The present invention relates to a kind of fleece-laying apparatus of balladeur train cross lapping machine type, have a fixing fiber web inlet, wherein operation has one of endless conveyor to go up balladeur train and one and lay balladeur train respectively, also has the laying deflector roll, between described laying deflector roll, form and lay the slit, be sent on the exit conveyor with carded web that will be to be laid, above described exit conveyor, the throughput direction transverse to band in frame movably guides two balladeur trains.
Background technology
The fleece-laying apparatus of the above-mentioned type is disclosed in " Vliesstoffe " (bondedfibre fabric) that W.Albrecht, H.Fuchs and W.Kittelmann showed (WILEY-VCH publishes, Weinheim, 2000, the 161 pages).The advantage of such fleece-laying apparatus is that to participate in the operating path of the conveyer belt that carded web carries very simple.Yet carded web is opened wide by the path of lapping machine, and lays fiber web and equally also open wide on exit conveyor.Therefore carded web is subjected to very strong pneumatic action, and described pneumatic action is derived from the motion of balladeur train, and causes dispelling of fiber, causes that also the fiber web laying that especially produces at the edge of laying bondedfibre fabric is inhomogeneous.Therefore the operating rate of this fleece-laying apparatus is very limited, for this reason, this type of lapping machine is replaced by biobelt lapping machine, in biobelt lapping machine, guiding flatly between two conveyer belts of bilateral when machine is passed through in the fiber web operation, the reason that Here it is is referred to as " sandwich-type lapping machine ".In the lapping machine of the above-mentioned type, conveyer belt also is used for the fiber web that is laid on the exit conveyor is covered, and protects it to avoid aforementioned flow perturbation thus.
Known described " interlayer " formula fleece-laying apparatus from European patent EP 0 865 521 B1, the carded web conveyer belt of wherein supplying with carded web both also passed through to lay balladeur train by last balladeur train, by an auxiliary balladeur train, described auxiliary balladeur train can be transverse to exit conveyor operation to and fro thereunder in addition.Should support a tensioning deflector roll by auxiliary balladeur train, and be used to keep described carded web conveyer belt to be in tensioning state.The second carded web conveyer belt moves through last balladeur train equally and lays balladeur train, and subsequently by the second auxiliary balladeur train, the described second auxiliary balladeur train can be in frame transverse to exit conveyor back and forth operation thereunder.This second auxiliary balladeur train supports another tensioning deflector roll, and is used to keep the second carded web conveyer belt to be in tensioning state.In last balladeur train, the operation of the carded web conveyer belt of the supply carded web that arrives in prerequisite is by two deflector rolls, and these two deflector roll settings are gone up at various height, and axially offset with respect to each transverse to it, thereby form a downward-sloping web portal.The web portal of this inclination is accompanied by the second carded web conveyer belt in last balladeur train, be parallel to the first carded web conveyer belt in the zone after the described second carded web conveyer belt between last balladeur train and laying balladeur train and extend, and surround carded web to be laid with the form of interlayer with it.The radius that centers on owing to different can't move on the following rotaring forward roller of these two carded web conveyer belts in last balladeur train parallel to each other, and described difference may cause rubbing action around radius, the carded web of infringement guiding.Therefore the second carded web conveyer belt is before it is once more near the first carded web conveyer belt, crosses altogether four independently rotaring forward rollers in last balladeur train in described time rotaring forward roller zone.Also take appropriate measures at the first carded web conveyer belt of laying in the balladeur train, because come from above-mentioned identical reason, this conveyer belt can not together import in the laying gap of laying in the balladeur train with the second carded web conveyer belt.
Cause thus these two carded web conveyer belts at last balladeur train and lay have a lot of band turning points in the balladeur train, very complicated route.
Summary of the invention
The fleece-laying apparatus that the purpose of this invention is to provide a kind of aforementioned type, when keeping the simple stroke of band that the peculiar participation carded web of balladeur train formula cross lapping machine transmits and carded web guides, avoid the machine that dispels and allow thus of fiber under higher speed, to work.
For achieving the above object, the fleece-laying apparatus according to the invention provides a kind of balladeur train formula cross lapping type comprises:
Fixing carded web inlet;
Last balladeur train and laying balladeur train, wherein operation has endless conveyor respectively; And
Be installed in two laying deflector rolls laying in the balladeur train in parallel to each other with equal height, lay the gap and be transported on the exit conveyor laying to form between the deflector roll with carded web that will be to be laid, above exit conveyor, throughput direction transverse to exit conveyor in frame movably guides two balladeur trains, wherein
A) lay the balladeur train conveyer belt around the first laying deflector roll, the epimere of this band and hypomere are laid deflector roll extension parallel to each other from first;
B) the circulation cover tape of operation process laying balladeur train is around the second laying deflector roll, and the epimere of this cover tape and hypomere are laid deflector roll from second and be in reverse to the extension parallel to each other of laying balladeur train conveyer belt; And
C) carded web enters the mouth, goes up balladeur train, lays between balladeur train and the exit conveyor so little perpendicular to the distance on the direction of throughput direction, so that between the adjacent band section of carded web inlet conveyer belt and last balladeur train conveyer belt with form surround the first of carded web to be laid, and surround the second portion of carded web to be laid with the form of sandwich between the adjacent band section of last balladeur train conveyer belt and laying balladeur train conveyer belt, the fiber web of having laid on the exit conveyor contacts with cover tape with laying balladeur train conveyer belt.
For achieving the above object, in last balladeur train, second rotaring forward roller that is centered on by the hypomere of carded web inlet conveyer belt is closely adjacent on identical height with first rotaring forward roller that the balladeur train conveyer belt is turned to according to the present invention.The 3rd rotaring forward roller is installed in last balladeur train, and the hypomere of carded web inlet conveyer belt is walked around this rotaring forward roller and second rotaring forward roller that leads.In distance is laid deflector roll zone farthest, guiding laying balladeur train conveyer belt and cover tape are through the rotaring forward roller of a diameter less than the laying deflector roll respectively, wherein, between each rotaring forward roller and the laying deflector roll of attaching troops to a unit a conveyer belt separating device is set, each separating device keeps laying the extension parallel to each other between the separating device and the laying deflector roll of attaching troops to a unit of the epimere of balladeur train conveyer belt and cover tape and hypomere; And, described rotaring forward roller is arranged on such one first height and position, makes described conveyer belt epimere continue to extend in the mode of the part of extending between rotaring forward roller and the conveyer belt separating device with the straight line extendible portion of the adjacent conveyer belt part between the conveyer belt separating device and the laying deflector roll of attaching troops to a unit.The rotaring forward roller of minor diameter is supported in the support respectively, can make it highly move to second height from first respectively by support, on second height, the hypomere of described conveyer belt continues to extend in the mode of the part of extending between rotaring forward roller and the conveyer belt separating device with the straight line extendible portion of the adjacent conveyer belt part between the conveyer belt separating device and the laying deflector roll of attaching troops to a unit.The support that is used for the rotaring forward roller of minor diameter is designed to, and first and second height and positions are stable terminal positions, has unsettled centre position between these terminal positions.Constituting the drive unit that extends laterally on the rotaring forward roller of minor diameter or on its support, and such device is set in frame, described device is transformed into rotaring forward roller according to its direction of motion the position of first or second height when laying sledge movements.Each lay deflector roll and the conveyer belt separating device of attaching troops to a unit with it between establish the belt support device, this belt support device supports the epimere of described conveyer belt from the below.The belt support device is set in last balladeur train, and this device is gone up the epimere of balladeur train conveyer belt from the below supporting.First and second rotaring forward rollers in the last balladeur train intermesh.The laying deflector roll intermeshes, and the engagement of one of them and cog belt, and described cog belt passes the laying balladeur train, and by being supported on turning to and driven wheel guiding and driving in the frame.Last balladeur train conveyer belt is breathed freely.
With the contrast of known balladeur train formula cross lapping machine, in fleece-laying apparatus of the present invention, carded web from the carded web inlet until be laid on stroke on the exit conveyor no longer be open wide but sealing is similar to the situation in " sandwich-type " lapping machine.This means and to avoid fiber to be subjected to the pneumatic influence that the motion by balladeur train and conveyer belt brings.But meanwhile keep simple guiding to band.Therefore no longer need the auxiliary balladeur train that uses in known " sandwich-type " lapping machine, this need make the motion of main carriage independently of one another, carded web entrance velocity that they can compensating equalization and carded web are laid the poor of speed thus, and described carded web lays that speed is inevitable when laying the reversing of motion of balladeur train to be changed to some extent.The present invention also replenishes a circulation cover tape of only moving for fleece-laying apparatus in laying balladeur train, with the pneumatic or mechanical effect that prevents to lay in the little gap between balladeur train and the exit conveyor fiber web that is laid on the exit conveyor is caused damage.The invention enables laying balladeur train conveyer belt hypomere and cover tape to be laid on the fiber web of having laid.
The cover tape of circular flow also centers at a certain distance away from being installed in the rotaring forward roller of laying in the balladeur train not only around constituting one of laying deflector roll of laying the border, gap with laying deflector roll in laying balladeur train.This rotaring forward roller is supported and adjustable height, and it considers to lay the direction of motion of balladeur train in special mode.That is to say, if make the diameter of the diameter of rotaring forward roller less than the laying deflector roll of attaching troops to a unit, so, height by adjusting rotaring forward roller and take other in the back with the measure that describes in detail can be so that cover tape can both cover the fiber web of having laid well on two directions of motion of laying deflector roll.This feature also can be applied to lay the balladeur train conveyer belt back to that side of laying deflector roll, thereby makes the laying balladeur train can both have aforesaid advantage on two directions of motion.
According to a further aspect in the invention, carded web inlet is maintained fixed like that as the common practice in the balladeur train formula cross lapping machine, it can but also needn't be downward-sloping.Carded web from carded web inlet move in last balladeur train circular flow on the balladeur train conveyer belt.Should go up balladeur train conveyer belt and preferably can breathe freely, so that the towing air-flow that is carried by carded web can as far as possible unhinderedly be discharged.Avoid like this fiber is dispelled.Carded web a turning point place from the balladeur train conveyer belt transfer to and lay on the balladeur train conveyer belt, this layings balladeur train conveyer belt circulates in laying balladeur train, and together with the hypomere of last balladeur train conveyer belt carded web is imported the laying gap.The carded web inlet conveyer belt that carded web causes in the inlet region is followed the turning point of carded web until last balladeur train place.But can carded web be directed to always the epimere of laying balladeur train conveyer belt at this place, can be by additional rotaring forward roller, to avoid causing friction effect because of the radius of curvature difference, guide to another rotaring forward roller subsequently, this rotaring forward roller with in laying balladeur train, make the balladeur train conveyer belt be located at same height and position at the rotaring forward roller that carded web deflects to the turning point deflection of lapping balladeur train.
The present invention has aforesaid advantage, promptly treats the carded web channeling conduct of laying with real " interlayer " form.For making the fleece-laying function be applied to the carded web of different thickness, according to improvement of the present invention, between carded web inlet and last balladeur train and in last balladeur train and the zone of laying between the balladeur train, the conveyer belt of guiding carded web can be adjusted their height and position-this being adjusted in the fleece-laying apparatus of the present invention relative to each other and guide and realization very easily owing to its simple conveyer belt.The spacing of conveyer belt can level off to zero in this zone.As long as make balladeur train just much of that for this reason with the adjustable height of the tracks of laying balladeur train.By adjusting the height of conveyer belt, produce contacting of expecting between the hypomere that can make the hypomere of laying the balladeur train conveyer belt and cover tape and the fiber web of having laid, and form slight extruding from start to finish.
The embodiment that represents referring to accompanying drawing describes the present invention in detail.

In illustrated embodiment, the conveyer belt (below be referred to as carded web inlet conveyer belt 6) that transports carded web is by last balladeur train 4, and this conveyer belt operation is through a plurality of rotaring forward rollers that are supported in the frame 3.Carded web inlet conveyer belt 6 does not pass lays balladeur train 5, but the side is passed through from it.In case of necessity also can be from last balladeur train 4 other processes, and do not follow carded web to be transmitted 11 to laying balladeur train 5 always.
The carded web entry position is fixed, and has two be arranged on the differing heights and the rotaring forward roller 8 and 9 that staggers of side direction each other in illustrated embodiment, thereby forms downward-sloping carded web inlet.Carded web inlet conveyer belt 6 is descending rotaring forward roller 9 places deflection above 90 °, and preferably be provided with at this place one fixing but resilient carded web guiding device 10 is relative with it, this carded web guiding device 10 is used to strengthen the guiding of the carded web 11 that carded web inlet conveyer belt 6 is transmitted, and be preferably ventilative so that unhinderedly discharge the air that from carded web, carries.
Two rotaring forward rollers 18 that are parallel to each other and 19 are supported in the balladeur train 4, form the gap thus between them.The first circulation carded web pilot tape (hereinafter deserving to be called balladeur train conveyer belt 20) is around first rotaring forward roller 18.This conveyer belt also pile warp is supported on the 3rd rotaring forward roller 21 in the balladeur train 4.In addition, the 4th rotaring forward roller 22 is parallel to two rotaring forward rollers 18 and 19 that form the gap and is supported in the balladeur train 4.Last balladeur train conveyer belt 20 is preferably breathed freely, and for example it is designed to the mesh band, surrounds carded web in the mode of sandwich thus between carded web inlet conveyer belt 6 and last balladeur train conveyer belt 20, successfully discharges the air that extrudes from carded web thus.Avoided the effect of advertising of fiber like this.
On the guiding device that preferably is installed on to adjustable height in the frame, guide balladeur train 4.In this way, can change enter the mouth distance between conveyer belt 6 and its opposed part of the epimere 20o that goes up balladeur train conveyer belt 20 and carded web, thereby for example make this distance be adapted to the thickness of the carded web 11 of being processed.
The carded web inlet conveyer belt 6 of supplying with carded web 11 is from the carded web inlet of rotaring forward roller 9 down, be parallel in last balladeur train 4 circular flow on the epimere 20o extension of balladeur train conveyer belt 20.This carded web inlet conveyer belt 6 is walked around the 4th rotaring forward roller 22 subsequently from first and second rotaring forward rollers 18 in formation gap and 19 top process, walks around second rotaring forward roller 19 that constitutes the gap subsequently, begins to be parallel to exit conveyor 2 from this and extends.It returns carded web inlet 8,9 by fixing rotaring forward roller then, at least one in the described fixedly rotaring forward roller, and for example deflector roll 28, are by motor-driven.This conveyer belt also can be breathed freely.
Last balladeur train conveyer belt 20 between rotaring forward roller 18 and 21 the distance of process, depend on that this length depends on the stroke of balladeur train 4 in the length of waiting to be laid on the combing network segment on the balladeur train conveyer belt 20 between rotaring forward roller 18 and 21, promptly depend on the laying width.Described laying width is significantly smaller than the distance between the rotaring forward roller usually, and can utilize width corresponding to the maximum of exit conveyor 2.Advantageously, for example support the epimere 20o that goes up balladeur train conveyer belt 20 from the below, to avoid the effect of advertising of conveyer belt vibration and the fiber that causes thus by a smooth plate 26.
Lay balladeur train 5 and be arranged on the below of balladeur train 4, and can as last balladeur train 4, above exit conveyor 2, move along the direction of arrow X is round transverse to its direction of transfer.The first laying deflector roll 12 and second is laid deflector roll 13 and is rotatably supported in the laying balladeur train 5 with narrow and small spacing.The laying balladeur train conveyer belt 14 of circular flow in laying balladeur train 5 is laid deflector roll 12 around first, this conveyer belt is also walked around the rotaring forward roller 15 and the conveyer belt separating device 16 of minor diameter, described rotaring forward roller 15 is bearing at a distance of first with laying deflector roll 12 certain distances and lays in the balladeur train 5, and described conveyer belt separating device 16 is made of the guiding deflector roll 16 of two minor diameters.The cover tape 23 of circular flow in laying balladeur train 5 is laid deflector roll 13 around second of another laying border, gap of formation equally, this cover tape operation is through the rotaring forward roller 24 and the conveyer belt separating device 25 of another minor diameter, and described conveyer belt separating device 25 is made of the conveyer belt guiding deflector roll of two minor diameters." minor diameter " refers to the diameter of laying deflector roll and compares littler diameter herein.At two laying deflector rolls 12 and 13 places, two through laying balladeur trains be with 14 and 23 between form one and lay the gap.
Conveyer belt separating device 16 and 25 be used to make in laying balladeur train 5, move with 14 epimere 14o and hypomere 14u between, and with remaining parallel to each other between 23 epimere 23o and the hypomere 23u, that is it is parallel to each other, to remain on the part of extending between conveyer belt separating device and the associated laying deflector roll 12 and 13.Described with 14 and 23 rotaring forward roller 15 and 24, that is, distance is laid the adjustable height of deflector roll 12 and 13 deflector rolls far away for the conveyer belt separating device, shown in four-headed arrow Y among the figure.
Lay between the rotaring forward roller 15 of deflector roll 12 at the lower conveyor belt guiding deflector roll of conveyer belt separating device 16 with away from first around the first laying balladeur train conveyer belt 14 of laying deflector roll 12 and to form certain band section, when laying balladeur train 5 to left movement, this band section is inclined upwardly, this is that rotaring forward roller 15 is placed in the lifting position shown in the figure because in this case.When this direction of motion, as shown in the figure, the rotaring forward roller 24 of cover tape 23 descends, thereby makes the hypomere 23u of cover tape 23 can cover the fibroreticulate whole width that is laid to by carded web.When laying balladeur train 5 along the opposite direction of motion, rotaring forward roller 15 drops to the height of the lower conveyor belt guiding deflector roll of conveyer belt separating device 16, and rotaring forward roller 24 rises to the height of the upper conveyor belt guiding deflector roll of conveyer belt separating device 25.Preference is as being bearing in the horizontally extending part with 14,23 epimere 14o, 23o of laying operation in the balladeur train 5 from the below by smooth plate 27, with avoid with vibration.
Similar with last balladeur train 4, balladeur train 5, adjustable being installed in the frame of described guiding device preferred heights are laid in guiding on the guiding device (not shown) in frame.The hypomere 20u of the first carded web pilot tape 20 be can adjust in this way and balladeur train conveyer belt 14 and the epimere 14o of cover tape 23 and the distance between the 23o laid.
Above-mentioned in order to adjust with 14,23 hypomere and the distance between the exit conveyor 2, should make exit conveyor 2 in the adjustable height of leaving office on 1.
Because, such as will be described later, according to the direction of motion of laying balladeur train 5 height of rotaring forward roller 15 and 24 is adjusted, therefore installation adjusting device (not shown) in frame 3, it optionally drives the driver (not shown) that links to each other with 24 with rotaring forward roller 15 or link to each other with the movable framework of supporting deflector roll, thereby by laying the current height that the current position of balladeur train 5 and the direction of motion determine rotaring forward roller 15 and 24.These devices can for example be designed to pneumatic means.Each rotaring forward roller 15 and 24 also can be bearing in respectively on the turning arm, each turning arm is supported on in 14 and 23 spaces that surrounded, and be subjected to being anchored at the effect of laying the tension spring in the balladeur train 5 respectively, or also can only be subjected to carrying the effect of 14 and 23 pulling force.The pulling force of spring or band is with the position of rotaring forward roller 15 and 24 ends fixed thereon or lower end, and described upper end or lower end position become stable position thus, and the centre position is unsettled, this means that regulator only changes height.Once you begin change, then remaining motion is finished automatically.
The carded web 11 that is fed to this fleece-laying apparatus is finished following stroke at machine intimate: supplying with the following rotaring forward roller 9 that always is transported to fixing carded web inlet on the carded web inlet conveyer belt 6 of carded web 11, can it be stabilized in by guiding device 10 on the carded web inlet conveyer belt 6 at this place, described guiding device 10 is fixed-site but self is mobilizable, and is just flexible.Following rotaring forward roller 9 by the carded web inlet is sent to carded web on the last balladeur train conveyer belt 20 of balladeur train 4 subsequently.Carded web 11 is from these first and second deflector roll 18 and 19 operations towards the formation gap of last balladeur train 4, and the bottom side of described carded web 11 is covered by the last balladeur train conveyer belt 20 of last balladeur train 4, and its top side is covered by carded web inlet conveyer belt 6.Carded web inlet conveyer belt 6 separates with carded web 11 at this place, and operation is through the 4th rotaring forward roller 22, again join in second rotaring forward roller, 19 places and the carded web 11 that constitute the gap subsequently, by last balladeur train conveyer belt 20 carded web 11 is sent in the gap between first and second rotaring forward roller 18 and 19 of balladeur train 4.After leaving this gap, carded web 11 arrives the epimere 14o that lays balladeur train conveyer belt 14.On this conveyer belt, carded web is sent to around lay deflector roll 12 and 13 with in the laying gap between 14 and 23.At first rotaring forward roller 18 of last balladeur train 4 and lay on first stroke of laying between the deflector roll 12 of balladeur train 5, the hypomere 20u of last balladeur train conveyer belt 20 accompanies with it at the upside of carded web 11.After leaving the laying gap, carded web 11 arrives exit conveyors 2.
In the operating process of this embodiment of fleece-laying apparatus of the present invention, to lay balladeur train 5 and between the edge of exit conveyor 2, move back and forth, this represents with four-headed arrow X in the drawings.When laying balladeur train 5 from the right hand edge position of the exit conveyor shown in the figure 2 during to left movement, last balladeur train 4 is equally to left movement, its speed is half of laying balladeur train 5 movement velocitys, thereby receive the length of the carded web 11 of supplying, just the length in the section between first rotaring forward roller 18 of the following rotaring forward roller 9 of carded web inlet and last balladeur train 4 and first rotaring forward roller 18 and first section of laying between the deflector roll 12 by the motion of carded web inlet conveyer belt 6.After the left hand edge of laying gap arrival exit conveyor 2, the direction of motion is correspondingly reverse.
When laying balladeur train 5 was mobile on the fiber web of having laid, the hypomere 14u that lays balladeur train conveyer belt 14 moved in the speed of laying balladeur train 5 with double along the direction of motion of laying balladeur train 5.For the hypomere 14u that makes band is easy to slide on the fiber web of having laid and avoid dispelling the carded fiber that has been laid on the fiber web, form a tilting zone between the following guiding deflector roll of the rotaring forward roller 15 of laying balladeur train conveyer belt 14 and band separating device 16, this tilting zone forms a gradually narrow gap.When laying balladeur train 5 to left movement, cover tape 23 just be laid on the fiber web of having laid and with fibroreticulate relative velocity be zero.Distance second is laid deflector roll 13 rotaring forward roller 24 farthest, cover tape 23 and is descended as shown in the figure, thereby the whole length of cover tape 23 hypomeres is laid on the fiber web of having laid.Yet, when moving,, thereby make band be easy on the fiber web of having laid, slide and prevent from fiber is dispelled with rotaring forward roller 24 liftings along opposite direction.
Should point out in this respect, by simple more embodiment of the present invention, especially when need not to consider to adopt high laying speed, the unnecessary adjustable height that makes rotaring forward roller 15 and 24.In the case, can not consider to lay the motion of balladeur train 5, keep rotaring forward roller 15 and 24 to be in the position of lifting.
Under low laying speed, cover tape 23 can be shorter than illustrated length.
Use each movable member that drives fleece-laying apparatus shown in deflector roll, tooth sector and the cog belt driving.For example, carded web inlet conveyer belt 6 is driven by electric powered steering deflector roll 28, represents described electric powered steering deflector roll 28 with the circle with two black sectors in the drawings.Last balladeur train 4 is driven by cog belt 29, and cog belt 29 is anchored on the balladeur train 4 and moves through being bearing in driving wheel 30 and the tooth sector 31 in the frame 3.Drive laying balladeur train 5 by similar mode by cog belt 32, described cog belt 32 operations are through being bearing in driving wheel 33 and the tooth sector 34 in the frame.
By the driving that realizes last balladeur train conveyer belt 20 around rotaring forward roller 19 and 22 carded web inlet conveyer belt 6, wherein second rotaring forward roller 19 meshes with first rotaring forward roller 18 of adjacent last balladeur train conveyer belt 20.
Lay balladeur train conveyer belt 14 and cover tape 23 and driven by circulation cog belt 35, this cog belt 35 is crossed tooth sector 36 and the driven wheel 37 that is bearing in the frame 3.Cog belt 35 is meshed with gear 38, and described gear 38 is arranged on to be laid on one of deflector roll 12 and 13.Lay deflector roll 12 and 13 and intermesh, described being meshing with each other makes their reverse rotations each other.
