Description

The invention relates to a device for the storage and distribution of liquid products stored in containers equipped with metering valves.

It relates more particularly to a device for the storage and distribution of liquid products, comprising: - a movable valve holder support, - a valve cleaning system coupled to a support structure, said cleaning system comprising an enclosure, a cleaning member. housed inside the enclosure, means for driving the cleaning member in movement inside said enclosure, said enclosure being suitable for being filled with a cleaning solution for at least partial immersion of the cleaning member inside said solution.

The invention finds a particularly advantageous application in the field of storage, selection and dosage of base colors for paint, in particular for paints prepared on demand by automobile repair professionals.

In this field, bodybuilders develop the quantities of paint necessary for repairing a bodywork by mixing a certain number of base colors.

Each mixture is determined from a formula defined by the paint manufacturer, this formula giving the mass of each base shade to be incorporated for a given quantity of mixture to be obtained.

This preparation commonly involves mixing five to six base shades to achieve the particular shade prescribed by the paint manufacturer.

2 To carry out these operations, a rotary device for dispensing liquid products comprising a plurality of containers storing different respective base colors is known as illustrated for example by patents FR 2 983 089 or EP 2 651 574.

A container 5 comprises, for example, a cell defining a closed interior volume sealingly housing a deformable pocket containing one of the base colors.

Each bag is provided with a metering valve allowing the expulsion of the corresponding base shade towards a collecting container of a metering station of the device when the interior volume of the cell is pressurized and the valve is open.

The containers are fixed, in a circumferential configuration, on a carousel with a horizontal axis of rotation.

The carousel is indexed in rotation so that the metering valve of a selected container is brought into a pick-up position, opposite the collecting container.

Metering means then control the expulsion of a predetermined dose of color into the collecting container.

The metering valves are disposed along the carousel in one or more parallel circumferential rows, the valves in each row describing a circular path when the carousel of the dispensing device is rotated.

A metering valve comprises a conduit terminated by an end, generally of spherical shape, pierced with a passage hole communicating with the interior of the deformable bag so as to allow the expulsion towards the collecting container of the base color. contained in the pocket.

The through hole can be opened or closed at will by means of a shutter coupled to an electromagnetic coil placed around the valve duct and able to drive the shutter in a translational movement parallel to the duct under the action of the means. the aforementioned dosage.

In practice, it is observed that after sampling, traces of paint may remain on the spherical end of the valve at the level of the through hole and of the shutter.

On drying, this dirt runs the risk of blocking the passage hole and therefore of causing metering problems associated with a valve 5, the passage hole of which is partially or completely blocked.

To this are added the projections of paint coming from splashes when the dose of paint is ejected into the collecting container, which can contaminate the valve.

In particular, such projections are liable to pose operating problems of the device by fouling the valve duct at the level of the coil, which may cause sticking, or even tearing off of the valve.

To remedy these difficulties, the rotary devices for dispensing liquid products are generally provided with cleaning means.

These cleaning means can be formed by a simple brush capable of being in frictional contact with the end of each valve during the rotational drive of the carousel, as illustrated in patent EP 2,651,574.

The cleaning is in this case a so-called "dry" cleaning.

However, such cleaning is not always effective.

A more effective solution is to practice a so-called "wet" cleaning.

This wet cleaning consists of washing the ducts and the valve spherical tips by means of brushes or mobile sponges, generally rotating, having a humidification system with a cleaning solution, which can be water-based, in the case of water-soluble paint or a solvent in particular based on acetone, in the case of solvent-based paint.

In this case, the cleaning enclosure is stationary and disposed on the path followed by the valves.

This cleaning enclosure is most often constantly open, which entails a risk of pollution of the atmosphere around the enclosure and / or of the contents 4 of the enclosure.

The wet cleaning solution is therefore not satisfactory in its current design.

An object of the invention is to provide a device for the storage and distribution of liquid products of the aforementioned type, the design of which allows so-called wet cleaning under improved conditions.

'a metering station and is positionable within said at least one row of valves.

According to one embodiment of the invention, the valve holder support is mounted to move back and forth and the valves, organized in at least one row, are arranged in one or more rectilinear rows on said valve holder support. .

7 According to one embodiment of the invention, the device comprises means for driving the movement of the valve holder support and a unit for controlling the means for driving the movement of the valve holder support.

5 According to one embodiment of the invention, the device comprises a sensor for detecting the position of the cleaning enclosure and the unit for controlling the means for driving the movement of the valve holder support is configured to prevent the moving the valve carrier into the close state of the valve carrier housing.

According to one embodiment of the invention, the device comprises an opening / closing control mechanism of a valve and the unit for controlling the means for driving the movement of the valve holder support is configured for, after each opening of a valve using the opening / closing control mechanism of a valve, control the movement of the valve holder support in the direction of the cleaning system for cleaning the valve which has just been opened.

A further subject of the invention is a method for cleaning container metering valves fitted to a device for storing and dispensing liquid products stored in said containers, characterized in that the device for storing and dispensing liquid products being of the aforementioned type, the method comprises a step of opening the member for closing the opening of the enclosure by moving the enclosure in the direction of bringing the valve holder support together.

The invention will be clearly understood on reading the following description 8 of exemplary embodiments, with reference to the accompanying drawings in which: FIG. 1 shows a front view of a device for the storage and distribution of liquid products. according to the invention in which the valves are arranged in a circumferential row; FIG. 2 represents a rear view of a device for the storage and distribution of liquid products in accordance with the invention; FIGS. 3 to 5 represent, in the form of partial detailed views of FIG. 1, the displacement of the enclosure of the device for the storage and distribution of liquid products of FIG. 1 for the passage from the closed position to the position opening of the closure member of the opening of said enclosure; FIGS. 6 to 8 represent, in the form of partial detailed views of FIG. 2, the movement of the member for closing the opening of the enclosure of the device for the storage and distribution of liquid products 20 of FIG. 2 for the passage from the closed position to the open position of the opening of said enclosure; and FIG. 9 shows a front view of a device for the storage and distribution of liquid products according to the invention in which the valves are arranged in a rectilinear row.

As mentioned above, the device 1, object of the invention, is more particularly intended to allow the storage and distribution of liquid products, such as base colors for paints, stored in containers 30 equipped with valves. 31 of dosage.

These containers 9 can take a number of shapes.

Examples are provided in patents EP 2,135,668, EP 2,651,574 and FR 2,983,089.

In practice, these containers 30 comprise at least one flexible bag 5 equipped with a metering valve 31.

This flexible pouch can be associated with an overpack or housed in a cell, acting as an overpack, of the storage and distribution device 1.

The bag is emptied by compressing the bag as described in the aforementioned documents using a pressurized fluid supply system fitted to the storage and distribution device 1.

The device 1 for storing and distributing liquid products 15 therefore comprises, for receiving the containers 30, a mobile valve support 2.

This 2 valve holder support can have a large number of shapes.

Regardless of the design of the 2 valve holder support, the metering valves 31 are organized on the 2 valve holder support in at least one row of valves.

Thus, in the example shown in FIG. 1, the valve holder support 2 takes the form of a wheel on which the valves 31 are arranged in at least one circumferential row, each valve being arranged on a spoke of the wheel.

In the example shown in FIG. 9, the valves 31 are arranged in at least one rectilinear row on the support 2 valve holders.

The device 1 comprises means 15 for driving the movement of the valve-holder support 2 and a unit 18 for controlling the means 15 for driving the movement of the valve-holder support 2.

In the example shown in FIG. 1, the support 2 valve holder is a rotary support.

The means 15 for driving the valve-holder support 2 in rotation may comprise a motor for driving the gears 5 in rotation engaging with the outer contour of the wheel constituting the valve-holder support 2 as described in patent FR 2.983. .089.

The control unit 18 takes the form of an electronic and / or computer system which comprises, for example, a microprocessor and a working memory.

According to a particular aspect, the control unit can be in the form of a programmable controller.

In other words, the functions and steps described can be implemented as a computer program or via hardware components (eg, programmable gate arrays).

In particular, the functions and steps performed by the control unit or its modules can be performed by instruction sets or computer modules implemented in a processor or controller or be performed by dedicated electronic components or FPGA type components. or ASIC.

It is also possible to combine computer parts and electronic parts.

When it is specified that the unit or means or modules of said unit 25 are configured to perform a given operation, this means that the unit comprises computer instructions and the corresponding execution means which make it possible to perform said operation and / or that the unit includes corresponding electronic components.

11 The control unit 18 is therefore configured to bring the metering valve 31 of each container 30 necessary for the production of the final product opposite a metering station 14 housed inside the wheel constituting the support 2 door -valves.

This metering station 14, which comprises a collecting container and means for weighing the contents of the collecting container, is well known to those skilled in the art and therefore will not be described in detail.

This metering station 14 is driven by an up and down movement to cover the valve 31 by a valve opening control mechanism 17 fitted to the metering station 14.

In fact, the dosing station 14 is generally equipped with a mechanism 17 for controlling the opening / closing of valves, also well known 15 and described, for example, in patent EP 1,975,486.

This valve opening / closing control mechanism can be formed by a cylindrical electric coil, such as a solenoid, capable of surrounding the valve and capable of inducing a magnetic field at the level of the valve equipped with a shutter charged by spring and sensitive to said magnetic field.

In the example shown in FIG. 9 where the valves are arranged in at least one rectilinear row, the means 15 for driving the movement of the valve holder support 2 are drive means 25 for reciprocating movement. of the 2 valve holder support.

These means 15 for driving the valve-holder support 2 in movement can, in this case, be formed by a double-acting cylinder arranged between the valve-holder support 2 and a stationary frame.

Again, the control unit of the double-acting cylinder may be in the form of an electronic and / or computer system as described above and may be of the same type as that described in connection with a support. 2 rotary valve holders.

Likewise, the metering station 14 which is generally located under the support 2 valve-holders can be of the same type as that described above for a rotary valve-holder support.

The device 1 for storing and distributing liquid products also comprises a system 3 for cleaning the valves 31.

The unit 18 for controlling the means 15 for driving the movement of the support 2 valve holders is configured for, after each opening of a valve 31 using the mechanism 17 for controlling the opening / closing of a valve. , control the movement of the valve holder support 2 in the direction of the cleaning system 3 for cleaning the valve 31 which has just been opened.

In the examples shown, the cleaning system 3 is arranged next to the dosing station 14 and can be positioned inside the row of valves in the case of a row of valves in circumferential arrangement or under the row of valves. in the case of a row of 20 rectilinear valves.

The valve cleaning system 3 is coupled to a support structure 4 formed here by part of the frame of the metering station 14.

Thus, in some installations, such as the one shown, the metering station 14 may be caused to move.

The cleaning system 3 follows this movement.

As a variant, the support structure 4 of the cleaning system 3 can be independent of the dosing station 14.

Regardless of the design of the support structure 4, the cleaning system 3 comprises an enclosure 5 and a cleaning member 6 housed 13 inside the enclosure 5 and means 7 for driving the member in movement. 6 for cleaning inside said enclosure 5.

The enclosure 5 is here in the form of an enclosure of generally parallelepiped shape.

The cleaning member 6 housed in the enclosure is here a rotary member 6 formed by a rotating radial bristle brush.

This rotary member 6 is mounted integral in rotation with a support pin 13 which projects from the enclosure and whose role will be described below.

The enclosure 5 is filled with a solution 32 for cleaning the valves.

This cleaning solution 32 can include volatile organic compounds.

Thus, the cleaning member 6 is at least partially immersed in said cleaning solution.

The enclosure 5 is provided with an opening 8 through which a valve 31 is adapted to project into the interior of the enclosure.

For this purpose, the device 1 comprises means 10 for driving the movement of the enclosure 5 between a separated position and a close position of the valve holder support 2 to allow the entry or exit of 20 l during the movement. one of the valves 31 of said enclosure.

These means 10 for driving the enclosure 5 in movement between a separated position and a close position of the valve holder support 2 comprise at least one actuator 100, such as a jack placed between the enclosure 5 and the structure 4. support for cleaning system 3.

In the example shown, the body of the actuator 100 is coupled to the support structure 4 of the cleaning system 3 and the rod of the actuator 100 is coupled to the enclosure 5.

Thus, the retraction of the cylinder rod causes the enclosure 5 to move apart from a valve 31 positioned opposite the enclosure, while the exit of the cylinder rod allows the enclosure to move closer together. a valve 31 of the valve holder support 2 up to a position in which the valve 31 extends partially inside the enclosure 5 as illustrated in FIG. 5.

The opening 8 of the enclosure through which a valve 31 is able to project inside the enclosure is a closable opening 8 equipped with a closure member 9.

The closure member 9 is movably mounted between a closed position and an open position of the opening 8 of the enclosure 5.

Preferably, the enclosure 5 is sealed in the closed state of the member 9 for closing the opening 8 of the enclosure 5.

Characteristically of the invention, the member 9 for closing the opening of the enclosure 5 is configured to pass from the closed position to the open position of the opening 8 of the enclosure 5 during the passage of the enclosure 5 from the separated position of the 2 valve holder support to the close position of the 2 valve holder support.

Said enclosure 5 acts as a pusher on the member 9 for closing the opening of the enclosure 5.

This closure member 9 is in the form of a simple flat plug provided with a gasket coming in the closed position to cover the opening 8 of the enclosure 5.

This member 9 for closing the opening 8 of the enclosure 5 is coupled to the support structure 4 by a link 11 comprising a spring loaded pivot link 110.

In the example shown, the link 11 comprises an arm 1101 equipped at one end of the member 9 for closing the opening 8 of the enclosure and connected at its end opposite to the support structure 4.

This arm 1101 30 incorporates a hinge 1100 forming the pivot link 110 of said link 15 11.

This 1100 hinge is a piano type hinge.

This hinge is, at its pivot axis, equipped with the spring 12.

This spring 12 is a helical hairpin spring wrapped around the connecting pin of the hinge leaves and resting by each of its ends on a hinge leaf, said hinge leaves being interconnected. by the hinge pin.

The spring 12 is thus configured to return the closing member 9 to the closed position.

The enclosure 5, for its part, exerts the function of a pusher and is configured to, in the driven state moving in the direction of an approach of the support 2 valve holder, exert a thrust on the member 9 of closure against the action of the spring 12 which tends to press the closure member 9 onto the opening 8 of the enclosure 5.

The thrust exerted by the enclosure 5 on the closing member 9 during the movement of the enclosure 5 towards the valve holder 2 causes, by breaking the arm at the level of the 110 pivot connection, the passage of 20 l 'member 9 for closing from the closed position to the open position.

In the close position of the enclosure 5 of the valve holder 2 support, a valve 31 of the valve holder 2 support partially protrudes inside the enclosure 5 in order to be cleaned there.

For this purpose, the device 1 comprises means 7 for driving the movement of the cleaning member 6.

These means 7 for driving the cleaning member 6 in movement are configured to drive the cleaning member 6 in movement at least in the open state of the member 9 for closing the opening 8 of the enclosure. 5.

These means 7 for driving the cleaning member 6 in movement are mounted on a frame comprising the enclosure 5.

The movement of the enclosure 5 therefore causes a movement of the means 7 for driving the movement of the member 6 for cleaning.

These means 5 7 for driving the movement of the cleaning member 6 therefore follow the movement of the enclosure 5.

These means 7 for driving the cleaning member 6 in movement comprise at least one actuator 72, such as a jack, configured to operate in a sequenced manner with the actuator 100 of the means 10 for driving the movement of the cleaning member. 'pregnant 5.

In particular, the actuator 72 of the means 7 for driving the cleaning member 6 in movement is configured to drive the cleaning member 6 in movement in a position close to the chamber 5 of the corresponding valve holder 2. to the output position of the rod of the cylinder constituting the actuator 100 from the means 10 for driving the displacement of the enclosure 5.

In the examples shown, the cleaning member 6 is a rotary member mounted on a support shaft 13 integrally in rotation with said shaft.

In particular, the cleaning member 6 takes the form of a brush with radial bristles, the support axis 13 forming the center of the brush around which the bristles are radiating.

This support axis 13 projects outside the enclosure 5 and is equipped, at its part outside the enclosure 5, with a pinion 73 coaxial with the support axis 13.

This pinion 73 is capable of coming into engagement by meshing with a rack 71 coupled to the rod of the constituent jack 17 of the actuator 72 of the means 7 for driving the rotational displacement of the member 6 for cleaning.

The body of the actuator constituting the actuator 72 is coupled to the enclosure 5 or 5 to a moving part integral with the enclosure 5.

Thus, the retraction and the exit of the rod of the constituent jack of the actuator 72 of the means 7 for driving the rotational displacement of the cleaning member 6 drive back and forth the rack 71 which itself drives in rotation the pinion 73, and consequently the member 6 for cleaning.

10 To complete the assembly, the device 1 comprises a sensor 16 for detecting the position of the cleaning chamber 5 and the unit 18 for controlling the means 15 for driving the displacement of the support 2 valve holder is configured to preventing the movement of the valve holder 2 in the close state of the enclosure 5 of the valve holder 2 holder.

This avoids the tearing of a valve which would protrude inside the enclosure 5.

The sensor 16 for detecting the position of the cleaning enclosure 5 20 can be a presence or proximity sensor.

The cleaning of a valve using such a device 1 therefore takes place as follows: A valve 31 is, by driving in movement of the support 2, valve holder positioned opposite the metering station 2, and open. by the valve opening / closing control mechanism 17 in order to discharge a part of the container 30 closed by the valve into a collecting container fitted to the metering station 14.

This metering station 14 equipped with the valve opening / closing control mechanism 17 is mounted movably up and down in order to come into the upper position, using the valve opening / closing control mechanism, a valve and allow it to open.

5 Once the valve has been closed and the dosing station 14 lowered, the valve holder support 2 is then again moved to bring the valve 31 which has just been opened opposite the chamber 5 of the cleaning system 3.

In this position of the valve 31, the cleaning chamber 5 is driven in movement by the cylinder 100 in the direction of an approach of the support 2 valve holder to a position in which the valve 31 protrudes from the side. 'inside the enclosure 5.

In this position close to the enclosure 5 of the valve holder support 2, the cleaning member 6 is driven in movement by actuation of the actuator 72 of the means 7 for driving the movement of the cleaning member 6.

Once the cleaning is complete, the enclosure 5 is moved away from the support 2 valve holders, and a new dosage can be carried out.

20 Thus, it is possible after each opening of a
