Abstract

Raw plums fed into a receiving tank and washer (1) are conveyed by a platform elevator (2) to a cord-type sizing device which enables their distribution toward two tray-carrying chains (5A and 5B). The trays are stacked on carts carried by platform elevators (8A and 8B). Once they have been filled, the carts can be transported to a cooking oven (9).

Description

L'invention concerne le traitement des fruits verts, en particulier de prunes, auxquelles il est classique de faire subir une cuisson pour les transformer en pruneaux.The invention relates to the treatment of green fruits, in particular plums, to which it is conventional to undergo cooking in order to transform them into prunes.

Les installations connues jusqu'à présent font intervenir des opérateurs à divers niveaux. C'est le cas notamment pour la répartition, après tri (calibrage) des prunes vertes dans des claies, qui sont ensuite mises sur des chariots pour être transportées dans un four de cuisson.The installations known so far involve operators at various levels. This is the case in particular for the distribution, after sorting (sizing) of the green plums in racks, which are then put on trolleys to be transported in a baking oven.

Par ailleurs, le fait qu'il existe de nombreuses exploitations déjà équipées en claies et chariots, notamment, a pour conséquence qu'il est le plus souvent difficile de reprendre complètement les installations existantes, pour les automatiser, sans perdre le bénéfice des investissements déjà effectués.Furthermore, the fact that there are many operations already equipped with racks and trolleys, in particular, means that it is most often difficult to completely take over existing installations, to automate them, without losing the benefit of the investments already made. performed.

La présente invention vient apporter une solution à ce problème.The present invention provides a solution to this problem.

Pour cela, il est proposé une installation pour le traitement de fruits verts, en particulier de prunes, qui comporte, en combinaison :

  • - un bac récepteur de prunes vertes en vrac, avec des moyens de lavage et de pré-séchage de celles-ci,
  • - un tapis élévateur pour extraire les prunes vertes du bac,
  • - une calibreuse, alimentée en prunes vertes par le tapis élévateur, et placée en surplomb,
  • - au moins deux chaînes de transport de claies, passant sous la calibreuse en deux endroits différents, pour recevoir de celle-ci des prunes vertes de tailles différentes,
  • - au moins deux élévateurs à plateau, respectivement montés au bout des deux chaînes de transport de claies, pour permettre un empilement de claies sur des chariots, et
  • - des moyens pour transporter ces chariots dans un four de cuisson.
For this, an installation is proposed for the treatment of green fruits, in particular plums, which comprises, in combination:
  • - a receptacle for loose green plums, with means for washing and pre-drying them,
  • - a lifting belt to extract the green plums from the tank,
  • - a grader, fed with green plums by the lifting belt, and placed overhanging,
  • - at least two rack transport chains, passing under the grader in two different places, to receive from it green plums of different sizes,
  • at least two platform elevators, respectively mounted at the end of the two rack transport chains, to allow stacking of racks on trolleys, and
  • - Means for transporting these carts in a cooking oven.

Avec une telle installation, l'intervention de personnel se limite à la surveillance générale, à la dépose de nouvelles claies sur les chaînes de transport, et le cas échéant au transfert de chariot depuis l'élévateur jusqu'au four, ce transfert étant directement guidé par des rails.With such an installation, the intervention of personnel is limited to general surveillance, the removal of new racks on the transport chains, and if necessary the transfer of the trolley from the elevator to the oven, this transfer being directly guided by rails.

Selon un aspect de l'invention, la calibreuse comprend une série de cordes mobiles côte à côte en circuit fermé, l'écartement entre les cordes augmentant le long du trajet des fruits verts à partir de l'entrée de cette calibreuse.According to one aspect of the invention, the grader comprises a series of strings movable side by side in a closed circuit, the spacing between the strings increasing along the path of the green fruits from the entrance of this grader.

Pour sa part, il est avantageux que le tapis élévateur soit muni de moyens de rinçage.For its part, it is advantageous that the lifting belt is provided with rinsing means.

Selon un autre aspect, particulièrement important, de l'invention, chaque chaîne de transport comprend :

  • - des premiers moyens propres à entraîner des claies en file, pour qu'elles passent au droit de l'un des postes de sortie de la calibreuse,
  • - des seconds moyens propres à un entraînement accéléré d'une claie, munis de moyens de transfert de cette claie, en vue de son empilement sur un chariot porté par l'élévateur à plateau associé.
According to another, particularly important aspect of the invention, each transport chain comprises:
  • - the first means suitable for driving racks in a line, so that they pass to the right of one of the grader's exit stations,
  • - Second means specific to an accelerated drive of a rack, provided with means for transferring this rack, with a view to stacking it on a carriage carried by the elevator with associated tray.

Avantageusement, l'entraînement des claies est assuré par une première et une seconde chaîne sans fin à rouleau, respectivement implantées dans les premiers et seconds moyens d'entraînement, et entraînées à partir d'un même moteur à des vitesses linéaires différentes. Il est intéressant que ce moteur soit situé du côté aval des seconds moyens d'entraînement.Advantageously, the drive of the racks is ensured by a first and a second endless roller chain, respectively located in the first and second drive means, and driven from the same motor at different linear speeds. It is interesting that this motor is located on the downstream side of the second drive means.

De préférence, les moyens de transfert qui font partie des seconds moyens d'entraînement comprennent un organe poussoir pour assurer le transfert de la claie sur le chariot, en même temps qu'un bon empilement des claies les unes sur les autres sur ce même chariot.Preferably, the transfer means which are part of the second drive means comprise a pusher member for ensuring the transfer of the rack on the carriage, at the same time as a good stacking of the racks on one another on this same carriage .

Dans un mode de réalisation, les seconds moyens d'entraînement comprennent une troisième chaîne, dont la partie utile défile au-dessus de celle de la seconde chaîne, et cette troisième chaîne est entraînée par un moteur séparé, qui actionne également deux galets poussoirs placés chacun à l'extrémité d'un bras.In one embodiment, the second drive means comprise a third chain, the useful part of which scrolls above that of the second chain, and this third chain is driven by a separate motor, which also actuates two push rollers placed each at the end of an arm.

Par ailleurs, et dans un mode de réalisation particulier, les premiers et seconds moyens d'entraînement comportent des rouleaux et/ou galets alignés, propres à un support continu des claies par leurs montants latéraux.Furthermore, and in a particular embodiment, the first and second drive means comprise rollers and / or rollers aligned, suitable for continuous support of the racks by their lateral uprights.

D'autres caractéristiques et avantages de l'invention apparaîtront à l'examen de la description détaillée ci-après, et des dessins annexés, sur lesquels :

  • - la figure 1 est une vue générale schématique, en perspective, d'une installation selon l'invention;
  • - la figure 2 est une vue de côté des premiers et seconds moyens d'entraînement selon l'invention;
  • - les figures 2A, 2B et 2C sont des détails du dispositif de la figure 2; et
  • - les figures 3A et 3B sont respectivement une vue latérale et une vue de dessus de l'un des dispositifs élévateurs à plateau selon l'invention.
Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended drawings, in which:
  • - Figure 1 is a general schematic perspective view of an installation according to the invention;
  • - Figure 2 is a side view of the first and second drive means according to the invention;
  • - Figures 2A, 2B and 2C are details of the device of Figure 2; and
  • - Figures 3A and 3B are respectively a side view and a top view of one of the platform lifting devices according to the invention.

Il est clair que la présente invention fait intervenir à de nombreux égards les dispositions de différents éléments dans l'espace. Par ailleurs, les dessins annexés sont pour l'essentiel à l'échelle. En conséquence, ces dessins pourront non seulement servir à éclairer la description ci-après, mais aussi contribuer à la définition de l'invention, le cas échéant.It is clear that the present invention involves in many respects the arrangements of different elements in space. Furthermore, the accompanying drawings are essentially to scale. Consequently, these drawings could not only serve to clarify the description below, but also contribute to the definition of the invention, if necessary.

Sur la figure 1, l'installation selon l'invention commence dans le coin inférieur gauche par un bac récepteur de prunes vertes en vrac, référencé 1. Ce bac 1 est muni d'une alimentation en eau, ainsi que d'un trop-plein, de manière à pouvoir réaliser un lavage des prunes.In FIG. 1, the installation according to the invention begins in the lower left corner with a receptacle for loose green plums, referenced 1. This receptacle 1 is provided with a water supply, as well as an overflow full, so that plums can be washed.

Un tapis élévateur 2 part de l'intérieur de ce bac 1 pour remonter les prunes vertes et les délivrer à un plan incliné 29. Des lamelles sont naturellement solidaires de ce tapis pour faire monter les prunes. En cours de montée, une rampe 28 équipée de pulvérisateurs assure le rinçage des prunes. Le plan incliné 29 délivre les prunes vertes à une calibreuse désignée dans son ensemble par 3. Cette calibreuse comporte des cordes 30 montées en circuit fermé, et agencées de telle manière que leur écartement augmente le long du trajet des prunes. Sous la calibreuse sont prévus deux postes de sortie de prunes 38A et 38B, formant respectivement convergent au-dessus de chaînes de transport 5A et 58. L'écartement des cordes 30 augmente au fur et à mesure que les prunes avancent vers l'extrémité haute de la calibreuse 3. On assure ainsi, d'une manière très simple et efficace, que les prunes de taille inférieure à un seuil sont distribuées au niveau du poste de sortie 38A, tandis que les autres sont distribuées au niveau du poste de sortie 38B.A lifting belt 2 leaves from the interior of this tank 1 to raise the green plums and deliver them to a inclined plane 29. Slats are naturally attached to this carpet to raise the plums. During the climb, a ramp 28 equipped with sprayers rinses the plums. The inclined plane 29 delivers the green plums to a grading machine designated as a whole by 3. This grading machine has strings 30 mounted in a closed circuit, and arranged in such a way that their spacing increases along the path of the plums. Under the grader are provided two plum outlet stations 38A and 38B, forming respectively converging above transport chains 5A and 58. The spacing of the strings 30 increases as the plums advance towards the upper end grader 3. It is thus ensured, in a very simple and effective manner, that plums of size less than a threshold are distributed at the exit station 38A, while the others are distributed at the exit station 38B .

Chacune des chaînes 5A et 5B comporte de premiers moyens d'entraînement 50, suivis de seconds moyens d'entraînement 60, ces derniers assurant le transfert d'une claie vers l'un des élévateurs à plateau 8A et 8B, comme on le verra plus loin.Each of the chains 5A and 5B comprises first drive means 50, followed by second drive means 60, the latter ensuring the transfer of a rack to one of the platform elevators 8A and 8B, as will be seen more far.

Sur la chaîne 5B, on a représenté des claies en C1, C2, C3.On chain 5B, racks of C1, C2 and C3 have been shown.

Sur les élévateurs à plateau 8 sont placés des chariots (non représentés pour simplifier). Lorsqu'un chariot est plein, le plateau 85 qui le supporte est ramené en position basse, et un système de rails 90, 91 permet le transfert de ce chariot vers le four de cuisson 9. Le système de rails 90, 91 est commandé par deux alimentations différentes (non représentées), l'une étant appropriée à la cuisson des prunes de petit calibre et l'autre étant appropriée à la cuisson des prunes de grand calibre.Trolleys 8 are placed on carriages (not shown for simplicity). When a trolley is full, the tray 85 which supports it is returned to the low position, and a rail system 90, 91 allows the transfer of this trolley to the baking oven 9. The rail system 90, 91 is controlled by two different feeds (not shown), one being suitable for cooking small plums and the other being suitable for cooking large plums.

De façon générale, chaque élévateur à plateau 8 comporte une embase en forme générale de U, avec un fond 81 F, un bord gauche 81 G et un bord droit 81 D. Le fond 81 F supporte le montant 82 sur lequel se déplace le plateau 85.Generally, each platform elevator 8 has a base in the general shape of a U, with a bottom 81 F, a left edge 81 G and a right edge 81 D. The bottom 81 F supports the upright 82 on which the platform moves 85.

Il est maintenant fait référence à la figure 2. On omettra les suffixes A et B des références numériques, pour simplifier l'exposé.Reference is now made to FIG. 2. The suffixes A and B of the numerical references will be omitted, to simplify the description.

Une table est définie par des pieds 51-1, etc, reliés en partie basse par des barres 52-1, etc. Ces pieds supportent une structure dont on voit l'un des flasques latéraux 54, et qui soutient les galets d'extrémités 532 et 533, sur lesquels s'enroule une chaîne sans fin 53. Cette chaîne 53 est par exemple une chaîne "Sedis" type agricole, référence S45. Au droit du pied 51-2, on distingue le tendeur de chaîne 531.A table is defined by legs 51-1, etc., connected at the bottom by bars 52-1, etc. These feet support a structure of which one sees one of the lateral flanges 54, and which supports the end rollers 532 and 533, on which is wound an endless chain 53. This chain 53 is for example a "Sedis" chain agricultural type, reference S45. To the right of foot 51-2, there is the chain tensioner 531.

La partie supérieure de la chaîne, entre les galets 532 et 533, circule sur un guide rectiligne, du moins dans la zone où vont être entraînées les claies.The upper part of the chain, between the rollers 532 and 533, runs on a straight guide, at least in the area where the racks will be driven.

Une claie est illustrée schématiquement sur la figure 2D.A screen is illustrated schematically in Figure 2D.

Elle comprend un support plan classique 70, dont les bordures sont serrées entre des paires de montants latéraux 71 et des paires de montants d'extrémités 72. En outre, sensiblement au milieu de la claie, le plan 70 est supporté par une traverse inférieure 73, montée entre les parties basses des parties latérales 71, perpendiculairement à celles-ci.It comprises a conventional flat support 70, the edges of which are clamped between pairs of lateral uprights 71 and pairs of end uprights 72. In addition, substantially in the middle of the rack, the plane 70 is supported by a lower cross-member 73 , mounted between the lower parts of the lateral parts 71, perpendicular to the latter.

Au sein des premiers moyens d'entraînement 50, les parties basses des supports latéraux 71 reposent sur des rouleaux convenablement disposés le long du chemin de déplacement des claies C1, C2, C3.Within the first drive means 50, the lower parts of the lateral supports 71 rest on rollers suitably arranged along the path of movement of the racks C1, C2, C3.

Le tendeur de chaîne déjà mentionné est disposé de telle manière que les rouleaux de la chaîne viennent en prise douce sur les parties basses des montants d'extrémités 72, ainsi que de la traverse intermédiaire 73.The chain tensioner already mentioned is arranged in such a way that the chain rollers come into a soft grip on the lower parts of the end posts 72, as well as of the intermediate cross-member 73.

On assure ainsi un entraînement doux et régulier des différentes claies dans le sens de marche, qui va de la gauche vers la droite sur la figure 2. Mais cet entraînement n'est pas systématique, puisque si une claie se trouve retenue, le rouleau peut échapper par en dessous, et cesser d'entraîner l'ensemble des claies.This ensures a smooth and regular drive of the different racks in the direction of travel, which goes from left to right in Figure 2. But this training is not systematic, since if a rack is retained, the roller can escape from below, and stop dragging all the racks.

Au niveau intermédiaire des premiers moyens d'entraînement 50, la claie C2 se trouve au droit d'une goulotte oblique 39, terminant l'un des convergents ou trémies 38 de la figure 1.At the intermediate level of the first drive means 50, the rack C2 is located in line with an oblique chute 39, terminating one of the converging or hoppers 38 of FIG. 1.

L'un des rouleaux supportant les parties latérales 71 des claies apparaît en 59, à l'extrémité droite des premiers moyens d'entraînement 50.One of the rollers supporting the lateral parts 71 of the racks appears at 59, at the right end of the first drive means 50.

Sur le même arbre que le galet 533 qui renvoie la chaîne 53, est monté un pignon 534, coopérant par l'intermédiaire d'une chaîne sans fin 535 avec un pignon plus petit 634 des seconds moyens d'entraînement 60. Ce même pignon 634 est monté sur le même arbre qu'un galet 633, sur lequel s'enroule une seconde chaîne d'entraînement de claie, notée 63, et de même nature que la chaîne 53. Cette chaîne 63 vient à son tour sur un autre galet 632, monté sur le même arbre qu'une poulie 636 entraînée par une courroie 637 arrivant sur la poulie 638 d'un moteur 639 monté sur un support 640. Ce support 640 est solidaire de l'un 61-2 des pieds 61 des seconds moyens d'entraînement 60, où l'on observe également une traverse inférieure 62-1.On the same shaft as the roller 533 which returns the chain 53, is mounted a pinion 534, cooperating via an endless chain 535 with a smaller pinion 634 of the second drive means 60. This same pinion 634 is mounted on the same shaft as a roller 633, on which is wound a second rack drive chain, denoted 63, and of the same nature as the chain 53. This chain 63 in turn comes on another roller 632 , mounted on the same shaft as a pulley 636 driven by a belt 637 arriving on the pulley 638 of a motor 639 mounted on a support 640. This support 640 is integral with one 61-2 of the feet 61 of the second means drive 60, where there is also a lower cross 62-1.

La seconde chaîne d'entraînement de claie 63 possède elle aussi son tendeur 631, ainsi qu'un guidage en partie supérieure, pour l'amener sensiblement en alignement à ce niveau sur la partie supérieure de la chaîne 53.The second rack drive chain 63 also has its tensioner 631, as well as a guide in the upper part, to bring it substantially in alignment at this level on the upper part of the chain 53.

Les seconds moyens d'entraînement 60 comprennent eux aussi des flasques latéraux 74.The second drive means 60 also include lateral flanges 74.

Il est avantageux que ceux-ci permettent aussi le logement d'une troisième chaîne 73 enroulée sur des galets d'extrémités 733 et 734, la partie utile de cette chaîne étant cette fois sa partie inférieure, qui déborde largement vers la droite la partie utile (supérieure) de la chaîne 63.It is advantageous that these also allow the housing of a third chain 73 wound on end rollers 733 and 734, the useful part of this chain being this time its lower part, which extends far to the right the useful part (upper) of chain 63.

Dans la partie gauche des seconds moyens d'entraînement 60, le soutien des claies peut être assuré par des rouleaux comme précédemment. Par contre, dans sa partie droite au moins (mais ceci peut être étendu aussi à la partie gauche), les bas des montants latéraux 71 des claies sont supportés non plus par des rouleaux, mais par des galets, comme illustré en 69 sur les figures 2, 2A et 2C.In the left part of the second drive means 60, the support of the racks can be provided by rollers as before. On the other hand, at least in its right part (but this can also be extended to the left part), the bottoms of the lateral uprights 71 of the racks are no longer supported by rollers, but by rollers, as illustrated at 69 in the figures 2, 2A and 2C.

Ces figures font apparaître comment le tasseau inférieur 71 B des montants 71 est supporté dans une gorge de section trapézoïdale symétrique que comporte un tel galet 69.These figures show how the lower cleat 71 B of the uprights 71 is supported in a groove of symmetrical trapezoidal section that such a roller 69 includes.

La figure 2B fait encore apparaître le plateau 85 qui supporte le fond CT d'un chariot de transport (le reste du chariot n'est pas représenté pour simplifier). Une claie C8 vient d'être mise en place sur ce chariot, par actionnement conjoint des chaînes 63 et 73.FIG. 2B again shows the plate 85 which supports the CT bottom of a transport cart (the rest of the cart is not shown for simplicity). A C8 rack has just been placed on this carriage, by joint actuation of the chains 63 and 73.

Un chariot de transport comprend généralement des supports latéraux 86 qui gênent le bon alignement des nouvelles claies sur le plateau 85. Avantageusement, deux galets poussoirs 79 placés chacun à l'extrémité d'un bras 78 assurent par un mouvement circulaire un bon alignement de chaque nouvelle claie posée sur le chariot.A transport trolley generally comprises lateral supports 86 which hinder the good alignment of the new racks on the plate 85. Advantageously, two push rollers 79 each placed at the end of an arm 78 ensure by a circular movement a good alignment of each new rack placed on the carriage.

Il est maintenant fait référence aux figures 3A et 3B pour la description de l'élévateur à plateau.Reference is now made to FIGS. 3A and 3B for the description of the platform elevator.

L'embase 81 de celui-ci supporte donc un montant 82, qui peut être simplement une poutre de section carrée, munie en partie inférieure d'un galet 832 et en partie supérieure d'un galet 834 associé à un moteur non représenté. Entre ces deux galets circule une chaîne 83.The base 81 of the latter therefore supports an upright 82, which can simply be a beam of square section, provided in the lower part with a roller 832 and in the upper part with a roller 834 associated with a motor not shown. Between these two rollers runs a chain 83.

Cette chaîne 83 est solidaire d'un coulisseau 84, muni de quatre galets régulièrement répartis à angle droit, et notés 841. Ces galets, qui ont une gorge en V à angle droit, permettent un guidage précis du coulisseau 84 sur la poutre 83. Des organes 840 servent à supporter le plateau 85. Ces organes 840 peuvent être par exemple des galets lisses.This chain 83 is integral with a slide 84, provided with four rollers regularly distributed at right angles, and denoted 841. These rollers, which have a V-shaped groove at right angles, allow precise guidance of the slide 84 on the beam 83. Organs 840 serve to support the plate 85. These organs 840 can for example be smooth rollers.

Le coulisseau 84 supporte le plateau proprement dit 85, formé d'une poutre transversale 851 supportant le plan supérieur 850, dans lequel sont ménagées des cornières 854 et 856 servant de renforcements au droit du passage des roues du chariot porte-claie. Le bon positionnement du chariot est assuré par une cornière centrale 855, tournée vers le haut, et de section en forme de U, évasée aux extrémités.The slide 84 supports the actual plate 85, formed of a transverse beam 851 supporting the upper plane 850, in which are provided angles 854 and 856 serving as reinforcements in line with the passage of the wheels of the rack carrier. The correct positioning of the carriage is ensured by a central angle 855, turned upwards, and of U-shaped section, flared at the ends.

Dans la position la plus basse du plateau 85, les cornières 854 et 856 viennent en alignement sur les rails de guidage 90 et 91 de la figure 1.In the lowest position of the plate 85, the angles 854 and 856 come into alignment with the guide rails 90 and 91 of FIG. 1.

On comprend maintenant que la présente invention permet un fonctionnement en automatisation poussée des installations de traitement de prunes, notamment pour en faire par cuisson des pruneaux, et ce en préservant les investissements acquis, notamment au niveau des claies, des chariots de transport et du four (le cas échéant).It is now understood that the present invention allows operation in advanced automation of plum processing facilities, in particular for making them by cooking prunes, and this while preserving the investments acquired, in particular at the level of racks, transport trolleys and oven. (if applicable).

En effet, les seules opérations requises sont le remplissage du bac 1, l'apport de nouvelles claies sur les chaînes 5A, 5B, et le transfert des chariots pleins de claies sur les rails vers le four 9.In fact, the only operations required are the filling of the tray 1, the supply of new racks on the chains 5A, 5B, and the transfer of the carriages full of racks on the rails to the oven 9.

L'ensemble de ces opérations peut aisément être effectué par une seule personne.All of these operations can easily be carried out by a single person.
