A belt conveyor device for groups of delicate rod-shaped objects, especially in cigarette packaging machines, which device includes a continuous conveyor belt (3) travelling around pulleys (4, 5), at least one of which is driven, and attached to whose outer face are a plurality of conveyor housings (6) each for one group of delicate rod-shaped objects (S, S', S'), housing (6) are equidistant form each other and carried stepwise in succession from a loading station to an unloading station, these stations being situated near two opposite ends of the conveyor belt (3). The conveyor housings (6) consist of two separate and mutually complementary parts (106, 206) divided at at least one plane transverse to the plane defined by the conveyor belt (3) and transverse to the direction of advance of the conveyor belt (3), each housing part (106) being attached firmly to the conveyor belt (3) independently of the other associated housing part (206).

Supply hopper for delicate, rod-shaped products, in particular in cigarette packaging machines, which hopper (1) is provided in its lower part with a plurality of separate discharge channels (2), each of which is divided by means of intermediate walls (4) into several ducts (3) which are vertical and parallel to one another, in each of which ducts (3) there is formed at least one substantially vertical row of cigarettes (S) which are superimposed on one another, whereas above the upper end (104) of each intermediate wall (4) there is provided a roller (6) which is horizontal and parallel to the axis of the cigarettes (S) in the hopper (1), and is rotated, preferably with oscillatory motion. According to the invention, in order to prevent to a large extent the formation of bridges of cigarettes which block the ducts (3), the rollers (6) are disposed quincuncially relative to a horizontal plane, i.e. they are alternately offset parallel to one another upwards and downwards.

Device for feeding sheets of, for example, foil, especially for use in cigarette packing machines, with a drum (7) having cells (2') in which the sheets (8) are folded around individual groups (3) of cigarettes (S) as each group (3) of cigarettes (S) is transferred from a transfer drum (1) having cells (2) to the folding drum (7) at a transfer point (T) where the cigarette-carrying cells (2, 2') of the two drums (1, 7) coincide face to face and to where the sheet (8) is fed in a predetermined position with respect to the group (3) of cigarettes (S) and between the cells (2, 2') of the two drums (1, 7) by a pick-up/positioning device (14, 114) associated with the transfer drum (1). The sheet (8) pick-up/positioning device consists of a separate pick-up/positioning drum (14, 114) supported coaxially with the transfer drum (1) and rotated (21) independently of it.

Device for feeding wrapper sheets, especially for use in cigarette

A device with a packaging wheel, for supplying sheets, in particular in cigarette packaging machines, comprises means (20, 20') for collecting/positioning the packaging sheets (F) in a predetermined position, in a transfer station (T), between a cell (101) of a transfer drum (1) which accomodates a group of cigarettes (S) and an empty cigarette-carrying cell (102) of a folding drum (2) opposite. During transfer into the cell (102) of the folding drum (2), the group of cigarettes (S) draws the sheet (F) which is folded automatically in a U-shape around the cigarettes (S) by the cigarette-carrying cell (102). According to the invention, the collecting/positioning means (20, 20') consist of mechanical gripper means for grasping the packaging sheet (F) which are provided at least on the front side of each cigarette-carrying cell (101) of the transfer drum (1), with reference to the direction of rotation of the drum.
