Abstract

Actuating an air conveyor device is disclosed, including: causing an airflow to be generated by an airflow generator of an air conveyor device, wherein the airflow generator is configured to cause the airflow to enter an intake port of the air conveyor device and exit from an outlet port of the air conveyor device in response to receiving air at an air input port of the air conveyor device; causing a target object to be captured by the air conveyor device using the airflow; activating a positioning actuator mechanism to position the air conveyor device; and causing the target object to be ejected from the air conveyor device.

First claim

What is claimed is:

1. A sorting device, comprising:
a positioning actuator mechanism;
an air conveyor device coupled to the positioning actuator mechanism, wherein the positioning actuator mechanism is configured to actuate the air conveyor device, wherein the air conveyor device comprises:
a housing that includes an intake port and an outlet port, wherein an internal through-passageway connects the intake port and the outlet port;
an air input port; and
an airflow generator defined within the housing, wherein the airflow generator is coupled to the air input port, wherein the airflow generator is configured to cause an airflow to enter the intake port and exit the outlet port in response to a supply of air into the air input port; and

an ejection mechanism associated with the housing, wherein the ejection mechanism is configured to eject air or an object out of the intake port of the air conveyor device.

2. The sorting device of claim 1 , wherein the airflow generator comprises:
an air distribution ring disposed within the housing, wherein the air distribution ring is coupled to the air input port; and
a plurality of air ejector nozzles disposed around the air distribution ring, wherein the plurality of air ejector nozzles is positioned within the housing to direct air entering the air distribution ring from the air input port into the internal through-passageway in a direction away from the intake port and towards the outlet port.

3. The sorting device of claim 1 , further comprising a material obstruction sensor that outputs a feedback signal.

4. The sorting device of claim 1 , the air conveyor device further comprising:
a funnel configured to direct the airflow into the internal through-passageway when the airflow generator is operating.

5. The sorting device of claim 1 , wherein the positioning actuator mechanism comprises one or both of a rotational positioning mechanism and a linear positioning mechanism.

6. The sorting device of claim 5 , wherein the positioning actuator mechanism comprises the rotational positioning mechanism configured to rotate the air conveyor device to a first position in response to receiving a position control signal.

7. The sorting device of claim 5 , wherein the positioning actuator mechanism comprises the rotational positioning mechanism configured to rotate the air conveyor device to one of a plurality of different positions in response to receiving a position control signal.

8. The sorting device of claim 5 , wherein the positioning actuator mechanism comprises the linear positioning mechanism configured to move the air conveyor device to a first position in response to receiving a position control signal.

9. The sorting device of claim 5 , wherein the positioning actuator mechanism comprises the linear positioning mechanism configured to move the air conveyor device to one of a plurality of different positions in response to receiving a position control signal.

10. The sorting device of claim 5 , wherein the positioning actuator mechanism comprises at least one articulating member configured to move the air conveyor device to one of a plurality of different positions in response to receiving a position control signal.

11. The sorting device of claim 1 , wherein the air input port comprises a first air input port, wherein the airflow generator comprises a first airflow generator, wherein the ejection mechanism associated with the housing comprises a second air input port and a second airflow generator defined within the housing, wherein the second airflow generator is coupled to the second air input port, wherein the second airflow generator comprises:
a second air distribution ring disposed within the housing, wherein the second air distribution ring is coupled to the second air input port; and
a second plurality of air ejector nozzles disposed around the second air distribution ring, wherein the second plurality of air ejector nozzles are positioned within the housing to direct air entering the second air distribution ring from the second air input port into the internal through-passageway in a direction away from the outlet port and towards the intake port.

12. The sorting device of claim 1 , wherein the ejection mechanism associated with the housing comprises a mechanical material ejector mechanism coupled to or mounted to the housing, wherein the mechanical material ejector mechanism comprises an actuator coupled to an extendable strike member, wherein the mechanical material ejector mechanism is configured to activate the extendable strike member to extend from the intake port in response to a control signal.

13. The sorting device of claim 12 , wherein the mechanical material ejector mechanism is operated by a pneumatic switch.

14. The sorting device of claim 12 , wherein the mechanical material ejector mechanism is operated using a solenoid.

15. A sorting system, comprising:
a processor configured to:
cause an airflow to be generated by an airflow generator of an air conveyor device, wherein the airflow generator is configured to cause the airflow to enter an intake port of the air conveyor device and exit from an outlet port of the air conveyor device in response to receiving air at an air input port of the air conveyor device;
cause a target object to be captured by the air conveyor device using the airflow;
activate a positioning actuator mechanism to position the air conveyor device; and
cause the target object to be ejected from the air conveyor device; and

a memory coupled to the processor and configured to provide the processor with instructions.

16. The sorting system of claim 15 , wherein the processor is further configured to:
select the target object to capture by the air conveyor device; and
activate the positioning actuator mechanism to move the air conveyor device to facilitate capture of the target object.

17. The sorting system of claim 15 , wherein to activate the positioning actuator mechanism to position the air conveyor device comprises to:
determine a deposit location corresponding to the target object; and
determine a new position for the positioning actuator mechanism to move the air conveyor device to based at least in part on the deposit location.

18. The sorting system of claim 15 , wherein the target object is caused to be ejected from the air conveyor device at least partially concurrently with the activating of the positioning actuator mechanism.

19. The sorting system of claim 15 , wherein causing the target object to be ejected from the air conveyor device comprises to activate a mechanical material ejector mechanism associated with the air conveyor device.
