Description

The The invention relates to a device for adjusting a Textile material processing machine, which has at least one feed device an approximately constant mass of fiber material below Feeds processing elements over which a certain proportion of the supplied Fiber material is deposited and further means are provided, the processed fiber material a subsequent drafting to form a sliver of a given mass.

In of spinning the textile material processing machines, z. The combers, which the textile material (fiber container) for the subsequent spinning machines (Flyer, ring spinning machine, rotor spinning machine, etc.) prepare accordingly be adjusted so that the desired quality and mass of the intermediate product (sliver) can be achieved.

there It is necessary that the existing adjustable elements on the machine optimally adjusted to each other in order the material specific values of the material to be processed the desired Result.

In usually would like the spinner for economic reasons the cheapest raw material (eg from a cotton) to use it from the customer desired quality of the final product (yarn). In order to make this possible It is necessary that the settings on the, the final spinning machines preceding preparation machines (eg combing machines) so that a high efficiency in the processing can be achieved can. To optimally adjust a machine to the available raw material it requires a high level of expertise from the operator and experience. In addition, the setting of the corresponding Machine very time consuming, especially as this in several places the machine must be made. Usually done after adjustment a test run on the machine to check the result obtained. If necessary, the Settings are adjusted on the machine.

As already described, the spinner is the most cost-effective Buying raw material in the market. That is, depending on the market price of the raw materials it can happen that often different raw material materials (eg cotton qualities with different stack (fiber length), or short fiber content submitted to the textile machinery for processing become. As a result, each time the settings of the Machines optimized for the new raw material (fiber material) need to be adjusted.

This is very time consuming and includes hazards (material defects, Committee) in itself, if the adjustment is not made correctly becomes.

The The invention therefore has as its object to avoid these disadvantages and the setting of the machines based on the raw material to be processed easy and safe and optimal to perform.

In The practice has been around for years with regard to the Manual settings of the machines for different raw materials to be processed made.

The Key figures of the raw materials used change only insignificantly and also the core elements of textile processing machines remained essentially constant and are occasionally only optimized.

On this basis, the invention is now based on, to solve the Task is proposed that the machine is a control unit connected to an input unit for the operator is, wherein stored in the control unit a knowledge database is over which on the basis of a stored in the control unit program on the basis of the input unit entered material-specific values (eg the kind, kindness and the mass) of the material to be processed, as well as the percentage Proportion of the fiber mass to be separated and the desired material-specific values (eg the quality and mass) of the material to be formed Sliver adjusting means for at least partially automatic Adjustment of feeders and / or the processing elements and / or the funding and / or the drafting system actuated become.

In The proposed knowledge base contains values for the machine setting captured and saved. These values are linked to characteristic values of the raw material to be processed, the percentage of material to be deposited, as well as with characteristic values of on this machine to be produced end product in the form of a sliver. The links stored in the knowledge base are based on experience, or can also be determined by experiments.

At the Raw material are z. Eg the characteristic values (eg for cotton) in the form of origin (eg California, Peru Pima etc.) and the Fiber length, or the stack (eg 1 3/32 '', 1 5/8 '' etc.) and the short fiber content, as well as the submitted fiber mass (g / m) deposited.

Around to obtain a fiber bundle with substantially long fibers, it is necessary to use the short fibers in the processing process essential to excrete. These deposited fibers are used in the combing process also noils called.

Of the percentage (number of noils) The excretion depends on the yarn number and yarn quality, which to be achieved in the subsequent spinning process. That is, to one to produce fine yarn, in view of the required Stiction between the fibers requires long fibers as a fine yarn less Has fibers in cross-section as a coarse yarn.

The characteristic values of the end product (sliver) are z. B. the Band number (ktex) and the regularity (CV value).

at the manual input of the operator via the input unit of the present indicative values of the raw material to be processed and the sliver to be achieved in connection with the desired percentage separation amount (Kämmling) compares the control of the control unit using a special stored program the entered values with the values which are stored in the knowledge database.

Provided this is a match is detected, based on the stored links on the Control unit actuating signals to the corresponding actuators for Setting the machine components generated. The actuators, or the machine components to be set (feed devices, Processing elements, conveyors, drafting system components) are natural equipped with appropriate sensors or position encoders, which the current position, or setting on the respective Transfer machine component of the control unit. On the basis of this Signals of the sensors are then set the machine components via the Actuators. Of course The sensors described are also used to monitor the adjustment over the Used actuators. That after the adjustment process is reached Position, or the new setting transmitted from the sensors to the control unit and there carried out a target / actual comparison. If necessary, readjustment is required until the default setting is reached. It can be provided that the set values determined on the basis of the knowledge base first displayed on a screen and by the operator beeing confirmed have to, before the actuators over the control unit is actuated become. this makes possible a check by the operator before the settings carried out become. Optionally, the operator can intervene here and correct manually if that makes sense.

Provided not all machine components to be adjusted with by the control unit are equipped with controllable actuators whose, on the Knowledge base determined attitude z. B. on a screen displayed. The operator can then manually adjust this setting make and carry confirm the manual setting of the control unit.

Should the entered values via the input unit does not match exactly with the values stored in the knowledge base, so can over the deposited program will be provided to the operator proposals on the screen for confirmation be submitted over the values stored in the knowledge base, which are the ones entered Values next come. The operator can then confirm the proposal or reject. However, it should be provided that manual overrides of the proposed settings at any time by authorized persons can be made. This possibility can be secured by a necessary input of a keyword and is thus only selected Accessible to people. This group of people is then allowed the entire machine setting completely or partially manually override.

With the proposed device is the kind of an operator Recipe for machine setting provided.

These adjustment is particularly advantageous in a comber, which with at least equipped with a reciprocating driven nipper unit is, which has a driven feed cylinder over which the Fasergut a rotatably mounted below the nipper unit Round comb discontinuously presented for combing out and the combed The end of the fiber material is transferred to a subsequent Abreisszylinderpaar, at which directly or subsequently via a device, a fiber fleece is formed, between the, in a front position befindlichem Nipper unit and the nip of the tear-off an adjustable Distance is available and the nonwoven fabric via appropriate means a sliver is summarized, the drafting with other, on fed to adjacent processing stations formed slivers.

In particular, in a combing machine, a plurality of machine components must be adjusted to a desired end product at a high efficiency of the machine to he hold. Faulty settings on the comber lead to quality and material losses with sometimes significant economic impact, especially as a part of the fiber material is lost as a loss of productivity on this machine. An optimal adjustment of this machine is therefore all the more necessary.

It It is suggested that the feed cylinder with an electromotive Drive is connected, whose control based on the entered Setting values are set and stored in the control unit. Thus, the individual control is possible, whereby the size of the Meal and also the type of food (supply / return) based on the entered Values are set. The control of the electric motor drive is with others on the combing process coordinate elements involved (eg the circular comb). In the DE-OS 195 06 351 and EP-A1-0 360 064 such individual drives have been described.

Of further it is suggested that controllable via the control unit Adjusting means are provided via which the front position of the nipper unit against the fix mounted Abreisszylindern is changeable. This distance It is also called ecartement and is particularly applicable to the existing ones Stack, or fiber length adjust. The attitude of the Ecartement influences in particular the combing. That a large Distance (ecartement) gives a higher combing than a small distance.

to automatic adjustment of ecartement via the control unit proposed that the pivotally mounted nipper unit over at least a lever rotatably mounted on the nipper unit is driven, wherein the free end of the lever rotatably connected to a forceps shaft is which over a clutch is coupled to a drive which is an intermittent Rotary movement of the gun shaft generated and the clutch controllable Means for releasing and detecting and providing a further adjusting means is that can be coupled with the forceps shaft and is suitable Pliers shaft when opened Turn coupling in the circumferential direction with respect to the coupling.

With this facility makes it possible the pivoting movement of the forceps shaft and thus of the nipper unit shift, which also causes the front reversal point of the pivoting movement and thus changing the ecartement becomes.

Around To achieve the same effect, it is also conceivable that the Distance between the nip of the tear-off cylinder and the nip is changed by feed cylinder and feed roller. Such solution is z. As shown in WO2004 / 088012 and described. At this solution the swing range of the nipper unit does not have to be moved.

to Setting the combing height and for adjustment to be combed out Material is suggested that the circular comb on its order catch with a combing set is provided, whose length and / or location about controllable adjusting means changeable is.

Around to do this can also be provided that the angle of the Garnitähneähne or - Needles over controllable adjusting means changeable is.

Furthermore It is suggested that the tear-off cylinders have one or more electromotive Single drives are driven, whose control based on the entered material specific values and the stored values of the Knowledge base about the control unit takes place. The case determined in the control unit Control impulses for The motors of the tear-off cylinders can be stored in a buffer for the Operation be stored retrievable.

A Such device is z. As shown in EP-PS 0374 723. With this setting influence on the soldering process can be exercised, which in particular affects the quality of the fibrous web to be formed Has.

Provided the tear-off cylinders do not have an electromotive single drive, but their movement over a conventional one mechanical transmission, it is suggested that the transmission for the Abreisszylinder is associated with at least one actuator, with the control unit is connected and which is suitable for the drive movement and / or to change the drive course of the tear-off.

A Such device is z. B. from DE-A1-195 27 950 refer. In this case, an additional motor is used to make the appropriate settings or changes in a planetary gearbox make. This additional engine could act as a so-called actuating means serve that over the control unit is activated.

It It is further suggested that between the breakaway cylinders and the nipper unit a Fixkamm is arranged, on which at least an actuator, which is connected to the control unit, via which the position of the fixed comb (or Fixkammnadeln) in their working position is adjustable.

Of the Term "location of the fixed comb set "can the Puncture depth of the clothing in the tuft, the angle of attack of Set to the conveying direction or the position (distance) of the clothing to the pliers. For the adjustment the location of the Fixkammes could also the simultaneous adjustment of two or all three of these Criteria apply.

Thus, the Auskämmung can be influenced with respect to the material to be processed. Such adjusting device for the fixed comb is for example in the DE 196 19 953 described and shown. In this case, the adjustment of the Fixkammes based on a signal of a Nissensensors, which detects the nits of the coma machine fleece formed and transmits corresponding signals to a control unit.

Provided the soldering not directly at the breakaway cylinders, it is suggested that following the tear-off cylinder, a device for forming a nonwoven fabric is provided, wherein at least one, with the Control unit connected adjusting means is provided which with at least connected to an element of the device, via which the soldering process the device can be influenced.

A such solution is. z. B. in the not yet published PCT / CH2005 / 000407.

Around the drafting system on the fiber length (Stack), it is suggested that the bearings the drafting rollers connected to the control unit actuating means assigned which for setting the delay distance between the drafting rollers provided at least in the main drafting field are.

Especially for adjusting the drafting system with regard to the processed Mass of the submitted material is proposed that at least the drive of the output roller of the drafting system with an actuating means to adjust its speed and thus the default size in connection is and the actuating means is connected to the control unit.

advantageously, can, as further proposed, the drafting with a regulator be provided. Thus, the uniformity of the sliver formed to be influenced.

Around the table distortion on the combing machine on to adjust the submitted material, it is proposed that the Speed ratio between the discharge rollers of the processing stations and the input roller of the drafting system over an actuator, which communicates with the control unit, adjustable is.

Furthermore is proposed for adjustment to the submitted material, that the processing elements are assigned to suction devices, the suction device with control flaps for regulating the Are provided with air circulation, which via control elements by The control unit are controlled, are adjustable.

For monitoring the settings over the control unit is suggested that with the control unit connected sensors for monitoring at least one of the predetermined material-specific settings provided are.

Advantageous is, if in deviation of the signal of a sensor from a predetermined Setpoint via a predetermined tolerance limit based on the knowledge database predetermined adjusting means for modification the machine setting are actuated.

Around will allow a manual intervention further suggested that based on the knowledge base generated signals for controlling the actuating means by the operator overridden are.

In 1 is a schematic view of an inventive claimed device for adjusting a textile material processing machine shown. In the present example, it is a combing machine, of which a combing head 1 is shown schematically in side view, wherein the fiber sliver formed on the individual combing heads (not shown) a mounted on the comber drafting 3 is supplied. The transfer of the at the combing head 1 formed sliver to the drafting system 3 will in the following 7 described and shown in detail.

In the present example is only a single combing head 1 shown. As a rule, however, eight such combing heads are present on a combing machine. Further details on the basic structure of a comber z. For example, from the literature "The short staple spinning - Volume 3 of Textile Institute, ISBN 3-908.059-01-1." Here, for example, on page 22 in Figure 28 together with the description accompanying the arrangement of eight working side by side in parallel Furthermore, on page 28 of this reference, the assignment of a following drafting system to the parallel side-by-side combing heads is shown and described.

The in 1 shown combing head 1 has a nipper unit 2 on top of that with an upper tong plate 4 and lower pliers plate 5 is provided. The lower tong plate 5 is in a clamp frame 6 attached, which via the pivot arms 7 and 8th is hinged pivotally. The front swivel arm 7 is rotatable about a rotation axis 12 a round comb 13 stored. The round comb 13 has a Kämmgarnitur 14 on, which is provided for combing a tuft F with Garniturzähnen or needles. A further description of this set is still in connection with the following 4 respectively.

The on the pliers frame 6 rotatable on a rotation axis 9 hinged rear swivel arm 8th is rotatably on a tongs shaft at its other end 16 attached. This tongs wave 16 performs an intermittent rotary motion, which z. B. of a push rod transmission schematically illustrated 18 is generated by the drive means 19 with the tongs shaft 16 communicates. The gear 18 stands with a main gearbox 20 in connection, which is driven by a motor M. As indicated schematically, the drive means 19 a clutch 22 on, about which the drive connection between the transmission 18 and the tongs shaft 16 can be interrupted. The coupling 22 is doing by an actuator 23 operated, which via a line 25 is in communication with a control unit ST.

In addition, an actuator 27 provided that via a clutch 28 with the wave 16 can be coupled to this with the clutch open 22 by means of the actuating element 27 in its angular position relative to the drive means 19 to adjust. The actuator 27 is over a line 29 connected to the control unit ST. The main motor M is via a line 31 controlled by the control unit ST. By the described adjustment of the forceps shaft 16 over the actuator 27 can the front end position of the pivoting movement of the nipper unit 2 be set, which is defined by the distance E. This distance E between the Klemmli never K a Abreisszylinderpaares 33 and the front end of the lower tong plate 5 is also commonly referred to as "ecartement." As already described, this ecartement is adjusted to the fiber length (pile) present and to a desired combing above the reciprocating nipper assembly 2 are winding rollers 34 . 35 rotatably mounted in the machine frame, which via schematically shown drive means 37 with the gearbox 20 are connected. If the comber, such. B. in the EP 0 455 171 A1 shown, is provided with an automatic Wattenansetzer, the drive of the winding rollers can also be done via a controlled single drive, via which the rotational movements of the winding rollers can be performed controlled during the piecing process.

On the winding rollers 34 . 35 is to be processed Wadding W on. The wadding web WT (called "cotton wool" for short), which has been unrolled from the lap roll W during the processing operation, becomes a feed cylinder 39 transferred, which rotatable in the clamp frame 6 above the lower forceps blade 5 is stored. The discontinuous rotation of the food cylinder 39 can be done via a not shown jack drive, the pivotal movement of the arm 11 the pivotally mounted upper tong plate 4 is controlled. This swivel arm 11 is about an axis 15 in the clamp frame 6 pivoted. The pivoting movement of the swivel arm 11 on the one hand by the reciprocating pliers frame 6 in conjunction with a spring not shown in detail Lement, on the one hand rotatable on the pivot arm 11 and on the other hand rotatable on an eccentric above the nipper unit 2 is stored. Further details about this arrangement can z. B. from the cited reference "The short staple spinning" on pages 22 to 24 are removed.

However, it is also conceivable the drive of the feed cylinder 39 via a schematically represented single drive 41 which is done via the control line 42 connected to the control unit ST. The drive connection between the drive 41 and the feed cylinder 39 is schematically through the drive path 44 indicated. Such a single motor drive for the feed cylinder is z. B. from the EP 0 360 064 A1 and the DE 195 06 351 A1 refer to.

In the area between the front end of the pliers unit 2 and the Abreisszylinderpaar 33 a FK fixed comb is arranged, which punctures during the tearing off with the Fixkammnadeln N in the tuft F In the example shown, the fixed comb FK is a schematically shown actuator 46 assigned, via a control line 47 communicates with the control unit ST. About this controllable by the control unit ST actuator 46 On the one hand, the delivery of the fixed comb FK within a comb play done and on the other hand, the puncture depth and / or the angle of the needles during the combing process can be adjusted. The term "needle N" may also be understood to mean the use of punched clothing teeth Such an adjustment device for the position of the fixing comb FK is known, for example, from US Pat DE 196 19 953 A1 refer to.

As also shown schematically, the Abreisszylinderpaar 33 via a motorized single drive 50 take place, which over the line 51 is controlled by the control unit ST. The drive connection between the drive 50 and the tear-off cylinders 33 takes place via the path 52 , Also the tear-off cylinders 33 following roller pair 32 can, as indicated by dashed lines, also from the drive 50 are driven. An example of such a single drive the Abreisszylinder is z. B. from the EP 0 374 723 refer to.

Like also in 1 indicated schematically is the circular ridge 13 a suction shaft 54 assigned, which via a channel 55 and a vacuum source 56 with a collection point 58 communicates. Within the channel 55 is a control flap 57 attached, which via an actuating element 60 is adjustable. The actuator 60 is over the line 61 connected to the control unit ST. Through the flap 57 the size of the suction air flow can be adjusted. On the representation of a brush roller, which in parallel distance to the axis 12 of the circular ridge 13 is arranged and for cleaning the Kammgarnitur 14 serves, was omitted for clarity. About the suction shaft 54 and the subsequent channel 55 become the of the circular comb 13 combed components removed and sent to a collection point 58 issued.

Furthermore, an actuator 62 shown that over the line 63 connected to the control unit ST. This actuator 62 is over the path 64 with the Kämmgarnitur 14 connected and used to adjust the Kämmgarnitur. It is conceivable that on the one hand the length L of the Kämmgarnitur 14 is adjustable and on the other hand, the adjustment of the angle of the teeth sets can be made. A more detailed description will be given in the following 4 described and shown.

Furthermore, a drafting system 3 shown that from an input roller pair 66 , a pair of center rollers 67 and a pair of outfeed rollers 68 consists. The roller pairs 66 and 67 are at a fixed distance from each other in a frame part 70 rotatably mounted. The roller pair 68 is in a frame part 71 rotatably mounted, which is opposite the frame part 70 is slidably mounted. By the displacement of the frame part 71 can the delay distance A of the main drafting zone between the pairs of rollers 67 and 68 be set. This setting can be made via a positioning cylinder 72 done by a jetty 73 with the frame part 71 connected is. The control of the actuating cylinder via a schematically illustrated valve 74 that with a pressure source 75 communicates. At the same time the valve becomes 74 via an actuating means 77 set, which over the line 78 connected to the control unit ST. The drive of the roller pairs 66 and 67 via a motor M1 via the line 80 is controlled by the control unit ST. The drive of the output roller pair 68 via the engine M2 via the line 81 is controlled by the control unit ST. Dashed is an actuating means 38 in the pipe 81 indicated, which indicates the activation of the motor M2 symbolically. Of course, this actuator is integrated in the control unit.

Following the drafting system 3 a sensor S is attached, which indicates the quality of a fleece funnel 82 monitored sliver FB monitored. The measuring signals of this sensor S are transmitted via the line 84 the control unit ST transmitted.

On the basis of these transmitted measurement signals and based on a target / actual comparison in the control unit ST, a control signal can be generated, which can be used to regulate the speed of the motor M2, the speed ratio between the roller pairs 66 . 67 and the roller pair 68 to change. Thereby, the drifting of the number (g / m) of the formed sliver can be prevented. If a sensor before the inlet of the drafting system 3 is provided for scanning the supplied fiber mass, it is possible to provide a regulating device to regulate thin or thick points in the fiber mass. Such a regulator is z. B. from the EP 0 376 002 refer to.

The control unit ST has a schematically shown knowledge database WD in which setting values for the machine setting are stored, these values being associated with characteristic values (type, quality, mass, short fiber content) of the fiber material presented to the combing machine and characteristic values of the desired end product (combing machine belt) are. Schematically, these relationships are repeated in the following 1a shown in more detail. For inputting the corresponding data of the material template as well as for inputting the data of the desired end product, an input unit TA (keyboard) is provided in connection with a monitor MT (screen), which are in communication with the control unit ST.

In 1a the relationship between the values of the material template to be entered by the operator and the desired quality of the end product in connection with the automatically controlled setting devices is explained in more detail. In this case, the material-specific values, which are indicated by the operator via the keyboard TA with the aid of a monitor MT, are listed in a diagram frame labeled "ON." These values, such as, for example, material type, stack, Quality and the mass of the fiber material presented are transmitted via the keyboard TA to the control unit ST.

Likewise, the operator transmits material-specific quality properties of the desired end product to the control unit ST via the keyboard TA, which is transmitted in the diagram frame labeled "OFF." At these values, the desired fiber mass, the uniformity (CV value) It would also be conceivable to enter a value indicating a maximum Nissenanteil.In this case, it is necessary to provide a Nissensensor, such as in the DE 196 19 953 A1 will be shown. As an example of the transmission of measured sensor values to the control unit ST, the sensor S was shown as an example, which is connected via the line 84 connected to the control unit ST. The sensor S can, for. B. monitor the uniformity, or the numbering of the formed sliver FB and deliver appropriate signals to the control unit ST. Based on a target / actual comparison within the control unit ST, predetermined actuators can be automatically controlled by the control unit if deviations are detected. When drifting the number of sliver FB z. B. the drive motor M2 driven, or be changed in its speed to the default size in the drafting system 3 adjust accordingly.

The control unit ST is associated with a knowledge database WD, in which empirical values are stored representing machine settings which are made via corresponding actuators 23 . 27 . 41 . 46 . 50 . 60 . 62 or 77 can be made. These empirical values are based on material-specific values (EIN) of the fiber material presented and to be processed and on material-specific values (AUS) of the end product to be obtained (eg a fiber sliver FB).

These Setting values stored in the knowledge database for the corresponding Actuators can in special trials or on the basis of practical experience be determined. When generating these control values with the Control unit using a special program becomes simultaneously carried out a plausibility check to To avoid incorrect settings. It would also be feasible for the operator execution the automatic adjustment of the machine components the intended To display settings on the screen MT to the operator the possibility to give them a check and with agreement to confirm.

It is also conceivable, only a part of the machine components to be adjusted via controlled adjusting elements to do while the rest Part still performed manually. It would make sense to automatically adjust those machine elements via the control unit ST, in which the manual setting is very time-consuming and expensive is.

ever by position (or quality) the operator in the spinning business can manually override provided by the control unit ST set values be.

Once the adjustment of the machine elements of the comber has been made on the basis of the already described material specific values (ON, OFF) using a special program in the control unit and the stored data of the knowledge database, a trial run of the machine can be performed. About corresponding existing ne sensors or visu The result of the machine setting can be checked or evaluated. If deviations are detected, the settings can be readjusted automatically via the control unit ST using the signals (values) supplied by the sensors. However, it is also conceivable to provide a manual regulation intervention in partial areas.

With the proposed system, it is possible on all sides, the machine setting when changing assortments fully or partially automatically in a relatively short time Time to do and on the other hand can be at a fully automatic Adjust this also by less qualified operating personnel carried out become.

In 2 A more detailed schematic of an automatic "ecartement adjustment" is shown and described which is incorporated herein by reference 1 has already been indicated. 2 shows a partial top view 1 in the area of the forceps shaft 16 , which rotatably with the swivel arms 8th is connected, which has a rotation axis 9 rotatable on the clamp frame 6 over the axis of rotation 9 are articulated. For clarity, was from the nipper unit 2 only the lower tong plate 5 shown which on the clamp frame 6 is attached. The lower tong plate 5 is in the position shown in a front end position and has in this position a distance E (Ecartement) to a nip K (see 1 ) of the Abreisszylinderpaares 33 on. The tear-off cylinder pair 33 is as shown schematically rotatably mounted in a machine frame MR.

The wave 16 is also stored on schematically indicated bearings LS fixed in the machine frame MR. The drive of the tongs shaft 16 done by a push rod gear 18 via the drive means 19 , which is designed here as a "push rod" 1 described is the push rod transmission 18 with the main gearbox 20 drivingly connected, which is driven by a motor M. The push rod 19 is at a hub 21 attached, which rotatably on a sleeve 17 is attached. This sleeve is by means of a coupling 22 rotatably with the forceps shaft 16 connected. At the clutch 22 can it be z. B. act to an oil-hydraulic clutch, which, as shown schematically, a clamping action between the shaft 16 and the sleeve 17 generated. The coupling 22 is over a line 24 supplied by a schematically indicated pressure source with an oil pressure, its supply or discharge by means of a valve 26 is controlled. The adjustment of the valve 26 done by an actuator 23 (eg a solenoid valve) which via the line 25 connected to the control unit ST.

On the wave 16 is rotatably a clutch 28 fixed, which faces a gear Z1 at an axial distance, which via a bearing 36 rotatable on the shaft 16 is stored. With the gear Z1 is a gear Z2 in drive connection, which via a shaft 30 with an actuating element, for. B. a servomotor 27 connected is.

The servomotor is over the line 29 controlled by the control unit ST.

The coupling 28 is with schematically indicated coupling elements 28a provided over which the clutch 28 and thus the wave 16 can be drivingly connected to the gear Z1. The actuation of the clutch 28 via the line 86 in a valve 85 empties. The valve 85 is, as indicated schematically, acted upon by a compressed air source and by an actuating element 87 (eg an electromagnet) controlled. The actuator 87 is over the line 88 connected to the control unit ST.

On the wave 16 is in the range of the sleeve 17 rotates an index disc 90 attached, which is provided with corresponding markings (not shown) from a sensor attached to the machine frame 91 be scanned. The sensor 91 gives his signals over the line 92 to the control unit. By scanning the markings of the shaft 16 rotating index disc 90 over the sensor 91 At any time, the instantaneous angle of rotation of the shaft can be determined.

If after entering the material-specific data (ON, OFF) see 1a via the control unit ST on the basis of the existing program another Ecartement E must be set, is triggered by the control unit ST an automatic or semi-automatic adjustment of Ecartement. This takes place when the nipper unit 2 , or the pliers plate 5 located in its forward dead center position. In this position is via the line 88 the actuator 87 controlled by the control unit ST and the valve 85 adjusted accordingly, so that the clutch 28 over the line 86 is supplied with compressed air. As a result, the gear Z1 via the schematically indicated coupling elements 28a with the clutch 28 and thus with the wave 16 coupled. Subsequently, over the line 25 the actuator 23 controlled, which is the valve 26 adjusted, causing the clutch 22 applied oil pressure via the line 24 and the valve 26 can drain. The connection between the shaft 16 and the sleeve 17 is thus solved.

Subsequently, the servomotor 27 over the line 29 controlled by the control unit ST. The servomotor 27 rotates according to the transmitted from the control unit ST control signals the shaft 30 and thus the gear Z2. Since this gear Z2 is in engagement with the gear Z1, this is also set in a rotational movement. As a result, also coupled to the gear Z1 clutch 28 and thus also the wave 16 twisted. By the rotation of the shaft 16 also the position of the swivel arms 8th changed, which in turn brings about a change in Ecartement E.

The adjustment of the shaft 16 is made by scanning the markings of the indexing disc by the sensor fixedly attached to the machine frame 91 supervised. In this case, a certain number of scanned marks on the index disc correspond by means of the sensor 91 a certain variable in the area of Ecartement E.

These Assignment is stored in the control unit ST. This can be the triggered by the control unit Adjustment precisely monitored and be carried out precisely.

As soon as the intended setting of the Ecartement E is completed, is via the actuator 23 the valve 26 operated and over the line 24 the coupling 22 put back under an oil pressure. The connection between the shaft 16 and the sleeve 17 and thus also with the slider crank gear 18 is closed again, or manufactured. Subsequently, the actuator is 87 controlled by the control unit and the valve 87 actuated. This will be the compressed air through the line 86 discharged and the coupling elements 28a solved. The connection between the coupling 28 and the gear Z1 is released again. If the other adjustable machine elements have already been set by the control unit ST or manually, the combing machine can be started for processing. The setting procedure of the items to be set is of course to be performed in a coordinated order. This sequence is stored as a function of the necessary settings in the control unit ST. Such a device for automatically setting the Ecartement is also considered independent of the claimed, controlled by the control unit setting on its own as an invention.

3 and 3a schematically show an adjustment of the length L of a set 14 a round comb 13 , In the processing of appropriate material templates, it may be necessary an extended combing 14 to achieve a desired combing. For a change of the combing 14 Under certain circumstances, it is also necessary to adjust the rotational speed or the rotational speed curve of the circular comb so that there are no collisions (eg recontinuation of the tuft already torn off) in the combing cycle.

The adjustment of the comb segment takes place in the present example via a circular ridge 13 attached servomotor 62 which over the line 63 communicates with the control unit ST. The servomotor 62 is over a pole 94 with a front set of clothing 14a connected, which opposite to a fix on the round comb attached rear clothing set 14b is guided adjustable. There are, of course, appropriate guides and means to provide, so that during combing no fibers and other deposited components between the rows of clothing 14a and 14b in the range of their coverage.

In 4 is another adjustment of the set 14 at the round ridge 13 shown. In this case, the angular position of Garniturzähne with respect to the Kämmrichtung KR via an actuating element, for. B. a servomotor 62a which carries its control signals via the line 63a from the control unit ST. The servomotor 62a is with a lever 98 with an actuator 99 connected. The actuator 99 , which in a schematically indicated link guide 100 on the circular ridge 13 is guided, has joints at certain intervals 95 on, on which actuator arms 97 are pivotally mounted. The other end of the respective actuator arm 97 is non-rotatable with a shaft 83 connected on which rotatable and in rows 93 in the distance juxtaposed fitting teeth 96 are attached. The waves 83 are laterally next to the respective clothing series 93 in bearing receptacles (not shown) rotatable on the circular comb 13 stored. The adjustment of the angle of attack of the clothing teeth 96 done by the displacement of the actuator 99 via the servomotor 62a and the lever 98 that with the actuator 99 connected is. By the displacement of the actuator 99 within the leadership 100 There is also a displacement of the joints 95 , Between the leadership 100 and the joints 95 the actuator is to provide sufficient clearance to allow it when moving the actuator arms 97 to no jamming comes. About the connection of the actuating arms 97 is due to the displacement of the actuator, a rotation of the respective waves 83 generated around their lateral bearings (not shown), whereby also attached to the shafts Garnitraschähne 96 be pivoted with respect to the Kämmrichtung KR. Thus it is possible the combing effect of the combing 14 automatically set according to the material template via the control unit ST. For the adjustment of the angular position of the clothing teeth 96 and thus their pressure angle in the presented tuft partially only a small displacement of the control element is sufficient 99 , The apparatus shown and described for adjusting the Engagement angle of the Garnitähneähne, as well as the device for adjusting the length of the toothed set are also considered independent of the controlled via the control unit setting by itself as inventions.

This soldering device has a sieve drum 110. on, which is rotatably mounted in the machine frame and is rotated continuously by a drive not shown in detail. Coaxial to the sieve drum 110. is inside the drum a rotatably mounted cylinder 111 attached, which on its circumference at least one opening 112 having. The cylinder 111 can, as shown schematically by an arrow, rotate in the opposite direction to the screen drum. The drive of the cylinder 111 takes place in the present example by a schematically shown single drive (motor) 115 who is over the line 116 communicates with the control unit ST. Inside the cylinder are fixed covers 113 arranged, which allows air circulation through the sieve drum into the interior of the cylinder 111 in these areas. An air flow (with a suction effect on the circumference of the sieve drum 110. ) is supplied by a vacuum source 118 generated, which with the interior of the cylinder 111 communicates and over the line 119 connected to the control unit ST. The described air circulation takes place through the openings shown 112 of the cylinder 111 and is determined by the respective rotational position of the cylinder 111 Approved. That is, as soon as the withdrawn fiber package through the tear-off cylinder 33 to the end of already on the screen drum 110. located fleece attached (soldering) to be located is one of the openings 112 in this area to create a suction effect there. By the rotation of the cylinder 111 This attachment process can be controlled accordingly. This is done by the appropriate control of the motor 115 via the control unit. Of course, z. B. the soldering distance by the corresponding control of not ge showed drive motor of the drum 110. via the control unit ST. To control the suction air flow is at least above the sieve drum 110. a shuttering AD provided.

With the device described above, the soldering process can be adjusted automatically based on the material-specific specifications via the control unit based on the knowledge database. In the example shown, the drive of the Abreisszylinderpaares via a single drive 50 from the control unit ST via the line 51 can be controlled. This control, or the rotational movement of the Abreisszylinderpaares can also be adjusted to the material-specific specifications, or set.

B. a fleece funnel 120 provided in which the fleece FV is combined to form a sliver C, which leads to a subsequent drafting system 3 is transferred. Further details of such a web-forming device are for. B. from the not yet published application PCT / CH2005 / 000409 with the filing date of 15.07.2005.

In the example of 7 a combing machine KM is shown in a plan view, wherein eight combing heads 1 work side by side in parallel. The at the respective combing heads 1 formed slivers B are discharged from discharge rollers C on a table T and deflected to guide roller U and to a subsequent drafting system 3 transferred. The delivery rollers C are on a drive shaft 101 attached, which is connected to a transmission G. The drive of the transmission G is carried out by a motor M3, via the connection 89 is drivingly connected to the transmission G.

Following the drafting system 3 is schematically shown a tape tray BA, in which a hopper wheel, not shown, that at the drafting system 3 formed sliver FB is placed in a pot KA. So that the tape transport between the delivery rollers C and the drafting system 3 , or the input roller pair 66 can be performed easily and without tape damage, the tape must be subjected to a slight tensioning distortion. This tensioning distortion is dependent in particular on the stack of the fiber material to be processed and is determined by the speed ratio between the delivery rollers C and the input roller pair 66 of the drafting system 3 certainly. If a certain tension distortion is to be set by a corresponding material template on the basis of the empirical values stored in the knowledge database, this must be adjusted accordingly by the control unit ST by changing the rotational speeds of the motor M3 or the rotational speeds of the motors M1 and M2. If this setting takes place at the drafting system drive, it is necessary to change the basic speed of the drafting system, whereby the speed ratio determining the delay is not changed. That is, the speeds of both drive motors M1 and M2 must be raised or lowered simultaneously.
