Description N oF
This invention relates to a mechanical fiber extraction machine and method for continuously extracting fibers from complete stalks of a fiber-containing vegetable raw material, preferably from abaca stalks.
Abaca (scientific name: musa textilis nee) is a plant that is indigenous to the Philippines and its fiber is known as “Manila hemp”. The fiber is obtained from the leaf sheaths of the abaca plant and the abaca fiber is particularly strong and can be used as a raw material for cordage, fiber grafts So and pulp for the production of specialty paper products like 5 security papers, teabags, filter papers, cigarette papers, 3 meat and sausage casings, non-woven and other thin printing ! papers.
The abaca plant includes plural leaf sheaths, wherein : the outer leaf sheaths represent the older ones and the inner ] leaf sheaths the younger ones. The fibers are embedded in an outer layer of these leaf sheaths which is called “tuxy”. ]
During harvest the abaca stalks are cut close above the soil and the leaf sheaths are traditionally separated from the ] stalk before further processing. :
To extract the fibers from the leaf sheaths three basic principles are commonly used: ] (1) In “hand-stripping” the leaf sheaths of the stalk 30 . are manually separated from each other. Then, the fiber containing layer or “tuxy” is separated from the leaf sheaths. The tuxies are stripped in that they are manually § pulled between a block and a knife. ] (2) Using a so-called “spindle stripping machine” the 1 pulling force that is typically applied by hand in the method under (1) is replaced by a rotating spindle which increases / the throughput by approximately five times. 1 oy 2 (3) An alternative method without separating the tuxies from the leaf sheaths is decortication using the separated leaf sheaths as the raw material. Typically, a so-called decorticator is applied for the purpose and in this process the isolated leaf sheaths are processed without separating the fiber-containing layer (tuxy) from the upper side of the leaf sheath.
The above-existing methods are disadvantageous in a number of aspects. First, the amounts of tuxy recovered by weight of the stalk and the quantity produced by unit of time are largely dependent on the skill of the worker. Second, the use of existing tuxying knives and the manual process is not user-friendly. The use of the “decorticator” increases the ratio of fibers recovered from the plant but still involves a ; lot of manual labor in preparing the stalks of the plant for i : the process, which involves the separation of the leaf : sheaths from the stalk.
The present invention aims at further increasing the throughput and the exploitation rate of fibers from the plant : and to make the process less tedious.
To solve that problem the present invention provides a mechanical fiber extraction machine for continuously ] extracting fibers from complete stalks of a fiber-containing vegetable raw material, preferably abaca, comprising the ‘ features of claim 1 and a corresponding method for mechanically extracting fibers continuously from such ] complete stalks comprising the features of claim 13.
Preferred embodiments of the mechanical fiber extraction 5 machine and of the method are defined in the dependent claims.
The invention accordingly concerns a mechanical fiber : extraction machine for continuously extracting fibers from i stalks of a fiber-containing vegetable raw material, ] preferably abaca, comprising a feeding device for supporting the stalks and guiding the stalks to a cutter device for ; separating the stalks into plural segments in the ;
oo : 3 longitudinal direction; a crusher device provided downstream of the cutter device for applying crushing pressure onto the stalk segments fed from the cutter device to break up the cells of the material; a spreader device for two- dimensionally spreading and flattening the stalk segments that have passed the crusher device; a cleaning device arranged downstream of the spreader device, the cleaning device including a shearing edge around which the flattened stalk segments are guided, and a rotatable cleaning and brushing roll arranged so as to pass the flattened stalk segments between its outer periphery and the shearing edge and simultaneously brush out pulpy stalk material from the vegetable fibers due to a relative movement with respect to the fibers; a retarding device for retarding the transport of the flattened stalk segments upstream of the cleaning device; b ] and an output device for receiving the fibers downstream of . J the cleaning device and guiding the fibers out of the machine.
In the mechanical fiber extraction machine the cutter device may preferably comprise plural rotary blades in spaced apart arrangement and/or the crusher device my comprise a ; pair of confronting and mutually engaging rotatable crusher 1 rolls, preferably provided on the outer peripheral surfaces with protrusions like ridges, bars, teeth, needles and/or recesses, and/or the spreader device may comprise a pair of confronting rotatable rolls pinching the stalk segments for 4 two-dimensionally spreading and flattening the stalk segments, and/or the retarding device may comprise rolls or bands between which the flattened stalk segments are pinched, preferably with roughened peripheral surfaces and ] rotating/moving at a slower peripheral speed than the ] brushing roll of the cleaning device (5) located immediately ] downstream thereof, and/or the output device may comprise a ] conveying mechanism for actively conveying the fibers out of / © 35 the machine. i
The conveying mechanism preferably comprises a conveyor ] belt provided with a vibration and sieving function to 1 separate loose stalk material from the fibers during the conveyance.
The mechanical fiber extraction machine may comprising at least one further cleaning device arranged downstream of the first cleaning device, the at least one further cleaning device including a shearing edge around which the flattened stalk segments are guided, and a rotatable cleaning and brushing roll arranged so as to pass the flattened stalk segments between its outer periphery and the shearing edge and simultaneously brush out pulpy stalk material from the vegetable fibers due to a relative movement with respect to the fibers. In this case a further retarding device for retarding the transport of the flattened stalk segments may be provided upstream of the further cleaning device. ;
In the mechanical fiber extraction machine the brushing | 1 1 roll of the cleaning device(s) is preferably provided with . protrusions, preferably ridges, bars, teeth, and/or needles, i on the outer peripheral surface.
Further, all devices for processing the stalks and fibers along the conveyance path through the machine are ] designed to operate continuously.
The invention also concerns a process for continuously J extracting fibers from stalks of a fiber-containing vegetable raw material, preferably abaca, comprising a step of 1 separating the stalks into plural segments in the longitudinal direction by cutting; a step of applying crushing pressure onto the cut stalk segments to break up the 1 cells of the material; a step of two-dimensionally spreading ] and flattening the stalk segments after the crushing step; a step of cleaning the spread and flattened stalk segments by 4 passing the flattened stalk segments between an outer periphery of a rotating cleaning and brushing roll and a shearing edge to simultaneously brush out pulpy stalk ] material from the vegetable fibers due to a relative movement i 1 35 between with outer periphery of a rotating cleaning and ; brushing roll and the fibers caused in that the transport of ] : i i
. the flattened stalk segments is retarded upstream of the shearing edge.
The invention teaches an essentially fully automated machine and process that comprises the extraction of the fibers from the leaf sheaths from the complete stalk in a single process line without requiring a previous separation of the leaf sheaths. The mechanical fiber extraction machine and process of the invention extracts, in a continuous process, the fibers from the complete stalks by a number of consecutive mechanical treatment steps. The throughput using the fiber extraction machine and process of the invention is about 80 to 40 times higher than currently existing methods.
The sequence of process steps of the mechanical treatment. also involves reduced fiber loss, provides a more - homogenous fiber quality and allows for an adjustment of the 5 degree of fiber opening and cleaning so that one can now : determine and set the quality of the fibers extracted in the 1 process. This can be achieved by setting the machine parameters, i.e. the transport speed, the pressures or gaps at the various units and roller pairs and/or by exchanging the rollers in certain units against rollers that have a different surface topology. Thus, a certain set and predetermined fiber quality can be repeatedly produced.
Further, since no manual interaction is involved between : 25 the feeding of the complete stalks into the machine/process i and the output of the cleaned fibers at the end of it, the process avoids dangerous work for any worker. ]
The fiber extraction machine of the invention can be i realized as a stationary process line but can be also mounted on a vehicle chassis, i.e. a trailer or the bed of a truck, so that the effective process can be carried out on-site where the plants are grown and harvested. This avoids transport of the harvested stalks, storage, handling, energy ] and space for these processes, so that the machine and ] , 35 process of the invention are overall more efficient and ] environmentally friendly. 1

The fiber extraction machine and process of the present 5 invention will now be described in detail on the basis of the : ] drawing whereby the detailed description and representation of the machine should not be understood as a limitation to the particular machine but to rather serve as a general explanation of the concept of the present invention.
The mechanical fiber extraction machine 100 of the invention for continuously extracting fibers from complete stalks of a fiber-containing vegetable raw material like abaca can be roughly separated into three basic function units or process blocks which are identified in the machine of Fig. 1 as unit 1, unit 2, unit 3. Unit 1 concerns the fragmentation of the complete stalk in longitudinal direction, unit 2 concerns the breaking or crushing of the i cells and the flattened distribution of the fiber material, and unit 3 concerns the cleaning and extraction of the non- / fiber sheath material. Further units may be provided upstream ] of unit 1 and downstream of unit 3 to handle the stalks or i extracted material. In addition, intermediate units and : process steps can be provided to effect additional processing if desired.
The unit 1 includes a feeding device in the form of a i feeding table 1 for supporting the complete stalks and !
: , guiding the stalks to a cutter device 2 for separating the stalks into plural segments in the longitudinal direction.
The feeding device can be simply a mechanical support on which the stalks are placed and guided manually through the cutter device 2 or can extend further upstream of the cutter device and can be provided with mechanical conveying means like chains, belts, bands or rollers or combinations thereof with guides arranged as desired and driven to convey and feed the complete stalks to and through the cutter device.
The cutter device 2 as shown in Figs. 1 and 2 comprises : : plural rotary blades 2A in spaced apart arrangement. In ] principle, knives of different type can be used provided they are suitable to separate the stalks into the plural segments in the longitudinal direction. For example, cutting rings, . linear-moving knives, band-knives or saws, cutting strings E etc. are equally applicable. - ]
Once the stalks have passed the cutter device the segments are dispersed and are, in this dispersed posture, : fed to the functional unit 2. This unit 2 comprises a crusher ] device 3 provided downstream of the cutter device 2 for applying crushing pressure onto the cut stalk segments fed from the cutter device 2 to break up the cells of the ; material. The crusher device 3 comprises a pair of confronting and mutually engaging rotatable crusher rolls 3A, J preferably provided on the outer peripheral surfaces with ] protrusions 3a, 3b like ridges, bars, teeth and/or needles, etc., or combinations thereof. The functional purpose of the i crusher device is to apply a vertical pressure onto the / severed stalk segments. Consequently, the form and number of 1 protrusions are variable as long as they provide this ] vertical pressure. Alternatively, or in addition, the ; vertical pressure can be applied by means of a plate or a ] ‘ pair of plates intermittently pressed against each other by ; hydraulic or mechanical force and likewise provided with protrusion of the above-mentioned type on their confronting 1 surfaces. 1
A further element of the functional unit 2 is a spreader device 4 arranged downstream of the crusher device 3 and provided for two-dimensionally spreading and flattening the stalk segments that have passed the crusher device 3. The spreader device 4 preferably comprises a pair of confronting rotatable rolls 4A pinching the stalk segments for two- dimensionally spreading and flattening the stalk segments pinched therebetween. The purpose of this spreader device 4 is to still further laterally spread and distribute the stalk material. .
Downstream of the spreader device 4 and functionally associated with the unit 2 is a retarding device 6 for retarding the transport of the flattened stalk segments having passed the spreader device 4. This retarding device 6 imparts a certain holding force onto the stalk material for yg the next process located in the functional unit 3. The ; retarding device 6 preferably comprises a pair of rollers 6A with surfaces provided with features that increase friction ] with respect to the stalk material, i.e. the surfaces may be provided with grooves or friction-increasing coatings like rubber etc.. Downstream of the retarding device 6 the sheath material has assumed the structure of a fiber/stalk material carpet as shown in Fig. 3. ]
The functional unit 3 is arranged immediately downstream : of the retarding device 6 and comprises a shearing edge 5A around which the flattened stalk segments are guided, a rotatable cleaning and brushing roll 5B arranged so as to ] pass the flattened stalk segments between its outer periphery and the shearing edge 5A and simultaneously impart a pulling i force on the material and brush out pulpy stalk material from the vegetable fibers due to a relative movement with respect 3 to the fibers. As shown in Fig. 4 the shearing edge 5A is the i : counterpart for the cleaning and brushing roll 5B and can have any suitable geometry like flat, rectangular or rounded : edges and it serves to present the flattened stalk segments to the surface of the cleaning and brushing roll 5B.
The shearing edge 5A of the cleaning device 5 (and of any optionally provided further cleaning device described later) can be in the form of a rotatable roller as shown in the drawing but can also be a fixed or substantially fixed bar or blade-like member with suitable cross section and surface properties.
Downstream of the engagement position between the shearing edge 5A and the rotatable cleaning and brushing roll 5B there is preferably arranged a further pair of holding rollers 9A, 9B which receive the extracted fibers and cooperate to hold the fibers and pull the fibers towards the next process step. As shown in the right half of Fig. 5 these holding rollers simultaneously serve to remove the pulpy stalk material from the ends of the fibers of a particular : stalk segment. The holding rollers can be replaced by 3 conveying belts cooperating with each other so as to pinch ; ~ the fibers therebetween or by plural pairs of rollers. ]
The cleaning and brushing roll 5B serves to shear off the unwanted stalk material from the fibers. For this : purpose, the brushing roll is provided with protrusions, preferably ridges, bars, teeth and/or needles on the outer peripheral surface or combinations thereof.
Downstream of the cleaning and brushing roll, depending on the desired level of cleaning, a conveying mechanism 7 is ] provided for receiving the fibers and conveying the fibers out of the machine. The conveying mechanism 7 preferably comprises a conveyor belt 7A provided with a vibration and sieving function to separate loose stalk material from the fibers during the conveyance. As shown in Fig. 5, the : conveying mechanism is directed towards the entry side of the J machine so that the overall length of the machine can be shortened. A conveyance direction to the rear side is also ; feasible. In a most basic concept as the conveying mechanism 7 for receiving the fibers downstream of the cleaning device ; 5 and conveying the fibers out of the machine a chute or ; guide can be provided that is inclined towards an output ; position. Accordingly, the active conveyance and the :
simultaneous vibration and sieving functions are optional but preferred to remove the loose stalk material from the fibers.
In a preferred embodiment shown in Fig. 5 a second cleaning device 8 can be arranged downstream of the first cleaning device 5 and this second cleaning device 8 can be formed basically similar to the first cleaning device, i.e. it can include a shearing edge 8A around which the flattened stalk segments coming from the first cleaning device are guided and a rotatable cleaning and brushing wall 8B arranged so as to pass the flattened stalk segments between its outer periphery and the shearing edge 8A and simultaneously brush out pulpy stalk material from the vegetable fibers due to the relative movement with respect to the fibers. The structure of the shearing edge and of the cleaning and brushing roll - can be the same as described above in connection with the | 3 first cleaning device. :
Also, a further dedicated retarding device 9 can be provided upstream of the second cleaning device 8 for ] retarding the transport of the flattened stalk segments.
Further preferably, guide rolls 10 can be provided to align and maintain the transport direction of the fibers towards the shearing edge of the second cleaning device.
Further cleaning stages in the form of similar cleaning ] devices can be arranged downstream of the second cleaning device if desired for increasing the cleaning level of the fibers. 3
The function of the retarding device 9 upstream of the i second cleaning device 8 can be performed by the holding rolls 9A, 9B described above. ]
Downstream of the engagement position between the ; shearing edge 8A and the rotatable cleaning and brushing roll 8B there is preferably arranged a further pair of holding ; rollers 9A, 9B which receive the extracted fibers and ] cooperate to hold the fibers and pull the fibers towards the next process step, i.e. a gtill further cleaning device or the conveying mechanism 7 is provided for receiving the { fibers and conveying the fibers out of the machine. ;
’ 11
Essentially all elements for processing the stalks and fibers along the conveyance path through the machine are designed to operate continuously.
While a preferred embodiment of the invention has been described.in connection with the Figures, it is apparent that variations from the specific structures are within the range ' of the skilled person without departing from the scope and concept of the present invention.
The mechanical fiber extraction machine and process of the present invention provides a considerably higher throughput, is less labor-intensive, involves reduced fiber loss and considerably improves the evenness of the fiber quality. Also, since no manual labor and involvement is necessary after the feeding of the stalks into the machine : and until the cleaned fibers are output through the conveying a mechanism, a higher security for operators is provided. :
Since the functional units of the machine are located immediately in sequence, the whole machine is compact and can be transported, preferably in that it is mounted or mountable : on a vehicle chassis or frame, like the trailer shown in Fig. 1. It can also be shielded to the environment by a casing surrounding the functional units (not shown in the drawing). i
