Description

textile machine

The invention relates to a textile machine with a plurality of winding points for winding a plurality of threads according to the preamble of claim 1.

It is known that after a treatment and processing of threads they are wound up for storage in a coil. Thus, such textile machines have a plurality of Aufwickelstellen to wind in each of the winding one of the threads to one of the coil. For this purpose, the winding points are arranged one above the other in several levels and arranged side by side along a machine longitudinal side. In false twist texturing machines, as known for example from WO 03/091140, three take-up points are arranged one above the other, since the take-up points essentially have a width of three of the preceding processing points.

Such textile machines have auxiliary devices in order to perform a bobbin change in the Aufwi- ckelstellen when the wound coil has reached a predetermined size. The auxiliary devices can be formed depending on the operation of the Aufwickelstellen, so that automatic or manual bobbin change can be performed. Regardless of the design of the auxiliary equipment, the continuously fed yarns are received during the execution of the Spulwechsels and guided to a waste container.

In the textile machine known from WO 03/091140, a central waste container is used for this purpose, to which a main injector with its blow end is connected. The suction port of the main injector is used to at each of the winding points through a suction pipe, the threads if necessary to absorb and to pay. This system is preferably used for textile machine with automatic bobbin change, in order to ensure at each of the winding points at any time a discharge of the threads.

From US 2,206,834 a textile machine with a plurality of Aufwickelstellen is known in which the Aufwickelstellen auxiliary devices are associated with a plurality of Fadeninjektoren. The Fadeninjektoren are divided into groups and each associated with one of several waste containers. Depending on the plurality of Aufwickelstellen thus result in a variety of waste containers, each supplied independently, in particular must be emptied.

It is an object of the invention to develop a textile machine of the generic type such that an individual and efficient operability of each of the winding points is ensured, in particular when performing manual bobbin change.

Another object of the invention is to ensure the operation sequence for a bobbin change with the least possible operating effort on a textile machine with a variety of Aufwickelstellen.

This object is achieved by a textile machine with the features of claim 1.

Advantageous developments are defined by the features and feature combinations of the subclaims.

The invention is based on the principle that the pipelines used in the textile machine for discharging yarn waste are coupled on an inlet side and on an outlet side with stationary connections. In contrast, the invention admits that the vast majority of the bobbin change used auxiliary equipment are not functional due to missing connections. Since such auxiliary devices are used only in the case of a bobbin change within the Aufwickelstelle, the invention advantageously combines the structure of the device with the operating effort. Thus, the waste container is designed to be movable and has a container connection, which can be connected by a detachable coupling member alternately with the pipes of the thread suction. Thus, only the Aufwickelstelle on which a bobbin change must be performed, formed with functional auxiliary device. The invention thus offers the possibility of designing particularly cost-effective concepts for auxiliary devices for carrying out bobbin changes in the textile machine. Due to the direct connection of the waste container to the Aufwickelstellen, a safe removal of the thread waste is ensured by the thread suction. The bridging long distances is thereby avoided, so that correspondingly low discharge pressures are already sufficient to quickly and safely dissipate the thread waste during the Spulwechsels.

In a large number of Aufwickelstellen it is necessary that the waste container by simple means quickly and safely alternately connected to the bobbin change. For this purpose, the development of the invention has proven particularly useful in which the coupling member consists of a movable coupling carrier and a stationary clutch plate, which are quickly releasably connected to each other. Here, the coupling support for receiving the container connection is connected to the waste container and can be mobile from one coupling point to another lead. In contrast, the coupling plate is formed stationary and forms the connection of at least one of the pipes, wherein on the machine longitudinal side a plurality of coupling plates are arranged distributed to form in each case a coupling point. Thus, the activation of the auxiliary devices can be done quickly and safely at the winding stations located immediately before the Spulwechsel. For coupling the respective connections within the coupling carrier and coupling plate, conventional and known quick coupling systems can be used. In the event that a manual bobbin change is to be performed simultaneously at several adjacent Aurwickelstellen, the development of the textile machine according to the invention offers particular advantages in which the piping lines of several thread suction means are connected to a stationary coupling plate. The container connection of the waste container is formed on a coupling carrier, which is releasably connected to the coupling plate. This can be connected by a connection to the waste container at the same time a plurality of thread suction.

In a large number of thread-suction means, in particular the development of the invention has proved successful, in which the thread-suction means are divided into several suction groups, wherein the pipes fed to one of the suction groups are connected to one of a plurality of coupling plates and in which the coupling plates are distributed at a distance from one another the machine longitudinal sides are arranged. This allows a quick change to simultaneously connect multiple thread suction.

The winding stations arranged one above the other in a column are preferably supplied by a suction group. However, it is also possible to combine adjacent Aufwickelstellen one above the other and side by side to form a group.

The suction means for receiving and discharging the threads in the winding stations are formed according to a preferred embodiment of the invention by Stelleninjektoren, which is connected with a blowing end to one of the pipes. The suction of Stelleninjektors thereby forms the thread inlet, the direct air inlet of Stelleninjektors near the thread inlet leads to a safe and fast recording and Abiuhr the thread. When using point injectors, it is necessary that the compressed air supply to the point injector after activation of the waste container is activated. This can be done for example by a manual the Stelleninjektor associated control valve. A particularly advantageous embodiment is in contrast formed by the development of the textile machine according to the invention, in which in each case a pressure connection and at least one separate pressure line are formed on the coupling plate, wherein the pressure line is connected to the respective associated coupling plate Stelleniηjektoren. In contrast, the coupling carrier of the waste container, which cooperates with the coupling plate, contains a connection means by which the pressure line is connected to the pressure connection during coupling together. With this, the compressed air supply of the connected point injectors can be simultaneously activated when the waste container is connected.

In order to be able to create the threads one after the other in the winding stations after a bobbin change, the thread in the winding station is usually guided by means of a manual thread suction gun. In this case, the development of the textile machine according to the invention has proven particularly useful in which the mobile yarn suction gun for manual guidance of the threads is connected directly with a discharge hose to the waste container to a control unit.

The compressed air supply of the yarn suction gun can be advantageously realized via the coupling carrier, so that the pressure line of the yarn suction gun is connected to the coupling carrier.

The supplied from the clutch plate to the clutch carrier supply of compressed air can be done both by a separate compressed air connection exclusively to supply the thread suction gun or by a central compressed air connection in the coupling plate, through which both the thread gun and the Stelleninjektoren be supplied with compressed air. However, the thread suction means can also be advantageously formed by a suction tube, which opens into one of the pipes with one end. The auxiliary equipment for removing the yarn waste can thus be formed within the winding stations by simple pipe systems.

In order to allow a suction pressure generating negative pressure in the suction pipes, it is possible to additionally form a suction air connection to the coupling plate, which can be coupled via a separate container connection to the coupling carrier with the waste container. Thus, a vacuum can be generated in the waste container via the suction air connection, which propagates via the second separate container connection into the pipes and the suction pipes.

However, there is also the possibility that the waste container interacts directly with a waste injector, which can be activated via a pressure connection via the coupling member.

To further optimize the operation is proposed to arrange a guide rail along the machine longitudinal side on which a movable guide means is guided. The guide means includes means for holding the operating unit. In that regard, rapid replacement of the waste container can be performed without great force of an operator.

In this case, the waste container can preferably be formed by a rubbish bag, so that a simple handling is possible. In addition, the material of the rubbish bag could be matched to the thread material, so that the yarn waste could be disposed of together with the rubbish bag and recycled.

Further advantages of the textile machine according to the invention are explained in more detail below with reference to some embodiments with reference to the accompanying figures. They show:

Fig. 6 shows schematically a detail view of further exemplary embodiments of the textile machine according to the invention

In Fig. 1 and 2, a first embodiment of the textile machine according to the invention is shown. FIG. 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 operating passage 21. Immediately next to the machine frame 7, a gate frame 6 is arranged, which contains a plurality of original positions 1 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 winding points within the textile machine occupy a width of three processing points, so that in each case three Aufwickelstellen 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, the necessary for pulling off, guiding, treating and winding the thread 11 facilities are arranged on the machine frame 7 to a gangway 21 teilumschließenden yarn path.

Below, the facilities are briefly described by means of the yarn path in a processing station. To pull off the thread 11 in the processing station of a held in the gate frame 6 feed bobbin 2 a deduction delivery unit 3 is provided. 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 swirling device 13, a pre-set delivery mechanism 20, a set heating device 19, a set delivery mechanism 14 and one of the take-up points 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 points.

The winding stations 10.1 to 10.3, which are arranged one above the other from three adjacent processing stations, each comprise a bobbin holder 18, on which a bobbin 12 is held and wound, which is driven via a drive roller 17 during winding. The drive roller 17 is preceded by a traversing device, not shown here in the yarn path, which leads the thread before filing on the spool within a traverse stroke and forth, so that a cheese is wound in the take-up.

For further explanation of the Aufwickelstellen next to FIG. 1 reference is made at the same time to FIG. 2. FIG. 2 shows a view of the take-up point arranged along a machine longitudinal side 39, wherein only the first nine take-up points 10.1 to 10.9 are shown in FIG. The machine longitudinal side 39 extends parallel to the operation gear 21, from which an operator performs the Spulwechsel at the winding points 10.1 to 10.9. The Aufwickelstellen 10.1 to 10.9 are associated with several auxiliary devices 22.1 to 22.3, through which the implementation of the Spulwechsel is possible. The auxiliary devices 22.1 to 22.3 are each assigned to a group of Aufwickelstellen so that the auxiliary device 22.1 the Aufwickelstellen 10.1 to 10.3, the auxiliary device 22.2 the Aufwickelstellen 10.4 to 10.6 and the auxiliary device 22.3 the Aufwickelstellen 10.7 bi slθ.9 are assigned.

The auxiliary devices 22.1 to 22.3 are identical in their construction, so that only the construction of the auxiliary device 22.1 will be explained in more detail below. The auxiliary device 22.1 contains thread suction means 16 for receiving the threads during the implementation of a bobbin change. The thread suction means 16 are formed by a plurality of position injectors 23.1 to 23.3. The Stelleninjektoren 23.1 to 23.3 are each connected via separate pipes 24.1, 24.2 and 24.3 with a coupling plate 31. For this purpose, the coupling plate 31 is fastened in the lower region of the machine frame 7. For compressed air supply to the Stelleninjektoren 23.1 to 23.3 a pressure line 25 is connected to the coupling plate 31, which is connected via branches with the Stelleninjektoren 23.1 to 23.3. In addition to the connections of the pipes 24.1 to 24.3 and the connection of the pressure line 25, a compressed air connection 30 is formed in the coupling plate 31, which is coupled to a compressed air supply 26. The pressure port 30 within the clutch plate 31 is closed, so that the Stelleniηjektoren 23.1 to 23.2 are in a depressurized state, so that prevail at the mammal openings of Stelleninjektoren no suction.

As shown in Fig. 2, the auxiliary devices 22.1 and 22.2 out of service, so that at the winding points 10.1 to 10.6 no Spulwechsel are executable.

By contrast, the auxiliary device 22.3 is ready for carrying out a bobbin change in the winding stations 10.7 to 10.9. For this an operator input unit 40 consisting of a waste container 28 and a suction gun 15 via a coupling member 27 connected to the auxiliary device 23.3.

The coupling member 27 between the auxiliary device 22.3 and the operating unit 40 will be explained below with reference to FIGS. 3 and 4, wherein FIG. 3 is a cross-sectional view of the connection between the auxiliary device 22.3 and the control unit 40 and FIG. 4 is a partial section of the connection in the area of the pressure port 30 shows.

The operating unit 40 includes a waste container 28 with a container port 29 for receiving thread waste. The container connection 29 is in this case formed on a coupling carrier 32. The coupling carrier 32 can be connected to the coupling plate 31 in such a way that the connections of the pipes 24.7 to 24.9 open directly into the container connection 29, so that the threads 11 guided through the pipes 24.7 to 24.9 are led directly into the waste container 28. The container port 29 is detachably formed to remove the waste container 28 for emptying or change from the coupling support 32 can.

In the clutch carrier 32, a back pressure connection 34 is formed, which cooperates with the coupling connection plate 31 to the pressure connection 30 when coupling the coupling carrier 32.

In Fig. 4, the situation is shown shortly before the coupling of the coupling plate 31 with the coupling carrier 32. The pressure port 30 in the clutch plate 31 is blocked by a check valve 35. In the counter-pressure connection 34 of the coupling carrier 32, a plunger 36 is arranged, which protrudes with a free end into the pressure port 30 and when joining the coupling plate 31 with the coupling support 32 for opening the pressure connection 30 leads. When uncoupling the clutch carrier 32 from the clutch plate 31 thus the pressure port 30 is automatically closed by the check valve 35 when the ram 36 is pulled out.

As shown in Fig. 3, the back pressure port 34 leads directly into the pressure line 38 to supply a connected to the pressure line 38 thread suction gun 15 with compressed air. The yarn suction gun 15 is connected via a discharge hose 37 to the container port 29 of the waste container 28. Thus, the waste container 28 for receiving the Garnabfalle which are fed by the point leninjektoren 23.7 to 23.9 or via the thread suction gun 15 record (see also Fig. X).

As shown in Fig. 3, the coupling support 32 has a connection means formed as a connecting line 33 which connects the counter-pressure connection 34 in the coupled state with the terminal of the pressure line 25 in the coupling plate 31. Thus, at the same time the compressed air discharged from the pressure port 30 passes via the connecting line 32 into the pressure line 25, so that the Fadeninjektoren 23.7 to 23.9 are supplied with compressed air. Thus, only by coupling the operating unit 40, the auxiliary device 22.3 is switched onsfahig. The Spulwechselvorgang can be run in the Aufwickelstellen 10.7 to 10.9.

In this case, the winding process in the Aufwickelstellen 10.7 to 10.9 is manually interrupted and pass the severed threads in the mammalian openings of Stelleninjektoren 23.7 to 23.9. The coils can then be removed from the winding points 10.7 to 10.9 and replaced by empty tubes. To create the operator takes the threads 11 each individually by means of the thread suction gun 15 and leads them to the new sleeve, so that after catching a new winding process can begin. Once the Spulwechsel in the winding 10.7. is completed to 10.9, the coupling member 27 is released by separating the clutch plate 31 and the clutch carrier 32 and brought the control unit 40 to a next coupling point. The operating unit 40 may be designed to be mobile to be performed as a control car.

In the exemplary embodiment of the textile machine according to the invention shown in FIG. 1 and FIG. 2, the waste container 28 is formed by a rubbish bag. The waste bag is preferably formed of a material that can be recycled together with the yarn waste. At the control unit is filled with refuse container only a replacement of waste bags required, so that short very fast change are executable.

FIG. 5 schematically shows a further exemplary embodiment of the textile machine according to the invention in a cross-sectional view of the take-up points. The stacking points 10.1 to 10.3, which are arranged one above the other in the form of a tier, are schematically characterized by the illustration of a coil 12. Each take-up point 10.1 to 10.3 is in each case associated with a thread suction means 16, which in this case are formed by suction pipes 42. The suction pipes 42 are connected via a pipe line 24 to the stationary part of the coupling member 27. In addition to the pipe 24, a suction port 47 is disposed on the stationary part of the coupling member 27, which is connected to a blower 41.

To accommodate the Garnabfälle, the waste container 28 two Behälteran- conclusions 29.1 and 29.2, which are formed on the mobile part of the coupling member 27. In the coupled state of the coupling member 27 of the container port 29.1 corresponds to the suction port 47 and the container port 29.2 with the connection of the pipe 24. Thus, a negative pressure is generated within the waste container 28, which leads to a suction effect in the pipe 24 and the intake pipes 42 enclosed therein , In this condition, the tapered threads are continuously guided at the Aufwickelstellen 10.1 to 10.3 in the waste container 28.

In order to be able to move the waste container 28 on the longitudinal machine side to adjacent Aufwi- ckelstellen, the waste container 28 is held by a guide carriage 44 on a guide rail 43. As a result, by moving the guide carriage 44 on the guide rail 43, an operator can perform a quick change of the take-up point.

FIG. 6 shows a further embodiment of the textile machine according to the invention, wherein the reel-up points 10.1 to 10.3 arranged one above the other in the form of a tier are symbolically characterized by the representation of a reel. Each of the winding points 10.1 to 10.3 is associated with a suction tube 42 as a thread suction. The suction pipes 42 are connected via the pipe 24 to the stationary part of the coupling member 27. Separate from the pipe connection, the coupling member 27 has a pressure port 30 which is connected to a pressure source, not shown here.

To generate a suction flow, a waste injector 45 is arranged on the waste container 28. The waste injector 45 is connected via a container port 29 and a counter-pressure port 34 to the coupling member 27.

In the coupled state of the waste injector 45 is supplied via the pressure port 30 and the back pressure port 34 with compressed air. The suction flow generated on the suction side of the waste injector 45 is guided via the existing at the free end of the suction tubes 42 mammalian openings via the pipe 24 and the container port 29.

In addition to the waste injector 45, a yarn suction gun 15 is connected to the pressure port 30 via the pressure line 38. The blowing end of the yarn suction gun 15 opens via the discharge hose 37 directly into the waste container 28, so that a complete control unit 40 is given to the bobbin change and new creation of the threads in the winding points 10.1 to 10.3. The operating unit 40 is held and guided in this exemplary embodiment by a carriage 46. For this purpose, the waste container 28 is arranged directly on the carriage 46. The waste container 28 may be both rigid and flexible, for example, formed as a rubbish bag. Depending on the design of the waste container 28 may be releasably connected to the carriage 46. However, it is also possible that the waste container 28 remains on the carriage 46 and can be opened for emptying.

The embodiments of the textile machine according to the invention are exemplary in the construction and arrangement of their facilities for treating, processing and winding the threads. The structure of a false twist texturing machine according to FIG. 1 was selected because the invention has proven particularly useful in such textile machines, since false twist texturing machines usually have a high number of processing stations and thus long guiding distances of the operating unit are given.

Regardless of the design of the textile machine, the invention has the particular advantage that all power to the control unit is provided in each case at the coupling point. A permanent supply of energy to the control unit, for example by energy chains is not required. This ensures the high flexibility required for manual operations for the removal of yarn waste during a bobbin change and a thread handling during the new creation.

In the exemplary embodiments of the textile machine according to the invention shown in FIGS. 2, 5 and 6, the auxiliary devices have a thread suction means per winding position. However, the invention also extends to such variants of textile machines in which a plurality of juxtaposed and / or superposed winding stations are associated with a thread suction means. Thus, several threads can be discharged simultaneously through a thread suction. In addition, the operating unit with the waste container can also advantageously be guided above the floor in an area above the winding on the textile machine. The change between the individual docking positions in the textile machine is preferably carried out manually. But also automated processes are possible.
