Abstract

The track (5) guided carriage (3) supports the main feed pipe (1) of a pneumatic conveyor, moves the main pipe over the open ends of ancillary pipes (2a-2f) to alternative storage silos, and is equipped to connect the main pipe to the ancillary pipe over which it locates. A main pipe end fitting (14,15) is mounted slidably on the carriage, being built into the piston (18) of a pneumatic ram of which the carriage substructure forms the casing (17,13). The jack is used to withdraw the fitting whilst a spring (28) moves it forward to seal onto the relevant ancillary pipe end (16). A roller (12) mounted on a finger (10) may enter a flare-mouth (9) recess (8) to locate the carriage relative to the ancillary pipe, longitudinal play relative to the drive chain (6) being provided by a spring piston coupling (34-35).

Description

APPAREILLAGE DE RACCORDEMENT POUR
TRANSPORTEUR PNEUMATIQUE
L'invention a pour objet un appareillage de raccordemont pour transporteur pneumatique.
CONNECTION APPARATUS FOR
PNEUMATIC CONVEYOR
The subject of the invention is a fitting device for a pneumatic conveyor.

Les transporteurs pneumatiques sont couramment utilisés pour le transport de produits en grain. ou en poundre. Ils comportent essentiellement un réseau tubulaire qui est issu d'un poste a ont de stockage, aboutit å un poste aval de stockage ou d'utilisation et dans lequel est créée une dépression réalisant le transport du porduit
Pour éviter la présence d'un réseau multitubulaire entre plusieurs postes a ont et un poste aval ou l'un ou l'autre de plusieurs postes aval, il n'est possible d'utiliser ùn réseau monotubulaire que si à l'extrémité amont de ce réseau est prévu un appareillage permettant son raccorderent à volonté à l'un ou a l'autre des postes a ont.
Pneumatic conveyors are commonly used to transport grain products. or in poundre. They essentially comprise a tubular network which comes from a storage station, leads to a downstream storage or use station and in which a depression is created carrying out the transport of the product.
To avoid the presence of a multitubular network between several stations a and a downstream station or one or the other of several downstream stations, it is only possible to use a monotube network if at the upstream end of this network is provided with an apparatus allowing its connection at will to one or the other of the stations has.

L'invention a précisément pour objet un appareillage permettant ce raccord--ont dans des conditions parfaites d'étanchéité pour l'air et pour le produit à transporter. The subject of the invention is precisely an apparatus allowing this connection - have in perfect sealing conditions for the air and for the product to be transported.

Dans cet appareillage, un embout solidaire du tube de transport et se terminant par une embouchure alignée avec celle de l'un ou l'autre des tubes amount est port par un chariot qui est monté mobile sur un chemin fixe et dans lequel est aménagé un cylindre dont le piston est constite par une partie annulaire de cet embout et est soumis å l'action d'un ressort de rappel tendant à maintenir l#embouchure du tube de transport en correspondance avec celle d'un tube amont, la séparation passagère des deux embouchures résultant de l'admission d'air com- prie dans le cylindre précité. In this apparatus, an end piece integral with the transport tube and ending in a mouth aligned with that of one or the other of the upright tubes is carried by a carriage which is movably mounted on a fixed path and in which is arranged a cylinder whose piston is formed by an annular part of this endpiece and is subjected to the action of a return spring tending to keep the mouth of the transport tube in correspondence with that of an upstream tube, the temporary separation of the two mouths resulting from the admission of air into the aforementioned cylinder.

an position normale de transport du produit ou de repos, le tube de transport est donc en communication constante avec l'un ou l'autre des tubes aont ; et c'est s-ule-ent lorsque de l'air %comprimé est envoyé dans le cylindre de l'appareillage que l'embouchure du tube de transport se dégage hors de celle de l'un des tubes a ont et peut alors par translation du chariot être amenée en regard de celle d'un autre tube amont. in the normal product transport or rest position, the transport tube is therefore in constant communication with one or the other of the aont tubes; and it is only when compressed air is sent into the cylinder of the apparatus that the mouth of the transport tube emerges from that of one of the tubes has and can then by translation of the carriage be brought opposite that of another upstream tube.

Conformément à l'invention, des moyens comlémentaireg sont d'ailleurs prévus pour que, après chaque déplace- ment du chariot, il y ait concordance parfaite entre les embouchures du tube de transport et du tube amont sélec- tionné. In accordance with the invention, additional means are also provided so that, after each movement of the carriage, there is perfect agreement between the mouths of the transport tube and the selected upstream tube.

Ces noyons sont constitués, en combinaison, par un logement associé à chaque tube amont,,par deux rampes d'accès à chacun de Ces logements et par un doigt qui, solidaire du chariot portant l'embout du tube de trans- port, pénètre sous l'action du ressort de rappel de cet embout au fond du logement correspondant au tube a ont sélectionné et positionne ainsi cet embout, des Moyens élastiques étant interposés entre le chariot et le ou les organes provoquant son déplacement, afin de permettre un décalage dans la position respective de cet embout et de ce ou ces organes. These cores are constituted, in combination, by a housing associated with each upstream tube, by two ramps for access to each of these housings and by a finger which, integral with the carriage carrying the end piece of the transport tube, penetrates under the action of the return spring of this end piece at the bottom of the housing corresponding to the tube a have selected and thus positions this end piece, elastic means being interposed between the carriage and the member or members causing its displacement, in order to allow a shift in the respective position of this nozzle and this or these organs.

L'invention sera bien comprise d'ailleurs å l#aide de la description qui suit, on référence au dessinssché- -matique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cet appareillage s
Figures 1 et 2 en sont des vues respectivement en plan par dessus et en coupe verticale on position de raccordement d'un tube amoubt avec le tube de départ, c'est-à-dire le tube de transport
Figures 3 et 4 sont les mêmes vues on position de séparation du tube de départ par rapport a l'un des tubes a ont, e'est-Adir- dans une position correspondant à un changement de raccordement.
The invention will be understood moreover by means of the description which follows, reference is made to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of this apparatus.
Figures 1 and 2 are views respectively in plan from above and in vertical section in position of connection of a softened tube with the starting tube, that is to say the transport tube
Figures 3 and 4 are the same views of the separation position of the starting tube with respect to one of the tubes has, is Adir- in a position corresponding to a change of connection.

Dans ce dessin, (1) désigne un tube destiné au transport d'un produit pulvérulent ou d'un produit on grains. Ce tube est appelé à être raccordé à l'un à l'autre de plusieurs tubes (2a) (2b)(2c) (20)(20) (2f) qui chacun proviennent par exemple d'un silo. Entre le tube de transport (i) et les tubes (2a...2f) est interposé l'appareillage qui fait Itobjet de l'invention et qui permet de raccorder le tube (i) à volonté à l'un ou à l'autre des tubes (2a. . 2f).  In this drawing, (1) denotes a tube intended for the transport of a pulverulent product or of a grain product. This tube is called to be connected to one another by several tubes (2a) (2b) (2c) (20) (20) (2f) which each come for example from a silo. Between the transport tube (i) and the tubes (2a ... 2f) is interposed the apparatus which is the object of the invention and which makes it possible to connect the tube (i) at will to one or to the other of the tubes (2a.. 2f).

Cet appareillage est porté par un chariot qui est désigné de façon générale par (3) et qui est équipé de galets (4) lui permettant de se déplacer sur un rail en
I (5) sous l'effet d'une chaîne de traction (6).
This apparatus is carried by a trolley which is generally designated by (3) and which is equipped with rollers (4) allowing it to move on a rail in
I (5) under the effect of a traction chain (6).

Au rail (5) est associe un deuxième rail (7) qui est situé en dessous des tubes (2a. 2f) et dans lequel sont aménagés des logements (8) dont le nombre est égal
A celui des tubes (2a...2f). L'écartement de ces loge mentis est égal à celui de ces tubes ; et sur leur face dirigée verslle tube de transport (i) ils présentent chacun une. entrée évasée (9) dont les deux bords verti caux constituent deux rampes obliques permettant d'accéder auxlogements (8).
A second rail (7) is associated with the rail (5) which is located below the tubes (2a. 2f) and in which are housed (8) the number of which is equal.
To that of the tubes (2a ... 2f). The spacing of these lodges is equal to that of these tubes; and on their face directed towards the transport tube (i) they each have a. flared entry (9), the two vertical edges of which constitute two oblique ramps providing access to the housings (8).

Avec l'un ou l'autre de ces logements (8) est appelé coopérer un doigt (10) dont l'extrémité est porteuse d'un galet (12). Ce doigt est indirectement porté, comme il sera ci-après décrit, par le chariot (3) et permet précisément de bien positionner ce chariot pour que le tube de transport (i) soit parfaitement aligné avec l'un ou l'autre des tubes (2a...2f). With one or the other of these housings (8) is called cooperate a finger (10) whose end carries a roller (12). This finger is indirectly carried, as will be described below, by the carriage (3) and precisely makes it possible to correctly position this carriage so that the transport tube (i) is perfectly aligned with one or the other of the tubes. (2a ... 2f).

Le chariot (3) est équipé d'un flasque annulaire (13) grâce auquel il porte un embout tubulaire (14) sur lequel est emmanchée l'extrémité amont du tube de transport (i). Cet embout (il) se termine par une embouchure (15) qui est destinée à coopérer avec l'une ou l'autre (16) des embouchures des tubes (2a...2f). Dans la position représentée aux figures 1 et 2, l'embouchure (15) de l'embout (18) est en prise avec l'embouchure (16) du tube aont (2c). The carriage (3) is equipped with an annular flange (13) by which it carries a tubular end piece (14) on which is fitted the upstream end of the transport tube (i). This nozzle (it) ends with a mouth (15) which is intended to cooperate with one or the other (16) of the mouths of the tubes (2a ... 2f). In the position shown in Figures 1 and 2, the mouth (15) of the tip (18) is engaged with the mouth (16) of the aont tube (2c).

Le chariot (3) porte d'autre part une pièce annulaire (17) dont la face intérieure constitue une chemise cylindrique dans laquelle est appelé A se déplacer en translation un piston annulaire (18) porté par l'embout (14).  The carriage (3) also carries an annular part (17) whose inner face constitutes a cylindrical jacket in which is called A displacement in translation an annular piston (18) carried by the end piece (14).

Les deux pièces annulaires (13) et (17) délimitent un cylindre qui est relié à une source d'air comprimé par une canalisation (19) ; et lorsque de l'air comprimé est envoyé dans ce cylindre, comme le montre la flèche (21) de la figure 4, le piston (t8) et l'embout (14) du tube (i) sont ainsi amenés à se déplacer dans le sens de la flèche (22) de cette figure 41 ce qui entraine le dégagement de l'embouchure (15) hors de celle (16). The two annular parts (13) and (17) define a cylinder which is connected to a source of compressed air by a pipe (19); and when compressed air is sent into this cylinder, as shown by the arrow (21) in FIG. 4, the piston (t8) and the end piece (14) of the tube (i) are thus caused to move in the direction of the arrow (22) in this figure 41 which causes the mouth (15) to be released from that (16).

Le chariot (3) porte enfin un flasque (23) dans lequel sont montées coulissantes la tige précités (10) et une tige (24). Ces deux tiges sont solidaires d'un flasque (25) fixé sur l'embout (14) ; et à l'extrémité de la tige (24) est vissé un écrou (26) retenant une rondelle (27) sur laquelle prend appui l'une des extrémités d'un ressort (28) dont l'autre extrémité prend appui sur le flasque (23). Le ressort (28) prenant ainsi appui fixe sur le flasque (23) du chariot (3) tend à déplacer la tige (24) dans le sens de la flèche (29) de la figure 2, ce qui a pour but de maintenir l'embouchure (15) de l'embout (14) en prise avec l'embouchure (16) du tube (2c) et ce comme le montre cette figure 2.  The carriage (3) finally carries a flange (23) in which the above-mentioned rod (10) and a rod (24) are slidably mounted. These two rods are integral with a flange (25) fixed on the end piece (14); and at the end of the rod (24) is screwed a nut (26) retaining a washer (27) on which is supported one of the ends of a spring (28) whose other end is supported on the flange (23). The spring (28) thus taking fixed support on the flange (23) of the carriage (3) tends to move the rod (24) in the direction of the arrow (29) of Figure 2, which aims to maintain the 'mouth (15) of the nozzle (14) in engagement with the mouth (16) of the tube (2c) and this as shown in this figure 2.

C'est seulement lorsque de l'air comprimé est envoyé dans le cylindre délimité par les organes (13) et (17) que le piston (lô) se déplace dans le sens de la flèche (22) et entrain avec lui les deux tiges (2i) et (10). It is only when compressed air is sent into the cylinder delimited by the members (13) and (17) that the piston (lô) moves in the direction of the arrow (22) and carries with it the two rods (2i) and (10).

Durantson déplacement, la tige (24) augmente la compression du ressort (28), ce qui facilitera le retour de l'embout (14) en position de branchement lorsque ces- sera l'arrivée d'air comprimé dans le cylindre. De son côté, lorsque le doigt (10) est entratné a se déplacer dans le sens de la flèche (22), son extrémité équipé- du galet (12) se dégage hors du logement (8) au fond duquel elle se trouvait.  During its displacement, the rod (24) increases the compression of the spring (28), which will facilitate the return of the end piece (14) in the connection position when the arrival of compressed air in the cylinder. For its part, when the finger (10) is driven to move in the direction of the arrow (22), its end equipped with the roller (12) emerges from the housing (8) at the bottom of which it was located.

Lorsque cesse la poussée de l'air comprimé sur le piston (18) et donc le déplacement de l'embout (14), la détente du ressort (28) ramène l'embout (14) en position de branchement ; et c'est alors qu'intervient l'action du doigt (10) qui, par son galet (12) permet un bon centrage de l'embout (14) afin que son embouchure (15) vienne en concordance rigoureuse avec celle (16). When the pressure of the compressed air on the piston (18) and therefore the displacement of the end piece (14) ceases, the relaxation of the spring (28) returns the end piece (14) to the connection position; and it is then that the action of the finger (10) comes into play which, by its roller (12) allows good centering of the end piece (14) so that its mouthpiece (15) comes into strict agreement with that (16 ).

C'est grâce aux deux rampes constituées par l'entrée évasée (9) du logement (8) qu'il est possible d'obtenir une parfaite concordance entre l'axe de l'embout (14) et l'axe du tube (2c). It is thanks to the two ramps formed by the flared entry (9) of the housing (8) that it is possible to obtain perfect concordance between the axis of the nozzle (14) and the axis of the tube ( 2c).

Pour obtenir ce centrage rigoureux, des moyens doivent cependant atre prévus pour qu'il y ait une cer taine élasticité dans la liaison entre le chariot (3) et son organe de commande de translation, A savoir la channe (6). Pour ce faire, la channe (6) porte un doigt (31) qui traverse une fente aménagée dans le chariot (3) et qui est solidaire d'une pièce (32) présentant deux or permettant sa fixation sur une tige (33). To obtain this rigorous centering, means must however be provided so that there is a certain elasticity in the connection between the carriage (3) and its translation control member, namely the chain (6). To do this, the chain (6) carries a finger (31) which passes through a slot in the carriage (3) and which is integral with a part (32) having two gold allowing its attachment to a rod (33).

Cette tige est montée coulissante dans deux paliers (34) portés par le chariot (3) ; et un ressort (35) est inter- posé entre chaque palier (34) et la pièce centrale (32).This rod is slidably mounted in two bearings (34) carried by the carriage (3); and a spring (35) is interposed between each bearing (34) and the central part (32).

Dans la position représentée aux figures 3 et e, l'embout (14) est débranché hors de l'embouchure (16) du tube (2c) en raison de la présence d'air comprimé dans le cylindre délimité par les organes (13) et (17) t et la chaîne (6) est sensée atre immobile. Le chariot (3) occupe une position dans laquelle son doigt (10) n'est pas forcément en alignement rigoureux avec le logement (8) correspondant à celui des tubes (2a ... 2f) avec lequel le tube de transport (1) doit atre mis en commu- nication.Ce désalignement entre le tube de transport (î) et le tube correspondant (2c) est visible A la figure 3. In the position shown in FIGS. 3 and e, the end piece (14) is disconnected outside the mouth (16) of the tube (2c) due to the presence of compressed air in the cylinder delimited by the members (13) and (17) t and the chain (6) is supposed to be immobile. The carriage (3) occupies a position in which its finger (10) is not necessarily in rigorous alignment with the housing (8) corresponding to that of the tubes (2a ... 2f) with which the transport tube (1) This misalignment between the transport tube (î) and the corresponding tube (2c) is visible in Figure 3.

il n'en demeure pas moins que, dès l'instant où cesse l'action de l'air comprimé dans le cylindre délimité par les organes (13) et (17), le ressort (28) jouera son rôle de rappel en position de branchement avec la certitu- de qu'il y ait alors parfaite coincidence entre le tube (1) et le tube (2c). Ce résultat est obtenu grecs au doigt (10) qui, reprenant se position primitive lors de la détente du ressort (28), présente son galet (12) sur l'une des rampes d'accès auxlogements (8). Cette rampe conduit A un mouvement de translation latéral du doigt (10) et de l'ensemble du chariot (3). il v a donc bien finalement coïncidence rigoureuse entre le tube de transport (1) et le tube amont correspondant (2c). the fact remains that, as soon as the action of the compressed air in the cylinder delimited by the members (13) and (17) ceases, the spring (28) will play its role of return to position of connection with the certainty that there is then perfect coincidence between the tube (1) and the tube (2c). This result is obtained by the Greek finger (10) which, resuming its original position when the spring (28) is relaxed, presents its roller (12) on one of the access ramps to the housings (8). This ramp leads to a lateral translational movement of the finger (10) and of the entire carriage (3). there is therefore indeed a rigorous coincidence between the transport tube (1) and the corresponding upstream tube (2c).

Comme il va de soi, l'invention ne se limite pas A la seule forme d'exécution de cet appareillage de raccor- devent pour transporteur pneumatique qui a été ci-dessus décrite A titre d'exemple ; elle en embrasse au contraire toutes les variantes de réalisation.  It goes without saying that the invention is not limited to the sole embodiment of this fitting apparatus for pneumatic conveyor which has been described above by way of example; on the contrary, it embraces all of its variant embodiments.
