This disclosure generally relates to apparatuses for filling and packing receptacles and related methods. In particular, but not exclusively, the disclosure relates to apparatuses for filling and packing tubular herb receptacles with herb material and related methods.
Paper, cellulose or hemp tubular receptacles are often filled by processed plant material, such as an herb mixture, to allow it to be set alight so that it can be smoked. Traditionally, tubular receptacles (e.g., paper cones) have been filled manually by inserting an amount of herb mixture into the tubular receptacle and thereafter packing the mixture by striking the tubular receptacle on a hard surface until a desired density is obtained. This manual process of filling and packing tubular receptacles is laborious and time consuming.
Different apparatuses have been suggested to address the shortcomings of the manual filling process. For example, US Patent Publication No. 2016/0120212 discloses a filling apparatus for simultaneously filling and packing a plurality of tubular receptacles with herb material. Such apparatuses, however, may be overly complex or suffer from various other deficiencies and drawbacks.
Embodiments described herein provide apparatuses and related methods for filling and packing herb receptacles with herb material in a particularly efficient manner.
According to one example embodiment, an apparatus for filling and packing herb receptacles with herb material may be summarized as including: a base assembly having a vibrating platform that is movable between a loading configuration and a packing configuration; a holding tray positionable over the base assembly and having a plurality of holding tray apertures each sized to receive a respective herb receptacle and to encircle the herb receptacle at an intermediate location along a longitudinal length of the herb receptacle; and a loading tray removably coupled to the holding tray and having a plurality of loading tray apertures each sized to receive a respective herb receptacle and to encircle the herb receptacle at an upper location along a longitudinal length of the herb receptacle.
The apparatus may further comprise a metering device removably coupled to the loading tray and having a plurality of metering cavities for receiving a respective dose of the herb material. The metering device may be movable relative to the loading tray to enable the respective dose of the herb material to be selectively deposited in a respective herb receptacle when moving the metering device from a fill configuration, in which the metering cavities are isolated from internal cavities of the receptacles, to a deposit configuration, in which the metering cavities are open to the internal cavities of the herb receptacles. The metering device may include a gate structure that is slidable relative to the loading tray to enable the respective dose of the herb material to be selectively deposited into the respective herb receptacle when moving from the fill configuration to the deposit configuration. The metering device may be removably supported on the loading tray to enable removal of the metering device from the loading tray prior to packing the herb receptacles with the herb material. The apparatus may further include one or more supplemental metering plates positionable on the metering device to adjust a dose volume of the herb material to be deposited in the herb receptacles. Each supplemental metering plate may include a plurality of metering apertures alignable with the metering cavities of the metering device to effectively increase a dose volume of the metering cavities.
The base assembly of the apparatus may include a base structure and the vibrating platform may be movably coupled to the base structure to enable movement of the vibrating platform between the loading configuration and the packing configuration. For example, the vibrating platform may be movably coupled to the base structure via a user manipulable lift arrangement. The user manipulable lift arrangement may include a plurality of cams and at least one linkage member.
When the vibrating platform of the base assembly is in the loading configuration, the loading tray and holding tray may support the herb receptacles with terminal ends of the herb receptacles in contact with the vibrating platform and with loading ends of the herb receptacles at or below an upper surface of the loading tray. Conversely, when the vibrating platform of the base assembly is in the packing configuration, the loading tray and holding tray may support the herb receptacles with terminal ends of the herb receptacles in contact with the vibrating platform and with loading ends of the herb receptacles above the upper surface of the loading tray.
The vibrating platform may be configured to move the herb receptacles relative to the holding tray and the loading tray when moving from the loading configuration to the packing configuration.
The base assembly of the apparatus may further include an electric vibrator fixed to the vibrating platform to enable selective vibration of the vibrating platform during packing of the herb receptacles. A frequency and/or an intensity of the electric vibrator may be variable to adjust a packing quality of the herb receptacles.
In some instances, the loading tray may be removably supported above and spaced apart from the holding tray. The loading tray apertures may be aligned coaxially with the holding tray apertures via a plurality of alignment guides. The loading tray may be spaced apart from the holding tray such that a mid-section of the herb receptacles are visible when filling and packing the herb receptacles with the herb material. Each loading tray aperture may be sized to closely encircle the herb receptacle at the upper location along the longitudinal length of the herb receptacle to minimize an amount of herb material bypassing the herb receptacle during filling.
The holding tray may be configured to independently support the herb receptacles when removed from the base assembly. For example, in some instances, each holding tray aperture may be sized to engage a portion of the herb receptacle at a location above the intermediate location when lifting the holding tray with the herb receptacles received therein such that the holding tray may be used to carry the herb receptacles.
According to another example embodiment, a method of filling and packing herb receptacles with herb material may be summarized as including: supporting the herb receptacles in space on a vibrating platform with the aid of a support structure having a plurality of holding apertures each sized to receive a respective one of the herb receptacles and to encircle the herb receptacle at an intermediate location along a longitudinal length of the herb receptacle; dosing herb material into the herb receptacles; repositioning the vibrating platform from a loading configuration to a packing configuration to lift the herb receptacles with the herb material relative to the support structure; and packing the herb receptacles with the herb material with the vibrating platform in the packing configuration.
The method may further include, during the dosing of the herb material into the herb receptacles, supporting the herb receptacles in space on the vibrating platform with the further aid of a loading tray.
Dosing the herb material into the herb receptacles may include filling a plurality of metering cavities of a metering device with the herb material and translating the metering device relative to the loading tray to expose the metering cavities to internal cavities of the herb receptacles.
The method may further include removing the metering device from the loading tray prior to repositioning the vibrating platform from the loading configuration to the packing configuration.
The method may further include, after packing the herb receptacles with the herb material, removing the loading tray from support of the herb receptacles and relocating the support structure with the herb receptacles with the packed herb material supported therein for further processing.
The method may further include adjusting a packing quality of the herb material in the herb receptacles by modifying a frequency and/or an intensity of vibratory motion of the vibrating platform during the packing of the herb receptacles.
In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. However, one of ordinary skill in the relevant art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known devices, systems and processes associated with filling and packing herb receptacles with herb material may not be shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments.
Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is as “including, but not limited to.”
