    Technical area
    The present invention relates to a coffee machine with a device for portioning coffee beans according to the preamble of the first claim.
    State of the art
    Some coffee machines of known manufacturers of coffee machines include means for portioning coffee beans.
    For example, EP 2 578 120 A1 discloses a coffee machine with a device for portioning coffee beans, wherein the device for portioning coffee beans essentially comprises a metering chamber with adjustable metering chamber volume. By means of two opposing chamber walls, which simultaneously act as a slide for passing coffee beans, the Dosierkammervolumen is adjustable relative to each other by a translational movement of the two opposite chamber walls. In this case, a chamber wall is designed to be movable in order to complete the translatory movement or to adjust the distance between the chamber walls. By means of an electric motor on the one hand, the translational movement of the movable chamber wall and on the other hand, the slide movement for passing coffee beans feasible. This known from EP 2 578 120 A1 device for portioning coffee beans of a coffee machine is cumbersome and complicated from a technical point of view.
    In addition, a device for portioning coffee beans is known, for example, from document US 2012/0 070 546 A1. The device for portioning coffee beans comprises a metering chamber with adjustable Dosierkammervolumen, wherein the Dosierkammervolumen is adjustable relative to each other by a translational movement of two opposing chamber walls. The adjustment of the distance between the chamber walls must be accomplished in a complicated and cumbersome way by means of an associated with the opposite chamber walls additional spacer, for example in the form of a set screw.
    In addition, from document DE 20 2011 005 003 U1 a coffee machine with a two-chamber bean container and a device for portioning of coffee beans is known. The device for portioning coffee beans is essentially formed by transport screws between in each case a bean container and the grinder, wherein a screw conveyor is rotationally driven. The design of this known fully automatic coffee machine is particularly space-consuming and corresponds to a particularly complicated design, since the aligned perpendicular to the direction of fall of the coffee beans transport screws each have a laterally arranged drive.
    Presentation of the invention
    The present invention has for its object to provide a coffee machine with a device for portioning coffee beans, which overcomes the disadvantages of the prior art and in particular has a space-saving and simple design.
    This object is achieved by a coffee machine with the features of claim 1.
    According to the invention, the coffee machine comprises a rotatably mounted shaft which is directly and indirectly connected to a drive in an operative connection, wherein the shaft rotatably connected to a rotatable grinding element of the grinder and indirectly or directly with a rotationally driven device for portioning coffee beans in Active connection is, so that the rotatable grinding element of the grinder for grinding coffee beans and the device is rotatably driven together by means of the shaft. Such a rotary drive of the device for portioning coffee beans has the fundamental advantage that rotational movements in comparison with translational movements are quiet and a low-wear operation is possible. Furthermore, the operating speed can be regulated particularly easily with a rotary drive.
    Preferably in combination with the rotatably driven shaft, the device for portioning or portioning of coffee beans comprises a to the at least one coffee beans supply hopper arranged portioning and arranged between Portionierscheibe and grinder bottom plate. In this case, the portioning disc comprises at least one coffee portion bore for receiving at least one coffee bean from the at least one coffee bean supply container. Furthermore, the bottom plate comprises at least one discharge opening for emptying the coffee port hole. In this case, the shaft is rotatably connected to a rotatable grinding element of the grinder and the Portionierscheibe or the bottom plate so that the rotatable grinding element of the grinder for grinding coffee beans and the Portionierscheibe or bottom plate for operating the device by means of the shaft is driven together. For the purposes of the present invention, the at least one discharge opening of the bottom disk is arranged such that the at least one discharge opening can at least partially be brought into coincidence with the at least one coffee portion bore. The portioning disc advantageously comprises a plurality of coffee port bores, preferably uniformly distributed over the circumference, for accelerating the portioning process. Compared to a portioning by means of the rotationally driven portioning known from DE 20 2011 005 003 U1, a device designed in this way for portioning coffee beans produces a particularly targeted, precise and nevertheless rapid portioning. For example, if a coffee port bore is sized or dimensioned to correspond to one fifth of a portion of a desired coffee, then a portion for the desired coffee can be obtained very quickly and precisely by draining five portions of coffee port.
    Preferably, on the one hand, the shaft rotatably connected to the Portionierscheibe, whereby in other words the shaft is as it rotatable with the Portionierscheibe, while on the other hand, the bottom plate is substantially fixed or fixed in other words fixed and not rotatable with the shaft. As a fixed bottom plate can also be understood a portion of the facing Portionierscheibe with at least one discharge opening.
    Alternatively, it is conceivable that on the one hand, the shaft is rotatably connected to the bottom disk, which in other words, the shaft is rotatable together with the bottom disk, while on the other hand, the Portionierscheibe is substantially fixed or fixed in other words firmly and not with the Shaft is rotatable.
    In terms of a preferred embodiment of the present invention, the grinder is designed as a conical grinder. Usually, preferably, designed as a conical grinder, grinder is preferably constructed of a rotating during a grinding first grinding element and a second, fixed to the grinder, grinding element. Particularly preferably, the first grinding element is a grinding cone and the second grinding element is a grinding ring.
    In terms of a further preferred embodiment of the present invention, the shaft can be directly connected to a rotatably mounted portioning unit of the device for portioning coffee beans in operative connection, i. the shaft forms the central axis of rotation or rotation axis of the internal grinding cone and the portioning disk. In other words, it is advantageously achieved by the arrangement of the shaft in the coffee machine according to the invention that the axis of rotation of the internal grinding cone essentially corresponds to the axis of rotation of the portioning disk or the bottom disk. Thus, it is achieved by the coincidence of these two axes of rotation by the arrangement of the shaft in the coffee machine, that the grinding cone and the Portionierscheibe or bottom plate is driven by the shaft together in one and the same rotational movement.
    Alternatively, it may be desirable for reasons of space that the coffee bean supply container of the coffee machine is arranged offset laterally relative to the grinder.
    In the context of a preferred embodiment of the present invention, in this context, the shaft with the portioning disk of the device for portioning coffee beans, which is formed as a drive element rotatably mounted about an additional axis, is indirectly, i.e. For example, by means of a V-belt, in operative connection, whereby the rotatable grinding element of the grinder and the rotatably mounted portioning unit for operating the portioning device are rotatably driven jointly by means of the shaft. Particularly preferably, a translation can be formed between the shaft and the additional axis, so that the device for portioning coffee beans and the grinder can take place at a respectively preferred rotational speed.
    In terms of a preferred embodiment of the present invention is understood by a rotationally fixed connection of the shaft with the grinding cone, that the shaft is integrally formed at one end to the grinding cone and thereby fixed in rotation.
    If in the case of an immediate operative connection of the shaft with the Portioniereinheit, wherein the axis of rotation of the shaft of the rotation axis of the Portionierscheibe, the shaft is formed on the Portionierscheibe the device for portioning coffee beans or rotatably fixed, then form the means for portioning of coffee beans, the shaft and the grinding cone formed on the shaft a unit or a single component.
    Preferably, the unit thus formed on the means for portioning coffee beans, in particular on the Portionierscheibe, stored in the inventive coffee machine so by means of at least one suitable bearing, so that advantageously can be dispensed with a further storage below the portioning device. In particular, it is therefore advantageously possible to dispense with additional storage in the area of the grinder, as a result of which, as a further resulting advantage, the risk of a possible settling of ground coffee beans in the area of the grinder is reduced. In other words, storage at the portioning device, i. viewed in the direction of gravity top area, a suspended storage of the unit of portioning, shaft and grinder achieved. A suitable bearing in this case must act as a suspension on the one hand and on the other hand ensure the rotatability of the Portionierscheibe.
    Particularly preferably, the device for portioning coffee beans of the unit thus formed is mounted on a dedicated support housing of the inventive coffee machine based on a suitable bearing.
    Furthermore, in the sense of a preferred embodiment of the present invention, the drive is formed by the grinder motor.
    Such an arrangement of a shaft allows the common driving of the grinding cone and the portioning or the bottom plate advantageous that only a drive for the coffee bean portioning and the grinder is necessary. In other words, space saving achieves a drive in one and the same rotational movement a portioning of the coffee beans and grinding the coffee beans in the grinder. On a space-consuming, translational movement in the context of portioning can thus be advantageously dispensed with in contrast to the prior art. Furthermore, such an arrangement of a shaft has the advantage that a significantly reduced height can be achieved.
    Preferably, the Portionierscheibe is provided with at least one Kaffeeportionenbohrung, wherein in each case a preferably trough-shaped ausgestaltet Kaffeeportionenbohrung example, with at least about 8 coffee beans can be filled. In the context of a preferred development of the present invention, a respective coffee port hole has an arbitrarily designed, suitable geometry, i. in particular, a suitable diameter of the coffee port bore in combination with a suitable thickness of the portioning disk to accommodate at least about eight coffee beans. Conceivable is a cake-shaped portion of the coffee port, wherein such a shape corresponds to a particularly advantageous subdivision in a preferably circular-shaped portioning disk with a desired, high number of coffee port bores. Alternatively, any other form of Kaffeeportionenbohrung conceivable, for example, circular, oval etc. cake-shaped coffee port holes is preferably also a discharge opening cake piece-shaped, with any other form of drain opening is conceivable, for example, circular, oval, etc. Very particular preference the Kaffeeportionenbohrung and the discharge opening on a congruent or congruent shape, whereby each advantageous complete emptying is ensured. Furthermore, ideally, the discharge opening with respect to the coffee port bore may have an enlarged dimension, for example in the form of a slot, which counteracts jamming of coffee beans when emptying the coffee port hole.
    Preferably, such an arrangement of a shaft is used in connection with a relative to the grinder within the coffee machine laterally offset, directly or indirectly operatively connected to the shaft drive or grinder motor, as known from the Swiss patent application no. 01 757/14 is. By the term "lateral" displacement of the grinder motor is meant a lateral displacement relative to the grinder, whereby the grinder motor is ideally located in a region outside of a substantially extending in the direction of gravity line between grinder and brewing chamber. The lateral displacement of the drive or grinder motor advantageously makes it possible for ground coffee beans to be supplied to the brewing chamber as a whole by means of gravity without intermediate storage and dispensing with a grinding stock chamber. For example, such a lateral displacement of the grinder motor can be achieved by the grinder motor is in operative connection with an external toothing of the portioning of the device for portioning coffee beans.
    In principle, however, it also corresponds alternatively to a possible development of the invention that the shaft is operatively connected to a drive, wherein the drive is arranged below a Mahlgutkammer a grinder, on a side facing away from the coffee bean feed.
    Further advantageous embodiments are specified in the further dependent claims.
    Preferably, the coffee machine according to the invention comprises at least one slide, wherein the at least one slide between the at least one coffee bean supply container and the Portionierscheibe is arranged. Particularly preferably, the coffee machine according to the invention comprises two or more sliders with the advantage that it is possible to choose between different types of coffee or that by operating, for example, two sliders, a mixture of one's own taste can be obtained from two different coffee beans.
    As part of a fixed bottom plate or housing portion with drain holes and rotatable by the shaft Portionierscheibe may alternatively at least one slide at least one first perforated disk, each with a hole per coffee bean hopper between the at least one coffee bean hopper and the means for portioning of Be arranged coffee beans, wherein in the presence of two coffee bean supply container, a second perforated disc with only one hole in addition ideally adjacent to the second perforated disc is arranged. For the purposes of the present invention, the at least one hole of the at least one perforated disk is arranged such that the at least one hole can at least partially be brought into coincidence with the at least one coffee port hole. The at least one perforated disc can, for example, be set in rotation by means of a stepping motor or an electromagnet and can be brought into a desired position.
    According to a further preferred embodiment of the present invention, the inventive coffee machine can be configured such, for example, with a suitably designed control unit that the at least one slide can be opened together with a full open position only in an arbitrarily selected, pre-definable intermediate position. In this context, for example, an intermediate position of the slider may be adjustable, in which the slider is opened only halfway relative to the coffee port hole. By such adjustability of intermediate positions of the slide can advantageously only a partial filling of the coffee port hole with a respective coffee bean variety from a respective coffee bean supply container can be achieved, whereby the possibilities for obtaining mixtures of different coffee beans can be further expanded. Alternatively, it is conceivable that, for example, the control unit is designed such that by means of a timer for a predeterminable time a respective slide open or the holes of the perforated discs are brought into line and thereby mixtures of different coffee beans are achieved.
    A problem which may occur during operation of the coffee machine according to the invention, concerns a possible pinching individual coffee beans between Portionierscheibe and first and / or second slide or perforated disc or between Portionierscheibe and bottom disc and a concomitant blocking. For example, such pinching of individual coffee beans may take place in a closing area between the coffee port hole of the portioning disk and the bottom disk discharge opening when, on rotation of the portioning disk, its coffee port hole is opposite the discharge opening of the bottom disk from a registered condition, i. when emptying the coffee port hole, is moved. On the other hand, when the first or second slider is closed relative to the coffee portion bore of the portioning disk, individual coffee beans can be clamped in a closing area.
    Preferably, the Portionierscheibe and / or the bottom plate and / or the first and / or second slide at least partially such elasticity or elastic means such as protruding rubber lips to allow a displacement of volume by jammed coffee beans and thereby a possible blocking in the closing area to prevent. For example, the rubber lips may be arranged and configured to flatten in the region of a jammed coffee bean. Alternatively, the Portionierscheibe and / or the bottom plate and / or the first and / or second slide or perforated disc have such stability and strength that a pinched coffee bean is sheared, for example by the Portionierscheibe and / or the bottom plate and / or the first and / or second slide or perforated disc are made at least in a closed area of hardened steel or the like. As an alternative or in addition to a particular stability and strength, the portioning disk and / or bottom disk and / or the first and / or second slider may be arranged, at least in sections, in a closing region with an oblique, ie. be provided to a closing tapered, and / or sharp edge so that a coffee bean in the closed area either pushes down or divided situationally in a shearing motion and thereby against a straight, non-tapered closing force reduced force. Furthermore, it is conceivable that a rubber lip or spring flap or the like is arranged between the coffee bean supply container and the first or second perforated disc in a recess. In addition, it is conceivable that a wiper is mounted between the coffee bean supply container and the first or second perforated disc for conveying coffee beans into a coffee portion bore of the portioning disc.
    Preferably, the at least one discharge opening of the bottom disk is arranged in an area outside the at least one slide. Such an arrangement of the discharge opening advantageously prevents uncontrolled falling through of coffee beans from the at least one coffee bean supply container into the grinding device, when the coffee portion bore and the discharge opening are substantially in register for emptying the coffee portion bore, since in the area outside the at least one slide no Passage for the exit of coffee beans from the at least one coffee bean hopper is present.
    Preferably, the coffee machine according to the invention comprises a mounting unit for mounting the at least one coffee bean supply container. For example, the mounting unit may have a latching mechanism, by means of which in each case the at least one coffee bean supply container is detachably connectable. Particularly preferably, the coffee machine according to the invention comprises a sliding bush, which is suitable for receiving the shaft, wherein the sliding bush is preferably arranged on the mounting unit and wherein the shaft is guided in the sliding bush and rotatably mounted. Such a recording of the sliding bush in the shaft advantageously improves the running accuracy and a stable arrangement of the shaft, wherein the mounting unit can advantageously ensure a stable attachment of the slide bushing.
    Preferably, the coffee machine according to the invention comprises a funnel-shaped device for receiving portioned coffee beans, wherein the funnel-shaped device between the device for portioning coffee beans and the grinder is arranged. Such arranged, funnel-shaped device has the advantage that the portioned coffee beans lossless and centered the grinder can be fed.
    Particularly preferably, the funnel-shaped device comprises at least opening and closing mechanism such as a third slider, said slider is disposed on the side facing away from the device of the funnel-shaped device. This third slide can advantageously fulfill in a closed state the purpose that the portioned coffee beans are collected before grinding in the grinder. Since usually in the inventive coffee machine, the shaft passes through the opening of the funnel-shaped device, preferably such a third slide must have a suitable shape to ensure a closed state around the shaft.
    According to a preferred embodiment of the present invention, the funnel-shaped device may be provided with a subdivision into individual sectors, whereby the individual sectors are suitable for receiving and / or storing pre-portioned coffee beans from the device for portioning coffee beans. In each case a sector of the funnel-shaped device may preferably be provided with a respective slider or similar opening and closing mechanism. Such a sector-like subdivision of the funnel-shaped device advantageously allows at the same time a portioning into a respective sector to take place parallel to a grinding of an earlier portion.
    Preferably, the inventive coffee machine comprises a preferably coupled to the grinder motor sensor for detecting the number of revolutions of the shaft or rotatably coupled to the shaft Portionierscheibe. As an alternative to a sensor coupled to the grinder motor, a detection of the number of revolutions of the shaft can be detected and / or controlled electronically or by means of an amperage measurement on the basis of the grinder motor. For example, the grinding time or number of revolutions of the portioning disk can be adjustable by stopping the grinder or the portioning disk when an idle-running number is reached. In terms of a preferred development, the coffee machine according to the invention comprises an evaluation unit and a controller, wherein by means of the evaluation unit, for example based on the revolutions, the number of emptying a filled Kaffeeportionenbohrung evaluable and by means of the controller a desired predeterminable number emptying is adjustable. With particular preference, the first or second slide can also be actuated by means of the control.
    It is a known problem that can be located under coffee beans small stones. Until now, such stones have blocked the grinders known coffee machines or even broken. Known automatic coffee machines are already equipped in this context with an ampere-monitoring of the grinder motor, which registers the exceeding of a predefined resistance in the grinder, the grinder motor is switched off early. Certain known coffee machines generate an alarm and must be opened, for example, in a shop, which is complicated and expensive. Preferably, in this context, the coffee machine according to the invention is configured such that the rotatably mounted shaft of the coffee machine according to the invention is rotatable and height-adjustable, both clockwise and counterclockwise, i. is movable in the longitudinal direction of the shaft. The grinding cone of the grinder in the coffee machine according to the invention has a thread known per se in grinding cones, through which material to be ground can be fed to the grinding gap of the grinder in a rotary motion. Such a rotatable mounting and height adjustment of the shaft is advantageous since, in a preferably opposite at the same time the usual operation, i. the grinding material leading away from the grinding gap, rotational movement by the height adjustment of the shaft or the grinding cone an open position, i. a sufficiently large gap between Mahlkegel and Mahlring can be generated to remove pebbles and any existing unground millbase on the gap and then on the brewing unit in the coffee residue. Due to such a height adjustability of the shaft, the grinding gap or the grinding fineness is advantageously adjustable, so that the preferred grinding fineness can be set to a respective desired or programmed type of coffee bean.
    In addition or as an alternative to such a height-adjustable grinding cone, the grinding ring can also be configured to be height-adjustable so that the open position, i. a sufficiently large gap between Mahlkegel and Mahlring, can be generated to remove pebbles and any existing unground millbase on the gap and then on the brewing unit in the coffee residue. In addition, the preferred grinding fineness can be set by means of such a height-adjustable grinding ring to a respective desired type of coffee bean. The height adjustability of the grinding ring is preferably achieved by means of a threaded ring operatively connected to the grinding ring and a drive.
    In connection with such a height adjustment of the grinding cone and / or grinding ring, the coffee machine according to the invention can be equipped with such an automatic that the grinder moves into the open position after each grinding process and at each choice for a coffee on the preferred grinding fineness.
    A further aspect of the present invention relates to a method for operating the coffee machine according to the invention with a device for portioning coffee beans, comprising the method steps:<tb> a) <SEP> opening the first and / or second slide for filling the at least one coffee port bores of the portioning disk;<b> <SEP> turning the coffee portion bore of the portioning disk over the discharge openings of the bottom disk for emptying the at least one coffee portion bore of the portioning disk, so that the coffee beans are fed directly or indirectly to the grinder;<tb> c) <SEP> Closing the first and / or second slide to complete the portioning process (and further grinding of the coffee beans) after reaching a predetermined number of fillings according to step a) and emptying according to step b) of the coffee port holes.
    In other words, the portioning disk is emptied in the automatic coffee machine according to the invention by the coffee portion bore of the portioning disk being brought into coincidence with the discharge opening of the bottom disk.
    As an alternative to the use of first and / or second slide, at least one perforated disk can be used, each with one hole per coffee bean supply container. In the presence of a single coffee bean supply container of the coffee machine is alternatively brought in step a) a single perforated disc with a single hole by rotation in a filling region below the coffee bean supply container for filling the at least one coffee port bore of the Portionierscheibe. Furthermore, alternatively, in step c) the only hole of the single perforated disc for closing the single coffee bean supply container is brought into an area outside the filling area.
    In the presence of two coffee bean supply container of a coffee machine alternatively to step a) in two perforated disks a first perforated disk with one hole per coffee bean hopper with the hole of a second adjacent perforated disc, and the at least one coffee port hole in a filling below the coffee beans Supply container brought to cover for filling the at least one coffee port hole. Furthermore, alternatively, in step c) by rotation of at least one of the two perforated disks is moved such that its hole is no longer in coincidence with the hole of the further perforated disk for closing a respective coffee bean supply container.
    The portioning on the basis of the device for portioning of coffee beans of the inventive coffee machine by means of setting a predetermined number of revolutions of the portioning or the bottom plate. In other words, the portioning is realized on the basis of the number of fillings achieved and emptying the coffee port holes. When a coffee port hole designed for about 25 coffee beans (equivalent to about 3 grams of coffee beans) is usually achieved after 3 to 4 emptying the coffee port hole of the Portionierscheibe a desired amount of coffee beans to each provide a coffee. Thus, the operation by means of the device for portioning coffee beans advantageously allows a particularly targeted portioning of coffee beans or direct supply of a selected portion of coffee beans to the grinder, wherein a whereabouts of individual coffee beans between the at least one coffee bean supply container and the grinder is prevented.
    The method for operating the coffee machine according to the invention is in the direct supply of coffee beans in the milling device, i. without intervening interception, for example, in a funnel-shaped device, particularly advantageous because at the same time a portioning and grinding of the coffee beans takes place by the direct falling of the coffee beans in the grinder, whereby the risk of a possible whereabouts of coffee beans between coffee bean hopper and grinder is reduced. In other words, it is in principle possible that the rotational speeds for the grinding process and the portioning by means of the device for portioning coffee beans correspond. According to a preferred development of the present invention, alternatively, the device for portioning can be set or adjusted to such a desired rotational speed, so that the fillings or emptying can be controlled to the desired extent. Usually, the desired rotational speed of the portioning device is reduced relative to the rotational speed of the grinding cone of the grinder. Upon completion of the Portioniervorgangs by closing the at least one slide usually the grinding cone of the grinder continues to rotate until reaching the required degree of grinding the ground coffee beans for preparing a coffee, preferably at a desired rotational speed of the grinding cone of the grinder.

By operating a first slider 23 on the first coffee bean hopper 21, first coffee beans KB1 of the coffee bean portioning device 2 can be fed (see also Figs. 2a and 2b), while second coffee beans KB2 of the device are operated by operating a second slider 24 on the second coffee bean hopper 22 2 can be fed. By such an embodiment of the inventive coffee machine 1 can be advantageously achieved that between different types of coffee beans, for example, for an espresso or a café cream, can be selected and by pressing both slide 23; 24 a mixture can be obtained from different coffee beans according to their own taste.
    As shown in Fig. 1, the device 2 comprises one to the at least one of the coffee bean supply containers 21; 22 arranged portioning disk 25 and arranged between Portionierscheibe 25 and grinder 10 bottom plate 26. The Portionierscheibe 25 includes two coffee port holes 28; 28 for receiving coffee beans KB1; KB2 (see Fig. 2b) from the coffee bean supply tanks 21; 22. The functionality of the device 2 for portioning coffee beans KB1; KB2 is further explained in FIGS. 2a to 2c.
    Furthermore, according to FIG. 1, the fully automatic coffee machine comprises a shaft 3, which indirectly, i. is operatively connected by means of a power transmission connection, with a grinder motor acting as a drive 14 and is rotatably mounted about an axis of rotation RP. The shaft 3 is rotatably connected to a rotatable grinding element (see Fig. 4) of a grinder 11 of the grinder 10 (see Fig. 4). Furthermore, the shaft 3 is rotatably connected to the Portionierscheibe 25 such that the rotatable grinding element (see FIG. 4) of the grinder 10 for grinding coffee beans KB1; KB2und the Portionierscheibe 25 for operating the device 2 by means of the shaft 3, for example in the direction of rotation L (or the opposite direction), is jointly driven. 1 shows an example of a sensor 19 coupled to the grinder motor 14 for detecting, for example, a number of revolutions of the shaft. 3
    According to FIG. 1, the grinder motor 14, which is in operative connection with the shaft 3, is arranged laterally relative to the grinder 10 within the coffee machine 1, so that an ideally direct fall line (F) between grinder (11) and a brewing chamber (32). of the coffee machine (1) results, as is known from the Swiss patent application no. 01 757/14. Such a design with laterally arranged grinder motor 14 combines in a simple manner the advantage of ground coffee beans KGohne intermediate storage and possible clogging due to left ground coffee beans and thus complete supply of ground coffee beans in the brewing chamber with a direct supply of a selected portion of coffee beans from the device 2 for portioning coffee beans. Furthermore, this lateral arrangement also supports a compact design. In particular, can be advantageously reduced by dispensing with a below the grinder 10 on the side facing away from the device 2 grinder motor 14 for driving the grinder 11, the height h advantageously.

The translational displacement can be achieved for example by a suitable sliding mechanism, electromagnet or the like. Between the second drive wheel 46 and the threaded ring 41 - as shown in Fig. 8 - a drive pinion 48 may be arranged. On the basis of a suitable embodiment of this drive variant of the fifth embodiment, it is ensured that in any translatory position of the shaft 47, the drive 14 can be in operative connection with at least one of the drive wheels 45 or 46. Furthermore, the drive variant of the fifth embodiment is preferably configured by means of a suitable mechanism such that depending on the operating state either the drive wheel 45 can be decoupled from the drive pinion 44 or the drive wheel 46 can be decoupled from the drive pinion 48. This drive variant of the fifth embodiment advantageously makes it possible for only one drive 14 to be required, depending on the operating state, both for setting the gap S between the grinding ring 16 and grinding cone 15 and for driving the portioning disk 25 or the grinding cone 15.
    Optionally, the coffee machine according to the invention can advantageously be configured on the basis of suitable electronics such that, depending on the operating state, the portioning disk 25 of the portioning device 2, the grinding cone 15 or the setting of the gap S can be set to the respectively preferred rotational speed.
