Abstract
The non-woven fiber guidance mechanism is proposed to have the following control aspects: the transfered non-woven fiber material is gathered at the outlet of a non-woven fiber material device, such as a spread non-woven fiber-drawing frame of a textile machine, so as to form a single sliver horn, which covers a horn region and a nozzle channel attached to a downstream direction, and a fiber band guidance mechanism with a covering guidance channel comprising guidance channel for guiding the fiber band leaving a fiber web tunnel to a band-withdrawal mechanism, such as controls of the guidance disc. The inventive non-woven fiber band guidance mechanism is charactered in that the non-woven fiber horn relative to the fiber band guidance mechanism can be moved from a running position to a maintenance position, where a continous guidance channel is formed between the a nozzle channel of the running position and the guidance channel. Finally, the textile machine is proposed to adopt an appropriate non-woven fiber guidance mechanism.
Description
Technical field
The invention relates to a cover and produce the guider of diffusion fiber non-woven thing equipment output end, for example, drafting system in the textile machine, with loudspeaker the fiber collecting of the nonwoven of output is become sliver, this device comprises by horn region, the bar-guiding device that downstream nozzle passage and sliver pipe are formed, and sliver pipe guiding sliver enters into the draw-gear of nonwoven guide device from the nonwoven loudspeaker, for example, carry-over pinch rolls device.
Furthermore, the invention still further relates to some textile machines, particularly drawing frame, carding machine or be used for is produced the combination machine of diffusion nonwoven, for example, and with the machinery of drafting system.
Background technology
Shown in EP0736617 B1, the clear nonwoven guider that is contained in the draft of drawing frame output that shown.When drawing frame is worked, the web of carding machine with extend type by the bottom roll of traction unit with turn to roller to guide to the zone of nonwoven loudspeaker.Therefore, nonwoven is folded and turns to, and then is imported in the nozzle passage of nonwoven loudspeaker.Nozzle passage has a circle to lean on the type cross section.Sliver comes therefrom.But the single fiber of sliver there is no any bonding.
At this moment, sliver is derived the nozzle passage in the sliver pipe of bar-guiding device, there from nozzle passage to the sliver pipe, change has taken place in sliver.The sliver pipe extends the clamping gap pressed close to traction wheel apparatus, and therefore, sliver is directed to the clamping gap and is gathered, and is derived by traction wheel apparatus.At this, the sliver pipe forms a tapered section, to compress sliver and to increase each single interfibrous bonding.Fibre bundle is entered in the spinning can (sliver can) or directly lead other textile machine, for example spinning machine owing to traction wheel apparatus further strengthens subsequently.
Opposite with fixing bar-guiding device, the nonwoven loudspeaker can be shifted to maintenance position from the running position.Downstream at bar-guiding device provides an interface, connects nozzle and bar-guiding device to reach the sealing of air.The position of ignoring the nonwoven loudspeaker at the bar-guiding device upstream extremity, is connected with the arc sealing surface that forms.And be adjustable between the relevant position of obturator.
Bar-guiding device has an injection apparatus that compressed air is sprayed into the sliver pipe.Because compressed-air actuated spraying into formed the attraction air-flow that flows downward in the sliver pipe, act on the horn region of nozzle passage and web loudspeaker, to reach air-tight connection.When drawing frame is worked, introduce air-flow and be used for the web of combing is incorporated into the guider of nonwoven.
In operation, observe operation instruction, may further comprise the steps:
At first, the operator moves on to maintenance position with the loudspeaker zone of web loudspeaker.Then, the operator drives the energy element of drawing-off equipment rapidly, derives a small pieces combing web from the drawing-off equipment.Subsequently, the operator compresses by hand and reduces the combing web of drawing, and simultaneously, is placed on the web loudspeaker zone of flare.Last operation person connects and introduces air-flow and web loudspeaker pendulum is got back to the running position.
Operation spending huge in installation is disadvantageous.With regard to guider, the practical experience of the nonwoven under the prior art condition also proves and can not guarantee.Even according to there being preparation to have the combing web of the production of planning to arrive in the nonwoven guider with introducing gas delivery.Other shortcoming is for example, in the time of changing the web loudspeaker, must require great effort and go to regulate the exact position of interface and sealing surface.
Simultaneously, the labyrinth that is directed to this position is very important, even through of short duration running, dust also will be stained with the joint portion of interface and sealing surface, because be difficult at this place's dust out.
Other shortcoming is that the nozzle passage of known nonwoven guider is suitable with the total length of sliver pipe.Special do not wish the shutdown that causes by sensor.Sensor is a part regulating textile machine, is installed in the downstream of nonwoven guider, is used for measuring the quality of sliver.
Especially for the sliver of homogeneous texture, the requirement to the sliver quality continues to improve in the past few years.Conventional device has been difficult to be suitable for.
In addition,, use the possibility of each independent component of nonwoven guider to be very restricted for the purpose of safeguarding, for example, cleaning or renewal part.
Summary of the invention
And task of the present invention is the nonwoven guider of a kind of improved textile machine of exploitation, and and then removes to develop a kind of improved textile machine.
This task is finished by nonwoven guider and textile machine with independent application characteristics.
According to the present invention, the web loudspeaker that the nonwoven guider shows can forward maintenance position to from the running position, and in the face of bar-guiding device.At least at operating position, nozzle passage and sliver guiding form a continuous guiding channel.Because bar-guiding device can reset, it is can be selectively that the complexity adjustment of handing-over and sealing surface requires.Ignored the complexity location of junction at this.Whole nonwoven guider can have compacter design, has suitable structure and control advantage.And the cleaning nozzle passage is to the overlay area of bar-guiding device easily.
At least in the running position, nozzle passage and guider are tightly connected.Be easier to reach setting like this on the nonwoven guider, the web loudspeaker can forward sliver guider dorsad on guider.If follow nozzle passage to the overlay area of sliver guider passage by following design, in the running position of nonwoven loudspeaker, nozzle passage and sliver guider radially are being air-tight.Therefore, this design has prevented that nozzle passage from attracting weakening of air-flow, and also can prevent to attract weakening of air-flow in the zone of subsequently web loudspeaker.Attracting weakening of air-flow is the formation because the air at the edge in the overlay area flows.This design helps guaranteeing to attract air-flow that the combing web of output is transported in the nonwoven guider.
Therefore, needn't force to excise certain-length web head.This setting is controlled by the control device of textile machine.And need not participate in by hand.The most at the beginning, web is carried can be full-automatic, and operation is significant for broken end for this.The form of the automation feeding of this web also is specially adapted to start once more the production of textile machine after the sensor effect.Especially under the condition of non-contact sensor, for example at microwave remote sensor.
When the web loudspeaker were in the running position, this configuration can reach.When maintenance position forwards operating position to, the drawing-off error of generation will have a negative impact to the combing web at the sliver guider.Just can be avoided with above-mentioned configuration.
Handing-over from nozzle passage to the sliver passage can have the flat design of a connection, so that reduce the harm of laying dust.Cause easy damage owing to ribbon is difficult to be compressed in the handing-over zone,, make it the sliver that to produce evenly and more tighten so use preferred methods.
The nonwoven guider that has removable web loudspeaker is exactly that nozzle passage outlet and sliver feeder connection separate fully.For example, this will help desired cleaning.For this reason, should take the defence measure, under maintenance position, keep the web loudspeaker to unclamping the nonwoven guider, and can under the situation of no any instrument, be moved.In a word, the nonwoven guider should be designed to easily near all parts.
Under the running position, connect the air-tightness of nozzle passage and sliver passage.For example, can adopt the O RunddichtringO that is made of elastomeric material, it is fixed on the web loudspeaker or in the annular ditch groove of bar-guiding device.But the position is in the nozzle passage exit preferably, and the sealing surface of web loudspeaker and in the porch of sliver passage adopts the sealing surface that is equivalent to bar-guiding device, and it is connected to each other in the running position not have the sealing that separates.This simple structure can reach the effect of sealing simultaneously.
Advantageously the sealing surface of web loudspeaker can be made the metal material identical with the web loudspeaker.And, the sealing surface of bar-guiding device can with bar-guiding device with identical metal material.Metal material is preferably consistent with nozzle passage or bar-guiding device passage.It is more permanent that this can make sealing be provided with, even still can keep operate as normal under the situation that the web loudspeaker often change.
Particularly advantageous is if web loudspeaker sealing surface and bar-guiding device sealing surface are all very smooth, for example, with simple method and high-precision polishing, just can be processed into smooth sealing surfaces.
If the nonwoven guider is very perfect, so, when the nonwoven loudspeaker change, the sealing surface of nonwoven loudspeaker and the mutual lateral sliding of the sealing surface of bar-guiding device meeting, thereby a simple structure arranged recently, promptly avoid damage to sealing surface by the vertical contact on surface.
Even this is possible, the nonwoven loudspeaker can be pushed by the route of bending, but preferably promote by straight line.For this reason, simpler method is to make the nonwoven loudspeaker that are fit to suspension.
Advantageously, the nonwoven loudspeaker can be promoted by level.Thereby can guarantee that the weight of nonwoven loudspeaker neither supports also not hinder this promotion.
Moreover, can promote the nonwoven loudspeaker across preferably for the sliver passage.Intersection should mean the nonwoven loudspeaker by what promote according to certain orientation, and it comprises with the sliver passage being at least 45 ° angle of longitudinal axis.Particularly, if promote the web loudspeaker at sliver channel vertical ground, i.e. 90 ° of angles draw the bar-guiding device of a cramped construction thus, particularly can reach length overall short nozzle passage and sliver passage.
Advantageously, at the output of nonwoven loudspeaker, be provided with the slidingsurface of nonwoven loudspeaker, its sliver sliding surface by the bar-guiding device arrival end is supported.At this, it provides the simple suspension arrangement of nonwoven loudspeaker.Slidingsurface can make nonwoven oppositely move from the running position to the maintenance position at this.Nonwoven loudspeaker sliding surface and bar-guiding device sliding surface can accomplish to avoid the nonwoven loudspeaker to topple over to bar-guiding device.In the horizontal movement of nonwoven loudspeaker, its weight can rely on the sliding surface of bar-guiding device.
Nonwoven loudspeaker sliding surface and bar-guiding device sliding surface be the plane preferably.This makes its easier generation sliding surface, and wearing face is arranged, and for example, handles by surface abrasion resistance.
Be more preferably, if adopt arresting stop, under the running position, it can stop nonwoven loudspeaker sliding surface to lift from the bar-guiding device sliding surface at least.Prevented also that simultaneously the separating of the non-setting of nozzle passage and bar-guiding device passage, for example, because the impact of external force, arresting stop can lock work by the front.
Arresting stop has magnet, preferably a permanent magnet at least.At least one magnet can be set at nonwoven loudspeaker or sliver loudspeaker place.It can interact with other magnet or interact with corresponding ferromagnetic material (as iron).
Arresting stop is used for preventing that the nonwoven loudspeaker from departing from the direction of setting in the running position.Equally, the bypass guider is used for preventing that the nonwoven loudspeaker are for moving that direction initialization is done to tilt.When running, arresting stop and bypass guider contact with the nonwoven loudspeaker.These can not hinder nonwoven loudspeaker moving by direction initialization.
Consider the displacement direction of setting, the permanent plant of nonwoven loudspeaker is in order to the nonwoven loudspeaker in the fixing running.This just can prevent for example non-setting displacement of the nonwoven loudspeaker of external force influence.
At this, nonwoven loudspeaker permanent plant has at least one locking member, and at least one pincers is held element, at least one magnet, particularly at least one permanent magnet.
Perfect especially nonwoven loudspeaker guider is that the rolling volume that the nonwoven that fixedly spreads on the delivery roller forms is passed away the nonwoven loudspeaker from the running position.If at least a portion nonwoven is around relevant roller rotation and around its rotation, you we can say to be exactly the volume that rolls.Curly hair is given birth to if roll, and that can not produce high-quality sliver again.Equally, the rolling volume can damage textile machine part on every side.If the nonwoven loudspeaker are rolled to roll up pushes away the running position, that will be handled.For example, operator's processing of shutting down.
In this process, on the nonwoven loudspeaker, make a surface, the rolling volume that utilizes delivery roller to produce acts on the mode that its surface promotes the nonwoven loudspeaker, is used.
Advantageously, if the inductor of catching nonwoven loudspeaker position is provided, so on the one hand, can prevent that machinery still is in operating condition when the nonwoven loudspeaker are in the outside, running position.On the other hand, when the volume that rolls had forced the nonwoven loudspeaker to break away from the running position, machine can be closed down or give the alarm automatically.
Bestly be, if the nonwoven loudspeaker are in the running position, the output section of nozzle passage and the input section of sliver passage are arranged on the same axis at least, thus sliver can linear fashion from nozzle passage guiding sliver passage.Therefore can prevent from the departing from of the branchpoint of nozzle passage guiding sliver passage, thereby improve the quality of producing sliver.
The advantage of nozzle passage and sliver passage is the linear guiding sliver.Thereby the sliver quality of producing also is improved.
If nozzle passage and sliver passage radially are being airtight, when from the attraction of bar-guiding device nonwoven being introduced the guider of nonwoven so, can be favourable.In addition, can prevent the appearance of positive draft, it can disturb transmitting along sliding of sliver.Radially be that airtight representative does not have air to enter or to leak from uncontrolled nozzle passage and sliver passage in the bypass direction.
The special feature of the guide channel that is made of nozzle passage and sliver passage is that in the running position, the nonwoven loudspeaker the variation in cross section can not take place when the gap.And can avoid in the continuous steerable passage, the adhesion of impurity has perhaps reduced at least widely.
Continuous guide channel only is made up of the face of cylinder and the conical surface.The conical surface can be made truncated cone.Advantageous particularly in the processing of nonwoven guider is because can process with the straightforward procedure of bore hole.
The more important thing is that bar-guiding device has comprised the compression section of sliver.This can be tapered section, particularly truncated cone.Each fibre compact area in the sliver is got together, and has been reinforced, and therefore, can produce the more stable sliver of mechanical performance.
Nozzle passage is the part of loudspeaker nozzle, and it can make the interchangeable plug-in unit of nonwoven loudspeaker.Various plug-in units are fixed on this and also can be mounted into, to adapt to the fineness degree of the processed raw material or the sliver that required.For example, the diameter of the nozzle passage that can change.
If the sliver passage is the part of sliver loudspeaker, make the interchangeable plug-in unit of bar-guiding device, that is just more favourable.
Nonwoven loudspeaker zone has a longwell at least, and it is made of cover plate, is manoeuvred into maintenance position from the running position, especially can be pushed or rotate.For cleaning, can improve the interior zone of nonwoven loudspeaker especially.Represented the raising of current automatic technology level at the removable cover plate in nonwoven loudspeaker zone.
In the running position, for fear of moving the cover plate that adopts a cover cover plate erection unit to install and fix at the vantage lower cover.The suggestion of cover plate permanent plant comprises at least one locking member, at least one jaw device, at least one magnet, preferably permanent magnet.
Good nonwoven loudspeaker can make at the nonwoven fiber that accumulates in the loudspeaker zone and promote cover plate during in the running position.When cover plate was pushed out the running position, the operator can pinpoint the problems and take measures necessary.
The cover plate sensor is the position that is used for catching cover plate.Can capture the position of cover plate with respect to the nonwoven loudspeaker.Can avoid like this, when cover plate not the time with respect to the running position of nonwoven loudspeaker pedestal, textile machine is still just in running.And, can shut down or report to the police, when causing cover plate to be pushed out the running position owing to sliver is overstocked.The cover plate sensor can be one one and induce sensor.
The cover plate sensor that designs well can capture the residing position of cover plate for bar-guiding device.Used this cover plate sensor, can check whether the nonwoven loudspeaker are in the running position, and simultaneously, whether cover plate is in the running position.By a sensor, can prevent that textile machine may be in operating condition under two all ungratified situations of said condition.When this cover plate sensor of utilization, need not use the nonwoven loudspeaker sensor of a separation.The cover plate sensor also can be an inductive pick-up at this.
For draw-gear, can be equipped with air compressing device.At this, the load of draft apparatus can be automatically conforms to the fibrous material coupling or with the operating condition of relevant textile machine.When entering the nonwoven guider, nonwoven also may reduce load when connecting.Even drafting unit that may mobile draft apparatus, for example, two drawing rollers owing to compressed air is separated from each other, can guarantee to arrive in the middle of the drafting unit so that sliver is held to the greatest extent when connecting.About the control of load, air-pressure equipment can link to each other with the control of textile machine.Equally, the driving of drafting unit can link to each other with the control of textile machine, so that it is automatically controlled.In the nonwoven equipment, also can adopt air-pressure equipment according to present technical merit.
Ad hoc proposal is used the method for air-pressure equipment to connect nonwoven and is entered the nonwoven guider.In this sets, be equipped with injection control to bar-guiding device.Be blown into compressed air by injecting control, in the bar-guiding device and nozzle passage that connect upstream and downstream,, produced the suction steam flow connecting in the loudspeaker zone of upstream more.Suck the nonwoven termination that steam flow is used to connect prior placement and enter the nonwoven guider.Particularly, the sliver that nonwoven comes out can be sent in the draft apparatus at once, helps just can be captured and drawing-off and need not handle.
Sliver departs from according to the output of given lead and is less than 30 ° of degree, and suggestion is less than 20 ° of degree, preferably less than 10 ° of degree.Set the sliver outbound course and be meant, direction initialization in the exit of nonwoven guider.Corresponding sliver incoming direction is meant, the direction initialization in the porch of nonwoven guider.If it is very small that two directions depart from each other, departing from controllable scope in the zone of nonwoven guider that is to say.Come therefrom, the stationarity of running can produce high-quality sliver.This is effective especially on the textile machine that runs up.
Bar-guiding device has a pedestal, and it can be done and enter oppositely moving of maintenance position from the running position.Therefore, from the purpose of safeguarding, draft apparatus is accessible.Be more preferably, pedestal can be made slurcam or oscillating plate.
In the invention of the textile machine that the equipment of exporting the diffusion nonwoven exports, adopted the invention of nonwoven guider.As mentioned above.
Carrying the equipment of diffusion nonwoven is horizontally disposed draft apparatus.Horizontally disposed draft apparatus requires the setting height(from bottom) of lower textile machine, so that the accessibility of draft apparatus.
In addition, carrying the equipment of diffusion nonwoven is vertically disposed draft apparatus.Vertically disposed draft apparatus requires the installing space of littler textile machine.Vertically disposed draft apparatus is particularly conducive to knockdown machinery, comprises carding machine and drawing frame.
According to the size in space, direction, introducing place of fibrous material, and the direction that rolls off the production line of fibrous material, it also is advantageous that the inclination of draft apparatus is installed.
In the exit, the deviation value of nonwoven is less than 60 ° of degree, and suggestion is less than 30 ° of degree, preferably less than 15 ° of degree.For example, the delivery roller on the device of output diffusion nonwoven is set.Thereby can operate in nonwoven in running up swimmingly.

The specific embodiment
Fig. 1 is a drawing frame 1, is the example of textile machine 1, and it has a drafting system 2, the diffusion fiber non-woven thing FV of output.Yet the present invention is related to OTHER TEXTILE MACHINERY 1, and particularly spinning preparation machine 1, and for example, carding machine or combing machine are studied carefully itself and opinion, drafting system 2 or other device 2 is all arranged, the diffusion fiber non-woven thing FV of output.
The task of drawing frame 1 is, will be from carding machine, and one or more feeding sliver that combing machine or preceding road drafting come out carries out and closes, and mixes drawing-off, parallel or regularization.Yet when carrying out, the high-quality sliver that high-speed running is produced at drawing frame 1 here, should be not difficult to carry out.
Schematic diagram is represented drawing frame 1, and guiding area 3 is arranged, and for example, 6 independently feed bar VB and feed one by one.Guiding area 3 and feeding bar VB are from pushing up, and drawing frame 1 only is a side view.
In the guiding zone 3 of drawing frame 1, be provided with loudspeaker 4, by it, the feeding bar is fed simultaneously, therefore feeds bar and is retracted.The feeding bar is initiatively drawn by loudspeaker 4 by traction roller 5a.5b.Wherein at least one traction roller 5a drives roller, another traction roller 5b can be developed into the common form as the autoleveller machine, as scan the part that roller 5b is again a measurement mechanism 11, it sends a measuring-signal Se (t), the quality of the unit length that this signal representative feeding sliver passes through.Se (t) is transported to the control device 10 of drawing frame 1, and is used for particularly changing the preliminary draft or the dominant draft of drafting system 2.Thereby the quality fluctuation of feeding bar VB gets more level and smooth.This kind program is the open loop of drafting system 2 control as known still.
Now, the also measured feeding bar VB of deflation is imported into drafting system 2 simultaneously.This drafting system is the nucleus of drawing frame 1.Drafting system 2 has a pair of feeding roller 6a, and 6b.6a is a bottom roll, and 6b is a top roller, middle roller 7a, and 7b, 7a are middle bottom roller, and 7b is a middle top roller, and a pair of delivery roller, and 9a is the output bottom roll, and 9b is the output top roller.Each top roller 6b, 7b, 9b are all pressed to corresponding bottom roll by pressue device.Thereby feeding sliver VB is clamped down on and is diffused into nonwoven FV.Each is to roller 6a, 6b, 7a, 7b, 9a, 9b, transmission increase progressively successively by separately peripheral speed.By each peripheral speed different to roller, the fiber non-woven thing FV of diffusion carries out drawing-off by the ratio of peripheral speed.
The pressure bar 8 that is attached to the dominant draft zone makes diffusion nonwoven FV deflection better lead to guarantee fiber.Drafted nonwoven FV concerns that by departing from top roller 9c is departed from, and is admitted to nonwoven guider 20.
The measurement device 12 of nonwoven guider 20 preferably comes work with non-contacting principle.The use of non-contacting measurement device 12 has special advantage, because the output speed of draft apparatus 2 is apparently higher than input in the reality.The shortcoming of the non-contact function of known measurement device 12 is as cubic content measurement equipment or microwave equipment, to need intermittent startup.For example, the startup of sensor will occur in the dry measurement environment.For the measurement environment of drying, need cut off nonwoven FV in the exit of draft apparatus 2, close down draft apparatus 2, and move the fibrous material of staying nonwoven guider 20 the insides by draft apparatus 26.Known to drafting do not let slip an opportunity under the situation, above-mentioned drawing frame is full automatic.But, after drying is measured, again nonwoven is automatically sent into nonwoven guider 20.
Do not show by the measuring-signal Sa (t) that measurement device 12 produces by electronic sensor, assess one by the qualified evaluating system of a cover and do not show.Especially confirmable is the average thickness of sliver and the irregularity in sliver.If the non-conformity of quality of output sliver closes requirement, so, for example, a signal can be transferred to control appliance 10 from quality monitoring device, then shutdown.Simultaneously also can transmit an information to the operator.
Measuring-signal Sa (t) at the measurement device 12 in the exit of draft apparatus 2 usually directly is transferred to control appliance 10.For example, because the generation of substandard products, the shutdown of fore-spinning machine 1 can be by control appliance 10 from motion tracking.It also is possible relating to the drawing-off measuring-signal Sa (t) that controls draft apparatus 2.The closed-loop control of widespread usage is particularly suitable for offsetting the fluctuation of long-term weight.What be worth expectation is, installs and measures equipment 12 in as close as possible draft apparatus 2 exits, sees it is in order to dwindle the disadvantageous lost time from the control angle.
Sliver FB after the measurement is drafted and send into bar cartridge system 15 by draft apparatus 26.Bar cartridge system 15 has a rotating disk 17 that rotates around vertical axis, has one sliver FB is stored at a sliver passage 16 in tins 18 on the axle.Tube 18 is accompanied by relevant fixing rolling disc 17 together, moves one by the method and does not show, when the rectangle tube is mobile nearby, when cylinder is then to rotatablely move.Therefore, tube 18 the totality space sliver FB that can be stored fills up.When tube 18 all fills up, can not show by operator's craft or by a creeling equipment one and change.
The control appliance 10 of drawing frame 1 is controlled several rpm to roller of draft apparatus 2 especially.It has influence on several transmissions one to roller and does not show for this reason.Equally, control appliance 10 has influence on traction roller 5a, the transmission of 5b, the transmission of draft apparatus 26, the transmission of rotary disk 17 and tube 18.Control appliance 10 also can be developed as control creeling equipment.In this exploitation, control appliance 10 links to each other with running device, for example, and keyboard, output unit, display.
Fig. 2 a represents the side diagrammatic sketch of nonwoven guider 20.Fig. 2 b represents a relevant positive diagrammatic sketch.Fig. 2 a and 2b do not concern in proportion, still duplicate, as other figure ratio roughly.Being illustrated among this and the later figure of the measurement device 12 of nonwoven guider 20 is in simple and clear former thereby be left in the basket.
Bar-guiding device 24 is installed on the downstream of nonwoven loudspeaker 21, has covered sliver passage 25, and its section 41 is used for compressing sliver FB.Draft apparatus 26 is connected the downstream of bar-guiding device passage 26.
24 are unconsciously promoted for fear of nonwoven loudspeaker 21 from bar-guiding device, and the section that this may be divided into sliver passage 23,25 two separation can use arresting stop 31, and it has 4 permanent magnets, just in time is close to the pedestal 50 of bar-guiding device 24.Permanent magnet 31 also can be fixed on the nonwoven loudspeaker 21.In institute's example, permanent magnet 31 interacts with the section of nonwoven loudspeaker 21, and it has the composition of iron or iron content to constitute.In order to interact, permanent magnet is installed again at nonwoven loudspeaker 21 places.Equally, the section of nonwoven loudspeaker 21 can be made of different ferromagnetic materials or the material that contains this material.
Adopt block 32, it prevents that nonwoven loudspeaker 21 from deviating from forward from running position B1 and cutting out given swaying direction.The locking device 34 of nonwoven loudspeaker is used for preventing that nonwoven loudspeaker 21 from making unintentionally with swaying direction VR rapidly moves.The locking device 34 of nonwoven loudspeaker has comprised two permanent magnets 34, is installed in block 32 places.
For more among a small circle, nonwoven loudspeaker locking device 34 is simultaneously also as preventing the lifting of nonwoven loudspeaker 21 from bar-guiding device 24.Thereby nonwoven loudspeaker locking device 34 is supported the function of locking member 31.On the other hand, locking member 31 is also supported the function of nonwoven loudspeaker locking device 34, is running through from nonwoven loudspeaker 21 to bar-guiding device 24 drawing-off, and the friction of nonwoven loudspeaker 21 bite when being in running position B1.
The coiling form of the output of roller 9a, the fiber non-woven thing FV of at least a portion output is drawn between bottom roll 9a and the nonwoven loudspeaker 21.At this, act on the power of nonwoven loudspeaker 21, loudspeaker 21 have element among the expection direction of displacement VR.Nonwoven loudspeaker guider 20 improves, and its component is to satisfy the oscillatory forces of nonwoven loudspeaker 21 for bar-guiding device 24.Can detect this swing by nonwoven loudspeaker sensor 36.Nonwoven loudspeaker sensor 36 contacts with drawing frame control appliance 10, so control appliance 10 can be closed down drawing frame automatically.It also can send alarm signal to the operator.
Not movable inclined towards the direction VR that sets swing in order to ensure nonwoven loudspeaker 21, the side of guider 33 adopts positive lock.
The horn region 22 of nonwoven loudspeaker 21 has a long sidewall panel 44, and it makes the vibration cover plate 44 around vibrating shaft 51.At running position B2, be fixed by cover plate locking device 46 this moment.Cover plate locking device 46 comprises two permanent magnets 46, and the non-rotating section of each magnet and nonwoven loudspeaker 21 interacts.This section is made of ferromagnetic material.The material of iron or similar component for example., also can use dead-beat magnet.In order to catch the position of cover plate 44 dealings, or whether definite cover plate sensor 47 at running position B2, cover plate sensor 47 is housed captures cover plate position 44 with respect to nonwoven loudspeaker 21 pedestals.For this reason, it is arranged on the pedestal of nonwoven loudspeaker 21.
If the nonwoven FV of input continuously takes place in the horn region 22 at nonwoven loudspeaker 21, so will be in power of effect of cover plate inboard.At this, perfect nonwoven guider, this active force are enough to push the running position B2 that cover plate 44 leaves expection.Can catch this situation by the cover plate sensor 47 that is connected with control appliance 10.Controller 10 can be closed down drawing frame or trigger alarm and be shown.
Above-mentioned permanent magnet 31,34,46 also can be designed to electromagnet.Therefore controlled at actual conditions in a simple mode with electromagnet power, for example, by control appliance 10.
The traction of nonwoven guider 20 equipment 26 has fixing or drivable first a traction roller 26a and second a traction roller 26b who movably hangs.The latter is suspended on the block 53, and they can be around axle 54 vibrations.Block 53 pressurizes by air compressor machine 48, and this method also can make mobile suspension roller 26b press to fixing traction roller 26a. air compressor machine 48 and control automatically by controller 10.In this way, traction roller 26b can automatically remove from traction roller 26a, can form a space between the two.
In the running of nonwoven guider 20, show that as Figure 26 a and 26b loudspeaker 21 are at running position B1, cover plate 44 is put B2 at a driving position, and the base plate 50 of bar-guiding device 24 is at running position B3.On-stream, exit bottom roll 9a and reverse top roller 9c transfer out nonwoven FV, for example, and thick 10mm and sprawl wide 20cm.Nonwoven FV enters the loudspeaker zone 22 of nonwoven loudspeaker 21 with nonwoven traction Inbound ER, forms fiber sliver FB at this.Fiber sliver FB arrives nozzle passage 23 places, itself and 22 airtight joining of horn region.Because nonwoven loudspeaker 21 are in running position B1, nozzle passage 23 and lead cotton passage 25 and formed a continuous guide channel 23,25, thus, sliver FB is by nozzle passage 23 and lead cotton passage 25 and can arrive pulling equipment 26, lead cotton passage 25 form one decrescence section 41 compress sliver FB.This section 41 is also referred to as the sliver loudspeaker.
For fiber non-woven thing FV is penetrated its guider 21, must adopt drawing frame 1.Nonwoven loudspeaker 21 are at running position B1 at this moment, and cover plate 44 is at position B2, and the base plate 50 of bar-guiding device 24 is at position B3.When connecting, the front end of sliver FV is directed to loudspeaker zone 22 by drafting system.Can control the running of drafting system 2 automatically by control appliance 10 for this reason.And, by injection apparatus 49 compressed air is blown into.Injection apparatus 49 has more detailed description subsequently.
Spraying into of compressed air is in continuous steerable passage 23,25 and loudspeaker zone 22, attract air-flow can follow upstream end closely and occur, capture fiber non-woven thing FV at this, and draw it to guide channel 23,25, where fiber non-woven thing FV is collected to form sliver FB.Why becoming possibility, is owing to do not adopt hinged design in the invention of nonwoven guider 20 in continuous guide channel 23,25.At this, prevented that air from flowing to hinged region from the edge, do not weakened thereby suck air-flow.Hinged owing to not having, just need not take the measure of any complexity.
The front end of fiber sliver FB enters into the zone of the first traction roller 26a and the second traction roller 26b by air-flow.
In the stage of connecting, the pressure that can move traction roller 26b can alleviate, and for example, controlled by control appliance 10, thereby the front end of sliver FB can reach between traction roller 26a and traction roller 26b, and be held by roller.Also can pass through loading element 48 in addition, drawing rollers 26a and drawing rollers 26b are separated a space.After sliver FB is pulled roller 26a and traction roller 26b and has captured, can reset pressure by normal value.
Drive traction roller 26a and carry out following running control, make the fiber sliver FB that completes in advance after completing on the draw-gear 26, just drawn from sliver passage 25 by control appliance 10.The sliver transmission direction LR that fiber sliver FB is configured with one then derives from the zone of nonwoven device 20.Because the nonwoven lead ER that has departed from setting that sliver transmission direction LR is only trickle, this is expression just, in the zone of nonwoven device 20, nonwoven FV more only depart from or fiber sliver FB following closely, can produce a high-quality especially fiber sliver FB.Therefore, by the invention of nonwoven guider 20, making fully automatically connect fiber non-woven thing FV the first time becomes possibility.
Fig. 3 represents, the sectional drawing of nonwoven guider 20 inventions.This shows that nozzle passage 23 is parts of loudspeaker nozzle 42, it makes the interchangeable plug-in unit of replaceable nonwoven loudspeaker 21 bases 56.By replacing loudspeaker nozzle 42, the shape that can be easy to replace nozzle passage 23 for example, is complementary with the material or the thickness that overlay fiber non-woven thing FV to reach it.
Fig. 4 represents, the sectional drawing of loudspeaker nozzle 42.Here can be considered to, nozzle passage 23 has a downstream section 37, is column type, and same, upstream section 40 is to be cone-shaped.At this, lead to the section 37 and 40 of nozzle passage 23, without any the sudden change cross section.In a word, loudspeaker nozzle 42 makes nozzle passage 23 radially airtight.And then, in the outlet of nozzle passage 23, adopted more perfect nonwoven loudspeaker sealing surface 27.
Fig. 5 represents, the sectional drawing of sliver loudspeaker 43.Sliver passage 25 has the side direction section 38 of a cylindric arrival end and the side direction section 39 of a cylindric port of export, and between is cone-shaped section 41.The side direction section 38 of arrival end has the cross section identical with the side direction section 39 of the port of export of loudspeaker nozzle 42.The effect of middle discontinuity surface 41 is fiber sliver FB that compression will be passed through.Spray orifice 63 and 64 merges at side direction section 39 places of the port of export.The mutual handing-over of section 38,41,39 no any sudden change on the cross section of sliver passage 25.So the sliver loudspeaker 43 of exploitation have caused the sliver passage in radially air- tightness.Nozzle 63 and 64 existence do not impair it, are radially entering or are leaking because there is no air at this.
By the continuous steerable passage 23,25 that loudspeaker nozzle 42 and sliver loudspeaker 43 constitute, form column type section 37,38,39 and cone-shaped section 40,41 together.
Make a uniform sliver sealing surface 28 in the porch of sliver passage 25.As long as nonwoven loudspeaker 21 are at running position B1, it is closed with nonwoven loudspeaker sealing surface 27 under mounting condition and makes air airtight.Adopt the seal of non-separation for this reason.Why feasible because loudspeaker nozzle 42 and sliver loudspeaker 43 the same be to be made of metal.Therefore nonwoven loudspeaker sealing surface 27 and sliver sealing surface 28 can be very accurate and durable processed come out.Nonwoven loudspeaker sealing surface 27 and sliver sealing surface 28 are installed well, make when the promotion nonwoven loudspeaker 21 direction VR according to setting move slip that can be relative.
Fig. 6 represents the side view of nonwoven guider 20.Nonwoven loudspeaker 21 show that it is at maintenance position W1 herein.Nonwoven loudspeaker 21 are shifted maintenance position W1 from the running position B1 that shows onto with rectilinear direction.The conversion direction VR that sets is a level, and is just intersecting with respect to sliver passage 25, promptly perpendicular to sliver passage 25.
Be provided with the sliding bevel 29 of nonwoven loudspeaker at the outlet front end of nonwoven loudspeaker 21, its sliding surface 30 by the arrival end that is located at bar-guiding device 24 supports.If nonwoven loudspeaker 21 are at maintenance position W1, simultaneously, if when the B1 of running position, this just is suitable for simultaneously.The sliding bevel 29 of nonwoven loudspeaker and bar-guiding device sliding surface 30 are made into flat to prevent the inclination of nonwoven loudspeaker 21.The weight of nonwoven loudspeaker always is supported on the bar-guiding device sliding surface 30.
When bottom roll 9a outlet takes place around roller, shift maintenance position W1 for guaranteeing nonwoven loudspeaker 21 onto from running position B1, on nonwoven loudspeaker 21, be provided with a surface 35 for this reason, can exercise active force by the conversion direction VR that sets at this place's coil.
Fig. 7 a, 7b represent the invention of nonwoven guider 20, and at this, cover plate 44 is that the nonwoven loudspeaker 21 when maintenance position W2 are done backswing.
Fig. 8 a, 8b represent to have the nonwoven guider 20 of the nonwoven loudspeaker 21 that suitably move.Rely on the suspension of nonwoven loudspeaker 21, can mobile easily bar-guiding device 24 so that the latter is close to easily from the top, reach cleaning purpose.
Fig. 9 represents suitably mobile nonwoven loudspeaker 21, and the base 50 of bar-guiding device 24 can rotate into maintenance position W3 around runout axle 52.Wherein base 50 can enter maintenance position, especially when suitable installation nonwoven loudspeaker 21.If base 50 is at maintenance position, draft apparatus 26 can be approaching from the top so.
Figure 10 represents the another kind of configuration example of nonwoven guider 20.Its difference is that with the place of above narration cover plate sensor 47 is not arranged on the nonwoven loudspeaker 21, but is positioned on the bar-guiding device 24 by support 54.Therefore the position of cover plate sensor 47 is the position that is independent of nonwoven loudspeaker 21.Therefore, the position of cover plate 44 determine relevant with bar-guiding device 24 positions.
When nonwoven loudspeaker 21 are in running position B1, and cover plate 44 is when being in running position B2 simultaneously, and cover plate sensor 47 can produce a signal.If one of these necessary conditions are non-existent words at least, for the textile machine 1 of an operate as normal, this signal can or stop its running as the startup that stops textile machine 1.
Because cover plate sensor 47 is also monitored the nonwoven loudspeaker 21 of relative bar-guiding device 24, thereby the nonwoven loudspeaker sensor of a separation can be omitted.
The present invention is not limited only to the example representing and describe.Departing from the scope of patent application is always possible.
