Abstract

A nozzle system that includes an improved air nozzle is provided. In one embodiment, the nozzle has an inlet and an outlet. An air source is connected with the nozzle through a conduit and generates an air flow using a high flow centrifugal blower. The nozzle is connected with and part of an air-driven orientation device.

Claims

1. An air-driven orientation device configured to orient at least one article, the air-driven orientation device comprising:

an air supply source including a high flow centrifugal blower for generating a low-pressure air flow less than approximately 10 pounds per square inch (psi);

a conduit having an inlet coupled with an outlet of the air supply source; and

a nozzle having an inlet coupled with an outlet of the conduit, wherein the nozzle comprises a nozzle body having a nozzle inlet, a nozzle outlet, and an annular wall defining a first passage that extends through the nozzle body and which couples the nozzle inlet to the nozzle outlet, wherein the nozzle is capable of receiving the low pressure air flow from the air supply source at a first velocity and outputting an air flow having a second velocity which is 4 to 16 times greater than the first velocity;

wherein the nozzle includes an inside wall having a first section and a second section, wherein the first section has a first inside diameter (ID) that varies along a longitudinal axis of the nozzle, wherein the portion of the inside wall that is part of the first section converges such that the first ID decreases as the inside wall transitions away from the inlet, wherein the second section has a generally constant second ID which is generally less than the first ID at the inlet of the nozzle.

2. The device of claim 1, wherein the low-pressure air flow has a flow rate of between approximately 50-2000 cubic feet per minute (CFM).

3. The device of claim 1, wherein the conduit includes a flow divider configured to distribute the air flow to multiple outlets, wherein each outlet is connected with a nozzle.

4. The device of claim 1, wherein in the first section of the inside wall gradually converges such that the first ID gradually decreases beginning from the inlet along the length of the first section and moving towards the outlet, and wherein a transition point occurs at a point along the inside wall where the first ID is approximately equal to the second ID, and wherein the second section begins at the transition point and extends for the remainder of the length of the nozzle, terminating at the nozzle outlet.

5. An air-driven orientation device configured to orient at least one article, the air-driven orientation device comprising:

an air supply source including a high flow centrifugal blower for generating low-pressure air flow through an outlet of the air supply source, wherein the low pressure air flow is less than approximately 10 pounds per square inch (psi); and

a nozzle having an inlet coupled with an outlet of the air supply source, wherein the nozzle comprises a nozzle body having a nozzle inlet, a nozzle outlet, and an annular wall defining a first passage that extends through the nozzle body and which couples the nozzle inlet to the nozzle outlet, wherein the nozzle is capable of receiving the low pressure air flow from the air supply source at a first velocity and outputting an air flow having a second velocity which is 4 to 16 times greater than the first velocity;

wherein the nozzle includes an inside wall having a first section and a second section, wherein the first section has a variable or changing first inside diameter (ID), wherein the portion of the inside wall that is part of the first section converges such that the first ID decreases as the inside wall transitions away from the inlet, wherein the second section has a generally constant second ID which is generally less than the first ID at the inlet of the nozzle.

6. The device of claim 5, wherein the low-pressure air flow has a pressure of between approximately 1-10 pounds per square inch (psi) and a flow rate of between approximately 50-2000 cubic feet per minute (CFM).

7. The device of claim 5, further comprising a conduit which includes a flow divider configured to distribute the air flow to multiple outlets, wherein each outlet is connected with a nozzle.
