Description

Technical area

The invention relates to a multiple nozzle connection of a suction line of a textile machine according to the independent patent claim and to a textile machine equipped therewith.

State of the art

A large number of designs are already known from practice, a compression device being arranged downstream for compacting (compressing) the fiber material (fiber strand) discharged from a drafting unit. Subsequent to such a compression device, the compressed fiber material is fed to a twist generating device after passing through a clamping point. Such a twist generating device consists, for example in a ring spinning machine, of a rotor which revolves on a ring, the yarn produced being wound onto a rotating tube. The compression devices used are essentially circumferential, perforated suction drums or circumferential aprons provided with perforations. A special suction area is defined on the compression element using appropriate inserts within the suction drum or within the circumferential aprons. Such inserts can, for example, be provided with appropriately shaped suction slots, to which a negative pressure is applied, whereby a corresponding air flow is generated on the periphery of the respective compression element. This air flow, which is oriented essentially transversely to the direction of transport of the fiber material, in particular also binds protruding fibers into the yarn.

In the known solutions, the fiber material discharged from the drafting unit is guided above or below the compression devices used. Particularly when used on a ring spinning machine, it is necessary to provide an additional clamping point after the suction zone in order to obtain a twist lock.

Such facilities are for example in the publications EP947614B1 , DE102005010903A1 , DE19846268C2 , EP1612309B1 , DE10018480A1 or the CN1712588A shown and described. The aforementioned publications are essentially compaction devices which are permanently installed in connection with the respective drafting system. These compaction devices are partially driven by special drive shafts arranged over the length of the spinning machine, which are either in drive connection with a suction roller or a rotating belt or via permanently installed drive connection to correspondingly arranged pressure rollers of the compaction device.

CN101275316 comprises a draft device with a cotton suction wind pipe, an aggregation pipe, a cotton suction pipe and a multi-channel connecting pipe, with channels on one side of the multi-channel connecting pipe being connected to the cotton suction wind pipe. One of the channels on the other side of the multi-channel connecting pipe is connected to the cotton suction pipe. The other channels are connected to the aggregate pipe.

EP2573227 discloses a drafting system, a spinning unit and a spinning machine. DE9015353U1 discloses a device for sucking off fiber material on textile machines. Several suction channels are connected to form a suction flute.

In practice, there is a requirement to retrofit existing spinning machines with a conventional drafting unit with such a compression device in order to ensure the possibility of producing high-quality yarns with these machines as well. Devices have therefore been proposed with which conventional drafting systems can be retrofitted with such a compression device. Such is for example from the DE10227463C1 to be taken, whereby the punch of the drafting unit is extended in order to store an additional drive roller. The drive roller, which extends over the entire length of the spinning machine, is intended to drive the retrofitted compacting device. The attachment and installation of such a retrofit is very time-consuming and inflexible, ie if you want to dismantle it to a normal drafting system without a compression device, a very high expenditure of time is again necessary.

In the published DE10050089A1 an embodiment with a compaction device is shown, which is intended for subsequent attachment to a conventional drafting system.

From the CN2851298Y a device is known in which a compaction roller with a rotation lock roller is received in a bearing element which is connected via a plate via screws to a pivotable loading arm of a drafting device. In the assembled and locked position, the drive is in this case via friction from an output roller connected directly to a drive and the pressure roller assigned to it on the compaction roller and the Transfer lock roller. The compression device shown here is also intended for subsequent attachment to existing drafting equipment of spinning machines without compression. The attachment of the compression unit shown here to an existing drafting unit via a screw connection, as well as the threading in the axis of the pressure roller is relatively time-consuming and requires additional adjustment of the distances. In addition, the connection to a vacuum source must also be established separately.

In the embodiments described above, the suction elements, which are assigned to a defined compression area for compressing the fiber material, are subjected to a negative pressure via additionally arranged lines which are connected to a negative pressure source.

In order to simplify such compression devices, whereby a simple and quick installation on conventional drafting units is made possible without additional drive elements having to be installed, in the WO2012068692A1 proposed an embodiment, wherein the compression element in the form of a suction drum and the pinch roller are rotatably mounted on a support element. The support element is attached to the spinning machine in a removable manner by means of attachment means. In order to establish a drive connection between the drafting system rollers and the demountably attached compression device, the compression device is pivoted about a pivot axis in the direction of the pair of output rollers of the drafting system via the support element, with a friction wheel attached coaxially to the respective suction drum and the lower roller of the pair of output rollers of the drafting system being a frictional connection ( via friction). The compression device is held in this drive connection by appropriately arranged spring elements (e.g. on the loading arm of the drafting system). To make the drive of the compression device more flexible suggests WO2012068692A1 furthermore, a second gear stage is provided between the drive element of the compression element of the first gear stage and the compression element.

The disadvantage of this embodiment, however, is that converting the textile machine from a compression device to a conventional thread suction device is relatively costly and time-consuming.

Ways of Carrying Out the Invention

Figure 1 shows a schematic side view of a spinning station 1 of a spinning machine (ring spinning machine) with a drafting unit 2, which is provided with an input roller pair 3, 4, a central roller pair 5, 6 and an output roller pair 7, 8. A strap 12, 13 is guided around the center rollers 5, 6, each of which is held in its position shown around a cage (not shown in detail). The upper rollers 4, 6, 8 of the mentioned roller pairs are designed as pressure rollers which are rotatably mounted on a pivotably mounted pressure arm 10 via the axes 4a, 6a, 8a. Two adjacent drafting units 2 (twin drafting units) are assigned to a pressure arm 10. The pressure arm 10 is mounted pivotably about an axis 15 and, as shown schematically, is acted upon by a spring element 9. This spring element can also be an air hose, for example. The rollers 4, 6, 8 are pressed against the lower rollers 3, 5 and 7 of the roller pairs via the spring loading shown schematically. The roller pairs 3, 5, 7 are driven by a drive, not shown. Individual drives as well as other types of drive (gear wheels, toothed belts, etc.) can be used. Via the driven lower rollers 3, 5, 7, the pressure rollers 4, 6, 8 or the apron 13 are driven via friction via the apron 12. The peripheral speed of the driven roller 5 is slightly higher than the peripheral speed of the driven roller 3, so that the fiber material 11 fed to the drafting unit 2 in the form of a sliver between the input roller pair 3, 4 and the center roller pair 5, 6 is subjected to a pre-draft. The main draft of the fiber material 11 takes place between the central roller pair 5, 6 and the output roller pair 7, 8, the output roller 7 having a significantly higher peripheral speed than the central roller 5.

The drawn fiber material 11 discharged from the respective pair of output rollers 7, 8 is deflected downward and reaches the area of a suction zone 16 of a subsequent suction drum 17 which is part of the compression device 46b according to the invention. The respective suction drum 17 is provided with perforations or openings 39 running on its circumference. Following the suction zone 16, a clamping roller 18 is provided for each of the suction drums 17, which rests on the respective suction drum 17 via a pressure load and forms a clamping line with it. The respective pinch roller 18 is rotatably mounted on an axis 19, which in a Guide slot 20 of a U-shaped receptacle of a pressure arm 21 is held. The axis 19 is slidably mounted within the guide slot 20 transversely to its longitudinal axis. A plunger protrudes into the guide slot 20 through an opening in the pressure arm 21, which rests on the outer circumference of the axle 19 and is acted upon by a pressure spring 22 shown schematically. The opening is attached approximately in the middle at the end of the guide slot 20 and opens into a substantially closed cavity of the pressure arm 21, in which the compression spring 22 is arranged. This is supported at the closed end of the cavity and the opposite end rests on a head of the plunger.

The pressure arm 21 is mounted pivotably about an axis attached to its end in a bearing element. In this swivel position, the axes are shown schematically in Fig. 1 The stop edge shown is held transversely to its pivot axis at the end of a respective guide. Via the force of the compression spring 22, the pinch rollers 18, which are rotatably mounted on the pressure arm 21, are then loaded against the respective suction drum 17, the pinching line being created. The pressure arm 21 is pivoted past dead center until it rests on a stop. In this position, the axis 19 of the pinch rollers 18 is below the plane which runs through the pivot axis and the central axis of the suction drums 17, ie the pinch roller 33 is held in this position above dead center. Further details relating to the attachment and design of the pinch rollers 18 can be found in FIG CH705308 can be removed.

The pressure lever 10 is then pivoted about its pivot axis 15 from an upper position, shown in dashed lines, to a lower position, in which a pressure force is exerted on the compression device 46b in FIG Direction of the roller 7 is exerted. The suction drum 17 connected to it is driven by the roller 7 via friction via a drive element 40 described further below.

In this "operating position", the fiber material 11 drawn and discharged by the drafting system 2 is fed to the subsequent suction zone 16 of the respective suction drum 17 and compressed in a known manner under the influence of the suction air flow generated. A deflecting screen arranged at a distance can also be attached above the suction zone 16 be, for example in the DE4426249 is shown and described. This publication also describes the process of compaction of the fiber material.

To generate the required negative pressure in the area of the suction zone 16, a negative pressure source 26 is provided, which is connected to a central suction channel 27. The suction channel 27 is connected via a line 28, a flexible multiple nozzle connection 29, to the respective end of the suction channel 31 of the compression device 46b protruding in the direction of the suction channel 27. The flexibility of the multiple nozzle connection 29 enables the compacting device 46b to pivot about an axis. For this purpose, the compression device 46b has two lateral protrusions 30, which in relation to one another Fig. 2 Intervene explained holder. The multiple nozzle connection 29 shown schematically can be designed in such a way that, when two half-shells are joined together, it is connected to a suction channel 31 in a form-fitting manner and tightly to the outside. The construction and assembly of the half-shells in such a support element are from the WO2012068692A1 known. The spinning machine can advantageously be retrofitted with the compression device 46b. The structure, the mode of operation and advantages of the multiple nozzle connection 29 according to the invention are shown in FIG Fig. 2 explained in more detail.

The pinch line generated by the pinch roller 18 simultaneously forms a so-called "rotation blocking gap", from which the fiber material 11 is fed in the conveying direction in the form of a compressed yarn 32 with rotation to a schematically shown ring spinning device. This is provided with a ring 33 and a rotor 34, the yarn being wound onto a sleeve 35 to form a bobbin 36 (cop). A thread guide 37 is arranged between the nipping line and the traveler 34. The ring 33 is attached to a ring frame 38 which moves up and down during the spinning process.

FIGS. 2 and 3 show the multiple nozzle connection 29 according to the invention. It is used for the alternative connection of a compression device 46b, as shown in FIG Fig. 1 in context was explained with a ring spinning machine, or for connecting a suction pipe device 46a to the suction channel 27 of the ring spinning machine.

Fig. 2 shows the multiple nozzle connection 29 according to the invention with a suction pipe device 46a connected to the suction channel 27 of the ring spinning machine. The suction device 46a consists of two suction pipes 47 which are arranged next to one another and which are connected via a central, round connecting element 50. A second connection between two suction pipes 47 is located at the front end of the suction pipe device 46a. The universal multiple nozzle connection 29 has a connection piece 42 with three connections 43 located next to one another, which are used depending on the connected device. An adapter or spacer 44, which can be connected to the connections 43 of the connecting piece 42, and a seal 45 are located between the connections 43 and the pre-sealing device or the suction pipe device 46a lateral connections 43 are closed. A suction tube device 46a can be connected to the lateral connections 43, the middle connection 43 then being closed by a plate 48.

The compacting device 46b ( Fig. 1 , 3 ) or the suction tube device 46a ( Fig. 2 ) are detachably held by a holder of the multiple nozzle connection 29. In the exemplary embodiment shown, the holder consists of two spaced apart holding elements 49. The suction pipe device 46a engages with the round connecting element 50 in the spaced apart holding elements 49, there is a detachable connection, for example a clip connection. The holding elements 49 are fastened to a holding profile 51 of the textile machine and at the same time hold the adapter or spacer 44 in place.

Fig. 3 shows the multiple nozzle connection 29 according to the invention with a connected compression device 46b, as shown in FIG Fig. 1 was explained in connection with a ring spinning machine. The universal multiple nozzle connection 29 corresponds to the design of Fig. 2 , it has the three connection pieces 42 with the three connections 43 located next to one another. An adapter is located between the connections 43 and the pre-sealing device or the suction pipe device 46a or spacer 44, which can be connected to the connections 43 of the connecting piece 42, and a seal 45. For fastening purposes, the compression device 46b has two lateral protrusions 30 which engage in the two elements 49 of the holder. The compression device 46b can be connected to the central connection 43, the side connections 43 then being closed by plates 48.

Fig. 4 shows a section AA through the multiple nozzle connection 29 with a connected suction device according to FIG Fig. 2 . The compression device 46b and the suction pipe device 46a can be pivoted about the aforementioned axis and can thus be releasably attached to the connection piece 42 by a rotating or tilting movement. The suction device 46a can assume two positions by means of two latching lugs 52, whereby in an upper position the suction pipes 47 are aligned at right angles to the suction channel or in alignment with the multiple nozzle connection and in a lower position the suction pipes 47 are inclined slightly downwards compared to the upper position are (not shown).

The embodiment according to the invention is advantageous because the machine can be easily converted. The invention also relates to a method for releasably fastening the compression device 46b or the suction pipe device 46a to the multiple nozzle connection 29 of a textile machine, in particular a ring spinning machine.
