Description
Technical field
The present invention relates to a kind ofly be placed into method in the ribbon container with export the ribbon that comes by spinning preparation machine by means of the ribbon place apparatus, wherein, described ribbon is transferred to from the output device that is arranged in the spinning preparation machine exit and is positioned at the leading into device (draw-in device) of ribbon place apparatus porch, and therefore is subjected to and leads the influence into the proportional drawing-off of output speed of speed and output device of leading into device.
On the other hand, the present invention relates to a kind of control device that is used for drawing-off, output to the ribbon of ribbon apparatus for placing by spinning preparation machine, experiencing described drawing-off between the device at the output device in spinning preparation machine exit with leading of ribbon place apparatus porch, wherein said drawing-off with lead into leading of device into the output speed of speed and output device proportional.
In addition, the present invention relates to have the weaving unit of spinning preparation machine and ribbon place apparatus, described spinning preparation machine is included in the output device that its exit is used for exporting ribbon, described ribbon place apparatus comprises and is positioned at its porch and is used for drawing-off leading into device by the ribbon of spinning preparation machine output, wherein, ribbon has experienced drawing-off at described output device and described leading between the device, described drawing-off with lead into leading of device into the ratio of the output speed of speed and output device corresponding.
Background technology
For example from a kind of as can be known ribbon place apparatus that is used for carding machine of DE 3734425 with electrical motor driven device.Described ribbon place apparatus is disposed like this, makes that the output speed of the output device be positioned at the outlet of card place is detected and is used to control the leading into speed into device of leading that is positioned at ribbon place apparatus inlet.The drawing-off of caused thus ribbon to be placed can be adjusted in advance.
Practice shows that defective often is to occur in the conventional control procedure of drawing-off of ribbon to be placed, is not that it was exactly low being set too highly in this regional drawing-off, and under these two kinds of situations, defective can cause the ribbon fracture.
As long as slight excessive drawing-off is arranged, unacceptable permanent deformation will take place in ribbon, and this is also referred to as the defective drawing-off.If the drawing-off error is excessive, this just will directly cause ribbon to be broken, if set lowly excessively in this regional drawing-off, ribbon just has the danger of tending to form the sagging coil (sagging loop) that change is big more more uncontrollablely, if this situation ground further continues and can not get revising, in sagging coil, will form " tieing structure (knot formation) ".So tieing just keeps entering hangingly in the ribbon apparatus for placing, this also will cause tearing.
Defective drawing-off causes ribbon to be placed that uneven thickness is arranged, this follow-up phase at spinning process can not obtain full remuneration or can only be compensated by high cost, therefore, at carding machine be arranged in the quality that defective drawing-off meeting between the ribbon place apparatus on the carding machine degenerates the economic serviceability of spinning process and finally weakens the final products of cotton mill, i.e. quality of yarn of being produced.
With with form the same mode of sagging coil, the tearing of ribbon to be placed causes the interruption of producing, this also can cause sizable cost allowance.
For fear of described problem, according to DE 3734425, at output device with lead and be provided with not driven ribbon guide roller between the device, wherein, at least one ribbon guide roller is installed on the slack adjuster (dancer device) movablely and forms the ribbon circle that depends on ribbon tension force.In this case, each displaced position about slack adjuster detects and is used as the control variables that counter extensioin is accurately adjusted by electrical measurement.
The disadvantage of this scheme is that at first design cost height and measurement and control technology are very complicated, and another disadvantage is, because due to the effect of inertia, slack adjuster can only be followed the rapid variation of ribbon tension force in the mode of time delay.Similarly, the slack adjuster vibration that can be excited during the cyclic fluctuation of ribbon tension force.As a result, rely on disclosed device can't prevent tieing structure and defective drawing-off reliably.
Summary of the invention
Thereby, the purpose of this invention is to provide a kind of method, control device and weaving unit thereof that is used for placing the ribbon of exporting by spinning preparation machine, described weaving unit has been avoided above-mentioned shortcoming, and especially makes it possible to production uniform fibers bar, has increased production capacity simultaneously.
This purpose is to realize by a kind of method, control device and weaving unit thereof that is used for placing the ribbon of being exported by spinning preparation machine of the feature with independent claims.
In the method according to the invention, the drawing-off that provides is subjected to control automatically and changeably by means of previous defined canonical function in the process of placing ribbon, and this depends on the output speed of output device.
In addition, by means of previous defined canonical function, control device according to the present invention is arranged to depend on the output speed of output device and is controlled automatically and changeably drawing-off.
At this, the present invention is based on such empirical discovery: ribbon depends on the current each output speed of output device basically at the output device of spinning preparation machine and the best drawing-off of leading between the device of ribbon place apparatus.Yet the theoretical background of this phenomenon is not also made clear.
Described canonical function has defined in the output speed that is used as independent variable with as the relation between the drawing-off of dependent variable, wherein said output speed and thereby described drawing-off also change along with the time.Canonical function for example can be a multinomial, and canonical function also can be a segmentation definition.In order to find suitable canonical function, the stage before operation can be carried out suitable campaign.The automatic control of drawing-off will consider that output speed is from the actual conditions of being controlled automatically between resting period in ribbon.
The current setting value of output speed or the current actual value of output speed can be used to control drawing-off, the current setting value of output speed for example is predetermined by the mechanical control device of spinning preparation machine, and the current actual value of output speed is to detect with more suitable sensor.
As result of the present invention, can exempt the expensive system of the ribbon circle that is used for forming monitoring without doubt.Simultaneously can easily prevent to form node structure and defective drawing-off.
From various spinning preparation machines especially visible importance of the present invention the output speed that constantly increases for many years.The output speed of carding machine during ordinary production of often using is 400 meters/minute or higher at present.Yet, often be necessary the output speed that slows down significantly.Therefore, to provide so-called crawling exercises usually, can manually or automatically be adjusted when this crawling exercises has fault to take place subsequently in raw-material feeding process.The output speed of crawling exercises is such as only being 15 meters/minute.Thereby utmost importance is that the drawing-off with optimised adjustment is always turned round in big velocity interval.
Preferentially be provided with like this according to control device of the present invention, it is configured to control drawing-off by side by side controlling to lead into leading into the output speed of speed and output device of device.Can obtain counter extensioin in this way controls especially reliably.Yet, in this case, must guarantee that the output speed of output device can adapt to the working range of the carding machine that is positioned at farther upstream.
Thereby preferential being set to, described control device is configured to be used for assessing and the corresponding signal of the output speed of output device, and is configured to only lead into leading into speed of device by control by means of this assessment and controls drawing-off.At this, described whole device has just obtained a kind of simple structure.
The measuring-signal that comes from the sensor that detects output speed can advantageously be used as corresponding signal.This is used to control with regard to the actual value of having guaranteed output speed and leads into speed, thereby makes desirable drawing-off be set in high-precision mode.
Replacedly or can be additionally, have for example been pre-determined and represented the control signal of the current setting value of output speed to can be used as corresponding signal by an element of the mechanical control device of spinning preparation machine.This is always rational, if guaranteed that setting value is consistent substantially with actual value.
Detect output speed if be provided with sensor, output speed just can be regulated by means of the closed control circuit that improves drawing-off control so.

Advantageously providing canonical function, to be defined as it be monotonically increasing at main section at least, thereby drawing-off is that increase with output speed increases at this section at least.This is specially suitable, because test has shown that the risk that occurs defective drawing-off or ribbon broken string under high draft speed is lower.
Also advantageously, be continuous or quasi-continuous if canonical function is provided in main at least section, drawing-off is controlled continuously or quasi-continuously at this section at least so.By means of similar control device, can implement continuous control with pure form.If described control is carried out, just certainly existing step (steps), yet these steps are so little so that in fact they can ignore under digital technology.In this case, described control is quasi-continuous.
In addition, canonical function can be defined like this, at least one ribbon parameter is considered in the drawing-off control procedure, and described ribbon parameter for example is ribbon weight, ribbon cross section, fibre length, fibre orientation, the fiber share with hards or gib head, staple fibre share, moisture content and/or fibrous material itself.This is based on such discovery, and the ribbon that promptly has different qualities is also different to the reaction of same drawing-off.For example, when the fibre orientation of ribbon was higher, the generation probability of ribbon fracture and defectiveness drawing-off had just increased.This situation just needs low drawing-off.
Environmental factor also can influence drawing-off optimization.Therefore, at least one ambient parameter such as temperature and/or air humidity are taken into account during drawing-off when control, the function that sets up standard like this is suitable.
Same situation also is applicable to mechanical parameter.Therefore, canonical function is advantageously defined like this, and except output speed, other mechanical parameter of at least one of spinning preparation machine is arranged on the drawing-off control period such as the drawing-off of the inside stretching phase of spinning preparation machine and also is taken into account.
Advantageously, at least one value in described ribbon parameter, ambient parameter and/or other mechanical parameter is automatically detected, and is preferably detected continuously, so that the control drawing-off.This is to be suitable under the fast-changing particular condition in parameter.
Yet also possible is that at least one value in described ribbon parameter, described ambient parameter and/or described other mechanical parameter is controlled drawing-off by manual detection.For example can be achieved like this, operator's measurement environment parameter also transfers them to control device, transmits and for example can carry out by means of the control module of spinning preparation machine.

Fig. 2 is the schematic diagram according to another representative embodiment of weaving unit of the present invention;
Fig. 3 is the chart of canonical function;
Fig. 4 is the chart with canonical function of different parameters value.
The specific embodiment
Fig. 1 shows weaving unit 1, and it comprises spinning preparation machine 2 and the ribbon place apparatus 3 of exporting ribbon.Here carding machine (Karde) the 2nd is illustrated as the example of the spinning preparation machine 2 of output ribbon.Yet, the present invention also can be used on any weaving unit 1 of the spinning preparation machine 2 that comprises another output ribbon, and the spinning preparation machine 2 of described another output ribbon for example can be carding machine (Krempel), drawing machine (drawing frame) or combing machine.
By the shredding coarse fiber bundle, reduced the previous strong adhesive aggregation of individual fibers and produced cotton-wool as far as possible uniformly.Described cotton-wool is fed into fiber feed system 5.Described fiber feed system 5 comprises feed roller 6, and the task of feed roller 6 is the working ranges that cotton-wool are advanced to lentamente licker-in 7.Described licker-in 7 (also a plurality of licker-ins can be set) shredding cotton-wool once more forms flock and they is transferred to cylinder 8.Cylinder 8 transmits fibre bundle and crosses fixing carding element (not shown) and/or rotation cover device 9, and wherein fibre bundle is become independent fiber by shredding in the carding process of reality.
Through at cylinder 8 with fixedly after the combing between carding element and/or the rotation cover device 9, cylinder 8 is with the fiber loosely and take ribbon abreast to and doff in the system 10.The non-woven fibre FV that forms on ribbon doffs the doffer 11 of system 10 is by taking off cotton roller 12 from doffer 11 doffings, and then is transported to compression set 14 by a pair of delivery roller 13.The task of the compression set that only schematically shows here is that combing non-woven fibre FV forms ribbon FB.For this reason, described compression set comprises movably and/or the guider of fixed and arranged, for example comprises the cross(ed) belt device 14 of the funnel that is positioned at one or more cross(ed) belt downstream.
Described take off cotton roller 12 and this to the drawing-off between the delivery roller 13 normally by the mechanical couplings between the delivery roller 13 be determined in advance and in running, keep constant at described cotton roller 12 and this of taking off, described mechanical couplings is such as comprising gear and/or belt dressing.Yet described mechanical couplings can comprise a transfer point, for example has interchangeable disk or interchangeable transfer point of taking turns, thereby makes that the gearratio of described mechanical couplings and described drawing-off are adjustable.Yet the described cotton roller 12 that takes off also can be arranged to be driven to delivery roller 13 with this with being mutually independent.So the drawing-off between described roller 12,13 is with regard to the speed that depends on non-woven fibre FV and controlled.
The drawing-off that non-woven fibre FV is stood between delivery roller 13 and cross(ed) belt device 14 also can be adjusted by means of transfer point but be to keep constant in running, and described transfer point for example has interchangeable the wheel.Yet the drawing-off between delivery roller 13 and cross(ed) belt device 14 also can be controlled changeably by the matching design of driving of delivery roller 13 and cross(ed) belt device 14, for example depends on that the speed of non-woven fibre FV is controlled changeably.
Ribbon FB leaves cross(ed) belt device 14 and is directed to the output device 15 that is positioned at carding machine 2 exits then.Described output device 15 is such as being arranged to pair of discs roller 15.Via one or more ribbon guide rollers 16, ribbon FB arrives along traffic direction LR and leads into device 17, the described porch that is positioned at ribbon place apparatus 3 into device 17 of leading, and it is such as being configured to calender device 17.Yet the described device 17 that leads also can be arranged on device or assembly on the ribbon place apparatus 3.Such as, describedly lead that to be constructed to drawing frame into device 17 be feasible.It is known having the ribbon place apparatus that leads into device of being arranged to drawing frame, such as learning from DE 19721758.
Ribbon FB is placed in the ribbon container 19 by rotating disk 18.Described ribbon container 19 is such as being circular bar tube or rectangular strip tube.For ribbon FB can be placed in the mode of arranged loop or coiling, ribbon container 19 is installed in movably on the bar tube dish 20.When using circular bar tube, bar tube dish 20 moves usually rotationally, and bar tube dish 20 can be moved by translation under the situation of rectangular strip tube.
At output device 15 with lead between the device 17, ribbon FB has stood drawing-off V, and described drawing-off V is corresponding to the ratio into the output speed of speed and output device 15 of leading that leads into device 17.Crooked parantheses represents that ribbon has stood the zone of drawing-off V.Described zone begins to extend across ribbon guide roller 16 up to leading into device 17 from output device 15.Comprise drawing frame if lead into device 17, so should the zone just extend from output device 15 right up to the input roller of this drawing frame.
Output speed is to determine that by being equipped with the driving of giving on the output device 15 and being equipped with described drive ratio to electric machine controller FU1 in the described driving is as comprising output drive motors M1 and gear mechanism 22.Described output drive motors M1 is controllable motor via the feed frequency.In this case, output drive motors M1 is configured to threephase asynchronous machine M1 and electric machine controller FU1 is frequency converter FU1.Yet, also can use other type motor with corresponding motor controller.Described frequency converter FU1 is integrated in the mechanical control device 21 of carding machine 2 or is connected to wherein at least.
In the representative embodiment that illustrates, motor M 1 not only drives described output device 15 but also drive described cross(ed) belt device 14.Yet motor M 1 also can be arranged to other parts of only driving output device 15 or also driving carding machine 2, and for example delivery roller is to 13.The ratio of the output speed of the running speed of cross(ed) belt device 14 and output device 15 remains unchanged at the run duration of carding machine 2, but can adjust by means of the transfer point on gear mechanism 22 usually, such as by means of interchangeable belt pulley or gear and be adjusted.Similarly, also can be arranged to cross(ed) belt device 14 and output device 15 is so driven, making can have variable drawing-off between described cross(ed) belt device and described output device.Thereby described drawing-off can be according to the speed control of ribbon FB.For make carding machine 2 can fault-free the ground operation, the control of described output drive motors M1 is realized by signal S3 that this signal S3 comes from and driven delivery roller at least to 13 electric machine controller FU3 by described electric machine controller FU1.
For the sake of clarity, being positioned at the motor in electric machine controller FU3 downstream and delivery roller does not illustrate 13 driving.Yet, the synchronism that the fiber web of being arranged continuously or ribbon guider 13,14,15 are essential thereby guaranteed.
On the other hand, lead into leading of device 17 and be by electric machine controller FU2, lead into drive motors M2 and gear mechanism 24 and determined into speed.Described to lead into drive motors M2 can be threephase asynchronous machine M2 equally, and described electric machine controller FU2 can comprise frequency converter FU2.The part of the mechanical control device 23 that described electric machine controller FU2 is a fiber place apparatus 3 or be to be assigned to fiber place apparatus 3 at least.In the example that illustrates, rotating disk 18 and bar tube dish 20 are also driven by leading into drive motors M2.Yet, also independent motor can be set for this reason.In this representative embodiment, gear mechanism 24 has pre-determined constant velocity ratio for leading into device 17, rotating disk 18 and bar tube dish 20.This velocity ratio can only can be changed by the expensive displacement to interchangeable part.
Now provide control device 26 according to the present invention to be controlled at output device 15 and lead drawing-off V between the device 17.Described control device 26 has been assigned with a sensor 25, and described sensor 25 detects the output speed of output device 15 and this speed is transmitted as signal S2.Use previous definition canonical function VG and with the corresponding signal S2 of output speed, control device 26 has just been determined the value of predesignating for conceivable drawing-off.Replaceable signal S2 is, control signal S3 also can be transferred to control device 26 and determine this value of predesignating, because described signal S3 is also corresponding with output speed.
Because the output speed of output device 15 is known, is used to lead and is calculated and to be used as signal S4 into the value of predesignating of speed and be sent to the electric machine controller FU2 that leads into drive motors M2.Described electric machine controller FU2 has now adjusted and desirable led into speed and thereby adjusted the drawing-off V that obtains from canonical function VG.
The control module 28 of the spinning preparation machine 2 that also is illustrated can be used to operating control device 26.The memory device 29 that illustrates equally is assigned to mechanical control device 21, and this memory device 29 is connected to control device 26 by unshowned circuit, thereby makes canonical function VG can be stored in the memory device 29 and can be read by control device 26.
Fig. 2 shows another representative embodiment of the present invention.Here control device 26 is configured to not only to be used to control output speed but also is used for control lead into speed.For this reason, signal S3 is provided for control device 26, and this signal S3 has represented the speed of the working region of the carding machine 2 that is positioned at the upstream.Control device 26 utilizes this signal S3 to calculate signal S6, and this signal S6 is sent to the electric machine controller FU1 of output drive motors M1.The output speed that this signal S6 is used to pre-determine the rotating speed of output drive motors M1 and pre-determines output device 15 thus.
Actual output speed is detected continuously by sensor 25 and is fed back to control device 26 as signal S2.If actual output speed is different from predetermined output speed, so described signal S6 will controlled device 26 correction up between the two difference disappearance.Therefore, output speed is controlled via closed control circuit, and described closed control circuit comprises control device 26, electric machine controller FU1, output drive motors M1, gear mechanism 22, output device 15 and sensor 25.
Simultaneously, desirable drawing-off V determines by canonical function VG.For this reason, can use output speed or the preferred actual output speed of being calculated by control device 26 that is also promptly recorded.In order to set desirable drawing-off V, just must adjust now and lead leading into device 17 into speed.For this reason, control device 26 is sent to electric machine controller FU2 with signal S4, and described electric machine controller FU2 has pre-determined a corresponding rotating speeds for leading into drive motors M2, makes to lead into leading into speed of device 17 to be determined in advance via gear mechanism 24.
Described leading into speed measured continuously by means of sensor 27 and is fed back to control device 26 as signal S5, thereby also is provided with a closed control circuit at this.
By regulating output speed and leading, just can guarantee that definite drawing-off V can be kept higher precision by canonical function VG into speed.For example, since any deviation of the skid caused drawing-off V relevant of motor M 1, M2 with load can be compensated in this way.
Fig. 3 shows the chart of canonical function VG.Output speed LG is indicated on the abscissa and consequent drawing-off V is indicated on the ordinate.Because output speed LG depends on time t, so drawing-off V is also relevant with the time.Canonical function VG can be described as VG (t)=f (LG (t)) usually on mathematics, this is continuous and monotonically increasing in its whole domain of definition scope.The described domain of definition comprises crawling exercises speed KG and permanent speed AG, and extends to the right and left.Crawling exercises drawing-off VKG according to canonical function VG will be significantly less than normal operation drawing-off VAG.
Also indicated curve D G among the figure, this curve D G is illustrated in when being lower than drawing-off V, all may form the sagging coil of continuous increase at each output speed LG place.Also indicated curve FVG among the figure, it has represented to be expected the lower limit of defective drawing-off.At last, curve B G has provided the break limit that causes ribbon FB to be torn.Curve D G and curve FVG can determine by rule of thumb.Thereby canonical function VG just can be defined between described curve FVG and the DG.
Fig. 4 shows the canonical function VG that ribbon parameter F P, ambient parameter UP and/or other mechanical parameter MP are taken into account, thereby its general formulation is VG (t)=f (LG (t), FP (t), UP (t), MP (t)).
Canonical function VG is plotted as and not only is applicable to first value combination W1 but also be applicable to second value combination W2.The combination of described value W1, W2 comprise the ribbon parameter F P, the ambient parameter UP that are taken into account and/or the value of other mechanical parameter MP separately.Described value combination W1 is such as the ribbon parameter F P that comprises the ribbon FV with high relatively staple fibre part.Because the fiber that causes thus has lower bonding, than the value combination W2 situation of the ribbon parameter F P that is fit to comprise the ribbon FV with lower staple fibre part, predetermined here drawing-off V is lower.
The present invention is not limited to representative embodiment shown and that describe.Correction in the Patent right requirement scope is possible at any time.Therefore, also can provide control device 26 to be integrated in the ribbon place apparatus 3, such as in mechanical control device 23.Equally, it also is possible control device 26 being set to an independent device.
