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, 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, z. As cotton, man-made fibers o. The like., In which the sliver off a rotatable storage head and can be stored in rings in the round pot, being arranged during the filling of the storage head above the round can, the round pot fixed on a rotatable can plate to a vertical Axis rotates, and in the after filling a full can and before filling a blank pot, the local assignment between the storage head on the one hand and the full and empty cans on the other hand changes (can change), and a full can be conveyed and an empty can be fed (Kannenaaustausch).

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
To change round cans on a card are rotary can changers ( US 4208768 ) and linear can changers ( EP 967169 B ) known. These can changers are basically designed to hold at least three possible can positions:
  1. 1. empty or reserve position
  2. 2nd 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 the can is changed, the round cans are moved and change positions. For this purpose, the filing speed must be reduced as a rule, since otherwise fiber material is conveyed between the round cans. However, from the customer's point of view, it is desirable to change the round cans quickly so that the production of the card does not have to be significantly reduced. Furthermore occur with large changes in delivery speed Variations in the weight of the band, which can adversely affect the technological result up to the end product. However, a quick change of the round cans is associated with various difficulties. The round cans have no 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, the round cans have a high weight in the filled state, which causes high forces during short change 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, the rotary can changer on a semicircular path and the Linearkannwechsler on a straight line. With the help of the can changer provided in a reserve position empty round can for filling with sliver in a filling position below the turntable and after filling a sliver filled with sliver can be brought into a discharge position from the filling position below the turntable.

Die US 2,571,880 offenbart eine Kannenfüllvorrichtung, bei der der Ablagekopf verschwenkbar über den Kannen angeordnet ist. Die Antriebsmechanik zum Verschwenken der Kannen wird mittels eines aufwändigen Getriebes realisiert.The US 2,571,880 discloses a can filling apparatus in which the tray head is pivotally mounted over the cans. The drive mechanism for pivoting the cans is realized by means of a complex transmission.

Die DE 10116944 A1 beschreibt eine Vorrichtung zum Füllen von Rechteckkannen, bei der der Ablagekopf rotiert, die Kanne unterhalb des Ablagekopfes linear verfahren wird. Der Ablagekopf kann seitlich von einer vollen Kanne zu einer leeren Kanne verfahren werden.The DE 10116944 A1 describes a device for filling rectangular cans, in which the storage head rotates, the jug is moved linearly below the storage head. The storage head can be moved laterally from a full pot to an empty pot.

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 und auf einfache Art eine zeitliche Verkürzung des Kannenwechsels ermöglicht.The invention is therefore based on the object to provide a device of the type described above, which avoids the disadvantages mentioned, in particular during the can change, d. H. when changing the local assignment between the storage head on the one hand and a full can and a dry can on the other hand, avoids a movement of the round cans and allows a simple way a shortening of the can change.

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

Dadurch, dass zum Kannenwechsel der Ablagekopf von einer Vollkanne zu einer Leerkanne verschiebbar gelagert 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.Characterized in that the can change the storage head is slidably mounted from a full pot to a empty can, as well as for can exchange during the filling of a empty can the Vollkanne ausförderbar and a new empty can be fed, the possible can positions of three positions are reduced to two positions. According to the invention are no longer - as in the known devices - the round cans under the storage head, but it is the storage head moved over the round cans. In contrast to the known displacement of the round cans high accelerations of the storage head and thus low changeover times are achieved by the displacement of the storage head. In particular, the full cans can be moved in the known devices due to their high weight only with high forces and not in a short time. The operator removes the full cans and replaces them with an empty can, so that only two can positions need to be reserved. The space requirement of the device according to the invention is significantly lower than that of the known devices. Especially with regard to steadily increasing card productions is to be expected with an increase in the can diameter, which then possible with the device according to the invention, without having to increase the card gap.

Der Pfeil A bezeichnet die Arbeitsrichtung der Karde K. Der Karde K ist eine Flockenspeiservorrichtung 17 vorgelagert. In einer Ablagetellerplatte 18 ist ein Ablagekopf 19 drehbar gelagert. Der Ablagekopf 19 umfasst einen Bandkanal 20 mit einem Einlauf und einem Auslauf für ein Faserband 14 und einen Drehteller 21, an dessen Unterseite eine Abdeckung vorhanden ist. Bei gleichzeitiger Drehung der Kanne 15' wird das Faserband 14 zykloidenförmig in der Kanne 15' abgelegt, wodurch eine gleichmäßige Füllung der Kanne 15' mit Faserband möglich ist. Nach Fig. 1 wird eine Leerkanne 15' mit Faserband gefüllt, während eine Vollkanne 15" mit Faserband abgefördert wird (vgl. Fig. 5c). Fig. 1 shows a card K, z. B. Trützschler carding machine TC, with feed roller 1, dining table 2, lickers 3a, 3b, 3c, drum 4, pickup 5, skimmer 6, nip rollers 7, 8, Vliesleitelement 9, trimming funnel 10, take-off rollers 11, 12, moving lid 13 with Deckelumlenkrollen and Flat bars, cans 15 ', 15 "and can stock 16. The directions of rotation of the rolls 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 carding machine K. The carding machine K is preceded by a flake feeding device 17. A storage head 19 is rotatably mounted in a storage tray plate 18. The storage head 19 comprises a belt channel 20 with an inlet and an outlet for a sliver 14 and a turntable 21 When the can 15 'is rotated simultaneously, the sliver 14 is deposited in the form of a cycloid in the can 15', whereby a uniform filling is achieved ung the pot 15 'with sliver is possible. To Fig. 1 becomes an empty can 15 'filled with sliver, while a full can 15 "is conveyed away with sliver (see. Fig. 5c ).

Der Ablagekopf 19 ist einem verschiebbaren Gehäuse 22 (sh. Fig. 1a) 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 sliding housing 22 (see. Fig. 1a ) arranged. Before the storage head 19, two upstream take-off rolls 23a, 23b are arranged with a belt hopper 24, which are arranged in the common housing 22.

Zwischen einer 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 a band deflection roller 32 and the belt hopper 24 may be present a Kardenstreckwerk 35, the corresponding Fig. 1a is disposed in the housing 22. The Kardenstreckwerk 35 may also be (not shown) stationary upstream of the sliding 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 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. 1a) enthält den mit dem Bandkanal 20 versehenen Drehteller 21 des Ablagekopfes 19. Der gebogene Pfeil D 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 points after 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 arranged on each one can tray 26a and 26b. Each can shelf 26a and 26b has an in Fig. 2a in the direction of the arrows E, F rotatable Kannendrehteller 27a, 27b (known per se), on which the cans 15 2 and 15 3 are arranged rotatably in one direction slowly rotatable in one direction. Between the upper support rods are parallel to the plane through centers of the cans 15 2 and 15 3 two guide means 28a and 28b of an auxiliary frame 29 mounted on which in the illustrated embodiment, the subframe 29 is slidably mounted. The housing 22 (see FIG. Fig. 1a ) Contains the provided with the band channel 20 turntable 21 of the storage head 19. The curved arrow D indicates the direction of rotation of the turntable 21 at. Through the band channel 20, the sliver 14, which extends from the card K (sh. Fig. 1 ) is supplied. The turntable 21 is in a known manner, for. By a (not shown) Drive belt connected to a drive mechanism (not shown).

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 subframe 29 is associated with an adjusting device which consists in the illustrated embodiment of two double-acting, on the base frame 25 parallel to the guide means 28a, 28b mounted pneumatic cylinders 30a, 30b. The pneumatic cylinders 30a, 30b are disposed on the opposite sides of the subframe 29, and their pistons are connected to this subframe 29. The interior of the pneumatic cylinder 30a, 30b is connected in a known manner via an actuating device, not shown, to a source, not shown, of a pressure medium.

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 made of a sliver 14 producing machine, for. B. from a card K, supplied in a known manner the can tray and introduced there in the band channel 20 of the rotating turntable 21. Simultaneously with the rotation of the turntable 21, the round can 15 3 executes on the rotating can plate 27 a a rotational movement about its axis of rotation, so that the sliver 14 is deposited in cycloid form.

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 B, C, so dass der Drehteller 21 über eine neue Leerkanne zu liegen kommt.Once the stored under the storage head round pot 15 3 is full, the adjustment of the subframe 29 is in motion and adjusted very quickly the subframe 29 on the next empty round pot 15 2 , so that the storage head without stopping the turntable 21 and without lowering its rotational speed over the empty round pot 15 2 comes to rest, whereupon the sliver 14 is interrupted, which passes without reducing the speed of its supply through the belt channel of the turntable 21 with unchanged speed and is stored in the empty round pot 15 2 . After filling the round pot 15 2 shifts the Adjustment device (pneumatic cylinder 30a, 30b) the subframe 29 in the direction of arrows B, C, so that the turntable 21 comes to rest on a new empty can.

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 151', 151" bzw. eine Vollkanne 152', 152" 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 is a plan view of two cards K 1 , K 2 shown, each of which a device according to the invention KW 1 , KW 2 is arranged downstream. In the devices KW 1 and KW 2 are each an empty can 15 1 ', 15 1 "and a full can 15 2 ', 15 2 " shown. The distance between the cards K 1 and K 2 is denoted by a and z. B. be about 1300 to 1400 mm.

Gefüllte Pfeile H1, H2, J1, J2 zeigen die Richtung der Abförderung einer Vollkanne an, und leere Pfeile G1, G1, I2, I2 die Richtung der Zuführung einer Leerkanne von den bzw. zu den Vorrichtungen KW1 und KW2.Filled arrows H 1 , H 2 , J 1 , J 2 indicate the direction of removal of a full can, and empty arrows G 1 , G 1 , I 2 , I 2 indicate the direction of feeding a blank 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 14', 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 14''' auf. Der Bandabschnitt 14' 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 14', d. h. die Bandspeichereinrichtung, ein Längenausgleich des Faserbandes 14', 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, see FIG. Fig. 1 1) and a first rotatable belt deflection roller 31 a belt section 14 ', between the belt pulley 31 and a second belt pulley 32 a belt section 14 "and between the belt pulley 32 and the passage opening in the interior of the housing 22 a belt section 14''' At the same time, when the housing 22 is moved with the storage head 19 in the direction of the arrows B, C through the belt loop 14 ', ie the belt storage device, length compensation of the sliver 14' takes place. Without the sliver 14 undergoing an undesirable distortion change.

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 Fig. 5a to 5e are schematically different phases of the can change (local change of the storage head 19 from a full can to a empty can) and the Kannenaustauschches (supply of a empty can and removal of a Vollkanne) represented.

Fig. 5a zeigt die Ausgangsposition, bei der unterhalb des Drehtellers 21 des hier nicht bezeichneten 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 15s verschoben, worauf die Vollkanne 154 in Richtung J abgefördert wird. Fig. 5a shows the starting position, in which below the turntable 21 of the storage head 19 not designated here on the can parking bay 26 a empty can 15 1 is arranged, while another empty can 15 2 is fed to the can parking bay 26 b in the direction G. To Fig. 5b is the pot 15 3 (full can) filled on the can parking bay 26a with sliver 14, while on the can parking bay 26b, the empty can 15 2 is present. Corresponding Fig. 5c the turntable 21 is moved in the direction B horizontally on the empty can 15 15 2 on the can parking bay 26, whereupon the full can 15 3 is conveyed away from the can parking bay 26 a in the direction of the arrow H. To Fig. 5d the pot is 15 4 (full can) filled in the can stand 26b during which can stand 26a an empty can is supplied in the direction of I 15. 5 According to Fig. 5e the turntable 21 is displaced in the direction C about the empty can 15s, after which the full can is conveyed away in the direction J 15. 4

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 significant advantage is that during the filling (see. Fig. 5b, 5d ) of a full can on a can parking space below the turntable, which takes a certain amount of time, on the other can pitch without time pressure both a full can be conveyed off as well as an empty can (see. Fig. 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 to dispense with the movement of the round cans during the change of the filling position and at the same time to reduce the possible can positions from 3 to 2. This is achieved by a movable storage head. This means that it is no longer the round cans under the storage head, but this is moved over the round cans. For this we the head mounted on a linear guide and moved when changing by a drive. The execution of the storage head can be chosen so that high accelerations and thus low 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 produce the typical storage image (cycloids). Since there are now two filling positions, two can plates must be provided for this rotation movement. However, the drive of the two can plates can be done with a motor, as this is harmless when replacing the full against an empty pot. Ie. both can plates rotate permanently.

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.In this arrangement, the operator removes the full round can and replaces it with an empty one, which means that only two can positions need to be reserved. The space requirement of such a changer is significantly lower 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.In particular, with regard to ever-increasing card productions is to be expected with an increase in the can diameter, which is then possible without the card gap a (sh. Fig. 3 ) 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 her verschiebbar 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 L, N umdrehbar ist. Mit 44a, 44b sind Riemenscheiben bezeichnet, die über Riemen 45a bzw. 45b mit der Welle 43a des Antriebsmotors 43 verbunden sind. Fig. 6 shows in front view of the device according to the invention accordingly Fig. 1 , The storage head 19 is arranged in the direction of arrows B, C back and forth. In the illustration according to Fig. 6 is the storage head 19 above the round can 15 2 , which is filled with annular superimposed deposited sliver 14 IV . With 15 1 an empty round can is called. The round cans 15 1 and 15 2 are each arranged on a rotatable can plate 27a and 27b. The can plates 27a, 27b are driven by a controllable drive motor 43 whose direction of rotation in the direction of the arrows L, N is reversible. With 44a, 44b are Designates pulleys which are connected via belts 45a and 45b to the shaft 43a of the drive motor 43.

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. Microcomputer, to which are connected: a control device 37 for the displacement device 38 (eg pneumatic cylinders 30a, 30b), a sensor 39 for filling a full can with sliver 14 IV , a motor control device 40 for the drive motor 41, z. B. electric motor, for the storage head 19 and a motor control device 42 for the drive motor 43 for the can plates 27a, 27b.
