Description

Die Erfindung betrifft eine Vorrichtung an einer Karde zum Füllen einer Rundkanne mit Faserband, z. B. Baumwolle, Chemiefasern o. dgl., bei der das Faserband von einem drehbaren Ablagekopf abgebbar und in Ringen in der Rundkanne ablegbar ist, wobei während des Füllvorganges der Ablagekopf oberhalb der Rundkanne angeordnet ist und die Rundkanne ortsfest auf einem drehbaren Kannenteller um eine senkrechte Achse rotiert, und bei der nach Füllung einer Vollkanne und vor Füllung einer Leerkanne die örtliche Zuordnung zwischen dem Ablagekopf einerseits und der Vollkanne und der Leerkanne andererseits wechselt (Kannenwechsel), und eine Vollkanne abförderbar und eine Leerkanne zuführbar ist (Kannenaustausch).The invention relates to a device on a card for filling a round can with sliver, for. B. cotton, man-made fibers or the like, in which the sliver can be dispensed from a rotatable depositing head and deposited in rings in the round can, during the filling process the depositing head is arranged above the round can and the round can is fixed on a rotatable can plate around a vertical one Axis rotates, and in the case of filling a full can and before filling an empty can, the local assignment between the storage head on the one hand and the full can and the empty can on the other changes (can change), and a full can can be removed and an empty can can be fed (can replacement).

Zum Wechsel von Rundkannen an einer Karde sind Rotationskannenwechsler ( US 4208768 ) und Linearkannenwechsler ( EP 967169 B ) bekannt. Diese Kannenwechsler sind grundsätzlich so aufgebaut, dass mindestens drei mögliche Kannenpositionen vorgehalten werden:

  1. 1. Leer- oder Reserve-Position
  2. 2. Füllposition
  3. 3. Vollkannenposition
Rotation can changers are used to change round cans on a card ( US 4208768 ) and linear can changer ( EP 967169 B ) known. These can changers are basically designed so that at least three possible can positions are available:
  1. 1. Empty or reserve position
  2. 2. Filling position
  3. 3. Full can position

Beim Kannenwechsel werden die Rundkannen bewegt und wechseln die Positionen. Dazu muss in der Regel die Ablagegeschwindigkeit reduziert werden, da ansonsten Fasermaterial zwischen die Rundkannen gefördert wird. Wünschenswert aus Kundensicht ist jedoch ein schneller Wechsel der Rundkannen, damit die Produktion der Karde nicht nennenswert reduziert werden muss. Desweiteren treten bei großen Veränderungen der Liefergeschwindigkeit Schwankungen des Bandgewichtes auf, welche das technologische Ergebnis bis hin zum Endprodukt negativ beeinflussen können. Ein schneller Wechsel der Rundkannen ist jedoch mit verschiedenen Schwierigkeiten verbunden. Die Rundkannen haben keine durchgehend stabile Struktur und können daher durch hohe Kräfte beschädigt werden. Zum anderen unterscheiden sich die Rundkannen von Kunde zu Kunde, was die Anpassung von Aufnahmen schwierig macht. Weiterhin haben im gefüllten Zustand die Rundkannen ein hohes Gewicht, was bei kurzen Wechselzeiten während der Beschleunigung hohe Kräfte hervorruft.When changing cans, the round cans are moved and change positions. To do this, the depositing speed must generally be reduced, since otherwise fiber material is conveyed between the round cans. From the customer's point of view, however, a quick change of the round cans is desirable, so that the production of the card does not have to be significantly reduced. Furthermore, in the case of major changes, the Delivery speed fluctuations in the belt weight, which can negatively influence the technological result right down to the end product. A quick change of the round cans is associated with various difficulties. The round cans do not have a consistently stable structure and can therefore be damaged by high forces. On the other hand, the round cans differ from customer to customer, which makes the adaptation of recordings difficult. Furthermore, when filled, the round cans have a high weight, which causes high forces during short changeover times during acceleration.

Bei den bekannten Vorrichtungen bleibt der Drehteller (Ablagekopf) permanent ortsfest. Die Rundkannen werden unterhalb des Drehtellers verschoben, beim Rotationskannenwechsler auf einer Halbkreisbahn und beim Linearkannenwechsler auf einer Geraden. Mit Hilfe der Kannenwechsler sind eine in einer Reserveposition bereitgestellte leere Rundkanne zum Füllen mit Faserband in eine Füllposition unterhalb des Drehtellers und nach dem Füllen eine mit Faserband gefüllte Rundkanne in eine Abförderposition aus der Füllposition unterhalb des Drehtellers bringbar.In the known devices, the turntable (storage head) remains permanently stationary. The round cans are moved below the turntable, with the rotary can changer on a semicircular path and with the linear can changer on a straight line. With the help of the can changer, an empty round can provided in a reserve position for filling with sliver can be brought into a filling position below the turntable and, after filling, a round can filled with sliver can be brought into a discharge position from the filling position below the turntable.

In der US 2,571,880 wird ein Kannenwechsler mit einem verschwenkbaren Ablagekopf über zwei ortsfesten, aber drehbaren Kannentellern beschrieben. Bei einem Wechseln der Kanne verschwenkt der Ablagekopf von der vollen zur leeren Kanne, wobei mit der Schwenkbewegung gleichzeitig ein Antriebselement unterhalb des Kannentellers verschwenkt wird.In the US 2,571,880 describes a can changer with a swiveling storage head over two fixed but rotatable can plates. When changing the jug, the depositing head swivels from the full to the empty jug, with the pivoting movement simultaneously pivoting a drive element below the can plate.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere beim Kannenwechsel, d. h. beim Wechsel der örtlichen Zuordnung zwischen dem Ablagekopf einerseits und einer Vollkanne und einer Leerkanne andererseits, eine Bewegung der Rundkannen vermeidet, eine zeitliche Verkürzung des Kannenwechsels ermöglicht und eine einfache Verwirklichung des Kannentellerantriebs erlaubt.The invention is therefore based on the object to provide a device of the type described above, which avoids the disadvantages mentioned, in particular when changing the can, ie when changing the local assignment between the storage head on the one hand and a full can and an empty can on the other, a movement of the round cans avoids, the time required to change the can can be shortened and the can plate drive can be easily implemented.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of claim 1.

Dadurch, dass zum Kannenwechsel der Ablagekopf von einer Vollkanne zu einer Leerkanne örtlich verlagerbar, vorzugsweise verschiebbar ist, sowie zum Kannenaustausch bereits während der Füllung einer Leerkanne die Vollkanne abförderbar und eine neue Leerkanne zuführbar ist, sind die möglichen Kannenpositionen von drei Positionen auf zwei Positionen reduziert. Erfindungsgemäß werden nicht mehr - wie bei den bekannten Vorrichtungen - die Rundkannen unter dem Ablagekopf, sondern es wird der Ablagekopf über den Rundkannen verschoben. Im Gegensatz zu der bekannten Verlagerung der Rundkannen werden durch die Verlagerung des Ablagekopfes hohe Beschleunigungen des Ablagekopfes und damit geringe Wechselzeiten erreicht. Namentlich die Vollkannen können bei den bekannten Vorrichtungen aufgrund ihres hohen Gewichts nur mit hohen Kräften und nicht in kurzer Zeit bewegt werden. Der Bediener entnimmt die Vollkannen und ersetzt sie durch eine Leerkanne, so dass nur noch zwei Kannenpositionen vorgehalten werden müssen. Der Platzbedarf der erfindungsgemäßen Vorrichtung ist deutlich geringer als derjenige der bekannten Vorrichtungen. Insbesondere im Hinblick auf stetig steigende Kardenproduktionen ist mit einer Vergrößerung des Kannendurchmessers zu rechnen, was dann mit der erfindungsgemäßen Vorrichtung möglich ist, ohne den Kardenabstand vergrößern zu müssen. Ein weiterer Vorteil besteht darin, dass zwei Kannenteller für jeweils eine Vollkanne und eine Leerkanne vorhanden sind, die nur eine Antriebsvorrichtung für den Drehantrieb der beiden Kannenteller aufweist. Dadurch ist ermöglicht, dass nur die in der Füllposition befindliche Rundkanne rotiert, während die Rundkanne außerhalb der Füllposition nicht rotiert. Die Rundkanne außerhalb der Füllposition kann eine Vollkanne zur Abförderung oder eine Leerkanne zur Zuförderung sein. Der besondere Vorteil besteht darin, dass sowohl die Vollkannen als auch die Leerkannen ohne Problem von dem bzw. auf den nicht rotierenden Kannenteller gefördert werden können.The fact that the storage head can be moved from a full can to an empty can to be replaced, preferably moved, and that the full can can be removed and a new empty can be fed in while an empty can is being filled, and the new can can be fed, the possible can positions are reduced from three positions to two positions . According to the invention, the round cans are no longer - as in the known devices - under the storage head, but the storage head is moved over the round cans. In contrast to the known displacement of the round cans, the displacement of the depositing head achieves high accelerations of the depositing head and thus short changeover times. In particular, the full cans can only be moved with high forces and not in a short time in the known devices because of their high weight. The operator removes the full cans and replaces them with an empty can, so that only two can positions have to be kept. The space requirement of the device according to the invention is significantly less than that of the known devices. In particular with regard to steadily increasing card production, an increase in the can diameter can be expected, which is then possible with the device according to the invention without having to increase the card spacing. Another advantage is that there are two can plates, each for a full can and an empty can, which has only one drive device for the rotary drive of the two can plates. This makes it possible that only the round can located in the filling position rotates, while the round can outside Filling position not rotated. The round jug outside the filling position can be a full jug for removal or an empty jug for feeding. The particular advantage is that both the full cans and the empty cans can be conveyed from or onto the non-rotating can plate without any problem.

Die Drehrichtungen der Walzen sind mit gebogenen Pfeilen gezeigt. Mit M ist der Mittelpunkt (Achse) der Trommel 4 bezeichnet. 4a gibt die Garnitur und 4b gibt die Drehrichtung der Trommel 4 an. Der Pfeil A bezeichnet die Arbeitsrichtung der Karde K. Der Karde K ist eine Flockenspeiservorrichtung 17 vorgelagert. In der Ablagetellerplatte 18 ist der Ablagekopf 19 drehbar gelagert. Der Ablagekopf 19 umfasst einen Bandkanal 20 mit einem Einlauf und einem Auslauf für Faserband und einen Drehteller 21, an dessen Unterseite eine Abdeckung vorhanden ist. Bei gleichzeitiger Drehung der Kanne 15I wird das Faserband 14 zykloidenförmig in der Kanne 15I abgelegt, wodurch eine gleichmäßige Füllung der Kanne 15I mit Faserband möglich ist. Nach Fig. 1 wird eine Leerkanne 15I mit Faserband gefüllt, während eine Vollkanne 15" mit Faserband abgefördert wird (vgl. Fig. 5c). Fig. 1 shows a card K, z. B. Trützschler card TC, with feed roller 1, dining table 2, licker-in 3a, 3b, 3c, drum 4, taker 5, doctor roller 6, pinch rollers 7, 8, fleece guide element 9, pile funnel 10, take-off rollers 11, 12, revolving cover 13 with cover deflection rollers and Flat bars, jugs 15 I , 15 II and jug stick 16. The directions of rotation of the rollers are shown with curved arrows. M is the center (axis) of the drum 4. 4a indicates the clothing and 4b indicates the direction of rotation of the drum 4. The arrow A denotes the working direction of the card K. The card K is upstream of a flake feed device 17. The storage head 19 is rotatably mounted in the storage plate plate 18. The storage head 19 comprises a belt channel 20 with an inlet and an outlet for fiber sliver and a turntable 21, on the underside of which there is a cover. When the can 15 I is rotated at the same time, the sliver 14 is deposited in the can 15 I in a cycloidal manner, whereby a uniform filling of the can 15 I with sliver is possible. To Fig. 1 an empty can is filled with 15 I sliver while a full can is conveyed away 15 "with fiber tape (see FIG. Fig. 5c ).

Der Ablagekopf 19 ist einem verschiebbaren Gehäuse 22 (sh. Fig. 4) angeordnet. Vor dem Ablagekopf 19 sind zwei vorgelagerte Abzugswalzen 23a, 23b mit Bandtrichter 24 angeordnet, die in dem gemeinsamen Gehäuse 22 angeordnet sind.The storage head 19 is a displaceable housing 22 (see FIG. Fig. 4 ) arranged. In front of the depositing head 19, two upstream take-off rollers 23a, 23b with a band funnel 24 are arranged, which are arranged in the common housing 22.

Zwischen der Bandumlenkrolle 32 und dem Bandtrichter 24 kann ein Kardenstreckwerk 35 vorhanden sein, das entsprechend Fig. 1a in dem Gehäuse 22 angeordnet ist. Das Kardenstreckwerk 35 kann auch (nicht dargestellt) ortsfest dem verschiebbaren Gehäuse 22 vorgelagert sein.Between the belt deflection roller 32 and the belt funnel 24, a card drafting device 35 can be present, which accordingly Fig. 1a by doing Housing 22 is arranged. The card drafting unit 35 can also (not shown) be positioned upstream of the displaceable housing 22.

Die Vorrichtung zum Füllen von Rundkannen 152, 153 mit Faserband 14 weist nach Fig. 2 einen aus einer Trägerkonstruktion bestehenden Grundrahmen 25 auf. Die Höhe der oberen Tragstangen ist größer als die Höhe der Rundkannen 152, 153 die auf jeweils einem Kannenstellplatz 26a bzw. 26b angeordnet sind. Jeder Kannenstellplatz 26a bzw. 26b weist einen in Fig. 2a dargestellten in Richtung der Pfeile E, F rotierbaren Kannendrehteller 27a, 27b (an sich bekannt) auf, auf denen die Kannen 152 bzw. 153 langsam in einer Richtung drehbar angeordnet sind. Zwischen den oberen Tragstangen sind parallel zur Ebene durch die Mittelpunkte der Kannen 152 und 153 zwei Führungsmittel 28a und 28b eines Hilfsrahmens 29 gelagert, auf denen im dargestellten Ausführungsbeispiel der Hilfsrahmen 29 verschiebbar gelagert ist. Das Gehäuse 22 (sh. Fig. 4) enthält den mit dem Bandkanal 20 versehenen Drehteller 21 des Ablagekopfes 19. Der gebogene Pfeil zeigt die Drehrichtung des Drehtellers 21 an. Durch den Bandkanal 20 verläuft das Faserband 14, das von der Karde K (sh. Fig. 1) zugeführt wird. Der Drehteller 21 ist in bekannter Weise, z. B. durch einen (nicht dargestellten) Antriebsriemen mit einem (nicht dargestellten) Antriebsmechanismus verbunden.The device for filling round cans 15 2 , 15 3 with sliver 14 detects Fig. 2 a base frame 25 consisting of a support structure. The height of the upper support rods is greater than the height of the round cans 15 2 , 15 3, which are each arranged on a can parking space 26a or 26b. Each can position 26a or 26b has one in Fig. 2a shown in the direction of arrows E, F rotatable can turntable 27a, 27b (known per se) on which the cans 15 2 and 15 3 are slowly rotatable in one direction. Between the upper support rods parallel to the plane through the centers of the cans 15 2 and 15 3, two guide means 28a and 28b of an auxiliary frame 29 are mounted, on which the auxiliary frame 29 is slidably mounted in the illustrated embodiment. The housing 22 (see. Fig. 4 ) contains the turntable 21 of the storage head 19 provided with the band channel 20. The curved arrow indicates the direction of rotation of the turntable 21. The sliver 14 runs through the sliver channel 20 and is separated from the card K (see FIG. Fig. 1 ) is supplied. The turntable 21 is in a known manner, for. B. connected by a (not shown) drive belt with a (not shown) drive mechanism.

Dem Hilfsrahmen 29 ist eine Verstelleinrichtung zugeordnet, die im dargestellten Ausführungsbeispiel aus zwei doppeltwirkenden, am Grundrahmen 25 parallel zu den Führungsmitteln 28a, 28b gelagerten pneumatischen Zylindern 30a, 30b besteht. Die pneumatischen Zylinder 30a, 30b sind auf den gegenüberliegenden Seiten des Hilfsrahmens 29 angeordnet, und ihre Kolben sind mit diesem Hilfsrahmen 29 verbunden. Der Innenraum der pneumatischen Zylinder 30a, 30b ist auf bekannte Weise über eine nicht dargestellte Betätigungseinrichtung mit einer nicht dargestellten Quelle eines Druckmittels verbunden.The auxiliary frame 29 is assigned an adjustment device which, in the exemplary embodiment shown, consists of two double-acting pneumatic cylinders 30a, 30b mounted on the base frame 25 parallel to the guide means 28a, 28b. The pneumatic cylinders 30a, 30b are arranged on the opposite sides of the subframe 29, and their pistons are connected to this subframe 29. The interior of the pneumatic cylinders 30a, 30b is not known in a known manner Actuator shown connected to a source of pressure medium, not shown.

Das Faserband 14 wird aus einer das Faserband 14 produzierenden Maschine, z. B. aus einer Karde K, in bekannter Weise der Kannenablage zugeführt und dort in den Bandkanal 20 des sich drehenden Drehtellers 21 eingeführt. Gleichzeitig mit dem Drehen des Drehtellers 21 führt die Rundkanne 153 auf dem sich drehenden Kannenteller 27a eine Drehbewegung um ihre Rotationsachse aus, so dass das Faserband 14 in Zykloidenform abgelegt wird.The sliver 14 is from a sliver 14 producing machine, e.g. B. from a card K, the can tray in a known manner and introduced there into the band channel 20 of the rotating turntable 21. Simultaneously with the rotation of the turntable 21, the round can 15 3 executes a rotary movement about its axis of rotation on the rotating can plate 27a, so that the sliver 14 is deposited in a cycloid shape.

Sobald die unter dem Ablagekopf gelagerte runde Kanne 153 voll ist, setzt sich die Verstelleinrichtung des Hilfsrahmens 29 in Gang und verstellt sehr schnell den Hilfsrahmen 29 über die nächste leere runde Kanne 152, so dass der Ablagekopf ohne Stillsetzen des Drehtellers 21 und ohne Senkung seiner Drehgeschwindigkeit über die leere runde Kanne 152 zu liegen kommt, worauf das Faserband 14 unterbrochen wird, das ohne Senkung der Geschwindigkeit seiner Zufuhr durch den Bandkanal des Drehtellers 21 mit unveränderter Geschwindigkeit hindurchgeht und in die leere runde Kanne 152 abgelegt wird. Nach Füllung der Rundkanne 152 verschiebt die Verstelleinrichtung (Pneumatikzylinder 30a, 30b) den Hilfsrahmen 29 in Richtung der Pfeile, so dass der Drehteller 21 über eine neue Leerkanne zu liegen kommt.As soon as the round can 15 3 stored under the depositing head is full, the adjusting device of the auxiliary frame 29 starts and very quickly adjusts the auxiliary frame 29 over the next empty round can 15 2 , so that the depositing head without stopping the turntable 21 and without lowering its speed of rotation comes to lie over the empty round can 15 2 , whereupon the sliver 14 is interrupted, which passes through the band channel of the turntable 21 at unchanged speed without lowering the speed of its supply and is deposited in the empty round can 15 2 . After filling the round can 15 2, the adjusting device (pneumatic cylinder 30a, 30b) moves the auxiliary frame 29 in the direction of the arrows, so that the turntable 21 comes to rest on a new empty can.

Im dargestellten Ausführungsbeispiel besteht die Verstelleinrichtung des Hilfsrahmens 29 aus zwei doppeltwirkenden pneumatischen Zylindern 30a, 30b.In the exemplary embodiment shown, the adjusting device of the auxiliary frame 29 consists of two double-acting pneumatic cylinders 30a, 30b.

In Fig. 3 ist eine Draufsicht auf zwei Karden K1, K2 dargestellt, denen jeweils eine erfindungsgemäße Vorrichtung KW1, KW2 nachgeordnet ist. In den Vorrichtungen KW1 und KW2 sind jeweils eine Leerkanne 15I 1, 15II 1 bzw. eine Vollkanne 15I 2, 15II 2 dargestellt. Der Abstand zwischen den Karden K1 und K2 ist mit a bezeichnet und kann z. B. ca. 1300 bis 1400 mm betragen.In Fig. 3 a plan view of two cards K 1 , K 2 is shown, each of which is followed by a device KW 1 , KW 2 according to the invention. In the Devices KW 1 and KW 2 each show an empty jug 15 I 1 , 15 II 1 and a full jug 15 I 2 , 15 II 2 . The distance between the cards K 1 and K 2 is denoted by a and z. B. be about 1300 to 1400 mm.

Die gefüllten Pfeile zeigen die Richtung der Abförderung einer Vollkanne und die leeren Pfeile die Richtung der Zuführung einer Leerkanne von den bzw. zu den Vorrichtungen KW1 und KW2 an.The filled arrows indicate the direction of removal of a full can and the empty arrows indicate the direction of supply of an empty can from or to the devices KW 1 and KW 2 .

Entsprechend Fig. 4 weist das Faserband 14 zwischen dem Ausgang der Karde K (Abzugswalzen 11, 12, sh. Fig. 1) und einer ersten drehbaren Bandumlenkrolle 31 einen Bandabschnitt 14I, zwischen der Bandumlenkrolle 31 und einer zweiten Bandumlenkrolle 32 einen Bandabschnitt 14" und zwischen der Bandumlenkrolle 32 und der Durchtrittsöffnung in den Innenraum des Gehäuses 22 einen Bandabschnitt 14III auf. Der Bandabschnitt 14I weist die Form einer bogenförmig nach unten durchhängenden Bandschlaufe auf und bildet einen Bandspeicher. Zugleich erfolgt bei Verschiebung des Gehäuses 22 mit dem Ablagekopf 19 in Richtung der Pfeile B, C durch die Bandschlaufe 14I, d. h. die Bandspeichereinrichtung, ein Längenausgleich des Faserbandes 14I, ohne dass das Faserband 14 eine unerwünschte Verzugsänderung erfährt.Corresponding Fig. 4 has the sliver 14 between the output of the card K (take-off rollers 11, 12, sh. Fig. 1 ) and a first rotatable belt guide roller 31 a belt section 14 I , between the belt guide roller 31 and a second belt guide roller 32 a belt section 14 "and between the belt guide roller 32 and the passage opening into the interior of the housing 22 a belt section 14 III . The belt section 14 I the shape of an arched loop hanging downwards and forms a belt store.At the same time, when the housing 22 is moved with the storage head 19 in the direction of the arrows B, C by the belt loop 14 I , ie the belt storage device, a length compensation of the sliver 14 I takes place without that the sliver 14 experiences an undesirable change in distortion.

In den Fig. 5a bis 5e sind schematisch verschiedene Phasen des Kannenwechsels (örtlicher Wechsel des Ablagekopfes 19 von einer Vollkanne zu einer Leerkanne) und des Kannenaustausches (Zuführung einer Leerkanne und Abförderung einer Vollkanne) dargestellt.In the 5a to 5e Various phases of the can change (local change of the depositing head 19 from a full can to an empty can) and the can exchange (supply of an empty can and removal of a full can) are shown schematically.

Fig. 5a zeigt die Ausgangsposition, bei der unterhalb des Drehtellers 21 des Ablagekopfes 19 auf dem Kannenstellplatz 26a eine Leerkanne 151 angeordnet ist, während eine weitere Leerkanne 152 auf den Kannenstellplatz 26b in Richtung G zugeführt wird. Nach Fig. 5b ist die Kanne 153 (Vollkanne) auf dem Kannenstellplatz 26a mit Faserband 14 gefüllt, während auf dem Kannenstellplatz 26b die Leerkanne 152 vorhanden ist. Entsprechend Fig. 5c wird der Drehteller 21 in Richtung B horizontal über die Leerkanne 152 auf den Kannenstellplatz 26b verschoben, worauf die Vollkanne 153 vom Kannenstellplatz 26a in Richtung des Pfeils H abgefördert wird. Nach Fig. 5d ist die Kanne 154 (Vollkanne) auf dem Kannenstellplatz 26b gefüllt, während dem Kannenstellplatz 26a eine Leerkanne 155 in Richtung I zugeführt wird. Gemäß Fig. 5e wird der Drehteller 21 in Richtung C über die Leerkanne 155 verschoben, worauf die Vollkanne 154 in Richtung L abgefördert wird. Fig. 5a shows the starting position, in which an empty can 15 1 is arranged below the turntable 21 of the storage head 19 on the can parking space 26a, while another empty can 15 2 is fed to the can parking space 26b in the direction G. To Fig. 5b is the jug 15 3 (Full can) on the can space 26a filled with sliver 14, while the empty can 15 2 is present in the can space 26b. Corresponding Fig. 5c the turntable 21 is moved horizontally in the direction B over the empty can 15 2 to the can parking space 26b, whereupon the full can 15 3 is removed from the can space 26a in the direction of the arrow H. To Fig. 5d the can 15 4 (full can) on the can position 26b is filled, while the can position 26a is supplied with an empty can 15 5 in the direction I. According to Fig. 5e the turntable 21 is moved in the direction C over the empty can 15 5 , whereupon the full can 15 4 is conveyed in the direction L.

Ein wesentlicher Vorteil besteht darin, dass während der Füllung (sh. Fig. 5b, 5d) einer Vollkanne auf einem Kannenstellplatz unterhalb des Drehtellers, die eine gewisse Zeit in Anspruch nimmt, auf dem jeweils anderen Kannenstellplatz ohne Zeitdruck sowohl eine Vollkanne abgefördert als auch eine Leerkanne zugeführt werden kann (sh. Fig. 5c und 5d).A major advantage is that during the filling (see 5b, 5d ) a full can on a can space below the turntable, which takes a certain amount of time, both a full can and an empty can can be fed to the other can space without time pressure (see 5c and 5d ).

Ein besonderer weiterer Vorteil der erfindungsgemäßen Vorrichtung besteht darin, auf das Bewegen der Rundkannen während des Wechsels der Füllposition zu verzichten und gleichzeitig die möglichen Kannenpositionen von 3 auf 2 zu reduzieren. Erreicht wird dies durch einen verschiebbaren Ablagekopf. Das heißt, dass nicht mehr die Rundkannen unter dem Ablagekopf, sondern dieser über den Rundkannen verschoben wird. Hierzu wir der Kopf auf einer Linearführung gelagert und beim Wechsel durch einen Antrieb verschoben. Die Ausführung des Ablagekopfes kann so gewählt werden, dass hohe Beschleunigungen und damit geringe Wechselzeiten erreicht werden.A particular further advantage of the device according to the invention is that the circular cans do not have to be moved while the filling position is being changed and, at the same time, the possible can positions are reduced from 3 to 2. This is achieved by means of a sliding storage head. This means that it is no longer the round cans under the storage head, but this that is moved over the round cans. For this purpose, the head is mounted on a linear guide and moved by a drive when changing. The design of the storage head can be selected so that high accelerations and thus short changeover times are achieved.

Die Rundkannen rotieren beim Füllvorgang, um das typische Ablagebild (Zykloiden) zu erzeugen. Da nun zwei Füllpositionen vorhanden sind, müssen auch zwei Kannenteller für diese Rotationsbewegung vorgesehen werden. Der Antrieb der beiden Kannenteller kann jedoch mit einem Motor erfolgen, da dies unschädlich ist beim Austausch der vollen gegen eine leere Kanne. D. h. beide Kannenteller rotieren permanent.The round cans rotate during the filling process to create the typical deposit pattern (cycloids). Now that there are two fill positions, two can plates must also be provided for this rotational movement. However, the two can plates can be driven by a motor, as this is harmless when the full can is replaced by an empty can. That is, both can plates rotate continuously.

Der Bediener entnimmt bei dieser Anordnung die volle Rundkanne und ersetzt sie durch eine leere, was dazu führt, dass nur noch zwei Kannenpositionen vorgehalten werden müssen. Der Platzbedarf eines solchen Wechslers ist deutlicher geringer, als der herkömmliche Wechsler.With this arrangement, the operator removes the full round can and replaces it with an empty one, which means that only two can positions have to be kept. The space requirement of such a changer is significantly less than the conventional changer.

Insbesondere im Hinblick auf stetig steigende Kardenproduktionen ist mit einer Vergrößerung des Kannendurchmessers zu rechnen, was dann möglich ist, ohne den Kardenabstand a (sh. Fig. 3) vergrößern zu müssen.Especially with regard to steadily increasing card production, an increase in the can diameter is to be expected, which is then possible without the card spacing a (see Fig. 3 ) need to enlarge.

Fig. 6 zeigt in Vorderansicht die erfindungsgemäße Vorrichtung entsprechend Fig. 1. Der Ablagekopf 19 ist in Richtung der Pfeile B, C hin- und herverschiebbar angeordnet. In der Darstellung gemäß Fig. 6 befindet sich der Ablagekopf 19 oberhalb der Rundkanne 152, die mit ringförmig übereinander abgelegtem Faserband 14IV gefüllt wird. Mit 151 ist eine leere Rundkanne bezeichnet. Die Rundkannen 151 und 152 sind jeweils auf einem drehbaren Kannenteller 27a bzw. 27b angeordnet. Die Kannenteller 27a, 27b werden durch einen steuerbaren Antriebsmotor 43 angetrieben, dessen Drehrichtung in Richtung der Pfeile N, O umdrehbar ist. Mit 44a, 44b sind Riemenscheiben bezeichnet, die über Riemen 45a bzw. 45b mit der Welle des Antriebsmotors 43 verbunden sind. Fig. 6 shows the front view of the device according to the invention Fig. 1 . The storage head 19 is arranged so that it can be pushed back and forth in the direction of the arrows B, C. According to the representation Fig. 6 is the storage head 19 above the round can 15 2 , which is filled with sliver 14 IV laid in a ring on top of each other. With 15 1 an empty round jug is called. The round cans 15 1 and 15 2 are each arranged on a rotatable can plate 27a or 27b. The can plates 27a, 27b are driven by a controllable drive motor 43, the direction of rotation of which can be reversed in the direction of the arrows N, O. 44a, 44b denote pulleys which are connected to the shaft of the drive motor 43 via belts 45a and 45b, respectively.

Nach Fig. 7 ist eine elektronische Steuer- und Regeleinrichtung 36, z. B. Mikrocomputer, vorhanden, an die angeschlossen sind: eine Steuereinrichtung 37 für die Verlagerungseinrichtung 38 (z. B. Pneumatikzylinder 30a, 30b), ein Sensor 39 für die Füllung einer Vollkanne mit Faserband 14IV, eine Motorsteuereinrichtung 40 für den Antriebsmotor 41, z. B. Elektromotor, für den Ablagekopf 19 und eine Motorsteuereinrichtung 42 für den Antriebsmotor 43 für die Kannenteller 27a, 27b.To Fig. 7 is an electronic control and regulating device 36, z. B. microcomputer, to which are connected: a control device 37 for the displacement device 38 (z. B. pneumatic cylinder 30a, 30b), a sensor 39 for filling a full can with sliver 14 IV , one Motor control device 40 for the drive motor 41, e.g. B. electric motor, for the storage head 19 and a motor control device 42 for the drive motor 43 for the can plate 27a, 27b.

Entsprechend Fig. 8a ist ein Riementrieb als Antriebsmittel vorhanden. Ein Antriebsmotor 43 hat auf seiner Antriebswelle zwei Riemenräder 49a und 49b. Riemenrad 49a treibt den Riemen 45a für Kannenteller 27a an; Riemenrad 49b treibt den Riemen 45b für Kannenteller 27b an. Hierbei wird verhindert, dass die Antriebskraft auf Kannenteller 27a gelangt, wenn Kanne 152 gefüllt wird (sh. Fig. 6) und umgekehrt.Corresponding Fig. 8a there is a belt drive as a drive means. A drive motor 43 has two pulleys 49a and 49b on its drive shaft. Belt wheel 49a drives belt 45a for can plates 27a; Belt wheel 49b drives belt 45b for can plates 27b. This prevents the driving force from reaching the can plate 27a when the can 15 2 is filled (see Fig. 6 ) and vice versa.

Nach den in den Fig. 8a, 8b dargestellten Ausführungsform sind zwei Freiläufe 47a, 47b vorhanden. Ein Freilauf wird technisch im Stand der Technik durch ein Wälzlager realisiert, bei dem in einer Drehrichtung die Kugeln blockiert werden und somit ihre Kraftübertragung ermöglicht wird (sh. Fig. 8c). Der Freilauf 47a überträgt nur Kräfte der Drehung im Uhrzeigersinn.After the in the 8a, 8b In the embodiment shown, two freewheels 47a, 47b are present. Technically, a freewheel is implemented in the prior art by a roller bearing, in which the balls are blocked in one direction of rotation and thus their power transmission is made possible (see Fig. 8c ). The freewheel 47a only transmits clockwise rotation forces.

Durch die Funktion der Freiläufe 47a, 47b ergibt sich beispielsweise, dass der zentrale Antriebsmotor 43 zum Antrieb des Kannentellers 27b gegen den Uhrzeigersinn dreht. Zum Antrieb des Kannentellers 27a muss er im Uhrzeigersinn drehen.The function of the freewheels 47a, 47b results, for example, in that the central drive motor 43 rotates counterclockwise to drive the can plate 27b. To drive the can plate 27a, it must turn clockwise.

Zur Befüllung der Kanne müssen aber beide Kannenteller 27a, 27b in die gleiche Richtung drehen. In dem genannten Beispiel muss also eine Drehrichtungsumkehr realisiert werden. Bei der Verwendung eines Riemens ist die Drehrichtungsumkehr durch Kreuzen verwirklicht (sh. Fig. 9a, 9b).To fill the can, however, both can plates 27a, 27b must turn in the same direction. In the example mentioned, the direction of rotation must be reversed. When using a belt, the direction of rotation is reversed by crossing (see 9a, 9b ).

Bei einem Kugellagerfreilauf liegen die Kugeln in einem massiven Käfig, der entsprechend Fig. 8c gleichzeitig eine Anzahl einzeln angefederter Klemmkörper 48 führt. Die Klemmkörper 48 haben in Freilaufrichtung aufgrund ihrer geometrischen Form "abhebende Tendenz", die bei hohen Drehzahlen bis zur vollendeten Berührungsfreiheit zu den Ringen (Innenring 49 und Außenring 50) führt. Wichtig ist eine ausreichende relative Käfigdrehzahl aus genügender Radialbelastung des Lagers. Dieser Klemmkörperfreilauf arbeitet stufenlos und kraftschlüssig. Die Klemmkörper 48 heben in Freilaufrichtung (Vorlaufrichtung) aufgrund der Fliehkraft ab. In Rücklaufrichtung tritt eine Klemmwirkung und damit die Sperrwirkung aufgrund der Anpressung der Feder der Klemmkörper 48 gegen die Ringe 49, 50. Der Innenring 49 ist fest, z. B. als Presssitz, auf der Antriebswelle für die Riemenscheiben 44a, 44b angeordnet, wodurch die Sperrwirkung gegenüber der Antriebswelle eintritt. Der Außenring 50 dreht sich nicht.In a ball bearing freewheel, the balls lie in a solid cage, which corresponds accordingly Fig. 8c simultaneously leads a number of individually sprung clamping bodies 48. The sprags 48 have in the freewheeling direction their geometric shape "lifting tendency", which leads to the rings (inner ring 49 and outer ring 50) at high speeds up to complete freedom from contact. It is important to have a sufficient relative cage speed from a sufficient radial load on the bearing. This sprag freewheel works continuously and non-positively. The clamping bodies 48 lift off in the freewheeling direction (forward direction) due to the centrifugal force. In the return direction there is a clamping action and thus the locking action due to the pressure of the spring of the clamping body 48 against the rings 49, 50. The inner ring 49 is fixed, for. B. as a press fit, arranged on the drive shaft for the pulleys 44a, 44b, whereby the locking effect against the drive shaft occurs. The outer ring 50 does not rotate.

Die Erfindung ist am Beispiel eines Klemmkörperfreilaufs dargestellt, umfasst aber auch andere kraftschlüssige wirkende Freiläufe, z. B. Klemmrollenfreiläufe. Weiterhin umfasst die Erfindung sowohl ungelagerte Freiläufe, bei denen die Welle durch separate Lager, z. B. Wälzlager, gelagert ist als auch gelagerte Freiläufe (Kombination), bei denen der Freilauf und z. B. das Wälzlager (Kugellagert, Zylinderrolllager, Nadellager, Tonnenlager) ein integrales Bauteil bilden.The invention is illustrated using the example of a sprag freewheel, but also includes other non-positive freewheels, e.g. B. Pinch roller freewheels. Furthermore, the invention includes both unsupported freewheels in which the shaft by separate bearings, for. B. roller bearings, is also stored as freewheels (combination), in which the freewheel and z. B. the rolling bearing (ball bearings, cylindrical roller bearings, needle bearings, barrel bearings) form an integral component.

Die Fig. 9a, 9b zeigen die Drehrichtungsumkehr des Antriebsmotors 43 sowie der Antriebswelle zugeordneten ungekreuzten und gekreuzten Antriebsriemen.The 9a, 9b show the reversal of the direction of rotation of the drive motor 43 and the uncrossed and crossed drive belts assigned to the drive shaft.

Es gibt mehrere bekannte Prinzipien zur Drehrichtungsumkehr. Es kann zum Beispiel nach Fig. 10, 10a ein Getriebe 53 (z. B. Zahnräder 51, 52) vorgelegt werden.There are several known principles for reversing the direction of rotation. For example, it can be after 10, 10a a gear 53 (z. B. gears 51, 52) are presented.

Erfindungsgemäß ist eine wirtschaftliche Umsetzung des Kannentellerantriebes für eine Vorrichtung ermöglicht, bei der mit einem verschiebbaren Ablagekopf 19 zwei Kannenpositionen befüllt werden können.According to the invention, an economical implementation of the can plate drive is made possible for a device in which two can positions can be filled with a displaceable storage head 19.
