Description
La présente invention concerne un équipement pour appareil de manutention de charges disposées sur des rayonnages, de part et d'autre d'une allée de circulation, permettant la sortie d'une charge du côté opposé à sa préhension, et comportant un organe de préhension d'une charge stockée sur d'un des rayonnages.The present invention relates to equipment for a device for handling loads arranged on shelves, on either side of a circulation aisle, allowing the exit of a load from the side opposite to its gripping, and comprising a gripping member. of a load stored on one of the shelves.
D'une manière connue, l'organe de préhension est une fourche télescopique. Le caractère télescopique de cette fourche permet d'amener le dernier élément télescopique en position centrée sous une charge, de ramener celle-ci en position centrée sur l'appareil et enfin, par un mouvement inverse de la fourche, de sortir la charge du côté opposé à la préhension. Mais une fourche est relativement épaisse, ce qui augmente son encombrement en hauteur.In a known manner, the gripping member is a telescopic fork. The telescopic nature of this fork makes it possible to bring the last telescopic element to the centered position under a load, to bring the latter to the centered position on the device and finally, by a reverse movement of the fork, to remove the load from the side opposed to gripping. But a fork is relatively thick, which increases its overall height.
On connaît également, par le document FR 1 515 727, un équipement dont l'organe de préhension comporte un plateau porteur de charges et un dispositif de transfert déplaçant une charge d'une extrémité du plateau à l'autre, ce dispositif de transfert comportant deux liens mécaniques souples placés de part et d'autre du plateau et sur chacun desquels sont disposés des taquets. Dans cet équipement, le plateau ne se glisse pas sous la charge, c'est le dispositif de transfert qui amène la charge au-dessus du plateau. La charge est donc obligatoirement posée sur un chariot muni de roulettes, ce qui lui confère un encombrement en hauteur important.Document FR 1 515 727 also discloses equipment, the gripping member of which comprises a load-bearing plate and a transfer device displacing a load from one end of the plate to the other, this transfer device comprising two flexible mechanical links placed on either side of the plate and on each of which are arranged cleats. In this equipment, the plate does not slip under the load, it is the transfer device which brings the load above the plate. The load is therefore necessarily placed on a trolley fitted with rollers, which gives it a significant overall height.
La présente invention a pour but d'augmenter le nombre de rayonnages superposés, dans un hangar de hauteur donné, tout en utilisant des conteneurs du commerce tels que des bacs plastiques.The present invention aims to increase the number of superimposed shelving, in a hanger of given height, while using commercial containers such as plastic bins.
Ce but est atteint en supprimant les chariots et en utilisant un simple plateau que l'on amène seul sous la charge, un dispositif de transfert assurant le déplacement d'une charge d'une extrémité du plateau à l'autre, quand le plateau est situé dans l'allée centrale.This object is achieved by eliminating the carriages and using a simple tray that is brought alone under the load, a transfer device ensuring the movement of a load from one end of the tray to the other, when the tray is located in the central aisle.
La présente invention a pour objet un équipement pour appareil de manutention de charges disposées sur des rayonnages, de part et d'autre d'une allée de circulation, comportant un plateau porteur de charges et un dispositif de transfert déplaçant une charge le long du plateau, ce dispositif de transfert comportant deux liens mécaniques souples placés de part et d'autre du plateau et sur chacun desquels sont disposés des taquets, caractérisé en ce qu'une partie du plateau est amenée sous une charge puis soulevée et ramenée dans d'allée de circulation, les taquets, situés sous le niveau du plateau lors de la préhension ou de la sortie d'une charge, poussant la charge d'une extrémité à d'autre du plateau quand la sortie de la charge est prévue du côté opposé à sa préhension.The present invention relates to equipment for a device for handling loads arranged on shelves, on either side of a circulation aisle, comprising a load-carrying plate and a transfer device displacing a load along the plate. , this transfer device comprising two flexible mechanical links placed on either side of the plate and on each of which are arranged cleats, characterized in that a part of the plate is brought under a load then lifted and brought back in the aisle movement, the tabs, located below the level of the tray when gripping or removing a load, pushing the load from one end to the other of the tray when the load is removed from the side opposite to his grip.
Cet équipement présente, en outre, les caractéristiques suivantes :
- - les deux liens mécaniques sont montés sur deux arbres dont l'un au moins est moteur, ces deux liens pouvant être des chaines, des courroies, des câbles...
- - les quatre taquets sont situés sous le niveau du plateau lors de la préhension ou la sortie d'une charge.

Dans la figure 1, l'équipement, vu en coupe partielle, comporte un chassis 1 soutenant une plaque 2 sur laquelle sont montés un moteur 10, deux axes 11, 12. En bout du moteur 10 un pignon 13 entraîne une couronne dentée 14 montée sur l'axe 11, la couronne 14 entraînant une couronne dentée identique 15 montée sur l'axe 12. La couronne 14 porte un galet 14A et la couronne 15 porte un galet 15A, ces deux galets coopérant chacun avec une gouttière 21 formée entre deux rails 21 A, 21 B d'un chariot 20. Ce chariot 20 est porté en son centre par un arbre 22 cylindrique visible en figure 5, et comporte de chaque côté deux pignons 23 également visibles en figure 5.In Figure 1, the equipment, seen in partial section, comprises a frame 1 supporting a
Ces deux pignons 23 roulent chacun sur une crémaillère 3, ces deux crémaillères étant fixées sur le chassis 1.These two
Les deux pignons 23 sont couplés mécaniquement avec des pignons 24, chaque couple de pignons étant monté sur un axe 25 solidaire du chariot 20.The two
Chaque pignon 24 engrène avec une crémaillère 26 solidaire d'un plateau 30 porté par des galets 31.Each
L'équipement comporte également un moteur 40 entraînant par l'intermédiaire d'un pignon 41 une chaine 42. Cette chaine entraîne, par l'intermédiaire d'un pignon 43, un axe 44 sur lequel sont montés deux pignons 45. Ces deux pignons 45 recoivent chacun une chaine 46 qui est reliée à l'autre extrémité du plateau, à deux pignons 47 montés sur un autre axe 48.The equipment also includes a
Chaque chaine 46 reçoit, à une extrémité du plateau, un taquet 49 et à l'autre extrémité un taquet 50.Each
Cet équipement est installé sur un appareil placé dans une allée qui comporte de chaque côté des rayonnages 61 sur lesquels sont posées des charges 60. En bout de rayonnage, des supports 62 représentés en figure 3, permettent une reprise des charges.This equipment is installed on a device placed in an aisle which has shelving 61 on each side on which tanks are placed.
Dans la figure 2 le plateau est en position sortie et il soutient la charge 60. Cette situation a été obtenue après la sortie du plateau se glissant sous la charge et une légère levée de l'ensemble de l'équipement permettant de décoller la charge des rayonnages 61.In FIG. 2, the plate is in the extended position and it supports the
Dans la figure 3, le plateau a être ramené en position centrale sur l'appareil qui a été lui-même amené en bout de rayonnages pour permettre une sortie de la charge.In FIG. 3, the tray has to be brought back to the central position on the device which has itself been brought to the end of the shelving to allow an exit of the load.
La figure 4 montre, en vue de dessus, le pignon 13 entraînant la couronne dentée 14 qui entraîne elle même la couronne dentée 15.FIG. 4 shows, in top view, the
Cette figure montre clairement les galets 14A, 15A qui s'engagent dans la gouttière 21 du chariot 20.This figure clearly shows the
L'entraînement du chariot, décrit dans le brevet FR-2.504.507 de la demanderesse, apparait clairement dans cette figure. Pour déplacer le chariot vers la droite de la figure, on fait tourner le pignon 13 dans le sens trigométrique.The drive of the carriage, described in patent FR-2,504,507 of the applicant, appears clearly in this figure. To move the carriage to the right of the figure, the
Ce pignon entraîne alors la couronne 14 dans le sens horaire et le galet 14A entraîne le chariot vers la droite de la figure tandis que la couronne 15, tournant dans le sens trigonométrique, dégage le galet 15A de la gouttière 21.This pinion then drives the
Pour ramener le chariot dans sa position centrale, il suffit d'inverser le sens de rotation du pignon 13. De cette position centrale, si l'on continue à faire tourner le pignon 13 dans le même sens, le galet 15A, introduit dans la gouttière 21, entraîne le chariot vers la gauche de la figure tandis que le galet 14A est dégagé de la gouttière 21.To return the carriage to its central position, it suffices to reverse the direction of rotation of the
Dans cette figure 4 on voit également, de façon claire, le moteur 40, le pignon 41, la chaine 42, le pignon 43 et les axes 44 et 48. Chaque chaine 46 porte deux taquets 49 et 50.In this FIG. 4, we can also clearly see the
La figure 5 montre, outre les éléments décrits conjointement avec la figure 1, deux montants 27 assurant le guidage du plateau 30 par l'intermédiaire de roulements à aiguilles 28 qui empêchent le soulèvement du plateau. Cette figure montre également l'entraînement du plateau par le déplacement du chariot 20 dont les pignons 23 roulent sur les crémaillères 3 et les pignons 24 qui engrènent sur les crémaillères 26 solidaires du plateau 30.FIG. 5 shows, in addition to the elements described in conjunction with FIG. 1, two
Bien entendu, un seul pignon 23, placé entre deux crémaillères en vis à vis, permet d'entrainer le plateau à une vitesse double de celle du chariot. La disposition représentée, avec deux pignons 23, 24 et deux crémaillères décalées, permet une multiplication de la vitesse de déplacement et de la course du plateau.Of course, a
Le fonctionnement de cet équipement monté sur un appareil translateur-gerbeur qui permet un déplacement horizontal et vertical dans une allée pour positionner le plateau sous le niveau de la charge que l'on souhaite extraire, est le suivant :The operation of this equipment mounted on a translator-stacker device which allows horizontal and vertical movement in an aisle to position the tray under the level of the load that one wishes to extract, is as follows:
Pour extraire la charge 60, on commande la rotation du moteur 10 qui déplace le chariot 20 comme cela a été expliqué précédemment. Le déplacement du chariot fait sortir le plateau qui se glisse sous la charge, les deux groupes de taquets étant escamotés sous le plateau.To extract the
On soulève l'ensemble de l'équipement pour décoller la charge des rayonnages, cette étape étant représentée en figure 2.The entire equipment is lifted to take off the load from the shelves, this step being shown in FIG. 2.
On ramène le plateau dans sa position centrale et la charge est alors située au bord du plateau en position 60A. Cette position 60A est incompatible avec une sortie de la charge de l'autre côté du plateau sur des supports 62, cette étape étant représentée en figure 3, et c'est à cet instant que les taquets entrent en action.The tray is returned to its central position and the load is then located at the edge of the tray in
On commande la rotation du moteur 40 qui entraîne les chaines 46, ce qui a pour effet d'amener les taquets 50 en appui contre la charge. En continuant d'entraîner les chaînes 46, la charge sera donc transférée de sa position 60A à sa position 60B, à l'autre extrémité du plateau, cette position 60B étant représentée en traits interrompus.The rotation of the
On provoque la sortie du plateau 30 du côté du moteur 40 pour amener la charge 60 au-dessus du support 62 et poser cette charge sur ce support après une légère descente de l'ensemble de l'appareil.It causes the exit of the
En variante, on peut remplacer le support 62 par un convoyeur à chaînes, ce qui présente l'avantage de continuer à pousser la charge par l'intermédiaire des taquets, sans sortir le plateau. Cette variante permet donc de supprimer la course de retour du plateau, et ceci représente un gain de temps appréciable.Alternatively, the
