摘要:
Cigarettes which are discharged lengthwise from the cutoff of a rod cigarette machine are fed into successive flutes of a revolving drum and are arrested and located in predetermined axial positions by forces produced by two or more streams of compressed air and/or suction air. The resultant of forces acting upon a cigarette in predetermined position is zero. A stationary shroud seals from the atmosphere the outer sides of those flutes which receive cigarettes from the cutoff and while the cigarettes in such flutes are acted upon to assume predetermined positions. Each cigarette can be biased against the adjoining surface of the respective flute by atmospheric air which is admitted through openings provided in the shroud.

Bronze powder is applied to adhesive at the underside of a travelling web of cigarette paper by a pile on the periphery of a transfer roller receiving a thin layer of bronze powder from a conveyor which draws or receives a constant supply of powder from an intermediate supply. The latter is replenished from a main supply by a further conveyor.

The wrappers of cigarettes are tested for a first time prior to and for a second time subsequent to the making therein of perforations by means of needles along which the wrappers roll during travel of cigarettes between a first and a second testing station. Cigarettes with defective wrappers are segregated after each testing operation or at a common ejecting location downstream of the second testing station.

Cigarette packs are transported by the upper stretch of a first belt to move into the range of a pneumatic overhead conveyor which transfers some or all of the packs onto one or more additional belts. The pneumatic conveyor has an apertured disk which is driven at a constant speed and rotates at a level above the first belt so that a portion of the disk overlaps the path of oncoming packs. The disk rotates below one or more suction chambers at least one of which is normally disconnected from and can be connected to a suction generating device when a selected pack reaches the disk whereby the disk cooperates with the suction chamber to lift the selected pack off the first belt and to transfer it onto another belt. The selection is made by a circuit employing a detector which is adjacent to the first belt and serves to produce signals in response to detection of defective packs or in response to detection of each pack whereby a timer circuit energizes the solenoid of a valve which controls the evacuation of air from a suction chamber above the revolving disk to effect the transfer of each second or third, etc. pack onto a second belt and the transfer of all other packs onto a third belt.

A cutting apparatus for subdividing webs of paper, metallic foil or synthetic plastic material into blanks or uniting bands for use in tobacco processing machines has an intermittently driven hollow drum which is open at one end and is formed with two openings located diametrically opposite each other. The external surface of the drum attracts by suction the leading end of a web which is being withdrawn from a bobbin. A stationary blade is mounted externally of the drum and a second blade is mounted in the interior of the drum opposite the stationary blade. When the drum is at a standstill, one of its openings (which is then overlapped by the leading end of the web to be severed) is located between the two blades. The second blade is then caused (either by an electromagnet or by a rotary cam) to move relative to the stationary blade whereby the cutting edges of the blades cooperate to sever the web overlying that opening which is located between the blades.
摘要:
A cigarette packing machine wherein empty packs or their component parts are withdrawn from the respective magazines only when a detector determines the presence of a block of cigarettes which are being transported to a pack filling station. The detector then causes the transfer of a prefabricated empty pack from its magazine to the filling station or the conversion of one or more blanks into an empty pack and the transfer of such pack to the filling station. Each block of cigarettes is introduced into and enclosed in that pack whose transfer from the magazine to the filling station or whose making from one or more blanks was initiated in response to detection of the particular block.

A distributor for tobacco shreds in a cigarette rod making machine employs a system of conveyors which transport a continuous wide layer of tobacco shreds from a magazine toward a channel wherein the shreds form a narrow tobacco stream. A pivotable baffle extends across the path of the layer and a rotary brush or a rapidly moving endless apron propels the shreds of successive increments of the layer at a constant speed against the baffle whereby a potentiometer whose sliding contact shares the movement of the baffle produces signals whose intensity varies as a function of changes in the quantity of shreds per unit length of the layer. The thus obtained signals are used to change the rate of withdrawal of tobacco shreds from the magazine or to intercept a larger or smaller percentage of shreds which are being propelled toward the baffle. The main prime mover of the cigarette rod making machine can be operated at several speeds, and a compensating circuit is provided to prevent the potentiometer from changing the rate of tobacoo feed into the channel in response to changes in operating speed of the prime mover.
摘要:
A packing machine wherein blocks of cigarettes are wrapped to form packs and/or wherein cigarette packs are provided with transparent outer envelopes comprises intermittently operated conveyors for envelopes and their contents. The conversion of tinfoil, paper and/or transparent plastic blanks into envelopes involves a series of treatments including one or more treatments each of which can be completed within a first period whose length equals the sum of an interval of stepwise movement and an interval of dwell of the respective conveyor, and one or more second treatments each of which can be completed within a longer second period. When the machine receives a stop signal, its operation continues until after the completion of a treatment which is in progress when the stop signal is being produced, regardless of whether the started treatment is a first or a second treatment. Consequently, all blanks which undergo treatment at the time a stop signal is being produced are processed to a degree which is necessary to insure that such blanks need not be discarded when the machine is started again.

Cigarettes or like rod-shaped smoking articles are introduced into and sealed in packs by withdrawing them from a magazine, moving the thus withdrawn articles sideways and assembling moving articles into block-shaped groups, converting blanks of sheet material into open-ended packs which thereupon receive groups of articles, and sealing the open ends of successive packs.
摘要:
Apparatus for segregating relatively light shredded tobacco leaf laminae from heavier particles of tobacco ribs and stem has a feeding device which showers a mixture of lighter and heavier particles onto the upper stretch of a rapidly moving classifying belt which propels the particles beyond one of its ends whereby the heavier particles are segregated from lighter particles because their flight span is longer than that of the shreds. The lighter particles are thereupon spread apart by a battery of horizontal winnowers of rectangular cross-sectional outline which distribute such particles on the upper stretch of a collecting belt which moves counter to the direction of travel of the upper stretch of the classifying belt. The feeding device has a carded belt which transports a sliver of intermixed lighter and heavier particles and from which a picker roller removes successive increments of the sliver to shower the particles onto the upper stretch of the classifying belt. The heavier particles are collected in a trough and are evacuated by a rotating screw.
