Description
SYSTEME DE DOSAGE POUR PRODUITS GRANULÉS
OU PULVÉRULENTS
La présente invention a pour objet un système de dosage pour produits granulés ou pulvérulents.DOSING SYSTEM FOR GRANULATED PRODUCTS
OR POWDERS
The subject of the present invention is a dosing system for granular or pulverulent products.
Il peut s'appliquer à toutes les installations nécessitant un dosage précis de plusieurs composants à mélanger se présentant sous forme de poudres et/ou de granulés, mais il est tout particulièrement destiné à l'alimentation des machines d'injection ou d'extrusion de matière plastique. It can be applied to all installations requiring a precise dosage of several components to be mixed in the form of powders and / or granules, but it is particularly intended for the supply of injection or extrusion machines of plastic material.
Les formulations employées dans ce domaine sont obtenues par le mélange d'un ou de plusieurs types de matériau de base avec une série d'additifs utilisés en petites quantités, chaque composant étant en général pesé séparément, dans des trémies distinctes adaptées à un type de produit, puis acheminé dans un mélangeur. Les installations ainsi réalisées sont souvent très encombrantes; leur mise au point et leur maintenance sont rendues difficiles en raison d'équipements disparates provenant en général de plusieurs constructeurs. Les investissements et couts de fonctionnement de tels ensembles sont en conséquence élevés. The formulations used in this field are obtained by mixing one or more types of base material with a series of additives used in small quantities, each component being generally weighed separately, in separate hoppers adapted to a type of product, then routed through a blender. The installations thus produced are often very bulky; their development and maintenance are made difficult due to disparate equipment generally coming from several manufacturers. The investments and operating costs of such assemblies are consequently high.
Le dispositif selon la présente invention a pour objectif de remédier à ces inconvénients. I1 permet en effet de réaliser un ensemble de dosage compact et homogène, d'un coût très compétitif, d'une grande fiabilité et facilement adaptable à diverses configurations. The device according to the present invention aims to remedy these drawbacks. I1 makes it possible to produce a compact and homogeneous dosing unit, at a very competitive cost, with high reliability and easily adaptable to various configurations.
Il est constitué d'une double trémie de pesage montée sur un seul jeu de pesons et constituée d'une enceinte de volume important pour le ou les produits constituant la plus grande partie du mélange final, et d'une enceinte de volume réduit pour les produits intervenant en faible quantité, ces deux enceintes étant, après les opérations de pesage effectuées séquentiellement, vidangées simultanément dans une trémie de réception ou dans un mélangeur intégré. It consists of a double weighing hopper mounted on a single set of load cells and consisting of a large volume enclosure for the product (s) constituting most of the final mixture, and a reduced volume enclosure for the products intervening in small quantity, these two enclosures being, after the weighing operations carried out sequentially, emptied simultaneously into a receiving hopper or into an integrated mixer.
Le dessin schématique annexé, donné à titre d'exemple explicatif, mais nullement limitatif d'une des formes de réalisation de l'objet de l'invention, représente dans son ensemble un système de dosage, avec l'unité de pesage et de mélange vue en coupe axiale verticale. The attached schematic drawing, given by way of explanatory example, but in no way limiting on one of the embodiments of the subject of the invention, as a whole represents a dosing system, with the weighing and mixing unit vertical axial section view.
Le dispositif est constitué d'une trémie de pesage 1 constituée de deux enceintes solidaires : une trémie principale 2 recevant les produits en grande quantité ("macro-composants"), et une trémie additionnelle 3 destinée aux produits en faible quantité ("micro-composants") tels qu'additifs divers ou colorants, l'ensemble reposant sur un bâti support 4 par l'intermédiaire de capteurs de pesée 5 sensibles à la pression. The device consists of a weighing hopper 1 made up of two integral enclosures: a main hopper 2 receiving the products in large quantity ("macro-components"), and an additional hopper 3 intended for the products in small quantity ("micro- components ") such as various additives or dyes, the assembly resting on a support frame 4 by means of weighing sensors 5 sensitive to pressure.
La trémie principale 2 peut être chargée par tous les moyens utilisés habituellement, tels que convoyeurs ou vis d'Archimède, mais elle sera de préférence à alimentation pneumatique, soit par soufflage (produits poussés par de l'air sous pression), soit par aspiration assurée par une pompe à vide 6 au travers d'un filtre primaire 7 situé à la partie supérieure de la trémie, celle-ci constituant alors une enceinte étanche sous vide. L'ensemble peut être complété par un filtre principal 8 disposé sur le conduit 9 de raccordement de la pompe à l'unité de pesage. The main hopper 2 can be loaded by any means usually used, such as conveyors or Archimedes' screws, but it will preferably be pneumatically supplied, either by blowing (products pushed by pressurized air) or by suction. provided by a vacuum pump 6 through a primary filter 7 located at the top of the hopper, the latter then constituting a vacuum-tight enclosure. The assembly can be completed by a main filter 8 disposed on the conduit 9 for connecting the pump to the weighing unit.
L' alimentation pneumatique permet de raccorder directement la trémie principale 2 aux trémies de stockage par une ou plusieurs tubulures d'alimentation 10 ouvertes séquentiellement grâce à un jeu de vannes 11. The pneumatic supply makes it possible to directly connect the main hopper 2 to the storage hoppers by one or more supply pipes 10 opened sequentially by means of a set of valves 11.
Ces tubulures, ainsi que le conduit d'aspiration 9 seront désolidarisés de la trémie de pesage au moyens de soufflets 12, 12' ou de portions tubulaires souples.These pipes, as well as the suction duct 9 will be separated from the weighing hopper by means of bellows 12, 12 ′ or flexible tubular portions.
La trémie additionnelle 3 sera avantageusement constituée d'une double enveloppe entourant la partie inférieure de la trémie principale 2 (cf figure 1), mais pourra également être formée d'une paroi de séparation créant un réceptacle distinct de celle-ci, ou encore d'un élément externe rendu solidaire par soudage, boulonnage ou tout autre moyen. La trémie additionnelle pourra être divisée en plusieurs compartiments recevant chacun un "micro-composant". The additional hopper 3 will advantageously consist of a double envelope surrounding the lower part of the main hopper 2 (see FIG. 1), but may also be formed of a partition wall creating a receptacle separate from it, or even d '' an external element made integral by welding, bolting or any other means. The additional hopper can be divided into several compartments, each receiving a "micro-component".
Les produits à doser en faible quantité seront de préférence acheminés par vis d'Archimède 13, ou éventuellement par convoyeurs à bande 14, couloir vibrant ou tout autre système, vers la trémie additionnelle à partir d'enceintes de stockage 15 de diverses capacité montées sur le bâti support 4 de l'unité de pesage. The products to be dosed in small quantities will preferably be conveyed by Archimedes' screw 13, or possibly by belt conveyors 14, vibrating corridor or any other system, to the additional hopper from storage chambers 15 of various capacities mounted on the support frame 4 of the weighing unit.
La trémie principale 2 et la trémie additionnelle 3 sont fermées par un obturateur de vidange 16 unique actionné par vérin, ou par plusieurs obturateurs à fonctionnement simultané, de manière à vider en même temps tous les produits pesés dans une trémie de réception 17, disposée au-dessous des trémies de pesage, et qui pourra avantageusement être intégrée à l'unité de dosage et contenir le mélangeur 18, de manière à former ainsi un ensemble monobloc particulièrement compact. The main hopper 2 and the additional hopper 3 are closed by a single emptying shutter 16 actuated by jack, or by several shutters operating simultaneously, so as to empty all the weighed products in a receiving hopper 17, disposed at the same time. below weighing hoppers, which can advantageously be integrated into the metering unit and contain the mixer 18, so as to thus form a particularly compact monobloc assembly.
Les composants du mélange final sont pesés l'un après l'autre, séquentiellement, à l'aide d'un module électronique 19 de pilotage raccordé aux capteurs de pesée 5 et programmé pour déclencher successivement l'ouverture de chaque vanne d'alimentation 11, puis sa fermeture dès que le poids nécessaire du produit correspondant est atteint, ainsi que la mise en route et l'arrêt, dans les mêmes conditions, des vis d'Archimède 13 ou convoyeurs 14 des d'enceintes de stockage 15 de la trémie additionnelle. The components of the final mixture are weighed one after the other, sequentially, using an electronic control module 19 connected to the weighing sensors 5 and programmed to successively trigger the opening of each supply valve 11 , then closing it as soon as the necessary weight of the corresponding product is reached, as well as starting and stopping, under the same conditions, the Archimedes screws 13 or conveyors 14 of the storage chambers 15 of the hopper additional.
Le nombre de produits à mélanger peut être quelconque. Le nombre de vannes d'alimentation 11 pourra par exemple être compris entre un et six, et celui des enceintes de stockage de "micro-composants", entre un et douze, la capacité de ces enceintes pouvant varier, à titre indicatif, de 5 à 50 litres. The number of products to be mixed can be any. The number of supply valves 11 may for example be between one and six, and that of the "micro-component" storage enclosures, between one and twelve, the capacity of these enclosures being able to vary, by way of indication, from 5 at 50 liters.
Après pesage et mélange, le produit final obtenu est dirigé par un conduit d'évacuation 20 vers une aire de stockage ou directement vers les machines utilisatrices. After weighing and mixing, the final product obtained is directed through an evacuation pipe 20 to a storage area or directly to the user machines.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
