Description

Die Erfindung betrifft eine Vorrichtung zum Überführen von stabförmigen Artikeln der tabakverarbeitenden Industrie, insbesondere Filterstäben, aus einem Vorrat in eine pneumatische Förderleitung, mit einer mit Aufnahmemulden versehenen drehbaren Fördertrommel, deren Aufnahmemulden trommelumfangsseitig in einer Beschickungszone queraxial mit einem Vorratsbehälter und trommelstirnseitig in einer Abgabezone längsaxial mit der stationären Förderleitung kommunizieren.The invention relates to a device for transferring rod-shaped articles of the tobacco processing industry, in particular Filter rods, from a supply to a pneumatic one Delivery line, with a rotatable with receiving troughs Conveyor drum, the receiving troughs on the drum circumference in a loading zone across the axis with a storage container and in a delivery zone at the end of the drum, longitudinally axially with the communicate stationary delivery line.

Eine Vorrichtung der eingangs bezeichneten Gattung ist beispielsweise in der US-PS 3 827 757 der Anmelderin dargestellt und beschrieben, wobei der Dichtklotz dazu beitragen soll, daß mit der Luftzuführung der Blasluft sowie mit der Luftführung im Bereich der Abgabezone eine sichere Überführung der Filterstäbe bei hoher Förderleistung gewährleistet ist und daß bei Störungen im Bereich der Abgabezone deren schnelle und einfache Zugänglichkeit möglich ist.A device of the type described at the outset is, for example in the applicant's U.S. Patent No. 3,827,757 and described, wherein the sealing block should help that with the air supply of the blown air and with the air duct in the Safe transfer of the filter rods in the area of the delivery zone is guaranteed at high capacity and that in the event of malfunctions in the area of the delivery zone, its quick and easy Accessibility is possible.

Der Erfindung liegt die Aufgabe zugrunde, derartige Vorrichtungen weiter zu verbessern.The invention has for its object such devices continue to improve.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Fördertrommel mit ihrer rotativ bewegten Trommelaußenfläche relativ zu den in der Abgabezone stationär angrenzenden Gegenflächen berührungsfrei angeordnet ist. Auf diese Weise ist eine praktisch verschleißfreie Betriebsstellung des Dichtklotzes im Bereich der die Abgabezone passierenden rotierenden Umfangsfläche der Fördertrommel gewahrleistet ohne nachteilige Auswirkungen auf die Schußfrequenz der pro Zeiteinheit überführten Filterstäbe. Überraschenderweise hat sich durch den durch die berührungs- und damit verschleißfreie stirnseitige Anstellung des Dichtklotzes gebildeten Entlüftungsspalt sogar eine beachtliche Leistungssteigerung für die pro Zeiteinheit geförderten Filterstäbe ergeben.
Eine berührungsfreie Umfangsanstellung des Dichtklotzes relativ zur Fördertrommel wird auf besonders einfache und funktionssichere Weise gemäß einer Weiterbildung dadurch erreicht, daß der Fördertrommel an ihren Stirnseiten von der spielfrei gelagerten Trommelachse durchdrungene, koaxiale, stationäre Stützbuchsen zugeordnet sind, deren dem Radius der Dichtfläche des Dichtklotzes angepaßte Umfangsfläche einen Durchmesser aufweist, der geringfügig größer ist als der Trommeldurchmesser der Fördertrommel. Durch die definierte doppelseitige Abstützung des Dichtklotzes wird außerdem eine sichere Dichtung zwischen den gegeneinander gepreßten Dichtflächen des Dichtklotzes und der Stützbuchsen erreicht, welche damit zugleich als Dichtbuchsen wirken, während die zwischen den Stützbuchsen angeordnete Fördertrommel relativ zu den angrenzenden Stützbuchsen sowie zum angrenzenden Flächenabschnitt des Dichtklotzes berührungsfrei rotiert.
Eine definierte und sichere Stütz- und Dichtwirkung zwischen dem Dichtklotz und den Stützbuchsen wird nach einem weiteren Vorschlag erreicht durch zwei radial und mittig zu den Stützbuchsen am Dichtklotz angreifenden Druckstempeln.
Um bei der erfindungsgemäßen Anstellung des Dichtklotzes eine üblicherweise durch diesen hindurchgeführte Blasluftversorgung der die Abgabezone durchlaufenden Trommelmulden zur Überführung der Filterstäbe in die Förderleitung mit hoher Betriebssicherheit und ohne Leckverluste zu gewährleisten, ist außerdem vorgesehen, daß die Druckstempel einen den Dichtklotz im Bereich der Druckluftversorgung unter Zwischenschaltung einer elastischen Dichtung aufnehmenden, als Versorgungsplatte ausgebildeten Tragkörper durchdringen und mit diesem in radialer Anstellrichtung des Dichtklotzes eine Schleppverbindung bilden, welche darüber hinaus zwischen den Druckstempeln und dem Tragkörper ein definiertes Spiel aufweist. Auf diese Weise wird einerseits eine sichere Abdichtung zwischen den Blasluftleitungsabschnitten im Dichtklotz und im Tragkörper erzielt, indem die elastische Dichtung vor der Abstützung des Dichtklotzes mit Vorspannung angelegt wird und andererseits eine quasi schwimmende Anlage des Dichtklotzes an den Stützbuchsen gewährleistet bleibt, indem sich der Dichtklotz optimal ausrichten und dichtend anlegen kann.
Eine der durch die Stempelpressung ausgeübten Stütz- und Dichtkraft widerstehende Gesamtverspannung des Systems wird nach einem weiteren Vorschlag dadurch erreicht, daß die Stützbuchsen über Zugtraversen mit einer ortsfesten Montageplatte starr verbunden sind, an welcher die als Druckluftzylinder ausgebildeten Antriebe der Druckstempel befestigt sind.
Die Funktionssicherheit bei der Anstellung des Dichtklotzes wird nach einer Weiterbildung noch dadurch erhöht, daß der Tragkörper Parallelführungen aufweist, die an der Montageplatte angeordnet sind, wobei darüber hinaus die Parallelführungen bzw. die Druckstempel vertikal ausgerichtet und betätigbar sind. Damit kann nach entsprechender automatischer Absenkung des Dichtklotzes leicht und schnell in die Abgabezone zur Beseitigung von Störungen eingegriffen werden.
Zusätzlich ist zwischen dem Dichtklotz und dem Tragkörper eine Zentrierstiftverbindung vorgesehen, welche vor der Anlage des Dichtklotzes für dessen Grobausrichtung sorgt.
Um an der an die Förderleitung angrenzenden Abschußseite des Dichtklotzes eine störungsfreie Führung der Filterstäbe über die durch die Dichtfläche der Stützbuchse gebildete Stufe bzw. Kante zu gewährleisten, ist gemäß einer vorteilhaften Ausgestaltung auf der an den im Bereich der Stützbuchse verlaufenden Förderleitungsabschnitt der pneumatischen Förderleitung angrenzenden Leitfläche des Dichtklotzes eine in Überführungsrichtung der Filterstäbe relativ zur Dichtfläche der Stützbuchse ansteigende Leitrampe vorgesehen. Diese Leitrampe wirkt quasi als Sprungschanze, um die Filterstäbe über die radial erhöhte Dichtfläche der Stützbuchse hinwegzuführen.
Insbesondere in Verbindung mit dem erfindungsgemäßen Umfangsspalt zwischen Dichtklotz und Fördertrommel wird durch eine zusätzlich vorgeschlagene Maßnahme eine deutliche Geräuschreduzierung der Vorrichtung erzielt. Diese konstruktive Weiterbildung besteht darin, daß an einem Ende an der, bezogen auf die Drehrichtung der Fördertrommel, auslaufseitigen Flanke des Dichtklotzes eine zur Stirnseite des Dichtklotzes hin abwärtsgeneigte Auslaufschräge vorgesehen ist. Auf diese Weise wird eine mit erheblichem Lärm verbundene schlagartige Entlüftung der von den Filterstäben befreiten und aus dem Umfangsbereich des Dichtklotzes auslaufenden Aufnahmemulden verhindert. Die Luft entweicht in zeitlich gestreckter Weise von einem Trommelende her über die ganze Muldenlänge aus der Aufnahmemulde in die Atmosphäre.This object is achieved in that the conveyor drum is arranged in a contactless manner with its rotating outer drum surface relative to the counter surfaces stationary adjacent in the delivery zone. In this way, a practically wear-free operating position of the sealing block in the area of the rotating peripheral surface of the conveyor drum passing through the delivery zone is ensured without adverse effects on the firing frequency of the filter rods transferred per unit of time. Surprisingly, the ventilation gap formed by the contact-free and therefore wear-free front-side adjustment of the sealing block has even resulted in a considerable increase in performance for the filter rods conveyed per unit of time.
A contact-free circumferential adjustment of the sealing block relative to the conveyor drum is achieved in a particularly simple and functionally reliable manner according to a further development in that the end face of the conveyor drum is assigned coaxial, stationary support bushings penetrated by the play-free drum axis, the circumferential surface of which is adapted to the radius of the sealing surface of the sealing block has a diameter that is slightly larger than the drum diameter of the conveyor drum. The defined double-sided support of the sealing block also ensures a secure seal between the sealing surfaces of the sealing block pressed against one another and the support bushes, which thus simultaneously act as sealing bushes, while the conveyor drum arranged between the support bushings is contact-free relative to the adjacent support bushings and to the adjacent surface section of the sealing block rotates.
A defined and secure support and sealing effect between the sealing block and the support bushings is achieved according to a further proposal by two pressure rams acting radially and centrally on the support bushings on the sealing block.
In order to ensure a blowing air supply, which is usually passed through this, of the drum troughs passing through the discharge zone for transferring the filter rods into the delivery line with high operational reliability and without leakage losses when the sealing block is set up according to the invention, it is also provided that the pressure stamps provide the sealing block in the area of the compressed air supply with interposition an elastic seal receiving, formed as a supply plate penetrate and form with this in the radial direction of the sealing block a towing connection, which also has a defined play between the pressure rams and the support body. In this way, a secure seal between the blow air line sections in the sealing block and in the supporting body is achieved by applying the elastic seal before the support of the sealing block with pretension and, on the other hand, a quasi-floating contact of the sealing block with the support bushing is ensured by the sealing block being optimal align and seal.
According to a further proposal, one of the total tensioning of the system which resists the support and sealing force exerted by the stamp pressure is achieved in that the support bushes are rigidly connected via traverse members to a stationary mounting plate, to which the drives of the pressure stamp designed as compressed air cylinders are fastened.
The functional reliability in the employment of the sealing block is further increased according to a further development in that the supporting body has parallel guides which are arranged on the mounting plate, the parallel guides and the pressure rams also being vertically aligned and operable. This means that after the sealing block has been lowered automatically, it is easy and quick to intervene in the dispensing zone to eliminate malfunctions.
In addition, a centering pin connection is provided between the sealing block and the supporting body, which ensures that the sealing block is roughly aligned before it is placed.
In order to ensure trouble-free guiding of the filter rods over the step or edge formed by the sealing surface of the support bush on the firing side of the sealing block adjacent to the delivery line, according to an advantageous embodiment, the guide surface of the pneumatic delivery line adjacent to the delivery line section running in the region of the support bushing of the sealing block is provided a guide ramp that rises in the direction of transfer of the filter rods relative to the sealing surface of the support bush. This guide ramp acts as a kind of ski jump to guide the filter rods over the radially raised sealing surface of the support bush.
In particular in connection with the circumferential gap between the sealing block and the conveyor drum according to the invention, a significantly reduced noise of the device is achieved by an additionally proposed measure. This constructional development consists in that at one end on the outlet-side flank of the sealing block, based on the direction of rotation of the conveying drum, there is provided an inclined downward slope toward the end face of the sealing block. In this way, an abrupt venting of the receiving troughs, which are freed of the filter rods and run out of the circumferential area of the sealing block, is associated with considerable noise. The air escapes from the end of the drum over the entire length of the bowl into the atmosphere in a time-stretched manner.

Der mit der Erfindung erzielte Vorteil besteht darin, daß eine praktisch verschleißfreie Betriebsweise der Überführungsvorrichtung mit dem zusätzlichen Effekt einer erheblichen Leistungssteigerung bei gleichzeitiger Geräuschminderung gewährleistet ist, wobei die Überführungsvorrichtung darüber hinaus bei Störungen nach automatisierter Öffnung gut zugänglich ist. The advantage achieved by the invention is that a practically wear-free operation of the transfer device with the added effect of a significant Performance increase with simultaneous noise reduction is guaranteed, the transfer device above well accessible in the event of faults after automated opening is.

Die in den Figuren 1 bis 7 dargestellte Überführungsvorrichtung weist eine Fördertrommel 1 auf, die mit Aufnahmemulden 2 für Filterstäbe 3 versehen ist. Die mit Saugbohrungen 4 versehenen sowie von Stegen 6 begrenzten Aufnahmemulden 2 verlaufen parallel zur Drehachse 7 der Fördertrommel 1 und sind nach außen, daß heißt auf der der Drehachse 6 abgewandten Seite, offen. Die Fördertrommel 1 ist durch einen als Moduleinzelantrieb gestalteten Motor 8 über Zahnräder 9, 11 mittels einer Welle 12 in Richtung des Pfeils 13 kontinuierlich antreibbar und wirkt mit ihren Aufnahmemulden 2 trommelumfangsseitig in einer oberen Beschickungszone B queraxial mit einem Vorratsbehälter 14 zur Entnahme der Filterstäbe 3 und trommelstirnseitig in einer unteren Abgabezone C längsaxial mit einer stationären pneumatischen Förderleitung 16 zusammen, in welche die Filterstäbe 3 zur Weiterleitung an Verarbeitungseinrichtungen mittels Druckluft überführt werden. Zu diesem Zweck ist der Fördertrommel 1 ein im Bereich der Abgabezone C anstellbarer bzw. absenkbarer Dichtklotz 17 zugeordnet, welcher eine der kreisbogenförmigen Bahn der Fördertrommel 1 angepaßte Gegenfläche 18 aufweist. Im angestellten Zustand stützt sich der Dichtklotz 17 ausschließlich an seinen beiden Enden mit seiner Gegenfläche 18 dichtend an zwei konzentrisch zur Fördertrommel 1 angeordneten, ortsfesten Stützbuchsen 19 und 21 ab, deren Außenradius dem Radius der Gegenfläche 18 entspricht, jedoch geringfügig größer ist als der Außenradius der Fördertrommel 1. Auf diese Weise ergibt sich ein Spiel 25 und damit eine berührungsfreie Anstellung zwischen der durch die Stege 6 gebildeten Trommelumfangsfläche und der Gegenfläche 18 des Dichtklotzes 17.
Die Welle 12 der Fördertrommel 1 ist durch die Stützbuchsen 19, 21 hindurchgeführt und außerhalb der Stützbuchsen in ortsfesten Gehäusewänden 22, 23 radial spielfrei gelagert. Die Stützbuchsen 19, 21 selbst sind über Zugtraversen 24 fest mit einer stationären Montageplatte 26 verbunden, welche außerdem zwei vertikal angeordnete Parallelführungen 27 für den Dichtklotz 17 bzw. für einen den Dichtklotz 17 stützenden Tragkörper 28 sowie zwei Druckluftzylinder 29 für zwei Druckluftkolben 30 zur vertikalen Auf- und Abbewegung des Dichtklotzes 17 bzw. des Tragkörpers 28 aufnimmt. Durch die in vertikaler Richtung erfolgende und geführte Anstellung des Dichtklotzes 17 wird die exakte Einhaltung eines stirnseitigen Entlüftungsspaltes 31 im Bereich der Abgabezone C zwischen der Fördertrommel 1 und der angrenzenden Gegenfläche der Stützbuchse 19 erzielt.
Der den Dichtklotz 17 aufnehmende Tragkörper 28 ist zugleich als Versorgungsplatte ausgebildet zur Zuführung von Druckluft bzw. Schußluft in die Aufnahmemulden 2 zum längsaxialen Überführen der Filterstäbe 3 in die Förderleitung 16, wozu die Fördertrommel 1 einen Steuerflansch 32 mit einer jeden Aufnahmemulde 2 zugeordneten Steuerschlitzen 33 aufweist. Der Tragkörper 28 ist zu diesem Zweck an eine schwenkbare Schußluftzuführung 34 angeschlossen und von einer Schußluftbohrung 36 durchsetzt, die in Querrichtung innerhalb eines Dichtringes 37 zwischen Tragkörper 28 und Dichtklotz 17 mit einer mit den Steuerschlitzen 33 der Fördertrommel 1 verbindbaren Querbohrung 38 kommuniziert.
Die beiden Druckluftkolben 30 sind am Ende mit einem den Tragkörper 28 durchdringenden Druckstempel 39 versehen, der mit seiner Stirnseite mittig am Dichtklotz 17 angreift und innerhalb des Tragkörpers 28 mit diesem mittels einer Ringnut 41 eine Schleppverbindung 42 bildet, die ein definiertes Radialspiel aufweist.
Zwischen dem Tragkörper 28 und dem Dichtklotz 17 besteht darüber hinaus eine Zentrierstiftverbindung 43, die bei einer Grobausrichtung ein schwimmendes Anlegen des Dichtklotzes 17 und damit eine Selbstzentrierung des Dichtklotzes 17 an den Stützbuchsen 19, 21 gewährleistet.
Die der Abgabezone C benachbarte Stützbuchse 19 ist oberhalb ihrer den Dichtklotz 17 kontaktierenden Dichtfläche 44 von einer achsparallelen, mit der Förderleitung 16 fluchtenden Überführungsbohrung 46 durchsetzt. Um die Filterstäbe 3 störungsfrei über die stirnseitig an der Stütz- und Dichtfläche 44 gebildete Kante zu führen, ist vor der Kante eine in Schußrichtung (Pfeil 47) relativ zur Dichtfläche 44 ansteigende Leitrampe 48 für die Filterstäbe 3 in die angrenzende Stütz- und Dichtfläche des Dichtklotzes eingelassen.
Der Dichtklotz 17 ist darüber hinaus an seiner, bezogen auf die Drehrichtung (Pfeil 13) der Fördertrommel 1, auslaufseitigen Flanke 49 mit einer zur Stirnseite bzw. zur Stützbuchse 19 in der Abgabezone C hin abwärtsgeneigten Auslaufschräge 50 versehen.The transfer device shown in Figures 1 to 7 has a conveyor drum 1, which is provided with receiving troughs 2 for filter rods 3. The receiving troughs 4 provided with suction bores 4 and delimited by webs 6 run parallel to the axis of rotation 7 of the conveyor drum 1 and are open to the outside, that is to say on the side facing away from the axis of rotation 6. The conveyor drum 1 can be continuously driven by a motor 8 designed as a module single drive via gears 9, 11 by means of a shaft 12 in the direction of arrow 13 and acts with its receiving troughs 2 on the drum circumference in an upper loading zone B transversely axially with a storage container 14 for removing the filter rods 3 and the end of the drum in a lower discharge zone C along a longitudinal axis with a stationary pneumatic conveying line 16, into which the filter rods 3 are transferred by compressed air for forwarding to processing devices. For this purpose, the conveyor drum 1 is assigned a sealing block 17 which can be adjusted or lowered in the region of the delivery zone C and which has a counter surface 18 which is adapted to the arcuate path of the conveyor drum 1. In the employed state, the sealing block 17 is supported exclusively at its two ends with its counter surface 18 sealingly on two stationary support bushes 19 and 21 arranged concentrically to the conveying drum 1, the outer radius of which corresponds to the radius of the counter surface 18, but is slightly larger than the outer radius of the Conveyor drum 1. This results in a play 25 and thus a contact-free employment between the peripheral drum surface formed by the webs 6 and the counter surface 18 of the sealing block 17th
The shaft 12 of the conveyor drum 1 is guided through the support bushings 19, 21 and is mounted radially free of play outside of the support bushings in stationary housing walls 22, 23. The support bushings 19, 21 themselves are firmly connected to a stationary mounting plate 26 via traverse members 24, which also has two vertically arranged parallel guides 27 for the sealing block 17 or for a supporting body 28 supporting the sealing block 17, and two compressed air cylinders 29 for two compressed air pistons 30 for vertical opening - And movement of the sealing block 17 and the support body 28 takes up. Through the vertical and guided adjustment of the sealing block 17, the exact adherence to an end ventilation gap 31 is achieved in the area of the discharge zone C between the conveyor drum 1 and the adjacent counter surface of the support bushing 19.
The support body 28 receiving the sealing block 17 is at the same time designed as a supply plate for supplying compressed air or shot air into the receiving troughs 2 for longitudinally transferring the filter rods 3 into the delivery line 16, for which purpose the delivery drum 1 has a control flange 32 with a control slot 33 assigned to each receiving trough 2 . For this purpose, the support body 28 is connected to a pivotable weft air supply 34 and penetrated by a weft air bore 36 which communicates in the transverse direction within a sealing ring 37 between the support body 28 and sealing block 17 with a cross bore 38 which can be connected to the control slots 33 of the conveyor drum 1.
The two compressed air pistons 30 are provided at the end with a pressure ram 39 which penetrates the support body 28 and which engages with its end face in the center of the sealing block 17 and forms a drag connection 42 within the support body 28 by means of an annular groove 41 which has a defined radial play.
Between the support body 28 and the sealing block 17 there is also a centering pin connection 43 which, in the case of a rough alignment, ensures a floating contact of the sealing block 17 and thus self-centering of the sealing block 17 on the support bushings 19, 21.
The support bushing 19 adjacent to the delivery zone C is penetrated by an axially parallel transfer bore 46 aligned with the delivery line 16 above its sealing surface 44 contacting the sealing block 17. In order to guide the filter rods 3 without interference over the edge formed on the end face on the support and sealing surface 44, a guide ramp 48 for the filter rods 3 rising in the weft direction (arrow 47) relative to the sealing surface 44 is in the adjacent support and sealing surface of the Sealing block embedded.
The sealing block 17 is also provided on its outlet side flank 49 with respect to the direction of rotation (arrow 13) of the conveying drum 1 with an outlet slope 50 which is inclined downwards towards the end face or to the support bushing 19 in the delivery zone C.

Die Wirkungsweise der Überführungvorrichtung ist wie folgt:
Zur Inbetriebnahme wird der Dichtklotz 17 aus seiner beispielsweise aus Reinigungsgründen abgesenkten Position gemäß den Figuren 3, 4 in die in den Figuren 1, 2, 5, 6, 7 dargestellte Betriebsposition bewegt. Hierzu werden die Druckluftzylinder 29 beaufschlagt, so daß die Druckstempel 39 den Dichtklotz 17 sowie über die Schleppverbindung 42 den Tragkörper 28 entlang der Parallelführungen 27 aufwärtsbewegen. Die Bewegungsfreiheit des Druckstempels 39 relativ zum Tragkörper 28 bzw. das Spiel in der Schleppverbindung 42 in Anstellrichtung ist so bemessen, daß unter praktisch schwimmender und dichtender Anlage des Dichtklotzes 17 an den Stützbuchsen 19, 21 der Dichtring 37 zwischen dem Tragkörper 28 und dem Dichtklotz 17 unter Vorspannung anliegt, wobei die Zugtraversen 24 die auf die Stützbuchsen 19, 21 ausgeübten Druck- und Biegekräfte auffangen und das System in sich verspannen. Hingegen verbleibt wegen des geringeren Trommeldurchmessers der Fördertrommel 1 ein definierter Freiraum 25 zwischen der Umfangsfläche der Fördertrommel 1 und dem Dichtklotz 17, so daß ein reibungs- und damit verschleißfreier Betrieb möglich ist.
Während des Betriebes übernimmt die über die Welle 12 mit konstanter Drehzahl angetriebene Fördertrommel 1 in der Beschickungszone B in ihre Aufnahmemulden 2 Filterstäbe 3 aus dem im Vorratsbehälter 14 über der Fördertrommel 1 befindlichen Vorrat von Filterstäben. Die Filterstäbe 3 werden in den Aufnahmemulden 2 von der Fördertrommel 1 aus der Beschickungszone B in die Abgabezone C überführt, in der die Filterstäbe 3 axial direkt aus den Aufnahmemulden 2 in die pneumatische Förderleitung 16 während der Drehung der Fördertrommel 1 bewegt werden sollen. Fluchtet eine Aufnahmemulde 2 mit der pneumatischen Förderleitung 16 bzw. mit der Überführungsbohrung 46 in der Stützbuchse 19, dann kann Druckluft aus der Schußluftzuführung 34 über die Bohrung 36 im Tragkörper 28, die Querbohrung 38 im Dichtklotz 17 sowie über einen zugeordneten Steuerschlitz 33 in die Aufnahmemulde 2 strömen, den darin befindlichen Filterstab 3 in Richtung des Pfeils 47 axial bewegen und ihn über die als Sprungschanze wirkende Leitrampe 48 in die Förderleitung 16 überführen.
Hierbei hat sich überraschenderweise gezeigt, daß die permanente Entlüftung über den Entlüftungsspalt 31 eine den Staudruck reduzierende und die Leistung steigernde Wirkung hat, indem eine erheblich höhere Überführungsrate der Filterstäbe pro Zeiteinheit erzielt wird.
Beim Austreten der vom Filterstab 3 befreiten, noch unter Überdruck stehenden Aufnahmemulde 2 in Drehrichtung 13 an der Flanke 49 des Dichtklotzes 17 verhindert die Auslaufschräge 50 eine schlagartige Entlüftung der Aufnahmemulde 2 in die Atmosphäre, was zu einer wesentlichen Reduzierung der Betriebsgeräusche führt.The transfer device works as follows:
For commissioning, the sealing block 17 is moved from its position, for example, as shown in FIGS. 3, 4, into the operating position shown in FIGS. 1, 2, 5, 6, 7. For this purpose, the compressed air cylinders 29 are acted on, so that the pressure rams 39 move the sealing block 17 and, via the drag connection 42, the support body 28 upwards along the parallel guides 27. The freedom of movement of the plunger 39 relative to the support body 28 or the play in the towing connection 42 in the direction of adjustment is such that, with the sealing block 17 practically floating and sealingly against the support bushings 19, 21, the sealing ring 37 between the support body 28 and the sealing block 17 is present under pretension, the traverse members 24 absorbing the pressure and bending forces exerted on the support bushings 19, 21 and bracing the system. On the other hand, because of the smaller drum diameter of the conveyor drum 1, a defined free space 25 remains between the peripheral surface of the conveyor drum 1 and the sealing block 17, so that friction-free and therefore wear-free operation is possible.
During operation, the conveyor drum 1, which is driven by the shaft 12 at a constant speed, takes over 2 filter rods 3 in the loading trough B into its receiving troughs from the supply of filter rods located in the storage container 14 above the conveyor drum 1. The filter rods 3 are transferred in the receiving troughs 2 from the conveyor drum 1 from the loading zone B into the delivery zone C, in which the filter rods 3 are to be moved axially directly from the receiving troughs 2 into the pneumatic conveying line 16 during the rotation of the conveyor drum 1. If a receiving trough 2 is aligned with the pneumatic delivery line 16 or with the transfer bore 46 in the support bush 19, then compressed air from the shot air supply 34 can pass through the bore 36 in the support body 28, the transverse bore 38 in the sealing block 17 and via an associated control slot 33 into the receiving trough 2 flow, move the filter rod 3 located therein axially in the direction of arrow 47 and transfer it via the guide ramp 48 acting as a ski jump into the delivery line 16.
It has surprisingly been found here that the permanent ventilation via the ventilation gap 31 has an effect which reduces the dynamic pressure and increases the performance by achieving a considerably higher transfer rate of the filter rods per unit of time.
When the receiving trough 2, which has been freed from the filter rod 3 and is still under pressure, in the direction of rotation 13 on the flank 49 of the sealing block 17, the outlet slope 50 prevents a sudden venting of the receiving trough 2 into the atmosphere, which leads to a substantial reduction in operating noise.
