Technical field
The present invention relates to the structures for the hollow guide shaft body that Spindleless spinning machine has.
Background technology
It is me to generate the air flow spinning apparatus of spinning to the fibre bundle twisting by acting on turn air stream to fibre bundle
It is known.
Air flow spinning apparatus has mandrel(Or hollow guide shaft body).The mandrel has cylindric or coniform shape,
Space as defined in being formed around the mandrel(Turn room).In air flow spinning apparatus, by the fibre of turn air stream effect
It ties up in being waved around mandrel in turn room.It is twisted as a result, to fiber, generates spinning.
In this way, since fiber is waved around mandrel, friction is generated between mandrel and fiber.Therefore,
The mandrel of air flow spinning apparatus requires wear resistance.In addition, in fiber industry, it is desirable that the component of wear resistance is generally using fine
Ceramics.Therefore, the mandrel of fine ceramics is used in previous air flow spinning apparatus.Has the air-flow of mandrel made of ceramics
Spinning apparatus is documented in such as Japanese Unexamined Patent Publication 10-317231 bulletins.
In recent years, it is desirable to spinning speed higher speed.In air flow spinning apparatus, in order to improve spinning speed, having makes twirl
Return necessity that the turn speed of indoor fiber rises.Therefore, it may be considered that by making the radius of mandrel become smaller(Mandrel is set to attenuate)
So that the turn radius of fiber is become smaller, the turn speed of the fiber is made to increase.
But the mandrel that previous air flow spinning apparatus has is due to being ceramic system(Sintering structure), therefore toughness it is low,
It is fragile.Thus, it is supposed that if previous mandrel made of ceramics is made to attenuate, there is the damaged worry to take place frequently such as broken and/or crackle.
The necessity for having replacement in the case of mandrel breakage becomes the reason of cost increases.This makes it difficult to keep previous mandrel thinner, no
The such hope of spinning speed high speed can fully be coped with.
Also, due to generating friction between fiber and mandrel, generate electrostatic.But since general ceramics are exhausted

Illustrate to generate spinning 15 to the twisting of fibre bundle 10 in the air flow spinning apparatus 5 of this implementation form referring next to Fig. 4
Appearance.In addition, indicating that the air in air flow spinning apparatus 5 flows with thick-line arrow in Fig. 4.
Fibre bundle 10 is made of plurality of fibers.The end for constituting the downstream side of each fiber of fibre bundle 10 is twisted and is twisted into
In certain root fibre bundle 10, but the end of upstream side becomes free end.It is imported from fiber entrance hole 34 each in air flow spinning apparatus 5
The free end of fiber flows to downstream side under the action of the air stream generated by the ejection air from air jetting nozzle 43.This
Sample passes through the upstream side end of fiber(Free end)Downstream side is flowed to, the direction overturning of the upstream side end, towards downstream side
(The downside of Fig. 4).The fiber of the state is known as to overturn fiber 10b.
A part in the fiber for including in fibre bundle 10 becomes continuous between fiber entrance hole 34 and fiber channel 39
State.The fiber of the state is known as core fibre 10a.
The free end of overturning fiber 10b is in turn room 41 by being flowed in the shape of a spiral around hollow guide shaft body 32
The influence of turn air-flow.Overturning fiber 10b is as shown in Figure 4 along the surface of the tapered portion 37 of hollow guide shaft body 32 at this as a result,
Surrounding's turn of tapered portion 37.Thus overturning fiber 10b is wound up into around core fibre 10a up successively.
Core fibre 10a is by the related twisting of overturning fiber 10b of turn.In this way, being wound up into core fibre by overturning fiber 10b
Core fibre 10a twisting is further given around 10a, above-mentioned overturning fiber 10b, which is twisted into core fibre 10a, generates spinning 15.
In addition, though the twirl of core fibre 10a will be to the upstream side(14 side of preliminary roller)It propagates, but the propagation is hindered by spicule 44
Only.In this way, spicule 44 has the function of preventing from twisting propagating.
It is wound since the spinning 15 generated in air flow spinning apparatus 5 is wound portion 8, which is paid under
Swim the carrying capacity of side.Spinning 15 and core fibre 10a are integrally downstream conveyed as a result,.Overturning on core fibre 10a
Fiber 10b slides into the fiber channel by related pulled from the inlet portion 40 of fiber channel 39 of core fibre 10a conveyed towards downstream side
39 inside.
As explained above, due to overturning fiber 10b dances around the tapered portion 37 of hollow guide shaft body 32
It is dynamic, therefore generate friction between the peripheral surface of tapered portion 37 and overturning fiber 10b.But the entire of tapered portion 37 is not it
Peripheral surface generates friction, close to the part of inlet portion 40 mainly in the peripheral surface of tapered portion 37(Fig. 5's is indicated with 37a
Part)Generate friction.
As previously described, because overturning fiber 10b from inlet portion 40(The upstream side end of hollow guide shaft body 32)Towing is slided
Into in fiber channel 39, therefore close to the part of inlet portion 40 in the internal face of the end face of the inlet portion 40 and fiber channel 39
(The part of Fig. 5 indicated with 39a)Generate strong friction.
Therefore, the part 37a, 40 and 39a of friction will be especially generated in the surface of hollow guide shaft body 32 between fiber
Collectively " fiber contacts portion "(The part of Fig. 5 indicated with thick line).
Then illustrate the feature structure in this implementation form.
The hollow guide shaft body 32 of this implementation form is characterized in that:Base part 50 with stainless steel, in the base material
The surface in portion 50 has been formed thinly coating(Superficial layer 51).Also, this implementation form is between base part 50 and superficial layer 51
It is formed with middle layer 52.The structuring concept of the hollow guide shaft body 32 of this implementation form is indicated in figure 6.
In the hollow guide shaft body 32 of this implementation form, superficial layer 51 is as by DLC(Diamond-like carbon)Envelope is constituted
Coating.Due to superficial layer 51(DLC envelopes)It is very thin, therefore most of base part by stainless steel of hollow guide shaft body 32
50 are constituted.Since there is stainless steel good electric conductivity, the hollow guide shaft body 32 of this implementation form to have good lead
Electrically.Therefore, the hollow guide shaft body 32 of this implementation form can easily bleed off the electrostatic that the friction with fiber generates.
In addition, keeping the downstream side body 33b of hollow guide shaft body 32 in order to bleed off the quiet of hollow guide shaft body 32
Electricity is by the material with good electric conductivity(Specially metal)It constitutes.Moreover, downstream side body 33b and composition spinning unit
2 metal framework electrical connection.The metal framework is grounded.
According to above structure, since hollow guide shaft body 32 is not easy to charge, the rubbish such as Soft flocks are not easy attached
On the surface for the hollow guide shaft body 32.As a result, due to can always maintain on the surface of hollow guide shaft body 32 clearly
Clean state, therefore the quality of the spinning 15 generated in air flow spinning apparatus 5 can be improved.Also, due to that can reduce in cleaning
The such labour safeguarded in surface of sky guiding axis body 32 and time, therefore the production efficiency of spinning unit 2 also improves.
The hollow guide shaft body 32 of this implementation form due to it is most of be the base part 50 of stainless steel, and it is previous
Ceramic system(Sintering structure)Hollow guide shaft body increased substantially compared to toughness.Thus, it is not easy to generate hollow guide shaft body
32 broken and/or crackle, can increase the degree of freedom of 32 shape of hollow guide shaft body.
For example, in hollow guide shaft body 132 previous shown in Fig. 7 A, if keeping the diameter of tapered portion 37 small,
Then the thickness in the direction orthogonal with the axis direction of hollow guide shaft body 132 is thinning.Previous hollow guide shaft body 132 is due to being
It is made of ceramics, so if thickness is thinning, easy to produce the breakages such as broken and/or crackle.Accordingly, it is difficult to make previous hollow
The diameter of guiding axis body 132 becomes smaller.The hollow guide shaft body 32 of this implementation form of this point due to having toughness appropriate,
Even if the diameter compared with the past for making tapered portion 37 becomes smaller as Fig. 7 B(Tapered portion 37 is set to attenuate)Thickness is thinning, is also not easy
Generate the breakages such as broken and/or crackle.In this way, the hollow guide shaft body 32 of this implementation form is compared with the past can to make tapered portion
37 diameter becomes smaller(Tapered portion 37 is set to attenuate).As a result, since the turn radius of fiber can be made to become smaller, air-flow can be made
The spinning speed of spinning apparatus 5 improves.
In the hollow guide shaft body 32 of this implementation form, it is formed with by DLC quilts on the surface of the base part 50 of stainless steel
The superficial layer 51 that film is constituted.As it is well known, DLC envelopes extreme hardness compared with stainless steel.Therefore by base material
The surface in portion 50 forms superficial layer 51(DLC envelopes), the wear resistance of hollow guide shaft body 32 can be increased substantially.
From the viewpoint of so that the wear resistance of hollow guide shaft body 32 is improved in this way, preferably at least in the portion of fiber contacts
Point(Fiber contacts portion shown in fig. 5)Form superficial layer 51.The hollow guide shaft body 32 of this implementation form is in the whole of base part 50
A peripheral surface(The circumferential surface of tapered portion 37 and cylindrical portion 38), it is close in the end face of inlet portion 40 and the internal face of fiber channel 39
The part of inlet portion 40(The part of Fig. 5 indicated with 39a)It is formed with superficial layer 51.Alternatively, it is also possible in entire fiber channel
Superficial layer 51 is formed on 39 inner surface.
Since DLC envelopes are noncrystalline, flatness rubs well low.Therefore, it is possible to reduce hollow guide shaft body 32 with
Overturn the friction between fiber 10b.Therefore, it is possible to make the overturning fiber 10b swimmingly turns around hollow guide shaft body 32,
The turn speed of overturning fiber 10b can be made to improve.In this way, according to the hollow guide shaft body 32, Neng Goujin of this implementation form
One step improves the spinning speed of air flow spinning apparatus 5.
As described above, according to the structure of this embodiment, hollow guide shaft body 32 has both wear resistance and toughness, friction is low
And it is conductive.As a result, compared with previous hollow guide shaft body made of ceramics, the turn speed of fiber can be made to carry
Height makes spinning speed improve.
The hollow guide shaft body of previous fine ceramics is white or the color close to white.Even if accordingly, there exist
Soft flocks(It is usually white)Equal rubbish are also difficult to find to ask as the rubbish in the case of being attached in hollow guide shaft body
Topic.
Since DLC envelopes are generally black, the hollow guide shaft body 32 of this implementation form of the DLC envelopes is implemented
Surface be black.Therefore, the energy in the case where the rubbish such as Soft flocks are attached in the hollow guide shaft body 32 of this implementation form
Enough easily find out the rubbish.As a result, can properly judge the necessity of the maintenances such as the cleaning of hollow guide shaft body 32.
Therefore, unnecessary maintenance will not be carried out, the production efficiency of spinning unit 2 can be improved.
As the method for forming above-mentioned DLC envelopes, well-known method appropriate can be utilized.But DLC envelope roots
There is conductive situation according to its forming method and there is no the case where electric conductivity.This is charged from hollow guide shaft body 32 is prevented
Viewpoint is set out, and preferably not only base part 50, superficial layer 51 are also conductive.Therefore, the hollow guide shaft of this implementation form
The superficial layer 51 of body 32 is as conductive DLC envelopes.Accordingly, due to 32 more difficult electrification of hollow guide shaft body, because
This can be effectively prevented rubbish and be attached on the surface of the hollow guide shaft body 32.
Then illustrate middle layer 52.
Since the hardness and the difference in hardness of DLC envelopes of stainless steel are very big, the close property of stainless steel and DLC envelopes
It is low.Thus, it is supposed that in the case where the surface of base part 50 directly forms DLC envelopes, there are the DLC envelopes to shell from base part 50
From worry.This implementation form is provided between base part 50 and superficial layer 51 for improving base part 50 and superficial layer 51
The middle layer 52 of close property.
As long as middle layer 52 has the hardness among the hardness of superficial layer 51 and the hardness of base part 50.Moreover,
Middle layer 52 is preferable if being constituted with gradually becoming highland multilayer from base part 50 to 51 hardness of superficial layer.This implementation shape
Middle layer 52 is made of thermal treatment layer 53, nitrogen treatment layer 54 and electroplated layer 55 successively from 50 side of base part in state.
Thermal treatment layer 53 is to apply the heat treatments such as quenching and tempering by the base part 50 to stainless steel to improve the base material
The part of the hardness on 50 surface of portion.
Nitrogen treatment layer 54 is that the surface of the base part 50 to implementing above-mentioned heat treatment has carried out well-known nitridation
The part of processing.Thereby, it is possible to further increase the hardness on 50 surface of base part.In addition, if by nitrogen treatment in base material
The surface in portion 50 forms compound layer, then due to the worry there are the compound layer from the sur-face peeling of base part 50,
If using the nitriding for not forming compound layer and only forming diffusion layer(Such as free radical nitriding)It is preferable.

It is not easy to be attached in the hollow guide shaft body 32.
In the hollow guide shaft body 32 of this implementation form, superficial layer 51 is arranged at the inlet portion 40 of fiber channel 39
On the part 39a of the close inlet portion 40 of 39 inner peripheral surface of fiber channel.
Since the fiber of turn is contacted with the above-mentioned position of hollow guide shaft body 32 in air flow spinning apparatus 5, lead to
Setting superficial layer 51 on the position is crossed, the wear resistance of hollow guide shaft body 32 can be improved.
In the hollow guide shaft body 32 of this implementation form, base part 50 is made of stainless steel.
The base part 50 for constituting hollow guide shaft body 32 with conductive material in this way, can certainly bleed off
The electrostatic that the friction of hollow guide shaft body 32 and fiber generates.
In the hollow guide shaft body 32 of this implementation form, being provided between superficial layer 51 and base part 50 makes superficial layer
51 and the middle layer 52 be close to of base part 50.
Superficial layer 51 is not easy to remove from base part 50 as a result, and the durability of hollow guide shaft body 32 improves.
In the hollow guide shaft body 32 of this implementation form, superficial layer 51 is black.
It is black, the rubbish such as the Soft flocks of observation attachment on a surface to make the surface of hollow guide shaft body 32 in this way
It becomes easy.Accordingly, the cleaning for carrying out hollow guide shaft body 32 is become easy when maintenance etc..
The turn room 41 that the air flow spinning apparatus 5 of this implementation form has hollow guide shaft body 32, is formed with fiber twist
Nozzle assembly 31 and by fiber guide to the spicule 44 in turn room 41.
The air flow spinning apparatus 5 compared with the past can improve spinning as a result of above-mentioned hollow guide shaft body 32
Yarn speed.
The spinning frame 1 of this implementation form has said flow spinning apparatus 5 and winds the spinning that the air flow spinning apparatus 5 generates
Yarn 15 forms the winder 8 of package 18.
The spinning frame 1 is as a result of said flow spinning apparatus 5, therefore the life compared with the past that can improve package 18
At speed.
Although the preferred implementation form of the present invention is explained above, above structure can be changed for example as follows.
The material of base part is not limited to stainless steel, as long as having the material of good electric conductivity.As
Such material can also enumerate such as iron, conductive ceramic or superhard alloy in addition to stainless steel(Tungsten carbide etc.)Deng.But
It is that, with corrosion resistance and on this point of having toughness appropriate, it is not that base part 50 is made as above-mentioned implementation form
The steel that becomes rusty is preferable.
In above-mentioned implementation form superficial layer 51 is formed in the entire peripheral surface of base part 50(DLC envelopes).As a result,
The whole wear resistance of hollow guide shaft body 32 can be improved.But from preventing base part 50 from being ground with caused by the contact of fiber
It damages this viewpoint to set out, superficial layer 51 have to be not necessarily set in the entire peripheral surface of base part 50, as long as at least in fibre
Tie up the part contacted with base part 50(Fiber contacts portion 37a, 40 and 39a shown in fig. 5)Form superficial layer 51.Due to
General DLC envelopes high price, so if only if above-mentioned fiber contacts portion forms superficial layer 51, then it is hollow it is possible to realize reducing
Guide the manufacturing cost of axis body 32.
Due to the layer that middle layer 52 is the close property for improving base part 50 and superficial layer 51, base part 50 with
Middle layer 52 can also be omitted in the case that close property between superficial layer 51 is enough.
Superficial layer 51 is not limited to DLC envelopes, as long as the layer harder than base part 50.Such as it is shown in fig. 6
Middle layer 52(Electroplated layer 55, nitrogen treatment layer 54 and thermal treatment layer 53)All than base part 50(Stainless steel)Firmly.Therefore, for example
In the case of the DLC envelopes that Fig. 6 is omitted, electroplated layer 55 can be grasped as superficial layer.
Equally, in the case where omitting DLC envelopes and electroplated layer 55 of Fig. 6, nitrogen treatment layer 54 can be regard as surface
Layer is grasped.In addition, due to nitrogen treatment layer 54 compared with DLC envelopes difference of hardness, cannot say that wear resistance is enough.Therefore,
In the case where it is nitrogen treatment layer 54 to make superficial layer, there is the possibility worn due to the friction hollow guide shaft body 32 with fiber
Property.But in the case where it is nitrogen treatment layer 54 to make superficial layer, since the DLC envelopes of high price are omitted, having can
Inexpensively constitute the such advantage of hollow guide shaft body 32.Therefore, worn out in the hollow guide shaft body 32, even if
Burden in terms of 32 cost of hollow guide shaft body more renewed also very little.
Spicule 44 can also be omitted.In this case, 10 side of fibre bundle is formed in fiber guide component 30
