Small caliber production ammunition machine with novel measuring location and device
View Patent ↗Herein described is a small caliber ammunition production loading machine with a novel measuring location and device. The machine will load one cartridge at a time and is referred to as a ‘single-out” machine (see FIG. 1 ). The machine will be similar in nature to existing loading machines with the following key novel aspects: a) The cartridge overall length (OAL) will be measured both as an overall dimension which is industry standard and also at a key datum location on a bullet's ogive. Measuring to a repeatable datum point on the bullet's ogive gives a more accurate representation of the cartridge's ballistic ability.
1. An ammunition production loading machine comprising:
A. A Case Load Station wherein empty cases are loaded into a removeable case insert of an insert disk;
B. A Powder Load Station wherein powder is delivered to said cases and said powder is measured by a physical powder sensor and a laser powder measuring check;
C. A Bullet Load Station wherein a bullet is loaded into each of said cases;
D. A Case Bullet Crimp Station comprised of an upper ram driven crimp tool, which crimps said bullets to said cases to form an assembled cartridge;
E. A Process Control Station comprised of an overall length laser height check comprised of a first laser micrometer and an ogive length check comprised of a tool, wherein said tool form fits said bullet and contacts an ogive of the bullet when said tool is lowered, and wherein a second laser micrometer measures a position of a flag of said tool with respect to a fixed base point of said cartridge;
F. A Reject Station, which will remove any assembled cartridge from said insert disk if said cartridge overall length and ogive length check measurements are not within a specified tolerance set at said Process Control Station;
G. A Eject Station wherein a pneumatically activated pusher removes said cartridges, which pass said Process Control Station onto an internal mounted conveyor;
wherein a motor drives a center mounted crankshaft with a chain, sprockets and clutch, which drives an upper and lower ram up and down to perform the functions of each of the machine's stations and said motor also drives a 24-position indexer, which rotates said insert disk through the machine's stations.
2. The ammunition production loading machine of claim 1 , wherein said ogive length check second laser micrometer is further comprised of a laser transmitter and a laser receiver.
3. An ammunition production loading machine ogive length check comprising:
an overall length laser height check comprised of a first laser micrometer;
a tool, wherein said tool form fits a bullet and contacts an ogive of the bullet of a loaded cartridge when said tool is lowered; and
wherein said tool is further comprised of a flag mounted to said tool, wherein a second laser micrometer measures a position of said flag with respect to a fixed cartridge base point.
