DEVICE AND METHOD FOR CONDITIONING A TOBACCO MIXING AND / OR STORAGE DEVICE

description

The invention relates to an apparatus and a method for conditioning at least one product receiving space, in particular a tobacco receiving space, or of a product, in particular tobacco, in at least one receiving space of at least one mixing and / or storage device for mixing and / or Caching the product, especially tobacco.

In the tobacco industry or in the production of tobacco products such as cigarettes, facilities for temporarily storing and possibly additionally mixing tobacco, in particular sheet goods, cut tobacco, ribs, rib cuts, etc., are known, which are also used as blending and / or storage boxes (blending and storage silos). These storage devices comprise a box-shaped receiving space and a Tabakzuführeinrichtung, which usually comprises a conveyor belt or a Flachgurtförderer, at the bottom of the receiving space another belt or belt conveyor and arranged in a conveying direction of this bottom conveyor at the end of the receiving space discharge devices such as Auskämmwalzen or a attached vertical conveyor.

In a storage box used only for temporary storage, the feeding device is generally uniformly charged over the width of the receiving space or perpendicular to the conveying direction of the bottom conveyor by moving the feeding device perpendicular to the conveying direction of the bottom conveyor or in the direction of the width of the box.

In a mixing box, the position of the feeder or the sprinkling of the tobacco is changed at least in the longitudinal direction or to and For example, by means of a mixing trolley oscillating above the mixing trough or receiving space, consisting of trolley and flat belt conveyor, so that a uniform tobacco infusion or feeding over the full length and width of the mixing box is achieved. The feeding device can sprinkle the tobacco over an oscillating conveyor trough with an oblique discharge to the full width of the mixing conveyor belt and from there the full length of the mixing box or convey it in strands to the mixing conveyor belt and into the mixing box via a stepping conveyor.

In many tobacco products, especially cigarettes, it is necessary to put them together from different tobaccos, with a uniform mixture of different tobaccos is required. For this reason, the mixing carriage or the feeding device reciprocating over the receiving space is correspondingly controlled in order to achieve as even as possible a loading of the intermediate storage or the mixing box with tobacco layers of different types of tobacco.

From DE 197 49 933 C2 a device for feeding a buffer, in particular a Rippenschnittbox, with tobacco layers known with a arranged on the buffer, in the longitudinal direction of the buffer reciprocable mixing wagon, the tobacco is constantly fed and from the discharge end a continuous stream of tobacco falls down into the buffer, and with a arranged at the bottom of the buffer storage conveyor for the further transport of the tobacco mass in the buffer to a doser. There are now web-like separation devices in the falling section of the tobacco between the mixing truck and the buffer for deflecting the falling tobacco stream provided so that form under the separation means predetermined breaking points in the tobacco mass and thereby separable, vertical tobacco columns arise. The bridge-like

Separating devices are in particular formed by two interconnected strips, which have the shape of a pointed roof in a side view with a horizontal base area of about 30 to 200 mm and a height of 30 to 120 mm, wherein the stegattigen separators are arranged at a distance of 30 to 60 cm from each other. The mixing cart has rollers that run on rails in a frame, as well as a conveyor belt with edge strips.

In such tobacco blending and / or storage systems in tobacco production, it is very important to comply with given process conditions for the processing and quality of the tobacco. Important process conditions are, in particular, the temperature and the moisture content of the tobacco. In order to keep the tobacco temperature and tobacco moisture within specified tolerances, the temperature and the humidity of the ambient air in the production hall are controlled by a central air conditioning system, whereby each mixing and / or storage box is ideally supplied with the same conditioned ambient air. However, such a central regulation is limited with regard to the accuracy of the conditioning of the tobacco in the individual mixing and / or storage boxes.

The invention is based on the object, a new device ud a new method for conditioning a tobacco receiving space or tobacco in at least one tobacco receiving space at least one mixing and / or storage device for mixing and / or temporary storage of tobacco in the tobacco processing industry or to indicate in the manufacture of tobacco products such as cigarettes.

This object is achieved with regard to the device with the features of claim 1 and with regard to the method with the features of claim 26.

Advantageous embodiments and further developments of the device according to the invention will become apparent from the dependent claims of claim 1. The invention is based on the consideration, for conditioning of at least one tobacco receiving space or tobacco in at least one tobacco receiving space of a mixing and / or Sp eicher device for mixing and / or temporary storage of tobacco in the tobacco processing industry targeted and immediately the receiving space or to act on the tobacco located in the receiving space with a conditioning gas flow of a conditioning device individually assigned to this receiving space and not, as in the prior art, to air-condition only the entire ambient air in the production hall. As a result, not only the temperature and / or the humidity of the tobacco can be set very precisely and without major influence on other areas in the production hall, in contrast to the prior art, but also other conditioning parameters, such as even the gas composition of the conditioning gas, can be set. which is not possible in the prior art.

The invention according to claim 1 and claim 26 is further based on the consideration that the device or its conditioning device or the method according to the invention can also be used to condition other products to be stored and / or mixed, e.g. Food and / or bulk materials other than tobacco applicable or usable.

The invention will be explained below with reference to exemplary embodiments. Reference is made to the drawings. Each shows in a schematic representation:

Corresponding parts and sizes are provided in the Figures 1 to 11 with the same reference numerals.

The memory device 2 in the embodiment according to FIGS. 1 and 2 as well as in the embodiment according to FIGS. 3 to 5 comprises an elongated or box-shaped receiving space 20 enclosed by a wall 21 for receiving and temporarily storing tobacco T prior to its further processing in a tobacco production plant, in particular FIG the cigarette production. The receiving space 20 with the wall 21 rests on a carrier 22, which is placed on the floor 10 einet production hall. In the bottom area of the receiving space 20, a conveyor 4, for example, a conveyor belt or belt conveyor, arranged with the tobacco T in the receiving space 20 in a conveying direction F can be conveyed out of the receiving space 20 depending on the desired quantities for the further processing and acceptance times. An end region of the storage device 2 located opposite to the conveying direction F "upstream" is designated by 2A and the "downstream" end region to which the tobacco T is transported by means of the conveying device 4 and leaves the receiving space 20 is designated by 2B. A combing or gripping device or a combing or gripping roller and / or a vertical conveyor through which the tobacco T is guided can also be arranged at the outlet end region 2B.

Upwards, the wall 21 is open, so that the receiving space 20 is accessible from above. Above the wall 21 of the receiving space 20, a supply device 3 for supplying tobacco T, which may likewise comprise at least one conveyor belt or a belt conveyor, is disposed at the upstream end region 2A. The tobacco T drops from the feed device 3 down into the receiving space 20. In order to achieve a uniform distribution across the width perpendicular to the conveying direction F in the receiving space, the feeder 3, as indicated by the arrows shown, transversely to the conveying direction F. is displaceable in a direction of displacement R and, as shown in FIGS. 1 and 2 or FIGS. 3 and 4, is continuously moved in different positions across the width of the receiving space 20, so that the tobacco T is distributed uniformly over the width in the receiving space 20.

Such a storage means for caching tobacco is similarly known in the art and is commonly referred to as a storage box or storage silo, so that further detailed descriptions are not required. The tobacco T must be conditioned during the temporary storage in the receiving space 20 of the storage device 2 under predetermined conditions in order not to suffer any deterioration in the quality, in particular the processing quality of the tobacco or even to improve the quality, in particular the processing quality, of the tobacco.

Therefore, by supplying conditioned air or conditioning air L by means of a conditioning device 5, the receiving space 20 or the tobacco T is conditioned in the receiving space 20 of the storage device 2 with respect to at least one conditioning amount. The conditioning variable used is in particular the tobacco temperature and / or the tobacco moisture and / or the air temperature and / or the air humidity.

One or more temperature sensors 25 measure the air temperature of the conditioning air L and one or more humidity sensors 26, the humidity of the conditioning air L between the tobacco T or the receiving space 20 on the one hand and the conditioner 5 on the other. The measured values are used to control the temperature and humidity conditioning variables of tobacco T or air L, as will be described below.

The conditioning device 5 in the imple mentation form according to FIG 1 and 2 comprises two parallel to each other in the longitudinal direction of the receiving space 20 or the conveying direction F extending feed channels 15 and 16, between which, in the examples of Figures 2 and 4 each seven, cross struts as web-like Air outlet 51 to 57 in FIG 2 and 51 'to 57' in FIG 4 run. The two supply channels 15 and 16 are connected in parallel to a supply line 6, is fed via the conditioning air L. The supply line 6 is connected to a conditioning unit 7, which generates the conditioned air L with predetermined values of conditioning variables of the air L, in particular temperature and / or humidity. The conditioning unit 7 is preferably arranged directly at the storage device 2, in particular below the support frame 22, and / or integrated with the storage device 2 to form a structural unit or in a common housing in order to keep the conduction paths short. The conditioning unit 7 can also be arranged further away.

The air outlet elements 51 to 57 or 51 'to 57' are arranged above the receiving space 20 or the tobacco T therein, typically at a comparatively small distance, and have outlet openings 20 directed towards the outlet of the conditioning air L to the receiving space 20 Tobacco T out, which are not shown in FIG 1 to 5, however, can be seen in the enlargement of FIG 6 and are designated there by 47. The distance of the air outlet elements or their outlet openings (47) amounts in an advantageous embodiment to the tobacco surface of the tobacco T at maximum filling or to the top of the receiving space 20 between 10 centimeters (cm) and 1.50 meters (m), in particular between 30 cm and 70 cm, for example 50 cm. With a lower filling, the distance to the tobacco surface T is correspondingly greater, and in addition to the height of the receiving space 20. The air outlet elements 51 to 57 or 51 'to 57' are arranged parallel to one another in FIGS. 2 and 4 at the same distance a in the conveying direction F.

The conditioning air L now flows from the outlet elements 51 to 57 or 51 'to 57' to the tobacco T and now conditions at least one conditioner size of the tobacco T, preferably the tobacco temperature T or

Moisture of the tobacco T, in particular by means of the air temperature and / or the humidity, or the conditioning air L itself, in particular their temperature and / or humidity.

Through these measures, a direct and unambiguous conditioning of the receiving space 20 or of the tobacco T by the conditioning device 5 is possible. The essential difference between the embodiment of the conditioning device 5 according to FIGS. 1 and 2 on the one hand and the embodiment according to FIGS. 3 to 5 on the other hand is essentially that the feed channels 15, 16 in FIGS. 1 and 2 are outside the wall 21 of FIG Storage device 2 are arranged and thus the transverse outer elements 51 to 57 are performed by the wall 21 and that in contrast to the imple mentation shape according to FIG 3 to 5, the flow channels 15, 16 are disposed within the wall 21 above the receiving space 20 , The outlet elements 51 to 57 according to FIGS. 1 and 2 are therefore longer than the outlet elements 51 'to 57' with the same width of the wall 21 or of the receiving space 20.

The outlet elements 51 to 57 and 51 'to 57' are preferably connected on both sides in terms of flow both with the flow channel 15 and with the flow channel 16, so that from both sides conditioning air L in the Luftauslasselemente 51 to 57 and 51 'to 57 'can flow. However, it is also possible to allow a flow only in one direction and thus to establish a flow connection only to one of the flow channels 15 or 16. Furthermore, it is also possible to make the flow connection of the individual air outlet elements 51 to 57 or 51 'to 57' controllable to the flow channels 15 and 16, for example by louvers or other controllable closure elements, so that the individual air outlet elements 51 to 57 or 51 'to 57' can be controlled individually either by the flow rate or also, or even completely switched on or off. The outlet elements 51 to 57 can also be separated into two flow spaces, for example by a closure in the middle thereof, so that a part of the outlet elements is flowed through by a flow channel 15 and the other part by the other flow channel 16 of the conditioning device 5.

In addition, the number, arrangement and design of the outlet elements can also be designed differently, for example in the manner of a grid structure with additional longitudinal struts or channels or with obliquely extending struts, as shown in FIG 8 by the example of a mixing device, possibly again in a lattice structure with oblique struts, or with, in particular down and / or to the side, curved outlet elements. The arrangement of the outlet openings on the outlet elements and their design can be varied within wide limits.

An embodiment for the design of the outlet elements is shown by way of example with reference to the outlet element 57 'or 57 in FIG. 6. The air outlet element 57 'has on its upper side two inclined wall surfaces 31 and 32, which meet at the top in a ridge or ridge 33 at an angle α. The angle α is set in the illustrated embodiment to 60 °, which corresponds to the angle of repose of tobacco, so that on the top 33 and the inclined surfaces 31 and 32 no tobacco T can settle or deposit. Subsequent to the inclined surfaces 31 and 32, respectively vertically extending side walls 34 and 35 are provided, on the underside thereof, for example, in a fold or flanging a bottom plate or bottom wall 38 is attached and the above connected via a transverse or horizontally extending intermediate plate 36 are. The intermediate plate 36 is formed as a perforated plate with individual passages 37. The space delimited by the intermediate plate 36, the side walls 34 and 35 and the upper sloping wall surfaces 31 and 32 is provided as a first flow space 42 for supplying the conditioning air L. A port 45 of the outlet member 57 to the flow channel 15 or 16 is shown schematically.

The conditioned air L then flows from the flow space 42 through the passages 37 of the intermediate plate 36 into a second flow space 43 which is formed between the side walls 34 and 35, the intermediate plate 36 and the lower bottom wall 38. The intermediate plate 36 with the passages 37 serves as a pre-distributor or to equalize the air flows and the conditioning air L. From the second flow space 43, the conditioning air L emerges in the form of three partial flows Ll, L2 and L3. The first partial flow Ll passes through an inclined wall portion 39 through corresponding outlet openings 47 obliquely down from, the second air flow L2 through a horizontally extending bottom portion 40 through corresponding passages 47 vertically down and the third partial flow L3 through corresponding passages 47 in an inclined wall portion 41 obliquely downward and in a different solid angle range than the first partial flow Ll off. This results in a very uniform, a large solid angle area detecting total air flow of the conditioning air L and substantially all tobacco T in the receiving space 20 or the receiving space 20 is detected by the conditioning air L and can be conditioned in terms of its temperature and / or humidity.

The outlet elements 51 to 57 or 51 'to 57' have the cross section according to FIG. 6 over almost their entire length, so that outlet openings 47 are provided distributed over their entire length and conditioning air L in the three partial flows L1 to L3 is substantially over the entire width of the receiving space 20 can flow out and thus conditioned the tobacco located in the receiving space 20 over a large area.

FIGS. 7 to 9 show a mixing and storage device for tobacco. In contrast to the embodiments of a pure memory device according to FIGS. 1 to 5, a feeding device 8 designed as a mixing carriage is now provided, which preferably comprises a conveyor belt or a belt conveyor. The feeder 8 supplies tobacco, which then falls down into the receiving space 20 of the storage device 2, and preferably has substantially the same width as the receiving space 20, so that the tobacco T similar to a waterfall over the entire width in the receiving space 20 falls. The feed device 8 is in the longitudinal direction of the receiving space 20, which corresponds to the conveying direction of the conveyor 4 at the bottom of the receiving space 20, in one

Mixing direction M movable back and forth, whereby the tobacco can be sprinkled or distributed over the entire length and width of the receiving space. The mixing and storage device shown in FIG 7 to 9 without the conditioning device 5 "is likewise known per se from the prior art and is referred to as a mixing and storage box or blending and storage silo.

With such a mixing and storage device, as shown in FIGS 7 to 9, the tobacco T is now dropped by the conditioning device 5 "arranged between the feed device 8 and the receiving space 20. In this falling movement, a part of the tobacco T also strikes the top side the outlet elements 51 "to 57", which consequently influence the fall and the distribution of the tobacco T. For these reasons, in this embodiment of a mixing and storage device, the design and arrangement of the conditioning device 5 "also with regard to the desired distribution of the tobacco T and the desired influence of this distribution by the conditioning 5 "self-adapted.

While it is, of course, advantageous that passages are provided in the conditioning device 5 "over the entire length so that the tobacco T can fall through at all, the formation of these passages as well as the formation of the remaining parts of the conditioning device 5" are also possible. to optimize. For example, the embodiments of the conditioning device 5 or 5 "already shown in FIGS. 2 and 4 are advantageous, in which only narrow outlet elements 51 to 57 or 51 'to 57' or 51" to 57 "are provided and wide passage spaces through them The distance a of the outlet elements is therefore essential, for example at least five times, larger than the dimension or width of the outlet elements themselves in the conveying direction F or mixing direction M. As a result, large passage spaces are formed for the falling through of tobacco T and it is still a sufficient values for the width of the outlet elements are 5 cm to 40 cm and for the distance a between the outlet elements 25 cm to 250 cm. The outlet elements 51 "to 57" likewise preferably have the cross-sectional shape according to FIG. 6, which is particularly advantageous for the tobacco which passes through or passes through as well as the impacting tobacco and also for the flow guidance of the conditioning air L. The design of the outlet elements 51 to 57 or 51 'to 57' or 51 "to 57" causes the tobacco to be deflected to the left and to the right of the outlet elements and to fall down so that a wave-shaped surface or topology with valleys and mountains results in the receiving space 20, the valleys being located directly under the outlet elements 51 to 57 or 51 'to 57' and 51 "to 57", respectively, which partially shield these areas like a roof. As a result, at the outlet end region 2B of the storage device 2 during transport through the conveyor 4 in the conveying direction F, the height of the tobacco filling in the receiving space 20 changes in a wave-like manner.

However, it can also, as shown in FIG 8, by an oblique arrangement of the mutually parallel web-like outlet elements 51 "to 57", for example, at an angle ß in a rectilinear training over the width of the receiving space 20 at the outlet end portion 2B is a different Height, since the valleys and mountains then run diagonally. As a result, segregation of the tobacco T can be prevented or reduced. The angle β is selected as a function of the distance and the length of the outlet elements and can in particular be selected between 10 ° and 60 °. Here, too, a large distance a between the outlet elements 51 "to 57" is preferably selected, which is significantly larger than their dimension in the conveying direction F or mixing direction M, in order to form large passages for the downwardly falling tobacco T.

10 now shows an embodiment of a device for conditioning the receiving space 20 or the tobacco T for a mixing and / or storage device 2 for tobacco T with a conditioning unit 7 shown in further detail in a circuit diagram. The conditioning unit 7 comprises a motor-controlled air flap 70 for controlling the flow cross-section and / or opening or blocking an inlet for outside air AU, which is taken from the atmosphere outside the production, a s flow technically behind filter 71 for filtering the outside air AU, a subsequent fan 72 for sucking the ambient air AU through the filter 71, a fan 72 downstream air cooler 73 for cooling down the air and / or condensation of moisture, a downstream air heater 74, for example, a heat exchanger with a secondary circuit with liquid as ^' heat medium, and a downstream humidifier 75. The output of the humidifier 75 is via the supply line 6 with the conditioning 5 and 5' Thus, the conditioning air L with a defined air temperature and air humidity is fed via the supply line 6 to the conditioning device 5 or 5 'or 5 "and thus to the tobacco T or the receiving space 20 of the mixing and / or storage device 2. Furthermore, a further motor-controlled air flap 76 is provided in the Konditionieraggregat 7, can be sucked through the Umluft UM from the factory or factory, in particular through the filter 71, preferably from an area above the storage device 2, in particular to save energy. It is now outside air AU and / or circulating air UM can be used to generate the conditioning air L.

In the exemplary embodiment according to FIG. 11, such a conditioning unit 7 is supplied in parallel with several, in FIG. 11 three, conditioning devices 5A, 5B and 5C, each of which has an associated receiving space 2OA, 20B and 2OC of a mixing and / or Storage device 2 for tobacco T is assigned. The three receiving chambers 20A to 20C are bordered by common housing walls 21 and arranged one above the other and rest on a common support frame 22 on the floor 10. The supply line 6 from the conditioning unit 7 is split or branched into two parallel feed strands 6A and 6B, the conditioning air parallel to each other Supply L to the conditioning devices 5A, 5B and 5C via associated motor-controlled louvers or other closing devices such as valves. Thus, between the feed line 6A and the conditioning device 5A, the air flap IA, between the feed line 6A and the conditioning device 5B, the air flap 12A and between the feed line 6A and the conditioning device 5C the air flap 13A. Similarly, between the Zuführstrang 6B and the conditioner 5A, the louver I IB, between the Zuführstrang 6B and the conditioning device 5B, the louver 12B and between the Zuführstrang 6B and the conditioning device 5C, the louver 13B. As a result, the individual conditioning devices 5A to 5C can be supplied individually with conditioning air L from one or both or none of the feed strands 6A and 6B, and control or regulation of the respective air volume (volume flow) is also possible. A similar arrangement could also be realized in the individual outlet elements 51 to 57 and 51 'to 57' and 51 "to 57" according to FIG 2, 4 or 8, to apply these individually with conditioning air L.

In all embodiments, the conditioning can be carried out by pure control (open control circuit) without measuring the conditioning variables solely on the basis of empirical pre-determined measurement data and empirical values, so that at least one conditioning quantity of the supplied conditioning air L is fixed.

However, it is preferred to regulate the conditioning variable (s) in a closed control loop by measuring the or each conditioning variable as a control variable and comparing the measured actual values with predefined setpoints and then, in the event of an impermissible deviation or control tolerance, conditioning air and its conditioning quantity (n ) are controlled as manipulated variables.

In particular, the tobacco temperature of the tobacco T can be measured contactlessly by a heat radiation sensor or infrared sensor, which can be arranged in particular on the feed device 3 or 8 (cf., for example, 27 in FIG. 7), and the air temperature of the conditioning air L above the receiving space 20 or above the tobacco T in the receiving space 20 by means of a temperature sensor or an arrangement of temperature 5), which may be fastened to the wall 21 in particular, are measured and the air humidity of the conditioning air L is measured analogously with a humidity sensor (eg 26 in FIG. 5) or an arrangement of humidity sensors. wherein by measuring the humidity of the air flowing on the tobacco T conditioning air L also indirectly the tobacco moisture is or may be determined, in particular empirically or mathematically. In addition, a measurement of the air temperature and / or humidity at a different location, in particular above the feeder 3 or 8, for example at a distance of 10 cm to 2 m, carried out to eliminate disturbances or compensate.

In a further embodiment, the fill level of the tobacco T in the receiving space 20 or its volume can be used as an additional parameter for the control of the air volume or the air volume flow or the air blow-off speed of the conditioning air L in order to charge a larger amount of tobacco T with sufficient conditioning air L. flow or even to achieve a more distant tobacco T with lower level still with the conditioning air flow L. To determine the fill level, the mass or the weight of the tobacco T can be determined indirectly by weighing.

In all embodiments, the flow velocity or blow-out speed of the conditioning air L at the outlet from the conditioning device 5 or 5 'or 5 "or in the air flow to the tobacco T or receiving space 20 out, especially at the exit from the outlet elements 51 to 57 and 51' to 57 'or 51 "to 57" or set from the outlet openings 47 on the underside thereof according to FIG. 6, preferably in a range between 0.2 m / s and 10 m / s.

The conditioning device 5 or 5 'or 5 "or at least their outlet elements 51 to 57 or 51' to 57 'or 51" to 57 "can also be in an embodiment, not shown, by at least one rotary be pivoted joint or pivot bearing. This makes it possible to pivot the air flow of the conditioning air L and / or their partial flows Ll to L3 in a solid angle range and to flow a correspondingly larger area with conditioning air L.

Instead of conditioning air L, a different gas or gas mixture can be used in all embodiments. In particular, the gas composition can then be controlled or regulated as a conditioning quantity, for example a protective gas such as nitrogen or a nitrogen-rich gas atmosphere could be used at least temporarily to eliminate the oxidizing effect of oxygen.

The invention is not limited to the conditioning of tobacco. Rather, other products in a receiving space of a mixing and / or storage device in industrial production such as food and / or bulk materials can be conditioned with the measures according to the invention.
