Definitions
- the invention relates to a device for cleaning a Kämmgarituren existing Kämmsegment one, rotatably mounted on a shaft round comb of a combing machine, which combs out a, from a nip of a nipper aggregate tuft, with at least one, in the region of the outer circle of Kämmsegmentes of Rundkammes arranged cleaning element for cleaning the Kämmgarnitur the Kämmsegmentes during a Kamm mecanics.
- the combing machines customary today usually have eight combing heads arranged next to one another.
- the, in the form of Wattebahnen the respective nipper unit of each combing head supplied fiber mass is clamped by the nipper unit during the combing process.
- the end of the fiber mass projecting from the respective nipper unit (“pincer" for short) is usually called fiber tuft is called below the pliers via a shaft rotatably mounted in the machine frame, which is driven individually or centrally by a drive unit.
- the combed out components are deposited for the most part within the combing segment and transported downwards by the rotation of the circular comb, where they reach a region in which the bristles of a brush roll engage in the enveloping circle of the combing segment.
- the combing segment consists, for example, of a plurality of Kämmgarnituren arranged one behind the other, which have adjacent clothing strips.
- the rotational movement of the brush roller is opposite to the rotational movement of the circular comb, so that in the region in which the bristles of the brush roller engage in the Kämmgarnitur, the absolute direction of movement of the Kämmgarnitur and the bristles of the brush roller is rectified.
- the peripheral speed of the brush roller is greater than the peripheral speed of the circular comb, resulting in a shift (flow) of the bristles within the combing.
- the bristles of the brush roller are used to stripped yarns of Kämmsegmentes, combed out components and removed under the action of a suction to a suction.
- the suction channel connected to a vacuum source is connected to a housing in which the brush roller is rotatably mounted. This housing at least partially encloses the round comb mounted above the brush roller.
- the applied negative pressure acts into the area above the circular comb and supports the retraction of the tuft in the combing during the combing process.
- the invention is therefore based on the object of proposing a cleaning device, or a monitoring device for a cleaning device for a circular comb of a comber, with which the disadvantages of known designs are eliminated and a qualitatively consistent combing work is guaranteed.
- This object is achieved, on the one hand, by a method in which the mass of the combed components depositing in the combing set is continuously recorded or monitored in order to keep the combing set clean, the cleaning intensity of the at least one cleaning element being determined on the basis of the detected values be adjusted according to given basic values.
- the components deposited or fixed in or on the combing set of the combing segment directly after the combing out process are detected by a measuring system (sensor system) even before the combing segment reaches the effective area of the first cleaning element. That Based on the measured mass already the cleaning intensity of the cleaning element can be adjusted accordingly. If it is the cleaning element is provided with a bristle brush roller, z. B. at a measured against a predetermined basic value higher mass, the rotational speed of the brush roller can be increased by a certain amount, so that the cleaning action is sufficient to completely remove the components located in Kämmsegment from the Kämmgarst the Kämmsegmentes and supply a known suction. Such a process is essentially aligned with variations in the combed mass (percent combing).
- the proposed method also relates to an embodiment, wherein the detection of the mass of the components located in the combing - seen in the direction of rotation of the circular comb - takes place directly after a cleaning element. This can be monitored directly the cleaning effect of the cleaning element and then corrected. Ideally, there should be no material are more within the Kämmgarit when it has been acted upon by the cleaning device, or from the cleaning element. If, however, a residual mass of constituents (eg noils) within the combing assembly is found after passing through the cleaning element, this may be due to the following causes.
- the cleaning effect (or cleaning intensity) of the cleaning element itself may deteriorate due to wear on the cleaning element (eg shortening of the bristles in a brush roller) and, secondly, the cleaning effect may also decrease if, for example, a higher combed mass is to be processed or combed material adhesive bonds (eg over honeydew) or other soiling or whirlwinds.
- a device wherein seen at a radial distance to the enveloping circle of the combing segment and in the circumferential direction of the circular comb, at least one means for detecting the mass of, located within the combing segment, combed out components is mounted, wherein the means with a Control unit is connected, which is connected to a display device and / or with a control of the at least first cleaning element, via which the cleaning intensity of the first cleaning element is adjustable.
- deviations from predefined setpoint values can be determined immediately and transmitted simultaneously via a display by an operator. This can then initiate immediate measures, so that the combing of the combing segment is freed of unwanted deposits to restore a complete combing action.
- the display device can be made as a visual display on a monitor or via a signal lamp. It is also possible to transmit the detected disturbance (contamination) to the operator via an audible indication to trigger an immediate intervention.
- the control unit which continuously transmits the detected values of the mass of the combed components located within the combing segment, directly to the control of a cleaning system.
- Acting element acts to adjust the cleaning effect of the respective cleaning element according to the determined values. That is, in this case, the adjustment of the cleaning device is carried out automatically and without intervention of an operator.
- the previously described visual and acoustic display means may also be used. This is particularly advantageous if the degree of contamination detected by the monitoring means can not be eliminated by the automatic increase in the cleaning effect. In this case, then a manual intervention for elimination is necessary. This can occur if the wear of a cleaning element (for example the bristles of a brush roller) is so great that it is no longer possible to automatically increase the cleaning effect.
- the means for monitoring the contamination of the combing segment - seen in the direction of rotation of the circular comb - is arranged between the at least first cleaning element and the clamping point of the nipper unit.
- This makes it possible to monitor the cleaning effect (cleaning intensity) of the first cleaning element directly after the first cleaning stage and to trigger appropriate measures via the control unit so that any remains of combed components remaining between the sets are removed in the subsequent cleaning cycle with.
- a known brush roller as a cleaning agent z. B. whose speed can be increased via the control unit or the penetration depth of the bristles in the Kämmgarnitur. The latter is achieved by reducing the distance between the axis of the circular comb shaft and the axis of the brush roller.
- a pneumatic suction element is used to clean the combing segment, the negative pressure applied to the suction element can be increased in order to set an increased cleaning effect (cleaning intensity).
- the means - seen in the direction of rotation of the circular comb between the nip of the nipper unit and the at least first cleaning element is arranged. This makes it possible to adjust the cleaning effect of the subsequent first cleaning element to the present composition of the combed components. This can be greater mass fluctuation of combed components (percentage Kämmlingsanteil) compensated and the cleanliness of the Kämmgarnitur the Kämmsegmentes be ensured.
- values stored in the control unit are compared with the determined actual values and, according to the deviations, control commands are sent to the controller of the subsequent second cleaning stage in order to adjust the cleaning intensity accordingly.
- control commands are sent to the controller of the subsequent second cleaning stage in order to adjust the cleaning intensity accordingly.
- the first cleaning element is a mechanical cleaning element and the second cleaning element is a pneumatic cleaning element.
- the first mechanical cleaning stage By the first mechanical cleaning stage, the components between the Kämmgarnur be solved and for the most part removed and deposited.
- the subsequent second pneumatic cleaning stage removes the remaining remaining components, some of which have already been dissolved at the mechanical cleaning stage.
- the means comprises one or more optoelectronic sensors, which are arranged within a, extending transversely to the direction of rotation of the circular comb width of the Kämmsegmentes.
- the entire width of the hairline can be detected.
- At least one line camera aligned transversely to the direction of rotation of the circular comb is used as means for monitoring the combing set.
- the mechanical cleaning element consists of a, at a radial distance to the shaft of the circular comb rotatably mounted cleaning brush, which has cleaning elements whose outer circle intersects with the outer circle of the combing segment and the pneumatic cleaning element consists of a, connected to a vacuum source suction, the suction opening extends at a radial distance and over a partial region of the enveloping circle of the combing segment.
- suction opening of the pneumatic cleaning element - seen in the direction of rotation of the circular comb - is arranged between the interface of the enveloping circle of the combing segment with the enveloping circle of the cleaning elements of the cleaning brush and the nip of the nipper unit.

- a sensor means S1 is mounted on the housing 50 and at a radial distance e from the enveloping circle HK. About this sensor means S1 whether and how much still combed material (noils, nits and other contaminants) is still within the combing segment 7, and their Kämmgarnituren.
- the sensor means S1 (or S2, S3) can consist of a plurality of juxtaposed sensors F, which are mounted at a distance next to one another over the width b of the combing segment 7. This makes it possible Kämmsegment 7 over the entire width b to scan.
- the sensors F can be known optoelectronic sensors which convert the light 77 reflected by the combing set into an electrical signal. These signals from the individual sensors are then transmitted via the line 70 to the control unit ST and, in comparison with values stored in the control unit, provide a measure for the occupancy or soiling of the furrows after the cleaning stage with the brush roller 44 stored in the control unit ST values which are used to evaluate the signals of the sensors F, it is, for. For example, to calibration values, which were determined via the sensor means S1 of the Kämmgarnitur when there was no combed material in the Kämmgarnituren. On the one hand, the color values of the surfaces of the combings and, on the other hand, the position of the clothing strips S (FIG. 3) were recorded. Based on the different color values of the stored calibration values can be determined or calculated by the control unit ST, the degree of contamination.

- these control signals are only generated if the calculated values are outside a tolerance range stored in the control unit.
- control interventions are triggered via the control unit via a contamination (remaining components K within the combing set) detected by the sensor unit S1
- these can be transmitted via the path 37 to the controller SM, for example, via which the speed of the motor MB is increased, which drives the shaft 46 of the brush roller 44. This increases the cleaning effect of the brush roller, in which case more bristles 45 per unit time intervene in the combing set 6 at the immersion point ET than was the case before the control intervention.
- This control intervention via the control unit can be carried out step by step, wherein after each intervention, a check of the effect on the sensor unit S1.
- a further control signal is triggered via the control unit ST, which is transmitted via the path 56 to a control SZ, which serves to control a cylinder 81 which is connected to the pivot arms 80 is articulated.
- the two pivot arms 80 are now pivoted upwards, wherein the radial distance between the shaft 46 of the brush roller 44 and the circular comb shaft 5 is reduced. This increases the immersion depth of the bristles 45 in the region of the immersion point ET, whereby the cleaning intensity is increased by the brush roller 44.
- Such a measure may be required if the bristles 45 have shortened as a result of wear, so that a sole increase in the rotational speed of the brush roller no longer brings the required increase in the cleaning effect, or cleaning intensity with it.
- the effect of the adjustment of the immersion depth is continuously monitored via the sensor unit S1 and transmitted to the control unit ST.
- control unit If the introduced control measures are no longer sufficient to clean the combing set up to a maximum degree of contamination stored and predetermined in the control unit, this is communicated to the operator via suitable signaling devices (eg via a screen 75 shown schematically or also acoustically), or the machine is shut down.
- suitable signaling devices eg via a screen 75 shown schematically or also acoustically
- control unit corresponding control programs may be stored, based on which the control commands for influencing the cleaning intensity of the brush roller 44 are triggered.
- the attachment of an additional, second cleaning element 58 is proposed with a suction channel 60.
- the second cleaning element 58 is - seen in the direction of rotation D of the circular comb 4 - downstream of the brush roller 44 and located in the area between the immersion point ET of the brush roller 44 in the Hüll Vietnamese HK the Kämmgarnitur 6 and the clamping point KS of the pliers 1.
- the suction channel 60 of the cleaning element 58 opens into a suction pipe 61, which is in communication with a further negative pressure source P1.
- the extracted under the action of the vacuum source P1 components are transferred via a channel 63 in the channel 35, via which they are supplied under the action of the vacuum source P a central collection point, not shown.
- the opening 65 of the suction channel 60 which projects toward the circular comb 4, is attached at a distance from the enveloping circle HK of the Kämmgarnituren 6 of the circular comb 4.
- the opening 65 may extend arcuately in accordance with the contour of the enveloping circle HK.
- the rear side wall 68 of the suction channel 60 is at an acute angle to Opening 65 of the suction channel 60 is arranged. This results in a suction air flow SL in the direction of rotation D of the circular comb 4, which is aligned approximately tangentially to the base body GK of the circular comb. This suction air flow SL is aligned approximately vertically to the front tooth flanks, not shown, of the teeth of the combing set.
- the small distance between the suction opening 65 and the enveloping circle HK of the Kämmgarnuren ensures that the air flow generated by the suction channel 60 is substantially limited to the region of the suction opening 65 and no uncontrolled air currents are generated within the housing 50, which the Combing and soldering process could negatively influence.
- a triangular shielding element 22 is mounted within the housing 50, which extends parallel to the circular comb shaft 5 over the entire width of the housing.
- the arcuate surfaces of the shielding element 22, stand at a small distance from the enveloping circle HK of the Kämmgarnuren, or the enveloping circle HB of the bristles 45 of the brush roller 44 opposite. This ensures that no disturbing countercurrent to the suction air flow SL of the suction channel 60 is generated by the suction air flow SA generated in the housing 50.
- an additional, second cleaning element 58 is provided with a suction channel 60.
- the remaining elements of Figure 2 correspond to the elements as shown in Fig.1.
- the sensor unit S1 described in FIG. 1 is located between the second cleaning element 58 and the clamping point KS of the forceps 1 in the exemplary embodiment of FIG. That is, the measured values delivered to the control unit ST via the line 70 are likewise evaluated, as described for FIG. 1, by means of basic values (tolerance and basic values) present in the control unit and, if necessary, corresponding control signals for increasing the cleaning intensity at the first and / or at the second cleaning stage (44, 58) generated and transmitted.
- the cleaning intensity at the second cleaning stage can be increased by increasing the vacuum applied to the suction channel 60 via the negative pressure source P1.
- the controller SA of the vacuum source P1 is controlled via the path 66 by the control unit ST in order to adapt the negative pressure accordingly.
- control commands from the control unit ST which are triggered after detection of a contamination of the combing set 6 by the sensor unit S1, can be transmitted on the basis of a program stored in the control unit ST.
- the cleaning intensity of the brush roller 44 can be increased, as already described in the embodiment of Figure 1. Should this not be sufficient to reduce or eliminate the contamination of the Kämmgarnitur 6 (following the two cleaning stages 44, 58), so the controller SA is driven to increase the negative pressure of the vacuum source P1 to the suction of the suction 60 too increase.
- the sensor unit S2 indicated in dashed lines in FIG. 2 serves for presetting the cleaning intensity of subsequent cleaning stages, as has already been described in the exemplary embodiment of FIG. This makes it possible to adjust the intensity (cleaning effect) of the cleaning stages to fluctuations with respect to the percentage of noil content and to compensate for these.
- a dashed line sensor unit S3 may be provided instead of the sensor unit S1.
- the mass of the contaminants detected by the sensor unit S3 (residual constituents of the combed-out components K which have not been removed by the brush roller 44) is transmitted to the control unit ST via the line 72.
- control unit ST transmits control commands to the controller SA and the negative pressure of the vacuum source P1 is correspondingly adjusted or increased. If this adaptation does not result in a reduction in the detected contamination, the cleaning intensity of the first cleaning stage, the brush roller 44, can also be increased via further control commands from the control unit ST (as already described). This stepwise control of the individual cleaning stages (44, 58) can also be carried out via a predetermined program stored in the control unit ST. Of course, acoustic and / or visual warning functions for the operator are triggered in this case as well, provided that the adjustment of the cleaning steps does not bring about a remedy in the detected degree of contamination.
- the proposed device dispenses with the cleaning cycles of the combing machine, which have hitherto been carried out in certain time intervals, in which the comb of the combing machine moves slowly and at elevated speeds. ter speed of the brush roller is cleaned. The omission of this special cleaning cycle increases the productivity of the combing machine.
