wherein, while in the closed position, the cone gripper applies pressure onto the cannabis cone that is sufficient to hold the cannabis cone; ii) a compaction rod, having a tip, for compacting cannabis in the cannabis cone, the compaction rod being reciprocable along an axis between a retracted position, wherein the tip is out of the cannabis cone, and an extended position, wherein the tip is inserted in the cannabis cone; and iii) a protective collar that is movable within the cannabis cone, coaxially thereof, near the open top thereof, so as to define a barrier between the compaction rod and the cannabis cone when the compaction rod reciprocates in the cannabis cone. ## Claims ### Claim 1 A system for compacting cannabis in a cannabis cone, the system comprising: a cone gripper that is movable between an open position and a closed position around the cannabis cone; wherein, while in the closed position, the cone gripper holding the cannabis cone; a compaction rod, having a tip, for compacting cannabis in the cannabis cone, while said cone gripper holding the cannabis cone; the compaction rod being reciprocable along an axis between a retracted position, wherein the tip is out of the cannabis cone, and an extended position, wherein the tip is inserted in the cannabis cone; a protective collar that is movable within the cannabis cone, coaxially thereof, near the open top thereof, so as to define a barrier between the compaction rod and the cannabis cone when the compaction rod reciprocates in the cannabis cone. ### Claim 2 (depends on 1) The system as recited in claim 1, further comprising: a cone holder having a bore for receiving the cannabis cone therein and for holding the cannabis cone in a first position along the axis; and a cone-raising mechanism for moving the cannabis cone up to a second position along the axis. ### Claim 3 (depends on 2) The system as recited in claim 2, further comprising an inverted funnel positioned coaxially with the axis so as to be positioned on a side of the cone gripper opposite the cone holder; the cone-raising mechanism being further configured for moving the cannabis cone through the inverted funnel up to the second position along the axis, wherein the cannabis cone extends partially out of the inverted funnel from a side thereof opposite the cone-raising mechanism. ### Claim 4 (depends on 2) The system as recited in claim 2, wherein the bore of the cone holder is frusto-conical. ### Claim 5 (depends on 2) The system as recited in claim 2, wherein the cone holder is one of a plurality of cone holders mounted in a carrousel. ### Claim 6 (depends on 2) The system as recited in claim 2, wherein the cone-raising mechanism includes a linear actuator having an output shaft and a rod secured to the output shaft so as to define an extension thereof. ### Claim 7 (depends on 6) The system as recited in claim 6, wherein the cone-raising mechanism further comprising a course length adjusting assembly that limits the course of the rod. ### Claim 8 (depends on 7) The system as recited in claim 7, wherein the rod includes an enlarged portion defining an impactor and the course length adjusting assembly includes a mechanical stop having a hole that receives the rod therethrough and that is smaller than the impactor. ### Claim 9 (depends on 1) The system as recited in claim 1, wherein the protective collar is movable by the compaction rod, when the compaction rod moves from the retracted position to the extended position, between a compact position and a generally annular position within the cannabis cone, coaxially thereof. ### Claim 10 (depends on 9) The system as recited in claim 9, wherein the protective collar includes a mounting body, jaws mounted to the mounting body for pivotal movements between close and open positions, and a biasing member for biasing the jaws towards the close position; the jaws together defining an opening to receive the compaction rod therein and being movable from the close position to the open position under the passage of the compaction rod through the opening. ### Claim 11 (depends on 10) The system as recited in claim 10, wherein the biasing member is in the form of a resilient ring that is mounted around the jaws. ### Claim 12 (depends on 11) The system as recited in claim 11, wherein the each of the jaws includes a notch to receive the resilient ring. ### Claim 13 (depends on 1) The system as recited in claim 1, wherein the cone gripper includes two fingers, each including an arcuate tapered channel that cooperates to form a frusto-conical opening that substantially complements the cannabis cone. ### Claim 14 (depends on 1) The system as recited in claim 1, wherein the compaction rod is actuated by a linear actuator. ### Claim 15 A system for compacting cannabis in a cannabis cone, the system comprising: a cone holder having a bore for receiving the cannabis cone therein and for holding the cannabis cone in a first position along an axis; a cone-raising mechanism for moving the cannabis cone up to a second position along the axis; a cone gripper that is movable between an open position and a closed position around the cannabis cone while the cannabis cone is at the second position; wherein, while in the closed position, the cone gripper holding the cannabis cone; a compaction rod, having a tip, for compacting cannabis in the cannabis cone while the cannabis rod is held by the cone gripper; the compaction rod being reciprocable along the axis between a retracted position, wherein the tip is out of the cannabis cone, and an extended position, wherein the tip is inserted in the cannabis cone; a protective collar that is movable, by the compacting rod, within the cannabis cone, coaxially thereof, near the open top thereof, so as to define a barrier between the compaction rod and the cannabis cone when the compaction rod reciprocates in the cannabis cone; wherein, the cone gripper, while the cannabis cone is at the second position, is operated to apply a gripping force onto the cannabis cone which is lower than a compacting force reached by the compaction rod between the retraced and extended positions thereof, so that the cannabis cone partly moves in a same direction with the compaction rod along the axis, gradually diminishing the compacting force.
