Abstract

A fully automated modular primer processing unit is provided that is controllable, tailorable and increases the safety of operators over current methods. The modular primer process unit is comprised of a plurality of stations. Exemplary stations include: 1) primer cup insertion station, 2) an energetic filling station, 3) a drying station, 4) a consolidation unit, and 5) an anvil insertion station. Additional stations such as a tray feed station, a primer sealing station and a tray stacking station may also be configured with the modular primer processing unit.

Claims (17)

1. A modular primer processing unit comprising:

a. primer cup insertion station comprising a vibratory cup feeder, cup escapement, a first multi-axis gantry robot; wherein said cup escapement comprises a bottom cup separator and a top cup separator, and servo-motor driven actuators;

b. energetic filling station in communication with the primer cup insertion station, wherein said energetic filling station comprises a second multi-axis gantry robot and positive displacement pneumatic valves for dispensing homogenous energetic, mixture maintained in its homogenous state, into each primer cup;

c. drying station in communication with the energetic filling station, wherein said drying station comprises a vacuum chamber assembly, tray stacking and tray de-stacking apparatus;

d. consolidation station in communication with the drying station wherein the consolidation station comprises consolidation press and a third multi-axis gantry robot;

e. anvil insertion station in communication with the consolidation station, wherein said anvil insertion station comprises an anvil vibratory feeder and an anvil escapement, wherein said anvil escapement comprises a bottom anvil separator and a top anvil separator, and servo-motor driven actuators; and wherein the modular primer processing unit is a fully automated manufacturing line.

2. The modular primer processing unit of claim 1 , wherein each station comprises sensors selected from the group consisting of three-dimensional scanning lasers, two-dimensional scanning laser, pressure sensor, moisture sensor, photoelectric sensor, proximity sensor, and imaging sensor.

3. The modular primer processing unit of claim 1 , wherein the consolidation station comprises a foil disc application apparatus, a plurality of press heads and feedback sensor to sense the force of consolidation.

4. The modular primer processing unit of claim 1 , wherein the anvil insertion station further comprises a three dimensional scanner to create virtual images of the anvil profiles located in said station.

5. The modular primer processing unit of claim 1 , wherein the sealant station comprises a sealant assembly wherein said assembly is comprised of a sealant, dispensing valve, and assembly for curing said sealant.

6. The modular primer processing unit of claim 1 , further comprising a tray feed station.

7. The modular primer processing unit of claim 1 , further comprising a tray stacking station.

8. The modular primer processing unit of claim 7 , wherein the stacking station comprises tray indexing apparatus and tray stacking apparatus.

9. The modular primer processing unit of claim 1 , wherein the trays are transferred through the plurality of stations using servo-motors mounted below the process trays.

10. The modular primer processing unit of claim 1 , wherein the positive displacement pneumatic valves is comprised of pneumatic actuated valves, auger and digitally controlled valves.

11. The modular primer processing unit of claim 1 , further comprising a plurality of processing trays wherein the processing trays comprises grooves process tray edges and fixed pins.

12. A process for automated primer manufacturing comprising feeding a plurality of primer cups into the modular primer processing unit of claim 1 to produce finished energetic primers.
