Description

Système de convoyage et installation de moulage par soufflage de récipients Conveying system and blow molding installation for containers
L'invention se rapporte au domaine des systèmes de convoyage d'entités discrètes, c'est-à-dire de convoyage d'éléments individuels.The invention relates to the field of systems for conveying discrete entities, that is to say for conveying individual elements.
L'invention sera plus particulièrement décrite dans le cadre de son application à une installation de soufflage de récipients dans laquelle le récipient est obtenu par soufflage d'une préforme précédemment réalisée par injection.The invention will be more particularly described in the context of its application to a container blowing installation in which the container is obtained by blowing a preform previously produced by injection.
Toutefois, l'invention trouvera application dans tout système de convoyage dans lequel on veut regrouper en une seule ligne et à un pas déterminé des entités provenant de plusieurs « sources ».However, the invention will find application in any conveying system in which it is desired to group together in a single line and at a determined step entities coming from several "sources".
Un tel regroupement se trouve par exemple nécessaire lorsque, dans une installation en ligne, plusieurs machines de faible cadence sont utilisées pour effectuer une même étape, en parallèle, les entités étant ensuite toutes traitées, pour une seconde étape, par une machine à haute cadence.Such a grouping is for example necessary when, in an online installation, several low-speed machines are used to perform the same step, in parallel, the entities then being all processed, for a second step, by a high-speed machine .
L'exemple qui sera développé est celui de l'alimentation d'un four de conditionnement thermique de préformes. Un tel four comporte généralement une chaîne ou une couronne de convoyage qui transporte les préformes devant des lampes à infrarouge afin de les porter à une température à laquelle le matériau thermoplastique devient déformable pour l'opération ultérieure de soufflage. Le four est généralement alimenté en préformes par une unité d'alimentation unique. Cette unité d'alimentation comporte généralement un bac dans lequel les préformes sont stockées en vrac, un ascenseur à tapis roulant incliné, un démêleur, et un rail d'alimentation incliné au bas duquel les préformes orientées verticalement sont accumulées pour former un stock tampon. Au bas de ce rail, un portillon automatique laisse passer à intervalles réguliers une préforme qui est alors prise en charge par une roue à encoches.The example that will be developed is that of supplying a preform thermal conditioning furnace. Such an oven generally comprises a conveyor chain or crown which transports the preforms in front of infrared lamps in order to bring them to a temperature at which the thermoplastic material becomes deformable for the subsequent blowing operation. The furnace is generally supplied with preforms by a single supply unit. This feed unit generally comprises a bin in which the preforms are stored in bulk, an inclined conveyor lift, a untangler, and an inclined feed rail at the bottom of which the vertically oriented preforms are accumulated to form a buffer stock. At the bottom of this rail, an automatic gate allows a preform to pass at regular intervals which is then supported by a notched wheel.
De telles unités d'alimentation présentent l'inconvénient d'un manque de fiabilité à haute cadence, notamment du fait de l'opération de démêlage qui est très délicate. Aussi , pour un bon fonctionnement de l'installation de souff lage, on propose ici d'alimenter l'installation par deux unités d'alimentation qui travaillent en parallèle. Chaque unité d'alimentation n'a ainsi plus q u'à assurer la moitié de la cadence de l'installation de soufflage. Cependant, il s'avère alors nécessaire de prévoi r u n système de convoyage qui regroupe les préformes fou rnies par les deux un ités d'alimentation de telle sorte q ue, au n iveau du fou r, tout se passe comme si l'installation était munie d'u ne uniq ue unité d'alimentation .Such power supply units have the drawback of a lack of reliability at high speed, in particular due to the disentangling operation which is very delicate. Also, for proper operation of the blowing installation, it is proposed here to supply the installation with two supply units which work in parallel. Each supply unit thus only has to maintain half the speed of the blowing installation. However, it then becomes necessary to provide a conveyor system which groups together the preforms supplied by the two supply lines so that, at the level of the supplier, everything takes place as if the installation were fitted with only one power supply unit.
Ce système doit être à la fois simple, fiable et de faible encombrement.This system must be simple, reliable and compact.

At the bottom of the rail, a gate (not shown), for example made in the form of a retractable finger, lets the preforms pass one by one so that they engage on a pitch wheel 26, 27 The pitch wheel is constituted here by a notched wheel Each feeding unit 1 6, 1 7, provided with its pitch wheel 26,27, is therefore capable of providing a series of preforms spaced according to a first step. Feed units of this type are for example used in the blowing installations marketed by the applicant.
Su r la figure 2 , on retrouve les deux roues de mise au pas 26, 27 des deux unités 1 6 , 1 7, ainsi que l'extrémité inférieure des deux rails d'alimentation 24 associés par lesquels arrivent respectivement les deux séries 1 1 , 1 3 de préformes.In Figure 2, there are the two pitch wheels 26, 27 of the two units 1 6, 1 7, as well as the lower end of the two supply rails 24 associated by which the two series 1 1 arrive respectively. , 1 3 of preforms.
De manière connue, les roues de mise au pas 26, 27 sont constituées chacu ne d'un disque 28 q u i est muni à sa périphérie d'encoches 30 sensiblement semi-circulaires et espacées régulièrement. Les disques 28 sont entraînés en rotation de manière continue autou r de leu rs axes respectifs A1 et A2. Le portillon (non représenté) du système d'al imentation est commande pour q ue, lorsqu'une encoche 30 se trouve en face de l'extrémité du rail 24, une préforme soit libérée et vienne s'engager dans l'encoche q u i l'entraîne alors en rotation Un guide circulaire extérieu r 32, 34 permet d'éviter que la préforme ne s'échappe de l'encoche 30 dont la profondeu r radiale est généralement sensiblement égale à la moitié du diamètre de la préforme seulement. A parti r de leur prise en charge par les roues de mise au pas, les préformes sont toujou rs convoyées de manière individualisée, le transfert s'effectuant toujou rs en prise, c'est-à-di re sans que la preforme ne soit relâchée. I l est en effet important que la préforme conserve son orientation , notamment pour pouvoi r être prise en charge dans le four.In known manner, the pitching wheels 26, 27 each consist of a disc 28 which is provided at its periphery with substantially semi-circular notches 30 and regularly spaced. The discs 28 are rotated continuously around their respective axes A1 and A2. The door (not shown) of the supply system is controlled so that when a notch 30 is opposite the end of the rail 24, a preform is released and engages in the notch which l 'then drives in rotation An external circular guide r 32, 34 makes it possible to prevent the preform from escaping from the notch 30, the radial depth of which is generally substantially equal to half the diameter of the preform only. From their taking over by the pitching wheels, the preforms are always conveyed individually, the transfer always taking place, that is to say without the preform being released. It is indeed important that the preform retains its orientation, especially so that it can be taken care of in the oven.
Conformément aux enseignements de l'invention , les deux roues de mise au pas 26, 27, q ui sont identiques, sont destinées à alimenter une même roue de reg roupement 36. A la sortie de cette roue de reg roupement, les deux séries 1 1 , 1 3 de préformes fournies par les unités d'alimentation sont reg roupées en une uniq ue suite de préformes espacées selon u n nouveau pas , de préférence au pas du système de convoyage des préformes dans le fou r 1 4. La roue de reg roupement 36 est elle aussi constituée d'un disque q ui est entraîné en rotation autour de son axe A3 en synch ronisme avec les deux roues de mise au pas 26 , 27 Selon l'invention, la roue de regroupement comporte des encoches qui sont agencées à la périphérie du disque et q ui sont réparties en autant de séries q u'il y a d'unités d'alimentation . Les séries d'encoches diffèrent par la profondeur radiale de leurs encoches, lesquelles sont orientées radialement par rapport à l'axe A3 et sont ouverts vers l'extérieur.In accordance with the teachings of the invention, the two pitching wheels 26, 27, which are identical, are intended to supply the same registration wheel 36. At the output of this registration wheel, the two series 1 1, 1 3 of preforms supplied by the feed units are rouped into a single sequence of preforms spaced at a new step, preferably in step with the system for conveying the preforms in the feeder 1 4. The reg wheel roupement 36 also consists of a disc q ui which is rotated about its axis A3 in synchronism with the two pitch wheels 26, 27 According to the invention, the grouping wheel has notches which are arranged at the periphery of the disc and which are distributed in as many series as there are supply units. The series of notches differ in the radial depth of their notches, which are oriented radially with respect to the axis A3 and are open towards the outside.
Dans l'exemple illustré, la roue de reg roupement 36 comporte donc deux séries d'encoches 38, 40. Les encoches 38 de la première série présentent une profondeur radiale relativement importante, par exemple de l'ordre de deux fois le diamètre des préformes. Les encoches 40 de la seconde série sont sensiblement semi-circulaires et présentent une profondeur de l'ordre de la moitié du diamètre de la préforme.In the example illustrated, the registration wheel 36 therefore comprises two series of notches 38, 40. The notches 38 of the first series have a relatively large radial depth, for example of the order of twice the diameter of the preforms . The notches 40 of the second series are substantially semi-circular and have a depth of the order of half the diameter of the preform.
Les encoches des deux séries sont intercalées en ce sens q ue, le long de la périphérie du disque, on retrouve alternativement une encoche de l'une des séries puis une encoche de l'autre série. Les encoches 38, 40 de la roue de reg roupement sont espacées circonférentiellement d'un pas qui est moitié de celui séparant deux encoches 30 des roues de mise au pas 26, 27. Les deux ro ues de m ise au pas 26 , 27 sont disposées tangentiellement à la roue de reg roupement 36 et elles sont synchronisées avec celle-ci pour que, lorsq u'une encoche 30 se trouve au niveau du point de tangence, elle se retrouve juste en regard d'une encoche 38 , 40 de la roue de reg roupement. Selon l'invention , les encoches 30 d'une roue de mise au pas donnée se trouveront obligatoi rement en regard d'une encoche d' u ne série donnée de la roue de regroupement 36. I nversement, les deux points de tangence de la roue de regroupement 36 sont choisis pour que les encoches 38, 40 d'une même série ne puissent se retrouver en regard q u'avec les encoches de l'une des deux roues de mise au pas Le chargement des préformes dans les encoches de la roue de reg roupement se fait radialement, de l'extérieu r vers l'intérieu r Même au moment du passage de la roue de mise au pas à la roue de reg roupement, la préforme continue d'être parfaitement maintenue et i ndexée, ce qui permet de conserver exactement le pas entre deux préformes d'une même série Le système de guidage selon l'invention comporte par ailleu rs des glissières q ui permettent de déterminer la position radiale des préformes q ui sont prises dans les encoches de la roue de regroupement. Ces glissières sont par exemple réalisées sous la forme d'éléments de plaq ues f ixes qui sont agencés dans un plan axiaiement décale par rapport au plan des disq ues des roues, et dont un bord forme une glissière sur laquelle les préformes prennent appui radialement et glissent lorsq u'elles sont entraînées en rotation par les roues.The notches of the two series are interspersed in this sense that, along the periphery of the disc, there is alternately a notch from one of the series then a notch from the other series. The notches 38, 40 of the grouping wheel are circumferentially spaced apart by a pitch which is half that separating two notches 30 from the pitching wheels 26, 27. The two metering wheels at pitch 26, 27 are arranged tangentially to the registration wheel 36 and they are synchronized with the latter so that, when a notch 30 is at the point of tangency, it is found just opposite a notch 38, 40 of the reg roupement wheel. According to the invention, the notches 30 of a given pitch wheel will necessarily be found opposite a notch of a given series of the grouping wheel 36. Conversely, the two tangent points of the grouping wheel 36 are chosen so that the notches 38, 40 of the same series cannot be found facing each other with the notches of one of the two pitching wheels Loading preforms in the notches of the reg rouping wheel are made radially, from the exterior to the interior r Even at the time of the passage from the pitching wheel to the reg rouping wheel, the preform continues to be perfectly maintained and indexed, which makes it possible to exactly keep the pitch between two preforms of the same series The guide system according to the invention also comprises slides which enable the radial position of the preforms which are taken to be determined in the notches on the grouping wheel. These slides are for example made in the form of fixed plate elements which are arranged in a plane axially offset from the plane of the wheel disks, and one edge of which forms a slide on which the preforms bear radially and slide when rotated by the wheels.
Sur la figure 2, on peut voir que la première roue de mise au pas 26, dont le point de tangence est le plus éloigné du point de tangence de la roue de reg roupement 36 avec une roue de sortie 42, est destinée à amener des préformes 1 1 dans les encoches profondes 38 de la roue de regroupement. Le chargement des préformes 1 1 de cette première série est donc effectué en ce point de tangence, grâce a une glissière interne 44 et à une première glissière externe 46. La glissière externe 46 oblige les préformes à s'échapper des encoches 30 de la première roue de chargement 26. Ensuite, les deux gl issières 44, 46 coopèrent avec les préformes de cette première série pour les pousser radialement vers l'intérieur au fond des encoches 38, au f ur et à mesu re de leur progression angulaire autour de l'axe A3. On peut voi r q ue, sous l'action des glissières 44, 46, les préformesIn FIG. 2, it can be seen that the first pitch wheel 26, the point of tangency of which is furthest from the point of tangency of the registration wheel 36 with an output wheel 42, is intended to bring preforms 1 1 in the deep notches 38 of the grouping wheel. The loading of the preforms 1 1 of this first series is therefore carried out at this point of tangency, thanks to an internal slide 44 and to a first external slide 46. The external slide 46 forces the preforms to escape from the notches 30 of the first loading wheel 26. Next, the two slides 44, 46 cooperate with the preforms of this first series to push them radially inwards at the bottom of the notches 38, in the measure and as their angular progression around the 'A3 axis. We can see that, under the action of the slides 44, 46, the preforms
1 1 de cette première série ont atteint le fond de l'encoche 38 correspondante avant q u'elles n'aient atteint angulairement le point de tangence de la seconde roue de mise au pas 27 avec la roue de reg roupement 36. Dans l'exemple illustré, la glissière extérieu re 46 correspondant à la première roue de mise au pas 26 et le guide 34 de la seconde roue de mise au pas 27 sont formés par deux bords d'un même élément de plaq ue q ui présente ainsi une pointe effilée 48 dél imitée par les extrémités respectives du guide 34 et de la première glissière extérieure 46. L'extrémité de cette pointe 48 est située angulai rement j uste avant le point de chargement des préformes de la seconde série, ce point correspondant au point de tangence de la seconde roue de mise au pas 27 avec la roue de regroupement 36. Cette pointe 48 s'étend radialement par rapport à l'axe A3 entre le fond des encoches 38 de la première série et celui des encoches 40 de la seconde série. Bien entendu , la pointe 48 ne doit pas fai re obstacle à une préforme 1 1 de la première série qui serait emmenée par une encoche 38 de la roue de regroupement 36.1 1 of this first series have reached the bottom of the corresponding notch 38 before they have angularly reached the point of tangency of the second pitch wheel 27 with the registration wheel 36. In the illustrated example, the outer slide 46 corresponding to the first pitch wheel 26 and the guide 34 of the second wheel pitch 27 are formed by two edges of the same plate element which thus has a tapered tip 48 delimited by the respective ends of the guide 34 and of the first outer slide 46. The end of this tip 48 is located angularly just before the loading point of the preforms of the second series, this point corresponding to the point of tangency of the second pitch wheel 27 with the grouping wheel 36. This point 48 extends radially with respect to the axis A3 between the bottom of the notches 38 of the first series and that of the notches 40 of the second series. Of course, the tip 48 must not be an obstacle to a preform 11 of the first series which would be taken up by a notch 38 in the grouping wheel 36.
G râce à l'invention , on voit q ue les premières préformes 1 1 sont ainsi dégagées radialement vers l'intérieu r pou r ne pas interférer avec le guide 34 de la seconde roue de mise au pas 27. Une seconde glissière extérieure 50 s'étend selon un arc de cercle autour de l'axe A3 entre le point de chargement des préformes 1 3 de la seconde série et le point de déchargement de toutes les préformes qui correspond au point de tangence de la roue de regroupement 36 avec la roue de sortie 42. Cette seconde glissière 50 a pour première fonction de mainteni r les préformes de la seconde série en appui au fond de leurs encoches 40 , sans q uoi ces préformes ne pourraient teni r su r la roue 36.Thanks to the invention, it can be seen that the first preforms 1 1 are thus released radially inwards for not interfering with the guide 34 of the second pitch wheel 27. A second external slide 50 s 'extends in an arc around the axis A3 between the loading point of the preforms 1 3 of the second series and the unloading point of all the preforms which corresponds to the point of tangency of the regrouping wheel 36 with the wheel 42. This second slide 50 has the primary function of maintaining the preforms of the second series in abutment at the bottom of their notches 40, without these preforms being able to hold on to the wheel 36.
Contrairement à la première glissière extérieure 46, la glissière intérieu re 44 se prolonge selon un second tronçon entre le point de chargement de la seconde série de préformes 1 3 et le point de déchargement. Le profil de ce second tronçon est tel q u'il repousse les préformes 1 1 de la première série radialement vers l'extérieur une fois q u'elles ont f ranchi le point de chargement de celles de la seconde série. En effet, au-delà de ce point, les préformes 1 1 de la première série ne risquent plus d' interférer avec un g uide de la seconde roue de mise au pas. Le second tronçon de la glissière intérieure permet ainsi de ramener radialement les préfo rmes 1 1 de la première série sur le même rayon q ue celles 1 3 de la seconde série.Unlike the first external slide 46, the internal slide 44 extends in a second section between the loading point of the second series of preforms 1 3 and the unloading point. The profile of this second section is such that it repels the preforms 1 1 of the first series radially outwards once they have cut the loading point from those of the second series. Indeed, beyond this point, the preforms 11 of the first series no longer risk interfering with a guide of the second pitch wheel. The second section of the inner slide thus makes it possible to bring the preforms 1 1 of the first series radially to the same radius as those 1 3 of the second series.
Ainsi , au niveau du point de déchargement, les préformes 1 1 , 1 3 des deux séries se trouvent prises radialement entre la glissière intérieu re 44 et la seconde glissière extérieu re 50. Elles peuvent alors être prises en charge de manière conventionnelle par la roue de sortie 42. L'organe de regroupement ainsi proposé est donc parfaitement f iable car les entités qu' il transporte, par exemple les préformes, restent à chaque instant parfaitement indexées le long de leu r trajectoire du fait qu'elles restent prises dans des encoches. I l n'y a donc aucun risq ue de les voir s'emmêler ou de les voi r se bloq uer contre une partie de cet organe, contrairement à ce q u i peut se passer avec un mécanisme a aiguillage Elles conservent bien entendu leu r orientation verticale tout au long du trajet su r les roues de mise au pas et de regroupement.Thus, at the unloading point, the preforms 1 1, 1 3 of the two series are taken radially between the internal slide 44 and the second external slide 50. They can then be taken care of in a conventional manner by the wheel outlet 42. The grouping device thus proposed is therefore perfectly reliable since the entities which it carries, for example the preforms, remain at all times perfectly indexed along their trajectory due to the fact that they remain caught in notches. There is therefore no risk of seeing them become entangled or of seeing them block against a part of this organ, unlike what can happen with a switching mechanism. They of course retain their orientation. vertical along the path on the pitch and group wheels.
L'invention vient d'être décrite dans le cas où l' unité amont comporte des roues à encoches q ui assurent une mise au pas . Toutefois, on pou rrait aussi mettre en œuvre une roue de reg roupement selon l'invention en l'absence d' un système de mise au pas ou en utilisant un système différent Les entités pourraient ainsi être di rectement amenées à la roue de regroupement par des bras de transferts synch ronisés. The invention has just been described in the case where the upstream unit comprises notched wheels which ensure a pitch. However, one could also implement a grouping wheel according to the invention in the absence of a pitching system or by using a different system. The entities could thus be brought directly to the grouping wheel by synchronized transfer arms.
