Abstract

PURPOSE:To prevent a rear-end collision by dividing a rail for conveying a plurality of running bodies into three sections or more and by stopping a running body coming in a section next to the section, in which another running body exists, through forming a closed circuit between the running body and rail by means of a switching means. CONSTITUTION:An endless rail 1, on which a plurality of running bodies 2-1 to 2-3 run in the direction(a) shown by the arrow, is provided with electric wires 6-8 in addition to various trolley wires 3-5. The running bodies 2-1 to 2-3 are provided with current collectors 9-12 coming in sliding contact with the trolley wires 3-5 and electric wires 6-8 and with a controller 13. The rail 1 and electric wires 6, 8 are divided into zones 1-3 and the electric wire 7 is continuous in all sections. The electric wire 17 connects between wires 6-1 and 8-2. When the running body 2-2 comes in the zone 2 while the running body 2-1 is in the zone 1, a current flows from the controller 13 as shown by the arrow Y and the controller 13 outputs a stop signal so that the running body 2-2 is stopped. Thus, no sensor is used also in the curved part of the rail 1 and a rear-end collision is prevented securely.

(Effects of the Invention) As is clear from the above description, according to the present invention, the positions of the preceding traveling body and the following traveling body with respect to a specific section of the rail and a section adjacent thereto can be determined without using a detection means such as a sensor. When the relationship satisfies certain requirements, the following running object is stopped to avoid a rear-end collision between the moving objects, so the curved part of the rail where previously it was only possible to detect the preceding moving object with a sensor. Even in this case, it is possible to reliably prevent rear-end collisions between traveling objects.

Further, according to the present invention, since a detection means such as a sensor is not used, there is no need for a control device or its wiring.
This also has the effect of reducing equipment costs.
