Resultant sliver from the heads is combined (3) and deposited in a can (BA). Individual controllers (P1 to P16) and associated sensors allow each head to be individually decoupled for servicing without stopping production on the rest of the machine. An independent claim is included for the process of operating a comber with multiple combing heads (X1 to X16) in which the drive (A) to the various elements on each head can be individually controlled.

Description

The drive controlling that is used for combing machine

Technical field

The present invention relates to a kind of combing machine, it comprises that a plurality of combing unit and at least one are used for the drive unit of combing unit, this drive unit is connected with control module, wherein, the fibrous material that is supplied to independent combing unit is combed and processes and make up and form sliver, formed sliver is sent to the drafting system of the back that has adjacent sliver apparatus for placing, and each combing unit has at least one monitoring element.

Background technology

The actual now combing machine that uses generally has eight combing heads of being arranged to a row adjacent to each other, and each combing head has been provided the lap roller that is used for combing processing.The nonwoven combination of being processed and sending out by independent combing head combing forms sliver by known devices, and is supplied to next drafting system on the direction that the material transverse to the combing head on the guide table flows.Then, the sliver that forms in drafting system utilizes the funnel wheel of ring form to put into storage tank in the sliver apparatus for placing.This class combing machine comes work with the combing circumferential speed up to 400KS/min now.In this class combing machine, drive unit is designed so that all combing heads all utilize drive unit and interconnect rigidly, and this drive unit is realized by public driver element.This driver element is positioned at an end of combing machine, and comprises the gear mechanism that is driven by main motor.This main motor is controlled by centralized control unit.Sensor is located on the independent combing head, and for example is used to monitor the quality that is sent to sliver herein.In case one of them sensor that is communicated with centralized control unit sends error signal to this control module, so just stops the driving of whole combing heads or whole combing machine.The result who obtains like this is that at first, the fault that produces error signal at the combing head place must be eliminated before combing machine is devoted oneself to work again.This just causes having increased operator's monitoring, and if elimination in time of fault, can cause the decline of cotton mill output.

In order to increase combing circumferential speed and the final productivity ratio that increases, CH-PS 681309 has proposed a kind of combing machine, wherein, what replace known combing head is, used so-called combing unit, it is mounted with the lap sheet from lap, is used for the sliver that combing processes but be provided with at least one.This sliver can be supplied to the combing unit from the storage tank that is arranged in independent below, combing unit.The sliver that processes that is combed that is transmitted by independent combing unit combines on the feeding platform, and is supplied to next drafting system.This drafting system can be provided with adjusting device.Utilize this adjusting device, just can reduce combing element (clamp, circle comb, detaching roller etc.) significantly,, and can under much higher combing circumferential speed, drive therefore with regard to because of need lower quality being quickened.

In the combing machine that reality is used, the lap sheet of about 80ktex (g/m) is supplied to each and is used for the combing head that combing goes out.The sliver that forms on the drawing-off framework has the quality of 5ktex.If there are two slivers to be supplied to the combing unit described in the CH ' 309 respectively, so that realize the productivity ratio identical with traditional combing machine, when eight combing unit were also used in supposition, they just must be worked under the combing circumferential speed of 3200KS/min so.High combing circumferential speed like this is infeasible from present viewpoint from mechanical load and combing process technology aspect.Therefore, just propose to adopt the combing unit (for example ten or 12) of bigger quantity to realize feasible combing circumferential speed, be at present to boost productivity.In addition, also propose and to be supplied to independent combing unit up to four slivers.For example, when using 12 such combing unit, they are mounted with the sliver of four 5ktex separately, if the combing unit moves under the combing circumferential speed of 1070KS/min, just can realize the productivity ratio identical with traditional combing machine.Whether the device shown in the utilization can realize still question mark technically.If will further boost productivity as required, so just must adopt higher combing circumferential speed.

In order to drive the combing unit described in CH ' 309 examples, for each combing unit provides independent Motor Drive, wherein, two adjacent combing unit also can be driven by common motor.This is the comparison costliness, and needs the control corresponding device to come to determine simultaneously with each other independent motor.Also further propose in CH ' 309, independent combing unit should be assigned common control device, and it can utilize the conditioning signal of adjusting segmentation mentioned herein to control.Do not introduce and how to carry out this control.

In CH ' 309, purpose is to propose littler combing unit, and it allows to use higher combing circumferential speed because of littler quality, therefore just allows to realize higher productivity ratio.In order to realize such output, in this case, also must increase the quantity of at present known combing head.In this case, in the design that is proposed, suppose that all combing unit are always in work, to realize required output.

Summary of the invention

On workbench T, the sliver B that is formed at independent combing head K1-K8 place is guided to drafting system S.Especially as shown in Figure 3, workbench T guides sliver B with being inclined upwardly.The guide plate that does not demonstrate in detail that is used for this purposes is provided in this zone.The drafting system S that comprises a plurality of drawing rollers SW pulls out the fibrous matter of being supplied with, and forms non-woven fabric V, this non-woven fabric V is made up forms sliver 3 by following suitable guiding device (not shown) in drafting system S after then.By guide or the conveyer 4 (for example conveyer belt) that schematically shows out sliver 3 is sent on the driven calendering roller KW then, described sliver is sent to the funnel wheel TR of rotation by this calendering roller device.Afterwards, funnel wheel TR is in place the sliver 3 that is received in the storage tank K of funnel wheel below with the ring form.Simultaneously, storage tank K carries out extra rotatablely moving.

Fig. 2 has shown the longitudinal axis 6 that is used to drive drafting system S and sliver apparatus for placing BA, as shown shown in the meaning property.From EP-PS 640704 for example, can obtain detailed description to this drive unit.

Fig. 3 and Fig. 4 have shown an exemplary embodiments that has control system according to of the present invention.In this case, shown in the embodiment of Fig. 1, provide sliver apparatus for placing BA, wherein, utilized the non-woven fabric V combination that drawing rollers SW forms by drafting system and form sliver 3.This sliver 3 is sent to funnel wheel by a pair of calendering roller KW then, utilizes this funnel wheel TR that sliver 3 is placed among the storage tank K with the ring form.

Compare with the combing machine of Fig. 1, in Fig. 3 and exemplary embodiment shown in Figure 4, for example, provide independent combing unit X1 to X16, it and is connected on the support frame 8 directly adjacent to each other.This support frame 8 is supported with the framework 29 that is positioned at the sliver apparatus for placing BA on the O of ground by driver element A in this case.

But the combing unit is called after combing box also, wherein, actual combing element such as clamp 10, circle comb 11, detaching roller, cleaning brush 13 or the like and be installed among the corresponding combing unit X1 to X16 by suitable element, this can analyze from the enlarged side view of Fig. 6 and draw.The combing element have will be narrower than the width of the shell 16 of corresponding X1 to X16 length dimension.Clamp 10 is mounted to pivotally around circle comb axle 15, and is driven to and fro via leverage 19 or move by driven shaft 14.

In the example shown, the fixed mechanism 18 that combing unit X1 to X16 utilizes Fig. 6 to be schematically shown is connected on the support frame 8, so that when mounted, they have the free space FR that O overhead has a spacer segment FA.Flat storage tank F1 to F32 for example is arranged in this free space FR and is in the below of combing unit X1 to X16, is used for that sliver that combing processes utilizes suitable guide mechanism and from combing unit that described flat storage tank is supplied to separately to be distributed.For this reason, as shown in Figure 6, paired roller 20,21,22 be connected support frame 8 or combing unit originally on one's body so that the feeding roller 9. that sliver Z1 or Z2 are supplied to clamp 10 is in the example depicted in fig. 6, have for example two sliver Z1 of 10ktex fiber quality, Z2 extracts out from storage tank F1 and F1, and is supplied to combing unit X1.

Schematically shown in Figure 6, conduit 17 is in the below of cleaning brush 13, and the composition that combing goes out (for example being also referred to as the staple fibre of noil) can be sucked out to unshowned central separator via this conduit 17.In this case, conduit is under the negative pressure, and has corresponding opening (not shown) and accept and separate any composition that separates downwards.Also can have such embodiment, its middle frame 8 is provided with corresponding opening, and separates the separately conduit of composition with acting on.

Actual combing process in each combing unit is general known, therefore here is not described in detail.In addition, for example in document " textile college-combing and drawing-off practical guide-1987 year ISBN 0 900,739 93 2 ", be described in detail.Yet, the embodiment of the combing device shown in the present invention is not limited to, the embodiment of other combing element and ensuing sliver forming element also is fine.For example, such combing device also is feasible, wherein, and from separating the device that sliver is shaped that is used for that fibrous material that cylinder takes off is sent to next continued operation.

Material flow path direction MF in each combing unit X1 to X16 is aiming on the direction of D transverse to formed combing machine sliver B (referring to short " sliver ") supplier, and this sliver is supplied on the next drafting system S.The sliver B that forms on independent combing unit X1 to X16 is placed on the driven conveyer belt FB by guided plate 31, the sliver funnel that is not shown specifically and a pair of roller 32, and sliver B is sent on the drawing rollers SW of next drafting system S by this conveyer belt FB.For example can utilize at the known deflecting element described in the EP-PS 349866, sliver B is deflected on the direction of transfer D.Sensor N is arranged in the zone of guided plate 31 or in the zone of a pair of roller 32 of each combing unit, and is used to monitor the quality of the sliver B that is transmitted, and its signal transfers to central control unit via lead 34.This visible EP-PS 339300 of an example that is used to monitor the sensor of fiber quality.

Conveyer belt FB utilizes the driving connector 26 that schematically shows out and is connected on the transmission device of driver element A, and is driven from here on.Conveyer belt FB at one end is installed on the framework 28 of driver element A by unshowned well known elements, and is installed at the other end on the framework 29 of sliver apparatus for placing BA.The other support roller or the support member 24 that are used for conveyer belt FB can be located between two supporting-points, as shown in Figure 6.

Independent combing unit X1 to X16 for example drives by one or more longitudinal axis W.For the purpose of clear, only shown an axle W.Be connected coupling P1 to P16 on the control module ST is used for switching between the element of axle W and independent combing unit X1-X16 to be driven via connecting line 36.That is to say that control module ST can control independent coupling P1 to P16 individually by line 36, and utilize the driving schematically show to connect 5 to connect or interrupt being connected of independent coupling P1 to P16 and driver element A by means of axle W.Driver element A is connected on the control module by line 35.Be connected providing between sliver apparatus for placing BA or drafting system S and the control module ST by the line 33 that schematically shows.Basically from sensor transmissions to control module ST, it is connected in the zone of sliver apparatus for placing BA or drafting system S by this connection to connect signal.These are the monitoring sensors that are used for material monitoring and machine function.In case one of them sensor N transfers to control module ST with error signal (for example the sliver quality is too little) via line 34, the driving of so corresponding combing unit just is stopped by triggering corresponding connection element P.Simultaneously, control module produces video or audio signal and (is positioned at signal lamp on the machine or the display screen on the watch-dog; Signal tone or the like), indicate operator's combing unit to break down or stop.

Yet, to compare with nowadays known combing machine, remaining combing unit continues to produce and can not shut down.In this case, under the situation of 16 combing unit that are adjacent to operate, just lose 1/16 of the fiber quality that is supplied to next drafting system S.If this drafting system S is provided with adjusting device, this incorrect amount of recoverable fiber quality in drafting process so.Therefore, compare with existing combing machine, can breaks in production, wherein, the transmission point at the combing head place occurs under the situation of fault, and whole combing machine is at once by control device and transfixion.In an embodiment according to the present invention, operator even can plan suitable elimination fault.When the operator must operate sizable machine part in the nowadays common cotton mill, this was especially favourable.

In the example of Fig. 6, shown that another drives modification, the element that wherein is arranged for the supply material is driven by dedicated drive unit ME as supplying with roller 9 and roller 20,21,22.This driver element ME for example can comprise one or more independent electric drivers, and it is directly installed on independent place, combing unit, and can control via line 37 by control module ST.The axle of all the other elements such as clamp axle 44, circle comb axle 15, brush 13, detaching roller 12 and transmit roller 32 drived unit A and utilize one or more connector P to drive via axle W and driving connector 5a to 5e.Connector P is connected on the control module ST via line 39.This driver element A is connected on the control module via line 35.

Except described independent electric drive unit ME, special-purpose mechanical gear mechanism also can be provided, be used to drive the said elements that is used to supply material, these elements utilize the corresponding driving connector and are connected on the driver element A.

If one of them sensor N transfers to control module ST via line 34 with error signal, the driver element ME of so relevant combing unit just is stopped via line 37.Therefore the supply that sliver Z1 and Z2 is supplied to clamp 10 is interrupted, and the combing processing technology of this combing unit also will be interrupted.Clamp 10, circle comb 11 and separates cylinder 12 and further be connected on the driver element A, and continuation moves under the state of material not having.As mentioned above, the audio or video signal that utilizes control module ST to produce then to be used for the operator is so that indication fault.Therefore the fault of corresponding combing unit and accurate location thereof can demonstrate on display screen.

When the fault on this combing unit was not operated the person subsequently and cancels, if necessary, other element of still working on this combing unit can utilize coupling P to stop.In this connection, the operator also can utilize control module ST to come the artificially to trigger this stopping.After eliminating the fault cause because of a variety of causes, the operator can utilize the corresponding input block monitor of keyboard (for example with) to reset each combing unit in the running via control module ST.By the described design that independent combing unit is turned off in operator's manual intervention step by step, also can utilize control module ST fully to carry out according to the control program of storage.Controlled stopping process of other of combing unit or the design of the control under the situation that breaks down or when requiring to change storage tank also are feasible, but these are not here described in detail.

In other exemplary embodiment of Fig. 5, shown that another drives design, wherein, 16 combing unit X1 to X16 are arranged to a row, and it is shown as an example, and is driven by two driver element A1 and A2.Be arranged on the group G1 of the driver element A1 driving combing unit X1 to X8 among combing unit X1 to X16 one row.In this case, the driving of driver element A1 connects and is shown by the driving shaft W3 that is schematically shown, and driving shaft W3 correspondingly is connected on the combing unit X1 to X8 with driving connector 5 by the connection element P that is schematically shown.Driver element A1 has the gear mechanism H1 that is schematically shown, and it is driven by at least one motor M1.

Another group G2 drived unit A2 of combing unit X9 to X16 drives, and driver element A2 also has the gear mechanism H2 that is driven by motor M1.Gear mechanism H2 connects to the driving on the independent combing unit X9 to X16 and is shown that by axle W4 axle W4 correspondingly is connected on the combing unit X9 to X16 with driving connector 5 by the connection element P that is schematically shown.As drive unit being divided into two groups of G1, the result of G2, independent driving shaft W3, W4 can keep shorter.By this design, more (for example 24) combing unit that surpasses 16 can also be provided, and can not make drive unit and driving shaft thereof overload.Each organizes G1, the independent combing unit among the G2 as Fig. 3 and embodiment illustrated in fig. 6 in be stopped.By the embodiment that is proposed among Fig. 5, just can stop whole group of G1 or G2 and reach one period short period, so that the module of utilizing control module ST to carry out the storage tank of distributing to this group is changed.Therefore the quality of materials that occurs in short period in drafting system that is caused is not enough must compensate with certain form.For example, can from the container that provides in addition, reach shorter a period of time by the delivery of fibers material.

In addition, Fig. 7 has shown the partial view of combing machine 1, and combing unit X1 to X4 drived unit utilization axle W and connector P shown in it drive.In this case, combing unit X1 to X4 has gear mechanism L1 to L4 separately, gear mechanism L1 to L4 utilize to drive connector 5 and connector P and drive-type be connected on the W.A Wx quilt gear mechanism L1 to L4 separately that is schematically shown of the drive element in each combing unit drives.For example, also can in gear mechanism L1 to L4, use belt drives.Occur at each place, combing unit under the situation of the fault for example discerned by sensor N, corresponding gear mechanism L1 to L4 just is disengaged, and this is as described in the above example, controls via line 36 by control module that connection element realizes.

The module of storage tank F1 to F4 is changed and is schematically shown as Fig. 7.In this module replacing process, in order to follow the tracks of the storage tank of new filling, utilize connector P to be disengaged, thereby combing unit X1 and X2 are stopped by control module ST.This process is carried out by the operator or is started.After changing storage tank and starting new sliver, the operator can pass through at control module ST place input signal, and connects the combing unit that has stopped again.In storage tank replacing process, remaining combing unit can continue operation, has therefore just kept production.As mentioned above, for example, can come the short-term deficiency of compensation fibre quality by the adjusting device at next drafting system S place.Change system if can obtain having the full-automatic storage tank of automatic starting device, so this module is changed and just can fully automatically be carried out.

In Fig. 8, in chart, schematically illustrate the control of combing machine or combing unit.Signal from sensor N is depicted on the vertical axis, has shown eight combing unit here.Axle when horizontal axis is.If sensor N does not provide error signal, the curve value of moving to 8 places just so are for example to time T 0.In time T 1, the sensor N of combing unit sends error signal to control module ST, utilizes this control module ST to control the connector P that distributes to this combing unit, interrupts the drive unit of this combing unit or its part parts at least.Passing through a period of time that operator wherein eliminated fault at interval after the t1, at time T 2 places, corresponding connector P connects by means of control module again by the operator, and the combing unit that stops to drop into operation once more.This curve marches to initial value 8 once more.In time T 3, error signal is sent to control module ST by three sensor N of combing unit.This curve value of moving to 5, it represents tolerable limit TG simultaneously.When reaching this tolerable limit TG (promptly under the situation that three combing unit break down), the deficiency that combing machine no longer can the compensation fibre quality.Therefore, after time T 4 places stopped, remaining combing unit or whole combing machine 1 were just shut down after t3 has been delayed time in the combing unit that breaks down.This also can be by the audio or video signal person that comes the notifying operation.Compare with having only a combing unit, sort signal can higher priority show.

If the combing unit is reparation or beamhouse operation again after time interval t4, combing machine can the person of being operated restart at time T 5 places so.In time T 6, error signal is notified to control module ST by two sensor N.Because the quantity of two error signals is in more than the tolerable limit TG, therefore have only two controlled cell S T in corresponding combing unit to stop, and other combing unit continue to produce.If eliminate after time interval t6 in the source of makeing mistakes of these two inefficacy combing unit, they just can be devoted oneself to work again so, so curve is at the time T 7 places value of increasing to 8 again.
