DESCRIPTION:
BRIEF SUMMARY
The invention has for its object a pneumatic conveyor for small metallic pieces, particularly coins, for payment points.
The payment point can be particularly a toll road machine, a parking machine, a machine below gaming halls or any other apparatus receiving money and adapted to be emptied by a pneumatic conveyor line.
The status of the art can be defined by the following patents:
FR-A-2.639.336: Conveyor of the pneumatic type for transporting solid objects such as coins, comprised by a suction tube at the intake, a suction turbine, a tube for discharging air toward the exterior, a storage located below the normal point for recovering the pieces, said storage having the function of freeing by gravity the pieces in a random fashion; a suction tube connects the reception box to an assembly of separation boxes; at the end of said tube are disposed movable boxes for reception, storage and handling of the conveyed articles; said conveyors characterized by the fact that it comprises a box which serves as a flow regulator, and that the assembly of said separation boxes serves as a blockage to separate the conveyed articles from the circuit under vacuum, said assembly is disposed at the downstream end of the suction tube.
FR-A-2.703.665: pneumatic conveyor for the transfer of solid objects, such as coins, of the type using a pneumatic transport line disposed between at least two reception and storage chambers for solid objects, supplied directly by gravity or by another transfer means of said solid objects, from at least one payment point, a storage volume or a blockage maintains the vacuum created by a suction turbine whilst freeing the solid objects and at least one machine to count the money.
The conveyor comprises: as to be displaceable under the fixed reception and storage containers, flexible tube, and by a control means.
These patents describe essentially a transport device using a line from a payment point and continuous evacuation. The device for introduction into the payment point is reduced to a funnel adapted to introduce the pieces into the tube.
This embodiment has the drawback of being costly to install by the large number of tubes necessary and to use because the lines are not used for more than a small percentage of their capacity.
U.S. Pat. No. 4,131,318: apparatus to collect pieces comprising a reception chamber and a suction system to permit suction toward the reception chamber. A plurality of internal holes are disposed on the upper wall of this chamber, and a conduit connects each internal hole to a source of separated and spaced pieces. Each plug, located at the level of each internal hole, has an upper inclined shape which, in the position of closure, permits individually blocking each internal hole. A solenoid is secured to each plug to move the plug upon countering a force which maintains it closed so as to permit communication between the conduit and the receptacle chamber. Mechanisms periodically activate the suction means and the solenoids.
In this patent, each payment point is provided with an introduction device each connected by a line for the apparatus for suction and receiving the pieces.
U.S. Pat. No. 3,759,577: pieces disposed in reception units for machines using pieces fall into distributor conduits communicating with reception units and a remote collection surface. The liquid moves continuously and periodicly through the tubes and moves the pieces through the tubes and to the reception surface at which the pieces are separated from the liquid.
This apparatus does not suck objects through a conduit. On the contrary, it pushes whilst blowing and injecting water. The conduits cannot be disposed at more than a gentle slope, or on the same level.
U.S. Pat. No. 4,078,498: a system of pneumatic transport at low pressure to move a vehicle or objects along a conduit having two ends without a door subjected to atmospheric pressure. Adjacent the inlet end of the conduit, several orifices in the form of slots for the Coanda effect are present at the closure of the conduit. A tube conne
