Abstract
The aim of the invention is to provide a method for producing bamboo fibre with a certain length in bulk at atmospheric temperature and normal pressure, and a device for producing the same. The method includes forming bamboo strip which integrates fibre and bamboo shoot as a whole, pressing the bamboo strip at intervals of determined length, and carrying out fibrillating after extending the inner bamboo fibre at the press position. Since the intension of the extending part of the bamboo fibre is weakened and can be naturally cut, the bamboo fibre with the same length and determined length intervals can be produced in bulk. In addition, the fibrillating can be easily performed due to weakening combination of the bamboo fibre and bamboo shoot in the bamboo strip by means of vibration, accordingly, the bamboo fibre with a burr shape can be obtained.
Description
Technical field
The present invention relates at normal temperatures and pressures the continuous method for making bamboo fibre and the manufacturing installation of the bamboo fibre of factory length unanimity in large quantities.
Background technology
Bamboo fibre is because of being natural resources and having good caking property and intensity, is the environmental protection fiber of being paid close attention to as the interior ornaments of automobile or construction material, reinforcing material.Bamboo fibre does not use separately usually, uses but be blended in the raw material such as plastic optical fibre.Use long bamboo fibre, the product that then can obtain to have good bending strength.On the other hand, use short bamboo fibre, then can improve the density of fiber, use as the product that fixedly secures screw or nail etc.In addition, because density improves during fiber finer, so, be related to the intensity that improves product.And, if bamboo fibre is the burr shape, interweaving well with the material compatibility of sneaking into, conjugation improves, so, can obtain the higher product of intensity.Like this, according to the purposes of various products, need have consistent length, certain thickness and two ends is the bamboo fibre of burr shape.
As the acquisition methods of bamboo fibre, main knownly have the energy that applies HTHP and Fibrotic method (for example, patent documentation 1), or use fiber uncoiling machine and Fibrotic method (for example, patent documentation 2～4).
In patent documentation 1, become non-pressurised state with the bamboo wood under 140 ℃～200 ℃ the heating pressurized state is instantaneous, make bamboo wood quick-fried broken, thereby obtain bamboo fibre for fibrous.
In patent documentation 2, preparation is cut to the bamboo wood of specific length, after this bamboo wood pulverized by rolling device is preliminary, use rag shaker (anti-Mao Machine) separates fibre, further, use turbine type grinding mill fibrillating, thereby the acquisition average length is 25cm, the average diameter bamboo fibre less than 0.4mm.
In patent documentation 3, use conveying roller crushing bamboo chip, and after decomposing fiber, use the cutting edge roller vertically and transversely cutting off.By the side from fiber uncoiling machine it is sent into, separate fibre the impeller and the separating between the very thin groove of urceolus of the inner core of fiber uncoiling machine, by being arranged at the slit of urceolus, fibre diameter attenuates, and discharges bamboo fibre from slit, thereby obtains the bamboo fibre of certain thickness.
In patent documentation 4,, after bamboo chip damaged by pressure and cut off, obtain bamboo fibre thereby use screen cloth that bamboo fibre is separated with micro mist by the roller that bamboo chip is made by rubber repeatedly.
Patent documentation 1:(Japan) spy opens the 2003-253011 communique
Patent documentation 2:(Japan) spy opens flat 5-138617 communique
Patent documentation 3:(Japan) spy opens the 2000-71209 communique
Patent documentation 4:(Japan) Te Kaipingdi 4-307203 communique
In patent documentation 1, must under HTHP, handle, do not apply high-energy if exist, can not Fibrotic problem.
In addition, because by quick-fried broken the acquisition, so can not obtain the bamboo fibre of desired length and thickness.
And, under 140 ℃～200 ℃ high-temperature and high-pressure conditions, handle bamboo wood, as the lignin (リ グ ニ Application) of bamboo wood constituent when apply surpass 85 ℃ heat after, chemical reaction takes place, generate gases such as formaldehyde.Therefore, the bamboo fibre of acquisition becomes the bamboo fibre that formaldehyde takes place, and is disadvantageous to environment.
In patent documentation 2, only use rag shaker that bamboo wood is separated fibre, used turbine type grinding mill fibrillating, because do not regulate the operation of length of bamboo fibre, so existence can not obtain the problem of the bamboo fibre of desired length and length unanimity.
In addition, it is rolling to carry out punching type etc., because the rolling scar that produces on bamboo fibre easily, has the problem of the weakened of bamboo fibre self.
In patent documentation 3, the length of using cutting edge to cut off bamboo chip and regulate fiber.Therefore, cause the two ends of fiber to become sharp keen section, so, when it being blended in the raw materials such as plastic optical fibre, be difficult to interweave with raw material, in conjunction with a little less than.Therefore, existence can not obtain the problem of the bamboo fibre that can use in the construction material of desired strength etc.
In patent documentation 4,,, can not obtain the fiber of specific length scope so the length of fiber is inhomogeneous just because of bamboo chip obtains bamboo fibre repeatedly by roller by damaging by pressure.
In addition, for the same reason, the thickness of fiber is also inhomogeneous, so can not obtain to expect the fiber of thickness.
Like this, at normal temperatures and pressures, making within the specific limits continuously in large quantities, the method and apparatus of the bamboo fibre of length unanimity did not also have to realize in present stage.

The specific embodiment
With reference to Fig. 1～Fig. 4, method for making bamboo fibre of the present invention is described.
Shown in the process chart of Fig. 1, first embodiment of method for making bamboo fibre of the present invention mainly comprises: the operation of formation bamboo chip, the operation with the bamboo fibre in the predetermined distance elongation bamboo chip, the operation of separating fine bamboo chip.
At first explanation forms the operation of bamboo chip.
Shown in Fig. 2 (A), the bamboo wood cross section is circular, and inside is the structure of hollow.And, be dispersed with from the conduit of subterranean stem transporting water, inorganic matter brokenly and carry the screen casing (Division pipe) etc. of the nutritional labeling that obtains by photosynthesis to manage 12.This pipe 12 is used as bamboo fibre.Bamboo meat 13 is filled between these pipes 12.Managing 12 intensive epidermis 14 sides that are present in bamboo wood, mainly is in the scope of the thickness direction 2/3 that begins from epidermis 14 sides, exists hardly in endothelium 15 sides, and bamboo meat 13 occupies major part.
At first, remove the branches and leaves of the bamboo of felling, cut off along the direction vertical with the direction of growth.Cut apart the bamboo of this cut-out along diametric(al), remove the ring protuberance of the bamboo of cutting apart, form the bamboo chip 11 shown in Fig. 2 (B).Its result, bamboo chip 11 is extended with bamboo fibre along its length.And, also can remove the endothelium of this bamboo chip and crust and use.The length of bamboo chip 11 and width cut off, are divided into easy to handle length and width.
Though need not consider the bamboo kind used especially, the bamboo that optimum fiber matter is many, for example cizu (cizu) etc.When using cizu, the length of bamboo chip is 1～2m, and the width of bamboo chip is approximately 30mm, and thickness approximately is about 4～6mm.
Then, the elongation operation of extending the bamboo fibre 12 in the bamboo chip 11 with predetermined distance is described.
Fig. 3 is the side schematic view of bamboo chip 11 in the operation of elongation bamboo fibre 12, as shown in the figure, with predetermined distance in the epidermis side of bamboo chip 11, promptly push as shown by arrows from bamboo fibre 12 sides.Bamboo meat 13 sides are fixing by hard stand etc., so the bamboo meat 13 of pushing the position caves in because of being compressed.Bamboo fibre 12 can weaken to the elongation of bamboo meat 13 sides along this depression.
This operation is an operation as feature of the present invention, by use be provided with projection by pressure roller, push bamboo chip 11 from bamboo fibre 12 sides, bamboo meat 13 is roughly crushed, bamboo fibre 12 machinery is upheld the thickness of bamboo chips 11.In addition, be made as necessarily by the height with projection, the extended length of bamboo fibre 12 becomes necessarily, thereby can make the reduction of the bamboo fibre 12 of pushing the position certain.
In addition, in this operation, by selecting the interval of projection, thereby can select the length of the bamboo fibre 12 that obtains.Though bamboo fibre 12 can be selected length according to purposes,, in most cases in 10～120mm scope, select.
And, in separating fine operation, carry out the fibre of separating of bamboo chip 11, take out bamboo fibre 12.In preceding operation, because of being weakened in the intensity of pushing position bamboo fibre 12, so, cut off naturally when separating fibre at this position.If suitably set the predetermined distance of pushing the position of bamboo fibre 12, can select the length of the bamboo fibre 12 that obtains, so, can optionally make the bamboo fibre 12 of necessary length in a large number.
When separating fibre, can use described later, separating the fiber uncoiling machine that fine cylinder surface is provided with a plurality of blades or wire etc.By blade or wire, the bamboo meat 13 of bamboo chip 11 is scraped and is revealed bamboo fibre 12.The part of bamboo fibre 12 is clamped between the blade or between the wire, is stretched by the rotation of separating fine cylinder.By this tensile stress, blocked naturally at the position of pushing of bamboo fibre 12.Bamboo fibre 12 uses fiber uncoiling machines mechanically to stretch and tears, so, this section elongation, tear and form the burr shape.
Fig. 4 is the side view of separating fine working procedure states of explanation bamboo fibre 12, the elongation state when Fig. 4 (A) expression bamboo fibre 12 is separated fibre, and the state of each bamboo fibre 12 that blocks behind the fibre is separated in Fig. 4 (B) expression.
In Fig. 4 (A), bamboo fibre 12 is stretched when separating fibre, pushing the position as shown by arrows, is subjected to tensile stress from both direction.This bamboo fibre 12 push the position, die down because of bamboo fibre 12 attenuates, thus since tensile stress block naturally.
In Fig. 4 (B), because of pushing the stretching of position use fiber decomposition device, tearing mechanically and blocked, so can make two ends is each bamboo fibre 12 of burr shape.
Then, with reference to Fig. 5, Fig. 6, second embodiment of method for making bamboo fibre of the present invention is described.
Shown in the process chart of Fig. 5, second embodiment mainly comprises: the operation, the operation with the combination of the operation of the bamboo fibre in the predetermined distance elongation bamboo chip, bamboo fibre in the reduction bamboo chip and bamboo meat, the operation of separating fine bamboo chip that form bamboo chip.In aforesaid first embodiment of the invention, appended the operation of the combination of interior bamboo fibre of the bamboo chip that weakens and bamboo meat.
About the operation that forms bamboo chip, operation, the operation of separating fine bamboo chip with the bamboo fibre in the predetermined distance elongation bamboo chip, because of with aforementioned first embodiment in identical, so in this description will be omitted.
The operation of reduction bamboo fibre and the combination of bamboo meat is described.
In bamboo chip 11, because of bamboo meat 13 combine with bamboo fibre 12 attached thereto, so, separate in the fine operation ensuing, use fiber uncoiling machine can not carry out separating of bamboo fibre 12 and bamboo meat 13 effectively, and be created on the bamboo fibre 12 that is combined with bamboo meat 13 on the bamboo fibre 12.In order to prevent this situation, in advance before separating fine operation, insert this operation of the combination of be used to weaken bamboo fibre 12 and bamboo meat 13.
In this operation, bamboo chip 11 is applied vibration and the combination of reduction bamboo fibre 12 and bamboo meat 13.Can find out also that from Fig. 2 bamboo fibre 12 is in the epidermis side of bamboo chip 11, bamboo meat 13 is at the opposition side of this epidermis side, so preferable methods is that the epidermis side from bamboo chip 11 applies vibration and the combination of reduction bamboo fibre 12 and bamboo meat 13.Be described in detail in manufacturing installation described later about concrete method.
Fig. 6 (A) is the schematic diagram of the state of expression reduction bamboo chip 11 interior bamboo fibres 12 and 13 combinations of bamboo meat.In this figure, by vibration, the combination of bamboo fibre 12 and bamboo meat 13 is weakened, and produces the gap and separate between bamboo fibre 12 and bamboo meat 13.Therefore, can easily separate fibre ensuing separating in the fine operation, thereby can take out thin bamboo fibre 12.
Fig. 6 (B) is the schematic diagram that bamboo fibre 12 states behind the fibre are separated in expression.In this operation, own by vibration bamboo fibre 12, surperficial integral body can be become the burr shape.Thus, can improve combination between the bamboo fibre 12.
With reference to Fig. 7～Figure 12, bamboo fibre manufacturing installation of the present invention is described.Fig. 7 is the side view of expression bamboo fibre manufacturing installation summary of the present invention, Fig. 8 be according to of the present invention, by the enlarged drawing on pressure roller surface, Fig. 9 is the state of bamboo fibre of the present invention is extended in expression according to the present invention a schematic diagram, and Figure 10 is an enlarged drawing of separating fine cylinder surface of the present invention.Figure 11 is an expression plane of separating the blade configuration status of fine cylinder of the present invention.Figure 12 is to use fine cylinder is separated fibre to bamboo chip the state diagram of separating of the present invention.
As shown in Figure 7, this manufacturing installation 1 is made of press device 2, fiber separation device 3, fiber decomposition device 4.
, send into as shown by arrows transporting on the platform 23 up by conveying roller 21 by in the pressure roller 22 with the bamboo chip fiber side.On by pressure roller 22, be formed with projection, push the bamboo chip of sending into, at the position elongation bamboo fibre that part is being pushed by the projection of predetermined distance with the interval of stipulating.Therefore, will by pressure roller 22 with transport platform 23 and separate, it is made as at interval than about the thinner 5mm of the thickness of bamboo chip.
The enlarged drawing of pressure roller 22 is pressed in expression among Fig. 8.On the surface of pressing pressure roller 22, in the direction vertical with the throughput direction of bamboo chip, being formed with the cross section with predetermined distance is hemispheric projection 25.Press pressure roller 22 is squeezed broken bamboo chips by projection 25 while rotating bamboo meat, the bamboo fibre of bamboo chip inside partly extends and weakens.
Because of the effect of projection 25 is bamboo fibres of pushing and squeezing broken bamboo chip elongated internal, so use metal such as iron to get final product.In the present embodiment, the interval of projection 25 is made as 60mm, at this moment, can obtain the following bamboo fibre of about 60mm.By changing the interval of projection 25, can make the following bamboo fibre of gap length.In addition, the thickness of projection 25 is made as, and makes its bamboo meat of cutting bamboo chip and compressing inside, thus the thickness of the bamboo fibre that can weaken.In the present embodiment, the thickness of considering the bamboo chip of use is about 4～6mm, and the thickness of projection 25 is made as 3mm.By changing the thickness of projection 25, can select the elongation degree of bamboo fibre, thereby can select the reduction degree of bamboo fibre.
Transporting platform 23 is the metal platforms that are provided with the groove wideer a little than the width of bamboo chip in order to transport bamboo chip, and the bamboo chip epidermal area is passed through this groove up continuously.
Fig. 9 represents to use projection 25 to push bamboo chip 11 and the schematic diagram of the state of elongated fibers.Bamboo chip 11 with the epidermis side up state and by press device 2.As shown in Figure 2, because of there is bamboo fibre 12 in bamboo wood in the epidermis side, by from epidermis side push projection 25, bamboo meat 13 is squeezed broken, and bamboo fibre 12 is pressed in this groove and elongation bamboo fibre 12.
Conveying roller 31 will be transported to by the bamboo chip of press device 2 and transport platform 34, keep the epidermis side of bamboo chip to be transported to fiber separation roller 32,33 up.
The vibration frequency of supplying with from vibration feedway 35,36 is 5～15Hz.Vibration ratio 5Hz hour, the combination of then can not fully weaken bamboo fibre and bamboo meat, thus the fibre of separating that can not easily carry out is subsequently operated.When vibration ratio 15Hz was big, the combination of bamboo fibre and bamboo meat was excessively weakened, and caused the blade 45 of fiber decomposition device 4 to be absorbed in the bamboo chip, thereby can not cut bamboo meat gradually and take out thin bamboo fibre.
In the present embodiment, fiber separation roller 32 nearly weighs 30kg greatly, and fiber separation roller 33 weight become about 40kg.Use lighter initial fiber separation roller 32 transmitting vibrations, the bamboo fibre the scope of reduction from the bamboo fibre side to a half thickness and the combination of bamboo meat.Then, use second heavier fiber separation roller 33, the bamboo fibre in the scope of reduction residue one half thickness and the combination of bamboo meat.So, weaken, thereby can realize that the bamboo fibre in the bamboo chip and the combination of bamboo meat weaken to a certain degree by changing two stages of weight fraction.
In addition, because of fiber separation roller 32,33 is installed at above-below direction with moving freely, even if there is the difference of thickness in the bamboo chip that transports, because of constant weight is applied to the bamboo chip upper surface always, so, can apply the vibration of certain intensity to whole bamboo fibres in the bamboo chip and bamboo meat, thereby can easily separate fibre.
Conveying roller 41 the bamboo chip that platform 34 carries of transporting of operations in the past is transported to and transports platform 43, and is transported to and separates fine cylinder 42.
Separate fine cylinder 42 its surfaces and be provided with a plurality of blades 45, draw the bamboo chip at quarter, eliminate bamboo meat, take out bamboo fibre simultaneously at length direction.
In addition, as previously mentioned, because bamboo chip is at the weakening strength of the position bamboo fibre of being pushed by press device 2, so be cut off naturally at this position.Therefore, obtain the following bamboo fibre of predetermined distance serially, simultaneously, the two ends of bamboo fibre become the burr shape.
The enlarged drawing at the main position of fine cylinder 42 is separated in expression among Figure 10.In the present embodiment, being provided with a lot of height on the surface of separating fine cylinder 42 is the blade 45 of 8mm, carries out the fibre of separating of bamboo chip by this blade 45.
In the present embodiment, the surface of separating fine cylinder 42 is a timber 46.Because of timber 46 absorbs impact when separating fibre, so can prevent blade 45 tippings or fracture.The ring part of bamboo chip is hard, and as if thin blade 45 these parts of cutting of used thickness, blade 45 can be damaged because of bending, but because of the surface of separating fine cylinder 42 is a timber 46, so the timber 46 of the cutter root portion of blade 45 is out of shape and relaxes and impact.Therefore, but the thin blade 45 of used thickness.If the blade 45 that used thickness is thin can little by little cut off the bamboo meat between the bamboo fibre, can take out thin bamboo fibre.
Figure 11 is a plane of separating the main position of fine cylinder 42.Dotted line represents to separate the axle of fine cylinder 42, when the below of bamboo chip from figure sent into, is that the center rotates as shown by arrows with the axle.Separating the axial of fine cylinder 42,, a little dispose with the direction of rotation of separating fine cylinder 42 with the arranged spaced blade 45 of 2～3mm with being offset.Because of offset configuration blade 45, so the blade 45 that contacts with bamboo chip is offset at leisure with the width of 2～3mm, little by little eliminates bamboo meat.In the present embodiment, because of the width of bamboo chip is approximately 30mm, so, separate during the rotation of fine roller 42, contact with blade 45 about 10～15 incessantly and eliminate bamboo meat, seamlessly the width of about 30mm is separated fibre.
Reveal bamboo fibre by cutting bamboo meat at leisure.Bamboo fibre is clamped between the blade 45 of skew and is stretched.The bamboo fibre that is stretched is because of pushing the weakening strength at position, so, torn naturally at this position.Like this, torn naturally because of bamboo fibre pushing the position, thereby taken out the bamboo fibre of length unanimity serially.
In addition, because of mechanically being torn pushing the position, so the section tension fracture of bamboo fibre forms the burr shape.
The blade 45 that used thickness is thin, and, the axially spaced-apart of separating fine cylinder 42 is narrowed down, replacement is provided with the fine cylinder 42 of separating of blade 45 and uses, and can take out thinner bamboo fibre.In the present embodiment, the blade 45 that used thickness is thin is made as the configuration of 2～3mm ground with the axially spaced-apart of separating fine cylinder 42, and can obtain diameter is 100 μ m～500 bamboo fibres μ m, so-called tiny diameter.
The blade 45 that used thickness is thin narrows down the axially spaced-apart of separating fine cylinder 42 and disposes, and can little by little eliminate the bamboo meat of imbedding between the bamboo fibre, becomes thin bamboo fibre.Then, the thin bamboo fibre of clamping only between the blade 45 of biasing, the bamboo fibre that stretches by the rotation of separating fine cylinder 42 are torn pushing the position.Like this, can take out thinner bamboo fibre.
And then, explain the fibre of separating of bamboo chip with reference to Figure 12.
Figure 12 (A) sends bamboo chip into the state of separating in the fine cylinder 42.Separate the rotation in the counterclockwise direction in this figure of fine cylinder 42, cut at leisure from the top of bamboo chip.
Figure 12 (B) is the state of cutting bamboo chip 11.Because of blade 45 disposes in the direction of rotation skew of separating fine cylinder 42, so the bamboo meat 13 of bamboo chip is all eliminated and reveals bamboo fibre 12.
Figure 12 (C) expression bamboo fibre 12 intercepted states.Adjacent blade 45 on the direction of rotation of separating fine cylinder 42 is offset a little on the direction of rotation of separating fine cylinder 42 and is provided with.If with the degree among the distance that can be clamped in this skew, carefully separate fibre, then bamboo fibre 12 is clamped between this blade 45 with bamboo fibre 12.The bamboo fibre 12 that is held is wound on to be separated on the fine cylinder 42, simultaneously, and because of the rotation of separating fine cylinder 42 is stretched.Then, structure is, because this tensile stress, tears naturally and falls at the position that the intensity of bamboo fibre 12 is weakened.
Behind fiber decomposition device 4, bamboo fibre and bamboo meat are collected in plummer 51.Plummer 51 is provided with fiber and accepts net 52, bamboo fibre is stayed fiber accept in the net 52, on the other hand, makes under the downward clan of bamboo meat, thereby isolates bamboo fibre.
