Definitions
- the present invention relates to a lifting unit for raising and lowering a container in a container treatment plant, comprising a container holder for holding a container, a lifting device for raising and lowering the container holder, and a lock for locking the container holder in a predetermined position.
- the containers to be treated pass through a treatment angle along which they are pressed against a treatment element.
- a contact pressure force of a container against a treatment element is necessary in particular when forces act on the container during the treatment which could lead to the separation of the contact between the container and the treatment element. Such forces occur, for example, when the container is in contact with a filling valve and is biased by a gas.
- the weight of the filling product flowing into the container and the pressure fluctuations associated therewith result in forces which counteract the contact between the container and the filling element. Accordingly, the container must be pressed against the respective treatment element with a force that ensures contact between the container and the treatment element even when there are forces that counteract the contact.
- the lifting cylinder is able to move a container holder, such as a lifting plate or a neck-handling clamp, which holds the container up and down.
- a container holder such as a lifting plate or a neck-handling clamp
- the lifting cylinder brings the container with the Treatment organ in contact by raising the container holder towards the treatment organ.
- the container is pressed against the treatment element via the container holder.
- the lifting cylinder maintains the contact pressure via air pressure applied to the lifting cylinder.
- the lifting cylinder lowers the container holder, which releases the contact between the container and the container treatment element.
- a lifting device in the form of a pneumatic lifting cylinder is that, in order to raise and lower the container holder and to provide or maintain the contact pressure, air pressure must always be applied to the lifting cylinder and must be high enough to also provide the pressure required during the treatment Contact pressure provides.
- air pressure must always be applied to the lifting cylinder and must be high enough to also provide the pressure required during the treatment Contact pressure provides.
- providing high air pressure throughout the container treatment process results in high energy consumption.
- the entire hydraulic system must be designed for the high pressures to be expected and the high pressure must be provided over the entire treatment angle.
- the EP 2 792 634 A1 describes a lifting unit according to the preamble of claim 1 and having a position control system for an article handling machine and an associated method.
- a lifting unit for raising and lowering a container in a container treatment system which comprises a container holder for holding a container, a lifting device for raising and lowering the container holder, and a lock for locking the container holder in a predetermined position, the lock being magnetic .
- the magnetic locking makes it possible to hold the container holder, for example a lifting plate or a neck-handling clamp, in a predetermined lifting position. This holding of the lifting position is independent of the forces acting on the container or the container holder.
- the container holder is raised or lowered to the specified position by the lifting device and then magnetically locked in this position.
- the lifting device can be at least one lifting roller which is operatively connected to the container holder and which rolls on a lifting curve. Accordingly, the lifting cam guides the lifting roller or the container holder to the specified position, in which the container holder is then locked magnetically. After the container holder has been magnetically locked, there is no need for the lift roller to continue to roll on the lift cam. Thus, as the container holder traverses the treatment angle in which it is magnetically locked, it is not necessary for a lift cam to be provided. Furthermore, when a revolving lifting curve is provided, the friction and therefore also the energy to be expended for driving the rotary device can be reduced.
- the lifting device can be designed pneumatically.
- the lifting device has a pneumatic cylinder to which pressure can be applied in order to raise and lower the container holder. Once the container holder has reached the specified position, it is locked magnetically. This eliminates the need to maintain the high pressure applied to the lift cylinder while the canister holder traverses the treatment angle in which it is magnetically locked.
- the lifting device is provided by an electric motor, for example a linear motor, which enables the container holder to be raised and lowered. Once the container holder has reached the specified position, it can be magnetically locked in this position so that the electric motor can be switched off.
- an electric motor for example a linear motor
- the predetermined position of the container holder is, for example, a position in which a container carried by the container holder is pressed against a filling element, in particular a valve unit.
- the lifting device is required to bring the container holder to the specified position. In this position, the container holder can be locked magnetically, so that the lifting device is not required to hold the container holder in the specified position.
- the lock includes a magnet, preferably a permanent electromagnet, for locking and releasing a position of the container holder.
- a compact locking mechanism By using a magnet, a compact locking mechanism can be provided, which can be operated with comparatively little energy.
- the use of a permanent magnet for example, does not require the provision of energy to generate the magnetic field that enables locking.
- the permanent electromagnet is a permanent magnet which is coupled to an electromagnet. If there is no voltage on the electromagnet, the permanent magnet can fully develop its magnetic field and provides a maximum holding force for locking the container holder. If a voltage is applied to the electromagnet, the electromagnet generates a magnetic field which counteracts the magnetic field of the permanent magnet. Correspondingly, the electromagnet reduces the total magnetic field generated by the permanent magnet and the electromagnet and thereby the holding force emanating from the permanent magnet, so that the magnetic locking is released and the container holder is therefore unlocked or released.
- the reduction in the holding force of the permanent magnet caused by the electromagnet can be set such that a remaining, reduced holding force of the permanent magnet can be overcome via the weight of the container holder, so that the container holder can be unlocked or released.
- an armature preferably a ferromagnetic armature, is opposite the magnet and can be attracted by the magnet to magnetically lock the container holder.
- the armature When the container holder is in the locked state, the armature is attracted by the magnetic field which emanates from the magnet, in particular the permanent magnet.
- the armature and the magnet have two smooth contact surfaces running parallel to one another, so that they are in contact with one another in the locked state.
- the armature Due to the fact that the armature is ferromagnetic, the armature can spontaneously generate a magnetic field due to the magnetic field emanating from the magnet, in particular the permanent magnet experience magnetization. If the armature is not in the area of the magnetic field emanating from the magnet, in particular the permanent magnet, in the unlocked state, the armature is not magnetized.
- the magnet is arranged on a carrier plate of a filler carousel for transporting the container through a treatment angle or on a bearing for storing the container holder.
- the anchor is arranged on a bearing for supporting the container holder or a carrier plate of a filler carousel for transporting the container through a treatment angle.
- the bearing can be, for example, a bearing tube that has a longitudinal axis that is arranged concentrically to a guide. In order to enable a lifting movement of the container holder, the bearing tube can be moved along the guide.
- the anchor is arranged on the bearing, the anchor is connected to the container holder via the bearing, so that the anchor follows the lifting movements of the container holder.
- the magnetic lock is arranged on the carrier plate of a carousel, so that the armature can be moved relative to the magnetic lock together with the container holder. If the magnetic lock is arranged above the armature, the armature can be lifted by means of the lifting device until the magnetic field emanating from the magnetic lock, in particular the magnet, detects and attracts the armature. In this case, the dead weight of the container holder, the bearing and the armature counteract the attractive force of the magnetic lock. Accordingly, the dead weight of the container holder, the bearing and the armature can be used when unlocking or releasing the armature from the magnetic lock.
- the arrangement of the magnetic lock on the carrier plate of a carousel can facilitate an electrical connection to the magnetic lock, for example to provide an electromagnet.
- the magnetic lock follows the lifting movement of the container holder.
- the anchor is fixed and can be formed by the support plate.
- the carrier plate is made of ferromagnetic material, so that it can be magnetized spontaneously by the magnetic field emanating from the magnetic locking unit.
- a shock absorber is provided in parallel with the magnet and the armature to dampen the collision of the armature with the magnet.
- the shock absorber can be arranged on the carrier plate of a carousel or on the bearing.
- the shock absorber ensures that the armature does not damage the magnet upon impact or collision. The smaller the distance between the armature and the magnet, the greater the attractive force that emanates from the magnet. Accordingly, the armature is accelerated by the magnetic field emanating from the magnet, so that the armature moves toward the magnet at a critical speed, or vice versa.
- the damper makes it possible to reduce this speed or acceleration, which protects both the magnet and the armature.
- the armature and the magnet are arranged in series or next to one another with respect to a stroke direction. If the armature and the magnet are arranged in series with respect to the lifting direction, the attractive force acting on the armature from the magnet acts parallel to the lifting direction of the lifting unit. Correspondingly, the magnetic field can be used to support the lifting movement of the lifting unit in a predetermined position.
- the force of attraction acting on the armature from the magnet acts perpendicularly to the lifting direction of the lifting unit. This makes it possible for the armature to be detected by the magnetic field emanating from the magnet only after it has been brought to a predetermined position by the lifting unit.
- the lifting device has at least one lifting roller, which can be rolled on a lifting cam to release the locking device.
- the lifting cam on which the at least one lifting roller rolls, generates a lifting movement which separates the armature from the magnetic lock.
- the components of the lift curve and the at least a lifting roller are designed in such a way that they withstand the maximum holding force of the permanent magnet of the magnetic lock, which is 800 Newton, for example, or overcome it in order to separate the armature from the permanent magnet.
- the container holder and in particular the armature experience a lift which moves the armature out of the area of the permanent magnet's attractive force.
- the dead weight of the container holder, the bearing and the armature is carried by the lifting device, which is responsible for raising and lowering the container holder, so that the at least one lifting roller and the lifting cam are only provided for separating the connection between the armature and the magnet .
- a bolt preferably a ferromagnetic bolt, is also located opposite the magnet for mechanical locking of the container holder, the bolt being pretensionable via a bolt spring.
- the bolt locks the container holder in a predetermined position by clamping it or by pressing the bolt into a complementary bolt receptacle on the container holder.
- the bolt spring can hold the bolt in an unlocked position. If the magnet acts on the bolt, the bolt can be brought into a locked position by the magnetic field generated by the magnet. For example, the magnet can repel the bolt and press it towards the container holder in opposition to the spring force of the bolt spring. Alternatively, the magnet can exert an attractive force on the stud and pull the stud against the container holder in opposition to the spring force of the stud spring.
- the bolt spring ensures that the container holder is unlocked.
- a permanent electromagnet can be used in which the magnetic field of the electromagnet counteracts the magnetic field of the permanent magnet. When a voltage is applied to the electromagnet, the magnetic field of the permanent magnet can then be weakened or neutralized, so that the bolt spring moves the bolt away from the container holder into the unlocked position.
- the bolt spring can also push the bolt into the locked position.
- the magnet then serves to move the bolt into the unlocked position against the spring force of the bolt.
- a bearing for bearing the container holder and a guide for guiding the bearing are secured via an anti-twist device to prevent the lifting plate from twisting about the guide in a plane perpendicular to a lifting direction.
- the lifting unit and in particular the guide is subjected to a load in the form of moments of force. This can cause the lifting unit to twist around the guide. Such twisting is prevented by means of the twist lock.
- the anti-rotation device is preferably arranged on the bearing and has a guide unit which enables lifting movements of the lifting unit, in particular the bearing, relative to the anti-rotation device.
- the container holder is spring-mounted relative to the lifting device, preferably prestressed. This makes it possible that, in the magnetically locked state of the container holder, a pressing force of the container holder, by means of which the container holder presses a container against a treatment element, in particular a filling element, is provided.
- the springing of the container holder is preferably subject to a preload, which makes it possible to provide a predetermined contact pressure after the magnetic locking mechanism has locked the container holder in the predetermined position.
- the spring-loaded mounting or prestressing of the container holder makes it possible to compensate for tolerances in the height of the containers to be treated.
- the bearing is mounted on the guide by means of at least one plain bearing. Accordingly, the storage together with the container holder thereby be moved relative to the guide.
- the slide bearings enable the bearing or the container holder to be raised and lowered, with frictional forces which arise as a result of the bearing sliding on the guide being kept low.
- the guide is bolt-shaped, with the bearing being tubular and arranged concentrically with the guide. Accordingly, the storage can be attached to the guide and moved on this.
- the tubular bearing offers sufficient space on the outer peripheral surface for attaching the other components of the lifting unit, in particular the container holder, the armature or the magnetic lock and an anti-twist device.
- the container holder is a lifting plate or a neck-handling clamp for receiving a container.
- These container holders are suitable for common bottle types.
- a lifting plate is used to transport glass bottles or stable plastic bottles.
- a neck handling clamp is suitable, for example, for transporting plastic bottles made of PET or HDPE. Overall, such container holders represent reliable transport through the treatment angle of a rotary filler.

- the lifting disk rod 24 has an annular, circumferential projection 27 which is pressed against a shoulder of the tube 22 by means of a spring 26 inside the tube 22 .
- the spring 26 is, for example, a spiral spring which is located below the projection 27 is arranged around the lifting disc rod 24 .
- the spring 26 is enclosed within the tube 22 by means of a cap 28 at the lower end of the tube 22 .
- the spring 26 is supported on the cover 28 and prestresses the lifting plate rod 24 against the tube 22 .
- the bias is for example 500 Newtons. Alternatively, depending on the application, a smaller or larger preload force can be selected.
- the lifting plate 21 can be pressed down together with the lifting plate rod 24, whereby the spring 26 is compressed.
- the cover has a corresponding recess.
- the lifting plate 21, the lifting plate rod 24, the tube 22 and the cover 28 are made of stainless steel. Alternatively, other metals can also be used.
- FIG. 3 it can also be seen that the cover 28 is screwed to the tube 22 .
- An O-ring 29 is provided between the contact surfaces of the tube 22 and the lid 28 to seal the interior of the tube 22 from the environment.

- the arm 23 is screwed to the bearing 40 .
- the arm 23 can also be welded to the bearing 40 .
- the bearing 40 is tubular and is placed on the guide 30 in a concentrically displaceable manner.
- the displaceability of the bearing 40 on the guide 30 is made possible by slide bearings 42 which are each arranged at the ends of the tubular bearing 40 . These are preferably lubricant-free plain bearings.
- the bearing 40 is a turned and milled part made of stainless steel. Alternatively, the bearing 40 can also be made from a different metal.
- the guide 30 is in the form of a bolt and is connected at an upper end 34 via a thread 32 to the carrier plate 80 of a carousel.
- the guide 30 extends perpendicularly from the support plate 80 downwards.

- the magnet 72 is arranged on the underside of the carrier plate 80 and is opposite the armature 50 . If the lifting plate 21 is raised to a predetermined position by means of the lifting unit 60 , then the armature 50 is caught by a magnetic field emanating from the magnet 72 . As a result, the lifting plate 21 can be held or locked in the predetermined position.
- the in the figures 1 and 2 The magnet 72 shown has a holding force of 800 N, for example, when it comes into direct contact with the armature 50 . If a voltage is applied to the electromagnet coupled to the permanent magnet, the holding force of the magnet 70 is reduced to 10 N. Due to the weight of the armature 50 and the components connected to the armature 50, the contact between the magnet 72 and the armature 50 can then be resolved.
- FIG. 2 Also shown is that the magnet 72 is encased by a tubular sleeve 76 and sealed by a foil 78 disposed on the surface of the magnet 70 opposite the armature 50 to protect the magnet 72 from corrosion. Correspondingly, the magnet 72 does not come into contact with fluid that is used in the treatment of the container or the cleaning of the container treatment system, so that the tendency to corrosion can also be reduced here.

- the height profiles of the lower curve 600 and the upper curve 602 rise in parallel, so that the lifting unit is raised.
- the upper lift curve 602 is in particular needed when the lock cannot be unlocked. That is, in the event that the electromagnet fails and the holding force by which the permanent magnet attracts the armature cannot be reduced.
Description
Die vorliegende Erfindung betrifft eine Hubeinheit zum Anheben und Absenken eines Behälters in einer Behälterbehandlungsanlage, umfassend eine Behälterhalterung zum Halten eines Behälters, eine Hubeinrichtung zum Anheben und Absenken der Behälterhalterung, und eine Verriegelung zum Verriegeln der Behälterhalterung in einer vorgegebenen Position.The present invention relates to a lifting unit for raising and lowering a container in a container treatment plant, comprising a container holder for holding a container, a lifting device for raising and lowering the container holder, and a lock for locking the container holder in a predetermined position.
Während der Behälterbehandlung beispielsweise in Rundläuferfüllmaschinen durchlaufen zu behandelnde Behälter einen Behandlungswinkel, entlang welchem sie gegen ein Behandlungsorgan gepresst werden. Das Bereitstellen einer Anpresskraft eines Behälters gegen ein Behandlungsorgan ist insbesondere dann notwendig, wenn auf den Behälter während der Behandlung Kräfte einwirken, die zur Trennung des Kontakts zwischen dem Behälter und dem Behandlungsorgan führen könnten. Derartige Kräfte treten beispielsweise auf, wenn der Behälter mit einem Füllventil in Kontakt steht und durch ein Gas vorgespannt wird. Auch beim Befüllen des Behälters mit Füllprodukt kommt es durch das Eigengewicht des in den Behälter strömenden Füllprodukts sowie damit einhergehenden Druckschwankungen zu Kräften, welche dem Kontakt zwischen dem Behälter und dem Füllorgan entgegenwirken. Entsprechend muss der Behälter mit einer Kraft gegen das jeweilige Behandlungsorgan gepresst werden, welche den Kontakt zwischen dem Behälter und dem Behandlungsorgan auch beim Vorliegen von der Kontaktierung entgegenwirkenden Kräften sicherstellt.During container treatment, for example in rotary filling machines, the containers to be treated pass through a treatment angle along which they are pressed against a treatment element. The provision of a contact pressure force of a container against a treatment element is necessary in particular when forces act on the container during the treatment which could lead to the separation of the contact between the container and the treatment element. Such forces occur, for example, when the container is in contact with a filling valve and is biased by a gas. When the container is being filled with filling product, the weight of the filling product flowing into the container and the pressure fluctuations associated therewith result in forces which counteract the contact between the container and the filling element. Accordingly, the container must be pressed against the respective treatment element with a force that ensures contact between the container and the treatment element even when there are forces that counteract the contact.
Es ist bekannt, die nötige Anpresskraft über einen pneumatischen Hubzylinder bereitzustellen. Dabei ist der Hubzylinder in der Lage, eine Behälterhalterung, wie zum Beispiel einen Hubteller oder eine Neck-Handling-Klammer, welche den Behälter aufnimmt, auf und ab zubewegen. Während des Durchlaufens des Behandlungswinkels bringt der Hubzylinder den Behälter mit dem Behandlungsorgan in Kontakt, indem er die Behälterhalterung zum Behandlungsorgan hin anhebt. Der Behälter wird dabei über die Behälterhalterung an das Behandlungsorgan angepresst. Während einer anschließenden Behälterbehandlung, wie zum Beispiel einem Befüllvorgang, hält der Hubzylinder die Anpresskraft über einen am Hubzylinder anliegenden Luftdruck aufrecht. Ist der Behandlungsvorgang abgeschlossen, senkt der Hubzylinder die Behälterhalterung ab, wodurch der Kontakt zwischen Behälter und Behälterbehandlungsorgan gelöst wird.It is known to provide the necessary contact pressure via a pneumatic lifting cylinder. The lifting cylinder is able to move a container holder, such as a lifting plate or a neck-handling clamp, which holds the container up and down. During the passage through the treatment angle, the lifting cylinder brings the container with the Treatment organ in contact by raising the container holder towards the treatment organ. The container is pressed against the treatment element via the container holder. During a subsequent container treatment, such as a filling process, the lifting cylinder maintains the contact pressure via air pressure applied to the lifting cylinder. When the treatment process is complete, the lifting cylinder lowers the container holder, which releases the contact between the container and the container treatment element.
Nachteilig an einer Hubeinrichtung in Form eines pneumatischen Hubzylinders ist, dass zum Anheben und Absenken der Behälterhalterung sowie zur Bereitstellung beziehungsweise Aufrechterhaltung der Anpresskraft stets ein an dem Hubzylinder anliegender Luftdruck bereitgestellt werden muss, der so hoch sein muss, dass er auch den während der Behandlung notwendigen Anpressdruck bereitstellt. Die Bereitstellung eines hohen Luftdrucks während des gesamten Behälterbehandlungsvorgangs führt jedoch zu einem hohen Energieverbrauch. Weiterhin muss das gesamte hydraulische System für die zu erwartenden hohen Drücke ausgelegt sein und der hohe Druck über den gesamten Behandlungswinkel hinweg bereitgestellt werden.The disadvantage of a lifting device in the form of a pneumatic lifting cylinder is that, in order to raise and lower the container holder and to provide or maintain the contact pressure, air pressure must always be applied to the lifting cylinder and must be high enough to also provide the pressure required during the treatment Contact pressure provides. However, providing high air pressure throughout the container treatment process results in high energy consumption. Furthermore, the entire hydraulic system must be designed for the high pressures to be expected and the high pressure must be provided over the entire treatment angle.
Die
Ausgehend von dem bekannten Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine verbesserte Hubeinheit zum Anheben und Absenken eines Behälters in einer Behälterbehandlungsanlage bereitzustellen.Proceeding from the known state of the art, it is an object of the present invention to provide an improved lifting unit for raising and lowering a container in a container treatment plant.
Diese Aufgabe wird mittels einer Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is achieved by means of a device having the features of claim 1. Advantageous configurations result from the dependent claims.
Entsprechend wird eine Hubeinheit zum Anheben und Absenken eines Behälters in einer Behälterbehandlungsanlage angegeben, welche eine Behälterhalterung zum Halten eines Behälters, eine Hubeinrichtung zum Anheben und Absenken der Behälterhalterung, und eine Verriegelung zum Verriegeln der Behälterhalterung in einer vorgegebenen Position umfasst, wobei die Verriegelung magnetisch ist.Accordingly, a lifting unit for raising and lowering a container in a container treatment system is specified, which comprises a container holder for holding a container, a lifting device for raising and lowering the container holder, and a lock for locking the container holder in a predetermined position, the lock being magnetic .
Durch die magnetische Verriegelung ist es möglich, die Behälterhalterung, beispielsweise einen Hubteller oder eine Neck-Handling-Klammer, in einer vorgegebenen Hubposition zu halten. Dieses Halten der Hubposition ist dabei unabhängig von den auf den Behälter beziehungsweise die Behälterhalterung einwirkenden Kräften. Die Behälterhalterung wird dabei durch die Hubeinrichtung auf die vorgegebene Position angehoben oder abgesenkt und dann in dieser Position magnetisch verriegelt.The magnetic locking makes it possible to hold the container holder, for example a lifting plate or a neck-handling clamp, in a predetermined lifting position. This holding of the lifting position is independent of the forces acting on the container or the container holder. The container holder is raised or lowered to the specified position by the lifting device and then magnetically locked in this position.
Bei der Hubeinrichtung kann es sich um mindestens eine mit der Behälterhalterung wirkverbundene Hubrolle handeln, welche auf einer Hubkurve abrollt. Entsprechend führt die Hubkurve die Hubrolle beziehungsweise die Behälterhalterung auf die vorgegebene Position, auf welcher die Behälterhalterung dann magnetisch verriegelt wird. Nachdem die Behälterhalterung magnetisch verriegelt worden ist, ist es nicht erforderlich, dass die Hubrolle weiterhin auf der Hubkurve abrollt. Während die Behälterhalterung den Behandlungswinkel durchläuft, in welchem er magnetisch verriegelt ist, ist es somit nicht erforderlich, dass eine Hubkurve bereitgestellt wird. Weiterhin kann auch bei Bereitstellung einer umlaufenden Hubkurve die Reibung und daher auch die zum Antrieb der Rundläufervorrichtung aufzuwendende Energie reduziert werden.The lifting device can be at least one lifting roller which is operatively connected to the container holder and which rolls on a lifting curve. Accordingly, the lifting cam guides the lifting roller or the container holder to the specified position, in which the container holder is then locked magnetically. After the container holder has been magnetically locked, there is no need for the lift roller to continue to roll on the lift cam. Thus, as the container holder traverses the treatment angle in which it is magnetically locked, it is not necessary for a lift cam to be provided. Furthermore, when a revolving lifting curve is provided, the friction and therefore also the energy to be expended for driving the rotary device can be reduced.
Alternativ kann die Hubeinrichtung pneumatisch ausgeführt sein. Dabei weist die Hubeinrichtung einen Pneumatikzylinder auf, an welchem ein Druck angelegt werden kann, um die Behälterhalterung anzuheben und abzusenken. Hat die Behälterhalterung die vorgegebene Position erreicht, wird sie magnetisch verriegelt. Dadurch ist es nicht erforderlich, den an dem Hubzylinder anliegenden hohen Druck aufrecht zu erhalten, während die Behälterhalterung den Behandlungswinkel durchläuft, in welchem sie magnetisch verriegelt ist.Alternatively, the lifting device can be designed pneumatically. The lifting device has a pneumatic cylinder to which pressure can be applied in order to raise and lower the container holder. Once the container holder has reached the specified position, it is locked magnetically. This eliminates the need to maintain the high pressure applied to the lift cylinder while the canister holder traverses the treatment angle in which it is magnetically locked.
In einer weiteren Variante ist die Hubeinrichtung durch einen Elektromotor, beispielsweise einen Linearmotor, bereitgestellt, welcher ein Anheben und Absenken der Behälterhalterung ermöglicht. Hat die Behälterhalterung die vorgegebene Position erreicht, kann sie in dieser Position magnetisch verriegelt werden, so dass der Elektromotor abgeschaltet werden kann.In a further variant, the lifting device is provided by an electric motor, for example a linear motor, which enables the container holder to be raised and lowered. Once the container holder has reached the specified position, it can be magnetically locked in this position so that the electric motor can be switched off.
Die vorgegebene Position der Behälterhalterung ist beispielsweise eine Position, in welcher ein von der Behälterhalterung getragener Behälter gegen ein Füllorgan, insbesondere eine Ventileinheit, angepresst wird.The predetermined position of the container holder is, for example, a position in which a container carried by the container holder is pressed against a filling element, in particular a valve unit.
Insgesamt wird die Hubeinrichtung dazu benötigt, die Behälterhalterung auf die vorgegebene Position zu bringen. In dieser Position kann die Behälterhalterung magnetisch verriegelt werden, so dass die Hubeinrichtung nicht benötigt wird, um die Behälterhalterung in der vorgegebenen Position zu halten.Overall, the lifting device is required to bring the container holder to the specified position. In this position, the container holder can be locked magnetically, so that the lifting device is not required to hold the container holder in the specified position.
Die Verriegelung umfasst einen Magneten, bevorzugt einen Permanent-Elektromagnet, zum Feststellen und Lösen einer Position der Behälterhalterung.The lock includes a magnet, preferably a permanent electromagnet, for locking and releasing a position of the container holder.
Durch die Verwendung eines Magneten kann eine kompakte Verriegelung bereitgestellt werden, welche vergleichsweise energiearm betrieben werden kann. Die Verwendung eines Permanentmagneten bedarf beispielsweise keiner Bereitstellung von Energie zur Erzeugung des Magnetfelds, welches die Verriegelung ermöglicht.By using a magnet, a compact locking mechanism can be provided, which can be operated with comparatively little energy. The use of a permanent magnet, for example, does not require the provision of energy to generate the magnetic field that enables locking.
Durch die Verwendung eines Permanent-Elektromagnets wird eine Verriegelung bereitgestellt, welche die Position der Behälterhalterung sowohl verriegeln als auch lösen kann. Bei dem Permanent-Elektromagnet handelt es sich um einen Permanentmagneten, welcher mit einem Elektromagnetenen gekoppelt ist. Liegt an dem Elektromagneten keine Spannung an, so kann der Permanentmagnet sein Magnetfeld vollständig entfalten und stellt eine maximale Haltekraft zum Verriegeln der Behälterhalterung bereit. Wird an den Elektromagnet eine Spannung angelegt, erzeugt der Elektromagnet ein Magnetfeld, welches dem Magnetfeld des Permanentmagnets entgegenwirkt. Entsprechend reduziert der Elektromagnet das von Permanentmagnet und Elektromagnet erzeugte Gesamtmagnetfeld und dabei die von dem Permanentmagnet ausgehende Haltekraft, so dass die magnetische Verriegelung gelöst und daher die Behälterhalterung entriegelt beziehungsweise gelöst wird. Dabei kann die durch den Elektromagnet hervorgerufene Reduktion der Haltekraft des Permanentmagnets derart festgelegt sein, dass eine verbleibende, reduzierte Haltekraft des Permanentmagnets über die Gewichtskraft der Behälterhalterung überwunden werden kann, so dass die Behälterhalterung entriegelt beziehungsweise gelöst werden kann.Through the use of a permanent electromagnet, a lock is provided which can both lock and unlock the position of the container holder. The permanent electromagnet is a permanent magnet which is coupled to an electromagnet. If there is no voltage on the electromagnet, the permanent magnet can fully develop its magnetic field and provides a maximum holding force for locking the container holder. If a voltage is applied to the electromagnet, the electromagnet generates a magnetic field which counteracts the magnetic field of the permanent magnet. Correspondingly, the electromagnet reduces the total magnetic field generated by the permanent magnet and the electromagnet and thereby the holding force emanating from the permanent magnet, so that the magnetic locking is released and the container holder is therefore unlocked or released. The reduction in the holding force of the permanent magnet caused by the electromagnet can be set such that a remaining, reduced holding force of the permanent magnet can be overcome via the weight of the container holder, so that the container holder can be unlocked or released.
Erfindungsgemäß liegt dem Magnet ein Anker, bevorzugt ein ferromagnetischer Anker, gegenüber, welcher zum magnetischen Verriegeln der Behälterhalterung von dem Magneten anziehbar ist.According to the invention, an armature, preferably a ferromagnetic armature, is opposite the magnet and can be attracted by the magnet to magnetically lock the container holder.
Im verriegelten Zustand der Behälterhalterung wird der Anker durch das Magnetfeld, welches von dem Magnet, insbesondere dem Permanentmagnet, ausgeht, angezogen. Dabei weisen der Anker und der Magnet zwei glatte, parallel zueinander verlaufende Kontaktoberflächen auf, so die im verriegelten Zustand miteinander in Kontakt stehen.When the container holder is in the locked state, the armature is attracted by the magnetic field which emanates from the magnet, in particular the permanent magnet. The armature and the magnet have two smooth contact surfaces running parallel to one another, so that they are in contact with one another in the locked state.
Dadurch, dass der Anker ferromagnetisch ausgebildet ist, kann der Anker durch das von dem Magnet, insbesondere dem Permanentmagnet, ausgehende Magnetfeld eine spontane Magnetisierung erfahren. Befindet sich der Anker im entriegelten Zustand nicht im Bereich des von dem Magnet, insbesondere dem Permanentmagnet, ausgehenden Magnetfelds, weist der Anker keine Magnetisierung auf.Due to the fact that the armature is ferromagnetic, the armature can spontaneously generate a magnetic field due to the magnetic field emanating from the magnet, in particular the permanent magnet experience magnetization. If the armature is not in the area of the magnetic field emanating from the magnet, in particular the permanent magnet, in the unlocked state, the armature is not magnetized.
In einer weiter bevorzugten Weiterbildung ist der Magnet an einer Trägerplatte eines Füllerkarussells zum Transport des Behälters durch einen Behandlungswinkel oder an einer Lagerung zum Lagern der Behälterhalterung angeordnet.In a further preferred development, the magnet is arranged on a carrier plate of a filler carousel for transporting the container through a treatment angle or on a bearing for storing the container holder.
In einer bevorzugten Weiterbildung ist der Anker an einer Lagerung zum Lagern der Behälterhalterung oder einer Trägerplatte eines Füllerkarussells zum Transport des Behälters durch einen Behandlungswinkel angeordnet.In a preferred development, the anchor is arranged on a bearing for supporting the container holder or a carrier plate of a filler carousel for transporting the container through a treatment angle.
Bei der Lagerung kann es sich beispielsweise um ein Lagerrohr handeln, das eine Längsachse aufweist, die konzentrisch zu einer Führung angeordnet ist. Um eine Hubbewegung der Behälterhalterung zu ermöglichen, kann das Lagerrohr entlang der Führung verschoben werden.The bearing can be, for example, a bearing tube that has a longitudinal axis that is arranged concentrically to a guide. In order to enable a lifting movement of the container holder, the bearing tube can be moved along the guide.
Ist der Anker an der Lagerung angeordnet, ist der Anker über die Lagerung mit der Behälterhalterung verbunden, so dass der Anker den Hubbewegungen der Behälterhalterung folgt. Entsprechend ist die magnetische Verriegelung an der Trägerplatte eines Karussells angeordnet, so dass der Anker gemeinsam mit der Behälterhalterung relativ zu der magnetischen Verriegelung bewegbar ist. Ist die magnetische Verriegelung oberhalb des Ankers angeordnet, kann der Anker mittels der Hubeinrichtung angehoben werden, bis das von der magnetischen Verriegelung, insbesondere dem Magnet, ausgehende Magnetfeld den Anker erfasst und anzieht. In diesem Fall wirken das Eigengewicht der Behälterhalterung, der Lagerung und des Ankers der Anziehungskraft der magnetischen Verriegelung entgegen. Entsprechend kann das Eigengewicht der Behälterhalterung, des Lagers und des Ankers bei der Entriegelung beziehungsweise beim Lösen des Ankers von der magnetischen Verriegelung genutzt werden.If the anchor is arranged on the bearing, the anchor is connected to the container holder via the bearing, so that the anchor follows the lifting movements of the container holder. Correspondingly, the magnetic lock is arranged on the carrier plate of a carousel, so that the armature can be moved relative to the magnetic lock together with the container holder. If the magnetic lock is arranged above the armature, the armature can be lifted by means of the lifting device until the magnetic field emanating from the magnetic lock, in particular the magnet, detects and attracts the armature. In this case, the dead weight of the container holder, the bearing and the armature counteract the attractive force of the magnetic lock. Accordingly, the dead weight of the container holder, the bearing and the armature can be used when unlocking or releasing the armature from the magnetic lock.
Darüber hinaus kann durch die Anordnung der magnetischen Verriegelung an der Trägerplatte eines Karussells ein elektrischer Anschluss an die magnetische Verriegelung, beispielsweise zur Bereitstellung eines Elektromagnets, begünstigt werden.In addition, the arrangement of the magnetic lock on the carrier plate of a carousel can facilitate an electrical connection to the magnetic lock, for example to provide an electromagnet.
Ist der Anker an der Trägerplatte eines Karussells und die magnetische Verriegelung an der Lagerung angeordnet, folgt die magnetische Verriegelung der Hubbewegung der Behälterhalterung.If the armature is arranged on the carrier plate of a carousel and the magnetic lock is arranged on the bearing, the magnetic lock follows the lifting movement of the container holder.
Der Anker steht fest und kann durch die Trägerplatte ausgebildet sein. In diesem Fall besteht die Trägerplatte aus ferromagnetischem Material, so dass sie durch das von der magnetischen Verriegelungseinheit ausgehende Magnetfeld spontan magnetisiert werden kann.The anchor is fixed and can be formed by the support plate. In this case, the carrier plate is made of ferromagnetic material, so that it can be magnetized spontaneously by the magnetic field emanating from the magnetic locking unit.
In einer weiter bevorzugten Weiterbildung ist parallel zu dem Magnet und dem Anker ein Stoßdämpfer zum Dämpfen des Aneinanderstoßens des Ankers mit dem Magnet bereitgestellt. Dabei kann der Stoßdämpfer an der Trägerplatte eines Karussells oder an der Lagerung angeordnet sein. Der Stoßdämpfer stellt sicher, dass der Anker den Magnet beim Aufprall beziehungsweise Aneinanderstoßen nicht beschädigt. Je kleiner der Abstand zwischen dem Anker und dem Magnet ist, desto größer ist die Anziehungskraft, welche von dem Magnet ausgeht. Entsprechend erfährt der Anker durch das von dem Magnet ausgehende Magnetfeld eine Beschleunigung, so dass sich der Anker mit einer kritischen Geschwindigkeit auf den Magnet zu bewegt oder umgekehrt. Der Dämpfer ermöglicht es, diese Geschwindigkeit beziehungsweise Beschleunigung zu reduzieren, wodurch sowohl der Magnet als auch der Anker geschont werden.In a further preferred development, a shock absorber is provided in parallel with the magnet and the armature to dampen the collision of the armature with the magnet. The shock absorber can be arranged on the carrier plate of a carousel or on the bearing. The shock absorber ensures that the armature does not damage the magnet upon impact or collision. The smaller the distance between the armature and the magnet, the greater the attractive force that emanates from the magnet. Accordingly, the armature is accelerated by the magnetic field emanating from the magnet, so that the armature moves toward the magnet at a critical speed, or vice versa. The damper makes it possible to reduce this speed or acceleration, which protects both the magnet and the armature.
In einer weiteren Ausgestaltung sind der Anker und der Magnet in Bezug auf eine Hubrichtung in Reihe, beziehungsweise nebeneinander, angeordnet. Sind der Anker und der Magnet in Bezug auf die Hubrichtung in Reihe angeordnet, wirkt die von dem Magnet auf den Anker wirkende Anziehungskraft parallel zur Hubrichtung der Hubeinheit. Entsprechend kann das Magnetfeld zur Unterstützung der Hubbewegung der Hubeinheit in eine vorgegebene Position genutzt werden.In a further embodiment, the armature and the magnet are arranged in series or next to one another with respect to a stroke direction. If the armature and the magnet are arranged in series with respect to the lifting direction, the attractive force acting on the armature from the magnet acts parallel to the lifting direction of the lifting unit. Correspondingly, the magnetic field can be used to support the lifting movement of the lifting unit in a predetermined position.
Sind der Anker und der Magnet in Bezug auf die Hubrichtung nebeneinander angeordnet, wirkt die von dem Magnet auf den Anker wirkende Anziehungskraft senkrecht zur Hubrichtung der Hubeinheit. Dadurch ist es möglich, dass der Anker erst von dem von dem Magnet ausgehenden Magnetfeld erfasst wird, wenn er durch die Hubeinheit auf eine vorgegebene Position gebracht worden ist.If the armature and the magnet are arranged next to one another with respect to the lifting direction, the force of attraction acting on the armature from the magnet acts perpendicularly to the lifting direction of the lifting unit. This makes it possible for the armature to be detected by the magnetic field emanating from the magnet only after it has been brought to a predetermined position by the lifting unit.
In einer weiter bevorzugten Ausführungsform weist die Hubeinrichtung mindestens eine Hubrolle auf, welche auf einer Hubkurve zum Trennen der Verriegelung abrollbar ist.In a further preferred embodiment, the lifting device has at least one lifting roller, which can be rolled on a lifting cam to release the locking device.
Dadurch kann sichergestellt werden, dass die Behälterhalterung auch denn entriegelt werden kann, wenn der Elektromagnet der magnetischen Verriegelung ausfällt. Entsprechend erzeugt die Hubkurve, auf welcher die mindestens eine Hubrolle abrollt, eine Hubbewegung, welche den Anker von der magnetischen Verriegelung trennt. Die Komponenten der Hubkurve und der mindestens einen Hubrolle sind dabei derart ausgelegt, dass sie der maximalen Haltekraft des Permanentmagnets der magnetischen Verriegelung, welche beispielsweise 800 Newton beträgt, standhalten beziehungsweise diese überwinden, um den Anker von dem Permanentmagneten zu trennen.This can ensure that the container holder can be unlocked even if the electromagnet of the magnetic lock fails. Correspondingly, the lifting cam, on which the at least one lifting roller rolls, generates a lifting movement which separates the armature from the magnetic lock. The components of the lift curve and the at least a lifting roller are designed in such a way that they withstand the maximum holding force of the permanent magnet of the magnetic lock, which is 800 Newton, for example, or overcome it in order to separate the armature from the permanent magnet.
Durch das Abrollen der mindestens einen Hubrolle auf der Hubkurve erfahren die Behälterhalterung und insbesondere der Anker einen Hub, welcher den Anker aus dem Bereich der Anziehungskraft des Permanentmagnets befördert. Das Eigengewicht der Behälterhalterung, des Lagers und des Ankers wird von der Hubeinrichtung, welche für das Anheben und Absenken der Behälterhalterung verantwortlich ist, getragen, so dass die mindestens eine Hubrolle und die Hubkurve lediglich zum Trennen der Verbindung zwischen dem Anker und dem Magnet bereitgestellt sind.As a result of the at least one lifting roller rolling on the lifting curve, the container holder and in particular the armature experience a lift which moves the armature out of the area of the permanent magnet's attractive force. The dead weight of the container holder, the bearing and the armature is carried by the lifting device, which is responsible for raising and lowering the container holder, so that the at least one lifting roller and the lifting cam are only provided for separating the connection between the armature and the magnet .
In einer Weiterbildung liegt dem Magnet außerdem ein Bolzen, bevorzugt ein ferromagnetischer Bolzen, zur mechanischen Verriegelung der Behälterhalterung gegenüber, wobei der Bolzen über eine Bolzenfeder vorspannbar ist.In a further development, a bolt, preferably a ferromagnetic bolt, is also located opposite the magnet for mechanical locking of the container holder, the bolt being pretensionable via a bolt spring.
Dabei verriegelt der Bolzen die Behälterhalterung in einer vorgegebenen Position, indem er diese festklemmt oder der Bolzen in eine komplementäre Bolzenaufnahme an der Behälterhalterung gedrückt wird. Beispielsweise kann die Bolzenfeder den Bolzen in einer entriegelten Position halten. Wirkt der Magnet auf den Bolzen, kann der Bolzen durch das von dem Magnet erzeugte Magnetfeld in eine verriegelte Position gebracht werden. Beispielsweise kann der Magnet den Bolzen abstoßen und entgegengesetzt der Federkraft der Bolzenfeder hin zu der Behälterhalterung drücken. Alternativ kann der Magnet eine Anziehungskraft auf den Bolzen ausüben und den Bolzen entgegengesetzt der Federkraft der Bolzenfeder an die Behälterhalterung ziehen.The bolt locks the container holder in a predetermined position by clamping it or by pressing the bolt into a complementary bolt receptacle on the container holder. For example, the bolt spring can hold the bolt in an unlocked position. If the magnet acts on the bolt, the bolt can be brought into a locked position by the magnetic field generated by the magnet. For example, the magnet can repel the bolt and press it towards the container holder in opposition to the spring force of the bolt spring. Alternatively, the magnet can exert an attractive force on the stud and pull the stud against the container holder in opposition to the spring force of the stud spring.
Wird das von dem Magnet ausgehende Magnetfeld unterbrochen, sorgt die Bolzenfeder für eine Entriegelung der Behälterhalterung. Beispielsweise kann ein Permanent-Elektromagnet verwendet werden, bei welchem das Magnetfeld des Elektromagnets dem Magnetfeld des Permanentmagnets entgegenwirkt. Beim Anlegen einer Spannung an den Elektromagnet kann dann das Magnetfeld des Permanentmagnet geschwächt oder neutralisiert werden, so dass die Bolzenfeder den Bolzen von der Behälterhalterung weg in die entriegelter Position bewegt.If the magnetic field emanating from the magnet is interrupted, the bolt spring ensures that the container holder is unlocked. For example, a permanent electromagnet can be used in which the magnetic field of the electromagnet counteracts the magnetic field of the permanent magnet. When a voltage is applied to the electromagnet, the magnetic field of the permanent magnet can then be weakened or neutralized, so that the bolt spring moves the bolt away from the container holder into the unlocked position.
Alternativ kann die Bolzenfeder den Bolzen auch in die verriegelte Position drücken. In diesem Fall dient der Magnet dann dazu, den Bolzen entgegen der Bolzenfederkraft in die entriegelte Position zu bewegen.Alternatively, the bolt spring can also push the bolt into the locked position. In this case, the magnet then serves to move the bolt into the unlocked position against the spring force of the bolt.
In einer weiteren Ausgestaltung sind eine Lagerung zum Lagern der Behälterhalterung und eine Führung zum Führen der Lagerung über eine Verdrehsicherung zum Vermeiden eines Verdrehens des Hubtellers um die Führung in einer Ebene senkrecht zu einer Hubrichtung gesichert.In a further embodiment, a bearing for bearing the container holder and a guide for guiding the bearing are secured via an anti-twist device to prevent the lifting plate from twisting about the guide in a plane perpendicular to a lifting direction.
Durch die Interaktion der Hubeinheit mit anderen Komponenten, wie beispielsweise einer Hubkurve, erfährt die Hubeinheit und insbesondere die Führung eine Belastung in Form von Kraftmomenten. Dies kann dazu führen, dass sich die Hubeinheit um die Führung verdreht. Eine solche Verdrehung wird mittels der Verdrehsicherung unterbunden. Dabei ist die Verdrehsicherung bevorzugt an dem Lager angeordnet und weist eine Führungseinheit auf, welche Hubbewegungen der Hubeinheit, insbesondere des Lagers, relativ zur Verdrehsicherung ermöglicht.Due to the interaction of the lifting unit with other components, such as a lifting curve, the lifting unit and in particular the guide is subjected to a load in the form of moments of force. This can cause the lifting unit to twist around the guide. Such twisting is prevented by means of the twist lock. In this case, the anti-rotation device is preferably arranged on the bearing and has a guide unit which enables lifting movements of the lifting unit, in particular the bearing, relative to the anti-rotation device.
In einer weiter bevorzugten Ausgestaltung ist die Behälterhalterung gegenüber der Hubeinrichtung gefedert gelagert, bevorzugt vorgespannt. Dadurch wird ermöglicht, dass im magnetisch verriegelten Zustand der Behälterhalterung eine Anpresskraft der Behälterhalterung, mittels welcher die Behälterhalterung einen Behälter gegen ein Behandlungsorgan, insbesondere ein Füllorgan, drückt, bereitgestellt wird. Dabei unterliegt die Federung der Behälterhalterung bevorzugt einer Vorspannung, welche es ermöglicht, eine vorgegebene Anpresskraft bereitzustellen, nachdem die magnetische Verriegelung die Behälterhalterung in der vorgegebenen Position verriegelt hat.In a further preferred embodiment, the container holder is spring-mounted relative to the lifting device, preferably prestressed. This makes it possible that, in the magnetically locked state of the container holder, a pressing force of the container holder, by means of which the container holder presses a container against a treatment element, in particular a filling element, is provided. In this case, the springing of the container holder is preferably subject to a preload, which makes it possible to provide a predetermined contact pressure after the magnetic locking mechanism has locked the container holder in the predetermined position.
Darüber hinaus ermöglicht die gefederte Lagerung beziehungsweise Vorspannung der Behälterhalterung, dass Toleranzen der Höhe der zu behandelnden Behälter ausgeglichen werden können.In addition, the spring-loaded mounting or prestressing of the container holder makes it possible to compensate for tolerances in the height of the containers to be treated.
Insgesamt bedarf es nach der magnetischen Verriegelung der Behälterhalterung lediglich die von der gefederten Lagerung der Behälterhalterung ausgehende Vorspannkraft, um eine vorgegebene Anpresskraft bereitzustellen. Der energetische Aufwand zur Bereitstellung beziehungsweise zum Halten der Anpresskraft ist im Vergleich zu den bekannten Lösungen sehr gering.All in all, after the magnetic locking of the container holder, all that is required is the prestressing force emanating from the spring-loaded mounting of the container holder in order to provide a predetermined contact pressure. The expenditure of energy to provide or to maintain the contact pressure is very low compared to the known solutions.
In einer weiter bevorzugten Weiterbildung ist die Lagerung mittels mindestens einem Gleitlager auf der Führung gelagert. Entsprechend kann die Lagerung gemeinsam mit der Behälterhalterung dadurch relativ zu der Führung bewegt werden. Die Gleitlager ermöglichen ein Anheben und Absenken des Lagers beziehungsweise der Behälterhalterung, wobei Reibungskräfte, welche durch das Gleiten des Lagers auf der Führung entstehen, gering gehalten werden.In a further preferred development, the bearing is mounted on the guide by means of at least one plain bearing. Accordingly, the storage together with the container holder thereby be moved relative to the guide. The slide bearings enable the bearing or the container holder to be raised and lowered, with frictional forces which arise as a result of the bearing sliding on the guide being kept low.
In einer weiteren Ausführungsform ist die Führung bolzenförmig, wobei die Lagerung rohrförmig ist und konzentrisch zur Führung angeordnet ist. Entsprechend kann die Lagerung auf die Führung aufgesteckt und auf dieser verschoben werden. Die rohrförmige Lagerung bietet dabei ausreichend Platz auf der äußeren Umfangsoberfläche zum Anbringen der weiteren Komponenten der Hubeinheit, insbesondere der Behälterhalterung, dem Anker oder der magnetischen Verriegelung und einer Verdrehsicherung.In a further embodiment, the guide is bolt-shaped, with the bearing being tubular and arranged concentrically with the guide. Accordingly, the storage can be attached to the guide and moved on this. The tubular bearing offers sufficient space on the outer peripheral surface for attaching the other components of the lifting unit, in particular the container holder, the armature or the magnetic lock and an anti-twist device.
In einer bevorzugten Weiterbildung ist die Behälterhalterung ein Hubteller oder eine Neck-Handling-Klammer zum Aufnehmen eines Behälters. Diese Behälterhalterungen sind für gängige Flaschentypen geeignet. So kommt ein Hubteller beispielsweise zum Transportieren von Glasflaschen oder stabilen Kunststoffflaschen zum Einsatz. Eine Neck-Handling-Klammer eignet sich beispielsweise für den Transport von Kunststoffflaschen aus PET oder HDPE. Insgesamt stellen derartige Behälterhalterungen einen zuverlässigen Transport durch den Behandlungswinkel eines Rundläuferfüllers hindurch dar.In a preferred development, the container holder is a lifting plate or a neck-handling clamp for receiving a container. These container holders are suitable for common bottle types. For example, a lifting plate is used to transport glass bottles or stable plastic bottles. A neck handling clamp is suitable, for example, for transporting plastic bottles made of PET or HDPE. Overall, such container holders represent reliable transport through the treatment angle of a rotary filler.

Die Hubtellerstange 24 weist einen ringförmigen, umlaufenden Vorsprung 27 auf, welcher mittels einer Feder 26 im Inneren des Rohrs 22 gegen einen Absatz des Rohrs 22 gedrückt wird. Bei der Feder 26 handelt es sich beispielsweise um eine Spiralfeder, welche unterhalb des Vorsprungs 27 um die Hubtellerstange 24 angeordnet ist. Die Feder 26 ist mittels eines Deckels 28 am unteren Ende des Rohrs 22 in dem Rohr 22 eingeschlossen. Dabei stützt sich die Feder 26 auf dem Deckel 28 ab und spannt die Hubtellerstange 24 gegen das Rohr 22 vor. Die Vorspannung beträgt beispielsweise 500 Newton. Alternativ kann je nach Anwendungsfall auch eine kleinere oder größere Vorspannungskraft gewählt werden.The
Geht während eines Behandlungsvorgangs von einem Behälter eine Kraft auf den Hubteller 21 aus, welche beispielsweise auf fertigungsbedingte Abweichungen des Behältermaßes zurückzuführen ist, kann der Hubteller 21 gemeinsam mit der Hubtellerstange 24 nach unten gedrückt werden, wodurch die Feder 26 zusammengedrückt wird. Um zu vermeiden, dass die Hubtellerstange 24 den Deckel 28 berührt, weist dieser eine entsprechende Aussparung auf. Der Hubteller 21, die Hubtellerstange 24, das Rohr 22 und der Deckel 28 sind aus Edelstahl gefertigt. Alternativ können auch andere Metalle zum Einsatz kommen.If, during a treatment process, a container exerts a force on the lifting

Die Aufnahme 52 erstreckt sich senkrecht von einer Umfangsoberfläche der rohrförmigen Lagerung 40 aus. Auf die Oberseite der Aufnahme 52 ist eine Eisenplatte, welche einen Anker 50 bildet, angeschraubt. Alternativ kann der Anker 50 auch ein anderes ferromagnetisches Material, wie zum Beispiel Nickel oder Kobalt, aufweisen.At an
Der Anker 50 kann über eine Verriegelung 70 an der Trägerplatte 80 fixiert werden. Die Verriegelung 70 weist einen Magneten 72 auf, welcher hier in Form eines Permanent-Elektromagnets ausgebildet ist. Der Permanent-Elektromagnet besteht aus einem Permanentmagnet, welcher mit einem Elektromagneten gekoppelt ist. Der Magnet 72 ist an der Unterseite der Trägerplatte 80 angeordnet und liegt dem Anker 50 gegenüber. Wird der Hubteller 21 mittels der Hubeinheit 60 auf eine vorgegebene Position angehoben, so wird der Anker 50 von einem von dem Magnet 72 ausgehenden Magnetfeld erfasst. Dadurch kann der Hubteller 21 in der vorgegebenen Position gehalten beziehungsweise verriegelt werden.The
