Definitions
- the invention generally relates to systems for medicinal and recreational cannabis harvesting.
- the present invention relates to systems for separating medicinal and recreational cannabis stems from leaves and buds.
- Cannabis plants are now commonly grown to facilitate the increasing demand for medicinal and recreational cannabis products.
- the legalization of cannabis has increased the demand for higher quality cannabis products at regulated prices. Therefore, farmers and growers are seeking solutions to increase harvest efficiency while maintaining quality.
- the growing and harvesting of cannabis plants is a multi-step process that was traditionally performed entirely by hand.
- Cannabis plants grow in a bush-like configuration, including a plurality of intertwined stems with leaves and buds.
- the stems of the plant contain less than desirable amounts of the cannabis components. Therefore, one of the primary steps in harvesting cannabis plants is separating the desirable leaves and buds from the undesirable stems.
- Conventional manual processes for the separating step include holding the stem with one hand while simultaneously pulling off the leaves and buds with the opposite hand or cutting the buds from the stem with scissors.
- Cannabis stems may include a wide variety of diameters depending on the size of the plant and proximity to the roots.
- different types or strains of Cannabis may include different strengths such as stem deformation, leaf bonding, bud bonding, etc.
- GB 2 290 694 discloses process and apparatus for separating tobacco leaf blades from the leaf stems, and subsequently cutting up the stems to desired lengths.
- the present invention relates to systems for separating cannabis stems from leaves and buds according to claim 1.
- Embodiments of the present invention represent a significant advance in the field of cannabis stem harvesting.
- Conventional manual cannabis harvesting techniques are extremely inefficient and inconsistent.
- Conventional automatic vine harvesting systems from other fields are ineffective for cannabis because of the unique stem structure of the plant versus the stalk structure of other plants such as tobacco.
- Embodiments of the present invention provide multiple orifices or channels through which a user can insert the cannabis stem which includes the desirable leaves and buds.
- the stems of the cannabis plant may have different thicknesses depending on various factors and therefore a single orifice stripper will not properly harvest cannabis leaves and buds.
- the present invention relates to systems for separating cannabis stems from leaves and buds.
- An example method for separating cannabis stems from leaves and buds have also been included to aid understanding of the invention and does not form part of the claim scope.
- One embodiment of the present invention relates to a system for cannabis stem harvesting configured to specifically separate the leaves and buds from the stem.
- the system includes a frame member, a die member, first rotating cylindrical member, second rotating cylindrical member, and a rotation system.
- the die member is coupled to the frame member and includes a plurality of orifices disposed within a single layer plate.
- the first and second rotating cylindrical members are coupled to the frame member in a vertical configuration and oriented substantially adjacent to the die member.
- the vertical configuration of the first and second rotating cylindrical members defines a pinch region therebetween as a region across which a first and second circumferential surface of the first and second rotating cylindrical members are closest in proximity.
- the rotation system is coupled to the frame member and at least one of the first and second rotating members.
- Cannabis - a particular plant family including various strains or varieties intended for both medicinal and recreational purposes. All cannabis plants grow in a bush-like
- Rotating cylindrical member - a member that has a cylindrical shape including a curved circumferential surface between two ends.
- the member is also configured to rotate about an axis which extends between the two ends. Therefore, two dimensional linear regions of the circumferential surface between the ends rotate in a radial manner around an axis which extends through the ends.
- Durometer a measurement of material hardness wherein a lower durometer relates to a lower degree of hardness and a higher durometer relates to a higher degree of hardness.
- steel has a high durometer while foam has a low durometer.
- Die member - a single layer plate which may contain a plurality of holes, dies, or orifices.
- Pinch region - a two dimensional region between two substantially adjacent cylindrical rotating members.
- the pinch region is the linear region across which the two cylindrical rotating members are in closest proximity.
- the pinch region may also be defined as a location between two radial positions of the two circumferential surfaces at which the circumferential surfaces are in closest proximity.
- the vine stripping apparatus 10 comprises a support frame 20, two counter-rotating wheels 22 and 24, a vine stripper 26, and wheel rotating means 28 and 30.
- the support frame 20 comprises a structure for supporting the counter-rotating wheels 22, 24.
- a preferred embodiment of the support frame is shown in FIGs. 1 through 3 , 9 and 10 .
- the support frame consists of a first support rail 32 and a second support rail 34, wherein the first and second support rails are substantially parallel to one another.
- the support frame is substantially vertically oriented.
- the support frame may be positioned in any orientation that is convenient for the particular application. It is further contemplated that the support frame may be configured in any number of ways, so long as the support frame is adapted to receive the counter-rotating wheels in the relative position as described herein.
- a pair of counter-rotating wheels are mounted on the support frame 20.
- the counter-rotating wheels include a first wheel 22 having a first lateral surface 22a, and a second wheel 24 having a second lateral surface 24a.
- the counter-rotating wheels comprise pneumatic (inflatable) tires, such as conventional automotive tires, mounted on conventional automotive wheels.
- Conventional automotive tires and wheels, as shown in the drawings, are especially suitable for carrying out the invention because the pressure in the tires can be adjusted to an optimum level.
- any wheel having a pliable lateral surface could be used in place of the automotive tire and wheel as described and shown herein, and is considered to be within the scope of the invention.
- at least one of the wheels has a pliable lateral surface.
- the first wheel 22 and the second wheel 24 are rotatably secured to the support frame 20 on a first axle 36 and a second axle 42, respectively.
- the first axle has a first end 38 and a second end 40.
- the second axle has a first end 44 and a second end 46.
- Each axle first end is rotatably secured to the first support rail 32 of the support frame.
- Each axle second end is functionally engaged with the wheel rotating means 28, 30 mounted on the second rail 34 of the support frame.
- the first axle and the second axle are parallel to and spaced apart from one another, such that the lateral surfaces 22a, 24a of the counter-rotating wheels are compressed against one another in substantially full contact with one another, as shown in FIGs. 2 , 3 and 4 .
- the counter-rotating wheels grip the vine to be stripped, and provide pulling force to draw the vine through the vine stripper 26 as the wheels are rotated at relatively high speed.
- the grip on the vine must be secure and not disposed to slipping or crushing the vine.
- Pneumatic tires are uniquely suited to this purpose because the pressure in the tires, and thus the gripping force, is adjustable by simply increasing or decreasing the pressure in the tires. At the appropriate tire pressure, the surface of the pneumatic tires will conform to accommodate the shape of the vine while gripping it securely as pulling force is applied and plant material is stripped away by the vine stripper.
- Pneumatic tires inflated to about 30 to 45 psi have been found to be most effective in carrying out the invention.
- the vine stripper 26 is affixed to the support frame 20, although this is not a requirement of the invention.
- a freestanding or alternative support for the vine stripper may also be employed.
- the vine stripper comprises at least one stripping orifice 50.
- the stripping orifice receives an end of the vine to be stripped, and is the point at which the plant material is removed from the vine during the operation of the vine stripping apparatus.
- the stripping orifice is formed in a stripping orifice plate 48..
- the stripping orifice has a blunt, substantially planar stripping edge 51. The inventors have found that the blunt edge allows the plant material to be removed from the vine without inadvertently severing the vine. In operation, vines are pulled very quickly through the stripping orifice by the counter-rotating wheels, and in the process tend to wave and move about.
- the vines are bulky, rope-like, and
- FIGs. 4 and 8 show a side view of the stripping orifice 50; in these figures it can be seen that the stripping edge 51 is substantially planar and does not protrude outwardly from the stripping orifice.
- the substantially flush stripping edge eliminates another potential cause of vine breakage when the vine stripping apparatus is in use.
- a protruding point or notch in the stripping orifice is more likely to catch the vine and cause it to be severed by the stripping orifice.
- the flush stripping orifice is also a significant safety feature of the present invention.
- the vine stripping apparatus may be mounted on a mobile harvesting unit.
- the stripping orifice is large enough to allow a vine and support twine to pass through, but small enough to prevent the passage of the majority of leaves and other plant material, such as hops.
- the stripping orifice is also sized to prevent the operator's hand from inadvertently being pulled through.
- the stripping orifice 50 is positioned between the first axle 36 and the second axle 44, centered proximate a contact point 52 where the first lateral surface 22a of first wheel 22 and the second second lateral surface 24a of second wheel 24 contact one another.
- the stripping orifice is located in close proximity to the contact point 52, as best seen in FIG. 4 .
- the wheels are approximately 24 inches (0.6096 meters) in diameter and approximately 8 1 ⁇ 2 inches (0.2159 meters) in width
- placement of the stripping orifice approximately 6 inches (0.1524 meters) from the contact point is ideal. The inventors have found that the placement of the stripping orifice near the contact point minimizes the likelihood that the vine will break during the stripping operation, and allows the vine stripping apparatus to be operated at higher speeds.
- the stripping orifice 50 comprises a threaded opening 54 in the stripping orifice plate 48, and a complementary threaded stripping die 56 having a substantially cylindrical body receivable in the threaded opening.
- a complementary threaded stripping die 56 having a substantially cylindrical body receivable in the threaded opening.
- several interchangeable stripping dies such as the ones shown in FIGs. 5, 6 and 7 and 8 , can be employed.
- the stripping orifice comprises an opening in the stripping orifice plate 48 and a channel affixed on the stripping orifice plate for slidably receiving a stripping die having a substantially planar rectangular body.
- the size and configuration of the stripping orifice can be matched to the particular species or variety of plant being harvested. It has been found that certain shapes are more effective at catching and removing plant material from a vine as it pulled through the stripping orifice 50.
- the circular opening 58 of the threaded stripping die shown in FIG. 5 , and the "star" shaped openings 60 and 62 of the threaded stripping dies shown in FIGs. 6 and 7 have been used with success with hop vines.
- the star shape has been found to be especially effective in removing plant material, due to the multiple "notches" created by the points of the star.
- first wheel 22 and second wheel 24 The purpose of the counter-rotating wheels, first wheel 22 and second wheel 24, is to grasp and pull the vine and twine through the stripping orifice 50.
- first wheel 22 is rotated in a first direction Ri
- second wheel 24 is rotated in a second direction R 2 , opposite the first direction.
- the counter-rotation of the wheels is best shown in FIG. 4 , wherein it can be seen that the first wheel is rotated in a counterclockwise direction, and the second wheel is rotated in a clockwise direction.
- the result of the counter-rotational relationship of the wheels is that at the contact point 52, both wheels are rotating in a direction away from the stripping orifice 50.
- the rotating means 28 and 30 shown in FIGs. 1 through 4 provide power to effect the rotation of the wheels 22, 24 as described above.
- the rotating means are hydraulic motors, although other types of power sources are contemplated, including electric power, combustible fuel, and manual power.
- the vine stripping apparatus 10 further includes a cowling 64, which provides a safety barrier to protect the operator from the rotating wheels 22, 24.
- the vine stripping apparatus 10 In use, the vine stripping apparatus 10 rapidly and thoroughly removes substantially all plant material 66 from a vine and deposits it in a collection location 68, and ejects the stripped vine 70 in a disposal location 72. See FIGs. 4 and 9 .
- the process of stripping a vine using the vine stripping apparatus described herein includes first obtaining an unstripped vine 74 that has been severed from its root.
- an "unstripped vine” is a vine that has not been stripped of leaves and other plant material, and may or may not include the support twine on which the vine was grown. In the case of hop vines, both the root end and trellis end of the vine and twine must be severed, leaving a completely detached unstripped vine.
- the wheel rotating means 28, 30 are engaged to turn first wheel 22 in direction Ri and second wheel 24 in direction R 2 .
- the root end 76 of the unstripped vine is inserted into the stripping orifice 50 until it reaches the wheel contact point 52.
- the root end of the unstripped vine is grasped between the wheels and the vine is pulled through the stripping orifice.
- Plant material 66 growing on the vine is too bulky to pass through the stripping orifice, and is therefore pulled off of the vine by the stripping orifice and deposited in the collection location 68.
- the stripping process occurs rapidly - under ideal conditions, approximately thirty 18-foot vines can be stripped per minute.
- An advantage of the process described herein is that nearly all of the plant material 66 is removed from the vine, resulting in very little waste.
- An additional advantage of the process is that the plant material sustains very little damage during this stripping process. This is due to the "self-cushioning" effect that results as the vine passes through the stripping orifice 50. The plant material tends to accumulate against the stripping orifice, forming a cushion against which additional plant material is pressed as the vine is pulled through.
- At least one vine stripping apparatus 10 is mounted to a mobile harvesting unit 78 suitable for use in the field where the crop to be harvested is grown.
- the mobile harvesting unit is used in combination with a receptacle 80 for collecting the harvested plant material 66 and transporting it to a central processing facility for further sorting and processing.
- the mobile harvesting unit may be adapted to be towed by another powered vehicle, as shown in FIGs. 9 and 10 , or it may include an integrated power source for moving through the field.
- the mobile harvesting unit or the powered vehicle may include a power source for providing power to the rotating means 28, 30 of the vine stripping apparatus.
- the mobile harvesting unit 78 is adapted to receive one or more vine stripping apparatuses, as shown generally in FIGs. 9 and 10 .
- a conveyor 82 is provided in the bed of the vehicle for receiving the plant material 66 and carrying it to be deposited in the receptacle 80.
- Each vine stripping apparatus 10 is positioned on the vehicle so that the vine stripper 26 is substantially oriented toward the conveyor.
- An operator platform 84 in the vehicle provides a secure location for the operator to stand as he or she feeds unstripped vines 74 into the vine stripping apparatus 10.
- FIG 11 illustrates a general process of separating a cannabis plant stem from cannabis leaves and buds using a system designated generally at 300.
- the system 300 will be described in more detail with reference to Figures 12-14 .
- the illustrated process begins with the act of providing a cannabis plant 350 including both a stem 354 and a plurality of leaves and buds 352, designated generally at 310.
- the cannabis plant 350 may be any type of cannabis including various varieties, strains, growing techniques, stages of harvest, etc.
- the cannabis plant 350 may be either in a wet or dry state depending on whether a pre-harvesting drying act was performed prior to stem harvesting.
- a user selects and orients the stem 354 with an orifice or die on a harvesting system 300, designated generally at 320.
- the act of selecting the orifice to correspond to the stem 354 includes selecting an orifice with a diameter that substantially corresponds to the diameter of the stem 354. The more closely the diameter of the orifice corresponds to the stem diameter, the more efficient the operation of the stem harvesting process and system.
- the system 300 separates the stems 354 from the leaves and buds 352 as represented by the independent acts 340 and 330.
- the illustrated implementation shows the leaves and buds 352 being directed into a bin directly below the orifices while the stems are routed to a second depository (not shown) behind the orifices.
- FIG 12A-B illustrate views of a cannabis stem harvesting system, designated generally at 400.
- the system includes a frame member 420, die member 430, first rotating cylindrical member 460, a second rotating cylindrical member 480, rotation system, and a pinch region 490.
- the illustrated frame member 420 includes a rigid structural support frames and structures.
- the frame member 420 may comprise a metal material including but not limited to aluminum or steel.
- the illustrated frame member 420 includes four castor wheels to enable translation of the system 400.
- the frame member 420 further includes various shielding panels to isolate and protect a user from the first and second cylindrical rotating members 460, 480.
- the shielding panels in the illustrated embodiment include a top and bottom cowling 422.
- the frame member 420 may further include one or more receptacles for receiving plant material.
- two harvest bins 424 are disposed below the die member 430 on the user side which is opposite the first and second cylindrical rotating members 460, 480.
- the harvest bins 424 are configured to receive the plant leaves and buds as shown in Figure 11 .
- a second set of stem bins or receptacles may be included to catch the separated stems as shown in Figure 11 .
- Various other equipment may be incorporated into the process including but not limited to conveyors for transporting buds and leaves.
- the frame member 420 is coupled to both the die member 430 and the first and second cylindrical rotating members 460, 480 so as to orient them as shown.
- first and second cylindrical rotating members 460, 480 are oriented in a substantially vertical or stacked configuration in which the first cylindrical rotating member 460 is positioned above the second cylindrical rotating member 480.
- the orientation or configuration further includes orienting the first and second cylindrical rotating members in a substantially parallel horizontal and depth alignment.
- substantially vertical, horizontal, and depth are used in accordance with the visual representations shown in Figures 12A-B .
- the die member 430 is a single layer panel including a plate 432 and a plurality of orifices 434 disposed on the plate.
- the plate 432 shown in the illustrated embodiment is vertically concave with respect to the user.
- the purpose of the concave surface is to position the plurality of orifices 434 close (in proximity) to the first and second cylindrical rotating members 460, 480 while maintaining the shielding and isolation of the user necessary for safety.
- Alternative system embodiments discussed below will illustrate other techniques for disposing the orifices 434 in close proximity to the first and second cylindrical rotating members 460, 480 without a concave plate 432.
- the plurality of orifices 434 include at least two holes having different diameters.
- the plurality of orifices 434 are oriented on the plate 432 horizontally in a manner such that each of the orifices are substantially equidistant to the first and second cylindrical rotating members 460, 480.
- the orifices 434 may each include shapes that are circular or non-circular to accommodate various stripping properties.
- the orifices 434 inherently form an edge at the junction with the plate 432.
- the thickness and composition of the plate 432 will affect the stripping characteristics of the orifices 434.
- the edge may be orthogonal, ramped, or curved so as to further affect the stripping characteristics of the system. Extensive testing with respect to cannabis has resulted in maximum and minimum sizing of the orifices 434 between one quarter inch and two inches (0.12954 and 0.0508 meters).
- the first and second cylindrical rotating members 460, 480 are cylindrically shaped members including a first and second circumferential surface 462, 482 and a first and second axle 464, 484 respectively.
- the first and second circumferential surfaces 462, 482 are curved radial surfaces which encircle the first and second cylindrical rotating members 460, 480 and are between two ends as shown.
- the length of the first and second circumferential surfaces 462, 482 is based on the diameter of cylindrical rotating member and/or the ends. Extensive testing with respect to cannabis has resulted in a maximum and minimum diameter sizing of the cylindrical members 460, 480 between three and twelve inches (0.0762 - 0.3048 meters).
- first and second circumferential surfaces 462, 482 may include a raised gripping pattern (not shown) such as a tread (i.e. tire), plurality of ribs (i.e. gear), and/or any other pattern of raised regions.
- first and second cylindrical rotating members 460, 480 may include various material compositions of a particular durometer, which may result in a deformation in the first and second circumferential surfaces 462, 482 across particular regions under certain circumstances.
- the durometer of the members may be based on an internal air pressure (i.e. tire), material composition (i.e. rubber, steel, plastic), and/or other variables.
- the first and second cylindrical rotating members 460, 480 are configured to rotate about the first and second axles 464, 484.
- the rotation includes translating the first and second circumferential surfaces 462, 482 in a radial manner such that a single point on a circumferential surface may translate in a substantially circular orbit around the respective axle.
- the rotation may further include an opposite rotation of each of the circumferential surfaces including the first circumferential surface 462 rotating in a counter-clockwise orbit and the second circumferential surface rotating in a clockwise orbit with respect to the perspective shown in Figures 12A-B .
- This opposite rotation causes a pulling force to be exerted on an object positioned between the first and second circumferential surface. The pulling force is directed away from the die member 430.
- At least one of the first and second cylindrical rotating members 460, 480 is further coupled to a rotation system configured to enable automatic rotation of the cylindrical rotating members 460, 480 in the manner described above.
- the rotation system may be directly coupled to one or both of the cylindrical rotating members 460, 490.
- the rotation system is not illustrated in the embodiment shown in Figures 12A-B but will be illustrated in more detail with reference to the figures below.
- the rotation system may be configured to rotate the first and second cylindrical rotating members 460, 480 at a variable selective speed/rate to accommodate different harvesting characteristics, , plant strains, and/or other unique plant characteristics.
- variable selective rotation speed of the first and second cylindrical rotating members 460, 480 must produce a feed rate between 10 and 250 feet per minute (0.0508 to 1.27 meters per second), .
- a slower feed rate is desirable for dry stripping processes so as to minimize damage to the leaves and buds.
- a faster feed rate is desirable for wet stripping so as to optimize processing.
- This feed rate corresponds to approximately 188 revolutions per minute for a cylindrical member having a six inch diameter (0.1524 meters).
- the rotation system may further include a motor, power source, and user selection mechanism.
- the pinch region 490 is a region of closest proximity between the first and second circumferential surfaces 462, 482 of the first and second cylindrical rotating members 460, 480.
- the alignment of the cylindrical rotating members 460, 480 discussed above causes the pinch region to be a region between the circumferential surfaces 462, 482 that is vertically aligned with the axles 464, 484 as shown in Figure 12B .
- the pinch region 490 extends across the circumferential surfaces 462, 482 at a particular radial location. It will therefore be appreciated that the illustrated horizontal alignment of the orifices 434 discussed above further achieves a consistent alignment and spacing with the pinch region 490 in the illustrated embodiment.
- the pinch region 490 may include a coupling between the first and second circumferential surfaces 462, 482 or a proximity under two inches (0.0508 meters). Variables pertaining to the pinch region 490 are critical for the safe and efficient operation of the system 400. The distance to the pinch region 492 from the orifices 434 is also a critical measurement in the operation of the overall system 400. Extensive testing has concluded that the distance to the pinch region 492 must be under six inches (0.1524 meters) to function properly for harvesting of cannabis with an optimal value of approximately two inches (0.0508 meters). This discovery is in contrast to the operation of conventional stripping systems which were adapted for stalk type plants such as a tobacco. For at least this reason, conventional systems cannot be adapted to function for cannabis without significant inefficiencies or diminished user safety.

Description
- The invention generally relates to systems for medicinal and recreational cannabis harvesting. In particular, the present invention relates to systems for separating medicinal and recreational cannabis stems from leaves and buds.
- Cannabis plants are now commonly grown to facilitate the increasing demand for medicinal and recreational cannabis products. The legalization of cannabis has increased the demand for higher quality cannabis products at regulated prices. Therefore, farmers and growers are seeking solutions to increase harvest efficiency while maintaining quality. The growing and harvesting of cannabis plants is a multi-step process that was traditionally performed entirely by hand.
- Cannabis plants grow in a bush-like configuration, including a plurality of intertwined stems with leaves and buds. The stems of the plant contain less than desirable amounts of the cannabis components. Therefore, one of the primary steps in harvesting cannabis plants is separating the desirable leaves and buds from the undesirable stems. Conventional manual processes for the separating step include holding the stem with one hand while simultaneously pulling off the leaves and buds with the opposite hand or cutting the buds from the stem with scissors. There are many challenges in removing the leaves and buds from the stems. For example, Cannabis stems may include a wide variety of diameters depending on the size of the plant and proximity to the roots. Likewise, different types or strains of Cannabis may include different strengths such as stem deformation, leaf bonding, bud bonding, etc.
- Various automated stem-leaf separation processes have been attempted for cannabis separation. These processes include attempts at repurposing harvesting equipment from other crops to use with cannabis. Unfortunately, these attempts at automated cannabis stem-leaf separation processes have failed to accurately and/or efficiently strip the leaves and buds from the vine without significant loss, yield inefficiencies, location constraints, and/or danger to operators. Cannabis plants are very different from other plants, and conventional harvesting equipment cannot successfully be repurposed without significant modification.
- Therefore, there is a need in the industry for an improved method and apparatus of cannabis stem separation from leaves and buds.
GB 2 290 694 - The present invention relates to systems for separating cannabis stems from leaves and buds according to claim 1.
- Embodiments of the present invention represent a significant advance in the field of cannabis stem harvesting. Conventional manual cannabis harvesting techniques are extremely inefficient and inconsistent. Conventional automatic vine harvesting systems from other fields are ineffective for cannabis because of the unique stem structure of the plant versus the stalk structure of other plants such as tobacco. Embodiments of the present invention provide multiple orifices or channels through which a user can insert the cannabis stem which includes the desirable leaves and buds. The stems of the cannabis plant may have different thicknesses depending on various factors and therefore a single orifice stripper will not properly harvest cannabis leaves and buds.
- These and other features and advantages of the present invention will be set forth or will become more fully apparent in the description that follows and in the appended claims. The features and advantages may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Furthermore, the features and advantages of the invention may be learned by the practice of the invention or will be obvious from the description, as set forth hereinafter.
- The following description of the invention can be understood in light of the Figures, which illustrate specific aspects of the invention and are a part of the specification. Together with the following description, the Figures demonstrate and explain the principles of the invention. In the Figures, the physical dimensions may be exaggerated for clarity. The same reference numerals in different drawings represent the same element, and thus their descriptions will be omitted.

An example method for separating cannabis stems from leaves and buds have also been included to aid understanding of the invention and does not form part of the claim scope. One embodiment of the present invention relates to a system for cannabis stem harvesting configured to specifically separate the leaves and buds from the stem. The system includes a frame member, a die member, first rotating cylindrical member, second rotating cylindrical member, and a rotation system. The die member is coupled to the frame member and includes a plurality of orifices disposed within a single layer plate. The first and second rotating cylindrical members are coupled to the frame member in a vertical configuration and oriented substantially adjacent to the die member. The vertical configuration of the first and second rotating cylindrical members defines a pinch region therebetween as a region across which a first and second circumferential surface of the first and second rotating cylindrical members are closest in proximity. The rotation system is coupled to the frame member and at least one of the first and second rotating members. An exemplary method of separating the stem from the leaves and buds of a cannabis plant, including the acts of aligning the plant with an orifice, inserting the stem of the plant into the orifice, pulling the plant through the orifice, and stripping the leaves and buds from the stem using the system is also provided. Also, while embodiments are described in reference to a system for cannabis stem harvesting, it will be appreciated that the teachings of the present invention are applicable to other areas of cannabis harvesting.
- The following terms are defined as follows:
- Cannabis - a particular plant family including various strains or varieties intended for both medicinal and recreational purposes. All cannabis plants grow in a bush-like
- Rotating cylindrical member - a member that has a cylindrical shape including a curved circumferential surface between two ends. The member is also configured to rotate about an axis which extends between the two ends. Therefore, two dimensional linear regions of the circumferential surface between the ends rotate in a radial manner around an axis which extends through the ends.
- Durometer - a measurement of material hardness wherein a lower durometer relates to a lower degree of hardness and a higher durometer relates to a higher degree of hardness. For example, steel has a high durometer while foam has a low durometer.
- Die member - a single layer plate which may contain a plurality of holes, dies, or orifices.
- Pinch region - a two dimensional region between two substantially adjacent cylindrical rotating members. The pinch region is the linear region across which the two cylindrical rotating members are in closest proximity. The pinch region may also be defined as a location between two radial positions of the two circumferential surfaces at which the circumferential surfaces are in closest proximity.
- With reference to
FIGs. 1 and2 , thevine stripping apparatus 10 comprises asupport frame 20, twocounter-rotating wheels vine stripper 26, and wheel rotatingmeans - The
support frame 20 comprises a structure for supporting thecounter-rotating wheels FIGs. 1 through 3 ,9 and10 . In this embodiment, the support frame consists of afirst support rail 32 and asecond support rail 34, wherein the first and second support rails are substantially parallel to one another. In the embodiment shown in the drawings, the support frame is substantially vertically oriented. However, it is contemplated that the support frame may be positioned in any orientation that is convenient for the particular application. It is further contemplated that the support frame may be configured in any number of ways, so long as the support frame is adapted to receive the counter-rotating wheels in the relative position as described herein. - A pair of counter-rotating wheels are mounted on the
support frame 20. In the preferred embodiment shown in the drawings, the counter-rotating wheels include afirst wheel 22 having a first lateral surface 22a, and asecond wheel 24 having a secondlateral surface 24a. In a preferred embodiment, the counter-rotating wheels comprise pneumatic (inflatable) tires, such as conventional automotive tires, mounted on conventional automotive wheels. Conventional automotive tires and wheels, as shown in the drawings, are especially suitable for carrying out the invention because the pressure in the tires can be adjusted to an optimum level. However, any wheel having a pliable lateral surface could be used in place of the automotive tire and wheel as described and shown herein, and is considered to be within the scope of the invention. According to the invention, at least one of the wheels has a pliable lateral surface. - The
first wheel 22 and thesecond wheel 24 are rotatably secured to thesupport frame 20 on afirst axle 36 and asecond axle 42, respectively. The first axle has afirst end 38 and asecond end 40. The second axle has afirst end 44 and asecond end 46. Each axle first end is rotatably secured to thefirst support rail 32 of the support frame. Each axle second end is functionally engaged with thewheel rotating means second rail 34 of the support frame. The first axle and the second axle are parallel to and spaced apart from one another, such that thelateral surfaces 22a, 24a of the counter-rotating wheels are compressed against one another in substantially full contact with one another, as shown inFIGs. 2 ,3 and4 . It has been found by the inventors that the compression of the counter-rotating wheels against one another is critical to the function of the vine stripping apparatus. As will be described more fully below, the counter-rotating wheels grip the vine to be stripped, and provide pulling force to draw the vine through thevine stripper 26 as the wheels are rotated at relatively high speed. The grip on the vine must be secure and not disposed to slipping or crushing the vine. Pneumatic tires are uniquely suited to this purpose because the pressure in the tires, and thus the gripping force, is adjustable by simply increasing or decreasing the pressure in the tires. At the appropriate tire pressure, the surface of the pneumatic tires will conform to accommodate the shape of the vine while gripping it securely as pulling force is applied and plant material is stripped away by the vine stripper. Pneumatic tires inflated to about 30 to 45 psi have been found to be most effective in carrying out the invention. - In a preferred embodiment, the
vine stripper 26 is affixed to thesupport frame 20, although this is not a requirement of the invention. A freestanding or alternative support for the vine stripper may also be employed. The vine stripper comprises at least one strippingorifice 50. The stripping orifice receives an end of the vine to be stripped, and is the point at which the plant material is removed from the vine during the operation of the vine stripping apparatus. In a preferred embodiment, the stripping orifice is formed in a strippingorifice plate 48.. The stripping orifice has a blunt, substantially planar strippingedge 51. The inventors have found that the blunt edge allows the plant material to be removed from the vine without inadvertently severing the vine. In operation, vines are pulled very quickly through the stripping orifice by the counter-rotating wheels, and in the process tend to wave and move about. The vines are bulky, rope-like, and - somewhat unwieldy. A sharp stripping edge would certainly sever the vine, and would therefore be unworkable for the present invention.
-
FIGs. 4 and8 show a side view of the strippingorifice 50; in these figures it can be seen that the strippingedge 51 is substantially planar and does not protrude outwardly from the stripping orifice. This feature adds both functionality and safety to the invention design. The substantially flush stripping edge eliminates another potential cause of vine breakage when the vine stripping apparatus is in use. A protruding point or notch in the stripping orifice is more likely to catch the vine and cause it to be severed by the stripping orifice. The flush stripping orifice is also a significant safety feature of the present invention. In use, the vine stripping apparatus may be mounted on a mobile harvesting unit. An operator rides on the mobile harvesting unit and feeds vines into the vine stripping apparatus while the unit is in motion. A protruding blade or teeth on the stripping orifice would surely lead to operator injury. The stripping orifice is large enough to allow a vine and support twine to pass through, but small enough to prevent the passage of the majority of leaves and other plant material, such as hops. The stripping orifice is also sized to prevent the operator's hand from inadvertently being pulled through. - As shown in
FIGs. 1 ,2 and4 , the strippingorifice 50 is positioned between thefirst axle 36 and thesecond axle 44, centered proximate acontact point 52 where the first lateral surface 22a offirst wheel 22 and the second secondlateral surface 24a ofsecond wheel 24 contact one another. Preferably, the stripping orifice is located in close proximity to thecontact point 52, as best seen inFIG. 4 . In an embodiment in which the wheels are approximately 24 inches (0.6096 meters) in diameter and approximately 8 ½ inches (0.2159 meters) in width, placement of the stripping orifice approximately 6 inches (0.1524 meters) from the contact point is ideal. The inventors have found that the placement of the stripping orifice near the contact point minimizes the likelihood that the vine will break during the stripping operation, and allows the vine stripping apparatus to be operated at higher speeds. - Preferably, the stripping
orifice 50 comprises a threadedopening 54 in the strippingorifice plate 48, and a complementary threaded strippingdie 56 having a substantially cylindrical body receivable in the threaded opening. In this embodiment, several interchangeable stripping dies, such as the ones shown inFIGs. 5, 6 and 7 and 8 , can be employed. In an additional preferred embodiment (not shown), the stripping orifice comprises an opening in the strippingorifice plate 48 and a channel affixed on the stripping orifice plate for slidably receiving a stripping die having a substantially planar rectangular body. - The size and configuration of the stripping orifice can be matched to the particular species or variety of plant being harvested. It has been found that certain shapes are more effective at catching and removing plant material from a vine as it pulled through the stripping
orifice 50. The circular opening 58 of the threaded stripping die shown inFIG. 5 , and the "star" shaped openings 60 and 62 of the threaded stripping dies shown inFIGs. 6 and 7 have been used with success with hop vines. In particular, the star shape has been found to be especially effective in removing plant material, due to the multiple "notches" created by the points of the star. - The purpose of the counter-rotating wheels,
first wheel 22 andsecond wheel 24, is to grasp and pull the vine and twine through the strippingorifice 50. In order to accomplish this pulling action, thefirst wheel 22 is rotated in a first direction Ri, and thesecond wheel 24 is rotated in a second direction R2, opposite the first direction. The counter-rotation of the wheels is best shown inFIG. 4 , wherein it can be seen that the first wheel is rotated in a counterclockwise direction, and the second wheel is rotated in a clockwise direction. The result of the counter-rotational relationship of the wheels is that at thecontact point 52, both wheels are rotating in a direction away from the strippingorifice 50. - The rotating means 28 and 30 shown in
FIGs. 1 through 4 provide power to effect the rotation of thewheels - In a preferred embodiment shown in
FIGs. 1 and2 , thevine stripping apparatus 10 further includes acowling 64, which provides a safety barrier to protect the operator from the rotatingwheels - In use, the
vine stripping apparatus 10 rapidly and thoroughly removes substantially allplant material 66 from a vine and deposits it in a collection location 68, and ejects the stripped vine 70 in adisposal location 72. SeeFIGs. 4 and9 . The process of stripping a vine using the vine stripping apparatus described herein includes first obtaining anunstripped vine 74 that has been severed from its root. As referred to herein, an "unstripped vine" is a vine that has not been stripped of leaves and other plant material, and may or may not include the support twine on which the vine was grown. In the case of hop vines, both the root end and trellis end of the vine and twine must be severed, leaving a completely detached unstripped vine. Thewheel rotating means first wheel 22 in direction Ri andsecond wheel 24 in direction R2. Theroot end 76 of the unstripped vine is inserted into the strippingorifice 50 until it reaches thewheel contact point 52. As the wheels turn, the root end of the unstripped vine is grasped between the wheels and the vine is pulled through the stripping orifice.Plant material 66 growing on the vine is too bulky to pass through the stripping orifice, and is therefore pulled off of the vine by the stripping orifice and deposited in the collection location 68. As the unstripped vine is continuously advanced, it is stripped clean and the stripped vine 70 is deposited in thedisposal location 72. The stripping process occurs rapidly - under ideal conditions, approximately thirty 18-foot vines can be stripped per minute. - An advantage of the process described herein is that nearly all of the
plant material 66 is removed from the vine, resulting in very little waste. An additional advantage of the process is that the plant material sustains very little damage during this stripping process. This is due to the "self-cushioning" effect that results as the vine passes through the strippingorifice 50. The plant material tends to accumulate against the stripping orifice, forming a cushion against which additional plant material is pressed as the vine is pulled through. - In an embodiment of the invention, at least one
vine stripping apparatus 10 is mounted to amobile harvesting unit 78 suitable for use in the field where the crop to be harvested is grown. The mobile harvesting unit is used in combination with a receptacle 80 for collecting the harvestedplant material 66 and transporting it to a central processing facility for further sorting and processing. The mobile harvesting unit may be adapted to be towed by another powered vehicle, as shown inFIGs. 9 and10 , or it may include an integrated power source for moving through the field. In addition, the mobile harvesting unit or the powered vehicle may include a power source for providing power to the rotatingmeans - The
mobile harvesting unit 78 is adapted to receive one or more vine stripping apparatuses, as shown generally inFIGs. 9 and10 . Aconveyor 82 is provided in the bed of the vehicle for receiving theplant material 66 and carrying it to be deposited in the receptacle 80. Eachvine stripping apparatus 10 is positioned on the vehicle so that thevine stripper 26 is substantially oriented toward the conveyor. Anoperator platform 84 in the vehicle provides a secure location for the operator to stand as he or she feedsunstripped vines 74 into thevine stripping apparatus 10. - Reference is next made to
FIG 11 , which illustrates a general process of separating a cannabis plant stem from cannabis leaves and buds using a system designated generally at 300. Thesystem 300 will be described in more detail with reference toFigures 12-14 . The illustrated process begins with the act of providing acannabis plant 350 including both astem 354 and a plurality of leaves andbuds 352, designated generally at 310. It will be appreciated that thecannabis plant 350 may be any type of cannabis including various varieties, strains, growing techniques, stages of harvest, etc. Likewise, thecannabis plant 350 may be either in a wet or dry state depending on whether a pre-harvesting drying act was performed prior to stem harvesting. A user then selects and orients thestem 354 with an orifice or die on aharvesting system 300, designated generally at 320. The act of selecting the orifice to correspond to thestem 354 includes selecting an orifice with a diameter that substantially corresponds to the diameter of thestem 354. The more closely the diameter of the orifice corresponds to the stem diameter, the more efficient the operation of the stem harvesting process and system. Thesystem 300 separates the stems 354 from the leaves andbuds 352 as represented by theindependent acts buds 352 being directed into a bin directly below the orifices while the stems are routed to a second depository (not shown) behind the orifices. - Reference is next made to
FIG 12A-B which illustrate views of a cannabis stem harvesting system, designated generally at 400. The system includes aframe member 420, diemember 430, first rotatingcylindrical member 460, a second rotatingcylindrical member 480, rotation system, and apinch region 490. The illustratedframe member 420 includes a rigid structural support frames and structures. Theframe member 420 may comprise a metal material including but not limited to aluminum or steel. The illustratedframe member 420 includes four castor wheels to enable translation of thesystem 400. Theframe member 420 further includes various shielding panels to isolate and protect a user from the first and second cylindrical rotatingmembers bottom cowling 422. Theframe member 420 may further include one or more receptacles for receiving plant material. In the illustrated embodiment, twoharvest bins 424 are disposed below thedie member 430 on the user side which is opposite the first and second cylindrical rotatingmembers harvest bins 424 are configured to receive the plant leaves and buds as shown inFigure 11 . Although not shown, it will be appreciated that a second set of stem bins or receptacles may be included to catch the separated stems as shown inFigure 11 . Various other equipment may be incorporated into the process including but not limited to conveyors for transporting buds and leaves. Theframe member 420 is coupled to both thedie member 430 and the first and second cylindrical rotatingmembers members member 460 is positioned above the second cylindrical rotatingmember 480. The orientation or configuration further includes orienting the first and second cylindrical rotating members in a substantially parallel horizontal and depth alignment. The terms substantially vertical, horizontal, and depth are used in accordance with the visual representations shown inFigures 12A-B . - The
die member 430 is a single layer panel including aplate 432 and a plurality oforifices 434 disposed on the plate. Theplate 432 shown in the illustrated embodiment is vertically concave with respect to the user. The purpose of the concave surface is to position the plurality oforifices 434 close (in proximity) to the first and second cylindrical rotatingmembers orifices 434 in close proximity to the first and second cylindrical rotatingmembers concave plate 432. The plurality oforifices 434 include at least two holes having different diameters. The plurality oforifices 434 are oriented on theplate 432 horizontally in a manner such that each of the orifices are substantially equidistant to the first and second cylindrical rotatingmembers orifices 434 may each include shapes that are circular or non-circular to accommodate various stripping properties. Theorifices 434 inherently form an edge at the junction with theplate 432. The thickness and composition of theplate 432 will affect the stripping characteristics of theorifices 434. The edge may be orthogonal, ramped, or curved so as to further affect the stripping characteristics of the system. Extensive testing with respect to cannabis has resulted in maximum and minimum sizing of theorifices 434 between one quarter inch and two inches (0.12954 and 0.0508 meters). - The first and second cylindrical rotating
members circumferential surface second axle circumferential surfaces members circumferential surfaces cylindrical members circumferential surfaces members circumferential surfaces members second axles circumferential surfaces circumferential surface 462 rotating in a counter-clockwise orbit and the second circumferential surface rotating in a clockwise orbit with respect to the perspective shown inFigures 12A-B . This opposite rotation causes a pulling force to be exerted on an object positioned between the first and second circumferential surface. The pulling force is directed away from thedie member 430. - At least one of the first and second cylindrical rotating
members rotating members rotating members Figures 12A-B but will be illustrated in more detail with reference to the figures below. The rotation system may be configured to rotate the first and second cylindrical rotatingmembers members - The
pinch region 490 is a region of closest proximity between the first and secondcircumferential surfaces members rotating members circumferential surfaces axles Figure 12B . Thepinch region 490 extends across thecircumferential surfaces orifices 434 discussed above further achieves a consistent alignment and spacing with thepinch region 490 in the illustrated embodiment. Thepinch region 490 may include a coupling between the first and secondcircumferential surfaces pinch region 490 are critical for the safe and efficient operation of thesystem 400. The distance to thepinch region 492 from theorifices 434 is also a critical measurement in the operation of theoverall system 400. Extensive testing has concluded that the distance to thepinch region 492 must be under six inches (0.1524 meters) to function properly for harvesting of cannabis with an optimal value of approximately two inches (0.0508 meters). This discovery is in contrast to the operation of conventional stripping systems which were adapted for stalk type plants such as a tobacco. For at least this reason, conventional systems cannot be adapted to function for cannabis without significant inefficiencies or diminished user safety. - Reference is next made to
FIG 13 which illustrates a view of an alternative cannabis stem harvesting system, designated generally at 500. Thesystem 500 includes aframe member 520, adie member 530, first rotatingcylindrical member 560, second rotatingcylindrical member 580,pinch region 590, androtation system 540. Thealternative embodiment system 500 shown inFigure 13 illustrates various alternative configurations with respect to thesystem 400 shown inFigures 12A-B while still implementing the same overall novel concepts. The components of the alternative system function in the same manner but incorporate alternative implementations or size parameters. First, theframe member 520 configuration eliminates the cowling and various shielding plates. Theframe member 520 includes a top shielding plate rather than the vertical plates shown in the previous embodiment. Second, thedie member 530 and configuration of the first and second cylindrical rotatingmembers plate 532 of thedie member 530 is tilted away from a user, thereby offering a better field of view to the user. In addition, theplate 532 tilting allows the stems to translate through the system into conveyors or binds without encountering operational components. Likewise, the positioning of the first cylindrical rotatingmember 560 is offset/tilted back from the second cylindrical rotatingmember 580 by a corresponding angle. The first and second cylindrical rotatingmembers die member 530 also includes a plurality oforifices 534 oriented equidistant to the cylindricalrotating members plate 532 and cylindricalrotating members orifices 534 at an angle which may allow a user to efficiently orient, align, and insert cannabis plants into the optimal orifice. Theorifices 534 will also maintain a consistent distance from thepinch region 590 as a result of the offset of the first cylindrical rotating member. Third, the illustratedsystem 500 shows a particular configuration of therotation system 540 with respect to the first and second cylindrical rotatingmembers rotation system 540 includes amotor 542 which is coupled only to the second cylindrical rotatingmember 580. The second cylindrical rotatingmember 580 thereby functions as a driver, while the first cylindrical rotatingmember 560 functions as a follower. In addition, the second cylindrical rotating member 582 includes a gear type circumferential surface and composition. The gear type composition may include a metal or nylon gear having a plurality of radial ribs/teeth across the circumferential surface as shown. The first circumferential surface may be coupled to the second circumferential surface at thepinch region 590 to enable the counter-clockwise rotation of the secondcylindrical rotation member 580 to automatically drive the clockwise rotation of the first cylindrical rotating member. Fourth, thesystem 500 illustrates astem bin 526 disposed below the cylindricalrotating members Figure 11 . - Reference is next made to
FIG 14A-B which illustrate views of another alternative cannabis stem harvesting system, designated generally at 600. Thesystem 600 includes aframe member 620, adie member 630, first cylindrical rotatingmember 660, second cylindrical rotatingmember 680, androtation system 640. Thealternative embodiment system 600 shown inFigures 14A-B illustrate various alternative configurations with respect to thesystem 400 shown inFigures 12A-B while still implementing the same overall novel concepts. The components of the alternative system function in the same manner but incorporate alternative implementations or size parameters. Thesystem 600 also includes an angulation of thedie member 630 and cylindricalrotating members system 500. Theframe member 620 further incudes a top andfront cowling 622 around thedie member 630 and cylindricalrotating members plate 632 of thedie member 630 includes a concave surface similar to thesystem 400 shown inFigures 12A-B . The concave surface of theplate 632 optimally positions the plurality oforifices 634 closer to thepinch region 690, thereby reducing the distance to the pinch region (not shown). The concavity of theplate 632 thereby maintains theoptimal orifice 634 distance to thepinch region 690 of a smaller diameter cylindrical rotating member while allowing for a larger diameter cylindrical rotating member. Larger diameter cylindrical rotating members are preferred for optimizing gripping force at thepinch region 690. Theframe member 620 incudes a simplified set of support structures coupled to support the components of thesystem 600 in the manner shown. Therotation system 640 is coupled to theframe member 620 so as to position amotor 642 adjacent to cylindricalrotating members respective axles motor 642 is coupled indirectly to thesecond axle 684 via gearing members to facilitate corresponding motor driven rotation of thesecond axle 684. The first and secondcircumferential surfaces pinch region 690 to facilitate the driver-follower operation of the cylindricalrotating members system 500. An adjustable pressure system (not shown) between the first and second cylindrical rotatingmembers frame member 620. The adjustment slot may include a plurality of indexing marks representing certain pressure levels. Various support structures are shown in the exploded view ofFigure 14B to illustrate the optimal orientation of the components. - Reference is next made to
FIG 15 , which illustrates a perspective view of an alternative embodiment of cylindrical rotation members designated generally at 760, 780. The alternativecylindrical rotation members Figures 16A-B illustrate various alternative configurations with respect to thesystem 400 shown inFigures 14A-B while still implementing the same overall novel concepts. The components of the alternative system function in the same manner but incorporate alternative implementations or size parameters. The first and secondcircumferential surfaces rotating members system 500. The first and second cylindrical rotatingmembers circumferential region 762 comprises a rubber material with a durometer of 45 Shore A and a diamond pattern composed of 1/8 inch (0.0254 meters) grooves. The embodiment shown inFigure 15 is unique in that the second circumferential surface includes afirst region 782 and asecond region 783. Thefirst region 782 of the second circumferential surface comprises a rubber material with a durometer of 45 Shore A and a horizontal pattern composed of 1/8 inch ((0.0254 meters) grooves. Thesecond region 783 of the second circumferential surface comprises a harder non-rubber (i.e. steel, plastic, nylon, etc.) material having large flanges acting as a gear. Thesecond region 783 of the second circumferential surface is specifically oriented with the plate (not shown) to align with at least one of thelargest diameter orifices 734. Extensive testing has concluded that the particular circumferential surface configuration optimizes the feeding of cannabis stems. In particular, the rubber to rubber configuration is optimal for smaller diameter stems because the specific forces at the pinch region are balanced between pulling and repelling excess material. Likewise, the rubber to gear configuration is optimal for larger diameter stems because the forces at the pinch region are balanced. Various support structures are shown in the exploded view ofFigure 14B to illustrate the optimal orientation of the components. - Reference is next made to
FIG 16A and B , which illustrate alternative embodiments of aplate 732 with the plurality oforifices 734. Extensive testing has concluded that the optimal three dimensional shape for the orifices includes a star-like shape with rounded (non-sharp) internal edge. - It should be noted that various alternative system designs may be practiced in accordance with the present invention whose scope is defined by the claims.
