The present disclosure generally relates to cannabis joints and more specifically to a system for compacting cannabis in a cannabis cone.
Cannabis joints have long been and are still very often prepared by hands.
However, the legalization of cannabis in many territories have seen the coming of the automatization in the manufacturing of cannabis joint.
Some of the automated processes in the manufacturing of cannabis involve inserting paper cones in a cone holding tray and then vibrating the whole tray while it receives cannabis in bulk, the vibrations aiming at evening out the filling of the cones.
A drawback of such vibrating tray is that strong and moderate vibrations have been found to separate the delta-9-tetrahydrocannabinol (THC) from cannabis, thereby decreasing the quality of the product.
Another known automated process for the filling of cannabis includes literally injecting cannabis in each cone and then compacting the cannabis.
Drawbacks of such cannabis injection include separation of THC as described hereinabove and the lack of uniformity along the length of the cone considering its shape.
One of the problems of a machine compacting cannabis in a paper cone while forming a joint is that it is difficult to put enough pressure onto the cannabis to yield an efficient joint while preserving the integrity of the cannabis cone.
According to an illustrative embodiment, there is provided 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; 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.
According to a more specific illustrative embodiment, there is provided 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 the axis;
a cone-raising mechanism for moving the cannabis cone up to a second position along the first 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 applies 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 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, 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.
According to another illustrative embodiment, there is provided a method for compacting cannabis in a cannabis cone having an opening and a bottom, the method comprising:
while holding the cannabis cone:
i) inserting in the opening of the cone an inner protective collar; and
ii) inserting a pusher rod having a tip in the cone through the inner protective collar and moving the pusher rod towards the bottom of the cone until the tip reaches a certain distance from the opening so that the pusher rod.

A first illustrative embodiment of a system 10 for compacting cannabis 14 in a cone 12 (only partly visible in
As will become more apparent upon reading the following description, the system 10 allows compacting a portion of cannabis 14 already filled in a paper cone 12. The product defined by the paper cone 13 being pre-filled with cannabis 14 and that is fed to the system 10 will be referred to as a cannabis cone 16.
The portion of cannabis 14 will also be referred to as a single dose of cannabis 14 and is a predetermined quantity of cannabis provided to form a joint (not shown) with the paper cone 12. Of course, such a single dose 14 may vary depending, for example, on the size of the paper cone 12 to fill.
The paper cone 12 is made, for example, of paper derived from hemp or palm leaves, but can alternatively be made of another material.
With reference briefly more specifically to
Referring to the orientation of the cannabis cone 14 during its compacting by the system 10 and to the compacting method 200, both further described hereinbelow, the tip 18 of the cone 12 will be referred to herein as its bottom, and the base 20 will be referred to as its opened top.
The cannabis cone 16 is an intermediary product in the manufacturing of a cannabis joint (not shown). After the cannabis 14 is compacted in the cone 12 by the system 10, the opened top 20 of the cannabis cone 16 will be closed to form the cannabis joint (not shown).
Prior to be compacted in the cone 12 by the system 10, the cannabis 14 might have been pre-compacted or not.
It is to be noted that the manufacturing steps of the cannabis cone 16 prior and after its compacting is beyond the scope of the illustrative embodiment described herein and will not be described herein in more detail.
Also, since cannabis cones 16 are believed to be well-known in the art, they will not be described herein in more detail for concision purposes.
The compacting system 10 comprises i) a cone holder 24 having a bore 26 for receiving the cannabis cone 16 therein and for holding the cannabis cone 26 in a first position along an axis 28 coaxial with the bore 26, ii) an inverted funnel 30 positioned coaxially to the axis 28 at a distance from the cone holder 24, iii) a cone-rising mechanism 32 for moving the cannabis cone 16 through the inverted funnel 30 up to a second position along the axis 28, iv) a cone gripper 34 that is movable between an open position (see
Each of these parts 24-26, and 30-40 of the system 10 will now be described in more detail.
The cone holder 24 is in the form of an elongated body having a frusto-conical bore 26 therein that is configured and sized to receive a cannabis cone 16 therein in a snugly fit manner so as to prevent the deformation and breakage of a cone 14 therein during the compaction of the cannabis 14 therein.
According to the illustrative embodiment, the cannabis cone holder 24 is one of a series of such holders 24 that are freely mounted in corresponding holes 42 in a carrousel 43. The carrousel 43 is provided to facilitate the consecutive compacting of a plurality of cannabis cones 16. The carrousel 43 is rotatably secured to a table 45 via an electric motor (not shown) or another rotation actuator. Since a carrousel is believed to be well-known in the art, it will not be described herein in more detail for convenience purposes.
According to another embodiment (not shown), the cannabis cone holder 24 is mounted to another support or mechanism than the carrousel 43 that allow receiving and supporting a single cone holder or sequentially a plurality thereof.
The cone holder 24 includes a wider head portion 44, defining a shoulder portion 46 that provides support to the holder 24 when deposited into the hole 42.
The cone holder 24 is not limited to the illustrative embodiment and can take other form allowing to receive and support a cannabis cone 16 in a snugly fit manner.
The inverted funnel 30 includes a frusto-conical bore 48 defining top opening and bottom openings 50 and 52 of the funnel 30. The top opening 50 has a diameter slightly greater than the base 20 of the cannabis cone 16 so as to allow its snugly fit passage therethrough. The bottom opening 52 is wider than the top opening 50, resulting in a shape of the bore 48 that facilitates the rapid passage of the cannabis cone 16 through the funnel 30 from the bottom thereof.
While the funnel 30 is illustrated having an outside shape that is circular, it is not limited to such a shape.
The funnel 30 is secured to a plate portion 54 thereunder via a mounting bracket (not shown) secured on the side of the funnel 30. According to another embodiment (not shown), the funnel 30 is secured to the portion plate 54 from its top side 56.
The plate portion 54 has a generally L-shaped and extends generally parallel to the carrousel 43. The L-shaped plate portion 54 is part of a mounting assembly 58 that allows assembling and relatively positioning the funnel 30, the cone gripper 34 and the compaction mechanism 36. The mounting assembly 58 will be further described hereinbelow.
The cone-rising mechanism 32 includes i) a linear actuator 60, having an output shaft 62, ii) a rod 64 secured to the output shaft 62 at the free end 66 thereof so as to define an extension thereof, iii) a rod course length adjusting assembly 68 for limiting the course of the shaft 62, and therefor of the rod 64, and iv) a rod-guiding sleeve 70 coupled to the course-length adjusting assembly 68.
The rod course length adjusting assembly 68 includes top and bottom parallel mounting caps 72 and 74 that are assembled and distanced by a spacer frame 76, and a mechanical stop 78 that is adjustably mounted to both mounting caps 72-74 therebetween. More specifically, the mechanical stop 78 is mounted to the caps 72-74 via two threaded rods 80 that are fixedly mounted to both caps 72-74 therebetween on diametrically opposite locations.
The mechanical stop 78 is in the form of a narrow plate that includes a first central hole 82 to allow passage for the rod 64 for free reciprocal movement therethrough, and two mounting holes 84, each receiving a respective threaded rod 80 therein. A person skilled in the art will now appreciate that the above-described arrangement allows the slidable movement of the mechanical stop 78 between both caps 72-74 parallel thereto. A pair of nuts 86 is provided to secure the mechanical stop 78 on each threaded rod 80 at a selected position thereon. The spacer frame 76 is configured to allow the afore mentioned slidable movement of the mechanical stop 78.
The rod course length adjusting assembly 68 is secured to the table 45 thereunder via its top cap 72 using fasteners 88. A hole 89 in the table allows passage for the rod 64 therethrough.
The rod-guiding sleeve 70 is in the form of a one-piece body having a bottom cylindrical portion 90 that is sized for snugly fit insertion in the table hole 89, an enlarged portion 92 that extends from the bottom cylindrical portion 90 and that defines a shoulder portion 93 therewith, and a top cylindrical portion 94 that extends from the enlarged portion 92 at a longitudinal side thereof opposite the bottom cylindrical portion 90. The top cylindrical portion 94 includes a housing at the distal end thereof, that receive a cylindrical guide, in the form of a bushing 95, and a seal 97 to prevent cannabis 14 from entering the sleeve 70. The top cap 72 includes a hole (not shown) to receive the bottom cylindrical portion 90 of the sleeve 70 therein in a snugly fit manner. The rod guiding sleeve 70 includes a longitudinal bore to allow passage for the rod 64 though therethrough.
The main body 96 of the linear actuator 60 is secured to the bottom cap 74 thereunder via a mounting plate 98 using fasteners or other fastening means or a mounting assembly. The bottom cap 74 and mounting plate 98 are provided with respective registered holes to allow passage for the output shaft 62 of the linear actuator 60 therethrough.
The rod 64 is secured to the output shaft 62 by a cylindrical coupler 100, which further acts as an impactor. For that reason, a rubber ring 102 is provided about the rod 63 onto the coupler 100.
In operation of the cone raising mechanism 32, the linear actuator 60 is actuated so that both its output shaft 62 and the rod 64 are moved upwardly towards the cone holder 24 in unison. This translation of both the shaft 62 and the rod 64 is stopped when the impactor 100 abuts the mechanical stop 78.
The mechanical stop 78 is so positioned that the movement of the rod 64 stops when the cannabis cone 16 is slided out a predetermined height from the cone holder 24, extending partially out of the inverted funnel 30 from a side thereof opposite the cone raising mechanism 32. Of course, the cone raising mechanism 32 is positioned relative to the cone holder 24 and inverted funnel 30 so that the rod 64 is substantially coaxial with both the cone holder 24 and inverted funnel 30.
While the linear actuator 60 according to the first illustrative embodiment is of the pneumatic type, it can also be of another type, including without limitations hydraulic or electric.
Also, another mechanism or assembly than the rod course length adjusting assembly 68 can be provided to adjust or limit the course of the rod 64.
According to still another illustrative embodiment, the cone raising mechanism 32 is omitted.
The position of the cannabis cone 16 while in the cone holder 24 will be referred to as its first position along the axis 28 and its position after being raised by the rod raising mechanism 32 will be referred to as its second position along the axis 28.
The cone gripper 34 will now be described with references to
The cone gripper 34 is in the form of a well-known pneumatic gripper that is equipped with fingers 104 that are configured with arcuate tapered channels 106 that cooperates to form a frusto-conical opening 108 when the gripper 34 is closed. The opening 108 is configured and sized to substantially complement a cannabis cone 16.
The cone gripper 34 is secured, via its main body 110 to the plate portion 54 of the mounting assembly 58 using a mounting bracket 112. The mounting bracket 112 is configured so that the opening 108 of the cone gripper 34 is coaxial with the axis 28 when in its closed position (see Figure
It results from the frusto-conical shape of the opening 108, which is complementary to the cannabis cone 16, that a minimal pressure is required for the cone gripper 34 to hold the cannabis cone 16. Also, the shape of the opening 108 formed by the gripper 34, when its fingers 104 are closed, being complementary to the cannabis cone 16, contributes to stabilize the cone 16 when it is compacted by the compaction mechanism 36 and minimized strain thereon and hence its damaging.
While the gripper 34 has been described as being of the pneumatic type, it can also be of another type, including without limitations hydraulic or electric.
Also, the fingers 104 are limited to the above-described configuration.
The compaction mechanism 36 will now be described in more detail with references to
The compaction mechanism 36 comprises a linear actuator 114 that is secured to the mounting assembly 58 via a position-adjustment mechanism 116 which allows adjusting the position of its output shaft 118 along the axis 28.
According to another illustrative embodiment, such a position-adjustment mechanism 116 is omitted and the linear actuator 114 is fixedly positioned relatively to the neutral position of the cone holder 24 via the mounting assembly 58 or else.
The compaction rod 38 is secured to the output shaft 118, coaxially thereto, using a conventional cylindrical coupler 120. The length of the rod 38, the position of the compaction mechanism 36 relative to the second position of the cannabis cone 16 along the compacting axis 28, and the configuration of the linear actuator 114 are such that the rod 38 can reciprocate along the axis 28 between a retracted position, wherein the tip 122 of the rod 38 is out of the cannabis cone 16 while at the second position (see for example in
According to the first illustrative embodiment, the linear actuator 114 if of the pneumatic type, but it can alternatively be of another type, including without limitations hydraulic or electric. For example, the use of an electric actuator allows a more precise control of the insertion distance of the rod 38 in the cannabis cone 16 during compaction.
To prevent the compaction rod 38 from touching the paper cone 12 during its reciprocating movement therein, an expandable collar 40 is provided that is movable when the compaction rod 38 moves from the retracted position to the extended position. The expandable collar 40 is thus movable between a compact position in the cannabis cone 16 (see
With reference to
The expandable collar 40 comprises a clamp 124 including three (3) jaws 126 pivotably mounted to a mounting body 128 for pivotal movement between close and open position (see
According to the first illustrative embodiment, the mounting body 128 includes a small triangular attaching portion 133 that is secured to the plate portion 54 of the mounting assembly 58 using fasteners 131 and a cylindrical connecting portion 134 extending upwardly from the attaching portion 132. The mounting body 128 further includes a circular hole 135 that is coaxial with the compacting axis 28.
The rod support member 132 includes a holding ring 136 that includes a narrow connecting portion 138 for coupling with the cylindrical connecting portion 134 therein. Both the narrow holding ring 138 and cylindrical connecting portion 134 are configured for complementary attachment, for example by clipping or screwing. A guiding sleeve 140 in the form of a bushing is inserted in the cylindrical member 136. The sleeve 140 is configured for snugly-fit insertion in the cylindrical member 136 and to allow passage for the rod 38 therethrough in a snuggly fit manner.
Each jaw 126 of the clamps 124 includes a mounting portion 142 and a thin arcuate finger portion 144 extending therefrom.
The mounting portion 142 is in the form of a generally rectangular body having top and bottom sides 146 and 148, two lateral sides 150, and outer and inner sides 152 and 154.
Each jaw 126 of the clamps 124 includes a support portion 142 and a thin arcuate finger 144 extending therefrom.
Each mounting portion 142 is pivotably mounted to the triangular attaching portion 128, between two adjacent sides thereof via a pivot pin 156, so as to be freely movable between first and second positions, corresponding respectively to a closed configuration of the clamp 124 (see
Each mounting portion 142 further includes an arcuate notch 158. These notches 158 define housings that receive the rubber ring 130. The ring 130, which can alternatively be made of another resilient material, such as an elastomer, is configured and sized to bias the three jaws 126 towards their first position. According to another illustrative embodiment (not shown), the biasing member can be in the form of springs between each jaw 126 and the mounting portion 142.
Each thin arcuate finger 144 is secured to the support portion on the inner side 154 thereof so as to extend along the inner side 154 and further beyond the bottom side 148. This configuration of the fingers 144 yields a cylindrical opening 160 that allows complementary receiving the rod 38 when the clamp 124 is in the open configuration. Each jaw 126 further includes tapered lateral wings 162 on both lateral sides 150 of the body 142 adjacent the finger 144.
According to another illustrative embodiment (not shown), the fingers 144 or more generally the jaws 126 are configured differently than illustrated. Also, the pivotal mounting of the jaws 126 may be different than illustrated and so is the biasing member to force the jaws 126 in a compact configuration.
Further details on the expandable collar 40 and operation thereof will now be described in more detail while describing the operation of the system 10 for compacting cannabis cone 16 with references to
While the expandable collar 40 in this configuration, the cannabis cone 16 is raised by the cone-rising mechanism 32, and moved through the inverted funnel 30, until the wide opening 20 of the cannabis cone 16 surrounds the lower portion of the fingers 144 (see
Then the gripper 34 is moved into its closed position, holding the cannabis cone 16 at its second position (see
While the cannabis cone 16 is held by the gripper 34, the arcuate fingers 144 are forced towards their second positions by the insertion of the rod 38 therethrough causing the clamp 124 to open under the passage of the rod 38, yielding a protective collar between the rod 38 and the top opening 20 of the paper cone 12 (
With reference to
At one point during the downward movement of the compaction rod 38, the cannabis 14 in the cannabis cone 16 reaches such a level of compaction that the downward force of the rod 38 is greater than the gipping force applied by the gripper 34 onto the cone 16, forcing the cone 16 to move downwardly with rod 38 (see
The system 10 can further be operated so that the following, for example, can be adapted to yield a final product having different characteristics:
It is to be noted that all the actuators described hereinabove are connected to one or more controllers (not shown) so that their operations are triggered and synchronized thereby. All the connectors between such controller(s) and the actuators have been omitted in the drawings so as to alleviate the views.
It is to be noted that many modifications could be made to the cannabis joints compacting system 10 and method 200 described hereinabove and illustrated in the appended drawings. For example:
Although a system and method for compacting cannabis in a cannabis cone have been described hereinabove by way of illustrated embodiments thereof, they can be modified. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that the scope of the claims should not be limited by the preferred embodiment but should be given the broadest interpretation consistent with the description as a whole.
