Description

Die Erfindung betrifft einen rotativen Behälterträger für eine Behälterbehandlungsmaschine, mit mehreren, Behälter unterschiedlicher Querschnitte handhabenden Behälteraufnehmern, die bei rotierendem Behälterträger beim Passieren von wenigstens zwei entlang der Umlaufbahn des Behälterträgers angeordneten Arbeitsstationen durch zwei ortsfeste, in Umfangsrichtung gegeneinander versetzte Zahnkurven sowie durch mit den Behälteraufnehmern gekoppelten und mit den Zahnkurven kämmenden Rollensternen entgegen der Drehrichtung des Behälterträgers in Eigendrehung versetzt werden.The invention relates to a rotary container carrier for a container treatment machine, with a plurality of container receptacles which handle containers of different cross-sections and, with the toothed wheels meshing with toothed curves, are set to rotate in the opposite direction to the direction of rotation of the container carrier.

Ein Behälterträger der eingangs bezeichneten Art kommt bei Maschinen (siehe z.B. DE-A-3 307 662) zum Einsatz, auf denen vielfältige Bearbeitungsvorgänge mit den unterschiedlichsten Bewegungsabläufen vorgenommen werden, angefangen vom relativen Stillstand über kurze oszillierende Schwenkungen bis hin zur mehrmaligen kontinuierlichen Drehung der Behälteraufnehmer, die insbesondere bei der Hochleistungs-Rundumetikettierung von Gefäßen, zum Beispiel Dosen oder wiederverwendbaren PET-Flaschen der Getränkeindustrie, erforderlich ist.A container carrier of the type described at the outset is used in machines (see, for example, DE-A-3 307 662), on which a variety of machining processes with the most varied of movement sequences are carried out, starting from the relative standstill via short oscillating swings up to repeated continuous rotation of the container receptacles , which is particularly necessary for high-performance all-round labeling of containers, for example cans or reusable PET bottles from the beverage industry.

Der Erfindung liegt die Aufgabe zugrunde, die Flexibilität bzw. die Anpassung einer derartigen Vorrichtung hinsichtlich der in unterschiedlichen Größen zu handhabenden Behälter weiter zu verbessern.The invention has for its object to further improve the flexibility or the adaptation of such a device with regard to the containers to be handled in different sizes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zahnkurven einen Kurvenverlauf aufweisen, der ein einziges Drehprogramm umfaßt, welches für einen durch Endpunkte bestimmter Kurvenabschnitte markierten minimalen und maximalen Behälterquerschnitt ausgelegt ist, wobei die Zahnkurven in Umfangsrichtung (Winkel β) derart stufenlos einstellbar sind, daß jeweils gleiche Punkte einander entsprechender Kurvenabschnitte bestimmten Positionen an den in definiertem Winkelabstand zueinander angeordneten Arbeitsstationen zugeordnet sind.
Bei einer Ausgestaltung, gemäß der die erste Arbeitsstation durch eine Beleimungsvorrichtung und die zweite Arbeitsstation durch eine Etikettierstation gebildet wird, wobei nach einer zusätzlichen Weiterbildung die Zahnkurven oberseitig sowie konzentrisch zu einem die Behälter freihängend aufnehmenden Behälterträger angeordnet sind, ist es erforderlich, die Stelle der zwecks Rundumetikettierung durch die Beleimungsvorrichtung an den Behälter angebrachten Anfangsbeleimung exakt in einer Entnahmeposition an der Etikettierstation mit dem jeweils zu entnehmenden Rundumetikett tangieren zu lassen. Dies wird nach einer besonders vorteilhaften Ausgestaltung dadurch erreicht, daß in Abstimmung auf den jeweiligen Behälterquerschnitt die Punkte auf den Kurvenabschnitten immer bestimmten Winkelpositionen der Rollensterne relativ zu den Arbeitsstationen entsprechen.
Um sicherzustellen, daß Behälter eines bestimmten Querschnittes sich mit einer beleimten Umfangszone exakt auf dem Anfangsbereich des ortsfesten Etikettenstapels bzw. dem vorderen Randbereich der Rundumetiketten abwälzen können, d. h. ihre Absolutgeschwindigkeit im außenliegenden Bereich ihrer Umfangsbahn gleich Null ist, wird weiterhin vorgeschlagen, daß in Abstimmung auf den jeweiligen Behälterquerschnitt die Punkte auf den Kurvenabschnitten immer bestimmten Umfangsgeschwindigkeiten der mit den Behälteraufnehmern entgegengesetzt zum Behälterträger rotierenden Behälter entsprechen, derart, daß jeweils ein in bestimmter Winkelposition der Rollensterne die Arbeitsstationen passierender äußerster Behälterumfangsabschnitt stillsteht.
This object is achieved in that the toothed curves have a curve which comprises a single turning program which is designed for a minimum and maximum container cross-section marked by end points of certain curve sections, the toothed curves in The circumferential direction (angle β) can be infinitely adjusted such that the same points of corresponding curve sections are assigned to specific positions at the work stations arranged at a defined angular distance from one another.
In one embodiment, according to which the first work station is formed by a gluing device and the second work station is formed by a labeling station, and according to an additional development, the tooth curves are arranged on the top side and concentrically to a container carrier that holds the containers freely suspended, it is necessary to replace the container Allow all-round labeling to be affected by the initial gluing applied to the container exactly in a removal position at the labeling station with the all-round label to be removed. According to a particularly advantageous embodiment, this is achieved in that the points on the curve sections always correspond to certain angular positions of the roller stars relative to the work stations, in coordination with the respective container cross section.
In order to ensure that containers of a certain cross-section with a glued peripheral zone can roll exactly on the starting area of the stationary label stack or the front edge area of the all-round labels, i.e. their absolute speed in the outer area of their peripheral path is zero, it is further proposed that in coordination the respective cross-section of the container, the points on the curve sections always correspond to certain peripheral speeds of the containers rotating with the container receptacles opposite to the container carrier, in such a way that in each case an outermost container circumferential section passing through the workstations in a certain angular position of the roller stations stands still.

Die Anordnung ist gemäß einer Weiterbildung dabei so getroffen, daß in jeder Einstellposition (Winkel β) der Zahnkurven die Rollensterne zwischen zwei Arbeitsstationen wenigstens einen Kurvenabschnitt für das gesamte zwischen dem minimalen und maximalen Behälterquerschnitt liegende Geschwindigkeitsspektrum durchlaufen.
Die erste Arbeitsstation und die zweite Arbeitsstation sind darüber hinaus in einem derartigen Winkelabstand (Winkel α) zueinander angeordnet, daß die Rollensterne mit einem Behälter beliebigen Querschnitts in einem diesem Winkelabstand entsprechenden Drehwinkelbereich (Drehwinkel φ) des Behälterträgers eine Eigendrehung um 360° ausführen.
Um mit Hilfe der erfindungsgemäßen Anordnung höhere Eigenrotationsgeschwindigkeiten der Behälteraufnehmer bei der Hochleistumgs-Rundumetikettierung zu erzielen, ist es ohne weiteres denkbar, zwischen den Rollensternen und den Behälteraufnehmern ein Übersetzungsgetriebe vorzusehen.
According to a further development, the arrangement is such that in each setting position (angle β) of the tooth curves Roll stars between two workstations pass through at least one curve section for the entire speed spectrum lying between the minimum and maximum container cross section.
The first work station and the second work station are also arranged at such an angular distance (angle α) from one another that the roller stars with a container of any cross section within a rotation angle range (angle of rotation φ) of the container carrier corresponding to this angular distance execute a self-rotation by 360 °.
In order to achieve higher self-rotation speeds of the container receptacles with the high-performance all-round labeling with the aid of the arrangement according to the invention, it is readily conceivable to provide a transmission gear between the roller stars and the container receptacles.

Der mit der Erfindung erzielte Vorteil besteht darin, daß bei allen denkbaren Behältergrößen innerhalb eines definierten Querschnittsbereichs exakt jeder Drehwinkelstellung des die Behälter transportierendem Behälterträgers eine definierte Ausrichtung bzw. Drehwinkelstellung der die Behälter tragenden Behälteraufnehmer bzw. der diese führenden Rollensterne bezüglich eines an der jeweiligen Position vorzusehenden Aggregates oder vorzunehmenden Bearbeitungsvorganges zugeordnet werden kann. Auf diese Weise ist es insbesondere möglich, bei der Rundumetikettierung eines Gefäßes eine zuvor auf das Gefäß aufgebrachte Leimstelle exakt in eine Kontaktposition mit einer Etiketten-Entnahmestelle zu bringen.The advantage achieved by the invention is that, for all conceivable container sizes within a defined cross-sectional area, exactly each rotational angle position of the container carrier transporting the containers has a defined orientation or rotational angle position of the container receptacles carrying the containers or the roller stars guiding them with respect to one at the respective position Aggregates or processing operations can be assigned. In this way it is in particular possible, when labeling a container all around, to bring a glue point previously applied to the container exactly into a contact position with a label removal point.

Die Erfindung wird nachstehend anhand des im dem beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to the embodiment shown in the accompanying figures.

Die mit dem erfindungsgemäßen Behälterträger 1 ausgestattete Etikettiermaschine dient zum Etikettieren vom PET-Flaschen 2 mit sogenannten Rundumetiketten 3. Dem Behälterträger 1 ist zu diesem Zweck bezogen auf seine Förderrichtung (Pfeil 4) aufeinanderfolgend am der Peripherie ein in Pfeilrichtung 6 synchron zum Behälterträger 1 umlaufender Einlaufstern 7 zum Zuführen der Flaschen 2, eine erste Arbeitsstation in Form einer als Leimdüse ausgebildeten Beleimungsvorrichtung 8 zum Aufbringen einer Anfgangsbeleimung auf die Flaschen 2 sowie eine zweite Arbeitsstation im Form einer Etikettierstation 9 zugeordnet, an der die Etiketten 3 direkt vom den Flaschen 2 entnommen und dabei um diese mit Unterstützung durch eine Anbürstvorrichtung 11 herumgewickelt werden. Die einem Etikettenstapel 12 tragende Etikettierstation 9 und die Beleimungsvorrichtung 8 sind in einem bestimmtem Winkelabstand (Winkel α) zueinander ortsfest angeordnet und lediglich radial im Anpassung an unterschiedliche Flaschemdurchmesser anstellbar bzw. die Etikettierstation 9 zwecks Etikettierung größerer Flaschen zur Aufnahme gestrichelt angedeuteter größerer Etiketten 3 einrichtbar.
Der Winkelabstand (Winkel α) bezeichnet zugleich den Winkel für eine volle Flaschendrehung um 360° in Richtung des Pfeils 13, d. h. entgegen der Drehrichtung (Pfeil 4) des Behälterträgers 1 unabhängig vom jeweiligen Flaschendurchmesser.
In dem Figuren 2 und 3 sind abwechselnd Flaschen 2 mit kleinem und großem Querschnitt auf einem Umfangsabschnitt des Behälterträgers 1 angedeutet, wobei mit dem Flaschenquerschnitt der Umfangsbereich gemeint ist, um den das Rundumetikatt 3 gewickelt wird. Der Behälterträger 1 ist zu diesem Zweck mit die Flaschen 2 freihängend von oben erfassenden Behälteraufnehmern 14 versehen, welche in regelmäßigen Abständen entgegengesetzt drehbar (Pfeil 13) in dem um eine zentrale Achse 16 mit verschiedenem Drehzahlen antreibbaren Behälterträger 1 gelagert sind.
Die während der Behälterdrehung erzeugte entgegengerichtete Eigendrehung der Behälteraufnehmer 14 wird durch zwei in Umfangsrichtung um 180° gegeneinander versetzte, ortsfeste Zahnkurven 17 und 18 einer doppelstöckigen Steuerkurve 19 in Zusammenwirkung mit Rollensternen 21 eingeleitet. Die Rollensterne 21 werden gebildet durch eine am oberen Ende der Behälteraufnehmer 14 angeordnete Scheibe 22 mit jeweils vier Kurvenrollen 23, die gegeneinander um 90° versetzt sind und auf dem gleichen Teilkreis liegen. Die Kurvenrollen 23 sind abwechselnd an der Oberseite und an der Unterseite der Scheibe 22 angeordnet und arbeiten mit der oberen bzw. unteren Zahnkurve 17 bzw. 18 zusammen.
Die konzentrisch zur Drehachse 16 des Behälterträgers 1 verlaufenden Zahnkurven 17 und 18 umfassen von einem minimalen Flaschenquerschnitt bis zu einem maximalen Flaschenquerschnitt der Flaschen 2 bzw. für alle dazwischenliegenden Flaschenquerschnitte ein einziges Drehprogramm und sind zu diesem Zweck stufenlos bzw. maximal um den Winkel β um die Achse 16 in Umfangsrichtung einstellbar, so daß für jeden denkbaren Flaschenquerschnitt jeweils gleiche Punkte B und B₁ bzw. A und A₁ einander entsprechender, in Figur 4 schraffiert unterlegter Kurvenabschnitte für die Winkelgeschwindigkeit ω an der Beleimungsvorrichtung 8 und an einer Anfangs-Entnahmestelle 24 der Etikettierstation 9 wirksam sind.
In Figur 4 ist mit φ der Drehwinkel des Behälterträgers 1, und mit ω die durch den Kurvenabschnitt 26 für die Rastphase, durch die schraffiert unterlegten Kurvenabschnitte AB und A₁B₁ für die Beleimung bzw. die Etikettierung und den Kurvenabschnitt 27 für eine gleichförmige Drehung entlang der Anbürstvorrichtung 11 kenntlich gemachte Winkelgeschwindigkeit der drehenden Flaschen wiedergegeben. Die Bezeichnung β entspricht dem in den Figuren 2 und 3 angegebenen maximalen Einstellwinkel der Zahnkurven 17, 18 zwischen dem durch die Punkte B, B₁ markierten größten Flaschendurchmesser und durch die Punkte A, A₁ markierten kleinsten Flaschendurchmesser im Beleimungs- bzw. Etikettierbereich. Die Bezeichnung α entspricht dem in den Figuren 2 und 3 angegebenen Winkelabstand zwischen den Arbeitsstationen 8 und 9.
Alle denkbaren, im Beleimungsbereich bzw. im Etikettierbereich zwischen den Endpunkten A und B bzw. A₁ und B₁ liegenden Punkte entsprechen zwischen dem minimalen und maximalen Flaschenquerschnitt liegenden Flaschenquerschnitten, und die jeweilige Steigung in den korrespondierenden Punkten der Kurvenabschnitte AB, A₁, B₁ damit bestimmten Winkelgeschwindigkeiten .
In Figur 3 sind für abwechselnd eingezeichnete, mit 2A und 2B bezeichnete kleine und große Flaschen entsprechende Drehstellungen der Rollensterne 21 dargestellt, wobei die mit der unteren Zahnkurve 18 kämmenden Kurvenrollen mit 23U1 und 23U2 sowie die mit der oberen Zahnkurve 17 kämmenden Kurvenrollen mit 23O bezeichnet sind.
Aus Figur 3 ist ersichtlich, daß beispielsweise bei den dort auf den kleinsten Flaschenquerschnitt eingestellten Zahnkurven 17, 18 die Stellung des Rollensterns 21 an der Beleimungsvorrichtung 8 und der Etikettierstation 9 gleich sind, so daß aufgrund der vollen Drehung des Behälters 2A um 360° die Leimstelle des Behälters exakt die Entnahmestelle 24 an der Etikettierstation 9 tangiert und ein Etikett durch eine Abwälzbewegung entnimmt.
Die für den kleinen Flaschenquerschnitt exakt an der Beleimungsstelle 8 und der Entnahmestelle 24 wirksam werdenden Steigungspunkte der entsprechenden Kurvenabschnitte der Zahnkurven 17, 18 bewirken eine derartige Winkelgeschwindigkeit der Flasche 2A, daß ihre Umfangsgeschwindigkeit genau an den genannten Stellen 8 und 24 relativ zu den ortsfesten Stationen 8 bzw. 9 zu Null wird. Entsprechendes gilt für alle in Stellbereich den Winkels β liegenden Flaschenquerschnitte des durch den minimalen und maximalen Flaschenquerschnitt der Flasche 2A und 2B begrenzten einzigen Drehprogramms.
Dieses einzige Drehprogramm wird bei jeder Winkelstellung der Zahnkurven 17, 18 von den Rollensternen 21 zwischen den Stationen 8 und 9 immer komplett, d. h. in allen Geschwindigkeitsbereichen durchlaufen, wobei die dem jeweiligen Flaschendurchmesser entsprechenden, entscheidenden Kurvenpunkte immer an den genannten Stellen 8 bzw. 24 wirksam sind.
Die gemeinsame Verstellung der Zahnkurven 17, 18 erfolgt gemäß Figur 1 nach Lösen einer Klemmschraube 28 anhand einer Einstellmarkierung 29 für den auf den Flaschendurchmesser bezogenen Winkel β durch Drehen eines Kurventrägers 31 mittels eines Drehmomentsstützrahmens 32. Die Beleimungsvorrichtung 8 und die Etikettierstation 9 verbleiben in jedem Fall an ihrer vorgesehenen ortsfesten Winkelposition bezüglich der Umlaufbahn des Behälterträgers 1 und werden nur in ihrer radialen Anstellung an den jeweiligen Flaschendurchmesser angepaßt.
The labeling machine equipped with the container carrier 1 according to the invention serves for labeling PET bottles 2 with so-called all-round labels 3. For this purpose, the container carrier 1 is successively on the periphery in relation to its conveying direction (arrow 4) on the periphery in the direction of the arrow 6 in synchronism with the container carrier 1 7 for feeding the bottles 2, a first work station in the form of a gluing device designed as a glue nozzle for applying an initial gluing to the bottles 2 and a second work station in the form of a labeling station 9, at which the labels 3 are removed directly from the bottles 2 and thereby around them with the support of a brushing device 11. The labeling station 9 carrying a label stack 12 and the gluing device 8 are arranged in a fixed angular distance (angle α) from one another and can only be adjusted radially to adapt to different bottle diameters, or the labeling station 9 can be set up for labeling larger bottles to accommodate larger labels 3 indicated by dashed lines.
The angular distance (angle α) also designates the angle for a full bottle rotation through 360 ° in the direction of arrow 13, ie counter to the direction of rotation (arrow 4) of the container carrier 1, regardless of the respective bottle diameter.
In FIGS. 2 and 3, bottles 2 with a small and large cross-section are alternately indicated on a peripheral section of the container carrier 1, the bottle cross-section being the peripheral region around which the all-round label 3 is wound. For this purpose, the container carrier 1 is provided with the bottles 2 hanging freely from the top of the container receptacles 14, which are rotated in opposite directions at regular intervals (arrow 13) in the container carrier 1, which can be driven around a central axis 16 at different speeds.
The opposite direction generated during the container rotation Internal rotation of the container receptacles 14 is initiated by two fixed toothed curves 17 and 18, offset in the circumferential direction from one another in the circumferential direction, of a two-story control curve 19 in cooperation with roller stars 21. The roller stars 21 are formed by a disc 22 arranged at the upper end of the container receptacles 14, each with four cam rollers 23, which are offset from one another by 90 ° and lie on the same pitch circle. The cam rollers 23 are arranged alternately on the upper side and on the lower side of the disk 22 and work together with the upper and lower toothed curves 17 and 18, respectively.
The tooth curves 17 and 18, which run concentrically to the axis of rotation 16 of the container carrier 1, comprise a single turning program from a minimum bottle cross-section to a maximum bottle cross-section of the bottles 2 or for all bottle cross-sections in between and are stepless for this purpose or at most by the angle β by Axis 16 adjustable in the circumferential direction, so that for each conceivable bottle cross-section the same points B and B₁ or A and A₁ of corresponding curve sections shaded in FIG. 4 for the angular velocity ω at the gluing device 8 and at an initial removal point 24 of the labeling station 9 are effective.
In Figure 4 with φ the angle of rotation of the container carrier 1, and with ω by the curve section 26 for the rest phase, by the hatched curve sections AB and A₁B₁ for gluing or labeling and the curve section 27 for a uniform rotation along the brushing device 11 indicated indicated angular velocity of the rotating bottles. The designation β corresponds to the maximum setting angle of the tooth curves 17, 18 indicated in FIGS. 2 and 3 between the largest bottle diameter marked by points B, B₁ and the smallest bottle diameter marked by points A, A₁ in the gluing or Labeling area. The designation α corresponds to the angular distance between the work stations 8 and 9 indicated in FIGS. 2 and 3.
All conceivable, in the gluing area or in the labeling area between the end points A and B or A₁ and B₁ lying points correspond between the minimum and maximum bottle cross-sections lying bottle cross-sections, and the respective slope in the corresponding points of the curve sections AB, A₁, B₁ thus certain angular velocities .
In FIG. 3, corresponding rotating positions of the roller stars 21 are shown for small and large bottles alternately shown with 2A and 2B, the cam rollers meshing with the lower tooth curve 18 with 23 U1 and 23 U2 and the cam rollers meshing with the upper tooth curve 17 with 23 O are designated.
From Figure 3 it can be seen that, for example, with the tooth curves 17, 18 set there to the smallest bottle cross-section, the position of the roller star 21 on the gluing device 8 and the labeling station 9 are the same, so that the glue point is 360 ° due to the full rotation of the container 2A of the container exactly affects the removal point 24 at the labeling station 9 and removes a label by a rolling motion.
The gradient points of the corresponding curve sections of the tooth curves 17, 18, which become effective for the small bottle cross section exactly at the gluing point 8 and the removal point 24, cause such an angular velocity of the bottle 2A that its peripheral speed exactly at the named points 8 and 24 relative to the stationary stations 8 or 9 becomes zero. The same applies correspondingly to all bottle cross sections lying in the adjustment range of the angle β of the single turning program limited by the minimum and maximum bottle cross sections of the bottle 2A and 2B.
This single turning program is used at every angle Toothed curves 17, 18 of the roller stars 21 between the stations 8 and 9 always run completely, ie in all speed ranges, the decisive curve points corresponding to the respective bottle diameter always being effective at the points 8 and 24 mentioned.
The joint adjustment of the tooth curves 17, 18 takes place according to FIG. 1 after loosening a clamping screw 28 by means of a setting mark 29 for the angle β related to the bottle diameter by turning a cam carrier 31 by means of a torque support frame 32. The gluing device 8 and the labeling station 9 remain in any case at their intended fixed angular position with respect to the orbit of the container carrier 1 and are only adapted in their radial position to the respective bottle diameter.

Claims (7)

  1. Rotary container support for a container-handling machine, with a plurality of container receptacles which handle containers of differing cross-sections and which, with the container support rotating, as they pass through at least two work stations disposed along the circulation path of the container support are set in autorotation against the direction of rotation of the container support by two stationary tooth cams which are offset relative to one another in the peripheral direction and by roller stars which are coupled to the container receptacles and mesh with the tooth cams, characterised in that the tooth cams (17, 18) have a course which comprises one single rotation programme which is designed for a minimum and maximum container cross-section marked by end points (A, B or A₁, B₁) of specific cam portions, the tooth cams being infinitely adjustable in the peripheral direction (angle β) in such a way that in each case equal points (A, A₁ or B, B₁) of cam portions which correspond to one another are co-ordinated with specific positions on the work stations (8 or 9 respectively) which are disposed at a defined angular distance relative to one another.
  2. Container support according to Claim 1, characterised in that the first work station (8) is formed by a glueing device and the second work station (9) by a labelling station.
  3. Container support according to Claim 1 or 2, characterised in that the tooth cams (17, 18) are disposed at the top and concentrically with respect to a container support (1) which receives the containers (2) so that they are freely suspended.
  4. Container support according to one of Claims 1 to 3, characterised in that in co-ordination with the particular container cross-section the points (A, A₁, or B, B₁) on the cam portions always correspond to specific angular positions of the roller stars (21) relative to the work stations (8 or 9 respectively).
  5. Container support according to one of Claims 1 to 4, characterised in that in co-ordination with the particular container cross-section the points (A, A₁, or B, B₁) on the cam portions always correspond to specific peripheral speeds of the containers (2) rotating with the container receptacles (14) in the opposite direction to the container support (1) in such a way that in each case an outermost peripheral portion of a container passing through the work stations (8 or 9) in a specific angular position of the roller stars (21) is at a standstill.
  6. Container support according to one of Claims 1 to 5, characterised in that in each adjustment position (angle β) of the tooth cams (17, 18) the roller stars (21) between two work stations (8, 9) pass through at least one cam portion for the entire speed spectrum lying between the minimum and maximum container cross-section.
  7. Container support according to one of Claims 1 to 6, characterised in that the first work station (8) and the second work station (9) are disposed at such an angular distance (angle α) with respect to one another that the roller stars (21) carry out an autorotation about 360° with a container (2) of any cross-section in a range of angles of rotation (angle of rotation φ) of the container support (1) corresponding to this angular distance.
