Description

The invention relates to a machine of the tobacco processing industry for feeding a cigarette rod machine and a method for operating a machine of the tobacco processing industry for feeding a cigarette rod machine.

In the production of cigarettes in the tobacco processing industry, a distributor device is arranged upstream of the cigarette rod maker. The distributor device serves to meter the tobacco stream, which is usually supplied via an air stream, to sift and to form one or more tobacco strands from the sighted tobacco material which are fed to a downstream cigarette rod machine. Tobacco strands that are processed into cigarettes or the like usually consist of a tobacco blend of various tobacco components or varieties. The product stream required for the production of cigarettes is compiled and mixed in known methods before entering the distributor device. The tobacco stream is fed via an input device, which is usually formed from a feed lock, the distributor device. In addition, in the distributor device, the tobacco is sighted, singulated and then fed via a stowage shaft to a suction strand conveyor for forming one or more tobacco strands. In the sifter, the portions of the product stream suitable for further processing are separated from undesirable components, such as tobacco leaf ribs or foreign bodies. A distributor device is, for example, from EP 1 285 592 A2 known.

The raw material for the manufacture of tobacco products is often added reconditioned tobacco. This tobacco product is produced in a papermaking-like process or in a slurry process. The processed raw materials such as dust, tobacco leaf ribs and the like are by-produced during processing of the tobacco in the conventional process. Reconditioned tobacco is produced in the form of flat films and chopped for further processing, for example as an admixture with cigarette tobacco. The particles thus obtained are admixed, for example, in the primary of the tobacco mixture in a predetermined mixing ratio. Thus the reconditioned tobacco, together with the tobacco material obtained from tobacco leaves, also enters the strand formation.

It is an object of the invention to provide a novel machine of the tobacco processing industry for feeding a cigarette rod making machine and a novel method of operating such a machine.

The object is achieved by a machine of the tobacco processing industry for feeding a cigarette rod machine, which is developed by the fact that the machine as an input device for tobacco material to be processed comprises a storage for film-like flat reconditioned tobacco material, further comprising a crushing device downstream of the store arranged and adapted to process reconditioned tobacco material provided by the input device in a shredding process to tobacco small parts, and wherein the machine further comprises a conveying device, which is arranged downstream of the crushing device and adapted to the tobacco small parts to a Saugstrangförderer the cigarette rod machine to promote.

Advantageously, the machine of the tobacco processing industry processes the feedstock immediately upstream of the cigarette rod making machine without requiring further preparatory processing steps of the feedstock. This eliminates both the processing of the tobacco in the primary and the transport of the cut tobacco to the machine. The machine-processed reconditioned tobacco material has a high density, which is why the transportation and storage costs are low.

The machine of the tobacco processing industry for loading the cigarette rod making machine is much simpler than conventional distributors. For example, eliminating advantageously a pneumatic feed of the manifold, a correspondingly necessary lock, a sifter and a metering unit, such as a rotary valve.

In addition, unlike conventional distributors used in tobacco processing for feeding the cigarette rod machine, there is no further discharge of material, for example rib discharge from the rib sighting. The physical properties of the reconditioned tobacco material are very consistent and well controlled. As a result, the efficiency in the production of cigarettes is very high, for example, the rejection rate is very low.

It is also possible to specify flavors or blends directly in the preparation of the reconditioned tobacco material, so that a very constant production of, for example, a particular type of cigarette can be made. Are advantageous for the operation of the machine of the tobacco processing industry for loading the Cigarette rod machine no tobacco-specific knowledge required by the operator, since no tobacco-specific fine adjustments must be made. This is particularly advantageous for decentralized cigarette production.

The reconditioned tobacco material is preferably a tobacco-made tobacco sheet. The blending of the tobacco starting material has already been carried out in liquid form, for example by mixing different types of tobacco. This may optionally unwanted active ingredients or ingredients are extracted directly from the liquid mash, so as to optimize the composition of the tobacco smoke. The reconditioned tobacco material is thus a ready-to-use mixture which is fed directly to the strand formation.

In order to avoid degradation of the reconditioned tobacco material during transport, it is preferred that the reconditioned tobacco material be encapsulated during transport and storage, e.g. by wrapping in cling film. The required in conventional tobacco conditioning with respect to temperature and humidity can be advantageously eliminated.

According to an advantageous embodiment, the machine of the tobacco processing industry is developed in that the memory comprises a reel on which flat reconditioned tobacco material is rolled up.

It is provided in particular that the machine comprises a Bobinenwechselvorrichtung. The reel-to-reel device is further configured, in particular, to connect an outgoing end of reconditioned tobacco material coiled on a first reel to a beginning of reconditioned tobacco material coiled on a second reel. In other words, a change is made between the first reel and the second reel by means of the bobbin change apparatus, whereby this change does not interrupt production. Advantageously, continuously reconditioned tobacco material can be fed to the comminution device. A Bobinenwechselvorrichtung is for example in the EP 1 798 174 B1 described. The automation cell disclosed in this document for automated handling of the bobbins, for example, provided upstream of the crushing device. It is provided in particular that this automation cell is part of the machine of the tobacco-processing industry according to one embodiment.

It is provided in particular that the Bobinenwechselvorrichtung is adapted to a first bobbin on the flat reconditioned tobacco material of a first kind is rolled up against a second bobbin on the flat reconditioned tobacco material of a second variety is rolled, so that optionally reconditioned tobacco material the first kind or the second kind of the crushing device can be fed. In this way, a variety change is possible particularly easily and efficiently.

In this connection, according to a further embodiment, it is provided that the machine of the tobacco-processing industry is equipped with a processing unit, for example a microprocessor, a correspondingly equipped computer server or the like, and a signal relating to the processing speed of the cigarette machine is received at this processing unit. Depending on this signal, according to this embodiment, an unwinding speed of the reel, that is to say a speed with which the reconditioned tobacco material is supplied to the punching device, is controlled or regulated.

The provision of the reconditioned tobacco material on a reel, that is, rolled or wound on a reel, is advantageous, for example, in terms of handling, processing and storage.

The machine of the tobacco processing industry is further developed in that the crushing device is a punching device, in particular a roll punch, which comprises a punching roller and a mating roller cooperating therewith.

As an alternative to a roll punch, a bar cutter or the like can also be used. The advantage of a roll punch is that it ejects small parts of tobacco in a continuous process. A roll punch is often referred to as a roll punch.

The processing of the reconditioned tobacco material in a punching process, ie by means of the punching device, to tobacco small parts is particularly advantageous since during stamping little incidental material, such as small tobacco particles, dust or the like, incurred. In addition, the starting material, in this case the reconditioned tobacco material, is treated very gently. The punching process advantageously allows a free shaping of tobacco small parts. Possible shapes are, for example, polygons, for example rectangular strips. L-shaped particles or the like. It is also advantageous that punching is a continuous process.

According to an advantageous embodiment, it is provided that the punching roller and the counter-roller cooperate along a punching line, which is uneven across a feed plane in which the film-like flat reconditioned tobacco material can be fed to the punching device.

For example, the punching line is wavy. This bipolar rolling of the reconditioned tobacco material increases the volume of the manufactured tobacco small parts.

The shredding of the tobacco small parts is preferably carried out with a punching device. But it is also possible that instead of the punching device, a crushing device is used, which includes, for example, a longitudinal and a cross cutter.

According to a further advantageous embodiment, the machine is further developed in that the reconditioned tobacco material comprises two assembled individual layers of flat film-like reconditioned tobacco material, the two individual layers having different coefficients of thermal expansion.

The different coefficients of thermal expansion of the individual layers can be achieved, for example, by using different binders for producing the individual layers. One possible example is the use of guar gum or guar gum for the first single layer and the use of xanthan as the binder for the second single layer. By an effect, as it is known for example from a bimetal ago, the tobacco-small part curves under heat, so that the volume of tobacco small parts increases in total in the tobacco rod. Advantageously, tobacco material can be saved and gained in filling power. To enhance the effect, for example, a heating of the tobacco material may be provided.

According to a further embodiment, the machine is further developed in that the conveying device comprises a supply channel, which is free of internals, and along which the punched tobacco small parts are conveyed to the Saugstrangförderer the cigarette rod machine.

It is, for example, a curved supply channel, which initially has a free-fall path, with subsequent promotion of tobacco small parts, for example by suction, in the direction of strand formation. In particular, the conveying device does not comprise a lock, a separating device and a storage shaft, as known from conventional distributors. This greatly simplifies the construction of the machine.

According to a further embodiment, it is provided that the machine is set up to feed the cigarette rod machine exclusively with tobacco small parts punched out of the reconditioned tobacco material.

For example, the reel on which the reconditioned tobacco material is wound is adjusted to the width commonly used for a dispenser. As an alternative to a complete supply of strand production with tobacco small parts from reconditioned tobacco material, the so-called tobacco confetti, it is provided that the tobacco small parts are added directly into the distributor or in the stowage bay of a conventional cigarette rod making machine. The addition of reconditioned tobacco material directly into the distributor of the machine is for example in the EP 1 442 666 A1 described.

If the cigarette rod is formed exclusively from tobacco small parts that have been punched out of reconditioned tobacco material, this results in an extremely homogeneous tobacco rod. This has an advantageous effect on the head loss, weight, hardness, Abrauchwerte, taste and the like.

The object is also achieved by a method for operating a machine of the tobacco processing industry for feeding a cigarette rod machine, this method being developed by the machine having a memory as an input device for tobacco material to be processed, a comminution device arranged downstream of the store and a downstream one The method comprises the steps of: providing film-like flat reconditioned tobacco material in the store, feeding the reconditioned tobacco material from the store into the crusher, crushing the reconditioned tobacco material into tobacco mints, and conveying the tobacco mints in the shredder Conveyor to a Saugstrangförderer the cigarette rod machine.

The process has the same or similar advantages as already mentioned with regard to the machine of the tobacco processing industry.

In the context of the present description, the term "crushing" is understood to mean a process in which separate individual tobacco small parts are cut out or punched out, for example, from the sheet-like, flat-reconditioned tobacco material. The "tobacco confetti" produced in this way, more precisely the individual small tobacco parts, always have a limited spatial dimension. It is with the tobacco-small parts so especially not with endless fibers or stripes. Accordingly, the process of comminution is in particular not slitting of the sheet-like reconditioned tobacco material with the aim of producing endless fibers or strips.

According to an advantageous development, it is provided that the flat reconditioned tobacco material is rolled up on a reel and fed to the comminuting device by unwinding from the reel, wherein in particular a unwinding speed of the reconditioned tobacco material is controlled or regulated by the reel as a function of a production speed of the cigarette rod machine.

Another advantage is that, by controlling and / or regulating the unwinding speed of the reel, the amount of tobacco small parts produced from reconditioned tobacco material can be very accurately determined or regulated or metered. This has the advantage that it can be dispensed with trimming the tobacco in the strand molding. In other words, it is not necessary to work with surplus tobacco as is conventionally the case. This significantly increases the efficiency of the machine and the process.

By adjusting the unwinding speed to the speed of production of the cigarette machine, a particularly efficient production can be ensured. In this context, the method also includes, for example, a step in which a corresponding signal or data packet is received at the machine of the tobacco-processing industry, the value of which is a function of the production speed of the cigarette machine. Depending on this value, the unwinding speed of the reel is controlled.

The method is further developed, in particular, in that the machine comprises a reel-to-reel device and the reel-to-reel device connects an outgoing end of reconditioned tobacco material coiled on a first reel to a beginning of reconditioned tobacco material coiled on a second reel so as to continuously recondition tobacco material of the comminution device is supplied.

Advantageously, no interruption of the production process occurs.

According to a further embodiment, it is further provided that, when changing the type of cigarettes produced by the cigarette rod maker, a first bobbin on which flat reconditioned tobacco material of a first kind is rolled, with the bobbin changing apparatus against a second bobbin, on the flat reconditioned tobacco material of a second bobbin Variety is rolled up, is replaced, so that either reconditioned tobacco material of the first grade or the second variety of the punching device is supplied.

According to this embodiment, a particularly simple and rapid change from one type of cigarette to the next is possible. In addition, the inevitable occurring during a change waste is minimized.

According to a further advantageous embodiment, it is provided that the tobacco small parts are comminuted in a continuous process, in particular using a punching device, further in particular with a roll punch, which comprises a punching roller and a mating roller cooperating therewith.

In a continuous stamping process, only very few by-products, such as tobacco dust, are advantageously produced.

The method is further preferably developed by comminuting the sheet-like, reconditioned tobacco material in a roll punch to which the reconditioned tobacco material is fed in a feed plane and the stamping process is along a punch line that is uneven across the feed plane, such that it is uneven or curved Tobacco small parts are punched out.

In this way, it is possible to increase the volume of punched tobacco hardware.

The comminution of the reconditioned tobacco material preferably takes place in a stamping process. However, it is also possible that the reconditioned tobacco material is comminuted by longitudinal and transverse cutting.

In addition, it is provided in particular that reconditioned tobacco material which comprises two assembled individual layers of flat film-like reconditioned tobacco material, the punching device is supplied, wherein the two individual layers have different thermal expansion coefficients. In this connection, provision may also be made for the reconditioned tobacco material to be heated, in order to additionally increase or optimize a bending, twisting or the like of the punched tobacco small parts.

According to a further embodiment, it is further provided that the tobacco small parts of the crushing device without further process steps to undergo the processing in the Cigarette rod machine can be supplied. In this context, it is particularly provided that no further process steps, such as locks, dosing, damming the small tobacco parts or a separation of the same, take place.

In this runs, for example, a suction belt with which one or more tobacco strands are formed. The machine of the tobacco processing industry shown schematically and simplified in a cross section 2 comprises a memory as input device for tobacco material to be processed 6 for filmlike flat reconditioned tobacco material 8th , Furthermore, the machine includes 2 a crushing device 10 that are downstream of the store 6 is arranged. The crushing device 10 becomes the film-like flat reconditioned tobacco material 8th provided and in a shredding process to tobacco hardware 12 processed, for reasons of clarity, only a few are provided with reference numerals. The machine of the tobacco processing industry 2 for feeding the cigarette rod machine further comprises a conveying device 14 located downstream of the comminution device 10 is arranged. The conveyor 14 is set to the tobacco hardware 12 to the Saugstrangförderer 4 to promote the cigarette rod machine.

As a memory 6 includes the machine 2 for example, a bobbin 16 on which the flat reconditioned tobacco material 8th rolled up. Preferred is a Bobinenwechselvorrichtung 18 includes, for example, in the EP 1 798 174 B1 is described. This bobbin change device 18 is set to have an expiring finish from on a first reel 16 Coiled reconditioned tobacco material 8th with a start of on a second reel 20 Coiled reconditioned tobacco material 8th connect to. So it is advantageously possible that uninterrupted reconditioned tobacco material 8th the crushing device 10 can be fed. The from the EP 1 798 174 B1 known device for handling bobbins, which as Bobinenwechselvorrichtung 18 is to be designated, comprises an automation cell, which, for example, upstream of the crushing device 10 is arranged. A bobbin change device 18 is particularly advantageous when a brand change is to be performed. Such is the bobbin change device 18 in particular set up, optionally a first bobbin 16 or a second bobbin 20 so arrange that on each of the corresponding bobbins 16 . 20 existing flat reconditioned tobacco material 8th the crusher 10 can be supplied. The bobbin change device 18 For example, it is suitable for the first bobbin 16 , on the flat reconditioned tobacco material 8th rolled up a first kind, against a second bobbin 20 , on the flat reconditioned tobacco material 8th a second sort rolled up to exchange. So can optionally reconditioned tobacco material 8th the first variety or the second variety of the comminution device 10 be supplied. With the help of the Bobinenwechselvorrichtung 18 So it is very easy and fast brand change possible.

The shredding device 10 is for example a punching device. However, it is also provided that as a crushing device 10 a cutting device is present, for example a longitudinal and transverse cutter. In the illustrated embodiment, the punching device is a roll punch, which is a punching roll 22 and a cooperating with this counter-roller 24 includes.

The punching roller 22 includes a punching blade, for example made of carbon steel, which is designed so that the desired shape of the tobacco hardware 12 from the reconditioned tobacco material 8th is punched out. With the help of the punching device, it is possible to shape and size of the desired tobacco hardware 12 to set arbitrarily and thus adapt directly to the strand process in cigarette production. It may, for example, a desired size distribution of tobacco hardware 12 be set. That from the tobacco hardware 12 produced tobacco is very consistent and homogeneous. The size and quality of the tobacco hardware 12 virtually does not fluctuate since the reconditioned tobacco material 8th unlike tobacco leaves itself has virtually no fluctuations in terms of its properties, quality and the like. The stamping process is also advantageous because the reconditioned tobacco material 8th treated very gently and also virtually no by-products, such as tobacco dust arise. Further, it is advantageous that a change, for example, the punching roller 22 To get a different size or size distribution of the punched tobacco hardware 12 To achieve, very easily and quickly can be made.

The punching roller 22 and the counter roll 24 act along a punching line 26 together, across a feed plane 28 in which the flat reconditioned tobacco material 8th the punching device is supplied, is uneven.
