Abstract:
A cigarette packer (1) incorporates a station at which cigarettes (2) are formed into groups (12) and from which the groups (12) are advanced by a first conveyor (13) along a first feed path (P) toward a wrapping station (16). A first inspection device (24) located along the first feed path (P) detects initially whether or not there are any defective cigarettes (2) in each group (12), and a second inspection device (45) located along a second conveyor (30) then identifies the single defective cigarettes (2) detected by the first device (24); the second inspection device (45) operates in conjunction with a rejection unit (46) by which defective cigarettes (2) are removed from the second conveyor (30).
Abstract:
Cigarettes are formed into groups by a device comprising a hopper through which to direct a flow of cigarettes, a conveyor with pockets moving intermittently past a discharge outlet of the hopper, and a reciprocating pusher located on the side of the hopper opposite from the conveyor by which a portion of the flow corresponding to one group is directed with each forward stroke into a respective pocket. To avoid damage of the kind often associated with sliding contact and axial compression, the cigarettes adjacent to those ejected by the pusher are restrained when their cylindrical surfaces are attracted by suction generated through ports located inside the hopper.
Abstract:
Blocks of plain or filter cigarettes are accumulated in at least two group building assemblies each of which comprises at least two block forming units receiving cigarettes by gravity flow by way of upright ducts. The assemblies are adjacent the path of a series of successive receptacles which serve to transport discrete blocks stepwise to a multiple-track packing machine. The units accumulate blocks of cigarettes during intervals which include the duration of at least one stepwise movement of the receptacles and that of at least one period of standstill of the receptacles. Such intervals suffice to ensure satisfactory gathering of cigarettes into blocks of required size and shape at a frequency which is required for full-speed operation of the multiple-track packing machine.

Abstract:
Apparatus for transporting cartons of cigarette packets or analogous block-shaped commodities employs an indexible turret which advances a series of successive equidistant commodities along an arcuate horizontal path into the inlet of a straight horizontal second path defined by an elongated reach of an endless belt conveyor. The conveyor carries spaced-apart receptacles each defined in part by an outwardly extending retaining element affixed to the belt conveyor, and in part by a two-armed lever which is pivotably mounted on the conveyor and is biased by one or more springs to an idle position in which the respective receptacle can receive a commodity from the turret during travel past the inlet of the second path. A commodity which is in the process of entering a receptacle at the inlet bears upon one arm of the lever against the spring bias to thus move the other arm to a position in which the other arm cooperates with the retaining element to advance the commodity along the second path. The other arm and the retaining element cooperate with one or more fixed rails to confine the commodity in a filled receptacle to movement along the second path.
Abstract:
A method and unit for feeding collars for packets of cigarettes to a continuous packing line, whereby the collars, picked up successively and in steps by a transfer device, are transferred rapidly by the transfer device to a continuously-moving supply assembly, which feeds the collars successively to the packing line after squarely folding two lateral wings of each collar; the collars being fed on to the packing line with the lateral wings crosswise to a traveling direction of the line.
Abstract:
The unit for forming groups of cigarettes has at least one substantially U-shaped pocket designed to receive in succession at least two layers of cigarettes, in which the cigarettes are parallel with a longitudinal axis of the pocket, the two layers being arranged one above the other to define a respective group; the unit having at least one holding element and, if the group has at least one gap, the unit having at least one dummy positioned parallel with the axis, both being mobile, under the thrust of an actuator, between a home position and an operating position, in which the element and the dummy are positioned respectively outside and inside the pocket, to respectively lock the group of cigarettes within the pocket, and to compensate the gap.
Abstract:
A system for inspecting the ends of cigarettes prior to their packaging on a conveyor line. The system provides telecamera units which produce images of the ends of a group of cigarettes. A processing unit then analyses the brightness level of a given area on each cigarette end. The processing unit then counts the total number of areas having a brightness level within a given range and compares that number with that of a reference end image for determining the existence of defects. An expulsion unit is further provided for rejecting those groups of cigarettes which fall below the requirements of the reference end image.
Abstract:
Successive rows of cigarettes delivered axially from a packing machine hopper outlet (12) are engaged by a cyclically-movable transfer member (24, 32, 425) which accelerates each row sideways and closes up spaces between cigarettes (C) before transferring the row to a conveyor (22) moving continuously at machine speed. The conveyor may be a drum (22) which transfers the cigarettes to a pocket conveyor (62) in which the cigarette bundles are formed, or it may be the pocket conveyor itself. The hopper may have several spaced outlets (12) so that rows may be supplied to the pocket conveyor (62) at spaced locations along its length to provide multi-layer bundles.
Abstract:
A buffer storage apparatus includes a mechanism for removing a product travelling from one location to another, and an elongate reservoir belt movable in thedirection of its elongation from a stowed position wound on a spool, past the removing mechanism to receive the product and thereafter to a product storage position where the charged reservoir belt is wound on a furtherspool. When the reservoir belt is being wound round one spool the reservoir is being unwound from the other. The reservoir belt itself is preferably provided with pockets or dividers which, apart from separating the articles, serve as spacers between layers of wound belt and thus eliminate the possibility of articles being compressed between layers of conveyor belt wound round the loaded conveyor spool/drum. The system is designed to handle a variety of sizes and shapes of articles such as rectangular products like chocolate bars or cigarette packages, bottles, cylindrical or rod-shaped articles such as cigarettes, tin cans, etc.
