Description
Technical field
The present invention relates to a kind of draft mechanism for weaving loom, which is fed into draft mechanism for pulling
Linear fiber beam.
Further it is proposed that a kind of weaving loom, is preferably implemented as sir jet spinning machines.
Background technique
Type regardless of weaving loom, the draft mechanism for weaving loom are used to for the fineness of linear fiber beam being set as
(for example, by the available combing sliver of carding machine or concurrently run to multiple combing slivers in draft mechanism) expectation
Value.For this purpose, draft mechanism includes multiple roller arrangements, the multiple roller arrangement connects on the direction of transfer of the fibre bundle of feeding
It arranges continuously, and each of the multiple roller arrangement includes two or more draw rolls again.
Under any circumstance, be constantly present the draw roll in roller and opposite roll form, central roll may in " loaded " position and
Move back and forth between releasing position.The roll body of roller and corresponding opposed roller against each other so as in " loaded " position in a clamped manner
Fibre bundle is guided, roller can take the position in releasing position, and in the position, the roll body of roller and corresponding opposed roller does not connect
Touching.Therefore, in the release position, roller can be far from the mobile distance of opposed roller, so that their roll body does not contact, and fibre bundle
It may be inserted between roller and opposed roller or removed from it.
In the prior art, typically now the roller of all roller arrangements is supported in the common bracket for support arm form.
Support arm is attached to base portion bracket again, and opposed roller is supported on the base portion bracket and can rotate relative to it.If now
All rollers will be promoted to leave opposed roller, then support arm need to only rotate around the axis of rotation.For example, in 1710058 A1 of DE
In describe this draft mechanism.
Even if this solution is seemingly practical at first view because all rollers all can by single it is mobile be elevated from
Their corresponding opposed rollers are opened, all rollers are supported on to the supporting walls being supported on only one side by means of rotary joint
On have also the drawback that.Particularly, the pivotal point of support arm is not optimal at different distances with each roller, because each roller fills
Therefore the force flow between roller and opposed roller set is different.
Summary of the invention
Therefore, the purpose of the present invention is to propose a kind of draft mechanism and equipped with the weaving loom of the draft mechanism, eliminate
The shortcomings that drawn.
The purpose is realized by the draft mechanism and weaving loom of the feature with independent claims.
According to the present invention, for pulling the draft mechanism for weaving loom for being fed into the linear fiber beam of draft mechanism
It is characterized in that comprising at least two draft mechanism modules continuously arranged on the direction of transfer of fibre bundle.It is each individual
Draft mechanism module includes roller and the opposed roller corresponding to roller (it is understood that multiple rollers may be present for each draft mechanism module
Or opposed roller), wherein the roller and opposed roller of each draft mechanism module have the roll body that can be rotated around the axis of rotation.For example, roller
Body is cylindrical plastic body (it can have multiple layers) or the metal cylinder with corrugated surface.In addition, one or more rollers
And/or opposed roller can be with ribbon toroid around as be known in the art.Other than guiding piece, corresponding band can also be via
Corresponding roller or opposed roller are guided using one or more additional induction elements.
Under any circumstance, fibre bundle can be guided between roller and the roll body of corresponding opposed roller in a clamped manner.One
Denier fibre bundle is located between the roller and opposed roller of two adjacent draft mechanism modules, when the sender in fibre bundle looks up into
The first draft mechanism module draw roll (=roller and opposed roller) than the draw roll of the second draft mechanism module rotation it is slower when,
Pull fibre bundle.This leads to the drawing of the fiber of fibre bundle desired parallelization and fibre bundle.Finally, if according further to fibre
The quality of beam or the rotation speed for adjusting one or more draw rolls based on the fluctuation of length of thickness are tieed up, then finally can also be sent out
The homogenization of raw fibre bundle.
Now, it is a feature of the present invention that each draft mechanism module includes individual bracket, roller and opposed roller are supported
On the individual bracket.It therefore, compared with prior art, is no longer all rollers or all opposed rollers all with above-mentioned support
The form of arm is supported on the situation in common bracket.More precisely, draft mechanism is divided into multiple draft mechanism modules, often
A draft mechanism module includes individual bracket, wherein only the roller and opposed roller of the draft mechanism module are supported on each support
On frame.The support occurs via the rotary shaft of corresponding draw roll herein, and the rotary shaft of corresponding draw roll can be revolved
It is supported in the ball or roller bearing of such as bracket with turning.
Furthermore, it is specified that the roller of draft mechanism module is supported on the bracket of corresponding draft mechanism module via receptacle
On, so that it can move back and forth between " loaded " position and releasing position independently of the roller of other draft mechanism modules.Therefore,
One or more rollers of draft mechanism module can independently of other draft mechanism modules one or more rollers from it or they
Corresponding opposed roller promoted.Therefore, the roll body of roller and corresponding opposed roller in " loaded " position against each other, so as to clamp
Mode guides fibre bundle.In addition, they can be moved away from each other in resting position, so that they will not be contacted.
In other words, each draft mechanism module is therefore independent of one another, so that roller and opposed roller in draft mechanism module
Between force flow independently of the corresponding force flow in other draft mechanism modules.If the dress by being described more fully below now
It carries element and presses the roller of draft mechanism module in its " loaded " position against corresponding opposed roller, then due to dividing draft mechanism
From at each draft mechanism module, the guidance of fibre bundle is independently of the guidance in other draft mechanism modules.Moreover, for each
Draft mechanism module can individually adjust the holding power on each roller for acting on draft mechanism module, because of draft mechanism module
Roller load and/or the mobile roller that never will affect remaining draft mechanism module load and/or movement.
By the way, in this regard it is noted that certainly, draft mechanism connects in the state that it is mounted in weaving loom
One or more driving devices are connected to, so as to carry out the drawing of above-mentioned fibre bundle.
Particularly advantageously, if draft mechanism includes guide rail, the bracket of at least one draft mechanism module can be by means of
Fixed device is fixed to the guide rail.Therefore, bracket is guided on guide rail and can be opposite in the releasing position of fixed device
It is mobile in guide rail, preferably move in a linear fashion.Moving direction should may be in one direction (and preferably only at this
On direction), the direction corresponds to the predetermined direction of transfer of the fibre bundle in draft mechanism.Pass through one or two mobile drafting machine
Structure module can be easily adjusted the mutual spacing between two adjacent draft mechanism modules, using it is generally necessary to according to wait lead
To adjust spacing, (distance must always at least correspond to the length of the longest fiber of fibre bundle to the fibre bundle of drawing, to ensure fibre
Dimension is primary always to be clamped by the draw roll of a draft mechanism module；Otherwise, fiber will between two draft mechanism modules quilt
Tearing).
Once having set required spacing and/or corresponding draft mechanism module relative to guide rail positioned at required
At position, fixed device just be can be moved into during fixed bit sets, and in the fixation position, corresponding draft mechanism module is relative to leading
Rail is fixed.In principle, fixed device can be any device, and using the device, corresponding draft mechanism module, which can be fixed on, to be led
Appropriate location on rail.Preferably, at least one screw or a fixing bolt are used for each fixed device.
Although it have been described that be used for draft mechanism module displaceable property, but if draft mechanism it is several (preferably
Ground is all) draft mechanism module is appropriately supported on guide rail then will readily appreciate that (preferably on identical guide rail)
It is advantageous.In this case, guide rail can move together with corresponding draft mechanism module from the weaving loom with draft mechanism
It removes.This has the advantages that conclusive, i.e., before guide rail and draft mechanism module reinsert weaving loom, can adjust outside weaving loom
The mutual distance of each draft mechanism module in portion.
It is equally also very advantageous to, if being operably connected to one or more draft mechanism modules of guide rail with shape
The mode of shape cooperation connects guide rail.For example, guide rail can have one or more recessed portions, one of corresponding draft mechanism module
Or multiple extensions engaged in the one or more recessed portion (or vice versa).Extension and/or recessed portion can have one
A or multiple undercutting and e.g. swallow-tail form, so that draft mechanism module can only be shifted relative to guide rail, but cannot revolve
Turn.Therefore, other than mutual spacing, it is fixed for being connected to the mutual alignment of all draft mechanism modules of guide rail.This is anti-
Only there is operating mistake during adjusting draft mechanism.Recessed portion and extension will likely be also implemented so that at fixed device
When its releasing position, the draft mechanism module for being connected to guide rail can remove independently of one another from guide rail (preferably to be taken upwards
Under).Each draft mechanism module can be easy to quickly replaced in this way, without removing other drawing-offs from draft mechanism
Mechanism module or guide rail.In this case, recessed portion and/or extension can have rectangular or square section.Preferably, this
A little parts are without undercutting to allow above-mentioned lift off.
It is also advantageous that if draft mechanism includes the draft mechanism module of at least two similar constructions.Which reduce
Expense relevant to design, maintenance, adjustment and maintenance；Cost can minimize.Preferably, all draft mechanism modules have similar
Construction, although similitude is not necessarily related to roll body.The type and/or size of each draw roll can each draft mechanism module it
Between change.
Advantageously, if roller and/or opposed roller have a rotary shaft, which is supported within the carrier or on bracket only
On only one side.In this case, roll body is located at the side of respective brackets, so that fibre bundle is not contacted with bracket.Especially
Ground, each rotary shaft should be supported in the trunnion bearing of bracket.Furthermore it is advantageous that if rotary shaft is from corresponding roller
Body extends through bracket and protrudes on the side of roll body from bracket in bracket.For example, driving device (such as transmission belt
Or gear) final engageable on outburst area, to enable corresponding draw roll rotatably to move.
It is also advantageous that if at least bracket of a draft mechanism module includes the first bracket segment and the second bracket
Segment, it means that bracket is further divided into two regions.Therefore, roller and opposed roller may be propped up by means of different bracket segments
Support.In this case, the roller (or multiple rollers) of corresponding draft mechanism module be supported on so-called first bracket segment and
On the opposed roller of draft mechanism module on so-called second bracket segment, wherein the first bracket segment and the second bracket segment are made
For the presence of individual component.Two bracket segments may be the same or different.Under any circumstance, it is likely to the first bracket section of adjustment
Position of the section relative to the second bracket segment, and therefore adjust the relative position of roller and opposed roller.This finally can also be used to set
Fixed roll whether on the predetermined direction of transfer of fibre bundle positioned at opposed roller slightly forward, side or surface later；Adjustment influences to lead
It draws as a result, being selected according to fibre bundle.Preferably, the first bracket segment and the second bracket segment of draft mechanism module
Direct interconnection is in direct contact with one another.
Particularly advantageously, if the first bracket segment has for the second bracket segment to be supported on the first bracket segment
On guiding piece, and/or if the second bracket segment have for the first bracket segment to be supported on the second bracket segment
Guiding piece.Preferably, corresponding guiding piece is oriented such that the bracket segment of draft mechanism module only can be in the transmission direction
It is displaced relative to each other.On the other hand, it should the movement in the axial direction of rotary shaft is prevented by guiding piece.
Equally it is very advantageous that if the first bracket segment can be fixed relative to the second bracket segment and/or the second support
Frame segment can be fixed by means of at least one fixing element relative to the first bracket segment.Fixing element can be screw or spiral shell
Nail/nut combination, lock or other devices, the relative position of the first bracket segment Yu the second bracket segment can be fixed using it.Such as
Korean pine opens fixing element (each draft mechanism module can also have several fixing elements), then the first bracket segment and the second bracket section
Section can be moved relative to each other, and preferably only be moved, to enable the position of draw roll to be adjusted relative to each other.
It is therefore advantageous that if at least one fixing element can move between fixed position and releasing position, wherein
When at least one fixing element is in its releasing position, the first bracket segment and the second bracket segment can be moved relative to each other
Position, and wherein when at least one fixing element, which is in it, fixes in position, the first bracket segment is relative to the second bracket section
Section is fixed and/or the second bracket segment is fixed by means of at least one fixing element relative to the first bracket segment.This leads
It causes that opposed roller of the roller relative to identical draft mechanism module may be adjusted independently of the draw roll of remaining draft mechanism module
Position.
It is also advantageous that if the first bracket segment and the second bracket segment are on being supported on the first bracket segment
It contacts with each other in the " loaded " position of roller and in releasing position.Preferably, the first bracket segment is in the release position relative to second
Bracket segment has and position identical in " loaded " position.In other words: consolidating as long as fixed device be in its (or they)
Positioning is set, and the first bracket segment of draft mechanism module and the mutual alignment of the second bracket segment are always to maintain identical.Preferably,
When the draft mechanism from side, the first bracket segment and the second bracket segment form C-shaped.
It is also advantageous that if at least one draft mechanism module includes loading member, the loading member and drafting machine
The roller of structure module is associated, and by means of the loading member, the holding power of restriction can be applied to roller in " loaded " position.Load member
Part would be preferably attached to bracket segment, and roller is supported on bracket segment.Preferably, loading member does not act directly on the rotation of roller
In shaft.Instead, loading member should be contacted with receptacle (rotary shaft is supported on wherein), so as in receptacle
Applied force.Loading member can be pneumatic linear actuator, air spring or stick cylinder.
In particular it is advantageous that for example, if at least one loading member (preferably all loading members) includes can
The pressure elements of displacement ground support, wherein pressure elements is embodied by elastic pressure diaphragm or is connected to elastic pressure diaphragm,
Wherein pressure diaphragm defines pressure chamber, can apply pressure in the pressure chamber by means of compressed air source.Pressure membrane is preferably
Plane or arch and elastic construction (such as being made of rubber or rubber composition).If (it can be partly by pressure for pressure chamber
Diaphragm is limited and is partly limited by corresponding shell) it is pressurized, then pressure diaphragm outwardly protrudes, or attempts correspondingly convex
(wherein by introducing compressed air into pressure chamber, there may be pressure) out.
Therefore, roller is loaded mainly by means of compressed air, and compressed air can be empty by the compression of corresponding cotton mill
The compressor of gas network or the weaving loom with draft mechanism provides.It is resided in the fact that using the advantages of corresponding diaphragm,
It i.e. when it is moved due to pressure, does not need to overcome static friction, because the component of phase mutual friction is not present.More precisely, only
Need to change the shape of diaphragm to load roller, this is for example realized by introducing compressed air into pressure chamber.In this feelings
Under condition, in the case where no jerking movement load change, the variation of accurate, reproducible holding power or holding power is possible.
In contrast, in cylinder/piston solution known in the prior art, the mobile suction of jerking movement always occurs when the load is varied
It receives, because before the relative movement in the case where sliding friction is only used only between two elements is possible, it is necessary to first
Overcome the static friction between cylinder and piston.
In this case, it if receptacle is implemented as swingle, has the advantage that.Swingle preferably has U-shaped
Shape.Swingle can be supported on bracket via two supporting legs of U-shaped, and in this case, rotary shaft should be supported on
In the region of the base portion of the U-shaped of connection leg (for this purpose, base portion preferably has drilling, wherein there are swivel bearing, roller
Rotary shaft is supported in the swivel bearing).
Weaving loom according to the present invention has according to draft mechanism described above or below, especially for draft mechanism
May with any combination have any and all features, if the feature mentioned in claim 1 be implemented and be
In the range of there is not technical contradiction.
Weaving loom is preferably used for producing the sir jet spinning machines of yarn from fibre bundle, and wherein sir jet spinning machines includes having
At least one spinning jet nozzle of minor air cell.Minor air cell also has the entrance for entering fibre bundle.In addition, spinning jet nozzle includes yarn
Line forms element, which forms element and extend at least partly into the minor air cell with entrance opening, wherein in main shaft
Annular gap is formed between outer surface and the inner wall of the minor air cell towards main shaft.Spinning jet nozzle has air nozzle, and air can lead to
It crosses air nozzle to be introduced into minor air cell, be rotated to apply in the entrance opening region of main shaft to fibre bundle.Finally, main shaft has
There is internal extraction channel, yarn can extract channel out by the inside and be pulled from minor air cell.
The weaving loom for being preferably implemented as sir jet spinning machines is accordingly used in producing yarn by elongate fibers.By means of by
The swirling eddy that the indoor air nozzle of vortex in the entrance area that yarn forms element generates, the outer fiber of fibre bundle twine
It is wound on around interior core fibre, and to form winding fiber important for required yarn strength.For example, this is generated
With the yarn really twisted, which is finally discharged via extraction channel from minor air cell, and can be wound on pipe.
In general, term " yarn " is for the present invention for meaning fibre bundle, and wherein at least part of fiber twines
It is wound on inner core.Therefore also include the yarn on conventional meaning, such as fabric can be processed by means of loom.
However, weaving loom can also be realized as sir jet spinning machines, by means of the sir jet spinning machines can manufacture so-called rove (
Referred to as slubbing).Such yarn is characterized in that, is enough for yarn to be transmitted to subsequent weaving loom although it has
Certain level intensity, but it is still that can pull.Therefore, rove can be thick by means of processing before it is finally woven
The drafting system (for example, draft mechanism) of the weaving loom of yarn is pulled.
Alternatively, weaving loom according to the present invention can also be realized as the sir jet spinning machines of draft mechanism form or also real
It is now ring spinner.
Finally it is advantageous that if draft mechanism has above-mentioned guide rail, wherein each draft mechanism module is fastened to and leads
Rail.In this case, the draft mechanism module and guide rail for being operably connected to guide rail form unit, which can unclamp
It is removed as a whole from weaving loom after one or more clamp devices (for example, screw or locking member) of weaving loom.
This has greatly helped the setting (seeing above) of each distance, because can be adjusted outside weaving loom.
