrate reliably and accurately.

Reference numerals 15 and 16 in the drawing indicate a magnetic material sensor provided on one surface of the substrate and an antenna constituting the IC tag sensor for reading the IC tag, respectively.

Further, for a tag using a magnetic material, the detectable region is narrow and detection can be performed only when the tag is loaded in an appropriate position, so that the detection region limiting means as described above is not required.

In this embodiment, the first type tag 7 will be described as an example, but the same applies to the other types of tags 6, so the description thereof will be omitted.
When the tag 7 is inserted into the insertion slot 3 and pushed inward, the surface of the substrate is pressed toward the reading means 4 and 5 by the roller member 11, and both side surfaces are restricted by the guide member 13 to move to the specified position in the back. do.

In this insertion process, the roller member 11 rides on the climbing slope of the convex portion 9 of the substrate and comes into contact with it (see FIG. 5). When the tag 7 is released at a halfway stage that does not exceed the top of the convex portion 9, the tag 7 is pushed back to the insertion port side by the component force generated by the elastic pressure of the roller member 11. That is, in this insertion process, the detection area of the electromagnetic wave is limited by the guide member 13, and mutual communication becomes impossible.

On the other hand, when the tag 7 is pushed in until the roller member 11 passes the apex of the convex portion 9, the component force of the roller member 11 acts on the downward slope of the convex portion 9 in the direction of pulling in the tag 7, so that the roller member is placed in the concave portion 10. 11 is fitted and the tag is fixed in the default position, that is, the regular reading position (see FIG. 3). That is, in this process, the detection area is not limited and communication is possible.

When the tag 7 is pulled out for some reason after the reading is completed, the roller member 11 is lifted along the slope and moves over the convex portion 9 to the outside of the readable area.
This makes it possible to detect the disconnection of the unloading hose during unloading.
