Description

The present invention relates to the field of painting, particularly for automobiles. The present invention relates more particularly to a cover and a system for stirring or preserving paint mixtures for the automobile.

Automotive body repair requires the application of paint in the final phase. When a part of the vehicle is to be repainted, the hue applied must be identical to the original color or the actual color at the time of repair.

Each repair does not necessarily involve repainting the entire vehicle. When the color of a vehicle has deteriorated in time by aging, it must be possible to restore the correct color in a well-defined area. An appropriate formulation, possibly corrected according to a coloristic measure or the painter's know-how, will be defined to repaint the vehicle.

On each vehicle, there is a reference corresponding to the color of the car manufacturer. This reference makes it possible to find on a data sheet, microfiche or sample pallet catalog a recomposition formula for the color from a set of mixed basic colors.

The base of the hundred thousand currently achievable formulas can be recomposed using 40 to 150 base shades of a manufacturer's paint line.

Generally, the realization of a formula is carried out using 3 to 10 basic colors, the average being 5 shades of base.

Base colors are a mixture of pigments, varnishes and binders, such as resins, solvents and additives. For a formulated base tint to be perfectly successful, a precise dosage, on the order of 0.05 g, but also a perfect homogenization of colored pigments in the binder. Therefore, it is necessary to proceed with the agitation of the basic colors before use to ensure excellent reproduction of their coloristic powers. Indeed, it is accepted that a set of well homogenized base shades allows a correct recomposition of the hue to achieve.

The normative evolution obliging the paint manufacturers to reduce the amount of solvents in the base colors led them to innovate on the chemical components of the paints and thus to modify the physicochemical structures of these. This had the effect of reducing the agitation time from 15 minutes to 5 minutes on the stirring protocol, or even to bring the stirring time to 0 min.

Today, some of these paints no longer require a stirring protocol, however, they need to be shaken before use, which can cause an emulsion and therefore difficulties in the assay. There are also cures of certain colors over time if they are not agitated.

Currently, there is a set of materials that allows stirring and dosing according to a process established by the paint manufacturers.

There are already special cabinets including a mechanical transmission system on which are arranged pots of basic colors with a stirrer / doser cover. A stirring blade is mechanically driven in a rotational movement in the paint bucket caused by the rotation of the pot and lid to achieve homogenization itself. The dosage is done through a lid which is equipped with a spout equipped with a progressive system of automatic opening and closing allowing the control of the pouring movements of a greater or lesser amount of paint. .

However, these systems depend on the viscosity of the hues contained in the pots. Indeed, according to the viscosity of the hues, the hues can be driven by the rotation of the pot. The stirring blade being rotated by the pot, its effect on homogenization can be inefficient.

The document US 3,041,052 teaches a container agitator cover comprising an agitator shaft, one end of which includes a blade and the other end comprises a coupling device with a drive system of the agitator shaft. The first blade is secured to the agitator shaft. The lid further comprises a second blade mounted free to rotate on the agitator shaft between the lid and the first blade. This cover has a complex blade system. In addition, it is necessary to use a drive system which must be coupled to the agitator shaft, which can be difficult to manage for several lids.

The document US 4,330,216 teaches a gravity-induced mixing device for a rotary container. The device comprises a mobile mixer adapted to be positioned in a rotary container and to transmit the rotational movement to the liquid contained in the container. A gravity mixing mechanism is associated with the container and with the mixer. This device also has a complex system by at least the gravity mixing mechanism. In addition, this device is rather suitable for bottle-type containers.

In the rest of the description, we will refer to the figures listed above.

The invention relates to a stirrer cover (5) intended to be fitted on a container (1).

This cover (5) comprises a hollow cylinder (60) perpendicularly crossing the lid at its center.

An agitator shaft (61) is telescopically mounted in the hollow cylinder (60).

A first end (62) of the axis (61) agitator is mounted free at least in translation in the cylinder (60) hollow. This first end (62) can also be rotatably mounted in the hollow cylinder (60).

The second end (63) of the axis (61) agitator is provided with at least one blade (6) stirring.

The hollow cylinder (60) may have an open end to allow the stirrer shaft (61) to slide and a closed end outside the container (1) when the lid (5) is fitted to the container (1). so that, for example, the axis (61) agitator does not come out of the hollow cylinder or to limit the stroke of the axis (61) agitator in the cylinder (60) hollow.

To adapt the lid (5) to the container (1), the second end (63) of the shaft (61) agitator provided with the blade or blades (6) is first introduced into the cylinder.

At the moment when the second end (63) reaches the bottom of the container, the axis (61) agitator is driven by sliding inside the hollow cylinder (60) until the lid (5) is adapted or fixed on the container (1). Thus, it is possible to adapt the lid (5) for all container sizes (1). The Figures 1 and 3 represent a configuration where a lid (5) for stirring adapted to a container of 0.5 L. figures 2 and 4 represent another configuration where the cover (5) of Figures 1 and 3 is suitable for a container of 1 L.

In addition, the blade or blades (6) are driven at least in rotation by its own weight around the axis (61) agitator. So when the container rotates with the cover, the blade or blades (6) remain positioned mainly vertically relative to the ground thanks to its own weight.

The blade can be fixed on the agitator shaft by at least one ring (64) surrounding the axis (61) agitator.

In the examples shown on the Figures 1 to 4 , the blade (6) is fixed to the axis (61) agitator by two rings (64) but the number of rings (64) can be greater or less than two. The axis (61) agitator may comprise two circular bulges between which are located the two rings (64). Thus the blade or blades (6) have freedom of movement relative to the axis (61) agitator limited by the two bulges. The bulge (66) located closest to the hollow cylinder (60) can serve as a stop for the hollow cylinder (60) to limit the sliding stroke of the agitator shaft (61) relative to the hollow cylinder (60).

The second end (63) may be of frustoconical shape and comprise a slot (65) along its longitudinal axis. The small base of the frustoconical shape is free and the large base of the frustoconical shape forms the circular bulge (66) farthest from the first end (62) of the shaking shaft (61) on which one of the rings (64) the blade or blades (6) abuts. This slot assembly and frustoconical shape allows the mounting of the blade or blades (6) on the shaft (61) agitator. During a blade assembly (6), the axis (61) agitator is introduced into each ring (64) one after the other. The inner diameter of each ring (64) is smaller than the diameter of the circular bulge (66) of the large base of the frusto-conical shape. Forcing the passage of the shaker shaft (61) into a ring (64), the slot (65) ) reduces the diameter of the circular bulge (66) to allow the passage of the rings (64). As soon as a ring (64) is passed, the diameter of the bulge (66) returns to its initial position by its elasticity. Thus, when the axis (61) agitator has been introduced into all the rings (64) of the blade or blades (6), the blade or blades will be linked to the axis (61) agitation while keeping a freedom of movement by rotation at the ring (s) (64) and optionally a freedom of movement by translation relative to the longitudinal axis of the axis (61) agitator.

Preferably, when the axis (61) agitator touches the bottom of the container (1), the blade or blades (6) do not touch the bottom of the container (1) leaving a space between the bottom of the container (1) and the blade or blades (6). This space can be defined by the height of the frustoconical shape.

In order to improve the entrainment by its weight of the blade (6), the end of the blade (6) opposite the end connected to the axis (61) agitator has a portion (67) heavy integral with the pale (6). This heavy portion (67) may be a cylindrical surface portion whose radius of curvature is substantially equal to the radius of curvature of the container (1). Thus, the weighing portion (67) is mounted such that the curvature of the heavy portion (67) is parallel to the curvature of the container (1) and in such a manner that there is a gap between the weighing portion (67) and the inner wall of the container (1).

The heavy portion (67) may take other forms such as, for example, a plate fixed perpendicularly to the blade (6).

The heavy portion (67) may be of the same material as the blade (6) or of a different material. If another material is used, it may be of a material of higher density than the material of the blade (6).

In order to improve the homogenization of the contents of the container (1), the blade (6) is perforated. The Figures 1 to 4 represent one day (68) of triangular shape. But, the shape can be different and take, for example, the form of grid or circular holes.

The blade (6) can take different forms. The Figures 1 to 4 represent a blade (6) of generally trapezoidal shape whose large base forms the end fixed to the agitator axis and the small base comprises the heavy portion (67).

The blade (6) may be metallic or any other suitable material allowing the blade (6) to remain mainly vertical thanks to its own weight.

The lid (5) can be adapted to seal the cylindrical container (s) (1). Closing the lid (5) on the container or containers (1) can be done by clipping, screwing or other means of fixing the lid on the container. In one configuration, the lid (5) is provided with clamping means on the lid body which are clipped to the interlocking crown of the container to be covered. The clamping means comprise two elastic fingers (51) automatically bearing against the annular surface of the crown when the body of the lid is positioned on the container by being applied, for example, on the bead (53) of existing crimping paint cans and other containers used especially in the automotive industry. This type of clamping makes it possible to fix the lid (5) on the container (1). It should be noted that the invention is not limited to this first embodiment alone, the attachment of the cover being obtainable by any clamping device or cam closure, bayonet, with screwing, or other known technique.

The outer diameter of the lid (5) is significantly greater than the container diameter (1), the lid (5) having an inner skirt (52) whose outer diameter corresponds to the inner diameter of the container (1).

According to one configuration, the lid (5) further comprises a pouring spout system (10) with a variable flow rate. In one configuration, the variable flow spout system includes an outlet port, a flattened closure member (101) for closing the port and means (102) for driving the translational closure member (101). in said opening plane. The drive means (102) include a pull rod connected by fastening means (103) to the closure element and comprising an end portion secured to a push means (104) driving said rod in the direction of the opening.

In one configuration, the flattened closure member (101) comprises a rigid body (105) whose surface in contact with the opening plane of the orifice is covered by a portion (106) of hydrophobic material and facilitating sliding. of the closure element (101) flattened in the plane opening. The rigid body (105) is made of a more rigid material than the hydrophobic material part. The fastening means (103) connecting the pull rod to the closure member (101) are integrally formed with the rigid body (105). The hydrophobic portion (106) is made of, for example, high density polyethylene (HDPE), or polytetrafluoroethylene (PTFE), or very high molecular weight polyethylene (PE-UHMW) or any other material having similar properties. For example, the hydrophobic portion (106) may be adhered to the rigid body (105). For example, the hydrophobic portion (106) can crimp or encase the rigid body (105). This closure element configuration makes it possible to improve the tightness of the spout when it is closed by the closure element.

In one configuration, the variable flow pourer spout system (10) is controlled by a slider returned to the closed position by resilient means and whose open position is defined by a handle rotatably mounted on the cover opposite the spout and solidarity moving with the slide by a linkage.

In one configuration, the lid (5) further comprises a handle (11) gripping for grasping the lid (5) alone or to grasp the lid (5) with the container attached to the lid (5). This handle handle (11) also facilitates the pouring of the paint contained in the container. It also makes it easy to handle the spout system (10).

The invention also relates to a system (0) for agitation or conservation of paint contained in at least one cylindrical container (1) on which is fitted a lid (5) according to the invention. A cylindrical container (1) may be a pot or bottle containing paint, one or more basic colors.

Agitation or preservation is similar to maintaining the original homogeneity of the color pigments rather than resuspending by stirring these pigments. The effect of this preservation will also have a reducing effect on the hardening during the period of use.

The system (4) comprises at least one series (2x1; 2x2) of rollers (2a1, 2b1, 2a2, 2b2) cylindrical regularly aligned on at least one support (31, 32). The cylindrical rollers (2a1, 2b1; 2a2, 2b2) have axes parallel to each other.

These cylindrical rollers (2a1, 2b1, 2a2, 2b2) are inclined with respect to a vertical axis (12) of an angle a. Without limitation, this angle (a) is between 20 ° and 60 °, preferably 45 °. The inclined position allows a better circulation of the paint in the containers when the containers rotate. It also improves the ergonomic conditions for handling containers.

At least one cylindrical roller (2a1, 2a2) on two adjacent cylindrical rollers (2a1, 2b1, 2a2, 2b2) is rotated about its axis (11) by a drive system (4).

The distance (d1, d2) between two adjacent cylindrical rollers (2a1, 2b1, 2a2, 2b2) is less than or equal to the diameter of a cylindrical container (1) so that the cylindrical surface of the container can rest on the cylindrical surface of two adjacent cylindrical rollers (2a1, 2b1, 2a2, 2b2).

So that the rollers (2a1, 2b1, 2a2, 2b2) cylindrical can transmit their rotation to the containers resting on them, the rollers (2a1, 2b1, 2a2, 2b2) cylindrical have a cylindrical surface covered with a gripping or non-slip material . The gripping material may be rubber or any other material to grip the surface cylindrical container of a cylindrical container so that the cylindrical rollers driven transmit their rotation to (x) container (s).

The rotational speed transmitted by the cylindrical rollers is constant regardless of the diameter of the cylindrical containers.

For example, the speed of rotation transmitted by the cylindrical rollers is of the order of 3 rpm at 15 rpm.

The diameter of the cylindrical rollers (2a1, 2b1, 2a2, 2b2) can be chosen according to the speed of rotation that is to be transmitted to the cylindrical containers. Thus, for the same speed of rotation of the cylindrical rollers, the larger the diameter of the cylindrical rollers, the greater the rotational speed of the cylindrical container or containers transmitted by the cylindrical rollers.

The lid (5) may have a cylindrical peripheral surface whose diameter is greater than the diameter of the cylindrical container (1) on which the lid (1) is adapted. In order for the rollers to effectively drive the container or receptacles, the cylindrical rollers (2a1, 2b1, 2a2, 2b2) comprise two cylindrical portions (200, 201). A first cylindrical portion (200) for receiving at least the peripheral surface of the lid (5) has a diameter smaller than the diameter of the second cylindrical portion (201) forming, for example, the base of the roller and for receiving at least one part of the cylindrical surface of the container (1) on which the lid (5) is fitted. The difference in diameter of the two cylindrical parts of a cylindrical roller is, for example, equal to the difference between the diameter of the peripheral surface of the lid (5) and the diameter of the cylindrical surface of the container (1). The first portion (200) of a roller can be connected to the second portion (201) of the roller by a frustoconical portion (202). The base of the frustoconical portion (202) has a surface that may be equal to the cross sectional area of the second portion (201). The top of the frusto-conical portion (202) has a surface that may be equal to the cross-sectional area of the first portion (200). In order to adapt to several types of container / lid assemblies, the surface of the rollers can be removable to change the dimensions of the first cylindrical portion and the second cylindrical portion of the roller.

According to a first configuration ( figure 5 ), the drive system (4) comprises a driving pulley (6) driving a belt (7). The drive system (4) further comprises a plurality of pulleys (3a1, 3a2) integral with the cylindrical rollers driven by the belt (7). Considering the driving direction (8) of the belt (7), the belt (7) is alternately arranged on a right side of a first pulley (3a1) of a cylindrical roller then a left side of a second pulley (3a2) of the adjacent cylindrical roller. Each of the pulleys (3a1, 3b1) associated with a roller (2a1, 2b1) cylindrical is followed and / or preceded by a pulley (3b2) of cylindrical roller leaving crazy in rotation its roller (2b1) associated cylindrical. Thus, when a container (1) rests on two adjacent cylindrical rollers, the roller (2a1) cylindrical driven by its associated pulley (3a1) rotates the container (1) cylindrical about its axis. The cylindrical roller (2b1) left idle in rotation by its associated pulley (3b2) then serves as a support for the container (1) which itself transmits the rotation to this cylindrical roller left crazy in rotation.

According to a second configuration ( figure 6 ) the drive system (4) comprises a driving pulley (6) driving a belt (7). The drive system (4) further comprises a plurality of pulleys (3a1) integral with the cylindrical rollers driven by the belt (7) and a plurality of intermediate pulleys (4a1) disposed between two pulleys (3a1) integral with the cylindrical rollers. Considering the driving direction (8) of the belt (7), the belt (7) is alternately arranged on a right side of a pulley of a roller roller and then on a left side of a pulley (4a1) adjacent intermediate. Each of the cylinder pulleys (3a1) is associated with a cylindrical roller and drives its associated cylindrical roller. Intermediate pulleys (4a1) make it possible to tension the belt (7) and pressing the belt against the cylindrical roller pulleys (3a1) so that the transmission of the movement by the belt (7) can be fully supplied to the cylindrical roller pulleys (3a1).

Other configurations are possible so that the cylindrical containers (1) can rotate about their axis.

The belt (7) is a circular section belt. But other forms of belts are conceivable, such as a synchronous belt.

The driving pulley (6) is driven by a motor (9). In one configuration, the driving pulley (6) has a vertical axis of rotation while the cylindrical rollers (2a1, 2b1, 2a2, 2b2) have an axis inclined relative to the vertical. Thus, a return pulley (10) makes it possible to transmit the movement transmitted by the belt (7) by the driving pulley (6) to the pulleys (3a1, 3b1) of a cylindrical roller.

In one configuration, the motor (9) is an electric motor transmitting a variable speed of rotation to the driving pulley (6).

In one configuration, a plurality of supports (31, 32) each supporting a series (2x1, 2x2) of cylinders are disposed one above the other. The space between each support allowing at least the passage of a container so that the container (1) can be deposited on two adjacent cylindrical rollers. The supports (31, 32) are mounted as removable shelves held by common uprights (13). A shaft (14) transmits the rotation of the motor to the drive pulleys (6) of each support.

In one configuration, the distance (d1) between two adjacent rollers (2a1, 2b1) of a first series (2x1) of cylindrical rollers is different from the distance (d2) between two adjacent cylindrical rollers (2a2, 2b2) of a second series (2x2) of cylindrical rollers. The distance d1 between two rollers (2a1, 2b1) adjacent rolls of a first series (2x1) of cylindrical rollers may be, for example, smaller than the distance d2 between two adjacent cylindrical rollers (2a2, 2b2) of a second series (2x2) of cylindrical rollers. Thus, cylindrical containers (1) of small diameters may be arranged on the first series (2x1) of cylindrical rollers while containers (1) of larger diameters may be arranged on the second (2x2) series of cylindrical rollers. The stirring or storage system may include a plurality of supports supporting a plurality of cylindrical roller sets.
