Abstract
Description
La présente invention concerne un dispositif pour vider des récipients contenant des produits thermofusibles tels -que ceux couramment utilisés pour le collage, l'étanchéité ou encore l'isolation. The present invention relates to a device for emptying containers containing hot-melt products such as those commonly used for bonding, sealing or even insulation.
Ces produits peuvent se présenter sous forme de granulés; mais certaines qualités sont obligatoirement conditionnées sous forme de masses restreintes, emballée individuellement dans des récipients en matériaux souvent coûteux. De ce fait, il se pose d'énormes problèmes tant aux fabricants pour l'emballage, qu'aux utilisateurs lors du déballage. These products can be in the form of granules; but certain qualities are necessarily packaged in the form of restricted masses, individually wrapped in containers made of often expensive materials. As a result, enormous problems arise both for manufacturers for packaging and for users during unpacking.
Depuis quelques temps, certains fabricants de produits thermofusibles tels que ceux indiqués plus haut, livrent déjà ceux-ci dans des fûts de grande capacité. Pour vider de tels fûtes, des sociétés, notamment américaines, ont réalisé et commercialisent un matériel dérivé de celui utilisé dans la dépose de mastic à froid. Un tel matériel est en fait peu adapté pour de tels produits thermofusibles. For some time, some manufacturers of hot-melt products such as those indicated above, already deliver these in large capacity drums. To empty such barrels, companies, in particular American ones, have produced and market material derived from that used in the cold mastic removal. Such material is in fact not very suitable for such hot-melt products.
Les pompes utilisées dans ce type de matériel sont soit pneumatiques soit à engrenage à vitesse variable : avec des pompes pneumatiques il est pratiquement impossible d'assurer un débit régulier ; quant aux pompes à engrenage elles ne permettent pas d'homogénéiser le produit ni d'assurer, à faible vitesse, une régularité de dépôt nécessaire. The pumps used in this type of equipment are either pneumatic or variable speed gear: with pneumatic pumps it is practically impossible to ensure a regular flow; as for the gear pumps, they do not make it possible to homogenize the product nor to ensure, at low speed, a regularity of deposition necessary.
Aussi, un des buts de la présente invention est-il de fournir un dispositif pour vider des récipients contenant des produits thermofusibles permettant leur homogénéisation ainsi que leur distribution avec une tres grande précision de débit et de température. Also, one of the aims of the present invention is to provide a device for emptying containers containing hot-melt products allowing their homogenization as well as their distribution with very high accuracy of flow and temperature.
Un objet de l'invention est un dispositif de ce type qui fonctionne automatiquement. An object of the invention is a device of this type which operates automatically.
Ce but et cet objet ainsi que d'autres qui apparaitront par la suite, sont atteints par un dispositif pour vider des récipients contenant des produits thermofusibles qui, selon la présente invention, comporte des moyens de pompage situés sensiblement au sommet d'une tête constituée par deux plateaux, un plateau supérieur et un plateau inférieur perforé, délimitant entre eux une cavité intérieure dans laquelle débouche une conduite d'aspiration reliée aux moyens de pompage. Ces deux plateaux comprennent des moyens de chauffage et de régulation.Ce dispositif comporte également une conduite de refoulement reliée aux moyens de pompage pour évacuer les produits et une conduite située dans la tête, reliant cette conduite de refoulement a la cavité intérieure, et sur laquelle sont situés des moyens de commande et de contrle de la pression des produits dans la conduite de refoulement. This object and this object, as well as others which will appear subsequently, are achieved by a device for emptying containers containing hot-melt products which, according to the present invention, includes pumping means located substantially at the top of a head made up by two plates, an upper plate and a perforated lower plate, delimiting between them an interior cavity into which opens a suction pipe connected to the pumping means. These two trays include heating and regulating means. This device also comprises a delivery pipe connected to the pumping means for discharging the products and a pipe located in the head, connecting this delivery pipe to the interior cavity, and on which are located means for controlling and controlling the pressure of the products in the discharge line.
De préférence, entre ces deux plateaux est disposé au moins un bourrelet qui constitue un joint d'étanchéité entre cette tête et la paroi du récipient à vider. Preferably, between these two plates is disposed at least one bead which constitutes a seal between this head and the wall of the container to be emptied.
Avantageusement, cette tête est suspendue par au moins deux montants à un portique reposant sur au moins deux vérins et sur lequel sont disposés un moteur pour entraîner à vitesse constante les moyens de pompage ainsi qu'un ensemble dans lequel aboutit la conduite de refoulement. Advantageously, this head is suspended by at least two uprights from a gantry resting on at least two jacks and on which are arranged a motor for driving the pumping means at constant speed as well as an assembly in which the delivery pipe ends.
De préférence, cet ensemble comporte un bloc de filtration. Preferably, this assembly comprises a filtration block.
Avantageusement, la tête comporte des purges permettant la mise à l'airs d'une part, de la cavité intérieure et, d'autre part, de l'espace délimité par le plateau inférieur et le fond du récipient à vider. Advantageously, the head includes purges allowing the airing on the one hand, of the interior cavity and, on the other hand, of the space delimited by the lower plate and the bottom of the container to be emptied.
La description qui va suivre et qui ne présente aucun caractère limitatif,doit être lue en regard de la figure unique annexée gui représentelvue en coupe terticale,un dispositif selon la présente invention disposé dans un récipient ou fût renfermant un produit thermofusible. The description which follows and which does not have any limiting character, must be read with reference to the single appended figure which is shown in tertiary section, a device according to the present invention placed in a container or barrel containing a hot-melt product.
Ce dispositif comprend des moyens de page tels qutune pompe à engrenage 1, située sensiblement au sommet d'une tête désignée dans son ensemble par la référence 2. This device comprises page means such as a gear pump 1, located substantially at the top of a head designated as a whole by the reference 2.
Ces moyens de pompage comportent une conduite d'aspiration 3 et une conduite de refoulement 4,avantageusement rigide,du produit thermofusible contenu dans un récipient 5 à vider. These pumping means comprise a suction pipe 3 and a delivery pipe 4, advantageously rigid, of the hot-melt product contained in a container 5 to be emptied.
La tête 2 est constituée d'un plateau suprieur 6 relié à un plateau inférieur perforé 7 ; ces plateaux délimitent entre eux une cavité intérieure 8 dans laquelle débouche la conduite d'aspiration 3. Entre les deux plateaux est disposé un bourrelet 9 qui constitue un joint d'étanchéité entre la tête 2 et la paroi du récipient 5. The head 2 consists of an upper plate 6 connected to a perforated lower plate 7; these plates delimit between them an interior cavity 8 into which the suction pipe 3 opens. Between the two plates is a bead 9 which constitutes a seal between the head 2 and the wall of the container 5.
Les plateaux supérieur 6 et inférieur 7 comportent tous deux des moyens de chauffage et de régulation thermique.The upper 6 and lower 7 plates both include heating and thermal regulation means.
Cette tête 2 est, selon cet exemple de réalisation, suspendue à un portique 10 par deux montants 11 et 12. Ce portique repose sur un socle 13 par l'intermée diaire d'au moins deux vErins désignXs par la même référence 14. This head 2 is, according to this exemplary embodiment, suspended from a gantry 10 by two uprights 11 and 12. This gantry rests on a base 13 by means of at least two jacks designated by the same reference 14.
Sur ce portique 10 sont situés des moyens, tels qu'un moteur électrique 15, pour entrainer à vitesse constante les moyens de pompage 1 ainsi qu'un ensemble dans lequel débouche la conduite de refoulement 4. Cet ensemble peut notamment comprendre un bloc de filtration 16.De cet ensemble part au moins une tuyauterie souple 17. On this gantry 10 are located means, such as an electric motor 15, for driving the pumping means 1 at constant speed as well as an assembly into which the discharge pipe 4 opens. This assembly may in particular include a filtration block 16.At least one flexible pipe 17 starts from this assembly.
La conduite de refoulement 4 et la tuyauterie souple 17 sont entourées d'une gaine 18 comportant des moyens connus en eux-mêmes pour maintenir celle-ci à une température telle que le produit qui s'y trouve, soit à l'état liquide ou pâteux. The discharge pipe 4 and the flexible pipe 17 are surrounded by a sheath 18 comprising means known in themselves for maintaining the latter at a temperature such that the product which is there, either in the liquid state or pasty.
La mise en oeuvre d'un tel dispositif a lieu selon les modalités suivantes. The implementation of such a device takes place according to the following methods.
Le portique 10 étant en position haute c'est-à-dire les vérins 14 à leur maximum d'allongement, on dispose entre cesKvérins un récipient 5 contenant un produit thermofusible à vidanger.Le portique 10 est alors abaissé de telle sorte que le plateau inférieur 7 de la tête 2 vient au contact de la surface supérieure du produit thermofusible contenu dans le récipient 5. The gantry 10 being in the high position, that is to say the jacks 14 at their maximum elongation, there is between these Kverins a container 5 containing a hot-melt product to be drained. The gantry 10 is then lowered so that the plate lower 7 of head 2 comes into contact with the upper surface of the hot-melt product contained in container 5.
En mettant en oeuvre les moyens de chauffage inclus dans les plateaux 6 et 7, on réalise une fusion de la couche superficielle du produit thermofusible. By using the heating means included in the plates 6 and 7, the surface layer of the hot-melt product is fused.
Le produit liquide ainsi obtenu peut pénétrer dans la cavité interne 8 en passant au travers du plateau inférieur perforé 7. L'air contenu dans la cavité intérieure 8 peut s'échapper par la purge 19 ménagée dans le plateau supérieur 6.The liquid product thus obtained can penetrate into the internal cavity 8 by passing through the perforated lower plate 7. The air contained in the internal cavity 8 can escape through the drain 19 formed in the upper plate 6.
Au fur et à mesure que du produit thermofusible est liquéfié on enfonce la tête 2 dans ce produit. As the hot-melt product is liquefied, the head 2 is pushed into this product.
Dès que la cavité interne 8 est remplie,on met en route les moyens de pompage 1 de façon à évacuer le produit liquide par la conduite de refoulement 4 et la tuyauterie souple 17.As soon as the internal cavity 8 is filled, the pumping means 1 are started up so as to evacuate the liquid product via the discharge line 4 and the flexible pipe 17.
En fonction des besoins en produit, il est possible de régler le débit du produit pompé grâce à des moyens de commande et de régulation 2Q disposés sur une conduite 21 reliant la conduite de refoulement 4 à la cavité interne 8. Depending on the product requirements, it is possible to adjust the flow rate of the pumped product by means of 2Q control and regulation means disposed on a line 21 connecting the discharge line 4 to the internal cavity 8.
Ces moyens de commande et de régulation peuvent être avantageusement ceux décrits dans le brevet français NO 75 28 565. These control and regulation means may advantageously be those described in French patent NO 75 28 565.
Le flux de produit liquide passant par la conduite 21 entraîne dans la cavité interne 8 une homogénéisation du produit s'y trouvant ainsi que des températures. The flow of liquid product passing through the line 21 causes in the internal cavity 8 a homogenization of the product therein as well as temperatures.
Le bourrelet 9 assurant l'étanchéité entre la tête 2 et la paroi du récipient 5 s'oppose à une remontée du produit liquéfié. The bead 9 ensuring the seal between the head 2 and the wall of the container 5 is opposed to a rise in the liquefied product.
Quand la tête 2 est arrivée au fond du récipient 5, et afin d'en permettre la remontée il est prévu une mise à l'air grâce à une purge 22 située dans la tête 2. When the head 2 has arrived at the bottom of the container 5, and in order to allow it to rise, an air vent is provided by means of a drain 22 located in the head 2.
