Description
Attorney Docket: 31653-169823 Translation of German text IW/file # 265692 Method and Device for Preparing Fibrous Plant Material The invention relates to a method and a device for preparing fibrous plant material, in particular from hemp plants, for further processing. In addition, it relates to a new use for a tobacco cutter, known from the tobacco-processing industry.
It is the object of the invention to specify an additional method and an additional device of the aforementioned type, which make it possible to achieve a higher-yield and a more efficient preparation of the fibrous plant material for a later or a subsequent further processing.
This object is solved according to the invention for a method of the aforementioned type in that the fibrous plant material is campressed and is then cut into sections of a desired length. The preferred usable fiber components are then separated out from the flow of cut fibrous plant material, so that they can be processed separately.
The problem present herein is solved according to the invention for a device of the aforementioned type by using means for conveying the fibrous plant material in a conveying direction along a conveying path that moves through a compacting zone. It is further solved with compression means, arranged on both sides of the conveying path, for compressing the fibrous plant material conveyed through the compression zone, as well as a cutting device for cutting the compressed fibrous plant material into sections of a predetermined length. The invention also provides for a device for separating the fiber components from the wood and stem components of the cut fibrous plant material. The Attorney Docket: 31653-169823 WO 00/14312 PCT/EP99/065b7 object is further solved according to the invention in that a tobacco cutter, known in the tobacco industry for cutting tobacco, is used for compressing, breaking up and cutting of the fibrous plant material, in particularly from hemp plants.
Modifications, improvements and advantageous embodiments of the method and the device according to the invention are provided in the dependent claims.
A particular advantage of the invention is that it allows a more efficient preparation of the fibrous plant material for further processing. The method and device operate with a high material throughput and a high degree of efficiency. The uniform cutting of the compressed fibrous plant material, carried out with the tobacco cutter, already leads to a loosening of the fiber components in the material flow from the wood and stem components. This facilitates and optimizes the subsequent spatial separation of the fiber components from the wood and stem components. The method and device according to the invention meet modern requirements for productivity and quality of the product to a high degree. A particular advantage in this connection is that a tobacco cutter, which is ready for operation, can be used to cut the fibrous plant material. The use of this tobacco cutter makes it easier to separate the fiber components from the remaining material components and improves the yield considerably.
Attorney Docket: 31653-169823 The invention is explained in further detail with the aid of the drawing.

Attorney Docket: 31653-169823 The device according to the invention shown in Figure 1 is a machine known as tobacco cutter in the tobacco-processing industry. The embodiment shown is a tobacco cutter of the type KT by the company Hauni Maschinenbau AG, Hamburg. However, other types of tobacco cutters or machines of this type can also be used.
According to Figure 1, the device is used for feeding fibrous plant material 1 to a chute 2, which can be supplied with fibrous plant material, and forming a mufti-layer fibrous plant material flow from a supply not shown herein. The material 1 is fed continuously or in batches into this chute. A rake 3 that pivots back and forth cyclically in arrow direction guides the material 1 from the chute in a continuous sequence and in batches into a compressing machine 7, which consists of two pressing conveyors in the form of pressing chains 4 and 6. The endless pressing chains 4 and 6, which are arranged one above the other and converge in conveying direction {arrow 8), pick up the fibrous plant material 1 from two opposite sides. The material is then compressed and condensed to form a cake 1 l, and is conveyed to an opening 14, consisting of an upper part 12 and a lower part 13.
In the region of opening 14, the lower pressing chain 6 is guided around a toothed roller 26 and in the back region around a smooth deflection roller 27. A
corresponding toothed roller and a deflection roller for the upper pressing chain 4 are given the reference numbers 28 and 29. A drive 9 drives the pressing chains. The pressing chain 6 with its lower belt run that picks up the fibrous plant material 1 is guided over a supporting plate, which is not shown in the drawing and consists of plastic or another sliding and if possible non-abrasive material. The supporting plate is attached to a carrier Attorney Docket: 31653-169823 plate 31. A corresponding supporting plate for the upper pressing chain 4 is given the reference 32.
The opening and the pressing chains are arranged in such a way, relative to each other, that the gap 15 formed between them is as small as possible to prevent the fibrous plant material from entering the area between the opening and the pressing chain and block the pressing chain.
A pressure generator 16 acts upon the upper pressing chain 4 and is connected to a control device 20. A controlled change of the compression pressure exerted on the fibrous plant material is possible with the control device.
The lower part 13 of the opening is designed as a counter blade for blades 17, which are arranged extending approximately in axial direction along the circumference of a cutter drum 19 that can be rotated with a drive 18. During the rotation of cutter drum 19, the blades 17 cut small strips 21 of fibrous plant material from the material cake 11.
The strips 21 of cut fibrous plant material, which are separated from the material cake 1 l, drop downward in the form of a loose shower 33 and finally land inside a chute 22, through which they are conveyed to a device for separating and/or sifting and/or another type of processing. A separating or sifting device is indicated schematically in the drawing and given the reference 25.
A grinding disc 23 that is trimmed with the aid of a diamond 24 is used for sharpening the blades 17.
In place of a cutter drum with rotating blades, a cutting device with at least one cutting blade that can be moved crosswise and approximately linear to the conveying direction of the fibrous plant material cake 11 can be assigned to the output of opening Attorney Docket: 31653-169823 14. This cutting device cuts material strips 21 in the manner of a guillotine off the fibrous plant material cake 11, which process is explained with the aid of a corresponding alternative embodiment.
In place of pressing chains 4 and 6, pressing rollers that follow successively in conveying direction 8 of the fibrous plant material 1 can be used, which is not shown in the drawing. These pressing rollers are arranged in two converging rows forming a conveying path that leads to compressing zone, which narrows down.
During the operation, the fibrous plant material 1, containing for example hemp plants or the usable components of such plants, is supplied in batches or continuously to the chute 2. With its back and forth movement, the rake 3 diverts the fibrous plant material 1 in arrow direction toward the pressing machine 7, where it is picked up by the converging pressing chains 4 and 6. The pressing chains 4 and 6 convey the fibrous plant material 1 along a conveying path through the compacting zone S and toward the opening 14. In the process, the material is compressed and compacted. The pressure generator 16 that is controlled by the control unit 20 exerts the necessary pressure onto the upper pressing chain 4. The pressure of the pressing chains can be adjusted to and maintained at an optimum value by means of the control unit 20. The pressing chains 4 and compress the material 1 to form a fibrous plant material cake 11. The rotating blades 17 of the cutter drum 19 cut fibrous plant material strips 21 from this cake, which drop as shower 33 down into the chute 22 and are then transported away for further processing.
According to Figure 1, a separating or sifting device 25 is connected to the chute, which separates the fiber components and the wood and stem components in the fibrous plant material from each other, so that these can be processed separately. For the separation, Attorney Docket: 31653-169823 the fiber components in the cut fibrous plant material can be separated out and/or sifted out pneumatically or hydraulically.
Figure 2 contains a detail of a variant of the device shown in Figure 1.
Identical parts are given the same reference numbers as in Figure 1 and are not described further herein.
The variant shown in Figure 2 is designed such that immediately after cutting off the fibrous plant material strips 21 from the cake 11, a pneumatic sifting of the downward moving shower 33 takes place, which separates the lighter fiber components 34 from the heavier wood and stem components 36. Air outlet openings 39, which emit a sifting air flow 42 that is directed crosswise to the dropping direction for the fibrous plant material shower, are connected to a compressed air source 38 that is provided on the rear guide wall 37. Whereas the heavier components 36 of the shower continue to travel downward into the chute 22, the lighter components 34 are deflected by the sifting airflow to the side and into the collection chamber 41. They are removed from the collection chamber 1 ~ with the aid of known conveying means, not shown herein, for a further processing. The fibrous plant material components 36 that pass through the chute 22 can be subjected to a secondary sifting in the separating and sifting device 25, as shown in Figure 1, before they reach a device for further processing. As a result of this two-stage sifting, the fibrous material yield can be increased once more.
With the alternative guillotine-type cutter, shown in the Figures 3 and 4, elements that correspond to the previously described arrangements are given the same reference numbers, but increased by 100.
According to Figure 1, the device is used for feeding fibrous plant material 1 to a chute 2, which can be supplied with fibrous plant material, and forming a mufti-layer fibrous plant material flow from a supply not shown herein. The material 1 is fed continuously or in batches into this chute. A rake 3 that pivots back and forth cyclically in arrow direction guides the material 1 from the chute in a continuous sequence and in batches into a compressing machine 7, which consists of two pressing conveyors in the form of pressing chains 4 and 6. The endless pressing chains 4 and 6, which are arranged one above the other and converge in conveying direction {arrow 8), pick up the fibrous plant material 1 from two opposite sides. The material is then compressed and condensed to form a cake 1 l, and is conveyed to an opening 14, consisting of an upper part 12 and a lower part 13.
In the region of opening 14, the lower pressing chain 6 is guided around a toothed roller 26 and in the back region around a smooth deflection roller 27. A
corresponding toothed roller and a deflection roller for the upper pressing chain 4 are given the reference numbers 28 and 29. A drive 9 drives the pressing chains. The pressing chain 6 with its lower belt run that picks up the fibrous plant material 1 is guided over a supporting plate, which is not shown in the drawing and consists of plastic or another sliding and if possible non-abrasive material. The supporting plate is attached to a carrier Attorney Docket: 31653-169823 plate 31. A corresponding supporting plate for the upper pressing chain 4 is given the reference 32.
The opening and the pressing chains are arranged in such a way, relative to each other, that the gap 15 formed between them is as small as possible to prevent the fibrous plant material from entering the area between the opening and the pressing chain and block the pressing chain.
A pressure generator 16 acts upon the upper pressing chain 4 and is connected to a control device 20. A controlled change of the compression pressure exerted on the fibrous plant material is possible with the control device.
The lower part 13 of the opening is designed as a counter blade for blades 17, which are arranged extending approximately in axial direction along the circumference of a cutter drum 19 that can be rotated with a drive 18. During the rotation of cutter drum 19, the blades 17 cut small strips 21 of fibrous plant material from the material cake 11.
The strips 21 of cut fibrous plant material, which are separated from the material cake 1 l, drop downward in the form of a loose shower 33 and finally land inside a chute 22, through which they are conveyed to a device for separating and/or sifting and/or another type of processing. A separating or sifting device is indicated schematically in the drawing and given the reference 25.
A grinding disc 23 that is trimmed with the aid of a diamond 24 is used for sharpening the blades 17.
In place of a cutter drum with rotating blades, a cutting device with at least one cutting blade that can be moved crosswise and approximately linear to the conveying direction of the fibrous plant material cake 11 can be assigned to the output of opening Attorney Docket: 31653-169823 14. This cutting device cuts material strips 21 in the manner of a guillotine off the fibrous plant material cake 11, which process is explained with the aid of a corresponding alternative embodiment.
In place of pressing chains 4 and 6, pressing rollers that follow successively in conveying direction 8 of the fibrous plant material 1 can be used, which is not shown in the drawing. These pressing rollers are arranged in two converging rows forming a conveying path that leads to compressing zone, which narrows down.
During the operation, the fibrous plant material 1, containing for example hemp plants or the usable components of such plants, is supplied in batches or continuously to the chute 2. With its back and forth movement, the rake 3 diverts the fibrous plant material 1 in arrow direction toward the pressing machine 7, where it is picked up by the converging pressing chains 4 and 6. The pressing chains 4 and 6 convey the fibrous plant material 1 along a conveying path through the compacting zone S and toward the opening 14. In the process, the material is compressed and compacted. The pressure generator 16 that is controlled by the control unit 20 exerts the necessary pressure onto the upper pressing chain 4. The pressure of the pressing chains can be adjusted to and maintained at an optimum value by means of the control unit 20. The pressing chains 4 and compress the material 1 to form a fibrous plant material cake 11. The rotating blades 17 of the cutter drum 19 cut fibrous plant material strips 21 from this cake, which drop as shower 33 down into the chute 22 and are then transported away for further processing.
According to Figure 1, a separating or sifting device 25 is connected to the chute, which separates the fiber components and the wood and stem components in the fibrous plant material from each other, so that these can be processed separately. For the separation, Attorney Docket: 31653-169823 the fiber components in the cut fibrous plant material can be separated out and/or sifted out pneumatically or hydraulically.
Figure 2 contains a detail of a variant of the device shown in Figure 1.
Identical parts are given the same reference numbers as in Figure 1 and are not described further herein.
The variant shown in Figure 2 is designed such that immediately after cutting off the fibrous plant material strips 21 from the cake 11, a pneumatic sifting of the downward moving shower 33 takes place, which separates the lighter fiber components 34 from the heavier wood and stem components 36. Air outlet openings 39, which emit a sifting air flow 42 that is directed crosswise to the dropping direction for the fibrous plant material shower, are connected to a compressed air source 38 that is provided on the rear guide wall 37. Whereas the heavier components 36 of the shower continue to travel downward into the chute 22, the lighter components 34 are deflected by the sifting airflow to the side and into the collection chamber 41. They are removed from the collection chamber 1 ~ with the aid of known conveying means, not shown herein, for a further processing. The fibrous plant material components 36 that pass through the chute 22 can be subjected to a secondary sifting in the separating and sifting device 25, as shown in Figure 1, before they reach a device for further processing. As a result of this two-stage sifting, the fibrous material yield can be increased once more.
With the alternative guillotine-type cutter, shown in the Figures 3 and 4, elements that correspond to the previously described arrangements are given the same reference numbers, but increased by 100.
Attorney Docket: 31653-169823 The pressing device 107 of this cutting device also consists of two converging pressing chains 104 and 106, as well as a pressure generator 116 in the form of a pressing roller 143 that is arranged between the upper pressing chain 104 and the opening 114 This pressing roller can be lifted counter to the load of pressing weights 144 to relieve pressure if the pressure inside the cake 111 is too high.
A disk flywheel 147 that is driven by a motor 146 is connected to a crankshaft 148, which holds an eccentrically positioned main blade 149. At the lower end, this main blade is hinged to a guide lever 152, which can be pivoted around an axis 151 and can be moved up and down in the manner of a guillotine. Fixedly connected to the main blade 149 is a bar with scoring blades 153, which score the cake with numerous parallel scoring lines before the cake 111 is cut with the downward moving main blade 149. In this way, the material cut from a cake 111 that is pre-compacted with high pressure and consists of particularly difficult to handle, in particular hard fibrous components, is well prepared for a subsequent further processing.
