Description

The invention relates to a device for the recovery of smoking article waste, the wrapping material strip flags from, in particular paper having, wrapping material and fiber material strands of, in particular filter tow or tobacco material exhibiting, fiber material and loose, in particular filter tow or tobacco material containing fiber material particles.

The term "smoking article waste" in the context of the present invention is understood to mean waste produced in the manufacture of smoking articles. For the purposes of the present invention, this includes wrapping material strip flags, in particular paper-containing wrapping material and thus in particular wrapping paper in strip form. Furthermore, this includes loose, in particular filter tow material or tobacco material having, tobacco material particles, which are thus in particular filter filament material and filter fiber material or cut tobacco and tobacco fibers. For smoking article waste, the term "shot" is alternatively used. In the case of rope-shaped smoking article waste, this is also referred to as "continuous shot", which is the fiber material of the fiber material strands mentioned at the outset, in particular filter tow material or tobacco material. Since the start of the plant is often initially produced transitional only with a lesser quality and / or in this transition state, the strand is still open, one speaks in such cases also of "starting shot". Since the shutdown of the system often continues to produce with decreasing quality, one speaks in such a case of "stop shot".

For the purposes of the present invention, "smoking articles" are understood to mean all types of smoking articles, in particular cigarettes, filter cigarettes, cigarillos and cigars, regardless of whether they are already finished or are still in a certain production stage, and furthermore whether they are a rod shape with discrete length or in the form of an infinite strand.

Not least for reasons of cost, there is a high interest in supplying at least a major part of the smoking article waste to a further utilization and thus returning it back into production. Because the "shot" contains valuable substances or materials as components such. As filter material, filter caps with tipping, tobacco, wrapping paper for tobacco, etc. Therefore, this suitable device is used, which separate and process the smoking article waste accordingly.

In the EP 0 634 259 A1 discloses an apparatus for recovering individual components from smoking article wastes. This known device has as Aufschlusseinrichtung a mill, the rod-shaped smoking article decomposed into their individual components. The mill includes a stator having one or more stationary jaws and a rotor having a plurality of radial jaws, wherein the stationary jaws and the radial jaws are radially spaced from each other when confronting each other. The mill is adapted to receive as a waste material from the filter cigarette production so-called cigarette scrap, which contains as components tobacco, the paper material enveloping the tobacco and filter plug as filter material with tipping. This waste material is fed to the mill as sliced scrap cigarettes. Furthermore, the known device has a conveyor, which is designed as a vibrating conveyor with two screens and receives at a receiving portion of the output from the mill components and further transported in a conveying direction. Furthermore, the known device comprises a suction device, which is adapted to receive paper material from filter plugs from the conveyor at a location downstream of the receiving portion by means of suction and to convey into a suction line. On the other hand, filter plugs with tipping remain on the upper wire of the conveyor, while residual paper and fine tobacco fall through the upper wire on the lower wire catching the waste paper and dropping the fine tobacco on an underlying bottomed groove.

It is an object of the present invention to provide a device of the type mentioned, which allows a separation of the individual components from the smoking article waste in an effective and structurally simple way.

Furthermore, according to the invention, an injector operated with compressed air and acting in the suction line is provided, which generates the desired suction effect in the suction device in a particularly effective manner.

Preferred embodiments and further developments of the device according to the first aspect of the invention are specified in the dependent claims 2 to 16.

Thus, the conveyor is preferably designed as a vibratory conveyor, which can be realized in a structurally simple and effective manner, a transport of the components obtained by the shredder. To be able to use the conveyor as a separating device at the same time, the vibratory conveyor preferably consists of a gutter having a closed bottom and a single sieve arranged above the gutter, which is designed to receive the pieces of fiber material dispensed by the shredder, pieces of fiber material and fiber material, and essentially only the Pass fiber material particles towards the gutter.

Preferably, further, a switch is used, which allows the option, even before entering the shredder seized Umhüllungsmaterialfahnen over the first inlet to receive and output in particular for transport into a collection container via the outlet. On the other hand, the second inlet is connected to the suction duct, over which wrapping material pieces picked up by the suction device are transported, so that the switch further offers the option of alternatively guiding the wrapping material pieces to the outlet via the second inlet.

It has been found that the operation of the injector is particularly high when it is connected adjacent to the second inlet of the switch to the suction line or directly to the second inlet of the switch.

Preferably, a sorting device is provided, which is designed to weed Umhüllungsmaterialfahnen before an eventual entry into the shredder from the smoking article waste, thus record independently of the shredder and to transport to the first inlet of the switch. The use of such a sorting device is particularly advantageous when wrapping material flags are to be deducted with a significantly greater length and in particular over a longer period. In addition, the chopper is spared in this way.

Conveniently, a wrapping material receptacle is provided for receiving recovered wrapping material. When using the aforementioned switch, the wrapping material receptacle is connected at the outlet of the switch to collect the wrapping material lugs conveyed via the first inlet of the switch and collects together the wrapping material pieces conveyed via the second inlet of the switch.

Further, a cabinet may conveniently be provided having an upper portion in which a wrapping material receptacle for receiving recovered wrapping material is disposed, and an upper end terminating upper portion in which an inlet facing or leading to the wrapping material receptacle is formed Use of the aforementioned switch is preferably connected to the outlet. Characterized in that the inlet is arranged substantially in a vertical position, the filling of the arranged in the upper portion of the cabinet wrapping material receiving container is favored due to the force of gravity. For this reason, it is advantageous to form the wrapping material receptacle open at the top. For ease of emptying and easy cleaning, preferably the wrapping material receptacle should be removably mounted in the cabinet.

Preferably, the cabinet and / or the wrapping material receiving container to venting in order to achieve a good air permeability and thus allow the excess pressure resulting from the pneumatic conveying escape back to the outside. Advantageously, the venting means are provided with filter means.

Furthermore, the object is achieved according to a second aspect of the invention with a device for the recovery of smoking article waste comprising Umhüllungsmaterialfahnen from, in particular paper having, wrapping material and fiber strands of, in particular filter tow or tobacco material having, fiber material and loose, in particular filter tow or tobacco material containing fiber material particles , in particular according to at least one of the preceding claims, with

• A shredder adapted to cut the wrapping material lugs into wrapping material pieces and the fiber material strands into fiber material strand pieces and / or fibrous material particles, wherein
• The shredder has a chamber substantially delimited by a circumferential wall, with an inlet and an outlet, a chopper rotor rotatably mounted in the chamber, and at least one first knife arranged in the chamber in a tationary manner,
• The chopper rotor has at least two radial rotor blades, at the free end of which a second knife interacting with the at least one first blade is arranged,
• - Between each two adjacent radial rotor blades and the wall of the chamber, a receiving space for receiving fiber material particles is formed, and
• - The knives are formed substantially only for cutting the wrapping material flags and the fiber material strands.

While at the mill according to the EP 0 634 259 B1 the radial jaws are passed at a distance from the stationary jaws and thus a gap between the radial jaws and the stationary jaws remains, the shredder according to the invention is used as a cutting device, wherein the attached at the free ends of the radial rotor blades second knife during the movement of the chopper rotor past the stationary first knife with this to achieve a cutting action into engagement. Due to the special geometry of the radial rotor blades provided on the chopper rotor, a receiving space is formed according to the invention between each two adjacent radial rotor blades and the wall delimiting the chamber, which receives the fiber material particles and further transported due to the rotation of the chopper rotor by the radial rotor blades, also referred to as paddles can act in the manner of a blade and thus take the fiber material particles with rotation of the chopper rotor. Because the fiber material particles do not need to be cut and therefore need not be passed between the knives. This ensures that the knives only have to cut the wrapping material lugs and the fiber material strands. This leads to less stress on the blades and thus less wear, so that the risk of erupting blades is avoided. Therefore, the shredder can also be referred to as a strand chopper.

Preferred embodiments and further developments of the chopper are specified in the dependent claims 18 to 24.

Thus, the wall bounding the chamber preferably has an upper portion in which an inlet is formed, and a lower portion in which an outlet is formed. In this way, the transport of the smoking article waste by the shredder is not only caused by the rotation of the chopper rotor, but also supported by gravity. The chamber thus forms a kind of shaft in which the smoking article waste are moved down.

Preferably, the axis of rotation of the chopper rotor is aligned substantially horizontally during operation.

In a further preferred embodiment, the radial rotor blades each contain at least one opening which is designed such that, in particular by the influence of gravity, the fiber material particles simply move through the openings of the rotor blades and thus through the chamber and fall down, but the rotor blades nevertheless being able to generate such an air flow due to their rotation that thereby blows the wrapping material lugs and fiber strands toward the stationary first knife and thus deflects and guides to the first knife to cut accordingly between the first and second knives become. The chopper expediently has a drive motor with a motor rotor which rotatably drives the chopper rotor.

In order to ensure optimum controllability of the drive motor, the moment of inertia of the motor rotor should preferably be at most one fifth of the moment of inertia of the chopper rotor and thus the ratio of the moments of inertia from motor rotor to chopper rotor not be greater than 1: 5.

Furthermore, the chopper preferably has a housing in which the chamber is formed, wherein the drive motor is arranged on an outer side of the housing and the coupling between chopper rotor and motor rotor is designed separable. Accordingly, in this embodiment, the chopper is constructed so that the cutting part with the chopper rotor can be easily separated from the drive part with the drive motor during disassembly. The coupling between chopper rotor and motor rotor takes place by a torsionally rigid coupling, which can be solved for disassembly. In particular, the cutting part should be separated from the drive part, so that the drive part remains in the device. The cutting part can then be taken out of the device for maintenance and service.

Preferably, a control device is provided, which is designed to control the drive motor in dependence on the strand speed of Umhüllungsmaterialfahnen and / or the fiber material strands such that the peripheral speed of the free ends of the rotor blades at least substantially corresponds to the strand speed. By thus controlled drive can thus adjust the speed of the rotating second knife of the respective strand speed, whereby an optimal cutting of the Umhüllungsmaterialfahnen and / or the fiber material strands is possible. In this context, it should be noted that the shredder, which is indeed part of an entire plant for the production of smoking articles, usually only for the preparation of starting shot or stop shot at start or stop the plant is used.

Furthermore, the aforementioned object according to a third aspect of the present invention is achieved with a device for the recovery of smoking article waste, the wrapping material flags from, in particular paper exhibiting, wrapping material and fiber strands of, in particular filter tow or tobacco material containing, fiber material and loose, in particular filter tow or tobacco material comprising fiber material particles, in particular according to at least one of the preceding claims, with

• A shredder, which is designed to cut the wrapping material lugs into wrapping material pieces and the fiber material strands into fiber material strand pieces or fiber material particles,

• - Wherein within the suction hood an adjustable, preferably pivotally mounted, air control flap is arranged such that can be adjusted by adjusting the air control flap of the suction angle relative to the conveyor and / or the suction cross-section.

Accordingly, an adjustable flap is provided according to the invention within the physical limits of the suction hood, with the structurally simple, but effective way, the speed of the suction air flow and thus the conveying speed of the recorded Umhüllungsmaterialstücke can influence within the suction. This is inventively achieved in that can be adjusted in the region of its opening using the air control flap according to the invention, the suction cross section of the suction hood. In particular, when the air control flap is pivotally mounted, results as a further advantageous effect, the adjustment of the suction angle relative to the conveyor.

The suction effect in the suction device according to the invention is generated by the injector, which thus also determines the suction power. It has been found according to the invention that the effect of the injector is particularly high when the injector is located at the end of the suction line remote from the suction hood and there acts in the suction line.

Preferred embodiments and developments of the suction device are specified in the dependent claims 26 to 29.

Thus, it is advantageous if the opening of the suction hood extends substantially over the entire width of the conveyor. This ensures namely that the wrapping material pieces in their entirety can be taken up by the conveyor.

Preferably, the suction hood has the shape of a curved or curved funnel whose tapered end portion is provided with a curved portion. For this purpose, it has been found according to the invention that, in the case of a lateral arrangement of the outlet, to which the suction line is to be connected, the curved section for a Homogenization of the suction effect over the entire width of the suction hood ensures.

In a further preferred embodiment, the suction hood is pivotable about a pivot axis, which runs substantially parallel to a conveyor plane spanned by the conveyor. By means of such a pivotable arrangement, the distance to the conveyor can be adjusted in a simple manner, which is important for the extraction of the wrapping material pieces. In particular, for spatial considerations, it is advantageous if the suction hood has an outlet through which the pivot axis passes.

Furthermore, the aforementioned object is achieved according to a fourth aspect of the present invention with a device for the recovery of smoking article waste, the wrapping material flags from, in particular paper having, wrapping material and fiber strands of, in particular filter tow or tobacco material having, fiber material and loose, in particular filter tow or tobacco material having , Fiber material particles comprise, in particular according to at least one of the preceding claims, with

• A shredder, which is designed to cut the wrapping material lugs into wrapping material pieces and the fiber material strands into fiber material strand pieces or fiber material particles,
• A conveyor which is designed to receive at a receiving section the wrapping material pieces, fiber material extrudates and fiber material particles delivered by the shredder and to transport them further in a conveying direction,
• - A suction device which is adapted to absorb substantially only the wrapping material pieces from the conveyor at a position downstream of the receiving portion by means of suction and to promote in a suction, and
• - A switch with a first inlet, which is adapted to receive even before entering the shredder separated Umhungsungsfahnen, a second inlet, which is connected to the suction line, and an outlet, wherein
• - The switch includes closing means which selectively close the first inlet or the second inlet, so that only one of the two inlets is always open and connected to the outlet.

The pneumatic switch is used to lead two materials to be conveyed, which are on the one hand to previously rejected wrapping material flags and on the other hand to cut wrapping pieces of material, from different directions individually to a common outlet.

The use of closing means ensures that the switch only unlocks the path in which the wrapping material is to be conveyed. So if previously rejected wrapping material flags are promoted, the path between the first inlet and the outlet is released. If, on the other hand, the wrapping material pieces picked up by the suction device and previously cut by the shredder are to be transported further, the switch shifts the path between the second inlet and the outlet. In each case, the other of the inlets remains closed. In this way, the emergence of an undesirable bypass by the other unused conveyor is avoided.

Preferred embodiments and developments of the switch are given in the dependent claims 31 to 34.

From the above considerations, that the injector operated by compressed air works most effectively when placed at the distal end of the suction line, it is constructive and at the same time advantageous in terms of its effect to connect the injector to the second inlet or to integrate it into the second inlet of the switch. In addition, this design also has spatial advantages. For a particularly effective supply of compressed air, the second inlet should preferably be provided with an annular gap to which the injector is connected, so that the pneumatic compressed air via the annular gap ensures the production of the conveying speed. To set the conveying speed, it is preferable to provide a throttle valve which is connected to the injector and designed to control the compressed air in terms of speed and pressure in the injector.

Finally, preferably within the switch, the paths leading from the inlets to the outlet should be substantially smooth-walled and thus substantially free of interference edges, after which the paths are essentially delimited by smooth walls in order to prevent blocking of the wrapping material to be conveyed.

Hereinafter, preferred embodiments of the invention will be explained in more detail with reference to the accompanying drawings. Show it:

For the production of cigarettes, an endless strand is preferably first formed, which consists of tobacco and is wrapped with paper and glued. From this strand bars of finite length are cut according to the desired cigarette length. For the formation of the strand shape, a format or a format device is provided. For this purpose, the tobacco in loose strip form, which otherwise has no defined shape, transported into the inlet of the format and formed within the format to a solid strand with a round cross-section. Usually, the format has an endless circulating format tape which enters the inlet of the format and exits the format outlet and is deflected back outside the format to the inlet. Usually, before entering the format between tobacco and format tape, a strip of paper is laid which forms the subsequent wrapping paper which wraps the tobacco within the format. Thus, in this case, the format tape still has the additional task of laying the paper strip around the tobacco during the formation of the strand within the format.

When starting up and shutting down a cigarette manufacturing machine falls just in the field of format and in particular at its outlet a relatively high amount of loose tobacco fibers and loose paper flags and already an endless strand or at least strand sections, all collectively referred to as "shot". Since the start of the plant is often initially produced transitional only with a lesser quality and / or in this transition state, the strand is still open, the shot is referred to in such cases as "approach shot". Since the shutdown of the system often continues to produce with decreasing quality, one speaks in such a case of "stop shot". The entire starting shot, which consists of loose tobacco fibers, paper flags and a strand or strand sections, as well as the entire stop shot, which consists essentially of a strand, are then promoted by means of the mentioned format tape in the direction of a Strandabschlägers, not shown.

It is therefore necessary to separate and recover the shot and in particular the starting shot from the production path of the cigarette manufacturing machine and thereby to separate the paper from the tobacco. For this purpose, the in 1 shown arrangement provided.

In 1 the shot is schematic by three arrows 2 . 4 and 6 indicated, the arrow 2 loose tobacco fibers, the arrow 4 Paper banners and the arrow 6 represents a strand. This shot first reaches a shredder 10 whose structure and functioning are based on the 2 to 4 results. As these figures show, the chopper points 10 a housing 12 on whose interior is a chamber 14 forms. The chamber 14 is from an end wall 15 and, sidewalls 16 of the housing 12 and a rear wall forming, plate-shaped flange 18 limited. At the top of the case 12 , which preferably consists of a one-piece cast body, is an inlet opening 20 formed on one side by an obliquely arranged guide plate 22 is limited. The in 1 using the arrows 2 . 4 . 6 Schematically shown shot passes over the guide plate 22 and the inlet opening 20 in the chamber 14 of the shredder 10 , At the bottom of the case 12 is an outlet opening 24 provided by the shot the chopper 10 leaves again. Thus, the chamber forms 14 a kind of shaft in which the shot is moved down.

Inside the chamber 14 is a stationary, strip-shaped first knife 26 disposed by placing it on a rod-shaped knife holder 28 screwed, in turn, on the housing 12 is fixedly mounted. Furthermore, inside the chamber 14 a shredder rotor 30 around a rotation axis 32 rotating arranged at the front 15 of the housing 12 stored and in the installed state of the chopper 10 is oriented substantially horizontally, in particular the 2 and 3 reveal. The chopper rotor 30 has several rotor blades 34 on, which can alternatively be referred to as a paddle and are arranged generally equidistantly from each other. In the illustrated embodiment, three rotor blades 34 provided, which are each arranged at an angular distance of 120 ° to each other. How the particular 3 and 4 further can be seen, are the rotor blades 34 with a central rotor body of the chopper rotor 30 screwed and can thus easily replace. The free ends of the rotor blades 34 each carry a strip-shaped second knife 36 , The three second knives used in the present embodiment 36 Although essentially run in the direction of the axis of rotation 32 but are slightly inclined relative to this, while the strip-shaped first knife 26 essentially parallel to the axis of rotation 32 is aligned. In particular 3 furthermore, the second knives are 36 , which may also be referred to as rotating blades, on the free ends of the radial rotor blades 34 screwed. The geometry and arrangement of the rotor blades 34 and the first and second knives 26 . 36 are so taken that upon rotation of the rotor 30 the second knives 36 each temporarily in touching engagement with the first knife 26 arrive, whereby a cutting process is triggered.

Due to the arrangement and geometry of the rotor blades 34 is between each two adjacent rotor blades 34 and the chamber 14 limiting side walls 16 a reception room formed in 4 outlined by dashed lines and with the reference numeral " 38 "Is designated. This recording room 38 takes the (in 1 with the arrow 2 schematically marked) loose tobacco and transported due to the rotation of the chopper rotor 30 the loose tobacco from the inlet opening 20 to the outlet opening 24 by removing the radial rotor blades 34 act like a shovel and through the inlet opening 20 incoming loose tobacco upon rotation of the chopper rotor 30 take along accordingly. Because the loose tobacco does not need to be cut and therefore does not have to be between the knives 26 . 36 to be passed through. Rather, the knives must 26 . 36 only the (in 1 schematically by the arrow 4 indicated) paper flags and the (in 1 schematically by the arrow 6 indicated) cut strand. This leads to a lower load on the blades 26 . 36 and thus less wear, so that the risk of erupting knives is avoided.

In particular 4 is the stationary first knife 26 inside the chamber 14 immediately next to the inlet opening 20 arranged and move the rotating second knife 36 over the entire inlet opening 20 along. This has the consequence that the paper flags and the strand immediately after their entry through the inlet opening 20 from one of the radial rotor blades 34 fully grasped and towards the fixed first knife 26 get picked up. The short path due to the inlet opening ensures 20 adjacent arrangement of the fixed first knife 26 for a substantially smooth and immediate cut.

By appropriate choice of the number of rotor blades 34 and the rotor speed of the chopper rotor 30 The number of cuts per given length of the paper flags and the strand and thus also the length of the cut material can be determined. Not least because of the screwed attachment, it is also possible to use knives of a different shape and orientation. For example, it is conceivable, alternatively to the representation in the 3 and 4 the second knives 36 not in approximately tangential orientation, but, for example, in a substantially radial orientation on the rotor blades 34 to arrange.

Like the others 3 and 4 can be seen in the illustrated embodiment in the radial rotor blades 34 one opening each 40 included, which ensures that the loose tobacco is also influenced by gravity through the openings 40 in the radial rotor blades 34 move and thus essentially also directly through the chamber 14 down towards the outlet 24 can fall. These are these openings 40 so measured that by the rotation of the chopper rotor 30 due to the "fan" effect of the rotor blades 34 an air flow is created which is capable of (in 1 schematically by the arrow 4 indicated) paper flags and the (in 1 schematically by the arrow 6 indicated) strand towards the stationary first knife 26 to blow, then this between the first and second knives 26 . 36 get cut.

If the shot to be processed contains loose filter tow alternatively or in addition to the loose tobacco, then what has been said previously for loose tobacco applies in the same way to the loose filter tow.

As the 2 and 3 Furthermore, it is on the outside of the flange 18 outside the case 12 a drive motor 42 mounted, whose unrecognizable rotor the chopper rotor 30 rotating drives. For optimum controllability of the drive motor 42 to ensure, the moment of inertia of the motor rotor should preferably a maximum of one fifth of the moment of inertia of the chopper rotor 30 be. The coupling between chopper rotor 30 and motor rotor is made by a likewise not recognizable torsionally rigid coupling, which, however, can be solved for disassembly.

The flange is preferred 18 mounted at a suitable location within the device and is the housing 12 detachable on the flange 18 attached. Because the case 12 as a carrier for the knife holder 28 with the first knife fixed 26 and the chopper rotor 30 is used, these components together form a so-called cutting part, which is thus from the drive motor 42 disconnect, which remains in the device. This makes it possible to remove the cutting part for maintenance and service individually from the device.

Furthermore, a control device not shown in the figures is provided, which is formed, the drive motor 42 as a function of the strand speed of the paper flags and / or the strand to regulate such that the peripheral speed of the second knife 36 at the free ends of the rotor blades 34 at least substantially equal to the strand speed. By thus controlled drive can thus be the speed of the chopper rotor 30 adjust accordingly, whereby an optimal cutting of paper flags and / or strands is possible. In this context it should be noted that the shredder 10 , which is part of an entire plant for the production of filter cigarettes, is usually used only when starting or stopping the plant.

That from the shredder 10 weft material processed according to the preceding description, now from the shredder 10 sliced pieces of paper and skeins, and further comprising the loose tobacco, passes through the outlet 24 of the shredder 10 spent down, as in 1 through the arrow 44 is indicated. In the illustrated embodiment, the weft material falls on a conveyor 50 In detail, in the 5 and 6 is shown. The conveyor 50 is formed in the illustrated embodiment as a vibratory conveyor such that the goods to be transported due to vibrations of an upstream first section 50a to a downstream second section 50b is transported. As 5 is the chopper 10 above the upstream first section 50a of the conveyor 50 arranged so that its outlet 24 on this section of the conveyor 50 is directed. As a result, in the direction of in 1 shown arrow 44 the weft material from the shredder 10 in the conveyor 50 falls while being from its upstream first section 50a is recorded.

As 6 In detail, the conveyor points 50 a gutter 52 with a closed floor. The gutter 52 is on four leaf springs 54 stored, which serve as supports, over which the gutter 52 is supported on a substrate, not shown. As the 5 and 6 can also be seen, are the leaf springs 54 inclined relative to the vertical, wherein the angle of attack relative to the vertical is preferably about 25 °. To generate the vibrations is below the gutter 52 an engine 56 arranged. The vibrations are by an unillustrated connecting rod via an eccentric, also not shown in the trough 52 initiated, leaving the gutter 52 due to the described arrangement of the leaf springs 54 in from the first section 50a to the second section 50b of the conveyor 50 oriented conveying direction oscillates reciprocally. The acceleration of the gutter 52 depends on the drive speed of the motor 56 and the size of the eccentric.

To the conveyor 50 at the same time to use as a separator, is above the gutter 52 a single sieve 58 arranged. Thus, that comes from the shredder 10 discharged and from this falling shot material in the upstream first section 50a of the conveyor 50 first completely on this sieve 58 , The sieve 58 is intended as a kind of intermediate floor and designed so that of the shredder 10 discharged shot material essentially only the loose tobacco through the sieve 58 on the gutter underneath 52 falls while the pieces of paper and the strand pieces on the wire 58 remain. Preference is given to the holes of the sieve 58 as in the conveying direction and thus in the direction of the longitudinal extent of the conveyor 50 formed elongated holes. Of course, due to the vibrations described above, not only is the loose tobacco along the gutter 52 , but also the pieces of paper and strand pieces along the extent also acting as a false bottom sieve 58 towards the downstream second section 50b of the conveyor 50 emotional. The size of the holes of the sieve 58 is chosen in dependence on the weft material to be conveyed such that a retention of the pieces of paper and strand pieces on the wire 58 while moving along the conveyor 50 remains guaranteed.

As 1 combined with 5 recognize is a suction device 60 with a suction hood 62 provided over the conveyor 50 in the region of its downstream second section 50b arranged and in detail in the 7 and 8th is shown. The extraction hood 62 has turned the basic form of one arranged funnel, whose wide intake opening 62a directly above the screen 58 in the region of the downstream second section 50b of the conveyor 50 lies.

Although possesses the exhaust hood 62 the basic form of a funnel, however, is its upper section 62b formed curved or curved. That's why the entire shape of the extractor hood 62 also be referred to as a curved funnel. In particular 5 can recognize, the suction extends 62a the extraction hood 62 over the entire width of the conveyor 50 , resulting in a substantially uniform flow distribution over the entire width of the conveyor 50 is reached. Laterally on the upper section 62b the extraction hood 62 is a tubular outlet 64 provided to the a suction line 66 connected.

As 8th is within the extractor hood 62 about a joint 68 an air regulating flap 70 Hanging away from the one in the area of the upper section 62 the extraction hood 62 arranged joint 68 into the suction opening 62a extends. In the illustrated embodiment according to 8th is the pivot axis 69 of the joint 68 essentially horizontally and transversely to the conveying direction of the conveyor 50 oriented so that the air control flap 70 in the conveying direction of the conveyor 50 is pivotable. This can be achieved using the air control flap 70 the effective opening cross section of the suction opening 62a and thus the suction cross section of the suction hood 62 in the area of their suction opening 62a depending on the pivoting position of the air regulating flap 70 to adjust. The change in the effective opening cross-section of the suction 62a is by changing the distance of the air control flap 70 with its lower free end from an opposite wall section 62c the extraction hood 62 certainly; is the distance between the air control flap 70 and said wall section 62c small, the suction cross-section is small, and is the distance between the air control flap 70 and said wall section 62c large, this results in a correspondingly large suction cross-section. Because the air control flap 70 in the conveying direction of the conveyor 50 is pivotable, the width of the suction remains 62a the extraction hood 62 unaffected. This has the advantage that regardless of the pivoting position of the air regulating flap 70 and thus the adjustment of the suction cross section, the suction effect over the entire width of the conveyor 50 always preserved. The adjustment of the air control flap 70 takes place by means of an actuator, not shown in the figures.

In the illustrated embodiment, the suction hood depends 62 at the outlet 64 , which is mounted within the device on a frame or scaffolding, not shown. For hanging attachment to the extraction nozzle 64 is the top section 62b the extraction hood 62 with a mounting flange 72 provided, the several corresponding curved or curved slots 74 having. The tubular outlet 64 is at his to the exhaust hood 62 adjacent end provided with a similar mounting flange, in the view of the figures from the mounting flange 72 the extraction hood 62 hidden and therefore not recognizable. The connection of the two mounting flanges is done by screws 76 passing through oblong holes 74 in the mounting flange 72 are stuck, like the 7 and 8th reveal. Because of the slots 74 can the suction hood 62 about one of the length of the slots 74 optionally fix certain angle range in different pivot positions, so far as the exhaust hood 62 around a pivot axis 78 which is pivotable within the tubular outlet 64 runs and preferably coincides with the central axis. Due to the swiveling adjustment of the extraction hood 62 can be easily the distance from the intake 62a to the promoter 50 and at the same time also the location of the extraction with respect to the conveyor 50 to adjust.

Incidentally, on the suction side of the suction hood 62 adjacent to the suction opening 62a at the wall section 62c an inlet sheet 62d Arranged towards the shredder 10 and thus against the conveying direction of the conveyor 50 extends in the upstream oriented direction, like the 7 and 8th combined with 5 reveal. The inlet sheet 62d has the shape of a partial arc, its axis of rotation approximately with the pivot axis 78 coincides. This is the inlet sheet 62d so to speak, at the pivot point of the extraction hood 62 adapted and thus favors the suction hood in each pivot position 62 the reception of the paper pieces, since the suction air at the entrance of the suction 62a can not tear off.

To ensure that from the exhaust hood 62 only the pieces of paper according to arrow 59 from 1 from the sieve 58 of the conveyor 50 be received, it requires the optimal adjustment of the conveying speed and the distance between the intake 62a the extraction hood 62 and the sieve 58 of the conveyor 50 , Since the conveying speed depends on the suction cross-section, the yes with the Luftregulierungsklappe 70 can be adjusted causes the air control flap 70 as a result, an adjustment of the conveying speed while the distance from the conveyor 50 due to the swiveling suspension of the extraction hood 62 can be set. Both parameters, ie the conveying speed within the extraction hood 62 and the distance of the extraction hood 62 from the conveyor 50 , are important for optimal extraction of paper pieces. It is also important for optimum suction of paper pieces, that the substrate on which the pieces of paper are transported, is designed to be permeable to air, what with the sieve 58 of the conveyor 50 the case is.

As 9 combined with 1 lets recognize, leads the suction line 66 from the suction device 60 to a switch 80 whose structure is in detail from the 10 and 11 results. The soft 80 has a first inlet 82 on, to the via a pneumatic conveying line 84 a pneumatic paper threader 86 connected. The in the 1 and 9 only schematically illustrated Papiereinfädler 86 is used in the present case as a sorting device and is designed paper flags before a possible entry into the chopper 10 Weed out the shot and therefore independent of the shredder 10 take. The paper threader 86 recorded paper flags are thus on the pneumatic conveying line 84 into the switch 80 through their first inlet 82 transported. Furthermore, the switch points 80 a second inlet 88 on, to the suction line 66 connected. The switch also has an outlet 90 to, within the switch 90 from the first inlet 82 a first path 83 and from the second inlet 88 a second path 89 leads, and contains a hinged flap 92 , as 11 lets recognize. Using the hinged flap 92 is only one of the two paths 83 . 89 unlocked and closed the other path. In this way, the emergence of an unwanted bypass by the other unused path is avoided. Thus, the switch offers 80 the option, either from the paper threader 86 pre-separated paper flags or those of the suction device 60 picked pieces of paper at the outlet 90 issue. Switching the switch 80 effecting adjustment of the flap 92 takes place in the illustrated embodiment via an outside of the switch 80 arranged pivot lever 94 from a pneumatic cylinder 96 is operated accordingly, as 10 lets recognize. Incidentally, the cavities are in the switch 80 formed by the two entrances 82 . 88 , the two paths 83 . 89 and the common outlet 90 , consistently provided with smooth walls and thus contain no edges, creases, projections and other unsteady places where the paper could get stuck, which incidentally also for the design of the flap 92 equally applies, as well as in 11 is shown schematically.

As 1 furthermore, is an injector 100 provided that the suction in the suction device 60 generated and thus determines the suction power. The effect of the injector 100 is then particularly high when he is at the of the suction hood 62 distant end of the suction line 66 is provided and there in the suction 66 acts as in 1 sketched is indicated. In the presentation of the 10 and 11 is the injector 100 in the second inlet 88 the switch 80 Integrates and feeds the compressed air through an annular gap 102 in the second inlet 88 one. But if the first path 83 unlocked, how 11 shows, the injector 100 ineffective, because the flap 92 the second inlet 88 and thus the second path 89 closes. The injector is supplied and controlled 100 via an external throttle valve 104 and a correspondingly connected pneumatic line 106 , as 10 lets recognize.

At the outlet 90 the switch 80 is another support line 110 connected to a paper container 112 leads, like 9 combined with 1 lets recognize. The paper container 112 serves to that of the suction device 60 sucked pieces of paper and the paper threader 86 Collect discarded paper flags.

As 1 further can be seen schematically, the on the screen 58 of the conveyor 50 remaining strand pieces that are in 1 through an arrow 114 are indicated, as well as on the gutter 52 of the conveyor 50 below its sieve 58 collected loose tobacco, which in 1 through an arrow 115 is indicated in common in a shot tank 120 is passed, in which thus the strand pieces and the loose tobacco are collected.

As 9 furthermore, is a cabinet 130 provided at its top 130a a tubular inlet nozzle 132 has, to those of the outlet 90 the switch 80 upcoming support line 110 connected. The cupboard 130 is divided into an upper section and a lower section. In the upper section of the cabinet 130 is the in 1 schematically illustrated paper container 112 housed, which is not recognizable in the figures however. The paper container 112 is open at the top and below the inlet nozzle 132 arranged. Because the inlet pipe 132 oriented substantially vertically and on the upwardly open paper container 112 is directed, the loading of the paper container 112 favored with the pieces of paper and / or flags due to the effect of gravity.

Accordingly, the cabinet serves 130 in the described embodiment for receiving the paper container 112 out 1 , The thus formed as an inner container container 112 is preferred in cabinet 130 removably arranged to simply remove it from the cabinet for emptying, replacement and / or cleaning 130 to be able to remove. To the resulting from the pneumatic conveying pressure from the inside of the cabinet 130 to escape to the outside, is the cabinet 130 provided with appropriate venting agents, which achieve a good air permeability. As an example of such deaerating agents are in 9 two vents 134 . 136 pictured in a sidewall of the cabinet 130 are formed and provided with filter means.

To make a simple change of location if necessary and in particular the cabinet 130 easy to remove from the rest of the device is the cabinet 130 at its bottom 130b with roles 138 provided that it is parked on a substrate, not shown.

If the shot to be processed contains loose filter tow alternatively or in addition to the loose tobacco, then what has been said previously for loose tobacco applies in the same way to the loose filter tow.
