Abstract
The invention relates to a control device for the controlled blow-out of a needle strip (9), especially of a top comb (6) of a combing machine, by means of a blowing-out device (8, 10, 11, 12, 13), via which compressed air is blown at time intervals between the free passages of the needle strip (9). The known devices for controlling the blowing-out device are based on the mechanical or electromechanical principle. These control devices on the one hand can be influenced by existing machine tolerances, with the result that an exact blowing instant or blowing interval cannot be defined, and on the other hand are restricted in their adjustability to different boundary conditions. It is therefore proposed to form the control device from a microprocessor (15) for controlling the blowing-out device.
Description
The present invention relates to a kind of device that utilizes a blowning installation that the air blowing of the top comb of card wire batten, particularly combing machine is controlled, compressed air is passed through in the clear passage of the inherent card wire batten of certain time interval by this device.
In traditional combing machine, top comb is provided in a side of in the open area of jaw device.In separation process, the separated roller in rear portion of separated cotton clump draws and the card wire of process top comb.What the roller that so just guaranteed not to be combed in combing process was caught must also can obtain combing in the clump rear portion.Kept the impurity that still exists in the cotton clump here in the top comb, for example cottonseed, cotton knot and other impurity.
The part of these impurity is fallen in the suction channel of combing roller bottom and is got rid of.The remainder of impurity may accumulate in machine running process on the card wire of combing machine top combing or between the card wire.This will cause the infringement to top comb efficient.
Therefore having proposed various machineries in practice strips element, and for example stripping plate or brush accumulate thing to remove these.But these mechanical devices are very expensive on the one hand and increase jaw weight, also are subjected to the restriction of its efficient on the other hand.
Therefore in JP-AS-35-14 16, propose pneumatic cleaning device, purified the card wire district of top comb with compressed air.Described JP-AS is provided with from the outside laterally to blow the air blowing nozzle toward card wire.But from DE-PS37,22,481 as can be known: the compressed air that purifies usefulness in embodiment is directly vertically to supply from card wire by compressed air channel between card wire or card wire batten.Can guarantee that like this compressed air arrives all spaces between the card wire, thereby the thing that accumulates that blows off is downwards disposed.Proposed to control compressed-air actuated pulse chronologically among the in the end described embodiment, the impurity that blows out is taken away by the follow-up operation circulation of combing roller.Here proposing air pulse should trigger by the motion of combing circulation or the nipper of augmenting in case of necessity or another mechanical part of coordinating to drive of combing machine.More than but action mat one pure mechanical device or machinery-electric device are realized.Another method is exactly to trigger the supply of air by a delay switch.
In fact the combing machine of today generally reaches 360 combing cycles of per minute, and a combing cycle occurred within 0.167 second in other words.Actual air blowing interval is along with the corresponding angular adjustment of combing roller is to occur in 1/4 time that is 0.04 second of one-period.From the above-mentioned time interval as seen: to the control of compressed air unit or realize that the accurate interval control of blowing has very high requirement.But this is in order to prevent too early or to spend evening and blow interval shortcoming necessary.This accurate adjusting, the interval beginning of particularly blowing only could realize because these devices are subject to the influence of various tolerances on the one hand, having certain inertia on the other hand with traditional machinery or dynamo-electric method under extremely limited situation.
Therefore the purpose of this invention is to provide a kind of device that can realize that the air blowing interval is accurately regulated or changed.
This purpose reaches by following approach: control device is formed in order to the microprocessor that triggers blowning installation by one.From for example as can be seen, carry out opening and closing in a moment that accurately limits in order to discharge compressed-air actuated corresponding valve.Here the inertia of valve can be taken into account in simple mode.In addition, adopt microprocessor also can in triggering, take into account the delay time of the exhaust gas region between air is from the valve to the card wire very simply.
Microprocessor control preferably can be undertaken by program according to artificial predetermined numerical value, so just can regulate corresponding general condition by predetermined combing periodicity, gassing time for example, blow interval and air blowing intensity.
Microprocessor can trigger by the signal of sensor motion of detected clamped plate motion or other driving elements of coordinating mutually with clamped plate motion in a combing cycle.Here also can take into account the time-delay that signal output in the microprocessor is occurred.
Preferably sensor is attached in the zone of combing roller axle, it scans the predetermined corner of combing roller axle.
As previously mentioned, the present invention also advises blowning installation is set a predetermined leading time relevant with the moment of blowing and that depend on the combing periodicity.
Leading time is adjustable, to adapt to various tolerances or combing periodicity.
Equally, the air pressure of blowning installation also can correspondingly be controlled by microprocessor.
Generally be everlasting in practice through after the operation of certain hour machine being switched to the low cruise of short time, for example 30 minutes, purify intensity to strengthen it.In other words in machine low-speed motion process, strengthen to some extent in order to the separating effect of the combing roller brush that combs out the combing roller.Because after the speed of combing roller reduces, the combing roller brush is still kept original speed when high-speed cruising.In addition, the suction effect at exhauster(-tor also remains unchanged.Therefore purifying intensity in low cruise will increase to some extent.In order to strengthen blowning installation to for the purpose of the clean-up effect of top comb, also suggestion adapts air pressure in low cruise and between purifying area.This means that air pressure should be able to change, air pressure is increased so that remove the thing that accumulates of those stubbornnesses that may exist from the top comb zone.
Also the interval duration of suggestion air blowing should be regulated or preliminary election according to the combing periodicity in addition.All influences relevant with machine or material just can be smart and take into account simply and advance according to the combing cycle like this.
Further the formation of air pressure in the blowning installation is monitored and it is transported to control device by a sensor and just can make system realize self-monitoring.This comprises that the actual value that is risen by the determined pressure of sensor can be by relatively proofreading and correct actual value and setting value in control device.This also can make inside tolerance or deviation in the system be compensated.
Other advantages can be specifically described according to following embodiment:
Fig. 1 represents the partial section of a combing device schematic side view;
Fig. 2 represents one in order to expression air blowing pulses of air pressure/time diagram;
Fig. 3 represents that one has the schematic side view of the combing roller that the interval sequential of blowing describes.
Fig. 1 represents that one has the jaw unit 1 of a nipper plate 2 and a nippers 3.Nippers 3 can turn round round a swivel point 4 on the nipper plate 2.The place ahead at the nipper 5 of nippers 3 is provided with a top comb 6, and it removably is contained on the nipper plate 2 by a plate 7.Top comb 6 can design according to the embodiment of DE-PS3937899, and it is provided with an air duct 8 and between card wire 9, in the drawings the compressed air channel of expression not.Be connected to compressed air channel 8 at a pressure line 10, can supply through a valve 11 from a compressed air source 12 by its compressed air.Valve 11 is operated by a switch 13, and this switch is triggered by a control line 14 by a microprocessor 15.Microprocessor 15 is connected with input block 17 by another passage 16 same demonstrations.In addition, also expressing a corresponding control programs 18 among the figure briefly is loaded in the microprocessor 15.
Below jaw unit 1, be provided with a combing roller 19 that rotates, a combing fanning strip 20 is arranged on its part circumference.On combing roller axle 21 one division dish 22 is housed, its instantaneous rotary angle position mat one static sensor 23 detects, and is transported to microprocessor 15 by a lead 24.
The jaw unit 1 that the work that is in operation seesaws is with the transmission phase coupling mechanically of combing roller 19.Therefore accurately coordinate mutually with the angle position of combing fanning strip 20 each position of jaw unit.
In the embodiment shown in fig. 1, jaw unit 1 is to be on its rearmost position.This moment, jaw was closed, and the cotton clump of expression 30 jaws from lap 32 stretch out, and this lap is fed to combing fanning strip 20 by input roller 31 and prepared combing.After the combing, jaw unit 1 moves to the direction of detaching roller 33, and jaw is opened between this moving period.The fiber web 34 through combing between detaching roller 33 is carried a predetermined length backward by the counter motion of detaching roller.Cotton clump 30 releases owing to grip through combing of stretching out from jaw unit 1 move up, and contact with the fiber web of carrying 34 backward.By this motion, cotton clump reaches between the card wire 9 of top comb 6 simultaneously.The direction of rotation of detaching roller 33 is reversed again now, and is dilatory forward fiber web 34.In this process, the clamp area that the front end of cotton clump 30 enters detaching roller 33, therefore the fiber of the cotton clump 30 that combs out in the lap 32 from jaw unit 1 is drawn out, and is bonded together with fiber web 34.By means of this separation process, the rear portion of the cotton clump 30 that the fanning strip 20 that particularly is not combed is caught can be pulled out by the card wire 9 of top comb 6.So just, guaranteed can be combed out at cotton clump rear portion such as cottonseed, cotton knot and other impurity.
Here the suction airstream S that a part of impurity that strips out is sucked in the passage 35 is drawn onto the bottom.In suction channel 35, be provided with the brush 36 of a rotation in the below of combing roller 19, this is used for clearing up combing fanning strip 20.
The part impurity that is not eliminated out and peels off is still stayed on the card wire 9 of top comb 6 or between the card wire.If will not remove, the follow-up combing process of top comb 6 will be impaired.Therefore top comb 6 is provided with compressed air channel or air duct 8 as described like that, blows to the bottom by its compressed air between card wire 9.The impurity that is caught in like this is blown, and top comb is purified and carries out follow-up combing process.
Compressed air by a compressed air source 12 supplies enters the air duct of top comb 6 by a valve 11 and a pipeline 10.
For the compressed air supply is not produced for the purpose of the passive influence combing and adhesion process, must be controlled at the moment and the interval supply of accurate regulation to compressed air.This control is that mat microprocessor 15 is realized, it triggers by 14 pairs of switches 13 of passage valve 11 is opened.As described in detail later like that, pulse of compressed air be after the cotton clump of drawing out 30 is by card wire 9 and combing fanning strip 20 draw in a back with new cotton clump 30 before the time interval in be fed on the card wire 9.But can imagine that pressure pulse also will keep a very short time after combing fanning strip 20 is drawn in cotton clump 30, so that new cotton clump 30 is pressed among the combing fanning strip 20.This will depend on various general conditions, fibrous material for example, staple length and weather conditions etc.
In order accurately to carry out the switch moment of valve 11, microprocessor 15 receives a signal by index dial 22 detected combing roller angle positions by lead 24 from sensor 23.But also can adopt other detection systems to determine the corresponding angle position of combing roller.
In order to monitor compressed-air actuated formation, in pipeline 10, be provided with a sensor 37, it is delivered to real signal value in the microprocessor 15 by lead 25, actual signal is compared with setting value, the deviation that is occurred can by the back with correction control compensated.
Fig. 3 represents the side view of combing roller 19 and combing fanning strip 20 briefly.Here the whole circumference of combing roller 19 is divided into 40 calibration.This calibration is consistent with the calibration on the index dial 22.Index dial 22 is fastened on and can rotates on the combing roller axle 21 and through static sensor 23.In order to determine the moment of a certain indexing position, can detect separately by 23 pairs of all scale marks of mat sensor, perhaps only detect a calibration, and other indexing positions can be definite by calculating according to the rotating speed of axle 21.In existing embodiment, the detection of calibration 24 is equivalent to the top position of jaw unit 1.When jaw was mobile backward, the calibration on the index dial 22 was detected or calculates.Compressed air is at time interval t
BIn blow out, to purifying between the card wire 9.In an illustrated embodiment, the moment T of air blowing process from the calibration 27
BBegin and when calibration 34, finish.
Consider the inertia of valve 11 and switch 13, comprise the time-delay of electronics, must trigger in advance at moment T by microprocessor 15 and could guarantee that compressed air is at moment T accurately
BArrive between the card wire 9.
As shown in Figure 2, at each combing cycle t

But can imagine also and can apply compressed air every a combing cycle or with different intervals.This can utilize microprocessor 15 to regulate in advance by an operation board 17 in simple mode.Moment T in addition blows
BBut mat operation board 17 accurately preestablishes or regulates so that trigger by microprocessor 15.The general conditions interval and such as material, weather, staple length or other variations of blowing are adapted.The interval position of blowing only illustrates a kind of possible variable among the described embodiment with the relation of the rotation of combing roller.Also can imagine according to practical application and change the interval position of blowing.
In the combing machine running, be everlasting and carry out low cruise behind a certain setting-up time (for example 30 minutes) and realize between a purifying area.For example combing machine is reduced to 1/9 of normal combing periodicity, and the speed of the brush 36 of transmission still keeps its speed of service separately, and suction airstream S remains unchanged still.From the chart of Fig. 2 as seen: at the moment of low cruise T
L, gassing time is increased to t
B1Clean-up effect when strengthening low speed, it may continue 10 seconds.This moment, the pressure of air pulse increased to P2 from P1 in the present embodiment.So just, the dirt that can cling stubbornness excludes from the zone of card wire 9.Time interval t in the low cruise process between each air blowing pulse
K1Also increased.When machine returned to quick operation again, the air blowing interval adapted with quick operation immediately.
By working out corresponding program 18, but mat display screen and input block 17 come the various general conditions of preliminary election blowing purification.
Utilize microprocessor to trigger blowning installation and can realize air blowing the uniqueness of top comb card wire 9, accurate and preliminary election.
