Abstract

A high throughput system for sorting a plurality of different small object types into a plurality of cells of a plurality of small object cassettes is provided. The system comprises: at least one small object cassette having a plurality of small object cells; an automated conveyor system for transporting the cassette(s) from a loading location to a unloading location on the conveyor system; at least one cassette filling station disposed over the conveyor system such that the conveyor system extends under a small object distribution subsystem of each respective cassette filling station; and a computer based central control system structured and operable to control various operations of the conveyor system and each cassette filling station.

First claim

What is claimed is:

1. A high throughput system for sorting a plurality of different small object types into a plurality of cells of at least one small object cassette, said system comprising:
the at least one small object cassette comprising a plurality of inter-connected small object cells integrally formed in the at least one small object cassette, the inter-connected, integrally formed small object cells structured to retain small objects;
an automated closed-circuit conveyor system comprising a plurality of sequential independently controlled track sections, the conveyor system structured and operable to transport the cassette(s) from a cassette loading station around the closed-circuit conveyor system, through at least one cassette processing station, and to a cassette unloading station;
the at least one cassette processing station accessible by the conveyor system and structured and operable to deposit one of a plurality of groups of the small objects into selected ones of the inter-connected small object cells integrally formed in the at least one small object cassette; and
a central control system comprising a computer-based controller communicatively connected to at least the conveyor system and each cassette processing station, the central control system structured and operable to control operations of each independently controlled track section of the conveyor system and each cassette processing station.

2. The system of claim 1 , wherein each processing station comprises:
at least one small object counting and parsing subsystem structured and operable to parse the plurality of groups of small objects from a bulk quantity of the small objects, each group of small objects comprising a respective number of small objects stipulated by the central control system; and
a small object distribution subsystem structured and operable to receive each parsed group of small objects and deposit each parsed group of small objects into a respective one of the small object cells of a respective one of the cassette(s) stipulated by the central control system as the respective cassette is positioned adjacent the small object distribution subsystem via the conveyor system.

3. The system of claim 2 , wherein each small object counting and parsing subsystem comprises:
a bulk small object bin structured and operable to retain the bulk quantity of small objects of a selected type;
an upper small object bin structured and operable to retain small objects received from the bulk small object bin;
a decelerator connected to the bulk small object bin by a vacuum conduit structured and operable to transport a plurality of small objects from the bulk small object bin to the decelerator, the decelerator additionally connected to the upper small object bin, wherein the decelerator is structured and operable to decelerate a speed of the small object being transported from the bulk small object bin and deposit them into the upper small object bin;
a small object singulator and counter connected to the upper small object bin, the small object singulator and counter structured and operable to extract small objects from the upper small object bin, count the small objects and parse the small objects into the groups of small objects wherein each group of small objects comprises the respective number of small objects stipulated by the central control system; and
a small object queuing assembly structured and operable to receive the groups of small objects from the small object singulator and counter and deposit each group of small objects into the small object distribution subsystem.

4. The system of claim 3 , wherein the small object queuing assembly comprises:
a first queuing stage fluidly connected to the small object singulator and counter and structured and operable to receive and temporarily retain each group of small objects from the small object singulator and counter; and
a second queuing stage fluidly connected to the first queuing stage and structured and operable to receive and temporarily retain each group of small objects from the first queuing stage.

5. The system of claim 4 , wherein the small object distribution subsystem comprises:
a multi-cell buffer tray comprising a plurality of small object buffer cells;
a small object transport and deposition assembly structured and operable to deposit groups of small objects received from the small object queuing assembly into selected small object buffer cells; and
a sluice tray that is movable between a Closed position and an Open position, wherein when in the Closed position the sluice tray covers the bottom of buffer tray such that groups of small objects deposited in the small object buffer cells are retained within the small object buffer cells, and when in the Open position the sluice tray uncovers the bottom of the buffer tray such that the groups of small objects deposited in the buffer cells are allowed to fall into corresponding small object cells of a small object cassette positioned under the buffer tray via the automated conveyor system.

6. The system of claim 5 , wherein the small object deposition assembly comprises at least one third queuing stage mounted to an X-Y transport, the third queuing stage(s) structured and operable to receive and temporarily retain each group of small objects from the second queuing stage and deposit each group of small objects into a respective the selected small object buffer cell, the X-Y transport structured and operable to position the third queuing stage(s) under the second queuing stage and then subsequently over the respective small object buffer cell.

7. The system of claim 6 , wherein at least one of:
the first queuing stage comprises a first stage vibratory wall structured and operable to vibrate to prevent small objects from becoming lodged within the first queuing stage;
the second queuing stage comprises a second stage vibratory wall structured and operable to vibrate to prevent small objects from becoming lodged within the second queuing stage; and
the third small object queuing stage comprises a third stage vibratory wall structured and operable to vibrate to prevent small objects from becoming lodged within the third queuing stage.

8. A high throughput system for sorting a plurality of different small object types into a plurality of cells of at least one small object cassette, said system comprising:
the at least one small object cassette comprising a plurality of inter-connected small object cells integrally formed in the at least one small object cassette, the inter-connected, integrally formed small object cells structured to retain small objects;
an automated closed-circuit conveyor track comprising a plurality of sequential independently controlled track sections, the conveyor system structured and operable to transport the cassette(s) from a cassette loading location around the closed-circuit conveyor track, through at least one cassette processing station, and to a cassette unloading location;
the at least one cassette processing station disposed over the conveyor track such that the conveyor track extends through each cassette processing station and under a small object distribution subsystem of each respective cassette processing station, wherein the at least one cassette processing stations is structured and operable to deposit one of a plurality of groups of small objects into selected ones of the inter-connected small object cells integrally formed in the at least one small object cassette; and
a central control system comprising a computer-based controller communicatively connected to at least the conveyor track and each cassette processing station, the central control system structured and operable to control operations of each independe
