Abstract

The guidepath includes: a magnet guide tape which carries S pole, and guides a carrier vehicle in a first direction by the S pole by being arranged on a floor so as to extend in the first direction; a magnet guide tape which carries S pole, and guides the carrier vehicle in a second direction by the S pole by being arranged on the floor so as to extend in a second direction which intersects the first direction; and a magnetic body tape which is arranged at a side of the magnet guide tape at a position above which a marker sensor passes upon the carrier vehicle being guided by the magnet guide tape, and suppresses N pole.

First claim

What is claimed is:

1. A guidepath for a carrier vehicle which is disposed on a floor surface which guides a carrier vehicle having a first magnetism sensor which detects a first magnetism, which is one magnetism among S pole and N pole; and
a second magnetism sensor which is disposed at a position distanced in a width direction relative to the first magnetism sensor, and detects a second magnetism which is the other magnetism among S pole and N pole, the guidepath comprising:
a first path magnetic tape which carries a first magnetism, and by being arranged on the floor surface so as to extend in a first direction, guides the carrier vehicle in the first direction by way of the first magnetism;
a second path magnetic tape which carries the first magnetism, and by being disposed on the floor surface so as to extend in a second direction which intersects with the first direction, guides the carrier vehicle in the second direction by way of the first magnetism; and
a suppression tape which is disposed at a position on a side of the second path magnetic tape, over which the second magnetism sensor passes upon the vehicle carrier being guided by the first path magnetic tape.

2. The guidepath for a carrier vehicle according to claim 1 , wherein the suppression tape has a predetermined length along the second path magnetic tape, and permits deviation in position when the second magnetism sensor passes thereover.

3. The guidepath for a carrier vehicle according to claim 1 , wherein the first magnetism sensor and the second magnetism sensor have substantially the same height of a detection surface.

4. The guidepath for a carrier vehicle according to claim 2 , wherein the first magnetism sensor and the second magnetism sensor have substantially the same height of a detection surface.

5. The guidepath for a carrier vehicle according to claim 1 , wherein the suppression tape includes a magnetic body.

6. The guidepath for a carrier vehicle according to claim 2 , wherein the suppression tape includes a magnetic body.

7. The guidepath for a carrier vehicle according to claim 3 , wherein the suppression tape includes a magnetic body.

8. The guidepath for a carrier vehicle according to claim 4 , wherein the suppression tape includes a magnetic body.
