Abstract

An automated vial feed system for an automated prescription filling system. The system has a plurality of sensors located above a vial distribution table for controlling the pace of vial delivery to the table. The sensors determine the load of vials on the table and a control system uses the information as feedback to the vial delivery system.

First claim

What is claimed is:

1. An automated vial feed system for an automated prescription fulfillment system, comprising:
a vial distribution table comprised of an inbound lane and an outbound lane, a first conveyor lane for moving vials around the vial distribution table, the first conveyor lane comprised of an inside portion, middle portion and outside portion, wherein the system is configured to accept vial delivery from the inbound lane;
a first sensor positioned over or under the middle portion of the first conveyor lane for detecting the presence of vials moving on the middle portion of the first conveyor lane;
a first control processing system, the control processing system programmed with instructions executing on the processing system for: 1) receiving input from the first sensor; 2) generating a control signal to slow down the pace of vial delivery when vials are detected by the first sensor.

2. The system of claim 1 , further comprising:
a second sensor positioned over or under the inside portion of the first conveyor lane for detecting the presence of vials moving on the inside portion of the first conveyor lane; and
wherein the first control processing system is programmed with instructions executing on the processing system for: 1) receiving input from the second sensor; and 2) generating a control signal to stop vial delivery when vials are detected by the second sensor.

3. The system of claim 2 , further comprising:
a vial storage container for storing vials;
an outfeed conveyor for delivering vials from the vial storage container to the inbound lane of the vial distribution table.

4. The system of claim 3 , further comprising:
a means for providing vials from the vial storage container to the outfeed conveyor.

5. The system of claim 4 , wherein the means for providing vials from the vial storage container is an elevator mechanism.

6. The system of claim 4 , further comprising:
a second control processing system, the control processing system programmed with instructions executing on the processing system for: 1) receiving control signals from the first control processing system; 2) controlling the means for providing vials from the vial storage container based on the received control signals.

7. The system of claim 6 , wherein the second control processing system is programmed with instructions executing on the processing system for: slowing down the pace of vial delivery when vials are detected by the first sensor; 3) stopping vial delivery when vials are detected by the second sensor.
