摘要:
A chain conveyor for the transport of mass flows of cigarettes or other rod-shaped commodities has a series of identical links which are articulately connected to each other by alternating vertical and horizontal chain pins. The upper portions of the vertical pins carry platforms having supporting surfaces for the commodities, and each vertical pin further carries roller followers serving to track vertically spaced-apart portions of a guide surface which can have one or more non-linear portions, such as convex portions. The leading and trailing portions of successive platforms are interdigitated in such a way that the supporting surfaces of neighboring platforms can be inclined relative to each other as well as that the supporting surfaces of neighboring platforms can turn relative to each other about the axes of the respective vertical pins. Portions of the horizontal pins can extend into a channel between the vertically spaced-apart portions of the guide surface.

The diameters of rod-shaped articles of the tobacco processing industry are ascertained while the articles are transported past a measuring station in the flutes of a drum-shaped conveyor moving along a range finder which measures the distance of each article of a series of articles from a reference point and transmits appropriate signals to an evaluating circuit wherein the diameters of successive articles are determined on the basis of comparison with a fixed reference distance of the bottoms of the flutes from the reference point. The beam of radiation which is emitted by the radiation source of the range finder is reflected by successive articles, and the intensity of reflected radiation is used to generate second signals which are processed into signals denoting a second diameter of each article. A third diameter of each article can be ascertained downstream of the range finder by an optoelectronic detector.

Apparatus for converting two parallel files of coaxial cigarettes into a single row of parallel pairs of coaxial cigarettes has a guide which delivers the two files of cigarettes from a twin cigarette maker and a first rotary conveyor with arms for pairs of flutes each of which removes a pair of coaxial cigarettes at a first transfer station. The pairs of cigarettes are transported, without a change of orientation, to a second transfer station between the first rotary conveyor and a second rotary conveyor. The latter has a first set of flutes at its peripheral surface and a second set of flutes on pivotable levers which can pivot the flutes of the second set away from and back toward the peripheral surface of the second conveyor. One flute of each pair of flutes on the first conveyor delivers a pair of cigarettes directly into a flute of the first set, and the other flute of each pair of flutes on the first conveyor delivers a pair of cigarettes into a flute of the second set. The flute of the second set is then pivoted toward the peripheral surface of the second conveyor and comes to rest between two flutes of the first set. The first conveyor transports pairs of cigarettes in a vertical plane.

Two parallel webs of wrapping material are advanced toward the inlet of a wrapping mechanism in a twin cigarette rod making, filter rod making or like machine adjacent a paster with two wheel-shaped rotary applicators which apply strips of adhesive to selected marginal portions of the respective webs. The applicators receive adhesive from discrete rotary adhesive supplying members which, in turn, receive adhesive from a tandem pump. The applicators are installed at a level below the wrapping mechanism to reduce the likelihood of contamination of such mechanism by sprays or droplets of adhesive. The webs are draped around discrete tobacco-containing or filter material-containing rods, and the adhesive-coated marginal portions of the webs are folded over the other marginal portions to form seams which extend in parallelism with the axes of the resulting cigarette rods or filter rods.

A first mass flow of rod-shaped articles of the tobacco processing industry is transported along a substantially horizontal path wherein the articles are moved sideways, and a second mass flow of articles is transported along a downwardly sloping path which makes with the horizontal path an acute angle and merges into the horizontal path at a junction zone wherein the flow of articles is controlled by a pivotable gate. The gate has a blocking surface which intercepts the articles of the mass flow in the horizontal or sloping path when the gate is moved to a first position, and at least one guide surface which controls the flow of articles in the first or second mass flow during advancement through the junction zone in the first position of the gate. The gate can be pivoted to a second position in which its blocking surface does not interfere with advancement of articles of both mass flows into, through and beyond the junction zone. The gate can be provided with a second guide surface which defines with the blocking surface and an adjacent wall a first-in last-out reservoir for surplus articles in another second position of the gate.
摘要:
A single stream of comminuted tobacco leaves is divided into two discrete streams each of which contains a surplus of tobacco particles. The surpluses are removed by discrete trimming devices and the thus removed surpluses are conveyed into the distributor which forms the single stream in such a way that the surplus which is removed from one of the discrete streams is reused for the making of a next-following portion of the one discrete stream or for the making of a next-following portion of the other discrete stream. The surplus which is removed from the other discrete stream is reused for the making of a next-following portion of the other discrete stream or for the making of a next following portion of the one discrete stream.
摘要:
A relatively wide first layer of tobacco particles is broken up into several narrower second and several narrower third layers. The second layers are converted into a first tobacco filler stream which is trimmed to form a rod-like filler ready to be draped into a web of cigarette paper, and the third layers are converted into a second tobacco filler stream which is ready to be trimmed to form a rod-like filler ready to be draped into a web of cigarette paper. The tobacco layers are caused to advance along and closely follow concave sides of guide surfaces and are propelled along the respective surfaces by streams of compressed air. Subdivision of the first layer into several second and several third layers reduces the likelihood of unmixing or dehomogenization of the mixtures of tobacco particles which are about to be converted into plural tobacco filler streams.
摘要:
The ratio of different types of tobacco in a tobacco stream which is conveyed past a trimming device is monitored by monitoring the distance of the trimming plan from the conveyor for the stream while the mass flow of the stream is maintained at a constant value. Variations of the distance of the trimming plane from the conveyor are indicative of variations of the ratio of different tobaccos in the stream, and such variations are further indicative of fluctuations of filling power of tobacco which forms the stream.
摘要:
A stream of filter tow which has been sprayed with atomized plasticizer is advanced past two detectors each of which monitors the density of the stream in a different way and generates corresponding signals which are processed by an evaluating circuit to generate modified signals which are indicative of the percentage of plasticizer. The modified signals are used to regulate the operation of a pump which controls the rate of admission of plasticizer to successive increments of the tow.
摘要:
A cigarette rod which is repeatedly severed by the orbiting knife of a cut-off is supported by a tubular guide which has a slot for the knife and is moved with the rod in the course of each severing operation to thereupon move back to a starting position. The guide is rigidly connected to and is moved back and forth by the head of a connecting rod which is driven by an eccentric pin and is fixedly connected to the upper end of a single leaf spring. The lower end of the leaf spring is affixed to a stationary support. The head of the connecting rod moves the guide forwardly while the pin advances along the lower portion of its circular path, and the internal surface of the guide is designed in such a way that it supports the rod from below during severing but is spaced apart from the rod during movement to starting position.
