Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combing machine, and more particularly to a combing machine for combing out a fiber tuft supplied by a nipper unit, and a fiber tuft pulled out and extended. A piecing device that is provided at a predetermined interval in the detaching device for joining the detaching device, and the detaching device includes a pair of detaching rollers that are rotatably driven in the detaching direction. , Wherein the piecing device comprises a piecing roller which can be loaded by a pressing roller and which is rotatably driven in the detaching direction.

[0002]

2. Description of the Related Art In a known combing machine, a fiber tuft supplied by a reciprocating nipper is combed by a round comb arranged below the nipper, and then combed through the nipper. The bundles of fibers are supplied to the pair of detaching cylinders, and the pair of detaching cylinders separates the tufts fed out by a predetermined supply amount from the wrapping web. In this case, the drawn-out fiber package is stretched or drafted due to the different speed ratio between the nipper and the detaching cylinder. Starting from a feed rate of about 5 mm, in the detaching step, this feed rate is drafted by a factor of 6 to 3
It is stretched to 0 mm. In order to calculate the total length of the fiber package obtained after the detaching step, the length of the longest fiber finally drawn must be added to this 30 mm. When processing medium staples having a fiber length of about 30 mm, the overall length of the resulting fiber package is about 60 mm. The separated fiber packages are overlapped in a predetermined overlap by a rear end of the fiber fleece projecting from the detaching cylinder in a detaching step. In this overlapping step, the fiber fleece is transported forward in the direction of the second guide roller pair. The actual superposition or piecing is performed on the clamping straight line of the detaching cylinder.
The guide roller, which is located after the front, only needs to guide the formed fiber fleece. Before a new detaching or piecing step can be performed again, the detaching cylinder, including the guide rollers, must be turned around, i.e. reversed. This causes the new end of the fiber fleece to be conveyed by a predetermined amount in the direction opposite to the separating direction. This return conveyance is caused by the fact that the detaching roller has to perform two operations: detaching and piecing. In this case, in addition, the desired overlap of the ends must take place. The fiber fleece conveyed intermittently as described above is separated through the separation table and the separation roller and reaches the funnel. Another pull-off roller pair is located behind the pull-off funnel.

[0003] With this known configuration, expensive combing slivers can be manufactured. Due to the required back step movement, the drive element, in particular the drive element for the detaching cylinder, must be very complex and stable. This is because a large acceleration takes place in a short time.

[0004] In order to reduce the amount of large mechanical drive elements that are to be moved, European Patent No.
In the specification of U.S. Pat. No. 7,723, it is proposed that the detaching roller is driven by an electric motor-driven device together with a guide roller disposed behind it. The use of an electric motor results in a good solution, which on the one hand saves on the mechanical transmission and on the other hand gives good adjustability. However, such drive motors are relatively expensive and the step-back movement must still be performed.

[0005] In order to separate the detaching from the piecing, that is, to reduce the work of the pair of detaching rollers, it has been proposed that the actual piecing process be performed by a guide roller disposed downstream of the detaching roller. Was. Such a device is described, for example, in DE 2430
No. 62 discloses it. The pair of detaching rollers shown here rotates regularly only forward without interruption. However, the piecing roller following it still performs a reversing movement or a step-back movement. Further, the positions of the pressing roller of the detaching roller and the pressing roller of the piecing roller are changed during the detaching step and the piecing step.

A similar device is known from DE 745 212 A1. Similarly in this case,
The detaching roller only rotates in one direction. The splicing roller or piecing roller still performs a step-back motion to perform the piecing process.

Furthermore, in the device known from EP-A-450 410, the piecing operation likewise requires
This is carried out by a pair of piecing rollers that is provided after the pair of data rollers. The piecing roller pair is configured such that a reversing movement is no longer required for the piecing process. In this case, the pair of piecing rollers is provided with a driven upper piecing roller which is arranged immovably on the frame. During the piecing process, the piecing roller is in contact with a pressing roller that is rotatable and liftable. In order to add a new fiber package to the end of the formed fiber fleece, the transport of the fiber fleece has to be interrupted in such a device based on a discontinuous detaching process. This is done by lifting the lower piecing roller away from the upper driven piecing roller. This interrupts the friction connection between the two rollers via the fiber fleece.
That is, the piecing roller lifted and separated from the lower side is brought into a rest state, whereby the unloading of the fiber fleece is also interrupted. This step is performed during each combing circle. The disadvantage of such a device is, on the one hand, the tedious movement of the lower piecing roller and, on the other hand,
It is the intermittent acceleration of the fiber fleece for carrying out the piecing process. As a result, the device is very susceptible to wear and the fiber fleece can be damaged in quality by constant acceleration.

[0008]

The object of the present invention is therefore to avoid the known disadvantages of the prior art, to increase the number of combing circles and to enable production with at least a comparable quality. Another object of the present invention is to provide a combing machine provided with a device for detaching and piecing.

[0009]

In order to solve this problem, according to the structure of the present invention, the driving of the detaching roller is performed in such a manner that the peripheral speed of the detaching roller relative to the peripheral speed of the piecing roller is different from the driving of the piecing roller. At least some sections of the entire combing circle are configured or controlled differently, the end of the formed comb sliver fleece being clamped on the piecing roller by a pressing roller during the entire combing circle, This ensures uninterrupted removal of the fiber fleece.

[0010]

By means of such a device, the discontinuous detaching process is compensated for by the different peripheral speeds of the detaching roller relative to the piecing roller, with a defined overlap or overlap. Uninterrupted removal of waste fiber fleece is assured. By appropriate selection of the peripheral speed, the desired overlap can easily be obtained.

In one configuration, the peripheral speed of the detaching roller and the peripheral speed of the piecing roller are constant, and the peripheral speed of the detaching roller is higher than the peripheral speed of the piecing roller. This makes it possible to easily configure the drive mechanism. Further, it has been proposed that the detaching roller is driven at a constant peripheral speed and the piecing roller is driven during a combing circle at a set variable peripheral speed. I have. further,
The front end of the separated and stretched fiber package is
In order to be able to splice without difficulty to the rear end of the fiber fleece held by the piecing roller,
It is proposed that at the time of the seaming process, the peripheral speed of the piecing roller is made approximately equal to the peripheral speed of the detaching roller. In this case, the expression "to the rear end of the fiber fleece" does not simply mean that the ends of the two ends are guided together. The front end of the newly supplied fiber package is placed at a distance from the front end of the fiber fleece so that both ends overlap or overlap by a predetermined length. It means that.

In another configuration, the detaching roller is driven in a combing circle at a set variable peripheral speed, and the peripheral speed of the piecing roller is kept constant. The peripheral speed of the detaching roller is set so that the peripheral speed of the detaching roller is substantially equal to the peripheral speed of the piecing roller at the start of the piecing step. Thereby, accurate delivery to the fiber fleece held by the piecing roller and a predetermined piecing distance can be obtained.

In order to prevent a new fiber package from being displaced during the transport between the detaching roller and the piecing roller, and to obtain an accurate joining process to the fiber fleece, the detaching roller and the piecing roller are used. In between, it is proposed that at least one guide means for the drawn and stretched fiber tufts, ie for a new fiber package, is arranged.

In this case, the guide means may be movably formed, for example, as a plate which is slidable in the longitudinal direction. If necessary, this plate
It may be formed so as to be rotatable about a rotation axis.

In order to allow the trailing end of the new fiber package to slide out of the guide means or the plate before another new fiber package reaches the guide means or the plate, it extends longitudinally in the direction of withdrawal of the plate. Has been proposed to be at least 25% shorter than the inner distance between the detaching roller and the piecing roller.

In a further embodiment, the fiber fleece guided on the guide means is at least partially covered on its surface. That is, the guide means is provided with a corresponding cover which extends above the actual guide surface. This, on the one hand, can prevent contamination and flight of the textile packages, which are more or less open,
The transport process can also be isolated from unwanted air circulation.

Such a means is furthermore advantageous if the guide means is formed as a hollow body open on both sides, viewed in the withdrawal direction, and is used for receiving the fiber fleece.

For good transfer of the fiber fleece to the end, it is proposed to make the hollow body pivotable.

In order to assist the conveying process in the area of the guide means, the guide means is provided with a compressed air device. The compressed-air device is formed in such a way that it can be transported simply or advantageously in the direction of the end of the fiber fleece.

In another configuration, the guide means is provided with an opening for applying a negative pressure. Such an arrangement can likewise be used to hold the fiber package on the guide means in place and for a certain period of time. Such devices are used, for example, in cage drums for transporting fiber fleece.

In order to obtain the desired piecing or overlap, it is proposed that the distance A between the detaching roller and the piecing roller be adjustable if the staple length to be processed is different. You.
This adjustment can be done stepwise or steplessly.

In order to obtain a precise coordination with the movement of the nipper unit, the drive of the detaching roller and / or of the piecing roller corresponds to the drive of the nipper unit.

A particularly advantageous arrangement with regard to adjustability is obtained if the detaching and / or piecing rollers are driven by separate drives by electric motors.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an embodiment of the present invention.

FIG. 1 shows a known prior art embodiment. In this known technique, a wrap web 2 supplied by a nipper unit 1 is supplied to a pair of detaching rollers 5 via a feed roller 3. The fiber tuft 7 projecting from the opened nipper 1 reaches the rear end 8 of the comb sliver fleece or the fiber fleece 10, and thereby reaches the clamp gap of the detaching roller 5 based on the forward movement of the detaching roller 5. . In this case, the fibers that are not retained by the wrap web retention or nipper are pulled away from the wrap web bundle. In this detaching step, the fiber tuft is additionally pulled by the needle of the top comb 9. With this top comb 9, the rear part of the separated fiber tuft is combed off to remove neps, impurities or the like. Based on the speed difference between the wrapping web 2 and the separating speed of the detaching roller, the separated fiber tuft is stretched to a predetermined length. The guide roller 6 is arranged following the pair of detaching rollers. In this detaching step, the front end of the drawn fiber package and the rear end 8 of the fiber fleece 10 overlap or overlap. As soon as the detaching or piecing process is completed, the nipper returns to the rear position. In this rear position, the nipper is closed and feeds the tufts 7 projecting from the nipper into the comb segments 12 of the round comb 13 for combing. Before the nipper unit 1 returns to the front position again, the detaching roller 5
The guide roller 6 performs a reverse rotation, whereby the rear end portion 8 of the fiber fleece 10 is returned and conveyed by a predetermined amount. This is necessary to obtain the necessary overlap for the piecing process.

FIG. 2 shows a portion of FIG. 1 of an embodiment according to the present invention. In this figure, for the sake of clarity, FIG.
Other units are omitted. In this figure, only the nipper unit 1 for supplying the lap web 2 to the succeeding detaching roller AW is shown. This pair of AWs is the actual driving roller W that is driven.
1 and a loaded pressure roller D1 located above the pressure roller D1. For the sake of clarity of the drawings, the pressing rollers are denoted by reference numerals D1 and D2 and the reference numerals of the detaching roller and the piecing roller are changed for the drawings of the embodiments described later.

A piecing roller pair LW is arranged at an interval A between the detaching roller pair AW. The pair of piecing rollers LW includes a driven piecing roller W2 which is arranged immovably on a frame, and a pressing roller D2 which is placed under pressure on the piecing roller W2.

As in the embodiment of FIG. 2 shown in FIG. 4, the peripheral speed U2 of the detaching roller W1 is constant, and is located above the peripheral speed U1 of the piecing roller W2. Similarly, the peripheral speed U1 of the piecing roller W2 also takes a constant course. FIG. 2 shows a fiber tuft 7 at the end of the wrap web 2.
Shows a state where the nip point K1 of the pair of detaching rollers AW is located. Due to the continuous rotation of the detaching roller W1, the fiber package 15 is pulled forward on the guide plate 17 from the pair of detaching rollers in the transport direction T. At the same time, the piecing roller W
By means of the two continuous drives, the end 20 of the fiber fleece 10 is
Are carried out in the transport direction T. A guide plate 21 may be provided for guiding the end 20. During the formation of the fiber package 15, the plate 17 moves to the position shown by the solid line in FIG. The end of the fiber package 15 reaches the rear end 20 of the fiber fleece 10 at a point P.
At this point, the rear end of the fiber package 15 may already be located outside the nip point K1, or the clamp may still be held. Both cases are conceivable, and if clamping is still taking place, the different circumferential speeds will cause small waves or slack to form in the fiber package 15.
The front end of the fiber package 15 is
At the nip point K2 of the piecing roller pair LW. As a result, the connection with the end portion 20, that is, the piecing is finally performed. Plate 1
7 moves further to the position indicated by the dash-dot line below, in which the end of the fiber package 15 released during this is still located in a partial area of the plate 17. When the plate 17 moves further to its original position in FIG. 2, the end of the fiber package 15 falls down and is completely placed on the end 20 of the fiber fleece. Thus, the plate 17 is again free to receive a new fiber package 15 created by the de-touching process of the de-touching roller pair AW. The spliced fiber fleece 10 delivered from the piecing roller is separated obliquely and formed into a sliver 24 via a funnel 22. This sliver 24 is guided to a subsequent drawing machine in a known manner for further processing. The above cycle,
That is, the detaching and the piecing in the combing circle are newly performed again.

FIG. 5 shows a spliced fiber fleece 10.
Is schematically shown. In this figure, the piecing distance is indicated by the symbol Ue. The fiber package 15 having a length L here consists of a region having a length L1. This area is the supply amount of the nipper in the combing circle, which has been doubled by the draft by the pair of detaching rollers. The remaining portion L-L1 corresponds to the length of the longest fiber still drawn from the wrap 2 at the end of the detaching step.

FIG. 6 shows another embodiment. In this embodiment, a fixed plate 2 is used as a guide means.
6 are used. The plate 26 has a length L2, which is significantly shorter than the inner distance LL between the pair of detaching rollers and the pair of piecing rollers. In the embodiment of FIG. 6, the detaching roller W11 has a variable peripheral speed, and its maximum value is U2. The piecing roller W22 is driven at a continuous peripheral speed U1. This is particularly clear from FIG. It is apparent from FIG. 7 that the detaching process of the detaching roller W11 is started at the point FA. That is, at this point, the detaching roller W11 has a required detaching speed. As a result, as already described in the previous embodiment, the fiber tuft 7 is stretched, thereby forming a fiber package 15 and the fiber package 15 is formed.
Is moved forward through the plate 26 in the direction of the piecing roller pair LW. The front end of the fiber package 15 reaches and is entrained by a continuously drawn end 20 of the fiber fleece 10. This is particularly evident from the further method steps shown in FIG. In this case, the rear end of the fiber package 15 is still only partially mounted on the plate 26,
After a short time, it is lowered by the continuous forward movement of the piecing roller W22 and completely rests on the trailing end 20 of the fiber fleece 10. The downward movement of the end of the fiber package 15 is aided by the additional application of a negative pressure in the lower region. As soon as the plate 26 is free again, the trailing of the new fiber package 15 can be carried out again. As can be seen from the embodiment of FIG. 6 or the embodiment of FIG. 8, the adjustability of the spacing A is schematically illustrated. FIG. 6 shows a carrier 28 in which a piecing roller W22 and a pressing roller D
2 are guided. In order to adjust the spacing A, the carrier 28 can be moved in accordance with the schematically illustrated hole pattern and can be newly fixed.
FIG. 8 shows the stepless movement of the carrier 28. In this case, the movement can be performed by the control cylinder 30. In this case, the carrier 28 is guided accordingly (not shown). Similarly, as can be seen from FIG. 8, the formed fiber fleece 10 is formed into a sliver 24 via a funnel 22 by oblique drawing.

In the alternative embodiment of FIG. 9, instead of a single plate, a pivotable double plate 32 is used which is pivotally arranged about a pivot point 34. A device for adjusting the pivoting of the double plate 32 is not shown for the sake of clarity of the drawing, which can be easily formed from known mechanisms. The wrap web 2 supplied from the nipper unit 1 or the fiber tuft 7 projecting from the nipper unit 1 is delivered to the nip point K1 of the pair of detaching rollers, and is stretched to become the fiber package 15 as described above. This fiber package 15 reaches between the double play and the 32 parallel plates, where it is moved in the direction of the piecing roller pair LW. As can be seen from FIG. 10, in the embodiment of FIG.
Alternatively, the detaching roller W12 has a continuous peripheral speed U2.
have. Conversely, the piecing roller W23
Has a variable peripheral speed U1. These peripheral speeds U
1 and U2 coincide at the point FUe. This point FUe is also the time when the front end of the fiber package 15 meets the rear end 20 of the fiber fleece 10. Fiber package 15
Leaves the nip point K1 and the rear end 20 of the fiber fleece 10.
Is moved in the direction of the nip point K2. The double plate 32 is again released from the fiber package 15 and the double plate 32 is pivoted clockwise about the pivot point 34 to accommodate a new fiber package,
The front opening of the double plate 32 is directed downward. The back end of the fiber package 15 is fed downwardly from the area of the double plate 32 by the aid of the negative pressure indicated schematically by the dashed arrow, and is completely placed on the end 20 of the fiber fleece 10. After that, the double plate 32 again
It is turned back to its original position shown in FIG. 9 and is ready to accommodate a new fiber package 15.

Due to the difference in the drawing-out movement of the piecing roller LW, the fiber fleece cannot be supplied to the funnel for forming the sliver without difficulty, and the drawing-out roller 36 must be additionally mounted. The pull-out roller 36 continues to supply the gathered fiber fleece to the funnel 22 for forming the sliver 24.

FIG. 12 schematically shows a drive diagram for an arrangement according to the invention. In this figure, an additional embodiment is shown having a guide element in the form of a pivotable plate for transporting the fiber package 15. The driving force is transmitted to the transmission G by the main motor M. Drive Strands (Antrieb)
The nipper 1 is reciprocated through the slang 60. The drive of the round comb 13 is simultaneously connected to the nipper drive and is schematically illustrated by a drive strand 62. A pair of detaching rollers A via the drive strands 64 and 65 transmitted by the transmission G
W or the piecing roller pair LW is driven. In this case, it is necessary that the driving device for the nipper or the driving device for the round comb be mechanically connected. A transmission 67 is additionally connected to the drive strand 64. Via this additional transmission 67, the rotational speed of the detaching roller and thus the draft can be varied. Further driving possibilities are indicated by alternate long and short dash lines. In this case, the pair of detaching rollers or the pair of piecing rollers are electrically driven individually by the motors M1, M
2 driven. The two motors M1, M2 and the main motor M are electrically connected to each other via the control device 70. In order to allow the detaching roller AW or the piecing roller LW to move synchronously or simultaneously with the movement of the nipper or the round comb, the round comb 13 via the sensor 72 and the lane 73.
Is scanned and transmitted to the controller 70.
This guarantees synchronous movement via the control device.
