Abstract: 380,129. Packeting cigarettes in boxes. JAGENBERG, G. MEYER-, 107, Himmelgeisterstrasse, D³sseldorf, Germany. June 11, 1931, No. 17000. [Class 94 (i).] The machine, which is diagrammatically shown in plan in Fig. 1, packs cigarettes in boxes of the hinged lid type. The boxes are fed from a hopper 7 to position I, where they are opened, at position II a transverse lining strip is inserted, and at position III a longitudinal strip is superposed, each being pressed down and folded within the box to conform to the interior. At subsequent stations operations take place as follows : IV, insertion of the bottom layer of cigarettes into the box ; V, insertion of a division sheet ; VI, transfer of the top layer of cigarettes on to a conveyer ; VII, transfer of this layer to an adjusting and tnrniug device; VIII, adjustment of incorrectly placed cigarettes ; IX, disposal of the layer in overlapping formation ; X, insertion of the layer into the box ; XI, closing the box. Opening boxes. The closed boxes are fed by a plunger from the base of a hopper 7, and arrive between guiding rails 35, Fig. 3, along which they are moved by conveying means 5. The lid is gripped on both sides by grippers 10 on bell-crank levers 11 lowered into position by an arm mounted to rotate about a shaft 16, the axis of which is a continuation of the axis of the hinge of the box. The opening and closing of the grippers is effected by a stop member 12 on an arm 13 actuated by fixed abutments to allow a spring to draw them together, and to force them open at the appropriate moments. Inserting lining strips. At stations II a transverse lining strip 22, Figs. 8 and 10, is inserted and pressed into position, and at station III, a longitudinal strip 44 is added. The latter operation is shown in Fig. 10. Grippers 38 draw forward a strip from a roll 58, Fig. 1, into position over the box, and an arm 25, carrying pressing plates opened by wedge action, descends and forces the strip into the corners of the box. At the same time, plates 32 press the strip down over the edges of the box, and a knife 40 severs the strip from the web. In an alternative construction, the strips may be delivered from a stack by a suction device. Inserting cigarettes. The cigarettes to form the bottom layer are contained in a hopper 45, Figs. 11 and 12, the bottom layer resting on a plate 47 formed with grooves 46. A plunger 48 forces the layer beneath a brush 49, which is moved transversely to cause the cigarettes to assume an overlapping formation ; and into the box, which has been tilted as shown in Fig. 11 to facilitate the entry. For this purpose, a portion of the rails 35 are mounted on a yoke 50 pivoted at 51. More than one layer may be inserted at this point, and the cigarettes are pressed into position by an elastic plunger 52. A division sheet is added at position V by a suction device, and the box moves to position X for receiving the top layer of cigarettes, which must be so arranged that all the inscriptions lie upwards. The cigarettes are fed, at positions VI, by a plunger 61, Fig. 1, from a magazine 60 on to a conveyer chain comprising grooved plates 62. The device W for turning the incorrectly placed cigarettes axially about 180‹ is described in Specification 380,141. A plunger 68 feeds the cigarettes into the device, and, after adjustment, further movement of the plunger feeds the cigarettes on to a plate 75, Fig. 21, pivotally mounted at 76. The plate tilts into an oblique position and an arm 77 arranges itself in parallelism therewith. A slide 80 is drawn to the right to collect the cigarettes into an overlapping group, and a pusher 78 descends and pushes the group over a plate into the box, which is inclined in the same way as for the first insertion. A plunger presses the charge into position and the box moves to position XI for closing.
