La présente invention concerne un convoyeur à pas de pèlerin, notamment bien que non exclusivement pour le traitement thermique de cartes électroniques dans un four de refusion. ARRIERE PLAN DE L'INVENTIONThe present invention relates to a pilgrim conveyor, particularly although not exclusively for the heat treatment of electronic boards in a reflow oven. BACKGROUND OF THE INVENTION
On connaît du document US 5 334 014 un convoyeur à pas de pèlerin comportant un châssis portant des rails supports fixes et des rails supports mobiles associés à des organes de levage et des organes de coulissement pour effectuer un déplacement des rails supports mobiles selon un mouvement de levage et un mouvement de coulissement séparés .Document US Pat.

Dans ce document, le convoyeur à pas de pèlerin est destiné à être utilisé dans un four de traitement à haute température (16000C) et la préoccupation principale est de protéger de la chaleur les différents composants du convoyeur. A cet effet les mouvements des rails supports mobiles sont obtenus en reliant ceux-ci à un mât central qui s'étend dans un puits en matière isolante et est relié aux organes de levage et de coulissement en dessous du puits.In this document, the pilgrim conveyor is intended to be used in a high temperature treatment furnace (1600 ° C.) and the main concern is to protect the various components of the conveyor from heat.

Compte tenu de la structure de ce convoyeur, il n'est pas possible d'assurer un guidage précis des articles transportés et il n'est donc pas possible d'envisa- ger son utilisation dans un four de refusion où les cartes électroniques doivent être déplacées avec une très grande précision entre des compartiments dont la température varie de façon très importante, typiquement de 8O0C à 3000C. OBJET DE L'INVENTIONGiven the structure of this conveyor, it is not possible to provide accurate guidance of the items being transported and it is therefore not possible to envisage its use in a reflow oven where the electronic boards must be displaced with very great precision between compartments whose temperature varies very significantly, typically from 80 ° C. to 300 ° C.

DESCRIPTION DETAILLEE DE L'INVENTION En référence à la figure 1, le châssis du convoyeur selon l'invention comporte une plaque de base frontale 101 verticale qui s'étend sur un côté du convoyeur. Les extrémités de la plaque de base frontale 101 sont reliées par des plaques entretoises 102, dont une seule est représentée sur la figure 1, à une plaque latérale supérieure 103 qui s'étend horizontalement au-dessus du côté du convoyeur opposé à la plaque de base frontale 101. La plaque de base frontale 101, les plaques entretoises 102 et la plaque latérale supérieure 103 constituent ainsi une partie de châssis formant un cadre généralement désigné par la référence numérique 104.
A mi-distance entre les plaques entretoises 102, une potence de référence 105 est rigidement fixée à la plaque de base frontale 101 par l'intermédiaire d'un bloc thermiquement isolant 106. Une plaque support allongée 16 thermiquement déformable, par exemple une plaque en aluminium, est disposée horizontalement selon une direction longitudinale du convoyeur et comporte une partie de référence centrale qui est rigidement fixée à la potence 105. La plaque support 16 s'étend de part et d'autre de la partie centrale de référence et supporte au voisinage de ses extrémités des potences 107 (dont une seule est représentée sur la figure 1) fixées à la plaque 16 et comportant à leur partie supérieure une aile horizontale prenant appui sur un bloc thermiquement isolant 108 fixé à la plaque de base frontale 101. La potence 107 est ainsi libre de coulisser lors des déformations longitudinales de la plaque support 16 sous l'effet de variations de températures. De cette façon on évite une déformation transversale de la plaque support 16 dans les zones de températures différentes traversées par la plaque support 16, et on évite la déformation qui serait engendrée par la différence de dilatation entre la plaque support 16 et la plaque de base 101.DETAILED DESCRIPTION OF THE INVENTION With reference to FIG. 1, the conveyor frame according to the invention comprises a vertical front base plate 101 which extends on one side of the conveyor. The ends of the front base plate 101 are connected by spacer plates 102, only one of which is shown in FIG. 1, to an upper side plate 103 which extends horizontally above the opposite side of the conveyor plate. front base 101. The front base plate 101, the spacer plates 102 and the upper side plate 103 thus constitute a frame portion forming a frame generally designated by the numeral 104. At mid-distance between the spacer plates 102, a reference bracket 105 is rigidly fixed to the front base plate 101 via a thermally insulating block 106. An elongate thermally deformable support plate 16, for example a plate aluminum, is disposed horizontally in a longitudinal direction of the conveyor and comprises a central reference portion which is rigidly fixed to the bracket 105. The support plate 16 extends on either side of the central reference part and supports in the vicinity end of the brackets 107 (only one of which is shown in Figure 1) attached to the plate 16 and having at their upper part a horizontal wing bearing on a thermally insulating block 108 attached to the front base plate 101. The stem 107 is thus free to slide during longitudinal deformations of the support plate 16 under the effect of temperature variations. In this way, transverse deformation of the support plate 16 in the different temperature zones traversed by the support plate 16 is avoided, and the deformation that would be caused by the difference in expansion between the support plate 16 and the base plate 101 is avoided. .
Sur le côté opposé du convoyeur, le châssis com- porte un mat central 109 qui s'étend verticalement sous la plaque de base supérieure 103 et est rigidement fixé à celle-ci par l'intermédiaire d'un bloc thermiquement isolant 110. Une potence 111 analogue à la potence 105 est rigidement fixée au mat central 109 pour s'étendre en face de la potence 105. Une seconde plaque support 16 analogue à la plaque support 16 précédemment décrite, s'étend longitudinalement sur le côté du convoyeur et a une partie centrale de référence qui est rigidement fixée à la potence 111. Au voisinage des extrémités de cette
plaque support et en regard des potences 107, le châssis du convoyeur comporte des potences 112 fixées à la plaque support 16 et comportant au voisinage de leur partie supérieure, une aile horizontale qui prend appui sur un bloc 113 porté par un mat 114 fixé à la plaque de base supérieure 103 par l'intermédiaire d'un bloc thermique- ment isolant 115. Comme pour la plaque support 16 associée à la potence 105, la plaque support 16 associée à la potence 111 est donc fixée dans sa partie centrale de ré- férence et est libre de se déformer longitudinalement en dehors de la partie de référence. La plaque support 16 ne subit donc aucune déformation transversale lorsqu'elle traverse les zones du convoyeur à des températures différentes et quelle que soit la différence de température entre la plaque support 16 et la plaque supérieure 103.On the opposite side of the conveyor, the frame comprises a central mat 109 which extends vertically under the upper base plate 103 and is rigidly secured thereto by means of a thermally insulating block 110. 111 similar to the stem 105 is rigidly fixed to the central mat 109 to extend in front of the bracket 105. A second support plate 16 similar to the support plate 16 described above, extends longitudinally on the side of the conveyor and has a central reference part which is rigidly fixed to the bracket 111. In the vicinity of the ends of this support plate and facing the brackets 107, the chassis of the conveyor comprises brackets 112 attached to the support plate 16 and having in the vicinity of their upper part, a horizontal wing which bears on a block 113 carried by a mat 114 attached to the upper base plate 103 via a thermally insulating block 115. As for the support plate 16 associated with the bracket 105, the support plate 16 associated with the bracket 111 is thus fixed in its central part of the frame. and is free to deform longitudinally outside the reference part. The support plate 16 therefore undergoes no transverse deformation as it passes through the conveyor zones at different temperatures and regardless of the temperature difference between the support plate 16 and the upper plate 103.
En référence à la figure 2, celle-ci illustre une structure de base du convoyeur selon l'invention de façon extrêmement schématique et pour une meilleure compréhension ces différents éléments ont été représentés à des dimensions et selon des distances sans rapport avec la réalité.With reference to FIG. 2, this illustrates a basic structure of the conveyor according to the invention in an extremely schematic manner and for a better understanding these different elements have been represented in dimensions and distances unrelated to reality.
Selon cette illustration très schématique, les potences 107 et 112 sont reliées par paires par des poutres transversales 2 sur lesquelles sont montées une paire de boîtiers 3 qui sont fixés dans une position déterminée sur les poutres transversales 2 et une paire de boîtiers mobiles 4 qui sont montés pour coulisser sur les poutres transversales 2. La position de chaque boîtier mobile 4 est réglée par une vis sans fin 5 ayant une ex- trémité fixée à un mat 114 pour tourner librement par rapport a celui-ci et coopérant avec un écrou du boîtier correspondant 4 et entraînée en rotation par un moteur 6 porté par la plaque de base frontale 101 (figure 1) . Les boîtiers fixes 3 sont simplement traversés par les vis
sans fin 5 sans interaction entre les vis sans fin et les boîtiers 3. Afin de ne pas interférer avec les vis sans fin 5 lors des variations de longueur des plaques supports 16, les potences 107 et 112 comportent des lumières oblongues pour le passage des vis 5.According to this very schematic illustration, the brackets 107 and 112 are connected in pairs by transverse beams 2 on which are mounted a pair of housings 3 which are fixed in a specific position on the transverse beams 2 and a pair of mobile housings 4 which are The position of each mobile housing 4 is adjusted by a worm 5 having an end attached to a mat 114 to rotate freely therewith and cooperating with a housing nut. corresponding 4 and driven in rotation by a motor 6 carried by the front base plate 101 (Figure 1). The fixed housings 3 are simply crossed by the screws without end 5 without interaction between the worm and the housings 3. In order not to interfere with the worm 5 during the length variations of the support plates 16, the brackets 107 and 112 comprise oblong slots for the passage of the screws 5.
Chaque paire de boîtiers porte un rail fixe 7 qui est fixé à la partie supérieure des boîtiers correspondants. Chaque rail fixe 7 comporte des fenêtres 8 pour permettre un passage et un mouvement de débattement de traverses 9 portant des rails mobiles 10. Les extrémités des traverses 9 sont fixées à des longerons latéraux 11. Les rails mobiles 10 associés aux boîtiers mobiles 4 sont montés sur les traverses 9 avec un jeu suffisant pour permettre un déplacement latéral sans frottement des rails mobiles 10 lors du déplacement latéral des boîtiers 4. Les rails supports mobiles 10 sont de préférence montés à l'extérieur des rails fixes 7 par rapport à un axe longitudinal du convoyeur.Each pair of housings carries a fixed rail 7 which is fixed to the upper part of the corresponding housings. Each fixed rail 7 has windows 8 to allow a passage and a movement movement of sleepers 9 carrying movable rails 10. The ends of the crosspieces 9 are fixed to side rails 11. The movable rails 10 associated with the mobile housings 4 are mounted on the sleepers 9 with sufficient clearance to allow frictionless lateral displacement of the movable rails 10 during the lateral displacement of the housings 4. The movable support rails 10 are preferably mounted outside the fixed rails 7 with respect to a longitudinal axis of the conveyor.
Les longerons latéraux 11 sont montés par 1 ' in- termédiaire de joncs anti-friction 13 pour coulisser sur des profilés de levage 12. Les longerons latéraux 11 sont déplacés par des organes de coulissement non représentés sur la figure 2 et simplement symbolisés par des flèches doubles horizontales sur cette figure. Les profilés de levage 12 sont portés par des plaques de levage 14 associées au châssis du convoyeur par des organes de levage non représentés sur la figure 2 et simplement symbolisés par des flèches verticales doubles sur cette figure.The side rails 11 are mounted by means of anti-friction rods 13 for sliding on lifting profiles 12. The side rails 11 are moved by sliding members not shown in FIG. 2 and simply symbolized by arrows double horizontal on this figure. The lifting profiles 12 are carried by lifting plates 14 associated with the chassis of the conveyor by lifting members not shown in Figure 2 and simply symbolized by double vertical arrows in this figure.
La figure 3 illustre de façon partielle un mode de réalisation de l'invention. Sur cette figure les éléments déjà décrits sont illustrés avec la même référence numérique, des références numériques supplémentaires étant attribuées aux éléments non représentés sur la figure 2.
En particulier, cette figure illustre, en relation avec une potence 112, un organe de levage comprenant un disque excentrique 15 porté par la plaque support 16. Une cage d'excentrique 17 est supportée par le disque ex- centrique 15 et est fixée à sa partie inférieure à la plaque de levage 14 correspondante. Le convoyeur comporte deux organes de levage sur chaque côté et les disques excentriques 15 sont commandés de façon simultanée comme illustré par la figure 3 par un embiellage 18 associé à un axe 19 relié à un moteur 39 porté par la plaque de base frontale 101 (figure 1) .Figure 3 partially illustrates an embodiment of the invention. In this figure the elements already described are illustrated with the same reference numeral, additional numerals are assigned to the elements not shown in Figure 2. In particular, this figure illustrates, in relation to a bracket 112, a lifting member comprising an eccentric disk 15 carried by the support plate 16. An eccentric cage 17 is supported by the eccentric disk 15 and is fixed to its lower part to the corresponding lifting plate 14. The conveyor has two lifting members on each side and the eccentric discs 15 are controlled simultaneously as illustrated in FIG. 3 by a linkage 18 associated with an axis 19 connected to a motor 39 carried by the front base plate 101 (FIG. 1).
Comme illustré par la figure 3, le mouvement selon une direction verticale seulement des plaques de levage 14 est obtenu au moyen de plaques de guidage 20 por- tées par les plaques supports 16 et comprenant une lumière verticale 21 dans laquelle est engagé un ergot 22 porté par la plaque de levage 14 correspondante.As illustrated in FIG. 3, the movement in a vertical direction only of the lifting plates 14 is obtained by means of guide plates 20 carried by the support plates 16 and comprising a vertical light 21 in which is engaged an ergot 22 worn. by the corresponding lifting plate 14.
Comme illustré par la figure 5, les organes de coulissement selon l'invention sont portés par les poten- ces 105 et 111. Dans l'exemple illustré, la potence 111 supporte un arbre cannelé 24 entraîné en rotation par un moteur 25 porté par la plaque de base frontale 101. L'axe 24 porte un pignon 26 sur lequel une chaîne 27 forme une boucle maintenant la chaîne 27 appliquée sur le pignon 26. De part et d'autre du pignon 26 la chaîne 27 s'étend sensiblement verticalement et est renvoyée horizontalement en passant sur des poulies de renvoi 28 montées pour tourner librement sur la potence 111. Les extrémités de la chaîne 27 sont fixées en deux points espacés d'un lon- geron de coulissement latéral 11 au moyen de brides 29.As illustrated in FIG. 5, the sliding members according to the invention are carried by the potentials 105 and 111. In the example illustrated, the bracket 111 supports a splined shaft 24 rotated by a motor 25 carried by the front plate 101. The axis 24 carries a pinion 26 on which a chain 27 forms a loop holding the chain 27 applied to the pinion 26. On either side of the pinion 26 the chain 27 extends substantially vertically and The ends of the chain 27 are fixed at two points spaced apart from a lateral sliding lenght 11 by means of flanges 29.
De préférence comme illustré sur la figure 5, l'arbre d'entraînement 24 traverse le convoyeur et sert à entraîner un pignon 26 d'un organe de coulissement identique porté par la potence 105 sur le côté opposé du con-
voyeur. Les deux organes de coulissement sont ainsi entraînés en synchronisme. Les deux organes de coulissement sont de préférence montés à mi-distance des extrémités du convoyeur . Ainsi que cela est illustré par des flèches épaisses doubles sur la figure 5, les mouvements de levage des longerons de coulissement sont possibles sans blocage des organes de coulissement en raison d'un pivotement des brins d'extrémité de la chaîne 27 autour des poulies de renvoi 28.Preferably, as illustrated in FIG. 5, the drive shaft 24 passes through the conveyor and serves to drive a pinion 26 of an identical sliding member carried by the bracket 105 on the opposite side of the conveyor. voyeur. The two sliding members are thus driven in synchronism. The two sliding members are preferably mounted at mid-distance from the ends of the conveyor. As is illustrated by double thick arrows in FIG. 5, the lifting movements of the sliding rails are possible without blocking of the sliding members due to a pivoting of the end strands of the chain 27 around the pulleys. reference 28.
Pour permettre un débattement latéral dans les deux sens du rail mobile 10 associé à un boîtier mobile 4, le rail fixe 7, fixé aux boîtiers 4, est de préférence associé à une joue 30 (voir figure 5) reliée au rail fixe 7 par des entretoises 31 de façon à prendre le rail mobile 10 en sandwich sans gêner les mouvements de celui-ci .To allow a lateral movement in both directions of the movable rail 10 associated with a mobile housing 4, the fixed rail 7, fixed to the housings 4, is preferably associated with a cheek 30 (see FIG. 5) connected to the fixed rail 7 by means of spacers 31 so as to take the movable rail 10 sandwich without hindering the movements thereof.
En référence aux figures 3 et 6, le convoyeur selon l'invention dans son mode de réalisation préféré com- porte des dispositions minimisant le transfert thermique par conduction longitudinale des rails et par contact entre les rails supports et les cartes transportées par le convoyeur. A cet effet, les rails fixes sont de préférence équipés de lames supports minces 32 fixées aux rails supports fixes pour s'étendre en saillie d'un bord supérieur des rails. De même, les rails mobiles 10 comportent des lames supports minces 33 fixées aux rails supports mobiles 10 pour s'étendre en saillie d'un bord supérieur des rails. Les lames supports 33 comportent de préférence une rampe de guidage 37 et sont équipées d'une barrette de levage 38 en saillie du côté de la rampe de guidage 37. De préférence pour minimiser encore le transfert par conduction, les lames supports 32, 33 comportent des échancrures 34 qui s'étendent entre les points de
fixation 35 des lames supports sur les rails supports.With reference to FIGS. 3 and 6, the conveyor according to the invention in its preferred embodiment comprises provisions that minimize heat transfer by longitudinal conduction of the rails and by contact between the support rails and the boards conveyed by the conveyor. For this purpose, the fixed rails are preferably equipped with thin support strips 32 fixed to the fixed support rails to extend projecting from an upper edge of the rails. Similarly, the movable rails 10 comprise thin support blades 33 fixed to the movable support rails 10 to extend projecting from an upper edge of the rails. The support blades 33 preferably comprise a guide ramp 37 and are equipped with a lifting bar 38 projecting from the side of the guide ramp 37. Preferably to further minimize transfer by conduction, the support blades 32, 33 comprise notches 34 that extend between the points of fixing 35 of the support blades on the support rails.
De plus, afin de minimiser la conduction thermique longitudinale dans les lames supports, celles-ci sont de préférence divisées en segments séparés par un inter- valle 36 (figure 3) correspondant à la limite entre deux chambres à des températures différentes.In addition, in order to minimize longitudinal thermal conduction in the support strips, these are preferably divided into segments separated by an interval 36 (Fig. 3) corresponding to the boundary between two chambers at different temperatures.
Dans une position d'arrêt, les cartes électroniques sont en appui sur le bord supérieur des lames supports minces 32. A partir de cette position les excentri- ques 15 sont manœuvrées pour soulever les profilés de levage 12 qui entraînent les traverses 9 vers le haut et par voie de conséquence amènent les barrettes de levage 38 en contact avec la face inférieure de la carte, la rampe de guidage 37 de la lame 33 assurant simultanément un positionnement latéral correct de la carte. Pour une position haute des organes de levage, la carte électronique est ainsi maintenue au-dessus du bord supérieur des lames supports 32 et une manœuvre des organes de coulis- sement provoque un déplacement longitudinal de la carte électronique sans frottement. Après arrêt du coulisse- ment, les organes de levage sont manœuvres vers le bas pour reposer la carte électronique sur le bord supérieur des lames minces 32, et les organes de coulissement sont manœuvres pour ramener les rails supports mobiles à leur position de départ.In a stop position, the electronic boards bear on the upper edge of the thin support blades 32. From this position the eccentric 15 are operated to lift the lifting profiles 12 which cause the sleepers 9 upwardly. and consequently bring the lifting bars 38 into contact with the underside of the card, the guide ramp 37 of the blade 33 simultaneously ensuring correct lateral positioning of the card. For a high position of the lifting members, the electronic card is thus maintained above the upper edge of the support blades 32 and a maneuvering of the sliding members causes a longitudinal displacement of the electronic card without friction. After stopping the slide, the lifting members are maneuvered down to rest the electronic board on the upper edge of the thin blades 32, and the sliding members are maneuvering to return the movable support rails to their starting position.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications. En particulier, bien que l'invention ait été illustrée avec deux paires de rails supports seulement, on peut prévoir une troisième paire de rails à mi-distance des paires de rails latérales afin d'éviter un flambage des cartes électroniques transportées par le convoyeur.
On peut également augmenter le nombre de paires de rails supports afin d'assurer simultanément le con- voyage de plusieurs lignes de cartes en parallèle.Of course, the invention is not limited to the embodiment described and variants may be provided without departing from the scope of the invention as defined by the claims. In particular, although the invention has been illustrated with only two pairs of support rails, a third pair of rails may be provided mid-way between the pairs of side rails to avoid buckling of the electronic boards conveyed by the conveyor. The number of pairs of support rails can also be increased so that several lines of cards can be simultaneously run in parallel.
De même, le convoyeur selon l'invention peut être réalisé avec différents organes de levage et différents organes de coulissement montés sur les côtés du châssis pour réaliser un levage des longerons de coulissement tout en permettant des variations de dilatation de ces longerons sans nuire à leur coulissement et sans nuire au parallélisme des rails supports de cartes.Similarly, the conveyor according to the invention can be made with different lifting members and different sliding members mounted on the sides of the frame for lifting the sliding rails while allowing variations in expansion of these side members without harming their sliding and without harming the parallelism of the rails card holders.
Bien que les rails supports aient été illustrés sous forme de plaques, ils peuvent être réalisés sous forme d'éléments tubulaires.Although the support rails have been illustrated in the form of plates, they can be made in the form of tubular elements.
Bien que les lames supports minces aient été il- lustrées avec des échancrures du côté du rail support, les échancrures peuvent être réalisées du côté du bord libre ou simultanément sur les deux côtés des lames supports.Although the thin support strips have been illustrated with indentations on the side of the support rail, the notches can be made on the free edge side or simultaneously on both sides of the support strips.
Bien que 1 ' invention ait été illustrée avec des éléments de châssis thermiquement déformables sous forme de plaques supports 16 fixées aux potences 105 et 111 dans une zone centrale des plaques supports, ces éléments peuvent avoir toute forme appropriée et être fixés au cadre de référence par une partie de référence quelconque, par exemple une extrémité, le reste de la plaque support restant libre de s'allonger afin d'éviter les déformations qui résulteraient d'une dilatation différentielle entre les plaques supports 16 et des parties plus froides du châssis et qui risqueraient de provoquer une déviation des articles transportés lors des transferts successifs.
Although the invention has been illustrated with thermally deformable frame members in the form of support plates 16 attached to the brackets 105 and 111 in a central area of the support plates, these elements may have any suitable shape and be attached to the reference frame by any reference part, for example one end, the rest of the support plate remaining free to elongate to prevent deformation that would result from differential expansion between the support plates 16 and colder parts of the frame and which could lead to a diversion of items carried during successive transfers.
