CLAIMS

1. An apparatus for automated filling of cartridges of e-vapor devices, comprising: a filling drum configured to receive at least one cartridge of an e-vapor device;

a needle assembly including at least one hypodermic needle, the needle assembly configured to transition between a lowered state and a raised state, the lowered state being where the at least one hypodermic needle is moved down into the at least one cartridge, the raised state being where the at least one hypodermic needle is lifted up and away from the at least one cartridge;

a pump assembly configured to pump a pre-vapor formulation into the at least one cartridge when the needle assembly is in the lowered state, the pump assembly including a variable amplitude cam system configured to adjust an amount of the pre-vapor formulation for pumping to the at least one cartridge without changing start and stop times for the pumping.

2. The apparatus of claim 1 , wherein the filling drum is configured to rotate and to receive the at least one cartridge while in motion, a time period for the pumping coinciding with at least a 250 degree rotation of the filling drum.

3. The apparatus of claim 1 or 2, wherein the needle assembly is configured to move the at least one hypodermic needle radially within the at least one cartridge during the pumping.

4. The apparatus of claim 1 , 2 or 3, wherein the pump assembly is configured to pump the pre-vapor formulation into the at least one cartridge received by the filling drum while the filling drum is in motion.

5. The apparatus of any preceding claim, wherein the pump assembly is configured such that a time period for the pumping of the pre-vapor formulation remains constant and independent of adjustments to the amount of the pre-vapor formulation for pumping to the at least one cartridge.

6. The apparatus of any preceding claim, further comprising:

a feed drum configured to deliver the at least one cartridge to the filling drum.

7. The apparatus of any preceding claim, further comprising:

an exit drum configured to remove the at least one cartridge from the filling drum,

wherein the filling drum, the feed drum, and the exit drum are configured to rotate synchronously such that the at least one cartridge is conveyed in a continuous motion from the feed drum to the exit drum via the filling drum.

8. A pump assembly for automated filling of cartridges of e-vapor devices, comprising:

a pump cam follower configured to interact with a pump cam to effectuate a first displacement corresponding to a general drawing action and to effectuate a second displacement corresponding to a general pumping action for a pre-vapor formulation; and

a variable amplitude cam system configured to translate the general drawing action to an adjusted drawing action and to translate the general pumping action to an adjusted pumping action for the pre-vapor formulation.

9. The pump assembly of claim 8, wherein the pump cam follower is configured to ride within a pump track extending around the pump cam, the pump cam being a barrel cam.

10. The pump assembly of claim 8 or 9, wherein the pump cam follower is configured to effectuate a downward displacement corresponding to the general drawing action and an upward displacement corresponding to the general pumping action.

1 1. The pump assembly of claim 8, 9 or 10, wherein the variable amplitude cam system includes a pivotable track configured to swing downwards about a track pivot to translate the general drawing action to the adjusted drawing action and to swing upwards about the track pivot to translate the general pumping action to the adjusted pumping action.

12. The pump assembly of any of claims 8 to 1 1 , wherein the variable amplitude cam system includes an adjuster bolt configured to be rotated to attain a desired translation of the general drawing action and the general pumping action to the adjusted drawing action and the adjusted pumping action, respectively.

13. The pump assembly of any of claims 8 to 12, wherein the general drawing action and the general pumping action are facilitated with an auxiliary slide, and the adjusted drawing action and the adjusted pumping action are facilitated with a primary slide.

14. A variable amplitude cam system for an apparatus for automated filling of cartridges of e-vapor devices, comprising:

a pivotable track configured to swing about a track pivot;

an adjuster block arrangement interfacing with the pivotable track such that a swinging of the pivotable track about the track pivot translates to a displacement of the adjuster block arrangement; and

an adjuster bolt configured to mate with the adjuster block arrangement via a thread engagement, the adjuster bolt being rotatable to effectuate an incremental shift of the adjuster block arrangement along the adjuster bolt so as to adjust an amount of pre-vapor formulation for pumping to the cartridges.

15. The variable amplitude cam system of claim 14, wherein the adjuster block arrangement is configured to shift toward the track pivot when the adjuster bolt is rotated in a first direction so as to decrease the amount of pre-vapor formulation for pumping to the cartridges and configured to shift away from the track pivot when the adjuster bolt is rotated in an opposite second direction so as to increase the amount of pre-vapor formulation for pumping to the cartridges.

16. The variable amplitude cam system of claim 14 or 15, wherein the adjuster block arrangement includes an adjuster block and an adjuster block follower secured to the adjuster block, the pivotable track defining a slot path therein, the adjuster block follower configured to shift along the slot path in response to a rotation of the adjuster bolt.

17. The variable amplitude cam system of claim 14, 15 or 16, wherein the adjuster block defines an internally-threaded through hole therein, the adjuster bolt having an externally-threaded surface and a bolt head at a proximal end of the adjuster bolt, the adjuster bolt extending though the adjuster block, the externally-threaded surface of the adjuster bolt engaged with the internally-threaded through hole of the adjuster block, the adjuster bolt being rotatable via the bolt head so as to shift the adjuster block along a length of the adjuster bolt.

18. The variable amplitude cam system of any of claims 14 to 17, wherein the adjuster bolt is configured to alter a vertical displacement of the adjuster block arrangement resulting from the swinging of the pivotable track by altering a distance of the adjuster block arrangement from the track pivot.

19. The variable amplitude cam system of any of claims 14 to 18, wherein the pivotable track is configured to swing downwards to effectuate a drawing action for procuring the pre-vapor formulation from a reservoir and configured to swing upwards to effectuate a pumping action for pushing the pre-vapor formulation to the cartridges.

20. A method for automated filling of cartridges of e-vapor devices, comprising: adjusting a fill amount of pre-vapor formulation by modifying a pump stroke length with a pivotable track and an adjuster bolt while maintaining a constant time period for pumping the pre-vapor formulation into the cartridges.
