A stem removal device for a cigarette making process is disclosed, including a feeding unit (N1), a flexible air sorting unit (N2), a pure tobacco collection unit (N3), a tobacco conveying unit (N4), a coarse stem removal unit (N5) and a fine stem removal unit (N6). A method for removing the stems during the cigarette making process using the stem removal device is also disclosed.

A system includes a cradle, a tray assembly, a plurality of supports, and a vibrator. The tray assembly removably couples to the cradle. The tray assembly has a plurality of holes and a handle. The handle facilitates separating the tray assembly from the cradle. The plurality of supports extend from the tray assembly at positions on the tray assembly that correspond to positions of the holes in the tray assembly. The supports are sized and dimensioned to hold paper tubes. The vibrator vibrates the tray assembly coupled to the cradle to distribute loose material placed on the tray assembly through the holes in the tray assembly and fill the paper tubes in the supports with the loose material.

A tube loading, filling and sealing system that includes a tube loading apparatus, a tube filling apparatus, a tube sealing apparatus configured to receive and seal a plurality of tubes, and a weighing apparatus configured to weigh a plurality of filled tubes. A method of filling tubes with a herb mixture using a tube loading, filling, and sealing system. The method including loading the tubes into a tube filling apparatus using a tube loading apparatus, filling the tubes loaded into the tube filling apparatus with a herb mixture, sealing the filled tubes using a tube sealing apparatus, and weighing the sealed tubes using a weighing apparatus.

This invention concerns a tube filling apparatus (10). The apparatus includes a base (40) and a filling assembly (20) mountable on the base (40). The filling assembly (20) has a number of tube receiving recesses wherein tubes may, in use, be received. The apparatus (10) further includes a vibration plate (32) which is locatable between the base (40) and the filling assembly (20). In use, the tubes rest on the vibration plate (32) when they are located in the recesses. The apparatus (10) may also include transducer such as a speaker which is connected to the vibration plate (32) for, in use, vibrating the vibration plate (32), which is capable of moving independently from the filling assembly (20). This invention also concerns a method of filling tubes.

The present invention relates to an automatic cigarette making system which is enabled to provide the various function of production of the cannabis cigarette by a single system which is further enabled to reduce the cost and the time of the production of the cannabis cigarette.
