Description

Dispositif de projection de jets à double obturationDouble shutter jet projection device
La présente invention se rapporte aux dispositifs de projection de jets d'eau, utiles notamment pour le liage hydraulique de fibres en des non- tissés. Ce liage consiste à envoyer un rideau de jets d'eau sous pression sur un nappe de fibres pour les enchevêtrer et les former en une nappe cohérente, sans nécessiter l'utilisation de liants ou de résines. On peut lier aussi de la matière en feuille telle que des complexes textiles, des fils, du papier, des tissus, des tricots.The present invention relates to devices for spraying water jets, useful in particular for the hydraulic bonding of fibers in nonwovens. This binding consists of sending a curtain of pressurized water jets onto a sheet of fibers to entangle them and form them into a coherent sheet, without requiring the use of binders or resins. It is also possible to bind sheet material such as textile complexes, threads, paper, fabrics, knits.
On connaît déjà un dispositif de projection de jets d'eau comprenant un corps délimitant une chambre de réception d'un filtre. La chambre débouche, avec interposition d'une plaque perforée créant les jets d'un diamètre approprié, sur une face principale du corps et, par une ouverture pouvant être obturée par un premier bouchon amovible, du côté d'une face frontale du corps. La plaque perforée est montée coulissante dans un logement débouchant, par un trou pouvant être obturé par un second bouchon, du côté de la face frontale du corps.There is already known a device for projecting water jets comprising a body delimiting a chamber for receiving a filter. The chamber opens, with the interposition of a perforated plate creating the jets of an appropriate diameter, on a main face of the body and, by an opening that can be closed by a first removable plug, on the side of a front face of the body. The perforated plate is slidably mounted in a through housing, through a hole which can be closed off by a second plug, on the side of the front face of the body.
L'invention vise à simplifier la fabrication d'un dispositif de projection de jets d'eau de ce genre, ainsi qu'à faciliter le remplacement de la plaque perforée et du filtre lorsqu'ils doivent être remplacés tous les deux ou seulement de la plaque perforée.The invention aims to simplify the manufacture of a device for projecting such water jets, as well as to facilitate the replacement of the perforated plate and the filter when they have to be replaced both or only from the perforated plate.
On y parvient suivant l'invention par le fait que l'ouverture et le trou débouchent dans un même puits ménagé dans le corps et muni d'une contre-ouverture et d'un contre-trou en regard de l'ouverture et du trou respectivement, et une goupille est insérée de manière amovible dans le puits dans des perçages des bouchons, de façon à y maintenir les deux bouchons en position d'obturation quand elle y est insérée complètement.This is achieved according to the invention by the fact that the opening and the hole open into the same well formed in the body and provided with a counter-opening and a counter-hole opposite the opening and the hole. respectively, and a pin is removably inserted into the well in the holes of the plugs, so as to keep the two plugs in the closed position when it is fully inserted therein.
Comme le puits est ménagé dans le corps, on se dispense d'une pièce supplémentaire rapportée à visser pour la fabrication. On peut remplacer la plaque perforée en faisant coulisser la goupille parallèlement à son axe longitudinal pour qu'elle sorte du perçage ménagé dans le second bouchon tout en restant dans le perçage ménagé dans le premier bouchon, de sorte que le bouchon destiné à la chambre de réception du filtre reste en place. Si néanmoins on souhaite remplacer aussi le filtre, on retire davantage la goupille. Les parois du puits unique maintiennent une goupille unique qui maintient les deux bouchons. On retire les bouchons en les faisant sortir respectivement de l'ouverture et de la contre-ouverture et du trou et du contre- trou.As the well is formed in the body, there is no need for an additional insert piece to be screwed for manufacturing. The perforated plate can be replaced by sliding the pin parallel to its longitudinal axis so that it comes out of the hole made in the second plug while remaining in the hole made in the first plug, so that the plug intended for the the filter remains in place. However, if you also want to replace the filter, you remove the pin further. The walls of the single well maintain a single pin which holds the two plugs. The plugs are removed by removing them respectively from the opening and the counter-opening and from the hole and the counter- hole.
Suivant un mode de réalisation simple, des premiers moyens bloquent la goupille en la position où elle maintient les deux bouchons en position d'obturation et des seconds moyens bloquent la goupille en une position intermédiaire où elle maintient le premier bouchon en position d'obturation de l'ouverture et cesse de maintenir le second bouchon en position d'obturation du trou. Les premiers et les seconds moyens sont constitués par exemple de rainures périphériques respectives ménagées sur la face extérieure de la goupille et coopérant avec un doigt amovible pénétrant radialement dans les rainures et pouvant être manœuvrées manuellement de l'extérieur.According to a simple embodiment, first means block the pin in the position where it keeps the two plugs in the closed position and second means block the pin in an intermediate position where it keeps the first plug in the closed position of the opening and stops holding the second plug in the closed position of the hole. The first and second means consist for example of respective peripheral grooves formed on the outside face of the pin and cooperating with a removable finger penetrating radially into the grooves and being able to be operated manually from the outside.
Suivant un perfectionnement qui apporte une grande sécurité vis-à-vis des accidents auxquels est exposé l'opérateur en raison des grandes pressions qui régnent dans la chambre," la goupille agit sur une commande d'un dispositif d'alimentation en eau sous pression de la chambre en n'autorisant l'alimentation que lorsqu'elle est insérée complètement dans le puits. La goupille peut constituer l'organe de manœuvre d'un interrupteur d'un circuit électrique de commande du dispositif d'alimentation en eau ou son déplacement peut envoyer un signal à une unité de commande qui commande le dispositif d'alimentation en eau.According to an improvement which brings great safety with regard to accidents to which the operator is exposed due to the high pressures which reign in the chamber, " the pin acts on a command of a device for supplying water under pressure. of the chamber by authorizing the supply only when it is fully inserted into the well. The pin may constitute the operating member of a switch of an electric circuit for controlling the water supply device or its displacement can send a signal to a control unit which controls the water supply device.
La figure unique du dessin annexé, est une vue en coupe partielle à l'échelle 1/3, à l'exception de l'alimentation en eau, d'un dispositif de projection de jets d'eau suivant l'invention.The single figure of the appended drawing is a partial sectional view on a 1/3 scale, with the exception of the water supply, of a device for projecting water jets according to the invention.
Le dispositif de projection de jets suivant l'invention comprend un corps 1 parallelepipedique ayant deux faces 2, 3 principales opposées, deux petites faces opposées qui n'apparaissent pas au dessin et qui sont disposées dans des plans parallèles au plan du dessin et deux faces 4 frontales opposées dont celle de droite seulement apparaît au dessin. Le corps est en acier. Dans le corps est forée une chambre 5 oblongue de section droite circulaire et d'axe X-X' qui va d'une face frontale 4 à l'autre. Dans la face frontale 4 qui n'est pas vraiment représentée à la figure mais qui est symbolisée par la ligne 6 en trait mixte de coupe est ménagé un raccord symbolisé par la ligne 7 menant à une source 8 d'eau sous pression qui est commandée par un dispositif 9 de commande. Dans la chambre 5 est disposé un filtre 10 cylindrique de même forme que la chambre 5 mais de plus petit diamètre. La face 3 du corps est constituée d'un mors 11 qui est vissé au reste du corps 1 par des vis.The device for projecting jets according to the invention comprises a parallelepipedic body 1 having two opposite faces 2, 3, two opposite small faces which do not appear in the drawing and which are arranged in planes parallel to the drawing plane and two faces 4 opposite fronts of which only the right one appears in the drawing. The body is made of steel. In the body is drilled an oblong chamber 5 of circular cross section and axis XX 'which goes from one front face 4 to the other. In the front face 4 which is not really represented in the figure but which is symbolized by the line 6 in phantom of cut is provided a connection symbolized by the line 7 leading to a source 8 of pressurized water which is controlled by a control device 9. In the chamber 5 is arranged a cylindrical filter 10 of the same shape as the chamber 5 but of smaller diameter. The face 3 of the body consists of a jaw 11 which is screwed to the rest of the body 1 by screws.
Un canal 12 en forme de fente s'étendant sur une génératrice ou sur deux génératrices adjacentes de la chambre mène de la chambre 5 à une ouverture 13 en forme de fente ménagée dans la face 3 et débouchant à l'extérieur.A slot-shaped channel 12 extending over one generator or over two adjacent generators of the chamber leads from the chamber 5 to a slot-shaped opening 13 formed in the face 3 and opening to the outside.
Le mors 11 délimite une cavité dans laquelle est logée une plaque 15 perforée de microperforations dont le diamètre est compris entre 50 et 500 μm et de préférence entre 100 et 200 μm, qui permet de former des jets ou des aiguilles d'eau. Ces perforations sont disposées suivant une rangée ou suivant deux rangées parallèles à l'axe X-X' et en regard de la fente 12.The jaw 11 delimits a cavity in which is housed a plate 15 perforated with microperforations whose diameter is between 50 and 500 μm and preferably between 100 and 200 μm, which makes it possible to form jets or needles of water. These perforations are arranged in a row or in two rows parallel to the axis XX ′ and facing the slot 12.
La plaque 15 perforée est montée coulissante parallèlement à l'axe X-X' dans un logement 16 délimité dans le corps 1. La chambre 5 débouche du côté de la face 4 frontale du corps par l'intermédiaire d'une ouverture 17 dans un perçage 18 foré dans le corps 1. L'ouverture 17 peut être bouchée par un premier bouchon 19 muni d'un perçage dans lequel passe une goupille 20 pénétrant dans le perçage 18.The perforated plate 15 is slidably mounted parallel to the axis XX 'in a housing 16 delimited in the body 1. The chamber 5 opens on the side of the front face 4 of the body via an opening 17 in a bore 18 drilled in the body 1. The opening 17 can be plugged by a first plug 19 provided with a hole through which a pin 20 passes penetrating the hole 18.
De la même façon, un second bouchon 21 bouche l'ouverture 22 du logement et comporte un perçage dans lequel passe aussi un tronçon 23 d'extrémité de la goupille 20 qui est plus étroit que le reste de la goupille 20. En regard de l'ouverture 17, est ménagée dans le corps 1 une contre- ouverture 24 de même dimension, qui se trouve de l'autre côté du puits, et dans lequel s'étend le premier bouchon 29. En regard du trou 22 est ménagé un contre-trou 25, dans lequel s'étend le second bouchon 21. Chaque bouchon est muni à l'extérieur d'une manette 26, 27 permettant de le faire coulisser facilement parallèlement à l'axe X-X'.In the same way, a second plug 21 blocks the opening 22 of the housing and has a bore through which also passes a section 23 of the end of the pin 20 which is narrower than the rest of the pin 20. Opposite the opening 17 is formed in the body 1 a counter opening 24 of the same dimension, which is located on the other side of the well, and in which the first plug 29 extends. Opposite the hole 22 is formed a counter hole 25, in which extends the second plug 21. Each plug is provided on the outside with a lever 26, 27 allowing it to slide easily parallel to the axis XX ′.
Sur la face latérale de la goupille est ménagée une première rainure 28 et une seconde rainure 29 périphérique, la rainure 29 étant plus près du tronçon 23 que ne l'est la rainure 28. Un doigt 30 pouvant être manœuvré à la main traverse la paroi du puits 18 et son extrémité peut pénétrer dans l'un des rainures 28 ou 29 lorsque la rainure se trouve en regard du doigt et bloquer ainsi la goupille en position. Lorsque, comme représenté sur la figure, le doigt 30 pénètre dans la rainure 28, la goupille est bloquée en sorte qu'elle maintient les premier et second bouchons 19 et 21 en une position d'obturation respectivement de la chambre 5 et du logement 16. Lorsque l'on remonte la goupille 20 en retirant le doigt 30 de manière à permettre le mouvement, la rainure 29 vient en regard du doigt 30. On ramène alors le doigt 30 à l'intérieur du puits. La goupille est alors bloquée en une seconde position dans laquelle elle continue à maintenir le premier bouchon 19 mais elle dégage le bouchon 21 que l'on peut retirer par le contre-trou 25 et accéder ainsi à la plaque 15 perforée pour la remplacer.On the lateral face of the pin is formed a first groove 28 and a second peripheral groove 29, the groove 29 being closer to the section 23 than is the groove 28. A finger 30 which can be operated by hand passes through the wall of the well 18 and its end can penetrate into one of the grooves 28 or 29 when the groove is opposite the finger and thus lock the pin in position. When, as shown in the figure, the finger 30 enters the groove 28, the pin is locked so that it maintains the first and second plugs 19 and 21 in a closed position of the chamber 5 and of the housing 16 respectively. . When the pin 20 is raised by removing the finger 30 so as to allow movement, the groove 29 comes opposite the finger 30. The finger 30 is then brought back inside the well. The pin is then locked in a second position in which it continues to hold the first plug 19 but it releases the plug 21 which can be removed by the counter-hole 25 and thus access the perforated plate 15 to replace it.
Lorsque enfin on retire complètement la goupille du perçage 18, elle cesse de maintenir le premier bouchon 19 que l'on peut retirer avec possibilité d'accéder au filtre 10 et de le retirer par la contre-ouverture 24. La goupille 18 comporte une poignée de manœuvre 31 facilitant sa manœuvre et il en part une ligne électrique 32 qui envoie un signal au dispositif 9 de commande lorsque la goupille 18 n'est pas en la position, représentée à la figure, d'insertion complète dans le puits 18 où elle maintient les deux bouchons 19 et 21. Le bouchon 21 peut éventuellement faire partie du corps 1 ou du mors 11. When finally the pin is completely removed from the bore 18, it ceases to hold the first plug 19 which can be removed with the possibility of accessing the filter 10 and removing it through the counter-opening 24. The pin 18 has a handle maneuver 31 facilitating its maneuver and there is an electric line 32 which sends a signal to the control device 9 when the pin 18 is not in the position, shown in the figure, of complete insertion into the well 18 where it holds the two plugs 19 and 21. The plug 21 may possibly be part of the body 1 or of the jaw 11.
