The interchangeable container has a rotor of the metering pump, where a pipe coupling is provided between the interchangeable container and the beverage machine for connection of a line of the beverage or liquid additives and a drive coupling for the mechanical coupling of the rotor to a drive motor of the beverage machine. An independent claim is included for an interchangeable container liquid beverage additives for use in a vending machine.

Description

  • The present invention relates to a beverage machine according to the preamble of claim 1.
  • State of the art:
  • Commercially available beverage machines are known, especially for the preparation of hot drinks. As a rule, a beverage base, such as soup, cocoa coffee powder or the like, is mixed and / or brewed in a processing unit of the machine with hot water and / or steam.
  • Furthermore, beverage machines in the form of fully automatic coffee machines are known in which ground coffee is supplied from coffee beans stored in a corresponding container directly before brewing to a brewing unit intended for the preparation of coffee and brewed by means of pressurized steam to the coffee delivered by the coffee machine.
  • In beverage machines, a beverage concentrate is often mixed with a base liquid. Such a device is for example in the document DE 3940375 A1 or in the publication DE 3709155 C2 described.
  • Furthermore, metering pumps for adding liquids in beverage machines have become known in various publications, for example in the DE 10 2005 024 059 A1 . EP 1803934 A1 . EP 1863723 B1 and DE 3709161 C2 ,
  • Object and advantages of the invention:
  • The present invention has for its object to improve a beverage machine according to the introductory prior art.
  • This object is achieved according to a first aspect of the invention starting from a beverage machine according to the preamble of claim 1 by its characterizing features.
  • In the dependent claims advantageous and expedient developments are given.
  • Accordingly, the present invention relates to a beverage machine with a swap body for storing at least one liquid beverage additive, such as a flavoring, a nutritional supplement (vitamins, minerals, etc.) or the like, wherein the swap body comprises at least one rotor of the metering pump, wherein a line coupling between the Interchangeable container and the beverage machine for connecting the line of liquid or liquid beverage additives and a drive coupling for mechanical coupling of the rotor is provided with a drive motor of the beverage machine.
  • A swap body designed in this way simplifies the refilling process with the liquid beverage additive. He has the advantage that those parts of the metering device, which come into direct contact with the beverage additive, can be integrated into the swap body. This can thus be filled and then completely closed.
  • Such a closed swap container has the advantage for the user that he only needs to remove it from a package and exchange it with an empty swap body located in the beverage machine. Due to this completed embodiment, any contact with the liquid beverage additive stored in the swap body can be avoided in a user-friendly and easy-to-handle manner.
  • According to the invention, the replaceable swap body comprises at least part of a metering pump for the beverage additive. This is particularly advantageous with respect to an externally completed component construction, whereby, as described above, an uncomplicated and clean container exchange can be made possible.
  • Furthermore, the beverage machine according to the invention is provided with a line coupling between the swap body and the beverage machine for coupling a line for or the beverage additives and with a drive coupling for mechanical coupling of a drive of the rotor of the metering pump. The mechanical coupling of a pump drive via a rotary motion is easier to implement than for example via a plunger, especially with regard to the interchangeability of the interchangeable container.
  • This allows on the one hand a continuous liquid line and thus the inventive supply in the beverage additive in conjunction with a swap body and also the possibility to provide the drive for the metering pump outside of the swap body on the machine side. It is of particular importance in view of the fact that an at least partially integrated into the liquid container liquid pump is replaced with the swap body. The drive motor, however, can remain on the machine side, whereby the effort is reduced on the part of the interchangeable container.
  • Preferably, the line coupling for the line of beverage additive is formed so that it is fixed during operation. This reduces the design effort and preserves the tightness of the cleaner line.
  • In addition, the metering pump is preferably configured such that the drive motor to be coupled to the rotor is offset and / or angled relative to the axis of the pump rotor or its drive coupling. In particular, when the drive motor is not aligned with the pump rotor, in this case a space-saving arrangement of the drive motor can be provided on the machine side. This is particularly advantageous in the bottom area of a swap body in which the volume should be as completely as possible usable for the intake of beverage additives.
  • Furthermore, it is advantageous if the liquid connection of the interchangeable container is arranged offset relative to the axis of the pump rotor of the metering pump. On the one hand, this makes the fixed configuration of the first coupling for connecting the liquid line easier. On the other hand, this also makes an overall flatter design in the bottom area of the swap body possible.
  • In a specific embodiment, this is at least one. Gear element provided for bridging an offset and / or an angle between the rotor or the drive clutch and the drive motor of the metering pump. By using such a transmission element, such as a gear or the like, a possibility is given to realize the flat design described at the bottom of the interchangeable container at spaced couplings for the mechanical drive of the metering pump on the one hand and for the liquid cleaning line on the other.
  • In addition, a transmission element can also serve as a translation or reduction or reduction means, for example, to use a lower-power or slower engine. Here are all possible transmission elements in question, for example, a belt drive or the like could be provided.
  • In a particularly compact and thus space-saving design also a fixed cleaner line coaxial with a rotating drive or transmission element, z. B. arranged a gear.
  • In a preferred embodiment, the metering unit may have a metering element designed to be both rotationally and axially movable. In the case of a pump, this may be, for example, a pump piston which, in addition to a stroke movement along its longitudinal axis, can also perform a rotary movement. To control its axial position and / or its angular position with respect to a rotational movement about its longitudinal axis may be provided in a further advantageous manner, a backdrop or slide control. For this purpose, for example with a rotational movement impressed on the piston, preferably via a corresponding coupling element, a positively driven axial piston movement can be accomplished by driving off a control cam, by means of a control cam formed on the piston, to generate a delivery stroke.
  • It is also conceivable, however, a reverse drive mode, in the way that the piston is coupled with a him impressing his axial strokes drive unit and it is forcibly guided according to its axial position in the delivery cylinder, for example, also via a link control. Such a link control has the advantage that each position point along an axial movement exactly a corresponding rotation angle can be assigned, or vice versa.
  • To generate a specific delivery volume per delivery stroke can be formed between piston and cylinder sealing means in such a way that they are on the one hand in plan view around the piston, or in the cylinder inner wall around and at the same time depending on the circulation angle in the direction of the longitudinal extent of the piston and / or the cylinder inner wall extending trained or arranged in a corresponding receptacle.
  • Isolated in this installation position, they form approximately a contour, which results when a rubber ring at two opposite points detected with two fingers and these are rotated against each other. Proceeding from these points, the contour of a circular section, which merges into a straight line running obliquely to the opposite circular section, results approximately initially.
  • With two arranged between the piston outer wall and cylinder inner wall, axially spaced sealing structures having approximately this roughly described course, in cooperation with two axially formed on the piston and / or in the cylinder openings, for. B. in the form of delivery slots, by means of a rotary stroke movement of the piston in the cylinder a pump with exactly definable delivery volume can be realized.
  • A conveyor slot may have along its course both in the longitudinal direction of the piston and / or the cylinder wall as well as in its or their circumferential direction extending components. A first conveyor slot may, at a conductive connection with the supply volume for the beverage additive, realize an inflow into the space forming the delivery volume. After separation of this fluid-conducting connection, the delivery volume is closed to the outside until a second opening, preferably also a delivery slot, is brought into a conductive connection with a liquid outlet channel leading out of the exchange container. By suitable design measures, the beverage additive contained in the delivery volume can be conveyed into this liquid outlet channel and subsequently, by means of connections to be described in more detail below, in a further movement of the delivery piston into the beverage machine.
  • A possible constructive solution is that the piston is raised during its coverage of its outlet opening from lying between the two above-described sealing elements delivery volume with the liquid beverage additive outlet channel in its vertical position, so that the beverage additive run through the liquid outlet channel into the machine can, preferably gravitational. After appropriate emptying of the stroke volume, this fluid-conducting connection with the liquid outlet channel is interrupted again and after appropriate further movement of the reciprocating both in the direction of rotation and in the stroke direction again overlaps the inlet opening with the reservoir of the beverage additive change container causes to initiate the next dosing.
  • Alternatively to a hub rotary pump z. B. also a peristaltic pump as dosage come into application. Again, a very accurate dosage is feasible. Conceivable, however, are other pump forms for the promotion of liquid beverage additive from the removable container designed as a swap body in the beverage machine.
  • To realize a simple to produce and reliable acting connection between the provided in the swap container beverage additive metering device and arranged in the beverage machine drive unit can be provided in a further advantageous manner, in particular a position-movable coupling element. This positional mobility may relate to a radial and / or axial position. A pivotability with respect to a longitudinal axis of the drive unit and / or a driven therefrom, a torque-emitting drive element and / or a thus generated rotational movement receiving connection element of the metering unit can hereby be realized in an advantageous manner.
  • This can on the one hand user-friendly larger insertion or slip-on when changing the swap body with still guaranteed, according to the operation provided for mounting possible. On the other hand, thereby larger tolerances for both the beverage machine and in particular for the liquid swap body can be allowed or compensated. In particular, in very confined spaces, as is the case because of the increasingly compact design of beverage machines, this can cause a significant increase in ease of use.
  • In a further advantageous manner, the coupling element may be formed as a resilient element and / or be connected by means of such with the drive-side output or the dosing unit side drive. A further increase in user-friendliness can be made possible by the provision of a centering element. This can be designed, for example, in the form of a centering pin, which in turn can have drivers, for example in the form of teeth or other corresponding geometric contours, in order to be able to realize a corresponding torque or rotary motion transmission. Preferably, means are also provided for a height compensation, for example in the form of the previously mentioned, resilient element. Such a height compensation can z. B. the stroke of the reciprocating plus plus possibly an additional, z. B. for safety's sake include spring travel.
  • The torque transmission can be carried out in an advantageous form-locking manner. This allows an accurate detection of the pump state, that is, for example, the hub rotary piston whose exact detection of its angular position and / or its position along the stroke movement to be carried out by him. This can be realized, for example, by the provision of rotor position detection means. According to the recognized position, an exact control of the amount of beverage additive to be delivered is also possible. This may be of particular interest if a successive additive dosage within a delivery stroke is desired. This can be achieved for example by a predosing, which after a certain exposure time by further metering or re-dosing of additives in the beverage machine in the sense of a possible subdivision into a "predosing section" and a so-called " Main dosage section ". Also, mixing with another liquid, especially with water, eg. B. to provide a larger amount of beverage can thereby be realized in an advantageous manner.
  • In this way, flow rate control quantities and / or conveying direction reversing means can be realized. For this purpose, in a particularly preferred embodiment, only the direction of rotation of the drive unit can be reversed to z. B. to be able to suck water from a correspondingly provided connection to the additive outlet channel and to mix in a corresponding manner with the liquid additive therein.
  • With respect to a mixture of a beverage additive with another additive, or even with water, an agitator may also be provided for embodiments of additional swap bodies filled with non-fluid additives, such as powder, granules, tablets or the like, in order to achieve the best possible results Mixing and in particular dissolution of the primary additive in the second additive or in water to be able to guarantee.
  • By providing rotor locking means, it can be ensured that the rotational angle set on the output of the drive unit or on the coupling element can not be changed from the outside under operating conditions. With one of the interface between additive metering device and drive unit, which is realized by the coupling element and the output or drive flange to be connected to it when changing the additive swap body, depending on which side the coupling element is provided, impressed preference orientation can be ensured that only a swap body can be substituted into the beverage machine whose drive flange or a coupling element arranged thereon has exactly the same rotational angle orientation as the output flange or the coupling element arranged thereon.
  • As a result, for example, a novelty check for a newly inserted swap body is possible. For already before, z. B. used in this machine swap body, for example, an adjustment of a rotation angle may be provided, which is clearly different from that for receiving a newly inserted swap body. This can be done, for example, by setting the rotation angle and monitoring of a corresponding control unit provided for this purpose before signaling, if required, of a required change.
  • For example, for this purpose, the motor can be controlled accordingly, wherein advantageously a sensor for rotation angle and / or stroke position detection is provided for the pump piston. For alternative pump designs, alternative sensor designs can be used accordingly. For example, in a peristaltic pump, the rotational position of the conveyor rotor can also be interrogated. Alternatively or additionally, a position detection on the rotor position of the motor can be realized, preferably in combination with a detection of its number of revolutions, so that in consideration of the transmission ratio again an exact position determination of the conveying element, for. B. the reciprocating piston is possible.
  • In one possible embodiment, the sensor may be designed as a Hall sensor. For detecting a rotational angle position z. B. may be arranged on the coupling element or another suitable location, a magnet whose magnetic field detected for determining, for example, a stroke position and / or a rotation angle detected by the Hall sensor to the control unit.
  • By providing a plurality of individual magnets, for example along the circumference of the coupling element and / or along its longitudinal axis, a segmentation of the rotation angle and / or a length division of the stroke can be realized. This allows a more refined control of the flow rate for the additive to be delivered and / or another liquid to be sucked back by the direction of flow reversal.
  • The arrangement of the metering device between the swap body and the beverage machine, a simple coupling of the outlet of the metering unit can be realized with the beverage machines. This can be realized, for example, in the form of a respective coupling unit which is designed to be complementary to the swap body and to the beverage machine. For a connection that is as easy to handle as possible, these two elements can be designed to be substantially rigid and preferably provided with guide contours. By this intermediate arrangement, a direct metering in the machine is possible, which in particular allows an exact control of the supplied or supplied amount of additive.
  • In a further advantageous manner, an otherwise necessary valve, in particular on the additive-swap body, can be dispensed with by this intermediate arrangement.
  • In a further advantageous manner, data communication means can be provided by which, for example, a detection of cartridge-specific data can be made possible. For this data can be read and / or sent. One possible technique for this is the RFID technology dar. But are also other, for. B. based on optical and / or electromagnetic based information systems.
  • In a particularly preferred manner, energy-carrying lines which are required anyway for the data transmission can be used. For example, this can also be coupled to a decentralized, monitoring the motor control unit. This can for example be arranged as a microprocessor on a small board in the vicinity of the motor, which is realized for example as a PWM-controlled motor. Thus, on the one hand, only a few lines are required and, on the other hand, because of the proximity of the control unit, they can transmit to the units (motor, sensor, data communication element, data memory and the like) which are to be controlled and / or supplied with information or output by it. also be kept very short.
  • A control circuit which, for. B. according to predetermined criteria, automatically triggers a dosing can increase the user-friendliness of such a beverage machine even further. In particular, it can be provided here that metering operations are carried out, for example, at specific time intervals and / or depending on a specific number of beverage preparations.
  • A particularly advantageous embodiment of the drive coupling forms the embodiment of a dog clutch.
  • A dog clutch is structurally simple and functionally reliable. The torque transmission via a dog clutch is also excellent, with ease additional damping elements, locking elements or the like can be provided.
  • Furthermore, in the realization of a dog clutch and a simple form of the above-mentioned detection of a new interchangeable container are provided in the exchange of the container, a predetermined angular position of the machine-side coupling element on the one hand and the container-side coupling element on the other hand is provided.
  • In a particular embodiment of the invention, the swap body is designed to be flexible. Such a "baggy" design of the container has the advantage that it can contract during emptying, so that the container can be self-contained and without ventilation.
  • In another embodiment of the invention, a rigid container is provided, which has advantages in handling and is provided for a functional emptying with a vent opening, optionally with a vent valve.
  • Advantageously, a valve is also provided at the outlet of the container that seals the swap body. In a particular embodiment of the invention, this valve is designed so that it is opened when inserted into a beverage machine. For this purpose, for example, a valve body can be pressed in via a machine-side plunger. The valve body can be held by a force element, such as a spring in its closed position with removed container.
  • Furthermore, an overpressure in the swap body can be provided to improve the tightness of the exhaust valve. Such an overpressure can readily be combined with a force element provided, so that a multiple action in the closed position of the valve body is present.
  • In an introductory beverage machine advantageously also an electronic coding, for example via a so-called RFID element can be made to allow identification of the swap body by the beverage machine. Optionally, the operation of the beverage machine can be made dependent on the presence of a correct interchangeable container.
  • In a particular embodiment, the beverage machine is designed as a coffee machine, in particular as a coffee machine such as z. B. are often found in office coffee kitchens.
  • According to a second aspect, the present invention relates to a beverage additive container, which is characterized in that it is intended for use in a beverage machine, as described above.
  • Embodiment:

  • As a preferred embodiment of a beverage machine is in the 1 purely by way of example and without restrictive intention a fully automatic coffee machine shown. This has, according to the embodiment shown, a beverage additive swap body 3 for one or more additives 3.1 , z. B. and in addition an additive metering device 4 on.
  • The additive metering device 4 is provided so that first parts 4.10 with the additive swap body 3 are formed exchangeable. These include z. B. a metering pump 4.11 , This can be formed in a preferred embodiment as a reciprocating pump or otherwise, for example in the form of a peristaltic pump.
  • Another part 4.20 the additive metering device 4 is in the beverage machine, here in the coffee machine, arranged so that when inserting the container as swap 3 in a corresponding receiving shaft of the additive outlet 3.2 and a drive input 4.12 with the correspondingly complementary, on the coffee machine 1 trained connections 4.1 and 4.21 be joined together effectively and so form a line coupling for the direction of the additive.
  • For connection of the pump-side drive input 4.12 is a mechanical drive coupling 4.21 provided at an output of a drive unit 4.22 is arranged. It serves as a coupling point between the two parts 4.10 and 4.20 the additive metering device 4 ,
  • By means of the components 4.1 to 4.4 can the additive from the pump connection 3.2 to the point of addition 4.4 for cleaning a brewing unit 5 with the appropriate delivery rate. These are, starting from the additive outlet 3.2 a device-side additive connection 4.1 , an additive feed line 4.2 , an additive feed 4.3 and by way of example an additive delivery element 4.4 shown.
  • At the tank side connection 3.2 and / or on the device-side connection 4.1 can be provided in a further advantageous manner, a valve. Purely by way of example is the position for this 3.2.1 shown. In particular, this can advantageously be opened in each case upon contact with the complementary connection element in order to prevent leakage of the additive from the tank on the one hand and possible contamination and / or air entrapment in the pump supply line on the other hand. In principle, this could also be dispensable, since the pump is directly in front of the outlet 3.2 in the container 3 is arranged and can seal it.
  • To a pressure equalization in the container, here in the form of an exemplary cartridge 3 To allow for the proper removal of the additive, this is with a vent 3.3 Mistake. This can advantageously also have a valve, for example, to prevent leakage of the liquid additive.
  • To avoid confusion, the tank or the replacement cartridge may have a contour that is usually also used by such automatic coffee machines, for example a parallelepiped. This eliminates confusion between a water treatment filter cartridge and such an additional replacement cartridge in one and the same machine.
  • In order to enable an automatic procedure of a dosing process, a control unit 6 be provided. Advantageously, for this purpose, the control unit can be used, which is provided for the basic operation of the coffee machine. It is also conceivable, however, a separate.
  • The level of the container 3 for the additive can by means of a level sensor 7 be recorded. This can be for example in the form of a Be formed infrared sensor. The corresponding infrared light source 7.1 is here for example arranged on the opposite side of the formed as a removable cartridge tank. The positioning of these sensor elements can, for. B. in guides and / or mounts for the cartridge 3 be provided. To fix the cartridge sliding, plug-in, folding, snap-in connections or the like may be provided to protect the container integrated into the machine housing.
  • By means of a level indicator 8th the level of the additive can be displayed, for example, in appropriate ratio display and / or by a signal element that emits a corresponding signal with sufficient filling and emits an appropriate warning signal in the event of imminent and / or already occurred emptying, z. B. acoustically and / or optically.
  • The elements of the brewing unit are, again by way of example, a brewing chamber 5.1 , which is formed here, for example, pivotally, a service water connection 5.2 and a housing accommodating these 5.3 and an inlet formed therein 5.4 through which the coffee powder discharged from the coffee grinder can be picked up. About the brew unit outlet pipe 5.5 the brewed coffee becomes a coffee line 10 and the coffee outlet 10.1 fed. The promotion of coffee can z. B. by means of a movable piston 5.6 respectively. For the retention of the pomace can a sieve 7.7 be provided.
  • Further examples here in the housing 13 the coffee machine still arranged components are a pomace peel 11 and a drip tray 12 ,
  • The 2 shows the two parts 4.10 and 4.20 the additive metering device 4 in an exempted representation. The dash-dotted line 11 represents the dividing line or the interface between these two main components and thus also between container and device.
  • A heart of the with the additive swap body 3 exchangeable parts 4.10 the additive metering device 4 represents the additive-conveying agent, here for example in the form of a reciprocating pump 4.11 This comprises a housing 4.11.1 , an additive feed 4.11.2 and an additive effluent 4.11.3 , Inside the rotary reciprocating pump is a both rotationally and axially movable trained metering in the form of a rotary reciprocating 4.11.4 arranged (not visible here and therefore indicated by dashed arrow).
  • The device-side parts 4.20 the additive metering device 4 comprise a drive unit 4.22 for providing a drive movement driving the metering pump. This is done via a rotary motion, which is the rotary piston 4.11.4 by means of a motor 4.22.1 with the interposition of translation means, here in the form of a gear transmission 4.22.2 with gears 4.22.3 , and a clutch 4.22.4 drives.
  • On a circuit board 4.23 is a control unit 6 arranged, z. B. in the form of a microprocessor, here for example in the drive unit 4.22 integrated. You can use the additive dosing device 4 monitor accordingly. That means she controls or regulates the engine 4.22.1 under feedback of a rotational and / or lifting position of the rotary reciprocating piston. For this purpose, it receives the corresponding information about a Hall sensor 4.24 , the corresponding position information from one to the clutch 4.22.4 arranged magnets 4.25 originating magnetic field.
  • In the embodiment shown here, the magnet is realized as the clutch comprising a magnetic ring, by means of which the Hall sensor can detect axial positions of the rotary piston driven therewith. Under the knowledge of the contour of a movement of the rotary reciprocating piston guiding guide in the interior of the pump can hereby simultaneously also a corresponding angular position of the rotary reciprocating piston are determined, and thus also a statement about the thereby to be conveyed delivery of additive. Optionally, this can also be used for a number of revolutions of the engine rotor, which, taking into account the transmission ratio of the gears can also allow a rotation angle determination of the rotary reciprocating piston.
  • To the electrical supply for energy and data are lines 4.26 shown.
  • The additive to be metered by the pump into the device is at the interface between the additive swap body and beverage machine from the additive effluent 4.11.3 in the device-side additive connection 4.1 and further into the additive supply line 4.2 promoted to finally on the additive feed 4.3 as shown in the 1 to be introduced into the beverage preparation unit to be cleaned.
  • In the 3 are in explosive exploded view along the longitudinal axis of the pump 4.11 Elements of the pump and the coupling 4.22.4 shown in more detail. In the lower part of the case 4.11.1 is a window-shaped recess as a fixing agent 4.11.5 shown for engagement in a complementary element. At the Additive flow 4.11.3 is an example of a seal 4.11.6 located. Axial under the housing is the pump piston 4.11.7 the rotary reciprocating pump 4.11 shown. When assembled, it is over the drive axle 4.11.8 stuck, on which a backdrop 4.11.9 is provided for controlling the rotation angle dependent lifting movement of the rotary reciprocating piston. It can, for example, travel along a complementary cam formed in the interior of the pump housing and under the action of a spring force in the longitudinal direction of the drive axle 4.11.8 seen over a revolution revolution perform an oscillating stroke movement.
  • The spring force comes in this embodiment of the spring element exemplified here as a spiral spring 4.22.5 the clutch 4.22.4 , This spring serves as an elastic, torque transmitting connection between the with the transmission 4.22.2 connected output 4.22.6 and the clutch 4.22.4 , In this way, the coupling can be realized both with respect to the axis pivotable and radially and axially positionally variable and thus compensate for both manufacturing tolerances and allow for insertion of an exchanged additive container easier coupling with the housing-side connection components.
  • A further relief for this purpose is a centering pin formed on the front side of the coupling 4.22.7 and rounded contours of driving teeth 4.22.8 represents.
  • The magnetic ring 4.25 is by means of a spring-elastic holding element 4.27 held positionally fixed to the coupling.
  • The 4 shows a plan view of the drive unit 4.22 with the housing open. Here are the essential components, the engine 4.22.1 , The gear 4.22.2 and provided for transmitting the rotational movement of the aufzusteckende rotary reciprocating pump clutch 4.22.4 shown.
  • The 5 shows a device-side provided, so-called "receiving shaft" 4.30 for an additive swap body to be used therein as a swap body 3 as shown in the 6 , Inside the receiving shaft are the clutch 4.22.4 and at its front side ausgebilete centering pin 4.22.7 as well as the surrounding driving teeth 4.22.8 to be recognized as a torque transmitting unit for the thus to be driven rotary reciprocating pump. This in turn is as with the additive swap body interchangeable part 4.11 housed in the container housing.
  • In the inserted state of the removable container 3 engage both the mechanical components provided for driving the rotary reciprocating pump components and the additive-conducting compounds 4.1 and 4.11.3 each other. To z. B. at removed exchange container 3 To reliably prevent a permanent rotation of the angular position of the drive teeth can also be provided in the following rotor locking means. These can, for example, by a corresponding control of the engine 4.22.1 be achieved to the effect that it does not move and therefore no angular position change of its output is possible via the gear connected to it. Another possibility is that via the spring element 4.22.5 Such a Drehmomententkupplung is effected, that in case of rotation of the coupling orientation after their release, this assumes its original position again.
