Abstract

The device has a tubular structure for providing heat-weldable film with respect to a bulk of grain materials fed through a conduit in a controlled manner. The tubular structure includes welded bars, arms and skids provided for support and arranged to move and slide along respective guides in a direction perpendicular to the axle of the conduit. The skids are moved between separate position and coincident position. Two parallel metal rods are arranged perpendicular to the guides for performing rotation operation. A symmetrical support is provided for the metal rods.

Description

La présente invention concerne le remplissage et la fermeture deThe present invention relates to the filling and closing of

récipients contenant un produit en vrac. On connaît déjà des machines qui, à partir d'une bande de matière thermosoudable de qualité alimentaire, forment une structure tubulaire enfilée sur un conduit par lequel est transmis le produit en vrac, par exemple du café en grains. La structure tubulaire subit, à des emplacements équidistants, une opération de soudage et de coupe qui permet de séparer des récipients hermétiquement fermés et contenant une quantité dosée du produit, à partir de la structure tubulaire. L'invention concerne plus précisément des dispositifs de soudage et de coupe de la structure tubulaire.  containers containing a product in bulk. Machines are already known which, from a strip of food-grade heat-sealable material, form a tubular structure threaded onto a pipe through which the bulk product, for example coffee beans, is transmitted. The tubular structure undergoes, at equidistant locations, a welding and cutting operation which makes it possible to separate hermetically sealed containers containing a metered quantity of the product from the tubular structure. The invention more specifically relates to welding and cutting devices of the tubular structure.

De tels dispositifs comprennent deux barres de soudage opposées qui sont fixées sous l'extrémité inférieure du conduit et sont mobiles entre deux positions éloignée et rapprochée, et comportent des dispositifs de coupe qui agissent lorsque les barres sont en position rapprochée.  Such devices comprise two opposed welding bars which are fixed under the lower end of the duct and are movable between two distant and close positions, and have cutting devices which act when the bars are in close position.

Le déplacement des barres de soudage en opposition de phase est réalisé, selon la technique connue, par un système à bielles et manivelles commandé par des organes pneumatiques ou électriques de manoeuvre. Ainsi, ces dispositifs connus ont non seulement une structure complexe, mais en outre un encombrement important qui limite leur utilisation à des modèles particuliers de machines de remplissage et réduit sérieusement leur souplesse d'utilisation. L'invention a pour objet un appareil de fermeture, de soudage et de séparation de récipients formés à partir d'une structure tubulaire, dont la structure est simple et l'encombrement réduit, et qui convient à une large gamme de machines de remplissage comme élément modulaire qui peut fonctionner de façon autonome.  The displacement of the welding bars in opposition of phase is carried out, according to the known technique, by a system with rods and cranks controlled by pneumatic or electric actuating members. Thus, these known devices have not only a complex structure, but also a large footprint that limits their use to particular models of filling machines and seriously reduces their flexibility of use. The invention relates to an apparatus for closing, welding and separating containers formed from a tubular structure, whose structure is simple and compact, and which is suitable for a wide range of filling machines such as modular element that can operate autonomously.

Cet objet est atteint grâce à un appareil de remplis-sage, de fermeture et de séparation de récipients contenant un produit en vrac et formés à partir d'une structure tubulaire constituée d'une feuille thermosoudable disposée concentriquement à un conduit d'alimentation en produit en vrac, comprenant un dispositif destiné à faire descendre en mode commandé la structure tubulaire à l'extérieur du conduit, deux barres de soudage munies de dispositifs de coupe et supportées par des chariots respectifs mobiles sur des guides respectifs afin qu'elles se déplacent dans un plan perpendiculaire à l'axe du conduit au-dessous de l'extrémité de celui-ci, entre une position éloignée et une position rapprochée, et un dispositif destiné à communiquer aux chariots des mouvements de va-et-vient en opposition de phase ; selon l'invention, l'appareil comprend deux arbres fous qui sont perpendiculaires aux guides et obligés de tourner simultanément, chacun supportant au moins une came ayant un profil symétrique de celui de la came portée par l'autre arbre, chaque chariot possédant au moins un toucheau de came qui se déplace contre la came de l'arbre le plus proche, un dispositif étant destiné à provoquer une rotation d'au moins 180' des arbres rotatifs. Selon des caractéristiques avantageuses, les cames sont des cames desmodromiques, chaque arbre porte une came à chaque extrémité, et/ou les arbres sont raccordés par une transmission à courroie. Dans un mode de réalisation, l'un des arbres porte une poulie menée raccordée à une poulie motrice par une trans-mission à courroie. Par exemple, la poulie motrice est montée sur l'arbre d'un moteur électrique à avance commandée, ou la poulie motrice est montée sur un arbre muni d'une manivelle manoeuvrée par un vérin, et, de préférence, la poulie motrice a un diamètre double de celui de la poulie menée. De préférence, le châssis de l'appareil est fixé à la structure d'une machine, ou le châssis est raccordé à la structure de la machine par deux bielles fixées à la partie supérieure de la structure et, à la partie inférieure, de manière excentrique, à quatre disques respectifs montés chacun à l'extrémité de l'un des arbres, le châssis étant guidé afin qu'il se déplace parallèlement à lui même.  This object is achieved by filling-sinking, closing and separating containers containing a bulk product and formed from a tubular structure consisting of a heat-sealable sheet concentrically arranged in a product supply duct. in bulk, comprising a device for driving down the tubular structure outside the conduit in controlled mode, two welding bars provided with cutting devices and supported by respective carriages movable on respective guides so that they move in a plane perpendicular to the axis of the conduit below the end thereof, between a distant position and a close position, and a device for communicating to the carriages back and forth movements in opposition to phase ; according to the invention, the apparatus comprises two crazy shafts which are perpendicular to the guides and forced to rotate simultaneously, each supporting at least one cam having a profile symmetrical to that of the cam carried by the other shaft, each carriage having at least a camming flap which moves against the cam of the nearest shaft, a device being intended to cause a rotation of at least 180 'of the rotary shafts.

Les figures 1 à 5 représentent un conduit fixé rigide 1 sur lequel est enfilée une structure tubulaire 2 formée d'une feuille d'une matière thermosoudable de qualité alimentaire, maintenue en position et qui est déplacée par glissement sur le conduit 1 par deux courroies opposées 3, 33 entraînées en rotation par intermittence par un moteur à avance commandée et une transmission associée. Le dispositif de manoeuvre des courroies 3, 33 est représenté sur la figure 2 et comporte un moteur 100 à avance commandée qui, par un renvoi d'angle 101, entraîne la transmission à courroie 102 et deux engrenages 103, et deux arbres 104 à joints de cardan, qui tournent en sens opposés (un seul est visible sur la figure) et qui sont raccordés chacun à l'une de deux poulies motrices sur lesquelles passe l'une des courroies 3, 33. Deux guides 4, 44 qui sont parallèles et horizontaux (figures 4 et 5), sur lesquels coulissent deux chariots 5, 55, sont placés sous l'extrémité inférieure du conduit 1. Les guides sont supportés chacun par un support central 6, 66 qui dépasse d'un châssis 700 porté par la paroi latérale ou structure 7 de la machine. Deux arbres fous 8 et 88, parallèles l'un à l'autre, perpendiculaires aux guides 4, 44 et dont les axes sont coplanaires, sont supportés entre les parois opposées du châssis 700 de l'appareil. Deux disques circulaires 9, symétriques l'un de l'autre, sont montés aux extrémités de chaque arbre 8 et 88 ; le moyeu des disques est excentrique et les disques portent une came desmodromique 91, qui est circulaire et excentrique par rapport à l'axe de l'arbre respectif 8, 88, et un toucheau de came 92, solidaire du chariot 5, 55 et proche de l'arbre respectif, se déplace contre la came. Dans l'exemple représenté sur les figures 4 et 5, l'arbre 88 possède une poulie intermédiaire 81 raccordée par une transmission à courroie 82 à une poulie 83 dont le diamètre est double de celui de la poulie 81. La poulie 83 est montée sur un arbre 84 qui possède une manivelle 85 dont l'extrémité est raccordée à un vérin 86.  Figures 1 to 5 show a rigid fixed conduit 1 on which is threaded a tubular structure 2 formed of a sheet of a food-grade heat-sealable material, held in position and which is slidably displaced on the conduit 1 by two opposite belts 3,33 intermittently rotated by a controlled feed motor and an associated gear. The drive device of the belts 3, 33 is shown in FIG. 2 and comprises a motor 100 with controlled feedthrough which, by means of an angle gear 101, drives the belt drive 102 and two gears 103, and two joined shafts 104 cardan, which rotate in opposite directions (only one is visible in the figure) and which are each connected to one of two driving pulleys on which passes one of the belts 3, 33. Two guides 4, 44 which are parallel and horizontal (Figures 4 and 5), on which slide two carriages 5, 55, are placed under the lower end of the conduit 1. The guides are each supported by a central support 6, 66 which protrudes from a frame 700 carried by the side wall or structure 7 of the machine. Two shafts 8 and 88, parallel to each other, perpendicular to the guides 4, 44 and whose axes are coplanar, are supported between the opposite walls of the frame 700 of the apparatus. Two circular disks 9, symmetrical to each other, are mounted at the ends of each shaft 8 and 88; the hub of the discs is eccentric and the discs have a desmodromic cam 91, which is circular and eccentric with respect to the axis of the respective shaft 8, 88, and a cam contact 92, integral with the carriage 5, 55 and close of the respective shaft, moves against the cam. In the example shown in Figures 4 and 5, the shaft 88 has an intermediate pulley 81 connected by a belt transmission 82 to a pulley 83 whose diameter is twice that of the pulley 81. The pulley 83 is mounted on a shaft 84 which has a crank 85 whose end is connected to a jack 86.

Le vérin 86 communique à l'arbre 84 des oscillations de 90' qui sont transformées en oscillations de 180' de l'arbre 88. Les deux arbres 8 et 88 sont raccordés afin qu'ils tournent ensemble par une transmission à courroie 87 qui raccorde deux poulies 89 montées sur le moyeu des disques 9 placés aux extrémités correspondantes des arbres 8, 88. Les deux chariots 5, 55 supportent au centre deux barres de soudage 50, 550 fixées au chariot respectif par un dispositif élastique 51, 551. L'une des barres au moins porte une lame de coupe 52 qui rentre et sort par une fente du chariot 55 sous la commande d'une came 56 montée sur l'arbre 88. Le mode de réalisation des figures 6 à 9 est différent de celui des figures 1 à 5 uniquement par le dispositif de manoeuvre des chariots 5 et 55 ; sur ces figures, les éléments analogues à ceux des figures 1 à 5 portent les mêmes références numériques. L'arbre 88 porte également dans ce cas une poulie intermédiaire 810 raccordée par une transmission à courroie 820 à une poulie 830 montée sur l'arbre du moteur 840 à avance commandée qui est lui-même commandé afin qu'il fasse tourner l'arbre 88 de 180'. Les figures 10 à 13 représentent un troisième mode de réalisation de l'invention qui diffère de celui des figures 6 à 9 par le fait que les supports 6, 66, les guides 4, 44 et les arbres 8, 88 ne sont pas solidaires des parois 7 de la machine, mais d'un châssis 700 qui est mobile verticalement.  The jack 86 communicates with the shaft 84 oscillations of 90 'which are transformed into oscillations of 180' of the shaft 88. The two shafts 8 and 88 are connected so that they rotate together by a belt transmission 87 which connects two pulleys 89 mounted on the hub of the discs 9 placed at the corresponding ends of the shafts 8, 88. The two carriages 5, 55 support in the center two welding bars 50, 550 fixed to the respective carriage by an elastic device 51, 551. The at least one of the bars carries a cutting blade 52 which enters and leaves through a slot of the carriage 55 under the control of a cam 56 mounted on the shaft 88. The embodiment of FIGS. 6 to 9 is different from that of the Figures 1 to 5 only by the operating device of the carriages 5 and 55; in these figures, elements similar to those of Figures 1 to 5 bear the same reference numerals. The shaft 88 also carries in this case an intermediate pulley 810 connected by a belt transmission 820 to a pulley 830 mounted on the shaft of the motor 840 controlled advance which is itself controlled so that it rotates the shaft 88 of 180 '. FIGS. 10 to 13 show a third embodiment of the invention which differs from that of FIGS. 6 to 9 in that the supports 6, 66, the guides 4, 44 and the shafts 8, 88 are not integral with the walls 7 of the machine, but a frame 700 which is vertically movable.

Le châssis 700 est suspendu aux parois 7 de la machine par deux bielles 701. Les extrémités supérieures des bielles 701 sont fixées à la paroi 7 de la machine tandis que les extrémités inférieures sont fixées de façon excentrique à des disques cor- respondants 702 montés à l'extrémité des arbres 8, 88 qui dépassent du châssis 700. Quatre guides verticaux 703 obligent le châssis 700 à se déplacer parallèlement à eux.  The frame 700 is suspended from the walls 7 of the machine by two connecting rods 701. The upper ends of the rods 701 are fixed to the wall 7 of the machine while the lower ends are eccentrically fixed to corresponding disks 702 mounted on the machine. the end of the shafts 8, 88 protruding from the frame 700. Four vertical guides 703 require the frame 700 to move parallel to them.

Le fonctionnement selon l'invention est le suivant. Après une opération de soudage et de coupe d'un dernier récipient (figure 3), le vérin 86 ou le moteur 84 qui provoque la rotation de 180' de l'arbre 88 est commandé de sorte que les chariots 5, 55 sont entraînés par les cames 91 et les toucheaux respectifs de came 92 et s'éloignent l'un de l'autre ; simultanément, le moteur 100 est commandé afin qu'il déplace les courroies opposées 3 qui entraînent vers le bas un morceau de structure tubulaire 2 correspondant au récipient suivant. Des dispositifs de type connu, non représentés, font descendre la quantité souhaitée du produit en vrac dans le récipient par le conduit 1 et, à ce moment, le vérin 86 ou le moteur 840 est commandé, de sorte que l'arbre 88 présente une rotation de 180' qui provoque le rapprochement des chariots avec mise des barres de soudage en contact mutuel afin que le récipient et l'extrémité inférieure de la structure tubulaire soient fermés. Des dispositifs de coupe de type connu, non représen- tés, séparent le récipient qui vient d'être rempli de l'extrémité inférieure fermée de la structure tubulaire, et le cycle recommence. Le fonctionnement de la machine des modes de réalisation des figures 1 à 9 est discontinu.  The operation according to the invention is as follows. After a welding and cutting operation of a last container (FIG. 3), the jack 86 or the motor 84 which causes the rotation of 180 'of the shaft 88 is controlled so that the carriages 5, 55 are driven by the cams 91 and the respective cam tabs 92 and move away from each other; simultaneously, the motor 100 is controlled so that it moves the opposed belts 3 which drive down a piece of tubular structure 2 corresponding to the next container. Devices of known type, not shown, lower the desired quantity of the bulk product in the container through the conduit 1 and, at this moment, the cylinder 86 or the motor 840 is controlled, so that the shaft 88 has a rotation 180 'which causes the approximation of the carriages with setting welding bars in contact with each other so that the container and the lower end of the tubular structure are closed. Cutting devices of known type, not shown, separate the container which has just been filled from the closed lower end of the tubular structure, and the cycle starts again. The operation of the machine of the embodiments of Figures 1 to 9 is discontinuous.

Le mode de réalisation des figures 10 à 13 permet un fonctionnement continu. En effet, la rotation des arbres 8, 88 par l'intermédiaire des disques 702 et des bielles 701 provoque un déplacement vertical du châssis 700 en synchronisme avec le déplacement des chariots 5, 55 et des barres de soudage respectives qui peuvent ainsi effectuer le soudage pendant que la structure tubulaire continue à descendre en étant commandée par les courroies 3.  The embodiment of Figures 10 to 13 allows continuous operation. Indeed, the rotation of the shafts 8, 88 by means of the disks 702 and the rods 701 causes a vertical displacement of the frame 700 in synchronism with the movement of the carriages 5, 55 and the respective welding bars which can thus perform the welding while the tubular structure continues to descend while being controlled by the belts 3.
