Description
Technical field
The present invention relates to a kind of reciprocating apparatus of the drafter for textile machinery, for realizing at least one compound fibre
The reciprocating motion of dimension.Reciprocating apparatus has along drafter extension and mobilizable track.At least one induction element can
Moved by the track, for guiding composite fibre by drafter and composite fibre is moved back and forth.Track is herein
It can be moved by driver along its longitudinal direction, therefore track can be placed oneself in the midst of among reciprocating motion.In addition, the present invention also relates to
A kind of and method for running this reciprocating apparatus.
Background technology
The reciprocating apparatus of a kind of drafter for textile machinery as known to the A1 of DE 10 2,008 064 531.This is past
Apparatus for coating, which includes, to be used for element that reciprocating apparatus is coupled on track and for being coupled to the connection on the compression unit
Arm, the track is parallel with drafter roll and can elapse.The shortcomings that this reciprocating apparatus is, the track be difficult along
Drafter elapses.I.e. track extends along whole drafter, therefore the length of track is likely to be breached up to tens meters.Track
Herein with certain spacing supporting within the bearing.Therefore track is made to be difficult to be elapsed along drafter.By track within the bearing
Friction, track is difficult or may not be entered by bearing spigot.
In addition, bending moment is applied on track by the linking arm of the compression unit, it passes through compression unit and drawing-off
The frictional force of mechanism roll（It is produced by corresponding frictional resistance）Produce,（Track and linking arm mutually have straight mostly
Angle）.Because being provided with the multiple compression units being generally arranged on track, multiple bending moments correspondingly act in orbit.
The two effects（Friction in bearing and single bending moment）Prevent track from elapsing again.The two effects can also guide rail
The bending in road.The frictional resistance of track within the bearing can cause resistance, and the therefore caused bending on bearing.Equally, it is in-orbit
Road is provided with the position of linking arm, and bending moment can also cause bending.Therefore so-called drawer effect, its middle orbit occurs
Crimping within the bearing.If the track of crimping unclamps within the bearing, the setback of track and compression unit can be caused, this
It is very not by desired.Therefore track can not controllably be elapsed.
The content of the invention
Therefore the object of the present invention is to illustrate a kind of reciprocating apparatus for eliminating disadvantages mentioned above.
This purpose is achieved by the reciprocating apparatus and its operation method of the feature with independent Patent right requirement.
A kind of reciprocating apparatus of the drafter for textile machinery is illustrated, for realizing at least one composite fibre
Move back and forth.Mobilizable track extends along drafter, at least one to be arranged on by the moveable induction element of track
On this track, so that composite fibre is moved back and forth by drafter.Track herein can also be vertical along it by driver
Moved to direction, therefore track can be placed oneself in the midst of among reciprocating motion.
Composite fibre is guided by the induction element by subsidiary drafter roll.Induction element can for this
Such as inserted with guide recess, composite fibre in this guide recess.The induction element can also include compression unit, and it is to multiple
Condensating fiber is compressed.The advantages of composite fibre moves back and forth is that it is not continuously on identical position in drafter
Passed through between roll.Therefore, cutting of the composite fibre in these drafter rolls is avoided.Pass through the reciprocal of composite fibre
Motion, the drafter roll equably bearing load on wider region, therefore avoid the cutting on a position, and
With the service life for extending drafter roll.
Reciprocating motion is moved back and forth herein, and it is delivered on induction element by track, therefore composite fibre is in drawing-off
Elapsed back and forth in the region of mechanism roll.Reciprocating stroke can be for example also referred to as by moving back and forth.Driver produces track herein
Move back and forth, move back and forth or reciprocating stroke.
By the present invention, reciprocating apparatus includes at least one power-boost driving device, and it assists the past of the track by tractive force
Multiple motion.Power-boost driving device can be acted on for example in orbit so that it loads tractive force to track.By tractive force along leading
Stretch mechanism and the track is pulled by bearing.Therefore bending of the track on bearing is avoided, therefore avoids above-mentioned drawer
Effect.Therefore track can move along drafter by definition.Power-boost driving device also can be advantageously existing
It is installed on weaving loom on reciprocating apparatus.
Additionally or alternatively, power-boost driving device can give track on-load pressure, so that track elapses along drafter.
If compared with acting on friction sum in orbit, power-boost driving device pulls more or less, then drives
Device loading level is different.If power-boost driving device pulls excessively, driver stops, if power-boost driving device pulling is very few,
Driver helps to realize componental movement, and extraly elapses.If power-boost driving device as required as the crow flies by
Pull, so as to moving track, then make driver fully relaxed, and only preset the direction of motion.
If only applying power-boost driving device, it is preferably provided with the end that the relative with driver of this machine is put.
If track then moves towards power-boost driving device, power-boost driving device is pulled, track moves towards driver, and pulls driver,
Power-boost driving device can then be disconnected.Because the motion of track needs high tractive force, and driver is not for this load mostly
Design or size it is inadequate, so using two power-boost driving devices when uncertain.So the two power-boost driving devices are set
In two rail ends of track, so as to which track alternately is pulled into oneself, wherein the power-assisted of non-straight pulling can be closed
Driver.
Here, if driver is also towards moving left track, power-boost driving device is towards Zola's dynamic rail road, if driver is towards the right side
Moving track, then towards right pulling track.
The scheme that is advantageously improved of the present invention is that the driver is arranged in the region of the rail end.Therefore, should
Driver can simply form, because driver need to only have the interface position for track.Additionally or alternatively, at least
One power-boost driving device is arranged in the region of rail end.Therefore, as driver, power-boost driving device also can be simply
Form.In addition to realize maintenance purpose, driver and/or power-boost driving device can be reconstructed or changed especially suitablely.Driver
And/or power-boost driving device need not necessarily need to be provided in outmost rail end herein.Driver and/or power-boost driving device also being capable of courts
Outmost rail end has spacing.
Due to position reason, power-boost driving device may not be accurately provided in machine beginning and machine end.At this
In the case of kind, power-boost driving device is arranged near machine beginning and machine end, and tolerates the smaller odd in track
Also suffer passage.
As well as profit, power-boost driving device is respectively arranged with the region of the two rail ends, by its energy
It is enough to load tractive force to the track.Here, the two power-boost driving devices alternately can load tractive force to track, therefore will
Track pulls to another power-boost driving device from a power-boost driving device.Therefore, track is pulled by bearing, so as to avoid track
Bending.
In addition it is further advantageous that to the track load the tractive force of at least one power-boost driving device with
The motion of the driver is to be coupled, therefore can be preset by the power-boost driving device to institute by the driver
State the tractive force loading of track progress.Therefore driver has preset rhythm, and power-boost driving device draws track by this rhythm
To oneself.Driver serves metronomic at this, and its own for example no longer triggers reciprocal fortune by tractive force and/or pressure
It is dynamic.Here, two power-boost driving devices can be also set in the region of rail end.Therefore driver has preset rhythm,
Track is alternately pulled to oneself by two power-boost driving devices by this rhythm.
It is further advantageous that described two power-boost driving devices formed in two regions of the rail end it is described past
Multiple motion, wherein the driver is so controlled, that is, make it that the driver is powerless.Here, driver is both without traction
Also no pressure effect is in orbit for power, has simply preset the motion of track.That is so that the two power-boost driving devices simply trigger
Move back and forth, wherein track is alternately pulled to oneself by the two power-boost driving devices respectively.
As well as profit, at least one power-boost driving device is arranged between the two rail ends.If driver
It is arranged on power-boost driving device in rail end, then since the certain length of track, the driver and power-boost driving device
It is not enough to realize the reciprocating motion of track.Such as extra power-boost driving device can be arranged on the centre between rail end, with
Just from the middle reciprocating motion for assisting track.
It is further advantageous that the power-boost driving device includes flexible member, pneumatic cylinder, hydraulic cylinder and/or electric linear
Driver, it is to track loading tractive force and/or pressure.Flexible member is, for example, that a kind of cost of power-boost driving device is cheap
Deformation program because do not need energy supply interface.By pneumatically or hydraulically cylinder, higher traction can be loaded to track
Power or pressure.The electromotion linearity driver can be accurately controlled.
In addition, being advantageously improved in scheme in the present invention, the driver and/or the power-boost driving device by means of
The rocking bar effect of lever dot point is in orbit.Therefore lever law is pressed, can strengthens and trigger reciprocating power.
It is further advantageous that being provided with step-like disk in the drive shaft of driver, it has at least two bands different
The section of radius.Here, the section of the step-like disk can be identified by sensor, therefore it can recognize that the driving
The state of device.Sensor for example can be grating sensor herein, and it is interrupted by two sections of step-like disk or right and wrong
Interrupt.The grating sensor can be arranged in the fringe region of step-like disk for this, therefore the section meeting with relatively large radius
This grating sensor is interrupted, or the region with small radii will not interrupt the grating sensor.Therefore can be with simple
Mode determines which kind of state driver has.This point is important, to infer the motion conditions of errant and/or state.
Additionally or alternatively, the direction of rotation of driver can be also understood by sensor and step-like disk.Therefore it is outstanding
It can understand, and track moves in which direction.Therefore according to the direction of motion of track, the driver can correspondingly be controlled
And/or at least one power-boost driving device.
But by step-like disk and sensor, the state of driver is also can determine after textile machinery restarting,
And the it is thus determined that position of track.Driver for example rotates in an arbitrary manner for this, until identifying that section converts.In section
During change, the current state of driver can be also understood, and be therefore also aware that the position of track.Therefore driver is associated
.
Checked and accepted by the step-like disk operated by driver, track is pulled from which side.Even if machine is temporarily closed
Close, can also understand the position of track at any time by this step-like disk.It additionally therefore can recognize that, move back and forth along which
Direction carries out and must be pulled along which direction, which power-boost driving device in this or another machine side correspondingly plus
Carry.
It is also advantageous that the driver is mutually coordinated consistent with the motion of at least one power-boost driving device.
It is particularly advantageous that at least one power-boost driving device consumes all tractive force being applied on the track
And/or at least the 75% of pressure.But at least one power-boost driving device, which can consume, all is applied to leading on the track
At least the 90% of gravitation and/or pressure.
In the special improvement project of the present invention, driver and/or power-boost driving device include buffer element, therefore described
Track is buffered in reciprocating motion along its longitudinal direction.Also can be in the turning point region of motion here, moving back and forth
It is buffered.Therefore unexpected reciprocating motion can be prevented.
It is further advantageous that the track is moved with the reciprocating motion speed between 0.5cm/s and 5cm.To realize
The reciprocating motion of composite fibre, relatively small reciprocating motion speed is reached, to avoid the cutting in drafter roll.It is logical
Relatively low reciprocating motion speed is crossed, driver and/or power-boost driving device need not be particularly effective rate.Higher reciprocating motion speed can
Higher reciprocating motion acceleration can be also required to, therefore driver and/or power-boost driving device equally must be more efficiently.
In addition it is further advantageous that moving back and forth the amplitude of oscillation also having for example between 0.3cm and 15cm.But the amplitude of oscillation
Also can be 0.3 to 5cm.But the amplitude of oscillation also can be between 4 and 10mm.Therefore, it is possible to select drafter roll by
Carry region.When the amplitude of oscillation is smaller, the smaller area of drafter roll is only loaded, and when the amplitude of oscillation is larger, is correspondingly loaded
Large area.
In addition a kind of method for running reciprocating apparatus is also proposed, it presses one or more of front and back specification
Individual feature is formed.Reciprocating apparatus especially has track, and it extends along drafter and in its axial direction along drafting machine
Structure may move.At least one induction element is provided with orbit, and it realizes compound by the motion of track by drafter
The reciprocating motion of fiber.Track is moved by driver along its longitudinal direction herein, therefore track is placed oneself in the midst of among reciprocating motion.
By the present invention, track loads tractive force by least one power-boost driving device.Therefore track is pulled by bearing, so as to
Bending is avoided from the beginning.
The scheme that is advantageously improved of the present invention is that the power-boost driving device and/or the driver load to the track
Tractive force, its equivalent to it is all being applied on the track and cause the reciprocating power at least 75%, especially extremely
Few 90%.Therefore compared with promotion, track is more strongly pulled by bearing, so as to avoid bending of the track on bearing.
Another advantageous embodiment of the present invention is that the power-boost driving device and/or the driver give the track
Tractive force is loaded, it is equivalent to all being applied on the track and cause the 100% of the reciprocating power.Therefore,
Track pulls always by bearing, so as to avoid the bending of track.
It is further advantageous that driver and/or power-boost driving device are arranged in a rail end of track, driver and/or
Power-boost driving device is arranged in another rail end.When arriving at the reciprocating turning point of the track, institute is disconnected
State the driver stretched and/or the power-boost driving device.Simultaneously and/or then, the driver and/or the power-boost driving device
Connected in the rail end that the corresponding of the track is put, so as to give track loading tractive force.Therefore can always draw
Dynamic rail road, so as to avoid bending.Track is always alternately pulled by the driver and/or power-boost driving device of rail end herein.
Additionally or alternatively, the driver of two rail ends of track and/or power-boost driving device add to track simultaneously
Carry tractive force.Therefore driver and/or power-boost driving device can give the rail end of track to load the tractive force of 110 newton.Separately
Driver and/or power-boost driving device in one rail end can load the tractive force of 10 newton to track.Track is then along track
The direction movement of end, the power of 110 newton is applied in this rail end by driver and/or power-boost driving device.100 newton's
Effective force comes into force herein.Reaction force is used for reducing herein the gap of driver and/or power-boost driving device.It is noted here that numerical value
110 newton and 10 newton are example herein, to facilitate displaying.The ratio and/or absolute value of the two power also can it is bigger or
It is smaller.

Embodiment
Fig. 1 shows a part for reciprocating apparatus 1, and it has track 3, driver 5, multiple induction element 4a-4c.It is this
Reciprocating apparatus 1 is, for example, prior art, and is a part for unshowned drafter herein.The drafter includes multiple
Drafter roll, they carry out drawing-off to composite fibre 2a-2f.The drafter is extended parallel to track 3 herein.
Driver 5 performs local rotary motion Db in this embodiment, and it makes track 3 place oneself in the midst of among reciprocating motion.
Rotary motion Db is delivered on track 3 by driver 5 by articulated coupling 16.The driver 5 is arranged on the track 3 herein
On rail end 7a.It is to move back and forth to move back and forth Cb, or also referred to as reciprocating stroke.Track 3 is supported on bearing 9a, 9b herein
In.
In addition three linking arm 8a-8c are provided with the track 3, and they are delivered to subsidiary guiding element by Cb is moved back and forth
On part 4a-4c.Induction element 4a-4c guides two composite fibre 2a-2f respectively.Induction element 4a-4c is also able to have
There is unshowned compression unit herein, they are compressed to composite fibre 2a-2f.Induction element 4a-4c is additionally arranged at herein
Between unshowned drafter roll.In addition, move back and forth Cb is delivered to composite fibre 2a-2f by induction element 4a-4c
On.
The advantages of composite fibre 2a-2f is moved back and forth is that they are not in drafter roll on only one position
Between pass through.Composite fibre 2a-2f is guided back and forth by moving back and forth in the broader region between drafter roll.Therefore
Drafter roll is equably loaded by composite fibre 2a-2f, and prevent cut on the position of drafter roll it is each multiple
Condensating fiber 2a-2f.
As previously noted, Fig. 1 merely illustrates a part for reciprocating apparatus 1.Reciprocating apparatus 1 and shown herein
Drafter can extend tens meters.Therefore reciprocating apparatus 1 equally has the track 3 of this length, it is certainly by multiple bearings 9
Supported.In addition, drafter or reciprocating apparatus 1 also have the multiple induction elements 4 for being used for guiding composite fibre 2.
The shortcomings that reciprocating apparatus 1 of prior art is that track 3 can not be promoted to pass through bearing 9 again from certain length.Rail
Road 3 has in bearing 9 prevents reciprocating first frictional resistance.In the case of with a large amount of bearings 9, driver 5 is not
Enough power can be expended again to promote track 3 to pass through bearing 9.
In addition, first frictional resistance of the track 3 in single bearing 9a, 9b makes the longitudinal direction before bearing 9a, 9b of track 3 curved
It is bent（From driver 5）.Therefore track 3 is bent in bearing 9a, 9b.Therefore compound fibre can not be realized by induction element 4a-4c
Tie up 2a-2f accurate guiding.
Contacted in addition, induction element 4a-4c and subsidiary drafter roll have, thus in induction element 4a-4c and
The second frictional resistance is formd between drafter roll.Therefore back and forth transported in induction element 4a-4c with moving back and forth Cb
When dynamic, it is also necessary to overcome second frictional resistance.Therefore in addition to first frictional resistance of the track 3 in bearing 9a, 9b, also
Second frictional resistance must be expended.
But the second frictional resistance also generates the power with the parallel orientation of track 3, it is in opposite direction simultaneously with moving back and forth Cb
And act on induction element 4a-4c.The power produces bending moment by linking arm 8a-8c length（Power and linking arm 8a-8c
It is mutually perpendicular to）, they are received by track 3.These bending moments exacerbate the buckling or bending of track 3, therefore guiding element
Part 4a-4c can no longer be guided with sufficiently high precision.
The buckling or bending can make the warpage in bearing 9a, 9b of track 3.So-called drawer is likely to occur herein
Effect.The warpage of track 3 prevents the reciprocating motion Cb of track 3 herein, therefore also prevents that composite fibre 2a -2f's is reciprocal
Motion.Composite fibre 2a-2f is then cut in drafter roll again, therefore they can be damaged and must in a short time
It must change.
If the in addition, track 3 that is temporarily lost with bearing 9a, 9b and warpage, warpage can also cause court immediately again
Reciprocating motion Cb afterwards.Therefore, this may damage reciprocating apparatus 1 and drafter.
These shortcomings should be able to be eliminated by the present invention.
By the present invention, reciprocating apparatus 1 has power-boost driving device 6 in the embodiment of fig. 2.If describe in Fig. 1
Feature has identical effect, then is repeated no more herein in order to simplify description.This is especially also applied for the following drawings.
On the rail end 7b that the power-boost driving device 6 is arranged on the relative with rail end 7a of the track 3 and put.Power-assisted is driven
Dynamic device 6 forms pneumatically or hydraulically cylinder in this embodiment.Power-boost driving device 6 also sets up coaxial with track 3.It will can lead
Gravitation Zk and pressure Dk are applied on track 3, therefore move back and forth Cb by least one formation in the two elements.Have
Profit, power-boost driving device 6 also can only apply tractive force, therefore power-boost driving device 6 that track 3 can further.
Power-boost driving device 6 so supports driver 5 so that and driver gives track 3 to load tractive force Zk, therefore along power-assisted
The direction of driver 6 pulls track 3.Power-boost driving device 6 may expend the 75% and 90% of tractive force Zk herein, to form track
3 reciprocating motion Cb.Driver 5 then only controls the corresponding sub-fraction of the power（Between 10% and 25%）, so that track 3 is stayed
Among Cb is moved back and forth.But power-boost driving device 6 may also expend the 100% of the strength herein, to form the past of track 3
Cb is moved again.Accordingly, driver 5 does not work to moving back and forth Cb.That is, power-boost driving device 6 loads to track 3
100% tractive force Zk, the power to driver loading 0%.Here, 100% equivalent to power（Tractive force Zk or pressure Dk）, it is must
Want, so as to by track place oneself in the midst of its move back and forth Cb among.Can be by the power of 100 newton here, moving back and forth Cb（Traction
Power and/or pressure）Formed.This is of course depend upon the quality of track 3, quantity of bearing etc..But in this embodiment, 100 newton
Equivalent to 100%.There was only tractive force Zk effects herein on the track 3.So without pressure Dk effects on the track 3.
Additionally or alternatively, also the tractive force to the loading of track 3 120%, driver 5 add power-boost driving device 6 to track 3
Carry 20% tractive force.100% is therefrom obtained again, and it is necessary, to form the reciprocating motion Cb of track 3.Certainly pass through
Opposite power comes balance driver 5 or the gap of power-boost driving device 6 and track 3.
By the share for the tractive force Zk for improving power-boost driving device 6, from the beginning it is avoided that track 3 is before bearing 9a, 9b
Square bending（From driver 5）.In addition, the second frictional resistance by induction element 4a-4c on drafter roll, is prevented
The effect of bending moment.By the share for the tractive force Zk for improving power-boost driving device 6, track 3 is stretched, and prevent bearing
9a, 9b bending or bending.
Advantageously, a pulling track 3.Therefore, track 3 is pulled to oneself by power-boost driving device 6.Moving back and forth turning for Cb
6 are disconnected on to point, and track 3 is pulled to oneself by driver 5.If track 3 arrives at driver 5, driver 5 breaks again
Open, and track 3 is pulled to oneself by power-boost driving device 6 again.
Additionally, power-boost driving device 6 can also give the on-load pressure Dk of track 3, so as in opposite direction（I.e. along track end
Portion 7a direction）Assist to move back and forth Cb.By alternately giving track 3 to load tractive force Zk and pressure Dk, can be formed reciprocal
Move Cb.
Herein for example it is possible that the tractive force Zk applied by power-boost driving device 6 has the absolute value higher than pressure Dk.
Therefore, with promotion（Pressure Dk）Compare, with higher power（Tractive force Zk）Pull the track 3.Therefore, power-boost driving device 6 is passed through
Avoid the bending of track 3.In this embodiment, remaining is applied to moving back and forth the necessary power of Cb by driver 5.
Power-boost driving device 6 can also form spring element or electromotion linearity driver.
In order to understand the positioning of driver 3, driver 5 has step-like disk 12, and it is revolved together by rotary motion Db
Turn.The section of section and at least one band second radius 15 of the step-like disk 12 also with least one the first radius of band 14, its
In the second radius 15 be more than the first radius 14.Sensor 13 is additionally provided with the fringe region of step-like disk 12, it can be borrowed
Two sections with two radiuses 14,15 are helped to can recognize that the position of step-like disk 12.Sensor 13 can be such as this
It is configured to grating, it will not be interrupted by the section with the first radius 14, but be interrupted by the section with the second radius 15.
