Description

Combing machine

Technical field

The present invention relates to a kind of combing machine that comprises grip module.

Background technology

Just developed a kind of combing machine in 1845, wherein in order to implement the segregation section mating reaction of separation process detaching roller and combing roller by Heilmann.On rolling up/the 5 edition the 167th to 174 page, the cotton spinning handbook (Handbuch Baumwollspinnerei) second of Otto Johannsen can know, the roller that the fibre bundle that is separated with the segregation section mating reaction by detaching roller (herein for separating the pressurization roller) is delivered to subsequently is right, and it is connected or joins on the fibroreticulate end that has formed herein.This moment, roller was to driving with Pilger motion (Pilgerschrittbewegung (intermittently paces motion)).That is, with the tow transport of new taking-up to roller to before, this roller is to driving on opposite rotation direction, a part amount is back carried in the fibroreticulate end that has wherein formed on against the throughput direction of reality.In case this process finishes, the leading section of new fibre bundle just is placed into or overlaps onto on the end that fibroreticulate quilt back carries by (roof tile type ground).During right ensuing the travelling forward of roller, this overlapping region enter into roller right clamp together line, carry out fibre bundle thus with the bonding of fibroreticulate end or engage.A kind of similar device is also in the example of Fig. 7 a-Fig. 7 b from US-PS724119 and know from CH-PS150873.Other open source literature DE-PS243062 has shown a kind of device, wherein arranges that an additional roller is right between detaching roller and the joint roller with Pilger motion driving, and this roller is to driving with identical rotation direction.Compare with the technical scheme of front thus and should realize the raising of performance by the prolongation fetch cycle.

It is right all to be provided with a roller in above-mentioned known organization plan in all cases, this roller to for carry out new fibre bundle on the fibroreticulate rearward end that has formed bonding operation and implement the Pilger motion.This requires the transmission mechanism of corresponding complexity or the drive unit of complexity on the one hand, has limited the size of the combing circulation that will reach thus on the other hand.

In addition, in these organization plans, the leading section of the fibre bundle of taking-up must be deflected in each case so that the roller that passes to subsequently is right.That is the removing direction of fibre bundle is not with right throughput direction is identical sensing and crossing mutually under an angle towards clamping together dotted line roller subsequently.This variation of throughput direction equally also constitutes a factor that limits the size of possible combing circulation.

Summary of the invention

Therefore the purpose of the present invention's setting is, for the coefficient detaching roller of segregation section according to " Heilmann principle " and combing roller is provided with the fibroreticulate device of being used to form of a kind of relative configurations, it has been eliminated aforementioned disadvantages and can improve the combing loop number.Should guarantee that according to device of the present invention the discharge of the component that combing is come out can not influence fibroreticulate formation in addition.

This task solves in this wise, wherein suggestion, on material flow direction, see, the mechanism of at least one adjustable ground supporting is being set after then detaching roller, and it is used to control separated fibre bundle to the transmission of the fibroreticulate device of formation be used to control by the discharge of the component of combing to the sucking-off passage.

But the baffler that this mechanism can preferably be arranged by deflection ground constitutes, and the latter is connected with actuating device.

For feasible component by the combing sector combing turns on the direction of sucking-off passage reliably, suggestion designs the free-ended length of baffler in this wise, makes baffler have a kind of outstanding size a on this operating position.The friendship section of free end by a baffler and a tangent line that is baffler extended size a, and this tangent line extends by the segregation section clamp joint point of detaching roller and combing roller.Guarantee thus, can not arrived in the arrangement zone that forms fibroreticulate device by the material of combing.

Synchronous for the adjusting and the combing circulation that make baffler by actuating device, advise that this actuating device is connected with a control module.

In order not have to form fiber web under the Pilger motion conditions continuously, suggestion, be used to form the mechanism of going in ring that fibroreticulate device has rotatably support, this mechanism is provided with the inner chamber of the aperture that is used for air duct and this mechanism on the circumference at it on its side face at least one subregion is connected with negative pressure source and is provided with case, this case forms one at detaching roller in the discharging area of the fibre bundle that takes out, the space that is spaced with respect to environment between the mechanism that the envelope of combing roller circle and side face go in ring, wherein this space that is spaced subregion is by the side face of this mechanism, by the circumferential area of detaching roller, the subregion of the envelope of combing roller circle and form by deflectable baffler.

Utilize this device can during fibre bundle being passed to the fibroreticulate device of formation, keep the material flow path direction of the fibre bundle of taking-up basically.The mechanism of going in ring can be arranged in the distance at a distance of very little of the envelope circle of combing roller last this moment, and can not make that fibroreticulate formation is subjected to exporting by the damage of the component of combing (staple fibre, shell part, other foul or the like).This is to guarantee by the adjustable mechanism that correspondingly regulates according to setting of the present invention.

The fibre bundle that takes out is in the below of detaching roller and on the material flow path direction to the transmission point that forms fibroreticulate device this moment, and the latter is definite by the outbound course from the fibre bundle of the clamp joint point between segregation section and the detaching roller.That is outbound course begins along tangentially extending towards segregation section from clamp joint point.

By claimed adjustable mechanism; for example form is adjustable baffler; can during carding operation, separate basically with by the material stream of the material of combing by the transmission point of the fibroreticulate device of near formation, so that this material is directionally flowed to sucking-off passage in combing roller arranged beneath.This moment is most of by the component of combing, as for example staple fibre, is between the cloth tooth of band tooth cloth of combing roller.These components are removed and are discharged to the sucking-off passage from the brush roll in the rotation of combing roller arranged beneath then.A part is also come out from the zone of card clothing by centrifugal force by the material of combing and is carried downwards under the effect of the suction airstream that produces by suction channel in the outside zone of the envelope circle of combing sector.For these components can not entered in the zone that forms fibroreticulate device, used adjustable baffler as director element, this director element guarantees the transmission of determining to the sucking-off passage.

Advise in addition within the mechanism of going in ring, at least one second mechanism being set, can be by this mechanism at least by on the time interval, synchronously controlling air duct freely with the discharge of fibre bundle at the environment of first mechanism and the part zone in the aperture between the negative pressure source.

By by the negative pressure source negative pressure on the side face that is applied to first mechanism on the correct time point directionally, can correspondingly keep the fibre bundle that is discharged from and then under the orientation of the lap of hope and the little hook portion that stays, be placed on the fibroreticulate end.

Preferably second mechanism of the first in-house suggestion be connected with drive unit and circumference at it on be furnished with at least one aperture, this aperture is extended on the width of the fibre bundle that takes out greatly and is based upon the air duct of first mechanism and the connection between the negative pressure source by this aperture.Second mechanism is at this moment as a kind of control element, is used for being connected between the aperture of first mechanism and negative pressure source.Described synchronous in order to guarantee, the drive unit of second mechanism is connected drivingly with the drive unit of withdrawing device.

For corresponding zone is separated with respect to negative pressure source reliably, also suggestion is additionally at first in-house at least one cap member that is provided with.

Preferred first mechanism is made of the screen cylinder of rotatably support, the cylinder in this screen cylinder internal placement second mechanism as rotatably support.

Can stipulate that in the case according to applicable cases, the rotating speed of first or second mechanism can be controlled or regulate.Especially can influence joint by the rotating speed that changes first mechanism and connect (joint connection distance

).

Also it is contemplated that in addition, change the direction of rotation of first or second mechanism.This moment, the direction of rotation of two mechanisms also can be reverse mutually.

Advise in second mechanism, settling one or more cap members in addition.This lid mechanism for example is arranged in the zone that the fiber web that forms in first mechanism must be removed, so that carry the continuation of carrying out subsequently to handle.

For the fiber web that guarantees to have formed on the circumference attached to screen cylinder between period of output, suggestion is provided with other aperture with distributing on the circumference of second mechanism, its width with respect to the fibre bundle of taking-up just extends on a part of zone.On the side face of screen cylinder, form a little negative pressure thus constantly, set up in its gap between screen cylinder and roller, because this gap is connected with negative pressure source constantly.But the effect of this little negative pressure does not have to influence and only be used to as already described make fiber web remain on screen cylinder from the transmission of separator to screen cylinder to fibre bundle.In order to influence air flow in the space that is spaced definitely with target effectively, suggestion is provided with at least one adjustable element in the zone of case, it is applicable to controls at least one aperture that is used for the air duct between the surrounding air of space that is spaced and case.Can stipulate that adjustable element is connected with deflectable baffler combination or with it this moment, so that control material stream.

This element also can be made of baffler independent, that can center on a yawing axis deflection, and it is seen on fibroreticulate throughput direction, extends on the length of detaching roller basically.

This moment is suggestion advantageously, and the yawing axis of baffler is arranged in the zone of detaching roller below and the free end of baffler points on the direction of detaching roller.

In order to guarantee that fibre bundle is placed on the screen cylinder reliably, baffler is settled in suggestion in this wise, makes the free end of baffler form clamp joint point with first mechanism on the position of opening.

Preferred other deflectable baffler is adjacent to layout with the baffler that this is used to control material stream.

For the air flow butt joint operation that forms in the sucking-off passage by negative pressure is not had a negative impact, suggestion is provided with at least one aperture in the zone of sucking-off passage, it is connected the sucking-off passage and is provided for opening and changing in combing cycle period the mechanism in aperture with surrounding air.Owing to the required volume of air subsequently of negative pressure in the sucking-off passage sucks from surrounding air by additional aperture, the only very little air flow that produces owing to the negative pressure that applies in the sucking-off passage is present in the discharging area of fibre bundle thus thus.Be that the joint operation can not be adversely affected owing to the negative pressure that applies in the sucking-off passage.The mechanism that is used to open and close this aperture can be that independent mechanism that can control or suggestion is connected with deflectable baffler.

Have outer surface 21 at the segregation section 20 that on certain circumference angle, extends on the combing roller 16, for separation process (Fig. 3), this outer surface and detaching roller 24 mating reactions that on the direction of combing roller shaft 7, are bearing in movably in the frame.Fixing comb 8 is installed between clamp 1 and detaching roller 24, and it is bearing between clamp 1 and the detaching roller 24 movably by the drive unit 9 that schematically illustrates.Drive unit is connected with controlling organization ST by circuit 23 for 9 this moments.

The guide 10 that but deflection ground is installed in clamp 1 is thereon on the side and have spigot surface 15 on the side facing to pincers cutter 3, guiding fleeces W on spigot surface.Guide 10 has inflexion point U in the zone of pincers cutter 3, and fleeces is by the direction upper deflecting at clamp joint point KZ herein.With certain distance of this spigot surface 15 on, director element 14 has been installed in the zone of inflexion point U.Director element 14 is fixedlyed connected with guide 10.Distance between the downside of spigot surface 15 and director element 14 designs at this moment in this wise, makes fleeces W can be conducted through the free space that exist this moment.

In the zone of the envelope of combing roller 16 circle HK and below detaching roller 24, be furnished with and form fibroreticulate device 30.This device 30 separates with respect to surrounding air by case 31 at least in part.Discharging area AB and surrounding air that this case especially is used in the fibre bundle that will take out separate.Rotatably support screen cylinder 33 in this case.Cylinder 35 is rotatably supported in inside coaxially with screen cylinder 33, two aperture S1 is set on the circumference of this cylinder with distributing, and S2 is by the air circulation of this aperture control by screen cylinder.This moment, the inner chamber IR of screen cylinder 33 or cylinder 35 was connected with negative pressure source 38, and wherein in order to control this valve 39 that is connected with, it is connected with controlling organization ST by circuit 40.Additionally be furnished with hard-wired cap member 42 in the inner chamber of cylinder 35, it especially makes cylinder 35 inner chambers that are under the negative pressure separate with respect to external environment condition in the zone of carrying device 44.This discharges by the periphery of carrying device from screen cylinder 33 in particular for assisting fiber web V.Carrying device 44 for example comprises two coefficient roller W1, W2, and they are transported to fiber web funnel VT with the fiber web V that sends, and form ribbon F in this fiber web funnel.This ribbon F (also combing machine sliver) for example is sent that platen T goes up and flows to subsequently drafter with other ribbon of adjacent combing head.

Baffler 46 is installed in the envelope circle HK of combing roller 16 with can centering on rotating shaft 47 deflections and installs between 30.Rotating shaft is bearing in the frame for 47 this moments regularly.As described in also wanting as the back, the task of baffler 46 is the directions that influence fabaric mterial flow.

Go up in the position shown in the figure 1, the fiber coma FB that protrudes in the clamp joint point KZ of closed clamp 1 with length L is in the inside of the cloth of combing sector 19.The all fibres and the component that are equal to or less than length L are in this case come out from fiber coma FB combing by combing sector 19.Fixing comb 8 disengaging engagements and detaching roller 24 promote with the envelope circle HK of certain amount from combing roller 16 during combing.Baffler 46 is in an inflection point on combing position shown in Figure 1, and its free end is near the circumference of screen cylinder 33 on this inflection point.Arrange another baffler 26 abreast with baffler 46, it can be around the rotating shaft 27 deflections hinged installation in ground.Baffler 46 is connected by connector 28 with 26.Also deflection together of baffler 26 when baffler 46 deflections thus.Also it is contemplated that a solution, wherein baffler 26 moves by independent drive unit and baffler 46 mutually independently around rotating shaft 27.Between two bafflers, there is not connector 28 in this case.The function that also will describe in the back of baffler 26 can be combined to correspondingly baffler 46 neutralizations of structure in addition and remove additional baffler 26.Equally also can adopt in a kind of scheme shown in the partial view of Fig. 5 b.This moment, baffler 26 also was connected with baffler 46 by connector 28, but did not have the yawing axis of oneself.Be baffler 26 centers on rotating shaft 47 by baffler 46 and connector 28 deflection.Can be known by Fig. 5 b in addition and see that baffler 46 is connected with another short baffler 56, the latter extends downwards on a relative side of rotating shaft 47.Shown in the position on baffler 56 be positioned on the sidewall 53 of sucking-off passage 52.Promptly at sidewall 53 and baffler 56, or there is closed face between the baffler 46.

As schematically expression, the adjusting of baffler 46 is implemented by the actuated piece 49 that acts on the yawing axis 47.This moment, actuated piece 49 was connected with controlling organization ST by circuit 50.Baffler 46 will form fibroreticulate device 30 and be separated by the material stream of the component of combing on this position.This material stream (representing by arrow), it can be between the cloth tooth of combing sector 19 on the one hand and also can be in envelope circle HK outside, is flowed to sucking-off passage 52 downwards.By knowing among Fig. 5 b, the Design of length of baffler 46 becomes to make its free end to protrude in tangent line C with the yardstick of amount a on this outside inflection point as equally.Tangent line C extends in the direction of screen cylinder 33 from the clamp joint point KA of detaching roller 24 at this moment.Guaranteed that by overhang (under detaching roller is raised situation) deflects on the direction of sucking-off passage 52 reliably by the material of combing sector combing with yardstick a.The sucking-off passage is connected with a negative pressure source that does not illustrate for 52 this moments.Cleaning brush 36 can support rotationally around rotating shaft 34 in this sucking-off passage 52, and this cleaning brush is used to clean the combing sector 19 of combing roller 16.This moment, the bristle 37 of cleaning brush was engaged in the combing sector 19 of combing roller.

Separated component (as for example staple fibre, cotton knot, the shell part, dust, or the like) be transported in the central processing unit by the conveyer that does not illustrate.

The fiber coma comes out from combing sector 19 and enters the F2 of intermediate space freely between combing sector 19 and the segregation section 20 after then carding process.When arriving this position, clamp 1 is opened by lifting clamps cutter 3.Simultaneously guide 10 upward deflects and moves away nipper plate 2 with its inflexion point U around yawing axis 12.Also deflection together of director element 14 in this case.Detaching roller 24 moves on the direction of the envelope circle HK of combing roller 16 abreast therewith.By within clamp 1, promoting guide 10, prolonged in the highway section of supplying with between roller 5 and the clamp joint point KZ that thereon fleeces W is guided in clamp inside.Because it is static supplying with roller 5 in this time period of combing circulation, fiber coma FB outstanding from clamp shortens length L 1.The original length L that is fiber coma FB has shortened an amount, and the guiding stroke in clamp 1 prolongs with this amount.In case combing sector 19 is by baffler 46, the latter just justifies the direction upper deflecting of HK and occupy a terminal position then during separation process at the envelope of combing roller 16, and this position is for example shown in Figure 2.

On position shown in Figure 2, the zone neutralization that segregation section 20 has been positioned at detaching roller 24 therewith is formed for the clamp joint point KA of fleeces W end.Guide 10 is in the position of its top now.The end that protrudes in clamp joint point KA of fiber coma FB has for implementing the needed length L x of separation process on this position.

By between clamp joint point KA by the fleeces of combing, detaching roller 24 is placed by driven segregation section 20 by frictional force and rotatablely moves.But it is contemplated that also additional independent drive unit is set is used for detaching roller 24.

As from knowing Fig. 2, by deflection guide 10, the end that protrudes in the clamp 1 of fiber coma FB also is raised.By described lifting, fiber coma FB is transferred in the sphere of action of the card clothing 8a that fixes comb 8.

Begin separation process now to the fiber that obtains from clamp joint point KA from this position.To supply with roller 5 by the device that is not shown specifically again simultaneously and place and rotatablely move, so that a new fleeces spare is supplied with clamp 1.This supply operates in this case and supports by taking out operation.When supplying with operation and during, fixing comb 8 moves on the direction of detaching roller 24 by drive unit 9, has reached in the position shown in Fig. 3 up to it, this moment, it was positioned at the circumference part near detaching roller 24.This shift motion of fixing comb is approximately corresponding to by supplying with the amount of feeding of the fleeces that roller 5 follows.Prevent contingent clogged with material in the zone of fixing comb back thus.By promoting the fleeces ends, guarantee fixing comb 8, or its card clothing 8a is in the enough big degree of depth of thrusting that always has during the separation process in fibrous material by guide 10.By the supply during separation process, but realized and similar situation under the situation of conventional combing machine with the grip module that supports on deflection ground.That is, fleeces W is fed to clamp joint point KA continuously with this amount of feeding, thus with conventional machine in the same, can realize a kind of fibre bundle of thin and elongation, be used for subsequently attended operation with the fiber web V that has formed on screen cylinder 33.This attended operation (joint operation) for example is shown specifically in Fig. 3 and 4.As being known by Fig. 3, by rotatablely moving of cylinder 35, aperture S2 is in cap member 42 tops and produces the air flow that passes through screen cylinder 33 by the negative pressure that applies in the cylinder 35, as it is represented by arrow.Thus, the terminal FE that enters the fiber bundle F P of the taking-up in screen cylinder 33 zones is attracted on the circumference of screen cylinder 33.The guiding that supported air by the aperture that discharges between baffler 26 and screen cylinder 33 54 this moment.Promptly the air from surrounding air to discharging area AB is supplied with and can be controlled by deflectable baffler 26.

In case the terminal E of another of fiber bundle F P discharges (Fig. 4) by clamp joint point KA, it just is placed in as chain-dotted line is represented on the terminal VE of the fiber web V that has formed.This supports by the air flow that changes in the zone of screen cylinder, this air flow by cylinder 35 be rotated further or its aperture S2 forms.Be placed into by the terminal E with fiber bundle F P on the terminal VE of fiber web V, form a kind of overlapping region of roof tile type, it generally is also referred to as tap points.

In order before forming this tap points, the terminal FE of fiber bundle F P to be rotated further on the shell 33a that remains on screen cylinder 33 under the S2 situation of aperture reliably, by make at the actuated piece shown in Fig. 1 49 baffler 46 and thus and baffler 26 at the direction upper deflecting of the shell 33a of screen cylinder 33.The terminal FE of fiber bundle F P that formerly is placed to thus on the screen cylinder 33 goes up slight chucking power of generation.The out of Memory of the relevant attended operation in this organization plan for example can obtain from disclosed WO2006/012758.Organization plan shown in the replacement also can be provided with a kind of baffler 26 that can move independently with baffler 46.

But reaching baffler 46 shown in Figure 4, or before the terminal position of 26 outside, baffler 46 has passed through the centre position, as for example as shown in Fig. 5 a.Can see this moment between the sidewall 53 of short baffler part 56 and sucking-off passage 52, also having an aperture 58.Prevent from discharging area AB, to produce the air flow that disturbs the joint operation in sucking-off passage 52 by this aperture 58 by the air flow that the negative pressure that applies produces.That is, the volume of air major part that is needed by the negative pressure in the sucking-off passage sucks from surrounding air by aperture 58.One minimum part (shown in the arrow of drawing by a dotted line) also sucks from discharging area AB.Do not produce the air flow of the terminal E of the fiber bundle F P that any interference discharges but this part is considerably less.If aperture 58 is not set, the terminal E that fibre bundle may take place so is owing to being wound on the end of baffler 46 at the air flow on the direction of sucking-off passage 52.Under certain situation, this may disturb or influence suction via the regulation of 33 couples of terminal E of screen cylinder unfriendly.But, aperture 58 avoided this incorrect air flow by being set.

The zone neutralization that the fiber web V that forms is transferred to carrying device 44 by rotatablely moving of screen cylinder 33 there by roller to W1, W2 sends.For the fiber web that make to form remains on the screen cylinder 33 to the path of carrying device reliably at it, on the circumference of cylinder 35, be provided with microstome K (referring to Fig. 1) with distributing, they are connected with inner chamber IR under being in negative pressure.Between the shell of cylinder 35 and screen cylinder, produce a little negative pressure enduringly thus.This guarantees that fiber web remains adhered on the shell of screen cylinder.The fiber web of discharging is fed to fiber web funnel VT, and fiber web assembles ribbon F in this fiber web funnel.As already described, ribbon flows to subsequently drafter with other ribbon then on guiding platen T, continue processing.

After finishing the operation of separation and joint, guide 10 deflects into lower position shown in Figure 1 again by actuating mechanism 11 under the effect of controlling organization ST.But before beginning this deflection, detaching roller 24 must raise up from the envelope circle HK of combing roller 16.Baffler 46 has been on the drawn position of Fig. 4, this position be for the carding process that carries out subsequently needed.In case guide 10 is in the position that its below changes over to again, clamp just is closed and makes fixing comb to move and turns back to position shown in Figure 1.During the process in the position below guide 10 deflects into, the guiding stroke of fleeces W in clamp 1 shortens again, increases from the length of the outstanding fiber coma FB of clamp this moment thus.Therefore exist a fiber coma FB with length L to be used for subsequently carding process again, as shown in Figure 1.

Shown in the utilization and the organization plan of describing, under fixing clamp situation,, wherein fix the combing work of combing and also implemented completely for separating and carding process provides a kind of geometry situation of the best.This also allows to carry out work with high combing period, and this is impossible when adopting original Heilmann structure.Deflectable in addition baffler guarantees, material stream can obtain directed guiding in carding process and in separation process, this moment, the change or the commutation of the removing direction of fibrous material in separation process was essential, so that the fibre bundle that takes out is passed to subsequently the fibroreticulate device of formation.This equally also can realize carrying out work with high combing period.

Also it is contemplated that with using in combination and be different from as directed other the fibroreticulate device of formation according to guiding mechanism shown in the present.
