Definitions

  • the invention relates to a control device according to the preamble of patent claim 1.
  • a fixed comb is attached in the usual way in the area of the forceps opening of the forceps unit.
  • the needles of this fixed comb pull through the tear-off cylinders, in particular the rear part of the torn fiber beard. This ensures that the rear part of the pulled-off fiber beard, which is not gripped by the circular comb during the combing process, is combed out.
  • the fixed comb retains the impurities, such as shell parts, nits and other impurities still remaining in the stripped fiber beard.
  • JP-AS-35-14 16 proposed that clean the fixed comb by compressed air in the area of the needles.
  • the JP-AS described has blowing nozzles which blow from the outside and transversely to the fixed comb needles.
  • designs are also known, for example from DE-PS 37 22 481, the compressed air for cleaning being fed directly between the needles or pin strips in the longitudinal direction of the needles via a compressed air channel. This ensures that the compressed air reaches the entire space between the needles and thus frees it of deposits that are blown out downwards.
  • the compressed air pulses be timed in such a way that the blown-out impurities are carried along by the subsequent working cycle of the circular comb. It is proposed to trigger the air impulses as a function of the comb play or the movements of an optionally assigned pliers or another coordinated driven machine element of the combing machine. This is preferably carried out using a purely mechanical or an electromechanical device. As an alternative, it is proposed to trigger the air supply by means of a timer.
  • the invention is therefore based on the object of providing means which enable an exact setting or a variable execution of the blowing interval.
  • control device is formed from a microprocessor for controlling the blow-out device.
  • a microprocessor for controlling the blow-out device.
  • the corresponding valves for releasing the compressed air are opened or closed at a precisely defined point in time.
  • the inertia of the valve can also be taken into account in the simplest way.
  • Using a microprocessor it is also very easy to take into account the delay time of the air on the way from the valve to the outlet area between the needles in the control.
  • the microprocessor can be controlled by signals from sensors which detect the movement of the pliers during a comb play or from another driven machine element which coordinates with the pliers movement. Here too it is possible to determine the delay time must be taken into account by the microprocessor when the signal is emitted.
  • the senor which scans a predetermined angle of rotation of the round comb shaft, be mounted in the region of the round comb shaft.
  • the lead time can be adjusted to adapt to different tolerances or comb play numbers.
  • the air pressure of the blow-out device can be controlled accordingly via the microprocessor.
  • the further proposal to monitor the pressure build-up of the air in the blowing device via a sensor and to transmit it to the control device enables the system to monitor itself. This means that the actual value of the pressure build-up determined by the sensor can be corrected by an actual value / setpoint comparison in the control device. It can also be used to compensate for internal tolerances or deviations in the system.
  • FIG. 1 shows a pair of pliers 1 with lower pliers 2 and upper pliers 3.
  • the upper tongs 3 are pivotally mounted on the lower tongs 2 about a pivot point 4.
  • a Fixed comb 6 attached, which is releasably connected to the lower pliers 2 via a web 7.
  • the fixed comb 6 can be formed between the needles 9 in accordance with the exemplary embodiment according to DE-PS 39 37 899 with an air duct 8 and corresponding compressed air ducts, not shown here.
  • a compressed line 10 is connected to the compressed air duct 8, via which compressed air can be supplied from a compressed air source 12 via a valve 11.
  • the valve 11 is actuated by a switch 13 which is controlled by a microprocessor 15 via a control line 14.
  • the microprocessor 15 is connected to a display and input unit 17 via a further path 16. Furthermore, it is indicated schematically that a corresponding control program 18 is loaded on the microprocessor 15.
  • a round comb 19 is rotatably mounted below the pliers unit 1 and is provided with a comb segment 20 on part of its circumference.
  • an index disk 22 is attached, on which the current angle of rotation position can be tapped via a fixed sensor 23 and transmitted to the microprocessor 15 via a path 24.
  • the pliers unit 1 which performs a back and forth movement during operation, is mechanically coupled to the drive of the circular comb 19, so that the respective position of the pliers unit with respect to the angular position of the comb segment 20 are precisely coordinated.
  • the pliers unit 1 is in its rearmost position, in which it is closed and the fiber beard 30 protruding from the pliers and a cotton wool 32 fed via a feed cylinder 31 is presented to the comb segment 20 for combing out.
  • the pliers unit 1 moves in Direction of the tear-off cylinder 33, the pliers opening during this movement.
  • the fiber fleece 34 which is already combed out between the tear-off cylinders, is conveyed back by a certain amount by a reversing movement of the tear-off cylinders.
  • the fiber beard 30 protruding and combed out of the pliers unit 1 moves upwards due to the dissolution of the clamping effect and comes into contact with the fiber fleece 34 which is returned. During this movement of the fiber beard, it simultaneously passes between the needle 9 of the fixed comb 6. Now the direction of rotation of the tear-off cylinder 33 is reversed again and the fiber fleece 34 is pulled off to the front. During this pulling-off process, the front end of the fiber beard 30 comes into the clamping area of the tear-off cylinders 33, whereby the fibers of the fiber beard 30, which are not retained by the cotton 32 in the pliers unit 1, are pulled out of the cotton 32 and soldered to the fiber fleece 34 or soldered . get connected.
  • a suction channel 35 In this suction channel 35 there is a circumferential brush 36 below the circular comb 19 which is provided for cleaning the comb segment 20.
  • the components that are not released and stripped down remain in part on or between the needles 9 of the fixed comb 6 and, if not removed, would impair the subsequent combing process in the fixed comb 6.
  • the fixed comb 6 is therefore, as already described, provided with compressed air channels or with an air channel 8, via which compressed air is blown down between the needles 9. This will blow out the stuck impurities and clean the fixed comb for the subsequent combing process.
  • the compressed air which is emitted from a compressed air source 12, reaches the air channel 8 of the fixed comb 6 via a valve 11 and a line 10.
  • a microprocessor 15 which controls a switch 13 to open the valve 11 via a path 14.
  • the compressed air pulse is applied to the needles 9 in a time interval after the drawn-off fiber beard 30 has passed the needles 9 and before the comb segment 20 sticks into a newly adjusted fiber beard 30.
  • the pressure pulse is maintained for a short time after the comb segment 20 has pierced the fiber beard 30.
  • this depends on various framework conditions, such as fiber material, stack length, climate, etc.
  • the microprocessor 15 receives a signal via the line 24 from a sensor 23 which taps the angular position of the circular comb 19 via an index disk 22.
  • a sensor 23 which taps the angular position of the circular comb 19 via an index disk 22.
  • a sensor 37 is attached in the line 10, which transmits its actual value signals to the microprocessor 15 via the line 25.
  • a setpoint / actual value comparison can then take place in the microprocessor 15 and any deviations can be compensated for by the subsequent corrected control.
  • FIG. 3 schematically shows a side view of the circular comb 19 with the comb segment 20.
  • the entire circumference of the circular comb 19 is divided into a forties index. This division corresponds to the division on the index disk 22.
  • the index disk 22 is connected in a rotationally fixed manner to the round comb shaft 21 and runs past the fixed sensor 23. To determine the point in time of a particular index position, either all of the index markings can be tapped individually by sensor 23 or only one index can be tapped and another index position can be calculated via the rotational speed of shaft 21. In the present example, the tapping of the index 24 corresponds to the foremost position of the pliers unit 1.
  • the compressed air is blown out between the needles 9 during the time interval t B for cleaning .
  • the blow-out process in the example shown begins at time T B at index 27 and ends at index 34.
  • a compressed air pulse is carried out at a time interval of t B during the comb games at a time interval of t K.
  • the compressed air pulses only every other comb play or at other intervals.
  • This can be preset in a very simple manner by using a microprocessor 15 via a control panel 17.
  • the blowing time T B can be precisely specified or set via the control panel 17 of the control via the microprocessor 15.
  • adjustments to the blowing interval can be easily adapted to changeable framework conditions, such as material, climate, stack length and the like.
  • the position of the blowing interval in relation to one revolution of the circular comb is only one possible variant in the example shown. A shifting of the blowing interval is also conceivable depending on the application.
  • the combing machine During the operation of the combing machine, it is customary to carry out a cleaning interval in slow speed after a certain set time (e.g. 30 minutes).
  • a certain set time e.g. 30 minutes
  • the combing machine is brought down to about 1/9 of the normal number of combs, the speed of the separately driven brush 36 being kept at its operating speed and the power of the suction air S being maintained.
  • the blowing time in t B1 increases at the time T L of the slow gear.
  • the pressure of the air pulse is increased from P1 to P2 in the present example. This makes it possible to remove stubbornly adhering dirt from the area of the needles 9.
  • the time interval t K1 between the individual blowing pulses also increases. Once the machine is switched back to the overdrive, the blowing intervals are adjusted to the overdrive again.
  • microprocessor to control the blow-out device enables individual, exact and preselectable blow-out of the fixed comb needle 9.
