Definitions
- the present invention relates to a textile machine assembly comprising a delivery unit, in particular a carding machine, by means of which a sliver is supplied during operation of the delivery unit, a receiving unit, in particular a route, by means of which the sliver supplied by the delivery unit is received during operation of the receiving unit.
- the textile machine assembly comprises at least one tape storage unit, which at a delivery speed of the sliver to the delivery unit, which is higher than a receiving speed of the sliver at the receiving unit, the excess sliver between the delivery unit and the receiving unit at least temporarily stores, and at a receiving speed of the sliver at the receiving unit, which is higher than the delivery speed of the sliver on the delivery unit, the canned sliver releases.
- the invention relates to textile machines for delivering and receiving sliver, each textile machine having a band storage unit for buffering the sliver.
- the invention relates to a method for operating the textile machine composite.
- a device for transporting a sliver comprises an associated input section, output section and guide section for each fiber sliver to be transported.
- the guide section has an associated drive section which is adapted to grip the sliver to be transported at at least one location. It is further configured to receive the sliver coming from the input section in the direction of the output section with a length which is greater than a distance between the drive section and the output section.
- the disadvantage here is that the sliver are absorbed only by a loop formation can, which can lead to knotting and damage of the sliver, especially with large loops, for example.
- Object of the present invention is therefore to eliminate the disadvantage of the prior art.
- the object is achieved by a textile machine network, textile machines and a method for temporary storage of a sliver on a textile machine and / or a textile machine network with the features of the independent claims.
- a textile machine assembly with a delivery unit by means of which a sliver is supplied during operation of the delivery unit, is proposed.
- the delivery unit can be, for example, a card which produces or provides a sliver.
- the delivery unit can also be another unit of the textile machine network, which processes a sliver, prepares it for a subsequent work step and / or merely forwards it.
- the textile machine network further has a receiving unit, by means of which the sliver supplied by the delivery unit is received during operation of the receiving unit.
- the receiving unit is thus downstream of the delivery unit.
- the receiving unit can be a line which stretches the fiber sliver supplied by the delivery unit and thereby further processes it.
- the receiving unit may also be any unit of the textile machine network, which receives a sliver for further processing or merely forwards.
- the sliver In normal operation of the textile machine composite, the sliver can be continuously supplied from the delivery unit and received continuously by the receiving unit.
- the textile machine assembly has at least one band storage unit, by means of which the sliver can be temporarily stored at least temporarily.
- the tape storage unit stores, for example, the sliver when a delivery speed of the sliver on the delivery unit is higher than a receiving speed of the sliver at the receiving unit.
- the delivery unit thus delivers the sliver faster than it can receive, record, process and / or forward the receiving unit. Due to the fact that the sliver can be buffered, for example, the delivery speed of the delivery unit does not have to be adapted or only slightly adapted. For example, the delivery unit need not be stopped to allow the receiving unit time to receive the excess sliver.
- the band storage unit can also release the buffered sliver if the receiving speed of the sliver at the receiving unit is higher than the delivery speed of the sliver on the delivery unit.
- the receiving unit forwards the fiber sliver more quickly and / or further processed than it can deliver or provide the delivery unit.
- it can be emptied again by the tape storage unit in which the sliver is stored.
- the tape storage unit can thus also be used as an intermediate buffer for sliver.
- the band storage unit has at least one deflection unit which can be moved relative to the delivery unit and which can deflect the sliver.
- the deflection unit may additionally or alternatively also be movable relative to the reception unit. With the help of the deflection unit, the sliver can be deflected.
- a sliver path for the sliver can be changed from the delivery unit to the receiving unit.
- the sliver path can be the path that the sliver has to travel from the delivery unit to the receiving unit when the sliver is maximally tightened.
- the Faserbandweg for example, a shortest, so be a direct, path between an exit point of the sliver at the delivery unit and an entry point of the sliver at the receiving unit (this is a possible slack of the sliver initially not be considered, which of course also contributes to Faserbandweg).
- a shortest path can be for example 2 m.
- the deflection unit can, for example, be moved in such a way that the sliver path extends from the delivery unit to the reception unit.
- the deflection unit can, for example, be moved in such a way that the sliver has to make a detour from the delivery unit to the reception unit.
- the sliver therefore has to travel a longer distance from the delivery unit in order to reach the receiving unit.
- a longer sliver section is arranged between the delivery unit and the receiving unit.
- the sliver path can be lengthened, for example, from the above-described 2 m to, for example, 3 m, so that 1 m sliver can be temporarily stored.
- the sliver path can be shortened again.
- the deflection can be moved in the opposite direction, for example, in contrast to extending the Faserbandweges.
- an additional sliver section can be released.
- At least one strip storage unit is arranged on the delivery unit. Additionally or alternatively, at least one band storage unit can also be arranged on the receiving unit. Also in addition or alternatively, a Band storage unit may be arranged in a region between the delivery unit and the receiving unit. This allows the Faserbandweg be adjusted specifically.
- the deflection unit is movable in a first direction along the direction of gravity. Gravity causes the sliver to sag and form a loop as the delivery unit delivers sliver faster than the receiving unit can receive. If the loop is large enough, the sliver is on a substrate between the delivery unit and the receiving unit, whereby the sliver is dirty or damaged and can knot.
- the deflection unit can, for example, against gravity, ie upwards away from the ground, are moved, so that the sliver is deflected away from the ground. A ground contact of the sliver can be prevented. In addition, with a movement of the deflection up particularly much sliver can be cached.
- the deflecting unit is movable in a second direction perpendicular to the direction of gravity and parallel along a connecting axis between the delivery unit and the receiving unit.
- the deflection unit can thereby be moved back and forth, for example, between the delivery unit.
- sliver can be cached, if not much space is available in the environment of the textile machine network.
- the textile machine composite can be designed to save space.
- the deflection unit is movable in a third direction perpendicular to the direction of gravity and perpendicular to the connection axis.
- the deflection unit can thus be moved transversely between the delivery unit and the reception unit. As a result, the sliver can be deflected laterally.
- the deflection unit is movable such that the first, the second and / or the third direction are superimposed. This allows the deflection can be moved anywhere in the room. If, for example, further movement of the deflection unit in the first direction, for example upwards, is no longer possible, the deflection unit can be moved, for example, in the third direction. This increases flexibility in the movement of the deflection unit.
- the deflecting unit is movable by a distance which corresponds to at least 50% of the distance between the delivery unit and the receiving unit.
- the distance by which the deflection unit is movable may also correspond to at least 100% of the distance between the delivery unit and the reception unit.
- the at least one band storage unit has an actuator, by means of which the deflection unit is movable. As a result, the deflection can be moved automatically.
- the actuator comprises a hydraulic actuator, a pneumatic actuator, an electric motor, a stepper motor and / or a servomotor.
- the deflection unit is arranged on an extension which is movable by means of the actuator.
- the extension may also be pivotable, so that the deflection unit can be pivoted.
- the extension may also be a telescopic rod, so that the tape storage unit can be made compact, but the deflection unit is still movable by a long way.
- the deflection unit comprises a roller.
- About the role of the sliver can run. This allows the sliver to be well diverted.
- the roller may also be driven by means of a drive, so that the roller actively passes the sliver.
- the textile machine network comprises a controller, which is connected to the data exchange with the delivery unit. Additionally or alternatively, the controller may also be connected to the receiving unit for data exchange. For example, the controller may receive the delivery speed of the delivery unit and / or the receiving speed of the receiving unit. Additionally or alternatively, the controller may receive a time of imminent can change. For example, in connection with a can change on the receiving unit designed as a route, the controller can determine how the deflection unit has to be moved in order to buffer sliver in order to compensate for a decrease in the receiving speed. The controller can also throttle or stop the reception speed.
- a textile machine which may be for example a card.
- the textile machine comprises a delivery unit, by means of which a sliver is supplied during operation of the delivery unit.
- the textile machine comprises at least one belt storage unit, which at a delivery speed of the sliver to the delivery unit, which is higher than a receiving speed of the sliver at a receiving unit of another textile machine, the excess sliver between the delivery unit and the receiving unit at least temporarily stores.
- the sliver can be released from the tape storage unit.
- the band storage unit has at least one deflection unit movable relative to the delivery unit, with the aid of which the sliver can be deflected and by means of which a sliver path for the sliver can be changed from the delivery unit to the receiving unit.
- the band storage unit may preferably have one or more features according to the preceding and / or following description.
- the textile machine comprising the delivery unit and the further textile machine comprising the receiving unit can form the textile machine assembly described above.
- a textile machine which may for example be a route.
- the textile machine comprises a receiving unit, by means of which a sliver is received during operation of the receiving unit.
- the textile machine comprises at least one tape storage unit, which at a receiving speed of the sliver at the receiving unit, which is lower than a delivery speed of the sliver at a delivery unit of another textile machine, the excess sliver between the supply unit and the receiving unit at least temporarily stores.
- the further textile machine may for example be a card.
- the tape storage unit may also release the cached sliver at a receiving speed of the sliver at the receiving unit that is higher than the delivery speed of the sliver at the delivery unit.
- the band storage unit has at least one deflecting unit which is movable relative to the receiving unit and with the aid of which the sliver can be deflected and by means of which a sliver path for the sliver can be changed from the delivery unit to the receiving unit.
- the band storage unit may preferably have one or more features according to the preceding and / or following description.
- the textile machine comprising the receiving unit and the further textile machine comprising the delivery unit can form the textile machine assembly described above.
- the textile machine composite can be designed according to at least one feature of the preceding and / or following description.
- the textile machine assembly comprises a delivery unit, by means of which a sliver is supplied during operation of the delivery unit.
- the delivery unit can be for example a card which delivers a sliver.
- the delivery unit can also be another unit of the textile machine network. The delivery unit provides the sliver.
- the textile machine network comprises a receiving unit, by means of which the sliver supplied by the delivery unit is received during operation of the receiving unit.
- the receiving unit may be, for example, a route.
- the receiving unit can also be another unit of the textile machine network.
- the receiving unit receives the sliver, for example, to forward and / or process it.
- the textile machine assembly comprises a tape storage unit, which at a delivery speed of the sliver on the delivery unit, which is higher than a receiving speed of the sliver at the receiving unit, the excess sliver between the supply unit and the receiving unit, at least temporarily stores.
- the band storage unit may release the buffered sliver at a receiving speed of the sliver at the receiving unit that is higher than the delivery speed of the sliver at the delivery unit.
- the band storage unit has at least one deflection unit which is movable relative to the delivery unit and with the aid of which the sliver is deflected at least temporarily.
- the deflecting unit can additionally or alternatively also be moved relative to the receiving unit.
- the sliver path may be the path that the sliver must travel from the delivery unit to the receiving unit.
- the sliver path can, for example, be the shortest path, that is to say the direct route, from the delivery unit to the receiving unit.
- this sliver path is lengthened, for example, if sliver is to be temporarily stored.
- the sliver must thereby cover a detour from the delivery unit to the receiving unit.
- a larger sliver piece is arranged between the delivery unit and the receiving unit, so that the excess sliver is temporarily stored.
- the direct distance from the delivery unit to the receiving unit is 2 m.
- the deflection unit is now moved, so that the Faserbandweg is extended.
- the sliver for example, now has to cover a distance from the delivery unit to the receiving unit, which is 3 m. The difference of 1 m sliver is buffered.
- the sliver path is again 2 m.
- the additional 1 m will be released again.
- the excess 1 m sliver can be picked up by the receiving unit when it receives the sliver faster than the delivery unit delivers.
- the deflecting unit is moved in a slack sliver, so that the Faserbandweg is increased.
- the deflection can be moved, for example, against the slack sliver up.
- the sliver is advantageously lifted from a substrate, so that it does not deposit on this.
- the deflection unit is moved in such a way that a loop formed by the slack sliver is reduced. As a result, it is guided away from the ground, so that the larger distance between the sliver and the ground can be available again for buffering the sliver. Additionally or alternatively, the deflection unit can also be moved in such a way that the loop remains constant in size.
- the deflection unit is moved in such a way that the sliver path is shortened.
- the diverting unit may be moved counter to the direction in which the diverting unit has been moved in order to increase the fiber band path.
- the deflection unit can be moved back to a starting position.
- FIG. 1 shows a textile machine assembly 1 with a delivery unit 3 and a receiving unit. 4
- a sliver 2 is supplied during operation of the textile machine assembly 1.
- the delivery unit 3 can be, for example, a card which can card textile fibers.
- the delivery unit 3 may also be another unit that provides the sliver 2.
- the delivery unit 3 can deliver the sliver 2 at a delivery speed during operation.
- the delivery speed can be for example 10 m / min. Thus, 10 m of sliver are delivered per minute from the delivery unit 3.
- the receiving unit 4 By means of the receiving unit 4, the sliver 2 supplied by the delivery unit 3 is received during operation of the textile machine assembly 1.
- the receiving unit 4 is a track which has a drafting device 5.
- the receiving unit 4 can also be another unit that receives the sliver 2.
- the receiving unit 4 can according to the present embodiment, an input role 6, by means of which the sliver 2 can be introduced into the receiving unit 4.
- the receiving unit 4 may have a receiving speed with which the receiving unit 4 receives the sliver 2.
- the delivery speed of the delivery unit 3 and the receiving speed of the receiving unit 4 are the same. This prevents on the one hand that the sliver 2 tears off. On the other hand, it is prevented that the sliver 2 is deposited on a substrate 12 between the delivery unit 3 and the receiving unit 4, whereby the sliver 2 can be dirty and damaged.
- the sliver 2 may have a first sliver path 7.
- the first sliver path 7 may be a direct path between an exit point 10 of the sliver 2 on the delivery unit 3 and an entry point 11 of the sliver 2 on the receiving unit 4.
- the sliver 2 on the first Faserbandweg 7. This can represent normal operation of the textile machine assembly 1.
- the receiving unit 4 is, for example, a section 4, it may be arranged downstream of a pot, not shown here, in which the sliver 2 stretched by the section 4 is deposited. After a while, the pot will be completely filled and a can change is necessary. For this purpose, the receiving unit 4 must be stopped for a short time or at least briefly braked in a processing speed. That is, the receiving unit 4, the sliver 2 only slower to receive or, if it is stopped, not received. The receiving speed of the receiving unit 4 is lower compared to the receiving speed in normal operation. However, if the delivery unit 3 delivers the sliver 2 at an unchanged delivery speed and thus the delivery speed is higher than the receiving speed, it forms according to FIG FIG.
- a sliver loop 9 which is shown in dashed lines. Will the Sliver loop 9 larger than in FIG. 1 shown, the sliver 2 will eventually settle on the substrate 12, which may be disadvantageous as described above.
- the textile machine assembly 1 may comprise a belt storage unit 13 which comprises a deflection unit 14.
- the sliver 2 can be deflected.
- the sliver path for the sliver 2 from the delivery unit 3 to the receiving unit 4 can also be changed.
- the band storage unit 13 with the deflection unit 14 is arranged on the receiving unit 4 in this exemplary embodiment. Additionally or alternatively, the band storage unit 13 may also be arranged on the delivery unit 3. Additionally or alternatively, a band storage unit 13 may also be arranged in the region between the delivery unit 3 and the receiving unit 4. For example, the tape storage unit 13 may stand on the ground 12.
- the tape storage unit 13 has an extension 15, at the end of the deflection unit 14 is arranged.
- the tape storage unit 13 may include an actuator, not shown here, by means of which the extension 15 is movable, so that the deflection unit 14 can be moved.
- the actuator may be, for example, a hydraulic actuator, a pneumatic actuator, an electric motor and / or a stepper motor, wherein the actuator is controllable by a controller 17 in order to move the deflection unit 14.
- the extension 15 may for example be a telescopic rod, so that the deflection unit 14 can be moved even further.
- the textile machine assembly 1 may further comprise the controller 17, which can move the deflection unit 14.
- the controller 17 may receive, for example, information from the delivery unit 3 and / or the receiving unit 4.
- the controller 17 may receive the delivery speed of the sliver 2 on the delivery unit 3.
- the controller 17 may also be the receiving speed of the sliver 2 at the Receiving unit 4 received.
- the controller 17 may calculate the difference therefrom. From this, the controller 17 can calculate how much sliver 2 is to be buffered.
- the controller 17 can move the deflection unit 14 accordingly.
- FIG. 3 shows a textile machine assembly 1 with the delivery unit 3, the receiving unit 4 and with moving deflection unit 14.
- the deflection unit 14 is moved along a first direction Z.
- the first direction Z is oriented parallel to a direction of gravity S. Gravity along the direction of gravity S pulls the sliver 2 down into the loop 9 in the direction of the ground 12.
- the deflection unit 14 is further moved counter to the direction of gravity S along the first direction Z.
- the first Faserbandweg 7 according to the FIG. 1 or 2 is now marked by a dashed line.
- the first Faserbandweg 7 is for example 2 m. Since the deflecting unit 14 is moved, the sliver path has also changed.
- the sliver 2 now has to cover a second sliver path 8 in order to reach the receiving unit 4.
- the second Faserbandweg 8 is opposite to the first Faserbandweg 7 a detour, so that the second Faserbandweg 8 is longer than the first Faserbandweg 7.
- the sliver 2 must now run from the exit point 10 and the deflection unit 14 to get to the entry point 11.
- the second Faserbandweg 8 has, for example, a length which is 2.5 m.
- a difference between the second and the first Faserbandweg 7, 8 is 0.5 m, so that this length of fiber sliver 2 is cached.
- the deflection unit 14 can be moved, for example, at a time in the first direction Z against the direction of gravity S when the reception speed at the receiving unit 4 falls below the delivery speed at the delivery unit 3.
- the sliver 2 is thus simultaneously pulled up when more sliver 2 is supplied by the delivery unit 3 than can be received by the receiving unit 4. This case occurs For example, when the receiving unit 4 is a distance and a can change is started.
- the deflection unit 14 can also only move in the first direction Z against the direction of gravity S when the loop 9 has formed. Only when, for example, the loop 9 according to the embodiment of FIG. 2 has formed, the deflection unit 14 can be moved in the first direction Z against gravity and thus away from the substrate 12. According to FIG. 3 the sliver 2 then has a third sliver path 16. By means of the loop 9, in contrast to the second Faserbandweg 8 more sliver 2 is cached.
- the third sliver path 16, which leads from the exit point 10 through the loop 9 and via the deflection unit 14 to the entry point 11, may for example have a length of 3.5 m.
- the first Faserbandweg 7 is 2 m, so that in contrast to 1.5 m sliver 2 are cached.
- 1.5 m sliver 2 can be cached, if at the beginning of the sliver 2 along the first Faserbandweges 7 was arranged.
- the delivery speed is, for example, 10 m / min and the receiving unit 4 is completely stopped, for example for a can change, it takes 9 seconds until 1.5 m sliver 2 are buffered. That is, the can change may take 9 seconds until the receiving unit 4 must be restarted to receive the sliver 2 again.
- the deflection unit 14 can be moved back to the starting position.
- the deflection unit 14 is moved in the first direction Z in the direction of the ground 12.
- the release can be done, for example, when the can change is completed.
- the receiving unit 4 can receive the sliver 2 faster for a short period of time than the delivery unit 3 delivers. As a result, the excess sliver 2 is introduced into the receiving unit 4.
- the deflection unit 14 only in the Starting position to be moved back when the loop 9 has receded.
- the sliver 2 then no longer runs along the third sliver path 16 but along the second sliver path 8. Only then can the deflecting unit 14 be moved.
- the deflecting unit 14 can also be moved in such a way that at the same time the loop 9 forms back and the deflecting unit 14 is moved.
- FIG. 4 shows a schematic view of a textile machine assembly 1 with a delivery unit 3, a receiving unit and a moving deflection unit 14.
- the deflection unit 14 is movable in this embodiment in addition to the first direction Z in a second direction X.
- the second direction X is oriented along a connection axis between delivery unit 3 and receiving unit 4.
- the deflecting unit 14 can thus be moved in the direction of the delivery unit 3 and / or in the direction of the receiving unit 4 by means of the second direction X.
- the movement of the deflection unit 14 is superimposed in the first direction Z and in the second direction X.
- the deflection unit 14 can thus also be moved obliquely.
- the deflection unit 14 can still be moved along a third direction Y, which is not shown here.
- the third direction Y is oriented out of the plane of the drawing or into it. The deflection unit 14 can thus be moved laterally along the third direction Y.

Aus der
Aufgabe der vorliegenden Erfindung ist es somit, den Nachteil des Stands der Technik zu beseitigen.Object of the present invention is therefore to eliminate the disadvantage of the prior art.
Die Aufgabe wird gelöst durch einen Textilmaschinenverbund, Textilmaschinen sowie ein Verfahren zum Zwischenspeichern eines Faserbandes an einer Textilmaschine und/oder einem Textilmaschinenverbund mit den Merkmalen der unabhängigen Patentansprüche.The object is achieved by a textile machine network, textile machines and a method for temporary storage of a sliver on a textile machine and / or a textile machine network with the features of the independent claims.
Vorgeschlagen wird ein Textilmaschinenverbund mit einer Liefereinheit, mittels der ein Faserband beim Betrieb der Liefereinheit geliefert wird. Die Liefereinheit kann beispielsweise eine Karde sein, die ein Faserband herstellt oder bereitstellt. Die Liefereinheit kann aber auch eine andere Einheit des Textilmaschinenverbunds sein, die ein Faserband verarbeitet, für einen nachfolgenden Arbeitsschritt bereitstellt und/oder lediglich weiterleitet.A textile machine assembly with a delivery unit, by means of which a sliver is supplied during operation of the delivery unit, is proposed. The delivery unit can be, for example, a card which produces or provides a sliver. However, the delivery unit can also be another unit of the textile machine network, which processes a sliver, prepares it for a subsequent work step and / or merely forwards it.
Der Textilmaschinenverbund weist ferner eine Empfangseinheit auf, mittels der das von der Liefereinheit gelieferte Faserband beim Betrieb der Empfangseinheit empfangen wird. Die Empfangseinheit ist somit der Liefereinheit nachgeordnet. Die Empfangseinheit kann beispielsweise eine Strecke sein, die das von der Liefereinheit gelieferte Faserband verstreckt und dadurch weiterverarbeitet. Die Empfangseinheit kann aber auch jede Einheit des Textilmaschinenverbunds sein, die ein Faserband zur Weiterverarbeitung erhält oder lediglich weiterleitet.The textile machine network further has a receiving unit, by means of which the sliver supplied by the delivery unit is received during operation of the receiving unit. The receiving unit is thus downstream of the delivery unit. By way of example, the receiving unit can be a line which stretches the fiber sliver supplied by the delivery unit and thereby further processes it. However, the receiving unit may also be any unit of the textile machine network, which receives a sliver for further processing or merely forwards.
Im normalen Betrieb des Textilmaschinenverbunds kann das Faserband kontinuierlich von der Liefereinheit geliefert und von der Empfangseinheit kontinuierlich empfangen werden.In normal operation of the textile machine composite, the sliver can be continuously supplied from the delivery unit and received continuously by the receiving unit.
Außerdem weist der Textilmaschinenverbund zumindest eine Bandspeichereinheit auf, mittels der das Faserband zumindest zeitweise zwischengespeichert werden kann. Die Bandspeichereinheit speichert beispielsweise das Faserband, wenn eine Liefergeschwindigkeit des Faserbandes an der Liefereinheit höher ist als eine Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit. Die Liefereinheit liefert somit das Faserband schneller als es die Empfangseinheit empfangen, aufnehmen, weiterverarbeiten und/oder weiterleiten kann. Dadurch, dass das Faserband zwischengespeichert werden kann, muss beispielsweise die Liefergeschwindigkeit der Liefereinheit nicht oder nur wenig angepasst werden. Die Liefereinheit muss beispielsweise nicht gestoppt werden, um der Empfangseinheit Zeit zu geben, das überschüssige Faserband zu empfangen.In addition, the textile machine assembly has at least one band storage unit, by means of which the sliver can be temporarily stored at least temporarily. The tape storage unit stores, for example, the sliver when a delivery speed of the sliver on the delivery unit is higher than a receiving speed of the sliver at the receiving unit. The delivery unit thus delivers the sliver faster than it can receive, record, process and / or forward the receiving unit. Due to the fact that the sliver can be buffered, for example, the delivery speed of the delivery unit does not have to be adapted or only slightly adapted. For example, the delivery unit need not be stopped to allow the receiving unit time to receive the excess sliver.
Ebenso kann die Bandspeichereinheit das zwischengespeicherte Faserband auch wieder freigeben, wenn die Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit höher ist als die Liefergeschwindigkeit des Faserbandes an der Liefereinheit. Dadurch kann der Fall ausgeglichen werden, in dem die Empfangseinheit das Faserband schneller weiterleitet und/oder weiterverarbeitet als es die Liefereinheit liefern bzw. bereitstellen kann. Ferner kann dadurch die Bandspeichereinheit, in der das Faserband zwischengespeichert ist, wieder geleert werden. Die Bandspeichereinheit kann somit auch als Zwischenpuffer für Faserband verwendet werden.Likewise, the band storage unit can also release the buffered sliver if the receiving speed of the sliver at the receiving unit is higher than the delivery speed of the sliver on the delivery unit. Thereby, the case can be compensated, in which the receiving unit forwards the fiber sliver more quickly and / or further processed than it can deliver or provide the delivery unit. Furthermore, it can be emptied again by the tape storage unit in which the sliver is stored. The tape storage unit can thus also be used as an intermediate buffer for sliver.
Erfindungsgemäß weist die Bandspeichereinheit zumindest eine gegenüber der Liefereinheit bewegbare Umlenkeinheit auf, die das Faserband umlenken kann. Die Umlenkeinheit kann zusätzlich oder alternativ auch gegenüber der Empfangseinheit bewegbar sein. Mit Hilfe der Umlenkeinheit kann das Faserband umgelenkt werden. Mittels der Umlenkeinheit kann ein Faserbandweg für das Faserband von der Liefereinheit zur Empfangseinheit verändert werden. Der Faserbandweg kann dabei der Weg sein, den das Faserband von der Liefereinheit zur Empfangseinheit zurücklegen muss, wenn das Faserband maximal gestrafft ist. Der Faserbandweg kann beispielsweise ein kürzester, also eine direkter, Weg zwischen einem Austrittspunkt des Faserbandes an der Liefereinheit und einem Eintrittspunkt des Faserbandes an der Empfangseinheit sein (hier soll ein mögliches Durchhängen des Faserbandes zunächst nicht beachtet werden, das natürlich ebenfalls zum Faserbandweg beiträgt). Ein derartiger kürzester Weg kann beispielsweise 2 m betragen.According to the invention, the band storage unit has at least one deflection unit which can be moved relative to the delivery unit and which can deflect the sliver. The deflection unit may additionally or alternatively also be movable relative to the reception unit. With the help of the deflection unit, the sliver can be deflected. By means of the deflecting unit, a sliver path for the sliver can be changed from the delivery unit to the receiving unit. The sliver path can be the path that the sliver has to travel from the delivery unit to the receiving unit when the sliver is maximally tightened. The Faserbandweg, for example, a shortest, so be a direct, path between an exit point of the sliver at the delivery unit and an entry point of the sliver at the receiving unit (this is a possible slack of the sliver initially not be considered, which of course also contributes to Faserbandweg). Such a shortest path can be for example 2 m.
Die Umlenkeinheit kann beispielsweise derart bewegt werden, dass sich der Faserbandweg von der Liefereinheit zur Empfangseinheit verlängert. Die Umlenkeinheit kann beispielsweise derart bewegt werden, dass das Faserband von der Liefereinheit zur Empfangseinheit einen Umweg zurücklegen muss. Das Faserband muss somit von der Liefereinheit eine längere Strecke zurücklegen, um zur Empfangseinheit zu gelangen. Dadurch ist zwischen der Liefereinheit und der Empfangseinheit ein längerer Faserbandabschnitt angeordnet. Der Faserbandweg kann beispielsweise von den oben beispielhaft beschriebenen 2 m auf beispielsweise 3 m verlängert werden, so dass 1 m Faserband zwischengespeichert werden kann.The deflection unit can, for example, be moved in such a way that the sliver path extends from the delivery unit to the reception unit. The deflection unit can, for example, be moved in such a way that the sliver has to make a detour from the delivery unit to the reception unit. The sliver therefore has to travel a longer distance from the delivery unit in order to reach the receiving unit. As a result, a longer sliver section is arranged between the delivery unit and the receiving unit. The sliver path can be lengthened, for example, from the above-described 2 m to, for example, 3 m, so that 1 m sliver can be temporarily stored.
Um das überschüssige Faserband zwischen der Liefereinheit und der Empfangseinheit wieder freigeben zu können, kann der Faserbandweg wieder verkürzt werden. Dazu kann die Umlenkeinheit beispielsweise im Gegensatz zum Verlängern des Faserbandweges in die entgegengesetzte Richtung bewegt werden. Dadurch kann ein zusätzlicher Faserbandabschnitt freigegeben werden. Durch die Empfangseinheit, die das Faserband schneller empfangen kann als es die Liefereinheit liefern kann, kann das überschüssige Faserband aufgenommen werden. Dadurch wird der Geschwindigkeitsunterschied zwischen der Empfangseinheit und der Liefereinheit ausgeglichen.In order to release the excess sliver between the delivery unit and the receiving unit, the sliver path can be shortened again. For this purpose, the deflection can be moved in the opposite direction, for example, in contrast to extending the Faserbandweges. As a result, an additional sliver section can be released. By the receiving unit, which can receive the sliver faster than it can deliver the delivery unit, the excess sliver can be recorded. This compensates for the difference in speed between the receiving unit and the delivery unit.
In einer vorteilhaften Weiterbildung der Erfindung ist zumindest eine Bandspeichereinheit an der Liefereinheit angeordnet. Zusätzlich oder alternativ kann auch zumindest eine Bandspeichereinheit an der Empfangseinheit angeordnet sein. Ebenfalls zusätzlich oder alternativ kann auch eine Bandspeichereinheit in einem Bereich zwischen der Liefereinheit und der Empfangseinheit angeordnet sein. Dadurch kann der Faserbandweg gezielt verstellt werden.In an advantageous development of the invention, at least one strip storage unit is arranged on the delivery unit. Additionally or alternatively, at least one band storage unit can also be arranged on the receiving unit. Also in addition or alternatively, a Band storage unit may be arranged in a region between the delivery unit and the receiving unit. This allows the Faserbandweg be adjusted specifically.
Von Vorteil ist es, wenn die Umlenkeinheit in einer ersten Richtung entlang der Schwerkraftrichtung bewegbar ist. Die Schwerkraft bewirkt, dass das Faserband durchhängt und eine Schlaufe bildet, wenn die Liefereinheit schneller Faserband liefert als es die Empfangseinheit empfangen kann. Wenn die Schlaufe groß genug ist, liegt das Faserband auf einem Untergrund zwischen der Liefereinheit und der Empfangseinheit auf, wobei das Faserband verschmutzen oder beschädigt wird und sich verknoten kann. Die Umlenkeinheit kann beispielsweise entgegen der Schwerkraft, also nach oben vom Untergrund weg, bewegt werden, so dass das Faserband vom Untergrund weg umgelenkt wird. Eine Bodenberührung des Faserbandes kann dadurch verhindert werden. Außerdem kann mit einer Bewegung der Umlenkeinheit nach oben besonders viel Faserband zwischengespeichert werden.It is advantageous if the deflection unit is movable in a first direction along the direction of gravity. Gravity causes the sliver to sag and form a loop as the delivery unit delivers sliver faster than the receiving unit can receive. If the loop is large enough, the sliver is on a substrate between the delivery unit and the receiving unit, whereby the sliver is dirty or damaged and can knot. The deflection unit can, for example, against gravity, ie upwards away from the ground, are moved, so that the sliver is deflected away from the ground. A ground contact of the sliver can be prevented. In addition, with a movement of the deflection up particularly much sliver can be cached.
Vorteilhaft ist es auch, wenn die Umlenkeinheit in einer zweiten Richtung senkrecht zur Schwerkraftrichtung und parallel entlang einer Verbindungsachse zwischen Liefereinheit und Empfangseinheit bewegbar ist. Die Umlenkeinheit kann dadurch beispielsweise zwischen der Liefereinheit hin und her bewegt werden. Dadurch kann Faserband zwischengespeichert werden, wenn in der Umgebung des Textilmaschinenverbunds nicht viel Platz vorhanden ist. Der Textilmaschinenverbund kann dadurch platzsparend ausgebildet werden.It is also advantageous if the deflecting unit is movable in a second direction perpendicular to the direction of gravity and parallel along a connecting axis between the delivery unit and the receiving unit. The deflection unit can thereby be moved back and forth, for example, between the delivery unit. As a result, sliver can be cached, if not much space is available in the environment of the textile machine network. The textile machine composite can be designed to save space.
Ebenso kann es vorteilhaft sein, wenn die Umlenkeinheit in einer dritten Richtung senkrecht zur Schwerkraftrichtung und senkrecht zur Verbindungsachse bewegbar ist. Die Umlenkeinheit kann somit quer zwischen der Liefereinheit und der Empfangseinheit bewegt werden. Dadurch kann das Faserband seitlich abgelenkt werden.Likewise, it may be advantageous if the deflection unit is movable in a third direction perpendicular to the direction of gravity and perpendicular to the connection axis. The deflection unit can thus be moved transversely between the delivery unit and the reception unit. As a result, the sliver can be deflected laterally.
Von Vorteil ist es, wenn die Umlenkeinheit derart bewegbar ist, dass sich die erste, die zweite und/oder die dritte Richtung überlagern. Dadurch kann die Umlenkeinheit beliebig im Raum bewegt werden. Ist beispielsweise eine weitere Bewegung der Umlenkeinheit in erster Richtung, beispielsweise nach oben, nicht mehr möglich, kann die Umlenkeinheit beispielsweise in die dritte Richtung bewegt werden. Dadurch ist eine Flexibilität in der Bewegung der Umlenkeinheit erhöht.It is advantageous if the deflection unit is movable such that the first, the second and / or the third direction are superimposed. This allows the deflection can be moved anywhere in the room. If, for example, further movement of the deflection unit in the first direction, for example upwards, is no longer possible, the deflection unit can be moved, for example, in the third direction. This increases flexibility in the movement of the deflection unit.
Vorteilhaft ist es, wenn die Umlenkeinheit um eine Entfernung bewegbar ist, die mindestens 50% des Abstands zwischen Liefereinheit und Empfangseinheit entspricht. Die Entfernung, um die die Umlenkeinheit bewegbar ist, kann auch mindestens 100% des Abstands zwischen Liefereinheit und Empfangseinheit entsprechen. Dadurch kann genügend Faserband zwischengespeichert werden, um einen zeitweisen Unterschied zwischen Liefergeschwindigkeit und Empfangsgeschwindigkeit auszugleichen.It is advantageous if the deflecting unit is movable by a distance which corresponds to at least 50% of the distance between the delivery unit and the receiving unit. The distance by which the deflection unit is movable may also correspond to at least 100% of the distance between the delivery unit and the reception unit. As a result, enough sliver can be cached to compensate for a temporary difference between delivery speed and receiving speed.
Von Vorteil ist es, wenn die zumindest eine Bandspeichereinheit einen Aktor aufweist, mittels dem die Umlenkeinheit bewegbar ist. Dadurch kann die Umlenkeinheit automatisiert bewegt werden.It is advantageous if the at least one band storage unit has an actuator, by means of which the deflection unit is movable. As a result, the deflection can be moved automatically.
Des Weiteren ist es vorteilhaft, wenn der Aktor einen Hydraulikaktor, einen Pneumatikaktor, einen Elektromotor, einen Schrittmotor und/oder einen Stellmotor umfasst.Furthermore, it is advantageous if the actuator comprises a hydraulic actuator, a pneumatic actuator, an electric motor, a stepper motor and / or a servomotor.
Zusätzlich oder alternativ ist es vorteilhaft, wenn die Umlenkeinheit an einer Verlängerung angeordnet ist, die mittels des Aktors bewegbar ist. Zusätzlich oder alternativ kann die Verlängerung auch verschwenkbar sein, so dass die Umlenkeinheit verschwenkt werden kann. Die Verlängerung kann auch eine Teleskopstange sein, so dass die Bandspeichereinheit kompakt ausgebildet werden kann, aber die Umlenkeinheit trotzdem um einen weiten Weg bewegbar ist.Additionally or alternatively, it is advantageous if the deflection unit is arranged on an extension which is movable by means of the actuator. Additionally or alternatively, the extension may also be pivotable, so that the deflection unit can be pivoted. The extension may also be a telescopic rod, so that the tape storage unit can be made compact, but the deflection unit is still movable by a long way.
Von Vorteil ist es, wenn die Umlenkeinheit eine Rolle umfasst. Über die Rolle kann das Faserband laufen. Dadurch kann das Faserband gut umgelenkt werden. Die Rolle kann auch mit Hilfe eines Antriebs angetrieben sein, so dass die Rolle das Faserband aktiv weiterleitet.It is advantageous if the deflection unit comprises a roller. About the role of the sliver can run. This allows the sliver to be well diverted. The roller may also be driven by means of a drive, so that the roller actively passes the sliver.
Des Weiteren ist es von Vorteil, wenn der Textilmaschinenverbund eine Steuerung umfasst, die zum Datenaustausch mit der Liefereinheit verbunden ist. Zusätzlich oder alternativ kann die Steuerung auch mit der Empfangseinheit zum Datenaustausch verbunden sein. Beispielsweise kann die Steuerung die Liefergeschwindigkeit der Liefereinheit und/oder die Empfangsgeschwindigkeit der Empfangseinheit erhalten. Zusätzlich oder alternativ kann die Steuerung einen Zeitpunkt eines bevorstehenden Kannenwechsels erhalten. Beispielsweise im Zusammenhang mit einem Kannenwechsel an der als Strecke ausgebildeten Empfangseinheit kann die Steuerung ermitteln, wie die Umlenkeinheit bewegt werden muss, um Faserband zwischenzuspeichern, um eine Absenkung der Empfangsgeschwindigkeit auszugleichen. Die Steuerung kann dabei auch die Empfangsgeschwindigkeit drosseln oder stoppen.Furthermore, it is advantageous if the textile machine network comprises a controller, which is connected to the data exchange with the delivery unit. Additionally or alternatively, the controller may also be connected to the receiving unit for data exchange. For example, the controller may receive the delivery speed of the delivery unit and / or the receiving speed of the receiving unit. Additionally or alternatively, the controller may receive a time of imminent can change. For example, in connection with a can change on the receiving unit designed as a route, the controller can determine how the deflection unit has to be moved in order to buffer sliver in order to compensate for a decrease in the receiving speed. The controller can also throttle or stop the reception speed.
Des Weiteren wird eine Textilmaschine vorgeschlagen, die beispielsweise eine Karde sein kann. Die Textilmaschine umfasst eine Liefereinheit, mittels der ein Faserband beim Betrieb der Liefereinheit geliefert wird. Außerdem umfasst die Textilmaschine zumindest eine Bandspeichereinheit, die bei einer Liefergeschwindigkeit des Faserbandes an der Liefereinheit, die höher ist als eine Empfangsgeschwindigkeit des Faserbandes an einer Empfangseinheit einer weiteren Textilmaschine, das überschüssige Faserband zwischen der Liefereinheit und der Empfangseinheit zumindest zeitweise zwischenspeichert. Bei einer Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit, die höher ist als die Liefergeschwindigkeit des Faserbandes an der Liefereinheit, kann das Faserband von der Bandspeichereinheit freigegeben werden.Furthermore, a textile machine is proposed, which may be for example a card. The textile machine comprises a delivery unit, by means of which a sliver is supplied during operation of the delivery unit. In addition, the textile machine comprises at least one belt storage unit, which at a delivery speed of the sliver to the delivery unit, which is higher than a receiving speed of the sliver at a receiving unit of another textile machine, the excess sliver between the delivery unit and the receiving unit at least temporarily stores. At a receiving speed of the sliver at the receiving unit, which is higher than the delivery speed of the sliver on the delivery unit, the sliver can be released from the tape storage unit.
Erfindungsgemäß weist die Bandspeichereinheit zumindest eine gegenüber der Liefereinheit bewegbare Umlenkeinheit auf, mit deren Hilfe das Faserband umlenkbar ist und mittels der ein Faserbandweg für das Faserband von der Liefereinheit zur Empfangseinheit veränderbar ist.According to the invention, the band storage unit has at least one deflection unit movable relative to the delivery unit, with the aid of which the sliver can be deflected and by means of which a sliver path for the sliver can be changed from the delivery unit to the receiving unit.
Dabei kann vorzugsweise die Bandspeichereinheit ein oder mehrere Merkmale gemäß vorangegangener und/oder nachfolgender Beschreibung aufweisen.In this case, the band storage unit may preferably have one or more features according to the preceding and / or following description.
Des Weiteren können die Textilmaschine, die die Liefereinheit umfasst, und die weitere Textilmaschine, die die Empfangseinheit umfasst, den oben beschriebenen Textilmaschinenverbund bilden.Furthermore, the textile machine comprising the delivery unit and the further textile machine comprising the receiving unit can form the textile machine assembly described above.
Ferner wird eine Textilmaschine vorgeschlagen, die beispielsweise eine Strecke sein kann. Die Textilmaschine umfasst eine Empfangseinheit, mittels der ein Faserband beim Betrieb der Empfangseinheit empfangen wird. Außerdem umfasst die Textilmaschine zumindest eine Bandspeichereinheit, die bei einer Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit, die niedriger ist als eine Liefergeschwindigkeit des Faserbandes an einer Liefereinheit einer weiteren Textilmaschine, das überschüssige Faserband zwischen der Liefereinheit und der Empfangseinheit zumindest zeitweise zwischenspeichert. Die weitere Textilmaschine kann beispielsweise eine Karde sein. Die Bandspeichereinheit kann ebenso bei einer Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit, die höher ist als die Liefergeschwindigkeit des Faserbandes an der Liefereinheit, das zwischengespeicherte Faserband freigeben.Further, a textile machine is proposed, which may for example be a route. The textile machine comprises a receiving unit, by means of which a sliver is received during operation of the receiving unit. In addition, the textile machine comprises at least one tape storage unit, which at a receiving speed of the sliver at the receiving unit, which is lower than a delivery speed of the sliver at a delivery unit of another textile machine, the excess sliver between the supply unit and the receiving unit at least temporarily stores. The further textile machine may for example be a card. The tape storage unit may also release the cached sliver at a receiving speed of the sliver at the receiving unit that is higher than the delivery speed of the sliver at the delivery unit.
Erfindungsgemäß weist die Bandspeichereinheit zumindest eine gegenüber der Empfangseinheit bewegbare Umlenkeinheit auf, mit deren Hilfe das Faserband umlenkbar ist und mittels der ein Faserbandweg für das Faserband von der Liefereinheit zur Empfangseinheit veränderbar ist.According to the invention, the band storage unit has at least one deflecting unit which is movable relative to the receiving unit and with the aid of which the sliver can be deflected and by means of which a sliver path for the sliver can be changed from the delivery unit to the receiving unit.
Dabei kann vorzugsweise die Bandspeichereinheit ein oder mehrere Merkmale gemäß vorangegangener und/oder nachfolgender Beschreibung aufweisen.In this case, the band storage unit may preferably have one or more features according to the preceding and / or following description.
Des Weiteren können die Textilmaschine, die die Empfangseinheit umfasst, und die weitere Textilmaschine, die die Liefereinheit umfasst, den oben beschriebenen Textilmaschinenverbund bilden.Furthermore, the textile machine comprising the receiving unit and the further textile machine comprising the delivery unit can form the textile machine assembly described above.
Vorgeschlagen wird ferner ein Verfahren zum Zwischenspeichern eines Faserbandes an einem Textilmaschinenverbund. Der Textilmaschinenverbund kann gemäß zumindest einem Merkmal der vorangegangenen und/oder nachfolgenden Beschreibung ausgebildet sein.Also proposed is a method for temporarily storing a sliver on a textile machine composite. The textile machine composite can be designed according to at least one feature of the preceding and / or following description.
Der Textilmaschinenverbund umfasst eine Liefereinheit, mittels der beim Betrieb der Liefereinheit ein Faserband geliefert wird. Die Liefereinheit kann beispielsweise eine Karde sein, die ein Faserband liefert. Die Liefereinheit kann aber auch eine andere Einheit des Textilmaschinenverbunds sein. Die Liefereinheit stellt das Faserband bereit.The textile machine assembly comprises a delivery unit, by means of which a sliver is supplied during operation of the delivery unit. The delivery unit can be for example a card which delivers a sliver. The delivery unit can also be another unit of the textile machine network. The delivery unit provides the sliver.
Ferner umfasst der Textilmaschinenverbund eine Empfangseinheit, mittels der das von der Liefereinheit gelieferte Faserband beim Betrieb der Empfangseinheit empfangen wird. Die Empfangseinheit kann beispielsweise eine Strecke sein. Die Empfangseinheit kann aber auch eine andere Einheit des Textilmaschinenverbunds sein. Die Empfangseinheit empfängt das Faserband, um es beispielsweise weiterzuleiten und/oder zu verarbeiten.Furthermore, the textile machine network comprises a receiving unit, by means of which the sliver supplied by the delivery unit is received during operation of the receiving unit. The receiving unit may be, for example, a route. The receiving unit can also be another unit of the textile machine network. The receiving unit receives the sliver, for example, to forward and / or process it.
Außerdem umfasst der Textilmaschinenverbund eine Bandspeichereinheit, die bei einer Liefergeschwindigkeit des Faserbandes an der Liefereinheit, die höher ist als eine Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit, das überschüssige Faserband zwischen der Liefereinheit und der Empfangseinheit zumindest zeitweise zwischenspeichert.In addition, the textile machine assembly comprises a tape storage unit, which at a delivery speed of the sliver on the delivery unit, which is higher than a receiving speed of the sliver at the receiving unit, the excess sliver between the supply unit and the receiving unit, at least temporarily stores.
Ebenso kann die Bandspeichereinheit bei einer Empfangsgeschwindigkeit des Faserbandes an der Empfangseinheit, die höher ist als die Liefergeschwindigkeit des Faserbandes an der Liefereinheit, das zwischengespeicherte Faserband freigeben.Likewise, at a receiving speed of the sliver at the receiving unit that is higher than the delivery speed of the sliver at the delivery unit, the band storage unit may release the buffered sliver.
Erfindungsgemäß weist die Bandspeichereinheit zumindest eine gegenüber der Liefereinheit bewegbare Umlenkeinheit auf, mit deren Hilfe das Faserband zumindest zeitweise umgelenkt wird. Die Umlenkeinheit kann zusätzlich oder alternativ auch gegenüber der Empfangseinheit bewegt werden. Mittels der Umlenkeinheit wird ein Faserbandweg für das Faserband von der Liefereinheit zur Empfangseinheit verändert, wenn Faserband zwischengespeichert oder wieder freigegeben werden soll.According to the invention, the band storage unit has at least one deflection unit which is movable relative to the delivery unit and with the aid of which the sliver is deflected at least temporarily. The deflecting unit can additionally or alternatively also be moved relative to the receiving unit. By means of the deflection unit, a sliver path for the sliver is changed from the delivery unit to the receiving unit when sliver is to be buffered or released again.
Der Faserbandweg kann der Weg sein, den das Faserband von der Liefereinheit zur Empfangseinheit zurücklegen muss. Der Faserbandweg kann beispielsweise der kürzeste Weg, also der direkte Weg, von der Liefereinheit zur Empfangseinheit sein. Mittels der Umlenkeinheit wird dieser Faserbandweg beispielsweise verlängert, wenn Faserband zwischengespeichert werden soll. Das Faserband muss dadurch einen Umweg von der Liefereinheit zur Empfangseinheit zurücklegen. Zwischen der Liefereinheit und der Empfangseinheit ist dadurch ein größeres Faserbandstück angeordnet, so dass das überschüssige Faserband zwischenspeichert wird.The sliver path may be the path that the sliver must travel from the delivery unit to the receiving unit. The sliver path can, for example, be the shortest path, that is to say the direct route, from the delivery unit to the receiving unit. By means of the deflecting unit, this sliver path is lengthened, for example, if sliver is to be temporarily stored. The sliver must thereby cover a detour from the delivery unit to the receiving unit. As a result, a larger sliver piece is arranged between the delivery unit and the receiving unit, so that the excess sliver is temporarily stored.
Beispielsweise beträgt der direkte Weg von der Liefereinheit zur Empfangseinheit 2 m. Die Umlenkeinheit wird nun bewegt, so dass der Faserbandweg verlängert wird. Das Faserband muss beispielweise nun einen Weg von der Liefereinheit zur Empfangseinheit zurücklegen, der 3 m beträgt. Die Differenz von 1 m Faserband ist zwischengespeichert.For example, the direct distance from the delivery unit to the receiving unit is 2 m. The deflection unit is now moved, so that the Faserbandweg is extended. The sliver, for example, now has to cover a distance from the delivery unit to the receiving unit, which is 3 m. The difference of 1 m sliver is buffered.
Bewegt sich die Umlenkeinheit wieder zurück, beträgt der Faserbandweg beispielsweise wieder 2 m. Die zusätzlichen 1 m werden wieder freigegeben. Die überschüssigen 1 m Faserband können von der Empfangseinheit aufgenommen werden, wenn diese schneller das Faserband empfängt als es die Liefereinheit liefert.For example, if the diverting unit moves back, the sliver path is again 2 m. The additional 1 m will be released again. The excess 1 m sliver can be picked up by the receiving unit when it receives the sliver faster than the delivery unit delivers.
In einer vorteilhaften Weiterbildung der Erfindung wird bei einem durchhängenden Faserband die Umlenkeinheit bewegt, so dass der Faserbandweg vergrößert wird. Die Umlenkeinheit kann beispielsweise gegen das durchhängende Faserband nach oben bewegt werden. Dadurch wird das Faserband vorteilhafterweise von einem Untergrund angehoben, so dass es sich nicht auf diesem ablegt.In an advantageous embodiment of the invention, the deflecting unit is moved in a slack sliver, so that the Faserbandweg is increased. The deflection can be moved, for example, against the slack sliver up. As a result, the sliver is advantageously lifted from a substrate, so that it does not deposit on this.
Ebenso ist es von Vorteil, wenn die Umlenkeinheit derart bewegt wird, dass eine durch das durchhängende Faserband bildende Schlaufe verkleinert wird. Dadurch wird es vom Untergrund weg geführt, so dass der größere Abstand zwischen dem Faserband und dem Untergrund wieder zum Zwischenspeichern des Faserbandes bereitstehen kann. Zusätzlich oder alternativ kann die Umlenkeinheit auch derart bewegt werden, dass die Schlaufe in einer Größe konstant bleibt.Likewise, it is advantageous if the deflection unit is moved in such a way that a loop formed by the slack sliver is reduced. As a result, it is guided away from the ground, so that the larger distance between the sliver and the ground can be available again for buffering the sliver. Additionally or alternatively, the deflection unit can also be moved in such a way that the loop remains constant in size.
Vorteilhaft ist es, wenn zum Freigeben des zwischengespeicherten Faserbandes die Umlenkeinheit derart bewegt wird, dass sich der Faserbandweg verkürzt. Die Umlenkeinheit kann beispielsweise entgegen der Richtung bewegt werden, in welche die Umlenkeinheit bewegt wurde, um den Faserbandweg zu vergrößern. Die Umlenkeinheit kann wieder in eine Ausgangsposition zurück bewegt werden.It is advantageous if, in order to release the buffered sliver, the deflection unit is moved in such a way that the sliver path is shortened. For example, the diverting unit may be moved counter to the direction in which the diverting unit has been moved in order to increase the fiber band path. The deflection unit can be moved back to a starting position.

Mittels der Liefereinheit 3 wird im Betrieb des Textilmaschinenverbunds 1 ein Faserband 2 geliefert. Die Liefereinheit 3 kann beispielsweise eine Karde sein, die Textilfasern kardieren kann. Die Liefereinheit 3 kann aber auch eine andere Einheit sein, die das Faserband 2 bereitstellt. Die Liefereinheit 3 kann das Faserband 2 mit einer Liefergeschwindigkeit im Betrieb liefern. Die Liefergeschwindigkeit kann beispielsweise 10 m/min betragen. Es werden also 10 m Faserband pro Minute von der Liefereinheit 3 geliefert.By means of the
Mittels der Empfangseinheit 4 wird beim Betrieb des Textilmaschinenverbunds 1 das von der Liefereinheit 3 gelieferte Faserband 2 empfangen. Gemäß dem vorliegenden Ausführungsbeispiel ist die Empfangseinheit 4 eine Strecke, die ein Streckwerk 5 aufweist. Die Empfangseinheit 4 kann aber auch eine andere Einheit sein, die das Faserband 2 empfängt. Die Empfangseinheit 4 kann gemäß dem vorliegenden Ausführungsbeispiel eine Eingangsrolle 6 aufweisen, mittels der das Faserband 2 in die Empfangseinheit 4 eingeführt werden kann. Die Empfangseinheit 4 kann eine Empfangsgeschwindigkeit aufweisen, mit der die Empfangseinheit 4 das Faserband 2 empfängt. Vorteilhafterweise sind die Liefergeschwindigkeit der Liefereinheit 3 und die Empfangsgeschwindigkeit der Empfangseinheit 4 gleich groß. Dadurch wird zum einen verhindert, dass das Faserband 2 abreißt. Andererseits wird dadurch verhindert, dass das Faserband 2 auf einem Untergrund 12 zwischen der Liefereinheit 3 und der Empfangseinheit 4 abgelegt wird, wobei das Faserband 2 verschmutzen und beschädigt werden kann.By means of the receiving
Sind die Liefergeschwindigkeit und die Empfangsgeschwindigkeit gleich groß, kann das Faserband 2 einen ersten Faserbandweg 7 aufweisen. Der erste Faserbandweg 7 kann ein direkter Weg zwischen einem Austrittspunkt 10 des Faserbandes 2 an der Liefereinheit 3 und einem Eintrittspunkt 11 des Faserbandes 2 an der Empfangseinheit 4 sein. In diesem Fall weist das Faserband 2 den ersten Faserbandweg 7 auf. Dies kann einen normalen Betrieb des Textilmaschinenverbunds 1 darstellen.If the delivery speed and the receiving speed are the same, the
Handelt es sich bei der Empfangseinheit 4 beispielsweise um eine Strecke 4, kann dieser eine hier nicht gezeigte Kanne nachgeordnet sein, in der das von der Strecke 4 verstreckte Faserband 2 abgelegt wird. Nach einer gewissen Zeit wird die Kanne vollständig gefüllt sein und ein Kannenwechsel ist notwendig. Dazu muss die Empfangseinheit 4 kurzzeitig gestoppt oder zumindest kurzzeitig in einer Verarbeitungsgeschwindigkeit abgebremst werden. D.h., die Empfangseinheit 4 kann das Faserband 2 nur noch langsamer empfangen oder, wenn diese gestoppt wird, gar nicht empfangen. Die Empfangsgeschwindigkeit der Empfangseinheit 4 ist im Vergleich zur Empfangsgeschwindigkeit im normalen Betrieb geringer. Wenn die Liefereinheit 3 das Faserband 2 jedoch mit einer unveränderten Liefergeschwindigkeit liefert und somit die Liefergeschwindigkeit höher ist als die Empfangsgeschwindigkeit, bildet sich gemäß
Gemäß
Die Bandspeichereinheit 13 weist eine Verlängerung 15 auf, an deren Ende die Umlenkeinheit 14 angeordnet ist. Die Bandspeichereinheit 13 kann einen hier nicht gezeigten Aktor umfassen, mittels dem die Verlängerung 15 bewegbar ist, so dass die Umlenkeinheit 14 bewegt werden kann. Der Aktor kann beispielsweise ein Hydraulikaktor, ein Pneumatikaktor, ein Elektromotor und/oder ein Schrittmotor sein, wobei der Aktor mit einer Steuerung 17 steuerbar ist, um die Umlenkeinheit 14 zu bewegen. Die Verlängerung 15 kann beispielsweise eine Teleskopstange sein, so dass die Umlenkeinheit 14 noch weiter bewegt werden kann.The
Der Textilmaschinenverbund 1 kann ferner die Steuerung 17 aufweisen, die die Umlenkeinheit 14 bewegen kann. Die Steuerung 17 kann beispielsweise Information von der Liefereinheit 3 und/oder der Empfangseinheit 4 erhalten. Beispielsweise kann die Steuerung 17 die Liefergeschwindigkeit des Faserbands 2 an der Liefereinheit 3 erhalten. Zusätzlich oder alternativ kann die Steuerung 17 auch die Empfangsgeschwindigkeit des Faserbands 2 an der Empfangseinheit 4 erhalten. Die Steuerung 17 kann daraus beispielsweise die Differenz berechnen. Daraus kann die Steuerung 17 berechnen, wieviel Faserband 2 zwischengespeichert werden soll. Die Steuerung 17 kann entsprechend die Umlenkeinheit 14 bewegen.The textile machine assembly 1 may further comprise the
Der erste Faserbandweg 7 gemäß der
Die Umlenkeinheit 14 kann beispielsweise zu einem Zeitpunkt in erster Richtung Z gegen die Schwerkraftrichtung S bewegt werden, wenn die Empfangsgeschwindigkeit an der Empfangseinheit 4 unter die Liefergeschwindigkeit an der Liefereinheit 3 fällt. Das Faserband 2 wird somit gleichzeitig nach oben gezogen, wenn mehr Faserband 2 von der Liefereinheit 3 geliefert wird, als von der Empfangseinheit 4 aufgenommen werden kann. Dieser Fall tritt beispielsweise ein, wenn die Empfangseinheit 4 eine Strecke ist und ein Kannenwechsel begonnen wird.The
Die Umlenkeinheit 14 kann sich auch erst in erster Richtung Z gegen die Schwerkraftrichtung S bewegen, wenn sich die Schlaufe 9 gebildet hat. Erst wenn sich beispielsweise die Schlaufe 9 gemäß dem Ausführungsbeispiel der
Wenn das Faserband 2 wieder freigegeben werden soll, kann die Umlenkeinheit 14 wieder zurück in die Ausgangsposition bewegt werden. Gemäß
Zusätzlich oder alternativ kann die Umlenkeinheit 14 noch entlang einer dritten Richtung Y bewegt werden, die hier jedoch nicht gezeigt ist. In dieser Seitenansicht des Textilmaschinenverbunds 1 ist die dritte Richtung Y aus der Zeichenebene hinaus oder hinein orientiert. Die Umlenkeinheit 14 kann somit entlang der dritten Richtung Y seitlich bewegt werden.Additionally or alternatively, the
