困難であつた。 Conventionally, guide wire detectors for automatic guided vehicles that are guided by a metal tape pasted on the floor for guidance have been subject to the influence of metal objects other than the guiding metal tape, such as metal parts of the vehicle body, and from external sources. This makes it difficult to stably guide automatic guided vehicles.

スで覆うことを特徴とするものである。 In order to improve the above-mentioned drawbacks, the present invention covers the two detection coils of the guide wire detector with a metal case except for the surface facing the floor, so that when the guide wire detector is installed on an automatic guided vehicle, The purpose of this technology is to eliminate the influence of the metal parts of the vehicle body, as well as noise from the outside, and to enable the detection of minute guidance signals from the guidance metal tape. Two rectangular detection coils are arranged on the same plane so that one side of the same length touches each other, and the detection coil, high frequency power supply, and resistor constitute a bridge circuit with the detection coil as two sides. In a guide wire detector that is arranged parallel to the floor and guides an automatic guided vehicle by detecting a metal guide tape attached to the floor, excluding the surface of the two detection coils facing the floor. The feature is that the part is covered with a metal case.

す。 As shown in FIG. 1, the induction wire detector comprises two detection coils 1, a high frequency power source 2, and a resistor 3 to form a bridge circuit with the detection coil 1 as two sides. Tape 4 is detected. However, if this guide wire detector is attached to the automatic guided vehicle 5 as is, it will be affected by the metal parts of the vehicle body and it will be difficult to stably guide the automatic guided vehicle 5 due to external noise. In the invention, as shown in FIG. 2, by covering the two detection coils 1 with a metal case 7 except for the surface facing the floor 6, the shape of the vehicle body when the guide wire detector is attached to the automatic guided vehicle 5 is reduced. The influence of the metal body and noise from the outside can be removed, and the automatic guided vehicle 5 shows stable running along the guiding metal tape 4 attached to the floor surface 6.

ができる点実用的価値甚だ大なるものである。 As mentioned above, by implementing the present invention, the guide line detector for automatic guided vehicles can eliminate the influence and noise of metal objects other than the guide road surface, and can detect minute signals from the guide metal tape. Therefore, it has great practical value in that it allows automatic guided vehicles to run stably along guide lines.
