It comprises a perforating tube 4 used to evacuate the package. A perforating suction cup 1 and 2 equipped with seals 8 and 9 and with valves 7 and 11 allow the package to be handled under vacuum. The invention may be used for handling and emptying all sealed flexible packages.

Description

La présente invention a pour objet un procédé de manutention de produits en grandes masses contenus dans des emballages souples, ainsi qu'un dispositif pour la mise en oeuvre de ce procédé. The present invention relates to a process for handling products in large masses contained in flexible packaging, as well as a device for the implementation of this process.

Les produits pulvérulents ou granullés conditionnés en grandes masses dans des emballages souples sont le plus souvent placés dans des contenants rigides pour le transport, compte tenu de la faible résistance de l'emballage souple qui ne sert dans la plupart des cas que d'enveloppe étanche. Powdered or granular products packaged in large masses in flexible packaging are most often placed in rigid containers for transport, given the low resistance of the flexible packaging which in most cases only serves as a waterproof envelope .

La vidange de tels emballage est rendu difficile du fait de la présence à la fois de l'enveloppe souple et du contenant rigide. Emptying such packaging is made difficult due to the presence of both the flexible envelope and the rigid container.

La présente invention vise à palier cet inconvénient. Le procédé selon l'invention est caractérisé par le fait que l'on utilise un dispositif qui permet d'une part de faire le vide à l'intérieur de l'emballage souple et d'autre part de manutentionner l'emballage ainsi mis sous vide à l'aide d'une ventouse qui s'applique sur la surface extérieure de l'enveloppe souple. Le procédé selon l'invention permet, de par la contraction de l'emballage due à la mise sous vide, de désolidariser l'emballage souple du contenant rigide dans lequel il est placé et de le manutentionner indépendemment de celui-ci. The present invention aims to overcome this drawback. The method according to the invention is characterized in that a device is used which makes it possible on the one hand to create a vacuum inside the flexible packaging and on the other hand to handle the packaging thus placed under vacuum using a suction cup which is applied to the outside surface of the flexible envelope. The method according to the invention makes it possible, by the contraction of the packaging due to the vacuum, to separate the flexible packaging from the rigid container in which it is placed and to handle it independently of the latter.

Ce procédé présente de multiples avantages. I1 permet notamment, de séparer l'emballage souple de son contenant rigide, de le transporter jusqu'à l'endroit de la vidange, et de récuperer l'emballage souple après la vidange. This process has multiple advantages. I1 allows, in particular, to separate the flexible packaging from its rigid container, to transport it to the place of emptying, and to recover the flexible packaging after emptying.

Les dessins annexés représentent, à titre d'exemple, un dispositif de mise en oeuvre du procédé selon l'invention. The accompanying drawings show, by way of example, a device for implementing the method according to the invention.

La fig 1 représente une coupe de l'ensemble de la ventouse perforante. Fig 1 shows a section of the assembly of the perforating suction cup.

Un plateau 1 rectangulaire est séparé d'une tole perforée 2 par une espace clos 3 formant caisson. Un tuyau 4 traverse ce caisson, il comporte une extrémité bisautée qui permet la perforation de l'emballage souple. Ce tuyau 4 qui sert à la mise sous vide de l'intérieur de l'emballage comporte des orifices 5, il est équipé d'un filtre 6. Une vanne 7 placée sur le tuyau 4 permet de commander l'aspiration ou le soufflage pour le décolmatage du filtre. Dans la partie médiane du tuyau 4 contre la tôle perforée 2, se trouve un joint 8 d'étanchéité en matériaux souple, ce joint est disposé contre la tôle perforée. Sur le périmétre de la tôle perforée se trouve un autre joint souple 9. Ces joints assurent l'étanchéité entre l'emballage souple et le caisson, utilisé comme ventouse, lors de la manutention, l'emballage souple venant alors s'appliquer sur toute la surface de la tôle perforée.Un autre tuyau 10 trav erse le plateau, il sert à faire le vide à l'intérieur du caisson 3 (volume compris entre le plateau 1 et la tôle perforée 2), ce tuyau comporte une vanne 11 qui commande l'aspiration. Ce tuyau 10 est raccordé à une pompe à vide. A rectangular tray 1 is separated from a perforated sheet 2 by a closed space 3 forming a box. A pipe 4 passes through this box, it has a beveled end which allows the perforation of the flexible packaging. This pipe 4 which is used to evacuate the interior of the packaging has orifices 5, it is equipped with a filter 6. A valve 7 placed on the pipe 4 makes it possible to control the suction or the blowing for unclogging the filter. In the middle part of the pipe 4 against the perforated sheet 2, there is a seal 8 made of flexible material, this seal is disposed against the perforated sheet. On the perimeter of the perforated sheet is another flexible seal 9. These seals ensure the seal between the flexible packaging and the box, used as a suction cup, during handling, the flexible packaging then being applied to any Another perforated sheet 10 crosses the plate, it is used to create a vacuum inside the box 3 (volume between the plate 1 and the perforated sheet 2), this tube includes a valve 11 which controls the suction. This pipe 10 is connected to a vacuum pump.

Un troisième tuyau 12 muni d'une vanne 13 permet d'insuffler de l'air dans le tuyau 4 pour de colmater le filtre 6. Des anneaux de levage 14 servent à la manutention de l'ensemble.A third pipe 12 provided with a valve 13 blows air into the pipe 4 to seal the filter 6. Lifting rings 14 are used for handling the assembly.

Mise en oeuvre du procédé Fig 2, la ventouse perforante est appSguée sur une face de l'emballage souple 15 rempli d'un produit 16. L'emballage souple rempli est disposé dans un contenant rigide 17. De par le poids de de-l'ensemble, le tuyau perforateur 4 traverse la paroi de l'emballage souple, et pénétre à l'intérieur du produit 16. Les joints 8 et 9 viennent au contact de la face plane 15. La vanne 13 étant fermé, les vannes 7 et 11 sont ouvertes, le vide est fait à l'intérieur de l'emballage souple. Lorsque le vide atteint une valeur suffisante à l'intérieur de l'emballage et dans le caisson 3, la manutention peut alors commencer.En effet la surface de l'emballage souple comprise à l'intérieur du périmétre délimité par le joint 9 est appliqué sur la tôle perforée 2, et sur les joints 8 et 9, du fait de la pression atmosphérique qui s'exerce sur les parois extérieures de l'emballage souple. L'ensemble ventouse perforante emballage sous vide, peut alors être sorti du contenant 17 et manutentionné à l'aide des anneaux 14, jusqu'à l'endroit de la vidange, qui peut être un endroit clos dans le cas d'un produit polluant. Pour la vidange, l'emballage sous vide est déposé par la ventouse sur un système qui coupe le fond 18. La vanne 7 est fermée, seul le caisson 3 reste raccordé à la pompe à vide. Implementation of the method FIG. 2, the perforating suction cup is applied to one face of the flexible packaging 15 filled with a product 16. The filled flexible packaging is placed in a rigid container 17. Due to the weight of de-l 'together, the perforator pipe 4 crosses the wall of the flexible packaging, and penetrates inside the product 16. The seals 8 and 9 come into contact with the flat face 15. The valve 13 being closed, the valves 7 and 11 are open, a vacuum is created inside the flexible packaging. When the vacuum reaches a sufficient value inside the packaging and in the box 3, handling can then begin. Indeed the surface of the flexible packaging included inside the perimeter delimited by the seal 9 is applied on the perforated sheet 2, and on the seals 8 and 9, due to the atmospheric pressure which is exerted on the outer walls of the flexible packaging. The vacuum packaging perforating suction cup assembly can then be removed from the container 17 and handled using the rings 14, to the place of emptying, which can be a closed place in the case of a polluting product. . For emptying, the vacuum packaging is deposited by the suction cup on a system which cuts the bottom 18. The valve 7 is closed, only the box 3 remains connected to the vacuum pump.

De par la découpe du fond, le vide est carré à l'intérieur de l'emballage souple, le produit it 16 s'écoule. La vanne 13 est ouverte, de l'air est envoyé dans le tuyau 4 par l'intermédiaire du tuyau 12 raccordé à un appareil de production d'air comprimé. Cette opération permet le décolmatage du filtre 6. Le décolmatage étant terminé la vanne 13 est refermée le caisson 3 étant sous vide, l'emballage souple reste appliqué sur la tôle perforée et peut être évacué par la ventouse après la vidange du produit. A l'endroit de dépose de l'emballage souple vide, la-vanne 11 est fermé, la vanne 7 est ouverte, le caisson étant à l'air libre par l'intermédiaire des tuyaux 4 et 10, l'emballage souple se désolidarise de la ventouse et est déposé. By cutting the bottom, the vacuum is square inside the flexible packaging, the product it 16 flows. The valve 13 is open, air is sent into the pipe 4 via the pipe 12 connected to an apparatus for producing compressed air. This operation allows unclogging of the filter 6. The unclogging being finished the valve 13 is closed the box 3 being under vacuum, the flexible packaging remains applied to the perforated sheet and can be evacuated by the suction cup after the emptying of the product. At the place of removal of the empty flexible packaging, the valve 11 is closed, the valve 7 is open, the box being in the open air by means of the pipes 4 and 10, the flexible packaging dissociates of the suction cup and is removed.
