Description

On sait que dans le domaine du conditionnement en paquet de conteneurs de fruits et légumes au moyen d'un enveloppement de filet on utilise normalement un élément tubulaire de section circulaire sur lequel est rapporté un filet destiné à envelopper les conteneurs, ce filet étant groupé en spires étroites le long de la surface extérieure de l'élément tubulaire dénommé "tube porte-filet".It is known that in the field of packaging in packages of fruit and vegetable containers by means of a net wrapping, a tubular element of circular section is normally used on which a net intended to wrap the containers is attached, this net being grouped in narrow turns along the outside surface of the tubular element called "net holder tube".

Après fermeture préalable de l'extrémité avant du filet enveloppant ledit tube, de manière à former ainsi un long boyau de filet, les différents conteneurs de fruits et légumes sont transférés à la main à l'intérieur du tube jusqu'à quand ceux-ci sortant de l'autre extrémité, fermée par le boyau de filet, sont complètement envelop- pés par le filet, à l'exception de leur partie arrière. C'est ensuite l'opérateur qui s'occupe de saisir le bout de filet en amont de chaque conteneur, c'est-à-dire la partie reliée au tube porte-filet, et de placer ce bout en correspondance de la tête d'un normal groupe mécanique de fermeture,au moyen d'agrafes,et de coupe dudit bout. De cette façon le premier conteneur est enveloppé en paquet par le filet et la partie restante de filet, immédiatement en amont du conteneur empaqueté, est fermée de nouveau à son extrémité avant et prête à recevoir un deuxième panier.After prior closing of the front end of the net enveloping said tube, so as to form a long net hose, the various containers of fruits and vegetables are transferred by hand inside the tube until when these leaving the other end closed by the tube net are completely envelop - oped by the score, with the exception of their rear part. It is then the operator who takes care of entering the end of the net upstream of each container, that is to say the part connected to the net-carrying tube, and of placing this end in correspondence with the head of the net. 'A normal mechanical group for closing, by means of staples, and for cutting said end. In this way the first container is wrapped in a packet by the net and the remaining part of the net, immediately upstream of the packaged container, is closed again at its front end and ready to receive a second basket.

Evidemment ce système a besoin d'importante main-d'oeuvre et résulte assez lent quant à production horaire de conteneurs enveloppés de filet en paquet. Ev idemment this system requires significant labor and resulting slow enough as to hourly production of containers wrapped package in net.

Une autre solution,partiellement automatisée, conçoit un châssis sur lequel est disposé un tube porte-filet prévoyant un canal de passage des conteneurs à l'intérieur du tube, le long duquel un élément longitudinal pourvu d'une pluralité de saillies peut se déplacer, à l'intérieur d'une glissière, alternativement dans un sens et dans l'autre. Lesdites saillies sont équidistantes l'une de l'autre et espacées d'une distance égale à la longueur d'un conteneur et sont envisagées en vue de déterminer une référence unidirectionnelle dans le sens de sortie de chaque conteneur, du tube,de manière à causer chaque fois le déplacement d'un pas de chaque conteneur de l'entrée à la sortie du tube. De cette façon, la seule opération d'enveloppement de filet en paquet autour de chaque conteneur devient partiellement automatique, du fait qu'il faut toujours la présence d'un opérateur chargé de la main-d'oeuvre nécessaire pour l'opération de mise en place des bouts de filet en correspondance d'un groupe mécanique de fermeture et de coupe desdits bouts de filet, comme mentionné.Another solution, partially automated, designs a frame on which is placed a net-carrying tube providing a container passage channel inside the tube, along which a longitudinal element provided with a plurality of projections can move, inside a slide, alternately in one direction and in the other. Said projections are equidistant from each other and spaced by a distance equal to the length of a container and are envisaged in order to determine a unidirectional reference in the direction of exit of each container, from the tube, so as to cause each container to move one step from the inlet to the outlet of the tube. In this way, the only operation of wrapping the net in a package around each container becomes partially automatic, since it always requires the presence of an operator responsible for the labor necessary for the placing operation. in place of the ends of the net in correspondence with a mechanical group for closing and cutting said ends of the net, as mentioned.

La présente invention vise à pallier ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, résoud le problème de rendre complètement automatique le conditionnement en paquet de conteneurs de fruits et légumes au moyen d'enveloppements de filet et l'application sur ceux-ci de bandes de support et étiquettes, par l'intermédiaire de plusieurs postes disposés en ligne. Notamment, l'appareillage en question comporte un poste d'alimentation de conteneurs qui passent ensuite à l'intérieur d'un tube porte-filet et sont délivrés à un poste d'enveloppement de filet en paquet autour de chaque conteneur, où il y a également un poste d'application des bandes de support des conteneurs et un poste d'étiquetage de ceux-ci, tous les postes agissant en phase et automatiquement.The present invention aims to overcome these drawbacks. The invention, as characterized in the claims, solves the problem of making the packaging of fruit and vegetable containers in a package completely automatic by means of net wraps and the application of support strips thereon. and labels, through several dis stations asked online. In particular, the apparatus in question comprises a container feeding station which then passes inside a net-carrying tube and is delivered to a net wrapping station in bundles around each container, where there also has a station for applying container support strips and a station for labeling the containers, all stations acting in phase and automatically.

Les avantages obtenus grâce à cette invention résident essentiellement dans une production horaire très élevée de conteneurs conditionnés et dans l'absence presque totale de main-d'oeuvre, du fait qu'il suffit de disposer les conteneurs sur le poste d'alimentation.The advantages obtained thanks to this invention lie essentially in a very high hourly production of conditioned containers and in the almost total absence of labor, because it suffices to have the containers on the supply station.

Notamment, le poste d'alimentation 12 comporte, depuis amont vers aval: un premier convoyeur 13 des conteneurs, maintenus sur celui-ci l'un à côté de l'autre; un deuxième convoyeur 14 qui est pourvu d'une vitesse plus élevée que le premier en vue d'éloigner légèrement les conteneurs l'un de l'autre; ledit tube 1 porte-filet assujetti au moteur 32, qui effectue le transfert automatique des conteneurs C du deuxième convoyeur 14 au poste 17 d'enveloppement de filet, comme éclairci par la suite.In particular, the feed station 12 comprises, from upstream to downstream: a first conveyor 13 of the containers, held thereon one next to the other; a second conveyor 14 which is provided with a higher speed than the first in order to move the containers slightly apart from one another; said tube 1 net holder subject to the motor 32, which performs the automatic transfer of the containers C from the second conveyor 14 to the station 17 for wrapping the net, as clarified below.

Les deux convoyeurs sont actionnés par un moteur 16 qui, à travers un normal système cinématique comportant un pignon 65, une chaîne 66 et un pignon 67, transmet le mouvement rotatoire à un premier arbre 68 coïncidant avec l'arbre moteur du convoyeur 13. Sur cet arbre est monté de manière fixe un deuxième pignon 69 (plus large que les autres) et, à travers une chaîne 70 et un pignon 71 (plus petit que les autres), il cause la rotation d'un deuxième arbre 72, coïncidant avec l'arbre moteur du convoyeur 14. De cette façon lé convoyeur 13 avance à une vitesse inférieure par rapport au convoyeur 14.The two conveyors are actuated by a motor 16 which, through a normal kinematic system comprising a pinion 65, a chain 66 and a pinion 67, transmits the rotary movement to a first shaft 68 coinciding with the motor shaft of the conveyor 13. On this shaft is fixedly mounted a second pinion 69 (wider than the others) and, through a chain 70 and a pinion 71 (smaller than the others), it causes the rotation of a second shaft 72, coinciding with the drive shaft of the conveyor 14. In this way the conveyor 13 advances at a lower speed relative to the conveyor 14.

Le premier convoyeur 13 comporte deux chaînes 33 et 34 sans fin,entourant deux pignons correspondants 35 et 36, disposées parallèlement à côté l'une de l'autre et reliées par une pluralité de rouleaux 37 de largeur légèrement supérieure à celle de chaque conteneur C. Par contre, le deuxième convoyeur 14 comporte au moins une paire de courroies 38 et 39 (dont la branche supérieure est placée au même niveau que le plan défini par les rouleaux à rotation libre 37 )qui entourent formant anneau des poulies correspondantes 40 et 41 disposées parallèlement l'une à côté de l'autre et écartées l'une de l'autre d'une distance apte à permettre l'entrée de l'extrémité arrière 4b d'une pièce longitudinale 4 mobile et employée pour le transfert automatique des conteneurs C à l'intérieur du tube 1 porte-filet, tel qu'illustré plus en détail par la suite. Enfin les poulies avant 41 ont un rayon plus large que la hauteur ou épaisseur de la même pièce longitudinale 4 en vue de permettre en tout cas la libre entrée de cette pièce entre lesdites courroies 38 et 39.The first conveyor 13 comprises two endless chains 33 and 34, surrounding two corresponding pinions 35 and 36, arranged parallel to one another and connected by a plurality of rollers 37 of width slightly greater than that of each container. C. On the other hand, the second conveyor 14 comprises at least one pair of belts 38 and 39 (the upper branch of which is placed at the same level as the plane defined by the freely rotating rollers 37) which surround the corresponding pulleys 40 forming a ring. 41 arranged parallel one beside the other and spaced from each other by a distance suitable for allowing the entry of the rear end 4b of a longitudinal piece 4 movable and used for automatic transfer containers C inside the tube 1 net holder, as illustrated in more detail below. Finally, the front pulleys 41 have a wider radius than the height or thickness of the same longitudinal part 4 in order to allow in any case the free entry of this part between said belts 38 and 39.

Le tube 1 qui supporte le filet 2 fermé à son extrémité avant 2a de manière à former un long boyau de filet recueilli sur la surface extérieuredu même tube 1, est pourvu à son intérieur d'un canal 3 de passage des conteneurs dans le tube. Dans ce canal la pièce longitudinale 4 peut se déplacer, le long d'une glissière, alternativement dans les deux sens, cette pièce étant pourvue d'une pluralité de saillies 5 équidistantes, espacées l'une de l'autre d'une distance au moins égale à la longueur d'un conteneur C. Ces saillies 5 sont maintenues élastiquement relevées mais elles peuvent tourner dans le sens S indiqué sur la figure 3 chaque fois que la pièce longitudinale 4 recule et la saillie 5 vient buter contre le bord avant de chaque conteneur C. De cette façon chaque saillie 5 définit une référence unidirectionnelle dans le sens de sortie de chaque conteneur, du tube 1,de manière à causer le déplacement d'un pas à la fois de chaque conteneur de l'entrée à la sortie du tube.The tube 1 which supports the net 2 closed at its front end 2a so as to form a long net hose collected on the outside surface of the same tube 1, is provided inside a channel 3 for passage of the containers in the tube. In this channel, the longitudinal part 4 can move, along a slide, alternately in both directions, this part being provided with a plurality of equidistant projections 5, spaced from each other by a distance from the less equal to the length of a container C. These projections 5 are held elastically raised but they can rotate in the direction S indicated in FIG. 3 each time that the longitudinal part 4 moves back and the projection 5 abuts against the front edge of each container C. In this way each projection 5 defines a unidirectional reference in the direction of output of each tale neur, of tube 1, so as to cause the displacement of one step at a time of each container from the inlet to the outlet of the tube.

La pièce longitudinale 4 effectue son déplacement alternatif dans les deux sens d'une première position extrême reculée, dans laquelle son extrémité arrière 4b pénètre partiellement à l'intérieur du deuxième convoyeur 14, entre les courroies 38 et 39, pour enlever un conteneur C qui se trouve ici en attente, à une deuxième position extrême avancée dans laquelle chaque conteneur C se déplace en avant d'un pas.The longitudinal part 4 performs its reciprocating movement in both directions from a first remote end position, in which its rear end 4b partially penetrates inside the second conveyor 14, between the belts 38 and 39, to remove a container C which is here waiting, at a second extreme advanced position in which each container C moves in front of a step.

Une cellule photoélectrique 15, disposée immédiatement en aval du deuxième convoyeur 14, quand elle est obscurcie par un conteneur C, arrête le circuit d'alimentation du moteur 16, de manière à permettre à la pièce longitudinale 4 de recueillir chaque conteneur qui obscurcit la cellule photo-électrique 15 pour le transférer successivement en avant d'un pas.A photoelectric cell 15, placed immediately downstream of the second conveyor 14, when it is obscured by a container C, stops the power supply circuit of the motor 16, so as to allow the longitudinal part 4 to collect each container which obscures the cell photoelectric 15 to transfer it successively in front of a step.

Ledit groupe de fermeture et de coupe 6 du filet (figure 7) est disposé en aval du tube 1 et sur le même châssis T. Ce groupe comporte une tête de fermeture et de coupe 6a, agissant transversalement sur le filet 2 qui doit être fermé et coupé, par rapport au sens d'avance des conteneurs. Les intervalles non opératoires de la tête 6a commencent sur déclenchement d'un micro-interrupteur 7 (figure 5) qui peut être contacté par une came 8 appliquée à l'arbre de sortie 9 d'un motoréduc- teur 10 de commande du groupe de fermeture et de coupe.Said closing and cutting group 6 of the thread (FIG. 7) is arranged downstream of the tube 1 and on the same frame T. This group comprises a closing and cutting head 6a, acting transversely on the thread 2 which must be closed and cut, relative to the direction of advance of the containers. The non-operating intervals of the head 6a start on triggering of a microswitch 7 (FIG. 5) which can be contacted by a cam 8 applied to the output shaft 9 of a geared motor 10 for controlling the group of closing and cutting.

Le poste 17 d'enveloppement de filet en paquet autour de chaque conteneur C est complètement disposé sur un chariot 18 de base situé en aval du tube 1 porte-filet, soutenu de manière coulissante par le châssis T et mobile alternativement dans les deux sens selon la direction d'avance des conteneurs C.The station 17 for wrapping the net in a packet around each container C is completely disposed on a basic carriage 18 located downstream of the tube 1 net holder, slidably supported by the frame T and movable alternately in both directions according to the direction of advance of the C containers.

On a fixé sur le chariot 18, outre le groupe de fermeture et de coupe 6, ledit dispositif à guillotine 19 qui comporte à sa partie inférieure une première paire d'éléments fixes de référence 20, en forme de "V", disposés transversalement par rapport au sens d'avance des conteneurs C et espacés parallèlement l'un de l'autre de manière à recevoir entre eux et en correspondance du sommet du "V", la tête 6a de fermeture et de coupe du groupe correspondant. Au-dessus de ladite première paire d'éléments fixes 20 il y a une deuxième paire d'éléments de référence mobiles 21, en forme de "V" renversé et agissant en opposition aux premiers.Was fixed on the carriage 18, in addition to the closing and cutting group 6, said guillotine device 19 which comprises at its lower part a first pair of fixed reference elements 20, in the shape of a "V", arranged transversely by relative to the direction of advance of the containers C and spaced parallel to one another so as to receive between them and in correspondence of the top of the "V", the head 6a for closing and cutting the corresponding group. Above said first pair of fixed elements 20 there is a second pair of movable reference elements 21, in the form of an inverted "V" and acting in opposition to the first.

Les plans sur lesquels opèrent les éléments de référence 21 sont légèrement décalés par rapport aux plans sur lesquels opèrent les éléments de référence fixes 20. Ces éléments de référence mobiles 21 sont soutenus de manière coulissante par trois colonnes 21a, solidaires du chariot 18. Les éléments 21 peuvent donc se déplacer verticalement dans les deux sens, d'une première position relevée (voir la figure 7), coïncidant avec l'avance maximale du chariot 18 vers le tube 1, à une deuxième position extrême abaissée (voir la figure 8).The planes on which the reference elements 21 operate are slightly offset from the planes on which the fixed reference elements 20 operate. These mobile reference elements 21 are slidably supported by three columns 21a, integral with the carriage 18. The elements 21 can therefore move vertically in both directions, from a first raised position (see FIG. 7), coinciding with the maximum advance of the carriage 18 towards the tube 1, to a second lowered extreme position (see FIG. 8) .

Dans ladite position relevée, les deux paires d'éléments définissent une ouverture rhomboïdale 22 apte à permettre la libre entrée de chaque conteneur C, avec son filet 2 et de deux prolongements 3a destinés à supporter le conteneur C, immédiatement avant son transfert, par la même pièce longitudinale 4, au-delà du dispositif à guillotine 19, où il y a un logement transitoire 23 de réception du conteneur C. Au contraire, dans la deuxiè me position extrême abaissée le chariot 18 se trouve suffisamment en arrière pour empêcher auxdits éléments mobiles 21 de contacter les prolongements 3a de support extrême de chaque conteneur C. Dans cette deuxième position extrême les sommets des "V" de ladite paire d'éléments définissent une petite ouverture 22a suffisante à retenir solidement en position le bout de filet 2b immédiatement en amont de chaque conteneur C, déjà disposé dans son logement transitoire23. Ce dernier comporte en particulier une ligne de rouleaux fous 23a, supportée par deux rebords latéraux 55 solidaires de manchons 56 appliqués aux colonnes 21a en aval du dispositif à guillotine 19. La ligne de rouleaux 23a se maintient au même niveau que le plan de coulissement des conteneurs C du tube 1 grâce à l'action exercée sur la ligne 23a par des ressorts hélicoïdaux 57 interposés entre chaque manchon 56 et le plan du chariot 18. Des ressorts hélicoïdaux 58 sont disposés sur lesdites colonnes 21a au-dessus de chaque manchon 56, en nombre égal à ces derniers, ces ressorts étant élastiquement contactés par la deuxième paire d'éléments de référence mobiles 21 pendant leur trajet final vers ladite position extrême abaissée. Notamment, étant donné que les éléments de référence mobiles 21 sont eux-aussi engagés de manière coulissante avec lesdites colonnes 21a au moyen de manchons correspondants 73, ce seront justement ces manchons 73 qui vien- dront buter contre les ressorts hélicoïdaux 58. Quand les éléments 21 viennent buter contre les ressorts 58, ils amènent pratiquement avec eux le logement transitoire 23 de manière que l'axe du conteneur C y déposé coïncide avec l'axe de ladite petite ouverture 22a. Ce n'est que de cette façon que l'on peut obtenir le meilleur enveloppement de filet en paquet autour de chaque conteneur C. Si en effet chaque conteneur C devait rester sur un logement transitoire 23 fixe, le filet 2 enveloppant le même conteneur serait sujet à se tendre à sa partie supérieure et à se relâcher, au contraire, à sa partie inférieure; il y a en outre la possibilité que le filet 2 puisse être non adhérent à la surface extérieure de tout le conteneur C.In said raised position, the two pairs of elements define a rhomboidal opening 22 capable of allowing the free entry of each container C, with its net 2 and two extensions 3a intended to support the container C, immediately before its transfer, by the same longitudinal piece 4, beyond the device guillotine 19, where there is a transient housing 2 3 for receiving the container C. On the contrary, in the second extreme lowered position the carriage 18 is located sufficiently behind to prevent said movable elements 21 from contacting the support extensions 3a end of each container C. In this second extreme position, the tops of the "V" s of said pair of elements define a small opening 22a sufficient to securely hold in place the end of the net 2b immediately upstream of each container C, already disposed in its transient housing 23. The latter comprises in particular a line of idle rollers 23a, supported by two lateral flanges 55 integral with sleeves 56 applied to the columns 21a downstream of the guillotine device 19. The line of rollers 23a is maintained at the same level as the plane of sliding of the containers C of the tube 1 by virtue of the action exerted on the line 23a by helical springs 57 interposed between each sleeve 56 and the plane of the carriage 18. Helical springs 58 are arranged on said columns 21a above each sleeve 56, in number equal to the latter, these springs being elastically contacted by the second pair of movable reference elements 21 during their final path to said extreme lowered position. In particular, since the movable reference elements 21 are also slidably engaged with said columns 21a by means of corresponding sleeves dent 73, it will be precisely these sleeves 73 which vien- dron t abut against the coil springs 58. When the elements 21 abut against the springs 58, they take with them practically transitional housing 23 so that the axis of the container C. deposited there coincides with the axis of said small opening 22a. It is only in this way that the best net wrapping in a package can be obtained around each container C. If indeed each container C were to remain on a fixed transitional housing 23, the net 2 enveloping the same container would be subject to stretch at its upper part and to relax, on the contrary, at its lower part; there is also the possibility that the net 2 may be non-adherent to the exterior surface of the entire container C.

L'activation de ladite tête de fermeture et de coupe 6a se produit donc quand l'axe longitudinal du conteneur C est coïncident avec l'axe de la petite ouverture 22a, étant donné qu'à cet instant-là le conteneur C a atteint sa position optimale par rapport aux organes de travail. Un plan incliné à rouleaux fous 23b est articulé en aval de ladite ligne de rouleaux fous 23a, les rouleaux du plan incliné 23b étant soutenus par des rebordslatéraux 59 et ce plan étant pourvu, en sortie, d'une paire de galets 60, mobiles dans des glissières le long d'un plan fixe 61 de liaison de la sortie du plan incliné 23b à un poste 62 de récolte de tous les conteneurs conditionnés (figure 6). De cette façon le plan incliné 23b suit le déplacement du logement transitoire 23 librement et en même temps il sert de-guidage aux conteneurs C vers ledit poste 62 de récolte de ceux-ci.The activation of said closing and cutting head 6a therefore occurs when the longitudinal axis of the container C is coincident with the axis of the small opening 22a, since at this time the container C has reached its optimal position in relation to the working organs. An inclined plane with idle rollers 23b is articulated downstream of said line of idle rollers 23a, the rollers of the inclined plane 23b being supported by lateral flanges 59 and this plane being provided, at the outlet, with a pair of rollers 60, movable in slides along a fixed plane 61 connecting the outlet of the inclined plane 23b to a station 62 for collecting all the conditioned containers (FIG. 6). In this way the inclined plane 23b follows the movement of the transient housing 23 freely and at the same time it serves as a guide for the containers C towards said station 62 for collecting these.

En ce qui concerne encore le poste 17 d'enveloppement de filet autour des conteneurs et en particulier le groupe de fermeture et de coupe 6, il faut remarquer qu'une cellule photo-électrique est disposée en correspondance dudit dispositif à guillotine 19; quand cette cellule photo-électrique, indiquée en 54, est obscurcie par un passage du conteneur C; elle active un microinterrupteur de proximité M2 (figure 5), disposé le long du parcours du chariot 18 et destiné à-causer l'intervention de la tête de fermeture et de coupe 6a quand ledit chariot 18 se trouve dans ladite position reculée qui correspond à la deuxième position extrême abaissée des deuxièmes éléments de référence mobiles 21.As regards the post 17 for wrapping the net around the containers and in particular the closing and cutting group 6, it should be noted that a photoelectric cell is arranged in correspondence with said guillotine device 19; when this photoelectric cell, indicated at 54, is obscured by a passage of the container C ; it activates a proximity microswitch M 2 (FIG. 5), placed along the path of the carriage 18 and intended to cause the intervention of the closing and cutting head 6a when said carriage 18 is in said remote position which corresponds to the second lowered extreme position of the second movable reference elements 21.

Evidemment, si la cellule photo-électrique 54 n'est pas obscurcie, ou bien si les conteneurs C à conditionner sont finis, la tête de fermeture ne pourra pas intervenir.Obviously, if the photoelectric cell 54 is not obscured, or if the containers C to be conditioned are finished, the closing head cannot intervene.

Le poste 24 pour l'application des bandes 26 de support des conteneurs comporte une bobine 25, contenant une longue bande 26a, supportée par un câdre T' fixé à son tour au châssis T à l'avant du dispositif à guillotine 19. La bande 26a est évidemment libre de se dérouler de la même bobine. Avant l'activation de tout l'appareillage, l'opérateur s'occupera de faire passer la bande 26a d'abord à travers une bague 27 disposée sur la bouche de sortie 1a du tube porte-filet (figure 6), puis à l'intérieur d'une boucle 28 ménagée en correspondance du sommet de l'élément de référence mobile 21 plus en amont, et ensuite de fixer la bande 26a en correspondance de la fermeture 2a du long boyau de filet supporté par le tube 1. Evidemment cette première fermeture et fixation de la bande 26a peut être obtenue à la main. A partir de ce moment, chaque fermeture et coupe du filet détermine également la correspondante fixation de la bande 26a aux conteneurs C.The station 24 for the application of the container support strips 26 comprises a coil 25, containing a long strip 26a, supported by a frame T 'fixed in turn to the frame T at the front of the guillotine device 19. The strip 26a is obviously free to unwind from the same reel. Before activating all the equipment, the operator will take care of passing the strip 26a first through a ring 27 disposed on the outlet mouth 1a of the net holder tube (Figure 6), then 'interior of a loop 28 formed in correspondence of the top of the movable reference element 21 further upstream, and then to fix the strip 26a in correspondence of the closure 2a of the long net hose supported by the tube 1. Obviously this first closure and fixing of the strip 26a can be obtained by hand. From this moment, each closing and cutting of the net also determines the corresponding fixing of the strip 26a to the containers C.

Le poste 29 d'étiquetage, en aval du groupe 11 d'alimentation des étiquettes, qui fournit deux étiquettes 30 à la fois, reliées par un fil, comporte un couloir incliné 31, appliqué à côté de ladite première paire d'éléments de référence fixes 20. Ce couloir incliné est utilisé pour le transfert par gravité de deux étiquettes 30 du groupe 11 jusqu'au sommet du "V" desdits éléments de référence fixes 20, où ladite tête de fermeture et de coupe 6a agit. Les étiquettes .30 qui passent deux à deux sur le couloir incliné 31 se présentent pendillan- tes aux deux côtés du même couloir incliné 31 (l'une d'un côté et l'autre de l'autre côté), de manière que chaque intervention de la tête de fermeture et coupe 6a cause l'application simultanée d'une étiquette 30 sur deux conteneurs C à la fois.The labeling station 29, downstream of the label supply group 11, which supplies two labels 30 at the same time, connected by a wire, has an inclined passage 31, applied next to said first pair of reference elements fixed 20. This inclined passage is used for the gravity transfer of two labels 30 from group 11 to the top of the "V" of said fixed reference elements 20, where said closing and cutting head 6a acts. The labels .30 which pass in pairs on the inclined corridor 31 are hanging down on both sides of the same inclined corridor 31 (one on one side and the other on the other side), so that each intervention of the closure head and cutting 6a causes the simultaneous application of a label 30 on two containers C at the same time.

Le seul moteur principal 32 précédemment mentionné actionne simultanément et en phase la pièce longitudinale 4, les deuxièmes éléments de référence mobiles 21 et le chariot de base 18. Cela a lieu à travers des systèmes de poussée bielle-manivelle correspondants 42, 43 et 44 pour la pièce longitudinale 4, les éléments de référence mobiles 21 et le chariot de base 18 respectivement. Les phases exactes de tous les appareils de manutention sont assurées par les déphasages opportuns entre les manivelles correspondantes 42a, 43a et 44a respectivement, qui tournent toutes à la même vitesse angulaire (voir la figure 3).The only main motor 32 previously mentioned operates simultaneously and in phase the longitudinal part 4, the second movable reference elements 21 and the basic carriage 18. This takes place through corresponding rod-crank thrust systems 42, 43 and 44 for the longitudinal part 4, the movable reference elements 21 and the base carriage 18 respectively. The exact phases of all handling devices are ensured by the appropriate phase shifts between the corresponding cranks 42a, 43a and 44a respectively, which all rotate at the same angular speed (see Figure 3).

Les longueurs de la manivelle 42a, de la bielle 42b et du coulisseau 42c se référant au système de poussée bielle-manivelle 42, les longueurs de la manivelle 43a, de la bielle 43b et du coulisseau correspondant coïncidant avec le chariot 18, se référant au système de poussée biel le-manivelle 43, et les longueurs de la manivelle 44a, de la bielle 44b et du coulisseau 44c, se référant au système de poussée bielle-manivelle 44 sont exclusivement déterminées par les positions prises, dans l'espace, respectivement par la pièce longitudinale 4, par les deuxièmes éléments de référence mobiles 21 et par le chariot de base 18.The lengths of the crank 42a, the connecting rod 42b and the slide 42c referring to the rod-crank thrust system 42, the lengths of the crank 43a, the connecting rod 43b and the corresponding slide coinciding with the carriage 18, referring to the biel le-crivelle pushing system 43, and the lengths of the crank 44a, of the connecting rod 44b and of the slide 44c, referring to the connecting rod-crank pushing system 44 are exclusively determined by the positions taken, in space, respectively by the longitudinal part 4, by the second movable reference elements 21 and by the base carriage 18.

Dans la forme d'exécution représentée sur les dessins annexés, à simple titre d'exemple, le déphasage entre la manivelle 42a et la manivelle 43a est d'environ 110°, tandis que le déphasage entre la manivelle 42a et la manivelle 44a est de peu inférieur à 1800.In the embodiment shown in the accompanying drawings, by way of example, the phase shift between the crank 42a and the crank 43a is approximately 110 °, while the phase shift between the crank 42a and the crank 44a is little less than 180 0 .

Il faut remarquer en outre que les manivelles 42a, 43a et 44a sont pratiquement obtenues au moyen de disques 45, 46 et 47 respectivement, dont le rayon est évidemment égal à la longueur des manivelles correspondantes. De cette manière les manivelles font également fonction de "volant", en vue de rendre les différentes opérations de manutention plus douces et sans vibrations, surtout en correspondance des points morts.It should also be noted that the cranks 42a, 43a and 44a are practically obtained by means of discs 45, 46 and 47 respectively, the radius of which is obviously equal to the length of the corresponding cranks. In this way the cranks also act as a "flywheel", in order to make the various handling operations smoother and without vibrations, especially in correspondence with dead centers.

Sur le pourtour du disque 47 il y a une saillie 52 destinée à contacter de manière cyclique une soupape 53, supportée par le châssis T, laquelle déclenche un dispositif pneumatique de type connu qui envoie de l'air de nettoyage à l'intérieur de la tête de fermeture et de coupe 6a après chaque intervention de celle-ci.On the periphery of the disc 47 there is a projection 52 of the tine to cyclically contact a valve 53, supported by the frame T, which triggers a pneumatic device of known type which sends cleaning air inside the closure and cutting head 6a after each intervention of that -this.

Le coulisseau 42c, relatif au système de poussée bielle-manivelle 42 de la pièce longitudinale 4, se maintient sur l'horizontale, du fait qu'il est guidé par un manchon horizontal 74. En outre, le coulisseau 42c est pourvu, sur son extrémité de tête, d'une articulation 48 à laquelle est à son tour articulée une tige 49, solidaire de la pièce longitudinale 4. De même, le bâti T1 de support du tube 1 porte-filet est pourvu à sa partie arrière d'une autre articulation 50 autour de laquelle peut tourner le bâti T quand on désire soulever le tube porte-filet et le remplacer par un autre tube préalablement chargé de filet. Evidemment le bâti T1 ne serait pas en mesure de tourner si l'articulation précitée 48 du coulisseau 42c n'était pas en axe avec l'articulation 50. A cet effet, ona disposé, dans le châssis T, un microinterrupteur M1, susceptible d'être contacté de manière cyclique par une saillie 51 placée par exemple en correspondance du disque 45, de manière qu'il autorise l'arrêt du moteur principal 32, évidemment seulement si le microinterrupteur M1 est activé électriquement, à l'instant dans lequel l'axe 48a de 1 'articulation 48 et l'axe 50a de l'articulation 50 coïncident.The slide 42c, relating to the rod-crank pushing system 42 of the longitudinal piece 4, is maintained on the horizontal, because it is guided by a horizontal sleeve 74. In addition, the slide 42c is provided, on its head end, of a hinge 48 to which a rod 49 is in turn hinged, integral with the longitudinal piece 4. Similarly, the frame T 1 for supporting the tube 1 thread holder is provided at its rear part with another articulation 50 around which the frame T can rotate when it is desired to lift the net-carrying tube and replace it with another tube previously loaded with net. Obviously the frame T 1 would not be able to rotate if the aforementioned articulation 48 of the slide 42c was not in axis with the articulation 50. For this purpose, a micro-switch M 1 has been placed in the chassis T, can be contacted cyclically by a projection 51 placed for example in correspondence with the disc 45, so that it authorizes the stopping of the main motor 32, obviously only if the microswitch M 1 is electrically activated at the moment in which the axis 48a of one joint 48 and the axis 50a of the joint 50 coincide.

Le bâti T1 est également pourvu d'un dispositif 63 de blocage en position abaissée du même bâti T1, Ce dispositif est nécessaire du fait que le bâti T est constamment soumis à une force dirigée vers le haut, appliquée en aval de l'articulation 50 et fournie par un piston à gaz 64 solidaire de la partie inférieure du châssis T. De cette façon, une fois débloqué le dispositif 63, le soulèvement du bâti T est automatique.The frame T 1 is also provided with a device 63 for locking in the lowered position of the same frame T 1 , This device is necessary because the frame T is cons strongly subjected to an upward force, applied downstream of the joint 50 and supplied by a gas piston 64 secured to the lower part of the chassis T. In this way, once the device 63 is released, the lifting of the frame T is automatic.

Comme déjà précisé, les figures 4, 5, 6, 7, 8 et 9 donnent une représentation des différentes phases, en séquence, des opérations qui sont effectuées depuis la sortie de chaque conteneur C, du tube 1 porte-filet jusqu'à son éjection vers le poste de récolte 62.As already specified, FIGS. 4, 5, 6, 7, 8 and 9 give a representation of the different phases, in sequence, of the operations which are carried out from the outlet of each container C, from the tube 1 to the net holder to its ejection to the harvesting station 62.

Sur la figure 4 on peut voir un conteneur C qui va se présenter en correspondance de la bouche de sortie la du tube 1. Dans cette situation le chariot 18 est en train de s'approcher de la bouche la et les éléments de référence mobiles 21 sont en train de se déplacer vers le haut pour atteindre progressivement la position d'ouverture suffisante à permettre le passage du conteneur C, de la pièce longitudinale 4 et des prolongements 3a. Pendant cette phase le groupe d'alimentation étiquettes 11 fournit une paire d'étiquettes tandis que le groupe de fermeture et de coupe 6 est inactif.In FIG. 4 we can see a container C which will appear in correspondence with the outlet mouth 1a of the tube 1. In this situation the carriage 18 is approaching the mouth 1a and the movable reference elements 21 are moving upward to gradually reach the open position sufficient to allow the passage of the container C, the longitudinal part 4 and the extensions 3a. During this phase, the label feed group 11 supplies a pair of labels while the closing and cutting group 6 is inactive.

La figure 5 montre, selon une vue en perspective opposée à la précédente, que le conteneur C, par effet de la pièce longitudinale 4,est avancé encore davantage ainsi que le chariot 18, alors que la paire d'éléments de référence mobiles 21 a subi un autre déplacement vers le haut.Figure 5 shows, in a perspective view opposite to the previous one, that the container C, by effect of the longitudinal part 4, is advanced even more as the carriage 18, while the pair of movable reference elements 21a suffered another upward shift.

Sur la figure 6 on peut voir que le conteneur C est en train de passer à travers l'ouverture rhombofdale 22, obscurcissant la cellule photo-électrique 54 et activant le microinterrupteur de proximité M2 qui est ainsi préparé, au retour en arrière du chariot 18, à effectuer la fermeture et la coupe du filet.In Figure 6 we can see that the container C is in passing through the rhombofdale opening 22, obscuring the photoelectric cell 54 and activating the proximity microswitch M 2 which is thus prepared, when going backwards from the carriage 18, to close and cut the net.

La figure 7 montre la position de rapprochement maximal du chariot 18, de la bouche de sortie du tube 1 porte-filet. Le conteneur C est déjà passé à travers l'ouverture 22 et est déjà disposé sur le logement transitoire 23. Dans cette situation les éléments de référence mobiles 21 sont déjà en train de descendre, alors que la pièce longitudinale 4 et les prolongements 3a dès ce moment commencent à se déplacer en arrière. Par rapport à la position représentée sur la figure 7, les éléments mobiles 21 descendent progressivement, le chariot 18 recule jusqu'à quand il contacte le microinterrupteur de proximité M2 qui déclenche l'action de la tête de fermeture et de coupe 6a, tel que représenté sur la figure 8. Pendant que les étiquettes 30 sont déjà disposées en correspondance de la tête 6a, la bande 26a vient se superposer au bout de filet 2b, de manière que l'opération de fermeture et de coupe est effectuée non seulement sur le filet 2 mais aussi sur la bande 26a et sur les étiquettes 30.Figure 7 shows the position of maximum approximation of the carriage 18, the outlet of the tube 1 thread holder. The container C is already passed through the opening 22 and is already disposed on the transient housing 23. In this situation the movable reference elements 21 are already going down, while the longitudinal part 4 and the extensions 3a from this moment begin to move back. Compared to the position shown in Figure 7, the movable elements 21 descend gradually, the carriage 18 moves back until when it contacts the proximity microswitch M 2 which triggers the action of the closing and cutting head 6a, such as shown in FIG. 8. While the labels 30 are already arranged in correspondence with the head 6a, the strip 26a is superimposed on the end of the thread 2b, so that the closing and cutting operation is carried out not only on the net 2 but also on the strip 26a and on the labels 30.

Quand les éléments de référence mobiles 21 descendent jusqu'à la position de fermeture et de coupe, le logement transitoire 23 a atteint lui-aussi un niveau de descente optimal, tel que précisé plus haut, cette descente n'étant pas empêchés par la présence du plan incliné 23b qui, étant articulé sur le logement transitoire 23 et coulissant sur les galets 60, est disposé à peut près sur l'horizontale.When the movable reference elements 21 descend to the closed and cutting position, the transient housing 23 has also reached an optimal level of descent, as specified above, this descent not being prevented by the presence of the inclined plane 23b which, being articulated on the transi housing roof 23 and sliding on the rollers 60, is arranged roughly on the horizontal.

Enfin,sur la figure 9 on peut voir le conteneur C conditionné, après les différentes opérations. A ce point le chariot 18 avance de nouveau et les éléments de référence mobiles 21 commencent encore leur déplacement vers le haut pour permettre le passage d'un conteneur C suivant, déjà pourvu de l'étiquette 30, en sortie du tube 1 porte-filet, et un nouveau cycle se répète.Finally, in Figure 9 we can see the container C conditioned, after the various operations. At this point the carriage 18 advances again and the movable reference elements 21 still begin their upward movement to allow the passage of a next container C, already provided with the label 30, at the outlet of the tube 1 net holder , and a new cycle is repeated.
