Description

Title of the invention: Device for dispensing liquids contained in a set of bottles. Technical field

[0001] The present invention relates to the field of liquid dispensing devices. Such devices make it possible to prepare a mixture of different liquid compounds contained in different storage bottles, according to well-defined proportions of the different compounds. Previous technique

[0002] Devices for preparing mixtures of different liquid products for private use have already been proposed. Such devices allow users to prepare their own cosmetic products from various basic components contained in different bottles. These components are mixed in specific quantities to obtain a desired composition, generally based on a recipe.

[0003] Known devices are generally complex to use, or impractical, or even inaccurate.

[0004] Thus, overdoses of certain products are possible, particularly when some components are added in small quantities. In the case of preparing a mixture containing essential oils, potential overdoses can be dangerous for users and should be avoided.

[0005] In addition, the use of several basic products may require cleaning of the device before dispensing a new product, this cleaning being intended to eliminate the quantity of old product still present in the device, before dispensing the new product.

[0006] There is therefore a need to provide a device for preparing a mixture of liquid products contained in different containers or bottles, with improved operation. Summary

[0007] To this end, a device for distributing liquids contained in a set of bottles is proposed, the distribution device comprising: - a frame, - a set of supports movable relative to the frame, each movable support comprising a fastening device configured to receive a bottle containing a liquid, in which each movable support can be moved between: a first position, called the resting position, in which the liquid remains contained within the bottle, and a second position, called the flow position, in which the liquid flows from the bottle in such a way as to distribute the liquid towards a collection container, - a set of actuation devices, each actuation device being configured to selectively move a movable support between the first position and the second position, - a control device for the set of actuation devices configured to start and stop a flow of liquid from each bottle.

[0008] Each support of the dispensing device can receive a bottle containing a liquid product to be incorporated into a mixture to be prepared. Each liquid to be dispensed to carry out the desired preparation is poured directly from the bottle containing that product. A control device allows the flow of liquid to be started and stopped in order to obtain a desired quantity of liquid.

[0009] The features listed in the following paragraphs can be implemented independently of each other or in any technically possible combination:

[0010] In the second position, called the flow position, the liquid contained in a bottle flows by gravity.

[0011] According to one embodiment, the dispensing device includes a device for measuring a quantity of liquid dispensed by each bottle, and the dispensing device is configured so that a quantity of liquid dispensed by each bottle is equal to a predetermined quantity.

[0012] The control device is configured to control each actuating device in the set of actuating devices so as to trigger the flow of the liquid contained in the bottle. To do this, the actuating device moves the movable support from the first position to the second position.

[0013] The control device is also configured to control each actuating device of the assembly of actuating devices so as to interrupt the flow of the liquid contained in the bottle. To do this, the actuating device moves the movable support from the second position to the first position.

[0014] The control device is configured to control each actuation device of the set of actuation devices independently.

[0015] Each mobile support fixing device can receive a maximum of one bottle.

[0016] Each fastening device of a mobile support can remain empty and thus not receive a bottle. In this case, the mobile support in question plays no role in the distribution of liquid.

[0017] When a bottle is received in the corresponding fixing device, the bottle is rigidly attached to the movable support.

[0018] When a movable support is in the second position, known as the flow position, the liquid flowing from the bottle falls into the collection container without coming into contact with any device other than the collection container.

[0019] In other words, the liquid poured from a bottle falls directly into the collection container, without touching any other surface. Since no surface other than that of the collection container comes into contact with the liquid, no cleaning operation is necessary. Furthermore, the risk of contamination from dirt remaining on surfaces is eliminated.

[0020] According to one embodiment of the distribution device, the device for measuring the quantity of liquid distributed includes an optical drop counting system.

[0021] The optical drop counting system includes a laser light emitter and a photodiode for receiving the light emitted by the laser emitter.

[0022] According to one embodiment, or in addition, the device for measuring the quantity of liquid distributed includes a weighing system.

[0023] According to another embodiment, or in a complementary manner, the device for measuring the quantity of liquid distributed includes a system for counting the duration of liquid distribution.

[0024] According to one embodiment of the distribution device, each mobile support is mobile in rotation relative to the frame around an axis.

[0025] Preferably, the axis of rotation of a movable support is substantially horizontal when the liquid distribution device is in a nominal operating position.

[0026] According to an exemplary embodiment of the distribution device, each actuation device comprises: - an electric motor, and - a transmission system linked to the electric motor and configured to drive the mobile support in rotation.

[0027] The mobile support is configured to move from the first position, called the rest position, to the second position, called the flow position, by a rotation along a first direction of rotation of the mobile support.

[0028] The mobile support is configured to move from the second position, called the flow position, to the first position, called the rest position, by a rotation of the mobile support in a direction of rotation opposite to the first direction of rotation.

[0029] According to an example embodiment, all mobile supports are identical.

[0030] According to one embodiment, all the actuation devices are identical.

[0031] In particular, the respective electric motors of the actuation devices are identical.

[0032] The transmission system linking the electric motor to the mobile support may include a reducer.

[0033] According to one embodiment of the distribution device, the electric motor of an actuation device is a servomotor.

[0034] This type of electric motor ensures positional stability without an additional mechanism, such as a brake. Positional stability is naturally ensured by a servomotor, which makes this type of motor particularly suitable for the application intended here.

[0035] The transmission system linking the electric motor to the moving support can be a coupling sleeve.

[0036] The axis of rotation of the electric motor and the axis of rotation of a mobile support are, for example, coaxial.

[0037] According to one embodiment of the distribution device, the control device is configured to control the set of actuation devices sequentially, a control period of each of the actuation devices being disjoint from a control period of the other actuation devices.

[0038] The control device is configured so that only one movable support at a time can be in the second position, known as the flow position.

[0039] According to another embodiment of the distribution device, the control device is configured to control at least two actuation devices of the set of actuation devices simultaneously.

[0040] According to one aspect of the distribution device, each actuation device is configured to move the mobile support from the first position to the second position in less than 2.0 seconds.

[0041] According to another aspect of the dispensing device, each actuation device is configured to move the mobile support from the second position to the first position in less than 2.0 seconds.

[0042] According to one embodiment of the distribution device, each fixing device includes a bottle receiving housing, the receiving housing extending along an axis.

[0043] According to one embodiment of the distribution device, the axis of the bottle receiving housing is perpendicular to the axis of rotation of a movable support.

[0044] According to one embodiment of the dispensing device, a liquid outlet nozzle is coaxial with the axis of the bottle receiving housing, and the axis of the receiving housing of a vial intersects with a straight line joining the laser emitter and the photodiode.

[0045] When the axis of rotation of a movable support is horizontal, with the axis of the bottle's receiving chamber perpendicular to this axis of rotation, and with the liquid dispensing nozzle coaxial with the axis of the receiving chamber, and the axis of the bottle's receiving chamber intercepting the direction of emission of the laser light from the drop counting system, a drop falling from the bottle's nozzle crosses the laser beam regardless of the movable support's angular position. Thus, all drops falling from the bottle are counted.

[0046] According to one embodiment, the distribution device comprises: - a first fluidic unit, comprising: — a first mobile support, — a first actuation device, linked to the first mobile support, - a second fluidic unit, comprising: — a second movable support, — a second actuation device, linked to the second movable support. The first fluidic unit and the second fluidic unit are arranged symmetrically with respect to a vertical axis.

[0047] According to one embodiment, the distribution device comprises: - a third fluidic unit, comprising: — a third mobile support, — a third actuation device, linked to the third mobile support, - a fourth fluidic unit, comprising: — a fourth movable support, — a fourth actuation device, linked to the fourth movable support. The third fluidic unit and the fourth fluidic unit are arranged symmetrically with respect to a vertical axis.

[0048] The two fluidic units of a pair of fluidic units may be identical.

[0049] The distribution device may comprise four identical fluidic units.

[0050] The main components of the distribution device can thus be standardized.

[0051] The axis of symmetry of the first fluidic unit and the second fluidic unit can be identical to the axis of symmetry of the third fluidic unit and the fourth fluidic unit.

[0052] According to one embodiment, the axis of rotation of the first mobile support is perpendicular to the axis of rotation of the third mobile support.

[0053] Similarly, the axis of rotation of the second mobile support is perpendicular to the axis of rotation of the fourth mobile support.

[0054] According to one embodiment of the distribution device, each fastening device includes an elastic snap-fit ​​device.

[0055] The fastening device includes, for example, a C-shaped hook.

[0056] According to one embodiment, each fastening device comprises a wall of base configured to form a stop for the bottom of the bottle.

[0057] The C-shaped hook and the bottom wall extend in parallel planes.

[0058] The C-shaped hook and the bottom wall extend in planes perpendicular to the axis of the bottle receiving housing.

[0059] According to one embodiment of the dispensing device, each fixing device includes an angular indexing device configured to cooperate with an angular indexing device of a bottle so that an angular orientation of the bottle with respect to the moving support corresponds to a predetermined orientation.

[0060] The angular indexing device of a fastening device is formed on the bottom wall of the fastening device.

[0061] According to one embodiment of the distribution device, the frame includes a height adjustment device.

[0062] The height adjustment device allows the liquid dispensing device to be leveled to ensure its horizontality and to compensate for any imperfections in the surface on which the device is placed. Thus, drops of liquid poured from a bottle and falling into the collection container intercept the laser beam, allowing the number of drops poured to be counted.

[0063] According to an embodiment not shown, the dispensing device may include a device for detecting the presence of the set of bottles.

[0064] The distribution device is configured to operate in a first operating mode, called manual mode, in which the control device is configured to be switched on and off manually by a user of the distribution device.

[0065] According to one embodiment, the dispensing device is configured to operate in a second operating mode, called recipe mode, in which the value of the predetermined quantity of liquid to be dispensed by each bottle is stored in a memory of a data storage device.

[0066] According to one embodiment, the distribution device is configured to operate selectively: - in a first operating mode, called manual mode, in which the control device is configured to be manually activated and deactivated by a user of the dispensing device, or - in a second operating mode, called recipe mode, in which the value of the predetermined quantity of liquid to be dispensed by each bottle is stored in a memory of a data storage device.

[0067] The user can thus choose, according to their current needs or preferences, the most suitable operating mode.

[0068] The data storage device may be internal to the liquid distribution device.

[0069] The data storage device may be an external device configured to communicate with the liquid distribution device, for example by a digital communication protocol.

[0070] A method for controlling a liquid distribution device as described above is also proposed, comprising the steps: - activate the control device to move a movable support from the first position to the second position, the movable support containing a bottle containing a liquid, - determine a time evolution of a quantity of liquid distributed, - if the quantity of liquid distributed during a first predetermined time is less than a first predetermined threshold, reactivate the control device so as to move the mobile support to a third position called the accelerated flow position, an inclination with respect to a horizontal axis of the axis of the receiving housing in the third position being greater than an inclination with respect to a horizontal axis of the axis of the receiving housing in the second position.

[0071] When the quantity of liquid dispensed appears to change very slowly, as may be the case with a high-viscosity liquid, the inclination of the bottle is increased to promote flow and increase the velocity of the liquid exiting the bottle. The time required to obtain the preparation is thus reduced.

[0072] The control process may include the step: - move the movable support to the third position, known as the accelerated flow position, - to determine the temporal evolution of a distributed quantity of liquid, - if the quantity of liquid dispensed during a second predetermined period is less than a second predetermined threshold, issue an alert indicating a bottle defect.

[0073] If the quantity of liquid dispensed remains very low even after the bottle has been placed in the accelerated flow position, a problem affecting the bottle is detected and the user is informed.

[0074] The defect in the bottle may be insufficient filling of the bottle.

[0075] The defect in the bottle may be a partial or total blockage of the bottle tip.

[0076] When the bottle has a vent, the defect in the bottle may be a partial or total blockage of the bottle vent.

[0077] The warning signal may be a light signal, such as the lighting of a warning light.

[0078] The liquid dispensing device may include a single warning light.

[0079] The liquid dispensing device may include a warning light for each mobile support, in other words for each bottle.

[0080] The warning signal may be an audible signal.

[0081] The liquid distribution device may include a sound emitter.

[0082] A bottle for a liquid dispensing device is also proposed, the bottle containing: - a storage container for a liquid, - a liquid dispensing nozzle, - a vent configured to form an air inlet passage into the bottle separate from the dispensing nozzle, - a portion of a cap's fixing mechanism, - an angular indexing device configured to cooperate with an angular indexing device of a fixing device so that an angular orientation of the bottle relative to the moving support corresponds to a predetermined orientation.

[0083] The bottle storage enclosure is cylindrical in shape.

[0084] The angular indexing device of the bottle includes a protruding portion and the angular indexing device of the fixing device includes a cavity for receiving the protruding portion.

[0085] The protruding portion and the receiving cavity have a complementary shape.

[0086] The protruding portion of the bottle is arranged on a bottom wall of the bottle.

[0087] The liquid outlet is coaxial with the axis of the liquid storage chamber.

[0088] The nozzle and vent are formed on a cap that closes an opening in the bottle's enclosure.

[0089] The predetermined orientation is an orientation in which, when the movable support is in the second position called the flow position, the height of the vent is greater than the height of the nozzle.

[0090] Thus, the vent can remain clear, i.e. not covered by the liquid, while the liquid flows from the bottle. Brief description of the drawings

[0091] Other features, details and advantages will become apparent upon reading the detailed description below, and upon analysis of the accompanying drawings, on which:

[0102] To facilitate reading the figures, the different elements are not necessarily drawn to scale. In these figures, identical elements bear the same reference numerals. Certain elements or parameters may be indexed, that is, designated, for example, as first element or second element, or first parameter and second parameter, etc. This indexing aims to differentiate similar, but not identical, elements or parameters. This indexing does not imply a priority of one element or parameter over another, and the designations may be interchanged.

[0103] The expression "a second element is placed between a first element and a third element" means that the shortest path to go from the first element to the third element or from the third element to the first element passes through the second element.

[0104] When it is specified that a subsystem includes a given element, this does not exclude the presence of other elements in that subsystem.

[0105] In the figures, the X, Y, and Z axes denote the three directions of space. The Z axis designates the vertical axis, that is, the vertical direction. The X and Y axes extend in a horizontal plane.

[0106] Figure [Fig.1] shows a distribution device 100 for liquids contained in a set of bottles 30-1, 30-2, 30-3, 30-4. Liquid distribution refers to the act of supplying different liquids in order to obtain a liquid solution of a desired composition. The 100 dispensing device allows the preparation of a liquid solution by mixing the liquid products contained in each of the bottles provided. The preparation could, for example, be a preparation of essential oils, but other applications are of course possible. The 100 dispensing device allows for a preparation with a precisely adjusted composition, with a total quantity of prepared solution corresponding to a quantity desired by the user.

[0107] The device for dispensing liquids 100 from a set of bottles 30-1, 30-2, ..., 30-N comprises: - a frame 1, - a set of supports 2-1, 2-2, ..., 2-N movable relative to the frame 1, each movable support 2-k comprising a fastening device 3-k configured to receive a bottle 30-k containing a liquid Lk, in which each movable support 2-k can be moved between: a first position PI, called the rest position, in which the liquid Lk remains contained in the bottle 30-k, and a second position P2, called the flow position, in which the liquid Lk flows from the bottle 30-k so as to distribute the liquid Lk towards a collection container 40, - a set of actuation devices 4-1, 4-2, ..., 4-N, each actuation device 4-k being configured to selectively move a movable support 2-k between the first position PI and the second position P2, - a control device 5 of the set of actuation devices 4-1, 4-2, ..., 4-N configured to start and stop a flow of liquid from each bottle 30-k.

[0108] The index k is a positive integer denoting the index number of an element in a set of N elements. The index k therefore varies from 1 to N. The first The first element corresponds to the value 1 of the index k, the second element corresponds to the value 2 of the index k, etc. In the illustrated example, the liquid dispensing device 100 comprises four movable supports, each of which can hold one bottle. In other words, N=4 in the illustrated example. The index k, designating the rank number of each device, can therefore vary from 1 to 4.

[0109] In Figures 2, 8, and 9, which represent one of the four elements included in the device 100, the index k has not been mentioned. The element represented in these figures can be any one of the four elements of the device 100.

[0110] The frame 1 forms an enclosure in which the various components of the distribution device 100 are received. The frame 1 also forms a support for the various components. In the illustrated example, frame 1 is generally parallelepiped in shape, but other shapes can be used. The frame 1 of the appliance is placed on the surface of a support 45, which can be, for example, a worktop. The frame 1 can also be placed on the floor. [YES] In the schematic [Fig.1], the liquid L1, L-2, L-3, L-4 contained respectively in the bottles 30-1, 30-2, 30-3, 30-4 flows into the collection container 40. The symbol V designates the volume of liquid already poured into the collection container 40. The symbol T designates the free surface of the volume of liquid already poured. The symbols Gl, ..., G-4 schematically show the drops of liquids Ll, ​​L-2, L-3, L-4 flowing respectively from the different bottles 30-1, 30-2, 30-3, 30-4.

[0112] Each support 2-1, 2-2, 2-3, 2-4 of the dispensing device can respectively receive a bottle 30-1, 30-2, 30-3, 30-4, each bottle containing a liquid product to be incorporated into a mixture to be prepared. Each liquid to be dispensed to make the desired preparation is poured directly from the bottle containing that product. A control device 5 allows the flow of liquid to be started and stopped in order to obtain a desired quantity of liquid.

[0113] Figure 7 illustrates an example of a bottle used in the dispensing device 100.

[0114] The bottle 30 comprises: - a container 31 for storing a liquid, - a 32mm liquid outlet, - a vent 33 configured to form an air inlet passage into the bottle 30 separate from the dispensing nozzle 32, - a portion of the fixing 34 of a cap, not shown in this figure.

[0115] The enclosure 31 is sealed and forms a storage volume for a liquid. The nozzle 32 is integral with the sealed enclosure 31, and forms a channel for the liquid to flow out of the enclosure 31-k. Bottle 30, for example, is made of glass. Following the example in [Fig.7], bottle 30 is generally cylindrical in shape.

[0116] Fig. 2 illustrates the process of distributing liquid from a given bottle 30.

[0117] In the first position PI, referred to as the rest position, the liquid L remains contained within the bottle 30, because the height H1 along the vertical axis Z of the free surface S of the liquid in the enclosure 31 is less than the height H2 of the nozzle 32. This position is shown schematically in part A of [Fig. 2]. The bottle is oriented parallel to the vertical axis Z. Part B schematically shows the position of the bottle 30 during a stroke of displacement of the bottle by the actuation device 4. The bottle is inclined with respect to the vertical axis Z. Part C schematically represents the position of the bottle when it is in the second position P2, known as the flow position. The inclination of the bottle 30° relative to the vertical axis In the second position P2, called the flow position, the liquid L flows from the bottle 30k, because the height Hl' of the free surface of the liquid in the enclosure 31 is greater than the height H2' of the nozzle 32. The product contained in the bottle flows out of the bottle 30 and falls into the collection container 40. The collection container 40 can have any shape, as long as its opening allows the liquid flowing from the bottles to be collected and its capacity is suitable for the amount of liquid to be poured. The collection container 40 is unique here, meaning that all poured liquids flow into the same collection container. However, it is possible to use several collection containers simultaneously, for example in order to carry out several simple preparations in parallel involving a small number of different liquids.

[0118] Height is defined as the elevation along a vertical axis Z oriented from bottom to top. Under the action of gravity, an object naturally moves from the highest height to the lowest height. The free surface S of the liquid in the bottle 30 is defined as the interface between the liquid contained in the bottle and the layer of air covering the liquid. The position and shape of the free surface S of the liquid vary with the fill level of the bottle, as well as with the orientation of the bottle 30 relative to the horizontal axis X.

[0119] In the second position P2, called the flow position, the liquid L contained in a bottle 30 flows by gravity.

[0120] According to the illustrated example, the dispensing device 100 includes a measuring device 6 for a quantity Qk of liquid dispensed by each bottle 30-k, and the dispensing device 100 is configured so that a quantity Qk of liquid dispensed by each bottle 30-k is equal to a predetermined quantity Ck.

[0121] The control device 5 is configured to control each actuating device 4-k of the set of actuating devices 4-1, 4-2, ..., 4-N so as to trigger the flow of the liquid contained in the bottle 30-k. To do this, the 4-k actuation device moves the 2-k mobile support from the first position PI to the second position P2.

[0122] The control device 5 is also configured to control each actuating device 4-k of the set of actuating devices 4-1, 4-2, ..., 4-N so as to interrupt the flow of the liquid contained in the bottle 30-k. To do this, the 4-k actuation device moves the 2-k mobile support from the second position PI to the first position P2.

[0123] A bottle is thus moved from the first position PI to the second position P2 to carry out the distribution of the liquid contained in this bottle, and the bottle is returned to the first position PI once the desired quantity of liquid has been obtained.

[0124] The control device 5 is configured to control each actuating device 4-k of the set of actuating devices 4-1, 4-2, ..., 4-N independently.

[0125] Each 3-k fixing device of a 2-k mobile support can receive a maximum of one 30-k bottle. When the desired preparation includes fewer different liquids than available carriers, each 3-k fixing device on a 2-k mobile carrier can remain empty and thus not receive a bottle. In this case, the mobile carrier in question plays no role in liquid dispensing.

[0126] When a 30-k vial is received in the corresponding 3-k fixing device, the 30-k vial is rigidly connected to the 2-k mobile support.

[0127] Rigidly bound means that the bottle 30-k has no degree of kinematic freedom with respect to the mobile support 2-k, for a level of mechanical stress corresponding to normal use of the dispensing device 100. In other words, a displacement of a mobile support 2-k causes a corresponding displacement of the bottle 30-k received in the fixing device 3-k.

[0128] When a movable support 2-k is in the second position P2, called the flow position, the liquid flowing from the bottle 30-k falls into the collection container 40 without coming into contact with any other device than the collection container 40.

[0129] The liquid poured from a bottle 30-k falls directly into the collection container 40, without touching any other wall. As no other wall than that of the Since the collection container 40 does not come into contact with the liquid, no cleaning of the dispensing device is necessary. Furthermore, the risk of contamination of the prepared mixture by dirt or contaminants remaining on the walls of the dispensing device is eliminated.

[0130] Different types of devices for measuring the quantity of liquid dispensed can be used.

[0131] According to the illustrated example, the device 6 for measuring the quantity of liquid distributed includes an optical drop counting system.

[0132] The optical drop counting system includes a laser light emitter 7 and a photodiode 8 for receiving the light emitted by the laser emitter 7.

[0133] The photodiode 8 outputs a first level of electrical signal when it receives the light beam emitted by the laser emitter 7. The photodiode 8 outputs a second level of electrical signal when it does not receive laser light. When a droplet G of liquid passes through the emitted laser light beam, the photodiode 8 stops receiving light. After the droplet G has passed through, the photodiode 8 resumes receiving light. The transitions of the electrical signal output by the photodiode 8 during a given time interval allow the number of drops that have passed through the laser beam during that time interval to be counted. Counting the number of drops poured allows for an accurate determination of the volume poured. The flow of liquid from the bottles is discontinuous in this example. In other words, the drops of liquid pass one after another through the laser beam, and a non-zero time interval separates the passage of two successive drops.

[0134] According to an embodiment not shown, the device 6 for measuring the quantity of liquid dispensed includes a weighing system.

[0135] According to this variant, the liquid collection container 40, as well as the liquid contained in the collection container 40, are weighed at successive times when a bottle 30-k is in flow position P2. Monitoring the temporal evolution of the cumulative mass of the collection container 40 and of the liquid contained in this collection container 40 makes it possible to determine the quantity of liquid distributed in the collection container 40. This weighing system can replace the optical drop counting system. It can also be used in conjunction with, or as a complement to, the optical drop counting system.

[0136] According to another embodiment not shown, the device for measuring the quantity of liquid distributed includes a system for counting the duration of liquid distribution.

[0137] In this case, the quantity of liquid dispensed by a bottle is determined from the time during which this bottle is held in the flow position P2, and from an instantaneous flow model of liquid flowing from the bottle. A duration corresponding to the time required to obtain the desired quantity of liquid is determined, and the bottle is returned to the resting position once this flow time has been reached. Such a device for measuring the quantity of liquid dispensed is mainly applicable to applications where the volumes to be prepared are too large to implement drop counting.

[0138] Each mobile support 2-k is here mobile in rotation relative to the frame 1 around an axis Ak. Preferably, the rotation axis Ak of ​​a mobile support 2-k is substantially horizontal when the liquid distribution device 100 is in a nominal operating position. Each 4-k actuation device includes: - a 9k electric motor, and - a 10-k transmission system linked to the 9-k electric motor and configured to drive the 2-k mobile support in rotation.

[0139] The actuating device 4-k is configured to selectively drive the mobile support 2-k in a first direction of rotation or in a second direction of rotation opposite to the first direction of rotation. In other words, the control device 5 allows you to select the desired direction of rotation for the mobile support 2-k.

[0140] The mobile support 2-k is configured to move from the first position PI, called the rest position, to the second position P2, called the flow position, by a rotation along a first direction of rotation of the mobile support 2-k. A rotation of the mobile support 2-k in a first direction of rotation triggers the flow of liquid out of the bottle.

[0141] The movable support 2-k is configured to move from the second position P2, known as the flow position, to the first position PI, known as the rest position, by rotating the movable support 2-k in the opposite direction to the first direction of rotation. In other words, a rotation in the opposite direction to the first direction of rotation stops the flow of liquid out of the bottle.

[0142] According to the illustrated example, all the movable supports 2-1, 2-2, ..., 2-N are identical. Similarly, all the actuation devices 4-1, 4-2, ..., 4-N are identical. Similarly, the electric motors 9-1, 9-2, ..., 9-N respective of the actuation devices 4-1, 4-2, ..., 4-N are identical.

[0143] According to an unshown variant, the liquid dispensing device 100 may include a support 2-j that differs from the other supports. This configuration may, for example, be used when one of the bottles has a different capacity and dimensions than the other bottles.

[0144] According to variants not shown, the transmission system 10-k linking the electric motor 9-k to the mobile support 2-k may include a reducer. In other words, the kinematic link between the output shaft of the electric motor and the moving support can include a gear train, or a worm and pinion system.

[0145] According to the illustrated example, the electric motor 9-k of an actuation device 4-k is a servomotor. The use of a servo motor allows the 4-k actuation device to be held in position without adding an additional mechanism such as a brake.

[0146] The transmission system 10-k linking the electric motor 9-k to the mobile support 2-k can be a coupling sleeve.

[0147] The rotation axis Bk of the electric motor 9-k and the rotation axis Ak of ​​a movable support 2-k are here coaxial. The shaft of the electric motor 9-k is, for example, inserted into a receiving housing of the mobile support 2-k. The receiving housing has a shape complementary to the shape of the shaft.

[0148] According to the illustrated example, the control device 5 is configured to control the set of actuation devices 4-1, 4-2, ..., 4-N sequentially, a control period of each of the actuation devices 4-1, 4-2, ..., 4-N being disjoint from a control period of the other actuation devices.

[0149] The control device 5 is configured so that only one mobile support 2-k at a time can be in the second position P2, the so-called flow position.

[0150] In other words, the control periods of each of the actuation devices 4-1, 4-2, ..., 4-N do not overlap. A control period of an actuation device 4-k does not overlap with a control period of any of the other actuation devices in the set of actuation devices 4-1, 4-2, ..., 4-N. The liquid is dispensed in turn from each 30-k vial until all the vials required for the desired preparation have been used. The liquid dispensing from a given vial begins once the liquid dispensing from the previous vial is complete.

[0151] Fig. 3 schematically illustrates the sequential control of a first actuation device 4-1, in which a first bottle 30-1 is fixed, and of a second actuation device 4-2, in which a second bottle 30-2 is fixed. The first bottle 30-1 contains a first liquid L1 and the second bottle 30-2 contains a second liquid L-2. Diagrams A through D are in chronological order.

[0152] In part A, the first bottle 4-1 and the second bottle 4-2 are both in the rest position PI. The first bottle 4-1 begins its movement towards the flow position P2, the direction of movement being schematically indicated by the curved arrow. The second 4-2 bottle is stationary. On part B, the first bottle 4-1 has reached the flow position P2, and drops Gl of the first liquid L1 flow into the collection container 40. In section C, the liquid distribution from the first bottle 4-1 is complete, and the first bottle 4-1 has returned to its resting position PI. The second bottle 4-2 begins its movement towards the flow position P2, the direction of movement being indicated by the curved arrow. In part D, the second bottle 4-2 is in the flow position P2, and the liquid from the second bottle 4-2 is being dispensed. Drops G-2 of the second liquid L-2 fall one after another into the collection container 40. When the desired quantity of the second liquid L-2 has been poured, the second bottle 30-2 is brought back into the first position PI, and the whole is in a configuration identical to that of part A of [Fig.3].

[0153] According to another embodiment of the distribution device 100, the control device 5 is configured to control at least two actuation devices 4-i, 4-j of the set of actuation devices 4-1, 4-2, ..., 4-N simultaneously.

[0154] Each actuating device 4-k is configured to move the mobile support 2-k from the first position PI to the second position P2 in less than 2.0 seconds. Furthermore, each actuating device 4-k is configured to move the mobile support 2-k from the second position P2 to the first position PI in less than 2.0 seconds.

[0155] The tipping phases of the bottles are thus sufficiently distinct to ensure good repeatability of the drop size. Unwanted liquid flow, for example at the end of the pouring phase, is avoided.

[0156] Fig. 10 illustrates the operation of the distribution device 100. On part A of [Fig.10], the curve M1 illustrates the evolution over time of the position of the mobile support, reflecting the inclination of the bottle, the curve M2 illustrates the evolution over time of the quantity Q of liquid poured, and the curve M3 illustrates the logic state of the control of the electric motor of the mobile support.

[0157] At the initial instant, the angle of inclination of the mobile support has the value anl, corresponding to the rest position PI. At time t1, the electric motor is activated, as shown by curve M3, and the tilt angle of the moving support begins to increase. At time t2, the tilt angle reaches the value an2, which corresponds to the flow position P2. From time t2, drops of liquid flow from the bottle, and the quantity poured Q increases. Each square on the curve M2 corresponds to the passage of one drop. At time t4, the desired quantity of liquid C is reached. The bottle begins to move back to its initial position. At time t5, the moving support has returned to its initial position, corresponding to its rest position. The electric motor is then switched off. A pouring of liquid from another bottle, not shown, can continue.

[0158] Each 3-k fixing device includes an 11-k housing for receiving a 30-k bottle, the 11-k receiving housing extending along an axis Dk. According to the example illustrated in particular on [Fig.8], the axis Dk of the receiving housing 11-k of a bottle 30-k is perpendicular to the axis of rotation Ak of ​​a mobile support 2-k.

[0159] During the rotation of the movable support 2-k from the first position PI, known as the rest position, to the second position P2, known as the flow position, all successive positions of the axis Dk of the receiving housing 11-k of a bottle 30-k lie within a plane. This plane is perpendicular to the axis of rotation Ak of ​​the movable support 2-k.

[0160] According to the illustrated example, particularly in [Fig.2] and [Fig.9], a 32-k outlet for the liquid from the 30-k bottle is coaxial with the axis Dk of the receiving housing 11-k of a 30-k bottle, and the axis Dk of the receiving housing 11-k of a 30-k vial is secant with a straight line R joining the laser emitter 7 and the photodiode 8.

[0161] When the rotation axis Ak of ​​a movable support 2-k is horizontal, with the axis Dk of the receiving housing 11-k of a bottle 30-k perpendicular to this rotation axis Ak, and with the liquid outlet 32 ​​coaxial with the axis Dk of the receiving housing 11-k, and the axis Dk of the receiving housing 11-k of a bottle 30-k intercepting the direction of emission of the laser light from the drop counting system, a drop falling from the outlet 32 ​​of the bottle crosses the laser beam regardless of the angular position of the movable support 2-k. The exact angular position of the movable support at the moment a drop exits the bottle has no influence on the counting. drops. Thus, all the drops falling from the 30-k bottle are counted by the optical drop counting device.

[0162] Figure 5 details the relative arrangement of several fluidic units. A fluidic unit forms a module comprising the elements necessary for the handling of a given bottle.

[0163] According to the illustrated embodiment, the distribution device 100 comprises a first fluidic unit 20-1 and a second fluidic unit 20-2. The first fluidic unit 20-1 includes a first movable support 2-1, and a first actuation device 4-1 linked to the first movable support 2-1. The second fluidic unit 20-2 includes a second movable support 2-2 and a second actuation device 4-2, linked to the second movable support 2-2. The first fluidic unit 20-1 and the second fluidic unit 20-2 are arranged symmetrically with respect to a vertical axis Z.

[0164] In other words, the figure formed by the first fluidic unit 20-1 and the second fluidic unit 20-2 is invariant under a rotation of 180° around a vertical axis. The axis of rotation Al of the first mobile support 2-1 is parallel to the axis of rotation A-2 of the second mobile support 2-2. The plane defined by the axis of rotation of the first mobile support 2-1 and by the axis of rotation of the second mobile support 2-2 is here perpendicular to the vertical axis Z.

[0165] In [Fig.5], the distribution device 100 comprises a third fluidic unit 20-3 and a fourth fluidic unit 20-4. The third fluidic unit 20-3 includes a third movable support 3-1 and a third actuation device 4-3, linked to the third movable support 2-3. The fourth fluidic unit 20-4 includes a fourth movable support 2-2 and a fourth actuation device 4-2, linked to the fourth movable support 2-2. The third fluidic unit 20-3 and the fourth fluidic unit 20-4 are arranged symmetrically with respect to a vertical axis Z.

[0166] The axis of rotation of the third mobile support 2-3 is parallel with the axis of rotation of the fourth mobile support 2-4.

[0167] The axis of symmetry of the first fluidic unit 20-1 and of the second fluidic unit 20-2 is here identical to the axis of symmetry of the third fluidic unit 20-3 and of the fourth fluidic unit 20-4.

[0168] According to the example in [Fig.5], the axis of rotation Al of the first mobile support 2-1 is perpendicular to the axis of rotation of the third mobile support 2-3. Similarly, the axis of rotation of the second mobile support 2-2 is perpendicular to the axis of rotation of the fourth mobile support 2-4.

[0169] Viewed along a vertical axis Z, the figure formed by the first 20-1, the second 20-2, the third 20-3 and the fourth fluidic unit 20-4 is invariant under a rotation of 90°. In other words, a 90° rotation around a vertical axis allows one to go from one given fluidic unit to another fluidic unit. The center C of the collection container 40 can be aligned, along the vertical axis Z, with the center of rotation allowing passage from one fluidic unit to another. This arrangement allows for a particularly compact layout and thus limits the footprint of the distribution device 100.

[0170] The two fluidic units of a pair of fluidic units may be identical. The first fluidic unit 20-1 can thus be identical to the second fluidic unit 20-2. Similarly, the third fluidic unit 20-3 can thus be identical to the fourth fluidic unit 20-4. Preferably, the distribution device 100 comprises four identical fluidic units. The main components of the 100 distribution device can thus be standardized.

[0171] Each fluidic unit 20-1, 20-2, 20-3, 20-4 is secured to the frame 1, respectively by a fixing 25-1, 25-2, 25-3, 25-4. The fixing can for example be a mechanical profile. Each fluidic unit is rigidly linked to frame 1.

[0172] The liquid quantity measurement device 6 comprises a first unit for determining the quantity of liquid supplied by two fluidic units, and a second unit for determining the quantity of liquid supplied by the other two fluidic units.

[0173] For this purpose, a first laser beam is used to count the drops coming from the first fluidic unit 20-1 and the second fluidic unit 20-2. The distribution device 100 thus comprises a first laser emitter 7 and a first photodiode 8 receiving the light emitted by the first emitter 7. A second laser beam allows for counting the drops coming from the third fluidic unit 20-3 and the fourth fluidic unit 20-4. The distribution device 100 includes a second laser emitter 7' and a second photodiode 8' receiving the light emitted by the first emitter 7.

[0174] The first laser emitter 7 and the second laser emitter 7' may be identical. The first photodiode 8 and the second photodiode 8' may be identical. Signal processing is thus facilitated.

[0175] Figures 8 and 9 detail the installation of a bottle 30 in a corresponding fixing device 3. In [Fig. 8], bottle 30 is not installed. In [Fig. 9], bottle 30 is installed.

[0176] According to the embodiment of the dispensing device 100, each 3-k fixing device includes a spring-loaded snap-fit ​​device.

[0177] The 3-k fastening device includes, for example, a C-shaped 12-k hook. The 12-k hook surrounds a portion of an outer surface of the bottle 30. The 12-k hook can elastically deform during the insertion of the vial 30. The 12-k hook returns to its original shape once the vial is inserted, and prevents the vial 30 from accidentally detaching.

[0178] Each 3-k fixing device includes a 13-k bottom wall configured to form a stop for a 30-k bottle bottom.

[0179] The C-shaped hook 12-k and the bottom wall 13-k extend in parallel planes. The C-shaped hook 12-k and the bottom wall 13-k extend in planes PI, P2 perpendicular to the axis Dk of the receiving housing 11-k for a bottle 30-k.

[0180] The bottom wall 13-k is in the shape of a half-disk. Since the bottle 30 is in the shape of a cylinder of revolution, half of the bottom of the bottle 30 rests on the bottom wall 13 when the bottle 30 is placed in its receiving housing 11.

[0181] According to an embodiment of the dispensing device 100 (not shown), each fastening device 3-k includes an angular indexing device configured to cooperate with an angular indexing device of a bottle 30-k so that an angular orientation of the bottle 30-k relative to the movable support 2-k corresponds to a predetermined orientation.

[0182] The angular indexing device of a 3-k fixing device is for example formed on the bottom wall 13-k of the 3-k fixing device. The angular indexing device of a 3-k fixation device includes, for example, a receiving cavity, and the angular indexing device of a 30-k vial includes a projecting portion that can be inserted into the receiving cavity. The receiving cavity is offset from the axis of the bottom wall 13-k, so that the vial 30-k can be inserted into the fixing device 3-k according to a single angular orientation.

[0183] According to one embodiment of the distribution device 100, the frame 1 includes a height adjustment device 15.

[0184] The height adjustment device 15 allows the level of the liquid dispensing device 100 to be adjusted to ensure its horizontality and compensate for any imperfections in the support 45 on which the device 100 is placed. Thus, the drops of liquid poured from a bottle 30-k and falling into the collection container 40 reliably intercept the laser beam, allowing the number of drops dispensed to be counted. The risk of missing the droplet count is eliminated.

[0185] According to one embodiment, the dispensing device 100 includes a device for detecting the presence of the set of bottles 30-1, 30-2, ..., 30-N. The presence detection device prevents starting a preparation when one or more bottles have not been inserted into the device. The presence detection device was not shown in the various figures.

[0186] The dispensing device 100 can operate according to several operating modes.

[0187] According to one embodiment, the distribution device 100 is configured to operate in a first operating mode, called manual mode, in which the control device 5 is configured to be manually activated and deactivated by a user of the distribution device 100.

[0188] In this so-called manual operating mode, the operator starts the flow of liquid from a bottle, maintains the flow until a desired quantity is reached, and stops the distribution of liquid himself when the desired quantity of the product contained in this bottle corresponds to the desired quantity. The operator then repeats the operation for a second bottle, then a third if necessary, until all the desired products have been distributed. The operator can monitor the evolution of the quantity dispensed in real time, in order to know when to stop the distribution of the product from each bottle. In other words, the user interrupts the distribution of liquid from a bottle when he judges that the predetermined quantity Ck of liquid to be distributed by each bottle 30-k has been reached.

[0189] According to another embodiment, the dispensing device 100 is configured to operate in a second operating mode, called recipe mode, in which the value of the predetermined quantity Ck of liquid to be dispensed by each bottle 30-k is stored in a memory of a data storage device.

[0190] The same device 100 can operate on demand according to either manual mode or recipe mode.

[0191] Thus, the dispensing device 100 can be configured to operate selectively: - in a first operating mode, called manual mode, in which the control device 5 is configured to be manually activated and deactivated by a user of the distribution device 100, or - in a second operating mode, called recipe mode, in which the value of the predetermined quantity Ck of liquid to be distributed by each 30-k bottle is stored in a memory of a data storage device.

[0192] The user can thus choose, according to their current needs or preferences, the most suitable operating mode.

[0193] The data storage device 20 may be internal to the liquid distribution device 100.

[0194] The data storage device 20 may be an external device configured to communicate with the liquid dispensing device 100, for example by a digital communication protocol. The storage of data enabling the reproduction of a desired recipe, that is to say a preparation having the desired composition and the desired quantity, can for example be carried out using an application operated by a mobile phone, a tablet, or a computer. Other means of storing data indicating the quantities to be poured of the different products can of course be used.

[0195] A method for controlling a liquid dispensing device 100 as described above is also proposed, comprising the steps: - activate the control device 5 so as to move a mobile support 2-k from the first position PI to the second position P2, the mobile support 2-k having a bottle 30-k containing a liquid Lk, - determine a time evolution of a quantity Qk of liquid distributed, - if the quantity Qk of liquid distributed during a first predetermined time Tl is less than a first predetermined threshold SI, reactivate the control device 5 so as to move the mobile support 2-k to a third position P3 called the accelerated flow position, an inclination with respect to a horizontal axis of the axis Dk of the receiving housing 1 lk in the third position P3 being greater than an inclination with respect to a horizontal axis of the axis Dk of the receiving housing 1 lk in the second position P2.

[0196] When the quantity Qk of liquid delivered appears to evolve very slowly, as may be the case with a high-viscosity liquid, the inclination of the bottle is increased to promote the flow of the liquid and increase the exit velocity. The time required to obtain the preparation is thus reduced.

[0197] The third position P3, known as the accelerated flow position, can correspond to a position in which the bottle is vertical, with the nozzle 32 pointing downwards. This position corresponds to the position in which the force of gravity is most favorable to the flow of the liquid out of the bottle.

[0198] The control process may include the step: - move the mobile support 2-k to the third position P3, known as the accelerated flow position, - to determine the temporal evolution of a distributed quantity Qk of liquid, - if the quantity Qk of liquid dispensed during a second predetermined duration T2 is less than a second predetermined threshold S2, issue an alert indicating a defect in the bottle.

[0199] If the quantity of liquid dispensed remains very low even after the bottle has been placed in the P3 accelerated flow position, a problem affecting the bottle is detected and the user is informed.

[0200] The defect in the bottle may be insufficient filling of the bottle. In other words, the bottle is empty, or about to be empty.

[0201] The defect in the bottle may be a partial or total blockage of the bottle tip. In this case, even if the bottle is sufficiently filled, the liquid flow is incorrect.

[0202] When the bottle has a vent, the defect in the bottle may be a partial or total blockage of the bottle vent.

[0203] The warning signal may be a light signal, such as the lighting of a warning light.

[0204] The 100 liquid dispensing device may include a single warning light. The 100 liquid dispensing device may include an alert light for each 2-k mobile support, in other words for each 30-k bottle.

[0205] The warning signal can also be an audible signal. The liquid dispensing device 100 in this case includes an audible alarm. The alarm is triggered when a fault in the bottle is detected.

[0206] Fig. 10 illustrates the operation of the distribution device 100. Part B of [Fig. 10] illustrates the operation of the distribution device 100 in a case where the accelerated flow position P3 is used. Curve Ml' illustrates the evolution over time of the position of the mobile support, reflecting the inclination of the bottle. Curve M2' illustrates the evolution over time of the quantity Q of liquid poured. Curve M3' illustrates the logic state of the control of the electric motor of the mobile support.

[0207] At the initial instant, the angle of inclination of the moving support has a value of anl, corresponding to the rest position PL At time t1', the electric motor control starts, curve M3', and the angle of inclination of the moving support begins to increase. At time t2', the angle of inclination reaches the value an2, corresponding to the flow position P2. From time t2', drops of liquid flow from the bottle, and the quantity poured Q increases, each time slot corresponding to the passage of one drop. At time t3', the duration T1 is reached. At this instant, the quantity poured is less than the first predetermined threshold SI. The angle of inclination of the moving support is therefore increased again, and reaches at time t4' a value an3 corresponding to the accelerated flow position P3. The quantity poured Q continues to increase, more rapidly than before. Time t5' corresponds to the end of the second predetermined duration T2. ​​At this time, the quantity paid is greater than the second predetermined threshold S2. Therefore, no alert signal is issued. At time t6', the desired quantity of liquid C is reached. The bottle begins to be returned to its initial position. At time t7', the moving support has returned to its initial position and the electric motor control is stopped, curve M3'.

[0208] By comparison, in the case of part A of [Fig. 10], the quantity paid Q is greater, at time t3, than the first predetermined threshold SL. This time t3 corresponds to the moment when the order duration Tl is reached. Liquid distribution therefore continues without using the accelerated flow position P3.

[0209] A 30 bottle is also proposed for a 100 liquid dispensing device. This bottle, number 30, of a particular type, contains: - a container 31 for storing a liquid, - a 32mm liquid outlet, - a vent 33 configured to form an air inlet passage into the bottle 30 separate from the dispensing nozzle 32, - a portion of the fixing 34 of a cap, - an angular indexing device configured to cooperate with an angular indexing device of a 3-k fixing device so that an angular orientation of the bottle 30 with respect to the mobile support 2-k corresponds to a predetermined orientation.

[0210] The storage enclosure 31 for the bottle 30 is here cylindrical in shape.

[0211] The angular indexing device of the bottle 30 comprises a projecting portion and the angular indexing device of the 3-k fixing device includes a receiving cavity for the protruding portion. The protruding portion and the receiving cavity have a complementary shape.

[0212] The protruding portion of the bottle 30 is disposed on a bottom wall of the bottle 30. The liquid outlet 32 ​​is coaxial with the axis E of the liquid storage chamber 31. The nozzle 32 and the vent 33 are formed on a cap 37 closing an opening 38 of the chamber 31 of the bottle 30.

[0213] The predetermined orientation is an orientation in which, when the movable support 2-k is in the second position P2, called the flow position, the height of the vent 33 is greater than the height of the nozzle 32-k. Thus, the vent can remain clear, i.e. not covered by the liquid, while the liquid flows from the bottle. This ensures that air enters the bottle through an opening other than the one through which the liquid flows out of the bottle.

[0214] When the desired preparation comprises more different liquids than vial holders, this preparation can be fractionated. Thus, in the illustrated example where the capacity of the device is four bottles, the first four liquids can be poured without operator intervention in loading the device. The bottles for which the desired quantity has already been dispensed can then be disassembled and replaced with other bottles containing the remaining liquids to be poured. It is not necessary to move the collection container 40 when replacing the vials, which limits the risk of contaminating the already prepared solution. The pouring of the remaining liquids can then be restarted. In the case of preparations involving the mixing of a large number of different liquids, the bottles can be replaced several times in succession, until all the products necessary to obtain the desired preparation are obtained. Because the various ingredients flow directly into the collection container 40, no rinsing is required when changing bottles. Complex preparations can therefore be obtained easily and quickly.
