Abstract

An empties transport system has an airstream transport device with an empties transport conduit, which has a first attachment point for attachment to the reverse vending machine and a second attachment point for attachment to the empties collection container, and an airstream generator, which is attached to the empties transport conduit and is designed to make available, in the empties transport conduit, a transporting airstream by means of which the empties passing via the first attachment point from the reverse vending machine the empties transport conduit are moved to the empties collection container, and an airlock device which is arranged on the first attachment point and via which the empties are transferable from the reverse vending machine to the empties transport conduit.

First claim

What is claimed is:

1. An empties transport system for automatic transport of empties from a reverse vending machine to an empties collection container, with:
an airstream transport device, including:
an empties transport conduit having a first attachment point for attachment to the reverse vending machine and a second attachment point for attachment to the empties collection container, and
an airstream generator, which is attached to the empties transport conduit and is designed to make available, in the empties transport conduit, a transporting airstream by means of which the empties passing via the first attachment point from the reverse vending machine into the empties transport conduit are movable to the empties collection container,

an airlock device arranged on the first attachment point of the reverse vending machine and attachable between the reverse vending machine and the empties transport conduit, and via which the empties are transferable from the reverse vending machine to the empties transport conduit, and which has at least one airlock gate for automatically controlled, selective separation of the empties transport conduit from the reverse vending machine, and
an automatic control device which is connected to the airlock device in order to automatically control an opening and closing actuation of the at least one airlock gate as a function of the empties which are to be carried away via the empties transport conduit and which are delivered to the airlock device from the reverse vending machine.

2. The empties transport system as claimed in claim 1 , wherein the airstream generator, during the operation of the empties transport system, makes the transporting airstream permanently available.

3. The empties transport system as claimed in claim 2 , wherein the airlock device has a second airlock gate, and wherein the control device is designed to control the opening and closing actuation of the first and the second airlock gate of the airlock device in such a way that at least substantially only one of the first and the second airlock gates is opened.

4. The empties transport system as claimed in claim 1 , wherein the airlock device and/or the first attachment point are/is designed in such a way that the transfer of the empties from the airlock device to the empties transport conduit is effected at least substantially exclusively by an air flow underpressure which is generated in the empties transport conduit and acts on the empties present in the airlock device.

5. The empties transport system as claimed in claim 1 , wherein the empties transport conduit has a conduit diameter which is greater than the greatest dimension of the empties, such that the empties in the empties transport conduit are freely movable at least substantially in all directions.

6. An empties return system, comprising:
a reverse vending machine including,
an empties admission opening in a front side of the reverse vending machine through which empties can be introduced into the reverse vending machine,
a first attachment point on the rear side of the vending machine including an opening,

an empties collection container including a second attachment point, and
a transport system for automatic transport of empties from the reverse vending machine to the empties collection container, comprising:
an airstream transport device, including:
an empties transport conduit having at least a first attachment point for attachment to the first attachment point of the reverse vending machine and at least a second attachment point for attachment to the second attachment point of the empties collection container,
an airstream generator, which is attached to the empties transport conduit and is designed to make available, in the empties transport conduit, a transporting airstream by means of which the empties passing via the first attachment point from the reverse vending machine into the empties transport conduit are movable to the empties collection container,

an airlock device arranged on the first attachment point of the reverse vending machine and attachable between the reverse vending machine and the empties transport conduit, and via which the empties are transferable from the reverse vending machine to the empties transport conduit, and which has at least one airlock gate for automatically controlled, selective separation of the empties transport conduit from the reverse vending machine, and
an automatic control device which is connected to the airlock device in order to automatically control an opening and closing actuation of the at least one airlock gate as a function of the empties which are to be carried away via the empties transport conduit and which are delivered to the airlock device from the reverse vending machine.

7. The empties return system as claimed in claim 6 , wherein the airlock device is arranged at a distance from the empties admission opening, and wherein the reverse vending machine has a conveyor device which is arranged between the empties admission opening and the airlock device, via which the empties introduced into the reverse vending machine through the empties admission opening can be conveyed automatically to the airlock device.

8. The empties return system as claimed in claim 6 , wherein the airlock device is arranged adjacent to the empties admission opening, wherein empties introduced through the empties admission opening transfer directly into the airlock device and get sucked into the empties transport conduit by means of the airflow underpressure.

9. The empties return system as claimed in any of claims 6 through 8 , wherein several reverse vending machines are connected to the empties transport conduit by means of a respective first attachment point in the reverse vending machine.

10. The empties return system as claimed in any of claims 6 through 8 , further having an empties compacter by which the empties delivered to the reverse vending machine are compacted by compression and/or shredding.

11. The empties return system as claimed in claim 10 , wherein the empties compacter is arranged between the empties admission opening of the reverse vending machine and the airlock device or is arranged between the second attachment point of the empties transport conduit and the empties collection container.
