Description

TECHNICAL FIELD The present invention relates to a machine of a tobacco processing industry for supplying raw materials to a tobacco rod forming machine and a method for operating the machine,

The present invention relates to a machine of a tobacco processing industry for raw material supply to a tobacco rod forming machine and a method for operating a machine of a tobacco processing industry for raw material supply to a tobacco rod forming machine.

In the tobacco processing, a distribution device is disposed upstream of the tobacco rod forming machine in the production of cigarettes. The dispensing device forms one or more tobacco rods fed to a tobacco rod-forming machine arranged rearwardly with a selected tobacco material, for dosing, sorting, and generally for the tobacco flow supplied by the air flow . Tobacco rods that are processed to form cigarettes or the like generally consist of various tobacco ingredients or a variety of tobacco mixtures. The product streams required for the manufacture of cigarettes are combined and mixed prior to entry into the dispensing device in an open process. The tobacco flow is generally supplied to the dispensing device by an injection device formed in a charge lock. In addition, in the dispensing device, the tobacco is selected, separated and provided to a load adsorption conveyor for the formation of one or more tobacco rods via a storage chute. Portions of the product stream suitable for further processing are separated from undesirable components such as for example tobacco leaves or external particles in the separator. A dispensing device is disclosed, for example, in EP 1 285 592 A1.

The reconditioned tobacco is repeatedly added to the starting material for the manufacture of tobacco. This tobacco product is produced by a process similar to the production of paper or by a suspension process (slurry process). For example, dust, tobacco leaves and such processed starting ingredients are produced as by-products during the processing of tobacco in conventional processes. The regenerated tobacco is produced in the form of a flat foil and is cut into small pieces as a mixture, for example, tobacco tobacco for further processing. The thus obtained pieces are mixed, for example, primarily in a tobacco mixture at a predetermined mixing ratio. Thus, regenerated tobacco is also introduced into the rod formation together with the tobacco material obtained from the tobacco leaves.

It is an object of the present invention to provide a novel machine of a tobacco processing industry for supplying a raw material to a tobacco rod forming machine and a novel method for operating such a machine.

The above object is achieved by a storage device for a tobacco-shaped flat-regenerated tobacco material as an injection device for a tobacco material to be machined by a machine of the tobacco processing, further comprising a grinding device, Wherein the machine further comprises a conveyor device, wherein the conveyor device is disposed downstream of the grinding device, and the tobacco-pieces To a load adsorption conveyor of a tobacco rod forming machine, the improvement being achieved by a machine of a tobacco processor for replenishing the raw material to a tobacco rod forming machine.

Preferably, the machine of the tobacco processing machine directly processes the starting material upstream of the tobacco rod forming machine, in which case other preparation steps of the starting material are unnecessary. This primarily eliminates the processing of the tobacco and the machine transport of the cut tobacco. Since the recycled tobacco material processed in the machine has a high density, the transportation and storage costs are low.

The machine of the tobacco processing for the supply of raw materials to the tobacco rod forming machine is much simpler than the conventional distributor. For example, preferably the pneumatic supply of the distributor, thus the necessary lock, sorter and dosing unit, for example a rotary valve, is also omitted.

In addition, unlike conventional dispensers used to distribute raw materials to tobacco rod forming machines during tobacco processing, there is no additional material discharge such as leaf vein discharge according to leaf vein sorting. The physical properties of the regenerated tobacco material are very constant and well controllable. This leads to a very high efficiency in the production of cigarettes, for example the rate of defects is very low.

Also, since it is possible to determine the direct taste and blending during the production of the regenerated tobacco material, for example, a very constant production of a particular tobacco species can be achieved. Preferably, tobacco-specific knowledge is not required for the operator to manipulate the machine of the tobacco processing machine for the supply of raw materials to the tobacco rod-forming machine, since the tobacco-specific fine tuning does not have to be done. This is particularly preferred for the production of dispersive cigarettes.

The regenerated tobacco material is preferably a tobacco foil produced during the paper process. Blending of the tobacco-starting materials was carried out in liquid form, for example by mixing various tobacco species. At this time, the composition of the tobacco smoke may be optimized since undesirable functional components or containing components may be extracted from the liquid slurry, as the case may be. The regenerative tobacco material is, for example, a ready-mix that is fed directly to the rod formation.

To prevent degradation of the regenerated tobacco material during transit, regenerated tobacco material is preferably encapsulated in wrapping and storage, for example in a cling film. Air conditioning associated with essential temperature and humidity in conventional tobacco can be preferably omitted.

According to a preferred embodiment, the machine of the tobacco processing industry is improved by winding the recycled tobacco material flat on the bobbin, the storage device comprising a bobbin.

In particular, it is contemplated that the machine includes a bobbin replacement device. The bobbin replacement device is also configured to connect the advancing end of the regenerated tobacco material wound on the first bobbin to the beginning of the regenerated tobacco material wound on the second bobbin. In other words, the replacement between the first bobbin and the second bobbin is made by a bobbin replacement device, in which case the replacement does not cause a production interruption. Preferably the uninterrupted regenerated tobacco material can be fed to the grinding apparatus. A bobbin replacement device is described, for example, in EP 1 798 174 B1. An automated cell for automated handling of the bobbin disclosed in the publication is provided upstream of the grinding apparatus, for example. In this case, in particular, such an automation cell is considered to be part of the machine of the tobacco processing according to the embodiment.

In particular, since the bobbin replacing device is configured to replace the first bobbin with the first type of flat regenerated tobacco material by the second bobbin with the second type of flat regenerated tobacco material wound, the first type or the second type of regeneration It is contemplated that the tobacco material may be supplied to the grinding apparatus. This makes it possible to change the type in a particularly simple and efficient manner.

In this regard, according to another embodiment, a processing unit, for example a microprocessor, a correspondingly designed computer server or the like, is installed in the machine of the tobacco processing industry, and a signal corresponding to the processing speed of the tobacco- Is received. Depending on the signal, the unroll rate of the bobbin, i. E. The rate at which the regenerated tobacco material is fed to the punching device, is controlled or adjusted according to this embodiment.

The provision of regenerated tobacco material on the bobbin, for example as a wound or wound material on rolls, is desirable, for example, in terms of handling, processing and storage.

The machine of the tobacco processing industry is also improved by including a punching device, in particular a rolling punch, wherein the rolling punch includes a punching roller and a counter roller which cooperates with the punching roller.

As an alternative to rolling punches, a carriage beam punch or the like may be used. An advantage of rolling punches is that the rolling punches eject the tobacco pieces in a continuous process. Rolling punches are often called roll punches.

Processing of the regenerated tobacco material with tobacco-pieces using, for example, a punching device in a punching process is particularly preferred because less tobacco pieces, dust or such by-products are produced during punching. Also, the starting material, in this case the regenerated tobacco material, is treated very carefully. The punching process preferably allows the free formation of the tobacco-pieces. Possible shapes are, for example, squares, for example rectangular strips, L-shaped pieces or the like. Also, punching is preferably a continuous process.

According to another refinement, the punching roller and the counter roller work together along the punching line, and the punching line is not flat in the transverse direction relative to the feeding plane in which foil-like flat regenerated tobacco material can be fed to the punching device.

For example, a punch line is a waveform. The amount of tobacco-pieces produced is increased by this anodic rolling of regenerated tobacco material.

The grinding of the tobacco-pieces is preferably carried out by a punching device. However, it is also possible, instead of a punching device, to use a grinding device, for example comprising a longitudinal- and transverse cutter.

According to another preferred embodiment, the machine is improved by having the regenerated tobacco material comprise two bonded individual layers of a flat foil-shaped regenerated tobacco material, the two individual layers having different thermal expansion coefficients.

The different thermal expansion coefficients of the individual layers can be achieved, for example, by using different binders for the production of the individual layers. A possible example is the use of guar flour or guar gum as the binder for the first individual layer and the use of xanthan for the second individual layer. For example, due to the effect released from the bimetal, the tobacco-pieces are bent under heat, so the amount of tobacco pieces in the tobacco stick increases overall. Preferably the tobacco material can be saved and filling power can be obtained. To enhance the effect, for example heating of the tobacco material can be considered.

According to another embodiment, the machine is characterized in that the conveyor device comprises a feed channel, the feed channel does not include an assembly, and the punched tobacco-pieces can be transported along the channel to the load adsorption conveyor of the tobacco rod forming machine Lt; / RTI >

For example, of course, curved feed channels having a free fall interval are involved, in which case subsequent transport of tobacco-pieces takes place in the direction of rod formation, for example by suction air. In particular, conveyor devices do not include locks, sorting devices and storage chutes as disclosed from conventional distributors. This greatly simplifies the construction of the machine.

According to another embodiment, it is contemplated that the machine is configured to dispense only tobacco-pieces punched from the recycled tobacco material in the tobacco rod-forming machine.

For example, a bobbin on which a regenerated tobacco material is wound is generally adapted to the width used for the dispenser. As an alternative to the overall supply of tobacco pieces obtained from the regenerated tobacco material, so-called tobacco-confetti, tobacco-pieces are provided directly to the distributor or storage chute of a conventional machine for the production of tobacco rods . The addition of direct-regenerating tobacco material into the dispenser of the machine is described, for example, in EP 1 442 666 A1.

When the tobacco rod is formed of only punched tobacco pieces from the regenerated tobacco material, a very uniform tobacco rod is obtained. This works well for head loss, weight, hardness, smoke value, taste, and the like.

The above object is also solved by a method for operating a machine of a tobacco processing industry for the supply of raw materials to a tobacco rod forming machine, the method comprising the steps of: providing a storage device as an injection device for the tobacco material to be machined, The method comprising the steps of: providing a storage device with a flat regenerated tobacco material in the form of a foil; transferring the recycled tobacco material from the storage device into the grinding device Feeding the regenerated tobacco material, pulverizing the regenerated tobacco material into tobacco-pieces, and transferring the tobacco-pieces from the conveyor apparatus to the rod adsorption conveyor of the tobacco rod forming machine.

The same or similar advantages as described above with respect to the machine of the tobacco processing apply to the method.

In the context of the present disclosure, "pulverization" is a process wherein separate individual tobacco-pieces are cut or punched, for example, from a foil-shaped, recycled tobacco material. The "tobacco-confetti ", or precisely the individual tobacco pieces produced thereby, always have a spatially limited dimension. Tobacco-pieces are not particularly infinite fibers or strips, for example. Therefore, the milling process is not related to the longitudinal cutting of the foil-like flattened regenerated tobacco material for the purpose of forming infinite fibers or strips.

According to a preferred refinement, it is contemplated that a flat regenerated tobacco material is wound on a bobbin and fed to the grinding apparatus by unwinding from the bobbin, in which case the speed at which the regenerated tobacco material is unwound, in particular from the bobbin, depends on the production rate of the tobacco rod- To be controlled or adjusted.

Another advantage is that the discharge amount of the tobacco pieces made of the regenerated tobacco material can be determined very accurately or can be adjusted or dosed by controlling and / or controlling the unwinding speed of the bobbin. This provides the advantage that trimming of the tobacco during the formation of the rod can be omitted. In other words, it is not necessary to process excessive-tobacco as in the prior art. This significantly increases the efficiency of the machine and method.

By ensuring that the release rate is adapted to the production rate of the tobacco-forming machine, particularly efficient production can be ensured. In this regard, the method also includes, for example, receiving a corresponding signal or data packet in a machine of the tobacco processor, wherein the value of the data packet is a function of the rate of production of the machine. The releasing speed of the bobbin is controlled depending on the value.

The method is also particularly suitable because the machine includes a bobbin replacement device and the proximal end of the regenerative tobacco material wound on the first bobbin by the bobbin replacement device is connected to the beginning of the regenerated tobacco material wound on the second bobbin, And the tobacco material is supplied to the grinding apparatus.

Preferably, no interruption of the production process occurs.

In accordance with another embodiment, a first bobbin of a first type of flat regenerated tobacco material wound upon replacement of a type of cigarette produced by a tobacco rod forming machine is wound by a bobbin replacement device of a second type of flat regenerated tobacco material wound It is considered that the first type or the second kind of regenerated tobacco material is selectively supplied to the punching device.

According to the embodiment, a particularly simple and quick replacement is possible from one cigarette type to the next cigarette type. In addition, defective products that occur inevitably during replacement are minimized.

According to another preferred embodiment, the tobacco pieces are comminuted in a continuous process, in particular by means of a punching device, and in particular by a rolling punch, the rolling punch comprising a punching roller and a counter roller acting therewith. During the continuous punching process, preferably only very small by-products, for example tobacco dust, are produced.

The method is also preferably carried out in such a manner that the tobacco-like flat regenerated tobacco material is pulverized in a rolling punch, the regenerating tobacco material is fed to the rolling punch at a feed plane, the punching process is carried out along a punching line, The flat or bent tobacco-pieces are improved by being knitted.

This makes it possible to increase the amount of punched tobacco-pieces.

The pulverization of the regenerated tobacco material is preferably carried out in a punching step. However, it is also possible for the regenerated tobacco material to be pulverized by longitudinal and transverse cutting.

It is also contemplated that, in particular, a regenerated tobacco material comprising two separate bonded layers of a flat foil type of regenerated tobacco material is fed to the punching device, and the two individual layers have different thermal expansion coefficients. In this regard, it may also be considered that the regenerated tobacco material is heated to further increase or maximize the warpage, twist or the like of the punched tobacco pieces.

According to another embodiment, it is also contemplated that the tobacco-pieces are fed from the grinding apparatus to the process in the tobacco rod forming machine, without further processing steps. In this regard, it is contemplated that, in particular, additional process steps such as locking, dosing, storing, or classifying the tobacco-pieces are not performed.

Other features of the invention are seen in the description of the embodiments according to the invention in connection with the claims and the accompanying drawings. Embodiments in accordance with the present invention can realize individual features or a combination of multiple features.

Figure 3 shows a reconstituted tobacco material consisting of two separate layers and tobacco pieces made therefrom.

Since the same reference numerals are given to members and / or parts of the same or the same kind in the drawings, repetitive explanations are omitted, respectively.

Fig. 1 shows a machine 2 of a tobacco processing industry for material supply to a cigarette rod forming machine not shown in Fig. Also shown is a load adsorption conveyor 4 of a tobacco rod forming machine, not shown. In the rod adsorption conveyor, for example, the adsorption tape is extended, and at least one tobacco rod is formed by the adsorption tape. The machine 2 of the tobacco processing shown schematically in simplified cross-sectional view comprises a storage device 6 for a recycled tobacco material 8 in the form of a foil as an injection device for the tobacco material to be machined. The machine 2 also includes a grinding device 10, which is disposed downstream of the storage device 6. The pulverizing device 10 is provided with a foil-shaped regenerated tobacco material 8 which is processed in a pulverizing process to form tobacco-pieces 12, in which only a few pieces / RTI > The machine (2) of the tobacco processing industry for the supply of raw materials to the tobacco rod forming machine also comprises a conveyor device (14), which is disposed downstream of the crusher device (10). The conveyor apparatus 14 is configured to transport the tobacco-pieces 12 to the load adsorption conveyor 4 of the tobacco rod forming machine.

As a storage device 6, the machine 2 comprises, for example, a bobbin 16, which is wound on a flat regenerated tobacco material 8 on the bobbin. Preferably, a bobbin replacing device 18 is provided, for example as described in EP 1 798 174 B1. The bobbin replacing device 18 is configured to connect the advancing end of the regenerated tobacco material 8 wound on the first bobbin 16 to the beginning of the regenerated tobacco material 8 wound on the second bobbin 20. Therefore, it is preferable that the uninterrupted regenerative tobacco material 8 can be supplied to the pulverizing apparatus 10, preferably. An apparatus for handling bobbins disclosed in EP 1 798 174 B1, also referred to as a bobbin replacing device 18, comprises an automation cell, which is arranged, for example, upstream of the mill 10. The bobbin replacing device 18 is particularly preferable when a brand change has to be performed. The bobbin replacing device 18 is thus arranged so that the first bobbin 16 or the first bobbin 16 can be selectively moved so that each flat regenerated tobacco material 8 provided in the corresponding bobbin 16, Two bobbins 20 are arranged. The bobbin replacing device 18 may comprise a first bobbin 16 wound with a first type of flat regenerated tobacco material 8 and a second bobbin 20 wound with a second type of flat regenerated tobacco material 8, . Therefore, the first type or the second kind of regenerating tobacco material 8 can be selectively supplied to the pulverizing device 10. [ Namely, the bobbin replacing device 18 can perform brand replacement very simply and quickly.

The pulverizing apparatus 10 is, for example, a punching apparatus. However, it is also contemplated that the grinding apparatus 10 is provided with a cutting device, for example a longitudinal- and transverse cutter. In the illustrated embodiment, the punching device is a rolling punch and the rolling punch includes a punching roller 22 and a counter roller 24 acting therewith.

The punching roller 22 comprises, for example, a punching knife made of carbon steel, which is formed such that a predetermined shape of the tobacco-pieces 12 is punched out of the regenerated tobacco material 8. By the punching device, it is possible to arbitrarily set the shape and size of the predetermined tobacco pieces 12 to directly fit the extrusion process in the production of the cigarette. For example, a predetermined particle size distribution of the tobacco-pieces 12 may be set. The tobacco product made from the tobacco-pieces 12 is very uniform and uniform. The size and quality of the tobacco-pieces 12 do not really change because the recycled tobacco material 8 does not actually vary in terms of its properties, quality and such, unlike the tobacco leaves. In addition, the extrusion process is preferred because the regenerated tobacco material 8 is treated very carefully and by-products such as for example tobacco dust are not actually formed. Also, preferably, to achieve different sizes or particle size distributions of the punched tobacco-pieces 12, for example replacement of the punching roller 22 can be carried out very simply and quickly.

The punching roller 22 and the counter roller 24 cooperate along the punching line 26 and the punching line extends in the transverse direction relative to the feeding plane 28 where the flat regenerated tobacco material 8 is fed to the punching device It is not flat.

2 shows punching rollers 22 and counter rollers 24 that are illustratively rotatable about a rotational axis shown by a dotted line, respectively. The direction of orientation of the pair of rollers faces the feed plane 28 shown in dash-dotted lines. The punching line 26 lies in the paper plane in this figure and extends between or at the surfaces of the punching roller 22 and the counter roller 24. The direction extending in the transverse direction relative to the feed plane 28 is likewise in the paper plane, and the punching line 26 in the feed plane is not planar and in the example shown is a waveform.

The outer surfaces of the rollers 22 and 24 are contoured so that the regenerating tobacco material 8 guided between the rollers 22 and 24 along the feed plane 28 is deformed during the punching process. The resulting tobacco pieces 12 are warped, which increases the amount of tobacco product thus produced with the tobacco-pieces 12.

The regenerating tobacco material 8 consists of two separate layers, for example, joined together. Figure 3 shows this regenerated tobacco material 8 in a schematic and simplified cross-sectional view.

The first individual layer 30 has a first temperature coefficient of expansion, for example, and the second individual layer 32 has a second coefficient of thermal expansion. If the second individual layer 32 has a larger coefficient of thermal expansion, it is possible to prevent the tobacco particles 12 punched out from this regenerated tobacco material 8 from being subjected to heat treatment schematically indicated by arrows, Deformation or warping of the tobacco-pieces 12 is achieved as shown. This deflection also increases the amount of tobacco articles made with the tobacco-pieces 12.

The conveyor apparatus 14 of the machine 2 of the tobacco processing shown in Fig. 1 for the supply of raw materials to the cigarette rod forming machine comprises a supply channel 34, which does not include an assembly. Through the feed channel 34, the tobacco pieces 12 can be transported to a load adsorption conveyor 4 of a tobacco rod forming machine, not shown. A locking, dosing unit, sorting device, storage chute or the like is not provided in the conveyor device 14 or in the feed channel 34. The tobacco-pieces 12 descend into the curved lower region of the feed channel along the free fall section and are conveyed toward the rod adsorption conveyor 4 in a compressed air manner, for example, using a nozzle 36.

The machine 2 of the tobacco processing industry is particularly configured so that only the tobacco pieces 12 made of the recycled tobacco material 8 are supplied to the tobacco rod forming machine. In other words, the tobacco rod produced by the tobacco rod-forming machine consists only of, for example, punched tobacco-pieces 12.

The unwinding speed of the bobbin 16 on which the regenerating tobacco material 8 is wound is adjusted to, for example, the production speed of the tobacco rod forming machine. The same applies to the processing speed of the grinding apparatus 10. Thus, the tobacco rod forming machine is always provided with the required amount of tobacco-pieces 12, ensuring optimal rod formation.

All of the above-described features, of course, are considered to be important to the invention, alone and in combination, of the individual features identified singularly and in combination with other features of the drawings. The embodiments according to the present invention can be realized by individual features or by a combination of a plurality of features. Features that are characterized as "particularly" or "preferably" in the scope of the present invention may be identified as certain features.
