Apparatus for transferring block-shaped arrays of plain or filter cigarettes in a packing machine has a rotary first conveyor which orbits a set of equidistant pockets for discrete arrays about a first vertical axis. The first conveyor is provided with drives which can pivot the pockets about discrete second vertical axes as well as impart to the pockets translatory movements radially of the first conveyor as well as radially of two turret-shaped second conveyors. One second conveyor delivers arrays to the pockets of the first conveyor, and the other second conveyor receives arrays from the pockets of the first conveyor. The ability of pockets on the first conveyor to perform superimposed pivotal as well as dual translatory movements enables such pockets to advance in close proximity to an in exact alignment with the pockets of the one second conveyor along a relatively long first portion of their endless path about the first axis as well as to advance in close proximity to and in exact alignment with the pockets of the other second conveyor along a relatively long second portion of their endless path about the first axis.

The making of cigarette packs is started by transferring arrays of cigarettes into successive pockets of a transporting unit while the pockets are at a standstill, and by inserting blanks into discrete pouches which are adjacent the front sides of the pockets. The pouches and the pockets are then accelerated, and the blanks are partially folded to overlie the arrays of cigarettes in the adjacent pockets prior to joint transfer of arrays and blanks into the receptacles of a continuously driven endless chain conveyor. The arms are then decelerated whereby the chain conveyor extracts the trailing portions of the blanks from their pouches and the blanks are converted stepwise into inner envelopes. The making of second envelopes around the inner envelopes can begin prior to or after completion of inner envelopes.

Apparatus for making cigarette packs and the like

The lower ends of several ducts which dispense layers of parallel cigarettes are located at different levels adjacent the path of movement of a stepwise advancing chain with receptacles for multi-layer arrays of cigarettes which are to be draped into blanks for conversion into cigarette packs. A discrete endless conveyor is installed between the lower end of each duct and the receptacle which registers with such duct, and each conveyor has one or more pushers serving to transfer layers of cigarettes into the registering receptacles. Each conveyor is driven by a discrete motor, and the conveyors can be started and arrested in a predetermined sequence to ensure that each receptacle which registers with a duct is empty when the apparatus is idle, and that each receptacle which advances beyond the last duct contains a full array of cigarettes.

Apparatus for transferring layers of rod-shaped articles in packing

An apparatus for transferring arrays of cigarettes from the pockets of at least one intermittently driven first conveyor into the pockets of a continuously driven second conveyor wherein the transfer takes place by means of at least one pair of arms which have pockets for arrays of cigarettes and are indexible about a common axis to define for their pockets a path a first portion of which overlaps a portion of the path for the pockets of the first conveyor and a second portion of which registers with a portion of the path which is defined for its pockets by the second conveyor. The pockets of the arms receive arrays from the pockets of the first conveyor while the arms are at a standstill, and the pockets of the arms are in positions for transfer of their contents into the pockets of the second conveyor while the arms move at the speed of the second conveyor. The path portion wherein the pockets of the second conveyor receive arrays from the pockets of the arms is arcuate and its center of curvature is located on the common axis of the arms. The pockets of the arms extend radially of the common axis.

Apparatus for draping blanks around blocks of parallel cigarettes has a continuously driven turret with radially inwardly extending pockets in its peripheral surface. Successive pockets of the turret receive blocks of cigarettes from successive pockets of a first endless belt or chain conveyor which partially overlies the peripheral surface of the turret and carries pushers which transfer the blocks into the pockets of the turret in the region of overlap. First blanks are caused to overlie the pockets of the turret ahead of the region of overlap so that the blocks deform the blanks during transfer into the pockets of the turret. The blanks are provided with flaps and tucks during travel with the turret, and the latter is further overlapped by a portion of a second endless belt or chain conveyor whose pockets receive blocks and the at least partially draped first blanks from the pockets of the turret in the region where the second conveyor overlaps the peripheral surface of the turret. Second blanks are placed across the pockets of the turret ahead of the region of overlap with the second conveyor, and such second blanks are automatically draped around the blocks and the respective first blanks during transfer of blocks and first blanks from the pockets of the turret into the pockets of the second conveyor. The pockets of the conveyors and of the turret receive blocks in such orientation that the respective cigarettes are moved sideways.

Method of an apparatus for packing rod-shaped articles of the tobacco

A hinged lid container for arrays of cigarettes is made of a one-piece blank and has a hollow body with an open end remote from its bottom wall, a collar which is integral with the front wall of the body at the open end and extends in part into the body, and a lid which is integral with the rear wall of the body. The collar has two lateral panels with rhomboidal portions extending beyond the respective sidewalls of the body. The free edges of the lateral panels are inclined with reference to the top wall of the lid when the latter is held in closed position so that its lateral walls abut the sidewalls of the body and are outwardly adjacent the rhomboidal portions of the lateral panels.

Apparatus for testing cigarette packs for the presence or absence of several defects including the configuration of the packs, the orientation of their constituents and the quality of bonds between overlapping constituents has an intermittently driven turret with an annulus of receptacles which are supplied with packs by an intermittently driven feeding conveyor. The receptacles have relatively small engaging devices in the form of spring-biased strips, suction cups and/or simple abutments to locate and hold the packs therein in such a way that by far the major part of each pack remains accessible and exposed for testing by a series of photocells which are disposed at several stations adjacent to the path of movement of the receptacles. Tested defective and satisfactory packs are expelled from their receptacles in two separate portions of the path downstream of the testing stations.

Apparatus for assembling multi-layer blocks of parallel cigarettes has a magazine with several outlets having narrow elongated horizontal openings for the discharge of successive layers of cigarettes. An endless conveyor transports a succession of variable-volume receptacles stepwise along a path a horizontal portion of which extends along the outlets so that the opening of each outlet registers with a receptacle when the conveyor is arrested. The volumes of the receptacles are varied by a system of cams, which act upon movable top walls of the receptacles, in such a way that the volumes of the receptacles exceed the space requirements of the layer or layers therein only while the conveyor is idle, i.e., while the receptacles in register with the openings of the outlets are about to receive and are in the process of receiving layers of cigarettes; during each stage of movement of the conveyor, each receptacle which contains one or more layers of cigarettes is filled to capacity because the system of cams ensures that the movable top wall of each such receptacle is held as close to the nearest layer of cigarettes as is necessary to prevent any misalignment of cigarettes in the receptacles due to rapid acceleration or deceleration and/or abrupt starting or stoppage of the conveyor.

Apparatus for accumulating arrays of superimposed layers of parallel cigarettes has a magazine with three layer-accumulating sections having outlets at different levels and a set of pushers which expel layers of cigarettes from the sections during the intervals of dwell of an intermittently driven conveyor for a set of receptacles each of which accumulates an array by accepting one layer from each of the sections. The top and side walls of the receptacles have aligned slots for stationary and movable portions of retaining devices which prevent the cigarettes forming layers of incomplete arrays from moving relative to each other during abrupt acceleration and deceleration of the conveyor to move the receptacles from section to section. The undersides of movable portions of the retaining devices can be raised above or lowered into alignment with the undersides of the adjacent stationary portions through distances approximating the thickness of a layer. The movable portions are disposed in pairs at the second and third sections, and the stationary portions extend along the first section as well as between successive sections. The first movable portions of the two pairs are connected to each other for simultaneous up-and-down movement, the same as the second movable portions of the two pairs. All of the movable portions are lifted simultaneously when the conveyor comes to a halt, and the first portion of each pair is lowered ahead of the respective second portion while the conveyor is in motion.

Apparatus for subdividing a web of wrapping material into sections of predetermined length has a reciprocable carriage for a pair of grippers which are pivotable into engagement with the web to thereby clamp the web against the carriage while the latter moves forwardly. This advances the web through a distance which approximates but is less than the distance necessary to advance the web by the length of a section. The grippers are thereupon disengaged from the web while the carriage continues to move forwardly, and the web is braked by one or more brushes so that two pawls whose pallets are biased against the web can catch up with a pair of marginal notches in the web. The pallets enter the respective marginal notches and complete the forward movement of the web. A mobile knife cooperates with a stationary knife to sever the web and to thus separate a section from the leader of the web while the carriage moves rearwardly. The web is prevented from sharing the rearward movement of the carriage by the bristles of one or more stationary blocking brushes. An electromagnetically actuatable holder is provided to prevent any movements of the web when the making of sections is interrupted on purpose.

Apparatus for applying labels to successive cigarette packs has a feeding unit which delivers a series of labels downwardly past an adhesive-applying device which coats one side of each label with a hotmelt and through a stationary mouthpiece which directs the oncoming label into one of two pockets on a turntable which is indexible through 180 degrees. The pockets are shorter than the labels so that the outer end portion of the label extends beyond the respective pocket and is placed against one side of a reciprocable back support after the turntable is indexed. A pusher then delivers a cigarette pack against the adhesive-coated side of the outer end portion of the label which abuts against the back support so that the outer end portion is caused to adhere to one side face of the pack. The label is thereupon folded over additional sides of the pack while the latter moves past and beyond the turntable and pushes the back support in the same direction. The latter is thereupon retracted, moved counter to the direction of forward movement of the pusher and reinserted into the path of packs so that it is ready to support the uncoated side of the outer end portion of the next label which arrives when the turntable is indexed again through an angle of 180 degrees.

Apparatus for attaching adhesive-coated sheets to cigarette packs or the

Apparatus for alternately withdrawing lowermost sheets from stacks of sheets in two magazines has a frame which is reciprocable below the magazines along a horizontal path between two end positions and carries a main support, two auxiliary supports which flank the main support, and a suction wheel between the main support and each auxiliary support. The suction wheels are driven in phase with the movement of the frame whereby the wheels turn clockwise while the frame moves in one direction and anticlockwise while the frame moves in the opposite direction. Two toothed belts have end portions which are anchored in a tensioning device between the magazines, and the belts are trained over pulleys of the suction wheels and pulleys of rollers constituting the main support. One suction wheel attracts one edge portion of the lowermost sheet in one of the magazines, the main support is located below such lowermost sheet, and one auxiliary support is located below the lowermost sheet in the other magazine when the frame assumes one of its end positions. When the frame thereupon moves toward the other end position, the one wheel peels the lowermost sheet off the adjacent sheet while the main support moves below the lowermost sheet in the other magazine and the other auxiliary support moves below the fresh lowermost sheet in the one magazine.

Apparatus for removing sheets from stacks

Apparatus for making and manipulating sheet-like paper, plastic or metallic blanks in a packing machine has a pivotable conveyor with a gripper which pulls the leader of a running web across the path of successive mandrels or cigarette packs on an indexible turret whereby the gripper overcomes the resistance of a mechanical or pneumatic clamping device which holds the leader of the running web in a position in which the leader can be engaged by the gripper when the conveyor completes a return stroke. The running web is severed by a pair of knives which are installed between the clamping device and the gripper and are caused to cut the web when the gripper reaches an end position in which a sufficient length of the running web is moved across the path of an oncoming mandrel or cigarette pack. A fresh web is threaded into the apparatus while the running web is being converted into a succession of blanks, and the leader of the fresh web is held at a preselected locus so that it can be moved into the range of the gripper as soon as the supply of running web is nearly exhausted. The apparatus then ceases to advance the running web and starts to advance the fresh web from the respective bobbin toward the locus where the leader of the fresh web can be engaged by the gripper. The leader of the expired web is moved out of the way not later than when the leader of the fresh web moves into the range of the gripper.
