Abstract of EP0371900
The present invention relates to a conveyor in an installation for motor vehicle
bodies electrocoating. This conveyor consists of an overhead carrier device
consisting of two parallel overhead rail carrier 1a, 1b, of a metal sledge 2 and
of four supporting arms 3a, 3b connecting the sledge 2 to the two rail carrier
1a, 1b. The invention is used for conducting electricity from an electrified
rail 1a to the sledge 2 in an electrocoating installation.
The present invention relates to a conveyor of personal vehicles in a painting
The conveyors of this type are usually composed of two rail carriers and
parallel and tobogganing on the vehicle to paint below the rail carriers, the
is linked to the two rail carriers by arm lift
The vehicle being manipulated before and after the painting itself, through the,
it is necessary that lifting the arms that connect the tracks air can be
split to the sledge.
Thus, at the end of each arm levitation rail against which it is suspended, is
ready to hang a hand that could be fixed so removable corresponding to the
In the case of a painting by electro-deposition, one of the two rails is
electrified by an electrical current of 200 to 600 volts and 500 to 800 amps.
Thus, both arms hanging at the rail drive electric current through and the
main arm lift, passes through the electrified and the vehicle landed on
But in a painting by electro-deposition, track routes that make up and down and
turns. But whatever the route of the rails, and therefore scope, power
must always pass.
However, the link between the removable and the main arm lift is such that
electrical contacts are given the itinerary of the more or less well made
and it appears the phenomena 'arc pull metal, thereby increasing friction and
reducing the quality of electrical contacts in such proportions that the power
The invention therefore seeks to eliminate this phenomenon of arcing in
conjunction hand of a conveyor installation vehicles for painting by
This invention particularly object to a conveyor of personal vehicles for
installation painting by electro-deposition consists of lifting arm connecting a
device to a air carrier in which at least one lift arm has a hand up, d '
one hand, a device for hanging the no electric current flowing between the
device hanging and and, secondly, a device conduction of electricity to the
Another object of this invention is to achieve a device such as those described
above in which the conduction of electricity consists of a medium on which is
mounted with a magnet Thursday electrically connected to a source electric
Specifically, the body support consists of an arm extending towards the
and having, under an electric contact surface of the a cage, mounted on Thursday
with his arm, inside which is placed the magnet.
The characteristics and advantages emerge as a result of the description that
follows made reference to the drawings provided solely by way of example and not
The two rail air are for example, conveyor chain and ensure progress in
parallel at the same speed, arm lifting which are set.
The rail electrified, is connected to lift arms , ending at their opposite
end to rail by a hand 4a linked to a removable
With the device according to the invention, the functions of support and
conduction of electricity have been separated, the arcing can occur, the
electrical continuity is always fully guaranteed.
