Abstract

A textile machine is described with a multiplicity of machining points for treating and winding up a multiplicity of threads. Each of the machining points here has a plurality of delivery mechanisms (3, 9, 14) for drawing off and guiding the threads (11), and a winding-up device (10.1). The winding-up devices (10.1-10.9) are arranged next to one another and above one another along the longitudinal side (39) of the machine. In order to change the reel, the winding-up points are assigned auxiliary means (22.1-22.2) which have thread suction means (16) which, during a change of the reel, pick up the threads (11) of one group of winding-up devices (10.1-10.3) and conduct them away. In order, during the simultaneous conducting away of a plurality of threads, to obtain secure guidance of the threads in the devices connected upstream of the machining points, according to the invention a group of pneumatic conveying means (15.1-15.3) is arranged in the thread run upstream of the group of winding-up devices (10.1-10.3) assigned to one of the thread suction means (16), said conveying means being designed such that they can be controlled collectively in order to carry out the changing of the reel.

Description

textile machine

The invention relates to a textile machine with a plurality of processing stations for treating and winding a plurality of threads according to the O-berbegriff of claim 1.

A generic textile machine is known from US 2,206,834.

In the known textile machine, a plurality of winding devices are arranged side by side and one above the other on a machine longitudinal side. In each of the winders, a thread is wound into a spool. For this purpose, the thread is fed continuously in each of the processing points by supply plants of the take-up device. The winding of the threads is continuous until the wound bobbin has reached a maximum bobbin diameter. In the take-up device, a bobbin change is now to be carried out, wherein aids for carrying out the bobbin change are provided. Such auxiliaries have at least one thread suction means in order to receive the continuously fed threads during the changing operation and usually to lead them to a yarn waste container.

In the known textile machine several Aurwickeleinrichtungen are associated with a thread suction, which is directly connected to a Garnabfallbehälter. In this case, a plurality of threads are taken up by the thread-suction means at the same time, so that the take-up devices assigned to the threads are ready for a bobbin change. In this case, it must be ensured that sufficient yarn tension is maintained during the removal of the threads in order to ensure reliable guidance of the thread in the processing points. The severing of the threads as well as the transfer to the thread suction means usually takes place in the known textile machine by an operating person, who then performs the bobbin change in the take-up.

From WO 03/004742 Al a textile machine is known in which the plurality of winding devices are associated with tools to perform automated bobbin change without intervention of an operator can. For this purpose, as auxiliaries per take-up a thread suction, a release agent and a take-up pneumatic conveying means are used. The pneumatic conveying means has a guide tube with a blowing end, through which the thread is guided during initial application in the winding device. The take-up device provided release agent and thread suction are used for bobbin change. Thus, in each of the winders an individual bobbin change can be performed. Such textile machines therefore require a greater outlay on equipment for designing the aids in order to carry out individual bobbin changes per take-up device.

The invention has the object, a textile machine of the generic type, in which several threads of a group of Aufwickeleinrichtun- conditions simultaneously absorbed and removed by a thread suction during the bobbin change, to improve so that even when using Umschlingungswerken in the processing stations a secure Thread guide is guaranteed.

A further object of the invention is to provide a textile machine with a plurality of processing stations, in particular for false twist texturing, in which manual bobbin changing can be carried out effectively and quickly.

The object is achieved by a textile machine with the features according to claim 1. Advantageous developments of the invention are defined by the features and feature combinations of the subclaims.

The invention has the advantage that the thread tensile forces generated on the threads by the thread suction means are designed essentially only for the removal of the threads. The thread tension forces required to convey and maintain thread guides of the associated processing stations are generated by a group of pneumatic conveying means. For this purpose, a group of pneumatic conveying means is arranged upstream of the group of winding devices, which are assigned to one of the thread suction means, in the course of the thread. To carry out the bobbin change, the pneumatic conveying means associated with the group of winding devices can be collectively controlled, so that the activation of all conveying means can be carried out in a simple manner by an operating person. Depending on the number of take-up devices which are associated with a thread suction means, two, three or four conveying means can thus cooperate simultaneously with the thread suction means. Thus, a larger number of threads can be safely absorbed by a thread suction and discharged to a Garnbehälter.

In order to avoid in particular a Fadenverschlappung of those of the winding upstream upstream delivery, according to an advantageous embodiment of the invention, the pneumatic conveying means are arranged in the processing stations in the yarn path between the take-up and the associated delivery mechanisms. Thus, the short-term Fadenverschlappungen possibly occurring during the yarn transfer to the thread suction can be safely prevented from the delivery works.

In order to enable the most gentle possible thread guidance in the processing stations, the delivery mechanisms can be formed by one delivery shaft or several delivery shafts, on which the threads are provided with at least one multiple partial transfer belt. be led looping, so that advantageous clamping and conveying gaps for conveying and guiding the threads are avoided.

In order to facilitate the creation and the promotion of a thread in the processing point by the pneumatic conveying means simple manner, the development of the invention is preferably used, in which the pneumatic conveying means are each formed by a Fadeninjektor having a slotted guide channel with a suction and having a bubble end. The guidance of the thread within the guide channel can be improved in such a way that a thread guide is formed directly at the suction end and at the bladder end.

In order to activate the pneumatic conveying means, the pneumatic conveying means associated with a group of winding devices can be connected to a compressed air source jointly by means of an adjusting means. Thus, by actuating the actuating means, each of the connected pneumatic conveying means can be activated simultaneously.

The pneumatic conveying means can also be used advantageously for the first application of the threads in the processing stations. To improve the thread guidance during the bobbin change and when first applying the threads in the processing points, the development of the invention is particularly advantageous, in which a plurality of delivery mechanisms associated funding are provided within the individual processing points, which are activated when creating a thread and / or a bobbin change. Thus, a minimum yarn tension required to guide the yarns is maintained throughout the processing station. In particular, thread entanglements behind the delivery mechanisms can thereby be avoided.

As thread suction preferably Stelleniηjektoren be used, which are connected with a blowing end to a Garnabfallbehälter. Leave it 5 011355

Also, several threads advantageously dissipate to a Garnabfallbehälter. Each group of take-up devices is assigned a job injector.

For further optimization and design of the aids, the development of the invention is particularly advantageous, in which the thread suction means are formed alternately by a movable trained Stelleninjektor, which is connected with a blowing end to a yarn container. The job injector is alternately fed to the individual groups of winders to allow the bobbin changes.

In order to realize as short as possible guide paths for yarn waste, the job injector and the Garnabfallbehälter is preferably combined into a mobile control unit, wherein the control unit is held by guide means on a machine longitudinal side parallel to the winding devices movable. Thus, an operator may optionally position the tools required for the bobbin change to the group of winders in which bobbin changes are to be made.

The guide means is preferably formed above or below the Aufwi- ckeleinrichtungen, the control unit is assigned to each of the side by side along the guide means winding a parking position. The parking position of the operating unit is selected such that at least one group of take-up devices can be operated to change bobbins.

The compressed air supply to the Stelleninjektor on the control unit can be advantageously formed by pressure ports that are distributed to the parking positions and can be coupled to the control unit.

For further optimization, it is proposed to form a plurality of position injectors on the operating unit, so that a plurality of groups of parking positions can be selected from one parking position P2005 / 011355

Winding devices are operable. Thus, the cost of moving the operating unit can be minimized on a machine longitudinal side.

In order to re-apply the threads individually into the wind-up devices after a yarn change has taken place, the yarn-suction means comprise an additional yarn-suction gun with which the threads can be manually guided by the operator. The yarn suction gun is preferably linked directly to the control unit and connected via a discharge hose to the Garnabfallbehälter.

The invention will be explained in more detail with reference to some embodiments of the textile machine according to the invention with reference to the accompanying figures.

7 shows schematically a view of a pneumatic conveying device FIG. 8 shows a schematic cross-sectional view of the pneumatic conveying device from FIG. 7 In Figs. 1 and 2, a first embodiment of the textile machine according to the invention is shown. 1 shows a cross-sectional view of the textile machine, which consists of a multi-part machine frame 7, wherein the frame parts of the machine frame 7 form an access passage 21. Immediately adjacent to the machine frame 7, a gate frame 6 is arranged, which contains a plurality of original positions with feed bobbins 2.

The textile machine has in the longitudinal direction - in FIG. 1, the plane of the drawing is equal to the transverse plane - a plurality of processing points to texturize a thread in each processing point. The Aurwickeleinrichtungen within the textile machine occupy a width of three processing points, so that each three Aufwickeleinrichtungen 10.1, 10.2 and 10.3 are arranged in a stacked manner in a column one above the other in the machine frame 7.

The cross-sectional view shown in Fig. 1 thus represents the yarn path in one of the processing points, 11 devices required for pulling, guiding, handling and winding of the thread on the machine frame 7 to a gangway 21 teilumschließenden yarn path are arranged.

Below, the facilities are briefly described by means of the yarn path in a processing station. For removing the thread 11 in the processing station of a gate frame 6 held in the supply spool 2, a first delivery mechanism 3 is provided. The first delivery plant is referred to in this case as deduction delivery 3. The deduction delivery unit 3 is followed in the yarn path by a heating device 4, a cooling device 5, a texturing device 8, a draft delivery device 9, a turbulizer 13, a pre-set delivery mechanism 20, a set heater 19, a set delivery mechanism 14 and one of the winders 10.1 to 10.3. The abovementioned devices can hereby be designed and driven as individual units per processing point or as multiple units for a group of processing stations. The stackers 10.1 to 10.3 arranged one above the other from three adjacent processing stations each comprise a coil holder 18, on which a coil 12 is held and wound, which is driven via a drive roller 17 during winding. The drive roller 17 is arranged in the yarn path of a traversing device, not shown here, which reciprocates the thread before filing on the spool within a traverse stroke and forth, so that a cheese is wound in the winding device.

For further explanation of the winding devices, reference is made at the same time to Fig. 2 in addition to FIG. FIG. 2 shows a view of the take-up devices arranged along a machine longitudinal side 39, wherein only the first nine take-up devices 10.1 to 10.9 are shown in FIG. The machine longitudinal side 39 extends parallel to the operation gear 21, out of which an operator performs the bobbin change on the winding devices 10.1 to 10.9.

The winding devices 10.1 to 10.9 are associated with a plurality of aids 22.1 to 22.3, through which the implementation of the bobbin change is possible. The tools 22.1 to 22.3 are each assigned to a group of winding points, so that the tools 22.1 are assigned to the winding points 10.1 to 10.3, the tools 22.2 to the winders 10.4 to 10.6 and the tools 22.3 to the winders 10.7 to 10.9.

The aids 22.1 to 22.3 are of identical construction, so that only the aid 22.1 will be explained in more detail below. The aid 22.1 contains a thread suction means 16 for receiving the threads during the execution of a bobbin change. The thread suction means 16 is in this case formed by a position injector 23.1. The Stelleninjektor 23.1 is located in the upper part of the winding devices 10.1 to 10.3. The Stelleninjektor 23.1 is connected to a blowing end to a pipe 24, which opens into a yarn waste container, not shown here. The compressed air supply of the job jektors 23.1 effected via a separate line, the ge with a pressure line 25 is coupled ^¬ through which a pressurized air is provided. The sow ^¬ constricting the Stelleninjektors 23.1 forms Eirie suction opening for receiving the takeup devices 10.1 to 10.3 threads associated. 11

In the lower part of the take-up devices 10.1 to 10.3, the aid 22.1 has a plurality of pneumatic conveying means 15.1 to 15.3. The conveying means 15.1 to 15.3 are each arranged in the yarn path to convey the yarn 11. In this case, the conveying means 15.1 is associated with the winding device 10.2, the conveying means 15.2 of the winding device 10.3 and the conveying means 15.3 are associated with the winding device 10.1. The conveying means 15.1 to 15.3 are in each case arranged between the take-up devices and the upstream set delivery mechanisms 14. The conveying means 15.1 to 15.3 are each connected via a compressed air connection with a control means 35.1. The adjusting means 35.1 is connected to a compressed air line 36. In this connection, a connection between the compressed air line 36 and the compressed air connections of the conveying means 15.1 and 15.3 can be established by the adjusting means 35.1. The conveying means 15.1, 15.2 and 15.3 thus form a group which is activated or deactivated synchronously by the adjusting means 35.1.

In the illustrated embodiment of the textile machine, the superposed in the machine frame winding devices are each combined into a group in which the threads are removed together during a Spulwechsels by the thread suction. In the operating situation illustrated in FIG. 2, straight bobbin changes are carried out in the winders 10.1 to 10.3. In this case, the adjusting means 35.1 to release the compressed air supply of the conveyor 15.1 to 15.3 is activated before the start of the bobbin change. Thus, the threads are funded by the set delivery mechanisms 14 pneumatically by means of compressed air after the expiration. Now, the bobbin change can be initiated by an operator takes the winder 10.1 to 10.3 associated threads and severed and then with the help of Transferring deflection in the mammal opening of Stelleninjektors 23.1. The threads 11 are continuously taken up only via the Stelleninjektor 23.1 and passed through the pipe 24 to a Garnabfallbehälter.

The 4.10 to 9.10 fed ^¬ arranged in the adjacent groups of takeup devices aids 22.2 and 22.3 remain inoperative. The adjusting means 35.2 and 35.3 are in the closed position, so that the associated conveying means 15.4 to 15.9 remain without conveying action. Similarly, the Jobietajektoren 23.2 and 23.3 remain inactive. The valves provided for actuating the position injectors 23. 1 and 23. 2 are not shown in greater detail here. Usually also manually operated position valves are used here.

In the exemplary embodiment of the textile machine illustrated in FIGS. 1 and 2, so-called godet delivery mechanisms are provided as delivery mechanisms, in which each delivery mechanism is formed by a single driven delivery shaft with an associated auxiliary pulley in each processing point. In FIG. 2, the delivery shafts 31.1, 31.2 and 31.3 of the set delivery mechanisms 14 of the first three processing points are shown for this purpose. Each of the delivery shafts 31.1 to 31.3 is assigned a drive. With such Umschlingungslieferwerken a particularly gentle thread guide can be realized, so that the textile machine shown in Fig. 1 and 2 is particularly suitable for false twist texturing of synthetic threads.

FIGS. 3 and 4 show a further embodiment of a textile machine, and FIG. 3 shows the embodiment in a cross-sectional view and in FIG. 4 in a partial view of the machine longitudinal side. Unless express reference is made to any of the figures, the following description applies to both figures.

The embodiment is essentially identical to the previous embodiment according to FIGS. 1 and 2, so that at this point only the subordinate be explained. The exemplary embodiment also has a multiplicity of processing points in order to stretch and text a submitted thread 11 in each case. For this purpose, a withdrawal delivery unit 3, a heating device 4, a cooling device 5, a texturing device 8, a stretch delivery device 9, a set delivery mechanism 14 and a winding device 10.1 are arranged in the processing station in the processing station. The delivery mechanisms 3, 9 and 14 are each formed by a continuous delivery shaft 31, on the circumference of which two mutually spaced follower rollers are held. The axles can be looped directly from the thread, so that when multiple wrapping of the thread, the delivery shaft partially entwines. However, it is also possible to form the delivery mechanisms 3, 9 and 14 as so-called Klemmlieferwerke, in which the Beilaufrollen lead a belt that holds the thread on the circumference of the delivery shaft.

Regardless of the design of the delivery mechanisms, the take-up devices are arranged one above the other in the form of a stack and are held in a plurality of side by side along the machine longitudinal side 39. In this case, the tools 22.1, 22.2 and 22.3 assigned to the groups of the take-up devices 10.1 to 10.9 comprise a common operating unit 40, which is arranged above the winding devices 10.1 to 10.9 and can be guided by means of guide means 42 along the machine longitudinal side 39. In Fig. 4, the first 18 take-up devices 10.1 to 10.18 are shown. As a guide means in this case a guide rail 43 is provided, in which the operating unit 40 is guided. The operating unit 40 has a Garnabfallbehälter 28, to which a plurality of pipes 29.1, 29.2 and 29.3 are connected. The pipes 29.1 to 29.3 have at their free ends in each case acting as a thread suction agent Stelleninjektor 38.1, 38.2 and 38.3. The Stelleninjektoren 38.1, 38.2 and 38.3 have a distance from each other, which is substantially equal to the pitch of the web-shaped arranged winding devices 10.1, 10.4, 10.7. For compressed air supply of the position injectors 38.1 to 38.3, these are connected via separate lines to a compressed air supply 26, which is an operating unit 40 is formed. The Compressed air supply 26 can be coupled in a parking position with an opposite pressure port 30.1.

In Fig. 3, by way of example only the first 18 take-up devices are shown. In this case, the three superposed Aufwickelinrichtungen 2xι a group are summarized, so that a total of six groups of take-up devices are shown by way of example. Along the machine longitudinal side 39 several parking positions for the operating unit 40 are provided. In Fig. 3, the first two parking positions are shown. In the first parking position, the operating unit 40 operates the first three groups of the take-up devices 10.1 to 10.9. The adjacent parking position thus represents the position of the operating unit 40 (shown in dashed lines) in order to serve the next three groups of Aurwickeleinrichtungen during the Spulwechsels.

The operating unit 40 further has a thread suction gun 47 which is connected via a discharge hose 48 to the Garnabfallbehälter 28. The compressed air supply of the thread suction gun 45 via a separate line which is connected to the compressed air supply 26.

In the lower region of the take-up devices, between the take-up devices 10.1 to 10.3, a group of conveying means 15.1 to 15.3 are arranged in each case, which are to be connected together by the actuating means 35.1 optionally with a compressed-air source. The mode of operation and the design of the aids provided in the lower region are therefore identical to the preceding exemplary embodiment, so that reference is made to the preceding description.

In the embodiment shown in FIG. 3, the conveying delivery unit 9 is followed by a further conveying means 37 for each processing point. The conveyor 37 also serves for pneumatic conveying of the thread in the processing station. The additionally arranged in the processing stations conveyor 37 are needed in particular for the first application of the thread in the processing station. Due to the use of wrapping supplies, it must be ensured during the application of the thread in the processing station that a slipping on the outlet side of the delivery mechanisms 9 and 14 is prevented, since this slipping immediately leads to a winder formation on the delivery mechanism. In that regard, during the application, the conveying means 37 and the conveying means 15 are activated in the processing stations. The guide and the manual application of the thread takes place by means of the thread suction gun 47, wherein the thread 11 is inserted successively in the processing point in the individual institutions. For - the case that the conveyor 37 is followed by a set heating device, the threading of the thread into the heating device can be simplified in particular by applying the thread suction gun directly to the output of the set heating device after transfer of the thread into the conveyor 37 will take over the thread again. The conveyor 37 is preferably coupled as an injector to the inlet of the heater.

The bobbin exchange is carried out in the embodiment shown in FIGS. 3 and 4 analogously to the exemplary embodiment according to FIGS. 1 and 2, so that a further description at this point can be omitted and reference is made to the above description.

FIGS. 5 and 6 show a further embodiment of the textile machine according to the invention. The embodiment of FIG. 5 is shown in a cross-sectional view and in Fig. 6 in a partial view of the machine longitudinal side. The structure of the textile machine is identical to the aforementioned embodiment of FIGS. 1 and 2, so that reference is made to avoid repetition of the above description. In the embodiments illustrated in FIGS. 5 and 6, the formation of the aids 22 are substantially different. Here, the thread suction 16 formed by a movable Stelleninjektor 38. The Stelleninjektor 38 is connected via a pipe 49 with a Garnabfallbehälter 28 and combined into a mobile control unit 40. The operating unit 40 is held by a carriage 46, which is designed to be movable in the lower region of the operating passage parallel to the machine longitudinal side 39.

As shown in FIG. 6, each group of superposed winding devices each has a parking position for the operating unit 40. In the parking position, in each case a pressure connection 30 is formed, to which the compressed air supply 26 of the operating unit 40 can be coupled. The compressed air supply 26 is coupled via a separate line to the location actuator 38 and to a thread suction gun 47. The yarn suction gun 47 has at the blowing end a discharge hose 48 which opens into the Garnabfallbehälter 28.

The conveying means provided for conveying the threads and for maintaining a thread tension on the outlet side of the stretch delivery devices are identical in their design and arrangement to the exemplary embodiments according to FIGS. 1 and 2, so that reference is likewise made to the aforementioned description.

In the partial view of the first three groups of winding devices 10.1 to 10.9 shown in FIG. 6, a bobbin change is currently being carried out in the middle group of the take-up devices 10.4 to 10.6. For this purpose, the operating unit 40 is held in the assigned parking position and connected to the pressure connection 30.2. To initiate the bobbin change the adjusting means 35.2 is opened, so that each of the connected conveyor 15.4 to 15.6 are connected to a pressure source, not shown here. The threads 11 assigned to the winding devices 10.4 to 10.6 are each conveyed separately by the conveying means 15.1 to 15.3, so that the operator can now initiate a change of bobbins by separating and transferring the threads to the position injector 38. The threads become the Garnabfallbehälter via the Stelleninjektor 38 28 led. The further procedure is essentially identical to the aforementioned exemplary embodiments. The re-application of the threads takes place with the aid of the thread suction gun 48, wherein each thread 11 is applied individually in the associated take-up 10.4 to 10.6.

In order to guide the thread in a simple manner in the delivery works downstream subsidies when first applying, an embodiment of a pneumatic conveyor is shown in Figs. 7 and 8, as it would be used for example the aforementioned embodiments of the textile machine according to the invention. FIG. 7 shows a view of the conveying means, and FIG. 8 shows a cross-sectional view. Unless express reference is made to any of the figures, the following description applies to both figures.

The conveyor 15 is al as a Fadeninjektor 45 is formed, which has an elongated guide channel 29 having an elongated Einlegschlitz 50 on one side. The guide channel 29 has a suction end 32 and a blowing end 33. In the region between the suction end 32 and the blowing end 33, several inflow channels 51 open, which can be connected via a pressure line 52 to a compressed air source.

To guide the thread within the guide channel 29, the conveyor 15 each at the suction end 32 and the blowing end 33 on a yarn guide 34. The yarn guide 34 can be formed for example by a ceramic insert.

To convey the yarn 11, compressed air in the yarn running direction is fed to the guide channel 29 via the pressure line 52 and the inflow channels 51. In this case, a suction effect is generated at the suction end 32 as well as at the blowing end 33. On the thread 11 creates a conveying action, which leads to the construction of a tensile stress. The exemplary embodiments of the textile machine according to the invention according to FIGS. 1 to 6 are exemplary in the construction and arrangement of their devices for treating, processing and winding up the threads. The construction of a false twist texturing machine according to FIG. 1 was selected, since the invention has proved particularly successful in such textile machines, since bottle twist texturing machines usually have a large number of processing stations and thus a large number of bobbin changes have to be carried out. Regardless of the design of the aids, the collectively controllable conveying means grouped into groups ensure a secure thread guidance even when using wrapping supplies that are particularly prone to curling. In this case, however, it is also possible to form the group division of the winding devices not in the form of a column but in the form of a tier or extend over a plurality of juxtaposed winding devices 2 x 1. Thus, the selected number of three rewinders and three collectively splittable conveyors is exemplary. Basically, a larger number of funding can be turned on collectively to prepare the bobbin change. This means that even parallel coil changes can be performed in several groups.
