Definitions
- the present invention relates to a device for temporarily storing band-like weft material for a weaving machine.
- a weaving machine for processing band-like weft material shows, for example, the EP 1838911 A1 , It also discloses an apparatus for feeding the ribbon-like weft material to a weft insertion member. The weft material is withdrawn intermittently at each weft insertion cycle of the loom from one or more driven supply reels.
- the device according to EP 1838911 A1 has the disadvantage that at higher take-off speeds in a very short time the supply reels must be accelerated and slowed down. It is therefore customary to provide temporary storage for the weft material.
- An apparatus suitable for this purpose shows, for example, the DE 103 15 347 A1 , This relates to the temporary storage of fibers which are discontinuously withdrawn from a supply reel and fed to a production line. An example of such a production line is called weaving.
- a similar device also shows the JP 2001329452 A , In the DE 103 15 347 A1 and in the JP 2001329452 A However, the buffers are arranged such that the weft material is deflected when deducting between the loop in the storage container and the production line in the loom by 90 degrees. However, deflections are detrimental to some weft materials.
- Band-like carbon fiber wefts should be deflected as little as possible in the production process, since the very brittle carbon fibers are at risk of breaking at each deflection and since the composite of the ribbon-like weft material can be undesirably dissolved during diversion.
- a device for the selection of tape-like weft materials from two different yarn stocks is in the DE 10 2009 036589 A1 disclosed.
- the EP 1838911 A1 shows two supply spools from which ribbon-like weft material is unrolled and fed to a shed.
- Means for temporarily storing the two weft materials are in the EP 1838911 A1 and in the DE 10 2009 036589 A1 not revealed. Accordingly, it is not known from the state of the art how the supply of weft material from an electrically driven supply reel to a weaving machine via a temporary store is to be effected if alternating tape-like weft material is to be withdrawn alternately from two different supply reels and entered.
- Object of the present invention is to provide a device for temporarily storing band-like weft material for a loom, which are reduced by the device deflections of the weft material on the way to the loom.
- This device serves to temporarily store two tape-like weft materials for a weaving machine.
- ribbon-like weft material here is meant flexible material whose width is several times greater than its thickness. It may be a homogeneous material or a composite of many individual fibers.
- the first and the second weft material are respectively mounted on a first and a second supply reel, which are each driven by a first or second drive means about an axis of rotation.
- the device has a first storage container with an opening for the first weft material.
- This opening can be designed so that thereby supplied to the storage container shot material and can also be removed from the storage container.
- the storage container has a cover instead of a single opening, which has two openings. One of them can then be used for the supply of weft material to the storage container, while the other is used for the discharge of the weft material.
- the first storage container has an interior which is bounded by two narrow sides. These two narrow sides extend in a longitudinal direction of the first storage container. These narrow sides are otherwise formed so that between them a U-shaped loop of the first weft material can be formed. This means that the narrow sides of the diameter of the trainees U-shaped loop of the weft material is limited. It does not matter whether the narrow sides are closed walls or merely limiting elements of the interior, which are arranged in such a way that leakage of the U-shaped loop from the interior is prevented. Furthermore, means for applying a first tensile force to the first weft material are present.
- the apparatus further comprises a first deflecting element, which is arranged such that the first shot material can be fed via the first deflecting element through the opening for the first shot material to the interior of the first storage container.
- the first deflecting element can be designed, for example, as a deflection roller or in otherwise suitable form. As a rule, the first deflecting element is mounted between the first supply reel and the first storage container.
- the device according to the invention is characterized by a second storage container having an opening for the second weft material.
- the second storage container has an inner space which is delimited by two narrow sides such that a U-shaped loop of the second weft material can be formed between these narrow sides.
- the two narrow sides of the second storage container extend in a longitudinal direction of the second storage container.
- there are means for applying a second tensile force to the second weft material wherein the second tensile force in the longitudinal direction of the second storage container points from the opening for the second weft material into the interior of the second storage container.
- a second deflection element is provided, which is arranged such that the second weft material can be fed via the second deflection element through the opening to the interior of the second storage container.
- the second deflecting element is mounted between the second supply spool and the second storage container.
- both storage containers are arranged such that the two weft materials can be supplied from the same direction through the respective openings to the storage containers.
- Such an arrangement results when the openings of the storage containers facing in the same direction with respect to the entire device. Then, the shot materials can be removed again in this direction through the respective openings.
- the arrangement according to the invention is chosen so that the interiors of the two storage containers each turn to one of the two narrow sides. Finally, the narrow sides of the two interiors are parallel to each other at least in their width. This ensures that the two ribbon-like weft materials in the width direction of the weft material parallel to each other.
- the two deflecting elements are each arranged such that the respective weft material passes through the opening for this weft material to the interior of the respective storage container in an area can be fed, which - with respect to the two narrow sides of this interior - closer to that of the two narrow sides of this interior, which does not face the interior of the respective other storage container.
- the arrangement according to the invention is particularly advantageous because it is not possible according to two devices for feeding weft material DE 103 15 347 A1 or JP 2001329452 A easy to arrange next to the loom in the warp direction one behind the other.
- Such arrangements would be suitable only for normal weft yarn, which is not designed like a belt, since with such weft yarn deflection in all directions transverse to the course of the weft yarn can be allowed.
- deflections in the direction of the widthwise extension of the belt are in principle not possible, since the belt would thereby be damaged or twisted.
- the width extension of a band-like weft material extends in a weaving machine usually in the warp direction.
- the necessary supply and intermediate storage devices can not be arranged one behind the other in the warp direction, since at least one of the two weft materials would require a deflection in width of the belt in order to bring this into the line of movement of the weft insertion element on the loom.
- the device according to the invention provides a remedy here.
- both storage containers can be designed, for example, as elongated hollow bodies.
- the longitudinal axes of the storage container extending substantially in the direction of the tensile forces.
- the interior may have a rectangular inner cross-section.
- the shorter axis of symmetry of this inner cross section can have approximately the length of the width extension of the band-like weft material to be stored.
- the device in operation, is covered with ribbon-like weft material in such a way that the widthwise extension of the strip extends parallel to the shorter axis of symmetry of the inner cross section.
- the length of the longer symmetry axis of such a rectangular inner cross section corresponds to the distance of the narrow sides of the interior.
- This distance determines the radius of curvature with which the weft material in Storage tank is deflected U-shaped.
- a larger distance requires more space, but protects the weft material at the deflection point in the storage container.
- Very small deflections can be generated on the way to the loom, for example, by providing guide elements for the weft material, which are arranged or adjusted such that the respective weft material from the associated storage container with respect to the narrow sides of a region of the relevant interior is discharged, each of which is closer to that narrow side, which faces the respective other storage container.
- existing or additional deflection elements or the side walls of the interior can serve as guide elements.
- separate guide elements may also be provided for the purpose described herein. Thus, both shot materials are discharged close to each other from the device.
- the device has one or more guide elements which are arranged and / or adjustable such that the two weft materials are guided at least at the output, so when removing from the device such that a line of symmetry, halfway Width of the first weft material perpendicular to the surface thereof, lies in a plane with a line of symmetry, which extends at half the width of the second weft material perpendicular to the surface thereof.
- a line of symmetry, halfway Width of the first weft material perpendicular to the surface thereof lies in a plane with a line of symmetry, which extends at half the width of the second weft material perpendicular to the surface thereof.
- the two symmetry lines of the two weft materials lie in one plane.
- existing or additional elements or the side walls of the interior can serve as guide elements, if they are designed or arranged accordingly.
- the narrow sides of the interiors of the storage container in its width extension extend parallel to the direction of the axes of rotation of the supply reels, since then between supply reels and interiors a torsion-free running of the weft material is possible.
- Particularly advantageous is an arrangement of storage containers and deflecting elements, which is constructed partly or completely mirror-inverted to a longitudinally oriented, lying in the middle between the two storage tanks center line.
- This mirror-image construction makes it possible to remove the two weft materials in the vicinity of the center line from the device and feed them to a weaving machine without further deflections of the weft materials occurring. With this arrangement, it follows that all four narrow sides of the two inner spaces lie in mutually parallel planes.
- the storage containers may be designed, for example, as storage shafts with openings for the weft material at in each case one of the shaft ends.
- the device may further be equipped with a vacuum device for exerting the tensile forces on the two weft materials.
- the negative-pressure device is designed, for example, so that a negative pressure can be generated either in the first or in the second or in both storage containers.
- a switching device is used.
- a single vacuum device for example a vacuum pump - to pressurize both storage tanks alternately or simultaneously with negative pressure.
- a vacuum pump for example a vacuum pump
- negative pressure device for each one storage container, with which also the above-described alternating operation and possibly also different negative pressures in the two storage containers are possible.
- the tensile force can also be exerted by a spring device which exerts a pulling force on the weft material via a movable deflection element.
- a spring device which exerts a pulling force on the weft material via a movable deflection element.
- one end of a spring is connected to the storage container and the other to the movable deflecting element.
- the two storage containers of the device for temporarily storing the two ribbon-like weft materials on a weaving machine in such a way that the two pulling forces run parallel to a weft direction of the weaving machine.
- the weft material can thus be supplied from the storage container to the weft insertion element without a deflection by 90 degrees.
- It can also be arranged symmetrically to a line which extends substantially in the extension of a line of movement of a weft insertion member of the loom, the two interiors of the storage container.
- the loom with the device for temporary storage of the two ribbon-like weft materials also a selection device is provided which between the openings of the two storage tanks for the two weft materials and the entrance of a shed of the weaving machine is arranged and with which either the first or the second weft material can be fed to the weft insertion element of the weaving machine.
- FIGS. 1 and 2 show an embodiment of the device according to the invention for temporarily storing two tape-like weft materials 1, 21 to a loom 3.
- the first belt-like weft material 1 is fed via a first fixed deflection pulley 16, which works as a deflection, a shaft-like first storage tank 7 with an opening 8 at one of the shaft ends.
- a first fixed deflection pulley 16 which works as a deflection
- a shaft-like first storage tank 7 with an opening 8 at one of the shaft ends.
- the first weft material 1 is withdrawn from a first supply reel 5, which is arranged rotatably about a rotation axis 6.
- the first supply reel 5 can be driven in a known manner about its axis of rotation 6.
- the control or control of the drive device 4 takes place with the aid of a controller, not shown.
- the first weft material 1 forms in the interior 9 of the first storage container 7 a U-shaped loop 12, which is guided in the present embodiment by a movable loop roller.
- the first weft material 1 is again guided outwardly through the opening 8 of the first storage container 7 in the direction of the loom 3.
- the inner space 9 of the first storage container 7 is delimited by two narrow sides 10, 11 which are at a distance from each other sufficient to allow the U-shaped loop 12 to be formed around the movable loop roll.
- Embodiments without a movable loop roll have become known in the prior art in which the U-shaped loop is freely formed in the interior. However, this has certain disadvantages, so it should not be discussed further here.
- the distance between the two narrow sides 10, 11 is slightly larger than the diameter of the movable loop roller. This ensures that this movable loop roller can move in the longitudinal direction 13 of the storage container 7.
- the movable loop roller is so wide that it can absorb and deflect the U-shaped loop 12 of the first belt-like weft material 1 in its entire width.
- the movable loop roll is additionally equipped with ribs 18 for guiding the two side edges of the ribbon-like weft material 1.
- the width of the inner space 9 is slightly larger than the width of the movable loop roller.
- the two sides of the interior 9, which limit the width of the interior 9, are closed by covers. This is required so that a negative pressure can be built up in the interior 9, through which a pulling force 15 is exerted on the weft material 1 in the storage container 7.
- the side cover may be dispensable.
- a negative pressure in the interior 9 of the storage container 7 is generated by a vacuum device 14 in the form of a vacuum pump.

- the suction opening is presently arranged at the end of the shaft-like storage container 7, which faces away from the opening 8 for the weft material 1; it is closed with a sieve-like grid.
- the weft material 1 with the movable loop roller is sucked away from the opening 8 into the first storage container 7; a pulling force 15 is exerted on the weft material. It is customary to control the drive device 4 for the first supply reel 5 so that the movable loop reel can only be sucked in up to a certain position. This position is determined in a known manner via corresponding sensors on the storage container 7 and passed on to the control of the first drive means 4 on.
- FIGS. 1 and 2 There is a second storage container 27, a fixed second guide roller 36 and a movable loop roller present.
- the second weft material 21 is guided analogously to the first weft material 1, so that it around the movable loop roll around a U-shaped loop 32 forms and is guided through the opening 28 of the second storage container 27 back out in the direction of the loom 3.
- a second supply reel 25 is present, from which a second ribbon-like weft material 21 is pulled off.
- the second supply reel 25 is then rotatably arranged about a rotation axis 26 and with the aid of a second drive device 24, the second supply reel 25 can be driven in a known manner about this axis of rotation 26.
- the drive is also carried out by means of a control, not shown, which communicates with the control for the first drive means 4 of the first supply reel 5 signal in communication.
- the interior 29 of the second storage container 27 is bounded analogously to the interior 9 of the first storage container 7 by two narrow sides 30, 31 and two lids whose distances are based on the dimensions of the U-shaped loop 32 and the movable loop roll.
- the dimensions of the second movable loop roll are selected with respect to the second weft material 21 from the same viewpoint as the first movable loop roll for the first weft material 1. Similar to the shelves 18 of the first loop roll, shelves 38 are attached to the second loop roll.
- a tensile force 35 is exerted in the second storage container 27. This is done in the present case by the same vacuum device 14, which also provides for the negative pressure in the first storage tank 7.
- the vacuum device 14 can optionally be brought into communication with the suction port of the first or the second storage container 7, 27 or simultaneously with both suction pressure.
- a separate second vacuum device 34 for the second storage container 7 As a result of the negative pressure, the second weft material 21 with the movable loop roller is also sucked away from the opening 28 into the second storage container 27.
- the position control of the second U-shaped loop 32 and the second movable loop roller in the withdrawal of the second weft material 21 by the loom 3 is analogous to the position control in the first storage container. 7 by means of corresponding - not shown - sensors on the second storage container 27 and by the control of the drive means 24 for the second supply reel 25th
- FIGS. 1 and 2 show that the two storage containers 7, 27 are arranged so that the two inner spaces 9, 29 each one of its two narrow sides 10, 30 turn.
- the device is equipped with a partition wall 20 between the two storage containers 7, 27.
- This partition 20 forms with two of its longitudinal sides, the two narrow sides 10, 30, each of the two inner spaces 9, 29 of the storage container 7, 27 limit.
- the narrow sides 10, 11, 30, 31 extend in planes which are parallel to one another.
- the two deflecting elements 16, 36 - in the present case designed as deflection rollers mounted fixedly on the respective storage container 7, 27 - are arranged such that the respective weft material 1, 21 is associated with the associated storage container 7, 27 with respect to the narrow sides 10, 11, 30, 31 in FIG a region 17, 37 of the respective interior space 9, 29 is supplied, each of which is closer to that narrow side 11, 31, which faces away from the respective other storage container 7, 27.
- the associated supply reels 5, 25 and drive devices 4, 24 are arranged in the present example on the side of the respective storage container 7, 27, which faces away from the respective other storage container 7, 27. As already explained above, however, other positions of the supply reels 5, 25 are conceivable.
- the device has a center line 41 or mirror line, which extends in the longitudinal direction 13, 33 of the storage container 7, 27 in the middle between the two facing narrow sides 10, 30 of the interior spaces 9, 29.
- this center line 41 is within the partition 20 between the two inner spaces 9, 29 at half the width of the supplied ribbon-like weft material 1.21 or half the width of the two inner spaces 9, 29th.
- a particularly compact design results from the integration of the two storage containers 7, 27 in a housing with a common partition wall 20 and with an arrangement of the openings 8, 28 for the weft material 1, 21 in a plane at one end of the shaft-like storage container 7, 27th (see. FIG. 3 ).

- the device can also be used on looms in which the warp threads are vertical and the weft threads are horizontal. This arrangement is not shown here in figures.
- the width of the weft material also extends in such a case in the direction of the warp threads - thus vertically. Accordingly, the axes of rotation of the two supply spools also run most expediently vertically in this case, and the storage containers are arranged horizontally next to one another.
- FIG. 3 illustrates that the two weft materials 1, 21 when passing through the device according to the FIGS. 1 and 2 be guided such that a line of symmetry 2, which extends at half the width of the first weft material 1 perpendicular to the surface 19, in a plane with a line of symmetry 22 which extends perpendicular to its surface 39 at half the width of the second weft material 21.

- guide elements 18, 38 on the device, which guide the ribbon-like weft material 1, 21 in the direction of its width and / or in the direction of its thickness.
- guide elements 18, 38 are attached to the two storage containers 7, 27 in the region of the openings 8, 28 for the respective weft material 1, 21 for this purpose.
- These guide elements 18, 38 are arranged so that the described type of leadership is guaranteed.
- This guide can also be done by appropriate design of the deflecting elements 16, 36 and / or by rims 18, 38 to the movable loop rollers.
- the guide elements 18, 38 are adjustable so that the type of guidance described above can be optimized.
- the attachment or adjustment of the guide elements 18, 38 is most advantageous such that the respective weft material 1, 21 from the associated storage container 7, 27 with respect to the narrow sides 10, 11, 30, 31 from a region of the respective interior 9, 29 is removed, each of which is closer to that narrow side 10, 30, which faces the respective other storage container 7, 27.
- FIG. 4 shows a weft insertion element 43 a gripper, which is pushed by the shed formed by the warp shed of the loom 3 in the weft direction 40 alternately back and forth.
- the gripper on one side of the loom 3 detects the weft material 1, 21 and pulls it behind in the direction of the entrance of the shed 45 and through it.
- the Weft clamp of the gripper is opened and closed when detecting the weft material 1, 21.

Für den Produktionsprozess an Webmaschinen ist es im Übrigen prinzipiell sinnvoll, das Schussmaterial von zwei verschiedenen Vorratsspulen abzuziehen, auch wenn es sich dabei um das gleiche Material handelt. Wenn eine der beiden Vorratspulen leerläuft, kann die Maschine ohne Unterbrechung weiter arbeiten, während die ausgelaufene Vorratsspule gegen eine volle Spule ausgetauscht wird.For the production process on weaving machines, it makes sense, in principle, to pull off the weft material from two different supply spools, even if they are the same material. If one of the two supply reels runs idle, the machine can continue to operate without interruption while the spilled supply reel is exchanged for a full reel.

Aus dem Stand der Technik ist demnach nicht bekannt, wie die Zuführung von Schussmaterial von einer elektrisch angetriebenen Vorratspule über einen Zwischenspeicher zu einer Webmaschine gelöst wird, wenn abwechselnd von zwei verschiedenen Vorratspulen empfindliches bandartiges Schussmaterial abgezogen und eingetragen werden soll.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Zwischenspeichern von bandartigem Schussmaterial für eine Webmaschine zu schaffen, wobei durch die Vorrichtung Umlenkungen des Schussmaterials auf dem Weg zur Webmaschine reduziert werden.A device for the selection of tape-like weft materials from two different yarn stocks is in the
Also the
Accordingly, it is not known from the state of the art how the supply of weft material from an electrically driven supply reel to a weaving machine via a temporary store is to be effected if alternating tape-like weft material is to be withdrawn alternately from two different supply reels and entered.
Object of the present invention is to provide a device for temporarily storing band-like weft material for a loom, which are reduced by the device deflections of the weft material on the way to the loom.
Die Aufgabe wird durch eine Vorrichtung gemäß dem unabhängigen Anspruch gelöst.
Diese Vorrichtung dient dem Zwischenspeichern von zwei bandartigen Schussmaterialien für eine Webmaschine. Mit bandartigem Schussmaterial ist hier flexibles Material gemeint, dessen Breite um ein mehrfaches größer ist, als seine Dicke. Es kann sich dabei um homogenes Material oder um einen Verbund von vielen Einzelfasern handeln.
In der Regel werden das erste und das zweite Schussmaterial jeweils auf einer ersten und einer zweiten Vorratsspule gelagert, die mit Hilfe einer ersten bzw. zweiten Antriebseinrichtung jeweils um eine Drehachse antreibbar sind.The object is achieved by a device according to the independent claim.
This device serves to temporarily store two tape-like weft materials for a weaving machine. With ribbon-like weft material here is meant flexible material whose width is several times greater than its thickness. It may be a homogeneous material or a composite of many individual fibers.
In general, the first and the second weft material are respectively mounted on a first and a second supply reel, which are each driven by a first or second drive means about an axis of rotation.
Die Vorrichtung weist einen ersten Speicherbehälter mit einer Öffnung für das erste Schussmaterial auf.
Diese Öffnung kann so gestaltet sein, dass dadurch dem Speicherbehälter Schussmaterial zugeführt und auch aus dem Speicherbehälter abgeführt werden kann. Es sind auch Anordnungen denkbar, bei denen der Speicherbehälter anstatt einer einzigen Öffnung einen Deckel aufweist, der zwei Öffnungen besitzt. Eine davon kann dann für die Zufuhr von Schussmaterial zum Speicherbehälter verwendet werden, während die andere der Abfuhr des Schussmaterials dient.The device has a first storage container with an opening for the first weft material.
This opening can be designed so that thereby supplied to the storage container shot material and can also be removed from the storage container. Arrangements are also conceivable in which the storage container has a cover instead of a single opening, which has two openings. One of them can then be used for the supply of weft material to the storage container, while the other is used for the discharge of the weft material.
Der erste Speicherbehälter weist einen Innenraum auf, der durch zwei Schmalseiten begrenzt wird. Diese beiden Schmalseiten erstrecken sich in einer Längsrichtung des ersten Speicherbehälters. Diese Schmalseiten sind im übrigen so ausgebildet, dass zwischen ihnen eine U-förmige Schlaufe des ersten Schussmaterials ausbildbar ist. Das bedeutet, dass durch die Schmalseiten der Durchmesser der auszubildenden U-förmigen Schlaufe des Schussmaterials begrenzt wird. Es spielt dabei keine Rolle, ob es sich bei den Schmalseiten um geschlossene Wände oder lediglich um Begrenzungselemente des Innenraums handelt, die derartig angeordnet sind, dass ein Austreten der U-förmigen Schlaufe aus dem Innenraum verhindert wird.
Weiterhin sind Mittel zum Aufbringen einer ersten Zugkraft auf das erste Schussmaterial vorhanden. Dies kann zum Beispiel eine Unterdruckeinrichtung oder ein federndes Element sein, mit dem auf eine Schlaufe des Schussmaterials eine Zugkraft ausübbar ist. Diese Zugkraft weist in der Längsrichtung des ersten Speicherbehälters von der Öffnung für das erste Schussmaterial nach innen in den Innenraum des ersten Speicherbehälters hinein.
Die Vorrichtung weist weiterhin ein erstes Umlenkelement auf, das derartig angeordnet ist, dass das erste Schussmaterial über das erste Umlenkelement durch die Öffnung für das erste Schussmaterial dem Innenraum des ersten Speicherbehälters zuführbar ist. Das erste Umlenkelement kann dabei zum Beispiel als Umlenkrolle oder in sonst geeigneter Form ausgeführt werden. In der Regel ist das erste Umlenkelement zwischen der ersten Vorratsspule und dem ersten Speicherbehälter angebracht.
Die Vorrichtung ist erfindungsgemäß gekennzeichnet durch einen zweiten Speicherbehälter mit einer Öffnung für das zweite Schussmaterial. Bezüglich der möglichen Anordnung der Öffnungen gilt sinngemäß das gleiche wie bei den Öffnungen des ersten Speicherbehälters.
Der zweite Speicherbehälter weist einen Innenraum auf, der derartig durch zwei Schmalseiten begrenzt wird, dass zwischen diesen Schmalseiten eine U- förmige Schlaufe des zweiten Schussmaterials ausbildbar ist. Die beiden Schmalseiten des zweiten Speicherbehälters erstrecken sich in einer Längsrichtung des zweiten Speicherbehälters.
Weiterhin sind Mittel zum Aufbringen einer zweiten Zugkraft auf das zweite Schussmaterial vorhanden, wobei die zweite Zugkraft in der Längsrichtung des zweiten Speicherbehälters von der Öffnung für das zweite Schussmaterial in den Innenraum des zweiten Speicherbehälters weist.
Weiterhin ist ein zweites Umlenkelement vorhanden, das derartig angeordnet ist, dass das zweite Schussmaterial über das zweite Umlenkelement durch die Öffnung dem Innenraum des zweiten Speicherbehälters zuführbar ist. In der Regel ist das zweite Umlenkelement zwischen der zweiten Vorratsspule und dem zweiten Speicherbehälter angebracht.The first storage container has an interior which is bounded by two narrow sides. These two narrow sides extend in a longitudinal direction of the first storage container. These narrow sides are otherwise formed so that between them a U-shaped loop of the first weft material can be formed. This means that the narrow sides of the diameter of the trainees U-shaped loop of the weft material is limited. It does not matter whether the narrow sides are closed walls or merely limiting elements of the interior, which are arranged in such a way that leakage of the U-shaped loop from the interior is prevented.
Furthermore, means for applying a first tensile force to the first weft material are present. This may be, for example, a vacuum device or a resilient element with which a tensile force can be exerted on a loop of the weft material. This pulling force points inward in the longitudinal direction of the first storage container from the opening for the first shot material into the interior of the first storage container.
The apparatus further comprises a first deflecting element, which is arranged such that the first shot material can be fed via the first deflecting element through the opening for the first shot material to the interior of the first storage container. The first deflecting element can be designed, for example, as a deflection roller or in otherwise suitable form. As a rule, the first deflecting element is mounted between the first supply reel and the first storage container.
The device according to the invention is characterized by a second storage container having an opening for the second weft material. Regarding the possible arrangement of the openings applies mutatis mutandis, the same as in the openings of the first storage container.
The second storage container has an inner space which is delimited by two narrow sides such that a U-shaped loop of the second weft material can be formed between these narrow sides. The two narrow sides of the second storage container extend in a longitudinal direction of the second storage container.
Furthermore, there are means for applying a second tensile force to the second weft material, wherein the second tensile force in the longitudinal direction of the second storage container points from the opening for the second weft material into the interior of the second storage container.
Furthermore, a second deflection element is provided, which is arranged such that the second weft material can be fed via the second deflection element through the opening to the interior of the second storage container. As a rule, the second deflecting element is mounted between the second supply spool and the second storage container.
Erfindungsgemäß sind beide Speicherbehälter derartig angeordnet, dass die beiden Schussmaterialien aus der gleichen Richtung durch die jeweiligen Öffnungen den Speicherbehältern zugeführt werden können. Eine derartige Anordnung ergibt sich, wenn die Öffnungen der Speicherbehälter in Bezug auf die gesamte Vorrichtung in die gleiche Richtung weisen. Dann können durch die jeweiligen Öffnungen die Schussmaterialien auch in diese Richtung wieder abgeführt werden.
Außerdem ist die Anordnung erfindungsgemäß so gewählt, dass die Innenräume der beiden Speicherbehälter einander jeweils eine der beiden Schmalseiten zuwenden.
Schließlich liegen die Schmalseiten der beiden Innenräume zumindest in ihrer Breitenausdehnung parallel zueinander. Dadurch wird erreicht, dass die beiden bandartigen Schussmaterialien in Breitenrichtung des Schussmaterials parallel zueinander verlaufen.According to the invention, both storage containers are arranged such that the two weft materials can be supplied from the same direction through the respective openings to the storage containers. Such an arrangement results when the openings of the storage containers facing in the same direction with respect to the entire device. Then, the shot materials can be removed again in this direction through the respective openings.
In addition, the arrangement according to the invention is chosen so that the interiors of the two storage containers each turn to one of the two narrow sides.
Finally, the narrow sides of the two interiors are parallel to each other at least in their width. This ensures that the two ribbon-like weft materials in the width direction of the weft material parallel to each other.
Erfindungsgemäß ist weiterhin vorgesehen, dass die beiden Umlenkelemente jeweils derartig angeordnet sind, dass das jeweilige Schussmaterial durch die Öffnung für dieses Schussmaterial dem Innenraum des jeweiligen Speicherbehälters in einem Bereich zuführbar ist, der- in Bezug auf die beiden Schmalseiten dieses Innenraums - näher an derjenigen der beiden Schmalseiten dieses Innenraums liegt, die nicht dem Innenraum des jeweils anderen Speicherbehälters zugewandt ist.According to the invention, it is further provided that the two deflecting elements are each arranged such that the respective weft material passes through the opening for this weft material to the interior of the respective storage container in an area can be fed, which - with respect to the two narrow sides of this interior - closer to that of the two narrow sides of this interior, which does not face the interior of the respective other storage container.
Die erfindungsgemäße Anordnung ist besonders vorteilhaft, weil es nicht möglich ist, zwei Vorrichtungen zur Zuführung von Schussmaterial gemäß
Die erfindungsgemäße Vorrichtung schafft hier Abhilfe.The arrangement according to the invention is particularly advantageous because it is not possible according to two devices for feeding weft material
The device according to the invention provides a remedy here.
Bei der erfindungsgemäßen Vorrichtung können beide Speicherbehälter zum Beispiel als lang gestreckte Hohlkörper ausgeführt sein. Die Längsachsen der Speicherbehälter verlaufen dabei im wesentlichen in Richtung der Zugkräfte.
Der Innenraum kann einen rechteckigen Innenquerschnitt aufweisen. Die kürzere Symmetrieachse dieses Innenquerschnitts kann dabei in etwa die Länge der Breitenausdehnung des zu speichernden bandartigen Schussmaterials haben. In diesem Fall wird die Vorrichtung im Betrieb derartig mit bandartigem Schussmaterial belegt, dass sich die Breitenausdehnung des Bandes parallel zur kürzeren Symmetrieachse des Innenquerschnitts erstreckt.
Die Länge der längeren Symmetrieachse eines solchen rechteckigen Innenquerschnitts entspricht dabei dem Abstand der Schmalseiten des Innenraums. Dieser Abstand bestimmt den Krümmungsradius mit dem das Schussmaterial im Speicherbehälter U-förmig umgelenkt wird. Ein größerer Abstand erfordert mehr Platz, schont aber das Schussmaterial am Umlenkpunkt im Speicherbehälter.
Mit einer solchen Anordnung ist es möglich, bandartiges Schussmaterial von zwei verschiedenen Vorratsspulen abzuziehen und einer Webmaschine zuzuführen, ohne dass dabei Umlenkungen in Richtung der Breitenausdehnung des Bandes notwendig werden.In the apparatus according to the invention, both storage containers can be designed, for example, as elongated hollow bodies. The longitudinal axes of the storage container extending substantially in the direction of the tensile forces.
The interior may have a rectangular inner cross-section. The shorter axis of symmetry of this inner cross section can have approximately the length of the width extension of the band-like weft material to be stored. In this case, in operation, the device is covered with ribbon-like weft material in such a way that the widthwise extension of the strip extends parallel to the shorter axis of symmetry of the inner cross section.
The length of the longer symmetry axis of such a rectangular inner cross section corresponds to the distance of the narrow sides of the interior. This distance determines the radius of curvature with which the weft material in Storage tank is deflected U-shaped. A larger distance requires more space, but protects the weft material at the deflection point in the storage container.
With such an arrangement, it is possible to remove band-like weft material from two different supply spools and feed it to a weaving machine without necessitating deflections in the direction of the widthwise extension of the band.
Es können sehr geringe Umlenkungen auf dem Weg zur Webmaschine zum Beispiel dadurch erzeugt werden, dass Führungselemente für das Schussmaterial vorgesehen sind, die derartig angeordnet oder eingestellt sind, dass das jeweilige Schussmaterial aus dem zugehörigen Speicherbehälter in Bezug zu den Schmalseiten aus einem Bereich des betreffenden Innenraums abgeführt wird, der jeweils näher an derjenigen Schmalseite liegt, die dem jeweils anderen Speicherbehälter zugewandt ist. Dabei können vorhandene oder zusätzliche Umlenkelemente oder die Seitenwände des Innenraums als Führungselemente dienen. Es können jedoch auch separate Führungselemente für den hier beschriebenen Zweck vorgesehen werden. Damit werden beide Schussmaterialen dicht beieinander aus der Vorrichtung abgeführt.Very small deflections can be generated on the way to the loom, for example, by providing guide elements for the weft material, which are arranged or adjusted such that the respective weft material from the associated storage container with respect to the narrow sides of a region of the relevant interior is discharged, each of which is closer to that narrow side, which faces the respective other storage container. In this case, existing or additional deflection elements or the side walls of the interior can serve as guide elements. However, separate guide elements may also be provided for the purpose described herein. Thus, both shot materials are discharged close to each other from the device.
Besonders vorteilhaft ist es außerdem, wenn die Vorrichtung ein oder mehrere Führungselemente aufweist, die derartig angeordnet und/oder derartig einstellbar sind, dass die beiden Schussmaterialien zumindest am Ausgang, also beim Abführen aus der Vorrichtung derartig geführt werden, dass eine Symmetrielinie, die auf halber Breite des ersten Schussmaterials senkrecht zu dessen Oberfläche verläuft, in einer Ebene mit einer Symmetrielinie liegt, die auf halber Breite des zweiten Schussmaterials senkrecht zu dessen Oberfläche verläuft. Das bedeutet, dass die beiden Symmetrielinien der beiden Schussmaterialien in einer Ebene liegen. Dadurch wird die umlenkungsarme Zufuhr zu einem Schusseintragselement einer Webmaschine weiter begünstigt.
Auch für diesen Zweck können vorhandene oder zusätzliche Elemente oder die Seitenwände des Innenraums als Führungselemente dienen, wenn sie entsprechend ausgeführt bzw. angeordnet sind.It is also particularly advantageous if the device has one or more guide elements which are arranged and / or adjustable such that the two weft materials are guided at least at the output, so when removing from the device such that a line of symmetry, halfway Width of the first weft material perpendicular to the surface thereof, lies in a plane with a line of symmetry, which extends at half the width of the second weft material perpendicular to the surface thereof. This means that the two symmetry lines of the two weft materials lie in one plane. As a result, the low-deflection feed to a weft insertion element of a weaving machine is further promoted.
Also for this purpose, existing or additional elements or the side walls of the interior can serve as guide elements, if they are designed or arranged accordingly.
In Verbindung mit angetriebenen Vorratsspulen für das Schussmaterial ergibt sich eine einfach aufgebaute, symmetrische Anordnung der Vorrichtung zum Beispiel dann, wenn die Drehachsen, um die die beiden Vorratsspulen jeweils antreibbar sind, derartig angeordnet sind, dass die Ebenen, in denen die Schmalseiten der beiden Innenräume verlaufen, zwischen den Drehachsen liegen. Das bedeutet, dass die Speicherbehälter zum Beispiel mittig im Zwischenraum zwischen den Drehachsen der beiden Vorratspulen liegen. Es sind jedoch auch andere, auch unsymmetrische Anordnungen der Drehachsen denkbar (z.B. vor oder hinter, über oder unter den Speicherbehältern), die dann allerdings zusätzliche Umlenkungen erforderlich machen können.
Es ist dabei zweckmäßig, wenn sich die Schmalseiten der Innenräume der Speicherbehälter in ihrer Breitenausdehnung parallel zur Richtung der Drehachsen der Vorratsspulen erstrecken, da dann zwischen Vorratsspulen und Innenräumen ein verdrehungsfreier Lauf des Schussmaterials möglich ist.In conjunction with driven supply spools for the weft material results in a simple structure, symmetrical arrangement of the device, for example, when the axes of rotation about which the two supply spools are each driven, are arranged such that the planes in which the narrow sides of the two interiors run, lie between the axes of rotation. This means that the storage containers, for example, are located centrally in the intermediate space between the axes of rotation of the two supply reels. However, other asymmetrical arrangements of the axes of rotation are also conceivable (for example, in front of or behind, above or below the storage containers), which, however, may then necessitate additional deflections.
It is expedient if the narrow sides of the interiors of the storage container in its width extension extend parallel to the direction of the axes of rotation of the supply reels, since then between supply reels and interiors a torsion-free running of the weft material is possible.
Besonders vorteilhaft ist eine Anordnung von Speicherbehältern und Umlenkelementen, die zum Teil oder vollständig spiegelbildlich zu einer in Längsrichtung weisenden, in der Mitte zwischen den beiden Speicherbehältern liegenden Mittellinie aufgebaut ist. Dieser spiegelbildliche Aufbau ermöglicht, die beiden Schussmaterialien in der Nähe der Mittellinie aus der Vorrichtung abzuführen und einer Webmaschine zuzuführen, ohne dass weitere Umlenkungen der Schussmaterialien auftreten.
Bei dieser Anordnung ergibt sich, dass alle vier Schmalseiten der beiden Innenräume in parallel zueinander verlaufenden Ebenen liegen.Particularly advantageous is an arrangement of storage containers and deflecting elements, which is constructed partly or completely mirror-inverted to a longitudinally oriented, lying in the middle between the two storage tanks center line. This mirror-image construction makes it possible to remove the two weft materials in the vicinity of the center line from the device and feed them to a weaving machine without further deflections of the weft materials occurring.
With this arrangement, it follows that all four narrow sides of the two inner spaces lie in mutually parallel planes.
Konstruktiv vorteilhaft ist es weiterhin, die Vorrichtung so auszuführen, dass eine Trennwand zwischen den beiden Innenräumen vorhanden ist, die beiden Speicherbehältern gemeinsam ist. Diese Trennwand enthält damit die oben beschriebene Mittellinie der beiden Speicherbehälter. Eine solche Anordnung ergibt geringste Umlenkungen und ist besonders platzsparend.
Die Speicherbehälter können zum Beispiel als Speicherschächte mit Öffnungen für das Schussmaterial an jeweils einem der Schachtenden ausgeführt sein. Vorteilhaft ist es dabei, wenn die Öffnungen der beiden Speicherschächte in einer Ebene liegen.
Die Vorrichtung kann weiterhin mit einer Unterdruckeinrichtung zum Ausüben der Zugkräfte auf die beiden Schussmaterialien ausgestattet sein. Die Unterdruckeinrichtung ist dabei zum Beispiel so ausgeführt, dass damit wahlweise im ersten oder im zweiten oder in beiden Speicherbehältern ein Unterdruck erzeugt werden kann. Dazu wird eine Umschalteinrichtung eingesetzt.
Auf diese Weise ist es möglich, im Betrieb mit einer einzigen Unterdruckeinrichtung - zum Beispiel eine Vakuumpumpe - beide Speicherbehälter abwechselnd oder gleichzeitig mit Unterdruck zu beaufschlagen. Bei Wartungsarbeiten an einem der Speicherbehälter kann außerdem durch die Umschaltmöglichkeit dieser Speicherbehälter vom Unterdrucksystem getrennt werden.
Denkbar ist jedoch auch die Verwendung je einer Unterdruckeinrichtung für je einen Speicherbehälter, wobei auch damit die oben beschriebene abwechselnde Betriebsweise und evt. auch unterschiedliche Unterdrücke in den beiden Speicherbehältern möglich sind.It is also structurally advantageous to design the device in such a way that there is a partition wall between the two interior spaces, which is common to the two storage containers. This partition thus contains the above-described center line of the two storage tanks. Such an arrangement results in the lowest deflections and is particularly space-saving.
The storage containers may be designed, for example, as storage shafts with openings for the weft material at in each case one of the shaft ends. Advantageous It is there, if the openings of the two storage shafts lie in one plane.
The device may further be equipped with a vacuum device for exerting the tensile forces on the two weft materials. The negative-pressure device is designed, for example, so that a negative pressure can be generated either in the first or in the second or in both storage containers. For this purpose, a switching device is used.
In this way, it is possible, during operation with a single vacuum device - for example a vacuum pump - to pressurize both storage tanks alternately or simultaneously with negative pressure. During maintenance work on one of the storage container can also be separated from the vacuum system by the switchover of this storage container.
However, it is also conceivable to use one negative pressure device for each one storage container, with which also the above-described alternating operation and possibly also different negative pressures in the two storage containers are possible.
Alternativ zur Unterdruckeinrichtung kann jedoch die Zugkraft auch durch eine Federeinrichtung ausgeübt werden, die über ein bewegliches Umlenkelement eine Zugkraft auf das Schussmaterial ausübt. Dabei ist das eine Ende einer Feder mit dem Speicherbehälter und das andere mit dem beweglichen Umlenkelement verbunden.Alternatively to the vacuum device, however, the tensile force can also be exerted by a spring device which exerts a pulling force on the weft material via a movable deflection element. In this case, one end of a spring is connected to the storage container and the other to the movable deflecting element.
Besonders vorteilhaft ist es, an einer Webmaschine die beiden Speicherbehälter der Vorrichtung zum Zwischenspeichern der beiden bandartigen Schussmaterialien derartig anzuordnen, dass die beiden Zugkräfte parallel zu einer Schussrichtung der Webmaschine verlaufen. Das Schussmaterial kann somit vom Speicherbehälter bis zum Schusseintragselement ohne eine Umlenkung um 90 Grad zugeführt werden.It is particularly advantageous to arrange the two storage containers of the device for temporarily storing the two ribbon-like weft materials on a weaving machine in such a way that the two pulling forces run parallel to a weft direction of the weaving machine. The weft material can thus be supplied from the storage container to the weft insertion element without a deflection by 90 degrees.
Es können außerdem die beiden Innenräume der Speicherbehälter symmetrisch zu einer Linie angeordnet sein, die im Wesentlichen in der Verlängerung einer Bewegungslinie eines Schusseintragselementes der Webmaschine verläuft.It can also be arranged symmetrically to a line which extends substantially in the extension of a line of movement of a weft insertion member of the loom, the two interiors of the storage container.
Damit wird erreicht, dass beide Schussmaterialien ausgehend von den jeweiligen Speicherbehältern um den jeweils gleichen Betrag ausgelenkt werden müssen, um in die Bewegungslinie des Schusseintragselements zu gelangen.This ensures that both shot materials must be deflected starting from the respective storage containers by the same amount in each case in order to reach the line of movement of the weft insertion element.
Für die Verarbeitung von zwei bandartigen Schussmaterialien, die im Wechsel an der Webmaschine eingetragen werden sollen, ist es besonders vorteilhaft, wenn an der Webmaschine mit der Vorrichtung zum Zwischenspeichern der beiden bandartigen Schussmaterialien außerdem eine Auswahlvorrichtung vorgesehen ist, die zwischen den Öffnungen der beiden Speicherbehälter für die beiden Schussmaterialien und dem Eingang eines Webfachs der Webmaschine angeordnet ist und mit der wahlweise das erste oder das zweite Schussmaterial dem Schusseintragselement der Webmaschine zuführbar ist.For the processing of two ribbon-like weft materials to be registered alternately on the loom, it is particularly advantageous if the loom with the device for temporary storage of the two ribbon-like weft materials also a selection device is provided which between the openings of the two storage tanks for the two weft materials and the entrance of a shed of the weaving machine is arranged and with which either the first or the second weft material can be fed to the weft insertion element of the weaving machine.

Die
Das erste bandartige Schussmaterial 1 wird über eine erste fest montierte Umlenkrolle 16, die als Umlenkelement arbeitet, einem schachtartigen ersten Speicherbehälter 7 mit einer Öffnung 8 an einem der Schachtenden zugeleitet. Wie im Stand der Technik üblich, wird dabei das erste Schussmaterial 1 von einer ersten Vorratsspule 5 abgezogen, die um eine Drehachse 6 drehbar angeordnet ist. Mit Hilfe einer ersten Antriebseinrichtung 4 kann die erste Vorratsspule 5 in bekannter Art und Weise um ihre Drehachse 6 angetrieben werden. Die Regelung bzw. Steuerung der Antriebseinrichtung 4 erfolgt dabei mit Hilfe einer nicht dargestellten Steuerung.
Das erste Schussmaterial 1 bildet im Innenraum 9 des ersten Speicherbehälters 7 eine U-förmige Schlaufe 12, die im vorliegenden Ausführungsbeispiel um eine bewegliche Schlaufenrolle geführt wird. Von dieser beweglichen Schlaufenrolle aus wird das erste Schussmaterial 1 durch die Öffnung 8 des ersten Speicherbehälters 7 wieder nach außen in Richtung zur Webmaschine 3 geführt.
Der Innenraum 9 des ersten Speicherbehälters 7 wird von zwei Schmalseiten 10, 11 begrenzt, die einen Abstand voneinander haben, der ausreicht, dass darin die U-förmige Schlaufe 12 um die bewegliche Schlaufenrolle herum ausgebildet werden kann.
Im Stand der Technik sind auch Ausführungsformen ohne bewegliche Schlaufenrolle bekannt geworden, bei denen sich die U-förmige Schlaufe frei im Innenraum bildet. Dies hat jedoch bestimmte Nachteile, sodass darauf hier nicht weiter eingegangen werden soll.
Im vorliegenden Beispiel ist der Abstand der beiden Schmalseiten 10, 11 etwas größer als der Durchmesser der beweglichen Schlaufenrolle. Damit ist gewährleistet, dass sich diese bewegliche Schlaufenrolle in Längsrichtung 13 des Speicherbehälters 7 bewegen kann.
Die bewegliche Schlaufenrolle ist so breit, dass sie die U-förmige Schlaufe 12 des ersten bandartigen Schussmaterials 1 in seiner ganzen Breite aufnehmen und umlenken kann. Um auch eine seitliche Führung des bandartigen Schussmaterials 1 zu gewährleisten, ist im vorliegenden Beispiel die bewegliche Schlaufenrolle zusätzlich mit Borden 18 zur Führung der beiden Seitenkanten des bandartigen Schussmaterials 1 ausgestattet. Die Breite des Innenraums 9 ist etwas größer als die Breite der beweglichen Schlaufenrolle. Die beiden Seiten des Innenraums 9, die die Breite des Innenraums 9 begrenzen, werden durch Deckel verschlossen. Dies ist erforderlich, damit im Innenraum 9 ein Unterdruck aufgebaut werden kann, durch den auf das Schussmaterial 1 im Speicherbehälter 7 eine Zugkraft 15 ausgeübt wird.
Bei einer alternativen - nicht dargestellten - Ausführung der Vorrichtung, bei der die Zugkraft durch eine Federeinrichtung ausgeübt wird und nicht durch Unterdruck, sind die seitlichen Deckel eventuell verzichtbar.
Im vorliegenden Ausführungsbeispiel wird im Innenraum 9 des Speicherbehälters 7 ein Unterdruck durch eine Unterdruckeinrichtung 14 in Form einer Vakuumpumpe erzeugt. Dazu steht die Unterdruckeinrichtung 14 über eine Leitung und eine Ansaugöffnung mit dem Innenraum 9 in Verbindung. Die Ansaugöffnung ist vorliegend an dem Ende des schachtartigen Speicherbehälters 7 angeordnet, die der Öffnung 8 für das Schussmaterial 1 abgewandt ist; sie ist mit einem siebartigen Gitter verschlossen.
Durch den Unterdruck wird das Schussmaterial 1 mit der beweglichen Schlaufenrolle von der Öffnung 8 weg in den ersten Speicherbehälter 7 hinein gesaugt; es wird eine Zugkraft 15 auf das Schussmaterial ausgeübt.
Es ist üblich, die Antriebseinrichtung 4 für die erste Vorratspule 5 so zu steuern, dass die bewegliche Schlaufenrolle nur bis zu einer bestimmten Position eingesaugt werden kann. Diese Position wird in bekannter Art und Weise über entsprechende Sensoren am Speicherbehälter 7 ermittelt und an die Steuerung der ersten Antriebseinrichtung 4 weiter geleitet. Beim Abzug des Schussmaterials 1 aus dem Speicherbehälter 7 durch das Schusseintragselement 43 der Webmaschine 3 wird die bewegliche Schlaufenrolle in Richtung auf die Öffnung 8 des Speicherbehälters 7 gezogen und anschließend durch den Unterdruck und durch eine entsprechende Ansteuerung der Vorratsspule 5 wieder in die ursprüngliche Position im Speicherbehälter 7 gebracht. Derartige Vorrichtungen und die Verfahren zu ihrer Steuerung sind dem Fachmann bekannt und brauchen daher hier nicht weiter erläutert zu werden.The first belt-

Der Innenraum 29 des zweiten Speicherbehälters 27 wird analog zum Innenraum 9 des ersten Speicherbehälters 7 von zwei Schmalseiten 30, 31 und zwei Deckeln begrenzt, deren Abstände sich an den Abmessungen der U-förmigen Schlaufe 32 bzw. der beweglichen Schlaufenrolle orientieren.
Die Abmessungen der zweiten beweglichen Schlaufenrolle sind in Bezug auf das zweite Schussmaterial 21 unter den gleichen Gesichtspunkten gewählt, wie bei der ersten beweglichen Schlaufenrolle für das erste Schussmaterial 1. Analog zu den Borden 18 der ersten Schlaufenrolle sind Borde 38 an der zweiten Schlaufenrolle angebracht.
Auf das zweite bandartige Schussmaterial 21 wird im zweiten Speicherbehälter 27 eine Zugkraft 35 ausgeübt. Dies geschieht im vorliegenden Fall durch die gleiche Unterdruckeinrichtung 14, die auch für den Unterdruck im ersten Speicherbehälter 7 sorgt. Durch eine nicht dargestellte Umschalteinrichtung kann die Unterdruckeinrichtung 14 wahlweise mit der Ansaugöffnung des ersten oder des zweiten Speicherbehälters 7, 27 oder gleichzeitig mit beiden Ansaugöffnungen Druck übertragend in Verbindung gebracht werden. Denkbar ist natürlich auch, eine separate zweite Unterdruckeinrichtung 34 für den zweiten Speicherbehälter 7 vorzusehen. Durch den Unterdruck wird auch das zweite Schussmaterial 21 mit der beweglichen Schlaufenrolle von der Öffnung 28 weg in den zweiten Speicherbehälter 27 hinein gesaugt.
Die Positionssteuerung der zweiten U-förmigen Schlaufe 32 bzw. der zweiten beweglichen Schlaufenrolle beim Abzug des zweiten Schussmaterials 21 durch die Webmaschine 3 erfolgt analog zur Positionssteuerung im ersten Speicherbehälter 7 mit Hilfe entsprechender - nicht dargestellter - Sensoren am zweiten Speicherbehälter 27 sowie durch die Steuerung der Antriebseinrichtung 24 für die zweite Vorratspule 25.The interior 29 of the

Im vorliegenden Ausführungsbeispiel ist die Vorrichtung mit einer Trennwand 20 zwischen den beiden Speicherbehältern 7, 27 ausgestattet. Diese Trennwand 20 bildet mit zwei von ihren Längsseiten die beiden Schmalseiten 10, 30, die jeweils einen der beiden Innenräume 9, 29 der Speicherbehälter 7, 27 begrenzen. Die Schmalseiten 10, 11, 30, 31 verlaufen in Ebenen, die parallel zueinander sind.
Die beiden Umlenkelemente 16, 36 - vorliegend als fest am jeweiligen Speicherbehälter 7,27 montierte Umlenkrollen ausgebildet - sind so angeordnet, dass das jeweilige Schussmaterial 1, 21 dem zugehörigen Speicherbehälter 7, 27 in Bezug zu den Schmalseiten 10, 11, 30, 31 in einem Bereich 17, 37 des betreffenden Innenraums 9, 29 zugeführt wird, der jeweils näher an derjenigen Schmalseite 11, 31 liegt, die dem jeweils anderen Speicherbehälter 7, 27 abgewandt ist. Auch die zugehörigen Vorratsspulen 5, 25 und Antriebseinrichtungen 4, 24 sind im vorliegenden Beispiel auf der Seite des jeweiligen Speicherbehälters 7, 27 angeordnet, die dem jeweils anderen Speicherbehälter 7, 27 abgewandt ist. Wie bereits oben erläutert, sind jedoch auch andere Positionen der Vorratsspulen 5, 25 denkbar. Im vorliegenden Beispiel ergibt sich eine spiegelbildliche Anordnung der Speicherbehälter 7, 27 mit ihren Innenräumen 9, 29 sowie den Vorratsspulen 5, 25 und Umlenkelementen 16, 36, wobei die Ebenen, in denen die Schmalseiten 10,11, 30, 31 der Innenräume 9, 29 verlaufen, zwischen den Drehachsen 6, 26 der beiden Vorratspulen 5, 25 liegen. Dabei ist es vorteilhaft, wenn diese beiden Drehachsen 6, 26 parallel zu den Ebenen der Schmalseiten 10, 11, 30, 31 der Innenräume 9, 29 verlaufen, sodass keine Verdrehungen des Schussmaterials 1, 21 auftreten können.The

Die Vorrichtung weist eine Mittellinie 41 oder Spiegellinie auf, die in Längsrichtung 13, 33 der Speicherbehälter 7, 27 in der Mitte zwischen den beiden einander zugewandten Schmalseiten 10, 30 der Innenräume 9, 29 verläuft. Im vorliegenden Ausführungsbeispiel liegt diese Mittellinie 41 innerhalb der Trennwand 20 zwischen den beiden Innenräumen 9, 29 auf halber Breite des zugeführten bandartigen Schussmaterials 1,21 bzw. auf halber Breite der beiden Innenräume 9, 29.
Die beschriebene spiegelbildliche Anordnung gewährleistet, dass beide Schussmaterialien 1, 21 ohne wesentliche weitere Umlenkungen in Richtung auf eine Webmaschine 3 hingeführt werden können. Eine besonders kompakte Ausführung ergibt sich durch die Integration der beiden Speicherbehälter 7, 27 in einem Gehäuse mit einer gemeinsamen Trennwand 20 und mit einer Anordnung der Öffnungen 8, 28 für das Schussmaterial 1, 21 in einer Ebene am einen Ende der schachtartigen Speicherbehälter 7, 27 (vgl.
The described mirror-image arrangement ensures that both
Im vorliegenden Ausführungsbeispiel wird die umlenkungsfreie Zuführung des Schussmaterials 1, 21 noch dadurch unterstützt, dass die beiden Schussmaterialien 1,21 derartig geführt werden, dass ihre Oberflächen 19, 39 parallel zueinander und übereinander verlaufen (
Die Vorrichtung ist jedoch auch einsetzbar an Webmaschinen, bei denen die Kettfäden vertikal und die Schussfäden horizontal verlaufen. Diese Anordnung ist hier nicht in Figuren dargestellt. Die Breite des Schussmaterials erstreckt sich in so einem Fall ebenfalls in Richtung der Kettfäden - somit also vertikal. Demnach verlaufen auch die Drehachsen der beiden Vorratsspulen in diesem Fall am zweckmäßigsten vertikal und die Speicherbehälter sind horizontal nebeneinander angeordnet.In the present exemplary embodiment, the deflection-free feeding of the
However, the device can also be used on looms in which the warp threads are vertical and the weft threads are horizontal. This arrangement is not shown here in figures. The width of the weft material also extends in such a case in the direction of the warp threads - thus vertically. Accordingly, the axes of rotation of the two supply spools also run most expediently vertically in this case, and the storage containers are arranged horizontally next to one another.
Die Führung der beiden Schussmaterialien 1,21 erfolgt zu diesem Zweck durch Führungselemente 18, 38 an der Vorrichtung, die das bandartige Schussmaterial 1, 21 in Richtung seiner Breite und/oder in Richtung seiner Dicke führen.
Im vorliegenden Beispiel sind zu diesem Zweck separate Führungselemente 18, 38 an den beiden Speicherbehältern 7, 27 im Bereich der Öffnungen 8, 28 für das jeweilige Schussmaterial 1, 21 angebracht. Diese Führungselemente 18, 38 sind so angeordnet, dass die beschriebene Art der Führung gewährleistet ist. Diese Führung kann aber auch durch entsprechende Gestaltung der Umlenkelemente 16, 36 und/oder durch Borde 18, 38 an den bewegliche Schlaufenrollen erfolgen.
Um verschiedene Breiten von Schussmaterial 1, 21 führen zu können und um Toleranzen der Bauteile ausgleichen zu können, ist es weiterhin vorteilhaft, wenn die Führungselemente 18, 38 so einstellbar sind, dass die oben beschriebene Art der Führung optimiert werden kann.
Dabei ist die Anbringung bzw. Einstellung der Führungselemente 18, 38 am vorteilhaftesten derartig, dass das jeweilige Schussmaterial 1, 21 aus dem zugehörigen Speicherbehälter 7, 27 in Bezug zu den Schmalseiten 10, 11, 30, 31 aus einem Bereich des betreffenden Innenraums 9, 29 abgeführt wird, der jeweils näher an derjenigen Schmalseite 10, 30 liegt, die dem jeweils anderen Speicherbehälter 7, 27 zugewandt ist.
