Abstract: 302,613. Molins, W. E. Aug. 18, 1927. Packeting cigarettes in boxes.-In a packing machine for cigarettes, a predetermined number of cigarettes are periodically removed from a hopper and deposited in a box having a hinged lid, and the box is closed, all the operations being automatic. The cigarettes are fed from a hopper, which may be of the type described in Specifications 316,326, 238,355, 263,521, and 267,231, by a conveyer adapted to move the required number of superimposed rows along the bed 2, Fig. 3, of the machine. The cigarettes mav be moved through mechanism such as is described in Specification 165,891 for enveloping the batch in a strip of foil, so that the foil lies partly along the upper surface of the batch, and covers the front and bottom thereof, extending beyond the end of the cigarettes in engagement with the pusher of the conveyer. The pusher is tripped, and a member 7, Figs. 5 and 7, engages the batch to forward it into a box 8. The member 7 is mounted on an arm 24 adapted to oscillate with an arm 26, Fig. 7, on a slide 22 reciprocated by a quadrant 10, Fig. 5, pinion 18 and rack. During the forward movement of the slide 22, a roller 27 on the arm 26 moves between fixed guides 28, 29 and lifts a pivoted guide 30. On the return movement, the roller traverses the upper surface of the guides 30, 29 and falls between the guides 28, 29. The member 7 thus moves on a level with the bed 2 during the feeding stroke and is raised on the return stroke to clear the succeeding batch. During the feeding stroke, the cigarettes pass over a plate 32 and between guides 33, Fig. 3, and fall into the box 8 in the disposition shown in Fig. 8, a pivoted plate 34 assisting the insertion. The boxes are fed from a magazine 41, Fig. 2, by a pusher 37 on a conveyer 36, past rollers 43 adapted to grip the lower portion of the box while obliquely mounted rubber rollers 44 engage the lid of the box and effect an initial opening. The opening is completed by a curved guide 46 so that the box arrives at position D completely opened. On arrival at this position, a roller 47 on the pusher 37 falls down a step 48 and releases the box, which is stationary during the filling. A trip plate 49 ensures the descent of the pusher. The pusher is raised by the engagement of the roller 47 with stops 50 so as to remove a previously filed box. Succeeding boxes push the filled boxes away from the filling position. The box is next taken beneath a labelling mechanism such as is described in Specification 305,684, [Class 73, Labels &c.], and a gummed strip 51, Fig. 8, is applied to the top of the box. During the further travel of the box, the lid is closed by a guide 58, Fig. 2, the projecting ends of the label and the upstanding portion of the foil being thereby turned down. The box is then discharged from the machine in an open condition. According to the Provisional Specification, the pusher member which feeds the into the box may move at a speed greater than that of the original conveyer, and the upstanding portion of foil after insertion may be folded down by rotating brushes.
