Abstract

The mixer consists of a drive (20) with an external tube (10), feeders (14, 16) for the products to be mixed, and an inner mixing spiral (18). The tube has an open outlet end (12) and contains a lengthwise elongated element (22) with closed ends (22a, 22b) inside the spiral. The elongated element is shorter than the spiral, has a diameter of between 50 and 90 per cent of the of the spiral. It has a circular or polygonal cross-section; its closed ends are conical or give in shape, and it is supported by a perforated plate (24) round the open end of the tube. The dimensions of the elongated element depend on the types of products to be mixed and their viscosity, being of smaller diameter for products likely to form lumps. A variant of the design has a second tube of smaller diameter to deliver a second product into the main tube from a hopper.

Description

La présente invention concerne une caisse de transport de tout type de matériel. La présente invention concerne plus particulièrement une caisse en matériaux légers pour transporter du matériel.The present invention relates to a transport case of any type of equipment. The present invention relates more particularly to a box lightweight materials for transporting equipment.

Il est connu par le brevet n° FR 2638073, une caisse navette obtenue à partir de panneaux plans, montés pour former la caisse par l'intermédiaire d'éléments de structure, tels que des cornières. Cette caisse comprend également des moyens de fermeture et des moyens de préhension pour son transport. Les panneaux sont fixés sur les cornières, par collage, par encastrement ou par rivetage. Pour améliorer la résistance de la caisse lorsqu'elle transporte des objets lourds, ce document propose de rigidifier les panneaux en les formant d'au moins une plaque en matériau à structure alvéolée ou cannelée, les alvéoles ou les cannelures étant orientées longitudinalement par rapport au plan constitué par le panneau auxquelles elles appartiennent. Pour rigidifier au maximum les panneaux, une deuxième plaque est positionnée sur la première, les cannelures de cette deuxième plaque étant orientées perpendiculairement aux cannelures de la première plaque. Ces plaques sont réalisées en carton ondulé ou en polypropylène à structure interne.It is known from patent No. FR 2638073, a shuttle box obtained at from flat panels, mounted to form the body through structural elements, such as angles. This case includes also closing means and gripping means for its transport. The panels are fixed to the angles, by gluing, by embedding or riveting. To improve the resistance of the body when transporting heavy objects, this document proposes to stiffen the panels by forming them from at least one plate of structure material dimpled or grooved, the dimples or grooves being oriented longitudinally with respect to the plane formed by the panel to which they belong. To make the panels as rigid as possible, a second plate is positioned on the first, the grooves of this second plate being oriented perpendicular to the grooves of the first plate. These sheets are made of corrugated cardboard or polypropylene with structure internal.

L'inconvénient principal de la caisse exposée dans ce document est que les panneaux, du fait de leur structure alvéolaire longitudinale, ont une résistance mécanique faible et ne peuvent pas supporter de grosses charges sans se briser. La solution présentée dans ce document est de disposer sur la première plaque une deuxième plaque du même type, la deuxième plaque disposant de cannelures orientées perpendiculairement aux cannelures de la première plaque. Cette solution n'est pas satisfaisante en ce qu'elle a pour effet d'augmenter les coûts de fabrication et également la masse de la caisse. The main disadvantage of the body exposed in this document is that the panels, due to their longitudinal honeycomb structure, have a low mechanical strength and cannot withstand heavy loads without breaking. The solution presented in this document is to have on the first plate a second plate of the same type, the second plate having grooves oriented perpendicular to the grooves of the first plate. This solution is not satisfactory in that it has the effect to increase manufacturing costs and also the mass of the body.

Il est également connu par le document n° FR 2754242, une caisse destinée aux transports d'objets, en particulier d'objets fragiles. Cette caisse est réalisée au moyen de panneaux assemblés par des cornières à double emboítement. Ces panneaux sont emboítés et collés dans les cornières. Chaque panneau est réalisé dans une résine synthétique telle que du polycarbonate et comprend une structure alvéolaire prise entre deux feuilles parallèles formant les faces du panneau. La structure alvéolaire est constituée de canaux parallèles longitudinaux à section rectangulaire ou carrée.It is also known from document No. FR 2754242, a box intended for the transport of objects, in particular fragile objects. This case is realized by means of panels assembled by double angles nesting. These panels are fitted and glued in the angles. Each panel is made of a synthetic resin such as polycarbonate and includes a honeycomb structure between two sheets parallel forming the faces of the panel. The honeycomb structure is made up of parallel longitudinal channels of rectangular or square section.

Les panneaux comprennent des alvéoles disposées longitudinalement, ce qui, comme écrit plus haut, leur confère une résistance mécanique faible. De plus, un autre inconvénient réside dans le fait que les panneaux sont collés dans les cornières. En effet, la structure de panneau selon ce document offre peu de résistance à la compression et se prête donc mal à l'utilisation de rivets ou de vis pour fixer les panneaux dans les cornières. Le collage permet donc d'éviter que les panneaux se déchirent lorsqu'ils supportent une charge importante, mais il ne constitue pas un moyen de fixation très performant.The panels include cells arranged longitudinally, which, as written above, gives them low mechanical strength. Of plus, another disadvantage is that the panels are glued in the angles. Indeed, the panel structure according to this document offers little resistance to compression and therefore does not lend itself well to the use of rivets or screws to fix the panels in the angles. Bonding therefore allows to prevent the panels from tearing when they support a load important, but it does not constitute a very effective fixing means.

La présente invention a donc pour objet de pallier les inconvénients de l'art antérieur en proposant une caisse légère pour le transport de matériel et dont les panneaux sont très résistants mécaniquement, et peuvent supporter tous types de moyens de fixation.The object of the present invention is therefore to overcome the drawbacks of the prior art by offering a light box for transporting equipment and whose panels are very mechanically resistant, and can withstand all types of fastening means.

Ce but est atteint par une caisse selon la revendication 1.This object is achieved by a box according to claim 1.

Des développements supplémentaires de l'invention sont décrits dans les revendications 2 à 9.Additional developments of the invention are described in claims 2 to 9.

  • la figure 1 représente une vue en élévation de la caisse selon l'invention,
  • la figure 2 représente, en vue de dessus, une portion de panneau selon l'invention,

The invention, with its characteristics and advantages, will emerge more clearly on reading the description made with reference to the appended drawings in which:

  • Figure 5 shows, in cross section, a socket angle.

La caisse selon l'invention va à présent être décrite en liaison avec les figures 1 à 5.The box according to the invention will now be described in conjunction with the Figures 1 to 5.

La caisse (1) représentée en figure 1 est par exemple parallélépipédique. Elle dispose, en règle général, d'un aménagement intérieur (non représenté) réalisé à partir de mousse et ayant une configuration spécifique en fonction du matériel à transporter dans la caisse (1). La caisse (1) est constituée de manière connue de plusieurs panneaux formant ses faces. Elle est divisée suivant un plan de joint transversal, formant une partie inférieure (10) et une partie supérieure. La partie supérieure constitue son couvercle (11) et vient se positionner sur la partie inférieure pour fermer la caisse. Lorsqu'elle est fermée, la caisse (1) est constituée de quatre panneaux (12) formant ses faces latérales, d'un panneau inférieur (13) formant son fond et d'un panneau supérieur (14) formant sa face supérieure et faisant partie de son couvercle (11). Les panneaux (12) latéraux sont divisés en deux parties suivant le plan de jonction de la partie inférieure (10) et du couvercle (11). Le couvercle (11) est mobile en rotation autour de charnières. Une fois le couvercle (11) rabattu sur la caisse (1), il peut être maintenu dans cette position par l'intermédiaire de moyens (15) de fermeture tels que, par exemple, des fermetures à papillon.The box (1) shown in Figure 1 is for example cuboid. It generally has an interior layout (not shown) made from foam and having a configuration specific according to the material to be transported in the box (1). The case (1) consists in a known manner of several panels forming its faces. It is divided along a transverse joint plane, forming a part lower (10) and an upper part. The upper part is its cover (11) and comes to position on the lower part to close the checkout. When closed, the box (1) consists of four panels (12) forming its lateral faces, of a lower panel (13) forming its bottom and an upper panel (14) forming its upper face and forming part of its cover (11). The side panels (12) are divided into two parts along the junction plane of the lower part (10) and the cover (11). The cover (11) is movable in rotation around hinges. Once the cover (11) folded over the body (1), it can be kept in this position by means of closing means (15) such as, for example, butterfly closures.

Les panneaux (12, 13, 14) sont assemblés pour former la caisse (1) par l'intermédiaire d'éléments de structure tels que des profilés. Certains profilés sont constitués de cornières doubles (16) formant les arêtes de la caisse (1). Ces cornières doubles (16), selon une variante représentée en figure 4, sont formées de deux ailes supérieures (160, 161) jointes et formant entre elles un angle droit et de deux ailes inférieures (162, 163) jointes, parallèles aux ailes supérieures (160, 161) et formant donc également entre elles un angle droit. Les deux paires d'ailes (160, 161, 162, 163) sont jointes par une portion (164) s'étendant le long de la bissectrice de l'angle formé par les deux ailes supérieures (160, 161). Les ailes supérieures (160, 161) sont espacées des ailes inférieures (162, 163) d'une distance correspondant sensiblement à l'épaisseur, définie par e, d'un panneau (12, 13, 14).The panels (12, 13, 14) are assembled to form the body (1) by through structural elements such as profiles. Some profiles consist of double angles (16) forming the edges of the body (1). These double angles (16), according to a variant shown in Figure 4, are formed of two upper wings (160, 161) joined and forming between them a right angle and two lower wings (162, 163) joined, parallel to the wings upper (160, 161) and therefore also forming between them a right angle. The two pairs of wings (160, 161, 162, 163) are joined by a portion (164) extending along the bisector of the angle formed by the two wings superior (160, 161). The upper wings (160, 161) are spaced apart from the lower wings (162, 163) of a distance corresponding substantially to the thickness, defined by e, of a panel (12, 13, 14).

La caisse (1) comprend également des profilés d'emboítement (17) représentées en figure 5 et constitués de deux ailes (170, 171) parallèles espacées de l'épaisseur e d'un panneau (12, 13, 14) et séparés par une portion (172) convexe ou concave. Ces profilés (17) prennent entre leurs ailes (170, 171), les extrémités supérieures des parties de panneaux (12) latéraux de la partie inférieure (10) et les extrémités inférieures des parties de panneaux (12) latéraux du couvercle (11). Par exemple, la partie convexe d'un profilé d'emboítement (17) situé sur la partie inférieure (10) de la caisse (1) collabore avec la partie concave d'un profilé d'emboítement (17) de la partie supérieure (11) de manière à bien refermer la caisse (1) et à lui conférer une certaine étanchéité.The body (1) also includes interlocking profiles (17) shown in Figure 5 and consisting of two parallel wings (170, 171) spaced apart from the thickness e of a panel (12, 13, 14) and separated by a portion (172) convex or concave. These profiles (17) take between their wings (170, 171), the upper ends of the side panel parts (12) of the lower part (10) and the lower ends of the panel parts (12) sides of the cover (11). For example, the convex part of a profile socket (17) located on the lower part (10) of the body (1) collaborates with the concave part of a socket profile (17) of the upper part (11) so as to close the box well (1) and to give it a certain seal.

La caisse (1) comprend également à chacun de ses sommets un coin (18) de renfort et de protection de la caisse (1) contre les chocs. Ces coins (18) peuvent être, par exemple, plats ou à boule, comme représenté en figure 1. La caisse (1) comprend également une poignée (19) encastrée pour pouvoir être facilement saisie. La caisse (1), pour être déplacée, pourra disposer également de roulettes (non représentées).The box (1) also includes a corner at each of its tops (18) for reinforcing and protecting the body (1) against shocks. These corners (18) can be, for example, flat or ball, as shown in Figure 1. The body (1) also includes a handle (19) recessed so that it can be easily captured. The box (1), to be moved, may also have casters (not shown).

Les panneaux (12, 13, 14) selon l'invention sont constitués d'une structure en nids d'abeille (200) et prise entre deux feuilles (201, 202) parallèles. Les nids d'abeille (200) représentés en figure 2 sont positionnés transversalement par rapport au plan formé par le panneau (12, 13, 14) auquel ils appartiennent. Les nids d'abeille (200) sont, par exemple, à section transversale hexagonale de 8 mm de côté et sont en polypropylène extrudé. Les deux feuilles (201, 202) enveloppant chaque panneau (12, 13, 14) sont dans un matériau spécifique tel que du polypropylène ou du polyester Le matériau constituant les feuilles (201, 202) est différent suivant la position occupée par le panneau (12, 13, 14) sur la caisse (1). Les panneaux (12) latéraux de la caisse (1) disposent préférentiellement de feuilles (201, 202) en polypropylène et les panneaux (13, 14) inférieur et/ou supérieur de la caisse sont dans un matériau différent, tel que le polyester. Le polyester est un matériau plus résistant en flexion, c'est pourquoi il est utilisé pour le panneau (14) supérieur de la caisse (1) et/ou pour le panneau (13) inférieur la caisse (1). En effet ces deux panneaux (13, 14) sont les panneaux susceptibles d'être les plus soumis à la charge du matériel disposé dans la caisse (1). Les panneaux à feuille en polyester sont le plus souvent utilisés lorsque des roulettes sont fixées sous la caisse (1). En effet, lorsque la caisse (1) est sur roulettes, le panneau (13) inférieur supporte en permanence toute la charge du matériel transporté dans la caisse (1).The panels (12, 13, 14) according to the invention consist of a honeycomb structure (200) and taken between two sheets (201, 202) parallel. The honeycombs (200) represented in FIG. 2 are positioned transversely to the plane formed by the panel (12, 13, 14) to which they belong. The honeycombs (200) are, for example, cross-section 8 mm hexagonal cross section and are made of extruded polypropylene. The two sheets (201, 202) enveloping each panel (12, 13, 14) are in a specific material such as polypropylene or polyester Le material constituting the sheets (201, 202) is different depending on the position occupied by the panel (12, 13, 14) on the body (1). Panels (12) sides of the box (1) preferably have sheets (201, 202) in polypropylene and the lower and / or upper panels (13, 14) of the body are in a different material, such as polyester. Polyester is a more bending resistant material, this is why it is used for the panel (14) upper body (1) and / or for the panel (13) lower body (1). Indeed these two panels (13, 14) are the panels likely to be the no longer subject to the load of the material placed in the box (1). The signs to polyester sheet are most often used when casters are fixed under the body (1). When the body (1) is on wheels, the lower panel (13) permanently supports all the material load transported in the box (1).

La structure des panneaux (12, 13, 14) leur permet d'être fixés sur les cornières (16, 17) par rivetage, comme représenté figure 1. Les rivets (20) traversent une aile inférieure (162, 163) et l'aile supérieure (160, 161) qui lui est parallèle ainsi que le panneau (12, 13, 14) et sa structure en nid d'abeille (200). Les panneaux (12, 13, 14) sont ainsi parfaitement fixés sur les cornières (16, 17).The structure of the panels (12, 13, 14) allows them to be fixed on the angles (16, 17) by riveting, as shown in Figure 1.
